The article is devoted to testing the capabilities of the “Types of Orientations in Difficult Situation” questionnaire (TODS; E. Bityutskaya, A. Korneev), as a tool for classifying perceived difficulties. The classification includes driven, maximal, optimal, ambivalent, and evasive types of perception of difficult life tasks. The first, second and third types correspond to approaching a difficulty, and the fifth type to avoiding it. The ambivalent type involves a combination of approach and avoidance. The study solves the following problems: to validate the correspondence of different variants of the TODS profile to the types, to compare the profiles with the marking of qualitative data (performed using content analysis), and identifying the capabilities of the questionnaire at different stages of classification. For this purpose, machine learning methods and A.S. Podkolzin's computer modeling of logical processes are used. The sample included 611 adult participants. The results of the study indicate the validation of the TODS questionnaire as a technique that makes it possible to divide perceived difficult life tasks into three large types: approach, ambivalent perception, and avoidance. The approach type includes three subtypes, two of which (involving the achievement of a high goal) are separated from the third, also on the basis of a questionnaire, with the addition of one marking feature. Thus, the questionnaire has been tested to solve new problems of psychodiagnostics, which allows using not only the indicators of separate scales, but the individual profile as a combination of scales.
Adaptation and Psychometric Analysis of the EmIn (D.V. Lyusin) Emotional Intelligence Questionnaire on an Azerbaijani Sample
Authors:   ANAS Philosophy and Sociology Institute, Baku, Azerbaijan, Ismayilova Nigar ,   Baku State University, Baku, Azerbaijan
Published: December 2024

The EmIn questionnaire assesses the main components of emotional intelligence, in particular, the ability to understand one's own emotions and the emotions of others, as well as the ability to manage these emotions effectively. The aim of the study was to evaluate the psychometric properties of this questionnaire and adapt it for an Azerbaijani population. The sample consisted of 390 participants, of whom 74% (289) were women and 26% (101) were men, aged 18-35 (M=19, SD=4.94). Using EFA, the two-factor structure of the questionnaire was determined: the two-factor solution accounted for 25% of the total variance, and the factor loadings revealed a range of values, while the lowest recorded value was .399, and the highest was .704. The study evaluated four models: a five-factor model, a two-factor model, a two-factor model obtained as a result of exploratory factor analysis, and a modified two-factor model. CFA results demonstrated a high degree of agreement with the modified two-factor model (CFI=0.913). The internal consistency of the EmIn questionnaire shows acceptable psychometric indicators and partially corresponded to the original version (interpersonal EI = .872, intrapersonal EI = .777, and general EI = .799). Significant gender differences in intrapersonal emotional intelligence were revealed: men showed significantly higher results than women. The Azerbaijani version of the EmIn questionnaire generally demonstrates satisfactory psychometric properties. Although the current study used fundamental methods of psychometric analysis to evaluate the results, it is important to recognize that it is not without limitations. One important aspect that requires further study is the validity analysis of the questionnaire.

Authors: Barrios Duniel , Sánchez Jorge A. , González-Torres Luis R.
Published: December 2024

Studies on the germination of Caribbean cacti are essential for conservation and ecological restoration programs. We evaluated the seed traits and germination response of Pilosocereus robinii under five temperatures and two light conditions and compared the vigor of the seedlings obtained. Seminal traits showed characteristics of orthodox seeds. Pilosocereus robinii seeds showed positive photoblastism and a range of optimal temperatures below 30°C. In all treatments where germination was suboptimal, the seeds demonstrated high recovery percentages when they were exposed to the optimal temperature. The vigor of the seedlings showed a behavior similar to germination. Our study shows that restoration plans for the species' populations are viable from seeds.

Authors: Garoche Clementine , Kubíčková Barbara , Blumburg Bruce , Jacobs Miriam , Balaguer Patrick
Published: December 2024

The HG5LN-hPPARγ assay using a reporter gene technique is an in vitrotool that provides mechanistic data. The assay is used to establish signalactivation (agonism) or blocking of the hPPARγ (antagonism) caused by a ligand.Unliganded chimeric PPARγ binds to GAL4RE and transactivates luciferase at abasal level. Once a chemical ligand binds to chimeric PPARγ, together they formheterodimers with RXR and recruit cofactors to modulate luciferasetranscription. The expression of luciferase is thus directly linked to theconcentration of the effector ligand. Once the substrate of luciferase,luciferin, is added to the cells, it is possible to assess transactivation bymeasuring cell luminescence. Luciferase activity can be evaluated quickly andinexpensively with a number of commercially available test kits. The testsystem for the assessment of the relative hPPARγ activation by test chemicalsprovided here utilises the HG5LN-hPPARγ cell line.

