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.

Since consumers have difficulty in acquiring information related to products in online, they are apt to use WOM(word-of-mouth). It seems to be more popular and acceptable methods to acquire information about products sold in online. In other words, consumers who visit the Internet shopping-mall can not make a purchase-decision immediately because they have no sufficient knowledge about products. To solve this problem, consumers make use of the service called "online review". The objective of this study is to verify how these reviews can influence attitude toward the message, product and several buying behaviors in the online. In particular, this study focus on the message's sidedness(positive or negative) and objectivity(objective or subjective), because it is expected that consumers are likely to behave differently according to the characteristics of online reviews. Thus, to measure consumer's attitude and buying behavior, this study was examined by 4 types of messages. The results of this study are as follows: First, in the positive-objective message, the message attitude has a stronger effect on purchase intention than other outcomes. Second, in the positive-subjective message, the message attitude has a stronger effect on revisiting intention than others. Third, in the negative-objective message, the message attitude has a stronger effect on purchase intention than others. Hence, it is said that online shopping-mall managers need to understand the effects of multidimensional online review.

Internet is having strong impact on the consumer's decision making process. Information search has been done actively through internet today. The online reviews can be crucial information cue to evaluate the alternarive products. The online WOM(Word-Of-Mouth) effect depends on the characteristics of information sender, receiver, and WOM. This study is to examine the influence of the online word of mouth on the consumer purchase intention and the moderating role of product involvement, consumer regulatory focus and self-efficacy. Positive customer reviews on the products influence the purchase intention positively and negative customer reviews influence it negatively. Moderating role of involvement in the causal relation between the valence of online reviews and purchase intention is tested. In case of positive WOM, it is predicted that purchase intention for high involvement products is higher than that of low involvement. In case of negative WOM, purchase intention for high involvement product is lower than that of low involvement product. And this study invetigate the moderating role of regulatory focus. In case of positive WOM, it is predicted that promotion focus oriented consumers have higher purchase intention than prevention focus oriented consumers. In case of negative WOM, prediction is that prevention focus oriented consumers have lower purchase intention than promotion focus oriented consumers. Then we examine the moderating role of self efficacy in the causal relation between the valence of online reviews and purchase intention. In case of positive WOM, it is predicted that consumers with low self efficacy have higher purchase intention than consumers with high self efficacy. In case of negative WOM, it is predicted that consumers with low self efficacy have lower purchase intention than consumers with high self efficacy. Emprical results support our prediction and four hypotheses derived from our conceptual framework are all accepted. This study suggest that the level of product involvement, consumer regulatory focus and the level of self-efficacy influence the consumer responses of the valence of online reviews. Therefore marketers need to manage online reviews based on the level of product involvement, regulatory focus orientation and the level of self-efficacy of target consumers.

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.

The present study aims to identify the factors that affect the continuous use and discontinuance of the hospital information seeking applications(hospital apps thereafter) by employing the post acceptance model. The surveys were conducted with people who used the hospital apps from October 11 to 18, 2019. Researchers collected 125 valid data and analyzed them by using the structural equation model. The study found that the satisfaction and confirmation of expectation for the hospital apps users had significant effects on intention for continuous use and perceived usefulness, respectively. However, the perceived usefulness did not have a significant effect on the intention for continue use. The present study has identified the variables that influence the continuous use of these innovative technologies. The findings of the study confirmed the post acceptance model by observing the adoption and use of the hospital apps and extended the literature of the post acceptance model by discussing the unique characteristics of the hospital apps that satisfy the urgent help-seekers under emergency situations or the information needs emphasizing promptness. In addition, based on the benefits and limitations of hospital apps reported by consumers, the study provided practical implications for designing more user-friendly apps to hospital app developers or managers.
