Experimental Investigation on Partially Replacement of Cement and Fine Aggregate by Glass Powder and Vermiculite
Authors: A Dharani , P Vanmathi
Published: February 2021

Concrete is the most widely used manmade material in the construction industry. So, it is essential to utilize industrial by - products and waste products instead of concrete, which has many advantages.  Waste glass from glass manufacturing industries can be grounded and used as an alternative for cement. Glass has high silica content, thus making it potentially pozzolanic.  Finely ground glass does not contribute much to alkali - silica reaction, which can be prevented by adding mineral admixtures. Vermiculite is a low density material obtained by exfoliating rock. It can be used as replacement for fine aggregate because of it’s specific properties such as light weight, improved workability, fire resistance. This project work aims at studying the effects of replacing cement and fine aggregate by glass powder and vermiculite respectively in M35 grade concrete. Vermiculite is added in 12 %, 15 % and 18 % of fine aggregate and glass powder is added in 15 %, 18 % and 20 % of cement. The main objective is to analyse compression, splitting tensile and flexural strengths for various proportions of vermiculite and glass powder are compared with conventional specimens.

Curing plays a chief function in the improving the strength of concrete. The function of a self-curing agent is to save the water and to reduce the water evaporation from the concrete, and hence they increase the water retention capacity of concrete compared to the conventionally cured concrete. Prosopisjuliflora root powder is used as admixtures for self-curing concrete in this study. Prosopisjuliflora (SeemaiKaruvelam in Tamil) grows tremendously and spreads due to its mechanism to overcome adverse conditions of like drought and salt. With deep penetrating roots, it can draw water from deeper layers. Their root has high water holding capacity, so powder made from it can be used as admixture for self-curing concrete. This project involves the experimental investigation of self-curing of concrete by using Prosopisjuliflora root powder. Tests on fresh concrete and hardened concrete were conducted. From the results, we have concluded that adding prosopisjuliflora root powder as a self-curing agent in the concrete mix at various percentages, the addition of 0.75% of prosopisjuliflora root powder by the weight of cement attains the 28 days compressive strength of a conventional M25 grade concrete in 7 days.

Plastic is a material that is used to a great extent. Nowadays Petroleum based plastics are widely used for the commercial purpose. This kind of plastics can take more than a century to degrade. Man made plastics have Polyurethane and Polyethylene polymers. It cannot be easily degraded by micro organisms as it don’t recognize as food. When burned plastics release cancer causing carcinogenic chemicals that are harmful to people and the environment. One eco friendly alternative the current commercial plastic is “Bio plastics”. Bio plastics are biodegradable plastics that have components derived directly from renewable raw plant materials. Seven type of bioplastics were made using various combinations of renewable raw materials and plasticizers. In this project, Cassava starch is used as a main biopolymer for the production of bio degradable bags.

Water is critical for all life on the planet. Rapid industrialization and urbanization has caused India to face a water crisis since it has only 4 percent of the world’s water resources. In order to resolve the crisis, India has to look for alternative water resources which may include rainwater harvesting, grey water and sewage reuse and desalination. Grey water is defined as waste water generated from the bathroom, laundry and kitchens. Nearly 70 percent of the water used in households results in grey water which can be treated using simple technology and reused. Reuse of grey water reduces the fresh water requirements and reduces the amount of sewage sent to treatment plants. An integrated approach is needed to manage the water and waste water treatment so that water supply is kept clean and waste water is recycled for beneficial use in agriculture and industry. Water and energy are important resources in the 21st century. Water is required to supply energy, and energy is required to supply water. The reclamation of wastewater can contribute significantly to the conservation of water and energy resources. Wastewater reclamation and reuse can relieve water scarcity. Reclaimed wastewater can be substituted for natural water. Wastewater is now extensively recognized as an important source of water in water-scarce countries. In recent years not only the threats of improper greywater management have been recognized; there is an increasing international recognition that greywater reuse, if properly done, has a great potential as alternative water source for purposes such as irrigation, toilet flushing, car washing and others.