The contributions of this study are twofold: first, the development of a hybrid optimization technique that enhances routing efficiency in IoT networks, and second, the demonstration of its effectiveness through comparative analysis with conventional algorithms. ...
Enhancing Distribution System Flexibility through Network Restructuring and Optimal Planning of Distributed Energy Resources
Authors: Ma Rui , Zhao Yuhao , Li Jianfeng
Published: December 2024

This research introduces a novel outage management strategy (OMS) designed to enhance the resilience of distribution systems (DiSs) during severe weather-induced power outages. The approach incorporates an innovative network restructuring technique that utilizes an updated matrix to efficiently identify and reconfigure the radial network's topology following line faults. This restructuring optimizes the use of distributed energy resources (DERs) by strategically replacing connection and cross-section lines, formulated as an optimization problem solved through the social spider optimization algorithm. The key contributions include a unique matrix rank-based topology modeling method that avoids traditional empirical topological searches, proving effective in N-1, N-2, and N-3 scenarios. Comprehensive planning of DERs, encompassing both dispatchable and non-dispatchable resources, ensures optimal power supply during crises, even in systems with low to moderate DER penetration.
Design and Implementation of Human-Like Ambidextrous Robotic Arms for Cooperative Tasks
Authors: Hamouda A M. , Abdellatif E. M. , Al Akkad M. A.
Published: December 2024

In this paper an anthropomorphic robotic complex which consists of a robotic body with two robotic arms is designed for the purpose of achieving cooperative tasks. This research platform also aims to accelerate the creation and testing of control algorithms for humanlike anthropomorphic robots. An adaptive optimization algorithm based on differential evolution approach is proposed to solve the inverse kinematic problem. This algorithm facilitates finding a desirable solution easily and with less calculation cost compared to analytical and numerical methods, the thing that allows achieving realistic and efficient motion. This algorithm maintains balance between exploring new options and using current knowledge. Newton-Euler recursive approach is used for determining the robots dynamic properties. Then the required actuators are chosen, and stress analysis is conducted to evaluate the structural integrity of the robot and its capacity to withstand substantial loads. Adjustable backstepping fuzzy control method is used that is more robust to uncertainties, nonlinearities, and external disturbances and offers the robot the ability to perform movement in space, cooperate, and complete tasks in a coordinated manner. Ellipsoid intersection localizing method is used for collision avoidance. The selected methods excel at predicting the joints ’ movements required to attain desired poses with great accuracy and avoid collision. In a future paper, a study of the hands of this robot will be introduced. This work has the potential to be applied in tasks that are dangerous for humans, or in human-like tasks such as maintenance and manufacturing.
Managing the Mechatronic Systems Obsolescence Based on Monitoring of Resource Fault Tolerance
Authors: Sokolov B. V. , Mironov A. N. , Shestopalova O. L.
Published: December 2024

The article discusses the features of the manifestation of advanced obsolescence of electronic components of mechatronic systems in comparison with the physical aging of their electromechanical and mechanical modules. The relevance of managing the obsolescence of mechatronic systems has been revealed through early planning and implementation of measures to ensure that the product is ready for target use throughout its specified service life. It is proposed to implement obsolescence management by justifying the supply routes of replaceable components in conditions of obsolescence of products, accompanied by a decrease in the availability of spare parts due to their decommissioning. The main types of obsolescence of mechatronic systems are considered, including functional, technical and economic obsolescence and degradation of resource fault tolerance. The main results of the development of a mathematical model of degradation of the resource fault tolerance of a mechatronic system based on the analysis of obsolescence trees are presented. The apparatus of obsolescence trees provides an opportunity to model the causal relationships between the transition of a mechatronic system to a state of irreversible failure, failures of system elements and the probabilities of carrying out measures to manage the obsolescence of a mechatronic system in conditions of its obsolescence. During the development of the model, an integral equation of obsolescence of a mechatronic system with degradation of resource fault tolerance was obtained, an approximate method of solving it was proposed, as a result of which point and interval estimates of forecasts of the values of the gamma percent service life of a mechatronic system before the onset of obsolescence were obtained. Expressions are obtained to determine the preferred ways to compensate for the obsolescence of a mechatronic system with degradation of resource fault tolerance according to the criterion of maximum technical and economic efficiency. An algorithm for choosing the preferred method of managing obsolescence of a mechatronic system in terms of technical and economic efficiency is presented.

