Institutionalisation of Electoral Authoritarianism : A Study of The Syria’s Assad Regime
Authors: A M Keerthy
Published: November 2024

Authoritarianism is a prevalent form of political system in the world where democratic political ideals are limited through advocating strict obedience to a single ruler or group arbitrarily. Electoral authoritarianism is a form that falls between democracy and authoritarianism. They practice authoritarianism behind the institutional façade of representative democracy. The formal structures, guidelines, and practices that make up a political system evolve through a process called institutionalisation. Institutionalisation serves authoritarian regimes' purpose of establishing stability and legitimacy. Establishing long-lasting laws and policies to support the authoritarian government can institutionalise authoritarianism. Electoral authoritarianism became a major form of political system in the post-Cold War era. The institutionalisation of electoral authoritarianism is visible in various countries, especially in West Asia. Syria is the best example, which has a long history of institutionalisation of authoritarian practices. This was most visible during the period of Hafez al Assad in 1970 and continued during his son Bashar Al Assad’s tenure. This institutionalisation is practised by manipulating the country’s constitution, institutions like the army, Judiciary, media, political parties and electoral laws.

Comparing the Effectiveness between Human-generated Videos and AI-Generated Videos on Learning
Authors: Verma Shreyas , Leddo John
Published: November 2024

The present study investigates the relative effectiveness of AI vs. human-generated educational videos on learning. 19 students between the grades of 8 and 12 were given a video to watch on epigenetics, which they had no prior knowledge of. Eight of the students were given a Visla, an AI generative video platform, video on epigenetics while the other eleven were given a humancreated YouTube video on epigenetics. Both videos had the same content. After watching the video students were given a 20-question quiz to complete. Results showed scores on the post-test were virtually identical across the two groups. This suggests that AI-generated videos can be just as effective educationally as human-produced videos. As a result, AI-generated videos may represent a much more cost-effective way of delivering content and without sacrificing educational benefits.

In Krusevac Branch of Elektrodistribucija Srbije , consumers of electricity face problems with power limiters that are installed in switch cabinets, both in the buildings and in pole mounted meter boxes. During frequent control done by linemen, it is found that inadequate power limiters are installed in meter boxes. They are often of higher amperage and often the lineman discovers that the power limiter is fake. In order to solve this problem, the method of limiting the power is applied, by installing an insulated waterproof connector with an integrated power limiter. Installation of such a connector on the consumer's utility pole makes it is impossible for the consumer of electricity to manipulate with fake limiters in the meter box and in that way endanger EDS by using higher power than authorized. In Krusevac Branch, after installation of such connectors, there was an increased demand for increasing the authorized power at the metered supply point, because the current one, limited by the connector with integrated limiter, hadn’t meet the consumers’ needs. The selection of consumers on whose utility poles these connectors were installed was made after control of metered supply point and the lineman's report made at the metered supply point itself. Another group of consumers on whose utility poles it is planned to install connectors with an integrated power limiter, would be consumers that have smart meters with remote reading, where we would remotely read the maximum power during one month and thus determine whether the consumer has exceeded the authorized power. The effect of such power limiting is also of financial importance for EDS, which refers to the network fee paid by the consumer, the amount of which depends on the authorized power at the consumer’s metered supply point. In Krusevac Branch, if a consumer has an electric power permit for a maximum of 17,25 kW, which corresponds to power limiters of 25 A, a connector with an integrated limiter of 25A is also installed on the pole. Since the operating curve of this integrated limiter is significantly slower than the limiter in the consumer's switch cabinet, the limiter in the consumer’s switch cabinet will always react sooner. The paper itself will show the positive effect that the installation of the above-mentioned connector will have on the electric power distribution system (abbr. DEES) in terms of preventing misuse of the capacities of DEES, as well as in terms of financial benefits by increasing the network fee when a consumer’s authorized power is increased to the level of real value.

An isolated network is the simplest from the point of view of exploitation, and the cheapest investment from an economic point of view. The eastern and southern part of the Republika Srpska mostly has an isolated network, because there was no need for a grounded network due to sufficiently small values of capacitive currents. SS 110/35/10 kV Pale is specific, because the 35 kV isolated network has three overhead transmission lines, which means that the transmission lines generate small values of capacitive currents. The main goal of the work is the setting of directional and non-directional earth fault protection. Due to the small number of overhead transmission lines and the possibility that one transmission line alone remains in operation, except nondirectional earth-fault protection whose algorithm uses calculated zero current, non-directional earth-fault protection whose algorithm uses zero voltage should also be set. For the calculation of capacitive currents and voltages, it is necessary to know the capacities between phases and earth and the geometry of the poles. In the paper, the capacity of the 35 kV network was calculated, based on which the value of the capacitive current generated by each transmission line was calculated. Using the direct, inverse and zero scheme of the system, an expression for the zero voltage of the network was derived depending on the capacitive current and transient resistances at the fault location. The calculated values are sufficient for setting directional and non-directional earth fault protections.

