Backgraund. Pancreatoduodenal resection (PDR) is the only radical treatment for malignant tumors of the periampullary zone. The development of postoperative pancreatic fistula (POPF) is the most common complication of PDR. The main risk factors for the development of POPF are the narrow main pancreatic duct and the soft, "juicy" pancreatic parenchyma. Thus, it is the stage of formation of a pancretodigestive anastomosis that is of decisive importance for the course of the postoperative period.The aim of the study was to improve immediate surgical treatment outcomes of patients suffering from oncological diseases of the periampullary zone with a soft pancreas and a narrow pancreatic duct.Methods. A novel method to form terminolateral reservoir invagination pancreatojejunostomy has been developed and introduced into clinical practice. The results of treatment of 94 patients with tumors of the periampullary zone were analyzed. Based on preoperative radiological diagnosis and intraoperative findings, such factors of a high risk of POPF development as a soft pancreas and a narrow major pancreatic duct ( 3 mm) were detected in 23 patients (24.4%). In 11 patients who were treated in 2018-2019, a novel method of pancreato-jejunoanastomosis formation was applied. The comparison group consisted of 12 patients who received treatment in 2014-2017; a differentiated approach to the formation of a pancreatodigestive anastomosis was not applied.Results. In patients of the main group, there was a tendency to an increase in the proportion of pylorus-saving PDRs. The only statistically significant difference was the use of reservoir terminolateral pancreatojejunostomy at the reconstructive stage of surgery. Complicated postoperative course was observed in 7 (63.6%) patients of the main group and in all patients of the comparison group (p 0.05). There was also a decrease in the incidence of postoperative pancreatic fistulas from 66.6 to 18.2% (p 0.05) in the study group. Repeated surgery was required in 3 (27.2%) patients of the main group and 7 (58.3%) patients in the comparison group (p 0.05). The lethal outcome was recorded in 2 (18.2%) patients of the main group and in 3 (25%) in the comparison group (p 0.05).Conclusion. A soft, loose pancreas and a narrow main pancreatic duct are the most significant risk factors for complications in the postoperative period. Management of this condition requires a differentiated approach to the treatment option of pancreatodigestive anastomosis formation, depending on the characteristics of the pancreas of an individual patient. The proposed technique for the reservoir terminolateral pancreatojejunoanastomosis formation allowed statistically significantly reducing the incidence of complications from 100 to 63.6% and the incidence of postoperative pancreatic fistulas from 66.6 to 18.2% in high-risk patients..

Introduction. The frequency of occurrence of morbid obesity and neoplasms of the female reproductive system is very high and these conditions aggravate each other. Therefore, it is relevant to simultaneously perform laparoscopic bariatric operations and radical interventions for benign and malignant tumors of the female reproductive system in such cases. The experience of such simultaneous interventions is still small and in the available literature is limited to the description of single cases. The primary issues are the fundamental possibility of combining the two stages in one operation, the technical aspects of such interventions, and the assessment of perioperative safety and immediate results.The aim of the study was to create a technique of simultaneous surgical treatment of the pelvic organs neoplasms and morbid obesity in females, to assess the perioperative safety and immediate results of such simultaneous operations.Methods. The authors present their experience and the first results of simultaneous laparoscopic sleeve gastrectomy and hysterectomies in 9 women with malignant and benign neoplasms of female genitals, suffering from morbid obesity. A method of simultaneous combined surgical treatment of neoplasms of female genitals and morbid obesity has been developed and described.Results. The proposed technique allowed performing two interventions during one procedure in a minimum time, technically in the simplest way without additional complications and risks. The duration of simultaneous operations averaged 162.7 21.8 min., the average blood loss was 247.6 31.0 ml, the pain syndrome on the first day was moderately expressed, no serious complications were observed.Conclusions. The results obtained demonstrated that the morbidity and perioperative safety of simultaneous operations are comparable to those with separate performance of such operations with certain benefits.

