  • Polycrystalline silicon films were deposited using hot wire CVD (HWCVD). The deposition of silicon thin films was approached by the theory of charged clusters (TCC). The TCC states that thin films grow by self-assembly of charged clusters or nanoparticles that have nucleated in the gas phase during the normal thin film process. Negatively charged clusters of a few nanometer in size were captured on a transmission electron microscopy (TEM) grid and observed by TEM. The negatively charged clusters are believed to have been generated by ion-induced nucleation on negative ions, which are produced by negative surface ionization on a tungsten hot wire. The electric current on the substrate carried by the negatively charged clusters during deposition was measured to be approximately $-2{\mu}A/cm^2$. Silicon thin films were deposited at different $SiH_4$ and $H_2$ gas mixtures and filament temperatures. The crystalline volume fraction, grain size and the growth rate of the films were measured by Raman spectroscopy, X-ray diffraction and scanning electron microscopy. The deposit ion behavior of the si1icon thin films was related to properties of the charged clusters, which were in turn controlled by the process conditions. In order to verify the effect of the charged clusters on the growth behavior, three different electric biases of -200 V, 0 V and +25 V were applied to the substrate during the process, The deposition rate at an applied bias of +25 V was greater than that at 0 V and -200 V, which means that the si1icon film deposition was the result of the deposit ion of charged clusters generated in the gas phase. The working pressures had a large effect on the growth rate dependency on the bias appled to the substrate, which indicates that pressure affects the charging ratio of neutral to negatively charged clusters. These results suggest that polycrystalline silicon thin films with high crystalline volume fraction and large grain size can be produced by control1ing the behavior of the charged clusters generated in the gas phase of a normal HWCVD reactor.

  • A phenomenon in the unplanned urban sprawl of Cheong-ju city has to be rest-rained from disposing and to develop, though progress in urbanization inevitably decreases rural area. So, this thesis aims at reviewing, revising and guiding toward the more effective land use planning practice and zoning mechanism and system of Cheong-ju city. I proposed that land use planning should be had several factors and thereupon that Korean zoning mechanism and system including Building Code should be amended because of inducing human activities in buildings and facilities not to demarcate and plan every one of them. First, the factors of urban planning are a rather diversified approach to it than a unified, supplementation of the applicable difference in time between preparing and appling it, a solid controlling system, a micro and macro planning theory and giving serious consideration for the inertia from the existing land use. Second, the applicable amendments for our zoning mechanism including Eluding Code are as follows; a need of reorganization for Zoning Ordinance appricated to different regulation concerning a scale and peculiarity of a oily, a decision of the different earmarked confinement in area to different zone ana from Zoning Ordinance in City Planning Law, a demarcated facilities and the more detailed land use concerning human activies than the exsisting and entrusting decision on the ways and processes of it to every rural city planning committee, a settlement of zone ana area considering for block-unit and Planned Unit Development(P. U. D.), and a need of security jurisprudence in order to solve the zoning regulation rather in City Planning Law than in Building Code that our zoning regulation and controlling system are depended on. According to these applicable amendments to Cheong-ju city, I proposed the conceptions of Cheong-ju city land use planning are as follows; a reinforcement with one cored pattern of urban land use, a selection of gradual urban sprawl by way of city development and renewal, a strengthening accessibility to the core of the city with Plurizing the system of arterial roads, a choice of priority to conservation at the core of tile city and security of open spaces and parking area at the area of the city, a harmonization between development and conservation at the inner ring area that is situated between the core and periphery reserved area in order to develop in the future, a buffered open space situated at the congested area with heterogenous functions, and a completion of urban open space system. The proposal made here so far is for the hope of the better structure of Cheong-ju city that should be granted to the peculiarity developed with educational, cultural, conservative and self-sufficient city functions.

  • The oceans are the largest body of water geographical unit in the earth. In accordance with the general said of the international law, countries on the international law must have four elements: 1) settled residents; 2) determined territory; 3) a certain degree of government organizations; 4) the sovereignty. The country's basic rights are: 1) the right to independence; 2) the right to equal; 3) the right to jurisdiction; 4) the right to self-protection. UNCLOS as the only one of the "Constitution of the Earth" on the earth, the implementation of its entry into force make about 1/3 of the world's oceans should be assigned to the coastal states, in the use and management of ocean gave the coastal states the center jurisdiction, the coastal states' jurisdiction sphere had been expanded, the power comparison among all countries in the world had new changes. The ocean territory, like the land territory, is the most major material condition of a country. The ocean's strategic status is extremely important, is the important stage of the international political, economic and military struggle, there are many disputes about the rights and interests, resources and the development and utilization on the oceans. To resolve these disputes is bound to depend on a strong comprehensive national strength, including politics, economy, science and technology, as well as the powerful marine force, in which maritime police plays an important role.