The present decade saying ban plastic is much worried about the water scarcity. It’s being revealed banning plastic bring more water scarcity as the alternative goods to plastic are more water consuming in its production. Water, air and land being the primary requirement for life should be preserved in every product invention and technological innovation. The present study proposes a suitable technology that saves all the required land resources. The so far used plastics are said to be dump threat to land resources and micro lives in it. The existence of plastic ban is a profound threat to water. Air is being polluted every day due to the exhaust of fuel and heaps of land fill. An alternative to plastics might be good invention but to recycle the already existing plastics are the real solutions to the plastics. Plastics are typically organic polymers of high molecular mass and often contain other substances. They are usually synthetic, most commonly derived from petrochemicals. However an array of variants are made from renewable materials such as polylactic acid from corn or cellulosic from cotton linters. Having a strong chemical bond that makes them degrade very slowly, which creates environmental issues and makes the soil unfit for vegetation. Conversion of plastic into alternative fuel may require high investment in terms of energy. The present project addresses the minimal energy (cost effective) to convert plastic wastes and sources to convert into crude and purified fuel resources. The results revealed that 600-800ml of crude oil can be obtained from one kilogram of one time disposable plastics through paralysis in 15 minutes. During the conversion 10% per Kg methane is also produced as by product.
O СРБИMA У ДАЛИМИЛОВОЈ ХРОНИЦИ ABOUT SERBS IN THE CHRONICLE OF DALIMIL
Authors: Гавриловић Марко
Published: February 2021

The paper examines the reasons for mentioning Serbs in two first chapters of the work called in historiography The Old Czech Chronicle of So-Called Dalimil or The Chronicle of Dalimil. Speaking about the mythic origin of the Czech people, the anonymous author mentions Serbs twice. The mentions of Serbs must be observed together with the mention of Croatia which is brought into connection with the Serbian people, and the legendary founder of the Czech state. As these data have not been separately analysed in Serbian medieval studies, the main aim of the paper is to carry out a critical analysis of the author’s construction, which is highly specific in terms of its form and content. The paper will highlight these specificities in order to arrive to at least an approximate answer as to the role of Serbs in The Chronicle of Dalimil.
МОБИЛНОСТ ЗАНАТЛИЈА НА ТЕРИТОРИЈИ СРЕДЊОВЕКОВНЕ СРБИЈE
THE MOBILITY OF CRAFTSMEN IN THE TERRITORY OF MEDIEVAL SERBIA
Authors: Фостиков Александра
Published: February 2021

Током периода средњег века, који припада дугом аграрном добу, занатство се развијало и гранало у складу са сопственим чиниоцима развоја, што је утицало и на диференцијацију и на стратификацију самих занатлија. Како би мобилност ових произвођача на територији средњовековне Србије била детаљније истражена, на податке из изворног материјала примењена је постојећа подела типова покретљивости, усклађена са датим временом. Тако је и поред скромног процента поименично познатих занатлија било могуће установити да су оне биле мобилне, као и указати на поједине типове покретљивости, било из угла друштвене географије, друштвено социјалне стратификације или померања унутар породице.

During the Middle Ages, which belong to the long agrarian age, crafts developed and branched in line with own factors of development, influencing both the differentiation and stratification of craftsmen. To examine in more detail the mobility of these producers in the territory of medieval Serbia, the existing division of mobility types, harmonised with the given time, was applied to the data from source material. Thus, despite the modest percentage of craftsmen known by name, it was possible to establish that they were mobile and highlight individual types of mobility, either from the aspect of social geography, social stratification or shifts within families.
МИТРОПОЛИЈСКА ЦРКВА БЛАГОВЕШТЕЊА У СМЕДЕРЕВУ METROPOLITANATE CHURCH OF THE ANNUNCIATION IN SMEDEREVO
Authors: Катић Срђан
Published: February 2021

