Authors: Revanth RB  , Rajeswari  , Deepti Naik  , Yashas Ullas L  , Suraj HS  , Nikhilendra Reddy AVS
Published: August 2022

Background: Plantar fascitis causes heel pain and the thickened fascia has specific morphological features that can be utilized for early diagnosis through sonoelastographic evaluation.
Aims and Objectives: This case–control study was conducted to find out the role of sonoelastography in the diagnosis of plantar fasciitis (PF).
Materials and Methods: A case–control study was conducted in the department of radiodiagnosis in a teaching medical college. Thirtyclinically diagnosed PF patients and thirty controls were recruited based on selection criteria. Shear wave elastography (SWE) was done for all participants and the thickness of plantar fascia and strain ratio was compared between the groups. Plantar fascia thickness (mm) and elasticity (stain ratio) were considered as the primary outcome variable. coGuide software was used for data analysis.
Results: The mean age of the cases was 46.73±16.92 years and controls was 47.5±16.1 years. There was no statistical difference observed between cases and controls in age, sex, and body mass index. There was a statistically significant difference in thickness of the plantar fascia (P<0.001) between cases (4.18±0.77 mm) and controls (3.33±0.71 mm). The difference in strain ratio between study groups was statistically significant (P<0.001). The strain ratio had excellent predictive validity with the area under the curve of 0.929 (P<0.001). Data were analyzed using co-Guide software, V.1.03.
Conclusion: Ultrasound elastography can detect the thickening of the plantar fascia and strain ratio has excellent predictive validity in predicting PF.

Authors: Sarmistha Barua  , Aparna Chakrabarty  , Amrita Samanta  , Animesh Naskar
Published: August 2022

Background: Placental abruption (PA) contributes almost 30% of the all cases of antepartum hemorrhages. Both mother and fetus are at huge risk of maternal and neonatal morbidity and mortality when mother is complicated by this obstetric condition.
Aims and Objectives: The aim of this study is to find out the incidence and the fetomaternal outcome in the patients of abruption placenta.
Materials and Methods: A descriptive and observational study was conducted in the Department of Obstetrics and Gynaecology, in a tertiary teaching hospital in Kolkata, between January 01, 2018 and July 31, 2019, after obtaining ethical approval from the Institutional Ethics and Review Committee of R G Kar Medical College (reference number: RKC/Ethics/05). By convenience sampling method, we included 114 cases with gestational age of 28 completed weeks or more and diagnosed to have abruption placenta either clinically and/or ultrasonically. Statistical Package for the Social Science version 20 was used for analysis. Point estimate at 95% confidence interval was calculated along with frequency, percentage, mean, and standard deviation.
Results: The mean age of mothers was 25.19±5.56 years. The incidence of PA was found to be 0.99% (1.18–0.8154 at 95% confidence interval) among deliveries conducted in this hospital. The majority of women 78 (68.42%) were mixed type and 57 (50%) found at 36 weeks or more gestational age. Most common presentations were vaginal bleeding 108 (94.74%) followed by pain abdomen 74 (64.91%). Most women 103 (90.35%) underwent cesarean section. Postpartum hemorrhage occurred in 10.53% and 73.68% cases needed blood transfusion. Fetal outcome included preterm (50%) and neonatal intensive care admission (24.56%), still born 6.14%. 
Conclusions: PA is unpredictable and not preventable but morbidity and mortality can be reduced by adequate antenatal care, early detection and monitoring of risk factors, improved nutrition status and multidisciplinary management and timely admission with facilities of neonatal intensive care unit support.