  • This study analyzed a unique method of problem-handling, attitudes, and specific interest propensity in the career path of the type with inconsistency in the relative distance between personality type in Holland's hexagonal model. In-depth interviews and theme analysis with six clients who showed inconsistent personality type were conducted. These six were selected from 87 participants that had received training at the Korea Vocational Counselling Association, Korea Training Institute for Self-Sufficiency and Korea Employment Agency for the Disabled. From the analysis, the six clients with inconsistent 3 Codes showed four characteristics - more than three career experience, various interest pursuits, career involvement, and career identity. They were affected in their vocational behavior by their own Holland 3 Codes and showed vocational behavior very different from Holland's theory of person-environment fit approach. They showed positive, ambivalent and chaotic types on career identity. Furthermore, Conventional(C)-Investigative(I)-Social(S) 3 Codes type and Artistic(A)-Enterprising(E)-Realistic(R) 3 Codes type in the same inconsistent personality type showed different vocational behaviors in career path development, which relates to the meaning of Holland's 3 Codes. The significance of this research lies in its provision of various points for improving career counselling.

  • "When it comes to art, nationalism is a goodticket to ride with", says the title of a report in the Indian Express (Mumbai, 29 Oct 2000). The newspaper report goes on to say that since Indian art was kept "ethnic" by colonialism, national liberation meant opening up to the world on India's own terms. Advocacy, at the tail end of the 20th century, would contrast dramatically with the call by Rabindranath Tagore, the founder of the academy at Santiniketan in 1901, to guard against the fetish of nationalism. "The colourless vagueness of cosmopolitanism," Tagore pronounced, "nor thefierce self-idolatry of nation-worship, is the goal of human history" (Nationalism, 1917). This contrast is significant on two counts. First is the positive aspect of "nation" as a frame in art production or circulation, at the current point of globalization when massive expansion of cultural consumers may be realized through prevailing communication networks and technology. The organization of the information market, most vividly demonstrated through the recent FIFA World Cup when one out of every five living human beings on earth watched the finals, is predicated on nations as categories. An extension of the Indian Express argument would be that tagging of artworks along the category of nation would help ensure greatest reception, and would in turn open up the reified category of "art," so as to consider new impetus from aesthetic traditions from all parts of the world many of which hereto fore regarded as "ethnic," so as to liberate art from any hegemony of "international standards." Secondly, the critique of nationalism points to a transnational civic sphere, be it Tagore's notion of people-not-nation, or the much mo re recent "transnational constellation" of Jurgen Habermas (2001), a vision for the European Union w here civil sphere beyond confines of nation opens up new possibilities, and may serve as a model for a liberated sphere on global scale. There are other levels of collectivity which art may address, for instance the Indonesian example of local communities headed by Ketua Rukun Tetangga, the neighbourhood headmen, in which community matters of culture and the arts are organically woven into the communal fabric. Art and collectivity at the national-transnational level yield a contrasting situation of, on the idealized end, the dual inputs of local culture and tradition through "nation" as necessary frame, and the concurrent development of a transnational, culturally and aesthetically vibrant civic sphere that will ensure a cosmopolitanism that is not a "colourless vagueness." In art historical studies, this is seen, for instance, in the recent discussion on "cosmopolitan modernisms." Conversely, we may see a dual tyranny of a nationalism that is a closure (sometimes stated as "ethno-nationalism" which is disputable), and an internationalism that is evolved through restrictive understanding of historical development within privileged expressions. In art historical terms, where there is a lack of investigation into the reality of multiple modernisms, the possibility of a democratic cosmopolitanism in art is severely curtailed. The advocacy of a liberal cosmopolitanism without a democratic foundation returns art to dominance of historical privileged category. A local community with lack of transnational inputs may sometimes place emphasis on neo-traditionalism which is also a double edged sword, as re kindling with traditions is both liberating and restrictive, which in turn interplays with the push and pull of the collective matrix.

  • This thesis examines contemporary Chinese painting after the Cultural Revolution(1966~76), focusing upon so-called "Chinese Pop art", which I termed as "Socialist Pop art". I considered the art of this period within the broader context of social changes especially after the Tienanmen incident of 1989. After the Cultural Revolution during which idolization of Chairman Mao was at its peak, one of the major changes in communist China was that an anti-Mao wave was generated in almost every social class. For example, novels that revealed the hardships during the Cultural Revolution were published. Posters that openly criticized the Maoism were also produced and displayed on the walls, and demand for democracy spurred widespread activist movements among young generations. These broad social changes were also reflected in art. A variety of art movements were introduced from the West to China, and after a period of experimentation with the new imported styles, artists began to apply the new artistic idiom to their works in order to visualize their own social and political realities they lived in. It was a shift from earlier Socialist Realism to a new expression either directly or indirectly, "Socialist Pop", an amalgam of Socialist Realism and Pop art tradition. After the 1989 crackdown of Tienanmen Square protest, when communist government quelled with brutal measures the students, workers, and ordinary people who rose for democracy, greater urge to protest the Deng Xiaoping regime emerged. This time coincided with the gradual emergence of art using Pop art vocabulary to satirize the social reality, the Socialist Pop art, along with many other art forms all with avant-garde spirit. One of the most frequent subjects of Chinese Pop art was visual images of Chairman Mao and his Cultural Revolution, and new China that was saturated with capitalism, which tainted the Chinese way of life with a Western way of consumerism and commercialism. The reason for the popularity of Mao's image was spurred by the "Mao Craze" in the early 1990's. People suddenly began to fall in a kind of nostalgia for the past, and once again, Mao Zedong was idolized as an entity who can heal the problems of modern China who had been marching towards their ultimate destination, the economic development. But this time Chairman Mao was no more an idol but just a popular, commercial product. He is no more an object of worship of almost religious nature but he has become an iconography symbolizing the complex nature of present Chinese society. During this process of depicting the social reality, Chinese artists are making the authority and sanctity of Maoism ineffective. Dealing with this new trend of contemporary Chinese art in view of "Socialist Pop art" two manners of re-creating Pop art can be illustrated: one that incorporates the propaganda posters of the Cultural Revolution; the other borrows from Chinese traditional popular imagery or mass media, such as photos taken during Mao era. What is worth mentioning is that these posters and photos of the Cultural Revolution can be identified as 'popular' media, as they were directed to educate the popular mass, thus combination of this ingenuous pop media with Western Pop art can be fully justified as a genre unique to China. Through this genre, we can discover a new chapter of the Chinese contemporary painting and its society, as their Pop art can be considered as self-portraits true to their present appearances.

