The need for and components of a contemporary community pharmacy externship for pharmacy students have not been clearly identified in Korea. Mail survey was performed among 20 college of pharmacy deans and 800 community pharmacists to analyze the current status and develop a consensus regarding major focus area and criteria of community pharmacy externship to be implemented under the separation of dispensary from medical practice in year 2000. Mail survey yielded $80\%\;and\;23.5\%$ response rate for pharmacy school deans and community pharmacists, respectively. Of the 16 pharmacy schools that responded 14 said they have externship program in hospital pharmacy, and only 8 pharmacy schools responded of having externship program for community pharmacy. However, these community pharmacy programs lacked criteria and standard guideline for the externship. The results of survey revealed that community pharmacy externship program for students should be organized and directed toward developing expert knowledge and skills in pharmacy practice activities, clinical services, communications, pharmacy management, and professionalism. Pharmacy practice components should include competencies and skills in computer application, prescription processing, dispensing, pharmaceutical compounding, Narcotics Control Law application, maintenance and provision of drug information, and laws and regulations. Clinical service components should include the ability to identify patient's drug-related problems, provide long-term patient care and appreciate drug therapy services. Communication skills should be taught to effectively express his/her professional opinion, deduce the needs of others, utilize appropriate techniques and media to communicate ideas and conduct a patient interview and to obtain patient drug history. Pharmacy management skills should be taught to be efficient in medical insurance and drug control process. It was found that professionalism, morality, pharmacy practice experience, ability to provide clinical services, collect and provide drug information and regality are important criteria of preceptors. Externship sites should possess the ability to stock various drugs, access and provide diverse pharmacy services and should have private patient counseling area. Most pharmacists agreed that top 200 drugs' generic and brand name, indications, dosage, side effects, and contraindication should be instructed during the externship. It was also found that student and preceptor should be evaluated for their performances during the externship. This information will be incorporated into teaming objectives for students and to develop Academic Extemship Program Guidelines.

This study examined the perceptions of and attitude towards mixed-race and investigated the factors affecting them and their influence on discriminative behavior. For the study, a survey was conducted with residents residing in Seoul and its suburb. The results showed that the perceptions of and attitudes towards mixed-race, generally, were not so negative and positive in all three types of mixed-race, Caucasian-korean, Asian-korean, and African-korean. In addition, the perceptions of and attitudes toward mixed-race were partly different by the type of mixed race. That is, there were more positive perceptions of and more favorable attitudes towards the Caucasian-korean in Asian-korean and African-korean, and there were less positive perceptions of and less favorable attitudes towards Asian-korean than in African-korean. With regard to the factors affecting the perceptions and attitudes, racism was a factor affecting commonly the perception of and attitudes towards all types of mixed-race. The attitudes towards mixed-race had an influence on the discriminative behavior in all types of mixed-race, and, only in the African-korean, the perception of mixed race affected the discriminative behavior. These results suggest insights for what efforts should be made to improve mixed-race's welfare.

Today, nuclear energy conflict is caused from the dangerous radioactive material. The main party of this conflict are politic and economic systems which deride nuclear energy, and the persons concerned which it oppose and the anti-nuclear environment group. If the nuclear waste is transported from one nation to another nation, multi national anti-nuclear group appears as conflict party. We call this domestic and transnational risk communication new social movement. From the viewpoint of system theory, the new social movement can mean the offensive development of self-reference which withstand the "technicalization of communication" through the "symbolically generalized communication media" like money and power. By comparing Northeast Asia and Europe, the nuclear energy conflict did not show a big difference in the selection of nuclear waste storing site. In the Northeast Asia, when Taiwan exports the nuclear waste to North Korea, the international conflict broke out. In Europe, Germany has a hard experience with the construction-plan for the re-treating plant that produces the plutonium from the dangerous nuclear waste, and with the transnational transport of the nuclear waste. The new social movement aims the global paradigm which is able to guarantee the subtainability of ecological environment. The nuclear conflict in the "world risk society" is solved through the "discourse-alliance" which accomplishes sub-politics by crossing the border of class, nation and system.

This study is designed to explore the function of Twitter as a campaign platform during election campaign. For exploring the function of Twitter the form of tweet, the type of information on tweet and the way of opinion expression via Twitter were discussed by content analysis. This study finds, first, that, netizens express their opoinion of candidates without foundation and with emotional reactions. Second, they showed somewhat conflictive reactions according to their supporting candidates. This study conceptualized various kinds of public as 'blindly support public,' and 'blindly opposition public' in case of Park's supporters, 'rational support public,' and 'critical opposition public' in case of Na's supporters. Third, Park's supporters debated Na candidate's attitude of debate and her appearance blindly without foundation. Na's supporters argued Park's attitude of debate and his ignorance of Seoul Metropolitan government's policy blindly without foundation. Finally, this study discussed the relationship between the political discourse according to netizens' supporting via Twitter and the results of election. Park whose supporters attacked the opposing candidate by blaming her appearance and her attitude of debate won the election. Na didn't overcome her negative images. For her Twitter functioned as a media which is spreading negative factors about her. In conclusion, Twitter as a campaign platform during election times plays a key role in discussing candidates. However, netizens need to express their opinions with foundation and the candidates have to consider negative issue management. This study highlights the importance of peripheral factors which have a decisive effect on the results of election. The results of this study is useful for building political campaign strategy by candidates.

