예방정비기준은 기기의 높은 신뢰성을 유지하기 위해 정비방법을 문서화한 것으로 기기별 최적화된 예방정비 항목과 주기를 명시하고 기기의 성능저하 메커니즘을 설명하는 지침서이다. 기존의 기기 또는 설비에 대한 정비전략은 상태감시 정비보다는 일정한 주기가 되면 정비를 수행하는 주기정비가 주된 전략이었다. 본 논문은 원전 정지형 여자기에 대하여 기존의 주기정비 형태가 아닌 상태기반 정비 기법을 강화하고 정비 프로그램을 표준화하여 최적화된 정비전략을 구축하기 위한 예방정비 기준을 개발한 내용으로 기기 신뢰성, 발전소 이용률을 향상시킬 수 있는 기반이 될 것으로 판단된다.

So far we have investigate and analyzed the actual conditions of building maintenance in Korea and compared the building maintenance laws and systems between Korea and other countries. Now, based on the results from such comparison and analysis, this study proposes the following ideas for improvement: 1) As we can learn from domestic and foreign case studies, in the existing built-up areas becoming obsolete, many building owners remodel their buildings illegally in reaction to current economic and social changes. Therefore, for efficient maintenance of buildings, it is required to improve building maintenance systems by formulating information about inspection items, inspectors, supervisors, inspection costs and intervals of reporting results, depending on how large the buildings are and what they are used for. 2) In addition, to ensure the success of a building maintenance system, it is necessary to keep and manage a history of building maintenance thoroughly and introduce a certification program which gives an appropriate grade to maintenance performance and commits the government to expand their public roles and supporting policies, as widely used in some foreign countries. Further, in keep the building maintenance system secure, there should be a nationwide consensus as well as a favorable evaluation from building owners and manager, and all related people.

지금까지의 정보시스템 유지보수비 산정은 발주자 중심으로 이루어져 업무량에 비해 적은 비용으로 인한 공급자의 원가부담 문제점을 해결하지 못하고 있다. 본 연구는 공급자 중심에서 정보시스템 유지보수 비용을 산정하기 위한 기반연구로서 유지보수의 비용 항목을 도출하고 발주자와 공급자의 유지보수 비용의 격차를 조정하기 위한 조정계수를 제안한다. 유지보수의 비용항목을 도출하기 위하여 기존의 유지보수 활동에 대한 비용요인 기반연구에 유지보수 공급자의 활동들 추가하여 고정비와 변동비로 구분하고 분류한다. 발주자와 공급자의 유지보수 비용의 격차를 조정하기 위하여, 발주자 중심의 유지보수 비용 산정 시 포함되지 않은 자동화 도구에 의해 생성된 코드, 유틸리티, 컴포넌트 등과 같은 조정요인들을 찾아내고 K기업의 3년간 유지보수 수행 데이터를 검토 분석하여 조정계수 요인에 대한 격차가 K기업의 경우 13%정도가 됨을 확인하였다.

This study was attempted in order to look into 'Assist work' as to Implant system which dental hygienists perform in a clinical field. Subjects of this research were 362 dental hygienists who work at general hospital, University hospital, dental hospital, and dental clinics located in Seoul, Kyeong-gi, In-chon, and Jeon-buk area. As to research tool, we produced questionnaire which was comprised of the total 25 items regarding 3 of general features (age, career of dental hygienist, and personality), 6 of implant system assist work, 3 of Informed consent before surgery, 6 of preoperative preparation and maintenance related business, and 7 items related to postoperative maintenance. By using SPSS program, collected data was analyzed. Results of analysis in this study were as follow; 1. As to implant related education, dental hygienists' experience of education was high as 77.7%, and the people who is needed more education was 86.3%. Consequently, dental hygienists' concern about the implant related education was very high. 2. It was observed that most of informed consent making approvement by announcement to the surgical operation was made by dental hygienist before implant as 95%. 3. Over 80% of dental hygienists performed acquisition of cleanliness technology, motivation, back up articles preparation, treatment area arrangement, and etc. which we can check by preoperative maintenance items. In particular, response about the motivation was very high as more than 90%. 4. When performing an operation, in the case of disinfecting finger was low for 53.9% and the method was mainly washing with drug solution, and gown sterilization was performed only in 52.2%. Therefore education regarding disinfection was urgently needed. 5. Significance of education could be known that answers of hygienists experienced education appeared highly in items of maintenance method and there was statistically significant difference(p<0.05). 6. In case that assist work were 21cases or greater, agitation measurement was the most many performed in 68.9% and difference was showed up significantly(p<0.001). 7. Evaluation about periodontal tissue was high in dental hygienists who had experienced education and also there was statistically significant difference. In conclusion, assist work of dental hygienists was very comprehensive when implant surgery was performed, and all of items excluding hand disinfection or gown disinfection were highly showed up in most of hygienists. However, since there is the limit that we didn't investigate the quality of performing contents. It is considered that further study regarding the content has to be progressed for supporting this result in the future.

