Os cistos residuais são definidos como cistos inflamatórios, revestidos por epitélio e em seu interior apresentam um conteúdo semifluido ou fluido, que em sua dominância ocorrem na maxila. Em geral não apresentam sintomas e se não tratado corretamente pode ocasionar uma reabsorção óssea e enfraquecimento da maxila ou mandíbula. O principal objetivo deste trabalho é relatar o caso de uma paciente do sexo feminino, que compareceu a Clinica Odontológica relatando um cisto na região dos incisivos centrais superiores. No exame clinico, notou-se um aumento de volume na porção vestibular do processo alveolar, sendo sua consistência macia e sintomatologia dolorosa a palpação. Portanto, optou-se por sua  enucleação cirúrgica da lesão, seguida de uma minuciosa descontaminação mecanica e quimica, seguida de regeneração óssea guiada utilizando um enxerto ósseo sintético a base de fosfato de cálcio e hidroxiapatia sendo seu diagnóstico confirmado através de exame histopatológico. Contudo neste relato pode-se observar que a enucleação do cisto residual seguida por uma boa descontaminação mecanica e quimica, associado a regeneração óssea guiada se mostrou eficaz no tratamento deste caso, não ocorrendo recidivas no periodo de acompanhamento.

Published: April 2023

Injection coupling is a well-known cause of high-frequency combustion instability in hydrogen/liquid oxygen ([Formula: see text]) rocket engines. This type of instability is commonly explained by the two-way coupling between the dynamics of the combustion chamber and the injection system. Recent experimental studies of the BKD combustor, however, suggest that the LOX injector could be self-excited and driving the acoustic mode of the combustion chamber. To assess the feasibility of this mechanism, here, we study both experimentally and theoretically the acoustic stability of the LOX injector isolated from the combustion chamber. The experimental study was performed in a water facility mimicking the conditions of a single LOX injector. The water injector was then modeled using an acoustic network analysis, where the transfer matrix of the LOX injector inlet orifice was computed numerically using a linear approach. The analysis successfully predicts the experimental peak in unsteady pressure, revealing that the LOX injector can be self-excited. The instability was found to be driven by the whistling of the orifice at the inlet of the injector coupled with the second longitudinal acoustic mode of the LOX post tube.
Numerical Investigation of Film Coefficient Approximation for Chemically Reacting Boundary-Layer Flows
Authors: Cooper Justin , Salazar Giovanni , Martin Alexandre
Published: April 2023

Aerothermal analysis of spacecraft planetary entry is heavily dependent on heritage engineering models. The film coefficient heat transfer model examined in this paper estimates the convective heating to the vehicle for a laminar, dissociated, chemically reacting boundary layer for an Earth atmosphere. This model requires information about the vehicle and flowfield for a given trajectory point and estimates a proportional relationship between enthalpy potential and convective heat flux. In practice it is the aerothermal engineer who must decide which assumptions are appropriate for his/her application. This work looks at numerous CFD simulations for an arbitrary, axisymmetric flight vehicle to analyze the relative importance of both the mass and energy constraints imposed at the wall boundary, as well as the effect of various diffusion models. Within the subset of tested energy boundary conditions, it is found that the most desirable energy boundary condition is the radiative equilibrium boundary condition, which permits conservative estimates of convective heat flux, but also generates flowfield-dependent spatial thermal distributions along the surface. Other key findings are presented in an effort to make the film coefficient engineering model readily available to design engineers across industry.

Published: April 2023

The development of the water management system has so far reached the stage of utilizing IoT technology in the monitoring and operation process. An essential factor in water that affects the quality of a substance is pH. The research aims to analyze and ensure that the devices have a small pH measurement error rate with TLC4502 & E201C. The calibration process was carried out using linear regression, and  value of 0.99 was obtained. Analysis was carried out using one-way ANOVA and Tukey HSD methods, and it was found that all data pairs rejected the null hypothesis (H0) and accepted the alternate hypothesis (H1). This hypothesis indicated a significant difference in the relative measurement error of pH in each condition. The standard error value of each measurement after filtration was 0.00, with an uncertainty value ranging from 0.07 to 0.02. If the sensor can provide measurement results with low error and high accuracy, then the sensor can be widely circulated and used. Through this research, the feasibility of a measuring instrument was developed based on the perspective of errors and high accuracy. A quality measuring instrument certainly helpful in various fields from the fisheries, hydroponics, and environmental sectors.
Advantages and Limitations of Hydrogen Peroxide for Direct Oxidation of Methane to Methanol at Mono-Copper Active Sites in Cu-Exchanged Zeolites
Authors: Cheng Lu , Chen Xuning , Hu P. , Cao Xiaoming
Published: April 2023

