○ ○ Article ⓘ Magnetic kaolinite immobilized chitosan beads for the removal of Pb(II) and Cd(II) ions from an aqueous environment ⓘ In recent decades, magnetic bead material has attracted considerable attention in water and wastewater purification. In this study, the potential of magnetic kaolinite immobilized in chitosan beads (MKa@CB) to remove Pb(II) and Cd(II) ions from an aqueous environment has been successfully investigated. The addition of magnetic kaolinite generates more active sites, whereas that of chitosan enhances the stability of synthesized bead materials, which enable them to effectively interact with the targeted contaminants. Various factors including agitation time, solution pH, and competitive ions were examined to optimize the removal efficiency of the MKa@CB. The adsorption kinetics and isotherm studies indicated that the adsorption fitted well to the pseudosecond-order kinetic model as well as to the Langmuir isotherm. The prepared adsorbent could be reused up to four cycles without any significant adsorption capacity loss. Thus, the synthesized MKa@4%CB can be a promising adsorbent in effectively removing Pb(II) and Cd(II) from water. ⓘ Elanchezhiyan, S. Sd; Karthikeyan, Perumal; Rathinam, Karthik; Farzana, M.

○ ○ Article ⓘ Optimum oxidation for direct and efficient extraction of carboxylated cellulose nanocrystals from recycled MDF fibers by ammonium persulfate ⓘ For the first time, this study demonstrates a direct extraction of carboxylated cellulose nanocrystals (c-CNCs) from recycled medium density fiberboard (r-MDF) fibers by ammonium persulfate (APS) without any chemical pre-treatment. The aim of this research was to find an optimum condition for isolating c-CNCs from r-MDF fibers by studying the effect of reaction parameters on the characteristics of c-CNCs. The rod-like c-CNCs had an average length and width of 170 to 365 nm and 13 to 17 nm, leading to an aspect ratio of 13 similar to 21. The optimum conditions for a maximum yield and crystallinity were obtained at a reaction temperature of 70 degrees C, reaction time of 16 h and APS concentration of 1.5 mol L-1. Thermal analysis also revealed lower thermal stability of the c-CNCs compared to r-MDF fibers. The APS oxidation is a viable option for converting r-MDF fibers into value-added c-CNCs. ⓘ Khanjanzadeh, Hossein; Park, Byung-Dae ⓘ Kyungpook Natl Univ, Dept Wood & Paper Sci, Daegu 41566, South Korea ⓘ Park, Byung-Dae/ABB-1934-2020; Khanjanzadeh, Hossein/B-7794-2018 ⓘ 37048874200; 7402834820 ⓘ byungdae@knu.ac.kr; ⓘ CARBOHYDRATE POLYMERS ⓘ CARBOHYD POLYM ⓘ 0144-8617 1879-1344 251 SCIE CHEMISTRY, APPLIED;CHEMISTRY, ORGANIC;POLYMER SCIENCE ⓘ 2021 10.723 2.7 3.34 2025-07-30 ⓘ 52 52 Recycled MDF fiber; Cellulose nanocrystals; Ammonium persulfate; Oxidation; Carboxylic groups ⓘ SULFURIC-ACID HYDROLYSIS; HIGH-YIELD; OXIDIZED NANOCELLULOSE; STRATEGY; PREPARE; VALORIZATION; DEGRADATION; COMPOSITES; FIBERBOARD; WASTE ⓘ Ammonium persulfate; Carboxylic groups; Cellulose nanocrystals; Oxidation; Recycled MDF fiber ⓘ Ammonium Persulfate; Cellulose; Crystallinity; Extraction; Fibers; Recycling; Ammonium persulfate; Aspect ratio; Cellulose; Cellulose nanocrystals; Crystallinity; Extraction; Fibers; Recycling; Thermoanalysis; Thermodynamic stability; Average length; Chemical pre-treatment; Direct extraction; Optimum conditions; Reaction parameters; Reaction temperature; Recycled medium; Cellulose derivatives ⓘ English 2021 2021-01-01 10.1016/j.carbpol.2020.117029 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Preparation of cellulose microfibril (CMF) from Gelidium amansii and feasibility of CMF as a cosmetic ingredient ⓘ Cellulose microfibrils (CMF) were successfully isolated from the red alga, Gelidium amansii. G. amansii was processed in two stages, microwave digestion and high-speed blending to remove agar and extract microfibrils, respectively. After pretreatment at 180 degrees C for 10 min, G. amansii containing 40.1 % glucan was microfibrillated through homogenization. Morphological analysis by SEM and FTIR, and analysis of the degree of fibrillation with water retention, sedimentation, and CtCBD3 protein binding of G. amansii-derived CMF were investigated. Functional analysis of CMF showed suppression of cyclooxygenase-2 expression in both in vitro and in vivo experiments. Additionally, suppression was evident in the: i) epidermal thickness of mice skin; ii) presence of proinflammatory cytokines; and iii) inhibition of JNK1/2 and p38 phosphorylation in human keratinocyte HaCaT cells. Such activity demonstrates its anti-inflammatory properties. The results in this study showed the possibility of using CMF derived from a red alga as an anti-inflammation material. ⓘ Jang, Jeong Hwa; So, Bo Ram; Yeo, Hyeon Jin; Kang, Hye Jee; Kim, Min Jeong; Lee, Jeong Jae; Jung, Sung