This is a study on the origin of fashion imaging. First of all, 1 looked into the history of French fashion printmaking from late 16th century to early 19th century. Then studied the changes in the characteristics of context and form over the different periods and summarized each concept. At the same time, I looked into the process of fashion magazine evolving from fashion printmaking. In order to find out how fashion printmaking dealt with the characteristics of fashion media, 1 researched the commercial environment of fashion printmaking and reorganized the methodology of its media's role. Such analysis and results helped to reach a definition on how to regulate fashion printmaking. Fashion imaging was sparked by a small curiosity. As people began to be rage over new things, it came to introduce the fashion leaders of the public combined with the attributes of trend. At times when changes were so big that they were unpredictable, it itself became a fashion leader. Then a fashion creator emerges and it's function changes to that of a communication media. Moreover, the regular issuance of fashion printmaking implemented the concept of trend cycle and fashion imaging completely fulfilled the conditions of a communication media. The massive increase in the production of fashion printmaking and magazine contributed to the spread of fashion and the diffusion of printmaking lead to mutual complementation and synergy necessitated by fashion. Thus, the democratization of fashion and the commercialization of printmaking art occurred at the same time.

This study was intended to make a comparative analysis of the plastic features of Korean and Japanese dragon patterns found in the process of recreating traditions in comtemporary fashion based on the investigation into the style of expression in relation to the origin, formative evolution, symbolism and traditional costume of the dragon. The form of the dragon has evolved with some similarity and peculiarity between both countries and been changed into many kinds and diverse forms such as the humorous dragon pattern of the Yi Dynasty and the simplified and designed dragon pattern symbolizing the Japanese family crest and the like, Its symbolism has lasted in terms of the sacrificial object, royal power, good omen, Buddhist guardian and the like. There is a difference in the aesthetic sense due to the different traditions and cultural background between Korea and Japan, and the dragon pattern found in the process of recreating the tradition in comtemporary fashion manifested itself as the peculiar aspect. An attempt was made to make a comparative analysis of the dragon pattern found in comtemporary fashion between Korea and Japan. The following results were obtained: First, the commonality between both countries was to make a contemporary expression of the dragon pattern, which was expressed in a realistic form because of a traditionally inherent strong image of the dragon. On the other hand, the designed dragon pattern rarely found expression. It can be said that carefully treating the dragon pattern is attributed to the Oriental thinking like this. Second, Korean people have arranged one or more simplified dragon patterns taking on a form of the coiling dragon in the composition of the scattered point and made a comtemporary expression of them by the contrast of black and white shading in Korea. And the humorous form of the dragon pattern manifested itself in the Yi Dynasty. On the other hand, the case of printing the dragon pattern in the black dragon sword of all over the Kabuki costume in a pictorial composition has frequently appeared in Japan. And Japanese people have expressed its lightness and briskness rather than the dignity and strength that the dragon pattern gives with the use of strong color tones and new materials.

According to the Korean government's Long-term Space Development Plan 2040, "Creative space science research" is included in a statement to investigate the origin and evolution of the universe by conducting a series of Korean space telescope missions: launch of space telescopes on a small satellite and an international collaboration explorer by 2020, a mid-size domestic space telescope by 2030, and a large size Korea leading international space telescope by 2040. We studied the feasibility of the future Korean Space Telescope (KST) for a mid-size domestic satellite platform. In order to pursue the uniqueness of the science program, we consider a wide range of observing wavelength (0.2um ~ 2.0um) with a spectral resolution of R~6 in the NUV and optical bands, and R~30 for NIR, utilizing an off-axis TMS(Three Mirror System) optics with a wide field of view ($2{\times}4$ degrees) which is optimized for ultra-low surface brightness sources. The main science goals of the mission include investigations of the galaxy formation, cosmic web, and the cosmic background radiation in the NUV-NIR regions. In this paper, we present the science cases and several technical challenges to be resolved along with the future milestones for the success of the KST mission.

