Published: September 2023

Based on new modern data regarding the state of the fuel-containing masses (FCM) of the "Shelter", as well as taking into account the neutron incident of 1990 and the physical properties of the FCM of the "Shelter", the possibility of the occurrence and development of a self-sustaining chain nuclear fission reaction was considered in the FCM. It is shown that the drying of the FCM can lead to the occurrence of a single neutron burst with an amplitude comparable to the amplitude of neutron oscillations in 1990. It is also shown that the amplitude of the burst can be reduced if the rate of drying of the FCM is increased. The evaluations show that such a burst would have no impact on the environment.
Radioactive gaseous-aerosol releases from the WWR-M research reactor
Authors:   Institute for Nuclear Research, National Academy of Sciences of Ukraine, Kyiv, Ukraine, Lobach Yu.M. , Shevel V.M.
Published: September 2023

The radiation impact of the WWR-M research reactor is possible due to the release of radioactive substances into the environment, which are generated during both operation and decommissioning. One of the operator's responsibilities is to take measures to avoid or optimize the generation and management of radioactive waste to minimize the overall impact on the environment. Gaseous and airborne wastes are released into the environment through ventilation and air cleaning systems, which are essentials of the overall reactor design. The main method for preventing radioactive contamination spread to the environment is the combination of a well-designed ventilation system having thorough cleaning of the exhaust air. An analysis of the source terms of the gaseous-aerosol emissions, a description of the existing radiation control system and special ventilation system, and an analysis of the actual gaseous-aerosol emissions are presented. The total amount of gaseous-aerosol emissions during the planned reactor dismantling activity is estimated. The sufficiency and effectiveness of the existing system to ensure the required level of reactor safety are shown.

The study of 137Cs radioactive contamination of fruiting bodies of mushrooms was carried out in September - October 2022 in 18 sampling sites laid out in the Korosten district of Zhytomyr region in 3 of the most widespread forest site types (FST): fresh infertile pine site type (А2), fresh fairly infertile pine site type (В2) and moist fairly infertile pine site type (В3). It was found that the highest levels of 137Cs content in investigated FST were characteristic of symbiotrophic mushroom species - Сortinarius mucosus, Сortinarius caperatus, Sarcodon imbricatus, Imleria badia, Tricholoma equestre, Paxillus involutus, Hygrophorus hypothejus, and the lowest - for xylotrophes-saprotrophes such as Armillaria mellea and Tapinella atrotomentosa. When analyzed, it was shown that interspecific differences of average values of 137Cs aggregated transfer coefficient (Tag) among mushrooms in each FST varied in a wide range: they reached 1.1⋅103 times in FST-A2 - from 435 in Cortinarius mucosus to 0.4 m2⋅kg-1⋅10-3 in Armillaria mellea; 71.4 times - in FST-B2 - from 162 in Sarcodon imbricatus to 2.3 m2⋅kg-1⋅10-3 in Armillaria mellea; and 12 times - in FST-B3 - from 111 in Imleria badia to 9.2 m2⋅kg-1⋅10-3 in Leccinum scabrum. Also, it was shown that in genus Russula even in the same FST-B2 among five studied species a 24-fold change in average values of 137Cs Tag are observed - from 67 in Russula vinosa to 2.8 m2⋅kg-1⋅10-3 in Russula aeruginea. The results of ANOVA were discussed as well as the essentiality of the difference of the average values of Tag in mushroom species in different FST.
The Swedish School Meal Heritage — Memories of Food, Taste, and Commensality
Authors: Prell Hillevi , Sporre Cecilia Magnusson
Published: September 2023

In Sweden, free school lunch has been served for more than a hundred years, and it is now a democratic right of all elementary school children. The school meal has always been associated with different opinions and subject to much debate. The aim of the study is to explore school meal food and taste memories in a convenient sample of Swedish adults. A web-based survey was carried out in the summer of 2020. The 246 respondents attended school between the 1940s and the early 2000s. The material was collectively analyzed using NVivo 12 Pro (QSR International), resulting in two overarching themes. “The traditional school food heritage” theme consisted of accounts of traditional Swedish food through the ages and meanings attached to it. Memories were connected to likes and dislikes of certain foods and dishes. “The social school food heritage” theme consisted of accounts of coercion, control, and peer pressure, but also joy, friendship, and commensality. The Swedish school meal is a shared experience surrounded by strong feelings and memories regarding the food and the context. It means a lot both culturally and socially, acting as a carrier of a common food heritage.

