Importancia de la trayectoria escolar como plataforma para la construcción de la identidad docente del profesor universitario
Authors: Rodríguez Rivera Xochiquetzal Xanat , Covarrubias-Papahiu Patricia
Published: July 2021

The importance of studying the identity of university teachers lies in their role as mediators of learning and as key elements in the professional training of new generations. In this sense, and considering that teaching identity is historically and relationally constructed in different spaces of socialization, we report the findings regarding the school trajectories of university teachers, which constitutes one of the exploration axes of an ongoing research project, whose purpose is to investigate how the teaching identity of university teachers is constructed and the way in which they perceive and mean their pedagogical practice. The school trajectory of university professors is important insofar as it reveals their dispositions towards higher education, the type of experiences they have to overcome and face as students, and the type of paths and strategies necessary to develop for an eventual identity as teachers. The qualitative biographical-narrative approach was used to obtain life stories of professors from different disciplines working in a public and a private university. The findings highlight the importance of cultural capital for career choice; student sociability among peers during high school; identification with disciplinary knowledge and knowledge of the chosen profession; experiences and opportunities for collaboration as students with university professors; distinguishing oneself as an outstanding student, and the influence of memorable professors as figures and role models.

Environmental impact assessment (EIA) is a preemptive tool used by engineers, environmental consultants and planners to avoid the most likely adverse consequences of development projects. As a planning tool, EIA should curb the harmful effects from all stages of a project lifecycle. Landslides and flash floods are the most common problems faced by Malaysians almost yearly due to rapid development, especially that involving modification of watercourses, clearing of land and projects on hill slopes. Despite such issues, existing legislation and new guidelines have been enacted by the Malaysian government and must be followed by any proposing project team before starting development projects. The Department may have accepted an EIA report of the project. Still, several developments may have neglected the guidelines, especially during construction involving earthworks and exposure of the surrounding environment, place and people to a high risk of disaster caused by mishaps and accidents. The incidence of landslides and flash floods as reported in newspapers, journals, reports and books since 1919 is explored in this study to determine the details of the losses and locations. Despite the enactment of the new EIA law, landslides and flash floods continue to occur. This situation justifies the need to revise the approach based on sizes and include other factors, namely, the risk indices for disaster to happen and the effectiveness of EIA in reducing disaster risks in projects.

Authors: . Surbhi , Majhi Bangali
Published: July 2021

Background: The aim of the study was to determine association of abnormal lipid profile in early second trimester (14 to 20 weeks) with development of pre-eclampsia.Methods: A prospective observational study included 260 women between 14-20 weeks of pregnancy attending a tertiary care Hospital in New Delhi. Serum lipid profile analysis was performed at the time of enrolment and cohort was followed up for occurrence of pre-eclampsia till 48 hours after delivery. Outcomes measured were difference in mean lipid levels in study (abnormal lipid profile) and control group (normal lipid profile) and accuracy of abnormal lipid profile to predict pre-eclampsia.Results: The incidence of pre-eclampsia in our study was 11.13%. The mean serum total cholesterol was significantly higher in pre-eclampsia group (199.74 mg/dl vs 171.7 mg/dl; p<0.05). The difference in mean triglyceride, HDL, VLDL and LDL levels between two groups was not significant. Total cholesterol has 44.83% sensitivity, 84.85% specificity, 27.08% PPV, 92.45% NPV with diagnostic accuracy of 80.38% in predicting pre-eclampsia (with 0.65% AUC with 95% confidence interval). While VLDL has maximum sensitivity of 68.97% while HDL has maximum specificity of 86.15% in predicting pre-eclampsia.Conclusions: Abnormal total cholesterol levels have diagnostic accuracy of 80.38% to predict pre-eclampsia and abnormal lipid profile in early second trimester is a simple, non-invasive and economical test for prediction of pre-eclampsia.
Brain Tumor Detection Based on Features Extracted and Classified Using a Low-Complexity Neural Network
Authors: Papageorgiou Vasileios
Published: July 2021

