Rural Poverty Identification and Comprehensive Poverty Assessment Based on Quality-of-Life: The Case of Gansu Province (China)

Rural poverty has received extensive attention worldwide. Eliminating poverty and achieving common prosperity are the major tasks for China to build a well-off society in an all-round way. Based on the evaluation results of quality of rural life (QRL) and relative poverty index (RPI), this paper identifies and classifies the poor objects using importance–Performance analysis (IPA) method and poverty degree model. The results were as following: (1) QRL has obvious regional differences, and its value gradually decreases from west to east, which is opposite to the spatial distribution pattern of RPI. In areas with high QRL value, the RPI is lower. (2) Fifty counties and districts are clustered in the second quadrant of IPA quadrant map, i.e., Low QRL-High RPI, and the lower quality-of-life corresponds to the higher degree of relative poverty. (3) The coincidence between the poverty-stricken counties and the poverty-stricken counties of the country identified as 84.48% by IPA method, which indicates that the accuracy of poverty delineation based on income is high. (4) Gansu Province is dominated by highly impoverished areas, accounting for 60% of the total number of impoverished counties. The results of comprehensive poverty classification are in line with the actual situation of impoverished counties. In counties with higher CPL, the poverty level is deeper. It is more difficult to get rid of poverty. This study can provide theoretical basis and decision-making reference for the formulation and implementation of Poverty Alleviation Policies in the late stage of underdeveloped areas in western China.

Evaluation of the quality of compound liquorice tablets by DSC and HPLC fingerprints assisted with dissolution

A systematic quantitative fingerprint method (SQFM) was applied to evaluate the quality of compound liquorice tablets (CPLTs) in this paper. The method contained three main parameters: macroscopic qualitative similarity (Sm), macro quantitative similarity (Pm) and a leveling variance coefficient (α), which were used to analyze the similarity of curves and evaluate the fingerprints of CPLTs. Firstly, Differential Scanning Calorimetry (DSC) was applied to analyze CPLTs and the active raw materials (RMs). At the same time, the change of appearance and weight during DSC testing revealed that the two main thermal processes of CPLTs were between 240–320 °C and 400–500 °C. The DSC fingerprint (DSC-FP) of 49 batches of CPLTs was collected and the enthalpy values were calculated. Then, we studied the dissolution of CPLTs, collected ultraviolet fingerprints (UV-FP) and the Pm was used to plot the dissolution curve. The results showed that the dissolution and enthalpy had a negative correlation, and the formula was y= −32.38x+3207.49 with r= −0.83. Finally, the High Performance Liquid Chromatography fingerprint (HPLC-FP) of 49 batches of CPLTs was collected and assessed by SQFM. The results of quality evaluation of CPLTs by HPLC-FP combined with DSC-FP showed that 49 batches were divided into 4 levels, which could evaluate the quality of the drug more comprehensively and objectively.

Comparison of Industrial Microwave Drying and Fluidized Bed Drying Techniques on the Quality of Jasmine Instant Rice

Nowadays, most people are living with busy schedule. Consequently, people have to select the most convenient option to save their time. Instant rice is considered as one of the possible solutions to serve most people present lifestyle. However, the problems with instant rice including slow rehydration and poor quality affect the consumer acceptability. This research focused on drying methods in order to improve the quality of instant rice. Two drying methods were investigated: Industrial microwave drying (IMD) and fluidized bed drying (FBD). The results of quality evaluation revealed that whiteness and texture of IMD had no significant difference with freshly cooked rice. In addition, IMD had better quality of product compared to FBD in term of texture and whiteness. IMD (6,400 watt, 2,450 MHz) was appropriate drying method to produce instant rice because of the fast rehydration time for 4 minutes by boiling water while FBD (85°C 60 min) took slower rehydration time for 9.5 minutes. Furthermore, after rehydration, the rice physical appearance of FBD and IMD were not coagulated and not broken and good quality. Therefore, instant rice processing by IMD is recommended for the instant rice production at the industrial scale.

Biscuits were formulated using a 50/50 wheat and purple rice flour mix containing mixed spices, galangal, and defatted green‐lipped mussel powder (Perna canaliculus) added in the range of 5–15% of the total biscuit weight. The fortified biscuits had higher protein (26.36%), fiber (52.90%), and ash (6.00%) contents and a lower total fat (5.64%) content compared to the control biscuits. The in vitro starch digestibility and predicted glycemic index (pGI) decreased in the fortified biscuits by 18.95% and 6.18%, respectively, while the in vitro protein digestibility increased by 3.73%, corresponding to the increased levels of defatted mussel powder present. The spread ratio and hardness of the fortified biscuits also increased significantly. The color values of the fortified biscuits after the incorporation of different levels of defatted mussel powder showed significant changes, with a darkening of the biscuit surface and a lowered browning index compared to the control biscuits. Results of the sensory quality evaluation showed that incorporation of defatted mussel powder into the biscuit mix of up to 15% showed no significant differences in liking scores in terms of color, overall appearance; whereas, the flavor and overall acceptability scores were significantly lower than the control biscuits. Overall, defatted mussel powder can be successfully incorporated into biscuit mixes to enrich the protein, fiber, and antioxidant contents of the biscuits.

