| ○ | Article | Analyzing Dynamic Heat Generation Characteristics of Battery Cell Using Equivalent Circuit Method | High power battery modules with high energy density are vulnerable to thermal runaway. Therefore, a cooling system is required to maintain a safe temperature. To predict the thermal behavior of a module prior to designing for heat dissipation, the heat fluctuations generated in the cell based on the input current, ambient temperature, and SoC(state of charge) should be reflected precisely. Considering the high cost of numerical analysis of electrochemical cells, a thermal analysis of a battery was performed in this study using a secondary equivalent circuit model. This model predicts the amount of heat by deriving the resistance and capacitance variables of specific SoC from pulse discharge data. Using thermal conduction analysis, the results of numerical analysis under constant current discharge at various C-rates and actual electric-vehicle driving conditions were compared with the experimental results in terms of equivalent properties, and the effectiveness of the secondary equivalent circuit-based thermal analysis was analyzed. | Kim, Jin Beom; Park, Seong Bae; Park, Il Seouk | Kyungpook Natl Univ, Sch Mech Engn, Daegu, South Korea | einstein@knu.ac.kr; | TRANSACTIONS OF THE KOREAN SOCIETY OF MECHANICAL ENGINEERS B | T KOR SOC MEC ENG B | 1226-4881 | 47 | 6 | ESCI | ENGINEERING, MECHANICAL | 2023 | 0.2 | 97.0 | 1 | Lithium Ion Battery; Thevenin's Equivalent Circuit; Electric Vehicle; Battery Thermal Management | MODEL | Korean | 2023 | 2023-06 | 10.3795/ksme-b.2023.47.6.313 | 바로가기 | 바로가기 | 바로가기 | |||||||||||

| ○ | ○ | Article | Higher-Order Beam Analysis of Multiply-Connected Thin-Walled Box Beam Systems Subjected to In-Plane Loads | A one-dimensional beam analysis available for thin-walled closed beam systems (e.g., vehicle body structures), which is fast and easy to change modeling, is required to increase the initial design efficiency. However, unlike the assumptions used in the conventional beam theories, significant sectional deformations occur at a joint of thin-walled beam systems, resulting in complex and more flexible joint responses. In this paper, we propose a onedimensional beam analysis method to capture the complicated behavior of multiply-connected thin-walled box beam that the proposed method predicts joint flexibility with an average error of 10% compared to the shell analysis results. | Choi, Soomin | Kyungpook Natl Univ, Sch Mech Engn, Daegu, South Korea | 56124305600 | schoi@knu.ac.kr; | TRANSACTIONS OF THE KOREAN SOCIETY OF MECHANICAL ENGINEERS A | T KOR SOC MEC ENG A | 1226-4873 | 2288-5226 | 47 | 5 | ESCI | ENGINEERING, MECHANICAL | 2023 | 0.2 | 97.0 | 0.13 | 2025-06-25 | 1 | 1 | Thin-Walled Box Beam System(직사각; Higher-Order Beam Theory(고차; In-Plane Deformation(면내; Joint Equilibrium Condition(조인트; Joint Matching; Condition(조인트연결조건) | JOINT | Higher-Order Beam Theory; In-Plane Deformation; Joint Equilibrium Condition; Joint Matching Condition; Thin-Walled Box Beam System | Thin walled structures; Beam system; Box beam; Equilibrium conditions; Higher-order beam theories; In-plane deformation; Joint equilibrium condition; Joint matching condition; Matching condition; Thin-walled; Thin-walled box beam system; Numerical methods | English | 2023 | 2023-05 | 10.3795/ksme-a.2023.47.5.427 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Higher-Order I-Section Beam Analysis Using Recursive Analysis | To predict the responses of I-section beams (that is, displacements and stresses) under bending loads including end effects, a one-dimensional higher-order beam analysis requires numerous cross-sectional deformation modes. In this study, we establish a new recursive analysis method for I-section beams that can provide as many sectional deformation modes as required. In contrast to earlier studies that calculate the modes numerically by discretizing the cross-section using beam / shell elements, the proposed method derives the modes analytically. Hence, the shape functions of the resulting modes are written in closed