Profile of Fine-Needle Aspiration Cytology (FNAC) of Salivary Gland Lesions with Histopathological Correlation in a Tertiary Care Hospital of Maharashtra
Authors: Butale Pradip Ramabhau , Gawai Sagar Jagdish
Published: April 2021

BACKGROUND Fine needle aspiration cytology (FNAC) is a method for the diagnosis of superficial lesions like swellings of the salivary glands since many years. The present study was undertaken to identify the patterns of salivary gland lesions (SGL) on FNAC and histopathology specimens and also describe the age and sex distribution of SGL. METHODS A total 319 cases of SGL were studied from June 2009 to July 2019 which included both retrospective and prospective cases. A detailed history was taken, clinical and necessary laboratory investigations were done; and then FNAC of salivary gland was done. Histopathology examination of specimens was done whenever available; FNAC and histopathology slides of retrospective cases were reviewed. Correlation between cytomorphology and histomorphology was done only where available. RESULTS The majority of cases was in the age group of 21 - 40 years (42.98 %) with female predominance (53 %) and commonest gland involved was parotid gland (52.97 %) in both the sexes. 138 (43 %) cases were non-neoplastic lesions and 181 (57 %) were diagnosed as neoplastic lesions. Of the 138 non neoplastic lesions, on cytology and histopathology, sialadenitis constituted 110 (79.71 %) cases; most being chronic sialadenitis (107). Out of 181 neoplastic lesions, 142 (77.78 %) were benign while 39 (22.22 %) cases were malignant. Pleomorphic adenoma was the commonest benign neoplasm (71.27 %) and mucoepidermoid carcinoma (66.69 %) was the commonest malignant neoplasm. Histopathological correlation was available in 37 cases. CONCLUSIONS FNAC is useful as an outdoor diagnostic procedure because of the availability of earlier diagnosis in comparison with the histopathological diagnosis. Histopathology correlation is helpful in cases where diagnosis at FNAC is difficult.

Authors: Ramakrishna Saraswathi , Singh Langpoklakpam Chaoba , Chingtham Bijaya , Jain Rahul
Published: April 2021

BACKGROUND Laryngoscopy and endotracheal intubation, a painful procedure, frequently used in airway management is commonly associated with undesired haemodynamic changes like hypertension, tachycardia and arrythmias. Thus, this study was designed to compare haemodynamic stability to laryngoscopy and intubation using single drug induction with etomidate and combined drug induction with propofol and ketamine. METHODS This was a double blind randomised controlled trial, a total of 90 patients of both sexes, aged between 18 - 60 years, who were scheduled for elective surgeries under general anaesthesia in regional institute of medical sciences (RIMS) operation theatre (OT) were divided into two groups. Group PK received propofol (1.5 mg / kg) + ketamine (0.5 mg / kg) and Group E received etomidate (0.3 mg / kg) as induction agents. The haemodynamic parameters (systolic blood pressureSBP, diastolic blood pressure-DBP, mean arterial pressure-MAP, heart rate-HR) were recorded before induction, immediately after induction, 1, 3 and 5 mins after intubation. Side effects like myoclonus and post-operative nausea and vomiting were also noted. RESULTS SBP, DBP, MAP which were recorded, before induction considered as the baseline, and after induction, were comparable between the two groups. SBP, DBP and MAP compared at 1, 3 and 5 mins after intubation showed statistically significant difference between the two groups with propofol-ketamine group showing better haemodynamic stability. The HR between both the groups at various time intervals were comparable and not considered statistically significant. The side effect associated after induction was myoclonus in 14 patients in Group E i.e. 31 % and post-operative nausea vomiting was observed in 8 patients in Group E i.e. 18 %. CONCLUSIONS Thus, in view of haemodynamic stability during laryngoscopy, intubation and side effect profile; propofol and ketamine combination proves to be a better alternative compared to etomidate according to our study.