As the network environment develops and speeds up, a lot of smart devices is developed, and a high-speed smart society can be realized while allowing people to interact with objects. As the number of things Internet has surged, a wide range of new security risks and problems have emerged for devices, platforms and operating systems, communications, and connected systems. Due to the physical characteristics of IoT devices, they are smaller in size than conventional systems, and operate with low power, low cost, and relatively low specifications. Therefore, it is difficult to apply the existing security solution used in the existing system. In addition, IoT devices are connected to the network at all times, it is important to ensure that personal privacy exposure, such as eavesdropping, data tampering, privacy breach, information leakage, unauthorized access, Significant security issues can arise, including confidentiality and threats to facilities. In this paper, we investigate cases of security threats and cases of network of IoT, analyze vulnerabilities, and suggest ways to minimize property damage by Internet of things.

Interoperability and inter-working in the various network and media environment with different technology background is very important to enlarge the opportunity of service access and to increase the competitive power of service. The ITU-T and advanced counties are planning ahead for provision of GII enabling user to access advanced global communication services supporting multimedia communication applications, embracing all modes of information. In this paper, we especially forced the heterogeneity of end user applications for multimedia networking. The heterogeneity has several technical aspects, like different medium access methods, heterogeneous coding algorithms for audio-visual data and so on. Among these elements, we have been itemized bit rate shaping algorithm on the compressed moving video. Previous manipulations of video has been done on the uncompressed signal domain. That is, compressed video should be converted to linear PCM signal. To do such a procedures, we should decode, manipulate and then encode the video to compressed signal once again. The traditional approach for processing the video signa1 has several critical weak points, requiring complexity to implement, degradation of image quality and large processing delay. The bit rate shaping algorithm proposed in this paper process the manipulation of moving video on the completely compressed domain to cope with above deficit. With this algorithms. we could realized efficient video bit rate shaping and the result of software simulation shows that this method has significant advantage than that of pixel oriented algorithms.

This paper proposes a new terrestrial 3DTV broadcasting standard specification based on synchronization with non-real-time contents in order to overcome quality limitations of the current 3DTV services that are arisen from the limited bandwidth of the legacy broadcasting channel. In the services using the proposed specification, one view sequence of a stereoscopic video content is delivered as a non-real-time content in idle time, and the other view sequence is transmitted in real time broadcasting signal, thereafter two sequences are synchronized in a receiver for display. Thus, it is possible to provide higher-quality stereoscopic video content services than the current 3DTV services. In order to realize these services, a new mechanism is required which enables synchronization between the data that are from different transmission media and time. Therefore, this paper suggests a solution by multiplexing the synchronization signals of non-real-time contents into broadcasting signals with real-time streams together. This solution can provide a accurate synchronization mechanism by minimum updates of legacy broadcasting systems while maintaining compatibility with legacy services.

Using the Korean environmental input output analysis, this paper provides the emission intensities of the chemicals, especially, the toxic and carcinogenic substances, by linking the structure of demand, and the policy mix to abate these substances emissions. Acording to the results, Industries with the highest total emission intensities(TEI) of toxic substances are ranked : Printing and reproduction of recorded media(21), Other transportation equipment(26), Pulp and paper(11), Leather and fur products(9), Fiber yarn and fabrics(7). And the highest TEI of carcinogenic substances are Wood and wooden products(10), Motor vehicles and parts(25), Plastic and rubber products(15), Audio, video and communications equipment(23), etc.. The economic factors of changing these emissions are emission intensities and final demands. The effective combinations of policy instruments to abate these emissions are varied by the industries and substances. For example, Government need to execute the effective TEI management in the Fiber yarn and fabrics(7) sector, and, in furniture(27) sector, the reduction of final demand is more effective.

Recently, DVC (Distributed Video Coding) is attracting a lot of research works since this enables us to implement a light-weight video encoder by distributing the high complex tasks such as motion estimation into the decoder side. In order to improve the coding efficiency of the DVC, the existing works have been focused on the efficient generation of side information (SI) or the virtual channel modeling which can describe the statistical channel noise well. But, in order to improve the overall performance, this paper proposes a new scheme that can be implemented with simple bit operations without introducing complex operation. That is, the performance of the proposed scheme is enhanced by using the fact that the Wyner-Ziv (WZ) frame and side information are highly correlated, and by reducing the effect of virtual channel noise which tends to be clustered in some regions. For this aim, this paper proposes an efficient pixel-domain WZ (PDWZ) CODEC which effectively exploits the statistical redundancy by using the code conversion and Gray code, and then reduces the channel noise by using the bit interleaver. Through computer simulations, it is shown that the proposed scheme can improve the performance up to 0.5 dB in objective visual quality.

This study aims to compare global policies on ICT accessibility and to suggest possible solutions that help to enhance ICT accessibility for socially disadvantaged groups. The results indicated that related laws and standards in Korea are relatively well established than Asian countries' whereas they need improvements when compared to the US or the UK. Particularly, in spite of rapid development in information communication technology industry, incorporating the definition of newly developed technologies into existing laws related to ICT accessibility seemed slow that caused reluctancy of related parties to address accessibility issues the new technologies create. In addition, Korean government seems less effortful to develop policies and standards apart from web and mobile application accessibility. In order to resolve the problems, firstly, the period or process of enacting and amending laws can be shorten. Next, a government affiliated research institute can be established to do research and develop ICT accessibility related to user scenarios so that effective policies and standards could be readily provided. Even though other possible solutions can be suggested, what is more important than that is that any interested parties should sustainably make efforts to provide equal opportunities for the underserved populations.
