With the growing demand for fast and reliable communication systems, particularly in outdoor environments, it is essential to investigate advanced encoding techniques. Digital Pulse Interval Modulation (DPIM) and Dual Header Pulse Interval Modulation (DHPIM) emerge as promising alternatives to traditional line coding methods, providing enhanced spectral efficiency and resistance to signal disruptions. This paper presents the performance of a Quadrature Phase-Shift Keying (QPSK) Orthogonal Frequency Division Multiplexing (OFDM)-based Optical Wireless Communication (OWC) system using these advanced encoding schemes. The analysis includes simulation results on QPSK-OFDM-based transmitter design, free space optical channel modeling based on Gaussian and log-normal distribution atmospheric turbulence, and recovery of input digital stream using the mentioned line coding techniques. The results demonstrate optimal bit error rate (BER) values for the QPSK-OFDM-based OWC system. The primary innovation of this research lies in the encoding schemes and their performance in outdoor optical wireless communication systems under turbulent conditions. Through extensive simulations and analysis, detailed insights into the bit error rate and outage throughput characteristics of DPIM/DHPIM coded QPSK-OFDM are provided, offering a unique perspective on the performance of these schemes in real-world scenarios. The findings not only highlight the optimal BER values achievable with the QPSK-OFDM-based OWC system but also offer insights into the system's ability to overcome transmission challenges under various atmospheric conditions.
Perceptions of the Use of Mobile Technologies for Smoking Cessation: Focus Group Study With Individuals of Low Socioeconomic Status Who Smoke
Authors: Wakeman Michael , Tesfaye Lydia , Gregory Tim , Leahy Erin , Kendrick Brandon , El-Toukhy Sherine
Published: October 2024

Background

The use of mobile technologies to deliver behavioral health interventions, including smoking cessation support, has grown. Users’ perceptions are important determinants of the adoption and use of new technologies. However, little is known about users’ perceptions of mobile technologies as smoking cessation aids, particularly among disadvantaged individuals who smoke.

Objective

This study aimed to examine the acceptance of mobile technologies for smoking cessation among young adults with low socioeconomic status who smoke.

Methods

In total, 38 current cigarette smokers, 18 to 29 years old, who wanted to quit and did not have a 4-year college degree nor were enrolled in a 4-year college, participated in 12 semistructured digital focus groups. The moderation guide was guided by the Unified Theory of Acceptance and Use of Technology. Discussions were audio recorded, transcribed verbatim, and coded for the Unified Theory of Acceptance and Use of Technology constructs (ie, effort expectancy, facilitating conditions, performance expectancy, and social influence), sentiment (ie, negative, neutral, and positive), and purpose of using mobile technologies (ie, lifestyle and health management and smoking cessation) following a deductive thematic analysis approach.

Results

Participants had positive experiences using mobile technologies for lifestyle and health management, primarily for fitness and dietary purposes. Salient themes were facilitating conditions of use (44/80, 55%), with prior experiences and costs subthemes, followed by perceived usefulness of mobile technologies in helping users attain health goals (22/80, 27.50%), which were generally positive. Ease of use (11/80, 13.75%) and social influences (3/80, 3.75%) were minimally discussed. Conversely, participants had limited awareness of smoking cessation uses of mobile technologies, which was the primary barrier under facilitating conditions discussed (33/51, 64.70%). Participants expressed skepticism about the usefulness of mobile technologies in helping them quit smoking (14/51, 27.45%). Effort expectancy was not discussed, given participants’ limited prior use. Social influences on mobile technology use for smoking cessation were minimally discussed (4/51, 7.84%).

Conclusions

The use of mobile technologies for smoking cessation was unknown to young adults with low socioeconomic status who smoke. To reduce cigarette smoking and associated health disparities, increasing awareness and use of evidence-based mobile-based smoking cessation interventions are needed. Smoking cessation interventions should incorporate features perceived as useful and easy to use to capitalize on positive user experiences and the acceptability of mobile technologies for lifestyle and health management.

Published: October 2024

Key Points

Primary FSGS is a rare immune mediated glomerulopathy that accounted for 16.6% for all FSGS reported biopsies among a diverse patient population.

From 2010 to 2021, the standardized incidence of primary FSGS was estimated at 1.7 cases per 100,000 patient-years.

The highest incidence of primary FSGS was observed among Black (3.2) and Asian (2.7 cases per 100,000 patient-years) people.

Background

Focal segmental glomerulosclerosis (FSGS) refers to a pattern of glomerular injury but also includes primary FSGS which is considered as an immune-mediated glomerulopathy. We sought to determine the incidence of primary FSGS and proportion of patients with FSGS who have primary FSGS among a large diverse patient population in the United States.

