In an iPWR (integral pressurized water reactor), the pressurizer is located at the top of the reactor vessel; this configuration requires the investigation of the mechanisms adopted for the homogenization of boron. In previous work, three representative experiments were conducted in an experimental installation made of stainless steel with a volumetric scale equal to 1:200, representing one-fourth of the pressurizer of an iPWR. The test facility layout was mounted so that the test section was fed with water or saline solutions with different concentrations, representing scenarios of boration or deboration. To determine the concentration at the inlet and outlet of the test section, samples have been collected every 10 min during the experiments representing some scenarios. The main goal in this work was to investigate how well mixing during boron dilution transients in the pressurizer of a small modular reactor can be modelled accurately by CFD (Computational Fluid Dynamics) codes. Two CFD codes were used, the commercial ANSYS CFX and the open source CFD code OpenFOAM. The use of open source software such as OpenFOAM offers a way to CFD gain acceptance in the licensing. The results of the comparison of simulations with an experiment at the test section were presented and showed a very good agreement. It was verified that deviations are less than 4%, both codes can be used to accurately represent this phenomenon. In order to improve future experiments, the dispersion of the solution inside the test section is studied with the aim to propose positions for sensors. A first simple configuration is proposed, but some further simulations will be done to find an optimum configuration.

Published: January 2021

It is well-known that melliferous bees are the most sensitive indicators of ecologic conditions of natural environment. Researches in recent years show that bees and bee products can accumulate selectively some heavy metals, radioactive substances, pesticides and other polluters. Scales of heavy metals accumulation on the territory of Ukraine, as toxins of technologic origin unfortunately increase. Environmental pollution by heavy metals leads to their accumulation in plant and animal raw materials and production, consequently their quality decreases. It was proved that apiary accommodation in heavy metal polluted territories leads to their accumulation in pollen, honey bee-comb and wax. But the questions concerning study of peculiarities of sources, ways of pollution and heavy metals content in bee products are not enough lightened, and that was the purpose of our work. Generalized we present in literature information and results of our researches about the use of bees and bee products in quality of bioindicator contamination of environment by heavy metals. Dependence of content of heavy metals is set in the organism of bees in relation intensity of greening to contamination of environment. It is marked on the necessity of lead through of systems research in relation to determination of content of heavy metals in fabrics of bees and bee products with the purpose of search of new methodological approaches for authentication these toxicant of objective environment of contamination and him apimonitoring. Methodological elements of the researches of regularities of heavy metals and lipids content in the tissues of different anatomic sections of the organism and bee products were elaborated.
Impacto de las aflatoxinas B1/M1 sobre el bienestar de las vacas lecheras y su presencia en productos lácteos
Authors: Pichardo-Matamoros Derling José , Elizondo-Salazar Jorge Alberto
Published: January 2021

La aflatoxina B1 (AFB1) es la aflatoxina más tóxica y prevalente a nivel mundial, causa aflatoxicosis aguda, tiene efecto carcinogénico y citotóxico en animales y humanos. La AFB1 es un metabolito secundario producido por especies de Aspergillus, particularmente, en regiones tropicales y subtropicales. Por lo general, los cereales son los alimentos que representan el riesgomás significativo de exposición para los animales y son los más utilizados en la formulación de alimentos balanceados para las explotaciones lecheras. Las vacas que ingieren alimentos contaminados con AFB1 excretan aflatoxina M1 (AFM1)a través de la leche, a una tasa de transferencia que va desde0,30 a 7,26%.La AFM1 tiene efecto carcinogénico, pero menos potente que el de la AFB1. La AFM1 es estable a los procesos de pasteurización de la leche empleados en la industria láctea. El consumo de productos lácteos contaminados con AFM1 aumentael riesgo para padecer cáncer en humanos, lo que la convierte en uno de los problemas más importantes de inocuidad alimentaria. Considerando el impacto en seguridad alimentaria de las AFB1/AFM1 para los animales y el hombre, en este trabajo se proporciona una perspectiva sobre la relación entre AFB1 y los alimentospara las vacas lecheras, la transferencia de AFB1 a AFM1 en la leche y derivados lácteos, efectos sobre los rendimientos productivos y reproductivos en el animal, importancia en la salud pública, así como, las estrategias más convenientes para controlar los niveles de AFB1 y AFM1 en la cadena de producción de la industria láctea.El control del impacto de las AFB1/AFM1 en las lecherías debería incluir un plan de vigilancia y monitoreo en la finca empleando técnicas analíticas confiables sobre muestras de leche provenientes del tanquein situque ayuden a fortalecer las medidas de control sobre los alimentos para garantizar el bienestar de las vacas y la inocuidad alimentaria.
Tensiones constitutivas entre el diseño y la implementación del currículo en la enseñanza de las Ciencias Naturales en el contexto escolar colombiano
Authors: Villanueva Meneses Rodolfo , González Melo Hamlet Santiago
Published: January 2021

