Published: December 2021

Работа посвящена исследованию гамма-фона в городской среде Петропавловска-Камчатского (Камчатский край), а именно в парках и зонах отдыха. Измерения мощности поглощенной дозы проводились на разработанном коллективном Томского политехнического университета (ТПУ) дозиметре с использованием органического сцинтиллятора ВС-408, который является схожим по техническим характеристикам с БДКГ-01. С целью вычисления поправочного коэффициента для перевода показаний дозиметра из имп/с в нЗв/ч был проведен ряд калибровочных измерений с точечными источниками гамма-излучения – 60Co и 137Cs. Разработанным дозиметром проводились измерения длительностью не менее 5 минут в различных районах города Петропавловска-Камчатского, особое внимание уделялось исследованию объектов техносферы
из материалов, являющимися природными источниками повышенного гамма-излучения. Исследования показали, что памятник В. И. Ленину и стела «Город воинской славы» в центре города Петропавловска-Камчатского содержат граниты у их основания, которые дают завышенный гамма-фон

The work is devoted to the study of the gamma background in the urban environment of Petropavlovsk-Kamchatsky (Kamchatka Territory), namely in parks and recreation areas. Measurements of the absorbed dose rate were carried out on a scintillation organic dosimeter developed by the team of the Tomsk Polytechnic University (TPU), which is a more budgetary analogue of the BDKG-01. In order to calculate the correction factor for converting the dosimeter readings from impulses/s to nSv/h, a number of calibration measurements were carried out with point sources of gamma radiation – 60Co and 137 Cs. The developed dosimeter carried out measurements with a duration of at least 5 minutes in various districts of the city of Petropavlovsk-Kamchatsky, special attention was paid to the study of technosphere objects made of materials that are natural sources of increased gamma radiation. Studies have shown that the monument to V. I. Lenin and the stele « City of Military Glory » in the center of the city of Petropavlovsk-Kamchatsky contain granites at their base, which give an overestimated gamma background.

Published: December 2021

Представлено сравнительное моделирование зон относительных сдвиговых деформаций для четырех камчатских землетрясений с Mw ≥ 4.8, произошедших в период с декабря 2018 г. по март 2021 г., основанное на статической модели деформационного поля в рамках теории упругости. Земная кора рассмотрена как однородное изотропное упругое полупространство, в котором присутствуют различные источники напряжения, описывающие очаг землетрясения: точечный источник в виде единичной силы, точечный источник в виде комбинации девяти двойных сил, распределенный источник в виде прямоугольной площадки.

We present a comparative modeling of the zones of relative shear deformation for four Kamchatka earthquakes Mw≥4.8 that occurred between December 2018 and March 2021. Modeling based on a static model of the deformation field in the framework of the theory of elasticity. The Earth’s crust is considered as a homogeneous isotropic elastic half-space, in which there are different sources of stress describing the source of the earthquake: a point source in the form of a single force, a point source in the form of a combination of nine double forces, a distributed source in the form of a rectangular area.

The purpose of this study was to determine the effect of the Inside Outside Circle (IOC) cooperative learning model on the learning outcomes of eighth grade students of SMP Negeri 4 Metro. The method that will be used in this study is a true experimental design using a pretest-posttest control group design. This research was conducted by 22 students of class VIII B SMP Negeri 4 Metro even semester as samples. After receiving treatment using the Inside Outside Circle (IOC) type of cooperative learning model, student learning outcomes have increased seen from the comparison in the pretest and posttest evaluations, namely students who achieve KKM in the pretest evaluation are 27.27% or 6 students from a total of 22 students. While the students who achieved the KKM in the posttest evaluation were 68.18%, namely 15 students from a total of 22 students. This is evidenced again by the calculation of data analysis using the Simple Linear Regression formula obtained = 55.5505+ b = 0.3183 so that Y = + bx is( Y) =55.5505+0.3183x and the analysis calculation that t_hitung> t_tab which is seen at a significant level of 5%, namely 2.90 > 1.72. And at a significant level of 1%, namely 2.90> 2.53. Which can be seen in the table G statistics. Thus, the hypothesis is accepted. So it can be concluded that "there is a positive influence of the Inside Outside Circle (IOC) type of cooperative learning model on the learning outcomes of class VIII students of SMP Negeri 4 Metro in even semesters"

