Authors: Dwiningtyas Putri Meirin , Rahmat Adi , Sanjaya Yayan
Published: April 2024

Cognitive load is related to working memory capacity, which affects the cognitive processing system. This study aimed to control the cognitive load of students by using chunking techniques combined with the writing is thinking technique when learning about the human reproductive system. The research was conducted at a senior high school in Tasikmalaya City during the 2020/2021 academic year. 56 research subjects were divided into two groups - the experimental group and the control group. The research method used was quasi-experimental with a post-test-only control group design. Measurement of students’ cognitive load included intrinsic cognitive load (ICL), extraneous cognitive load (ECL), and germane cognitive load (GCL), which was measured using an instrument in the form of a subjective rating scale questionnaire with a scale of 1 – 8. The results showed that learning about the human reproductive system using the chunking technique combined with the writing and thinking technique obtained the average value of a student’s ability to receive and process information was 38.4 (low ICL). The average value of mental effort was 32.8 (low ECL), and the average value of the cognitive load related to student learning outcomes was 73.7 (high GCL). Based on the results of statistical tests with the Mann Whitney two-mean difference test, there were significant differences in the ICL, ECL, and GCL components between the experimental group and the control group, so the use of chunking techniques combined with writing is a thinking technique that can control the cognitive load. The chunking technique combined with writing is a thinking technique that is able to optimize working memory capacity by managing pieces of information and helping students construct knowledge by rewriting the information obtained using their own language.

Published: April 2024

Creative thinking skills can create creative ways and harmonize knowledge with time. However, the analysis of the difficulties of mathematics education students has not been widely discussed, especially in the use of online learning resources. This study analyzes 15 fourth-semester mathematics education students’ difficulties in using online learning resources to apply creative thinking in solving math problems. Instruments consist of creative thinking skills test and a scale of online learning difficulties. The study results found that all subjects were familiar with online learning resources. However, its utilization was still minimal due to various difficulties, such as unstable signals, high quota costs, confusion about choosing an abundance of information, and uncertainty about the correctness of the information. These difficulties have an impact on the limited knowledge of the subject and the ability to generate ideas. Fluency in creative thinking was low. Subject ideas tend to be limited and routine. Subjects prefer to present an idea and immediately apply it to problem-solving. Flexibility is not visible, and errors in responding to ideas still occur. As a result, when the idea is executed incorrectly, the problem-solving is also wrong.

The Importance of Representing STEM Professional Role Models Through Multimedia Instructions
Authors: Marito Tamba Riris , Ling Chia
Published: April 2024

The first part of this paper discusses that STEM education does not have clearly defined fields, unlike discipline-based educational programs such as science education, which do have clearly defined areas. In order to overcome the complexity and ambiguity of different STEM and STEM education perspectives, it is necessary to understand the status and trajectory of STEM education research. Also, the authors suggest that stereotypes about STEM professionals can be minimized by using several faces associated with learners, as role models in presenting information about the career options available to STEM professionals in order to reduce stereotypes. As learners learn STEM, they can recognize their potential and their sense of self as well as their STEM connections. Additionally, by exposing students to various professions through multimedia learning, the distance between role models and learners may be closed, thus appealing to their interests and encouraging them to pursue careers that they are interested in the future.

Published: April 2024

Purpose: The purpose of this paper is to critically evaluate data collected from various studies on Chronic Disease Management during the COVID-19 pandemic and the emergence of Digital Healthcare as a means of providing innovative approaches to manage chronic diseases. Methodology: A systematic literature review was applied. Studies were found after a search in the Pubmed database with no publication date time limit, given that COVID–19 emerged in 2019. A Prisma diagram was created to record the way and the criteria by which we included and excluded studies for our research. Out of the 567 records identified through various sources 85 were used for a qualitative synthesis. Results: During the first wave of the pandemic, a significant reduction or complete cancellation of scheduled health appointments was observed. Shortages of medication used to manage chronic conditions were also observed at the beginning of the COVID-19 pandemic due to global supply chain disruptions. Governments acted rapidly at the beginning of the pandemic to promote the use of teleconsultations by introducing enabling legislation and revising laws ensuring continuity of care for people with chronic diseases, thus transitioning rapidly to remote care and monitoring. Conclusion: Telemedicine and involving community pharmacists in chronic patient management are key for sustained adherence. Long-term policies are vital to prevent pandemic-driven health disparities. Lessons should be derived for future preparedness, managing subsequent waves, and ensuring testing in primary care.
Considerações históricas aleatórias sobre uma Faculdade de Medicina internacionalizada
Authors: Magalhães Pedro Jorge Caldas
Published: April 2024

