Authors: Chaudhary Ankita , Solanki Jitender
Published: December 2023

Background:

Despite various initiatives, tobacco is still the largest global epidemic. The prevalence of tobacco use among stone crusher workers is very high because of their working pattern and lack of knowledge regarding the harmful effects of tobacco consumption.

Objective:

The objective of this study was to assess the knowledge, perceptions, and practice of tobacco use among stone crusher workers of Jaipur city.

Materials and Methods:

A cross-sectional community-based study was done on 250 stone crusher workers in and around Jaipur city selected by stratified cluster random sampling from 130 stone crusher plants in which each area was used as strata and stone crushers were selected randomly. They were assessed using predesigned and pretested questionnaires and analyzed using SPSS (19) statistical software.

Results:

Majority (98%) were tobacco users, out of which 68.40% consumed smokeless tobacco daily and 67.2% consumed smoke tobacco on a daily basis. Intention to quit the habit of tobacco among the stone crusher workers was 74.4%. Knowledge regarding health consequences of tobacco consumption among the workers was 42%, out of which 28% knew that tobacco causes heart attack and 22% knew regarding respiratory problems due to tobacco consumption. Opinion regarding introducing tobacco warning sign was found to be 34.4%.

Conclusions:

Tobacco use is an important public health problem worldwide, especially in developing countries like India workers in the stone crusher plant have a very high prevalence. Specific counseling and intervention programs are needed to reduce the burden of tobacco use-related morbidity among these workers.
Age, Reason, and Experiences Regarding the First Dental Visit among Children Belonging to Lucknow
Authors: Chowdhary Kritika , Saha Sonali , Sharma Anshul , Dhinsa Kavita , Sharma Prerna
Published: December 2023

Background:

According to the American Academy of Pediatric Dentistry guidelines, the first dental visit of a child is within 6 months of age. The need of such early visits is to help dentists to detect and treat incipient lesions, to educate parents about proper oral hygiene maintenance and the importance of diet and fluorides. Moreover, the visit helps the child to understand and adapt to the dental setup, thereby showing a positive dental attitude in future visits.

Aim:

The aim of this study was to find out the age at which children receive dental care for the first time and the reasons for such dental visits.

Subjects and Methods:

A cross-sectional study was conducted at the Department of Pedodontics and Preventive Dentistry, wherein a questionnaire was provided to the parents of pediatric patients attending the outpatient department for their first dental visit, which included the sociodemographic details along with the questions related to their first dental visit, reason, and experiences regarding their visit.

Results:

On average, children reported for their first dental visit only after 5 years of age for the complaints such as pain and dental caries. Thus, indicating oral health education and preventive treatment program are yet to reach the general population.

Conclusion:

From the present study, it was evident that necessary awareness regarding the first dental visit is very low, with the subjects approaching the dentist after the establishment of ill oral health, thus demanding interception rather than prevention of diseases.

Published: December 2023

INTRODUCTION:

The coronavirus disease 2019 (COVID-19) continues to have an enormous and extensive effect on global health, causing widespread devastation. Patients who have recovered from COVID-19 have an increased risk of thromboembolic disease. We suggest that soluble P-selectin and anti-platelet factor 4 (anti-PF4) plays a significant role in platelet activation, ultimately resulting in thrombosis. The purpose of this study is to compare the role of soluble P-selectin, anti-PF4, and platelet maximal aggregation levels in COVID-19 patients.

MATERIALS AND METHODS:

A cross-sectional study was conducted among COVID-19 patients who were admitted to the hospital between October 2021 and January 2022.

RESULTS:

From 160 individuals, we found that a number of individuals with older age (P = 0.014) and lower hemoglobin levels (P = 0.042) were significantly higher in the severe COVID-19 group compared to the nonsevere COVID-19 group. Remarkably, soluble P-selectin levels in mild-to-moderate COVID-19 were found to be significantly higher than the severe group, with statistical significance (P = 0.02). However, there was no significant difference in anti-PF4 levels between severe and nonsevere COVID-19 groups. Furthermore, platelet maximum aggregation was also significantly higher in the severe COVID-19 group than in the mild-to-moderate COVID-19 group by using 2.5 μM (P = 0.024), 5 μM (P = 0.026), and 10 mM adenosine-diphosphate (P = 0.02).

