Background: The types and effects of hazardous pollutants in indoor air may vary depending on the characteristics of the sources and pollutants caused by physical and chemical properties of buildings, the influence of outdoor air, and the exposure and use characteristics of residents. Objectives: This study was conducted to provide basic data on the establish of indoor air quality management for different classes of public-use facilities by presenting the characteristics of concentration distribution of hazardous pollutants by different public-use facilities and the status of the excess proportion of exceeding standards. Methods: This study analyzed self-measurement data from public-use facilities taken from 2017 to 2019 A total of 133,525 facilities were surveyed. A total of 10 types of pollutants that have maintenance and recommended standards stipulated in the Indoor Air Quality Control Act from the Ministry of Environment were investigated. The excess proportion and the substances exceeding the criteria for each type of public-use facilities for these pollutants were investigated. Results: As a result of the analysis of the proportion of exceeding the standard for each type of public-use facility, the facilities with the highest excess proportion of the standards for each hazardous pollutant were: PM₁₀ in railway stations (8.93%), PM_2.5 in daycare centers (7.36%), CO₂ in bus terminals (2.37%), HCHO in postpartum care centers (4.11%), total airborne bacteria in daycare centers (0.69%), CO in museums (0.1%), NO₂ in postpartum care centers (1.15%), Rn in museums (0.78%), total volatile organic compounds in postpartum care centers (7.20%) and mold in daycare centers (1.44%). Conclusions: Although uncertainty may arise because this study is a result of self-measurement, it is considered that this study has significance for providing basic data on the establishment in the future of indoor air quality management measures customized for each type of public-use facility.

Objectives: This study aims to assess the concentrations of ammonia and hydrogen sulfide according to task unit area at swine farms. Methods: A total of six swine farms were selected for this study. Ammonia and hydrogen sulfide were monitored using a real-time multi-gas monitor which could sample the gases simultaneously. The sampling was done in the pig building, manure storage facility and composting facility of each farm. Results: The concentration of ammonia in the pig buildings(GM 22.6 ppm, GSD 2.3) was significantly higher(p<0.0001) than in the manure storage facilities(GM 10.4 ppm, GSD 2.7) and composting facilities(GM 8.6 ppm, GSD 2.8). The concentration of hydrogen sulfide in the manure storage facilities(GM 9.8 ppm, GSD 3.2) was higher(p<0.0001) than in the pig buildings(GM 2.3 ppm, GSD 2.3) and composting facilities(GM 1.9 ppm, GSD 2.5). In particular, the levels of hydrogen sulfide in the confined manure storage facilities were higher than those in open-type facilities and the peak concentration(98 ppm) in the confined facilities was approximate to 100 ppm, at the value of Immediately Dangerous to Life or Health(IDLH). Conclusions: Suffocation accidents caused by hazardous gases at a swine farm have occurred annually. Real-time monitoring of the hazards should be done in order to protect farm workers and livestock from the sudden accidents.

주도적 주거유형이 공동주택단지로 자리잡아가며 현대사회에서 주거환경에 따른 커뮤니티의 문제가 중요한 이슈로 자리 잡고 있다. 그리고 이는 전통적 공동체의 붕괴와 이로 인한 사회적 문제의 양산으로 나타나기 시작한지 오래이다. 공동주택단지내 커뮤니티의 활성화를 위하여 다양한 논의가 지속되어 왔으며, 본 연구에서는 이를 위해 서울, 수도권, 지방대도시의 공동주택단지를 조사 분석하여 커뮤니티 시설의 모델을 제안하고자 하는 설계형 연구로서 도출한 결론은 다음과 같다. 공동주택 관련 법규에서 규정하고 있는 커뮤니티 시설 기준에 견주어 프로그램의 다양성에 있어서는 한계를 갖고 있는 것을 확인할 수 있다. 이는 점차 여가의 질의 향상을 기대하는 거주민의 만족도를 충족시키는데 한계로 나타나고 있으며, 물리적인 시설환경을 중심으로 기준화하고 있는 시설기준은 점차 질에 있어서의 요구가 증대하고 있는 가주민의 만족도를 높이는데 한계가 있으며, 이를 위해서는 시설기준의 다양성을 고려하는 접근이 선행되어야 할 것이다. 공동주택의 외부공간 이용성이 증대되고 있는 오늘날 커뮤니티시설의 지하공간을 활용하며, 건축적 요소를 통해 환경성을 확보하는 방안이 고려될 수 있으며, 이는 커뮤니티시설의 내·외부 공간의 이용성을 높이는데 장점을 갖는다.

