Published: October 2023

One of the main methods in teaching deaf children effectively is through visualization of learning materials. Previous research has developed augmented reality-based interactive learning media for deaf children. However, these learning media have limitations related to smartphone memory, dependence on certain flashcards, and limited amount of material due to flashcard limitations. Here, researchers innovate to develop SIBI learning media applications based on deep learning technology that material does not depend on a specific flashcard, but the application is able to detect real objects and various images. TensorFlow Lite is considered lighter but still allows the system to run deep learning on mobile devices with low latency. This application is designed to capture a real object or image through the camera, then the object or image will be processed and recognized using TensorFlow Lite. The object recognition process is carried out at the classification layer using switch-case syntax and global class synchronization with the YouTube API. After the image or object is recognized, the system will issue an output in the form of an Indonesian sign language video link from the object.

Research on the Protection and Use of Personal Information: Focusing on the Problem of Excessive Protection
Authors:   National Association of Korean Local Government Studies, Choung Tae-Ok
Published: October 2023

Since the 1970s, with the advancement of information and communication technology, the creation and processing of data has been activated, and we are enjoying abundance unimaginable before that. This revolutionary change has been made possible because of the development of data processing technology and the freedom to create, process, and transfer data. However, as the importance of personal information protection is emphasized, prior consent for the collection, processing and transfer of personal information is being strengthened. In addition, it is reaching a level that hinders free distribution itself beyond the purpose of safe distribution of data through personal information protection. In order for the information society to develop normally, the smooth distribution of personal information is necessary. In the information society, as information and communication technology develop, not only information itself has value, but also new value is created by information. Information has value only when combined with personal information. For example, personal information is essential when trading stocks, managing banks, and buying and selling goods online. However, failure to properly manage data can easily expose an individual's privacy, resulting in various side effects. From a balance between the development of the data industry and personal information protection, institutional supplementation is needed to reduce excessive prior consent to personal information collection and transfer to third parties, widen the scope of alias processing, and strengthen post-responsibility as an alternative.

Published: October 2023

Akış deneyimi kişinin yaptığı işe kendisini tamamen vererek işin bir parçası gibi hissetmesi ve keyif alması anlamına gelmektedir. Okul müdürlerinin okul ortamında yaşadıkları akış deneyimlerini incelemeyi amaçlayan bu çalışma fenomenoloji deseninde tasarlanmıştır. Araştırmanın katılımcılarını ölçüt örnekleme yöntemiyle belirlenen 12 okul müdürü oluşturmuştur. Çalışmada veriler yarı yapılandırılmış görüşme formları aracılığıyla yüz yüze toplanmış ve betimsel analiz yöntemiyle çözümlenmiştir. Okul müdürleri kendilerini özgün kılan özellik olarak en çok iletişim becerilerine ve eğitim anlayışlarına dönük olarak en çok kültüre işaret etmiştir. Okul müdürleri günlük rutin işlerinin okul, denetim ve kontrol, bürokratik süreçler, aileler ve çevre temalarında gerçekleştiğini belirtmiştir. Bununla birlikte okul müdürleri okulda yapılacak işlerin net olduğunu ve kararların ortak alındığını düşünmektedir. Okulda yapılan en anlamlı iş olarak okul müdürleri öğrencilerle yaptıkları işlere dikkat çekerken potansiyellerini kullanmalarına engel olan işler olarak bürokrasi, eğitim dışı işler, veliler, bütçe ve yapısal/sistemsel işlere dikkat çekmiştir. Katılımcıların tümü öğrencilerin dâhil olduğu işlerde zaman algısının kaybolduğunu belirtmiştir. Okul müdürleri zaman algısını kaybettikleri işleri keyifli, verimli ve kaliteli olarak nitelendirirken öğrencilerin de keyif aldıkları durumlarda zaman algısını kaybettiklerini ifade etmişlerdir. Okul müdürleri kontrol sahibi oldukları durumlarda olumlu duygular içinde olduklarına ve kontrol sahibi olmadıkları durumlarda ise olumsuz duygular yaşadıklarına vurgu yapmıştır. Katılımcılar hedeflerine ulaştıklarında ve öğrencilerin başarılı olduğu durumlarda özgüvenlerinin, özsaygılarının ve kendilerine olan inançlarının geliştiğini belirtmiştir. Okul müdürleri motivasyon kaynakları olarak içsel motivasyonun önemine dikkat çekmiş ve okulu daha anlamlı kılacak önerilerde bulunmuşlardır. Araştırma sonuçları alanyazın ve eğitim politikaları bağlamında tartışılmıştır.

