현재 국내 산업계에서는 임금인상과 원화절상이라는 이중부담으로 많은 어 려움을 겪고 있으며 국제화 시대를 맞이하여 이제는 생산기술의 발달과 함 께 관리기술도 상응하여 진보하지 않으면 안될 처지에 몰리고 있다. 이러한 요구에 대하여 기존의 수작업에 의한 보수적인 실적위주의 관리방식에서 탈 피하여, 컴퓨터를 사용하는 종합적인 관리체계를 구축하려는 노력이 국내의 많은 기업에서 이루어지고 있다. BASC(Business Application Software Company)에서는 이러한 요구에 부응하고자, 한국기계연구원과 공동으로 MRP(Manufacturing Resources Planning, MRPII) 기법을 이용하여, 전체 11 개의 모듈을 갖는 종합 생산관리 시스템을 구축하였다. 본 사례연구에서는 시스템의 전체 구조와 모듈별 기능 및 모듈간의 인계를 설명하고, 아울러 이 시스템을 구축하게 된 동기와 프로젝트의 진행 과정을 상술하고자 한다. 여 기에는 시스템 구축을 위한 system 개발 구성원과 소프트웨어의 개발 배경 등이 포함되어 있다. 마지막으로는 현재 중소기업에서 적용할 시 발생한 여 러 문제점과 이에 대한 해결방안을 설명하고, 추후에 계속된 개선 방향에 대 하여 논하고자 한다.

현대 기업에서는 다양하고 복잡한 업무 프로세스가 일반화 되어있고, 그에 따라 동일한 작업을 여러 장비 즉, PC, 노트북. PDA등 다양한 장비에서 하기를 원하는 사용자들의 요구가 늘어가는 추세이다. 하지만 대부분의 기업에서도 동일한 업무 프로세스를 유지보수나 재개발 하는데 있어서 많은 시간과 비용이 투자되어온 것이 사실이다. 본 논문에서는 이 같은 문제의 해결방안으로 최근 기술인 닷넷 아키텍처를 기반으로 연구된 자료를 토대로 기업 환경에 맞는 재사용성을 강조한 클래스를 구현하고 기존에 대부분의 기업에서 구현되고 있는 데 이터계층, 비즈니스 계층, 유저인터페이스 접근계층으로 분류되는 3-Tier계층 모델에서 한 단계 진보한 닷넷 아키텍처를 응용한 새로운 기업환견에 맞는 닷넷 솔루션 모델을 제시함으로써 닷넷 슬루션의 성능과 팀 개발 업무에서의 비용과 시간을 개선시킬 수 있다는 것을 증명한다.

This paper investigates the role of perceived income hierarchy and political affiliation in individual attitudes toward environmental protection. Estimation results show that rises in perceived income hierarchy increase the possibility of agreement to an increase in taxes to prevent environmental pollution in general, but not linearly increase it. As individuals are more satisfied with the financial situation of their household, they are more likely to agree to an increase in taxes. These results imply that individual attitudes toward environmental protection can be deteriorated even though average household income level increases, if either the degree of financial satisfaction decreases or income inequality worsens. We find that there is no difference between the liberals and the conservatives on the likelihood of paying additional tax to prevent environmental pollution. This result differs from the cases of Western society, which indicate that the liberals are more likely to pay for environmental protection.

This study aimed to investigate the main characteristics of the COVID-19 vaccine-related videos spread on YouTube and differences in user responses in the infodemic situation caused by COVID-19. As a result of content analysis of 579 videos related to the COVID-19 vaccine, it was found that all of the false information was written by individual channels. Institutions, organizations, media companies, and government channels reported spread of false information as well as fact-oriented reporting. The progressive channel had a high percentage of positive sentiment in favor of vaccination, and the conservative channel had a high percentage of negative emotion against vaccination. After the vaccination started, the number of videos on government channels increased, and it was found that the number of videos with positive emotions increased. Results of regression analysis of video characteristics that affect the number of likes indicated that personal expert videos and videos from progressive channels received more likes. Combining the research results, we propose a plan to promote government policies regarding the COVID-19 vaccine using social media.

