Communication infrastructure of wireless sensor networks significantly tends to depend on application requirements. Gossip communication is becoming one of the promising solutions for addressing its scalability problems in providing information propagation functionality based on the P (publish)/S (subscribe) paradigm. In particular, despite the importance of both guaranteeing message delivery order required and supporting overlapping groups in sensor networks, there exist little research works on development of gossip-style dissemination protocols to satisfy all these requirements. In this paper, we present the latest causal information transmission protocol between publishers and subscribers for overlapping groups. In this protocol, sensor leaders as publishers might guarantee consistently causally ordered message delivery among themselves by aggregating causality information. On the other hand, only the latest causal information piggybacked on each multicast message is transmitted from publishers to subscribers through gossip-style dissemination. Its scalability feature might be highly suitable for the area of the applications requiring only the minimum meaningful information.

This study identified the present state of store and selection criteria of supplier from the regional fashion buyer point of view and examined the effects of the factors of relative impact between buyer and supplier on the relational bond. The interviews and questionnaires were administered to the owners or the sellers of 85 fashion retail stores in Gwangju. For analysis of data, frequency, means, factor analysis, Cronbach's ${\alpha}$ and regression analysis were applied. The results were as follows. First, in the results of examining the actual conditions of store managers for fashion buyers, fashion buyers complained about lengthy travelling and time consumption inconvenience. They also reported decrease in margin and monthly mean sales over last year. Second, the most important selection the criteria for the supplier were product power, followed by a convenient store layout. Finally, higher quality communication, more compromises, and higher dependence were affected with higher satisfaction, trust, and commitment in suppliers; conversely, the trust and commitment of the buyers decreased relative to the increased power of the suppliers.

Since the year of 2003, the overseas plant market has grown by an average of 6% per year. It is because of the increase of oil-money, economic growth of BRICs, and the result of heavy competition among the countries which demands a great amount of resources for the purpose of resource securing. Such a situation is expected to be continued for a while. The procurement is one of critical functions for successful completion of a plant project. For effective procurement, it is required to manage vendor's information efficiently. But most of the vendor management systems deal with simple general information and performance data about vendors. In this sense, this paper proposes a vendor management system which can be used within a decision-making system. The system uses existing DB and makes the close relationship with the vendors. This paper will also reduce risks and difficulties in the process of selecting the proper vendors and will increase efficiency of procurement process in electronic bidding between companies.

본 연구는 다양한 통제메커니즘이 관계의 질에 미치는 영향과 환경불확실성의 조절효과를 분석하고 있다. 국내 모 백화점의 202개 공급업체를 대상으로 한 서베이 분석결과, 위 연구문제들에 대한 해답은 명쾌하게 제시되고 있지 않다. 첫째, 관계의 질에 가장 큰 영향을 미치는 변수는 조직간 통합인 것으로 나타났다. 조직간 통합은 신뢰, 만족, 장기거래의지를 모두 증가시키는 것으로 나타났다. 둘째, 인센티브로서 공급자의 거래특유투자가 많을수록 만족과 장기거래의지는 증가하는 것으로 나타났다. 셋째, 자격제한과 감시의 주효과와 환경불확실성의 조절효과는 없는 것으로 확인되고 있다. 결론부분에서는 이상의 연구결과가 구매자-공급자간 거래에서의 통제메커니즘의 활용과 관련하여 가지는 이론 및 실제적 의의와 시사점을 기술하고 있다.

Buyers are transforming their relations with suppliers. For examples, Instead of playing off dozens or even hundreds of competing suppliers against each other, many firms are finding it more profitable to work closly with only a small number of ＂partners＂. If will facilitate a move from single-supplier arrangements(＂hierachies＂) to mutiple supplier arrangement(＂markets＂) because it reduces the costs of coordination with suppliers. According to this logic, Technological developments which lower the cost of acquiring information about prices and product characteristics in a given market should increase to the nymber of tends to lower coordination costs, it wide adoption should lead to an increase in the number of suppliers for most firms, other things being equal. An efficient merket is defined a one that reduces the numer of intermediaries, or the number of Intermediary steps necessary of market tracsaction. It is true that one can order some products via mail order, which reduces the number of intermediaries and cuts transaction costs further Similary, the growth of a global commerce nerwork such as the internet may futher reduce the number of intermediary steps necessary for trade.

The purpose of this study is to investigate the moderating role of customer and supplier participation in the relationship between new product/service development processes and product/service innovation. The research result shows that the high customer participation plays the moderating role in the relationship between strategy design and product/service innovation. Thus, if customers give ideas in the strategy design process, the probability of new product/service innovation will be increased. The conclusions and implications are discussed.

인터넷으로 인해 고객, 공급자, 기업 등이 상호작용하는 방식이 변화되고 있다. 인터넷은 새로운 사업 기회를 제공하는 한편, 새로운 경쟁적 위협을 암시하고 있다. 인터넷으로 인해 기업은 고객, 공급자, 제휴 파트너 등과의 관계를 재정의함은 물론이고, 기업 내부의 작업방식, 부서간의 장벽을 없애고 그 기능을 재정의하기에 이르고 있다. 가상사회에서는 더 이상 소비자가 전화로 음악 CD나 사전을 주문하고 지로로 입금을 하고 택배로 제품을 수령하는 방식으로 사업이나 거래가 이루어지지 않는다. 소비자는 인터넷에 접속하여 원하는 주제의 음악이나 사전의 한 부분만을 주문하고 신용카드나 전자화폐로 대금을 지불하고 자신의 컴퓨터에 직접 제품을 내려받아 사용하게 된다.

With Recently in art and culture domains, there's rising controversy over shared economy and public domain works. The government is introducing institutional measures such as Gongumadang and KOGL(Korea Open Government License) program to expand the grounds for public domain works. In order to promote and facilitate the use of public domain works, it is imperative to understand how the providers who create and provide the public domain works, as well as the users, perceive shared economy and public domain works. However, preceding studies usually put emphasis on the meaning and significance of the shared economy and show limitation of not discussing providers' perception on shared economy and public domain works. Therefore, this study examines to see if there's a difference of perception between the consumers/users and the providers who owns the copyright of public domain work.