Published: January 2021

Introduction. Bleeding in liver injuries is observed during natural disasters, massive injuries, in military field conditions and under other circumstances. The vital need for surgical treatment in these cases is obvious. As a rule, time for assistance is limited, and operations are performed by surgeons who do not have sufficient experience. Intraoperative hemostasis methods are not always effective. The search for intraoperative hemostasis methods has not stopped for many decades. Experimental study of the effect of new agents that allow for reliable hemostasis in liver damage is relevant for medical science and practice.Materials and methods. The experimental study included 116 white Wistar rats of both sexes weighed 230 25 g and 30 Chinchilla rabbits of both sexes weighed 2.5-3.5 kg. The following parameters were identified in experiments in vivo: the duration of bleeding in simulated liver injury without the use of hemostatics and with the use of alufer and viscostat preparations. A morphological study of the regenerative process in the liver was carried out on the 1st - 14th day after the injury. The biopsy material was fixed in 10% formalin solution. Staining of histological sections was carried out with hematoxylin and eosin, as well as Prussian blue (according to Max Perls) to detect iron compounds in tissues.Results. It was revealed that the implementation of hemostasis with the use of the alufer preparation is accompanied by a decrease in circulatory disorders (edema, hemorrhages); characterized by a more pronounced formation of the connective tissue in the area of drug ​​application, which is partially retained (taking into account the time interval of the study) at the site of application.

Introduction. The choice of the optimal type of hernia endoprosthesis, as well as introduction of drugs with a collagen-forming effect into clinical practice, will improve the quality of treatment in patients with ventral hernias due to the formation of the full-fledged connective tissue both in the area of ​​the postoperative scar and in the area of ​​the hernia endoprosthesis placement. The aim of the study was to identify the effect of deproteinized dialysate from vealers blood on neocollagenesis in the area of endoprosthetics.Materials and methods. The experimental study included 80 laboratory white mice, Wistar line. All animals were divided into two groups (control and experimental). A polypropylene hernioendoprosthesis was implanted in animals of both groups. The division into groups was due to the use of deproteinized dialysate from the vealers blood.Results. The use of a polypropylene hernioendoprosthesis for abdominal wall plasty combined with the use of deproteinized dialysate created the necessary conditions for accelerating the processes of proliferation and maturation of fibroblastic cells.Conclusion. The maximum value of the ratio of collagen fibers of types I and III was achieved on the 90th day of the study, the difference between the value of this parameter was 1.24 times greater in the group of animals where deproteinized dialysate was used.

Purpose. Study of technical options and immediate results of primary anastomoses using intraoperative colonic irrigation in the surgical treatment of left-sided colonic tumor obstruction.Material and methods. Of the 128 patients with left-sided colonic obstruction, 20 patients underwent surgery with intraoperative colonic lavage and the formation of a primary colonic anastomosis. The mean age was 61.7 1.4 years. In 5 patients, the compensated stage of colonic malignant obstruction was detected, in 8 patients - subcompensated, in 7 patients - decompensated. Colon icirrigation was carried out by means of antegrade jet injection of 8 -10 liters of isoosmolar solution of electrolytes and was terminated by the introduction of enterosorbent microsorb-P. In 11 cases left-sided hemicolectomy was performed in patients and in 9 cases - resection of the sigmoid colon with primary anastomosis.Results. After surgical interventions various complications were observed in 7 patients. In 2 patients afailure of anastomosis was revealed, the successful treatment of which did not require repeated surgical procedures. In the postoperative period 1 (5.0%) patient died on the 4th day after surgical intervention from cardiopulmonary insufficiency on the basis of concomitant pathology.Conclusion. In the conditions of specialized surgical hospitals after careful evaluation of operational risk with obstructing cancer of the left colon it is possible to use segmental resections of the colon with the imposition of a primary anastomosis with mandatory use of intraoperative colonic lavage . This tactic helps to increase the effectiveness of surgical interventions and provides early rehabilitation of operated patients.

