Arrangement of individual atoms and molecules with atomic precision and understanding the resulting properties at the molecular level are ultimate goals of chemistry, biology, and materials science. For the past three decades, scanning probe microscopy has made strides towards these goals through the direct observation of individual atoms and molecules, enabling the discovery of new and unexpected phenomena. This talk will discuss the origin of forces governing motion of small organic molecules and their extended self-assembly into two-dimensional surface structures by direct observation of individual molecules using scanning tunneling microscopy (STM). In addition, atomic force microscopy (AFM) is utilized for the investigation of fundamental mechanisms of bone mineral dissolution by examining atomically well characterized simulated bone minerals under aqueous solution environments.

In order to obtain a clearer understanding on the evolution of Our Galaxy, we are currently undertaking a series of spectroscopic observation for few hundreds metal poor halo stars. As the first result, we present the chemical abundance measurements for 15 metal-poor dwarf stars in the solar neighborhood. The observation was made with the BOES #4-fiber, providing the effective resolving power R=32000. (omitted)

A Lunar observatory not only provides ideas and experiences for space settlements from the Moon to Mars, but also puts the telescope in an optimal position to compete with space telescopes. Earth observation on the Moon's surface has the advantage of no atmospheric scattering or light pollution and is a stable fuel-free observation platform, allowing all longitude and latitude of the Earth to be observed for a month. Observing the entire globe with a single observation instrument, which has never been attempted before, and calculating the global albedo will significantly help predict the weather and climate change. Spectropolarimetric observations can reveal the physical and chemical properties of the Earth's atmosphere, track the global distribution and migration path of aerosols and air pollutants, and can also help detect very small space debris of which the risk has increased recently. In addition, the zodiacal light, which is difficult to observe from Earth, is very easy to observe from the lunar observatory, so it will be an opportunity to reveal the origin of the solar system and take a step closer to understanding the exoplanet system. In conclusion, building and developing a lunar observatory will be a groundbreaking study to become the world's leader that we have never tried before as a first step in expanding human experience and intelligence.

The Tropical Rainfall Measuring Mission (TRMM) is an US-Japan joint space mission to observe tropical and subtropical rainfall. This satellite is equipped with the world's first precipitation radar that operates at 13.8 GHz. We introduce the TRMM precipitation radar (PR) system, along with the PR data processing and analysis algorithms, and some observation results obtained by the TRMM PR. It is concluded that the TRMM PR can give quite useful rainfall data for the understanding of global climate changes, meteorology, climatology, atmospheric science, and also for the studies of satellite communication.

COMS (Communication, Ocean and Meteorological Satellite) is a geosynchronous satellite and has been developing by KARI and Astrium for Ka-band communication, ocean observation and meteorological observation. COMS Chemical Propulsion System (CPS) uses a bipropellant propulsion subsystem, which is applied for transferring COMS from GTO to GEO (mission orbit) and implementing station-keeping manoeuvres. In this paper COMS CPS is briefly introduced for understanding. A few of mathematical thermodynamic modelings of bipropellant propulsion system in literatures are reviewed and authors has studied those models for developing a computer program, which predicts variations of thermodynamic properties such as temperature and pressure histories in the helium pressurant tank, MMH propellant tank and NTO propellant tank during LAE firing and on-orbit manoeuvrings. The CPS thermodynamic model may be used to compute pressurant and propellant masses and to size tank volumes.

People with visual impairments are difficult to go to education facility by themselves, because of their limited visual ability, orientation, and usability field, so they prefer dormitories. Those dormitories playa role in living space, education, communication and culture function. Therefore those facilities planned more user centered design, since they are influenced by user actability and their values. User centered designs that match between the user and space are understood as well as their characteristics and behavior. Especially for understanding their activity, observation is conducted about their behavior in dormitories. Thus the purpose of this study is suggested to be a basic source that planning about residential facility for people with visual impairments through interview and observation investigation by analysis that they resident in space motion and performance.

