| ○ | ○ | Article | Effect of Mn Substitution on the Dielectric Constant and Breakdown Voltage of Anti-ferroelectric PLZT | Anti-ferroelectric (PbLa)(ZrTi)O-3 (PLZT) is a promising material for use in multilayer ceramic capacitors (MLCCs) for electric vehicles, as its dielectric and polarization properties are enhanced under high electric fields. To facilitate the commercialization of Cu-MLCCs, sintering in a reduction atmosphere is necessary. In this study, the effect of adding Mn ions in varying concentrations (ranging from a small amount to an excess of 2.0 mol.%, 3.0 mol.%, 5.0 mol.%, 10.0 mol.%, and 20.0 mol.%) on the dielectric constant and breakdown voltage was investigated to understand their behavior under high electric fields. Regardless of the amount of Mn ions added, a single perovskite structure with no secondary phase was observed. These oxygen vacancies originated from the ions occupying the B-site in the perovskite structure, thereby influencing the dielectric properties and breakdown voltage. Interestingly, the breakdown voltage improved significantly, reaching up to 8.0 kV/mm, and no phase transition to the ferroelectric state occurred, regardless of the amount of Mn ions substituted. Overall, it was evident that the anti-ferroelectric properties of PLZT were well maintained. | Choi, Jeoung Sik; Kim, Dong Chul; Shin, Hyo Soon; Kim, Hyungsuk K.

| ○ | ○ | Article; Retracted Publication | RETRACTED: Intra- and Interrater Agreement of Face Esthetic Analysis in 3D Face Images (Retracted Article) | The use of three-dimensional (3D) facial scans for facial analysis is increasing in maxillofacial treatment. The aim of this study was to investigate the consistency of two-dimensional (2D) and 3D facial analyses performed by multiple raters. Six men and four women (25-36-year-old) participated in this study. The 2D images of the smiling and resting faces in the frontal and sagittal planes were obtained. The 3D facial and intraoral scans were merged to generate virtual 3D faces. Ten clinicians performed facial analyses by investigating 14 indices of 2D and 3D faces. Intra- and interrater agreements of the results of 2D and 3D facial analyses within and among the participants were evaluated. The intrarater agreement between the 2D and 3D facial analyses varied according to the indices. The highest and lowest agreements were found for the dental crowding index (0.94) and smile line curvature index (0.56) in the frontal plane, and Angle's classification (canine) index (0.98) and occlusal plane angle index (0.55) in the profile plane. In the frontal plane, the interrater agreements were generally higher for the 3D images than for the 2D images, while in the profile plane, the interrater agreements were high in the Angle's classification (canine) index however low in the other indices. Several occlusion-related indices were missing in the 2D images because the posterior teeth were not observed. Esthetic analysis results between 2D and 3D face images can differ according to the evaluation indices. The use of 3D faces is recommended over 2D images to increase the reliability of facial analyses, as it can fully assess both esthetic and occlusion-related indices. | Park, Minsoo; Mai, Hang-Nga; Mai, Mai Yen; Win, Thaw Thaw; Lee, Du-Hyeong; Lee, Cheong-Hee | Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, 2177 Dalgubeoldae ro, Daegu 41940, South Korea; Hanoi Univ Business & Technol, Dent Sch, Hanoi 10000, Vietnam; Kyungpook Natl Univ, Inst Translat Res Dent, 2177 Dalgubeoldae ro, Daegu 41940, South Korea | Mai, Hang-Nga/Q-9865-2018; Win, Thin/GSJ-3091-2022 | 58189984300; 56964780900; 57217872800; 58157726100; 35770948000; 56101128900 | fighters2022@naver.com;mai.hang.nga1403@gmail.com;maihaiyen30061989@gmail.com;thawthawwin.mdy@gmail.com;deweylee@knu.ac.kr;chlee@knu.ac.kr; | BIOMED RESEARCH INTERNATIONAL | BIOMED RES INT | 2314-6133 | 2314-6141 | 2023 | ESCI | BIOTECHNOLOGY & APPLIED MICROBIOLOGY;MEDICINE, RESEARCH & EXPERIMENTAL | 2023 | 2.6 | 52.1 | 0 | 2025-06-25 | 1 | 0 | Esthetics; Female; Humans; Imaging, Three-Dimensional; Malocclusion; Reproducibility of Results; Smiling; adult; Angle classification (canine) index; anthropometric parameters; Article; canine tooth; clinician; commissural line; crowding (tooth); dental crowding index; dental