Brain tumor detection or brain tumor classification is one of the most challenging problems in modern medicine, where patients suffering from benign or malignant brain tumors are usually characterized by low life expectancy making the necessity of a punctual and accurate diagnosis mandatory. However, even today, this kind of diagnosis is based on manual classification of magnetic resonance imaging (MRI), culminating in inaccurate conclusions especially when they derive from inexperienced doctors. Hence, trusted, automatic classification schemes are essential for the reduction of humans’ death rate due to this major chronic disease. In this article, we propose an automatic classification tool, using a computationally economic convolutional neural network (CNN), for the purposes of a binary problem concerning MRI images depicting the existence or the absence of brain tumors. The proposed model is based on a dataset containing real MRI images of both classes with nearly perfect validation-testing accuracy and low computational complexity, resulting a very fast and reliable training-validation process. During our analysis we compare the diagnostic capacity of three alternative loss functions, validating the appropriateness of cross entropy function, while underlining the capability of an alternative loss function named Jensen-Shannon divergence since our model accomplished nearly excellent testing accuracy, as with cross-entropy. The multiple validation tests applied, enhancing the robustness of the produced results, render this low-complexity CNN structure as an ideal and trustworthy medical aid for the classification of small datasets.
A Hybrid Capsule Network for Pneumonia Detection Using Image Augmentation Based on Generative Adversarial Network
Authors: Firildak Kazim , Talu Muhammed Fatih
Published: July 2021

Pneumonia, featured by inflammation of the air sacs in one or both lungs, is usually detected by examining chest X-ray images. This paper probes into the classification models that can distinguish between normal and pneumonia images. As is known, trained networks like AlexNet and GoogleNet are deep network architectures, which are widely adopted to solve many classification problems. They have been adapted to the target datasets, and employed to classify new data generated through transfer learning. However, the classical architectures are not accurate enough for the diagnosis of pneumonia. Therefore, this paper designs a capsule network with high discrimination capability, and trains the network on Kaggle’s online pneumonia dataset, which contains chest X-ray images of many adults and children. The original dataset consists of 1,583 normal images, and 4,273 pneumonia images. Then, two data augmentation approaches were applied to the dataset, and their effects on classification accuracy were compared in details. The model parameters were optimized through five different experiments. The results show that the highest classification accuracy (93.91% even on small images) was achieved by the capsule network, coupled with data augmentation by generative adversarial network (GAN), using optimized parameters. This network outperformed the classical strategies.
Digital Image Denoising Techniques Based on Multi-Resolution Wavelet Domain with Spatial Filters: A Review
Authors: Ismael Ahmed Abdulmaged , Baykara Muhammet
Published: July 2021

Recently, with the explosion in the number of digital images captured every day in all life aspects, there is a growing demand for more detailed and visually attractive images. However, the images taken by current sensors are inevitably degraded by noise in various fields, such as medical, astrophysics, weather forecasting, etc., which contributes to impaired visual image quality. Therefore, work is needed to reduce noise by preserving the textural, information, and structural features of the image. So far, there are different techniques for reducing noise that various researchers have done. Each technique has its advantages and disadvantages. In this paper, a review of some significant work in the field of image denoising based on that the denoising methods is presented. These methods can be classified as wavelet domain, spatial domain, or both methods can combine to obtain the advantage them. After a brief discussion, the classification of image denoising techniques is explained. A comparative analysis of various image denoising methods is also performed to help researchers in the image denoising area. Besides, standard measurement parameters have been used to compute the results and to evaluate the performance of the used denoising techniques. This review paper aims to provide functional knowledge of image denoising methods in a nutshell for applications using images to provide ease for selecting the ideal strategy according to the necessity.

