Pyoderma is a common acute superficial bacterial skin infection which is highly contagious. In the great majority of cases, pyoderma is caused by , , or both. The present study was carried out to determine the prevalence and antibiotic susceptibility of isolated from pyoderma in Dr. VRK Women’s Teaching hospital.

Swabs or pus samples were collected from 250 patients attending Dermatology, outpatient department (OPD) of Dr. VRK Women’s Teaching hospital. Samples were inoculated onto 5% sheep blood agar plates and incubated for 24 h at 37°C in a candle jar. BHS isolates were phenotypically identified by standard microbiological techniques, all the isolates presumptively identified as BHS were tested for Bacitracin susceptibility. Presumptive identification of a strain as a Group A Streptococcus (GAS) was also made by PYRase test. Presumptively identified GAS isolates were serogrouped by Lancefield grouping using a commercially available latex agglutination test. isolates were subjected to antimicrobial susceptibility testing by Kirby-Bauer disc diffusion method.

BHS were isolated from 30% of samples. Prevalence of BHS was more among 0-10 years age group (38%). BHS were isolated more frequently from males (38.8%). were isolated from 52 (20.8%) samples. All 52 isolates were found to be susceptible to Penicillin G, amoxicillin, ceftriaxone, azithromycin and vancomycin. Erythromycin and clindamycin showed good activity with sensitivity rates of 92.3% & 96.1%, respectively. Resistance to tetracycline (59.6%) and chloramphenicol (23.1%) was commonly seen in .

Authors: Rati Ruchi , Singhal Anshu , Jaggi Namita
Published: December 2021

To evaluate the sensitivity and specificity of C-Reactive protein as a single diagnostic inflammatory biomarker of neonatal sepsis in association with the blood culture.

In this study, we retrospectively reviewed the medical records of 330 neonates at a tertiary care hospital at Gurugram from Jan, 2015 to Dec, 2020. The study population included neonates <1month age. Neonates meeting the IPSC criteria (Sepsis 2.0)1 and with a positive culture were considered as neonates with proven sepsis. Neonates with congenital malformations and congenital infections associated with TORCH complex were excluded from the study.

Of the 330 neonates screened for sepsis, 32 (10%) had a positive blood culture with raised CRP in 69 (21%) cases. Among the 32 cases with positive blood culture, CRP identified 29 cases. The sensitivity, specificity, positive predictive value, negative predictive values of CRP were 90.6%, 86.5%, 42% and 99% respectively. The area under the curve (AUC) for the CRP ROC analysis was 0.83 with sensitivity of 90.6% and specificity of 91.6% which showed CRP usefulness as the diagnostic inflammatory biomarker of neonatal sepsis.

Prematurity (53%) in neonates was the most common risk factor associated with neonatal sepsis. Klebsiella pneumoniae 11 (34%) was the most common pathogen isolated with 73% susceptibility to Ciprofloxacin.

C-Reactive protein was found to have a high diagnostic value in terms of sensitivity of 90.6% and specificity of 91.6% when 0.83 is used as a cut off point for diagnosis of neonatal sepsis. Therefore, CRP could be used as diagnostic inflammatory biomarker in resource poor settings.

Published: December 2021

Teachers in schools, colleges, and universities have utilized Information and Communication Technology (ICT) based learning and teaching in the present COVID-19 pandemic situation. Teachers, students, and all other stakeholders have been stressed as a result of this abrupt paradigm shift in education. In recent years, teaching has become a difficult job (Saras, 2018), Instructors are expected to quickly adapt and incorporate technological innovations into their teaching while also participating in administrative and other academic activities, all of which contribute to occupational stress among teachers. Competition has crept into the education industry in this dynamic climate. Faculty today serves in a variety of positions in addition to instructing students, such as mentor, coach, consultant, administrator, researcher, and so on. He or she is required to devote more time and effort to the institutions to meet the demands of an ever-changing academic environment. This study attempted to study the influence of personal variables like gender, course and tenure on technostress. The results found that the personal characteristics had no significant impact on technostress in a sample of 84technical and non-technical faculty members. Further, technostress did not show to have any impact on job satisfaction and organisational commitment; indicating a need for a more comprehensive further study.

