This study aimed to assess dietary habits among medical science students in Duhok city. Methods: A descriptive cross-sectional study was conducted from 20th January 2019 to 28th April 2019. The cluster sampling procedure enrolled 359 medical science students aged 18-26 years from five medical science colleges in Duhok city. Dietary habits were obtained by direct interview. The questionnaire consists of three parts: socio-demographic characteristics, questions regarding main meals, and measuring dietary habits using a Likert scale. Data were analyzed using SPSS version 23. Results: Most of the study participants were males 56.8% with a mean age was 21 years. Slightly more than half of the students 52% claimed they ate three main meals every day and about 11% skipped it. About 45% of the participants ate breakfast every day. The most frequently eaten meals and beverages among students were soft drinks 80%, rice 80%, snacks 72%, and sweats/chocolate 70%. Decreased intake of fruits 60%, vegetables 50%, and dairy products 38% were observed. There were significant differences among males and females in food consumption and beverages namely, sports drinks, eggs, cheese, red meat, chips, and sweets/chocolate. Conclusion: The current study indicated that skipping meals was typical among students. Most students had unhealthy food habits and behaviors according to the standard recommendations for eating and drinking daily. The assessment of dietary habits as a part of the health component can serve as a screening tool to identify adult students to improve their well-being and dietary habits.

Published: March 2022

The article is devoted to comprehending such important categories for modern pedagogy as freedom in the space of upbringing, the formation of a free personality from the standpoint of a humanistic approach to the personality of a pupil. The main attention is paid to the pedagogical heritage of O. S. Gazman, his pedagogical ideas and scientific and theoretical generalizations. The pedagogical legacy of O. S. Gazman is perceived today not only in the context of the pedagogically important judgments he proposes, methodological generalizations expressed in the era of perestroika. From the standpoint of pedagogy of the XXI century, the organization of modern Russian education, the ideas expressed by O. S. Gazman appear as an innovative philosophical and pedagogical concept, in which the main concepts are freedom, self-education of the individual, and pedagogical support. At the same time, in our opinion, work on the most important ideas of O. S. Gazman today in domestic pedagogy is insufficient. To a greater extent, perhaps, his idea of pedagogical support is being comprehended and used, which today has acquired some methodological features and is being implemented in many educational institutions, primarily thanks to his students and followers, N. N. Mikhailova and S. M. Yusfin. O. S. Gazman’s judgments regarding freedom as the core of the formation of a modern personality, capable of making his own choice, realizing his various life strategies and scenarios, correlating with his moral attitudes and ready to fully bear responsibility for this choice – of course, are insufficiently commented and far from are fully included in the theory and practice of modern pedagogy. However, there is no doubt that such innovative ideas rightfully puts O. S. Gazman on a par with outstanding domestic thinkers, such as, for example, S. I. Gessen practice. The purpose of the article is to analyze the most significant scientific provisions stated by O. S. Gazman and concerning the essence of freedom and the resources of its formation among pupils. Basic research methods: analysis of scientific and methodological literature, comparative analysis of theoretical and pedagogical concepts; theoretical generalizations. Research results: it was concluded that, firstly, O. S. Gazman firmly established freedom as an integral category, new for its time, understood as the integrity of the personality core of a developing person; secondly, the ideas of O. S. Gazman and his assumptions regarding the implementation of the principle of free-spirited upbringing, which he managed to implement in his pedagogical activity, today finally acquire the features of practical comprehension and application.

The problem and the goal. The problem of organizing independent work of students has now become even greater due to distance learning, since now it is necessary to revise and modernize the organization of the educational process. The purpose of the article analyze the opinions of various authors on the role of independent work in the learning process, compare their approaches. Methodology. The study was conducted on the basis of studying the modern educational environment. It is not easy to teach a student to study independently. To organize a full-fledged independent work, it is necessary: – Create favorable conditions for the organization of work. – Teach to set specific goals. The student knows what he should get from a large amount of information, what to pay attention to. – Teach you how to plan your work. If you do not follow a certain plan, you can spend a lot of time, but you will not achieve results. – Teach to choose the means of learning. The student should know what will help him better in acquiring knowledge on a specific topic. He doesn’t just have to review articles, videos, textbooks, you need to teach him to find meaningful information from certain sources. Analyzing the psychological and pedagogical literature, we understand that the concept of “Independent work” is revealed from different sides. The main thing for the teacher is to analyze all sides, choose the most optimal ones for himself, which are suitable for both the student and the teacher, which will be applied only in the interests of the student.

