This research is done to design and manufacture prototype clean room garments to improve the product yield of the clean room processing. To assist the research, other papers and references on the same subject were collected for analysis. Also the researcher made interviews with the workers at the clean room. The prototype garments made for this project was compared against the commercially available clean room garments used in the industry. A set of test was conducted to measure particle release from the garments. The prototype clean room garments was manufactured after having considered all the aspects stated above, and tested for the level of particle release. The test subjects performed 4 different movements(marching, arms stretch, squat and rise, and jogging) while wearing the prototype garments and commercially available clean room garments. Particle counts produced by each movement were measured. The data collected was statistically analyzed. The followings are the result of the test. 1) Overall, the prototype garments yielded less particle release.(p<0.001) 2) It showed greatest difference of particle counts for jogging(p<0.001) and squat and rise(p<0.001). In the arms stretch test. the prototype garments was also more effective in controling the particle, however, in the marching test. no significant difference was detected. 3) The prototype garments had less particle release in upper(p<0.001), middle(p< 0.001), and lower level(p<0.01) than the commercially available clean room garments. Manufacturing a new fabric for the clean room processing is important, but this research proves that the design of the clean room garments also determines the efficiency garments in the particle control. Therefore the same fabric can perform differently according to how it is designed. Improving the design will also improve the 7article control and reduce the cost of research. Eventually, the manufacturers will increase the product yield.

This study evaluated the preference and wearing characteristics of existing fitness compression wear for elderly women and identified the problems and improvements of existing fitness apparel. Preference and wearing characteristics for 6 types (A-F) of upper and lower fitness compression wear were evaluated. Photos and drawings as well as the preferred designs and details were investigated after presenting the evaluation clothing. Evaluations were made on a 5 point Likert scale for the fitness, allowance, pressure, ease of movement, fabric material, and overall satisfaction after wearing. The design preference indicated that B type (26.6%) and C type (23.4%) were preferred in the top with C, E and F type preferred to the same ratio of 19.4% in the slacks. The fitness and allowance amount of the top B type were the most appropriate (${\geq}4$), the C type was in close contact (2.86), and the F type was inadequate in the neck circumference (1.77). The feeling of pressure was high in the waist, abdomen, thighs, and knees. The area where the elderly people want to improve their strength was the legs; in addition, a pattern design was needed to strengthen leg muscles when designing fitness compression wear. However, a design with excessive adhesion due to a muscle support band was shown to be not preferred. Therefore, depending on the activity, it is necessary to develop a fitness compression wear that applies an optimum stretching ratio of fabric based on body surface area changes.

This paper presents a comparison of communication performance between the reconfigurable beam-steering antenna and the omni-directional (loop) antenna during standstill and walking motion. Both omni-directional and reconfigurable antennas were manufactured on the same fabric (${\varepsilon}_r=1.35$, $tqn{\delta}=0.02$) substrate and operated around 5 GHz band. The reconfigurable antenna was designed to steer the beam directions. To implement the beam-steering capability, the antenna used two PIN diodes. The measured peak gains were 5.9-6.6 dBi and the overall half power beam width (HPBW) was $102^{\circ}$. In order to compare the communication efficiency, both the bit error rate (BER) and the signal-to-noise ratio (SNR) were measured using a GNU Radio Companion software tool and user software radio peripheral (USRP) devices. The measurement were performed when both antennas were standstill and walking motion in an antenna chamber as well as in a smart home environment. From these results, the performances of the reconfigurable beam steering antenna outperformed that of the loop antenna. In addition, in terms of communication efficiencies, in an antenna chamber was better than in a smart home environment. In terms of movement of antennas, standstill state has better results than walking motion state.

