| ○ | ○ | Article | Operational Performance Evaluation of Korean Ship Parts Manufacturing Industry Using Dynamic Network SBM Model | The purpose of this study is to analyze the efficiency and productivity of the Korean ship parts manufacturing industry. To this end, the manufacturing process was divided into two stages (operating activities, financial activities), and the Dynamic Network SBM model and Malmquist Productivity Index were used. We collected analysis data from KIS-VALUE, and analyzed 40 companies from 2014 to 2020. As a result of the analysis, from 2014 to 2017, the average operating efficiency was 0.7825, the average financial efficiency was 0.5208, and the average total efficiency was 0.4537. It was found that improving efficiency requires improving both activities simultaneously, rather than focusing on a specific activity. Operating activities DMI was 1.0025, financial activities DMI was 0.9236, and OMI was 0.9464. In order to improve OMI, it is necessary to improve the financial activities DMI, which is the cause of the decrease in productivity. In order to improve financial activities DMI, government policy or technology change to improve DFS was found to be necessary. Finally, the effect of environmental factors on efficiency was analyzed by tobit regression. It was found that Firm Size had a negative (-) effect on efficiency, and Firm Age had a positive (+) effect on efficiency. The analysis results of this study will help to understand the relationship between input and output, which has been treated as a black box in the manufacturing industry, in two stages; and this will serve as a guideline for those working in Korea's ship parts manufacturing industry to establish policies. | Park, Sungmin; Kim, Pansoo | Kyungpook Natl Univ, Sch Business Adm, Daegu 41566, South Korea | 57354478200; 56290176300 | bomsungmin@gmail.com;pskim@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 23 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.42 | 2025-07-30 | 4 | 7 | ship parts manufacturing industry; efficiency; data envelopment analysis; productivity; malmquist productivity index; operational performance | DEA MODEL; FINANCIAL INDICATORS; EFFICIENCY; IMPACT | Data envelopment analysis; Efficiency; Malmquist productivity index; Operational performance; Productivity; Ship parts manufacturing industry | Korea; economic activity; environmental factor; government; guideline; manufacturing; numerical model; performance assessment; productivity | English | 2021 | 2021-12 | 10.3390/su132313127 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Optimal Installation Location of Escape Route Signs at T-Type Intersections | This study analyzed the decision-making times (DMTs) of participants at T-type indoor intersections according to the horizontal/vertical installation locations and the arrow directions of escape route signs. A total of 120 university students participated in the study. We analyzed the DMTs and following rates (FRs) required for the participants to observe the visual stimuli of the signs installed in front of the T-type indoor intersections and then properly select a path according to the arrow direction of the signs. The results are as follows: (1) the participants exhibited shorter DMTs for the right arrow direction of the signs, (2) the Simon effect occurred when the horizontal installation location of the signs was more than 60 cm away from the center of the T-type indoor intersection on both sides, (3) the DMTs of participants increased when the vertical installation location of the signs was low. Finally, we proposed an optimal installation location of the signs to support the shortest DMTs at T-type indoor intersections. It is expected that the results of this study will provide a database of DMTs, based on the locations of the signs during emergency evacuations, and will be utilized to improve the installation guidelines and regulations of signs. | Bae, Young-Hoon; Son, Jong-Yeong; Oh, Ryun-Seok; Lee, Hye-Kyoung; Lee, Yoon-Ha; Hong, Won-Hwa; Choi, Jun-Ho | Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Daegu 41566, South Korea; Natl Disaster Management Res Inst, Disaster Informat Res Div, Ulsan 44538, South Korea; Pukyong Natl Univ, Res Inst Intelligent Fire Safety Technol & Human, Busan 48513, South Korea; Changshin Univ, Dept Fire & Disaster Prevent Engn, Chang Won 51352, South Korea; Pukyong Natl Univ, Div Architectural & Fire Protect Engn, Busan 48513, South Korea | 57217673662; 57216338373; 57216343532; 57209320452; 57218699556; 7401527968; 55532956500 | byh0105@gmail.com;ssonjy2239@gmail.com;trot36@hanmail.net;dldbsgk123@naver.com;hongwonhwa@gmail.com;jchoi@pknu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 14 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.35 | 2025-07-30 | 4 | 5 | escape route signs; decision-making times; virtual stimuli; T-type intersection; optimal installation location | EXIT SIGNS; EMERGENCY; CHOICE | Decision-making times; Escape route signs; Optimal installation