THE road to better child health has been discussed in relation to the doctor and his training, health services and their distribution. We have dealt with the unavoidable question of costs. Particular attention has been given to some of the advantages and dangers of decentralization of pediatric education and services. Each of the various subjects has been discussed from the point of view of its bearing on the ultimate objective of better health for all children and the steps necessary to attain this goal. Now, we may stand back from the many details of the picture, view the whole objectively and note its most outstanding features. First is the fact that the improvement of child health depends primarily upon better training for all doctors who provide child care, general practitioners as well as specialists. This is the foundation without which the rest of the structure cannot stand. The second dominant fact is the need for extending to outlying and isolated areas the high quality medical care of the medical centers, without at the same time diluting the service or training at the center. The road to better medical care, therefore, begins at the medical center and extends outward through a network of integrated community hospitals and health centers, finally reaching the remote and heretofore isolated areas. Inherent in all medical schools is a unique potential for rendering medical services as well as actually training physicians. The very nature of medical education—whereby doctors in training work under the tutelage of able specialists in the clinic, hospital ward, and out-patient department—provides medical services of high quality to people in the neighboring communities.

The discrepancy between the pace of economic growth rates, needs of enterprises and population for transportation, quality of the road network is a significant infrastructural limitation for growth. The paper is devoted to the analysis of large scale investment projects aimed at the removal of infrastructural restrictions, i.e. the national project “Secure and High-Quality Roads” and “Comprehensive Plan for the Modernization and Expansion of Main Infrastructure”. It is noted that the project “Secure and High-Quality Roads” for Krasnodar Krai will become a prerequisite for the effectiveness of transport infrastructure. “Comprehensive Plan for the Modernization and Expansion of the Main Infrastructure” including such federal projects as “Europe – Western China”, “Sea Ports of Russia”, “Northern Sea Route”, “Railway Transport and Transit”, “Transport and Logistics Centers”, “Communications Between the Centers of Economic Growth”, “Development of Regional Airports and Routes”, “High-Speed Rail Links”, “Inland Waterways” will increase the investment activity in the transport sector of the region. The paper presents the results of statistical analysis aimed at the identification of significant economic effect from capital investments in the road infrastructure of Krasnodar Krai. It is revealed that investments into transport and communications stimulate the economic growth and also reduce the accident rate on highways in the long run. In addition, the increase in the density of paved public roads stimulates the passenger turnover in the short run and is also a significant factor in the reduction of the accident rate. The downward trend of paved roads in the total length of roads indicates the necessity to invest in the improvement of the quality of existing roads. The author emphasizes that in order to achieve the goals mentioned in the infrastructural projects under analysis, it is necessary to improve the monitoring system of content and development of the infrastructural frame of the territory, evaluate the effectiveness of administrative decisions for the accomplishment of the goals indicated in the infrastructural projects under analysis.

The national project “Safe and high-quality roads” is aimed at the development, creation and effective use of intelligent transport systems. Today, there are many technical solutions to improve road safety, as well as optimize the process of organizing traffic. Often, these solutions lie not only in the plane of design, in the use of technical means for organizing traffic, in reconstruction of the existing street-road network, but also in the use of intelligent transport systems. The article has developed a concept for the development of a road-road network in Khabarovsk, in connection with the adoption by the Government of the Khabarovsk Territory of a decision on the construction of a transport interchange at the intersection of Voronezh-Bolshaya Streets in Khabarovsk, as part of the national project “Safe and High-Quality Roads” in the Khabarovsk Territory. The collection and analysis of statistical data, over a five-year period, on the types of frequency of occurrence of reported road traffic accidents. Visual and grapho-analytical methods identified the focus of the concentration of traffic accidents at the considered site of the road network of the city of Khabarovsk. Based on the method of conflict points, factors that influence the accident rate of an existing section of the road are studied. Several options for improving the quality and safety of traffic are considered: changing the number of lanes, regulating the traffic light, building a multi-level traffic intersection. Using modern software systems, based on methods of mathematical modeling, for several options developed models of traffic flows, identified the maximum possible comfortable and safe traffic conditions. Substantiated recommendations are given for improving the quality and safety of road traffic by improving the existing road situation.

