| ○ | ○ | Article | State-Constrained Lane Change Trajectory Planning for Emergency Steering on Slippery Roads | In this paper, a state-constrained optimal solution based real-time vehicle path planning strategy, which aids the vehicle to avoid collision by the lane change maneuver, is presented. More specifically, depending on the driving conditions, the path is generated by considering the elapsed time and the driver's ride quality. Especially, the path is planned based on the trajectory optimization theory (i.e., Pontryagin maximum principle), resulting in the analytical optimal solutions. Furthermore, to handle the state-constrained optimization problem that is considered to ensure the vehicle lateral stability, we include the punctual and isolated equality constraints in the formulated optimization problem, which can designate the state variables as the desired value at the intermediate time instants. Through the numerical examples on various driving conditions and high-fidelity model-based verification, we demonstrate the effectiveness of the developed path planner, and our approach can effectively generate a safe vehicle path rapidly, depending on the road surfaces and vehicle speeds. | Kim, Dongryul; Nguyen, Hung Duy; Han, Kyoungseok | Kyungpook Natl Univ, Dept Mech Engn, Daegu 41566, South Korea | ; Nguyen, Hung/JXL-7245-2024 | 58137887800; 57225877690; 56465294700 | ddyul@knu.ac.kr;nguyenduyhung@knu.ac.kr;kyoungsh@knu.ac.kr; | IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY | IEEE T VEH TECHNOL | 0018-9545 | 1939-9359 | 72 | 7 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;TRANSPORTATION SCIENCE & TECHNOLOGY | 2023 | 6.1 | 12.2 | 1.97 | 2025-06-25 | 10 | 15 | Emergency steering; obstacle collision avoidance; pontryagin maximum principle; trajectory optimization | MODEL-PREDICTIVE CONTROL; AUTONOMOUS VEHICLE; PATH; ALGORITHM; TRACKING; RRT | Emergency steering; obstacle collision avoidance; pontryagin maximum principle; trajectory optimization | Aerodynamics; Collision avoidance; Constrained optimization; Maximum principle; Motion planning; Optimal systems; Site selection; Steering; Trajectories; And emergency steering; Collisions avoidance; Minimisation; Obstacle collision; Obstacle collision avoidance; Optimisations; Pontryagin's maximum principle; Road; Stability analyze; Trajectory optimization; Automobile steering equipment | English | 2023 | 2023-07 | 10.1109/tvt.2023.3253212 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Sulfonated poly(p-phenylene)-based ionomer/PTFE composite membrane with enhanced performance and durability for energy conversion devices | Proton exchange membranes (PEMs) have to be fabricated as thin as possible to minimize the ohmic loss in the cell voltage of proton exchange membrane fuel cells (PEMFCs) and water electrolyzers (PEMWEs). Additionally, the dimensional and mechanical stabilities of the PEMs must be maintained because they are critical for pro-longing the cell lifespan in energy conversion devices that are used in moist environments. Herein, a sulfonated poly(p-phenylene)-based (SPP) multiblock ionomer is impregnated into a porous polytetrafluoroethylene (PTFE) substrate as a practical strategy for fabricating a mechanically robust and thin membrane. A five-layered structure is fabricated using two PTFE substrates as the composite membrane to increase the interfacial area between the SPP ionomer and PTFE; PTFE is treated with n-propyl alcohol to mediate the interfacial interactions between the two incompatible components. The composite membrane exhibits enhanced dimensional stability and mechanical properties compared with those of the pristine membrane owing to the SPP ionomer interlocking with PTFE. Regarding the electrochemical properties, the cell performance of the composite membrane displays a high current density of 1.52 A/cm(2) at 0.5 V and 7.90 A/cm(2) at 1.9 V for PEMFC and PEMWE, respectively; these densities are 32% and 16% greater, respectively, than that of Nafion212. | Noh, Yi Sak; Jeong, Hwan Yeop; Kim, Tae-Ho; Choi, Jaewon; Lee, Jang Yong; So, Soonyong; Yu, Duk Man | Korea Res Inst Chem Technol KRICT, Energy Mat Res Ctr, Daejeon 34114, South Korea; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu 41566, South Korea | LEE, JI SOOK/HOF-9112-2023; So, Soonyong/AAO-5321-2020 | 57985433900; 57193333422; 57189330960; 57210206972; 56083638300; 35077284800; 49865015000 | ljylee@krict.re.kr;syso@krict.re.kr;dmyu@krict.re.kr; | JOURNAL OF POWER SOURCES | J POWER SOURCES | 0378-7753 | 1873-2755 | 580 | SCIE | CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 8.1 | 12.2 | 1.62 | 2025-06-25 | 12 | 15 | Fuel cell; Water electrolyzer; Sulfonatedpoly(p-phenylene)-based ionomer; Porous PTFE; Composite membrane | POLY(ARYLENE ETHER SULFONE); FUEL-CELL PERFORMANCE; POLYMER ELECTROLYTE; MULTIBLOCK COPOLYMERS; HYDROCARBON MEMBRANES; STABILITY; MORPHOLOGY; BLOCK | Composite membrane; Fuel cell; Porous PTFE; Sulfonated poly(p-phenylene)-based ionomer; Water electrolyzer | Aromatic compounds; Biomechanics; Composite membranes; Electrolytic cells; Polytetrafluoroethylenes; Proton exchange membrane fuel cells (PEMFC); Substrates; Electrolyzers; Energy conversion devices; Poly (p-phenylene); Poly(p-phenylene)s; Polytetrafluoroethylene composites; Porous polytetrafluoroethylene; Proton exchange membranes; Proton-exchange membranes fuel cells; Sulphonated poly(p-phenylene)-based ionomer; Water electrolyzer; Ionomers | English | 2023 | 2023-10-01 | 10.1016/j.jpowsour.2023.233422 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Validity and reliability of the Korean version of authentic leadership among ICU nurses | Background: Authentic leadership affects the safety climate or job satisfaction of nurses, especially in intensive care unit (ICU). It is extremely challenging to find a suitable instrument for measuring authentic leadership among Korean nurses. Because the