Optical imaging of changes in membrane potential of living cells can be achieved by the means of fluorescent voltage sensitive dyes (VSDs). A particularly challenging task is to efficiently deliver these highly lipophilic probes to specific neuronal subpopulations in brain tissue. We have tackled this task by designing a solubilizing, hydrophilic polymer platform that carries a high-affinity ligand for a membrane protein marker of interest and a fluorescent VSD. Here, we disclose an improved design of polymer supported probes for chemical, non-genetic targeting of voltage sensors to axons natively expressing the dopamine transporter in ex vivo mouse brain tissue. We first show that for negatively charged rhodol VSDs functioning on the photoinduced electron transfer principle, poly(ethylene glycol) (PEG) as a carrier enables targeting with higher selectivity than the polysaccharide dextran in HEK cell culture. In the same experimental setting, we also demonstrate that incorporation of an azetidine ring in the rhodol chromophore substantially increases the brightness and voltage sensitivity of the respective VSD. We show that the superior properties of the optimized sensor are transferable to recording of electrically evoked activity from dopaminergic axons in mouse striatal slices after averaging of multiple trials. Finally, we suggest the next milestones for the field to achieve single-scan recordings with non-genetically targeted VSDs in native brain tissue.

Published: December 2021

Modern life-style is creating an indoor generation: human beings spend approximately 90% of their time indoors, almost 70% of which is at home – this trend is now exacerbated by the lockdowns/restrictions imposed due to the COVID-19 pandemic. That large amount of time spent indoors may have negative consequences on health and well-being. Indeed, poor indoor air quality is linked to a condition known as sick building syndrome. Therefore, breathing the freshest air possible it is of outmost importance. Still, due to reduced ventilation rates, indoor air quality can be considerably worse than outdoor. HVAC, air filtration systems and a well-ventilated space are a partial answer. However, these approaches involve only a physical removal. Photocatalytic mineralisation of pollutants into non-hazardous, or at least less dangerous compounds, is a more viable solution for their removal. Titanium dioxide, the archetype photocatalytic material, needs UVA light to be “activated”. However, modern household light emitting diode lamps irradiate only in the visible region of the solar spectrum. In this short-communication, we show that the surface of titanium dioxide nanoparticles modified with copper oxide(s) and graphene shows promise as a viable way to remove gaseous pollutants (benzene and NOx) by using a common light emitting diode bulb, mimicking real indoor lighting conditions. Titanium dioxide, modified with 1 mol% CuxO and 1 wt% graphene, proved to have a stable photocatalytic degradation rate, three times higher than that of unmodified titania. Materials produced in this research work are thus strong candidates for offering a safer indoor environment.

INTERPRETASI KARAKTER HEWAN DALAM FABEL: KAJIAN HERMENEUTIKA
Authors: Nasution Hasnawati
Published: December 2021

