Phenomenological Study on the Client Experiences of Elder Counseling Specialists
Authors:   Korean Society of Educational Gerontology, Lee Hosun
Published: December 2024

As we enter an era with a population of ten million elderly, the difficulties and issues faced by the elderly are also increasing. However, there is a significant shortage of personnel and experiential resources to provide counseling services specifically for the elderly. It is necessary to explore and expand our understanding of elder counseling through the experiences of those working as elder counseling specialists. For this study, six counselors with a master's degree or higher, over five years of clinical experience, and more than 500 cases of elder counseling—who have also counseled non-elderly clients for at least five years—were selected. In-depth interviews were conducted both face-to-face and remotely to explore the unique characteristics, counseling processes, and evaluations in elder counseling. The data were analyzed phenomenologically using Colaizzi's method, resulting in 20 meaning units and five sub-components, which were integrated into two main components. The components identified were transference-countertransference in elder counseling and the impact of elderly clients' understanding and personality traits on counseling. The sub-components included strong transference by elder counselors, the barrier of countertransference, limits of elderly clients' willingness for counseling, differences in understanding of counseling among elderly clients, and counseling outcomes based on the characteristics of elderly clients. This study aims to be used as foundational data for establishing a Korean elder counseling model by concretizing the characteristics experienced by elder counseling specialists during their practice.
The Comparison of Issues in Academic Journals and News Articles on Elderly Learners: A Keyword Network Analysis
Authors:   Korean Society of Educational Gerontology, Lee Younjin
Published: December 2024

This study aimed to analyze how the academic discourse on elderly learners aligns or differs from the social demands observed in practical areas, with the goal of strengthening the connection between these two domains. To this end, a keyword network analysis was conducted to identify the keywords and themes related to elderly learners in domestic academic journals and news articles. The results revealed that academic journals focused on core keywords such as ‘life’ and ‘cultural arts’, emphasizing the quality of life, psychological well-being, and physical health of elderly learners. In contrast, news articles highlighted keywords like ‘employment’ and ‘transportation’, emphasizing the economic situation of the elderly and their characteristics as a vulnerable group. These findings suggest that academic research should work to identify topics that make practical contributions to the lives of elderly learners by better integrating with real-world issues. Based on the findings of this study, the need for an integrated approach between research and practice is emphasized for the development of customized lifelong education programs for elderly learners. The study also suggests directions for policy support and program design that meet the diverse educational needs of elderly learners.

Authors:   Korean Society of Educational Gerontology, Lee Romee , Lee Eun ju
Published: December 2024

This study aims to systematically analyze the current major research trends of academic discourse on death education in Japan in the context of a super-aged society, and to draw research and practical implications for death education in Korean society. Using systematic review as a research method, a total of 220 academic papers were selected in order of top ranking from Google Scholar and CiNii, as two representative academic databases in Japan, under death education(English) (n=50), death education(Japanese) (n=67), death and life studies (n=95), and life education (n=8). As a result of the research, death education in Japan has been evolving since the 1990s based on ethical approaches and academic practices, and interdisciplinary research has been carried out as being centered on both school and community education. The main content has evolved into the development of various practice programs reflecting the philosophy of life and death and the entire life cycle. Based on these results, this study discusses the directions, tasks, and practical measures of death education that can be applied to Korean society as well as to researchers and workers who work with elderly citizens. Since Korea is entering a super-aged society where a continuous increase in so-called deaths of despair accompanies, more efforts are urgently needed in this area.

Imagining Democratic Futures: Southern Africa Foresight Report 2025
Authors:   International Institute for Democracy and Electoral Assistance (International IDEA)
Published: December 2024

Data from International IDEA’s Global State of Democracy Indices show that Southern Africa has consistently been Africa’s highest performing subregion in many areas of democracy but recent trends appear to contain the seeds of a much less certain future. Economic inequality remains high, governments are struggling to deliver basic goods and services, and citizen satisfaction with democracy is declining. These are volatile times. If we wish to adequately prepare democracies in Southern Africa for what is to come, we must go beyond extrapolating from these trends. Stakeholders must anticipate and position themselves for a variety of possible long-term futures. How might these futures look?
International IDEA and the Institute for Security Studies convened a multidisciplinary group of experts and practitioners from across Southern Africa for a foresight conference to identify and explore future democratic challenges and opportunities in the subregion. This Discussion Paper presents the outcomes of that conference.

