Resumen:La organización de la producción ha venido sufriendo una rápida transformación desde hace casi dos décadas, con los cambios de los equipos de trabajo, las técnicas administrativas de calidad total y la producción justo a tiempo. Estas transformaciones han resultado en una mejora en la productividad en el trabajo, pero también en las repercusiones negativas sobre la vida de los trabajadores. Si las consecuencias positivas de la transformación del proceso de trabajo con respecto a la productividad están más que compensadas por las consecuencias negativas en las condiciones de trabajo, es posible que el movimiento de transformación del proceso de trabajo sea nocivo para la sociedad como un todo.Palabras clave : organización de la producción; equipos de trabajo; técnicas administrativas; calidad total; producción justo a tiempo; productividad. Abstract:The organization of production has undergone a rapid transformation for almost two decades, through changes in the work teams, the total-quality administrative techniques, and the just-in-time production. These changes have resulted in a better labor productivity, but also in negative effects on workers' lives. If positive consequences of the transformation of labor process with regard to productivity are more than compensated by the negative impact on working conditions, the labor process's change movement can be harmful to society as a whole.Key words: organization of production; work teams; administrative techniques; total quality; just-in-time production; productivity.

Polymer processing belongs to the category of hazardous industries and requires a deep and comprehensive analysis of the production environment from a hygienic point of view in order to minimize the negative impact on human health and components of the biosphere. The purpose of the study. It is important to study a set of adverse factors that affect employees in the process of processing polymer waste, to establish the relationship with the development of general and occupational diseases. Results and discussion. It has been established that the working conditions of the process of processing polymer waste have a combined effect on the body caused by a set of adverse production factors of different actions. The main ones are: dust in the air of the working area with polymer dust with mixed and unstable composition over time, noise, cooling microclimate, difficulty of work. The excess of maximum permissible concentration for dust load on the body of workers in the process of mechanical processing of PPV is from 1.35 times to 1.74 times, at the workplaces of the baler and shredder and unloading-packing operator (working conditions class 3.1). Exceedance of the sound pressure level in the range from 2 dBA to 15 dBA was recorded at all workplaces (working conditions class 3.2). The parameters of the microclimate at all workplaces, except for the forklift operator, belong to the harmful class of working conditions 3.1. According to the severity of the labor process, the working conditions of employees vary from allowable 2 (operator of the technological process) to harmful 3.2 (baler and shredder operator). In terms of intensity, the working conditions of all employees belong to harmful class 3.2, due to the significant noise load, which prevents the capture and transmission of information between participants in the processing process, as well as timely receipt of audio signals from the process operator and equipment. Mostly working conditions of employees in the process of processing PPV mixtures belong to class 3.2, except for the forklift operator (class 3.4). As for the integrated assessment, according to the hygienic classification, working conditions of operators of unloading-packing, crushing, technological process and baler are evaluated according to class 3.2, and the truck operator - 3.4 according to state sanitary rules and regulations "Hygienic classification of labor according to the indicators of harmfulness and danger and the intensity of the labor process" (order of the Ministry of Health dated 08.04.2014 No.248,), which can lead to the development of work-related diseases