Methods

A cross-sectional study (2010–2021) was performed within an integrated health system in patients (age 18 or older) with biopsy-proven FSGS. Among biopsies with FSGS as the first diagnosis on pathology report, chart reviews were performed to determine primary FSGS, defined as podocyte foot process effacement ≥80% on electron microscopy. The proportion of patients with primary FSGS and annual incidence rate (IR) (per 100,000 patient-years) were calculated. Standardized IR were determined by age, sex, and race and ethnicity based on US population structure of the 5-year (2018–2022) American Community Survey estimates.

Results

We identified 3838 patients with FSGS reported on biopsy. Among 1502 with FSGS as the principal diagnosis, 637 met criteria for primary FSGS (mean [SD] age 55.5 years [17.9], 56.5% male, 35.6% Hispanic, 28.7% White, 17.9% Asian/Pacific Islander, and 16.0% Black). The mean standardized IR (confidence interval) of primary FSGS was 1.7 (0.9 to 2.5) per 100,000 patient-years during the study period. The standardized annual IR ranged from 1.3 to 2.4 per 100,000 patient-years. IR (per 100,000 patient-years) were highest among Black (3.2), Asian (2.7), and Pacific Islander (2.8) patients.

Conclusions

Primary FSGS accounted for 16.6% of biopsy-proven FSGS. Primary FSGS is a likely a rare disease with incidence highest among Black, Asian, and Pacific Islander people. More precise identification of primary FSGS may facilitate work to improve understanding of this glomerulopathy and improve kidney outcomes.

Moment Curvature and P-M Interaction Analysis of Steel and GFRP Reinforced Concrete Column
Authors: Kumar Olipilli Dinesh
Published: October 2024

This research explores the use of Glass Fiber Reinforced Polymer (GFRP) bars and GFRP circular sections as longitudinal reinforcement in Reinforced Concrete (RC) columns, specifically to mitigate corrosion issues in harsh coastal environments. Twelve concrete specimens were prepared and tested under various loading conditions to evaluate the performance of GFRP as a substitute for conventional steel reinforcement. The experimental findings indicated that GFRP-RC columns displayed slightly lower axial load and bending moment capacities compared to steel-RC columns, though the ductility of both types was found to be similar. The study also highlights the significance of considering the role of GFRP bars in compression, supported by experimental results. This research offers valuable insights into the behavior and performance of both steel and GFRP-reinforced concrete columns, particularly in environments vulnerable to corrosion, with assessments conducted at 28 and 60-day intervals. A comparison of the outcomes from these timeframes reveals the effectiveness of GFRP as a reinforcement option in corrosive conditions

Authors: Ali Ali Mumdin , AM Soma  , Ramayuli
Published: October 2024

MSMEs play a significant role in supporting the country's economy as they account for 60.5% of GDP. MSMEs confront a number of difficulties related to financing, supply, and market demand that need to be given more consideration in order to support their entry into the global market. The purpose of this study is to examine how government involvement, technology advancement, human capital investment, and entrepreneurial orientation affect MSMEs (micro, small, and medium-sized firms) in Indonesia and their internationalization strategies. This study uses a quantitative approach with data collection techniques using a Likert scale questionnaire. Then descriptive analysis and Partial Least Squares (PLS) are used to analyze the data. The study's findings show that technical change significantly affects MSMEs' internationalization strategies; in contrast, entrepreneurial orientation, investments in human capital, and the role of the government are not as significant in this regard. However, this research offers stakeholders improved guidance for bolstering MSMEs' success and expansion in global markets, as well as for widening the gap in the global MSME market to promote Indonesia's sustainable economic growth.