Authors:   Hong Kong Metropolitan University, Hong Kong, Chan Kwok Ho , Ng Michael Chi Man ,   Richmond American University London, UK
Published: September 2023

Hong Kong is facing a serious ageing issue. Apart from that, Hong Kong is facing a shrinking labor force as the number of people in the labor force has been falling since 2018. The ageing population and shrinking labor force have stimulated the discussion on the age threshold of eligible older adults to receive retirement benefits and/or old age allowances. The impact of any policy change may depend on the health and the work capacity of the people aged around 65. Nonetheless, research on the work capacity of older adults in Hong Kong is lacking. In this study, we attempted to estimate the work capacity of older adults in Hong Kong based on the mortality rate. It was found that there is substantial untapped work capacity of older adults in Hong Kong, with a potential gain in work capacity of 3.898 years. The results of this study shed light on the making of old-age policies. With the rapid ageing population and shrinking labor force in Hong Kong, it is timely to explore if the society could further utilize the work capacity of older adults. More research on the work capacity and health of the elderly is needed.

In this paper, we aim to analyze some of the most recent measures taken at the level of the European Union for the protection of migrants. More specifically, we intend to reveal and analyze the new EU legal provisions regarding the conditions for obtaining the Blue Card and how these provisions were integrated into Romanian legislation. In order to achieve this goal, we first describe and analyze the general legal frame and the content of the prior provisions on this matter. We also examine if, during these reforms regarding the Blue Card, the process of integration is actually facilitated and how the national provisions of the Member States influence the obtaining of the mentioned document, which represents a legal form to get the right to live and work on a territory with all the rightful benefits. To provide material and moral support for the refugees, legal measures are constantly being taken at the Union level. In conclusion, we consider that even though the EU authorities are constantly trying to adjust the migrant labor legislation in order for it to be more permissive and efficient, the Union is still far from being inclusive enough. On the other hand, Romanian legislation also continuously adapts to new provisions, but the situation differs from those of other EU countries.

The involvement of parents in the lives of children is of paramount importance. Parents’ responsibility of ensuring the wellbeing of children should be taken into cognisance. Of late, some parents find themselves parenting from a distance as they leave in pursuit of employment. As a result, these parents experienced different challenges. The problem is that most researchers tend to focus on challenges experienced by children and leave out those experienced by parents. Hence, this paper aimed at synthesizing existing literature on the psychological challenges of distant parenting on mothers. In doing so, the researchers used a scoping review. The documents, which were used in the study, were purposively sampled from ScienceDirect and Google Scholar. From the literature, the researchers found that parents experienced stress and guilt as a result of leaving their children behind. Some of the parents experienced loss of connection with their children due to the distance and were stigmatized in the community/societies. It can be concluded that long-distance parenting remains high with severe implications for the lives of parents. The researchers recommend a phenomenological study on the lived experiences of fathers providing care to their distant children.
Quality Expectation Factors Influencing E-customer Satisfaction: Evidence from Online Shopping in South Africa
Authors:   Nelson Mandela University, South Africa, Shumba Tariro , Ferreira Danie ,   Nelson Mandela University, South Africa
Published: September 2023

The Covid-19 pandemic brought about an increased need for online shopping, and a steady increase in online shopping was recorded. However, only about 1.4% of online traffic eventually buys online, which leads to a need to gain knowledge of the factors which drive online shopping customer satisfaction and purchasing intention. It is imperative to consider consumer quality expectations when evaluating e-consumer satisfaction. The aim of this study establishes which quality expectation variables influence e-customer satisfaction in South Africa. The study models three quality expectation variables and e-customer satisfaction. The study uses non-probability samples of 237 respondents. A quantitative approach is used in which structured data is gathered and quantitatively analyzed. The measuring instrument used is an online survey. The items in the questionnaire are validated by conducting Exploratory Factor Analysis and subsequently Cronbach’s alpha values are calculated for each of the valid constructs to confirm inter-item reliability. Multiple Regression tests are used to determine the relationship between the independent and dependent variables. The results indicate that of the three quality expectation factors, only shopping experience expectations have a significant influence on e-customer satisfaction. Service convenience expectations and product offerings expectations are recording insignificant associations with e-customer satisfaction. The study is therefore identifying the need for online shops to augment e-customer satisfaction through exceeding customers’ quality shopping experience expectations.
Lärares förståelse av engagemang i hybrid-, fjärr, och distansundervisning
Authors: Bergdahl Nina
Published: September 2023

