Purpose: This study is for the facility eligibility and improvement evaluation analysis for the patient care environment of 7 facilities which has national inpatient isolation units. Methods: For the evaluation, first of all, the patient care environment of national inpatient isolation units are scrutinized by the checklist which is used on from 2014 with the 4 fields of criteria : architectural planning and layout, general requirement and condition for operating the negative pressured isolated patient room, HVAC system, and waste water discharging system. Finally, the evaluation results are compared with that of 2014. Results: The result shows that the average value of facility eligibility is 89.3 percent and which is 8.9 percent higher than the value before the MERS occurred. Implications: It is clear that facility remodeling of 7 institutions is being performed continuously, and the result of facility eligibility evaluation is reflected on design of a new 21 national inpatient isolation units those are going to be constructed from 2016. Therefore, it is expected that this study is used as a practical reference to establish the criteria of patient care environment management and safety management for both infectious disease outbreak and general service condition.

In Korea, respect for the aged and filial devotion is treated as basic ethics for human life, and family takes care of the aged person mainly. Nowadays, family support on the aged person is prioritized than the others. However, number of aged person is growing, and family, which is used to protect the aged, becomes nuclear through industrialization. In addition, social advancement of female induces weakened supporting function of family, and all these issues generate the problem of protection for the aged as significant social problems. Author conducted oral inspection and questionnaire for the aged in some welfare facilities in Gyeongnam location from December 2005 to February 2006 to improve quality of life and oral hygiene of the aged. Through gathered data, the actual condition of oral hygiene management on the aged person in welfare facility was evaluated as fundamental data for project development on oral hygiene of aged person. Through the analysis of inspected data, the following conclusions are derived. 1. Management status of oral hygiene is mostly not good, and toothbrushing per day is 'one time' for the most cases. 2. In free-of-charge facility, monthly allowance is 'under 50 thousand won' for the most cases. 3. Time for visiting oral treatment facility is on 'when toothache is occurred' for the most cases. For treatment content, 'prosthetic dentistry' takes 36.8% in charged facility, and 'tooth extraction' is 27.0% for free-of-charge facility. 4. Average DMFT index of the aged in charged facility is 16.81, and free-of-charge facility is 21.71. 5. Average number of functional teeth in charged facility is 15.22, and free-of-charge facility shows 7.29. 6. Average number of remained teeth in charged facility is 15.71, and the umbe in free-of-charge facility is 9.04. 7. Average number of extractable teeth in charged facility is 0.48, and for free-of-charge facility, the number goes up to 1.70.

This study was conducted by survey and inspection of stair passage leading lights in shopping buildings which are more than 5 stories and have an underground parking lot located at Pyeongtaek-si and Seongnam-si. Number of shopping building for this study is 30 and of stair passage leading light inspected by two lights in each shopping building is 60. The result of this study is that the type of installed leading lights is LED(77%), and 60% of leading lights has problem such as no cleaning, scratch and discoloration, etc. The height of installed leading lights meets the fire law which is less than 1m from the floor. Visible condition of leading lights is good except some leading lights which have a little visible problem due to banner advertisement. 37% of standby power has flickered and went out. 93% of total leading lights meets the fire law which is more than 1lux from 0.5m distance, but cold cathode fluorescent lamps(CCFLs) have the problem which not meets proper brightness level based on fire law. In additional measurement result, zero lux of leading lights is 32%(from 1m distance), 68%(from 1.5m distance) and 98%(from 2m distance). Leading light is very important facility because it is eyes and guide when emergency. Therefore, proper fire facility operating function inspection and total detailed inspection are important to keep the good condition of leading light except simple visual check, and also improvement in law system of type approval, fire construction inspection and illumination level will be needed.

An university dorm has significant implications in terms of providing residential, living, and learning spaces. With its supportive function, a dorm enables each university to provide higher level of education. The operation & maintenance(O&M) condition of the dorm has a decisive effect on the students' satisfaction. Accordingly, high levels of O&M services should be performed for students. However, Korean dorms are being operated and maintained by their own O&M guidelines without the consideration of spatial characteristics of dorm facilities and the comprehensive and systematic understanding on effective O&M processes. Given the fact that dorm facility can be a crucial factor in determining the entire quality of university and its O&M condition is closely related to the satisfaction of students, it is imperative that we need to pay more attention to the O&M condition and services. Therefore, the main objective of this research is to improve dorm students' satisfaction levels by applying different O&M method, preventive maintenance rather than reactive maintenance which has been performed so far. In ordering for doing it, 'Facility Management(FM) Standard' from KS, 'Facility Performance Indicator(FPI)' from APPA: Leadership in educational facilities and 'Building O&M Inspection Manual' from Korean Ministry of Land, Infrastructure and Transport were analyzed to come up with 15 significant O&M factors. After extracting O&M factors, the survey was conducted to determine importance rate and performance rate of each O&M factor. Using the Important-Performance Analysis(IPA), the priority of 15 O&M factors was established. The result of this research will be helpful for the efficient dorm facility O&M services and for facility managers to appropriately allocate the limited resources and human power.

