Authors: Martín Carrasquilla Olga , Muñoz San Roque Isabel , Santaolalla Pascual Elsa 
Published: May 2023

Este artículo describe el proceso de construcción y desarrollo de la escala ACESTEM para medir las actitudes hacia la ciencia en la Educación STEM en estudiantes de edades entre los 10 y 14 años. Después de realizar la validez de contenido por juicio de expertos, se procedió al análisis factorial exploratorio (AFE) de la escala en una muestra de 408 estudiantes (210 chicas y 198 chicos) que ofreció una estructura de cuatro factores (Gusto por la ciencia, Interés profesional por la ciencia, Autoeficacia y Utilidad percibida de la ciencia) con 24 ítems y un Omega de McDonald con una fiabilidad de 0.909. El posterior análisis confirmatorio (AFC) realizado en una muestra diferente de 295 estudiantes (114 chicas y 181 chicos) confirmó la estructura de cuatro factores, obteniendo unos índices de ajuste satisfactorios con un Omega de McDonald de 0.917, quedando una escala de 21 ítems. El análisis de los resultados permite constatar una disminución del interés del alumnado por la ciencia a medida que avanza la edad, así como la influencia de la madre con profesión STEM sobre la autoeficacia, especialmente en las alumnas. La escala ACESTEM puede ayudar al profesorado y al equipo de orientación educativa a determinar las creencias de los estudiantes que afectan a las decisiones relevantes sobre la elección de posibles itinerarios relacionados con la Educación STEM, así como a promover acciones que impactarían positivamente en la calidad de la enseñanza para conseguir una Educación STEM para todos.
The concept of cultural sovereignty in the structure of the Foundations of State Cultural Policy
Authors: Pilyak Sergey Aleksandrovich 
Published: May 2023

Cultural heritage, which serves as a substratum of national identity, forms the right of the state to its own sovereignty. The substantiated proof of the possibility of independence from other cultures and nations has relatively recently entered the conceptual field of the philosophy of culture. In January 2023, significant changes made to the Foundations of the state Cultural Policy took into account the concept of cultural sovereignty and, to the necessary extent, justified its high importance for the development of the state and society. The fundamental role of culture in the creation and development of the state has been repeatedly recognized as one of the priorities. It should be noted that even later this priority was not a Russian regulatory novel. The purpose of the study is to consider a range of concepts and legal novels reflecting the sphere of cultural heritage. The long-term work of an extensive circle of philosophers and culturologists has been crowned with the recognition of the value of culture in the system of state regulation of various spheres of human activity. As a result of the research, the conclusion is made about the relevance and timeliness of the implementation of the most important philosophical concepts in strategic planning documents and the high potential practical significance of the actualization of cultural heritage in order to achieve the results of the state cultural policy. In conclusion, it is noted that heritage as a cultural phenomenon has direct access to its semantic and value core. The preservation of cultural identity through the consistent building of cultural sovereignty is one of the most important priorities of modern state policy.

Published: May 2023

The reliability of building structures is a very important design criterion. The required level of security depends not only on the function and purpose of the facility, but also on the parameters considered at the design stage. There are factors to that with some probability they increase the uncertainty of the adopted parameters in the calculations, as a result of which the structure fails. It happens that execution errors are made during the process of creating an object. One of the significant disadvantages is the increase in the reinforcement cover thickness compared to the designed value, and hence the reduction of the effective depth of cross-section. The purpose of the analyzes presented in the article was to estimate the influence of the top reinforcement cover thickness on the reliability and bending and punching resistance in the reinforced concrete slab being part of the slab-column system. The reliability index βc was determined by the Cornell method. The analysis focused on a fragment of a cross reinforced slab, which is an element of the column-slab structure of a shopping mall. The ARSA 2019 program was used for the analysis of the structure. The impact of the coefficient of variation of the effective depth on the reliability index was also analyzed. The obtained values were compared with the target value of the reliability index read from EN 1990.