La transición entre las políticas educativas y su aplicación real en las aulas constituye un tema que promueve diferentes e interesantes reflexiones en el campo de la enseñanza de las Ciencias Naturales en Colombia. La discusión sobre los niveles de concreción curricular debe ir más allá de la mera crítica, para convertirse en un factor de reflexión el cual sitúe a la persona educadora en el campo de la producción académica a través del análisis de la teoría y de la reflexión de su práctica pedagógica. En ese marco, el presente artículo pretende escudriñar a nivel teórico algunas concepciones del currículo de Ciencias, su articulación con las políticas nacionales y, problemáticas derivadas de su puesta en funcionamiento. Es así como al inicio se expone una breve reseña histórica del currículo de Ciencias en Colombia, para luego dar lugar a los lineamientos curriculares que operan en la actualidad y desarrollar algunas reflexiones en torno a las implicaciones de estos tránsitos y las tensiones con su puesta en marcha por parte del cuerpo docente. Para finalizar, se analizan algunas situaciones específicas en donde las tensiones entre lo planeado y ejecutado dan pie al planteamiento de una reflexión propositiva en términos de la resolución de las dificultades en la cotidianidad del profesorado.
Ver para saber: los cortometrajes en la didáctica conversacional del español LE/L2
Authors: Domènech Conxita
Published: January 2021

Este ensayo presenta la enseñanza del español como lengua extranjera o segunda lengua (LE/L2) y de nivel intermedio o avanzado a partir de cortometrajes, género desestimado tanto en el ámbito fílmico como en el académico. Asimismo, propone que los cortos dejen de ser una pequeña herramienta que se muestra un par de veces al semestre para divertir a los/las estudiantes y que, por el contrario, se conviertan en los protagonistas del aula de español LE/L2. Aunque se podría considerar una propuesta de cine o de cultura, me decanto por el campo de la didáctica de la conversación. Al igual que los cortometrajes, la competencia comunicativa, la interacción o la competencia conversacional suelen desatenderse. Por eso, este ensayo examina los cortometrajes y la conversación en la enseñanza del español LE/L2 y, sobre todo, ofrece una propuesta didáctica a partir de los cortometrajes. Antes de pasar a la propuesta, explicaré brevemente las características intrínsecas, la historia reciente y las ventajas pedagógicas de los cortos. Continuaré con la presentación de los cortometrajes escogidos y, también, proporcionaré los datos básicos sobre cada uno de ellos. Terminaré tomando uno de los cortos y diseñando una unidad pedagógica en torno a él, que servirá de modelo para los otros cortometrajes.
Ocio en un país imaginario. Identidad, alteridad y cuestiones genéricas en Idle Days in Patagonia (1893) de W. H. Hudson
Authors: Lencina Eva
Published: January 2021