AbstrakFabel merupakan cerita yang diperankan oleh hewan, tetapi karakteristik hewan tersebut adalah sifat manusia. Cerita fabel sering juga disebut cerita moral karena pesan yang ada di dalam cerita fabel berkaitan erat dengan moral. Sifat hewan tesebut juga berkaitan dengan bentuk fisik dan sifat hewan tersebut di alamnya. Penelitian ini bertujuan mengiterpretasikan karakter yang diperankan hewan dalam fabel dengan sifat sesungguhnya pada hewan tesebut. Kajian interpretasi pada fabel ini menggunakan toeri hermeneutika Gadamer yang menggabungkan dialektis dan histori. Berdasarkan analisis yang dilakukan dapat dismpulkan bahwa ada hubungan dan persamaan antara karakter hewan di dalam fabel dengan sifat manusia yang diperankannya dalam cerita tersebut. Hewan buas memerankan karakter manusia yang kuat dan berkuasa bahkan terkadang menyakiti hewan yang lemah. Hewan kecil seperti kancil memerankan sifat dan karakter manusia yang cerdik yang terkadang sifat cerdiknya yang dapat mengalahkan hewan yang kuat. Oleh karena itu, karakter hewan disesuaikan dengan karakter manusia yang diperankannya. Hewan buas sebagai metafor manusia yang jahat dan hewan kecil dan cerdik sebagai metafor masyarakat biasa yang cerdas. AbstractFables are stories that are played by animals, but the characteristics of these animals are human nature. Fable stories are often called moral stories because the messages in fable stories are closely related to morals. The nature of the animal is also related to the physical form and nature of the animal in its nature. This study aims to interpret the characters played by animals in the fable with the real characteristics of these animals. The interpretation of this fable uses Gadamer's hermeneutic theory which combines dialectical and historical. Based on the analysis carried out, it can be concluded that there are relationships and similarities between the animal characters in the fable and the human nature they play in the story. Wild animals portray human characters who are strong and powerful, sometimes even hurting weak animals. Small animals such as the mouse deer portray the nature and character of a clever human who sometimes can beat strong animals.

Published: December 2021

Objetivou-se com este trabalho avaliar o efeito da diminuição de farinha de peixe em dietas com níveis de proteína bruta sobre o desempenho zootécnico, eficiência de retenção de nutrientes e histologia do intestino de tilápia do Nilo (Oreochromis niloticus). Foram utilizados 180 alevinos de tilápia com o peso inicial de 1,17 ± 0,05 g, distribuídos em 18 aquários por um período de 75 dias. Os resultados foram analisados por meio de um Delineamento Inteiramente Casualizado - DIC, com seis tratamentos em esquema fatorial 3x2, correspondendo três níveis de proteína bruta das dietas (20%, 24% e 28%) e dois níveis de inclusão de farinha de peixe - FP (25% ou 50% do nível de proteína da dieta), com três repetições. Quando a análise de variância mostrou diferenças significativas entre tratamentos, as médias foram comparadas pelo teste Tukey. Foram avaliados o desempenho de produção e a eficiência de retenção de nutrientes e as alterações na histologia e altura das vilosidades intestinais. O aumento de proteína na dieta proporcionou aumento no ganho em peso e na taxa de crescimento específico. As dietas com níveis de proteína de 28% promovem balanço de nutrientes ao ponto de diminuir a inclusão de farinha de peixe (25%), refletindo em melhores índices de desempenho produtivo e adaptações na morfologia do trato digestórios de tilápia do Nilo. As alterações histomorfométricas estão relacionadas à alimentação fornecida e representam uma resposta adaptativa ao metabolismo. Conclui-se que para juvenil de tilápia, as dietas com 28% de proteína bruta podem diminuir a inclusão de farinha de peixe (25%), refletindo em melhores índices de desempenho produtivo e adaptações na morfologia do trato digestórios.

Published: December 2021

The objective of this study was to evaluate the post-mortem characteristics of lambs fed diets containing alternative foods. Twenty lambs, castrated Dorper x Santa Inês males, aged approximately 90 days and with mean weight of 20 kg were used. Experimental diets were composed of ground corn, soybean meal, mineral supplement, urea and Tifton-85 hay (forage). In addition to these ingredients, cottonseed, sunflower meal and castor bean cake were used as alternative foods in the proportions of 10, 8 and 8% of %DM, respectively. The experiment lasted 106 days, with 14 days for adaptation and 92 days for evaluation and data collection. At the end of the confinement period, the lambs were slaughtered, and the carcasses kept under cooling for a period of 24 hours. The measurements of pH, carcass temperature (internal and external) were measured in the Longissimus lumborum muscle, as well as the temperature and relative humidity of the cold chamber were measured. Muscle pH was altered as a function of diet and reached a value of 5.78 (lower pH) when lambs received the diet with castor bean cake. The internal carcass temperature was higher in the lambs that received the diet containing cottonseed (19.98°C), sunflower meal (19.71°C) and castor bean cake (19.87°C). The alternative foods can be used as ingredients in the formulation of diets for Dorper x Santa Inês lamb, for promoting the proper development of the post-mortem process, characteristic of good quality sheep meat.