parameters; esthetics; face asymmetry; facial expression; female; first molar; Frankfort mandibular plane angle; human; image analysis; interpupillary line; interrater reliability; intrarater reliability; lip line level; male; midline deviation; occlusal plane angle index; smile line curvature index; three-dimensional imaging; tooth arch; tooth occlusion; two-dimensional imaging; esthetics; facial expression; malocclusion; procedures; reproducibility | English | 2023 | 2023-04-10 | 10.1155/2023/3717442 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | GENDER DIFFERENCES IN EXPERIENCES OF 6TH-GRADE STUDENTS INQUIRY ACTIVITIES IN THE REPUBLIC OF KOREA | Each student's individual experience in learning is very important. Lower secondary school students are engaged in activities that focus on inquiry rather than the acquisition of scientific knowledge in science classrooms. Therefore, the experiences and thoughts of lower secondary school students in the stage of scientific inquiry need to be analyzed. To this end, the internal and external experiences of students in the stages of observation, variable control, and conclusion drawing were analyzed through candle-burning experiments. Seventy-seven 6th-grade students were used as participants. The main activities; main actions; main thoughts; and contribution of actions, consciousness, and emotions were analyzed. No differences were observed in the external and internal experiences of male and female students in each stage of the inquiry activities. There were many cases in which other activities related to the inquiry were carried out in addition to the activities that were mainly performed at the corresponding stage. About 1/4 of the participants had internal experiences unrelated to inquiry. The results showed that interaction needs to be increased by including the variable control stage in the inquiry activities. Given that there were no differences in the external and internal experiences of male and female students, equal inquiry activities without gender discrimination can be achieved. | Lim, Soo-min; Kim, Youngshin | Kyungpook Natl Univ, Sci Educ Res Inst, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Educ, Dept Biol Educ, 80 Daehakro, Daegu 41566, South Korea | 55681196400; 55682233400 | bbolsar@naver.com;kys5912@knu.ac.kr; | JOURNAL OF BALTIC SCIENCE EDUCATION | J BALT SCI EDUC | 1648-3898 | 22 | 5 | SSCI | EDUCATION & EDUCATIONAL RESEARCH | 2023 | 1.1 | 52.3 | 0 | 2025-06-25 | 0 | 0 | internal experience; external experience; inquiry stage; gender difference | SCIENCE; DISCOURSE; RESPONSES; MOOD | external experience; gender difference; inquiry stage; internal experience | English | 2023 | 2023 | 10.33225/jbse/23.22.881 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Experimental investigation of the effect of mechanical vibration and rotating magnetic field on the hydrothermal performance of water-Fe3O4 ferrofluid inside a rifled tube | Vibration can enhance the hydrothermal performance by disturbing the thermal boundary layer. Also, the magnetic field increases the ferrofluid mixing, thereby enhancing the heat transfer rate. In this study, an experimental analysis of ferrofluid flow inside a rifled tube under the vibration and rotational magnetic field (RMF) effects was conducted by considering different Reynolds numbers (Re), nanoparticle concentrations (phi), and rifled tube pitches (P). In the first stage, the effect of Re and phi on the hydrothermal performance of the system in the absence of the vibration and RMF was explored. In the second stage, the effect of vibration on the performance evaluation criterion (PEC) of the system was investigated. Finally, the RMF effect was considered. Based on the results, the system with P = 5 mm showed the highest PEC in all experiments. The highest PEC without the vibration and RMF effects was obtained as 1.62 for P = 5 mm and phi = 0% at Re = 2000. The highest PEC under the vibration effect (1.28) was also found for Re = 2000 but at phi of 2%, when the highest vibration acceleration (5 m/s2) was applied. Among the RMFs examined, the RMF with the counter clock-wise along with the counter clock-wise fluid flow inside the rifled tube resulted in the highest PEC of 1.62. RMF improved the PEC of the system from 1.28 to 