Rainfall Erosivity는 "강우침식인자"로 불리고 있지만, 호우사상이 토양침식을 일으킬 수 있는 잠재적인 가식성 인자로서 "강우가식성 지표"로 부르는 것이 타당하다. 본 연구의 목적은 연평균 강수량을 이용하여 연평균 강우가식성 지표를 추정하는 전국 단위 경험식을 개발하는 것이다. 기존에 학계에 보고된 경험식은 1971 ~ 1999년 기간의 31개 지점으로부터 도출된 경험식이 있으나, 2000년대 이후의 강우사상을 포함하고 있지 않다. 이에 본 연구에서는 1981 ~ 2020년 기간의 60개 지점에 대한 기상청 강우자료를 이용하였으며 선행연구자들이 각각 산정한 연평균 강우침식인자를 토대로 새로운 강우침식인자 추정식을 개발하였다. 또한, 역거리 방법으로 등강우침식도를 작성하여 1981 ~ 1990년, 1991 ~ 2000, 2001 ~ 2010년, 2011 ~2020년의 각 10년 주기별 강우침식인자의 지역별 분포를 비교하였다. 연구 결과 국지성 집중호우로 인해 연평균 강우가식성 지표값의 지역별 편차가 심하게 나타나는 것을 알 수 있었다.

본 연구는 광역시와 광역도 간의 개인적 요인과 건강수준 정도가 우울경험 여부에 영향을 미치는 변수의 중요도를 파악하고자 시도되었다. 본 연구의 자료는 질병관리청의 2021년 지역사회건강조사 데이터를 활용하였다. 광역시의 데이터는 4,602건을 이용하였고, 광역도는 19,545건의 데이터를 이용하였다. 자료 분석에 활용된 빅데이터는 R 4.3.0 for Windows를 활용하여 단어 빈도 분석과 machine learning기법인 Random Forest분석을 실시하였다. 연구결과, train 데이터와 test 데이터의 과적합(overfitting)의 문제는 발생하지 않았으며, machine learning 기법의 분류모델은 약 94% 수준으로 나타났다. 분석 결과 광역시와 광역도 간의 우울경험여부에 미치는 중요도가 각각 다르게 나타났다. 두 지역의 시민에게 미치는 우울경험의 원인을 다르게 접근함으로써 보다 더 효율적인 정책수립이 가능 할 것으로 판단된다.

대부분의 발달장애를 돌보는 어머니의 양육경험 속에는 스트레스로 인한 부정적 정서 및 우울증을 포함하지만, 어떤 어머니들은 장애자녀로 인해 가족 및 사회적 친화력을 높이고 긍정적인 정서경험을 통해 자신 및 가족의 삶의 질을 향상시켜 나간다. 본 연구는 발달장애를 돌보는 중년기 어머니들의 양육경험과 우울증의 상관관계에 있어 어머니의 자기자비와 중년기의 신체 및 심리적 특성에 대한 자기이해가 어떠한 영향을 미치는가에 대해 탐색하고자 한다. 연구수행에 필요한 자료 수집을 서울, 경기를 포함한 전국에 사는 발달장애 중년기 어머니 700명을 대상으로 하며, 자료는 SPSS PC+ Ver 28을 활용하여 빈도분석과 주요 변수에 대한 기술통계를 실시하고, 변인 간 상관관계, 회귀분석을 실행한다. 본 연구의 의의는 발달장애인 자녀를 돌보는 어머니의 양육 스트레스를 줄이고 건강한 가족회복을 위해 어머니의 자존감을 향상시킬 수 있는 자기자비의 역할과 중년기에 대한 자기이해를 강화하도록 도울 수 있는 장애인 가족지원 정책 및 사회 서비스 개발에 기여하고자 한다.

The present study aimed to investigate the rate of unmet healthcare needs for elderly over the age of 65 years, as well as analyze the relevance between employment status and unmet healthcare needs due to financial reasons. With regard to the study method, a logistic regression analysis was performed to investigate the correlation between employment status and unmet healthcare needs due to financial reasons, targeting 5,528 subjects over the age of 65 years. The results showed that the rate of unmet healthcare needs was 18.9%, in which the rate of unmet healthcare needs due to financial reason was 8.1%. The rate of unmet health needs was higher for temporary workers(ORs=1.75) than for retirement workers. However, the rate of unmet healthcare needs caused by financial reasons was higher among day workers(ORs=1.92). In conclusion, in order to prevent unmet healthcare needs for senior Korean patients, it is necessary to not only improve the income security system for the elderly, but also improve the occupational form and level of income of these economically active citizens, considering the increase in average life expectancy. Moreover, it is also necessary to reinforce health insurance coverage systems for settling medical expenses.