This paper aims to indicate the effectiveness of the implementation of the battery system for energy storage (BESS) in achieving long-term system savings. During the modelling process, a microgrid consisting of diesel aggregates and solar power plants was taken into consideration and developed in line with a realistic island system. For the main role of batteries, their ability to cover the needs of the system reserve and balance out the daily disturbances caused by the inequality of production and consumption, was taken. The calculations were performed using the software program PLEXOS, with the support of the software for the analysis of solar systems - PVsyst. By demonstrating the cost-effectiveness and efficiency gains associated with the incorporation of BESS, this paper highlights the key role of energy storage systems in the future.

Renewable energy are the main driver and carrier towards carbon-neutral energy in the fight against climate change. Serbia has the potential of wind, sun, water, biomass and biogas, which enabled a major shift in the field of energy. This is indicated by the growing number of connected and planned power plants. Although the tendency to increase the use of energy from renewable sources is in accordance with the long-term strategic goals of the energy policy of the Republic of Serbia, for the connection of power plants to the distribution network and their participation in the overall power balance in Serbia, power plants must meet the technical conditions defined by the system operator as well as legal acts relating to this area. The technical conditions for the connection of the power plant should enable the normal operation of the power plant and the distribution network, without undermining the reliability of the supply and the quality of the electricity to all users of the system. For the connection and safe parallel operation of the power plant with the distribution network, the power plant must meet the criteria defined in the Rules on the operation of the distribution system. The entry into force of the Regulations on network rules related to the connection to the network of production units rules has brought the distribution of power plants into line with the importance of influencing the safe operation of the electricity system, and has defined a set of technical conditions that power plants need to satisfy in order to be able to connect to the distribution network, necessitating a review of the criteria and conditions for connection that have been applied so far in Serbia. In addition, the new provisions of the Law on the use of renewable energy sources are a introduced of restrictions, which directly affect the application of criteria for the connection of power plants to the distribution network. The goal of the work is to present the conditions for the connection of the power plants to the distribution network, as well as to show, through practice, how the amendments of the Republic of Serbia affected the correction of certain conditions.

Electrical tests of power transformers (hereinafter: PT) that are in operation are carried out within the deadlines set by regulations, standards or internal standards, in order to check the correctness and determine the condition of the insulation system. Electrical tests of PT in the field are also carried out in cases where there is a suspicion of failure due to the results of oil tests (analysis of gases dissolved in oil), thermographic tests, partial discharge tests, etc. Also, electrical tests of PT in the field are carried out after the operation of some protections in order to check the correctness of PT and determining the cause of the outage and the location of the failure. After the operation of the protection and suspected failure of the PT, a sample of oil is taken from the transformer tank and/or gas from the Buchholz relay, if there is gas, for the analysis of gases dissolved in the oil and/or gas analysis. In some cases, after the operation of the protection, the analysis of the gases dissolved in the oil shows that there is no malfunction in the PT, and then the cause of the outage due to the operation of the protection is sought elsewhere. In cases where the analysis of gases dissolved in the oil shows that there is a fault within the PT, electrical tests are carried out to determine the cause of the failure and locations of the fault. In the majority of such cases, electrical tests determine the cause and locations of failure, but there are also cases when electrical tests do not show PT malfunction, i.e. locations of the failure cannot be determined. The paper describes in detail three cases of PT failures in which electrical tests did not show PT malfunction and the location or locations of failure, that were determined in two cases after opening and inspecting the ET. In one case, the electrical tests of the PT did not determine the exact location of the failure, but the failure was confirmed by comparing the PT’s in failure winding capacitance results and another correct PT of the same type, and the exact location of the failure after opening the PT.

The On-Load Tap changer with associated motor drive unit is a demanding device for maintenance. Despite regular revisions and overhauls with the replacement of parts in the diverter switch of the On-Load Tap Changer, as they age, malfunctions occur more often on the On-Load Tap Changers and on the motor drive units of the On-Load Tap Changers. In motor drive units of On-Load Tap Changers, parts are generally changed only when necessary, i.e. after a detected malfunction in the motor drive unit. The paper describes the failures of the On-Load Tap Changers. Several special cases of failures in the switching part of the On-Load Tap Changers are discussed in more detail with photographs showing the location of the failure. The results of dissolved gas analysis arepresented. In the conclusion, a further way of carrying out the maintenance of On-Load Tap Changers and motor drives is proposed.

