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: Workplace violence (WPV) against healthcare workers (HCWs) employed in psychiatric inpatient wards is a serious occupational issue that involves both staff and patients; the consequences of WPV may include increased service costs and lower standards of care. The purpose of this review was to evaluate which topics have been focused on in the literature and which are new in approaching the concern of patient violence against HCWs employed in psychiatric inpatient wards, in the past 20 years. Methods: We searched for publications in PubMed and Web of Science using selected keywords. Each article was reviewed and categorized into one or more of the following four categories based on its subject matter: risk assessment, risk management, occurrence rates, and physical/nonphysical consequences. Results: Our search resulted in a total of 64 publications that matched our inclusion criteria. The topics discussed, in order of frequency (from highest to lowest), were as follows: "risk assessment," "risk management," "occurrence rates," and "physical/nonphysical consequences." Schizophrenia, young age, alcohol use, drug misuse, a history of violence, and hostile-dominant interpersonal styles were found to be the predictors of patients' violence. Conclusion: Risk assessment of violence by patients appeared the way to effectively minimize the occurrence of WPV and, consequently, to better protect mental HCWs. We found paucity of data regarding psychologic sequelae of WPV. According to these findings, we suggest the need to better investigate the psychologic consequences of WPV, with the aim of checking the effective interventions to assist HCW victims of violence and to prevent psychologic illness.

The information of eye movement is used in various fields such as psychology, ophthalmology, physiology, rehabilitation medicine, web design, HMI(human-machine interface), and so on. Various devices to detect the eye movement have been developed but they are too expensive. The general methods of eye movement tracking are EOG(electro-oculograph), Purkinje image tracker, scleral search coil technique, and video-oculograph(VOG). The purpose of this study is to embody the algorithm which tracks the location of the gazing point at a pupil. Two kinds of location data were compared to track the gazing point. One is the reference points(infrared LEDs) which is effected from the globe. Another is the center point of the pupil which is gained with a CCD camera. The reference point was captured with the CCD camera and infrared lights which were not recognized by human eyes. Both of images which were thrown and were not thrown an infrared light on the globe were captured and saved. The reflected reference points were detected with the brightness difference between the two saved images. In conclusion, the circumcenter theory of a triangle was used to look for the center of the pupil. The location of the gazing point was relatively indicated with the each center of the pupil and the reference point.

It's getting popularized to collect information connecting web sites with massive information through the internet and advanced search engines. Users can handle digital materials like E-book wherever the internet is available and they will demand digital information increasingly. This study analyzes literature investigation, statistics analyses of the attached library of Kyushu University, drawings and field investigation to suggest a new model of a library which handles traditional paper-formed materials and digital-formed materials at one place with growing importance of digital materials. It results that a library performs a important role like a learning space and functions as a sociocultural communication space. Also it shows that it is required to basically reinvestigate the role of 'space' in the library with a great importance of digital materials. In the hybrid library combined with subjects and reorganized at one place, One-stop services like library materials and manpower can be provided for users staying at the same area.

Recent commencement of digital broadcasting has enabled various TV programs through hundreds of channels. As a result, it becomes a time-consuming job for the TV audience to look up newspaper or TV magazines for the schedule of a specific TV program. To relieve this problem, digital broadcasting usually provides an EPG(Electronic Program Guide) for the audience. Currently. most EPG services are focusing on the visual delivery of information through a web site, digital TV or mobile devices. However, this approach could cause a serious restriction to some users including drivers or visually handicapped persons, who can't input keywords for the search. In order to solve this problem, in this paper, we propose a VoiceXML-based EPG retrieval system that enables even such special users to browse EPG. conveniently using a mobile phone. We implemented a prototype system and proved its effectiveness through experiments.