Condition-based maintenance (CBM) has been used as a useful concept for optimizing maintenance plan and decreasing maintenance cost in several kinds of plant sites. This study introduced an example that developed an integrated management system for maintenance parameters and hydraulic turbine of hydro-power plant in order to improve its maintenance system as applying CBM techinique. The integrated management system consists of three parts. One is a hardware part including PDA inspection system and several kind of precision measuring instruments. Another is a vibration monitoring system on hydraulic turbine. The other is a software part that takes charge of making hierarchy tree of maintenance parameters and their inspection route, managing accumulated database, assessing health condition of components, and supporting interface with other enterprise management system. The system has been installed at Chuncheon Hydro-power plant for test and demonstration. It is expected that the system can contribute database construction for diagnostics and prognostics on facility health condition and systematic accumulation of know-how on operation and maintenance of plant.

시설물의 고령화로 인한 유지관리 비용을 줄이고 안전성을 확보하기 위해서는 시설물 유지관리 데이터를 활용하여 향후 시설물의 상태를 예측하고 이를 유지관리 의사결정에 활용하는 것이 중요하다. 이를 위해 본 연구는 XGBoost를 활용하여 다양한 유지관리 정보로부터 향후 시설물의 부재 상태를 추정하는 방법론을 제안함을 목표로 한다. 방법론의 유효성을 검증하기 위해 교량시설물을 대상으로 샘플 데이터를 구축하고, 차기 정밀안전점검 및 정밀안전진단 시 부재 상태등급 예측모델을 개발 및 평가했다. 예측모델의 성능 평가 결과, 주요 부재(바닥판, 주형, 교대/교각) 상태등급을 예측하는 데 준수한 성능을 보였다(평균 F1 score 0.869). 또한 개발된 예측모델의 실무적 활용 가능성을 실증하기 위해 FMS 유지관리 데이터 관리 기능과 주요부재 상태등급 예측 기능을 제공하는 테스트베드를 구축했다. 이를 통해 본 연구에서 구축한 샘플 데이터와 예측모델을 활용하여 시설물 관리자에게 유지관리 의사결정에 필요한 시설물 정보 및 시설물 상태 예측정보를 제공할 수 있음을 확인할 수 있었다. 향후에는 추가적으로 데이터를 수집하고 다량의 데이터가 축적된 경우 좋은 성능을 보인다고 알려진 딥러닝 알고리즘을 활용함으로써 예측 성능을 높일 수 있다. 또한 제안된 방법론을 터널, 항만 등 다양한 시설물에 적용하여 상태등급 예측모델을 개발할 수 있다.

변전소, 댐, 철도 등과 같은 공공시설들의 출입은 매우 엄격하제 관리되어 있으며 최근에는 IT기술의 발전과 정부의 비용절감정책으로 무인감시설비가 도입되어 운영되고 있다. 그러나 무인감시설비에 고장이 발생되면 감시 공백과 침입자에 의한 정보유출과 시설파손 등의 피해가 발생할 수 있다. 또한 감시설비의 점검을 위해서는 관리자의 주기적 방문점검이 필요하며 이로 인해 추가적인 관리비용이 발생되는 문제점을 갖고 있다. 이를 해결하기 위해 본 논문에서는 무인감시설비의 동작 상태를 실시간 점검하여 문제 발생 시 자동복구를 시도하고 관리자에게 이를 통보하는 시스템을 설계하였다. 설계된 시스템은 영상, 음향, 조명 상태 등의 정보를 수신하고 판단하는 NVR과 무인감시설비의 상태를 감지하고 복구를 시도하는 제어장치로 구성되어 있다. 본 논문에서 제안된 시스템을 이용하여 무인감시설비의 고장으로 인한 감시공백 최소화와 점검비용의 감소로 인한 경제성 향상에 기여할 것으로 기대된다.