Engagemang och motivation är distinkta fenomen, men ändå ofta begrepp som används överlappande eller synonymt. Trots att lärares uppfattning av elevers engagemang influerar både hur lärare interagerar med eleverna och elevers betyg, har vi lite kunskap om hur lärare förstår och ser på elevers engagemang, i synnerhet när lärande sker online. Denna studie undersöker genom mixade metoder lärares initiala och fördjupade förståelse av elevers engagemang och disengagemang i digitala lärmiljöer. Tolv lärare, som regelbundet bedriver hybrid-, fjärr- eller distansundervisning i grund-, gymnasieskola eller vuxenutbildning, intervjuades två gånger och ombads att fylla i en dagbok kring elevers engagemang mellan intervjuerna. Resultaten visar att majoriteten av lärarna gradvis ökade sin användning av ordet engagemang medan användningen av ordet motivation minskade. Resultaten speglar en övergång från en vag och generell förståelse för engagemang till en mer specifikt och situationsbunden. Det visade sig att lärare ofta försöker påverka elevernas engagemang via motivation, men att insikter i motivation inte kan stödja hur lärare designar engagerande lärande aktiviteter. Sammanfattningsvis är ett professionellt språk en förutsättning för kollegial dialog, vilken behövs för att nå en ökad förståelse kring elevers faktiska engagemang i, eller disengagemang från, lärande, så att dessa insikter kan informera utvecklingen av lektionsdesign och den egna praktiken.
Impact of Individual Characteristics on Employment, Entrepreneurship and Self-Employment in Russia
Authors:   University of Tyumen, Merzlyakova Anastasia , Antosik Lyubov ,   University of Tyumen
Published: September 2023

Self-employment and entrepreneurship can be considered as mechanisms for adapting the labor market to external shocks. The purpose of this study is to identify socio-demographic and professional characteristics that determine the choice of individuals between employment, entrepreneurship, and self-employment. We used the database of microdata from workforce sample surveys at Rosstat from 2017 to 2020. The study showed significant gender, age, and professional differences in the profiles of entrepreneurs, self-employed, and employees. Employment is facilitated by the availability of vocational education and the age limit of 50 years. Self-employment is more often chosen by individuals with a low level of education and predominantly in young (15–19 years old) and older age groups. Entrepreneurs are characterized by a higher level of education and family status. The results of the logit analysis suggest that age and living in rural areas have a negative effect on employment. The sectoral structure of the region’s economy also influences the choice of labor market strategy. Due to the significant differences in age, level of education, and types of activity, we believe that self-employment is considered by individuals not as one of the stages of entrepreneurship but rather as an alternative to employment, especially for young people aged 15–19 and for the older generation (55+).
Prospects and Problems of Russian-Chinese Cooperation on the Transition to a Low-Carbon Energy Sector in the Context of Russian Strategic Planning Documents
Authors:   Russian Presidental Academy of National Economy and Public Administration, Xueqing Chen
Published: September 2023

Influenced by the changing global energy landscape and low-carbon transition, Russia is changing its energy development model from “commodity-based” to “innovative,” making supplying hydrogen and Arctic oil and gas exports an important part of its low-carbon transition in order to maintain a leading position in energy trade. The article attempts to analyze the prerequisites, advantages, and challenges faced by Russia in the low-carbon energy transition, as well as the current situation, prospects, and challenges of Russian-Chinese cooperation in the energy transition, in order to develop proposals for energy cooperation between the two countries. It is assumed that with the opening of Arctic sea routes, the Asia-Pacific region, represented by China, will become an important target region for Russian oil and gas exports. Energy cooperation is an important link in the strategic cooperation between China and Russia. There is considerable complementarity between Russia and China with regard to the transition to low-carbon energy and the development of clean energy sources. But with the international concept of low-carbon development improving, China-Russia energy cooperation faces a number of challenges, and the traditional energy industry chain and supply chain are experiencing great impacts. The two countries need to strengthen cooperation on green and low-carbon energy transformation based on carbon reduction and energy efficiency, jointly develop crossborder carbon regulation mechanisms, and actively promote global energy management.