form and are thus available irrespective of the cross-sectional dimensions of the I-section beams. Additionally, the resulting recursive relations between sectional shape functions allow us to establish explicit stress-generalized force relations applicable for higher-order I-section beam analysis. To check the validity of the proposed method, several examples of interpreting displacements and stresses of I-section beams are considered. | Choi, Soomin | Kyungpook Natl Univ, Sch Mech Engn, Kyungpook, South Korea | schoi@knu.ac.kr; | TRANSACTIONS OF THE KOREAN SOCIETY OF MECHANICAL ENGINEERS A | T KOR SOC MEC ENG A | 1226-4873 | 2288-5226 | 47 | 9 | ESCI | ENGINEERING, MECHANICAL | 2023 | 0.2 | 97.0 | 0 | I-Section Beam; Higher-Order Beam Theory; Cross-Sectional Deformation; Sectional Shape Function; Recursive Analysis | Korean | 2023 | 2023-09 | 10.3795/ksme-a.2023.47.9.701 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Article | A comparison of synthetic data approaches using utility and disclosure risk measures | This paper investigates synthetic data generation methods and their evaluation measures. There have been increasing demands for releasing various types of data to the public for different purposes. At the same time, there are also unavoidable concerns about leaking critical or sensitive information. Many synthetic data gener-ation methods have been proposed over the years in order to address these concerns and implemented in some countries, including Korea. The current study aims to introduce and compare three representative synthetic data generation approaches: Sequential regression, nonparametric Bayesian multiple imputations, and deep generative models. Several evaluation metrics that measure the utility and disclosure risk of synthetic data are also reviewed. We provide empirical comparisons of the three synthetic data generation approaches with respect to various eval-uation measures. The findings of this work will help practitioners to have a better understanding of the advantages and disadvantages of those synthetic data methods. | An, Seongbin; Doan, Trang; Lee, Juhee; Kim, Jiwoo; Kim, Yong Jae; Kim, Yunji; Yoon, Changwon; Jung, Sungkyu; Kim, Dongha; Kwon, Sunghoon; Kim, Hang J.; Ahn, Jeongyou; Park, Cheolwo | Korea Adv Inst Sci & Technol, Dept Ind & Syst Engn, Daejeon, South Korea; Konkuk Univ, Dept Appl Stat, Seoul, South Korea; Kyungpook Natl Univ, Dept Stat, Daegu, South Korea; Sungshin Womens Univ, Dept Stat, Seoul, South Korea; Seoul Natl Univ, Dept Stat, Seoul, South Korea; Univ Cincinnati, Div Stat & Data Sci, Cincinnati, OH USA; Korea Adv Inst Sci & Technol, Dept Math Sci, Daejeon, South Korea; Korea Adv Inst Sci & Technol, Dept Ind & Syst Engn, 291 Daehak Ro, Daejeon 34141, South Korea; Korea Adv Inst Sci & Technol, Dept Math Sci, 291 Daehak Ro, Daejeon 34141, South Korea | Jung, Sungkyu/AFA-8963-2022 | jyahn@kaist.ac.kr;parkcw2021@kaist.ac.kr; | KOREAN JOURNAL OF APPLIED STATISTICS | KOREAN J APPL STAT | 1225-066X | 2383-5818 | 36 | 2 | ESCI | STATISTICS & PROBABILITY | 2023 | 0.2 | 97.3 | 0 | deep generative model; disclosure risk; nonparametric Bayesian; sequential regression; synthetic data; utility | MULTIPLE IMPUTATION | English | 2023 | 2023-04 | 10.5351/kjas.2023.36.2.141 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | A Case of Orbital Infarction Syndrome in a Patient with Hemophagocytic Lymphohistiocytosis | Purpose: To report a case of orbital infarction syndrome in a patient with hemophagocytic lymphohistiocytosis (HLH).Case summary: A 70-year-old woman with diabetes mellitus and hypertension was referred to the Department of Ophthalmology for sudden-onset left upper eyelid ptosis after being diagnosed with HLH. After 3 days, the best corrected visual acuity in the right eye was 0.8, while there was no light perception in the left eye. In the left eye, the ocular motility examination showed limitations in all fields of gaze. On fundus examination, optic disc pallor, retinal hemorrhage, and narrowed retinal arteries were observed in the left eye. Fluorescein angiography showed no blood flow in the