A TOOTH OF THE EXTINCT LAMNID SHARK, COSMOPOLITODUS PLANUS COMB. NOV. (CHONDRICHTHYES: ELASMOBRANCHII) FROM THE MIOCENE OF POHANG CITY, SOUTH KOREA
Authors: Yun Chan-gyu
Published: July 2021

An isolated, upper lateral tooth of the extinct lamnid shark Cosmopolitodus planus (Agassiz, 1856), is described from middle Miocene marine deposits (possibly the Duho Formation) in Pohang City, South Korea. This is the first confirmed record of this taxon in the Korean Peninsula. The tooth is less than half the size of a large tooth of this species, suggesting that the tooth comes either from an intermediate or posterior position within the upper jaw, or from a young individual. This report further supports the hypothesis that epipelagic or pelagic sharks were already distributed throughout the entire East Sea in the middle Miocene. It is recommended that the species planus should be transferred to the genus Cosmopolitodus based on numerous similarities with the type species of this genus, C. hastalis (Agassiz, 1838).

Published: July 2021

Widespread use of telemedicine as a method for remote medical care provision can become one of the most promising ways to optimise modern healthcare. This article proposes a methodology for adult health telemedicine screening using a system for analysing unstructured data of monitoring chronic non-communicable diseases in the population. This method is based on the risk estimation by the Decision Rules approach, and the fuzzy set theory is used as a description tool. Scientifically-based comprehensive clinical approach for the development of medical questionnaires, the knowledge of which depends on a large scientific base in the field of screening, propaedeutic, taking into account the standards and requirements of health assessment in the Russian Federation, is a fundamental difference from the existing analogues. Expert system of telemedicine questionnaire screening allows determining the health risks by specific profiles, to develop a final personalised judgment with recommendations for a healthy lifestyle, further examination, treatment, and prevention of chronic non-communicable diseases.

Published: July 2021

The purpose of this study was to evaluate the structural transformations of Wistar rats liver after oral administration of lead salts. Under the conditions of acute experiment during 5 days the Wistar rats were orally administered the lead acetate solution in the amount of 3 mg/kg. Histological studies were carried out at OSMU upon the completion of the experiment. Effect of toxic doses of lead causes symptoms of both steatosis and hydropic degeneration of the liver. It is assumed that the appearance of hepatic steatosis reflects the reaction of hepatocytes to hemic hypoxia caused by the action of lead, while the signs of hydropic degeneration expressed in varying degrees reflect its direct toxic effect.

Background: With disturbance of the systemic blood supply, the body experiences hypoxia and stress. Under stress of any etiology, there is a non-specific rearrangement of physiological and biochemical processes. These processes occur under the influence of corticosteroid hormones. Aim: To determine the level of corticosteroid receptors in the kidneys of rats at different times after systemic ischemia-reperfusion. Methods: The study included 80 male white rats. All the animals were divided into 2 groups. A model of systemic ischemia-reperfusion was created in the main group (n=70). Further, on 1, 3, 5, 7, 14, 21 and for 35 days, we determined the level of gluco - and mineralocorticoid receptors in the kidneys. Results: In the animals of the main group, we observed a short-term period (during the first 3 days) of a decrease in the content of both glucorticoid (p<0.05) and mineralocorticoid (p<0.01) receptors. The dynamics of recovery of the level of corticosteroid receptors was 3 times faster than that of mineralocorticoid receptors. Conclusions: The dynamics of corticosteroid receptors’ level in the kidneys of rats after ischemia caused by an arrest of systemic circulation show the recovery time after ischemia-reperfusion injury, which ensures the stability of an individual to hypoxia.

Published: July 2021

Aim of this paper is to estimate crystallogenic properties of gastric mucosa in connection with its microbial contamination. We investigated crystallogenic properties of some biological substrata (gastric mucosa, gastric mucosal layer homogenates) in 12 healthy individuals and 30 patients with ulcer disease complicated in 12 cases by perforation, bleeding or penetration. Biological substrata were received at fibrogastroduodenoscopy. Estimation of crystallogenic properties of biological material was accomplished by classic crystalloscopy. Biological substrata crystalloscopic investigation was accompanied by its traditional microbiological study for Helicobacter pylori and detection of other microorganisms. Our data allow to suppose dual contamination of stomach mucosa both by Helicobacter pylori and Providencia or Morganella. This combination caused elevation of gastric mucosa crystallogenic properties that provoked formation of ulcer. Procrystallogenic potential of this symbiosis may be an important link to the pathogenesis of ulcer disease which realized through microorganism-associated mucosal damage and the progression of complications.

