| ○ | Article | Exploring biochemical bases of resistance to fruit fly infestation in sweet gourd crops | Female fruit flies, Bactrocera cucurbitae, thrust eggs into developing cucurbitaceous fruits, and larval feeding inside the fruits leads to damage. The biochemical properties of fruits can act against this insect pest. This study was carried out with 12 sweet gourd germplasm lines (Cucurbita moschata), namely BD 264, BD 265, BD 266, BD 268, BD 269, BD 274, BD 275, BD 277, BARI Mistikumra 1, BARI Mistikumra 2, Gazipur local line, and China line, to assess fruit fly abundance and infestation on germplasm lines, and to find out the relationship between the infestation of fruit flies and the biochemical properties of sweet gourd fruit. The lowest abundance of fruit flies was observed on BD 277, followed by BD 265, BD 264, and BD 275. The lowest number of maggots was found in BD 274, followed by BD 264, and BD 277. In terms of fruit infestation, BD 274 and BD 277 were identified as resistant lines; BD 264, BD 265, BD 266, BD 268, BD 269, and BD 275 were classified as moderately resistant lines; and BARI Mistikumra 1, BARI Mistikumra 2, Gazipur local line, and China line were categorized as susceptible lines. The biochemical properties of the germplasm lines varied significantly. The infestation of fruit fly had significant positive correlation with the moisture content of BD 266, BARI Mistikumra 1 and BARI Mistikumra 2, and the reducing sugar content of BARI Mistikumra 1 and BARI Mistikumra 2. © 2021, Penerbit Universiti Kebangsaan Malaysia.

| ○ | ○ | Article | Exploring correlation between OCO-2 XCO2 and DMSP/OLS nightlight imagery signature in four selected locations in India | This study identified the correlation between OCO-2 XCO2 signatures and night-time light (NTL) dynamics for four different landscapes in India: Megapolis (part of Mumbai), City (part of Raipur), Town (part of Dindigul), and Village (part of Balnoi). The data used for building the correlation were collected from Orbiting Carbon Observatory-2 (OCO-2) XCO2 and Defense Meteorological Satellite Program Operational Line Scanner's (DMSP/OLS) NTL datasets. The result of the study indicated that CO2 concentration is strongly related to NTL data. Megapolis part was found to exhibit higher values in both CO2 mean concentration (405.8 ppm) and NTL distribution level (41.5-pixel value), while the village part was low in both CO2 mean concentration (400.306 ppm) and NTL distribution level (4.4-pixel values). The city part of the data showed that the highest mean local R-2 (0.964) in Geographically Weighted Regression (GWR), while the village part recorded the lowest mean local R-2 (0.579) in the given data set. This study further emphasizes that the night light satellite imagery can be used as descriptors and proxies to calculate CO2 emission. | Matloob, Ambreen; Sarif, Md.

| ○ | Article | Extracorporeal Membrane Oxygenation for Coronavirus Disease 2019: Expert Recommendations from The Korean Society for Thoracic and Cardiovascular Surgery | Since the first reported case of coronavirus disease 2019 (COVID-19) in December 2019, the numbers of confirmed cases and deaths have continued to increase exponentially despite multi-factorial efforts. Although various attempts have been made to improve the level of evidence for extracorporeal membrane oxygenation (ECMO) treatment over the past 10 years, most experts still hesitate to take an active position on whether to apply ECMO in COVID-19 patients. Several ECMO management guidelines have been published recently, but they reflect some important differences from the Korean medical system and aspects of real-world medical practice in Korea. We aimed to find evidence on the efficacy of ECMO for COVID-19 patients by reviewing the published literature and to propose expert recommendations by analyzing the Korean COVID-19 ECMO registry data. © 2021 The Korean Society for Thoracic and Cardiovascular Surgery.

