| ○ | ○ | Article | Synthesis and Characterization of FeNi-based Composite Powder from the Mixture of Fe-based Amorphous Powders and Crystalline Ni powders | Fe-Ni alloys have attracted interest as important magnetic alloys without rare-earth (RE) elements, which exhibit a wide variety of magnetic properties depending on the atomic ratios of Fe and Ni. Here, we attempted to synthesize Fe-Ni magnetic materials using a Fe based amorphous alloy precursor that is thermodynamically metastable and has more open atomic packing structure than crystalline alloys. High energy ball milling was applied to promote the formation of various Fe-Ni phases using mixtures of the amorphous precursor powder and 10-50% crystalline Ni powder. The as-milled composite powders as well as the composite powders annealed at 673 K were analyzed by X-ray diffractometer, differential scanning calorimeter, scanning electron microscope, and vibrating sample magnetometer to investigate their magnetic properties in terms of phase transformation behavior of the composite powders. | Kim, Jinyoung; Hwang, Jiyong; Yi, Seonghoon | Kyungpook Natl Univ, Dept Mat Sci & Met Engn, Daegu 41566, South Korea | ; Yi, Seonghoon/HGC-6912-2022 | 58384365900; 57190225749; 14008383000 | yish@knu.ac.kr; | JOURNAL OF MAGNETICS | J MAGN | 1226-1750 | 2233-6656 | 26 | 3 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2021 | 0.551 | 96.4 | 0.08 | 2025-07-30 | 1 | 1 | FeNi-based composites; mechanical alloying; amorphous alloy; phase transformation; magnetic property | MAGNETIC-PROPERTIES; DIFFUSION | Amorphous alloy; FeNi-based composites; Magnetic property; Mechanical alloying; Phase transformation | English | 2021 | 2021-09 | 10.4283/jmag.2021.26.3.322 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Low-Power Fast Partial Firmware Update Technique of On-Chip Flash Memory for Reliable Embedded IoT Microcontroller | IoT devices operate with a battery and have embedded firmware in flash memory. If the embedded firmware is not kept up to date, there is a possibility of problems that cannot be linked with other IoT networks, so it is necessary to maintain the latest firmware with frequent updates. However, because firmware updates require developers and equipment, they consume manpower and time. Additionally, because the device must be active during the update, a low-power operation is not possible due to frequent flash memory access. In addition, if an unexpected interruption occurs during an update, the device is unavailable and requires a reliable update. Therefore, this paper aims to improve the reliability of updates and low-power operation by proposing a technique of performing firmware updates at high speed. In this paper, we propose a technique to update only a part of the firmware stored in nonvolatile flash memory without pre-processing to generate delta files. The firmware is divided into function blocks, and their addresses are collectively managed in a separate area called a function map. When updating the firmware, only the new function block to be updated is transmitted from the host downloader, and the boot-loader proceeds with the update using the function block stored in the flash memory. Instead of transmitting the entire new firmware and writing it in the memory, using only function block reduces the amount of resources required for updating. Function-blocks can be called indirectly through a function map, so that the update can be completed by modifying only the function map regardless of the physical location. Our evaluation results show that the proposed technique effectively reduces the time cost, energy consumption, and additional memory usage overhead that can occur when updating firmware. | Kwon, Jisu; Seok, Moon Gi; Park, Daejin | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea; Nanyang Technol Univ, Sch Comp Sci & Engn, Singapore, Singapore | 57215531728; 36683242700; 55463943600 | boltanut@knu.ac.kr; | IEICE TRANSACTIONS ON ELECTRONICS | IEICE T ELECTRON | 0916-8524 | 1745-1353 | E104C | 6 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2021 | 0.477 | 96.9 | 0.44 | 2025-07-30 | 5 | 6 | bootloader; flash memory; firmware update; function block; function map | CODE | Bootloader; Firmware update; Flash memory; Function block; Function map | Energy utilization; Firmware; Internet of things; Microcontrollers; Embedded firmwares; Evaluation results; Firmware updates; Function Block; Low-power operation; Nonvolatile flash memory; Physical locations; Reliable updates; Flash memory | English | 2021 | 2021-06 | 