Published: December 2024

Background: Diabetic retinopathy (DR) is a significant microvascular complication of diabetes mellitus, leading to vision impairment and blindness in working-age adults globally.Aim: To evaluate the knowledge, clinical characteristics and associated factors among diabetic retinopathy patients attending an ophthalmology clinic at a tertiary hospital in Aceh from May 2020 to May 2021.Setting: The study was conducted at Zainoel Abidin General Hospital, Banda Aceh, Indonesia.Methods: A prospective cross-sectional study using consecutive sampling was conducted. Data collection involved patient history, eye examinations, laboratory tests and administering a questionnaire to assess knowledge of diabetes and diabetic retinopathy. The data were analysed using descriptive statistics and binary logistic regression.Results: Out of 173 participants, 170 were included in the study. A significant proportion had visual acuity less than 6/60 (44.1%) and proliferative diabetic retinopathy (PDR) (52.6%) with macular oedema in 11.8%. Only seven (4.1%) patients had good knowledge of diabetes and 28 (16.5%) had good knowledge of DR. A total of 113 (66.5%) patients were aware that diabetes could affect the eye and positively associated with the sex (adjusted odds ratio [AOR]: 6.18, 95% confidence interval [CI]: 1.80–21.21, P = 0.004), educational level (AOR: 4.66, 95% CI: 1.31–16.51, P = 0.017) and type of DM (AOR: 5.30, 95% CI: 1.97–14.26, P = 0.001).Conclusion: The study revealed a high incidence of vision-threatening diabetic retinopathy (VTDR), including severe non-proliferative, proliferative and significant macular oedema cases. However, patients’ knowledge of their disease was very low.Contribution: This study crucial data to the Department of Health Authority for policy decision-making.
Correlation between Interdialytic Weight Gain and Intradialytic Hypotension in Patients with Chronic Kidney Disease Undergoing Hemodialysis in Tertiary Referral Hospital
Authors: Tjempakasari Artaria , Prasanta Nitya , Aditiawardana  , Carrasco Magdeline Elizabeth
Published: December 2024

Introduction:

Chronic kidney disease (CKD) is a condition characterized by kidney damage or reduced function lasting at least 3 months. Hemodialysis (HD) is a key treatment for CKD, replacing kidney function in fluid and acid–base electrolyte balance, metabolic waste removal, and blood pressure management. Intradialytic weight gain (IDWG) is a common HD complication, with patients with limited systolic blood pressure having the highest risk of intradialytic hypotension (IDH)-related death. This research examined IDWG patterns in patients on regular HD.

Methods:

A prospective, observational study of 40 end-stage renal disease patients on regular HD twice a week at Dr. Soetomo Hospital was conducted for 3 months. Every patient received HD for at least 3 months. Data from purposive sampling. Statisticians used IBM SPSS® Statistics 25.

Results:

A total of 20 out of 40 IDWG subjects experienced IDH. In the IDH group, the percentage of women was 11 (55%) people, the mean age of the research subjects was 49.9 ± 9.70 years, the mean duration on HD of the research subjects was 70.5 ± 43.78 months, and the mean IDWG percentage (IDWG%) of the research subjects was 5.36 ± 1.1. By statistical analysis, a correlation value of P = 0.008 was obtained.

Conclusion:

There was a correlation between IDWG% and the incidence of IDH, with or without confounding factors such as gender, age, and duration of HD. The higher the percentage value of IDWG, the higher the IDH incidence rate.

Authors: Anhar Chairul , Perdana Rizka Fathoni , Yunus Mohd Razif Mohamad
Published: December 2024

Introduction:

Oropharyngeal dysphagia is a swallowing disorder in the oral and/or pharyngeal phase. The prevalence of oropharyngeal dysphagia is higher when there is the presence of comorbid conditions such as head-and-neck cancer (19%–81%) and neurological diseases (Parkinson’s [80%–100%] and stroke [19%–81%]).

Methods:

This retrospective descriptive study used medical record data from the outpatient clinic of the Otorhinolaryngology-Head and Neck Surgery Unit in the Broncho Esophagology Division of Dr. Soetomo General Academic Hospital from January 2018 to December 2019.