Keun; Jung, Young Hoon ⓘ Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Chungnam Natl Univ, Div Anim & Dairy Sci, Daejeon 34134, South Korea; Kyungpook Natl Univ, Inst Agr Sci & Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Fermentat Biotechnol, Daegu 41566, South Korea ⓘ Jung, Young Hoon/F-1703-2013; Jung, Young/F-1703-2013; Jung, SUNG KEUN/AGR-2623-2022 ⓘ 57208244041; 57218122440; 57208240157; 57219656318; 57215818497; 55915465100; 35310491400; 55550063700 ⓘ younghoonjung@knu.ac.kr;skjung04@knu.ac.kr; ⓘ CARBOHYDRATE POLYMERS ⓘ CARBOHYD POLYM ⓘ 0144-8617 1879-1344 257 SCIE CHEMISTRY, APPLIED;CHEMISTRY, ORGANIC;POLYMER SCIENCE ⓘ 2021 10.723 2.7 1.71 2025-07-30 ⓘ 24 24 Red algae; Gelidium amansii; Cellulose microfibril; Anti-inflammation; Cosmetic ingredients ⓘ ⓘ Anti-inflammation; Cellulose microfibril; Cosmetic ingredients; Gelidium amansii; Red algae ⓘ Analysis; Biochemistry; Cellulose Derivatives; Fibrillation; Fibrils; Mammals; Mixing; Algae; Biochemistry; Cellulose; Cosmetics; Mammals; Pathology; Anti-inflammation; Cellulose microfibrils; Cosmetics ingredient; Gelidium amansii; Glucans; High Speed; Microfibril; Morphological analysis; Pre-treatments; Red algae; Blending ⓘ English 2021 2021-04-01 10.1016/j.carbpol.2020.117569 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Synthesis of magnetic chitosan biopolymeric spheres and their adsorption performances for PFOA and PFOS from aqueous environment ⓘ Due to numerous applications and excellent environmental stability, long-chain perfluorinated chemicals (PFCs) are ubiquitous in water across the world and adversely affect the living organisms. Thus, this study focused on the mitigation of the most frequently used long-chain PFCs namely perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) from water using reduced graphene oxide modified zinc ferrite immobilized chitosan beads (rGO-ZF@CB) as an adsorbent. The results from the adsorption isotherm and kinetic studies revealed that the adsorption data fitted well to the Langmuir and the pseudo-second-order models. According to the Langmuir isotherm, the rGO-ZF@CB possessed the maximum adsorption capacity of 16.07 mg/g for PFOA and 21.64 mg/g for PFOS. Both the electrostatic attractions and hydrophobic interactions have driven the removal of PFOA and PFOS by prepared rGO-ZF@CB. Eventually, the rGO-ZF@CB could be considered as an efficient adsorbent for the effective removal of PFOA and PFOS molecules from the aqueous environment. ⓘ Elanchezhiyan, S.

○ ○ Article ⓘ A nonbiodegradable scaffold-free cell sheet of genome-engineered mesenchymal stem cells inhibits development of acute kidney injury ⓘ Cell therapy using genome-engineered stem cells has emerged as a novel strategy for the treatment of kidney diseases. By exploiting genome editing technology, human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) secreting an angiogenic factors or an anti-inflammatory factor were generated for therapeutic application in acute kidney injury. Junction polymerase chain reaction analysis verified zinc finger nucleases-assisted integration of the desired gene into the hUC-MSCs. Flow cytometry and differentiation assays indicated that genome editing did not affect the differentiation potential of these mesenchymal stem cells. Protein measurement in conditioned media with the use of ELISA and immunoblotting revealed the production and secretion of each integrated gene product. For cell therapy in the bilateral ischemia-reperfusion mouse model of acute kidney injury, our innovative scaffold-free cell sheets were established using a non-biodegradable temperature-responsive polymer. One of each type of scaffold-free cell sheets of either the angiogenic factor vascular endothelial grown factor or angiopoietin-1, or the anti-inflammatory factor erythropoietin, or alpha-melanocyte-stimulating hormone-secreting hUC-MSCs was applied to the decapsulated kidney surface. This resulted in significant amelioration of kidney dysfunction in the mice with acute kidney injury, effects that were superior to intravenous administration of the same genome-engineered hUC-MSCs. Thus, our scaffold-free cell sheets of genome-engineered mesenchymal stem cells provides therapeutic effects by inhibiting acute kidney injury via angiogenesis or anti-inflammation. ⓘ Park, Hye-Jeong; Kong, Min Jung; Jang, Hyo-Ju; Cho, Jeong-In; Park, Eui-Jung; Lee, In-Kyu; Frokiaer, Jorgen; Norregaard, Rikke; Park, Kwon Moo; Kwon, Tae-Hwan ⓘ Kyungpook Natl Univ, Sch Med, Dept Biochem & Cell Biol, Dongin Dong 101, Taegu 41944, South Korea; Kyungpook Natl Univ, Dept Biomed Sci, Sch Med, Plus KNU Biomed Convergence Program BK21, Taegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Anat, Taegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Taegu, South Korea; Aarhus Univ, Dept