10.1587/transele.2020lhp0001 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Controlling Internal Pore Structure of Porous Carbon Nanofibers Based on the Miscibility between Polyacrylonitrile Matrix and Sacrificial Polymers | Porous carbon nanofibers were prepared via electrospinning of polyacrylonitrile (PAN)-based blend solutions and effects of miscibility of the blended polymers on pore structure were investigated. Two sacrificial polymers, poly(vinylidene fluoride) (PVDF) and poly(styrene-co-acrylonitrile) (SAN), were chosen as a sacrificial component to yield porosity after carbonization. The miscibility of PAN with each sacrificial polymer was evaluated both theoretically and empirically. Analyzing solubility parameters revealed that PVDF had higher chemical affinity with PAN due to dipole-dipole interaction than SAN. Lower value of Flory-Huggins interaction parameter of PAN with PVDF (0.52) than with SAN (1.19) quantitatively confirmed the better miscibility of PAN-PVDF. In dynamic mechanical analysis of PAN/ PVDF blend films, individual loss tangent (tan delta) peaks (i.e., glass transition peak) for PAN and PVDF were observed but they were shifted to each other, indicating partial miscibility. In PAN/SAN films, however, the peak shift of PAN was negligible. These results coincided well with the theoretical analysis. After carbonization, the blend nanofibers exhibited high porosity with different pore structures; elongated shape for PVDF and round shape for SAN system. The pore structure discrepancy in the two systems was ascribed to the miscibility difference of each sacrificial polymer with PAN matrix. | Hwang, Hyunmin; Chae, Dong Wook; Eom, Youngho | Pukyong Natl Univ, Dept Polymer Engn, Busan 48513, South Korea; LG Household & Hlth Care, Seoul 07785, South Korea; Kyungpook Natl Univ, Dept Text Engn, Sangju 37224, South Korea | Eom, Youngho/U-6387-2019 | 57339439800; 7006246752; 56108103900 | eomyh@pknu.ac.kr; | POLYMER-KOREA | POLYM-KOREA | 0379-153X | 2234-8077 | 45 | 2 | SCIE | POLYMER SCIENCE | 2021 | 0.473 | 97.2 | 0.07 | 2025-07-30 | 1 | 1 | polyacrylonitrile; porous carbon nanofibers; electrospinning; solubility parameter; Flory-Huggins interaction parameter | SOLUBILITY PARAMETER; ELECTROSPUN; FIBERS; FABRICATION; SIZE | Electrospinning; Flory-Huggins interaction parameter; Polyacrylonitrile; Porous carbon nanofibers; Solubility parameter | Korean | 2021 | 2021-03 | 10.7317/pk.2021.45.2.228 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Critical Fluorescence Enhancement of a Polydiphenylacetylene Derivative through Thermally Induced Phase Separation | Phase change and fluorescence properties of the polydiphenylacetylene derivative, poly[1-phenyl-2-(p-trimethysilyl) phenylacetylene] (PTMSDPA), were investigated according to the thermally induced phase separation (TIPS) method. 1,4-dioxane was selected as the theta solvent from solvents having solubility parameters similar to that of the polymer, and the phase diagram of the solution of PTMSDPA/1,4-dioxane was derived using the cloud-point method. A critical point appeared at a concentration of 0.88x10(-2) M and a temperature of 51.6 degrees C as the theta condition. During the cooling process, a significant fluorescence enhancement occurred near the critical point, because collision quenching and vibration relaxation in the polymer chain, which causes non-radiative emission decay, are restrained by the abrupt phase separation between the polymer and the solvent. This study provides a tentative method for producing highly fluorescent nanoparticles and microporous membranes by applying TIPS to fluorescent conjugated polymers. | Park, Hyosang; Kim, Heesang; Kwak, Giseop | Kyungpook Natl Univ, Sch Appl Chem Engn Major Polymer Sci & Engn, 1370 Sankyuk Dong, Deagu 41566, South Korea | 57195036789; 57226091356; 17137322300 | gkwak@knu.ac.kr; | POLYMER-KOREA | POLYM-KOREA | 0379-153X | 2234-8077 | 45 | 4 | SCIE | POLYMER SCIENCE | 2021 | 0.473 | 97.2 | 0 | 2025-07-30 | 0 | 0 | thermally induced phase separation; polydiphenylacetylene; phase diagram; theta solvent; fluorescence emission | CONJUGATED POLYMER | Fluorescence emission; Phase diagram; Polydiphenylacetylene; Thermally induced phase separation; Theta solvent | Korean | 2021 | 2021-07 | 10.7317/pk.2021.45.4.628 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Development of Sprayable Gelatin Hydrogel Wound Dressings Using Enzymatic Crosslinking Reaction | The gelatin hydrogel modified with tyramine (Gel-Tyr) was prepared an enzymatic crosslinking reaction to develop a sprayable