| ○ | ○ | Article | Strategic Use of Extremophilic Microalgae as a Carbon Source in the Thermo-Chemical Process | Microalgal biomass has a high CO2 fixation and growth rate when using CO2 as a carbon source. Moreover, biomass can also be employed as a carbon resource to produce biofuels and chemicals. As the growth rate of extremophilic microalgae remains unaffected by harsh conditions, the present study proposes that these microalgae (such as Galdieria sulphuraria) are a rapidly growing carbon resource for syngas production. Hence, two different experiments were performed as part of this study: (1) cultivation of G. sulphuraria under outdoor conditions and (2) conversion of G. sulphuraria into syngas. The productivity of G. sulphuraria under mixotrophic condition (0.82 g L-1 d-1) was about 1.6 faster than a widely cultivated Chlorella sp. HS2. Moreover, G. sulphuraria was converted into syngas using CO2 as a co-feedstock. The simultaneous reduction of CO2 and the oxidation of volatile matter (VM) from the thermolysis of G. sulphuraria promoted syngas formation. The chemical reaction was influenced by the molecular size of the VMs. In the presence of the Ni catalyst, low-molecular-weight VMs were formed owing to chemical bond scissions. Syngas formation under CO2 doubled compared with that under inert conditions. The findings suggest that G. sulphuraria is a feasible carbon source for CO2 fixation and chemical production. | Choi, Dongho; Kwon, Dohee; Lee, Doyeon; Jung, Sungyup; Chen, Wei-Hsin; Lim, Jin-Kyu; Park, Seong-Jik; Park, Won-Kun; Kwon, Eilhann E. | Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Hanbat Natl Univ, Dept Civil & Environm Engn, Daejeon 34158, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Natl Cheng Kung Univ, Dept Aeronaut & Astronaut, Tainan 701, Taiwan; Tunghai Univ, Res Ctr Smart Sustainable Circular Econ, Taichung 407, Taiwan; Natl Chin Yi Univ Technol, Dept Mech Engn, Taichung 411, Taiwan; Sangmyung Univ, Dept Chem & Energy Engn, Seoul 03016, South Korea; Hankyong Natl Univ, Dept Bioresources & Rural Syst Engn, Anseong 17579, South Korea | ; Jung, Sungyup/ABE-1493-2021; Park, Seong-Jik/JDN-3009-2023; Chen, Wei-Hsin/S-2033-2018; Kwon, Eilhann/AGY-3339-2022; Choi, Dongho/LTY-8225-2024 | 57200013497; 57208275497; 55881252900; 55073290800; 57200873137; 58186719500; 34668330800; 57780193700; 9240622100 | wkpark@smu.ac.kr;ek2148@hanyang.ac.kr; | ACS SUSTAINABLE CHEMISTRY & ENGINEERING | ACS SUSTAIN CHEM ENG | 2168-0485 | 11 | 16 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, CHEMICAL;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2023 | 7.1 | 12.1 | 0.45 | 2025-06-25 | 5 | 5 | carbon neutrality; circular economy; CO2 utilization; extremophilic microalgae; thermo-chemical process; syngas | CATALYTIC PYROLYSIS; METHYL-ESTERS; CO2; DIGESTION; PROTEINS; BIOCHAR; ENERGY; WASTE; OIL | carbon neutrality; circular economy; CO<sub>2</sub> utilization; extremophilic microalgae; syngas; thermo-chemical process | Carbon; Carbon dioxide; Cultivation; Growth rate; Microorganisms; Synthesis gas; A-carbon; Carbon neutralities; Carbon source; Circular economy; CO2 utilization; Condition; Extremophilic microalga; Micro-algae; Syn gas; Thermo chemical process; Microalgae | English | 2023 | 2023-04-24 | 10.1021/acssuschemeng.3c00486 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Superior capsular reconstruction using hybrid graft for irreparable massive rotator cuff tear | PurposeTo evaluate the clinical and radiological outcomes of arthroscopic superior capsular reconstruction (SCR) using hybrid grafts composed of tensor fascia lata autografts and human dermal allografts.MethodsThis study included 30 patients with chronic irreparable posterosuperior rotator cuff tears (RCTs) who underwent arthroscopic SCR using a hybrid graft composed of tensor fascia lata autograft and human dermal allograft. Clinical outcomes were evaluated using the pain visual analogue scale score, shoulder range of motion, American Shoulder and Elbow Surgeons score, constant score, University of California-Los Angeles score, and simple shoulder test score preoperatively and at least 2 years after surgery. Radiographic analysis included the Hamada classification grade, acromiohumeral distance (AHD), and graft integrity at 2 years after surgery.ResultsAll patients exhibited significant clinical improvement in all functional outcome measurements, except external rotation (all P < 0.05). The number of patients who exhibited pseudoparalysis decreased from 7 (23.3%) to 2 (6.7%) postoperatively. Complications were not observed. Radiologically, the mean postoperative AHD increased significantly from 6.9 +/- 1.6 cm to 8.8 +/- 2.1 cm at 2 years postoperatively (P < 0.001). Twenty five out of the 30 (83.3%) patients showed successful graft healing, and all healing failures occurred on the humeral side. The differences between the healed-graft and failed-graft groups were significantly lower graft thickness (P = 0.001) and smaller AHD (P < 0.001) in the failed-graft group. Every functional outcome scores were not statistically different between healed-graft and failed-graft groups.ConclusionsAn arthroscopic SCR