Published: February 2024

Eficiência energética é uma importante questão que deve ser levada em consideração quando se estabelecem metas para promover o desenvolvimento sustentável de grandes cidades. Inúmeras políticas mundiais buscam cumprir objetivos sustentáveis por meio da eficiência energética, como a Agenda 2030, estabelecida pela ONU. Neste sentido, uma maneira de atingir esses objetivos é requalificar edificações já existentes nos grandes centros urbanos. Para isso, a elaboração de arquétipos de edifícios se mostra uma importante ferramenta, uma vez que permite avaliar o desempenho energético e calcular oportunidades de economia de energia através de simulações computacionais. Assim, o objetivo deste trabalho é identificar e analisar, através de revisão sistemática de literatura (RSL), os principais estudos relacionados ao desenvolvimento de arquétipos de edifícios, principalmente da tipologia comercial. Os estudos mais relevantes publicados de 2012 a 2023 foram selecionados através de pesquisa na base de dados Scopus. Os resultados apontaram o interesse crescente nesta temática, além de um predomínio de publicações em países do hemisfério Norte, destacando uma lacuna do conhecimento importante em relação a países de clima quente, como o Brasil. O desenvolvimento de arquétipos para edifícios comerciais compreendeu 24,5% da amostra e representou um número pequeno de publicações nos últimos dez anos, reforçando a importância de mais estudos a respeito do tema. Parâmetros relacionados a características físicas da edificação, como geometria, organização interna e percentual de abertura da fachada são geralmente consideradas no desenvolvimento destes modelos. Além disso, informações provenientes da legislação do local em estudo, sistemas de informação geográfica (GIS) e bases de dados variadas também são ferramentas amplamente utilizadas no processo. Busca-se com este trabalho fornecer uma base de conhecimento para trabalhos futuros e auxiliar pesquisadores na tomada de decisões.

Authors: Stjernswärd Sigrid , Meier Marie , Tilgmann Carola , Glasdam Stinne
Published: February 2024

This study focuses on children’s voices as they were presented in Swedish newspapers during the COVID-19 pandemic. It explores the ways in which journalists featured children’s experiences of everyday life during a time of crisis. A descriptive, thematic text analysis of 83 articles resulted in four prominent themes: children’s voices as a mouthpiece for or against school closure, children as cocreators of a new normal daily life, children as responsible and caring citizens, and COVID-19 as a magnifying glass for existing vulnerabilities in everyday life. The selection and representation of children’s viewpoints was adult led and limited, and the study thus calls for further research on media constructions of children/childhood and related consequences.

Analysis of the Evolution of Mathematical Models for Estimating Life Cycle of Power Substations
Authors: Ion Georgiana , Costinaș Sorina , Stan Andrei
Published: February 2024

The article analyses the evolution of mathematical models used in life cycle estimation. A comparison between the different mathematical models and their areas of applicability is proposed. This analysis is generally done in terms of costs. The importance of the article lies in the proposal of a new mathematical model for estimating life cycle of power substations, compatible with current and future requirements. The study findings reveal that an optimization model can be established using the life cycle assessment method to obtain a longer lifespan, but also to minimize costs (maintenance, repairs, replacements, etc.). In order to establish a mathematical model of the life cycle of electrical substations, it is necessary to study several important design parameters and decision factors for each stage of the life cycle. Even if the paper does not provide empirical results, it must prove that it is necessary to develop a multi-algorithm optimization framework to find an adequate solution. The life cycle must be modelled according to: equipment availability technological evolution, maintenance activities, risk management, environmental protection, human error, etc. The study helps further research to build, implement and validate a robust model with development possibilities depending on the needs of the researchers.