The performance of the direct oxidation of methane to methanol (DMTM) is significantly influenced by the oxidant. It is still incredibly challenging to realize one-pot DMTM using dioxygen. So far, hydrogen peroxide is still the most frequently reported green oxidant for DMTM with a high selectivity for methanol. To achieve insights into the influence of oxidants on the DMTM performance, we computationally investigated the reaction mechanisms of DMTM using hydrogen peroxide at mono-copper sites in three kinds of Cu-exchanged zeolites with different sizes of the micropores. We identified the common advantages and limitations of hydrogen peroxide as the oxidant. In contrast to dioxygen, the O-O bond of hydrogen peroxide could be easily broken to produce reactive surface oxygen species, which enables the facile C-H bond activation of methane at a lower temperature. However, because of the radical-like process for C-H bond activation at mono-copper sites, it is kinetically challenging to actualize the preferential C-H bond activation of methane as compared to that of methanol. Moreover, the lower O-H bonding energy of hydrogen peroxide would result in the self-decomposition of hydrogen peroxide. Despite the bottlenecks, the kinetic analysis shows that it is still promising to improve catalysts to boost the performance of DMTM using hydrogen peroxide.
From Particle-in-a-Box Thought Experiment to a Complete Quantum Theory?
Authors: Chen Jixin
Published: April 2023

It is an unavoidable question raised by Albert Einstein if quantum theory is complete. In this manuscript, I speculated that the energy density distributions along space and time in a quantum system are uniform according to the 1st law of thermodynamics. Thus, the complementary energy contributions are added to the classical solutions of the 1D particle in a box problem, making the energy density a complex distribution function over space and time. Then the concept is extended to the free rotation problem with a Hamiltonian slightly different than the classical Schrödinger equation. The picturized energy distribution functions and associated time evolution are described in movies for comparison between example classical wave functions and the energy density functions. The wave functions for the hydrogen atom are then guessed based on the historical solutions. Can this assumption on energy distribution and the poor math in this manuscript lead to a complete quantum theory?
Deciphering methylation effects on S2(pp*) internal conversion in the simplest linear alpha,beta-unsaturated carbonyl
Authors: Chakraborty Pratip , Couto Rafael , List Nanna Holmgaard
Published: April 2023

Chemical substituents can influence photodynamics by altering the location of critical points and topography of the potential energy surface (electronic effect) and by selectively altering the inertia of specific nuclear modes (inertial effects). Using non-adiabatic dynamics simulations, we investigate the impact of methylation on S2(pp*) internal conversion in acrolein – the simplest linear alpha,beta-unsaturated carbonyl. Consistent with time constants reported in a previous time-resolved photoelectron spectroscopy study, S2/S1-deactivation occurs on an ultrafast timescale (~50 fs). However, our simulations do not corroborate the sequential decay model used to fit the experiment. Instead, upon reaching the S1 state, the wavepacket bifurcates: a portion undergoes ballistic S1/S0-deactivation (~80 fs) mediated by fast bond-length alternation motion, while the remaining decays on the ps-timescale in a more statistical regime. Our analysis reveals that methyl substitution, generally assumed to mainly exert inertial influence, also manifests in important electronic effects due to its weak electron-donating ability. While methylation at the beta C-atom gives rise to effects principally of inertial nature, such as retarding the twisting motion of the terminal -CHCH3 group and increasing its coupling with pyramidalization, methylation at the alpha or carbonyl C-atom modifies the potential energy surfaces in a way that also contributes to alterating the late S1-decay behavior. Specifically, our results suggest that the factor-of-two slowing of the ps-component upon alpha-methylation is a consequence of a tighter surface and reduced amplitude along the central pyramidalization, effectively restricting the access to the S1/S0-intersection seam. Our work offers new insight into the S2(pp*) internal conversion mechanisms in acrolein and its methylated derivatives and highlights site-selective methylation as a tuning knob to manipulate photochemical reactions.
Accurate calculation of many-body energies in water clusters using a classical geometry-dependent induction model
Authors: Herman Kristina M. , Stone Anthony J. , Xantheas Sotiris S.
Published: April 2023

