Authors: Corso Angela Maria 
Published: September 2024

Este artigo tem como objetivo discutir as práticas de tempo livre e lazer das juventudes, balizando as relações sociais de gênero nestas práticas sociais. A pesquisa foi realizada na cidade de Irati, no estado do Paraná, mediante questionário e entrevistas. Foi aplicado questionário com 346 estudantes, de três escolas públicas e entrevistados 23 jovens de uma das escolas. A análise apoia-se nos estudos sociológicos da juventude, em Sposito e Abramo, no conceito de consubstancialidade para a análise das relações sociais de sexo, classe e gênero, em Kergoat e no conceito de performatividade de gênero, em Butler. Os dados apontam que as relações sociais atravessam os modos de vida das juventudes, confirmado que na sociedade de classe há lugares diferentes para homens e mulheres nas atividades de tempo livre e lazer, como a prática de esporte, dança, jogos eletrônicos, bem como na mobilidade para circular na cidade e no convívio social.

Published: September 2024

O estudo apresentou, sob o prisma interseccional, as dimensões que influenciam o sofrimento ético-político das mulheres amazônidas durante a trajetória de escolarização no ensino superior e as que contribuem para que elas permaneçam na universidade. O sofrimento ético-político sentido nos corpos das mulheres amazônidas considera o contexto ético-político que abrange as intersecções de gênero, regionais, étnico-raciais, socioeconômicas, culturais e ambientais. A pesquisa exploratória e descritiva utilizou a narrativa de história de vida de Tupi para expressar como as trajetórias de escolarização das mulheres amazônidas incluem ciclos de violência geracionais, abuso sexual, dificuldades econômicas, enfraquecimento de laços familiares e insegurança alimentar e habitacional. Tais obstáculos, somados à transição para o ensino superior em tempos de pandemia, configuram um panorama complexo e desafiador. Por isso, as políticas socioassistenciais, os projetos de extensão, intercâmbio, os vínculos com as professoras e colegas, os coletivos feministas e a conexão com a florestalidade amazônica foram fundamentais para a permanência e promoção da saúde integral.

RESEARCH ON CONSTRUCTION TECHNOLOGY OF LARGE-DIAMETER SHIELD TUNNEL IN SHALLOW COVER SECTION OF RED STRATA GEOLOGY
Authors: Zhang Kexin , Ouyang Jian , Wang Haijun , Dong Xin , Hu Dawei , Xue Xingwei 
Published: September 2024

This paper is based on the construction of the Haizhuwan Tunnel in Guangzhou, which passes through predominantly mudstone and sandstone red strata geology. Excavation is carried out using a slurry balance shield tunneling machine with both atmospheric pressure and pressurized cutterheads, and real-time excavation parameters recorded by the shield equipment are collected and statistically analyzed. Discovery: In the initial shallow-buried excavation section, the total thrust of the shield machine increased as the tunneling distance increased. By continuously adjusting the excavation parameters during construction, the shield machine gradually tended towards a stable operating state, leading to a gradual reduction in the range of thrust fluctuations. East Line: After excavating the reinforcement area, the increase in cutterhead torque is significant, leading to a more pronounced adaptation process for the shield machine. The cutterhead torque fluctuates more on rings 20 to 65 on the East Line, showing greater variability. This situation is related to the wear of the cutterhead and the condition of the shield machine equipment on the East Line. West Line: After excavating the reinforcement area, the cutterhead torque is initially reduced, with a slow and continuous increase in torque from rings 20 to 65, eventually stabilizing at around 12 MN·m. Throughout the excavation process, the shield machine on the East Line maintained a relatively high excavation speed within the reinforced soil at the face, with an average of 7.76 mm/min. As the machine excavated beyond the reinforcement area, the overall excavation speed of the shield machine slowed down. The excavation speed from ring 21 to ring 65 was primarily controlled between 2 to 6 mm/min, with an average of 4.49 mm/min, showing a relatively stable overall change.
Indigenousity in the empowerment of construction laborers: A case study of the Indonesian Construction Labour Union (SBKI) Gunung Kidul
Authors: Maulana Muhammad Husain 
Published: September 2024

This study aims to explore the role of local wisdom in the empowerment of construction laborers, focusing on the Indonesian Construction Labour Union (SBKI) in Gunung Kidul, using a qualitative approach. The findings show that these labor communities organically empower themselves through local traditions such as guys rukun and gotong royong, which not only build social solidarity but also strengthen labor organizations. Initiatives that emerge from within the community, both through labor rights advocacy and other empowerment activities, show that construction workers are able to utilize their local resources and potential to achieve welfare. This strong indigenousity within the community serves as important social capital in building organizational foundations, supporting advocacy processes, and empowering the community. The success of this empowerment initiative emphasizes the importance of respecting indigenousity in community development and demonstrates that communities can develop their own potential without the need for excessive external intervention. This indigenousity can ultimately serve as a model for other communities facing similar challenges.
Keywords: Local wisdom, Labour union, Community empowerment

