This study aims to investigate Korean fashion-related research trends and knowledge structures on digital transformation through information-based approaches. Accordingly, we first identified the current status of the relevant research in Korean academic literature by year and journal; subsequently, we derived key research topics through network analysis, and then analyzed major research trends and knowledge structures by time. From 2010 to 2020, we collected 159 studies published on Korean academic platforms, cleansed data through Python 3.7, and measured centrality and network implementation through NodeXL 1.0.1. The results are as follows: first, related research has been actively conducted since 2016, mainly concentrated in clothing and art areas. Second, the online platform, AR/VR, appeared as the most frequently mentioned topic, and consumer psychological analysis, marketing strategy suggestion, and case analysis were used as the main research methods. Through clustering, major research contents for each sub-major of clothing were derived. Third, major subject by period was considered, which has, over time, changed from consumer-centered research to strategy suggestion, and design development research of platforms or services. This study contributes to enhancing insight into the fashion field on digital transformation, and can be used as a basic research to design research on related topics.

Social media users are an important part of our lives as they spend a lot of time and actively use them. However, it is known that there are many users who feel the psychological stress of SNS stress or fall into addiction due to SNS use. SNS stress negatively affects not only the user's mind but also the body. This study investigates the associations between SNS stress and addiction. To test the hypotheses, the study performed structural equation modeling using Amos. We collected 210 data from SNS users. The empirical results showed that SNS overuse had a significant effect on SNS stress. Second, SNS stress had a significant relationship with SNS addiction. Third, it was found that SNS overuse did not directly affect SNS addiction. This study suggests that it is necessary to recognize the importance of the relationship between SNS addiction and SNS stress.

This study investigates ethical dilemmas of teacher-librarians in their professional practice. Within the framework of "Librarians' Statement of Ethics" by Korean Library Association, the study used the survey and semi-structured interview with teacher-librarians. 259 teacher-librarians responded the survey and 5 teacher-librarians participated the interview. The survey was analyzed using descriptive statistics to find how often teacher-librarians experience ethical dilemmas. The semi-structured interview was transcribed and analyzed to draw the individual cases of teacher-librarians' ethical dilemmas. The results indicate that teacher-librarians experience ethical dilemmas in relation to information access and intellectual freedom most often. It was difficult for teacher-librarians to relate their professional duties with their expertise and that they were not clear on how to avoid copyright issues and how to deal with the balance between users and copyright holders. This study had implications that individual dilemma cases are so context-dependent that teacher-librarians had to make decisions individually. They tried hard to find the balance between protecting students from harmful resources and library ethics. Researchers and practitioners need focus more on finding where the balance is and how teacher-librarians deal with their ethical dilemmas.

This study aims to verify the mediating effect of social support in the relationship between online social relations service utilization(PC, mobile) and life satisfaction for middle-aged and Older Adults. For this purpose, the '2017 Digital Devide Survey' data collected by the National Information Society Agency was used, and among 2,300 middle-aged and Older Adults aged 55 or older, 1,488 people using the Internet were selected as the final analysis target. Then, using the structural equation, the mediating effect of social support was verified in the between online social relations service utilization and life satisfaction. As a result, it was verified that higher levels of mobile-based social relations service utilization have a positive effect on social support and life satisfaction. Also, it was confirmed that social support has a mediating effect in the relationship between the utilization of mobile-based social relations service and life satisfaction. However, the utilization of PC-based social relations services did not show to affect social support and life satisfaction. Therefore, the results of this study can be used as basic data for practical measures to increase the connection between mobile-based social relationship service education and social support promotion education for middle-aged and Older Adults. In addition, the study is meaningful in that it overcomes the limitations of measuring the use of online social relations services as one, and selects tools that are practically effective by dividing them into mobile and PC.

This study was conducted to confirm the effect on self-efficacy and critical thinking disposition by applying flip learning class to fundamental nursing practice education for nursing students. The study subjects were 42 people in the experimental group and 40 people in the control group who were allowed to participate in the study. Data analysis was statistically processed using SPSS/WIN 24.0 program. As a result of this study, the self-efficacy score of the experimental group who received the flipped learning class increased significantly immediately after class (t=3.49, p=.001) compared to before class, and 10 weeks after class (t=-0.75, p=.456), the effect persisted. The critical thinking disposition score of the experimental group increased significantly immediately after class (t=3.49, p=.001) compared to before class, and the effect persisted 10 weeks after class (t=0.11, p=.913). However, there was no significant difference in the academic self-efficacy and critical thinking disposition scores of the control group who received lecture classes. In other words, it was confirmed from the results of this study that fundamental nursing practice classes applied with flip learning are effective in improving self-efficacy and critical thinking disposition of nursing students. Based on this study, it is suggested that the application of flip learning method should be expanded in the major subject of nursing science.

