Published: September 2021

The study aim to identify the reality of school bullying from the perspective of the victims, bullies, educators, and workers in one of the private schools at Nablus city. The researchers employed the qualitative research method that was based on face-to-face interviews. Moreover, the age range of the selected sample was between 13-16 years old. The study's findings revealed the forms of bullying at the school, its causes, and the school policy to tackle it. Most of the results were characterized by having a problematic definition of "bullying." Moreover, the school was confused about dealing with bullying in all its forms, and there was a clear strategy to address the problem. The study recommend the necessity of school-based bullying prevention and treatment programs designed to reduce the bullying phenomenon at schools.
Effectiveness of cauda epididymal plasma-2 and lecithin based diluents to minimize abnormality of sexing albumin spermatozoa during cold storage
Authors: Firdaus Frediansyah , Ratnawati Dian
Published: September 2021

Background and Aim: Lecithin based diluent such as AndroMed, is a semen diluent made without animal components to prevent the risk of disease transmission, while glutathione (GSH) is an intracellular non-enzymatic antioxidant that prevents cell damage due to reactive oxygen species. Meanwhile, the specific impact of AndroMed and GSH combinations on spermatozoa abnormalities has not been fully studied. Therefore, this study aims to determine the effect of using cauda epididymal plasma-2 (CEP-2) and AndroMed diluents with or without the addition of GSH on the abnormalities of sexing semen of Ongole crossbred bulls in cold storage.

Materials and Methods: This study used a factorial completely randomized design 2×2, the first factor was types of diluent and the second was with or without the addition of GSH. Observation of spermatozoa abnormalities was carried out at a storage time of 0-5 days using 297 ejaculations of liquid semen, with 100 spermatozoa observed per smear of each ejaculate. Furthermore, the data were analyzed using a two-way analysis of variance and the significant threshold (p-value) for statistical analysis was set at <0.05.

Results: The results showed that there was a significant difference (p<0.05) between AndroMed and CEP-2 in minimizing the abnormalities of upper layer spermatozoa (X), with parameters DH and AD on day 0, damage of spermatozoa (DMR) on days 1-5, and dag-like defect (DLD) on day 5. Furthermore, spermatozoa abnormalities in the lower layer (Y) showed a significant difference between diluents in the parameters of AD on day 1, DMR on days 0-5, and DLD on days 1-5. The significant difference between with or without the addition of GSH in the X sperm was observed in the DH parameters on day 0 and DMR on 5, while there was no significant difference in the Y sperm.

Conclusion: Based on the results, AndroMed has the potential to minimize spermatozoa abnormalities compared to CEP-2 diluent in sexed liquid semen. Therefore, AndroMed diluents with or without the addition of 1 mM GSH have no significant effect on spermatozoa abnormalities.

La generación de mapas actualizados de uso del suelo en regiones de agricultura de regadío es importante tanto para el monitoreo productivo como para la aplicación de modelos hidrológicos o de otro tipo. Por requerimientos de costo y tiempo, las herramientas de percepción remota y Sistemas de Información Geográfica son de gran ayuda para tal fin. En este estudio se delimitaron los usos del suelo, con énfasis especial en las tierras de agricultura de riego, utilizando imágenes Landsat 8 de tres periodos con condiciones de lluvias diferentes durante 2017; para cada imagen se obtuvo el Índice de Vegetación de Diferencia Normalizada (NDVI, por sus siglas en inglés). Los NDVI se combinaron para formar una imagen Red-Green-Blue- NDVI (RGB-NDVI). Con el programa ERDAS Imagine 2014 se obtuvieron las firmas espectrales para los usos del suelo y vegetación identificadas con el programa Google Earth. Se ubicaron puntos al azar para verificar si el uso del suelo del mapa obtenido corresponde con el uso verdadero. Además, se comparó el mapa obtenido a partir de imágenes de satélite con el mapa de Uso del Suelo y Vegetación, Serie VI, considerado el mapa oficial más actualizado en México. Los mapas se evaluaron utilizando matrices de confusión e índices de confiabilidad. El mapa generado con imágenes Landsat 8 tuvo mayor confiabilidad que el de Uso del Suelo y Vegetación, Serie VI. El mapa obtenido es útil para dar seguimiento a los cambios de uso del suelo y es insumo para modelos hidrológicos, como el Soil and Water Assessment Tool (SWAT), con el fin de estimar los efectos de prácticas agrícolas sobre las corrientes superficiales.

