A Passenger Flow Prediction Method Using SAE-GCN-BiLSTM for Urban Rail Transit
Authors: Liu Fan
Published: December 2023

To address the problems of existing passenger flow prediction methods such as low accuracy, inadequate learning of spatial features of station topology, and inability to apply to large networks, a SAE-GCN-BiLSTM-based passenger flow forecasting method for urban rail transit is proposed. First, the external features are extracted layer by layer using stacked autoencoder (SAE). Then, graph convolutional network (GCN) is used to capture the spatial features of station topology, and bi-directional long and short-term memory network (BiLSTM) is used to extract the bi-directional temporal features, realizing the extraction of the spatio-temporal features. Finally, external features and spatio-temporal features are fused for accurate prediction of urban rail transit passenger flow. The experimental results show that the proposed method is higher than several other advanced models in the evaluation indexes under different granularities, indicating that the model effectively develops the accuracy and robustness of urban rail transit passenger flow prediction.

Published: December 2023

With its immersive, interactive, and creative capabilities, virtual reality (VR) has been widely used in educational settings to provide students with challenging real-world experiences. As a result, interest in its effectiveness has grown. The goal of this meta-analysis is to examine how VR technology affects students' motivation to study. A comprehensive analysis of the literature up to December 2022 revealed 15 randomized controlled trials or quasi-experimental studies. These studies were also coded to examine the moderating effects of their features, such as types of learner engagement, learner stages, learning domains, types of VR technology, and the moderating effect of knowledge types. The results indicate a large effect of VR on student engagement in learning (g=0.85). Furthermore, the findings of the moderator analysis demonstrate that VR has a more significant impact on cognitive engagement, higher education learners, immersive VR experiences, the field of art education, and procedural knowledge learning.

Authors: Kiriella K. K. C. S. , Karunadasa J. P. , Rodrigo W. D. A. S.
Published: December 2023

Majority electronic fan regulators available in the market feed significant amounts of harmonics into the fan, which leads to fan overheating and frequent failures of fan capacitors. This paper presents a design and development of a new electronic fan regulator that feeds negligible amounts of harmonics into the fan, and hence offers more reliable fan operation with smooth control and ripple free speed.The paper first reviews different forms of power electronic based control applicable to single-phase induction motors, and then identifies six topologies suitable for ceiling fans, based on the simplicity and cost effectiveness in meeting the performance targets. Final topology for the new design was selected after simulation of each short-listed topology to assess relative performances in terms of lesser harmonics, ripple free speed, smooth control, and cost. Finally, a prototype was built of the selected topology for a 70W single phase ceiling fan and test results verified the simulation results. Details of investigations, design, simulation, and test results are given and discussed.

Authors: Sasikala R. H. G. , Udayakumar K. A. C. , De Silva Narendra
Published: December 2023

The emergence of distributed generation has become significant over the last few years, bringing several challenges to traditional grid-connected electricity distribution systems. Technical limitations of integrating these new renewable distributed generation to the existing electricity grid made new avenues to change the way of energy consumption, which converted traditional consumers to prosumers. Peer-to-peer energy trading platforms enable these prosumers to trade electricity with their neighbours in microgrids where new electricity markets emerge with new technologies. This research introduces a concept of peer-to-peer energy trading for grid-connected electricity distribution networks. In its initial phase, the study models prosumer load sharing for households equipped with solar PV and battery energy storage. This modelling employs a Markov chain, where energy share states are determined by parameters in a Markov transition probability matrix. These parameters are varied during different time intervals of the day, reflecting varying cost components under a Time-of-Use (TOU) tariff structure. This approach enables prosumers to meet their load demand cost-effectively, fostering engagement in peer-to-peer energy exchanges. The proposed Markov model is simulated with 15-minute spot pricing intervals, demonstrating effective management of prosumer load demands in the peer-to-peer market environment, showcasing the potential benefits of this innovative energy trading approach.

