This study developed a method of calculating dynamic wearing ease (DWE) to make patterns for coverall work clothing. The DWE was measured from 3D body scan data of women in their 20's (n = 10). The body postures adopted for measuring the DWE were sitting and deep bending postures. Three types of experimental patterns (A, B, C) were developed. The DWE was applied at the waist and hip lines of the pattern. The location and size of the DWE varied from one pattern to another. For pattern B, DWE of 8.8cm was applied at the back of the waistline. For pattern C, 5.3cm was applied at the waist for the center back line, and 3.5cm was applied at the under hip level. The comfort of the experimental clothing was evaluated in six body postures. The results showed that patterns B and C were comfortable at the crotch, shoulders, and arm pits. Pattern C was comfortable at the hip and crotch areas in the arms lifting-up posture and the stepping-up posture. The appearance and fit of the experimental clothing were evaluated by the panels. Patterns B and C fitted better than pattern A at the abdomen. The results suggest that DWE should be applied at the waist and hip levels for making coverall work clothing patterns.

This study develops a coverall design for the body shape and movement of infants. This research analyzed these processes: 1. The current coverall styles preferred for infants. 2. The appropriate products for the real size, body shape, movement, and fit of infants. 3. The observations of the 6 months to 9 months movement and development of infants. 4. The design and creation of a new coverall base in this study, and to check the suitable test the developed coverall design for the infant. The result of this study are: A coverall for infants that lie or crawl on the floor must avoid opening in the center front and a gore has to be added at the crotch of the pants for the better movement of infants. These ways provide infants a neat appearance and easy movement. The test of developed designs shows that the developed coverall design covers the size gap of the trunk loop according to the growth of the infant and the movement of the legs; in addition it provides a positive aesthetic effect. The waistline in the developed coverall (a waistline that should exist lower than the body waistline of the infant) can reduce seam stress because the pressure of the seam line can be absorbed in a dipper. It is one of the suitable design points for infants lying prone all day long in this study.

It is essential to consider the heavy industrial working environment factors which are regarded as harmful to workers' health and safety and suitable work motion factors for the workers' motion while developing the work clothes for painting workers in the machinery and shipbuilding industries. This study suggests the use of 3D virtual clothing simulations as a solution to protect the human body from hazardous working conditions accompanying the development of painting work clothes and assessing the work motion performance associated with the comfort while workers wear them during the work clothes. The initial aim of the study is to examine a male avatar to run work motions simultaneously within a 3D virtual clothing simulator, secondly, to present the simulation images of coverall type men's painting work clothes with the application of two experimental painting work motions and one control motion to the avatar, and finally, to present the distance analysis images of the painting work clothes and the avatar body and air gap rates through the analysis of cross-sections of the avatar body while wearing the coverall work clothes according to the work motions. The results showed that the distance degree of painting work clothes to the avatar body for each part of the human body when performing painting work motions. Moreover, 3D virtual clothing simulations enabled the creation of a male model avatar to run painting work motions together and the painting work clothes developed were found to be suitable for the painting work motions.

The purpose of this study was to provide information on how to improve the current sizing system of infant coveralls through analysis of the present system. In order to compile the information about dissatisfaction with the appropriateness of the fit of infant coveralls, a questionnaire was administered to mothers of 241 infants (aged under 36 months) living in Seoul, and analyzed using the SPSS WIN.10.0 program. Also, the manufacturers'basic body sizes were investigated. The results of this study were as follows : 1. The results of the comparison between the manufacturers'basic body sizes and the body measurement values obtained as the physical standard of the nation(1997) show that in terms of length and hip circumference, the manufacturers'body sizes were larger. On the other hand, in the waist circumference, the manufacturers'body sizes were smaller than the national average. 2. Research on the production sizing system of domestic and international brands, showed that the sizing interval of domestic brands were 6 months, whereas the international brands were 3 months f3r infants under 12 months. 3. Concerning fit, the areas causing most dissatisfaction were: the trunk length, sleeve length, inside leg length, and neck depth. The results showed that dissatisfaction with the suitability of the sizing of current infant coveralls according to the body part differed among the groups according to the month of age.

Disposable protective coveralls that cover the entire face and body are essential for operations in contaminative or dangerous environments. This research studied disposable protective coveralls on Korean market in order to improve the products that agricultural workers wear. We investigated the size specifications of 22 disposable protective coverall products sold in Korean markets and analyzed how well the size specifications cover Koreans' sizes by comparing and analyzing the size specifications with Korean body measurements and Korean standards for protective clothing. We analyzed the consistency, regularity, and fitness to body measurements of Koreans for each size by measuring the sizes of 15 different parts for 22 products each. Current disposable protective coverall products for the Korean market are unsuitable for Korean body measurements, especially women's. It was expected that wearers would be unable to choose products that fit their bodies well just by the offered size specifications due to a lack of regularity between the measurements for each size. In this result, it was assumed that the development of KS standards and the coverall pattern that reflect the body measurements of Koreans are needed.

