With the emergence of partnerships with private actors in public and cultural diplomacies, complexity in the relations among the various stakeholders involved has arisen, and yet the relevant research is insufficient to shed any beneficial light on such issues. By looking at public-private partnerships, the present study determined that resource dependence, trust, and risk are the main factors affecting the feasibility of partnerships, and inductively developed propositions on their effects. In an explorative case study, Germany (decentralized mode of governance) and South Korea (centralized mode of governance) were compared as exemplary contrasting system designs. The results revealed that risk and trust are likely to affect the feasibility of partnerships, whereas resource dependence is not. The following additional findings also were made: (1) there are cultural actors in a 'for profit, but with non-profit purposes' sector; (2) an interpersonal level of trust positively affects partnerships; (3) 'taking risks' brings about 'innovation'; (4) the existence of international commonalities between any two cases depending on the actors' shared role, whether public or private; (5) public actors' emphasis on mutual trust, program budget and execution, innovations coming from taking risks, commitment and ownership, and unexpected situations; (6) private actors' consideration of 'publicness' and grant-seeking or financial support as important incentives, and their desire that public actors to show more trust, professionalism, and ownership with less control over budget execution. With its qualitative approach and in-depth analysis, the present study yielded new insights, notwithstanding the relatively small sample data.

The coordination of a three-level supply chain consisting of a supplier, a retailer, and a discount outlet (DCO) is studied here. We assume that the product is sold in two consecutive periods a Normal Sales Period (NSP) and a subsequent Clearance Salvage Period (CSP). A benchmark case is studied Initially in which the supply chain is coordinated by a s1n91e agent. Thus, the supplier the retailer, and the discount outlet design a common system that allows centralized decision making about stocking quantities, markdown time schedules, and policies on disposing of leftovers to deliver the greatest possible expected supply chain profit. Next, we consider a decentralized supply chain. Here, decisions are made without coordination. The objective is to maximize an individual party's expected profits. The focus of the study is on the following questions: what factors make the coordination an effective approach for the supply chain? How do we coordinate the supply chain so as to maximize the supply chain Joint expected profit? These and other related study issues are explored in this paper.

In this paper, we propose a novel approach to decentralized motion planning and conflict-resolution for multiple mobile agents working in an environment with unexpected moving obstacles. Our proposed motion planner has two characteristics. One is a real-time collision prognosis based on modified collision map. Collision map is a famous centralized motion planner with low computation load, and the collision prognosis hands over these characteristics. And the collision prognosis is based on current robots status, maximum robot speeds, maximum robot accelerations, and path information produced from off-line path planning procedure, so it is applicable to motion planner for multiple agents in a dynamic environment. The other characteristic is that motion controller architecture is based on potential field method, which is capable of integrating robot guidance to the goals with collision avoidance. For the architecture, we define virtual obstacles making delay time for collision avoidance from the real-time collision prognosis. Finally the results obtained from realistic simulation of a multi-robot environment with unknown moving obstacles demonstrate safety and efficiency of the proposed method.

무선 메쉬 네트워크 환경에서 그룹통신은 동적으로 변화하는 중계 메쉬 노드, 서로 다른 도메인의 그룹 간 통신에 대한 접근 제어, 그리고 네트워크를 관리하는 중앙화된 관리서버의 부재 등의 문제로 인해 관리가 어려워진다. 그룹의 멤버 뿐 아니라 위상이 동적으로 변화하는 무선 메쉬 네트워크 환경에서의 다대다(many-to-many) 멀티캐스트는 각 그룹 관리자가 자신의 그룹 멤버를 독립적으로 관리하며 그룹간 통신을 제어하는 다수의 하위 그룹으로 이루어진 비중앙화된 구조에 기반해서 구성될 수 있다. 본 논문에서는 네트워크의 위상을 고려한 비중앙화된 그룹키 관리 기법을 제안한다. 제안하는 프로토콜에서 각 멀티캐스트 송신자는 아이디 기반 암호화 알고리즘을 이용해서 분산화된 방법으로 각 그룹키를 그룹 멤버에게 전달하게 된다. 아이디 기반 암호화 기법은 그룹 멤버 뿐 아니라 메쉬 노드의 동적인 변화에도 효율적인 키관리를 가능케 하기 때문에 다대다 멀티캐스트 환경에서 키 갱신에 필요한 통신 회수 및 저장해야 할 키의 크기가 줄어드는 장점이 있다. 따라서 제안한 기법은 중앙화된 네트워크 관리자가 없고, 다수의 서비스 제공자가 그들의 그룹 통신을 독립적으로 관리하는 대규모의 동적인 메쉬 네트워크에서의 다대다 그룹통신 환경에 가장 적합하다.

