This Study developed library of parts, applied with 3-dimension character which has width, length and height and a reference plane, for the system development of BIM design on housing unit modular. The current BIM software has not the concept of a reference plane or work tolerance in modular, so the development of parts library applied to unit modular has not moved forward. So, we developed, in this study, parts library applied to windows, built-in-furniture, kitchen systems and knock down bathrooms, with a reference plane and work tolerance based on single roon prototype on urban-life-housings. BIM library can utilize changed size and work tolerance of parts, and fabricating reference plane will be created automatically when an engineer puts work tolerance in the BIM library with supplement of some category related to work reference. Through this BIM library development, we consider the part module can be used for housing complex planning, and architectural designers will be able to utilize the BIM library for housing complex design.

The potential of nanocomposites have been drawing the intention of the researchers from energy storage to electrical insulation applications. Nanocomposites are known to improve dielectric properties, such as the increase in dielectric breakdown strength, suppressing the partial discharge (PD) as well as space charge, and prolonging the treeing, etc. In this review, different theories have been established to explain the reactions at the interaction zone of polymer matrix and nanofiller; the characterization methods of nanocomposites are also presented. Furthermore, the remarkable findings in the fields of epoxy, cross-linked polyethylene (XLPE), polypropylene and polyvinyl chloride (PVC) nanocomposites are reviewed. In this study, it was observed that there is lack of comparison between results of lab scale specimens and actual field aged cables. Also, non-standardization of the preparation methods and processing parameters lead to changes in the polymer structure and its surface degradation. However, on the positive side, recent attempt of 250 kV XLPE nanocomposite HVDC cables in service may deliver a promising performance in the coming years. Moreover, materials such as self-healing polymer nanocomposites may emerge as substitutes to traditional insulations.

Some conclusions can be derived from the study: 1. Person's name should be script by the one's mother tongue because of its uniqueness. 2. Japanese person's name should be script and pronounce their mother tongue for exchange and sharing of an academic information. 3. We can anticipate that Japanese language materials will be increase in near future. 4. The National Central Library which publish Korean National Bibliography must have to responsibility to lead other library. 5. The script of [Korean National bibliography] must contribute to standardization and national and Universal Bibliographic Control. 6. The area of education, newspaper, publishing are scripting Japanese person's name with script conversion schemes for Koreanization, devised by Ministry of Education. 7. The script of [Korean National Bibliography]'s name index can be used as authority file at selection of heading in library cataloging. 8. Most of libraries script Japanese person's name with Chinese character in Korean language pronunciation. 9. Korean Cataloging Rules (KCR) and Korean Machine Readable Cataloguing (KORMARC) description rules should be defined about the mother tongue script of Japanese person's name. 10. It is desirable to increase of credit of Readings in Japanese material course in college curriculum. 11. Because Japanese person's name is complex and variable that it is desirable to add Chinese character with mother tongue script.

Demand for organic analysis increase as industries are growing and many products are spreaded in the daily life. One of many products is oil spill dispersant. It was used for oil accident in the ocean. When oil spill dispersant spread at the ocean, the petroleum in the ocean is dispersed. The oil spill dispersant is made of non ionic surfactant and petroleum oil. The non ionic surfactant disperse petroleum from oil accident. The other part is petroleum oil which has aromatic hydrocarbon. Because the aromatic hydrocarbon is cancerogenic material, it directly injure animals in the ocean. This cause the second pollution in the human body. Many oil accidents still are controlled by oil spill dispersant. Therefore quality control of the oil spill dispersant become important and this also demand for the exact quantitative analysis of aromatic hydrocarbon. Hereupon the first we develop separate petroleum oil from surfactant. The second standardize analytical method of aromatic hydrocarbon in the separated petroleum oil.