location; T-type intersection; Virtual stimuli | decision making; installation; location decision; university sector | English | 2021 | 2021-07 | 10.3390/su13147903 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Perceived Exposure and Acceptance Model of Appearance-Related Health Campaigns: Roles of Parents' Healthy-Appearance Talk, Self-Objectification, and Interpersonal Conversations | Excessive focus on appearance or lookism requires social attention as it can have negative consequences on individuals' psychological and mental states related to health and sustainable social practice. As part of a healthy and sustainable social practice, this study tests the mechanism of enhancing appearance-related health campaign's effectiveness through the O1-S-O2-R framework. Participants were 220 Korean college students with being 141 male and 78 female and they completed an on-line survey. The result of SEM analyses confirmed the O1-S-O2-R model. As the result of hypotheses testing, health campaign contents suggesting anti-lookism and diverse beauty standards have attracted the attention of people whose parents conversed using relatively less healthy-appearance talk when growing up and who had higher self-objectification scores with body surveillance and body shame. Interpersonal conversations and thoughts on the media content played a mediating role in the model, while health campaigns had a higher persuasive effect on campaign evaluation and the behavior intention of spreading the campaign's content. Implications of the findings were discussed regarding health campaign designers and individuals, including parents, in education settings. | Lee, Eunsoon; Lee, Gyu-il | Dong A Univ, Dept Media & Commun, Busan 49236, South Korea; Kyungpook Natl Univ, Dept Phys Educ, Daegu 41566, South Korea | 59645597600; 58118889300 | eunslee11@gmail.com;mauri94@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 6 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.14 | 2025-07-30 | 2 | 3 | appearance-related health campaigns; parents’ healthy-appearance talk; self-objectification; interpersonal conversations | BODY-IMAGE; ADOLESCENT GIRLS; INFORMATION-SEEKING; FAT TALKING; MEDIA USE; COMMUNICATION; WOMEN; INTERNALIZATION; DISSATISFACTION; BEHAVIORS | Appearance-related health campaigns; Interpersonal conversations; Parents’ healthy-appearance talk; Self-objectification | Korea; education; health impact; mental health; numerical model; perception; pollution exposure; psychology; public health; student; sustainability; sustainable development | English | 2021 | 2021-03 | 10.3390/su13063445 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Pollutant-Removing Biofilter Strains Associated with High Ammonia and Hydrogen Sulfide Removal Rate in a Livestock Wastewater Treatment Facility | This study analyzed the microbial community metagenomically to determine the cause of the functionality of a livestock wastewater treatment facility that can effectively remove pollutants, such as ammonia and hydrogen sulfide. Illumina MiSeq sequencing was used in analyzing the composition and structure of the microbial community, and the 16S rRNA gene was used. Through Illumina MiSeq sequencing, information such as diversity indicators as well as the composition and structure of microbial communities present in the livestock wastewater treatment facility were obtained, and differences between microbial communities present in the investigated samples were compared. The number of reads, operational taxonomic units, and species richness were lower in influent sample (NLF), where the wastewater enters, than in effluent sample (NL), in which treated wastewater is found. This difference was greater in June 2019 than in January 2020, and the removal rates of ammonia (86.93%) and hydrogen sulfide (99.72%) were also higher in June 2019. In both areas, the community composition was similar in January 2020, whereas the influent sample (NLF) and effluent sample (NL) areas in June 2019 were dominated by Proteobacteria (76.23%) and Firmicutes (67.13%), respectively. Oleiphilaceae (40.89%) and Thioalkalibacteraceae (12.91%), which are related to ammonia and hydrogen sulfide removal, respectively, were identified in influent sample (NLF) in June 2019. They were more abundant in June 2019 than in January 2020. Therefore, the functionality of the livestock wastewater treatment facility was affected by characteristics, including the composition of the microbial community. Compared to Illumina MiSeq sequencing, fewer species were isolated and identified in both areas using culture-based methods, suggesting Illumina MiSeq sequencing as a powerful tool to determine the relevance of microbial communities for pollutant removal. | Kim, Dong-Hyun; Yun, Hyun-Sik; Kim, Young-Saeng; Kim, Jong-Guk | Kyungpook Natl Univ, Sch Appl Biosci, Daegu 37224, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Biol, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Ulleung Do & Dok Do, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Life