Clin Med, Aarhus, Denmark ⓘ ; Frokiaer, Jorgen/KHV-5925-2024; Kwon, Tae-Hwan/ABA-1981-2020; Park, Hye/C-1648-2013; Lee, In-Kyu/AAR-6374-2021; PARK, EUIJUNG/LMO-3130-2024 ⓘ 57213039714; 57194730911; 57214330719; 57201154306; 50961544700; 36071537600; 7007036298; 8642489000; 8785448200; 7202206089 ⓘ thkwon@knu.ac.kr; ⓘ KIDNEY INTERNATIONAL ⓘ KIDNEY INT ⓘ 0085-2538 1523-1755 99 1 SCIE UROLOGY & NEPHROLOGY ⓘ 2021 18.998 2.8 1.15 2025-07-30 ⓘ 17 16 acute kidney injury; angiogenesis; anti-inflammation; genome editing; mesenchymal stem cells ⓘ MELANOCYTE-STIMULATING HORMONE; DOWN-REGULATION; RENAL INJURY; ALPHA-MSH; ISCHEMIA; ERYTHROPOIETIN; IMPROVES; GROWTH; RATS; TRANSPLANTATION ⓘ acute kidney injury; angiogenesis; anti-inflammation; genome editing; mesenchymal stem cells ⓘ alpha intermedin; angiopoietin 1; erythropoietin; polymer; vasculotropin; zinc finger nuclease; acute kidney failure; angiogenesis; animal experiment; animal model; animal tissue; antiinflammatory activity; Article; cell differentiation; cell proliferation; cell structure; cell therapy; controlled study; enzyme linked immunosorbent assay; flow cytometry; gene editing; genetic engineering; human; human cell; immunoblotting; immunohistochemistry; mouse; nonhuman; polymerase chain reaction; priority journal; renal ischemia reperfusion injury; treatment outcome; treatment response; umbilical cord mesenchymal stem cell ⓘ English 2021 2021-01 10.1016/j.kint.2020.07.043 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Continuous and programmable photomechanical jumping of polymer monoliths ⓘ The jumping motion is adapted by Earth's creatures to achieve rapid maneuverability and energyefficient hurdling over uneven terrains or large obstacles. Herein, the continuous photomechanical jumping of polymer monoliths with on-demand height and angle programmability is reported. Upon exposure to actinic light, self-assembled spring-like molecular geometry of azobenzene-functionalized liquid crystalline polymers provide on-demand jumping via snap-through of non-isometric structures. The finite element method simulation quantitatively describes stress-strain responsivity of the experimental jumping. Remarkably, the maximum jumping height reaches 15.5 body length (BL) with the maximum instantaneous velocity of 880 BL s-1. We demonstrate programmable jumping height and angle by varying macroscopic geometry and light intensity profile. Finally, four continuous and directional jumping sequences are demonstrated within 5 s to overcome an obstacle. ⓘ Jeon, Jisoo; Choi, Jun-Chan; Lee, Hyeok; Cho, Woongbi; Lee, Kwangseok; Kim, Jae Gwang; Lee, Jae-Won; Joo, Kyung-Il; Cho, Maenghyo; Kim, Hak-Rin; Wie, Jeong Jae ⓘ Inha Univ, Dept Polymer Sci & Engn, Incheon 22212, South Korea; Inha Univ, Program Environm & Polymer Engn, Incheon 22212, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Seoul Natl Univ, Sch Mech & Aerosp Engn, Seoul 08826, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Seoul Natl Univ, Inst Adv Machines & Design, Seoul 08826, South Korea ⓘ ; Kim, Hak-Rin/T-1897-2019; Wie, Jeong Jae (JJ)/I-9878-2019; Cho, Woongbi/IUN-3686-2023 ⓘ 57205744741; 57033068900; 57188865229; 57220075763; 57223899153; 57211408461; 58377059800; 36680185400; 7401727489; 7410124944; 26041261000 ⓘ mhcho@snu.ac.kr;rineey@knu.ac.kr;wie@inha.ac.kr; ⓘ MATERIALS TODAY ⓘ MATER TODAY ⓘ 1369-7021 1873-4103 49 SCIE MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2021 26.943 2.8 4.83 2025-07-30 ⓘ 87 81 Liquid crystal polymer networks; Molecular machines; Soft robotics; Photomechanical jumping ⓘ SNAP-THROUGH; LIGHT; DRIVEN; LOCOMOTION; ROBOT; MECHANISM ⓘ Liquid crystal polymer networks; Molecular machines; Photomechanical jumping; Soft robotics ⓘ Energy efficiency; Liquid crystals; Energy efficient; Finite element method simulation; Functionalized; Light intensity; Molecular geometries; Polymer monoliths; Programmability; Uneven terrain; Polymers ⓘ English 2021 2021-10 10.1016/j.mattod.2021.04.014 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Review ⓘ Does the dispersion of online review ratings affect review helpfulness? ⓘ The impact of online consumer reviews on online purchase decisions has increased with the growth of e-commerce. This paper tries to explain how rating dispersion impacts the process of review consumption based on the heuristic systematic model. For this research, 10,198 online consumer reviews for 516 DVD products were collected from Amazon.com using a web data crawler. Our results show that when trusting average ratings (i.e., when rating dispersion is low), the incentive to read individual reviews decreases because of the principle of least effort. In this case, consumers consider average ratings to be representative of collective intelligence, so rating inconsistency negatively impacts