The assignment of cells to reporting or non-reporting cells is an NP-hard problem having an exponential complexity in the Reporting Cell Location Management (RCLM) system. Frequent location update may result in degradation of quality of service due to interference. Miss on the location of a mobile terminal will necessitate a search operation on the network when a call comes in. The number of reporting cells and which cell must be reporting cell should be determined to balance the registration (location update) and search (paging) operations to minimize the cost of RCLM system. T1is paper compares Max-Min ant system (MMAS), rank-based ant system (RAS) and hybrid method of MMAS and RAS that generally used to solve combinatorial optimization problems. Experimental results demonstrate that hybrid method of MMAS and RAS is an effective and competitive approach in fairly satisfactory results with respect to solution quality and execution time for the optimal design of location management system.

Objectives This systematic review aimed to analyze the effectiveness, safety and the reporting quality of scalp acupuncture (SA) treatment for musculoskeletal disease (MSD). Methods Eleven databases were systematically searched up to July 12th 2023. Randomized controlled trials (RCTs) of SA treatment for MSD were selected manually by the inclusion criteria. The risk of bias of RCTs was assessed using the Cochrane's Risk of Bias (RoB) 1.0 and the reporting quality of studies was evaluated using Consolidated Standards of Reporting Trials (CONSORT) 2010 statement and Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) 2010 checklist. Results Ten clinical studies were met the inclusion criteria. Most of studies reported SA treatment significantly alleviated pain and functional disability of MSD patients and no serious adverse effects were reported. In RoB assessment, blinding of participants and personnel was found to have the highest RoB and allocation concealment was found to have the most unclear RoB. In CONSORT 2010 statement evaluation, all studies reported 15.3 items (41.4%) on average. In STRICTA 2010 checklist evaluation, all studies reported 11.2 items (65.9%) on average. Conclusions The systematic review found that SA treatment may alleviate pain and functional disability of MSD patients and have little severe adverse effect. The reporting quality of included studies was mainly low, therefore, further studies with strict adherence to the CONSORT and STRICTA checklist should be encouraged.

Recently, there are lots methodologies to improve the quality of research in medical and public health fields. One of them is to checking a process of research with a reporting guideline before reporting paper. Especially, reporting guideline for randomized controlled trials (RCTs) is the consolidated standards of reporting trials (CONSORT). Therefore, this review describes the latest version of the CONSORT statement, CONSORT 2010, including intent, background, and contents of this. The CONSORT statement comprises a checklist of essential items that should be included in reports of RCTs and a diagram for documenting the flow of participants through a trial. This report guideline aims at providing guidance to authors about how to improve the reporting of their trials. As consulting the CONSORT, authors could be strictly reported about research methods and results. From this review, we expect to elevate the quality of such research about dental hygiene and to establish the foundation for evidence-based dental hygiene.

Purpose: The objective of this study was to publicly report the hospital-level surgical volume for 7 types of surgery including gastrectomy. Also, to investigate the changes in patient behaviors after the public reporting among patients with gastrectomy. Methods: This study used data from the National Health Insurance Service Cohort. The data comprised of 2,214 patients who were diagnosed with gastric cancer and underwent gastrectomy during 2004-2012. An interrupted time series analysis was performed to investigate the association between patients' choice and public reporting. Results: 79.27% of the patients visited a hospital with high surgical volume. The time trend after introduction of public reporting was positively associated with visiting a high volume hospital (per 1 month, RR: 1.004, p=0.0329). However, after adjusting the health policies by reducing copayment, public reporting on surgical volume was not associated with visiting a high volume hospital. Sub-group analyses had also similar results. Conclusion: Patients were more affected by policies on economic support than on public reporting, and the changes in treatment options may have been affected by the increasing preference for large size hospitals. Thus, public reporting did not significantly improve the options available for patients and their decision making on health care utilization.

Objective: To evaluate the completeness of the reporting of systematic reviews and meta-analyses published in a general radiology journal using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Materials and Methods: Twenty-four articles (systematic review and meta-analysis, n = 18; systematic review only, n = 6) published between August 2009 and September 2021 in the Korean Journal of Radiology were analyzed. Completeness of the reporting of main texts and abstracts were evaluated using the PRISMA 2020 statement. For each item in the statement, the proportion of studies that met the guidelines' recommendation was calculated and items that were satisfied by fewer than 80% of the studies were identified. The review process was conducted by two independent reviewers. Results: Of the 42 items (including sub-items) in the PRISMA 2020 statement for main text, 24 were satisfied by fewer than 80% of the included articles. The 24 items were grouped into eight domains: 1) assessment of the eligibility of potential articles, 2) assessment of the risk of bias, 3) synthesis of results, 4) additional analysis of study heterogeneity, 5) assessment of non-reporting bias, 6) assessment of the certainty of evidence, 7) provision of limitations of the study, and 8) additional information, such as protocol registration. Of the 12 items in the abstract checklists, eight were incorporated in fewer than 80% of the included publications. Conclusion: Several items included in the PRISMA 2020 checklist were overlooked in systematic review and meta-analysis articles published in the Korean Journal of Radiology. Based on these results, we suggest a double-check list for improving the quality of systematic reviews and meta-analyses. Authors and reviewers should familiarize themselves with the PRISMA 2020 statement and check whether the recommended items are fully satisfied prior to publication.