Results:

In total, 112 patients met the inclusion and exclusion criteria. There were more male (61.60%) than female (38.4%) patients, at a ratio of 1.6:1. The most common age group was 50–90 years old (66.0%). The most common chief complaint was choking (37.5%). The highest risk factor was stroke (25.9%). Preswallowing: velopharyngeal movement (14.4%), vocal cord movement disorders (28.6%), standing secretion (83.9%), penetration (38.4%), aspiration (24.1%), silent aspiration (15.2%), and impaired hypopharyngeal sensitivity (33%). Swallowing solid bolus test: residual (78.9%), penetration (23.2%), aspiration (18.9%), and impaired cough reflex (82.1%). Swallowing liquid bolus test: residual (76%), penetration (24%), aspiration (12.7%), and impaired cough reflex (91.1%).

Conclusion:

Men more than women are affected by this disease. The most common age group was >50 years. The most common complaint is choking. Stroke is the most common etiology. Impaired vocal cord movement, standing secretion, penetration, and silent aspiration were found on the preswallowing test. Residues are more common in solid boluses than liquid. Liquid bolus penetration is more common than solid. The aspiration of solid boluses is more common than that of liquid.

Published: December 2024

Background:

Malaria remains the deadliest parasitic disease and continues to cause more than half a million deaths across the world each year, mainly victims are sub-Saharan children. Malaria is a common reason for paediatric hospitalisation.

Objective:

The objective was to characterise malaria and describe the evolution after treatment in the paediatric department of the University Hospital Centre Amissa Bongo de Franceville.

Methods:

This was a cross-sectional study conducted from 1 February 2023 to 15 May 2023. A clinical and biological diagnosis was made in febrile children aged from 6 months to 15 years.

Results:

A total of 306 patients were included. The mean age was 50.4 ± 44.3 months, 94.3% had consulted within ≥48 h and self-medication was practiced by 83.3%. The prevalence of malaria was 17.3%. Fever ˃39°8C (adjusted odds ratios [aOR] = 2.68; 95% confidence interval [CI] = [1.32–5.48]; P < 0.01), chills (aOR = 2.14; 95% CI = [1.13–4.11]; P < 0.01) and nausea–vomiting (aOR = 2.03; 95% CI = [1.06–3.83]; P = 0.03) were the factors associated with the occurrence of malaria. The majority of children were treated for simple malaria with artemisinin-based combination therapy. A total of 16/53 was seen in post-therapeutic consultation. Of them, 2 patients had a positive thick drop.

Conclusion:

Non-compliance with preventive measures and the misuse of antimalarials further complicate the clinical picture, requiring parenteral management for the most part.
An Efficient Deep Learning Technique for Brain Abnormality Detection Using MRI
Authors: Mahajan Shilpa , Dhull Anuradha , Dahiya Aryan
Published: December 2024

This research proposes an effective and reliable deep learning method for detecting brain abnormalities via magnetic resonance imaging (MRI). The technique consists of two primary stages: first, a binary classifier that divides pictures into "Brain" and "Non-Brain" categories; second, multi-class classifiers that explicitly recognise categories such pituitary adenomas, gliomas, and meningiomas. The labelled and preprocessed data were taken from a collection of 7,753 pictures provided by Qhills Technologies Pvt. Ltd. Additional data from the Brain Tumour MRI collection was also incorporated to improve the model's generalisation skills. VGG-16 outperforms the other machine learning models, with an accuracy rate of 96.4%, when compared to ANN, CNN, VGG-16, and AlexNet. A thorough model evaluation and hyperparameter tweaking process was conducted using the accuracy, precision, recall F1-score. The findings of this study point to the potential of deep learning techniques in identifying brain disorders fast and precisely, opening the door to more precise diagnosis in clinical settings.
Properties of non-equilibrium steady states for the non-linear BGK equation on the torus
Authors: Evans Josephine , Menegaki Angeliki
Published: December 2024

We study the non-linear BGK model in one dimension coupled to a spatially varying thermostat. We show existence, local uniqueness, and linear stability of a steady state when the linear coupling term is large compared to the non-linear self-interaction term. This model possesses a non-explicit spatially dependent non-equilibrium steady state. For the existence and the local uniqueness we utilise a fixed point argument, reducing the study of the non-linear model to the linear BGK model, while for the stability we adapt the

