En el modelo A, la tasa de inflación es un promedio ponderado de la tasa de variación en los salarios y de la tasa de variación equivalente en moneda nacional de los precios externos cuya dinámica está principalmente determinada por el tipo de cambio. En el modelo B, la tasa de inflación es igual a la tasa de variación del tipo de cambio y de los precios externos. Se presentan estimaciones en ambos modelos, de los cuales además se utilizan la tasa de inflación de México. El modelo A es superior al modelo B desde el punto de vista econométrico.
EVALUATING EFFICACY OF CYTOLOGICAL DIAGNOSIS OR SEROUS EFFUSIONS BY SMEAR CYTOLOGY AND CELLBLOCK TECHNIQUE
Authors: Priya Kirti , Bharti Sujeet Kumar
Published: May 2021

Introduction :- Cytological examination of serous effusions is of paramount importance not only for
diagnosing cancer, but it may also reveal information regarding various inammatory conditions,
parasitic infestations, infection with bacteria, fungi or viruses, and some immunological diseases. Cellblock technique has
many advantages over conventional smear cytology in improving the sensitivity of diagnosis. The main advantages of the
cellblock technique are preserving tissue architecture and obtaining multiple sections from the same material for special stains
and immunohistochemistry.
Objectives :- To study the body uids, i.e., pleural, peritoneal, and pericardial, for the absence of local or systemic pathological
situation. To evaluate the diagnostic efcacy of a combined approach of conventional smear study and cellblock technique in
serous effusions.
Methods:- A total of 100 uid samples from referral centers received in the Cytology section, After preparing two conventional
smears for PAP and Giemsa stains, the residual sample was subjected to cellblock preparation. Nathan's Alcohol Formalin
Substitute was added and xed for an hour. After xation, the specimen was centrifuged at 1500 rpm for 15min.The supernatant
was decanted, and the sediment completely drained off by XIinverting tube over Whatman lter paper. After discarding the
supernatant xative, the pellet formed was removed with a pointed spatula and placed on top of the lens paper inside the tissue
cassette, and processed for parafn embedding.
Results:- In the total of 100 samples were subjected for cytological evaluation. Pleural uids were 47%, peritoneal uids were
43%, and pericardial uids were 10%. Maximum samples were in age group of 41-50 years. By Conventional smear cytology,
benign, suspicious and malignant lesions were 76%, 14.5%, and 9.5%, respectively. By cellblock study, benign and malignant
lesions were 75.5% and 24.5%, respectively.
Conclusion:- Morphological features were better appreciated by cellblock composition, which risen the sensitivity of cyst
diagnosis hence serves as a useful adjunct to conventional smears.
OUR SURGICAL EXPERIENCE IN ACUTE MESENTERIC ISCHEMIA- VARIOUS PATHOPHYSIOLGICAL TYPES – A CASE SERIES
Authors: Santhi B. , Ramprasath A. , Saradha R.
Published: May 2021

