Low Phosphorus Stress

A field experiment was carried out to screen low phosphorus tolerance indexes in common bean. Analysis and comparison of the coefficient of variation of the relative values of phosphorus efficiency-related indexes in 30 common bean varieties subjected to different phosphorus treatments were identified. Plant dry matter weight, phosphorus accumulation, and acid phosphatase activity are important indexes for determining low-phosphorus tolerance. A comprehensive evaluation system for low-phosphorus tolerance in common bean was established using the fuzzy membership function method. Varieties with a composite index ≥ 0.49 were identified as low phosphorus tolerant varieties, including “Longyun 13,” “Longyun 6,” and “Long17- 3525,” while varieties with a composite index ≤ 0.27 were identified as varieties sensitive to low phosphorus, including “Long12-2752,” “NR,” and “Long15-1554.” Bangladesh J.

Taking northwestern China’s Shaanxi Province as the object, this paper constructs a comprehensive evaluation system (CES) for new urbanization and a CES for eco-environment. On this basis, the coordination coupling between new urbanization and eco-environment in Shaanxi and its key factors were evaluated and analyzed, using composite index method, relative development level model, coupling degree model, and coordination coupling degree (CCD) model. The results show that the development level of new urbanization in the province increased linearly, while that of eco-environment rose slowly; the relative development between the two systems gradually changed from the development lag of eco-environment to the development lag of new urbanization; the CCD between the two shifted from medium incoordination to high coordination; the coordinated development between the two systems is greatly driven by per-capita gross domestic product (GDP) in the new urbanization system, and the park area in the eco-environment system.

Objective: The aims of this study are to establish an evaluation system and find the existing problems in the architectural design of township hospitals in the severely cold regions of China. Background: Due to the geographical location and economic factors, development still has some key problems, such as inadequate construction, old facilities, and backward technology, which are more prominent in the severely cold regions. Methods: First, evaluation factors have been selected and determined by literature review and on-site investigation. Evaluation rules have been determined using fuzzy membership function. Then, the analytic hierarchy process is used to determine the weights of the evaluation factors at all levels. Finally, take a township hospital as an example to calculate the comprehensive evaluation results. Results: A comprehensive evaluation index system with 28 elements and 76 factors for the township hospitals in severely cold regions including the basic health service capacity, the emergency capacity, and the climate fitness. Conclusions: The establishment of the comprehensive evaluation system of township hospitals in severely cold areas in this study aims to find out the problems through the evaluation of the existing township hospitals in the severely cold areas and provide guidance for the transformation of existing township hospitals in the severely cold areas. By comparing the scheme evaluation for building hospitals, we shall look for the optimal solution to provide reference for future development in the construction of township hospitals.

Product evaluation is very important for product improvement and development, and subjective product evaluation determines customer’s evaluation of products to some extent, so the purpose of this study is to establish a reasonable subjective product evaluation system. In this study, we comprehensively determine the evaluation indexes based on Kansei engineering (KE), establish an overall product evaluation system by using analytic hierarchy process (AHP), and establish the subjective product evaluation system by classifying the evaluation indexes in the overall product evaluation system into “objective evaluation index” and “subjective evaluation index”, removing the objective evaluation indexes, and retaining the subjective evaluation indexes. Additionally, we select some modern chairs as experimental samples to verify the reliability and validity of this subjective product evaluation system by means of questionnaires. The experimental results show that, in this subjective product evaluation system, the subjective evaluation of the product is positively correlated with the “favorite” level of the product in comprehensive evaluation, and negatively correlated with the “least favorite” level of the product in comprehensive evaluation, indicating that this subjective product evaluation system realizes a symmetry between subjective product evaluation and comprehensive product evaluation. Therefore, it can be concluded that this subjective product evaluation system based on KE and AHP proposed in this study has reliability and validity, and can be used for product evaluation to judge the popularity of products and enhance the competitiveness of products.

Comprehensive Evaluation Model

In the College, performance evaluation system is directly related to the harmonious development of the school. Taking into account the factors in the evaluation system is fuzzy, so this paper uses fuzzy comprehensive evaluation model. But the model is too subjective, so this paper combines neural network and data envelopment analysis method, which ensures that fuzzy comprehensive evaluation model is reasonable and scientific, and good school development and teacher self-interest. The performance assessment process, not only enables the combination of qualitative and quantitative analysis, but also fair and reasonably reflect the achievements of teachers, while this method is easy to use, wide application, and can be well applied in practice.

According to indicators’ information repetition and subjectivity of the indicators’ weight set during the variable fuzzy comprehensive evaluation, Principal Component analysis can help solve the weight of the relative indicators and reduce comprehensive evaluation dimensions of the variable fussy comprehensive evaluation. This paper has made a comprehensive evaluation of the status quo of Yunnan’s low carbon economy development(2005-2009), which turns out to be more practical compared with the mere variable fussy theory analysis, thus, principal component-variable fuzzy evaluation is a kind of feasible way to analyze the regional low carbon development status.