This study provides comparative analysis on the parodying of the body and political powers in the traditional animation and Shrek Series based on the discourse of Foucault. For the research, parody theories and Foucault's discourse were reviewed through the literature study, and Shrek Series was analyzed through positive study. The Shrek Series overturned stereotypes of the traditional animation by means of parody, especially showing a true body and a political power in the post-modern society. Foucault focused on the body and newly changed political power in the post-modern society. A body was changed into resistant and combative forms rather than obedient and submissive under control of the community power. In addition, political power was changed into relationship-oriented, decentralized and creative power rather than the centralized and class-based. In the traditional fairy tales, heroes and heroines are beautiful and perfect characters who obtain wealth and honor and live a happy life forever. However, heros and heroines in the Shrek Series are not attractive and do not have the ideal body shape, but rather have creative and active personalities and show indifference towards wealth and honor. Furthermore, their dress colors show the change into lower value and higher chroma. The Shrek Series is a future-oriented animation which created a fluid body and a creative political power in the post-modern society.

Plug-in hybrid electric vehicles (PHEVs) will be widely used in future transportation systems to reduce oil fuel consumption. Therefore, the electrical energy demand will be increased due to the charging of a large number of vehicles. Without intelligent control strategies, the charging process can easily overload the electricity grid at peak hours. In this paper, we consider a smart charging and discharging process for multiple PHEVs in a building's garage to optimize the energy consumption profile of the building. We formulate a centralized optimization problem in which the building controller or planner aims to minimize the square Euclidean distance between the instantaneous energy demand and the average demand of the building by controlling the charging and discharging schedules of PHEVs (or 'users'). The PHEVs' batteries will be charged during low-demand periods and discharged during high-demand periods in order to reduce the peak load of the building. In a decentralized system, we design an energy cost-sharing model and apply a non-cooperative approach to formulate an energy charging and discharging scheduling game, in which the players are the users, their strategies are the battery charging and discharging schedules, and the utility function of each user is defined as the negative total energy payment to the building. Based on the game theory setup, we also propose a distributed algorithm in which each PHEV independently selects its best strategy to maximize the utility function. The PHEVs update the building planner with their energy charging and discharging schedules. We also show that the PHEV owners will have an incentive to participate in the energy charging and discharging game. Simulation results verify that the proposed distributed algorithm will minimize the peak load and the total energy cost simultaneously.

The information system of corporations are facing a new environment expressed by miniaturization, decentralization and Open System. It is therefore of utmost importance for corporations to adapt flexibly th such new environment by providing for corresponding changes to their existing information systems. The objectives of this study are to identify this new environment faced by today′s information system and develop effective methods for data resource management under this new environment. In this study, it is assumed that the new environment faced by information systems can be specified as Distributed Computing Environment, and in order to achieve such system, presents Client/server architecture as its representative computing structure, This study defines Client/server architecture as a computing architecture which specialize the fuctionality of the client system and the server system in order to have an application distribute and perform cooperative processing at the best platform. Furthermore, from among the five structures utilized in Client/server architecture for distribution and cooperative processing of application between server and client this study presents two different data management methods under the Client/server environment; one is "Remote Data Management Method" which uses file server or database server and. the other is "Distributed Data Management Method" using distributed database management system. The result of this study leads to the conclusion that in the client/server environment although distributed application is assumed, the data could become centralized (in the case of file server or database server) or decentralized (in the case of distributed database system) and the data management method through a distributed database system where complete responsibility and powers with respect to control of data used by the user are given not only is it more adaptable to modern flexible corporate environment, but in terms of system operation, it presents a more efficient data management alternative compared to existing data management methods in terms of cutting costs.

