Authors: Owolabi Oluwafemi Collins , Adanlawo Eyitayo Francis , Owolabi Abimbola Gbemisola
Published: August 2024

Objective: Literature has attributed low responsiveness to poor incentive, lack of motivation, and ‘red tapism’, while attitudinal predisposing factors remain under-researched among nurses in public health institution. Therefore, this study investigated how job involvement, work Satisfaction, age, and sex predicted responsiveness behaviour among nurses.
Methods: The study was a cross-sectional survey in which 68 nurses comprising 25 males and 43 females purposively selected were sampled. Participants were drawn from among Nurses in Abua Multi-System Hospital, Ado-Ekiti, Ekiti State, using simple random sampling technique. A structured questionnaire divided into four sections and contained standardized scales that measured responsiveness, job involvement, and work Satisfaction was the instrument used for data collection. The scales were revalidated during pilot study to ascertain their reliability and suitability for use within the Nigerian cultural context. They all yielded high Cronbach alpha coefficients. Three hypotheses were tested in the study. Data were analyzed with multiple regression and t-test analysis at 0.05 level of significance.
Results and discussion: Results showed significant joint influence of work Satisfaction and job involvement on empathic behavior, F (2,68) = 12.68; p<.01); female nurses were significantly higher on empathic behavior than male nurses t (68) = -2.40; p< .05; and younger nurses displayed higher level of responsiveness than older nurses, t (234) = 12.15; p<.01.

Authors: Cacheado Marco Aurélio Andrade , Rodrigues Isabel Cristina Braga , Nucci Edson Romano
Published: August 2024

Objective: The objective of this study was to apply Artificial Neural Networks to evaluate the performance of Microbial Energy Cells, to identify the best network configuration for cell evaluation.
 
Theoretical Framework: Although several of the widely used effluent treatment methods show results, most of them have a common disadvantage: they lose the chemical energy contained in the treated effluent and have high energy consumption for their conduction. Therefore, an increasing effort has been made to develop effluent treatment technologies capable of recovering part of the energy contained in the waste to be treated. In this scenario, microbial energy cells (CEM) emerge as a potential technology, as they are devices that simultaneously treat effluent biologically and generate electrical energy.
 
Methodology: For the application and evaluation of ANNs in CEM, a feedforward neural network was used, with a Levenberg-Marquardt training algorithm, 1 or 2 hidden layers, with sigmoid and tansig activation functions, and an accuracy factor of 10-5. The data used for training and validation for the ANN were obtained through a literature search. Networks with 15, 30, 50, 90, 100, 130, 150, and 200 neurons were used for testing to evaluate the best performance.
 
Results and Discussion: With the results obtained, it was observed that the best adjustment of the network occurred with the 2-layer configuration, one layer with 100 neurons and the other output layer, with 49 interactions and R2 of 0.91 in the training adjustment, 0 .78 in the validation fit and 0.90 in the fit with all experimental data evaluated, respectively.
 
Originality/Value: This study contributes to the literature by evaluating the application of artificial neural networks, which are empirical modeling mechanisms, inspired by biological nervous systems, with processing abilities, in microbial energy cells.

Authors: Pitono Andi , Sutiyo  , Baidhowah Adfin Rochmad
Published: August 2024

Objectives: This study aimed to analyze the tenurial system of customary land in Java, its deficiency, the accompanying consequences on land access, and the identification of modes of improvement in order to accelerate rural development.   Theoretical framework: This study was based on theories of rural development and decentralization, with a specific focus on landless farmers.   Method: This study employed qualitative method to analyze the tenurial system of customary land in Java. Data were collected through two steps, first, observations, interviews, and documentaries were conducted to understand the realities of customary land tenure from the descriptive statistics and narratives of local officers. Second, a focus group discussion involving local officers and villagers was held to present the initial findings, formulate a new tenancy system, and analyze the possibilities of its application in village administration.   Results and conclusion: Based on the villages in the Grobogan District of Central Java Province, this study showed that land use causes unequal access to landless farmers. The land management methods to finance village development programs are currently irrelevant in the framework of recent decentralization. A system that can benefit landless farmers is contract farming.   Implications of research: This study provided evidence-based information for policymakers to improve the use of customary land for landless farmers and an additional reference for rural development in the world.   Originality/value: Studies on Indonesian rural development have shown the strategic position of customary lands in Indonesia, especially in Java. However, little is known about the potential of customary lands to achieve sustainable rural development, as this issue is still inadequately addressed in the literature. This led to the implementation of this study, with the objectives of analyzing the tenurial system of customary land in Java, its deficiency, and accompanying consequences on land access, alongside identifying improvement approaches in order to accelerate rural development.