The crisis at the Mexican-American border and the migration policy externalization practices
Authors: Kudeyarova N. Yu
Published: December 2024

The article treats the crisis situation on the Mexican-American border. The migration flow new characteristics analysis shows that two sources of migration tension in the Western Hemisphere – the Venezuelan and Central American crises - are partly united. The migration policy externalization pursued by the US in Mexico as well as other countries of the region has become an important element of the flow containment strategy. In turn, Mexico is beginning to take steps to implement development programs in some migrant origin countries. While the US and Mexico’ actions are forced to synchronize by the current crisis situation, each country focuses on its own strategy to reduce tension on the shared border.
Structural-Semantic Analysis of Verbs and Nouns Representing Bird Vocalizations in M. Prishvin’s Artistic and Diary Heritage
Authors: Abreimova Galina N. , Borodina Nadezhda A. , Burtsev Vladimir A.
Published: December 2024

This article investigates the linguistic means employed to convey avian vocal signals within M. Prishvin’s writer’s perspective. The study used the AntConc software and was conducted in two stages, resulting in the formation of the writer’s ornitophonosphere depiction as a complex, multi-level phenomenon. Initially, all ornithonyms encountered in M. Prishvin’s literary works and diary entries were identified, followed by an analysis of their most vivid verb-based and noun-based sound-descriptive lexemes. Authors adhere to traditional classification in describing bird sounds, enabling the differentiation of vocal diversity among avian species in M. Prishvin’s oeuvre based on loudness, intensity, pitch, timbre, tempo, and clarity. The application of corpus analysis of the collected data helped to create a comprehensive picture reflecting the multi-layered and individual ornithophonosphere of the writer, demonstrating his deep understanding and sensitive perception of the surrounding world. The analysis of lexical richness and linguistic finesse of M. Prishvin’s idiolect in capturing avian vocalizations not only reveals the writer’s unique approach to ornithological themes but also provides the readers with a deeper understanding of the true voice of nature through the prism of his artistic and diary heritage.

Radio-Frequency Electromagnetic Background Created by Mobile (Cellular) Communications
Authors: Mordachev V. I.
Published: December 2024

The technique of integral assessment of the radio frequency electromagnetic background (EMB) intensity created by wireless information services is presented, based on the forecast of the average electromagnetic loading on area created by radiations of spatially distributed base stations and mobile terminal devices. This loading can be determined both on the basis of a direct estimate of the average total irradiation power of the Earth’s surface by base stations or the average total radiation power of terminal devices per unit of its area, and on the basis of an estimate of the average area traffic capacity and known parameters of equipment and topology of mobile communication networks. Expressions to estimate the conditional average levels of EMB generated by stationary and mobile components of mobile communication systems, and the results of calculations illustrating the processes of its generation by these systems in different frequency ranges with different average area traffic capacity and different sizes of service areas of base stations are given. These calculations confirm the real danger of an unacceptable decrease in the level of electromagnetic safety of the population and deterioration of the ecology of the habitat without the implementation of scientifically based restrictions on the characteristics of mobile communication systems and services.

Published: December 2024

A numerical modeling of the process of a high-speed impact of a massive asteroid with the Earth’s surface was carried out to study the hypothesis of the meteoritic origin of the impact diamond deposit located in the Popigai River basin. A normal collision of a chondritic asteroid with a layered structure of the Earth’s soil at a speed of 25 km/s is simulated in 2D axisymmetric formulation. The natural carbon deposit layer is located in the near-surface zone of the loaded area. The calculations were carried out using a multidimensional parallel implementation of the finite-size particle-in-cell method. Models of the equations of state of chondrite, quartz and carbon are used to describe the properties of the meteorite and soil material. Thermodynamic parameters of impact compression of soil materials at the initial stages of loading and crater formation processes are obtained.

