Published: November 2024

This study aims to investigate the impact of dance training on the mental health of college students. Utilizing experimental research methods, we established an experimental group and a control group to compare changes in mental health dimensions—including anxiety, depression, self-esteem, and social skills—between the two groups before and after 12 weeks of dance training. The findings indicate that dance training significantly reduces levels of anxiety and depression, while also improving self-esteem and social skills, thereby enhancing social adaptability. These results provide empirical support for the use of dance as an intervention for mental health and offer new insights for mental health education in colleges and universities.

Published: November 2024

This study analyzes the social and individual stigmatization toward Venezuelan immigrants in Peru within the context of the largest migratory movement in Latin America, driven by the political, economic, and humanitarian crisis in Venezuela. The study employs a qualitative approach, using semi-structured in-depth interviews with a diverse sample of 24 participants from major Peruvian cities, including Lima, Arequipa, Cusco, and Trujillo. These in-depth interviews provide insights into the complexity of perceptions toward Venezuelan migrants, ranging from stigmatizing views driven by associations with economic threats and criminality to more positive perceptions that acknowledge the migrants’ adaptability and economic contributions. The findings reveal that while negative stereotypes perpetuate social exclusion and pressures for cultural assimilation threaten the preservation of migrant identities, there are also narratives highlighting resilience and successful integration. The study emphasizes the importance of implementing intercultural education programs, promoting labor integration policies, and collaborating with the media to combat stigma. It concludes that addressing these challenges through a multidimensional, human-rights-based approach can foster greater social cohesion and better integration of migrants, benefiting both the migrant population and Peruvian society.
Role of livelihood capitals and sustainability on the access to provisioning services: A case study of Gosaba block of Sundarban, India
Authors: Das Semanti , Das Chandan Surabhi
Published: November 2024

In marginalized ecosystem-dependent rural communities, access to ecosystem services plays a crucial role in achieving sustainable livelihoods. This study was conducted to find out the influence of various livelihood capital components on the access mechanism for forest-based Provisioning Services (PS) in some selected villages of the Gosaba Block on the fringes of the Sundarban. The contribution of the livelihood capitals to gain access to Provisioning Services (PS) was identified using factor analysis on 160 households, selected through cluster random sampling. The sustainability levels of livelihood capitals were analyzed using the Prescott-Allen method (2001). The natural, financial, social, and physical capitals were significantly below average, while the human capital was close to average. Enhancement of human, physical, financial, and social capital, ease in issuing Biometric Fisherman cards for entering forests, flexibility in borrowing loans, and ecotourism by involving local villagers must be encouraged to enhance forest-based provisioning services in the near future.

Published: November 2024

Himalayan ‘Ecotone’ temperate conifer forest is the cradle of life for human survival and wildlife existence. Human intervention and climate change are rapidly degrading and declining this transitional zone. This study aimed to quantify the floristic structure, important value index (IVI), topographic and edaphic variables between 2019 and 2020 utilizing circular quadrant method (10m × 10m). The upper-storey layer consisted of 17 tree species from 12 families and 9 orders. Middle-storey shrubs comprise 23 species representing 14 families and 12 orders. A total of 43 species of herbs, grasses, and ferns were identified from the ground-storey layer, representing 25 families and 21 orders. Upper-storey vegetation structure was dominated by Pinus roxburghii (22.45%), while middle-storey vegetation structure was dominated by Dodonaea viscosa (7.69%). However, the ground layer vegetation was diverse in species composition and distribution. By using Ward’s agglomerative clustering technique, the floral vegetation structure was divided into three floral communities. Ailanthus altissima, Pinus wallichiana, and P. roxburghii had the highest IVI values in Piro–Aial (Group 2), Piwa–Quin (Group 3) and Aial–Qugal (Group 2). The IVI values for Aesculus indica, Celtis australis, and Quercus incana in Aial-Qugal (Group 2) were not determined. Nevertheless, eleven of these species had 0 IVI values in Piro–Aial (Group 2) and Piwa–Quin (Group 3). Based on the CCA ordination biplot, significant differences were observed in floral characteristics and distribution depending on temperature, rainfall, soil pH, altitude, and topographic features. Based on Ward’s agglomerative clustering, it was found that Himalayan ‘Ecotone’ temperate conifer forests exhibit a rich and diverse floristic structure.
Development of allometric equation for the prediction of young Makila (Litsea angulata BI) biomass for handling climate change
Authors: Mardiatmoko Gun
Published: November 2024

