  • This study is concerned with the loss rate calculation for evaluating the safety of aircraft series. The objective of this study is to provide the estimation method of safety for the determination of aircraft series, when the aircraft is directly purchased off-the-shelf or co-produced. Especially, in case the initial operation capabilities of alternative aircrafts are substantially different, this research proposes the modified cumulative average method which can effectively estimate the safety of aircraft.

  • Currently, Safety accidents have been raised & more concerned despite that Government has emphasized on preventing accidents in construction area of Korea. An accident is due to several causes of it, thus this the study, as the above, will specify the methodology to establish more effective safety prevention plan, itself, compared to most studies being based on a case, specially for the projects under Far-East District, Corps of Engineers, USA. Additionally, this study will be limitted for performance method and the projects will not be classified with the same sorts as domestic ones are.

  • Automobiles have become part of our lives in modern society. But since they can be detrimental once problems occur on the road safety requirements are stringent. In this paper DFSS procedure is applied to the establishment of headliner safety. Specifically, IDDOV is employed where problems are identified, areas for development clarified, optimization realized, and finally optimal conditions verified at the final stage.

  • 본 연구는 선행 연구로 진행되었던 수직상승형 고소작업차의 개발을 위한 구조해석 및 원격 제어를 포함한 중앙집중식 컨트롤러 및 유압식 상승리프트 개발에 관한 사후 연구로 진행되었다. 기존에 연구를 진행하면서 개발하였던 고소리프트의 구조 변경을 통하여 안전성 검토를 실시하였다. Solidworks로 3D 모델링을 진행하였으며, Hypermesh S/W를 통하여 유한요소의 모델을 생성하였다. 또한, 평가를 위한 작업차의 적재 환경은 작업 테이블에 위치별(전체, 상좌, 상우, 하좌, 하우)로 적재량이 250 kg인 조건, 작업 테이블에 위치별(전체, 상좌, 상우, 하좌, 하우)로 적재량이 600kg인 조건으로 하여 구조해석을 진행하여 다방면으로 안전성을 검토하였다. 그 결과 허용 적재량 250 kg과 초과 적재량 600 kg에 대해서 최대응력이 발생하는 부품을 제외한 결과를 살펴보면(Case-11 제외), 응력 수준은 항복강도 이하임을 알 수 있다. Case-11의 경우에는 최대응력이 발생하는 부품을 제외한 후에도 상단의 안전바 중앙 지지부에서 항복강도를 초과하는 영역이 존재하지만, 최대응력이 발생하는 부품과 같이 전체 구조물의 안전성 측면에는 영향을 미치지 않을 것으로 사료된다. 변위(처짐) 결과를 살펴보게 되면, 모든 경우에 있어서 동일하게 테이블에서 최대 처짐이 발생하는 것을 알 수 있으며, 250 kg과 600 kg 모두 처짐이 발생하는 경향은 동일한 것으로 나타났다.

  • If industrial disasters happen at workplace, work's desires of workers and business activities may be dispirited. Especially, industrial disasters frequently happen in the field of heavy and chemical industry companies. According to report of the korea occupational safety and health agency(KOSHA), damage due to industrial disasters is more 5 times than losses due to industrial strifes. Thus, in these manufacturing companies, a safety management field for preventing industrial disasters is emerging as an important factor of business activities. This paper proposes an industrial disaster prediction model for safety management and also implements industrial safety management system(after this, is called as u-Safety system) based on the proposed model using ubiquitous computing technologies like USN(ubiquitous sensor networks) which are given much attention among recent information technologies. The implemented system is successfully operating in the shipbuilding division of 'H' companies.

  • Safety accident rate of small-medium construction site is high. because of lack of safety management system, lack of safety management capacity, lack of investment for safety, Owner's insufficient awareness about safety. In order to improve this, Currently in Occupational Safety and Health Act, Construction site of amounts more than 300 million won less than 120 billion (architectural),150 billion won(civil) mandatory subject to the technical guidance on construction accident prevention. Context of construction accident causes with construction accident rate relationship analysis and case analysis of technical guidance, through a survey of stakeholders in the technical guidance drawn the problems of the construction accident prevention technical guidance system and ways to improve on this.

  • It is difficult to put it into practice in that it requires bearing too much burden to draw out the planning itself in a case of large construction work. Consequently in this paper we select evaluation criteria by construction progress, classify into several categories, and regard potential danger which often occurs, as a evaluation criterion. Further step is to allow workers or collaborated companies to express their expert opinions or experiences and to encourage quality and process control and autonomous safety control by applying PSM(Process Safety Management) method using AHP(Analytic Hierarchy Process) and to development of PSIM(Process Safety Information Management) evaluation method in the construction. The reason why PSIM method should be quantitative and substantial progress is because it contributes Korean constructing companies to enhancing their safety control ability and to taking an equal stance just like developed countries, thereby strengthening their competitive edges.

  • The purpose of the research is to discuss the product safety procedures for the food industry The producer and supplier of the products should satisfy the increasing consumer safety needs. To develop and produce safe products, the food industry must rigorously perform potential hazard findings and very thorough risk analysis to detect even the very minute potential danger. The ultimate product liability rests with the consumer safety and the manufacturer's capability which competes in the market places. This is especially important in the food industry. However, small to medium sized food producing companies are facing challenges in this area due to their overall capabilities. Therefore this research presents safety procedures which are relatively simple to implement.