We incorporate geometry-dependent distributed multipole and polarizability surfaces into an induction model that is used to describe the 3- and 4-body terms of the interaction between water molecules. The expansion is carried out up to hexadecapole with the multipoles distributed on the atom sites. Dipole-dipole, dipole-quadrupole, and quadrupole-quadrupole distributed polarizabilities are used to represent the response of the multipoles to an electric field. We compare the model against two large databases consisting of 43,844 3-body terms and 3,603 4-body terms obtained from high level ab initio calculations previously used to fit the MB-pol and q-AQUA interaction potentials. The classical induction model with no adjustable parameters reproduces the ab-initio 3- and 4-body terms contained in these two Databases with a Root-Mean-Square-Error (RMSE) of 0.104/0.058 and a Mean-Absolute-Error (MAE) of 0.054/0.026 kcal/mol, respectively, results that are on a par with those obtained by fitting the same data using tens of thousands of Permutationally Invariant Polynomials (PIPs). This demonstrates the accuracy of this physically motivated model in describing the 3- and 4-body terms in the interactions between water molecules with no adjustable parameters. The triple-dipole-dispersion energy was included in the 3-body energy and was found to be small but not quite negligible. The model represents a practical, efficient and transferable approach for obtaining accurate non-additive interactions for multi-component systems without the need of performing tens of thousands of high level electronic structure calculations and fitting them with tens of thousands of PIPs.
Novel Electrochemical Biosensing Strategy for Antibody IgG detections
Authors: Patel Amit , Sharma Rahul
Published: April 2023

The human immune system is a complex network of cells, tissues, and organs that work together to protect the body from harmful pathogens. Antibodies, also known as immunoglobulins (Ig), are small proteins that play a vital role in the immune system's defense mechanism. Among the five classes of immunoglobulins, Immunoglobin G (IgG) is the most abundant and widely studied. This article provides an in-depth overview of the basics of IgG, including their chemical and physical properties and their roles in the human immune system. The article then focuses on the critical biosensor working principles with an emphasis on electrochemical biosensors. Biosensors are analytical devices that convert a biological response into an electrical signal, allowing for rapid and sensitive detection of specific analytes. The use of biosensors for IgG detection has gained significant attention in recent years due to their sensitivity, specificity, and ability to detect IgG in real-time. This article also discusses many novel strategies that have been reported in the literature for sensitive IgG detection. These strategies include the use of different biorecognition elements, such as antibodies, aptamers, enzymes, and biomimetic materials. Moreover, the article concludes by highlighting recent research advances and future directions for sensitive IgG detection, such as the use of nanomaterials and adaptable machine learning models, leading to a more efficient method of IgG detection.
Exploring CO2 Hydrogenation to Methanol at a CuZn--ZrO2 Interface via DFT Calculation
Authors: Lempelto Aku , Gell Lars , Kiljunen Toni , Honkala Karoliina
Published: April 2023

Multi-component heterogeneous catalysts are among the top candidates for converting greenhouse gases into valuable compounds. Combinations of Cu, Zn, and ZrO2 (CZZ) have emerged as promisingly efficient catalysts for CO2 hydrogenation to methanol. To explore the catalytic mechanism, density functional theory (DFT) calculations and the energetic span model (ESM) were used to study CO2 conversion routes to methanol on CuZn-ZrO2 interfaces with a varying Zn content. Our results demonstrate that the presence of Zn sites at the interface improves CO2 binding. However, the adsorption and activation energies are insensitive to Zn concentration. The calculations also show that the hydrogenation of adsorbate oxygen atoms at the interface is kinetically more favourable and requires hydrogen spillover from the metal to the zirconia. This leads to barriers that are lower than those reported on interface or metal-only sites in previous literature. While DFT calculations alone are unable to identify which one of the competing pathways is more favourable, the ESM model predicts that the carboxyl pathway has a higher turnover frequency than the formate route. Our findings also show the importance of considering effects such as hydrogen spillover which take place at a metal-oxide interface when modelling complex catalytic environments.

