The purpose of study was to evaluate the economic evaluation of Chuncheon curling stadium. In oder to estimate economic evaluation, benefit/cost ratio, net present value and internal rate of return were used. Additionally, in order to investigate the socio-economic spread effect, literature review and input-output analysis were used. The results of study were as follows. First, as a result of analyzing the demand for curling stadiums in Chuncheon, it was believed that the construction of the stadium will attract athletes from the Chuncheon region as well as athletes from Seoul, Incheon, Gyeonggi Province and North Chungcheong Province. Second, economic validity analysis showed that the initial investment did not make sense, but the players' training and competitions and the advantages of the potential experience of curling events for citizens in nearby areas, including Chuncheon, make the construction and operation reasonable. Third, as a result of the review of the social and policy validity of the curling stadium, the project to build a curling stadium in Chuncheon was secured with a policy validity as a public sports facility necessary for both professional and living athletes. Finally, the analysis of socio-economic spread effect of curling stadiums had shown that it would have a positive effect on the level of satisfaction of the general public as well as the discovery of elite athletes.

The purpose of this study is to examine relationship between social strains such as status strains and relational strains and adolescent suicidality by gender. As method, a self-report survey was completed by students (n = 819) from 3 middle schools in Seodaemun area, Seoul, Korea. Logistic regression analyses were conducted to identify factors associated with adolescent suicidality, t-test analyses were used to verify gender difference. Results show that male adolescents are more likely to experience abuse from their father, and school violence related to relational strains than female. Differences were found in strains for males and females contributing to suicidality; male are responsive to economic status, a dimension of status strain, whereas female are reactive to non-physical abuse from father, a type of relational strains. Non-physical school violence was appeared to be a significant factor influencing suicidality for both genders. Based on these findings, research draws implications for social work interventions. First, different approaches by gender are needed to prevent adolescent suicide in consideration of the tendency that men are status-oriented and women are relationship-oriented. Second, it is suggested to hire full-time school social worker to provide consistent social service for students. Third, intensive effort is necessary to reduce non-physical school violence.

This study attempts, using qualitative research methods, to identify a series of complex processes and mechanisms that turn the differences in the parents' education levels and occupational statuses into the gaps between their children's academic achievements. The highly educated parents with high occupational status are obsessed with top universities while the less educated parents with low occupational status tend to be less interested in educational capital. The highly educated middle-class parents themselves have strong educational aspirations. They also try to inspire educational aspirations and academic enthusiasm in their children by the early and deep involvement in a long-term educational strategy. They repeatedly teach their children to have aspirations toward higher professional status as well as a competitive attitude in academic performance. In contrast, the less educated working class parents do not emphasize the importance of high education and 'a good educational background' to their children. The differences in the educational aspirations and parenting practices between the two social classes primarily derive from their varying life experiences in the social structure. The middle class interviewees said that their obsession with 'a good education background' was closely related to their sense of fear that their children could fall from the middle class. In contrast to the middle class interviewees, the working class parents had no memories of painful experiences related to their lack of higher education. They claimed that they rarely ever felt inferior and that they rarely regretted their lack of high education. In addition, they did not believe that their lives were more difficult due to their 'low education'.

Statement Validity Analysis (SVA) is utilized in criminal investigations and the court to assess the credibility of given statements. During this procedure, the criteria for Criteria-Based Content Analysis (CBCA) are used to evaluate whether statements include the characteristics reflecting actual experiences about the event in question. Various studies had been conducted on the efficacy (classification rates) of CBCA criteria, yet the consistency of the findings was not investigated. In the current study, a meta-analysis was conducted with Korean CBCA studies reported from 2004 to 2020 (a total of fourteen studies). As a result, the total score of CBCA was found to successfully discriminate truth and fabrication. A significant positive (+) effect size was found with four criteria (3, 4, 10, and 12), all of which are classified as cognitive criteria. However, contrary to the underlying assumption for CBCA, criterion 18, classified as one of the motivational criteria, showed a significant negative (-) effect size. Meanwhile, moderator analyses were possible for eleven criteria (2~9, 12, 13, 15) and the results showed the significant effects of potential moderator variables such as the gender and status of the participants, study types and designs, number of raters, and publication status. The current results suggests that more careful attention is required to each criterion-especially the cognitive criteria-rather than the total CBCA score as well as the possible moderator effects in order to assess truthfulness of the statements. The implication, limitations, and suggestions for future studies were discussed.

