Prediction of construction cost in the planning stage that provides basic information for feasibility study, budgeting, and planning is an important factor for successful project execution. In this study, a prediction model was developed for the purpose of improving the accuracy of estimating the construction cost of Hanok in the planning stage. The cost of this model is estimated by two methods. First, the cost of wood work, which accounts for the largest portion of the total construction cost, is estimated by calculating the approximate quantity under various conditions (structure type, roof type, plane type, etc.). Second, the cost of the rest work sections except the wood work is estimated by using the unit cost model. The predictive model was verified by two case projects, and the error rate of total construction cost was -4%(case 1) and -6%(case 2). These results showed an error rate in the range that can be applied to practice in the planning stage.

This paper explores the structure of space in architecture from a viewpoint that individual unitized spaces are gathered to form the whole. To understand the spatial structure of architecture, firstly we need to understand each unitized spaces, and secondly, one must understand how the following adjacent spaces are connected to form the whole building. this gives salience to a fact that understanding the whole comprehensively. It is the most fundamental bases that must be understood and unitized when understanding the spatial structure of an existing building and designing a new one. It is necessary to hypostatize space as an abstract notion. In regards to this space examines the logical flow of structure within actual space. Hypostasieren process includes the process of shaping space and the shape information. In this process we need to refer to the properties of space and the morphological characteristics of physical elements. The segment of the unitized space is the realization process of the basic space. This study aims to provide a theoretical basis for analysis and design of spatial structure by comparing several representative methods of segmenting unitized space.

Health care services in a residential area would accelerate the aging in place. In addition, these changes would play a key role in terms of reducing healthcare costs and leading a healthy lifestyle. The purpose of this study draws the design methodology of community facilities and each dwelling with healthcare services in apartment complex, which the elderly people will enjoy a better health status. This paper presents the result focused on the welfare building in Gayang 7th apartment complex. The intention to receive healthcare services was investigated by occupants. Moreover, design requirements were drawn through in-depth interviews and the state observation to use the service. In the complex, stronger intention to serve the u-Healthcare services was shown to the pre elderly group than the elderly. Both of them had a problem to use and keep the health equipment due to the fact there is not enough space in the unit. Reporting the observation results, the upright-posture furniture attaching the healthcare equipment and the equipment storage should be prepared in the unit. In the public space, the program for these healthcare services can be divided into three parts, i.e. the health status measurement, the healthcare, and the service connected to the surrounding facilities. The health status measurement can be the basic to the health services and its function should be gradually extended. In the complex, the hybrid type with various functions could be applied owing to a new building for welfare; moreover, semi-independent user should be able to receive the home healthcare service.

This study is aimed to provide a guide for PC use space in apartment. To achieve this, a design about PC use space which was considered adequate location, area, form was suggested. As methods of the study, survey research method and case study. The survey was taken by five hundred-eighty-nine people who used PCs in apartment from May 2005 to July 2005 in JeJu Special Self-governing Province for an analysis of data. The results of the survey were showed PC use space situation and furnitures layout patterns. The case was classified by unit plans of size, and it showed design example of PC use space. In types of $61{\sim}69$ square meters ($m^2$), PC use space was located in dead-space in the residence with minimum scale, because of $61{\sim}69$ square meters types are smaller than the other types. In types $100{\sim}129$ square meters, PC use space which was divided with a partition panel was located in the livingroom expanding the room space to the balcony. In types of 130 square meters, PC use space was located in the room of sons or daughters which was arranged with other furniture. The adequate area of PC use space is $1.4{\sim}2.2$ square meters, and it should take into account furniture size and human active sphere. And PC use space of form should consider traffic line, personal space and privacy. Besides it is required of ergonomic design in chair, table in its scale. And it is necessary development of systematic furniture for PC use space.

