A total of 594 reservoirs (17%), which are managed by KRC, equipped with earthquake-resistant facilities whereas remaining ones did not. In addition, reservoirs were placed without the effect of geological structures (i.e., fault and lineament). Therefore, development on technique for alleviating the potential hazards by natural disasters along faults and lineaments has required. In addition, an effective reinforcement guideline related to the geological vulnerabilities around reservoirs has required. The final goal of this study is to suggest the effective maintenance for the safety of earth fill dams. A radius 2 km, based on the center of the reservoir in the study area was set as the range of vulnerability impacts of each reservoir. Seismic design, precise safety diagnosis, seismic influence and geological structure were analyzed for the influence range of each reservoir. To classify the vulnerability of geological disasters according to the fault distribution around the reservoir, evaluation index of seismic performance, precise safety diagnosis, seismic influence and geological structure were also developed for each reservoir, which were a component of the vulnerability assessment of geological disasters. As a result, the reservoir with the highest vulnerability to geological disasters in the pilot district was analyzed as Kidong reservoir with an evaluation index of 0.364. Within the radius of 100km from the epicenter of the Pohang earthquake, the number of agricultural infrastructure facilities subject to urgent inspections were 1,180 including reservoirs, pumping stations and intakes. Four reservoirs were directly damaged by earthquake among 724 agricultural reservoirs. As a result of the precise inspection and electrical resistivity survey of the reservoir after the earthquake, it was reported that cracks on the crest of reservoirs were not a cause of concern. However, we are constantly monitoring the safety of agricultural facilities by Pohang aftershocks.

In 2008, 17, 596 dams and reservoirs are scattered across South Korea, and 17, 505 of them (99.5 %) are used for agriculture and 99.3 % are fill dam types. This study aimed to review literature related to the precise safety diagnosis system for agricultural reservoirs established by Korea Rural Community Corporation (KRCC) and analyze problems of its evaluation method. And then, it proposed ways to improve the system including a modified diagnosis system, which was applied to pilot districts in order to verify the utility. For assessment model development of agricultural reservoir, we reviewed status of precision safety inspections systems of agricultural reservoir. There are many problems such as assess agricultural reservoir not by sheet which used in fill dam but by block which used in concrete dam construction and diversion tunnel which main element in reservoir levee is treated as water intake facility. For considering diversion tunnel in reservoir levee, previous precision safety inspection systems which summed in separated phenomenon, separated element, separated site, separated facility was change to new systems which summed in site, phenomenon, element, and facility. Compared results of previous inspection system calculated total assessment index (Ec) with new system calculated total assessment index (Ec) are not show statistical difference.

This survey was conducted to assess the perception of hazards and washing behavior of vegetables of 500 housewives in Korea. The subjects were selected by the stratified random sampling method. The survey was performed using a structured questionnaire through telephone interviews by skilled interviewers. Most people have bought vegetables and fruits in the supermarket or (traditional) markets rather than stores, department stores, or direct transactions. Eighteen percent of the subjects felt vegetables were secure and were not concerned about safety. But $42.8{\%}$ were concerned about vegetable safety. The perceptions of vegetable-related hazards differed significantly by the respondent's socioeconomic characteristics. Higher concern about vegetable safety was reported by subjects with higher income, children, and who usually buy vegetables in supermarkets or department stores. Most subjects ($88.6{\%}$) perceived that residues of chemical substances such as pesticides were the most significant potential vegetable risk factor, followed by heavy metal, and pathogens. Housewives mainly rinsed vegetables in flowing-water ($85.2{\%}$ of subjects), 3${\~}$4 times ($63.8{\%}$ of subjects), and without detergent ($90.6{\%}$). Subjects believed that hazards decreased by blanching or boiling vegetables rather than washing. Subjects realized more or less correctly the removal rate of pesticide and pathogen through the washing and cooking processes. However, the removal rate of heavy metals was less than subjects thought it would be. Therefore, the scientifically assessed results on safety in the washing and cooking process should be opened to the public to provide the right-to-know and assure confidence in consumers.

범죄로부터 안전이 시민들에게는 일상생활에서 무엇보다 중요한 요인이라는 의식이 자리를 차지하면서 공적공간뿐만 아니라 사적장소에서의 안전에 대해 국가나 지방정부는 시민들의 안전을 보장할 책임이 있다.범죄는 시민들의 일상생활에서 공포와 두려움의 대상이 되기 때문에 이러한 범죄문제를 해결하지 못한다면 시민들의 삶의 질도 개선되지 못할 것이다. 범죄로부터의 안전한 지역사회를 만들기 위해서는 다양한 정책들이 구성되어야 하겠지만 그 중심에는 CPTED의 도입이 필수적일 수밖에 없다. CPTED는 도시공간의 물리적 환경설계를 범죄로부터 방어적인 구조로 변경 또는 적용함으로써 범죄와 범죄피해에 대한 공포를 차단하고 감소시켜 주는 이론이다. 본 연구는 지역사회의 안전을 위협하는 범죄에 대한 예방 방안 중의 하나로서 상가 및 쇼핑센터를 중심으로 한 범죄예방 진단프로그램을 개발하여 정책에 이용하고 나아가 지역주민의 안전한 삶을 보호하는데 연구의 목적을 두고 있다.