Published: July 2021

Cone-beam computed tomograms of 68 people (age — 21–35) with physiological occlusion and various gnathic dental arches were analyzed by a method developed for identifying the palatal arch index, taken as a height (depth)-to-width dimension ratio. The results of the study revealed that palatal parameters are determined by main variants (types) of the palatal vault. In case of the mesopalatal type of the arch (index value — 35–45%), the width parameters exceeded the depth values by an average of 2.4 times, while the divergence angle of alveolar processes was 116.7 ± 5.6°. The dolichopalatal type of the arch (index value – above 45%) featured domination of the width parameters over the depth-related ones, by an average of 1.8 times, while the alveolar processes divergence angle made up 127.6 ± 6.1°. As far as the brachypalatal type of the arch is concerned (index value — below 35%), the width parameters exceeded the depth parameters by 4.0 times on average, the divergence angle of the alveolar processes being 113.5 ± 5.3°. The obtained data can be used in clinical orthodontics when diagnosing pathologies of the palatal vault, as well as to interpret data from additional methods of examination and to choose the right treatment for issues related to the dental arch shape and size.

Published: July 2021

Early detection of tumor transformation of lichen planus presents a real challenge, since squamous cell carcinoma can develop both from unchanged epithelium, and against the background of inflammatory or precancerous lesions. Another aspect of untimely diagnosis is the unfavorable long-term prognosis of lichen planus, so after complex treatment, 50% of patients have a relapse: 80% — within 2 years and 20% — within 4 years. The aim of this study was to analyze the levels of MMP-8, TIMP-1 and their ratio of MP-8/TIMP-1 in the oral fluid of patients with varied forms of lichen planus. We examined and treated 24 women (35–70 years old). 14 women with oral lichen planus of the mucosa in a typical form were assigned to Group 1; 10 patients with an exudative-hyperemic form - Group 2. Concentrations of the biological markers MMP-8 and TIMP-1 were determined in the oral fluid before and after treatment. Results of the study showed that to assess the severity of oral lichen planus it is essential to evaluate concentration ratio of biological markers MMP-8/TIMP-1 in mixed saliva. Dynamic changes in MMP-8/TIMP-1 levels should be monitored at least once in a quarter.

Published: July 2021

Relevance: Before starting the treatment, the patient's medical history should be carefully studied. Special attention should be paid to the presence/absence of diseases of the cardiovascular system, kidney disease, endocrine pathology, and the psychological state of the body. These diseases can directly affect the dental status and worsen the clinical picture. Psychoemotional stress and inflammatory post-prosthetic complications are reciprocal risk factors. Psychophysiological disorders can lead to the development of dental complications in the oral cavity and vice versa, mucositis can cause a stress reaction in a person. This assumption served as the purpose of this study. Materials and methods: During implant treatment, the analysis of the psychophysiological state in patients with inflammatory post-prosthetic complications was carried out according to 3 parameters (the results of the questionnaire, based on heart rate variability and using software), parallel to the assessment of the dental status in 30 patients. Stress and mucositis should be treated simultaneously, with sedation support where necessary. Outcomes: All patients showed a high level of stress. During the dental examinationthe presence of inflammation of the parotid tissue was detectes. Conclusion: Psychoemotional stress can be one of the initiating factors in the development of inflammatory complications during dental implantation. The main task of a dentist is, first of all, to identify the early stages of the development of the disease, and secondly, to provide not only symptomatic, but also pathogenetic treatment, taking into account the factors that facilitate the development of this pathology.

The aim of the study was to clarify the character of the initiatory activity of pathogenic and nonpathogenic microorganisms in regard to salt solutions. We selected colonies of two microorganisms: Escherichia coli (E. coli) and Staphylococcus aureus (St. aureus) [106 , 108 , 1010, 1012, 1014, 1016, 1018 and 1020 CFU/ml of solution]. A 10% solution of sodium chloride was used as the initiated substance, which made it possible to perform a tezigraphic test. On the basis of model experiments with colonies of some pathogenic and non-pathogenic microorganisms, a new phenomenon was confirmed — microbial initiation of crystal formation (the phenomenon of microorganismassociated crystallogenesis). This phenomenon is universal for microagents, but it also has specific features imposed by the species of the microorganism and its current functional state.