Published: April 2021

BACKGROUND Occupational ocular injuries are very common in industrial and agricultural workers. These are important and preventable causes of ocular morbidity. Objective of the study was to profile occupational ocular trauma clinicoepidemiologically. METHODS A prospective study was done by collecting data from a standardised questionnaire and complete ophthalmological examination of patients with occupational eye trauma attending VSSIMSAR, Burla, between January 2019 and October 2020. RESULTS Out of 128 cases of work related injuries, males were 85 %. 48 % of the cases were between 21 - 40 years. Out of all cases 66 % injuries were related to industrial work followed by 29 % in agricultural sector and farming. 3 % of cases were due to blast injury. Also there were 3 % cases of chemical conjunctivitis. Most injuries were closed globe (85 %), mostly involving zone 1 (91 %). Open globe injuries were 15 %, majority of them involved zone 2 (47 %). Ocular superficial foreign bodies were the most common clinical entity (60 %), majority of them being metallic in nature (37.5 %). In 4 % cases IOFBs were found. Cornea was the most common ocular structure to get injured (69 %). Out of all cases, 50 % had ocular trauma score (OTS) of 4, and 4 % cases had OTS 2. 48 % of patients presented within 6 hours of injury. 42 % patients were not aware of any eye protective gear at work and 30 % patients were aware but did not use any eye protection. CONCLUSIONS Eye trauma in workplace is an important public health concern in economically productive population. Significant proportion of these injuries is avoidable by using standardised eye protective devices. Attention need to be given for instruction, enforcement of protective eye wear use, and frequent prevention campaigns.

Autobiography and Self-Reflection in Alexander Solzhenitsyn’s “The GULAG Archipelago”
Authors: Shсhedrina Nellya M.
Published: April 2021

“The GULAG Archipelago” is based on historical and autobiographical material. Autobiography is a key feature of the works of Alexander Solzhenitsyn. This style trait manifests itself in the plot, composition, is expressed in the ways of self-reflection, methods of self-identification, in the functions and role of the author-narrator. The retrospective component, as well as the identity of the author and the narrator, the identity of the author and the character, are of fundamental importance. The type of narration chosen by Solzhenitsyn for “The Archipelago” opened up inexhaustible possibilities of fictional and documentary prose as a genre that conceals a way of correlating autobiographical and factual material. At the same time, the author was also a witness to what was happening and conveyed the details, the spirit of his time. Solzhenitsyn’s autobiography is special: it is not only the use of the facts of the writer’s biography, it is the desire to convey their thoughts as a result of the experience through the psychological experiences, thoughts and feelings of the author. The writer draws a spiritual rebirth of a person in the labor camp, reveals moments of repentance, the development of spiritual stoicism. Hard labor elevated Solzhenitsyn and became the highest point from which the most important stages of his life can be counted.

Published: April 2021

The article deals with the coverage of the life and activities of Kalmyks in the South of Russia in the 19th century in the regional periodicals. Particular attention is paid to reflecting the processes of getting used to the nomadic Oirat tribes in the economy and culture of the sedentary Russian population. The question is raised about the typology of the provincial and regional press. The results of a comparative analysis of publications about Kalmyks in various local newspapers are presented. It is shown that the publicists of that time had different points of view on the Kalmyk question. The relevance is due to the need to study the information and propaganda component of the adaptation and integration processes of the Kalmyk people in the Russianspeaking and Orthodox-oriented environment. A review of the scientific literature on the topic is presented. The research has been carried out on the basis of the methodology of the systems approach and the principles of historicism using typological methods for publications and journalistic texts. The novelty of the study is seen in the fact that it is the first to show that the numerous materials of these publications on Kalmyk problems were aimed not only at historical and ethnographic research and acquaintance with them to the wide Russian-speaking public, but carried an educational, civilizational and organizational character directed by their own information and communication field directly in the environment of Kalmyk nomad camps.