LDCNN: A new arrhythmia detection technique with ECG signals using a linear deep convolutional neural network
Authors: Bayani Ali , Kargar Masoud 
Published: September 2024

AbstractThe electrocardiogram (ECG) is a fundamental and widely used tool for diagnosing cardiovascular diseases. It involves recording cardiac electrical signals using electrodes, which illustrate the functioning of cardiac muscles during contraction and relaxation phases. ECG is instrumental in identifying abnormal cardiac activity, heart attacks, and various cardiac conditions. Arrhythmia detection, a critical aspect of ECG analysis, entails accurately classifying heartbeats. However, ECG signal analysis demands a high level of expertise, introducing the possibility of human errors in interpretation. Hence, there is a clear need for robust automated detection techniques. Recently, numerous methods have emerged for arrhythmia detection from ECG signals. In our research, we developed a novel one‐dimensional deep neural network technique called linear deep convolutional neural network (LDCNN) to identify arrhythmias from ECG signals. We compare our suggested method with several state‐of‐the‐art algorithms for arrhythmia detection. We evaluate our methodology using benchmark datasets, including the PTB Diagnostic ECG and MIT‐BIH Arrhythmia databases. Our proposed method achieves high accuracy rates of 99.24% on the PTB Diagnostic ECG dataset and 99.38% on the MIT‐BIH Arrhythmia dataset.
The Yang–Mills–Higgs functional on complex line bundles: Asymptotics for critical points

Abstract
We consider a gauge-invariant Ginzburg–Landau functional
(also known as Abelian Yang–Mills–Higgs model),
on Hermitian line bundles over closed Riemannian manifolds of dimension

n

{n\geq 3}

.
Assuming a logarithmic energy bound in the coupling parameter, we study the asymptotic behaviour of critical points
in the London limit. After a convenient choice of the gauge, we show compactness of finite-energy critical points
in Sobolev norms.
Moreover, thanks to a suitable monotonicity formula, we prove that the energy densities of critical points,
rescaled by the logarithm of the coupling parameter, converge to the weight measure of a stationary, rectifiable varifold of codimension 2.

Mixed Hodge structures and Siegel operators
Authors: Ma Shouhei 
Published: September 2024

Abstract
In this paper, we study mixed Hodge structures on the cohomology of locally symmetric varieties and give an application to modular forms.
After proving vanishing of some Hodge numbers, we focus on the weight filtration on the last Hodge subspace of the middle degree cohomology.
We prove that the weight filtration coincides with the corank filtration on the space of modular forms of canonical weight defined by the Siegel operators, and calculate the graded quotients.
As an application, we deduce surjectivity of the total Siegel operators in many cases, and identify an obstruction space in the remaining case.
The Evolution of Entrepreneurial Opportunity: The Case of a Finnish Start-up in the Telecom Industry
Authors: Tuomisalo Teemu , Hannibal Martin 
Published: September 2024

Abstract
This study represents a longitudinal in-depth investigation of entrepreneurial opportunity development in a Finnish start-up company. A qualitative interpretive case study method is applied here that enables us to provide in-depth findings to promote opportunity-related research in the fields of entrepreneurship and International Entrepreneurship. We create an empirical process model that unlocks the longitudinal development of entrepreneurial opportunity and internal and external features contributing to it. The findings indicate that the development process represents a transformation from the assessment of demand into the creation of actual solutions. In addition, the process model reveals how the objectives and motivations of individuals, as well as external features in the industry and events, drive the development of entrepreneurial opportunity.

Published: September 2024

Abstract
This study presents a new approach for producing zinc oxide nanoparticles (ZnONPs) utilizing an emulsion of beta-cyclodextrin (β-CD) and Phyllanthus emblica fruit extract. When synthesized, the particles were around 90 ± 5 nm in size. The zeta potential investigation yielded a value of −27.1 mV. The generated ZnONPs exhibited 83.70% anti-oxidant activity as well as good radical scavenging capabilities. The catalytic activity of ZnONPs was investigated using rhodamine B dye, and they displayed that maximum photocatalytic degradation was found to be 90.32% when exposed to UV light and 50.5% when not exposed to UV light. The kinetic investigation of photocatalytic degradation employs pseudo-first-order rate kinetics, with a rate constant of 2.5 × 10−2 under UV irradiation and 1.1 × 10−2 without irradiation. Anti-bacterial tests against Escherichia coli bacteria demonstrated the particles’ anti-bacterial characteristics. Anti-cancer studies were carried out using KB-31 cancer cells at varying particle concentrations. The studies confirmed that the particles produced are anti-cancer. In conclusion, this study reports a new green synthesis method to fabricate ZnONPs with high anti-microbial, anti-oxidant, and anti-cancer properties and suitable for various biomedical applications.