Authors: Araujo Carla Reis de , Sampaio Michel Serra
Published: January 2021

A incorporação de fibras naturais se mostra como uma alternativa promissora na obtenção de materiais compósitos, pois seu baixo custo, alta disponibilidade e propriedades únicas criam oportunidades para novos usos e aplicações dessas fibras. No entanto, o estudo das propriedades dos compósitos obtidos é fundamental na determinação das características do material e seu processo de seleção para aplicação em materiais, pois o compósito deve atender a uma série de requisitos e exigências de propriedades. Com isto, o presente trabalho teve como objetivo a obtenção de compósitos de polietileno com fibras de coco e a sua caracterização através de ensaios mecânicos e análise térmica. Os resultados dos ensaios mecânicos mostraram que os compósitos não apresentaram mudanças significativas na tensão na força máxima com a adição de fibra, mas apresentaram uma diminuição da deformação na ruptura e um aumento do módulo de elasticidade do compósito com a adição de fibra. Os resultados da análise térmica mostraram que a temperatura de fusão (Tm) do polímero é de 130ºC, a degradação das fibras ocorre acima de 200ºC e o polímero se degrada em 485ºC, o que permite o processamento do compósito sem degradar seus constituintes, embora a estabilidade térmica dos compósitos obtidos tenha diminuído com a adição de fibra.

Studying the relationship between leaf pubescence and drought resistance is important for assessing Triticum aestivum L. genetic resources. The aim of the work was to assess resistance of common wheat genotypes with different composition and allelic state of genes that determine the leaf pubescence phenotype. We compared the drought resistance wheat variety Saratovskaya 29 (S29) with densely pubescent leaves, carrying the dominant alleles of the Hl1 and Hl3 genes, and two near isogenic lines, i: S29 hl1, hl3 and i: S29 Hl2aesp, with the introgression of the additional pubescence gene from diploid species Aegilops speltoides. Under controlled conditions of the climatic chamber, the photosynthetic pigments content, the activity of ascorbate-glutathione cycle enzymes and also the parameters of chlorophyll fluorescence used to assess the physiological state of the plants photosynthetic apparatus were studied in the leaves of S29 and the lines. Tolerance was evaluated using the comprehensive index D, calculated on the basis of the studied physiological characteristics. The recessive state of pubescence genes, as well as the introduction of the additional Hl2aesp gene, led to a 6-fold decrease in D. Under the water deficit influence, the fluorescence parameters profile changed in the lines, and the viability index decreased compared with S29. Under drought, the activity of ascorbate peroxidase, glutathione reductase and dehydroascorbate reductase in the line i: S29 hl1, hl3 decreased 1.9, 3.3 and 2.3 times, in the line i: S29 Hl2aesp it decreased 1.8, 3.6 and 1.8 times respectively, compared with S29. In a hydroponic greenhouse, line productivity was studied. Compared with S29, the thousand grains mass in the line i: S29 hl1, hl3 under water deficit was reduced. The productivity of the line i: S29 Hl2aesp was significantly reduced regardless of water supply conditions in comparison with S29. Presumably, the revealed effects are associated with violations of cross-regulatory interactions between the proteins of the trichome formation network and transcription factors that regulate plant growth and stress response.

