| ○ | ○ | Article | Effects of Cognitive Training in Mild Cognitive Impairmentmeasured by Resting State Functional Imaging | Mild cognitive impairment (MCI) is defined as an intermediate state of cognitive alteration between normal aging and dementia. In this study, we performed a functional network connectivity analysis using resting-state functional magnetic resonance imaging to investigate the association between changes in functional connectivity in the brain and the improvement in cognitive abilities after cognitive training. A computerized cognitive training program was used to improve the abilities of fifteen participants with MCI. The cognitive training program (Comcog), which consists of three weekly sessions totaling 90 min, was conducted with all participants over six weeks. The cognitive abilities before (pre-Comcog) and after (post-Comcog) the cognitive training process were measured using a neurocognitive function test. After the Comcog, the participants enhanced their visual and verbal memories, attention, and visuo-motor coordination. The functional connectivity between cingulo-opercular (CON) and default mode (DMN) showed significant improvements after Comcog training. Therefore, our study suggests that cognitive training may improve the cognitive abilities of participants. This improvement was associated with an increase in the functional connectivity between DMN and CON. The increase in functional connectivity after cognitive training was specifically associated with overall cognitive functions, including executive, memory, decision-making, and motivational functions. | Kim, Seungho; Park, Eunhee; Cha, Hyunsil; Jung, Jae-Chang; Jung, Tae-Du; Chang, Yongmin | Kyungpook Natl Univ, Dept Med & Biol Engn, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Rehabil Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Biol, Daegu 41566, South Korea; Kyungpook Natl Univ Hosp, Dept Radiol, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Mol Med, Daegu 41944, South Korea | 57218284791; 56107216400; 57189728122; 57203377467; 36622364500; 7501840633 | seungho5335@gmail.com;ehmdpark@naver.com;hscha1002@daum.net;jcjung@knu.ac.kr;teeed0522@daum.net;ychang@knu.ac.kr; | BEHAVIORAL SCIENCES | BEHAV SCI-BASEL | 2076-328X | 10 | 11 | ESCI | PSYCHOLOGY, MULTIDISCIPLINARY | 2020 | N/A | 0.55 | 2025-06-25 | 9 | 9 | cognitive impairment; cognitive training; resting-state functional magnetic resonance imaging; functional connectivity | QUALITY-OF-LIFE; ALZHEIMERS-DISEASE; CONNECTIVITY; NETWORK; RISK; DISORDERS; DECLINE; FMRI | Cognitive impairment; Cognitive training; Functional connectivity; Resting-state functional magnetic resonance imaging | English | 2020 | 2020-11 | 10.3390/bs10110175 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Effects of Design and Material Change of Firefighter Station Uniform on Thermal Physiological and Subjective Responses | This study investigated physiological and subjective responses to different types of firefighter station uniforms made with various designs and materials. Six healthy males participated in this study that consisted of 20 min of rest, 30 min of treadmill exercise, and 30 min of recovery in a hot and humid environment (34°C and 65%RH). The experimental clothing conditions were as follows. 1) a fitted T-shirt and trouser made of 100% polyester (FC-Uniform), and 2) flame retardant T-shirts made of acrylic and cotton as well as trousers with aramid and polyester, designed for overfitting (Control). There were no significant differences in the body temperature, and sweat rate between the two conditions; however, the heart rate with the FC-Uniform was significantly lower than Control (p=.025). The clothing microclimate temperature at the chest of the FC-Uniform was significantly lower than the Control (p=.037), and a difference of 1°C was maintained until the recovery was complete. There were no significant differences in the subjective responses; however, participants experienced a humidity sensation faster with FC-Uniform in the recovery phase. The results indicate that changes in the design and material of firefighter station uniforms may have a positive influence on reducing the thermal stress of firefighters ⓒ2020, The Korean Society of Clothing and Textiles.

| ○ | Article | Effects of Encouraging Group Therapy Program on Male Baby-Boomers' Self-esteem, Depression, Suicidal Ideation and Social Interest | Purpose: This study aimed to investigate the effects of an encouraging group therapy program on male baby boomers' self-esteem, depression, suicidal ideation, and social interest. Methods: The recruited participants were 33 male baby boomers in G city. The study was conducted from April 4 to June 10, 2016 To test the effects of the encouraging group therapy program, the participants were divided into two groups: an experimental group (N=15) and a control group (N=18). The data were analyzed using the x2 test, t-test, and Fisher exact test with the SPSS/WIN 22.0 program. Results: Compared to the control group, the experimental group showed significantly increased scores for self-esteem (t=2.40, p=.023) and social interest (t=2.21, p=.040) along with a significant decrease in the depression score (t=-3.39, p=.002); however, the suicidal ideation score was not significantly decreased (t=-0.43, p=.673). Conclusion: The findings from this study indicate that an encouraging group therapy program effectively enhances self-esteem and social interest while reducing depression in male baby boomers. Therefore, this program represents a good strategy that community mental health nurses can use to improve psychiatric health among male baby boomers. © 2020, Korean Society of Nursing Science.

