ON THE USE OF HARMONIC SIGNALS FOR SIMULATING THE OPERATION OF MEASURING AND CORRECTING OPTICAL SYSTEMS IN A TURBULENT ATMOSPHERE
Authors: ЛУКИН В.П.
Published: August 2024

Исследуется вопрос корректности использования гармонического сигнала для моделирования работы измерительных фазовых систем, например систем адаптивной оптики, измеряющих и корректирующих турбулентные искажения. Выполнены оценки временно́й эволюции фазовых искажений для оптической волны при её распространении в турбулентной атмосфере. При анализе эволюции фазовых искажений в оптической волне, обусловленных действием турбулентности, рассчитывается отношение дисперсий первой и второй производных для приращения фазовых искажений за определённый временной интервал. Величина этого отношения сравнивается с этой же величиной при моделировании временны́х искажений при применении гармонического сигнала. Оказалось, что при моделировании временно́й эволюции фазовых искажений с использованием гармонических сигналов необходимо учитывать не только первую производную этого приращения, но и как минимум вторую производную.

The question of the correctness of using a harmonic signal to simulate the operation of measuring phase systems, for example, adaptive optics systems that measure and correct turbulent distortions, is investigated. The time evolution of phase distortions for an optical wave as it propagates in a turbulent atmosphere is estimated. When analyzing the evolution of phase distortions in an optical wave caused by the action of turbulence, the ratio of the dispersions of the first and second derivatives is calculated for the increment of phase distortions over a certain time interval. The magnitude of this ratio is compared with the same value obtained in modeling temporary distortions when using a harmonic signal. When modeling the time evolution of phase distortions using harmonic signals, it is necessary to take into account not only the first derivative of this increment, but also, at a minimum, the second derivative.

Authors: РЕЗНИК А.Л. , СОЛОВЬЕВ А.А.
Published: August 2024

Проведено сопоставление по быстродействию различных многоэтапных процедур локализации сигнальных точечных источников, обнаруживающих себя генерацией в случайные моменты времени мгновенных импульсов. Результаты исследования подтвердили высокую эффективность универсальной процедуры многоэтапной локализации равномерно распределённого точечного источника в тех случаях, когда отсутствуют дополнительные априорные сведения о мощности и возможном расположении разыскиваемого объекта в пределах поискового интервала. Предложен и обоснован новый квазиоптимальный метод локализации, повышающий эффективность поиска при наличии априорных сведений о функции распределения и мощности разыскиваемого источника

A speed comparison is made of various multi-stage procedures for localization of pulsed-point sources that reveal themselves by generating instantaneous pulses at random times. The results of the study confirm the high efficiency of the universal procedure for multi-stage localization of a uniformly distributed point source in cases where no additional a priori information about the power and possible location of the searched object within the search interval is available. A new quasi-optimal localization method that increases the search efficiency in the presence of a priori information about the distribution function and power of the searched source is proposed and justified.
The issue of conversion to Orthodoxy of non-orthodox citizens of the Russian Empire in the second half of the 19th century according to journalistic sources (with M. K. Kabanova and E. V. Melkova as examples)
Authors: Vladimirova Maria
Published: August 2024

The article is devoted to the problem of the conversion of non-believers of the Russian Empire to the Orthodox faith in the second half of the XIX century. These gentiles had to resist their society in particular, their families, or break social ties. Based on journalistic sources, the author reconstructs the activities of Maria Kosminichna Kabanova and Ekaterina Vasilyevna Melkova, who show examples of individual missionary service of women carried out in the 1870s-1890s in the Orenburg and Samara dioceses, respectively. The article highlights the ways in which missionaries carried out their activities and examines the features of their interaction with the structure of the Orthodox Missionary Society. Basing on the example of the missionaries’ service it is noted how important it was for the Russian Orthodox Church to organize shelters for the newly converted orthodox people so that they could safely establish in their faith. Because of this, the emphasis is put on the fact that the shelters created by the missionaries were not an artificial phenomenon, but arose in response to an existing need. M. K. Kabanova and E. V. Melkova indicated with the help of their service, which occurred at the same time, certain changes which took place in the society because of the Great Reforms. It is seen both through the tendency of the people to acquire the desire to serve the Church and the mission and through the newly opened possibility to change their social status of women.

