To simulate solid dynamics,a we must com-pute the mass, the center of mass, and the products of inertia about the axes of the body of interest. These mass property computations must be continuously re-peated for certain simulations with rigid bodies or as the shape of the body changes. We introduce a GPU-friendly algorithm to approximate the mass properties for an arbitrarily shaped body. Our algorithm converts the necessary volume integrals into surface integrals on a projected plane. It then maps the plane into a frame-buffer in order to perform the surface integrals rapidly on the GPU. To deal with non-convex shapes, we use a depth-peeling algorithm. Our approach is image-based; hence, it is not restricted by the mathematical or geometric representation of the body, which means that it can efficiently compute the mass properties of any object that can be rendered on the graphics hardware. We compare the speed and accuracy of our algorithm with an analytic algorithm, and demonstrate it in a hydrostatic buoyancy simulation for real-time applications, such as interactive games.

Purpose: The purpose of this study is to analyze the elderly friendliness of the serious game for dementia prevention and to seek out the influence factors for enhance the friendliness. Research design, data and methodology: It measured the elderly friendliness of the serious game for dementia prevention, run with multi-touchscreens, for 300 elderly people using the Seoul-based General Social welfare centers located at Seoul, and participants evaluated the elder-friendliness of the serious game, by responding to a questionnaire survey. In addition, it analyzed the influence relationship between the elderly friendliness (EF) and the influence factors of the serious game, by setting the factors as the game level (GL), the demand of expectations for demand (DoE) and the prevention & usefulness of cognitive decline (PUCD). Results: the findings show that most of participants positively evaluated the EF of the serious game, regardless of their socio-demographic characteristics. Moreover, it can be found that the more the 'GL DoE and PUCD', the more the 'EF'. The EF was most strongly affected by DoE, followed by PUCD, and then GL Developing and running the serious game by actively reflecting such factors may be one of ways for enhancing the participation in the serious game for dementia prevention and facilitating the sustainable use of it.

The purpose of this study is to examine the styles of street fashion in youth sub-culture which has the leading power of 1990's Korean fashion flow. This topic has been explored in documentary studies about the youth sub-culture and the background of street fashion. Then, it also continued to classify street fashion styles in order to grasp the meaning as a young fashion. The results of this study are as follows. Street fashio of Korean youth are composed of four styles. ; The first is a hip-hop style. The hip-hop of Korea is started by 'Taiji Boys' and their representative apperances are the big-baggy pants, the reversed cap, the thrown backpack. The second is a reggae style. It is formed by the singer 'Kim Gun Mo'. It features the primary color and the use of ethnic fabrics. The third is a kitch style. The kitch is definitely represented by the old, the childish and the satire appearances. It came up with the rock band 'pipiband'. The forth is a sporty style. It comes from 'basketball' and 'skateboarding' which the young people prefer. Its designs are applied from the back-number of players, the names of the teams, the stripes of active-feeling. Based on this study, I designed cloths with 3 concepts to present a new design direction of Street Fashion. Work 1, 「JOY-RIDE」 represented the freedom and the release which are shown by pop music and dance. Work 2, 「GAMMA ENERGY」 represented the dynamic energy through sports games. Work 3, 「AROUND THE CORNER」 represented the form of street including comers, walls, roads etc.

The purpose of this paper is to design a robust controller for a class of time-varying systems with bounded disturbance described by the differential equation. The robust desiging method proposed in this paper, called "incentive design method" is different from developed designing methods in the past, and has following properties. The robust control law designed by this method can guarantee a certain value of the cost functional no matter how the disturbance vary within the given bounds. Here, the certain value of the cost functional may not be a saddle-point value, but is the value selected by a system designer. Therefore, the bounded disturbance has at least no bad effect on the value of the cost functional during finite interval of time. The method is based on the theory of incentive differential games. In addition, the form of control law is constructed by the system designer ahead of time. A numerical illustrative example is given in this paper. It is shown from this derivation and this numerical example that the approach developed in this paper is effective and feasible for some practical control problem.l problem.

Developments in science and technology based on computer technology influenced military fields and created up-to-date weapons and equipment, and as a result, which is changing the war accomplishing methods of the future warfare. Due to these changes in the war accomplishing methods, the army command centers are requested to make changes in their decision-making process. In other words, they need to apply more scientific methods rather than just build a scheme by the mere analysis of commanders and the staffs as in the past. Consequently, we propose a model, Vision 21 we developed as a war game model for division-size unit analysis use, in the COA development process, which is the most important part in establishing the OPLAN for mission accomplishment. Vision 21, with a comparative analysis of the other COA built in the COA development process, can be applied to making the best COA. Model employment concept can let us choose the best COA, operating war games on condition that the COA of the opposite forces is fixed and ours sequentially opposed against, and with a comparative analysis also. Moreover, if the time available is limited, before establishing several courses, we can apply the COA to the process for making the best decision, analysing in stages or by main phases and not establishing several courses for a special purpose.

Purpose: This study was done to investigate the motivational, physical and affective benefits of exergaming in community dwelling older adult women. Methods: The research design was a nonequivalent control group pre-test and post-test design. Sixty-one older adult women over the age of 65 were recruited from 6 community senior centers to participate in the 8 week exercise intervention or control group. Six centers were divided into one of three groups: exergame, qigong exercise, or control. The exergame and the qigong exercise group received 16 sessions, scheduled twice a week, with each session lasting 50 minutes. Test measures were completed before and after the 8 week intervention period for all participants. Measures included: Grip strength, chair stand, 6 m walking, balance, geriatric depression scale, vitality and intrinsic motivation. Results: There were significant improvements in the exergame and qigong exercise group for grip strength, chair stand, 6m walking, balance, vitality and intrinsic motivation at the end the 8-week program compared with the control group. Conclusion: The exergame could be an effective alternative for older adult women to group exercise classes.