The article presents issues related to the sealing slurry technology concerning gelling processes (i.e., static built-up of gel strength of cement slurries). Based on research conducted around the world, it can be concluded that the rate of gelling of the cement slurry has an important role in the process of preventing possible gas exhalations from the annular space. After the cement slurry is pumped into the borehole (especially in zones with shallow gas horizons), the so-called migration (exhalation) of the formation medium (i.e. uncontrolled outflow of e.g. gas from the annular space) may occur. The most important caused of gas migration from the shallow horizons after casings cementation are the inability to maintain a certain overpressure by the column of the binding cement slurry and too long binding of the cement slurry after pumping into the borehole. The initially liquid cement slurry, when pumped out of the casing, acts as a liquid, creating a certain hydrostatic pressure on the deposit. e.g. gas. However, after some time, the period of building the static gel strength (SGS) starts until the cement sets. The SGS building process, i.e. gelling of the cement slurry, reduces the ability to transmit hydrostatic pressure to the reservoir. The Oil and Gas Institute – National Research Institute has tested a number of cement slurry formulations characterized by different gelling and bonding times. Slurries were made on the basis of three typed of latex with the symbols L1, L2, L3, two types of water glass with symbols S1, S2, amorphous silica with the symbol CB, nano-components based on n-SiO2 and n-Al2O3 with the symbols NS and NA as well as high-molecular weight polymer with the symbol GS. Different amounts of setting accelerator were used with the tested slurries. Tests were carried out for eighteen cement recipes, which made it possible to select the optimal compositions of slurries with short gelling and setting times. The samples containing one of the types of latex in the appropriate concentration, the GS polymer, as well as those containing n-SiO2 and n-Al2O3, showed a very advantageous course of the gelation plot (static build-up of gel strength). Their TT transition times, reflecting the course of gelation, ranged from several to several tens of minutes (which is a proof of high ability to prevent gas migration from shallow gas accumulations). The cement slurries developed at the Oil and Gas Institute – National Research Institute, due to their good technological parameters, could be used in the process of cementing casing strings.

The article was created on the grounds of numerical modelling of shaped charges with a focus on the unconventional shape of their liners. The standard shaped charge of the “deep penetrating” type is equipped with a conical liner made of copper. Three various geometries of shaped charges featuring unconventional shape have been modelled and compared with the classical model of a shaped charge. The shaped charges have been compared for maximum pressure during detonation, cumulative jet velocity, kinetic energy gained and length of cumulative jet after 22 µs. The purpose of modelling shaped charges, featuring unconventionally formed liners, was to check whether they are able to improve the perforation job parameters in oil and gas wells. Perforation of the borehole is a critical job, enabling the initiation of hydrocarbons production from a specific reservoir. The job consists in making series of channels perpendicular to the borehole axis, penetrating casing walls, the cement layer and the formation rock, in order to create a hydraulic link between the borehole and the reservoir of hydrocarbons. In the oil industry, the “deep penetrating” type shaped charges are designed in order to provide optimal length of the perforation channel, while maintaining its adequate perforating diameter. Nowadays, the most commonly deep-penetrating shaped charges used, are the axially-symmetric shaped charges with conical liners made of copper powders. The charges create a cumulative jet reaching a velocity of approx. 7000 m/sec and are able to penetrate up to 1 m of rock matrix in favourable conditions. The article describes the parameters of shaped charges, that have been obtained as a result of numerical modelling. In order to finally confirm the target penetrating ability by the modelled shaped charges, one should check their real physical models in fire-ground conditions.

Published: April 2021

The use of video-endoscopic equipment in pediatric rhino-surgery necessitates a thorough study of the structure of the nasal cavity structures at different age periods. The aim of the study was to study the width of the nasal meatuses in childhood based on craniometrics data. Craniometry of 65 children's skulls was performed, divided into six groups (infancy, early childhood, first and second childhood, adolescence and youth). It was found that the width of the nasal meatuses increases unevenly with the age of the child; periods of the permanency are replaced by periods of growth. The maximum values of the width of the lower and middle nasal meatuses of the skull reach in adolescence, and the general meatuses - in adolescence. Also, an increase in the width of the middle and common nasal meatuses was revealed along their length from the anterior to posterior edges of the nasal conches by an average of 30%, while the width of the lower nasal meatuses remains constant. The ratios of the width of the lower and middle nasal meatuses to the width of the common nasal passages were determined depending on age. The width of the inferior nasal meatus to the width of the common nasal meatus at 1-1.5 years is 1: 2 at the level of the anterior end of the inferior nasal conchae and 1: 3 at the level of its posterior end, in other age groups it is 1: 1.5 and 1: 2 respectively. The width of the middle nasal meatus to the width of the common nasal meatus at the level of both ends of the middle meatus in each age group is 1: 1. The obtained data are of clinical importance for the choice of trans-nasal surgical access, for the choice of the size of endoscopic instruments, the diameter and angle of view of endoscopes, the preservation of age-related physiological relationships of the structures of the nasal cavity, and the reduction of the risk of intraoperative complications. Up to 4 years old, it is recommended to use endoscopes and endoscopic instruments of the smallest diameter; over 4 years old, the size of the nasal passages makes it possible to increase the diameter of the endoscopic set to improve access.