Based on the assumptions of the circular economy model and sustainable development, we are currently looking for natural and ecological materials in terms of wastewater treatment of pollutants. This article presents the research of three mineral materials – lava rock (LR), lightweight sintered aggregate (LSA) and lightweight clay aggregates (LCA) used as filling of filtration columns for the treatment of real wastewater. The filtration process was carried out under various hydraulic loads in two columns, one of which was additionally supported by the aeration process. The post-treated sewage was characterized by the following parameters: COD (chemical oxygen demand), TOC (total organic carbon), phosphate phosphorus (P-PO4), total nitrogen (TN) and total phosphorus (TP). Among the hydraulic loads applied, the most optimal loads were OhI = 0.25 m3/(m2·h). Certyd turned out to be the most effective with supporting filtration with the aeration process in removing organic compounds (reduction of 65.1% COD and 38.2% TOC at OhI). Lava rock seems to be a promising material reactive in terms of removal of biogenic compounds such as nitrogen (efficiency 23.8% at OhI) and phosphorus (64.2% reduction of TP at OhI) and organic compounds (21.4% reduction of TOC at OhI in conditions without aeration). LCA shows the best efficiency in sorption of phosphorus compounds (41.6% reduction of TP at OhI) and organic compounds (21.4% TOC reduction at OhI under non-aerated conditions).

Published: May 2023

Thermal insulation materials and technologies for thermal insulation of houses were investigated. The widespread use of such materials is due to the saving of fuel and energy resources, in particular, during the operation of buildings and structures. The subject of the analyzed stage of the research is the use of modern thermal insulation materials in construction, comparative characteristics of materials and processes associated with thermal insulation technologies.
A list in the form of a table of the most used on the Ukrainian thermal insulation materials with comparative characteristics was considered. The most optimal from the point of view of ecology are ecowool, foam glass and mineral wool. The disadvantages of materials are the high cost of work and installation. Polyurethane foam, relative to other heat-insulating materials, has a minimum thermal conductivity. Also, along with glass wool, it is an excellent sound insulating material. The main requirements for thermal insulation materials are fire resistance. All listed materials correspond to this characteristic, except for expanded polystyrene.
The construction industry in Ukraine is dependent on the country's economic factors. Back in 2015, there was a sharp decline in the market volume associated with an unstable political and economic situation. However, a year later, the pace of construction work has noticeably accelerated by 13,1%. This is due to the growth of the real estate market, the level of purchasing power, the popularization of energy-efficient construction in the country, and, therefore, the latest technologies and innovations in the direction of energy-saving materials.

Introduction: Phenylhydrazine has been used in many studies to evaluate its modulatory effects in various biochemical parameters in whole blood and red blood cell lysate. Jatropha tanjorensis Euphorbiaceae have high antioxidants properties; its leaves phytochemical analysis shows the presence of flavonoids, tanins, terpenoids, saponis. This study investigated the ameliorative effects of Jatropha tanjorensis Euphorbiaceae on phenylhydrazine induced haematological alterations in albino Wistar rats.
Materials and Methods: Wistar rats of both sexes (180-200g) were divided into 4 groups (n=5). Group 1 received rat chow; Group 2 received (200 mg/kg) of J. tanjorensis orally. Group 3 received phenylhydrazine only (10 mg/kg). Group 4 received phenylhydrazine (10 mg/kg) + J. tanjorensis (250 mg/kg). All animals were allowed free access to clean drinking water and normal rat chow ad libitum for 35 days. After which animals were sacrificed and blood samples collected for biochemical analysis.
Results: Results obtained showed that phenylhydrazine induced normochromic anemia with significant increase in white blood cell count, and neutrophil counts, eosinophils (insignificant) count with a significant reduction in lymphocyte count. However, J. tanjorensis extract reversed the adverse haematological changes induced by phenylhydrazine.
Conclusion: In conclusion, Jatropha tanjorensis Euphorbiaceae demonstrated antioxidant, anti-inflammatory, and anti-thrombotic effects and reversed the haematological alterations brought upon by phenylhydrazine administration.