Рад се бави црквом Благовештења при Смедеревској митрополији, коју је изградио деспот Ђурађ Бранковић. У тој велелепној цркви, грађеној по угледу на Манасију, 1453. године похрањене су мошти светог апостола јеванђелисте Луке, а 1456. и 1458. вероватно су сахрањени и деспот Ђурађ и његов син и наследник Лазар. У раном периоду османске власти, после другог освајања Смедерева 1459. године, тај важан сакрални објекат је порушен под неразјашње­ним околностима, а место на којем се налазио ни до данас није пронађено. Циљ рада је да на основу османских извора утврди какав је био верски статус те цркве након освајања, који су разлози довели до њеног рушења, као и да се установи када се то догодило. Намера је и да се укаже на утицај који је разградња и уклањање централног сакралног објекта у Смедереву имало на урбану структуру града. Посебна пажња посвећена је лоцирању цркве Благовештења, при чему су коришћена нова сазнања о распореду верских, војних, привредних и стамбених објеката у смедеревској тврђави у првим деценијама османске власти. The paper deals with the church of the Annunciation in the Smederevo Metropolitanate, built by despot Đurađ Branković. In 1453, the relics of the Holy Apostle and Evangelist Luke were placed in this sumptuous church, modelled upon Manasija, and in 1456 and 1458, despot Đurađ and his son and successor Lazar were probably buried there. In the early period of the Ottoman rule, after the second conquest of Smederevo in 1459, this important sacral building was demolished under unexplained circumstances, and its place has still not been found. The aim of the paper is to determine, based on Ottoman sources, the religious status of this church after the conquest and the reasons for and time of its destruction. A focus is also placed on the impact of the demolition and removal of this central sacral building in Smederevo on the urban structure of the town. A particular emphasis is placed on locating the church of the Annunciation, by relying on new knowledge about the distribution of religious, military, economic and residential buildings in the Smederevo fortress in the first decades of the Ottoman rule.

Objetivou-se avaliar o perfil dos consumidores de ovos do município de Aquidauana-MS. A pesquisa foi realizada por meio de entrevistas com consumidores diretamente nos postos de venda, localizados em diferentes pontos da cidade mediante a aplicação de um questionário previamente definido. Verificou-se que a grande maioria dos entrevistados era do sexo feminino (72,5%), com idade entre 21 a 40 anos (47,5%), com grau de instrução referente ao ensino superior completo (28%) e renda familiar próxima a três salários mínimos (50,5 %). A maioria dos entrevistados consome ovos três vezes por semana, preferencialmente fritos (44%) e avaliam a validade do produto na hora da compra (66,8%). A maior parte da população entrevistada preferem ovos de casca vermelha (66,5%), embora não achem que a cor da casca afete no seu valor nutricional (58,9%). Ainda que 58% dos consumidores entrevistados tenham afirmado que a cor da gema influencia o valor nutricional do ovo, 59,3% não tem preferência por essa característica. Observou-se percentual significativo (71%) de consumidores que não possuem conhecimento do valor nutricional, mas que afirmam que o consumo de ovos não faz mal à saúde (67%). Conclui-se que na cidade de Aquidauana-MS há um satisfatório consumo de ovos, no entanto, detectou-se que há algumas informações básicas que os entrevistados demonstraram não possuir conhecimento, deste modo, torna-se necessário a divulgação e esclarecimento dessas por meio dos rótulos das embalagens dos ovos, Marketing criativos nos estabelecimentos de venda, exposição de banners, elaboração de folders e panfletos, e criação de páginas virtuais, possibilitando uma maior expansão informativa a respeito do ovo para a população Aquidauanense.
The eternal spirit of Thalassa: The transmission of classical maritime symbolism into byzantine cultural identity
Authors: Wade Janet
Published: February 2021

In antiquity, the sea held an important place in the hearts and minds of those living in the Mediterranean region, and maritime motifs were popular across a range of literary and artistic genres. Classical maritime imagery was transmitted almost seamlessly into early medieval and Byzantine cultural identity, despite its overt polytheistic connotations. Mosaics depicting maritime deities and mythological seafaring scenes were installed in private residences and Christian churches. Poets wrote of Fortune steering the ship of life and orators spoke of leaders at the helm of their state. Didactic and ecclesiastical texts taught of the corrupting nature of merchants and the sea, and compared the trials and tribulations of everyday life and faith with storms and squalls. The Christian church also became viewed as a ship or safe harbour. Seafaring imagery was regularly imbued with both traditional and contemporary religious, political, and cultural relevance. This paper argues that the ongoing popularity of maritime symbolism was not only a throwback to classical times or because seafaring themes had a greater relevance to Christians than non-Christians. Thalassa (the Sea) had always been important in Greek and Roman thought, and she acquired a more tangible and pervasive presence in the lives of those in the late antique Roman East. Unlike Rome, the eastern capital at Constantinople was itself a great maritime entrepot. The maritime cultural milieu that dominated coastal Mediterranean regions played an influential role in the city and its far-reaching empire. Constantinople sat at the centre of a vast network of seaports and was a major hub of Roman culture and communication. With the city's foundation, classical maritime imagery acquired a contemporary cultural and political relevance; even as the Graeco-Roman world slowly evolved into a Christian one.

