Recently, retrieval of various video data has become an important issue as more and more multimedia content services are being provided. To effectively deal with video data, a semantic-based retrieval scheme that allows for processing diverse user queries and saving them on the database is required. In this regard, this paper proposes a semantic-based video retrieval system that allows the user to search diverse meanings of video data for electrical safetyrelated educational purposes by means of automatic annotation processing. If the user inputs a keyword to search video data for electrical safety-related educational purposes, the mobile agent of the proposed system extracts the features of the video data that are afterwards learned in a continuous manner, and detailed information on electrical safety education is saved on the database. The proposed system is designed to enhance video data retrieval efficiency for electrical safety-related educational purposes.

국민안전처는 2016년 국민의 생활안전 기반 강화를 위한 정책으로 맞춤형 소방안전교육과 소방안전문화 확산을 위한 정책을 추진하고 맞춤형 소방안전 교육체제 마련을 위해 소방안전교육 인프라 확충을 위한 방안을 계획 중이다. 이는 그간 우리사회의 안전에 대한 문제점을 개선하기 위한 방안으로 본 연구가 선행되어진 이유이기도 하다. 현재 안전교육이 시행되고 있으나 실제현장과 같은 상황을 체험할 수 없고 교육에 대한 만족도도 기초적인 수준에 불과하다. 이에 이러한 문제를 해결하기 위한 효과적인 대안으로 VR 소방체험교육콘텐츠를 제안한다. 이는 가상공간에서 화재진압과 대피훈련에 대한 체험교육을 목적으로 1)소방체험교육현장에서 안전하게 활용 2)흥미유발을 위한 인터랙션 UI 제공 3)동작인식기술과 조작 컨트롤러를 개발 사실감 증대 4)예산절감의 경제적 효과를 기대할 수 있다. 이에 VR 디자인 환경요소와 VR 교육콘텐츠 개발사례를 통해 체험교육의 학습적 효과를 알아보고 UX 디자인방법론(Persona, Task Scenario)을 적용하여 VR 소방체험 시스템 구조와 하드웨어를 구성한다. 또한 HMD 환경에서 조작과 몰입 감을 유도할 수 있는 VR 전용 동작인식과 컨트롤러의 통합 플러그인도 개발한다.

This study deals with characteristics and risk of a PM based on user survey result, road driving test and data analysis of PM accident. Text mining method is applied to extract PM accident data from Big Data, which are claim data of private insurance company. Road driving test and survey on safety, convenience, noise, overtake ability, steering ability, and climbing ability of PM are performed to evaluate user's safety and convenience considering domestic road condition. As the result of claim data analysis, annual average increase rate of PM accident is 47.4% and average compensation of personal mobility is higher than that of bicycle by maximum 1.5 times. 79.8% of PM accident is self-caused accident due to unskilled driving and age-specific diagnosis rate of driver over 60 is higher than that of under 60. Diagnosis rate of over 60 at lower limb, foot, rib and spine is especially higher than that of under 60. As the result of road driving test and user survey, satisfaction level on safety and convenience of PM is evaluated as close to that of bicycle and satisfaction level of PM is increased after boarding. Overtake ability, steering ability, and climbing ability of PM are evaluated as same or better than that of bicycle but warning equipment to pedestrian or bike such as horn is required because noise level of PM during driving is too low. Finally, user survey result shows that bicycle road is suitable for PM and safety standard, advance-education and insurance are required for PM. It is suggested that drivers' license for PM can be replaced by advance-education. Results of this study can be used to prepare safety measures and legal basis for PM operation.

This study presented the development of a user centered school facility fire safety evaluation model that would support fire safety evaluation, which is globally recognized as being important in terms of school safety, to be more efficiently implemented in the school field mainly by students. The study consisted of five steps. First, actual condition survey tools were developed based on the major fire safety evaluation items derived through literature review. Second, the characteristics of domestic school facilities in terms of fire safety were developed using the survey tools. Third, an evaluation model at a level utilizable by students was developed based on the foregoing characteristics. Fourth, the applicability of the model was verified through a trial application of the model to elementary school students. Finally, legal and institutional improvement plans and fire safety education materials were presented through a policy proposal.

Safety certification and inspection of dangerous machines and equipments used in industries are to save lives of workers and properties involved. Cause analysis of industrial accidents is essential to prove the effectiveness of such certification and inspection. This study focuses on suggesting systematic method for cause analysis of industrial accidents associated with dangerous machines and devices. Incorporating transition from the current user-oriented indirect regulations to more manufacturer and user balanced direct regulations, suggested method coupled with safety certification, safety inspection, safety management and safety education will guarantee more effective prevention of industrial accidents.

본 연구는 특정 사용자들이 효과적으로 사용할 수 있는 VR 안전교육콘텐츠를 개발하기 위해 사용자 참여 디자인 방법론(UCD)을 적용하였다. 이에 따라 UCD 기반의 설계를 통해 얻은 인사이트를 VR 매체에 특화시키고, 효율적인 설계 활동이 가능하도록 방법론을 개발하였다. 개발된 UCD는 다음과 같은 주요 활동으로 구성된다: 첫째, 사용자 니즈와 관련된 다양한 자료를 활용하여 설계 방향을 수립하는 '컨셉 도출'; 둘째, VR 특성을 내용과 구현적 측면으로 나누어 설계하는 '디자인 설계'; 셋째, 프로토타입을 구현하는 '개발'; 넷째, 사용자 집단을 포함한 전문가와 일반인 집단으로 종합적인 검토를 진행하는 '평가'; 마지막으로 최종 콘텐츠를 완성하는 '완료'이다. 본 연구에서 제안하는 프로세스는 기존 UCD와 달리 콘텐츠 개발 과정이 설계 내용 개선에 집중될 수 있도록 다음과 같이 탄력적으로 운영할 수 있다. '① 디자인 설계 → 개발 → 평가 → 완료', '② 디자인 설계 → 개발 → 완료', '③ 디자인 설계 → 개발 → 평가 → 보완 → 디자인 설계 → 개발 → 평가 → 완료' 등으로, 이를 통해, VR 안전교육콘텐츠의 품질과 사용자의 만족도를 높일 수 있다.