Published: August 2024

The article discusses the issues of planning and resource management in the process of testing software systems. The paper presents the ACC analysis method used at Google to optimize the distribution of efforts for testing different parts of the system. Extending the method by adding a fourth characteristic - actors (roles of system users) – allows for a more flexible assessment of action requirements and user skill levels. Illustrative examples of system attributes and components help understand the principles of the method. The work proposes a new approach to risk management and process improvement in testing software systems in a multidimensional space. The effectiveness of applying the enhanced ACC analysis method using a risk-oriented approach was demonstrated using the example of a control system for technological operations in the repair of electric motors, for which attributes, components, actors were identified, opportunities at their intersection were analyzed, and testing was conducted, which helped improve the system's quality.
Ontology-based Neurointerface IoT Integration Approach
Authors: Labutin Ivan Aleksandrovich , Chuprina Svetlana Igorevna
Published: August 2024

Recently, there is a surge of interest in employing neurocomputer interfaces for a control contours implementation, especially for different infrastructures of Internet of Things. However, due to a low-level nature of such devices and related software tools, neurointerface integration with a large variety of IoT devices is quite a tedious task, and the one that requires a lot of knowledge in the neuroscience and signal processing to boot. In the paper, we propose an ontology-driven solution for facing the upcoming challenges of unified integration of brain-computer interfaces into IoT ecosystems. We demonstrate an adaptable mechanism for integrating brain-computer interfaces into the Internet of Things infrastructure by introducing an intermediate layer – a smart mediator that will be responsible for communication between the environment and the neurointerface. The mediator’s software is generated automatically, and this process is driven by a managing ontology. The proposed formal model and the system's implementation are described. The approach we have developed enables researchers and engineers without strong background in brain–computer interface to automate the integration neurointerfaces with different infrastructures of Internet of Things.

Authors: Le Thi Thanh Hue , Vinh Vu Duy , Pham Tien Dat
Published: August 2024

The Hai Phong coastal area is one of the places that is often affected by storms and tropical depressions, with significant impacts on hydrodynamics and geomorphological changes. The influence of typhoons on hydrodynamic conditions in the Hai Phong coastal area has yet to be thoroughly studied. Accordingly, the above study has evaluated the influence of storms with different trajectories on the hydrodynamic field in the Hai Phong coastal area under complex, non-linear impacts to contribute to a better understanding of the influence of storms on hydrodynamic processes and to improve research capacity on hydrodynamic regimes in coastal estuaries using modeling tools. Observational and reanalysis data from global sources were collected systematically and homogeneously to create open boundary conditions (time-serial) for the model. The NESTING method created sea boundary conditions for the model from another model with a larger grid outside. The Delft3D model system was set up with five vertical layers in Sigma coordinates and was validated, showing a fair agreement with measurement data at some places in the study area. Results of scenarios showed typhoons have an extreme impact on hydrodynamic conditions in the Hai Phong coastal area, especially raising the water level and increasing the flow velocity and wave height in the coastal area. Different typhoons effect the hydrodynamics differently, but they all share that the estuary areas with narrow channels are more strongly affected than the remaining areas. When the typhoons make landfall at the Lach Huyen estuary in Nam Trieu, the flow velocity can be up to 0.8–1.2 m/s (an increase of 0.5 m/s compared to the flow velocity in normal conditions), and the wave height can be up to 1.2–2.5 m (a rise of 0.4–2 m compared to the wave height in without typhoon).

Published: August 2024

The total organic carbon (TOC) in the marine environment, which includes dissolved organic carbon (DOC) and particulate organic carbon (POC), is essential to the ocean’s carbon cycling system. This research was carried out in 2023 to assess the variation in organic carbon concentration in the environment of Cua Luc Bay and Ha Long Bay at 22 survey stations. The results show that the average concentrations of DOC and POC are 1.59 ± 0.21 mgC/L and 0.74 ± 0.35 mgC/L, respectively. However, DOC and POC concentrations are still considered low compared with other rivers and estuaries in Vietnam and worldwide. The ratios of organic carbons like DOC/POC and POC/Chl-a in this study area were also calculated. The ratios’ results are evidence of many fluctuations in the water environment in Ha Long Bay, Vietnam, in 2023.
Motherhood, Trauma and Justice: A Critical Look at Black Women's Reentry Pathways
Authors: Davis Leslianne
Published: August 2024