Graph partitioning has many applications. We consider the acceleration of shortest path queries in road networks using Customizable Contraction Hierarchies (CCH). It is based on computing a nested dissection order by recursively dividing the road network into parts. Recently, with FlowCutter and Inertial Flow, two flow-based graph bipartitioning algorithms have been proposed for road networks. While FlowCutter achieves high-quality results and thus fast query times, it is rather slow. Inertial Flow is particularly fast due to the use of geographical information while still achieving decent query times. We combine the techniques of both algorithms to achieve more than six times faster preprocessing times than FlowCutter and even faster queries on the Europe road network. We show that, using 16 cores of a shared-memory machine, this preprocessing needs four minutes.

Постановка задачи. Необходимо рассмотреть технологию ремонта дорожных покрытий нежесткого типа с применением холодных асфальтобетонных смесей на битумах марок БНД, СГ и МГ. Требуется разработать математическую модель конструкции автомобильной дороги, позволяющую демонстрировать распределение температуры по толщине слоя покрытия в зависимости от конструктивных параметров дороги с учетом теплофизических свойств материалов и температурных условий её эксплуатации. Также надлежит уточнить влияние температуры смеси на предел прочности холодной смеси заводского производства. Следует провести ремонт выбоин покрытия в производственных условиях при пониженных температурах воздуха. Результаты. По результатам моделирования распределения температуры в слое покрытия доказано, что применение холодных асфальтобетонных смесей обеспечивает высокое качество ремонтных работ при температуре воздуха выше 30 °С. Получены данные о зависимости температуры нагрева основания от температуры воздуха и толщины слоя, которая обеспечивает температурные режимы холодной смеси при её уплотнении. Установлено, что предел прочности покрытия зависит от температуры. Максимальная величина предела прочности холодного асфальтобетона заводского производства обеспечивается при температуре уплотнения смеси 50-55 °С. Проведенный ремонт выбоин дорожного покрытия при пониженных температурах воздуха доказал возможность выполнения ремонтных работ с высоким качеством в данных производственных условиях. Выводы. Доказана эффективность нагрева основания выбоины перед укладкой холодной асфальтобетонной смеси при ремонте дорожных покрытий нежесткого типа со снижением температуры воздуха ниже 5 °С. Установлено влияние температуры основания покрытия на ее равномерное распределение в зависимости от температуры воздуха и толщины слоя покрытия при выполнении ремонтных работ. Полученные данные о зависимости предела прочности холодного асфальтобетона заводского производства от температуры воздуха позволяет определять параметры уплотняющих машин, обеспечивающих высокое качество ремонтных работ. Statement of the problem. It is essential to consider the technology of repair of road surfaces of non-rigid type using cold asphalt-concrete mixtures on bitumen grades BND, SG and MG. It is important to develop a mathematical model of the road structure that enables modeling the temperature distribution over the layer thickness, depending on the design parameters of the road considering the thermal and physical properties of materials and the temperature conditions of the road operation. It is also necessary to specify the effect of the mixture temperature on the tensile strength of the cold mixture of factory production. Potholes of the coating must be repaired at low air temperatures of different repair technologies in production conditions. Results. Based on the results of modeling the temperature distribution in the coating layer, it is proven that the use of cold asphalt-concrete mixtures ensures high quality of repair work at air temperatures above +30 ° C. The dependence of the heating temperature of the base on the air temperature and the layer thickness is obtained, which provides the temperature conditions of the cold mixture during compaction. It is established that the ultimate strength depends on temperature. The maximum value of the strength limit of cold asphalt concrete of factory production is provided at the compaction temperature of the mixture at +50-55⁰C. The repair of potholes of the road surface carried out in production conditions at low air temperatures proved the ability to perform repair work with high quality of work. Conclusions. It is proven that it is effective to heat the base of the pothole during repair on non-rigid road surfaces at low air temperatures before laying a cold asphalt-concrete mixture. The influence of the base temperature on its distribution over the layer thickness depending on the air temperature and the layer thickness during repair work is established. The obtained dependence of the strength limit of cold asphalt concrete of factory production on temperature allows us to determine the parameters of compacting machines that ensure high quality of repair work.