Authors: Bhupendra Kumar Jain  , Ashwin Songra
Published: August 2022

Background: Cigarette smokers have a lower level of pulmonary function and physical fitness than non-smokers. Very little information is available for the short-term effects of smoking to lungs of asymptomatic smokers.
Aims and Objectives: The main focus of this study is to evaluate short duration toxic consequences of smoking to the lungs of asymptomatic smokers through spirometry and 6 min walk test (6MWT).
Materials and Methods: The present study is an observational cross-sectional study conducted in a tertiary care hospital which includes 160 individuals, 80 smokers and 80 non-smokers. The spirometric variables and 6MWT were performed to quantify smoking exposure. The whole statistics was analyzed using SPSS 21 and the mean between two groups was compared after applying standard Chi-square test. The means across more than 2 groups were compared after applying the standard analysis of variance (ANOVA) test.
Results: Most of lung function parameter such as forced expiratory volume in 1 s (FEV1), FEV1%, FEV1/forced vital capacity % (FVC%), maximum mid-expiratory flow 25–75%, peak expiratory flow rate (PEFR), PEFR%, and maximum voluntary ventilation % is decreased significantly in asymptomatic smokers than non-smokers except FVC and FVC%. The 6MWT distance is also reduced gradually and significantly in asymptomatic smokers from 1–5 pack-years to 15–20 pack-years.
Conclusion: Lung function parameters and 6MWT decreased significantly in asymptomatic smoker with increased quantum of pack-years. Therefore, early screening of high-risk smokers would lead to reduction of the clinical disease.

Authors: Chandrakoshi Gautam , Sanjuna D  , Patidar Ajay , Singh Nikita
Published: August 2022

Background: Fine-needle aspiration cytology (FNAC) of the salivary glands is a well-established technique that aids in pre-operative identification of abnormalities and to distinguish between neoplastic and non-neoplastic salivary gland lesions. Milan system for reporting of salivary gland cytology uses a standardized tiered system for categorization of salivary gland lesions.
Aims and Objectives: The present research was aimed to study the prevalence of various salivary gland lesions cytologically and classify them based on the Milan system.
Materials and Methods: The current retrospective descriptive study was done in the Department of Pathology, Shyam Shah Medical College, Rewa, M.P. A total of 57 FNAC slides were retrieved, re-examined, and re-classified according to the Milan system.
Results: In the present study, a total of 57 cases of salivary gland lesions were included and categorized under the Milan system of salivary gland cytology. 5.3% of the smears in our study were non-diagnostic (Category I). The most common category was IVa comprising benign neoplastic lesions with 36.8%. Non-neoplastic lesions (Category II) were seen in 24.6% cases, whereas 14% of the lesions belonged to category IVb (suspicious for malignancy). Malignant lesions (Category VI) comprised 8.8% of all the cases.
Conclusion: The most common and least common category of salivary gland lesion was Category IVa and Category IVb, respectively. The adoption of Milan classification system for reporting salivary gland FNAC is a critical step in categorizing these lesions for risk stratification and enhancing the communication among clinicians and pathologists, the ultimate result being improved patient care and management.

Authors: Mukherjee Joydeep , Goyal Sheetal , Arshad Faheem , Nashi Saraswati , Srijithesh PR  , Kulkarni Girish Baburao , Alladi Suvarna
Published: August 2022

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a clinical condition characterized by a myriad of psychiatric symptoms, abnormal movements, autonomic instability, seizures, and encephalopathy. Coronavirus disease-19 (COVID-19) infection is infrequently present with altered mental status. As the days of the COVID-19 pandemic pass, more and more awareness of its different types of immunological reactions are unveiled. A wide spectrum of clinical, pathological, and radiological manifestations has been reported. However, there have only been a few cases where anti-NMDAR antibodies have been found in people who have COVID-19. Herein, we reported two cases with simultaneous anti-NMDAR antibody and COVID-19 infection detection. Both cases clinically responded after treatment with an immunomodulator, showing significant improvement, and were discharged in a conscious and ambulatory state. Autoimmune encephalitis should be thought about if there are neurological symptoms associated with SARS-CoV-2 infection, and immunomodulators should be given to such patients.
Effect of single bolus dose of intravenous magnesium sulfate in attenuating hemodynamic stress response to laryngoscopy and nasotracheal intubation in maxillofacial surgeries
Authors: Parul Jain  , Aakansha Bikrol  , Arora KK  , Mohan Nema
Published: August 2022