The actuality of the problem is associated with an increase in the number of patients with cholelithiasis of working age and a significant increase in cholecystectomies not only in Russia, but throughout the world. It is known that more than 2,5 million are performed annually. Moreover, 5-40% of operated patients develop postcholecystectomy syndrome, which is manifested by recurrent abdominal pain and cholegenic diarrhea. The aim of the study is to assess morphofunctional changes in the mucous membrane of various parts of the intestine in patients with postcholecystectomy syndrome. Histological, histochemical, morphometric and bacterioscopic, parasitological methods were used to study 42 biopsy specimens of the mucous membrane of various parts of the intestines of patients who underwent cholecystectomy. The control group consisted of 18 biopsies of practically healthy individuals. To objectify the study, a morphometric study of the mucous membrane of the duodenum according to 34 parameters, of the cecum and sigmoid colon according to 22 parameters was carried out. In the mucous membrane of the duodenum, chronic duodenitis of varying degrees of activity of the pathological process and atrophy of the intestinal villi were revealed, the intestinal glands were shortened, the intestinal villi are less wide. The epithelial layer of intestinal villi and intestinal glands was abundantly infiltrated with neutrophilic granulocytes. The density of the inflammatory cellular infiltrate in the stroma of the intestinal villi and intestinal glands increased. On the surface of the epithelial layer of the intestinal villi and between the intestinal glands, campylobacters were often found, less often - cryptosporidia. In the mucous membrane of the cecum and sigmoid colon, chronic colitis of varying degrees of activity of the pathological process and atrophy of the intestinal glands were revealed. The thickness of the mucous membrane and the depth of the intestinal glands were lower than normal. Thus, in patients with postcholecystectomy syndrome, pronounced morphometric and histological changes were revealed in the mucous membrane of various parts of the intestine, while the depth and degree of its damage were more significant in its proximal parts.

Traumatic injuries and fractures of the lower jaw are an urgent problem in maxillofacial surgery and traumatology. The strength of the bone tissue of the lower jaw has been studied on 90 lower jaws of adults. All jaws are systematized into three groups: with intact bite, partial and complete loss of teeth. To assess the architectonics of the bone tissue of the mandibular body, sagittal and frontal cuts were made in the molar region. It has been established that, in the case of a complete set of teeth, the ultimate strength of the bone tissue in the area of the incisors is 441.3 ± 32 MPa; in the area of premolars 411.9 ± 20 MPa; molars 431.3 ± 24 MPa; in the area of the base of the coronoid process 156.9 ± 14 MPa; in the area of the base of the condylar process 205.9 ± 19 MPa. To the greatest extent, with partial loss of teeth, the strength of bone tissue in the region of the molars and the angle of the lower jaw changes in Kennedy classes I and II. With the complete loss of teeth, the values of bone strength in the area of molars, angle and condylar process decreased by 22.5-27.7%, in the area of incisors by 6.7%. It was shown that with a full set of teeth, class II according to U. Lekholm and G. Zarb was most often observed - in 66.7% of cases, less often class I - in 16.7% and class III - in 13.3%, class IV was observed most rarely - in 3.3% of cases. With complete loss of teeth, the presence of mainly II and III classes is noted. It has been proven that the strength of the bone tissue of the lower jaw body decreases significantly with age with the loss of teeth in an adult, which is associated with significant changes in the quality of bone tissue.