Objetivou-se avaliar o alívio da dor em 20 cães com displasia coxofemoral após tenectomia pectínea, tenotomia do músculo iliopsoas, desnervação crânio lateral e ventral no antímero esquerdo, comparando com a realização da desnervação crânio lateral no direito. Foi avaliada a musculatura, andadura e testes específicos como testes de abdução e rotação ou extensão e do iliopsoas. A redução da claudicação e ganho de massa muscular foi significante no retorno de 60 dias nos dois grupos. Nos cães jovens a diferença do ganho de massa nos membros esquerdo (3,79 cm) e direito (3,6 cm) foi insignificante. Nos adultos houve diferença no ganho de massa, 0,55 cm e 1,13 cm respectivamente. Nos testes específicos das articulações ocorreu redução da dor significante nas duas articulações já a partir do retorno de 7 dias, diminuindo de forma gradativa até os 60 dias quando a diferença entre o esquerdo (1,61) e direito (1,55) foi insignificante, mostrando que a realização somente da desnervação crânio lateral é o suficiente para promover alívio da dor em cães com displasia coxofemoral.

O primeiro cão, sem raça definida, três anos de idade, foi diagnosticado com diabetes insipidus central completo, no qual há deficiência total de vasopressina confirmado no teste de privação hídrica modificado. O segundo cão, Yorkshire Terrier, sete anos de idade apresentou diabetes insipidus central parcial e o teste confirmatório utilizado foi o terapêutico com desmopressina. Ambos os testes confirmatórios só foram realizados após avaliação clínica detalhada e a exclusão das causas mais frequentes de poliúria e polidipsia. Apesar de ser uma doença incomum em cães, o diabetes insipidus deve fazer parte do diagnóstico diferencial de doenças que cursam com poliúria e polidipsia, especialmente na presença de hipostenúria.

Os objetivos da pesquisa foram avaliar as características físico-químicas, o perfil microbiano e determinar a sensibilidade aos antibióticos de enterobactérias isoladas de amostras de leite de transição bovino in natura (D0) e fermentado por 21 (D21), 30 (D30), 60 (D60), 90 (D90), 120 (D120) e 180 (D180) dias, coletadas de dez vacas leiteiras. As variáveis físico-químicas estudadas foram pH, temperatura, porcentagem de sólidos totais (ST) e densidade. Foram realizadas diluições seriadas e inoculações das amostras em meios de cultura enriquecidos e seletivos. Após a quantificação, procederam-se os testes morfotintorial, bioquímico e de antibiograma. Os resultados de pH variaram de 6,0 (D0) à 4,0 (D120 e D180). A temperatura oscilou de 21,30 a 23,33?C e a densidade no D0 foi de 1,031 g.mL-1. Em relação a (%)ST, o D0 destacou-se (13,79%) e os demais tempos de fermentação não diferiram entre si (p>0,05). No D60 nenhum crescimento de enterobactérias foi identificado, enquanto as bactérias ácido-láticas (BAL) aumentaram significativamente até o D90. Bactérias multirresistentes foram encontradas até o D30 e 29% das bactérias no D0 apresentaram índice de resistência múltipla aos antimicrobianos ?0,3. Conclui-se que a fermentação do leite de transição resulta em redução do pH, não influencia na temperatura e na densidade e mostra redução na (%) ST apenas com 21 dias de fermentação. As BAL mantêm-se viáveis até os 90 dias e os patógenos reduziram durante o período de 180 dias. As bactérias multirresistentes são eliminadas com o processo fermentativo e, de maneira geral, as enterobactérias são sensíveis aos antibióticos.