Discovery of A Large-scale Bent Radio Jet in the Merging Cluster A514
Authors: Lee Wonki , ZuHone John , James Jee M. , HyeongHan Kim , Kale Ruta , Ahn Eunmo
Published: October 2023

We report a discovery of a large-scale bent radio jet in the merging galaxy cluster A514 (z = 0.071). The radio emission originates from the two radio lobes of the active galactic nucleus (AGN) located near the center of the southern subcluster and extends toward the southern outskirts with multiple bends. Its peculiar morphology is characterized by a 400 kpc “bridge,” a 300 kpc “arc,” and a 400 kpc “tail,” which together contribute to its largest linear size of ∼0.7 Mpc. We find that both the flux and spectral features of the emission change with the distance from the AGN. Also, the “bridge” presents a 60% polarized radio emission, which coincided with an X-ray cold front. Based on our multiwavelength observations, we propose that A514 presents a clear case for the redistribution of an old AGN plasma due to merger-driven gas motions. We support our interpretation with idealized cluster merger simulations employing a passive tracer field to represent cosmic-ray electrons and find that merger-driven motions can efficiently create a cloud of these particles in the cluster outskirts, which later can be reaccelerated by the cluster merger shock and produce radio relics.

The Mekong River is the 10th largest river in the world. It is recognised as the most productive river in Southeast Asia and economically essential to the region, with an estimated 60-65 million people living in the lower Mekong Basin. The Mekong Delta within Vietnam is considered a highly vulnerable ecosystem under threat from increasing anthropogenic pressure, such as dam construction and, as a consequence, the Delta is sinking and altering the natural hydrological cycle. Dams also lead to eutrophication and pollution of downstream water from regulated water flux and water stagnation. Another threat is climate change coupled with the lower rainfall, which could lead to an increased risk of drought in the Mekong Delta Basin. Thus, these project data represent an important baseline reference. The ecological health of the Mekong Delta’s environment, as indicated by the quality and availability of its water and biological resources, largely determines the economic and social development of the region, which produces about half of the agriculture and aquaculture products of Vietnam.

This paper reports quantitative data on the biodiversity of six groups of aquatic organisms: bottom and pelagic fish, macrozoobenthos, microorganisms, phyto- and zooplankton in the Mekong Delta within Vietnam, as well as data on the physicochemical parameters of water and bottom sediments. The data were collected during 2018-2022 as part of the Ecolan E-3.4 programme within the framework of the research plan of the Joint Russian-Vietnamese Tropical Research and Technological Center. All presented datasets are published for the first time.

Published: October 2023

Pseudochironomini is a relatively small and poorly-studied tribe of subfamily Chironominae (Diptera, Chironomidae).

Pseudochironomus ruthae Andersen & Baranov sp. nov. is described and figured, based on a single male collected in a light trap at Matadero, Dominican Republic. The species can be separated from its congeners by the combination of the following characters: wing without dark bands, dorsocentrals in partly double row and apex of superior volsella rounded. The species is the first Pseudochironomus species to be formally recorded and described from the Caribbean. In addition, a new record of Manoa pahayokeensis Jacobsen & Perry, 2002 from the Dominican Republic is given. One specimen was DNA-barcoded and the barcode is given.
The Impact of Political Professionalization on Legislators-Citizens Congruence in Policies and Process Preferences
Authors: Vogel Lars
Published: October 2023

