This paper discusses the problem of determining locations for public health-care facilities and allocating patients to the public facilities with the objective of minimizing the total construction cost. The public health-care facilities have two types of facilities: public hospitals and health centers. The public hospital provides both hospital services and homecare services, while the health center provides only homecare service. We present an integer programming formulation for the problem, and develop two types of heuristics, based on priority rules and approximate mathematical formulation. Results of a series of computational experiments on a number of problem instances show that the algorithms give good solutions in a reasonable computation time.

Purpose: This study is to research how New-Hanok R&D technologies of first stage are appearing and adapted to the New-Hanok style public buildings, especially in Daycare Center in Sunchang-gun, Korea. Unlike Hanok houses, public buildings which has special needs for the public and restricted by laws and regulations need not only new system of law incentives but also new components of New-Hnaok R&D technologies used only in Hanok house. Method: For this purpose, we checked the drawings for Daycare Center in Sunchang-gun. The drawings have been changed 6 times for the purpose of adopting New-Hanok R&D technologies of first stage and actual needs for current laws and regulations for public buildings and it reveals not only the possibilities for adapting new technologies in New-Hanok but also meetings the current and public needs for public buildings. Result: The result of this study as follows. Approximately 40-50 percent of New-Hanok R&D technologies in the first stage are adapted in Daycare Center in Sunchang-gun, and this means there are limitations in adapting New-Hanok R&D which are mainly for the Korean style houses. The main reasons are the costs still remaining high and lacking in confidence for using traditional structures and materials still under verification. Some are changed and proposed in another solutions suitable for public buildings as like truss structure system in roof.

Understanding the antecedents of high public usage of national R&D facilities is a critical issue for both academics and facility managers. Previous researchrelated to general service management has identified service quality and user satisfaction as important antecedents of reuse and recommendation intention. The current paper reports findings from a survey which looked into the impact of service quality dimensions and user satisfaction on reuse and recommendation intention in the field of R&D facility public usage. Findings indicate that service quality appears to be linked to user satisfaction, and user satisfaction to be linked to reuse and recommendation intention. Findings also indicate that user satisfaction played as a mediator on the relationship between service quality and reuse/recommendation intentions in R&D facility public usage domain.

Objectives: The objective of this study was to evaluate the concentrations of airborne fungi in public transportation from autumnl 2016 to summer 2017. Methods: This study measured the concentrations of airborne fungi on six subway lines and intercity buses in Seoul. Results: The concentration of fungi in the air in public transportation was found to be lower than the standard (500 CFU/㎥) for vulnerable group facilities among public use facities. In summer, the concentration of airborne fungi was relatively higher than in autumn. The concentrations of airborne fungi in subway (252.0 CFU/㎥) and train (45.1 CFU/㎥) were high tendency during non-rush hours in summer, while intercity bus was hightendency during rush hours in summer (111.9 CFU/㎥). The major types of airborne fungi in public transportation were Cladosporium, Penicillium, and Aspergillus. Conclusions: The harmful airborne fungus were detected though they did not exceed the standard in all public transportation. As a result, further studies on the analysis of the distribution of airborne fungi by ventilation and the characterization of indoor environments are needed to propose effective management of airborne fungi in public transportation.

점차 삶의 수준이 향상됨에 따라 건강하고 여유로운 삶에 대한 니즈가 증가하고 있다. 문화에 대한 대중의 니즈를 반영하여 국내에는 여러 개의 상영관으로 구성된 멀티플렉스가 빠른 속도로 보급되고 있다. 그러나 화재발생 시 피난안전 측면에 있어 위험성을 내포하고 있다. 건물의 공간 형태에 익숙하지 않은 불특정 다수의 관객은 피난으로 인한 입장 및 퇴장 동선의 충돌로 혼잡을 겪게 되기 때문이다. 따라서 본 연구에서는 이러한 문제점을 해결하기 위하여 피난시간을 단축할 수 있는 방안을 마련하고자, 상영관별 단계적 피난을 적용하여 피난시뮬레이션을 실시하였다. 해석 결과, 전 상영관이 동시 피난하는 것보다 상영관별로 단계적인 피난하는 것이 피난시간 확보에 유리한 것으로 나타났다.

The public library and micro-library as institutions of social education have been greatly developed under the influence of the library law enacted 011 Octob~r 28,1963 and the micro-library movement begun in 1961. However, they have still yet many problems to solve in order to accomplish their purpose effectively. As compared with the staff and library materials, buildings are 1norc. than a match for the others. Although many facilities are not complete enough to serve the public, people do not make the best of the facilities in both the public libraries and micro-libraries. The cause of such a result ~vould be taken from a reason that the founders of the libraries could not concentrate their intcrest on the staff and materials, for they were bent on the establishment of external facilities of the libraries. The poorer materials and facilities are, the more effort a2d better quality of the staff are required for their best utilization. As it is the information center of the community, the management of a library should be scientific and reasmable. In addition, librarians have to do their best to serve the public with the spirit of Christianity under the more active suppxt of the government. Finally, institutions of social education in this comn~unityin cluding public libraries and micro-libraries might establish a mutual cooperative organization for more effective library service.

This study was conducted to survey and inspect the currently operating anaerobic digestion facilities for animal manure. Recently, the number of anaerobic digestion facility for livestock manure is on the rise thanks to growing interest in developing alternative energy. A anaerobic digestion system has been constructed in large scale farms or animal manure public resource center. Currently, most animal manure anaerobic digestion facilities in operation are producing biogas from the pig slurry which contains 97% water. Methane gas can be used to operate a engine generator which then produces electricity. Anaerobic digestate, a by-product of digestion, is mostly utilized as a liquid fertilizer after curing processing. Only in a few cases, it can be discharged after wastewater treatment process. The problem of anaerobic digestate treatment is the imbalance of C/N ratio. The content of N was too high to keep it into normal process.

가축분뇨 공공처리시설 유입수의 농토변경에 따른 처리효율과 비용절감 효과를 검토하기 위하여 다음을 전제조건으로 분석하였다. 첫째 유입수질을 고농도 (BOD 20,000 mg/L)에서 저농도 (BOD 1,000 mg/L 이하)로 변경한다. 둘째, 기존 시설의 개 보수를 최소화하면서 유입수 전량을 저농도로 유입시킬 경우(BIOSUF) 셋째, 시설의 개 보수 없이 유입수의 일부를 저농도로 유입시킬 경우 (액상부식법)를 검토하였다. 처리용량 확대에 있어서, BIOSUF 공법의 경우는 저류조 등 일부시설을 증설한다면, 현재의 설계 유입물량 130톤/일에서 2.3배인 300톤/일을 유입시킬 수 있을 것으로 산출되었다. 액상부식법의 경우는 설계 유입물량 210톤/일을 190톤/일로 감소시키는 대신 저농도의 유입물량을 60톤까지 확대함으로써 250톤/일 처리가 가능할 것으로 분석되었다. 톤당 처리비의 경우는, BIOSUF 공법은 유입수 농도 변경 전에는 14,674원/톤이었으나 변경 후에는 7,221원/톤으로 50.8%가 감소되었으며, 액상부식법은 당초 9,929원/톤이었으나, 변경 후에는 약 16.6%가 감소된 8,277원/톤으로 산출되어 비용절감 효과가 있는 것으로 분석되 었다. 따라서 가축분뇨 공공처리시설의 운영쵸율을 높이고 양축농가의 처리비용 경감을 위해서는 가축분뇨 (슬러리)를 농가단위에서 저농도로 처리한 후 공공처리시설로 유입하는 체계의 강구가 필요하다.
