Authors: Kusniati Retno
Published: April 2021

Utilization of dental and oral health services characterized by interaction between patients who need health services and health care workers. The level of utilization of health services is very important since it could be an indicator of the occurrence of a type of health service the level of public awareness of dental and oral health. The level of utilization of dental and oral health services can be measured by the patient's perception of the services provided. An objective of this study was to investigate the relationship between levels of education and the perceived utilization of dental and oral health services at RSGM Unimus Semarang, Central Java. The project used an accidental sampling method with 76 subjects were recruited from RSGM Unimus Semarang. This research was conducted using a questionnaire designed to measure the factors of utilization of dental and oral health services. The results of the research using chisquare analysis showed that there was no significant relationship between the level of education (p = 0.089) and utilization of dental and oral health services at RSGM Unimus. Interestingly, respondents with a higher level of education had higher frequencies to utilize facilities at RSGM Unimus compared to respondents with lower level education.

In an increasingly standardized global society, there is a growing demand for differentiating elements of territories. Components such as natural and built heritage, culture, history and traditions are thus understood as distinguishing, conferring notoriety and competitiveness. In Portugal, the low density areas, depressed or fragile, are in this horizon, the ones that can benefit most from this unprecedented, due to the urgency they show in attracting people and the indisputable need to generate development, create sources of wealth and opportunities. Based on this argumentation, the development strategies anchored in the preservation and sustainable valorization of the endogenous and inimitable resources of the territories, to which innovation, creativity and scale, should be increasingly prioritized. This study aims to highlight the processes of territorial development that are related to public policies that affect the potentialities of the territory of the municipality of Mértola [Portugal]. Thus, it is concluded that there is a greater need and involvement of all local tourism agents, as well as an increase in the incentive for the entire population to boost this increasingly important "engine" of economic and social development in this territories.

Tourism in São Francisco de Paula, in Rio Grande do Sul [Brazil] has stood out and, due to its wide territory, the need to organize tourism in rural areas emerges. Otherwise, socioeconomic and environmental sustainability may be weakened, if the presence of tourism activity is disordered. Thus, tourist routing can be an ally in promoting local, sustainable development. Therefore, the objective of this study was to develop a roadmap for rural tourism in São Francisco de Paula. The first step towards achieving this goal involved examining documents to obtain an overview of local tourism. The next two stages took place through a specific questionnaire addressed to entrepreneurs and tourists. Based on the data collected, an instrument for sustainable regional development was developed: a rural roadmap called ‘Encantos de São Chico’. The survey shows that both owners and tourists recognize the relevance of rural tourism to sustainable local development.
A new record of Paramylodon harlani (Owen 1840) (Xenarthra, Pilosa, Mylodontidae) from the late Pleistocene of Valsequillo, Puebla, with comments on its paleobiogeography and paleoecology in Mexico

Published: April 2021

Paramylodon harlani was a large ground sloth recorded across North America, from Canada to Mexico. In Mexico, it is known from several late Pleistocene localities, but most of these records just mention the taxon in passing and few specimens have been described or illustrated. In this work, we describe a left tibia from the Valsequillo Basin, Puebla state. Its morphology and measurements allowed us to identify it as Paramylodon harlani, adding a new record for Mexico. In Mexico, P. harlani occurred mainly in the Trans-Mexican Volcanic Belt, central Mexico, with some records in the north and southeastern part of the country. Most localities are located between 1500 to 2000 m.a.s.l. Paleoenvironmental and paleoclimatic inference in some localities of Mexico where P. harlani occurred, showed heterogenous vegetation dominated by grasslands, and agree with the preferred habitat proposed for this species based on localities in the United States. This indicates that P. harlani could inhabit different environments, from grasslands to more wooded areas, and this adaptation allowed it to extend its range from the north to the southeast of Mexico.
Reply to “Porphyry-related high-sulfidation mineralization early in Central American Arc development: Cerro Quema deposit, Azuero Peninsula, Panama” by Corral (2021)
Authors: Perelló José , Creaser Robert A. , García Alfredo
Published: April 2021