1.62, corresponding to a 21.32% increase, under the vibration. | Shahsavar, Amin; Askari, Ighball Baniasad; Ghodrat, Maryam; Arici, Muesluem; Nizetic, Sandro; Rehman, Tauseef-ur; Ma, Zhenjun | Kermanshah Univ Technol, Mech Engn Dept, Kermanshah, Iran; Univ Zabol, Fac Engn, Dept Mech Engn, Zabol, Iran; UNSW Canberra, Sch Engn & Informat Technol, Canberra, ACT 2600, Australia; Kocaeli Univ, Engn Fac, Mech Engn Dept, TR-41001 Izmit, Kocaeli, Turkiye; Univ Split, FESB, Rudjera Boskov 32, Split 21000, Croatia; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Univ Wollongong, Sustainable Bldg Res Ctr, Wollongong, NSW, Australia | Ma, Zhenjun/M-5878-2014; Arici, Muslum/F-5172-2018; Rehman, Tauseef-ur/AAE-3086-2022; Nižetić, Sandro/G-4810-2017; Arıcı, Müslüm/AAE-1546-2020 | 36523886500; 33567500100; 57064280500; 36093844300; 24449457500; 57159403400; 22954433600 | muslumarici@gmail.com; | JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS | J MAGN MAGN MATER | 0304-8853 | 1873-4766 | 572 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, CONDENSED MATTER | 2023 | 2.5 | 52.5 | 2.43 | 2025-06-25 | 18 | 19 | Experimental study; Heat transfer; Magnetic field; Nanofluid; Rifled tube; Vibration | HEAT-TRANSFER CHARACTERISTICS; NANOFLUID FLOW | Experimental study; Heat transfer; Magnetic field; Nanofluid; Rifled tube; Vibration | Acceleration; Boundary layers; Clocks; Flow of fluids; Heat transfer; Magnetic field effects; Magnetite; Tubes (components); Vibration analysis; Counter-clockwise; Experimental study; Magnetic-field; Magnetic-field effects; Nanofluids; Performance; Performance evaluation criteria; Rifled tube; Rotational magnetic field; Vibration; Reynolds number | English | 2023 | 2023-04-15 | 10.1016/j.jmmm.2023.170586 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Boomerang latissimus dorsi flap in immediate or delayed breast reconstruction | Background: Breast reconstruction using the latissimus dorsi (LD) flap is one of the most popular and common breast reconstruction techniques among Asian patients. There are increasing numbers of cases wherein breasts need to be reconstructed to moderate to large sizes among the Asian population. Most reconstructive surgeons use abdominal-based flaps-such as the deep inferior epigastric perforator and transverse rectus abdominis myocutaneous flap, or LD flap with an implant-to supplement the volume. Here, we compare the usefulness of the boomerang LD (bLD) flap-a technique developed by modifying the design of the conventional extended LD flap-with that of the LD flap with implant (LDi). Methods: This was a prospective cohort study including patients with breast cancer aged between 25 and 60 years who underwent unilateral total or skin/nipple-sparing mastectomy, or postmastectomy. The exclusion criteria were advanced breast cancer (stages 3 and 4); a history of cognitive impairment affecting ability to complete the self-reported questionnaire; a history of neurologic or musculoskeletal disorder; and a history of alcohol or drug abuse. Statistical analysis was performed, and correlations between the two technique types were analyzed [including age, body mass index, preoperative breast volume, operation time, flap elevation time, admission duration, adjuvant treatment (radiotherapy, chemotherapy), drain indwelling duration, and drain total sum volume]. Results: In total, 85 patients who underwent immediate breast construction through the LDi group (n=63) or bLD group (n=25) techniques after total mastectomy between January 2015 and June 2022 were analyzed (mean age: LDi group, 46 & PLUSMN;7.7 years; bLD group, 45.6 & PLUSMN;7.8 years). We observed that the flap weight, operative time, mean admission duration, and drain indwelling duration were statistically significantly different in the bLD group (P<0.05). Body mass index, preoperative breast volume, specimen weight, flap elevation time, and drain total time were comparable between groups. Conclusions: Breast reconstruction using the bLD flap was found to be a suitable alternative technique for patients who desire an autologous tissue transfer (rather than an implant) but are contraindicated for abdominal-based flaps and do not mind long postoperative scars. | Kim, Hyunbin; Eo, Philseon; Ryu, Jeong Yeop; Choi, Kang Young; Yang, Jung Dug; Chung, Ho