Objectives: This article seeks to investigate the particular problems that Black mothers with justice involvement experience upon reentry and to offer a more effective framework for their assistance.
Hypothesis: Traditional reentry frameworks fail to address the complexity that emerges from the combination of race, gender, and trauma experienced by Black mothers.
Methods: The article conducts a critical intersectional analysis using Critical Race Theory (CRT), Black Feminist Theory (BFT), and Trauma-Informed Care (TIC). This study analyzes previous research and combines the findings from each framework.
Results: The research demonstrates three essential things: that systemic racism in the criminal justice system disproportionately imprisons Black women, contributing to unfavorable reentry experiences; that Black women show perseverance and opposition to carceral regimes, but their unique perspectives and agency are frequently left unattended; and that trauma is common among Black women and has an immense impact on their reentry experiences. The requirement for trauma-informed support programs is vital.
Conclusion: Based on the findings, a re-conceptualized reintegration support framework is presented, focusing on racial justice, gender equality, and the well-being of Black women and their families.
“So many forms of loss”: Cumulative grief among formerly incarcerated people
Authors: Ward Olivia , Dewey Susan
Published: August 2024

Objectives: The review aims to explore nuanced phenomena, compound loss and cumulative grief that previously incarcerated individuals experience because of their incarceration.
Hypothesis: Compound loss and cumulative grief manifest in multiple ways that differ based on the individual and their experiences before, during, and after incarceration.
Methods: The study adopted a secondary research design using transcripts from interviews with individuals on parole that were collected from a previous study conducted by Dr. Susan Dewey and reanalyzed for the present study.
Results: The review presents the findings from the first author’s analysis of multiple transcripts focusing on topics from a previous study relating to life before, during, and after prison. The findings showed three primary forms of compound loss: positive loss – loss of problematic relationships, negative loss, and transformative loss. Participants of the present study experienced one or more forms of loss, resulting in experiencing compound loss. Positive loss encompassed losing a fractious romantic relationship and or substance misuse. Negative loss encompassed losing reputation, time, relationships, trust, and freedom/independence. Transformative loss encompassed improved relationships, improved self-worth and self-awareness, and advocacy for others or self. Cumulative grief and compound loss can have negative impacts on reentry success for many, as they are unable to properly cope with the pile-on effects of loss.

Published: August 2024

Abstract: Nitrogen (N) fertilization in citrus orchards is prone to significant environmental losses. Managing nutrients for sustainable development and optimizing nitrogen use efficiency (NUE) are key tasks in modern agriculture. NUE depends on N uptake and assimilation. In addition to intrinsic fertilizer use efficiency, we evaluated plant growth, nitrate reductase (NRase) activity, and the nutritional status of citrus plants fertilized with different N sources [calcium nitrate (CN), ammonium nitrate (AN), and ammonium sulfate (AS)]. After 240 days, plants supplied with either CN or AN exhibited higher biomass production and N accumulation in the leaves than those fertilized with AS. The supply of ammonium-containing sources (AN and AS) reduced the substrate pH, in which those with AS exhibited lower N partitioning to the leaves, as well as reduced the absorption and accumulation of magnesium and phosphorus. NRase activity was higher in plants supplied with CN or AN compared to AS, and CN fertilization provided the greatest NUE. The data demonstrated that citrus plants fertilized with sources containing nitrate increased the NUE from 10 to 25% and consequently had greater growth compared to those fed with AS.

Published: August 2024

Abstract: The aim of this study was to describe the main characteristics of development, production, and postharvest of the new cultivar of the Prata subgroup, ‘VTP Hayashi’, that is a natural mutation originating from ‘SCS451 Catarina’. The plants of VTP Hayashi showed greater height and diameter of the pseudostem and the fruits are longer, heavier, and more uniform in the cluster, characteristics that differ from ‘SCS451 Catarina’. The development and production cycles and the susceptibility to fungal diseases resemble those of ‘SCS451 Catarina’. At maturity stage 6, it presented average contents of soluble solids of 28.2ºBrix and titratable acidity of 0.69% of malic acid, higher than ‘SCS451 Catarina’. The selection of this cultivar was due to the position of the inflorescence in the vertical direction, giving it a better fruit development.