The study of anthropometric and bioimpedance parameters in assessing the physical development of patients helps to clarify the diagnosis, predict the course of the disease, and identify groups of increased risk for the development of the disease. The aim of this study was to identify anthropometric and bioimpedance metrics in patients with stomach cancer. Anthropometric and bioimpedansometric examination of 250 patients with verified gastric cancer, 123 men and 127 women was carried out. As a comparison group, the study used the results of anthropometric and bioimpedance measurements of healthy 221 men and 267 women of the same age in the Krasnoyarsk Territory population. To determine a set of anthropometric and bioimpedansometric variables, allowing to classify the observed people depending on the presence (group of patients with gastric cancer) or the absence of stomach cancer (group of healthy people), the method of discriminant analysis was applied. To test the hypothesis about the homogeneity of the covariance matrices of the compared groups, the multidimensional Box M-criterion was used. The statistical significance of the power of the discriminant function was assessed using the Wilks test. For each discriminant function, the role of its components was assessed by comparing the matrices of total variances and covariances using the F-test. Shoulder diameter for men and women, chest diameter (transverse size) for men and women, waist circumference for men, waist / hip ratio for men and women; lean mass in men, total fluid in men, fat mass in women, phase angle in men and women are statistically significantly different in the observed groups. The developed discriminant models with an accuracy of 75-77% suggest the presence of gastric cancer in patients and can be used in clinical practice at the stage of general medical examination in groups at increased risk of developing the disease.
ETHNO-TERRITORIAL FEATURES OF SOME OSTEOMETRIC PARAMETERS OF THE PROXIMAL PHALANGES OF THE HAND IN MALE CHILDREN AND ADOLESCENTS IN TAJIKISTAN AND WESTERN INDIA

Published: April 2021

The aim of the study is to establish ethno-territorial differences in the linear parameters of the proximal phalanges of the fingers in children and adolescents of the male sex of Tajikistan and Western India, regression equations that allow determining the nature of the dependence of the age of the examined and linear sizes of phalanges. On 366 radiographs of the right hand in children and adolescents aged 6-17 years from Tajikistan and India (Mumbai), the length of the proximal phalanges and the width of their diaphysis were measured. To determine the relationship between the age and the length, as well as the width of the diaphysis, Spearman's nonparametric correlation coefficient was used, because the age distribution does not correspond to normal. One-way ANOVA demonstrates the statistical significance of the increase in the length and width of the diaphysis of the proximal phalanges in boys and young men of Tajikistan and India with age, but the growth of these bones is uneven. For both Tajik and Indian boys, the closest correlation with age was found for the length of the second finger phalanx. It was found that in children in the smallest regions compared, the correlation was determined between their age and the length of the phalanx of the fifth finger. The length of the phalanx of the third finger increased most significantly with age in boys of the compared ethnic groups. The smallest height in length was determined for the phalanx of the fifth finger in boys in India and for the phalanx of the first finger in adolescents in Tajikistan. The maximum growth of the diaphysis in width was observed in the phalanx of the second finger, the smallest in the phalanges of the first and fifth fingers. The highest reliability was found with the length of the phalanx of the second finger. For Tajik boys, the parameters of the length of the phalanges of the III and IV fingers also have a correlation coefficient, therefore, they can be used to identify their age.

