When growing crop products, it is important to use an integrated approach at the stages of planning technological operations and developing technical means for their implementation. In this case, the best result is achieved when coordinating operations on mechanical and chemical tillage, which provides for the protection and nutrition of plants. Along with this, it is important to consider following the applied technology to environmental principles, since agriculture directly affects the environment of our planet. Resource-saving technologies help preserve nature for future generations, restore natural fertility and take care of economic well-being. For row crops, the use of Strip-till technology is recommended. This requires 20...30% of all costs to direct to chemical treatment. Obviously, a decrease in the chemical effect on the soil during the transition to strip technology is necessary, and the introduced chemical should be redirected strictly to the target. A technical solution for the adaptation of serial sprayers is proposed, which consists of the use of strip spraying with the ability to accurately add and redistribute the working solution to the objects of influence, considering stage of plant development. This allows to reduce hectare application rates and stress of cultivated plants, and to save money on chemical processing. In addition, it also helps to solve environmental problems by reducing the chemical load on the soil. The proposed approach and technical solution make it possible to supplement the complex of machines for mechanical tillage in the framework of strip technology and reduce the chemical load on the biosphere.

Abstract To preserve and restore disturbed lands and reduce the damaging impact on air, plants and soil, it is necessary to apply resource-saving technologies. Strip-till technology is recommended for tilled crops. The technical solution is offered to increase the efficiency of the working solution use due to the rational distribution on the objects of influence and increase of its uniformity. That is, it is possible to reduce the hectare rate of consumption of the working solution by using the method of strip chemical treatment of plants. This is achieved by the redistribution of the working solution between the row and the row with the cultivated plant. The technical solution is to equip the serial sprayer with two lines with spray nozzles and special separator bodies. After a quick changeover in the field without the use of special tools, it is possible to switch from continuous spraying to strip spraying and back. At switching over to strip spraying, the spray solution is sprayed strictly along the strips of cultivated plant growth and covers the whole surface of stem and leaves. This allows reducing the cost of liquid chemicalization agents application and accurately redistributing the working solution.

The progress made in dentistry during the latest decades is due, conceptually, to the new, systemic vision of man, which has also taken place in this field of medicine. In this context, the link between organic and psychic is indestructible. Thus illness is understood as a drama in which the somatic process has a psychic value, and the mental one has a body value. It is known that the morphological and functional integrity of the dental system, health and vigorousness, gives the individual a state of well-being that affects his somatic and psychic health, as any disturbance at this level entails repercussions in psychological and social behavior. Such a disruption is the total edification that seriously alters not only the dental system but the whole organism, putting various biological and psychosocial problems to the practitioner. The total expression represents not only a physical disability but also a psychological one. A special importance in studying psychological changes at total edentulous presents the psychological aspects of senile involution. This is not only a theoretical but also a practical importance due to the increase in the number of elderly people. Through the researches of the present paper we intend to present the reality of the psychological manifestations in the total edentation, which is objectified on different methods of psychodiagnosis in the first part, in order for the second part to be addressed to problems of prosthetic psychotherapy.The study comprises a group of 43 patients, of whom 24 were men and 19 women with total uni or bimaxilar edentation. Total edentation can be and is responsible for somatopsychic alterations, along with other pathogens, general, local, social, which sometimes can take a dramatic form, converting, where the area is also favorable, a pure somatic disease, for those who are not in psychopathy or even psychosis, although these latter cases are extremely rare and especially in youngsters, which would disrupt not only the person�s behavior as an individual, but also their status, function and social integrity. The treatment of dental and psychological complex is mandatory for any patient, but especially for the elderly, where recovery is more difficult, with disease-specific disorders adding to those of senescence.

In public policy scholarship on policy design, emotions are still treated as opposed to goals, and their presence is assumed to signal that things have gone wrong. We argue, however, that understanding how and for whom emotions matter is vital to the dynamics of policy designs because emotions are central to the capacity building of policy intermediaries and, with that, to the success of public policies. We examine the case of Czech single mothers in their role as intermediaries in ‘alimony policy’. Our interpretive survey provided single mothers an opportunity to express the way they experience the policy emotionally. The analysis reveals that the policy goal of the child’s well-being is produced at the cost of the mother’s emotional tensions and that policy designs defuse these emotional tensions, implicitly. These contradictory emotions expressed by mothers show us a gateway to problematising policy designs in a novel way, which reconsiders construing policy design as a technical, solution-oriented enterprise to one in which emotional tensions intervene in policy design and are essential for succeeding.

