Andar de bicicleta... Capacete, usar ou não? Eis a questão: fatores determinantes em jovens do concelho da Figueira da Foz (2014-2016)
Authors: Eufrásio Ricardo , Lopes Fernando , Vitória Fernanda , Branco Manuela , Amélia Lúcia
Published: October 2024

Os traumatismos cranioencefálicos constituem a principal causa de morte e incapacidade grave nos acidentes de bicicleta. Realizou-se um estudo para identificar os fatores determinantes na sua utilização pelos jovens no Concelho da Figueira da Foz. Definiu-se uma amostra de 1089 alunos ciclistas, matriculados nos Agrupamentos de Escolas do Concelho da Figueira da Foz. Aplicou-se inquérito por questionário, auto-preenchido, medindo as motivações relativamente à titularidade e utilização do capacete. Na identificação dos fatores determinantes incluímos as variáveis independentes num modelo de análise de regressão logística múltipla, calculando-se os Odds Ratios ajustados. Registou-se que 27 % dos alunos referiram a experiência de pelo menos um acidente de bicicleta com traumatismo cranioencefálico, sendo esse risco superior nos rapazes (ORa: 1,9; IC:95 %:1,5-2,6; p<0,05). Em 90 % dos acidentados, não intervieram veículos automóveis ou motorizados, envolvendo apenas o próprio ciclista, resultado de despistes ou colisões com obstáculos. A utilização do capacete é determinada consoante a literacia (OR: 2,5; IC:95 %:1,6-3,6; p<0,05), o 5º e 8º ano de escolaridade (OR: 3,6; IC:95 %:2,3-5,7; p<0,05 e ORa: 1,9; IC:95 %:1,3-2,7; p<0,05, respetivamente) e a utilização recreativa da bicicleta (OR: 2,8; IC:95 %:1,3-5,9; p<0,05). A ausência de pro-atividade no uso do capacete, evidenciou-se quando 77 % dos alunos consideravam-no o equipamento mais importante, e apenas 28 % o utilizavam regularmente. A idade é um dos principais fatores determinantes na utilização do capacete. As campanhas de promoção poderão ser eficazes nas crianças em idade escolar. O capacete é uma proteção individual que deve ser incentivada.

The Notion of causality for David Hume is an Anathema; A Critique
Authors: Enekwe Franklin Sochima
Published: October 2024

This work critically examines David Hume's notion of causality, which he posits as ananathema to traditional understandings of cause and effect. In classical philosophy, causality isseen as a necessary and intrinsic link between cause and effect, forming the basis of scientificinquiry and rational thought. Hume, however, challenges this view by arguing that our perception ofcausality is not derived from any inherent connection but from habitual association formed throughrepeated experiences. This skepticism casts doubt on the reliability of inductive reasoning and thefoundations of scientific knowledge. The paper explores Hume's arguments, their implications fornatural laws and scientific practice, and critiques from philosophers like Immanuel Kant, who assertthe necessity of causal reasoning for coherent experience and scientific inquiry. By integratingthese perspectives, the paper proposes an alternative framework for understanding causality thatreconciles empirical observation with the rational structures of the human mind.
Happy Life: The only means to R.I.P
Authors: Ugwu Abel Friday
Published: October 2024

The pursuit of happiness is a universal human aspiration, deeply embedded in culture and philosophy. This article explores the relationship between happiness and the acceptance of life's inevitable end—death. By examining historical and modern perspectives on happiness, we argue that cultivating a fulfilling and happy life can serve as a means to approach death peacefully, potentially yielding a more meaningful existence. We analyze various frameworks of happiness, including psychological well-being, existential fulfillment, and the social dimensions that contribute to a happy life. Additionally, this paper draws upon philosophical insights from figures such as Epictetus and Viktor Frankl to highlight how happiness can transform a dignified acceptance of death, thus allowing individuals to truly Rest in Peace (R.I.P.)
What they Think, and not really what they Talk: Understanding the Hidden Narrative.
Authors: Agu Emmanuel Tochukwu
Published: October 2024

