A total of 1,354 samples was collected from bovine and porcine carcass from January 2005 to December 2006 in a slaughter house. Twenty five strains(1.8%) of Listeria monocytogenes were isolated from 1,354 samples using selective media. Ten(1.4%) L monocytogenes were isolated from the 677 of bovine carcasses, and 15(2.2%) were isolated from the 677 of porcine carcasses. Among 15 L mono-cytogenes from porcine, 11 siolates were serovars 1/2c, followed by 1/2b (3 strains, 20.0%) and 1/2a(1 strain) Out of 10 bovine samples, positive cases in 1/2a were 9 strains (90.0%), 1/2b were 1 strains(10.0%). PCR primers were selected to amplify a 520-base pair(bp) DNA fragment from the listeolysin O gene (hlyA) of L mono-cytogenes. A 520-bp product was detected in PCR with DNA from L monocytogenes, but not from the other Listeria species tested. A total of 25 L monocytogenes strains were analysed by PFGE after digestion with Apa I. PFGE analysis of genomic DNA showed the $14{\sim}18$ fragments ranging in size from 30 to 550 kb, resulting in 14 patterns.

Objectives: The aim of this study is to investigate microbial contamination in the school food service environment for the assessment of microbial food safety. Methods: We collected both swab samples from tables and desks and airborne bacterial samples from an elementary school (School A) and a high school (School B). Heterotrophic plate count, total coliform, Staphylococcus aureus, and Bacillus cereus were measured with selective media to quantify microbial concentration. PCR assay targeting 16S rRNA genes was performed to identify the strains of S. aureus and B. cereus isolated. In addition, we made a food service checklist for the locations to evaluate the food service environment. A Wilcoxon test was employed to examine the differences in microbial concentration between before lunchtime and afterwards. Results: Heterotrophic plate counts showed higher levels after-lunch compared to before-lunch at School B. However, levels of S. aureus were higher in the after-lunch period (p<0.05) in both classrooms and in the cafeteria in School A. B. cereus was only sparsely detected in School B. Several samples from food dining carts were found to be contaminated with bacteria, and facilities associated with food delivery were found to be vulnerable to bacterial contamination. Although microbial concentrations in the air showed little difference between before- and after-lunchtime in the cafeteria in School A, those in classrooms were greater after-lunchtime at both schools. Conclusion: Our results suggested that the microbial safety in schools after lunchtime of concern. Necessary preventive measures such as hygiene education for students and food handlers should be required to minimize microbial contamination during food service processes in schools.

Media scholars take a lion stake in power circle. Not only do they take a part in media policies but seize prestigious positions like board members in Korea Communication Commission(KCC). Unfortunately, though, little has been known about who they are, what qualifications they have, and whether they meet public interests. This paper attempts to unveil the mechanism of those politicized intellectuals who are specialized on the media. Two categories divided into 'representative' and 'expertise' are employed for this purpose. On the one hand, the representative means the degree of committment into such public services as participation in conferences or non-profit organizations. On the other hand, the number of research articles, books and projects belong to the expertise. Evaluation levels consist of 'excellence, good and average' were allocated to those scholars who are(were) in 'Power Hole,' where decision makings come into being. Some interesting observations were made though this study. First of all, such criteria as representative and expertise vaguely suggested by the laws were hardly fit into those intellectuals, Rarely did they commit into public service let alone showing vigilance in academic activities. Secondly, both ideological loyalty and political activities in line with the government had much to do with taking such positions. Thirdly, not surprisingly, it showed that to graduate from Seoul National University and have Ph.D. degree from U.S.A. was one of the most essential factors. In final, most of them were very good at taking advantage of the press in way of boosting their publicity. To attend at policy making processes either in form of board members or advisers is inevitable for media experts. However, as shown in this study, such qualification of public service and academic eagerness shouldn't be underestimated. Academic integrity not selling intelligence solely for private interests needs to be protected as well. The authors hope this study to provide a valuable opportunity to establish a kind of ethical standards in participating into politics.

This discussion is a study that proposes to introduce a strategy to positively interpret the narrative meaning in media language based on a generalized cognitive environment in order to activate correct media literacy in the era of cultural convergence. have. In particular, by using advertising content that has the most reinforced creativity related to cultural interpretation, it was induced to grasp the informational manifestation of that era and to reproduce meaning interpretation with relevance. In addition, it attempted to utilize an argumentative writing strategy in the process of reproducing Korean language learners' writing, which was capable of cognitive interpretation. The intention of the public service advertisement content developer always expects a positive effect in the social and cultural aspect, and the learner dreams of reflection and a correct future through the effect. The research on activating media literacy in the era of cultural convergence, which I intended, has not yet been much discussed. We hope that the proposed discussion of this study will be actively utilized in mass media language education of the contents of textbooks for Korean language learners, and we are sorry for the part that does not contain quantitative analysis contents, and we expect the results in subsequent thesis.