Dear Editor, we thank Corral (2020) for his anticipated interest in our paper on the timing of the porphyry-related high-sulfidation epithermal mineralization at Cerro Quema in the Azuero peninsula of southwestern Panama. Our study, based on three Re-Os ages for molybdenite intimately associated with Cu-bearing sulfide minerals from the hypogene roots of the La Pava center (Figure 1), shows that the main event of high-sulfidation Cu mineralization took place during the earliest Maastrichtian at ~71 Ma. The reported ages, together with the geologic relationships described in our paper (Perelló et al., 2020), plus a series of regional geologic, structural, petrochemical, and geotectonic considerations, not only precisely date the porphyry-related nature of the Cerro Quema high-sulfidation mineralization, but are also significant in that they confirm the rapid evolution of the earliest stages of the Central American Arc – from subduction initiation at 75-73 Ma to arc stability and maturation at 71 Ma (e.g., Buchs et al., 2011a and references therein) – and place the mineralization in a regional geodynamic setting. Irrespective of the regional geologic arguments reiterated by Corral (2020) in support of his previous genetic interpretation (e.g., Corral et al., 2016) and to invalidate our conclusions, Corral´s real concern is the reliability of our molybdenite ages, which are much older than his preferred age of mineralization for Cerro Quema. We believe that many of the points raised by Corral (2020), including the regional and local geologic backgrounds of the deposit and the dated samples, were properly addressed in Perelló et al. (2020), and that it would be redundant to repeat them here. Additional petrochemical evidence in support can be found in Whattam and Stern (2015, 2020) and Whatam (2018).

Icriobranchiocarcinus rodas Vega n. sp., is recorded from lower Maastrichtian (Upper Cretaceous) Arroyo Grande Formation near the town of Rodas (Central Cuba). I. rodas Vega n. sp. represents additional evidence of paleobiogeographic affinities between Chiapas (SE Mexico) and Cuba, during the Late Cretaceous. The genus Icriobranchiocarcinus Vega, 2018 in Vega et al., 2018 was erected from the type species Icriobranchiocarcinus tzutzu Vega, 2018 from the lower Maastrichtian Ocozocoautla Forma-tion (Chiapas). I. rodas Vega, n. sp. preserves details of ventral morphology as well as more details of chelipeds not reported in I. tzutzu, adding to the morphology of the genus. Icriobranchiocarcinus belong to a family (Lythophylacidae Van Straelen, 1936) that became extinct worldwide during the K/Pg event.
Estimation of a Thermal Conductivity in a Stationary Heat Transfer Problem with a Solid-Solid Interface
Authors: Umbricht Guillermo Federico , Rubio Diana , Tarzia Domingo Alberto
Published: April 2021

An inverse problem for a stationary heat transfer process is studied for a totally isolated bar on its lateral surface, made up of two consecutive sections of different, isotropic and homogeneous materials, perfectly assembly, where one of the materials, that is unreachable and unknown, has to be identified. The length of the bar is assumed to be much greater that the diameter so that a 1D heat transfer process is considered. A constant temperature is assumed at the end of the unknown part of the rod while the other end is let free for convection. We propose a procedure to identify the unknown material of the bar based on a noisy flow measurement at the opposite end. Necessary and sufficient conditions are derived together with a bound for the estimation error. Moreover, elasticity analysis is performed to study the influence of the data in the conductivity estimation and numerical examples are included to illustrate the proposed ideas and show the estimation performance.
Heat Analysis and Fire Prevention of Timber Buildings in Southwest China Based on Fractal and Seepage Theory
Authors: Cao Yingchun , Chen Xiaoling , Yang Jie , Zhang Haoyan
Published: April 2021

In traditional settlements in Southwest China, there are many timber historical buildings and residential buildings, which feature a low fire resistance rating. The preservation and inheritance of these timber buildings are mainly threatened by fire. However, the existing research has not explored the deep correlation between the spatial structure of settlements and fire. To make up for the gap, this paper aims to find the ideas and measures that effectively prevent the fire from occurring in timber buildings of traditional settlements in Southwest China, based on fractal and seepage theory. Firstly, the fractal features were extracted from the spatial structure of these settlements. Then, the authors identified the factors affecting the spread of fire in buildings, and analyzed the mechanism of fire propagation between the timber buildings of traditional settlements. On this basis, a fire prevention scheme was proposed, which integrates the “targeted control of overall structure” with “comprehensive synergy between multiple local elements”. The research results provide a reference for applying fractal and seepage theory in the fire prevention of other buildings with special structures.
Thermodynamic Analysis of Hydrogen Production by a Thermochemical Cycle Based on Magnesium-Chlorine
Authors: Bensenouci Ahmed , Teggar Mohamed , Medjelled Ahmed , Benchatti Ahmed
Published: April 2021