Background: Modern Russian statistics show that the percentage of renal cell carcinoma (RCC) among all oncological diseases has increased and amounted to almost 5% in 2019. The main method of treating RCC is radical nephrectomy in localized RCC, which is supplemented by the removal of regional lymph nodes in locally advanced RCC. Aim: To evaluate early and late postoperative complications in patients with localized and locally advanced renal cell carcinoma. Methods: We’ve analyzed the results of surgical treatment and postoperative complications in 378 patients with clinically proven localized and locally developed RCC. Results: The total number of complications after surgical treatment of patients with localized and locally advanced RCC was 24 (6.3%) patients. Moreover, in the treatment of the localized form of RCC, postoperative complications are 3 times less common than in the locally advanced form of RCC (p <0.05). The most common complication after surgical treatment of RCC was bleeding which we observed in 11(2.9%) patients. Conclusion: After surgical treatment of RCC, the proportion of complications is not high, but they can have unpleasant consequences. In the late postoperative period the most common complication bleeding is followed by lymphorrhea and urinary tract infections.

La reflexión pedagógica se sustenta en la teoría del pensamiento crítico y el concepto de deconstrucción desde la perspectiva del desaprendizaje como marco explicativo acerca de la construcción de conocimiento en el sujeto, para caracterizar el proceso de lectoescritura de la población de injerencia.
Development of a polymer modified Quartz Tuning Fork (QTF) sensor array based Volatile Organic Compound (VOC) classifier
Authors: Datar Suwarna
Published: July 2021

Polymer modified Quartz Tuning Fork sensor array with
three sensors has been developed to classify 1,4-dimethoxy-2, 3-
butanediol (BD), cyclohexanone (CH), ethanol, methanol and acetone with various concentrations. Linear Discriminant Analysis
(LDA), Decision Tree (DT), and Random Forrest (RF) have been
used and evaluated as the classifiers predicting the VOCs and
their concentration. The classifiers were trained with three features:
response time, recovery time, and shift in the resonant frequency of
the sensors. The results have been compared and analyzed for the
performance of each classifier for the present system. RF gives the
best performance as a classifier with an accuracy of classification
more than 95%. We present results of VOC classifier performance
for the QTF sensor array.

Single-Shot Retinal Image Enhancement Using Untrained and Pretrained Neural Networks Priors Integrated with Analytical Image Priors

Published: July 2021

Retinal images acquired using fundus cameras are often visually blurred due to imperfect imaging conditions, refractive medium turbidity, and motion blur. In addition, ocular diseases such as the presence of cataract also result in blurred retinal images. The presence of blur in retinal fundus images reduces the effectiveness of the diagnosis process of an expert ophthalmologist or a computer-aided detection/diagnosis system. In this paper, we put forward a single-shot deep image prior (DIP)-based approach for retinal image enhancement. Unlike typical deep learning-based approaches, our method does not require any training data. Instead, our DIP-based method can learn the underlying image prior while using a single degraded image. To perform retinal image enhancement, we frame it as a layer decomposition problem and investigate the use of two well-known analytical priors, i.e., dark channel prior (DCP) and bright channel prior (BCP) for atmospheric light estimation. We show that both the untrained neural networks and the pretrained neural networks can be used to generate an enhanced image while using only a single degraded image. We evaluate our proposed framework quantitatively on five datasets using three widely used metrics and complement that with a subjective qualitative assessment of the enhancement by two expert ophthalmologists. We have compared our method with a recent state-of-the-art method cofe-Net using synthetically degraded retinal fundus images and show that our method outperforms the state-of-the-art method and provides a gain of 1.23 and 1.4 in average PSNR and SSIM respectively. Our method also outperforms other works proposed in the literature, which have evaluated their performance on non-public proprietary datasets, on the basis of the reported results.
Improved Unequal-Clustering and Routing Protocol
Authors: Alharbi Mohammad , Kolberg Mario
Published: July 2021

We propose improved unequal-clustering and
routing protocol (IUCR) protocol to solve both of these problems jointly. IUCR
provide fixed area clustering
derived from transmission range of network nodes. This clustering also develops strong network backbone that
provides fail-over-proof routing. Efficient routing path is achieved by finding minimal hop-count with
availability of alternate routing path.
Intorno a Geografia Democratica. Fra Marx e Foucault, l’Italia e l’‘Ammerica’
Authors: Celata Filippo
Published: July 2021

Two main and sequential topics are emphasized. The first one is Quaini’s attention for the historically and socially determinated building of the Man/Nature relation, which mainly characterizes his first works written against the remaining positivistic and deterministic interpretations of the so called ‘“Iintegral Ggeography”’. The other topic is the Hish/Low relation, metaphorically representing the dialectic among the social popular practices involved in the territorial exploitment and its representations, usually rooted into oral-tradition cultures, and, on the other side, those linked to the expert knowledges, irreplaceable to appropriately understand the space, always actually influenced by political powers and public institutions.

