Recently, the demand for three-dimensional spatial information has continuously been increasing, and especially, studies of indoor/outdoor spatial information or data construction have actively been conducted. However, utilization of spatial information does not universally spread to the private sector, but it is mostly used for the government offices. Thus, this study deals with the creation of three-dimensional right objects and the technique of expression to further vitalize the private sector, three-dimensional right objects, aiming to create and express three-dimensional right spaces in a particular system or open platform more conveniently. Unlike a plane text or apartment building used in existing maps was iconified and displayed simply, this study proposes a method of extracting data from the outer border of the building by the relevant level based on the existing structured three-dimensional building, a method of providing two-dimensional right spatial objects in XML, and expressing them as three-dimensional right objects efficiently. In addition, this study will discuss a method of creating right objects in a way in which an owner who was provided with a cross section of a building involves the direct detailed right objects in additional production or reproduction to utilize three-dimensional data (right objects) produced through this study.

In an apartment house In Korea, the balcony is one of the important spaces as a buffer zone for controlling the outdoor environments such as noise, heating & cooling load, humidity etc. Because most areas of building facade in apartment building occupy the area of balcony window the sound Insulation design of It Is very Important to provide the quiet indoor environment. The aim of this research is to evaluate the sound insulation of balcony windows in apartment building by new and revised Korean Industrial Standards. We measured and studied the sound insulations of 18 balcony windows by the type of measuring methods, noise sources, correction of reverberation time in balcony and so on. The results show that the single-number quantities for sound insulation of windows are ranged from 24 dB to 30 dB.
This study analyses characteristics of space to facilitate community centering on cases of collective houses in Japan and uses the results as basic data to activate collective houses as an alternative form of housing in our country. To identify the characteristics of space for active communities with collective living space, this study conducted a theoretical examination on collective houses and housing, derived territoriality, accessibility, comfort and safety as factors of community activation and analysed various cases, and the results are presented as follows: First, territoriality is a necessary condition for formation of community, and a confined and physical space. It indicates the proper size of a space and diverse spacial areas which meet the needs of residents with the proper size and amount of space (space which can accommodate diverse generations including women, the aged and the young, flexible space which changes according to the purposes and program, space which supports leisure and hobby activities, and space which can accommodate outsiders). Second, accessibility indicates an environment which supports residents' easy use of space. As the more accessible it is, the higher the frequency of its use, spatial factors (piloti, backyards, benches and tables) should be provided, community space should be arranged in a central or decentralized way and community living space should be made for each floor. As for exits, accessibility should be considered in every way; entrances connected with community spaces, open entrances and entrances accessible from outside or individual living spaces. Third, comfort satisfies the physical and mental needs of residents through separation of floors and flows between the community and individual spaces for privacy and formation of eco-friendly spaces including vegetable gardens, gardens and plant arrangements. Fourth, safety should be considered for a higher quality environment with psychological stability and comfort, for which the following are recommended: installation of hand-rails, removal of thresholds, spacial design for the socially weak, duplex and open type structures for community space, open stages and halls, as well as indoor and outdoor openness through the use of windows.
The purpose of this study was to examine the characteristics of change in the composition of indoor spaces in Korean-style houses which have been repaired and improved extensively through the 'Bukchon Improvement Project' and are being utilized for public purposes. For this, we conducted a field survey through visiting the house sites from the 5th to the 26th of May, 2006. Conclusions drawn from this study are as follows. Bukchon Korean-style houses maintain centripetal space composition, in which the rooms surround the court. Centering on the court, the hierarchy of spaces is determined, and the hierarchy of spaces and the composition of internal layout are restructured centering on the court and the main hall without change in direction and position. The main hall is sometimes converted to a room, but it maintains an open space relation with other spaces centering on the court, and therefore, even after its use has been changed, it is still the most Korean-style space. In addition, with floor heating, the common sitting-style life is maintained continuously although the rooms have been converted and standing-style furniture is used. In this way, publicly promoted policies for Korean-style houses are allowed within the limit that the appearance is maintained and the internal spaces do not change the overall structure. However, in order to maintain the tradition of Korean-style houses and utilize them as various spaces, the following supplementations are necessary. First, the main hall and the inner court of a Koreanstyle house should be utilized actively. The court sometimes keeps individuals' privacy or expands the space by extending the view to outdoor spaces, and is sometimes used as an open space through interconnection between the inside and the outside of the house. Second, consideration should be given to vertical spaces. Horizontal expansion causes a change of floor plan. Thus, space should be secured using various cross-sectional changes, such as a kitchen and a loft over the kitchen. Third, structure should be changeable in order to adjust the size of spaces. Thus, through research on traditional windows, we need to develop changeable walls that can be installed and removed easily according to the use of spaces.

Many applications in the area of location-based services and personal navigation require nowadays the location determination of a user not only in outdoor environment but also indoor. To locate a person or object in a building, systems that use either infrared, ultrasonic or radio signals, and visible light for optical tracking have been developed. The use of WiFi for location determination has the advantage that no transmitters or receivers have to be installed in the building like in the case of infrared and ultrasonic based location systems. WiFi positioning technology adopts IEEE802.11x standard, by observing the radio signals from access points installed inside a building. These access points can be found nowadays in our daily environment, e.g. in many office buildings, public spaces and in urban areas. The principle of operation of location determination using WiFi signals is based on the measurement of the signal strengths to the surrounding available access points at a mobile terminal (e.g. PDA, notebook PC). An estimate of the location of the terminal is then obtained on the basis of these measurements and a signal propagation model inside the building. The signal propagation model can be obtained using simulations or with prior calibration measurements at known locations in an offline phase. The most common location determination approach is based on signal propagation patterns, namely WiFi fingerprinting. In this paper the underlying technology is briefly reviewed followed by an investigation of two WiFi positioning systems. Testing of the system is performed in two localization test beds, one at the Vienna University of Technology and the second at the Hong Kong Polytechnic University. First test showed that the trajectory of a moving user could be obtained with a standard deviation of about ${\pm}$ 3 m.