existing scales were developed within a Western cultural context and among business students, a new scale for measuring authentic leadership among Korean nurses must be evaluated. Objectives: This study aimed to assess the reliability of the Korean version of the Authentic Leadership Inventory (K-ALI) for ICU nurses. Design: A cross-sectional study and secondary data analysis were used. Methods: This study evaluated 203 ICU registered nurses from four South Korean university hospitals. The ALI developed by Neider and Schriesheim was developed. The reliability and validity of this scale were analyzed using Cronbach's alpha and factor analysis. Results: The factor analysis identified two subconstructs that accounted for 57.3 % of the total variance. The overall model fit indices for the K-ALI from the confirmatory factor analysis were an acceptable fit. Cronbach's alpha for the internal consistency of the reliability was 0.92. Conclusion: Using the K-ALI, nurses can assess authentic leadership and develop or demonstrate their professional leadership. | Lee, Junghoon; Song, Yeoungsuk | Keimyung Coll Univ, Dept Nursing, Daegu, South Korea; Kyungpook Natl Univ, Coll Nursing, Gukchaebosang Ro, Daegu 41944, South Korea | Song, Yeoungsuk/MSZ-3096-2025 | 57218996809; 55494171100 | asansong@knu.ac.kr; | APPLIED NURSING RESEARCH | APPL NURS RES | 0897-1897 | 1532-8201 | 72 | SCIE;SSCI | NURSING | 2023 | 2.7 | 12.2 | 0.32 | 2025-06-25 | 0 | 1 | Authentic leadership; Intensive care unit; Nurses; Reliability; Validity | MEDIATING ROLE; VALIDATION; INVENTORY | Authentic leadership; Intensive care unit; Nurses; Reliability; Validity | Cross-Sectional Studies; Humans; Intensive Care Units; Leadership; Nurses; Psychometrics; Reproducibility of Results; Republic of Korea; Surveys and Questionnaires; article; confirmatory factor analysis; Cronbach alpha coefficient; cross-sectional study; human; intensive care unit; internal consistency; leadership; nurse; registered nurse; reliability; secondary data analysis; university hospital; validity; intensive care unit; psychometry; questionnaire; reproducibility; South Korea | English | 2023 | 2023-08 | 10.1016/j.apnr.2023.151696 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Water splitting over an ultrasonically synthesized NiFe/MoO3@CFP electrocatalyst | The development of non-precious metal catalysts exhibiting high performance towards both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) has been recognized as one of the ultimate goals in water electrolysis research. Herein, we report on the synthesis of an efficient OER and HER catalyst, NiFe/MoO3@CFP, using a unique synthetic technique that combines ultrasonic synthesis and electrochemical deposition. The Mo-based compound, used as a template for the NiFe structure, was formed during the ultrasonication, and cavitation bubbles generated via ultrasonication were found to play a key role for improving the catalyst performance. NiFe/MoO3@CFP achieved a current density of 20 mA cm-2 for the OER and HER at low overpotentials of 251 and 204 mV, respectively. It was found that a cell potential of 1.589 V was required to achieve 10 mA cm-2 in the overall water splitting process. This study presents the effective preparation of a catalyst using ultrasound technology, which has rarely been used, suggesting its potential for future applications. & COPY; 2023 Hydrogen Energy Publications LLC.

| ○ | ○ | Article | ZnO@Ti3C2Tx MXene Hybrid Composite-Based Schottky-Barrier-Coated SAW Sensor for Effective Detection of Sub-ppb-Level NH3 at Room Temperature under UV Illumination | Smart sensors capable of detecting NH3 at sub-ppb levels are important for human health in our daily life. Here, we demonstrate a surface acoustic wave (SAW) sensor based on ZnO@MXene hybrid heterostructure for ultrahigh NH3 gas detection under UV illumination at room temperature (RT). Under UV illumination, the ZnO@MXene SAW sensor not only significantly enhances the frequency response (Delta f approximate to 32.24 kHz/20 ppm) but also effectively improves the selectivity with a low detection limit (89.41 ppb), short response/recovery times (92/104 s), long-term stability, and robust sensitivity under various relative humidity conditions (dark) to NH3 at RT. These unique NH3 sensing properties might be attributed to the enriched functional groups, oxygen vacancies, and excellent charge transfer at the Schottky barrier via band bending, which is explained using an energy band theory sensing mechanism. Overall, the current study offers strategic insights for designing light-activated high-performance SAW-based RT NH3 sensors in safety assurance and environmental monitoring. | Pasupuleti, Kedhareswara Sairam; Thomas, Alphi Maria; Vidyasagar, Devthade; Rao, Vempuluru Navakoteswara; Yoon, Soon-Gil; Kim, Young-Heon; Kim, Song-Gang; Kim, Moon-Deock | Chungnam Natl Univ, Inst Quantum Syst IQS, Daejeon 34134, South Korea; Chungnam Natl Univ, Dept Mat Sci & Engn, Daejeon 34134, South Korea; Kyungpook Natl Univ, Dept Mat Sci & Engn, Daegu 41566, South Korea; Indian Inst Technol Hyderabad, Dept Chem, Sangareddy 502285, India; Korea Adv Inst Sci & Technol KAIST, Natl Nanofab Ctr, Nanoconvergence Technol Div, Daejeon 34141, South Korea; Chungnam Natl Univ, Grad Sch Analyt Sci & Technol GRAST, Daejeon 34134, South Korea; Joongbu Univ, Dept Informat & Commun, Goyang 10279, Kyunggi Do, South Korea; Chungnam Natl Univ, Dept Phys, Daejeon 34134, South Korea | Vidyasagar, Devthade/O-3930-2015; Kim, Young Dok/ABG-8986-2021; Yoon, Sung Goo/AHC-1544-2022; Rao, vempuluru/HMD-1624-2023; Pasupuleti, Kedhareswara Sairam/ABE-6605-2021 | 57219936688; 57220944990; 57201674442; 57196196615; 55548955900; 57196172886; 37112351700; 24577628800 | mdkim@cnu.ac.kr; | ACS MATERIALS LETTERS | ACS MATER LETT | 2639-4979 | 5 | 10 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 9.9 | 12.2 | 6.66 | 2025-06-25 | 58 | 61 | NANOCOMPOSITES; NO2 | Acoustic surface wave devices; Acoustic waves; Ammonia; Charge transfer; Frequency response; II-VI semiconductors; Room temperature; Schottky barrier diodes; Titanium compounds; Coated surface; Daily lives; Gas detection; Human health; Hybrid composites; Low detection limit; Ppb levels; Schottky barriers; Surface acoustic wave sensors; UV illuminations; Zinc oxide | English | 2023 | 2023-09-08 | 10.1021/acsmaterialslett.3c00698 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Dental diagnosis for inlay restoration using an intraoral optical coherence tomography system: A case report | Patients: The patient was a 32-year-old man who underwent amalgam restoration of the mandibular right second molar. An amalgam restoration fracture was diagnosed by intraoral optical coherence tomography (OCT), and pulp exposure was examined during cavity preparation. Subsequently, a definitive ceramic restoration was fabricated, and the marginal fit in the oral cavity was evaluated using the OCT system. Discussion: The existing OCT system cannot acquire images inside the oral cavity because of the large probe size. However, the proposed intraoral OCT system can access the prostheses in the mandibular right second molar. Therefore, dental diagnosis for restoration treatment with dental prosthesis fracture, marginal gap, and pulp exposure after tooth preparation is possible using the proposed intraoral OCT system. Conclusions: The use of the intraoral OCT system improved dental diagnosis by allowing the dentist to confirm quantitative values through cross-sectional images, rather than that by determining a treatment plan after visual dental diagnosis. | Son, Keunbada; Cho, Hoseong; Kim, Hayoung; Lee, Weonjoon; Cho, Minsoo; Jeong, Hyosang; Kim, Kyoung Ho; Lee, Du-Hyeong; Kim, So-Yeun; Lee, Kyu-Bok; Jeon, Mansik; Kim, Jeehyun | Kyungpook Natl Univ, Adv Dent Device Dev Inst A3DI, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Coll IT Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Coll IT Engn, Daegu, South Korea; Huvitz Co Ltd, Anyang, Gyeonggi Do, South Korea | Son, Keunbada/AAG-8089-2019; SON, Keunbada/AAG-8089-2019 | 57202916520; 57209416599; 57214326551; 58183359900; 58183282000; 37561503300; 58183388400; 35770948000; 57190972249; 15925571200; 24171094000; 7601373350 | kblee@knu.ac.kr;msjeon@knu.ac.kr; | JOURNAL OF PROSTHODONTIC RESEARCH | J PROSTHODONT RES | 1883-1958 | 2212-4632 | 67 | 2 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2023 | 3.2 | 12.3 | 2.31 | 2025-06-25 | 5 | 7 | Optical coherence tomography; Dental diagnosis; Cross-sectional image; Fixed dental restoration | CRACKED-TOOTH; DEVICE | Cross-sectional image; Dental diagnosis; Fixed dental restoration; Optical coherence tomography | Adult; Dental Cavity Preparation; Humans; Inlays; Molar; Mouth; Tomography, Optical Coherence; adult; case report; dental inlay; dental surgery; human; molar tooth; mouth; optical coherence tomography; procedures | English | 2023 | 2023 | 10.2186/jpr.jpr_d_22_00008 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Fully digital workflow for the fabrication of a tooth-colored space maintainer for a young patient | Objectives Preventive orthodontic therapy with a band and loop is recommended to reduce the prevalence and severity of malocclusion on premature loss of a primary molar. However, when young patients are less cooperative and have a severe gag reflex, using traditional impression methods may be challenging. The use of a conventional metal space maintainer (SM) requires manual laboratory procedures and does not provide optimal esthetics. Moreover, gingival submergence of the wire and gingivitis caused by metal structures may occur. This clinical report describes a complete digital workflow for the fabrication of a zirconia SM to overcome these limitations. Clinical Considerations An 8-year-old boy with a band and loop SM for a missing primary mandibular right second molar presented with plaque accumulation around the band, soft tissue impingement by the loop, and loss of cement. A reverse band and loop SM had been proposed for the restoration of the primary mandibular right first molar. After conservative tooth preparation, a digital impression procedure was performed. A customized band and loop SM was designed using a computer-aided design software and milled out of the zirconia block. After sintering, the SM was luted with adhesive resin cement. Conclusions Using an intraoral scanner, computer-aided design, and computer-aided manufacturing technology, the limitations of traditional impression procedures were overcome, and a zirconia SM with mechanical, biological, and esthetic advantages was fabricated. Clinical Significance Advancements in dental materials and digital technologies allow for the efficient fabrication of a tooth-colored SM with an improved patient satisfaction and reduced human error. | Lee, Ju-Hyoung | Kyungpook Natl Univ, Sch Dent, Dept Predoctoral Clin Educ, 2177 Dalgubeol Daero, Daegu 41940, South Korea; Kyungpook Natl Univ, Dent Hosp, Daegu Dent Clin Ctr Disabled, Daegu, South Korea | 53866763700 | jus2u@knu.ac.kr; | JOURNAL OF ESTHETIC AND RESTORATIVE DENTISTRY | J ESTHET RESTOR DENT | 1496-4155 | 1708-8240 | 35 | 4 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2023 | 3.2 | 12.3 | 2.19 | 2025-06-25 | 10 | 9 | CAD; CAM; digital space maintainer; digital technology; esthetic dentistry; intraoral digital scanner | FIXED DENTAL PROSTHESES; STAINLESS-STEEL; ZIRCONIA; CROWNS; IMPRESSIONS; TRIAL | CAD/CAM; digital space maintainer; digital technology; esthetic dentistry; intraoral digital scanner | Child; Computer-Aided Design; Dental Prosthesis Design; Humans; Male; Workflow; Zirconium; resin cement; zirconium oxide; zirconium; Article; case report; child; clinical article; computer aided design; dental examination; human; male; malocclusion; mouth cavity; nanofabrication; patient satisfaction; plaque