| ○ | Article | Effects of molecular weight and structural conformation of multivalent-based elastin-like polypeptides on tumor accumulation and tissue biodistribution | In order to improve clinical outcomes for novel drug delivery systems, distinct optimization of size, shape, multifunctionality, and site-specificity are of utmost importance. In this study, we designed various multivalent elastin-like polypeptide (ELP)-based tumor-targeting polymers in which multiple copies of IL-4 receptor (IL-4R)-targeting ligand (AP1 peptide) were periodically incorporated into the ELP polymer backbone to enhance the affinity and avidity towards tumor cells expressing high levels of IL-4R. Several ELPs with different molecular sizes and structures ranging from unimer to micelle-forming polymers were evaluated for their tumor accumulation as well as in vivo bio-distribution patterns. Different percentages of cell binding and uptake were detected corresponding to polymer size, number of targeting peptides, or unimer versus micelle structure. As compared to low molecular weight polypeptides, high molecular weight AP1-ELP showed superior binding activity with faster entry and efficient processing in the IL-4R-dependent endocytic pathway. In addition, in vivo studies revealed that the high molecular weight micelle-forming AP1-ELPs (A86 and A100) displayed better tumor penetration and extensive retention in tumor tissue along with reduced non-specific accumulation in vital organs, when compared to low molecular weight non-micelle forming AP1-ELPs. It is suggested that the superior binding activities shown by A86 and A100 may depend on the multiple presentation of ligands upon transition to a micelle-like structure rather than a larger molecular weight. Thus, this study has significance in elucidating the different patterns underlying unimer and micelle-forming ELP-mediated tumor targeting as well as the in vivo biodistribution. © The author(s). | Sarangthem, Vijaya; Seo, Bo-Yeon; Yi, Aena; Lee, Young-Jin; Cheon, Sun-Ha; Kim, Sang Kyoon; Singh, Thoudam Debraj; Lee, Byung-Heon; Park, Rang-Woon | Department of Biochemistry and Cell Biology, School of Medicine, and Cell & Matrix Research Institute, Kyungpook National University, Daegu, 41944, South Korea, Department of Pathology, All India Institute of Medical Sciences, New Delhi, 110029, India; Department of Biochemistry and Cell Biology, School of Medicine, and Cell & Matrix Research Institute, Kyungpook National University, Daegu, 41944, South Korea; Department of Biochemistry and Cell Biology, School of Medicine, and Cell & Matrix Research Institute, Kyungpook National University, Daegu, 41944, South Korea; Department of Biochemistry and Cell Biology, School of Medicine, and Cell & Matrix Research Institute, Kyungpook National University, Daegu, 41944, South Korea; Department of Biochemistry and Cell Biology, School of Medicine, and Cell & Matrix Research Institute, Kyungpook National University, Daegu, 41944, South Korea; Laboratory Animal Center, Daegu-Gyeongbuk Medical Innovation Foundation, Cheombok, Daegu, 41061, South Korea; Department of Medical Oncology Lab, All India Institute of Medical Sciences, New Delhi, 110029, India; Department of Biochemistry and Cell Biology, School of Medicine, and Cell & Matrix Research Institute, Kyungpook National University, Daegu, 41944, South Korea; Department of Biochemistry and Cell Biology, School of Medicine, and Cell & Matrix Research Institute, Kyungpook National University, Daegu, 41944, South Korea | 56001741200; 57191958798; 57201005875; 57191967618; 57191960042; 55862436000; 55190689800; 16304374900; 7401895636 | nwpark@knu.ac.kr; | Nanotheranostics | 2206-7418 | 4 | 2 | 0.61 | 2025-06-25 | 15 | Biodistribution; ELP; IL-4 receptor; Multivalent; Size-dependent; Tumor targeting | Animals; Antineoplastic Agents; Cell Line, Tumor; Drug Carriers; Elastin; Female; Humans; Mice, Inbred BALB C; Micelles; Molecular Weight; Neoplasms; Peptides; Protein Conformation; Receptors, Interleukin-4; Tissue Distribution; Xenograft Model Antitumor Assays; antineoplastic agent; doxorubicin; elastin like polypeptide; interleukin 4 receptor; ligand; paclitaxel; polymer; polypeptide; unclassified drug; antineoplastic agent; AP1 peptide; drug carrier; elastin; interleukin 4 receptor; peptide; 4T1 cell line; animal cell; animal experiment; animal model; Article; cellular distribution; circular dichroism; conformational transition; controlled study; drug design; drug synthesis; electron spin resonance; endosome; ex vivo study; human; human cell; hydrodynamics; immunohistochemistry; in vitro study; in vivo