wound dressing that is easy to use and hygienic on broad and complicate wound area with biocompatibility, wound healing ability, and comfortable wearing. The substitution rate of Gel-Tyr was calculated through H-1 NMR. And the gelation time according to the concentration of gelatin, horseradish peroxidase (HRP) and H2O2, rheological properties, swelling ratio, biodegradation behavior, in vitro cytotoxicity, cell viability was evaluated. The hydrogel with rapid gelation rate and optimum performance as a wound dressing was selected as a sample prepared with a compound concentration of Gel-Tyr 3 wt%, HRP 3.50 units/mL, and H2O2 0.2 mu L/mL. In the in vivo full-thickness wound model animal experiment and histological evaluation, the Gel-Tyr hydrogel showed an accelerated wound healing rate and dermal regeneration compared to the control group. It is expected to be used as a sprayable wound dressing in medical treatment, conveniently. | Kim, Gwijae; Ko, Young-Gwang; Lee, Hyeyoung; Chung, Ho Yun; Kwon, Oh Hyeong | Kumoh Natl Inst Technol, Dept Polymer Sci & Engn, Gumi 39177, Gyeongbuk, South Korea; Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, CMRI, Daegu 41944, South Korea | 57449611500; 35812149900; 57449395300; 7404007181; 55665582200 | ohkwon@kumoh.ac.kr; | POLYMER-KOREA | POLYM-KOREA | 0379-153X | 2234-8077 | 45 | 4 | SCIE | POLYMER SCIENCE | 2021 | 0.473 | 97.2 | 0 | 2025-07-30 | 0 | 0 | gelatin; tyramine; sprayable hydrogel; enzymatic crosslinking; wound dressing | TISSUE; CLASSIFICATION; PEROXIDASE | Enzymatic crosslinking; Gelatin; Sprayable hydrogel; Tyramine; Wound dressing | Korean | 2021 | 2021-07 | 10.7317/pk.2021.45.4.610 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effect of Commingled Yarn Type on the Manufacturing of Glass Fiber/Polypropylene Composite Prepreg | Glass fiber/polypropylene (GF/PP) composite prepregs were produced using different types of commingled yarns with different weave patterns. The commingled yarn used in this study was prepared using covering and air textured methods and the prepared commingled yarns were woven into two different weave patterns, plain and twill. The results show the effect of the commingling method and weave pattern on impregnation and alignment of GF in the composite prepregs due to the flow of the highly viscous molten PP resins. The mechanical properties (tensile strength, puncture impact properties, and Izod pendulum impact resistance) of the prepared composite prepregs were also evaluated. The results of this study show that the best tensile and impact resistance properties of composite prepreg is achieved using fabrics with a twill weave pattern made from air textured yarn (ATY) commingled yarns, which ensures the uniformity and alignments of the GF yarns in the composite. | Cho, Jinwon; Park, Jaehyeung | SHIN HEUNG, Daegu 41756, South Korea; Kyungpook Natl Univ, Dept Biofibers & Mat Sci, Daegu 41566, South Korea | 57703600800; 55566554000 | parkj@knu.ac.kr; | POLYMER-KOREA | POLYM-KOREA | 0379-153X | 2234-8077 | 45 | 3 | SCIE | POLYMER SCIENCE | 2021 | 0.473 | 97.2 | 0.29 | 2025-07-30 | 4 | 4 | commingled yarn; prepreg; glass fiber; polypropylene | THERMOPLASTIC COMPOSITES; CONSOLIDATION | Commingled yarn; Glass fiber; Polypropylene; Prepreg | English | 2021 | 2021-05 | 10.7317/pk.2021.45.3.414 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | Article | EVALUATION OF ANTIMICROBIAL, ANTIOXIDANT AND ENZYME INHIBITORY POTENTIAL OF FIXED OIL EXTRACTED FROM STEM BARK OF Acacia stenophylla | The current research was planned to determine the antimicrobial, antioxidant and enzyme inhibitory activity of fixed oil extracted from stem bark of Acacia stenophylla. Antimicrobial activities were determined by disc-diffusion and macro dilution methods. The results revealed that maximum zone of inhibition (bacteria and fungi) was measured by fixed oil against 12 mm and 5 mm, respectively. MIC values recorded by fixed oil were 0.5 mg/ml, 1.0 mg/ml, 2.0 mg/ml, 4.0 mg/ml and 8.0 mg/ml against different bacterial and fungal strains tested. Acetylcholinesterease and lipooxygenase inhibitory activity were measured by spectrophotometric methods. Fixed oil of Acacia stenophylla inhibited acetylcholinesterase by 247.1 mg/ml (IC50). Similarly, antioxidant potential of fixed oil was measured by two different models, i.e ABTS radical scavenging and ferric reducing/antioxidant power (FRAP) assay. The reduction in ABTS radical scavenging activity depended on the concentration of the extract. Maximum percent inhibition was shown by fixed oil at 800 mu g/ml. In