Authors: Horta Ricardo Augusto dos Santos , Lima Weslley Eunathan Fernandes , Pacheco Tiago de Sousa , Villela Luciana Silva
Published: August 2024

Objective: This work aims to analyze a sample of the mineral Rutana, composed of two crystalline phases of titanium dioxide (TiO2): rutile and anatase, using the X-ray diffraction technique.
 
Theoretical reference: In 1914, the German physicist Max von Laue, using a CaSO4 crystal, successfully achieved the diffraction of X-rays. Crystalline solids, such as CaSO4, consist of regular arrangements of atoms with interatomic spacings of the order of 0.1 -1.0Å, that is, with the same order of magnitude as the wavelength of X-rays. Due to the periodic nature of the internal structure of the crystals, it was possible for them to act as a three-dimensional diffraction grating, providing science with a new method for indirect investigation of the internal structure of materials: the X-ray diffraction (XRD) technique.
 
Methodology: In this technique, a finely ground crystalline powder of a material is placed in the path of a monochromatic x-ray beam. This material, composed of a large number of small crystallites, are randomly oriented. Diffraction occurs from planes of the crystallites that are oriented at the correct angle to fulfill the Bragg condition, in such a way that localized peaks of the same intensity as the diffracted beams are formed.
 
Results and discussion: Based on the intensity, angles and width of the diffraction peaks, the mass percentages of each of the mineral's crystalline phases were obtained: rutile (62.08%) and anatase (37.92%).
 
Research Implications: This work presents a contribution to future research related to the chemical characterization of initially unknown samples, by providing a comprehensive and representative theoretical framework related to the XRD technique.
 
Originality/value: This study presents practical contributions to the literature related to the application of the XRD technique in the characterization of materials.
Analysis of The Efficiency of Public Expenditure on Education in Elementary Education in The State of Alagoas
Authors: Andrade Daniel Mendes de , Souza Júnior Celso Vila Nova de , Moreira Tito Belchior Silva , Constantino Michel
Published: August 2024

Objective: This article analyzes the efficiency of public spending on education in the municipal public network in elementary education, in all cities in Alagoas, using the data envelopment analysis method, DEA.
 
Theoretical Framework: The present work used the variable return to scale (BCC) model, since we would be dealing with municipalities with varied realities. There are two basic ways for a unit that is inefficient to become efficient. The first would be to reduce resources (inputs) and keep products constant, which would be an input-oriented orientation; the second would be doing the opposite, increasing the result (products) from the same amount of inputs, an orientation focused on outputs.
 
Method: The data envelopment analysis method - DEA is used to estimate efficiency with traditional inputs such as school infrastructure, capital, labor and municipal wealth. As output, the Portuguese and mathematics grades in the 9th grade, in the Saeb 2019 test, are considered, multiplied by the students enrolled in this year of education; as well as the inverse of per capita expenditure on elementary education.
 
Results and Discussion: It was concluded that most of the benchmarkings are represented by municipalities with smaller inhabitants, indicating that the population increase in municipalities increases the demand for education.
Research Implications: Thus, based on technical efficiency analyses, public policies can be proposed that mitigate the deficiencies presented in elementary education.
 
Originality/Value: This study contributes to the literature by estimating the efficiency of municipalities in terms of public spending on education and the efficiency results are the grades of public school students. The research introduces a new output to measure efficiency, and points to new evidence for public educational policies.

Authors: Barbosa Júnior Raimundo Nonato da Silva , Andrade Eloisa Helena de Aguiar , Silva José Rogério de Araújo , Gonçalves José Francisco de Carvalho , Santos Alberdan Silva
Published: August 2024

Objective: The objective of this study is to describe the lipidomic profile of andiroba oil and its socio-economic characteristics focused on the activities of limonoids as an alternative for the generation of nonsteroidal anti- inflammatory drugs in order to relate the generation of products that act on circular and external peripheral inflammation.
 
