For reference human intrusion scenarios constructed in previous study, a probabilistic safety assessment to derive the radionuclide concentration limits for the low- and intermediate- level radioactive waste disposal facility is conducted. Statistical approach by the Latin Hypercube Sampling method is introduced and new assumptions about the disposal facility system are examined and discussed. In our previous study of deterministic approach, the post construction scenarios appeared as most limiting scenario to derive the radionuclide concentration limits. Whereas, in this statistical approach, the post drilling and the post construction scenarios are mutually competing for the scenario selection according to which radionuclides are more important in safety assessment context. Introduction of new assumption shows that the post drilling scenario can play an important role as the limiting scenario instead of the post-construction scenario. When we compare the concentration limits between the previous and this study, concentrations of radionuclides such as Nb-94, Cs-137 and alpha-emitting radionuclides show elevated values than the case of the previous study. Remaining radionuclides such as Sr-90, Tc-99 I-129, Ni-59 and Ni-63 show lower values than the case of the previous study.

As multiplex available premises become more complex and diversified due to increasing social and individual demands, the evacuation safety gradually deteriorates exhibiting functional difficulties even in ordinary fires. Considering the limitations of passive evacuation systems such as evacuation stairs and corridors, an evacuation facility must be designed, installed, and maintained the way that it remains fully functional and efficient when fire breaks out. This study tries to identify the issues of evacuation facilities and devise how to improve them by investigating the evacuation facility efficiencies of multiplex available premises and conducting a survey on fire safety attitude.

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 simulation of water balance was conducted for suggested four alternative multi-layer cover design of near-surface radioactive waste disposal facility under domestic climate condition. The analysis was also conducted for the most favorable one out of four alternative cover design under conservative scenarios. Until 100 years after closure of disposal vault, the infiltration flux for the most favorable cover design was negligible even under doubling of the ambient precipitation condition. When the degradation of asphalt and geomembrane after 100 years of closure was considered, the infiltration flux significantly increased almost to the design criteria of cover system in I' Aube disposal facility. And it was found that the hydraulic conductivity of bentonite/sand as a bottom barrier should be no greater than 1$\times$10$^{-7}$ cm/sec recommended by U.S. EPA.

Cross docking is a warehouse management concept in which items delivered to a distribution facility by inbound trucks are immediately sorted out and reorganized based on customer demands and are routed and loaded into outbound trucks for delivery to customers without actually being held in inventory in the distribution facility. In this research, the design of distribution facility for cross docking systems was studied. The objective of this research is to find the minimum number of receiving docks and shipping docks, respectively, in order to meet the daily demand of the distribution center. Two solution approaches are employed in modeling and solving the problem The first approach is mathematical modeling and the second approach is a simulation. The logic developed in the simulation model is expected to apply to the real world situation.

Despite the growing interest in recreation as one of the ways to maintain physical and mental health in modern society, access to leisure facility is an issue for individuals with disabilities. This paper identifies inaccessible features to propose the ways to promote participation and usage of the leisure facilities for individuals with disabilities. A survey of individuals with disabilities is conducted to determine preferred leisure facilities depending on types of disabilities. The result of this survey is used to evaluate current condition of regulated National leisure facility and forest, which include barrier-free facilities (e.g. interconnecting zones, interior spaces, lavatories and other facilities), signage, approachable information kiosks, emergency egress, and detectable warnings. The common issues (e.g. guiding mechanism, accessible route, safety factors, and barrier-free facilities/services) in various types of recreational facilities (e.g. forest recreational center, spa and hot springs, Amusement Park, ski resort) were identified and analyzed.

The purpose of this paper is to analyze the handicapped facility in residential outside area, to found how to improve the law in analyzing the residential area and to suggest consideration factor in design phase. To concentrate the study, the objects of case study are selected carefully, also case study method is selected as well as objects. After observing the summary of objects, the checklist is made accordance with the improvement law of facility. The checklist has the general and detail factor about outdoor residential area, and the detail factor is based on the improvement law of facility and is used to examine and analyze.

This study investigated the leisure constraints and leisure life satisfaction of the institutional elderly. The respondents were 302 elderly people residing in 5 free institutionalized elderly homes in Seoul. The data were analyzed by frequency analysis, factor analysis, One-way ANOVA, Duncan's post hoc test and regression analysis using SPSS WIN 12.0 program. Exploratory factor analysis revealed that the 10 items in the proposed scale could be grouped into four factors of constraint on leisure:'physical constraint','psychological constraint','interpersonal constraint', and 'structural constraint 'There were differences in leisure constraints according to sex, age, education degree, interaction with facility colleagues, and interaction with facility staff. There were differences in leisure life satisfaction according to sex, age, having religion or not, interaction with facility colleagues, interaction with facility staff and leisure constraints. Regression analysis results indicated that the main effective factors of leisure life satisfaction were leisure constraints.

Recently cancer, AIDS, chronic sickness have increased according to the elevation of socioeconomic level and fast change of lifestyle. The number of patients receiving terminal care increased fairly because the span of life is extended by development of medicinal technology. Also necessity of hospice and palliative care was risen according to the request of terminal patients that remove pain and keep calm life by interest about quality of life. However architectural plan and type specialization of facility which can correspond team's composition and supplied nursing program are not consisting. This study researches about care environment of hospice facility plan through investigation into terminal patient's special quality. The purpose of this study is to propose fundamental datas of hospice facility for architectural plan through comparative analysis of cases of domestic and outside facilities.
