Development of a Diagnostic Tool to Measure the ICT Literacy Competency of College Freshmen: A Focus on the Case of M University
Authors:   Korean Association for Literacy, Ku Jin-Hui
Published: January 2024

This study aims to develop a diagnostic tool to measure the information and communications technology (ICT) literacy capabilities of college freshmen. In the increasing dependence of ICT on teaching and learning, the diagnostic tool will help in operating software education for all freshmen, especially non-majors. To develop the diagnostic tool, ICT literacy competency diagnosis area and subattributes were defined through domestic and international literature study and empirical research. Moreover, diagnostic questions for the sub-attributes were developed. To validate the diagnostic tool, content validity was analyzed twice by experts, and a preliminary survey was conducted on freshmen from different departments. Through a preliminary survey, a diagnostic tool of ICT literacy competency was developed, comprising 30 questions. SPSS 24.0, R, and Excel 2016 programs were used to analyze the data. Additionally, differences in performances by department and area were analyzed for ICT literacy competency. Item analysis, percent correct, difficulty of percent correct, and item differentiation were also analyzed. Results show that average scores for information creation and information management capabilities for all freshmen by department, excluding natural science and engineering departments, were lower than those for other capabilities. This shows that they are not proficient in employing commonly used ICT tools and adept in general computer management tasks such as file compression and copying. Furthermore, art department students showed statistically significantly lower scores in all competencies than students of other departments. Therefore, different curriculum composition, programming language selection, and teaching and learning strategies are necessary when providing software education to all students. The ICT literacy competency diagnosis tool is essential to evaluate students’ performance levels and determine their actual proficiency in handling ICT.
Design of writing education method to strengthen coherence: Focusing on Chinese learners in KFL environment
Authors:   Korean Association for Literacy, Wen Xiaobing , Min Jungho
Published: January 2024

This study analyzed how to design a writing education method for strengthening coherence targeting Chinese learners in the KFL environment. To this end, this study analyzed the current state of writing education in Chinese universities and theoretically reviewed the concept of coherence and the principles of writing method design. Focusing on the semantic disconnection problem in the writing lesson, we analyzed how coherence can recover the semantic disconnection problem. Therefore, by utilizing the coherence such as ‘Dicto-Comp’, which can integrate listening and writing, ‘purpose, audience, and context of situation’, ‘macrostructure’, ‘cohesion’, and ‘information distribution’, ‘propositional development’ is explored. An educational method that can be implemented concretely in terms of improvement was suggested. This study will be meaningful in that it analyzes the coherence of writing at the level of content and helps Chinese learners understand how to compose the content coherently when writing.

Published: January 2024

This study examined the influence of school resources on the effective implementation of e-learning in secondary schools in Kasese Municipality, Uganda. Specifically, the study investigated the impact of tangible resources, intangible resources, and school capabilities on e-learning in these schools. Using quantitative research approach, the study employed a correlational research design and collected data from 170 teachers using a self-administered questionnaire. The data were then analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM). The results of the SEM analysis revealed that school resources, namely tangible resources (? = 0.266, t = 3.612, p = 0.000<0.05), intangible resources (? = 0.234, t = 2.351, p = 0.019<0.05) and capabilities (? = 0.456, t = 5.129, p = 0.000<0.05), had a significant positive influence on e-learning. Based on these findings, the study concluded that tangible and intangible resources and school capabilities are necessary for the effective implementation of e-learning in secondary schools. The study recommends that the Ministry of Education, school directors, and head teachers ensure that schools have sufficient tangible resources for e-learning. Additionally, directors and head teachers should also ensure that schools possess adequate intangible resources and capabilities to support the effective implementation of e-learning. The practical significance of this study lies in its demonstration of how existing resources in schools can be utilised to implement e-learning in secondary schools effectively.
Talking to Tyrants in Classical Greek Thought
Authors: Unruh Daniel
Published: January 2024