Sci, BK21 Four KNU Creat BioRes Grp, Daegu 41566, South Korea | ; Kim, Dong Hyun/LDT-2672-2024 | 59444469900; 57215320824; 35798433500; 35277198800 | kgwkk1@naver.com;yoon92623@naver.com;kyslhh1228@hanmail.net;kimjg@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 13 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.28 | 2025-07-30 | 3 | 4 | ammonia removal; hydrogen sulfide removal; Illumina MiSeq; microbial community; wastewater treatment facility | CD-HIT; BACTERIA; CHROMATOGRAPHY; BIOREACTOR; MEMBRANE; PROTEIN; NITRATE; SYSTEM; SLUDGE; NOV. | Ammonia removal; Hydrogen sulfide removal; Illumina MiSeq; Microbial community; Wastewater treatment facility | Oleiphilaceae; Proteobacteria; ammonia; community composition; hydrogen sulfide; microbial community; pollutant removal; RNA; wastewater; wastewater treatment; wastewater treatment plant | English | 2021 | 2021-07 | 10.3390/su13137358 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Status of Environmental Life Cycle Assessment (LCA): A Case Study of South Korea | The Life Cycle Assessment (LCA) as an environmental-impact assessment tool has received increasing attention over the years. Unlike the water footprint (WF) and carbon footprint (CF) assessments, whose focus is only on a single environmental aspect, the LCA systematically analyzes the different impacts along the entire life cycle, making possible the identification of potential environmental tradeoffs. In Korea, LCA has drawn much attention from both industry and academia since the mid-1990s. However, the level of Korean-related LCA studies with respect to different sectors in the last 20 years has not been analyzed. This study, therefore, sought to assess the status of environmental Life Cycle Assessment (LCA) studies in South Korea. Specifically, the study focused on a bibliometric review of LCAs conducted in South Korea in the last 20 years and identified potential research gaps. Online searches of English-written articles published between 2000 and 2019 were conducted on Google, Google Scholar, Scopus, and Web of Science databases, using eligible keywords. At the end of the search, about 91 LCA-related studies were discovered for South Korea within the study period. The majority of these studies focused on the construction (47%) and energy (30%) sectors, with fewer environmental studies on manufacturing (11%), transportation (9%), agriculture (2%), and information and communication (1%) industries. Based on publication trends, results show that LCA studies in South Korea have been on the rise in the past 20 years, even though the number of publications has not followed a constant pace. In comparison with the economic sectors of the country, reports show an inadequacy in the coverage of major industries of growing economic relevance, such as tourism, health, and agriculture, suggesting a need to increase and improve LCA-related studies in these sectors. | Odey, Golden; Adelodun, Bashir; Kim, Sang-Hyun; Choi, Kyung-Sook | Kyungpook Natl Univ, Dept Agr Civil Engn, Daegu 41566, South Korea; Univ Ilorin, Dept Agr & Biosyst Engn, Ilorin 240003, Nigeria; Kyungpook Natl Univ, Inst Agr Sci & Technol, Daegu 41566, South Korea | ; Adelodun, Bashir/O-2941-2018; Odey, Golden/MVV-6310-2025 | 57211444984; 57193774482; 57211805802; 54392662900 | goldenodey@knu.ac.kr;adelodun.b@unilorin.edu.ng;sangddong2@gmail.com;ks.choi@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 11 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 1.27 | 2025-07-30 | 15 | 21 | Life Cycle Assessment (LCA); environmental impact assessment; sustainability reporting; Korea | GREENHOUSE-GAS EMISSIONS; CARBON-DIOXIDE EMISSIONS; FOOD WASTE MANAGEMENT; APARTMENT BUILDINGS; IMPACT-ASSESSMENT; ASSESSMENT MODEL; CO2 EMISSIONS; STORAGE INFRASTRUCTURE; CERTIFICATION SYSTEM; ASSESSMENT PROGRAM | Environmental impact assessment; Korea; Life Cycle Assessment (LCA); Sustainability reporting | South Korea; Scopus; carbon footprint; information and communication technology; life cycle analysis; water footprint | English | 2021 | 2021-06 | 10.3390/su13116234 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | The Effect of ESG Activities on Financial Performance during the COVID-19 Pandemic-Evidence from Korea | This study examines the effect of a firm's environmental, social, and governance (ESG) activities on its financial performance during the acute uncertainty caused by the COVID-19 pandemic. Due to the COVID-19 pandemic, most Korean firms suffered unexpected difficulties in their business activities in early 2020, and their financial performance deteriorated significantly. The purpose of this study is to empirically analyze whether a firm's ESG activities affect its financial performance during a business crisis. The results show that, in the first quarter of 2020, when the impact of the COVID-19 pandemic occurred, firms' earnings dropped significantly; however, we found that the higher the performance of ESG activities, the smaller the decline in