Every plant is significantly important in tackling climate change, including Makila (Litsea angulata BI) an endemic wood species found in the forest of Moluccas Provinces. Therefore, this research aimed to examine the role of the Makila plant in tackling climate change by measuring biomass content using constructing an allometric equation. The method used was a destructive sampling, where 40 units of Makila plant at the sampling level were felled, and sorted according to root, stem, branch, rating, and leaf segments. Each segment was weighed both at wet and after drying, followed by a classical assumption test in data processing, and the formulation of an allometric equation. The regression model was examined for normality and suitability in predicting independent variables, ensuring there were no issues with multicollinearity, heteroscedasticity, and autocorrelation. The results yielded a multiple linear regression, namely: Y = −1131.146 + 684.799X1 + 4.276X2, where Y is biomass, X1 is the diameter, and X2 is the tree height. Based on the results of the t-test: variable X1 partially affected Y while variable X2 partially had no effect on Y. The F-test indicated that variables X1 and X2 jointly affected Y with R Square: 0.919 or 91.9% and the rest was influenced by other unexplored factors. To simplify biomass prediction and field measurement, a regression equation that used only 1 independent variable, namely tree diameter, was used for the experiment. Allometric equation only used 1 variable, Y = −1,084,626 + 675,090X1, where X1 = tree diameter, Y = Total biomass with R = 0.957, and R2 = 0.915. Considering the potential for time, cost, and energy savings, as well as ease of measurement in the field, the biomass of young Makila trees was simply predicted by measuring the tree diameter and avoiding the height. This method used the strong relationship between biomass, plant diameter, and height to facilitate the estimation of biomass content accurately by entering the results of field measurements.

A subsidised fertiliser policy is a clear option to increase rice production and maintain farmer benefits. It has proven to be costly and hence needs to be effectively calculated. This research proposes the use of advanced multi- disciplinary techniques to precisely estimate annual fertiliser demands for food production, based on the local field conditions and crop characteristics. Time-series satellite imageries (Landsat 8 Surface Reflectance of Operational Land Imager) were analysed to identify the annual cropping patterns, delineate agricultural field boundaries, and estimate land area. Monitoring and data collection on cropping patterns were conducted using normalised difference vegetation index (NDVI) data. The corrected rice field maps and cropping patterns were validated through field inspections. Subsequently, soil sampling and analysis were performed to determine precise fertiliser doses for each crop during each planting season. Finally, a fertiliser demand allocation map was created to inspect the results visually. A case study conducted in Jombang Regency, East Java Province, Indonesia, highlighted a gap of approximately 5.91 Mg urea and 1.02 Mg NPK in fertiliser demand measured using this study method as compared to the current subsidised fertiliser allocation. This gap could lead to an ineffective use of the fertiliser subsidy budget, which could jeopardise achieving the national food production target. Therefore, this study urges government stakeholders to implement the proposed method to maintain national food security in the country.

The importance of pet adoption is very important in efforts to support the prevention of animal abandonment. Currently, the pet adoption system in Indonesia still largely relies on a manual approach. This process is carried out directly without paying attention to important aspects of the match between the pet and its adopter, which can result in a lack of information which has a long-term impact on the abandonment or return of the pet. Based on these problems, this research aims to design and create an application that can facilitate the pet adoption process. This application was built for Android-based mobile devices by utilizing Machine Learning methods to provide personalized pet recommendations based on user preferences using Content-Based Filtering and making it easier to identify pet breeds from photos uploaded or selected by users using Image Classification. The pet data collected was sourced from the Kaggle, TensorFlow, and GitHub websites. It is hoped that the results of this research can overcome the problem of pet adoption in a better and more sustainable way and will not only provide benefits for abandoned animals, but can also reduce cases of animal abandonment due to irresponsible owners.

The choice of 1000 watt and 1500 watt inverters was chosen based on the load used in the designed prototype, namely 4 100 watt incandescent lamps with a total of 400 watts, taking into account the efficiency of the inverter device which is in the range of 80%.
The Psychosocial Impacts of Racism on the Development of Black Brazilian Adolescents: Dialogues Based on Vigotski's Historical-Cultural Clinical Psychology
Authors: Oliveira Neto José da Silva , Lima Ana Ignez Belém
Published: November 2024

Objective: The aim of this study is to analyze the psychosocial implications of racism in the development of black Brazilian adolescents, with the aim of contributing to the construction of theoretical and practical foundations for the work of the cultural-historical clinical psychologist.
 
Theoretical Framework: This study is based on the Historical-Cultural Psychology of L. S. Vigostki, a Soviet psychologist, and more specifically on the problematizations of Historical-Cultural Clinical Psychology, as well as on discussions and research into Ethnic-Racial Studies.
 