| ○ | Article | Fabrication and evaluation of hydrophobic metal stent using electron beam equipment | The objective of this study was to fabricate a novel hydrophobic stent for reducing restenosis by employing electron beam equipment. The stent was fabricated from a CoCr alloy tube by using a femtosecond laser and was treated with argon plasma. Subsequently, the stent’s surface specification changed from hydrophilic to hydrophobic. Application of the electron beam offers several advantages such as a short processing time, whole surface reforming, and enhancement of material properties. As the surface of the stent was rendered hydrophobic, it can provide equivalent or enhanced mechanical properties and greater functionality with a higher radial force at the extended stent in a blood vessel. The obtained results corresponding to the mechanical properties indicate that the contact angle increased to approximately 130o, and the radial force increased to approximately 3 N. Furthermore, cell culture experiments were conducted for verifying whether cells were cultured on the surface-modified CoCr surface. Based on the obtained results, it is believed that an effective reduction in the restenosis of inserted vascular stents is possible. © 2021, Korean Sensors Society.

| ○ | ○ | Article | Fabrication of 3D Multilayered Microfluidic Channel Using Fluorinated Ethylene Propylene Nanoparticle Dispersion | In this study, fluorinated ethylene propylene (FEP) nanoparticle as an adhesive for fabricating a threedimensional multilayered microfluidic device was studied. The formation of evenly distributed FEP nanoparticles layer with 3 mu m in thickness on substrates was achieved by simple spin coating of FEP dispersion solution at 1500 rpm for 30 s. It is confirmed that FEP nanoparticles transformed into a hydrophobic thin film after thermal treatment at 300 degrees C for 1 hour, and fabricated polyimide film-based microfluidic device using FEP nanoparticle was endured pressure up to 2250 psi. Finally, a three-dimensional multilayered microfluidic device composed of 16 microreactors, which are difficult to fabricate with conventional photolithography, was successfully realized by simple one-step alignment of FEP coated nine polyimide films. The developed three-dimensional multilayered microfluidic device has the potential to be a powerful tool such as high-throughput screening, mass production, parallelization, and large-scale microfluidic integration for various applications in chemistry and biology. | Min, Kyoung-Ik | Kyungpook Natl Univ, Biomed Convergence Sci & Technol, 80 Daehakro, Daegu 41566, South Korea | 25028141900 | kimin@knu.ac.kr; | KOREAN CHEMICAL ENGINEERING RESEARCH | KOREAN CHEM ENG RES | 0304-128X | 2233-9558 | 59 | 4 | ESCI | ENGINEERING, CHEMICAL | 2021 | N/A | 0.14 | 2025-07-30 | 2 | 2 | Fluoropolymer; Fluorinated ethylene propylene; Microfluidics; Three-dimensional microchannel; Polyimide film | POLY(DIMETHYLSILOXANE) | Fluorinated ethylene propylene; Fluoropolymer; Microfluidics; Polyimide film; Three-dimensional microchannel | Korean | 2021 | 2021-11 | 10.9713/kcer.2021.59.4.639 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Fabrication of superabsorbent biogel from carboxymethyl cellulose; [카르복시메틸셀룰로오스 기반의 고흡수성 바이오 겔 제조] | Superabsorbent polymer (SAP) is a three-dimensional network polymer with a high capacity of uptaking a water-containing solution. Carboxymethyl cellulose (CMC) has been extensively used as an absorbent polymer; however, its water-holding properties are inferior compared with that of SAP. In this study, the fabrication of bio-gels from CMC crosslinked with acrylic acid has been evaluated to improve saline solution-holding capacities by three production routes. The swelling capacity of the biogel fabricated by a sequential process of brief homogenization treatment on the crosslinked reactant and addition of CMC powders was significantly increased; its initial absorption rate was comparable to that of the commercial SAP. © 2021 Korean Technical Assoc. of the Pulp and Paper Industry.