ABSTRACT

 

The incidence of type 2 diabetes mellitus (T2DM) increase significantly. Lifestyle changes, including patterns and types of food, have an effect on the occurrence of T2DM. Changes in the composition and type of gut microbiota have a significant impact on the incidence of metabolic diseases, including T2DM. Ketogenic diet, which consist of high fat, moderate protein, and very low carbohydrates, is currently a common diet for weight-loose program in obese people, where obesity is a risk factor for T2DM. However, the use of this diet as management in T2DM subject is still a controversy. It is proven that ketogenic diet can alter the composition of Bacteriodetes to Firmicutes in T2DM subject and may improve the metabolic profile of this subject. The ketogenic diet can be recommended as a diet for T2DM subject with attention to the special conditions of the subject.

Validation of WINROP algorithm as a screening tool for retinopathy of prematurity in a northern Spanish cohort
Authors: Fernández-Ramón Raúl
Published: February 2021

Introduction: WINROP (Weight, Insulin-like growth factor 1, Neonatal Retinopathy of Prematurity) is a computer-based ROP risk which correlate postnatal weight gain with the developed of treatment-requiring ROP. The purpose of this study was to evaluate the ability of the WINROP algorithm to detect severe (Type 1 or Type 2) ROP in a Spanish cohort of infants.

Methods: Birth weight, gestational age, and weekly weight measurements of preterm infants (>23 and <32 weeks gestation) born between 2015 and 2017 were retrospectively collected and entered in WINROP algorithm. Infants were classified according alarm activation and compared with ROP screening outcomes. Sensitivity, specificity, and predictive values were calculated.

Results: A total of 109 infants were included. The mean gestational age was 29.37 ± 2.26 weeks and mean birth weight was 1178 ± 320 g. Alarm occurred in 47.7 % (52/109) of neonates, with a mean time from birth to alarm of 1.9 ± 1.4 weeks. WINROP had a sensitivity of 100% (CI 95%, 59-100), a specificity of 55.9% (CI 95%, 45.7-65.7), a positive predictive value of 13.5% (CI 95%, 11.1-16.2) and a negative predictive value of 100% (CI 95%, 93.7-100) for predicting severe ROP.

Conclusion: The WINROP algorithm has proven to be a useful tool in the detection of severe ROP in our cohort. Nevertheless, in extremely preterm infants (GA <28 weeks) the results should be taken with caution and an optimization of WINROP can be necessary to improve its utility in other populations.
DEVELOPMENT OF A METHODOLOGY FOR CONSTRUCTING TAXATION SYSTEMS IN DEVELOPED COUNTRIES (USING THE EXAMPLE OF WESTERN EUROPE AND THE USA)
Authors:   All-Russian Public Organization of Small and Medium-sized Businesses “Support of Russia”, Fedosimov B.A.
Published: February 2021

The article presents a theoretical study on the methodology evolution in constructing tax systems in Western Europe and the United States. Also, in a number of cases, the methodology and experience of other European countries (Eastern Europe) and Asian states is examined in the framework of a comparative analysis. Basing on the results of the study and analysis of the methodology genesis of constructing tax systems in Western countries, it is stated: 1) at the moment, in most developed countries, direct taxes dominate in the methodology for constructing the taxation system (more than 100 types of taxes and fees are distinguished); 2) if developing countries at the stage of economic recovery, the key task is to increase the degree of tax collection in order to ensure the completeness of financing public spending, then for developed countries the main task is to curb the excessive growth of the public sector of the economy in conditions when the economy is already approaching such a threshold beyond which it is unreasonable to increase the level of the fiscal burden. However, as the practice of recent years shows, it is extremely difficult to achieve this result. Due to the fact that the methodology for constructing the tax system in the Soviet period was subjected to radical destruction, and the level of tax collection is more than 2 times lower than the average European indicators, not even reaching the optimal level (60%), the results of a study on the use of methodological tools by Western countries to solve these problems are acquiring practical significance and special interest for Russia.