Published: February 2024

Innovation is one of the key competitiveness strategies for small, medium, and large companies. Production line innovations using Lean methods are currently one of the most important ways to change the shape of the production line in a positive direction. Emphasis must be placed on the resulting innovation and the form of the production line, which should be as efficient and functional as possible and meet the required parameters of productivity and quality assurance. The primary goal of production line innovations using Lean methods is the elimination of bottlenecks in the production process that do not add value and the balancing of individual assembly stations. The aim of the contribution was to design a semi-automatic line for the completion and testing of seat locks under the name D3P2. The result of the solution is the creation of a robotic workplace that will ensure a higher production capacity and the related packaging of finished products. On the assembly line, an analysis of line balancing was carried out using the Yamazumi graph to eliminate unnecessary assembly process activities, Cycle time and Tact time. An analysis of the measurements of individual production activities and places was carried out on the line, and the proposal for a new production line was subsequently shared. Its main goal was to meet all customer requirements through high flexibility. The result of the analysis and applied measures was a reduction in the cycle time of the new line, balancing of individual posts and economic benefits.

Authors: Istiqomah Dinnullah Riski Nur , Fitriani Rahma , Marjono Marjono
Published: February 2024

Motorcycle accidents in East Java are more common than accidents in other modes of transportation. In addition to the many motorcycle users today, human, environmental, and road factors are considered the highest causes of these accidents. The study's goal is to find the best model of the Generalized Poisson Family Distribution (GPR), namely Lagrangian Poisson Regression (LPR) and to construct a model that will quantify the frequency of motorcycle accidents in East Java. Akaike Information Criterion (AIC) and Schwarz Bayesian Criterion (SBC) criteria are the model comparison methods used in this research. The selection was also made based on the model's exponential coefficient with a 95% CI to further deepen the selection results obtained. In addition, the paired samples test was performed to determine the degree of dissimilarity between the outcomes produced by the developed model and the actual data. The best performance model is applied to identify the characteristics or factors highly involved in motorcycle accidents. The research uses secondary data from related agencies, namely the East Java Regional Police, especially the traffic accident unit, and East Java BPS, for 38 cities and districts in 2021. The numerical optimization method used is the iteratively reweighted least squares (IRLS) algorithm, assisted by R Studio software. The study findings show that LPR is the most efficient and exact approach for modeling the frequency of motorcycle accidents. Meanwhile, the percentage of teenagers (X1), the frequency of motorized vehicles (X3), and the average annual rainfall (X5) have a considerable impact on accident occurrence. This research has an important contribution, especially in the field of transportation modeling and designing appropriate strategies to reduce the frequency of motorcycle accidents.

Authors: Ducuara Manrique Alberto , Manrique Medina Alfonso , Vargas Ortiz Luz Elena
Published: February 2024

The main objective of this research is to develop a methodology to calculate a soil quality index in cocoa crops (Theobroma cacao L.), based on chemical properties such as pH, cation exchange capacity, organic matter, and percentage of base saturation, essential for the availability of nutrients in each cocoa tree. The problematic situation that causes this research is related to low yields per hectare, in small and medium-sized cocoa farms in the department of Huila – Colombia. A chemical quality index is proposed, which facilitates the analysis of the health behavior of the cultivated soil and nutrition of the cocoa plants, as a result of its interrelation with the physical and biological aspects. The proposed methodology is based on principal components analysis, to obtain weights and variable standardization equations, which evaluate 248 soil samples. The data indicate that in the cocoa producing land lots there are high pH values, cation exchange capacity and base saturation, but low levels of organic matter. It is concluded that in general the soils used showed moderate or low quality (52.42% and 11.29%, respectively), the rest showed high quality (36.29%). A soil intervention can improve its quality, however, the characteristic of the crop and the low levels of organic matter, requires recovering the properties and improving the health of the soil, if possible, through the implementation of regenerative agriculture, the object of future studies and research.