Objective : The paper aims to provide predictive coefficients via BIA for the assessment of body composition in children and adolescents to serve clinical as well as research purposes. Methods : Body composition via dual-energy x­ray absorptiometry (DXA) and bioelectric impedance as well as other anthropometric index were derived from meaurements on 1026 children and adolescents aged from 6 to 18 years from Beijing City. The best subset regression and principle component analysis were adopted to build the predictive coefficients with the logarithm of body composition via DXA as response variable. Results : Condition index ${\varphi}$ of fat-free mass multiple linear regression achieves 113.49 and 91.18 for males and females respectively, demonstrating severe multicollinearity among anthropometric indexes in children and adolescents. BIA predictive coefficients base on the best subset regression and principle component analysis boast a content predictive value for lean mass ($r^2$ = 0.9697 and 0.9664 for boys and girls respectively, p < 0.0001) and for Fat$\%$ ($r^2$ = 0.7705 and 0.6959 for boys and girls respectively, p < 0.0001). Conclusions : BIA method is applicable for the prediction of body composition for children and adolescents.

사회 안전과 관련해 범죄두려움의 중요성이 날로 더해가는 현실에서 민간경비의 활용이 범죄두려움에 어떠한 영향을 미치는 지에 대한 실증적 논의는 그 적실성이 높다 할 수 있다. 이에 이 연구는 범죄피해에 대한 위험인식과 그 두려움을 가중하는 대표적 요인인 지역 무질서가 범죄두려움에 영향을 미치는지 살펴보고, 지역 무질서와 범죄두려움의 관계에서 민간경비 유무의 영향력과 방향성을 검증해보았다. 이를 위해 한국 형사정책연구원에서 제공하는 전국범죄피해조사 2014년도 자료를 활용하고, STATA 13.0을 통해 위계적 회귀분석을 실시하였다. 그 결과, 민간경비 중 경비원의 경우 일반적 두려움에 주효과만을 나타냈으며, 지역 무질서와의 상호작용에서 유의미한 영향력을 갖지 못했다. 이와 달리 보안장치의 유무는 범죄두려움에 정적인 효과를 보였고, 이는 개인이 특수 잠금장치, 방범장치, 도난 경보시스템을 사용하더라도 여전히 높은 수준의 범죄두려움을 형성하고 있음을 뜻한다. 지역 무질서가 범죄두려움을 가중하는 상황에서 보안장치 유무의 조절효과는 통계적으로 유의미했다. 물리적 무질서가 높은 곳에서는 보안장치가 있는 경우, 보안장치가 없을 때에 비해 범죄두려움이 상대적으로 낮게 나타났다. 보안장치의 존재가 물리적 무질서가 높은 곳에서 범죄불안을 해소하는데 도움이 된다는 것을 의미한다. 이러한 결과를 바탕으로 효율성과 적합성 측면에서 보안장치의 설치를 유인할 수 있는 정책을 강구하고, 강화된 경비원의 역할과 책임, 재량을 논의하였다.

저수지 제체의 누수는 주로 세굴현상에 기인하며, 이 세굴현상은 주변의 토괴를 침식하여 결과적으로 제체의 파괴를 유발시키는 주된 요인이다. 따라서 누수구간의 탐지는 효과적인 제체의 유지관리에 필수적인 요소가 된다. 전기비저항 탐사는 저수지 제체의 안전진단에 가장 널리 사용되고 있는 물리탐사 방법으로 특히 세굴현상에 의한 누수구간의 탐지에 효과적인 것으로 알려져 있다. 하지만 기존의 전기비저항 탐사는 제체 마루에서 수행된 2차원 전기비저항 탐사자료의 역산 단면상에서 저비항대를 누수 위험 구간으로 해석하는 정성적인 단계에 머무르고 있다. 근자에 이르러 상시관측을 통한 전기비저항의 변화율을 이용한 해석방법이 제시되었지만 아직까지 제체의 안전도를 정량적으로 산출하는 기법에 관한 연구는 없는 실정이다. 제체내의 세굴현상이 진행됨에 따라 누수구간은 공극율이 증가하고, 공극율의 증가는 제체의 안전과 직결된다. 본 연구에서는 Archie의 경험식을 근거로 전기비저항 탐사에서 얻어진 건기전도도 자료를 제체부의 공극율로 변환하는 기법을 개발하였다. 또한 전기비저항 상시관측 자료를 이용하여 제체의 안전도 지수를 산출하는 방법론을 제시하고자 하였다.

Purpose: To test the reliability and validity of the Korean version of the Person-centered Climate Questionnaire-staff version (KPCQ-S) in long-term care institutions. Methods: A total of 297 staff in long-term care institutions including nine nursing homes (NHs) and 4 long-term care hospitals (LTCHs) were included. The KPCQ-S was developed following the WHO guidelines of the process of translation and adaptation of instruments. An internal consistency using Cronbach's ${\alpha}$ was tested for reliability. Exploratory factor analysis (EFA) was used to examine the construct validity. Convergent and discriminant validity were examined using Pearson correlation. Results: EFA demonstrated the construct validity of the 14-item KPCQ-S with three-factor solutions, specifically three factors (safety, everydayness, and community) in NHs and four factors (safety, everydayness, community, and comprehensibility) in LTCHs. Convergent validity was found in the correlation with the work satisfaction (r=.55). The KPCQ-S showed satisfactory internal consistency reliability (Cronbach's ${\alpha}=.91$). Conclusion: The KPCQ-S is found to be a reliable and valid tool for measuring staff perceptions of the person centeredness of long-term care environments.
