The purpose of this study was to investigate the effect of female college students’ academic, social, and emotional adaptation on suicidal ideation through the moderating effect of self-resilience. The participants of the study were 1,287 freshmen at S women’s university in Seoul. Reliability and confirmatory factor analysis results showed that the psychometric properties of the measures used in this study are favorable. Hierarchical multiple regression analysis results showed that female college students’ social and emotional adaptation negatively predicted their suicidal ideation, while academic adaptation was not a significant predictor when the degrees of social and emotional adaptation are controlled for. The result suggested that female students who adjust well socially and emotionally in college are less likely to involve in suicidal ideation. Furthermore, the negative effects of social and emotional adaption on suicidal ideation were moderated by the level of self-resilience. A high level of self-resiliece reduced the magnitude of the negative relationship of social and emotional adaptation with suicidal ideation while a low level of self-resilience strengthened the negative relationship between social/emotional adaptation and suicidal ideation. It is noteworthy that a low level of self-resilience coupled with a low level of social/emotional adaptation generated a high involvement in suicidal ideation. We discussed practical implications for preventing college students suicidal ideation by enhancing college life adaptation and self-resilience. 본 연구는 여대생의 대학생활에서의 학업적응, 사회적응, 정서적응이 자살생각에 미치는 영향과 이에 대한 자기탄력성의 조절효과를 살펴보고자 하였다. 이를 위하여 서울소재 S여대 2016학년도 신입생 1,287명으로부터 학업적응, 사회적응, 정서적응, 자기탄력성 및 자살생각에 대하여 조사하였다. 검사도구의 양호도를 살펴보기 위하여 신뢰도 분석 및 확인적 요인분석을 수행하였고 대학생활적응 변인과 자기탄력성이 자살생각에 미치는 영향 및 자기탄력성의 조절효과를 살펴보기 위하여 중다회귀분석을 수행하였다. 분석 결과 여대생의 사회적응, 정서적응 및 자기탄력성은 자살생각을 통계적으로 유의미한 수준으로 낮추어 주었고 자기탄력성은 사회적응 및 정서적응과 자살생각 간의 관계를 조절하는 것으로 나타났다. 본 연구는 여대생의 대학생활부적응이 극단적인 자살생각으로 흐르지 않도록 대처 방안에 대한 기초자료를 마련하였다는데 의의가 있다.

This study was performed to assess the degree of cognitive function impairment by MMSE performances and the effects. Data was collected by interviewers from 1,325 elderly people in Seogu, Daejeon city from June to July, 2002 and the collected data were analysed by SPSSWIN(ver 10.0). The results of analysis were as follows. The mean score of MMSE was 24.16±4.36 and significantly lower in female, in the older group and in the non-educated group. The subset score of MMSE were significantly lower in female group about each items: orientation in time and place, registration, attention/calculation, language except recall. And the scores were significantly lower in the older group and non-educated group about the all items of MMSE. In conclusion, sex, age and education showed significant effects on total and subset MMSE score. Cognitive function decline were higher in female sex, older age group and non-educated group. Therefore, those three factor are thought to be one of important risk factors for development of dementia because MMSE examination is useful instrument for evaluation of elderly dementia.
중학교 시기 학업성취도가 고등학교 시기 진로성숙도에 미치는 영향: 매개모형을 중심으로 한 혁신학교와 일반학교의 비교

목적 본 연구는 중학교 시기 학업성취도가 자기효능감과 학습에 대한 내적 동기를 매개로 고등학교 시기 진로성숙도에 어떤 영향을미치는지, 혁신학교와 일반학교에 대하여 분석하였다. 방법 이를 위하여 경기교육종단연구의 초등학교 4학년 패널 자료 중 5차년(2016)-7차년(2018) 자료를 활용하였다. 5차년도의학업성취도 변인, 6차년도의 자기효능감, 학습에 대한 내적 동기 변인, 7차년도의 진로성숙도 변인을 투입하여 SPSS MACRO 매개모형 분석을 수행하였다. 통제변인으로 성별, 가구소득, 가족형태, 부모애착 및 교육포부를 투입하였다. 결과 분석 결과, 진로자기이해의 경우 혁신학교에서는 중3 시기의 내적동기를, 일반학교에서는 자기효능감을 매개로 중2 시기의학업성취도가 고1 시기의 진로자기이해에 정적인 영향을 미쳤다. 진로계획성의 경우 혁신학교와 일반학교 모두 중2 시기의 학업성취도가 중3 시기의 자기효능감과 내적동기를 매개로 고1 시기의 진로계획성에 정적인 영향을 미쳤다. 내적동기의 매개효과는 혁신학교가 일반학교에 비하여 강하였다. 결론 분석 결과를 바탕으로 혁신학교의 교육효과성에 관하여 논의하였다. 특히 혁신학교에서의 학습경험이 학습의 내재적동기를통하여 진로성숙으로 이어진다는 것은 학업성취도만을 중시하는 교육풍토에서 혁신학교 정책이 새로운 교육적 대안이 될 수 있음이주요 논의점이다.

Fine suspended solids generated effluence from treatment process of mine drainage could destroy environment as the aesthetic landscapes, and depreciate water quality. Therefore, the purpose of this research is focused on process development applied the actual field for controlling fine suspended solids and heavy metals, and so lab-scale test was performed for inducement of basic data. The mine drainage used in this research was sampled in H mine located Jeongseon-gun, Gangwon-do. Concentration of suspended solid, arsenic, iron and manganese was exceeded the standard of contaminant limitation for the clean water, and particle size of suspended solid was less than 10 m as fine particle. Although hydraulic retention time of mine drainage for effective settling was required more than 6 hours, hydraulic retention time would be increased in winter season when the settling efficiency could be reduced because of viscosity decreasing. Moreover, installed inclination plate helped to increase settling efficiency of suspended solid about 48 %. Filtering media that was the most effective removal of suspended solids and heavy metal was decided granular activated carbon of 1~2 mm was the optimal size.

Fine suspended solids and soluble heavy metals generated from mine drainage could destroy environment as the aesthetic landscapes, and depreciate water quality. Therefore, this research is focused on process development applied the actual field for controlling fine suspended solids and heavy metals, and so that bench-scale tests were performed for field application based on advanced researches. The field of mine drainage in this research was in H mine located Taebaek-si, Gangwon-do. The inclination plates were mounted 2 kinds of arrangement (octagon and radial types) in circle type settling basin. The inclination plates could be helped to settle of suspended solids; decreased 34% of suspended solids and 50% of turbidity in effluent. Radial type of inclination plates showed the results that is more efficient to settle of suspended solids (average to 3.45 mg/L) compared to octagon type. In the experiments to decrease retention time of mine drainage in settling basin from 6 hrs to 1.5 hrs, suspended solid concentration was exceeded to 30 mg/L as the standard for suspended solid at 10 days after the operation under tha retention time of 3hrs and 1.5hrs. In the tests for filtration, granular activated carbons were indicated the better effective to filtering and absorption of fine suspended solid and soluble heavy metals than anthracite.
