  • The First stars (Pop.III stars) in the universe are expected to be formed between the recombination era at z - 1100 and the most distant quasar (z - 8). They have never been directly detected due to its faintness so far, but can be observed as a background radiation at around 1${\mu}m$ which is called the Cosmic Near-Infrared Background (CNB). Main part of the CNB is thought to be redshifted Lyman-alpha from gas clouds surrounding the Pop.III stars. Until now, the COBE (COsmic Background Explorer) and the IRTS (Infrared Telescope in Space) observed excess emission over the background due to galaxies. To confirm the COBE and the IRTS results and pursue more observational evidences, we carried out the sounding rocket experiment named the Cosmic Infrared Background ExpeRiment (CIBER). The CIBER is successfully launched on July 10, 2010 at White Sands Missile Range, New Mexico, USA. It consists of three kinds of instruments. We report the results obtained by LRS (Low Resolution Spectrometer) which is developed to fill the uncovered spectrum around 1${\mu}m$. LRS is a refractive telescope of 5.5 cm aperture with spectral resolution of 20 - 30 and wavelength coverage of 0.7 to 2.0${\mu}m$. After subtracting foreground components (zodiacal light, integrated star light and diffuse galactic light) from the sky brightness of observed five fields, there remained significant residual emission (even for the lower limit case) consistent with the IRTS and the COBE results. In addition, there exists a clear gap at 0.7 - 0.8${\mu}m$ in the CNB spectrum over the background due to galaxies according to recent results (Matsuoka et al. 2011; Mattila et al. 2011). The origin of the excess emission could be ascribed to the Pop.III stars with its active era of z = 7 - 10.

  • Whitehead's discussion of language is not to be found in any one book or article. It is interwoven with his discussion of many other questions. He was, however, greatly concerned with the problem of symbolism in general and the uses of language. He regards language, spoken or written, as an instrument devised by men to aid them in their adjustment to the environment in which they live Language is used for many specific purposes in the process of this adjustment. Words are employed not only to refer to data and to express emotions. They may be used also to record experiences, and thoughts about these experiences. Worts also function as instruments in the organization of experiences as they are considered in retrospect. Thus words free us from the bondage of the immediate. And Whitehead's theory of meaning is implicit in his discussion of the functions of language. According to him, the human mind is functioning symbolically when some components of its experience elicit consciousness, beliefs, emotions, and usages, respecting other components of its experiences. The former set of components are the 'symbols', and the latter set constitute the 'meaning' of the symbols. Whitehead points out that one word may have several meanings, i.e. refer to several different data. In order to understand, thus, the meaning to which a word refers, it is sometimes very important to appreciate the system of thought within which a person is operating. Further, Whitehead's discussion of language includes a number of cogent warning the deficiencies of language, and hence the need for great care in the use of words. In fact, language developed gradually. For the most part we have created words designed to deal with practical problems. Attention focuses on the prominent features in a situation, in particular the changing aspects of things. With reference to such data our words are relatively adequate. However, this issues in an unfortunate superficiality. The enduring, the subtle, the complex and the general aspects of the universe do not have adequate verbal representation. for this reason, Whitehead's position concerning the uses of language in speculative philosophy is stated with pungent directness. The uncritical trust in the adequacy of language is one of the main errors to which philosophy is liable. Since ordinary language does not do justice to the generalities, profundities and complexities of life, it is obvious that philosophy requires new words and phrases, or at least the revision of familiar words and phrases. Proceeding to develop the theme Whitehead contends that words and phrases must be stretched towards a generality foreign to their ordinary usage. In the same vein Whitehead refers to the need to realize that language which is the tool of philosophy needs to be redesigned just as in physical science available physical apparatus needs to be redesigned. But even these words and phrases, stretched or redesigned, are never completely adequate in philosophical speculations. They are, in his opinion, merely a great improvement over ordinary language or the language science, mathematics or symbolic logic.