In our complex social world, communication is not simply a matter of exchanging words. Indeed, the true essence of interpersonal relationships often lies beneath the surface of spoken language. This article explores the concept of the hidden narrative—those unspoken feelings and opinions that shape how we perceive ourselves and how others perceive us., it argues that what people think about us may carry more weight than what they express aloud.
Isolated Acute Liver Injury Following Mass Envenomation by Wasps
Authors: Solanki Hayneil , Fox Tara , Chin Jerry
Published: October 2024

Acute liver injury from wasp venom exposure has been reported in the literature, most often in the context of anaphylaxis and multiorgan injury. We present a case of isolated liver injury, a rare presentation, in a healthy 26-year-old man stung by more than 40 wasps. We observed a delayed presentation with conjugated hyperbilirubinemia, significantly raised transaminases, and mild coagulopathy, in the absence of other organ involvement. Complete normalization of liver enzymes was seen 61 days following presentation. Clinicians encountering patients with liver injury in the context of wasp stings should consider wasp venom-associated hepatitis as a possible cause.
Transitar outros movimentos do aprender no processo de ensino da leitura
Authors: Rôxo Maria do Rosário
Published: October 2024

As práticas pedagógicas, construídas de forma hegemónica e padronizada, podem ter um impacto significativo na vida das pessoas, sobretudo na relação linguagem e saber (Baptista, 2022; Santos; Santana, 2022; Couto; Jovino, 2022; Pinheiro; Lacerda; Coelho, 2022). Com base nos princípios da pesquisa qualitativa e interpretativa (Denzin; Lincoln, 2006; Moita Lopes, 2004), este artigo tem como objetivo discutir como as práticas pedagógicas de leitura apagam o conhecer e como esse apagamento tem implicações na relação “sujeito-leitor”, que é, por conseguinte, condicionada a atitudes de colonialidade linguística (Baptista, p. 54). Como contributo, os resultados do estudo demonstram o quanto: (a) a leitura requer mudanças de paradigmas em termos da relação ensino-aprendizado e (b) o transitar em relação à leitura relaciona-se às práticas de resistência, a um agir político (Moita Lopes; Pinto, 2020) num jogo em que o discurso como prática faz circular sistemas de invisibilidades e seus efeitos de separação (Foucault, 2016).
A translinguagem como possibilidade de Educação para a Cidadania Global crítica e descolonial
Authors: Marins Emily de Paula Silva , Costa Daianny Madalena , Abba Maria Julieta
Published: October 2024

O presente texto tem por objetivo analisar a translinguagem como possibilidade de Educação para a Cidadania Global (ECG) crítica e descolonial a partir do estudo de quatro publicações da Organização das Nações Unidas para a Educação, a Ciência e a Cultura (UNESCO) no período de 2015 a 2018. Metodologicamente, ancora-se na análise de conteúdo, em suas três esferas – pré-análise, exploração do material e tratamento, inferência e interpretação dos resultados. Perspectivados sob a compreensão de que a ECG se organiza ainda em um processo histórico que reitera a colonialidade, há possibilidades de transgressão nas quais a translinguagem e a ECG se amalgamam em um movimento crítico como elementos imprescindíveis para a descolonialidade. Isso porque translinguajar traz no cerne de sua constituição recursos teóricos-práticos-pedagógicos que promovem a ruptura entre superiores e inferiores calcados no paradigma monolíngue-colonial fortemente percebidos no contexto de uma América Latina livre, soberana e cidadã. Por meio da translinguagem, a ECG afirma espaços educativos ancorados na justiça social, nos direitos humanos e ambientais. Conclui-se, por fim, que, mesmo sendo a Unesco um organismo internacional vinculado à Organização das Nações Unidas, encontram-se aportes para a construção de um mundo mais solidário, que respeita à diversidade e que valoriza o senso de humanidade compartilhada entre todos os seres da Casa Comum.