Authors: Velichkova L.V. , Yanchich N.A.
Published: December 2024

The article presents the results of a study aimed at determining the degree of influence of speech rate on the listener's differentiation of the speaker's speech type based on the productivity/reproductivity feature. This topic is especially relevant in connection with the development of modern technologies for perceiving human speech and generating artificial speech. We are at the point in the development of these technologies when machine-generated speech is still easily recognized by the listener as artificial, although the similarity to productive human speech remains great. This allows us to put forward a hypothesis that there are speech parameters that allow the listener to perceive it as productive, reproductive, or artificial. In this article, we present the results of the first part of the study, which touched upon the search for differentiating parameters for productive and reproductive speech. The study was conducted on the materials of audio recordings of productive and reproductive speech of two male speakers with different behavioral characteristics, including those expressed in speech. The dependence of the speech productivity feature on the speech rate was established. A concomitant dependence of the speech rate on the emotional state and intention of the speaker was revealed. A description of the results obtained in determining the differences between the rate and speed of the speaker's speech is given.

Authors:   The Korean Logistics Research Association, Moscoso, Esteban Moscoso, Esteban , Park Hong-Gyue
Published: December 2024

This study conducted a relative efficiency analysis using DEA on 20 warehousing and storage companies as of 2023. The analysis revealed that companies classified in the general warehousing sector operated more efficiently than those targeting niche markets like hazardous materials or cold chain logistics. Additionally, the Malmquist Productivity Analysis showed that external factors, including technological change, contributed more to overall productivity growth from 2021 to 2023 than changes in internal efficiency. This highlights the importance of companies adopting technology and responding quickly to external factors such as deregulation and market structure changes. The study diagnoses the current situation of logistics warehouse companies in 2023, amid oversupply in the logistics center and real estate market and the slowdown of the e-commerce market. The key finding of this study is that large-scale general warehousing companies tend to perform better in the market, but what brought the productivity changes are mainly due to technological adoption and application which can also be the driving force of growth for other warehousing companies. The equilibrium of warehousing facilities are going to be changed due to the market structure changes, but what remains as the most important factor for success is combining internal efficiency and more importantly, external factors that can shift the efficiency level to a new height.
Efficiency Analysis of Shipping, Aviation, Land Transport, and Railway Industries Using DEA-Malmquist : Focusing on Supply Chain Risks
Authors:   The Korean Logistics Research Association, Kim Cho-Yeon , Kim Soo-Hyo
Published: December 2024

This study conducts a DEA-CCR/BCC and DEA-Malmquist analysis on the primary logistics networks of the maritime, aviation, land transportation, and rail industries over the past decade. The research aims to evaluate the impact of global supply chain risks, such as the COVID-19 pandemic, the U.S.-China trade war, the Russia-Ukraine war, and the Suez Canal blockage, on the efficiency of the logistics industry. In a context where the importance of supply chain stability is increasing, the study seeks to identify changes in efficiency across industries and propose strategies for improvement.
The analysis shows that the overall efficiency of the domestic logistics industry has improved; however, volatility increased significantly during the COVID-19 pandemic period (2019-2021) across all sectors. In particular, the maritime and aviation industries, which are highly influenced by the global economy, experienced a decline in the Malmquist Productivity Index (MPI) due to events such as Brexit (2016-2017), the U.S.-China trade war (2017-2018), the Suez Canal blockage (2021), and the Russia-Ukraine war (2022). In contrast, the land transportation and rail industries, which focus on the domestic market, showed relatively lower volatility.
These findings highlight the need to identify external risks and develop strategies to enhance the competitiveness of the domestic logistics industry. Moreover, adopting digital transformation and automation can maximize technical efficiency, while building environmentally friendly logistics systems is essential for sustainable development. Tailored strategies for each industry are crucial to mitigate risks across both domestic and international markets. Additionally, modernizing logistics infrastructure will be a key priority moving forward.

