Purpose - Domestic cooperatives tend to increase during the establishment of cooperatives and gradually through the basic law of social needs. However, only cooperatives' qualitative grow this secured without blessings, and their quantitative growth through government support is questionable. The purpose of this study is to analyze the agricultural cooperatives established through the Distribution System Cooperatives Basic Law, which was enacted in January 2012. Subsequently, establishing agricultural cooperatives was done briskly. However, cooperatives established rapidly after the founding of the Basic Law encountered problems. Research design, data, and methodology - To assess the performance of selected agricultural cooperatives, data were analyzed using the methodological Analytic Hierarchy Process (AHP) approach. The AHP is a set of systematic procedures to hierarchically analyze the elements of any problem. Using a survey on expertise, a series of comparative determinations of each pair is performed to evaluate the relative strengths and the strengths of the impact between elements within the hierarchy. A survey was conducted on 10 small agricultural cooperatives using AHP analysis for the examination. The purpose of such research and analysis is to recommend a direction for future policies aimed at small agricultural cooperatives. Result - This study applied three types of policy evaluation criterion, including market expansions, organizations, and cooperative projects, and 12 types of small agricultural cooperative policy measures. Market expansion policies for agricultural cooperatives are classified into four categories: school meals, direct transactions, shopping malls, and wholesale markets. Organizational policies for agricultural cooperatives are classified into four types: existing sales channel management, education, preventing free riding, and enlarging members. Cooperative project policies in agricultural cooperatives are classified into four policy areas: cooperation between cooperatives, community contribution, joint businesses, and government links. In this paper, the growth priority in agricultural cooperative policies is analyzed by applying policy evaluation criteria on the basis of a survey on expertise. The priorities of the policy program are also analyzed using a decision analytic hierarchy process. The results indicate that market expansion is the most important policy evaluation criterion therefore, improving direct transactions, school meals, management of existing sales channels, and shopping malls are crucial policy measures. In contrast, the cooperation of cooperatives, expansion of union members, and cooperation with the government were found to have low priority. Conclusions - Agricultural cooperatives should develop plans as follows. Small agricultural cooperatives need to secure school meals and direct transactions for market expansion, restructure marketing strategies to manage existing sales channels, and, finally, increase education and training for sustainable organizational development. This study has the following limitations. Because the subject of the investigation is a new cooperative, determining its sustainable growth is difficult. Therefore, through analysis and a continuous study of cooperatives, future research is expected to show that modifying the direction of agriculture cooperatives is necessary.

지리산국립공원은 1967년 12월 29일 우리나라 최초로 국립공원으로 지정되었으며, 지정 후 수반되는 행위규제로 인해 주민들의 재산권 침해와 후대에 물려 줄 유산적 가치로서의 자연보전과의 끊임없는 갈등을 빚고 있다. 따라서 본 연구의 목적은 이러한 갈등상황을 해결할 수 있는 합리성에 근거를 둔 의사결정 대안을 찾는 데 있다. 이를 위해 지리산국립공원을 둘러싼 이해주체들의 갈등해결을 위해 합리적 의사결정을 지원할 수 있는 게임이론을 적용하였고 게임의 구성요소는 경기자인 지리산국립공원과 마을주민, 산림의 이용과 보전에 대한 각 이해주체들의 전략, 그리고 전략에 따른 보수 등을 바탕으로 비협조적 게임으로 분석한 결과 나타난 내쉬균형은 서로의 이익을 추구하며 갈등이 깊어지는 것으로 나타났다. 그러나 이해주체들이 인정할 수 있는 공리를 포함한 전략과 그에 따른 보수를 바탕으로 한 협조적 게임의 결과는 비협조적 게임의 내쉬균형이 가지는 보수보다는 작을 수 있으나 서로 Win-Win할 수 있는 전략집합을 이루며 갈등이 해결되는 양상으로 나타났다. 하지만 사람의 합리성으로 인해 불확실성이 발생되기 때문에 이해주체가 인정할 수 있는 공리와 그것을 지켜갈 수 있는 신뢰가 확보된다면 우리나라 국립공원이 겪고 있는 구조적 갈등을 해결할 수 있는 하나의 방법이 될 것으로 사료된다.

Mibyeong health service consists of diagnosis with nine constitutional type, health guide and preventive treatment. Community health center also provide Mibyeong health service, with cooperative treatment of traditional Chinese medicine and western medicine. China's Mibyeong health policy is established by Top-down decision, even though there is not enough evidence for providing health service to consumer. Through constitutional diagnosis, examinations, and treatment, huge data have been stacked; however, assessment and research based on these data are not processed well. Cooperative treatment of traditional Chinese medicine and western medicine is widely provided to patients, and their works are relatively well classified. Conclusions : China plays leading role in Mibyeong service and it seems to be developed more than Korea's. Further study is necessary to establish Mibyeong policy and health service in Korea.

Single-user spectrum sensing is susceptible to multipath effects, shadow effects, hidden terminals and other unfavorable factors, leading to misjudgment of perceived results. In order to increase the detection accuracy and reduce spectrum sensing cost, we propose an adaptive cooperative sensing strategy based on an estimated signal-to-noise ratio (SNR). Which can adaptive select different sensing strategy during the local sensing phase. When the estimated SNR is higher than the selection threshold, adaptive double threshold energy detector (ED) is implemented, otherwise cyclostationary feature detector is performed. Due to the fact that only a better sensing strategy is implemented in a period, the detection accuracy is improved under the condition of low SNR with low complexity. The local sensing node transmits the perceived results through the control channel to the fusion center (FC), and uses voting rule to make the hard decision. Thus the transmission bandwidth is effectively saved. Simulation results show that the proposed scheme can effectively improve the system detection probability, shorten the average sensing time, and has better robustness without largely increasing the costs of sensing system.

This study applies diverse game theories to the US-China Trade War. The US-China Trade War can be analyzed as a game situation because the strategic decision-making process to maximize one's profit while considering the reaction of the other party is a game situation. However, related research suffered from some mistakes in applying the US-China Trade War as it is to classic game theory, because while the prisoners dilemma is based on the situation of No Communication, No Trust, No Cooperation, the US-China Trade War has a precondition different from that of prisoners dilemma, since it mutually communicates information and negotiation is repeated several times in a cooperative situation. The result of the trade negotiation will likely end as 'cooperate-cooperate'. Further, considering trade volume, trade interdependence, bargaining power based on economy, and the scale of damage caused by the Trade War, the US-China Trade War is progressing with the bargaining power of the US being higher than that of China. Since the current US-China Trade War is in an asymmetrical situation under the dominant bargaining power of the US, it is likely to reach 'US defect-China cooperative' in the long run.

In this paper, we propose a method for diagnosing overload and working load of collaborative robots through performance analysis of machine learning algorithms. To this end, an experiment was conducted to perform pick & place operation while changing the payload weight of a cooperative robot with a payload capacity of 10 kg. In this experiment, motor torque, position, and speed data generated from the robot controller were collected, and as a result of t-test and f-test, different characteristics were found for each weight based on a payload of 10 kg. In addition, to predict overload and working load from the collected data, machine learning algorithms such as Neural Network, Decision Tree, Random Forest, and Gradient Boosting models were used for experiments. As a result of the experiment, the neural network with more than 99.6% of explanatory power showed the best performance in prediction and classification. The practical contribution of the proposed study is that it suggests a method to collect data required for analysis from the robot without attaching additional sensors to the collaborative robot and the usefulness of a machine learning algorithm for diagnosing robot overload and working load.
