This study aims to provide better service to customers and to work out marketing strategies for making 6C(contents, communication, commerce, community, connection, customization), through comparing and analyzing official web site of the domestic professional sports teams. The web sites should develop various good quality of information and to increase the user's satisfaction. The web sites of satisfaction to increase your teams loyalty. The loyalty is very important things for business and operating teams. And then, the develop of web sites for user. However tired you may be, you must it. Sometimes user conflicted of the web site which not enough contents, commerce so on. There are mistaken. Not that sports teams disliked the operated web sites, but that sports teams no cognition for web site. This study to meet the purpose, was made through investigated of books and official web sites. The objective of this research is for you to click the internet order site 'www.rankey.com' for high position the sports web sites. And more, using the other article. As a result, the web sites of the sports teams have a lack of contents and commerce, community, however, construction of shopping mall with low cost and new technological development. Firstly, users very important to communication in quickly response to BBS, Q&A. And then, user to solved of his question and trouble, conflict. Secondly, the web sites develop the contents for user and customers of enjoy. Thirdly, the web sites include of community for customization and communication with marketing targets. Fourthly, in this study, the satisfaction of sports web sites develop on game informations for users. The user wanted to information of player news and game news for enjoyed himself. So many people wanted to different of other web sites and contents. Finally suggestion, connection of the other web sites for sports teams have a lack contents and information.

The purpose of the study was to undertaken to analysis the Grab starting technique between national representive team(3) and Cheju's representive team(3) with 3D cinematography. The conclusions obtained were as follows: Cheju's showed more elapsed time than national representive team on starting block. and more vertical than horizontal direction of COG position, more concentrated vertical velocity & acceleration than forward direction. Therefore It is necessory for cheju's to train balanced trust force in horizontal and vertical direction in grab starting technique.

<P>Two-dimensional (2D) graphene sheets have become a versatile platform for the fabrication of innovative hybrid materials with various functions due to their unique electrical, optical, thermal, and mechanical properties. The preparation of graphene-based composites with nanoscale precision is highly important for reproducible and controllable performance through the analysis of interplay between each component. In particular, the layer-by-layer (LbL) assembly technique is known as a simple, inexpensive, and versatile process for the fabrication of highly ordered multilayer film structures from various types of materials. The LbL structures capable of controlling nanoscale composition and architectures are achieved through the sequential adsorption of oppositely charged components by attractive forces such as electrostatic interactions. In this review, we will focus on the recent progress in graphene-based nanocomposites hybridized with various nanomaterials such as carbon nanomaterials, polymers, and inorganic nanoparticles by the LbL assembly. Multilayered graphene nanocomposites exhibit improved physical/chemical properties and superior performance compared with the individual components due to the synergistic effects in various applications including electric devices, energy storage and conversion, and biological usages.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/cmatex/2015/cmatex.2015.27.issue-11/acs.chemmater.5b00491/production/images/medium/cm-2015-00491c_0013.gif'></P>

Critical heat flux (CHF) is the thermal limit of a phenomenon in which a phase change occurs during heating (such as bubbles forming on a metal surface used to heat water), which suddenly decreases the heat transfer efficiency, thus causing localized overheating of the heating surface. The enhancement of CHF can increase the safety margins and allow operation at higher heat fluxes; thus, it can increase the economy. A very interesting characteristic of nanofluids is their ability to significantly enhance the CHF. Nanofluids are nanotechnology-based colloidal dispersions engineered through the stable suspension of nanoparticles. All experiments were performed in round tubes with an inner diameter of 0.01041 m and a length of 0.5 m under low pressure and low flow (LPLF) conditions at a fixed inlet temperature using water, 0.01 vol.% $Al_2O_3$/water nanofluid, and SiC/water nanofluid. It was found that the CHF of the nanofluids was enhanced and the CHF of the SiC/water nanofluid was more enhanced than that of the $Al_2O_3$/water nanofluid.