The study was conducted by laboratory techniques in the department of Food Science and Nutrition, College of Community Science, Acharya Narendra Dev University of Agriculture & Technology, Kumarganj, Ayodhya, during 2020-22 secession. The study on title “Nutritional Evaluation and value addition of Drumstick Leaves” was undertaken to determine the physical and nutritional composition of immature and mature drumstick (Moringa oleifera) leaves. The proximate composition of drumstick leaves was investigated in the studies. The moisture content of fresh immature and mature leaves was found to be 73.8 and 71.6 %. Protein estimated by Lowery method, the protein content of immature leaves 22.22 and mature leaves 22.90 %. The Crude fiber content in immature leaves 2.26 and mature leaves 6.68 %. According to the proximate analysis of all nutrient it has been found that in the drumstick leaves calcium in immature leaves 1990 mg /100 g and in mature leaves 2029 mg /100 g. Phosphorus value in immature leaves 337mg/100g and in mature leaves 350 mg /100 g which is higher than other nutrients. In this series Vitamin ‘C’ content in fresh immature leaves is 216mg/100g and in mature leaves 207 mg /100 g. Fresh drumstick leaves were successfully used for preparing different nutritive food products- bhujia, paratha, saag and juice. Eating drumstick-based food products is good for those suffering from malnutrition. Moringa oleifera leaf powder should be advocated for supplementation in household diets especially in rural and urban communities. Drumstick (Moringa oleifera) is one of the promising plants which could contribute to increased intake of essential nutrients and health promoting phytochemicals. Leaves can be consumed raw, boiled, or stored as a dry powder for several months without losing their nutritious content.

Aims: This research aimed to determine the Hepatotoxicity via oral and inhalation routes using animal model and its Risk assessment when exposed to Chlorview pesticide (Chlorpyrifos 40% E.C.).
Study Design: The animals were divided into two groups for oral and inhalation routes of exposure. They were divided into 4 groups of 5 animals each for oral and 4 groups of 4 animals each for inhalation.
Place and Duration of Study: This study was conducted in the Department of Biochemistry Laboratory University of Nigeria Nsukka.
Methodology: The hepatotoxicity and risk assessment studies were carried out using a colorimetric assay and standard methods respectively.
Results: Oral exposure to Chlorview led to a significant (p<0.05) increase in the activity of AST, ALT, and ALP when compared to the control. The risk assessment studies showed oral subchronic toxicity at the dose of 15.5 mg/kg b.w when exposed to Chlorview with a bioaccumulation factor (BAF) of 2.50. The oral exposure recorded a hazard quotient (HQ) of 3.4 and a risk quotient (RQ) of 0.1, a risk presumption of acute restricted use. There was no accumulation of the pesticide or its derivative via the inhalation route rather a macroscopic deposition of fat on the liver identified as cholesterol was seen.
Conclusion: This research suggests that exposure to Chlorview pesticide through oral and inhalation routes can pose a reasonable risk to human health.