Background: Nasotracheal intubation alters respiratory and cardiovascular physiology by reflex response mediated by both sympathetic and parasympathetic nervous systems and by the physical presence of the nasotracheal tube. Hypertension and tachycardia are the most common responses to intubation mediated by sympathetic efferent through cardio accelerator nerve and sympathetic chain ganglia. MgSO4 inhibits catecholamine release from adrenergic nerve endings and adrenal medulla resulting in attenuation of stress response.
Aims and Objectives: In this study, we observed the effects of MgSO4 on the hemodynamic stress response.
Materials and Methods: This prospective randomized controlled study was conducted on 60 patients after approval of the Institutional Ethics and Scientific Review committee over the period of 1 year. They were divided into two groups, Group M (MgSO4 group) received 40 mg/kg of intravenous magnesium sulfate in 100 ml normal saline and Group C (control group) received normal saline 10 min before induction. Hemodynamic parameters (HR, SBP, DBP, and MAP) were recorded at baseline, just before induction and at 1, 3, 5, 10, 15, and 30 min after intubation and every 15 min till the end of surgery.
Results: After conducting this study, we observed that heart rates at 1, 3, 5, and 10 were significantly lower in the M group as compared to the C group (P<0.05). Systolic, diastolic, and mean blood pressure were also reduced significantly in the M group as compared to the C group (P<0.05).
Conclusion: Magnesium sulfate when used at the dose of 40 mg/kg attenuates the hemodynamic stress response during laryngoscopy and nasotracheal intubation.
Association of insertion/deletion polymorphism of angiotensin converting enzyme gene with metabolic components of polycystic ovary syndrome
Authors: Susmita Banerjee  , Anindya Dasgupta  , Suparna Roy
Published: August 2022

Background: Polycystic ovary syndrome (PCOS) has taken the prime position as an endocrine disease in women of reproductive age and is estimated to affect 2.2–22.5% worldwide and in Indian women it ranges from 9% to 12%. The primary defects that cause PCOS still remains unknown. A lot of genetic factors not excluding polymorphisms and mutations of multiple genes have been linked with PCOS, exact mechanisms which might be the cause of PCOS are yet unknown. Angiotensin converting enzyme (ACE) and its yields are related with angiogenesis of ovarian epithelium, restoration of meiosis, steroidogenesis, and follicular growth.
Aims and Objectives: The present study was aimed to establish the association of ACE insertion/deletion (I/D) polymorphism in PCOS patients and to assess the influence of this polymorphism on the metabolic components of PCOS.
Materials and Methods: Genomic DNA was extracted from blood obtained from 100 patients with PCOS and 100 healthy controls following ethical guidelines. DNA was amplified by polymerase chain reaction (PCR) using I/D distinct allele primers. PCR products were assessed after being exposed to gel electrophoresis. Results were analyzed in respect to biochemical parameters.
Results: The allelic frequency and genotypic distribution of the ACE gene polymorphism is associated with PCOS in women. The concentrations of testosterones as well as luteinizing hormone/follicle stimulating hormone ratio among the distinct genotypes were significantly different. The presence of “D” allele in a population more likely to be associated with formation of polycystic ovary and hyperandrogenism was observed.
Conclusion: The data suggest that ACE I/D polymorphism and PCOS pathology are unassociated. However, aggravation of clinical symptoms of PCOS can be linked to the steroidogenesis which, in turn, is associated with the polymorphism.

Published: August 2022

Background: ST-elevation myocardial infarction (MI) in very young patients has devastating consequences and causes a huge loss to the economy and productivity. However, data regarding demographic, clinical, and angiographic profile of this population are lacking in India as also in the western literature and characteristics of presentation with acute MI (AMI) in very young patients who have been inadequately studied.
Aims and Objectives: The aims of this study were to assess the demographic, clinical, echocardiographic, and angiographic profile and risk factor pattern of patients with acute coronary symptoms at our tertiary healthcare providing hospital in Northern Maharashtra.
Materials and Methods: It was a descriptive comparative study with longitudinal design that was carried out from January 2021 to December 2021 (1 year) in the emergency room and out-patient department of our tertiary healthcare providing hospital in Northern Maharashtra, conducted among 206 consecutive patients aged ≥18 years suspected to have AMI.
Results: Among examinations and diagnostic workup, majority of the study subjects were diagnosed as ST elevation acute coronary syndromes (ACSs) (76.69%), out of which majority had anterior wall myocardial infarction (AWMI) (45.63%), followed by inferior wall MI (26.7%), lateral wall MI (4.37%). About 23.3% study subjects had non-ST elevation types of ACSs.
Conclusions: The conventional risk factors are highly prevalent even among young patients with coronary artery disease. Despite all the recent advances, delayed presentation in ACS is unfortunately widespread. AWMI is more common, most of the patients have a single-vessel disease, and in-hospital mortality is low in this young population.