Published: October 2024

O objetivo do texto é apresentar o segundo dossiê sobre o “Movimento lógico-histórico dos conceitos: formação de professores, ensino e pesquisas”. Em sua maioria, os autores em seus artigos exploram o movimento lógico-histórico de conceitos matemáticos para organizar o ensino e/ou promover processos de formação continuada de professores que superem as formas de ensino da didática tradicional. Para tanto, percebe-se a necessidade de resgatar bases históricas do conhecimento matemático e em alguns casos são adotados os pressupostos da Atividade Orientadora de Ensino, para elaboração de situações de ensino para estudantes ou para o processo de formativo de professores que se aproximem de situações desencadeadoras de aprendizagem.
O movimento lógico-histórico na educação infantil: perspectivas para o ensino de Matemática
Authors: Viviani Camila Fernanda Biolcatti
Published: October 2024

Este artigo tem como objetivo discutir sobre o ensino de Matemática na educação infantil com base no movimento lógico-histórico, a partir da fundamentação teórica do Materialismo Histórico-Dialético e da Teoria Histórico-Cultural.  Defende-se que o ensino de Matemática seja intencionalmente planejado pelo professor na perspectiva do pensamento teórico dialético desde a educação infantil. Destarte, o pensamento conceitual e científico é a base das neoformações e do processo de aprendizagem. O conceito é produto das necessidades sociais, sendo, assim, direcionado por um motivo. Apresenta-se a Atividade Orientadora de Ensino como base teórico-metodológica para a formação do pensamento conceitual nos processos de ensino e aprendizagem e as Situações Desencadeadoras de Aprendizagem como recurso para sistematizar um problema desencadeador da aprendizagem de determinado conceito. Este artigo é resultado de uma pesquisa teórico-bibliográfica, fundamentada no movimento logico-histórico.  Nesta perspectiva, apresentamos as Situações Desencadeadoras de Aprendizagem como possibilidades para o trabalho docente, propondo, como exemplo, uma atividade baseada na história virtual do conceito. Espera-se ter contribuído para a defesa do ensino desenvolvente na educação infantil e da importância da aprendizagem no desenvolvimento do psiquismo humano.
A lógica do pensamento e a lógica matemática: uma análise epistemológica a partir do estudo do movimento lógico-histórico do conceito de medida
Authors: Sarmento Alan Kardec Carvalho
Published: October 2024

O presente artigo tem como objetivo discutir a problemática da consistência da matemática no contexto da lógica formal e sua relação com a lógica do pensamento, relacionado com o desenvolvimento Lógico-Histórico do conceito de medida como forma de materialização  da tese segundo a qual a lógica da matemática, enquanto lógica do pensamento, não apenas engloba a lógica formal, mas a supera, à medida que considera o conteúdo cultural e social dos conceitos matemáticos e as condições originárias deles, que os trouxeram ao mundo concreto, o que é indispensável para uma investigação baseada no movimento Lógico-Histórico. A metodologia consistiu em uma revisão bibliográfica, a partir da qual, foi possível realizar uma análise histórico-epistemológica, relacionando a lógica matemática, a lógica formal no contexto da lógica do pensamento para elaborar uma síntese histórica que engloba a origem, os fundamentos matemáticos e o conteúdo social subjacentes ao conceito de medida, buscando elementos epistemológicos que possibilitem elucidar o processo de construção das medidas. De modo geral, os resultados dão suporte à principal tese defendida nesse artigo.  Além disso, corrobora com a tese de Kopnin (1978), pela a qual a lógica fundamental do pensamento se dirige em ascensão do simples ao concreto, do inferior ao superior, que reflete as leis que determinam o desenvolvimento do conceito no mundo objetivo.
ABORDAGEM ESPACIAL MULTIVARIADA APLICADA AO ESTUDO DA VARIAÇÃO DE MÉDIO PRAZO DA LINHA DE COSTA

