Authors: Abd. Al-Salam Abdulrazak
Published: April 2024

Optical modulator is an important component in optical system. It is a device, which changes the angle between the vision line to the target and coordinate to electrical signal. Through this study we have designed the fractal optical modulator consisting of eighteen sector, by building a computer program (SAM1) using visual basic language. In this paper assume that nine sectors one opaque and the other nine sectors are transmitted for the light. One may consider these nine sectors also as opaque for the other regions of electro-magnetic wave spectrum. For the importance of the modulation transfer function (MTF) in testing and evaluating optical systems, it becomes the dependent measurement to know the optical systems efficiency. It has been studied for optical systems with circular aperture, where that function could evaluated the image efficiency for point object in image plane at different magnitude of transmittance. In this research, the fractal optical modulator has been designed of semiconductor material by using the fractal function. Then evaluating the values of MTF at different values of refractive index and transmittance. The best modulation of Zinc Selenide (ZnSe) material optical modulator was when transmittance (T) 73%. Where the value of MTF is maximum at refractive index η λ=11.0μm (ZnSe) equal to 2.4001. The worst case of modulation was at transmittance (T) 40%. Where the value MTF is minimum at refractive index η λ=0.54μm (ZnSe) equal to 2.6754.

HALAL WITHOUT LABEL: IMPLEMENTATION OF MAQASID AL-SHARIAH IN COMMUNITY-BASED TOURISM IN KERINCI, INDONESIA
Authors: Repelita  , Iskandar Nuzul , Mursal
Published: April 2024

This study aimed to investigate the feasibility of tourism management that upholds halal values and meets maqāṣid al-sharī’ah indicators, without necessarily using a halal label. Specifically, it aimed to understand the community's social, economic, and religious dynamics where a tourist destination grows and is managed. Using an ethnographic approach, the study was conducted in 2022. Data were collected through semi-structured interviews with twenty informants, document analysis and observation. The Spradley model was employed to analyze the data. The findings of this study indicate that the management of Pantai Indah destination in Kerinci Regency emerged in a social context where religion and culture were closely intertwined through acculturation processes. Therefore, tourism in this area is a religious-cultural expression, rather than solely an economic pursuit. This background has allowed tourism to meet the elements of halal without requiring a halal label or special assistance, while still being able to initiate community-based tourism. Moreover, tourism can be measured using maqāṣid al-sharī’ah indicators. However, the study has certain limitations, such as the concentration of data in one community and the lack of comparison with other communities using different typologies, approaches, and characteristics. Nevertheless, this study recommends that the halal tourism program advocated by the government cannot be implemented in a top-down and uniform manner for all regions. This is because, in several areas, the local community has rejected such a program. In fact, halal tourism can be successfully implemented by ensuring its substance without the need for a halal label.
WHAT AND WHO INSPIRED ME TO BECOME A SCIENTIST AND FURTHER A SCIENCE EDUCATOR?
Authors: Tsaparlis Georgios
Published: April 2024

According to Alex H. Johnstone, “most of the concepts we develop in everyday living (such as cars, trees, houses, dogs, and flowers) are based on tangible things; things we can touch, see, smell and taste. … However, concepts such as element, enzyme, atom, gas, resistance, molarity, entropy, and many others cannot be constructed directly by our senses. Some are one or even two steps removed from direct sensory perception” (Johnstone, 2007, p. 8).
The famous Johnstone triangle for the physical sciences (Johnstone, 1982 ─ see Figure 1) has at one of its corners tangible things, constituting the “Macroscopic” or “Macro Level”. The two other levels that facilitate further understanding are the “Symbolic and Mathematical Level”, which involves symbols, mathematical and chemical equations, as well as graphs and calculations, and the “Submicroscopic” or “Submicro Level”, which refers to entities such as atoms and molecules, that are so tiny that we cannot observe them either directly or even with the help of a strong microscope; these entitles are objects of thought and we draw conclusions about them through logical thinking and inferences. The emphasis among the three levels varies between the physical sciences, physics and chemistry.