Talking to Tyrants breaks new ground in the study of Classical Greek history and political thought, exploring the previously unexamined question of how citizens of Greek city-states approached interaction with kings, tyrants, and other absolute rulers. Throughout history, states that value collective government and civic liberties have struggled with how to deal with communities that reject these values. Modern, western democracies continually debate how to reconcile their beliefs in human rights and public institutions with the apparent need to maintain contacts with a range of dictatorships and authoritarian regimes. Greek poleis of the fifth and fourth centuries BCE faced similar challenges. Through a close reading of several Greek authors, in particular Herodotus, Xenophon, Isocrates and Plato, Talking to Tyrants details the different strategies that these authors depict, adopt, or recommend for enabling communication between the very different worlds of the Greek city state and the monarch’s court. The study is further informed by contemporary Intercultural Communications Theory, which provides a powerful framework for examining the ways in which individuals from different cultures and political systems interact. Talking to Tyrants examines how Greek city-states of the fourth and fifth centuries BC with democratic systems of government such as Athens communicatedwith kings, tyrants and oligarchs, whose political structure and ideology wholly differed from their own.
SEISMIC PERFORMANCE SENSITIVITY ANALYSIS TO RANDOM VARIABLES FOR CABLE TRAY SYSTEM
Authors: Fu Zhaoyang , Wu Siyuan
Published: January 2024

Random variables introduced in modelling of seismic engineering are often the result of cognitive limitations and the unpredictability of structures, leading to uncertainties in the field. A practical method for dealing with them is to develop sensitivity analysis in the framework of data and probability statistics. Of existing non-structural components, cable tray systems are characterized by a number of uncertainties which may influence their bearing capacity drastically. In this research, the main characteristics of material, geometry, member layout along with the connection stiffness in cable tray are considered as random variables using global sensitivity analysis, with their results relative importance of these potential uncertainties on the seismic performance of cable tray. The sensitivity analysis method developed especially for cable tray under seismic excitation is constructed based on modal analysis and equivalent inertia force method combined with the Latin hypercube sampling method. The final results demonstrate the need to consider the effects of random variables in modeling assumption in seismic performance analyses of cable tray and can be further used in optimization design.

Published: January 2024

We report the dynamical classifications of 3357 observed outer solar system objects listed as transneptunian objects (TNOs) or Centaurs by the Minor Planet Center. We use the Gladman et al. classification scheme to identify 28 Jupiter-coupled objects (all secure), 168 Centaurs (all secure), 234 scattering TNOs (70 secure/164 insecure), 204 detached TNOs (118 secure/86 insecure), 1650 classical TNOs (1494 secure/156 insecure), and 1073 resonant TNOs (907 secure, 166 insecure). Among the resonant TNOs, the most observationally populated resonance is the close-in 3:2 MMR with 452 objects, followed by the 2:1 with 105 objects, the 7:4 with 103 objects, the 5:3 with 68 objects, and the 5:2 with 56 objects. We discuss a few notable objects here, but all classifications and plots of the 10 Myr integrations are available in a linked GitHub repository.
A polygonal topology optimization method based on the alternating active-phase algorithm
Authors: Cui Mingtao , Cui Wennan , Li Wang , Wang Xiaobo
Published: January 2024

We propose a polygonal topology optimization method combined with the alternating active-phase algorithm to address the multi-material problems. During the process of topology optimization, the polygonal elements generated by signed distance functions are utilized to discretize the structural design domain. The volume fraction of each material is considered as a design variable and mapped to its corresponding element variable through a filtering matrix. This method is used to solve a multi-material structural topology optimization problem of minimizing compliance, in which a descriptive model is established by using the alternating active-phase algorithm and the solid isotropic microstructure with penalty theory. This method can accomplish the topology optimization of multi-material structures with complex curve boundaries, eliminate the phenomena of checkerboard patterns and a one-node connection, and avoid sensitivity filtering. In addition, this method possesses fine numerical stability and high calculation accuracy compared to the topology optimization methods that use quadrilateral elements or triangle elements. The effectiveness and feasibility of this method are demonstrated through several commonly used and representative numerical examples.