index; preoperative care; school child; soft tissue; tooth color; prosthesis design; workflow | English | 2023 | 2023-06 | 10.1111/jerd.12939 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Relationship between childhood trauma and resilience in patients with mood disorders | Background: Childhood trauma has lasting negative impacts on individuals' psychological functioning. However, there is limited empirical evidence on the association between childhood trauma and resilience and none examining such relationship among diverse clinical populations. This study aimed to investigate the relationship in patients with major depressive disorder, bipolar I disorder, bipolar II disorder, and a comparison group. Methods: In total, 787 psychiatric patients and 734 people from the general population participated in the study. The Childhood Trauma Questionnaire-Short Form and Connor-Davidson Resilience Scale were used to assess childhood trauma and resilience, respectively. Results: Individuals with childhood trauma showed lower levels of resilience in all subjects; among them, those who experienced emotional abuse and emotional neglect exhibited even stronger associations than other types of childhood trauma. There was a significant difference in the negative relationship between childhood trauma and resilience by group, where the association was more prominent in the comparison group than in MDD and BD II patient groups. Limitations: The generalizability of our results may be limited due to unproportionate patient sample size. Also, we could not examine the causal relationship between childhood trauma and resilience. Conclusion: Childhood trauma and resilience had a significantly negative association. Our results suggest that people who have experienced emotional abuse and emotional neglect should be closely assisted to develop resilience. Interventions that promote resilience should be provided to individuals predisposed to psychological risks as a result of childhood trauma. | Park, Ji Yoon; Lee, Chan Woo; Jang, Yoonjeong; Lee, Wonyun; Yu, Hyeona; Yoon, Joohyun; Oh, Sunghee; Park, Yun Seong; Ryoo, Hyun A.; Lee, Jangwon; Cho, Nayoung; Lee, Chong Hun; Lee, Yeong Chan; Won, Hong-Hee; Kang, Hyo Shin; Ha, Tae Hyon; Myung, Woojae | Seoul Natl Univ Bundang Hosp, Dept Neuropsychiat, Seongnam 13619, South Korea; Samsung Med Ctr, Res Inst Future Med, Seoul, South Korea; Sungkyunkwan Univ, Samsung Adv Inst Hlth Sci & Technol SAIHST, Samsung Med Ctr, Dept Digital Hlth, Seoul 06351, South Korea; Kyungpook Natl Univ, Dept Psychol, Daegu 41566, South Korea; Seoul Natl Univ, Coll Med, Dept Psychiat, Seoul 03080, South Korea; Seoul Natl Univ Bundang Hosp, Dept Neuropsychiat, 82 Gumi Ro 173beon Gil, Seongnam 13620, South Korea; Seoul Natl Univ, Coll Med, Dept Psychiat, 82 Gumi Ro 173beon Gil, Seongnam 13620, South Korea; Seoul Natl Univ Bundang Hosp, Dept Neuropsychiat, 82 Gumi Ro 173 Beon Gil, Seongnam Si 13619, Gyeonggi Do, South Korea; Seoul Natl Univ, Coll Med, Dept Psychiat, 82 Gumi Ro 173 Beon Gil, Seongnam Si 13619, Gyeonggi Do, South Korea | Park, Christopher/L-6074-2017; Won, Hong-Hee/D-2672-2011; Myung, Woojae/AAD-3016-2021; Ha, Tae/U-5558-2019; Jang, Yoonjeong/LKN-3419-2024 | 57230770600; 57230186200; 57223872445; 57230969500; 57910913300; 57226706803; 57213818920; 57212764489; 57230578700; 57915764600; 57230969400; 58040767100; 57210554111; 34573851600; 57219595147; 7203014550; 37099034100 | hatti@snu.ac.kr;wmyung@snu.ac.kr; | JOURNAL OF AFFECTIVE DISORDERS | J AFFECT DISORDERS | 0165-0327 | 1573-2517 | 323 | SCIE;SSCI | CLINICAL NEUROLOGY;PSYCHIATRY | 2023 | 4.9 | 12.3 | 0.64 | 2025-06-25 | 4 | 3 | Childhood trauma; Resilience; Major depressive disorder; Bipolar disorder | BIPOLAR DISORDER; DEPRESSIVE SYMPTOMS; LIFE STRESS; IMPACT; SENSITIZATION; EXPERIENCES; VALIDATION; EVENTS; SAMPLE | Bipolar disorder; Childhood trauma; Major depressive disorder; Resilience | Adverse Childhood Experiences; Bipolar Disorder; Child; Child Abuse; Depressive Disorder, Major; Humans; Mood Disorders; Resilience, Psychological; Surveys and Questionnaires; adolescent; adult; aged; Article; bipolar I disorder; bipolar II disorder; child abuse; childhood trauma; Childhood Trauma Questionnaire; comparative study; Connor Davidson resilience scale; controlled study; emotional abuse; emotional neglect; female; human; major clinical study; major depression; male; mental patient; physical abuse; population; psychological resilience; bipolar disorder; child; child abuse; complication; mood disorder; psychology; questionnaire | English | 2023 | 2023-02-15 | 10.1016/j.jad.2022.11.003 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Reliability of automatic finish line detection for tooth preparation in dental computer-aided software | Purpose: This study aimed to investigate the accuracy of automatic tooth finish line registration compared to manual registration with regard to various finish line configurations and dental computer-aided design (CAD) software.Methods: Finish line registrations were performed on 15 digital tooth models with different finish line configurations (edge roundness radius = 0 mm, 0.2 mm, and 0.4 mm; edge angle = 30 degrees, 60 degrees, 90 degrees, 120 degrees, and 150 degrees) using automatic and manual methods for designing virtual copings (N = 150). The discrepancies between the registered finish line extracted from the copings and the actual finish line segmented from the digitized tooth model were measured. Three-way analysis of variance (ANOVA) and post-hoc analyses with Bonferroni correction (alpha = 0.05) were used to analyze the results.Results: The finish line configurations, registration methods, and CAD software interacted with the accuracy of the reg-istered finish line (p = 0.001). The automatic finish line registration method exhibited larger error values than the manual method, especially at high finish line edge roundness and obtuse edge