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.

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.

In 2014, Japan is scheduled to launch GCOM(Global Change Observation Mission)-C for the global change observation mission, where SGLI(Second-generation Global Imager) is planned for optical multi-channel observation ofa radiation budget and a carbon cycle. Depending on the spectral channels, SGLI consists ofS GLI-VNR(Visible Near IR) and SGLI-IRS(IR Scanning). Their main design schemes are mostly based upon those ofthe previous instruments ever developed in Japan, which is intended to reduce the development risk for the advanced performance. Accordingly, for the better understanding ofSG LI, the paper reviews the history oft he Japanese optical payloads from two different views: VNR and IR. Through the review, a comparison among the Japanese optical instruments is made to distinguish the development trend toward SGLI ofGC OM-C.

Understanding about the Nature of Science (NOS) is element of scientific literacy. Its importance is emphasized, especially understanding about NOS was presented as goal of science education on the fifth curriculum in Korea. Attempt of teaching NOS has been continuous in school, that was limited by method of using History of Science. Except method of using History of Science, Experimenting is appropriate for method of teaching NOS. We expected that is effective to apply reflective approach method for understanding the NOS and composite lesson to emphasize reflection and discussion to general experiment class in the school. We applied experiment class to emphasize reflection and discussion to second grade students in the middle school and researched whether positive reflection and discussion is helpful understanding the NOS in science experiment class or not, through questionnaire about NOS and analysis of observation and interview. As a result, experiment class to emphasize reflection and discussion was effective for scientific inquiry skills and sociality of scientific inquiry, particularly for relation observation with deduction and possibility of variable analysis to experiment result. Therefore, experiment class to emphasize reflection and discussion is effective for understanding the NOS.

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.