Published: August 2024

Abstract For the Caatinga vegetation, it has not yet been definitively established which adaptive strategies best define the functional groups of woody plants and which syndromes emerge from the relationships between functional traits to achieve success in a semi-arid tropical region. To fill some of these gaps, we analyzed a specific set of characteristics that make up the LHS scheme of the plant ecological strategy (leaf-heigh-seed). The LHS scheme captures the functional niche of plants regarding the functional traits specific leaf area (SLA), plant height (HE), and seed mass (SM). We associate wood density (WD) to this scheme because this trait is a key feature for the identification of functional strategies in seasonally dry vegetation such as the Caatinga. We measured these characteristics in eight woody species and classified them according to their leaf phenology into deciduous and evergreen. The experiment was carried out between December 2017 and November 2018 in Caatinga areas located in the municipality of Barra de Santana, PB, a semiarid region of Brazil. Using cluster analysis, principal component analysis (PCA) and Pearson correlation analyses, we found significant relations between SLA and SM, and HE and WD. The SLA was the main predictor of plant strategy in the Caatinga. According to this characteristic, we identified two functional groups: species with a low SLA and species with a high SLA. We also recognized differences between deciduous and evergreen species based on the same trait. The traits measured, which represent the axes of the plant ecological strategy scheme LHS and wood density, are efficient in the discrimination of functional groups in the Brazilian semiarid. These groups relate to leaf phenology of woody species in this vegetation.

Published: August 2024

Abstract Genipa americana (Rubiaceae) is a fruit tree with broad phytogeographic domain and suitable for different silvicultural systems in the tropics. The knowledge associated with the relative growth rate of species such as G. americana, provides important guidelines for the effective establishment and survival of seedlings after planting in the field. In this study we investigated differences in growth, biomass allocation and photosynthesis of seedlings originating from different mother plants of G. americana in southern Bahia, Brazil. For this, we evaluated fifteen variables associated with carbon balance at the whole plant and leaf scales of twelve G. americana progenies. All seedlings grew over a period of 198 days under similar microclimatic conditions with approximately 65% full sun. Our results showed significant differences in the relative growth rates (RGR), with the highest and lowest mean values being 29.0 and 38.0 mg g-1 day-1, respectively. Differences in RGR between G. americana progenies were highly related to differences in biomass allocation at both whole plant and leaf scales. From a practical point of view, we demonstrate that the selection of mother plants to produce seedlings with higher growth rates, and consequently greater establishment capacity in field plantings, can be made from evaluations of growth and biomass allocation variables at the whole plant scale.

Published: August 2024

Abstract The aim of this study was to investigate the DGAT1 gene polymorphism and its effects on lamb weight in kazakh and tajik sheep breeds. A total of 97 blood samples were collected from purebred (еdilbay х еdilbay) and crossbred lambs (еdilbay x gissar) breеd by the Baiserke Agro Scientific and Production Center in the Talgar District of the Almaty Region of Kazakhstan. Animals were genotyped for DGAT1-AluI polymorphism using the polymerase chain reaction-restriction length polymorphism (PCR-RFLP) method. The result of PCR-RFLP showed that purebred (еdilbay х еdilbay) sheep had three genotypes (CC, CT and TT) and crossbred sheep had two genotypes (CC and CT). The predominant genotype was CC with a frequency of 0.70 and 0.58 in purebred sheep and crossbred sheep breeds, respectively. The DGAT1 gene showed no significant association with live weight of lambs at different times in both breeds studied. However, the study showed that the CC genotype produced higher live weight at day 60 in purebred sheep (CC: 33,668 kg and CT: 32,444) and at day 120 (CC: 41,487 and CT: 40,929) in crossbred lambs. The present study was the first to investigate the polymorphism and relationships between genotypes and lamb live weights for DGAT1 gene in sheep breeds, purebred and crossbred. We conclude that further comprehensive investigations should be done for the exact evidence of the effects of DGAT1/Aluı polymorphism on lamb live weights.
Human resources churning dependent on the economy: Society’s impact on institutions?
Authors: Pirrolas Olga Alexandra Chinita , Correia Pedro Miguel Alves Ribeiro
Published: August 2024