Recentely, the military needs to apply various technologies for the improvement of teamwork. The government should take the non-face-to-face system due to the social interest of young military members. In this study we investigated collective cohesion by helping soldiers who have difficulty expressing their feelings and delivering messages while living in groups, or who are unable to adapt to group life due to psychological disorders such as relationship anxiety. We proposed the Multi-perspective Relationship Experience program as a new VR application. We showed feeling a sense of reality equivalent to the actual situation, interpersonal tension and social distance were significantly reduced, and communication, which was difficult to actually do, was naturally achieved. In addition, positive effects were confirmed on the sense of belonging and leadership among all participants. We will be effectively used in manpower management policies that improve the collective cohesion of soldiers and support the adaptability of the military environment in line with the rapidly changing social interaction method.

In this study, based on the theory of use and satisfaction, the motives of consumers who use Instagram accounts for luxury fashion brands were classified and the effect of the flow state experienced according to the motives on the purchase intention and the enjoyment was empirically studied. As a result of the analysis, the conclusions obtained through this study can be summarized as follows. First, it was found that the motive for using Instagram, a luxury fashion brand, had a significant positive effect on flow, followed by social interaction motive, informational motive, and enjoyment motive. Among the motivations for use, it was confirmed that the motivation for social interaction had the greatest influence on flow. Second, when using the luxury fashion brand Instagram account, the state of consumer flow induces positive emotions such as pleasure, which has a positive effect on purchase intention. Third, age, which is a characteristic of luxury fashion brand Instagram account users, had a significant positive moderating effect on the relationship between informational motives and flow, and had a significant negative effect with playful motives. Through the results of this study, we contributed to the flow of previous related studies by empirically showing the dynamics of consumer psychology related to the use of luxury Instagram accounts.

The objective of this study is to estimate the relationship between CO₂ emissions and both nuclear power and renewable energy generation, and compare the cost efficiencies of nuclear power and renewable energy generation in reducing CO₂ emissions in Korea. The results show that nuclear power and renewable energy generation should be increased by 1.344% and 7.874% to reduce CO₂ emissions by 1%, respectively. Using the estimated coefficients and the levelized costs of electricity by source including the external costs, if the current amount of electricity generation is one megawatt-hour, the range of generation cost of nuclear power generation to reduce 1% CO₂ emissions is $0.72~$1.49 depending on the level of external costs. In the case of renewable energy generation, the generation cost to reduce 1% CO₂ emissions is $6.49. That is, to mitigate 1% of CO₂ emissions at the total electricity generation of 353 million MWh in 2020 in Korea, the total generation costs range for nuclear power is $254 million~$526 million for the nuclear power, and the cost for renewable energy is $2.289 billion for renewable energy. Hence, we can conclude that, in Korea, nuclear power generation is more cost-efficient than renewable energy generation in mitigating CO₂ emissions, even with the external costs of nuclear power generation.

In this study, we aimed to understand the public opinion on COVID-19 vaccine. To achieve the goal, we analyzed COVID-19 vaccine-related Twitter posts. 45,413 tweets posted from March 16, 2020 to March 15, 2021 including COVID-19 vaccine names as keywords were collected. The 12 vaccine names used for data collection included 'Pfizer', 'AstraZeneca', 'Modena', 'Jansen', 'NovaVax', 'Sinopharm', 'SinoVac', 'Sputnik V', 'Bharat', 'KhanSino', 'Chumakov', and 'VECTOR' in the order of the number of collected posts. The collected posts were analyzed manually and automatedly through keyword analysis, sentiment analysis, and topic modeling to understand the opinions for the investigated vaccines. According to the results, there were generally more negative posts about vaccines than positive posts. Anxiety about the aftereffects of vaccination and distrust in the efficacy of vaccines were identified as major negative factors for vaccines. On the contrary, the anticipation for the suppression of the spread of coronavirus following vaccination was identified as a positive social factor for vaccines. Different from previous studies that investigated opinions about COVID-19 vaccines through mass media data such as news articles, this study explores opinions of social media users using keyword analysis, sentiment analysis, and topic modeling. In addition, the results of this study can be used by governmental institutions for making policies to promote vaccination reflecting the social atmosphere.

Purpose: Purpose: This study aimed to identify whether infection control practice would correlate significantly with the knowledge and attitude of infection control in the pre-, mid-, and postvisiting rounds among community-visiting nurses. Methods: A descriptive study was conducted based on the knowledge, attitude, and practice (KAP) model by administrating questionnaires during September-October 2020. A total of 65 nurses working for 15 community health centers in Seoul, South Korea were included. The questionnaires were developed based on the epidemiologic triangle model and comprised of 28 items on practice, 18 items on knowledge, and 10 items on attitude. Results: The infection control practice showed a mean of 88.9 (range, 0-100). The infection control knowledge had 89.2% on the host domain, 80.0% on the environment domain, and 74.8% on the agent domain (range, 0-100). The infection control attitude showed a mean of 39.5 (range, 0-50). Higher scores on the infection control practice are significantly correlated with the higher scores on the infection control knowledge about the host domain (p= .004) at the pre-, mid-, and post-visiting rounds. Higher scores on the infection control practice are significantly correlated with the higher scores on the infection control attitude at the mid- (p= .018) and postvisiting rounds (p= .028). Conclusions: The infection control practice by community-visiting nurses may be enhanced with increased knowledge and attitude levels of infection control at the mid- and post-visiting rounds. The enhancement should be included in the on-the-job education for community-visiting nurses.