case of ferric reducing/antioxidant power assay, plant sample showed inhibition of 671.3 mu g/ml. It is concluded that fixed oil of Acacia stenophylla has strong antimicrobial, enzyme inhibitory and antioxidant potential. | Khan, Nadia; Iqbal, Arshad; Rehman, Khushnood Ur; Hamayun, Muhammad; Shah, Farooq; Iqbal, Amjad; Hussain, Anwar; Ahmad, Jamshaid; Lee, In-Jung | Islamia Coll Peshawar, Dept Bot, Peshawar, Pakistan; Abdul Wali Khan Univ Mardan, Dept Bot, Mardan, Pakistan; Abdul Wali Khan Univ Mardan, Dept Agron, Mardan, Pakistan; Abdul Wali Khan Univ Mardan, Dept Food Sci & Technol, Mardan, Pakistan; Univ Peshawar, Ctr Biotechnol & Microbiol COBAM, Peshawar, Pakistan; Kyungpook Natl Univ, Sch Appl Biosci, Daegu, South Korea | Lee, In-Jung/GLS-0432-2022; Ahmad, Jamshaid/AAD-2941-2021; Hussain, Anwar/N-1605-2019; Hamayun, Muhammad/B-1694-2010; Iqbal, Dr-Arshad/LMO-6302-2024; Ur Rehman, Khushnood/AAZ-1451-2021; Iqbal, Amjad/E-2010-2014; Shah, Farooq/GVT-6352-2022 | ijlee@knu.ac.kr; | FRESENIUS ENVIRONMENTAL BULLETIN | FRESEN ENVIRON BULL | 1018-4619 | 1610-2304 | 30 | 9 | SCIE | ENVIRONMENTAL SCIENCES | 2021 | 0.618 | 97.3 | 1 | Acacia stenophylla; Fixed oil extraction; Antimicrobial; Antioxidant; ACE inhibition | CASSIA-NEMOPHILA PODS; SEED EXUDATE; COMPONENTS; CULTIVARS; DIVERSITY; PLANTS; SALT | English | 2021 | 2021 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Article | Tight Upper Bound on the Bit Error Rate of Convolutional Codes over Correlated Nakagami-m Fading Channels | In this letter, we investigate tight analytical and asymptotic upper bounds for bit error rate (BER) of constitutional codes over exponentially correlated Nakagami-m fading channels. Specifically, we derive the BER expression depending on an exact closed-form formula for pairwise error event probabilities (PEEP). Moreover, the corresponding asymptotic analysis in high signal-to-noise ratio (SNR) regime is also explored, which is verified via numerical results. This allows us to have explicit insights on the achievable coding gain and diversity order. | Jeong, Seongah; Kang, Jinkyu; Lee, Hoojin | Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea; Myongji Univ, Dept Informat & Commun Engn, Gyeonggi Do, South Korea; Hansung Univ, Div IT Convergence Engn, Seoul, South Korea | ; Jeong, Seongah/ABW-7285-2022; Kang, Joonhyuk/C-1771-2011; Jeong, Seongah/I-2863-2017 | 55210226900; 56283062100; 57215913990 | seongah@knu.ac.kr;jkkang@mju.ac.kr;hjlee@hansung.ac.kr; | IEICE TRANSACTIONS ON FUNDAMENTALS OF ELECTRONICS COMMUNICATIONS AND COMPUTER SCIENCES | IEICE T FUND ELECTR | 0916-8508 | 1745-1337 | E104A | 8 | SCIE | COMPUTER SCIENCE, HARDWARE & ARCHITECTURE;COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC | 2021 | 0.423 | 97.3 | 0 | 2025-07-30 | 0 | 0 | asymptotic analysis; convolutional codes; linear block codes; bit error rate (BER); pairwise error event probabilities (PEEP); Nakagami-m fading channels; performance analysis | Asymptotic analysis; Bit error rate (BER); Convolutional codes; Linear block codes; Nakagamim fading channels; Pairwise error event probabilities (PEEP); Performance analysis | Asymptotic analysis; Bit error rate; Convolutional codes; Errors; Fading channels; BER expression; Closed-form formulae; Coding gains; Correlated nakagami-m fading channels; Diversity order; Error events; High signalto-noise ratios (SNR); Numerical results; Signal to noise ratio | English | 2021 | 2021-08 | 10.1587/transfun.2020eal2106 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Usage Log-Based Testing of Embedded Software and Identification of Dependencies among Environmental Components | Embedded software often interacts with multiple inputs from various sensors whose dependency is often complex or partially known to developers. With incomplete information on dependency, testing is likely to be insufficient in detecting errors. We propose a method to enhance testing coverage of embedded software by identifying subtle and often neglected dependencies using information contained in usage log. Usage log, traditionally used primarily for investigative purpose following accidents, can also make useful contribution during testing of embedded software. Our approach relies on first individually developing behavioral model for each environmental input, performing compositional analysis while identifying feasible but untested dependencies from usage log, and generating additional test cases that correspond to untested or insufficiently tested dependencies. Experimental evaluation was performed on an Android application