CONCLUSION:

Soluble P-selectin, an indicator of platelet activation, was shown to be significantly higher in mild-to-moderate COVID-19 group than the severe COVID-19 group. The maximum aggregation of platelets was also observed to be significantly greater in the severe COVID-19 group.
Counting embedded curves in symplectic $6$-manifolds

Published: December 2023

Based on computations of Pandharipande (1999), Zinger (2011) proved that the Gopakumar–Vafa BPS invariants

\mathrm{BPS}_{A,g}(X,\omega)

for primitive Calabi–Yau classes and arbitrary Fano classes

A

on a symplectic

6

-manifold

(X,\omega)

agree with the signed count

n_{A,g}(X,\omega)

of embedded

J

-holomorphic curves representing

A

and of genus

g

for a generic almost complex structure

J

compatible with

\omega

. Zinger's proof of the invariance of

n_{A,g}(X,\omega)

is indirect, as it relies on Gromov–Witten theory. In this article we give a direct proof of the invariance of

n_{A,g}(X,\omega)

. Furthermore, we prove that

n_{A,g}(X,\omega) = 0

for

g \gg 1

, thus proving the Gopakumar–Vafa finiteness conjecture for primitive Calabi–Yau classes and arbitrary Fano classes.
Матричное уравнение Кадомцева-Петвиашвили: тропический предел, отображения Янга-Бакстера и пентагона
Authors: Dimakis Aristophanes , Muller-Hoissen Folkert
Published: December 2023

Носителем решений матричного уравнения Кадомцева-Петвиашвили II в тропическом пределе в фиксированный момент времени является плоский граф с прикрепленными к его линейным частям "поляризациями". Исследуется подкласс солитонных решений, граф которых в тропическом пределе имеет вид корневого и в общем случае бинарного дерева, а также решения, у которых предельный граф состоит из двух взаимно перевернутых графов типа корневого дерева. Распределение поляризаций над линиями графа полностью определяется зависящей от параметров бинарной операцией и (нелинейным в общем случае) отображением Янга-Бакстера, которое становится линейным для векторного уравнения Кадомцева-Петвиашвили и, следовательно, задается $R$-матрицей. Зависимость бинарной операции от параметров приводит к решению уравнения пентагона, для которого выявляется некоторая связь с дилогарифмом Роджерса через решение уравнения гексагона, следующего члена семейства уравнений многоугольников. Оказалось, что полученное для векторного уравнения Кадомцева-Петвиашвили обобщение $R$-матрицы тоже удовлетворяет уравнению пентагона. При этом соответствующая локальная версия последнего приводит к новому решению уравнения гексагона.

Published: December 2023

Many countries pursuing malaria elimination implement “reactive” strategies targeting household members and neighbors of index cases to reduce transmission. These strategies include reactive case detection and treatment (RACDT; testing and treating those positive) and reactive drug administration (RDA; providing antimalarials without testing). We conducted systematic reviews of RACDT and RDA to assess their effect on reducing malaria transmission and gathered evidence about key contextual factors important to their implementation. Two reviewers screened titles/abstracts and full-text records using defined criteria (Patient = those in malaria-endemic/receptive areas; Intervention = RACDT or RDA; Comparison = standard of care; Outcome = malaria incidence/prevalence) and abstracted data for meta-analyses. The Grading of Recommendations, Assessment, Development, and Evaluations approach was used to rate certainty of evidence (CoE) for each outcome. Of 1,460 records screened, reviewers identified five RACDT studies (three cluster-randomized controlled trials [cRCTs] and two nonrandomized studies [NRS]) and seven RDA studies (six cRCTs and one NRS); three cRCTs comparing RDA to RACDT were included in both reviews. Compared with RDA, RACDT was associated with nonsignificantly higher parasite prevalence (odds ratio [OR] = 1.85; 95% CI: 0.96–3.57; one study) and malaria incidence (rate ratio [RR] = 1.30; 95% CI: 0.94–1.79; three studies), both very low CoE. Compared with control or RACDT, RDA was associated with non-significantly lower parasite incidence (RR = 0.73; 95% CI: 0.36–1.47; 2 studies, moderate CoE), prevalence (OR = 0.78; 95% CI: 0.52–1.17; 4 studies, low CoE), and malaria incidence (RR = 0.93; 95% CI: 0.82–1.05; six studies, moderate CoE). Evidence for reactive strategies’ impact on malaria transmission is limited, especially for RACDT, but suggests RDA might be more effective.