Este artículo caracteriza algunos de los aspectos centrales de Idle Days in Patagonia (1893), del naturalista y escritor anglo-argentino William Henry Hudson. En esta obra, el autor rememora su estadía en el territorio patagónico entre 1870 y 1871. Se busca examinar la obra desde la perspectiva imagológica y caracterizar la relación del sujeto con la imagen de sí y de los otros que se construye en el texto. Importa también la relación con el espacio, gracias a la cual se concibe el ocio como actividad intelectual productiva, que configura una representación del vínculo semimístico con la naturaleza. El núcleo de nuestro interés está puesto en la convergencia entre identidad y alteridad en el medio rural argentino decimonónico: el desarrollo de las estrategias hudsonianas de escamoteo de la identidad argentina en un texto escrito para Inglaterra, a la par de una búsqueda de empatía con la alteridad indígena in absentia. Se busca también discutir el estatuto genérico de un texto tan ambiguo como lo es Idle Days in Patagonia, que, como su autor, escapa a las clasificaciones. Finalmente, se compara brevemente esta obra de Hudson con una obra trunca de Eduardo Holmberg, debido a cómo el posicionamiento de cada autor en sus respectivos campos literarios echa luz sobre los modos de representación imaginaria del espacio patagónico.

Optimizing the quarantine cost for suppression of the COVID-19 epidemic in Mexico
Authors: Choque Rivero Abdon E. , Khailov Evgenii N. , Grigorieva Ellina V.
Published: January 2021

This paper is one of the few attempts to use the optimal control theory to find optimal quarantine strategies for eradication of the spread of the COVID-19 infection in the Mexican human population. This is achieved by introducing into the SEIR model a bounded control function of time that reflects these quarantine measures. The objective function to be minimized is the weighted sum of the total infection level in the population and the total cost of the quarantine. An optimal control problem reflecting the search for an effective quarantine strategy is stated and solved analytically and numerically. The properties of the corresponding optimal control are established analytically by applying the Pontryagin maximum principle. The optimal solution is obtained numerically by solving the two-point boundary value problem for the maximum principle using MATLAB software. A detailed discussion of the results and the corresponding practical conclusions are presented.

Economic results in the breeding of goats under intensive and extensive systems
Authors: Stankov K.
Published: January 2021

The goal of the present study is to establish the economic results from the application of intensive, semi-intensive and extensive systems of breeding. The study included two Bulgarian goat breeds: Bulgarian Dairy White (BDW), with different levels of selection and raised under two different systems, barn and pasture-barn-based, as well as Local Longhair breed goats raised under a pasture-barn system.
The data on the productivity, income and expenses were obtained from the financial statements of the farms, and calculated per individual doe.
The highest natural, economic and cost-efficiency results were exhibited by the does of the BDW breed, which is bred in a barn all year long. The herd is under strict selection control, with an average dairy capacity of 820 l per doe and fertility of 1.8 goatlings. These goats brought income in the amount of BGN 702.50 per doe, while the expenses were BGN 537.70. Profit with subsidy was reported as BGN 165.85, and without subsidy – BGN 85.85. They achieved cost-efficiency of the income with subsidy amounting to +23.57, and + 13.77 without subsidy, while the expenses were, respectively, +30.84 and + 15.97.
Significantly lower values of natural and economic parameters were exhibited by the does of the BDW breed, which were under a pasture-barn system and without selection control. Even though they were lower, profits and cost-efficiency were still positive. Expectedly, the lowest natural and economic parameters were observed in the does of the Bulgarian Local Longhair breed. They registered a loss of BGN 21.39 without subsidy and a profit of BGN 18.61 with a subsidy for animals under selection control. The cost-efficiency of income and expenses without subsidies was negative, whereas with subsidies it was positive, albeit at minimum values.

