In this paper, safety production environment mechanism is analyzed, and An evaluation model for safety investment benefits is presented. From the viewpoint of proion system situations and capital flow transition between safety investment and accident loss in enterprises, the relationship of production investment, production output and safety investment benefits are deduced. By comparing production systems with and without safety investment, the variation rules and their model between safety investment benefits and accident loss in extreme and actual situations are analyzed. Finally, the expressions of safety investment benefits are derived for general actual cases. The proposed evaluation model can provide an important and scientific basis to evaluate safety investment benefits and be employed in a number of ways to improve it for enterprises and safety administrator.

Water conservancy and hydropower engineering construction system is a typical multi-level complex system and its swarm identity is apparent to brittleness cumulative effect. The brittle sources are interlinked and associated, thus there are topological forms of different brittle sources, which make the relationship of brittleness evaluation cumulative function to be non-linear. In traditional evaluation methods, indicators are usually assumed to be independent, which does not satisfy the non-linear characteristics of water conservancy and hydropower engineering construction system brittleness. Thus, in this paper, weak monotonic of fuzzy measure is used to replace the addition function, brittleness evaluation model of water conservancy and hydropower engineering construction system based on Choquest integral is built.

It is necessary to have a frame of reference to understand the work of each cabinetmaker in the Royal House of Spain. This research on the Royal Cabinetmaking Workshops try to systematize its structure within the conglomerate of court artists and the relationship of each cabinetmaker with the royal administration. It is essential to know how these workshops were created, their purpose, who directed them, what their day-to-day life was like and how they disappeared. In this way, workshops, cabinetmakers and furniture have appeared that have not been given the importance they deserve. Dates and attributions are also corrected. On the other hand, the authorship of important furniture sets is justified and the ability of cabinetmakers to design their own furniture is once again demonstrated. In short, it is an approach to royal furniture delving into the crown production systems.

ABSTRACTThe recent development of a more systematic, scientific basis for knowledge in electrodeposition technology is discussed, focussing on the influence of microstructure on deposit properties. Internal stresses, tensile strength, ductility, preferred orientation and the ability to electrodeposit amorphous materials are considered. In particular the unique influence on these properties of small quantities of chemical additives is discussed. The application of current modulation techniques during electrodeposition is described as an alternative means of controlling structure and properties.

The method of drying licorice is an important factor affecting the quality of the final product. To determine the best processing method of licorice postharvest, we investigated the interaction of increasing aridity between the endophytic microorganisms and the accumulation of metabolites. Samples from the roots of licorice growing along an aridity gradient during the natural drying process were collected, and the metabolic components, the content of the main active substances and the dynamic changes of the endophytic microbial community were assessed. The glycyrrhizic acid and liquiritin contents decreased slightly or remained flat during natural drying, whereas those of liquiritigenin and isoliquiritigenin increased slightly. Moreover, the Shannon index of endophytic microbial diversity of licorice was the highest in the fresh period and showed a downward trend during the drying process. When the licorice were fresh, Cladosporiaceae and Burkholderiaceae were the dominant family present, but after drying, Nectriaceae and Enterobacteriaceae were the dominant families. A similar trend was also found in which the differential metabolites of licorice were reduced during natural drying. Furthermore, correlation analysis between dominant families and differential metabolites showed that there was a correlation between the two. Therefore, fresh processing is an effective drying method to ensure the quality of licorice. This study revealed the relationship of endophytic microbiota and changes in the licorice metabolites during different stages of drying, which provided a scientific basis for the drying method of licorice.

Oribatid mites (Acari: Oribatida) are one of the most numerous and dominant groups of soil inhabitants that play an important role during soil formation and its biological processes. The paper presents a full list of oribatid mites known of Vietnam (excluding Acari: Astigmata) based on the collected and identified species as well as on literature records from 1967 to 2019. Totally, 726 plus one oribatid species belonging to 245 genera, 90 families, and 41 superfamilies, together with the specimen’s data have been recorded in Vietnam. These oribatid mites species are identified and analyzed along with their distributions known according to the eight natural and man-made factors, including (1) natural region, (2) soil type, (3) climate zone caused by elevation above sea level, (4) habitat type, (5) distance to the sea, (6) climate season, (7) soil vertical distribution, and (8) oribatid body size. This will be an important scientific basis for further analysis on the relationship of the formation of oribalid mite complexes under the influence of natural & man-made factors, contributing to sustainable management of soil ecosystem in Vietnam.

The dangerous events often happen in coal-fired power plant and its influence is very serious. Use entropy weigh method to determine the weight of index is very popular, it not only consider the key factors but also make a quantitative analysis for the interaction and coordination among different index. It is about how to make the function of system security greater than the sum of each single subsystem. The case study shows that the comprehensive safety evaluation model can integrate the safety factor and analyze the nonlinear effect of each index so as to make the evaluation result more reasonable, then, it can supply the scientific basis for safety production management of enterprise.

The results of the analysis of architectural and landscape interactions in the valley spaces of the rivers in Ukrainian Carpathians are presented in the article. The analysis was made at the scale level of elements of the architectural landscape. It was the next step after preliminary studies at the two highest scale levels - the level of settlement systems and at the level of settlements. The goal is to create a scientific basis for the methodical bases of the architectural and landscape arrangement of river valley spaces in Ukrainian Carpathians. Architectural and landscape interactions at a lowest scale level (level of an architectural landscape elements) are most clearly manifested in the aesthetic aspects. Elements of the architectural landscape are divided into natural and anthropogenic. The last ones were studied, which in turn are divided into urban elements, architectural objects and engineering structures. 30 elements were analyzed by functional-planning and aesthetic characteristics, of which 7 are presented in the article. It was revealed, that the large buildings, which visually dominate the relief, spoil aesthetics and identity of the valley landscape. When the traditional superficiality is exceeded, the feeling of the dominant influence of natural components on the local architectural environment is lost. The use of artificial finishing materials or too bright colors distorts the image and disintegrates the environment. It was established, that the best aesthetic effect in the relationship of architecture and landscape is achieved by applying traditional local styles in construction, in which there is an organic unity of nature and architecture through scale and form, as well as the use of natural materials in decoration.