Application of Edutainment Concepts and Tracking Emotions Based on Transient Emotion Peak in Online Education Systems
Authors: Jayasinghe Udeni , Athukorale Ajantha S.
Published: December 2023

Edutainment concepts such as Game-based learning (GBL) and ‘gamification’, pave the way for students to learn by experience by going beyond the traditional teacher-centred learning environment concepts. This paper is an attempt to investigate the feasibility of implementing a virtual learning environment by using “Edutainment” concepts to teach Computer Science subjects to undergraduate students in the Sri Lankan context while finding the most effective way out of GBL and gamification approaches in teaching and facilitating an online test environment to have frequent formative assessments to self-evaluate themselves. The first goal was to identify this student cohort’s preferred way out of GBL and gamification in learning. In this study, a game and a similar gamification approach were designed to teach a subject. Next, a qualitative analysis was conducted by collecting students’ feedback on each approach and a quantitative analysis was done to compare the effectiveness of the two approaches based on answers given to a quiz based on that subject. Under the second goal, it was found that effective feedback should address the emotional level of the student too. Hence, this study proposed a systematic way to track the emotional changes based on the transient emotion peak. We conclude, that adult students mostly tend to grab the core concepts rather than playing sophisticated games and though the proposed emotion tracking algorithm the emotions can be tracked at a promising accuracy level. In future work, we suggest that it would be better to use the proposed time interval to track the concentration level based on corresponding facial features.
Exploring the quality and safety issues in the coconut oil processing industry in Sri Lanka: A Review
Authors: Samarasinghe H. G. A. S. , Samaranayake U. C. , Dharmaprema G. A. D. B. S.
Published: December 2023

Coconut oil is a significant dietary component in Sri Lanka and serves as the primary source of fat for Sri Lankans, primarily used for culinary purposes. This review focuses on the quality and safety concerns within the coconut oil processing industry of Sri Lanka. The study collected data through interviews with industry personnel, conducted field visits to both small-scale and large-scale operations, and analyzed existing research. Several factors impact the quality and safety of coconut oil products. Key issues include the increase in free fatty acid content, the production of aflatoxin in copra, phthalate contamination from packaging, and the contamination of coconut oil with polyaromatic hydrocarbons (PAH). These quality and safety concerns result from cross-contamination with metals and other chemicals during equipment use, a shortage of trained personnel, insufficient laboratory testing of oil quality parameters before market distribution, and inadequate surveillance of small and medium-sized oil mills by regulatory bodies. Additionally, the local market faces high levels of adulteration, where coconut oil is mixed with lower-quality oils, stored improperly, or is of overall poor quality. Issues related to coconut cultivation include a decline in yields due to inefficient land usage, reduced productivity, climate change impacts, pest infestations, diseases, and increased production costs. The adulteration problem arises from the supply-demand gap for coconut oil in Sri Lanka and the high cost of producing one litre of good-quality coconut oil. The Sri Lankan government and the Sri Lanka Standards Institution have introduced a product standard for coconut oil production, outlining key parameters for the final product. Nevertheless, the absence of a comprehensive process standard affects quality control throughout production. Small and medium-scale producers lack awareness of SLSI standards, leading to non-compliance, along with an absence of regular quality and safety checks. Consequently, stringent enforcement is necessary to address these challenges. While improvements have been made, unresolved issues remain; therefore, a quality assurance system for the coconut oil processing industry is an urgent requirement, especially for small and medium-scale oil production facilities, which are key suppliers to the local market.

