Published: December 2024

Quality assurance is a critical aspect in the production systems, affecting product quality and safety. Defects and failures of manufactured components will diminish overall product quality, which could vulnerably risk consumer safety. This study focuses on quality assurance analysis of train component manufacturing systems. According to the quality control data, the number of defects recorded was about 10-12, on average, for each wagon produced. The defect mainly occurred while making the underframes, car body, and even the small components. This led to the tardiness of product delivery for 1-2 months. This study aims to analyze non-conformance report data and identify the potential failure modes, potential effects, and root causes. To do so, we integrated systematically FMEA (Failure Mode and Effect Analysis) and FTA (Fault Tree Analysis). First, RPN (Risk Priority Number) score was calculated to determine risk priority. Second, Pareto analysis was performed to select defects that most contributing to overall failures, which were then analyzed using FTA to obtain root causes. The results show that 8 defects exceed the critical RPN score of 209. Materials and personnel are identified as two major contributor failure events from three selected defects. The recommendation for further improvements is provided based on various defect categories to prevent similar defects. The findings demonstrate that the combined use of FMEA and FTA is effective in identifying failures and root causes within complex and long production cycle systems.

Published: December 2024

Data Envelopment Analysis (DEA) is a method considered to evaluate a company's performance. DEA applies multiplies the input and output variables for analyzing the efficiency but does not provide guidance in selecting those variables. As a rule, researchers use several methods. If the number of variables used is too many, it will affect the efficiency value. This will reduce the strength of the efficiency value, which can cause all DMU values to be efficient. DEA and variable selection are important in performance evaluation because DEA aids in determining relative efficiency, whereas variable selection guarantees that the evaluation is based on the most relevant and significant aspects. The purpose of this study is to suggest the variable combination method for subtracting the number of variables that will be utilized in implementing the DEA. The method used in this study is the Average Input Variable Combinations (VCs)-Variable Returns-to-Scale (VRS) DEA. The data were classified, defined, and processed with a view to computing efficiency scores and DMU classifications. The research result indicated that the proposed method (VCs-DEA) treats the variable reduction factor and the average calculation factor to obtain the final result of the efficiency score. These two factors contribute to the accuracy of the efficiency value. Some real-world implications of these findings, such as making better use of resources, streamlining operations, and coming up with new plans, Furthermore, the evidence may be used to benchmark performance as well as help decision-makers in creating more effective policy. This study finds that only 1 out of 12 DMUs is efficient (8%), while the remaining 11 are inefficient (92%). Indonesia quarrying establishment can be classified into 3 categories such as Optimal Category (S-Sand); Middle Category (LS-Lime-Stone; F-Feldspars; Gr-Granite; SA-Stone and Andesite; K-Kaolin; Q-Quartz; and G-Gravel); and Less Category (So-Soil; C-Clay; M-Marble; and O-Others).

Authors: Grigoriev F. V. , Sulimov V. B. , Kutov D. C. , Tikhonravov A. V. 
Published: December 2024

The previously developed method of atomistic modeling of physical vapor deposition is applied to study the structural properties of Ta2O5 films. For the first time, to the best of our knowledge, the structural parameters of these films are calculated using atomistic clusters with technologically significant dimensions. It is found that low-energy deposition results in the formation of a low-density transition region between the substrate and the films. High-energy deposition results in the growth of a homogeneous structure without pores with a characteristic size of more than 0.1 nm. The density of low- and high-energy deposited films is lower than the density of the bulk amorphous sample. Reducing the deposition energy results in the formation of pores that can adsorb small molecules. The average coordination numbers of Ta and O atoms remain practically constant with decreasing deposition energy.