technique using a hybrid graft consisting of a tensor fascia lata autograft and human dermal allograft showed satisfactory clinical outcomes in patients with irreparable RCTs. | Yoon, Jong Pil; Kim, Dong-Hyun; Yoon, Jee wook; Jung, Youngsoo; Park, Kyeong Hyeon; Lee, Jihwan; Chung, Seok Won | Kyungpook Natl Univ, Sch Med, Dept Orthoped Surg, Daegu, South Korea; Konkuk Univ, Ctr Shoulder & Elbow Surg, Sch Med, Dept Orthopaed Surg, 120-1 Neungdong Ro Hwayang Dong, Seoul 143729, South Korea | Park, KyeongHyeon/KEH-4919-2024 | 36098548400; 57198637188; 57188967905; 58080434900; 56969984400; 57202007254; 37065938600 | smilecsw@gmail.com; | KNEE SURGERY SPORTS TRAUMATOLOGY ARTHROSCOPY | KNEE SURG SPORT TR A | 0942-2056 | 1433-7347 | 31 | 7 | SCIE | ORTHOPEDICS;SPORT SCIENCES;SURGERY | 2023 | 3.3 | 12.1 | 1.45 | 2025-06-25 | 4 | 5 | Superior capsular reconstruction; Hybrid graft; Tensor fascia lata; Human dermal allograft; Irreparable massive rotator cuff tear | CRUCIATE LIGAMENT RECONSTRUCTION; DERMAL ALLOGRAFT; SHOULDER STIFFNESS; FATTY DEGENERATION; REPAIR; TENDON; SUPRASPINATUS; OUTCOMES; STABILITY; THICKNESS | Human dermal allograft; Hybrid graft; Irreparable massive rotator cuff tear; Superior capsular reconstruction; Tensor fascia lata | Arthroscopy; Humans; Range of Motion, Articular; Rotator Cuff Injuries; Shoulder Joint; Transplantation, Autologous; Transplantation, Homologous; Treatment Outcome; allotransplantation; arthroscopy; autotransplantation; human; procedures; range of motion; rotator cuff injury; shoulder joint; treatment outcome | English | 2023 | 2023-07 | 10.1007/s00167-023-07321-2 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Review | The Diagnostic Value of ¹⁸F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in Differentiated Thyroid Cancer Patients with Elevated Thyroglobulin/Thyroglobulin Antibody Levels and Negative Iodine Scintigraphy: A Systematic Review and Meta-Analysis | Background: The objective of this study is to evaluate the diagnostic accuracy of F-18-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) in detecting recurrence in patients with differentiated thyroid cancer (DTC) who have negative whole-body scans (WBSs) but elevated serum thyroglobulin (Tg) or thyroglobulin antibody (TgAb) levels.Methods: This systematic review/meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis for Diagnostic Test Accuracy criteria (International Prospective Register of Systematic Reviews registration number: CRD42022340924). A comprehensive search of the MEDLINE, EMBASE, and Cochrane databases identified articles reporting the diagnostic accuracy of FDG PET/CT for the detection of recurrence in patients with DTC with negative WBS and elevated serum Tg or TgAb levels published between January 2012 and June 2023. Meta-analyses were performed to determine the diagnostic accuracy of FDG PET/CT on the total target population as well as on subgroups stratified by serum Tg or TgAb, and thyrotropin (TSH) stimulation status at the time of FDG PET/CT. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework was applied to evaluate the quality of evidence and the strength of recommendations to facilitate translation of the meta-analysis results into practical recommendations for clinical guidelines.Results: A total of 24 studies involving 1988 patients were included for analysis. The overall pooled sensitivity and specificity values were 0.87 (95% confidence interval [CI] = 0.83-0.92; I-2 = 75%) and 0.84 (CI = 0.80-0.89; I-2 = 44%), respectively. Subgroup analyses revealed no significant differences in the diagnostic accuracy of FDG PET/CT in patients stratified by serum Tg or TgAb levels, and TSH stimulation status at the time of PET/CT. Treatment plans were changed following FDG PET/CT imaging in 40% (CI = 34-47%; I-2 = 39%) of cases. The quality level of evidence for using FDG PET/CT was moderate in both sensitivity and specificity according to the GRADE system.Conclusion: There is moderate quality evidence demonstrating the high diagnostic accuracy of FDG PET/CT in detecting recurrence in patients with DTC with negative WBS and elevated serum Tg or TgAb levels. This evidence corroborates the current guidelines' endorsement of FDG PET/CT as a diagnostic tool in such patients. | Bang, Ji-In; Park, Sohyun; Kim, Keunyong; Seo, Youngduk; Chong, Ari; Hong, Chae Moon; Choi, Miyoung; Lee, Sang-Woo; Oh, So Won | CHA Univ, CHA Bundang Med Ctr, Dept Nucl Med, Gyeonggi Do, South Korea; Natl Canc Ctr Res Inst & Hosp, Dept Nucl Med, Gyeonggi Do, South Korea; Pusan Natl Univ, Pusan Natl Univ Hosp, Dept Nucl Med, Pusan, South Korea; Pusan Natl Univ, Pusan Natl Univ Hosp, Biomed Res Inst, Pusan, South Korea; Pusan Natl Univ, Sch Med, Pusan, South Korea; Chungnam Natl Univ, Sejong Hosp, Dept Nucl Med, Sejong, South Korea; Chosun Univ, Sch Med, Dept Nucl Med, Gwangju, South Korea; Kyungpook Natl Univ, Sch Med, Dept Nucl Med, Daegu, South Korea; Natl Evidence Based Healthcare Collaborating Agcy, Div Healthcare Technol Assessment Res, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Nucl Med, Daegu, South Korea; Chilgok Hosp, Daegu, South Korea; Seoul Natl Univ, Boramae Med Ctr, Dept Nucl