La «esencia del cristianismo» en los comienzos
Authors: Guijarro Oporto Santiago
Published: September 2021

La presente reflexión interroga al Nuevo Testamento acerca de lo que constituye la «esencia del cristianismo». Comienza constatando la centralidad de Jesucristo, a quien sus primeros seguidores consideraban cimiento y piedra angular. A continuación, observa que las confesiones pascuales en las que se asienta esta convicción no sólo dicen algo sobre Jesús, sino que también afirman algo sobre Dios, cuya imagen queda modificada al confesar a Jesús como Hijo y Señor. Esta nueva imagen de Dios aparece así como el rasgo más distintivo del cristianismo en los orígenes.

Published: September 2021

Visceral obesity is associated with the development of several diseases, such as osteoarthritis (OA), cardiovascular disease (CVD), type 2 diabetes mellitus (DM), and breast cancer (BC). Recent years have discussed the value of the immune system in the pathogenesis of the disease, but its role remains unclear. The aim of the study was to investigate the cellular immune responses in diseases comorbid with visceral obesity (OA, CVD, type 2 DM, BC). The study included 36 patients with OA, 61 – CVD, 60 - type 2 DM, 98 - breast cancer in postmenopausal women, 30 patients with benign breast tumors. The control group involved 21 healthy people. Our study includes anthropometric, clinical, biochemical, immunological (the reaction of lymphocyte blast transformation to PHA, insulin, antigens cartilage, IGF-1) and morphological methods of investigation. Patients with obesity associated diseases have reduction of proliferative activity in response to PHA and increased frequency of autoimmune reactions to insulin suppressed by prostaglandin-synthesizing cells and/or cells with histamine receptors (144/239 vs. 2/21, p <0,001). This type of cell-mediated immunity is correlated with the anthropometric data (BMI, waist circumference, WC/height) and disorders of carbohydrate metabolism. Conclusions. Despite the differences of diseases associated with visceral obesity, the fact united them is the presence of metabolic disorders, the development of an autoimmune response to insulin, suppressed by prostaglandin synthesizing cells and/or cells with receptors to histamine (more than 60%), which suggests the involvement of the immune system in the genesis of these disorders.

Minocycline is the tetracycline antibiotic used in the therapy of different forms of acne vulgaris. It was shown previously that S. aureus may play a role of causative agent in inflammatory acne. This study was performed aiming to estimate sensitivity of staphylococcal strains from acne patients towards minocycline. Group of acne 29 patients 17-31 years old with different severity grades was compared with control group of 22 volunteers of the same age. Staphylococcal microflora was obtained from face skin use the stamp method and identified by standard scheme. Sensitivity of strains to minocycline was estimated by microdilution method in DMEM medium. In both groups 5 species of staphylococci were found: S. aureus, S. epidermidis, S. haemolyticus, S. intermedius, S. saprophyticus. At that we established that S. aureus was the main species in acne group I (62%) as well as in control group (38%). From all species studied the S. epidermidis was found to be most sensitive to minocycline with median of the minimal inhibiting concentration equaling 4 µg/ml, and most resistant was S. saprophyticus – with MIC of 16 µg/ml. Sensitivity of strains of S. aureus to minocycline was higher in acne group than in controls: 39% of acne group isolates had MIC of 4 µg/ml, although 63% of control group isolates had MIC of 8 µg/ml.

The Journal of Science Education for Students with Disabilities (JSESD)d is the premier journal focusing on the intersections of science education for students with disabilities. JSESD provides valuable content and context for teachers and researchers on what works in advancing science access, practices, and knowledge for all students across settings, grades, ages, and exceptionality. One way in which JSESD supports teachers and researchers is through publication of practitioner manuscripts also referred to as Teaching Techniques. These manuscripts focus on the how-to portion of science education. That is, JSESD practitioner publications give detailed information on how-to provide science instruction or how-to implement instructional strategies or supports, hence Teaching Techniques. The purpose of this paper is the provide guidance to authors on what to include (or not include) in Teaching Techniques practitioner manuscript submissions to JSESD for successful publication.