Authors: Wagle Shivali Amit , R Harikrishnan
Published: July 2021

Deep learning models are playing a vital role in classification goals that can have propitious results. In the past few years, many models are being used for this purpose of plant disease classification. This work has assisted in the process of identification and classification of a plant leaf disease. In this paper, the Tomato plant leaf images are taken from the PlantVillage Database consisting of one healthy and eight disease classes. The disease classes are selected based on the occurrence of the disease in India. The deep learning models of AlexNet, VGG16, GoogLeNet, MobileNetv2, and SqueezeNet are used in this work for the classification of Tomato plant leaf as healthy or diseased and further which disease class it belongs to. The models used here are all the pre-trained models, so transfer learning is used to fit the total number of classes that need to be classified by the network model. VGG16 model outperformed giving 99.17% accuracy compared to AlexNet, GoogLeNet, MobileNetv2, and SqueezeNet. The work concludes with the model’s validation results on the set of images captured at Krishi Vigyan Kendra Narayangaon (KVKN), India.

Published: July 2021

To a certain extent, automated fruit sorting systems reflect the degree of automated production in modern food industry, and boast a certain theoretical and application value. The previous studies mostly concentrate on the design of robot structure, and the control of robot motions. There is little report on the feature extraction of fruits in specific applications of fruit sorting. For this reason, this paper explores the target positioning and sorting strategy of fruit sorting robot based on image processing. Firstly, the authors constructed a visual sorting system for fruit sorting robot, and explained the way to recognize objects in three-dimensional (3D) scene and to reconstruct the spatial model based on sorting robot. Next, the maturity of the identified fruits was considered the prerequisite of dynamic sorting of fruit sorting robot. Finally, the program flow of the fruit sorting robot was given. The effectiveness of our strategy was verified through experiments.

Published: July 2021

Diagnosis based on chest X-rays is widely used and approved for the diagnosis of various diseases such as Pneumonia. Manually screening of theses X-ray images technician or radiologist involves expertise and time consuming. Addressing this, we propose an automated approach for the diagnosis of pneumonia by assisting doctors in spotting infected areas in the X-ray images. We propose a deep Convolutional Neural Network (CNN) model for efficiently detecting the presence of pneumonia in the X-ray images. The proposed CNN is designed with 5 convolution blocks followed by 4 fully connected layers. In order to boost the performance of the model, we incorporate batch normalization, dynamic dropout, learning rate decay, L2 regularization weight decay along with Adam optimizer and binary Cross-Entropy loss function while training the model using back propagating algorithm. The proposed model is validated on two publicly accessible benchmark datasets, and the experimental studies conducted on these datasets indicate that the proposed model is efficient. The suggested CNN architecture with specified hyper parameters allows the model to outperform several existing models by achieving accuracy of 97.73% and 91.17% respectively for binary and multi-class classification tasks of pneumonia disease.
The role of matrix metalloproteinases in pathogenesis of human bladder cancer
Authors: Wątroba Sławomir , Wiśniowski Tomasz , Bryda Jarosław , Kurzepa Jacek
Published: July 2021

Matrix metalloproteinases (MMPs) play an important role in many physiological and pathological processes, including neoplastic processes. They belong to a group of enzymes called endopeptidases and have the ability to hydrolyze all proteins in the extracellular matrix (ECM). They are produced in most connective tissue cells, macrophages, leukocytes, endothelial cells, microglial cells and in cancer cells. Neoplastic diseases are one of the main causes of death in Poland and in the world, therefore learning about the process of carcinogenesis seems to be particularly important. The process of carcinogenesis is currently widely studied and MMPs play one of the key roles in the development of cancer. They do this by regulating local tumor growth, stromal invasion, stimulating angiogenesis and metastasis formation. Bladder cancer is the 7th most common cancer in the male population and the 11th most common cancer in the world. In bladder cancer, most studies have been devoted to MMP-2 and MMP-9, that are enzymes responsible for the degradation of type IV collagen in the first place, which through the destruction of basement membranes and ECM, play an essential role in the tumor invasion process. Since bladder cancer is characterized by the ability to relapse, from the point of view of clinical practice it seems particularly important to develop a marker of early bladder tumor recurrence. MMPs detected in the urine and serum of patients with bladder cancer are potential factors that could play such a role.
Group Formation based on Students’ Learning Styles by Circular Genetic Algorithm
Authors: Sukstrienwong Anon
Published: July 2021

Student group formation plays a critical role in promoting academic learning styles. Therefore, in this study, we employed a heuristic algorithm called the circular genetic algorithm (CGA) to form balanced groups of dissimilar students in terms of personal preferred learning styles. The benefit of balancing students’ learning styles is to assist students with diverse abilities to work collaboratively. With the assistance of our developed web application, members within a group contain mixed characteristics, while all formed groups of students are similar. In addition, an empirical case study was used to verify the feasibility and effectiveness of the proposed algorithm. Corresponding results verified by the analysis of variance (ANOVA) indicate that the algorithm can optimally allocate students in an efficient way.

