Children are out future society members but they are not well cared to be safe from various accidents. This is due to facilities were installed upon the children's for adults which can not provide safe traffic environment for children's schooling who are not fare enough experience and matured. "The Rule of declaim for school zone and it's Management"was established in the year 1995 based on the article 11 by the "Road Traffic Low". And 15,136 school zone declared by the above rule. In this study, four elementary schools located in Nowon-gu are selected and analyzed about state of elementary school, scope of school zone, installation of street furniture, and safety signs. The analysis showed that scope of school zone is currently set in 150-meter though the regulation is within 300-meter radius. Therefore, expansion of the scope is required. It is necessary to take control of vehicle during commuting times and holograms which can be noticed in school zone have to be installed as well. Through these improvements, safety zone will be offered to children effectually.

시설국화에 아메리카잎굴파리 성충 접종마리수를 달리하여 국화의 피해엽율 과 피해굴수, 피해초장율을 조사하였고 국화에 등록된 약제를 대하여 굴파리좀벌 에 안전한 약제를 선발하였다. 국화에 아메리카잎굴파리 4, 10, 20, 30마리를 접종 하였을 경우 국화에 대한 피해엽률과 피해굴수는 아메리카잎굴파리의 밀도가 높 을수록 피해수준이 높았다. 피해엽률은 12.5%, 13.7%, 21.2%, 25.4%였으며 피해 굴수는 8.8%, 12.8%, 17.4%, 19%였다. 또한 전체 초장에서 피해엽이 보이는 높이 까지의 피해초장율은 36.2%, 38.1%, 42.9%, 43.8% 였다. 아메리카잎굴파리의 접 종밀도에 따른 생육 특성은 접종밀도별로 유의한 차이는 없었다. 굴파리좀벌에 대한 저독성 약제로 살균제에서는 디비이디시유제, 크레속심메 틸액상수화제, 트리플루미졸수화제, 테트라코나졸유탁제, 비티타놀․프로피네브 수화제, 아족시스트로빈수화제, 테부코나졸수화제, 플루퀸코나졸수화제가 영향 이 없는 것으로 나타났다. 또한 살충제에서는 이미다클로프리드수화제, 아세타미 프리드액제, 티아클로프리드액상수화제, 아크리나트린수화제는 약간 영향이 있 는 것으로 나타났으며 살비제에서는 비페나제이트액상수화제, 아세퀴노실액상수 화제, 에톡사졸액상수화제는 굴파리좀벌 성충에는 영향이 없는 것으로 나타났다. 생장조정제인 에테폰액제와 전착제인 카바액제에서도 굴파리좀벌의 치사율이 낮 아서 영향이 없는 것으로 나타났다.

For the matter of elevator, one of the multi-use facilities for unspecified public, the JIS has re-established and reformed to apply to the environment in South Korea for the past 20 years. In the aspect of safety assurance, it was inevitable to suggest improved measures. The government, Ministry of Public Administration and Security has secured the safety by enhancing the safety management functions in the elevator inspection standards and expanding its safety device measures. Further, the international inspection standard has been introduced, which is about unifying inspection standard system into the international standard code. In March 14th 2012, the international standard (EN) has been amended and fully announced. Escalator and passenger conveyor among lift devices have several common danger factor that cause safety accident. First, the accident caused by decreased braking power of brake. Second, the accident caused by the rate difference between handrail and tread-board. Third, the accident caused by defects of contraflow preventing device or carelessness inspection. Fourth, the accident caused by wet tread-board or wet floor of platform which makes passenger slip and fall. As the improvements to prevent and reduce these negligent accidents, the inspection list to check and methods should be subdivided and applied for each accident likelihood cause for safety management enhancement and safety assurance of existing escalator and passenger conveyors. The escalators and passenger conveyors without safety devices in existence should be obliged to modify the part of the system or install additional safety device. With making these measures obligations, it requires to improve the system to be suitable for the international inspection standard and to have measures to prevent safety accidents. It also needs to arrange improvements for skid accident of tread-board by the external environment factors such as snow and rain.

PURPOSES: This study is to develop a road traffic sign recognition and automatic positioning for road facility management. METHODS: In this study, we installed the GPS, IMU, DMI, camera, laser sensor on the van and surveyed the car position, fore-sight image, point cloud of traffic signs. To insert automatic position of traffic sign, the automatic traffic sign recognition S/W developed and it can log the traffic sign type and approximate position, this study suggests a methodology to transform the laser point-cloud to the map coordinate system with the 3D axis rotation algorithm. RESULTS: Result show that on a clear day, traffic sign recognition ratio is 92.98%, and on cloudy day recognition ratio is 80.58%. To insert exact traffic sign position. This study examined the point difference with the road surveying results. The result RMSE is 0.227m and average is 1.51m which is the GPS positioning error. Including these error we can insert the traffic sign position within 1.51m CONCLUSIONS: As a result of this study, we can automatically survey the traffic sign type, position data of the traffic sign position error and analysis the road safety, speed limit consistency, which can be used in traffic sign DB.
