The oil consuming country, Korea is spending amount to 220bn barrel per day. It is higher-ranked as 8th country among oil consuming country. France, Brazil, Italia, Spain have recorded GDP than it of Korea. But, the oil consuming of Korea is more than it of them. The GDP of Korea is ranked 11th country, based on 2005. But Korea is higher-ranked as 8th country among oil consuming country. The new and renewable energy as alternative of oil is first measurement. But, the supply of new and renewable energy is inactive 2.13% among total energies. The economist prospects about 1bn job creation during the ten years through new and renewable energy. The merit of new and renewable energy is capital intensive and higher valuable industry.

This paper describes qualities of a library classification system that are commonly discussed in the LIS tradition and literature, and explains such a system’s three main functions, namely knowledge mapping, information retrieval, and shelf arrangement. In this vein, the paper states the functional requirements of bibliographic classifications, which broadly are subject collocation and facilitation of browsing the collection. It explains with details the components of a library classification system and their functions. The major components are schedules, notations, and index. It also states their distinguished features, such as generalia class, form divisions, book numbers, and devices for number synthesis which are not required in a knowledge classification. It illustrates with examples from the WebDewey good examples of added features of an online library classification system. It emphasizes that institutional backup and a revision machinery are essential for a classification to survive and remain relevant in the print and e-environment.

This paper presents an architecture for distributed control systems and its underlying methodological framework. Ideas and concepts of distributed systems, artificial intelligence, and soft computing are merged into a unique architecture to provide cooperation, flexibility, and adaptability required by knowledge processing in intelligent control systems. The distinguished features of the architecture include a local problem solving capability to handle the specific requirements of each part of the system, an evolutionary case-based mechanism to improve performance and optimize controls, the use of linguistic variables as means for information aggregation, and fuzzy set theory to provide local control. A distributed traffic control system application is discussed to provide the details of the architecture, and to emphasize its usefulness. The performance of the distributed control system is compared with conventional control approaches under a variety of traffic situations.

A biochemical characterization of the tannases from Paecilomyces variotii (produced at Unicamp), Aspergillus niger (purchased from Industrial Kerry Bio-Science) and A. niger cnpat 001 (purchased from Embrapa Agroindustrial Tropical-Brazil) was carried out. P variotii is a new strain obtained from the screening of 500 fungi that were tested for their production of tannase. The biochemical properties of this new tannase from P variotii were determined and compared with those of two other tannase preparations. The tannase produced from P. variotii showed optimum activity at pH 6.5. The functional temperature range of the tannases was from $20-70^{\circ}C$, with optima at $70^{\circ}C$ for P. variotii and at $60^{\circ}C$ for the commercially obtained tannase, whereas A. niger cnpat 001 showed optimum activity at $40^{\circ}C$. The effects of 1 mM preparations of cations and anions, inhibitors, surfactants, and chelators on the tannase activity from P. variotii were also studied.

Natural fiber-filled polymer composites have attracted great interest due to increasing environmental concerns and their low costs. In this study, the properties of rice husk flour-filled polypropylene (PP) were analysed in view of the large quantities of this agricultural product available as residue in Brazil. The rice husk flour (RHF) was characterized by SEM and particle size distribution. The properties of the composites were studied by MFI, DMA, DSC and TGA analyses. A commercial PP modified with maleic anhydride (MAPP) was used as coupling agent. It was verified that RHF decreased the MFI of the composites and that the coupling agent decreased it even more. The efficiency of MAPP was confirmed by the high storage modulus and high loss factor of the coupled composites.

The last years have seen a dramatic increase of the new-building orders for Very Large Ore Carriers(VLOC), mainly driven by the increasing demand for iron ore imports from Australia and brazil to the steel mills in china. Thus the vibrant research of VLOC aimed cost-cutting by optimum compartment have conducted in recent years. In this study, we are also trying to find ways to reduce longitudinal strength by optimum compartment and check additionally whether the modified compartments were satisfied with SOLAS bottom damage.

In this paper graphical exploratory data analyses are proposed for ball games in sports. The plot of sequence of scoring points of each team can be used to see how the playing game has been processed until the end of each set or quarter. With the plot of sequential score differences through all the games we can see a dominance of each team and the times of score changes, i.e., turnovers. The ternary plots show the contours of scoring compositions for each player and enable us to compare the scoring patterns of each team if any. Using the score sequence plot we also can see the score pattern distribution of players. For demonstration we use the results of the gold medal match between Russia and Brazil for men's volleyball and between USA and Spain for men's basketball at the London 2012 Summer Olympics.

A disdrometer has been used to determine Z-R relationships for the weather radar, which is unique coastal radar operating regularly in western tropical south Atlantic. Rainfall rates were divided into the stratiform rain and the convective rain on the basis of $10\;mm\;h^{-1}$. The Z-R relationship for the stratiform class was similar to the general one since the convective clouds did not developed and two classes of the rain rate were mixed.

The introduced spider crab Pyromaia tuberculata was collected from Korea in 2005 and it was ovigerous. After hatching, larvae were reared in the laboratory at $20^{\circ}C$. The larval stage of the species consists of two zoeal and one megalopal stages. The larvae of the Korean species differ somewhat from those from New Zealand described by Webber and Wear (1981; N Z J Mar Freshwat Res. 15:331-383) and from Brazil described by Fransozo and Negreiros-Fransozo (1997; Crustaceana. 70:304-323.) in the setal presence of the antennule, the maxillule, the maxilla and the maxillipeds, and the abdomen. It is found that Fransozo and Negreiros-Fransozo have overlooked some setae on the basis of the zoeal maxillipeds and that re-examination of their larvae is needed. Also, it is found that the Inachoididae is heterogeneous based on the zoeal morphology because two distinct groups exist in the family.

The Zika virus, which is a member of the flavivirus genus, poses a serious threat to humanity because there is no vaccine or cure. Zika is suspected to cause microcephaly, and it is rapidly spreading throughout parts of Brazil. Surprisingly, there are no known protein structures for the virus which are essential for drug and vaccine development. This paper investigates the Zika virus's nonstructural proteins with template-based modeling by using GalaxyTBM/Refine/SC. GalaxyDock was used to examine the effectiveness of various known serine protease inhibitors in inhibiting the Zika viral protease. In testing five inhibitors, Kunitz soybean trypsin inhibitor showed the strongest binding affinity (-10.082 kcal/mol). This paper provides a rudimentary foundation for further drug discovery research regarding the Zika virus.