Authors: Mokhtari MalekAbadi Arefeh , Jafarnezhadgero Amirali
Published: July 2021

Introduction: As a person gets older, their gait patterns change and their ability to walk decreases. Orthoses are used to relieve musculoskeletal disorders, skeletal problems, disabilities, etc. Therefore, the aim of this study was to investigate the effect of orthoses on timing of lower limb muscles in the older adults during gait.
Methods: The present study was a clinical trial. 14 females (with average age of 60.50±4.40 years) and 14 males (with average age of 63.35±5.55 years) were selected with available sampling, voluntarily participated in this research. Eight electrodes were placed on the selected muscles (tibialis anterior, gastrocnemius medial, vastus medialis, vastus lateralis, biceps femoris, semitendinosus, gluteus medius, erector spinae) to record electrical activity during the gait with and without orthoses. To analyze the data SPSS software (version 16), and a repeated analysis of variance test was used. The significance levels in all tests were considered to be 0.05.
Results: The main effects of orthoses and the interaction effects of orthoses and sex for the onset of selected muscles activities did not show any significant differences (P>0.05). The effect of sex for the onset of activities in medial gastrocnemius (P=0.007), vastus medialis (P=0.002), vastus lateralis (P=0.027), semitendinosus (P=0.004), gluteus medius (P=0.030), and erector spinae (P=0.039) muscles was significant, so that the onset of muscle activity in the female group was earlier than in the male group.
Conclusion: Orthoses showed no improvement on onset of selected muscles activities, although significant differences were observed between the male and female groups.

Tarihten Günümüze Kur’an ile Yetinme Söyleminin Kritiği
Authors: ASLAN Recep
Published: July 2021

Kur’an ile yetinme söylemi/Hadisi inkâr düşüncesi, her dönemde az veya çok Müslümanların gündeminde olmuş bir meseledir. Çağımızda sünnete karşı olumsuz tavır takınan marjinal gruplar olduğu gibi, tarihi süreç içerisinde de sünneti kabul etmeyen, İslâm’ın sadece Kur’an’dan ibaret olduğunu gizli veya açıkça iddia eden “Kur’an İslâm’ı” veya “Kur’an Müslümanlığı” şeklinde birtakım isimlerle kendini nitelendiren kesimler olmuştur. Kur’an ile yetinme söyleminin birtakım çıkmazları vardır. Sadece Kur’an ile yetinme demek, Hz. Peygamber’in tebyîn görevini elinden alıp sadece tebliğ görevi ile iktifa etmek anlamına gelir. Bu söylemi dillendiren çevreler, Hz. Peygamber’in konumu ile alakalı âyetleri parçacı yaklaşımla işlemekte, Hz. Peygamber’in statüsünü adeta bir postacı durumuna indirgemektedirler. Kur’an ve sünnetten birini kabul etmemek dinin bir kısmını kabul edip diğer bir kısmını inkâr etmek anlamına gelir. Bu çalışmada, Kur’an ile yetinme söyleminin tarihi arka planına ve günümüze yansımasına ana hatlarıyla değinilecektir.
Klasik Dönem İslam Düşüncesinde Dünya Merkezli Evren Algısı ve Teolojik Nedenleri
Authors: CESUR Ertuğrul
Published: July 2021

