At the beginning of 21st Century, human desire of communication is forwarding to the Cosmos The way of Communication is going to be not by simple methodology but by the complicated methodology with high technology. It will not be monologue communication but be interactive communication, that will make intelligence Infra, which could be able to communicate from the location of information is present to which is not present; and the multi-media which will be able to solve the technical problems of these communication; will be developed continually. In the genre of plastic art, there are no exception in these changedness. More developed and proceed to develope intermedia could be able of intercommunication. The more development of technology could be able to the more development of new plastic art. Furthermore the development of science make the genre of art to be changed. There are no exception of this changedness in any part of society, The art always has been guided by the person who has proceeding idea for new value. The 21st century plastic art will be in the procedure of the intercommunication. Human-being's concern is to communicate with Universe, and that will be multi-dimension$(4{\cdot}5{\cdot}6{\cdot}7{\cdots}dimension)$ communication beyond our usual recognition. To conjoin this, the possibility of cyber space expressing is going to be considered, and the way is being done by the development of the Media Art, which is able to go and back to the cyber-space. And the message will be so complicate beyond our recognition. Because we will need to communicate with various newly-built vocabulary, so we need to magnify the repertories of new vocabulary.

KASI (Korea Astronomy and Space Science Institute) is developing the near-infrared camera system named KASINICS (KASI Near-Infrared Camera System) which will be installed at the 60cm f/13.5 Ritchey-Chretien telescope of the Sobaeksan Optical Astronomy Observatory (SOAO). The camera system is optimized for JHKL bands and has a 6 arcmin FOV. The optical system consists of two spherical mirrors and a 8-position filter wheel. With the exception for the dewar window, all optical elements are cooled inside cryogenic dewar. Since the Offner system is adopted to prevent thermal noises from outside of the telescope primary mirror, the secondary mirror of the Offner system acts as a cold Lyot stop. The optical performance does not change by temperature variations because the Aluminum mirrors contract and expand homogeneously with its mount. We finished the design and fabrication of the optical parts and are now aligning the optical system. We plan to have a test observation on 2006 January.

Generally part of museum collections are cycled exhibition space centering around preservation space, and that is a important mechanism of collections circulation in a museum. The reason why with a few exception most of collections have been lasting its life during over hundreds of years with adapting itself to natural features, so scheme of preservation facilities should be made up with understanding and analysis generic character of collections, and then establish proper temperature and huminity environment. So, this study is based on a fact that the collections' physical and chemical conditions vary in the relics a degree of transforatiov. And by making a suitable ganering environment, this gradual study is to provide planning factors for an architectural guide to make museum ganering environment organized and resonable.

John Glenn, America's first man to eat anything in the near-weightless environment of Earth orbit, found the task of eating fairly easy. With improved packaging came improved food quality and menus. By the time of the Apollo Program, the quality and variety of food increased even further. Apollo astronauts were the first to have hot water, which made rehydrating foods easier and improved the food's taste. Thermostabilized pouches were also introduced on Apollo. The task of eating in space got a big boost in Skylab. It also had a food freezer and refrigerator a convenience offered by no other vehicle before or since. Two different food systems will be used for future long-duration missions to other planets, one for traveling to and from the distant body and one for use on the surface of the moon or Mars. The transit food system will be similar to the space station food system with the exception that products with three-to five-year shelf lives will be needed. Thus, this part of the trip will be similar to what occurs aboard space missions now. The surface food system, be it lunar or planetary, will be quite different. It will be similar to a vegetarian diet that someone could cook on Earth. Once crew members arrive on the surface and establish living quarters, they can start growing crops. Once the crops are processed into edible ingredients, cooking will be done in the spacecraft's galley to make the food items. Disposal of used food packaging will be an issue since there will be no Progress vehicles to send off and incinerate into the Earth's atmosphere. Packaging materials will be used that have less mass but sufficient barrier properties for oxygen and water to maintain shelf life as those now in use.

This study is mentioning about basic information and guide related block types, through a comparison and an analysis of floor types which is shown as function in block types and public interior spaces. For the range of this survey, it is defind in the beginning of 1970' s to the end of 1990' s which was rapidly developed in hotel industry and also is chosen by 12 places in the first class hotels. On the purpose of this study is written by designing the basic information of architectures, new hotels which are built and managed in urban, refer to the survey and analysis of the characteristic in hotel. The following is conclusion by based on pre-survey of the analysis of a plan and a site in these hotels. First, as a result of analysis in block type, there are equally distributed in three types (in-type, combination type, close-type), except a atrium type exception, in 12 hotels(100%). Second, as a result of analysis of function type in public interior space, Con-course type is consist of 7(58%), Hall type is 5(42%) in the type of room in public interior space, in 12 hotels(100%). Third, the type in lobby on space plan are equally shown by the type of lobby in center(4PL.), of lounge in center(4PL.), and a compromising type(4PL.).