Cultural Diplomacy of Kosovo after the Declaration of Independence
Authors: Saliu Hasan , Llunji Venera
Published: March 2022

The article analyzes a segment of the cultural diplomacy of non-state actors of Kosovo who have communicated with foreign audiences through the international media in the period after the country’s declaration of independence in 2008. Analyzing the content of media coverage for non-state actors, the article examines the given messages of these actors in some powerful international media, which relate to the possibility of increasing the international image of the new country. The article finds that Kosovar non-state actors have continuously communicated with the global and regional public because it has been impossible for state actors to convey any positive message to the latter. The article, moreover, shows that Kosovar famous athletes and artists or world champions represent the soft power of Kosovo, because they have found enough space to be exposed in the international media. A significant feature of cultural diplomacy in the case of Kosovo is that the presence of hundreds and thousands of foreign peacekeepers in a country with as much security as other Balkan countries is also seen as an opportunity to influence the country’s international image.
V. F. ODOEVSKY’S “RUSSIAN NIGHTS”: TWO NOVELS?
Authors: Sytina Yuliya
Published: March 2022

The article raises the question of two editions of V. F. Odoevsky’s novel “Russian Nights”. In the 1860s, the writer wanted to republish it and made a number of amendments and additions to the novel. Odoevsky did not complete this work, and for the first time after the 1844 edition “Russian Nights” were published only in 1913. The publisher S. A. Tsvetkov was guided by the principle of following the “last will of the author” and included Odoevsky’s later changes in the text of the novel. This principle has become defining for the publishers of “Russian Nights” in the Literary Monuments series. This version of the novel is still being republished. At one time P. N. Sakulin sharply criticized this approach and pointed out the differences between Odoevsky worldview in the 1830s and 1860s. This difference is clearly reflected in the amendments proposed by the author. This article supplements and expands the argument of the researcher. The 1844 Preface to the Works and the draft of the Preface from the 1860s are compared, and later notes and insertions are analyzed in the context of the novel. The study shows that in the later years of his life Odoevsky departs from his earlier mysticism and romantic style. Later changes give “Russian Nights” a tendentiousness, destroy the unity of the author’s position. They should not be included in the main text of the novel. The standardization of the author’s spelling and punctuation, which is characteristic of Soviet re-editions of the classics, also violates the poetic space of the novel. It is important to note that the writer created the novel precisely as an aesthetic creation, and the slightest nuances of the author's score are vital to it. When republishing “Russian Nights”, it is advisable to be guided by the “historical principle” (“editio princeps”).

Padang is one of the cities in Indonesia with a majority of the Moslem population. It is a crucial thing to be considered by Moslems. This study aims to determine the critical point of halal food found at restaurants in the city of Padang as the novelty of this study. In this study, qualitative methods are used with a population of all restaurants in the city of Padang. The research sources data were informants or restaurant managers by using purposive sampling techniques. The data research was observations and interviews with informants and documentation. Data processing in this study used NVivo 11 software and it is descriptively equipped with data reduction, data presentation, and conclusion making. The result of this research show there are two dominant cooking techniques used in food processing; 65 dishes for frying and 37 dishes for boiling with coconut milk. The food processing using the burned technique, boiled with water, and sautéed are little. There are three types of beverages served; mineral water, sachet drinks (tea, coffee, cappuccino), and fruit processed (fruit juices) as the beverages menu. Identification results show the critical point of halal food in restaurants are divided into four; 1) high water content (beef, chicken, offal, Tempe, and tofu), 2) low water content (salt, sugar, flavoring, sachets, flour, rice flour, paneer flour, and crackers), 3) liquid raw materials (mineral water, cooking oil, soy sauce, and vinegar), and 4) processing equipment (brush polish). Food ingredients and processing equipment that have a critical halal point are meat, crackers, bulk oil, mineral water, and brushes. While other Food Materials, unique packaged ones, already have a halal label on the packaging. This research can contribute in providing information to Moslems about the importance of halal food from all aspects as good as facilitate the restaurant to get halal certification.

