GIS is a powerful toolbox in managing spatial data associated with attribute data. However GIS is short of spatial analysis function and graphic user interface(GUI) function in dealing with dynamic planning problems. Decision Support Systems(DSS) make up for the shortage of GIS by providing GUI function, modeling function and database function. Spatial Decision Support Systems(SDSS), a new kind of DSS, incorporate display function, basic spatial analysis function and manipulation function of spatial data and attribute data of GIS and GUI function, modeling function and database function of DSS in dealing with spatial planning problems. Planning Support Systems(PSS) add more advanced spatial analysis function and intertemporal function to the functions of SDSS. This study focuses on the modeling of a PSS for capacity expansion of water-distribution network depending upon land use planning by using GIS, value engineering(VE) and life cycle costing(LCC). The PSS shows a guideline about the investment of water-distribution networks related to urban growth management through generating certain numbers of dynamic alternatives to supply the amount of water caused by land use planning.

As the industrialization and urbanization are advanced rapidly, the apartment housing has been in excessive supply. Also, the apartment housing that offers modern people a comfortable life has been the typical housing type in Korea. Meanwhile, people today have lost their morality and communities have been dissolved because of a sudden social change. But the lost morality can be recovered when the communities are established. As more increasing in the residents' demands, it is enlarging of residents' interests and participations in pursuit of quality of life. In this process, residents' participation has occurred of their free will not only in offline communities but also online communities. For developing of IT technology, people using internet have exceeded 75% and development of online communities in apartment housing have boundless potentialities despite in a delicate situation that is at the same time and same space. The purpose of this study is that examine the possibilities and directions of participation, as it attempts to grasp the present conditions and problems of online community. In the study, we searched the word, apartment housing, on portal site to apprehensive the status of residents' voluntary participation on online community. According to research, residents' voluntary participation on online community was divided into three frames, such as remodeling, planed resident and designing friendship. Finally we found out resident's contents of communication and structure of their participation by these frames. As a result, participation on online community helps residents who have been not take part in offline community because of limited time in spite of difficulty of lasting participation. From now on, it will have possibility to increase and revitalize new communities on the purpose.

Recently, healthy life has become an issue in an aging society, and the number of people who have been interested in continuous health care for better life is increasing. In this paper, we implemented a personalized recommendation systm to provide convenient healthcare management for user. The PHR (Personal Health Record) of user could be stored in the server along with health related information such as lifestyle, disease, and physical condition. The users could be classified into similar clusters according to the PHR profile in order to provide healthcare contents to the users who had similar PHR profile. K-Means clustering was applied to generate clusters based on PHR profile and ACDT(Ant Colony Decision Tree) algorithm was used to provide personalised recommendation of health information stored in knowledge base. The app system developed in this paper is useful for users to perform healthcare themselves by providing information on serious diseases and lifestyle habits to be improved according to the clusters classified by PHR profile.

This paper aims to approach a spatial furniture for sedentary lifestyle which been has derived and evolved from Korea's traditional 'Ondol' heating system. In this living culture, people has been staid on the floor where people would sit directly on without furniture such as chair and bed. With every changing technological advances, sedentary life culture is transformed and mixed instead of sedentary habit. Most of people lived in western house such as apartment forms. As time go by, western furnitures were used became widespread. However, during the process, it impossible to acclimate ourselves to the new lifestyle such as chair, bed etc. This leads to users feeling uncomfortable on certain points. The researcher suggests a spatial furniture through a new approach to rest-taking that also intersects the cultures of East and West while resolving the a fore-mentioned issues. The study is conducted as follows. Firstly, issues are discovered through a user's lifestyle to exist usage and interplay of house and furniture. Furthermore, the issues was not a fragmentary thing but more related to a culture and a coustom of long standing. Secondly, a design experiment is conducted to conclude a new form and function that is better fit for the Korean culture where sitting on the floor is the norm. New direction for space that intersects the cultures of the East and West while using modules made convenient for contemporary life is presented. Finally, this study is meaningful in that it reinterprets furniture used for rest within the context of sedentary culture, in order to propose a new direction and value for design that overcomes the boundaries between eastern and western applied to resting space.