Definiowanie prawa kanonicznego
Authors: Gałkowski Tomasz
Published: December 2021

Punktem odniesienia dla przeprowadzonych rozważań są określenia prawa kanonicznego, które zostały zawarte w czterech polskich publikacjach o charakterze encyklopedycznym. Trzy z nich dotyczą prawa kanonicznego, a jedna została poświęcona prawu. W niej również zostało zawarte hasło „prawo kanoniczne”. Autor prezentuje poszczególne omówienia zagadnienia prawa kanonicznego koncentrując swoją uwagę wokół rozumienia i określania prawa kanonicznego. Wskazuje na różnice w podejściu do zagadnienia pomiędzy prawnikami a kanonistami, w ujęciu których prawo kanoniczne posiada swoje teologiczne implikacje. Dostrzega również istniejące różnice w określeniu prawa kanonicznego, na które znaczny wpływ posiadają orientacje uprawiania kanonistyki przez autorów poszczególnych opracowań. Wysuwa wniosek, że wieloaspektowe podejście do badań nad prawem kanonicznym powinno w punkcie wyjścia mieć jasno określony przedmiot naukowych badań i rozstrzygnięć. W tym kontekście zastanawia się nad możliwością podania definicji prawa kanonicznego w jej klasycznym rozumieniu. Skłania się ku stwierdzeniu takiej niemożliwości. W zamian zwraca uwagę na konieczność wyodrębnienia tych elementów kościelnej struktury i stosunków społecznych, dzięki którym istnieje możliwość określenia prawa kanonicznego.
Biritualism in the Practice of the Czech Church
Authors: Menke Monika
Published: December 2021

Both codes of canon law state the duty of bishops to care for all believers in their territory. This applies not only to the faithful of their Church, but also to the faithful of another Church sui iuris (in the case of the Czech Republic, especially the Greek Catholic Church). For pastoral help as well as support and revival of their rite, it can be in the field of liturgical help, where the priest of one ceremony receives from the Holy See the so-called faculty of biritualism. The article describes the situation in the Czech Republic, moreover complicated by the lack of priests of both ceremonies and the fact that in times of imprisonment before 1989 there were secret ordinations of married men with the Faculty of Biritualism. After the situation was relaxed, these priests were involved in the life of the Church mainly within the Greek Catholic exarchate.

Causal Relationships of Readability Risks in Construction Contracts
Authors: KOC Kerim , GURGUN Asli Pelin
Published: December 2021

Issues related to readability risks in contracts could exacerbate conflict, claim and dispute occurrences in construction projects. Determination of root causes of readability risks by defining casual relationships in construction contracts is essential to improve contract documentation and enable successful risk management. This paper aims to differentiate net causes from net effect factors of readability risks in construction contracts. Most significant readability risks in construction contracts were analyzed using fuzzy decision-making trial and evaluation laboratory (DEMATEL) method, which is known for its wide implementation in similar problems. Root cause degree (RCD) diagram was drawn to illustrate the differentiation of these factors by adopting maximum mean de-entropy (MMDE) algorithm. Analysis results indicated that poor grammar use, legal terminology, visual representation, and negative language were the major underlying cause factors; while lengthy document, use of abbreviations, scope complexity, controversial uses, repetitions, and ambiguous words were the net effect factors. The results are expected to improve readability of contract documents, which would contribute to more effective risk management and better allocation of project resources.
“Clinical Profile & Prognostic Factors In Patients with Sudden Sensorineural Hearing Loss”
Authors: Hossen Md. Feroz , Choudhury Mahbubul Alam
Published: December 2021

Introduction: Idiopathic sudden sensorineural hearing loss (ISSNHL) is an emergency disease requiring immediate diagnosis and treatment. The incidence of ISSNHL in the Western countries’ population was estimated to 5–20 per 100,000 inhabitants. The etiology of ISSNHL remains unknown. Its pathogenesis is most often suggested to be due to a disturbed microcirculation and infection.

Objective: To study the clinical profile & prognostic factors in patients with sudden sensorineural hearing loss.

Material and Methods: A retrospective study was carried out from patients of sudden sensineural hearing loss (SSNHL) presenting to ENT Department ofNorthern Private Medical College, Rangpur, Bangladesh from January to June-2020. All patients were given intravenous steroids as treatment modality for 14 days and pure tone audiogram was done every 3 days during hospital admission. It was followed by oral steroids in tapering dose for further 14 days. After 1 month, audiogram was done again. After 1 month if hearing threshold was decreased by more than 50% of presenting one, then it was labeled as improved.