The global disconnect between the Sustainable Development Goals (SDGs) and the Convention on the Rights of the Child (CRC), has been described as ‘a missed opportunity’. Since devolution, the Welsh Government has actively pursued a ‘sustainable development’ and a ‘children’s rights’ agenda. However, until recently, these separate agendas also did not contribute to each other, although they culminated in two radical and innovative pieces of legislation; the Rights of Children and Young Persons (Wales) Measure (2013) and the Well-being and Future Generations (Wales) Act (2015). This article offers a case study that draws upon the SDGs and the CRC and considers how recent guidance to Welsh public bodies for implementation attempts to contribute to a more integrated approach. It suggests that successful integration requires recognition of the importance of including children in deliberative processes, using both formal mechanisms, such as local authority youth forums, pupil councils and a national youth parliament, and informal mechanisms, such as child-led research, that enable children to initiate and influence sustainable change.

The pandemic caused by COVID-19 has left few countries untouched. It is a far-reaching implication on humankind, with children and adolescents, being no exception. Although the prevalence and fatality are negligible among children, a possible impact on their psychological and mental health cannot be disregarded. The unprecedented change in the way of living is bound to be having some psychological consequences on children and adolescents. The experiences gathered in childhood and adolescence are known to contribute to shaping the physical, emotional, and social well-being in adult life. Children are highly susceptible to environmental stressors. The present situation has the potential of adversely affecting the physical and mental well-being of children. To save the children from the long term consequences of this pandemic, a holistic approach integrating biological, psychological, social and spiritual methods of enhancing mental health have become essential. A concerted effort of government, Non Government Organisations (NGOs), parents, teachers, schools, psychologists, counselors and physicians are required to deal with the mental health issues of children and adolescents. This paper discusses the possible role of these agencies in the holistic intervention of this crisis.

In order to prepare soil for sowing of agricultural crops it is necessary to have a number of engineering structures that ensure its qualitative treatment and protection from erosion. Modern equipment do not fully meet the whole complex of specified requirements. Application of tillage machinery being used for main soil cultivation is directed on suppression (destruction) of natural vegetation which is considered as the strongest competitor to cultivated plants. From the other side, vegetation on the Earth’s surface plays an important role for reliable protection of soil from erosion. Destruction of vegetation throughout the whole period of crop tending leads to the fact that the remaining cultivated plants are not able to protect soil from erosion by such natural aggressive factors as rain storms and strong winds. As a consequence, processes of soil structure destruction and losses of entire soil strata and its fertility occur in the geographical (landscape) envelope. Thus, equipment for primary and secondary soil tillage exerts double impact: from one side, killing of weeds takes place, and on the other hand, there is destruction (erosion) of soil structure and profiles of its geographical envelope. The soil, in the understanding of the earth, is the perfect place that gives life to plants and organisms, has a fertility. For the last 50 years analytical scope of physical processes occurring in the soil has been extended, physical methods for investigation of soil properties and application of technical equipment for assessment of physical-mechanical soil characteristics have got widespread use. However, there is no summative investigation on soil physics which includes and reveals thermodynamics, electrophysics and nuclear physics of soils. At the same time an integrated approach for studying such complicated object makes it possible to understand important nature of some processes occurring in the soil and to develop practical measures for fertility improvement and erosion reduction. The paper considers problems pertaining to deformation mechanism while forming soil structure and its compression under influence of external loadings: magnetic, electric, physico-chemical, gravitational and thermal fields and working organs of tillage tools.

Internal branding is considered as an Human Resource (HR) construct for creating, implementing and measuring the employee-based brand image in organizations. The purpose of this study was to empirically analyse the influence of internal branding initiatives on overall workplace well-being in which every stakeholder feels included, valued and respected. A study conducted on a sample of 443 respondents across four different Indian services sector examined how internal branding strategies help in psychological, physical, spiritual, financial and social well-being of employees. A conceptual framework based on the hypotheses was tested to establish correlations among internal branding, employee well-being and employee-based brand outcomes at individual and organizational levels. It shows that internal branding is an integral part of overall well-being programme and supports individual and organizational outcomes. Organizations can use this framework to improve their well-being strategies based on their internal brand creation process and also benefit from the increased organizational effectiveness.

It is common practice to use theoretical frameworks developed in the West for education worldwide, but important contributions come as well from non-Western education perspectives that shed light on the emergence of ideas within given regional diasporas. Value creation serves as a valuable lens through which to examine the ideas and relevance of three thinkers from the Indian subcontinent—the Buddha (6th or 5th century bce), Rabindranath Tagore (1861–1941), and Mahatma Gandhi (1869–1948). The term “value creation” encompasses a Japanese approach to curriculum (based on the work of Tsunesaburo Makiguchi, 1871–1944) that is founded on an interdependent view of life and aimed at developing learners’ capacity to enhance their own existence and contribute to the well-being of others. Using value creation as a lens to examine the contributions of the Buddha, Tagore, and Gandhi can allow for a discourse on the indigenous nature of their respective ideas that are rooted in Eastern philosophies based on similar interdependent worldviews. The emergence of alternative curricular in the Indian diaspora that are based on such interdependent worldviews, offer an integrated approach to education. A value-creating framework can be useful to examine the Indian educational scene and the many attempts that have been made for the individual learner to be the focus of education.