Authors: Petrov Yu. V. , Selyutina N. S. , Antonova M. N.
Published: December 2024

The paper studies the multi-stage fatigue dependence (Wöhler diagram) of the material and proposes a new model for its prediction based on considering the mechanisms of plastic deformation and fracture under cyclic loads and a combination of relaxation processes with the evolutionary development of damage, for which the initial condition is formed using the calculation calculated during the cycling process energy of irreversible deformation. The performance of the model is verified using the results of cyclic deformation tests on DP500 steel as an example. It is shown that within the framework of a unified approach it is possible to simultaneously evaluate the short-term, fatigue and long-term strength of the material.

Published: December 2024

Mathematical modeling and investigation of the filtration process of salt water in the sedimentary column, taking into account the phenomenon of osmosis, has been performed. It is shown that the osmotic interaction of salt and fresh water in a sedimentary column containing interlayers and inclusions of poorly permeable rocks (clays, silts, etc.) can lead to the appearance of zones of large pressure anomalies and the destruction of the geomedium. The proposed osmotic mechanism of destruction of the geomedium explains the formation of pockmarks and craters on the surface of passive areas of the crust that do not experience any movements and deformations for a long period of time. This mechanism is an alternative to the common point of view about a polygonal fault system of tectonic nature, on the basis of which marks on the seabed or craters in permafrost areas on land are explained. The mathematical model under study showed that under the conditions under consideration, convection of a solution with closed current lines occurs, similar to gravitational convection.

Published: December 2024

Traffic jams have become a serious problem in many countries, including Indonesia. Traffic management is a challenging task, especially in developing countries. One of the causes of traffic jams is long lines of vehicles at intersections because the traffic light signals are on at the same time without paying attention to the number of vehicles queuing. The computer vision approach can be applied as a solution by minimizing waiting time for drivers by adjusting the length of time the green light signal is on based on the number of vehicles in each lane. To carry out this approach, a vehicle detection system was built using the YOLOv8 (You Only Look Once 8th version) algorithm, which operates in real-time. The data used comes from CCTV installed at every traffic light at intersection four. The YOLOv8 algorithm shows high accuracy and efficiency in object detection in various studies. To find out to what extent the YOLO model that has been built can predict the data correctly, it is necessary to evaluate the model by calculating accuracy, recall and mAP50 score. This research aims to build an intelligent traffic light management system using YOLOv8, based on computer vision and the OpenCV library. The results obtained from this system calculation are an accuracy value of 0.689, a recall value of 0.578, and an mAP50 score of 0.65.

Published: December 2024

Quadrotors are intrinsically unstable. If there is a sudden wind disturbance, this wind disturbance will be amplified so that the quadrotor's attitude becomes uncontrollable. West Java is one of the regions in Indonesia that has quite high wind disturbances. The recorded daily wind disturbance reached 6.99 m/s with a maximum value of 9.95 m/s. In this research, a control system based on the sliding mode control (SMC) algorithm is used. The advantage of this control algorithm is its ability to compensate for uncertain disturbances. This research investigates the implementation of the SMC control into a quadrotor by incorporating random wind disturbance aspects into the model. The research was carried out numerically with simulations using MATLAB/Simulink, with the position variables being the main focus. Quadrotor equipped with SMC has a lower mean error value for the desired position relative to the real position. This shows that the SMC control algorithm that has been created is able to properly overcome random wind disturbances that occur in the West Java area.

Leveraging LLM for Identification and Extraction of Normative Statements
Authors: Zin May Myo , Satoh Ken , Borges Georg
Published: December 2024

The development of autonomous vehicles (AVs) requires a comprehensive understanding of both explicit and implicit traffic rules to ensure legal compliance and safety. While explicit traffic laws are well-defined in statutes and regulations, implicit rules derived from judicial interpretations and case law are more nuanced and challenging to extract. This research investigates the potential of Large Language Models (LLMs), particularly GPT-4o, in automating the extraction of implicit traffic rules from judicial decisions. By utilizing various prompt engineering techniques, including Standard Prompts, Chain-of-Thought (CoT), Chain-of-Instructions (CoI), and Layer-of-Thought (LoT) prompts, this study aims to assess the effectiveness of GPT-4o in identifying normative content relevant to specific traffic laws. The contributions of this paper include an assessment of LLMs for legal text processing, the automation of implicit rule extraction, and the development of a scalable framework that can continuously update as new legal precedents emerge. The results indicate promising avenues for integrating automated normative extraction in AV systems, improving both the safety and legal compliance of autonomous driving technologies.
Conflict Analysis for Timed Contract Automata
Authors: Azzopardi Shaun , Pace Gordon J.
Published: December 2024

