OBJECTIVES: Research on workplace violence has been conducted, but rarely has been organized systematically. In this study, we summarize the definition and classification of workplace violence studies and review the literature on workplace violence. METHODS: Using academic search engines PubMed, Google Scholar and DBpia, we found 856 papers including “workplace violence” and “adverse social behavior” AND workplace in the title published until December 2018, and 208 papers were selected. The selected papers were classified by continent and country, year of publication, occupation, classification criteria of workplace violence, and research topic. RESULTS: By country, the number of articles in the United States was the most with 40 (19.2%), followed by China 27 (13%), Korea 16 (7.7%), and Taiwan and Australia 15 (7.2%). By job category, healthcare workers accounted for the largest portion with 162 (79.0%) of the total, and 80 of them were conducted on nurses. Other occupations included civil servants, manufacturing workers, toll collectors and wageworkers. Among the classification methods of workplace violence, 147 (67.4%) articles were classified as type and there was a difference in the type of violence defined for each article. In the research topic, 114 (44.2%) articles analyzed the effects of workplace violence, and 105 (40.7%) articles describe the prevalence and characteristics of workplace violence, and 23 (8.9%) articles analyzing the causes of violence. CONCLUSION: The research topic is biased toward the field of healthcare, so it is necessary to expand to include various occupations or other specified occupations. It is also necessary to prepare appropriate measures against workplace violence.

The total number of scholarly publications grows day by day, making it necessary to explore and use simple yet effective ways to expose their metadata. Schema.org supports adding structured metadata to web pages via markup, making it easier for data providers but also for search engines to provide the right search results. Bioschemas is based on the standards of schema.org, providing new types, properties and guidelines for metadata, i.e., providing metadata profiles tailored to the Life Sciences domain. Here we present our proposed contribution to Bioschemas (from the project “Biotea”), which supports metadata contributions for scholarly publications via profiles and web components. Biotea comprises a semantic model to represent publications together with annotated elements recognized from the scientific text; our Biotea model has been mapped to schema.org following Bioschemas standards.

PURPOSE: The aim of this study was to review the common conditions associated with mandibular canal widening. MATERIALS AND METHODS: General search engines and specialized databases including Google Scholar, PubMed, PubMed Central, Science Direct, and Scopus were used to find relevant studies by using the following keywords: “mandibular canal,” “alveolar canal,” “inferior alveolar nerve canal,” “inferior dental canal,” “inferior mandibular canal,” “widening,” “enlargement,” “distension,” “expansion,” and “dilation.” RESULTS: In total, 130 articles were found, of which 80 were broadly relevant to the topic. We ultimately included 38 articles that were closely related to the topic of interest. When the data were compiled, the following 7 lesions were found to have a relationship with mandibular canal widening: non-Hodgkin lymphoma, osteosarcoma, schwannoma, neurofibroma, vascular malformation/hemangioma, multiple endocrine neoplasia syndromes, and perineural spreading or invasion. CONCLUSION: When clinicians encounter a lesion associated with mandibular canal widening, they should immediately consider these entities in the differential diagnosis. Doing so will help dentists make more accurate diagnoses and develop better treatment plans based on patients' radiographs.

PURPOSE: This study reviewed the common conditions associated with displacement of inferior alveolar nerve canal. MATERIALS AND METHODS: General search engines and specialized databases including Google Scholar, Pub Med, Pub Med Central, Science Direct, and Scopus were used to find relevant studies by using keywords such as “mandibular canal”, “alveolar canal”, “inferior alveolar nerve canal”, “inferior dental canal”, “inferior mandibular canal” and “displacement”. RESULTS: About 120 articles were found, of which approximately 70 were broadly relevant to the topic. We ultimately included 37 articles that were closely related to the topic of interest. When the data were compiled, the following 8 lesions were found to have a relationship with displacement of mandibular canal: radicular/residual cysts, dentigerous cyst, odontogenic keratocyst, aneurysmal bone cyst, ameloblastoma, central giant cell granuloma, fibrous dysplasis, and cementossifying fibroma. CONCLUSION: When clinicians encounter a lesion associated with displaced mandibular canal, they should first consider these entities in the differential diagnosis. This review would help dentists make more accurate diagnoses and develop better treatment plans according to patients' radiographs.

The Open Access Initiative is gaining momentum due to the worldwide availability of advanced digital tools, online publishing platforms, and systems for tracking academic contributions. Several declarations and initiatives, including Plan S, have already laid a foundation for moving away from subscription to full and immediate open-access publishing. The global initiatives imply targeting journals satisfying the upgraded quality and visibility criteria. To meet these criteria, a comprehensive approach to Open Access is recommended. This article overviews the essential components of the comprehensive approach, increasing transparency, adherence to ethical standards, and diversification of evaluation metrics. With the increasing volume of quality open-access journals, their indexing with free databases and search engines is becoming increasingly important. The Directory of Open Access Journals and PubMed Central currently free searches of open-access sources. These services, however, cannot fully satisfy the increasing demands of the users, and attempts are underway to upgrade the indexing and archiving of open-access sources in China, Japan, Korea, Russia, and elsewhere. The wide use of identifiers is essential for transparency of scholarly communications. Peer reviewers are now offered credits from Publons. These credits are transferrable to their Open Researcher and Contributor iDs. Various social media channels are increasingly used by scholars to comment on articles. All these comments are tracked by related metric systems, such as Altmetrics. Combined with traditional citation evaluations, the alternative metrics can help timely identify and promote publications influencing education, research, and practice.

