RI & RG are used in various field such as medical field, industrial field, agricultural and food&life field. The number of small nuclear facilities is on the increase. We need to take an interest in decommissioning of small nuclear facility and predict the occurring problem from facility decommissioning. Because of the relatively low radiation risk, the preparation of the small nuclear facility dismantling is often neglected. As the accident in Goiania, Brazil showed, the impact of the decommissioning of small nuclear facilities is not less than the large nuclear facilities although it may seem dangerless. Therefore, we analyzed the each institutional characteristics of the decommissioning of small nuclear facilities through foreign case study on this research. Also, we proposed several considerations on decommissioning such as reuse of facility and source, lack of space, stakeholder involvement and failures of protection. Through these study, we tried to make guideline of the small nuclear facilities decommissioning.

Objectives: The purpose of this study was to classify frail and non-frail elderly and to investigate health promoting behaviors and perceived health status in the elderly according to the type of residency. Methods: This was a descriptive study. Data collection was performed from June 15th, 2009 to August 2nd, 2009. The subjects were selected at D city in Korea. Data was analyzed by descriptive statistics, $x^2$-test, and ANCOVA test with SPSS/Win 15.0 program. Results: 20.8% of the elderly living at home and 49.2% of those living in institution were frail. Frailty of the elderly living in institution was severer than those living at home. Non-frail elderly according to the type of residency showed higher scores of health promotion behavior and perceived health status than frail elderly. The elderly living at home showed higher scores of health promotion behavior than those living in institution. Conclusions: In the comparison study between the elderly living at home and institution, ratio of frail elderly among the elderly living in institution is high and health promotion behaviors are deficient as well. Frail preventive program for the elderly is needed to develop and apply in consideration of these findings.

Recently according to increasement of the single family and dual-earner couples, the number of infants and young children stays on a long time to the childcare facilities. this is increasing the importance to improve the physical environment. However, the operating and maintenance costs of the national-public childcare facilities have taken effect of the unfair support issues of municipality's financial situation. Especially, because of the lack of the operating and maintenance costs of the facility and the shortage of facilities equipment maintenance repair costs, nursery operations and Maintenance items are needed to distribute appropriately. Therefore, this study is to estimate the importance to facility operations and maintenance items based on "Kindergarten and Childcare Facilities"presented at the Child Care Policy Study. we are expected to allocate appropriately of operation and maintenance cost of a limited budget. In particular, those can be considered for operation and maintenance cost about the National-Public Childcare Facilities and be determined to a safe and pleasant environment to kindergartens through the appropriate operations and maintenance support.

The national loss caused by the periodic livestock epidemic is very large. In addition, vehicle movement is the main cause of livestock epidemics in Korea. In this context, this study analyzed the relationship between the degree centrality of livestock facilities and the outbreak of infectious diseases. For this purpose, a livestock vehicle movement network was constructed using the facility entrance data provided by KAHIS. Afterwards, the centrality index was derived for each facility in the vehicle movement network and the mean centrality index of the epidemic and non-epidemic facilities were compared. The analysis results are summarized as follows. First, the degree centrality of epidemic facilities is significantly greater than non-epidemic facilities. As a result of the analysis of the entire period data and the period-based data, in most data, the degree centrality of facilities where livestock infectious diseases occurred was significantly greater than most non-occurrence facilities. Second, in the entire period data, the difference in degree centrality between the epidemic and non-epidemic facilities was smaller for HPAI than for FMD. On the other hand, no significant difference was found in the results of the analysis according to the divided period. The policy implications of the results are as follows. First, proactive management of facilities based on centrality is needed. Second, in the case of cloven-hoofed animal facilities, it is more urgent to introduce a management policy based on the degree centrality.

This study was conducted to analyze problems related to non-water-soluble sanitary products during the treatment of water regeneration centers in E.T.F. and S.T.F. at a time when the demand and supply of non-water-soluble sanitary products are increasing. As a result, the improvement plan of the W.R.C. should focus on pretreatment facilities. When replacing facilities in the future, various dust removers suitable for the facility's reality will be installed in the pretreatment of S.T.F., and it is proposed to link a bar-racks screen with a comprehensive treatment device or install a comprehensive treatment device for impurities alone in the pretreatment of E.T.F.. In addition, a microscreen screen must be installed on the front end of the excretory treatment unit. to separate non-water-soluble materials, and it is necessary to secure a maintenance space for the excretory treatment unit.

The aim of this research was to analyze the differences for the oral health status of the elderly people living in the long-term care facilities and the non-resident elderly. The study was conducted on 469 elderly people of the same age, gender and basic living conditions. Elderly residing in long-term care facilities had higher dental caries prevalence(p=0.019), DT(p=0.001), and MT(p=0.047) than non-resident elderly, and had lower FT(p<0.001) than non-resident elderly. The elderly living in facilities were 1.93 times more likely to be caries than non-residents, and 0.73 times more likely to have a filled tooth. The probability of denture use was 0.15 times for the maxillary and 0.13 times for the mandibular. The probability of denture needs was 5.61 times for the maxillary and 5.65 times for the mandibular. All of these results showed significant differences. As a result of this, it can be used as basic data for establishing oral health policy for oral health promotion of the elderly living in Long-term care facilities.

The purpose of this study is propose an Artificial Neural Network(ANN) model for the construction estimate of the public educational facility at conceptual stage. The current method for the preliminary cost estimate of the public educational facility uses a single-parameter which is based on basic criteria such as a gross floor area. However, its accuracy is low due to the nature of the method. When the difference between the conceptual estimate and detailed estimate is huge, the project has to be modified to meet the established budget. Thus, the ANN model is developed by using multi-parameters in order to estimate the project budget cost more accurately. The result of the research shows 6.82% of the testing error rates when the developed model was tested. The error rates and the error range of the developed model are smaller than those of the general preliminary estimating model at conceptual stage. Since the proposed ANN model was trained using the detailed estimate information of the past 5 years' school construction data, it is expected to forecast the school project cost accurately.

본 연구는 장래 유입수질 변화로 해수담수화(Desalination) 역삼투압(Seawater Reverse Osmosis) 공정의 전력비 예측 모델을 개발하고 별도의 해수담수화 추가공정이 필요한지 검토하였다. 플랜트 시설은 한번 설치되면 오랜 기간 운영이 되고, 주요 공정의 시설물 변경이 어려우며, 특히 해수담수화 시설의 경우에는 생활용수 및 공업용수를 수요자에 상시 공급함으로서 중간에 추가 시설물을 증설하거나 변경하기가 쉽지 않다. 따라서 해수담수화 시설의 계획 초기부터 현재의 유입수질 및 장래의 수질 변화를 예측하여 해수담수화 공정을 계획하는 것이 필요하다. 금회 검토는 해수온도 및 염분도 변화를 고려하여 서해에 위치한 대산산업단지 해수담수화 시설의 해수담수화 공정 전력비를 예측하였고, 입력 자료(온도 및 염분도)는 국가해양환경정보통합시스템(MEIS, Marine Environment Information System) 22년 과거자료(1997~2018년)를 이용하였다. 개발된 모형에 적용하여, 해수담수화에 필요한 전력비의 변화를 예측할 수 있으며, 이를 바탕으로 해수담수화 시설물 공정계획을 검토할 수 있었다. 금회 연구에서는 장래 수질변화 예측모형의 결과를 기반으로 해수담수화 시설물 공정을 제시하였다는데 의의가 있다.