Results:Total 51 patients (55ears) with age ranging from 6-70 years (average-38.5 years) were included. Three fourth were male. Presentation was 1-14days after onset of hearing loss (average- 3.7days) with pure tone audiogram (PTA) of 38-117dB (average 83.1dB). The flat audiogram (62.3%) was most common type. Smoking was present in 14 patients and tinnitus in 30 ears. Hemoglobin ranged from 7.3-18.7gm %( average- 15.3gm/dl). PTA post treatment was 8-73dB (average- 56dB). Average age of improved patient was 39.8years which was lower than non-improved patients (42.3years). In improved patients, average PTA at presentation was 77.9dB while it was 86.6dB in non-improved patients.

Conclusion: Our study demonstrates that the age distribution and clinical characteristics of ISSNHL patients vary according to levels of hearing loss. Moreover, ISSNHL patients with vertigo tend to sufer from a more severe hearing loss. Further studies are needed to obtain better knowledge about the etiopathogenesis of SSNHL.  SSNHL is more commonly seen in male patients with polycythaemia and is commonly presented in winter season and is frequently associated with tinnitus. Young age and lower audiogram threshold at presentation favor prognosis.

Published: December 2021

Relevance. The rapid expansion of the space of action of the relations of the «knowledge economy», the institution of intellectual property (IP) is enhanced by «digitalization», the whole economic architecture of the world is changing. The high dynamics and complexity of changes in economic systems and the world order, «knowledge circulation », complicate effective adaptation and constructive participation in these processes. The world is faced with the need to assess the cultural, historical and strategic consequences of all the effects of the institutionalization of IP relations. Methods. The article uses a systemic, cultural and historical analysis, based on global political economy and historical («old») institutionalism. The initial formulation of questions in this area should be of a qualitative, conceptual nature. This article uses this approach, but relying on available statistics and the possibility of a qualitative comparison of the consequences of the institutionalization of IP rights. Results. The contours of the institutionalization process, the introduction of IP relations into the global political and economic turnover, its main groups of interests and beneficiaries are considered. Qualified consequences for the economic architecture of the world and the redistribution of «world knowledge». The role of the Agreement on IP Regimes (TRIPS) in the formation of intellectual-monopoly capitalism has been determined. The effects generated by the regime of «closed science» and «closed markets» are highlighted. The mechanism of making a profit based on IP rights is considered. Signified of the importance of the advanced development of the ability to use the appropriate institutions, adequate to features of historical Russia’s cultural ecumene and civilizational characteristics of the peoples of Eurasia, and the need for a strategic transformation of personnel training systems. Discussion. The change in the economic architecture of the world and the unforeseen effects of the redistribution of «world knowledge» as a result of formation of intellectual-monopoly capitalism is an indisputable historical fact. Its consequences for the future of humanity have not been studied, uncertainty and risks are growing. It requires its awareness, consideration of the cultural and historical significance of the effects, requires the involvement of researchers from various subjects and civilizational perspectives.
Laccase-catalyzed conjugation of BSA mediated by gallic acid: Preparation, characterization, and antioxidant activity
Authors: BAT ÖZMATARA Merve , ERTAN Fatma
Published: December 2021

Laccase is one of the enzymes that catalyze the oxidation of phenolic and non-phenolic substrates and show encouraging potential as a biocatalyst in the synthesis of bioactive compounds. It is known that phenolic acids have an antioxidant effect. Bovine serum albumin (BSA) shows gelling activity, and nutraceutical binding ability but it does not show antioxidant activity. In this study, BSA which has no antioxidant activity using laccase, started to show antioxidant activity with gallic acid (GA) conjugation. The synthesized conjugates were analyzed by polyacrylamide gel electrophoresis (PAGE), ultraviolet–visible spectrophotometry (UV-Vis), and Fourier-transform infrared spectroscopy (FTIR). Radical scavenging capacity for antioxidant activity was measured. GA-functionalized-BSA displayed greatly improved 2,2'-azinobis-(3- ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 1,1-diphenyl-2- picryl-hydrazyl (DPPH) radical scavenging capacities, compared with the untreated BSA. Protein–flavonoid conjugates can improve the natural properties of proteins, being promising products to be used in medical, food and polymer fields where antioxidant ability is an essential feature.

