소화시스템에 사용되는 고압의 소화가스 저장용기에는 저장용기의 파손을 막아주는 안전밸브가 있다. 이러한 안전밸브의 내부에는 원형 박판의 파열 판이 들어 있는데, 저장용기의 내압이 위험수준에 도달하면 파열 판이 파손하여 내압을 배출하는 역할을 한다. 안전밸브의 설계인자는 파열 판의 두께, 안전밸브의 유로 직경, 플라스틱 패킹 링의 내부 직경 그리고 파열 판을 고정하는 볼트 안쪽의 필렛 반경이 있다. 이중에서 파열 판의 두께는 0.2mm로 고정을 하였다. 요인배치법을 사용하여 주효과를 결정하였고 회귀방정식을 유도하였다. 이러한 회귀방정식은 추후 안전밸브의 설계에 있어서 기초 설계 자료로서 활용할 수 있도록 실험 결과와 비교하여 검증하였다. 검증실험 및 회귀방정식에 의한 결과의 오차는 약 정도인 것을 확인하였다. 그리고 반응표면법을 사용하여 기밀테스트 압력인 25MPa에서 파열할 수 있는 안전밸브의 최적 모델을 결정하였다.

본 논문에서는 고준위폐기물 처분용기를 지하 심지층에 처분하기 위하여 요구되는 구조설계 요구조건과 구조안전성 평가 기준을 도출하였다. 고준위폐기물은 높은 열과 많은 방사능을 방출하기 때문에 고준위폐기물을 넣어 보관하는 처분용기는 그 취급에 많은 주의가 요구된다. 이를 위하여 고준위폐기물 처분용기는 장기간(보통 10,000년 동안) 안전한 장소에 보관되어야 한다. 보통 이 보관 장소는 지하 500m에 위치한다. 지하 깊은 화강암에 고준위폐기물을 보관하도록 설계되는 처분용기는 내부주철삽입물과 이를 감싸고 있는 부식에 강한 와곽쉘, 위 덮개와 아래 덮개로 구성되는 구조로 되어 있으며 지하수압과 벤토나이트 버퍼의 팽윤압을 받는다. 따라서 고준위폐기물 처분용기는 심지층에 보관 시 이들 외력들을 견디도록 설계되어야 한다. 만약에 발생 가능한 모든 하중조합을 고려한 처분용기 설계가 되지 않으면 심지층에 위험한 고준위폐기물 처분 시에 처분용기에 소성변형이나 크랙 또 좌굴같은 구조적 결함이 발생할 수 있다. 따라서 심지층에 처분용기를 처분 시에 처분용기에 발생하는 구조적 문제들이 발생하지 않게 하기 위하여 여러 가지 구조해석이 수행되어야 한다. 이러한 구조해석 수행에 앞서 처분용기 설계 타당성을 평가하기 위한 기준이 필요하다. 또한 평가기준에 영향을 미치는 설계요구조건(설계변수)이 명확히 검토되어야 한다. 따라서 본 논문에서는 처분용기의 구조설계 요구조건(설계변수)과 구조 안전성 평가기준을 도출하고자 한다.

A roadmap for Electrical Safety Technology has been designed based on the study that has been contributed by the specialists, professors and researchers in electral safety field. The roadmap is divided into five major fields including, for instance, the electrical fire accidents roadmap. The other four roadmaps are for electrical shock accidents, electrical facilities accidents, electrical safety policies and electrical safety culture-education, respectively. Each roadmap has a purpose, a scope, and a technical characteristic. Following the roadmaps can result in significant reduction of electrical fire accidents, electrical shock accident victims and so forth. The result can also be utilized in guiding the planning and development of the future electrical safety technology.

In this report, we provide the focus on suggesting a method of estimating and measurement of CBM(Customer Behavior Model). Through the use of internet, a new trend of business for e-CRM on B2C Web Site known as EC has emerged. The purpose of this study is to identify the relationship between the customers of a shopping mall and CBM characteristics. It can be used to gain a better understanding of customers. From this we can determine trends, and so refine business toward customer's needs and target new products to particular customer groups. Result shows that there is a significant relationship between the customers pattern of shopping mall and CBM, CVM(Customer Visit Model).

This research analyzes clean room major fire prevention standard of clean Room(FM, IRI, and NFPA Code), the structure of Performance-Based Fire Safety Design(PBD) applied the korean fire industry situation. Performance-Based Fire Safety can operate effectively the performance of fire protection equipment & building design, so the fitness of fire safety system can be embodied by operating this. moreover, cost to be consume fire safety of real building can reduce and Performance-Based Fire Safety is considered to important technique in fire protection field. A fire in a clean room may cause a serious loss by spreading smoke particles. We will be investigated by using a computational fluid dynamics, for loss prevention by smoke spreading from one fire area to another for clean room and compared the Performance-Based Fire Safety Design with the prescriptive code design. The methodology of fire safety performance-based fire safety design and guarantee of many kinds design skill of fire system and developing design procedure will be very serious one in order to improve efficiency of domestic system. Therefore, This research will be contributing to secure safety of clean room and to set up the performance-based fire safety design in Korea by regulation for the performance-based fire safety design effectively.

In the Oriental Medicine, the physical constitution of a human being can be classified into five characteristic elements. The remedy based on the five elements constitution has revealed excellent clinical effects so far. Therefore, it may be worthwhile to conduct job design researches considering the five elements constitution for improving the efficiency and safety of job. In this study, we examine whether the theory can be applied for job design through the experiment by ‘Digital-type Speed Anticipation Reaction Tester’ or not and suggest the desirable direction of job design.

In order to protect the head, baseball helmet must to have proper strength and to absorb the kinetic energy. The purposes of this study are to validate whether the helmet have the protecting ability or not. We performed three kinds of experiment to know about the this ability. To find out the limit of displacement at 4 points(front, rear, right side, and left side), the static load by magnetic dial gauges were used, and to validate the ability of absorption, drop tests were peformed from 0.5 and 1.0 meter. Futhermore, we calculated natural frequency of the helmets by the principle of Lissajous Diagram and we performed FEM(Finite Element Method) analysis. From the results of these experiments, we found that the displacement of helmet was largest at rear point and it was smallest at left-side point(ear-covered part). The ability of absorption was better at the left-side point than the other points.

One of the objectives of any task design is to provide a safe and helpful workplace for the employees. The safety and health module may include means for confronting the design with safety and health regulations and standards as well as tools for obstacles and collisions detection (such as error models and simulators). Virtual Reality is a leading edge technology which has only very recently become available on platforms and at prices accessible to the majority of simulation engineers. The design of an automated manufacturing system is a complicated, multidisciplinary task that requires involvement of several specialists. In this paper, a design procedure that facilitates the safety and ergonomic considerations of an automated manufacturing system are described. The procedure consists of the following major steps: Data collection and analysis of the data, creation of a three-dimensional simulation model of the work environment, simulation for safety analysis and risk assessment, development of safety solutions, selection of the preferred solutions, implementation of the selected solutions, reporting, and training When improving the safety of an existing system the three-dimensional simulation model helps the designer to perceive the work from operators point of view objectively and safely without the exposure to hazards of the actual system.
