Recently, at Home and abroad, Internet of Things era things(Thing) is participating as a subject of communication in human communication paradigm of existing (lot/M2M) is in full swing. Automobile, refrigerator, bicycle, until shoes, and communication functions generation of information is installed and has created a fusion of new service IT infrastructure. Its use and application are broadening to various areas and the number of devices used for it is increasing to increase the number of information transmitted for each object. When the traffic reaches its limit while each set of data is transmitted from the devices divided into each group through the mobile network, M2M communications service might not be processed smoothly. This study used the Knapsack Problem algorithm to create a virtual simulator for a smooth M2M service when the mobile network used for the M2M communications reaches its limit. The virtual simulator applies smooth processing of services from the M2M communications that should be processed first to other subsequent services when data comes to each group of devices. As the M2M technology develops to make many objects more compact in size, it would help with smoother processing of M2M services for the mobile network with fast-increasing traffic.

In this paper, we propose a new paradigm of augmented reality board game environment and a portable game assistant(PGA) which can help gamers with strategy information. Previous AR board games consist of a private and public space. The public space provides rules of the game and shows the scene of game. And the gamers control game pieces in the public space. The previous games use the RFIDs for recognizing positions of the pieces, and the VR/AR environment for providing the scene of the game. However the RFIDs are expansive, and the VR/AR environment is inconvenient because it uses additional devices: the DataGlove, the digital pen, and the HMD. The proposed system recognizes positions of real pieces using the computer vision technique, and uses a monitor to provide dynamic effects. In the private space, previous systems provide entire screen of game and position of specific pieces, but cannot be controled the pieces by gamers. Therefore, in this system, we provide PGA that helps the user to plan of the strategy individually using universally mobile. The PGA helps to plan the strategy in the individual area, and to play easily in the side of the user's convenience.

This study examined the correlation between the forward head posture (FHP), temporomandibular joint disorder (TMD), and temporomandibular joint quantitative somatosensory sensation. This study examined the correlation between the temporomandibular joint function and somatosensory sensation according to the change in FHP after the intervention on the head posture in 62 subjects (22.15 ± 2.56 years) Biofeedback training was administered to the FHP, which was performed 12 times for a total of four weeks. To assess the FHP, the craneovertebral angle (CVA) was examined. The temporomandibular joint (TMJ) function was measured by the Therapeutic Range of Motion Scale and the left and right lateral deviation, and the sensation of vibration threshold was measured to confirm the change in somatic sensation. Multiple regression analysis was performed to confirm the influence of each variable and Pearson's correlation analysis was performed to assess the correlation. Changes in the temporal joint function (p<.001) and somatic sensation (p<.001) were correlated significantly with the changes in CVA. These results show that there is a significant correlation between the frontal head position, TMJ function, and somatosensory sensation. These results provide a new paradigm for the treatment of jaw joints for patients suffering from TMD and provide a basis for the future treatment of the temporomandibular joint.

Recently not only industry but also academy have shown an intense interest in social networking service. However, reckless imitation will not guarantee the successful eco-system of social networking service without rich understanding of growth driver and business model. Hence, this study aims at analyzing open platform strategy and business model conducted by a representative social networking service provider in order to provide platform operator, network operator, and portal provider with meaningful implications. Advertisers may pay great attention to social networking service because it has strong ability to provide users with spontaneous motivation to manage and update their profile, and these valuable information can be utilized for providing personalized advertisement on social networking service. As a result, one side of consumers in two side market, advertisers, tend to pay more expenditure to place advertisements. In addition, the open platform adopted by social networking service providers causes pro-sumers to participate in the eco-system, and thereby the explosive quantitative growth is realized. The fact of that this open social networking service can invade other web service area via an unified platform indicates that it may expand its service scope into a wide variety of web service areas. Hence, domestic portal services providers and network providers should consider social networking service not as one of new web services but as an disruptive service platform. Corresponding to the emergence of social networking service, especially if their business area is related to display advertising market, they should seek a way to provide social networking service access users's newly updated information and develop innovative media technologies to enter context awareness ads market.

Based on the operating system of the advanced school athletic clubs operated to attempt a new paradigm of athletic culture in the field of school athletics, this study aimed to conduct an in-depth analysis of the student athletes' academic level and seek a solution for the stream of the times and integrated change based on a relative minimum academic achievement standard applied by this system. For Analyzing the difference in academic grades between subjects to which the minimum academic achievement standard by the event is applied, one-way ANOVA and MANOVA were used. First, the grade point average (GPA) of the student athletes by the event did not reach the GPA of most general students. Second, it was predicted that in applying a standard, relative to the general students, as academic grades increased, the probability in which the student athletes do not reach the minimum academic achievement standard would increase. Third, it turned out that, even in the phased application of the current minimum academic achievement standard to the GPA of the student athletes by the event, the ratio of the attainment of the minimum academic achievement was similar.
