Authors: Jiang Xuefeng , Li Min , Cheng Lin
Published: May 2024

Several incidents of electric vehicle combustion across various regions in China have brought the safety concerns associated with new energy vehicles into sharp focus within public discourse. Addressing these concerns, this paper explores maintenance decision-making for new energy vehicles through the application of decision trees and machine learning techniques. Initially, the study analyzes how decision trees and machine learning are employed in crafting maintenance decisions for these vehicles. It involves collecting data through internet searches, followed by statistical analyses and preprocessing to set the groundwork for further inquiry. Furthermore, the research advances by developing and refining decision tree models, which facilitate the integration of fault diagnosis and maintenance decision-making processes for new energy vehicles. This effort culminates in the establishment of a robust decision tree model specifically designed for the maintenance of new energy vehicles, which is subsequently evaluated through a detailed case study. The results are presented: the approximation degree of new energy vehicle fault diagnosis based on the decision tree model is 90.58%, 90.67%, 88.09%, 91.28%, and 90.19% at the significant level of α taking the value of 0.01, 0.05, 0.100, respectively. This study provides theoretical guidance on the application of decision trees for the diagnosis and repair of faults in new energy vehicles so that the development of new energy vehicles in China can be ensured.

Authors: Gruden Lucija , Stritih Uroš
Published: May 2024

This study investigates the air quality and ventilation effectiveness in a repurposed museum space with a hybrid ventilation system in Ljubljana, Slovenia. Focusing on CO2 and particulate matter concentrations, the aim is to determine the correlation between these parameters and the suitability of the ventilation system following a change in space use. Measurements were conducted over a four-month period, analyzing data during different occupancy and ventilation scenarios. The study compares observed values with World Health Organization (WHO) guidelines, specifically targeting PM2.5, PM10, and CO2 concentrations. Findings reveal inadequate ventilation in the repurposed museum space, even with hybrid ventilation. CO2 concentrations correlated with PM2.5 and PM10 levels, suggesting CO2 monitoring as an indirect indicator of overall air quality. Recommendations include improving ventilation efficiency and limiting occupancy to ensure adherence to air quality standards.

Authors: Ngadimin Ngadimin , Hamid Abdul , Sahara Yuni , Musdar Musdar
Published: May 2024

In fact, the physics learning process in senior high schools does not encourage students to think critically, resulting in low learning outcomes. This research aims to test the effectiveness of a scientific-based flipped class model to enhance students' critical thinking abilities. The research method used is a quantitative method with a quasi-experimental design, specifically nonequivalent pre-test post-test control group design. The population of this study consists of all tenth-grade science classes at Kutacane State Senior High School 3, and the sampling technique used is total sampling, where tenth-grade science class I serves as the experimental group, while the tenth-grade science class II serves as the control group. The instruments used are observation sheets, tests, and questionnaires. Data were analyzed using the N-Gain test, the classical completeness test, and student response analysis. The results of the study showed that critical thinking skills, as measured by both the classical completeness test and N-Gain test, improved in both classes, with the experimental class showing a high gain index category, while the control class showed a moderate gain index category. Learning using a scientific-based flipped class model is effective in enhancing students' critical thinking abilities because it can facilitate students in accessing the provided learning materials.

Squamous cell carcinoma of the buccal mucosa has an aggressive nature. If cancers originating from the buccal mucosa invade adjacent anatomical structures, surgical tumor resection becomes more challenging. The present case describes the surgical management of a 65-year-old woman with persistent ulceration of the mucosal membrane due to tobacco chewing habit for the past 30 years and a mouth-opening limitation of 10 mm. Radiological investigations revealed a buccal mucosa tumor that had invaded the retroantral space upward with involvement of the anterior border of the masseter muscle by the lateral part of the tumor. In this report, we present the surgical approach to access the masticator space behind the maxillary sinus.

¿Es precario el trabajo en Colombia?
Authors: Hidalgo Villota Mario Eduardo
Published: May 2024

En este artículo se examina el concepto de precariedad laboral en Colombia, que, si bien guarda relación con la calidad del trabajo y la informalidad laboral como síntomas recurrentes y de sentida preocupación en el mundo del trabajo contemporáneo, presenta ciertos rasgos distintivos que ameritan una medición y un análisis particulares. Esta cuestión es examinada rigurosamente a partir de microdatos anonimizados extractados de la Gran Encuesta Integrada de Hogares (GEIH) en el periodo 2007-2022. Su medición se efectúa mediante un índice compuesto que incorpora las principales dimensiones del trabajo precario en coherencia con las aproximaciones conceptuales de la Organización Internacional del Trabajo (OIT). Los resultados obtenidos señalan que la calidad del trabajo es baja y con pocas posibilidades de mejoría y, que en general, la precariedad se manifiesta en aspectos tales como: seguridad y estabilidad, seguridad y protección social, y diálogo y representación social, principalmente.
Non-subjective artificial intelligence in the system of subject-object relations
Authors: Gribkov Andrei Armovich
Published: May 2024