Species Selection for Automatic Chemical Kinetic Mechanism Generation
Authors: Johnson Matthew S. , Pang Hao-Wei , Liu Mengjie , Green William H.
Published: April 2023

Many important chemical kinetic systems require detailed chemical kinetic models to resolve. These detailed kinetic models can involve thousands of species and hundreds of thousands of chemical reactions making them difficult to construct by hand. Modern automatic mechanism generation algorithms can mostly be divided into two classes: rule and rate based. Rule based generators choose species based on user defined constraints on species and reaction classes. Rate based generators generate a much larger set of potentially important species and reactions and then choose which ones to add based on running simulations of species and reactions deemed important and calculating the flux to potentially important species. In principle, the latter is preferable as it requires the user to make far fewer assumptions about what is important in the system. However, while the effectiveness of the rate-based approach has been demonstrated in a wide variety of systems, it has also been demonstrated to have difficulty picking up important low flux chemistries. Here we present a discussion of the challenges associated with rate-based mechanism generation and new algorithms that are able to efficiently mitigate these challenges in a set of case studies.
The system for near-real time air pollution monitoring over cities based on the Sentinel-5P satellite data
Authors: Savenets Mykhailo , Oreshchenko Andrii , Nadtochii Liudmyla
Published: April 2023

Introduction. Air pollution heterogeneity and rapid urbanization impose numerous constraints on available near-surface air quality monitoring. The solution for effective warning comes with the integration of different data, including remote sensing. Satellite data cannot answer whether dangerous pollution levels are observed; however, it provides a complete picture and may detect air pollution transportation towards or away from cities. The possibilities for effective near-real time (NRTI) monitoring have significantly improved with the launch of the Sentinel-5P satellite. The study aimed to describe the developed system for NRTI air pollution monitoring over Kharkiv, Kryvyi Rig, Kyiv, and Odesa based on NO2 and CO data derived from the Sentinel-5P satellite.

Data and methodology. The NRTI System was developed for tropospheric NO2 and total CO column number densities based on the Sentinel-5P NRTI products. After satellite scanning of Ukrainian territory, the NRTI System goes live in 2-3 hours. It is fully automatic, and modules were written using Python, VB.NET, and batch-scripting.

Results. The NRTI System includes four main phases: preparatory, source data downloading, processing and post-processing with visualization, archiving, and result distribution among users. Source data filtering with a quality assurance index and downscaling with linear kriging interpolation were developed. The output of the NRTI System is data in regular grids with a spatial resolution of 0.02o×0.02o. Based on the NRTI System work during October – December 2021, we conducted preliminary analyses to understand the possibilities of data usage. Higher NO2 content was observed in Kyiv and Kharkiv, where traffic emissions play a crucial role in air quality worsening. The use of daily time series allowed the detection of an increase in NO2 variance during the heating season, as well as plume distribution from cities to rural areas due to the prevailing wind. CO content is more homogeneous; however, higher values were observed in industrial Kryvyi Rig and Odesa. It is emphasized the huge impact of shipping CO emissions on air quality in Odesa. The temporal averaging of the NRTI System output allowed us to define the most polluted districts within the cities of interest. We intend to continue developing the presented NRTI System and develop the same algorithms for all cities with populations greater than 500 000 people in order to provide operational air pollution monitoring based on satellite data.