Published: December 2024

In today’s highly competitive global market, a company’s success often hinges on how well it can identify and build productive partnerships. This is especially true in supply chain management, where the relationship between suppliers and buyers plays a huge role in determining how efficiently a business runs and how profitable it can be. Traditionally, companies have relied on long-established networks and past relationships when selecting partners. However, this approach can be limiting, as it often overlooks new opportunities due to gaps in information or preconceived biases. To tackle this challenge, the authors of the study introduced a new model based on Deep Neural Networks (DNN). This model is designed to help businesses in South Korea identify potential partnerships across a variety of industries. By taking factors like company size, product offerings, and market position into account, the DNN model can pinpoint partnerships that would be mutually beneficial. The results were striking—there was a significant increase in the number of potential partnerships identified, showing just how effective this approach could be in widening the scope of business collaborations. Notably, the model identified numerous feasible buyer companies that had not been previously considered by suppliers, suggesting that DNN-based recommendations can challenge and reshape traditional perspectives on business compatibility. This research contributes to the growing body of AI-driven business processes and offers practical insights for companies seeking to enhance their supply chain networks through the adoption of innovative technological solutions.

Examining the Meaning of Conceptual Learning as a Learning Experiences
Authors:   The Korea Association of Yeolin Education, Park Young-Ju , Kim Bitna
Published: December 2024

The 2015 and 2022 revised curriculum, which aims to develop learners’ competencies, promotes deep understanding through ‘Core concepts’, ‘Generalized knowledge’, and ‘Key ideas’. However, there is a gap between research and practice in the field of education. In this study, we examined the characteristics of concepts, what it means to understand concepts, and what it means to use concepts and practical understanding of concepts in the learning process from the perspective of embodied cognition, focusing on learning experience and interactions. The followings are the findings of the study. Firstly, understanding a concept is a process in which learners go beyond memorizing or acquiring the meaning of a concept to contextualize and reconstruct it by integrating it into their lives and experiences. Secondly, conceptual understanding in the learning process is a process of continuous adjustment to flexibly adapt to different situations. This exploration and adjustment based on learning experience is facilitated by active, engaged, and collaborative interactions within the learning environment. Finally, utilizing concepts refers to the process of learning transfer, where learners adapt and respond to the world in appropriate ways, adapting their understanding of concepts to fit the situation. In this way, learners are able to experience complex phenomena and the world in a more integrated and concrete way.

Authors: Hernández-Salazar Cristian A. , Carreño-Verdugo Alejandro , González-Estrada Octavio Andrés
Published: December 2024

This paper presents the development of a Long Short-Term Memory neural network designed to predict the volume fraction of liquid-liquid two-phase flows flowing through horizontal pipes. For this purpose, a comprehensive database was compiled using information sourced from existing research, comprising 2156 experimental data points utilized for model construction. The input of the algorithm consists of a vector containing the superficial velocities of the substances (oil and water), the mixture velocity, internal pipe diameter, and oil viscosity, while the output is the volume fraction of oil. Training and validation procedures involved preparing and segmenting the data, using 80% of the total information for training and the remaining 20% for validation. Model selection, based on performance evaluation, was conducted through 216 experiments. The predictive model with the best performance had a Mean Squared Error (MSE) of 3.5651E-05, a Mean Absolute Error (MAE) of 0.0045, and a Mean Absolute Percentage Error (MAPE) of 3.0250%. This performance was obtained by structuring the model with a ReLu transfer function, 20 epochs, a learning rate of 0.1, a sigmoid transfer function, a batch size of 1, ADAM optimizer, and 150 neurons in the hidden layer.