A otite externa é um dos problemas mais frequentes dentro da dermatologia veterinária. Os produtos comerciais comumente utilizados apresentam antimicrobianos nas formulações, que podem induzir resistência bacteriana em casos crônicos ou recidivantes. Desta forma, os produtos otológicos compostos por extratos vegetais tornam-se uma alternativa viável e com menos efeitos deletérios. O objetivo deste trabalho foi avaliar o potencial terapêutico de duas formas farmacêuticas a base de extratos vegetais das plantas urucum (Bixa orellana) e trigo (Triticum aestivum) no tratamento da otite externa canina. Extratos oleosos de urucum e trigo foram usados na formulação do composto LCFO 1001 e extratos etanólicos das mesmas plantas foram usados para o composto LCFO 1002. Foram utilizados 44 cães com sinais clínicos de otite externa, os quais foram avaliados por otoscopia e citologia. Os cães foram divididos aleatoriamente em 3 grupos LCFO 1001 (n=16), LCFO 1002 (n=14) e grupo controle (n=14) sendo tratados uma vez ao dia durante 10 dias e reavaliados nos dias 3, 5, 7 e 10. Foi estabelecido um score de 0 a 3 de acordo com cada sinal clínico. Após 10 dias de tratamento houve redução dos sinais clínicos em todos os grupos, observou-se a equivalência dos compostos LCF0 1001 e LCFO 1002 com um produto ceruminolítico comercial. Também foi possível observar a redução no número de animais infectados por Malassezia pachydermatis e Staphylococcus pseudointermedius. Estes resultados comprovam que os compostos possuem ação na redução dos sinais clínicos da otite externa canina, assim como possuem ação antimicrobiana.
DISCRIMINATION OF MIGRANTS IN THE HOUSING RENTAL MARKET IN THE BORDER CITIES OF THE SOUTH OF RUSSIA
Authors:   Institute for Demographic Research FCTAS RAS, Alkhasov Stanislav S.
Published: December 2021

Discrimination on the basis of nationality and race is a widespread phenomenon in the Russian housing rental market. Discrimination is prohibited by law. However, there is no law enforcement practice. Against this background, landlords, realtors and internet real estate portals publish discriminatory advertisements. In Moscow the situation is most acute. Of particular interest is discrimination in the South of Russia, a complex multiethnic and multicultural border macro-region. The analysis of the advertisements showed that discrimination in the southern Russian housing rental market is currently moderate compared to the capital region: the minimum in Astrakhan (less than 1%) and the maximum in Stavropol and Novorossiysk (about 9%). The presence of discriminatory advertisements does not lead (or almost does not lead in the case of Sochi and Krasnodar) to economic costs for migrants. At the same time, the significant part of the population (74.9% according to V.I. Mukomel’s data) is inconsistent in their attitudes towards migrants of other ethnicities. This kind of instability creates the risk of exacerbation of interethnic relations in the South of Russia, in the Northern Caucasus. Countering discrimination in the rental housing market is one of possible measures to smooth out potential tensions.

The work is devoted to the study of the awareness of students about the heroes of the Great Patriotic War. The recognizability of the names of heroes has been studied in the works of sociologists. It turned out to be very low. The answer to the question is especially relevant: can today's youth remember the description of the heroic deeds of the heroes of the Great Patriotic War? The methodological basis of the study was a survey. The collection of information was carried out from February to March 2021. A questionnaire developed by the authors was used. The study involved 302 students from 4 Vladimir universities. Their age is from 17 to 25 years old. Among them there are 95 boys and 207 girls. The average age of the subjects was 19.81 years. As a result of the study, the main sources of historical knowledge of students were identified, a rating of the films they watched about the Great Patriotic War was compiled. The upper estimates for the share of Vladimir students who know about the exploits of heroes known from Russian history textbooks were established — no more than 16.9%, and the share of Vladimir students who know about the exploits of heroes whose life history is associated with the Vladimir region were established — no more than 1.0 %. An estimate of the proportion of students who know about the combat path of their relatives — participants in the Great Patriotic War was obtained — 21.5%. The share of students who know nothing about such relatives is 53.3%. Of these, 29.1% believe that they have no such relatives. Measures to raise awareness of students about the heroes and participants of the Great Patriotic War were proposed by the authors.