Enhanced PBFT Blockchain based on a Combination of Ripple and PBFT (R-PBFT) to Cryptospatial Coordinate
Authors: Wibowo Achmad Teguh , Hariadi Mochamad , Suhartono Suhartono , Shodiq Muhammad
Published: April 2023

In this research, we introduce the combination of two Blockchain methods. Ripple Protocol Consensus Algorithm (RPCA) and Practical Byzantine Fault Tolerance (PBFT) are applied to cryptospatial coordinates to support cultural heritage tourism. The PBFT process is still used until the preparation process to ensure a maximum error of 33%, and every node would add a new chain in all nodes, so PBFT has a slower processing speed than other methods. This research cuts the PBFT process. After the preparation process in PBFT, the data was entered into the RPCA node and was calculated using an equation to minimize errors with a maximum limit of 20%. After this process, the was were sent to the commit process to store the data in all connected nodes in the Blockchain network; we call this combination of two methods R-PBFT. Combining the two methods can enhance data processing security and speed because it still uses the PBFT work combined with the speed of RPCA. Furthermore, this method uses a fault tolerance value from the RPCA of 20% to enhance data processing security and speed.

Authors: Karpunin Ihor
Published: April 2023

The article shows that the issue of obtaining a reliable forecast in the process of analyzing the solvency of any business entity (enterprise, company, etc.) is still relevant. Such tasks, related to forecasting and analysis of the obtained results, allow specialists to talk about the stability or instability of the relevant entity. And this, in turn, can be important for evaluating, for example, the investment attractiveness of the object of analysis and evaluation from the point of view of its financial condition (FC). Considering the rapid development of information technologies, it is shown that the possibility of the usage of new cognitive systems and technologies in the process of FC assessment and forecasting is interesting for study. The article proposes a mathematical model of the description in the conceptual and functional aspect of the process of formation and application of the knowledge base for the decision support system during the assessment of the financial condition of the enterprise/company for circumstances related to the identification of individual factors that are weakly structured. In turn, this allows for increasing the understanding of the analyzed economic processes related to the FC of business entities.
COMPLEX METHOD FOR AUTOMATIC RECOGNITION OF NATURAL LANGUAGE AND EMOTIONAL STATE
Authors: Iosifov Ievgen
Published: April 2023

Current trends in NLP emphasize universal models and learning from pre-trained models. This article explores these trends and advanced models of pre-service learning. Inputs are converted into words or contextual embeddings that serve as inputs to encoders and decoders. The corpus of the author's publications over the past six years is used as the object of the research. The main methods of research are the analysis of scientific literature, prototyping, and experimental use of systems in the direction of research. Speech recognition players are divided into players with huge computing resources for whom training on large unlabeled data is a common procedure and players who are focused on training small local speech recognition models on pre-labeled audio data due to a lack of resources. Approaches and frameworks for working with unlabeled data and limited computing resources are almost not present, and methods based on iterative training are not developed and require scientific efforts for development. The research aims to develop methods of iterative training on unlabeled audio data to obtain productively ready speech recognition models with greater accuracy and limited resources. A separate block proposes methods of data preparation for use in training speech recognition systems and a pipeline for automatic training of speech recognition systems using pseudo marking of audio data. The prototype and solution of a real business problem of emotion detection demonstrate the capabilities and limitations of owl recognition systems and emotional states. With the use of the proposed methods of pseudo-labeling, it is possible to obtain recognition accuracy close to the market leaders without significant investment in computing resources, and for languages with a small amount of open data, it can even be surpassed.

Looking at information and telecommunication networks, we see that the transmission of confidential data via the Internet is becoming more frequent every day, and therefore, it is necessary that our data be reliably protected from various threats, vulnerabilities that every day try to gain access to the network and intercept data, neutralize, gain access to network resources. That is why, in our time, protecting data, software and hardware from viruses and various vulnerabilities is more necessary than ever, and not just a problem. Based on these considerations, it is necessary both to create new methods for protecting information and telecommunication networks, and to improve existing ones for better network security, because one of the important elements of information protection is network protection itself. Taking into account the constantly growing statistics of cyber attacks on information and telecommunication networks, after in-depth analysis and processing of the mentioned issues, the authors of the article highlighted the current state of ensuring the security of information and telecommunication networks and solutions regarding security in information and telecommunication networks. The authors comprehensively covered and investigated the problems of ensuring security in information and telecommunication networks, conducted an analysis of threats and vulnerabilities that harm the information network, and conducted research on methods of countering modern threats to information and telecommunication networks. Attention is also paid to the development of security solutions in the information and telecommunications network. The authors plan a number of scientific and technical solutions for the development and implementation of effective methods for detecting vulnerabilities and means for ensuring the requirements, principles and approaches for ensuring the security of information and telecommunication networks.
Özel alan yeterlilikleri bağlamında Türkçe öğretmeni adaylarının Türkçe öğretmenliğine ilişkin görüşleri
Authors: AHISKALI Eylem Ezgi
Published: April 2023