Water Quality Improvement Plans of Daeho Reservoir based on the Analysis of Watershed Characteristics and Water Quality Modelling

For effective improvement of water quality in Daeho reservoir, this study implemented various analyses including the tributary water quality and flowrate monitoring, analysis of water quality in agricultural drainage, Daeho reservoir and influent from Sapgyo reservoir, pollutants content of sediment, and pollutant discharge characteristic in Daeho reservoir watershed. The water quality of tributaries in Daeho reservoir watershed was good, but due to the drought, the water quality of Daeho reservoir exceeded the class IV of water environment standard in reservoir because the water from Sapgyo reservoir was introduced into the Daeho reservoir. The main pollution sources in the Daeho reservoir watershed were population and livestock. Careful management of livestock pollution sources should be needed because the pollutants content of sediment, which located in spraying area of liquid livestock manure in Daeho reservoir reclaimed land, were high. The water quality of influent from Sapgyo reservoir should be preferentially improved for improving the water quality in Daeho reservoir. As the evaluation results of water quality in Daeho reservoir for the effect of water quality improvement using water quality model, it was found that the water quality in Daheo reservoir due to the biological and chemical treatment of forty percent of the incoming water from Sapgyo reservoir would be predicted satisfaction of the class IV of water environment standard in reservoir. Key words: Daeho Reservoir, Sapgyo Reservoir, Drought, Watershed Characteristic, Water Quality Modelling, Water Quality Improvement Plan

A Method for Evaluating Service Quality with Hesitant Fuzzy Linguistic Information

Service quality evaluation is vital to identifying the strengths and weaknesses of the services provided by service organizations. In practical situations, because of customers’ inherent uncertainty and hesitancy, hesitant fuzzy linguistic information is often employed by customers to assess expected and perceived services. The purpose of this paper is to propose a novel method for evaluating service quality based on the use of hesitant fuzzy linguistic term sets (HFLTS). In this method, customers’ comparative linguistic expressions concerning the expected service, perceived service, and attribute weights are transformed into HFLTS. By using a transformation formula, HFLTS are expressed as trapezoidal fuzzy numbers. Then, based on Gap 5 of the Parasuraman Zeithaml Berry service quality model, calculation formulas and a related theoretical analysis of the discrepancy degree between fuzzy perceived service and expected service are given. A fuzzy evaluation result for each dimension is determined by aggregating the discrepancy degrees of customers with respect to all attributes in the same dimension. Furthermore, a linguistic evaluation result for each dimension is achieved by calculating and comparing the similarity degrees between the fuzzy evaluation result and the predefined linguistic variables. On this basis, an overall service quality evaluation result is determined by aggregating the evaluation results for all dimensions. Finally, an example is used to illustrate the feasibility and effectiveness of the proposed method.

INNOVATION OF HIGH NUTRITIONAL VALUE SNACK BARS FROM DATES AND EXTRUDED CEREALS

In Egypt, dates are considered a strategic crop. Egypt occupies the first place in the world in date production, with annual production about 1.5 million tons. Dates are known for their high concentrations of sugar. An attempt was made to produce a product, from nationally available materials, with enhanced nutritional value and acceptability for consumers. The study aimed to produce a novel date bar by using date, date syrup, sesame seeds, extruded whole wheat, extruded hull-less barley, extruded wheat barley, wheat-rice mixtures, pop-corn and a mixture of all. In this study, products were prepared with no sugar additives, since dates and date syrup are rich in natural sugars. Various analysis (proximate composition and sensory evaluation) were performed. Results showed that date fruit bars were rich in protein, fat and carbohydrates with good energy values. Texture-wise, products were easy to bite and chew. Results of sensory quality evaluation indicated that dates, date syrup and puffed cereals have excellent potential to be converted into snack bars. Results generated in this study show that date-based fruit bars may be expected to fulfill some the requirements of health-conscious consumers. It is anticipated that this product will attract both children and adults.

An Evaluation Method of Comprehensive Product Quality for Customer Satisfaction Based on Intuitionistic Fuzzy Number

How to maximize customer satisfaction is an important research topic in the service quality evaluation. This paper proposes an evaluation method of comprehensive product quality for customer satisfaction based on the intuitionistic fuzzy number. In this method, we design a questionnaire and investigate the customer’s language evaluation information of product quality evaluation, including product expectations and product perception at first. And then, the product quality evaluation model is obtained by Delphi method; that is, the first-level evaluation indexes and the second-level evaluation indexes are obtained and the weight vector of each evaluation index is determined. Next, language evaluation information translates into corresponding fuzzy numbers using intuitionistic fuzzy numbers. Therefore, the results of the product quality evaluation of the production system are obtained using the weighted mean method. Finally, an example is used to illustrate the feasibility and effectiveness of the proposed method.

Although China is promoting urban sustainable development and developing sustainable experimental areas, it is vital to identify scientific methods and obtain data to analyze this development. In recent years, metadata has been regarded as an effective method to improve data quality. This study focused on the characteristics of an urban sustainable development analysis index system which is based on a metadata management system using software engineering by analyzing the data source, collection method, and application method etc. The aim of this study was to effectively and efficiently collect useful data from the sustainable development experimental area. According to the metadata standard which was developed by "research and demonstration on urban sustainable development capacity assessment and information management key technologies" in 12th Five-Year science and technology support program, we used fourteen key evaluation metadata items in this standard as benchmarks, including data release date, data release form, spatial range, time range(start time and end time), statistical frequency, data security limit classification, data description, Online resource link address and information of data statistics institution(institution name, contacts, contact number, address and e-mail address). Comparing the results of data quality evaluation before and after using a metadata tracking method through the quantitative data quality scoring method, we found that the data are more reliable, comparable and constant when using metadata. This research shows several advantages in controlling and protecting urban sustainable development analysis data quality when applying the metadata theory. Further, the development of a specific urban sustainable development analysis metadata management system could improve the comprehensive evaluation result of the data. 参考文献 相似文献 引证文献