The significance of hydro-power plant is increasing in its public roles such as flood control and water supply as well as electric power production. Even if high level of reliability in facility operation is required, no specific reliability research has been made. This specifically stems from the lack of technology and research investments. The eventual goal of this study is to secure a methodology for reliability analysis of hydro-power plant so that an appropriate decision for operation and investment can be made. Specific effort was put to develop a reliability model for water supply system within hydro-power plant. For this study, we briefly examined the overview of the hydro-power plant including the electric power generation facility system. We then discussed the facility reliability analysis methodology for hydro-power plant. Based on rigorous examination of the water supply system and components roles, we drew major failure modes for each component and examined their effects.

In this paper, a shared model of systematic urban facility construction planning system is proposed. As the scope of construction on urban facilities has expanded, the construction process may occur simultaneously in the same location and short period of time by the different public agencies. This kind of construction duplications may cause the inefficiency of construction time and cost. In order to improve this, we studied the sharing method of the construction information which are produced by the different construction agencies. And also studied the method of find out the duplicate constructions occurring in the same place and short period of time. And Then we suggest a system that can rearrange the order of urban facility construction.

Nowadays, public rental apartments' community facilities emphasize only their quantity aspect without considering residents' characteristics, leading their installation regulations to be based on only the number of households, which is problematic. As a result, in many cases, residents, after moving in, alter the facility usage or remodel the facilities for their use. Hereby, this study conducted focus group interviews with public rental apartments' residents as to find out space conditions of and improvement demands for the community facilities. Two public rental apartment complexes in Seoul and Gyeongi-do which were built after 2007 were selected for this study. As for the survey method, workshop panel was employed. Four people in each age class of infants, children, adolescents, adults, and seniors were formed into one group, and a total of 40 people in 10 groups were surveyed. The survey was continuously conducted from February to March in 2009. The study findings can be summarized as follows. 1) Among community facilities, there were more satisfactory outdoor facilities than satisfactory indoor facilities. Residents expressed satisfaction with the facilities linked with natural environment. The causes of unsatisfactory facilities were mostly poor management. 2) The facilities demanded by the residents included ones relevant to study, exercise, and hobbies. As public rental apartments are resided mostly by low-income families, study and hobby activities bring them cost problems. Therefore, it is needed that the apartment complexes support diverse such activities 3) As for facilities demanded for usage alteration, a residents' meeting room accounted for the most popular opinions. As it was used only once a week, its usage was very low. It should be opened to the residents and allowed to be used in various ways. 4) As for demands of changing spatial characteristics, outdoor exercise facilities accounted for the most opinions. Although they were installed in most cases, they were damaged and poorly managed, therefore being in need of improvement in operation and management. In order to maximally utilize public rental apartments' community facilities, facility planning in consideration of various age groups from residents' viewpoint and sustainable systematic management are required.

The purpose of this study is to figure out the trends of the community facilities patterns in the designated apartments through the method of analyzing a case of a community housing yet to be open to its tenants. The thesis is based on document research and analysis of apartments categorized into five different groupings all in a status of being a prospective dwelling. The conclusion of the case study results as follows. Firstly, the distribution of a plan is either centrifugal or widespread. Secondly, the elevation plan contains its facilities in the basements or low-rise floors. Thirdly, sports facilities such as an indoor driving range, a fitness club and a GX-room and a open square on the outer space were unifiably common to all five groupings. In conclusion, in light of the facility patterns shown in the five extracted groupings of apartments, it seems that it will be difficult for all residents to benefit from the public facilities because the facilities are perceived as being limited to only a specific tower which hampers the improvement of the quality of life of the rest of the tenants and dampens an active social gatherings. Therefore, the public facilities must be planned and constructed to meet the satisfaction of the residents in whole, in place of being a commercially lucrative space.