Yun; Cho, Byung Chae; Kang, Byeongju; Lee, Jeeyeon; Park, Ho Yong; Lee, Joon Seok | Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Surg, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Plast & Reconstruct Surg, 807 Hoguk Ro, Daegu 41404, South Korea | Lee, Jong-Mok/KVY-9550-2024; Yang, Jung/R-7806-2019; LEE, JIN/Q-3108-2018; Ryu, Jeong Yeop/GLQ-9419-2022; PARK, JUN-YOUNG/P-5981-2015 | 58533878200; 57205401706; 56366349400; 57203745682; 55171704700; 7404007181; 55662871100; 57279815300; 37079213100; 56564377200; 56496041000 | leejspo@knu.ac.kr; | GLAND SURGERY | GLAND SURG | 2227-684X | 2227-8575 | 12 | 7 | SCIE | SURGERY | 2023 | 1.5 | 52.6 | 0.98 | 2025-06-25 | 3 | 3 | Boomerang latissimus dorsi (bLD) flap; latissimus dorsi (LD) flap; breast reconstruction; total mastectomy (TM) | MYOCUTANEOUS FLAP; IMPLANT | Boomerang latissimus dorsi (bLD) flap; breast reconstruction; latissimus dorsi (LD) flap; total mastectomy (TM) | English | 2023 | 2023-07 | 10.21037/gs-22-664 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Catastrophic rhabdomyolysis following breast reconstruction operation using an abdominal flap: a case report | Background: Rhabdomyolysis is a potentially fatal clinical syndrome resulting from the damage or breakdown of skeletal muscle, which can also lead to permanent disabilities. Based on our review of studies on rhabdomyolysis after prolonged surgeries, no other cases of rhabdomyolysis caused by muscle injury in the buttock area following breast reconstruction have been reported, making the current report the first to share information related to patient conditions and treatment progress in such cases.Case Description: Here, we present the case of a 57-year-old Asian patient with left breast cancer. We performed immediate breast reconstruction using a deep inferior epigastric perforator (DIEP) flap anastomosed to the internal mammary vessels after a skin-sparing mastectomy with sentinel lymph node biopsy. The surgery exceeded the estimated time because, after anastomosis, severe congestion was observed in the flap and because of the need to perform re-anastomosis and the reconstruction of the internal mammary vein twice. The surgical team eventually re-performed the breast reconstruction using a contralateral pedicled transverse rectus abdominis myocutaneous (TRAM) flap. The patient underwent breast reconstruction in a sitting position to ensure a symmetrical and natural breast shape resembling its original state. Additionally, a brown splint was placed underneath both legs to keep the hip and knees flexed to ensure donor-site closure when using an abdominal-based flap The Patient was closely monitored in the early postoperative period. On postoperative day (POD) 3, patient developed hypotension and was deemed to have experienced a hypovolemic shock. A complete laboratory workup was performed, and a rhabdomyolysis diagnosis was made based on the laboratory results. We believe that rhabdomyolysis resulted from prolonged pressure on the large gluteus maximus muscle located below the site of the pressure sore in the present patient.Conclusions: Postoperative rhabdomyolysis often results from prolonged surgery. Given the possibility of prolonged procedure time in patients undergoing breast reconstruction, the current case emphasizes the need to identify each patient's risk factors for rhabdomyolysis and prepare for possible rhabdomyolysis to prevent ischemic injuries and reduce the risk of complications such as hypovolemic shock. | Kang, Myeong Jae; Cho, Hyun Geun; Lim, Jeong-Hoon; Byun, Sung-Hye; Lee, Su-Hyun; Kang, Byeongju; Lee, Jeeyeon; Park, Ho Yong; Ryu, Jeong Yeop; Choi, Kang Young; Yang, Jung Dug; Chung, Ho Yun; Cho, Byung Chae; Lee, Joon Seok | Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Div Nephrol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Anesthesiol & Pain Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Surg, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Chilgok Hosp, Sch Med, Dept Plast & Reconstruct Surg, 807 Hoguk Ro, Daegu 41404, South Korea | LEE, JIN/Q-3108-2018; Ryu, Jeong Yeop/GLQ-9419-2022; Yang, Jung/R-7806-2019; Lee, Su-Hyun/AAC-7506-2020; Byun, Sung Hye/AEK-1234-2022; Lee, Jong-Mok/KVY-9550-2024; PARK, JUN-YOUNG/P-5981-2015 | 57445997600; 57211205767; 55360244300; 56921446300; 