The primary objective of this paper investigates whether asymmetric volatility phenomenon is caused by differences of opinion among investors and analyses information availability has an effect on asymmetric volatility. The empirical test period covers recent 6 years from January 4, 2000 to December 29, 2005. Five portfolios have been formed according to information availability(volume and market value). For the purpose of this study, We use TGARCH model, TGARCH-M model and adjusted model which include trading volume as a proxy differences of opinion among investors. The results are summarized as follows ; First, adjusted model analysis shows that asymmetric volatility phenomenon is disappeared or asymmetric coefficient and ratio is decreased than basis model. Second, portfolio analysis shows that the higher volume and market value, the more prominent asymmetric volatility phenomenon. And adjusted model analysis shows the higher volume and market value, the more decrease asymmetric ratio. Over all, assertion that differences of opinion among investors has caused asymmetric volatility phenomenon is regarded as reasonable. And, We see that information availability have great effect on asymmetric volatility phenomenon. We think that theses results can also occur opinion adjustment of optimistic investors. Namely, asymmetric volatility phenomenon can occur difference of information authenticity.

Although concerns about the opinion shopping have been continuously raised in the audit market, there has been little research on empirical evidence on the existence of audit opinions. For this reason, this study empirically confirmed whether the opinion shopping exists. At first, we measured thresholds of audit opinion issuing of two groups(changed or not-changed auditors). After that, the difference analysis was conducted to verify whether the thresholds of the audit opinion issuing was significant difference between two groups. As a result of the study, there was no significant difference in the thresholds of audit opinion issuing between two groups. This result can be interpreted that the audit opinion shopping is not a general phenomenon in the external audit market. The contribution of this study is to empirically confirmed that audit opinion shopping does not exist in the external audit market.

소설미디어의 급증과 함께 온라인 리뷰의 의존성이 급증하는 가운데 사용자의 올바른 의사결정을 저해하는 기만적 의견 스팸 이슈가 새롭게 주목받고 있다. 기존의 의견 스팸 연구는 실제 리뷰와 의견 스팸 간의 차이를 어휘, 품사 또는 감정단어와 같은 표면적 자질을 통해 설명하였으나 그들간의 의미적 연결관계는 고려하지 않았다. 본 논문에서는 1) 의미적 프레임 기반의 텍스트 분석기법을 제안하고, 이를 바탕으로 2) 의견 스팸과 실제 리뷰간의 의미적 차이가 있음을 규명하며 3) 새로운 의미적 프레임 자질을 사용하여 기존의 의견 스팸 분류 성능을 향상시킬 수 있음을 보인다.

한국인은 다양한 의견을 수렴하여 합의에 도달하는 것에 서투른 것 같다. 의견이 다른 것이야 어찌보면 당연하고 오히려 바람직한 것인데, 입장 차이를 줄이고 원만히 합의하는 것은 말처럼 쉬운 일이 아니다. 좀처럼 합의에 이르지 못하는 사람들을 보면 때로는 그들에게는 '합의'라는 DNA가 없는 것이 아닌가 하는 생각마저 든다.

This study aims to explore the structural relationships among experiences of being heard in home and school settings, self-esteem, and human rights awareness. Among the 2017 NYPI Cross-sectional Survey on the Rights of Youth & Children, 6,405 middle and high school students (47.8% females) were used to conduct a structural equation modeling using Mplus. It was found that children who experience being heard in the home or school display higher levels of self-esteem and awareness of human rights. It was also found that self-esteem is more likely to increase awareness of human rights. Self-esteem was also found to mediate the pathway between the experience of being heard at home or school and human rights awareness. In addition, there was no significant difference in path coefficients depending on whether they received human rights education. Practical implications for promoting home and school environments where children's opinions can be heard were discussed.

This study aims to examine the relation between opinion perception and opinion expression by issue types by analyzing online poll results and respective bulletin boards. To find out how opinion poll results affect the public opinion perception cues and opinion expression through the internet, the study applied a method of content analysis to the online contents provided by Naver.com, one of the most popular portal sites in Korea. A total of four issue types, along with 2,250 messages were chosen for analysis. The study results revealed that internet users perceived opinion atmosphere through the poll results and expressed their opinions depending on the issue types. In case of an issue where majority views are manifested as online poll results, users tended to follow that majority views by retaining their initial opinion. Majority opinion by the poll results held a dominant position in bulletin board. The results partially support Noelle-Neuman(1994)'s spiral of silence theory in the context of computer-mediated communication contrary to the belief that anonymity in the cyberspace tends to encourage participation of minority opinion group. According to the findings, people when they perceive their opinion as that of minority are discouraged to express their views even when they are online.

본 연구는 개인주의-집단주의 문화 개념을 도입하여, 타인의 의견이나 집단규범이 내포된 합의정보와 제품의 속성이 나타난 속성정보가 불일치한 상황에 접했을 때 개인의 문화지향성에 따라 정보의 수용과정에 차이가 있는지를 탐구하였다. 본 연구는 접근성-진단성 프레임웍에 근거하여 정보의 수용과정 모델을 개발하고 이를 중국 및 한국의 개별소비자차원에서 검증하였다. 본 연구의 실증분석 결과, 소비자의 개인주의-집단주의 성향에 따라 불일치 정보의 수용과정이 다르게 나타났다. 집단주의 성향의 소비자들은 합의정보의 합의성 지각수준을 높게 지각할수록 합의정보의 집단자아 접근성과 집단동조 진단성 수준이 증가하여 집단의견수용의도가 높아지는 것으로 밝혀졌으며, 속성정보의 속성성 지각수준을 높게 지각할수록 속성정보의 개인자아 접근성과 개인화가치 진단성이 증가하여 개인의견반영의도가 높아지는 것으로 나타났다. 한편, 개인주의성향의 소비자들은 속성정보의 속성성 수준을 높게 지각할수록 개인화가치 진단성 수준이 높아져 개인의견반영의도가 높아지며, 합의정보의 합의성 수준을 높게 지각할수록 집단자아 접근성 수준이 높아져 집단의견수용의도가 높아지는 것으로 나타났다.