Med, 20 Boramae Ro 5 Gil, Seoul 07061, South Korea | Choi, Miyoung/HZH-8501-2023; lee, sangwoo/KUD-1906-2024 | 56504705800; 56870601600; 36523010700; 57202988600; 26533830900; 37050876700; 57129603200; 57196249819; 36154944900 | mdosw@snu.ac.kr; | THYROID | THYROID | 1050-7256 | 1557-9077 | 33 | 10 | SCIE | ENDOCRINOLOGY & METABOLISM | 2023 | 6 | 12.1 | 1.8 | 2025-06-25 | 11 | 10 | F-18-fluorodeoxyglucose; meta-analysis; positron emission tomography/computed tomography; thyroglobulin; thyroid cancer | WHOLE-BODY SCAN; HIGH SERUM THYROGLOBULIN; F-18 FDG PET/CT; TERM-FOLLOW-UP; ANTITHYROGLOBULIN ANTIBODY; CARCINOMA PATIENTS; TEST ACCURACY; RECURRENCE; PAPILLARY; F-18-FDG-PET | Adenocarcinoma; Fluorodeoxyglucose F18; Humans; Iodine; Iodine Radioisotopes; Positron Emission Tomography Computed Tomography; Positron-Emission Tomography; Thyroglobulin; Thyroid Neoplasms; Thyrotropin; fluorodeoxyglucose f 18; iodine; thyroglobulin; thyroglobulin antibody; thyrotropin; fluorodeoxyglucose f 18; radioactive iodine; thyroglobulin; thyrotropin; adult; aged; antibody blood level; Article; bone metastasis; cancer diagnosis; cancer patient; cancer recurrence; diagnostic accuracy; diagnostic value; differentiated thyroid cancer; distant metastasis; female; GRADE approach; histopathology; human; intermethod comparison; local metastasis; lung metastasis; lymph node metastasis; male; mediastinum lymph node; meta analysis; middle aged; nuclear magnetic resonance imaging; poorly differentiated thyroid cancer; positron emission tomography-computed tomography; receiver operating characteristic; regional metastasis; sensitivity and specificity; systematic review; thyroglobulin blood level; thyroid follicular carcinoma; thyroid papillary carcinoma; thyroid scintiscanning; thyrotropin blood level; whole body scintiscanning; adenocarcinoma; positron emission tomography; positron emission tomography-computed tomography; thyroid tumor | English | 2023 | 2023-10-01 | 10.1089/thy.2023.0264 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Types and doses of anti-adhesive agents injected into subacromial space do not have an effect on the clinical and anatomical outcomes after arthroscopic rotator cuff repair | PurposeJoint stiffness after arthroscopic rotator cuff repair is a major concern for orthopaedic surgeons. Various antiadhesive agents are commonly administered after rotator cuff repair for its prevention. This study aimed to compare the outcomes among patients injected with different types and amounts of anti-adhesive agents after rotator cuff repair. It was hypothesized that the outcomes might differ depending on the use of the anti-adhesive agent and its type and dose.MethodsA total of 267 patients who underwent arthroscopic rotator cuff repair with or without subacromial injection of anti-adhesive agents were enrolled. The first group (group A; 51 patients) were injected with 3 mL of poloxamer/sodium alginate-based anti-adhesive agent. The second group (group B; 93 patients) were injected with 3 mL of sodium hyaluronate-based anti-adhesive agent. The third group (group C; 82 patients) were injected with 1.5 mL of sodium hyaluronate-based anti-adhesive agent. Finally, the last group (group D; 41 patients) who did not use anti-adhesive agents served as the control. The range of motion (ROM) and pain VAS scores were measured preoperatively and at 5 weeks, 3 months, 6 months, and 1 year postoperatively. Functional outcomes were evaluated using American Shoulder and Elbow Surgeons and Constant scores, whereas cuff integrity was assessed via MRI or ultrasonography at least 6 months postoperatively.ResultsAll ROM measurements, pain VAS scores, and functional scores were significantly improved regardless of the use, type, and dose of the anti-adhesive agents. In addition shoulder ROM and rotator cuff healing did not significantly differ among the groups (all n.s.).ConclusionsNo significant differences were found in the clinical and anatomical outcomes according to the type and dose of the anti-adhesive agents subacromially injected after rotator cuff repair. | Lee, Jongwon; Yoon, Jong Pil; Woo, Youngje; Oh, Kyung-Soo; Chung, Seok Won | Konkuk Univ, Ctr Shoulder & Elbow Surg, Sch Med, Dept Orthopaed Surg, 120-1 Neungdong Ro Hwayang Dong, Seoul 143729, South Korea; Kyungpook Natl Univ, Sch Med, Dept Orthopaed Surg, Daegu, South Korea | 57192108991; 36098548400; 58541814700; 57693386500; 37065938600 | smilecsw@gmail.com; | KNEE SURGERY SPORTS TRAUMATOLOGY ARTHROSCOPY | KNEE SURG SPORT TR A | 0942-2056 | 1433-7347 | 31 | 11 | SCIE | ORTHOPEDICS;SPORT SCIENCES;SURGERY | 2023 | 3.3 | 12.1 | 0.29 | 2025-06-25 | 1 | 1 | Rotator cuff repair; Anti-adhesive agent; Poloxamer; sodium alginate; Sodium hyaluronate | TEARS; DEGENERATION; ULTRASOUND; STIFFNESS; ADHESION; SURGERY | Anti-adhesive agent; Poloxamer/sodium alginate; Rotator cuff repair; Sodium hyaluronate | English | 2023 | 2023-11 | 10.1007/s00167-023-07519-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | A multifunctional network binder enables stable and high performance of silicon-based anode in lithium-ion battery | Rechargeable lithium-ion batteries with high energy density