The overdetermined Cauchy problem for the hyperbolic Gellerstedt equation
Authors: Rogovoy Alexander V. , Kalmenov Tynysbek S. , Kabanikhin Sergey I. 
Published: September 2024

Abstract
Overdetermined boundary value problems and the minimal operators generated by them are extremely important in the description of regular boundary value problems for differential equations, and are also widely used in the study of local properties of solutions. In addition, for inverse problems of mathematical physics arising from applications, when determining unknown data, it is necessary to study problems with overdetermined boundary conditions, which is reflected in the study of problems, including for hyperbolic equations and systems, arising in physics, geophysics, seismic tomography, geoelectrics, electrodynamics, medicine, ecology, economics and many other practical areas. Thus, the study of overdetermined boundary value problems is of both theoretical and applied interest. In this paper, a criterion for the regular solvability of the overdetermined Cauchy problem for the Gellerstedt equation and the minimal differential operator generated by it in a hyperbolic domain is established, as which both the case of a characteristic triangle and the case of a more general domain with fairly general assumptions about the boundary of the domain are considered. Due to overdetermined boundary conditions, the problem under consideration will be ill-posed in the general case, therefore, for its regular solvability, additional conditions must be imposed on the initial data. In other words, we have considered the inverse problem: to determine what requirements the initial data of the problem, in particular the right part of the Gellerstedt equation, should meet, in question, so that the overdetermined Cauchy problem is regularly solvable. The proof is based on the Gellerstedt potential, the properties of solutions of the Goursat problem in the characteristic triangle, and the properties of special functions.

. The devised scheme is a generalization of the existing schemes developed earlier. Further, we adopt the discussed scheme for solving a linear time fractional advection–diffusion equation and a nonlinear time fractional reaction–diffusion equation with Dirichlet type boundary conditions. We show that the discussed method is unconditionally stable, uniquely solvable and convergent with convergence order O(τ

Research Trends in Public Libraries as Public Spheres in Library and Information Science: Topic Modelling with Latent Dirichlet Allocation
Authors: Sugeno Yuki , Koizumi Masanori 
Published: September 2024

Abstract
Public libraries and public spheres have been widely studied over the past three decades. In recent years, several studies have comprehensively reviewed past research results to reveal the main issues, concerns, and research topics in the field of public libraries and public spheres. These studies have elucidated that the research theme of public libraries as a ‘meeting place’ has received increasing attention. They also noted the need for quantitative approaches in this field. Addressing this requirement, we conducted quantitative topic modelling using latent Dirichlet allocation and established an overview of research topics in the literature related to public libraries as public spheres. The following four periods emerged: first period (1993–2003), second period (2004–2010), third period (2011–2015), and fourth period (2016–2022). By analysing a cross-section of research topics from all periods, we elucidated the transitions of research themes developed in the research field. In addition, our comparison of topic model maps and topics over the years revealed that research topics appear to have become increasingly complex. Research topics on meeting places in public libraries have emerged continually and changed over time, covering (1) places for individual civic group activities, (2) public spaces where patrons face diversity and pluralism, (3) community spaces where patrons foster social trust, and (4) social spaces where patrons build social capital in the community. This result indicates that the research on public libraries as public spheres has gradually developed based on these venues being meeting places and will continue to progress.
Frequency and clinicopathological correlation of gastrointestinal polyps: A six-year single center experience
Authors: Abdulqader Goran Mohammed Raouf 
Published: September 2024

Abstract

Background
Most gastrointestinal polyps are asymptomatic; therefore, assessing symptoms associated with cancer and precancerous polyps is essential.

Objectives
The aim of this study was to study the histopathology, number, distribution, and degree of polyps’ dysplasia in terms of age, gender, and clinical presentation.

Methods
This study was performed on patients who underwent endoscopy from July 2015 to August 2021 in Sulaimaniyah, Iraq. Surgical pathology records of patients were analyzed for age, sex, nature of the polyps, number, site, histopathology, degree of dysplasia, resection margins and patients’ presented clinical data.

Results
The mean patients’ age was 51.4 ± 17.1 years, and most were males (51.9%). The most common indications for endoscopy were screening (28.62%), and the least common was weight loss (4.46%). Neoplastic polyps were common among patients with hematemesis (75%), while non-neoplastic were common among those with dyspepsia (60%). Most polyps were solitary in upper (80.8%) and lower gastrointestinal tract (GIT). Most polyps in the upper GIT were non-neoplastic (87.3%), while most lower proximal/distal GIT polyps were neoplastic. Most neoplastic polyps showed low-grade dysplasia (94.4%), and most high-grade dysplasia was a villous type (24.1%).

Conclusions
Initiation of the screening program is highly recommended as a facilitating method for the early detection of multiple and high-grade gastrointestinal polyps. Thus, screening programs can reduce the rate of mortality of carcinoma in this locality.