This paper aims to research the historical development of the archival systems in the Soviet Union from 1917 to the 1920's. The Russian revolution was the turning point not only for the political and social changes but for the archival administration in Russia, as it provided the new Soviet regime with the chances to reorganize the archival institutions under Bolshevik rule. However, we must not forget the fact that the Russian Archival Workers' Union had taken part in the organization of the archival systems together with the Bolshevik revolutionaries. The Soviet government intended to transform the decentralized and poorly organized archival systems in the prerevolutionary years into the centralized and bureaucratized ones. In this meaning, the decree signed be V. I. Lenin on 1 June 1918 was estimated as the real basis for the Soviet archival centralization. Lenin's archival decree of 1918 encompassed the entire national documentary legacy, which was gradually extended to all types and categories of manuscripts and archival records by successive legislation. The concept of state proprietorship of all documentary records was designated "Single State Archival Fond"(Edinyi Gosudarstvennyi arkhivnyi fond), which was renamed as "Archival Fond of the Russian Federation" after the collapse of the USSR. The independent state administrative agency, that is, "Main Administration of Archival Affairs"(Glavnoe upravlenie arkhivnym delom) was charged with the management of the entire "Single State Archival Fond". While the Soviet Union reorganized its archival systems in the twenties, the archival institutions became under the severe control of the government. For example, M. N. Pokrovskii, the well-known Marxist historian and the political leader, headed the organizational work of archives in the Soviet Union, which resulted in the exclusion of the prerevolutionary specialists from the archival field in the Soviet Union. However, the discussions over the concept of "the Archival Fond" by B. I. Anfilov helped to develop the archival theories in the USSR in the twenties. In conclusion, the Soviet Union, having emphasized the centralization of the archives, developed its archival systems from the early period, which were the basis of the systematic archival institutions in Russia.

현재 우리나라의 국가안전관리(위기재난관리)체계를 지탱하고 있는 기본법은 '재난 및 안전관리기본법'이다. 이러한 '재난 및 안전관리기본법' 하에서 우리나라의 국가안전관리체계는 위기와 재난을 효율적으로 관리하기 위하여 이른바 삼단체계(중앙정부, 시도, 시군구)를 채택하고 있다. 통합위기관리체계(IEM)는 일차적으로 지역 대응기관의 조정과 협력(Coordination and Cooperation)체계를 중시하는 개념이며, 특히 서로 동등한 위치에서 기관과 기관 간의 협력을 강조하고 있다. 이러한 통합위기관리체계의 흐름에 발맞추어 영국과 미국의 국가안전관리체계는, 지역사회 내의 지역대응기관들이 중앙정부나 연방정부의 직접적인 개입없이 일차적으로 시민보호와 관련된 문제(위기 및 재난)를 관리하는 시스템을 구축하고 있다. 다시 말해, 영국과 미국에서는 위기와 재난의 범위가 아주 광범위하고 복잡한 경우, 이로 인하여 중앙정부의 조정과 협력이 절실히 요구되는 때에만 비로소 중앙정부의 개입이 직접적으로 이루어지고 있는 것이다. 이와 반대로 한국의 국가안전관리체계는 지시와 통제(Command and Control) 중심의 중앙집권화 된 시스템을 채택하고 있기 때문에, 위기재난 발생시(중요도에 관계없이) 중앙 정부가 쉽게 지역단위의 지휘체계를 무시하고 이를 통제하고 간섭할 수 있다. 현대사회는 불확실성, 비친숙성 및 비예측성이 증폭되고 있는, 이른바 '위험사회(Risk Society)' 또는 '포스트모던 사회(Post-modern Society)'라고 일컬어진다. 이러한 불확실성의 시대에서 과연 우리의 하향식 국가안전관리체계가, '위험사회(Risk Society)'와 '포스트모던 사회(Post-modern Society)'의 불확실성, 비친숙성, 비예측성을 효과적으로 관리할 수 있는지 의문점이 제기된다. 이러한 맥락에서, 동 논문은 한국의 시민보호체계도 영국과 미국의 위기재난관리시스템과 마찬가지로 분권화된 조정과 협력모델(Coordination and Cooperation)로 변화해야 한다고 주장한다. 이를 위해서, 현행 '재난 및 안전관리기본법' 체계 하에서 우리나라의 시민보호체계 및 안전관리체계를 비판적으로 검토하고, 이를 토대로 국가안전관리체계의 발전 방향에 대한 정책적 시사점을 제시하고자 한다.