BACKGROUND: Mesenteric ischemia is a frequently lethal condition resulting from critically reduced
perfusion to the gastrointestinal tract. It accounts for 1-2% of hospital admissions for abdominal pain.
Mortality due to mesenteric ischemia ranges from 24% to 96% with an average of 69%.
AIM: The aim of this case series is to outline the clinical presentation and challenges in diagnosis of acute mesenteric ischemia
and emphasize the importance of early diagnosis and intervention in reducing the mortality and morbidity. This article
presents a series of 4 cases of the 3 major types of acute mesenteric ischemia – 2 cases of Acute Mesenteric Arterial
Thrombosis(AMAT), one case of Acute Mesenteric Arterial Embolism(AMAE) and one case of Mesenteric Venous
Thrombosis(MVT).
MATERIALS AND METHODS: A total number of 4 patients who had undergone emergency laparotomy for acute mesenteric
ischemia during the month of December 2020 in the Department of General Surgery, Government Kilpauk Medical College
were studied. All 4 cases have been analysed during this study period of one month and followed up until discharge from the
hospital.
RESULTS: This case series consisted of 4 cases. Out of 4 cases, 3 were cases of Superior Mesenteric Arterial Occlusion due to
thrombus and emboli and 1 was a case of Superior Mesenteric Vein Occlusion by thrombus. All 4 were male patients. All 4
patients presented with sudden onset of abdominal pain with or without vomiting. Abdominal distension, constipation and
clinical features suggestive of bowel gangrene was not seen in all cases. Out of 4 cases, 2 cases were diagnosed early and
taken up for immediate surgery and had a better outcome postoperatively with shorter hospital stay. Denitive diagnosis could
not be made at time of admission for one case and was taken up for surgery late after the general condition of the patient
deteriorated and extensive gangrene of the small bowel was seen during surgery. One case succumbed to septic shock after
surgery following delayed presentation. This case series attempts to highlight that the key to successful management in acute
mesenteric ischemia is a high index of suspicion leading to early diagnosis, aggressive resuscitation and early mesenteric
revascularization.
CONCLUSION: Despite the remarkable advances in in vascular surgical technique, vascular imaging, percutaneous
intervention and surgical critical care, mesenteric ischemia remains a complex and often disheartening disease. Acute
mesenteric ischemia is a life threatening vascular emergency that requires a high degree of clinical suspicion and early
intervention to avoid a poor outcome. As Acute Mesenteric Ischemia often affects elderly patients, we have to consider the
possibility of acute mesenteric ischemia in all elderly patients presenting with abdominal pain that is out of proportion to the
ndings on physical examination
STUDY OF OCCURRENCE OF THE ANTERIOR TUBERCLE IN THE MARGIN OF THE OCCIPITAL FORAMEN IN BIHAR STATE REGION
Authors: Hussain Md. Zahid , Singh Vijay Kumar , Kumar Subodh
Published: May 2021

Background: The presence of structures that pass along the anterior margin of the occipital foramen
interposed between the basilar part of the occipital and the atlas may reduce the circumference of the
foramen causing compression of the spinal cord and leading to signs and symptoms of neurological decits due to its
asymmetry. The aim of this study was to determine the incidence of anterior tubercle at the occipital foramen margin. Out of 50
skulls, 2 (4%) skulls shows occurrence of the anterior tubercle in the margin the occipital foramen/foramen magnum with
different antero-posterior and transverse measurement . Tubercle was found in the anterior margin of the occipital foramen in
2 (two) skull, The incidence of occipital tubercle, probably formed by the apical ligament exostosis of the dens, was 04 %. In 1st
case the tubercle had a triangular shape, was situated at the midpoint of the anterior margin of the foramen, with its apex
facing back toward the occipital foramen and measuring about 4mm in the antero-posterior direction and 3 mm in the
transverse. In 2nd case a pyramidal projection was found at the anterior margin of foramen magnum, with the apex directed
backwards towards the posterior margin of foramen magnum. The tubercle measured 3.5 mm antero-posteriorly and 2mm
transversely. The knowledge of the presence of the occipital tubercle is of great clinical importance, as it may lead in many
cases to compression of the neurovascular structures.

patients presenting with acute cerebellar infarction. A total of 45 patients (male-34; female- METHODS:
11) admitted with acute cerebellar infarction (ischemic) in our hospital during December 2019 – December 2020, were analyzed
prospectively. We analyzed the clinical presentation, radiological investigation, associated co-morbid illness and the clinical
outcome following various management strategies. 30 patients were managed conservatively, out of whi RESULTS: ch 25
patients survived and 5 patients expired. 8 patients were managed with ventricular drainage alone. 6 of them improved,
whereas 1 patient expired. 7 patients needed sub-occipital decompressive craniectomy and removal of infarct in our study. 2 out
of 7 patients survived and the rest died. Overall mortality in our series was 14.6%. The management criterion CONCLUSION:
mainly depends on periodic clinical & radiological evaluation. Even though, the optimal timing and surgical methods remains
controversial. Ventricular drainage alone can be reserved for patients with ventricular dilatation & sub-occipital decompressive
craniectomy with or without EVD can be advocated for those with acute deterioration with brainstem compression.
MACHINE LEARNING BASED CLINICAL DECISION SUPPORT SYSTEM TO PREDICT FETAL HYPOXIA IN WOMEN DURING ANTENATAL CHECK-UP.
Authors: Baxi Sajal
Published: May 2021

