This study was conducted on 253 artists for a month from April 19, 2020 to study the influence and countermeasures of COVID-19. The analysis results are as follows. First, as a result of frequency analysis, the timing of the occurrence of COVID-19 and the period of the decrease in artist's artistic activities were consistent, and the subjective socioeconomic level perceived by the artist was degraded from COVID-19. Second, as a result of the multivariate variance analysis, the income level and employment environment of artists affected the variables associated with COVID-19. Third, as a result of the hierarchical analysis analysis, the income level and the socioeconomic level changes due to COVID-19, and concerns about COVID-19 infections, have been shown to have had a significant impact on the level of stress felt by artists. Fourth, as a result of qualitative research, the artist reported that he was experiencing economic and psychological difficulties due to the influence of COVID-19, and emphasized the need for policy support as a way to cope with them. We hope that the results of this study will be used as empirical data in the process of developing support systems and programs for artists experiencing economic constraints and social alienation due to COVID-19.

This study attempted to discover the problems related to the increasing book disposal trend within academic libraries by analyzing the disposal status over ten years and interviews with the librarians. The analysis utilized Korea Education and Research Information Service provided disposal information from 2010 to 2019. The academic libraries with more than 2 million books had disposed of the most number of books. This trend led to a distinctive decrease in the books' duplicate copies in terms of the collection composition. The librarians from the organizations, which conducted disposal more than three times and one massive removal within ten years, revealed in the interviews that they discarded many valuable duplicate books. They discussed the importance of digitizing high-value resources and also the limitation imposed by the copyright law. In conclusion, this study pointed out that book disposal can cause changes in the collection composition in the long run and suggested that academic libraries pay attention to these changes. The study also suggested evaluating the discarded books' values to guide the digitization efforts and count the number of books to include digital book use rights.

In traditional criminal cases, there is a limit to information collection because information on the subject of investigation is provided only with personal information held by the national organization of legal. Surface web-based OSINT(Open Source Intelligence), including SNS and portal sites that can be searched by general search engines, can be used for meaningful profiling for criminal investigations. The Korean-style OSINT workflow can effectively profile based on OSINT, but in the case of individuals, OSINT that can be collected is limited because it begins with "name", and the reliability is limited, such as collecting information of the persons with the same name. In order to overcome these limitations, this paper defines information related to individuals, i.e., equivalent information, and enables efficient and accurate information collection based on this. Therefore, we present an improved workflow that can extract information related to a specific person, ie., equivalent information, from OSINT. For this purpose, different workflows are presented according to the person's profile. Through this, effective profiling of a person (individuals) is possible, thereby increasing reliability in collecting investigation information. According to this study, in the future, by developing a system that can automate the analysis process of information collected using artificial intelligence technology, it can lay the foundation for the use of OSINT in criminal investigations and contribute to diversification of investigation methods.

Continuous subway line expansion over the years in Seoul metropolitan area has contributed to improved accessibility to public transport. Since public transport accessibility has a significant impact on housing decisions, quantitative analysis of correlation between housing prices and public transport accessibility is regarded as one of the most important factors for planning better housing policies. This study defines the reduction of traveling time resulted from the construction of new metro stations despite them not being the closest stations as 'Network Expansion Effect', and seeks to understand how the Network Expansion Effect impacts on housing prices. The study analyzes monthly rent data converted from upfront lump sum deposit, so called Jeonse in Korea, from 2012 to 2018, through 'A Modified Repeat Sales Model.' As a result, the effect of 'Network Expansion' on rental prices in Seoul has stronger during the period of 2017 to 2018 than the base period of 2012 to 2014, which suggests the 'Network Expansion' has a meaningful effect on rent. In addition, in comparison between the most and the least affected group of apartments by 'Network Expansion Effect', the most affected group has more price increase than the least affected group. These findings also indicate that different levels of 'Network Expansion Effect' have various influences on the value of residential real estate properties.

Start-up accelerators are a new type of investor that provide mentoring, education and seed capital to start-ups for a fixed duration and receive a certain stake in them in return. They help start-ups achieve successful commercialization. With increase in performance visibility, the number of private and public sector accelerators rose across domestic and international markets. Private sector accelerators are established and operated by private entities while public sector accelerators are established and operated by the government. Both play complementary roles that are becoming increasingly important to start-ups. Therefore, this study aims to examine the differences in major operational goals and investment determinants between private and public sectors and to understand their implications. The results show that the private sector prioritizes profit generation through the investment, while the public sector aims to contribute to the development of high-growth start-ups, and create region-specific and technology-specific start-up ecosystems. Additionally, both groups consider customer needs the most important determinant. Public groups are more conservative in investments and tend to place importance on objective indicators such as patents, partners, mentors, and co-founders. Conversely, private groups value the capabilities of founders and their ease of collaboration with accelerators. These findings can help start-ups get support from public or private accelerators more easily. It will also help public and private accelerators refine the criteria for selecting start-ups.

