Marine traffic can be defined as the combination of individual ship movements in a specified area and the ‘quality’ of marine traffic depends in the first place on the human and technical quality of the vessels participating. The second important situation is in the rules and regulations by which the individual vessels are bound. In some areas these two conditions seem inadequate to guarantee an acceptable level of marine traffic safety. An adequate yardstick by which to measure this level of safety is however still lacking.

One of the requirements of our time is a high-quality public transport service for passengers. Reliability and regularity of traffic, duration and comfort of the trip, traffic safety, availability of equipped and convenient stops - all this and many other factors affect the quality of passenger service. The peculiarities of the organization of passenger transportation, as well as the performance of city routes, affect the psychophysiological state of a person and, as a result, the functional state and the degree of passenger fatigue, which leads to a decrease in his income. The study identified and analyzed the performance indicators of competing routes, which duplicate each other: bus route №276e and trolleybus route № 46. Based on the analysis of studies in the field of the quality of the provision of services by passenger transport, a survey form was formed on the quality of transportation on the routes of urban passenger transport. The assessment of the degree of consistency of experts' opinions using the Kendall coefficient of concordance indicates the consistency of expert opinions. Most of the criteria that were determined by passengers (interval of movement, the degree of filling and the service life of the vehicles) are indicators of the operation of the route, affect the passenger's transport fatigue and a decrease in the passenger's income. The change in the level of transport fatigue of the passenger during the waiting periods and at the end of the route trip in general along the directions of movement and on the individual hauls of the routs are determined. When assessing the quality of transport service on routes, the obtained values of transport fatigue indicate that when using routes, the condition of passengers is assessed as "good". But, if we consider the state of the passenger while using the individual hauls of the routes, his transport fatigue changes significantly and is assessed as "satisfactory". The value of a decrease in passenger income on routes increases throughout the trip, due to the dense filling of the vehicle interior, which negatively affects the functional state of the passenger. Under the existing conditions of passenger transportation on routes, the value of passenger fatigue and the value of passenger income reduction on bus route No. 276e exceeds the value of this indicator on the trolleybus route. To improve the organization of the bus route No. 276е, it is proposed to update vehicles and use buses with a larger passenger capacity (III class instead of I and II, which are used on the bus route now). After the implemented proposed measures for the busiest direction: the occupancy rate of the bus cabin decreased from 1,05 to 0,36, transport fatigue decreased from 5,5 points to 3,03 points, respectively, the value of the decrease in income from 60,55 UAH to 51,53 UAH. Updating vehicles on the Kharkiv bus routes are an urgent problem that requires an immediate solution to improve the quality of passenger transportation. The use of obsolete vehicles on city bus routes affects not only the passenger's fatigue, but also the drivers and, as a result, the likelihood of an road traffic accident. A significant adverse factor affecting the driver is the air pollution of the vehicle interior with harmful compounds, especially carbon monoxide.

In the residential area under the impact of emissions from non-ferrous metallurgy and woodworking industry, the quality of atmospheric air was shown to fail to meet the requirements of hygienic standards for the content of suspended solids in air [≤ 4 MPC for maximal single dose (MPCmsd), ≤ 12.5 MPC for average daily dose (MPCadd), phenol (≤ 5.6 MPCmsd, ≤ 4.83 MPCadd), formaldehyde (≤ 1.56 MPCmsd, ≤ 6.58 MPCadd), fluoride gaseous compounds (≤ 3.75 MPCmsd, ≤ 12.4 MPCadd), etc. The quality of potable water in the centralized water supply system from surface water source corresponds to hygienic standards but, and in drinking water from the underground water source hygienic standards of iron content are exceeded (up to 1.1 MPC, 3.6% of samples). Also, in the study area, exceedances of permissible concentrations in lead soils are observed up to 2.09 MAC (7.84% of samples) and fluorine up to 4.68 MPC (87.04% of samples). The individual carcinogenic risk for the children of the study area is, on average, 1.18 ∙ 10-3, for the adult population, an average of 5.25 ∙ 10-3, and exceeds the acceptable level of carcinogenic risk by about 52.5 times. The individual non-carcinogenic risk for the short-term exposure to chemicals is by up to 9 times higher than the acceptable level. The individual non-carcinogenic risk for the chronic multimodal intake of the studied chemicals exceeds the permissible value of the total hazard index by to 33.4 times with respect to respiratory disorders. Priority factors that determine the level of risk to public health are chemicals present in emissions from enterprises producing primary aluminum (Benz(a)pyrene, fluorides, sulfur dioxide, suspended substances) and cellulose (phenol, methyl mercaptan).