Most thermochemical cycles require complex thermal processes at very high temperatures, which restrict the production and the use of hydrogen on a large scale. Recently, thermochemical cycles producing hydrogen at relatively low temperatures have been developed in order to be competitive with other kinds of energies, especially those of fossil origin. The low temperatures required by those cycles allow them to work with heats recovered by thermal, nuclear and solar power plants. In this work, a new thermochemical cycle is proposed. This cycle uses the chemical elements Magnesium-Chlorine (Mg-Cl) to dissociate the water molecule. The configuration consists of three chemical reactions or three physical steps and uses mainly thermal energy to achieve its objectives. The highest temperature of the process is that of the production of hydrochloric acid, HCl, estimated between 350-450℃. A thermodynamic analysis was performed according to the first and second laws by using Engineering Equation Solver (EES) software and the efficiency of the proposed cycle was found to be 12.7%. In order to improve the efficiency of this cycle and make it more competitive, an electro-thermochemical version should be studied.

Overfishing can occur in open access fisheries, where fishermen conduct fishing activities without restrictions. Fisheries management based on biological factors alone (Maximum Sustainable Yield approach) is considered inadequate because it does not consider socio-economic aspects in fisheries management. The study aims to analyze the utilization of small-scale fishery resources in Semarang City and determine its policies to be sustainable. Bioeconomic analysis was used to optimize the utilization of fishery resources. Small-scale fisheries management strategic policies, used analysis of Interpretative Structural Modeling (ISM). The results showed utilization of small scale fishery resources in Semarang City can be achieved with optimal production of anchovy (Stolephorus spp.) 1,477.79 tons/year and optimal effort of 324 units; optimal production of Tembang (Sardinella fimbriata) 235.96 tons/year and optimal effort of 516 units; optimal production of mackerel (Rastrelliger kanagurta) 28.51 tons/year and optimal effort of 479 units; and optimal production of Petek (Leiognathus sp.) 25.54 tons/year and optimal effort of 847 units. In conclusion, the Anchovy (Stolephorus spp.) resources have experienced overfishing since 2007-2008; Mackerel (Rastrelliger kanagurta) resources overfishing occurred from 2009-2015; and Petek (Leiognathus sp.) resources have experienced overfishing since 2014-2016; while Tembang (Sardinella fimbriata) resources have not experienced overfishing because they are not the main target. The key sub-elements of small-scale fisheries management in Semarang City include: a) fishermen; b) Semarang City Fisheries Agency; c) overcapacity; d) decreasing catches; e) environmentally unfriendly arrests; f) ineffective regulation; g) conservation fish resources; h) increasing fishermen's income; i) limitation environmentally unfriendly fishing gear.

Published: April 2021

The Citarum watershed is one of the priority watersheds due to problems of critical land, flooding, erosion, and sedimentation which continue to increase every year. As the main catchment area that contributes to maintaining the availability of water resources, the upstream Citarum watershed continues to experience a reduction in forest and an increase in built-up land. A research aimed to analyze land use changes to the hydrological characteristics was carried out at the Watershed. The methods used include interpretation of SPOT image data, analysis of land use changes, and determining the values of KRA and KAT. The results of the analysis of land use change conditions in 2009-2018 saw a reduction in forest area (-5.5%), rice fields (-17.4%), and shrubs (-60.8%). Land use increased in built up land (39.7%), dry land agriculture (13%), plantations (6.4%), and open land (95.5%). The highest discharge occurred in 2010 at 606,3 m3/second and the lowest discharge in 2012 was 4,3 m3/second. The KRA and KAT values of the Upper Citarum watershed were moderate and very high. The multiple linear regression model of the relationship between land use changes that affect river flow fluctuations is Y = 2380.5 + 0.9 rainfall -206.5 forest + 6.1 build-up area -31.8 dryland agriculture + e. Other factors that influence the increase in river discharge are the slope of land slopes, rainfall patterns, and inadequate land use methods.

