  • During pandemic period, college students lost lots of such academic opportunities as extra-curriculum social activities, contact classes, and friendly socializing in university campus area, etc. Previous many studies have shown that physical environment has certain relevance on the well-being of human-beings. Recent public statistics on mental health had shown an increase in psychological distress and a decrease in college students and people's well-being during the lockdown in response to the Covid-19 pandemic. However, there were little evidence on what the college students in dormitory suffered from COVID-19 incident in relation with their physical environment. The purpose of this study is to investigate the relationship between environmental factors and psychological well-being of dormitory students in university campus. In order to explore the impact of physical environment on students' psychological well-being, survey instrumentation consisted of 25 indices were employed to measure the level of awareness to each index. A Chi-square analysis on individual characteristics of 200 students found that number of students living in single dwelling unit was statistically significant to maintain their psychological well-being, except for number of students living in each dwelling unit (χ2 =128.92, p= .004). Pearson correlation analysis also found that there exists statistically significant relationship between psychological well-being of students and environmental factors. Further, stepwise multiple regression analysis revealed that the most prime predictor for psychological well-being of students residing in dorm was "use of furniture" (β= .281), implying careful design, lay-out and easy-access to interior furniture by facility planner. The study also demonstrated that as the level of positive perception of physical environmental features rose, overall psychological well-being of students also responded positively at specified rate. Finally, the findings reinforce a solid evidence that carefully well-coordinated physical environments play an important role in maintaining emotional stability of college students in dorm even in pandemic period.

  • The aim of the article is to investigate socio-political processes in Ukraine on the basis of institutional and behavioral approaches, in particular their regulatory and informational support. Methodology. To determine the nature and content of sociopolitical processes, the following approaches have been used: 1. Institutional approach in order to analyze the development of Ukraine's political institutions. 2. The behavioral approach has been used for the analysis of socio-political processes in Ukraine in the context of political behavior of citizens, their political activity which forms the political culture of the country. Results. The general features of the socio-political situation in Ukraine are as follows: the formed model of government, which can be conditionally described as "presidential"; public demand for new leaders remains at a high level; the society has no common vision of further development; significant tendency of reduction of real incomes of a significant part of the society and strengthening of fiscal pressure on businessmen will get a public response after some time. Increasing levels of voice, accountability, efficiency of governance and the quality of the regulatory environment indicate a slow change in the political system, which will have a positive impact on public sentiment in the future. At the same time, there has been little change in the quality of Ukraine's institutions to ensure political stability, the rule of law and control of corruption. There are no cardinal changes in the development of the institution of property rights, protection of intellectual rights, changes in the sphere of ethics and control of corruption. Thus, Ukraine's political institutions have not been able to bring about any change in the social-political processes. Accordingly, an average level of trust and confidence of citizens in political institutions and negative public sentiment regarding their perception and future change can be traced in Ukraine.

  • 청소년기는 자아정체성이 확립되지 않아 스트레스를 이겨내는 능력인 자아탄력성이 중요한 시기이다. 문화예술교육은 청소년의 자아탄력성에 다양한 영향을 주고 있어 학교문화예술교육과 사회문화예술교육에서 청소년들의 상황에 적절한 교수학습 방법을 활용하고 있다. 문화예술교육 효과의 자신 이해는 청소년 자아탄력성의 감정통제, 활력성, 대인관계, 낙관성, 호기심에 모두 유의한 영향을 주고 있는 반면에 문화예술교육 효과 중 정서적 안정은 청소년 자아탄력성의 모든 요인에 유의한 영향을 미치지 못한 것으로 분석되었다. 따라서 청소년의 자신에 대한 이해와 자기 계발을 위하여 더욱 실질적인 프로그램으로 진로 탐색 기회 등을 제공하는 방안을 마련하여야 한다. 그리고 문화예술교육은 청소년들의 개인적 성향을 타인과 좋은 유대관계를 유지하고 높은 자신감을 가지며 안정되고 성숙한 생활의 넓은 영역에서 역할 수행할 수 있는 융합적 연구가 이루어져야 할 것이다.