Understanding the margin of error (MoE) as a part of statistical literacy which is useful for the public to select credible information from various surveys and polls. The study aims to reveal the levels of statistical literacy of mathematics education students, especially in understanding MoE, and compare them based on four variables: gender, enrollment in a statistics course, year in the program, and type of university. The online survey research involved undergraduate students of the mathematics education study program from 21 universities in Indonesia’s western, central, and eastern regions as the sample (n = 970). Descriptive statistics was used to describe the literacy levels and inferential statistics (t-test and F-test) to compare them based on the four variables. The results of the study reveal that: (1) student literacy in understanding the MoE concept is dominant at the non-literate level; and (2) there are significant differences in students’ literacy levels in terms of gender, enrollment in a statistics course, year in the program, and type of university. The study indicates that the literacy of mathematics education students is still low, so the statistics course is expected to focus more on developing statistical literacy.

Authors: Sherifi Idaver , Lebid Olesia , Goncharova Olga , Drobyazko Svetlana , Sidko Inna
Published: February 2024

Bitcoin is an asset with high risks, and a significant part of its volatility can be explained by the speculative component. Parametric variance-covariance (VaR) methods are not applicable for assessing the risks of bitcoin investment, since log returns are not distributed according to the normal law. Autoregressive risk assessment models (such as ARIMA-GARCH) for bitcoin volatility overestimate risks at times of sharp exchange rate changes and they underestimate them at times of less significant rate changes compared to historical volatility. The grid search for the smoothing parameter in the exponentially weighted moving average method is potentially interesting for modeling the risks of bitcoin investment. This makes it possible to fully take into account the autocorrelation of the bitcoin rate to the levels of previous periods and the volatility of the asset. As a conclusion, there are currently no econometric models that can explain and forecast the volatility of bitcoin in the medium and short term, considering the available factors in the market.

Authors: Ngoc Thuy Doan Thi , Huu Hao Nguyen , Minh Tuan Phan , Lam Thinh Do Huynh , Van Dung Nguyen
Published: February 2024

Job satisfaction is an important factor in promoting an employee’s well-being, productivity, and organizational success. Generally, when job satisfaction is high, employees experience greater emotions of fulfillment, motivation, and engagement. This can result in increased productivity, improved performance, and a decrease in employee turnover rates. Low job satisfaction, on the other hand, can result in tension, exhaustion, and a diminished sense of accomplishment and job security. It can also have negative effects on a person's physical and mental health and lead to decreased productivity, increased absenteeism, and increased turnover rates. Therefore, it is interesting to study some factors behind job satisfaction, especially in the context of a developing country. In particular, this study examines the roles of organizational commitment, supervisory emotional support, and training in job satisfaction. Furthermore, this research also investigates the moderating impact of training on the organizational commitment-job satisfaction relationship. The research collected data on office employees in Vietnam from December 2022 to January 2023. The quantitative analysis was conducted using SPSS and AMOS software. The findings reveal that organizational commitment, supervisory emotional support, and training have positive influences on job satisfaction. Additionally, training has a positive moderating role in the organizational commitment -job satisfaction nexus. The practical implications emphasize that organizations should create a supportive work environment and encourage emotional support from managers. Moreover, companies should prioritize training opportunities for staff members to improve their work satisfaction.
AUTOGOVERNO INDÍGENA: UM ESTUDO COMPARADO ENTRE BRASIL E BOLÍVIA
Authors: Gurgel de Brito Lauro , Alves da Silva Hanieri
Published: February 2024

O objetivo deste trabalho é investigar se a Constituição de 1988 garante a prerrogativa do autogoverno às comunidades indígenas, segundo os cânones do novo constitucionalismo latino-americano presentes na Constituição da Bolívia. A investigação foi conduzida por método dedutivo e comparativo, análise documental e bibliográfica, estatística descritiva para análises comparativas. Os resultados mostram que, na comparação entre os modelos constitucionais do Brasil e da Bolívia, é possível notar que, naquele, o paradigma ocidental eurocentrista afirma a soberania constitucional e um sistema mono jurídico (hegemônico) do Direito. Já o arquétipo boliviano se propõe a efetivar o autogoverno e a autodeterminação dos povos originários campesinos. O paradigma brasileiro promove uma política anti-indígena, em prol de um modelo econômico capitalista, a exigir formas alternativas de interpretar a Constituição e identificar instrumentos que garantam a autodeterminação e autonomia dos povos originários no Brasil.