The purpose of this study is to verify the moderating effect of self-esteem between emotional trauma and internet smart phone addiction of adolescents. For this purpose, this study confirmed moderating effect by setting emotional trauma as predicting variable, self-esteem as moderating variable and internet smart phone addiction as dependent variable. The study conducted a questionnaire survey on 645 middle school students regarding emotional trauma, self-esteem and internet smart phone addiction. The results of this study are as follows; first, emotional trauma had negative correlation with self-esteem and positive correlation with internet smart phone addiction. Self-esteem had negative correlation with internet smart phone addiction. Second, as the result of hierarchical regression analysis, there was an interaction effect of emotional trauma and self-esteem on internet smart phone addiction. The meaning of this study are as follows; first, it is proved that one of the causes of internet smart phone addiction is adolescent's emotional trauma and, second, it is proved that the intervention of self-esteem is required to reduce the negative effect of adolescent's emotional trauma. That is, it turned out that self-esteem moderated the relationship between emotional trauma and internet smart phone addiction.

The purpose of the study was to understand the various aspects of learning experiences of Korean university students on K-MOOC. Analyses on the major motivation of the enrollment in a certain MOOC class, the actual learning experiences in the class and the perception of the achievement of the class were the three main foci of the current study. The study employed inductive content analysis as a major analysis tool. Reflective journals from 94 students who enrolled in K-MOOC classes were collected and analyzed at the end of the semester. The result of this study indicated that most of students selected the specific K-MOOC classes based on their general interests on the topics the class offered. Other factors such as intellectual curiosity, practical reasons for their study or work and popularity were also influential on the selection of MOOC classes. Watching videos, taking quizzes and taking tests were the three major sources of the students' satisfaction. Most students felt that K-MOOC is technically satisfactory. However, some students reported on simple errors and absence of advanced functions in the platform. Students perceived positively on their academic achievements of obtaining knowledge(remembering and understanding), attitudes (receiving), and skills through K-MOOC. This study ultimately showed a new awareness of learning experiences around K-MOOC from the perspective of the students. Future research is needed to understand the relationships between the students' learning experience and the students' performance in MOOC classes.

The purpose of this study is to identify the effects of entrepreneurship experience and education on entrepreneurship intention, and to test the moderating effect of gender on these relationships. To test the hypothesis, we used GETR(Global Entrepreneurship Trend Report) data that was collected by Korea Entrepreneurship Foundation and was consisted of 40,388 data collected from 2,000 people in 20 countries. First, entrepreneurship experience and entrepreneurship education have significant influence on entrepreneurship intention. Second, gender moderating effects on these relationships were found to have a significant effect on the relationship between entrepreneurship education and entrepreneurship intention. Specifically, the positive effect of entrepreneurship education on entrepreneurial intention was found to be stronger for women than for men. Finally, the analysis of the three-way interaction effect of the social protection confirmed that the positive relationship between entrepreneurial experience and entrepreneurial intention was stronger for women than for men, and this effect was found to be higher in the high social protection group. In other words, women with entrepreneurial experience are more likely to increase their entrepreneurial intentions when they are more aware of social protection than men.

Korean unwed mothers and their families often experience discriminatory and unfair treatment in their everyday lives. However, there has been little research examining discrimination against unwed mothers and its effects on these women's lives. Therefore, further studies are needed to identify and assess types and degree of discrimination against unwed mothers. This study aims to investigate and develop a reliable and valid measurement scale of experiences of discrimination for Korean unwed mothers. For developing the scale, the researchers constructed a concept and sub factors, and the pre-scale of 75 items of discrimination experiences of unwed mothers by conducting a literature review and focus groups interviews, Validity and reliability of the scale were tested by carrying out an item quality analysis, a exploratory factor analysis, a correlation analysis, a criterion validity test and a reliability analysis, The scale of 21 items was constructed with three dimensions. This study is significant that it provides the scale of discrimination for Korea unwed mothers with high reliability and validity to identify and verify types and degree of discrimination experiences of unwed mothers.