Published: January 2021

In the mid-20th century, the first case of infection of European bees Apis mellifera L. with the ectoparasite mite Varroa destructor was recorded. The original host of this mite is the Asian bee Apis cerana. The mite V. destructor was widespread throughout Europe, North and South America, and Australia remained the only continent free from this parasite. Without acaricide treatment any honeybee colony dies within 1–4 years. The use of synthetic acaricides has not justified itself – they make beekeeping products unsuitable and mites develop resistance to them, which forces the use of even greater concentrations that can be toxic to the bees. Therefore, the only safe measure to combat the mite is the use of biological control methods. One of these methods is the selection of bee colonies with natural mite resistance. In this article we summarize publications devoted to the search for genetic markers associated with resistance to V. destructor. The first part discusses the basic mechanisms of bee resistance (Varroa sensitive hygienic behavior and grooming) and methods for their assessment. The second part focuses on research aimed at searching for loci and candidate genes associated with resistance to varroosis by mapping quantitative traits loci and genome-wide association studies. The third part summarizes studies of the transcriptome profile of Varroa resistant bees. The last part discusses the most likely candidate genes – potential markers for breeding Varroa resistant bees. Resistance to the mite is manifested in a variety of phenotypes and is under polygenic control. The establishing of gene pathways involved in resistance to Varroa will help create a methodological basis for the selection of Varroa resistant honeybee colonies.
Polymorphism of the mannose-binding lectin gene in the Arctic indigenous populations of the Russian Federation
Authors: Tereshchenko S. Yu. , Smolnikova M. V.
Published: January 2021

Mannose-binding lectin (MBL) is a pattern recognizing acute-phase protein of the innate immunity system actively involved in the elimination of a wide range of pathogenic microorganisms by activating the lectin pathway of the complement system. A significant part of the human population has a congenitally low production level and/or low MBL activity due to the carriage of various MBL2 variants, which can modify the course of a wide range of infectious diseases. The genotype and haplotype frequencies of the MBL2 polymorphisms have significant population differences. So far, data on the prevalence of the MBL2 genotypes in indigenous populations of the Russian Arctic regions have not been available. The aim of the study was to analyze the frequency and ethnic specificity of the distribution of allelic variants of the MBL2 polymorphisms rs11003125, rs7096206, rs7095891, rs5030737, rs1800450 and rs1800451 and their haplotypes in the populations of the Taimyr Dolgans-Nenets region of the Krasnoyarsk territory (Nenets, Dolgans-Nganasans, Russians). Data on the genotype and haplotype frequencies of the MBL2 gene among indigenous peoples of the Russian Arctic territories was first obtained in the study. The HYPA haplotype prevalence associated with a high concentration of MBL amounted to 35.4 % for Russian newborns in Eastern Siberia, corresponding to the one for European populations (27–33 %). In newborns of the Arctic populations, the prevalence of HYPA haplotype was significantly higher than in Russians and amounted to 64 % for Nenets and 56 % for the DolgansNganasans, which is close to the one detected for the Eskimos and North American Indians (64–81 %). Populations of Nenets and Dolgans-Nganasans demonstrated a significantly lower prevalence of MBL-deficient haplotypes compared with Caucasians of Eastern Siberia (3.9, 6.4 and 21.3 % respectively). Isolated Arctic populations were suggested to experience some intracellular infections (tuberculosis, leprosy) historically later and, unlike Caucasoid populations, to retain the high activity of the lectin complement activation pathway formed in the early stages of human evolution.

Hundreds of genome-wide association studies (GWAS) of human traits are performed each year. The results of GWAS are often published in the form of summary statistics. Information from summary statistics can be used for multiple purposes – from fundamental research in biology and genetics to the search for potential biomarkers and therapeutic targets. While the amount of GWAS summary statistics collected by the scientific community is rapidly increasing, the use of this data is limited by the lack of generally accepted standards. In particular, the researchers who would like to use GWAS summary statistics in their studies have to become aware that the data are scattered across multiple websites, are presented in a variety of formats, and, often, were not quality controlled. Moreover, each available summary statistics analysis tools will ask for data to be presented in their own internal format. To address these issues, we developed GWAS-MAP, a high-throughput platform for aggregating, storing, analyzing, visualizing and providing access to a database of big data that result from region- and genome-wide association studies. The database currently contains information on more than 70 billion associations between genetic variants and human diseases, quantitative traits, and “omics” traits. The GWAS-MAP platform and database can be used for studying the etiology of human diseases, building predictive risk models and finding potential biomarkers and therapeutic interventions. In order to demonstrate a typical application of the platform as an approach for extracting new biological knowledge and establishing mechanistic hypotheses, we analyzed varicose veins, a disease affecting on average every third adult in Russia. The results of analysis confirmed known epidemiologic associations for this disease and led us to propose a hypothesis that increased levels of MICB and CD209 proteins in human plasma may increase susceptibility to varicose veins.
The role of microRNAs in learning and long-term memory
Authors: Grinkevich L. N.
Published: January 2021

