In this paper, a plan-coordination architecture is proposed for multi-agent control in the fractal manufacturing system (FrMS). A fractal in FrMS is a set of distributed agents whose goal can be achieved through cooperation, coordination, and negotiation with other agents. Since each agent in the FrMS generates, achieves, and modifies its own plan fragments autonomously during the coordination process with other agents, it is necessary to develop a systematic methodology for the achievement of global plan in the manufacturing system. The heterarchical structure of the FrMS provides a compromised plan-coordination approach, it compromise a centralized plan-generation/execution (which mainly focuses on the maximization of throughput) with a distributed one (which focuses on the autonomy of each module and flexibility of the whole system). Plan-coordinators in lower level fractal independently generate plan fragments according to the global plan of higher level fractal, and plan-coordinators in higher level fractal mediate/coordinate the plan fragments to enhance the global performance of the system. This paper assumes that generation method of the plan fragments and the negotiation policy of the fractal is achieved by a simple process, and we mainly focuses on the information exchanging and distributed decision making process to coordinate the combinations of plan fragments within a limited exchange of information.

Module coordination(分數), which is crucially relevant to plan shape of a fortress and the location of its gates and chis(雉, protruding posts), have not been thoroughly studied, despite its importance in fortress system. While plan shape of Goryeo fortress features orderly placement of gates and chis, under medium-sized J oseon fortress doesn't follow it strictly. As a result, fortresses with various plan shapes greatly outnumber those of Goryeo. Especially, Gimhaeeupseong Fortress, which is a large-scale town wall, shows such a complicated plan shape, making it difficult to figure out its modular coordination. Presumably, the reason for J oseon fortress' complicated plan shapes, which doesn't follow the orderly modular coordination, is thought to be in its various geographical conditions. Also, it seems that the building of fortress with such various and complicated plan shapes was to deter enemies from intruding by confusing them. And various plan shapes of fortress are also figured out to be pertinent to street system of towns and positions of public offices.

An approach for collision-free coordination plan along designated paths of two robots in a common workspace is presented. Specifically, a notion of coordination space is introduced to visualize all the collision-free coordinations for the two robots. Then a problem is formulated and resolved in order to find the optimal coordination curve which trade off between safety of two robots and difference of degree of accomplishment.

This study shows organizational designs to increase the coordination between infrastructure and rolling stock operation organizations after rail reform based on wheel/rail interface and train/track interaction. Information sharing, face-to-face meeting, liaison role, task force, manager responsible for coordination, and team organization could help to coordinate infrastructure construction plan and train operation plan. It is necessary for the organizations to begin to study the interaction between track and train in Korean environments to make the coordination more efficient.

The purpose of this study is to provide information needed to the construction of the co-housing in the urban area. This study focused on the characteristics of co-housing in its planning process of private house & common space; 'economy', 'creativity' & 'sociality'. The object of this study is co-housing in 'Seongmi-san Village' in Seoul, which was built by a coordination company with residents' participation. The methods are investigating interview materials, floor plans of 9 households, & common space plans produced in the coordination process from the basic plan of private house & common space to the final plan. The results are as follows. 1) The size and plan of private house differed from each other. The water pipe location differed from each floor, so that there were difficulties in construction. In conclusion, these made no 'economy', but brought high 'creativity'. 2) The 'sociality' would be estimated as high because there were various types of resident participation; resident interviews on the planning, workshops for private housing plan, and workshops for common space.

In order to improve the reliability of power service and the effective management of distribution power system. DAS (Distribution Automation system) is widely used in KEPCO(Korea Electric Power Corporation) branch offices. Based on the present protective device coordination program which used in KEPCO. this study presents the new concept about both protective device coordination program maximizing the characteristics of DAS and development plan of protective device auto-coordination program with the merits of DAS.

Global warming caused by greenhouse gases is one of the foremost challenges in the international community. As an alternative to solve this problem, the importance of CCS (Carbon Capture and Storage) technology is increasing. However, due to the delay of European financial crisis recovery, some large-scale CCS projects were postponed. In turn, large-scale CCS projects in South Korea have not been launched as originally planned. Given these situations, it is important to review the latest R&D activities related to CCS in South Korea, and then adjust relevant national policy accordingly. The purpose of this study is to identify policy issues for the effective promotion of CCS technology in South Korea. Following the analysis of recent global trend on CCS policy, we evaluated the results and achievements from national CCS projects, which had been listed under the "Korean National CCS Master Action Plan (2010)". Especially, we tried to review the attainability for the original goal of each project. Through the present study, we identified the current status of CCS technology in South Korea and suggested efficient ways to be taken in order to increase efficiency in implementing national CCS policy in the future.

This study investigates the effectiveness of fashion coordination presentation formats when people buy apparel products online. This study conducted an online survey with 595 females who shopped online at the simulated website by a single apparel plan picture (n=189), coordination plane picture (n=187), and 3-D coordination image (n=216). For data analysis, factor analysis, Cronbach's alpha, MANCOVA, ANOVA, Duncan test, correlation analysis, and chi-square are used. The results of this study are: First, the hedonic shopping value was significantly the highest when respondents shopped at a 3-D coordination image shopping mall, the next highest-scored presentation type was the coordination plane picture, and the case of presenting only the single apparel picture was significantly the lowest. The utilitarian shopping value and information shopping value were higher in the coordination plane picture and the 3-D coordination image shopping mall than the single apparel picture. Second, transactions satisfaction was high when respondents shopped at a 3-D coordination image, coordination plane image, and single apparel image in decreasing order.

At the present time, interest in hydrogen is increasingly growing worldwide to tackle climate change. Korea also takes an action by announcing the first hydrogen economy implementation basic plan with the import targets of 22.9 million tons of hydrogen from oversea in 2050. To achieve this plan, it is very essential to establish an overseas hydrogen supply chain. In this paper, the study estimates the import price for hydrogen into basic scenario and comprehensive scenario, and also analyses economic feasibility considering price of the each technology.

유비쿼터스도시의 건설 등에 관한 법률이 2008년 제정되었고 이에 따른 종합계획이 2009년 11월에 확정되었다. 이에 지자체에서 수립하는 유비쿼터스도시계획의 제도적 요건이 마련되었다. 그러나 일선 지자체 및 관련사업 관계자들의 유비쿼터스도시계획의 이해부족과 제도 정착의 초기에 발생되는 혼선이 상당히 야기되고 있는 실정이다. 이러한 혼선은 특히, 기존 관련계획 들과의 중복여부와 연계수립부분에서 발생되고 있다. 이에 본 연구는 유비쿼터스도시계획과 관련계획과의 법제도 및 계획내용 등을 비교분석하여 유비쿼터스도시계획과 관련계획들과의 관계를 파악함으로써 향후 유비쿼터스도시계획과 관련계획간의 연계가능성에 대한 시사점을 제공하고자 한다.