L^{2}

hypocoercivity theory, yielding existence of a spectral gap for the linearised operator around this non-equilibrium steady state.
The branching number of intermediate growth trees
Authors: Amir Gideon , Yang Shangjie
Published: December 2024

We introduce an “intermediate branching number” (IBN) which captures the branching of intermediate growth trees, similar in spirit to the well-studied branching number of exponential growth trees. We show that the IBN is the critical threshold for several random processes on trees, and analyze the IBN on some examples of interest. Our main result is an algorithm to find spherically symmetric trees with large IBN inside some permutation wreath products. We demonstrate the usefulness of these trees to the study of intermediate growth groups by using them to get the first tight bounds for the firefighter problem on some intermediate growth groups.
The Descriptive Complexity of Graph Neural Networks
Authors: Grohe Martin
Published: December 2024

We analyse the power of graph neural networks (GNNs) in terms of Boolean circuit complexity and descriptive complexity. We prove that the graph queries that can be computed by a polynomial-size bounded-depth family of GNNs are exactly those definable in the guarded fragment GFO+C of first-order logic with counting and with built-in relations. This puts GNNs in the circuit complexity class (non-uniform) $\text{TC}^0$. Remarkably, the GNN families may use arbitrary real weights and a wide class of activation functions that includes the standard ReLU, logistic "sigmoid", and hyperbolic tangent functions. If the GNNs are allowed to use random initialisation and global readout (both standard features of GNNs widely used in practice), they can compute exactly the same queries as bounded depth Boolean circuits with threshold gates, that is, exactly the queries in $\text{TC}^0$. Moreover, we show that queries computable by a single GNN with piecewise linear activations and rational weights are definable in GFO+C without built-in relations. Therefore, they are contained in uniform $\text{TC}^0$.

Published: December 2024

Artikel præsenterer et udviklings- og forskningsprojekt med fokus på udvikling af tværsproglig didaktik på læreruddannelsen i Danmark. Projektet er organiseret tværinstitutionelt som et samarbejde mellem universitet, university colleges og grundskoler og med fokus på brobygning mellem læreruddannelse og grundskole. Projektet bringer tværsproglige tilgange – i en bred forståelse af tværsproglighed, herunder translanguaging (García-Mateus & Palmer, 2017; García, 2009), flersprogethedsdidaktik (Candelier et al., 2012; Daryai-Hansen et al., 2019) og tværsproglig didaktik (Krogager Andersen, 2020) – fra teoretisk og empirisk forskning til afprøvning først i læreruddannelsens praksis og dernæst i grundskolens praksis. Projektet er både tværsprogligt og tværfagligt i sin organisering, idet det går på tværs af sprogfagene dansk, dansk som andetsprog (DSA), engelsk, fransk, spansk og tysk, og det beskæftiger sig således også med overgange mellem sprog og sprogfag.
Artiklen introducerer først udviklingsprojektets formål, indhold, organisering og resultater og dernæst forskningsprojektets formål, datagrundlag (fx refleksionslogs, interviews, observationer), analyser og resultater i relation læreruddanneres, lærerstuderendes, grundskolelæreres og grundskoleelevers oplevelser og erfaringer i forbindelse med de tværsproglige forløb. Artiklen diskuterer dels (a) organisatoriske, faglige og epistemologiske muligheder og udfordringer, og dels (b) modstand, engagement, barrierer og muligheder med henblik på fremtidig udvikling af tværsproglige tilgange på læreruddannelsen.

Published: December 2024

Dans le cadre d’une recherche collaborative (RC) rattachée au site professionnel BILEM « Bilinguisme en maternelle et au cycle 2 » créé en 2019, des professionnel·les de l’école primaire, des chercheur·euses en didactique des langues de l’Université de Franche-Comté ainsi que le Centre académique pour la scolarisation des élèves allophones nouvellement arrivés et des enfants issus de familles itinérantes et de voyageurs coopèrent pour créer des ressources favorisant l’accompagnement des élèves, des familles et des professionnel·les inscrit·es dans des contextes de diversité linguistique et culturelle.
Un sous-groupe de travail questionne depuis 2021 les missions, les pratiques et le rôle professionnel des agents territoriaux spécialisés des écoles maternelles (ATSEM) dans l’accompagnement des élèves allophones et de leurs familles ainsi que dans la socialisation langagière plurilingue de ces élèves, en articulation avec le travail des professeur·e·s des écoles.
En nous appuyant sur diverses données de recherche, nous nous demandons en quoi l’engagement dans un groupe de travail pluri-catégoriel au sein d’une RC participe de la formation et du développement professionnel des membres impliqués·e·s. Cet article s’intéresse ainsi aux espaces de transitions, de continuité et de ruptures entre l’école, les élèves et les familles au niveau préscolaire en France.

