  • 본 논문에서는 의료용 in-body WBAN (Wireless Body Area Network) 시스템을 위한 GM (Group Manchester code) 변조 방식을 제안한다. 현재 IEEE에서는 WBAN 시스템을 802.15. TG (Task Group) 6로 지정하고 이에 관한 표준화를 진행하고 있다. 높은 전력 효율이 요구되는 WBAN 시스템을 위해 최근 표준화 그룹에서는 PPM(Pulse Position Modulation) 신호 간의 grouping을 통하여 전송률 이득을 얻을 수 있는 GPPM (Group Pulse Position Modulation) 변조 방식이 제안된 바 있으나, 기존 GPPM 방식은 복조 과정의 SNR 손실 및 gray coding의 부재로 인한 BER 성능 열화가 나타나는 단점이 존재한다. 따라서 본 논문에서는 PPM 보다 잡음 성능이 우수한 Manchester code를 기반으로, GM 방식의 BER 성능 최대화를 위한 복조 방식 및 turbo coded GM을 위한 LLR (Log Likelihood Ratio) 판정 방식을 제안하였으며, 다양한 성능 2 분석을 통해 제안된 방식의 우수성을 입증하였다.

  • A case study was conducted on the development of patient clothes designs at the Korea University Medical Center, in order to provide an example of patient clothes designs which meet the hospital identity and the demands of patients and nurses. In this study, we focused on general patient pajamas and one-piece gowns worn in the obstetrics and gynecology department. A scientific and systematic design approach consisting of the following four steps was conducted in the designing process: needs assessment, design direction establishment, design presentation, and final decision. For the first step, focused group interviews and a survey were conducted to identify the needs of the patients and nurses. According to the results of the first step, 3 fabric patterns with light, modern, rhythmic, modest and ordinary images were designed utilizing the university and hospital symbols and logotypes. Fixed forms with realistic and geometric characteristics and colors, including white, yellow, blue, grey, and pink were selected to deliver the preferred image. Each fabric pattern was made in male and female versions of the color sets. The following styles of patient clothes were made with the 3 fabric samples: general patient pajamas with a U-neckline, 9/10-length sleeves and ankle-length pants, a full-length sleeved gown with openings for breast-feeding, and a gown with a deep back-neckline and button fastening. Different sizing systems for males and females were recommended for the production.

  • This paper is written in order to investigate how Lee Je-Ma changed traditional Zhu Xi's philosophical view on Way(Tao; 道) Virtue(De: 德) Nature(Xing;性) and Imperative(Ming; 命), which was general concepts of his contemporary age, to practical philosophy and created new medical theories of Sasang(4 symbols) science from it. Lee emphasized the true thing which is able to be done in one's living not the concepts of Sasang. So he induced the concepts of Way and Virtue from the easy and simple way(易簡之道) in the Classic of Changes(I'Ching) for the purpose of practice by anyone. Because Nature and Imperative are derived from Way and Virtue in the context logically, human life is virtual in itself, so the substance of Nature and Imperative became equal with Way and Virtue. Herein the names and concepts of original 'Sasang' were substituted to Business(事), Mind(心), Body(身), Thing(物) which is able to be directly related with human being in his daily life. And he explained variously about the responses of Mind and Body of individuals onto Business and Thing. So it could be applied in medical aspects like emotional, symptomatical, characteristic features. Conclusively man is virtual being, so Nature and Imperative in the level of Human being are based on Way and Virtue in the level of Heaven. For that reason the new concepts of Sasang Business. Mind. Body Thing or Heaven. Human. Nature and Imperative were proposed.

  • According to Confucianism, the world before Confucius focused on respecting the heaven which meant that everything could be done by the heaven. After the period of Confucianism, Joo-Ja asserted that everything could be done by nature. During the Chosun Dynasty, philosophers such as Seo Kyung-duck, Lee Hwang, and Lee Yi talked about four characters and seven passions of human being. They started to focus more on the inside of human nature. During the later period of the Chosun Dynasty, a philosopher by the name of Dongmugong Lee Jema analyzed that one's nature and feelings can change his or her external matter and the function of internal organs by purity or impurity of one's mind. Based on these analysis, Dongmugong discovered 'sasangin' which puts more emphasis on one's state of mind compared to the outside the world. Also, Dongmugong tried to figure out the connections between Confucianism and medical science. If you use change fire and stone theory which is difference between hado and nock-seo to expain four seven theory one's mind could be define as four natural characters and seven feelings. From four seven theory four is ying and seven is yang. This is the method of cure and understand the structure of human body. And also, four natural characters and seven feelings can be divided into heaven and earth. You can see Four natural characters is far more similar to heaven and seven feelings are similar to earth. According to four-seven theory hado is permanent and you can find out 'sasangin' is permanent also. Since seven feelings are influenced by sam-jae, you can analogize there are 21 different types in 'sasangin'. An underlying principle should there be 28 different types of sasangin instead of 21 different types of sasangin but one quater of sasangin is hidden according to samhyuniljang theory. All creations in the world are organized by unification of the great absolute and symmetry distinction of yingyang. With these facts identity of the heaven, earth and man which is named samjae generates symbols of independent sasang. And also, sasang generates relations between five element, six energy and the six family relation. From six family relation comes seven feelings of man which creates a category of the eight trigrams for divination and unification of nine palace. All these process are united.

