This paper introduces the coded cooperation protocol in wireless relay network. We propose a two relay based coded cooperation protocol with RCPC codes for wireless networks. The proposed two-relay based system can achieve a diversity of order 4 under slow fading environment. Under fast fading, the diversity order is 2 times of the free distance of the convolutional code. We develop upper bounds on BER and FER for the system under both slow and fast fading with Rayleigh distribution. The effect of various channel conditions on the cooperation is also examined in this work.

Emergent requests or urgent information among enterprises require their intimate collaboration in B2B EC (electronic commerce). This paper analyzes the needs of intimate cooperation of distributed EC systems in terms of business contracts and presents an active rule-based methodology of close cooperation among EC systems and an active rule component to support it. Since the rule component provides high level rule patterns and event-based immediate processing, system administrators and programmers can easily program and maintain intimate cooperation of distributed EC systems independently to the application logic. The proposed active rule component facilitates HTTP protocol. Its prototype is implemented in B2B EC environment and evaluated using basic trigger facility of a commercial DBMS.

There is no prior research on organizational commitment and supervision for social welfare public officials in charge of public-private cooperation in public welfare fields. Therefore we are designed to determine the impact of social welfare public officials' public-private cooperation awareness on organizational commitment to verify the moderating effect of supervision on the effect between public-private cooperation awareness and organizational commitment. The analysis data is 242 questionnaires collected from Incheon public health and welfare officials visiting towns, villages, and villages in 10 counties. Using the SPSS 22.0 program, descriptive statistics and relationships between variables were analyzed, regression analysis was performed to analyze the influence between variables, and hierarchical regression analysis was performed to verify supervision control. As a result of the study, it was confirmed that the perception of public-private cooperation affects organizational commitment, interacts with supervision satisfaction, and has a moderating effect. Based on this, in order to improve the organizational commitment of social welfare public officials during public-private cooperation work, specific measures were proposed for sharing awareness and understanding between the public and private sectors, establishing an official system, and establishing a supervision system.

Competition of today's markets get to compete the relationship of one system and another system. Competition in relationship of system emphasis molding of cooperate relationship-strycture between enetrprices and It appears competitiveness enriched effects of enterprices in systems. In the rapidly changing economy and marketing situation, Travel agency got worse management situation of themselves more excessive competitiveness then competitiveness efforts between Tourism Relationship Enterprices. So, Relationship marketing will lays a foundation of new travel agency's environment through competitive of relation to travel agency and travel agency, travel agency and hotel or travel agency and airplane. This study's object are present relationships between travel agency and travel relation enterprise of cooperation, complication and competitiveness to relation form. And this study are presents suggestion to generate of hereafter travel relation enterprise through study on relationship with hotel and airplane. A final object of this study are presents a model applys relation method of travel agency and travel agency, hotel and airplane through inspect to specialist analysis. In the result of study, Travel agency are low position and difficult with hotel and airplane at the cooperation but acually It's difficult with travel relation enterprise. So, Travel agency will be operates characteritic system and regulations for win with travel relation enterprise for efficiency of working more than hotel and airplane. Airplane is the best big travel relation enterprise. So, The most airplane has to high cooperate with travel agency. That's why airplane keep going close cooperation with travel agency. Travel agency has to close cooperate with hotels secondly through marketing, exchanging information and union advertisement etc. Hotels are low in complications than travel agency but high in complications than airplane. Although travel relation enterprise are different system individually, because of all of us working with union object, Travel agency and travel compliment-cooperation relationship.relation enterprise has to autonomy behavior with close cooperation through.

본 논문에서는 협력통신을 위한 coded cooperation 시스템의 성능 분석을 기술한다. Coded cooperation은 user cooperation과 채널 부호의 결합된 프로토콜로서 기존의 coded cooperation의 연구는 주로 이동통신 환경을 고려한 Rayleigh fading 채널에서 이루어 졌다. 최근에 초고속 근거리 무선전송을 위한 60GHz 대역의 반송파를 이용한 연구가 활발해 지면서 Rician fading 채널 기반의 협력통신 분석에 대한 필요성이 제기되었다. 본 논문에서는 coded cooperation 시스템의 outage probability 성능과 bit error probability의 성능을 Rician fading 채널에서 분석하고 Rayleigh fading 채널에서와 같이 다이버시티 오더 값이 2로 유지됨을 보인다.