Klasik tefsir kitaplarına yansıdığı üzere Müslüman düşüncesinde de hâkim evren resmi aslında Antik Çağ’dan modern zamanlara, dünyanın hemen her yerinde geçerli geosantrik evren modelidir. Nihayetinde Kur’an’ın asli gayesi astronomi bilgisi değil, geçerli dış dünya algısı ne olursa olsun insanların yeryüzünü ifsat etmeden bir arada yaşayabilecekleri bir toplum düzeni yönünde yaratılış gayesine matuf ilkeleri hatırlatmaktır. Bunu yaparken de dönemin dil ve kültürel gerçeklerinden hareket eder. Buna göre verili kültürün kendi iç tutarlılığı içinde bu hikmeti gözeten bir toplumsal düzen tesis edilen ilk İslam toplumda siyasal sistemin dayanağı tanrısal temsil de “halife” kavramı üzerinden topluma şamil hale gelir. Ne var ki, Hz. Peygamber sonrası siyasi ihtilaflarda tarafların kendi konumlarını dini referanslarla tahkim etmeleri, dünya merkezli bir evren fikrine ilişkin teolojik kabulleri pekiştirir.

Las funciones del Derecho concursal: tendencias actuales en el Derecho comparado
Authors: Moreno Buendía Francisco Jesús
Published: July 2021

Las crisis económicas sufridas por la mayoría de los países industrializados han removido los cimientos del Derecho concursal, especialmente en lo que atañe a sus principios y funciones elementales. En este sentido, el aumento del volumen y de la complejidad de las estructuras empresariales ha incidido notablemente en las recientes reformas del Derecho concursal, las cuales han tratado de incentivar la función conservativa de los procedimientos concursales. La tendencia actual consiste en proteger la empresa en crisis mediante su saneamiento o rehabilitación, pero este loable propósito no puede ser ajeno a un análisis económico-funcional de la solución concursal que se aplique en cada caso. 
Las crisis económicas sufridas por la mayoría de los países industrializados han removido los cimientos del Derecho concursal, especialmente en lo que atañe a sus principios y funciones elementales. En este sentido, el aumento del volumen y de la complejidad de las estructuras empresariales ha incidido notablemente en las recientes reformas del Derecho concursal, las cuales han tratado de incentivar la función conservativa de los procedimientos concursales.
El propósito de este artículo es analizar las dinámicas en la configuración de la función del Derecho concursal presentes en las recientes intervenciones legislativas llevadas a cabo por algunos países Europeos y Latinoamericanos. Para alcanzar dicho objetivo se sigue fundamentalmente un método analítico-descriptivo, a través del cual se justifica la relevancia interpretativa de la función del Derecho concursal, y se exponen las funciones tradicionales atribuidas al Derecho concursal y el protagonismo de la función conservativa presente en las últimas reformas concursales. A partir de ello, se realiza un análisis económico-funcional de esta tendencia, lo cual permite descubrir las tensiones existentes entre la función conservativa y la función solutoria de los procedimientos concursales. Desde esta perspectiva, se concluye sobre la necesidad de priorizar la finalidad solutoria de los procedimientos concursales, a pesar de la relevancia que actualmente se atribuye a la protección de la empresa en crisis mediante su saneamiento o rehabilitación.
Posthumanism and the New Ethics of Medical Practice—Epidemiology as the New Deontological Paradigm
Authors:   Resident doctor, University of Medicine and Pharmacy “Carol Davila” Bucharest, Romania, Vitan Timea
Published: July 2021

In the context of the COVID19 pandemic, during last year all public attention has been focused on Medicine. Epidemiology is no longer just one medical specialty among many others, but became the main paradigm and the unique background of medical science. The individual pacient has turned into the collective pacient. Medical policies are not centered on the pacient anymore, but on its social group. In this article I will try to show how the characteristics of medical practice changed since the pandemic began and which are the deontological implications of such changes. With a short introduction on the medical policies proposed by the WHO during the last decades, I wish to underline the recent history of medical practice and its obvious turning point occasioned by the pandemic. Once the new bioethical vantage points are set, I wonder to which extent posthumanist philosophy foresaw this new deontological paradigm. Having Rosi Braidotti`s “The Posthuman” as my starting point, I maintain that medical doctors no longer practice on a humanist background, but with a sort of commitment that goes beyond the individual. However, this is not an antihumansit pledge, because contemporary medical doctors still adhere to certain humanist principles. As it so often happens, we will be left with even more questions. If the pacient is no longer the individual, but the group of individuals, which is the nature of a symptom and how should we decipher its meaning? How would a new medical science look like if we are to build it not on a human but on a posthuman biology?
An Official Matter: Life and Death During the Sanitary Crisis. Semiotics and Philosophy in Times of Pandemic
Authors:   PhD, University of Bucharest, 90, Panduri av., 5th District, Bucharest, Romania, Hodorogea Vasile
Published: July 2021