Published: February 2021

The authors of the work investigate one of the key areas of the Russian economy - the oil industry. It is hydrocarbons that account, on average, up to 40% of the Russian budget revenues. Oil revenues provide macroeconomic stability of the state, employment of the population in the oil and gas sector and related industries, as well as the stability of the ruble currency in the international market and prices for most types of products in the domestic market. The aim of the work is to study the possibilities of improving the current mechanisms for controlling price formation for key brands of hydrocarbons in order to increase the economic and energy security of the Russian Federation. The scientific study also analyzes the impact of the prices for Urals and Brent crude oil on the Russian ruble quotes against the US dollar and other world currencies. The correlation between the increasing of main oil brands value on the hydrocarbon market and strengthening of the Russian currency, as well as the filling the Reserve and other national funds, as one of the factors in the development of the Russian economy, is studied. The scientific basis of the research was Russian and foreign publications, state statistical materials, opinions and assessments of experts in the field, as well as the authors’ own developments. While studying the materials, the authors considered such indicators as: prices for “Brent”and “Urals” oil, their relationship and the reasons for the fall in prices for gasoline and hydrocarbon-derived materials, as well as the impact on the prices of goods in other economic sectors. The paper studies and selects the most effective responses to changes in the market environment in the context of nonstationary fuel prices.

Published: February 2021

The purpose of this article is to study the question, to which extent the tasks of transition to sustainable urbanization through high-quality infrastructure investments are taken into account in the framework of concession agreements implemented in Russia. Analysis of the tender documentation for 70 announced tenders for concluding concession agreements showed that the criteria for competitive selection are, as a rule, economic indicators related to the volume of investments, financial obligations of the grantor and the time frame for the creation or reconstruction of the concession object. Environmental and social criteria when concluding concessions are used as long-term regulation parameters and target values for the performance indicators of the concessionaire, mainly in the utilities sector. The article substantiates the need for a transition to a sustainable-oriented approach to the implementation of concession agreements. The principle of project sustainability means that the project uses green technologies (use of energy obtained from renewable sources, environmentally friendly materials, innovative solutions to reduce carbon dioxide emissions, waste, rational use of resources, etc.) and sustainable institutions (rules, contributing to the achievement of social and environmental sustainability). The role of the state in enhancing the environmental sustainability of concession agreements should be to build a system of incentives that will primarily contribute to the initiation of a green multiplier and a more complete provision of environmental and social risks of the project implementation at all stages of its life cycle. This will be facilitated by the inclusion of sustainability criteria in the tender documentation and the assessment of projects at the pre-project stage using the total cost of ownership (TCO) methodology, which takes into account the costs, including for the elimination of negative environmental and social consequences of the concession project implementation. The inclusion of criteria to ensure that environmental requirements are met throughout the supply chain throughout the life of a project will provide multiplier environmental benefits. This will require additional costs on the part of the grantor, but it will create market incentives for environmental innovation and attract additional private investment in quality infrastructure.

The article provides a retrospective analysis of the development of entrepreneurship in Russia from the 9th century to 2020. 4 periods in the development of small and medium-sized businesses in Russia are highlighted and the characteristics of each of the periods are given. At the first stage, the development of entrepreneurship was facilitated by the formation of cities, which became a trade center. In the 9th century, the trade route "from the Varangians to the Greeks" was actively used. The study showed that the state has always had a strong influence on the development of entrepreneurship. The most difficult in the development of Russian entrepreneurship is the Soviet period, after which the revival of small and medium-sized enterprises began with the support of the state. Attention is paid to modern legislation governing the financial and economic activities of SMEs. A retrospective analysis of government programs to support SMEs from 1994 to 2020 was carried out. The program of state support, which has been in effect since 2016, "Strategy for the development of small and medium-sized businesses in the Russian Federation for the period up to 2030" is considered in more detail. In Russia, 95% of private enterprises are microbusiness. The SME Strategy 2030 proposes a classification of SMEs into 2 groups: mass SMEs and hightech ones. Attention is paid to target indicators of SME development for each of the groups until 2030. By 2030, the turnover of SMEs should increase by 240% compared to 2014, the share of SME exports in the total volume of Russian exports should increase to 12%, the number of high-performance jobs in small and mediumsized businesses should increase, etc.
Humanidades ambientales y ambientes humanizados

En el contexto de políticas neoliberales en que está sumergida Sudamérica, parece ser importante el “para qué servimos”. La utilidad parece ser una moneda corriente en estos tiempos, los ataques a la comunidad científica, que sufren particularmente las ciencias sociales al momento de los recortes presupuestarios, se vinculan justamente a la aparente inutilidad en momentos de crisis de las Ciencias Sociales. Una paradoja, por cierto, en caso de urgencias parece que las ciencias que se ocupan de las cosas útiles a los humanos cobran mayor relevancia que aquellas que se ocupan de los humanos en sí. A pesar de esto, la escisión entre las llamadas ciencias naturales y ciencias humanas está quedando cada vez más obsoleta, y en este sentido hay algunas sendas interesantes que han comenzado a explorarse.