Authors:   Volgograd State University, Petrova Elena , Voynov Nikita ,   Volgograd State University
Published: September 2023

The article discusses the main problems with the development of the IT industry in the national economy of Russia, with special attention paid to IT startups as the most risky business projects. A startup is a company with a short history of operating activities, usually based on an innovative or existing product, and therefore belongs to high-risk entrepreneurship. The IT industry of the Russian Federation was analyzed, including during the period of imposition of sanctions by foreign countries, in terms of such indicators as the volume of the industry, the costs of the corporate sector, and the population on IT technologies. A comparative analysis of the dynamics of such indicators as turnover, investments in fixed capital, and financial results in the IT sector and in the Russian economy as a whole was carried out. Both positive and negative trends in the development of the IT technology market and the development of small businesses in this sector are highlighted. The article highlights the typification and classification of startups, considers the problems of Russian IT startups, and suggests directions for their development. To implement a differentiated approach to stimulating the development of IT startups, a methodology for their classification is proposed. Testing of the methodology was carried out on the economy of the Volgograd region: the subjects of small and medium-sized businesses in the Volgograd region were analyzed, and the subjects that were potentially IT startups were identified.

Russia’s forest resources are the country’s natural wealth, which is also in demand beyond its borders. Forest resources are one of the stable sources of revenue for budgets at all levels. At the same time, the realities of modern economic truth and natural and man-made factors constantly make adjustments to the cost and volume parameters and to the very base of potential revenues. The existing mechanism for implementing the powers of administration of forestry revenues does not respond quickly enough to changing circumstances; it is scattered across the regions and poorly integrated into the modern digital system. This requires the development and implementation of new management tools, methods, and approaches, including those implemented as part of public policy, aimed at ensuring the integrated use of forest resources and increasing the level of trust of forest users in the state authorities. The article groups the main problems of applying the revenue accounting mechanism in the industry, proposes options for their solution and directions for improvement, notes the importance of information support for revenue administration, solving problems on automation of procedures for administration of payments from forest use based on the consolidation of efforts of the scientific community and direct implementers represented by public authorities.

Published: September 2023

The development of the Internet space and the transition of a part of business operations to the online mode served as the starting point for the global process of digitalization of society in general and the economy in particular, which soon enough began to affect the business models used since business management processes required transformation and optimization. This is also true for catering establishments. In the context of the rapid development of IT technologies and the widespread introduction of innovative approaches to business management processes, such as Big Data and Machine Learning, the catering industry also did not stand aside and began to actively use the opportunities provided by these tools. As a result, new service formats began to appear in the restaurant business, such as “reserving a table on the website”, “reserving a table online”, etc. Thus, it became necessary to study the degree of transformation of business models in this area. The purpose of the study is to identify the features and degree of transformation of traditional business models of public catering enterprises in the context of digitalization. The research methods are comparative analysis, statistical analysis, benchmarking, classification, and ranking. The authors conclude that modern Russian public catering enterprises are striving to switch to a digital business model since its advantages are quite obvious.

Based on empirical materials on the investment practice of the Russian financial market, the article examines the economic interests of participants in operations with digital financial assets as well as the risks to which they are exposed in these investment relations. The authors identify coinciding and immanent to each of the participants in the operations target intentions that the participants are interested in implementing. The participants are the Bank of Russia, the investor, the operator of the information system in which the issue of digital financial assets is carried out, the recipient of the investment, and the bank of the operator of the information system. The risks specific to each of these participants are disclosed and analyzed, and the authors substantiate proposals for the prevention and relief of the identified risks likely when conducting operations and digital financial assets. The dynamics of the admission of information system operators and operators of the exchange of digital financial assets to the financial market are being studied, and the composition and volume of their operations for the issuance of digital financial assets for the period 2022–2023 are being critically assessed. The dynamics of the number of recipients of investments (persons issuing digital financial assets and the total volume of attracting resources from investors through the issuance of digital financial assets) are investigated. The dynamics of the growth of the number of individual investors in the Russian financial market are considered using the example of their client accounts with positions on securities; proposals are made on the need to adopt a targeted federal program to train citizens in behavior in the field of Internet investment. A methodological matrix of interests-risksmeasures has been formed for participants in operations with digital financial assets, which provides for the allocation of overlapping and immanent interests-risks-measures and discloses mandatory preventive measures. Which should be applied by each of the participants in operations with digital financial assets to ensure timely and full execution of settlements between them and stable turnover of digital financial assets in the investment segment of the Russian financial market.