House flies (Musca domestica) have been identified as a mechanical vector, transmitting a range of infectious diseases, including cholera, shigellosis, salmonellosis, and skin infections. They live closely with human and domestic animals and are frequently found in areas of human activities. The present study was conducted to identify the pathogenic microbes potentially transmitted by houseflies since the related knowledge is not available in Sri Lankan settings. Houseflies were collected from the Malabe Medical Officer of Health (MOH) area from September - December 2022 using a prepared bait trap. Collected houseflies were identified up to the species level using standard identification keys. They were sacrificed using a cold shock and were washed in microcentrifuge tubes to collect the bacteria on their outer surface, in 250 µL sterile PBS. A dilution series (100- 10-7) was made from the original wash, and 200 µL from each dilution was plated on Plate Count Agar and pure cultures for each microbe were obtained. The isolated microbes were identified by performing Gram’s staining and biochemical tests. Acinetobacter spp., Enterococcus spp., Serratia spp., Klebsiella spp., Staphylococcus spp., Pseudomonas spp. and Escherichia spp. were identified and presumed as mechanically transmitted bacteria from houseflies. The most abundant bacterium was Staphylococcus sp. 2  (36.303%), followed by Escherichia sp. (21.452%) and Pseudomonas sp. (17.162%), while other bacteria were present in fewer proportions. The identified genera of the bacteria include some potential pathogenic bacterial species, which could cause mild to severe illnesses. Hence, the findings of the present study emphasized the importance of control measures for houseflies and community awareness programs to reduce the transmission of pathogenic bacteria.

The retina of zebrafish can regenerate completely after injury. Multiple studies have demonstrated that metabolic alterations occur during retinal damage; however to date no study has identified a link between metabolites and retinal regeneration of zebrafish. Here, we performed an unbiased metabolome sequencing in the N-methyl-D-aspartic acid-damaged retinas of zebrafish to demonstrate the metabolomic mechanism of retinal regeneration. Among the differentially-expressed metabolites, we found a significant decrease in p-aminobenzoic acid in the N-methyl-D-aspartic acid-damaged retinas of zebrafish. Then, we investigated the role of p-aminobenzoic acid in retinal regeneration in adult zebrafish. Importantly, p-aminobenzoic acid activated Achaetescute complex-like 1a expression, thereby promoting Müller glia reprogramming and division, as well as Müller glia-derived progenitor cell proliferation. Finally, we eliminated folic acid and inflammation as downstream effectors of PABA and demonstrated that PABA had little effect on Müller glia distribution. Taken together, these findings show that PABA contributes to retinal regeneration through activation of Achaetescute complex-like 1a expression in the N-methyl-D-aspartic acid-damaged retinas of zebrafish.

Authors: Attur Shylaja , Patel Jigar Kumar , Attur Kailash , Menat Sailesh
Published: December 2023

Keratocyst is a developmental odontogenic cyst arising from remnants/rests of the dental lamina with biologic behavior similar to benign neoplasm. The presence of multiple odontogenic keratocysts is rare and seen in Gorlin-Goltz syndrome (GGS). GGS syndrome presents with multisystem involvement and the classical triad of multiple basocellular epitheliomas, keratocysts in the jaws, and bifid ribs; that characterize the diagnosis of this syndrome. Multiple odontogenic keratocyst are the most consistent features of the syndrome in 65%–100% of affected individuals and are generally diagnosed at a very early age. Early diagnosis and proper counseling of the parent and patient might help to reduce the morbidity, encourage follow-up for timely treatment, and help in avoiding ionizing radiation that would lead to the development of malignancies.

Authors: Dev Gowtham , Thrivikraman Subhadra Kudukkasseri
Published: December 2023

Background:

An aging population is the most important medical as well as sociodemographic problem globally and countries have tried to address this problem by implementing various resources for healthy aging of society in general and an individual in particular in the form of various schemes and programs for the welfare of older persons. These resources are intended to provide a better quality of life for older persons.

Objectives:

The present study tried to comprehensively investigate the utilization of these resources by older people as well as the awareness about the availability of these resources and reasons toward poor utilization of such resources in Kerala.

Materials and Methods:

For this, a mixed method approach was employed involving a cross-sectional survey and qualitative inquiry, targeting 240 randomly selected participants across the state from randomly picked three different districts.