named Gravity Screen as well as an Arduino-based wearable glove app. Whereas conventional CTM-based testing technique achieved average branch coverage of 26% and 68% on these applications, respectively, proposed technique achieved 100% coverage in both. | Jeong, Sooyong; Cha, Sungdeok; Lee, Woo Jin | Kyungpook Natl Univ, Daegu 41566, South Korea; Korea Univ, Seoul 02841, South Korea | 55980660400; 7201865525; 55682653854 | kyo1363@naver.com;woojin@knu.ac.kr; | IEICE TRANSACTIONS ON INFORMATION AND SYSTEMS | IEICE T INF SYST | 1745-1361 | E104D | 11 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;COMPUTER SCIENCE, SOFTWARE ENGINEERING | 2021 | 0.695 | 97.3 | 0 | 2025-07-30 | 0 | 0 | embedded software testing; environmental modeling; test coverage | Embedded software testing; Environmental modeling; Test coverage | Embedded software; Petroleum reservoir evaluation; Well testing; Android applications; Behavioral model; Compositional analysis; Embedded software testing; Environmental model; Experimental evaluation; Incomplete information; Multiple inputs; Test case; Test-coverage; Software testing | English | 2021 | 2021-11 | 10.1587/transinf.2021edl8042 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Association of beverage intake with urinary Na and K excretion among Korean young adults | Objective: Some evidence has suggested that beverage consumption may be associated with dietary sodium (Na) and potassium (K) intake. The purpose of this study was to investigate the relationship between beverage consumption and urinary Na and K excretion among Korean young adults, who have the highest beverage intake. Materials and methods: This cross-sectional study analyzed data from 256 healthy adults aged 20 - 39 years in South Korea. Participants' beverage intake was assessed using 24-hour dietary recall interviews. In addition, 24-hour urinary Na and K excretion values were analyzed from collected 24 hour urine samples. Dietary surveys and 24 hour urine collections were repeated 3 days later. Results: The total daily beverage intake of the young adults was 370.4 g: 117.2 g for alcoholic beverages, 96.6 g for caffeinated beverages, 80.4 g for milk beverages, and 76.0 g for sweet beverages. The urinary Na/K excretion of sugary-beverage consumers was significantly higher than that of non consumers (p < 0.01). Total beverage intake was not correlated with urinary Na and K excretion. However, the consumption of milk beverages with regard to total subjects and caffeinated beverages in male subjects were significantly and negatively correlated with urinary Na/K excretion (p < 0.01, p < 0.05). Conclusion: In Korean young adults, while total beverage intake was not associated with urinary Na and K excretion, milk beverage consumption and caffeine-containing beverage consumption were negatively associated with urinary Na/K excretion. | Lee, Yeon-Kyung; Heo, Young-Ran; Hyun, Taisun; Lyu, Eun-Soon; Park, Haeryun; Ro, Hee-Kyong; Choi, Mi-Kyeong | Kyungpook Natl Univ, Dept Food Sci & Nutr, Daegu, South Korea; Chonnam Natl Univ, Res Inst Human Ecol, Div Food & Nutr, Gwangju, South Korea; Chungbuk Natl Univ, Dept Food & Nutr, Cheongju, South Korea; Pukyong Natl Univ, Dept Food Sci & Nutr, Busan, South Korea; Myongji Univ, Dept Food & Nutr, Yongin, South Korea; Dongshin Univ, Dept Food & Nutr, Naju, South Korea; Kongju Natl Univ, Dept Food & Nutr, 54 Daehak Ro, Yesan 32439, South Korea | Lee, Yeon-Kyung/AAA-1916-2020 | mkchoi67@kongju.ac.kr; | TRACE ELEMENTS AND ELECTROLYTES | TRACE ELEM ELECTROLY | 0946-2104 | 39 | 1 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;ENDOCRINOLOGY & METABOLISM | 2021 | 0.492 | 97.6 | 0 | beverages sodium potassium urinary excretion daily intake young adults | SUGAR-SWEETENED BEVERAGES; SALT INTAKE; CONSUMPTION; RISK; SODIUM; ADOLESCENTS; CAFFEINE; CHILDREN; NUTRIENT; OBESITY | English | 2021 | 2021 | 10.5414/tex01682 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Why do Sovereign Wealth Funds Invest in Asia? | Purpose - This paper aims to examine the determinants of SWFs' investment in Asian countries and to identify consistent investment patterns of SWFs in specific target firms from Asia, particularly China and South Korea. Design/methodology - This study extends the Tobin's Q model to examine the relationship between SWF investments in target firms and their returns with other firm-level control variables. We collect consistent data on SWF investments and the matched firm-level data on target firms, which of observation is 1,512 firms (333 in South Korea and 1,179 in