With increased social participation of married women and with the notion of importance of pre-school childhood on human development, the importance of nurseries is being emphasized. The transformation of the traditional family system into a nuclear family system and the deterioration of the traditional child education have also put nurseries as a primal social interest. But, at present, at the end of 1994, only 10% of the children have benefitted from such facilities, the supply not being able to meet demand. Also, the spatial organization and the management of such facilities has been unsatisfactory. In this perspective, this study aims to grasp the present condition of nurseries, to investigate and analyse case studies, to suggest standards and reform measures, and based on these, to produce basic information for the formation of an architectural spatial model. We've selected investigation of present conditions and case studies, interviews, and observation as investigative methods and through these we've assessed tangible spatial planning and spatial proportion by parts. 1. The most preferred grouping method is toddler/preschooler type, and the group size and staff-to-child ratios vary according to the children's age 2. The younger children's activity rooms are located in the lower level, and the activity room of the children on the similar development stages are located adjacent to one another 3. Most of the facilities do not have the public spaces(indoor playrooms, dinning rooms, napping rooms, bathrooms, sickrooms) For dinning and napping, activity rooms are being used, and for sickrooms, director's room or staff rooms 4. As for the correlations of the spaces(home bases, activity rooms and its outdoor spaces, day-care-centers and its community), closed plan type is 90% over, and modified open plan is 10% min.

Shopping malls have been developed to increase sales revenue and attract visitors. This study focused on the sense of the outdoor characteristics of these shopping malls by comparing open and enclosed types of shopping malls in common spaces in LA and Korea through case study analyses. This research through case studies will form the foundation of comfortable shopping mall space design. The results are the follows. 1. Enclosed shopping malls tend to provide large indoor space to create a sense of outdoors. 2. The common space of enclosed shopping malls is developed through space expansion with horizontal and vertical connections that appear in different combinations depending on the space constraints and contexts. 3. The architectural planning of enclosed shopping malls are largely dependent on the concept of everyday life portrayed in the identity of each space, which usually involve the inclusion of sizable atriums to host indoor sports or special performances.
The aim of this study is to understand the modernization process of interior spaces in the Korean housing, focused not only on the architectural aspects, but also on the sociological, anthropological and feministic aspects of housing. The development of korean housing from the period of traditional agricultural society and Japanese domination through the period of industrial development to the period of modem industrial society have been reviewed not from the Point of westernization but from the point of Korean own needs for modernity. It also tried to find the determinants of the relationship between social behavior patterns and space organization through historical change of housing plans. As a result, it was found the various western impacts to the continuation or change of Korean housing culture in the modernization process. Consequently this study comes to the concrete results as follows; 1) sociological aspect: The early layout of floorplans, that promoted the communication and contact between the user were changed. The layout of spaces in the modern housing tends to be not interdependence each other and be very isolated from the outdoor spaces. Those Phenomena reflect the trends to the Individualization, equivalence and privatization in the life of family. 2) feministic aspects: Differently from the early kitchen, modern ones locates in the internal space in the housing and the dinning area is appeared. And also the standing work at the kitchen war usually spreaded. Such changes are due to the emancipation of the women and downfall of the subordinate relationship between the genders. 3) anthropological aspects: The lifestyle, in which the user was mostly sitting on the floor, was constantly disappeared by using of furnitures that determines the function of each spaces in the housing. Those change demonstrate the change of behavior Patterns, thus, the needs of differentiation of function as well as the feministic needs. In other word, the coexistence of both fields of work and relax is required. 4) tectonic aspects: In the indoor space of modern housing the rooms are closed each other. Thus, concentrated circulation system act to separate these spaces. It is concrete spatial element that mostly shows the synthetic character of modem housing.

This study was conducted to investigate the efficiency of the filtering sets composed of fiberboards, which were fabricated with lignocellulosic fiber and cork oak bark-based activated carbon (COA), as well as traditional Korean paper handmade from mulberry trees (KP) for the filtration of PM, TVOC and HCHO. Three-layers fiberboards (WRF) were fabricated with wood fiber in its surface layers and recycled fiber/COA in its core layer using a protein-based adhesive with the resin content of 8%. Filtering sets were composed of three WRF and one sheet of KP. Concentrations of PM, TVOC and HCHO generated with the combustion of a incense in a sealed laboratory hood were reduced efficiently with the operation of air-purifier installed the filtering sets. Except for the WRF fabricated with 4%/4% resin contents, other WRF were prepared with 5%/3% and 6%/2% resin contents in surface/core layers, and then the WRF were used with KP for the fabrication of filtering sets. Filtration efficiency of the filtering sets was improved as the core-layer resin content applied in the fabrication of WRF decreased. In addition, filtration efficiency of the WRF-based filtering set fabricated with KP of 25 g/m2 basis weight was higher than that with KP of 45 g/m2 basis weight. Filtering sets composed of three-layers fiberboards (RWF) that recycled fiber and wood fiber/COA were used in its surface and core layers, respectively, and KP-25g showed higher filtration efficiency than those of WRF-based filtering sets. Air-inhalation equipment installed the RWF-based, WRF-based filtering sets and without filtering set were operated in small indoor and large outdoor spaces. Efficiency for filtering PM and TVOC of the RWF-based filtering sets was higher than that of other filtering sets. It is concluded that fiberboard-based filtering sets composed of RWF and KP-25g can be used as a filter for reducing the concentrations of PM and TVOC existed in indoor and outdoor spaces.