Abstract Purpose: This essay presents the results of a theoretical research using the existing literature on human resource churning within the economic context. The research examines how institutions and society address human resource churning from the economy. To accomplish this, two specific objectives were established: the examination of the key variables impacting churning within the economic context, and the creation and analysis of a theoretical model. The research question that emerged was: “How do institutions and society deal with the occurrence of churning arising from the economic context?” Originality/value: The relevance of this essay rests in its potential to contribute to the existing literature and enhance the advancement of know-ledge in a field that despite its complexity and relevance remains relatively underexplored in the area of human resource management. In this regard, understanding the impact that the economic context plays on the phenomenon of human resource churning is a key aspect for organizations to take mitigation measures. Design/methodology/approach: It follows a theoretical approach by means of a literature review which has allowed the exploration, analysis, deepening and broadening of the existing literature. Findings: Upon analysis of the results, it was found that during periods of economic recession the churning rate is lower compared to periods of economic recovery. As a result, organizations need to adapt their policies to the economic context in order to retain their employees and avoid costs arising from replacements (churning).
Risks of technological advance and the Anthropocene feedback process in energy and agriculture
Authors: Bezerra Marcio Eduardo Garcia , Marquesan Fábio Freitas Schilling , Figueiredo Marina Dantas de
Published: August 2024

Abstract Purpose: This article aims to highlight the existence of an Anthropocene feedback process originating from the pressures of human actions on Earth, particularly the adoption of novel technologies that bring risks and negative environmental impacts in two strategic economic sectors: energy and agriculture. Originality/value: We defend the argument that each technological advance generates new associated risks, increasing the negative pressure on terrestrial ecosystems. This argument draws inspiration from the discourse on the “risk society” (Beck, 2011), which deals with the unquantified uncertainties linked to technological progress. It also aligns with the concept of the Anthropocene (Crutzen & Stoermer, 2000), which examines how human actions and organizations impact the Earth’s system. The discussions demonstrate that uncertainty remains an inherent facet of human activities, thus perpetually subjecting such actions to risk. Design/methodology/approach: We employ a theoretical essay approach to discuss evidence that underscores the challenges posed by technological advancements in the energy and agriculture sectors, notably expressing human-induced environmental impacts. Findings: By analyzing technological advances in energy and agriculture, we substantiate the existence of the Anthropocene feedback process. This analysis contradicts the notion of a favorable “good Anthropocene” (Asafu-Adjaye et al., 2015) and challenges the misconception that technological progress alone can sufficiently mitigate the repercussions of human activities on Earth.
Solidarity economy and its institutionalization stage: public policy contributions
Authors: Silva Daiane Lima da , Ferreira Vicente da Rocha Soares
Published: August 2024

Abstract This study aimed to describe how public policies have contributed to the institutionalization process of the solidarity economy field. The study focused on four state public policies related to the solidarity economy. The data was collected through documentary research and interviews, and content analysis was conducted. The study examined the implementation of the instruments the selected public policies established and their contribution to fostering and supporting solidarity economic enterprises. The study identified actions related to commercialization, technical support, formalization, access to credit, and intra-governmental actions. The Tolbert and Zucker model was used to analyze the institutionalization process. The study concluded that two cases were in total institutionalization because they provided social recognition and legitimation to the solidarity economy through their actions.
A typological study based on the attributes of solidarity economy workers for the improvement of public policies for job and income generation
Authors: Anjos Eliene Gomes dos , Ramos Carlos Eduardo Crispim de Oliveira
Published: August 2024

Abstract This article presents a typological study based on the personal attributes and economic activities of associates of solidarity economy enterprises. The main focus is on the different social actors that integrate the different types of solidarity initiatives, intending to demonstrate their multiple demands and challenges. We used Multiple Factor Analysis (MFA) with variables extracted from the sample survey of the partners of the solidary economy, carried out by Senaes, in 2013, in the five regions of Brazil. MFA allowed summarizing and hierarchizing the results of the statistical data modeling, defining the existence of common factors and dissimilarity among the 2,895 respondents. The formed clusters resulted in three types, named family farmers (type 1), traditional peoples and communities (type 2), and associated urban workers (type 3). The characterization of the types and their demands may constitute a tool to provide subsidies to formulators and executors of public policies for job and income generation since it allows the targeting of actions that reflect the needs and specificities of each grouping.
The dignity of work and the social economy in Portugal
Authors: Hespanha Pedro
Published: August 2024