Published: August 2022

Background: Medical knowledge is advancing at a rapid pace in a world, where technological evolution is at an all-time high. However, the health-care system falls well short of acceptable standards when it comes to meeting patient demands. Our medical environment, on the other hand, requires conscious revamping to increase healthcare quality. Traditional training approaches are significantly lacking in this era of value-based medicine, which prioritizes quality measurement and provider proficiency. Competency-based medical education (CBME), with its emphasis on individual, programmatic and institutional outcomes, has the ability to realign medical education with this social expectation. However, CBME implementation, on the other hand, is fraught with many challenges.
Aim and Objectives: The aim and objective of this article is to study the challenges in implementation of “foundation course (FC)” ofnewly launch CBME in Indian settings.
Materials and Methods: The study was conducted in a tertiary care center in the specialty of advanced course in Research Methodology. This was an observational study with records of 180 participants in 2019–2020 year. The average age of group was 13–50 years.
Results: One hundred and forty students and 40 teachers from various Medical Colleges had participated in the study. Around 70% participants had rated positive for the implementation of FC, while around 17% rated below average for the implementation of FC. Classes on Communication and Language (52.2%) and Computer and IT (45%) could not be taken was pointed out by the students. 35% of the students and 22.5% of the teachers pointed out that existing infrastructure is not sufficient for implementation of CBME. About 12.5% students express the concern that less study material is available on new CBME and topics included in the FC. Around 40% of the students and 17.5% of the teachers had express their concerned about time management during FC.
Conclusion: The education community has begun to address the difficulties associated with implementing of CBME. Models and guidance are available to inform implementation strategies across the educational continuum, with a focus on the more efficient use of resources and technology, as well as the use of milestones and entrustable professional activities-based frameworks.

Authors: Sharma Ashutosh , Gupta Vinita , Sharma Anita , Sharma Saurabh
Published: August 2022

Background: Vaccination against COVID-19 is necessary to reach herd immunity and essential for mitigating the spread. To establish herd immunity, the immunity generated by natural infection or vaccination must prevent onward transmission, not just clinical disease. However, several studies have shown that achieving herd immunity through natural infection might be difficult.
Aims and Objectives: The aim of the study is to enquire about parental acceptability for COVID-19 vaccination for their children, factors affecting acceptability, perceptions for pediatric COVID-19 vaccines.
Materials and Methods: We conducted an online questionnaire survey in mode of Google form which was distributed through social media platforms to parents/guardians of children below 17 years of age in months of November and December 2021. The questionnaire had various sections: Socio demographic characteristics, family members and medical history, COVID-19-related history, attitudes toward COVID-19, attitudes toward COVID-19 vaccines, and acceptance of COVID-19 vaccination for their children.
Results: The most of the parents (71.77%) were ready to vaccinate their child. Graduated parents were showing maximum acceptance. Variables related to maximum vaccine acceptance include English medium of education, higher income, COVID-19-positive member in family, vaccinated parents/guardians, and vigilant parents/guardians about child COVID vaccination. In case of side effects, 68.05% of responders agreed to follow the professional advice of personal doctor/vaccinator. About 35% of respondents want government to roll out vaccination in a phased manner. About 69% responders are in favor of making hospitals and schools as COVID-19 vaccination center for children.
Conclusion: The study found high multifactorial acceptability for pediatric COVID-19 vaccination which should be rolled out in phased manner.

Authors: Dharmendra Harjani  , Manisha Bagdi  , Nikita Bagdi Kapoor
Published: August 2022

Background: Hyperbaric bupivacaine (0.5%) is usually effective for spinal anesthesia and is being increasingly used in cases of patients undergoing lower segment cesarean section under neuraxial block. Addition of fentanyl to local anesthetic drugs such as bupivacaine and ropivacaine is associated with reduced doses of local anesthetic agents thereby decreasing side-effects of local anesthetic drugs.
Aims and Objectives: The objectives of the study are as follows: (1) To compare the efficacy of with hyperbaric bupivacaine with fentanyl and hyperbaric ropivacaine with fentanyl in patients undergoing cesarean section. (2) To compare the side effects in both the groups.
Materials and Methods: Patients were divided into two groups depending on whether they received hyperbaric bupivacaine with fentanyl (Group BF) or hyperbaric ropivacaine with fentanyl (Group RF). The onset and duration of motor as well as sensory blockade and duration of analgesia was noted. Hemodynamic parameters such as heart rate (HR) and systolic as well as diastolic pressure, respiratory rate, and SPO2 were monitored. APGAR score at 1 min and 5 min was analyzed to know immediateneonatal outcome. Post-operative pain and adverse effects were compared in both groups.
Results: Mean time for achieving highest level of sensory analgesia and duration of motor block and analgesia was found to be statistically significantly less in RF group as compared to BF group. Comparison of HR, SPO2, and respiratory rates showed that these parameters were comparable in both the groups with no statistically significant difference (P>0.05). The mean systolic and diastolic blood pressures of BF group were lower as compared to RF group and the difference was found to be statistically significant (P<0.05). At 4 h and 6 h postoperatively, the severity of pain was found to be less in RF group as compared to BF group and the difference was found to be statistically significant (P<0.05). Overall incidence of side effects was found to be comparable in both the groups (P<0.05).
Conclusion: Hyperbaric ropivacaine with fentanyl is a better alternative to hyperbaric bupivacaine with fentanyl in ASA II patients undergoing cesarean section.