Dünyada olduğu gibi Türkiye´de de yaşanan bilgi ve iletişim çağı eğitim alanında büyük değişim ve dönüşümlere neden olmakta ve bireylerin sahip olması gereken nitelikler çeşitlenmektedir. Bu niteliklerin kazandırılmasında en önemli rol, eğitim ve öğretim sürecindedir. Bu nedenle öğrencilere ve topluma bu becerilerin kazandırılmasında öğretmenlere pek çok sorumluluk düşmektedir. Bu kapsamda MEB 2017 yılında “Öğretmenlik Mesleği Genel Yeterlikleri” çerçevesini yayınlamış ve ardından öğretmenlik alanları bazında öğretmenlerin özel alan yeterliklerini belirlemiştir. Türkçe öğretmenleri için de MEB (2017) tarafından “Türkçe Öğretmeni Özel Alan Yeterlikleri” sunulmuştur. Diğer tüm derslerin temelini oluşturan Türkçe dersini yürütecek Türkçe öğretmeni adaylarının Türkçe öğretmenliğine ilişkin görüşlerini özel alan yeterlikleri bağlamında değerlendirmenin amaçlandığı bu çalışmada, nitel araştırma yöntemlerinden biri olan durum çalışması kullanılmıştır. Araştırmanın çalışma grubunu 2022-2023 eğitim-öğretim yılında bir devlet üniversitesinin Türkçe Eğitimi bölümünde öğrenim gören 50 dördüncü sınıf öğrencisi oluşturmaktadır. Veri toplama aracı olarak araştırmacı tarafından geliştirilen yapılandırılmış görüşme formu kullanılmış ve elde edilen veriler, betimsel analiz tekniğiyle analiz edilmiştir. Araştırmanın sonunda Türkçe öğretmeni adaylarının görüşlerine göre “Türkçe Öğretim Sürecini Planlama ve Düzenleme, Dil Gelişimini İzleme ve Değerlendirme ve Türkçe Alanında Mesleki Gelişimini Sağlama” özel alan yeterliklerinin bazı alt boyutlarında eksikliklerinin olduğu belirlenmiştir. “Dil Becerilerini Geliştirme ile Okul, Aile ve Toplumla İş Birliği Yapma” özel alan yeterliği alt boyutlarında ise eksikliklerinin olmadığı belirlenmiştir. Bu sonuçlardan hareketle Türkçe öğretmeni adaylarının mesleklerine ilişkin özel alan yeterliklerinin çoğunun farkında olduğu, eksik olan yeterliklerinde ilgili izlencelere eklenip giderilmesi gerektiği söylenebilir. Bu değerlendirmelere göre yapılan çalışmanın ilgili alanyazına, eğitim fakültelerinin ilgili bölümlerine ve yeni öğretmen yetiştirme programlarının oluşturulmasına güncel katkı sağlayacağı düşünülmektedir.
أهمية الاختبارات للناطقين بغير
Authors: ALDYAB Ahmed
Published: April 2023

