In the contemporaries of the Coronavirus Pandemic, the working from home was adopted as a health prevention measure. This article aims to analyze the ergonomic, emotional, and psychological aspects arising from this new way of working with professors of the Production Engineering Department of the Federal University of Amazonas - UFAM. The study is descriptive and was elaborated by literature review, and data survey through online interviews. The participants answered a questionnaire in which it was verified the points that directly interfere in the quality of life and performance of the professors in their professional activities. According to the results obtained, it was found that the reality faced by the workers is divergent from the standards established by ergonomic norms. It was also observed that the sharing of personal and professional life caused worries, stress, and anxiety, impacting on the educators' emotional health. Finally, we recommended possible solutions to mitigate the negative effects of this new way of working.

Abstract In recent decades, the number of birds reared per unit area has dramatically spiked to increase profitability in egg and meat production. However, nowadays, the increase in sensitivity to animal welfare and consumer demands brings along with it a raised interest in stocking density. Stocking density is defined either as the number of animals or body weight per unit area or as the area per animal. High stocking density, which is a stress factor, can be defined as an increase in the number of animals per unit area or a decrease in the area per animal. Stress caused by high stocking density negatively affects the bird’s physiology and performance as well as the quality of the product obtained. The ideal stocking density should be 9 laying hens, 35 kilogrammes for broilers, and 45 quails per square metre. Otherwise, one will observe stress indicators in birds reared in more than the recommended stocking density per unit area and, consequently, a decrease in bird growth, egg production, feed efficiency, and egg or meat quality. Apart from increasing the concentrations of amino acids such as lysine, methionine, tryptophan and arginine, minerals such as selenium and chromium, and vitamins such as C and E in the diet, the addition of additives such as probiotics, humates, phytophenol compounds, and propolis is also effective in reducing or eliminating these negative effects caused by high stocking density. As a result, regulations in the nutrition of animals are effective in reducing/preventing such negative effects, thus improving animal welfare and ensuring the maintenance of optimum yield.

This article investigates the possible negative effects of power in organizations. It demonstrates how holding power may affect an individual’s perception of others, actions, and cognition. Ways in which power may have a detrimental effect on different aspects of a manager’s functioning within an organization, including building relationships, communication, and performance are analyzed. It is argued that individuals are unaware of these effects, and thus it is necessary to introduce methods of their diagnosis and countermeasures on the organizational level. In addition, negative phenomena associated with the power’s distribution among organizations’ units and its structural aspects are analyzed. A set of questions is proposed, which can be used by individuals and organizations to reveal the extent to which adverse effects of power are present in an organization. These inquiries can be used to design and introduce specific countermeasures and improve communications and the quality of interactions within organizations. Selected countermeasures are also proposed in the article.

The aim of this study is to review the quality and types of the litter material and its effect on the welfare and performance of the broiler chickens. Since the most suitable broiler rearing system is on the littered floor, the litter material is of great importance. Demand for litter material is also increasing, depending on the development in broiler production. Straws, wood shavings, and sawdust are widely used as litters material. Beside these, materials such as wheat, barley, rye, oats, sunflower, rice, hazelnut, maize, soya, peanut, cotton and sugarcane are used purely or mixed as a litters material. The quality of the litter is determined with the litter moisture, pH, ammonium nitrate content, caking level and water holding capacity. The ideal litter material should have a moisture content of 20-25%, a pH of 8-10, and ammonia content should not exceed 25 ppm. The thickness of the litter changes between 2 and 10 cm according to the type of the litter, and size of it should not exceed 0.6 cm. Increase in the litter moisture increases pH, NH3 concentration and caking. The type of litter material effects on the performance, welfare, health, behavior and product quality of broiler chickens. In addition, there are negative effects of litter materials on carcass defects, foot-leg problems, breast blisters or bruises, decrease in living power, and increase of microorganism development due to litter moisture, increase of gas and dust formation in poultry. These adverse effects cause large economic losses in intensive enterprises. For this reason, the quality and type of litter material is very important in broiler rearing.