Flat feet: methods of prevention and treatment
Authors: Livak P. , Korzhenko I. , Gunko T.
Published: August 2022

In this paper, the authors investigated methods for the prevention and treatment of flat feet. It was found that the problem under consideration was and remains relevant, despite the scientific progress and great success in the medical industry over the past decades. The growth of diseases is facilitated by the frivolous attitude of people to this pathology, because few people think about the scale of the problem. It has been confirmed that flat feet negatively affects not only the musculoskeletal system, but also other organ systems and the state of the body as a whole. It has also been found that the presence of flat feet can indicate a person's overall health. Today, the problem of providing assistance to adults and children with impaired foot function remains relevant and significant. Three main factors take part in the development of this disease: changes in the general physical condition, a violation in the distribution of physical activity on the musculoskeletal system, and an innate tendency. An analysis of scientific literature has shown that today the rehabilitation system for children with orthopedic pathology provides for the use of various means and methods of kinesiotherapy, where a special place is given to gymnastic and sports-applied exercises aimed at strengthening the muscles that form the arch of the foot. It was revealed that the basis of most of the diagnosed cases of flat feet is a weak tone of the muscular skeleton of the lower leg and foot, as well as excessive load on the legs caused by a long stay in an upright position. The author provided an optimal definition of the concept of flat feet, described its types and forms, named the main causes and symptoms, considered methods of prevention, treatment and correction.

Authors: Slukhenska R. , Hauriak O. , Yerokhova A. , Lytvynyuk N.
Published: August 2022

The article analyzes the important topic of stress, considers possible ways to prevent stressful situations with the help of physical exercises. The world and Ukraine in particular survived two difficult years of the pandemic with all possible bans, isolations, distance learning at all levels of the educational process. Currently, Ukraine is in an extremely difficult state of active Russian war against our country. This gave rise to new realities with limitations in education, staying in shelters, evacuation, etc. As a result of all these factors, stamina, which is very necessary for studying, even if it is done online, can decrease. Various means can help in such a difficult situation, the most effective of which are physical exercises. The purpose of the study is to define the concept of "stress" as a phenomenon of the reality of modern man, which affects the health of students of higher education institutions of our country; determination of possible ways to strengthen stress resistance through physical exertion. Distance learning, fear of war, worries for one's life as new realities of Ukrainian students have further deepened the already rather difficult student life. Physical activity is the best way to relieve psycho-emotional stress, overcome stress, and prevent diseases. Physical exercises help improve mood, gain a sense of confidence, bring the functional state of the body to an optimal level. The authors recommend students, under the conditions of distance learning, stay at home, in shelter, to prevent panic attacks and stress, breathing exercises, a set of physical exercises for different muscle groups, yoga, Pilates, etc. Conclusions were made that physical culture has an extremely favorable effect on the health of students, both physically and psychologically and mentally. However, many students take their health too lightly and neglect to perform complex exercises in physical education classes. Therefore, physical education teachers need to involve students in active sports in order to prevent the negative consequences of stress in their lives.