earnings. The results imply that, in an environment of uncertainty, the performance of a firm's ESG activities is reflected in its financial outcomes. This result implies that trust and bond between firms and stakeholders, as formed through investments in social capital, are rewarded when the overall level of sustainability in markets is negatively impacted. In addition, our results suggest that the performance of nonfinancial activities is useful information for stakeholders' decision making in relation to market uncertainty. | Hwang, Juhee; Kim, Hyuna; Jung, Dongjin | Kyungpook Natl Univ, Sch Business Adm, 80 Daehak Ro, Daegu 41566, South Korea | 57209750725; 57298173700; 57297356100 | jhhwang10@knu.ac.kr;hyunakim@knu.ac.kr;jdj1875@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 20 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 3.39 | 2025-07-30 | 50 | 61 | COVID-19; ESG; financial performance; social capital | CORPORATE SOCIAL-RESPONSIBILITY; MANAGEMENT; PHILANTHROPY | COVID-19; ESG; Financial performance; Social capital | Korea; COVID-19; decision making; detection method; firm size; market conditions; spatiotemporal analysis; stakeholder; sustainability | English | 2021 | 2021-10 | 10.3390/su132011362 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The Impact of the COVID-19 on Economic Sustainability-A Case Study of Fluctuation in Stock Prices for China and South Korea | The coronavirus disease (COVID-19) pandemic has had a global impact on lives, livelihoods, and economies. This study investigates whether a contagious infectious disease can affect the prices of the Chinese and Korean stock markets. Specifically, we aim to discover discrepancies in the impact of COVID-19 on the stock prices of China and South Korea through panel data. To test these discrepancies, we first regressed the stock indices on confirmed cases and deaths. We then validated the stability of coefficients over the past days. The empirical results show that (1) responses of stock indices are stable and impulsive and (2) response patterns toward COVID-19 events considerably vary across nations, especially in the counties such as China and South Korea. | Jiang, Jialei; Park, Eun-Mi; Park, Seong-Taek | Xuzhou Univ Technol, Sch Management, Xuzhou 221018, Jiangsu, Peoples R China; Kyungpook Natl Univ, Sch Business Adm, Daegu 41566, South Korea; Chungbuk Natl Univ, Dept Management Informat Syst, Cheongju 28644, South Korea | 57224894861; 56352305900; 56352364700 | jiangjialei@xzitedu.cn;issack25@knu.ac.kr;solpherd@cbnu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 12 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.57 | 2025-07-30 | 8 | 8 | economic sustainability; COVID-19; stock price; big data analytics; MA model | MARKET; CORONAVIRUS; OUTBREAK | Big data analytics; COVID-19; Economic sustainability; MA model; Stock price | China; South Korea; Coronavirus; COVID-19; economic analysis; infectious disease; livelihood; panel data; price dynamics; stock market; sustainability | English | 2021 | 2021-06 | 10.3390/su13126642 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | U-Net-Based Foreign Object Detection Method Using Effective Image Acquisition System: A Case of Almond and Green Onion Flake Food Process | Supervised deep learning-based foreign object detection algorithms are tedious, costly, and time-consuming because they usually require a large number of training datasets and annotations. These disadvantages make them frequently unsuitable for food quality evaluation and food manufacturing processes. However, the deep learning-based foreign object detection algorithm is an effective method to overcome the disadvantages of conventional foreign object detection methods mainly used in food inspection. For example, color sorter machines cannot detect foreign objects with a color similar to food, and the performance is easily degraded by changes in illuminance. Therefore, to detect foreign objects, we use a deep learning-based foreign object detection algorithm (model). In this paper, we present a synthetic method to efficiently acquire a training dataset of deep learning that can be used for food quality evaluation and food manufacturing processes. Moreover, we perform data augmentation using color jitter on a synthetic dataset and show that this approach significantly improves the illumination invariance features of the model trained on synthetic datasets. The F1-score of the model that trained the synthetic dataset of almonds at 360 lux illumination intensity achieved a performance of 0.82, similar to the F1-score of the model that trained the real dataset. Moreover, the F1-score of the model trained with the real dataset combined with the synthetic dataset achieved better performance than the model trained with the real dataset in the change of illumination. In addition, compared with the traditional method of using color sorter machines to detect foreign objects, the model trained on the synthetic dataset has obvious advantages in accuracy and