A precise understanding of the human form in static pose serves as the basis of designing clothing. When the human body is in motion, however, even an article of clothing designed to fit the human form in static pose can pull and change, thus restricting the body. In order to increase the fit of the clothing, which may be termed the second skin, its form and measurements therefore must be determined in correlation not only with the formal characteristics of the human body, in static pose but also with its functional characteristics in motion, as caused by the movements of the human body. In this study, the motion factor was selected as the primary basis for designing slacks with good fit in both static and moving states. By indentifying the areas in which lower limb movement cause significant changes in body surface lines, we suggest several application methods for designing slacks. Using unmarried female university students aged 18 - 24 as subjects, a total of 32 body surface categories (15 body surface lines and 17 body surface segment lines) were measured in one static and 9 movement poses. In particular, expansion and contraction levels and rates were measured and used in the analysis. The analysis first involved the calculation of the average measurement per body part in body surface line in static pose as well as of the average expansion and contraction levels and rates in 9 lower limb movements. Two-way MANOVA and multiple comparison analysis (Tukey) were conducted on movements and individual somatotypes regarding measurement per body part and expansion and contraction rates. Body parts whose measurements of body surface lines differed significantly in body surface line in static pose versus in movement were then identified. The results of this study are as follows. First, changes in body surface lines caused by lower limb movements were significant in all body surface lines of the lower trunk, both horizontal and vertical, with the exception of abdomen girth, midway thigh girth, ankle girth, hip length, and posterior knee girth. Second, significantly expanded 10 body surface lines in moving pose were detected and illustrated in table 4. These body parts should be studied in designing or pattern designing, especially for close-fitting pants, in using stretch fabric, and in sensory evaluation of good fit during movement.

This study provided basic data to develop functional and fitness cycling wear for cyclists. We analyzed the domestic and overseas cycling wear brand patterns for tops and tights as well as compared pads attached to tights. The results were as follows. The tops of the cycling wear were designed with cutting lines in the lateral or yoke in the back to reflect cycling posture. It is necessary to study if there is a difference in the air resistance or fitness of the athlete. The sleeve hem band affected by arm movement during cycling, proper sewing and band pressure are also important. The tights have a brand that does not insert a band in front of the waist in consideration of the cyclist's breathing. It should take into account methods of constructing a proper garment pressure that does not interfere with cycling. Analyzing the cycling pad indicated that the three-dimensional shape and size of the pad show many differences for each brand, indicating a difference in cycling movement suitability. In addition, many of the cutting lines should account for the productive aspects because of the high consumption of the fabric in order to design a pattern considering the cycling posture.

The purpose of this study is to identify women (aged from 49~59), who have recently emerged as consumers, and their clothing preferences, and it suggests how to make jackets provide better fit and wearability. The results of the study are as follows. In drafting a pattern for size 66 tailored collar jacket with an X-silhouette, it was made with front waist length measuring B/4+1.5 cm, a back length of B/4+1.3 cm, an armhole depth of B/4, a hip ease of H/4+1.2 cm and a sleeve opening of 34.5 cm, to allow for easy movement. In drafting a size 66 high neck collar jacket, it was made with a front and back waist length measuring B/4+1.5 cm, an armhole depth of B/4, a hip ease of H/4+1.2 cm and a sleeve opening of 35 cm. In drafting a size 66 sports collar jacket with an A-silhouette, it was made with front and back waist lengths measuring B/4+1.5 cm, an armhole depth of B/4, and a side dart of 1.3 cm, to provide raglan sleeves. The last experimental jacket pattern improved the appearance and moving fitness evaluation especially for shoulder and arm movement. Based on analysis, jackets were made and subjected to an appearance evaluation using multi-modules to test the level of wearing satisfaction for each fabric and silhouette. the results of the multi-module wearing tests indicate that the preferred silhouettes caused less stressful situations in terms of both psychological and physiological signals.