Results:

The key findings from the quantitative analysis were: Limited knowledge regarding the concept of Healthy Aging among respondents, moderate awareness of specific healthy aging resources, moderate utilization levels of resources, and a noteworthy 66.7% of participants expressing reluctance towards adopting suggested supportive resources for healthy aging. A significant association between socioeconomic status, residence, and awareness scores and a weak correlation between awareness and utilization scores were found out from the study. In the qualitative exploration, three principal themes emerged: Accessibility constraints, utilization patterns, and formulating an operational framework.

Conclusion:

This study underscores the need for tailored public awareness campaigns to foster resource utilization. The study challenges the practice of exclusively associating eligibility for resource access with socioeconomic class and disabilities. Ultimately, fostering healthy aging necessitates the active engagement and commitment of all stakeholders.

Authors: Suzuki Yuta , Suzuki Tomoto , Takagi Michiaki , Murakami Masayasu , Ikeda Takaaki
Published: December 2023

Background: This study examined the bidirectional and temporal-ordinal relationship between loneliness and back pain.Methods: Data from 7,730 participants in waves 6 (2012–2013), 7 (2014–2015), and 8 (2016–2017) of the national English Longitudinal Study of Ageing were analyzed. Back pain was graded on a scale of 0–10 (0, no discomfort; 10, unbearable pain). Loneliness was measured using the Revised University of California Los Angeles Loneliness Scale. A targeted minimum loss-based estimator was used to examine the bidirectional longitudinal associations between back pain and loneliness.Results: No loneliness in waves 6 and 7 (relative risk [RR]=0.76; 95% confidence interval [CI], 0.61–0.94), no loneliness in wave 6 but loneliness in wave 7 (RR=0.58; 95% CI, 0.50–0.68), and loneliness in wave 6 but not in wave 7 (RR=0.69; 95% CI, 0.57–0.86) were associated with significant risk reductions of back pain in wave 8 compared with the scenario of loneliness in waves 6 and 7. Mild back pain in wave 6 but moderate back pain (RR=0.55; 95% CI, 0.35–0.86) or severe back pain in wave 7 (RR=0.49; 95% CI, 0.34–0.72) showed a significant risk reduction of loneliness in wave 8 compared with severe back pain in waves 6 and 7.Conclusion: Loneliness may be a risk factor for back pain, and back pain may be a risk factor for loneliness. The results of this study will inform the development of more effective interventions for loneliness and back pain.

Frequent floods can contribute to the spread of various diseases and complications, some of which may result in diarrhea, especially among children. The current study aimed to find the determinants of diarrhea among children aged 1–6 years in flood-affected areas in Khyber Pakhtunkhwa, Pakistan. A cross-sectional study was conducted in flood-affected districts. Data regarding sociodemographic information related to diarrhea and anthropometric data were collected through a validated questionnaire. Logistic regression was used to find the determinants of diarrhea. In the presence of diarrhea, the prevalences found of stunting, wasting, and being underweight were 75.2%, 76.5%, and 74.1%, respectively, which is higher than those in children without diarrhea (stunting, 24.8%; wasting, 23.5%; and being underweight, 25.9%). In bivariate regression, children aged 2–4 years (odds ratio [OR] = 1.65, P < 0.05), large family size (OR = 7.46, P < 0.01), low income (OR = 2.55, < 0.001), bathing in ponds (OR = 3.05, P < 0.05), drinking of untreated water (OR = 3, P < 0.05), flooding (OR = 1.8, P < 0.05), children living in mud houses (OR = 1.5, P < 0.05), and usage of utensils without lids (OR = 1.96, P < 0.001) were significantly associated with occurrence of diarrhea. In multivariate regression, the identified risk factors (P < 0.05) for diarrhea in flood-affected areas included illiterate mothers, flooding, large family size, households without livestock, poor water quality, untreated water, and lack of toilet facilities. In conclusion, addressing the determinants of diarrhea identified in this study is crucial for mitigating the impact of frequent floods on children in flood-affected areas. Moreover, the higher prevalence of malnutrition underscores the urgent need for comprehensive strategies and proper water, sanitation, and hygiene programs to reduce the occurrence and determinants of diarrhea.

