  • Purpose: The purpose of this study was to determine the effects of the Traditional Play-centered Obesity Control Cooperative Learning Program based on the cooperative learning theory on obesity rate, physical fitness, self-esteem, and body image specifically in obese elementary school children. Methods: The research design for this study was based on a non- equivalent control group pretest-posttest design. The study was conducted from September, 5 to November 30, 2012. The subjects included 74 obese children ($Exp.=25^{(a)}$, $Com.=24^{(b)}$, $Cont.=25^{(c)}$) with an obesity rate above 20% at an elementary school in G City. Data analysis was performed using SPSS/WIN 18.0, using Chi-square test, one-way ANOVA, and Scheffe test. Results: The obesity rate (F=4.033, p<.022) in the experimental group was significantly lower than that in the group (Com, Cont), in which the Traditional Play-Centered Obesity Control Cooperative Learning Program was not implemented. Self-esteem (F=4.310, p<.017) also caused significant differences. However, physical fitness (Muscular endurance F=1.545, p=.220; Flexibility F=.671, p=.514; Agility F=1.594, p=.210; Speed F=5.386, p<.007, scheffe (a,b

  • This paper presents the real channel measurements and investigates their statistical characterization in wireless body area network(WBAN). In on-/off body channel, the measurements are performed with some representative human movements for considering human movements. Moreover, three signal transmission schemes with outage constraint are studied for getting total power consumption in each transmission scheme. Using the real channel measurements, between theoretical and realistic simulation are compared. This paper shows that power efficiency is improved through cooperative communication, and how much position of sensor node and human movement affect signal transmission power.

  • This paper deals with the problem of self-learning cooperative motion control for the pushing task of a humanoid robot in the sagittal plane. A model with 27 linked rigid bodies is developed to simulate the system dynamics. A simple genetic algorithm(SGA) is used to find the cooperative motion, which is to minimize the total energy consumption for the entire humanoid robot body. And the multi-layer neural network based on backpropagation(BP) is also constructed and applied to generalize parameters, which are obtained from the optimization procedure by SGA, in order to control the system.

  • Recently, there has been an increase in research on wireless sensor networks (WSNs) because they are easy to deploy in applications such as internet-of-things (IoT) and body area networks. However, WSNs have constraints in terms of power, quality-of-service (QoS), computation, and others. To overcome the power constraint issues, wireless energy harvesting has been introduced into WSNs, the application of which has been the focus of many studies. Additionally, to improve system performance in terms of achievable rate, cooperative networks are also being explored in WSNs. We present a review on current research in the area of energy harvesting in WSNs, specifically on the application of simultaneous wireless information and power transfer (SWIPT) in a cooperative sensor network. In addition, we discuss possible future extensions of SWIPT and cooperative networks in WSNs.

  • When a humanoid robot pushes an object with its force, it is essential to adequately control its posture so as to maximize the surplus torque far all joints. For such purpose, this study proposes a method to find an optimal posture of a humanoid robot using a genetic algorithm in such a way that the surplus torque for all joints is maximized. In this study, pushing motion of an 18-DOF humanoid robot is considered. When the robot takes a cooperative motion to push an object, the palms and soles are assumed to be fixed at the object and ground respectively, and are subjected to sense the reaction force from the object and the ground. Then, the torques for all joints are calculated and reflected to fitness function of the genetic algorithm. To verify the effectiveness of the proposed method, a number of simulations with different fitness functions are carried out. The simulation result shows that the proposed method can be adopted to find optimized posture in cooperative motion of a humanoid robot.

  • According to the 2012 social blue book released by the Chinese Academy of Social Sciences, China's urban population reached 50% in 2011. With the migration from marriage and new household registration, many urban collective assets have been formed in cities. Due to the unclear property rights and the emptiness of the main body, the distribution of collective assets mostly depends on the village cadres. The central government is preparing relevant laws and regulations to fill this legal gap, while the scheme of restructuring is decided by the villagers' vote, the local government coordinate the land acquisition and management. With the process of urbanization, a large number of second-generation of demolition studied abroad, which has attracted worldwide attention. In addition to the huge amount of compensation, due to the continuous rising of the land price, the value of the collective property and enterprises on the land also keep rising, the management agency of these assets is named village economic cooperative. This paper seeks to analyze the current status and future direction of these wealthy organizations, propose solutions to some existing problems.

  • This study suggests the necessity and domestic application plan a national authority database that promotes an integrated access, richer search, and understanding of historical information sources and archival resources distributed among cultural heritage institutions through the "Social Networks and Archive Context" project case. As the SNAC project was transformed into an international cooperative organization led by NARA, it was possible to secure a sustainable operating system and realize cooperative authority control. In addition, SNAC authority records have the characteristics of providing richer contextual information about life and history and social and intellectual network information compared to libraries. Through case analysis, First, like SNAC, a cooperative body led by the National Archives and having joint ownership of the National Library of Korea should lead the development and expand the scope of participating institutions. Second, in the cooperative method, take a structure in which divisions are made for each field with special strengths, but the main decision-making is made through the administrative team in which the two organizations participate. Third, development of scalable open source software that can collect technical information in various formats when constructing authority data, designing with the structure and elements of archival authority records, designing functions to control the quality of authority records, and building user-friendly interfaces and the need for a platform design reflecting content elements.

  • The dispute analysed in this article concern eight measures taken by Argentina regarding finance, taxation, foreign exchange, and registration. The dispute centered on whether these measures were in violation of the Member's obligations under the General Agreement on Trade in Services (GATS), namely most-favored national treatment, national treatment and market access, and whether they are justified by Article XIV and Article 2(a) of the Annex on Financial Services. Important arguments raised in the dispute include whether the services and the service providers of cooperative and non-cooperative countries and/or Argentina subjected to the measures are like for the purposes of Article II and Article XVII of the GATS, whether the regulatory aspects of the measures are to be considered in determining the inconsistency with Article II and Article XVII of the GATS, and whether the measures are justified in that they were taken in accordance with the national laws and regulations aimed at implementing the Global Forum on Transparency and Exchange of Information for Tax Purposes and the Financial Action Task Force. The essence of this dispute lies in the balance of each Member's right to regulate commercial and/or financial activities and its obligations under the GATS. The Appellate Body tried to strike such a balance in its assessment of: (i) likeness of services and service suppliers, (ii) no less favorable treatment under Articles II and XVII, and (iii) the scope of measures under Article 2(a) of the Annex on Financial Services. This article aims to provide an analysis of the Appellate Body's findings, giving light to the relevant jurisprudence and scholars' writings.