Abstract The article aims to provide a sociological analysis of how the social economy in Portugal structures labor relations. Defining itself as an economy centered on people and not on capital, the social economy claims an active role in the search for social justice and decent work for all and in its contribution to the democratization of the economy. However, the enormous diversity of forms through which it presents itself requires a more detailed analysis of the labor relations within each of these forms and particular attention to the diversity of the contexts in which they developed. For pragmatic reasons, the analysis focuses only on Social Economy organizations and not on those of the social and solidarity economy since there is a lot of information regarding those, and they represent a very relevant sector in Portuguese society due to their function, capacity for employment, and dynamism. The methodology combines information from qualitative studies with results from surveys carried out in organizations. The conclusion reveals the existence of a set of difficulties in recognizing equal dignity to the work of members and wage earners: on the one hand, due to a double process of adverse inclusion of organizations in the market economy and its institutionalization through state policies; on the other hand, due to excessive and unworthy use of salaried work in carrying out the tasks of organizations, without any participation or incentive in their management.

Abstract This study aimed to validate the methodology of immunochemiluminescence (CLIA) using an enzyme-linked immunosorbent assay (ELISA) to determine serum progesterone (P4) concentrations in non-pregnant multiparous dairy (12 Holstein cows) and beef (18 Nellore cows) cows during the estrous cycle. Cows with corpus luteum were chosen for estrus and ovulation synchronization by administering 500 mcg of cloprostenol. After luteolytic application, the animals were subjected to ovarian ultrasonography (US) daily to verify ovulation (day zero of the cycle) and two blood samples were collected for P4 determination using CLIA and ELISA. Samples were centrifuged to obtain serum and frozen at -20 °C for later measurement. ELISA and CLIA values were compared using the paired t-test, regression, analysis of variance, and coefficient of determination (R2) to verify sensitivity and linear correspondence. The P4 concentration determined by both methodologies showed a similar profile; the P4 profiles were higher in beef cattle than in dairy cattle. The correspondence between the methodologies resulted in a high quotient for R2 the P4 profiles. It was concluded that CLIA can be used for hormonal determinations of bovine serum P4. CLIA showed a high linear correspondence with ELISA values and can thus aid reproductive biotechnologies for hormone determination.

Abstract The aim of this study was to determine the endothelial cell morphology in the different regions of healthy bovine corneal endothelium using optical microscopy. Twenty eyeballs from 10 male Brangus cattle, aged 24 months, were studied. The corneal endothelium was stained with the vital dye alizarin red and then examined with an optical microscope and photographed. Thirty endothelial cells from each corneal region were included in the analysis. Endothelial cell morphology was analysed in the central, superior, inferior, lateral and medial regions of the cornea. Comparisons between regions were performed using repeated measures analysis of variance (ANOVA). Differences were considered statistically significant at P < 0.05. Normal endothelial cells were mainly hexagonal (83.7%), pentagonal (7.45%) and heptagonal (8.8%), with a minimal number of cells of other shapes present. No statistical differences were observed in the endothelial cell morphology when comparing different regions of the cornea. Regarding endothelial cell morphology, there were no differences between the corneal regions.

Abstract This study aimed to estimate genetic parameters for traits of in vitro embryo production (IVEP) of Nellore and Senepol cattle. Data from 1,247 rounds of in vitro fertilization (1,029 Nellore, 218 Senepol) were used, totaling 148,311 oocytes (116,972 Nellore, 31,339 Senepol), 47,301 embryos (38,722 Nellore, 8,579 Senepol), and 6,323 pregnancies (5,534 Nellore, 789 Senepol). The variables percentage of viable oocytes (Pooc), percentage of cleaved embryos (Pcleav), percentage of produced embryos (Pemb), percentage of pregnancy (Ppreg) per round per bull, mean number of viable oocytes per donor (MOD), mean number of embryos produced per donor (MED), and mean number of pregnancies per donor (MPD) were analyzed from data provided by a partner company between the years 2019 and 2022. The SAS program was used to analyze fixed effects and Pearson linear correlation. The components of variance for heritabilities were calculated using the MTDFREML program. MOD, MED, and MPD values of 29.94, 10.01, and 2.53 were obtained for Nellore and 30.12, 8.17, and 2.34 for Senepol, respectively. In general, Nellore provided better embryo production compared to Senepol. Heritability estimates showed low to medium magnitude, with values Nellore and Senepol of 0.16 and 0.04 (Pcleav), 0.14 and 0.08 (Pemb), 0.02 and 0.15 (Ppreg), 0.07 and 0.02 (MED), and 0.05 and 0.00 (MPD), respectively. However, it indicates the presence of genetic variability and the possibility of selection. Therefore, there is genetic variability for IVEP traits in both breeds, indicating that they can be used as selection criteria because they are heritable and that Nellore presents better performance for IVEP traits compared to Senepol.