study; lysosome; matrix assisted laser desorption ionization time of flight mass spectrometry; MDA-MB-231 cell line; micelle; molecular size; molecular weight; mouse; nonhuman; particle size; photon correlation spectroscopy; physical chemistry; plasma half life; polyacrylamide gel electrophoresis; protein expression; protein secondary structure; tumor microenvironment; animal; Bagg albino mouse; chemistry; drug screening; female; metabolism; molecular weight; neoplasm; protein conformation; tissue distribution; tumor cell line | English | Final | 2020 | 10.7150/ntno.39804 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Article | Effects of phenolics from oplismenus undulatifolius in α-MSH-stimulated B16F10 melanoma cells | In this study, the efficacy of melanoma cell B16F10 was investigated using the Korean native plant Oplismenus undulatifolius (OU). First, the cell viability of the extract was more than 90% when treated with 15 μg/mL of phenolics from OU. The results showed that melanin biosynthesis and cellular tyrosinase synthesis were inhibited by treatment with α-melanocyte-stimulating hormone-stimulated mouse melanoma cell B16F10 at a concentration of 15 μg/mL of phenolics for cell-line efficacy. The expression of tyrosinase, tyrosinase-related protein (TRP)-1, TRP-2, and microphthalmia transcription factor (MITF) protein was confirmed by western blot to investigate the effect of phenolics from OU on melanin biosynthesis. When treated with phenolics from OU 15 μg/mL, tyrosinase, TRP-1, TRP-2, and MITF decreased the protein expression level. In particular, tyrosinase, TRP-1, and MITF inhibited the production amount to a level similar to that of the non-treated normal group, indicating that the effect was excellent. Therefore, phenolics from OU acts as an inhibitor of tyrosinase, TRP-1, TRP-2, and its transcription factor MITF, and participates in melanin biosynthesis mechanism. These results suggested the potential for development as a material. © The Korean Society for Applied Biological Chemistry 2020. | Park, Hye-Jin; Lee, Eun-Ho; Jung, Hee-Young; Kang, In-Kyu; Cho, Young-Je | School of Food science & Biotechnology, Kyungpook National University, 80 University Street, Bukgu, Daegu, 41566, South Korea; School of Food science & Biotechnology, Kyungpook National University, 80 University Street, Bukgu, Daegu, 41566, South Korea; School of Applied Biosciences, Kyungpook National University, 80 University Street, Bukgu, Daegu, 41566, South Korea; Department of Horticultural Science, Kyungpook National University, 80 Daehakro, Bukgu, Daegu, 41566, South Korea; School of Food science & Biotechnology, Kyungpook National University, 80 University Street, Bukgu, Daegu, 41566, South Korea | 7601567655; 56347429100; 7403029383; 56577308800; 55265396300 | yjcho@knu.ac.kr; | Journal of Applied Biological Chemistry | 1976-0442 | 63 | 1 | 0.14 | 2025-06-25 | 3 | B16F10 mouse melanoma cells; Extract; Oplismenus undulatifolius; α-Melanocyte-stimulating hormone-stimulation | English | Final | 2020 | 10.3839/jabc.2020.012 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Effects of storage time on molecular weights and properties of melamine-urea-formaldehyde resins | As the properties of the melamine-urea-formaldehyde (MUF) resins were changing during their storage time, this study investigated the impacts of the synthesis method and melamine content of the MUF resins on the pH, apparent viscosity, molecular weights, and crystallinity to estimate these properties over storage times of up to 30 days. Melaminesat three addition levels (5, 10, and 20 wt% based on the resin solids) were simultaneously reacted with urea and formaldehyde (MUF-A resins), while those at the same addition levels were first reacted with formaldehyde and then with urea(MUF-B resins). The pH values of the MUF-A and MUF-B resins decreased linearly as the storage time increased; the apparent viscosity increased linearly for the low melamine contents (5% and 10%) but increased exponentially for 20%. As anticipated, the molecular weights (Mw and Mn) increased linearly with the storage time, with a steeper increase in the Mw of the MUF-B resins compared with that of the MUF-A resins. The crystallinity of the two resin types decreased with storage time at higher melamine content. The relationships between these properties and the storage time made it possible to estimate the property changes in these resins synthesized by the different synthesis methods and melamine contents; this could help predict the properties of such resins in the industry during their storage. © 2020, Korean Society of Wood Science Technology.