have attracted attention as a means of solving environmental problems. Silicon (Si) has been considered as one of the most promising anode materials due to its high theoretical capacity of 3579 mAh g-1 (Li15Si4). However, the enormous volume change of Si occurs during lithiation/delithiation process, which seriously deteriorates the mechanical/electrochemical stability of Si anodes. To address these inherent problems, it is of importance to develop a functional binder capable of reducing the volume variation of Si anodes. In this work, we first design a new binder system by employing a Multifunctional Network Binder (MNB) to synergistically improve the electrochemical stability and performances of Si-based electrodes. The introduction of MNB into the Li-PAA-based electrode system constructs a strong binding matrix through abundant functional bridges. In addition, the MNB with high dispersion stability improves the ionic conductivity of Si-based electrodes. Owing to these synergistic effects of Li-PAA/MNB binder system, the volume expansion of Si-based electrodes was significantly suppressed, contributing to the excellent Coulombic efficiency (99.9%) and capacity retention (87% after 100 cycles). | Park, Hyunjung; Han, Seungmin; Tak, Heetae; Kim, Junghwan; Roh, Kwangchul; Jung, Dae Soo; Song, Taeseup; Kim, Patrick Joohyun; Choi, Junghyun | Chosun Univ, Dept Mat Sci & Engn, Gwangju 61452, South Korea; Korea Inst Ceram Engn & Technol, Energy Storage Mat Ctr, Jinju 52851, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Hanyang Univ, Dept Energy Engn, Seoul 133791, South Korea | Hahn, Seung min/MBH-8374-2025 | 55713687300; 58619237900; 58245294600; 55966669500; 35175060800; 16233760500; 25825726200; 57195611779; 59883103900 | tssong@hanyang.ac.kr;pjkim@knu.ac.kr;jchoi@kicet.re.kr; | JOURNAL OF POWER SOURCES | J POWER SOURCES | 0378-7753 | 1873-2755 | 574 | SCIE | CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 8.1 | 12.2 | 1.28 | 2025-06-25 | 12 | 13 | POLYACRYLIC-ACID PAA; RENEWABLE ENERGY; ELECTRODES; GRAPHITE; CAPACITY | Anodes; Electrochemical electrodes; Lithium compounds; Lithium-ion batteries; Silicon batteries; Anode material; Binder systems; Electrochemical stabilities; Environmental problems; Higher energy density; Performance; Rechargeable lithium ion battery; Silicon anode; Silicon-based; Theoretical capacity; Silicon | English | 2023 | 2023-08-01 | 10.1016/j.jpowsour.2023.233159 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Automatic Site Survey for RSS-Based Wi-Fi Positioning Using Unlabeled Data | Preparing a database of Wi-Fi access points (APs) is essential for deploying Wi-Fi-based positioning solutions. This study proposes an automated method to discover APs installed in an indoor site by exploiting unlabeled data provided by mobile users. Furthermore, the positions of these APs are estimated by comparing the shapes of two trajectories, which are obtained using the provided Wi-Fi and sensor data. The effectiveness of the proposed method is verified with excessive experimental campaigns, including an extreme case scenario, where the positions of 60 APs are obtained from only three APs with known positions. | Choi, Jeongsik | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | ; Choi, Jeongsik/ABA-6906-2020 | 58534394200 | jeongsik-choi722@gmail.com;jeongsikchoi722@gmail.com; | IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY | IEEE T VEH TECHNOL | 0018-9545 | 1939-9359 | 72 | 8 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;TRANSPORTATION SCIENCE & TECHNOLOGY | 2023 | 6.1 | 12.2 | 0.26 | 2025-06-25 | 1 | 2 | Indoor positioning; received signal strength; inertial sensors; site survey | Indoor positioning; inertial sensors; received signal strength; site survey | Gyroscopes; Indoor positioning systems; Mobile computing; Wireless local area networks (WLAN); Access points; Automated methods; Indoor positioning; Inertial sensor; Mobile users; Received signal strength; Shape; Site surveys; Unlabeled data; Wireless fidelities; Wi-Fi | English | 2023 | 2023-08 | 10.1109/tvt.2023.3253934 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Caregiving Strain, family functioning, and effort to change diet for patients with gastrointestinal cancer: A cross-sectional descriptive study | Purpose: Among patients with cancer, it has been found that the family system influences health-related be-haviors and may promote a healthy diet. This study assessed the associations among cancer patients between family caregiver strain, family functioning, and efforts to change diet.Methods: This cross-sectional descriptive study was conducted in gastrointestinal outpatient units at two tertiary university hospitals in South Korea. This study included 401 main family caregivers of patients with gastroin-testinal cancer. The caregivers were evaluated using structured, face-to-face questionnaires measuring family strain, family functioning, and effort to change diet.Results: Greater effort to change diet was associated with higher family functioning, having a spouse, and more caregiving time per week. Less effort to change diet was associated with greater levels of caregiving strain