The greater omentum is an organ in which metastases of malignant neoplasms of the female reproductive system are often formed. The issues of adaptive and reactive transformations of the greater omentum under conditions of a tumor process in the organs of the female reproductive system have been insufficiently studied. The aim of the study was to elucidate morphological and functional ultrastructural and immune-histochemical changes in the greater omentum in women with ovarian tumor lesions. Using the methods of light and electron microscopy, immunohistochemistry and morphometry, the ovaries of 48 women were examined, who were diagnosed with poorly differentiated serous-papillary adenocarcinoma stage II (20 patients, group 1), stage III (28 patients, group 2). In stage III patients, numerous tumor metastases were detected in the greater omentum. The results of the study showed that in the patients of the 2nd group, in the peri-tumor areas of the greater omentum, the vessels of the microvasculature were dilated, in the connective tissue, moderate edema and leukocyte infiltration were observed. Immuno-histochemical markers showed an increase in the number of immunocompetent cells, mainly T-lymphocytes in the tumor and in the peri-tumor areas. In the tumor and in the surrounding areas of the greater omentum, the process of neoplasm of blood capillaries was noted, differences in the density of collagen fibrils in different parts of the serous membrane were revealed, and the presence of numerous holes was shown, the sizes of which were reduced in areas with metastases. The results obtained show the adaptive and reparative capabilities of the structures of the greater omentum during the tumor process in the organs of the female reproductive system, indicate the important role of the greater omentum in providing protective reactions in the abdominal cavity. In response to the invasion of tumor cells, the processes of angiogenesis are activated in the greater omentum, and the number of immunocompetent cells increases in neo-lymphogenesis. The materials of the study indicate a significant plasticity and reactivity of the greater omentum under conditions of a tumor process in the body. However, the presence of a pronounced proliferative activity of tumor cells in tumor metastases indicates that these adaptive capacities are insufficient to resist tumor invasion into the greater omentum.

A pesquisa trata-se de um estudo elaborado para investigar a trajetória de formação acadêmica dos professores pertencentes ao subcampo da Educação Química (EQ) dos cursos de Licenciatura em Química nas Instituições de Ensino Superior públicas do estado do Paraná. A investigação caracterizou-se como uma pesquisa qualitativa, do tipo documental, pois utilizou-se de documentos, como os currículos Lattes disponíveis na plataforma do CNPq, para mensurar informações na construção de dados. Com o estudo bibliométrico, buscou-se mapear os dados extraídos dos documentos, com o intuito de aferir o nível, a área, o local e o período de formação dos agentes sociais atuantes no Ensino de Química dentro do campo acadêmico. Para a análise dos dados, utilizou-se da metodologia de Análise de Conteúdo da Bardin (2010), sendo a elaboração de categorias estabelecidas a priori baseadas nas ideias de Bourdieu (2004, 2017a), referente ao capital cultural. Os resultados apontaram que, o subcampo da EQ é constituído por mestres e doutores, formados principalmente no estado do Paraná, Santa Catarina e São Paulo, com formações nem sempre lineares ao campo científico. Além do mais, os resultados confirmaram a expansão do subcampo da EQ no Paraná, o que é indicado pelo crescimento de agentes com formações específicas para atuação nos cursos de Licenciatura em Química, sendo este um apontamento para a consolidação e constituição da área como um campo de estudo.
Das relações entre o currículo prescrito e o currículo avaliado
Authors: Pereira Marcus Vinícius Medeiros
Published: April 2021

O texto apresenta a análise curricular das cinco edições do Exame Nacional de Desempenho dos Estudantes – Música realizadas até o momento, no que se refere à seção de conhecimentos específicos, relacionando-a com estudos anteriores a respeito das Diretrizes Curriculares Nacionais que orientam a construção de projetos pedagógicos de cursos de Licenciaturas em Música, e que analisaram esses projetos de cursos no Brasil. O objetivo é correlacionar currículo prescrito e currículo avaliado, explicitando a presença de uma tradição musical ligada a práticas conservatoriais que se perpetua na área, bem como o espaço restrito conferido à educação básica nesses documentos. A metodologia de análise documental utilizada foi a codificação e categorização propostas pela Teoria Fundamentada nos Dados. Os resultados evidenciaram uma hierarquia de conhecimentos ligados às práticas musicais eruditas: tanto produtos (repertórios) quanto processos (sistematizações e teorizações sobre música). Mostraram, ainda, um movimento de mudança em direção à presença de conhecimentos relacionados às áreas da educação e da educação musical, o que coincide com a avaliação voltada, a partir de 2011, somente para as licenciaturas em Música. Os cursos não parecem considerar os contextos em que estão inseridos, e tanto seus projetos (currículo prescrito) quanto o ENADE (currículo avaliado) evidenciam um currículo do tipo coleção. Por fim, indica-se que as mudanças – se desejadas – podem começar nas ações individuais e coletivas dos docentes, cuja participação na elaboração das políticas de avaliação precisa ser mais significativa.
Adaptação acadêmica de estudantes do 1º ano