BACKGROUND:Most under-five deaths occur within the first month after birth and intrapartum complications are a
major contributor to the cause of death. These defects can be easily identified during the ante-natal check-up by use of a
non-stress test. Due to the lack of availability of resources and medical experts in remote areas clinical decision support
systems powered by machine learning models can provide information to the healthcare provider to make timely and
better-informed decisions based on which course of treatment can be planned.
AIM:The study aims to develop an accurate and sensitive clinical decision support system model that can identify
pathological fetuses based on the fetal heart rate recordings taken during the non-stress test.
METHOD: Foetal Heart rate recordings along with 10 other variables were collected from 1800 pregnant women in their
third trimester. The data was put through a feature selection algorithm to identify important variables in the set. The data
set was randomly divided into 2 independent random samples in the ratio of 70% for training and 30% for testing. After
testing various machine learning algorithms based on specificity, sensitivity to accurately classify the fetus into normal,
suspected, or pathological Random Forest algorithm was chosen.
RESULT:The fetal status determined by Obstetrician 77.85% observations from the normal category, 19.88% from the
suspected category, and 8.28% from the pathological category. The Boruta algorithm revealed that all 11 independent
variables in the data set were important to predict the outcome in the test set. In the training set the model had an
accuracy of 99.04% and in the testing set accuracy was 94.7% (p-value=< 2.2e-16) with the precision of 97.56% to detect
the pathological category.
CONCLUSION:With the ability of the model to accurately predict the pathological category the CDS can be used by
healthcare providers in remote areas to identify high-risk pregnant women and take the decision on the medical care to
be provided.

A novel optimization approach for sub-hourly unit commitment with large numbers of units and virtual transactions
Authors: WU JIANGHUA , Luh Peter , Chen Yonghong , Bragin Mikhail , Yan Bing
Published: May 2021

Unit Commitment (UC) is an important problem in power system operations. It is traditionally scoped for 24 hours with one-hour time intervals. To improve system flexibility by accommodating the increasing net-load variability, sub-hourly UC has been suggested. Such a problem is larger and more complicated than hourly UC because of the increased number of periods and reduced unit ramping capabilities per period. The computational burden is further exacerbated for systems with large numbers of virtual transactions leading to dense transmission constraints matrices. Consequently, the state-of-the-art and practice method, branch-and-cut (B&C), suffers from poor performance. In this paper, our recent Surrogate Absolute-Value Lagrangian Relaxation (SAVLR) is enhanced by embedding ordinal-optimization concepts for a drastic reduction in subproblem solving time. Rather than formally solving subproblems by using B&C, subproblem solutions that satisfy SAVLR’s convergence condition are obtained by modifying solutions from previous iterations or solving crude subproblems. All virtual transactions are included in each subproblem to reduce major changes in solutions across iterations. A parallel version is also developed to further reduce the computation time. Testing on MISO’s large cases demonstrates that our ordinal-optimization embedded approach obtains near-optimal solutions efficiently, is robust, and provides a new way on solving other MILP problems.

Government regulations impose physical distancing for all students. Students and workers are required to stay at home. At SD Negeri Pedurungan Kidul 02 Semarang, they must comply with the regulations that apply during the pandemic. This has resulted in the emergence of several difficulties for work that must be carried out online. One of them is in education, and a teacher must be able to carry out teaching activities online. This can be considered a major obstacle for a technology-blind teacher so that the delivery and evaluation of the material cannot be conveyed properly. Some teachers need additional skills regarding the use of technology to help implement online teaching from the above problems. The implementation of this socialization is focused on conducting evaluations with online media using the google form application, google sites, google Lens, google expedition AR and VR. The implementation of this activity has received a positive response from the participants. This result can be seen from the questionnaire results obtained by the pre-test and post-test for each PKM training and mentoring participant question, which has increased from 28.58% to 91.55% for Yes questions. Thus this training can increase the ability to use and utilize Google's features.
A KNOCK AROUND THE ECONOMIC IMPACT OF COVID-19 WITH REFERENCE TO THE QUANTUM OF GOODS AND SERVICES TAX COLLECTION IN INDIA
Authors: Dr. Baneswar Kapasi  , Dr. Mahesh Kumar Kurmi
Published: May 2021