Published: September 2021

One of the most important issues in accessible science education is creating a laboratory workspace accessible to blind students or students with visual impairments (VI). Although these students are often provided access to the science lectures, they are usually denied full participation in hands-on laboratory work. Current solutions to this problem focus on providing special accommodations such as asking sighted lab partners to complete the hands-on work. Although the accessibility of laboratory devices in modern science education has been improved in recent years, students with VI often remain passive learners. In this work, we developed a new artificial intelligence tool, the MSU Denver Virtual Lab Assistant (VLA), using Amazon Web Services (AWS), Amazon Alexa Skills Kit (ASK), Alexa smart speaker, and a microcontroller (Raspberry Pi). The VLA can be used as a virtual assistant in the lab in combination with other access technologies and devices. The VLA allows students with VI to perform the hands-on laboratory work by themselves simply using voice control. The VLA can be accessed through any smartphone or Amazon Echo device to assist general science lab procedures. The VLA is designed to be applicable to different science laboratory work. It is also compatible with other common accessible electronic devices such as the Talking LabQuest (TLQ). We believe that the VLA can promote the inclusion of learners with VI and be beneficial to general accessible science education work.

Published: September 2021

This article presents a diagnostic device model, which by using chemical reagents and microfluidics that makes a sort of particle separation and was developed to diagnose an acquired viral immunodeficiency. The device allows to isolate leukocytes and apply a reagent that measures the presence or absence of this virus. The design on the other hand uses tools such as SolidWorks and Autodesk Simulation, which, with the rupture of the membranes and the separation of their components, allows the chemical reaction in the particles and the detection of the virus.

Based on the choice of particle analysis and validating the performance of the fluid maintained in the filter stage, which is represented by 5 flow lines, it shows the movement of 5 particles with the same diameter. Additionally, three tests were performed that varied the diameter of the particles to 5 μm, 10 μm and a larger diameter particle (15 μm). The results show that, with a diameter of 5 μm, the particles move smoothly and the filter can reach the next stage. The particles of 10 μm in diameter presented a normal blood flow, however, an obstruction in the particles of 15 μm in diameter can be observed.

Published: September 2021

This study seeks to determine if variations of carbohydrate intake, before the execution of a short stimulus, may have an impact on lactate concentrations in the athlete's body. Conducting a test with a short stimulus (Abalakov’s jump), 12 athletes were evaluated (elite category), in 4 days of interleaved testing: on the first day they were provided with a special diet (low in carbohydrates), the second day they were asked to perform the test, on the third day they changed the diet (high in carbohydrates), and on the fourth day the test was again performed to compare both moments. For the tests, capillary blood should be extracted from the ear lobe, being the athlete at rest, the subject performs a vertical jump without impulse and followed by this, samples are taken after 1, 3, 5 and 7 minutes. The procedure is the same for both tests, as a result it is observed that in both moments, the type of diet low or high in carbohydrates does not influence the concentration of lactate in the blood capillary of the athletes.

Cnksr2 Loss in Mice Leads to Increased Neural Activity and Behavioral Phenotypes of Epilepsy-Aphasia Syndrome
Authors: Erata Eda , Gao Yudong , Purkey Alicia M. , Soderblom Erik J. , McNamara James O. , Soderling Scott H.
Published: September 2021

Epilepsy Aphasia Syndromes (EAS) are a spectrum of childhood epileptic, cognitive, and language disorders of unknown etiology.CNKSR2is a strong X-linked candidate gene implicated in EAS; however, there have been no studies of genetic models to dissect how its absence may lead to EAS. Here we develop a novelCnksr2KO mouse line and show that male mice exhibit increased neural activity and have spontaneous electrographic seizures.Cnksr2KO mice also display significantly increased anxiety, impaired learning and memory, and a progressive and dramatic loss of ultrasonic vocalizations. We find that Cnksr2 is expressed in cortical, striatal, and cerebellar regions and is localized at both excitatory and inhibitory postsynapses. Proteomics analysis reveals Cnksr2 anchors key binding partners at synapses, and its loss results in significant alterations of the synaptic proteome, including proteins implicated in epilepsy disorders. Our results validate that loss of CNKSR2 leads to EAS and highlights the roles of Cnksr2 in synaptic organization and neuronal network activity.