Authors: Paleva-Kadiyska Bl.
Published: January 2021

Introduction: Sewing machines a set of mechanisms that work together, of which the most dynamic mechanism is the one that drives the needle. Stitch quality, the stitch strength and the productivity of the sewing machine largely depend on the work of the needle bar mechanism. The main task during the study dynamics of the sewing machine mechanisms is to determine the energy balance. Purpose: The aim is to determine the total energy consumed by the mechanisms per one full rotation of the main shaft of each machine; the share of energy consumed by each unit of the needle bar mechanism for one turnover; the ratio of the energy of each of the links of the mechanism both during the working motion and during the free motion of the needle. Materials and Methods: The object of the study is the energies of the needle bar mechanisms of the sewing machines Juki DDL5550 and Textima 8332. An energy distribution analysis was performed during the working process and the free stroke of the sewing needle. The energies of the mechanisms of the two sewing machines were compared. Results: Were calculated maximum energy values are as follows: of the rocker: for Juki DDL5530 Ek = 2,8051 kg.m2/s2 and for Textima 8332 Ek = 1,3864 kg.m2/s2; of the executive links - the needle bars: for Juki DDL5530 Ek = 5,9507 kg.m2/s2 and for Textima 8332 Ek = 4,3696 kg.m2/s2; general energy of needle bar mechanism: for Juki DDL5530 Ek = 8,7487 kg.m2/s2 and for Textima 8332 Ek = 5,7416 kg.m2/s2. Conclusion: The comparative analysis reveals that the energy consumption of the needle bar mechanism of Juki DDL5530 is significantly higher. Consequently, the energy consumption indicator of the Textima 8332, which is directly driven without a clamp, is more efficient.
Alcorexia - psychosocial determinants of the eating disorder
Authors: Hoffmann B.
Published: January 2021

Although alcorexia has not yet been formally classified as a disease entity, it is a serious, complex health problem. Alcorexia belongs to behavioral eating disorders and consists in restricting the amount of food intake in order to increase the ability of drinking alcohol without fear of gaining weight. As far as so called traditional eating disorders are usually motivated by a latent desire to be lean and control your body, alcorexia appears to be motivated by the desire to drink large amounts of alcohol along with the desire to be slim.
As the disorder is progressing, the situation may change, both in the direction of anorexia as well as addiction to alcohol. For the purposes of this article, I use the term "alcorexia," but it should be added that the term is used interchangeably with such terms as drunkorexia, alcoholic anorexia, or alcoholic bulimia.

Authors: Nugraha Reza Sukma , Arummi Afnan , Hidayati Tri Yanti Nurul
Published: January 2021

Sebagai bacaan anak, novel grafis Salma Ta’rifu Huquuqahaa (STH) karangan Fathimah al-Ma’dul menunjukkan karakteristik yang relevan dengan sastra anak. Selain ditampilkan dengan ilustrasi yang dapat menarik perhatian pembaca anak, narasinya pun menunjukkan unsur didaktik yang jelas, yaitu kesadaran akan hak-hak anak dan kepedulian terhadap lingkungan sosial. Moral tersebut ditampilkan melalui karakter anak bernama Salma. Akan tetapi, permasalahan muncul dalam karakterisasi Salma yang menjadi tokoh utama sekaligus penyampai moral. Selain itu, representasi moral di dalamnya perlu dibaca secara kritis agar maknanya dapat ditangkap oleh pembaca, baik pembaca anak-anak maupun pembaca umum. Oleh karena itu, dilakukan penelitian kualitatif dengan menggunakan teori Semiotika Roland Barthes sebagai pendekatan. Dengan melakukan pembacaan bertahap (signifikansi) terhadap tanda-tanda yang ada di dalam teks, diperoleh hasil bahwa teks STH menampilkan moral terkait kesadaran akan hak-hak anak dalam rangka melakukan sosialisasi Konvensi Hak-hak Anak PBB sebagai pedoman hak-hak anak secara global. Selain itu, mitos yang diungkapkan melalui sosialisasi itu adalah kampanye terhadap hak-hak anak di Mesir yang digagas oleh Suzanne Mubarak pada saat teks diterbitkan (2016).