Cet article défend l’idée que la professionnalisation individuelle des parlementaires les désincite à adopter un comportement réactif et accroît la connivence qui existe entre eux. Ces mécanismes sont supposés affecter la convergence des points de vue entre les parlementaires et les citoyens en ce qui concerne leurs préférences en matière de politique et de processus. Nous testons ces hypothèses à partir du cas allemand en effectuant une analyse de correspondance exploratoire et des régressions sur des données issues d’une enquête conduite simultanément – et avec un questionnaire identique – auprès des parlementaires et des citoyens. L’analyse empirique contredit notre hypothèse pour la dimension gauche-droite, mais elle la corrobore partiellement pour la seconde dimension qui oppose le degré d’autonomie et d’hétéronomie des parlementaires dans les démocraties représentatives. L’effet de la professionnalisation individuelle est donc influencé par le degré de concurrence partisane. Si les partis sont en concurrence, la marge de manoeuvre pour des changements d’attitude et une convergence entre parlementaires est contrainte par les positions collectives de leurs propres partis.
Global dynamical behavior of solutions for finite degenerate fourth-order parabolic equations with mean curvature nonlinearity
Authors: Chen Yuxuan
Published: October 2023

In this work, the initial-boundary value problem for the global dynamical properties of solutions to a class of finite degenerate fourth-order parabolic equations with mean curvature nonlinearity is studied. With the help of the Nehari flow and Levine's concavity method, we establish some sharp-like threshold classifications of the initial data under sub-critical, critical and supercritical initial energy levels, that is, we describe the size of an initial data set. It requires the presumption that the initial data starting from one region of phase space have uniform global dynamical behavior, which means that the solution exists globally and decays via energy estimates that ultimately result in the solution tending to zero in the forward time. For the case in which the initial data corresponds to another region, we prove that the solutions related to these initial data are subject to blow-up phenomena in a finite time. In addition, we estimate the corresponding upper bound of the lifespan of the blow-up solution.

This article presents the results of a study on the effect of electrolyte-plasma cementation on the phase composition of the surface-modified layer and the mechanical properties of 20X steel using different solutions. It has been determined that electrolyte-plasma cementation followed by quenching in solutions containing (a) 10% calcined soda (Na2CO3), 10% urea (CH4N2O), 10% glycerin (C3H8O3) and 70% distilled water and (b) 10% calcined soda (Na2CO3), 20% urea (CH4N2O) and 70% distilled water, results in the formation of a modified structure on the surface of 20X steel. This structure mainly consists of the α-Fe phase, along with separate particles of reinforcing phases, Fe3C and Fe3C7 carbides and martensitic αx-Fe phase. The plasma of the electrolyte was used to heat the samples. Then these samples were partially immersed in the electrolyte and held at a temperature of 950 ℃ for 5 min, followed by quenching. As a result of this process, it was found that 20X steel exhibits higher hardness. After the electrolyte plasma cementation, it was observed that the friction coefficient of the modified surface of the steel samples significantly decreased. Additionally, the wear volume was reduced by more than 6.5 times compared to the initial state. The average microhardness after the electrolyte-plasma cementation is 660 HV, which is nearly four times higher than that of the initial material.
Stock returns and inflation expectations: Evidence from 20 major countries
Authors: Chiang Thomas C.
Published: October 2023

We examine the relation between stock market returns and inflation expectations using data for 20 advanced countries. Evidence reveals that a negative relation presents in each of 18 countries; the exceptions are Brazil and Russia. The uncertainty hypothesis is established via evidence that U.S. inflation positively increases equity market volatility (EMV), which has a negative impact on U.S. and global stock returns. Evidence leads to the conclusion that both expected domestic inflation and EMV have adverse impacts on stock returns. The model is robust with different formations of inflation expectations and whether the test equations are examined using nominal or real stock returns.
Physics Teacher Agency for Physics Education
Authors: KIM Min-Seong
Published: October 2023

In the field of middle and high school physics education, teachers must succeed in both “physics education” and “physics as education.” This is because the school classroom is not just a time for learning physics, but also a time for connecting physics to students’ lives “Right here Right now” as an education. Physics teachers are actively interpreting and reconstructing the field with students who change rapidly in society and creating the context of physics education. In this personal and social context, teacher agency is exerted.1) Teacher agency is not just the personal ability of individual teachers to implement policies sincerely or the policies promoted by higher institutions. Teacher agency as a change agent is achieved by creating an environment in which teachers can actively demonstrate their expertise with their own beliefs in a context that encompasses both the personal and social structural dimensions of teachers.2) In order to promote the emergence of physics teacher agency, educational administrative agencies should focus not only on promoting education policies that focus on the individual competencies of teachers, but also on creating a structural context around teachers and teacher networks as important agent in the development and implementation of education policies. The Korean Physical Society, which plays an important role in the development of physics education, needs to expand opportunities for participation in physics education by physics teachers to help expand the network of physics teachers, who are important actors in the network of physics education.

