According to the spiral of silence theory, perception of opinion climates influences willingness to express one's opinion. This study examines the relationship between opinion perception and opinion expression in different regions and issues. The results show that one's opinion and the intensity of opinion affect the expression of opinion about national and regional issues in Busan and Gwangju. People who perceive their opinions as majority are more willing to express theirs about national and regional issues in Gwangju, but not in Busan. Regression analyses show that perceived public opinion does not predict the expression of opinion in both cities. People who perceive their opinions more favorable about regional issue have lower intention to express their opinions than people who perceive their opinions same as others'. In summary, one's opinion and perception bias about controversial issues are important variables influencing expression of opinion, and the influence of perceived public opinion on opinion expression varies in different regions with different distribution of public opinion. This study found 'new hardcores' who perceive their own opinion as minor but more valuable and have the intention to speak out in places more difficult to express.

This study compares the influence of perceived public opinion on Internet users' willingness to expression in real space with in cyber space. In real space, people who perceive their opinions as minority opinion are reluctant to express theirs publicly because of fear of isolation. But cyber space is the anonymous world. So we can expect that people express their opinions freely without the fear of isolation in this space. This study's results provide the support for our expectation. In cyber space, the minority perception group has as the high willingness to expression of their opinion about the abrogation of the Korean Family Rights Raw as the majority perception group. Both of in cyber space and in real space, it is the perception failure group that makes discrepancy in the willingness to expression. This group has the lowest willingness to expression in both space. However, the other predictors of willingness to expression in cyber space are similar to those in real space. Issue salience, Communication apprehension, and Age are the very significant predictors of willingness to expression in both spaces. Sex and ideology are significant predictors in real space, while the frequency of online conversation is the significant predictor in cyber space.

In this study, we empirically investigate the relations between trading volumes and our proxies for information flows and differences of opnion. Econometric methods to analyze the relations in the equity and KOSPI 200 futures markets include Generalized Method of Moment(GMM) and Generalized Autoregressive Conditional Heteroscedasticity(GARCH) models. Major findings from our empirical analyses are summarized as follows; (i) Trading volume in both the equity and KOSPI 200 futures markets varies positively with proxies for information flows. We find that trading volumes in both markets are closely related to firm-specific information rather than market-wide information. (ii) Trading volumes in the equity and KOSPI 200 futures market have positive relations with our proxies for differences of opinion. (iii) Day-of-the-week effect is clear in both markets. Trading volumes in both the equity and KOSPI 200 futures markets tend to be relatively low early and late in the week. (IV) Futures contract life-cycle effect is clear. In other words, futures trading volume increses in the period around contract expiration. (V) In addition, ARCH effect on trading volumes is reported significant enough to take into account. The disturbance of trading volumes in both markets seem to be conditional heteroscedastic.

This study examines how and which direction respondents who participated in 5-point Likert scale surveys change their initial responses when they are given an identical second survey after certain treatments. The research employs three identical questionnaires (first, second and third surveys) to analyze survey results based on group differences, kinds of treatment, survey purposes, and response change direction and the degree. This paper concludes that, first, it is significant that specialist groups do not change their initial responses compared to a general librarian group. Second, there are no differences by survey purpose; however, participants tend to change their initial responses by others' opinions rather than by previous use experiences. Third, participants who initially answered positively tend not to change their responses, and most participants who answered negatively change their initial responses in a positive direction. Fourth, when there are changes, participants change their initial responses by less than two points, and most of them change by one point. Finally, the hypothesis that middle responses change most and that participants who respond at both ends do not change their opinion was rejected by the finding that participants who answered on the negative end tend to change their initial responses in a positive direction.

This study is an application of facebook (FB) as a strategic communication of viral marketing. Old fashioned advertising and public relation in facebook are not effective at social network service(SNS) environment, and a different marketing communication is needed because facebook is essentially oriented for building relationship among people. The study assumes that an opinion leader might exist at facebook and tries to find out how facebook users show a pattern of communication based on level of opinion leadership regarding a product. The findings showed that people with high opinion leadership communicated more actively than people with low opinion leadership. This study will contribute to segment seed consumers using opinion leadership in facebook.

'92.7. 신행주대교 사고 이후 '건설공사 부실방지대책'을 수립하여 관련 제도를 정비하고 건설현장에 대한 불시 점검으로 견실시공 분위기 정착에 노력하여 왔다. 그러나 그동안 정부의 부실방지와 안전확보 노력에도 불구하고, 아직까지 크고 작은 부실이 계속되고 있으며, 삼풍백화점 붕괴와 같은 대형사고에 대한 불안심리가 사라지지 않고 있다. 따라서 지금까지 추진한 제도개선사항이 일선현장에 정착되도록 최선을 다하는 한편, 이해집단간의 의견차이로 추진하지 못한 사항도 과감히 개선할 계획이며, 앞으로 우리 건설업계도 건설시장 개방에 따라 국ㆍ내외 시장에서 생존하기 위해서는 견실ㆍ안전시공과 기술개발 및 업종전문화를 목표로 하고 품질경영을 최우선으로 실시하여 건설공사에 대한 신뢰성을 더욱 확고히 다져 나가야 할 것이다.