Objectives: The COVID-19 outbreak has resulted in changes in the instructional methods used in kindergartens and daycare centers to prevent viral infections. This study aimed to investigate the changes in oral health care for children before and during COVID-19 and the perceptions of kindergarten and daycare center teachers about oral health care. Methods: The study subjects were 189 teachers of kindergartens and daycare centers in charge of children aged 3 to 5. The data for the analysis were collected through an online survey. Frequency analysis and the chi-squared test were used for statistical analysis. Results: Compared to before COVID-19, the frequency of tooth brushing after lunch, the number of oral health education and regular oral examinations, and the rate of childcare teachers' experiences with oral health education had decreased during COVID-19. In addition, educators in kindergarten and daycare centers responded that an oral health officer at a public health center was the most desirable oral health educator. Conclusions: During the COVID-19 pandemic, the oral health care of children in kindergartens and daycare centers has declined. Efforts are needed to restore it by educating people about oral hygiene care and oral health education, both at home and in kindergartens and daycare centers.

The purpose of this study was to determined the conceptual structure used by earth science teachers to classify metamorphic rocks as well as the criteria applied in the process of classifying metamorphic rocks. To this end, the researchers collected verbal data uttered in the process of classifying metamorphic rock using think-aloud from 21 earth science teachers in middle and high schools in Jeollabuk-do, Republic of Korea. The collected verbal data were analyzed using the semantic network analysis method, and the following results were obtained. First, in the process of classifying metamorphic rocks, earth science teachers classified them based on characteristics such as color, compositional minerals, and particle size, which can be generally observed in rocks, and foliation that appears in metamorphic rocks. Second, earth science teachers recognize the classification criteria for metamorphic rocks and focus on metamorphism such as contact metamorphism or regional metamorphism. However, there were cases where rocks were mistakenly classified through incorrect identification. Therefore, it is necessary to provide sufficient observational information about, and experience of, metamorphic rocks to enable earth science teachers to recognize and relate to the scientific process of identifying metamorphic rocks through the phenomena observed.

As the importance of the environment has been recognized worldwide, the need to calculate and reduce carbon emissions has been drawing an increasing attention throughout various industrial sections. Thereby the discipline of LCA (Life Cycle Assessment) involving raw material preparation, production processes, transportation and installation has been established. There is a clear research gap between the need and the practice for Korean Case of renewable energy industry, particularly wind power. To bridge the gap, this study conducted LCA research on wind power generation in the Korean area of Yeongdeok, an example of a domestic onshor wind power complex using SimaPro, which is the most widely used LCA system. As a result of the study, the energy recovery period (EPT) of one wind turbine is about 10 months, and the GHG emitted to generate power of 1 kwh is 15 g CO₂/kWh, which is competitive compared to other energy sources. In the environmental impact assessment by component, the results showed that the tower of wind turbines had the greatest impact on various environmental impact sectors. The experience gained in this study can be further used in strengthening the introduction of renewable energy and reducing the carbon emission in line with reducing climate change.

Je Baek-seok, who is well versed in poetry, calligraphy, painting, and sculpture, has established himself as the most outstanding painter and pavilion in the history of modern and contemporary Chinese art. During the Ming and Qing Dynasties, the art of the pavilion was developed greatly during the enlightenment period, with the emergence of many masters of the pavilion, including Jeonggyeong, Hwanghwangseokyeo, Oyangji, Jo Ji-gyeom, Hwang Mok-bo, and Oh Chang-seok. Je Baek-seok formed an original ritual under this social background. Je Baek-seok's tactics were formed by imitating works from the Hanwi period, and he harmonized Jin Kwon, Sopan, and Janggunin while using the penmanship of the Cheonbal Shinchambi based on the "Sasam Gongsanbi." In addition, by boldly using the Danipdo method, it is possible to use the human face as much as possible while fully exhibiting the artistry of calligraphy and adding to the atmosphere of gold stone. This paper mainly analyzed and reviewed the process of Je Baek-seok's transcription transformation and humanities practice from two aspects. First, it is planned to summarize the process of Je Baek-seok's transformation into a Jeonseo. Second, Je Baek-seok's humanities practice was analyzed. This paper will further understand Je Baek-seok's humanistic ideas and practical search by clarifying the originality of Je Baek-seok's engraving art with examples of Je Baek-seok's works, and it is believed that this will provide future scholars with learning paths and rich experiences.

The purpose of this study is to study jewelry designs presented to general consumers who seek new products and diversity. We would like to present a modular jewelry design with a structure and combination method that is distinct from jewelry in a multimodal replacement method that allows various product modules sold in the past to be worn interchangeably. Problems are likely to occur when a number of existing rather small parts are manufactured in a complex combination method, and difficulties may follow when consumers replace decorative parts and lose them in the process of assembling small fixture parts. Therefore, in order to reduce these problems, we try to make it different from jewelry products made with a simple and simple design so that it can be easily replaced and worn without the need for other coupling parts, and produced using the latest 3D printer (Rapid Prototyping). In this study, based on the experience and know-how gained while engaging in field work, it was possible to make a real object and focused on minimizing problems during the production process, and through this, time and economic loss can be reduced. The purpose of the study is to produce improved jewelry products by expressing more sophisticated and differentiated shapes by using 3D programs (CAD).