efficiency. These results indicate that the synthetic dataset not only competes with the real dataset, but they also complement each other. | Son, Guk-Jin; Kwak, Dong-Hoon; Park, Mi-Kyung; Kim, Young-Duk; Jung, Hee-Chul | DGIST, ICT Res Inst, Daegu 42988, South Korea; Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea | ; Park, Mi-Kyung/J-9643-2017; Jung, Heechul/HTL-7199-2023 | 57191336333; 57222297059; 7404491155; 55955831300; 55652175200 | sudopop@dgist.ac.kr;gns9452@dgist.ac.kr;parkmik@knu.ac.kr;ydkim@dgist.ac.kr;heechul@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 24 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.85 | 2025-07-30 | 12 | 14 | computer vision; foreign object detection; deep learning; data augmentation | BODIES | Computer vision; Data augmentation; Deep learning; Foreign object detection | algorithm; detection method; food processing; food quality; image analysis; machine learning | English | 2021 | 2021-12 | 10.3390/su132413834 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Weighting the Attributes of Human-Related Activities for Fire Safety Measures in Historic Villages | Recently, numerous world heritage sites have burned down or suffered minor damage due to fires. As a result, the Korean government has developed active and passive fire measures in Korean historic villages. Nevertheless, fires have not been prevented, inciting the government to direct its attention toward community-based activities. This paper focuses on human-related fire safety measures and aims to identify the most efficient methods for preventing fires, as well as for minimizing damage caused by them in historic villages. It explores the preventive and response levels of residents and village organizations based on a survey of experts in the field and applies an analytic hierarchy process (AHP) to determine the weighting of the selected attributes. The study proposes that the preventive level is more important than the response level among village residents, and the response level should be prioritized over the preventive level in village organizations in order to prevent and reduce fire risk and damage in Korean historic villages. | Lee, Ji-Hee; Chun, Woo-Young; Choi, Jun-Ho | Kyungpook Natl Univ, Adv Technol Inst Construct Environm Energy, Daegu 41566, South Korea; Korea Conform Labs, Real Scale Fire Testing & Res Ctr, Samcheok 25913, South Korea; Pukyong Natl Univ, Div Architectural & Fire Protect Engn, Busan 48513, South Korea | 55857322700; 59822273700; 55532956500 | jihee@knu.ac.kr;cwy@kcl.re.kr;jchoi@pknu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 6 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.35 | 2025-07-30 | 5 | 5 | historic villages; fire safety; weighing of attributes; community-based activities; AHP analysis; residents | AHP analysis; Community-based activities; Fire safety; Historic villages; Residents; Weighing of attributes | Korea; analytical hierarchy process; community resource management; expert system; fire history; historical perspective; prioritization; risk assessment; safety; village; World Heritage Site | English | 2021 | 2021-03 | 10.3390/su13063236 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | A 9-Year Comparison of Dementia Prevalence in Korea: Results of NaSDEK 2008 and 2017 | Background: In many high-income Western countries, the prevalence of dementia had been reduced over the past decades. Objective: We investigated whether the prevalence of all-cause dementia, Alzheimer's disease, vascular dementia, and mild cognitive impairment (MCI) had changed in Korea from 2008 to 2017. Methods: Nationwide Survey on Dementia Epidemiology of Korea (NaSDEK) in 2008 and 2017 was conducted on representative elderly populations that were randomly sampled across South Korea. Both surveys employed a two-stage design (screening and diagnostic phases) and diagnosed dementia and MCI according to the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders and the consensus criteria from the International Working Group, respectively. The numbers of participants aged 65 years or older in the screening and diagnostic phases were 6,141 and 1,673 in the NaSDEK 2008 and 2,972 and 474 in the NaSDEK 2017, respectively. Results: The age- and sex-standardized prevalence of all-cause dementia and Alzheimer's disease showed nonsignificant decrease (12.3% to 9.8%, odds ratio [OR] = 0.89, 95% confidence interval [CI] = 0.54-1.48 for all-cause dementia; 7.6% to 6.8%, OR [95% CI] = 0.91 [0.58-1.42] for Alzheimer's disease). Vascular dementia decreased in the young-old population aged less than 75 years (2.7% to 0.001%, OR [95% CI] = 0.04 [0.01-0.15]) and in women (1.9% to 0.5%, OR [95% CI] = 0.27 [0.10-0.72]) while MCI remained stable (25.3% to 26.2%, OR [95% CI] = 1.08 [0.67-1.73]). Conclusion: We found that the prevalence of dementia in Korea showed a nonsignificant decrease between 2008 and 2017. | Suh, Seung Wan; Kim, You Joung; Kwak, Kyung Phil; Kim, Kiwon; Kim, Moon-Doo; Kim, Byung-Soo;