Published: April 2024

This research is a needs analysis study aimed at developing a curriculum based on an interdisciplinary context-based learning approach within the 10th-grade physics course, focusing on the electricity and magnetism unit. The research was designed according to the case study model and data were collected from expert, teacher, and student sample groups through questionnaires and interview forms. Descriptive statistics were utilized for quantitative data analysis, while content analysis technique was employed for qualitative data. The results indicated that the physics curriculum continued to maintain a disciplinary perspective and a classical understanding of physics, with insufficient connection with daily life and adaptation to contemporary conditions. Similar results were identified in the 10th-grade physics textbooks and in-class instructional practices concerning the unit of electricity and magnetism. In this respect, the research identified the needs for developing a curriculum based on an interdisciplinary context-based learning approach to address these negative results. These needs, while enhancing interdisciplinary context-based understanding, can also contribute to the emergence of various opportunities and different perspectives in physics education. It is recommended to identify needs in other subfields of physics as well and develop curricula designed with an interdisciplinary context-based approach for more effective and efficient physics education.

Authors: Jho Hunkoog , Ha Minsu
Published: April 2024

This study aimed at examining the performance of generative artificial intelligence to extract argumentation elements from text. Thus, the researchers developed a web-based framework to provide automated assessment and feedback relying on a large language model, ChatGPT. The results produced by ChatGPT were compared to human experts across scientific and non-scientific contexts. The findings revealed marked discrepancies in the performance of AI for extracting argument components, with a significant variance between issues of a scientific nature and those that are not. Higher accuracy was noted in identifying claims, data, and qualifiers, as opposed to rebuttals, backing, and warrants. The study illuminated AI's promise for educational applications but also its shortcomings, such as the increased frequency of erroneous element identification when accuracy was low. This highlights the essential need for more in-depth comparative research on models and the further development of AI to enhance its role in supporting argumentation training.

THE PREDICTION OF SCIENCE ACHIEVEMENT WITH SCIENCE IDENTITY AND SCIENCE LEARNING SELF-EFFICACY AMONG CHINA’S UPPER-SECONDARY STUDENTS
Authors: Zhu Jian-Bo , Luo Yu-Zhou
Published: April 2024

Science identity, encompassing perceptions of competence, interest, and recognition in science, alongside learning self-efficacy reflecting confidence to master science skills, are key drivers of outcomes. However, developmental patterns likely vary across contexts. Participants were 512 Chinese students spanning grades 1-3 who completed the Science Identity Scale and Science Learning Self-Efficacy Scale, with physics, chemistry, and biology achievement scores gathered. A Partial Least Squares Structural Equation Model assessed relationships. Results substantiated psychometrics for motivational measures. The model indirectly predicting achievement via first-order discipline-specific paths explained more variance than direct second-order effects. Effects significantly varied across groups stratified by grade and region. Interest and conceptual knowledge drove physics and chemistry success, while higher-order skills enhanced biology achievement overall. However, relationships differed within subgroups, suggesting personalized motivational support needs—self-belief/competence foundations for struggling learners, conceptual development for those with high prior achievement, and intrinsic enrichment for disinterested students. Results detail complex motivational profiles underlying science achievement requiring tailored identity safety and self-efficacy scaffolding alongside conceptual and skill-building for excellence across scientific disciplines. Motivational support systems may spur more equitable and optimal science outcomes among diverse adolescent learners.

Justice Without Retribution? The Case of the System of Communal Security, Justice and Reeducation of Montaña and Costa Chica in Guerrero, Mexico
Authors: Stachurski Alexander
Published: April 2024

This paper discusses a non-state justice system (Sistema Comunitario de Seguridad, Justicia y Reeducación, hereafter: SCSJR) applied by some of the Afromexican and Indigenous communities of the Guerrero state in Mexico as an example of a maximalist restorative justice system. Restorative justice is presented here as an alternative to criminal justice. While it responds to similar moral concerns as retributive justifications do, it offers more adequate mechanisms of dealing with certain crimes and aims to reduce coerciveness of justice when dealing with lawbreaking. Restorative justice is also an approach that should be perceived as more legitimate when handling cases where the state lacks the moral standing to prosecute offenders. The SCSJR is used as an example to demonstrate the possibility of a justice system based on restorative principles to be effective in handling the entirety of lawbreaking in a community. In the case of the SCSJR this approach to justice has been proved to be effective even in the wake of high levels of criminal activity in the region. This paper discusses the SCSJR’s institutions and attitude toward lawbreaking and argues that they demonstrate an example of a justice system based on restorative justice.
Expanding The Scope of The Epistemic Argument to Cover Nonpunitive Incapacitation
Authors: Shaw Elizabeth
Published: April 2024