국방부는 노후 된 병영생활관 현대화 개선을 추진하여 고시된 75개 사업 중 60개 사업이 운영 중에 있다. 따라서 과거에는 데이터 조사 분석이 어려움이 많았으나 현재는 민간 운영사로부터 정보를 파악하고 분석할 수가 있다. 본 연구에서는 시설물의 사용성을 높이기 위하여 병영시설물의 3~5년 수선유지비의 예산과 사용 데이터를 조사 및 분석하여 문제점을 도출하여 수선유지비에 대하여 합리적인 대안을 제시하는 목적으로 하였다. 이에 맞게 이론적 고찰 및 선행 연구, 수선유지비에 대한 법적인 근거, 국방부 병영시설 BTL사업의 수선유지비 예측 비용과 사용 데이터를 분석하였다. 도출된 문제점으로는 첫째는 소모품, 없는 항목, 누락 항목에 대하여 예산을 추가로 확보하는 개선방안을 제시 하였다. 둘째는 평균으로 분할하는 지급에 대하여서는 3~5년 운영기간에는 축소하여 지급하는 개선방안과 장기수선계획 수립기준으로는 예산이 없거나 작게 지급되어 3~5년 운영기간에는 예산을 추가 또는 보완하여 지급하는 개선방안을 제시하였다. 향후 병영시설의 운영기간과 실적 데이터가 추가로 확보가 가능한 시점에 수선유지비 효율적 연구는 보완되어야 한다. 본 연구는 향후 국방부 병영시설 건설에 대하여 사업비를 합리적으로 유도하는데 기여할 수 있을 것이다.

Large hospitals such as medical centers provide not only medical services, but also carry the responsibilities for emergency refuges, medical researches and education. The function of large hospitals is as important as other infrastructure systems such as highways, bridges, and utilities. When disasters occur, the hospitals have to provide emergency medical services for victims and support the patient's needs of health. In order to keep a smooth operation of hospitals, the maintenance management of hospital buildings should be carefully investigated. However, there are few researches focused on maintenance management issues of hospital buildings. This paper investigated the National Taiwan University Hospital (NTUH) and established a maintenance cost database. The NTUH is the best-known and most high-renowned medical center in Taiwan in which more than 4,000 employees serving approximately 2,000 in-patients and 7,000 out-patients daily. The data were collected from the NTUH which consisted of 16,228 maintenance records in the past ten years. This paper analyzed these data to obtain various characteristics of maintenance records, and revealed the key items of maintenance cost for large hospital buildings, which can provide the facility manager of hospital buildings to execute a proper maintenance policy for hospital buildings.

Many countries have carried out various policies about sustainable building to protect the earth against the global warming and environmental pollution. Korea government has also executed the Green Building Certification System. In order to keep the performances of certificated buildings sustainable, the effective building maintenance is quite necessary. Meanwhile, the foreign green building certification systems have considered the building maintenance as one of the most important items to keep the building performance effective. However, Green Building Certification Criteria(GBCC) of Korea has not had the sufficient criteria for the maintenance of green building. Therefore, The purpose of this study is to find direction for the improvement of management categories of Korea Green Building Certification Criteria. For this aim, GBCC was compared with the foreign certification systems such as LEED, BREEAM and CASBEE.
