Research on Constructing Cheerleading Sport Education Model (CSEM) by Delphi Method

Based on the components of the physical education teaching model, this study combined the cheerleading and Sport Education Model (SEM) to develop the Cheerleading Sport Education Model (CSEM), which aims to construct a new cheerleading teaching model at China University. It adopted the Delphi method and invited 10 experts as the research objects to conduct three rounds of questionnaires. Delphi technology is a widely used and accepted method to gain consensus among experts. In the first round, the experts who participated in the survey received a questionnaire about the components of CSEM and evaluated whether each component should be retained or deleted according to the median and Quartile Difference (QD). In the second round, experts re-evaluated the components by experts and finally adjusted the contents of the text modification opinions put forward by experts. In the third round, experts re-evaluated the newly proposed components. Participants were asked to rate the categorized responses from Round 1 on a scale of 1 to 5, with 1 being “Very Irrelevant” and 5 being “Very Relevant”. Based on three rounds of Delphi data analysis, the results show that all the items that reach QD ≤0.5 and M ≥4 remain the final components of CSEM. The important results of this study are as follows: 4 primary indexes and 19 secondary indexes are constructed as the components of CSEM. This important research result will lay a theoretical foundation for the future application research of the CSEM teaching model.

In the question of “how to improve the existing problems in the management of Taekwondo in China” and the opinion of taekwondo leaders, it is necessary to draw up a safety operation plan to ensure adequate response to the Pandemic situation in the future.

A hybrid SEM-ANN model for predicting overall rework impact on the performance of bridge construction projects

Determining the factors that cause rework in bridge is necessary to assess the impact of rework on a cost, which have been increasing in recent times. This research aims to evaluate the impact of rework on cost. In contrast to prior rework research, which focused heavily on structural equation modelling (SEM) analysis; this study uses a hybrid learning analytic approach based on the acceptance of a hybrid approach where the outputs of the second-order structural equation model are used as inputs to the artificial neural network, which derived from deep learning. Through the means of a questionnaire survey, 260 experts have participated in the study. The findings indicated that all rework factors have significant positive impacts on cost. There were 33 reasons for rework that affect the project performance. Using Delphi technology, these variables were reduced to 27. The final SEM model adapts 21 factors across five groups for reworking reasons. Wherein, the initial model RMSEA was 0.071, it became 0.057 in the final SEM model. The proposed hybrid model supports the relevance of the construction process-related factors in reducing rework on the bridge project. In comparison to the predicted value of the rework calculated by the hybrid model, the error rate was within 10 %. In practise, the findings will allow decision-makers and practitioners on construction sites to determine which aspects should be prioritised above others and design their policies appropriately. Methodologically, this study determines the deep ANN architecture's capabilities in finding non-linear correlations among the elements in the theoretical model.

The rationale for dislocation of interregional specialized surgical care centers for children in the Russian Federation

Introduction. In Russia, there is a need to reorganize the system of providing specialized surgical care to children, primarily in emergency and urgent care and in remote, sparsely populated, and hard-to-reach areas. This need is evidenced by the significant persisting disparities in the mortality rate in the countrys various regions.
 Purpose of the study. This study aims to provide multifactorial substantiation of the expediency, profile, and location of specialized (surgical) interregional centers (MRC), including high-tech, medical care for children, by the priority profiles of activity, about medical organizations of the federal districts (FD) of Russia.
 Materials and methods. The study design included a two-level (regional and federal) system of professional expertise and justification in terms of the profile, location, and area of responsibility of the MRC in the federal district of the country. At the regional level, Delphi technology was implemented with a mathematical and statistical analysis of 103 expert opinions from 85 constituent entities of Russia, the result of which activities priority profiles were substantiated (newborn surgery, neurosurgery, thoracic surgery, oncology, combustiology) and patient routing preferences. At the second stage of the work, with the involvement of federal experts, the SWOT analysis technology was implemented as a universal method of strategic planning, with the justification of the location and number of MRCs in individual FD of the country, about specific medical organizations where they are based. For an objective (quantitative) assessment of the provision of the Federal District of Russia with the MRC of specialized medical care for children according to the established profiles of activity, we have proposed a calculated indicator the regional contingency coefficient (CRC), representing the ratio of two uniformly calculated values the number of MRCs and regions in a particular Federal District, or the country as a whole.
 Results. The consolidated position of federal experts regarding the location of the MRC was formulated according to the established profiles of activity about FD and specific medical organizations in the Russian Federation constituent entities. The cattle in the profile of the activity of neonatal surgery was 0.14, and about neurosurgery, thoracic surgery, and oncology, respectively, 0.12, 0.11, and 0.11 for Russia as a whole. The lowest (0.09) cattle in the country characterized the situation with the combustiology profile. In the overwhelming majority (76.0%), the location of the MRC is tied to the administrative centers of the Federal District or cities of federal significance. Among the 50 MRCs of all priority profiles, 43 (86%) were potentially designated by experts based on multidisciplinary pediatric medical organizations.
 Discussion. The effectiveness of the MRC functioning is due to the organization of medical and evacuation support for children with diseases and injuries. The development of consultative and resuscitation centers in the primary hospital structure is promising. Its functionality, along with remote counseling, treatment, and evacuation activities, includes monitoring the condition of sick and affected children at the place of primary hospitalization. An alternative is a presence on the clinical base of the MRC of a structural unit or a branch of the regional center for emergency medical care and disaster medicine.
 Conclusion. Overcoming the inequality in the availability and quality of medical care for children in certain FD and regions of Russia is necessary to reorganize the current system of staged medical care. Optimal logistics of medical and evacuation support for specialized patients and injured people include the MRC as a collector for children in need of specialized care, including high-tech medical care, with the implementation of the predominant principle of evacuation of oneself.