One can find various temporal deontic logics in literature, most focusing on discrete time. The literature on real-time constraints and deontic norms is much sparser. Thus, many analysis techniques which have been developed for deontic logics have not been considered for continuous time. In this paper we focus on the notion of conflict analysis which has been extensively studied for discrete time deontic logics. We present a sound, but not complete algorithm for detecting conflicts in timed contract automata and prove the correctness of the algorithm, illustrating the analysis on a case study.

Neural operators for hydrodynamic modeling of underground gas storage facilities
Authors: Sirota D. D. , Gushchin K. A. , Khan S. A. , Kostikov S. L. , Butov K. A.
Published: December 2024

Objectives. Much of the research in deep learning has focused on studying mappings between finite-dimensional spaces. While hydrodynamic processes of gas filtration in underground storage facilities can be described by partial differential equations (PDE), the requirement to study the mappings between functional spaces of infinite dimension distinguishes this problem from those solved using traditional mapping approaches. One of the most promising approaches involves the construction of neural operators, i.e., a generalization of neural networks to approximate mappings between functional spaces. The purpose of the work is to develop a neural operator to speed up calculations involved in hydrodynamic modeling of underground gas storages (UGS) to an acceptable degree of accuracy.

Methods. In this work, a modified Fourier neural operator was built and trained for hydrodynamic modeling of gas filtration processes in underground gas storages.

Results. The described method is shown to be capable of successful application to problems of three-dimensional gas filtration in a Cartesian coordinate system at objects with many wells. Despite the use of the fast Fourier transform algorithm in the architecture, the developed model is also effective for modeling objects having a nonuniform grid and complex geometry. As demonstrated not only on the test set, but also on artificially generated scenarios with significant changes made to the structure of the modeled object, the neural operator does not require a large training dataset size to achieve high accuracy of approximation of PDE solutions. A trained neural operator can simulate a given scenario in a fraction of a second, which is at least 106 times faster than a traditional numerical simulator.

Conclusions. The constructed and trained neural operator demonstrated efficient hydrodynamic modeling of underground gas storages. The resulting algorithm reproduces adequate solutions even in the case of significant changes in the modeled object that had not occurred during the training process. The model can be recommended for use in planning and decision-making purposes regarding various aspects of UGS operation, such as optimal control of gas wells, pressure control, and management of gas reserves.

Objectives. To develop analytical approaches for the evaluation of probability-time characteristics and fiber distributed data interface (FDDI) network performance with the marker access method, thus enabling communication processes for digital electrical substations to be automated.

Methods. The authors used theory reliability methods, random process theory, mass maintenance theory, the Laplace–Stieltjes transformation for inferring functional equations and the probability-time characteristics calculation for the information transfer processes with the occurring failures.

Results. We conducted a numerical study of packet transfer processes between central processing stations in the FDDI network. We considered the processes of discrete information exchange between electronic devices in the system of electrical digital substations. These included the main technological operations and electrical digital substations operator performed when preparing reports. We described the different modes of operation, both for the individual electrical digital substation and for the system. The authors calculated node loading dependencies, FDDI network performance and temporal characteristics of the packet transfer processes on the incoming message flow intensity and the transmission medium reliability. We conducted a functional analysis of the FDDI networks on two fiber-optic rings which form the main and redundant path of data transfer between the network nodes, significantly increasing network resiliency. The objective of the study was to analyze the information transfer processes in FDDI networks with an accent on ensuring the transmission medium reliability.