  • They say Y$\breve{o}$k'ak(易學) is the root of Oriental studies. This means philosophy, astronamy, geography, medicine, music, numbers are all based on Yin-Yang, and Five phases theory of Y$\breve{o}$k'ak. Nowadays studies are very much specialized but as we go back to old times, we cannot dearly set these studies apart. All the studies can be comprehensively understood with Y$\breve{o}$k'ak(易學). The original purpose of Y$\breve{o}$k'ak is to predict future with highly symbolized signs, Sang-Su(象數). However you cannot fully understand Y$\breve{o}$k'ak without knowing the principle of change in Sang-Su itself. We have to keep thinking about how we should further study Y$\breve{o}$k'ak, treat diseases with Sang-Su, and how Sang-Su can be used in medicine. As a previous step to this process, I will consider relationship of Y$\breve{o}$k'ak and medicine in this paper. This study will help us to set the goal and method in studying medicine. Conclusions of this paper are following: 1. The purpose of understanding a subject is to understand the principle of the subject. The principle of every subject can be turned into principle of changes in the universe. This principle is not affected by time nor space. It is only seen through the changes of subjects. 2. The reason we cannot easily understand the principle is that we have biased mind. How we should overcome this is through developing virtue, and by keep inspecting things over and over. 3. We see the outcome of changes inside but we should not neglect the principle. Therefore we see the principle through Sang. Sang is in between Principle(理) and Things(物), thereby has characteristics of both. Which means it is much like Principle but specific Things is related and it is much like Things but it is not easily understood. 4. There are various kinds of Sang. Mind-Sang(心象) is an image that comes before expressing it with symbols or words. When it is expressed in symbols or words, it is no longer considered as same Sang. Sang in symbol are Kwaesang(卦象), Hyosang(爻象) and Sang in words is Kyesa(卦辭). The characteristic of all these Sang is that it cannot be explained through the logics. 5. If we call Sanghak as the study with Sang, the method is same as that of understanding the principle. The fundamental purpose of Sanghak is to understand the principle of things and then apply this principle to the practical world so that the world can be a better place. So I would say Sanghak is the study of a saint and a ruler. 6. Since the object of medicine is human being who are the mixture of Principle and Ki, we can use Sang which is also related to both Principle and Ki. Actually terms we use in Oriental medicine are not easily understood without the knowledge of Sanghak. 7. When we diagnose a patient, we are looking for Sang that comes from the body inside. When we do the treatment, we cannot neglect the original change that's happening in our body. Therefore studying Sang is a necessary step to do the full diagnosis and treatment. 8. The method of studying medicine is first to get rid of biased mind, taking right Sang from various classics and then apply those Sang to actual situations.

  • C. G. Jung은 일찍이 신화(神話)나 민담(民譚, Märchen)에서 인간 무의식의 보편적, 원초적 조건이 발견된다고 하였다. 우리의 일상에서 이러한 인간심성의 보편성을 흔히 체험할 수 있는 것은 꿈이다. 그러므로 꿈에 나오는 인간 심성에 있는 보편적인 원형상들을 이해하기 위해서 신화소(神話素)들이 등장하는 신화나 민담들에 대한 분석심리학적 해석을 시도해 보는 것은 실제 임상에서 마주치게 되는 이런 '큰 꿈'들을 충실히 이해하기 위해 매우 중요한 과정이다. 저자는 신화에 대한 분석심리학적 해석에 관심을 가지면서 그 대상에 대한 탐색을 하면서 신화소에 나타나는 '원형'의 보편성을 우리 민족 전래의 신화 속에서 찾아보기 위해 삼국유사를 살펴보던 중 기이편(紀異篇)에 나오는 신라(新羅)의 건국신화인 혁거세왕(赫居世王) 신화에 주목을 하게 되었다. 신라는 일찍 건국이 되긴 하였지만 한반도 남부 끝자락에 위치한 제일 작은 나라로서 고구려, 백제에 비해 정치, 군사적으로나 문화적으로 가장 늦게 발전한 나라였음에도 결국 삼국을 통일하고 우리나라 역사상 가장 긴 거의 1000년(BC57~AD935)의 역사를 이어온 나라라는 점에서 건국과 관련된 남다른 바탕이 있었는지 그들의 건국신화에 있는 원형상(原型像)들을 살펴보고자 하였다. 한반도의 남쪽 작은 나라였던 신라의 건국시조의 탄생신화가 탄생전의 상태에서부터 탄생, 배필의 탄생, 성장, 결혼, 즉위, 다스림, 죽음, 죽음 이후, 계승까지 거의 완전한 줄거리를 갖고 있다는 것은 매우 주목되는 점이다. 이 신화에 나오는 1, 3, 5, 6, 7, 13, 61 등 다양한 숫자 상징, 동, 서, 남, 북과 중심을 포함한 모든 방위, 호랑이, 백마, 닭, 용, 봉(鳳) 뱀 등 많은 동물상징, 중심적인 상징인 알을 비롯한 바위, 박(瓢), 전광(電光), 샘물, 내(川), 나무, 숲, 산, 쇠 등 자연의 상징과 선도성모 같은 신상(神像) 등 점차 이야기가 전개되면서 등장하는 온갖 상징들은 이 짧은 신화 속에 온 인류가 경험해온 의식의 탄생, 부성과 모성의 합일을 통한 성장과 발전, 소멸, 재생의 이야기가 펼쳐지고 그런 과정이 다음 세대로 영원히 계승되는 웅대한 이야기가 재현되고 있음을 볼 수 있다. 신화의 한 단어, 한 문장 또는 별로 의미를 찾을 수 없어 보이던 내용들이 점차 그 뜻을 드러내고 있었고, 무의식과 의식의 상호 작용이 그 모습을 달리 하며 계속 반복되며, 중층적으로 표현되고 있음을 확인할 수 있었다.

