The Evaluation System

With the development of modern society, the competition in all fields is becoming increasingly intensified. Therefore, people must be strong in volition if they want to stand out in such a competitive society. Especially for college students, they should form strong volition with the help of school education, or it will be difficult for them to make a career in the future. The research on college students’ ability to develop the physical exercising habit and volition is vital to the physical education of college students. This paper researches on the feasibility of developing college students’ ability to form volition by developing their physical exercising habit through school education, and analyses the influence factors of the formation of volition, hoping to give some theoretical references to the evaluation system of the ability to develop the physical exercising habit and volition.

With the ideality of sustainable development, this paper summarizes the meaning, principles and characteristics of the evaluation green university index system by probing into the research about the present construction of green university and related field. The system is based on a tree-like structure that consists respectively of the overall goal and multilevel indices. The thesis put forward an index system for assessment of green university, which contains five aspects (the green concept, the green culture, the green research, the green education, the green campus). Afterwards, the weightiness of index is determined by the way of AHP, and the method of the multi-hierarchy comprehensive evaluation system is applied to evaluate the universitys green degree.

The typical high temperature environment of the mine, using single index evaluation system has been unable to meet the requirements of mine thermal environment of high temperature. Through the analysis of thermal equilibrium conditions affecting the thermal comfort of the mine workers of various factors and human thermal exchange model, that the decision to control the environment and human factors is the average temperature of the heat exchange of the skin. For high-temperature thermal defects existing mine environmental assessment indicators, the average temperature in the heat to the skin comfort zone as an index, the index system is established based on theoretical calculations WSBGT of mine thermal environment for effective assessment, provide the basis for mine cooling design.

The Evaluation System

A specific and rational index system is key to scientific research evaluation. According to the characteristics and status of research-oriented hospitals in China, this study aimed to construct a comprehensive and methodical system for scientific research evaluation. Using bibliometric research, we sorted and refined indices for both domestic and international scientific research evaluation systems, established two-dimensional indices of input and output, and constructed the theoretical framework of evaluation after experts. The Delphi method was adopted to determine the evaluation indices at all levels, and the Analytic Hierarchy Process was used to calculate the weights of the indices at all levels. Twenty experts from different medical fields were involved in the 2 rounds study. Altogether, 7 primary, 14 secondary, and 37 tertiary indices were included in the evaluation system. A matrix was built to conduct the maximum eigenvalue, the consistency indices, and the consistency ratio of each expert in the survey. The index weight coefficients of the indices were calculated accordingly. The model exhibited high consistency, and the credibility of the results was verified. The evaluation system for research-oriented hospitals that we established had high specificity, credibility, and rationality. The evaluation system that we established combines some quantitative evaluation indicators, which are subsequently weighted according to their importance in the field of research-oriented hospital. Evaluation index system will provide the practical manner in the future for comparing the potential academic level and impact of research-oriented hospitals. Moreover, further verification, adjustments, and optimization of the system and indicators will be performed in follow-up empirical studies.

Hierarchy Process

Nutrients carried in upstream rivers to lakes are the main cause of eutrophication. Building near-natural estuarine wetlands between rivers and lakes is an effective way to remove pollutants and restore the ecology of estuarine areas. However, for the existing estuarine wetland ecological restoration projects, there is a lack of corresponding evaluation methods and index systems to make a comprehensive assessment of their restoration effects. By summarizing a large amount of literature and doing field research, an index system was constructed by combining the characteristics of the near-natural estuarine wetlands themselves. It covered environmental benefits, technical management and maintenance, and socio-economic functions, and contained 3 systems, 7 criteria, and 16 indicators. The analytical hierarchy process (AHP) was used to determine the weights of each indicator. The top 5 indicators in order of importance were habitat diversity, total phosphorus (TP), coverage of aquatic plants, ammonia nitrogen (NH3-N), and adaptation to the surrounding landscape. The above evaluation system was used for the comprehensive evaluation of the water purification project in the Fuhe estuarine wetland, Hebei Province, as an example. The results showed that the comprehensive score of the Fuhe estuarine wetland at this stage was 4.1492, and the evaluation grade was excellent. The effect of water purification and ecological restoration was good, and the selected technology was suitable and stable in operation. It had a greater positive impact on the surrounding economy and society and can be promoted and applied. The research results were important for clarifying the advantages and defects of the project and developing efficient and advanced restoration technologies.

Echo fidelity is an important characteristic of radar simulator and it influences accuracy and reliability of radar test directly. This paper introduces the research status of simulator fidelity and sort out the definition and property of radar echo simulation fidelity. Then we propose the numerical calculation methods for individual indicators, including similarity calculation, dissimilarity computing and interval changes three parts. Finally, on the basis of the evaluation system, we propose two calculation methods for entirety fidelity, they are weighted numerical calculation and umbrella figure methods.