Method: This is an exploratory study and, more specifically, it was constructed using a Narrative Literature Review, using theoretical and bibliographical references and the research experience in cultural-historical clinical psychology of the Laboratory for the Study of Subjectivity and Mental Health (LADES-UECE) to reflect on the bases for the work of the cultural-historical clinical psychologist with black adolescents.
 
Results and Discussion: The results show that the experience of racism has profound psychosocial impacts on the psychic dynamics of black adolescents, with three main consequences for the formation of their personality: 1) dysfunctionalization of the cognition-affect unit; 2) disarticulation in the psychological function of concept formation; and, finally, 3) disorganization in the psychic activity of black adolescents. In addition, the results point to the weakness in the training of the cultural-historical clinical psychologist in terms of understanding what racism is, what its impacts are on the psychic development of the black individual, as well as the ability to manage these impacts.
 
Research Implications: The practical and theoretical implications of this research are that it provides fundamental directions for the work of the cultural-historical clinical psychologist, both on a theoretical level - addressing the construction of clinical reasoning in a psychological approach without much systematization in Brazil - and on a practical level - signaling intervention and management strategies in the face of psychological problems faced by black people in Brazil, especially black adolescents.
 
Originality/Value: In an original and unprecedented way, this study contributes to the literature in the field of historical-cultural clinical psychology, which is at the beginning of its construction in Brazil. Furthermore, from an ethical-political point of view, the study calls for cultural-historical clinical psychologists to carry out clinical practice in accordance with the philosophical-epistemological foundations of Vygotsky's psychology.
Clogging of Leachate Drains in Landfills due to Biochemical Precipitation: a Literature Review
Authors: Pfeiffer Simone Costa , Carvalho Eraldo Henriques de
Published: November 2024

Objective: Review the relevant literature and analyze the causes that lead to the clogging of leachate drains in landfills due to biochemical precipitation.
 
Theoretical Framework: Although leachate drainage systems have greatly evolved in terms of performance, clogging can occur in all designs due to physical, biological, and chemical mechanisms.
 
Method: To investigate the issue of clogging in leachate drainage systems, an extensive literature review was conducted through consultations on relevant websites. National and international technical papers were sought, as well as regulations from environmental agencies of different countries.
 
Results and Discussion: The removal of Chemical Oxygen Demand (COD), primarily in the form of acetic acid, transforms this stronger acid into weaker acids such as carbonic acid, which results in an increase in the pH of the environment. The concentration of carbonate also increases, consequently accelerating the precipitation of calcium carbonate. These precipitates are usually mixed with the biofilm and exhibit very characteristic shapes and structures.
 
Research Implications: The lifespan of a vertical landfill can be strongly determined by the clogging phenomena in the leachate drainage system. Therefore, the monitoring of this system must be carried out with great care.
 
Originality/Value: This review stands out for addressing a relevant and underexplored topic, especially in the national technical literature. Understanding the processes that can lead to clogging of the leachate drainage system is of interest to everyone working in the field, particularly those who design and/or operate a landfill.

Authors: Silva Valdene Carvalho Peixoto da , Ferreira Filho Hélio Raymundo , Nascimento-e-Silva Daniel
Published: November 2024

Goal: This article's main objective is to analyze the trends and challenges associated with the circular economy (CE) and reverse logistics (RL), with an emphasis on RL's role as a fundamental component of the CE.
 
Theoretical framework: The study's theoretical basis focused on the dimensions and analytical categories of the circular economy and reverse logistics as fundamental elements of environmental sustainability. The analysis considered reverse logistics an integral part of the circular economy to identify its challenges and opportunities.
 
Method and material: The method used was bibliographic. Data were collected from the Google Scholar, Elsevier, and Scielo databases to construct answers to three guiding questions related to a) the trends of the circular economy that allow understanding its integrative vision, the role of reverse logistics in the circular economy, and what are the challenges in implementing the circular economy. Twenty-eight articles on CE and 18 on RL were selected. The definition of the sample considered criteria of relevance, timeliness, and academic impact in articles published in the last fifteen years in high-impact journals. Furthermore, the studies were assessed for their thematic relevance, methodological robustness, and contribution to the development of the field of study. The results were generated using semantic and content analyses.
 
Results and Conclusion: The results found were that a) the trends of the circular economy are the regeneration of resources as a central priority, design is now occupying a central place in sustainability, and the change from ownership to performance, which structure the new human mentality; b) the role of reverse logistics in the circular economy is to promote sustainability in business in practice, mainly through legal structuring, as is the case of the National Solid Waste Policy (PNRS); and c) the main challenges in implementing the circular economy are the lack of understanding of its principles and the lack of cooperation between organizations, governments and consumers.
 
Research implications: It is necessary to start legally structuring and practicing reverse logistics now so that the collective mentality can soon collaborate effectively with sustainability.
 