China) targeted by 20 SWF sources during 1997-2017. The panel random effect model is used to estimate the extended Tobin's Q model. The robustness of the estimations is tested by the simultaneous equation models and the panel GEE model. Findings - The evidence shows that sovereign wealth funds are more inclined to invest in the financial sector with a monopoly position and in large firms with higher growth opportunity and superior cash asset ratios in China. In contrast to their investments in China, sovereign wealth funds in South Korea prefer to invest in strategic sectors, such as energy and information technology, and in large firms with high performance and low leverage. Sovereign wealth funds' investments tend to significantly improve the target firm's performance measured by sales growth and returns in both Korea and China. Originality/value - The existing literature focuses on examining the determination of SWFs investment in the developed countries, such as Europe and the United States. Our paper contributes to the literature in three ways; first, we analyzes case studies of SWF investments in Asian markets, which are less developed and riskier. Second, we examine whether the determination of SWF investment in Asian target firms depends on the different time periods, on types of sources of SWFs, and on acquiring countries. Third, our research uses vast sample data on target firms in longer time periods (1997-2017) than other previous studies on the SWFs for Asian markets. | Zhang, Hongxia; Kim, Heeho | Shandong Normal Univ, Sch Econ, Jinan, Peoples R China; Kyungpook Natl Univ, Sch Econ & Trade, Daegu, South Korea | Kim, Heeho/AAO-8809-2021 | 57199714616; 36727893700 | kimhh@knu.ac.kr; | JOURNAL OF KOREA TRADE | J KOREA TRADE | 1229-828X | 25 | 1 | SSCI | ECONOMICS | 2021 | 0.273 | 98.0 | 0 | 2025-07-30 | 0 | 0 | Asian Target Firms; Financial Sector; Sovereign Wealth Funds; Strategic Sector | INSTITUTIONAL INVESTORS; SHAREHOLDER ACTIVISM; DETERMINANTS; PREFERENCES; BIAS | Asian Target Firms; Financial Sector; Sovereign Wealth Funds; Strategic Sector | English | 2021 | 2021-02 | 10.35611/jkt.2021.25.1.65 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Soy Protein Remnants Digested by Gastro-duodenal Proteases can Alter Microbial Interactions and Intestinal Cholesterol Absorption | Background: Although the food quality of soy protein is known to be as good as that of animal proteins, some soybean proteins are not susceptible to digestion and remain undigested in the intestine. We hypothesized that digestion-resistant soy proteins might interact with the intestinal membrane, microbes, and metabolites, and change the intestinal physiology or the profile of the gut microbiome. Objective: To identify the Protease-Resistant Soy Proteins (PRSPs) and their interaction with intestinal membrane proteins by MS, and to assess the functions of PRSPs in the small intestine. Methods: Soy proteins were sequentially digested with pepsin and pancreatin, and the PRSPs were identified by SDS-PAGE and MS. Intestinal cell membrane proteins interacting with PRSPs were isolated by affinity purification and photo-affinity crosslinking, and identified using MS/MS. Inhibition of cholesterol absorption to lipoprotein-depleted intestinal cells, CaCo-2, and hepatic cells, HepG2, was measured in the presence and absence of PRSPs. FITC-conjugated Gram-positive, Lactobacillus plantarum, and Gram-negative bacteria, Escherichia coli, were incubated with CaCo-2 cells in the presence of PRSPs to investigate the regulation of bacterial cell binding to intestinal epithelial cells by PRSPs. Results: MS/MS of PRSPs identified glycinin, beta-conglycinin, trypsin inhibitors, lipoxygenase, and sucrose-binding protein. MS analysis also identified the intestinal membrane proteins bound to PR- Mark SPs. The functions of the identified interacting proteins included ion transportation, carbohydrate-binding, cytoskeleton formation, hydrolysis, cell-cell junction formation, and cholesterol/steroid-binding. In particular, apolipoprotein E, aminopeptidase N, and Niemann-Pick C1-like protein 1 are known to be involved in cholesterol absorption in the small intestine. The inhibition of cholesterol absorption by CaCo-2 and HepG2 cells by PRSPs confirmed the MS results. Binding of L. plantarum and E. coli to CaCo-2 cells was efficiently inhibited by PRSPs. Conclusion: PRSPs can interact with intestinal membrane proteins, and regulate cholesterol absorption by intestinal epithelial cell and interactions of the gut microbiome. Soy protein in the