Introduction. Professional groups of railway workers engaged in the repair of wagons are directly responsible for the safety of railway traffic. The analysis of literature testifies to insufficient attention of researchers to the hygienic problems associated with labor activity of workers of wagon-repair production.The aim of the study is to assess the occupational risk to the health of wagon repair workers, due to the impact on them of factors of the working environment and the labor process.Materials and methods. The study used comprehensive hygienic studies using the methodology of occupational risk to worker’s health.Results. The leading factors of the working environment (class of working conditions 3.2–3.4), which are exposed to workers depending on the specifics of the work performed. Identified professional groups with medium (significant) high (unbearable) and very high (intolerable) category of a priori occupational risk: in wagon meintenance workshop — 17 groups (94% of jobs), in a wagon assembly workshop — 11 groups (80% jobs), in wagon wheel workshop — 3 group (100% jobs). At the same time, according to the request for medical care, employees were diagnosed with isolated cases of occupational diseases.The levels of morbidity with temporary disability of employees of the main workshops are statistically significant (p<0.05) higher than those of the control group in 1.4–1.9 times. The influence of the complex of chemical factors of low and medium intensity on the levels of morbidity of respiratory diseases in the group of workers of the wagon wheel workshop, which were 1.7–2.0 times higher than in the control group, is confirmed by the average degree of causation of the production condition of this pathology (RR=1.7; EF=42.0%).The combined effect of vibration and severity of the labor process forms a high level of temporary disability of employees of the main workshops in connection with diseases of the musculoskeletal system, which was 2.7–4.4 times higher than in the control group, and also determines the prevalence of this pathology in the structure of diseases detected on medical examinations (23.2%). Diseases of the musculoskeletal system are caused by the production of employees of the wagon meintenance workshop (RR=3,9; EF=74,9%), as the most unfavorable in terms of hygiene on these factors.The stressful influence of the complex of harmful production factors on the health of wagon repair workers is manifested by the high risk of diseases of the cardiovascular system, gastrointestinal tract, neurological disorders, violation of adaptation of the cardiovascular system in 97% of the examined, as well as the predominance of diseases of the digestive system and circulatory system detected on periodic medical examinations.Conclusions. Harmful working conditions (class 3.1–3.4) cause the suspected occupational risk from small (moderate) to very high (intolerable) to 100% of the jobs of wagon repair workers. The results of the study of morbidity and risk of pathology indicate a significant risk of damage to the health of workers.

The presented study addresses the problems of development of small and medium towns in Russia. Aim. The study aims to examine a town as a socio-economic environment where its residents exist and as the fundamental factor for the development of society.Tasks. The authors identify key problems in the development of small and medium Russian towns, which interferes with the historical appearance and has a negative impact on the living environment.Methods. Problems in the development of small and medium towns in Russia are examined using theoretical methods: systematic approach, statistical analysis, social and philosophical analysis.Results. The study identifies the main negative effects of the existing model of development of small and medium Russian towns, such as destruction of their historical and cultural appearance, distortion of the overall architectural motif, increased load on communications, and congestion of the transport infrastructure.Conclusions. At the current stage, efficient development of small and medium towns in Russia is impossible within the framework of the existing infill development. This chaotic process cannot be stopped without a new conceptual approach and changes in the legislative and normative framework of urban development. The only factor that determines the boundaries of the existing approach to urban development is the lack of physical space for new buildings in urban areas. The authors formulate proposals that would help to solve the problems of development of small and medium towns in Russia.

Abstract Background Many studies have shown that psychosocial work stressors have a negative impact on health. It is therefore important to understand how psychosocial work stressors can be reduced. First cross-sectional studies have shown that working conditions are influenced at the political level. With this study, we want to extend the existing studies by specifically looking at the longitudinal dimension and test if changing labour market policies are related to changes in psychosocial work stressors. Methods We used comparative longitudinal survey data from the European Working Conditions Survey (27 countries; years 2005, 2010, 2015). The measure of psychosocial work stressors is based on two established work stress models: job strain and effort-reward imbalance. To measure labour market policies we used information on active (ALMP) and passive labour market policies (PLMP). 64659 participants were eligible for the ERI analysis and 67114 participants for the analyses on job strain. Estimation results are provided by three-level multilevel regressions. Results An increase in ALMP investments lead to a decrease of ERI and therefore to an improvement in psychosocial working conditions. The analyses for the subcomponents showed that these results are mainly driven by reward: an increase in ALMP investments lead to an increase in rewards. We didn't find significant associations between ALMP and job strain and between a change in PLMP measures and the observed work stressors. Discussion The study extends current knowledge with longitudinal information by showing that an increase in ALMP lead to an increase in rewards and a decrease of ERI. These longitudinal analyses are more closely related to a causal interpretation than previous cross-country analyses. The findings of this study may have important policy implications. Our main result suggests that investments into ALMP can improve certain working conditions and therefore improve workers' health. Key messages Psychosocial work stressors have a negative impact on health. Investments into active labour market policies can improve psychosocial working conditions.