angles for both EXOCAD and R2CAD software (p < 0.001). The difference in dental CAD software affected the registration accuracy in the automatic method (p < 0.001), but not in the manual method (p = 0.676).Conclusions: Finish line registration errors may occur when the automatic registration method is applied to the indistinct edge of tooth preparation. The accuracy of the automatic finish line registration could differ according to the CAD soft-ware program. | Mai, Hang-Nga; Han, Jung-Suk; Kim, Hyeong-Seob; Park, Young-Seok; Park, Ji-Man; Lee, Du-Hyeong | Kyungpook Natl Univ, Inst Translat Res Dent, Daegu, South Korea; Seoul Natl Univ, Sch Dent, Dept Prosthodont, Seoul, South Korea; Seoul Natl Univ, Dent Res Inst, Seoul, South Korea; Kyung Hee Univ, Sch Dent, Dept Prosthodont, Seoul, South Korea; Seoul Natl Univ, Dent Res Inst, Ctr Future Dent, Dept Oral Anat,Sch Dent, Seoul, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, 2175 Dalgubeoldaero, Daegu 41940, South Korea; Kyungpook Natl Univ, Inst Translat Res Dent, Sch Dent, 2175 Dalgubeoldaero, Daegu 41940, South Korea | Park, Ji-Man/O-9279-2019; Mai, Hang-Nga/Q-9865-2018; Park, Ji-Man/J-3284-2015; Kim, Soo-Yeon/ADR-9663-2022; Park, Young-Seok/D-5762-2012 | 56964780900; 57954884200; 55330105000; 24176049400; 55839092400; 35770948000 | deweylee@knu.ac.kr; | JOURNAL OF PROSTHODONTIC RESEARCH | J PROSTHODONT RES | 1883-1958 | 2212-4632 | 67 | 1 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2023 | 3.2 | 12.3 | 3.47 | 2025-06-25 | 9 | 9 | Automatic; Tooth preparation; Finish line registration; Reliability; Dental computer-aided software | CROWNS; RESTORATIONS; ADAPTATION; ACCURACY; COPINGS | Automatic; Dental computer-aided software; Finish line registration; Reliability; Tooth preparation | Computer-Aided Design; Computers; Crowns; Dental Marginal Adaptation; Dental Prosthesis Design; Reproducibility of Results; Software; Tooth Preparation; Tooth Preparation, Prosthodontic; computer; computer aided design; dental marginal adaptation; dental surgery; procedures; prosthesis design; reproducibility; software; tooth crown | English | 2023 | 2023 | 10.2186/jpr.jpr_d_21_00344 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Temporal priority of lifetime alcohol use disorders and comorbid psychiatric disorders in adults: Results from a population-based nationwide survey in Korea | Background: Despite the high prevalence of alcohol use disorders (AUDs) in Korea, few studies have been conducted on the temporal priority with comorbid mental disorders. We investigated the temporal priority of lifetime AUDs and comorbid mood and anxiety disorders among the general population of Korea.Methods: Data of 18,807 respondents aged 18 years or older, collected from three national epidemiological surveys comprising face-to-face interviews using the Korean version of the Composite International Diagnostic Interview for DSM-IV mental disorders. For each mood or anxiety disorder, the extent to which one mental disorder precedes another was investigated by calculating the proportion of primary AUDs by that of primary mood or anxiety disorder.Results: Regarding alcohol dependence, dysthymic disorder is 5.6 times more likely to occur before alcohol dependence. Moreover, generalized anxiety disorder, social phobia, and specific phobia are 3.6 times, 4.5 times, and 6.3 times more likely to occur before, respectively. Regarding alcohol abuse, specific phobia is 6.3 times more likely to occur before, whereas major depressive disorder is two times more likely to occur after. Moreover, the lag times between primary alcohol abuse and subsequent mood or anxiety disorders were longer than those between primary alcohol dependence and the latter.Limitations: The age of onset might be subject to recall bias. The presence of non-respondents could have influenced the results. Conclusion: We need to recognize that one of the mental disorders could lead to another and consider it in the management of people with AUDs or mood and anxiety disorders. | Lee, Jimin; Kim, Byung-Soo; Hong, Jin Pyo; Cho, Seong-Jin; Lee, Jun-Young; Park, Jong-Ik; Jeon, Hong Jin; Chang, Sung Man | Kyungpook Natl Univ, Sch Med, Dept Psychiat, Daegu 700842, South Korea; Kyungpook Natl Univ Hosp, Dept Psychiat, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Dept Psychiat, Daegu, South Korea; Sungkyunkwan Univ, Sch Med, Samsung Med Ctr, Dept Psychiat, Seoul, South Korea; Gachon Univ, Coll Med, Gil Med Ctr, Dept Psychiat, Incheon 21565, South Korea; Seoul Natl Univ, Coll Med, Dept Psychiat, SMG SNU Boramae Med Ctr, Seoul 110744, South Korea; Kangwon Natl Univ, Sch Med, Dept Psychiat, Chunchon, South Korea; Sungkyunkwan Univ, Dept Psychiat, Depress Ctr, Samsung Med Ctr,Sch Med, Seoul 135710, South Korea; Kyungpook Natl Univ, Sch Med, Dept Psychiat, 680 Gukchaebosang Ro, Daegu 41944, South Korea | ; Kim, Byung-Soo/H-4047-2013; Lee, Jun-Young/N-5963-2019; Lee, Jun-Young/J-5604-2012 | 57219156372; 57214661242; 55729426400; 55572091200; 56117898800; 15036290300; 35195917400; 23092756400 | psyjang@knu.ac.kr; | JOURNAL OF AFFECTIVE DISORDERS | J AFFECT DISORDERS | 0165-0327 | 1573-2517 | 339 | SCIE;SSCI | CLINICAL NEUROLOGY;PSYCHIATRY | 2023 | 4.9 | 12.3 | 0.43 | 2025-06-25 | 2 | 2 | Comorbidity; Alcoholism; Mood disorders; Anxiety disorders; Causality; Korea | SUBSTANCE USE DISORDERS; AGE-OF-ONSET; GENERALIZED ANXIETY DISORDER; SELF-REPORTED AGE; EPIDEMIOLOGIC SURVEY; MENTAL-DISORDERS; PREVALENCE; DEPENDENCE; ABUSE; DEPRESSION | Alcoholism; Anxiety disorders; Causality; Comorbidity; Korea; Mood disorders | adult; agoraphobia; alcohol abuse; alcoholism; anxiety disorder; Article; DSM-IV; dysthymia; female; generalized anxiety disorder; human; interview; Korea; major clinical study; major depression; male; mental disease; mood disorder; obsessive compulsive disorder; onset age; panic; posttraumatic stress disorder; social phobia | English | 2023 | 2023-10-15 | 10.1016/j.jad.2023.07.051 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Gulp1 deficiency augments bone mass in male mice by affecting osteoclasts due to elevated 17β-estradiol levels | The engulfment adaptor phosphotyrosine-binding domain containing 1 (GULP1) is an adaptor protein involved in the engulfment of apoptotic cells via phagocytosis. Gulp1 was first found to promote the phagocytosis of apoptotic cells by macrophages, and its role in various tissues, including neurons and ovaries, has been well studied. However, the expression and function of GULP1 in bone tissue are poorly understood. Consequently, to determine whether GULP1 plays a role in the regulation of bone remodeling in vitro and in vivo, we generated Gulp1 knockout (KO) mice. Gulp1 was expressed in bone tissue, mainly in osteoblasts, while its expression is very low in osteoclasts. Microcomputed tomography and histomorphometry analysis in 8-week-old male Gulp1 KO mice revealed a high bone mass in comparison with male wild-type (WT) mice. This was a result of decreased osteoclast differentiation and function in vivo and in vitro as confirmed by a reduced actin ring and microtubule formation in osteoclasts. Gas chromatography-mass spectrometry analysis further showed that both 17 beta-estradiol (E2) and 2-hydroxyestradiol levels, and the E2/testosterone metabolic ratio, reflecting aromatase activity, were also higher in the bone marrow of male Gulp1 KO mice than in male WT mice. Consistent with mass spectrometry analysis, aromatase enzymatic activity was significantly higher in the bone marrow of male Gulp1 KO mice. Altogether, our results suggest that GULP1 deficiency decreases the differentiation and function of osteoclasts themselves and increases sex steroid hormone-mediated inhibition of osteoclast differentiation and function, rather than affecting osteoblasts, resulting in a high bone mass in male mice. To the best of our knowledge, this is the first study to explore the direct and indirect roles of GULP1 in bone remodeling, providing new insights into its regulation. | Kim, Soon-Young; Park, Gun-Il; Park, Seung-Yoon; Lee, Eun-Hye; Choi, Hyuck; Koh, Jeong-Tae; Han, Soyun; Choi, Man Ho; Park, Eui Kyun; Kim, In-San; Kim, Jung-Eun | Kyungpook Natl Univ, Sch Med, Cell & Matrix Res Inst, Dept Mol Med, Daegu, South Korea; Kyungpook Natl Univ, Dept Biomed Sci, BK21 KNU Convergence Educ Program Biomed Sci Creat, Daegu, South Korea; Dongguk Univ, Sch Med, Dept Biochem, Gyeongju, South Korea; Chonnam Natl Univ, Sch Dent, Dept Pharmacol & Dent Therapeut, Gwangju, South Korea; Korea Inst Sci & Technol, Mol Recognit Res Ctr, Seoul, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral Pathol & Regenerat Med, Daegu, South Korea; Korea Inst Sci & Technol, Biomed Res Inst, Ctr Theragnosis, Seoul, South Korea; Korea Univ, KU KIST Grad Sch Converging Sci & Technol, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Cell & Matrix Res Inst, Dept Mol Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea | Kim, Sang/HSD-0402-2023 | 57204021560; 58133168400; 8627776300; 57189661699; 56122848500; 7201756951; 57218853160; 7402093717; 37071072400; 34770432800; 57209054588 | kjeun@knu.ac.kr; | JOURNAL OF CELLULAR PHYSIOLOGY | J CELL PHYSIOL | 0021-9541 | 1097-4652 | 238 | 5 | SCIE | CELL BIOLOGY;PHYSIOLOGY | 2023 | 4.5 | 12.4 | 0.97 | 2025-06-25 | 6 | 6 | 17 beta-estradiol; adaptor protein; deficiency; Gulp1; osteoclast | ADAPTER PROTEIN GULP; SEALING ZONE; APOPTOTIC CELLS; MINERAL DENSITY; ASSOCIATION; ENGULFMENT; EXPRESSION; ESTROGEN; HORMONE; ESTRADIOL | 17β-estradiol; adaptor protein; deficiency; Gulp1; osteoclast | Animals; Aromatase; Bone and Bones; Cell Differentiation; Male; Mice; Mice, Knockout; Osteoblasts; Osteoclasts; X-Ray Microtomography; acp5 protein; actin; adaptor protein; aromatase; brexanolone; cathepsin K; collagen type 1; collagen type I alpha 1 chain; corticosterone; cre recombinase; dendritic cell specific transmembrane protein; engulfment adaptor phosphotyrosine binding domain containing 1; estradiol; estriol; genomic DNA; glyceraldehyde 3 phosphate dehydrogenase; messenger RNA; osteocalcin; osteoclast differentiation factor; osteoprotegerin; phosphoglycerate kinase; prasterone; pregnenolone; protamine; recombinase; sex hormone; testosterone; transcription factor NFAT; transcription factor NFAT1; unclassified drug; aromatase; adult; animal cell; animal experiment; animal model; Article; bone marrow; bone mass; bone remodeling; bone tissue; bone volume; cell differentiation; cell function; comparative study; confocal laser scanning microscopy; controlled study; cortical bone; distal femur; DNA sequencing; enzyme activity; estradiol blood level; fourth lumbar vertebra; immunofluorescence; in vitro study; in vivo study; lumbar vertebra; male; mass fragmentography; mass spectrometry; mesenchymal stem cell; metabolic ratio; micro-computed tomography; microtubule; morphometry; mouse; nerve cell; nonhuman; osteoblast; osteoclast; osteoclastogenesis; phagocytosis; proximal tibia; steroid metabolism; trabecular bone; trabecular number; trabecular separation; animal; bone; genetics; knockout mouse; metabolism | English | 2023 | 2023-05 | 10.1002/jcp.30987 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | The role of O-GlcNAcylation mediated by OGT during tooth development | To understand the mechanisms underlying tooth morphogenesis, we examined the developmental roles of important posttranslational modification, O-GlcNAcylation, which regulates protein stability and activity by the addition and removal of a single sugar (O-GlcNAc) to the serine or threonine residue of the intracellular proteins. Tissue and developmental stage-specific immunostaining results against O-GlcNAc and O-GlcNAc transferase (OGT) in developing tooth germs would suggest that O-GlcNAcylation is involved in tooth morphogenesis, particularly in the cap and secretory stage. To evaluate the