Physical education teacher, as a profession, has various duties, which impact teacher's physical and emotional health. This may have an effect on quality of lessons. The aim of the research is to establish the self-evaluation of PE teachers' health. The following indicators of health self-evaluation were chosen: taking care of one's health, health condition and its evaluation. Questionnaires were used to self-evaluate PE teachers' health, to point out diseases such as having a cold, also various somatic and psychosomatic disorders. The sample of the research was 324 PE teachers, randomly chosen from high schools in Lithuania. The average age of the participants was 44,59 ± 0,57 years old, their pedagogical work experience - 20,52 ± 0,58 years. It was found that only 29,1 per cent of female and 18,3 per cent of male participants rated their health as good. Teachers who evaluated their health positively more seldom experienced various somatic and psychosomatic disorders. Teachers with more than 20 years of work experience rarely evaluated their health as good. In addition, they more frequently experienced various disorders.Women, when compared to men, are more prone to health disorders. Furthermore, women with more than 20 years of work experience more rarely fell into the group of long-term somatic and psychosomatic disorders.

Introdução: O alongamento muscular é uma prática popularmente realizada com o propósito de melhorar a qualidade de vida e o desempenho em atividades físicas. Alguns estudos científicos relatam efeitos deletérios desta prática relacionadas às respostas mecânicas e neurais para a realização do movimento, os quais poderiam ser diretamente interferentes em variáveis como o tempo de reação manual (TRM), visto que, rapidez e precisão nesta variável são fundamentais  em diversas atividades da vida diária, em algumas profissões e, especialmente, para o desempenho em exercício.Objetivo: O presente comentário teve por objetivo examinar e discutir o efeito das diferentes técnicas e volumes de alongamento muscular sobre o TRM e suas consequências.Conclusão: O baixo volume de alongamento (≤ 30s), independentemente da técnica ou intensidade, não interfere sobre o TRM. Face ao que se apresenta na literatura sobre o tema, não é possível realizar julgamento conclusivo da associação de alto volume de alongamento (duração > 30s) com a resposta motora manual. Adicionalmente, é imperativo estudos que objetivem avaliar o efeito do alongamento sobre o TRM, em mulheres ou associado ao dimorfismo sexual.Influence of Muscle Stretching on Hand Reaction TimeIntroduction: Muscle stretching is a popular practice with the purpose of improving quality of life and performance in physical activities, although some scientific studies report negative effects related to mechanical and neural responses to the movement, which could directly interfere in variables such as hand reaction time (HRT). Since, speed and precision in this variable are fundamental in several activities of daily living, in some professions, and especially for performance in exercise.Objective: This commentary aims to examine the state of the art on the effect of different techniques and volumes of muscle stretching on HRT and its consequences.Conclusion: Literature suggests that stretching volume (≤ 30s), regardless of technique or intensity, is not able to interfere on HRT. On the other hand, it´s not possible to make a conclusive judgment on whether high stretching volume (> 30s) is able to compromise hand motor response. Additionally, other studies are imperative to evaluate the stretching effect on HRT for women, or its association to sexual dimorphism.

Abstract. The positive effects of goal setting on motivation and performance are among the most established findings of industrial–organizational psychology. Accordingly, goal setting is a common management technique. Lately, however, potential negative effects of goal-setting, for example, on unethical behavior, are increasingly being discussed. This research replicates and extends a laboratory experiment conducted in the United States. In one of three goal conditions (do-your-best goals, consistently high goals, increasingly high goals), 101 participants worked on a search task in five rounds. Half of them (transparency yes/no) were informed at the outset about goal development. We did not find the expected effects on unethical behavior but medium-to-large effects on subjective variables: Perceived fairness of goals and goal commitment were least favorable in the increasing-goal condition, particularly in later goal rounds. Results indicate that when designing goal-setting interventions, organizations may consider potential undesirable long-term effects.

