오늘날 스포츠, RTS, RPG 게임과 같이 멀티 플레이어가 한 팀을 이루는 집단형 방식의 게임은 팀 인공지능 기술이 더욱 필요하다. 기존의 독립적인 지능형 에이전트는 스스로 문제를 해결하는 자율성 향상 연구에 치중하였으나, 이는 다른 에이전트간의 협동 및 상호작용 능력이 부족하다. 이를 위해 본 논문은 다중에이전트 시스템에서 효과적인 역할 분담과 자율성을 갖는 레벨통합 접근방식을 소개한다. 복잡한 목표를 성취하기 위해 에이전트의 역할 정보를 이용하여 각자의 목표를 할당하고 각 에이전트는 맡은 역할을 동적인 환경에서 스스로 판단하고 행동한다. 팀 전체의 목표는 상호 보완된 역할 분담의 전략적인 측면에서 조정한다. 각 에이전트는 데이터보드를 이용하여 서로의 상태 정보를 공유하여 상호 협동을 유도한다. 역할이 할당된 각 에이전트는 스스로 계획기능을 갖고 있어 동적인 환경에서 적합한 행동을 취한다. 이 협동과 상호작용 과정에서 충돌의 문제점이 발생하는데 이를 제어하는 조정 에이전트의 역할을 전략적 측면에서 접근한다. 본 논문에서 제시하는 레벨통합 접근방식이 기존의 중앙 집권적 접근방식, 분권적 접근방식과 비교 실험하여 기존 방식보다 성능이 향상됨을 보인다.

This paper describes depth, heading and speed control of an underwater vehicle that has four stern thrusters of which forces are coupled in the diving and, steering motion, as well as the speed of the vehicle. The optimal linear quadratic controller is designed based on a linearized- state space model, developed by combining the dynamic equations of speed, steering and diving motion. The designed controller gives provides an optimal thrust distribution, minimizing the given performance index to control speed, depth and heading simultaneously. To validate the performance of the controller, a simulation and tank-test are carried out with DUSAUV (Dual Use Semi-Autonomous Underwater Vehicle), developed by KORDI as a test-bed for testing new underwater technologies. Optimal gains of the controller are tuned, using a computer simulation environment with a nonlinear 6-DOF numerical DUSAUV model, developed by PMM (Planner Motion Mechanism) test. To verify the performance of the presented controller in experiment, a tank-test with DUSAUV is carried out in the ocean engineering basin in KORDI. The experimental results are also compared with the simulation results to investigate the accordance of the numerical and the real mode.

A number of the retail and traditional market customer is decrease, whereas that of the supermarket in department-store customers in is increase. This case suggests that customers have a preference for much more comfortable and pleasant shopping places And making a resonable purchase in the supermarkets where we can find various goods and price zone, is now garden variety. It is a current course that once the manager ask an architect for multi-functional space design in department-store and then the architect compose a team and start to design. Of course, the team of planner thinking manage give the design team the basic material data such as commerce analysis and the use of each layer in the department store but, the design team solve the assignment by architectural form, functional space plan and the limited architecture law. After establishing general design for architecture, we can ask shopping-mall distribution, products display and interior design of the interior design general design for architecture, we can ask shopping-mall distribution, products display and interior design of the interior design team. so it is inevitable that the interior design team concerning M·D can find lots of complementary factors with architecture design. The purpose of this study is analyzing the differences of architecture design, which has to accept the limited law and interior design concerning M·D, satisfying the structure and the law in the future design for the department-store. Also the purpose of this thesis is suggestion the items architects and interior designers research into together to make the inner space ideally.

The purpose of this study is to investigate, analyze the purchasing behavior of fashion goods according to life style and role model of preteen generation, and provide manager or marketing planner for the reference data so that they can understand preteen generation and make proper strategy efficiently. So called, preteen market focusing on 1014 generation (from ten to fourteen years old) is highlighted. This generation created between the year 1989 to 1993 after Seoul Olympic monopolize parent's love in abundant economic environment and rise to the core of consumption subject. Products aiming at this preteen generation continuously though consumption mind was shrunk greatly due to recession. Only 2~3 years before preteen market was regarded as grey zone which doesn't belong to not only children (between six and nine years old) but also teenagers (between fifteen to eighteen years old). But in recent day their purchasing powers have increased rapidly and age group is divided on details, so that preteen market has become a niche market. Subjects were 333 persons consisting of students in the 4th~6th grade of primary school and the 1st~2nd grade of middle school in Daegu city. Measuring instruments are as follows: 5questions to differentiate preteen generation, 22 questions to measure life style, 17questions (which have six sub-factors such as purchase motive, factor of product selection, utilization of informant, purchase time, purchase place, and purchase method) to measure the purchase behavior of fashion goods measurement, and 16 questions (which have four sub-factors such as parent, entertainer & sports stars, brothers and sisters, friends) to measure model of role. Statistical data were processed by SPSS 10.0 programs. Frequencies, Factor analysis, Cluster analysis, ANOVA, Cross analysis, Multiplex regression analysis, and Duncan's multiple range test were carried out.

