Nowadays, online reviews have become a common word of mouth that many users produce and consume. Posting online reviews is a kind of job that consumers do themselves. Since posting online reviews is not mandatory, it entirely relies on the consumer's voluntary willingness. In this respect, this study aims to describe the motivation for posting online reviews and their behavior processes, such as why online reviewers generate reviews and what types of reviews they create. In this study, we have conducted an in-depth study with 18 participants who have experience in posting reviews. By analyzing interview manuscripts from the grounded theory method approach, we have ultimately presented motivating factors for review posting (mutual reciprocity, material rewards), determinants of review browsing (trust toward review contents, preference for review format), and shadow work (a job that must be done, voluntary data production, consumer's share). We have also proposed the dynamics between core dimensions for theorizing a cycle process of review production and consumption. Our findings could bridge the gap in the existing online review research and offer practical implications for platform companies that need review management.

Internet enables collective communications between social members and contributes to form sound public opinions and to develop democracy while it has negative aspect to distribute massively crime by illegal posting which is forbidden by the Criminal Act. Criminal actors who involve to diffuse information on Internet consist of three categories of information provider, user and internet service provider. Illegal posting generated on Internet is originated from IP and the criminal regulation on it is useless and meaningless because of its countless of users and ambiguous boundary with liberty for expression. Accordingly, the only criminal policy means to prevent danger by illegal posting on Internet is to regulate ISP which saves illegal posting and mediates contacts among users. In spite of it, legislation to regulate ISP is unprepared. The prudent legislative review should be done. And it should be accordance with the doctrines of propriety and vagueness of the principle of "nulla poena sine lege".

The information on SNS, which is created by the forms of postings and comments, is being magnified and redistributed to news media expanding its impacts on real words. This amplifying effects of SNS comments have been increasingly discussed but there still lacks the answers for which dimensions of information is magnified, and what affects the direction and the degree of the amplification. This study, therefore, explores the detailed dimensions that are magnified by SNS comments and how SNS posting structure and social network characteristics affect them by using sentiment analysis. By analyzing 2,378 Facebook postings and news articles and their 26,312 SNS and 74,730 news site comments, this study shows that SNS comments magnify the sentiments of the posting articles they are attached to. In comparison to news site comments, SNS comments magnify the cognitive and social dimensions more than the news site comments. In the affective dimension, they tend to magnify only the positive emotion more than news site comments. Also, the findings reveal that whether the article in the posting is written by the posting owner affects the degree of amplification when the comments are remained positive or switched positive, while the opposite determines the amplification when comments remain negatively, suggesting that the user relationship in social network is the important factor that affects the direction and the degree of the information amplification in SNS.

As the influence of online reviews on consumer decision-making increases, concerns about review manipulation are also increasing. Fake reviews or review manipulations are emerging as an important problem by posting untrue reviews in order to increase sales volume, causing the consumer's reverse choice, and acting at a high cost to the society as a whole. Most of the related prior studies have focused on predicting review manipulation through data mining methods, and research from a consumer perspective is insufficient. However, since the possibility of manipulation of reviews perceived by consumers can affect the usefulness of reviews, it can provide important implications for online word-of-mouth management regardless of whether it is false or not. Therefore, in this study, we analyzed whether there is a difference between the review evaluated by the consumer as being manipulated and the general review, and verified whether the manipulated review negatively affects the review usefulness. For empirical analysis, 34,711 online book reviews on the LibraryThing website were analyzed using multilevel logistic regression analysis and Poisson regression analysis. As a result of the analysis, it was found that there were differences in product level, reviewer level, and review level factors between reviews that consumers perceived as being manipulated and reviews that were not. In addition, manipulated reviews have been shown to negatively affect review usefulness.

Purpose: This study developed and evaluated a systematic intervention among medical ICU nurses for preventing ventilator-associated pneumonia (hereafter VAP). Methods: A VAP prevention program was proposed based on a literature review, revised to fit the target situation, and validated. It was composed of one-time interventions including education, pamphlets, hand cultures, and a quiz event, as well as repeated interventions such as posters, reminders, posting hand culture results, and performance feedback. A simulated control group pretest-posttest design was used to verify the effectiveness of the VAP control program. The incidence of VAP among ICU patients was measured both during 3 months before (n=80) and during 3 months after (n=75) intervention. Results: The VAP prevention program's effectiveness, with a pre-intervention VAP rate of 17.38 and post-intervention rate of 11.04 per 1,000 ventilator days, showed a clinical tendency to decrease, but the difference was not statistically significant (p=.750). Conclusion: A VAP prevention program of multiple interventions can be useful in decreasing the VAP rate. Given that the monthly decrease in the VAP rate was not considered statistically significant, long-term research needs to be done. Additionally, since this study targeted only nurses, it is suggested that future research targets other health care workers who can influence VAP rates.