| ○ | Article | Effects of the Perilla frutescens Britton var. acuta Kudo Ethanol Extract (PFE) on the Improvement of Metabolic Syndrome and Non-Alcoholic Fatty Liver Disease Induced by High-Fat Diet | Perilla frutescens Britton var. acuta Kudo (PF) is a traditional herb that belongs to the lamiaceae family. PF has been reported to have numerous biological activities, including antioxidant, anti-allergic, anti-inflammatory, anticancer, and neuroprotection effects. This study examined the effects of PF ethanol extract (PFE) on obesity and its complications, particularly focusing on non-alcoholic fatty liver disease (NAFLD) in C57BL/6J mice fed high-fat diets (HFD). Male mice were fed a normal diet (ND), a HFD, or HFD+PFE (1% w/w, PFE) for 12 weeks. The PFE treatment ameliorated dyslipidemia and hyperglycemia HFD-induced obese mice coupled with the enhanced energy expenditure. The liver weight and hepatic lipotoxicity markers (GOT and GPT) were reduced significantly in the PFE group than in the HFD group. Moreover, the hepatic lipid profiles and morphological analysis showed less hepatic lipid accumulation in the PFE group than the HFD-fed mice. In particular, the expression of hepatic lipogenic genes (Acc1 and Cidea) was down-regulated, whereas the expression of fatty acid oxidation-related genes (Pgc1α and Pparα) was increased. These results suggest that PFE can prevent or attenuate the development of HFD-induced obesity and NAFLD. © 2020 Korean Society of Food Science and Nutrition.

| ○ | ○ | Article | Effects of the presence of a pediatric intensivist on treatment in the pediatric intensive care unit | Background: There are few studies on the effect of intensivist staffing in pediatric intensive care units (PICUs) in Korea. We aimed to evaluate the effect of pediatric intensivist staffing on treatment outcomes in a Korean hospital PICU. Methods: We analyzed two time periods according to pediatric intensivist staffing: period 1, between November 2015 to January 2017 (no intensivist staffing, n=97) and period 2, between February 2017 to February 2018 (intensivists staffing, n=135). Results: Median age at admission was 5.4 years (range, 0.7-10.3 years) in period 1 and 3.6 years (0.2-5.1 years) in period 2 (P=0.013). The bed occupancy rate decreased in period 2 (75%; 73%-88%) compared to period 1 (89%; 81%-94%; P=0.015). However, the monthly bed turnover rate increased in period 2 (2.2%; 1.9%-2.7%) compared to period 1 (1.5%, 1.1%-1.7%; P=0.005). In both periods, patients with chronic neurologic illness were the most common. Patients with cardiovascular problems were more prevalent in period 2 than period 1 (P=0.008). Daytime admission occurred more frequently in period 2 than period 1 (63% vs. 39%, P<0.001). The length of PICU stay, parameters related with mechanical ventilation and tracheostomy, and pediatric Sequential Organ Failure Assessment score were not different between periods. Sudden cardiopulmonary resuscitations occurred in two cases during period 1, but no case occurred during period 2. Conclusions: Pediatric intensivist staffing in the PICU may affect efficient ICU operations. | Kwon, Jung Eun; Roh, Da Eun; Kim, Yeo Hyang | Kyungpook Natl Univ, Childrens Hosp, Div Pediat Cardiol, Daegu, South Korea; Kyungpook Natl Univ, Dept Pediat, Sch Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea | 57194002366; 57195734230; 57032023800 | kimyhmd@knu.ac.kr; | ACUTE AND CRITICAL CARE | ACUTE CRIT CARE | 2586-6052 | 2586-6060 | 35 | 2 | ESCI | CRITICAL CARE MEDICINE | 2020 | N/A | 0.36 | 2025-06-25 | 3 | 3 | cardiopulmonary resuscitation; child; critical care; intensive care units | MIX-ADJUSTED MORTALITY; STAFFING PATTERNS; ICU ADMISSION; GUIDELINES; OUTCOMES | Cardiopulmonary Resuscitation; Child; Critical Care; Intensive Care Units | English | 2020 | 2020-05 | 10.4266/acc.2019.00752 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Effects of the Realistic Description for the Terminal Fall Velocity-Diameter Relationship of Raindrops on the Simulated Summer Precipitation over South Korea | The effects of the