Aim/purpose – Aside from conventional debt financing, mezzanine debt funding is an essential, nontraditional, and innovative instrument for financing a corporation. Nonethe- less, the use and discussions on this particular type of financing are still limited. This study aims to investigate the nature and patterns of mezzanine debt financing and agreements at the global and regional levels, seeking to understand the trends and differ- ences in its funding flows and deal movements across various continents so that busi- nesses looking to grow abroad might use this analysis to identify places where mezza- nine finance is more accessible or advantageous. Moreover, investors can select the most appealing markets and conditions for mezzanine investments, thus improving their port- folios. Design/methodology/approach – Using seven global regions (e.g., Asia, Africa, Eu- rope, Middle East, North America, Oceania, and rest of the world (RoW)) annual data from 2006 to 2023, this study employs descriptive analysis and applies the one-way between groups ANOVA. Findings – The findings show notable differences in the flows of mezzanine debt fund- ings and deals across different geographical locations globally. Besides, it also explores that mezzanine debt financing and agreements in North America and Europe make up most of the contributions, while other regions are still at the early stage of development. Research implications – Policymakers and governments in regions like Asia, Africa, the Middle East, Oceania, and the RoW should look into ways to increase the flow and growth of their agreements because the patterns and trends of funding and deals in those regions are considerably lower than North America and Europe. Originality/value/contribution – The literature on mezzanine debt mainly addresses its definition, features, facilities, disadvantages, and possible borrowers. This study investi- gates the recent pattern and trend of mezzanine debt funding and its deals globally based on different geographical locations. Keywords: mezzanine, mezzanine financing, mezzanine debt, mezzanine deals. JEL Classification: D24, G11, H63.

Authors: Pozdnyakova E. A.
Published: October 2024

The subject of the study is doctrinal research and legislative norms that form and consolidate the definition of land management in the period from 1917 to the present. The basis for the study is the low legislative technique of the draft law “On Land Management” being developed today, the lack of re-evaluation of the definition of land management. Since the legal regulation of the institute of land management cannot be effective without a basic concept, it is advisable, using the historical method, to analyze the existing definitions of land management, to determine its stable elements that could be applied when developing a new draft law.

Published: October 2024

Soldiers get rescue services through static wireless node heliports and medical ambulance to provide special service, in a battle field. The Mobile Ad hoc Network environment takes wireless communication across border communication to connects the source of multiple serves in military applications. The mobile node acts as mobile equipment to rescue the soldier.  Due to increasing delay tolerance and latency overhead the performance eon network is degraded, to resolve this problem , this paper concentrates on Region and Mobility based Route Request Processing in AODV (RMRRP) is proposed in controlling Route Request Processing mechanism based on node mobility for reducing the routing overhead in AODV. The routing algorithm which guarantees services to the soldier in a shortest time also evaluate the energy efficiency of RMRRP with the existing AODV, DSDV, DSR routing algorithms. Efficiently reduce the overall overhead to a considerable level and significantly improve the overall performance by finding a rectangular region as a forwarding zone and only the nodes within the rectangular region are allowed to forward the RREQ message from source to the destination, hence the overhead in establishment of a stable shortest path gets reduced very much. Network region is minimized. Routing request packets generated is less and route request is reduced. Region width is limited to 150m and within that covered area only route discovery and route maintenance is carried out. Control packets are reduced within the limited rectangular region and data packets are able to send more. Avoiding link breaks to send and receive more data packets with a limited number of control packets hence consumes considerable energy. Simulation result reveals that with nodes 50 the Packet delivery Fraction is 90.60 , Routing overhead is 11376, Normalized Routing Load is 3.61 , Throughput is 261.94Kbps, MAC Load is 39.17 , Energy consumption is 4.64 Joules.

Authors: Moura Pamella , Nauter Gustavo Esteves , Kubrusly Regina , Pereira Mauricio Santos
Published: October 2024

O uso de drogas no Brasil, lícitas e ilícitas, é um grave problema de saúde pública. O III Levantamento Nacional sobre o Uso de Drogas revela que 66,4% dos brasileiros entre 12 e 65 anos já consumiram álcool, e 33,5% já usaram tabaco, com alta prevalência entre adolescentes. Além disso, 15 milhões de indivíduos admitiram o uso de drogas ilícitas. Entretanto, o uso, abuso e dependência de drogas, apesar de frequentemente usados como sinônimos, têm definições distintas. O consumo abusivo pode evoluir para o Transtorno de Uso de Substâncias (TUS), que envolve a perda de controle sobre o consumo e a compulsão pela droga. Fatores genéticos, ambientais e as características da substância influenciam na vulnerabilidade ao vício. Este artigo discute a neuroquímica das drogas de abuso, destacando o papel da dopamina e do sistema de recompensa no desenvolvimento da adicção, além de discutir três das principais drogas utilizadas no Brasil, o álcool, a nicotina e a cocaína/crack. A compreensão desses mecanismos é essencial para enfrentar os desafios associados ao consumo de drogas no Brasil.

