The objective of this study is to analyze the characteristic of a functional design for a commercial outdoor brand jacket based on 3 types of functions : windproof, waterproof, and cold proof. To analyze the design and fabric characteristics of outdoor jackets by function, 903 men's and women's outdoor jacket images were selected from the catalogues during S/S 2009 - F/W 2011 of the 6 brands: The North Face, Columbia Sports Wear, Kolon Sports, K2, Arcteryx and Mont-Bell. These brands were selected based on their high market share and brand awareness of the outdoor brands in Korea. In this study, design elements analysis was conducted as following 8 elements: hood/collar height/central front flap/waistline/pocket location/ventilation for the body part/sleeve patterns/cuff for the sleeve part. Fabrics were analyzed by the frequency of fabric types used in the 3 jacket types. According to the result derived from the analysis of the six brands of outdoor wear jacket design trends by year, detachable hood and a co-use of velcro and elastic bands have been mainly designed for all of windproof, waterproof, and cold proof jacket to all in order to respond quickly to changes in the external environment. For reinforced storage function on trekking, the number of pockets has been gradually growing, and a function was being developed to connect an electronic device to a pocket. The method, result, and collateral observations relevant to each of these phases are described. Outdoor jacket design characteristics were investigated for outdoor brands, which can provide data to suggest more accurate functional design, and satisfy functional design needs. In this regard, this research was significant in the sense that it suggested preliminary data to reconsider competitiveness of the brand products.

This study aims to suggest the proper neck-width of slim-fit jackets according to numbers of jacket buttons from an one-button jacket to a four button jacket for men in their 30's. The researchers carried out both an appearance evaluation and a movement functionality evaluation. When analyzing the appearance evaluation, there were meaningful differences. The one-button jacket showed a high score on the back-neck width of +2.4cm. The two-button jacket and the three button jacket showed a high score on the back-neck width of +1.4cm. The four-button jacket showed a high score on the back-neck width of +0.4cm. The result of movement functionality evaluation was not related to the appearance evaluation, and showed no meaningful difference. The one-button jacket and two button jacket showed high scores on the back-neck width of +2.4cm. The three button jacket showed a high score on the back-neck width of +1.4cm. The four-button jacket showed a high score on the back-neck width of +0.4cm. In analyzing both results, the study suggests that the proper front neck-width and that of the back-neck width of +2.4cm be for the one-button jacket, the back-neck width of +1.4cm be for the two-button jacket and the three-button jacket, while the back-neck width of +0.4cm be for the four-button jacket.

This study aims to discuss the image making of K-pop girl groups to provide an outlook on the necessary fashion components in order to express certain concepts by analyzing the fashion styles. The fashion styles of the representative girl groups from 2007 to 2011 were classified into five types: retro style, schoolgirl style, chic style, sporty style and marine style. The following are the features and elements of image making by style. The retro style pursued going back to the past. It used stripes, dots, leopard patterns, spangles and denim. It reproduced the style of the past to the trendy style using big sunglasses, retro makeup, girlish hair and gold wigs. The schoolgirl style created the sexy or cute image by using school uniforms as the motif including shirts, short pants and knee socks. It included having natural makeup and straight hair and differentiated colors, patterns and designs. The chic style was classified into rock chic look and sexy look. Both looks had common elements including smoky pop active makeup while the fashion concepts and hair styles were different. The sporty style took the concept of cheer girls. It used plaid shirts, baseball jackets, short pants, thigh high boots, vivid hair accessories, romantic makeup and straight, wave hair. The marine style took the naval uniform as the motif. It expressed the image using short pants, stripe patterns, wappens, naval caps and smoky sexy makeup, straight hair.

The study will analyze the costumes of the Scythians tribes who lived in the region of Altai in the 3-5 century BC. The purpose of this study is to prepare new material to re-examine the theory, which claims that the origin of the circular motives of korean costumes are to be found in the typology of the Scythian costumes. In this study, we analyzed the most recent reports of archaeological excavation about the unearthed clothes in the Pazyryk region and compared its information with european literature. The conclusion of this study is as follows: The jackets of the Pazyryk region are classified in two types, (1) opened jacket with narrow sleeve and (2) enclosed jacket with narrow sleeve. Trousers were separated by (1) narrow and (2) extreme wide trousers. The enclosed jacket of tunic form and extreme wide trousers are newly excavated. It proves, there was a vivid exchange between the Scythians and their neighboring cultures. It can be noted, that there existed a diverse Scythian culture of costumes, besides the commonly known clothing culture of the "Pazyryk-rider". Based upon the results of the previous research, it can be said that the opened jacket with narrow sleeve and narrow trousers are costume typologies which are common for all Scythian tribes of the whole Eurasian region. The hem of the edge of jacket is proven to be a connective element, which is common to all Scythian tribes.

