신효영,정계동,Shin, Hyo-Young,Jung, Gye-Dong 한국정보통신학회 2010 한국정보통신학회논문지 Vol.14 No.5

최근 RFID 시스템은 유통, 의료, 군사 등 다양한 영역에서 활용하는 기술로 등장하고 있다. RFID 시스템을 여러가지 응용 서비스에 적용하려면 개인정보를 보호하기 위한 기술이 개발되어야한다. 본 논문에서는 해시 함수를 이용하여 RFID 태그와 데이터베이스간의 상호 인증을 효율적으로 수행할 수 있는 프로토콜을 제안하였다. 제안한 프로토콜은 상호 인증, 익명성, 비밀성, 무결성, 재전송 공격, 위치 추적 등 여러 가지 보안 요구 사항을 만족시키면서, 데이터베이스에서의 해시 연산 횟수를 줄여 전체 인증 시간을 줄일 수 있다. Recently RFID system is used in various fields such as distribution industry, medical industry and military service. The technology for protecting individual privacy is necessary to adapt RFID system in several applications. This paper proposes an authentication protocol which conducts mutual authentication between back-end database and tag using hash function. The proposed protocol satisfies various RFID security requirements : mutual authentication, anonymity, confidentiality, integrity, replay attack, location trace. This protocol reduces the time for authentication minimizing the number of hash operation in back-end database.

유지(油紙) 관련 고문헌 고찰 - 조선시대 문헌을 중심으로 -

신효영,최태호,정선화,Shin, Hyo-young,Choi, Tae-ho,Jeong, Seon-hwa 국립문화재연구원 2013 헤리티지:역사와 과학 Vol.46 No.3

유지(油紙)는 선조들이 사용했던 생활필수품으로 종이에 기름을 먹인 전통적인 가공지이다. 그러나 현재 유지(油紙)에 대한 정확한 연구가 부족한 실정이므로 유지의 문헌사적 연구를 통해 유지의 기원과 명칭, 용도, 제작기법에 대하여 조사하였다. 고문헌으로 확인된 유지의 기원은 "고려도경(高麗圖經)", "고려사(高麗史)"의 내용을 통해 고려시대로 추정하였으나, "삼국사기(三國史記)"와 "일본서기(日本書紀)"에 나타난 기름과 종이의 기록으로 보아 7세기경부터 유지제작이 이루어졌을 가능성도 배제할 수는 없다. 조선시대는 "조선왕조실록(朝鮮王朝實錄)", "일성록(日省錄)", "승정원일기(承政院日記)" 기록을 통해 유지의 명칭과 사용법에 대해 조사하였으며, 의궤류와 "탁지준절(度支準折)" 등 기타 여러 분야의 고문헌 내용을 바탕으로 절가와 용도, 제작재료에 대하여 조사하였다. 조선시대의 문헌 조사결과 유지는 방수, 방습, 투명성 등의 특성으로 인해 각종 생활 용품으로 사용되었으며, 그 용도와 제작과정에 따라 다양한 명칭으로 불리기도 하였다. 본 연구를 통하여 조선시대 유지 관련 문헌조사가 이루어졌으나 전통 유지 복원에 관한 연구는 아직도 부족한 상태이다. 그러므로 현재 남아 있는 유지 유물조사연구와 전통 유지 샘플 제작 실험, 또한 유지를 제작하고 있는 장인들에 대한 사례 조사가 병행되어 전통 유지 연구가 이루어져야 할 것으로 생각된다. Oiled paper (Yuji, 油紙) is an oil impregnated paper which was one of the daily necessities in Korea. As there has not been any accurate research on this subject, this study examined the literature from the Joseon Dynasty to study its origin, nomenclature, usage and production process. Goryeodogyeong (高麗圖經) and Goryeosa (高麗史) allowed the estimation that the origin of oiled paper was the Goryeo Dynasty, but the records of oil and paper in Samguksagi (三國史記) and Nihon Shoki (日本書紀) indicate the possibility that the production of oiled paper can be traced back to the 7th Century. The nomenclature and the usage of oiled paper in the Joseon Dynasty were examined through the Annals of Joseon Dynast (朝鮮王朝實錄), Ilseongnok (日省錄) and Seungjeongwonilgi (承政院日記), while the Royal Protocols of the Joseon Dynasty (Uigwe, 儀軌) and Takjijunjeol (度支準折) together with other literature were examined for its market value, use and materials. The literature from the Joseon Dynasty indicate that oiled paper was used for various everyday commodities with its waterproof, damp-proof and transparent properties and called in various ways according to its use and production process. This study studied the literature on oiled paper from the Joseon Dynasty, but the studies on the restoration of traditional oiled paper are still needed. Therefore, it would be necessary to study the traditional oiled papers in combination with the study of oiled paper relics, the reproduction of traditional oiled paper samples, and the case study of the papermaking masters who have been producing the traditional oiled papers.

