The analysis of the visual impairment and refractive errors among 4,004 school children in Seoul in 1986 with ancilliary questionnaire on various socio-environmental and visual factors was conducted. The number of the student with subnormal vision (0.7 or less) was 1,552 (38,8 %), and the rate of subnormal vision was increased with the higher grading of the school classes. Rate of myopes among the 1,552 students vision 0.7 or less consists of 52 % in primary school, 83.5 % in middle school, and 94 % in high school, and they were increased with the higher grading of the school class. The acutest increase of rates were observed at the stages of 2nd year class of male, and 1st year class of female at the middle school. Among the glasses-wearer of myopic students of vision 0.5 or less, the rate of adequately corrected cases was 42.5 %, whereas the overcorrected in 6.8 %, and undercorrected in 49.3 %. The main reasons of glasses negligence among the non-possessor of glasses with the vision of 0.5 or less were indicated in prominence of numbers of' "no complaints without glasses" (42 %). "unawareness of visual disturbance" (20%), "annoyance with wearing glasses" (13.4%), and "no permission from parents" (11.5 %) rather than the "economical reasons". The amblyopic components were estimated 126 cases (3.2%) in combination of refractive errors. According to the analysis of ancilliary questionnaire, the-conclusion with the statistical significance was that the myopization of the children's eyes appeared susceptible with a number of socio-environmental factors including the eating habits, length of T.V. watching period and distance, reading distance and type of illumination during near work, and school achievement. The possibility of prevention in some extents of progress of the myopia following the improvement of the relevant environmental factors in younger stage of children would be considered as deducible one.

Social problems are coming to light due to the dysfunction which is caused by the improvement of ICT and the increasing information with computers and one of these problems is teenagers' computer toxicosis. In order to measure such an toxicosis, test paper that is developed by Kimberly S. Young is typically used. In this study, along with the test paper, localized Korean Internet addiction test (K-index) was used and the study was also made on the basis of such result. With results of sorting the data on the basis of K-index diagnosis criteria, it showed general users were 534 (64.8%), with potential risk users were 229 (27.8%) and high risk users were 61 (7.4%). This study was for the purpose of finding out sufficient and essential conditions ( outer behaviors ) of computer toxicosis for high risk users and searching for preventive measures for them.

Materials and Methods: We analyzed 162 match injuries of middle and high school athletes, who were surveyed in 2005 and 2006 national tournament. Results: Among 162 match injuries, injuries in foot and hand were the most common and there were 35 cases in serious injuries such as fracture, open dislocation, open fracture of epiphyseal plate and so on. The very fast speed and destructive power of Takwondo athlete can cause open dislocation of great toe and can cause fracture of foot and upper extremity when kicking. Conclusion: We consider that injured athletes need proper treatments and sufficient rest not to accumulate training injuries and match injuries and need to improve mats of stadium, braces for feet and hands and put on braces for elbows to prevent match injuries.

Male is about two times higher than female by 66.6% in the injury incidence. In terms of the injury mechanism, the injury(22.2%) by hit is the first, the traffic accident(21.5%) is the second, the slippery(16.8%) is followed. The injuries were occurred most largely at 16:00-20:00(33.4%), and the 33.6% of injury by daily leisure activity occurs at 16:00-20:00 chiefly. Conclusion : Analysis using the data of the injury surveillance system has some advantages compared to the previous research such as reliability and specification. To prevent the students injuries, not the individual problem but the social dimension should be acknowledged so that we can secure and promote the safety from the risk.

The definition of the national security is that the lives of its people and the property of the country must be kept from the enemies. The people in the country must have the awareness of national security in their mind, and the fate of the country relies on the security awareness of the people. Most of college students are to have their own goals trying to fulfil in their life. If the national security is not guaranteed, it will not be possible to achieve their dreams and goals. Currently, most of college students have been trained only for passing college entrance exams in their growth processes, and some of them are confused with political, social, and cultural identity. College students are spending most of time on the preparation for getting employment, so they are indifferent to the national security of their country. After the seminar for college student's unification and security, we will survey how much they could be changed and propose the guidelines for college student's security awareness.
