Purpose: In this study, potential demographic, social, and economic factors causing tuberculosis were identified, and eight cities in South Chungcheong Province were compared and analyzed with the IPA method. Method: The factors potentially affecting the prevalence of tuberculosis were categorized demographically, socially, and economically, and selected through brainstorming. Furthermore, potential factors affecting tuberculosis were derived using the revised IPA. Based on this analysis, areas with a potential risk of tuberculosis were classified, and the following policy implications were suggested. Result: The analysis found the three cities of Nonsan, Boryeong, and Gongju to have the highest potential risk of tuberculosis, and the frequency of potential risk factors in the above three cities to be 6 or more. Thus, an urgent policy response to prevent tuberculosis in these regions is required. Conclusion: According to the results of this study, it is necessary to take potential risk factors into account when promoting tuberculosis prevention policies and projects in South Chungcheong Province.

This study attempted to investigate the perception of safety of regular polish and gel polish and degree of nail damage. For this, a questionnaire survey and an experiment were performed against women in their 20-50s, and the results found the followings: In terms of effectiveness, safety and degree of nail damage, gel polish was higher than regular polish. In addition, moisture/sebum levels and trans-epidermal water loss (TEWL) decreased after the experiment. Specifically, such reduction was greater in gel polish. When the nail surface was observed by a scanning electron microscope (SEM) after polish removal, gel polish revealed severe nail damage. The above results confirm that gel polish is greater than regular polish in terms of influence on the degree of nail damage. Therefore, it is anticipated that the study results would be available as basic data in keeping nails healthy and beautiful.

This study empirically analyzed the effect of media literacy on the formation of the smart divide, which is a multi-faceted digital divide that occurs in the context of the use of smart devices. As a result, most of the factors of media literacy affect the establishment of social relations and social network through the use of smart devices, which, in turn, leads to the expansion of the range of informational and social activities. In addition, media literacy has a significant effect on the competence to evaluate the value of information acquired through the use of smart devices. Based on these results, there can be social disparity between those who have secured media literacy and those who do not from the perspective of informational and social benefits through the use of smart devices, which can function as a mechanism to generate the smart divide.

As social problems related to the digital divide are increasing, the elderly are facing various problems as an information alienated group. In particular, there is a need to strengthen the ability to critically understand and accept information. In this study, using the 2020 media panel survey, the effects of digital literacy in the elderly on critical thinking disposition of information were analyzed, focusing on the moderating effect of need for cognition. As a results of the analysis, it was confirmed that the operational and the information skill had a positive effect on the critical thinking disposition of information. Also, as a result of analyzing the moderating effect of NFC(Need for Cognition), it was found that NFC strengthens the influence of operational skill and reduces the influence of information skill. This suggests that the digital literacy education for the elderly needs to change from strengthening accessibility to improving information judgment.

최근 우리나라는 기후변화로 인한 이상기후 현상으로 호우 및 홍수 등에 의한 수재해를 예방하기 위한 설계빈도 적용방안 개발이 필요하다. 과거 지방하천의 일률적인 설계빈도의 적용 및 간접·주관적인 하천의 중요도와 지역특성에 대한 등급의 결정은 하천사업의 효율적 관리와 수행에 있어서 저해요소로 작용되어 왔다. 또한, 미래 기후변화 시나리오에 따라 하천의 중요도 및 계획 규모가 적절히 적용되어야 한다. 본 연구는 충청남도의 492개 지방하천에 대하여 유역특성(유역면적, 형상계수), 하천특성(하도경사, 수계 및 하천차수, 배수영향 구간), 이상강우 특성(이상강우 발생빈도, 시가화 침수면적)에 대한 현재 설계빈도에 대한 적절성을 평가하였다. 설계빈도에 대한 정량적 추정은 베이즈 이론을 활용하여 가중치를 산정한 후 최적분포형을 선정하였다. 최적분포형의 중앙값을 일반적인 지방하천의 설계빈도인 80년 빈도로 설정하고 상·하위 0.5%가 각각 100년, 50년 빈도로 가정하여 492개 지방하천을 평가하였다. 이상강우의 발생빈도와 시가화 침수면적에 따라 하천의 설계빈도가 높게 산정되는 것으로 분석되었다. 미래 기후변화 시나리오를 적용할 경우 현재 설계빈도(설계수명)에 대한 시나리오별 미래 재현기간을 산정하여 미래 설계빈도에 대한 위험도를 평가하였다. 13개 기후변화 시나리오의 대표농도경로 4.5와 8.5를 분석한 결과, 평균 3.2%, 12.8%의 위험도가 증가하는 것으로 분석되었다. 본 연구결과는 객관적인 지방하천의 적정 설계빈도 결정방안을 제시하였으며, 미래 계획홍수량 증가로 인하여 효율적인 토지이용이 제한될 것으로 예상됨에 따라 하천사업의 예산절감 및 우선순위 결정 등에 활용 가능할 것으로 판단된다.

