Protective clothing for firefighters typically consists of a flame resistant outer shell and inner layers. The inner layers are generally composed of a moisture barrier and a thermal barrier. On performing the task in fire place the heat and perspiration generated from the body become trapped inside the protective clothing. Those heat and moisture result into heat-stress and physical fatigue of fire fighter, which hinder the work. Therefore, the system of clothing designs and material layers must be chosen carefully to balance protection and comfort. 3 kinds of protective clothing of 3 layer structure were used in the experiment of physiological comfort. From the comparison of wear trials with the 3 kinds of layers in firefighters clothing, it indicates that the moisture dissipation of A+B2+C was highest, following A+BI+C andA+B3+C. And the heat dissipation of A+BI+C and A+B2+C were better than A+B3+C. In the protective clothing with A+B3+C, heat and perspiration generated through exercise remained in clothing system long and caused discomfort.

Since the air permeabilities are closely connected with clothing hygiene, air permeabilities required to optimize dressing were studied and measured the air permeabilities that take air layers among fabrics into account. The thickness of air layers were controlled from 3mm to 24mm, and the numbers of air layers were made from one layer to three layers. The samples used were selected in casual wears in spring and autumn. The results obtained are as follows; 1. Specific air permeabilities of superimposed fabrics decreased gradually according to the increase of superimposed number. 2. Specific air permeabilities of the same kind of fabrics increased at first and later decreased by the increase of intervals when the fabrics are superimposed at regular intervals, and those of the different kind of fabrics decreased. 3. Specific air permeabilities of the different kind of fabrics decreased to the 18mm of total thickness in air layers and increased later.

The Korean wintertime Onmapsi Campaign recommends wearing underwear, layered clothing, or thermal accessories in an indoor environment of a lower than room-heating condition. We surveyed 132 government officers, about Onmapsi wearing conditions and campaign satisfaction. The term was found to be unfamiliar to them, even if they wore underwear or thermal accessories as participants in the campaign for the wintertime office of low temperature 18-$20^{\circ}C$. They wore thick shirt/pants or cardigans/sweaters; however, underwear or thermal vests was worn relatively less. They wear 2.9 layers on top and 1.7 layers in bottom in average. They have their own methods to keep the body warm, which are using 1) functional thermal clothing, such as turtleneck shirts of heat technology new material, 2) functional thermal accessories, such as warmer and muffler, 3) functional office goods, such as a thermal computer mouse and blanket on the desk. The campaign requires more advertisement, a revision on the details of the proper wintertime indoor environment, and develops the varieties of Onmapsi apparel.

본 연구는 상변화물질의 농도가 의복내 공기충의 온도변화에 미치는 영향을 연구하고자 하였다. 상변화물질로는 노나데칸을 사용하였으며 농도는 아크릴 바인더 대비 10%, 20%, 30%로 조절하여 면직물에 코팅처리하였다. 동적 열전달 측정장치인 Human-Clothing-Environment Simulator을 사용하여 고온에서 저온 이동시 다시 고온이동시의 의복내 온도변화를 측정하였다. 외부 환경온도는 고온은 34도, 저온은 5도와 10도를 하였으며 먼저 34도에서 한시간 동안 컨디셔닝한 후에 5도 또는 10도에 30분 동안 노출시켜 의복내 온도변화를 측정하였고 다시 34도에 노출시켜 30분동안 의복내 공기층에서의 상변화물질의 열적거동을 살펴보았다. 그 결과 상변화물질처리된 직물로 이루어진 의복내 공기층은 고온에서 저온이동시 상변화물질의 발열효과로 인해 미처리 직물보다 높은 온도를 나타내었으며, 저온에서 고온이동시에는 흡열효과로 인해 미처리 직물보다 온도상승이 느리게 나타났다. 농도가 증가할수록 상변화물질에 의한 발열효과는 증가하는 것으로 나타났으며 흡열효과의 경우에는 20%에서 큰 변화를 갖는 것으로 나타났다. 농도변화에 따른 미처리와 처리직물 사이의 차이를 보면, 10%에서 20% 증가시에 나타난 차이가 20%에서 30% 농도변화시에 나타난 차이보다 크게 나타났다. PCM 처리된 모든 직물들이 상변화를 겪는 것은 아니었으며 직물층에 따라 상변화를 하였고 최외곽층의 경우에는 상변화물질에 의한 흡열발열현상외에도 외부로의 열손실을 겪기 때문에 이에 대한고찰이 있어야하는 것을 알 수 있었다.