Conclusions. We were able to establish the existence of the critical operating network region, which leads to a sharp increase in node load and temporal characteristics, while performance reaches its maximum value and then sharply decreases. We propose the exchange of discrete messages to reflect the electronic devices state and information messages of operator between various remotely spaced electrical digital substation with the FDDI fiber-optic network.
Reflections of linearly polarized electromagnetic waves from a multilayer periodic mirror
Authors: Nurligareev D. Kh. , Nedospasov I. A. , Kharitonova K. Yu.
Published: December 2024

Objectives. The purpose of the article is to carry out a theoretical and experimental study of the angular reflection spectrum of linearly polarized electromagnetic waves from a multilayer periodic mirror on a transparent substrate to exact analytical expressions for reflection and transmission coefficients generalizing the cases of incidence of plane transverse electric (TE) and transverse magnetic (TM) modes on limited periodically structured media with a stepped refractive index profile.

Methods. The theoretical analysis of the reflection problem is based on the search for exact analytical solutions in the form of Floquet–Bloch waves presented in the form of inhomogeneous waves in the domain of periodically structured media. On the basis of the possible existence of a single Floquet–Bloch wave in a limited onedimensional photonic crystal, it is proposed to search for exact solutions of the wave equation in the form of a linear combination of inhomogeneous waves propagating in different directions. By using the canonical forms of the considered periodic structures, it is possible to carry out the simple transition from the case of TE polarization to TM type in dispersion relations and expressions for the angular reflection spectrum.

Results. Cases of reflection of linearly polarized radiation are considered for the following cases: a flat boundary of two dielectrics, a thin plane-parallel plate, and a multilayer dielectric mirror. Exact analytical expressions for the reflection and transmission coefficients generalizing the cases of incidence of TE and TM polarizations waves on a limited one-dimensional photonic crystal are obtained. The transmission coefficients of a plane TE wave from a multilayer dielectric mirror sputtered on thin glass were experimentally measured.

Conclusions. A quantitative and qualitative agreement of experimental measurements of the transmission coefficient of a plane wave incident from a half-space on a confined photonic crystal with theoretical calculations is obtained. The obtained expressions for the transmission coefficient of a confined one-dimensional photonic crystal, which are shown to be determined by the interference of Floquet–Bloch waves presented in the form of inhomogeneous waves, can be reduced to a form analogous to the expression for the value of the transmission coefficient of a traditional Fabry–Pérot interferometer. In the case of TM polarization, when the Brewster condition is fulfilled at the interlayer boundaries, the Floquet–Bloch wave has the form of homogeneous plane waves in the layers of a photonic crystal.
Development of model representations of thermal reaction viscoelastic bodies on the temperature field
Authors: Kartashov E. M.
Published: December 2024

Objectives. In recent decades, the relevance of research into the thermal response of solids to a temperature field has increased in connection with the creation of powerful energy emitters and their use in technological operations. There is a significant number of publications describing these processes using mathematical models of dynamic or quasi-static thermoelasticity, mainly for most technically important materials that obey Hooke’s law. However, at elevated temperatures and higher stress levels, the concept of an elastic body becomes insufficient: almost all materials exhibit more or less clearly the phenomenon of viscous flow. The real body begins to exhibit elastic and viscous properties and becomes viscoelastic. A rather complex problem arises: the development of dynamic (quasistatic) thermoviscoelasticity within the framework of the corresponding mathematical models of classical applied thermomechanics and mathematics. The purpose of the work is to consider the open problem of the theory of thermal shock in terms of a generalized model of thermoviscoelasticity under the conditions of classical Fourier phenomenology on the propagation of heat in solids. Three types of intense heating are considered: temperature, thermal, and medium heating. Intensive cooling modes can be equally considered. The task is posed: to develop model representations of dynamic (quasi-static) thermoviscoelasticity that allow accurate analytical solutions of the corresponding boundary value problems on their basis. This direction is practically absent in the scientific literature.

Methods. Methods and theorems of operational calculus were used.

Results. Model representations of the thermal response of viscoelastic bodies using the proposed new compatibility equation in displacements have been developed.