Molecular aspects of tomato (Solanum lycopersicum) vascular wilt by Fusarium oxysporum f. sp. lycopersici and antagonism by Trichoderma spp.
Authors: Castillo-Sanmiguel Paula Andrea , Cortés-Sánchez Laura Rocío , Acero-Godoy Jovanna
Published: December 2021

Tomato plants (Solanum lycopersicum) are susceptible to the infection by diverse pathogens that cause devastating diseases such as vascular wilt, which causes great losses at the production level. The fungus Fusarium oxysporum f. sp. lycopersici (Fol) is one of the etiologic agents of this disease and its control lies in the use of synthetic chemicals which generate a negative impact in both health and the environment; thus, it is necessary to implement biological control as a healthier and more efficient alternative. The fungus Trichoderma spp. is a favorable option to be employed as a biocontroller against this pathogen thanks to its antagonist mechanisms, determined by metabolic and genetic characteristics. On the one hand, for Fol it is indispensable the activation of signaling routes such as MAPK Fmk1, MAPK Mpk1 y HOG, while Trichoderma spp. uses effectors involved in the interaction with the plant such as proteins, enzymes and secondary metabolites that also strengthen its immune response against infection, determined by both Pathogen Associated Molecular Patterns (PAMP) and effectors. Therefore, this article makes a review about the mentioned characteristics and suggests a greater application of tools and molecular markers for the management of this disease.

Authors: Morillo Puente Solbey , Ríos Hernández Iván Neftalí
Published: December 2021

This quantitative-based research determined whether the routine activity theory influences cyber victimization. To measure the dimensions of the theory, defined as exposure to a motivated offender, suitable online target, and absence of a capable guardian, a valid and reliable questionnaire was used. The cyber victimization questionnaire developed by Álvarez-García, Dobarro, and Núñez was applied to 1,285 students selected at random from schools in Colombia. Findings: 46% are identified as exposed to a motivated offender, 37.5% are suitable online targets, and 29.8% have no capable guardians. The interdependence of these three elements revealed that 3.9% of students are at risk due to their routine activities, which had a significant influence on cyber victimization. It is proposed that these findings should be considered in the design of communicative and educational policies aimed at a responsible use of technologies.

Authors: Troncoso-Espinosa Fredy Humberto , Castro-Albornoz Karen
Published: December 2021

Un revestimiento moldeado para puertas es un tablero de madera de alta densidad que es utilizado como el principal componente en la fabricación de puertas.  Para asegurar su comercialización, se debe cumplir con exigentes normas de calidad, siendo la principal norma aquella que mide la fuerza necesaria para desprender el revestimiento de la estructura de una puerta. Los ensayos de calidad son realizados cada dos horas y sus resultados son obtenidos luego de aproximadamente cinco horas. Si los resultados muestran que los revestimientos están fuera del estándar de calidad exigido, se generan pérdidas económicas debido a este tiempo de espera. Esta investigación propone el uso de minería de datos mediante técnicas de machine learning para predecir en forma continua esta medida de calidad y reducir las pérdidas económicas asociadas a la espera de los resultados. Para la aplicación de minería de datos, se creó una base de datos en base al registro histórico de las variables del proceso productivo y de los ensayos de calidad. La metodología empleada es el descubrimiento de conocimiento en bases de datos KDD (Knowledge Discovery in Databases). La aplicación de esta metodología permitió identificar las principales variables que afectan la calidad de los revestimientos y entrenar cuatro algoritmos de machine learning para predecir su calidad. Los resultados muestran que el algoritmo que mejor predice la calidad es Neural Net y permiten demostrar que la implementación del algoritmo Neural Net reducirá las pérdidas económicas asociadas a la espera de los resultados de los ensayos de calidad.

Published: December 2021

Heavy tailed distributions have a big role in studying risk data sets. Statisticians in many cases search and try to find new or relatively new statistical models to fit data sets in different fields. This article introduced a relatively new heavy-tailed statistical model by using alpha power transformation and exponentiated log-logistic distribution which called alpha power exponentiated log-logistic distribution. Its statistical properties were derived mathematically such as moments, moment generating function, quantile function, entropy, inequality curves and order statistics. Five estimation methods were introduced mathematically and the behaviour of the proposed model parameters was checked by randomly generated data sets and these estimation methods. Also, some actuarial measures were deduced mathematically such as value at risk, tail value at risk, tail variance and tail variance premium. Numerical values for these measures were performed and proved that the proposed distribution has a heavier tail than others compared models. Finally, three real data sets from different fields were used to show how these proposed models fitting these data sets than other many wells known and related models.