Metacognição em humanos
Authors: Coutinho Bruna , Filgueiras Cláudio , Landeira-Fernandez Jesus , Eichenberg Krahe Thomas
Published: October 2024

A metacognição é a capacidade de refletir sobre o próprio pensamento, englobando o processo cognitivo de avaliar, monitorar e regular a própria cognição. Essa habilidade é fundamental para o aprendizado eficaz e para o desenvolvimento de uma autoconsciência sofisticada. A evolução do cérebro humano, com seu aumento significativo em tamanho e complexidade, forneceu a base neurológica para o desenvolvimento avançado da metacognição, permitindo a emergência de capacidades cognitivas superiores como a autorregulação e a reflexão sobre o próprio pensamento. Este artigo explora a evolução humana com foco em marcos filogenéticos que contribuíram para o desenvolvimento da autoconsciência, buscando compreender as características únicas que nos diferenciam como espécie. Argumentamos que a metacognição não é apenas uma função individual, mas também é profundamente influenciada por pressões sociais e culturais. A necessidade de lidar com dinâmicas sociais complexas pode ter impulsionado o desenvolvimento de habilidades metacognitivas, permitindo a avaliação e regulação do próprio comportamento e dos estados mentais. Analisamos também a interdependência entre metacognição e teoria da mente e como essa relação evoluiu ao longo da história humana. Compreender essa relação pode esclarecer o surgimento dessas capacidades e sua importância para a adaptação social. Portanto acredita-se que o estudo da metacognição e suas raízes evolutivas oferece conhecimentos valiosos sobre o comportamento humano.
Impactos da cafeína no sistema nervoso central

Published: October 2024

A cafeína é a substância psicoativa mais consumida no mundo e seu consumo está associado às suas propriedades estimulantes, mas seus efeitos variam dependendo da dose e da fase do desenvolvimento. Nessa revisão, iremos abordar os efeitos da ingestão indireta de cafeína nos períodos de gestação e lactação, e os efeitos diretos após consumo na infância, adolescência ou no adulto. O consumo de cafeína no período gestacional pode levar a maior risco de aborto, retardo no crescimento intrauterino, menor peso do recém-nascido, dentre outros efeitos. A ingestão de cafeína durante a lactação, na infância ou na adolescência levam a efeitos a curto e longo prazo, podendo se estender até a fase adulta. Nestes casos, observa-se alterações comportamentais relacionadas a efeitos ansiogênicos com desregulação do eixo hipotálamo-hipófise-adrenal e prejuízos cognitivos. Alterações em proteínas sinápticas e na neurotransmissão GABAérgica também são descritas. Por outro lado, o consumo de cafeína é maior na fase adulta. Trabalhos realizados com modelos animais e com humanos têm demonstrado efeitos positivos do consumo nesta fase, especialmente levando a melhoras cognitivas, aumento de sítios sinápticos tanto em condições normais quanto em doenças neurodegenerativas como o Alzheimer. Em conjunto, estes dados apontam para a importância de alertar a população sobre os possíveis efeitos negativos do consumo de cafeína em etapas precoces do desenvolvimento, mas também trazem a possibilidade de utilizá-la como coadjuvante terapêutico para produzir melhoras cognitivas no adulto, no idoso e em pacientes com déficits cognitivos.
Fome e as formas ocultas de desnutrição
Authors: Serfaty Claudio Alberto
Published: October 2024

A desnutrição crônica e a fome são ameaças ao pleno desenvolvimento cerebral com grande potencial para comprometer gerações futuras, já que podem produzir impactos no desenvolvimento cerebral. Por este motivo, a desnutrição  grave  a fome constituem uma emergência de saúde pública, amplamente relacionada à mortalidade infantil e que necessita de pronta ação do poder público. Mas para além dos fatores visíveis da desnutrição nosso grupo chamou a atenção para formas mais sutis que se apresentam com pequenas (ou nenhuma) alterações de padrões antropométricos. Estamos falando de formas ocultas de desnutrição provocadas pela carência nutricional de nutrientes essenciais, ou seja, aqueles que dependem exclusivamente da dieta:  o aminoácido triptofano e os ácidos graxos ômega-3. Neste artigo vamos rever os conceitos de refinamento de circuitos neurais e períodos críticos do desenvolvimento a partir de estudos em modelos animais, incluindo as interações neuroimunes reveladas nos últimos anos. Também vamos rever os estudos que mostram que a desnutrição de nutrientes essenciais, pode causar sérios impactos no desenvolvimento do sistema nervoso central com repercussões sobre distúrbios do desenvolvimento como o TEA, a esquizofrenia, ou mesmo déficits de aprendizagem observados em crianças neurotípicas.
Desafios na Implementação da Educação Patrimonial na Assistência Estudantil:
Authors: Luzes Jessica Suzano
Published: October 2024

