In this study, with the objects of 173 institutions of university and research institutions, investigation was carried out through visit investigation ar d questionnaire investigation. Frequency and severity of occurrences was acquired mainly through universities and research institutions which have reported occurrences of accidents to the Ministry of Education, Science, and Technology. Quantitative danger evaluation was conducted through frequency and strength of occurrences. Case study was carried out by selecting bio science laboratory of university and as the result of this study, degree of danger among the inspection objects of bio science laboratories, laboratory work place was evaluated as the most dangerous with the scores of 155.00 and as the result of average danger level, compression gas cylinder was evaluated as the most dangerous with the scores of 6.4000.

산림 인접 시설은 산불의 발화원이자 주요 보호대상으로써, 이에 대한 관리를 위해 위험 정도를 판정하는 것은 진화 우선 순위의 결정과 인명과 재산의 보호를 위해 매우 중요하다고 할 수 있다. 본 연구에서는 산림 인접지 내 시설물의 인공적 요인에 의한 산불 위험성을 평가하기 위해, 접근경로 특성, 진화용수의 접근성, 진화기관으로 부터의 거리를 이용하여 산불 위험성을 평가하였으며, 또한 이를 이용하여 지도화 작업을 수행하였다. 분석 결과, 산불 발생 시 진화 차량의 접근에 어려움을 겪을 것으로 예상되는 지역의 면적 비율 분포는 봉화군(26.3%)> 울진군(24.6%)> 경주시(21.9%) 순으로 조사 되었으며, 진화용수와 관련된 위험성을 보이는 지역의 분포는 울진군(9.8%)>경주시(7.2%)>봉화군(6.2%) 순서로 조사되었다. 또한, 진화기관과의 이격거리로 인해 위험한 지역의 분포는 울진군(11.0%)> 봉화군(6.3%)> 경주시(1.5%) 순으로 조사되었다. 이를 이용하여 지도를 제작하였으며, 보다 향후 추가적인 연구와 타 지역에의 적용을 통해 지속적인 보강이 필요할 것으로 사료된다.

This paper proposes a method of avoiding obstacles and tracking a moving object continuously and simultaneously by using new concepts of virtual tow point and fuzzy danger factor for differential wheeled mobile robots. Since differential wheeled mobile robot has smaller degree of freedom to control and are non-holonomic systems, there exist multiple solutions (trajectories) to control and reach a target position. The paper proposes 'fuzzy danger factor' for obstacles avoidance, 'virtual tow point' to solve non-holonomic object tracking control problem for unique solution and three kinds of fuzzy logic controller. The fuzzy logic controller is policy decision controller with fuzzy danger factor to decide which controller's result is more valuable when the mobile robot is tracking a moving object with obstacles to be avoided.