Techniques for three-dimensional reconstruction of macromolecular complexes from electron micrographs have been successfully used for many years. These include methods which take advantage of the natural symmetry properties of the structure (for example helical or icosahedral) as well as those that use single axis or other tilting geometries to reconstruct from a set of projection images. These techniques have traditionally relied on a very experienced operator to manually perform the often numerous and time consuming steps required to obtain the final reconstruction. While the guidance and oversight of an experienced and critical operator will always be an essential component of these techniques, recent advances in computer technology, microprocessor controlled microscopes and the availability of high quality CCD cameras have provided the means to automate many of the individual steps.During the acquisition of data automation provides benefits not only in terms of convenience and time saving but also in circumstances where manual procedures limit the quality of the final reconstruction.

If the customer is greater than acceptable level of service, the cutomer is not satisfied. Conversely, if an acceptable level of service greater than the expectations of customers, the customer will be satisfied. This means that if Bank BRI branch Fatmawati can improve service quality to its customer it will affect the level of satisfaction. In this research found evidence that, in terms of the creation of quality services, Bank BRI branch Fatmawati is one of the branches that participate to implement the established policies and service in accordance with the exiting service standard in the banking world. Amount of influence the determination of quality of service policies applied by the Bank BRI branch Fatmawati indicated by r2. r2 value only 45 % and the rest 55 % influenced by other variables not studied. Meanwhile, the variable relationship of service quality to customer satisfaction can be seen from the values r = 0,67. This shows the value of the correlation coefficient between the variables of service quality to customer satisfaction. This means there are strong relationships between the independent variable X (quality of service) to the dependent variable Y (customer satisfaction). Since r = 0,67 (67 %) greater then 50 %.

Greening of roads contributes to the protection of roads and their elements from influence of adverse weather and climatic factors; it includes the measures for improvement and landscaping of roads, ensures the protection of roadside areas from transport pollution, provides visual orientation of drivers. The solution of these issues will ensure creation and maintenance of safe and comfortable conditions for travelers. Green plantings in the right-of-way road area include woody, bushy, flower and grass vegetation of natural and artificial origin. For proper operation of public roads and satisfaction of other needs of the industry, there may be the need in removing the greenery. The reason for the removal of greenery in the right-of-way road area may be due to the following factors: construction of the architectural object, widening of the motor road, repair works in the security zone of overhead power lines, water supply, drainage, heating, telecommunications facilities, cutting of hazardous, dry and fautal trees, as well as self-grown and brushwood trees with a root neck diameter not exceeding 5 cm, elimination of the consequences of natural disasters and emergencies. The removal of plantations in the right-of-way area is executed in order to ensure traffic safety conditions and to improve the quality of plantations composition and their protective properties. Nowadays, in Ukraine there is no clear procedure for issuing permits for removing of such plantations. In order to resolve this issue, there is a need in determining the list of regulations in the area of forest resources of Ukraine and, if needed, the list of regulatory acts that have to be improved; to prepare a draft of the regulatory legal act that would establish the procedure of plantations cutting, the methodology of their condition determination, recovery costs determination, the features of cutting. Keywords: plantations, cutting, right-of-way, woodcutting permit, order.

This paper argues that the rise of what is commonly termed "personal religion" during the Classic-Hellenistic period is not the result of an inner need or even quality of the self, as often argued by those who see in ancient Greece foreshadowing of Christianity, but rather was the result of social, economic, and political conditions that made it possible for Hellenistic Greeks to redefine the perception of the individual and its relationship to others.