Published: October 2024

As frentes oceânicas se caracterizam pela intensa dinâmica e vulnerabilidade, em função da ação conjunta das forçantes oceanográficas, meteorológicas e antropogênicas. Com isso, existem diversas abordagens para mensuração dessa dinâmica, destacando-se aquelas derivadas de dados de sensoriamento remoto, com base em indicadores, como a linha de costa. Esta se configura como a interface entre a área marinha e continental, podendo ser indicada pelo limite entre a área seca e úmida, e que não considera espessura ou diâmetro. Entretanto, a depender do método e dado aplicados, esses prognósticos têm maior ou menor incerteza/precisão espacial. A presente investigação, a partir de dados do satélite Landsat 5 e 8 do período de 2011 a 2018, aplicou duas abordagens (DSAS e Cassie) para estimar as variações da linha de costa da Praia do Icaraí, Ceará. Os resultados apontaram divergências entre as abordagens:  o DSAS derivou um cenário de predomínio de processos erosivos e a Cassie um predomínio de progradação. Com base nas campanhas e dados de campo, bem como, na literatura, constatou-se que os dados do DSAS estão mais congruentes com a realidade local, representado uma variação líquida de -8,10 m e uma taxa de variação de -2,32 m/ano da linha de costa.
O SETOR FARMACÊUTICO GLOBAL: NÚMEROS E DINÂMICAS
Authors: Stacciarini João Henrique Santana
Published: October 2024

Pesquisadores de diversas áreas do conhecimento científico têm se dedicado a investigar as múltiplas características do setor farmacêutico. Com o objetivo de contribuir com esse debate e fornecer subsídios para discussão, esta pesquisa se dedicou a coletar, interpretar e disponibilizar dados e informações relacionados ao setor farmacêutico em escala global. Descobriu-se que a receita anual do setor quase quadruplicou nas últimas duas décadas, atingindo 1,48 trilhão de dólares em 2022. As 20 maiores companhias possuem valor de mercado combinado de 3,5 trilhões de dólares, ativos no valor de US$ 1,86 trilhão e geraram a receita de US$ 820 bilhões, resultando em lucros de US$ 181,6 bilhões. De natureza oligopolista, grande parte das empresas líderes está concentrada nos EUA e na Europa, embora um conjunto de indústrias em "países farmaemergentes", especialmente na Ásia, tenha ganhado força. O consumo farmacêutico, embora ainda bastante concentrado em países desenvolvidos, também tem se expandido em países emergentes. Essa tendência é impulsionada por nações como Brasil, Rússia, Índia, China e África do Sul (BRICS), bem como México, Indonésia, Coreia do Sul e Turquia (MIST). Juntos, estes nove países já representam 48% da população mundial e contribuem com 31% do Produto Interno Bruto (PIB) global.
THE HILEIA BAIANA IN THE ATLANTIC RAINFOREST BIOME: HAS THE TRANSITION FROM FORESTS TO MONOCULTURES ALTERED THE VOLUME OF RAINFALL?
Authors: Souza Fernando Rios de , Silva João Batista Lopes , Brito Júnior Bento Santos de , Nunes Ely de Jesus
Published: October 2024

Human activities have been affecting the climate all over the globe, making extreme weather events increasingly common. In the controversial relationship between man and the environment, a particular region within the Atlantic Rainforest Biome, the Hileia Baiana, stands out as one of the richest and most fragile hotspots on the globe. Despite its biological importance, this region has suffered decades of indiscriminate deforestation, reducing the original biome to less than 10%. Therefore, it was checked whether the loss of natural vegetation caused significant rainfall changes. To this end, the present study evaluated the rainfall stations in the area of influence of this study between 1943 and 2020, with a buffer of 30 km beyond its boundaries. The results showed 14 stations with a reduction in rainfall volumes at the 5% significance level. Between 1984 and 2021, there was a reduction in 3,542.15 km² of Atlantic Forest, in contrast to an increase of 4,845.45 km² in silviculture areas, in the Hileia Baiana region. Our findings indicate rainfall changes coinciding with areas that are no longer covered by the Atlantic Rainforest and gave way to pastures, agriculture, and forestry, concluding that the landscape changes are directly related to climate behavior in the region.