  • The NISS (Near-infrared Imaging Spectrometer for Star formation history) is the near-infrared spectro-photometric instrument optimized to the Next Generation of small satellite series (NEXTSat). To achieve the major scientific objectives for the study of the cosmic star formation in local and distant universe, the spectro-photometric survey covering more than 100 square degree will be performed. The main observational targets will be nearby galaxies, galaxy clusters, star-forming regions and low background regions. The off-axis optics was developed to cover a wide field of view ($2deg.{\times}2deg.$) as well as the wide wavelength range from 0.95 to $2.5{\mu}m$, which were revised based upon the recent test and evaluation of the NISS instrument. The mechanical structure were tested under the launching condition as well as the space environment. The signal processing from infrared sensor and the communication with the satellite were evaluated after the integration into the satellite. The flight model of the NSS was assembled and integrated into the satellite. To verify operations of the satellite in space, the space environment tests such as the vibration, shock and thermal-vacuum test were performed. The accurate calibration data were obtained in our test facilities. Here, we report the test results of the flight model of the NISS.

  • SNe light curves have been used to understand the expansion history of the universe, and a lot of efforts have gone into understanding the overall shape of the radioactively powered light curve. However, we still have little direct observational evidence for the theorized SN progenitor systems. Recent studies suggest that the light curve of a supernova shortly after its explosion (< 1 day) contains valuable information about its progenitor system and can be used to set a limit on the progenitor size, R*. In order to catch the early light curve of SNe explosion and understand SNe progenitors, we are performing a ~8hr interval monitoring survey of nearby galaxies (d < 50 Mpc) with 1-m class telescopes around the world. Through this survey, we expect to catch the very early precursor emission as faint as R=21 mag (~0.1 Rsun for the progenitor). In this poster, we outline this project, and present a few scientific highlights, such as the early light curve of SN 2015F in NGC 2442.

  • In the perspective of the correspondence of heaven and man[天人相應], people live through Gi of heaven and earth[天地之氣], and the human body which is a small universe[小宇宙] itself receives influence while sympathizing with the Gi and heaven[天氣]. So with unexpected incident of the Eum and Yang, four season[陰陽四時], ups and downs of warmth of cold and chilliness of warm[寒熱溫涼] differs, and the position of Gi of human[人氣] changes, regimen and application of acupuncture, and images[象] of the pulse changes. In "Maekyojeongmiron(脈要精微論)", ups and downs of Eum and Yang changes by four season[四時], and correspondence of ups and downs of pulse law is explained with compass, carpenter's square, the beam of balance and the weight of balance[規矩權衡]. Compass[規] is a measure of instrument that can draw a circle, like regulating the measure and differing the center of the circle and diameter and drawing a circle, compass is a image of Gi of Yang[陽氣] that was staying deep inside the body in winter stretching out by big fault[太過不及] of year and energy[元氣] of human in spring. Carpenter's square[矩] is a instrument that draws direction, which is a image of Gi of Yang flourishing in summer and when it gets highly flourished, again the Gi of Eum[陰氣] comes alive and falls. The beam of balance[衡] is a scale, like a scale that tilts at once when one side is slightly heavy, the beam of balance is a image Gi of yang that is fully flourished in summer and about to descent again, which is just about to fall but not going down yet. The weight of balance [權] is a image of gi of yang which as descent to the bottom and staying in the deepest place. compass, carpenter's square, the beam of balance and the weight of balance is not a direct pulse image[脈象], but standard image of pulse of pulse corresponding to the Gi of human[人氣] that changes by four season, and the explanation includes the pulse image of four season like the taut, full, floating, deeply gather[弦鉤浮營] of "Okgijinjangron(玉機眞藏論)" or taut, full, skip, float, deep [弦鉤代毛石] of "Pyeong-ingisangron(平人氣象論)". So with compass, carpenter's square, the beam of balance and the weight of balance, can judge is human correspond in Eum and Yang, four seasons, this is importantly used in examination of pulse[診脈] with existence and nonexistence, and prognosis of illness.

