Sustaiable development yield of groundwater in Korea has been determined according to 10 year drought frequency of groundwater recharge in the standard mid-sized watershed or relatively large area of district. Therefore, the evaluation of groundwater impact in a small watershed is hard to apply. Fot this purpose, a novel approach to estimate cell based sustainable development yield of groundwater (SDYG) is suggested and applied to Gyeongju region. Cell based groundwater recharge is computed using hydrological component analysis using the SWAT-MODFLOW which is an integrated surface water-groundwater model. To estimate the potential amount of groundwater development, the existing method which uses 10 year drought frequency rainfall multiplied by recharge coefficient is adopted. Cell based SDYGs are computed and summed for 143 sub-watersheds and administrative districts. When these SDYGs are combined with groundwater usage data, the groundwater usage rate (total usage / SDYG) shows wide local variations (7.1~108.8%) which are unseen when average rate (24%) is only evaluated. Also, it is expected that additional SDYGs in any small district could be estimated.

A demand of public using building in rural residential area changes over times. With the changes, the function and the scale of the public using building are also changed, the building is more influences on people in rural area. However, the most of facilities have been focused on the agricultural productions, and thus the facilities of health care, culture, and daylife supporting were not enough comparing to the facilities in urban area. This study surveys the facility and grasps the current status and problem of 37 rural residential area. In addition, three different revitalizing plans of public using building as a current availability and plan for use are suggested. A new community center where is expected that the public usage is increased should be managed intensively regarding an air conditioning, and waterproofing work, while an old community center and the warehouse where are expected that the public usage is decreased, but have locational advantage should be used as a rural life experience facilities and a accommodations with remodeling unless the safety matter A parking lots are considered that the availability is gradually increased and needed for public while it is difficult to get a new available site because of the ownership. Therefore, it is national decision to secure the site by removing the discarded facilities.

Developing the modern design of Hanok and providing support for the commercialization model development in recent years propelled by the New Hanok Support Strategies of the central government in conjunction with the New Hanok revitalization related projects reflecting local goverments. New Hanok revitalization, the rekindling and revaluing of human behaviors and interests in local goverments following the social and cultural changes of the past decades, has emeraged as an increasingly traditional area of concerning in New Hanok planning. In this paper we attempt to this discussion by describing recent projects in New Hanok revitalization in Jeollanam-do Province. Therefore, this study aims to examine the classification of compound knowledges based multidimensional relationship by using Self-Organizing Maps (SOM). SOM is an unsupervised learning neural network model for the analysis of high-dimensional input data. By using SOM, we were able to create a cluster map reflecting the characteristics of the New Hanok. In this case the pattern of the preference data was easily understood by visual analysis. Liking for compound knowledge deduced from this data was classified into 8 categories according to the compound knowledge properties of New Hanok. As a result, a systematic approach for analysis the characteristics of individual family and living environment of New Hanoks and 10 space usage patterns the changes in some aspects of New Hanok.

Predicting building energy use can be useful to evaluate its energy performance. This study proposed empirical approach for predicting building energy use with regression analysis. For the empirical analysis, simple regression models were developed based on the historical energy consumption data as a function of daily outside temperature, the predicting equations were derived for different operational modes and day types, then the equations were applied for predicting energy use in a building. BY selecting a real building as a case study, the feasibilities of the empirical approach for predicting building energy use were examined. The results showed that empirical approach with regression analysis was fairly reliable by demonstrating prediction accuracy of $pm10%$ compared with the actual energy consumption data. It was also verified that the prediction by regression models could be simple and fairly accurate. Thus, it is anticipated that the empirical approach will be useful and reliable tool for many purposes: retrofit savings analysis by estimating energy usage in an existing building or the diagnosis of the building operational problems with real time analysis.

The risk of a fire in a building is closely related to the usage of the building. In particular, all fires that occur in a building are not risky to safety of human life, and it is associated with the combustion area and the increase of total floor area of the building. Therefore, this study focused on safety of human life in terms of the statistics of fire with considering the aspect of growing fires and analyzed the statistical data of fire for 10 years. As for the analysis on fire, the time of occurrence by usages of buildings, frequency of occurrence and the ratio of casualties etc. were analyzed. It is expected that results of this study could be used for evaluations on a variety of parts in terms of design, construction and maintenance of buildings.

A well designed disabled home needs to consider various design principles and variables. It should consider not only physical accessibility but also psychological aspects. Previous research studies have shown that barrier-free/universal designs which were primarily focused on physical access and usage of facilities and building operations. This research paper will examine, a selection of refurbished disabled homes, introduced by the Korean Disabled People's Development Institutes in 2013. The plan samples are to be analyzed using the Visual Access and Exposure spatial analysis program coupled with supporting information extracted from consultations and feedback from experienced professional disabled home staff members. This research paper aims to propose the usage and viability of VAE Analysis in the design and planning of disabled home layouts. The purpose of this study is to specify the differences in visual spatial relationships between the plans before and after refurbishment in accordance to staff and user requirements. This will ensure a bettered environment for the users and ensuring an optimized of spatial programming and building operation and usage.