retinal arteries and veins in the left eye. On neck computed tomography angiography, the left distal internal carotid artery was narrowed. Orbit computed tomography showed exophthalmos and extraocular muscle hypertrophy in the left eye. Orbit magnetic resonance imaging confirmed optic nerve edema, enhancement of the optic nerve sheath, and high signal intensity of the intraocular fat in the left eye. Slit-lamp examination revealed ischemia of the anterior segment and ischemic necrosis of the eyelid in the left eye. The patient was diagnosed with orbital infarction syndrome. Conclusions: Several factors may lead to ischemia of the orbital tissues in patients with HLH, including coagulopathy, an increased incidence of blood clots, and inflammation in the orbit. It is necessary to consider the possibility of orbital infarction syndrome when HLH patients present with visual loss, ocular movement limitations, and anterior segment ischemia.

| ○ | ○ | Article | Comparative Analysis of Contact Lens-related Bacterial Keratitis According to Culture Positivity: A 25-year Retrospective Study | Purpose: This study investigated the microbiological profile and clinical characteristics of culture positive (CP) contact lens -related bacterial keratitis (CLBK) and compared them to culture negative (CN) cases.Methods: We retrospectively analyzed 142 CLBK patients hospitalized between January 1998 and December 2022. The CP and CN groups consisted of 79 eyes (100 isolates) and 63 eyes, respectively. We investigated the microbiological profile in the CP group and compared the epidemiology, predisposing factors, clinical characteristics, and treatment outcomes between the CP and CN groups. Poor treatment outcomes were defined as a final best-corrected visual acuity (BCVA) = 7 days (Z = 2.30), initial BCVA = 5 mm2 (Z = 2.05).Conclusions: There were no significant differences in clinical characteristics and treatment outcomes between the CP and CN groups. Poor initial clinical findings and over date use of contact lens were associated with poor treatment outcomes in both groups. | Son, Sunggeun; Moon, Cheol-Won; Cho, Chan-Ho; Lee, Sang-Bumm | Yeungnam Univ, Coll Med, Dept Ophthalmol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea; Inje Univ, Haeundae Paik Hosp, Dept Ophthalmol, Coll Med, Pusan, South Korea; Yeungnam Univ, Coll Med, Dept Ophthalmol, 170 Hyeonchung Ro, Daegu 42415, South Korea | Cho, Chan-Ho/J-4558-2015 | 57211939747; 57219606095; 56915210500; 36628861800 | sbummlee@ynu.ac.kr; | JOURNAL OF THE KOREAN OPHTHALMOLOGICAL SOCIETY | J KOR OPHTHALMOL SOC | 0378-6471 | 2092-9374 | 64 | 12 | ESCI | OPHTHALMOLOGY | 2023 | 0.1 | 97.4 | 0 | 2025-06-25 | 0 | 0 | Bacterial infection; Contact lens; Ulcerative keratitis | MICROBIAL KERATITIS; INFECTIOUS KERATITIS; RISK-FACTORS; CLINICAL-FEATURES; ASSOCIATION; PSEUDOMONAS; FLAGELLUM; BIOFILMS; ADHESION; FLORA | Bacterial infection; Contact lens; Ulcerative keratitis | English | 2023 | 2023-12 | 10.3341/jkos.2023.64.12.1168 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Comparison of Intraocular Pressure Measurements Obtained Using Three Tonometers after Descemet Membrane Stripping Endothelial Keratoplasty | Purpose: To compare the level of agreement between the Goldmann applanation tonometer (GAT), iCare IC200 rebound tonometer (IRT), and noncontact tonometer (NCT) in patients who underwent Descemet membrane stripping endothelial keratoplasty (DSEK), and to identify factors contributing to variations in intraocular pressure (IOP) measurements among the three tonometers.Methods: We retrospectively analyzed the medical records of 41 patients who underwent DSEK. IOP was measured using NCT, IRT, and GAT, in this order. We evaluated the level of agreement among IOP measurements using the three tonometers, and analyzed whether clinical factors affected the results.Results: We analyzed 49 eyes of 41 patients (average age: 62.0 years). The IOP values measured by IRT and NCT were lower than those measured by GAT, although the difference was not significant (p = 0.098 and p = 0.320, respectively). A Bland-Altman plot showed