  • 만화와 종국적으로 애니메이션은 환상적 시나리오 시각화의 효과적인 방법이다. 본고 에서는 어떻게 애니메이션이 미래 현재(변모되어가고 있는 인공두뇌, 매개 사회) 아주 흔한, 그리고 필수불가결한 부분을 차지하게 되었는지 알아볼 것이다. 따라서 애니메이션은 인터페이스이거나 혹은 대변자로서 일시적 형태의 대상인 인간과 현실의 담화형태가 된다. 애니메이션 혹은 특히 애니메이트된 필름은 보통 단편, 실사영화, 픽션이나 논픽션의 캐릭터와 연결되어있다. 하지만 애니메이션은 전통적 영화 형식과 언어와는 거리가 있고 같은 이유로 디자인과 커뮤니케이션 역시 다른 영역으로 구분된다. 하지만 $Vil{\acute{e}}m$ Flusser에 따르면 그렇지 않다. 같은 전제가 네트워크 문화 속 애니메이션에 적용된다. 애니메이션은 디자인 과정과 제작에 본질(모션 그래픽이나 인터페이스 디자인 그리고 3D 영상작업 등)로 자리한다. 비디오 게임, VR, map 기반 app과 소셜 네트워크 등은 확장된 우주인 우리의 네트워크 기반 문화에 자리하는 것으로 여겨진다. 이러한 것들은 애니메이션과 연결성이 증대된(세계공통어가 디지털 환경 속 멀티-컬처 상호작용에 적용된 것처럼) 디자인 제품과 미디어 훈련이다. 이러한 감각에서 애니메이션은 담론화 되었으며 같은 방법으로 Roland Barthes는 담화 형식의 신화를 묘사한다. 디자인 도구로서의 애니메이션 역할을 탐구하는 목적으로, 제안된 연구는 애니메이션을 사용하여 트렌스 미디어 창작의 이미지 전략을 네러티브와 유저 인터페이스 측면에서 발전시키고자 하는 것이다.

  • After study about the shapes of Jung, Gi, Sin, Hyul-kwa advocated by Master Jisan, the conclusions are drawn as follows. It pursues the rules of universe being changed from formless to concrete objects that the Body Essence, Vital energy, Mentality, and Blood are materialized to Jung, GE, Sin, Hyul-kwa. It can be drawn an inference from the next three theories that Jisan considered Jung, Gi, Sin, Hyul-kwa as round, square, reverse triangle, and triangle or oval shape. First, it was taken to following the shapes of viscera. Namely Jung-kwa was taken as Kidney, Gi-kwa as Lung, Sin-kwa as Heart, Hyul-kwa as Liver. Second, it was adopted from five kinds of constitutions according to the five elements in [Yeongchu Yin and Yang twenty five shapes] that is Jung-kwa is purchased with Water-earth phases, Gi-kwa with metal phase Sin-kwa with fire phase, Hyul-kwa with Wood phase, Third, it is taken in order to eliminate contradictions. Hyul-kwa disliking to move is assumed to round shape to easily move. Gi-kwa tending to disperse is chosen to square in order to be unmoved. Sin-kwa declining to stagnate of seven emotions is pursued to reverse triangle to compose oneself. Hyul-kwa inclining to gather is preferred to acreage phase to harmonize ascending tendency. Among shapes which Jisan was divided Hado, Nakseo, Bokhee pal kwoe, Moonwang pal kwoe, Jung-kwa as round is Hado, Gi-kwa as square is Nakseo, Sin-kwa as reverse triangle is Bokhee pal kwoe order shape, Hyul-kwa as acreage phase or oval shape is accord with Moonwang pal kwoe order shape. The reason being classified into Jung, GE, Sin, Hyul-kwa from the shapes of the face is that the face is the place to reflect the whole conditions of the body connected with all of the viscera and meridian system such as semen of plants. Above contents are drawn an inference from the transcription of Jisan's lectures and his writings. And it is considered that insufficient parts of the Jisan's theory must be demonstrated continuously.