태양계 질량의 대부분은 플라즈마, 기체, 또는 액체 상태로 존재하며, 극히 일부만이 고체 즉 암석과 광물로 존재한다. 하지만, 반응 특히 혼합(mixing)이 일어나는 속도가 매우 느린 고체의 특성상 태양계의 탄생과 진화 과정의 기록은 고체태양계 물질에 더 잘 보관되어 있다. 지구를 제외한 고체 태양계 물질을 확보하기 위해서는 지구로 낙하한 암석인 운석(meteorites)을 발견하거나, 우주로 나가 시료를 가져와야 한다. 아폴로 미션(Apollo mission)에 의한 월석(lunar rocks) 채취(Papike et al., 1998), 하야부사 미션(Hayabusa mission)에 의한 소행성(asteroid) 시료 채취(Nakamura et al., 2011), 스타더스트 미션(Stardust mission)에 의한 혜성 시료 채취(Zolensky et al., 2006) 등이 후자에 속한다. 능동적으로 가져온 시료는 아직까지는 그 종류와 양에서 운석에 비해 매우 부족하므로 현재까지 우리가 알고 있는 고체 태양계에 관한 대부분은 운석 연구를 통해 얻어졌다. 운석은 크게 미분화운석 즉 콘드라이트(chondrites)와 분화운석(differentiated meteorites)으로 구분한다. 분화운석 중 일부는 달운석(lunar meteorites) 또는 화성운석(martian meteorites)이며, 나머지 분화운석과 콘드라이트는 암석-지구화학적 특징과 성인적 연관성에 의해 다양한 그룹으로 세분되는데 각 그룹은 하나의, 또는 둘 이상의 매우 유사한, 소행성에서 유래한 것으로 해석된다(Krot et al., 2014; 최변각 2009). 다양한 종류의 운석과 구성 광물에 포함된 기록으로는 (1) 태양계 이전 존재한 항성의 대기에서 생성된 광물, 즉 선태양계 광물(presolar grains), (2) 태양계 성운 탄생과 각 진화 단계의 정확한 시기, (3) 태양계 성운의 화학조성-동위원소 조성, 온도-압력 조건 등을 포함한 물리-화학적 특징, (4) 가스-먼지로부터 미행성, 소행성, 행성으로의 진화 과정, (5) 행성 진화의 열원, (6) 소행성 핵의 생성 과정 등이 있다. 강연에서는 이들을 간략히 살펴보고자 한다. 운석연구 등을 통해 태양계 생성과 진화과정에 관한 다양한 정보가 축적되었지만, 앞으로 연구할 것들이 더 많다. 또한 태양계 물질 중에는 운석의 형태로 지구로 들어왔거나 앞으로 들어올 수 있는 것도 있지만 그렇지 않은 것도 있다. 가스나 기체의 경우가 그러할 것이며, 고체지만 결합이 약해 일부라도 원형을 유지한 채 대기권을 통과 할 수 없는 것도 있을 것이다. 또 공전궤도나 중력 등 물리적 이유로 지구권 진입이 불가능한 것도 있다. 이러한 태양계 구성원에는 우리가 아직까지 얻지 못한 정보들이 다량 보존되어 있을 것이다. 미래의 태양계탐사가 기대되는 이유 중 하나이다.

The starting point of this study is the concerning of simple behavioral pattern that whoever enters the inner space with taking off his shoes should go out from the position where he laid his shoes. The using of Ondol (floor heating room) and Maru (lifted wood floor) had changed the architectural space from chair-sitting to floor-sitting space, and it also made the behavior of taking off the shoes at the entrance of building and stepping on the lifted floor. This simple behavior has possibility to make lots of changes to the culture of architectural design. With this noticeable point, this paper is talking about the cultural feature of Korean traditional architecture, especially about the influence of tanking off and putting on shoes. The matter of shoes has changed diverse aspects of building and layout planning. It maximized the difference between front and rear part of building and characterized the lateral extension of Korean traditional house. The ritual space also had evolved from chair-sitting to floor-sitting space according to the type of ritual behavioral pattern. The change on the single building level had influenced on the layout planning of architectural complex. For examples, the parallel layout of ChangDeok-gung palace and the long sequential process to the main pavilion of Buddhist temple are the result of the matter of shoes. And NuGak(樓閣), the double-storied pavilion, on the axis of entering sequence's node is one of the unique planning elements that makes possible to go through the building without taking off the shoes and also makes upper level space for staying. In short, Korean traditional architecture that has the chair-sitting spatial origin of the East Asian cultural sphere has pursued new architectural issues and planning methods according to evolution to the floor-sitting culture.

The novel swine-origin influenza A/H1N1 virus (S-OIV) first detected in April 2009 has been identified to transmit from humans to humans directly and is the cause of the currently emerged pandemic. In this study, nucleotide and deduced amino acid sequences of the hemagglutinin (HA) and neuraminidase (NA) of the S-OIV and other influenza A viruses were analyzed through bioinformatic tools for phylogenetic analysis, genetic recombination, and point mutation to investigate the emergence and adaptation of the S-OIV in humans. The phylogenetic analysis showed that the HA comes from triple reassortant influenza A/H1N2 and the NA from Eurasian swine influenza A/H1N1, indicating that HA and NA descend from different lineages during the genesis of the S-OIV. Recombination analysis ified the possibility of occurrence of recombination in HA and NA, denoting the role of reassortment in the outbreak. Several conservative mutations were observed in the amino acid sequences of the HA and NA, and these mutated residues were identical in the S-OIV. The results reported herein suggest the notion that the recent pandemic is the result of reassortment of different genes from different lineages of two envelope proteins, HA and NA, which are responsible for the antigenic activity of the virus. This study further suggests that the adaptive capability of the S-OIV in humans is acquired by the unique mutations generated during emergence.

We investigate regional differences in the characteristics of cold surges that occurred over the South Korea during winter season (December-February, 1981/1982~2017/2018). A significant regional contrast of cold surge characteristics exists and we found that this is closely related to the spatially inhomogeneous distribution of winter-mean climatological surface temperature in association with the complex topography of the Korean peninsula. For the regions of the temperature below -1℃ (Region1; R1), the frequency of cold surges is inversely proportional to the surface temperature almost linearly. In case of the regions above -1℃ (Region2; R2), cold surge frequency does not exhibit any clear dependency on the surface temperature. Duration and number of occurrences of cold surge between the two regions showed clear difference. Dynamical evolution of cold surges before the onset showed a sharp contrast between R1 and R2. In R1, cold surface air temperature (SAT) was already predominant over East-Asia before the onset and the cold temperature was sustained after the occurrence. On the contrary, warm SAT was predominant over East-Asia before the onset in R2. The SAT suddenly drops just after the cold surge occurrence. We present different origin of wave activity and propagation characteristics between the two types: Wave-activity flux (WAF) was relatively weaker and wave disturbances moved eastward in R1 along with the WAF mainly directing eastward. In case of R2, WAF was stronger and directing southeastward in the upstream of South Korea movement erasing predominant warmer air eventually causing sudden temperature drops over southern provinces over South Korea.