No início do século XX houve a primeira tentativa de criar uma Faculdade de Medicina na capital cearense. Em 1913, sob a presidência primeira do médico e historiador Guilherme Studart, o Barão de Studart, foi criada a Associação Médica e Farmacêutica, conhecida depois como Centro Médico Cearense, entidade que congregava 29 médicos, 18 farmacêuticos e 8 cirurgiões-dentistas em sua primeira composição. Na esteira desse movimento, criou-se, em 1914, a Faculdade de Medicina Tropical, Farmácia e Odontologia, tendo como primeiro diretor o então vice-presidente do Centro Médico, Eduardo Salgado. A proposta, entretanto, não prosperou e a recém-criada entidade se desfez. Assim, em 1916, farmacêuticos e cirurgiões‑dentistas fundaram a Faculdade de Farmácia e Odontologia do Ceará. Décadas depois, a escola de Enfermagem foi incorporada, formando assim a Faculdade de Farmácia, Odontologia e Enfermagem (FFOE) no Campus do Porangabuçu da Universidade Federal do Ceará (UFC).
The Artificial Intelligence, Challenges for Accounting Profession. The Case of ChatGPT
Authors:   Bucharest University of Economic Studies, Romania, DUMITRASCU Luminita Mihaela
Published: April 2024

The implementation of Artificial Intelligence (AI) in the accounting field represents a hot topic. ChatGPT, an AI tool, became very popular recently, due to its conversational voice and abilities. The study is motivated less by the evolution of this Large Language Model (LLM), and more by its capabilities. This paper explores the impact of AI on accounting and accountants, in a dynamic world, with a focus on financial reporting. The research discusses about using AI technologies, more exactly ChatGPT 4, as tools available for accountants, and how they are changing the way financial data is processed, analyzed, and reported. The objectives of the author are to examine the potential advantages, benefits, limits, and risks associated with AI implementation in accounting, including increased accuracy and efficiency, as well as concerns around data privacy and security. In this regard, a quantitative method of research was used. It was realized an experiment with testing ChatGPT and its capabilities. Furthermore, the author argued that accountants need to develop new skills and competencies. This includes a deep understanding of AI algorithms and their limitations, as well as the ability to interpret and communicate the results of AI-driven analysis to non-technical stakeholders. By embracing AI technologies and developing new skills and competencies, accounting professionals can contribute to the long-term success of organizations in a dynamic and rapidly changing world. The paper also considers the challenges of detecting and preventing dishonesty and suggests strategies that accountants can implement to ensure integrity to use of these tools. These strategies refer to policies and procedures, providing training and support. The added value of this paper is the fact that provides an understanding of the implications of AI on accounting. The paper concludes that while the use of AI for accounting in a dynamic world presents benefits and opportunities, there are also some challenges to face. Accountants can effectively address these concerns by taking a proactive and ethical approach to the responsible use of these tools. Future research could be represented by creating focus groups and interviews with different stakeholders to observe the impact of ChatGPT in a business environment, by discussing both financial and nonfinancial reporting.

Published: April 2024

The daily variation of organic contaminants, both gaseous and associated with suspended particulate matter (PM), was investigated within the estate of the National Company of Paintings in Lakhdaria, Algeria, spanning the period 2014-2015. The research emphasizes the chemical characterization of suspended PM, analyzing a range of organic compounds, including n-alkanes, polycyclic aromatic hydrocarbons (PAHs), and highly polar organics (HPOC), such as phthalate esters and heterocyclic compounds. Vapors of PAHs and polychlorobiphenyls (PCBs) were also analyzed. Low molecular weight compounds were primarily associated with the gas phase (two-ring PAHs, approximately 95%; three-ring PAHs, around 70%), while high molecular weight congeners were mainly associated with the particle phase (six-ring PAHs, 55%). The concentrations of PCBs (ranging from 0.6 to 42 ng m–3) were higher than those reported in other cities in Algeria and Europe. The source reconciliation of organic contaminants through principal component analysis (PCA) demonstrated that the primary sources were petroleum combustion, industrial manufacturing, tobacco smoking, and vehicular traffic. The significance of tobacco smoke was further confirmed by the analysis of PAH diagnostic ratios. Differences in the rates of diagnostic ratios between gaseous and particulate PAHs were attributed to distinct contributions from sources such as industrial processes. Health risks for workers exposed to PAHs and PCBs in PM < 10 μm (PM10) were quantitatively assessed in terms of benzo[a]pyrene equivalent concentration and incremental lifetime cancer risk (ILCR). The ILCR presents novel findings showcasing heightened risks among workers exposed to specific PAHs within production areas, whereas those related to PCBs suggested a high potential of health risks for laboratory workers.