The mechanisms of long-term memory formation and ways to improve it (in the case of its impairment) remain an extremely difficult problem yet to be solved. Over the recent years, much attention has been paid to microRNAs in this regard. MicroRNAs are unique endogenous non-coding RNAs about 22 nucleotides in length; each can regulate translation of hundreds of messenger RNA targets, thereby controlling entire gene networks. MicroRNAs are widely represented in the central nervous system. A large number of studies are currently being conducted to investigate the role of microRNAs in the brain functioning. A number of microRNAs have been shown to be involved in the process of synaptic plasticity, as well as in the long-term memory formation. Disruption of microRNA biogenesis leads to significant cognitive dysfunctions. Moreover, impaired microRNA biogenesis is one of the causes of the pathogenesis of mental disorders, neurodegenerative illnesses and senile dementia, which are often accompanied by deterioration in the learning ability and by memory impairment. Optimistic predictions are made that microRNAs can be used as targets for therapeutic treatment and for diagnosing the above pathologies. The importance of applications related to microRNAs significantly raises interest in studying their functions in the brain. Thus, this review is focused on the role of microRNAs in cognitive processes. It describes microRNA biogenesis and the role of miRNAs in the regulation of gene expression, as well as the latest achievements in studying the functional role of microRNAs in learning and in long-term memory formation, depending on the activation or inhibition of their expression. The review presents summarized data on the effect of impaired microRNA biogenesis on long-term memory formation, including those associated with sleep deprivation. In addition, analysis is provided of the current literature related to the prospects of improving cognitive processes by influencing microRNA biogenesis via the use of CRISPR/Cas9 technologies and active mental and physical exercises.
Generation of donor organs in chimeric animals via blastocyst complementation
Authors: Babochkina T. I. , Gerlinskaya L. A. , Moshkin M. P.
Published: January 2021

The lack of organs for transplantation is an important problem in medicine today. The growth of organs in chimeric animals may be the solution of this. The proposed technology is the interspecific blastocyst complementation method in combination with genomic editing for obtaining “free niches” and pluripotent stem cell production methods. The CRISPR/Cas9 method allows the so-called “free niches” to be obtained for blastocyst complementation. The technologies of producing induced pluripotent stem cells give us the opportunity to obtain human donor cells capable of populating a “free niche”. Taken together, these technologies allow interspecific blastocyst complementation between humans and other animals, which makes it possible in the future to grow human organs for transplantations inside chimeric animals. However, in practice, in order to achieve successful interspecific blastocyst complementation, it is necessary to solve a number of problems: to improve methods for producing “chimeric competent” cells, to overcome specific interspecific barriers, to select compatible cell developmental stages for injection and the corresponding developmental stage of the host embryo, to prevent apoptosis of donor cells and to achieve effective proliferation of the human donor cells in the host animal. Also, it is very important to analyze the ethical aspects related to developing technologies of chimeric organisms with the participation of human cells. Today, many researchers are trying to solve these problems and also to establish new approaches in the creation of interspecific chimeric organisms in order to grow human organs for transplantation. In the present review we described the historical stages of the development of the blastocyst complementation method, examined in detail the technologies that underlie modern blastocyst complementation, and analyzed current progress that gives us the possibility to grow human organs in chimeric animals. We also considered the barriers and issues preventing the successful implementation of interspecific blastocyst complementation in practice, and discussed the further development of this method.