terminal fall velocity-diameter relationship for raindrops, which is prescribed based on the measurement, on the simulated surface precipitation over Korea during summer season were investigated in our study. Two rainfall cases, 1-month summer precipitation and mesoscale rainfall, have been simulated using the Weather Research and Forecasting (WRF) model. The selected cloud microphysics parameterization are WRF Single-Moment 5 class (WSM5) and WRF Single-Moment 6-class (WSM6) in the WRF model. The measured terminal fall-diameter relationship for raindrops by Gunn and Kinzer (1949) was applied in both WSM5 and WSM6. The sensitivity experiments with WSM5 and WSM6, applying the measured fall-diameter relationship, presents the different responses in simulated precipitation amount for the 1-month summer precipitation case. Precipitation increases with WSM5, thus enhancing the precipitation statistical skills. However, precipitation decreases with WSM6 leading to the deterioration of precipitation statistical skills. For the mesoscale rainfall case, precipitation increases with both WSM5 and WSM6, which further enhances the positive bias in precipitation amount. | Kim, Da-Seul; Lim, Kyo-Sun Sunny; Kim, Kwonil; Lee, GyuWon | Kyungpook Natl Univ, Sch Earth Syst Sci, Dept Astron & Atmospher Sci, 80 Daehak Ro, Daegu 41566, South Korea | Lim, Kyo-Sun/I-3811-2012; Kim, Kwonil/HTN-0103-2023 | kyosunlim@knu.ac.kr; | ATMOSPHERE-KOREA | ATMOS-KOREA | 1598-3560 | 2288-3266 | 30 | 4 | ESCI | METEOROLOGY & ATMOSPHERIC SCIENCES | 2020 | N/A | 3 | Terminal fall velocity; raindrops; WSM6; WSM5; summer precipitation | MICROPHYSICS PARAMETERIZATION; REGIONAL CLIMATE; WATER-DROPS; EAST-ASIA; PART I; CLOUD; IMPLEMENTATION; SENSITIVITY; MODEL; SNOW | Korean | 2020 | 2020 | 10.14191/atmos.2020.30.4.421 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | Effects of Thin-Film Thickness on Sensing Properties of SnO2-Based Gas Sensors for the Detection of H2S Gas at ppm Levels | SnO2 thin-film gas sensors were easily created using the ion sputtering technique. The as-deposited SnO(2 )thin films consist of a tetragonal SnO2 phase and densely packed nanosized grains with diameters of approximately 20-80 nm, which are separated by microcracks. The as-deposited SnO2 thin film is well crystallized, with a dense columnar nanostructure grown directly onto the alumina material and the Pt electrodes. The grain size and thickness of SnO2 thin films are easily controlled by varying the sputtering time of the ion coater. The responses of the SnO2 thin-film sensors decrease as the SnO2 film thickness is increased, indicating that a negative association exists between the sensor response and the SnO2 film thickness due to gas diffusion from the surface. The SnO2 thin-film sensor, which was created by ion sputtering for 10 min, shows an excellent sensor response (R-a/R-g, where R-a is the electric resistance under air and R-g is the electric resistance under the test gas) for detecting 1 ppm H2S at 350 degrees C. | Jo, Seong Bin; Kim, Hyun Ji; Ahn, Joong Hee; Hwang, Byung Wook; Huh, Jeung Soo; Ragupathy, Dhanusuraman; Lee, Soo Chool; Kim, Jae Chang | Kyungpook Natl Univ, Res Inst Adv Energy Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Chem Engn, Daegu 41566, South Korea; Greenpia Technol Inc, Seoul 06258, South Korea; Korea Inst Energy Res, Daejeon 34129, South Korea; Kyungpook Natl Univ, Dept Mat Sci & Met, Daegu 41566, South Korea; Natl Inst Technol Puducherry, Dept Chem, Karaikal 609609, India | ; Dhanusuraman, Prof Ragupathy/JVM-8472-2024; Kim, Hyunjin/MDS-5282-2025 | JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY | 1533-4880 | 1533-4899 | 20 | 11 | 6 | Sensor; SnO2; H2S; Thin Film; Ion Sputtering | MECHANISM; BEHAVIOR; ELEMENT; OXIDES | English | 2020 | 2020-11 | 10.1166/jnn.2020.18854 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | Article | Effects of types of input frequency distribution and degrees of explicitness of focus-on-form techniques on second language grammar learning | In an effort to find a way to optimize the learning