The physical responses and subjective sensations of different cleanroom garments were compared in order to discover which cleanroom garment design could minimize pollution of the working environment by dust from the worker, maintain a pleasant microclimate and provide effective thermoregulation. A. Coverall with non-detachable hood, kimono sleeves (front), raglan sleeves (back), raschell net on the bodice B. Coverall with detachable hood, kimono sleeves (front), raglan sleeves (back), raschell net on the bodice C. Separate top with non-detachable hood, kimono sleeves (front), raglan sleeves (back), raschell net on the bodice D. Coverall with non-detachable hood, set-in sleeves, raschell net on the bodice E. Coverall with non-detachable hood, raglan sleeves (back), l00% cotton inner wear (upper body) The results of the experiment were as follows. Because the hood covered the shoulder and the chest areas, the chests temperature of the worker wearing garment E was quite higher than those wearing other garment designs. For fabric that has been coated in order to prevent dust, layered designs should be avoided in order to prevent skin temperature from rising. Compared with layers of underwear, it would be more effective to attach a see-through raschell net which clings to the body. Thermal sensations were also highest in garment E, reinforcing the finding that layered designs should be avoided. Through the experiment, it was found that a new material coverall with a non-detachable hood was effective in minimizing dust, suppressing skin temperature increases, maintaining a superior microclimate and providing pleasant subjective sensations.

스피커 시스템은 가청 주파수 대역 20 ~ 20,000 Hz를 하나의 유닛으로 재생하는 것이 이상적이지만, 물리적으로 구현하기 어렵다. 따라서 두 개 또는 그 이상의 유닛을 사용하고, 멀티웨이 시스템으로 구성하여 오디오 대역을 커버한다. 멀티웨이 스피커 시스템에서는 고음과 저음의 유닛이 정상적으로 동작되도록 크로스오버 네트워크 필터를 필수적으로 사용해야 한다. 네트워크 필터의 크로스오버 주파수는 대부분 1 ~ 4 kHz 대역에 존재하며, 이 대역은 명료도의 기여율이 높고 음질에 미치는 영향이 아주 크다. 그러나 여러 가지 원인 때문에 크로스오버 주파수 대역에서 위상과 진폭 특성이 정확하게 결합되지 않은 경우가 많다. 즉, 유닛 간의 거리 차와 전기적인 특성 차이 때문에 크로스오버 주파수에서 유닛 간의 진폭과 위상 특성이 정확하게 결합되지 않아서 주파수 특성이 불규칙해지고, 그 결과 음질이 좋지 않고 명료성도 나빠진다. 크로스오버 주파수에서 유닛들을 정확하게 결합시키기 위해서는 각 유닛의 진폭 특성뿐만 아니라 위상 특성까지도 고려하여 결합시켜야 한다. 본 논문에서는 유닛 간의 지연 시간을 조정하여 크로스오버 주파수에서 평탄한 주파수 특성이 되도록 하는 방법과 유닛들의 주파수 롤 오프 특성도 고려한 필터 선택 방법을 제안하였다. 그 결과 크로스오버 주파수 대역에서 ${\pm}1$ dB의 평탄한 주파수 특성이 얻어지고 명료성도 향상되었다.

화장품에서 색조 화장품 분야에서 분체의 함유율이 높은 투웨이케익, 팩트, 페이스파우더와 같은 파우더류 제품은 함유되는 분체의 물성이 품질에 큰 영향 인자로 작용하기 때문에 분체의 복합화, 금속비누 처리, 아미노산처리, 실리콘처리, 불소 처리등을 통한 품질 향상을 목적으로 표면처리가 시도되어 왔다. 위와 같은 파우더류 제품중에 투웨이케익은 커버력이 가장 요구되는 제품으로서 부착성이나 퍼짐성과 같은 부가품질의 동시 구현이 다른 파우더류 제품보다 어려우며, 화장을 두껍게 느끼거나 답답하다는 사용자들의 잠재불만도 존재하는 제품군이다. 본 연구는 투웨이케익 제품의 중요품질인 부착성과 퍼짐성을 향상시키고, 친화성을 충분히 고려한 새로운 표면처리 방법으로서 피부성분과 구조를 모사하여, 스킨케어에 주로 사용하는 성분들로 나노베시클을 제조하여 그 구조를 파괴하지 않은 상태로 표면 처리하는 방법에 대한 것이다. 분체를 제조하기 위해 먼저, 레시친, 세라마이드, 초산토코페롤, 부틸렌글리롤을 사용하여 고압.유화로 나노유화물을 제조하였고, 이것을 수상에 분산된 체질안료 분산액에 투입, 2가 금속염 용액을 투입한 후, 여과, 건조과정을 통해 나노베시클이 피복된 새로운 기능의 분체를 얻었다. 피복되는 공정에서는 금속염의 농도에 따라 피복량이 결정됨을 확인하였고, 피복된 파우더의 물성에서는 현재 주로 사용하는 실리콘 처리체질안료에 비해 본 연구를 통해 제조된 파우더의 마찰계수가 낮았으며, 외력에 의한 부착성 평가에서도 파우더의 이탈량이 적은 결과를 나타내었다. 또한 이를 함유한 투웨이케익과 함유하지 않은 투웨이케익의 평가에서도 같은 경향의 결과를 나타내었다.