Background: Respiratory diseases in calves are causing worldwide economic losses for the beef industry. This study was planned to determine the serum protein fractions and A/G ratio in calves with clinically diagnosed pneumonia, and evaluate the possibility uses of these parameters as clinical diagnostic parameters. Methods: The 34 calves with respiratory system problems and 10 healthy calves without clinical pneumonia symptoms were used as materials. The obtained serum samples were used for total protein and serum protein electrophoresis. Result: Albumin, α1-globulin percentages and A/G ratio decreased in the patient group (p≤0.01), other globulin fractions were higher in the patient group (p≤0.01), for % g values. According to concentration results, it was found that while albumin did not show a significant difference, α1-globulin (p≤0.05) and A / G ratio (p≤0.01) decreased in the patient group. In addition, other globulin fractions and total protein levels were higher in patient groups (p≤0.01). As a result, the serum protein fractions should be evaluated as a useful biochemical blood parameter for diagnosis and follow up of lung diseases especially in calves.

Testing the Relative Efficacies of Three Different Integrated Pest Management (IPM) Modules for Controlling Mango Mealy Bug (Drosicha mangiferae G.) at Malda, West Bengal
Authors: Nandi Partha Sarathi , Chakraborty Kaushik
Published: January 2021

Background: Mango mealy bug (Drosicha mangiferae G.) is a notorious pest of mango and when infestation reaches severity quantum fruit loss takes place. Control of this pest had been found to be impossible with conventional chemical pesticide spray. So, the urgent need is to find some non conventional management practices. Therefore, the current study was undertaken to test three different combinations of available pest management practices. Methods: To test the efficacy of the three Integrated Pest Management Modules (IPM modules) control vs. treated trees were tagged and then mango mealy bug number found in inflorescence was counted. The difference in the number of mealy bug at the peak time infestation (12 SMW) in control vs. treated trees and fruit loss reduction in control vs. treated plants gave the idea about relative efficacy of the different modules. Result: 99.46% of mango mealy bug number and 47.52% fruit drop reduction were achieved by adopting module I. Whereas up to 64.33% mealy bug and 22.84% fruit drop reduction was achieved by module II. The module III was found to be the most effective module and adoption of this module attained 54.72% fruit loss control and 97.10% mealy bug control.

Published: January 2021

Disaster induced displacement and relocation is a frequently occurring phenomenon in the Sri Lankan context. Resettlement has been recognized as a regular result of disasters such as landslides due to the large-scale property damage that occurs. This paper investigates the impact of the disasterinduced relocation process on displaced communities. The study revolves around the sub-objectives of investigating the various needs of victims in different stages of displacement and how relocation has altered the social, cultural, and livelihood dimensions of the victims. Victims of the Aranayake landslide who were residing in the Kegalle district and who were resettled mainly in a Donor Driven relocation site were selected for the study. A purposive sampling technique was implemented in two phases. In the first phase, in-depth interviews with officials and focus group interviews with community members were carried out. Next, a community needs analysis was conducted with the participation of the community and officials. The data suggests that there is a clear lacuna in strong, written policy frameworks and its practical implementation when satisfying the various needs of displaced communities. Being confined to only understanding the social and economic details of various displaced groups, policy planners have tended to neglect the necessity of conducting a needs analysis with the main reason being the lack of perception of relocation as a long-term process. Therefore, in conclusion, the study suggests a model that addresses the need for a holistic institutional arrangement with further disaster risk management strategies to address the adverse impact on the disaster-induced, displaced community.
Sociology and Medicine Interactions and Emerging Disciplines
Authors: Jayasinghe Saroj
Published: January 2021

This brief essay places the work of Professor Siri Hettige in the context of understanding of social origins of health and disease. The origin of the term â€˜social medicineâ€™ dates to the French Revolution in 1848, which called for the medical profession to integrate knowledge in medical issues, population health, social factors and public policies. During this period, similar views were expressed elsewhere e.g. in Germany by Virchowâ€™s famous statement that â€œmedicine is a social science, and politics nothing but medicine on a grand scaleâ€. In the early 20th century, another wave of social medicine originated in South America, a key figure being Salvador Allende. As the Minister of Health, he introduced these concepts to model the health services in Chile and later elected as the President. He was assassinated in a CIA sponsored military coup in 1973. In contrast, the early British and US traditions focused on a model where priority was on applying sociology in relation to individual behaviors. It was later that social structural determinants of health and diseases were addressed e.g. the Black Report of 1980. The US followed different trends, attempting to integrate concepts of the two disciplines (i.e. sociology in medicine) and studying the sociology of medicine (e.g. explaining health-seeking behaviors) and more recently, social epidemiology and politics of health. Professor Hettigeâ€™s extensive work covers almost all the above topics, trends and developments.