Conclusions. New integro-differential relations are proposed based on linear rheological models for the Maxwell medium and the Kelvin medium, including both dynamic and quasi-static models for viscoelastic and elastic media, generalizing the results of previous studies. The proposed constitutive relations of the new form are applicable to describe the thermal response of quasi-elastic bodies of a canonical shape simultaneously in three coordinate systems with a system-defining parameter, which makes it possible to identify the influence of the topology of the region on the value of the corresponding temperature stresses.
Grounding-IQA: Multimodal Language Grounding Model for Image Quality Assessment
Authors: Chen Zheng , Zhang Yulun
Published: December 2024

The development of multimodal large language models (MLLMs) enables the evaluation of image quality through natural language descriptions. This advancement allows for more detailed assessments. However, these MLLM-based IQA methods primarily rely on general contextual descriptions, sometimes limiting fine-grained quality assessment. To address this limitation, we introduce a new image quality assessment (IQA) task paradigm, GROUNDING-IQA. This paradigm integrates multimodal referring and grounding with IQA to realize more fine-grained quality perception. Specifically, grounding-IQA comprises two subtasks: grounding-IQA-description (GIQA-DES) and visual question answering (GIQA-VQA). GIQA-DES involves detailed descriptions with precise locations (_e.g._, bounding boxes), while GIQA-VQA focuses on quality QA for local regions. To realize grounding-IQA, we construct a corresponding dataset, GIQA-160K, through our proposed automated annotation pipeline. Furthermore, we develop a well-designed benchmark, GIQA-Bench. The benchmark comprehensively evaluates the model grounding-IQA performance from three perspectives: description quality, VQA accuracy, and grounding precision. Experiments demonstrate that our proposed task paradigm, dataset, and benchmark facilitate the more fine-grained IQA application. Code: https://github.com/zhengchen1999/Grounding-IQA.

Published: December 2024

Este artículo analiza los enfoques de innovación social (IS) en el presupuesto participativo de Pereira, Colombia (2016-2019), mediante un estudio de caso cualitativo. Basado en entrevistas, observaciones y contrastes teórico-empíricos, se identifica un enfoque híbrido “cívico-político” caracterizado por la agencia comunitaria territorializada, el abordaje estratégico de conflictos y la incidencia en la cultura política y gestión pública. Se concluye que este enfoque constituye una “innovación democrática” con potencial para democratizar la gestión local, aunque enfrenta desafíos de sostenibilidad y articulación con la planeación a largo plazo. El estudio aporta evidencia sobre la pluralidad de la IS y su rol en la transformación de relaciones de poder territorial, discutiendo implicaciones para fortalecer la democracia y la gobernanza en el Sur Global.
Evaluation of a yoga-based intervention for ICU nurse burnout
Authors: Hummel Garland
Published: December 2024

Background Burnout is endemic to nursing and carries high personal, institutional, and social costs. Methods Previous studies have demonstrated that yoga may alleviate burnout in healthcare workers. A yoga-based intervention was created specifically for ICU nurses. The program was offered to all nurses working in critical care environments through recruitment emails and fliers. 28 nurses participated, but a high attrition rate led to only 9 people completing both the pre-and-posttest survey. Power analysis of 30 participants was not met and statistical significance could not be established, however, differences illustrated by non-parametric testing indicate potential clinical relevance. Results Pre-and-posttest Maslach Burnout Inventory (MBI) scores were compared via Wilcoxon signed-rank tests. Depersonalization and Personal Achievement domains of the MBI showed no difference, but there was a difference in SUM and MEAN/AVE Emotional Exhaustion scores (Z = -2.129, p = 0.33) and (Z = -2.113, p= 0.035), respectively. NDNQI data were collected before and after the intervention to determine if there was a change in nurse-sensitive patient outcomes and assessed using Wilcoxon signed-rank tests, showing no appreciable difference. Conclusions This pilot program reinforced that yoga may be a useful intervention in addressing burnout, however, the high attrition rate suggests that it is likely not a feasible option for most nurses. IRB Approval IRB approval through expedited review. Co-Authors: Dr. Nancy Birtley, Dr. Miriam Butler, and Alexandria Phillips Objective The purpose of this QI project was to explore the efficacy and feasibility of yoga as an intervention for ICU nurse burnout.
