In terms of both quality of rural lifestyle and cultural awareness, the importance of community facility is being emphasized. Nevertheless, by occasion of graying, population outflow and revenue loss, rural society faces the erosion of community. For these reasons, government is promotion an community space construction project on rural areas which is lack of community facilities. Whereas the projects are just one off thing not include upkeeping, so lots of functional overlapping community facilities are formed in same place. In this study has classified rural community facility remodeling element and designed rural community facility evaluation system of each elements. In order to implement of purpose, it has categorized community remodeling index in rural area by literature analysis and site survey. For setting remodeling rating system, this study analysed preceding research data and conducted a Delphi survey of 30 experts. As a result, this study deducted 29 categories of community remodeling index and 21 categorizes of remodeling rating clause. Taking this result, this study progressed case study on seonheul-ri in Jeju. Implications, limitations and future research directions are presented. It would be groundwork for remodeling system development in rural community facility.

열화학적인 수소 생산 공정 중 하나인 S-I Cycle은 요오드와 황을 이용한 수소 생산 공정으로써 물 분자로부터 수소분자를 얻어내는 순환 공정이다. 수소 생산 공정에 열을 공급하고자 하는 초고온 원자로(VHTR; Very High Temperature Reactor)는 원자로에서 수소 생산 공정으로 방사능 없이 안전하게 열을 전달하기 위하여 중간열교환기(IHX; Intermediate Heat Exchanger)가 필요하다. 본 연구에서는 수소 생산공정과 초고온 원자로간의 중간 열교환 공정을 모사하여 운전압력 및 작동 유체의 변화에 따른 중간 열교환기의 효율을 계산하고 가장 경제적인 중간 열교환기를 설계하기 위한 공정 조건을 도출하였다. SI Cyclic process is one of the thermochemical hydrogen production processes using iodine and sulfur for producing hydrogen molecules from water. VHTR (Very High Temperature Reactor) can be used to supply heat to hydrogen production process, which is a high temperature nuclear reactor. IHX (Intermediate Heat Exchanger) is necessary to transfer heat to hydrogen production process safely without radioactivity. In this study, the strategy for the optimum design of IHX between SI hydrogen process and VHTR is proposed for various operating pressures of the reactor, and the different cooling fluids. Most economical efficiency of IHX is also proposed along with process conditions.

Purpose: The purpose of this study was to compare the effects of meatal care with 10% betadine or with normal saline on the incidence of urinary tract infection (UTI) for elderly patients with indwelling urinary catheter in the ICU. Method: A quasi experimental design with non-equivalent control group was used. The 37 patients who participated in this study were 65-year-old or older. Patients in the saline group (n=20) received meatal care with normal saline and those in the betadine group (n=17) received meatal care with 10% betadine once a day for 6 days. Urine cultures were done on the 7th day for both groups to detect UTIs. Results: No difference was observed in the incidence of urinary tract infection between the two groups, regardless of patients’gender, ability to communicate or history of operation. Conclusion: The results indicated that use of saline which is cheap and does not irritate the mucous membrane is effective in preventing UTI within the first 7 days, and can be used instead of betadine for meatal care for elderly patients with indwelling urinary catheter in the ICU.