가다머(H. G. Gadamer)의 ‘놀이’ 개념을 통해 본 마당춤의 이해와 해석

신효영 ( Hyo Young Shin ) 대한무용학회 2020 대한무용학회논문집 Vol.78 No.3

The logic of Gadamer with concept of 'play' convert the audience who participated in performance passively to the who is leading the performance actively, by dance performance itself is experienced uniquely by dancers choreographers as well as audience and opening the possibilities of change the meaning of work through the communication with audience. After the adapting the play concept of Gadamer to the MADANG(open air) dance, the participating characteristics of yard dance and motility have many similities with the structure of 'play' and we found that the MADANG(open air)dance is the appropriate destination visualizing the transformation as formation by direct participation not just contemplation and excitement or fun with play.

메를로-퐁티 ‘몸’ 철학에서 본 미니멀 댄스

신효영 ( Hyo Young Shin ) 대한무용학회 2021 대한무용학회논문집 Vol.79 No.3

Minimal dance Influenced by Merleau-ponty's philosophy of ‘Body’, they want to cheer for the dance as the main issue of body movement. Merleau-ponty's phenomenological philosophy of thinking of the human body as an expression of existence has many things in common, including the essential source of body movement and perception, the orientation of the body in space, the attention to specific experience, the relationship between the subject and object, and has brought about by the Judson Group's avant-garde work in dance, development or through a variety of dance approaches.

한국 춤의 정서적 순환구조에 관한 연구 : ‘한(恨)’과 ‘신명(神明)’을 중심으로

신효영 ( Hyo Young Shin ) 대한무용학회 2021 대한무용학회논문집 Vol.79 No.2

Koreans' ‘Han’ saw that it was possible to create aesthetic and ethical values by creating ‘Shinmyeong’ through the process of cutting and washing the inside, not bringing revenge. The Korean people's Han and Shinmyeong are formed in a circular structure, and the Han to Shinmyeong's circular structure is a phenomenon that can be seen throughout Korean art. Korean dance is a dance of spirituality that breaks through deep resentment. The representative folk dances such as ‘Mask dance’ and ‘Salpuri’, a traditional dance, are all based on the sorrow of the Korean people, but are all moving toward a structure of divinity that transcends their sorrow.

Oiled Korean traditional paper was mainly used in portraits, books, and household goods. However, there is a lack of research on manufacturing methods and techniques for oiled paper products. This study was carried out to investigate the properties of plant seed oils for oiled Korean traditional paper. Sesame seeds (Sesamum indicum L.), perilla seeds (Perilla frutescens var. japonica Hara), and tung nut (Aleurites fordii Hemsley ) were used for oil expression. Yield, viscosity, acid value, peroxide value, and fatty acid composition of sample oils were analyzed, respectively. The oil yields were over 30% and the perilla was the highest. The viscosity of oil was 41.3 cP for perilla seeds, 64.0 cP for sesame seeds, and 248.8 cP for tung nut at 20℃. As the heating temperature increased, the viscosity of oils decreased and the viscosity of tung oil decreased rapidly. Appropriate temperature of oil suitable for oiled Korean traditional paper was determined to be 60℃ in the sesame oil and the perilla oils and 70℃ in the tung oil. Acid value was highest in the sesame oil, but peroxide value was highest in the tung oil. The optimum temperature of oil for oiled Korean traditional paper did not affect the acid value and the peroxide value change. Linoleic acid and linolenic acid were the main components of the sesame oil and the perilla oils and the palmitoleic acid and stearic acid were the main components of the tung oil.

Balanchine succeeded principles, rules of Classic Ballet and he also showed specialties of Neo-Classicism Ballet such as 1) insisting Plotless style which rejects story or gesture 2) emphasizing on motor sensation of dancer’s body 3) emphasizing on relationship between music and dance.

한국 미니멀리즘 춤의 미적 특성-한국 창작춤을 중심으로

신효영 ( Hyo-young Shin ) 대한무용학회 2019 대한무용학회논문집 Vol.77 No.1

Korean Minimalism dance was the manifestation of eastern thought which was very familiar to Koreans. Aesthetics of “Move in the Stillness” - subtle movement in stillness, aesthetics of extreme equilibrium and temperance, and the state of completeness connected to stream of consciousness - was the basis of Korean minimalism. In addition, Korean Minimalism developed in relation to the Chinese ideas-ideas that things would go as they were destined to without external interference - and “Ideas of Energy” - that is, things would move harmoniously by their own energy, which flourished in the Oriental paintings. Minimalism in Korean dance had a different backgrounds from the Occident which could be thought more spiritual and could be found in the traditional ideas of the Orient.