condition, this study examined the effects of two types of input frequency distribution, skewed-first distribution (SFD) versus balanced distribution (BD), and two types of focus-on-form techniques, input processing (IP) versus input enhancement (IE), on the learning of English participles by Korean middle school students. A total of 91 students participated in this study, divided into five subgroups: SFD + IP, SFD + IE, BD + IP, BD + IE, and Control. The learning outcomes and the generalizability of the learned knowledge were measured through scaled judgment tasks and picture description tasks, immediately after treatment as well as one week later. The results showed that the input frequency distribution factor did not have statistically significant effects on learning and generalizability, while the degrees of explicitness of focus-on-form techniques had statistically significant effects on both. The interaction effects of the two main factors were not statistically significant. More detailed findings are presented with some pedagogical implications for Korean EFL classrooms. © 2020 The Korea Association of Teachers of English (KATE). | Rhee, Jeong-Hyeon; Lee, Sang-Ki | Department of Education, Kyungpook National University, South Korea | 57221676244; 27171490400 | slee@knue.ac.kr; | English Teaching(South Korea) | 1017-7108 | 75 | 2 | 0.13 | 2025-06-25 | 1 | Focus on form; Input enhancement; Input frequency distribution; Input processing; Usage-based language learning | Korean | Final | 2020 | 10.15858/engtea.75.2.202006.111 | 바로가기 | 바로가기 | ||||||||||||||||

Pre-pubertal patients (mean age 6.2 years; height, 107.1 cm) were randomised 2:1 to 12 months' GH treatment (0.469 mg/kg/week; group A, n=36) or 6 months untreated followed by 6 months' GH treatment (group B, n=18). Safety analysis was based on adverse events (AEs) in all GH-treated patients. Results: After 6 months, height velocity (Ht-V), change in both height standard deviation score (Ht-SDS) and insulin-like growth factor 1 (mean difference [95% confidence interval {CI}]: 5.15 cm/year [4.09, 6.21]; 0.57 [0.43, 0.71]; 164.56 ng/mL [112.04, 217.08], respectively; all p<0.0001) were greater in group A than in group B. Mean difference in Ht-V for 0-6 months versus 6-12 months was 2.80 cm/year (95% CI 1.55, 4.04) for group A and -4.60 cm/year (95% CI -6.12, -3.09; both p<0.0001) for group B. No unexpected AEs were reported. Conclusions: During the first 6 months, height was significantly increased in GH-treated patients versus untreated patients with ISS. Safety of GH was consistent with the known safety profile. © Touch Medical Media 2020. | Jung, Min Ho; Suh, Byung-Kyu; Ko, Cheol Woo; Lee, Kee-Hyoung; Jin, Dong-Kyu; Yoo, Han-Wook; Hwang, Jin Soon; Chung, Woo Yeong; Han, Heon-Seok; Prusty, Vinay; Kim, Ho-Seong | Catholic University of Korea, Yeouido St. Mary's Hospital, Seoul, South Korea; Catholic University of Korea, Seoul St. Mary's Hospital, Seoul, South Korea; Kyungpook National University Hospital, Daegu, South Korea; Korea University, Anam Hospital, Seoul, South Korea; Samsung Medical Center, Sung Kyun Kwan University, Seoul, South Korea; Asan Medical Center, Seoul, South Korea; Ajou University Hospital, Suwon, South Korea; Inje University, Busan Paik Hospital, Busan, South Korea; Chungbuk National University Hospital, Chungbuk National University, College of Medicine, Cheongju, South Korea; Novo Nordisk Pharma Gulf FZ-LLC, Dubai, United Arab Emirates; Severance Hospital, Yonsei University Health System, Seoul, South Korea | 56063372000; 23026105800; 7202596445; 8629768500; 55666965500; 7201373304; 35205334700; 8605959600; 35276984600; 35724393900; 37031208400 | kimho@yuhs.ac; | European Endocrinology | 1758-3772 | 16 | 1 | 0.28 | 2025-06-25 | 4 | Clinical trial; Human growth hormone; Idiopathic; Short stature | human growth hormone; nordilet; somatomedin binding protein 3; somatomedin C; allergic rhinitis; Article; child; conjunctivitis; controlled study; dermatitis; disease severity; dizziness; drug efficacy; drug safety; evaluation study; eye