The purpose of this study is to describe: (1) Haley’s model of human perceptual space category used to create the metaphorical expression of craving in the Tanha Vagga verse of the Dhammapada scripture, (2) the distribution of Haley's category of human perceptual space that is most prominently used to create the metaphorical expression of craving in the Tanha Vagga verse of the Dhammapada scripture, (3) the state of the ecological system as seen in the metaphor of craving in the Tanha Vagga verse of the Dhammapada scripture based on the distribution of the use of the Haley’s category of the human perceptual space. This research is a descriptive-qualitative research, with Content Analysis technique. The data source is the Tanha Vagga Dhammapada Scripture. The results showed: (1) in the Tanha Vagga scripture Dhammapada there are 31 metaphors of craving that can be categorized into the five spaces of human perception according to Haley's model, including the categories of being, energy, terrestrial, object and living. (2) Based on the results of the distribution of the use of the Haley’s model of human perceptual space, it was found that the living category was the most prominent type of craving metaphor category with a percentage of 35.4%, (3) the percentage distribution results reflected the unbalanced state of the ecological system in the Tanha Vagga verses of Dhammapada. The metaphorical expression of craving in the Tanha Vagga of the Dhamapada scriptures is packaged in a metaphorical form which means controlling lust (taṇhā = Pali) which causes dukkha (suffering) and the cycle of rebirth (saṃsāra). Buddhism seeks to eliminate taṇhā to eliminate dukkha.

Authors: Rohmatulloh Dawam Multazamy , Marwantika Asna Istya
Published: March 2022

As one of the demanding discourses of Indonesian Islam, Islam Nusantara has made a further round of Indonesian Muslim polarisation among the proponents on the one side and the opponents on another, let alone in the digital era nowadays. For the Muslim communities, new media are not only used for communication activities but also to assist the da'wa (proselytisation) and its contestation. This paper, thus, aims to portray activities of social media users, particularly Instagram, using the #IslamNusantara hashtag to convey their ideas. This paper seeks to explore the motives of how the Instagram users do involve in the contestation of #IslamNusantara and to what extent they publish their argument to support, criticise, or even refuse the concept of Islam Nusantara. The method used in this article is netnography, analysing a total of 344,000 hashtags #IslamNusantara on Instagram. Finally, this paper anticipates a yet-to-end online contestation among the Muslim communities within a new interest pool: #IslamNusantara.
Partner in Jihad: Marriage, Women and Deradicalised Terrorists in Indonesia
Authors: Toyibah Dzuriyatun
Published: March 2022

The involvement of women in jihad has increased significantly in many countries including Indonesia. This changes the image that women are underrepresented in relation to acts of jihad and terrorism. Drawing from in depth-interviews with six wives of disengaged terrorists in 2016, the current article aims to explain their marriage and support in jihad.  Applying religious radicalisation frameworks ranging from pre-radicalisation to jihadisation, the participants have not achieved the final step. They mostly believe in allowing jihad in conflict-ridden countries, but not in Indonesia. Marriage and family are very important to introduce the ideology of allowing violence in conflict-ridden areas. Their husband’s affiliation to a radical group has the potential to support the wives to strengthen their network within the terrorist circle.  However, in general, the participants were not intensively engaging in religious studies (pengajian), were limited from connecting with their past friends after their husbands were sentenced. They disagreed with their husband’s dream and actions. Therefore, the potential network for continuing radicalisation will not develop very significantly.