Published: December 2023

Malaria remains a significant cause of morbidity and mortality, even in low-transmission settings. With the advent of longer acting, more effective, and well-tolerated antimalarials, there is renewed interest in the efficacy of mass drug administration (MDA) to accelerate to elimination. We conducted a systematic review and meta-analysis to assess the efficacy of MDA to reduce the incidence and prevalence of Plasmodium falciparum (Pf) and Plasmodium vivax (Pv) infection. From 1,044 articles screened, 14 articles, including 10 randomized controlled trials (RCTs), were identified. Five included data on Pf only; five included Pf and Pv. Two of the Pf studies were conducted in areas of high–moderate transmission, the remainder were in areas of low–very low transmission. In higher transmission areas, MDA reduced incidence of Pf parasitemia (rate ratio = 0.61, 95% CI: 0.40–0.92; moderate certainty) 1 to 3 months after drug administration; no significant effect of MDA on Pf parasitemia prevalence was detected 1 to 3 months post-MDA (risk ratio [RR] = 1.76, 95% CI: 0.58–5.36; low certainty). In lower transmission settings, both incidence and prevalence of Pf parasitemia were reduced 1 to 3 months post-MDA (rate ratio = 0.37, 95% CI: 0.21–0.66; RR = 0.25, 95% CI: 0.15–0.41, respectively). Pv prevalence was reduced 1 to 3 months post-MDA (RR = 0.15, 95% CI: 0.10–0.24); there were no RCTs providing data on incidence of Pv. There was no significant effect of MDA at later time points. MDA may have short-term benefits; however, there was no evidence for longer term impact, although none of the trials assessed prolonged interventions.
Deep-PDANet: Camera-Radar Fusion for Depth Estimation in Autonomous
Driving Scenarios
Authors: Ai Wenjin , Ma Zhixiong , Zheng Lianqing
Published: December 2023

The results of monocular depth estimation are no satisfactory in the automatic
driving scenario. The combination of radar and camera for depth estimation is a
feasible solution to the problem of depth estimation in similar scenes. The
radar-camera pixel depth association model establishes a reliable correlation
between radar depth and camera pixel. In this paper, a new depth estimation
model named Deep-PDANet based on RC-PDA is proposed, which increases the depth
and width of the network and alleviates the problem of network degradation
through residual structure. Convolution kernels of different sizes are selected
in the basic units to further improve the ability to extract global information
while taking into account the extraction of information from a single pixel. The
convergence speed and learning ability of the network are improved by the
training strategy of multi-weight loss function in stages. In this paper,
comparison experiments and ablation study were performed on the NuScenes
dataset, and the accuracy of the multidimensional model was improved over the
baseline model, which exceeded the existing excellent algorithms.

Published: December 2023

LiDAR and camera fusion have emerged as a promising approach for improving place
recognition in robotics and autonomous vehicles. However, most existing
approaches often treat sensors separately, overlooking the potential benefits of
correlation between them. In this paper, we propose a Cross-
Modality Module (CMM) to leverage the potential
correlation of LiDAR and camera features for place recognition. Besides, to
fully exploit potential of each modality, we propose a Local-Global Fusion
Module to supplement global coarse-grained features with local fine-grained
features. The experiment results on public datasets demonstrate that our
approach effectively improves the average recall by 2.3%, reaching 98.7%,
compared with simply stacking of LiDAR and camera.
Real-Time Road Slope Estimation Based on GNSS/INS Fusion System
Considering Slope Change
Authors: Chen Mengyuan , Xiong Lu , Gao Letian
Published: December 2023