review helpfulness. On the other hand, when average ratings are not trusted (i. e., when rating dispersion is high), the incentive to read individual reviews increases because of the principle of sufficiency. When it happens, extreme ratings affects review helpfulness more because extreme opinions are not ambiguous. Our findings provide new perspectives to address the inconsistent findings of the previous studies on rating and review helpfulness, and the practical implications for e-commerce platforms. ⓘ Lee, Soyeon; Lee, Saerom; Baek, Hyunmi ⓘ Korea Univ, Sch Media & Commun, 145,Anam Ro, Seoul 02841, South Korea; Kyungpook Natl Univ, Sch Business Adm, 80 Daehakro, Daegu 41566, South Korea ⓘ ; Baek, Hye/T-2076-2019 ⓘ 57221465692; 56023428700; 57543501600 ⓘ sylee0708@korea.ac.kr;saeromlee@knu.ac.kr;lotus1225@korea.ac.kr; ⓘ COMPUTERS IN HUMAN BEHAVIOR ⓘ COMPUT HUM BEHAV ⓘ 0747-5632 1873-7692 117 SSCI PSYCHOLOGY, EXPERIMENTAL;PSYCHOLOGY, MULTIDISCIPLINARY ⓘ 2021 8.957 2.8 6.14 2025-07-30 ⓘ 72 81 Online consumer review; Review helpfulness; Rating dispersion; Extreme rating; Rating inconsistency ⓘ WORD-OF-MOUTH; CONSUMER REVIEWS; NEGATIVITY BIAS; DETERMINANTS; CREDIBILITY; EMOTIONS; CUES ⓘ Extreme rating; Online consumer review; Rating dispersion; Rating inconsistency; Review helpfulness ⓘ Electronic commerce; Amazon.com; Collective intelligences; Online consumer reviews; Online reviews; Purchase decision; Systematic modeling; Web data; article; consumer; cooperation; human; intelligence; Dispersions ⓘ English 2021 2021-04 10.1016/j.chb.2020.106670 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Identification and comparison of missed nursing care in the United States of America and South Korea ⓘ Aims and objectives This study aimed to identify and compare missed nursing care types and reasons between South Korea and the United States of America. Background Patient safety has become a significant task of the healthcare delivery systems worldwide. The omission of nursing care constitutes a growing concern because it threatens both patient safety and nursing care quality. Design This study used a cross-sectional, descriptive and comparative design. Methods Data were collected from registered nurses working in two university-affiliated tertiary hospitals and a general hospital in Korea and a Midwest United States tertiary hospital. In addition, the STROBE checklist was used in this study. Results While substantial, the level of missed nursing care reported by Korean nurses was lower than that of United States nurses. Only three nursing care activities, setting up meals, patient assessment and skin/wound care, did not significantly differed between two countries. More basic nursing care types such as ambulation, feeding and mouth care were missed more than others in both countries. The reasons for missed care differed between two countries. However, both Korean and US nurses reported labour resource problems as reasons for missed care. Conclusions Although the types of missed nursing care differed significantly between countries, both Korean and US nurses reported labour resource problems for the top reasons for missed care. Thus, comparing missed nursing care could assist nursing administrators in developing strategies to improve care quality and patient safety. Relevance to clinical practice The level and reasons for missed nursing care are very influential factors for patient outcomes and patient safety. Appropriate skill mix and staffing are needed to decrease extent of missed care, so that enhancing patient safety and quality of nursing care. ⓘ Lee, Eunjoo; Kalisch, Beatrice J. ⓘ Kyungpook Natl Univ, Coll Nursing, Res Inst Nursing Sci, 101 Dong In Dong Jung Gu, Daegu 700422, South Korea; Univ Michigan, Sch Nursing, Innovat & Evaluat, Ann Arbor, MI 48109 USA ⓘ ⓘ 56502620400; 7006455799 ⓘ jewelee@knu.ac.kr; ⓘ JOURNAL OF CLINICAL NURSING ⓘ J CLIN NURS ⓘ 0962-1067 1365-2702 30 11-12 SCIE;SSCI NURSING ⓘ 2021 4.423 2.8 2.02 2025-07-30 ⓘ 14 14 missed nursing care; patient safety; quality of care; South Korea; staffing ⓘ FAMILY CAREGIVERS; ERRORS; HEALTH; WORKLOAD; IMPACT; LEVEL ⓘ missed nursing care; patient safety; quality of care; South Korea; staffing ⓘ Cross-Sectional Studies; Humans; Nursing Care; Nursing Staff, Hospital; Quality of Health Care; Republic of Korea; United States; cross-sectional study; health care quality; human; nursing care; nursing staff; South Korea; United States ⓘ English 2021 2021-06 10.1111/jocn.15712 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Metal-organic frameworks containing uncoordinated nitrogen: Preparation, modification, and application in adsorption ⓘ Significant progress has been made on metal-organic frameworks (MOFs), especially those with functional groups like amines or carboxylic acid groups.