Los estudios del flujo en estructuras de control requieren desarrollar ecuaciones diferenciales no lineales que no tienen solución analítica pero que se pueden aproximar a partir de la aplicación del método de volúmenes finitos en los modelos matemáticos como lo es Fluent. El artículo presenta un análisis comparativo entre un modelo numérico y un modelo físico del flujo de agua en un canal de laboratorio utilizando ANSYS Fluent. El alcance del estudio abarca desde el desarrollo de un modelo 2D del canal de laboratorio con sección de control de tipo compuerta rectangular plana deslizante y el desarrollo matemático de las ecuaciones de Navier-Stokes para modelar un flujo bifásico de agua y aire en todo el dominio computacional, utilizando las condiciones de contorno adecuadas. Para la metodología se empleó técnicas de simulación numéricas utilizando ANSYS Fluent, aplicando el método de volúmenes finitos para resolver las ecuaciones de flujo y técnicas experimentales, mediante mediciones directas tomadas en el laboratorio. Los resultados demuestran una similitud del 95.46% entre la modelación matemática, las mediciones directas y los cálculos analíticos. Mientras que las variables como el coeficiente de descarga, los perfiles de flujo, las velocidades en diferentes puntos del canal y la distribución de la presión se mantuvieron consistentes en todo el dominio computacional. En conclusión, se destacan las ventajas del modelo numérico sobre el físico, resaltando su eficiencia y economía al permitir modificaciones en las configuraciones del problema, así como en los modelos de turbulencia y condiciones de contorno de manera fácil y simultánea. Además, se resalta la importancia del modelo numérico al proporcionar resultados más precisos que las mediciones directas hechas en el modelo físico, especialmente en las zonas de turbulencia y en la interacción del flujo bifásico en el canal y en la compuerta. Finalmente, es importante incluir en este tipo de estudios un análisis de sensibilidad y refinamiento del mallado en el modelo matemático para evitar fluctuaciones cerca de la compuerta donde la sección se contrae.

El objetivo de la investigación es evaluar una contramedida para la reducción de la socavación local en muros longitudinales en ríos con lecho granular bien gradado empleando el software Flow-3D, se selecciona la contramedida empleando el método multicriterio Analytic Hierarchy Process (AHP) y se modela numéricamente con pendientes de 2.5% y caudal de 1.68 m3/s. Mediante el método AHP se obtiene que la alternativa con mayor jerarquía son los mini-espigones, por lo cual se modelan escenarios de 0.3, 0.45 y 0.6 m de dimensión dispuestos en dirección y en contraflujo. La simulación en el software demostró que la contramedida de mini-espigones de 0.45 m de longitud dispuestos en contraflujo, presentaron una eficacia del 75 %, en comparación con los de 0.3 m y 0.6 m cuyas eficacias son 60.69 % y 51.12 % respectivamente. La investigación es un aporte significativo al planteamiento de alternativas de protección muros longitudinales.
Dynamics of interacting SIRS+V models of infectious disease spread
Authors:   Saratov State University, Russia, Shabunin Aleksej
Published: December 2024

The purpose of this work is study of processes of spread of infectious diseases in metapopulations interacted through spontaneous migration.

The method is based on theoretical examination of the structure of the phase space of a system of coupled ODEs and numerical study of the transient processes in dependence on the coupling between subsystems.

Results. A model of interacting populations in the form of two identical SIRS+V systems with mutual diffusion coupling is proposed and investigated. It was found that the long-term dynamics of the metapopulation does not differ from the behavior of an individual population; however, its transitional dynamics may be different and significantly depends on the values of the migration coefficients of infected and healthy individuals. In particular, under certain conditions, a complete suppression of infection waves can be observed in a secondarily infected population.

Discussion. Despite the extreme simplicity of the model and the observed regimes, the results may be interesting from the point of view of practical recommendations for planning a strategy to combat transmission between communities, since they reveal the influence of the intensity of migrations of sick and healthy individuals on the spread of the epidemic in metapopulations.
Acute Pancreatitis after Lumbar Spine Surgery: A Case Report

Published: December 2024

Acute pancreatitis is a rare but potentially life-threatening complication that typically occurs after various abdominal procedures, but it is extremely uncommon following spinal surgery. This case study describes a 38-year-old male martial arts champion who developed acute pancreatitis after undergoing lumbar laminectomy and Transforaminal Lumbar Interbody Fusion (TLIF) surgery for chronic lower back pain and bilateral radiculopathy in both legs. Despite the absence of typical risk factors, such as alcohol consumption or a history of pancreatitis, the patient developed abdominal pain, nausea, and vomiting on the second postoperative day, along with elevated serum amylase levels. These clinical findings raised suspicion for acute pancreatitis, which was subsequently confirmed through diagnostic imaging. Prompt treatment led to the resolution of symptoms and normalization of pancreatic enzyme levels. This case underscores the importance of recognizing and managing uncommon complications following spinal surgery, highlighting the necessity for a comprehensive, multidisciplinary approach to ensure optimal patient care.
Teología de la ciudad. La pastoral en la ciudad como una acción política
Authors: Mayor Tamayo Jhon Fredy
Published: December 2024