I start by displaying a detail from a painting by Veronese, an Italian Renaissance painter. This painting has different titles if you look for it on the internet, but one of  the titles is The Dialectic, and the detail that you see here represents one way of trying to depict the human understanding of the network of meaning within which we all live, and the way that as scientists and scholars we reflect upon language and meaning as a kind of web, which binds us together with each other, with other human beings, and a web which we can examine in order to foster our own cognitive creativity.
Amazonía

Published: February 2021

El tema que vamos a desarrollar en esta exposición forma parte de una publicación que está saliendo en estos días en Chile y cuyo título es Amazonía: el río tiene voces. Imaginario y modernización. La investigación que dio lugar a ella está relacionada a varias motivaciones. La primera, y más importante de todas, es la certeza de la necesidad de llamar la atención sobre un área geográfica-cultural que es escasamente conocida en los estudios de la cultura del continente y que, en el campo de las humanidades y las ciencias sociales, lo es sobre todo desde la mirada antropológica. Su desconocimiento disciplinario en el latinoamericanismo, por una parte, así como la importancia central que desempeña en el contexto de la crisis medioambiental que vivimos, por otra parte, hacen que su estudio y difusión tengan una importancia fundamental.

The number of vehicles in Indonesia has increased each year, both two-wheeled and four-wheeled vehicles; this is inversely proportional to the development of road infrastructure in Indonesia, which has not experienced much change or improvement. Supposedly, with the increase in the number of vehicles, road infrastructure must also keep pace so that things such as the accumulation of cars on the road do not occur, traffic accidents and congestion become obstacles to carrying out activities. Therefore, it is necessary to make a system to detect and classify vehicles' types in this study using two types of vehicles, namely cars and motorbikes. According to the Indonesian Central Statistics Agency (BPS), it is the highest number. The classification system uses digital image processing techniques, a science to study how an image is formed, processed, and analyzed by a computer to produce information that humans can understand. The method used in this research is the Extreme Learning Machine (ELM), a part of artificial intelligence in feedforward neural networks, where this method can solve regression and classification problems. The data used in this study are 25 images of cars and motorbikes as training data and 15 photos of cars and motorbikes as test data, respectively. The results obtained from this study are a system for classifying two types of vehicles, namely cars and motorbikes, with an accuracy rate of 86.6%.

В данной статье рассматривается советское образование в 1920-1960-х гг. Большая часть населения СССР была неграмотна, поэтому основная цель работников народного образования данного периода заключалась в усилении борьбы за повышение успеваемости и дисциплину учащихся. Добиться, чтобы каждый выпускник советской школы отличался высокой идейностью, культурой, инициативностью и настойчивостью в борьбе за новое и передовое. В рассматриваемый период, школа стала не только местом получения образования и грамотности, но и повсеместно, особенно на сельской территории, центром воспитания молодежи от 7 до 17 лет. Кроме того, на вечерней смене учебы занимались молодежь от 18 и выше. Поэтому коммунистическая партия и правительство СССР придавало особое значение вопросам реализации реформирования народного образования. Поэтому, представляется актуальным изучение советского опыта функционирования системы образования представляется важным. Авторы на основе анализа архивных источников Государственного архива Новейшей истории Ульяновской области (фонд 8 – Отдел народного образования), а также материалах историографического анализа таких авторов, как Забалухина Н.В., Пашкин А.Г., Мухамедов Р.А. и др. которые рассматривали основные направления работы партийно-государственных органов Ульяновской области по модернизации образовательной системы и динамику количества учебных учреждений и обучающихся. В заключении, сделан вывод о том, что партийные органы власти в Ульяновской области и педагогический коллектив Областного Отдела народного образования, Районного Отдела народного образования и школ смогли заложить крепкий фундамент для дальнейшего развития системы образования.
