Background and Objective: A comprehensive overall review of gastric cancer (GC) risk and protective factors is a high priority, so we conducted the present study. Methods: Systematic searches in common medical electronic databases along with reference tracking were conducted to include all kinds of systematic reviews (SRs) about GC risk and protective factors. Two authors independently selected studies, extracted data, and evaluated the methodological qualities and the quality of evidence using R-AMSTAR and GRADE approaches. Results: Beta-carotene below 20 mg/day, fruit, vegetables, non-fermented soy-foods, whole-grain, and dairy product were GC protective factors, while beta-carotene 20 mg/day or above, pickled vegetables, fermented soy-foods, processed meat 30g/d or above, or salty foods, exposure to alcohol or smoking, occupational exposure to Pb, overweight and obesity, helicobacter pylori infection were GC risk factors. So we suggested screening and treating H. pylori infection, limiting the amount of food containing risk factors (processed meat consumption, beta-carotene, pickled vegetables, fermented soy-foods, salty foods, alcohol), stopping smoking, avoiding excessive weight gain, avoidance of Pb, and increasing the quantity of food containing protective components (fresh fruit and vegetables, non-fermented soy-foods, whole-grain, dairy products). Conclusions: The conclusions and recommendations of our study were limited by including SRs with poor methodological bases and low quality of evidence, so that more research applying checklists about assessing the methodological qualities and reporting are needed for the future.

Objectives This systematic review aimed to analyze research about pelvic deviation diagnosis for Chuna manual therapy (CMT) and to review the diagnosis methods, indices, and results of diagnosis. Methods Ten electronic databases were systematically searched up to January 4th 2022. Clinical studies and reviews containing pelvic deviation diagnosis for CMT or using CMT as a treatment of pelvic deviation were selected and evaluated. CMT diagnosis in clinical studies and reviews were isolated and analyzed by 2 independent reviewers. Results Thirteen clinical studies and three reviews were included in the evaluation. X-ray analysis and manual testing were the two main methods used in CMT diagnosis of pelvic deviation. For manual testing in clinical studies, leg length insufficiency testing was the most frequently used measurement index and the most common diagnostic results were anterior and posterior rotation. In the X-ray analysis, Obturator foramen and femur head line were the most frequently used measurement index and the most common diagnostic results were anterior rotation and posterior rotation. Conclusions The systematic review found that manual testing and X-ray analysis were mainly used for the diagnosis of pelvic deviation in CMT among clincial and review articles. As there was little research about diagnosing pelvic deviation in CMT and any existing research presented only low standards of evidence, further research should be updated with using a more standardized approach.

Among the customer-oriented data used to comprehend the customer, the user review data has received much attention as it provides insights into customer opinion in a detailed and large-scale manner; many customers have come to rely upon and trust the user reviews. Many application developers are cognizant of the importance of user reviews, so they monitor and respond to these reviews. However, due to the absence of a systematic method, developers have been investing their time and money without clear correlation to the customer satisfaction. Therefore, this paper suggests a systematic method to select user reviews from the application market using the Kano Model that deals with customer satisfaction and service quality, thereby maximizing the customer satisfaction under the given time period and budget. This method is constructed in the following phases: the user review collection and requirement elicitation phase in which the developers collect user reviews from the application market and elicit requirements, the Kano Model application and selection phase in which the Kano Model is applied to the elicited requirements and selection occurs based on the quality type, and the stakeholder review and redefinition phase in which relevant personnel gather to review and redefine requirements from an internal perspective.

Purpose: The purpose of the study was to assess the quality of meta-analyses on nursing published in South Korea. Methods: Relevant meta-analyses were identified through searches of the National Assembly Library, KISS (Korean Studies Information Service System), and the DBpia and RISS4U databases from 1990 to May 2013. Quality assessments were conducted using AMSTAR, a validated tool for assessing the quality of systematic reviews. Results: Forty-two meta-analyses were included in this study. Twenty-nine published between 1990 and 2010, and 13, between 2011 and May 2013. Two high quality studies and 11 moderate quality studies were published in the latter period. The mean score for the reviews was 5.61 (range 3-10); 11 studies were rated as low quality, 29 as moderate quality, and two as high quality. Conclusion: Although an improvement in the quality of meta-analyses conducted by nursing researchers in South Korea was observed across the study period, the study results indicate a need to use of more rigorous research methods when conducting systematic reviews or meta-analyses.

