The necessity of universal design for forestry is increasing. Although several studies applied universal design in forest site, they had been only concentrated on the barrier-free design for the limited activities rather than overall utilization for considering all visitors from the disabled, the elderly and the infirm to the baby and child. The purpose of this study is to find out the principle of the universal design within forest welfare service facilities by analysing how socially disadvantaged people perceive overall usage of natural recreation forest area. This study figures out the main principles of universal design in forest welfare through analyzing usage of children and disabilities in Yumyeongsan natural recreation forest where is one of the popular type of forest welfare area. By doing focus interviews targeted on children and disabilities, the results are analyzed through semantic network analysis, objectively. The result proves that universal design in forest welfare area contains four principles; convenience, safety, diversity and amenity. Also it confirmed that disabilities need better internal space facilities and priority care. Through those characters of universal design, forest area will be able to cover more various type of users as forest welfare area.

The purpose of this study was to scrutinize the current tendency of Universal Design. The analysis unit was presentation in the proceeding of "The first International Universal Design Conference" which was held at New York in June, 1998. Sixty the presentations in the conference were analyzed using Content Analysis technique. The analysis criteria were academic vs. practical, themes, subjects, levels of UD concepts, design principles applied, and type of disability. The results were as follows. Compared with its early characteristics such as practical approach, architectural living environment, barrier free for the disabled, especially for person with mobile disability using wheelchair, and the emphasis of accessibility, UD characteristics shown in the conference evidenced a dramatic shift from them toward the new century : Its subjects became a wide range of people including the disabled departing from 'the disabled' only; The range of disability was expanded to include visual and audial disability departing from mobility only; Themes appeared very diverse such as both small and large scale environments, products, dissemination, and theory from the 'architectural environment'; Various design principles were added to early accessibility ; Commercialism was added to early Welfarism. Therefore, this conference provided empirical evidence that UD changed considerably from its early development in many aspects. It indicated the potential of UD as a big wave in the 21st century design.

The development of Korean textile industry has continued for the early industrialization. But a change in situation of circumstances, textile industry undergoes hard times. To overcome the barrier, therefore, technical development and design innovation are needed to make high value added product. This paper try to put to practical use of the silk weighting process technique(WPT). First, we investigate the technical trend of WPT to summarize the theory, and examine the feasibility of technical development. Second, the application of Graft process to silk textile is examined to know whether it is possible as an practical use. Next, we present the practical way of WPT using MAA monomer through experiment. The results are as follow. 1) Considering the lack of silk yarn. Graft process is appropriate new technique to make the value added product, and fine quality. 2) Studing textile goods, it need inter-displlinary co-work not only fiber engineering scope because textile goods is closely related with fashion industry. 3) MAA monomer used in this paper is more excellent then other monomer because it has good weighting effect and does not harm to the nature of textile. 4) MAA WPT is good for silk textiles of ladies jacket and neck-tie.

Recently vehicle development trend puts emphasis on cost reduction and performance improvement through weight reduction, and safety security to protect passenger and chassis against external impact. Primary factors effected on vehicle safety are chassis structure, chassis system, and safety equipment like bumper. Research in part of weight reduction is proceeding actively about prohibition of over-design and material through optimal design method. Bumper in these factors is demanded two of all factors, safety security and weight reduction. It is the part that prohibits or reduces a physical impact in low speed crash. Bumper is composed of a few parts but this study exhibits the shape of bumper rail has a role on energy absorption of safety security and weight reduction from structure analysis of bumper rail's variable shape surface.

Reliable prediction of nuclear fuel rod behavior of nuclear power reactors constitutes a basic demand for steady-state calculations, design purposes, and fuel performance assessment. Perfect design of fuel rods as the first barrier against fission product release is very important. Simulation of fuel rod performance with a code or software is one of the fuel rod design steps. In this study, a software program called MARCODE is developed in MATLAB environment that can analyze the temperature distribution, gap conductance value, and fuel and clad displacement in both solid and annular fuel rods. With a comparison of the maximum fuel temperature, fuel average temperature, fuel surface temperature, and gap conductance in solid and annular fuel, the effects of a central hole on the fuel temperature distribution are investigated.

This paper aims at suggesting design guidelines for a perimeter-less HVAC system that contributes energy savings. Perimeter-less HVAC system is one that relieves difficulties fuck as handling mixing loss, uneven radiative environment, and maintenance and repair. It prevents heat load gained through window and outdoor wall without modifying a previously equipped building skin system. In this paper, we performed several kinds of CFD (computational fluid dynamics) cases through numerical simulation to obtain an optimized perimeter-less design, and then we conducted a large-scale model experiment to see how the push-pull air flow would handle indoor heat to obtain an optimized perimeter-less design.

This paper presents a study on the design parameters that consider the magnetic saturation effect in a rotor core of a synchronous reluctance motor. Two important design parameters in a rotor are selected to analyze the saturation effect of a synchronous reluctance motor, particularly in a rotor core. The thickness of the main segment, which is the main path of the d-axis flux, and the end rip, which affects the q-axis flux, are analyzed using the d-axis and q-axis inductances. Moreover, the characteristics of torque and torque ripple when magnetic saturation takes place are analyzed. The saturation effect is verified by comparing the reluctance torque between the experiment and FEM simulation.