and with a son providing caregiving.Conclusion: The efforts of family caregivers to alter diet are influenced by family strain and family functioning, as well as family caregivers' characteristics, such as marital status, health problems due to caregiving, care time and duration, and relationship with the patient. This study suggested that reducing family strain and improving family functioning in clinical settings facilitate the success to change dietary strategies for cancer families. | Lee, Myung Kyung | Kyungpook Natl Univ, Res Inst Nursing Sci, Coll Nursing, Daegu, South Korea; Res Inst Nursing Sci, Coll Nursing, 680 Gukchabosangro, Daegu 41944, South Korea | 40661513200 | mlee@knu.ac.kr; | EUROPEAN JOURNAL OF ONCOLOGY NURSING | EUR J ONCOL NURS | 1462-3889 | 1532-2122 | 62 | SCIE;SSCI | NURSING;ONCOLOGY | 2023 | 2.7 | 12.2 | 1.29 | 2025-06-25 | 6 | 5 | Digestive system; Neoplasms; Diet; Family health; Family Characteristics; Health behavior | ZARIT-BURDEN-INTERVIEW; INFORMAL CAREGIVERS; PHYSICAL-ACTIVITY; SHORT VERSION; INTERVENTIONS; CARE; RELIABILITY; CHILDREN; VALIDITY; HEALTH | Diet; Digestive system; Family Characteristics; Family health; Health behavior; Neoplasms | Caregivers; Cross-Sectional Studies; Diet, Healthy; Family; Gastrointestinal Neoplasms; Humans; Surveys and Questionnaires; caregiver; cross-sectional study; family; gastrointestinal tumor; human; questionnaire | English | 2023 | 2023-02 | 10.1016/j.ejon.2022.102264 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Enhanced lifespan and rate capability of cobalt hexacyanoferrate in aqueous Na-ion batteries owing to particle size reduction | Cobalt hexacyanoferrate (CoHCF) suffers from low rate capability and lifespan because of the dissolution and structural instability of Co during cycling. A smaller active material can relieve the stress caused by volume change during cycling and enable shorter transport pathways. Here, particle size reduction is performed by reducing the mixing time or citrate concentration in the coprecipitation reaction to improve the rate capability and lifespan of CoHCF. The reduced mixing time produces smaller particles with enlarged active sites, thus improving the capacity. Upon coprecipitation at a low citrate concentration, particle precipitation at reduced sizes is achieved by preferential nucleation versus growth. Although lowering the citrate concentration enlarges the external surface area, the reduced redox-active Fe degrades the capacity. All CoHCF samples with small sizes achieved enhance rate capability and stability. In particular, the sample synthesized with a short mixing time (0 h) achieve a specific capacity of 122 mAh g-1 with improved rate capability (79.4%) and stability (79.3%) over 500 cycles. Structural distortions are relaxed because of the shortened transport pathways and relieved distortion owing to particle size reduction. This study paves the approach for fast rechargeable and long-lasting aqueous Na-ion batteries using CoHCF electrodes. | Choi, Young Mook; Kim, Jihwan; Li, Li; Chun, Sang-Eun | Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea; Northeastern Univ, State Key Lab Rolling & Automat, Shenyang 110819, Peoples R China; Northeastern Univ, Sch Met, Shenyang 110819, Peoples R China; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea | Li, Li/ABF-1706-2020 | 57373623200; 58743659700; 56122801700; 36801080300 | lilicmu@alumni.cmu.edu;sangeun@knu.ac.kr; | JOURNAL OF POWER SOURCES | J POWER SOURCES | 0378-7753 | 1873-2755 | 556 | SCIE | CHEMISTRY, PHYSICAL;ELECTROCHEMISTRY;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 8.1 | 12.2 | 1.16 | 2025-06-25 | 10 | 11 | Cobalt hexacyanoferrate; Particle miniaturization; Rate capability; Stability; Structural distortion | PRUSSIAN BLUE ANALOGS; ELECTROCHEMICAL ENERGY-STORAGE; CATHODE MATERIAL; MAGNETIC-PROPERTIES; PROMISING CATHODE; SUPERIOR CATHODE; STABILITY; PERFORMANCE; NANOCUBES; WHITE | Cobalt hexacyanoferrate; Particle miniaturization; Rate capability; Stability; Structural distortion | Cobalt; Coprecipitation; Mixing; Particle size; Redox reactions; Sodium-ion batteries; Cobalt hexacyanoferrate; Lifespans; Miniaturisation; Mixing time; Na-ion batteries; Particle miniaturization; Particle size reduction; Rate capabilities; Structural distortions; Transport pathways; Stability | English | 2023 | 2023-02-01 | 10.1016/j.jpowsour.2022.232407 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | GPS-Aided Automatic Site Survey Method for WiFi RTT-Based Positioning | The fine timing measurement protocol defined in the IEEE 802.11-2016 standard leads to precise ranging between WiFi devices. However, because the locations of WiFi access points (APs) are required for locating mobile devices, a site survey must be performed prior to the deployment of positioning services, which is extremely time-consuming. This article studies an automated site survey method that utilize the global positioning system (GPS) and built-in sensors in mobile devices. When a user enters an indoor site from outside, the outside trajectory is obtained using GPS and built-in sensors, and the indoor trajectory can be estimated solely relying on