일본은 향후 2014년으로 발사가 예정되어 있는 GCOM-C를 이용하여 지구 복사량 및 탄소의 변화량, 해색정보, 에어로졸 분포 등을 측정할 계획을 추진 중이다. 특히, GCOM-C에는 SGLI-VNR과 SGLI-IRS로 구성되어 있는 SGLI를 탑재하고 있으며, 각각 가시영역/근적외영역과 적외영역의 영상을 측정하도록 설계될 예정이다. SGLI는 최신 성능을 갖춘 설계부분과 함께 기본적인 기능 및 구조 등은 지금까지 일본에서 개발되어진 여러 광학 탑재체들의 개발기술들을 바탕으로 구현됨으로써, 개발위험을 최소화 하는 전략을 취하고 있다. 본 논문에서는 지금까지 일본이 개발한 여러 광학 탑재체들의 특성들을 채널별(가시영역/근적외영역과 적외영역)로 비교 및 검토하면서, 향후 개발 완료될 SGLI의 특성을 이해하고 일본의 광학탑재체 개발 경향에 대한 분석을 수행하고자 한다.

과학의 본성에 대한 이해는 과학적 소양의 요소로서 그 중요성이 강조되고 있으며, 우리나라에서는 제5차 교육과정에 과학의 본성에 대한 이해가 과학교육의 목표로 제시되기 시작했다. 학교수업에서도 과학의 본성을 가르치려는 시도들이 이루어졌는데, 우리나라에서는 주로 과학사 소재를 수업에 도입하는 방법에 국한되어 진행되어 왔다. 이외에 과학의 본성을 가르치는데 있어 적합한 방법으로 실험수행을 들 수 있다. 또한, 반성적 접근 방법을 적용한 과학의 본성수업이 제안되고 있는데, 이것을 조합하여 현장에서 보편적으로 이루어지는 실험수업에서 실험에 대한 반성과 토의를 강조하면 학생들이 과학의 본성을 이해하는데 효과적일 것이라 예상하였다. 따라서 이 연구에서는 반성을 강조한 실험수업을 중학생들에게 적용하였고, 과학의 본성에 대한 설문지를 통해 과학실험 활동에서 적극적인 반성과 토의 과정이 과학의 본성의 대한 이해의 증진에 도움을 주는지 알아보았다. 연구 결과 반성을 강조한 실험수업은 관찰과 추론 관계, 자료 해석의 다양화, 탐구와 사회적 제반 상황과의 관련 영역에서 과학의 본성 이해에 특히 효과적이었으며, 그 외 과학적 탐구기능과 과학적 탐구의 사회성 모든 영역에 대한 학생의 이해에 효과적이었다. 연구 결과를 통해 반성을 강조한 실험 수업은 과학의 본성 이해에 효과가 있다고 말할 수 있다.

The purposes of this thesis lies in the study of marketable design through understanding of skiwear design and its market. This was done through the analysis of the present state of, and the growth of its market, modern fashion industry and the consumer, through skiwear related periodicals. I undertook the task of understanding current design trends through a study of catalogs by well-known ski wear brands, firsthand observation and photographing at ski resorts. The characteristics of present fashion industry lie in the realization of global merchandising, expansion of discount stores and tele-sales, demands for susceptible store interiors and change in consumer behavior. The market created outside of mainstream skiwear, focuses on the growth of the sportive mood over all areas of fashion, and among these developments. Skiwear trends begin to show tendencies to subdivide. Skiwear design can be divided into groups of functional sportswear for professionals, practical, snowboard-wear that combines as street-wear and finally elegant, feminine style.

Education is a key element in shaping the worldview of the next generation and determines society's core values, ideology, and basic understanding of human rights. While Kyrgyzstan is a secular state, Islamic education, backed by Arab and Turkish sponsors, continues to increase in popularity with the construction of thousands of mosques and dozens of new Islamic educational institutions. Young women have become an important target for Islamic ideology and Islamic educational institutions seek to introduce a new type of ideal woman who is obedient, submissive, and modest. This research uses curricula content analysis, participant observation, and in-depth interviews with teachers and students to examine the effects of newly introduced Islamic education institutions and concludes that the schools are succeeding in training female Kyrgyz students for sheltered lives of dependency, threatening to fundamentally erode women's rights in the country. Two tasks thus demand the attention of policymakers: preserving Kyrgyzstan's secular state and introducing new interpretations of the Quran, which strengthen support for women's rights among believers.