In this paper analyzed the impact of innovation of CEOs of small and medium-sized companies, which are rapidly shifting to a digital economy, on corporate performance and how data literacy performs mediating functions. It was confirmed that innovation has a positive effect on corporate performance and that data literacy partially mediates the relationship between innovation and corporate performance. Transformational leadership shows a moderating effect in the relationship between innovation and corporate performance, and transactional leadership showed no moderating effect. Laissez-faire leadership has a moderating effect in the relationship between innovation and data literacy. These results show that innovation is an effective means of improving the organization's management performance, and are expected to awaken the importance of laissez-faire leadership and contribute to the establishment of management strategies.

This study tests the price discovery from US Treasury bond markets to Korean bond markets using the daily returns of Korean bond data (CD, 3-year T-note, 5-year T-note, 5-year corporate note) and US treasury bond markets (3-month T-bill, 5-year T-note 10-year T-bond) from July 1, 1998 to December 31, 2003. For further research, we divide full data into two sub-samples on the basis of the start-up of bond valuation system in Korean bond market July 1, 2000, employing uni-variate AR(1)-GARCH(1,1)-M model. The main results are as follows. First the volatility spillover effects from US Treasury bond markets (3-month T-bill, 5-year T-note, 10-year T-bond) to Korean Treasury and Corporate bond markets (CD, 3-year T-note, 5-year T-note, 5-year corporate note) are significantly found at 1% confidence level. Second, the price discovery function from US bond markets to Korean bond markets in the sub-data of the pre-bond valuation system exists much stronger and more persistent than those of the post-bond valuation system. In particular, the role of 10-year T-bond compared with 3-month T-bill and 5-year T-note is outstanding. We imply these findings result from the international capital market integration which is accelerated by the broad opening of Korean capital market after 1997 Korean currency crisis and the development of telecommunication skill. In addition, these results are meaningful for bond investors who are in charge of capital asset pricing valuation, risk management, and international portfolio management.

In this text, the author examines the aspects and characteristics of the three forms that were created and enjoyed when the upper-class nobles of Japan "combined(混淆)" waka(和歌) and Chinese poetry(漢詩) between the 10th and 17th centuries. The three forms are the "Collection of Japanese and Chinese poems for singing"(和漢朗詠), "A collection of Japanese and Chinese poems" (詩歌合), and the "Renku renga"(聯句連歌). "Collection of Japanese and Chinese poems for singing" appeared in the 10th century, "A collection of Japanese and Chinese poems" appeared in the 12th century, "Renku renga" appeared in the 14th century, and all three continued to influence the history of Japanese literature after that time. As the combination of literary Japanese and Chinese progressed, the gap between waka and Chinese poetry decreased until they finally combined to create a single work. That is, waka and Chinese poetry converged in one place in multiple ways: as a work that was appropriate to be recited("Collection of Japanese and Chinese poems for singing"), facing each other work against work in a competition("A collection of Japanese and Chinese poems"), and, in the end, they reached the point where they were interchangeable as lines making up long poems(長詩)("Renku renga"). The combination of literary Japanese and Chinese can be said to be the Japanese version of the common movement in East Asian literary history during the Middle Ages to make songs from one's own language flawless in Chinese poetry. Meanwhile, by examining the status changes that appeared as Chinese poetry paralleled, fought with, replaced, and combined with waka, we can find clues to explain the attitudes of the Japanese people on Chinese poetry during the period when the three forms existed, as well as the characteristics of Japanese Chinese poetry that appeared in response to that. The preferences not of "myself" but of the "audience," content and expressions that revere the period rather than the inner self of the poet, and the fact that it is a means for enjoyable pleasure rather than having the original characteristics of lyrical poetry for self-expression are all characteristics of Chinese poetry in Japan during the early and late Middle Ages period. These characteristics can be said to be the current that flows in the underbelly of the history of Chinese literature in Japan. This author believes that the key to discussing the history of Chinese literature in Japan during the Middle Ages period from the perspective of East Asian literary history can be found here.
