Joohun Lee,Haehyun Jung,Jaejoong Lee 보안공학연구지원센터 2015 International Journal of u- and e- Service, Scienc Vol.8 No.9

Development in digital technology and video technology significantly contributes to increases of the utilization of video sources in a variety of performances. At the same time, the necessity to promptly control and change the video gets higher, especially in live performance. In these circumstances, if the performer could control the video depending on actions without need of direct contact to the device, live video performance will be much faster and more convenient. In other cases, DJ who carries out mixing music in club and DJ party would like to take a role of visual performer as well, or control background video in realtime corresponding to the music being played. In these cases, gesture recognition based non-contact interface could be advantageous over a traditional way of touching or contacting the device directly. To this end, the starting point of our study is to devise the user interface that enables a live video production making use of hand gesture recognition device. However, the hand gesture recognition based user interface might cause unintended wrong recognition due to similarity of device-controlling hand gesture and normal hand gesture. To prevent this, we introduce the gesture-recognition mode switcher using pre-gesture.

A Study on the Artistic Representation of the Cellular-Phone Addiction and the Personal Data Leakage of Modern Society

Joohun Lee,Jiseon Baek 한국인터넷방송통신학회 2015 International Journal of Internet, Broadcasting an Vol.7 No.2

Although the development of digital technology and network has brought great convenience in modern lives, amongst the aggravated complexity in the contemporary society, modern minds who have failed to create genuine relationships undergo a sense of alienation and solitude that may appear as a type of social pathology called cellular-phone addiction. Also, while the emergence of the information age seemingly brings about benefits including diverse acquisition regarding knowledge and broader communication, underneath exists side effects involving leakage of private information. Especially, being excessively addicted to relationship network may induce one to become insensitive towards leakage of private information without recognizing, and thereby instigating yet another social problem. Media art is very practical in terms of suggesting a critical perspective concerning social phenomena and elevating them into a work of art by rendering them artistically. Particularly, when social problems of the modern days are expressed through digital technology, media art provides the audience with a foundation that will enable them to sympathize without hostility. This dissertation calls attention to the contemporary problems regarding cellular-phone addiction and possible hazards of information leakage based on media art, while at the same time proposing the production process of a media art work that attempts to raise awareness and sympathy on such social issues.

어린이 놀이로서의 인터랙티브 미디어 설치

이주헌 ( Joohun Lee ),양소정 ( Sojung Yang ) 한국영상미디어협회 2013 예술과 미디어 Vol.12 No.1

인터랙티브 미디어 설치작품들은 관객의 호기심 과 상상력, 오감을 자극하여 정서적 물리적 상호작용과 자발적 참여를 이끌어내고 새로운 미적 경험을 제공할 뿐 아니라, 어린이용 놀이로서 놀이 본연 의 가치를 드러내는 장점이 있다. 이는 어린이의 감 성발달과 창의성 향상에도 매우 중요한데, 본 연구 에서 제안된 인터랙티브 미디어 설치작품들은 어린 이 놀이로서 이러한 장점들이 잘 드러난다. 또한, 호기심을 자연스럽게 유발하고 장시간 작품에 몰입 하여 놀이처럼 즐기게 함으로써, 기존의 디지털 놀이기기들이 가진 부작용의 염려를 크게 줄일 수 있음을 보여준다. 제시된 작품들은 관객의 적극적인 반응을 이끌어내는 인터랙티브 미디어 설치작품으로, 관객들은 자신의 몸에 반응하는 가상의 이미지 들과 상호작용하며 놀이를 하듯 작품을 감상한다. 이 때, 다양한 무지개색의 물방울, 형형색색의 불꽃, 실로폰 소리 등을 통해 오감을 자극함과 동시에 관 객의 몸에만 반응하게 하여 관객의 적극적 신체활 동을 유발한다. 이는 기존의 디지털기기의 놀이와 달리 놀이 본연의 가치가 잘 드러나며 다수가 동시 에 즐길 수 있어서 타인과의 교감에도 유익하다. Interactive media installation works prompt imagination and stimulate five senses to give new aesthetic experience via emotional and physical interaction and voluntary participation. With these features, interactive media installation works prove their own effectiveness as a plaything for children as well as induce children to interact physically with those works. Additionally, they make children have curiosity spontaneously and enjoy it like a play with being immersed in works for a long time. This means that the interactive media installation works can be fairly valuable whereas the existing digital playthings often give bad influence to children. In this study, several interactive media installation works are introduced, which act as a good plaything by bring interactive and communal manner. Those works induce the audience, especially children, to play with virtually falling rain drops which interact not with other objects but only with the body of the audience. And they give xylophone sounds or change into fireworks with bouncing only when they are touched by the body of audience. Thorough these works, interactive media installation shows a possibility of an excellent digital play for children without the bad antisocial influence which the existing digital games may have.