The Big Five Personality Traits and School Achievements of Children: The Role of Gender
Authors: Nikel Łukasz
Published: December 2023

The goal of the current study was to explore the relations between the Big Five personality traits and school achievements of children in the fourth grade of primary school. Participants were (n = 157) children (aged 9–11 years) attending public primary school in Poland. Children completed a self-description inventory for the Big Five and teachers evaluated current school achievements of children for mathematics and Polish language. The obtained results indicated that neuroticism and openness to experiences were significantly associated with school achievements. Moreover, the relationship between the Big Five and school achievements was moderated by gender in that a) agreeableness as well as the Big Five sub-scales of inferiority and helping behaviour were negatively associated with school achievements only among girls, and b) the openness to experience sub-scale of problem solver was positively associated with school achievements only among boys. The results suggest that the relationship between the Big Five personality traits and school achievements may depend on gender.
Model Checking Temporal Properties of Recursive Probabilistic Programs
Authors: Winkler Tobias , Gehnen Christina , Katoen Joost-Pieter
Published: December 2023

Probabilistic pushdown automata (pPDA) are a standard operational model for
programming languages involving discrete random choices and recursive
procedures. Temporal properties are useful for specifying the chronological
order of events during program execution. Existing approaches for model
checking pPDA against temporal properties have focused mostly on
$\omega$-regular and LTL properties. In this paper, we give decidability and
complexity results for the model checking problem of pPDA against
$\omega$-visibly pushdown languages that can be described by specification
logics such as CaRet. These logical formulae allow specifying properties that
explicitly take the structured computations arising from procedural programs
into account. For example, CaRet is able to match procedure calls with their
corresponding future returns, and thus allows to express fundamental program
properties such as total and partial correctness.
The Effect of Transfer of Care Protocol on the Rehospitalization Rates in Psychiatric Patients
Authors:   , Guillen Fernando
Published: December 2023

Practice Problem: The problem involved the transition of psychiatric care from long psychiatric hospitalizations to community-based psychiatric treatment which has developed into shorter inpatient psychiatric hospitalizations, which in turn has developed into a significantly higher number of individuals being readmitted within one year of inpatient discharge. PICOT: In adult patients undergoing inpatient acute psychiatric care (P), how does the use of a transfer of care protocol (I), compared to current transfer of care practice (C), affect the rate of readmission within 30 days for inpatient acute psychiatric care (O), in 10 weeks? Evidence: The evidence from an extensive literature review supported the implementation of the Brief Critical Time Intervention (BCTI) tool to reduce psychiatric patient readmissions. Intervention: The intervention for this evidence-based practice change project was the implementation of the BCTI tool. The intervention included training of staff to incorporate the BCTI as part of the discharge process. Outcome: The BCTI tool revealed an effective clinical impact on readmissions as evidenced by a readmission rate of 8%, which was lower than the pre-intervention rate of 8.9%. The result of the two proportions z-test was significant (p = 0.002), which indicates a significant difference between pre and post intervention readmissions. Conclusion: The intent of the project was to evaluate the efficacy of using the BCTI tool to reduce the readmission of psychiatric patients and provided clinically significant outcomes by having positive impacts on patient care and outcomes as the patients received improved discharge planning.