Published: August 2022

The purpose of research: to substantiate regional trends in the sale of agricultural machinery by analyzing the current state of the agricultural machinery market over the past three years. Research methods: analysis of sales of agricultural machinery based on information and results of analytical research provided by the regional site for the sale of machinery. The site for the sale of agricultural machinery in Kyiv region with a share of about 30% of the market in this region was taken for analysis. Research results. The research was conducted for the last three years (2020-2022. During 2020-2021, the following results were obtained, in particular: - tractors - an increase of about 50 %; - combines - a decrease of 15 %; - sprayers - reduction by 5 %; - seeders - an increase of 30 %; - tillage equipment - a decrease of 5 %; - storage bunkers and trailers - an increase of 35 %. During the 1st half of 2022, sales of all types of equipment decreased from 50 to 100 % compared to 2021. Conclusion. The market of agricultural machinery in Ukraine developed rapidly until 2022 and despite the peak of the coronavirus pandemic (COVID-19) in 2021 in Ukraine, the market of agricultural machinery continued to grow significantly sales of machinery for various groups of machines. With the onset of a full-scale Russian invasion, Ukraine's economy declined significantly, which also affected the agricultural machinery market. Sales in some groups of machines fell to 0. Only some types of machines, such as tractors from 20 to 135 hp, and tillage equipment (3-5 plows and harrows) had better result than other equipment. Most of the equipment sold in 2022 was domestic (sprayers, plows 3-5 housings, harrows with a width of 2-3 meters), except for tractors where in the above segment significantly added and lead Chinese manufacturers, displacing other manufacturers. The novelty of the article is for the first-time comparative sales of agricultural machinery in three years during the peak of the pandemic and war, and the ratio was different for different types of equipment and the ratio for the share of imported and domestic equipment for different groups of machines. Key words: agricultural machinery, machinery market, trends of agricultural machinery.

Purpose: to establish the quantitative dependences of gas emissions from the forged coal seam outside the operated areas on the degree of development of treatment works in the mine field. Methodology: the method provides for a comparative analysis of experimental data obtained during the development of several benches in the wing of the minefield. Results: the theoretical model of formation of zones of possible gas evolution from the forged coal seam outside the operated excavation sections at discrete increase of the produced space of the mine field wing by the length of the spent lava is considered. The maximum gas emission both on the excavation site and outside it is associated with the subsidence of the main roof as the development of treatment works and the removal of the treatment face from the split work. Activation of the shift of the counterfeit coal seam outside the excavation section causes an intensive increase in gas evolution, which can significantly exceed its release within the operated excavation section. Such circumstances, to a large extent, affect the safety of mining operations and indicate the need to improve the regulatory framework for the forecast of gas emissions in coal mines. Scientific novelty: statistical processing of experimental data allowed establishing the dependence of the level of gas emissions in mine workings and degassing wells simultaneously from three main factors – coal production and the degree of development of treatment works at the excavation site and within the minefield wing. Practical value: the analysis of long-term experimental results of observations of gas evolution from the forged coal-bearing stratum within the exploited sites and outside them is carried out. With sufficient development of treatment works in the wing of the mine field, the gas emissions outside the operated excavation site can significantly exceed the gas emissions in the site workings and degassing wells.

Purpose: A liquid material based on commercially available paints and fine iron ore concentrate has been created. With a filler content of 60-70 %, the coefficients of shielding of the electric field of industrial frequency is 2,6-9,1; magnetic field of industrial frequency is 4,5-6,2; electromagnetic field of ultrahigh frequency is 4,4-8,5. At the same time, the reflection coefficients of electromagnetic waves are at least twice lower than those of metal screens. Method: A calculation tool is provided for converting the weight content into the volume content of the shielding filler. This makes it possible to apply the Lorentz and Maxwell-Garnett ratios to predict the electrical and magnetic properties of metal dielectrics. To determine the reliability of adhesion of the obtained mixtures with the application surfaces, the study of the chemical and colloidal properties of the mixtures for application on gypsum board has been performed. Scientific novelty: It is established that the reduction of surface tension, surface wetting angle, work of adhesion, cohesion and wetting forces, spreading coefficient are within the limits that ensure the reliability and durability of adhesion of the material to surfaces. Results: It is shown that the reduction of the protective properties on the water-dispersion carrier is due to the oxidation of the filler. Liquid compositions are made on the basis of a number of paints and varnishes and iron ore concentrates, which can cover large surfaces in various shapes and configurations. Practical significance: In order to use the obtained mixtures in the fields of ensuring the electromagnetic compatibility of electrical and electronic equipment, it is necessary to increase the protective properties. This is possible by increasing the concentration of the shielding filler or increasing the specific conductivity of materials in the solid state by adding to the liquid mixture of fine material with high conductivity.