SIGNIFICANCE STATEMENTEpilepsy Aphasia Syndromes (EAS) are at the severe end of a spectrum of cognitive-behavioral symptoms seen in childhood epilepsies, and they remain an inadequately understood disorder. The prognosis of EAS is frequently poor, and patients have life-long language and cognitive disturbances. Here we describe a genetic mouse model of EAS, based on the KO of the EAS risk geneCnksr2. We show that these mice exhibit electrophysiological and behavioral phenotypes similar to those of patients, providing an important new model for future studies of EAS. We also provide insights into the molecular disturbances downstream of Cnksr2 loss by usingin vivoquantitative proteomics tools.
Does Hemispheric Asymmetry Reduction in Older Adults in Motor Cortex Reflect Compensation?
Authors: Knights Ethan , Morcom Alexa M. , Henson Richard N.
Published: September 2021

Older adults tend to display greater brain activation in the nondominant hemisphere during even basic sensorimotor responses. It is debated whether this hemispheric asymmetry reduction in older adults (HAROLD) reflects a compensatory mechanism. Across two independent fMRI experiments involving adult life span human samples (N= 586 andN= 81, approximately half female) who performed right-hand finger responses, we distinguished between these hypotheses using behavioral and multivariate Bayes (MVB) decoding approaches. Standard univariate analyses replicated a HAROLD pattern in motor cortex, but in and out of scanner behavioral results both demonstrated evidence against a compensatory relationship in that reaction time measures of task performance in older adults did not relate to ipsilateral motor activity. Likewise, MVB showed that this increased ipsilateral activity in older adults did not carry additional information, and if anything, combining ipsilateral with contralateral activity patterns reduced action decoding in older adults (at least in experiment 1). These results contradict the hypothesis that HAROLD is compensatory and instead suggest that the age-related ipsilateral hyperactivation is nonspecific, consistent with alternative hypotheses about age-related reductions in neural efficiency/differentiation or interhemispheric inhibition.

SIGNIFICANCE STATEMENTA key goal in the cognitive neuroscience of aging is to provide a mechanistic explanation of how brain–behavior relationships change with age. One interpretation of the common finding that task-based hemispheric activity becomes more symmetrical in older adults is that this shift reflects a compensatory mechanism, with the nondominant hemisphere needing to help out with computations normally performed by the dominant hemisphere. Contrary to this view, our behavioral and brain data indicate that the additional activity in ipsilateral motor cortex in older adults is not reflective of better task performance nor better neural representations of finger actions.

Wood engineered products are alternatives to the use of timber for civil construction, manufacturing, and the furniture industry. One of these products is the medium density particleboard (MDP) panel, which is made of wood particles and resin under high temperature and pressure. This research produced a prototype to evaluate the use of MDP panels waterproofed by castor oil-based polyurethane resin and Pinus sp. residues treated with CCB preservative for use as a wall coating. The influence of weathering, position of wood panel, and waterproof treatment were evaluated. Panels were made under the requisites of Brazilian Standard ABNT NBR 14810 (2013) and evaluated with international standards. MDP panels met standard requisites, with properties similar to that reported in the literature, indicating the possibility of use as wall coating. Statistical analysis indicated the only significant factor was weathering, which influenced physical and mechanical properties.
Religion in the public sphere
Authors: Grümme Bernhard
Published: September 2021

Religion has become a highly ambivalent phenomenon in late modernity. For some, it is a lasting resource for meaning, even in a highly ideologically plural society. For others, it belongs in the private sphere, not in the public sphere. What both would probably share, however, is the assumption that a state religion would be in contradiction to the promises of freedom and autonomy of modernity. But where is the place of religion in a democratic society? The text discusses this highly complex question in an examination of two theories that have shaped debates in the field like few others. From this discussion, further perspectives for a theologically founded position that is responsible in terms of democratic theory are given in conclusion.
Natural Resources as a Factor in Production of a Regional Tourist Product and in Creation of Tourist Destinations
Authors: Saryan Akop A.
Published: September 2021

Introduction. Geographical location of natural resources is a determinant of localization of tourism. Based on the results of the research conducted, the article studies the theoretical and practical aspects of transformation of natural resources into a factor in production and consumption of a tourist product, as well as those of formation of directions for the flow of tourists.

Materials and Methods. Materials of surveys of potential tourists conducted by independent research firms, Russian and foreign scientific publications and expert assessments, as well as the results of research carried out by the author of the article were used as the information base of the study. To assess the role and place of natural resources in the production and consumption of a tourist product, content analysis, as well as structural and functional analysis were employed. Using the methods of logical interpretation, statistical data processing, tabular and graphical methods, a scheme of transformation of natural resources into a factor in production and consumption of a tourist product has been devised and the degree of consumer preference for a tourist destination has been identified.

