The current study extends previous research by investigating the role of shopping experience and product type within the direction of online reviews and information reliability and product attitude. To test the hypotheses, this study conducted experimental designs. Direction of online reviews and product type were manipulated as between-subject factors. Then participants were classified into high or low group based on their shopping frequency. Dependent variable was information reliability and product attitude. The results indicate that direction of online reviews have a significant effect on both information reliability and product attitude. In addition, consumers' shopping experience also shows a moderating effect between the direction of online reviews and the dependent variables. Furthermore, product type also shows a moderating effect on the information reliability, yet not on the product attitude. The results of this study contribute to the literature as a new attempt to examine the direction of online reviews in the online shopping area. We also indicated the limitations of this study, and suggested the future research directions.

Social changes due to ICT like Big Data, IoT, Cloud and Mobile is progressing rapidly. Now, we get out of the old-fashioned frame was measured at the level of the information society through the introduction of PC, Internet speed and Internet subscribers etc and there is a need for a new type of diagnostic information society framework. This study is the study for the framework established to diagnose and measure post-information society. The framework and indicators were chosen in accordance with the technological society coevolution theory and information society-related indicators presented from authoritative international organizations. Empirical results utilizing the indicators and framework developed in this study were as follows: First, the three sectors, six clusters (items), 25 nodes (indicators) that make up the information society showed that all strongly connected. Second, it was diagnosed as information society development (50.34%), technology-based expansion (25.03%) and ICT effect (24.63%) through a network analysis (ANP) for the measurement of importance of the information society. Third, the result of calculating the relative importance of the cluster and nodes showed us (1)social development potential (26.04%), (2)competitiveness (15.9%), (3)ICT literacy (15.5%) (4) (social)capital (24.3 %), (5)ICT acceptance(9.54%), (6)quality of life(8.7%). Consequently, We should take into account the effect of the economy and quality of life beyond ICT infrastructure-centric when we measure the post-information society. By applying the weighting we should performs a comparison between countries and we should diagnose the level of Korea and provide policy implications for the preparation of post-information society.

The authors examine the characteristics of the counter public sphere during the late Chosun era based on three dimensions: historical, ideological, and analytical. The counter public sphere during the late Chosun era was a lively communicative sphere where the common people, who resisted the premodern ideas and foreign power, tried to overcome the oppressing social and political environment. Although the counter public sphere did not continue to grow during the Japanese colonization era, it provided a basis of the independence movement and the ideological ground for the democratic movement today.

SNS 의 발달로 이를 활용한 제품의 광고가 활발하게 이루어지고 있다. 다양한 제품군 중에서도 사용자의 피부 및 건강의 개선 효과가 나타나는 화장품, 건강보조제 등은 후기 글을 보고 실제 효과를 판단하기에 어려움이 있다. 이는 많은 양의 광고에 가려진 실질적 후기를 찾는 것이 어렵고, 포스팅의 전문을 읽는 것은 비효율적이라는 점에서 기인한다고 할 수 있다. 본 논문에서는 소셜 미디어를 바탕으로 아토피 치료법의 효과를 분석할 수 있는 효과 분석 모델을 개발하고 그 결과를 제시하였다. 먼저 많은 후기가 존재하는 키워드를 기반으로 최대 1000 개의 블로그 포스팅을 수집하였고, 광고성 글을 제외하는 자동 처리 알고리즘을 실시하였다. 다음으로 각각의 후기 글에 나타난 효과를 한눈에 알아볼 수 있도록 점수화하는 효과 분석 알고리즘을 제안하고 실험하였다. 실험결과 감마리놀렌산, 플라즈마, 락토바실러스 등이 긍정적 효과가 있는 치료법으로 나타났다. 본 논문에서 제시한 알고리즘은 제품의 효과를 점수화할 수 있으므로 아토피 치료법에 한정되지 않고, 해당 제품군인 화장품 및 건강보조제 등에 다양하게 적용될 수 있을 것으로 보인다.

스마트폰 시장이 커지면서, 사람들이 하루에 업로드하고 다운로드하는 어플리케이션의 수 또한 급격히 증가하고 있다. 앱스토어와 안드로이드마켓에 등록된 어플리케이션의 종류는 어마어마하며, 사람들은 자신의 생활을 편리하게 해줄 어플리케이션 혹은 재미를 위한 어플리케이션을 다운로드하고자 한다. 하지만 현재 어플리케이션에 대한 평가는 점수로만 이루어져있기 때문에 어느 부분에서 뛰어난지, 어떤 부분의 기능이 떨어지는지는 사용자가 알 수 없고, 특정 기능을 중요시하는 사용자일 경우 별점이 높아도 해당기능이 만족스럽지 않으면 만족감의 정도는 대단히 떨어지게 된다. 그러면 다른 어플리케이션을 받아 같은 작업을 반복해야하는데, 이 경우가 반복될 경우 비용적인 문제뿐만 아니라 사용자에게 매우 번거로운 일이다. 따라서 본 논문에서는 기존 사용자들이 자신이 사용한 어플리케이션에 대해 작성한 후기를 오피니언 마이닝 기술을 적용시켜 각 키워드별, 즉 속성별로 평가하고 긍정/부정 여부를 데이터베이스에 저장하여, 해당 어플리케이션을 검색한 미래의 어플리케이션 사용자에게 시각적으로 정보를 알려주어 사용자의 수고를 덜어주고자 한다. 어플리케이션 다운로드가 매우 단순한 작업이지만, 다운로드 수가 많기 때문에 본 논문의 제안을 적용한다면 비용을 절감시켜 줄 뿐만 아니라 매우 효율적인 작업이 될 것이라 기대한다.