Theoretical Reference: In this context, andiroba oil (C. guianensis) has a wealth of lipid substances with chemical and socio-economic potential, highlighting its importance for local populations and its potential for sustainable bioeconomics, as this species contains nonsteroidal antiinflammatory drugs from Amazonian oil plants.
 
Method: The methodology adopted includes  describing the lipidomic profile of andiroba oil analyzed by GC/MS, using a Zebrom 5HT capillary column specifically designed to analyze both the methyl esters of the various fatty acids and the limonoids and steroids. The bibliographic search was carried out in the CAPES periodicals on the Scopus database, using specific keywords such as andiroba, Carapa, limonoids and antiinflammatories. Three samples of andiroba oil collected in different states were used to compare the lipidomic profiles.
 
Results and Discussion: The results obtained revealed the presence of limonoids 7-desacetyl-7-oxogedunin, 7- oxogedunin, deacetyl gedunin; steroids campesterol, stigmasterol, b-sitosterol and various medium and long chain fatty acids. These results showed valuable information about the presence of limonoids, which have anti-inflammatory properties related to the chemical composition, which can vary with the season, the place of collection and the differences in the extraction processes of this oil. However, there is no total absence of limonoids.
 
Research Implications: This research's practical and theoretical implications emphasize that the active anti-inflammatory principles are found in the unsaponifiable fraction, and therefore, only lipidomic techniques can access these metabolites with more excellent resolution. Thus, with the structural identifications, in silico studies can be carried out to classify their effects on cyclooxygenase enzymes (COXs), specifically COX-1, in circular and external peripheral inflammation.
 
Originality/Value: This study contributes to the literature through the perspective of developing safe anti- inflammatory agents produced from andiroba oil, which is a source of great interest for topical use. This oil stands  out as one of the most scientifically studied natural products, being biocompatible and presenting itself as an economical and safe alternative for treating circular and external peripheral inflammations. The relevance and value of this research is evidenced by the fact that limonoids are inhibitors of cyclooxygenases, highlighting the prospect of a new socio-economic aspect.

Objective: The objective of this study aims to reflect on an organized set of synergies that contribute to an effective artistic-environmental dialogue: the aim of this interdisciplinary dialogue is to promote a balanced, conscious and informed plan of environmental education, mediated by art. In this specific case, the promotion of artistic and cultural events becomes a subsidiary of agents' ecological awareness and consequently acts as a force capable of mobilizing and raising awareness among current and future generations of the central causes and issues of contemporary society, precisely, those that relate to the “common home”.
 
Theoretical Framework: We have put together a tripartite theoretical framework in which ethical, aesthetic and artistic issues are related from a dialogical perspective between art and the environment and their respective impacts in terms of intervention in the community and with the community.
 
Method: Narrative literature review, seeking to describe or discuss the current state of the research topic and, in particular, to draw conclusions for the results and discussion of the effects and impacts of the practices resulting from this initiative that covers a significant and broad generational framework (from early childhood to old age), applying the same model and method. In this case, the MILMESA Method and the DEP Model.
 
Results and Discussion: The main results emerge as the conclusion of a concrete analysis of the reality observed and the theoretical matrices that underpinned the model and method used. These results are important for future reflection, in terms of what is meant by future adjustments to the results obtained in this research context.
 
Implications of the research: In the future, there are certain considerations that can be reflected on and improved, based on the structure and conceptual basis emanating from the reference authors (and works) that deal with the subject under debate and intergenerational reflection.
 
Originality/Value: This research promotes, in a unique way, a reflection on the making of technical-scientific, participatory and interdisciplinary events, which are in great demand at an educational and scientific level, in which art and art education emerge as a dialogue between areas and as an added value in the framework of the methodologies used in this type of initiative. The aim is to align research and artistic work (and related works) and, at the same time, to reflect on the practices and projects carried out in this field with scientific and training institutions in general, including institutions with more plural and diverse missions in terms of formal, non-formal and informal education.

Objective: The objective of this study is, based on the notions of practice and practical sense of Bourdieu (2009, 2011b), to analyze how the daily work of four elementary school teachers and their routines unfold.
 
Methodological procedures: This is an empirical sociological research in which data were collected through semi-structured interviews.
 
Theoretical framework: For Bourdieu, habitus produces practices and presents itself as a kind of practical sense, that is, the understanding of what should be done in a given situation.
 
