2000년대 초 인간 지놈 프로젝트의 완성으로 새로운 포스트-지놈 시대를 맞이하여, 유전자에 대한 해독보다는 인간의 모든 대사와 질병에 직접관여 하고 있는 단백질의 구조와 기능에 대해 많은 관심과 연구가 이루어지고 있다. 특히, 특정 단백질들은 암과 같은 불치병에 직접관여 하고 있으므로 이러한 단백질들의 기능과 구조에 대한 예측 성능의 향상은 새로운 신약 개발에 큰 도움이 될 것이다. 본 논문은 기계학습(Machine Learning)의 한 분야인 HMM(Hidden Markov Model)을 이용하여 $\beta$-barrel 형태로 막횡단하는 단백질의 특성과 기능으로부터 막횡단하는 부위가 존재하는지 여부를 예측하는 프로그램을 구현했다.

Post-tensioned concrete pavement(PTCP) was developed to built long-span concrete pavement(120 m span) and to maintain long-term service life(over 40 years) of concrete pavement. In the present study, research for high-durable concrete was conducted to utilize the advantage of PTCP construction method efficiently. First of all, 20% of fly ash(by binder weight) was replaced to control alkali silica reaction. Second, silica fume was applied to improve the water-permeability and early-age strength. Results of tests for mechanical properties, water-permeability resistance, and surface-scaling resistance of ternary blended cement concrete showed that the early-age strength was improved significantly with addition of silica fume. The water-permeability resistance was improved from "Low" to "Very Low"(ASTM C 1202). However, surface-scaling resistance was decreased with an increase of silica fume, therefore, content of silica fume should be kept in less than 5%(by binder weight) to assure field application considering durability. The results of air-void analysis showed that durability factors were improved since spacing factors were estimated as 250$\pm$15 micron in adjusted mixtures.

This paper aims at providing a critical view over the cybernetics theory especially of first generation on which the artificial intelligence heavily depends nowadays. There has been a commonly accepted thought that the conception of artificial intelligence could not has been possible without being influenced by N. Wiener's cybernetic feedback based information system. Despite the founder of contemporary cybernetics' ethical concerns in order to avoid an increasing entropy phenomena(social violence, economic misery, wars) produced through a negative dynamics of the western modernity regarded as the most advanced form of humanism. In this civilizationally changing atmosphere, the newly born cybernetic technology was thus firmly believed as an antidote to these vices deeply rooted in humanism itself. But cybernetics has been turned out to be a self-organizing, self-controlling mechanical system that entails the possibility of telegraphing human brain (which are transformed into patterns) through the uploading of human brain neurons digitalized by the artificial intelligence embedded into computing technology. On this background emerges posthuman (or posthumanism) movement of which concepts have been theorized mainly by its ardent apostles like N. K. Hayles, Neil Bedington, Laurent Alexandre, Donna J. Haraway. The converging of NBIC Technologies leading to the opening of a much more digitalizing society has served as a catalyst to promote the posthuman representations and different narratives especially in the contemporary visual arts as well as in the study of humanities including philosophy and fictional literature. Once Bruno Latour wrote "Modernity is often defined in terms of humanism, either as a way of saluting the birth of 'man' or as a way of announcing his death. But this habit is itself modern, because it remains asymmetrical. It overlooks the simultaneous birth of 'nonhumaniy' - things, or objects, or beasts, - and the equally strange beginning of a crossed-out God, relegated to the sidelines."4) These highly suggestive ideas enable us to better understand what kind of human beings would emerge following the dazzlingly accelerating advancement of artificial intelligence technology. We wonder whether or not this newly born humankind would become essentially Homo Artificialis as a neuronal man stripping off his biological apparatus. However due to this unprecedented situation humans should deal with enormous challenges involving ethical, metaphysical, existential implications on their life.