A growing number of theorists have launched an epistemic challenge against retributive punishment. This challenge involves the core claim that it is wrong (intentionally) to inflict serious harm on someone unless the moral argument for doing so has been established to a high standard of credibility. Proponents of this challenge typically argue that retributivism fails to meet the required epistemic standard, because retributivism relies on a contentious conception of free will, about whose existence we cannot be sufficiently certain. However, the scope of the epistemic challenge should not be limited to doubts about free will or retributivism. In this article, I argue that the epistemic challenge should be expanded beyond the original focus on justifications of punishment. By “expanding the epistemic challenge” I mean demanding that other purported justifications for serious (intentional) harm be held to a high standard of credibility. To provide a focus for the argument, I will concentrate on the “Public Health Quarantine Model” defended by Gregg Caruso, but my arguments have wider implications beyond this model. A growing number of “abolitionist” theorists believe that punishment is wrong in principle. If retributive punishment, or punishment in general, were abandoned, we would need to ask, “how else should we respond to crime?”. My arguments suggest that all such abolitionists will have to face the same epistemic standard as penal theorists if they wish to replace punishment with the intentional imposition of non-punitive severe coercive measures.

Published: April 2024

Introduction: The neonatal stage is important because of its high mortality risk. Neonatal Intensive Care Unit (NICU) is both an important and dangerous place for preterm babies since it can increase the developmental disorders in the baby. Various programs containing several early interventions for preterm babies are implemented and combined into a developmental care model. Objective: This study identified the components, contents, and interventions in the developmental care model for preterm babies that is suitable for Indonesia. Method: This qualitative research was done through Rapid Assessment Procedures (RAP) to produce information quickly to help decision-making, continued by content analysis using Microsoft Excel through several stages, namely case classification, condensing, streamlining meaning, and compiling, hence producing subcontent. Results: The DSC developmental care model looks more detailed, while NIDCM has core components of teamwork and collaboration that are not found in the DSC, thus complementing each other. Conclusion: The NIDCM developmental care model is more applicable than DSC since it can be done in the NICU with limited human resources or staff that are not yet fully trained. Both interventions need to be made shorter, and terms can be created as a combination of both so that they become alternative developmental care.

Authors: Patel Rohit , Singh Prasoon Kumar , Saw Shivam
Published: April 2024

Noise pollution is a significant concern in urban settings, caused by traffic increases, urban expansion, and industrial activity. The transportation sector is a crucial contributor to overall noise pollution, particularly in India, where different vehicles ply the roads, resulting in highly fluctuating noise levels. Consequently, traffic noise modeling is essential for addressing this severe issue. The present study employs the MLR (Multiple Linear Regression) and Artificial Neural Network (ANN) approach to model and predict traffic-induced noise levels. The ANN approach outperforms the MLR technique. The architecture of the ANN model integrates different vehicle categories and average speeds as input, resulting in precise predictions. Evaluation of the model’s performance reveals an average Root Mean Squared Error (RMSE) of 0.204 and a high Coefficient of determination (R2) value of 0.93, emphasizing its accuracy. Similarly, in the case of MLR model the RMSE for the training and testing dataset are 1.55 and 1.69 dBA, respectively with R2 value of 0.84. Subsequently, sensitivity analysis highlights the substantial impact of 2-wheelers, tractors/trailers, and 3-wheelers on noise predictions. This study contributes valuable insights into noise management, urban planning, and sustainable development. It demonstrates the efficiency of the ANN approach in addressing complex noise pollution challenges, offering a path toward quieter and healthier urban environments.
Modelling & Analyzing View Growth Pattern of YouTube Videos inculcating the impact of Subscribers, Word of Mouth and Recommendation Systems
Authors: Babbar Garima , Anand Adarsh , Aggrawal Niyati
Published: April 2024

