Main Effects

At present, the main methods of analyzing the reasons why construction cost always got out of control are qualitative analysis based on the practical construction experiences in the construction cost management. And these analyses were easily affected by subjective factors. By introducing a complete decomposition model, the influencing factors of the incontrollable construction cost in the construction stage can be decomposed to the effect of quantity changes and the effect of unit price changes of each kind of construction. A quantitative analysis will be carried on subsequently to analyzing these effects to find the main effects of the whole construction cost changes. This model made the analysis more objective and scientific, and can accumulate the data for new or planned similar constructions. To illustrate, the decomposition on construction cost changes of a small civil project is carried out.

The development of medical E-commerce is facing many challenges and constraints from government, businesses, individuals and other aspects. This paper, on the basis of the full investigation, elaborates Interpretative Structural Modeling (ISM) to make qualitative analysis. The modeling shows a clear hierarchical relationship between the various influencing factors and differentiates the surface factors, shallow factors, middle factors and underlying factors to expect to provide some suggestions for the development of medical E-commerce, and also lay the theoretical foundation for the quantitative analysis.

In recent years, the rapid development of the national economy has brought rapid growth in electricity demand; the power grid construction has entered a period of rapid development. Construction of power transmission line project is an important part of power grid construction，the cost management of construction stage, it is of great significance for the entire project cost management, improve the efficiency of construction enterprises. In this paper, based on the theory of cost management in construction stage, from the three aspects of social and economic factors, human factors and natural factors, analyzed the current situation and problems of transmission line engineering construction cost management and to the actual engineering data are discussed. Finally, in view of the present situation and problems of the construction cost management, this paper puts forward some suggestions.

Crataegi folium have been used as medicinal and food materials worldwide due to its pharmacological activities. Although the leaves of Crataegus songorica (CS), Crataegus altaica (CA) and Crataegus kansuensis (CK) have rich resources in Xinjiang, China, they can not provide insights into edible and medicinal aspects. Few reports are available on the qualitative and quantitative analysis of flavonoids compounds of their leaves. Therefore, it is necessary to develop efficient methods to determine qualitative and quantitative flavonoids compounds in leaves of CS, CA and CK. In the study, 28 unique compounds were identified in CS versus CK by qualitative analysis. The validated quantitative method was employed to determine the content of eight flavonoids of the leaves of CS, CA and CK within 6 min. The total content of eight flavonoids was 7.8–15.1 mg/g, 0.1–9.1 mg/g and 4.8–10.7 mg/g in the leaves of CS, CA and CK respectively. Besides, the best harvesting periods of the three species were from 17th to 26th September for CS, from 30th September to 15th October for CA and CK. The validated and time-saving method was successfully implemented for the analysis of the content of eight flavonoids compounds in CS, CA and CK for the first time.

AbstractThe aim of this systematic review was to perform qualitative and quantitative analysis on the toxic effects of chloroquine (CQ) and hydroxychloroquine (HCQ) on skeletal muscles. We designed the study according to PRISMA guidelines. Studies for qualitative and quantitative analyses were selected according to the following inclusion criteria: English language; size of sample (> 5 patients), adult (> age of 18) patients, treated with CQ/HCQ for inflammatory diseases, and presenting and not presenting with toxic effects on skeletal muscles. We collected data published from 1990 to April 2020 using PubMed, Cochrane Library, EMBASE, and SciELO. Risk of bias for observational studies was assessed regarding the ROBIN-I scale. Studies with less than five patients (case reports) were selected for an additional qualitative analysis. We used the software Comprehensive Meta-Analysis at the confidence level of 0.05. We identified 23 studies for qualitative analysis (17 case-reports), and five studies were eligible for quantitative analysis. From case reports, 21 patients presented muscle weakness and confirmatory biopsy for CQ/HCQ induced myopathy. From observational studies, 37 patients out of 1,367 patients from five studies presented muscle weakness related to the use of CQ/HCQ, and 252 patients presented elevated levels of muscle enzymes (aldolase, creatine phosphokinase, and lactate dehydrogenase). Four studies presented data on 34 patients with confirmatory biopsy for drug-induced myopathy. No study presented randomized samples. The chronic use of CQ/HCQ may be a risk for drug-induced myopathy. There is substantiated need for proper randomized trials and controlled prospective studies needed to assess the clinical and subclinical stages of CQ/HCQ -induced muscle myopathy.

Main Factor

Regarding analysis of load characteristics of a power grid, there are multiple factors that influence the variation of load characteristics. Among these factors, the influence of different ones on the change of load characteristic is somewhat different, thus the degree of influence of various factors needs to be quantified to distinguish the main and minor factors of load characteristics. Based on this, the grey relational analysis in the grey system theory is employed as the basis of mathematical model in this paper. Firstly, the main factors affecting the load characteristics of a power grid are analysed. Then, the principle of quantitative analysis of the influencing factors by using grey relational grade is introduced. Lastly, the load of Guangzhou power grid is selected as the research object, thereby the main factor of temperature affecting the load characteristics is quantitatively analysed, such that the correlation between temperature and load is established. In this paper, by investigating the influencing factors and the degree of influence of load characteristics, the law of load characteristics changes can be effectively revealed, which is of great significance for power system planning and dispatching operation.

Qualitative Analyses

Retranslations of the Qur’an constitute an intriguing site of research with particular premises governing their production, dissemination and/or reception in Turkey. Its inherently religion-oriented context is accompanied by discussions on the sacred status of the source text, arguments on its untranslatability, translatorial human agency vis-à-vis the Holy creator, acknowledged Arabicity of the source text, etc. In this regard, each new translation of the Qur’an in Turkish is released with a motivation to justify its necessity amid abundant retranslations available in the target repertoire. Various approaches towards the conceptualization and instrumentalization of these Qur’anic translations create a meta-narrative on its own right. This study aims at exploring this particular discourse on the retranslations of the Qur’an with a bi-faceted study design composed of quantitative and qualitative analyses. The quantitative analysis focuses on the numeric changes of Qur’anic retranslations in respective decades, whereas the qualitative analysis concentrates on the statements of the translatorial agents on the motives behind their translational production. By shedding light on the discursive narrative postulated upon these retranslations, it is claimed that social, political, cultural and financial concerns have prevailingly governed the reproductions of this canonical work in Turkey. Keywords: Qur’an translation, religious-text translation, retranslation, discourse analysis.