String, as clothing material, has played a functional, symbolic and decorative role in garment traditionally. The string has a shape of continuous line, which is one of the basic elements for the design: points, lines and sides. It can effectively represent the silhouette by making our vision flow to a certain direction. This study reinterprets the traditional form of string in a new modern way by developing "Tube-Shaped String" which has an empty hole in the middle. As a creative attempt, the new tube-shaped string can be used for fashion design by applying it to unique shapes, colors, textures, and draping expressions. In a role dimension, this string can become the main fabric material. The methods of the study are as follows. First, it examines the traditional shape and role of string in the history of garment. Second, it studies modern designers, such as Christian Dior, Ann Demeulemeester, Dolce & Gabbana, and 3.1 Phillip Lim, who have applied the string to their design, and have explored the various potentials of the string in the past four years. Finally, based on the theoretical research and practical analysis, this study creates a new tube-shaped string, applying its own technique to fabricating three garments: jacket, dress, and body suit. As a result, each garment shows unique silhouettes, rich texture and color, and rhythmical movement. The unique silhouettes reflect the shape and movement of different bodies. The texture and color are created through the shades of the string which come from the overlapping strips. The garments come with an unbeatable aesthetic design compared to conventional uniform design. As a new material in clothing, this tube-shaped string can be developed to satisfy the public, which has widely varying tastes in fashion.

This paper explores the possibility, and suggests an experimental procedure, of industrial application of traditional textile design techniques, such as hand silkprinting and natural dyeing. Theoretical and traditional background of this study is William Morris and his followers' Arts and Crafts Movement from the late 19th century to the early 20th century, which laid the philosophical as well as technical foundations of modern textile design tradition. Based on the basic understanding of the design philosophy, and starting from the design techniques of Morris and his successors, I made some experimental and systematic color plans reflecting and exploiting the physical traits and structure of jacquard woven silk material fabrics. And I applied hand silkscreen printing techniques on the jacquard silk fabrics of my own making, while testing various color combinations of natural dyes. After finishing final processing of design samples, I could get textile design products which met the criteria of my original expectation, i.e., eco-friendly and aesthetic design samples that can also be produced in automatized mass production system of contemporary textile industry. The conclusion of this experimental study is that I can expect the natural dyeing techniques, jacquard silk fabrics design techniques, silkprinting techniques, and the basic processes used in this study to be safely applied for contemporary commercial textile industry utilizing automatized silkscreen printing system and digital printing devices.

The purpose of this study was to investigate the present condition of cold protective clothing for mailman, to improve its design in movement, fitness, and other functions, and supply basic data for its performance evaluation. The results are as follows : The 46.60% of those questioned did not satisfy current clod protective clothing fer mailman. Especially, they considered dissatisfactory in properties such as waterproof, comfort, activity, and sweat absorption. The newly developed cold protective clothing is two-piece style composed of jacket and pants. Both jacket and pants are composed of inner and outer clothing individually. In both jacket and pants, their outer clothing's material was waterproof, windproof, and breathable shell fabric on which PTFE film laminated and their inner clothing's material was 100% polyester Polar polis to have better insulation property. The jacket has attachable cap which can be used as rain gear and set-in sleeve with stand collar. It also had big outside patch pockets and side seam pockets to ensure enough storage space. The pants have knee pads to give free movement to knees and slant side pockets. Inner clothing of both jacket and pants can be worn during working inside without out clothing. Insulation of the newly developed cold protective clothing was not better than current one except right hand, left hand and left foo. It is considered that is because thickness of material is the most important factor to influence insulation.

This study was initiated to develop a uniform design suitable for child inpatients. The experimental hospital inpatient uniform design was developed based on the results of the prior studies. The panel was composed of 5 experienced nurses and 5 clothing specialists. They evaluated the function of the experimental inpatient uniforms developed in this study. The experimental hospital gown design was reformed based on the panel's evaluation.1'hen the child inpatients performed the wear test for the reformed experimental hospital gown. The results of the study are as follows; 1. The child inpatient hospital gown design of the most hospitals were similar to the adult patient's uniform : the V-neckline shirts with full length set-in sleeves. The bottom was full length pull-on pants. The fabric was white cotton with blue hospital logo and stripe print in most cases. 2. The panel's specialty affected the evaluation of the uniform design. The nurses concerned about the durability after washing and ease for medical treatment. The clothing specialists cared about the features related to the clothing construction and ease for physical movement of body. 3. The most preferred hospital inpatient uniform design by the panels was the shirts or one- piece gown with three-quarter length sleeve and overarm seam opening. 4. The researchers developed one-piece dress gown for the children under two years old. Three different size pajamas were developed for children 2∼5 years old,5∼8 years and 8∼12 years old.
