Many prior studies have been conducted that positive reviews increase the intention to purchase. However, there are very few papers that have studied the impact of review search on purchase satisfaction. It is meaningful to study the impact of review search on purchase satisfaction as it can lead the business successfully by inducing repurchase. There is also no study of how review search have different effects on purchase satisfaction among countries. Given the growing number of cross-border e-commerce, we believe that the need for research is high because identifying these differences between countries can have a very important impact on a company's successful overseas expansion. Therefore, in this study, the impact of positive and negative review search on purchase satisfaction and the national impact were set up as a research model. In order to verify this research model, the survey was distributed to those who experienced online purchase in Korea and China, and a total of 234 copies were collected, including 125 copies in Korea, 109 copies in China, and the research model was verified using Smart-PLS structural equation analysis tools. First, positive review search has been shown to positively affect purchase satisfaction. Second, it has been shown that negative review search also has a positive effect on purchase satisfaction. Third, the impact of positive and negative review search on purchase satisfaction was different between Korea and China. While Korea is more aggressive in review search than China due to its high tendency to avoid uncertainty, China is less likely to avoid uncertainty than Korea and is more likely to rely on brand familiarity. Therefore, according to the uncertainty avoidance moderation effect the impact of positive and negative review search on purchase satisfaction was higher in Korea than in China. In this study, Shopping mall managers need to take strategic measures to maximize shopping mall performance by recognizing positive aspects of negative review search on purchase satisfaction. Companies and managers in Korea and China can establish strategies to promote product sales when companies enter the global market.

Purpose: This study aims to examine how to review contents of experiential and utilitarian products (e.g., skincare products) and how to affect review helpfulness by applying natural language processing techniques. Research design, data, and methodology: This study uses 69,633 online reviews generated for the products registered at Amazon.com by 13 Korean cosmetic firms. The authors identify key topics that emerge about consumers' use of skincare products such as skin type and skin trouble, by applying bigram analysis. The review content variables are included in the review helpfulness model, including other important determinants. Results: The estimation results support the positive effect of review extremity and content on the helpfulness. In particular, the reviewer's skin type information was recognized as highly useful when presented together as a basis for high-rated reviews. Moreover, the content related to skin issues positively affects review helpfulness. Conclusions: The positive relationship between extreme reviews and helpfulness of reviews challenges the findings from prior literature. This result implies that an in-depth study of the effect of product types on review helpfulness is needed. Furthermore, a positive effect of review content on helpfulness suggests that applying big data analytics can provide meaningful customer insights in the online retail industry.

Purpose This study analyzed the topic of game review contents and how the characteristics of game reviews affect the reviews helpfulness. In addition, this study explore the content of game reviews according to the game's sales strategy such as early access strategy and releasing without early access. Design/methodology/approach We collected a list of 3,572 action genre games released in 2020. 58,336 online reviews were collected by random sampling 50 reviews in each games, and topic modeling was performed on those reviews. We dynamized the results of topic modeling and analyzed the effect on review helpfulness with multiple regression analysis. Findings The results of analysis indicate that the longer the review is or the shorter the time it is written, the more helpful the review is. In addition the topic with positive and negative review has a significant effect on the review helpfulness. As a result of exploratory analysis, games from early access had relatively fewer reviews of story-related topics than games that were released without early access. These findings can present direct guidelines for collecting specific opinions from customers in the game industry when releasing games.

온라인 리뷰는 소비자의 구매 의사결정에 중요한 역할을 하기 때문에 소비자의 지각된 리뷰 유용성에 영향을 미치는 리뷰 요인을 확인하는 것이 필요하다. 그러나 온라인 리뷰의 유용성에 대한 대부분의 기존 연구는 주로 리뷰 및 리뷰어 속성과 같은 정량적 요인에 중점을 두고 있다. 최근 연구에서는 리뷰 콘텐츠과 언어 스타일이 소비자의 구매 의사결정에 미치는 영향을 조사했다. 또한, 소비자가 의사결정 과정에서 리뷰를 평가할 때 추가적으로 리뷰 텍스트 속성들을 고려해야 한다고 주장하고 있다. 따라서 본 연구는 온라인 리뷰 맥락에서 리뷰 콘텐츠과 언어 스타일이 리뷰 유용성에 미치는 영향을 조사하고자 한다. 추가적으로 리뷰어의 전문성이 리뷰 콘텐츠 및 언어 스타일과 리뷰 유용성 간의 영향관계를 조절하는지 여부를 조사했다. 연구결과 긍정적인 리뷰 콘텐츠는 리뷰 유용성에 부정적인 영향을 미치고, 부정적인 리뷰 콘텐츠와 언어적 스타일은 리뷰 유용성에 긍정적인 영향을 미치는 것으로 나타났다. 리뷰어의 전문성은 부정적인 리뷰 콘텐츠와 언어 스타일이 리뷰 유용성에 미치는 영향을 완화시키는 것으로 나타났다. 본 연구결과는 온라인 전자상거래 기업이 리뷰 유용성에 영향을 미치는 요인을 파악하고 이를 마케팅 전략에 반영하여 기업 매출 성장을 달성하는데 시사점을 제공할 수 있다.