Fishing village is becoming the central base of fishing industry and it plays a major role. However, there is a decrement of marine resources and some difficulties with the deterioration of fishing industry management. In order to solve these problems, there should be some developments(e.g. fishing village toursim development) on various undergoing government and the private organization programs. Nevertheless, there are not guidelines for fishing village tourism development to utilize for practical business. Therefore, it is necessary to understand the current status and guidelines regarding the development of fishing village for coastal planner. The primary purpose of this study is to investigate the characteristics of fishing village development works in Korea and Japan. The second purpose is to identifie success factors after analyzing individual success cases. Based on evidence from the literature and a dialogue with village leader, a literature review on extracting success cases for guidelines were selected according to criteria such as the degree of contribution to an increase in income of the fishing village, the degree of contribution to an increase in consumption of marine products using local natural resources, the number of tourists that visits the village. Finally we propose guidelines for future fishing village development projects. The guidelines based on the successful cases, as well as the major factors about the objectives and direction of fishing village tourism development, suggested as follows. 1)Plans for land use, 2)Development of tourist resources, 3)Plans for views, 4)Plans for resource protection, 5)Plans for operation and marketing.

This study is aimed at classifying different types of parks in Gwang-Ju city and providing efficient Planning and guidelines to satisfy the needs of park users. The first stage of this study was accomplished by site surveys of neighborhood parks in Gwang-Ju where park types, locations, neighboring conditions, park layout, and other physical environments were surveyed for the specific status of parks. With those basic data, urban neighborhood park types were classified into different categories: 1) urban neighborhood parks; 2) riverside neighborhood parks; and 3) natural(mountain side) neighborhood parks. For the second stage of this study, behavior patterns and satisfaction were investigated to provide empirical data on the relationship between the physical environment and human behavior. The main findings of this study can be summarized as follows: 1. The highest level of satisfaction for the users of urban neighborhood parks in Gwang-Ju city is the accessibility of the parks which are small but located in neighborhoods, The users tend to visit the nearby parks regardless of size. 2. The users have relatively high levels of satisfaction for urban neighborhood parks which have a lot of green zones or park facilities. Therefore, the park planner should consider the natural environment in the park area and should reconsider the type of park in the planning process. 3. The different types of urban neighborhood parks in Gwang-Ju city do not affect the level of satisfaction and the motivation of park visits. However, the accessibility of the parks is the most important factors of users' satisfaction regardless of the type of the park. 4. The level of user satisfaction for all of the urban neighborhood parks in Gwang-Ju city indicates that the users have a relatively low level of satisfaction. Especially, 26.2% of the users have a high level of dissatisfaction. The new parks, which have recently been developed, have a higher level of satisfaction than the old parks which have a lack of facilities, insufficient maintenance, and poor management planning in the park. 5. As a result of factor analysis, all city neighborhood parks showed a similar tendency with urban type parks, but showed a tendency that was different from the other park types.

축제의 양적 팽창에도 불구하고 지역축제에 대한 만족도는 몇몇 축제를 제외하곤 그리 높은 편이 아니다. 이는 지역축제의 본질적 목적에 비해 경제성을 강조한 나머지 지역축제의 개최목적인 지역관광산업의 발전, 지역문화의 보전, 지역주민의 여가기회확대, 지역공동체 의식의 함양, 지역이미지 제고 등을 고려하지 못한 축제들이 우후죽순 생겨나고 지역주민과 관광객의 만족을 높일 수 있는 행사내용과 형식들이 차별화되어 있지 못한 것에 기인한다고 볼 수 있다. 본 연구에서는 이러한 점을 고려하여 문화체육관광부의 축제평가기준을 토대로 제24회 김포문화예술제에 참여한 관광객과 지역주민에 대한 설문조사를 실시하여 지역축제 만족도 결정요인을 규명하고 이를 통해 지역주민과 관광객간의 재방문의도와 추천의도에 미치는 영향을 분석하여 향후 김포문화예술제가 성공적인 지역축제가 될 수 있도록 축제마케팅 전략수립에 유용한 시사점을 제공한다.

Adult stem cell transplantation has been increased every year, because of the lack of organ donors for regenerative medicine. Therefore, development of reliable and safety cryopreservation and bio-baking method for stem cell therapy is urgently needed. The present study investigated safety of dimethyl sulfoxide (DMSO) such as common cryoprotectant on porcine bone marrow derived mesenchymal stem cells (pBM-MSCs) by evaluating the activation of Caspase-3 and -7, apoptosis related important signal pathway. pBM-MSCs used for the present study were isolated density gradient method by Ficoll-Paque Plus and cultured in A-DMEM supplemented 10% FBS at $38.5^{\circ}C$ in 5% $CO_2$ incubator. pBM-MSCs were cryopreserved in A-DMEM supplemented either with 5%, 10% or 20% DMSO by cooling rate at $-1^{\circ}C$/min in a Kryo 360 (planner 300, Middlesex, UK) and kept into $LN_2$. Survival rate of cells after thawing did not differ between 5% and 10% DMSO but was lowest in 20% DMSO by 0.4% trypan blue exclusion. Activation of Caspase-3 and -7 by Vybrant FAM Caspase-3 and -7 Assay Assay Kit (Molecular probes, Inc.OR, USA) was analyzed with a flow cytometer. Both of cryopreserved and control groups (fresh pBM-MSCs) were observed after the activation of Caspase-3 and -7. The activation did not differ between 5% and 10% DMSO, but was observed highest in 20% DMSO. Therefore 5% DMSO can be possibly used for cell cryopreservation instead of 10% DMSO.