greater agreement between IOP measurements obtained by IRT and GAT than those obtained by NCT and GAT. In multivariate regression analysis, the IOP measured by GAT (8 = 0.215, p = 0.022), corneal curvature (8 =-1.692, p = 0.037), and postoperative duration (8 = 0.042, p = 0.018) affected the difference in IOPs measured by GAT and IRT. The IOP measured by GAT (8 = 0.301, p = 0.013) and corneal curvature (8 =-2.670, p = 0.010) affected the difference in IOP measurements obtained by GAT and NCT.Conclusions: In DSEK eyes, IRT showed good agreement and high correlation with GAT, suggesting that it is useful for IOP measurement. However, the IOP measured by GAT, corneal curvature, and postoperative duration should be considered when measuring IOP with an IRT. | Choi, Jeong Mun; Kang, Yong Koo; Kim, Hong Kyun; Kim, Dai Woo | Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, 130 Dongdeok Ro, Daegu 41944, South Korea | KANG, YONG KOO/IVH-8723-2023 | 58544763500; 57204703736; 57218260940; 57095192800 | proector97@gmail.com; | JOURNAL OF THE KOREAN OPHTHALMOLOGICAL SOCIETY | J KOR OPHTHALMOL SOC | 0378-6471 | 2092-9374 | 64 | 7 | ESCI | OPHTHALMOLOGY | 2023 | 0.1 | 97.4 | 0 | 2025-06-25 | 0 | 0 | Descemet-stripping endothelial keratoplasty; Goldmann applanation tonometer; Icare ic200; Noncontact tonometer; Rebound tonometer | GOLDMANN APPLANATION; CORNEAL THICKNESS; REBOUND TONOMETER; ICARE TONOMETER; RISK-FACTORS; GLAUCOMA; NONCONTACT; ELEVATION; IC200; EYES | Descemet-stripping endothelial keratoplasty; Goldmann applanation tonometer; Icare ic200; Noncontact tonometer; Rebound tonometer | English | 2023 | 2023-07 | 10.3341/jkos.2023.64.7.605 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Hyperviscosity Syndrome-related Retinopathy in a Patient with Waldenström Macroglobulinemia | Purpose: We report a case of retinopathy related to bilateral hyperviscosity syndrome in a patient with Waldenstrom macroglobulinemia.Case summary: A 77-year-old male presented with reduced visual acuities of both eyes 2 months in duration. Fundus examination revealed extensive flame-shaped retinal hemorrhages and venous congestion. Optical coherence tomography (OCT) evidenced macular edema and OCT angiography (OCTA) indicated damage to the superficial and deep capillary plexi of retina and choriocapillaris and dilated large choroidal vessels. We diagnosed central retinal vein occlusion with macular edema and prescribed intravitreal bevacizumab and posterior subtenon triamcinolone injections, however, the edema did not improve. As retinopathy associated with hematological disease was thus suspected, we referred the patient to our department of hematology and oncology for further assessment. He was diagnosed with Waldenstrom macroglobulinemia. After initiation of chemotherapy, the retinal hemorrhage in and macular edema of both eyes decreased. After six chemotherapy cycles, the retinal hemorrhages resolved and the macular edema improved in both eyes. OCTA revealed that the choroidal vessel dilation also improved.Conclusions: In elderly patients presenting with central retinal vein occlusions and macular edema of both eyes, it is important to assess whether the retinopathy is associated with a hyperviscosity syndrome linked to a hematological disease.J Korean Ophthalmol Soc 2023;64(11):1120-1125 | Lee, Hye Jin; Kim, Jin Young; Kim, Yu Min; Do, Jae Rock; Park, Dong Ho; Shin, Jae Pil; Kang, Yong Koo | Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, 130 Dongdeok Ro, Daegu 41944, South Korea | ; KANG, YONG KOO/IVH-8723-2023 | 56008815900; 57198434314; 57211041082; 58600232100; 36676632900; 56517350400; 57204703736 | kykyuri@gmail.com; | JOURNAL OF THE KOREAN OPHTHALMOLOGICAL SOCIETY | J KOR OPHTHALMOL SOC | 0378-6471 | 2092-9374 | 64 | 11 | ESCI | OPHTHALMOLOGY | 2023 | 0.1 | 97.4 | 0 | 2025-06-25 | 0 | 0 | Hyperviscosity syndrome; Optical coherence tomography angiography; Waldenstrom macroglobulinemia | COHERENCE TOMOGRAPHY ANGIOGRAPHY; RETINAL VEIN OCCLUSION; WALDENSTROM MACROGLOBULINEMIA; DETACHMENTS | Hyperviscosity syndrome; Optical coherence tomography angiography; Waldenström