The 21st century is the era of the center of the Originality(of thought). It also emphasizes creativity and creative education policy based on the new changes are dreaming. Creative education through art grasp the essence of things, seek express oneself, and brings cognitive ability. An educatee promote the development of creativity and insight on things other than the existing. New thinking will gain the ability to make rational faculty of the mind and principle. Creative education implement in homes, schools, communities, public agencies, private organizations, and running through the creative environment, but the number of trainees are exposed to extremely rare. The creative practice book in charge of creative education of the dissemination insufficient of research and development in reality. The creative practice book requires a new approach. It can be seen easily accessible environment where everyone should be able to provide for nationwide. In this respect, the creative practice book through art to begin consideration, is studied a whole spectrum, and be published in variety of practice books.

Measurements of heat release are very important for controling combustion instabilities, which are closely connected with combustion instabilities. $OH^{\ast}$ images were acquired through a ICCD in this study, which were in use as indicating index of the reacting region, global and local heat release rate in the lean premixed combustion. The objectives of this study are to see the effect of equivalence ratio on global heat release rate and local Rayleigh index distribution. The local Rayleigh index distribution was acquired by information from central section of flame. This information was from the line-of-sight images which were inverted by the Abel de-convolution. In each condition, the mean value of heat release increased exponentially with equivalence for a periodic time. Local Rayleigh index distribution cleary showed the region of amplifying or damping the combustion instability as the equivalence ratio increased. This could provide an insight on the region of combustion instability and the structure of flames on the equivalence ratio.

For Bauhaus, the vaious typography experiments developed around the printing workshops, and it was only in the later Weimar Period that L. Moooly-Nagy, who came to be in charge of the rxinting workshops, approached it from the functional way of thinking and demanded print type reforms Using this as the basis, a new form of typograph called "typophoto" was developed by combining images and characters together using photography techniques and Bauhaus Unification Chaacter producyion. Harbert Bayer, striving at molds based on the ideologies of L. Moody-Nagy, prepared the framework for modern informational advertisements by producing a variety of advertisements based on several law of psychology and physiology. Bayer's successor, Joost Schmidt focused on lettering based on functionalism and typographic training and practice, while pioneering in the new area of display design wiwh efficient usage of space for exhibitions a1d dsplays. Thus, despite being carried doWl by the same leader in the sane era, the series of typographic experiments undertaken by the artists Bauhaus present guidelines to the direction modern visual communication must take through creativity and insight into the upcoming future that is not contained within the boundaries of traditions and customs.and customs.

The ecological crisis today can be seen as a result of modernity which has been developed on the Cartesian dualism of subject/object, and of human being/nature, and thereby has huts objectified and subjugated nature through science and technology New environmental ethics hence should be developed urgently against modernity and to overcome the present ecological crisis. This paper aims to consider some implications for ecology and environmental ethics in the post-structurists'arguments struggling against modernity to formulate new frameworks of discourse and politics, and to examine a possibility to theorize environmental justice on the basis of postmodem ecology. For this purpose, this paper first looks on ecological arguments and implications for environmental ethics in post-structuralism, then tries to gain prominent ecological insights, focusing on ethology and 'rhizomatic naturalism'in the philosophy of Deleuze, and finally interprets both bioregionalism as a theory of 'difference' from postmodern point of view and Deleuze's ecology in terms of symbiosis and difference, in order to conceptualize environmental justice.

Ongoing advances in wireless broadband technologies can affect all of industrial society. As new wireless broadband technologies emerge, they will improve competition between established industries and their current services and produce new industries and new converged services. This paper analyzes the trend of next-generation wireless broadband and suggests ways of activating the industry further. To this end, we analyze the trend for previous wireless broadband industries and find out three influential factors (content, wireless network technology, and service) that will produce the continued growth of wireless broadband. Using these three factors, we propose a network technology-driven growth model. Based on that model, we offer activation plans for next-generation wireless broadband industries. This study thus provides an insightful perspective for next-generation wireless broadband industries by establishing additional useful guidelines for developing wireless broadband industries in the future.

Many organizations experience that the value they gained from IT (information technology) investment is lower than they expected prior to the actual implementation of a system - the value gap between expected value and realized value from IT. Research on the barriers to the expectation and realization is of high importance both in practice and in IS research. This study analyzed such barriers observed in three companies that have adopted such IT systems as Enterprise Resource Planning (ERP), Supply Chain Management (SCM), and Customer Relationship Management (CRM) systems each. From analyses of the three companies we specifically identified eight types of barriers: barriers related to industry, organization, knowledge, resource, usage, competence, product, and safety. Common barriers among the three cases were classified into six types, e.g. lack of strategic mind-set, improper organizational structure, lack of human resource, etc. We expect that the results help managers in IS investment to minimize the valuation gap and maximize realized values.
