At present, hydrogen is emerging as a future energy source based on environment-friendly aspect, creation of new industry, and enhancement of domestic energy security. In accordance with it, the world's leading automobile companies are focusing on the development and commercialization of hydrogen electric vehicle technology, and each country is strengthening its hydrogen fueling station deployment strategy for its own country. Furthermore, the supply of hydrogen fueling stations is actively promoting under national support. More than 500 hydrogen fueling stations are being constructed, operated and planned around the world. The introduction of hydrogen energy is also progressing in Korea, by announcing road-map to supply hydrogen electric vehicles and hydrogen fueling stations by year. However, there is insufficient discussion on the capacity of hydrogen fueling station in Korea. Therefore, this study suggests the optimum capacity of hydrogen fuelling station for domestic hydrogen economy.

This paper briefly charts the history of excrement as part of the late 20th-century art and explores ways in which excrement functions in the realms of 'High' art. From Piero Manzoni's to David Hammons' performance , excrement has taken a small yet distinctively important part in the development of contemporary art. In an attempt to challenge the hegemony of 'high' art, on the one hand, and resist the commercialization and fetishization of art, on the other, Manzoni allegedly offered his own "shit" preserved in a tin can and sold it at the price of gold of the same weight. Andy Warhol took the legendary Abstract-Expressionist painter Jackson Pollock as the object of parody, simulating Pollock's dripping action by pissing onto the canvas that had been primed with copper-based paint. Warhol's urination produced splashes and stains of iridescent colors just as the patterns on ordinary abstract paintings. In contrast to Pollock's masculine action, Warhol's pissing alludes to the artist's homosexuality. Excrements in art also provoked controversies, debates, and even acts of vandalism against the artworks. The works of Andres Serrano and Chris Ofili infuriated many Christians for the blasphemous use of excrement with religious icons. Politicians engaged in the heated debates on the use of public and national funds in support of some of the 'politically incorrect' contemporary art. In the midst of media sensation and criticisms, these works challenged the conventional understanding of artistic beauty. The preexisting artworks were also targeted. African-american artist Hammons assumed the role of spectator in by urinating on Richard Serra's sculpture in the street of New York City. It was an act condemnation levelled at the racist pattern of the way in which large portions of funds and commisions of "public" art tended to promote established 'white' artists, whose work or creative process often failed to reflect the actual public. The use of excrement in art is not unusual in contemporary art practices. With its subversive power, excrement plays an important critical roles in the shaping of contemporary art.

Purpose Consumption behaviors of consumers have changed with the widespread use of the Internet and smart phones, and accordingly online marketing activities are becoming ever more prevalent. Yet, the domestic food-service industry has yet to offer an Omni-Channel order system that encompasses a online, offline, and mobile interface. Also, a multilingual menu ordering service for foreign tourists is not yet available. Therefore, if an order service system accessible online and offline which could provide multi-language services were implemented, the satisfaction of the service provider and domestic and foreign customers would be maximized. Design/methodology/approach By designing an electronic menu based on open an OS and providing electronic menus in offline stores, we have completed the design of a linked order system which would be available everywhere (online, offline, and mobile). The CMS was developed to integrate these three mediums and the entire operator was designed to receive basic information and statistical information about the merchants, or store operators. Also, a multilingual term dictionary containing menu information for foreign tourists was made into a database so that foreign tourists who are having difficulty in communication can use it more easily. Findings We have made it possible for customers to use the order service without distinction between online, offline, and mobile platforms, and have proved that it is a more efficient and convenient service for customers as well as operators. Nevertheless, as an initial model, the implemented system has limitations on the execution of the payment support method in the electronic menu board and in the management division of the CMS. In case of commercialization, it is necessary to make an alliance of efforts to attract initial franchises. Through further supplementation, we expect the online and offline connection-types martservice system will maximize the satisfaction of both operators and customers alike.

A novel multi-valent salt based on polyethyleneimine having molecular weight of 800 (PEI 800) has been synthesized and characterized as forward osmosis draws solute. A reaction intermediate was synthesized by the neutralization reaction of polyethyleneimine and methyl acrylate, and was hydrolyzed with potassium hydroxide to synthesize a water soluble carboxylic acid (potassium salt) polyethyleneimine. NMR spectrometry, viscometry measurements and osmometry measurements was performed to characterize the draw solute. Forward osmosis experiments were done to know whether the solute could be used as a draw solute or not. The result shows comparable water flux and lower reverse salt flux compared with NaCl as a draw solute. We have also demonstrated recycling of the draw solute in the FO-NF integrated process.

The rapidity at which industrial and business management environment has become globalized, including the FTA, has provided valuable opportunities for domestic small and medium enterprises (SMEs) to obtain global technological business. However, it is unclear whether or not the SMEs' attempt to advance global technological business is producing fruitful results. This study begins with defining global technological business and the efforts of SMEs to develop them and proceeds to discuss survey results that asked the reasoning behind SMEs that entered or wish to enter foreign spheres (China, Japan, Southeast Asia, and Europe) of businesses, and also perform factorial analysis to obtain substantiation. The study classified the relevant SMEs using clustering method. Based on the results, the study makes recommendations to executives in instilling global-minded strategies, on customized support strategies depending on the SME's capability and its intended foreign entry sphere, and on strengthening the SME's competence on the global scale.

Subjects in this study comprised of general public (907), high school students (772), individuals associated with Oriental medicine (660), and 60 majoring in western medicine, totalling 2,413 individuals. Survey was conducted on the necessity of establishing Oriental medicine school at the national university level and the following result were obtained: - 78.3% (1847 individuals) were in favor of establishing Oriental medicine school at the national university level. - For the validity of establishment, responders expressed opinions of standard and virtuous education, higher quality education, standardized practice, research on difficult to cure diseases, and obtaining competitiveness in the world market. - One to three schools were considered as an appropriate number of schools with less than 80 students per class, Class size may be adjusted from existing schools (52.5% favored decrease in size) and (46.3% favored increase in size). - Educational and research facilities must be accopanied with schools of Oriental medicine as well as clinical training facilities, herbal pharmaceutical research centers, and fundamental medical centers. - Many favored 6 year curriculum as the most appropriate system and the school of Oriental medicine should be established within the university. Based on the information gathered in this survey, we may recognize the limitations of Oriental medicine schools at the private institutional level and support the establishment of Oriental medicine schools at th national university level. This establishment may play as a steeping stone for advancement in education, standardization of research and treatment, and commercialization of Oriental medicine of benefit the general public.