For intelligent vehicles, a fast and accurate estimation of road slope is of
great significance for many aspects, including the steering comfort, fuel
economy, vehicle stability control, driving decision-making, etc. But the
commonly used estimation methods nowadays usually demand additional sensors or
complex dynamic models, causing increase in system complexity as well as
decrease in accuracy. To solve these problems, this paper puts forward a
real-time road slope estimation algorithm leveraging the relationship between
pitch angle and road slope, which only requires low sensors cost and
computational complexity. Firstly, a GNSS/INS fusion system is established to
obtain the pitch angle with respect to the navigation frame, which couples the
vehicle’s pitch angle in vehicle frame and road slope angle. Then, based on the
different characteristics in frequency domain of the two components, frequency
domain analysis is conducted and low-pass filter is used to separate out road
slope signal. Besides, considering the slope change during driving, a parameter
adaption strategy is designed in order to timely track changes of slope
conditions. Experimental results show that the proposed method has a good
real-time performance and the average error is below 0.3 deg even when the road
slope changes rapidly.

Published: December 2023

In order to improve the efficiency of safety performance test for intelligent
vehicles and construct the test case set quickly, critical scenarios based on
graded hazard disposal model of human drivers are proposed, which can be used
for extraction of test cases for safety performance. Based on the natural
driving data in China Field Operational Test (China-FOT), the four-stage
collision avoidance process of human drivers is obtained, including steady
driving stage, risk judgment stage, collision reaction stage and collision
avoidance stage. And there are two human driver states: general state and alert
state. Then the graded hazard disposal model of human drivers is constructed.
According to the parameter distribution of natural driving data, the risk
perception point, risk response point and collision reaction time of
deceleration scenario and cut-in scenario are obtained, and the deceleration
gradient and the maximum deceleration of each collision avoidance difficulty
level are determined. For deceleration scenario and cut-in scenario, the
parameter range is determined to generalize logical scenarios. Then based on the
graded hazard disposal model of human drivers, the critical scenarios at the
preventable and unpreventable boundaries are obtained through simulation
calculation. As the concrete scenarios with high value for safety extracted from
the massive logical scenarios, the critical scenarios are used to construct the
test case set in the safety performance test for intelligent vehicles. For
deceleration scenario, 507 critical scenarios are obtained from 10,000 logical
scenarios, which increases the test efficiency by 19.72 times. For cut-in
scenario, 5,121 critical scenarios are obtained from 270,000 logical scenarios,
which increases the test efficiency by 52.72 times.

Published: December 2023

Most traffic accidents are caused by the driving behavior of drivers, so the study of driving behavior plays an important role in traffic safety. In this paper, we propose a comprehensive system for evaluating driver driving behavior safety, including classification and prediction of driver driving styles, as well as comprehensive scoring of driving behaviors. The driving behavior dataset needs to be pre-processed first. After that, we extracted driving behaviors and indicators, and performed cluster analysis on the reconstructed data to obtain three styles: conservative, aggressive, and impatient. We introduced a BP neural network to predict driving styles and obtained a relatively high prediction accuracy. Finally, we calculated the combined subjective and objective weights of the five behaviors and combined them with the developed scoring function to evaluate the driving safety of all drivers with a comprehensive score. The result was the selection of three driving behaviors that need priority attention and training.

Published: December 2023

This study provides a comprehensive examination of the conservation status of plant genetic resources in Yemen, with a particular focus on the national genebank, natural sites and ﬁeld genebanks. Employing a historical and descriptive approach, the study sheds light on the inception of ﬁeld inventories and collection surveys, the roles and contributions of various projects and institutions since the late 1980s, and the quantities of seed samples collected from different crop varieties and species. Additionally, the study highlights the challenges faced, especially during the last decade following the eruption of war in early 2015. Speciﬁcally, it emphasizes the detrimental impact of the war and sanctions, resulting in the loss of conserved seed samples, and the damage and sabotage of ﬁeld genebanks. In contrast, there is a need to ensure the enhancement of functioning seed systems and agriculture production even during times of conﬂict to reduce the impact of food insecurity. To conclude, the study puts forth several proposals, with a strong emphasis on expanding conservation efforts beyond natural sites, enhancing the capabilities for seed conservation in genebanks, and building genetic resources capacity.