Authors: Ravnjak David , Čepon Gregor , Mihelič Aleš , Frangež Tina , Elomari Jawad
Published: February 2024

Due to high demand and increasing prices of wood-based cellulose, alternative sources of lignocellulosic biomass are gaining on their importance. Among them are invasive alien plants (IAP) that currently are being discarded (burned or composted) in spite the fact that they can be converted to useful products. For packaging of large home appliances, currently expanded polystyrene (EPS) is used. By exchanging EPS with cellulose-based (from IAP biomass) packaging, the circular nature of the packaging will be improved. Within the first stage of the LEAP project the potential of IAP biomass for conversion to cellulose and its use for production of foam formed packaging materials is being studied – various IAP have been evaluated in terms of their potential use for cellulose production, cellulose quality and key mechanical parameters. The data gathered is being used in computer assisted design and construction of packaging for large home appliances. A preliminary LCA analysis on the use of alternative raw materials as a source for cellulose production has also been performed.

Published: February 2024

Many species of marine mammals are threatened and their populations decline worldwide due to the increase of anthropogenic activities such as fishing, shipping, pollution and climate change. Our understanding of marine mammal behavior/ecology remains poor and under-documented since studies of the kind are extremely challenging in practice and theory. Applied anthropology can help provide effective strategies based on cultural compatibility. Marine biology has already validated that biodiversity is beneficial to the ecosystem and so should anthropology promote the significance of mutualism in society.

Authors: Sinitsyn M. , Popadko A.
Published: February 2024

Low-emission nuclear power industry is called upon to play an important role in the development of the global energy industry and contribute to the solution of the problem of decarbonization of economic growth. For countries betting on the development of nuclear energy, a critical issue is the sustainability of nuclear fuel supplies in the medium and long term. The countries of Central Asia, primarily Kazakhstan and, to a lesser extent, Uzbekistan, have significant resource of natural uranium and are geographically close to large consumers of nuclear fuel in Europe and the Asia-Pacific region. Both countries plan to reach carbon neutrality: Kazakhstan – by 2060, Uzbekistan – by 2050, which may be achieved through the construction of nuclear power plants. The article considers the strategy for the development of the uranium complex in both countries, the core of which is the wide access of foreign investors to the development of uranium reserves in exchange for access to export markets and modern technologies. The achievements of Kazakhstan in increasing uranium production, the barriers to the development of the national state company Kazatomprom upward the technological chain, the prospects for nuclear energy in Kazakhstan and Uzbekistan are analyzed. It is concluded that the current energy crisis enhances the global interest to the development of nuclear generation, but also emphasizes the importance of an adequate assessment of the availability of uranium reserves and the prospects for diversifying its supplies to the world market.

Poland’s Eastern Policy: Conceptual Foundations and Practical Aspects
Authors: Ofitserov-Bel'skiy D.
Published: February 2024

The article examines Poland’s Eastern policy and its conceptual foundations. Particular attention is paid to the “Promethean concept” and the Giedroyc-Mieroszewski doctrine. It is concluded that these concepts represent part of the multidimensional construction of the self-myth. The relationships with Russia are at the heart of these concepts, through them the representation of Polish history, society and statehood takes place, and Polish identity is formed. At the same time, relations with Russia and in the post-Soviet space as a whole didn’t become a field of development of interests for Poland. Poland doesn’t have sufficient resources for a foreign policy that could correspond to the declared concepts. For this reason, Polish diplomacy in its Eastern policy prefers collective action and performs primarily agent functions.