COVID -19 has wedged all the major economies across the globe significantly. The World Health Organisation (WHO) first declared COVID-19 as a world health emergency in January 2020. The virus originated in Wuhan, China, but has been detected in over 200 countries. Amid the Coronavirus Pandemic, several countries worldwide resorted to lockdown to control infection. Due to lockdown, the production and distribution chains have been disrupted across the lands. All the segments of the economy have been impacted in different magnitude, and this has a direct impact on GDP, unemployment ratio, and tax collection. Goods and Services Tax (GST) is a harmonized tax of different indirect taxes in India. The GST collection reflects the volume of economic activities in India. Thus, in this paper, an attempt has been made to assess the impact of Covid-19 on the Indian economy concerning the quantum of Goods and Service collection in Indian during the lockdown period. For this study, secondary data relating to GST collection have been pooled from the official websites of the GST Council of India for the last three years, i.e., 2018 to 2020, and pair t-test have been run for testing statistical significance of the impact of COVID-19 on the quantum of the collection of Goods and Service Tax in India before and after lockdown announcement after adjusting the inflation factor. The results indicate no significant difference in the quantum of Goods and Services Tax Collection in India before and after the lockdown announcement due to the COVID-19 outbreak but a loss of Rs. 1,41,837 crore owing to the low collection of GST from March 2020 to August 2020 gives us a clear message that we should undoubtedly rethink the plans in more structural and more viable ways to reach a position to absorb any kinds of uncertain threats from the external environment.

Economic crisis caused by COVID-19 pandemics: predictions, prognoses, and mitigation measures
Authors: Davymuka Stepan A. , Fedulova Lyubov I.
Published: May 2021

The approaches of economists, experts, and international expert organizations regarding the prediction of pandemics emergence and prognosis options of economic development in the crisis period are outlined. The paper substantiates the conclusion that despite the previous lessons, numerous predictions, and warnings of experts on the inevitability of economic crisis in the nearest future, the crisis was “unexpected” and the world, not only Ukraine, turned out to be unprepared again. Meanwhile, the so-called catalyzer of changes in the economy – the coronavirus pandemics – turned out to be an important factor. The pandemics has emphasized the systemic problems of both global development and the economy in Ukraine. It has displayed the need to take immediate efficient and real measures in healthcare and economic policy, including global cooperation to overcome its consequences, protection of the vulnerable segments of the population, and strengthening the security system of the countries in terms of operative response and prevention of similar events in the future. The official governmental programs and practices of countries in the world and Ukraine on the support of business and citizens being in difficult circumstances because of coronavirus are analyzed, and the peculiar trends of the process are determined with further definition of the most optimal and perspective examples (lessons) for further application in selection and implementation of mechanisms to fight the economic crisis and its consequences. The paper proves that each country has prepared and continues adjusting its model of anti-crisis activities to minimize economic losses from the COVID-19 coronavirus pandemics and global economic recession based on their priorities and available resources. The practice has shown that Ukrainian officials do not act within the distinct strategy and dwell on the mechanical reproduction of the steps of other countries in form of chaotic and unreasonable actions, and even more so – declarations. The estimations regarding the nature of the impact of the scales of economic activity restrictions on various economic sectors are constantly changing, preventing the opportunity of reliable prognoses because the pandemics hasn’t disappeared anywhere and uncertainty and threats are still essential.
Substantiation of strategic directions and structural results of reforming the economy of Ukraine
Authors: Rushchyshyn Nadiya M.
Published: May 2021

The strategic directions of reforming the economy of Ukraine are analyzed. The author defines the main reasons for the existence of structural imbalances, including limited resources (material, intellectual, financial, investment, innovative); reduction of innovative production; high material and energy intensity of production; a high share of intermediate structure of GRP, which shows a limited production of goods and services with a high share of GVA; low development of innovation infrastructure. The paper proves that the real sector of the economy is in a state of deindustrialization and needs to restore technological, scientific, intellectual, and export capacity. As a result, the author has focused attention on the necessity of systemic reforms in a number of areas, which should become the basis for the dynamic socially-oriented development of Ukraine. The most important reforms include the technological modernization, reindustrialization, increase of high-tech exports, systemic de-shadowing and formation of a competitive environment, business development, expansion of the middle class, modernization of social security and investment attractiveness, development of strategic industries, domestic market development, resource sector growth, and energy efficiency. The structural results of reforming the economy of Ukraine are summarized and indicators that will represent the efficiency of changes in each of the reformed basic areas are identified. For example, the efficiency of the reforms implementation in the social sphere will be displayed by the growth of incomes and the level of life quality and well-being of the population. In the field of education, such results will be summarized by increasing the quality and competitiveness of education, its harmonization with the needs and demands of professionals in the labor market. In the field of healthcare, the changes will be displayed in the creation of a modern reformed health care system with a high level of quality and accessibility of medical services. The decrease of migration activity processes is defined as the main result of the development of the internal labor market.

