게임산업은 21세기 정보화 사회의 문화 컨텐츠 산업의 한 분야이다. 멀티미디어, 3차원 그래픽, 3차원 음향, 가상현실 분야, 캐릭터 산업 등과 맥락을 같이 하는 핵심 기술 집약 산업이며, 문화적 파급효과와 규모가 점점 커지고 있는 산업이다. 그러나 국내의 게임 개발 능력은 선진 미국이나 일본에 비하여 낙후되어 있다. 정책적으로 게임 개발 지원 사업이 행하여지고 있으나 게임 컨텐츠 영역보다는 인터넷 게임 혹은 3차원 그래픽 엔진 개발 등 게임 소프트웨어 엔진 개발에 치중되어 있는 것이 현실이다. 한편 미국 PC게임 시장에서 만 8세 이하의 아동용 게임 시장은 전체 게임 시장의 삼분의 일을 차지하는 거대 시장이다. 재미요소와 교육요소가 접목된 아동용 게임은 컨텐츠 위주의 산업으로 짧은 개발 기간에 고부가가치를 창출 할 수 있는 산업이기 때문이다. 본 연구는 기존의 컴퓨터 게임에 관해 고찰하고, 아동의 연령별 특징에 적합한 게임요소의 추출과 새로운 게임 컨텐츠를 제안한다는 것을 목적으로 한다. 앙케이트 조사와 프로토콜 분석 및 연령별 성장기 특징의 문헌조사를 통해 기존의 게임장르에 추가하여 'Asports', 'Asim' 'U.J RPG', 'S＋RPG'가 성장기별 아동 발달에 유익하다는 결론을 도출 할 수 있었다.

Purpose: As the influence of mass media increases, the general standard of attractiveness or beauty of a face also changes. The primary purpose of the study is to find out the factors of the attractive and beautiful face recognized by public. Methods: We picked out standard model photography and operated with Adobe$^{(R)}$ Photoshop$^{(R)}$ and Monariza$^{(R)}$ virtual plastic surgery program. The contour of face, eye, nose, forehead, zygoma, chin and proportion of upper, middle, lower face were changed. The interview survey was conducted through structured standard photo for 310 respondents. That was utilized in the final analysis. Multiple regression analysis was executed by SPSS 12.0. It was used to deal with statistical data and all the other necessary analysis. Results: According to general characteristics of the respondents, many differences were found in preferred face and facial aesthetic subunits. The younger generation preferred the lozenge and inverted triangle shape contour. The respondents over 40 of age preferred the egg shape contour. In chin and zygoma contour, the respondents at the age of 20 preferred distinctly small chin and relatively small lower face. On the other hand, the respondents over 40 of age preferred the wide zygoma relatively. In the proportion of upper, middle, lower face, 51.0% of respondents answered 1 : 1 : 1. If they want to have an aesthetic operation, they preferred protruding forehead. Also they preferred the small chin and V-shaped chin in frontal view. Conclusion: Many respondents preferred to have a plastic surgery for the better facial subunit. The statistical evidence from this study suggests that the harmony and balance of facial aesthetic subunits make attractive and beautiful face.

In this thesis, based on Genetic Algorithm, a new route search algorithm is presented to search an optimal route between the origin and the destination in intelligent route guidance systems in order to minimize the route traveling time. The proposed algorithm is effectively employed to complex road networks which have diverse turn constrains, time-delay constraints due to cross signals, and stochastic traffic volume. The algorithm is also shown to significantly promote search efficiency by changing the population size of path individuals that exist in each generation through the concept of age and lifetime to each path individual. A virtual road-traffic network with various turn constraints and traffic volume is simulated, where the suggested algorithm promptly produces not only an optimal route to minimize the route cost but also the estimated travel time for any pair of the origin and the destination, while effectively avoiding turn constraints and traffic jam.

Deliberate self-harm (DSH) is the act of deliberately harming your own body, such as cutting or burning yourself, without suicidal intent. It has especially become a problem among adolescents and college-age students in institutional settings such as boarding schools, Greek houses, detention centers and hospitals. We focus on contagion of DSH among adolescents and young adults by creating a deterministic epidemiological model. We study the impact of actual peer pressure, virtual peer pressure (the Internet) and treatment analytically in terms of a basic reproduction number through stability analysis of a system of ordinary differential equations. All parameters are approximated and results are also explored by simulations. The model shows that DSH is present in an endemic state in the population considered, and the control strategies are discussed.

This study reviews several innovative electronic reference services that will be transformed in the age of the virtual library. This study focused on reference service via E-mail and electronic bulletin board which is regarded as the most important service in a variety of electronic reference services. Through E-mail and the electronic bulletin board, the user submits questions and the librarian responds with the answer. Though interest in using E-mail and electronic bulletin board as a basis for reference service has grown considerably in recent years, it is still in its infancy in Korea. Thus the purpose of this study is to propose a model electronic reference service system using E-mail and the electronic bulletin board for university libraries in Korea. This system consists of the following modules: electronic reference services policy, open reference service via electronic bulletin board, closed reference service via E-mail, and FAQ. This system is meant to be a guide for those considering implementing such a service.

Objective: The purpose of this study was to investigate the effects of three visual conditions (eyes opened, eyes closed, and wearing of a head mounted display [HMD]) on single-leg standing through kinematics and kinetic analysis. Method: Twelve college students (age: $24.5{\pm}2.6years$, height: $175.0{\pm}6.4cm$, weight: $69.2{\pm}5.1kg$) participated in this study. The study method adopted three-dimensional analysis with six cameras and ground reaction force measurement with one force plate. The analysis variables were coefficient of variation (CV) of the center of body mass, head movement, ground reaction force, and center of pressure, which were analyzed using one-way analysis of variance with repeated measures according to visual conditions. Results: In most cases, the results of this study showed that the CV was significantly higher in the order of HMD wearing, eyes closed, and eyes opened conditions. Conclusion: Our results indicated that body sway was the largest in the HMD wearing condition, and the risk of falling was high owing to the low stability.

For the purpose of decreasing economic loss from the traffic jam, a car route guidance system efficiently utilizing the existing roads has attracted a great deal of attention. In this paper, the search algorithm for optimal path and alternative paths, which is the main function of a car route guidance system, was presented using evolution program. Search efficiency was promoted by changing the population size of path individuals in each generation, applying the concept of age and lifetime to path individuals. Through simulation on the virtual road-traffic network consisting of 100 nodes with various turn constraints and traffic volumes, not only the optimal path with the minimal cost was obtained, avoiding turn constraints and traffic congestion, but also alternative paths with similar costs and acceptable difference was acquired, compared with optimal path.