Authors: Teng Jinlin , Zhang Cheng , Gong Huimin , Liu Chunqing 
Published: December 2024

The evaluation of urban noise suitability is crucial for urban environmental management. Efficient and cost-effective methods for obtaining noise distribution data are of great interest. This study introduces various machine learning methods and applies the Random Forest algorithm, which performed best, to investigate noise suitability in the central urban area of Nanchang City. The findings are as follows:
1.Machine learning algorithms can be effectively used for urban noise evaluation. The optimized model accurately reflects the noise suitability levels in Nanchang City.
2.The feature importance ranking reveals that population spatial distribution has the most significant impact on urban noise, followed by distance to water bodies and road network density. These three features significantly influence the assessment of urban noise suitability and should be prioritized in noise control measures.
3.The weakly suitable noise areas in Nanchang’s central urban region are primarily concentrated on the east bank of the Ganjiang River, making this a key area for noise management. Overall, the Unsuitable, Slightly suitable, Moderately suitable, Relatively suitable, and Height suitable areas constitute 9.38%, 16.03%, 28.02%, 33.31%, and 13.25% of the central urban area, respectively.
4.The SHAP model identifies the top three features in terms of importance, showing that different values of feature variables have varying impacts on noise suitability.
This study employs data mining concepts and machine learning techniques to provide an accurate and objective assessment of urban noise levels. The results offer scientific decision-making support for urban spatial planning and noise mitigation measures, ensuring the healthy and sustainable development of the urban environment.

Introduction
Time-limited trial (TLT) is a structured approach between clinicians and seriously ill patients or their surrogates to discuss patients’ values and preferences, prognosis, and shared decision-making to use specific therapies for a prespecified period of time in the face of prognostic uncertainty. Some evidence exists that this approach may lead to more patient-centered care in the intensive care unit; however, it has never been evaluated in the emergency department (ED). The study protocol aims to assess the feasibility and acceptability of TLTs initiated in the ED.

Methods and analysis
We will conduct a parallel group, clinician-level, pilot randomized clinical trial among 40 ED clinicians. We will measure feasibility (e.g., the time it takes to conduct the TLTs by ED clinicians) and clinician and patient-reported acceptability of the TLT, and also track patients’ clinical outcomes via medical record review.

Discussion
This study protocol will investigate the potential of TLT initiated in the ED to lead to patient-centered intensive care utilization. By doing so, the study intends to improve palliative care integration for seriously ill older adults in the ED and intensive care unit.

A survey of knowledge and attitudes towards antibiotic use and resistance among teachers in the Republic of Kenya: Implications for using teachers in raising public awareness of rational antibiotic use in school communities
Authors: Mutua Patrick M. , Mutiso Joshua. , Gicheru Michael M. 
Published: December 2024

Background
Antimicrobial resistance is a significant public health threat. In Kenya, schools are targeted for public education to promote knowledge and attitudes towards the proper use of antimicrobials. However, there are limited studies that have investigated teachers’ knowledge and attitudes on antibiotic use.

Methods
We conducted an online survey from December 2023 to January 2024 which included 608 primary and secondary school teachers, representing a response rate of 93% of the estimated sample size of 653 teachers. Data on the respondents’ antibiotic knowledge score (seventeen questions) and attitude score (eleven questions) were analysed using IBM SPSS (Version 27). A binary logistic regression model was applied to analyze predicators of adequate knowledge and attitude on antibiotics.

Results
The average knowledge score for antibiotic use was 9.2 out of 17. Among the sampled teachers, 82% had not received public awareness information on proper antibiotic use. More than 86% of the respondents incorrectly answered that antibiotics are effective against colds. The average attitude score on antibiotic use was 6.1 out of 11. A quarter of the interviewees agreed that they gave family members antibiotics wherever they fell sick. Respondents aged 40–49 years and teaching in secondary school had higher odds for adequate knowledge in antibiotic use.