The purpose of this study was to understand the integration and clinical practice stress of nursing students and to understand the relationship with department satisfaction. Data collection was from June to July 2021. Data were collected through questionnaires consisting of scales of integration, clinical practice stress, and departmental satisfaction, targeting 3rd and 4th grade nursing students who have had more than one clinical practice experience. A total of 394 copies were analyzed using the SPSS program to analyze the data. As a result of the study, integration showed a positive correlation with department satisfaction (r=.412, p<.01) and a negative correlation with clinical practice stress (r=-.193, p<.01). The predictive factors affecting the department satisfaction of nursing students were integration (β=.406, p<.001) and admission motivation (β=.166, p=.006), which accounted for 20% of the total variance. Integration Performance It was confirmed that the motivation for entering the nursing department affects department satisfaction. In order to increase the department satisfaction of nursing students, it is thought that it is necessary to operate an integration promotion program and department adaptation program from the early stage of admission.

This study aims to investigate the effects of the ENACT project on promoting pre-service science teachers (PSTs)' views on the social responsibility of scientists and engineers. The ENACT project was designed to cultivate the social responsibility by integrating the theoretical framework of socioscientific issues (SSIs) education with problem-based inquiry approaches for the resolution of the issues. Thirty-two PSTs voluntarily participated in the project and completed the five stages over three months. Data was collected through a questionnaire to measure PSTs' view of the social responsibility of scientists and engineers (VSRoSE) and focus-group interviews. Results indicate that the PSTs presented statistically significant changes in their views of the social responsibility after the ENACT project. The mean scores of the five sub-dimensions of VSRoSE significantly increased. The interviews also supported that the PSTs had opportunities to seriously consider the social responsibility of scientists and engineers through epistemological exploration of science and technology (Cycle I), and problem-solving and action-taking (Cycle II). In particular, they agreed more on such responsibilities as consideration of societal needs and demands, pursuit of the common good, civic engagement and services using their expertise, communications with the public regarding potential risks, and participation in policy decision-making related to science and technology advances. Educational implications for SSI education and teacher education were suggested.

Hydrogen energy is emerging as an important means of carbon neutrality in the various sectors including power, transportation, storage, and industrial processes. Fuel cell power plants are the fastest spreading in the hydrogen ecosystem and are one of the key power sources among means of implementing carbon neutrality in 2050. However, high volatility in system marginal price (SMP) and renewable energy certificate (REC) prices, which affect the profits of fuel cell power plants, delay the investment timing and deployment. This study applied the real option methodology to analyze how the dual uncertainties in both SMP and REC prices affect the investment trigger price level in the irreversible investment decision of fuel cell power plants. The analysis is summarized into the following three. First, under the current Renewable Portfolio Standard (RPS), dual price uncertainties passed on to plant owners has significantly increased the investment trigger price relative to one under the deterministic price case. Second, reducing the volatility of REC price by half of the current level caused a significant drop in investment trigger prices and its investment trigger price is similar to one caused by offering one additional REC multiplier. Third, investment trigger price based on gray hydrogen and green hydrogen were analyzed along with the existing byproduct hydrogen-based fuel cells, and in the case of gray hydrogen, economic feasibility were narrowed significantly with green hydrogen when carbon costs were applied. The results of this study suggest that the current RPS system works as an obstacle to the deployment of fuel cell power plants, and policy that provides more stable revenue to plants is needed to build a more cost-effective and stable hydrogen ecosystem.

Vegetation is the basis for biodiversity conservation and sustainable development. In the Environmental Impact Assessment (EIA), which is the most direct and efficient policy measure to prevent degradation of nature, vegetation-related assessment has limitations as it is not based on quantitative and scientific methods. In addition, it focuses on the presence of protected species; hence, it does not take into account the role of vegetation as a habitat on a wide-area scale. As a way to overcome these limitations, this study aims to contribute to the quantification and advancement of future EIA on vegetation. Through the review of previous studies, core areas, connectivity, and vegetation condition were derived as the items to be dealt within the macroscopic aspect of vegetation impact assessment. Each item was spatially constructed using land cover maps and satellite imageries, and time series change analysis was performed. As a result, it was found that vegetation has been continuously deteriorating due to development in all aspects, and in particular, development adversely affects not only the inside of the project site but also the surrounding area. Although this study suggested the direction for improvement of the EIA in the vegetation sector based on data analysis, a more specific methodology needs to be established in order to apply it to the actual EIA process. By actively utilizing various environmental spatial data, the impact of the development on the natural ecosystem can be minimized.