| ○ | Article | Fabrication of surface-enhanced Raman scattering substrate using black silicon layer manufactured through reactive ion etching | In this study, Ag was deposited to investigate its applicability as a surface-enhanced Raman scattering substrate after forming a grasstype black silicon structure through maskless reactive ion etching. Grass-structured black silicon with heights of 2–7 μm was formed at radio-frequency (RF) power of 150–170W. The process pressure was 250mTorr, the O2/SF6 gas ratio was 15/37.5, and the processing time was 10–20 min. When the processing time was increased by more than 20 min, the self-masking of SixOyFz did not occur, and the black silicon structure was therefore not formed. Raman response characteristics were measured based on the Ag thickness deposited on a black silicon substrate. As the Ag thickness increased, the characteristic peak intensity increased. When the Ag thickness deposited on the black silicon substrate increased from 40 to 80 nm, the Raman response intensity at a Raman wavelength of 1507/cm increased from 8.2 × 103 to 25 × 103 cps. When the Ag thickness was 150 nm, the increase declined to 30 × 103 cps and showed a saturation tendency. When the RF power increased from 150 to 170 W, the response intensity at a 1507/cm Raman wavelength slightly increased from 30 × 103 to 33 × 103 cps. However, when the RF power was 200 W, the Raman response intensity decreased significantly to 6.2 × 103 cps. © 2023 The Authors. | Kim, Hyeong Ju; Kim, Bonghwan; Lee, Dongin; Lee, Bong-Hee; Cho, Chanseob | School of Electronics Engineering, Kyungpook National University, Daegu, 41566, South Korea; School of Electronic and Electrical Engineering, Daegu Catholic University, Gyeongsangbuk-do, 38430, South Korea; Department of Information and Communication Engineering, Yeungnam University, Gyeongsangbuk-do, 38541, South Korea; Department of Steel Industry, Pohang University, Phohang, 37655, South Korea; School of Electronics Engineering, Kyungpook National University, Daegu, 41566, South Korea | 58530129200; 24833360700; 55668477600; 58569511200; 24471515900 | chocs@knu.ac.kr; | Journal of Sensor Science and Technology | 1225-5475 | 30 | 4 | 0.27 | 2025-07-30 | 3 | Black silicon; Raman response; RIE; Surface-enhanced Raman scattering (SERS) | Korean | Final | 2021 | 10.46670/jsst.2021.30.4.267 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Fabrication of thermal conductive adhesive using Ni graphite core-shell and application to LED lighting | High-power light-emitting diode (LED) lighting exhibits excessive heat generation owing to the need to drive an LED chip, development of heat dissipation technology is required to resolve that problem. Until now, most of the studies on heat dissipation in LED lighting have been limited to research on heat dissipation of the chip itself and research into the manufacture of heat sinks. However, a solution in a new direction is required owing to the quantity of heat generated from dense LED chips found in high-power LED lighting or in situations where the space for the lighting is limited owing to its location. In this research, heat dissipation characteristics were improved by adding a Ni-graphite core-shell (Ni-GCS) to the thermally conductive adhesive used to bond the LED chip's substrate to the heat sink in high-power LED lighting applications. Ni-GCS was synthesized through thermal chemical vaper deposition (thermal-CVD), and the Ni nanoparticles were confirmed are to be wrapped by a graphite layer. When high-power LED lighting using the novel thermally conductive adhesive was driven over a long period of time, improved heat dissipation characteristics were observed when the properties of the thermal changes were analyzed. © This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. | Kim, Chang-Duk; Jo, Younjung; Truong, Nguyen Tam Nguyen | Department of Physics, Kyungpook National University, Daegu, 41566, South Korea; Department of Physics, Kyungpook National University, Daegu, 41566, South Korea; School of Chemical Engineering, Yeungnam University, Gyeongsan, 38541, South Korea | 57200982445; 13502586500; 25958384000 | duks@knu.ac.kr;jophy@knu.ac.kr; | New Physics: Sae Mulli | 0374-4914 | 71 | 5 | 0.07 | 2025-07-30 | 1 | Core-shell; Graphite; Heat radiation; LED lighting; Thermally conductive adhesive | Korean | Final | 2021 | 10.3938/npsm.71.422 | 바로가기 | 바로가기 | ||||||||||||||||

| ○ | Article | Fabrication of tungsten micro needle arrays using laser beam machining | Micro needle arrays have been widely used within medical contexts, such as for drug delivery and nervous electrodes, and its fabrication methods have attracted attention recently. This paper describes a novel fabrication method for micro needle arrays on a tungsten metal plate using only laser beam machining. Tungsten material was ablated as combining laser beam scanning path to control needle structure. Overlapping laser beams from the combined scanning path causes thermal accumulation phenomena which removes the material. In this paper, controlling laser scanning path (Line Interval, Line Space, Number of Lines) and machining conditions (Power, Number of Scan), and the changing length and pitch of the micro needles were measured through SEM. Moreover, the piercing force for application in drug delivery and nervous electrodes was measured with a load cell system. © 2021 Korean Society for Precision Engineeing.