The Russian road system is an important part of the transport structure. High wear, difficulty in driving, and a decrease in road safety lead to a decrease in the number of transportation in the country. In addition, imperfect road geometry does not allow increasing the speed mode on the highway. This article presents the features of the route simulation, taking into account the above disadvantages. The geometric aspects of the design of the road route in the plan are considered. Disadvantages and limitations of existing tracing methods are shown. The task is to select and adapt a geometric modeling program to solve the problems of high-quality road tracing in the plan. The «FairCurveModeler» program is proposed for geometric modelling of high quality curves according to smoothness criteria. A comparative testing of the methods of the «FairCurveModele»r program with the methods of the top CAD system «NX12» is carried out. The results obtained allow for a smoother construction of curves in the design of automobile and other routes.

Іntroduction. The article notes the relevance of defining the role of doctrine in the development of the law, given the rapid legislative races on the road to European integration. It is emphasized that the legal doctrines of different States may differ in the strength of their national characteristics, certain objective factors – historical, political, economic, cultural, religious and the like. As an example, it is possible to call existing since ancient times, doctrines of natural rights, popular sovereignty, social contract, the theological doctrine of state and law, rule of law and the like. Тhe aim of the article. Given the above, the aim of the article is the study of the legal doctrine as a kind of matrix quality law and the definition of its influence on legislative activities. One of the definitions of the term «matrix» is understanding it as a General framework, models, diagrams, anything. Results. Scientists, analyzing the legal doctrine distinguish two main functions: on the one hand it is the theoretical basis for the legislative process, and on the other source of law, and, accordingly, is implemented in the enforceability of the process. Based on the reviewed definitions of legal doctrine and its role in law-making activities, its influence on the formation of high-quality law, as the conclusion should focus on the following features that characterize its matrix, to create high-quality law. Сonclusion. As a conclusion it is noted that the capacity of legal doctrine to serve as a matrix in the legislative and realtime processes due to its functional and content side: on the one hand, it is a waste years of theoretical (conceptual) framework for law-making; second, it objectifies the results of scientific research in the form of fundamental legal ideas and concepts (ideals, values, principles, norms); thirdly, the doctrinal knowledge transforms in legislation, filling it with quality content. Consequently, the legal doctrine as a body of basic scientific ideas is intended to be a repository of fundamental principles and values formed in the process of development of society, perceived them, and which should be to find objective expression in national law.

In this editorial, we leverage the metaphor of the road trip to help those authors submitting to the Journal of Service Research and other publications craft high-quality qualitative research (HQQR). We outline three criteria as hallmarks of HQQR: relevant research addresses important problems or gaps, rigorous research makes data collection and analysis transparent, and responsive research reflects the ability to adapt to concerns and critiques as the project unfolds. We unpack four essentials of the road trip that enable authors to deliver on the above criteria: vehicle (theory), route (research design), traveling companions (coauthors, participants), and safety kit (planning, tools). We explain how choices made by researchers not only can foster HQQR but can also fuel the journey to publication. Our “Road Trip Checklist” provides a quick reference to specific questions researchers should ask to address each essential element and offers article exemplars that masterfully respond to these questions. We hope this editorial encourages researchers to draw on qualitative techniques to explore service-related topics that would benefit from immersive fieldwork and that it inspires the necessary guidance and confidence to get on the road.

The text concerns an analysis of theses and justification for the judgment of Province Administrative Court in Gdańsk dated 18 September 2018 (case no. II SA/Gd 328/18). Although the judgment is based on particular factual state of affairs, its conclusions seem to be connected with common problems in the area of so-called ‘landscape acts’ adopted at the municipal level. Firstly, the judgment states that landscape acts may refer to campaign materials presented in connection with elections or referendum. In the commentary, this approach is approved, although the reasoning is developed via a detailed interpretationof the spatial management and planning act and electoral code. Later in the judgment it is claimed that landscape acts may cover rules of locating advertisements nearby elements of the road infrastructure. Moreover, this standpoint is shared in the gloss, detailed relations between landscape act and act on public roads as well as judgments in similar cases have been additionally presented. The last issue raised in the judgment was the problem of the legal grounds of imposing an obligation to maintain small architecture objects, advertisement boards /units and fences in the proper condition. As the court claimed, this is possible, because maintenance of the object is the element of its location, and this is also connected with the obligation to use high-quality materials. Moreover, it is stated that the problem of maintaining these objects has not been fully regulated in building law. This approach is accepted in the gloss, although attention is drawn to some inconsistencies in the justification, as well as to the possibility of raising other, moreaccurate arguments by the court.
