A fuzzy rule-based hand-motion estimation algorithm is proposed for a 6 dimensional spatial tracker in which low cost accelerometers and gyros are employed. To be specific, beginning and stopping of hand motions needs to be accurately detected to initiate and terminate integration process to get position and pose of the hand from accelerometer and gyro signals, since errors due to noise and/or hand-shaking motions accumulated by integration processes. Fuzzy rules of yes or no of hand-motion-detection are here proposed for rules of accelerometer signals, and sum of derivatives of accelerometer and gyro signals. Several experimental results and shown to validate our proposed algorithms.

The purpose of this paper is to find out and discuss architectural factors for planning the cultural facilities for performing art. For the purpose, the Culture & Art centers in major cities are investigated. The investigation focuses on the analysis of efficient utilization and spatial composition of the Culture & Art centers. Generally the cultural facilities must be located on the site where people can easily access, and should have various kinds and sizes of rooms which people can use for various activities. However, most of the investigated Culture & Art centers are apart from the downtown of the cities, and do not provide the varied spaces. In particular, the sizes of performing halls are too large, and this makes the ratio of room use frequency and the occupancy of seat to be low. To encourage people to use the Culture & Art Centers, the program managers should arrange various programs which reflect the needs of people, and the clients and designers should decide proper room sizes and functions through appropriate analyses of the facilities.

To construct GIS successfully, mapping technology, primary S/W technology, and DB tool technology are necessarily required. Among them, the mapping technology is the most important one in constructing a GIS spatial database that needs much time and effort. In this paper, we designed and implemented a systematic and effective vectoring tool. The general vectoring process was analyzed and parted into an automated part and a remaining part for increasing overall efficiency. We also proposed a multi -level representation method for vector data and applied it to the developed vect1lring tool. We could verify usefulness of the proposed representation method.

Having been speed development of The Information Technology, Local Governments have been constructed the GIS(Geographical Information System) for supporting regional development. This paper will intend to find the problems of constructing spatial DB, the scheme of solving the problems. In addition, this paper will intended to present the direction of establishing spatial DB, which reviewed the case of Naju City on constructing GIS.

As a society advances and develops more rapidly, there is a corresponding increase in an aging population; and therefore, transportation and transportation needs develop in a complicated way. In these times, medical rehabilitation services are required and the demands for these services will increase as time passes. Moreover, the scope of disability as defined by the government has been expanded owing to the welfare policy for the disabled. Therefore, the number of disabled who require medical services is on the rise. Along with an increase in medical rehabilitation demands, the necessity for medical rehabilitation increases as well and its role becomes more diverse on a wider spectrum. However, architectural studies on rehabilitation facilities have been insufficient and there are many problems currently in facilities operations. This study aims to present a spatial organization system along with required space that would form the basis for the most effective spatial plan and facility operation for rehabilitation hospitals.

In this study, I would like to inquire about the composition of oegi(外機) on the hip and gable roof. Oegi purlin compose the basic member of framework of a hip and gable roof in both sides roof, supporting the inside end of the side rafter. However, the oegi purlin is not simply used to form hip and gable roof. The effects of using oegi purlin have the advantages of spatial. The spatial advantages are the width of the toekan(退間) increases as the oegi purlin escapes from column row and to increase the ceiling height by becoming a point of staying the ceiling. That reflect the desire to expand indoor space due to changes in worship behavior. Oegi purlin was used not only for structural needs, but also for altering in indoor space due to the changing times.

As a functionally complicated facility, it requires rational strategy to accommodate multi-functional needs to plan a hospital. Ambulatory surgery units located in large hospitals have problems such as longer waiting time and congestion for patients due to complicated planning and organization within limited area, which raise needs for independent ambulatory surgery centers to enable smoother medical treatment for patients. To design an independent ambulatory surgery center, understanding of zoning and layout of each unit needs is particularly required. This study focuses on research of efficient zoning/organization of day surgery unit and circulation arrangements of ambulatory surgery centers by analyzing various examples abroad, which will eventually help finding appropriate way of planning domestic ambulatory surgery centers. Specific area of research includes ambulatory surgery process, programmatic requirements, spatial organization of the facility, layout of surgery unit and circulation arrangements of ambulatory surgery centers.

GML (Geography Markup Language) has become the widely adopted standard for transport and storage of geographic information. So, various researches such as modeling, storage, query, and etc have been studied to provide the interoperability of geographic information in web environments. Especially, there are increased needs to store semi-structured data such as GML documents efficiently. Therefore, in this paper, we design and implement a GML repository to store GML documents on the basis of GML schema using spatial database system. GML Schema is converted into directed GML schema graph and the schema mapping technique from directed schema graph to spatial schema is presented. Also, we define the conversion rules on spatial schema to preserve the constraints of GML schema. GML repository using spatial database system is useful to provide the interoperability of geographic information and to store and manage enormous GML documents.

Map databases for CNS (Car Navigation System) can be accessed quickly and compressed efficiently due to that these are usually recorded as in a PSF (Physical Storage Format). However, it is difficult to create and manage data storage based on a file-system. To solve these problems, DBMS needs to be combined with spatial data management. Therefore, we developed an embedded DBMS with which to store data and conduct quick searches in CNS. Spatial data could be easily managed and accessed using the compression method, Multi-Link, spatial index, and spatial division. In the result, the proposed embedded DBMS searched quickly and stably supported data management. If synchronization is applied in DBMS, it is expected to utilize the advantages of an embedded DBMS.

This study starts form the inequity of the spatial accessibility in social services. This study has purpose to descript and analyze the spatial accessibility of social service agencies. While analysing the spatial accessibility, this paper uses comparative method of distance and space-time measures. The results of research are as follows; It needs (1) to enhance the spatial accessibility of the aged and the disabled. (2) to facilitate the spatial accessibility of marginal area or community like rural community. (3) to recognize utilities of distance and space-time measures in the spatial accessibility.