In this study VOD usage patterns(VOD use and paid amount) of IPTV users were investigated reflecting the level of media use characteristics such as TV viewing time, star preference, and genre preference. Also the impact of media using characteristics and the evaluation of guide channel on the intention to use VOD was analyzed. The web survey was conducted against the respondents who have used VOD and guide channel. The results are as follows. Among the media usage characteristics, star preference has the impact on the VOD use, while genre preference has relation to the willingness to pay for VOD. Secondly, the intention to view the guide channel, entertainment of the channel, and the users' genre preference have significant impacts on the intention to use VOD. Therefore, it is necessary to raise the viewing rate of guide channel by providing the customized promotion strategy and diverse events based on the analysis of VOD usage.

This paper deals with the longitudinal study on the supply & demand-side diversity of digital media service. The purpose of this study is to measure the diversity of contents supply and demand-side of digital media platform providers by longitudinal data and discuss the implication. In the approval and re-authorization of pay-TV broadcasters, there were attempts to measure diversity indicators as items to evaluate the publicness and public interest of broadcasting, but they are mainly limited to the method of measuring diversity in the short-term supply side. Thus researcher wants to confirm the evaluation of two aspects through this study. First, researcher proposes a demand-side measurement methodology that utilizes actual audience data from users, and second, a longitudinal evaluation methodology that evaluates long-term trends of diversity change. Researcher has secured the actual supply and demand data of the platform player and confirmed trends of longitudinal diversification indexing for 50 months from 2012 to 2017. Through this research, researcher expects that the supply and demand-side and the longitudinal diversity evaluation will be utilized in a balanced way of publicness and public interest evaluation of broadcasting.

Social media, also known as the 'revolution of communication', has become a major means of communication and service in contemporary society. Unlike existing media, the advantage of being able to deliver interactive information is already beyond the level of use between individuals and government efforts to use it. In fact, local governments in Korea operate one or more social media services for various purposes, which promotes policies of local governments or provides prompt information to local residents. These social media records are based on public business and should be managed as records. However, the legal basis for managing records of social media in the area of public records management is currently small, and each local government does not recognize the need for records management. Social media operate by local governments are not only of different types but also difficult to manage as standardized guidelines. Nevertheless, minimal guidance is needed to manage and preserve social media records. The purpose of this study is to draw out the least common elements in the preparation of guidelines for social media record management. For this purpose, the guidelines and policies established by advanced countries that already systematically manage social media were analyzed and the items and characteristics were derived. In addition, the guidelines were checked for application by comparing actual social media records with social media archives. This study is meaningful in that it proposed components that should be included in the development of guidelines for the management of social media records in local governments through the actual status of social media archive operations.

I conducted this study, trying to improve the methods of Sung-Nam city local tax bills, which was based on my previous study where I suggested methods into developing redesign of tax bills. Local tax bills are labeled to be very intricate and puzzling experience to tax payers. To resolve this issue, several local governments have redesigned their tax bills for citizens; however, it was not effective. Therefore I apply the methods to protect their privacy on tax bills and provide checks on their pay bills. Also I design to distinguish between different taxes and change into a better layout for their legibility and better understanding on tax bills. From my previous study, I utilized suggestions into Sung-Nam local tax bills which changed flaws into improvements and easier understanding of the tax payers. I believe the improvements in Sung Nam local tax bills will pursue the public interest of the community through public service design innovations.

Although the use of social media by doctors raises important issues concerning medical professionalism, the relevant professional bodies in South Korea have failed to issue clear guidelines on social media usage. The Korean Medical Association's newly revised ethics guidelines do require members to maintain dignity while using social media, but the idea of "maintaining dignity" is far from clear, and its premodern connotation prevents it from being reliably used in professional codes of conduct. The authors of this article examine the concept of maintaining dignity and conclude that once it is clarified and redefined it can and should be used as a viable ethical standard in a variety of contexts, including the use of social media. Social media's unpredictability and uncontrollability, and the blurred distinction between professional/public and personal/private can be a threat to medical professionalism. In order to deal with this threat, the concept of dignity is important. We present three examples in which the dignity of medical professionals is undermined and explain why these jeopardize public trust. We conclude that in order to maintain public trust the Korean Medical Association should provide more detailed guidelines on the use of social media by its members.

D-CATV VOD service provides various contents such as drama and movie with high quality regardless of time and place. As the usage time of the VOD service increases, the viewing time of real-time terrestrial broadcasting is shortened. As the demand for VOD service is high and the number of digital users is increasing, the VOD market is rapidly growing. Therefore this study investigates the age and gender analysis of digital cable TV users and analyzed the usage patterns and audience cases of users. VOD service has been shown to be used by many users for the first time through remote control and free coupons. Non-users of VOD service did not use it because of charge and did not feel the necessity, but some non-users did not recognize the free VOD service.