El presente artículo es derivado del proyecto de investigación: Estrategias pedagógicas para construir la paz en la región: Contribuciones de la Facultad de Educación, Universidad de Nariño, auspiciado por la Vicerrectoría de Investigaciones, Posgrados y Relaciones Internacionales – VIPRI y desarrollado por el Grupo de Investigación para el Desarrollo de la Educación y la Pedagogía – GIDEP, Línea de Investigación “Pedagogía Social”. Tiene como propósito analizar las estrategias pedagógicas para construir la paz en la región, como una contribución de la Facultad de Educación. En el marco de los diálogos de paz se ha invitado a todas las universidades del país a generar sugerencias, a presentar propuestas, iniciativas y estrategias orientadas a construir una paz duradera que aporte al desarrollo económico, político, social y cultural.

 

Para tal efecto, se acudió a un proceso investigativo centrado en los docentes y estudiantes de los programas de la Facultad de Educación, caracterizado por los siguientes aspectos: la investigación se inscribe dentro del paradigma Cualitativo, con enfoque etnográfica y método de acción participativa,incluyendo interacciones entre los investigadores y los investigados.

 

Entre otras conclusiones se destaca que la Facultad de Educación de la Universidad de Nariño, en su Proyecto Educativo, concibe el concepto de la didáctica, como   las teorías y prácticas que en coherencia con la fundamentación pedagógica y en consideración a la naturaleza, la historia y la epistemología de los saberes, permiten desarrollar procesos de transposición   didáctica   que   conllevan a la apropiación consciente y reflexiva del conocimiento científico. Lo anterior, constituyen insumos insustituibles para la construcción de estrategias de paz con miras a fortalecer los procesos derivados del acuerdo de la Habana y el post-acuerdo, la cultura y la educación para paz, el pacifismo, la resolución de conflictos, la mediación, entre otros, para contribuir a la construcción de la paz en el departamento de Nariño.

La Educación Ambiental (EA) en Colombia se institucionalizó de manera efectiva a partir de la promulgación del Decreto 1743 de 1994, mediante los Proyectos Ambientales Escolares (PRAEs) como una de las estrategias de formación ambiental,   así,   su   formulación y ejecución debe fundamentarse como un componente curricular que tienda al desarrollo de valores, desde la interdisciplinariedad, la participación, la formación para la democracia, la gestión y la resolución de problemas del contexto regional. En la investigación se caracterizó el estado actual de los PRAEs de las Instituciones Educativas (IE) oficiales urbanas y rurales de educación básica y media del municipio de Montería, en relación con los requerimientos normativos en su construcción y su dinamización. Mediante una revisión documental, utilizando para el análisis una matriz porcentual de Excel y apoyado en entrevistas a grupos focales de docentes las cuales se analizaron desde el paradigma de la hermenéutica –interpretativa. Los resultados evidencian que, en la mayoría de las IE, los proyectos se ejecutan de manera aislada a la gestión académica, dejando de lado principios didácticos de transversalidad, interdisciplinariedad e integralidad del currículo y generalmente liderados por los profesores de Ciencias Naturales. Se concluye que estos proyectos no han permitido consolidar una educación ambiental integral que tengan en cuenta los aspectos naturales y socioculturales y el mejoramiento de la calidad de las comunidades educativas.

El componente matemático es un aspecto relevante en el aprendizaje de las finanzas, ya que favorece el desarrollo de procesos cognitivos, tales como: razonamiento, visualización, interpretación, direccionamiento, relación, entre otros; que será útil para la comprensión de las diferentes situaciones; la complejidad de sus contenidos y la escasa aplicabilidad que los docentes promueven a partir de ellos, unido a la poca existencia de estrategias didácticas adecuadas que incentiven la motivación y el desarrollo de habilidades para comprenderlos, hacen que su estudio genere poca atracción por parte de los estudiantes.

La investigación buscó visualizar las competencias asociadas al pensamiento financiero mediante el uso de herramientas tecnológicas, en especial de simuladores, en los estudiantes de educación superior. Se enmarcó dentro del enfoque cualitativo, exploratorio, descriptivo y desarrollado bajo el método de Investigación Acción. Fueron seleccionadas como técnicas de recolección de información: observación directa, entrevista estructurada y encuesta. La población de investigación estuvo conformada por 25 estudiantes y 6 profesores que orientan las asignaturas correspondientes al área financiera. Entre los resultados se encontró que a través de la utilización de simuladores, los docentes pueden apropiarse de las TIC como mecanismo de enseñanza más asertivo para estimular el pensamiento financiero y económico en los estudiantes.