○ ○ Article ⓘ Relationships between lung function decline and skeletal muscle and fat mass changes: a longitudinal study in healthy individuals ⓘ Background The associations between long-term changes in body mass composition and decline in lung function in healthy adults are unknown. Methods Using a well-defined health check-up database, we first assessed individual longitudinal changes in muscle mass (MM) and fat mass (FM) measured via bioelectrical impedance analyses. Then we classified the enrolled individuals into five body composition groups according to their MM index (MMI) [MM (kg)/height (m)(2)] or FM index (FMI) [FM (kg)/height (m)(2)] change rate quartiles. Linear mixed models adjusted for age, smoking status, height, and body mass index were used to analyse the rate of forced expiratory volume in 1 s (FEV1) decline and body composition groups. Results A total of 15 476 middle-aged individuals (6088 women [mean age +/- standard deviation: 50.74 +/- 7.44] and 9388 men [mean age +/- standard deviation: 49.36 +/- 6.99]) were enrolled. The mean number of measurements was 6.96 (interquartile range [IQR]: 5-9) over an average follow-up period of 8.95 years (IQR: 6.73-11.10). Decrease in MMI was significantly associated with accelerated FEV1 decline in men only (P = 1.7 x 10(-9)), while increase in FMI was significantly associated with accelerated FEV1 decline in both women and men (P = 7.9 x 10(-10) and P < 2.0 x 10(-16) respectively). Linear mixed model analyses indicated that annual increase of 0.1 kg/m(2) in MMI was related to accelerated FEV1 decline by 30.79 mL/year (95% confidence interval [CI]: 26.10 to 35.48 mL/year) in men. Annual increase of 0.1 kg/m(2) in FMI was related to accelerated FEV1 decline by 59.65 mL/year in men (95% CI: 56.84 to 62.28 mL/year) and by 22.84 mL/year in women (95% CI: 18.95 to 26.74 mL/year). In body composition analysis, we found increase in MMI was significantly associated with attenuated FEV1 decline in men only (P = 1.7 x 10(-9)), while increase in FMI was significantly associated with accelerated FEV1 decline in both women and men (P = 7.9 x 10(-10) and P < 2.0 x 10(-16) respectively). Individuals characterized with gain MM combined with loss of FM were associated with the most favourable outcome (i.e. the smallest rate of decline in FEV1) in both women and men. In men, loss of FM over time is more closely related with attenuated FEV1 decline than change in MM (gain or loss). Conclusions Change in body composition over time can be used to identify healthy middle-aged individuals at high risk for rapid FEV1 decline. ⓘ Park, Han-Ki; Lee, So-Hee; Lee, Suh-Young; Kim, Sun-Sin; Park, Heung-Woo ⓘ Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Dept Internal Med, Daegu, South Korea; Seoul Natl Univ Hosp, Healthcare Syst Gangnam Ctr, Seoul, South Korea; Seoul Natl Univ Hosp, Dept Internal Med, Seoul, South Korea; Seoul Natl Univ, Med Res Ctr, Inst Allergy & Clin Immunol, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Internal Med, Seoul, South Korea ⓘ Park, Han-Ki/AAY-3102-2020; Park, Heung-Woo/AAW-7690-2020; Kim, Sang/J-5399-2012; Lee, Seung Eun/ABG-1607-2021 ⓘ 57218664064; 57203597259; 54684477700; 18133911100; 7601567361 ⓘ guinea71@snu.ac.kr; ⓘ JOURNAL OF CACHEXIA SARCOPENIA AND MUSCLE ⓘ J CACHEXIA SARCOPENI ⓘ 2190-5991 2190-6009 12 6 SCIE GERIATRICS & GERONTOLOGY;MEDICINE, GENERAL & INTERNAL ⓘ 2021 12.063 2.8 1.74 2025-07-30 ⓘ 21 21 Lung function; FEV1; Body composition; Sarcopenia; Obesity; Health screening ⓘ SARCOPENIA; MEN; MENOPAUSE; OBESITY; WOMEN ⓘ ⓘ Adult; Body Composition; Female; Forced Expiratory Volume; Humans; Longitudinal Studies; Lung; Male; Middle Aged; Muscle, Skeletal; Article; asthma; body composition; body mass; chronic obstructive lung disease; computer assisted tomography; cystic fibrosis; fat mass; female; follow up; forced expiratory volume; forced vital capacity; human; human experiment; longitudinal study; lung function; major clinical study; male; obesity; people by smoking status; physical activity; skeletal muscle; smoking; thorax radiography; adult; body composition; lung; middle aged ⓘ English 2021 2021-12 10.1002/jcsm.12821 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Rotating between day and night shifts: Factors influencing sleep patterns of hospital nurses ⓘ Aims and Objectives This study aimed to investigate sleep patterns of hospital nurses using a wearable electronic device and determine the influence of rotating day and night shifts and lifestyle factors on their sleep efficiency. Background Nurses working in shifts are vulnerable to sleep disturbances. However, little is known about the influence of rotating day and night shift schedules and healthy lifestyle on nurses' daily sleep patterns. Design Descriptive correlational design. Methods Thirty-two hospital nurses working in shifts and 32 hospital nurses not working in shifts participated in data collection. Their sleep patterns were measured for six consecutive days using Fitbit Charge 3((TM)), and information on alcohol consumption, exercise, and eating habits were assessed using a questionnaire. Data were analysed using repeated measures analysis of variance with post hoc Scheffe's test and hierarchical multiple regression