Most of the convergence studies argue the reform of the current policy regime of broadcasting and telecommunications in Korea from two perspectives: 1) the media governance perspective and 2) the media industry perspective. The former emphasizes the need of integrity, consistency and efficiency of the regime in the convergence environment, while the latter focuses upon the growth and development of the media industry making the best of economic and industrial opportunities that are spawned by digital convergence. Although their arguments are logical and robust, they are lopsided in terms of legalism and myopic economism due to the linear perception of institutionalism, Bureaucratic administrative practices as well as ostentatious IT policies that have chronically plagued the policy regime in Korea cannot be resolved by simply assimilating distinct regulatory bodies and laws. Unless these two issues are properly addressed, the convergence of media policy institutions would end up a half-success or half-failure contrary to the exportations of existing studies.

The purpose of this study is to explore how North Korean woman defectors' memories of their past lives are represented in Korean television talk show, (Channel A, 2011~) and its social implications. In order to carry out this task, this study first discusses the emergence of the concept of 'memory' in its relations with 'collective memory', 'cultural memory' and 'history', and its social appropriation in media such as television. And, the ideological aspects of the recent trend of television talk show that deals with people's private memories were also discussed. The study used the method of structural narrative analysis. The findings are the following. First of all, North Korean woman defectors' memories in collide with the dominant public memories in South Korea. In any case, it has been found that the show tended to make North Korea and their defectors as exotic 'others' and thereby reinforce the existing public memory. After all, this study argues that the representation of the defectors' memories in the talk show only results in stressing the melodramatic narrative emotionally packaged with 'laughing' and 'crying' without any sincere consideration of them.

Legislation needs to be understood within a political, societal relationship among lawmaking bodies rather than by legal provision itself. In order to examine features and functions of communication in the process of legislation, this study conducted focus group interviews with experts as well as in-depth individual interviews. The result of this research as follows: First, the study found that although the domestic legislative process has been made by active interactions among lawmaking subjects, it was hard to conclude that this procedure is providing effective and productive legislative agenda because of chaotic communications made along the process. Second, the study found that national legislative process has been gradually moving, although restricted, to an open political space, the National Assembly, from a closed space, the executive branch. Third, the study found a remarkable feature including growing influence of experts groups and civic organizations in the legislative process. It is a significant change that legislative staff such as National Assembly aides, investigators, expert committeemen and deputy director generals played a role of "insiders," unnoticeably influencing the legislative process, and that civic organizations and NGOs, which have been excluded in the previous legislative processes, emerged as a new influencing circle in the process. Lastly, the study found that media organizations, in the process of developing agenda, had a strong impact on the National Assembly as a subject forming public issues and as a messenger of the legislative agenda while they played a limited role in affecting the government. This study discusses why communication in the domestic legislative process is important and what are some hindering and facilitating factors in the process.

This study explores the political parody, which has become an active art form in order to express Korean Internet users' political practices, especially, during the politically turbulent periods from the presidential election of 2003 to the recent candlelight vigil protest of 2008. This study investigates the rise and fall of a parody culture by online users from the mid-2000s, and also examines aesthetical aspects of parodic artworks relying on amateurism culminated in 2004. Specifically, the current study questions an aesthetical lack shown in 'appropriation', by which most of the online users simply produce imitations of original image. This study rather notes 'photomontage' as an aesthetic prototype, the political aesthetics made by John Heartfield, through which this study intends to observe how his aesthetical legacy of political art could be realized in the contemporary form of political parodies produced by online users. The present paper concludes that online users' political participations in producing critical works of art could allow us to negate the dichotomy between the elite and the mass, professional artists and amateur parodists, and a radical politics and the politics of style.

The effects of a simultaneous application of KCl and lime on the root uptake of $^{54}Mn,\;^{60}Co,\;^{85}Sr\;and\;^{137}Cs$ by rice, soybean, Chinese cabbage and radish were investigated through 2 years' greenhouse experiments. At their early growth stages, a mixed solution of the radionuclides was applied to the water or soil surfaces of the culture boxes filled with an acidic loamy-sandy soil for the upper 20cm and $83g/m^2$ of fertilizer KCl and $200g/m^2$ of slake lime were applied to the surfaces. Distribution of radioactivities among plant parts and change in uptake pattern with plant species were not, on the whole, significantly affected by the application. It reduced effectively soil-to-plant transfer factors of $^{85}Sr\;and\;^{137}Cs$ for rice, of all for Chinese cabbage and of $^{54}Mn,\;^{60}Co,\;and\;^{137}Cs$ for radish without their growth inhibition. In rice, $^{85}Sr$ showed the highest decrease $({\sim}60%)$ while, in Chinese cabbage and radish, $^{54}Mn$ did $({\sim}80%)$. The exprimental results can become valuable reference data to establish countermeasures against a radioactive contamination of farm-land during plant growth.

