For consumers making health decisions, Wikipedia is a popular source for health information. This study investigated major factors influencing consumer satisfaction with Wikipedia medical/health articles. Using a crowdsourcing method, data were collected from 322 adults who read/edit English Wikipedia medical/health articles and reside in the US. The results showed that the presentation of information was the most influential factor. Trustworthiness was the second most important factor for consumer satisfaction with the quality of information, followed by reliability, and topic coverage. Study participants did not consider other factors such as accuracy and currency to be crucial factors. Moderating effects of the control variables such as editing experience with Wikipedia articles, gender, and age were also examined to enhance the internal validity of the study. Implications for the Wikipedia editor community and researchers, and directions of future research are presented.

사회적 의제 설정 영향력을 지닌 미디어인 언론 기사와 블로그 포스트에서 농촌태양광이 어떻게 다루어지고 있는지 분석하기 위해 텍스트 마이닝 방법을 활용하였다. 농촌태양광을 키워드로 웹스크래핑을 통해 기사와 블로그 포스트의 텍스트 자료를 수집하고, 이에 대해 감성분석과 토픽모델 기법을 적용하여 연구를 수행했다. 감성분석 결과 농촌태양광에 대한 텍스트에서 두 매체 모두 긍정적인 입장을 가지는 비율이 높았는데, 블로그의 경우 기사에 비해 부정적인 내용을 담은 텍스트의 비중이 훨씬 낮은 것을 확인할 수 있었다. 그리고 토픽모델링 결과로 긍정 기사는 정부의 보급계획 관련 토픽들의 비중이 컸고, 부정 기사는 다양한 토픽들의 비중이 고르게 분포하였다. 블로그는 긍정 포스트의 경우 농촌 지역 설치 관련 토픽들이, 부정 포스트는 환경 피해 관련 토픽들이 가장 큰 부분을 차지했다. 기존에 별개로 이루어지던 감성분석과 토픽모델링을 결합하는 연구 방식을 제시함으로써 농촌태양광에 대한 이슈를 효과적으로 파악할 수 있었다.

With the development of the Internet and the increase of smart phones, various services considering user convenience are increasing, so that users can check news in real time anytime and anywhere. However, online news is categorized by media and category, and it provides only a few related search terms, making it difficult to find related news related to keywords. In order to solve this problem, we propose a method to recommend related documents more accurately by applying Doc2Vec similarity to the specific keywords of news articles and weighting the title and contents of news articles. We collect news articles from Naver politics category by web crawling in Java environment, preprocess them, extract topics using LDA modeling, and find similarities using Doc2Vec. To supplement Doc2Vec, we apply TF-IDF to obtain TC(Title Contents) weights for the title and contents of news articles. Then we combine Doc2Vec similarity and TC weight to generate TC weight-similarity and evaluate the similarity between words using PMI technique to confirm the keyword association.

Objective: The aim of this study was to investigate the effect of acupuncture on migraine prophylaxis. Method: Articles were searched from the online databases: PubMed, OASIS, NDSL, and RISS. The search keywords were "migraine prophylaxis" and "acupuncture." The inclusion criterion was randomized clinical trial. The exclusion criteria were in vivo, vitro, and review articles. Results: Eighty-nine articles were found among those published until March 2019. After reviewing the title, abstract, and original article, 10 articles were selected to show the effect of acupuncture for migraine prophylaxis. Conclusion: The effect of acupuncture for the frequency and number of days of a migraine and for the intensity of the pain seems to be effective, but the mechanism does not appear to be clear. Therefore, further research is needed in future acupuncture for migraine prevention.

This research investigates the media consumers' behavior with behavioral economics perspective, especially regarding TV content viewers' behavior; how do online communications influence TV viewers' decision when choosing a new TV content among options. We focus on quantity and attribute of comments or reactions on the online news articles. We analyze that online communications data, which were generated before the first broadcast, affect the TV content consumers' choice for a new TV series. Here we identify a predicted utility, experienced utility and distinction bias in TV media consumption to find the effectiveness of the first viewing choice on whole TV series' episodes. To avoid the crucial influence by exogenous factors, such as season and social issue, the test was done with specific conditions. This research found that the total number of reactions to the comments by itself positively affects the audiences' decision-making behavior for a new TV content choice. This influence was regardless of favor/ non-flavor reactions. This study contributes to the literature on media economics and management by exploring the media content users' consuming behavior and making a first step for finding an important influencer on the media content consumption.

Anonymity is one of the key factors that influence communication and the work behaviours of people. It is even more evident in an online community where the role of anonymity can be akin to a double-edged sword: it can increase participation while at the same time having detrimental effects due to irresponsible and disruptive behaviour. Most studies on anonymous participation in groups or communities have reported this ambivalent view of anonymity: positive or negative. Furthermore, the effects of anonymous participation may be different in a dynamic sense because the task characteristics of participation can vary across time. In this study, we hypothesise that the effects of anonymity in online collaboration differ across the stages of collaboration. We analysed 2,978 featured articles on the English-language Wikipedia website and investigated the contributions of anonymous participants. While the contributions of anonymous participants were negative to collaboration efficiency as a whole, the negative effect of anonymous participants was stronger in the earlier stage than the later stage of collaboration. These findings indicate that the effect of anonymity has two sides in terms of collaboration efficiency in the same collaborative environment.

Now more than ever, many journalists are using hospitals' homepages for articles about hospitals, their mission, research, and events. Therefore hospitals' homepages have to be planned and constructed for journalists. The purpose of this study is to investigate hospitals' online media relations through analysing homepages. For investigating specifically, this study compares hompages of hospitals in Korea and hospitals in USA. This study uses four categories; basic media relations tools, useful information, interactive communication tools, and ease of use for journalists. The result of this study shows that hospitals' homepages in Korea are needed to improve for building with journalists. The hospitals' hompages have to be constructed by a variety of materials; press room, image and graphic archives, multimedia resources, and interactivity or responsiveness. This study suggests that the hospitals' homepages have the potential to achieve the desired public relations objective but are not commonly being used to their full potential in media relations.

This study evaluates the accuracy of corrective feedback from Grammarly, an online grammar checker, on essays written by cyber university learners in terms of detected errors, suggested replacement forms, and false alarms.The results indicate that Grammarly has a high overall error detection rate of over 65%, being particularly strong at catching errors related to articles and prepositions. In addition, on the detected errors, Grammarly mostly provide accurate replacement forms and very rarely make false alarms. These findings suggest that Grammarly has high potential as a useful educational tool to complement the drawbacks of teacher feedback and to help learnersimprove grammatical accuracy in their written work. However, it is still premature to conclude that Grammarly can completely replace teacher feedback because it has the possibility (approximately 35%) of failing to detect errors and the limitationsin detecting errors in certain categories. Since the feedback from Grammarly is not entirely reliable, caution should be taken for successful integration of Grammarly in English writing classes. Teachers should make judicious decisions on when and how to use Grammarly, based on a keen awareness of Grammarly's strengths and limitations.