Results. The study has identified problematic aspects of the use of natural resources in tourism, one of which is the underestimation of such resources as a basic factor in production and consumption of a tourist product, which negatively affects the level of economic feasibility of tourism development programs. The role of natural resources in formation of tourist needs and directions of the flow of tourists has been revealed. Conclusions have been drawn about the growing need for tourism with the predominance of the natural component of the tourist product and about the gradual formation of preconditions for local manifestations of overtourism and tourism phobia, in particular in the resorts in the South of Russia. The author has formulated proposals aimed at improving the economic feasibility of domestic tourism development programs.

Discussion and Conclusion. Availability of natural resources is the primary basic condition for production and consumption of a tourist product. Significant costs for their transformation into tourist goods increase the requirements for the level of reasonableness of managerial decisions. The research results can be applied in strategic and medium-term planning of the development of domestic tourism in Russian regions on the basis of their natural potential.

Published: September 2021

In the modern minds of the advanced ecology and safety of food products control, it is relevant the development of antimicrobial biodegradable packaging. The article presents the results of the antagonistic action of nanodispersed titanium dioxide powder (TiO2) at the warehouse of biodegradable packaging for bakery products on the living of microorganisms (Escherichia сoli, Bacillus subtilis, Candida albicans, Aspergillus niger). It is known there are developments on the use of antimicrobial substances of both organic and inorganic origin, the microbiological action of the substances used have an effect on pathogenic, opportunistic, fungi, gram-negative and gram-positive bacteria. We found that the introduction of 1% TiO2 r into the molding solution allows to give the package antibacterial properties, as it inhibits the development of Escherichia coli and Bacillus subtilis, as there is a delay in the growth of their colonies compared to the sample without packaging with TiO2. According to the results of provocative testing, biodegradable packaging with a content of 1% TiO2 has an inhibitory effect on Bacillus subtilis. In addition to antimicrobial properties, the package under study must also have barrier properties, so the vapor permeability of the presented package was determined. The study results show that the addition of 1% TiO2 slightly reduces the vapor permeability, but the increase in the concentration 2–5% of TiO2 causes an increase in vapor permeability from 4.7 to 5.2 mg / (m∙h∙kPa). The vapor permeability of the presented biodegradable antimicrobial packaging is due to the presence of pores, the number and size of which were determined experimentally. Thus, nanodispersed TiO2 in the amount of 1% in the molding solution of the biodegradable coating is an effective antimicrobial component for antimicrobial coatings, which does not impair their barrier properties.

Published: September 2021

The problem of human aging is very relevant today. The mechanisms of aging are closely related to the decrease of such a protein substance as collagen in the human body. One of the possibilities for restoration the amount of this vital component is the use of collagen-containing juice products of everyday use in the diet. Taking into account the relevance and prospects of this issue, the direction of further work has been chosen accordingly. The purpose of the research is the use of collagen in the formulation of an assortment of juice products based on fruit and vegetable raw materials. To achieve the goal of the study we formulated the tasks that allowed us to research the range and quality indicators of different types of collagen of plant and animal origin (tomato, beef, pork and fish) as well as to justify the choice of the most preferred collagen sample for drinks. We have determined the optimal amount of this biologically active additive to ensure the required quality of the finished product. We have investigated the preservation of the active properties of various types of collagen in fruit and vegetable drinks. As a result of the studies performed it has been shown that beef collagen is the most acceptable and retains its active properties in an amount of 5% to the mass of the drink; it adds salt, alcohol, alkaline protein fractions according to its fractional composition. It has been shown that the amino acids methionine, tryptophan and hydroxyproline which confirm the presence of collagen in the product are contained in ready-made juice drinks enriched with collagen of beef origin. The formulations of fruit and vegetable drinks with the addition of collagen have been developed accordingly. A comparison of the organoleptic and physicochemical characteristics of finished drinks with the requirements of normative and technical documentation (DSTU 4283-2007) was carried out and their full compliance was proved.