| ○ | Article | Facile acetylation of woody biomass using a glycol ether solvent | This study was aimed at modifying the surface of cellulose. An acetylated sample was prepared through a simpler process compared with conventional acetylation, and its characteristics were analyzed. The particle size of the sample was approximately 0.5-1.0 mm; the particle size of the wood flour decreased as the amount of acetic anhydride was increased. Further, the yield of the acetylated sample increased with the acetic anhydride content, and the lowest yield was obtained when the acetic acid and acetic anhydride content were the same. Additionally, the residual lignin content decreased as the acetic acid content increased. The degree of acetylation of the sample was confirmed through the peaks of the carbonyl, acetyl, and hydroxyl groups in the IR spectra. The degree of substitution (DS) of the facile acetylated sample increased rapidly with the addition of acetic anhydride. © 2021 Korean Technical Assoc. of the Pulp and Paper Industry.

| ○ | ○ | Article | Facile Synthesis of Gold Nanoparticles Using Tyrosine-Rich Peptide and Its Applications to Catalytic Reduction of 4-Nitrophenol | In this study, we studied a facile method for the synthesis of stable and nearly spherical gold nanoparticles using a tyrosine-rich peptide, Tyr-Tyr-Gly-Tyr-Tyr (YYGYY), as both the reducing and capping agent. The peptide coated spherical and polycrystalline gold nanoparticles with diameters from 3 to 15 nm were successfully synthesized by varying the concentration of the peptide and metal precursor under UV irradiation. The nanoparticles were then characterized by transmission electron microscopy (TEM), UV-Vis spectroscopy, scanning transmission electron microscopy-energy dispersive X-ray spectroscopy (STEM-EDS), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD). Furthermore, the catalytic activity of gold nanoparticles was confirmed by the reduction of 4-nitrophenol to 4-aminophenol, in which the catalytic reaction rate constant was 7.3 x 10(-3) s(-1). | Hur, Yun-Mi; Min, Kyoung-Ik | Kyungpook Natl Univ, Biomed Convergence Sci & Technol, Daegu 41566, South Korea | 57222251131; 25028141900 | huryunmi001@gmail.com;kimin@knu.ac.kr;kimin@gmail.com; | APPLIED CHEMISTRY FOR ENGINEERING | APPL CHEM ENG | 1225-0112 | 1228-4505 | 32 | 1 | ESCI | ENGINEERING, CHEMICAL | 2021 | N/A | 0.06 | 2025-07-30 | 1 | 1 | Peptide; Tyrosine; Gold nanoparticle; Green synthesis; 4-nitrophenol | METAL NANOPARTICLES | 4-nitrophenol; Gold nanoparticle; Green synthesis; Peptide; Tyrosine | Korean | 2021 | 2021-02 | 10.14478/ace.2020.1099 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Factors Affecting Burnout among Tertiary Hospital Nurses during the COVID-19 Outbreak | Purpose: The aim of this study was to determine burnout and its related factors among nurses working at a tertiary hospital, who had experienced caring for patients with confirmed and suspected coronavirus disease 2019 (COVID-19), including those with severe and critical conditions during the outbreak. Methods: Responses of 129 nurses, who worked in a tertiary hospital in Daegu, which was designated as a special control area for infectious disease in Korea, were analyzed. Data were collected from November 1, 2020 to December 14, 2020 using self-report questionnaires. Analysis was performed using t-test, one-way ANOVA, Pearson correlation coefficients, and stepwise multiple regression. Results: Burnout did not show any statistically significant differences in age, sex, marital status, total length of clinical experience, and the department at the time of caring for COVID-19 patients. Compassion fatigue, stress, depression, and anxiety were positively related with burnout, and compassion satisfaction was negatively related with burnout. In regression analysis, compassion satisfaction, compassion fatigue, and stress were confirmed as the predictive factors of burnout. Conclusion: The study results suggest that compassion satisfaction, compassion fatigue, and stress could play an important role in reducing burnout among tertiary hospital