ImportanceThe expansion of genetic and genomic testing in health care has led to recognition that these tests provide personal as well as clinical utility to patients and families. However, available systematic reviews on this topic have not reported the demographic backgrounds of participants in studies of personal utility, leaving generalizability unclear.ObjectiveTo determine the demographic characteristics of participants in studies examining the personal utility of genetic and genomic testing in health care.Evidence ReviewFor this systematic review, we utilized and updated the results of a highly cited 2017 systematic review on the personal utility of genetics and genomics, which identified relevant articles published between January 1, 2003, and August 4, 2016. We also used the original methods to update this bibliography with literature published subsequently up to January 1, 2022. Studies were screened for eligibility by 2 independent reviewers. Eligible studies reported empirical data on the perspectives of patients, family members, and/or the general public in the US on the personal utility of any type of health-related genetic or genomic test. We utilized a standardized codebook to extract study and participant characteristics. We summarized demographic characteristics descriptively across all studies and by subgroup based on study and participant characteristics.FindingsWe included 52 studies with 13 251 eligible participants. Sex or gender was the most frequently reported demographic characteristic (48 studies [92.3%]), followed by race and ethnicity (40 studies [76.9%]), education (38 studies [73.1%]), and income (26 studies [50.0%]). Across studies, participants disproportionately were women or female (mean [SD], 70.8% [20.5%]), were White (mean [SD], 76.1% [22.0%]), had a college degree or higher (mean [SD], 64.5% [19.9%]), and reported income above the US median (mean [SD], 67.4% [19.2%]). Examination of subgroups of results by study and participant characteristics evidenced only small shifts in demographic characteristics.Conclusions and RelevanceThis systematic review examined the demographic characteristics of individual participants in studies of the personal utility of health-related genetic and genomic testing in the US. The results suggest that participants in these studies were disproportionately White, college-educated women with above-average income. Understanding the perspectives of more diverse individuals regarding the personal utility of genetic and genomic testing may inform barriers to research recruitment and uptake of clinical testing in currently underrepresented populations.

ImportanceTo our knowledge, no published studies have investigated the association of ambulatory activity with risk of death among young and middle-aged American Indian individuals. The burden of chronic disease and risk of premature death is higher among American Indian individuals than among the general US population, so better understanding of the association of ambulatory activity with risk of death is needed to inform public health messaging in tribal communities.ObjectiveTo examine the association of objectively measured ambulatory activity (ie, steps per day) with risk of death among young and middle-aged American Indian individuals.Design, Setting, and ParticipantsThe ongoing longitudinal Strong Heart Family Study (SHFS) is being conducted with participants aged 14 to 65 years in 12 rural American Indian communities in Arizona, North Dakota, South Dakota, and Oklahoma and includes up to 20 years of follow-up (February 26, 2001, to December 31, 2020). This cohort study included SHFS participants who had available pedometer data at baseline. Data analysis was performed on June 9, 2022.ExposuresObjectively measured ambulatory activity at baseline.Main Outcomes and MeasuresOutcomes of interest were total and cardiovascular-related mortality. Mixed-effects Cox proportional hazards regression was used to estimate hazard ratios for risk of death, with entry at the time of the pedometer assessment and time at risk until death or the latest adjudicated date of follow-up.ResultsA total of 2204 participants were included in this study. Their mean (SD) age was 41.0 (16.8) years; 1321 (59.9%) were female and 883 (40.1%) were male. During a mean follow-up of 17.0 years (range, 0-19.9 years), 449 deaths occurred. Compared with participants in the lowest quartile of steps per day (&amp;lt;3126 steps), individuals in the upper 3 quartiles of steps per day had lower risk of mortality, with hazard ratios of0.72 (95% CI, 0.54-0.95) for the first quartile, 0.66 (95% CI, 0.47-0.93) for the second quartile, and 0.65 (95% CI, 0.44-0.95) for the third quartile after adjustment for age, sex, study site, education, smoking status, alcohol use, diet quality, body mass index, systolic blood pressure, prevalent diabetes, prevalent cardiovascular disease, biomarker levels (fibrinogen, low-density lipoprotein cholesterol, and triglycerides), medication use (hypertensive or lipid-lowering agents), and self-reported health status. The magnitude of the hazard ratios was similar for cardiovascular mortality.Conclusions and RelevanceIn this cohort study, American Indian individuals who took at least 3126 steps/d had a lower risk of death compared with participants who accumulated fewer steps per day. These findings suggest that step counters are an inexpensive tool that offers an opportunity to encourage activity and improve long-term health outcomes.