Resumo O objetivo deste estudo foi avaliar os parâmetros hemato-bioquímicos do tambaqui Colossoma macropomum em diferentes fases de crescimento em cultivo integrado com açaí Euterpe oleracea. Para isso, 240 tambaquis juvenis, com peso e comprimento médio inicial de 21,8 ± 7,74 g e 11,28 ± 6,88 cm, foram cultivados em sistema aquapônico integrado ao açaí por 180 dias. No período, 107 tambaquis saudáveis foram amostrados e categorizados em cinco fases distintas de crescimento. Em cada fase de crescimento foram coletadas alíquotas de sangue para análises. A 1ª fase avaliou peixes com peso médio de 103,1 ± 5,27 g; a 2ª, peixes com 823,4 ± 42,6 g; a 3ª, peixes com 1.087,75 ± 16,38 g; a 4ª, peixes com 1402,0 ± 76,6 g e a 5ª, peixes com 1815,0 ± 65,1 g. As variáveis de qualidade da água permaneceram dentro dos parâmetros aceitáveis para ambas as culturas. Eritrócitos foram significativamente diminuídos na 1ª e 2ª fase. Hemoglobina foi significativamente diminuída na 1ª fase. O hematócrito manteve-se igual a partir da 2ª fase. O VCM foi significativamente inferior nos peixes com 1815,0 ± 65,1 g. Os níveis de glicose plasmática foram significativamente diminuídos na 1ª e 2ª fases. Colesterol, triglicerídeos e proteínas totais foram significativamente aumentados nos peixes na 5ª fase. AST foi significativamente diminuído nos peixes na 3ª fase, comparado com a 1ª e 5ª fases. ALT foi significativamente aumentado nos peixes na 1ª fase, comparado com a 3ª, 4ª e 5ª fases. Os resultados são ferramentas importantes para avaliar a saúde e o bem-estar do tambaqui em pesquisas futuras envolvendo culturas aquapônicas.

ABSTRACT Objective: To analyze the skin injuries of hospitalized newborns and identify factors related to the number of lesions. Method: This was a cross-sectional epidemiological study carried out over a period of one year in a Neonatal Intensive Care Unit in the west of Paraná. The study included 74 newborns with a score ≥5 on the Newborn Skin Condition Scale. Data analysis by chi-square and Pearson's test (p < 0.05). Results: The frequency was 25.4%, 59.4% had more than one lesion, mainly dermatitis and pressure injury. Birth characteristics were not related to the number of lesions. Not using antibiotics and parenteral nutrition, hemoglobin >11g/dl, phototherapy, pain score <4 and hospitalization >30 days were related to the number of lesions. The presence of two injuries led to longer healing time and three to longer hospitalization. A higher score on the Skin Condition Scale was related to healing time and late start of the diet. Conclusion: Skin injuries were found to be infrequent among newborns, but there is still a need to improve practices to prevent and maintain skin integrity.

RESUMO Objetivo: Analisar as lesões de pele de recém-nascidos hospitalizados e identificar fatores relacionados ao número de lesões. Método: Estudo epidemiológico seccional, realizado no período de um ano, em Unidade de Terapia Intensiva Neonatal do Oeste do Paraná. Foram incluídos 74 recém-nascidos com escore ≥5 na Escala de Condição da Pele do Recém-Nascido. Análise de dados por teste qui-quadrado e Pearson (p < 0,05). Resultados: A frequência foi de 25,4%, 59,4% apresentaram mais de uma lesão, principalmente dermatites e lesão por pressão. Características do nascimento não se relacionaram ao número de lesões. Não usar antibióticos e nutrição parenteral, hemoglobina >11g/dl, fototerapia, escore de dor <4 e hospitalização >30 dias foram relacionados ao número de lesões. Presença de duas lesões levou maior tempo de cicatrização e três, de hospitalização. Maior escore na Escala de Condição da Pele se relacionou ao tempo de cicatrização e início tardio da dieta. Conclusão: A lesão de pele mostrou-se pouco frequente entre os recém-nascidos, mesmo assim, é preciso aprimorar as práticas para prevenir e manter a integridade da pele.