developmental function of OGT-mediated O-GlcNAcylation, we employed an in vitro tooth germ culture method at E14.5, cap stage before secretory stage, for 1 and 2 days, with or without OSMI-1, a small molecule OGT inhibitor. To examine the mineralization levels and morphological changes, we performed renal capsule transplantation for one and three weeks after 2 days of in vitro culture at E14.5 with OSMI-1 treatment. After OGT inhibition, morphological and molecular alterations were examined using histology, immunohistochemistry, real-time quantitative polymerase chain reaction, in situ hybridization, scanning electron microscopy, and ground sectioning. Overall, inhibition of OGT resulted in altered cellular physiology, including proliferation, apoptosis, and epithelial rearrangements, with significant changes in the expression patterns of beta-catenin, fibroblast growth factor 4 (fgf4), and sonic hedgehog (Shh). Moreover, renal capsule transplantation and immunolocalizations of Amelogenin and Nestin results revealed that OGT-inhibited tooth germs at cap stage exhibited with structural changes in cuspal morphogenesis, amelogenesis, and dentinogenesis of the mineralized tooth. Overall, we suggest that OGT-mediated O-GlcNAcylation regulates cell signaling and physiology in primary enamel knot during tooth development, thus playing an important role in mouse molar morphogenesis. | Pokharel, Elina; Aryal, Yam P.

| ○ | ○ | Article | A multi-band study and exploration of the radio wave-γ-ray connection in 3C 84 | Total intensity variability light curves offer a unique insight into the ongoing debate about the launching mechanism of jets. For this work, we utilised the availability of radio and gamma-ray light curves over a few decades of the radio source 3C 84 (NGC 1275). We calculated the multi-band time-lags between the flares identified in the light curves via discrete cross-correlation and Gaussian process regression. We find that the jet particle and magnetic field energy densities are in equipartition (k(r) = 1.08 +/- 0.18). The jet apex is located z(91.5 GHz) = 22-645 R-s (2 - 20 x 10(-3) pc) upstream of the 3 mm radio core; at that position, the magnetic field amplitude is B-core(91.5 GHz) = 3-10G. Our results are in good agreement with earlier studies that utilised very-long-baseline interferometry. Furthermore, we investigated the temporal relation between the ejection of radio and gamma-ray flares. Our results are in favour of the gamma-ray emission being associated with the radio emission. We are able to tentatively connect the ejection of features identified at 43 and 86 GHz to prominent gamma-ray flares. Finally, we computed the multiplicity parameter lambda and the Michel magnetisation sigma(M), and find that they are consistent with a jet launched by the Blandford & Znajek (1977, MNRAS, 179, 433) mechanism. | Paraschos, G.

| ○ | ○ | Article | A new method for age-dating the formation of bars in disc galaxies The TIMER view on NGC1433's old bar and the inside-out growth of its nuclear disc | The epoch in which galactic discs settle is a major benchmark for testing models of galaxy formation and evolution but remains largely unknown. Once discs settle and become sufficiently self-gravitating, stellar bars are able to form; therefore, determining the ages of bars can shed light on the epoch of disc settling, and on the onset of secular evolution. Nevertheless, timing when the bar formed has proven challenging. In this work we present a new methodology for obtaining the bar age, using the star formation history of nuclear discs. Nuclear discs are rotation-supported structures, built by gas pushed to the centre via bar-induced torques, and their formation is thus coincident with bar formation. In particular, we used integral field spectroscopic data from the TIMER survey to disentangle the star formation history of the nuclear disc from that of the underlying main disc, which enables us to more accurately determine when the nuclear disc formed. We demonstrate the methodology on the galaxy NGC 1433 - which we find to host an old bar that is 7.5(-1.1)(+1.6)(sys)(-0.5)(+0.2)(stat) Gyr old - and describe a number of tests carried out on both the observational data and numerical simulations. In addition, we present evidence that the nuclear disc of NGC 1433 grows in accordance with an inside-out formation scenario. This methodology is applicable to high-resolution integral field spectroscopic data of barred galaxies with nuclear discs, making it ideally suited for the TIMER survey sample. In the future we will thus be able to determine the bar age for a large sample of galaxies, shedding light on the epoch of disc settling and bar formation. | de Sa-Freitas, Camila; Fragkoudi, Francesca; Gadotti, Dimitri A.; Falcon-Barroso, Jesus; Bittner, Adrian; Sanchez-Blazquez, Patricia; van de Ven, Glenn; Bieri, Rebekka; Coccato, Lodovico; Coelho, Paula; Fahrion, Katja; Goncalves, Geraldo; Kim, Taehyun; de Lorenzo-Caceres, Adriana; Martig, Marie; Martin-Navarro, Ignacio; Mendez-Abreu, Jairo; Neumann, Justus; Querejeta, Miguel | European Southern Observ, Karl Schwarzschild Str 2, D-85748 Garching, Germany; Univ Durham, Inst Computat Cosmol, Dept Phys, South Rd, Durham DH1 3LE, England; Max Planck Inst Astrophys, Karl Schwarzschild Str 1, D-85748 Garching, Germany; Univ Durham, Ctr Extragalact Astron, Dept Phys, South Rd, Durham DH1 3LE, England; Inst Astrofis Canarias, Calle Via Lactea S-N, Tenerife 38205, Spain; Univ La Laguna, Dept Astrofis, Tenerife 38200, Spain; Vyoma GmbH, Karl Theodor Str 55, D-80803 Munich, Germany; Univ Complutense Madrid, Dept Fis Tierra & Astrofis, Madrid 28040, Spain; Univ Complutense Madrid, Inst Fis Particulas & Cosmos IPARCOS, Madrid 28040, Spain; Univ Vienna, Dept Astrophys, Turkenschanzstr 17, A-1180 Vienna, Austria; Univ Sao Paulo, Inst Astron Geofis & Ciencias Atmosfer, Rua Matao 1226, BR-05508090 Sao Paulo, SP, Brazil; European