analysis. The study was conducted in accordance with the STROBE guideline. Results Overall, nurses working on rotating day and night shifts had significantly shorter total sleep time, longer sleep onset latency, and lower sleep efficiency than those not working in shifts. In particular, nurses working for 3 or 4 consecutive night shifts had significantly shorter total sleep time, lower sleep efficiency and longer sleep onset latency than those working for 0-2 consecutive night shifts. Rotating day and night shifts and alcohol consumption significantly influenced sleep efficiency. Conclusions A work schedule of >= 3 consecutive night shifts and the habit of alcohol consumption before bed time influence nurses' sleep efficiency. Relevance to Clinical Practice Given the poor sleep pattern among nurses working in shifts, particularly those working on >= 2 consecutive night shifts, it is necessary to develop an optimal shift schedule and a program to promote healthy lifestyle among hospital nurses. ⓘ Shin, Seunghwa; Kim, SuHyun ⓘ Andong Sci Coll, Dept Nursing, Kyungpook, South Korea; Kyungpook Natl Univ, Coll Nursing, Daegu, South Korea ⓘ ⓘ 57224006486; 56664542600 ⓘ suhyun_kim@knu.ac.kr; ⓘ JOURNAL OF CLINICAL NURSING ⓘ J CLIN NURS ⓘ 0962-1067 1365-2702 30 21-22 SCIE;SSCI NURSING ⓘ 2021 4.423 2.8 0.62 2025-07-30 ⓘ 7 5 health behaviour; shift work schedule; sleep; sleep hygiene; wearable electronic devices ⓘ QUALITY; ERRORS ⓘ health behaviour; shift work schedule; sleep; sleep hygiene; wearable electronic devices ⓘ Circadian Rhythm; Hospitals; Humans; Nurses; Sleep; Sleep Disorders, Circadian Rhythm; Work Schedule Tolerance; circadian rhythm; circadian rhythm sleep disorder; hospital; human; nurse; sleep; work schedule ⓘ English 2021 2021-11 10.1111/jocn.15819 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ 64 PI/PDMS hybrid cantilever arrays with an integrated strain sensor for a high-throughput drug toxicity screening application ⓘ Herein, we propose a novel biosensing platform involving an array of 64 hybrid cantilevers and integrated strain sensors to measure the real-time contractility of the drug-treated cardiomyocytes (CMs). The strain sensor is integrated on the polyimide (PI) cantilever. To improve the strain sensor reliability and construct the engineered cardiac tissue, the nanogroove-patterned polydimethylsiloxane (PDMS) encapsulation layer is bonded on the PI cantilever. The preliminary sensing characteristics demonstrate the superior structural integrity, robustness, enhanced sensitivity, and repeatability of the proposed devices. The long-term durability and biocompatibility of the PI/PDMS hybrid cantilever is verified by evaluating the cell viability and contractility. We also validate the proposed biosensing platform for cardiotoxicity measurement by applying it to two specific cardiovascular drugs: quinidine and verapamil. In response to quinidine and verapamil, the engineered CMs exhibited negative inotropic and chronotropic effects. The fabricated cantilever device successfully detected the quinidine-induced adverse effects in CMs such as early after depolarization (EADs) and Torsade de points (TdP) in real-time. The array of hybrid cantilevers with integrated strain sensors has the potential to satisfy the need for innovative analytic platforms owing to its high throughput and simplified data analysis. ⓘ Kim, Dong-Su; Jeong, Yun-Jin; Shanmugasundaram, Arunkumar; Oyunbaatar, Nomin-Erdene; Park, Jongsung; Kim, Eung-Sam; Lee, Bong-Kee; Lee, Dong-Weon ⓘ Chonnam Natl Univ, Sch Mech Engn, Gwangju 61186, South Korea; Kyungpook Natl Univ, Dept Precis Mech Engn, Sangju 37224, Gyeongsangbuk D, South Korea; Chonnam Natl Univ, Dept Biol Sci, Gwangju 61186, South Korea; Chonnam Natl Univ, Ctr Next Generat Sensor Res & Dev, Gwangju 61186, South Korea; Chonnam Natl Univ, Adv Med Device Res Ctr Cardiovasc Dis, Gwangju 61186, South Korea ⓘ Shanmugasundaram, Dr. Arunkumar/ABD-4029-2020; 김, 동수/IAN-1770-2023; Lee, Bong-Kee/D-2687-2011; SHANMUGASUNDARAM, ARUNKUMAR/ABD-4029-2020 ⓘ 56569118200; 56261982700; 55750828400; 57039113100; 57189583605; 55549206200; 35205694500; 34875377700 ⓘ mems@jnu.ac.kr; ⓘ BIOSENSORS & BIOELECTRONICS ⓘ BIOSENS BIOELECTRON ⓘ 0956-5663 1873-4235 190 SCIE BIOPHYSICS;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;CHEMISTRY, ANALYTICAL;ELECTROCHEMISTRY;NANOSCIENCE & NANOTECHNOLOGY ⓘ 2021 12.545 2.9 1.48 2025-07-30 ⓘ 25 23 Hybrid cantilever arrays; Drug screening platform; Long-term stability; Cardiomyocytes; High throughput ⓘ CARDIAC MICROPHYSIOLOGICAL DEVICES; PROLONGATION; DISCOVERY ⓘ Cardiomyocytes; Drug screening platform; High throughput; Hybrid cantilever arrays; Long-term stability ⓘ Biosensing Techniques; Cardiotoxicity; Dimethylpolysiloxanes; Drug-Related Side Effects and Adverse Reactions; Humans; Reproducibility of Results; Biocompatibility; Polydimethylsiloxane; Silicones; dimeticone; polyimide; quinidine; verapamil; Biosensing platforms; Cantilever arrays; Cardiomyocytes; Drug screening platform; High-throughput; Hybrid cantilever array; Long term stability; Real- time; Strain sensors; Verapamil; animal cell; Article; biocompatibility; cardiac muscle cell; cardiotoxicity; cell viability; chronotropism; controlled study; dose