Authors:   , Coons Shana
Published: December 2023

Practice Problem: Lack of proper sterile protocol for central lines was noted as a problem in the acute care units, causing CLASBI rates to be higher than the national average at the hospital in question. PICOT: In hospitalized acute care adult patients 18 years of age and older with central lines, how does the use of alcohol impregnated port protectors (AIPPs) compared to current central line sanitation practices affect central-line associated infections (CLASBI) within 10 weeks? Evidence: The literature evidence suggests that Alcohol Impregnated Port Protectors (AIPPs) decrease CLASBI rates and provide better outcomes for acute care patients with central lines. Alcohol Impregnated Port Protector (AIPPs) caps disinfect in one minute and provide a physical barrier to contamination and last up to seven days on central lines. Intervention: The Evidence-Based Practice Project established use of Alcohol Impregnated Port Protectors (AIPPs) vs standard of care for central lines (70% isopropyl alcohol prep pads on the central lines for an undefined period) on all patients in the acute care units with central lines (Emergency Room and Intensive Care) for 10 weeks. The use of direct observation and return demonstration was used to measure compliance. Weekly CLASBI rates from Infection Control were used to track the on-going rates during implementation. Outcome: Overall, this Evidence-Based Practice Project was clinically significant as it was able incorporate the use AIPPs vs lack of proper sterile protocol for central lines. The statistical data showed a decrease in CLASBI rates (8.02%) in as little as ten weeks. Conclusion: Central Line Infections are a great challenge in the healthcare system and AIPPs are a good way of curtailing those challenges. AIPPs promote evidence-based practice and uphold the safety standards by reducing CLASBI rates which ultimately reduce morbidity and mortality in acute care patients.

The aim of the study is to examine the relationship between body image and psychological resilience in individuals who do fitness as recreational activity. The study group consists of individuals residing in Sakarya who do fitness as recreational activity. In this context, a total of 197 voluntary participants, including 50 females (25.4%) and 147 males (74.6%), took part in the research. The data collection tools employed in the study included a Personal Information Form, Body Appreciation Scale (BAS), and Psychological Resilience Scale (PRS). The Personal Information Form gathered information on age, gender, years of exercise experience, weekly exercise frequency, and daily exercise duration. Skewness and kurtosis test results were examined to determine whether the scales were normally distributed. Based on the test results, it was established that the collected data exhibited normal distribution, and therefore, Pearson Correlation test was applied for the relationship analysis. Descriptive analyses involved calculating percentages, frequencies, and arithmetic means. The findings revealed a low-level positive correlation between BAS and PRS. Consequently, it was determined that as the body image scores of individuals who do fitness as recreational activity increased, their psychological resilience scores also exhibited an increase. As a result, as the body image scores of individuals who do fitness as recreational activity increase, their psychological resilience scores also increase.

Feminismos materialistas:
Authors: Bolla Luisina
Published: December 2023

El presente trabajo se concentra en dos inflexiones del feminismo materialista. La primera tuvo lugar en Francia en la década de 1970, de la mano de Christine Delphy, Nicole-Claude Mathieu, Colette Guillaumin, Monique Wittig y Paola Tabet. La segunda inflexión surge inspirada a partir de aquella y se desarrolló en Argentina desde fines de la década de 1970 hasta mediados de los años 80, gracias al impulso de Alicia Lombardi y Silvia García. El objetivo del artículo es recuperar la historia de los diálogos entre estas dos líneas de pensamiento. Para ello, comienza por situar los rasgos generales de las corrientes feministas materialistas, su inevitable polisemia y su multicentramiento. Luego, se concentra en la corriente feminista materialista que surge en Francia para sistematizar sus principales aportes teóricos. A continuación, se abordan las recepciones y las posteriores reelaboraciones que se realizaron en Argentina, entre fines de los años 70 y comienzos de la década de 1980. Finalmente, reflexiona sobre nuevas direcciones de análisis que se abren gracias a los intercambios transnacionales, a partir de la categoría de inter-historicidad.
nacimiento del tanatorio. Industria y arquitectura funeraria en España (1950-2000).
Authors: Dal Castello David
Published: December 2023