Authors: Synytsia O. , Vinnikova L.
Published: September 2021

The poultry production is growing rapidly every year. Having a rapid pace of development and reproduction, and greater affordability, the poultry products are in high demand from the population. In this regard, the industry is in demand for deep processing of poultry meat, which is not only economically feasible, but also makes it possible to expand the scope of use of this product. The complex morphological structure of the poultry complicates its use as the main raw material for meat products, and poultry meat is mainly sold in the form of natural semi-finished products with a limited shelf life. It is possible to expand the range of poultry products through the production of canned food. A new technology for the production of pasteurized canned poultry meat was developed at the Department of Meat, Fish and Seafood Technology of the Odessa National Academy of Food Technologies. This technology involves hydrothermal treatment of the raw materials, hot boning, mixing of components of the formulation and pasteurization. This article reveals the issue of the first stage of production, namely the establishment of rational meat hydrothermal treatment conditions. The problem of choosing the heat treatment conditions is extremely important, because depending on the process conditions and the final heating temperature, the transformation of the components and the properties of the finished products differ significantly. The paper studies the effect of temperature in the range from 65 to 95°C in 5°C increment on the rate and degree of cooking of collagen, the formation of the required structure of the product (hydrogel base filled with individual muscle fibers), hardness and tenderness of meat. It is established that the optimal processing temperature of poultry meat is 65°C. The meat processed at this temperature had the highest degree of collagen cooking, the highest viscosity of the broth, the lowest shear stress, and the best organoleptic characteristics.

The use of local non-conventional raw materials will allow significantly enriching unfortified fruit wines with ascorbic acid and phenolic substances and make it possible to obtain products with increased biological value. The paper considers black elderberries grown in the forest steppe zone of Ukraine. It has been determined that they contain 12–13% of soluble solids, 6.9–8.1 of sugars, 0.93–1.2% of titratable acids, 33.4–53.1 mg/100 g of ascorbic acid, and 2331–3888 mg/100 g of phenolic substances. The pressing process and its dependence on the method of treating berries have been studied. It has been proved that juice extraction from black elderberries is the highest when they are pretreated with heat at 98±2°C for 3–5 minutes, with 15% of water added. Depending on the treatment method, juices retain ascorbic acid (15.8–33.4 mg/100 g) and phenolic substances (2538–3888 mg/100 g), which indicates their high biological value. Juices like these can be used to improve the biological composition of blended juices and wines. To ferment high-sugar black elderberry must, active dry yeast was used, namely the yeast races EC-1118 of the genus Saccharomyces bayanus (France) and ENSIS LE-1 or ENSIS LE-5 of the genus Saccharomyces cerevisiae (Spain). The musts were fermented for 36–62 days. The period of vigorous fermentation coincides with the period of initial fermentation and ends in 9–10 days, with accumulation of 12–14% of ethanol by volume. Unfortified wine materials obtained from black elderberries contain 22–38.3 mg/100 g of ascorbic acid (its content in wine materials is by 7.8–49.55% lower than in fresh berries) and 1750–3510 mg/100 g of phenolic substances (which is lower by 9.7–39.6%, as compared with fresh elderberries). The active acidity of black elderberry wine materials is 3.90–4.09 pH units, depending on the yeast race. A similar difference has been found for the redox potential (160–176 mV), which indicates that the wine materials from black elderberries are low-oxidised. The intensity of colour of the wine materials obtained from black elderberries (D420 + D520) varied from 3.08 to 3.20, and the colour shade from 0.88 to 0.92, which is typical of young red wines. These wine materials can be used to increase the quality and biological value of blended wines.

The article presents the theoretical basis and practical aspects of the using of binary compositions of uronid polysaccharides in the technology of culinary products from aquatic organisms in jelly fillings. The relevance of the composition of natural high molecular weight polysaccharides, such as sodium alginate and low-esterified pectin, to promote the improvement of sensory characteristics of culinary products from aquatic organisms in the menu of fish restaurants is shown. The objectives of the study were to obtain a jelly filling of viscous consistency, followed by the formation of a stable, elastic gel for using in the technology of aquatic products. Obtaining a jelly filling involves det-ermining the parameters of the preliminary preparation of hydrocolloids; study of the influence of technological par-ameters on the sensory characteristics of the gel. Creating a dry mixture of sodium alginate and low-esterified pectin with salt and sugar was necessary to ensure the dispersion of particles of dry hydrocolloid powders to prevent sticking when swelling in water at a temperature of 18-20 ° C for 15 minutes. Intense swelling of the mixture occurs in the first 10 minutes of hydration.The degree of swelling reaches 5.8%; further increase in time has almost no effect on the swe-lling process. The swelling kinetics of the hydrocolloid mixture was evaluated by determining the tangent of the angle of inclination tangent to the curve describing the degree of swelling. The rational mass fraction of calcium ions for the formation of a transparent gel of stable, homogeneous, elastic consistency, which is 0.3-0.4% of the 10% solution of calcium chloride, was experimentally established. It was studied that dispersions with a mass fraction of a mixture of alginate: low-esterified pectin substances - 1.8% have a viscous consistency with a dynamic viscosity of less than 0.94 Pa • s, which is important for the implementation of technological operations of transportation and packaging of jelly fillings. The conditions and speed of gelation, which provide the finished culinary products with high sensory cha-racteristics and elastic consistency due to the regulated melting temperature, which is provided by the composition of uronide hydrocolloids, have been studied. It was found that the strength of the gel more than 140 g forms a mixture of hydrocolloids with a mass fraction of from 1.6 to 1.8%.

