국내 철도분야 SOC 투입은 거점도 시간 이동을 위해 집중되어 왔으며, 상대적으로 중·소도시 및 수도권 인근 도시간 이동을 위한 교통인프라 투자가 상대적으로 이루어지지 않고 있어 도시간 이동을 위한 시간적, 비용적 문제가 대두되었다. 중·소도시간 이동수단이 열악함에 따라 경제, 문화 생활공간이 단절되어 있어 도시발전에 장애가 되고 있으므로, 원활한 교통수단을 제공함으로써 지역경제를 활성화할 필요가 있다. 따라서 도시와 도시를 연결하고 번거롭게 갈아타는 불편함을 없애고 도심 내에서 타 도심 내로 바로 접근이 가능한 대중교통 시스템의 개발을 통해 이역간 이동을 쉽게 할 필요가 있다. 또한 일반 철도와 기존 차량의 시스템과의 간섭을 없애기 위해서는 국외 시스템의 기술적 한계(100km/h)를 뛰어 넘는 한국형 Train-tram기술(200km/h급이상) 개발을 위한 시스템 설계 및 이를 달성하기 위한 핵심기술의 개발이 필요하다. 따라서 본 논문에서는 200km/h급 Train-tram 시스템의 성공적인 국내적용을 위해 해외 사례 및 앞으로 연구동향에 대해 조사·분석하였다. SOC Insertion of domestic railway field has been concentrated for time shift between urban cities, and since the transportation infra investment for small, middle cities and adjacent capital area movement is not relatively consisted, temporal and spatial problems of migration between cities has arisen. Since means of transportation among middle and small towns are poor, economy, culture and living spaces are separated, which causes obstacles of city development. Therefore, we need to facilitate local economy by offering proper and means of transportation. Thus, it is needed that eliminating the inconvenience of transferring stations by connecting cities and developing a possible and adjacent public transportation system for providing easy access from inner cities to outer cities to the public. In addition, in order to remove the interference of system between general railways and pre-existing car, system plan to develop Korean Traintram technology (more than 200km/h class), which exceeds the technology limit(100km/h) of foreign system and development of core-technology to achieve above are needed. Therefore, this thesis researched and analyzed the examples of foreign countries and future trend of study for applying 200km/h class traintram system successfully into Korea system.

This study is a basic research study for systematic and integrated operation of school safety checklist and inspection table conducted in schools for building safe environment in domestic elementary, middle, and high schools. To do this, it collected safety inspection checklist data conducted in 17 metropolitan and provincial education offices, classified inspection periods of checklists according to periods, and analyzed a single checklist by selecting one among other mandatory checklists adopted in schools. In this way, it was classified into a standard of “Domestic Seven Safety Standard for School Safety Education.”

The purpose of this study was to investigate the influence of balancing interference on the activity of masticatory muscles and condylar path. Eight dental students of Won Kwang University without any symptoms of temporomandibular disorder and occlusal interferences, were selected for this study, The balancing interference was provided by construction and cementation of cast metal crowns on the upper and lower first molars. For the measurement of muscle activity, bioelectric processor (EM2, Myotronic Res., Inc., U.S.A.) was used and for the condular path, computerized electronic pantograph (Pantronics, Denar Corp., U.S.A.) was used and the myographic recordings were taken bilaterally from the anterior temporal, masseter and digastric muscles on rest position and on functions. These experimental procedures were done before cementation of experimental crown, three days after cementation of experimental crown, one week after, two weeks after and then one week after removal of experimental crown. The results are as follows: 1. The PRI score was increased at three days after application of balancing interference, and decreased at two weeks after. 2. Three subjects showed mild symptom of temporomandibular disorder at three or four days after application of interference, but the symptom was subsided in one or two weeks after application of interference. 3. One week after application of balancing interference, the activity of ipsilateral anterior temporal muscle in four subjects was decreased on gum chewing at experimental site. 4. Three days after application of balancing interference, the activity of ipsilateral anterior temporal muscle in three subjects was increased on gum chewing at non-experimental site. 5. The influence of balancing interference on the activity of anterior temporal, masseter and gigastric muscle was not prominent.