Over a million cases of infected people, thresholds and dramatic records constantly exceeded, the voices of the State and of the civil society covering each other in search of validation, an alienated and disoriented population – this is the general picture of a Romanian society trying, on one side, to understand a global phenomenon and, on the other side, to adapt to situations, norms and regulations that has not been encountered for generations. In an effervescent social, economic and political context, the Coronavirus pandemic tests the whole society and forces the State to react, both through concrete measures (rules, restrictions) and through education and awareness campaigns. The official messages transmitted by the State, through the media and in the form of commercials, advertisements, are subject to an evolution in visual and verbal aspect, which can be questioned both in terms of philosophical theories such as utilitarianism or social contract, and from the semiotic perspective of the meanings carried by these messages. How is the "common good" found in the education and awareness campaigns for wearing protective masks and for frequent sanitation and disinfection? And if Rousseau's "common good" is not fully visible in the mask that "can save your life," is the general goal of the government campaign one of a utilitarian nature? To what extent does the promise of the presence of pleasure and the absence of pain appear, as described by John Stuart Mill, in a campaign built on "saving lives" and "protecting others"? This research advances the proposition of a perception analysis of the meanings conveyed in the television commercials from the official awareness and education campaign regarding the Coronavirus pandemic, between March 2020 and January 2021, decanted in terms of basic semiotic and philosophical concepts and theories.

Nekatera poglavja so bolj teoretske narave in preučujejo različne vidike varnosti, medtem ko so nekatera poglavja tudi produkt empiričnega raziskovanja varnostne problematike v ruralnih in urbanih lokalnih skupnostih.
Sociološki vidiki življenja in občutkov ogroženosti v ruralnih in urbanih skupnostih v Sloveniji
Authors: Bučar Ručman Aleš
Published: July 2021

Avtor postavi teoretično izhodišče in konceptualizacijo ruralnega in urbanega družbenega življenja izpelje iz tez klasičnih avtorjev (Marx, Tönnies, Durkheim, Polany, Weber). V poglavju se osredotoča na vprašanje pojmovanja in razumevanja ruralnosti, temeljne značilnosti skupnostnega življenja v slovenskih ruralnih in urbanih skupnostih ter na iskanje razlik med ruralnimi, suburbanimi in urbanimi območji. S pomočjo sekundarne analize podatkov raziskave Varnost v lokalnih skupnostih (2017) in Slovensko javno mnenje 2016/1 (Kurdija et al., 2016) prikazuje in razlaga razlike o zaznavanju varnostnih groženj med ruralnimi in urbanimi skupnostmi v Sloveniji. Zaključuje, da je mogoče opaziti demografske razlike (vera, stopnja izobrazbe, narodnost itd.) in tudi razlike v razumevanju življenja v skupnosti. Ob koncu se avtor dotakne tudi prednosti in slabosti ter pomena podeželja ob soočanju z ukrepi za preprečevanje širjenja novega koronavirusa in covida-19.