58535842300; 57279815300; 37079213100; 56564377200; 56366349400; 57203745682; 55171704700; 7404007181; 55662871100; 56496041000 | leejspo@knu.ac.kr; | GLAND SURGERY | GLAND SURG | 2227-684X | 2227-8575 | 12 | 7 | SCIE | SURGERY | 2023 | 1.5 | 52.6 | 0 | 2025-06-25 | 0 | 0 | Rhabdomyolysis; breast reconstruction; abdominal flap; breast cancer; case report | BARIATRIC SURGERY; RENAL-FAILURE | abdominal flap; breast cancer; breast reconstruction; case report; Rhabdomyolysis | English | 2023 | 2023-07 | 10.21037/gs-23-8 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Machine learning for high-resolution landslide susceptibility mapping: case study in Inje County, South Korea | Landslides are a major natural hazard that can significantly damage infrastructure and cause loss of life. In South Korea, the current landslide susceptibility mapping (LSM) approach is mainly based on statistical techniques (logistic regression (LR) analysis). According to previous studies, this method has achieved an accuracy of approximately 75.2%. In this paper, we expand upon this traditional approach by comparing the performance of six machine learning (ML) algorithms for LSM in Inje County, South Korea. The study employed a combination of geographical data gathered from 2005 to 2019 to train and evaluate six algorithms, including LR, Gaussian Naive Bayes (GNB), Support Vector Machine (SVM), K-Nearest Neighbors (KNN), Random Forest (RF), and Extreme Gradient Boosting (XGB). The effectiveness of these models was measured by various criteria, such as the percentage of correct classification (PCC) score, F1 score, and Kappa score. The results demonstrated that the PCC and F1 scores of the six models fell between [0.869-0.941] and [0.857-0.940], respectively. RF and XGB had the highest PCC and F1 scores of 0.939 and 0.941, respectively. This study indicates that ML can be a valuable technique for high-resolution LSM in South Korea instead of the current approach. | Le, Xuan-Hien; Eu, Song; Choi, Chanul; Nguyen, Duc Hai; Yeon, Minho; Lee, Giha | Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, Sangju, South Korea; Thuyloi Univ, Fac Water Resources Engn, Hanoi, Vietnam; Natl Inst Forest Sci, Dept Forest Environm & Conservat, Seoul, South Korea | Nguyen, Hai/AAD-8210-2020; Le, Xuan-Hien/AAZ-9166-2021 | 57209735659; 57194056930; 58613779200; 57215097506; 57223436971; 35069799400 | leegiha@knu.ac.kr; | FRONTIERS IN EARTH SCIENCE | FRONT EARTH SC-SWITZ | 2296-6463 | 11 | SCIE | GEOSCIENCES, MULTIDISCIPLINARY | 2023 | 2 | 52.6 | 1.05 | 2025-06-25 | 7 | 7 | disaster management; extreme gradient boosting (XGB); feature importance; landslide; landslide probability; landslide susceptibility mapping (LSM); random forest (RF); risk map | LOGISTIC-REGRESSION; GIS | disaster management; extreme gradient boosting (XGB); feature importance; landslide; landslide probability; landslide susceptibility mapping (LSM); random forest (RF); risk map | Inje; Kangwon; South Korea; disaster management; extreme event; landslide; machine learning; mapping method; natural hazard | English | 2023 | 2023-09-20 | 10.3389/feart.2023.1268501 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effect of void formation according to resin content on composite joint area | The field of application of Glass Fiber Reinforced Polymer expands as well as the size of the component where composite material is applied. Due to the size limitation of the prepreg used, it is difficult to apply 1ply to large parts. Many studies have been reported on the bolt joint that assembles parts and parts for the joint area, butt and overlap design for joining dissimilar materials, and mechanical properties. Although the mechanical properties of the joint areas are important, studies on the microstructure are also needed. In this study, the microstructure was observed by controlling the type of subsidiary materials in the bagging process by applying prepregs of the same composition. It was found that the air and resin flow inside the prepreg acted differently depending on the type of subsidiary material. The flow of resin during curing was inferred from the influence of subsidiary materials and explained by connecting it with the microstructure. The behavior of the resin determined thickness, resin, and void contents of the