Methods of molecular dynamics and DFT calculations have been used to study the reduction mechanisms of UO2 as the most representative part of spent nuclear fuel to metallic uranium. It is shown that the critical softening of the combined modulus of elasticity C11-C12 to zero is the reason for the destruction of the UO2 crystal as a result of the removal of oxygen from it. This destruction is accompanied by an order-disorder phase transition in the oxygen subsystem of the crystal under consideration. DFT calculations indicate a continuous decrease in the band gap as oxygen is removed from the UO2 crystal. When the system reaches the composition U2O3, the band gap disappears and the system becomes electrically conductive. The appearance of the dielectric-conductor transition explains the realization of the FFC Cambridge process during the recovery of spent nuclear fuel. The passage of Li+ and Cl– ions of the LiCl melt through cylindrical channels in a UO2 crystal with cross-sectional radii from 0.25 up to 2 nm has been studied. The strength of the external electric field required for the passage of these channels decreases with an increase in the channel cross section, and the number of Cl– ions entering the channel increases. On the walls of the channels that pass ions with charges of both signs, colonies of adsorbed Cl– and Li+ atoms appear separated from each other, between which strong electric fields are formed. The existence of such fields can cause Li+ ions to move deep into the material being reduced.
The Effect of Distance Education on Lifelong Learning
Authors: ŞAHİN KÖLEMEN Cansu
Published: September 2023

Today's technological developments are effective in all areas of social life. One of the fields where technological developments are involved is education. With the inclusion of information and communication technologies in education and training processes, one of the concepts discussed is distance education. Since the learning process with distance education is independent of time and space, it has given birth to the concept of lifelong learning. Lifelong learning is expressed as the realization of learning wherever the individual is without any restrictions. The most important point that lifelong learning affects is equality of opportunity in education. Because lifelong learning puts the individual in the center. Therefore, by changing the role of the school, it gives importance to out-of-school learning. Thus, it supports the personal development of the learner. However, it provides benefits to society in terms of economic growth. It also emphasizes that education should not be subject to a certain time interval. Considering the advantages it provides, this skill should be included in the education system. Based on the reasons stated, in this study, the effect of distance education students on the lifelong learning tendency was examined. Quantitative research method was preferred in the study. Quasi-experimental research, which is one of the quantitative research methods, was used. Convenience sampling method was used in the research. A total of 251 participants were reached for this study with the convenient sampling method. The "Lifelong Learning Tendency" scale, which was developed in 2015, was used as a data collection tool in the research. In the analysis of the data, the independent t-test (unpaired t-test) was used to determine the differences in the pre-test and post-test scores between the groups. In line with the findings obtained as a result of the research, it was determined that the group who received education with distance education had a higher tendency to lifelong learning than the group who did not receive education with distance education. Suggestions were made in line with the results obtained.

In this study, which aims to examine all of the articles and theses in the field of education in Turkey on the basis of the concepts of sustainability, environmental sustainability and sustainable development, and to address sustainability in all its dimensions, the data were analyzed by meta-synthesis (thematic content analysis). Within the scope of the research, 232 study and education subject areas accessed from the Turkish Higher Education Institution National Thesis Center and DergiPark databases were discussed in the context of the key concepts of "sustainability, sustainability, sustainable development, sustainable environment, environmental sustainability". In the data analysis process, the subject of the research, its method, data collection tools, sample, data analysis, results and suggestions were examined. In most of the studies examined, it is aimed to measure attitudes, perception, awareness and competence towards sustainability and it is seen that the most quantitative method is preferred. While the most educators are selected as the sample group, the size of the study group is between 301 and 1000. Likert-type questionnaires were used in quantitative research and semi-structured interviews were used in qualitative research. While inferential analyzes were preferred the most from quantitative analyzes, content analysis was preferred from qualitative analyzes. It has been observed that there are many studies that increase belief, attitude, perception, awareness, value and tendency in studies where trainings are given within the scope of sustainability. It is seen that there are themes such as curriculum review, scale development and institution review. Recommendations are grouped and presented to researchers, educators, politicians and parents. Based on these results, it can be said that the studies are trying to measure the awareness and awareness of educators and prospective educators about sustainability and to reveal to what extent they can transfer this to future generations.