Expansion of functional capabilities of artificial intelligence systems actualizes the question of the possibility of their autonomous activity aimed at cognition and creation of the world. A significant factor determining the properties of artificial intelligence is its subjectiveness. If the world is deterministic, its subjectiveness is not necessary to ensure the functionality of artificial intelligence. Subjectiveness, however, is necessary for the initialization of cognitive or creative activity. A reasonable question arises regarding the ability of non-subjective artificial intelligence to act as a subject of cognition. Studies show that two main forms of participation of non-subject artificial intelligence in the system of subject-object relations are possible: as part of an integrated subject of cognition, in which a human being-operator plays the leading role, or fully autonomous functioning of artificial intelligence initialized (formalized or non-formalized) by the tasks of satisfying human being's needs. The analysis of the properties of cognition by means of artificial intelligence and other cognitive systems shows that the ability to act as a subject of cognition is formed not at the formation of subjectness, but at a lower level - the level of formation of self-consciousness, available to relatively uncomplicated cognitive systems, both natural and artificial. The conclusion about the direct connection between self-consciousness and the ability to cognize follows from the definition of cognition in the logic of subject-object opposition, corresponding to the epistemological interpretation of subject-object relations. However, an alternative ontological interpretation is also possible, which identifies being and consciousness. Such an idealistic understanding of the world corresponds to the philosophy of irrationalism, in the framework of which a reliable answer to the question of the necessity of subjectiveness for solving intellectual problems cannot be obtained.

Tools of the Trade: Teachers’ Qualifications as a Contributory Factor towards Quality Teaching and Learning of Life Sciences
Authors: Teane Florah
Published: May 2024

This study sheds light on the contribution that teachers’ qualifications make during the teaching and learning of the subject of life sciences. Life sciences teachers in one-sub-district in the Mpumalanga Province lacked the relevant qualifications and expertise to teach the subject, and that influenced learner performance in the subject. Systemic issues, such as the Post Provisioning Model (PPM), small schools’ staffing, and teachers’ relevant qualifications, resulted in many life sciences teachers being seen as underqualified and lacking the expertise to teach the subject. A qualitative research design was used where a sample consisting of 20 life sciences teachers was purposefully selected. Two focus groups and one-on-one interviews with 10 participants were used to source data. The findings of this research are that the life sciences teachers’ lack of relevant qualifications to teach the subject has led to teachers’ low self-efficacy in teaching the subject—something that affected learner performance. The study recommends in-service training and continuous professional development to empower teachers on new developments in the subject, as well as revisiting policy for placement of teachers in schools.

Spinal epidermoid cyst associated with limited dorsal myeloschisis
Authors: Hammoud Marouane , Cisse Dramane , Chakour Khalid , Chaoui Mohamed El Faiz
Published: May 2024

Background:

Epidermoid cysts (ECs) are rare benign tumors arising from epidermal cells, associated with congenital abnormalities or acquired through trauma, surgery, or lumbar punctures. They represent <1% of all intraspinal tumors and may be associated with limited dorsal myeloschisis (LDM).

Case Description:

A 7-year-old neurologically intact male had a dorsal skin mass since birth located posteriorly in the midline of the inferior thoracic spine. The mass was palpable, painless, mobile, vascularized, and could be transilluminated. Thoracic magnetic resonance imaging showed an extensive intradural extramedullary cystic lesion extending from D6 to D8 that did not enhance with contrast, accompanied by a subcutaneous fluid collection at D8–D9 communicating with the subarachnoid space. The patient underwent gross total resection of the lesion, pathologically confirmed as an EC. The postoperative course was uneventful, with no recurrence 1 year postoperatively.

Conclusion:

LDM may be associated with ECs. Early diagnosis and surgical resection of these lesions are essential for favorable outcomes.