Published: April 2021

O presente artigo tem como objetivo desenvolver uma reflexão teórica a partir da compreensão dos fenômenos multifacetados que estão presentes no ingresso do estudante no ensino superior. Este constructo contemplou as expectativas que este novo contexto provoca nos estudantes e o impacto das primeiras vivências adaptativas no êxito e permanência do estudante na universidade. A transição e adaptação ao ensino superior constituem verdadeiros desafios e são descritas através de diferentes dimensões adaptativas em relação à instituição, aos estudos, aos seus pares, às exigências de autonomia pessoal e emocional, ou ao planejamento da carreira. Propõem-se alternativas de prevenção ao abandono universitário precoce, aqui entendido como o direito que o estudante possui de iniciar e concluir seus estudos com qualidade, com o devido suporte acadêmico, social e político, disponível nas instituições de ensino superior. Busca-se, portanto, uma reflexão sobre novas práticas formativas nesse nível de ensino diante dos alunos, os quais, potencialmente, estão mais vulneráveis em termos de desenvolvimento de competências. Abrange-se a necessidade de apoio social, psicológico e educativo, destinado a apoiar o êxito universitário dos estudantes e, consequentemente, a conclusão dos seus cursos, fazendo diminuir as taxas de abandono, tendencialmente mais elevadas entre os estudantes do 1º ano.

A vida acadêmica dos estudantes universitários exige dedicação e horas de estudos, de forma que muitos jovens para suportar o estresse e cansaço utilizam psicofármacos visando minimizar essas sensações. O objetivo desta pesquisa foi avaliar o uso de psicofármacos entre estudantes de medicina e odontologia. Trata-se de estudo descritivo, observacional, analítico e transversal, com 1.111 estudantes de duas instituições de ensino superior, regularmente matriculados nos cursos de medicina e odontologia, com idade igual ou superior a 18 anos.  Foi aplicado um questionário estruturado com questões objetivas. As análises estatísticas foram realizadas no programa SPSS 22, e o nível de significância estabelecido como p < 0,05. O uso de psicofármacos ao longo da vida foi informado por 36,7%, enquanto 14,7% fez uso no último mês. A frequência de uso de psicofármacos é maior em situações de estresse, perda familiar ou submissão a cirurgias pelos estudantes. 37,2% afirmaram que obtiveram os medicamentos sem prescrição médica. As classes farmacológicas mais utilizadas foram ansiolíticos, antidepressivos e psicoestimulantes. Estes últimos foram mais consumidos por estudantes de medicina (p<0,05; OR: 2,12). Entre os fatores precipitantes para início do uso estão a demanda do curso (41,6%), outros fatores (33,7%) e problemas familiares (29,1%). 90,8% afirmaram ter consciência dos riscos quanto ao uso.  O estudo verificou alta prevalência de uso não prescrito de psicofármacos entre os estudantes. Diante das necessidades encontradas, faz-se necessária a busca por estratégias de orientação e prevenção pelas universidades.
Jogo didático no ensino de conceitos lean na disciplina de administração de obras
Authors: Viana Marina Ribeiro , Santos Débora de Gois , Vasconcelos Carlos Alberto
Published: April 2021

A mentalidade enxuta visa reduzir ou eliminar as atividades que não agregam valor ao produto através de melhorias contínuas e da redução de perdas. Trata-se de uma filosofia originada na década de 1990 e que, aos poucos, foi incorporada aos currículos dos cursos de Engenharia de Produção e Civil. Sob esse aspecto, por entender que a utilização de jogos didáticos pode ser eficiente, ao passo que estimula a participação e motiva os envolvidos, buscou-se investigar a utilização desse recurso pedagógico na difusão dos conceitos Lean entre futuros profissionais do setor. Diante do exposto, o presente trabalho originou-se de uma experiência com a aplicação do jogo Fábrica de Canetas em uma turma da graduação em Engenharia Civil. Para tal, foram realizadas simulações que permitiram abordar conceitos relativos à Produção Enxuta e ao gerenciamento da produção e, ao final, foi solicitado, aos integrantes dos grupos, a elaboração de um relatório sobre o que foi aprendido.  Após a aplicação do jogo, foi possível observar maior participação dos discentes ao desenvolverem as atividades e ao comentar sobre os aspectos positivos e o que poderiam ser melhorados. Conclui-se, portanto, que os jogos podem auxiliar no ensino de teorias, sendo complementar ao que outrora fora visto em sala de aula.
A comunicação institucional e a internacionalização da educação superior
Authors: Rocha Leandro Cunha , Stallivieri Luciane
Published: April 2021

