  • The experiment has investigated the effects of blending rate of waste rockwool in nursery media on growth of Marygold 'Yellow boy' plug seedlings. A commercial plug medium containing 10% zeolite, 10% vermiculite, 5% perlite, 10% peatmoss and 65% cocopeat was used as the control, and the other media compounded with 10% of zeolite, vermiculite, perlite and peatmoss and 10, 30, and 50% of waste rock-wool. There was not significant difference in germination rate ot Marygold between treatments. Plant height, number of leaves, stem diameter and leaf area were higher in commercial plug medium and compound nursery media containing 50% of waste rockwool than 30 or 10% of waste rockwool. Fresh weight and dry weight of shoot and root increased in the treatment of commercial plug medium and the medium of 50% waste rockwool than 10 and 30% of waste rockwool. These results suggested the possibility of utilization of waste rockwool for medium components of plug seedlings.

  • This paper focuses on the social implication of new media art, which has evolved with the advance of technology. To understand the notion of human-computer interactivity in media art, it examines the meaning of "cybernetics" theory invented by Norbert Wiener just after WWII, who provided "control and communication" as central components of his theory of messages. It goes on to investigate the application of cybernetics theory onto art since the 1960s, to which Roy Ascott made a significant contribution by developing telematic art, utilizing the network of telecommunication. This paper underlines the significance of the relationship between human and machine, art and technology in transforming the work of art as a site of communication and experience. The interactivity in new media art transforms the viewer into the user of the work, who is now provided free will to make decisions on his or her action with the work. The artist is no longer a godlike figure who determines the meaning of the work, yet becomes another user of his or her own work, with which to interact. This paper believes that the interaction between man and machine, art and technology can lead to various ways of interaction between humans, thereby restoring a sense of community while liberating humans from conventional limitations on their creativity. This paper considers the development of new media art more than a mere invention of new aesthetic styles employing advanced technology. Rather, new media art provides a critical shift in subverting the modernist autonomy that advocates the medium specificity. New media art envisions a new art, which would embrace impurity into art, allowing the coexistence of autonomy and heteronomy, embracing a technological other, thereby expanding human relations. By enabling the birth of the user in experiencing the work, interactive new media art produces an open arena, in which the user can create the work while communicating with the work and other users. The user now has freedom to visit the work, to take a journey on his or her own, and to make decisions on what to choose and what to do with the work. This paper contends that there is a significant parallel between new media artists' interest in creating new experiences of the art and Jacques Ranci$\grave{e}$re's concept of the aesthetic regime of art. In his argument for eliminating hierarchy in art and for embracing impurity, Ranci$\grave{e}$re provides a vision for art, which is related to life and ultimately reshapes life. Ranci$\grave{e}$re's critique of both formalist modernism and Jean-Francois Lyotard's postmodern view underlines the social implication of new media art practices, which seek to form "the common of a community."

  • The purpose of this study is to identify components of CEO image and to examine predictors to affect company's market value. To explore the social construction of the CEO Image depicted in the popular business newspaper, the Wall Street Journal and daily newspaper of Korea, was analyzed. Then, the reconstructed image of the CEO was compared with the firm's stock price change to see their relationship, if any. This paper focused on the case of Carly Fiorina as previous chief of Hewlett-Packard, who was the Fortune's ranking of the 50 most powerful women in business is presented. The period for the analysis was five years and eight months from her inauguration(July, 1999) to the release(February, 2005). The results, four predictors such as nature, management ability, leadership style, appearance character had statistically significant relationship with both company's market value and the image of CEO. In addition to revealed that media coverage of Carly Filoina was commensurate with the financial performance, particularly stock price change of the Hewlett-Packard. In general, the best image of the CEO is highly transcends to the image of the company as well. Therefore it is need to manage effectively components of CEO image to enhance brand image and its brand value, which are further expected to enhance company's market value.

  • Objectives: A content analysis was conducted to examine whether the current school textbooks providing smoking information are effective or not. Methods: The authors reviewed 111 qualified textbooks using elementary through high schools during 2006-2007 academic year in Korea. Educational components were coded with an analysis tool developed through the present research. Result: Tobacco education components were narrowly focused on long-term physiological consequences of tobacco use, addictiveness, and harmful ingredients and they were repetitively shown in the textbooks. Negative health consequences such as lung cancer were emphasized 10 times among 12 smoking-related textbooks. Educational messages or contents are mainly based on medical knowledge (72%) rather than psycho-social components. The US school-based smoking prevention programs, however, employ psycho-social approach with cognitive and life-skill components and they contain only 7-17% of smoking-related medical knowledge. In order to increase psycho-social smoking prevention components in Korean textbooks, the present study identified social subjects of textbooks (and relating core sessions) for elementary, middle, and high school. It also provided guidelines for school instructors to use. Conclusion: Adolescent smoking behavior is not caused by the deficit of health information, but mostly by social influences including media and peer pressure. School textbooks proving smoking information need to increase psycho-social context. One of the most effective ways as a psycho-social smoking prevention program is to use social subjects (or curriculum) of textbooks such as social studies, ethics, social cultures, social environment, and home management.

  • This paper presents a study of soil-structure interaction problems using infinite elements. The infinite elements are formulated for homogeneous and layered soil media, based on approximate expressions for three components of propagating waves, namely Rayleigh, compressive and shear waves. The integration scheme which was proposed for problems with single wave component by Zienkiewicz is expanded to the multi-wave problem. Verifications are carried out on rigid circular footings which are placed on and embedded in elastic half space. Numerical analysis is performed for a containment structure of a nuclear power plant subjected seismic excitation.

  • A sequence of functions are examined for the gradient-index AR thin film between two dielectric media and are used as the starting profiles in optimization to improve AR performance. Sinusoidal functions were quite efficient to use as components of the index change in the optimization. It is shown that there exist a number of gradient-index profiles which exhibit excellent AR-performance after control of the gradient-index profiles.
