The Subject of the Study. The article deals with an issue of impact of atypical employment on the socioeconomic development on micro- and macro levels. The Purpose of the Study is to discover the links between the introduction of atypical forms of employment and socioeconomic development. The Main Theoretical and Empirical Aspects of Study: as the implementation of various forms of atypical employment is one of the aspects of flexibility in employment relations’ regulation, the author starts with a general analysis of impact of general flexibility of employment on the economy. This section of the article contains the conclusion that a thesis about positive effect of labour law flexibility on the economic effectiveness remains unproven; – the second part of the article contains an analysis of the relations between the specific forms of atypical employment and the state of economy. The conclusion has been made that ill-considered implementation of such forms into the labour legislation leads to such negative consequences to the economy as the labour market segmentation and volatility, rising incomes gap and lowering the purchasing power. – the thesis is made that Russian labour legislation modification in the field of atypical employment development is only acceptable with a view to make the already existing atypical employment come out of informal sector, and in a way that takes into account the interests of both parties of the employment relationship.

Abstract It has been demonstrated that a uniform relationship between input actuation velocity and output manipulator velocity, i.e., a constant dexterity, over the workspace is desirable. When a manipulator demonstrates the desired uniformity in dexterity, the level or magnitude of dexterity for a given task is easily selected through a constant gearing ratio applied between the actuators and manipulator input. However, many of the manipulator architectures commonly used in robotic systems lack uniformity in dexterity over their available workspace. This results in a large variation in input motor speed when trying to perform a constant output velocity task, as well as a loss in fidelity of motion or response speed over the workspace. Additionally, a large variation in required input torque occurs when traversing a path with constant payload. This paper proposes a means of improving the uniformity of dexterity (input to output velocity or force ratio) of non-dexterous manipulator devices, such as the serial pitch-yaw wrist, through the application of nonlinear transmission elements located between the actuators and the manipulator input joints. The proposed method is presented for application to general manipulator systems.

Positive Effect

Small-plot field trials monitored the effect of drip irrigation of potatoes on tuber and starch yield. The trials were performed at two different localities in two trial years, 2016 and 2017. The subject of the evaluation included two cultivars with different vegetation periods (the very early cv. Monika and the semi-early cv. Jolana). Four repeated trials studied 4 irrigation treatments according to the available water capacity (AWC) of the soil, i.e. without irrigation, irrigation when soil humidity decreased below 60, 65 and below 70% AWC. All monitored parameters reflected a positive effect of irrigation in comparison to the non-irrigated control. The Žabčice locality showed the highest tuber and starch yields mostly after medium-intensity irrigation. The Valečov locality achieved the highest tuber and starch yields after the highest-intensity irrigation. Subject to the locality and the cultivar, the recommendation is to introduce automatic irrigation start when the soil humidity drops to 65% AWC for heavy soils and 70% AWC for medium heavy soils.

Introduction Previous studies have shown teaching public health in medical courses improves students’ analytical, problem-solving and communication skills. However, little research to date has shown if public health teaching is helpful to paramedic students. The aim of this study was to examine if having paramedic tutors teach public health had a positive effect on students’ learning and interest in public health. Methods 184 second-year paramedic students at an Australian university completed a printed survey and provided feedback about their learning experience. Students answered multiple choice and open-ended questions about whether their understanding of a public health subject was improved by having a paramedic tutor, and if having different tutors each week affected students’ learning. Results Most students reported their understanding of public health improved when the subject was taught by a paramedic tutor and when paramedic scenario examples were included in teaching. Nearly half felt having different tutors each week made learning difficult. The following themes emerged from student narratives: the relevance of public health to their career; an improved understanding of public health; a realisation about the importance of public health; difficulties presented by an inconsistent teaching style; and poor follow-up and conflicting advice. Conclusion Teaching public health from a paramedic perspective enabled students to understand the relevance of paramedic practice and the role paramedics play in the public health system. Having the same paramedic tutor teaching each week helped students understand the relationship between public health and paramedic practice.

Teachers in schools are the subject of research by taking a sample of 180 teachers, using the proportional random sampling technique, and using questionnaires about the implementation of educational supervision by the school principal and the results of the teacher performance assessment data that the school has. And from the research and assessment it can be seen that the implementation of supervision of education by the principal does not have a positive effect on teacher performance and the implementation of supervision of education by the principal is also a weak influence and even very weak towards the performance of teachers in schools.

TEIXEIRA, M.E. e PEREIRA, J.L. Importância da preparação física para o paciente com doença de Parkinson. Revista Científica JOPEF, Vol.28, n.1, pp.29-43, 2019. Parkinson's disease (PD) is a chronic progressive neurodegenerative disease described by the first in 1897 as "tremor paralysis." Its symptoms are variable, the most characteristic being tremor of the hands and loss of balance and muscular strength. It usually affects men over the age of 60, but there are forms that can occur in younger individuals. The progression of symptoms causes the quality of life of the patient to deteriorate significantly, leading to the inability to perform daily activities. In addition to pharmacological treatment, physical exercise has been indicated as a way to attenuate and slow the progression of symptoms. The objective of this work is to carry out an integrative review of literature on the subject, in which articles published over the last 10 years have been analyzed, thus seeking to update the theme. In general, it was possible to perceive a positive effect of the practice of specific physical exercise programs in patients with PD, with improvement of the quality of life. In vitro studies also demonstrated the protective effect of physical exercise on the onset of the disease. Keywords: Parkinson's disease; Physical exercise; Neuroprotection; Quality of life.