A internacionalização das Instituições de Ensino Superior (IES) é recomendada a se conduzir de forma abrangente, através de ações comprometidas e direcionadas, contando com a participação de todos os membros das comunidades universitárias. A comunicação institucional é uma das ações que auxiliam na difusão e na visibilidade desse processo. O presente estudo realiza uma revisão de literatura com uma abordagem qualitativa, exploratória e de natureza aplicada. Utilizou pesquisa bibliográfica, análise documental na coleta de dados e análise de conteúdo para o tratamento desses dados, seguindo a lógica indutiva. Conduziu-se através de dois objetivos; (i) apurar a tendência da produção científica em relação à comunicação e/ou promoção da internacionalização das IES e; (ii) determinar pontos de conexão entre os temas comunicação institucional e internacionalização das IES. Constatou-se que a comunicação institucional, na perspectiva internacional, tende a ser utilizada, com maior relevância, para atração de estudantes internacionais, por meio das mídias sociais e páginas eletrônicas; deixando de considerar, entretanto, os demais atores envolvidos nesse processo, ou seja, os docentes, os pesquisadores e os gestores educacionais. Constatou-se ainda que a ênfase das ações de comunicação institucional deixam de evidenciar outras formas de cooperação internacional, fundamentais para a projeção e para a visibilidade de uma IES, tais como resultados de pesquisas e projetos de extensão universitária.
The Agnostic Structure of Data Science Methods
Authors: Napoletani Domenico , Panza Marco , Struppa Daniele
Published: April 2021

In this paper we argue that data science is a coherent and novel approach to empirical problems that, in its most general form, does not build understanding about phenomena. Within the new type of mathematization at work in data science, mathematical methods are not selected because of any relevance for a problem at hand; mathematical methods are applied to a specific problem only by `forcing’, i.e. on the basis of their ability to reorganize the data for further analysis and the intrinsic richness of their mathematical structure. In particular, we argue that deep learning neural networks are best understood within the context of forcing optimization methods. We finally explore the broader question of the appropriateness of data science methods in solving problems. We argue that this question should not be interpreted as a search for a correspondence between phenomena and specific solutions found by data science methods; rather, it is the internal structure of data science methods that is open to precise forms of understanding.

Authors:   , Huaire Veliz Crhistian Leandro
Published: April 2021

La presente tesis tuvo como finalidad servir de guía para el cumplimiento de los requisitos de la norma mundial de seguridad alimentaria BRC, previo a una auditoría de certificación, aplicados a una empresa que elabora chocolate sucedáneo en forma de gotas, denominada de ahora en adelante empresa ABC SAC. Este proceso de implementación surgió como un requisito de unos clientes nacionales, para demostrar y asegurar la calidad, inocuidad y legalidad del proceso de elaboración del chocolate sucedáneo en forma de gotas y así mismo fidelizar al cliente. Para el desarrollo de la presente tesis se definió la situación actual de la organización en relación al cumplimiento de los requisitos de norma mediante la herramienta de autoevaluación BRC v8, con los resultados obtenidos de autoevaluación se procedió a levantar cada una de las no conformidades, teniendo especial cuidado en los requisitos fundamentales ya que el incumplimiento de la declaración de intenciones de algún requisito fundamental dará lugar a que se rechace la certificación, posteriormente se realizó la auditoría interna a fin de verificar el cierre de las brechas correspondientes, y de esta forma lograr la alineación para la auditoría de certificación. Por las características del presente trabajo de investigación se clasifica como cualitativo no experimental y descriptivo.