Conclusions
This study has identified significant knowledge and attitude gaps that need to be addressed by policy makers to ensure rational antibiotics use among teachers and in ensuring effective use of teachers in raising awareness in school communities for rational antibiotic use.
O ENSINO DA POESIA EM LIBRAS ATRAVÉS DAS ESTRATÉGIAS DE PEDAGOGIA SURDA
Authors: Sutton Spence Rachel , De Araujo Machado Fernanda , Hidalgo Pedroni Victória 
Published: December 2024

Este artigo tem por objetivo analisar maneiras de ensinar adultos surdos a criar poesia em língua de sinais como contribuição à pesquisa sobre escrita criativa no campo da língua de sinais. As pesquisas sobre a escrita criativa no Brasil ainda são escassas (Abed, 2021) e na área de Libras, não encontramos nenhum registro sobre o ensino da poesia em Libras para adultos. Como base teórica, destacamos a teoria acerca da pedagogia surda de Ladd e Gonçalves (2011). Ao considerar as formas de aprendizagem dos surdos, descrevemos a eficácia do uso de um poema específico num curso de extensão sobre poesia em Libras ocorrido na Universidade Federal de Santa Catarina. O curso foi ministrado por duas professoras surdas para adultos surdos, fluentes em Libras, que desejavam aprender sobre sua própria forma artística de linguagem cultural. Analisamos o poema Tree (Árvore), do poeta surdo britânico Paul Scott, destacando seus recursos poéticos, como um modelo para ensinar poesia em língua de sinais. Mostramos os resultados poéticos atingidos ao utilizar este poema num espaço de aprendizagem composto por professores fluentes e participantes surdos.
Blood Run Beech Read: Human–Plant Grafting in Kim de l’Horizon’s Blutbuch
Authors: Pahl Katrin 
Published: December 2024

Abstract
This article discusses human–vegetal bonds in Kim de l’Horizon’s award-winning novel Blutbuch. With its transgender perspective informing the text’s botanical imaginary Blutbuch holds, the author maintains, an irreplaceable position in the ecological or phytographic literature. The autofictional tale develops a unique non-binary poetics by creatively working through the impact of individual, arbitrary, and, most importantly, structural violence in the blood family on the coming-of-age and growing-into-a-body of its first-person narrator. “Blood Run Beech Read” explores how de l’Horizon confronts psychic trauma and how human–vegetal bonds and attention to the material language of plants help to disengage from the transgenerational patterns of its reproduction. Suggesting that trans* realities model a different relation to the un/natural: one that dares to forge so far unseen or unintelligible connections, the analysis focuses on human–plant grafts. Specifically, it considers the symbiosis and sympoiesis of beech tree and narrator/protagonist. Through creative translations and careful close readings of the grafting scenes in the autofictional text, “Blood Run Beech Read” argues for the materiality of language as constitutive of transcorporeality.
Hegel’s Theory of Time
Authors: Gentry Gerad 
Published: December 2024

Abstract
While sharing some features in common with presentist accounts of time, Hegel’s theory of time fundamentally offers an alternative to standard A-Theories, B-Theories, and C-Theories of time. While compatible with Kantian ideality of time on the one hand and spacetime in the theory of general relativity on the other, Hegel’s theory of time reaches beyond both a transcendental form of sensibility on the one hand and a paradigm for material motion in physics, on the other. Further, while Hegel’s theory of time provides reason to reject such theories of time as the Moving Spotlight, Growing and Shrinking Block, and a range of others, my interest here is in making comprehensible Hegel’s theory of time itself. I will argue that according to Hegel’s theory, the past and the future exist as constitutive of the now, and the now is not separable from space, but rather is itself spatial becoming. Stemming from his underlying logic of actuality and becoming, Hegel espouses the view that history (the past) and future possibility are present and constitutive of the “now.” Understanding his theory of time will also help shed some light on a systematic feature found across his philosophy of nature and mind. Additionally, while his theory presents an elegant notion of time within his philosophy, it also offers an intuitive and productive solution for a traditional identity problem of concrete particulars across time and intervenes in contemporary philosophy of time.
UMBUZEIRO DOS DEFUNTOS: UM MARCO NA HISTÓRIA DE SÃO LOURENÇO DO PIAUÍ