현대경제연구원은 지난 5월 16일부터 23일까지 8일 동안 전국 20세 이상의 성인남녀 1,011명을 대상으로 전화설문을 통해 "성장과 복지의 선순환 관련 설문 조사"를 실시하고 그 결과를 최근 발표했다. 설문조사 결과 성장과 복지 중 '성장이 우선'이라는 답변(58.0%)이 많았지만 세대간 차이가 뚜렷하게 나타났다. 2030세대는 '복지가 우선'이라는 응답이 많았으나 40세 이상은 '성장이 우선'이라는 답변이 많았다. 성장과 복지 둘 다 중요하며 함께 갈 수 있다는 의견에 대해서는 '가능하다'는 긍정적인 의견이 77.0%로 부정적인 견해(23.0%)보다 훨씬 많았다. 여기서는 이번 조사결과의 주요 내용을 요약해 소개한다.

의견이나 이해가 서로 맞지 않는 경우 충돌은 발생한다. 유비쿼터스 컴퓨팅 환경에서 서비스를 수행하는 과정에서 발생하는 충돌의 경우 역시, 그 서비스의 요청 및 수행과정에서 발생하는 의견이해의 차이에서 비롯된다. 서비스의 수행을 결심하기 이전에 그 서비스에 연관된 의견이나 이해관계를 파악하고 그들 사이의 이견을 방지한다면, 서비스 사이에서 발생 가능한 대부분의 충돌을 방지할 수 있다. 본 논문에서는 이를 위해 유비쿼터스 컴퓨팅 환경에서 자동으로 서비스를 제공하는 시스템의 입장에서 각 서비스들이 환경과 그 환경 안의 자원들 사이의 관계에 대한 의미를 정의하고 결정함으로써, 다수의 서비스를 충돌 없이 수행할 수 있는 방법을 제안한다.

Generally, the method of the policy analysis has been used for making a policy decision of the development project of the road through the expert interview based on AHP. According to introducing PI, the study of the method of the integrating process for various opinion of the related groups is required. On this study I evaluate what is a difference between the results of integrated process and the AHP analysis on what is major considering factor in decision-making process. From the analysis, each evaluate factor is in level of significance by ANOVA. First, there is a significance level difference between Group A, C and Group B Second, there is also a significance level difference on the result of AHP analysis for each group in order to evaluate by integrated method. Finally, the method of AHP analysis which considers priority factor is expected as to be useful tool on decision-making of various group.

기초의학 강의 요원의 부족은 교육에 대한 부담과 연구활동 위축이라는 이중고를 초래하고 있다. 기초의학 강의의 효율성을 높이기 위하여 다양한 연구 및 해결책이 제시되어 왔으며, 통합강의 역시 그 대안의 하나로서 대두되고 있다. 따라서 본 연구에서는 새롭게 부각되고 있는 기초의학 통합강의에 대한 가상강의(cyber lecture) 적용의 실효성과 타당성을 설문조사와 교과목 운영의 경험을 중심으로 분석하였다. 설문조사에 대해 학생들은 가상강의의 내용, 난이도, 진행 및 멀티미디어 컨텐츠 등에 대해 대체로 만족스러운 의견을 제시하였다. 또한 가상강의가 통합강의 운영을 보완해주는데 효율적일 것이라는 의견과 더불어, 향후 통합강의에서 가상강의의 비중을 학대할 필요성에 대해서도 찬성의견이 반대의견보다 지배적임을 알 수 있었다. 뿐만 아니라, 통합강의 실습의 일부분을 가상강의에서 운영하는 방안에 대해서도 대체로 긍정적이었다. 통계분석 결과, 가상강의에 대해 긍정적이거나 부정적인 의견들은 기초신경학 통합강의 성적이 우수한 학생과 보통이하인 학생들 사이에 유의한 차이를 보이지 않았으나 (${\chi}^2$ 검증 결과), 성적이 우수한 학생일수록 가상강의의 효율성에 대해 긍정적이라는 경향은 알 수 있었다(Spearman 등위상관계수를 산출한 결과). 본 연구결과를 통해 제시된 개선방안과 축적된 경험을 바탕으로 점차 가상강의의 비중을 높이고 강의교수들 간의 유기적 협조가 이루어진다면 가상강의는 향후 기초의학 통합강의 운영의 새로운 패러다임(paradigm)이 될 것으로 사료된다.