the sensor measurements. Thereafter, the locations of APs can be determined using the ranging results obtained at multiple positions on the estimated indoor trajectory. The experimental results revealed that the difference in average positioning error obtained using the estimated and perfect AP locations was 30 cm. | Park, Kyoung-Min; Lee, Byeong-ho; Lee, Eunji; Kim, Seong-Cheol; Choi, Jeongsik | Samsung Elect, Samsung Res, Seoul 497001, South Korea; Seoul Natl Univ, Dept Elect Engn, Seoul 08826, South Korea; Seoul Natl Univ, Inst New Media & Commun, Seoul 08826, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 37224, South Korea | ; Choi, Jeongsik/ABA-6906-2020 | 57201318307; 57195528668; 57393526900; 22334016200; 58534394200 | km92.park@samsung.com;byeongho.lee@samsung.com;ej9309@maxwell.snu.ac.kr;sckim@maxwell.snu.ac.kr;jeongsik-choi722@gmail.com;jeongsikchoi722@gmail.com; | IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY | IEEE T VEH TECHNOL | 0018-9545 | 1939-9359 | 72 | 10 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;TRANSPORTATION SCIENCE & TECHNOLOGY | 2023 | 6.1 | 12.2 | 0.79 | 2025-06-25 | 5 | 6 | Fine timing measurement (FTM); site survey; pedestrian dead reckoning (PDR); WiFi positioning system | LOCALIZATION; ALGORITHM | Fine timing measurement (FTM); pedestrian dead reckoning (PDR); site survey; WiFi positioning system | Global positioning system; IEEE Standards; Location; Timing circuits; Wi-Fi; Wireless local area networks (WLAN); Access points; Fine timing measurement; Pedestrian dead reckoning; Pedestrian dead reckonings; Performances evaluation; Site surveys; Survey methods; Timing measurement; Wi-Fi positioning system; Wireless fidelities; Trajectories | English | 2023 | 2023-10 | 10.1109/tvt.2023.3275203 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Linear Time-Varying MPC-Based Autonomous Emergency Steering Control for Collision Avoidance | In this paper, we propose an autonomous emergency steering (AES) control strategy for the automated vehicle to avoid collisions with obstacles while maintaining the vehicle's yaw stability. Specifically, by capturing the surrounding traffic environment (i.e., dynamic/static obstacles and lane-road boundary) using an artificial potential field approach, a safe vehicle path trajectory in the form of a polynomial function was generated via Pontryagin's maximum principle (PMP). The generated pathwas complemented by a linear time-varying model predictive control (LTV-MPC) scheme that can predict the state behaviors near the operating points during the prediction horizon. Therefore, the proposed approach can effectively and dynamically adapt to the changes in the system model while respecting the state-and-control constraints. Furthermore, we assumed harsh driving environments where the vehicle drives on a slippery road at a relatively high speed, which may cause lateral instability to the vehicle. Hence, the developed controller has to consider both the vehicle's yaw stability and the path-tracking performance. To achieve this goal, we imposed the adaptive constraints in the designed LTV-MPC, depending on the road surface and driving conditions to prioritize the satisfaction of vehicle yaw stability instead of the path-tracking performance. The proposed approach was verified under various conditions using high-fidelity vehicle dynamics and control testing software (i.e., CarSim). Its effectiveness in vehicle yaw stability and path-tracking performance is compared to conventional baseline approaches. | Nguyen, Hung Duy; Kim, Dongryul; Son, Young Seop; Han, Kyoungseok | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Robot & Smart Syst Engn, Daegu 41566, South Korea | Nguyen, Hung/JXL-7245-2024 | 57225877690; 58137887800; 35203958300; 56465294700 | nguyenduyhung@knu.ac.kr;ddyul@knu.ac.kr;ys.son@knu.ac.kr;kyoungsh@knu.ac.kr; | IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY | IEEE T VEH TECHNOL | 0018-9545 | 1939-9359 | 72 | 10 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;TRANSPORTATION SCIENCE & TECHNOLOGY | 2023 | 6.1 | 12.2 | 3.8 | 2025-06-25 | 21 | 31 | Autonomous emergency steering; emergency collision avoidance; linear time-varying model predictive control; optimal path planning; Pontryagin's maximum principle | MODEL-PREDICTIVE CONTROL; DYNAMICS; SYSTEMS; YAW | Autonomous emergency steering; emergency collision avoidance; linear time-varying model predictive control; optimal path planning; Pontryagin's maximum principle | Automobile drivers; Automobile steering equipment; Collision avoidance; Maximum principle; Motion planning; Predictive control systems; Roads and streets; Software testing; Stability; Steering; Time varying control systems; Vehicle performance; Autonomous emergency steering; Collisions avoidance; Computational modelling; Emergency collision avoidance; Linear time varying models; Linear time-varying model predictive control; Model-predictive control; Optimal path planning; Pontryagin's maximum principle; Predictive control; Predictive models; Road; Vehicle's dynamics; Model predictive control | English | 2023 | 2023-10 | 10.1109/tvt.2023.3269787 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Multilayered