Published: December 2024

Resumo: O presente relatório refere-se a uma pesquisa que se faz junto ao umbuzeiro dos defuntos, marco histórico do município de São Lourenço do Piauí. Sabe-se pela história oral que, próximo a um frondoso umbuzeiro, foram enterrados muitos índios que não aceitaram ser escravos nas fazendas da região Sudeste do Piauí. Formula-se a hipótese de que ali foram sepultados quase quinhentos índios assassinados pelos portugueses na segunda metade do século XVII, conforme relato do padre Martinho de Nantes. Entrevistaram-se pessoas idosas da cidade de São Lourenço para resgatar fragmentos da tradição oral a respeito do umbuzeiro dos defuntos e da origem da atual cidade de São Lourenço. Não se encontraram informações da hecatombe narrada pelo missionário franciscano, porém, indicativos de que ali jazem os corpos de muitos índios mortos em situação de extremo desespero. Diz-se que o alto stress vivido no instante de seu assassinato se conserva e se manifesta em assombrações que se traduzem, regionalmente, como aleivosias. Espera-se que, com a abertura de sondagens e escavações, encontrem-se restos orgânicos e da cultura material que corroborem a hipótese que se formula no estágio atual da pesquisa.Abstract: This article refers to research that is done by the umbuzeiro dos defuntos, landmark of the municipality of São Lourenço do Piauí. It is known by the oral history that, next to a leafy umbuzeiro were buried many Indians who refused to be slaves on the farms of southeastern Piauí State. On formulates the hypothesis that there were buried nearly five hundred Indians killed by the Portuguese in the latter half of the seventeenth century, as reported by Priest Martin de Nantes. Interviews were conducted with elderly people in the city of São Lourenço to rescue fragments of oral tradition about umbuzeiro dos defuntos and the origin of the present city of São Lourenço. Information did not match the catastrophe narrated by Franciscan missionary however indicate that there lie the bodies of many dead Indians in a state of utter despair. It is said that the high stress experienced at the time of his murder is preserved and manifested in hauntings that translate regionally as aleivosias. It is hoped that with the opening of polls and excavations, meet organic remains and material culture to corroborate the hypothesis that on formulates in the current stage of research.

A PROBLEMÁTICA DOS CORTIÇOS PELOTENSES ENTRE OS SÉCULOS XIX E XX
Authors: Maciel Letícia Nörnberg 
Published: December 2024

Resumo: O presente artigo trata da formação, expansão urbana e o surgimento dos cortiços no século XIX e início do século XX na cidade de Pelotas, Rio Grande do Sul. Desde o surgimento deste tipo de residência na segunda metade do século XIX até, pelo menos, os anos de 1920 – década final a qual esta pesquisa abrange – houve um grande esforço por parte do governo e das elites locais, permeado de preceitos originários das políticas higienistas, para que os mesmos fossem afastados para as periferias da cidade. A partir dos movimentos de expansão urbana, o centro da cidade, seus terrenos e edificações valorizaram em termos econômicos. Por tal motivo, os cortiços deveriam sair desta zona central tanto por questões estéticas quando para que houvesse uma maior valorização deste centro.Abstract: The following paper talks about the formation, urban expansion and the emergence of 19th and early 20th century slums at Pelotas city, Rio Grande do Sul state. Since the rise of this kind of residential building, during the second half of the 19th century up to, at least, the 1920s – the last decade covered by this research – government and local elites had been putting a great effort in order to move away from these residences towards the outskirts of the city. All of this ideas were paved around hygienist ideals. Lots and edifications in downtown Pelotas had an increase in economic value because of the expansion of that area. That being said, it was important to force a migration of these slums, away from central areas, based upon aesthetic reasons and in order to increase even more the value of the area.