The purpose of this study is to research on status of physical discomfort and clothing life including clothing inconvenience for enhancing self-reliance of elderly women, newly emerging consumer. The subject of research were 346 elderly women who aged 60 or older in Seoul and Seoul Suburbs. Survey consisted of questions about body discomfort, satisfaction and purchasing criteria of ready-to-wear, the inconvenience of clothing. The results of this study are as follows: Physical discomforts were generally associated with the ability to regulate body temperature. The biggest complaint of ready-to-wear was the price, and the next were the size and activity. In purchasing criteria, 'clothes to fit my body shape', 'clothes easy to put on and take off', 'comfortable clothes to work' showed high score. In clothing inconvenience, 'feel inconvenience due to several layers of clothing to avoid chilliness', 'feel heaviness in the waist due to tightness', 'feel chilliness even when wearing several layers of clothing in the winter' were the most uncomfortable parts. Subjects over the age of 80 years and needed the help of others in activities experienced more inconvenience in clothing life. It seems that body discomfort such as dulness of movement and loss of body temperature regulation capability due to aging had a influence on their clothing life. This problem could be improved by the adjustment of pattern allowance, the selection of the fastener, and the proper use of functional fabric. The results of this study will be used as a basis for development of the elderly women's clothing to increase convenience and mobility in everyday life.

From now, we've made a study of Korean Clothing about our Royal family's or high birth person's and made little of our plain folk's. Our traditional clothing is plain folk's clothing and that is our fundamental clothing, so plain folk's clothing has an important part in our life. In this point, first we were concerned about the plain folk woman's clothing in the plain folk's clothing and it consists of the way of ethnographic method like listening from the lod about their contant living wear-daily wear. This research covers the time from the end of the Yee-Dynasty to 1950's and the place, each province where the primitive dwellers still live and respondent's age range is about from 60 to 80. In the viwepoint of our climate and construction, women should be over-worn an underwear and they have worn the underwear for the purpose of their heating and the inflating of the skirt. The end of the Yee-Dynasty, high society person wore underwear 7-8 layers thick and also the sow society person wore it 3-4 layers thick. The Plain folk woman clothing's basic system is the skirt and Korean jacket and dari-sok-got, sok-sok-got, pants, dan-sok-got as an underwear, and Korean socks and Korean shoes(straw shoes) are added. This research discusses these clothing by dividing them into each part and enlighten the peculiarity, shape, cloth and how to construct and especially about the difficult-making Korean jacket, we handled the method of rough guess sizing. As the result, we found that each province had a similar peculiarity in the general clothing but they had a different cloth name and a wearing method. Especially, An-dong an Eum-sung, they'd worn their own traditional wear, sal-chang-hojaengiee. We made a good product of rough guess sizing data those have not been known.

The actual clothing conditions of male collegian were surveyed to analyse clothing contents and the rate of wearing underwear. Then, clothing microclimate, physiological responses, and subjective sensations were investigated through wearing trials on human body in climatic chamber based on the results from the survey. The results were follows: 1. Male collegian wore T-shirts, jeans, and socks in summer, and total clothing weight per body surface area was $561g/m^2$. The number of clothes for upper body were 1 layer, but the number of clothes for lower body were 2 layers. Subjective sensations have no significant difference with wearing underwear. 2. Most physiological responses including temperature inside clothing, mean skin temperature, skin temperature of chest, abdomen, thigh, and lower leg, and sweat rate, were higher in with-underwear than in without-underwear. But pulse rates were not significantly different between with-and without-underwear.

This study examines the preparation and characterization of Kenaf/Starch bio-composites used as filler and a matrix. Kenaf was cultivated in Chung-ju in Korea, and the Kenaf/Starch bio-composites were prepared under various conditions of kenaf fiber length (1-5 centimeters); the content of Kenaf fiber was 10%, 20%, 30%, and 40%, and the number of composite layers (one-four). Depending on the formation conditions of Kenaf/Starch composites, the physical properties such as tensile strength, elongation, and the young modulus of the Kenaf/Starch composites were measured. In addition, we measured the SEM cross-section images in order to investigate the interfacial adhesion properties of fractured surfaces. As a result, the tensile strength and elongation of the Kenaf/Starch composites were highest in the molding conditions of a hot press at $120^{\circ}C$, 3000PSI of pressure, and for 30 minute periods. The result of measuring the physical properties of the composites manufactured by varying the content of Kenaf fiber when the content of Kenaf fiber was 30% as well the physical properties of the Kenaf/Starch composite was found desirable. It was found that the physical properties improved with more overlapped layers in the composites manufactured by varying the number of overlapped layers. Through the measuring of the SEM cross-section images, we found that the interfacial adhesion state between the filler and matrix of Kenaf/Starch composite greatly affects the physical properties.