macroglobulinemia | Korean | 2023 | 2023-11 | 10.3341/jkos.2023.64.11.1120 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Surgical Outcomes of Hammer-Chisel and Drill Techniques to Create Superior Bony Ostium During Endoscopic Dacryocystorhinostomy | Purpose: We introduce a "cold steel" hammer-chisel technique for endoscopic dacryocystorhinostomy, then compare postoperative outcomes between this technique and a drill technique.Methods: This study included 191 patients (297 eyes) with nasolacrimal duct stenoses or obstructions who underwent endoscopic dacryocystorhinostomy using the hammer-chisel or drill technique. Surgical outcomes were compared via follow-up screening for epiphora and anatomical complications such as granuloma and fibrous membrane formation, canalicular obstruction, and synechiae.Results: Postoperative anatomical complications occurred in 29 eyes (18.6%) in the hammer-chisel group and 51 eyes (36.2%) in the drill group (p = 0.001). The anatomical failure rate was higher in the drill group [28 eyes (19.9%)] than in the hammer-chisel group [18 eyes (11.5%); p = 0.038]. Functional failure was observed in 13 eyes (8.3%) in the hammer-chisel group and 13 eyes (9.2%) in the drill group (p = 0.787). The mean operation time was significantly longer in the drill group (35.5 +/- 10.4 minutes vs. 25.4 +/- 9.1 minutes) (p < 0.001).Conclusions: During endoscopic dacryocystorhinostomy, osteotomy with a hammer-chisel is more successful and leads to fewer complications than osteotomy with a drill. | Lee, Hye Jin; Oh, Jun Ho; Kang, Yong Koo; Kim, Dai Woo; Son, Byeong Jae | Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea; Hanyang Univ, Gimcheon, South Korea; Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, 130 Dongdeok Ro, Daegu 41944, South Korea | KANG, YONG KOO/IVH-8723-2023 | 58770806900; 58770067200; 58770653200; 58770807000; 57197444337 | supersbj@hanmail.net; | JOURNAL OF THE KOREAN OPHTHALMOLOGICAL SOCIETY | J KOR OPHTHALMOL SOC | 0378-6471 | 2092-9374 | 64 | 12 | ESCI | OPHTHALMOLOGY | 2023 | 0.1 | 97.4 | 0 | 2025-06-25 | 0 | 0 | Cold steel; Dacryocystorhinostomy; Drill; Hammer-chisel | MECHANICAL ENDONASAL DACRYOCYSTORHINOSTOMY; LASER DACRYOCYSTORHINOSTOMY; OPERATING-ROOM; MANAGEMENT; EPIPHORA | Cold steel; Dacryocystorhinostomy; Drill; Hammer-chisel | Korean | 2023 | 2023-12 | 10.3341/jkos.2023.64.12.1127 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Association of calcium and potassium with insulin resistance among healthy Korean adults: A cross-sectional study | Objective: The purpose of the present study was to investigate the association of dietary and serum calcium and potassium with insulin resistance indicators in healthy adults for the prevention of diabetes. Materials and methods: Anthropometric measurements, blood collection, and dietary intake surveys using 24-hours dietary recall were conducted in 640 healthy adults aged 19 - 69 years. Dietary nutrient intake, and serum levels of calcium, potassium, glucose, and insulin were analyzed. Results: The average age of both males and females was 43.7 years. Daily energy intake was 2,093.9 kcal for males and 1,795.5 kcal for females. Serum calcium was significantly correlated with insulin resistance indicators, including fasting insulin, homeostatic model assessment for insulin resistance (HOMA-IR), and quantitative insulin sensitivity check index (QUICKI), especially in women. In addition, the serum calcium of females with insulin resistance was significantly higher than that of normal females. For potassium, serum levels showed a significant association with fasting serum glucose, but no significant association with insulin resistance was found. Conclusion: Among dietary and serum calcium and potassium, serum calcium was found to be significantly associated with insulin resistance especially in women. | Heo, Young-Ran; Lee, Yeon-Kyung; Hyun, Taisun; Ro, Heekyong; Choi, Mi-Kyeong | Chonnam Natl Univ, Div Food & Nutr, Gwangju, South Korea; Kyungpook Natl Univ, Dept Food Sci & Nutr, Daegu, South Korea; Chungbuk Natl Univ, Dept Food & Nutr, Cheongju, South