response; early after depolarization; encapsulation; engineered heart tissue; heart depolarization; heart muscle contractile force; heart muscle contractility; high throughput screening; inotropism; nonhuman; rat; torsade des pointes; toxicity testing; adverse drug reaction; genetic procedures; human; reproducibility; Nanocantilevers ⓘ English 2021 2021-10-15 10.1016/j.bios.2021.113380 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Effect of a Porous Suture Containing Transforming Growth Factor Beta 1 on Healing After Rotator Cuff Repair in a Rat Model ⓘ Background: The healing failure rate after rotator cuff repair is considerably high. Purpose: To evaluate the effect of a porous suture containing transforming growth factor beta 1 (TGF-beta 1) on the sustained release of TGF-beta 1 and rotator cuff healing in a rat model. Study Design: Controlled laboratory study. Methods: A porous suture was developed, and its tensile strength was measured. TGF-beta 1 was delivered using the porous suture, and a TGF-beta 1 release test and human fibroblast proliferation assay were performed. For the animal experiment, 30 rats were randomly allocated into 3 groups (n = 10 each). A bilateral supraspinatus tendon tear was made in all the rats, and repair was performed. Group 1 received repair only; group 2, repair and a single injection of TGF-beta 1; and group 3, repair using the porous suture containing TGF-beta 1. Eight weeks after repair, biomechanical and histological analyses were performed. Results: The porous suture was successfully developed with mechanical properties compatible with the conventional suture, and the sustained release of TGF-beta 1 from the porous suture was confirmed. In addition, the cell proliferation assay confirmed the biological safety of the porous suture. In the animal experiment, group 3 biomechanically exhibited the largest cross-sectional area and the highest ultimate failure load and ultimate stress (all P < .05). Histological examination revealed that group 3 showed significantly better collagen fiber density and tendon-to-bone maturation than did groups 1 and 2 (all P < .05). Conclusion: The porous suture containing TGF-beta 1 could sustainedly and safely release TGF-beta 1, and its use during rotator cuff repair could improve rotator cuff healing, as assessed on the basis of the biomechanical and histological changes in the rat model in this study. Considering the effectiveness, safety, and convenience of the porous suture without extra effort in surgery, the findings of the present study will have a far-reaching effect on the treatment of rotator cuff tears. ⓘ Yoon, Jong Pil; Kim, Hun-Min; Choi, Jin-Hyun; Kang, Hae Rim; Kim, Dong Hyun; Choi, Young Seo; Kim, Kyung-Rock; Kim, Ja-Yeon; Baek, Samuel; Chung, Seok Won ⓘ Kyungpook Natl Univ, Sch Med, Dept Orthopaed Surg, Daegu, South Korea; Korea Dyeing & Finishing Technol Inst, Funct Mat R&D Grp, Daegu, South Korea; Kyungpook Natl Univ, Coll Agr & Life Sci, Dept Biofibers & Mat Sci, Daegu, South Korea; Konkuk Univ, Sch Med, Dept Orthopaed Surg, Seoul, South Korea ⓘ ; Kim, Sae/AAR-3907-2020 ⓘ 36098548400; 57210831160; 36076723600; 57226320965; 57198637188; 57226311379; 57226312537; 57192382942; 57226301492; 37065938600 ⓘ smilecsw@gmail.com; ⓘ AMERICAN JOURNAL OF SPORTS MEDICINE ⓘ AM J SPORT MED ⓘ 0363-5465 1552-3365 49 11 SCIE ORTHOPEDICS;SPORT SCIENCES ⓘ 2021 7.01 2.9 0.82 2025-07-30 ⓘ 8 8 rotator cuff; transforming growth factor beta 1; porous suture; tendon-to-bone healing ⓘ SUSTAINED-RELEASE; TENDON; PROLIFERATION; TGF-BETA-1; HYDROGEL ⓘ porous suture; rotator cuff; tendon-to-bone healing; transforming growth factor beta 1 ⓘ Animals; Biomechanical Phenomena; Porosity; Rats; Rotator Cuff; Rotator Cuff Injuries; Sutures; Transforming Growth Factor beta1; Wound Healing; transforming growth factor beta1; animal; biomechanics; porosity; rat; rotator cuff; rotator cuff injury; suture; wound healing ⓘ English 2021 2021-09 10.1177/03635465211028547 ⓘ 바로가기 바로가기 바로가기 바로가기
○ Article ⓘ Enhancing the conductivity of PEDOT:PSS films for biomedical applications via hydrothermal treatment ⓘ This paper reports a new biocompatible conductivity enhancement of poly (3,4-ethylenedioxythiophene):poly (styrene sulfonate) (PEDOT:PSS) films for biomedical applications. Conductivity of PEDOT:PSS layer was reproducibly from 0.495 to 125.367 S cm−1 by hydrothermal (HT) treatment. The HT treatment employs water (relative humidity > 80%) and heat (temperature > 61 °C) instead of organic solvent doping and post-treatments, which can leave undesirable residue. The treatment can be performed using the sterilizing conditions of an autoclave. Additionally, it is possible to simultaneously reduce the electrical resistance, and sterilize the electrode for practical use. The key to conductivity enhancement was the structural rearrangement of PEDOT:PSS, which was determined using atomic force microscopy, X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, and ultraviolet–visible spectroscopy. It was found that PEDOT inter-bridging occurred as a result of the structural rearrangement. Therefore, the conductivity increased on account of the continuous conductive pathways of the PEDOT chains. To test the biocompatible enhancement