A new image encryption based on hybrid heterogeneous time-delay chaotic systems
Authors: Zhou Yuzhen , Zhu Erxi
Published: January 2024

Chaos theory has been widely utilized in password design, resulting in an encryption algorithm that exhibits strong security and high efficiency. However, rapid advancements in cryptanalysis technology have rendered single system generated sequences susceptible to tracking and simulation, compromising encryption algorithm security. To address this issue, we propose an image encryption algorithm based on hybrid heterogeneous time-delay chaotic systems. Our algorithm utilizes a collection of sequences generated by multiple heterogeneous time-delay chaotic systems, rather than sequences from a single chaotic system. Specifically, three sequences are randomly assigned to image pixel scrambling and diffusion operations. Furthermore, the time-delay chaotic system comprises multiple hyperchaotic systems with positive Lyapunov exponents, exhibiting a more complex dynamic behavior than non-delay chaotic systems. Our encryption algorithm is developed by a plurality of time-delay chaotic systems, thereby increasing the key space, enhancing security, and making the encrypted image more difficult to crack. Simulation experiment results verify that our algorithm exhibits superior encryption efficiency and security compared to other encryption algorithms.
Ways of Being Smart in Engineering: Beliefs, Values, and Introductory Engineering Experiences
Authors: Kramer Amy , Kajfez Rachel Louis , Dringenberg Emily
Published: January 2024

Common discourse conveys that to be an engineer, one must be “smart.” Our individual and collective beliefs about what constitutes smart behavior are shaped by our participation in the complex cultural practice of smartness. From the literature, we know that the criteria for being considered “smart” in our educational systems are biased. The emphasis on selecting and retaining only those who are deemed “smart enough” to be engineers perpetuates inequity in undergraduate engineering education. Less is known about what undergraduate students explicitly believe are the different ways of being smart in engineering or how those different ways of being a smart engineer are valued in introductory engineering classrooms. In this study, we explored the common beliefs of undergraduate engineering students regarding what it means to be smart in engineering. We also explored how the students personally valued those ways of being smart versus what they perceived as being valued in introductory engineering classrooms. Through our multi-phase, multi-method approach, we initially qualitatively characterized their beliefs into 11 different ways to be smart in engineering, based on a sample of 36 engineering students enrolled in first-year engineering courses. We then employed quantitative methods to uncover significant differences, with a 95% confidence interval, in six of the 11 ways of being smart between the values personally held by engineering students and what they perceived to be valued in their classrooms. Additionally, we qualitatively found that 1) students described grades as central to their classroom experience, 2) students described the classroom as a context where effortless achievement is associated with being smart, and 3) students described a lack of reward in the classroom for showing initiative and for considerations of social impact or helping others. As engineering educators strive to be more inclusive, it is essential to have a clear understanding and reflect on how students value different ways of being smart in engineering as well as consider how these values are embedded into teaching praxis.
Benefits of Metaverse Application in Education: A Systematic Review
Authors: Flores-Castañeda Rosalynn Ornella , Olaya-Cotera Sandro , Iparraguirre-Villanueva Orlando
Published: January 2024

The COVID-19 pandemic has brought about significant changes in people’s lifestyles, with the educational sector being one of the most reliant on technology to facilitate the teaching and learning process. In this literature review, a search for articles related to the metaverse in education, published in 2022 and 2023, has been conducted across six databases: Scopus, EBSCO Host, ScienceDirect, Taylor & Francis Online, IEEE Xplore, and Springer. The PRISMA methodology was used to analyze and systematize the manuscripts found. The aim of this research was to examine how integrating the metaverse into education can enhance educational accessibility and equity by enabling students to utilize virtual learning resources and opportunities. In addition, they can engage in interactions with others to learn and create interactive content during the teaching and learning process. This requires a commitment from the student because a connection between the student and the machine will be established through the use of emerging technologies. These technologies offer unique opportunities to enhance teaching quality, broaden access to education, and prepare individuals for an increasingly digital and evolving world. The analysis identified 14 emerging technologies: artificial intelligence, cloud computing, big data, Internet of Things, blockchain, augmented reality, extended reality, virtual reality, 5G, EON-XR, digital twins, 3D virtual reality, and immersive virtual reality. These technologies offer immersion (simulation of a real world in a virtual world), interactivity (interaction with different people), improvement of the educational environment (innovative presentation of content), and motivation for learning (capturing attention). When it comes to the different types of learning, there are six categories: experiential (based on experience), collaborative (involving a guide to lead the process), cooperative (involving teamwork), significant (building on existing knowledge), explicit (self-directed learning), and emotional (involving the regulation of emotions).
Controversies over the commercial reappropriation of “Creole” ethnobotanical knowledge traditionalized
Authors: Sion Jim
Published: January 2024