The aim of the study is a spatial and statistical analysis of hearing loss of various types (conductive, sensorineural, mixed) and deafness in the adult population of the Chelyabinsk region, assessment of its dynamics and the impact of environmental stress in the place of residence. The study materials were data from the regional audiological center of the Chelyabinsk regional clinical hospital for the period from 2016–2020. Epidemiological issues of the spread of diseases were studied using the methods of spatial analysis, in the R software environment. The main tasks of spatial analysis were to visualize a point pattern from the geographical coordinates of the patient’s places of residence, assess the properties of the spatial process that generates this point pattern, test the hypothesis about the spatial randomness of this process and the influence of the ecological situation on it. It was found that more than half of all primary visits were patients with bilateral sensorineural hearing loss. The number of patients who applied for the year during the observation period fluctuates within the average. Of all hearing impairments, the highest values of relative incidence are characteristic of sensorineural hearing loss, which has a direct relationship with age. The intensity of detection in patients with hearing impairment and deafness is directly related to the size of the living population. The existing division into zones with different ecological situations does not have a statistically significant (p <0.05) effect on the ratio of the number of patients with hearing impairments to the population.

The literature provides many ways to close perforations of the nasal septum (NS), there is no differential approach to the choice of technique depending on the etiological factor. Objective: to study the clinical and morphological features of tissues at the edges of postoperative nasal septum perforations (PNSP) to substantiate the choice of the optimal surgical technique. Materials and methods. 52 patients are divided into 3 groups in accordance with the area (S) of PNSP: 1st S < 1 cm2 (10%); 2nd S 1–2 cm2 (75%), 3rd S > 2 cm2 (15%). In group 2, the subgroups are: 2A – PNSP without curvature of the NS (CNS) (52%); 2B – PNSP with CNS (48%). The state of the mucous membrane (MM) and supporting tissues at the edges of the PNSP, the results of a cytological study from the edges of the PNSP, and specific complaints of the patients were evaluated. Results: In group 1 and 2 at the edges of the PNSP, there was a significant decrease in tissue elasticity compared with group 3, indicating a deficit in supporting tissues (p < 0.05). The ratio of the area of the defect of supporting tissues and PNSP in group 1 was 1 to 3.5, in group 2 – 1 to 1.5, in group 3 – 1 to 1.1. A high degree of elasticity of the posterior edge of PNSP is accompanied by pronounced clinical manifestations, regardless of the size of PNSP, and is confirmed by the cytological picture of inflammation (p <0.01). The presence of CNS enhances the clinical manifestations of PNSPI (p < 0.05). Conclusion: the structure of the edges of PNSP forms the clinical picture of the disease. When choosing a closure method for PNSP, the surgeon must solve the following problems: the size of the NS defect required for replacement is determined not so much by the dimensions of the PNSP as the area of the defect in the supporting tissues of the NS; with a deficit of local tissues, it is advisable to additionally use grafts; MM in the area of the posterior and lower edges has pronounced signs of inflammation, these tissues should be removed during the operation.

Aim of study. Investigation of the dynamics of incidence of the skin and subcutaneous tissue diseases in the population and evaluation of the mortality from these diseases. Material and methods. During the study, data on primary and overall incidence, mortality and the mean age of the population who died from the skin and subcutaneous tissue diseases within the period of 2009-2019. The group contribution of the mortality from complications of these diseases to the average life expectancy decline has been studied. The increment rate (%) was calculated for evaluation of the dynamics of the indices. Assessment of the relations between the indices was performed via the Spearman’s rank-order correlation. Results. Over the period from 2009 to 2019, the overall and primary incidence of skin and subcutaneous tissue diseases in the population demonstrated a decrease by 21.54% and 27.67%, respectively, in Krasnoyarsk; by 9.55% and 11.87%, respectively, in the Siberian Federal District; by 8.89% and 17.33%, respectively, in the Russian Federation. We have revealed statistically significant correlations between the overall incidence and the contribution to the life expectancy (r=-0.745, p=0.008), overall incidence and mortality (r=-0.682, p=0.021), mortality and the contribution to the life expectancy (r=0.936, p<0.001) as well as between the mortality and mean age at death (r=0.800, p=0.003). Conclusion. Diseases of the skin and subcutaneous tissue remain a severe medical and social problem. The correlations revealed between the incidence and mortality testify to the low detection rate of skin diseases, which points at the necessity to increase the quality of detection and diagnosis of this group of diseases in the Krasnoyarsk Krai territory in order to decrease the mortality from their complications and increase the life expectancy for the population of this region.