| ○ | ○ | Article | A Comparative Study on the Condensation Heat Transfer of R-513A as an Alternative to R-134a | This paper presents the two-phase condensation heat transfer and pressure drop characteristics of R-513A as an alternative refrigerant to R-134a in a 9.52-mm OD horizontal microfin copper tube. The test facility had a straight, horizontal test section with an active length of 2.0 m and was cooled by cold water circulated in a surrounding annular space. The annular-side heat transfer coefficients were obtained using the Wilson plot method. The average heat transfer coefficient and pressure drop data are presented at the condensation temperature of 35 degrees C in the range of 100-440 kg center dot m(-2)center dot s(-1) mass flux. The test data of R-513A are compared with those of R-134a, R-1234yf, and R-1234ze(E). The average condensation heat transfer coefficients of the R-513A and R-1234ze(E) refrigerants were similar to R-134a at the lower mass flux (100 similar to 150 kg center dot m(-2)center dot s(-1)), while they were up to 10% higher than R-134a as the mass flux increased. The pressure drop of R-513A was similar to R-1234yf and 10% lower than that of R-134a at the higher mass flux. The R-1234ze(E) pressure drops were 20 % higher compared to those of R-134a at the higher mass flux. | Karageorgis, Andreas; Hinopoulos, George; Kim, Man-Hoe | ElvalHalcor Co, Halcor Copper Tube Div, Oinofyta 32011, Viotia, Greece; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, IEDT, Daegu 41566, South Korea | 57224952830; 57201458638; 55686310000 | akarage@halcor.com;ghinopoulos@halcor.com;manhoe.kim@knu.ac.kr; | MACHINES | MACHINES | 2075-1702 | 9 | 6 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;ENGINEERING, MECHANICAL | 2021 | 2.899 | 44.2 | 0.7 | 2025-07-30 | 12 | 11 | condensation heat transfer; microfin tube; low-GWP refrigerant; R-513A; R-1234yf; R-1234ze(E) | HORIZONTAL SMOOTH; R134A; TUBE; REFRIGERANTS; R1234ZE(E); R410A; R22 | Condensation heat transfer; Low-GWP refrigerant; Microfin tube; R-1234yf; R-1234ze(E); R-513A | English | 2021 | 2021-06 | 10.3390/machines9060114 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Laser-induced graphene on a quartz crystal microbalance for humidity sensing | In this study, a simple method for synthesizing graphene layer directly on a quartz crystal microbalance (QCM) using a laser was developed. This laser-induced graphene (LIG) was used for sensing surface to simultaneously measure changes in the adsorbed mass, film stiffness, and electrical resistance during water adsorption. The developed LIG-QCM is convenient because its fabrication process is free of any tedious masking and vacuuming steps. A thin layer of polyimide (PI) film was spin-coated on one side of a quartz crystal microresonator, and interdigitated electrodes (IDE) were patterned on the PI surface using a laser engraver. The adsorption of water molecules on the sensing surface induced changes in mass, stiffness, and electrical conductivity, which were measured from the changes in resonance frequency, Q factor of the quartz crystal, and electrical resistance, respectively. The results indicated that the developed sensor could be a humidity sensing platform using LIG. © 2021 by the authors.

| ○ | ○ | Article | Potential Novel Genes for Late-Onset Alzheimer's Disease in East-Asian Descent Identified by APOE-Stratified Genome-Wide Association Study | The present study reports two novel genome-wide significant loci for late-onset Alzheimer's disease (LOAD) identified from APOE epsilon 4 non-carrier subjects of East Asian origin. A genome-wide association study of Alzheimer's disease was performed in 2,291 Korean seniors in the discovery phase, from the Gwangju Alzheimer's and Related Dementias (GARD) cohort study. The study was replicated in a Japanese cohort of 1,956 subjects that suggested two novel susceptible SNPs in two genes: PRIG1 and CACNA1A. This study demonstrates that the discovery of AD-associated variants is feasible in non-European ethnic groups using samples comprising fewer subjects from the more homogeneous genetic background. | Kang, Sarang; Gim, Jungsoo; Lee, Jiwoon; Gunasekaran, Tamil Iniyan; Choi, Kyu Yeong; Lee, Jang Jae; Seo, Eun Hyun; Ko, Pan-Woo; Chung, Ji Yeon; Choi, Seong-Min; Lee, Young Min; Jeong, Jee Hyang; Park, Kyung Won; Song, Min Kyung; Lee, Ho-Won; Kim, Ki Woong; Choi, Seong Hye; Lee, Dong Young; Kim, Sang Yun; Kim, Hoowon; Kim, Byeong C.; Ikeuchi, Takeshi; Lee, Kun Ho | Chosun Univ, Gwangju Alzheimers & Related Dementias Cohort Res, Gwangju, South Korea; Chosun Univ, Dept Integrat Biol Sci, Gwangju, South Korea; Neurozen Inc, Seoul, South Korea; Chosun Univ, Dept Biomed Sci, Gwangju 61452, South Korea; Chosun Univ, Dept Premed Sci, Coll Med, Gwangju, South Korea; Kyungpook Natl Univ, Dept Neurol, Sch Med, Daegu, South Korea; Chosun Univ Hosp, Dept Neurol, Gwangju, South Korea; Chonnam Natl Univ, Dept Neurol, Med Sch, Gwangju, South Korea; Pusan Natl Univ, Dept Psychiat, Sch Med, Busan, South Korea; Ewha Womans