The main cause of flooding and erosion that creates critical land in various regions in Indonesia is surface runoff. The surface runoff will occur if rainfall exceeds the capacity of soil water absorption (infiltration capacity). The soil management of each land use could improve the infiltration capacity. The water movement both on the surface and in the soil determines the water infiltration. This study predicts surface runoff based on the infiltration rate of various land uses and rainfall in the Ciliwung Watershed. A series of studies were performed in the upstream and middle areas of the watershed. Observations of soil properties, water movement, and rainfall were carried out in various dry land uses. The results showed that the soil's physical properties mostly determine the constant infiltration rate, which affected the water movement in the ground. The initial water content, the degree of saturation of the initial moisture content, and the soil's physical properties determine the time of constant infiltration rate. The value of constant rate infiltration and the time of its achievement define the amount of surface runoff that occurs.

Of Church Orders and Postmodernism
Authors: Benedict Philip
Published: April 2021

Self-avowedly influenced by the postmodernist critique of nineteenth-century ‘positivism’, Jesse Spohnholz's ambitious and multiple prize-winning 2017 The Convent of Wesel: The Event that Never was and the Invention of Tradition speaks at once to the political and institutional history of the Reformed churches of the Netherlands and northwestern Germany, to the role of archiving practices in shaping historical understanding, and to the nature of historical study. This review offers both an extended synopsis and a critique of the book. While recognizing its considerable achievement, it questions its framing of its findings about the Reformation era with reference to the ‘confessionalization’ debate, its reliance on a prefabricated narrative about archives as instruments of power and marginalization, and its mischaracterizations of post-Rankean historical practice and theory. Implications of the book’s findings for further research into the politics and personalities of the Reformation in the Low Countries are also suggested.

Learning from Ecology: a Systemic Skill Management Approach for the Innovation Economy
Authors: Setti Stefano
Published: April 2021

«Digital and non-cognitive skills are becoming increasingly necessary to seize emerging job opportunities». In the Industry 4.0 era, that can conveniently be redefined in a broader approach as Innovation Economy, beside the technological issues the international community has recognized that People and Processes must be developed as well. Artificial Intelligence is quite mature - not banished anymore in research laboratories, but embedded in most application used from billions of people - and more and more jobs will be completely transformed by automation. So the skill management challange is becoming even more crucial and cannot be faced at a private/local level anymore: an ecosystemic approach is needed. Ecology metaphores and lessons are easy to understand and to apply to other knowledge areas, that's why we can try to derive a new paradigm from that to draw a new skill management systemic approach.
Is Capital Structure Important in Contemporary Finance Relations?
Authors: Učkar Dean
Published: April 2021

t The various combinations of sources of financing that a business uses in its operations have multiple impacts on the generation of its cash flow. Such influence can be viewed from the aspect of forming the total cost of financing the company, from the aspect of investments where such an indicators represents the minimum level of required profitability of investment projects, as well as from the aspect of investors in an enterprise where different capital structure carries with it a different level of financial risk. It is therefore not surprising that there is considerable scientific interest in this issue and numerous researches conducted on this topic. Moreover, the relevance of the subject is also evidenced by the fact that there are numerous theories on the formation of capital structure and its consequences on the valuation of the company, that is, the influence on the market value of the company's shares. This paper will determine the average values of the formation of the capital and financial structure of Croatian companies listed on the Zagreb Stock Exchange. The analysis of 30 companies over a ten-year period from 2009 to 2018 will seek to show the impact that the formed capital structure has on profitability. By establishing a negative link between the selected debt indicators and the profitability indicators, the validity of contemporary capital structure theories, which have their starting point in behavioral finance and are specific for developed financial markets, has been rejected.