During the past years, there has been an increase in the number of power transformer failures worldwide linked by the presence of corrosive sulfur compounds in mineral insulating oil, leading to the formation of deposits of highly conductive copper sulfide or silver sulfide. In oils in operation, a highly reactive elemental sulfur, in a form of eight atom molecule of sulfur, S8, with a strong affinity for silver can be detected which present a significant threat to the contacts of the on load tap changer (OLTC). The high-temperature reactivation process of adsorbents during or after the regeneration process of mineral insulating oils leads to the contamination of insulating oil with elemental sulfur. The paper presents an innovative low-temperature process for the efficient removal of S8 from mineral insulating oil, based on the application of a small amount of iron particles coated with copper on its surface as a key component of the reagent mixture which is dispersed in polyethylene glycol. Intensive mixing of the reagent mixture with mineral insulating oil at temperatures below 100°C enables the complete removal of S8 from the oil. High process efficiency, the removal of S8 from the initial 15 mg/kg to levels below the detection limit, is achieved by using a small amount of the reagent mixture relative to the oil mass (<0.2 wt.%), in laboratory conditions and on a pilot scale experiments. Applying this process and subsequent treatment with adsorbents, insulating oils with improved physical, chemical and electrical characteristics are obtained, suitable for further use in power transformers. This procedure reduces potential environmental and economic risks associated with power transformer failures. The next phase will involve further process optimization and industrial plant implementation.

The paper presents software implementation of the method for short circuit current calculation through transformer windings given in the paper presented at CIRED Serbia Conference in 2022. The software is developed in the C# programming language. Commercial programs designed for short-circuit current calculations are predominantly oriented towards values in power lines i.e. location where relay protection is installed. The paper provides an overview of the possibilities for short circuit calculation through transformer windings that are available in widely used commercial software tools. During consulting services related to the equipment and the system of the new thermal power plant block unit, the necessity to check the stresses of the self-consumption transformers in the event of a short circuit appeared. The initial implementation of the method was in Excel. Self-consumption transformers are three-winding three-phase transformers, with a rated power of 68 MVA on the high-voltage side and with a rated power of 40 MVA at each of two 6 kV windings. The rated voltage for the high-voltage side and transformer connections of the first transformer is 110 kV, YNd5d5, and for the second transformer, 22 kV, Dd0d0. All types of faults on transformer terminals and different network topologies are considered. The new software, presented in the paper, is extended to include calculation for two-winding transformers. The paper presents the complete software implementation, including the input graphical user interface for transformer and network input parameters, as well as the output graphical interface for displaying calculation results.
CONSOLIDATION OF TECHNICAL DOCUMENTATION FOR THE CONSTRUCTION OF FACILITIES
Authors: Perić Dragoslav
Published: November 2024

According to the regulations for the construction of facilities, including all engineering and even electric power facilities, technical documentation is organized in up to six types of designes (for building permit, for execution, etc, which further contain the necessary projects of technological parts of the building (architecture, structures, electrical installations, etc and others (technical control, technical inspection, etc). All of these projects consist of textual, numerical and graphic documentation – which is produced using various software tools and packages (for word processing, spreadsheets, CAD, etc) – and for all projects is combined into a single electronically signed document / file. Consolidating such diverse documentation requires a lot of time and attention at the end of the designing process and usually relies on the use of word processing programs and for manipulation of documents in PDF format. This paper proposes an efficient concept and techniques of unifying technical documentation based on the application of programs for tabular calculations and simple tools for working with PDF documents, proven in many years of practice. The textual documentation also contains a large number of structured alphanumeric data that appear in a large number of places in all projects design types and parts, and with small variations. Programs for tabular calculations allow the formation of a set (base) of data so that they are entered only once, and applied to all necessary places in the documentation. The proposed concept achieves significant time savings for the preparation of technical documentation.

Published: November 2024

This paper proposes an approach for distribution network development planning in the presence of load and distribution generation uncertainty. The proposed approach is based on Relative Distance Measure interval arithmetic, mixed integer linear programming, and risk analysis. It enables obtaining a set of development plans that are evaluated considering the possible outcomes due to load and generation uncertainty. The best among them is selected by employing the Hurwitz criterion for measuring risk, which enables modelling of different decision maker’s risk preference. Hence, the proposed approach provides a decision-maker with a means for obtaining the development plan that will respond most efficiently, whatever future occurs.