This paper reports the improved load-bearing structure of a hopper car for transporting pellets and hot sinter. In order to increase the strength of the load-bearing structure of a hopper car under the influence of high temperatures from the transported cargo, the use of cladding made of composite material has been proposed. This solution also contributes to a 5 % reduction in the wagon's tare compared to the prototype car.
The dynamic load on the load-bearing structure of a hopper car was determined. This study was carried out for the case where an empty wagon was moving over an irregularity between the rail joints. The calculations showed that the studied dynamics indicators did not exceed the permissible values. At the same time, the ride of a hopper car is rated as "excellent".
The main indicators of the strength of the carrying structure of a hopper car were determined taking into consideration the proposed improvement. That took into account the temperature effect exerted on the load-bearing structure of a hopper car by hot sinter. It was established that the maximum equivalent stresses occur in the zone of interaction of the girder beam with the pivot beam and are about 290 MPa. At the same time, stresses in the cladding of a hopper car are about 200 MPa, which is 12 % lower than those in a regular structure.
Modal analysis was carried out to determine the frequencies and shapes of the natural oscillations of the bearing structure of a hopper car with a composite cladding. The calculation results demonstrated that the first natural frequency exceeds 8 Hz. Therefore, the safety of the wagon is provided.
The coefficient of fatigue resistance of the load-bearing structure of a hopper car was calculated. It was established that its value is almost twice as high as the permissible one. That is, the resistance to fatigue of the supporting structure is provided.
The research reported here could contribute to ensuring the strength of the load-bearing structures of hopper cars, reducing the cost of maintenance, and increasing the efficiency of their operation.

Published: March 2022

Reuse of wastewater has been widespread in this era to support the water sustainability process. Therefore, treated wastewater should be conveyed to suitable places and adopted for different uses. This study presents an empirical relationship between the Darcy-Weisbach and Hazen-Williams equations for four types of pipe material (ductile iron, GRP, concrete, and plastic) by using WaterCAD Version 8i. Two hydraulic models were developed to estimate the head loss in pipes by using different diameters: first, using pipe diameters from 800 mm to 1,200 mm for a flow rate of 1.16 m3/s, second, adopting pipe diameter from 1,600 mm to 2,000 mm for a flow rate of 4.63 m3/s. The study results are the head loss values obtained from the Darcy-Weisbach and Hazen-Williams equations, which were used to correlate them using IBM SPSS Statistics. The correlation coefficient between both equations turned out to be 0.991, 0.990, 0.990, and 0.990 for ductile iron, GRP, concrete, and plastic pipe materials. Additionally, the relationship between head loss and pipe diameter is negatively proportioned for both equations. Also, both head loss equation results are the same. The head loss values in the Darcy’s equation were higher for ductile iron and GRP materials, while being lower for concrete and plastic materials for both models. Selecting concrete or plastic pipes to convey treated wastewater is better than other pipe materials. Another conclusion is that the pipe diameter affects the head loss magnitude irrespective of the kind of equation whether Darcy-Weisbach or Hazen-William equation. Finally, this relationship is very useful for designers in converting the head loss values obtained using these equations.

This paper reports a procedure devised to forecast the level of chemical pollution of the atmosphere, which includes a mathematical model for the distribution of the concentration of dangerous gas in the atmosphere at its active deposition by dispersed jets of liquid, as well as a technique for its implementation. Based on the differential equations of gas distribution in space, a phased model of the propagation of a cloud of a dangerous chemical substance was built. The model describes stages in the discharge of a dangerous gaseous substance from emergency technological equipment, the deposition of dangerous gas by a finely-dispersed flow, and free propagation of the cloud in the air. The reported mathematical model makes it possible to calculate the size of pollution zones while determining the boundary safety conditions. When forecasting, the main meteorological parameters, the width of the deposition zone, and the chemical properties of both the gas and liquid are taken into consideration. The comparative analysis of the results of forecasting a conditional zone of chemical damage with the free propagation of the cloud, and at the active deposition by precipitation or technical devices, was carried out. The simulation results revealed that with an increase in the wind speed from 1 m/s to 5 m/s, the size of the affected area increases by 2.7 times, while the concentration of dangerous gas in the cloud falls by 2.5‒3 times. An algorithm has been proposed for integrating the devised methodology of forecasting the level of chemical pollution of the atmosphere into a general cycle of emergency management. It should be especially noted that the devised procedure contains the entire range of components that are necessary for its practical application. It includes a description of the procedure and practical recommendations for the use of the proposed technique in the elimination of emergencies, as well as a list of probable events when the use of the developed procedure would be most effective.