nurses during infectious disease outbreaks. © 2021 The Korean Academy of Psychiatric and Mental Health Nursing. | Kim, Geun-Hee; You, Jun Ok; Lee, Mira; Choi, Yunju; Lee, Yoon Mi; Shin, Ji Hye | Nursing Education Team, Kyungpook National University Hospital, Daegu, South Korea; Division of Nursing Education and Administration, Kyungpook National University Hospital, Daegu, South Korea; Nursing Education Team, Kyungpook National University Hospital, Daegu, South Korea; Hemodialysis Unit, Kyungpook National University Hospital, Daegu, South Korea; Nursing Education Team, Kyungpook National University Hospital, Daegu, South Korea; Nursing Education Team, Kyungpook National University Hospital, Daegu, South Korea | 58731281800; 57488433000; 57488433100; 57488540000; 57224358209; 57224782602 | youmetpig@hanmail.net; | Journal of Korean Academy of Psychiatric and Mental Health Nursing | 1225-8482 | 30 | 4 | 0.6 | 2025-07-30 | 6 | Burnout; COVID-19; Nurses; Tertiary hospital | Korean | Final | 2021 | 10.12934/jkpmhn.2021.30.4.390 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Factors affecting successful esophageal foreign body removal using a Foley catheter in pediatric patients | Objective This study aimed to determine the factors that affect successful esophageal foreign body (FB) removal using a Foley catheter and to identify methods to increase the success rate. Methods In this retrospective, cross-sectional study, we included pediatric patients who presented with esophageal FB impaction that was removed using a Foley catheter in the emergency departments of tertiary care and academic hospitals. We analyzed the effect of the patients' age, sex, and symptoms; FB type, size, and location; Foley catheter size; complications during FB removal; duration between FB ingestion and removal; operator's years of training; sedation; success rate of FB removal; endoscopy; and patient's posture during FB removal on the success of Foley catheter-based FB removal. Results Of the 43 patients we enrolled, Foley catheter-based FB removal was successful in 81.4% (35/43) but failed in 18.6% (8/43) of patients; no FB-removal-related complications were reported. There was no significant association between the success rate of Foley catheter-based FB removal and any study variable. A higher number of years in training tended to increase the success rate of Foley catheter-based FB removal, although statistical significance was not achieved. Conclusion Children's esophageal FB removal is a practical challenge in the emergency rooms, and using a Foley catheter is associated with a high success rate of the removal and low occurrence of complications. In this study, no single variable was found correlated with the success rate of Foley catheter-based esophageal FB removal in pediatric patients, which may indicate multiple variables interacting with one another to affect the success rate. | Lim, Donghoon; Kim, Jong Kun; Kim, Yun Jeong; Cho, Yeon Joo; Cho, Jae Wan; Park, Jungbae; Choe, Jae Young; Choe, Byung-Ho | Kyungpook Natl Univ, Dept Emergency Med, Sch Med, 130 Dongdeok Ro, Daegu, South Korea; Kyungpook Natl Univ, Dept Pediat, Sch Med, Daegu, South Korea | Park, Jae Yong/ISS-5916-2023; Choe, Byung-Ho/KSM-6251-2024; Kim, Joo/JAZ-0897-2023 | 57223202585; 55915816900; 57202340666; 57219251787; 7403536065; 57189030435; 57023107400; 57574977300 | cjy@knu.ac.kr; | CLINICAL AND EXPERIMENTAL EMERGENCY MEDICINE | CLIN EXP EMERG MED | 2383-4625 | 8 | 1 | ESCI | EMERGENCY MEDICINE | 2021 | N/A | 0.16 | 2025-07-30 | 1 | 1 | Foreign bodies; Foley catheterization; Endoscopy; Esophagus; Child | Child; Endoscopy; Esophagus; Foley catheterization; Foreign bodies | ketamine; midazolam; adolescent; adult; aged; Article; case report; catheter removal; catheterization; child; clinical article; computer assisted tomography; cross-sectional study; endoscopy; esophagus foreign body; female; human; male; preschool child; school child; sedation; treatment failure; very elderly; young adult | English | 2021 | 2021-03 | 10.15441/ceem.20.070 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