  • The study investigated information about the effects of message framing on colorectal cancer(CRC) screening related health beliefs and compliance with the CRC screening test within the theoretical framework of the prospect theory and the Health belief model (HBM). This study was using a non-randomized controlled quasi-experimental design. One hundred and sixty-four in the industrial workers who were currently nonadherent to guidelines for receiving screening were assigned to one of three experimental conditions: (a) gain-framed message, (b) loss-framed message, and (c) general-framed message. CRC screening-related health beliefs was self-reported after the intervention. And the immunoassay Fecal Occult Blood Test (iFOBT) kit was collected at 1 week. The research finding were analyzed by $x^2$ test and one-way ANOVA using SPSS 21.0. The loss-framed message group had higher perceived susceptibility, severity and benefit than the gain-framed message and general message. The participation rate for the immunoassay Fecal Occult Blood Test(iFOBT) was highest in the loss-framed message group. The loss framed messages more effective to enhance screening behavior. The present results provide a theoretical basis for developing educational guidelines for CRC testing and could be used for performing comprehensive approach by predicting and suggesting the practical effects according to message type in advance.

  • The OSGi service platform has several characteristics as in the followings. First, the service is deployed in the form of self-installable component called service bundle. Second, the service is dynamic according to its life-cycle and has interactions with other services. Third, the system resources of a home gateway are restricted. Due to these characteristics of a home gateway, there are a lot of rooms for malicious services can be Installed, and further, the nature of service can be changed. It is possible for those service bundles to influence badly on service gateways and users. However, there is no service bundle authentication mechanism considering those characteristics for the home gateway In this paper, we propose a service bundle authentication mechanism considering those characteristics for the home gateway environment. We design the mechanism for sharing a key which transports a service bundle safely in bootstrapping step that recognize and initialize equipments. And we propose the service bundle authentication mechanism based on MAC that use a shared secret created in bootstrapping step. Also we verify the safety of key sharing mechanism and service bundle authentication mechanism using a BAN Logic. This service bundle authentication mechanism Is more efficient than PKI-based service bundle authentication mechanism or RSH protocol in the service platform which has restricted resources such as storage spaces and operations.

  • The purpose of this study is to consider ontology theory and get to forge design and implementation of ontology-based access system which is support to the nutrition and food guide tower of Home Economics textbooks in middle school in order to offer the way of effective learning performance. It offers a model by establishing a nutrition and food guide tower access system based on Protege-2000 framework. This system is on the basis of XML, and it makes possible to work with semantic web, a next generation internet technology, and provides a meaning structure that can be shared in the field of nutrition in order to build up the fundament of knowledge an information system for the mutual operations. A learner can systemize the knowledge through a self-information access and an instructor can also check out the degree of learner's learning-accomplishment and interests, directly putting the access system into the teaching and learning process. In addition, it is supposed that the learner can maintain a balance and healthy life by internalizing his or her knowledge throughout ontology not only in a teaching and learning process but also in a daily life.

  • It is an aim of this study to analyze a relation between modern medicine advertisements and body. Recently the academic world has discussed how comes it that the modernity had been formed. This trend is remarkable in the field of the history of everyday life. Because everyday life is connected with people's vivid experience. Especially in modern advertising it is in existence such as popular culture, consumer culture, sexuality, family, food, clothing and housing, disease. Since modern times the body has been reorganized into a new shape. Namely the premodern body that had been regulated by a status system is changed into modern body that have to form itself after the customs and values. We analyzed medicine advertisements in the early modern times and hoped to explain how modern people had understood their body. We applied Foucault's theory of discourse as a methodology. As a result of research, we came to the conclusion that there were several rules in the texts of medicine advertisements, which had formed a modern subject of pain. There was a disciplinary power such as a internalization of clinical eyes, self-watch in medicine advertisements. These advertisements contributed to the formation of subject of pain and related to the state power.