Published: March 2022

With the daily increase in document flow, as well as the transition to paperless document management around the world, the demand for electronic document management systems is increasing. This significantly requires optimization of these systems in terms of quality document information retrieval and document management. However, research based on statistical methods cannot effectively handle large amounts of data extracted from electronic documents. In this regard, machine learning methods can effectively solve this problem. This paper presents an approach to building a model of an intelligent document management system using machine learning techniques to ensure efficient employee performance in organizations. The authors have solved a number of problems to optimize each of the document management subsystems, resulting in the development of an intelligent document management system model, which can be effectively applied to enterprises, government and corporate institutions. The feasibility and effectiveness of the proposed model of intelligent document management system based on machine learning and multi-agent modeling of information retrieval processes provides maximum reliability and reduced time of work on documents. The obtained results show that with the help of the presented model it is possible to further develop an intelligent document management system that will allow an electronic document to qualitatively go through the whole life cycle of a document, starting from the moment of document registration and finishing with its closing, i.e. execution, which will greatly facilitate the daily work of users with large volumes of documents. At the same time, the paper considers the application of topic modeling methods and algorithms of text analysis based on a multi-agent approach, which can be used to build an intelligent document management system.

This paper has substantiated a modified method that, within the framework of the adaptive zero-order Brown’s model, provides for increased accuracy in predicting processes with unknown dynamics masked by the noise of various levels. The forecasting method modification essentially involves an adaptive technique for determining the weight of the correction of the previous forecast, taking into consideration the recurrent state of the predicted process in time. To investigate the accuracy of the forecasting method, a test model of the process dynamics was determined in the form of a rectangular pulse with unit amplitude. In addition, a model of additive masking noise was defined in the form of a discrete Gaussian process with a zero mean and a variable value of the mean square deviation. Based on determining the exponentially smoothed values of current absolute forecasting errors, the dynamics of forecast accuracy were examined for the modified and self-adjusting methods. It was found that for the mean quadratic deviation of the masking noise equal to 0.9, the smoothed absolute prediction error for the modified method does not exceed 23 %; for the self-adjusting method – 42 %. This means that the prediction accuracy for the modified method is about twice as high. In the case of an average square deviation of masking noise of 0.1, the smoothed absolute prediction error for the modified and self-adjusting methods is approximately the same and does not exceed 10 %. That means that at a low level of masking noise, both prediction methods provide approximately the same accuracy. However, with an increase in the level of masking noise, the self-adjusting method significantly loses the accuracy of the forecast to the proposed modified method.

This paper has analyzed protective materials for timber building structures and established the need to devise reliable methods for studying the process of water absorption by the surface of the construction structure necessary for designing new types of fire-retardant materials. Therefore, it becomes necessary to determine the conditions for the formation of a barrier for water absorption and to elucidate a mechanism for inhibiting the transfer of moisture to the material. In this regard, a mathematical model of the intensity of water mass transfer when using a polymer shell made of organic material as a coating has been built, which makes it possible to assess the effectiveness of the polymer shell by the amount of water absorbed. Based on the experimental data and theoretical dependences, the intensity of absorption of water by wood was calculated; and it has been established that the protective coating reduces the amount of water absorbed by more than 20 times. The results of determining the weight gain by a sample during water exposure indicate an ambiguous impact of the nature of protection on water absorption. In particular, this implies the presence of data sufficient for the qualitative process of inhibition of moisture diffusion; and detecting, on its basis, the point in time when the drop in the coating's efficiency begins. Analysis of the results of experiments reveals that the maximum increase in mass in the case of water absorption by a non-treated sample of wood was 40 % while the increase in the mass of wood samples treated with mixtures of oil and paraffin was less than 28 %. At the same time, the best protection is shown by a mixture of oil with paraffin within 90÷95 %. Thus, there are grounds to assert the possibility of directed regulation of wood protection processes through the use of polymer coatings that can form a protective layer on the surface of the material, which inhibits the rate of absorption of water.