Objectives. Due to the rarity of olfactory neuroblastoma (ONB), there is ongoing debate about optimal treatment strategies, especially for early-stage or locally advanced cases. Therefore, our study aimed to explore experiences from multiple centers to identify factors that influence the oncological outcomes of ONB.Methods. We retrospectively analyzed 195 ONB patients treated at nine tertiary hospitals in South Korea between December 1992 and December 2019. Kaplan-Meier survival analysis was used to evaluate oncological outcomes, and a Cox proportional hazards regression model was employed to analyze prognostic factors for survival outcomes. Furthermore, we conducted 1:1 nearest-neighbor matching to investigate differences in clinical outcomes according to the use of neoadjuvant chemotherapy.Results. In our cohort, the 5-year overall survival (OS) rate was 78.6%, and the 5-year disease-free survival (DFS) rate was 62.4%. The Cox proportional hazards model revealed that the modified Kadish (mKadish) stage and Dulguerov T status were significantly associated with DFS, while the mKadish stage and Hyams grade were identified as prognostic factors for OS. The subgroup analyses indicated a trend toward improved 5-year DFS with dural resection in mKadish A and B cases, even though the result was statistically insignificant. Induction chemotherapy did not provide a survival benefit in this study after matching for the mKadish stage and nodal status.Conclusion. Clinical staging and pathologic grading are important prognostic factors in ONB. Dural resection in mKadish A and B did not show a significant survival benefit. Similarly, induction chemotherapy also did not show a survival benefit, even after stage matching.

Published: February 2024

En la presente revisión bibliográfica se define y caracteriza a los plaguicidas, con el fin de poder definir y clasificar al Clorpirifos. La caracterización de los plaguicidas se da de acuerdo a su composición, por su grupo de acción, por su persistencia y su toxicidad, en el caso del Clorpirifos este se clasifica como un insecticida organofosforado considerado como moderadamente tóxico y su persistencia en el suelo varía desde cinco días a veinte años. Se ha evidenciado que el insecticida Clorpirifos no sólo actúa sobre su grupo de acción, sino que involucra a los organismos de su entorno afectándolos de manera significativa. Además de evidenciarse la persistencia de este insecticida en el suelo, afectando no sólo a los organismos que lo habitan, sino que también se han evidenciado en productos alimentarios, esto interviene en la cadena trófica y conlleva a la intoxicación de los humanos. La aplicación de insecticidas ha causado que los organismos se vuelvan resistentes, por lo cual se aplican dosis más altas de este insumo químico o el uso de insecticidas más tóxicos para poder controlar a las plagas. Para poder determinar la condición en la que encontramos el suelo referente a su salud y fertilidad, es necesario analizar parámetros fisicoquímicos y biológicos, como lo son el pH, la conductividad eléctrica, el contenido de materia orgánica, textura y la biomasa del suelo (micro y macrofauna). Por todo lo expresado es importante la regulación del uso estos insumos químicos, por lo cual se presenta la normativa nacional e internacional aplicada.

In this study, periodic mesoporous organosilica (PMO)/ZnO nanocomposites were synthesized and investigated as a delivery system for the anticancer drug (gemcitabine). Rice bran extract was used for the green synthesis of ZnO nanoparticles. According to the characteristic results, by increasing the amount of ZnO, the size of the spherical particles increased and surface area and pore volume decreased. Between the two nanocomposites, the maximum gemcitabine loading content (53.1%) is related to the sample with the lowest concentration of ZnO nanoparticles. For all samples, the gemcitabine release at pH=5.6 is greater than pH=7.4. The rate of gemcitabine release was fast in the first 8 hours and decreased over time.