ABSTRACT Objective The aim of this study was to compare the Global Leadership Initiative on Malnutrition and Subjective Global Assessment methods produced by the patient in the nutritional assessment of cancer in-patients. Methods Cross-sectional study with a prospective variable, conducted with patients admitted to a public hospital in Pernambuco, Brazil. The application of these tools and the diagnosis of malnutrition were performed within the first 48 hours of admission. Sociodemographic, clinical and laboratory data were obtained from the medical records and weight, height, arm circumference, triceps skinfold and handgrip strength data were collected. Results The 82 patients evaluated included mostly men aged ≥ 60 years with less than 8 years education. Malnutrition frequency was 93.7% according to the Subjective Global Assessment and including 23.2% severe malnutrition while, according to the Global Leadership Initiative on Malnutrition, 50% of the patients were considered severely malnourished. Malnutrition by the Global Leadership Initiative on Malnutrition showed a sensitivity of 82.9% and when associated with handgrip strength sensitivity was 90.8%, considering the Subjective global assessment produced by the patient as a reference; on the other hand, the specificity was 16.7% independently of adding handgrip strength. None of the anthropometric variables was associated with the reference tool. Conclusion The Global Leadership Initiative on Malnutrition proved to be a very sensitive tool for diagnosing malnutrition when compared to the gold standard, particularly for severe malnutrition, but with little specificity. The need for a comprehensive nutritional assessment in the clinical practice was confirmed, using the parameters available and not interpreting them separately.

Abstract This study aimed to investigate the effect of growth and differentiation factor 9 (GDF-9) during the in vitro culture of isolated caprine early antral follicles. The isolated and selected early antral follicles were individually cultured for 18 days, and the following treatments were tested: α-MEM+ (control treatment) or α-MEM+ supplemented with 200 ng/mL GDF-9. The following endpoints were evaluated: follicular growth and morphology, estradiol production, oocyte nuclear maturation, and relative expression of key genes related to steroidogenesis (CYP19A1, CYP17, and insulin receptor) and basement membrane remodeling (MMP-9 and TIMP-2). In both treatments, a decrease was observed in the percentage of morphologically intact follicles with a concomitant increase in the rates of extruded and degenerated follicles (P < 0.05). The GDF-9 treatment showed higher rates of extruded follicles only on day 6 of culture (P < 0.05). Follicle diameter increased progressively throughout the culture period (P < 0.05) with similar diameters between treatments at all culture times (P > 0.05). Growth and differentiation factor 9 increased the daily growth rate from the first to the second third of culture, with higher values (P < 0.05) than control in the second third. Oocyte maturation rate as well as estradiol levels and relative mRNA expression for CYP19A1, CYP17, MMP-9, TIMP-2, and insulin receptor genes were similar between treatments (P > 0.05). This study shows for the first time that GDF-9 added to a culture medium increased the follicle growth rate of goat early antral follicles cultured in vitro.

Abstract An estrous-detection patch was used to determine the optimum timing for STAI and the necessity of GnRH at STAI on a 7-day CO-Synch+CIDR protocol. Crossbred beef cows (n=216) were stratified into the following treatment groups: CTRL=TAI (n=67) at 72 h post CIDR removal, or TRT=STAI (n=149) at 72 or 84 h post CIDR removal. All females received GnRH (100 mcg) plus a CIDR on d0, PGF2α, CIDR removal, and an Estrotect estrous-detector patch on d7. At 72 h post-CIDR removal, a patch score was assigned (PS1<50% removed; PS2>50% removed) to all females. Cows in the CTRL group were administered a second GnRH (100 mcg) at 72 h TAI. Cows in the TRT group with PS2 were not administered GnRH. At 84 h, the remaining TRT group cows were given a second PS; cows with PS1 received a GnRH (100 mcg), and cows with PS2 were not administered. Results: The TAI pregnancy rates were similar (P=0.81) between the CTRL (45.6%) and TRT (44.8%) groups. Pregnancy rates tended to be higher (P=0.07) for cows with PS2 (50.3%) than for those with PS1 (29.4%). However, by extending TAI to 84 h in unresponsive cows, 82.0% of TRT cows did not receive a second injection of GnRH at TAI. It was concluded that the estrous detector patches reduced the percentage of cows that required GnRH at TAI without compromising pregnancy rates. The estrous detector patches significantly reduced the number of cows that received a second GnRH injection at TAI.

