국내 인터넷 사이트의 60% 이상은 회원가입시 본인확인 등을 위해 주민번호를 수집?저장하고 있다. 인터넷 사이트의 주민번호 수집 목적은 개인식별(중복가입여부 확인)과 본인확인, 연령확인, 마케팅 활용을 들 수 있다. 그러나 인터넷 사업자들의 주민번호 수집이 증가하면서 개인정보 유?노출로 인한 피해도 늘고 있다. 인터넷 사이트에서 주민번호 수집을 제한하면서 주민번호 기능을 제공?유지하기 위해 마련된 것이 주민번호 대체수단(i-PIN)이다. 본인확인기관이라는 다수의 제3의 신뢰기관이 인터넷 이용자의 개인정보를 받아 저장하고 인터넷 사이트 가입 등 필요할 때, 인증을 해주는 방식이다. i-PIN 서비스의 구성요소와 기능, 제공 서비스 등 i-PIN 서비스 프레임워크를 설명하고, 복수의 본인확인기관이 이용자의 인증을 위해 주고받아야 하는 메시지의 종류와 형식, 방법에 대한 국내 기술표준을 소개한다. 또한 중복가입 확인이 필요한 인터넷 사이트를 위해 유일 식별값으로 사용되는 중복가입확인정보 생성방법과 메시지 교류 방법 등을 소개함으로써 인터넷 사이트가 주민번호 대체수단으로서 타 수단과 차별화된 전략을 소개한다.

금융보안 OTP를 이용한 온라인 본인확인 방안에 대한 연구

정찬주(Chan-Joo Chung),김승주(Seung-Joo Kim),원동호(Dong-Ho Won) 한국정보보호학회 2008 情報保護學會誌 Vol.18 No.5

본 논문에서는 금융보안 OTP를 이용한 온라인 본인확인 방안을 제안한다. 현재 국내에서 신원확인 방식으로는 공인인증서를 이용한 전자서명, 휴대폰SMS 발송번호, 신용카드정보 및 금융계좌정보 인증방식을 활용한 본인확인 방식이 사용되고 있다. 하지만, 공인인증서를 이용한 전자서명 방식이외의 방식은 명의도용된 휴대폰을 통한 본인확인과 신용카드 비밀번호 앞2자리 및 금융계좌의 비밀번호 4자리 입력 등 민감한 정보의 노출 위협 등의 문제점이 있다. 본 논문에서는 이와 같은 문제를 금융보안 OTP를 이용하여 안전하게 본인확인할 수 있는 방안을 제안한다. 제안된 방식은 웹사이트 회원가입, 게시판 글쓰기 등 온라인 본인확인이 필요한 경우에 언제든지 이용될 수 있고 아이핀(i-PIN)에서 본인확인 수단으로 도입된다면 개인정보를 보호할 수 있어 활용 가치가 높을 것이다.

실크로드를 통한 문화 교류가 상고시대 우리나라 관모와 장신구에 미친 영향

이윤정(Lee Yun-Jung),정찬주(Chung Chan-Joo) 한복문화학회 2004 韓服文化 Vol.7 No.1

This empirical research aims to analyze any impact of cultural exchange through silk roads on Kwanmo and accessaries in ancient Korea. According to historical evidence. ancient Kwanmo in Korea originated from Schitai<br/> culture. which arrived at Shilla via several areas in silk road. Some Kwanmos with shapes of birds also dates back to northern asian tradition. In case of accessaries such as belts. earrings. pendents. rings. or handcuffs. they have something in common between Korean ones and Asian ones. The cultural exchange through silk road. made by political. religious or commercial transactions. contributed to bringing western art and way of life into ancient Korea. resulting in change or new development of its own culture.<br/>

고대 우리나라 의복에 미친 서역 의복의 영향

This paper aims to analyze the effect of cultural exchange the neighbouring countries to the west of China and ancient Korea on clothing. For this, we examined the clothing in arabic people, Korean diplomatic delegates on silk road, wall pictures in Samkook Age and Unified Shilla dynasty.<br/> Common pants in North East Asia came from Skitai Cultural region, which in turn originated from Ancient Westland. That is, Skitai moved the clothing culture from East Asia to Kokuryu. And Sculpture in unified Shilla showed smooth line, frame in arms and feet, and muscle, that seemed to be imported from Westland. In addition, woman clothing in that age showed evidence of contact between Westland or Tang with Shilla.<br/> This research shows that silk roads influenced religious, political exchange, commercial activities, and clothing of the people in that ages. That is, ancient Korean clothing has been largely affected by the West land, and also, of course, by natural environment and sense of beauty.