YouTube, one of the prominent online video-sharing platforms, plays a pivotal role in modern media consumption, making it crucial to understand and predict the view-count dynamics of its videos. The viewership of YouTube videos can be influenced by three distinct sources: subscribers, word-of-mouth, and recommendation systems. This paper presents a comprehensive modelling framework that takes into account the view-count obtained through these three sources, assuming that a single view-count can only be attributed to one of these sources at any given time. We investigate the interplay among these sources in shaping YouTube video view-count dynamics, proposing a novel approach to model and analyse their impact on video popularity. Additionally, the VIKOR multi-criteria decision-making method is employed to validate and rank our proposed models. This study's findings deepen our understanding of the intricate mechanisms within the YouTube ecosystem, offering insights for predicting and managing video viewership.
A Novel Approach for Implementing and Optimizing Proportional-Resonant Controller and L-C-L Filter for Single-Phase Grid-tie Inverter
Authors: Swain Nibedita , Ray Papia , A. Alotaibi Majed , Malik Hasmat , García Márquez Fausto Pedro , Afthanorhan Asyraf
Published: April 2024

This article introduces the design procedure of a 1-phase full-bridge inverter for grid-connected applications. The main idea of modelling a full-bridge inverter is that it plays a vital role in solar energy systems. The dynamic equations are formed with the state-space averaging (SSA) technique. A Small-signal averaged model of a full-bridge inverter is constructed by assuming grid current and capacitor voltage as the two states. The voltage and current controller scheme are based on the frequency domain approach. The voltage controller is designed to maintain fixed voltage, and the current controller is used for controlling grid current. The LCL filter is connected to the inverter to provide better harmonic elimination and filter size minimization. This filter is formed by parallel-series combination of inductance and capacitance to improve the overall system performance. Here, a passive damping method is incorporated to make a balanced steady system. Finally, a proportional integral and proportional resonant (PI-PR) controller is introduced to provide better stability and tracking. The detailed analysis of PR controller is explored and demonstrated by MATLAB simulation.
A Spatial Error Model in Structural Equation for the Human Development Index Modeling
Authors: Anekawati Anik , . Purhadi , Rofik Mohammad , Hidayat Syaifurrahman
Published: April 2024

Spatial regression, particularly the Spatial Error Model (SERM), was utilized in prior studies to analyze Human Development Index (HDI) modeling. However, the studies were unable to determine which dimension among the three defined by the UN and BPS had the significant impact on HDI, as they constructed models based on the indicators used for the interpretation of the dimensions. Therefore, a comprehensive analysis combining spatial regression and Structural Equation Modeling (SEM), known as spatial SEM, was deemed necessary. This is the reason the current study aimed to develop SERM-SEM modeling holistically. The model parameters were estimated using the Generalized Method of Moments (GMM). To assess spatial dependency, the Lagrange Multiplier (LM) method was employed, with a distinct model error distribution compared to the error distribution of the traditional spatial model. The result of the LM test development showed that, under the null hypothesis, the LM test statistics followed a distribution. The results of the SERM-SEM model development were applied to HDI modeling using data in 2022 with three latent variables, namely a Long and Healthy Life (LHL), Knowledge (Know_L), and a Decent Standard of Living (DLS) (based on UN standards). The assessment of the outer model in SEM was based on the loading factor values that exceed 0.5 and their significance. This evaluation aimed to identify indicators that effectively explained or measured latent variables, so it got the revised model in SEM. These indicators are LHL2 and LHL 4 to form LHL. DLS1 and DLS3 are indicators to make up DLS, and for Know_L, they are K2 and K3. The revised SEM model was analyzed using spatial. The results of the spatial dependency test showed that the HDI model significantly led to the SERM-SEM model. Knowledge and a decent standard of living variables significantly influence HDI.