Authors: Martinelli Paolo , Colombo Matteo , de la Fuente Albert , Cavalaro Sergio , Pujadas Pablo , di Prisco Marco
Published: January 2021

The paper presents an experimental program carried out to check the load bearing capacity of a steel fibre reinforced concrete (SFRC) floor in northern Italy. The extensive mechanical characterization focused on the suitability of 3 non-standardized test methods for quality control and tensile constitutive curve assessment was performed, this consisting of: uniaxial tensile test (UTT), double edge wedge splitting test (DEWST) and double punching test (DPT) to characterize the post-cracking mechanical properties of the material. The joint experimental programme, carried out at the Politecnico di Milano and at the Universitat Politècnica de Catalunya, included the flexural characterization of four shallow beams (1.5 × 0.5 × 0.25 m3) and six standard notched beams (0.55 × 0.15 × 0.15 m3). All the samples were produced from the same batch and with the same SFRC mix which was applied for the floor. After that, 192 cores were drilled from the shallow beams and subjected to either UTTs, DEWSTs or DPTs. The stress level, the scatter and the constitutive curves derived from the non-standardized tests were identified and analysed. The calculated constitutive curves were used to predict the behaviour of the shallow beams.

A numerical study on the effect of vent/wall area ratio on Trombe wall thermal performance
Authors: Kaya Ercan Serif , Aksel Murat , Yigit Sadik , Acikara Turgut
Published: January 2021

Trombe walls are the most widely applied passive systems that utilise solar energy for heating massive walls. Although studies have been undertaken in the fields of Trombe wall application and design, the research on the effect of the vent area and the number of vents on the performance of a Trombe wall remains limited. In this context, a parametric study investigating the effect of the vent-to-wall-area ratio on Trombe wall performance was conducted. A computational fluid dynamics model was employed for validation analysis. The results were verified by experimental measurements of temperature. At each step of the parametric study, the vent-to-wall-area ratio in the Trombe wall model was increased by 2% starting from the unvented case, and the results were simulated per ratio. In this study, temperature measurements of the glazing, thermal wall and space were employed as the evaluation criteria. The results of the parametric runs showed that a Trombe wall with eight separate air vents and an 8% vent-to-wall-area ratio provides the maximum heating performance. Furthermore, a monolithic vent configuration with an 18% vent-to-wall-area ratio performed slightly better compared with other configurations of monolithic air vents.
A basis for developing sustainable earthquake-resisting structures
Authors: Grigorian Mark , Kamizi Mozhgan , Sedighi Siavash
Published: January 2021

Sustainable seismic design (SSD) is a relatively new field of study that promises improved human welfare and innovative developments in structural engineering worldwide. In the present context, SSD refers to structural operability with a view to post-earthquake realignment and repair (PERR). The difference between conventional seismic design and SSD is the expected behaviour during and after earthquakes. In conventional earthquake-resistant systems, attention is focused on the response of the structure to code-level seismic demand whereas, in SSD, the post-earthquake attributes of the system are as important as those during the event. SSD is neither part of contemporary curricula nor codes of practice. This article promotes the notion that a structure can be seismically sustainable if it is able to prevent actual collapse, overcome residual effects and lend itself well to PERR. In order to gain insight into the inner workings of SSD, resort has been made to adaptive design, bioinspiration and the study of structural differences between conventional and seismically sustainable structures. It is shown that conventional seismic design can be upgraded to SSD without resorting to untenable costs and technologies.

Katılımcıların %6.7’si ülkemizde hangi kanser türlerinin tarama programı olduğunu bilmediğini belirtirken, %92’si meme kanserine yönelik tarama programı olduğunu bilmiştir. Katılımcıların sadece %16.5’i daha önce gaitada gizli kan testi yaptırdığını belirtmiştir. Katılımcıların medeni durumu, çalışma durumu, sigara kullanımı ve daha önce kanser tanısı alma durumlarına göre, kanser taraması yaptırma arasında anlamlı bir farklılık olduğu tespit edilmiştir (p < 0.05).