Univ, Sch Med, Dept Neurol, Mokdong Hosp, Seoul, South Korea; Dong A Univ, Dept Neurol, Coll Med, Busan, South Korea; Chonnam Natl Univ, Gwangju Geriatr Hosp 2, Gwangju, South Korea; Seoul Natl Univ, Dept Neuropsychiat, Bundang Hosp, Seongnam, South Korea; Inha Univ, Dept Neurol, Sch Med, Incheon, South Korea; Seoul Natl Univ Hosp, Dept Neuropsychiat, Seoul, South Korea; Seoul Natl Univ, Dept Neurol, Bundang Hosp, Seongnam, South Korea; Niigata Univ, Brain Res Inst, Dept Mol Genet, Niigata, Japan; Korea Brain Res Inst, Daegu, South Korea | Lee, Dong/J-5575-2012; Kim, Sang/J-5400-2012; Kim, Ki Woong/D-5801-2012; GUNASEKARAN, TAMIL INIYAN/LDF-8589-2024; lee, nan/HZM-0321-2023; Gim, Jungsoo/MBH-5198-2025 | 57221600616; 55624691500; 57227048600; 57222641926; 57193767645; 57201463442; 8412312400; 55543341200; 57054568100; 7408121966; 57203798770; 7402045750; 55722191100; 57207960205; 35337240700; 57529629700; 15838894900; 8554284500; 7601593906; 7410123341; 7501566739; 35378192400; 7409693862 | jgim@chosun.ac.kr;leekho@chosun.ac.kr; | JOURNAL OF ALZHEIMERS DISEASE | J ALZHEIMERS DIS | 1387-2877 | 1875-8908 | 82 | 4 | SCIE | NEUROSCIENCES | 2021 | 4.16 | 44.2 | 1.93 | 2025-07-30 | 24 | 24 | Alzheimer's disease; APOE; genome-wide association study; late-onset Alzheimer's disease; stratified genome analysis | SLOWER COGNITIVE DECLINE; METAANALYSIS; EXPRESSION; REVEALS; CALCIUM; SORL1; RISK | Alzheimer's disease; APOE; genome-wide association study; late-onset Alzheimer's disease; stratified genome analysis | Aged; Alzheimer Disease; Apolipoproteins E; Asian Continental Ancestry Group; Calcium Channels; Cohort Studies; Female; Genome-Wide Association Study; Humans; Japan; Longitudinal Studies; Male; Membrane Glycoproteins; Polymorphism, Single Nucleotide; Republic of Korea; apolipoprotein E; apolipoprotein E; CACNA1A protein, human; calcium channel; LRIG1 protein, human; membrane protein; aged; Alzheimer disease; Article; cacna1a gene; cohort analysis; controlled study; dementia; East Asian; ethnic group; female; gene; gene locus; genetic background; genetic susceptibility; genome analysis; genome-wide association study; human; Japanese (people); Korean (people); lrig1 gene; major clinical study; male; single nucleotide polymorphism; Alzheimer disease; Asian continental ancestry group; genetics; Japan; longitudinal study; South Korea | English | 2021 | 2021 | 10.3233/jad-210145 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Remdesivir Versus Standard-of-Care for Severe Coronavirus Disease 2019 Infection: An Analysis of 28-Day Mortality | Background. Remdesivir is approved by the US Food and Drug Administration for the treatment of patients hospitalized with coronavirus disease 2019 (COVID-19) and has been shown to shorten time to recovery and improve clinical outcomes in randomized trials. Methods. This was the final day 28 comparative analysis of data from a phase 3, randomized, open-label study comparing 2 remdesivir regimens (5 vs 10 days, combined for this analysis [remdesivir cohort]) and a real-world retrospective longitudinal cohort study of patients receiving standard-of-care treatment (nonremdesivir cohort). Eligible patients, aged >= 18 years, had confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), oxygen saturation <= 94% on room air or required supplemental oxygen, with pulmonary infiltrates. Propensity score matching (up to 1:10 ratio) was used to ensure comparable populations. We assessed day 14 clinical recovery (determined using a 7-point ordinal scale) and day 28 all-cause mortality (coprimary endpoints). Results. A total of 368 (remdesivir) and 1399 (nonremdesivir) patients were included in the matched analysis. The day 14 clinical recovery rate was significantly higher among the remdesivir versus the nonremdesivir cohort (65.2% vs 57.1%; odds ratio [OR], 1.49; 95% confidence interval [CI], 1.16-1.90; P = 0.002). The day 28 mortality rate was significantly lower in the remdesivir cohort versus the nonremdesivir cohort (12.0% vs 16.2%; OR, 0.67; 95% CI, 0.47-.95; P = .03). Conclusions. Remdesivir was associated with significantly higher rates of day 14 clinical recovery, and lower day 28 mortality, compared with standard-of-care treatment in hospitalized patients with COVID-19. These data, taken together, support the use of remdesivir to improve clinical recovery and decrease mortality from SARS-CoV-2 infection. | Olender, Susan A.; Walunas, Theresa L.; Martinez, Esteban; Perez, Katherine K.; Castagna, Antonella; Wang, Su; Kurbegov, Dax; Goyal, Parag; Ripamonti, Diego; Balani, Bindu; De Rosa, Francesco G.; De Wit, Stephane; Kim, Shin-Woo; Diaz, George; Bruno, Raffaele; Mullane, Kathleen M.; Lye, David Chien; Gottlieb, Robert L.; Haubrich, Richard H.; Chokkalingam, Anand P.; Wu, George; Diaz-Cuervo, Helena; Brainard, Diana M.; Lee, I-Heng; Hu, Hao; Lin, Lanjia; Osinusi, Anu O.; Bernardino, Jose, I; Boffito, Marta | Columbia Univ, Dept Internal Med, Div Infect Dis, Irving Med Ctr, New York, NY USA; Northwestern Univ, Feinberg Sch