Puede la teología decir algo sobre la ciudad, ¿en especial cuando el crecimiento de la ciudad parece no tener fin y los múltiples problemas que esta afronta ponen en riesgo su permanencia en el futuro? Ante los desafíos que enfrenta la ciudad del siglo xxi, han surgido propuestas que ven en la tecnología una alternativa para resolver sus múltiples problemas, con el objetivo de transformarla en el espacio ideal que los “hombres han deseado”. Ante esa necesidad apremiante de salvar la ciudad, la teología (el teólogo) ha de sumarse a esa causa colectiva, contribuyendo a este proyecto salvífico, el cual no es ajeno a la tradición cristiana (cfr. Ap 21, 3). En la manera como se conciba la ciudad (escatológica) y se ejerza la pastoral en la ciudad (acción política) está el aporte de la teología y la Iglesia.
El rostro martirial de la Iglesia salvadoreña desde las biografías teológicas de Óscar Romero e Ignacio Ellacuría. Una revalorización de la dimensión profética en el ministerio ordenado
Authors: Mauti Ricardo Miguel
Published: December 2024

El presente artículo desarrolla a modo de investigación lo que en el origen fue una ponencia presentada en las Jornadas LEST en la Universidad de Lovaina en noviembre de 2023. El tema aborda la dimensión martirial de la Iglesia salvadoreña desde las biografías de dos exponentes: Óscar Romero e Ignacio Ellacuría. El método utilizado es el de la teología biográfica, la cual implica lecturas contextuales de las figuras analizadas, recurso a las fuentes documentales de los personajes y la confrontación con la teología de la liberación en lo que ha aportado fundamentalmente en temas como liberación y martirio. Nuestra contribución busca revalorizar para el ministerio ordenado la dimensión profética, que, según el consenso de varios especialistas, ha quedado marginada en la teología del sacramento del orden por una alteración indebida del tria munera querido y recomendado por el Vaticano II y su mejor recepción en América Latina. En primer lugar, planteo el contexto geopolítico/eclesial salvadoreño entre 1977 y 1989. Analizo luego los vínculos que existen entre liberación y martirio. En tercer lugar, muestro cómo los mártires salvadoreños interpelan al ministerio ordenado. En cuarto lugar, señalo algunas dificultades de la Iglesia universal en la recepción de los mártires de la justicia. Finalizo con algunas conclusiones abiertas que puedan dar pie a ulteriores investigaciones.
Hakir ile Fakir, Ben ile Biz: Osmanlı-Türk Toplumunda Kendini Anlatmanın Dayanılmaz Hafifliği

İstanbul Medeniyet Üniversitesi’nde 2020 ve 2022’de yapılan etkinliklerin bir meyvesi olan bu özel sayıda, benim önsöz ve giriş yazılarım dışında 15 makale bulunmaktadır. Makalelerin 6’sı 2020’de sunuldu, diğer 6’sı ise 2022’de. Üç makale (Aliyev, Çörekçi, Tuncer) etkinliklerimizde sunulmadı; ancak bu derlemeye alınması uygun görüldü. Derlemedeki makalelerin 11’i Türkçe, 4’ü İngilizce olarak kaleme alındı. Makalelerin dillerine müdahale edilmedi, yani dergi Türkiye’de çıkıyor diye İngilizce metinlerin Türkçeye tercümesi düşünülmedi. Osmanlı Araştırmaları Dergisi’nin uluslararası profili ve geçmiş sayılarındaki örüntü buna uygundur. Bunun yerine, iki dilli yayının doğasına uygun olarak, Türkçe okuyamayan meslektaşlarımızın da bu seçkiden maksimum istifadesi için kendi yazdığım başlangıç yazılarını çift dilli kaleme aldım.