Korea; Dongshin Univ, Dept Food & Nutr, Naju, South Korea; Kongju Natl Univ, Div Food Sci, Yesan, South Korea; Kongju Natl Univ, Dept Food & Nutr, 54 Daehak Ro, Yesan 32439, South Korea | Lee, Yeon-Kyung/AAA-1916-2020 | mkchoi67@kongju.ac.kr; | TRACE ELEMENTS AND ELECTROLYTES | TRACE ELEM ELECTROLY | 0946-2104 | 40 | 2 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;ENDOCRINOLOGY & METABOLISM | 2023 | 0.1 | 98.1 | 0 | calcium; diet; glucose; insulin resistance; potassium; serum | TYPE-2 DIABETES-MELLITUS; LIFE-STYLE INTERVENTION; BETA-CELL FUNCTION; SERUM-CALCIUM; ATHEROSCLEROSIS-RISK; DISEASE; MORTALITY; GLUCOSE | English | 2023 | 2023 | 10.5414/te500041 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | The association between alcohol drinking and subjective salty taste preference based on Korean Community Health Survey data | Objectives: Alcohol drinking and excessive sodium intake constitute risk factors for several diseases. The purpose of this study was to analyze the relationship be-tween the frequency and amount of alcohol drinking and subjective salty taste preference and salt-related eating behavior. Materials and methods: The data from the Korean Community Health Survey (2010 - 2013, 2014 - 2017) of more than 16 million Koreans were used to examine the frequency of alcohol drinking and the cumulative odds ratio (COR) for subjective salty taste preference and self-reported salt-related eating behavior when adjusted for sex, age, body mass index, educational level, household income, marital status, and smoking status. Results: Subjective salty taste preference and salt-related eating behavior increased with drinking frequency, with an adjusted odds ratio (AOR) of 1.18 (1.16 - 1.20) for subjective salty taste preference even when drinking less than once a month and drinking 1 - 2 cups at a time. The salty taste preference AOR was as high as 2.25 (2.17 - 2.32) in heavy drinkers with more than 10 cups at a time, four or more times a week. Drinkers liked to dip in soy sauce when eating fried food, and even those who drank less than once a month and consumed 1 - 2 cups at a time had an AOR of 1.28 (1.26 - 1.30) for dipping into soy sauce. The AOR for heavy drinkers with more than 10 cups at a time, four or more times a week was 2.07 (2.00 - 2.14). Conclusion: In Korea, both the frequency and amount of alcohol drinking were found to be associated with subjective salty taste preference. The findings suggest that even people who occasionally drink alcohol in small amounts prefer salt taste and are more likely to consume an excessive amount of salt than people who do not drink alcohol at all. We also found that the salt -related eating behavior of dipping into soy sauce when eating fried food may be a characteristic eating behavior of drinkers. | Ma, Jian; Lee, Yeon-Kyung | Kyungpook Natl Univ, Dept Food Sci Nutr, Daegu, South Korea | Lee, Yeon-Kyung/AAA-1916-2020; Ma, Jian/HLW-5119-2023 | yklee@knu.ac.kr; | TRACE ELEMENTS AND ELECTROLYTES | TRACE ELEM ELECTROLY | 0946-2104 | 40 | 3 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;ENDOCRINOLOGY & METABOLISM | 2023 | 0.1 | 98.1 | 0 | alcohol drinking; salts; food preferences; eating behavior | BLOOD-PRESSURE; ANGIOTENSIN; CONSUMPTION; RISK; DISEASE; BURDEN | English | 2023 | 2023 | 10.5414/te500048 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Centronuclear myopathy with a novel variant (p.Asp646Tyr) in the DNM2 gene exhibits mild clinical manifestations: A case report | Centronuclear myopathy (CNM) is one of the congenital myopathies characterized by centrally located nuclei in the muscle fibers. Currently, more than 30 pathogenic variants in the dynamin 2 (DNM2) genes have been identified. Here, we describe a 63-year-old female who presented with slowly progressive limb weakness with no facial weakness or ophthalmoplegia. Electromyographical myotonia without clinical myotonia was noted. In the DNM2 gene, whole-genome sequencing revealed the heterozygous variant c.1936G>T (p.Asp646Tyr), which was not reported previously. Muscle pathology identified many fibers with