Samul nori/Pungmul-gut is the symbol of ethnic identity for the Koreans abroad. It is the representative diaspora musical genre which is performed many cultural events held by Koreans. It is, at the same time, a global music which is appreciated by not only the Koreans but also the foreigners. Many musical communities in various countries exhibit the cultural migration through the discourse of 'tradition/variation' and 'authenticity/hybridity' in the course of the acculturation and enculturation of samul nori/pungmul-gut. The pungmul-pae 'Bichoe June' active in Toronto, Canada was organized by a foreign performer. For the foreigners pungmul-gut is easy to access as a genre of world music. As a percussion ensemble, it is easy to learn for the foreigners. The pungmul-pae 'Bichoe June' is a 'music community' consist of the Koreans and foreigners. The band tries to preserve the traditionality and authenticity of the Korean music. There is no variation or hybridity in its music since the member still learns the authentic music through various available textbooks and internet sites. Through the participation of the Koreans and foreigners, the band stimulates the globalzation of the pungmul-gut. The enculturation of the pungmul-gut is exhibited in two performances held by the band. One was host by the Canadian progressive group and the other was by the Korean conservative community. The former understood the nature of pungmul-gut as the music of the common people. The latter, however, accepted the music as the representative traditional music but was not easy to enjoy the 'noisy' music. In other words, the positive/negative acceptance of the pungmul-gut depends of the ideological nature of the listeners rather than the ethnical nature.

This study, expending the existing concept of hostile media perception to biased media perception, empirically examined the effects of TV audience's political disposition(liberal, neutral, conservative) and broadcasting company's political disposition perceived by the audience(liberal, neutral, conservative) on evaluations of the broadcasting channel(interestedness, diversity, creativity, reliability, usefulness, fairness, public interest). With the nationwide online survey data from 624 adult audiences, a broadcasting company evaluated as the most neutral in political disposition at the moments of data gathering was selected and respondents' evaluations of the broadcasting channel were analyzed in a two-way factorial multiple analysis of covariance(MANCOVA). The results showed that the perceived political disposition of the broadcasting company affects audiences' evaluations of the channel while audiences' their own political dispositions do not. In addition, due to the interaction effects between audience's and broadcasting company's political dispositions, congruency in political dispositions led to positive evaluations(congenial media perceptions) while incongruency led to negative ones(hostile media perceptions). Based on these results, theoretical and empirical implications were discussed in terms of the formation of attitudes toward TV broadcasting channels.

Analysis research was conducted on the 'Chosen Ilbo,' 'Donga Ilbo,' 'Hankyoreh' and 'Kyunghyang Newspaper' on news reporting frame and sources regarding the North Korean population's living and status of their respective conditions throughout South Korean administrations of Kim Dae-jung, Roh Mu-hyuen, and Lee Myung-Bak. Resulting first and second frame analyses showed that the four newspapers showed clear distinctions in their execution and attitude in their reports in accordance to the philosophies of each 'progressive/left-wing newspapers' and 'conservative/right-wing newspapers'. Moreover, the first and second analyses showed that the reports mimicked each individual presidential administration and their political policy regardless of the newspaper's political voice. In terms of the usage of 'anonymous sources,' conservative newspapers were found to use them more frequently than their counterpart, the liberal newspapers. In conclusion to the overall analyses, with the continued tension between the International community and North Korea, the reports of North Korean inhabitant activities are inevitably portrayed in a negative tone in effort to plant a distorted view to the South Korean citizens. Furthermore, this manipulation of the press may affect the credibility of South Korean press in terms of the topic of North Korean culture.

This study aims to describe the reporting patterns of articles on the Emergency Grant for all citizens(EGAC) and compare the reporting attitudes by newspaper companies. The main results are as follows: First, conservative newspapers reported more than four times as much coverage of EGAC as liberal newspapers. Newspaper articles reported during the week of the National Assembly Election Day accounted for about a quarter of the total, and 79.1% of the articles were reported in the political realm of newspapers, and only 2.8% in the social realm. Second, a conservative newspaper reported a critical attitude toward EGAC at 52.6% and favorable articles at 5.3%. On the other hand, in a liberal newspaper, critical articles were 17.1% and favorable articles were 37.1%. The inefficiency of selectivism was reported as the basis for the argument in favor, and concerns about the burden of deterioration in the financial soundness of the opponents were reported the most. Politicians are the most cited sources of information in articles. Finally, in prior to policymaking, the proportion of the media in favor of and against the news was similar, and the proportion of articles with a neutral attitude accounted for more than half. And in the specific method discussion stage, the articles in favor of the article exceeded the proportion of articles on the opposite side.