Purpose. Determining the impact of the incidence of cadets and students on professional activities. Methods. The materials presented in the article are the result of sociological, hygienic and physiological research to assess the professional activities of cadets and students, their ability to work, functional status, physical development and health during training, as well as analysis of morbidity of conscripts and cadets and students. to medical and preventive institutions of SES. Results. As a result, the following was created: an algorithm for assessing a healthy lifestyle; a set of exercises to prevent visual fatigue; a set of physical exercises to relieve fatigue from extra-static stress; daytime memo; nutrition factors have been identified, long-term imbalance of which contributes to the development of diseases. Scientific novelty. The scientific substantiation of professional training and measures for the prevention of diseases of cadets and students of higher educational institutions of SES of Ukraine. Practical significance. The state of morbidity of cadets and students is analyzed, and the influence of morbidity on their professional activity is determined. Currently, there is a significant deterioration in the health of cadets and students, and the attention of the medical community and school leaders to the cadet student problem has decreased slightly, and therefore requires state support for the health care system of cadets and students. A comparative study of the health of cadets and students of different universities, despite conflicting views, showed that when entering the university cadets and students are forced to adapt to a set of new factors specific to higher educational establishments of the State Emergency Service. The health of cadet youth is the most urgent task for society and the state, in connection with which state support for the health care system of cadets and students is needed. Increasing requirements for the level of training, ever-increasing intensification of the educational process require increased attention to the health of cadets and students.

Purpose. To determine methodological approaches to the integrated assessment of accidents and hazards of coal mining processes, which allow taking into account the mining and geological conditions of coal mining at a particular mining enterprise. Methods. Analytical methods, methods of probability theory, statistical processing of accidents at coal mines of Ukraine and methods of economic and mathematical modelling are used in the work. Results. Methodological bases for integrated assessment of hazards and harmfulness of production taking into account mining and geological conditions of coal mining are developed. It is shown that ambiguity of existing solutions both in terms of theoretical and methodological approaches, and in their practical use in coal mining enterprises, can lead to inefficient use of funds in the implementation of measures to improve working conditions. It is shown that the occurrence of accidents and hazards caused by hazardous production factors is probabilistic, so the economic assessment of these phenomena should be unified and take into account the expected economic losses in accidents and hazards and the probabilistic nature of these phenomena. Scientific novelty. For the first time it was proposed to use the economic assessment of hazardous and harmful production factors typical of the process or production as an integral assessment of accident rate, measure of hazardousness and harmfulness of a technological process or production. Practical value. The ambiguity of existing solutions both in terms of theoretical and methodological approaches, and in their practical use in coal mining enterprises, can lead to inefficient use of funds in the implementation of measures to improve working conditions. Availability of an integrated assessment of hazardous and harmful phenomena of coal mining allows taking more reasonable decisions aimed at preserving and developing the potential of the coal industry, as well as selection and justification of decisions on design and construction of new energy facilities taking into account social and economic aspects

Purpose. Improving the efficiency and safety of mining operations in the process of preparatory-rifled risers, through the use of rational technological schemes of borehole hydraulic technology. Methods. Analysis of literary sources, design documentation and practice of developing mineral deposits by underground method. Designing a technological scheme for borehole hydraulic technology for preparatory-rifled risers. Technical and economic comparison of the developed technological schemes for conducting preparatory-rifled risers. Results. The results of the study were proposals for improving and increasing the efficiency of preparatory-rifled risers in the process of underground mining of rich iron ore deposits by using safe technological schemes of borehole hydraulic technology. The main areas of mining and geological conditions for the rational use of specific technologies for risers are determined. Scientific novelty. The dependences of the cost of carrying out 1 m3 of preparatory-rifled riser in different ways on its length are obtained. It has been established that for the effective destruction of low-strength martite ores by hydraulic monitors, the dynamic pressure of water jets should be 0.1–0.2 of the uniaxial compression strength of the massif. Practical implication. A technological scheme has been developed for conducting preparatory-rifled risers using borehole hydraulic technology, which allows for low-operation, flow and safety of mining operations, flexibility in controlling the concentration and volume of work, good compatibility with traditional mining technologies, as well as preliminary enrichment in the converter or open-hearth production of high-quality steel grades. Efficiency is ensured by the simplification of tunneling technology, high penetration rate, energy and material savings.