AbstractThe 2011 National Nutrition Survey of Pakistan revealed that 51% of the country’s population was consuming less than 2,100 calories a day. In the backdrop of rising food insecurity, hunger, and malnutrition in Pakistan, this study aims to measure the effects of indirect taxation on health outcomes of children (<5 years). More specifically, the impact of the incidence of General Sales Tax (GST) in the province of Punjab has been estimated on a child’s height and weight. The proponents of the uniform GST argue that the tax would not affect children because most food items consumed by children are exempted from the GST. However, the opponents believe that households, especially those belonging to the lower-income group, would reallocate resources away from children in the face of higher GST. To study these effects, we utilized three different waves (2007–08, 2011 & 2014) of Multiple Indicators Cluster Surveys (MICS). The results show that the tax incidence, and not the GST rate, has a significantly negative impact on children’s height-for-age Z-score (HAZ). No effect was found on the weight-for-age-z-score (WAZ). These results are robust to different specifications and exhibit considerable heterogeneity across different income groups. These findings suggest that the exemption of certain food items for children from the GST may not eliminate the negative effects of this tax on a child’s health. Thus, our study raises concerns about the long term welfare consequences of GST.

Abstract Purpose We conducted a retrospective observational study in order to identify negative effects of NOTES procedures (Natural Orifice Transluminal Endoscopic Surgery) with transvaginal specimen removal on pregnancy and delivery. Methods From the total population of 299 patients in our NOTES registry, we tried to contact the 121 patients who were of reproductive age (≤ 45 years) at the time of a transvaginal NOTES procedure. They were interviewed by telephone regarding their desire for children, post NOTES-operation pregnancies, and type of delivery using a structured questionnaire. The collected data was analyzed and compared with current data. Results We were able to contact 76 patients (follow-up rate: 62.8%) with a median follow-up of 77 months after surgery (33–129 months). Twenty of 74 participating patients had a desire for children (27.0%). One of them and another's male partner were diagnosed as infertile. Regarding the remaining 18 patients, 14 became pregnant, and three of them became pregnant twice. Considering these 17 pregnancies, there was one miscarriage (5.9%) and one twin birth (5.9%). On average, childbirth occurred 44 months after the NOTES procedure. With regard to the type of delivery, 10 vaginal births (58.8%) and 7 caesarean sections (41.2%) occurred. Thus, the rate of fulfilled desire for children was 77.8%. Compared with the literature, no difference to the normal course could be detected. Conclusion There is no sign that the transvaginal approach in Hybrid-NOTES, with removal of the specimen through the vagina, has a negative effect on conception, the course during pregnancy, or the type of delivery.

The following research focuses on the possibility of applying fresh plant material as a carrot pulp to supplement newly developed extruded products in the form of pellets and microwave-expanded snacks. Fresh carrot pulp, as a valuable vegetable ingredient, was used in the amount of 2.5 g/100 g to 30.0 g/100 g in a potato-based recipe. The snack pellets were processed via extrusion-cooking, using a single-screw extruder with a plasticizing unit L/D = 18, and the use of variable screw speeds. The produced pellets underwent microwave expansion to limit the fat content, so as to produce ready-to-eat (RTE) snacks. The pellets and snacks were tested for nutritional value, as well as for selected quality features: physical properties, structure, pasting characteristics, and texture profile, and PCA analysis and a correlation matrix were performed on the obtained results. Microwave expansion of pellets increased the total phenolic content, the antioxidant activity, water absorption index and lightness of snacks, but decreased the bulk density and setback values of the expanded products when compared to pellets. Generally, we found that it was possible to use up to 30.0 g/100 g of fresh carrot pulp with a positive effect on nutritional value, and without negative effects on the physical properties of extruded products. Both the extrusion-cooking and microwave expansion can minimize the negative impact on plant materials, due to the short processing time.

AbstractThis paper addresses theoretically the question how virtual communication may affect cooperation in work teams. The degree of team virtualization, i.e. the extent to which interaction between team members occurs online, is related to parameters of the exchange. First, it is assumed that in online interaction task uncertainties are higher than in face-to-face contacts. Second, the gratifying value of peer rewards is assumed to be lower in online contacts. Thirdly, it is assumed that teams are different in the extent to which members depend on their peers for positive affections, operationalized by the extent to which team members are interested in social relationships for their own sake, independently from their work interactions. Simulation results suggest both positive and negative effects of team virtualization on work-cooperation.