Cilj raziskave je predstaviti turistične informacijske centre (TIC) in ugotoviti njihovo vlogo pri ponudbi informacij za ljudi s posebnimi potrebami. TIC-i igrajo pomembno vlogo pri upravljanju tržnih in promocijskih dejavnosti za turistične destinacije. Osebje v TIC-ih je glavni vir informacij za turiste. Večino so v preteklosti TIC-i svoje informacije obiskovalcem delili osebno. V sodobnem času je vedno večji vpliv informatizacije. Pojav spletnega in oblačnega dostopa prek mobilnih naprav je ponovno preučil tradicionalno vlogo TIC-ov. Nekateri ugotavljajo negativno razmerje med splošno uporabo interneta in povpraševanjem po obisku turističnih informacijskih centrov. Uporabniki družbenih medijev pogosto iščejo informacije tudi na klasičen način. Hiter razvoj informacijske komunikacijske tehnologije je spodbudil odločevalce na lokalni in državni ravni, da skrbno preučijo trenutno organiziranost in vlogo ITC-ov. Ugotavlja se, da so turisti, ki obiskujejo TIC-e manj občutljivi kot skupina, ki ne obiskuje na napredno informacijsko komunikacijsko tehnologijo in bolj zadovoljna z razpoložljivostjo signalov WIFI za lažjo uporabo osebnih mobilnih naprav ali prenosnih računalnikov. Tako bo potrebno ljudem s posebnimi potrebami prilagoditi storitve, saj postajajo pomembna skupina v turizmu.

Podkožni mikročipi v zadnjem času postajajo realnost in ne več znanstvena fantastika. Uporabljajo se na različnih področjih, za različne namene in so vedno bolj razširjeni. Prispevek predstavlja primerjavo rezultatov mednarodno izvedene ankete, s katero smo želeli ugotoviti, v kakšen namen in pod kakšnimi pogoji bi si bili posamezniki pripravljeni vstaviti pasiven podkožni RFID NFC mikročip. Presenetljivo, navkljub kulturnim razlikam med primerjanimi državami (Poljska, Češka, Hrvaška in Slovenija) v veliko primerih ni bilo statistično značilnih razlik med odgovori. Rezultati so pokazali sorazmerno velik delež tistih, ki bi uporabljali mikročip za zdravstvene namene (57%), za ostale namene pa je bil delež manjši. Anketiranci v obravnavanih državah različno ocenjujejo svoje poznavanje RFID tehnologije. Pripravljenost za uporabo pasivnega podkožnega mikročipa, ki ne bi omogočal sledenja in GPS pozicioniranja, se prav tako razlikuje med posameznimi državami. Na osnovi slednjega lahko ocenimo, v kolikšni meri je posameznikom pomembno vprašanje zasebnosti.
An increased proportion of transgenic plants in the progeny of rapeseed (Brassica napus L.) transformants
Authors: Raldugina G. N. , Hoang T. Z. , Ngoc H. B. , Karpichev I. V.
Published: April 2021

Cotyledon and leaf explants of two spring rapeseed varieties were transformed with Agrobacterium tumefaciens harboring a genetic construct with the gfp marker gene. In order to reduce the proportion of hyperhydrated shoots, which appeared during regenerant formation, we optimized sucrose content in the regeneration media. Analysis of the progeny obtained from T0 regenerants showed that in a number of lines the distribution of the gfp marker did not follow Mendelian segregation of a monogenic trait in self-pollinated plants, while in the progeny of the other lines of transgenic plants, the gfp marker was completely absent, although its presence had been confirmed in all selected T0 plants. We also found that in individual transformants gfp is randomly inherited throughout the central peduncle; its presence in the genome of seedlings does not depend on the location of the pod. Thus, both transformed and non-transformed cells were involved in the formation of gametes in T0 plants. In addition, marker segregation was different in plants of the T1 line obtained by nodal cuttings of a primary transformant, depending on the location of the cuttings on the stem of the original plant, indicating that the nature of T1 generation plants was also chimeric. Furthermore, we showed that propagation of plants by cutting followed by propagation by seeds formed as a result of self-pollination led to an increase in the proportion of transgenic plants in subsequent generations. The results obtained during the course of this study show that the transformants were chimeric, i. e. their tissues contained both transgenic and non-transgenic cells, and this chimeric nature was passed on to subsequent generations. We found that, in addition to nutrient media composition, other factors such as plant genotype and explant type also contribute to the rising of chimeric plants during transformation. Based on these results, we developed a simplified method, which consists of several rounds of a combination of cutting, seed production by self-pollination, and subsequent culling of wild-type plants, which significantly enriched descendent populations of the original rapeseed transformants with plants transgenic for the gfp marker.