We carried out a set of simulations to reproduce the performance of wide-field NEO surveys based on the revised population model of Near Earth Objects (NEOs) constructed by Morbidelli (2006). This is the first time where the new model is carefully compared with discovery statistics, and with the exception of population model, the simulation is identical to the procedure described in Moon et al. (2008). Our simulations show rather large discrepancy between the number of NEO discoveries made by the actual and the simulated surveys. First of all, unlike Bottke et al. (2002)'s, Morbidelli (2006)'s population model overestimates the number of NEOs. However, the latter reproduces orbit distributions of the actual population better. Our analysis suggests that both models significantly underestimate Amors, while overestimating the number of Apollos. Our simulation result implies that substantial modifications of both models are needed for more accurate reproduction of survey observations. We also identify Hungaria region (HU) to be one of the most convincing candidates that supply a large fraction of asteroids to the inner Solar System.

It is known that Chang-Hwa Park (1889-1962) transcribed a chronicle of the Goguryeo kingdom (BC 37-AD 668) of Korea (hereafter Goguri annal) from literature of the time that is no longer available. However, the authenticity of his transcription remains disputed. This study attempts to verify whether the Goguri annal is a pseudograph by analyzing the astronomical records in the annal. Although the Goguryeo kingdom fell in the year 668, the Goguri annal contains records up to the year 536. In this study, we have classified the astronomical records into eight categories and clustered them into two groups: a calendrical data group of reign-name and calendar date categories, and a celestial phenomena group of solar eclipse, trespass, comet, daylight appearance of Venus, meteor/meteorite, and other categories. The records of each category have been compared with those of the Samguksagi (History of the Three Kingdoms), Chinese chronicles, and with the results of modern computations wherever possible. From this comparison, we have not found any critical record that would indicate that the Goguri annal is a pseudograph, although the same astronomical records, with the exception of a few, are also found in the Samguksagi and Chinese chronicles.

This study mainly examined the unit space (room) called 'MARI' of the private houses that were built between the 19c and the early 20c in the insular areas of southwestern sea. Generally, this region has unique historicity (restructure of the insular environment in the 17c and the 18c) and geographic environment that are different from inland regions thus the environment is presumed as a related factor to developments and structures of the private houses. 'MARI' is a noticeable space that is installed in a main building without an exception even in small 3 bedroom private houses. Its nature has location and usage distinctions in an architectural plan with similar 'MARU' of inland Jeollanam-Do. There are large crocks filled with grains at MARI. Thus, MARI is a storage room. Mostly rice and various other kinds of grains are stored in the several crocks, large and small. Many household goods are kept here as well. Another peculiar function of MARI is that this space commonly enshrines ancestral tablets of three generations. Hence, MARI takes a role of a shrine of an aristocratic house from an inland region. Considering the size of the house and space, this seems to be a very unprecedented utilization of area. MARI is located at the top (at the head of the house) on the floor plan. In other words, it is located at the space in the highest rank. The importance of ancestor worship and grains is evinced architecturally. It is really interesting fact that MARI is also located within recently built modern houses (Cheongsan Island, Joyak Island, etc.). Therefore, it can be said that the unique MARI tradition of this region has an intact continuity even today. After all, MARI has a great significance as a unique unit space of insular areas of southwestern sea that is installed in the main buildings of all houses regardless of size and shape of the houses, and their insular locations.

We present near-infrared light curves of HBC 722 after its the September 2010 outburst. We have been monitoring its near-infrared light curves since November 2010 with Korean Astronomy and Space Science Institute Infrared Camera System (KASINICS). HBC 722 exhibits large changes in optical and near-infrared brightness since its outburst. The J, H, and $K_s$ light curves over about 2.5 years show that in all observed bands HBC 722 progressively became fainter until around April 2011, down to J ~10.7, H ~9.9, $K_s$ ~9.3, but it is getting brighter again. Large scatter in the obtained light curve prevents us from finding whether there is any short timescale variation as reported in other optical observations. The near-infrared color of HBC 722 is becoming bluer since its outburst. The pre-outburst Spectral Energy Distribution (SED) of HBC 722 is consistent with that of a slightly reddened Class II YSO with the exception of the extraordinary IR-excess in the far-infrared region.

We present the ALMA Cycle 2 results "Two New SiO Maser Sources in High-Mass Star-Forming Regions" which was published in the Astrophysical Journal (Vol. 826, P157, 2016). Silicon monoxide (SiO) masers are rare in star forming regions, with the exception of five known SiO maser sources. However, we detected two new SiO maser sources from infrared loud clumps of the high-mass star forming regions G19.61-0.23 and G75.78+0.34 using the KVN single dish. High angular resolution observations with ALMA and JVLA toward G19.61-0.23 suggest that the deeply embedded young stellar object (YSO) of SMA 1 is powering the SiO masers. In addition, the SiO v=1, J=1-0 line shows four spike features while the v=2 maser shows combined features of one spike and broad wing components, implying energetic activities of the YSO of SMA 1 in the G19.61-0.23 hot molecular core. The SiO v=0, J=2-1 emission shows bipolar outflows in NE-SW direction with respect to the center of the SiO maser source. A high angular resolution map of the SiO v=1, J=2-1 maser in G75.78+0.34 shows that the SiO maser is associated with the CORE source at the earliest stage of high-mass star formation. Therefore, the newly detected SiO masers and their associated outflows will provide good probes for investigating this early high-mass star formation.