Molecular-recognition events are highly relevant in biology and chemistry. In the present study, we investigated such processes in the solid state under mechanochemical conditions using the formation of racemic phases upon reacting enantiopure entities as example. As test systems, a-(trifluoromethyl)lactic acid (TFLA) and the amino acids serine and alanine were used. The effects of ball-milling and resonant acoustic mixing (RAM) on the formation of racemic phases were probed by using solid-state Nuclear Magnetic Resonance (NMR) spectroscopy. In a mixer mill, a highly efficient and fast racemic phase formation occurred for both TFLA and the two amino acids. RAM led to the racemic phase for TFLA also, and this process was facilitated upon employing pre-milled enantiopure entities. In contrast, under comparable conditions RAM did not result in the formation of racemic phases for serine and alanine.

Non-Overlapping Arrangement of Identical Objects: An insight for molecular close packing
Authors: Nápoles Duarte José Manuel , Palomares Báez Juan Pedro , Pacheco Contreras Rafael , Chávez Rojo Marco Antonio
Published: May 2024

In this study, we investigate the arrangement of identical objects to achieve non-overlapping configurations, a fundamental challenge across various scientific and engineering disciplines, particularly in the context of molecular close-packing. We introduce the concept of "Maximal Boundary Distance", defined as the largest distance between extreme points of an object in a given direction. This length ensures that aligned objects touch without overlapping. Our approach is validated through mathematical proofs and illustrated with both, two-dimensional and three-dimensional examples, emphasizing applications in molecular systems. We further explore the practical implications of this for the packing of molecular crystals by identifying optimal lattice constants. The stability of these configurations is further analyzed using the Density Functional Tight Binding method. This work not only advances our understanding of object arrangement but also has significant implications for the strategic positioning of molecules in close-packed structures.

Este artigo traz o Projeto de Pesquisa Voz e Teatro (chamado a seguir de Projeto Voz Feminina), do Departamento de Artes da UFRN, ligado ao Grupo de Pesquisa em Corpo, Dança e Processos de Criação - CIRANDAR, coordenado pelas professoras de voz Ma. Mayra Montenegro (da Licenciatura em Teatro da UFRN) e Dra. Eleonora Montenegro (da Licenciatura em Educação Musical da UFPB). Nascido em 2017, a partir do desejo de compartilhar com outras mulheres princípios e práticas vivenciados durante a criação do espetáculo feminista Violetas, dirigido por Raquel Scotti Hirson (Lume Teatro), construído a partir da metodologia da Mímesis Corpórea e Mímesis da Palavra. Esse projeto pesquisa a voz como expressão do Ser no treinamento para atuação e nos processos de criação cênica. Quando essa voz encontra-se limitada por alguma razão emocional ou psicossomática, sua autoexpressão torna-se restrita e seu ser reduzido (Lowen, 1982). Com a fundamentação de pesquisadores/pesquisadoras de várias áreas, este trabalho apresenta processos vivenciados em uma escrita de si (Rago, 2013), depoimentos das participantes, reflexões, recomeços, até as cenas de memórias que se materializaram em corpoesia (Hirson, 2012) e se fizeram som, grito, palavra, voz. Desta forma, uma nova reflexão: Através da reinvenção das próprias subjetividades, a possibilidade de se poder reassumir o controle das próprias vozes e vidas.

O artigo aborda algumas possíveis contribuições da Educação Musical para o desenvolvimento de práticas em torno da palavra no contexto cênico. Partindo de uma reflexão acerca da potencialidade da palavra, a qual, mais do que expressar a letra de um texto, se constitui ato e revelação, destaca duas vertentes de trabalho sintetizadas nas modalidades palavra-vocábulo - presente em propostas de caráter estruturante, seja do texto ou da cena - e palavra-sonoridade - empregada em processos de construção de sentido e, não raro, integrada aos aspectos da escuta e da corporeidade. O artigo propõe, ainda, relacionar procedimentos da pedagogia musical a exemplos provenientes de propostas teatrais.

MODELS OF THE SYSTEM OF COLLECTIVE SELF-ORGANISATION OF UNMANNED AERIAL VEHICLES USING ARTIFICIAL INTELLIGENCE
Authors: Trystan A. , Zhukov D. , Bеrеzhnyi A.
Published: May 2024