암 발생과 진화 과정에서 돌연변이 역할 비교

하주헌(Joohun Ha) 한국창조과학회 2022 Origin Research Journal Vol.2 No.2

생물학에서 돌연변이는 DNA의 염기서열의 변화를 의미한다. 현대 분자생물학을 통해 잘 확립된 유전 정보의 발현 순서는 DNA로부터 RNA가 만들어지고 RNA로부터 단백질이 만들어진다는 것이다. 유전 정보를 갖는 DNA로부터 실질적 기능을 수행하는 단백질이 만들어지는 일련의 과정을 센트럴 도그마라고 부른다. 따라서 DNA에 일어나는 돌연변이는 생명체에 막대한 영향을 유발할 수 있다. 이러한 돌연변이는 세포가 복제되는 과정에서 자연스럽게 발생할 뿐 아니라 다양한 세포 내외부의 자극에 의해 발생하기도 한다. 사람의 경우, 이러한 돌연변이가 발생할 때, 원래의 염기 서열로 복원시키는 다양한 DNA 복구 시스템이 존재한다. 본 논문에서는 암 발생 과정과 진화 과정에서 추정되는 돌연변이의 역할을 비교해 보고자 한다. In biology, mutation indicates alterations in the sequence of nucleic acid of an organism. The most-well established flow of expression of genetic information is that RNA is made from DNA and the protein is made from RNA. This process is called central dogma. Therefore, mutations in DNA can significantly affects various aspects of the organisms. DNA mutations occur naturally during the cell division, and it can be caused by extra or intracellular stresses. Humans have a variety of DNA repair system, which identifies mutations or DNA damages and repair them. In the present study, I will compare and analyze the putative role of mutation during tumorigenesis and evolution process.

관객의 자아인식 성찰을 위한 인터랙티브 디지털 미러의 구현과 의미

이주헌,김형기 영상예술학회 2010 영상예술연구 Vol.16 No.-

자아를 탐구하고자 하는 인간의 욕망은 오랫동안 수많은 철학자들의 주된 주제였으며, 많은 작가들에 의해 자화상이라는 작품으로 표현되었다. 또한, 자신을 인식하는 도구로서 오랫동안 거울이 사용되어 왔다. 급변하는 현대 사회 속에서 사람들은 자아의 의미와 정체성을 상실하고 소외를 경험하게 된다. 특히 개인화된 미디어의 확산 속에서 개인은 더욱 고립되고 소외되어 자아인식 및 정체성의 혼란을 가져온다. 이러한 환경 속에서 ‘디지털 미러’를 통한 ‘인터랙티브 자화상’이라는 형식의 작품을 통해서 자아의 정체성 규명의 필요성을 느낀다. 본 연구에서는 관객의 모습을 비디오로 촬영하여 실시간으로 보여주면서 관객의 모습을 디지털적으로 변화시킴으로써, 관객의 참여를 통해 표현된 영상 이미지를 통해서 관객 자신에 대한 자아인식의 문제에 천착하게 하는 몰입의 경험을 제공하는 작품을 구상하고 설치를 통해 구현하였다. 차영상을 이용하는 영상신호처리 기술을 응용하여 구성된 디지털 미러를 통해서 관객은 자아를 관찰하게 되는데, 이때에 보여지는 자신의 모습은 실제 모습이 아닌 자신의 실루엣만 남은 투명인간의 형태를 가진다. 이는 진정한 자아는 존재하지 않는다는 라캉의 거울이론과도 일맥상통하는 부분이다. 즉, 그동안 비디오와 스크린, 혹은 모니터를 통해 자신의 모습을 촬영하고 감상하면서 그것이 실제의 자신이라고 믿었던 현대인으로 하여금 그와 같은 ‘디지털 미러’를 통해 본 자신의 모습이 자신의 실제가 아님을 인식하게 하려는 것과 같은 것이다. 이와 같은 작업을 통해, 관객은 물리적 거울을 보았을 때 나타나는 실제와 같은 자신의 모습에 대한 정체성에 대한 질문을 받고 자신의 본질에 대한 의문을 품게된다. 또한, 화면 전체에 디지털적인 변화를 준 기존의 디지털 미러 작품들과 달리, 관객이 서있는 배경은 거울과 같이 있는 그대로 비춰주고 관객의 모습만 디지털적인 처리로 투명하게 지움으로써 관객은 보다 자신의 문제에 집중할 수 있게 된다. 또한, 관객이 작품의 중심이 되어 표현되고 관객의 모습에 작품이 변함에 따라, 관객은 작품에 적극적으로 반응하며 인터랙티비티를 경험함으로써, 인터랙티브 디지털 미러에 몰입하게 된다. For a long time, many philosophers have studied a human’s desire to investigate himself as one of main theme and many painters have left their own self-portraits to express their inner sides. Also, for human, mirror has been used as one of tools to recognise theirselves. In modern society, peoples live with being lost the meaning of their exist and even their identities so to exprience a sense of alienation. Especially, in overflow of personal media, each person become more isolated and alienated so to, finally, feel confused about his selfperception and identity. Under this kind of environment, the investigation of self identity of human becomes needed using ‘digital mirror’ as one of ‘interactive self-portrait’. In this study, video camera takes the images of a viewer and projector shows the digitally-processed images of them in real time. For viewer to watch his processed self-images make him to investigate his identity. By using the difference of two images, the prerecorded background image and the current image, the viewer finds only him an invisible man with background shown normally. This represents one case of the subject theory of Jacques Lacan. In his theory, real ego does not exist. Generally, people believe that the self-images shown through screens or monitors are real themselves. However, by the works of interactive digital mirror based on the theory of Lacan, they become realized that their self-images in mirror are not real themselves. By this kind of works, viewer faces a question that the self-image shown even in the normal mirror equals a real ego when he stand in front of mirror. Finally, he experience a feeling of being immersed in a question of his identity. The works of interactive digital mirror are differentiated from other previous digital mirror because they focus only on the transformation of viewer’s image not on the background image. This make it possible for the viewer to concentrate only his existence and identity problem. Also, the viewer becomes main theme of the works. Consequently, he participates in and reacts to works on his own initiative. This reveals the true sense of ‘interactive digital mirror’.
