Objectives : The purpose of this study was to examine the results of the 2013 students' mental health school-community cooperative model. This study investigated teachers' awareness of change in school environment and analyzed the follow-up conditions of students. Methods : The sample consisted of 55 schools which participated in the 2013 students' mental health school-community cooperative model. Two questionnaires were used : one was composed of items about mental health resources, school policy and practice, school climate and community referral, and the other was on management of follow-up conditions for high risk students. Results : First, teachers' awareness regarding school mental health resources, school policy and practice, school climate, and community referral showed positive change. That is, the 2013 students' mental health school-community cooperative model works for improving teachers' interest, awareness and effort regarding mental health. Second, students, who were found by screening test and observation, were managed continually. Most students received follow-up interventions at school, and half of the students were referred to a specialized institution such as a mental health clinic, Wee center, personal counseling center, community welfare center, and so on. Conclusion : This study was a preliminary research, therefore follow-up studies are required in order to accomplish the 2013 students' mental health school-community cooperative model.

In this study, the purpose of the research is to present a cooperative convergence education Capstone design operational model that can promote community relations by spreading excellent practices through governmental, academic, and civil cooperation, ultimately contributing to the development of systematic plans among cooperative groups for successful promotion, and the production high effects in the fashion sector. The case study presented a new model that combines convergence in interdisciplinary studies, focusing on the case study of the "Fashion Capstone Design" textbook. The characteristics of the proposed model suggested three types of convergence- the convergence of government, academia and private cooperation, and the convergence of academic and civil organizations, depending on their role. The proposed educational model has the advantage of complementing and dealing with the difficulties presented by interdisciplinary education. It also has the effect of activating community linkages with colleges in the community. In addition, the effectiveness of community colleges and community links can be optimized. Through the example of this study, we look forward to being used as a references for a variety of cooperative convergence education capstone design projects.

We propose a novel cooperative guidance law design method based on the finite time disturbance observer (FTDO) for multiple near space interceptors (NSIs) with impact time control. Initially, we construct a cooperative guidance model with head pursuit, and employ the FTDO to estimate the system disturbance caused by target maneuvering. We subsequently separate the cooperative guidance process into two stages, and develop the normal acceleration command based on the super-twisting algorithm (STA) and disturbance estimated value, to ensure the convergence of the relative distance. Then, we also design the acceleration command along the line-of-sight (LOS), based on the nonsingular fast terminal sliding mode (NFTSM) control, to ensure that all the NSIs simultaneously hit the target. Furthermore, we prove the stability of the closed-loop guidance system, based on the Lyapunov theory. Finally, our simulation results of a three-to-one interception scenario show that the proposed cooperative guidance scheme makes all the NSIs hit the target at the same time.

Most work on cooperative diversity has assumed that the cooperating group (source and partners) and the associated average channel conditions between terminals (source, partners, and destination) are predetermined. In practical situations, however, it is important to develop the efficient algorithms for assigning the terminals with good inter-user channels for cooperating groups. In this paper, we propose the partner assignment algorithm for cooperative diversity in mobile communication systems. The proposed partner assignment algorithm is investigated by using the path loss model for mobile communication systems. Numerical results show that the proposed partner assignment algorithm provides the comparable probability of cooperative transmission to the partner assignment algorithm using exhaustive search. The probability of cooperative transmission increases with the number of users, which gives potential benefits of practical implementation to user cooperation in mobile communication systems.

The significance of this study was to analyze the quality value of organic livestock pork for the first time based on the results of managing and testing the cycling organic farming of black pork and vegetables within farm for two years. The results of analysis could be summarized as follows. First, the pork of experimental group with crop-livestock cycling farming showed the excellent quality and high consumer preference compared to the control group of general pork or pork from non-crop-livestock cycling organic farming. In the content ratio of Omega-3 as a representative essential fatty acid, it was 1.46 that was about 2.8 times more than general pork (0.52). In case of Omega-6, it had about 2.5 times more than general pork. Especially, the U/S ratio value which was the content ratio of Unsaturated Fatty Acid (UFA, U) of Saturated Fatty Acid (SFA, S), was largely shown in pork (2.93) from cycling organic farming. Second, it would be necessary to maintain the economies of scope shown in crop-livestock cycling organic farming, and the high quality value of livestock products. For this, there should be a value chain model that could realize the economies of scope and economies of scale at the same time based on scaling and diversification through cooperative organization between farmers. Through this, it would be possible to establish a cycling model called 'community cooperative agriculture' by forming local internal markets through cooperation of production-processing and integration of distribution-sale-consumption. For the managerial activation of this cooperative organization, the government should promote/support the small crop-livestock cycling organic farming cooperative organization in local unit. For securing the reliability of crop-livestock cycling organic agricultural products and crop-livestock cycling organic livestock products, it would be necessary to review the introduction of Participatory Guarantee System (PGS).

The model applied in this paper is based on the theory of economic order quantity (EOQ). EOQ model is introduced to explain the improvement of the transaction efficiency through the cooperative purchase. We examine explicitly how horizontal cooperation affects vertical transactions. A result of the analysis is that a seller can prefer transacting with a cooperative rather than with each buyer separately, even if he reduces the selling price of the product. Without increasing the demand for the product, this result is that dealing with a cooperative, rather than separately with each buyer, decreases the transaction cost for the seller-buyers system, the cost reduction more than off-setting the effect of price decrease on the sellers profit. For a coopative consisting of any number of buyers, Pareto efficient ordering policies that maximize the joint cost saving for the seller-buyers system are identified. We then discuss the conditions under which a cooperative under consideration can be modified to increase efficiency gain. Next, we relax the assumption that all buyers participate in a single cooperative and examine the issue of how many cooperatives, each consisting of a subset of the buyers, should be formed to maximize the total cost saving for the seller-buyers system. Finally, the issue of shapley value to divide the cooperatives gain among its members is discussed.