Authors: Zhang Jin , Zhuang Guodong , Lv Jinling , Zhang Junjia , Hu Feng , Chen Yongsheng
Published: April 2024

Research has shown that the consumption of herbal teas is linked with positive effects on the regulation of postprandial blood glucose level. In this study, a comparative analysis of aqueous and ethanol extractions is performed on four herbal teas (Mallotus, Cyclocarya, Rubus, Vine) to evaluate their phytochemical profiles and functional activities. Investigations of phytochemical contents, antioxidant activities, α-glucosidase inhibitory activities and chemical compositions are carried out through colorimetric analyses and UPLC-Q-Orbitrap HRMS/MS, respectively. Results showed that among the studied herbal teas, Vine exhibited the highest glucose re-gulating abilities under both aqueous and ethanol extractions. Overall, ethanol extracted samples yielded higher phytochemicals content, but the compositions of the phytochemicals varied. Meanwhile, aqueous extracts showed surprisingly strong antioxidant activities and comparable α-glucosidase inhibitory activities with ethanol extracts. Phytochemicals contents presented a positive correlation with antioxidant activities and α-glucosidase inhibitory activities. Nevertheless, antioxidant activities displayed a weak positive correlation with α-glucosidase inhibitory activities. Results from this study provided evidence that aqueous extracts from herbal teas possessed valuable phytochemicals composition for antioxidants and the hyperglycemic populations, and are promising candidates for potential applications as functional ingredients with health promoting effects and as natural additives to boost the nutritional value of herbal food products.

Authors: Mansoori Solmaz , Härkönen Janne , Haapasalo Harri , Annunen Petteri
Published: April 2024

Productivity has been modest in construction due to many reasons, especially project-specific operations and fragmentation. The main aim of this research is to map the challenges towards industrialization in construction through a comparative study of the manufacturing industry. An inductive approach and a qualitative method are followed by applying semi-structured inter-views, and node-based thematic analysis. The key elements of industrialization in mature man-ufacturing companies are benchmarked. The findings indicate a specific order of steps for indus-trialization in construction. Data and information management with achieved systematization have been sources of productivity in manufacturing companies. However, the systematization starts from the offering, construction companies need to define their offering, that is the products, and define their respective data. Only accurate and good quality data on products enables the systematization of order delivery processes, which are the engine for a company’s success or failure. Continuous efficiency improvement is only possible with systematized processes and respective data related to the processes. The originality involves clarifying the industrialization of construction companies via products, respective data, and processes considering industrialized manufacturing companies.

Authors: Manservisi Sandro , Barbi Giacomo , Cervone Antonio , Giangolini Federico , Sirotti Lucia
Published: April 2024

This paper investigates a numerical code coupling technique to tackle multi-physics and multi-scale simulations using state-of-the-art software packages that typically address some specific modeling domain. The coupling considers the in-house FEM code, FEMuS, and the FVM code OpenFOAM, by exploiting the MED library from the SALOME platform. The present approach is tested on a buoyancy-driven fluid flow within a square cavity, where the buoyancy force constitutes the coupling term. In uncoupled scenarios, momentum and temperature equations are solved both in FEM and FVM codes without data exchange. In the coupled setting, only the OpenFOAM velocity and the FEMuS temperature fields are solved separately and shared at each time step (or vice versa). The MED library handles the coupling with the addition of suitable ad-hoc data structures that perform the field transfer between codes. Different Rayleigh numbers are investigated, comparing the outcomes of coupled and uncoupled cases with reference literature results. Additionally, a boundary data transfer application is presented to extend the capabilities of the coupling algorithm to coupled applications with separate domains. In this problem, the two domains share interfaces and boundary values on specific fields as fluxes are exchanged between the two numerical codes.

To understand how the thinning strategies impacts on wood quality and quantity for different purposes is of interest, considering that the management of plantations is carried out with parameters that have yet to be validated for different growth conditions. This work evaluated contrasting thinning regimes applied early at two moments of the crop cycle. With an initial population of 840 trees.ha-1, two thinning with populations ranging from 700 to 400, and from 400 to 100 trees.ha-1 were applied at 1.5 and 7.3 years, respectively. Growth analyses were carried out from the ages of 1.5 to 20.8 years considering: total height, diameter at breast height, individual volume, total and commercial volume per hectare, mean annual increase and current annual increase. At final age, contrasting populations of 100, 250 and 400 trees.ha-1 were sampled to assess wood density, and mechanical properties (bending and compression on small scale clear samples). The values of individual growth and wood properties are related to a Stand Density Index to understand the effect of competition on those values. The results allow us to identify the thinning schemes that record the most significant individual and per-hectare growth (both in thinning and clear felling) and the optimal harvest time under specific growth conditions. We assessed the proportions of commercial logs for sawmill and pulp uses, providing valuable inputs for a subsequent economic analysis of thinning regimes seeking for the most convenient combination of wood products. Wood's physical and mechanical properties assessed were barely affected by contrasting levels of competition between trees, therefore the decision of the silvicultural system to implement will depend on production and economic criteria.