Background : Utilization review has been adopted as a vehicle for cost and utilization control of health care services. Its role was further stressed and expanded through the establishment of Health Insurance Review Agency in 2001. This article is to introduce concept, activities, and effect of utilization review based on the experiences of U.S. and to suggest important characteristics for ideal utilization review activities at the national level in Korea. Method : Twenty-five articles related with utilization review were reviewed after being selected through web site search through Med Line and Richis. Result : Utilization review was introduced mainly for health care expenditure control either by insurer, provider or the third parties under the pressure of increasing health care cost. It's activities can be categorized to prospective, concurrent and retrospective review according to the time of service provision. Based on most of studies, utilization review has been effective in controling rising health care cost and utilization. However it's effectiveness assumes a reimbursement structure of managed care like capitation payment. More worse, it is still unknown it's effectiveness on quality of care. Conclusion : Utilization review should be employed to increase the cost effectiveness of medical care by optimizing quality and patient's outcomes while also attempting to reduce the use of resources. So, it should consider outcomes before expenditures, check for both under and over-use, and construct an structure in which consumption is reduced equitably. Aggressive adoption of utilization review in Korean health care setting with fee-for-service reimbursement structure might not be a cost-effective approach before adoption of prospective payment system such as D.R.G. and capitation.

The Organization for Economic Cooperation and Development, which has continuously evaluated the performance of healthcare systems, has recently invested much effort into hospital performance measurement. The purpose of this paper is to introduce the hospital performance measurement programs operated by international organizations or at the national level based on the OECD's hospital performance project. Health Insurance Review & Assessment service (HIRA)'s quality assessment was analyzed based on the analytical framework of the OECD's hospital performance project. The hospital performance measurement programs of WHO, Canada, Australia, United States and United Kingdom are briefly explored, in view of the conceptual framework, key performance dimensions and indicators that are currently in use. The OECD suggested seven key dimensions of hospital performance: timeliness, efficiency, continuity, effectiveness and appropriateness, staff orientation, patient orientation and safety. The analysis of the quality assessment program of HIRA, which operates 36 diseases and procedures and 347 indicators, shows that the numbers of indicators are relatively small in the areas of safety, patient centeredness and efficiency. Continuity of care and staff orientation are not fully developed also, but the situations are similar in other countries. In conclusion, hospital performance measurement using stable and comprehensive data should be developed to improve overall system performance, and discussions on a conceptual framework that can lay out directions and key performance domains need to take into place.

기록물 공개의 전(前)단계인 공개재분류 업무는 가치있고 중요한 업무다. 그러나 그 의미와 중요성과 별개로 일선 기록연구사에게는 귀찮고 부담스러운 업무이기도 하다. 이에 기록연구사의 업무 부담을 경감해주는 공개재분류 자동화가 제안되기도 했다. 이런 상황에서 국가기록원의 '2020년 공개재분류 결과 건별 입력 위탁사업' 수행 간 공개재분류 솔루션을 활용하였고, 이를 사람이 한 작업과 비교⋅분석해 보았다. 물론 해당 사업은 공개재분류 솔루션에 대한 분석과 연구가 중심인 연구용역 사업이 아니었고, 상용프로그램을 실험적으로 사용해 본 제한적 결과라는 한계는 존재한다. 그럼에도 지능형 아카이브의 공개재분류에 대한 거시적이고 피상적인 논의만 있는 현 상황에서 기록연구사가 활용가능한 공개재분류 솔루션을 실제 사업에서 활용한 결과를 살펴보는 것은 여러모로 의미가 있으리라 생각된다. 본 논문은 공개재분류 솔루션의 활용 사례에 대한 분석을 통해 공개재분류 업무를 경감시킬 수 있는 실질적이고 미시적인 차원의 논의이다.