Актуальность. Создание новых технологий утилизации теплоты дымовых газов, образующихся в различных металлургических процессах и при сжигании органических топлив на тепловых электростанциях, невозможно без развития фундаментальных знаний процессов теплопереноса в энергоэффективных надежных термодинамических системах на базе термосифонов. Актуальность исследования процессов теплопереноса в относительно тонком (толщиной не более 10 мм) слое теплоносителя в испарителе термосифона обоснована необходимостью разработки математических моделей более простых по сравнению с моделями на базе уравнений Навье–Стокса, или учитывающих только механизм теплопроводности. Цель: оценка вклада термогравитационной конвекции в процесс теплопереноса в малом по толщине слое жидкости в условиях, характерных для нижней крышки термосифона – при нагреве нижней поверхности слоя и испарении его с верхней поверхности. Методы. Теневым методом установлены траектории трассеров в слое жидкости. Регистрация перемещений трассеров проводилась Particle Tracking Velocimetry методом с использованием специальной системы визуализации. Задача теплопроводности в слое жидкости решена методом конечных разностей. Результаты. По результатам экспериментальных исследований теплопереноса в слое жидкости малой толщины в условиях, соответствующих по основным значимым факторам нагреву теплоносителя на нижней крышке термосифона, установлено влияние плотности теплового потока, толщины слоя жидкости, свойств теплоносителя на температуры и скорости в этом слое. Установлено, что рост теплового потока и толщины слоя теплоносителя приводят к интенсификации циркуляционных течений. Показано, что в ламинарном режиме течения (Ra=103÷5·105) интенсивность процессов теплопереноса в слое этанола выше, чем в воде. Установлено, что в малом по толщине слое жидкости (от 3,2 до 7,4 мм) процесс термогравитационной конвекции интенсивнее процесса теплопроводности.

В статье рассматриваются мероприятия, направленные на снижение экологически вредных выбросов оксидов азота при сжигании кузнецких углей марки Д на энергетических котлах типа Е-240-13,8-560КТ (заводское обозначение ПК-114) применительно к строящейся тепловой электростанции в Калининградской области. Целью исследования является разработка комплекса технических мероприятий для внедрения на вновь вводимых в работу энергетических котлах по горелочным устройствам, топкам котлов и системам пылеприготовления, способствующих не только низкоэмиссионному сжиганию кузнецких углей марки Д, но и обеспечивающих требуемые технико-экономические показатели. Объектом исследования являются топочные процессы, горелочные устройства энергетических котлов и системы пылеприготовления. Методом исследования является математическое моделирование топочных процессов. Актуальность данной работы обусловлена важностью обеспечения соответствия экологическим нормам, в частности нормам выбросов оксидов азота NOx, вновь вводимого в работу энергетического оборудования. Рассмотренные в статье технические мероприятия выбраны по результатам численного моделирования топочного процесса и расчета таких его параметров, как поля температур, концентраця дискретной фазы и содержание кислорода на различных высотных отметках и сечениях при варьируемых исходных данных (включая расположение сопл третичного дутья, перераспределение воздуха по горелкам и т. д.). Итогом исследования явился обоснованный выбор одного из них в качестве рабочего варианта.

The article deals with the main problems of handling transit trains at a large out-of-class sorting station of the Sverdlovsk railway Yekaterinburg-Sortirovochny. The analysis of all possible current problems in the promotion of transit cargo was made, and promising ways of solving them are developed and proposed. The Yekaterinburg-Sortirovochny station has a huge potential and plays an important role in the international relations of modern Russia with China, as it is located within the Eurasian Transport Corridor connecting Moscow and Beijing. At present, the speed of cargo handling and delivery in transit trains within the transport corridor also affects the strengthening of international relations. It is concluded that it is necessary to reduce the downtime of transit trains at the station and introduce a new structure for their handling.