Published: April 2024

The traditional societies evolved locally with the realms of time in their calendars while modern Gregorian based on the solar movement and some others use lunar or the combination with solar. Unveiling some information from the old manuscripts to gain the realm of traditional Batak people since the ancient times in settlements surrounding the tropical Lake Toba, North Sumatera, Indonesia, revival of cosmos is delivered. Uniquely the ancient Batak count days in a month by observing lunar phase and the period of year is by looking the observable Constellation of Orion & Scorpius within the new phase of the moon. Thus there are years with 12 months and some leap years with 13 months, and we propose to categorize the calendar to be lunar-star, relative to other widely analyzed calendars. In the realization of the use of the cosmogram, we cross the period of the leap year to the examination of contemporary data on agriculture event, i.e.: crop failure, as well as some profiles on weather. The revival of the Batak Calendar opens further interesting conjectures based on the rich cultural and astronomical knowledge embedded in tradition with deep connection between celestial observations and timekeeping.

The opportunities and advantages of implementing Artificial Intelligence (AI) and Machine Learning (ML) to optimize the process control of wastewater treatment in the Oil and Gas industry are discussed in this work. Discussion is centered around five major points: 1) Various types of Oil and Gas wastewater (Sour, Oily, Produced) and industry standards/methods for treatment, including specific case studies and challenges when treating certain wastewater. This section aims at the common types of wastewater in the Oil and Gas industry and how they are generally treated. 2) How AI/ML has been implemented in wastewater treatment in various industries; summary of which AI/ML languages were used along with a brief overview of how they work. This article focused on an understanding of the specific case studies and AI explanations to understand the effectiveness of wastewater treatment using AI/ML. 3) AI that is currently implemented in Oil and Gas such as personal protective equipment (PPE), smartwatches radiofrequency identification etc. This showed that AI/ML already plays a successful role in the Oil and Gas industry and has proven to help optimize many processes and components. Many of these AI/ML implementations are now industry standards and have greatly benefitted the industry. This section demonstrates that the implementation and the use of AI/ML have been proven to be a successful endeavor and that expanding the role of AI/ML would be beneficial. 5) Using the established points from the previous sections the paper outlines why AI/ML is ideal for Oil and Gas wastewater treatment; this argument centers around fit-for-purpose treatment, and the possible uses of the treated water. A determination of the best-suited AI languages, possible implementation scenarios, and how this would shift the way Oil and Gas industries treat and approach wastewater is presented to the reader.

Biological neural network (BNN) is the core brain for creature to accomplish its intelligent behaviors through unique network structure and mechanisms. It also inspires controlling human-designed autonomous agents including robots to generate more advanced intelligent behaviors by mimicking the neural control mechanism of creatures at a deeper and more interactive level. Here, we constructed a whole-brain neural network model of Caenorhabditis elegans (C. elegans), which characterizes the electrochemical processes at the level of cellular synapse. The neural network simulation integrates computational programming and visualization of neurons and synapse connections of C. elegans, containing the specific controllable circuits summarization with their dynamic characteristics within the whole network. To illustrate its particular intelligent control capability in terms of robotics, we introduce the first innovative methodology for applying the BNN model to a 12-legged robot’s movement control based on the established numerical simulation platforms. We accomplished and designed two methods and corresponding encoding processes, one involving orientation control and the other involving locomotion generation, to demonstrate the intelligent control performance of BNN. Both simulation and experiment results indicate that the robot exhibits stronger autonomy and more intelligent moving performance under the control of BNN. We then summarized the contributions for digitalizing the C. elegans’ whole-brain neural network in real-time and utilizing it to control robot in a closed loop to validate its advanced intelligence control ability in terms of a scientific robot.

Optical materials with a tunable localized surface plasmon resonance (LSPR) are of a great interest for applications in photonics and optoelectronics. In the present study we explored the potential of generating the LSPR band with an ultra-broad range of over 1000 nm in gold nanoparticles (NPs) precipitated through the thermal treatment in ZnO-Al2O3-SiO2 glass. Using the optical absorption spectroscopy, we demonstrated that the LSPR band's position and shape can be finely controlled by varying the thermal treatment route. Comprehensive methods including Raman spectroscopy, X-ray diffraction and high-resolution transmission electron microscopy were used to study the glass structure, while computational approaches were used for the theoretical description of the absorption spectra. Obtained results allowed us to suggest a scenario responsible for such abnormal LSPR band broadening which includes possible interparticle plasmonic coupling effect taking place during the liquid-liquid phase separation of the heat-treated glass. The formation of gold NPs with an ultra-broad LSPR band in glasses holds promise for sensitizing rare earth ion luminescence for new photonics devices.