  • Purpose: This study investigated the vulnerability to human immunodeficiency virus (HIV) infection and associated factors among married women in northwest Ethiopia. Methods: A community-based cross-sectional survey (n=657) was conducted from April 1 to 15, 2020, in Metema District, northwest Ethiopia, in four randomly selected kebele administrations (the lowest level of local government). The inclusion criteria were married women aged ≥18 years residing with their husbands. Logistic regression analysis was conducted to identify factors associated with married women's vulnerability to HIV infection. Results: Participants were on average 33.70±9.50 years and nearly one-fourth (n=148, 22.5%) were identified as vulnerable to HIV infection (i.e., experienced sexually transmitted disease symptoms or an extramarital affair of either spouse within the past 12 months). Only 18.9% reported sexual communication with their husband. Respondents who did not discuss the risk of HIV infection with their husbands had fivefold odds of vulnerability (adjusted odds ratio [AOR], 5.02; 95% confidence interval [CI], 1.43-17.5). Those who did not have premarital sex (AOR, 0.20; 95% CI, 0.05-0.77) had no worries about HIV infection (AOR, 0.27; 95% CI, 0.08-0.94), sufficient income (AOR, 0.56; 95% CI, 0.16-0.86), and less than four children (AOR, 0.69; 95% CI, 0.50-0.97) had decreased odds of being vulnerable to HIV than their counterparts. Conclusion: Not discussing risk of HIV infection with husband was a major factor of vulnerability to HIV infection as was premarital sex, worry about HIV, income, and number of children. Measures to strengthen couple's sexual communication and support economical stability is important for decreasing HIV vulnerability.

  • 초고령사회 진입을 앞두고 우리나라는 노인인구의 급속한 증가로 노인주거 문제가 중요한 이슈로 떠오르고 있다. 특히, 노인인구의 살던 곳에서 노후 맞이하기(Aging in Place: AIP)는 노인복지의 지향점으로 꾸준히 제시되고 있다. 이에 본 연구는 2008-2020년 고령화연구패널 자료와 임의효과 로지스틱 회귀분석 모형을 사용하여 자녀와의 교류가 노인 주거이동에 미치는 영향을 실증 분석하였다. 연구 결과는 다음과 같다. 첫째, 자녀와의 교류가 수도권과 비수도권에 무관하게 노인인구의 주거이동을 촉진시킬 확률이 높다는 점을 발견하였다. 둘째, 연령이 증가할수록 자녀와의 교류는 노인인구의 주거이동을 더욱 촉진시키는 경향을 보였으나, 그 영향력은 연령과 변수에 따라 일정치 않게 나타났다. 셋째, 자녀와의 교류 변수들의 상호작용 효과를 통해 노인인구의 주거이동을 더욱 촉진시킬 가능성이 높아짐을 확인하였다. 본 연구는 자녀와의 교류가 노인인구의 주거 안정성을 증진 시켜 독립적인 정주 환경을 구성할 수 있는지, 즉 노인인구의 살던 곳에서 노후 맞이하기 측면에서 정책적 시사점을 제시한다.