composite. This flow affects voids in the joint area, causing differences in microstructure and mechanical properties. There was no significant difference in the tensile strength of the laminate specimens manufactured according to the process, but the minimum strength was found in the specimens containing many void contents. The joint specimen showed a decrease in strength as the void content increased. It was discussed that this reduced the adhesive force of the specimen due to the effect of the void generated in the joint area. | Kim, Dong-Chul; Choi, Jeoung Sik; Shin, Hyo-Soon; Jung, InKyun; Heo, Young-Woo | Korea Inst Ceram Engn & Technol, Emerging Mat R&D Div, Jinju, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu, South Korea; Korea Aerosp Ind Ltd, Air Vehicle Anal Dept, Sacheon, South Korea; Korea Inst Ceram Engn & Technol, Emerging Mat R&D Div, Jinju 52851, South Korea | 57226389154; 57478171200; 35273922400; 57969038800; 7004298542 | hshin@kicet.re.kr; | JOURNAL OF COMPOSITE MATERIALS | J COMPOS MATER | 0021-9983 | 1530-793X | 57 | 8 | SCIE | MATERIALS SCIENCE, COMPOSITES | 2023 | 2.3 | 52.9 | 0 | 2025-06-25 | 0 | 0 | GFRP composite; resin content; prepreg joint area; subsidiary material; mechanical properties | MECHANICAL-PROPERTIES; BEHAVIOR; GLASS; PERFORMANCE; FABRICATION; STRENGTH; CURE | GFRP composite; mechanical properties; prepreg joint area; resin content; subsidiary material | Adhesives; Bolted joints; Dissimilar materials; Fiber reinforced plastics; Resins; Tensile strength; Composite joint; Effect of voids; GFRP composites; Joint area; Prepreg joint area; Prepregs; Resin content; Subsidiary material; Void contents; Voids formation; Microstructure | English | 2023 | 2023-04 | 10.1177/00219983231157275 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Silicon Graphite Composite Anode Degradation: Effects of Silicon Ratio, Current Density, and Temperature | Recently, a graphite-silicone (GrSi) composite anode has attracted a lot of attention due to its enhanced capacity and stability over pure Si anode. Herein, the abnormal behaviors and the degradation of the composite electrode during the repeated charging/discharging cycles are investigated. At each cycle, the capacity retention, Coulombic efficiency, irreversible, and differential capacity are analyzed to examine the contribution of each Gr and Si on the capacity. Generally, the composite electrodes are found to show a rapid initial decrease in capacity as the silicon ratio increases, indicating that silicone is the major contributor of the initial drop. Also, the capacity contribution of the graphite can also decrease rapidly for some conditions such as low temperature and high rate due to higher charge transfer resistance of the graphite. Interestingly, at certain conditions, the capacity decreases initially and recovers; differential capacity analysis revealed that this was due to the initial loss and recovery of graphite reactions. The degree of recovery decreased with increasing Si partly due to the higher resistivity of Si. Our findings could be useful for designing and operating composite electrodes with higher performance and stability. | Choi, Jongeun; Kim, Giyong; Kim, Sung Yeol | Kyungpook Natl Univ, Dept Mech Engn, Daegu 41566, South Korea | Kim, Sung Yeol/D-1412-2013; kim, sung/D-1412-2013 | 58398330000; 57354461700; 19337822900 | sykimknu@knu.ac.kr; | ENERGY TECHNOLOGY | ENERGY TECHNOL-GER | 2194-4288 | 2194-4296 | 11 | 9 | SCIE | ENERGY & FUELS | 2023 | 3.6 | 52.9 | 0.57 | 2025-06-25 | 6 | 6 | composites; degradation; differential capacity analysis; graphite; silicon | IN-SITU OBSERVATION; LI-ION BATTERIES; HIGH-CAPACITY; LITHIUM; PERFORMANCE; ELECTRODES; DISCHARGE; DENDRITE; FAILURE | composites; degradation; differential capacity analysis; graphite; silicon | Anodes; Charge transfer; Graphite; Silicones; Temperature; Abnormal behavior; Charging/discharging; Composite anodes; Composites electrodes; Condition; Degradation effect; Differential capacity analysis; Si anodes; Silicon/graphite composites; Silicone composites; Silicon | English | 2023 | 2023-09 | 10.1002/ente.202201444 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Application of isothermal chemical denaturation to early-stage formulation development of fibrinogen | The purpose of