This study examines the effect of board structure and audit committee structure on financial reporting timeliness among Malaysia's top 100 public listed companies. Specifically, this study examines whether board independence, CEO duality, board ownership, audit committee independence, audit committee competence, and audit committee diligence influence the financial reporting timeliness of the public listed companies. This study selects the top 100 public listed companies by market capitalization listed on the Main Market of Bursa Malaysia as the sample since the main board has more public reprimands on financial reporting timeliness compared to other boards. The content analysis on annual reports for five years from 2015 to 2019 is utilized. The results show that audit committee competence and audit committee diligence significantly affect financial reporting timeliness. In contrast, board independence, CEO duality, board ownership, and audit committee independence have insignificant relationships with financial reporting timeliness. The findings in this study are helpful for compliance analysis and strategy formation in enhancing financial reporting timeliness. This study contributes to the agency theory by providing a new perspective on how different sections of corporate governance features interact together to influence financial reporting timeliness. In addition, the findings can assist the regulators in establishing quality corporate governance.

The purpose of this study was to assess the quality of the case reports in the Journal of Acupuncture Research (JAR). All case reports were retrieved from November 2017 to June 2020. There were 19 case reports included in this assessment based on the case report (CARE) guidelines and case report and standards for reporting interventions in clinical trials of acupuncture (STRICTA) guidelines. The overall quality of reporting was relatively high (83.08% on Case Report guidelines and 77.78% on Standards for Reporting Interventions in Clinical Trials of Acupuncture guidelines), but several crucial items remained substantially underreported, such as identifying as a case report (keywords), patient information and perspective, clinical findings, diagnostic assessment, and intervention information. In 18 out of 19 included case reports of acupuncture-related interventions, several items remained considerably underreported such as acupuncture regimen variation, depth of needle insertion, response sought, and experience of acupuncturists. In the classification by disease, condition, or syndrome, 13 out of 19 included case reports were for musculoskeletal disorders (68.4%), which is the main clinical medical field of Korean medicine services. The results of this study may help develop more appropriate reporting guidelines for case reports published in JAR.

Purpose: This study was done to evaluate quality of reports of non-randomized controlled quasi-experimental study articles published in the Korean Journal of Women Health Nursing (KJWHN). Methods: A search was done for experimental studies assessing intervention effects among all articles published in the KJWHN from 2008 to 2013. Original articles were reviewed and analyzed according to the 22 checklist items of the guidelines for Transparent Reporting for Evaluations with Non-randomized Designs (TREND). Results: Thirty-five articles on experimental studies were identified. The evaluation of the quality of reporting in these experimental studies found that there was a wide variety in the level of satisfying the TREND checklist. In particular, according to TREND topics, low levels of reporting quality were found for "title & abstract (only for information on how units were allocated to the intervention)", "outcomes in methods", "assignment in methods", "blinding in methods", "recruitment in results", "baseline data in results", "interpretation in discussion (especially intervention mechanism and success or barriers), "generalizability in discussion". Conclusion: Results indicate that adherence to TREND guidelines varied in experimental studies published in the KJWHN suggesting the recommendation that for higher levels of complete reporting, TREND guidelines be used in reports on experimental studies.

Objectives: The purpose of this study is to assess the quality of case reports from the Journal of Obstetrics and Gynecology of Korean Medicine. Methods: Case reports were selected from the Obstetrics and Gynecology of Korean Medicine from January 2015 to March 2019, by utilizing Oriental Medicine Advanced Searching Integrated System (OASIS). The quality of the reports were reviewed based on the Consensus-based Clinical Case Reporting Guideline Development (CARE) guideline. Results: Total of 41 case reports were finally selected for the assessment. 69.23% of the case reports included necessary information based on the CARE guideline but the rest of the reports did not. More than 50% of the reports were missing data regarding 'Diagnostic challenges', 'Intervention adherence and tolerability', 'Adverse and unanticipated events', or 'Patient perspective or experience', and 'Informed consent'. Also, the reports did not include 'Key word', 'timeline'. Conclusions: Case reports from the Journal of Obstetrics and Gynecology of Korean Medicine have important role in women. Efforts are needed to improve the quality of the case reports as well as to develop reporting guidelines for the Journal of Obstetrics and Gynecology of Korean Medicine.