intestine acts as a nutrient, and triggers changes in intestinal functions by interacting with intestinal cells, microorganisms, and nutrients. These findings will provide valuable new functional information about the effects of soy proteins on human health. | Lee, Juyoung; Yum, Yujin; Kim, Sunghee; Katimbwa, Dorsilla Anono; Lim, Jinkyu | Kyungpook Natl Univ, Major Food Biomat, Daegu, South Korea | 57001671600; 57222068973; 57203773688; 57221787136; 7403454071 | jkylim@knu.ac.kr; | CURRENT PROTEOMICS | CURR PROTEOMICS | 1570-1646 | 1875-6247 | 18 | 2 | SCIE | BIOCHEMICAL RESEARCH METHODS;BIOCHEMISTRY & MOLECULAR BIOLOGY | 2021 | 0.642 | 98.2 | 0.14 | 2025-07-30 | 1 | 2 | Soy proteins; pepsin- and pancreatin-resistant proteins; gut epithelial cells; interacting proteins; bacterial cell binding; cholesterol transport | GENETICALLY-OBESE MICE; AMINOPEPTIDASE-N CD13; SPATIAL-ORGANIZATION; MASS; DIGESTIBILITY; HYDROLYSATE; INHIBITION; EXTRACTION; STRATEGIES; ISOLATE | Bacterial cell bind-ing; Cholesterol transport; Gut epithelial cells; Interacting proteins; Pepsin-and pancreatin-resistant proteins; Soy proteins | 2 membrane associated progesterone receptor component; albumin; apolipoprotein E; beta amylase; beta conglycinin alpha; beta conglycinin beta; cadherin receptor 3; calnexin; carbohydrate binding protein; cell membrane protein; chloride channel calcium activated 3; cholesterol; desmin; desmoplakin isoform 1; epithelial cell adhesion molecule; ezrin; fluorescein isothiocyanate; galaptin; glycinin; glycinin G1; glycinin G2; glycinin G3; glycinin G4; intersectin 1; junction plakoglobin; Kunitz type trypsin inhibitor; lectin; linoleate 9 lipoxygenase 1; linoleate 9 lipoxygenase 2; linoleate 9 lipoxygenase 3; lipoxygenase; malectin; meprin A subunit alpha; meprin A subunit beta; microsomal aminopeptidase; moesin; murinoglobulin; nesprin 2; Niemann Pick C1 like protein 1; pancreatin; pepsin A; Pgm3 protein; proteinase; proteoglycan 2; regenerating islet derived protein 4; seed maturation protein; sodium potassium transporting ATPase subunit alpha 1; soybean protein; sucrase isomaltase; sucrose binding protein; trypsin inhibitor; trypsin inhibitor A; trypsin inhibitor B; unclassified drug; affinity chromatography; Article; bacterial cell; Caco-2 cell line; cell junction; controlled study; cytoskeleton; Escherichia coli; Hep-G2 cell line; human; human cell; intestine absorption; intestine epithelium cell; ion transport; Lactobacillus plantarum; liquid chromatography-mass spectrometry; liver cell; microbial interaction; nonhuman; polyacrylamide gel electrophoresis; priority journal; protein cross linking; protein degradation; protein function; protein hydrolysis; protein isolation; protein protein interaction; protein purification; small intestine; steroid binding | English | 2021 | 2021 | 10.2174/1570164617666200305113924 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Determining the effect of ellagic acid on the proliferation and migration of pancreatic cancer cell lines | Background: Ellagic acid is a natural dietary compound found in several berries and fruits. It inhibits fibrosis, inflammation and carcinogenesis. We tried to find out what role ellagic acid plays in pancreatic cancer to see if it can be used as an adjuvant for chemotherapy. Methods: Three pancreatic cancer cell lines, PANC-1, AsPC-1, and MTA PaCA-2, were used. Cell growth was measured by MAT assay. Activities of caspase-3 and caspase-8, and caspase-9 were evaluated to determine the apoptosis pathway. Epithelial to mesenchymal transition was identified through mRNA expression of associated genes, which were transforming growth factor-beta, matrix metalloproteinase-2 and matrix metalloproteinase-9. Quantitative real time PCR was used to verify mRNA expression. To determine the effect on migration, transwell system was used. Results: Ellagic acid inhibits pancreatic cancer cell growth by stimulating apoptosis. Apoptosis induced by ellagic acid in pancreatic cancer cells, is mediated by the activation of caspase-3 and caspase-9, and not caspase-8. Ellagic acid also suppresses migration via the inhibition of epithelial mesenchymal transition (EMT) in pancreatic cancer cells. Ellagic acid decreased the expression levels of transforming growth factorbeta, matrix metalloproteinase-2 and matrix metalloproteinase-9, while it increased that of E-cadherin. Conclusions: These findings suggest that ellagic acid is useful in pancreatic cancer treatment. | Kim, Ji Yoon; Choi, Yun Ju; Kim, Ha-Jeong | Kyungpook Natl Univ, Sch Med, Dept