hydrocarbon ionomer/PTFE composite electrolytes with enhanced performance for energy conversion devices | A new multilayered composite membrane was prepared by impregnating a sulfonated poly(arylene ether sulfone) (SPAES) ionomer into a porous polytetrafluoroethylene (PTFE) substrate for application in proton exchange membrane fuel cells (PEMFCs) and water electrolyzers (PEMWEs). The PTFE substrate was treated with n-propyl alcohol to mediate the interfacial interactions between the SPAES solution and PTFE. Using the 10-and 5 -mm -thick PTFE substrates, three-layered and five-layered composite membranes were pre-pared, respectively, to investigate the effect of PTFE thickness on impregnation of the SPAES ionomer. When 5 -mm-thick PTFE was applied, the SPAES ionomer was effectively impregnated without noticeable defects, indicating a strong interlocking structure between the two incompatible components. Therefore, the five-layered composite membrane showed enhanced dimensional stability and mechanical properties compared to the SPAES membrane, and the effect of the PTFE on proton conductivity was minimized. Conse-quently, the cell performances of the five-layered composite membrane were reflected by current densities of 1.71 A/cm2 at 0.5 V and 9.76 A/cm2 at 1.9 V for PEMFC and PEMWE, respectively, corresponding to 44% and 32% increases compared to those of Nafion 212, owing to its smaller membrane resistance. Moreover, the prepared composite membrane presented excellent durability, which resulted in stable wet-dry cyclability and low degradation rates.(c) 2022 The Author(s).

| ○ | ○ | Article | One-step fabrication of poly(aniline-co-2,5 dimethoxyaniline) nanohybrid coated graphitic sheet electrode for efficient energy application | In this study, a facile one-step homogeneous electrochemical deposition method was utilized to fabricate poly(aniline-2,5-dimethoxyaniline)co-polymer (PANI-PDMA) nano -composite coated on the surface of graphite sheet (GS) electrode for an effective high -performance supercapacitor application. Physio-chemical characterizations were exam-ined using FT-IR, XRD, and energy-dispersive X-ray spectroscopy (EDX) techniques. The morphological view of as-synthesized copolymer nanocomposite was characterized using the FE-SEM technique. Electrochemical investigation of the as-fabricated modified elec-trode (GS/PANI-PDMA) was studied using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and galvanostatic charging and discharging (GCD) studies. Based on electrochemical studies, GS/PANI-PDMA modified co-polymer electrode shows a high specific capacitance of 595 F/g compared to GS@PANI and GS@PDMA. After 1000 cy-cles, it indicates 67% capacitance retention, which is indicated to be a potential alternative material for supercapacitor application.& COPY; 2022 Hydrogen Energy Publications LLC.

| ○ | ○ | Article | Public Blockchain-Envisioned Security Scheme Using Post Quantum Lattice-Based Aggregate Signature for Internet of Drones Applications | Due to high effectiveness and robust security protocols, lattice-based cryptography becomes a very broadly applicable optimistic post-quantum technique that is recently used in public key cryptosystem. An aggregate signature scheme enables a party to bundle a set of signatures together into a single short cryptographic signature, which can be verified by any verifier using the public information. In this paper, we provide a lattice-based aggregate signature scheme where the security depends on the difficulty of the Ring Learning-with-Error (Ring-LWE) problem. Next, we use the basic scheme in Internet of Drones (IoD) applications using the blockchain technology for secure and transparent data storage. The detailed security analysis and comparative study show that the proposed scheme provides superior security including resistance to quantum attacks and is efficient as compared to the existing state of art approaches. The testbed experimental results and the blockchain simulation demonstrate that the proposed scheme can be applied in real-life drones applications. | Bagchi, Prithwi; Maheshwari, Raj; Bera, Basudeb; Das, Ashok Kumar; Park, Youngho; Lorenz, Pascal; Yau, David K.

| ○ | ○ | Article | Security Compliant and Cooperative Pseudonyms Swapping for Location Privacy Preservation in VANETs | Vehicular Ad-hoc Networks (VANETs) are an essential part of the Intelligent Transportation System (ITS). VANETs promise to offer drivers and passengers safety, traffic efficiency, and infotainment services. To this end, VANETs require vehicles to periodically broadcast unencrypted beacon messages that contain position, velocity, timestamp, and identity. Consequently, VANETs naturally expose users' identities and locations, facilitating tracking by an adversary. To address VANETs location privacy issues, researchers have proposed different pseudonym-based privacy-preserving techniques in the literature. One of the techniques is pseudonym swap. In pseudonym swap techniques, vehicles exchange pseudonyms with each other hence fewer pseudonyms for each vehicle since vehicles can reuse pseudonyms. However, existing pseudonym