Hydrocarbons, especially aromatic volatile organic compounds (AVOCs) and polyaromatic hydrocarbons (PAHs), emitted by IC engines, indisputably have a negative impact on the environment and public health. Even though current legislation strongly impacts on their low concentration in the exhausts, not quantity but the quality of those substances determines fumes toxicity. The paper presents results of the researches on a photocatalytic device dedicated to BTX (benzene-toluene-xylene) removal from IC engine exhausts, which can be applied in a vehicle cabin ventilation system. According to the results, the system is able to decrease toxic compounds concentration (caused by mobile emission sources) in inlet-air delivered to the vehicle interior. In effect, the system application reduces the users of a vehicle to exposure on contaminants.

Tract Infections

Инфекции мочевых путей - наиболее распространённая группа заболеваний в практике врача уролога. Один из представителей является хронический рецидивирующий бактериальный цистит. Данное заболевание встречается во всех возрастных категориях и затрагивает все сферы жизни пациентов. Симптомы, возникающие при обострении хронического бактериального цистита, оказывают негативное влияние на качество жизни, что может приводить к нарушению психоэмоционального состояния больных. Отдельную группу высокого риска в отношении ИНМП составляют пациенты с нарушением углеводного обмена, у которых риск развития различных инфекций выше, чем у людей без подобных нарушений. К факторам, повышающим риск развития ИНМП у больных с нарушением углеводного обмена, относят возраст, компенсацию и наличие хронических осложнений, в первую очередь нефропатии и цистопатии. Человеческий организм функционирует циклически в соответствии с определенными индивидуальными ритмами. Любое хроническое заболевание приводит к рассогласованию процессов, протекающих в различных системах организма, вызывая развитие десинхроноза. Наличие у человека более 1 хронического заболевания утяжеляет течение болезни и приводит к снижению восстановительных способностей организма и сокращению его адаптационного потенциала Urinary tract Infections are the most common group of diseases in the practice of a urologist. One of the representatives is chronic recurrent bacterial cystitis. This disease occurs in all age categories and affects all areas of life of patients. Symptoms that occur with the exacerbation of chronic bacterial cystitis have a negative impact on the quality of life, which can lead to a violation of the psychoemotional state of patients. A separate high-risk group for INMP is patients with impaired carbohydrate metabolism, who have a higher risk of developing various infections than people without such disorders. Factors that increase the risk of developing INMP in patients with impaired carbohydrate metabolism include age, compensation, and the presence of chronic complications, primarily nephropathy and cystopathy. The human body functions cyclically in accordance with certain individual rhythms. Any chronic disease leads to misalignment of the processes occurring in various body systems, causing the development of DS, the Presence of more than 1 chronic disease complicates the course of disease and leads to a decrease in regenerative abilities of the organism and reduce its adaptive capacity

Decentralization Reform

An integral part of the implementation of any reform is the emergence of the risks of its negative impact on one or another area of region development. The decentralization reform in Ukraine is not an exception. In its the context the most probable occurrence of negative phenomena is in the border regions, which could be prevented by first detecting them. In the scientific article, the authors focus on the analysis of a number of challenges for the development of border regions in the context of decentralization reform. Given the territorial remoteness of the central regions of the country and the capital, which today serve as areas of concentration of investment and economic activity, the border regions traditionally (this is typical for the border areas of the EU member states) lag behind the rest of the regions by the main socio-economic indicators of development. Among the main challenges facing the border regions of Ukraine today are the following: the provision of competitiveness in the context of European integration processes and reduction of the border barrier function; low level of economic security; the outflow of human capital and the issue of ethnic minorities. Based on an expert survey of representatives of the fifteen united territorial communities (UTCs), the possibility of such risks of decentralization in the border regions were defined as following: groundless use of local budget funds; emergence of significant imbalances between delegated new authority and available financial resources of the community; increasing uneven development of territories within the community; increasing uneven development of communities within the country; deterioration of the availability and quality of providing educational and medical services; deterioration of the quality of local government; reducing of the state influence on the management of local development processes; radicalization of political unions representing the interests of ethnic minorities in places of their compact residence; further economic decline of the territory of communities and so on.

Perianal hyperhidrosis (HH) is a rare form of primary focal HH and may become a major problem for the patient with a significant psychosocial burden and negative impact on the quality of life. Botulinum toxin injections are widely used as a second-line treatment option for axillary, palmar, and plantar HH with a good safety profile. Herein, we pre­sent a case of primary perianal HH successfully treated with Botulinum toxin A at a dose higher than that previously reported in literature, with a longer response, a higher degree of satisfaction, and no adverse effects. Moreover, we review the main aspects of the perianal anatomy that are essential to carry out the technique correctly and make dermatologists achieve expertise with the procedure.

