Climatic and geographical conditions that effect on the health of sailors during marine voyage

The prolonged availability of seafarers on board of water vehicle during voyages forms the features of professional labor activity. When assessing the medical and sanitary situation of life and vital activity of the crew on board a ship, it is necessary to take into account a set of conditions that are integrated into a single notion — «ship environment ». The ship’s environment affects the personnel’s body for the entire period while people are on the voyage. It can cause changes in the state of health. The article presents a review of the literature devoted to the study of the influence of climatic and geographical factors accompanying maritime labor. Natural factors occupy a significant share among the large effects of the ship’s environment that affect the health of seafarers and, accordingly, their ability to work. Among them, the greatest contribution is made by temperature, physico-chemical properties of air, photoperiodic fluctuations. The homeostatic systems of the seafarers ‘ body are very closely dependent on the natural situation of the seas. These conditions impose high requirements and can cause the development of premorbid and pathological conditions. To ensure the protection of the health and working capacity of the crew, it is necessary to study the influence of external factors. The main directions for ensuring the safety and strengthening of the health of seafarers are: forecasting and prevention of health disorders, prenosological diagnostics and timely medical support, rehabilitation measures in the post-voyage period.

Specifics of the color solution of the modern coworking center

The purpose of the article is to determine the features of the color component of interior design and to identify the aesthetic and artistic features of the color scheme of a modern work area on the example of the capital's coworking centers. Methodology. Art and art analysis in the aspect of design creativity is applied; structural-semiotic analysis, which involves the identification of symbolic, differentiating functions that are embedded in the color of the interior of the coworking center; the method of structural analysis, which contributed to the study of sign systems of the color of the interior of coworking centers with the decoding of the meanings embedded in them; method of comparative analysis, which establishes common features in the perception of color by modern man, identified the characteristics of the role of color in the interior design of the workspace. Scientific novelty. The semantic significance of color in the interior design of a coworking space is studied; the informativeness of color is analyzed on the basis of three parameters (tone, saturation, and brightness); the compositional and decorative function of color is considered; the aesthetic and artistic features of the color scheme of the modern work area are revealed on the example of Kyiv coworking centers and the priority color scale is determined, which contributes to the increase of working capacity. Conclusions. The basis of color perception – physiological, psychological, and aesthetic factors that determine color associations, semantics, and symbolism of color – are ancient archetypes formed under the influence of socio-economic and sacred factors. A variety of color harmonies are widely used in modern workspaces, in the process of organizing production processes, to create psychological accents that improve performance and reduce fatigue. In the context of coworking center design, the approach to color interior design is based primarily on the desire to create an atmosphere that promotes positive emotions, inspires workers to cooperate and productivity. The study found that the rich creative source of the artistic image of the interior of the coworking center is played by archetypes, which involve the image-associative thinking of designers. The color component is not limited to the characteristic scales that meet the latest trends – it is much wider and demonstrates the diversity of design searches. Key words: coworking center, interior design, colors, semantics, color, working capacity.

The quality of professional civil servants in the Vietnamese home affairs sector

In each country, civil servants are identified as the labor force exercising the state power to manage social development, so their quality is often clearly defined with general requirements in line with the characteristics of the civil service and the specific ones of each industry. In Vietnam, the quality standards for civil servants are clearly defined in the Law on Cadres and Civil Servants in 2008, with general provisions applicable to all of them in the state apparatus. Based on this Law, all industries have their regulations on the quality of civil servants by their characteristics. In this study, we focus on analyzing the quality of professional civil servants in the Home Affairs sector according to its standards based on issued legal regulations, including Political quality, Professional qualifications, Working capacity, and Work results. In this study, a qualitative method is employed to collect secondary documents combined with a quantitative one to conduct a direct survey of 500 managers from the Departments of Home Affairs in 12 provinces representing three provinces of Vietnam.

The prevalence of low back pain among nurses in Serbia

BACKGROUND: The presence of low back pain in nurses is becoming increasingly prominent and it has significant impact both on the individual as well as on the community. OBJECTIVE: The aim of this study was to determine the prevalence of low back pain among practicing nurses. METHODS: The research has been conducted in five health care institutions in the area of Vojvodina. Data were collected using the Nordic Musculoskeletal Questionnaire (NMQ). RESULTS: Five hundred and twelve nurses participated in this study. Most of the participants (93.95%) indicated that they experienced discomfort or pain in the lower back in the last 12 months. Due to low back pain, 61.95% of participants had reduced working abilities and 76.09% of participants have never taken time off from work. CONCLUSIONS: Due to low back pain nurses have a reduced working capacity, but they nevertheless rarely seek medical help or the change of the work place. The implementation of better ergonomic approach and adequate organization of work could reduce the occurrence of low back pain.