The article examines the current state and trends in the development of unmanned aerial vehicles (hereinafter - UAVs), methods and means of their control, self-organisation, flight routing, as well as the involvement of artificial intelligence technologies in the UAV teams system. The main trends in the use of UAVs in the defence sector are analysed. The key problems in this area are highlighted, as well as the shortcomings of existing methods and systems. The article analyses scientific works of domestic and foreign scholars, studies problematic issues and suggests ways of their solution. The introduction of artificial intelligence into the UAV control system has significant potential and makes the development of these technologies urgent. The development of UAV collective control systems, including those using artificial intelligence, allows for the effective use of technology in various fields, ensuring increased coordination, functionality and overall efficiency. At the same time, despite active research in this area, a number of problems related to the development of methods and algorithms for group work still remain unresolved. The issue of integrating information technologies created on their basis and the specifics of their implementation in collective intelligence systems in order to increase the efficiency of solving complex formalised tasks is not sufficiently studied. A method of self-organisation of the UAV team with decentralised control is proposed, in which a number of functions (route planning, distribution of roles, determination of optimal actions, obtaining and processing information) assigned to the onboard control system of the robotic air complex can be performed by each element of the UAV team system due to their self-organisation. The practicality of this method lies in the fact that the UAV's artificial intelligence will constantly self-learn and improve, and if necessary, can be reprogrammed to meet the required conditions of the task. As a consequence, the results and time required to complete missions will improve significantly, while the number of control operators will decrease. It solves a number of problems and shortcomings related to the organisation of the management system, route planning, distribution of roles, speed and completeness of receiving, processing and transmitting information, which in turn improves the security and performance of the system.

Більшість пристроїв-датчиків в системах інтернету речей базуються на енергоефективних мікроконтролерах, обчислювальні ресурси яких обмежені, як і обсяги наявної пам’яті. Підвищення захищеності використання таких пристроїв за допомогою нейромереж є важливою та актуальною проблемою. В статті описана можливість використання штучних нейронних мереж у малих мікроконтролерах з обмеженими ресурсами. Мета даної роботи полягає у перевірці можливості обчислення нейромереж на базі цілочисельної арифметики задля зменшення часу обчислення нейромережі та виключення операцій по нормалізації даних, а також оцінка доцільності використання таких нейромереж у сфері безпеки інтернету речей у порівнянні з традиційними методами, такими як чорні та білі списки. Отримані наступні результати: при переході на цілочисельну арифметику, у порівнянні з плаваючою точкою, точність обчислень результату знаходиться у межах допустимої похибки навчання нейромережі, тобто не змінилася. Час виконання зменшився на 30-96%, в залежності від архітектури мікроконтролеру. Розмір програми знизився на 22-48% також в залежності від архітектури мікроконтролеру. Висновки. Було доказано можливість та доцільність використання нейромереж, оптимізованих для мікроконтролерів з обмеженими ресурсами. Це підвищить захищеність систем інтернету речей особливо перед загрозами автентифікації пристроїв та виявленню вторгнень. Визначено перспективи подальших досліджень.

The article analyzes known algorithms for tracking moving objects. Based on an analysis of known algorithms for tracking moving objects, it was concluded that the best tracking quality in problems with a large number of observed objects is achieved by solutions built on the basis of probabilistic and hierarchical methods. Each of them has complementary advantages, which creates prospects for creating new algorithmic solutions built on the synergy of these approaches. The main task of promising tracking methods is that they should provide ease of scaling with an increase in the number of moving objects that need to be monitored, localize objects in three-dimensional space, and also be able to work with heterogeneous sensors. This approach has both purely technical advantages and those related to the availability of microelectronics components in modern geopolitical realities.

Children are a golden age in their growth, so that various information that comes in both verbally and visually will be recorded well, therefore children aged 2-13 years need to receive assistance and supervision over all their activities. Since the COVID-19 pandemic hit the world, all learning activities have changed to online learning, as a result of online learning, there has been a change in children's attitudes. This change is due to children accessing social media a lot and receiving less guidance from their parents, resulting in excessive use of social media. For children and teenagers who have parents, monitoring will be possible, but for children and teenagers in orphanages, do they receive monitoring, assistance, and supervision from parents? Therefore, in this community service activity, the researcher wanted to know more about monitoring the use of social media by children in orphanages. Several games were carried out to determine the extent of children's use of social media, and as a result, the games could divert children's tendencies to use social media.

The Limits of Nonprofit Sector Resilience: Evidence from Canadian Nonprofit Sector Surveys During the Pandemic
Authors: Shields John , Joy Meghan , Cheng Siu Mee
Published: May 2024

The pandemic has illustrated the need to examine the vital role of the community nonprofit sector. While the nonprofit sector is known for innovatively responding to societal needs—to be resilient—it is also underresourced and precariously situated. The hollowing out of social welfare under neoliberalism shifted service responsibility onto nonprofit providers, justified through the framing that precarity drives resilience. With the magnification of need during the pandemic, the “response resilience” of the sector was put to the test. This article studies Canadian reports on surveys of the community nonprofit sector during the pandemic to assess the state of the sector and to examine tensions between precarity and resilience. Evidence illustrates a community nonprofit sector in crisis and the limits of neoliberal resilience.