We developed a user-friendly program to independently verify monitor units (MUs) calculated by radiation treatment planning systems (RTPS), as well as to manage beam database in clinic. The off-axis factor, beam hardening effect, inhomogeneity correction, and the different depth correction were incorporated into the program algorithm to improve the accuracy in calculated MUs. A beam database in the program was supposed to use measured data from routine quality assurance (QA) processes for timely update. To enhance user's convenience, a graphic user interface (GUI) was developed by using Visual Basic for Application. In order to evaluate the accuracy of the program for various treatment conditions, the MU comparisons were made for 213 cases of phantom and for 108 cases of 17 patients treated by 3D conformal radiation therapy. The MUs calculated by the program and calculated by the RTPS showed a fair agreement within ${\pm}3%$ for the phantom and ${\pm}5%$ for the patient, except for the cases of extreme inhomogeneity. By using Visual Basic for Application and Microsoft Excel worksheet interface, the program can automatically generate beam data book for clinical reference and the comparison template for the beam data management. The program developed in this study can be used to verify the accuracy of RTPS for various treatment conditions and thus can be used as a tool of routine RTPS QA, as well as independent MU checks. In addition, its beam database management interface can update beam data periodically and thus can be used to monitor multiple beam databases efficiently.

This study has main purpose to understand the traditional house, not by outside researcher's but by inside dweller's view. The house in Geochang, is descendent house of Jeong-On who was faithful scholar at Chosen Dynasty. In order to understand, I restore firstly the house form and space at traditional era, 60 years ago, and every dwellers not only family members but also servants and guests, by interviewing old matriarch. One of the main rules of the house disposition is Ancester worshipping life. Worshipping floor of Anchae, main building, is located unusually in front of Shrine for Jeong-On, in order to connect all activities directly. Sarangchae, men's building, opened to the funeral mourners, is separated by a wall because women have to serve foods and wail at the backside. Space for everyday life is separated by man/woman, insider/outsider, master/subordinate. Agricultural production is also key factor of the space allocation: big storage buildings for rice crop needed to tenant farming. Both activities of ancestor worship ceremony and guest greeting need large kitchen annex area for food preparation and serving space of rear veranda floor. A number of guests visit the house: guest-greeting activity is taken place from the family pavilion, Neungheo-Jeong and Saranchae by the social position. This study show that architectural space and form of the house reflects exactly dwellers life.

Purpose: The gear strength of a new mechanical transmission designed to increase the loading weight of small 4.8 kW tracked agricultural transporters was analyzed. Design improvements to increase the gear strength and reduce the gear weight were proposed after examining the parameters. Methods: Sixteen operators from three regions were surveyed to obtain the usage profile of small 4.8 kW transporters. Gear strength was evaluated by calculating contact stress and tooth root stress using commercial software following ISO 6336. Results: From the strength calculation for each gear pair, contact stress smaller than tooth root stresses were produced in all gear pairs. The safety factors in most cases exceeded 1.0, except in the case of gear pair II in group II. The design life of the transporter using gear pair II in group II was 42% under harsh conditions-thus, this design life needs improvement. A robust design was proposed by examining the relevant parameters (face width and profile shift coefficient) to increase the design life of the transporter. In addition, a lightweight design for gear pair I in group II that was considered overdesigned was proposed by examining the face width to reduce the weight of the drive gear by 42% and that of the driven gear by 30%. Conclusions: The Safety factor for the design life was examined through a gear strength analysis. After examining the relevant parameters, conditions for strength improvement were proposed to increase design life or adjust overdesigned gear. However, load conditions differ depending on the working conditions or user's preferences; therefore, it is necessary to conduct further studies in various regions.