From a phenomenological perspective, the reflective quality of water has a visually dramatic impact, especially when combined with the light of celestial phenomena. However, the possible presence of water as a means for reflecting the sky is often undervalued when interpreting archaeoastronomical sites. From artificial water spaces, such as ditches, huacas and wells to natural ones such as rivers, lakes and puddles, water spaces add a layer of interacting reflections to landscapes. In the cosmological understanding of skyscapes and waterscapes, a cross-cultural metaphorical association between water spaces and the underworld is often revealed. In this research, water-skyscapes are explored through the practice of auto-ethnography and reflexive phenomenology. The mirroring of the sky in water opens up themes such as the continuity, delimitation and manipulation of sky phenomena on land: water spaces act as a continuation of the sky on earth; depending on water spaces’ spatial extension, selected celestial phenomena can be periodically reflected within architectures, so as to make the heavenly dimension easily accessible and a possible object of manipulation. Water-skyscapes appear as specular worlds, where water spaces are assumed to be doorways to the inner reality of the unconscious. The fluid properties of water have the visual effect of dissipating borders, of merging shapes, and, therefore, of dissolving identities; in the inner landscape, this process may represent symbolic death experiences and rituals of initiation, where the annihilation of the individual allows the creative process of a new life cycle. These contextually generalisable results aim to inspire new perspectives on sky-and-water related case studies and give value to the practice of reflexive phenomenology as crucial method of research.

Introduction: Individual and group level interventions have the largest effect on outcomes in patients with the first episode of psychosis. The quality of these individual and group level interventions provided to first-episode psychosis patients in Uganda is unclear.Methods: The study was performed at Butabika National Psychiatric Teaching and referral hospital in Uganda. A retrospective chart review of recently discharged adult in-patients with the first episode of psychosis was first performed to determine the proportion of participants who received the different essential components for individual and group level interventions. From the different proportions, the quality of the services across the individual and group interventions was determined using the first-Episode Psychosis Services Fidelity Scale (FEPS-FS). The FEPS-FS assigns a grade of 1-5 on a Likert scale depending on the proportion of patients received the different components of the intervention. Results: The final sample included 156 first-episode psychosis patients. The median age was 27 years [IOR (24-36)] with 55% of participants of the female gender. 13 essential components across the individual and group interventions were assessed and their quality quantified. All 13 essential components had poor quality with the range of scores on the FEPS-FS of 1-3. Only one essential component assessed (use of single antipsychotics) had moderate quality.Discussion: Among current services at the National psychiatric hospital of Uganda, the essential for individual and group level interventions for psychotic disorders are of low quality. Further studies are required on how the quality of these interventions can be improved.

The existing legislation determines the education as "an integral and focused process of teaching and upbringing, which represents a socially important value and shall be implemented so as to meet the interests of the individual, the family, the society and the state". However, even in this part, the meaning of the notion ‘socially significant benefit is not specified and allows for a wide range of interpretation [2]. Yet the more inconcrete is the answer to the question – "who and how should determine the interests of the individual, the family and even the state?" The national doctrine of education in the Russian Federation, which determined the goals of teaching and upbringing, the ways to attain them by means of the state policy regulating the field of education, the target achievements of the development of the educational system for the period up to 2025, approved by the Decree of the Government of the Russian Federation of October 4, 2000 #751, was abrogated by the Decree of the Government of the Russian Federation of March 29, 2014 #245 [7]. The new doctrine has not been developed so far. The RAE Academician A.B. Khutorsky believes that the absence of the national doctrine of education presents a threat to national security and a violation of the right of citizens to quality education. Accordingly, the teacher has to solve the problem of achieving the harmony of interests of the individual, the family, the society and the government on their own, which, however, judging by the officially published results, is the task that exceeds the abilities of the participants of the educational process.  The particular concern about the results of the patriotic upbringing served as a basis for the legislative initiative of the RF President V. V. Putin, who introduced the project of an amendment to the Law of RF "About Education of the Russian Federation" to the State Duma in 2020, regarding the quality of patriotic upbringing [3]. Patriotism, considered by the President of RF V. V. Putin as the only possible idea to unite the nation is "THE FEELING OF LOVE OF THE MOTHERLAND" and the readiness for every sacrifice and heroic deed for the sake of the interests of your Motherland. However, the practicing educators experience shortfalls in efficient methodologies of patriotic upbringing, which should let them bring up citizens, loving their Motherland more than themselves. The article is dedicated to solution to this problem based on the Value-sense paradigm of upbringing educational dynasty of the Kurbatovs [15].