disease; fatigue; female; fever; hormonal therapy; human; hydrocele; hypertrophy; idiopathic disease; influenza; Korea; major clinical study; male; mucocutaneous lymph node syndrome; multicenter study; pharyngitis; pneumonia; post hoc analysis; preschool child; randomized controlled trial; rhinitis; rhinopharyngitis; short stature; thorax pain; tonsil disease; tonsillitis; upper respiratory tract infection; urticaria | English | Final | 2020 | 10.17925/ee.2020.16.1.54 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | ○ | Article | Efficacy and Safety of a Balanced Salt Solution Versus a 0.9% Saline Infusion for the Prevention of Contrast-Induced Acute Kidney Injury After contrast-Enhanced Computed Tomography | Rationale & Objective: We aimed to elucidate whether a balanced salt solution decreases the occurrence of contrast-induced acute kidney injury (CI-AKI) after contrast-enhanced computed tomography (CE-CT) as compared to 0.9% saline solution. Study Design: A randomized clinical trial. Setting & Participants: The study was performed in 14 tertiary hospitals in South Korea. Patients with estimated glomerular filtration rates (eGFRs) = 60 years or diabetes) who were undergoing scheduled CE-CT were included from December 2016 to December 2018. Intervention: An open-label intervention was performed. The study group received a balanced salt solution and the control group received 0.9% saline solution as prophylactic fluids for CE-CT. Outcomes: The primary outcome was CI-AKI, defined by creatinine level elevation >= 0.5 mg/dL or 25% from baseline within 48 to 72 hours after CE-CT. Secondary outcomes included AKI defined based on the KDIGO (Kidney Disease: Improving Global Outcomes) guideline, eGFR changes, death, or requiring dialysis within 6 months after CE-CT. Results: 493 patients received the study fluids. The control and study groups included 251 and 242 patients, respectively. The occurrence of CI-AKI in the study (10 [4.2%]) and control (17 [6.8%]) groups was not significantly different (P= 0.27). No significant difference was present for the secondary outcomes; AKI by the KDIGO definition (study: 19 [7.9%], control: 27 [10.8%]; P = 0.33), death/dialysis (study: 11 [4.7%], control: 9 [3.7%]; P = 0.74), and eGFR changes (study: 0.1 +/- 0.2 mg/dL, control: 0.3 +/- 2.8 mg/dL; P = 0.69). Limitations: This study failed to meet target enrollment. Conclusions: The risk for CI-AKI was similar after administration of a balanced salt solution and after use of 0.9% saline solution during CE-CT in higher-risk patients. | Park, Sehoon; Kim, Dong Ki; Jung, Hee-Yeon; Kim, Chan-Duck; Cho, Jang-Hee; Cha, Ran-hui; Jeong, Jong Cheol; Kim, Sejoong; Kim, Hyung-Jong; Ban, Tae Hyun; Ha Chung, Byung; Lee, Jung Pyo; Park, Jung Tak; Han, Seung Hyeok; Yoo, Tae-Hyun; Ryu, Dong-Ryeol; Moon, Sung Jin; Lee, Jung Eun; Huh, Wooseong; Kang, Ea Wha; Chang, Tae Ik; Joo, Kwon Wook | Armed Forces Capital Hosp, Dept Internal Med, Gyeonggi Do, South Korea; Seoul Natl Univ Hosp, Dept Internal Med, Seoul, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, Daegu, South Korea; Natl Med Ctr, Dept Internal Med, Seoul, South Korea; Seoul Natl Univ, Dept Internal Med, Bundang Hosp, Seoul, South Korea; CHA Univ, Bundang CHA Med Ctr, Dept Internal Med, Gyeonggi Do, South Korea; Catholic Univ Korea, Dept Internal Med, Seoul St Marys Hosp, Seoul, South Korea; Seoul Natl Univ, Dept Internal Med, Boramae Med Ctr, Seoul, South Korea; Yonsei Univ, Dept Internal Med, Coll Med, Seoul, South Korea; Ewha Womans Univ, Dept Internal Med, Mokdong Hosp, Seoul, South Korea; Catholic Kwandong Univ, Dept Internal Med, Int St Marys Hosp, Incheon, South Korea; Samsung Med Ctr, Dept Internal Med, Seoul, South Korea; Ilsan Hosp, Dept Internal Med, Natl Hlth Insurance Serv, Gyeonggi Do, South Korea | Kim, Dong Ki/J-5389-2012; Jung, Hee-Yeon/AFB-8578-2022; Kim, Hyungduk/CAH-5630-2022; Lee, Jun-Young/N-5963-2019; Lee, Jung-Seok/L-6826-2019; Han, Seung Hyeok/K-4559-2018; Joo, Kwon/J-5675-2012; Kim, Su Hyun/JPY-2079-2023; Han, Seung/K-4559-2018; Cho, Jang-hee/ABD-3534-2020; Kim, Sejoong/J-5356-2015 | 57210030734; 23479259100; 57196396467; 8558530700; 7403536291; 24385529700; 37761626800; 36068539400; 57191717726; 56119751700; 57201863822; 56028990400; 15036313100; 18233343300; 7101746143; 56669926200; 57199706198; 58034512300; 7006890932; 7201797000; 33067497300; 7101808967 | kidneyjang@gmail.com;junephro@gmail.com; | KIDNEY MEDICINE | 2590-0595 | 2 | 2 | 0.16 | 2025-06-25 | 2 | 2 | CORTICAL TISSUE PERFUSION; DOUBLE-BLIND CROSSOVER; BLOOD-FLOW-VELOCITY; CORONARY-ANGIOGRAPHY; INDUCED NEPHROPATHY; SODIUM-BICARBONATE; CHLORIDE; OUTCOMES | acute kidney injury; acute renal failure; balanced salt solution; computed tomography; Contrast-induced acute kidney injury; fluid; saline | balanced salt solution; creatinine; sodium chloride; aged; Article; computer assisted tomography; contrast enhancement; contrast induced nephropathy; controlled study; creatinine blood level; death; estimated glomerular filtration rate; female; fluid therapy; human; incidence; lung edema; major clinical study; male; multicenter study; open study; parallel design; randomized controlled trial; renal replacement therapy; South Korea; therapy effect; treatment outcome | English | 2020 | 2020 (MAR-APR) | 10.1016/j.xkme.2019.12.003 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Conference paper | Efficiently sharing remote computing resources for mobile devices | Computation offloading has been a trending technology in the last decade. Even though computation offloading provides great advantages in terms of performance and energy efficiency for mobile devices, it is inapplicable when an Internet connection is not present or unstable to provide remote executions. In this article, to address these limitations, we introduce a middleware system that can distribute CPU-intensive or commonly used functionality to mobile or edge/cloud devices. Our system enables peer-to-peer communications between nearby devices through a near communication technology. Moreover, one communication group can be connected to other groups, so that a mobile application can effectively utilize remote computing resources by extending its execution range. To realize our goal, we developed a proof-of-concept middleware system by employing a publish/subscribe communication pattern and the Wi-Fi Direct technology. Through various case studies, we demonstrate the effectiveness of the introduced system and easy development of complicated mobile applications in resource-constrained execution environments.

| ○ | Article | Electrolyte and acid-base imbalance in native calves with enteropathogenic diarrhea | Diarrhea is the most common cause of death in calves, and remains a major health challenge. Although there are many studies on the related pathogens, the understanding of the clinicopathological changes is limited. This study aimed to identify the pathogens and observe the clinicopathological changes in electrolytes and acute phase proteins (APPs) associated with diarrhea. Blood samples and fecal samples were collected from 141 calves for the determination of APPs, electrolyte and acid-base status and identification of enteropathogens, respectively. Single or co-infections with enteropathogens, including virus (bovine viral diarrhea virus, coronavirus, and rotavirus), Eimeria, Cryptosporidium, and Escherichia coli K99 were detected in both non-diarrheic and diarrheic calves. Levels of APPs such as serum amyloid A, haptoglobin and fibrinogen were comparable between diarrheic and non-diarrheic calves. Hypoglycemia, high blood urea, electrolytes and acid-base imbalance (hyponatremia, hypochloremia, and decreased bicarbonate), and strong ion difference (SID) acidosis showed a significant association in diarrheic calves (p < 0.01). Particularly, significant hyponatremia, bicarbonate loss, SID acidosis, hypoglycemia, and elevated blood urea nitrogen were found in rotavirus-infected calves. Monitoring the clinicopathological parameters of APPs and electrolyte levels could be vital in the clinical management of diarrheic calves. © 2020 Korean Society of Veterinary Science.