Published: December 2023

Architecture students and professionals had the opportunity to produce experimental spaces with the power of computer technologies, apart from traditional methods in space production. Technologies such as parametric design, Building Information Modelling (BIM), visual coding, and virtual reality hold new horizons for space production and the architecture itself. Despite all their potentials, they are still mainly used to support the design process or to present a project. The use of these tools is limited only to the effort to produce different and "impressive" forms based on aesthetic concerns. The study aims to examine the different possibilities of space production through digital space experiments. In this context, an experimental Virtual Reality (VR) application named “Desineer” was developed with Unreal game engine. The program has an easy interface where users can directly grab, drag, place and shape mesh objects. The Hands have played an important role in production throughout human history. Desineer eliminates the intermediary tools such as keyboard and mouse, with the help of VR technology, allowing the production of digital space directly by hands. By using the program, experiments were conducted on the manual production of digital space at Dumlupınar University Faculty of Architecture for students to gain new experiences. Within the scope of the study, first, discussions were held on space and the production of it for the students to develop their own ideas and perspectives, albeit fundamentally. Later, poems on different themes belonging to various poets were given to the students. The students read these poems and think about how the poems made them think and feel. Finally, the students produced improvised spaces based on these ideas and emotions using Desineer. It was observed that the workshop contributed students to the development of different perspectives on the production of space.
SUSTAINABLE DEVELOPMENT GOALS, EDUCATION AND PSYCHOLOGICAL WELLBEING: CHALLENGES AND WAY FORWARD
Authors: Yadav Dr Isha
Published: December 2023

In a momentous move, mental health was included in the United Nations Sustainable Development Goals in September 2015 as part of its 2030 Agenda. Emphasising the excessively high global burden of disease due to mental illness, the UN positioned mental health as a priority for global development. Consequently, promotion of mental health and wellbeing became a vital part of SDG 3 – Good Health and Well-being. Further, it is crucial in ensuring the achievement of several other SDGs such as No Poverty (SDG 1), Gender Equality (SDG 5), Reduced Inequality (SDG 10) amongst others. On World Mental Health Day 2023, the World Health Organization reiterated that “mental health is a universal human right” asserting that everyone everywhere has the right to the “highest attainable standard” of mental health. WHO further noted that it was impossible to accomplish sustainable development without attending to mental health. The National Education Policy, which was adopted by India in 2020, closely reflected these sentiments and took a holistic approach to learning. It highlighted the critical role played by educational institutes in ensuring emotional well-being and psychological health of students and impressed upon these institutes to create an inclusive and supportive environment conducive to psychological growth. This paper examines the rising trend towards appreciating the critical role of mental health in holistic education, sustainable development and growth. It assesses the provisions of the Sustainable Development Goals and National Education Policy that cater to this goal of facilitating mental health and inform policies of educational institutes. Actionable insights and policy recommendations are offered.

The result revealed that chalkboard 450(100%) and textbooks 300(67%) are the predominant instructional materials available. Chalkboard 450(100%) was found to be sufficiently utilized. The result further showed that instructional materials have significantly influence on instructional quality in public primary schools in Nigeria. This is because the calculated value (4.82) is greater than the critical value (3.84) at 0.05 level of significance. The study concluded that there is inadequate utilization of instructional materials with their attendant consequences on instructional quality in public primary schools in Southwestern Nigeria.
La teoría psicosocial de Jorge Veraza: lo subjetivo y lo psicológico en el capitalismo
Authors: Pavón-Cuéllar David
Published: December 2023

El presente artículo ofrece un esbozo de la teoría psicosocial del marxista mexicano Jorge Veraza Urtuzuástegui. La primera parte del texto pone de relieve la estructura de la teoría, sus diferencias con respecto a un modelo teórico psicológico, la relación de su objeto con la economía capitalista, su potencial interpelante-reflexivo para la psicología crítica y su poder explicativo para la elucidación de la subjetividad en el capitalismo. La segunda parte examina separadamente siete procesos generadores y determinantes de lo psicológico en la teoría psicosocial de Veraza: la fetichización, la transfiguración, la formación del sentido común, la erotización de las cosas, la famelización de las personas, la tanatización de la experiencia y la subsunción del psiquismo en el capital.

