Subject. The working time of workers at any stage of economic development is a value reflecting the level of labor productivity. Any progress in productivity contributes to changes in the volume of labor costs and the number of employed. Depending on the relationship between the total volume of labor costs and the number of employed, the duration of working time per one worker may change (it may increase, decrease, or remain unchanged). Objectives. The study aims to confirm the importance of such a macroeconomic indicator as the number of employed in varying working hours. Methods. The study rests on the comparative analysis of countries with developed economies based on some indicators like dynamics of the working time fund, dynamics of the number of employed, average number of hours worked during the year per employee, etc. The analyzed timespan is 25 years (from 1991 to 2016). Results. The comparative analysis revealed that in the non-production sphere and the economy as a whole the macroeconomic determinants correlate so that the length of working time per worker reduces. When considering the analysis results for the manufacturing sector, no single trend was identified. Conclusions. One of the key factors affecting the change in working hours is the number of employed. The relationship between the working time fund and the number of employed directly determines the dynamics of working time per worker.

With the development of micro arc oxidation and the growing maturity of the industrialization, the electrolyte service life and stability attract more and more people. In this paper, the electrolyte service life was researched. Under the same technological conditions, it was found that the critical factors affecting the electrolyte service life are the single-processing area and the electrolyte volume. With prolonging the working time of the electrolyte, the gel deposition mass in the electrolyte and the initial voltage always change. The experiment indicates that the electrolyte service life will assume the curve extension when reducing the single-processing area or increasing the solution volume. To some extent, the initial voltage and gel deposition can indicate the active state of the electrolyte, and can be considered as the sign whether the electrolyte service life becomes due.

Abstract. The biggest part of the bridges in Ukraine requires serious restoration works. However, in the literature sources there are no recommendations for choosing effective organizational and technological solutions for the reconstruction of bridges and overpasses. Therefore, the design of methods for optimizing bridge restoration is an urgent task. The working optimization hypothesis is formulated in the article. A general research technique is developed. The algorithm of multicriteria analysis is presented to determine the most effective structural and technological solutions for the restoration of the main structural elements of the studied structures. As a result of the analysis, the most significant indicators of restoration efficiency were determined. These were the cost of restoration of m2 of the bridge and the duration of restoration of the bridge. As factors affecting performance indicators ‒ the intensity of the use of working time and the combination of construction processes, the size of the roadway and the operational condition of the bridge were selected. The planning of the experiment is based on the well-known theory of experimental planning. A 25-point D-optimal plan was selected, which will provide adequate results with significantly fewer experiments than in a full-factor experiment. For calculations is used the program software COMPEX, which is developed at the Odessa State Academy of Civil Engineering and Architecture under the direction of Professor V. Voznesensky. Modelling allows to find the dependencies between the input (intensity use of working time, combination of construction processes, size of the carriageway of the bridge, operational condition of the bridge) and output (cost of restoration of m2 of the bridge, duration of restoration of the bridge) parameters. Dependences data is described with usage of second-degree polynomials obtained by processing the results of a numerical experiment. These dependencies will allow to determine the cost and duration of the restoration of the bridge for varying degrees of damage and the size of the bridge. In addition, to change indicators by choosing the optimal production modes (combination of processes, the intensity of the use of working time). The analysis of the results of a numerical experiment will allow us to assess the influence of organizational and technological factors on the performance indicators of restoration technologies and find areas of factor space that provide optimization of organizational and technological solutions for the restoration of damaged bridges. At the last stage of the numerical experiment, limits are introduced into graphic models (by cost, duration, combination, etc.) and the optimal organizational and technological solutions are determined taking into account the introduced restrictions.

