Background Occupational asthma is a type of asthma caused by exposure to asthma-causing substances in an occupational setting. Its incidence is closely related to the degree of industrial development, but also related to the nature of asthma. In some specific industries, such as workers who are exposed to asthmatic isocyanates for a long time, the incidence of occupational asthma can reach 5%-10%, and the incidence of occupational asthma can even reach 50% or higher among workers engaged in the detergent industry who are in contact with proteolytic enzymes for a long time. Objective To analyze the clinical value of early comprehensive rehabilitation nursing for patients with occupational asthma, methods a total of 48 patients with occupational asthma who were admitted from January 2020 to December 2022 were divided into control group and study group by random number table method The disappearance time of chest tightness and shortness of breath, the disappearance time of wheezing and cough, and the FEV1, forced vital capacity (FVC) and peak expiratory flow (PEF) indexes before and after treatment were compared between the two groups after nursing, the disappearance time of clinical symptoms in the study group was shorter than that in the control group, and the levels of FEV1, FVC and PEF were higher than those in the control group, and the P < 0.05 was significantly improved. 展开更多

Drilling engineering has great uncertainty and it always involves huge investment and high risk. Risk analysis of extended reach drilling (ERD) is very important to prevent complex failures and to improve drilling efficiency. Nowadays there are few reports on how to analyze quantitatively the drilling risk for extended reach wells (ERWs). Based on the fuzzy set theory, a comprehensive fuzzy evaluation model for analyzing risks of ERD is proposed in this paper. Well B6ERW07 is a planned 8,000-meter ERW with a high ratio of horizontal displacement (HD) to vertical depth (VD) in the Liuhua Oilfield, the South China Sea, China. On the basis of the evaluation model developed in this study, the risk for drilling Well B6ERW07 was evaluated before drilling. The evaluation result shows that the success rate of drilling this well is predicted to be 51.9%, providing important rational and scientific information for the decisionmakers. 展开更多

The Hani Rice Terraces System, based on gravity-flow irrigation, is one of the Globally Important Agricultural Heritage Systems(GIAHS) pilot sites selected by FAO in 2010. The water resource plays an important role in the sustainable development of this system. The value of water conserved by the forest is influenced by natural, economic and social factors. In this paper, the water quality, per capita water resources, per capita GDP and population density are chosen as indices to construct an index system for a comprehensive evaluation of water resources value. The weights of these indices are 0.443, 0.31, 0.141 and 0.106 respectively, which are determined by the analytic hierarchy process(AHP) method. The water resources value has been assessed by the fuzzy comprehensive evaluation model. The results show that the water resources value in the Hani Rice Terraces System is 4.25 RMB/m^3. Evaluating the value of water resources in the Hani Rice Terraces System can provide a reference for ecological compensation, for raising public awareness of the importance of protecting the system, and ultimately achieving its sustainable development. 展开更多

The main aim of this paper is to test whether the foreign currency translation adjustments (FCTAs), the largest components of other comprehensive income (OCI) for most firms, are incrementally value-relevant for investors with respect to the net income (NI). Previous archival research on the value relevance of FCTAs has documented a weak or non-existent link between FCTAs and firm valuation (Pinto, 2005). The hypothesized reasons could reside in the econometric method employed, in the use of as-if numbers, and in the missing consideration of the differential effect that exchange rate changes have on firms of varying levels of capital intensiveness. This study adds to the existing literature by empirically testing the value relevance of as-reported FCTAs numbers in the earnings and book value model the Ohlson-like interacted model through panel data techniques. The main finding of this study is that as-reported FCTAs are significantly and incrementally value-relevant, when their parameter estimates are allowed to vary in the cross-section. 展开更多

The nutritive value of pleurotus ostreatus growing in vinegar waste culture materials was evaluated by means of fuzzy comprehensive assessment,In the evaluation, the nutritive composition of the daily necessary of an ordinary adult was used as the standard nutritive structure and that of pleurotus ostreatus cultivated in cotton seed shell culture materials as a contrast. the results showed that the protein content of sporophore growing in vinegar waste culture materials(Sporophore V ) was lower than that of sporophore growing in cotton seed shell culture materials(Sporophore C ), but the nutritive structure of Sporophore V was more rational than that of Sporophore C. This leads to the conclusion that the nutritive value of two kinds of sporophore has no evident difference, and using vinegar waste as a substitute for cotton seed shell to cultivate pleurotus ostreatus does not affect the nutritive value of pleurotus ostreatus. 展开更多

The existing shelf layout methods do not explicitly consider the attention and relevancy of the commodity systematically and thus have failed to capture the invalid associations,resulting in poor sales impact and customer satisfaction.For such shortcomings,in this paper,we propose a mathematical programming approach for shelf layout problems based on comprehensive related value.First,we introduce the concepts of related value considering both attention and relevancy;second,we give the concept of adjacent utility value and the freedom of placement,and further analyze the impact of the same commodity on surrounding commodities due to different placement positions;third,we establish a new comprehensive related value-based commodity layout optimization model(CRV-CL)and provide the solution steps integrating with a genetic algorithm.Finally,we analyze the characteristics of CRV-CL through a specific case.The simulation results indicate the overall relevancy after applying the CRV-CL model. 展开更多