The article considers the role of trust in the economy, the mechanisms of its accumulation and the possibility of using it as one of the growth factors in the future. The advantages and disadvantages of measuring the level of generalized trust using two alternative questions — about trusting people in general and trusting strangers — are analyzed. The results of the analysis of dynamics of the level of generalized trust among Russian youth, obtained within the study of the Institute for National Projects in 10 regions of Russia, are presented. It is shown that there are no significant changes in trust in people in general during the study at university. At the same time, the level of trust in strangers falls, which can negatively affect the level of trust in the country as a whole, and as a result have negative effects on the development of the economy in the future. Possible causes of the observed trends and the role of universities are discussed. Also the question about the connection between the level of education and generalized trust in countries with different quality of the institutional environment is raised.

Lighting is one of the key elements in any space and building infrastructure. Good design for an area in the building requires sufficient light that contributes to the efficiency of the activities. The correct method allows natural light to transmit, reduce heat and glare in providing a conducive learning environment. Light plays a significant influence to the quality of space and contributes focus of the students in an architecture studio. Previous research has shown that the effect of light also controlled emotions, behavior, and mood of the students. The operations of artificial lighting that have been used most of the time in an architecture studio during day and night may create lavishness and inadequacy at the same time. Therefore, this paper focuses on the identifying the quality of light for the architecture studio in UiTM (Perak), to instill a creative learning environment. Several methodologies adopted in this study such as illuminance level measurement using lux meter (LM-8100), and a questionnaire survey in gauging the lighting comfort level from students’ perspective. The study revealed that the illuminance level in the architecture studio is insufficient and not in the acceptable range stated in the Malaysian: Standards 1525:2007 and  not evenly distributed.  The study also concluded that the current studio environment is not condusive and appears monotonous.

Background.Question about the quality and format of postgraduate education of doctors raises increasingly in recent years. Development of professional standards and transition to a system of continuing professional education have allowed professional communities to raise issues of the quality of modern education but there is no clear evidence of the dependence of the level of education and the quality of medical care in the accessible literature. Experts of Research and Practical Center of Medical Radiology carried out the identification of dependence of post-graduate education length for radiologists and the quality of their work that can serve as a rationale for amending the system of doctors training.Patients and methods.The data on education and actual work of 85 radiologists of out-patient and in-patient units of medical organizations of the Moscow Healthcare Department have been analyzed. According to the results of the audit of diagnostic studies, carried out in the “Unified Radiological Information Service” system by the specialists of the Research and Practical Center of Medical Radiology, the final assessment of the work of each radiologist was formed, which reflects the presence or absence of diagnostic discrepancies.Results.Parameters of diagnostic errors depending on the age of doctors, the general length of service and the length of service as radiologist, the duration of postgraduate education in the clinical specialty and the specialty “radiology” have been compared.As a result of the analysis, it was found that the increase in the proportion of diagnostic differences is directly related to the increase in the age of the doctor and does not depend on either the length of service or the time of work in the specialty. Differences between the groups of physicians with the largest (professional retraining after clinical residency) and the smallest (clinical education + radiology) percentage of clinically significant discrepancies are statistically significant (p = 0.05, at the normative value of the Student's test score of 2.16).Conclusion.The inverse relationship between the duration of training of the radiologist in the specialty and the proportion of diagnostic errors, which can serve as a significant justification for making proposals for the exclusion of professional retraining within 576 hours for admission to professional activities of radiologists.

Subject. The article reviews the way strategic threats to energy security influence the quality of people's life. Objectives. The study unfolds the theory of analyzing strategic threats to energy security by covering the matter of quality of people's life. Methods. To analyze the way strategic threats to energy security spread across cross-sectoral commodity and production chains and influences quality of people's living, I applied the factor analysis and general scientific methods of analysis and synthesis. Results. I suggest interpreting strategic threats to energy security as risks of people's quality of life due to a reduction in the volume of energy supply. I identified mechanisms reflecting how the fuel and energy complex and its development influence the quality of people's life. The article sets out the method to assess such quality-of-life risks arising from strategic threats to energy security. Conclusions and Relevance. In the current geopolitical situation, strategic threats to energy security cause long-standing adverse consequences for the quality of people's life. If strategic threats to energy security are further construed as risk of quality of people's life, this will facilitate the preparation and performance of a more effective governmental policy on energy, which will subsequently raise the economic well-being of people.