RESUMO Objetivo: analisar a influência da cartilha “Como você pode contribuir para a segurança do bebê no hospital?”, em relação ao conhecimento e comportamento dos acompanhantes quanto às ações de segurança do neonato. Método: estudo quase experimental, do tipo antes e depois, foi desenvolvido com 60 acompanhantes de neonatos na unidade de cuidados intermediários neonatal de um hospital público, entre dezembro de 2022 e fevereiro de 2023. A coleta ocorreu por meio de dois grupos, controle e experimental, com o uso da cartilha e ocorreu em três fases: pré e pós-teste e intervenção. Para comparar os escores de pré e pós-teste foi utilizado o Teste de Kolmogorov-Smirnov e McNemar e o nível de significância adotado foi de α=0,05. Resultados: o grupo experimental apresentou um percentual maior de acertos no pós-teste após utilização da cartilha, evidenciando aumento do conhecimento e comportamento positivo nas ações de segurança. Entretanto, apenas os itens de conferência da pulseira e confirmação de seus dados antes do cuidado apresentaram significância estatística. Conclusão: a cartilha demonstrou ser uma ferramenta importante no processo de educação e saúde, o que pode ser favorável para a segurança do neonato.

ABSTRACT Objective: to adapt and evaluate the measurement properties of the Ostomy Self-Care Index in the Brazilian culture. Method: methodological study carried out in a public hospital in Campinas, Brazil. For cross-cultural adaptation, the following stages were followed: translation and synthesis; back-translation; evaluation of content validity; pre-testing and evaluation of the final version by the author of the original instrument. The Content Validity Index, Modified Kappa coefficient, and Content Validity Ratio were used for content validity. The evaluation of the measurement properties followed the recommendations of the Study Design checklist for Patient-reported outcome measurement instruments. Reliability was tested through internal consistency and construct validity through confirmatory factor analysis and the testing of three hypotheses. Six specialists and 160 patients participated in the study. Data collection took place between October 2020 and June 2022. Results: the stages of cross-cultural adaptation were carried out without difficulty. The internal consistency assessment obtained values within the established range. The confirmatory factor analysis of Sections A, B, and D of the OSCI (Brazilian version) showed satisfactory results after excluding two items. The hypothesis test partially corroborated one of the hypotheses and confirmed the other two. Section C could not be evaluated as it was intended only for patients with complications (n=66). Conclusion: Sections A, B, and D of the Brazilian version of the OSCI demonstrated evidence of structural construct validity and reliability and can be used in both clinical and scientific practice.

RESUMO Neste estudo, objetivou-se analisar a inclusão escolar de usuários de implante coclear. A pesquisa teve abordagem qualitativa, com desenho transversal e foi realizada em um hospital de alta complexidade em saúde auditiva credenciado ao Ministério da Saúde. A amostra foi por conveniência, constituída por implantados, com idades entre 4 e 17 anos e seus respectivos responsáveis legais. O fechamento amostral deu-se por saturação teórica com um total de 13 participantes. A participação no estudo foi voluntária e seguiu todas as normativas éticas vigentes. A coleta de dados foi realizada, inicialmente, por meio de caracterização sociodemográfica baseada nos prontuários e fichas sociais. Na sequência, foi realizada entrevista narrativa com os responsáveis, permitindo uma análise do corpus em profundidade. Os dados demonstraram situações vivenciadas pelos usuários de implante coclear no processo de inclusão escolar como: negativa de vagas; desconhecimento das equipes de educação; baixo desempenho; situação de bullying; preconceito; e falta de profissional para o atendimento educacional especializado. Os resultados apontaram que os usuários de implante coclear apresentam dificuldades no processo de inclusão escolar e que estas decorrem, principalmente, da falta de articulação das políticas públicas de saúde e educação no que concerne a essa população.