Endocrine disrupting contaminants (EDCs) are frequently monitored in environments because of their biological impacts on wildlife and humans. We conducted a systematic review using Web of Science to identify global research trends in abiotic and biotic EDC environmental sampling. Specifically, we aim to better understand geographic variation in 1) the compartment that EDCs were sampled in the environment; 2) the types of EDC sampled; and 3) the taxa that are sampled. A total of 9,140 papers were found in our search, of which 2,554 were included in our review. The number of studies sampling environmental EDCs varied between continents, with the majority of research occurring in Europe, Asia, and North America. Across all continents, water was the most frequently sampled compartment to determine environmental EDC concentrations, and was sampled in 50–75% of studies across continents. Wildlife were sampled far less often in studies across all continents, and comprised of 30% of studies at most. Pharmaceuticals were the most-commonly studied chemical group, and fish were the most-commonly sampled taxonomic group. Although far fewer studies sampled for EDC’s in wildlife compared with abiotic compartments (i.e. water). These studies provide valuable information on the potential consequences of environmental EDC exposure and link environmental surveillance of EDCs with lab-measured organism-level effects. Studies that sampled only the water matrix for EDCs may be doing so as a proxy despite the large knowledge gaps on how environmental EDCs affect wildlife at varying concentrations.
Three-stage location-routing programming for heavy-duty railway maintenance machinery maintenance base based on multi-factor combined weights

An imperative shift towards a scientific and methodical approach has become increasingly essential when deliberating the placement of maintenance bases for robust railway machinery dedicated to heavy-duty tasks. This article addresses the need for a systematic approach to placing maintenance bases for robust heavy-duty railway machinery. It introduces a meticulously crafted three-stage location-routing paradigm that factors in both qualitative and quantitative determinants. This approach optimizes routing strategies for the machinery while constructing an evaluative framework for base placement. An evaluative index is created by merging relevant qualitative and quantitative elements, using an enhanced game theory methodology combined with the evidential analytic hierarchy process and the entropy weight method to balance subjective and objective considerations. The model’s complexity is handled with an improved genetic algorithm and a hybrid ant colony algorithm, effectively addressing location and routing interactions. Practical implementation and case studies validate the model’s and algorithm’s efficacy, confirming their applicability in real-world scenarios.

The study aimed to assess the effect of High-Intensity Focused Electromagnetic (HIFEM) technology in treating female stress urinary incontinence (SUI). Twenty women with SUI were delivered a treatment course with HIFEM technology. Patients attended six therapies scheduled twice a week. Urodynamic exams, pad tests, and validated questionnaires were assessed, including OABSS, UDI-6, IIQ-7, ICI-Q, and vaginal laxity questionnaire. We also evaluated the bladder neck mobility in ultrasound topography pre- and post-treatment at 1- and 6-month follow-up visits. As for the results, HIFEM treatment significantly improved SUI symptoms on pad tests and patients’ self-assessments in the 6-month follow-up. Besides, the data from urinary-related questionnaires all showed a significant reduction. The analysis of the urodynamic study revealed that only maximum urethral closure pressure and urethral closure area significantly increased after the six sessions of HIFEM treatment. The urethral and vaginal topography was examined, and found that HIFEM mainly worked on pelvic floor muscle and enhanced its function and integrity. In conclusion, HIFEM technology is an efficacious therapy for treating SUI.

In response to the problem of poor flexibility of common one-dimensional flexible conductors at low temperatures, this paper proposed a one-dimensional flexible conductive composite material with cotton fiber as the substrate and silver-nanowires as the conductive fillers to meet the demands of flexible conductors in low temperature fields such as space exploration, superconductivity, low-temperature biology, etc.Through a creative "bottom-up" fabricating process, by adjusting the amount of filler added and the degree of intertwining between cotton fibers, 1D flexible conductor with good flexibility, conductivity, strength and stability is obtained. After 10,000 times of flexibility tests at liquid nitrogen temperature (77K), the resistance change of the 1D conductor is less than ±0.5%, showing excellent flexibility and stability of the material at low temperature environment. A demonstration was then successfully conducted by connecting the 1D conductor to the circuit as the flexible part of the system in simulated working environment (77K). The system worked well with good stability under repeated bending of the mechanical arm, demonstrating high applying potential of the 1D conductor in the field of low-temperature flexible conductive materials.
