  • The efficiency tests of automatic positioning transmitter (APT) using satellite on life jacket were carried out to minimize casualties of fishermen and to make system optimization for effective SAR (Search and Rescue) operation. As the result of the tests, average position was equaled on the comparison between SPOT using low earth orbit satellite and DGPS (Differential Global Positining System), but standard deviation of DGPS for latitude and longitude were 66.4% and 46.3% smaller than those of SPOT. The position precision of SPOT was almost two times lower than LGT using geostationary satellite to compare 95% circular error probability. However, the success rate of receiver for SPOT was revealed as 86.5~94.1% on the experiments in the South Sea and the West Sea and it was 4.5 times higher than LGT. Therefore, SPOT is expected to contribute greatly to the rapid rescue of victim.

  • 일반적으로 구명조끼는 수상에서 위급한 상황에 처한 사람이 착용하여 물에 빠지지 않고 수면 위로 부상할 수 있도록 하는 것으로 구명조끼는 단순히 가라앉지 않도록 하는 역할을 할 뿐, 위급한 상황에 처한 조난지가 조기에 구출될 수 있도록 적극적인 도움을 주지 못한다. 이러한 문제점을 해결하기 위해 조난자가 위급 상황 시에 자동으로 조난신호가 발생하는 장치를 개발하였다. 조난자가 수중에 잠시면 자동으로 조난신호 발생장치가 구명조끼와 분리되어 위치값과 등의 정보를 무선으로 전송하고 LED 광을 이용한 구조신호를 보낼 수 있게 하였다. 실험결과 물속에 잠기면 자동으로 구명조끼와 조난신호 발생장치가 분리되었고, GPS에 수신된 위치의 좌표값이 무선전송되는 결과를 확인하였다. 이를 활용하면 조난자나 실종자의 위치를 파악할 수 있어 위급 상황 시 신속하게 대체할 수 있다

  • All kinds of art are the creatures of the daly and reflect the society and the life of the day in literary works. So, in which literary works, we can find the styles of those who lived in the specified days. And the styles of its character's costume are expressed with the day'mood and cultural backgrounds. In this study, we studied on the general meaning, which was shown in the Costume of early Ch'ing Dynasty that was forming the Costume of dress through dividing into the underwear and the outer garment in $\ulcorner$Dream of the read Chamber$\lrcorner$. During the Ch'ing Dynasty, according to the rule : Men followed it but women not" , they held on to the costume of them (both the Man and the Han) with a high pressure and a conciliatory policy. As a result, I have known that there is the Soojean clothe(수전의), which is the late Myung Dynasty's one and their is also Skirt (군), which held on the Costume of the Myung's. Hence in the Ch'ing , there are a lot of difference in the Costume , the economy and the politic because the ruler was not the han but the Ch'ing. Those characters are as follows. first, on the side of the style , it is occured in the coat and the over jacket of the round neckline. The style of the sleeves are also the tightly(고착). Second, on the side o f the material, the use of the furs are found. It seems that are influence of the north area. Third, it is involved not the traditional Costume of the Han, but the over jacket(which is waistlength), These characters had taken root into the Costume of the Ch'ing Dynasty. In case of the jacket, which are found in the novel most frequently , it was represented by the tight jacket (소오), the long jacket (대오), the short jacket(단오) and the Sam (삼). The skirt was used by women only. the Slacks were trousers only for men, so it was not foujnd in the women's wear. In the vest, the over jacket and coat, which are for putting on, its material, insiqnia and varied embroidery are very brillant and elaborate. The used materials are the silks , furs, wools and cottons. Among the dick silks are used most frequently . in case of the over jacket, the precious and varied furs are used for the collar, the sleeve or the decoration and the lining cloth. In the novel, mean followd the Costume of the Man and women followed the Costume of the Han. Especially, it is a special costume that there were women in male attire. Finally, the costume of the Ch'ing had built the unique one with holding on the advantage and the short point s of the northen race and the Han's.

  • This study develops a user centered outdoor jacket capable of energy harvesting based on consumer needs. Jackets are designed for typical outdoor activities such as hiking, trekking, and climbing, integrated with an energy harvesting module that can generate electric power from arm swing in outdoor and daily life walking. Textile based energy generators developed by the previous research of Lee & Roh (2018) were used. A prototype was created based on the arm swing motion experiment for location options and energy harvesting system functions, the simulation by the design sketch, and evaluation of the wearing test by experts. In-depth interviews were later conducted for the prototype with 10 outdoor experts to derive the optimal location of an energy harvesting system in three ways, and the prototype was revised to 5 styles that reflected reviews by experts on function and appearance. Research indicated that the energy harvesting jacket design signifies a user-centered design based on expert interviews and usability evaluation as well as previous research on energy generation and storage device. The jacket is convenient because it combines an energy generator in an optimal position to maximize energy generation with a storage and charging device that can be inserted into various position options for accessibility.

  • Textile The purpose of this research is to develop the design for activation of women s hanbok focused on functionality and convenience as well as on keeping the traditional beauty, and then to produce them. As a result of these explorations, I have reached conclusions as follows. first, the transformation of jackets and skirts are mainly limited to partial change in elements of the dress design-width and length of a jacket string and the upper strip on the outside of a jacket, change in width, and granting of symbolic meaning. Second, aesthetic features and formative beauty of traditional hanbok that the harmonization of mainstream colors and highlighting colors and curved silhouettes evoke were mental by products created as our people wished to become friendly to and to harmonize with nature. Third, grounded upon study of lines form and survey on brands, I have developed designs that maintain hanbok’superiority and at the same time incorporate functionality and convenience to fit modern life. I believe that the outcome of these of these explorations will contribute greatly to carrying the traditional beauty of Korean dresses to the maximun, and to developing and popularizing functional and practical living-fitted Korean dresses.

  • In this study, we provided examples of light emitting diodes (LEDS) in everyday sportswear and confirmed their usefulness to provide functionality, aesthetics, and entertainment. One type of sports jacket and one set of sportswear were designed and manufactured using LEDs and made available to the general public for use in daily life to provide functionality, aesthetics, and entertainment. To generate digital images, a textural design of a circuit image was developed and applied, and the LEDs were placed on the developed textile in an attempt to merge the LEDs with the design. The product was equipped with a tilt sensor and produced a randomly lighted jacket with LEDs that adjusted according to movement. The LEDs turned on in the desired location by lifting the arm during night sports activities. The tricolor of NEO PIXEL LEDs lit randomly and its rhythmical design could be maximized when moving or exercising outdoors, and also for entertainment. The role of creating interest for lively and unexpected pleasures and the aesthetic beauty of LED lights were also obtained. There was no inconvenience or restriction of movement by LEDs or internal structures using the hot-melting technique, and the removable attachment of the device made it easier to wash.