This paper reports an improved method for processing the image of a vehicle's license plate when shooting with a smartphone camera. The method for processing the image of a vehicle's license plate includes the following stages:
– enter the source data; 
– split the video streaming into frames; 
– preliminary process the image of a vehicle's license plate;
– find the area of a vehicle's license plate;
– refine character recognition using the signature of a vehicle's license plate; 
– refine character recognition using the combined results from frames in the streaming video; 
– obtain the result of processing.
Experimental studies were conducted on the processing of images of a vehicle's license plate. During the experimental studies, the license plate of a military vehicle (Ukraine) was considered. The original image was the color image of a vehicle. The results of experimental studies are given. A comparison of the quality of character recognition in a license plate has been carried out. It was established that the improved method that uses the combined results from streaming video frames works out efficiently at the end of the sequence. The improved method that employs the combined results from streaming video frames operates with numerical probability vectors.
The assessment of errors of the first and second kind in processing the image of a license plate was carried out. The total accuracy of finding the area of a license plate by known method is 61 % while the improved method's result is 76 %. It has been established that the minimization of errors of the first kind is more important than reducing errors of the second kind. If a license plate is incorrectly identified, these results would certainly be discarded at the character recognition stage.

The drying of crushed plant-derived materials, in particular crushed cotton stems, is a complex heat-exchange and technological task. Resolving this task successfully ultimately determines the specific energy costs of the drying process and the quality of the resulting products. The rational drying regime of crushed cotton stems should ensure the minimum possible process duration, energy costs, and provide the necessary quality characteristics of the dried material. To address this issue, it is necessary to investigate the influence of technological parameters of the process (the temperature and filtration rate of the heat agent), as well as the thickness of the stationary layer of crushed cotton stems, on drying kinetics.
This paper has generalized experimental studies into the kinetics of filtration drying of crushed cotton stems during the period of complete saturation of the thermal agent with moisture.
The influence of the temperature of the drying agent, the speed of its filtering through a stationary layer of different heights of wet crushed cotton stems, on the kinetics of filtration drying has been shown. The study's results demonstrate the dynamics of moisture removal at different parameters of the heat agent and the heights of the stationary layer of crushed cotton stems.
The resulting dependence  has been established, which is used to determine the value of the kinetic coefficient η for crushed cotton stems; the value of the kinetic coefficient has been calculated, a=20.74 1⁄m. The dependence  has been derived, using which makes it possible to generalize the kinetics of filtration drying of crushed cotton stems during the period of complete saturation of the heat agent with moisture within the limits of changing the moisture content of the veneer
The comparison of the experimental data with those obtained theoretically has shown that the maximum absolute value of relative error does not exceed 15.2 %.

In order to prevent oxidative damage, an experiment was conducted to determine the effectiveness of berries extracts (Aronia melanocarpa Elliot and Ribes nigrum L.) in the production of half-smoked sausages. The recipe of half-smoked sausages with a polycomponent composition of raw materials includes semi-fat pork with muscle tissue, tendon-free lean pork, tendon-free Muscovy duck meat, side pork, hydrated bamboo fiber.
Berry extracts (Aronia melanocarpa Elliot and Ribes nigrum L.) at concentrations of 0.2–0.5 % to the weight of crude minced meat were added to the examined samples of minced meat. Sample No. 1 was a control, that is, made without the addition of extracts of berries.
During the storage of products with extracts, an acidic number, a peroxide number, a thiobarbituric number, and the predefined indicators of microbiological safety were determined.
The addition of chokeberry extract in the amount of 0.2–0.5 % to the minced meat weight significantly slows down the hydrolytic oxidation of lipids in finished products, effectively inhibits the peroxide oxidation of fat. The use of blackcurrant extract also has an antioxidant effect but is weaker. Stabilizing the peroxide oxidation of lipids in half-smoked sausages has the effect of inhibiting the formation of secondary oxidation products, which is confirmed by the results reported here. The amount of secondary oxidation products was the smallest at the end of the shelf life of the product with a concentration of chokeberry extract of 0.5 % and was 0.197±0.001 mg MA/kg, which is 3.74 times lower than that in the control.
The addition of extracts of chokeberry and black currant reduces microbiological contamination and has a bacteriostatic effect. The most effective is the introduction of chokeberry extract in the amount of 0.05 %, which reduces the oxidative damage to fat by more than three times.