On Reunion Island, controversy has arisen over the use of knowledge regarding medicinal plants to generate economic profit. This article begins by reviewing how use of this knowledge has evolved. It shows how the knowledge came to be preserved as a cultural heritage and celebrated as a token of a certain Creole identity. It then describes how a means of economic development based on this knowledge was introduced in the early 2000s. It grew into an agricultural value chain of aromatic and medicinal plants that mainly produces standardized herbal tea bags. The article describes the complaints that arose when those who had until then shown no interest for this knowledge and had even condemned it, took a certain ownership of it by commercializing it. The fact that traditional practitioners use an accusatory tone to qualify the situation as a usurpation questions the legitimacy of those who seem to benefit the most from these developments. Whether downstream of the value chain in pharmacies or upstream in industrial companies, it has become apparent that people in privileged socio-racial positions are at the top of the economic chain commercializing this knowledge. This confirms that the development trajectory chosen reinforces structural inequalities, and it opens the debate on how to find fair economic prospects.
Res publica. Étude et réception d’une constellation

Comment, en se basant sur l’ouvrage de Claudia Moatti Res publica. Histoire romaine de la chose publique, dessiner les contours de ce que serait une science historique de l’antiquité qui isole, pour s’en prémunir, les représentations politiques qui nous lient à Rome ? On cherche ici à étudier les concepts politiques antiques en plaçant au premier plan les questions de la langue et l’anthropologie des pratiques qu’on essaie de deviner en toile de fond. Ce dossier cherche donc à prolonger l’ouvrage de Claudia Moatti en reprenant l’étude de la Res publica afin de suivre aussi la réception qu’en a fait la postérité.

La prison de Guingamp, de l’ombre à la lumière
Authors: Laot Emmanuel
Published: January 2024

Née d'influences européenne et américaine, au cœur de la réforme carcérale française qui imposa le régime cellulaire en France, la prison de Guingamp est un témoignage architectural unique de l’histoire pénitentiaire française et européenne. Maison d’arrêt et de correction construite par le département des Côtes-du-Nord, elle ouvre en 1841 grâce à Charles Lucas, inspecteur général des prisons, Louis Lorin, architecte départemental et Alexis de Tocqueville, le grand historien, penseur et publiciste français. On leur doit cette mise en forme architecturale humaniste de l’idée qu’une prison n’est pas simplement un lieu d’enfermement. Fermée une première fois en 1934, elle accueille des réfugiés espagnols en 1937 et en 1939, puis rouvre en 1941 pour être désaffectée en 1952. Elle a enfermé 31 661 personnes. Vendue par le Département à l’État, elle sert de lieu d’archivage fiscal, de stockage voir encore de logements. Sans aucun entretien, elle se dégrade fortement, victime de tempêtes et d’un incendie. Achetée en 1992 par la commune de Guingamp, puis inscrite à l’inventaire supplémentaire des Monuments historiques, la démarche aboutit au classement de l’ancienne prison et de son enceinte en 1997. Après plusieurs étapes de travaux de sauvegarde, débutés en 2008, puis de réhabilitation et de réaffectation à partir de 2013 en vue d’un très ambitieux projet artistique et culturel, accessible au public, elle accueille le Centre d’Art photographique GwinZegal en 2019 et l’institut national supérieur de l’éducation artistique et culturelle en 2021.
La prison Winter. Revitaliser le (sombre) patrimoine sherbrookois

Published: January 2024

Ouverte dans la province de Québec en 1869, la prison commune de Sherbrooke (prison Winter) acquiert rapidement une réputation dure, sévère et, surtout, insalubre : malgré différentes phases de rénovations à travers l’histoire du bâtiment, les conditions de vie à la prison s’améliorent très peu et mènent à son ultime fermeture, en 1990. Depuis, la prison Winter est laissée à l’abandon. Le Musée d’histoire de Sherbrooke souhaite en faire l’acquisition afin de la transformer en centre d’interprétation et y organiser tant des expositions que des visites guidées et même des jeux d’évasion. En plus des enjeux financiers liés au projet, la revitalisation de la prison Winter soulève des questions de fond. Pourquoi, en effet, faudrait-il sauver ce bâtiment ? L’article expose les modalités envisagées de la reconversion de la prison Winter en musée et les stratégies de transmission qui permettront d’éviter les écueils liés au « dark tourism ».
Écrire l’histoire politique aujourd’hui. Introduction
Authors: Chatriot Alain
Published: January 2024