Published: October 2024

O objetivo deste estudo foi realizar simulação preditiva de desmatamento na bacia do Alto Paraguai no estado brasileiro de Mato Grosso, com o propósito de gerar informações para subsidiar estratégias de planejamento territorial voltadas à conservação ambiental. A modelagem foi operacionalizada no programa Dinamica EGO, a partir de dados de cobertura vegetal e de usos da terra, referentes ao período de 1985 a 2020, associado a variáveis explicativas do desmatamento na área investigada. Cinco etapas foram realizadas na metodologia: cálculo das matrizes de transição, determinação dos pesos de evidência, ajuste, validação e projeção do modelo no cenário tendencial para o ano de 2050. O modelo de simulação construído apresentou grau de acurácia de 75,60%. Três variáveis motrizes foram consistentemente associadas ao estímulo de desmatamento (proximidade às áreas previamente desmatadas, às estradas e às cidades). Em contrapartida, a proximidade às áreas protegidas apresentou um desestímulo ao desflorestamento. Para o ano de 2050 foi projetado para a bacia a perda de 21,20% (21.129,05 km²) de áreas de vegetação natural e aumento de 29,81% (21.135,47 km²) das áreas antrópicas agrícolas. Nesse cenário as áreas antrópicas agrícolas terão 92.029,92 km², superado as áreas de vegetação natural com 78.507,56 km² em 2040.
Vigilância: Punição e Depredação escolar
Authors: Guimarães Aurea Maria
Published: October 2024

Meu objetivo nesse trabalho foi demonstrar as possíveis relações entre vigilância – punição e depredação escolar. À medida que eu ia trabalhando sobre esse tema fui percebendo que ele estava muito ligado à minha própria violência, ao meu próprio autoritarismo, aos meus próprios esquemas de vigilância e punição. A partir dessa percepção ficou um pouco mais fácil entender as teses do filósofo Michel Foucault. Este filósofo nos alerta dizendo que o poder não é uma instância separada da sociedade, encarnada somente na figura do Estado com função exclusivamente repressiva. O poder é produtivo, criativo, acha-se difundido pelo interior das relações sociais, espraiando-se em todas as direções, criando novas formas de sujeição e de dominação. Como é que esse poder de dominação se espalha da sociedade? Com a ajuda de todos nós. Cada um na sua atividade expressa aquele poder que parece existir apenas no topo dirigente da sociedade. Cada um de nós se submete porque espera submeter os outros ao seu próprio poder, por menor que este seja. [...]

Algumas reflexões sobre o sistema de avaliação
Authors: Oliveira Fernando Antônio Leite de
Published: October 2024

Desde 1980 têm-se feito discussões, na Universidade Federal de Uberlândia, para mudar o sistema de avaliação. Em diversas ocasiões, foram feitas consultas a diversas instância da comunidade sobre o quê e em que todas as vezes a discussão ficou retida em algum ponto sem que houvesse um progresso, nos passos seguintes. A rigor, a única mudança visível em todo esse período foi a eliminação das provas finais do semestre. A discussão sobre a alteração da nota mínima de aprovação, de 54 para 60 ou 70 pontos foi marcada, em 83 e 84, por um artificialismo em torno de um valor aleatório que pudesse significar um maior rigor ou grau de exigência desejável. Um dos argumentos que emergiam, na época, foi o de que um aluno da UFU estaria em desigualdade de condições de competição, ao concorrer por uma vaga no mercado de trabalho, quando comparado com algum aluno de outra Universidade que tivesse um grau de exigência maior.

Os procedimentos idealista e materialista do investigador no trabalho de campo
Authors: Soares Neto Cícero José Alves
Published: October 2024

Objetiva-se refletir, neste escrito, acerca de um problema específico na formação do pesquisador de campo: o procedimento idealista ou materialista do investigador no trabalho de campo.  Porém, não se cogita abordar a questão num prisma abrangente a todos que enveredam por um trabalho de campo, pois esta preocupação limita-se aos que se dedicam ao espaço das Ciências Sociais. A reflexão tem, pois, um terreno restritivo para caminhar: o pesquisador social. Entretanto, não se propõe atacar a preocupação num nível especulativo aos pesquisadores sociais, pois faltam parâmetros teóricos e concretos para o aprofundamento do problema. Enfim, prende-se a abordagem da questão à prática de um caso particular, à de uma pesquisa de campo que serviu ao projeto que redundou numa dissertação de mestrado: O Seridó e os Votos de Porteira Batida. Contudo, isto não quer dizer que se ficará unicamente preso aos limites desta experiência de pesquisa de campo, pois, na realidade, este caso particular servirá como um ponto estratégico (concreto) em torno do qual se dará a reflexão que visará lançar pontos de discussão.