  • 고차 QAM 시스템에 대한 자기적응 등화에서 눈 모형이 완전히 닫힌 등화 초기에 적용하여 눈 모형을 빠르게 열뿐만 아니라 정상상태 오차 레벨을 크게 낮추는 새로운 SDD 알고리즘을 제안한다. 제안 방법은 M-QAM 응용에서, 관찰에 가장 인접한 두 심볼을 추정의 기반으로 함으로써 기존 SDD의 계산 복잡성을 최소화하고, QAM 차수에 무관하게 연판정을 크게 단순화하였다. 아울러 심볼 추정에 임계 함수에 비해 오판정 회피가 우수한 시그모이드 함수를 적용, 추정의 신뢰도를 높였다. 또한 등화기 갱신을 위한 오차 발생 시 임계 함수에 의한 심볼 판정 값을 오차에 가중하여 오차 변동 범위를 확장함으로써 제안한 자기적응 등화기의 초기화 성능을 개선하였다. 결과적으로 제안 방법은 기존 SDD의 계산 복잡성과 초기화 및 수렴 특성을 현저히 개선하였다. 부가 잡음이 존재하는 다중경로 채널 조건에서 64-QAM 및 256-QAM에 대한 모의실험을 통해 CMA와 제안한 2-SDD 및 가중된 2-SDD의 두 가지 형태의 성능을 비교하고 제안 방법의 유용성을 확인하였다.

  • This study is intended to understand an implication system and significance in the current community which a body image symbolizes by correlating it with fashion that is on the rise as a principal issue in various fields. For this study, the symbolism of the body image was contemplated in terms of philosophy and art, and then on the basis of it, the symbolism of the body image shown in modern fashion design was analyzed through fashion works. The research results are as follows, 1. The manifestation of sex can be taken as the symbolism of the body image which is expressed in modern fashion design. Recently sexual chaos and vagueness such as homosexuality and bisexuality are expressed through a dress and its ornaments. Though displaying sexual characteristics of male and female as they are exposing a sign or a diagram, decorating a part of body or representing sex in garments, uncertain sex identity in modern society is manifested in dress and its ornaments. It is to deny absoluteness regarding sex and emphasize diversity indwelt in human beings, and after all it shows to pursue the human essence. 2. Another symbolism of the body image is body expression as the human race and an ethnic group. The discriminating situations and the restoration of their status appeared in modern fashion too. Moreover, their cultures and issues came to alter the aesthetic standard of body made from a view of the Western white supremacist. Hereupon, fashion trends like ethnic fashion, Orientalism and African look etc. appear according to this tendency, which represents race and national identity and in addition, which signifies to present transcendental human conception embracing alienated human conception. 3. The symbolism of the body image expressed in a body, and a dress and its ornaments as nature can be considered in terms of the concern on environmental contamination and the respect of echo system. Getting away from reigning over, developing and stamping down nature at their will, the human beings pursue unity with nature, which is described in fashion. They are stressing that natural materials and objects such as animal, plant and soil etc. should activily be introduced into fashion and humans are a communal fate group and should reframe their status in nature at last. 4. The body image shown in a body, a dress and its ornaments as technology is transformed and recreated by modern scientific techniques and medical science to show post human conception namely, forthcoming future human conception as a cyborg which loses individual identity. This presents a perfect future human conception with high level of preternatural power but after all, leaves us a task to seek the meaning of human existence in alienation caused by the loss of human identity and existence. In this manner, the moderns crave for perceiving the identity of a natural human being in the current thoughts tendency of the modern times such as postmodernism, post structuralism, deconstructionism, feminism and so on, which build discussions affecting the art and fashion worlds. The categories, like sexual characteristics indwelt in a human body, racial classifications, the natural environment surrounding human beings and development of science, bring out the importance of the internal and external meaning in today's fashion which a human body contains, and present sew human conception in the coming future society.
