  • Online reviews play an essential role in the consumer's purchasing decision-making process, and thus, providing helpful and reliable reviews is essential to consumers. Previous online review helpfulness prediction studies mainly predicted review helpfulness based on the consistency of text and rating information of online reviews. However, there is a limitation in that representation capacity or review text and rating interaction. We propose a CNN-RHP model that effectively learns the interaction between review text and rating information to improve the limitations of previous studies. Multi-channel CNNs were applied to extract the semantic representation of the review text. We also converted rating into independent high-dimensional embedding vectors representing the same dimension as the text vector. The consistency between the review text and the rating information is learned based on element-wise operations between the review text and the star rating vector. To evaluate the performance of the proposed CNN-RHP model in this study, we used online reviews collected from Amazom.com. Experimental results show that the CNN-RHP model indicates excellent performance compared to several benchmark models. The results of this study can provide practical implications when providing services related to review helpfulness on online e-commerce platforms.

  • Six Sigma methodology has been evolved since it was first introduced in late 1980's and the number of company which adopts Six Sigma is getting increased. Therefore, it is timely that ire review research papers on Six Sigma extensively. We review 85 papers published in Korea by April 2006 and classify them based on research contents and methodology. We suggest future research issues and fields which can adopt Six Sigma methodology.

  • The environmental issues including domestic measures to protect public life or health are generally easy to bring the tension between the WTO and its member countries. The standard of review, whether de novo review, total deference, or somewhere in between, is largely important in the WTO's adjudicating mechanism because it is closely related to the appropriate balance of power between sovereign nations and the WTO: The multilateral trading regime, through the proper standard of review, could harmoniously operated without interest conflicts among the member countries and at the same time between the WTO and the member countries. Irrespective the important function of the standard of review in the WTO judicial system, applicable standard of review has not been established in the current SPS Agreement. Furthermore, the nature of the SPS Agreement related in scientific factors, such as scientific experiment, data and assessment prevents the WTO's panel from applying consistent standard of review. Considering the judicial demand for the moderate treatment of the case under the SPS Agreement, this paper explores appropriate standard of review applicable the SPS-related environmental measures, particularly, by analysing the recent SPS-related dispute, US-Hormones Suspension.

  • As a new academic publication model is attempted to improve the transparency, efficiency, and speed of scientific knowledge production and distribution, the open peer review platform for verification and openness of peer review history is also activated. Publons is a global platform for tracking, validating, disclosing, and recognizing the peer-reviewed histories of more than 3 million researchers worldwide. This study analyzed the review activities of 579 researchers from domestic universities who are actively reviewing international journals through Publons. As a result of the analysis, first, researchers from domestic universities who actively review international academic journals were found to be in the fields of medicine and electrical and electronics, and in most fields, assistant professors or higher with high WOS indexed research papers are participating. Second, there was a long-tail phenomenon in which a small number of reviewers with extremely high number of review papers existed in all academic fields, and there was no significant difference in the number of review papers and review report length depending on the nationality, academic status, and age of the reviewers. Lastly, although there was a weak correlation between the amount of papers reviewed by reviewers and the number of published papers, it was found that researchers with an extremely large number of reviews do not necessarily produce as many research papers.

  • A book review expands readers' choice of resources by providing them with the contents and bibliographic data of various books. It also functions as a reader support service designed to enrich their reading experiences. In particular, in the field of children's reading, literary devices are used to convey knowledge and information to children. Therefore, a review for a children's book should help children follow a book with further readings so that they can expand their literary imagination through comparative reading. In light of the above, this study looks into the case of a children's story entitled Little Red Riding Hood to identify the points that should be addressed in the "Literature Comparison" section of a book review in order to suggest further readings to readers. First, the review should provide an objective description of the content of Little Red Riding Hood. Second, it should explain the literary value of the reviewed book and the discourse that surrounds it so as to analyze its unique features that separate it from other literary works. Third, the review should provide bibliographic information on other works that use narrative structures adapted from those of Little Red Riding Hood. Fourth, it should broaden readers' choice and access by introducing, if any, works adapted from Little Red Riding Hood into other media.

  • Background: This study aimed to examine whether cases of punishing false claimants threat general physicians to check their medical cost claims with care to avoid being suspected, and identify empirically general deterrence effects of the on-site investigation system in the Korean National Health Insurance. Methods: 800 clinics were selected among a total of 15,443 clinics that had no experience of on-site investigation until June 2007 using a stratified proportional systematic sampling method. We conducted logistic multiple regression to examine the association between factors related to provider's perception of on-site investigation and high level of perceived deterrence referring to fear of punishment after adjusting provider's service experiences and general characteristics. Results: The probability of high perceived deterrence was higher 1.7 times (CI: 1.13-2.56), 2.73 times (CI: 1.68-4.45) each among clinics exchanging the information once or more per year or once or more for 2-3 months than among clinics no exchanging the information about on-site investigation. Also, the probability of high perceived deterrence was higher 2.27 times (CI: 1.28-4.45) among clinics that knows more than 3 health care institutions having experienced an on-site investigation than among clinics knowing no case. Conclusion: A clinic knowing more punishment cases by onsite investigation and exchanging more frequently information about on-site investigation is likely to present high perceived deterrence. This result will provide important information to enlarge preventive effects of on-site investigation on fraud and abuse claims.

  • Background: The recent revision of South Korea's Mental Health Law emphasizes the role of the Mental Health Review Board. For this study, we examined the current status of continuing hospitalization judgement in Mental Health Review Board at the national level and aimed to determine the directions of improvement. Methods: Using a qualitative case study as the research method, we interviewed 30 Mental Health Review Board members and analyzed the results. Results: Each municipality had very different continuing hospitalization judgement methods. In our systematic review, which consisted of document inspection, we identified reliability problems due to limitations in Mental Health Review Board's operating systems, discharge orders, etc. Additionally, continuing hospitalization judgement needs to improve the objectivity, fairness, and effectiveness of their screening examinations. Conclusion: Based on the results of this study, we suggest policy proposals to improve these systems, such as standardizing examination processes, strengthening on-site inspections, increasing the independence and neutrality of judgment in Mental Health Review Board, building community mental health infrastructures, and establishing integrated management systems.