Published: May 2021

Analysis and consideration of current migration trends in our country, in particular mass interstate migration movements in the context of Ukraine's participation in the European and world migration space, are considered among the important factors in shaping its national policy. Educational migration is a special threat to the socio-economic development of the country and sustainable development of society, as the formation of highly qualified personnel, accumulation of intellectual capital, and increasing scientific and technological potential of the country are among the important factors of economic and social progress. Due to the intensification of interstate migration flows and the development of the quality of the higher education system in foreign educational institutions, migration for education takes a larger share, which is mostly accompanied by constant migration and departure of Ukrainian citizens for permanent residence abroad. The analysis of publications on this issue proves the urgency of educational migration research, and today it remains important to analyze trends in educational migration, find mechanisms to counter the transformation of Ukraine into a country of origin of educational migrants, as well as their repatriation. The article analyzes the educational migration processes in Ukraine in the regional context. The main regional centers of higher education are identified. The focus is on the migration intentions of the population to study abroad and a comparative description of the educational systems of different countries. The order and stages of the admission campaign in foreign educational institutions are described. The essence and features of educational migration are studied and the main reasons that help Ukrainian students to choose foreign higher education institutions are highlighted. The main causes and consequences of educational migration, as well as potential opportunities for educational migration, are identified. Certain benefits and costs associated with educational migration processes are justified. The directions of development of educational migration and effective migration system in Ukraine and its regions, which should take a worthy place in the migration policy of the state, are offered.

The article summarizes the arguments and counter-arguments within the scientific discussion on regulating the development of professional competence of trade workers, as the transformation processes taking place in the context of globalization and European integration put forward new requirements for personnel management at micro and macro levels. This is due to the fact that in the conditions of market development, the most significant transformations take place in the social and labor spheres. The main purpose of the article is to study the state and trends of trade in the context of ensuring the professional competence of employees. Systematization of literature sources and approaches to solving the problem of professional competence of trade workers shows that Ukrainian and foreign scientists have studied professional competence, but in modern conditions, there is a need for critical analysis of trade status and trends in the context of professional competence. The study of this issue was carried out in the following logical sequence: determining the results, forming the main tasks and areas of research on the main indicators of trade, and identifying trends in trade in the context of ensuring the professional competence of employees. The methodological tools of the study include the system of economic laws, concepts, and categories, and the fundamental provisions of modern economic theory and applied economics. An abstract-logical complex approach and methods of analysis and synthesis are the general methodological basis of the research. The trade indicators and trends in their development constitute the object of the study as they contribute to ensuring the professional competence of workers in this industry. The article examines the indicators of the condition and trends of trade and their impact on ensuring the professional competence of employees. The demand for specialties that can be realized in the longer professional activity in trade is investigated. A characterological table of general and professional competencies of management staff and salespeople depending on positions is developed.

5-year Progression of CADASIL: A Case Report
Authors: Loh Hong Chuan , Yuen Kah Hay , Looi Irene
Published: May 2021

A female patient in her 40’s of mixed Chinese-Indian ancestry was referred to our neurology clinic for frequent migraine with aura and CADASIL. She had been treated for acute encephalopathy in 2014. The incident led to her CADASIL diagnosis and later retinitis pigmentosa, both rare conditions. Initial clinical assessment showed moderate severity of migraine and normal cognitive function. As there is no specific treatment recommended for CADASIL, the patient was maintained on pharmacological therapies for secondary prevention of ischaemic stroke, treatment of seizure, symptomatic treatment for migraine and a cholesterol-lowering drug. A supplement containing Vitamin E (tocotrienols) was recommended. During the ensuing 5-years, there were no further neurovascular incidents and her migraine went into full remission.