Published: December 2024

L’article s’inscrit dans la continuité des travaux sur les approches plurielles en langues-cultures. Il prend appui sur des ressources pour l’évaluation de compétences en langues familiales recueillies et coconstruites dans le cadre d’un projet collaboratif avec les représentants de politiques éducatives de différents contextes européens. Ces ressources interrogent la place des langues familiales dans les systèmes éducatifs, au moment de l’accueil et tout au long du parcours de l’élève bi/plurilingue. De premières analyses des échanges au moment des étapes collaboratives du projet mettent au jour l’évolution des modèles en didactique des langues concernant l’évaluation des compétences en langues, croisant référentiels et outils à hauteur des répertoires plurilingues des élèves et visant à s’affranchir d’idéologies de domination et de minorisation des langues. Enfin, l’article questionne les méthodologies collaboratives de recherche permettant le décloisonnement des pratiques des acteurs de différents domaines professionnels en éducation (enseignants, personnels d’encadrement et direction, chercheurs) dans la coconstruction de savoirs et le partage de valeurs d’équité et de démocratie.
Flersprogethedsdidaktik som omdrejningspunkt på tværs af uddannelsesniveauer – erfaringer og perspektiver
Authors: Klimaszyk Petra
Published: December 2024

Forskning i sprogtilegnelse, flersprogethed og tværsproglig didaktik har påvist, at sprogkompetencer hænger sammen på tværs af sprog, og at sprogkompetencer på første- og andetsprog har stor betydning for tilegnelsen af yderlige sprog (Cenoz 2013). Flersproglig sprogundervisning kan positivt bidrage til udvikling af elevers sproglige bevidsthed, sproglig nysgerrighed og motivation for at lære fremmedsprog.
På trods af disse forskningsresultater dominerer den singulære tilgang stadig i det danske skolesammenhæng, som fokuserer på ét sprog, fx standardtysk i tyskundervisningen. Potentialet af pluralistiske tilgange, der inddrager hhv. flere sprog og sproglige varianter i undervisningen for at fremme elevernes flersprogede kompetencer, udnyttes ikke. Delvis gør det samme sig gældende i læreruddannelsen, selvom pluralistiske tilgange i et vist omfang bliver anvendt og formidlet. I det hele set tillægges disse tilgange dog endnu ikke den betydning, der er nødvendig for et paradigmeskifte i uddannelsessystemet og dermed bliver de ikke solidt forankret i (fremmed)sprogsdidaktikken på tværs af uddannelsesniveauer.
Projektet Tværsproglighed i Læreruddannelsen/TiL (2021-22) havde til formål at udvikle, afprøve og udbrede metoder for flersproglig undervisning som fremmer elevernes sproglige bevidsthed og indlæring i grundskolen.
I den her artikel præsenteres projektets forankring og gennemførsel på læreruddannelsen, konkrete eksempler med fokus på tyskundervisning i grundskolen og udvalgte projektresultater. Derudover fremlægges implementeringsmuligheder med henblik på den nye læreruddannelse i Danmark fra august 2023 (LU23), samt nogle skridt i retning af forankring af tværsproglighed som didaktisk princip i skolepraksis.

