얕은사면 파괴는 지표로 침투하는 강우에 의해 주로 발생한다. 이는 지표수의 침투시 모관흡수력의 감소에 의한 포화깊이 증가에 의해 발생한다. 본 연구에서는 국내의 전형적인 화강풍화토를 대상으로 강우시 사면에서의 습윤영향을 분석하였다. 이를 위하여 filter paper와 tensiometer 실험을 수행하여 함수특성곡선을 산정하였으며, 그에 따른 함수특성곡선의 방정식을 추정하였으며, 기존에 사용되고 있는 Green & Ampt의 포화 깊이 추정식과 수치해석결과를 비교 분석하였다. 본 연구 결과, Green & Ampt모델에 의한 이론 해는 포화깊이를 과소 추정하였으며, 포화깊이가 증가함에 따라 사면안전율은 감소하는 것으로 나타났다. 특히 포화깊이가 약 1.2m이상부터 사면안전율은 현저하게 감소하는 것으로 나타났다. Surface failures of slopes in weathered soil are caused by infiltration due to prolonged rainfall. These failures are mainly triggered by the deepening of the wetting band accompanied by a decrease in suction induced by the infiltrating water. This paper reports trends of rainfall-induced wetting band depth in two types of weathered soils that are commonly found in Korea. Both theoretical and numerical analyses are presented based on the soil-water characteristic curve (SWCC) obtained using filter paper as well as tensiometer tests. It is found that the magnitude of wetting front suction plays a key role in the stability of slopes in weathered soils. Theoretical analysis based on modified Green and Ampt model tends to underestimate the wetting band depth for typical Korean weathered soils. It was also deduced that for Korean weathered soils, the factor of safety drops rapidly once the wetting band depth of 1.2 m is reached.

정유림,한삼성 대한근관절건강학회 2023 근관절건강학회지 Vol.30 No.3

Purpose: This study examines the health behavior and health-related quality of life (HRQOL) among married men andwomen, utilizing data from the Korean National Health and Nutritional Examination Survey, encompassing 4,217 subjects. Methods: A multiple regression model was employed to analyze the data. Results: Married men demonstrated asignificantly good relationship between HRQOL and perceived health state (β=.32, p<.001), while married womenshowed a similar relationship with perceived health state (β=.38, p<.001). Additionally, married men demonstratedsignificantly neutral relationship between HRQOL and perceived health state (β=.30, p<.001), as did the married women(β=.38, p<.001). Both married men (β=-.11, p<.001) and married women (β=-.08, p<.001) were found to experiencedepression. oreover, the HRQOL in married men was positively associated with private health insurance (β=.08, p=.001),and the same trend was observed in married women (β=.10, p<.001). Married men with unmet medical needs showeda negative association with HRQOL (β=-.08, p<.001), and married women with unmet medical needs showed a similarnegative association (β=-.12, p<.001). Furthermore, outpatient medical use(2 weeks) was negatively associated withHRQOL in both married men (β=-.07, p=.001) and married women (β=-.07, p<.001). Moreover, married women displayeda significant negative association between HRQOL and the prevalence of obesity(β=-.04, p=.048) and stress (β=-.05,p=.009) and a positive association with aerobic exercise (β=.04, p=.027). Conclusions: This study suggests that healthbehavior significantly influences the HRQOL among married men and women. The findings of this study can guidepolicymakers in developing strategies to improve health behavior and HRQOL within households.

여성가족패널(KLoWF)조사 4차년도(2011-2012) 자료를 활용하여 최종 2,120명의 기혼 여성을 선정하였으며, 남편지지와 결혼행복감 및 우울의 변수를 고려하였다. 남편지지는 남편과의 충분한 대화, 남편과의 견해 일치, 부부생활 만족도와 남편신뢰, 남편과의 문화생활, 운동과 봉사 및 공동체 참여, 시댁식구 만남, 친청식구 만남, 가사노동 만족도 그리고 돌봄 만족도로 11개의 문항을 고려하였다. 결혼행복감은 매우 불행하다 10점 리커드 척도로 측정되었고, 우울은 CES-D 10으로 측정되었다. 분석 결과, 인구사회학적 특성별 남편지지와 결혼행복감 및 우울은 유의한 차이가 있었다. 게다가 남편지지가 높을수록 결혼행복감 또한 높았으며 우울은 낮아지는 경향이었다. 구조방정식모형 결과, 남편인식은 우울에 직접적인 영향을 미쳤고, 결혼행복감을 매개로 우울에 간접적인 영향도 미쳤다. 부부활동과 가사분담 또한 우울에 직접적인 영향을 미쳤고, 결혼행복감을 매개로 우울에 간접적인 영향도 미쳤다. 그러나 부모방문은 우울에 간접적인 영향만 미쳤다. 남편지지 중 기혼여성의 남편에 대한 인식은 우리나라 기혼 여성의 우울에 가장 큰 영향 요인이었고, 부부활동, 부모방문 그리고 가사분담 순으로 나타났다. 이상의 연구 결과는 우리나라 기혼 여성의 우울을 줄이는 정책적 계획 설계에 도움이 될 것이다. The aim of this study was to investigate whether there is the relationship between husband support and depression mediated to connubial bliss in Korean married women. A total of 2,120 married women were selected from the database of the Fourth Korea Longitudinal Survey of Women and Families (KLoWF) in 2011-2012. By the structure equation model, among of the husband support, the husband awareness was regarded as the dominant factor related to depression in Korean married women. Then comes couple activity, visiting of parents and division of household labor in that order. This study suggests that husband support significantly associated with connubial bliss and depression in Korean married women. The above findings will help design policy plans to reduce the depression of married women in the nation.