Published: April 2021

The research is devoted to the storage and distribution of bread stocks in the sovereign residents of the fortress city of the eastern section of the Belgorod line in the second half of the 17th century. To analyze the set problems, information about bread stocks preserved in the inventory of cities compiled in 1678 is used. This document reflects information on all the cities of the Belgorod line and its neighboring counties in the context of a single time segment, which makes it possible to determine the general patterns of the distribution of bread stocks. During the study, a description was given of the structure and composition of granaries located in the fortresses of the eastern section of the Belgorod line. This allowed us to answer questions about the number of animal heads, tax collectors and clerks, as well as their social affiliation. It was determined that the bulk of the bread stored in the living yards was rye and oats, which could serve as a bread salary issued to service people, as well as grain sent to other cities and to the Don. In addition, the presence in sovereign dwellers of reserves of agricultural crops such as wheat, barley, buckwheat and millet, as well as grain processing products: rye and oat flour (thick) is revealed. It is established that the filling of living yards was uneven. Particular attention was paid to the study of the variability of the distribution of bread reserves in the inhabitants of the eastern section of the Belgorod line, in relation to the number of service garrisons, and the strategic importance of the bread reserves stored in sovereign residents and their influence in the development of the county land fund is determined.

The study is devoted to the problem of terminological confusion in the concepts of “rhythmic gymnastics” and “classical aerobics”. We present a comparative description of two types of motor activity: rhythmic gymnastics and classical aerobics. The comparison is carried out for 12 criteria: the content of the classes (equipment); specific exercise technique; the physical qualities developed in the classroom; method of exercise; the structure and content of parts of lessons; music; methods of constructing combinations of the motor; pedagogical control; the predominant nature of the energy supply of muscle activity; requirements for equipment; equipment of the hall; instructor’s commands. On the basis of the conducted pedagogical experiment, the methods of the effectiveness of rhythmic gymnastics and classical aerobics is shown. Changes in the indicators of physical fitness of high school students taking part in the experiment are revealed.
Periphrases as a form of thinking
Authors: Du Chunyang
Published: April 2021

We attempt to consider the reproduction of the meaning of the word HOME in the periphrastic constructions used in the Russian translations of the poem by the Chinese poet Li Bai. Based on analysis of six translations of the poem “Quiet Night Thought” we prove that periphrastic unit is not only used instead of the name of the object, but with the name of the object. We establish that in the translations of the poem by the Chinese author, the periphrastic names representing the concept of HOME reflect the form of thinking due to the semantics read at the nonverbal level. The periphrastic unit HOME is an analogue of the microcosm and macrocosm, transmitting neutral interpretations, which allows the periphrase to convey a relatively complete descriptive meaning, since by its semantics it strives to form a single semantic concept of the concept of “home”. We substantiate that cultural information is not included in the semantic minimum of the sign and may be irrelevant in practice, but the periphrase, as a secondary sign, always has connotations that are especially important in the reflective flow of speech, when the factor of un-derstanding a written translated text is not only decoding of the written text, but also the interpretation of the communicative settings of information of the original text creator.

Published: April 2021

Is devoted to the study of the concept of “happiness” based on the novel by Elizabeth Gilbert “Eat. Pray. Love”. The object of the study is fiction travel literature. The subject is the concept of “happiness” and its translation features from English into Russian. The purpose of this study is to identify typical cognitive models “happiness is...” and to study the translation features of fiction travel literature. The study identified and analyzed the cognitive models that make up the concept of “happiness” in the analyzed novel: 1) enjoyment of food; 2) search for peace of mind and your inner “I”; 3) love; 4) obtaining new knowledge; 5) travel; 6) being alone. The corpus of examples is 100 units. The analysis of the factual material showed that the most frequent grammatical transformations include grammatical substitutions; the most popular lexical and semantic transformations are modulation and concretization; omissions and additions make up the most commonly used additional translation transformations. Based on the analyzed linguistic units, we conclude that the cognitive model laid down by Elizabeth Gilbert in the concept of “happiness” in American culture is reflected in other cultures as well, representing a universal value.

Published: April 2021

The work is devoted to the description of one of the modern research methods in linguistics – modeling. We present theoretical material about modeling and substantiate the idea that this method is an effective way of analyzing and interpreting information of not only scientific, but also artistic type. The purpose of the work is an attempt to study and describe the modeling me-thod based on the conceptosphere of Russian-speaking writers in Kazakhstan. In this regard, we define our attitude to the concepts of the concept and conceptosphere. The modeling method is considered as a way to highlight the structural features of a concept, based on its definition as a conditionally mental structure that does not exist outside of thinking. The results of the analysis lead to the conclusion that systemic research in this area is promising.