centrally located nuclei, with the predominance of type 1 fibers. Thus, the patient was finally diagnosed with DNM2-associated CNM with a novel pathogenic variant and with unusually mild phenotype. | Kim, Youngho; Kwack, Mi Hee; Lee, Jong-Mok | Kyungpook Natl Univ Hosp, Dept Neurol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Immunol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurol, 680 Gukchaebosang Ro, Daegu 41944, South Korea | Lee, Jong-Mok/KVY-9550-2024 | 57778218400; 6507685557; 57192075673 | azulmar@gmail.com; | NEUROLOGY ASIA | NEUROL ASIA | 1823-6138 | 28 | 4 | SCIE | CLINICAL NEUROLOGY | 2023 | 0.2 | 98.4 | 0 | 2025-06-25 | 0 | 0 | Whole-genome sequencing; muscle weakness; myotonic disorders | muscle weakness; myotonic disorders; Whole-genome sequencing | creatine kinase; dynamin; myotonic dystrophy protein kinase; adult; ankle dorsiflexion angle; Article; blood examination; case report; centronuclear myopathy; clinical article; electromyography; electrophysiology; female; gait; genetic analysis; histopathology; human; human tissue; immunohistochemistry; limb weakness; middle aged; motor unit potential; muscle action potential; muscle cell; muscle weakness; myotonia; nerve conduction; neurologic examination; ophthalmoplegia; phenotype; ptosis (eyelid); Sanger sequencing; weakness; whole genome sequencing | English | 2023 | 2023-12 | 10.54029/2023feu | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effects of Mixing Ratio and Poling on Output Characteristics of BaTiO3-Poly Vinylidene Fluoride Composite Piezoelectric Generators | BaTiO3-Poly vinylidene fluoride (PVDF) solution was prepared by adding 0 similar to 25 wt% BaTiO3 nanopowder and 10 wt% PVDF powder in solvent. BaTiO3-PVDF film was fabricated by spreading the solution on a glass with a doctor blade. The output performance increased with increasing BaTiO3 concentration. When the BaTiO3 concentration was 20 wt%, the output voltage and current were 4.98 V and 1.03 mu A at an applied force of 100 N. However, they decreased when the over 20 wt% BaTiO3 powder was added, due to the aggregation of particles. To enhance the output performance, the generator was poled with an electric field of 150 similar to 250 kV/cm at 100 degrees C for 12 h. The output performance increased with increasing electric field. The output voltage and current were 7.87 V and 2.5 mu A when poled with a 200 kV/cm electric field. This result seems likely to be caused by the c-axis alignment of the BaTiO3 after poling treatment. XRD patterns of the poled BaTiO3-PVDF films showed that the intensity of the (002) peak increased under high electric field. However, when the generator was poled with 250 kV/cm, the output performance of the generator degraded due to breakdown of the BaTiO3-PVDF film. When the generator was matched with 800 Omega resistance, the power density of the generator reached 1.74 mW/m(2). The generator was able to charge a 10 mu F capacitor up to 1.11 V and turn on 10 red LEDs. | Kim, Hee-Tae; Park, Sang-Shik | Kyungpook Natl Univ, Dept Energy Mat & Chem Engn, Sangju 37224, South Korea; Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, Sangju 37224, South Korea | 58952211300; 7501833211 | parkss@knu.ac.kr; | KOREAN JOURNAL OF MATERIALS RESEARCH | KOR J MATER RES | 1225-0562 | 2287-7258 | 33 | 12 | ESCI | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 0.3 | 98.5 | 0 | 2025-06-25 | 0 | 0 | piezoelectric nanogenerator; BaTiO3-Poly vinylidene fluoride; composite film; poling process | SILVER NANOWIRES; PERFORMANCE; NANOGENERATOR; FILMS | BaTiO3-Poly vinylidene fluoride; composite film; piezoelectric nanogenerator; poling process | Barium titanate; Electric fields; Nanocomposite films; Nanogenerators; Triboelectricity; Batio3-poly vinylidene fluoride; Mixing ratios; Output characteristics; Output current; Output performance; Output voltages; Piezoelectric nanogenerator; Poling process; Poly(vinylidene fluoride); Poly(vinylidene fluoride) composites; Fluorine compounds | English | 2023 | 2023-12 | 10.3740/mrsk.2023.33.12.517 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