Published: May 2021

Neste trabalho, apresentamos uma experiência de Formulação de Problemas em Matemática para os estudos de Função Afim, que ocorreu em uma turma de 1ª Série do Ensino Médio, de uma Escola Pública Estadual, no município de Marataízes – ES. De natureza qualitativa, os dados foram produzidos no decorrer da etapa de regência do Estágio Supervisionado III, do Curso Superior de Licenciatura em Matemática do Instituto Federal do Espírito Santo (Ifes), Campus Cachoeiro de Itapemirim – ES. Os estudantes foram convidados a formularem problemas que contemplassem a Lei de Formação de uma Função Afim. A análise dos dados nos permitiu concluir que a Formulação de Problemas reforçou o protagonismo discente nas aulas de matemática, propiciando o desenvolvimento da argumentação e do pensamento crítico, importantes na aprendizagem, e permitiu revelar preferências, saberes e vivências dos estudantes nos problemas formulados, gerando motivação em matemática.

Este artigo objetiva discutir a percepção dos professores de Matemática em relação à própria formação acerca da inclusão de pessoas com deficiência e as contribuições da disciplina Laboratório de Recursos Didáticos no processo de formação, no que se refere: 1) a percepção de licenciandos sobre o espaço de discussão da temática; 2) a contribuição da disciplina de Laboratório de Recursos Didáticos na formação inicial do professor de Matemática. A pesquisa qualitativa de estudo de caso teve como instrumentos de coleta de dados, questionário, tarefa e planejamento realizados pelos licenciandos. Os dados foram analisados por meio da Análise de Conteúdo. Os resultados demonstram que o espaço de discussão sobre o ensino e a aprendizagem de alunos com deficiência durante a formação inicial ainda é incipiente, a indicar que a principal colaboração da disciplina se refere à proposição de planejamento por parte dos licenciandos de tarefas matemáticas inclusivas. Com isso, aponta-se para a urgência de a temática fazer parte da formação inicial de professores a contemplar mais práticas pedagógicas inclusivas.

Published: May 2021

Este artigo apresenta um mapeamento de pesquisas brasileiras que propõem e analisam a utilização de Jogos e/ou Materiais na formação inicial de professores de Matemática, buscando responder à questão: “Como se caracteriza a produção acadêmica que tem como foco a utilização de Jogos e Materiais no contexto da formação inicial de professores de Matemática?”. Esta pesquisa, do tipo Estado da Arte, tem como corpus de investigação sete trabalhos do Catálogo de Teses e Dissertações da (CAPES), organizados em três categorias: Práticas formativas, Práticas formativas/educativas e Pesquisa documental. Esta investigação constitui uma das fases de uma pesquisa de mestrado em andamento e possibilitou reconhecer os Jogos e Materiais como uma alternativa de mudança da prática pedagógica docente, capaz de contribuir para a aprendizagem dos alunos da educação básica. Contudo, o mapeamento indica lacunas a serem estudadas acerca das propostas com Jogos e Materiais, nas práticas e orientações curriculares das instituições formadoras.

Published: May 2021

Esta investigação teve como objetivo compreender as concepções iniciais acerca do planejamento de uma aula com o uso de Tecnologias de Informação e Comunicação (TIC) de licenciandos em Matemática na Prática enquanto Componente Curricular (PeCC III). A partir do estágio de Docência no Ensino Superior, foi desenvolvida uma Investigação-Ação numa perspectiva da reflexão crítica e pesquisa da própria prática. Para tal, utilizou-se a prática da escrita e reescrita, pois acredita-se que permite aos licenciandos evoluir conceitualmente, favorecendo o desenvolvimento profissional além de propiciar a investigação e a reflexão da prática docente. Utilizou-se como abordagem metodológica a pesquisa qualitativa, com análise dos processos de escritas narrativas de 26 licenciandos. Pela análise temática de conteúdo das escritas dos licenciandos identificou-se três categorias: i) concepção inicial de planejamento; ii) descrições a priori de como realizariam o planejamento de uma aula (com TIC); iii) descrições a posteriori de como realizaram o planejamento de uma aula com TIC. Portanto, foi possível perceber o potencial desta investigação para a constituição dos conhecimentos de professor no que tange aos sentidos atribuídos pelos licenciandos no planejamento de uma aula.
