Bài báo xác định lưu lượng dòng chảy theo thời đoạn dựa vào mô hình HEC-HMS, số liệu mưa từ ảnh vệ tinh CHIRPS của NASA và Hệ thống thông tin địa lý (GIS) trong mô phỏng dòng chảy lũ tháng 12 năm 2016 tại lưu vực sông Lại Giang, lưu vực lớn thứ hai của tỉnh Bình Định (sau lưu vực sông Kôn) và có vai trò quan trọng về phát triển kinh tế-xã hội ở phía Bắc của tỉnh. Kết quả mô phỏng dòng chảy lũ rất đáng tin cậy, lưu lượng dòng chảy lũ đạt đỉnh 2542,6 m3/s tương ứng với với tần suất lũ 5%. Chỉ số kiểm định mô hình NSE với giá trị là 0,93; hệ số R2 đạt 0,78 sai số PBIAS khoảng 24% và sai số đỉnh lũ PEC = 52,01.  ABSTRACT The paper aimed to introduce the application of the HEC-HMS hydrological model combination with the CHIRPS (Climate Hazards Group Infrared Precipitation with Station) and GIS to restore flood flow data in the Lai Giang river basin in 2016. The Lai Giang river basin is the second largest basin of Binh Dinh province (after the Kon river basin), it plays an important role in socio-economic development in the North of Binh Dinh province. The simulation results of flood peaks reached 2542,6 m3.s-1 (P=5%). Model test indices such as NSE = 0.93, the correlation coefficient reached 0,78; the percentage of PBIAS error was about 24%, and peak error (PEC) was 52,01.

Цель исследования – определить особенности социально-экономического развития северо-восточной части Оренбургской губернии в первой половине XIX века. В статье рассматривается ресурсы и сдерживающие факторы развития товарно-денежных отношения населения, а также становление торговли и участники торгового процесса в Оренбургской губернии. Научная новизна исследования заключается в том, что рассматриваемая в статье проблема частично освящена в исторической среде. На основе изученных фактов автор приходит к выводу, что произошел кризис используемого способа производства, крепостническая система начала в полном объеме преобразовываться – от аграрного к капиталистическому строю, развитию товарно-денежных отношений в свою очередь способствовало становление Центрального промышленного региона, где концентрировались помыслы и промышленные точки страны.

The presented study addresses the problems of accessibility of high-quality services provided by the housing and utilities system for the population from the perspective of achieving the strategic goals of creating a comfortable and safe environment, including those formulated as national objectives by the President of the Russian Federation.Aim. The study aims to determine trends in the funding of the housing and utilities system from the consolidated budget of Russian regions in comparison with the dynamics of paid services in the field of housing and utilities, and to identify approaches to solving the problems of accessibility of highquality services and reducing regional disparities in the provision of these services.Tasks. Through the example of the North-West macro-region, the authors examine the goals, objectives, and priorities in the housing and utilities sector reflected in regional socio-economic development strategies; identify the expenditure pattern of the consolidated budget of the North-West macro-region; determine the dynamics of expenses on housing and utilities from the consolidated budget of the constituent entities of the Russian Federation located within the North-West macro-region and paid services in this field; determine the amount and dynamics of unit expenses on housing and utilities from the regional consolidated budget and compare it with household expenditure; draw a conclusion regarding the directions for improving the accessibility of high-quality services provided by the housing and utilities system for the population.Methods. Based on the statistical analysis of the 2012–2018 dynamics of the structure and absolute amount of expenditure from the consolidated budgets of the constituent entities of the Russian Federation located within the North-West macro-region and the dynamics of household expenditure on the paid services of the housing and utilities system, this study identifies the major trends and inter-regional imbalances in the funding of the housing and utilities system as a factor of realization of national priorities in ensuring a comfortable and safe environment.Results. The study shows that a number of problems persist in the regional housing and utilities systems despite the efforts made by the government, regional and municipal authorities. The constituent entities of the Russian Federation integrate guidelines for the development of this system in their socio-economic development strategies and prioritize increasing the accessibility and quality of housing and utilities services, which is reflected in regional socio-economic development strategies. One of the reasons for the persisting problems in regional housing and utilities systems and low accessibility of services for the population is the lack of a unified approach to the budgetary funding of this system. Different regions, particularly in the Russian North-West, exhibit multidirectional trends in the funding of the housing and utilities system and its support from the consolidated budget of the region. This generates and amplifies the differences between regions in the amount of budgetary funding of this system, creating unequal conditions for the population of the respective regions in terms of access to high-quality housing and utilities services. Thus, it becomes obvious that a more grounded regional budget policy is required — one that would make allowance for the existing imbalances in the funding of such services.Conclusions. To solve the identified problems, it is advisable to develop a more grounded regional budget policy that would make allowance for the existing imbalances in the funding of housing and utilities services. Mechanisms for overcoming the existing inequality of access to housing and utilities services for the population should be established not only during the development and adjustment of regional socio-economic development strategies, but also during the formation of strategy at the level of a federal district.

The article presents the results of a study on determining the relationship between the parameters of socio-economic development and changes in the labor potential of the border regions of the North Caucasus, in particular the Republic of Dagestan. The study is based on the methodology for assessing the actual state of the labor potential of the Russian regions of the southern Federal University, developed by T. Y. Kryshtaleva. A composite index was calculated for each of the components of labor potential.

The linkage between research areas and industries has brought many benefits to the socio-economic development of a country. In Vietnam, although the mechanism of autonomy in science and technology (S &T) has been established, this linkage is not strong enough. There are many objective and subjective reasons that hinder the formation and development of linkages between research areas and industries. Based on the survey of 4 universities and 4 institutes in the North of Vietnam, the article analyzes the negative factors which affect to the linkage, thus suggesting some  solutions for that. Accordingly, industries play a central role, as investors as well as consumers of S & T products; S & T activities of the universities, institutes apart from the objective of strengthening their self-capacity will mainly serve the needs of industries; The Government plays a supporting role, ensuring the linkage by legal system and also involved in the linkage through public-private partnership process.

The article suggests using the UNCTAD approach to the allocation of special economic zones, according to which SEZs can be considered as entities that meet three criteria: clearly defined boundaries of the zone territory, economic activity regime different from the national one, developed infrastructure. The article analyzes the geography of SEZs in Russia in such a broad sense. It is concluded that the Russian SEZ system and its analogues are unreasonably complex, and it is proposed to create a full-fledged state information system for territories with preferential regimes for investors, and to increase the uniformity of existing regulations. It is shown that at present preferential regimes contribute to the socio-economic development of priority geostrategic territories (with the exception of the North Caucasus), but beyond their borders they rather contribute to the growth of interregional differences in the level of socio-economic development, rather than their reduction. it is proposed not to abandon the creation of SEZs and their analogues in problem regions, but to provide investors with sufficient favorable conditions and to differentiate approach to assessing the effectiveness of SEZs and their analogues in regions with objectively different levels of investment attractiveness.