This study investigated the factors affecting the procedures of becoming a scientist. Interview was used as a research method for deep understanding of individual career choice procedures. Interviews for individual scientists were conducted for about 60 minutes in their offices and all the interviews were tape-recorded. A total of 34 scientists who received some representative science awards in Korea during 1990 - 2001 were sampled. They were all men. But the interview was conducted with 30 scientists. The investigation was based on the framework that was composed of the following four categories: personal ability, home environment, school environment, and sociocultural environment. And each category had several factors as follows: personal ability consisted of the meta-ability to figure out the aptitude and the self-ability and the achievement; home environment consisted of parents, brothers and sisters, relatives, and hobby; school environment consisted of teachers, friends, club activity; sociocultural environment consisted of event, mass media, social recognition and social prospect. From the analysis of the career choice procedure of the scientists it was appeared that the meta-ability for personal ability, the parental influence particularly by father for home environment, science teacher and professor for school environment, and social prospect for sociocultural environment were important. In conclusion, most of the scientists made an important decision for their future career when they were the 12th grade and 1st year in university, and they considered intrinsic factor such as self-interest and aptitude and extrinsic factor such as social prospect. However intrinsic factor related to science teacher and professor and extrinsic factor related to fathers' advice.

The growth of ark shell, Anadara broughtonii was compared between two areas, $Gad\v{o}gdo$ in Jinhae Bay and Namhae located in the southern coast of Korea from May 1986 to October 1987. The ark shells in Namhae grew from 1.38$\pm$0.32 em to 7.20$\pm$0.30 em in shell length, while those in $Gad\v{o}gdo$ grew from 1.38$\pm$0.32 em to 6,41$\pm$0.30 cm in 17 months. Shell height, shell breadth and total weigth of the ark shells in Namhae were also greater than those from $Gad\v{o}gdo$. Bottom quality of $Gad\v{o}gdo$ showed negative skewness, and that of Namhae was positive skewness. Negative skewness of $Gad\v{o}gdo$ seems to be caused by the effect of strong tidal current. This may indicate that Namhae is better area than $Gad\v{o}gdo$ for the culture of the ark shell.

The purpose of this paper is to highlight the importance of conflict management by local government by explaining a peculiar case of Namyangju city's construction project of landfill site for incineration remnants. Policy stage and internal dynamics of conflict between city and opposition group of local residents are used as major tools of case observation. From this analysis, this study finds that the conflict management effort of local government is critical to bring a success of a public policy. The local government needs to assess possible sources of conflict, and to prepare reasonable solutions through sincere communication with local residents. Also we need to reconsider the concept of administrative efficiency. Sometimes "slow" is better than "fast". Authoritative and hasty policy process may face unexpected obstacles, then consume more time to fulfill the policy goals. It means that the local government needs to spend more time for policy formulation. It also shows the importance of democratic process in reaching a public policy decision. In conclusion, this study confirms that the cooperative relationship between local government and residents, so-called governance, is the key to the success of public policy.

Tricholoma matsutake ectomycorrhizas are unique in their morphology: not bifurcated broom shaped roots with not easily wettable brilliant and profuse white hyphae. To understand these characteristics the ectomycorrhizas were investigated with electron microscopy. T. matsutake ectomycorrhiza have thin mantle and typical Hartig net development in the epidermis and cortex, but no fungal mantle on the root apex. There were no penetrating hyphae inside of the cells of either epidermis, cortex or stele. Inside of the walls of epidermis and cortex cells are lined with ca. $2{\mu}m$ hemispherical amyloplasts. The brilliant hyphal surface was covered with various fine amorphous granules. The hyphal cell wall was thin membrane less than $0.3{\mu}m$ thick. There is no clamp connection on the hyphae. This thin membraneous cell wall with high elasticity can be related to survival strategy of the species without plasmolysis under frequent soil water stress environment. And the coarse hyphal surface with some water repellency can control sudden inrush of water of the hyphae with an extremely low osmotic potential. It is concluded that no mantle on the tip can induce mycorrhizas not bifurcated and that finely coarse surface of T. matsutake hyphae can make the hyphae brilliantly white but less wetted.