В статье представлены результаты исследования гипогликемической и  нейропротекторной эффективности производных 3-оксипиридина, содержащих остаток аскорбиновой кислоты,  – веществ с  лабораторным шифром ЛХТ-020 и ЛХТ-021. У крыс со стрептозотоциновым диабетом как ЛХТ-020, так и ЛХТ-021 продемонстрировали способность снижать уровень глюкозы в крови, при этом применение вещества ЛХТ-021 обеспечивало дополнительное снижение медианного уровня гликемии на 0,4 ммоль/л по сравнению с эффектом ЛХТ-020 к 14-му дню эксперимента. Показана также потенциальная нейропротекторная активность ЛХТ-021 за  счет снижения тканевого уровня фактора некроза опухоли альфа в головном мозге у крыс со стрептозотоциновым диабетом по сравнению с контролем на 5,52%. Более перспективное вещество ЛХТ-021, исследованное в тесте «Открытое поле» у крыс с экспериментальным нарушением мозгового кровообращения и, опционально, со стрептозотоциновым диабетом, способствовало ускорению нормализации поведенческих реакций и снижению уровня тревожности животных при сравнении с контролем. ЛХТ-021 потенциально обладает гипогликемическим, нейропротекторным (противовоспалительным) и, возможно, противотревожным эффектами.

The article presents the results of the study of hypoglycemic and neuroprotective efficacy of 3-oxypyridine derivatives containing ascorbic acid residue – substances code-named LHT-020 and LHT-021. In rats with streptozotocin-induced diabetes, both LHT-020 and LHT-021 demonstrated the ability to reduce blood glucose levels, with the use of LHT-021 producing an additional 0.4  mmol/L reduction in median glycemia compared to the effect of LXT-020 by day 14 of the experiment. The potential neuroprotective activity of LXT-021 was also shown by reducing tissue tumor necrosis factor alpha levels in the brain of streptozotocin-induced diabetes rats by 5.52% compared to the control. More promising substance LHT-021 was investigated in the Open Field Test in rats with experimental stroke and optionally with streptozotocin diabetes and resulted in accelerated normalization of behavioral responses and reduced anxiety levels of the animals when compared to controls. LHT-021 potentially has hypoglycemic, neuroprotective (anti-inflammatory), and possibly anti-anxiety effects.

Published: December 2024

Mobile phone addiction among university students in China has emerged as a significant concern, with its impact on mental health drawing increasing attention in academic circles. This study aims to delve deeper into the relationship between mobile phone addiction and mental health among students, exploring potential underlying mechanisms. A comprehensive cross-sectional survey involving 581 students from Huazhong University in Wuhan, China, was conducted to assess this phenomenon. Our findings indicate a negative correlation between mobile phone addiction and mental health. Furthermore, sleep quality appears to serve as a partial mediator in this relationship, suggesting that poor sleep quality may exacerbate the adverse effects of excessive mobile phone usage on mental health. These insights underscore the urgent need for university administrators, healthcare providers, and families to recognize and address the implications of mobile phone overuse among students. This study contributes to a better understanding of how mobile phone addiction could potentially disrupt mental well-being in the university student population.

In this study, the implementation of the prosumer concept in the distribution system of electrical energy will be thoroughly analysed, with a specific focus on the financial feasibility and sustainability of the model. The main emphasis will be on the formation of the monthly electricity bill, which requires a detailed evaluation of consumption and production on a monthly basis, taking into account tariffs and operational factors. Financial, operational, and societal aspects of this model will be analysed to assess its long-term viability and sustainability. Special attention will
be given to the variable nature of production from renewable sources, such as PV systems, and the feasibility of introducing electrical energy storage as an additional component in this model will be examined. Additionally, operational aspects of implementing this model in the distribution system will be scrutinized, as well as potential issues that may arise from improper implementation. Conducting a comprehensive analysis of the sustainability and profitability of this model in the long run is crucial, considering a wide range of factors that may influence the success and acceptance of this concept in the electrical energy sector

For the rational utilisation of available biomass resources for energy production, it is crucial to collect, process, and transport them at times when the energy potential is highest. Obtaining information on the type, location and quantity of available energy sources is slow and unreliable without a developed ENERGY MAP. Therefore, the creation of an ENERGY MAP for a given area is of great importance and serves the needs of interested companies and local self-governments. In this paper, the GIS software QGis and Geo Python are used to create a table that is constantly updated to create a GIS energy map of available biomass resources. The application of this methodology enables
efficient analysis and management of biomass resources. The generated map provides important information about the availability and locations of biomass resources, allowing for better planning and decision making regarding their utilisation for energy purposes. The paper describes the process of creating a form for users of available biomass feedstocks to determine the dependence of energy potential on the moisture content of the source resources, and the interpretation of the results by obtaining up-to-date data on the type and energy potential of waste biomass feedstocks at the source sites.