  • 환경·사회·지배구조(ESG) 성과가 투자자의 의사결정에 미치는 영향이 커지고 있다. 과거 기업의 재무적 성과에 집중하던 투자자의 시선이 기업을 둘러싼 이해관계자의 이익이라는 비재무적 성과로 확장하고 있는 것이다. 이런 배경에서 본 연구는 기업의 비재무적 성과인 ESG 성과가 기업위험에 미치는 영향을 분석하기 위해 한국기업지배구조원이 평가하는 기업을 대상으로 패널회귀분석을 실시하였다. 분석 결과 ESG 성과는 세 가지 기업위험(체계적위험, 비체계적위험, 총위험) 모두에 대해 음(-)의 영향을 미치고 있어 이해관계자이론과 위험관리이론을 지지하는 결과를 나타냈다. 본 연구의 시사점은 첫째, ESG는 비체계적위험 뿐만 아니라 광범위하고 무차별적인 체계적위험도 감소시키고, 둘째, 투자자는 ESG 투자를 집행함으로써 투자포트폴리오의 위험을 감소시킬 수 있고, 셋째, 기업은 ESG 경영의 보험기능을 활용함으로써 부정적인 상황에서도 안정적인 재무성과를 영위할 수 있으며, 마지막으로, 정부는 합리적인 ESG 관련 규제를 통해 기업의 재무적 건전성을 제고하면서 금융시장의 안정성을 높일 수 있다는 것이다.

  • Purpose: First, this paper suggests an alternative approach to find optimal portfolio (stocks, bonds and ESG stocks) under the maximizing utility of investors. Second, we include ESG stocks in our optimal portfolio, and compare improvement of welfares in the case with and without ESG stocks in portfolio. Methods: Our main method of analysis follows Brennan et al(2002), designed under the continuous time framework. We assume that the dynamics of stock price follow the Geometric Brownian Motion (GBM) while the short rate have the Vasicek model. For the utility function of investors, we use the Power Utility Function, which commonly used in financial studies. The optimal portfolio and welfares are derived in the partial equilibrium. The parameters are estimated by using Kalman filter and ordinary least square method. Results: During the overall analysis period, the portfolio including ESG, did not show clear welfare improvement. In 2017, it has slightly exceeded this benchmark 1, showing the possibility of improvement, but the ESG stocks we selected have not strongly shown statistically significant welfare improvement results. This paper showed that the factors affecting optimal asset allocation and welfare improvement were different each other. We also found that the proportion of optimal asset allocation was affected by factors such as asset return, volatility, and inverse correlation between stocks and bonds, similar to traditional financial theory. Conclusion: The portfolio with ESG investment did not show significant results in welfare improvement is due to that 1) the KRX ESG Leaders 150 selected in our study is an index based on ESG integrated scores, which are designed to affect stability rather than profitability. And 2) Korea has a short history of ESG investment. During the limited analysis period, the performance of stock-related assets was inferior to bond assets at the time of the interest rate drop.

  • Background: As social problems due to the acceleration of the aging era and the increase in the elderly population are becoming serious, virtual reality (VR)-based healthcare is emerging as an approach for preventing and managing health issues. Objects: This study used validity and reliability analyses to examine the clinical efficacy that is, the clinical value and usability of a novel VR cognitive evaluation system index that we developed. Methods: We developed a VR cognitive evaluation system based on motion recognition analysis evaluation for individuals aged 65 to 85. After conducting the Korean version of the Mini-Mental State Exam (K-MMSE) cognitive evaluation, the evaluation score was verified through correlation analysis in the VR cognitive evaluation system. To verify the construct validity of the two groups, the Global Deterioration Scale (GDS) grades were categorized into a normal cognitive group (GDS grade 1) and a cognitive impairment group (GDS grades 2 and 3). The data were measured twice to determine the reliability between the two measurements and assess the stability and clinical value of the evaluation system. Results: Our evaluation system had a high correlation of 0.85 with the widely used K-MMSE cognitive evaluation. The system had strong criterion-related validity at the 95% confidence interval. Compared to the average score of GDS grade 1 in the VR cognitive evaluation system, the average score of GDS grades 2 and 3 in the VR cognitive evaluation system was statistically significantly lower while also having strong construct validity at the 95% confidence interval. To measure the reliability of the VR cognitive evaluation system, tests-retests were conducted using the intraclass correlation coefficient (3,1), which equaled 0.923 and was statistically significant. Conclusion: The VR cognitive evaluation system we developed is a valid and reliable clinical tool to distinguish between normal cognitive status and mild cognitive impairment.
