The purpose of this study is to verify the effects of team trust and cooperative behavior on the food-service employees' perceived service performance as well as the moderating effects of team competency and other department support in the relationship among the team trust, cooperative behavior, and service performance of food-service employees. We conducted a survey of 1,080 food-service employees working in 8 hotels and 4 food-service stores located in Seoul, Gyeonggi, Song-do, Gyeongju, and Busan, and 841 food-service employees were employed for statistical analysis except unreliable responses. As a result of a SEM (structural equation modeling) analysis to confirm hypotheses, it was found that team trust (leader trust and co-worker trust) had a positive effect on the cooperative behavior. In addition, the cooperative behavior had a positive influence on the food-service employees' perceived service performance. Also found was the moderating effect of other department support in the relationship between the cooperative behavior and food-service employees' perceived service performance. Based on the research findings, we discussed its academic and practical implications, and suggestions on the future research.

There is much selective confliction in nature where selfish and rational individuals exists. Iterated Prisoner's Dilemma (IPD) game deals with this problem, and has been used to study on the evolution of cooperation in social, economic and biological systems. So far, there has been much work about the relationship of the number of players and cooperation, strategy learning as a machine learning and the effect of payoff functions to cooperation. In this paper, We attempt to investigate the cooperative coalition size according to payoff functions, and observe the relationship of localization and the evolution of cooperation in NIPD (N-player IPD) game. Experimental results indicate that cooperative coalition size increases as the gradient of the payoff function for cooperation becomes steeper than that of defector's payoff function, or as the minimum coalition size gets smaller, Moreover, the smaller the neighborhood of interaction is, the higher the cooperative coalition emerges through the evolution of population.

Over the last few years, despite the government's ongoing efforts for cooperative relationship between large firms and small and medium-sized enterprises(SMEs), their effectiveness is limited. In addition, the academic researches for addressing practical policy alternatives are also insufficient. This study aims to suggest the practical policies for cooperative relationship between large firms and SMEs. To this end, we suggest typology to know how collaboration process between large firms and SMEs for technology commercialization project with the utilization of dimensions of technology and marketing cooperaton is, and analyse the characteristics of each type, and examine the present situation of collaboration between large firms and SMEs in Korea and then finally, derive government policy guidelines. Through this research, we suggest theoretical framework to reinforce national industry competitiveness under growing global competition through suggesting how SMEs take survival basis, and also how large firms collaborate with SMEs.

Purpose: The purpose of this study was to investigate factors affecting turnover intention in pediatric nurses. Methods: A survey was conducted with 212 nurses working in pediatric units at 15 hospitals in Busan, K city. Data were collected from September 1 to October 31, 2014. and analyzed with SPSS PASW 18.0. Results: In Stepwise multiple regression analysis, factors affecting the nurses' turnover intention were emotional burnout (${\beta}$ =.37, p<.001), relationship between nurse and doctor (${\beta}$ =.20, p<.001), turnover plan (${\beta}$ =.17, p<.001), and annual salary (${\beta}$ =-.13, p<.001), and these variables accounted for 32.2% of the variance in turnover intention. Conclusion: The findings indicate that the major factors influencing pediatric nurses' turnover intention are emotional burnout, cooperative relationship between nurse and doctor, turnover plan, and annual salary. Thus, in order to reduce pediatric nurses' turnover intention, it is necessary to develop intervention programs to prevent emotional burnout, the most influencing factor, and enhance cooperative relationship between nurse and doctor and to examine their effects.

The study examines the relationship between co-operative society governance and members' satisfaction. Co-operative societies face problems of how to keep balance between efficiency and governance because those in charge of operations of co-operative; the board and the staff must meet two demands i.e. good business practice and the social responsibility which involves the satisfaction of members. The objective of this study is to examine the relationship between co-operative governance and members' satisfaction using Ambrose Alli University Workers/Farmers Multi -Purpose the Co-operative Society as a case study. The data collected in this study were obtained through structured questionnaire. Data analyzed were subjected to descriptive statistics and graphs. The data analyzed indicated that the challenges facing the co-operative society include theft /fraud and mismanagement. Members agitated for transformation of the co-operative society to operate in line with the guidelines of the Central Bank of Nigeria. It was recommended that for efficiency and high productivity, staff should be trained. Also there is need for innovative technology and the necessity for the cooperative society in question to network with other organizations.