RC Frame Behavior at a Column Collapse Scenario Considering Crack Opening Effects
Authors:   National Research Moscow State University of Civil Engineering,, Y. Savin Sergei
Published: October 2024

This study examines the influence of the reinforced-concrete frame topology and crack opening effects on the structural behavior under a column removal scenario. For this purpose, a variant of discretization of the finite element model has been proposed, which takes into account additional rotations during the formation of discrete cracks. As a criterion of the bearing capacity of structures, the equilibrium point at the forcedisplacement curve was adopted. Verification of the proposed method has been performed using experimental data for a U-shaped frame. The paper provides a comparative analysis of the calculation results for 3-story, 5-story and 9-story reinforced-concrete frames using structural elements and the proposed method. It is found that accounting for the discrete nature of cracks had practically no effect on the magnitudes of axial forces in the elements. However, for bending moments, the proposed method showed a decrease compared to the traditional approach. The increase of axial tensile forces in the support sections of the beam above the zone of local failure has been detected for reinforced-concrete frames with 3 - 5 stories, which can lead to an increase in the influence of buckling for the columns to which such a beam is adjacent. Keywords: Reinforced concrete, Frame, Failure, Crack, Modeling, Finite element method, Moment, Angle of rotation.
Study on the Stress and Deformation Laws and Work Principles of the Pull-pile Supporting Structure in a Deep Foundation Pit
Authors:   Shandong University of Technology,, Lan Binpeng
Published: October 2024

In combination with the field monitoring data, PLAXIS3D finite-element software was used to numerically model the pull-pile supporting structure in a deep foundation pit. This structure was compared to the single-row pile support structure in order to learn more about the pull-pile supporting structure's force and deformation characteristics and how it works. The study found that the cumulative horizontal displacement curves of the supporting piles are integrated into an “upward convex” shape. The bendingmoment curve of the front-row piles presents an “inverted S” shape, and the bending- moment curve of the back-pull piles presents a “bow” shape. The “back-pull-pile effect” can improve the unbalanced distribution of positive and negative bending moments in single-row piles by changing the stress condition of the soil. In other words, the pull-pile supporting structure has good safety and serviceability and can well control the lateral displacement of the foundation pit. Keywords: Deep foundation pit, Pull-pile supporting structure, Stress and deformation laws, Work principles
Using Statistical Methods to Analyze 32 Years of Rainfall Data in Amman, Jordan
Authors:   University Sains Malaysia, Almawas Mohammad
Published: October 2024

The construction of hydraulic structures, bridges, culverts, canals, stormwater sewers, and road drainage systems relies on rainwater. Calculated capacities and associated design of required structures based on collected data mandate that these structures can operate properly under various weather conditions and discharge the water that they will be exposed to. Hydrological studies observe flood hazards and plan water resource management using rainfall data. Four rain gauge stations near Amman-downtown (Ras Al-Ain area) were selected for statistical analysis. To comprehend normal, deficiency, excess, and seasonal rainfall of the chosen circle headquarters, 32 years of daily rainfall data are used. This analysis predicts rainfall and plans water resource management. Moreover, it helps determine return periods. This approach aids disaster and crisis management planners and decision-makers to analyze water availability and develop strategies for its storage using statistical measures to assess the variability of monthly and yearly rainfall. By analyzing rainwater for 32 years, the results revealed that Weibull method is 99% in agreement with the average rainfall for all selected stations. Expected maximum discharge for different return times (return times range from 5 to 100 years) was used to fit statistical distributions of (2156.1 mm, 2656.4 mm, 3270.9 mm, 3741.2 mm, and 4221.5 mm), which was identical to the average annual maximum precipitation amount based on positioning methods for all stations. As a result, this technique provides the best matching annual precipitation. Findings revealed that rainfall pattern exhibits irregularity and the probability distribution that provided the best match was determined by minimizing the discrepancy between the observed values and the estimated values. Keywords: Floods, Amman, Rainfall patterns, Return periods, Statistical analysis, Hydraulic structures.
Numerical Modeling of Structural Steel Elements Fabricated Using Wire and Arc Additive Manufacturing
Authors:   The British University in Egypt,, Mamdouh Nada
Published: October 2024