반도체 산업환경에서의 방진복 디자인의 개발

정찬주,정재은,이윤정 한국의류학회 2002 한국의류학회지 Vol.26 No.2

Based upon literature survey and questionnaire survey, this research tries to develop four new Cleanroom Garment in semiconductor industrial environment. The designs emphasize to minimize workers discomfort so that they can not only cover human body fully but also reduce dust as much as possible during work hour in dean room. The new designs characteristics and results from both function test and dust emission test are as follows: 1. In order to reduce dust-emission, we develop new designs with hood, kimono sleeve, and back zipper. The designs with hood face positive test results in term of motion suitability and dust-emission. The design with seam in front, in particular, is effective to control dust-emission. 2. For the purpose of reducing dust-emission, we also emphasize to minimize ease of dust-proof wear, with reference to previous research and clothing experiment. The experiment participants report that the new wears are not so comfortable as existing ones, but they accept the new wears positive as effective in reducing dust-emission owing to reduced ease of Cleanroom Garment and sleeves. 3. Also to reduce dust-emission in inner wear, we put inner wear in both Cleanroom Garments and inner wear, resulting to remove discomfort of wearers when changing clothes and of tight waist due to inner-trousers. 4. We develop new designs with elastic bands in both waist through the side lines and with velcro only at the back side. To remove twist in front contributes to reduce emission arising out of friction, also to free the appearance minding woman workers from worrying about exposed stomach. The new designs need to be accepted as a valuable alternative of Cleanroom Garment, in that they are highly effective to reduce dust-emission, which is the most important factor in the wear, in spite of some drawbacks in terms of motion-suitability, ease and appearance as shown in wearing test.

고청정 작업환경에서 방진복 디자인이 인체 생리반응에 미치는 영향

정찬주,정재은,이윤정 한국의류학회 2002 한국의류학회지 Vol.26 No.6

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. <Garment Designs> A. Coverall with non-detachable hood, kimono sleeves (font), 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), 100% cotton inner wear (upper body) The results of the experiment were as follows. Because the hood covered the shoulder and the chest areas, the chest 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 nondetachable hood was effective in minimizing dust, suppressing skin temperature increases, maintaining a superior microclimate and providing pleasant subjective sensations.

면과 폴리에스테르의 혼방비율에 따른 착용감에 관한 연구

이순원,정찬주 한국의류학회 1988 한국의류학회지 Vol.12 No.3

The purpose of this study is to investigate the effect of cotton, polyester and cotton/polyester blend fabrics on sujective wear sensations and physiological responses at the environmental conditions. Experimental garments were round neckline T-shirts made of 100% cotton, 50/50% cotton/polyester, 35/65% cotton/polyester and 100% polyester, respectively. Four healthy young women wern chosen as subjects for the experiment and the subjects have taken intermittent exercise for 30-min, on bicycle ergometer. Conditions of experimental chamber were as follows -Environment I ; Temperature 30±1℃, Humidity 70±3% R.H. and Air Velocity 0. 25 m/sec -Envorpnment Ⅱ; Temperature 22±1℃, Humidity 54±3% R. H. and Air Velocity 0.25 m/sec The results are as follows; 1) At Environment I, skin temperatures of chest and back covered with experimental garments were not significantly differnt, but, at Environment II , 100% polyester garment showed the higher skin temperature. 2) In both conditions, garment made of 50/50% cotton/polyester were felt the best `tactile sensation' and `comfort' 3) The significance of subjctive wear sensations among clothings are larger in Envirorment I than in Environment Ⅱ.