The disadvantage of aerostatic bearings is their low dynamic quality. The negative impact on the dynamic characteristics of the bearing is exerted by the volume of air contained in the bearing gap, pockets, and microgrooves located at the outlet of the feeding diaphragms. Reducing the volume of air in the flow path is a resource for increasing the dynamic quality of the aerostatic bearing. This article presents an improved design of an axial aerostatic bearing with simple diaphragms, an annular microgroove, and an elastic suspension of the movable center of the supporting disk. A mathematical model is presented and a methodology for calculating the static characteristics of a bearing and dynamic quality indicators is described. The calculations were carried out using dimensionless quantities, which made it possible to reduce the number of variable parameters. A new method for solving linearized and Laplace-transformed boundary value problems for transformants of air pressure dynamic functions in the bearing layer was applied, which made it possible to obtain a numerical solution of problems sufficient for practice accuracy. The optimization of the criteria for the dynamic quality of the bearing was carried out. It is shown that the use of an elastic suspension of the support center improves its dynamic characteristics by reducing the volume of compressed air in the bearing layer and choosing the optimal volume of the microgroove.

The aim of this study was to analyze athletes’ quality of life during the COVID-19 pandemic. The study involved 249 athletes between 15 and 35 of age, M = 21.22, SD = 5.12. The sample was composed of eight Olympic Games medalists, three European medalists, 67 international medalists, and 63 national medalists. The instruments used were: (1) COVID-19 Anxiety Scale, (2) Athlete Quality of Life Scale, (3) Impact of Pandemic on Athletes Questionnaire, and (4) International Personality Item Pool (IPIP Anxiety, Depression, and Vulnerability Scales). The results indicate significant differences in COVID-19 anxiety depending on the sport practiced, F (9239) = 3.81, p < 0.01, showing that there were significant differences between sports. The negative impact of the COVID-19 pandemic mediates the relationship between trait anxiety and the athletes’ quality of life. The percentage of mediation was 33.9%, and the indirect effect was −0.11, CI 95% (−0.18, −0.03), Z = −2.82, p < 0.01. Trait anxiety has an increasing effect on the intensity of the negative impact of the COVID-19 pandemic, 0.23, CI 95% (.10, 0.35), Z = 3.56, p < 0.01, and the negative impact of the COVID-19 pandemic has a decreasing effect on quality of life, −0.47, CI 95% (−0.67, −0.27), Z = −4.62, p < 0.01. Gender and age did not moderate the relationship between the negative impact of COVID-19 and athletes’ quality of life. The results of the study highlighted the impact that social isolation and quarantine have on athletes’ affective well-being.

The Impact

Abstract Scholars have long debated whether populism harms or improves the quality of democracy. This article contributes to this debate by focusing on the impact of populist parties in government. In particular, it inquires: (1) whether populists in government are more likely than non-populists to negatively affect the quality of democracies; (2) whether the role of populists in government matters; and (3) which type of populism is expected to negatively affect the quality of liberal-democratic regimes. The results find strong evidence that the role of populists in government affects several qualities of democracy. While robust, the findings related to (2) are less clear-cut than those pertaining to (1). Finally, regardless of their role in government, different types of populism have different impacts on the qualities of democracy. The results show that exclusionary populist parties in government tend to have more of a negative impact than other forms of populism.

Abstract This presentation describes a supportive mindfulness practice for caregivers of older adults based on the principles of Won Buddhism (an integrative, a modernized Buddhism). As the aging population grows, there is a significant increase in recognition of the negative impact of caregiver stress on older adults’ quality of life. The ability for caregivers to deal compassionately with stress is essential, as caring for older adults can awaken feelings about one’s own vulnerability and mortality. The ‘Mindful Gratitude Practice’ offers a way to cope with stress, cultivate self-care, and improve the care of others. Relevant research will be summarized, which shows mindfulness and gratitude practice respectively benefit positive influence in both physical and emotional well-being. Mindful Gratitude Practice as a spiritual approach that fosters caregivers' emotional stability, reduces their stress and improves the relationship between older adults and their caregivers. In this presentation, three processes of Mindful Gratitude Practice will be described: 1. Understanding a mindfulness practice by establishing intention, attention, and attitude, 2. Learning the principles of a gratitude practice and implementation, and 3. Incorporating mindfulness into a gratitude practice. Research results have demonstrated that through this learning process, caregivers have acquired the concept of interconnectedness, experience grateful moments, and a deep feeling of appreciation in their caregiving relationships. The presenter will guide participants in a short experience of Mindfulness Gratitude Practice. Further readings and resources will be provided for those who are interested.