Construction of Evaluation Indexes for the Integrated Development of Leisure Agriculture Management: The Application of Delphi Technology

Leisure agriculture is a new industry that applies agricultural resources to leisure and recreational activities to meet the needs of tourists, increase farmers’ income, and then increase the value of agriculture. The purpose of this research is to develop structured evaluation indicators to analyze the comprehensive development of leisure agricultural management, and becomes a business model that can be quantitatively replicated. The study after screening by the Delphi Method, the five evaluation aspects of “corporate organization operation”, “leisure agricultural resources”, “maintenance of the operating environment”, “maintenance of surrounding facilities” and “operating performance” and 21 evaluation criteria are established. The research results show that leisure agriculture enterprises can be used as the evaluation aspect and evaluation criteria for leisure agricultural operations. Besides, according to the technical analysis of Delphi method, leisure agricultural operations should pay attention to the smoothness of internal operations and key processes of the enterprise organization, and strive to integrate resources inside and outside the enterprise. Only with the concept of integrated development can we create sustainable management of leisure business.

The results of this questionnaire study provided a basis for the pilot consensus document and allowed for the preliminary conclusion as regards prospects for the further exploration of both the problem in question and the instruments for this purpose with special reference to the awareness of the otorhinolaryngologists.

A Delphi Technology Foresight Study: Mapping Social Construction of Scientific Evidence on Metagenomics Tests for Water Safety.

Access to clean water is a grand challenge in the 21st century. Water safety testing for pathogens currently depends on surrogate measures such as fecal indicator bacteria (e.g., E. coli). Metagenomics concerns high-throughput, culture-independent, unbiased shotgun sequencing of DNA from environmental samples that might transform water safety by detecting waterborne pathogens directly instead of their surrogates. Yet emerging innovations such as metagenomics are often fiercely contested. Innovations are subject to shaping/construction not only by technology but also social systems/values in which they are embedded, such as experts’ attitudes towards new scientific evidence. We conducted a classic three-round Delphi survey, comprised of 107 questions. A multidisciplinary expert panel (n = 24) representing the continuum of discovery scientists and policymakers evaluated the emergence of metagenomics tests. To the best of our knowledge, we report here the first Delphi foresight study of experts’ attitudes on (1) the top 10 priority evidentiary criteria for adoption of metagenomics tests for water safety, (2) the specific issues critical to governance of metagenomics innovation trajectory where there is consensus or dissensus among experts, (3) the anticipated time lapse from discovery to practice of metagenomics tests, and (4) the role and timing of public engagement in development of metagenomics tests. The ability of a test to distinguish between harmful and benign waterborne organisms, analytical/clinical sensitivity, and reproducibility were the top three evidentiary criteria for adoption of metagenomics. Experts agree that metagenomic testing will provide novel information but there is dissensus on whether metagenomics will replace the current water safety testing methods or impact the public health end points (e.g., reduction in boil water advisories). Interestingly, experts view the publics relevant in a “downstream capacity” for adoption of metagenomics rather than a co-productionist role at the “upstream” scientific design stage of metagenomics tests. In summary, these findings offer strategic foresight to govern metagenomics innovations symmetrically: by identifying areas where acceleration (e.g., consensus areas) and deceleration/reconsideration (e.g., dissensus areas) of the innovation trajectory might be warranted. Additionally, we show how scientific evidence is subject to potential social construction by experts’ value systems and the need for greater upstream public engagement on metagenomics innovations.

A Delphi technology forecasting approach using a semi-Markov concept

This paper suggests a technology forecasting approach based on a semi-Markov model, which appropriately describes the probabilistic nature of a sequential technology development process. This approach focuses primarily on the utilization of the information that has been skipped in conventional Delphi survey data. That is, through a simple statistic, the interrelationships among sequential technology developments can be extracted in a formal structure of a semi-Markov model from the original Delphi panel's estimates. A simulation technique is developed to forecast the development process by utilizing the information on such interrelationships. This technique provides a flexible and useful tool for R&D planners or project managers, especially in postanalysis of Delphi forecasting. To make good use of the approach, a computer-based interactive Delphi data analysis system (IDEAS) is implemented in IBM PC.