Pediat, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Physiol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biomed Sci, BK21 Plus KNU Biomed Convergence Program, Daegu, South Korea | 57205408095; 57221969212; 57191717512 | kimhajeong@knu.ac.kr; | TRANSLATIONAL CANCER RESEARCH | TRANSL CANCER RES | 2218-676X | 2219-6803 | 10 | 1 | SCIE | ONCOLOGY | 2021 | 0.496 | 98.6 | 1.42 | 2025-07-30 | 23 | 24 | Ellagic acid; pancreatic cancer; proliferation; apoptosis; migration | Apoptosis; Ellagic acid; Migration; Pancreatic cancer; Proliferation | caspase 3; caspase 8; caspase 9; complementary DNA; ellagic acid; gelatinase A; gelatinase B; messenger RNA; transforming growth factor beta; uvomorulin; apoptosis; Article; AsPC-1 cell line; cancer growth; cancer inhibition; cell growth; cell migration; cell proliferation; controlled study; enzyme activation; enzyme activity; epithelial mesenchymal transition; gene expression; gene expression level; MIA PaCa-2 cell line; MTT assay; PANC-1 cell line; pancreas cancer; real time polymerase chain reaction; tumor gene | English | 2021 | 2021-01 | 10.21037/tcr-20-2446 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Periostin is a novel histological biomarker for the diagnosis of chondroid tumor | Background: The chondroid tumor is generally classified into three types, enchondroma, low-grade chondrosarcoma, and high-grade chondrosarcoma. A histological evaluation of a biopsy sample is the best predictor of the clinical course in most patients with carcinomas or sarcomas. Sometimes serological or molecular markers are used as prediction markers, but there has been no reliable marker for chondroid tumor diagnosis. Clinical and radiological, but not histological features, are still used in the diagnosis and staging of chondroid tumors. During a histopathological diagnosis, it has been difficult to distinguish between benign enchondroma and low-grade chondrosarcoma. To allow for more accurate treatments, new histological biomarkers for the differential diagnosis are needed. Methods: Twenty-eight cases of enchondromas and thirty-three cases of low-grade chondrosarcoma were selected. 'Thirteen cases of non-tumorous cartilage were used for the control group, who underwent artificial joint surgery for degenerative arthritis. Surgically removed tissue specimens were formalin-fixed paraffin-embedded and hematoxylin and eosin (H& E) and immunohistochemistry (HIC) stains were performed. Results: Periostin was expressed in chondroid tumors but not in the normal cartilage. Periostin was observed via immunostaining in the cytoplasm but not in the extracellular matrix of enchondroma tissue, and was observed in the cytoplasm and extracellular matrix of low-grade chondrosarcoma. The sensitivity and specificity of these stains were 93.9% and 96.4%, respectively. Conclusions: Based on these results, we suggest that periostin could be used as a novel prognostic marker to distinguish between enchondroma and low-grade chondrosarcoma. | Kim, Dough; Jeong, Ji Yun; Han, Man-Hoon; Chae, Jongmin; Park, Ilhyung; Yoon, Jongphil; Kyung, Heesoo; Kim, Ha-Jeong; Jeong, Wonju | Kyungpook Natl Univ, Sch Med, Dept Physiol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biomed Sci, BK21 Plus KNU Biomed Convergence Program, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pathol, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Pathol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Orthoped Surg, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Orthoped Surg, Daegu, South Korea | 57204810451; 57205472984; 57194067936; 7102478026; 35076285100; 36098548400; 7004292406; 57191717512; 36657279200 | kimhajeong@knu.ac.kr;wjjeong@knu.ac.kr; | TRANSLATIONAL CANCER RESEARCH | TRANSL CANCER RES | 2218-676X | 2219-6803 | 10 | 1 | SCIE | ONCOLOGY | 2021 | 0.496 | 98.6 | 0.25 | 2025-07-30 | 4 | 3 | Periostin; cartilage; enchondroma; low-grade chondrosarcoma; differential diagnosis marker | GRADE; CHONDROSARCOMA; IDENTIFICATION; CRYOSURGERY; EXPRESSION; PROTEIN | Cartilage; Differential diagnosis marker; Enchondroma; Low-grade chondrosarcoma; Periostin | eosin; formaldehyde; hematoxylin; paraffin; transcription factor RUNX2; adult; aged; Article; cancer tissue; chondrosarcoma; clinical article; controlled study; cytoplasm; diagnostic test accuracy study; enchondroma; extracellular matrix; female; human; human tissue; immunohistochemistry; male; osteoarthritis; sensitivity and specificity; tumor diagnosis | English | 2021 | 2021-01 | 10.21037/tcr-20-2499 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