Authors: Helu Amal , Hani Samawi
Published: December 2021

In this article, we consider statistical inferences about the unknown parameters of the Lomax distribution basedon the Adaptive Type-II Progressive Hybrid censoring scheme, this scheme can save both the total test time and the cost induced by the failure of the units and increases the efficiency of statistical analysis. The estimation of the parameters is derived using the maximum likelihood (MLE) and the Bayesian procedures. The Bayesian estimators are obtained based on the symmetric and asymmetric loss functions. There are no explicit forms for the Bayesian estimators, therefore, we propose Lindley’s approximation method to compute the Bayesian estimators. A comparison between these estimators is provided by using extensive simulation. A real-life data example is provided to illustrate our proposed estimators.

Authors: Bibi Abdelouahab , Merahi Fateh
Published: December 2021

This paper examines the moments properties in frequency domain of the class of first order continuous-timebilinear processes (COBL(1,1) for short) with time-varying (resp. time-invariant) coefficients. So, we used theassociated evolutionary (or time-varying) transfer functions to study the structure of second-order of the process and its powers. In particular, for time-invariant case, an expression of the moments of any order are showed and the continuous-time AR (CAR) representation of COBL(1,1) is given as well as some moments properties of special cases. Based on these results we are able to estimate the unknown parameters involved in model via the so-called generalized method of moments (GMM) illustrated by a Monte Carlo study and applied to modelling two foreign exchange rates of Algerian Dinar against U.S-Dollar (USD/DZD) and against the single European currency Euro (EUR/DZD).

Authors: BOZBIYIK Osman , ÇOKER Ahmet
Published: December 2021

Aim: Colorectal cancer is among the most common malignancies and liver metastasis is developed in 50% of the patients. Hepatic resection is the most effective treatment in liver metastasis of colorectal cancer. The present study aimed to determine the factors that affect survival in patients who underwent hepatic resection in liver metastasis of colorectal cancer.
Materials and Methods: The data on patients who underwent hepatic resection due to liver metastasis of colorectal cancer in Ege University, Faculty of Medicine, General Surgery Department were retrospectively analyzed. Survival data were collected with the review of patient follow-up files. The effects of the factors pertaining to the patients on survival were determined.
Results: The mean age of the 62 participating patients was 58.08 ± 10.92 years. Total survival rate was 50.4 months (CI: 41.2-59.7). The factors that statistically significantly reduced the survival rate were determined as follows: Patient age> 65 (<65 years: 56.4 ± 5.5 months / ≥65 years: 29.3 ± 4.8 months, p = 0.007), presence of more than four lymph node metastases in the primary tumor (N0: 56.1 ± 7.9 months / N1: 56.5 ± 6.5 months / N2: 18.0 ± 3.0, p = 0.001), presence of bilobular liver metastasis (Uni-lobular: 53.4 ± 5.0 months / bilobular: 24.0 ± 4.4 months, p = 0.026), and liver resection margin closer than 2 mm (<2 mm: 28.4 ± 7.7 months / 2-9 mm: 61.1 ± 7 , 6 months, ≥10mm: 46.3 ± 5.9 months, p = 0.003). No statistically significant differences were determined in survival based on gender, location of the primary tumor, the invasion depth of the primary tumor, the time between colorectal and liver surgery, the carcinoembryonic antigen level, the metastasis diameter, the number of metastases and the extent of surgical resection.
Conclusion: In patients who underwent surgical resection for liver metastasis of colorectal cancer, age older than sixty-five years, the presence of more than four lymph nodes in the colon resection material, bilobular liver metastasis, and a surgical margin closer than 2 mm were poor prognostic factors.

The use of various scaffolds makes it possible to model the future fibrous framework of the newly formed regenerate, and also serves as a substrate for the colonization of the cellular component. The development of tissue engineering in regenerative medicine requires an understanding of more precise mechanisms of the formation of the connective frame at the site of the defect. The aim of this study was to study the morphofunctional rearrangement of the fibrous structures of the dermis of the skin of rats, in response to for the implantation of a 3D-scaffold based on polyprolactone. The study was carried out on the skin of male Wistar rats at different times after implantation of a 3D-scaffold based on polyprolactone. The biomaterial with the implantable scaffold was studied using scanning electron microscopy. As a result of the study, it was revealed that active collagenogenesis is determined around the structures of the 3D-scaffold based on polyprolactone. By the 14th day, a large number of circularly directed collagen fibers are visualized, which are the basis for further building a connective tissue capsule around the fibers. Conclusions are drawn about the effectiveness of using a 3D-scaffold based on polyprolactone. This implant can also be effective for the colonization of allogeneic cultured fibroblasts and the creation of biomedical tissue engineering products on its basis.

