The purpose of this study was to developing a cooperative learning model utilize storytelling technique to the Preliminary childhood teachers whose learning was in order to improve ability and collaboration of making relationships a teams members by the cooperative learning which was performed on the basis of the confidence after understanding themselves and others. To achieve the purpose, the study was performed by dividing into two stages. First, the draft of storytelling based cooperative learning model was proposed by performing a literature survey and a case study. Second, the draft model was applied to the actual work. And the draft was modified and developed to the final model on the basis of the draft model's strenth and implemented to 39 students who were the sophomore of child care education department and enrolled the profession class of at B college P city for 8 weeks. From the implementation result of the model, it was obtained that there was the positive reaction on applying storytelling technique to the beginning stage of cooperative learning. And adding of 'Re-constitution role sharing team' step in the original steps was suggested. In the end, this model was modified and issued based on the research result. The researchers proposed a cooperative learning model storytelling based for Preliminary childhood teachers which consists 6 phases : (1) understanding cooperative learning (2) Building the team and role sharing team (3) theme setting and theme structuralization (4) Re-constitution role sharing team (5) announcement of the results and evaluating (6) reflection of general.

Objectives : The aim of this study is to give a statistical basis for the characteristics of patients who received cooperative medical care after being referred from Western medical departments to the Department of Acupuncture and Moxibustion in a Korean medical hospital. Methods : The request records were searched for cooperative medical treatment at the Department of Acupuncture and Moxibustion in a Korean medical hospital between September 1st, 2011 and August 31, 2016, based on the Order Communication system(OCS). The records were reviewed and retrospectively analyzed according to the patient's general characteristics, the chief diagnosis code based on the 7th Korean standard classification of diseases(KCD-7) before and after the cooperative medical care in the Department of Acupuncture and Moxibustion, and the actual treatment measures which patients received as a result of the cooperative medical care. Results : Among the 2702 records, 1549 patients were included in the analysis. The male to female ratio was 1 : 1.17. Sexagenarians formed the highest age group and the number of patients whose age was over 50 was 1176(75.92 %). The surgery department requested the cooperative care from the department of Acupuncture and Moxibustion for the highest number of patients, 1194(77.08 %). When analysing specific medical departments, Neurosurgery, General Surgery, Neurology, Otorhinolaryngology, and Physical medicine and rehabilitation followed. The frequency of chief diagnosis code used before the cooperative medical care was in the order of I, C, G, S, and M code, from highest to lowest. The order of the codes after the cooperative medical care was the same. Acupuncture treatment was the most frequently-used measure after the cooperative medical care. Following were infrared, moxibustion, transfer, herbal acupuncture, cupping, electroacupuncture, and so on. Conclusion : This study provides a statistical basis for the demands placed on the Department of Acupunture and Moxibustion for cooperative medical care with the Western medical department. Based on the present condition of cooperative medical care, more preparation and effort is required for its activation.

Recently, one of the issues to be discussed from the viewpoint of product management in National R&D Programs is about the management of intellectual property produced by joint research and development. According to existing legislative system, the main R&D institute and collaborative enterprise own the patent produced by joint R&D activities together at the rate of investment. But, there are many discussions if that is right in legal principles and in substance. Patents by Cooperative National R&D Programs are very different from common patents because of its characteristics and have scheme controlled complexly by related laws and ordinances. This paper aims to review the legal theory on the possession and utilization of patents produced by Cooperative National R&D Programs, and to try to find out the improvement of existing legislative system. For this purpose, after looking into the meaning and the legal system of Cooperative National R&D Programs, and examining the ruling theory on the possession and utilization of co-invented patent, finally research the problems and improvement of existing related legislative system.

This paper investigates linear soft combination schemes for cooperative spectrum sensing in cognitive radio networks. We propose two weight-setting strategies under different basic optimality criteria to improve the overall sensing performance in the network. The corresponding optimal weights are derived, which are determined by the noise power levels and the received primary user signal energies of multiple cooperative secondary users in the network. However, to obtain the instantaneous measurement of these noise power levels and primary user signal energies with high accuracy is extremely challenging. It can even be infeasible in practical implementations under a low signal-to-noise ratio regime. We therefore propose reference data matrices to scavenge the indispensable information of primary user signal energies and noise power levels for setting the proposed combining weights adaptively by keeping records of the most recent spectrum observations. Analyses and simulation results demonstrate that the proposed linear soft combination schemes outperform the conventional maximal ratio combination and equal gain combination schemes and yield significant performance improvements in spectrum sensing.

In this paper, performance of cooperative communication system is analyzed with various relay conditions for mobile communication system using OFDM. We research mainly on the performance analysis of amplify-and-forward scheme. First, we analyzed the diversity gain between the number of antenna on the relay is one and two. And then, in this paper, we analyzed difference of the performance with distance between relay and mobile. Amplify-and-forward scheme has the problem that the noise components are also amplified in low sinal-to-noise (SNR) condition. The results of this paper can be applicable to the cooperative relay systems.

This letter considers the problem of resource sharing among a relay and multiple user nodes in cooperative transmission networks. We formulate this problem as a sellers' market competition and use a noncooperative game to jointly consider the benefits of the relay and the users. We also develop a distributed algorithm to search the Nash equilibrium, the solution of the game. The convergence of the proposed algorithm is analyzed. Simulation results demonstrate that the proposed game can stimulate cooperative diversity among the selfish user nodes and coordinate resource allocation among the user nodes effectively.