Construction designs are often produced with insufficient considerations on the constructability aspects. Poor constructability has resulted in delay, cost increase, disputes, safety hazards and inconvenience to the public. Increasingly, there has been a call for more systematic input of construction knowledge in the planning and design processes of modern day's infrastructure development. In some countries, notably the US, the practice of constructability reviews is on the rise, with concomitant benefits. It is advocated that construction plans and designs be subject to constructability reviews as early as possible. It should be made part of the project management strategy driven by the client. This paper outlines the constructability review process and benefits, whilst drawing lessons from a number of case studies.

Objectives: The purpose of this overview was to summarize the evidence regarding the effectiveness of Cognitive Behavioral Therapy (CBT) for sleep disorders through systematic reviews (SRs) and meta-analyses (MAs). Methods: An overview of systematic review was conducted according to the study protocol (reviewregistry1320). A comprehensive literature search was performed using three databases (Pubmed, Cochrane Central Register of Controlled Trials, and Web of Science) and three Korean databases (KoreaMed, KMbase, and ScienceON). Final studies were selected by three authors according to inclusion and exclusion criteria, and data needed for analysis were extracted by a pre-planned extraction framework. Methodological quality of systematic review was assessed using the 'Assessment of multiple systematic reviews 2 (AMSTAR2)'. Results: Fourteen SRs and MAs were included, of which eleven SRs were performed MAs. Twelve studies studied insomnia among sleep disorders, and the rest are nightmares and sleep disturbances with PTSD. Ten studies reported the effect of CBT on sleep disorders measured by insomnia severity index (ISI) and sleep onset latency (SOL), and all reported a significant improvement effect. Eight studies reported the effect of CBT on sleep disorders measured by wake time after sleep onset (WASO), and seven studies reported a significant improvement effect. The methodological quality of the studies evaluated with AMSTAR 2 was mainly low or very low because of omission of protocol registration and excluded study list. Conclusions: Practical guidelines and studies show that CBT is effective for sleep disorders, but access to CBT needs to be improved.

Objectives This study amied to assess the reporting quality of systematic reviews(SRs) in the Journal of Chuna Manual Medicine for Spine & Nerves (JCMM). Methods SRs in JCMM from January 2000 to June 2023 were selected using the Research Information Sharing Service(RISS) and JCMM homepage. Two independent researchers reviewed SRs and evaluated their reporting quality using AMSTAR 2. Results A total of 51 SRs were included for assessment. The evaluation revealed 21 studies as having critically low quality, and 30 as having low quality the reporting of items in the studies ranged from a maximum of 81.2% to a minimum of 56.3%. On average, SRs reported 11.1 out of the total 16 items for AMSTAR 2 reporting quality. Conclusions To improve the quality of SRs published in JCMM, it is recommended to conduct SRs based on AMSTAR 2 and adhere to PRISMA 2020 guidelines.

Objectives: We performed a systematic review to assess and aggregate the available evidence on the frequency, expected effects, obstacles, and facilitators of disclosure of patient safety incidents (DPSI). Methods: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for this systematic review and searched PubMed, Scopus, and the Cochrane Library for English articles published between 1990 and 2014. Two authors independently conducted the title screening and abstract review. Ninety-nine articles were selected for full-text reviews. One author extracted the data and another verified them. Results: There was considerable variation in the reported frequency of DPSI among medical professionals. The main expected effects of DPSI were decreased intention of the general public to file medical lawsuits and punish medical professionals, increased credibility of medical professionals, increased intention of patients to revisit and recommend physicians or hospitals, higher ratings of quality of care, and alleviation of feelings of guilt among medical professionals. The obstacles to DPSI were fear of medical lawsuits and punishment, fear of a damaged professional reputation among colleagues and patients, diminished patient trust, the complexity of the situation, and the absence of a patient safety culture. However, the factors facilitating DPSI included the creation of a safe environment for reporting patient safety incidents, as well as guidelines and education for DPSI. Conclusions: The reported frequency of the experience of the general public with DPSI was somewhat lower than the reported frequency of DPSI among medical professionals. Although we identified various expected effects of DPSI, more empirical evidence from real cases is required.

The purpose of this study is to identify trends in the type and method of Inertial Measurement Unit (IMU) by investigating studies on the type and method of convergence study of the IMU by systematic review. The study was conducted using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. 23 studies that meet the selection criteria were selected from 630 studies identified by three databases. As a result of this study, showed that various research using IMU was being conducted around the world, and the type of IMU was strap, full body suit, belt, wrist watch, shoes and glove. Among them, the number of strap-type IMUs was the largest at 11. The IMU's strengths were simplicity, real-time data collection and ease of application, which were used as measurement methods such as task, walking, and range of joint. The result of this study is expected to be used as basic data for experts in the medical and rehabilitation fields that conduct IMU research.