Como as universidades contribuem para a educação patrimonial em um país? São instituições sociais que formam profissionais nas áreas de história, conservação, restauração, entre outros, mas para além do compromisso com as especificidades destas variadas áreas de saber, pretende-se enfocar o desenvolvimento integral do estudante. Esse enfoque se fundamenta no amplo debate sobre a inclusão da cultura e sua diversidade como um dos objetivos do desenvolvimento sustentável (ODS), um desafio que atravessa diferentes áreas das políticas públicas, como evidenciado na meta 4.7, que associa a educação inclusiva e equitativa de qualidade ao acesso aos bens culturais.
Nesse contexto surge o projeto "Trajetos Culturais", realizado pela Pró-reitoria de Políticas Estudantis (PR7) da Universidade Federal do Rio de Janeiro (UFRJ). Esse projeto oferece visitas guiadas a espaços culturais para estudantes de graduação e pós-graduação, muitos dos quais em situação de vulnerabilidade socioeconômica. O foco está na análise histórica desse projeto, realizado entre 2018 e 2023, coordenado pela equipe multidisciplinar da Divisão de Esporte, Cultura e Lazer (DECULT) PR7/UFRJ. Parte-se de uma análise ex-ante que considera o contexto das políticas no âmbito da assistência estudantil, o desenvolvimento de um projeto experimental no âmbito da cultura, o "Ônibus cultural". A análise ex-post se apresenta em resultado e discussões, que possibilitam resultados e impactos concretos, tendo como referência as diretrizes da educação patrimonial do Brasil, conforme a portaria nº 137, de 28 de abril de 2016.  Ambas as formas de avaliação (prévia e posterior) envolvem uma análise exploratória de variáveis qualitativas registradas nos formulários de inscrição dos participantes, todos analisados por meio de técnicas de Data Science Analytics. Como considerações finais, assinala-se os feedbacks dos participantes dessas ações.

O objetivo desta pesquisa foi avaliar as abordagens pedagógicas utilizadas no processo de ensino-aprendizagem relacionadas a Educação Patrimonial. Realizou-se um estudo bibliométrico por meio do indexador de pesquisas Google Acadêmico. Buscou-se pesquisas que abordassem de alguma forma, a Educação Patrimonial. As palavras-chave utilizadas foram: (1) “práticas pedagógicas” e (2) “educação patrimonial” e (3) “estratégia de ensino” entre os anos de 2010 a 2022. Ao todo, foram selecionadas 28 pesquisas. Para o estudo bibliométrico foi identificado: nome dos autores; ano de publicação; tipo de pesquisa; área de conhecimento; instituição e práticas pedagógicas que foram adotadas. A priori, destaca-se o baixo fluxo de pesquisas que apresentam as práticas pedagógicas, no entanto, as utilizadas favoreceram no processo de ensino e aprendizagem, tornando-o mais eficaz e satisfatório tanto para os professores, quanto para os alunos. A área de história foi a mais representativa. Entre os tipos de pesquisas, as dissertações se destacaram em quantidade. Em grande parte dos estudos foi possível constatar que o patrimônio foi visto como meio, e os principais agentes do processo foram os sujeitos e suas experiências, contribuindo com o ambiente escolar e para além da escola na ressignificação do patrimônio cultural.

A dimensão educativa ocupa hoje um espaço relevante nas práticas artísticas, não apenas como elemento complementar ou prática secundária, mas como chave para a produção de conhecimento e para o trabalho das políticas culturais. Os modelos educativos que estão a ser desenvolvidos nos museus e centros de arte espanhóis representaram uma mudança de paradigma. Neste sentido, cada vez mais instituições culturais estão a dotar os seus projectos de aspectos artísticos dos programas educativos, com o objectivo de tornar as propostas expositivas e os recursos utilizados para a sua definição mais compreensíveis e acessíveis a todos os tipos de públicos, cujos um produto educativo aumentaria, por sua vez, o interesse do turismo cultural. Palavras-chave: história da arte; património cultural; museologia; gestão cultural; mercado da arte.

Apresentamos reflexões sobre uma atividade de museologia social concebida e realizada na praia de Atafona, no litoral norte do estado do Rio de Janeiro, pelo Grupo Erosão, com produção da CasaDuna – centro de arte, pesquisa e memória de Atafona. As reflexões se dão a partir de uma pesquisa no campo do patrimônio, tentando pensá-lo para além de sua materialidade, nas relações entre o território e as práticas culturais. Em uma perspectiva crítica às matrizes epistêmicas euro-centradas aplicadas ao campo da cultura, analisamos uma experiência de museologia social que ensaia e enseja novos modos de ação local e de pesquisa ambiental.