swap-based schemes either exchange pseudonyms via Roadside Units (RSUs) or ignore VANETs' security requirements by not informing the Certification Authority of the exchanges. Hence, they suffer from high RSUs deployment costs, inflexibility to location privacy preservation, unaccountability, and repudiation attacks. Moreover, the lower level of location privacy provided by the schemes demands further improvements. Therefore, we propose a novel pseudonym swap scheme that uses swappable and non-swappable pseudonyms to attain infrastructure independence while adhering to VANET security requirements. In this scheme, vehicles, independent of RSUs, cooperatively swap and change pseudonyms within mix-contexts having a high level of location privacy. Each exchange is then reported to the authority to enforce accountability and non-repudiation. Besides adhering to VANET security requirements, the simulation experiments show that our scheme outperforms existing pseudonym swap schemes, providing VANET users with a high level of location privacy. | Mdee, Abdueli Paulo; Khan, Muhammad Toaha Raza; Seo, Junho; Kim, Dongkyun | Kyungpook Natl Univ, Wireless & Mobile Internet Lab MoNet, Sch Comp Sci & Engn, Daegu 41566, South Korea | Khan, Muhammad Toaha Raza/KXR-8209-2024; Khan, Turyalai/HPH-0061-2023 | 57766373000; 57202044597; 57208740581; 35753648800 | apmdee@knu.ac.kr;toaha@knu.ac.kr;jhseo@knu.ac.kr;dongkyun@knu.ac.kr; | IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY | IEEE T VEH TECHNOL | 0018-9545 | 1939-9359 | 72 | 8 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;TRANSPORTATION SCIENCE & TECHNOLOGY | 2023 | 6.1 | 12.2 | 2.36 | 2025-06-25 | 18 | 18 | Privacy; Vehicular ad hoc networks; Safety; Security; Cryptography; Data privacy; Spatiotemporal phenomena; Location privacy; vehicular Ad-hoc networks; swappable and non-swappable pseudonyms; swap protocol; mix-context | SCHEME; INTERNET; STRATEGY | Location privacy; mix-context; swap protocol; swappable and non-swappable pseudonyms; vehicular Ad-hoc networks | Cryptography; Data privacy; Intelligent systems; Intelligent vehicle highway systems; Location; Network security; Vehicles; Location privacy; Mix-context; Privacy; Roadside units; Security; Spatiotemporal phenomenon; Swap protocol; Swappable and non-swappable pseudonym; Vehicular Adhoc Networks (VANETs); Vehicular ad hoc networks | English | 2023 | 2023-08 | 10.1109/tvt.2023.3254660 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Silicon-stabilized lithium metal powder (SLMP) composite anodes for fast charging by in-situ prelithiation | Advanced battery properties, such as high specific energy density and fast charging, are currently in demand owing to the expansion of the electric vehicle (EV) market. Si and Li metals have attracted research attention as anode materials because of their large theoretical capacities and fast reaction rates with Li ions. However, extreme volume changes and solid electrolyte interphase (SEI) issues hinder their applications in EVs. Herein, we mix Si with stabilized lithium metal powder (SLMP) to achieve a composite anode with complementary characteristics of Si and SLMP (SiLP) that does not require carbon additives. Prelithiation is performed before applying an external current to contribute to a fast reaction rate because of the exclusion of the Si lithiation process and the plating process conducted during the initial charging state. Furthermore, a stable lithium fluoride layer is formed to mitigate SEI issues by adding a fluorinated polymer during electrode fabrication. Capacity characteristics are improved by more than double and a high SiLP anode initial Coulombic efficiency (ICE) of 70% is attained. In addition, the diminished SiLP adsorption energy is provided via density functional theory (DFT) calculations. | Jang, Eunbin; Ryu, Seokgyu; Kim, Myeongjin; Choi, Junghyun; Yoo, Jeeyoung | Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea; Korea Inst Ceram Engn & Technol, Energy Storage Mat Ctr, Jinju 52851, South Korea | ; Yoo, Jeeyoung/AAH-1359-2019 | 57837176500; 57192435552; 55541419000; 59883103900; 56046607500 | jchoi@kicet.re.kr;jyoo@knu.ac.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 | 2.09 | 2025-06-25 | 16 | 19 | Silicon anode; Stabilized lithium metal powder; Prelithiation; Fast charging; SEI layer; Density functional theory calculations | LI-ION BATTERIES; HIGH-ENERGY; LAYER; ELECTRODE; CHALLENGES; DENDRITES; FLUORIDE; BEHAVIOR; SEI | Density functional theory calculations; Fast charging; Prelithiation; SEI layer; Silicon anode; Stabilized lithium metal powder | Additives; Anodes; Charging (batteries); Density functional theory; Fluorine compounds; Lithium batteries; Lithium Fluoride; Powder metals; Seebeck effect; Silicon; Solid electrolytes; Solid-State Batteries; Composite anodes; Density-functional theory calculations; Fast charging; Faster reactions; Interphase layers; Pre-lithiation; Silicon anode; Solid electrolyte interphase; Solid electrolyte interphase layer; Stabilized lithium metal powders; Reaction rates | English | 2023 | 2023-10-01 | 10.1016/j.jpowsour.2023.233326 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