Il n’est pas simple de faire la présentation d’un dossier de revue atypique qui se veut un travail collectif de la revue Histoire@Politique sur l’écriture de l’histoire politique aujourd’hui. Ni manifeste déclamatoire, ni panorama exhaustif, cette introduction se veut une réflexion sur des manières d’écrire l’histoire politique contemporaine. En rappelant quelques précédents bilans historiographiques, on voit des évolutions assez nettes dans le choix d’objets, la mobilisation d’archives et parfois des débats de méthodes. Notre revue a tenté ces dernières années de se faire écho de cet allongement du questionnaire des historiens. Plus qu’une proclamation théorique, ce texte et ce numéro veulent montrer par l’exemple la vigueur et la vivacité de l’histoire politique.
En quête de l’Algérie française : pour une histoire sociale du politique, de la colonie à la France contemporaine
Authors: Thénault Sylvie
Published: January 2024

Cet article propose une réflexion sur l’Algérie française. Au-delà d’une cause ancrée à l’extrême droite, celle-ci était aussi une réalité sociale. L’Algérie était en effet une colonie de peuplement, dotée d’une forte minorité française (près d’un million de personnes). L’historiographie l’a appréhendée en minorité coloniale sur la défensive, vivier de recrutement pour l’OAS mais aussi milieu propice à l’action clandestine et violente de cette organisation. Ainsi se dégage une perspective d’histoire sociale du politique, renouvelant potentiellement l’histoire de l’OAS ; une histoire à suivre après 1962 lorsque, dans leur immense majorité, les Français d’Algérie gagnent la France métropolitaine.
L’histoire de l’intégration européenne au-delà du tournant critique
Authors: Warlouzet Laurent
Published: January 2024

L’histoire de l’intégration européenne est singulière car animée par un puissant courant critique. Il repose sur la stigmatisation d’une histoire censée être complaisante envers une dynamique technocratique et issue en partie de Vichy. Or l’étude de l’historiographie francophone de l’histoire de l’intégration européenne permet au contraire de réfuter ces critiques en les remettant en perspective dans une histoire plus globale, à l’image d’un champ qui s’est considérablement renouvelé en s’ouvrant. L’Union européenne n’est plus étudiée comme un isolat, mais comme une partie de dynamiques historiques qu’elle éclaire d’une lumière révélatrice.

Authors: Agarwal Gaurav , Sharma Nitin , Khan Javed , Gupta Bhavna
Published: January 2024

Introduction - Dexmedetomidine has been demonstrated to be safe and effective in various neuraxial and regional anesthetic procedures in humans, with fewer adverse effects in several studies.Methodology - This study aimed to study and compare the efficacy of Dexmedetomidine 1μg/kg plus 0.5% Ropivacaine versus 0.5% Ropivacaine alone in brachial plexus block by supraclavicular approach. After obtaining institutional ethics committee approval this prospective, randomized, comparative study was conducted on 60 patients, 18-60 years, either sex scheduled for elective upper limb surgery under supraclavicular brachial plexus block. The primary objective was to study the effects of 0.5% Ropivacaine with Dexmedetomidine 1μg/kg in brachial plexus block in the form of onset and duration of sensory and motor blockade. Secondary objectives included grading the quality of motor block, Sedation Score, Duration of analgesia, Hemodynamic changes, and Side effects, if any.Observations - Group D showed a faster onset and a longer duration of sensory and motor blockage. Rescue analgesia was given with Injection Diclofenac Sodium 75 mg intravenous when patient Numeric Rating Score> 4. The mean sedation score was comparable at baseline, 5th and 10th minutes (P>0.05), significantly higher in Group D from 15th to 480th minutes (P<0.05), and subsequently comparable from 600th to 1440th minutes (P>0.05).Conclusion - When given as an adjuvant to Ropivacaine 0.5% in supraclavicular brachial plexus block, Dexmedetomidine significantly reduces the onset time and increases the duration of sensory and motor block. It also provides excellent sedation during surgery, improves the quality of block, extends the duration of analgesia, and does not cause significant respiratory depression