Background: Cancer screening rates are lower in Japan than those in western countries. Health professionals publish procancer screening messages on the internet to encourage audiences to undergo cancer screening. However, the information provided is often difficult to read for lay persons. Further, anti-cancer screening activists warn against cancer screening with messages on the Internet. We aimed to assess and compare the readability of pro- and anti-cancer screening online messages in Japan using a measure of readability. Methods: We conducted web searches at the beginning of September 2016 using two major Japanese search engines (Google.jp and Yahoo!.jp). The included websites were classified as "anti", "pro", or "neutral" depending on the claims, and "health professional" or "non-health professional" depending on the writers. Readability was determined using a validated measure of Japanese readability. Statistical analysis was conducted using two-way ANOVA. Results: In the total 159 websites analyzed, anti-cancer screening online messages were generally easier to read than pro-cancer screening online messages, Messages written by health professionals were more difficult to read than those written by non-health professionals. Claim ${\times}$ writer interaction was not significant. Conclusion: When health professionals prepare pro-cancer screening materials for publication online, we recommend they check for readability using readability assessment tools and improve text for easy comprehension when necessary.

The study aims to examine how exposure to phonography on the internet affects adolescents' behaviour toward sexual assault and the sex trade industry based on the social learning theory. A nationwide survey was conducted on adolescents between the ages of 14 to 19. Responses from a total of 2,829 adolescents were obtained and utilized in the analysis. The analytic findings showed that Korean adolescents are heavily exposed to phonography on the internet. Students use the internet to search for pornographic web sites, and they periodically look for updated materials. The study showed that between 1.8% to 16.5% of adolescents, who were exposed to or watched pornographic materials, committed sexual assault and were guilty of sexually harassing others. 3.5%(95) of those who were surveyed experienced sex trade. Internet chat rooms are considered to be a contributing factor. The results show that adolescents who were exposed to phonography are more prone to committing the acts of sexual assault and sexual harrassment, and tend to be more influenced toward sexual violence.

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.

Purpose: MicroRNAs (miRNAs) are epigenetic post-transcriptional regulators that modulate gene expression and have been identified as biomarkers for several diseases, including cancer. This study aimed to systematically review the relationship between miRNAs and periodontal disease in humans, and to evaluate the potential of miRNAs as diagnostic and prognostic biomarkers of disease. Methods: The review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines (reference number CRD42020180683). The MEDLINE, Scopus, Cochrane Library, Embase, Web of Science, and SciELO databases were searched for clinical studies conducted in humans investigating periodontal diseases and miRNAs. Expression levels of miRNAs across the different groups were analysed using the collected data. Results: A total of 1,299 references were identified in the initial literature search, and 23 articles were finally included in the review. The study designs were heterogeneous, which prevented a meta-analysis of the data. Most of the studies compared miRNA expression levels between patients with periodontitis and healthy controls. The most widely researched miRNA in periodontal diseases was miR-146a. Most studies reported higher expression levels of miR-146a in patients with periodontitis than in healthy controls. In addition, many studies also focused on identifying target genes of the differentially expressed miRNAs that were significantly related to periodontal inflammation. Conclusions: The results of the studies that we analysed are promising, but diagnostic tests are needed to confirm the use of miRNAs as biomarkers to monitor and aid in the early diagnosis of periodontitis in clinical practice.

Objectives The purpose of this thesis is to compare and analyze outcomes of case studies and controlled studies about Hwangryunhaedok-tang (HHT) pharmacopuncture in clinical studies. Based on these studies reporting clinical effects by using HHT pharmacopuncture, we object to deduct the comparative review in applying clinical disorders limitedly. And conclusionally, by using this comparative review, we aim to make the fine evidence in treating clinical specific diseases. Methods We searched 106 studies about HHT pharmacopuncture from 6 Korean web databases by using in Korean word 'Hwangryunhaedok-tang pharmacopuncture'. This search had been progressed throughout 1 month (January, 2019). There was 106 thesis and we excluded studies that are not related to HHT pharmacopuncture, experimental research, not the case report or randomized controlled trials, non-randomized controlled trials, not using HHT pharmacopuncture, not using only one pharmacopuncture, and not using HHT pharmacopuncture for major treating method. As a result, 39 thesis are selected as a population. Results We analyzed 34 case reports and 5 controlled studies. As the final outcome, HHT pharmacopuncture was used in musculoskeletal diseases, dermatopathy, and 32 specific diseases. Conclusions After analyzing 39 studies, effective symptom changes clinically and statistically by using HHT pharmacopuncture herbal acupuncture were identified. However, these thesis designs were reported deficiently in many parts such as not excluding other confounding variables. After modifying defects of thesis design and conduct study, it can play a role as the evidence using HHT pharmacopuncture more precisely.