Originality/value: The study shows that the degree of collaboration between governments, organizations, and consumers is crucial for overcoming the challenges and seizing the opportunities of reverse logistics.

Published: November 2024

Objetivo: Este estudo teve como objetivo validar e comparar três modelos de estimativa da radiação solar difusa na cidade de Natal - RN, utilizando dados do Projeto SONDA. Os modelos analisados foram Erbs, Bourges e Page, buscando identificar o mais adequado para as condições climáticas locais.
 
Referencial Teórico: A radiação solar difusa desempenha um papel crucial no desempenho de sistemas fotovoltaicos. Para otimizar esses sistemas, especialmente em regiões tropicais como Natal - RN, é necessário estimar com precisão as frações de radiação direta e difusa. Modelos precisos de estimativa são essenciais para esse fim.
 
Método: Dados radiométricos de Natal, fornecidos pelo Projeto SONDA, foram utilizados. A análise comparou os modelos de Erbs (1982), Bourges (1992) e Page (1961), utilizando métricas estatísticas como Erro Médio Absoluto (MBE), Raiz do Erro Quadrático Médio (RMSE), eficiência e variabilidade. A correlação entre o índice de claridade (Kt) e a fração difusa (Kd) foi explorada.
 
Resultados e Discussão: O modelo de Erbs apresentou maior precisão, com valores mais próximos aos observados, seguido por Bourges, que também mostrou bom desempenho. O modelo Page subestimou consistentemente os valores de radiação difusa, sendo o menos eficaz para Natal - RN. A análise estatística confirmou a adequação dos modelos de Erbs e Bourges para essa localidade.
 
Implicações da Pesquisa: Os modelos de Erbs e Bourges podem ser aplicados em regiões com condições climáticas semelhantes, auxiliando no planejamento de sistemas solares eficientes.
Autocorrelation and Cross-Correlation of Hospitalizations for Syphilis and HIV/AIDS in the State of Bahia
Authors: Jesus Samuel José Amaral de , Araújo Edna Maria de , Silva Filho Aloísio Machado da
Published: November 2024

Objective: To identify and estimate the autocorrelation and cross-correlation of time series of hospitalization rates for syphilis and HIV/AIDS in the State of Bahia, in the period from 2000 to 2020.
 
Theoretical Framework: It is based on the characterization and factors associated with notifications of syphilis and HIV/AIDS infection, as well as the social determinants that influence access to health programs and policies.
 
Method: This is a time-based ecological study, carried out using data from the Hospital Information System (SIH) and the Brazilian Institute of Geography and Statistics (IBGE). The analyses were performed using the Detrended Fluctuation Analysis (DFA) method and the cross-correlation coefficient ρDCCA.
 
Results and Discussion: There was persistent behavior for the time series of hospitalizations due to syphilis and HIV/AIDS (αDFA > 0.50), in addition to a weak negative cross-correlation (< -0.20), with only the autocorrelation of syphilis being statistically significant. It is believed that the behavior described tends to occur in the long term and may be repeated in the coming years, if interventions that contribute to the reversal are not carried out, both for the diseases in isolation and for co-infection.
 
Research Implications: The findings of this research may contribute to updating knowledge about syphilis and HIV/AIDS infection in adults, but mainly to the construction of indicators with an emphasis on health surveillance systems in the State of Bahia.
 
Originality/Value: The study aims to analyze hospitalization cases in which syphilis or HIV/AIDS was the main diagnosis, thus corroborating the planning and strengthening of public policies.

The mixing of unpermitted drugs with health supplements to increase effectiveness can cause negative effects to consumers, requiring quality testing of these products. In this study, an analytical method for simultaneously determination of 5 anti-diabetic drugs (ADDs) (i.e., metformin, phenformin, buformin, glibenclamide, and gliclazide) in health supplement samples was developed with a combination of ultrasonic extraction, dispersive solid-phase extraction (d-SPE), and liquid chromatography tandem mass spectrometry (LC-MS/MS). Hard capsule, soft capsule, and liquid samples were extracted with methanol twice, followed by activated carbon addition for extract clean-up and LC-MS/MS quantification. The analytical method was validated through various factors such as: specificity, limit of detection, limit of quantification, linearity, repeatability, and recovery. The method had high precision (mean recovery from 88% to 99%, relative standard deviation lower than 10%) and low detection limit of 0.1 mg/kg, meeting the requirements of detection of these substances at trace to ultra-trace levels in complex sample matrices. The validated method was then applied to analyze concentrations of 5 ADDs in 30 health supplement samples. Metformin was detected at a concentration of 2.20 mg/kg in one hard capsule sample, while the remaining samples did not contain ADDs at detectable levels.
