In an information-oriented and internationalized society of the future, the quality and the price of goods made by each country will be equalized. That eliminates competition. But the design and appearance of products is an important factor in international competition. Indeed, design symbolizes a country's culture visually, and it can show the cultural identity and originality of a nation in international society. And that will play an important part that can contribute to creating added value. It is necessary to revive our people's old lyrical stories which are far away from our memory, and we badly need design development to revive traditional cultural merchandise through visual modernization. In this study, I chose lotus as the subject material of textile design development. And my intention for this study is to reflect Korean traditional cultural value as much as I can, and to develop textile design of Korean images by adding modern scenes. Also, I intend to print them on fabric, and apply them to cultural merchandise including scarves and ties, by using digital textile printing systems. The reasons for doing so, are to create high added value, and to let other peoples of the world, know about our excellent culture.

The purpose of my study is to provide some information on clothing for the handicapped with special needs. So I have designed clothes for the handicapped to provide some solutions for their clothing problems. These clothing designs for crutch and wheelchair users were based on solutions proposed by many researchers. The number of handicapped has been increasing gradually for years, especially the physically handicapped. Although they make use of many instruments for ease of movements and other physical conditions, most of the handicapped generally use crutches and wheelchairs. So I designed clothing for the crutch and wheelchair users. In order to ease problems in dressing and undressing, when using the crutch and wheelchair, various physical attributes of clothing should be considered: (1) Selection of fabric, (2) construction and location of the opening, (3) type and location of fastenings, and (4) design of garments for comfort and ease of movement. Clothing should also be able to satisfy psychological needs related to attractive appearance. My designs have proposed seven items of clothing. These include a cape-coat, over-blouse, one-piece dress and an pants for the crutch users. Also, a shirts, pants, and wheelchair wrap for wheelchair users will be displayed.

This paper presents an estimating method for local property changes and failure prediction of composite materials experiencing large shear deformation during draping process. The bone plate for the metaphyseal femur fracture was chosen to apply the presented method because it has complex geometry. The local property changes due to macro-/microscopic deformations of fabric composites during draping process were evaluated by various tests and the result was applied to predict static/fatigue behaviors of the bone plate. This paper was expected to present useful information on the design of composite structures with complex geometry and their performance evaluation.

The purpose of this study is to analyze the relationship among subjective textures, sensibilities and objective handle of knit fabrics and to provide useful information in planning and designing knit fabrics. We made 20 plain knit fabrics, as specimens, with a combination of 5 kinds of wool/rayon fiber contents and 4 kinds of stitch loop length. For the subjective evaluation, we used 29 questions of subjective textures and sensibilities and employed statistical analysis tools such as factor, Pearson's correlation analysis. An objective handle was measured by Kawabata evaluation system and HV and THV was calculated by KN-402-KT and KN-301-winter. The analysis of a Pearson's correlation with objective properties and handles and structural properties of knit fabrics demonstrated a highly linear relationship. Especially, wool/rayon contents and WT of tensile properties and loop stitch length and G of shear properties showed a correlation coefficient over 0.9. But a relationship of objective properties and subjective textures and sensibilities was non-linear and a linear multi-regression analysis showed that a objective handle had a lower prediction power in the area of subjective textures and sensibilities.

This paper presents a system level architecture evaluation technique that leverages transaction level modeling but also significantly extends it to the realm of system level performance evaluation. A major issue lies with the modeling effort. To reduce the modeling effort the proposed technique develops the concept of worst case scenarios. Since the memory controller is often found to be an important component that critically affects the system performance and thus needs optimization, the paper further addresses how to evaluate and optimize the memory controllers, focusing on the test environment and the methodology. The paper also presents an industrial case study using a real state-of-the-art design. In the case study, it is reported that the proposed technique has helped successfully find the performance bottleneck and provide appropriate feedback on time.

Yunnan, where twenty-six minor ethnics live, is located in Southwest part of China. They have preserved and developed their folk costume, artcraft, music and dance in their peculiar way with natural and cultural surroundings. So, Yunnan is known as a living folk museum. It's worth examining how climate and circumstances change has affected certain differences of dress shape in same ethnic. Research into costumes of minor ethnics can contribute to the study of origin of the trousers, as this group of people have well succeeded the basic form of trousers through their cultural history and everyday life. This study, at first, investigates geographical surroundings of each minor ethnic group, and figures out the style of all trousers by measuring the each size, then compares design color pattern and fabric. The origin of trousers examined by formative characteristics has been classified and comparatively studied. The study materials are twenty-three trousers selected from in Yunnan Folk Museum as well as other relevant literature records. This study suggests that one can examine the type of human culture through the forms of costume which reflects folk custom geography economy etc. This, in turn, can be used as a basic information for other studies, and in particular, for the study of origin and structure of the trousers.

For the structural firefighting protective clothing, it can show a synergy effect when it satisfies smart fabric to block off a harmful environmental element and ergonomics design that apply range of motion of human body and appropriate size system. There are various standards about the structural firefighting protective clothing, but it's difficult to find a rule about movement suitability because the performance of the material holds a lot of the rules. Therefore, the purpose of this study is to propose a scheme to evaluate the current structural firefighting protective clothing and to improve movement suitability by research on the actual condition. For this, the survey about wearer acceptability scale on design and size and about improvement requirements was executed gathering firefighters' opinion. Questionnaire was composed with 23 items about satisfaction on current structural firefighting protective clothing, body suitability, movement suitability, improvement requirement and subjective information. As a results, Korean firefighters demand ergonomics design of structural firefighting protective clothing which to minimize restriction of body movement and to maximize body suitability.

We use both theoretical analysis and simulations to study the impact of crosspoint-queued (CQ) buffer size on CQ switch throughput and delay performance under different traffic models, input loads, and scheduling algorithms. In this paper, we present the following. 1) We prove the stability of CQ switch using any work-conserving scheduling algorithm. 2) We present an exact closed-form formula for the CQ switch throughput and a non-closed-form but convergent formula for its delay using static non-work-conserving random scheduling algorithms with any given buffer size under independent Bernoulli traffic. 3) We show that the above results can serve as a conservative guide on deciding the required buffer size in pure CQ switches using work-conserving algorithms such as the random scheduling, under independent Bernoulli traffic. 4) Furthermore, our simulation results under real-trace traffic show that simple round-robin and random work-conserving algorithms can achieve quite good throughput and delay performance with a feasible crosspoint buffer size. Our work reveals the impact of buffer size on the CQ switch performance and provides a theoretical guide on designing the buffer size in pure CQ switch, which is an important step toward building ultra-high-speed switch fabrics.