Discovery of graphene has enhanced attention on industrial scale production of graphene using natural graphite which involves oxidation followed by reduction processes. Aiming for the first time, mass scale production of graphite oxide from Sri Lankan vein graphite of natural purity 99.5% carbon, following an improved Hummer’s method was experimented at optimized conditions minimizing chemical, energy and time wastage. The present study further aimed at determination of pH and manganese ions on successive purification processes of graphite oxide. The X-ray diffraction spectroscopy (XRD), Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) characterizations were followed for verification of products. The wastewater produced from graphite oxide preparation process was systematically tested for Mn2+ ion using Atomic Absorption Spectroscopy (AAS). XRD peaks verified the formation of graphite oxide successfully through a complete oxidation of graphite. FTIR spectrum exhibited characteristic peaks related to typical graphite oxide while SEM shows the typical morphological features. XPS analysis verified complete removal of Mn from graphite oxide after purification. AAS analysis reveals entire removal of Mn after several washing cycles using only water. The investigation concludes that even mass scale production of quality graphite oxide is possible from Sri Lankan pure vein graphite which can subsequently be used to produce precious graphene and derivatives for various high-end applications.
Talus osteomyelitis - tubercular or not?
Authors: Girdhar Nidhi , Deshpande Satyajit , Agrawal Pallav
Published: January 2024

Tuberculosis is a communicable infective disease caused by Mycobacterium tuberculosis (MTB). The most commonly involved organ is the lung (Pulmonary tuberculosis), however, MTB can affect any organ other than lungs; in this cases, it is known as Extrapulmonary Tuberculosis (EPTB), which can lead to significant morbidity and mortality. Patients with EPTB can rarely develop ankle or foot arthritis, which usually is either misdiagnosed or diagnosed very late, leading to complications. Early diagnosis and timely treatment are very important to prevent permanent functional disability, thus a high suspicion, even in the absence of specific symptoms, is a must. We report a rare case of osteoarthritis of talus which was tubercular, and in which the patient responded well to treatment.

Published: January 2024

Schizophrenia is a mental health problem that is quite widespread in Indonesia. Relapse among patients with Schizophrenia is related to parenting style and family support. This study aimed to present a literature review that address parenting style, family support, and relapse among schizophrenia patients. Three databases were used in this study, ProQuest, Google Scholar, and PubMed. The keywords were used according to the Medical Subject heading (Mesh): Parenting and families support or emotional support and family functioning and relapse and Schizophrenia. We limited the articles from 2020-2022 and in English. We obtained 434 articles which divided into Google Scholar 214 articles, ProQuest 134 articles, and PubMed 86 articles. In the end, we obtained six articles. The methodology of articles was evaluated using JBI Critical checklist. Scores less than 50% were excluded from the study to ensure the quality of the articles. The review results showed that parenting style and family support are risk factors contributing to relapse among schizophrenia patients. However, there was one article showed that there was no correlation between family cohesion and relapse among schizophrenia patients. Parenting style and family support has a function in preventing relapse among schizophrenia patients. So, parenting style and family support management are needed to address intervention for preventing relapse among schizophrenia patients.

Published: January 2024

Labor pain is a manifestation of the contraction (shortening) of the uterine muscles. Non-pharmacological treatment in pain management, namely deep breathing relaxation and counterpressure massage is an alternative method and a new trend that can be developed. This study investigated the effectiveness of deep breathing relaxation and Counterpressure massage in alleviating labor pain during active phase I. Employing a quasi-experimental design with a two-group pre-test post-test approach, 30 postpartum mothers from June to July 2021 were consecutively sampled. Deep breathing relaxation (5 times for 3-5 minutes) and counterpressure massage (3 times for 30-90 seconds) served as the independent variables, while pain intensity during the first active phase was the dependent variable. Utilizing the Wilcoxon and Mann Whitney tests at a 5% significance level, significant reductions in pain intensity were observed after both interventions (p-values: 0.002 for deep breathing, 0.046 for counterpressure massage). These non-pharmacological methods, enhancing endorphin release, contribute to relaxation and pain intensity reduction during labor. The findings underscore the potential of integrating deep breathing relaxation and counterpressure massage as effective approaches in non-pharmacological labor pain management.

