The purpose of this study was to analyze spatial composition of elderly skilled nursing facility and to provide basic information for setting up the detail facility architectural guidelines. The results of the study were following: the residential spaces of the facilities in this study were more or less overcrowded since their capacity were more than 5 elderly residents. The dimensions of some residential spaces did not even come up to the standard of elderly welfare law in force. On the other hand, the facilities had a tendency to use a space with multiple purposes or to allocate a space but to leave it with no use. Moreover comparing with the 1st floor, which was mainly for the staffs and had enough space to spare, the upper floor which was for the elderly residents, was crowded with nursing staffs and elderly residents and had densely closed residential and public spaces. For the problem solving, law and regulation modification is needed according to the case study about the usage and using frequency of each facility space. And the crowded area for the elderly residents could be enlarged through the reduction(or combination) of the rarely used spaces and moving a few residential spaces into the 1st floor.

This study starts off by stating that the lack of awareness in the importance of reasonable and systematized layout in management facility is essentially working against building a quality public library. And that there is a merit in studying the spatial elements, its density, amount of needed space, and the likes to efficiently deal with present workings of the library which are becoming more dynamic and complicated. This paper seeks to embark on this study and also to provide a foundational data for research on management facility of the public library. The paper bases its research on 10 public libraries which are located in Seoul City and in Gyeonggi province, and are built after the year 2000. The paper focuses on the spatial distribution by section and allotment of management facility space in the library. Consequently, to find solutions or to suggest improvements on problems encountered, the paper introduces Japan's cases (4 recently-built public libraries) as a foreign case study. With foregoing domestic and foreign library case analyses, and the survey results of managerial staffs' demands, the paper seeks to provide basic data about management facility space and its floorplan of the public library. The paper bases its research on pubic libraries' management facilities, and expects to contribute to the efficient building of the public library in the future.

The objective of correction is to let criminals receive education, be reformed and get vocational training during prison term by being separated from society and live as sound citizens after being released from prison. The facilities that execute such mission are referred to as corrective institution, and in Korea, some 47,000 persons are accommodated at 50 locations. Corrective facilities are facilities existing to separate and accommodate criminals safely, and return them to society after eliminating criminal nature from the convicts during the accommodation period. But corrective facilities in Korea representing the characteristics of corrective facilities vividly focusing on security. Therefore, while present pursuit of corrective facilities is to seek for reformation of criminals rather than separation of them from society, existing prison buildings are not appropriate facilitated at the moment. This study has the purpose to planning of indoor environment of corrective facility ward building as healing environment. Specifically, this study is contributing to propose a model of criminals healing environment equivalent to hospital facility to raise the effect of healing the criminal nature of criminals and cut the period of restoring them by applying healing environment elements and return the criminals to the society as successfully reformed social member.

A peak cooling and heating load($kW/m^2$) and annual energy($kWh/m^2{\cdot}yr$) have been simulated for a special greenhouse located near Seoul. The special facility was designed for living plant and butterfly with many visitors. The design conditions for the facility have been discussed with the designer and simulated with the weather and building conditions. The load and energy simulation was done by TRNSYS 15 based on IPMVP 4.4.2.'s simulation requirement. The results have been shown in terms of area($kW/m^2$) and volume load and energy index($kWh/m^2{\cdot}yr$). Considering the higher height of the facility, The results came out reasonably comparing the index of a typical commercial building signed as $462kWh/m^2{\cdot}yr$.

The lifestyle of customers visiting nail shops is categorized into four such as the types of 'pursuit of fashion', 'pursuit of brand', 'conservative frugality', 'premeditated pursuit'. Subjects are divided into 3 groups such as a 'pragmatist group', an 'achievement-oriented group' and a 'brand-oriented group'. Customers satisfaction level was measured in the subcategories of a 'personal service', a 'technical service', a 'facility service' and an 'after-sales service'. Their satisfaction levels depending on the types of customers' lifestyle have meaningful differences in a 'technical' and an 'after-sales' service. The 'pragmatist group' shows the highest mark in a 'personal service' and an 'achievement-oriented', it prefers the 'personal' and 'facility service' evenly. The 'brand-oriented' group shows high concern in the 'technical service'. Concludingly, the types of customers' lifestyle which influence their revisiting of the nail shop have deep relation to customers' satisfaction level in the 'personal', 'technical', 'facility', and 'after-sales service' of nail shops. Especially the 'facility service' is highly influential in customer's revisiting.

The HANARO, a multi-purpose research reactor of 30 MWth open-tank-in-pool type, has been under normal operation since its initial criticality in February, 1995. Many experiments should be safely performed to activate the utilization of the HANARO. HANARO flow simulation facility is being developed for the endurance test of reactivity control units for extended life time and the verification of structural integrity of those experimental equipments prior to loading in the HANARO. This facility is composed of three major parts; a half-core structure assembly, a flow circulation system and a support system. The flow circulation system is composed of a circulation pump, a core flow piping, a core bypass flow piping and instruments. The system is to be filled with de-mineralized water and the flow should be met the design requirements to simulate a similar flow characteristics in the core channel of the half-core structure assembly to the HANARO. This paper, therefore, presents an analytical analysis to study the flow behavior of the system. Computational flow analysis has been performed for the verification of system pressure variation through the three-dimensional analysis program with the standard $k-{\epsilon}$ turbulence model and for the verification of the structural piping integrity through the finite element method. According to the analysis results, it could be said that the design requirements and the structural piping integrity of the flow circulation system are satisfied.