During the current energy crisis, electricity prices on the markets have reached unprecedented levels, and power utilities in the region are making every effort to reduce citizens' consumption for the purpose of exporting and selling surpluses on international electricity markets, often by encouraging the use of renewable energy sources (OIE). The majority of OIE are connected to the electric power distribution network (EDM), known as distributed generators (DG). In such circumstances, the planning and development of the electric distribution network are conditioned by considering all aspects of EDM operation with a large number of dispersed DG. On the other hand, the EU requirements and international obligations of Southeast European countries in the energy sector are largely contained in the provisions of the Treaty establishing the Energy Community, gradually adopting the EU ACQUIS, i.e., by implementing the relevant directives and regulations of the EU in the field of electricity, renewable energy resources, and statistics. The purpose of this paper is to emphasize the importance of applying technical criteria related to the connection and parallel operation of distributed generators with the distribution network, to which BiH has previously committed, in order to enable planning and proper operation of the ED network in the newly arisen circumstances.

The calculation of the number of photovoltaic panels in solar power plants is limited by the allowed power that the plant can deliver to the electrical power system, as well as the area planned for the construction of the solar power plant. According to previous experiences, special attention needs to be devoted to the calculation of thenumber of photovoltaic panels connected to inverters. In this paper, using a specific example of a ground-based solar power plant with a capacity of 1 MW, a detailed calculation of the power of photovoltaic panels connectedto inverters is presented. The impact of the maximum and minimum number of photovoltaic panels, i.e., the maximum and minimum DC power distributed on each inverter individually, is analyzed. The calculation of electricity production on the AC side depending on the power in photovoltaic panels is presented in tabular form. Based on the calculations, i.e., the minimum and maximum power in photovoltaic panels, the optimal number of panels per inverter is defined for the given power plant. The aim of the paper is to emphasize the need for a detailed calculation of the number of panels per inverter, with the goal of the most efficient utilization of inverters in terms of electricity production during the operation of the solar power plant.

The foundations for the development of healthy lifestyles, habits, and health behavior are laid at an early, preschool age, hence the increasingly important role of the prevention programs. The aim of this research is to derive pedagogical recommendations and implications for future research based on the analysis of preventive programs developed to prevent and suppress health behavior problems in preschool children. A search of the key descriptors “preschool preventive programs”, “health and physical education”, “health behavior”, and “preschool institution” or “kindergarten” in the ERIC, PubMed and Google Scholar databases published between 2014 and 2023 determined the research sample (N = 30). The theoretical analysis method and the technique of content analysis were implemented, and a special research instrument was created – content analysis matrix. In order for the long-term effects of preventive activities to become visible, the following are necessary: a joint action of the preschool institution, family and local community; the starting point of prevention programs creation should be based on knowledge from reference sciences, necessary for understanding the health behavior problems of preschool children, as well as prevention; аpplication of varied work methods and forms of learning, adapted to the age of children and socio-cultural particularities of the environment and the institution itself; and finally, acting in different areas of development and preschool education. In future research, the focus should be shifted toward feasibility and relevance of the programs, evidence of their scientific and practical viability, as well as evaluation of the prevention programs implementation process.

In order to draw attention to the most significant issues related to the development of preschool inclusive education in Serbia, this paper considers the problems of early childhood inclusion from the scientific and research perspective. The paper discusses the theoretical and problem-based approach to research and investigation of early childhood inclusion. The analysis includes papers published in national journals of pedagogy or in conference proceedings after the introduction of inclusive education in our country (from 2009 to present). The results of the research show that the authors have mostly been concerned with the problems regarding a critical analysis of conceptual discourse and inclusive education practice, preschool teachers’ evaluation of inclusive education, as well as the evaluation of their competencies for inclusion, and the least with programmes and strategies for early support in a modern inclusive kindergarten and the effects of early inclusion on preschool children’s development. Pedagogical implications refer to the need for initiating research in which early inclusion would be regarded as a multidimensional problem and a method of an early intervention, and also to the need for research approaches to include all aspects and participants of preschool inclusive education, with the aim of indicating the further direction of the improvement of the idea and practice in early childhood inclusion.

In this paper, the importance of considering children's reception, their thinking and intuitive cognition as a special quality when processing characters in children's stories is emphasized. The paper emphasizes the necessity of using a comprehensive methodical approach to the processing of characters by combining 12 major interpenetrating elements that are given priority over the informative text being read and processed in class. The necessity of applying analytic-synthetic procedures is explained, by respecting the mutual connection and mutual influence of children's perception and reception. The delicacy of the processor's approach and the selection of the right measure in the interpretation and analysis of the characters in children's stories is shown in the form of possibilities that stand before the processor outside the existing didactic-methodical apparatus.