El objeto de estudio de este artículo es el tanatorio, un tipo de edificio funerario relativamente reciente que emergió de la creciente institucionalización de las empresas de pompas fúnebres durante la segunda mitad del siglo XX, y de la privatización de los servicios municipales ocurrida desde la década de 1990. Advertimos que en el marco de aquellos procesos se generaba un mutuo beneficio: mientras el negocio se renovaba con los nuevos edificios, las arquitecturas modernas encontraban una oportunidad de incursionar en un campo poco explorado. El estudio de estos nuevos programas arquitectónicos permite ampliar el conocimiento de los lugares de la muerte en las ciudades más allá de los cementerios, problematiza la incidencia de la industria funeraria en la cultura urbana, y sitúa el debate en torno a la idea de carácter en los edificios para la muerte.

Authors: López Calderón Carme
Published: December 2023

Los símbolos que la tradición ha aplicado a la Virgen María tienden a identificarse, en los estudios de cultura visual, como los “símbolos de las letanías marianas” o “símbolos de la letanía lauretana”. El presente artículo rastrea su origen en la patrística y su presencia en la Edad Media y Moderna, demostrando que su uso trasciende ampliamente las composiciones litánicas y ofreciendo una posible explicación para esta (mal)interpretación generalizada. Igualmente, propone sistematizar en cuatro grandes fórmulas la tipología general de Virgen acompañada de símbolos, al tiempo que evidencia cómo el significado de estos viene condicionado por la representación mariana que completan. Finalmente, aborda la presencia aislada de los mismos, planteando tanto qué pudo favorecer su autonomía, como la necesidad de cuestionarse dicha independencia.

Taking into account the trend of increasing interest in connecting solar power plants at the end customer's place, either for electricity exchange purposes or for commercial purposes, the question arises as to what percentage of users the opportunities in the electric distribution network allow to exercise this right. The subject of the research is the implementation of the PV hosting capacity analysis of the power distribution network with monitoring of voltage conditions and power losses on concrete examples of low-voltage and medium-voltage networks, which are typical for the Montenegrin distribution system, with the main goal of determining of quantity of power of solar power plants that the distribution network can receive depending on the capacity of the engaged network loads and network topologies. The results of the analysis indicate the need to change the legal solution by which the end customer has the right to connect the installed power of a small power plant that does not exceed the value of the connected power, as well as the need to create the optimal opportunities for the engagement of commercial solar power plants on the distribution system, both for users and for the distribution system operator.

Evropska energetika se kreće u smeru jedinstvenog evropskog tržišta električne energije sa sve većim učešćem obnovljivih izvora u proizvodnji iste. Direktiva Evropske Unije o obnovljivoj energiji daje jasno pravo građanima koji proizvode sopstvenu obnovljivu energiju da troše, skladište ili prodaju svoju generisanu energiju, uključujuć́i i ugovore o kupovini električne energije. U Srbiji su se prvo gradile solarne elektrane kao proizvođači električne energije, a kod krajnjih kupaca za sopstvenu potrošnju, jer nije bilo zakonski rešen kupac-proizvođač. Donošenjem seta zakona 2021. godine u Srbiji, počinje veća izgradnja solarnih elektrana u statusu kupca-proizođača. Rad proučava proizvodnju električne energije iz solarnih panela na teritoriji Vojvodine. Prvo su prikazani osnovni podaci o solarnim elektranama u statusu proizvodnje samo za sopstvenu potrošnju, kupca-proizvođača ili elektrane za proizvodnju električne energije za tržište. Upoređeni su rezultati realne proizvodnje električne energije više solarnih elektrana i analizirana je i njihova efikasnost. Nedostaje dugotrajno iskustvo u performansama i pouzdanosti solarnih elektrana, zbog nepostojanja programa praćenja. Prvi rezulatati pokazuju da efikasnost (proizvodnja kWh) nije kod svih solarnih elektrana na očekivanom nivou. To je jedan od razloga što je nezadovoljstvo kod nekih kupaca- proizvođača. Prikazani su podaci o mogućoj proizvodnji električne energije na različitim lokacijama koji se mogu naći na internetu. Izračunate su uštede koje su donele svojim vlasnicima i predlozi kako država da pomogne da se priključi što više solarnih elektrana na distributivni sistem. Povrat investicija u primerima je od sedam do deset godina i više. Vlada Srbije je izašla u susret, pa su kupcima- proizvođačima umanjene dažbine i ubuduće će imati manje račune i bržu isplativost investicija. Potrebno je nastaviti sa izmenama i dopunama zakona kako bi se olakšala realizacija izgradnje solarnih elektrana. Detaljna analiza kupaca-proizvođača će se moći uraditi tek posle jednog punog kruga rada od godinu dana i podrazumevala bi veći uzorak. Dalje investiranje u solarne elektrane najviše zavisi od ekonomske isplativosti, odnosno od efikasnosti.