КІНЕТОСТАТИЧНЕ ДОСЛІДЖЕННЯ ШАРНІРНИХ ПРОСТОРОВИХ МЕХАНІЗМІВ ГАЛТУВАЛЬНИХ МАШИН (ЧАСТИНА 1: ДОСЛІДЖЕННЯ МЕХАНІЗМУ З ДОДАТКОВОЮ РУХОМОЮ ЛАНКОЮ – КОРОМИСЛОМ)

Kinetostatic study of a statically determined hinged spatial mechanism without redundant (passive) connection with an additional movable link – a rocker arm of a machine for processing parts, in which the working container performs complex spatial movement. Methodology. The essence of the kinetostatic research was to determine the radial and axial components of the reactions in all rotational kinematic pairs of the hinged statically defined spatial mechanism of the machine for processing parts, when it is idling. The kinetostatic study was implemented using the SolidWorks 2016 computer-aided design system with preliminary 3D modeling of this machine design with an additional moving link – a rocker. Results. In the course of the kinetostatic study, 3D modeling of a machine with an additional movable link – a rocker arm in the SolidWorks 2016 computer-aided design system was carried out, the maximum values of the radial and axial components of reactions in all rotational kinematic pairs of the machine for processing parts were determined, the effect of changing the center distance of the intermediate connecting rod (working capacity ) on the increase in the maximum values of the reactions in all rotational kinematic pairs. Scientific novelty. The relationship between the center distance of the intermediate connecting rod (working capacity) and the change in the maximum values of the reactions in all rotational kinematic pairs of the machine for processing parts is determined. As a result, it becomes possible to determine the maximum permissible center distance of the intermediate connecting rod to ensure the durable operation of the machine. Practical significance. It is determined that the nature of the change in the maximum values of the radial and axial components of the reactions in each rotational kinematic pair of the spatial mechanism depends on the value of the coefficient characterizing the ratio of the center-to-center length of the intermediate connecting rod (working capacity) to the center-to-center length of the driving or driven connecting rods of the machine. The range of variation of this coefficient has been determined, within which it is rational to design this machine design. The results obtained can be used in the corresponding design bureaus of machine-building enterprises at the stage of designing tumbling equipment with a complex spatial movement of working containers.

Exercise-Based Cardiac Rehabilitation: Secondary Data Analyses of Mortality and Working Capacity in Germany, 2010–2017

Background Exercise-based cardiac rehabilitation is safe and implemented in international cardiac rehabilitation guidelines. Evidence for long-term health effects is scarce and rare for health care service research. Objective The aim of this study is to evaluate the effectiveness of exercise-based phase III cardiac rehabilitation programs in improving mortality and working capacity outcomes. Methods The present analyses used claims data of the German pension fund from 2010 to 2017. Overall, 54,163 patients with coronary heart disease (ICD10 I20.–I25.) were included and followed up for exercise-based cardiac rehabilitation participation (mean 4.3 ± 1.9 years). All patients were categorized according to participation duration (long: ≥ 90 days, short: < 90 days, no). The effectiveness of exercise-based rehabilitation was analyzed by calculating adjusted hazard ratios for mortality and reduced working capacity in relation to program participation. Results Of all the cardiac patients, 57.6% received medical recommendations for exercise-based phase III rehabilitation, and 16.8% participated in this rehabilitation. In total, 1776 (3.3%) patients died during the study period, and 3050 (5.5%) received reduced earning capacity pensions. Mortality risk was nearly doubled for those who did not participate in exercise-based cardiac rehabilitation compared to those who participated for a long duration (HR 1.97, 95% CI 1.60–2.43) and 44% higher compared to a short participation (HR 1.44, 95% CI 1.03–2.01). Furthermore, the risk of reduced working capacity was higher for those who did not participate compared to those who participated for a short duration (HR 1.24, 95% CI 1.00–1.54). Conclusion Exercise-based phase III cardiac rehabilitation is independently associated with reduced mortality and reduced loss in working capacity. Strong efforts should be made to increase participation rates to improve cardiac patients care.

Working capacity of deep networks with topology attacks

Deep learning plays an important role in the development of artificial intelligence (AI) technology. The security of deep networks has become the crucial thing to be considered. When the deep learning algorithms are implemented in the hardware platform, the interference for topology structure will appear because of cyber-attacks. We analyze the working capacity of acyclic deep networks under the topology attacks and injection attacks. Considering the topology structure of the deep network, the maximum working capacity is studied under the topology attacks and injection attacks. Furthermore, the robustness of the random networks is researched and the structural robustness index (SRI) is proposed to measure the toleration for the topology attacks. This work supplies some suggestions for building a robust deep network and improving the endogenous safety and security (ESS) of the deep networks.