PURPOSE: The purpose of this study was to review sexual abuse prevention education program for Korean elementary school students.METHODS: Whittemore and Knafl's integrative review methods were used and Gough's weight of evidence was employed as a quality appraisal tool. Articles published in Korean or English were identified through electronic search engines and scholarly web sites using three keywords: “elementary school student”, “sexual abuse”, and “prevention education”. Peer-reviewed articles published between 2000 and 2018 were included in this review.RESULTS: Twelve articles met the inclusion criteria and were appraised as being high-quality. Among the 12 selected studies, seven were descriptive, while five were intervention studies. Sexual abuse prevention education programs were effective in improving perceptions, knowledge, attitudes, and preventive behaviors among elementary school students. However, deficiencies were found in the variety of educational methods, utilization of experts, and standardization of the content of sexual abuse prevention education.CONCLUSION: We need to provide various educational methods that are appropriate for specific developmental stages, and the sexual abuse prevention content should draw upon the current sexual education program administered to this population. Furthermore, parents and trained teachers or school health teachers should be included to provide effective education programs for elementary students.

OBJECTIVE: The objective of the present study was to evaluate the effects of implementing a systematic Drug Utilization Review (DUR) system on contraindicated drug use and pharmaceutical expenditures in Korea. METHODS: A literature search was conducted using search engines such as PubMed, EMBASE, NDSL, and RISS for relevant systematic studies. The database search was performed and updated in April 2018. Two independent reviewers evaluated the abstracts to find potentially eligible articles. RESULTS: In total, 1433 potentially eligible studies were selected, and 11 articles were eventually shortlisted for inclusion in the present review system. The outcome showed that contraindicated drug use decreased after implementation of the DUR system in Korea. The analysis also showed that the DUR system contributed to a reduction in pharmaceutical expenditures. CONCLUSION: Our study showed that implementing the DUR system reduced both contraindicated drug use and pharmaceutical expenditures in Korea.

BACKGROUND: Work-related musculoskeletal disorders are the most important problems among professions particularly, dentists. This study was conducted to determine the prevalence of musculoskeletal disorders in various parts of the body in Iranian dentists by using systematic review and meta-analysis. METHODS: This systematic review and meta-analysis was based on preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines and searching in national databases such as SID, Magiran, Irandoc, IranMedex, and Medlib, and international databases such as MedLine,Web of Sciences, Scopus, PubMed, ScienceDirect, Cochrane, Embase, Springer, Wiley Online Library, Ebsco, CEBM, and Google Scholar search engine which were published by January 1, 2017. Researched keywords were in Persian and their standard English equivalents were in accordance with their MeSH. The obtained documents were analyzed using Comprehensive Meta-analysis version 2. RESULTS: According to 23 studies through 2,531 Iranian dentists which took part in this study, prevalence of skeletal disorders in Iranian dentists has been 17.6% [confidence interval (CI) 95%:11.7–25.5] in knees, 33.2% (CI 95%:24.1–43.8) in shoulders, 33.4% (CI 95%: 26.8–40.8) in the thorax, 51.9% (CI 95%:46.7–57.2) in necks, 33.7% (CI 95%:28.2–39.6) in wrists/hands, 12.9% (CI 95%:7.7–20.6) in elbows, 37.3% (CI 95%: 31.5–43.5) in lower back, 11.9% (CI 95%:8.7–16.1) in thighs, 12.9% (CI 95%:3.8–36) in the foot, and 10.5% (CI 95%:7–15.4) in legs. CONCLUSION: Considering the high prevalence of musculoskeletal disorders in Iranian dentists, ergonomics should be included as a lesson in preclinic and also, reeducation courses for ergonomics basics should be executed for graduate dentists.

BACKGROUND: Surgical and conservative methods have been reported by various studies for high rates of fracture union and subsequent regain of function among patients with undisplaced or minimally-displaced scaphoid fractures. Hence, this study aims to analyze the best available evidence to comprehend the relative benefits and risks of these therapeutic options. METHODS: A systematic search of the literature from different databases and search engines was performed with strict eligibility criteria to obtain the highest quality of evidence. All randomized controlled trials delineating the outcomes of surgical versus conservative treatments for acute undisplaced or minimally-displaced scaphoid fractures were included and then evaluated using scoring tools: Cochrane risk of bias tool and PEDro scale. Data were pooled using random-effects models with standard mean differences for continuous outcomes and risk ratios for dichotomous variables. RESULTS: The search yielded 339 potentially related articles, further trimmed down to eight studies based on the eligibility criteria. The meta-analysis revealed that surgical treatment resulted in significantly better functional outcomes than conservative treatment. Furthermore, surgery resulted in the prevention of delayed union of fractures and reduction of time needed to return to work. CONCLUSIONS: While four studies reported advantages of surgical treatment, evidence was insufficient to provide a definitive conclusion that surgery is a better option. Due to the significant limitations with respect to certain variables, the superiority of one method to the other could not be established.