In this paper, the capacity criteria have been proposed in order to select a cooperative relay node in WSNs, under the environment where direct path has a poor link gain. This process may ensure the efficiency improvement of signal transfer between source and destination and reduction of energy consumption as well. Two criteria are incorporated to select a cooperative relay node. Firstly, calculate the energy gain ratio between the relay path and the direct path. Secondly, investigate the effects of relay node's usage in WSNs through the simulation in terms of energy consumption. In the simulation, the relationship between energy consumption and direct path gain, uniformly generated in the certain range and its positive effects have been identified.

Purpose - This study aims to examine whether key differences in characteristics of unions have significant implications for absenteeism. To uncover what characteristics of union made workers make decisions to be absent, this study used such key dimensions of unionism as democracy, cooperative strategy of a union, and d density rate. Research design and methodology - The research model of this study is that absenteeism has positive relations with union's democracy and density. But it has negative relations with union cooperative strategy. This study was conducted by survey method on 333local unionized business entities of metal industry in South Korea. Results - The result shows that significant and positive relationship between unions with high density rates, democracy and absenteeism which is in line with the argument of the previous studies. Different from the expectation, the hypotheses 2, it has been shown that there is positive relation between cooperative strategy of union and the decision of workers to be absent. Conclusions - Employers with unions with high density rates could not fully exercise disciplinary power against those workers absent at workplace since a strong union shields them effectively from punishments by employers.

In this paper, we proposed a contract theory based cooperative spectrum sharing scheme with joint power and bandwidth optimization under asymmetric information, where the primary user (PU) does not know the secondary users' (SUs) private information. To improve performance, PU needs to provide incentives to stimulate nearby SUs to help forward its signal. By using contract theory, PU and SUs' negotiations are modeled as a labor market. PU and SUs act as the employer and employees, respectively. Specifically, SUs provide labor (i.e. the relay power, which can be used for forwarding PU's signal) in exchange for the reward (i.e. the spectrum access bandwidth which can be used for transmitting their own signals). PU needs to overcome a challenge how to balance the relationship between contributions and incentives for the SUs. We study the optimal contract design which consists of relay power and spectrum access bandwidth allocation. We show that the most efficient SUs will be hired by the PU to attend the cooperative communication. PU can achieve the same maximum utility as in the symmetric information scenario. Simulation results confirm that the utility of PU is significantly enhanced with our proposed cooperative spectrum sharing scheme.

Mentoring is defined as a sustained relationship between a mentor and a mentee. Through continued involvement, the mentor offers support, guidance, and assistance as the mentee faces new challenges, or works to correct earlier problems. A mentoring for cooperative learning has many merits including higher order thinking, collaborative competencies, socialization and development. In this paper, a U(Ubiquitous)-CoMM(Community of mentor & mentee) system was supposed to design an instructional learning strategy using cyber community of mentor & mentee in a ubiquitous environment. The proposed system provides participants with campus mentoring program in which they share their experience and expertise. By experimental result showed that the proposed system is effect in education about cooperative learning than existing system.

The purpose of the present study is to examine the effect of civic cooperation with the police on the number of crime that the police must solve by conducting simulation based on system dynamics. The study sets police oriented-policing model and police-citizen cooperative model to investigate the effect of civic cooperation with the police. As a result of the simulation, the police oriented-policing model shows that the number of crime that police must solve is increasing over time, while the police-citizen cooperative model shows that the number of crime that must be solved by the police is keeping it stable in the increase of crimes. Comparing both models, civic cooperation with the police is more effective in reducing or deterring crime than police oriented-policing activity. The study proves that building cooperative relationship between citizens and the police can become a strategic method for controlling crime effectively without a rapid increase in police finance. It is meaningful in terms of presenting a dynamic change of interaction for reducing crimes between civic cooperation with the police and policing activity of the police over time.
