This paper is intended to propose a novel approach to select an optimal site for a small-scaled artificial recharge system installation using TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) with geospatial data. TOPSIS is a MCDM (Multi-Criteria Decision Making) method to choose the preferred one of derived alternatives by calculating the relative closeness to an ideal solution. For applying TOPSIS, in the first, the topographic shape representing optimal recovery efficiency is defined based on a hydraulic model experiment, and then an appropriate surface slope is determined for the security of a self-purification capability with DEM (Digital Elevation Model). In the second phase, the candidate areas are extracted from an alluvial map through a morphology operation, because local alluvium with a lengthy and narrow shape could be satisfied with a primary condition for the optimal site. Thirdly, a shape file over all candidate areas was generated and criteria and their values were assigned according to hydrogeologic attributes. Finally, TOPSIS algorithm was applied to a shape file to place the order preference of candidate sites.

Ad hoc networks play an important role in mobile communications, and the performance of nodes has a significant impact on the choice of communication links. To ensure efficient and secure data forwarding and delivery, an intelligent routing protocol (IAODV) based on learning method is constructed. Five attributes of node energy, rate, credit value, computing power and transmission distance are taken as the basis of segmentation. By learning the selected samples and calculating the information gain of each attribute, the decision tree of routing node is constructed, and the rules of routing node selection are determined. IAODV algorithm realizes the adaptive evaluation and classification of network nodes, so as to determine the optimal transmission path from the source node to the destination node. The simulation results verify the feasibility, effectiveness and security of IAODV.

This paper describes a motivation-based hierarchical behavior planning framework to allow autonomous agents to select adaptive actions in simulation game environments. The combined behavior planning system is formed by four levels of specification, which are motivation extraction, goal list generation, action list determination and optimization. Our model increases the complexity of virtual human behavior planning by adding motivation with sudden and cumulative attributes. The motivation selection by probability distribution allows NPC to make multiple decisions in certain situations in order to embody realistic virtual humans. Hierarchical goal tree enhances the effective reactivity. Optimizing for potential actions provides NPC with safe and satisfying actions to adapt to the virtual environment. A restaurant simulation game was used to elucidate the mechanism of the framework.

The purpose of this study is to crystallize the factors which influence the eating-out tendency at home and work site including in the range of Daegu city. We can find out that taste is the most important element for family eating-out style. Then comes sanitation, service, reputation of a restaurant and price in that order. There are some differences between family eating-out style and workers eating-out style. The only thing that differs from above referred to statement is that price is prior to the reputation of a restaurant. Thus, taste is more important than any other factor in investigative studies. And, in case of family eating-out style, the reputation of a restaurant is prior to price. In case of workers eating-out, however, price is more important than the reputation of a restaurant.

The recent Web service field emerges as the fastest growing IT paradigm as a result of the increasing interest in SOA (Services-Oriented Architecture) and the expansion of B2B market. With an increasing number of Web service that provide similar features, it becomes more important to provide the most appropriate service for the user's request. A service user in general requires the quality information of Web service when selecting a service among a number of similar Web services. Yet, finding a service through UDDI (Universal Description, Discovery and Integration) does not consider the non-functional aspects of users because it is only based on the functional aspects. That is, the quality, non-functional aspect will be an important factor for the mutual success of the user and provider. Using 3 factors in the Qos factors of the existing studies: the execution cost, reliability, and the quality level, the QoS of Web service is saved and the factors for the QoS are recorded in order to consider non-functional factors when selecting a Web service in this study. The Quality Broker determines the rank and shows the desired result of the service for users. The Quality Broker suggested in this thesis can be used to select a Web Service that considers the user-oriented and non-functional factors.

This study aimed at categorizing food product consumer's life types, understanding properties of each type, identifying differences in the food consumption pattern, and suggesting a strategical plan to implement market segmentation for the future food products. A demonstrative analysis revealed that consumption tendencies of the sample group in the Busan area could be categorized into four types-popular brand orientation, convenience and practicality orientation, and change and innovation oriention; an analysis of demographical differences in each group demonstrated that variabes of age and family formation showed a significant difference within a significant level. A test of differences in the significance among food consumption types in each group demonstrated that there was no signifcant difference in the number of dining-out, average cost of dining-out per person, dining-out of the week, cost of dinner, and attributes of food service selection. To the contrary, there was a significant difference in the purpose of dining-out, place of lunch, cost of lunch, menu of dinner, and food service information medium among consumption tendencies of each within a significant level.

Recently, medical market has been changing not for the sake of treatment of the disease but for high quality of health. Therefore, South Korea medical tourism service needs to understand and improve for the differences perceptions of medical tourists and health professionals for customer satisfaction. The purpose of this study is to understand the structure of medical tourism market through theoretical consideration and to suggest the factors which need to be taken precedence for improvement of South Korea medical tourism service through analysis differences between consumers and suppliers. To analyze the difference of awareness, we reconstructed the questionnaires focussing on evaluation factors and articles about medical tourists selection attributes and health professionals way to invigoration through previous research and precedence study. After that, we also collected the data based on reconstructed questionnaires. After we compared each collected responses from medical tourists and health professionals, also analyzed the differences of awareness by applying Johari's Window to those differences. In conclusion, there is no relation between medical tourist and health professionals about th differences of awareness in functional quality and cost that is a direct effect to transaction in current medical tourism of South Korea. In contrast, there are differences of awareness between a process which support medical tourism and technical quality. Therefor, we expect to invigorate medical tourism by innovation of supportive process and technical quality.

This study aimed to systematically adjust rural area development projects that have been carried out by a variety of government departments for activation of rural areas and overcome inefficient problems caused by the policies and projects promoted separately. As its alternative, this study aimed to explore efficient improvement scheme of rural villages associated with various projects. Major agriculture/rural policies and projects that have been promoted were classified by the target space of the policies and projects as Environment space, living space, and production space. Each space was categorized into five sub-items without duplication. By assessment results of rural area improvement level and preference by Analytic Hierarchy Process(AHP) method, maintenance of rural areas was classified into four types. And outer space structure was analyzed by using Space Syntax Method(SSM). Based on the analysis result above, facilities for improvement of rural villages were placed around representative facilities. Facility allocation was based on selection and concentration in terms of facility maintenance and on type attributes in terms of spatial aspects. And finally, alternatives schemes for setting up the basic direction of improvement of rural villages are local area characteristics and environmentally conscious business plan.