Concrete columns strengthening effect due to FRP (Fiber Reinforced Polymer) confinement depends on the elastic modulus of the FRP. This study analyzes the retrofitting effect of FRP confinements according to elastic modulus of FRPs using the existing data and suggests a practical model to assess the strengthening effect. This study subdivides the FRP elastic modulus into three parts based on normal concrete and steel elastic modulus. The slope and the y-axis intersection seem to increase with increasing FRP elastic modulus. In addition, the strengthening effect does not develop up to some amount of FRP confinement having relatively smaller elastic modulus than the compressive elastic modulus of concrete. In this case, a linear model to assess the strengthening effect is hard to be used. Thus, this study suggests that the FRP jackets having 2 times larger elastic modulus than that of concrete are recommended to be used for retrofit of concrete and that a linear model can be applied for the case. The suggested model shows nearly the same result regardless to the restraint of the y-axis intersection. This has been observed at the model of steel confinement and, thus, is a reliable result.

The purpose of this study is to analyze present the pattern making of the lining fabrics calculating the right ease and rising quantities of arm-hole when the pattern of the lining fabrics of stretchable jacket fabrics is produced. The outcomes of this study are as follows. The right ease of lining fabrics was not room of 0cm as patterns being same the right side of fabrics in the girth of the chest, waist, and the edge of a garment and gets the most excellent valuation, and then the girth of the chest, and waist was applied to 2cm and around the edge of a garment 0cm in regular lining fabrics. In addition to, although the ease of patterns of the lining fabrics was more, it was not necessarily to satisfy. The result of the valuation according to the quantities of rising arm-hole of the pattern of the lining fabrics showed that the making lining fabrics that the quantities of rising arm-hole was 0.8cm in the body and 1.2cm in the sleeve in the both the stretchable fabrics and regular lining fabrics was the most excellent thing, and then 0cm in the body and 2cm in the sleeve, and then 0cm in the body and 0cm in the sleeve. The valuation of external appearance on the quantities of rising arm-hole was recognized similarly because of being rarely significance level, but around the chest and waist was recognized as being significance level in wearing satisfaction.

The modernization of the fashion design in our country, like our chaotic modern history, has not been easy for us to grasp its main stream because it lacked historical consciousness and sincere attitude of creating. In trying to find out designs very Korean, designers usually ignore the deeply rooted ideologies and modes of our own, and primarily depend on the scattered fragments of tradition, such as the curled line of the ancient roofs, folk jackets and skirts, and Talcum, our ethnic dance, sometimes making some patchwork like clothes they divan't really intend to make. In the world of modern design, especially of the fashion industrial design, designs more scientific, more rationale and more positively appealing to the consumers, not the unconscious and emotional ones, are being demanded. To win in the fierce competing world of design as well call this age an age of "Design War", it is desirable for us to create our peculiar designs by uniting the internationalism (universality) and nationalism (traditionalism) together under a single rigid purpose. Analyzing the designs mainly of Korean style fashion designers since the 1980s, 1 could see that Korean designs in the aspect of appearance have a strong tendency toward applying or reviving the traditional elements, thus are under a bias toward nationalism rather than in ternationalism. The idea of "very Korean" does not mean a mere harmony or negotiation of the traditional elements with modern ones. It is rather a concept from vivid historical experiences of the conflict between the purely Korean mental, cultural heritages and the demands in mod- eradiation. Therefore, based on this concept of "very Korean" we must create fashions completely Korean and modern at the same time.n and modern at the same time.

This study analyzes the efficiency of a solar cell attached to an air circulation jacket. A commercially available silicon solar panel was selected and attached at four spots where the body angle was $40-60^{\circ}$ and voltage ($V_{oc}$, V), current ($I_{sc}$, A), and output power (P, W) were measured to determine the efficiency. The solar panel was applied to the outer jacket that operates with two fans to increase the convection that lowers the body temperature. The heavy work of standing, walking, and sweeping of a street sweeper was simulated in the field test. The microclimate within the jacket (with or without a fan) was measured and the subjective thermal, humidity, and comfort sensations were surveyed. SPSS 12.0 statistical package was used for a t-test and Wilcoxon signed-rank test. The results show that the highest efficiency of the solar cell was at the incident angle of $60^{\circ}$ in terms of voltage, current and output power distribution. The microclimate temperature of the air circulation jacket decreased significantly with the high power of the fan and subjects felt cooler than the jacket with a fan at the incident angle of $60^{\circ}$. Air circulation jackets operated by a silicon solar panel showed a significant cooling effect on the wearers.
