Recently, most of the users can easily get access to a variety of information sources about companies, products, and services through online channels. Therefore, the online user evaluations are becoming the most powerful tool to generate word of mouth. The user's evaluation is provided in two forms, quantitative rating and review text. The rating is then divided into an overall rating and a detailed rating according to various evaluation criteria. However, since it is a burden for the reviewer to complete all required ratings for each evaluation criteria, so most of the sites requested only mandatory inputs for overall rating and optional inputs for other evaluation criteria. In fact, many users input only the ratings for some of the evaluation criteria and the percentage of missed ratings for each criteria is about 40%. As these missed ratings are the missing values in each criteria, the simple average calculation by ignoring the average 40% of the missed ratings can sufficiently distort the actual phenomenon. Therefore, in this study, we propose a methodology to predict the rating for the missed values of each criteria by analyzing user's evaluation information included the overall rating and text review for each criteria. The experiments were conducted on 207,968 evaluations collected from the actual hotel evaluation site. As a result, it was confirmed that the prediction accuracy of the detailed criteria ratings by the proposed methodology was much higher than the existing average-based method.

최근 IT기술의 발전에 따라 많은 사람들이 자신들의 여가활동에 대한 경험을 공유하고 있으며, 역으로 다른 사람들의 여가활동에 대한 경험을 참고하여 더 나은 여가활동을 누릴 수 있는 기회를 얻게 되었다. 이러한 현상은 영화, 숙박, 음식, 여행 등 여가활동 전반에 걸쳐 나타나고 있으며, 그 중심에는 여가활동에 대한 정보를 요약하여 제공하는 수많은 사이트가 있다. 대부분의 여가활동 정보 사이트는 각 상품에 대한 평균 평점뿐만 아니라 상세 리뷰를 제공함으로써, 해당 상품을 구매하고자 하는 잠재고객의 의사결정을 지원하고 있다. 하지만 기존 대부분의 사이트는 한 단계의 평가기준에 따라 평점과 리뷰를 제공하기 때문에, 각 평가기준을 구성하는 세부요소에 대한 특징과 평가기준 별 주요 이슈를 파악하기 위해서는 상당히 많은 수의 리뷰를 직접 읽어야 한다는 불편이 따른다. 즉 사용자는 자신이 중요한 것으로 생각하는 평가기준에 대한 조건을 파악하기 위해, 많은 수의 리뷰를 하나하나 읽어보는 과정에서 많은 시간과 노력을 소비하게 된다. 예를 들어 호텔의 접근성, 객실, 서비스, 음식 등 한 단계의 평가기준만을 사용하여 평점과 리뷰를 제공하는 사이트의 경우, 접근성 중 특히 지하철역과의 거리, 객실 중 특히 욕실의 상태를 살펴보고자 하는 사용자에게 필요한 정보를 충분히 제공하지 못하게 된다. 따라서 본 연구에서는 기존 여가활동 정보 사이트의 한계, 즉 평가기준별로 입력된 리뷰를 신뢰하기 어렵다는 점과 평가기준을 구성하고 있는 세부 내용을 파악하기 어렵다는 점을 극복하기 위한 방안을 제시하고자 한다. 본 연구에서 제안하는 방법론은 사용자가 별도의 구분 없이 입력한 리뷰를 그 내용에 따라 평가기준별로 자동 분류하고, 각 평가 기준 별 주요 이슈를 요약하여 제공한다. 제안 방법론은 최근 텍스트 분석에 활발하게 사용되고 있는 토픽 모델링(Topic Modeling)에 기반을 두고 있으며, 각 리뷰를 하나의 문서 단위로 사용하는 것이 아니라 리뷰를 문장 단위로 끊어 개별 리뷰 유닛(Review Unit)으로 분해한 뒤, 평가기준별로 리뷰 유닛을 재구성하여 분석한다는 측면에서 기존의 토픽 모델링 기반 연구와 큰 차이가 있다고 할 수 있다. 본 논문에서는 제안 방법론을 실제 호텔 정보 사이트에서 수집한 423건의 리뷰 문서에 적용하여 6가지 평가기준에 대해 총 4,860건의 리뷰 유닛을 재구성하고, 이에 대한 분석 결과를 소개함으로써 제안 방법론의 유용성을 간접적으로 보인다.

Integrity of authorship and peer review practices are important considerations for ethical publishing. Criteria for authorship, as delineated in the guidelines by the International Committee of Medical Journal Editors (ICMJE), have undergone evolution over the decades, and now require fulfillment of four criteria, including the need to be able to take responsibility for all aspects of the manuscript in question. Although such updated authorship criteria were published nearly five years ago, still, many major medical and specialist journals have yet to revise their author instructions to conform to this. Inappropriate authorship practices may include gift, guest or ghost authorship. Existing literature suggests that such practices are still widely prevalent, especially in non-English speaking countries. Another emerging problem is that of peer review fraud, mostly by authors, but also rarely by handling editors. There is literature to suggest that a proportion of such fake peer review may be driven by the support of some unscrupulous external editing agencies. Such inappropriate practices with authorship malpractices or disagreement, or peer review fraud, have resulted in more than 600 retractions each, as identified on the retractions database of Retractionwatch.com. There is a need to generate greater awareness, especially in authors from non-English speaking regions of the world, about inappropriate authorship and unethical practices in peer review. Also, support of any external editing agency should be clearly disclosed by authors at the time of submission of a manuscript.