Sonuç: Bu çalışma sonucunda, erkeklerin kanser risk faktörlerine ve belirtilerine ilişkin bilgi eksikliklerinin olduğu ve tarama programına yeterince katılmadığı ortaya çıkmıştır. Bu sonuçlar doğrultusunda erkeklerin kansere ilişkin bilgi düzeyini artırmaya yönelik toplum temelli çalışmaların yararlı olacağı düşünülmektedir.
On the Issue of Administrative Liability for Split Purchases
Authors: Voroshilov Victor , Tishchenko Vyacheslav
Published: January 2021

The authors of the article investigate the law enforcement practice of instituting administrative action against public officials who act as purchasers for splitting in federal and municipal government procurement. The legal framework that regulates relations, concerning the choice of procurement modalities, is analyzed. Different points of view on the notion and features of artificial splitting in procurement, formulated in scientific literature, are presented. On the basis of their analysis and taking into account the judicial and administrative practice that is being formed, the features are proposed that are the most representative of the essence of artificial splitting in procurement. According to the results of their research, the authors come to the conclusion about legitimacy of artificial splitting in procurement and illegality of instituting administrative action against purchasers from the perspective of the regulatory framework in place, and also about the necessity of changing both regulatory and protective provisions of legislation in order to exclude artificial splitting from the procurement practice of purchasers.

The main issue currently being addressed by the assortment policy is determining the set of product groups that will be the most preferable for the successful oper-ation of a retail enterprise. The most important direction of the assortment policy is to retain regular customers and attract the interest of new ones. Assortment management is of particular importance in the food market. A significant role in providing the population with food is played by regional distribution networks, which form the demand for products through competent assortment manage-ment. The article discusses ways to improve the assortment policy of regional re-tailers that are engaged in the food market. A general description of the function-ing of regional retail chains is illustrated by the example of «Slata» group of companies in order to optimize the process of managing the assortment of food products.
Peculiar Internality in Family Relations of Ischaemic Heart Disease Patients
Authors: Orlova Maria
Published: January 2021

The study shows the importance of economic deprivation in a situation of severe somatic disease using ischemic heart disease patients as an example. This factor affects the subjective control in significant social relationships including family relationships. The purpose of this study is to analyze the impact of the disease situation and economic deprivation on presence of internality in family relationships. We assume that internality in family relationships can be both a resource of adaptation in a difficult life situation and also an additional cause of traumatization. In the control group, internality in family relationships is linked to the awareness of the own identity, but in groups of patients with ischemic heart disease is linked to the reliance on family resources. It can be said, that internality in family relationships requires psychological maturity of an individual. The analyzed situations of disease, disability and economic deprivation reduce control in the relationships, therefore, the possibility of obtaining family support becomes more problematic.

In recent years, much attention has been paid to the quality of economic justification of urban planning decisions, the impact of comfortable construction and living environment on the socioeconomic condition of municipalities. In this article, the authors have proposed an alternative method for predicting the socioeconomic efficiency of building neighborhoods and residential complexes, and justifying the effects this construction produces. The method can be applied to select the most effective projects from the point of view of municipal administration and consists in calculating tax revenues from the construction of residential complexes or entire neighborhoods, as well as the number of jobs that appear in new neighborhoods. It is recommended for municipalities that invest limited budget funds in the development of a particular territory on roads, networks, landscaping, etc. to compare urban development projects proposed by developers in terms of the effects they will produce, as well as the period of return of budget investments in the development of the territory due to tax revenues.

The purpose of this research is to find out the form of speech act of complaint by children character on “Stand by Me Doraemon” film and to describe complaint strategy that is used by the children to older people and among children. This research used illocutionary speech acts theory by Searle (1975) and theory of complaint strategies by Trosborg (1995). This research used descriptive qualitative method. The results found 30 data containing complaints by children's character to older people and among children either directly or indirectly. Based on Trosborg classifications, the complaint strategies found in this study can be categorized into four categories, including complaint strategy with no explicit reproach (4 data), complaint strategy with expression of annoyance or disapproval (17 data), complaint strategy with accusation (1 data), and complaint strategy with blaming (8 data). The findings also showed that the children character on this film mainly use complaining strategies with expression of annoyance or disapproval.