На основании изучения геологических отчетов, научных публикаций и марш- рутных исследований определены районы распространения разновозрастных пегматитов на территории Северного Кавказа. Описаны их разновидности, связанные с породами кис- лого, основного, ультраосновного составов, происхождение которых обусловлено поздне- магматическими и постмагматическими метасоматическими процессами, протекавшими преимущественно в апикальных частях гранитных массивов и над их кровлей, а также в массивах габброидов и ультрабазитов.Описаны коллекционные минералы и поделочные камни, встречающиеся в связи с пегматитами. Приведено краткое описание их наиболее типичных представителей. Отмечено, что на Центральном Кавказе в структурно-форма- ционной зоне (СФЗ) Главного хребта в связи с позднепалеозойскими гранитами «S-типа» распространены пегматиты с повышенным содержанием бериллия, олова, вольфрама и мышьяка. На Западном Кавказе в СФЗ Передового хребта, в связи со среднепалеозойскими гранитами «адакитового» типа, в пегматитах распространены минералы с повышенным содержанием стронция.

Based on the study of geological reports, scientific publications and route studies, the distribution areas of uneven-aged pegmatites within the territory of the North Caucasus were determined.Their varieties are described associated with rocks of acidic, basic, ultrabasic compositions, the origin of which is due to late magmatic and postmagmatic metasomatic processes that occurred mainly in the apical parts of granite massifs and above their roof, as well as in massifs of gabbroids and ultrabasic rocks. Collectible minerals and ornamental stones found in connection with pegmatites aredescribed.A brief description of their most typical representatives is given.It is noted that in the Central Caucasus in the structural-formational zone (SFZ) of the Main Range, in connection with the Late Paleozoic "S-type" granites, pegmatites with a high content ofberyllium, tin, tungsten and arsenic are common. In the Western Caucasus, in the SFZ of the Front Range, in connection with the Middle Paleozoic granites of the "adakite" type, minerals with a high content of strontium are common in pegmatites.

The paper presents the concept of replacing the existing thermal power plant Morava with facilities for the production, storage and combustion of green hydrogen. The facilities for the production of hydrogen would consist of an electrolyzer and a photovoltaic power plant, which is planned at the existing ash pit within the Morava thermal power plant. Hydrogen storage systems would also be part of the existing thermal power plant complex. The production of electricity would be carried out in a thermal power plant with a gas turbine powered by a mixture of hydrogen and natural gas, which would be built and connected to the power system at the site of the existing 110 kV substation. It would also be foreseen to use thermal energy that would serve for heating the households near the thermal power plant. Such a complex would enable the existing infrastructure of the Morava thermal power plant to be reoriented to the production of manageable green energy.

The method of calculating access to the electricity distribution system is a topic that has attracted the attention of the experts in the Republic of Serbia in recent years. This issue is more complex by the connection of an increasing number of new users to the electricity distribution system, such as prosumers or electric vehicle charging stations. Among the many challenges that the electricity distribution system operator faces in his work are finding ways to reduce electricity losses in the distribution system and the costs associated with them, as well as difficulties in system management due to the connection of new system users. Some of the challenges are the: need for the modernization of measuring infrastructure, the necessity for automation of the power grid and the need for necessary investments in the power system in order to enable the connection of new users. In this paper, proposals will be given for improving the process of collecting data from electricity meters and calculating access to the electricity distribution system. Existing legislation will also be analysed in order to enable the improvement of the regulatory framework for the purpose of implementing the proposed solutions. Examples from the reference international practice in this area shall be also presented. Additionally, data on the consumption of system users at the level of one distribution substation at the hourly and monthly level for the reference year will be considered. Based on the conducted analysis, a model will be developed for changing the process of collecting data from electricity meters and the method of calculating access to the electricity distribution system. The paper will also present the results of model testing on several relevant examples, and the impact of the model on the work of electricity distribution system operators as well as on system users and participants in the electricity market.