The article discusses the theoretical and practical aspects of the migration policy of the Russian Federation in the context of the demographic crisis in 2021-2025, in the coordinates of the implementation of the activities of the plan for the second period of stage III of the Concept of the demographic policy of the Russian Federation until 2025, approved by the Order of September 16, 2021 No. 2580-r .2 The features of the demographic development of individual subjects of the Russian Federation in 2020 are discussed. The article deals with the issues of the methodology for analyzing migration processes as complex simultaneously social, economic, and demographic processes with the smallest inertial lag. The issue of legitimacy in these extraordinary objective and subjective conditions — raised in September 2021, is brought up for discussion. By the President of the Russian Federation V.V. Putin, the task of reaching positive dynamics of the population already by the end of 2024, the choice of priority constituent entities of the Russian Federation, in order to activate in the conditions of the demographic crisis, at the regional level, the peculiar "points of growth" and specific situational measures of migration policy in the Russian Federation are not at the federal level, but at the level of individual constituent entities of the Russian Federation. Especially those who, in the emergency sanitary and epidemiological conditions of 2020, despite the pandemic, came with a positive contribution of migration to their demographic development. The proposal of S.V. Ryazantsev on the priorities of migration policy for the countries of Central Asia is being considered.

Authors: Zhang Yuming , Xue Fei
Published: December 2021

Objective: To evaluate the effect of CBL (case-based learning) combined with case analysis in the teaching of clinical anesthesia. Methods: From June 2018 to June 2020, a total of 100 clinical anesthesia interns in Shaanxi Provincial People’s Hospital were selected as the research subjects. They were divided into two groups, the reference group (50 interns) and the study group (50 interns), by random sampling method. The reference group was under the traditional teaching method, whereas for the study group, CBL combined with case analysis was implemented. The teaching satisfaction and achievement of the interns in both the groups were evaluated. Results: The teaching satisfaction of the study group was 98%, which was significantly higher than that of the reference group (86%) (P < 0.05); before teaching, there was no significant difference in the theoretical and clinical practice scores between the two groups (P > 0.05); however, after teaching, the theoretical and clinical practice scores of the two groups increased significantly, in which the change of the research group was significantly greater than that of the reference group (P < 0.05). Conclusion: The application of CBL combined with case analysis in the teaching of clinical anesthesia has an ideal effect, improving the teaching satisfaction and achievement. It is a high-quality teaching method and is worthy of application.

Published: December 2021

There are several theoretical reasons to believe that overall media use might be related to attention deficit hyperactivity disorder (ADHD) or ADHD-related behaviors (i.e., attention problems, hyperactivity, and impulsivity). Although studies on media-ADHD relationship have accumulated, they have yielded inconsistent results, especially those from different countries. Therefore, it is still undisclosed whether children’s overall media use and ADHD-related behaviors are related to region and culture. A meta-analysis has been performed on three empirical studies investigating the relationship between overall media use and ADHD-related behaviors in children and adolescents from China. The results indicated significant relationship between overall media use and ADHD-related behaviors, OR = 2.597.
Sensing the Poetic Habitat – A Study of Middle School Chinese Teaching from the Perspectives of Life Aesthetics
Authors: Ma Liyao
Published: December 2021

The concept of life aesthetics reflects an individual’s cry for life and pursuit of beauty, inspiring individuals to discover their spiritual home, sense their poetic habitat, and enjoy the beauty of life flowing from their fingertips. Chinese education, viewed through the lens of life aesthetics, is founded on the natural characteristics of life, stimulating the aesthetic sense of individual life through the allure of language, and teaching students to view life through the aesthetic lens as well as from an understanding of life’s essence. Teachers and students are required to take an aesthetic view of life as theoretical guidance, based on core Chinese literacy, with textbook contents serving as carriers and classroom instruction as the position, closely connected to students’ actual lives, in order to help stimulate aesthetic experience among students, improve their aesthetic ability through aesthetic activities, and thus establish a correct view of life.