전 세계는 covid 19의 pandemic 상황이 장기화되면서 화장품 분야의 trend 변화가 일어나고 있다. covid 19의 예방으로 마스크는 생활필수품이 되었고, 행정적으로도 사무공간에서도 마스크를 착용하지 않으면 과태료를 부과하는 상황에 이르렀다. 이로 인하여 장시간 마스크 착용은 필수 불가결한 상황이며, 이로 인하여 얼굴 피부의 장벽기능(barrier function)의 와해로 인하여 피부가 예민해지고 크고 작은 피부의 trouble이 많이 발생하고 있다. 이에 따라 소비자들은 화장품의 선택에 있어 피부 진정과 피부에 자극완화(anti-irritation) 및 안전성(safety)에 대한 것으로 점차적으로 변화하고 있다. Covid 19 이전의 화장품 소재 및 제품 개발의 트렌드는 국내의 기능성화장품 범주에 있는 미백 관련, 주름관련, 자외선 차단관련, 염모관련, 육모 탈모 관련, 여드름관련, 피부장벽관련, 튼살 관련 기능성 소재 및 제품 개발과 화장품 용도외의 고기능성 부여를 위한 코스메슈티컬(cosmeceutical)용 제품의 개발이 중요한 시기였다. 코스메슈티컬(cosmeceutical)은 화장품(cosmetic)과 의약품(pharmaceutical)의 합성어이다. 그러나 최근 Covid 19의 상황에 따라 화장품 업계는 포스트 코로나의 트렌드로 피부 장벽기능 강화, 피부노화 억제, 식물성, 자극완화, 비건, 안전성 확보에 대한 다양한 천연 소재의 연구와 제품을 개발 출시하고 있다. 따라서, 2020년 Covid 19의 상황에 따른 화장품 분야의 천연 신소재 및 화장품 개발 방향에 대하여 자원 식물의 활용성 및 개발 동향에 대하여 논의 하고자한다.

All artists set the arrangement of relative probability subjectively by giving the contrast of color and chroma to give higher probability of some colors in their works and then perform the mechanical assignment. Also the analysis of plastic structure in all areas of design has been made by subjective and qualitative method based on the emotion, intuition and experience of interpreter of design structures and that of color structures was done by the same method. Therefore this study compares and suggests the style characteristics of modern and postmodern design with the object quantitative analysis of color structure by selecting and applying Ilya Chashinik's ceramic dishes as the analysis product of modern design and Jim Melchert's ceramic wall painting as that of postmodern design of 'analysis model of color structure' researched and developed for the quantitative information analysis based on information and communication theory and it is also meaningful in introducing and presenting the analytic procedure and methods centering around quantitative analysis model of color structure analysis.

Planning a major change in the domestic residential complex 'complex' in the 'city' to the influx of urban space. So, considering a set of self-environmental complex of openness and connectivity between cities inflow from residential urban housing is formed. Complex-oriented development approach and apartment high-rise and high-density regions of space and social disconnection that causes a uniform methodology that can solve the problem of housing plan, however, a recent New Urbanism New Urbanism has been introduced. And intravenous forms of communal life that occurred in the United States prior to World War II, this value is based on the main form. Design reorganizes This modern lifestyle factors (such as housing, jobs, shopping, leisure space) to go back to the traditional lifestyles while Neotradiotional Planning exercise. New Urbanism in the late 20th century, some literature refers to a postmodern approach adopted in the field of urban planning, the specific case. Actually important feature of post-modernism in the New Urbanism has been expressed. Problem is very confusing, and the principles of New Urbanism, New Urbanism, even those who claim that have different social and design views. Therefore, this study explores the postmodern tendencies of the New Urbanism, and based on this, the possibilities for the development of new towns in Korea mainly affected on the theory of New Urbanism in South Korea in Eunpyeong examine.

To study how digital content can be effectively developed and transformed in a post-COVID world in which the normal operations of museums have been disrupted, this paper analyzes the rapid development and limitations of VR exhibitions and proposes, as an alternative, the development of AR exhibitions. Studying VR/AR exhibitions that ran before and after COVID-19, this paper finds that VR, on the one hand, translates physical objects into digital video, which lacks aesthetic depth, and encounters operational problems originated by devices. By using mobile devices that are widely distributed and convenient to use, AR exhibitions can, on the other hand, be divided into three types: "museum-specific exhibitions" can present digital content in a specific indoor space, while "place-specific exhibitions" can be used in open outdoor spaces. The "non-place-specific exhibitions", can, as third type, combine digital content with printed material sent by postal mail. Among these three types, the specific/unspecified place type shows the highest "uncontact effect," which can suggest the best direction for effective museum content development in the pandemic era.