Results and discussion: The four interviewed teachers have little time and resources to expand their cultural capital. Their routines are marked by practical sense in the classroom, that is, by moments in which the teachers' performance is marked by the automatisms of action.
Time-Varying Aeroelastic Modeling and Analysis for a Morphing Wing

Published: August 2024

The paper presents a novel time-varying aeroelastic modeling approach for the morphing wing with the process of camber changing. The time-varying modeling methodology includes structural dynamics modeling, unsteady aerodynamic modeling, and interpolation for fluid–structure coupling. Firstly, the morphing wing is modularized and divided into fixed and variable parts by the floating frame of reference formulation. It is combined with the Craig–Bampton method to reduce order and eliminate nonindependent degrees of freedom. Then, the unsteady vortex-lattice method is used to calculate the transient, unsteady aerodynamic force for time evolution. Furthermore, the above time-varying structural dynamics modeling and a fluid–structure coupling interpolation are integrated to construct overall aeroelastic modeling, obtaining a set of differential-algebraic equations. Finally, these equations are numerically solved by the [Formula: see text] method. The proposed approach provides an innovative idea to deal with the incredible complexity of the aeroelastic effect as structural characteristics change over time. It can efficiently and accurately analyze the morphing wing’s transient response or flutter property. To verify and utilize the time-varying aeroelastic modeling approach, numerical calculations and comparative studies were carried out regarding the time-varying characteristics of the structural modes, aerodynamic calculations, and flutter prediction of the morphing wing.

Various types of sensors are needed to monitor the health state of smart deep-space habitats. However, measured data can be affected by sensor faults, which influence the health management system and consequently the decision-making. In this paper, an unsupervised learning approach based on convolutional autoencoders (CAEs) is developed to detect anomalies in temperature and pressure sensors. The proposed method is systematically investigated using a habitat simulator (HabSim). Several illustrative examples are demonstrated in the nominal and hazardous states of the habitat, including micrometeorite impact and fire scenarios. The performance of the proposed method using CAEs is compared with that of existing methods using auto-associative neural networks (AANNs) and variational autoencoders. This comparison is based on typical evaluation metrics, including precision, recall, F1 score, training time, and testing time. The effect of temperature–pressure coupling on the detection performance of CAEs and AANNs is explored by training different data-driven models, including one with temperature sensors, one with pressure sensors, and one with both temperature and pressure sensors. The effect of the number of faulty sensors on the performance of CAEs is studied, as with an increase in the number of faulty sensors, redundant information among the sensors is reduced. The capability of CAEs to change the number of sensors without redesigning the network architecture and retraining the neural network is investigated and demonstrated. The capabilities and limitations of the proposed solution are discussed.
Benchmarking of Aerodynamic Models for Isolated Propellers Operating at Positive and Negative Thrust

Published: August 2024

Operating a conventional propeller at negative thrust results in the operation of positively cambered blade sections at negative angles of attack, leading to flow separation. Consequently, accurately simulating the aerodynamics of propellers operating at negative thrust poses a greater challenge than at positive thrust. This study offers a comprehensive assessment of the aerodynamic modeling capabilities of numerical methods, spanning low to high fidelity, for computing propeller performance across both positive and negative thrust regimes. Low-fidelity methods, namely, blade-element momentum and lifting line theories, effectively predict propeller performance trends at positive thrust. However, they fail to capture trends at negative thrust beyond the maximum power output point due to the neglect of three-dimensional flow effects. Both steady and unsteady Reynolds-averaged Navier–Stokes (RANS) simulations with [Formula: see text] perform well across both positive and negative thrust conditions, with errors below 2% for both thrust and power magnitudes near the maximum power output point. Lattice-Boltzmann very-large-eddy simulations (LB-VLESs) with [Formula: see text] exhibit excellent agreement with experimental data with less than 1% error near the maximum power output point but with significant computational costs. Conversely, LB-VLESs with [Formula: see text] offer a more economical approach to capture general trends with the computational cost of the same order as unsteady RANS. However, wall models introduce errors in modeling flow separation, leading to a 16% overestimation of power magnitude near the maximum power output point. The results highlight the necessity of using tools with increased fidelity levels when considering propeller operation at negative thrust compared to the conventional positive thrust regime.