The purpose of this paper is to investigate the planning characteristics of certain cases of elderly welfare housing (hitherto EWH), and analyze any problems by comparing this against the actual needs of potential residents. To this end, 38 distinct housing plans from twelve EWH built after 2005 were examined, and a survey on housing needs was taken by 198 people between 48 and 62 years of age. The results are as follows: Firstly, the most common size found among the 10 cases was 42-66 $m^2$, however larger sizes are becoming more frequent. The most popular response on the survey was one favoring smaller housing options. Secondly, the most common floor plan examined consisted of 1 bedroom + LDK and 2 bedroom + LDK. Likewise, the survey reflected that 1 or 2 bedroom housing was preferred. Thirdly, a floor plan composed of a smaller bedroom and LDK is commonly found in smaller floor plans of EWH. The survey reflected potential residents preferred this same style of floor plan, with a smaller bedroom and LDK set up. However, lower-income participants preferred a single, larger bedroom which also can serve as a living space, to go along with a kitchen/dining room (DK). Fourthly, 2 bedroom housing typically included a single bathroom, however the survey indicated that participants preferred a second bathroom to go along with a second bedroom. Consequently, the planning of elderly welfare housing is to a large extent meeting the demands of its potential residents, however house size and the planning of bathrooms have yet to meet these demands, especially with potential lower-income residents when it comes to housing size and space composition.

Wetland conservation plan has been established to protect ecologically important wetlands based on vegetation integrity, spatial distribution of endangered species, but recently more demands are concentrated on the landscape ecological approaches such as topological relationship, neighboring area, spatial arrangements between wetlands at the broad scale. Landscape ecological analysis and graph theory are conducted to identify spatial characteristics related to core nodes and weak links of wetland networks in Nakdong basin. Regular planar model, which is selected for wetland networks, is applied in the Nakdong basin. The analysis indicates that 5 regional groups and 4 core wetlands are extracted with 15km threshold distance. The IIC and PC values based on the binary and probability models suggest that the wetland group C composed of main stream of Nakdong river and Geumho river is the most important area for wetland network. Wetland conservation plan, restoration projected of damaged and weak links between wetlands should be proposed through evaluating the node, links, and networks from wetlands at the local to the regional scale in Nakdong basin.

The purpose of this study was to analyze the type of extended-balcony floor plan which has been reflected as a various forms after making amendment to the apartment extended-balcony legislation on December 2005 and to understand the design tendency of housing unit plan and the characteristic of living space planning by the type of size(pyeong) and extension. The objects of analysis and the plans are 333 example(235 of $84m^2$, 98 of $59m^2$) from the LH corporation competition. The design tendency of balcony space after extension is as follows; First, a type of extension for simple area to increase the area of room adjacent to balcony through balcony extension. Second, a type of functional reinforcement for private room to separate the mixed function followed by strengthening the individual function of the private room. Third, a type of ${\alpha}$-room to play new functions as hobby room, study room, soho-type room with working from home by extending balcony. Fourth, a integrated type to increase flexible efficiency of bed room, living room and kitchen by integrating extended-balcony from the flexible plan. Along with the evaluation of living style through user's environment-behavior research and the counterplan for evacuation space, indoor thermal environment and space for fulfilling the original function of balcony should be proposed in the future study.

The purpose of this study is to understand various styles of Korean house living, up to the present, to identify apartment living as the main house living, and plan and propose the interior unit spaces for apartment house based on the analysis on living space. A survey study was conducted to deduce the traditional major life style and its changes along with favorable housing spaces. In conclusion, this study proposed the unit space planning requirements that satisfies the conceptual and interior elements for habitant's characteristics and preference according to major life style as follow; 1) As the Ahn-bang(master bed room) has been changed from traditional space concept, it is mainly used as private space for husband and wife, and its utilized period is mostly at night time, the back-arrangement of the Ahn-bang should be considered. 2) As the living room is central space in the apartment housing and has complex functions which is utilized as space for family gathering and guest reception similar to the Ahn-bang of the traditional house, it should secure more space and it is desirable to arrange the space as open type by combining the pathway area. 3) As for the kitchen/dining room, the kitchen should be isolated from external attraction and the space for storing and preparing traditional foods should also considered, and the dining room should be arranged as open type. This study also suggests that since the apartment housing must be an integrated environment for habitants which satisfy behavioral, physical and mental elements simultaneously, the unit housing space should be constantly analyzed in various ways to produce a housing space which meet both their changing major life style and the temporal environment.
