  • The purpose of this study is localization of safety relief valves fur Nuclear Service through technical development with overall design, fabrication, inspection, capacity certification test and functional qualification test of safety relief valves in accordance with KEPIC MN Code(or ASME Sec.III ). The safely relief valve is the important equipment used to protect the pressure vessel, the steam generator and the other pressure facility from overpressure by discharging the operating medium when the pressure of system is reaching the design pressure of the system. But we're depending on technology of the other country up to the present time. Because we don't have our own technologies, we have been spent the great time and money on installing and repairing safety relief valve at nuclear power plant. Therefore we have to achieve the development of safety relief valves for Nuclear Service with our own technologies.

  • Seismic isolation has developed to the point where it may be considered as a viable design alternate for a wide range of building structures. However, it needs to consider various aspects to adopt a suitable isolation system for buildings practically. This report presents the basis for the preliminary design procedure which has been developed for the seismic isolation system using the lead rubber bearings. The design procedures have been developed to ensure that the bearings will safely support the maximum gravity load throughout the life of the structure while they provide a period shift and hysteretic damping during the design earthquake.

  • The severe acute respiratory syndrome -SARS virus spreaded rapidly in Asia in 2003 caused a lethal and serious epidemic. Establishing special isolation wards of high-level epidemic prevention has becomes one of the most important tasks of epidemic prevention. Taking the biosafety level of US CDC biology laboratory as an example, the laboratory of the highest level, BL4 and that of the second high level, BL3 are only allowed to handle and research this kind of highly dangerous viruses safely, to ensure the safety of researchers and the surrounding environment.This research aims to study the functions and the design requirements of "special isolation wards", which is equivalent to the high-level biotechnology laboratory, and have an integrated discussion about the design and construction techniques of this kind of wards, expecting to provide a reference for constructing special isolation wards and maintaining operation safely in Taiwan.

  • Nowadays the numbers of the aging population are rapidly increasing in Korea, which became the 'aged country' from the year 2000. These aged people are getting more important consumer group and the products and services related to the silver industry are getting bigger. Universal fashion design is based on the concept of universal design that pursues the 'design for all'. This study aims to understand the physical, physiological, and psychological characteristics of the elderly women and apply the principles of universal design to universal fashion design for the elderly. Korean traditional vest, 'Baeja' was used as the design inference for the target of age 55 and older. This group is also called as 2Y2R(too young to retire), Tonk(too only no kids), Y-O(young-old) generation, or OPAL(old people with active life). Principles of universal design such as accessibility, flexibility in use, fair in use, aesthetics, safely-oriented were applied in developing the vest. This universal fashion products enable the elderly to have physical independence and make them have the self respect and better life.

  • Offshore Bridge Crane and Hoist which are used FPSO Ships that can move through self - power and have oil production, store and loading and unloading facilities are increasing demand. These equipments must use Crane safely by pitch and rolling of the high wave. For this, they have to be equipped with high durability and safety. So the advanced shipbuilding industries use a private design system which can be prompt in design and analyze in the first stage. For this study, It was developed a basic design system for "Bridge Crane and Hoist" used on FPSO ships. By developing this automated system for "Bridge Crane and Hoist" design, we will be able to make the design data easy to understand. This basic design system will help reduce the amount of working time it takes to design new systems, construct design databases and get approval for the finished design.

  • The objectives of railway construction and operation are transportation of passenger and freight safely and punctually. However, environmental effects such as noise, vibration, air pollution, underground water pollution and change of biosphere are emerged caused by train pass-bys. To avoid these adverse effects, new railway system has been developed around the world. This paper introduces LRT system and its environmental advantages. An environmental consideration for LRT design and adoptability for Korean situation are studied for the more.

  • The objective of this paper is to develop an expert system for nuclear piping integrity. This paper describes the selection methodology of integrity evalution method and the inference of material properties. To select the integrity evaluation method, the weight factor for respective material properties was obtained by the sensitivity analysis of the effect of material properties on integrity evaluation method. Subsequently the possession ratio for respective integrity evaluation method was computed, and the most appropriate integrity evaluation method for given input information is selected. In the material properties inference, stress-strain curves and J-R curves were predicted from tensile properties such as yield strength and tensile strength.

  • The brake system is important to stop train safely. The train is sloped by regenerative brake and pneumatic brake which are continuously blended at service brake. When service is applied to train, it is controlled by train weight and brake command. The jerk limitation function is applied for impulseless smoothing braking. All brake applications in service condition have a function of the variable load control to keep the braking effort in proportion to each car load. All of control function are performed by brake controller. Therefore, we will propose the design of brake control system in order to control efficiently