  • Hado(河圖) and Laks${\u{\lrcorner}}$(書洛) are the diagrams composed of the symbols of numbers from one to ten. And the eight-trigrams, P'al-gwoe divide into two types one is a priori eight-trigrams (先夭八卦) or the Bok-Hui's eight trigrams(伏羲八卦); and the other is a posterior eight trigrams (後夭八卦) or the king Mun's eight trigrams (文王八卦). Relating these two diagrams of Hado and Laks${\u{\lrcorner}}$ with the two types of eight trigrams, they are said to be a term of Ha-Lak-Hui-Mun (HLHM). Each of HLHM represents the process of creating and changing of 'heaven and Earth' and every beingby the symbols of numbers and trigrams. In other words, each of HLHM symbolizes the origin and the structure of the universe as well as the birth of every life represented in the diagram of theosophany (福智學) or Kabbalah. HLHM are also regarded as the origin of l-ching or Book of Change. Hado produces Laks${\u{\lrcorner}}$ through the principle of yin-yang(陰陽). Laks${\u{\lrcorner}}$ produces a priori eight trigrams through the zigzag shapes which means Heaven and Earth are mutually responding. And a priori eight trigrams produce a posteriori eight trigrams through the triangle principle of connecting Heaven and Earth. In this process, Hado and a priori eight trigrams are respectively prior to Laks${\u{\lrcorner}}$ and a posteriori eight trigrams. HLHM represent fractal shape resembling the symbol of five on the center of Hado, or Hado itself. In the dynamic process of HLHM, a diagram of Circle, Quadrangle, and Triangle (CQT) is produced as follows: Circle, the symbol of 'infinify' or Heaven, represents the origin of life or birth. Hadois the symbol of creation. Quadrangle, the symbol of Earth, represents that Laks${\u{\lrcorner}}$is scattered into four directions of front, back, left, and rifht. Quadrangle, which is immovable, represents materiality. Triangle, being described from the eight trigrams, means the movements of the process of 'mutual inclusion' of Circle and Quadrangle. Triangle also means the process of harmonizing human beings with natural law.

  • 본 연구는 선행연구에서 정립된 서비스철학을 기반으로 신경영학 프레임워크를 제시하기 위해 수행되었다. 대립되는 힘들 간의 치열한 대대원리 및 변증법적 과정과 상반상성이 서비스철학의 중심이므로 신경영학의 구조와 방법론은 이러한 철학적 기반을 반영하여 구축되었다. 현대경제사회변화를 반영하고 기존 경영학의 문제를 해결하는 경영학 체계를 제시하였다. 현대경제사회의 거시적 변화와 미시적 변화를 모두 분석하여 신경영학 체계정립에 반영하였다. 학문으로서의 기존 경영학의 본질적인 문제와 실무적인 문제를 분석하였으며, 문제 해결책으로서 신경영학을 제시하였다. 신경영학은 본질학문으로서 위상을 가져야 하므로 인류사회를 움직이는 공통원리에 부합해야 한다. 인류가 살아가는 환경인 우주의 원리와 인류의 생명원리를 분석하여 반영하였고, 인류대표사상과 예술원리도 분석하여 신경영학 체계 구축에 반영하였다. 이러한 공통원리를 도출한 결과 경영학의 본질 학문으로서의 자격 요건이 정의될 수 있었고, 경영학의 학문적 체계는 3을 사용하는 것이 진리에 가까움을 발견하였다. 따라서 신경영학 체계는 3개의 분야로 구축된다. 경영철학, 경영자론, 경영기술 등의 3개 분야가 경영학을 구성하는 하위분야가 된다. 경영철학은 경영과 경영학에 대한 사상적 기반을 연구하는 분야이며, 경영자론은 경영의 주체로서의 경영자와 경영의 객체로서의 경영자를 탐구하는 분야다. 경영기술은 그동안 경영학의 중심 분야였던 경영과정론, 경영기능론 등이 모두 포함된다. 신경영학의 각 분야에 대한 세부 구조를 정의하고, 주요 탐구 주제를 제시하였다. 향후 경영학을 본질학문화하기 위한 심화연구가 필요하며, 세부 분야의 이론 구축에 대한 연구도 필요하다.