Published: January 2021

This study aims to compare students’ Japanese language grammar ability, between students who practice with a chatbot-based application (Gengobot) with students who do not use the application. This research was conducted using quantitative experimental research methods, with experimental class and control class. The subjects of this research were 22 Japanese language students. The results showed that the grammar ability of students who used Gengobot application as a training medium improved significantly than students who used conventional media as paper works. Factors that cause these differences are the use of cognitive and behavioristic approaches in applications, as well as the use of media, which is more practical and engaging. The questionnaire regarding student responses to the Gengobot application shows positive results. Things that need to be considered in future research are the development of the Gengobot application to be more flexible and to add more material to the application.
SLOW FOOD: FROM THE MOVEMENT TO THE CONCEPT OFTHE ENOGASTROMONIC TOURISM
Authors: Udovychenko V.
Published: January 2021

In the tourism sector of the economy, food is taking a high position during short-term’s and long-term travels, on the one hand, and also, on the other hand, the dangerous influence of fast-food is well known to the inhabitants of the Earth. That is why in this paper the key aspects of such activity as Slow Food were taken into account. It is important because Slow Food leads us against globalization, commercialization, and marketization of the world. The purpose of the article is to depict the key aspects of the Slow Food concept itself that developed from the social activists movement and nowadays is understood as the key unit of the enogastronomic tourism. The methods that were applied to the purpose of Slow Food study are quantitative analysis, literature knowledge and studying, method of “two steps”, comparative and geographical-comparative, historical, scientific syn­thesis, etc. The author’s point of view into the Slow Food existence can be depicted as one that transformed from the public social movement to the scientific concept of the enogastronomic tourism, and it is a result of the research accomplishment. Furthermore, the Slow Food movement essence is represented as a peculiar ecosystem and a route to the new way of people living, sustainable use of natural resources, complex cultural system, material and nonmaterial basis of the enogastronomic tourism. The movement strongly influences the rebuilding of the territorial linkages and the region sustainability, helps to balance the usage of the natural resources, and decrease the dangerous influence of human activities into the natural environment, leads to the cities rebranding and changes the tourist’s behavior in it.
The history, prerequisites, and place of Slow Food beginnings are briefly reviewed. The Slow Food movement as such one that widely spread all over the World through Slow Food-events application, thematic literature printing, academician community creation, and special education in the universities programs establishment is characterized. The key directions of the Slow Food activities are depicted. The key aspects of formation and development, the trajectory of Slow Food ideas movement, its transformation from an ideology into the scientific concept of the enogastronomic tourism are taken into account. The definition of “Slow Food” is given, and essential features of the concept are depictured. Also, the key theses and goals, principles and rules, the slogan, and agenda of Slow Food were reviewed.
At the same time, and this is the key importance of nowadays development and existence of the Slow Food concept, that there are some problems with the absence of strategic complex approach to its studying and development, and for its essential analysis. All of them could be mentioned as the perspective directions of future research and acquiring knowledge about it.

Many women now have complications in childbirth due to poor labor, which often threatens both mother and fetus. Also,the problem of prevention and treatment of premature uterine contractions is unresolved. Therefore, in this work we investigated the influence of ion channels as the end stage effectors of the regulatory cascades in the contractility of myometrium. To better understand the participation of TRPC4, TRPV4 and BKCa ion channels in myometrial contractility, we conducted experiments, keeping in mind the fact that changes in ionic conductivity of the plasma membrane regulate spontaneous and agonist-induced contractions. On the myometrial preparations of pregnant rats usingisolated tissue tensiometry, the amplitude of contractile force was recorded under the activation of these ion channels by their selective agonists. Obtained results allow us to consider (-) – englerin A as a way to stimulate uterine contractions in case of insufficient response to oxytocin, because at a concentration of 1 nM a significant increase in contraction force was developed and did not differ statistically from the response to oxytocin or carbacholin. The use of an agonist at concentrations of 30-100 nM causes some suppression of contractility. Based on the results describing the role of TRPV4 channels, namely the reduction of uterine smooth muscle contractions in response to their selective agonist GSK1016790A administration, we suggest that the main effect of activation of these channels depends on the expression and activity of adjacent calcium-dependent potassium channels. Our experiments found that the use of the liposomal form of quercetin to activate BKCa channels inhibits the excitability of myometrial cells more effectively than that dissolved in DMSO, which is promising for the correction of premature or excessive uterine activity.