Published: January 2024

INTRODUCTION: The conversion of forests into human lands causes the intrusion of wild animals into the residential area. There is a necessity to prevent the intrusion of such wild animals which causes damage to properties and harm or kill humans. Human population growth leads to an increase in the exploitation of forest areas and related resources for residential and other settlement purposes. There is a need for a system to detect the entry of such animals into habitats. OBJECTIVES: This paper proposes that conversion of forests into human lands causes the intrusion of wild animals into the residential area. METHODS: Deep learning technology combined with Internet of Things (IoT) devices can be deployed in the process of restricting the entry of wild animals into residential areas. The proposed system uses deep learning techniques with the use of various algorithms like DenseNet 201, ResNet50 and You Only Look Once (YOLO). These deep-learning algorithms predict wild animals through image classification. This is done using IoT devices placed in such areas. The role of IoT devices is to transmit the computer vision images to the deep learning module, receive the output, and alarm the residents of the area. RESULTS: The main results are implementation prediction of animals for image processing Datasets used for the prediction and classification indulge the use of cloud modules. It stores the dataset for the prediction process and transfers it whenever needed. As the proposed system is a hybrid model that uses more than one algorithm, the accuracy obtained from the prediction for DenseNet 201, ResNet50 and You Only Look Once (YOLO) algorithm is 82%,92%, and 98%. CONCLUSION: The prediction of those animals is done by a deep learning model which comprises three algorithms are DenseNet 201, ResNet50 and YOLOv3. Comparing the accuracy of an algorithm with higher accuracy is considered efficient and accurate.

В терминах емкостей $\gamma_{\mathcal L}$ описываются устранимые особенности $\mathrm L^{\infty}$-ограниченных решений уравнений $\mathcal Lf=0$, $\gamma_{\Delta}$ - это классические гармонические емкости теории потенциала. Доказывается соизмеримость $\gamma_{\mathcal L}$ и $\gamma_{\Delta}$ при всех $\mathcal L$ и соответствующих $N$. В доказательстве используются некоторые идеи Х. Толсы. Даются различные следствия указанной соизмеримости, в частности, критерии равномерной приближаемости функций решениями уравнений $\mathcal Lf=0$ формулируются в терминах гармонических емкостей.

O objetivo desta pesquisa foi verificar o papel moderador da estrutura de custos na relação entre comportamento assimétrico dos custos e rentabilidade das empresas. Foram usadas regressões com dados em painel e duas medidas para a estrutura de custos para analisar a robustez dos resultados. Os resultados indicaram efeito moderador positivo da estrutura de custos na relação entre assimetria de custos e rentabilidade contemporânea, para as empresas do setor de bens industriais, bem como para assimetria de custos e rentabilidade futura do setor de bens industriais e de consumo cíclico. Estes resultados adicionam conhecimento aos achados anteriores ao evidenciar que empresas que apresentaram comportamento de alta assimetria dos custos tiveram uma rentabilidade média superior na presença de alta proporção de custos fixos. Isso indica que a existência de uma maior proporção de custos fixos na estrutura de custos inverte o efeito negativo da assimetria de custos sobre a rentabilidade, devido ao efeito moderador. Foi observado também que o maior nível de rentabilidade foi verificado em um cenário de menor assimetria de custos e menor proporção de custos fixos. As evidências empíricas do trabalho indicam que a minimização do comportamento assimétrico dos custos é relevante especialmente para empresas com baixa proporção de custos fixos, já que há, nelas, uma relação negativa entre comportamento assimétrico dos custos e rentabilidade. Esses resultados são importantes para que gestores possam analisar e comparar a posição de sua empresa em relação aos concorrentes quanto ao nível de eficiência no ajuste dos custos às variações na demanda.