Se han definido varias aportaciones no-materiales de los glaciares del Aneto y Maladeta en el Parque Natural de Posets-Maladeta (PNPM), teniendo en cuenta la clasificación de la Plataforma Intergubernamental sobre Biodiversidad y Servicios de los Ecosistemas (IPBES por sus siglas en inglés). Se ha realizado un estudio desarrollado a través de una encuesta respondida por 121 personas conocedoras del PNPM. A su vez, se ha inferido la incidencia de los glaciares en el paisaje local realizando cálculos de cuencas visuales mediante un SIG. Los resultados muestran que entre 2020 y 2050, la importancia de las contribuciones no-materiales de los glaciares disminuirá especialmente en las experiencias físicas y psicológicas en el entorno de los glaciares, así como en el conocimiento e inspiración, debido a la pérdida de un elemento geográfico de gran valor científico y educativo. Finalmente, se discuten las posibles consecuencias de la desaparición de los glaciares, sobre el atractivo del PNPM, el flujo de visitantes, la economía del valle, así como sobre la importancia de implementar estrategias de adaptación que garanticen la resiliencia en el contexto del cambio global.
The Middle East and Eastern Africa Intersected: Discussing contemporary connections
Authors: Ajú Miguel Mbiavanga , Ylönen Aleksi
Published: October 2023

Historically, the interaction between the Middle East and Eastern Africa has resulted in mutual penetration of cultural, economic, and political influences. In more recent times, it is assumed that the Middle East has influenced Eastern Africa more. Do the distinct regional traits, and what are currently considered asymmetrical relations, eliminate the possibility of developing equal and mutually respectful relationship between the two different but deeply intertwined regions? To answer this question and attempt to contribute to the debate on the intersection and the dynamics underpinning contemporary relations, we explore links between the two regions through historically conscious reflections. We argue for leveraging productively on the complex and deeply entrenched inter-regional ties by engagement based on equality, respect, and mutual benefit.
A Critical Appraisal of Realist International Relations Concepts in the Horn of Africa-Persian Gulf Relations: The state, power, and agency
Authors: Ylönen Aleksi
Published: October 2023

International Relations literature (re)produces principally “realist” depictions of relations between the Horn of Africa and the Persian Gulf. It portrays states as monolithic actors and the Persian Gulf countries as superior according to a state-centric conception of power and fails to recognize the agency of various African state and non-state actors and understand power in their external relations. This article discusses caveats of the key concepts of the realist approach and argues that it provides an inadequate analytical frame when applied to the Horn of Africa-Persian Gulf relations. The article calls for a broader approach that enables a better understanding of multiple actors that engage in international relations, enabling a more accurate analysis that helps to improve both theory and practice.
The Limits of Hegemonic Regionalism for Explaining Region-Building: A counter-hegemonic reading of the Red Sea Council
Authors: Sánchez Victoria Silva
Published: October 2023

In the last few years, the Red Sea has witnessed unprecedented attention from scholars and policymakers. However, this does not preclude the fact that it has held enormous importance for the actors surrounding it long before. Yet, it has never qualified as a region due to a worldview deployed by hegemonic regionalism that determines what qualifies as a region. This article seeks to explain why hegemonic regionalism is ill-suited to explain regionalism in the Red Sea. We propose a theoretical framework establishing the distinct elements of hegemonic regionalism and how they have been countered by other perspectives. Then we turn towards the Red Sea Council to discuss its emergence and how it challenges the key elements of hegemonic explanations.
Intimate Connections: Marriage and mobilities across the modern Mediterranean and the Red Sea
Authors: Bruzzi Silvia
Published: October 2023

The prism of marriage can be a unique opportunity to write a social and cultural history in the modern Mediterranean and the Red Sea. The progressive dissolution of the Ottoman Empire, followed by the different settings of colonial encounters and/or the nation-building processes, led to the reform and reordering of multiple and contemporary marriages practices in a complex and dense imperial space such as the Mediterranean and the Red Sea regions. Legal regulations of marriage in the (post)Ottoman space are the results of superpositions, interactions and convergences of multiple juridical practices and norms, that included religious, customary, and civil regulations. Here, mobility played a crucial role in establishing and breaking new conjugal bonds, thus tracing the intimate entanglements between the Mediterranean and the Red Sea.
A História de Luta de Maria Henriqueta Miguel Pedro na FNLA, Frente Nacional de Libertação de Angola
Authors: Paredes Margarida
Published: October 2023