this study was to develop fibrinogen formulation using isothermal chemical denaturation (ICD), which is a technique that measures the conformational stability of proteins through structure perturbation by denaturants such as urea. Fibrinogen has been used to treat various congenital and acquired human fibrinogen-related disorders that represent a group of rare conditions. In this study, 10 formulations of fibrinogen were initially prepared and appropriate formulations were screened via automated, high-throughput ICD measurements. The optimal formulation selection process was further performed through osmolality measurements and accelerated stability study at 40 degrees C and 75% relative humidity. The fibrinogen formulation was optimized with 20 mg/ml fibrinogen, 16 mg/ml L-arginine, 10 mg/ml glycine, 1.2 mg/ml tri-sodium citrate dihydrate, and 3.5 mg/ml sodium chloride at pH 7.0. This study demonstrates that ICD-based formulation screening approach is highly applicable to early-stage formulation development of fibrinogen. | Son, Jae Woon; Son, Jong Mun; Hur, Ki Ho; Lee, Wonhwa; Song, Im-Sook; Na, Dong Hee | GC Biopharm, Yongin, South Korea; Kyungpook Natl Univ, Coll Pharm, Daegu, South Korea; Chung Ang Univ, Coll Pharm, Seoul, South Korea; Chungbuk Natl Univ, Coll Pharm, Cheongju, South Korea; Sungkyunkwan Univ, Dept Chem, Suwon, South Korea; Chung Ang Univ, Coll Pharm, Seoul 06974, South Korea; Kyungpook Natl Univ, Coll Pharm, Daegu 41566, South Korea | ; Lee, Wonhwa/GLQ-6506-2022; Son, Jaewoon/MYR-9255-2025 | 57375439100; 58038063100; 58037683400; 50161632800; 7201564500; 7103210503 | songimsook1@gmail.com;dhna@cau.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 44 | 4 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2023 | 2.3 | 53.0 | 0.09 | 2025-06-25 | 1 | 1 | fibrinogen; high-throughput screening; isothermal chemical denaturation; protein formulation; stability | STABILITY; TOOL; ARGININE; GLYCINE | fibrinogen; high-throughput screening; isothermal chemical denaturation; protein formulation; stability | Amino acids; Chemical stability; Denaturation; Isotherms; Proteins; Sodium chloride; Chemical denaturation; Condition; Conformational stabilities; Fibrinogen; Formulation development; High throughput screening; High-throughput; Isothermal chemical denaturation; Optimal formulation; Protein formulation; Urea | English | 2023 | 2023-04 | 10.1002/bkcs.12664 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Carbon-based organic radical spin filters | Single-molecule magnetic junctions serve as an important component for the manipulation of spin-polarized currents by chemical modifications and control of magnetic interactions in spintronic devices. We employed the nonequilibrium green function and spin-polarized density functional theory simulations to investigate the performance of molecular junctions bearing an organic radical as spin filters. A spin-polarized current could be generated using the junctions and, moreover, the spin-filtering efficiency could be tuned by varying the number of magnetic units. Spin orbital and density of states analyses revealed the relationship effect of the shapes and energy levels of the dominant electron-conducting channels in the spin-filtering efficiency. Thus, the use of a tunable organic magnetic molecular junction system is an appealing approach for regulating spin-polarized currents in spintronic devices. | Cho, Daeheum | Kyungpook Natl Univ, Dept Chem, Daegu, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | Cho, Daeheum/D-9235-2018 | 55263218400 | daeheumc@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 44 | 8 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2023 | 2.3 | 53.0 | 0.09 | 2025-06-25 | 1 | 1 | molecular junction; organic magnetic molecules; spin filter; spin transport; spintronics | ELECTRON-TRANSPORT; POLYRADICALS; DIRADICALS | molecular junction; organic magnetic molecules; spin filter; spin transport; spintronics | Carbon; Density functional theory; Molecules; Organic carbon; Spin polarization; Spintronics; Magnetic molecules; Molecular junction; Organic magnetic molecule; Organic radicals; Organics; Spin filtering; Spin filters; Spin transport; Spin-polarized currents; Spintronics device; Chemical modification | English | 2023 | 2023-08 | 10.1002/bkcs.12716 