Esta pesquisa tem o objetivo de identificar a influência do formulation effect nas preferências dos usuários por agregar ou desagregar informações contábeis. Para isso, realizou-se uma survey com 524 estudantes de Administração. Apresentou-se 3 tipos de formulation effect: cenários puros (sem descrição do contexto), cenários com demonstrativos contábeis (especificamente contábil) e cenários descritivos (cenários financeiros com contextualização descritiva). Para análise, utilizou-se de estatística descritiva, qui-quadrado e regressão logística. Como resultados, encontrou-se que as decisões, conforme estipulado pela Teoria da Contabilidade Mental se mostram mais presentes em cenários puros, por não haver contextualização a utilidade de valor percebido influencia nas decisões. Diferentemente de situações de decisões organizacionais (cenários com demonstrativos e descritivos) em que a busca por suporte técnico passa a ter mais importância do que as preferências pessoais. Deste modo, contribui-se com os conhecimentos acerca de informações contábeis, bem como para a Teoria da Contabilidade Mental, visto que se apresenta o formulation effect como fator de influência no comportamento e nas preferências por agregação ou desagregação. Assim, demonstrou-se que as decisões puras são mais impactadas pelas características do decisor ao passo que nas decisões com caráter contábil/gerencial as preferências por suporte técnico assumiram protagonismo em detrimento às características pessoais. Estes achados contribuem tanto no campo das discussões teóricas sobre a importancia da forma de apresentar as informações como também auxilia os preparadores de informações dando-lhes subsídios sobre as preferências dos usuários, visando um melhor suporte informacional e, consequentemente, resultando em decisões e desempenho melhores das organizações.

In the process of injection molding, the vacuum pump rear housing is prone to warping deformation and volume shrinkage, which affects its sealing performance. The main reason is the improper control of the injection process and the large flat structure of the vacuum pump rear housing, which does not meet its production and assembly requirements (the warpage deformation should be controlled within 1.1 mm and the volume shrinkage within 10%). To address this issue, this study initially utilized orthogonal experiments to obtain training samples and conducted a preliminary analysis using gray relational analysis. Subsequently, a predictive model was established based on a one-dimensional convolutional neural network (1D CNN). Input parameters from the injection molding process, including melt temperature, mold temperature, packing pressure, packing time, injection pressure, injection time, and cooling time, were used while warping deformation and volume shrinkage were considered as outputs. Global optimization was performed using the non-dominated sorting genetic algorithm II (NSGA-II), and the optimal combination of process parameters was evaluated using the criterion importance through intercriteria correlation—technique for order preference by similarity to ideal solution (CRITIC-TOPSIS). Moldflow analysis demonstrated that the obtained indicators outperformed the optimization results from orthogonal experiments, confirming the effectiveness of the injection molding process parameter optimization method based on 1D CNN-NSGA-II. In comparison to the pre-optimization results, product warping deformation decreased by 40.68%, and volume shrinkage reduced by 18.14%, and all of them meet the production requirements.

The present study focuses on the facile green synthesis of magnetic nanoparticles (MNPs) using onion waste of Allium Cepa L. (MNP@OW) for effective removal of noxious mercury from simulated wastewater. Photogenically synthesized MNPs were functionalized with DL-homocysteine (HC@SiO2@MNP@OW) for selective mercury adsorption. Various characterization techniques were employed to confirm their physical properties. Vibrating sample magnetometer (VSM) studies indicated MNP@OW’s superparamagnetic nature with a saturation magnetization (Ms) of 48.35 emu/g, while HC@SiO2@MNP@OW had a reduced Ms of 4.52 emu/g due to a coating of non-magnetic silica and DL-homocysteine. Both adsorbents showed optimal adsorption at 80°C and pH 8. However, it is explicitly mentioned that HC@SiO2@MNP@OW demonstrated efficient mercury removal at a lower dosage and shorter contact time compared to MNP@OW. Fast separation times of 6 and 26 seconds for MNP@OW and HC@SiO2@MNP@OW, respectively, confirm their ease of separation from simulated wastewater. The Freundlich isotherm model fit the data well and kinetic analysis supported a pseudo-second-order model, revealing a chemisorption mechanism. Moreover, HC@SiO2@MNP@OW demonstrated high selectivity, even in the presence of co-existing ions. Green synthesized MNP@OW and HC@SiO2@MNP@OW exhibited promising potential as low-cost sorbents for efficient mercury removal from simulated wastewater, making them feasible for wastewater treatment in low-economic countries.
