We consider a system where a licensed radio spectrum is shared by multiple primary users(PUs) and secondary users(SUs). As the spectrum of interest is licensed to primary network, power and channel allocation must be carried out within the cognitive radio network so that no excessive interference is caused to PUs. For this system, we study the joint beamforming and power allocation problem via game theory in this paper. The problem is formulated as a non-cooperative beamforming and power allocation game, subject to the interference constraints of PUs as well as the peak transmission power constraints of SUs. We design a joint beamforming and power allocation algorithm for maximizing the total throughput of SUs, which is implemented by alternating iteration of minimum mean square error based decision feedback beamforming and a best response based iterative power allocation algorithm. Simulation results show that the algorithm has better performance than an existing algorithm and can converge to a locally optimal sum utility.

The rapid industrial and technological development has made the human activities for the utilization of marine resources more complex. Marine spatial management is a space-based approach. It is a comprehensive and integrated management approach. The ultimate goal of marine spatial management is the "sustainable use" of marine resources. The partial approach is applied in the existing marine spatial management, mainly coastal zones which involves integrated approach. Also this showed various limitations including restricted mostly to coastal zones, and limitation to implementation tools. However, for marine spatial management to have a reasonable approach that attaches importance to the relationship between humans and the holistic ecosystem, it is important to internalize a central principle in marine spatial management that focuses on the sustainable use of marine resources. In the present study, four central principles are proposed that will eventually be applied through marine spatial management planning tools. These principles are 1) the establishment of a cooperative decision making and planning system that is based on stakeholder participation; 2) scientific assessment of the current status and impact on the basis of ecology, sociology, and economics; 3) reasonable and optimal spatial assignment based on the forecasting of future-use characteristics and environmental changes; and 4) ascribing importance to the implementation of the results of rational planning processes.

Numerous solution methods for scheduling problems such as part dispatching problem, operation sequence problem have been suggested as a means to be embedded in hierarchical or centralized shop floor control. Under the preceding control philosophies, however, response to changes in the shop floor status is quite slow and timely decision is sometimes impossible. Moreover, the control software becomes too large and it is almost impossible to modify the control software when the configuration of the shop floor changes. In agile manufacturing which emerged recently to cope with quick response and easy modifiability when unexpected changes occur, a new control policy is needed. CSCW[Computer Supported Cooperative Work] based shop floor control casts a different view on scheduling problems. Decisions are made locally when requested and useful information is scattered among agents for its efficient use. Adaptation is easy because agents are -'plug compatible or portable. In this paper, scheduling problems occurring under CSCW based shop floor control are identified and characterized. Traditional scheduling problems are reviewed from the CSCW viewpoint. All the control entities involved in the shop floor can be found and used to defined agents. With these entities and CSCW concept, possible scheduling problems are identified.

Purpose: This study examines the impact of individual reciprocal preferences on coalition formation. The reciprocal model considers a player's own payoff, the player's perception of others' payoffs, and others' perceptions of the player's payoff. Research design, data and methodology: A reciprocal model is built to illustrate how reciprocity influences individual decisions in a coalition game and its formation. The prediction is examined with experimental evidences from a dictator game and a membership game. Results: The theoretical result suggests that the coalition formation could be unstable due to negative reciprocal kindness. The experimental findings support that negative reciprocal kindness could lead players participating in a coalition, no matter their dominant strategies are. When subjects were essential to make contributions to a coalition, they were more likely to cooperate if they were treated badly. In contrast, when subjects were unnecessary, the reciprocal kindness could enhance cooperative tendencies. Conclusions: This study reveals that the reciprocal behavior could influence individual decisions and reshape the coalition formation. In terms of policy implications, this study has shown that coalition formation could be reshaped by reciprocal prefe rences. Due to the strategic and complicated decision process in an interactive environment, a comprehensive investigation of factors would be required in a climate coalition in practice.

A sruvey was conducted to investigate the consumer perception of farm products and processed foods, and to figure out the future direction of food supply system to satisfy the consumer need. From the citizens in Taegu area, 532 housewives were selected as sample subjects by stratified random sam-pling procedure. The main criteria of consumers for purchasing farm products was quality and the main reason for purchasing imported products was cheap price(48.9%). Most of consumers(87%) thought that food safety of farm products was not belong to safe level. Consumers(79.7%) perceived that the labeling system for the place of origin and for the quality are necessary, but they did not have confidence in the current label. Nearly all the subjects(93.6%) were concerned about the hazardness of residual chemicals of imported products, desired the rigorous inspection system for imported products. Consumers in Taegu area had confidence in processed foods in the following order; farmerbrand-product(0.9%), government-authorized farm product(30.0%) and agricultural cooperative association product(26.4%). However, only 73.6% of the consumers had the experience to purchase farmers' processed foods. As a conclusion, it appeared that nutrition education for consumers on food-decision making is strongly required for the substantial segment of population who are still ignorant of safety of imported product and food distribution system.

최근 잦은 교통사고로 인하여 발생하는 사상자의 수를 줄이고 운전자의 편의를 제공하는 지능형 교통 시스템(intelligent transportation system, ITS)이 주목받고 있다. ITS는 긴급 상황에 신속하게 대처할 수 있어야 하며, 운전자가 필요로 하는 정보를 즉시 제공하여야 한다. 효과적인 서비스를 위하여 ITS에서는 각 서비스별로 다른 채널을 할당한다. 그러나 긴급 상황에서 채널을 사용하려 할 때 채널이 사용 중이라면 서비스가 불가능한 상황이 발생한다. 이를 해결하기 위해 본 논문에서는 지능형 교통 시스템에 인지 무선(cognitive radio, CR)개념을 도입하고 새로운 스펙트럼 센싱 기법을 제안한다.