The article examines a significant array of the scientific works devoted to different aspects of the working time dynamics. The conclusion is made that the main measure of this dynamics is the average number of hours worked per worker. This indicator can be used for analysis of all periods of labor activity including seniority. It is stated that the research on the problem shows a long-run trend of working time reduction. The works devoted to the topic also consider other factors affecting length of work: increase of labor productivity, influence of income effect and substitution effect on individual labor supply, motivation of employers, role of trade unions and collective bargaining, labor legislation. There are presented approaches to explanation of differences in the dynamics of working time in the USA and in West Europe. It is taken into account that the working time reduction during the past decades is characterized as one of the preconditions of pension reforms. There are considered works that contain analysis of the effects caused by the changes in working time length, including their impact on workers' health, work-life balance, gender inequality, unemployment rate, labor productivity, environment, perception the life as happy. The article shows a significant interest of researchers to perspectives of the working time dynamics in the context of analysis of J. M. Keynes's prediction about switch to 3-hour shifts by 2030. It is stated that the problem of perspectives of the working time dynamics is becoming one of the key issues in discussing the concept of Universal Basic Income. The article notes the attention of researchers to experiments on the working day reduction to 6 hours.

The results of an empirical study of the working time consumed in strawberry production on Finnish farms are reviewed. Forty growers participated in the study, which took place between 1977—80. The purpose of the study was to determine how much time was consumed in working the fallow ground and during the summer of planting, in the first fruiting year and in the next four or five growth periods. Two cultivation methods were treated separately. The whole strawberry cultivation area was 95,1 ha. In the method in which the earth surrounding the bushes was covered with a black plastic film, the total consumption of working time was 409,0 h/ha using a one-row system and 572,5 h/ha using a double-row system during the fallow period and the summer of planting. During the first fruiting year the figure was 492,5 h/ha and in the next fruiting years 1 348,5 h/ha, including the time spent on harvesting. Where mulch was applied, the corresponding averages were 235,5 h/ha, 612,5 h/ha 1 182,0 h/ha. Factors affecting the variation in the total working time between farms were studied by linear regression analysis. Factors such as e.g. total strawberry cultivation area, the number of plants per hectare and the number of the years the grower had been cultivating strawberries, did not explain the variation in the working time satisfactorily. The yield per hectare, percentage of the different varieties cultivated, planting system, cultivation and picking methods explained only 33 % of the variation in labour output of picking.

This study aims to examine the effect of education level, working time, age, work experience and number of family members on income of female workers in Datar Village and measure the extent of income contribution of female workers producing ketupat casing  to household income. The respondents were selected using the census method and data were analyzed using multiple linear. This study found that education level, working time, work experience and number of family members had a significant effect on income of female workers. Age had no effect on income of female workers. The variable with the strongest relationship to income of female workers was working time. The implications of this study are that in order to increase their income, the female workers should utilize the residue of ketupat casing production in the form of coconut sticks to make other handicrafts, such as woven plates and broom sticks. The crafts can be sold in order to increase income of female workers producing ketupat

In our initial publication on this subject1) we reported results demonstrating that contrast is the most important factor in producing the high image quality required for reliable image analysis. We also listed the factors which enhance contrast in order of the experimentally determined magnitude of their effect. The two most powerful factors affecting image contrast attainable with sheet film are beam intensity and KV. At that time we had only qualitative evidence for the ranking of enhancing factors. Later we carried out the densitometric measurements which led to the results outlined below.Meaningful evaluations of the cause-effect relationships among the considerable number of variables in preparing EM negatives depend on doing things in a systematic way, varying only one parameter at a time. Unless otherwise noted, we adhered to the following procedure evolved during our comprehensive study:Philips EM-300; 30μ objective aperature; magnification 7000- 12000X, exposure time 1 second, anti-contamination device operating.

Strength And Stiffness

Processing polymers from the liquid crystalline state offers several advantages compared to processing from conventional fluids. These include: better axial strength and stiffness in fibers, better planar orientation in films, lower viscosity during processing, low solidification shrinkage of injection moldings (thermotropic processing), and low thermal expansion coefficients. However, the compressive strength of the solid is disappointing. Previous efforts to improve this property have focussed on synthesizing stiffer molecules. The effect of microstructural scale has been overlooked, even though its relevance to the mechanical and physical properties of more traditional materials is well established. By analogy with the behavior of metals and ceramics, one would expect a fine microstructure (i..e. a high density of orientational defects) to be desirable.Also, because much microstructural detail in liquid crystalline polymers occurs on a scale close to the wavelength of light, light is scattered on passing through these materials.