Aim: to compare endovascular and open revascularizing interventions in patients with neuro-ischemic form of diabetic foot in order to choose the management tactics for this category of patients, which has the best results in the near and long term. Materials and Methods: The study involved 85 patients with critical lower limb ischemia of atherosclerotic genesis and diabetes mellitus, hospitalized for revascularization in a specialized department. The study participants were divided into two groups: the first group included 38 patients who underwent endovasal revascularization of the affected arterial segment, the second - 47 patients who underwent femoropoplitealautovenous bypass grafting below the knee joint. Results: during the dynamic observation of patients, it was found that the number of reoperations on a previously revascularized limb was significantly higher in the group of endovascular interventions than in the group of open reconstructions: 19 (50 %) and 7 (14,9 %), respectively. In the long-term period, three patients of the second group underwent amputation at the hip level, in contrast to the patients of the first group, in which not a single case of amputation was recorded at the indicated level (p = 0,05). Conclusions: for patients with diabetes mellitus and critical lower limb ischemia, endovasal revascularization can be recommended as the most preferable due to the existing features of arterial lesions, the possibility of repeated surgical intervention and preservation of the limb and its support ability.

Correctly selected tactics of surgical intervention on the trunks of peripheral nerves largely determines the duration of the rehabilitation period and full restoration of the function of the nerve trunk. At the same time, it is necessary to know all the topographic, anatomical and morphometric features of the peripheral nerves and the surrounding connective tissue sheaths. Considering the fact that the laboratory rat is the most optimal experimental animal, the study of the morphometric and topographic features of its peripheral nerves of the extremities, in particular the sciatic nerve, is the most in demand at the present time. The aim of this work was to study the features of the topography and morphometry of the sciatic nerve of the rat. The study was carried out on laboratory animals male Wistar rats, which were dissected the sciatic nerve on both limbs and carried out morphometry according to the author's method. As a result of the study, it was revealed that the sciatic nerve of the rat can be both a continuation of the lumbosacral trunk and separate from the sacral plexus. Independent detachment of two large trunks enclosed in one common fascial sheath, which in the lower third of the thigh diverged into separate - the common peroneal and tibial nerves, was observed in 20 % of the studied individuals. Morphometric examination revealed the prevalence of the sciatic nerve trunk thickness on the left limb. The revealed topographic and morphological differences in the organization of the sciatic nerve on the right and left extremities must be taken into account in experimental studies when developing approaches to the nerve trunk and carrying out, in the area of the surrounding connective tissue sheaths, various therapeutic manipulations.

Currently, the most common, safe and comfortable operation for the correction of myopia is the technology of small-incision lenticule extraction. The short period of rehabilitation and the stability of the result of this technology is due to minimal damage of the collagen fibers, activation and degenerative changes in keratocytes, which in most cases are reversible.

Odontoreparation is fundamental to ensure the functional efficiency, high aesthetics and durability of fixed prostheses. At present, with fixed prosthetics of defects in hard tissues of teeth and dentition, various types of artificial crowns are widely used [1, 2]. Purpose of the study: to determine the angular deviations of the vertical surfaces of molars, prepared by students of the 3rd year. Based on the data obtained, calculate the average value for the group and identify which surfaces of the stump are most prone to errors during odontopreparation. Materials and methods. Frasaco® phantom teeth (mandibular molars) were used as research materials. Preparation for metal-ceramic crowns was carried out according to the traditional method by thirteen third-year students of the Samara State Medical University of the Ministry of Health of Russia. In this work, 6° was taken as the optimal angle of convergence of the vertical walls (3° on each of the two opposite surfaces). During the preparation, a fissure bur d = 1,6 mm was used. Conclusion. The average time spent on preparation is quite long, which indicates an insufficient level of manual skills. The revealed phenomena of wall divergence also indicate that the preparation skills are insufficient. In addition, divergence was found mainly on the distal surface, which is explained by more difficult access and limited visibility of the prepared surface.
