AbstractThe value of freight travel time savings (VFTTS) is a monetary value that is considered an important input into cost–benefit analysis and traffic forecasting. The VFTTS is defined as the marginal rate of substitution between travel time and cost and may therefore differ across firms, time and countries. The paper aims to explain variations in the VFTTS by using the meta-analysis method. The analysis covers 106 monetary valuations extracted from 56 studies conducted from 1988 to 2018 in countries across the globe. The meta-analysis method determines the factors that have an impact on these VFTTS variations. The paper briefly introduces the VFTTS concept and describes the adopted meta-analysis methodology, wherein different meta-models are used in VFTTS estimations. The results highlight the necessity of including multiple explanatory variables to ensure adequate explanation of the VFTTS variations. The findings also show that GDP per capita, transport mode and type of survey respondent are statistically significant variables. The paper sheds some light on the variations, thereby advancing the understanding of each factor’s effects on the VFTTS. Furthermore, meta-model outcomes are used to generate new values of travel time savings for different transport modes in freight transport, for several countries. These implied VFTTS can be used as benchmarks to assess existing evidence or provide new evidence to countries where no such values exist.

In this study, an analysis of independent studies dealing with occupational safety training in different learning environments, in which various learning materials are used, was carried out. As a method, meta-analysis method was used. For this purpose, databases were used to collect national and international articles and papers suitable for the purpose of the study. Studies that did not mention the tools, equipment and environment used in education in the collected studies were excluded from the research, and 18 studies were included in the meta-analysis. The data obtained studies are categorized according to the education models, the sectors in which the education is applied and the characteristics of the participants in the education. As it is known, occupational health and safety procedures aim at a healthy and reliable working environment for its employees. However, the ultimate goal is to raise not only employees but also future generations with this awareness. The most important instrument of this is undoubtedly education. For this reason, it is necessary to develop training models suitable for the work environment, age, gender and every conceivable situation.

This research aimed to analyze the types of media and the characteristics of physics materials that are suitable for use in the development of physics learning media, using Adobe Flash software. The research uses a meta-analysis method, which is a method for analyzing many of the research that has been done. This research uses secondary data obtained from previous research in the form of journals related to the media using Adobe Flash software for senior high school physics subjects. The journals examined in this research consisted of 20 research articles that developed an adobe flash-based interactive learning media for physics learning in senior high schools. The number of articles reviewed consisted of 3 articles from international journals and 17 articles from national journals. Based on the results of the analysis that has been done, found 13 physics materials obtained from 20 journals analyzed, where the concepts of temperature, heat, and transfer are the most widely used material as content in the development of physics learning media based on Adobe Flash software. While the type of media that is widely used in computer-based learning media.

The aim of this research is to examine articles and thesis studies in the field of authentic learning approaches and applications in education in the last 10 years and to reveal the trends in this context. In the methodology part of the research, the meta-analysis method was used. Meta-analysis studies refers to the critical review and integration of the findings of separate studies. For the purpose of the study, a total of 111 pieces of research, published between 2010 and 2021 and selected by purposeful sampling method were analyzed. Databases used in research are Eric, IEEE Xplore, Ebsco, Springer, Science Direct, Scopus, Web of Sciences. Authentic learning approaches and applications in education throughout the world were examined under 16 criteria. These data were interpreted based on percentage and frequency. As a result, authentic learning approaches and applicationare integrated in many fields such as ICT, engineering, network learning technology, nursing, curriculum & instruction, geography, medicine and more.   Keywords: Learning Approaches, Meta-Analysis, Publication Classification, Authenic, Analysis

The Relationship

Objective: The aim of this study was to identify the relationship between children's age and the incidence of unintentional injuries, and giving some basic data on the guidance for the prevention of unintentional injuries in children aged 0 to 18 years in China.Methods: The literatures on the incidence of unintentional injury in children included in China from 2008 to 2018 were analyzed by meta-analysis method. The data were retrieved according to the guidance of Cochrane Systematic review. A meta-analysis was carried out on homogeneous studies, and then subgroup analysis was conducted according to age group. Publication bias was also evaluated. Stata software (version 15.0) and SPSS software (version 18.0) were used to analyze the gathered information. Results: A total of 3，303 related pieces of literature were reviewed. Of the 37 that met the inclusion criteria. The meta-analysis showed that total sample sizes were 77，023, and the pooled incidence of unintentional injury is 20%, 95%CI (17%-23%), (P< 0.001). Subgroup analysis showed the following results: the incidence are 15%, 23%, 20% and 20% for aged in “0-2”, “3-5”, “6-11”, “12-18” subgroups, respectively. However, the trend of decreased incidence of unintentional injury with older age in children was not significant.Conclusions: The pooled incidence of unintentional injuries in children is high. Based on accessible literature, the incidence between different age subgroup were not statistically significant. We should pay attention to the incidence of unintentional injuries in children of all age subgroups.

Objective. To explore and define the current optimal submucosal injection solution used in ESD and EMR for gastrointestinal tract neoplasms in terms of clinical outcomes and other aspects.Methods. PubMed, Cochrane Library, Embase, and clinical trials register center were searched with terms of “endoscopic resection” and “submucosal injection solution” to identify relevant randomized controlled trials (RCTs). Both direct comparison using traditional meta-analysis method and indirect comparison using network meta-analysis method were performed.Results. A total of 11 RCTs with 1152 patients were included. Meta-analysis showed that, compared with normal saline, other submucosal injection solutions induced a significant increase in terms ofen blocresection rate(I2=0%, OR = 2.11, 95% CI (1.36, 3.26), andP= 0.008)and complete resection rate(I2=0%, OR = 2.14, 95% CI (1.41, 3.24), andP= 0.0003); and there was no significant difference in the incidence of total complications(I2=0%, OR = 0.87, 95% CI (0.59, 1.29), andP= 0.49).Conclusions. Other newly developed submucosal injection solutions significantly increaseden blocresection rate and complete resection rate and decreased bleeding rate and finical cost of endoscopic resection in gastrointestinal tract, while current evidence did not find the difference between them, which need to be explored by further studies.