ABSTRACT Objectives: to understand care for the spiritual dimension provided by caregivers in a Nursing Home. Methods: this is a qualitative research, carried out in a geriatric center of a philanthropic hospital in the city of Salvador, Bahia. Eighteen formal caregivers participated, through a semi-structured interview, between January and February 2019. The data were analyzed in the light of Jean Watson’s Theory of Transpersonal Caring. Results: formal caregivers discuss the spiritual dimension based on older adults’ religious beliefs, encourage religious practices and exercise spiritual care according to older adults’ physical, emotional and spiritual demands. Final Considerations: formal caregivers understand that older adults’ religious or spiritual experiences should be included in their work routine. Care for the spiritual dimension occurs by stimulating faith in God, encouraging religious practices and embracing their beliefs in the face of physical, emotional and spiritual demands.

ABSTRACT Objectives: to analyze the contents on patient safety in the training of nursing technicians. Methods: a documentary study, conducted in three technical nursing courses at a public university in northeastern Brazil, based on the Multi-Professional Patient Safety Curriculum Guide, published by the World Health Organization. Results: we found that, of the 26 subjects in each course, the tracking terms were found in 22 subjects in the A/C courses, 23 in the B course. The topics of the guide with the highest number of terms were the improvement in medication safety, with 85 terms (22.6%), and Infection prevention and control, with 75 terms (20%). The contents do not express the comprehensiveness of patient safety education; some subjects had this focus, while others did not. Conclusions: the documents revealed gaps in the contents related to patient safety and demonstrated that they are addressed only in the course syllabus and discipline plans.
Estrutura remuneratória dos servidores ativos civis do Executivo federal
Authors: Profili Enzo Bastos
Published: September 2021

Resumo A administração pública federal passa por um momento de aperto fiscal, e, como o gasto com pessoal é um dos maiores componentes da despesa, mostra-se importante avaliar sua composição. Para isso, este artigo analisa detalhadamente a estrutura remuneratória das carreiras do Executivo federal civil. O texto mostra que a maioria dos servidores federais civis está entre os 10% mais bem remunerados do país, recebendo, em certos casos, um prêmio salarial com relação à esfera privada. Analisamos também que servidores com as mesmas atribuições têm remuneração significativamente diferente, dependendo do órgão da administração direta ou da entidade da administração indireta em que trabalham. Além disso, evidenciamos a prociclicalidade da despesa com pessoal ativo do Executivo, possivelmente liderada em tempos de recessão. Dito isso, uma agenda de reforma administrativa é importante para racionalizar as carreiras do serviço público, trazendo a remuneração à realidade brasileira e premiando servidores de alto desempenho por meio de metas de médio e longo prazos.

Published: September 2021

Resumo Este artigo analisa os determinantes do diferencial de remuneração entre as carreiras do Poder Executivo do estado de Minas Gerais, utilizando um modelo de regressão linear cujas variáveis explicativas foram elaboradas com base em diferentes abordagens teóricas acerca da determinação dos salários: teoria do capital humano, teoria da segmentação dos mercados, teoria da discriminação e sociologia das profissões, além de considerar as especificidades do setor público. A escolha da unidade federativa se justifica pela relevância no cenário nacional e pela difícil situação fiscal vivenciada nos últimos anos. A investigação é guiada pela hipótese de que as diferenças salariais no setor público refletem não só a qualificação e a experiência no trabalho, mas também reproduzem distorções típicas das estruturas socioeconômicas e político-burocráticas. Os resultados corroboram a hipótese adotada e sugerem que a estrutura relativa de salários no setor público constitui uma manifestação concreta das diferenças de recursos políticos disponíveis às carreiras, do prestígio social das profissões e de aspectos estruturais da desigualdade de gênero.