Polypharmacy is the simultaneous use of drugs with 5-9 drugs. Excessive polypharmacy is the simultaneous use of drugs with ≥ 10 drugs. Chronic diseases that are commonly suffered by geriatric patients are prone to causing a person to receive polypharmacy or excessive polypharmacy. This study aims to eval_uate polypharmacy and excessive polypharmacy in inpatient geriatric patients, by knowing the factors that may trigger a person to receive polypharmacy. The research uses a cross-sectional study method, using medical record data for the period January to December 2023. The part studied was in the form of sociodemographics, disease history and treatment of patients, as well as length of stay. From the research conducted, the results were obtained from 295 patient data samples with 141 patients (47.8%) and 154 patients (52.5%) were female. The age of patients consisted of 60-74 years old 192 patients (65.1%), 75-90 years old 100 patients (33.9%), and ≥ 90 years 3 patients (1%). The last education of the highest patient with a high school background was 101 patients (34.2%), the highest marital status was married as many as 245 patients (83.1%). The diagnosis of the third disease has the most patients, namely diabetes mellitus as many as 95 patients (15.5%), anemia as many as 70 patients (11.5%), and hypertension as many as 56 patients (9.2%). The preval_ence of polypharmacy in geriatric patients was 115 patients (39%) and excessive polypharmacy was 180 patients (61%). Broadly speaking, the sociodemographics of patients do not have a relationship with the occurrence of polypharmacy and excessive polypharmacy. The patient's clinical condition has a relationship with the occurrence of polypharmacy and excessive polypharmacy, this is evidenced by a p value of 0.000 (<0.05). The length of hospitalization and diagnosis of the patient's disease is a predictor of polypharmacy and excessive polypharmacy.

Background: Testicular torsion is a urological emergency caused by a twist of spermatic cord, which result in testicular tissue ischemia and requiring immediate surgery. The incidence occurred generally in children and adolescents, rarely found in adults. Severe Scrotal pain is the most common manifestation of testicular torsion. The definitive treatment for testicular torsion is surgery, either one of orchidopexy or orchidectomy. The prognosis of testicular torsion depends on the onset of symptoms and the decision time for surgery. Case Report: A 52-year-old man presented to emergency department with a history of gradual severe right-sided scrotal pain (visual analogue scale 8) radiated to the right groin in the last 3 day before admission. Previously, the patient's genitals were hit by the table. On physical examination, the testicles were found to be asymmetrical, swollen, redness, tenderness, and the testicle felt hard and immobilized, either the cremaster reflex or the Phren sign test were negative. The TWIST score was 6 (high risk for testicular torsion). Orchidopexy and orchidectomy were performed immediately without Scrotal Doppler Ultrasonography due to operational problems. Histopathology examination of the orchidectomy specimen impression showed an inflammation sign with exudative fluid presentation. Conclusion: Gradual Severe scrotal pain manifestations should be suspected as testicular torsion as soon as possible before it evolves into later phase. One of the causes of late phase testicular torsion is late admission to Hospital. Surgical emergency action should be taken considering theemergency state without waiting for ideal sonography

Early childhood development is a crucial period in the formation of a child's physical, cognitive, and emotional growth. Parental upbringing plays a significant role in supporting a child's development during this phase.** This study aims to analyze the influence of parenting styles on the early childhood development at Taman Kanak-Kanak (TKK) Kasih Mulia Cimahi. The background of this research is based on the fact that many parents do not fully understand how the parenting styles they adopt affect their child's development, especially during the early years, which are critical for the growth of various aspects of a child's development. The purpose of this study is to examine the relationship between different types of parenting styles—authoritative, authoritarian, permissive, and neglectful—and their effects on the physical, social, emotional, and cognitive development of children. A quantitative method with a survey approach was employed for this research. Data were collected through questionnaires distributed to 50 parents whose children attend TKK Kasih Mulia Cimahi, along with direct observation of the children's development. The data analysis technique used was regression analysis to determine the influence of parenting styles on various aspects of child development. The results showed that the authoritative parenting style had the most positive impact on all aspects of child development, particularly in social and cognitive growth. Conversely, authoritarian and permissive parenting styles tended to have negative effects, especially in the emotional and social development of the children. Neglectful parenting had the most detrimental effect on the physical and emotional development of the children. The conclusion of this study is that parental upbringing significantly influences early childhood development. Parents who adopt an authoritative parenting style are more likely to have children who grow and develop optimally. The recommendation is for parents to better understand the importance of applying balanced parenting, such as the authoritative style, which can holistically support a child's development. Additionally, schools are encouraged to provide education to parents on the importance of parenting in supporting early childhood development.