technique for biomedical applications, certain demonstrations, such as the monitoring of joint movements and skin temperature, and measuring electrocardiogram signals were conducted with the hydrothermal-treated PEDOT:PSS electrode. This simple, biocompatible treatment exhibited significant potential for use in other biomedical applications as well. © 2020 Elsevier B.V. ⓘ Jeong, Wooseong; Gwon, Gihyeok; Ha, Jae-Hyun; Kim, Dongha; Eom, Ki-Joo; Park, Ju Hyang; Kang, Seok Ju; Kwak, Bongseop; Hong, Jung-Il; Lee, Shinbuhm; Hyun, Dong Choon; Lee, Sungwon ⓘ Department of Emerging Materials Science, Daegu Gyeongbuk Institute of Science & Technology (DGIST), 333, Techno Jungang-daero, Hyeonpung-myeon, Dalseong-gun, Daegu, 711873, South Korea; Department of Emerging Materials Science, Daegu Gyeongbuk Institute of Science & Technology (DGIST), 333, Techno Jungang-daero, Hyeonpung-myeon, Dalseong-gun, Daegu, 711873, South Korea; Department of Emerging Materials Science, Daegu Gyeongbuk Institute of Science & Technology (DGIST), 333, Techno Jungang-daero, Hyeonpung-myeon, Dalseong-gun, Daegu, 711873, South Korea; Department of Emerging Materials Science, Daegu Gyeongbuk Institute of Science & Technology (DGIST), 333, Techno Jungang-daero, Hyeonpung-myeon, Dalseong-gun, Daegu, 711873, South Korea; Department of Energy Engineering, School of Energy and Chemical Engineering, Ulsan National Institute of Science and Technology (UNIST), Ulsan, 44919, South Korea; Department of Polymer Science and Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Energy Engineering, School of Energy and Chemical Engineering, Ulsan National Institute of Science and Technology (UNIST), Ulsan, 44919, South Korea; Dongguk University, College of Medicine, 32 Dongguk-ro, Ilsandong-gu, Goyangsi, 10326, Gyeonggi-do, South Korea; Department of Emerging Materials Science, Daegu Gyeongbuk Institute of Science & Technology (DGIST), 333, Techno Jungang-daero, Hyeonpung-myeon, Dalseong-gun, Daegu, 711873, South Korea; Department of Emerging Materials Science, Daegu Gyeongbuk Institute of Science & Technology (DGIST), 333, Techno Jungang-daero, Hyeonpung-myeon, Dalseong-gun, Daegu, 711873, South Korea; Department of Polymer Science and Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Emerging Materials Science, Daegu Gyeongbuk Institute of Science & Technology (DGIST), 333, Techno Jungang-daero, Hyeonpung-myeon, Dalseong-gun, Daegu, 711873, South Korea ⓘ ⓘ 57201319474; 57219371850; 57203817516; 57218106364; 57218889919; 57189227357; 55588265000; 25960174800; 24471022400; 7601412423; 15834575400; 56976186600 ⓘ swlee@dgist.ac.kr;dong.hyun@knu.ac.kr; ⓘ Biosensors and Bioelectronics ⓘ BIOSENS BIOELECTRON ⓘ 0956-5663 1873-4235 171 SCIE BIOPHYSICS;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;CHEMISTRY, ANALYTICAL;ELECTROCHEMISTRY;NANOSCIENCE & NANOTECHNOLOGY ⓘ 2021 12.545 2.9 3.49 2025-07-30 ⓘ 54 ⓘ ⓘ Biometric device; Conductive polymer; Conductivity enhancement; Health monitoring; Hydrothermal treatment; PEDOT:PSS ⓘ Biosensing Techniques; Bridged Bicyclo Compounds, Heterocyclic; Electric Conductivity; Polymers; Polystyrenes; Atomic force microscopy; Biocompatibility; Electrodes; Medical applications; Semiconductor doping; Styrene; Water treatment; X ray photoelectron spectroscopy; chemical compound; organic solvent; poly (3,4 ethylenedioxythiophene); poly(styrene sulfonate); unclassified drug; fused heterocyclic rings; poly(3,4-ethylene dioxythiophene); polymer; polystyrene derivative; Biomedical applications; Conductivity enhancement; Electrical resistances; Electrocardiogram signal; Hydrothermal treatments; Poly(styrene sulfonate); Poly-3 ,4-ethylenedioxythiophene; Structural rearrangement; Article; atomic force microscopy; biocompatibility; conductance; electric resistance; humidity; hydrothermal treatment; physical phenomena; Raman spectrometry; residue analysis; temperature; ultraviolet visible spectroscopy; X ray diffraction; X ray photoemission spectroscopy; electric conductivity; genetic procedures; Conducting polymers ⓘ English Final 2021 10.1016/j.bios.2020.112717 ⓘ 바로가기 바로가기 바로가기
○ ○ Review ⓘ The Alpha Magnetic Spectrometer (AMS) on the international space station: Part II - Results from the first seven years ⓘ The Alpha Magnetic Spectrometer (AMS) is a precision particle physics detector on the International Space Station (ISS) conducting a unique, long-duration mission of fundamental physics research in space. The physics objectives include the precise studies of the origin of dark matter, antimatter, and cosmic rays as well as the exploration of new phenomena. Following a 16-year period of construction and testing, and a precursor flight on the Space Shuttle, AMS was installed on the ISS on May 19, 2011. In this report we present results based on 120 billion charged cosmic ray events up to multiTeV energies. This includes the fluxes of positrons, electrons, antiprotons, protons, and nuclei. These results provide unexpected information, which cannot be explained by the current theoretical models. The accuracy and characteristics of the data, simultaneously from many different types of cosmic rays, provide unique input to the understanding of origins, acceleration, and propagation of cosmic rays.