Regarding the legal consequences of unilaterally canceling a power of attorney in the case of working capital loans for construction, special requirements must be met by the bank when lending working capital for construction projects so that it is not canceled and sued unilaterally. This can be done with a power of attorney if it can be proven that the person giving the power of attorney is not carrying out their duties properly. The legal consequences of unilaterally revoking the special authority law are administrative sanctions and judicial revocation of the special authority law. Special requirements for granting working capital credit are met with two-way verification, especially for parties who provide special authority. This is to avoid further legal problems and the principal has the right to take legal action if his representative does not meet the requirements.

A procedure is developed for the calculation and experimental assessment of the operatonal modes damaging effect on the load-bearing structure of a dump truck body. The procedure makes it possible to determine the most dangerous zones of the load-bearing structure according to the multicycle fatigue criterion, as well as to assess the damaging effect of individual operatonal modes forming the dump truck working cycle. Analysis of the loading and fatigue damage accumulation of the load carrying structures of the BELAZ 7558 dump truck body was used for the procedure testing. Structure loadings have been determined for eight operating modes, including loading and unloading the body with bulk cargo during field tests. Processes of change of mechanical axial stresses during the tests were registered in eight zones. Experimental data analysis revealed two zones of the structure where the fatigue damage accumulation happens more than twice as fast as in the others. It is established that dump truck movement modes for technological road and the road in the dump area are characterized by the greatest fatigue damage accumulation. For the truck whole working cycle the most damaging movement mode for body is moving on the technological road. At the same time, the greatest unit equivalent fatigue damaging effect is formed by moving on the dump road and is greater than the corresponding value for the technological road by about 1.5 times. This is explained by the fact that the length of the technological road in the considered working cycle of the dump truck is 7 times more than the length of the dump road.

GEOMETRICAL ANALYSIS OF THE HINGE MECHANISM OF A CENTRIFUGAL LIFT SPEED LIMITER WITH TWO OUTPUT LINKS
Authors:   JSC “Mogilevliftmash”, KUTSEPOLENKO Alexander V. ,   Belarusian-Russian University
Published: December 2024

The article draws attention to the emergence of new promising designs of double-acting centrifugal speed limiters with a horizontal position of the axes of their devices controlling the excess speed, for example, the design of the speed limiter Vega, manufactured by Dynatech, with a horizontal position of the axis of its centrifugal device controlling the overspeed and the counter arrangement of its working bodies. The structural scheme of a similar speed limiter developed at JSC “Mogilevliftmash” is presented, which differs by collinear arrangement of the pulley and its centrifugal mechanism. The attention is paid to the absence in the free press of the design and calculation methodology of the above-mentioned speed limiters with the counter arrangement of the working bodies. The structural scheme is analyzed and attention is drawn to its asymmetry. The geometrical analysis of the articulated crank-and-rocker mechanism of the speed limiter with two output links (rocker arms) connected by connecting rods with a common input link (crank) is carried out. The dependences of the displacement of the output links on the angle of rotation of the input link are established for both parts of the mechanism, and their difference is confirmed. For the investigated speed limiter with specific dimensions of the mechanism links, the actual asynchrony of the displacement of the output links is determined. Attention is drawn to the necessity to ensure invariance of operation of the double-acting speed limiter regardless of the direction of rotation of its pulley. It is shown that non-synchronous movement of working bodies can lead to partial loss of functionality of the speed limiter and, accordingly, transformation of the double-sided limiter into a single-acting one. The problem of expediency of selection of possible variants of optimum combination of sizes of links of the mechanism is formulated for reduction of movement asynchrony of its output links and possibility of using the investigated structural scheme in precision mechanisms, in particular, in the double-acting centrifugal lift speed limiter.

The Problem of Peasant Identity in the Context of Migration
Authors: Mkrtchyan Arem
Published: December 2024

The transformation of traditional social networks to migration networks can be viewed as an undermining of traditional social cohesion between local community representatives. That is the modification of functional connections between community representatives or a disruption of traditional social ties and creation of new ties outside the community-formation of family networks on the principle of “transnationality”. By their nature these social processes do not only transform the existing social ties and relations in rural communities, making them transnational, but they also demonstrate the urgency of the problems inside the society, such as the weakening and distortion of social ties and relations, distortion of trust between the members of society, the loss of traditional identity of Armenian peasants, the attempt of community representatives to solve their economic problems through migration networks, by establishment of relations abroad.