تعد الاختبارات إحدى الوسائل التي يمكن أن تقيس مستوى الطالب، فالاختبار هو عنصر يلازم العملية التعليمية ويقوم بتحديد مستوى الطالب وتقدمه. ولا شك أن تعليم اللغة العربية للناطقين بغيرها يمثل تحدياً من أوجه مختلفة من أهمها إعداد الاختبارات المناسبة والتي تعتمد على أساس علمي مدروس وهذا ما ينقص الجامعات والمعاهد في اختباراتها. أهداف البحث: سيسعى البحث للكشف عن السلبيات والإيجابيات في إعداد الاختبارات من خلال تجارب بعض الجامعات التركية، وإعطاء بعض الأفكار والمقترحات التي يمكن أن تساعد في تنظيم وجعل الاختبارات أكثر معيارية ومنهجية. مشكلة الدراسة: يأتي هذا البحث ليضع يده على مشكلة وهي قلة اختبارات اللغة العربية للناطقين بغيرها وتخلفها في ضوء معايير الكفاية والكفاءة اللغوية، فمشكلة الدراسة تبرز في نقطتين رئيسيتين، الأولى: قصور الاختبارات اللغوية في تحديد مستوى الطلاب، والنقطة الثانية عدم كفايتها كنموذج وعدم شمولها كتنوع وتعدد. منهجية البحث: سيعتمد البحث على المنهج الوصفي كقراءة في مستوى الاختبارات وتنوعها وتعددها، وسيختار الباحث خمساً من الجامعات التركية التي لها باع في تعليم اللغة العربية للأتراك. وبعد ذلك سيقوم الباحث باتباع أسلوب التحليل لإظهار السلبيات والإيحابيات في هذه الاختبارات. عينة الدراسة: سيختار الباحث خمساً من الجامعات التركية وهي جامعة أنقرة، وجامعة غازي وجامعة أرض روم وجامعة بورصة وجامعة إسطنبول. حدود الدراسة: - الحدود المكانية: سيكون الإطار المكاني محدداً بمناطق مختلفة من تركيا، فسيختار جامعة تقع في غرب تركيا وجامعة تقع في وسط تركيا وجامعة في الشرق وجامعة في الجنوب وجامعة تقع على الساحل الإقليمي. وقد قصدت إلى ذلك لأن الطلاب يختلف عندهم تعلم العربية بسبب عدة عوامل أهمها الجغرافيا وعناصر التطور والتركيبة السكانية. - الفئة المستهدفة: سيختار الباحث طلاب كليات الشريعة والأدب العربي وكليات تعليم اللغة العربية وبمستويات مختلفة. محاور البحث: سينقسم البحث إلى ثلاثة محاور رئيسية، القسم الأول سيكون عبارة عن استبيان يجريه الباحث على الجامعات المذكورة، القسم الثاني سيقوم الباحث بتحليل الاختبارات من خلال الاستبيان وفق المنهج التحليلي، القسم الثالث سيجري الباحث مقارنة بين اختبارات الجامعات المذكورة لإظهار الاختبارات المنهجية والأقرب لأن تكون معيارية.
ABİLEN PARADOKSU. EĞİTİM KURUMLARI ÜZERİNDE HERMENEUTİK FENOMOLOJİK BİR ÇALIŞMA
Authors: YARIM Mehmet Ali
Published: April 2023

Bu araştırmanın amacı okullardaki Abilen paradoksunu nedenleri ve sonuçları bağlamında incelemektir. Araştırma nitel araştırma desenlerinde biri olan fenomolojinin hermeneutik modelindedir. Araştırmanın çalışma grubunu amaçlı örnekleme yoluyla seçilen 2021-2022 eğitim öğretim yılında Erzurum il merkezindeki okullarda görev yapan 27 öğretmen oluşturmaktadır. Araştırmada veriler görüşme yöntemi ile elde edilmiştir. Elde edilen veriler içerik analizi yöntemiyle çözümlenmiştir. Araştırma sonuçlarına göre okullarda yüksek düzeyde Abilen paradoksu vardır. Öğretmenler özellikle yasal zorunluluklar, gruptan dışlanma korkusu ve sorumluluktan kaçma gibi nedenlerle istemedikleri veya inanmadıkları karar ve uygulamalara katılmak zorunda kalmaktadırlar. Okullarda öğretmenlerin iradesi ve inancı dışında alınan kararlar ve uygulamalar çoğu zaman başarısızlıkla sonuçlanmaktadır. Bu durumun verimsizlik, sinizm, zihinsel sıkıntı, motivasyon eksikliği, güvensizlik, olumsuz iklim ve başarısızlık gibi örgütleri ve okulları etkileyen sonuçları vardır. Bu sorunlara çözüm olarak çalışanların bilgilendirilmesi, kararlara katılması, özerklik verilmesi ve yönetişim kurallarının uygulanması önerilmektedir.