Additive manufacturing (AM) has revolutionized numerous industrial fields by enabling the production of intricate shapes that were previously impractical to manufacture using traditional methods. Recently, AM has been adopted in the construction industry. One of the key challenges in researching additively manufactured (AM’d) parts is accurately modeling and analyzing their thermal and mechanical responses and considering the imperfections resulting from the temperature variation during the printing process. This requires a comprehensive understanding of the interplay between various parameters, such as the printing process, and material properties. Overcoming these challenges is crucial for improving the reliability and performance of AM'd parts. Consequently, this research provides a step-by-step modeling and simulation of AM’d parts using ABAQUS software. Specimens with different test setups and printing directions were used for simulation. Four simulations had been created for specimens using layer-by-layer method to represent the 3D printing process fabricated using wire and arc additive manufacturing (WAAM). Also, finite element modeling was performed to investigate the specimen response under the application of tension and compression loads. This research provided insights into the differences in modeling the mechanical properties relative to the printing directions and where the tensile and compressive capacities were greatly influenced. Keywords: WAAM, Tensile testing, Finite element analysis, Stainless steel.

Based on the results of the research on the classification of economic development, it is evident that areas with advanced and fast development are Yogyakarta and Sleman, while fast-developing areas include Kulonprogo, and relatively underdeveloped areas are Gunungkidul and Bantul. The results of the Williamson Index indicate that the largest development inequality exists in the Kulonprogo, Bantul, and Gunungkidul areas, suggesting that there is inequality in community access to development outcomes. Furthermore, the results of the panel data regression show that the economic growth variable has an insignificant negative effect on development inequality, the unemployment variable has a significant positive effect on development inequality, and the HDI variable has a significant negative effect on development inequality in DIY Province. To reduce development inequality in DIY Province, it is necessary to increase employment opportunities based on regional potential and improve human resources to achieve inclusive economic growth.

Human resources are the most important factor in managing the available natural resources. Population growth from time to time can be a driving or inhibiting factor in economic growth. A process of economic development cannot be separated from population growth. This is related to resources that support economic development, in which human resources are the most important aspect of development besides natural resources, capital/technology, and social politics. This research aims to see the effect of education, minimum wages, investment, and economic growth on employment in Java and Bali in 2012-2022. The method used is Panel Least Square (PLS). The results show that education and minimum wages have an insignificant effect on employment. Investment and economic growth have a significant and positive effect on employment. The implementation of wages for workers needs to be reviewed so that the wages received can provide peace in living life. The increase in the minimum wage must be able to be collaborated with always learning and increasing capabilities for the needs of the world of work. Government policies in maintaining the momentum of economic growth after the COVID-19 pandemic by accelerating national economic recovery need to be increased. Carrying out realization and working with foreign countries in bringing in investment is needed so that the absorption of labor is higher.

This study analyzes the factors influencing labor demand in Indonesia during the 2015-2023 period. The background of this research is based on the importance of inclusive and stable economic growth to improve public welfare by increasing employment opportunities. Labor demand in this study is measured based on several key variables, namely Real Wages, Gross Regional Domestic Product (GRDP), and Investment. The analysis method used is the Panel Data Fixed Effect Model (FEM). This study uses secondary data obtained from the Badan Pusat Statistik and other relevant reports. The results show that, partially, Real Wages and GRDP have a significant effect on Labor Demand, while Investment does not have a partial effect on Labor Demand.