Space Agcy, European Space Res & Technol Ctr, Keplerlaan 1, NL-2200 AG Noordwijk, Netherlands; Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea; Liverpool John Moores Univ, Astrophys Res Inst, IC2 Liverpool Sci Pk,146 Brownlow Hill, Liverpool L3 5RF, Merseyside, England; Max Planck Inst Astron, Konigstuhl 17, D-69117 Heidelberg, Germany; Univ Portsmouth, Inst Cosmol & Gravitat, Burnaby Rd, Portsmouth PO1 3FX, Hants, England; Observ Astron Nacl, C Alfonso XII 3, Madrid 28014, Spain | ; Falcon-Barroso, Jesus/AAD-9660-2019; Coelho, Paula/B-1592-2015; Martin-Navarro, Ignacio/F-5882-2016; Sanchez-Blazquez, Patricia/IYS-6088-2023; van de Ven, Glenn/R-5189-2019; de Lorenzo-Cáceres, Adriana/AAA-6412-2020; Querejeta, Miguel/KVY-3638-2024 | 57211524578; 55062198600; 55887354100; 6602632408; 57203535764; 16319840900; 18038742400; 56941654100; 16232259100; 23011441600; 57193391106; 57220104062; 57050549000; 23088009300; 25824385000; 55498121400; 23051261000; 56514665700; 35424450700 | camila.desafreitas@eso.org; | ASTRONOMY & ASTROPHYSICS | ASTRON ASTROPHYS | 0004-6361 | 1432-0746 | 671 | SCIE | ASTRONOMY & ASTROPHYSICS | 2023 | 5.4 | 12.5 | 1.66 | 2025-06-25 | 9 | 15 | galaxies: bulges; galaxies: evolution; galaxies: formation; galaxies: kinematics and dynamics; galaxies: stellar content; galaxies: structure | STELLAR EVOLUTION DATABASE; SIMILAR-TO 2; INTEGRAL FIELD SPECTROSCOPY; STAR-FORMATION; SPITZER SURVEY; POPULATION SYNTHESIS; SECULAR EVOLUTION; BOXY/PEANUT BULGES; FORMATION HISTORY; RADIAL MIGRATION | Galaxies: bulges; Galaxies: evolution; Galaxies: formation; Galaxies: kinematics and dynamics; Galaxies: stellar content; Galaxies: structure | Galaxies; Age dating; Galaxies: Kinematics and dynamics; Galaxies:structure; Galaxy evolution; Galaxy formations; Galaxy:bulge; Galaxy:stellar content; Integral field; Spectroscopic data; Stars formation; Stars | English | 2023 | 2023-02-27 | 10.1051/0004-6361/202244667 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Enhancing carotenoid production and exploring the potential use of microalga Desmodesmus cf. pleiomorphus DSHM22 as a biodiesel feedstock through photoheterotrophic cultivation | Improving biomass and value-added compound production is crucial for the industrial application of microalgae, achieved through the utilization of low-cost nutrients and various cultivation modes. This study aimed to enhance the biomass and biochemical production of the indigenous microalgae by comparing different cultivation modes. Among six algal strains obtained from the East Sea in South Korea, Desmodesmus cf. pleiomorphus DSHM22 exhibited the highest biomass productivity (0.0118 g L-1 d-1) and was selected for optimization. Algal growth responses were assessed under four commercially available soluble fertilizer media to identify a costeffective nutrient substrate. The most effective fertilizer demonstrated 2.2-fold higher growth compared to the BG-11 algal medium after 14 days. Glucose was supplemented in the culture medium to evaluate organic carbon availability under light and dark conditions. While no growth responses were observed under glucosesupplemented dark condition, the highest biomass production (approximately 1.22 g L-1) was achieved under glucose-supplemented light condition. The algal strain showed growth under both photoautotrophic (PA) and photoheterotrophic (PH) conditions, excluding the heterotrophic mode. Biochemical accumulations were compared by analyzing photosynthetic pigments and fatty acids under both PA and PH modes. The algal strain effectively produced lutein, neoxanthin, and omega-3, 6, and 9 fatty acids. Although PH condition yielded significantly higher biochemicals and lipid production compared to PA condition, both culture conditions exhibited similar fatty acid compositions and biodiesel properties. This study suggests that PH cultivation is an effective approach for producing value-added biochemicals and biodiesel using microalga D. cf. pleiomorphus DSHM22. | Kim, Eun Song; Ki, Hyunji; Lee, Chung Hyeon; An, Sung Min; Kang, Nam Seon; Choi, Grace; Hong, Ji Won; Pan, Cheol-Ho; Park, Bum Soo; Cho, Kichul | Natl Marine Biodivers Inst Korea, Dept Microbial Resources, Seocheon 33662, South Korea; Hanyang Univ, Dept Environm Sci, Seoul 04763, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea; Microalgae Ask Us Co Ltd, Kangnung 25441, South Korea; Hanyang Univ, Coll Nat Sci, Dept Life Sci, Seoul 04763, South Korea; Hanyang Univ, Hanyang Inst Biosci & Biotechnol, Seoul 04763, South Korea | ; PARK, Bum Soo/W-3178-2017; Park, Bum/W-3178-2017; An, Sung-Min/AAC-3888-2021; Cho, Kichul/IXD-8135-2023 | 57212380771; 57981461300; 58482939500; 56493979500; 7102653317; 57194561009; 57201579963; 7403224341; 37043854000; 55877400600 | kichul.cho@mabik.re.kr; | BIOMASS & BIOENERGY | BIOMASS BIOENERG | 0961-9534 | 1873-2909 | 177 | SCIE | AGRICULTURAL ENGINEERING;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;ENERGY & FUELS | 2023 | 5.8 | 12.5 | 0.42 | 2025-06-25 | 3 | 3 | Biodiesel; Carotenoids; Cultivation mode; Fatty acid; Photoheterotrophic | COMMERCIAL APPLICATIONS; BIOMASS PRODUCTIVITY; HETEROTROPHIC GROWTH; LIPID-ACCUMULATION; LINOLEIC-ACID; GREEN-ALGAE; CULTURES; GLUCOSE; SPHAEROPLEALES; SCENEDESMUS | Biodiesel; Carotenoids; Cultivation mode; Fatty acid; Photoheterotrophic | Pacific Ocean; Sea of Japan; South Korea; Algae; Biodiesel; Biomass; Cost effectiveness; Ecology; Fatty acids; Fertilizers; Glucose; Microorganisms; Nutrients; Organic carbon; Biodiesel feedstock; Carotenoid production; Condition; Cultivation modes; Dark conditions; Growth response; Light conditions; Micro-algae; Microalga; Photoheterotrophic; biofuel; biological production; carotenoid; cultivation; fatty acid; growth response; heterotrophy; microalga; organic carbon; Carotenoids | English | 2023 | 2023-10 | 10.1016/j.biombioe.2023.106939 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