O artigo debruça-se sobre a história de vida da ex-combatente da FNLA, Maria Henriqueta Miguel Pedro, Joia. Joia foge aos estereótipos sobre a FNLA. De origem kimbundu, filha de pais assimilados, nasceu em Luanda e foi estudante liceal. A sua biografia contribui para pensarmos a FNLA para além da História Única, ou seja, um movimento nacionalista de homens da etnia bakongo, com origem no norte de Angola, refugiados no país vizinho Congo, de religião batista e com raízes camponesas. O artigo defende que as ex-combatentes e a militância clandestina devem ser incluídas na memória e história da luta de libertação da FNLA para que essa luta seja ressignificada e a pertença à nação não seja excludente das mulheres.

Anchored on the social exchange theory, this chapter examines the indirect effect of employee engagement on the relationship between high-performance work practices (HPWPs) and employee performance in a public higher education context. The participants were select teaching and non-teaching personnel of a public state university in the Philippines (n = 200). The results of using a predictive research approach and partial least squares (PLS) path modeling using WarpPLS 8.0 revealed that HPWPs have a significant and direct effect on employee engagement and performance. Moreover, employee engagement was found to have a considerable impact on employee performance, and act as a mediator on the relationship between HPWPs and employee performance. Both practical and theoretical implications were provided in this study.

Self-propagating intermediate temperature synthesis (SIS) is a process that utilizes exothermic reactions to initiate and maintain component combustion so as to produce low porosity values and high hardness. It is necessary to know about the heat transfer phenomenon because SIS has a weakness, namely the high exothermic rate and very fast combustion rate which requires a high level of control. In addition, compression or compaction needs to be done because this method is expected to produce a homogeneous particle density distribution. The phenomenon of heat transfer and pressure that occurs in the SIS process is a simplification of the self-propagating high-temperature synthesis (SHS) process, which can be simulated and analyzed using engineering software based on finite element analysis. Stress simulation that occurs with the addition of weight percent titanium 5%, 10% and 20% using a pressure of 171 MPa and produces a normal stress. The heat transfer simulation that occurs uses a temperature of 750 °C, 850 °C, and 950 °C with a processing time of 2 hours with variations in the addition of weight percent titanium 5%, 10%, and 20% which results in an effect on heat flux and temperature distribution. Samples that were given the addition of 20% titanium by weight were given a pressure of 171 MPa to produce a normal stress of-230.44 MPa with the lowest porosity value of 22.63%. Samples processed at 850 °C with the addition of 10% weight percent titanium produced the lowest heat flux value of 0.0027220 W/m2.
a-Si EPID Modeling in GATE for Monte Carlo Investigation on the Optical Properties of Gd2O2S:Tb and Lu2SiO5:Ce Scintillators

Published: October 2023

A detailed a-Si Electronic Portal Imaging Device (EPID) was implemented in GATE (Geant4 application for tomographic emission) toolkit for Monte Carlo simulations, employing the standard electromagnetic processes and optical photon processes. The composition of the scintillating material is varied using the conventional terbium-doped gadolinium oxysulfide phosphor (Gd2O2S:Tb) and cerium-doped lutetium oxyorthosilicate (Lu2SiO5:Ce) which is widely used in Positron Emission Tomography (PET) detectors due to its supremacy in aiding the detection of low-energy photons. It was found that the number of optical photons produced is higher when using the Lu2SiO5:Ce scintillator resulting in a slightly better signal-to-noise ratio (SNR). The scattering within the EPID components was also investigated where the majority of the detected secondary particles were created in the scintillator. The results also show that the copper plate layer of the EPID contributes to additional Compton electrons and bremsstrahlung and annihilation photons to the measurements in the scintillator and photodiode layer. The glass substrate, graphite plates, electronic components, and aluminum bottom cover are also found to contribute a huge fraction of backscattered particles to the measurements at the photodiode layer.