The aim of the study was to determine the relationship between disorders of menstrual function in adolescence and the risk of nonalcoholic fatty liver disease (NAFLD) with comorbid gastrointestinal pathology.
Materials and methods. We examined 129 adolescent girls aged 12–17 years with menstrual disorders (61 with abnormal uterine bleeding (AUB) and 68 with oligomenorrhea (OM)) and measured anthropometrics, indices of lipid and carbohydrate metabolism and liver enzymes. Data are presented in the form of mean (M), standard deviation (SD) and median (Me), a factorial model was developed.
Results. The study shows the peculiarities of the clinical course of menstrual function disorders in girls of puberty age. Patients with AUB were characterized by significantly lower average body mass indices, they were younger compared to patients with OM. The nature of metabolic changes that depended on the type of menstrual disorders in teenage girls was clarified. Adolescents with AUB had statistically significantly higher average levels of immunoreactive insulin, HOMA index, triglycerides, very low-density lipoprotein cholesterol, aspartate aminotransferase. This creates conditions for the formation of nonalcoholic fatty liver disease. A model was created regarding the participation of dyslipoproteinemia, changes in the carbohydrate spectrum and levels of liver enzymes in the formation of nonalcoholic fatty liver disease in girls with menstrual cycle disorders.
Conclusions. Disorders of menstrual function are associated with an increased risk of NAFLD formation. Adolescent girls with menstrual disorders need metabolic screening. The atherogenic profile of lipoproteinemia, marked changes in the carbohydrate spectrum and increased serum levels of liver enzymes in girls with menstrual cycle disorders are the basis for the formation of nonalcoholic fatty liver disease.
Detection of objects with diverse geometric shapes in GPR images using deep-learning methods
Authors: Apaydın Orhan , İşseven Turgay
Published: October 2024

Buried objects with regular geometric shapes appear as hyperbolic structures in ground-penetrating radar (GPR) images. The shapes of these hyperbolic structures differ depending on the geometric shapes of the objects. In this study, current deep learning-based object detection algorithms such as Faster R-CNN, YOLOv5, and single-shot detector are used to detect hyperbolic structures in GPR images and classify the buried object according to its geometric shape. A mixed data set is produced for training the models. A GPR measurement device is designed with a vector network analyzer and Vivaldi antenna pair to be used in laboratory measurements. Objects with rectangular and cylindrical geometric shapes are placed under the table and measurements are performed. The measurement scenarios created in the laboratory are modeled in the gprMax program and synthetic GPR data are produced. Data augmentation techniques such as flipping and resizing are applied to expand the data set. As a result of the training, three models successfully detect the objects and classify them according to their geometric shapes. The Faster R-CNN model gives the most accurate detection and classification with the metrics classification loss = 5.4 × 10−3, localization loss = 9 × 10−3, regularization loss = 5.1 × 10−5, mAP@0.5 = 1, and mAP@0.5:0.95 = 1.

Published: October 2024

Normalized difference vegetation index (NDVI) and land surface temperature (LST) are important indicators of ecological changes, and their spatial and temporal variations and spatial coupling can provide a theoretical basis for the sustainable development of the ecological environment. Based on the MOD13A1 and MOD11A2 datasets, the spatial distribution characteristics of NDVI and LST from 2000 to 2020 were analyzed, and the trend change slope method and spatial coupling model were used to calculate the significant changes. Finally, the spatial coupling model was used to calculate the spatial coupling degree between NDVI and LST. The study shows that: (1) From 2000 to 2020, the annual NDVI value of the Mu Us Sandy Land was between 0.25 and 0.43, showing a stable upward trend overall, with an increase rate of 0.074/(10a). The proportion of improvement areas in the study area is 81.48%. (2) There are significant differences in the spatial distribution of surface temperature in Mu Us Sandy Land, showing an overall trend of decreasing from northwest to southeast and higher in the west than in the east. The LST of Mu Us Sandy Land is greatly affected by changes in land use types. The spatiotemporal variation trend of LST is different from the gradual warming trend of global climate change. The main reason is that human activities have changed land use types and increased local vegetation coverage. (3) There is a significant negative correlation between LST and NDVI in Mu Us Sandy Land, with an R
2 of 0.5073 and passing the significance test at the 0.01 level. This indicates that ecological engineering policies can effectively reduce LST in the study area, thereby achieving the effect of improving the environment. The overall spatial coupling between LST and NDVI is at a very high level, with an average coupling degree of 0.895 in the study area. The two mainly exhibit a state of mutual antagonism in space, reflecting the importance of green vegetation in regulating regional climate and LST. The vegetation index and spatiotemporal variation of LST in Mu Us Sandy Land are the result of the joint influence of human activities and climate change, and human activities dominated from 2000 to 2020.