Modern distribution networks are facing a series of challenges in terms of improving reliability parameters, utilization of existing capacities and integration of renewable energy sources, i.e. distributed generation. Consequently, the management of the distribution network, especially at the medium voltage level, gains additional importance. This paper describes the path from the idea to the realization of the medium voltage network automation and control system. The paper presents a brief description of the Smart Grid concept applied to the test case of the 6 kV Donja Ljubija distribution overhead line located on the territory of the city of Prijedor in the Republic of Srpska. The paper presents the key elements in the implementation of the proposed automation system: infrastructure planning (selection and positioning of switchgear), planning and implementation of communication infrastructure, selection and parameterization of failure indicators, and parameterization and adjustment of the SCADA system. With the support of Power Utility of Republic of Srpska, the complete system was successfully implemented and it is currently under regular operation. The results of this project can serve as guidelines for further automation of the MV network and as a basis for the development of advanced control algorithms.

During the monitoring, management and protection of electrical plants, networks and devices, regular measurement of various quantities is necessary. First of all, current and voltage measurements are basic. In this paper, attention is directed to voltage inductive transformers. The insulation is made of oil and it is necessary to regularly check the condition of the insulation in order to determine the need for its replacement. Of the many measurements that are made in practice, this paper will talk about insulation resistance and partial discharges in oil. Moisture and impurities mostly affect the dielectric properties of oil insulation. Oil-paper insulation with absorbed moisture is characterized by lower values of insulation resistance and polarization index. Aging of the insulation generally leads to a decrease in the insulation resistance, and to a certain extent to a decrease in the polarization index, especially if due to aging oil deposits are separated from the winding. Partial discharge is the phenomenon of multiple electrical breakdowns limited to some local area of the insulating material. Methods of measuring insulation resistance and partial discharges as well as reference values for assessing the state of insulation based on measured values are presented.

Information security represents very important segment in corporate networks as electric power one. Any form of endanger of basic propreties of information trasmitted and/or kept in these systems - confidentiality, integrity and availability - can have unforeseeable consequences for system, equipment or people security. That is why the issue of information security, even in our conditions, has recently been given considerable attention, as evidenced by the fact that more and more organizations within the power industry are deciding on a systematic approach to solving this problem through the application of standards from the ISO/IEC 27000 series, which refers to information security management systems (ISMS). In this paper, comparative analysis of revision of standard ISO/IEC 27001:2022 for Information Security Management System (ISMS) and the previous one ISO/IEC 27001:2013 is presented. Particular emphasize has been made to practical consequences of these changes of the standard, generally and within electric power systems, because of the fact that these systems nowdays are more vulnerable to different kinds of attacks than earlier. The purpose is to help organizations that have an ISMS certificate to make the transition to the new standard as painless as possible, i.e. organizations that are preparing to certify their ISMS according to the clauses of the new standard to understand them more easily.