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | Article | Effectiveness of Switching to Long-acting Injectable Aripiprazole in Patients with Recent-onset and Chronic Schizophrenia | Objective: This study investigated the effectiveness of switching to once-monthly long-acting injectable (LAI) aripiprazole from other second-generation antipsychotics including LAI paliperidone palmitate in both recent-onset and chronic schizophrenia patients. Methods: This was a 24-week prospective, open-label, flexible dose-switching study in patients with schizophrenia. Scores on the Positive and Negative Syndrome Scale (PANSS), Personal and Social Performance (PSP) scale, Clinical Global Impression (CGI), Subjective Well-being Under Neuroleptics−Short Form (SWN-K), and a computerized emotional recognition test (ERT) were evaluated. Subjects were divided into two groups (recent onset and chronic) based on 5 years' duration of the illness. Results: Among the 82 patients participating, 67 (81.7%) completed the 24-week study. The discontinuation rate after switching to LAI aripiprazole did not differ according to clinical characteristics including type of previous antipsychotics. Scores on the PANSS, PSP, SWN-K, CGI, and ERT were significantly improved after a switch to LAI aripiprazole without exacerbation of metabolic parameters and bodyweight. The improvements in the PANSS, PSP, and CGI scores were significantly greater in patients with recent-onset than in those with chronic schizophrenia; the improvement in metabolic parameters was significantly greater in the latter group. Conclusion: High rates of successful switching to LAI aripiprazole from other antipsychotics suggest its good tolerability and effectiveness. Improvements in psychopathology and social functioning were more evident in patients with recent-onset schizophrenia, and improvements in metabolic abnormalities were more prominent in patients with chronic schizophrenia.

| ○ | ○ | Article | Facile production of graphene quantum dots using a molecular adhesive membrane filter | Despite the myriad of studies on graphene quantum dots (GQDs), the commercialization of GQDs has been extremely limited until recently. The biggest bottleneck is the absence of a method for the mass production of GQDs. In this paper, we report a facile method for separating GQDs from chemically modified graphene suspensions using a filter paper embedded with polydopamine nanoparticles. The polydopamine nanoparticles, which have excellent molecular adhesion, interact more preferably with graphene oxide (GO) than with GQDs owing to the larger size of GO particles and high ratio of oxygenated functional groups in GO. We analyze the electron diffraction patterns, photoluminescence properties, and diameter/height profiles of the collected GQDs and conclude that the proposed separation technique yields high-purity GQDs. We believe that this technology can revolutionize the GQD field and relevant applications in fuel cells, semiconductors, bioimaging, and biosensing. | Kim, Yuejin; Min, Kyoung-Ik; Jeong, Sanghwa; Lee, Kyueui | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu, South Korea; Kyungpook Natl Univ, Biomed Convergence Sci & Technol, Daegu 41566, South Korea; Pusan Natl Univ, Sch Biomed Convergence Engn, Yangsan 50612, South Korea | Lee, Kyueui/P-8152-2018; Lee, Kyueui/ACR-8902-2022 | 57966884600; 25028141900; 55550619600; 56404800600 | minwing8055@knu.ac.kr;sanghwa.jeong@pusan.ac.kr;kyueui@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 44 | 2 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2023 | 2.3 | 53.0 | 0.55 | 2025-06-25 | 5 | 6 | biomimetics; graphene oxide; graphene quantum dot; mussel-inspired chemistry; polydopamine | POLYDOPAMINE; ENHANCEMENT; CHEMISTRY | biomimetics; graphene oxide; graphene quantum dot; mussel-inspired chemistry; polydopamine | Adhesives; Biomimetics; Carbon Quantum Dots; Fuel cells; Graphene; Graphene quantum dots; Nanocrystals; Particle size analysis; Chemically-modified graphene; Commercialisation; Facile method; Facile production; Graphene oxides; Inspired chemistries; Mass production; Membrane filters; Mussel-inspired chemistry; Polydopamine; Semiconductor quantum dots | English | 2023 | 2023-02 | 10.1002/bkcs.12644 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