ABSTRACT Objective: To analyze how the healthcare of black immigrants was conducted during the COVID-19 pandemic in Primary Healthcare. Method: An exploratory-descriptive study with a qualitative approach, carried out through semi-structured interviews with professionals who worked in 10 Health Units in the city of Curitiba, Brazil, from October 2020 to January 2021. Structural racism was the conceptual framework. The statements were submitted to content analysis after using the MAXQDA program as support. Results: A total of 21 professionals from the multidisciplinary team participated and three categories emerged from the analyzes: Healthcare for black immigrants in PHC during the Covid-19 pandemic; Limits and potentialities of PHC for healthcare for black immigrants; Structural racism in PHC practices aimed at black immigrants. Conclusion: Action in the pandemic was guided by protocols that did not expand healthcare to vulnerable populations, including black immigrants. The main barrier was communication, as most black immigrants in the surveyed locations were Haitians. Structural racism was identified in professional practice.

RESUMO Objetivo: Descrever sobre a utilização da escala de Fugulin para classificação de pacientes pediátricos internados em uma unidade respiratória como subsídio para a alocação de recursos humanos, diante do aumento de casos de Síndrome Respiratória Aguda Grave. Método: Relato de experiência com coleta de dados em prontuário, realizado em um hospital infantil da região metropolitana de Curitiba, aprovado pela Instituição e pelo Comitê de Ética em Pesquisa com Seres Humanos. Resultados: Entre fevereiro a maio de 2022, a porcentagem dos pacientes categorizados em cuidados mínimos e intermediários decaiu em 53 e 11,4%, respectivamente, ao passo que os de cuidados de alta dependência e semi-intensivos expandiram 31,2 e 84,2%. Além disso, em apenas quatro meses, houve aumento considerável na positividade das virologias em comparação aos doze meses de 2021. A suscetibilidade das crianças ao desenvolvimento de infecção respiratória grave foi comprovada através da diminuição de virologias com resultados não detectáveis. Conclusão: Os resultados obtidos permitiram concluir que houve um aumento expressivo da complexidade dos pacientes admitidos na unidade respiratória, sendo essencial o provimento de equipe de enfermagem compatível com as necessidades de cuidados.

RESUMO Nosso objetivo é investigar como relações entre ciência e imaginação são discursivamente construídas em uma turma de crianças ao longo dos três primeiros anos do ensino fundamental. Com base na Etnografia em Educação, articulada à Educação em Ciências, analisamos eventos que evidenciam como referências ao contexto não escolar contribuem para o ensino de ciências de forma articulada à imaginação/atividade criadora. Os resultados demostram a ocorrência de: uma perspectiva de ciências prioritariamente voltada para resultados/produtos da ciência e outra focalizada em procedimentos/processos de construção de conhecimento/práticas; uma forma de atividade criadora relacionada à interação com materiais para investigar fenômenos e outra principalmente ligada à criação de narrativas imaginárias; e maior participação e potencialização da atividade criadora quando se fala sobre o espaço da casa no espaço escolar.
Science and imagination in elementary school

ABSTRACT Our objective is to investigate how relationships between science and imagination are discursively constructed within a group of children in the first three years of elementary school. Based on Ethnography in Education, articulated with Science Education, we analyze events that demonstrate how references to the non-school context contribute to the teaching of science in a way articulated with imagination/creation activity. The results demonstrate the occurrence of: a science perspective primarily focused on results/products of science and another focused on procedures/processes of knowledge construction/practices; a form of creation activity related to the interaction with materials to investigate phenomena and another mainly related to the creation of imaginary narratives; and greater participation and enhancement of creation activity when talking about the space of the house in the school space.