Authors: Dalenogare Lucas Geraldo Campos , Araújo Maria Arlete Duarte de
Published: January 2021

Este artigo tem por objetivo identificar as abordagens teóricas adotadas internacionalmente, nos últimos cinco anos, em estudos sobre Dados Governamentais Abertos. Para tanto, optou-se pela realização de uma Revisão Sistemática de Literatura, guiada pelo protocolo Kitchenham (2007). As análises abrangeram vinte e sete estudos realizados em dezenove países. Dos estudos analisados emerge a discussão de elementos teóricos acerca dos próprios dados abertos – como conceitos, requisitos, barreiras e benefícios – e de teorias associadas – como Teoria Institucional, Teoria Cognitiva, Teoria do Estado Informacional, Teoria de Ecossistemas, Teorias de Informação Interagência, da Perspectiva Multi-Nível e de Cross-boundaryou Interorganizacional, sinalizando para a ausência de uma escola de pensamento que aglutine os estudiosos do tema. Outrossim, revela-se também o potencial das políticas de dados abertos para um maior fortalecimento da democracia, geração de valor econômico, inovações e avanços técnico-gerenciais nas organizações públicas.
A Relação das Práticas do Lean Manufacturing e o Desempenho Operacional: Um Estudo no Setor de Autopeças
Authors: Vasconcellos Luis Rigato , Ferreira Fernando Coelho , Dos Santos Marcos Souza
Published: January 2021

Este relato técnico visa investigar como a adoção das práticas de lean manufacturing se relaciona com o desempenho operacional dos processos organizacionais, medido a partir do indicador OEE (Overall Equipment Effectiveness). Para o alcance desse objetivo nesse trabalho, foi conduzido um estudo de caso em uma manufatura de filtros automotivos, utilizando uma abordagem mista quali-quantitativa. A partir da aplicação de um grupo focal com seis coordenadores de produção e da análise do desempenho do indicador OEE no período de 2015 a 2017, observou-se que os processos que possuem melhor desempenho operacional são necessariamente aqueles que possuem maior grau de aderência às práticas lean. Além disso, os processos com menor grau de aderência ao lean, além de responderem pela maior parte das perdas de eficiência e de faturamento, tendem a apresentar maior variabilidade na adoção dessas práticas, quando considerados diferentes turno de trabalho.

Published: January 2021

A utilização de tecnologias em serviços bancários aumentou de forma significante nos últimos anos e impacta de diferentes formas a vida social dos indivíduos e, embora ofereça muitos benefícios, traz consigo diversos fatores que afetam o comportamento e o estilo de vida. Neste contexto, os efeitos dessa tendência ainda não são conhecidos de forma clara pela literatura e os resultados são conflitantes, o que demanda estudos que busquem analisar fatores demográficos, comportamentais e sociais. Nesta via, este estudo de natureza quantitativa, descritiva e documental busca identificar que fatores apresentam maior impacto no uso do mobile banking para movimentações financeiras. Os resultados obtidos por meio da técnica de Regressão, analisados por meio do software SPSS, versão 22, apontam que indivíduos com níveis de escolaridade mais alto utilizam mais o serviço mobile banking em relação à indivíduos com níveis mais baixos de escolaridade.
Avaliação do aprendizado na produtividade em obras de montagens industriais eletromecânicas: abordagem por meio de dinâmica de sistemas
Authors: Torres Antonio Fabio Guimarães , Ferreira Wanyr Romero , Bahia Eduardo Trindade
Published: January 2021