Med, Chicago, IL 60611 USA; Hosp Clin IDIBAPS, Barcelona, Spain; Univ Barcelona, Barcelona, Spain; Houston Methodist, Dept Pharm, Houston, TX USA; Univ Vita Salute San Raffaele, IRCCS San Raffaele, Milan, Italy; St Barnabas Hosp, RWJBarnabas Hlth Med Grp, Livingston, NJ USA; Sarah Cannon Res Inst, Nashville, TN USA; Weill Cornell Med, New York, NY USA; ASST Papa Giovanni XXIII, Bergamo, Italy; Hackensack Univ, Med Ctr, Hackensack, NJ USA; Univ Turin, Dept Med Sci, Turin, Italy; City Hlth & Sci, Turin, Italy; Cardinal Massaia Hosp, Asti, Italy; Univ Libre Bruxelles, NEAT ID Fdn, CHU St Pierre, Brussels, Belgium; Kyungpook Natl Univ Hosp, Daegu, South Korea; Providence Reg Med Ctr Everett, Everett, WA USA; Univ Pavia, Fdn IRCCS S Matteo Hosp, Pavia, Italy; Univ Chicago, Chicago, IL 60637 USA; Tan Tock Seng Hosp, Natl Ctr Infect Dis, Singapore, Singapore; Yong Loo Lin Sch Med, Singapore, Singapore; Lee Kong Chian Sch Med, Singapore, Singapore; Baylor Univ, Med Ctr Dallas, Dallas, TX USA; Baylor Scott & White Res Inst, Dallas, TX USA; Gilead Sci Inc, 353 Lakeside Dr, Foster City, CA 94404 USA; Gilead Sci SL, Madrid, Spain; Gilead Sci Ltd, Hong Kong, Peoples R China; Hosp Paz Inst Hlth Res IdiPAZ Madrid, Madrid, Spain; Chelsea & Westminster Hosp NHS Fdn Trust, London, England | Bernardino, Jose/H-7898-2017; Bruno, Raffaele/AAB-9491-2022; DE ROSA, Francesco Giuseppe/AAC-7275-2022; Gottlieb, Robert/AAM-8310-2020; Lye, David/ABF-4402-2021; Haubrich, Richard/KCJ-8103-2024; Hu, Hao/HZJ-7589-2023; ripamonti, diego/R-4898-2016 | 41361623400; 6603015849; 57204848862; 55387665900; 57201980205; 57226755274; 6505582993; 55099092500; 57201399171; 57201319162; 57226482885; 57203665572; 8710731500; 57215534788; 7101907548; 57190564229; 14016391200; 7102840849; 57210200091; 6603383936; 57191504682; 36801107000; 35093695100; 57226754188; 57221765643; 56063955900; 28568005400; 12752835500; 7004703572 | Richard.Haubrich@gilead.com; | OPEN FORUM INFECTIOUS DISEASES | OPEN FORUM INFECT DI | 2328-8957 | 8 | 7 | SCIE | IMMUNOLOGY;INFECTIOUS DISEASES;MICROBIOLOGY | 2021 | 4.433 | 44.2 | 2.27 | 2025-07-30 | 29 | 31 | COVID-19; mortality; remdesivir; SARS-CoV-2 | COVID-19 | COVID-19; mortality; remdesivir; SARS-CoV-2 | alanine aminotransferase; aspartate aminotransferase; azithromycin; Human immunodeficiency virus proteinase inhibitor; hydroxychloroquine; remdesivir; ribavirin; adult; aged; ambient air; Article; assessment of humans; body mass; cohort analysis; comorbidity; comparative study; controlled study; coronavirus disease 2019; disease duration; disease severity; estimated glomerular filtration rate; female; health care quality; hospitalization; human; invasive ventilation; longitudinal study; lung infiltrate; major clinical study; male; mortality; mortality rate; Ordinal Scale; oxygen saturation; oxygen supply; oxygen therapy; phase 3 clinical trial; polymerase chain reaction; propensity score; prospective study; randomized controlled trial; retrospective study; Severe acute respiratory syndrome coronavirus 2 | English | 2021 | 2021-07 | 10.1093/ofid/ofab278 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Screening of II-IV-V2 Materials for Photovoltaic Applications Based on Density Functional Theory Calculations | The relative stability of polymorphs and their electronic structure was investigated for II-IV-V-2 materials by using first-principles density functional theory calculations. Our calculation results show that, for Zn-, Cd-, and Be-containing compounds, nitrides favor the 2H polymorph with AB stacking sequence; however, phosphides, arsenides, and antimonides are more stable in the 3C polymorph with the ABC stacking sequence. The electronic band gap of materials was calculated by using hybrid density functional theory methods, and then materials with an ideal band gap for photovoltaic applications were chosen. The experimental synthesis of the screened materials is reported, except for CdSiSb2, which was found to be unstable in our calculation. The absorption coefficient of the screened materials, especially ZnGeAs2, was high enough to make thin-film solar cells. The higher stacking fault energy in ZnGeAs2 than the others is consistent with the larger formation energy difference between the 2H and 3C polymorphs. | Jeong, Byeong-Hyeon; Jeong, Minwoo; Song, Youbin; Park, Kanghyeon; Park, Ji-Sang | Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea | Park, Ji-Sang/F-9944-2010 | 57219744897; 57226549831; 57226551521; 57221558202; 36671796300 | qudgus1431@knu.ac.kr;style4480@knu.ac.kr;songyoubin@knu.ac.kr;kang-hyeon@knmac.kr;jsparkphys@knu.ac.kr; | CRYSTALS | CRYSTALS | 2073-4352 | 11 | 8 | SCIE | CRYSTALLOGRAPHY;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2021 | 2.67 | 44.2 | 0.08 | 2025-07-30 | 0 | 2 | semiconductor; solar cell; density functional theory | GROWTH; PREDICTION; CDSIAS2; STATE | Density functional theory; Semiconductor; Solar cell | English | 2021 | 2021-08 | 10.3390/cryst11080883 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
