전지구적으로 진행 중인 기후변화 및 토지이용변화 등으로 강우량 및 유출량의 증가는 지속적으로 전망되고 있지만 현재 댐 시설물의 설계 및 유지관리에 대한 기준 및 제도에는 이러한 기후변화 영향에 대한 대책 및 적응방안이 포함되어 있지 않다. 기후변화로 인해 지속적 증가로 예상되는 피해에 대응하기 위하여 댐 수문학적 안전성 재평가가 필수적이고, 그에 따른 각종 위험도 및 취약성 평가가 함께 수반되어야 한다. 따라서 본 논문에서는 기후변화 시나리오를 적용하여 미래에 대한 댐의 수문학적 안전성 평가를 수행하고자 한다. 이를 평가하기 위하여 IPCC AR5 RCP 4.5/8.5시나리오를 사용하여 충주댐 유역의 가능최대강수량(PMP)와 가능최대홍수량(PMF) 산출 및 댐의 월류 및 여유고 확보 여부를 판단하였다. 그 결과를 사용하여 기후변화에 따른 전 기간(2040, 2070, 2100)에 대한 수문학적 안전성평가를 수행하여 향후 미래에 대한 안전성을 검토하고자 한다.

Museum storage has been a unique area for experts, such as curators and managers etc., is a part that requires attention among the recent changes in museums because of changes to a type that is being opened gradually to visitors. On the other hand, there is an increased the risk of a fire according to negligence etc. of visitors. Hence, appropriate measures for a fire protection system to respond to varying museum storage are required. This study examined the status of fire protection systems applied to museum storage visiting 40 domestic public museums with the support of the Ministry of Culture, Sports and Tourism, and a direction to install a fire protection system was presented by drawing cases of fire protection systems with less adaptability or poor management or excellent fire protection systems, and a direction for improvement was presented.

This study focused on the relationship among perceived social support from care teacher(institution staff), internal locus of control, and school adjustment of institutionalized children. This also examined the differences of perceived social support, internal thou of control, and school adjustment by gender and the duration in the institution. Participant were 119 fifth-and sixth-grade elementary school studens(58 boys, 61 girts). Perceived social support from care teacher, internal locus of control, and school adjustment were measured by self-reports of institutionalized children. The data were analyzed, in SPSS Win program, by Cronbach's α, T-test, Pearson Correlations, Simple Regression, Hierarchical Multiple Regression. As expected, results confirm that perceived social support was associated positively with internal locus of control and school adjustment. further, perceived social support also exerts indirect effects on school adjustment, mediated by internal locus of control. However, none of these variables differed by gender and the duration in the institution.

This study investigated early school adjustment of institutionalized and home-reared children. Subjects were 118 institutionalized (56 first and 62 second grade children; 66 boys and 52 girls) and 125 home-reared children (69 first and 56 second grade children; 65 boys and 60 girls) in Seoul. Data were analyzed with t-test and two-way ANOVA. Measures of school adjustment included relationships with leachers, relationships with peers, attitudes on school atmosphere, and observance of school regulation. Results showed that institutionalized children had lower scores than home-reared children in school adjustment, especially relationships with peer and observance of school regulation. For institutionalized children, there was a significant difference in attitudes on school atmosphere depending on grade. For home-reared children, there was a significant difference in school adjustment depending on sex.

This study examined teacher's perceptions of the psychosocial adjustment and problem behaviors of institutionalized children compared with home reared children. Data were collected from the teachers of institutionalized children in elementary and secondary schools. The majority of institutionalized children were regarded as not very much different from home reared children. Still, findings from this study lead to conclusions that institutionalization is likely to elevate children's risk for adjustment problems such as social withdrawal, peer violence, and academic failure. Findings that the ratio of institutionalized children attending school decreased with age lead to speculation that failure in psychosocial adjustment may lead to to dropping out of school. Finally, a practical framework for the optimal development of institutionalized children is provided, with emphasis on school-community based interventions.

This paper concerns developing a real time on-line light facility management system using internet and building a database system for control box and street light. Also, we designed the system to minimize the disparity with the conventional management system by referring to an old management ledger format. Thus, the proposed method may enable the system manager to administer the light facility efficiently and to reduce manpower and maintenance cost.

최근 지능재료 시스템 및 구조물(intelligentmaterial systems and structures)에 대한 연구가 전세계적으로 활발히 진행되고 있다. 이는 새로 창출된 연구개발 분야로서 현재와 가까운 장래에 국가기간 시설의 기능을 향상 시킬 수 있는 큰 잠재력을 갖고 있다. 지능재료 시스템 및 구조물은 시스템 성능의 극대화, 외부 환경변화에 대한 적응능력 그리고 유지비용의 최소화를 꾀할 수 있는 공학적 시스템 이다. 따라서, 이 지능재료 시스템 및 구조물에 대한 연구 개발 및 구현은 국가 기간 시설 재건축과 기능 향상에 커다란 이득을 가져올 수 있다. 빌딩, 다리, 수송로의 설계에 있어서 지능재료 시스템 및 구조물은 기능의 향상과 더불어 전체적 유지비용 의 감소를 가져올 수 있다. 지능재료 시스템은 형상기억합금 또는 압전재료와 같은 단일 재료를 말하기 보다는 이 재료들이 기능적으로 함께 통합된 시스템을 말한다. 기간 시설의 단순화와 시스템 건축비용의 감소 그리고 유지비용의 최소화를 위하여 지능재료 시스템 및 구조물은 설계와 건축에서 혁신적인 재료를 이용하여 구현되고 있다. 본 글에서 최근 미국 NSF(National Science Foundation) 워크샵에서 발표된 지능재료 시스템 및 구조물에 대한 비용을 바탕으로 이 기술이 국가 기간시설 첨단화 에 어떻게 적용되는가를 기술하고자 한다.

Climate changes have caused not only changes in the frequency and intensity of extreme climate events, but also temperature and precipitation. The damages on agricultural production system will be increased by heavy rainfall and snow. In this study we assessed vulnerability of crop cultivation facility and animal husbandry facility by heavy rain in 232 agricultural districts. The climate data of 2000 years were used for vulnerability analysis on present status and the data derived from A1B scenario were used for the assessment in the years of 2020, 2050 and 2100, respectively. Vulnerability of local districts was evaluated by three indices such as climate exposure, sensitivity and adaptive capacity, and each index was determined from selected alternative variables. Collected data were normalized and then multiplied by weight value that was elicited in delphi investigation. Jeonla-do and Gangwon-do showed higher climate exposures than the other provinces. The higher sensitivity to abnormal weather was observed from the regions that have large-scale cultivation facility complex compared to the other regions and vulnerability to abnormal weather also was higher at these provinces. In the projected estimation based on the SRES A1B, the vulnerability of controlled agricultural facility in Korea totally increased, especially was dramatic between 2000's and 2020 year.