Anomie, Social Alienation and Security in Armenian Society
Authors: Vartikyan Aram
Published: December 2024

The current era is distinguished by the unprecedented intensity of processes, changes, and developments, which partially condition the uncertainty, and social instability. The chaos of information flows, which is the source of permanent tensions, anxieties, fears deepens and brings about systematic continuity to them. The modern multidimensional man is the bearer of the many unpredictable risks resulting from the unstable, uncertain relations of the new century. In his turn, the modern RA citizen being the part of the above-mentioned processes is the bearer of the vulnerabilities and threats of the new system of values and norms, public relations, neo-liberal market economy, political management emerging parallelly with independence, as well as the ongoing Karabagh conflict. The mutilation of the institutional reproduction in the Armenian society, the deep social distrust and the large-scale individualization inherent to these conditions leave the citizens alone with their problems. As a result, only personal, limited strategies are formulated to resist, overcome and most importantly establish security, which deepens the social fragmentation, regulatory uncertainty, and instability. As a result, we lose the possibility to have a harmoniously collaborating social entity, which is of vital importance to the maintaining of the long-term security in Armenia

Estimating the Impact of Human Capital on Energy Efficiency in Developing Countries
Authors: Adilkhanyan Hayk
Published: December 2024

The current study is devoted to the examination and quantification of the influence that human capital exerts on energy sector, in particular on energy efficiency. Emerging countries are studied with a certain emphasis on countries of Commonwealth of Independent States (CIS). Overall, 85 countries are taken for the analysis. As a method of research, panel data analysis is selected. In this context, main panel and panel of CIS countries are estimated. The results reveal that human capital has a significantly positive influence on energy efficiency in case of both panels. Interestingly, for CIS countries that impact is stronger. Besides human capital, positive impact is received for the level of economic development. Conversely, negative effect on energy efficiency is evidenced for the level of industrialization and urbanization, and electricity consumption. For the sample of CIS countries, the impact of urbanization, however, is proved to be insignificant..
Knowledge Assessment in the System of Education: functional analysis.
Authors: Melkumyan Yuliana
Published: December 2024

Assessment of the knowledge gained by the learners is an important component of the educational process. The main purpose of education is not only the transfer of knowledge and traditions but also the continuous improvement of the ability to understand the world. The assessment as an educational tool should stimulate this aspiration towards improvement by assessing the past and constructing the better future. The following basic functions of the assessment are highlighted in the article: information, feedback, correction, motivation, self-esteem and ambitions formation, personal growth, monitoring, improvement of teaching methods, group dynamics and stratification. They are interdependent and all have dysfunctional risks that can lead to educational resistance. In order to avoid the latter, the rating should be used as a positive rather than a negative sanction in the educational system.

This article discusses some issues related to the program of sociological research, in particular, the requirements for defining the research problem and object. Referring to Soviet and post-Soviet Russian-language literature on sociological research, the author attempts to revise their definitions. The article expresses the idea that the object of sociological research is ultimately people because, without their social participation, no social phenomenon is manifested. The research problem is the question that the researcher raises when getting acquainted with a problematic situation. The author implies that the research problem carries a social contradiction. He develops the idea that the contradiction arises in the researcher's consciousness when he combines the problematic situation with his perceptions of the subject. It is then that a contradiction arises between his expectations and reality. The basis of sociological research is usually not a social problem, as many authors point out, but a research and scientific problem.

Authors: Melkumyan Yuliana
Published: December 2024

This article presents the analysis of the main approaches of professional orientation at high school and formulates recommendations for high schools of Armenia. The process of professional orientation is a major challenge for society as a whole and for the education system in particular. The objectives of this process are different, and often – contradictory. The most obvious purpose of the vocational guidance is the choice of the profession, which is the most suitable to pupil’s abilities. Secondly, it is about choosing a profession demanded by the labor market. Third, to ensure the economic, scientific and social development of the society, it is necessary to stimulate the choice of innovative professions. The separation of the senior classes of mainstream schools as an independent educational institution in RA aimed at the improvement of pupils’ professional orientation system. However, the high school faced different conceptual, organizational and methodological problems.