Objectives: To explore prevalently used types of medication error and the types of medication error which would be appropriate to be used in Korea. Methods: In depth literature review was performed to explore the mostly used types of medication error in the United States, Canada, Europe, Australia, and Japan. We intended to examine experts' view on the suitability of the types of medication error to be used in Korea. The types of medicati0on error were classified by activity criteria, severity criteria, process criteria, and responsible person criteria based on literature reviews. Results: According to the result of literature review, activity criteria was the most commonly used type of medication error. Ten experts in the area of patient-safety and medication error responded and the top two types of medication error which were appropriate and suitable to be used in Korea were severity criteria and activity criteria. Conclusion: Severity criteria and activity criteria could be recommended to be used as the standard types of medication error in Korea although there are other types of criteria such as process criteria and responsible person criteria.

PURPOSE. The aim of this review was to analyze the evaluation criteria on mandibular implant overdentures through a systematic review and suggest standardized evaluation criteria. MATERIALS AND METHODS. A systematic literature search was conducted by PubMed search strategy and hand-searching of relevant journals from included studies considering inclusion and exclusion criteria. Randomized clinical trials (RCT) and clinical trial studies comparing attachment systems on mandibular implant overdentures until December, 2011 were selected. Twenty nine studies were finally selected and the data about evaluation methods were collected. RESULTS. Evaluation criteria could be classified into 4 groups (implant survival, peri-implant tissue evaluation, prosthetic evaluation, and patient satisfaction). Among 29 studies, 21 studies presented implant survival rate, while any studies reporting implant failure did not present cumulative implant survival rate. Seventeen studies evaluating peri-implant tissue status presented following items as evaluation criteria; marginal bone level (14), plaque Index (13), probing depth (8), bleeding index (8), attachment gingiva level (8), gingival index (6), amount of keratinized gingiva (1). Eighteen studies evaluating prosthetic maintenance and complication also presented following items as evaluation criteria; loose matrix (17), female detachment (15), denture fracture (15), denture relining (14), abutment fracture (14), abutment screw loosening (11), and occlusal adjustment (9). Atypical questionnaire (9), Visual analog scales (VAS) (4), and Oral Health Impact Profile (OHIP) (1) were used as the format of criteria to evaluate patients satisfaction in 14 studies. CONCLUSION. For evaluation of implant overdenture, it is necessary to include cumulative survival rate for implant evaluation. It is suggested that peri-implant tissue evaluation criteria include marginal bone level, plaque index, bleeding index, probing depth, and attached gingiva level. It is also suggested that prosthetic evaluation criteria include loose matrix, female detachment, denture fracture, denture relining, abutment fracture, abutment screw loosening, and occlusal adjustment. Finally standardized criteria like OHIP-EDENT or VAS are required for patient satisfaction.

In this study, a comparison between the structural design criteria for a catenary system with the maximum design speed of 100km/h and that of 300km/h was performed in order to establish that of 200km/h. According to the result, catenary design criteria for 300km/h operation is more conservative than that for 100km/h operation. This result shows that higher wind pressure and safety factor are adopted to catenary design for 300km/h operation. So, for the purpose of the economic structural design for catenary system, it is necessary to review the adoption possibility of catenary system for 100km/h operation first. In order to review the adoption possibility for catenary system for 100km/h operation, design criteria for 300km/h operation should be chosen for safer catenary structure.

This study developed selection criteria of small-scales reservoirs, having under $300,000m^3$ storage capacity, for the Emergency Action Plan(EAP) establishment in order to reduce the disaster risks of the reservoir's failures. Those reservoirs are out of ranges of Korean EAP establishment standard, but have potential risk of disasters as they have often failed by the recent extreme rainfall events and earthquakes, causing economical and life losses. The problem of reservoir aging is also one of the reasons of them. In this study, the developed selection criteria of small reservoirs for EAP establishment are storage capacity, embankment height, reservoir age, heavy rain factor and earthquake factor. These criteria were selected based on the review of the existing EAP establishment guidelines, analysis of the past dam failure cases, and the previous related studies. The quantification of these criteria were conducted for the practical applications in the fields, and applied to 67 previous failures in order to investigate the relation of each criteria with these failures. The earthquake factor found to be the highest relations followed by heavy rain factors, combination of earthquake and heavy rain factors, and reservoir age. The classification was made as observation and review groups for EAP establishments based on overlapping numbers of each criteria. This classifications applied to 354 reservoirs designated as having the potential disaster risk by MOIS, and showed 38.4% of observation and 11.9% of review groups. Anticipatory monitoring and regular inspection should be made by professional facility managers for the observation group, and necessity of EAP establishment should be assessed for the review group based on the downstream status and financial budget.