A otimização da produção é o foco principal das grandes indústrias, sendo assim, para aumentar a produtividade, o setor de montagens eletromecânicas precisa romper barreiras difíceis, como a falta de mão de obra com qualificações adequadas no local ou região da obra, e a disputa pelos melhores profissionais especializados no setor de infraestrutura. Buscou-se, neste trabalho, estudar a influência do aprendizado da mão de obra na formação da memória de conhecimento e no desempenho da organização em obras de montagens eletromecânicas industriais. Para tal, desenvolveu-se um modelo de dinâmica de sistemas para simular o comportamento dinâmico da produção, da força do trabalho e da produtividade. Os resultados mostraram que a transferência do aprendizado assim como o aprendizado adquirido, podem melhorar a produtividade, consequentemente os resultados esperados pela obra em questão, mostrando possibilidade de análise futura da tendência ao que poderá acontecer no quesito produtividade sobre a influência do aprendizado.

O objetivo do presente trabalho é analisar a volatilidade e rentabilidade do bitcoin em comparação com três carteiras de ativos de ações que apresentaram excelente grau de avaliação ao longo do período analisado. Desde o inicio do ano de 2017, verificou-se o aumento do valor do bitcoin, obtendo o valor de USD 13.411,00 em 31 de dezembro de 2017. A supervalorização repentina e o aumento no número de usuários despertaram os analistas, Estados e investidores a observar a questão da volatilidade da moeda. Observou-se o período de 2015 a 2017 para o calculo da volatilidade dos ativos. Este estudo reuniu informações tratadas através do método quantitativo e de uma pesquisa de campo. Decidiu-se utilizar como técnica o modelo autoregressivo AR(p), buscando-se o retorno através da média incondicional AR(p), e da variância incondicional ARCH(p) ou EGARCH (p,q). Os resultados obtidos revelaram o grau de conhecimento dos participantes em relação a aplicações financeiras, a um possível perfil para investidores em bitcoin, a rentabilidade e a volatilidade dos ativos comparados, possibilitando analisar a diferença do bitcoin com outros ativos de renda variável.
Um estudo dos fatores críticos de sucesso em projetos de TI gerenciados por abordagens ágeis em uma instituição financeira
Authors: Martins Alvarez Fernandes Pedro Jose , Rabechini Jr. Roque
Published: January 2021

Considerando a inconstância da taxa de sucesso dos projetos, sabe-se que as técnicas e ferramentas pertencentes às abordagens de gerenciamento de projetos, exercem influência no resultado destes, assim como a existência de casos de fracasso cuja principal causa é a incorreta utilização das práticas dessa área de conhecimento. Com o intuito de aumentar ou estabilizar a taxa de sucesso dos projetos, muitas empresas estão adotando a abordagem ágil, como alternativa à abordagem tradicional. No entanto, a relação entre a abordagem ágil e o sucesso de projetos é um fenômeno que não está consolidado na literatura especializada em gestão de projetos. Visando entender esse fenômeno, o objetivo deste estudo foi avaliar os fatores críticos de sucesso dos projetos de tecnologia gerenciados por abordagem ágil em uma grande instituição financeira, analisando se os fatores identificados na literatura seriam suficientes para garantir o sucesso de tais projetos, assim como classificar os fatores críticos identificados em ordem de importância. A metodologia utilizada foi um estudo de caso com abordagem exploratória. Como resultado, foi possível verificar que os fatores identificados na revisão teórica são relevantes para o sucesso de projetos gerenciados por abordagem ágil, porém há a necessidade de agregar o controle das variáveis custo e escopo aos fatores identificados previamente. Ademais, identificou-se que os fatores envolvimento do cliente e estratégia de entrega, classificados na literatura como dois dos principais benefícios da abordagem ágil, foram classificados neste estudo como os fatores menos relevantes.