Effective microgrid control for system recovery and restoring normal operation necessitates fast event detection and implementation of remedial action (if need arises). However, fast and reliable event detection in microgrids is challenging because of low observability and inconsistencies in measurements. A novel technique is proposed in the present work for the real-time event detection and to identify the various emerging abnormalities in the microgrid. The continuous energy signature using TKEO (Teager-Kaiser Energy Operator) of the continuous varying voltage and frequency signal are extracted through μPMU. REII (Robust Event Identification Index) is constructed from these energy signatures and based on its abrupt post-event deviation from the nominal values an event is flagged in the proposed method. The proposed method is data–driven and only depends on the real-time inputs through μPMUs thus it automatically adapts the uncertainties associated with the intermittent sources of energy in the microgrid under different operating conditions. The traditional event detection techniques fail in identification of abnormalities for a microgrid connected to the transmission systems and equipped with multiple DERs such as PVDG, WG etc. To address this challenge, an integrated microgrid with multiple DERs viz. PVDG, WG and a SG (Synchronous Generator) is first developed in this work. The complexity of simultaneous operation of a static generator i.e. PVDG along with a rotor-based generator such as WG and SG is handled by the modeling the dynamic controllers of PVDG and WG for their frequency and voltage control. The simulation results depict the efficiency, accuracy and robustness of the proposed technique in terms of estimation time, event accuracy and applicability in all types of events. Moreover, the presented methodology is also compared with the four AI/ML based methods to highlight the superiority of the method.

Authors:   Orel state agrarian University named after N. V. Parakhin, Finogentov V. N.
Published: April 2024

The article discusses the most common forms of relationships between the main sectors of culture (religion, science, morality, etc.): «dominance – subordination» and «equality, autonomy». It is shown that the predominance of certain forms of these relationships leads to the formation of various types of culture: monocentric culture, polycentric culture, «patchwork» culture. These types of culture are briefly described below. Such a variant of monocentric culture as a religio-centric culture is characterized in more detail. Special attention is also paid to the consideration of a polycentric culture formed on the basis of higher human values. It is emphasized that it is with such a variant of polycentric culture that humanity, most likely, should pin hopes for a more or less prosperous future.
Z. Freud, Zh. Lacan, and the dialectic of anxiety under capitalism
Authors:   EUSP, Markova Y. M.
Published: April 2024

The paper analyzes the functioning and role of the affect of anxiety in contemporary society from the point of view of the psychoanalytic theory of Sigmund Freud and Jacques Lacan, starting from statistical evidence of the ubiquity of anxiety disorders. Reconstructing the psychoanalytic theory of affect, the paper identifies two types of anxiety: realistic and neurotic. Capitalist society is characterized as provoking the growth of unconscious neurotic anxiety in response to the declining role of the Big Other and the disintegration of organic social ties. The paper outlines a model of dialectical interaction between neurotic and realistic anxiety under capitalism. Realistic anxiety about emerging dangers such as the COVID-19 pandemic is used by the media to deflect neurotic anxiety. This provides the modern media with a considerable resource for manipulating the population, and brings a temporary relief to the modern subject, who is suffering from the unconscious and formless anxiety caused by the very socio-economic structure of society.

Opinion polls show a high level of support for the Special military operation in Russian society. The main task is we have a rather limited knowledge about the peculiarities of social perception of changes in the everyday world which are the consequences of a Special military operation. The sphere of leisure takes a special place here because western sanctions changed the place and structure of vacation for Russians, restricted access to certain cultural products, sports events, and social networks. This article presents the results of a study of a hobby community of postcrossing - the swap of postcards. The purpose of the study was to determine the specifics of the perception of changes occurring in leisure practice under the influence of the Special military operation. The choice of the postcrossing community as the subject of research is determined by the fact that this type of leisure was originally formed as an international exchange of postcards, which is outside politics. After the start of the Special military operation, this hobby faced a significant restriction of postal communications between Russia and other countries and the politicization of participants in international swaps, which seriously affected leisure practices. The methodology of the study is quantitative and qualitative content analysis of posts and comments of thematic groups of the VK social network. According to the results, the peculiarities of the emotional perception of the changes taking place were established, three main models of leisure activities in new conditions were fixed, as well as the peculiarities of the semantic understanding of hobbies within each of them. The authors are sure that the information obtained on the postcrossing can be extrapolated to a wide range of other leisure social groups, both related to exchange, collecting (philately, philocarty, etc.), and mainly women's leisure groups (scrapbooking, embroidery, etc.). It helps us more adequately understand the specifics of the influence of the Special military operation on the leisure sphere in as a whole.
