Los “años perdidos” en la historia del Sistema Nacional de Salud del Perú
Authors: Domínguez-Barrera Constantino
Published: March 2021

Estimado editor:
En el contexto actual de la pandemia por COVID-19, las discusiones y opiniones en relación a la salud pública del Perú son abordadas ampliamente por los medios de comunicación. De este modo, un canal nacional de televisión, en uno de sus programas llamado “El país que cuidamos ¿Cómo lograr un acceso universal a la Salud en el Perú?”, compartió la opinión de un reconocido médico, quien consideró al período 1960-1990 como “años perdidos” en la historia del Sistema Nacional de Salud (SSS) del Perú. Esto evidencia la necesidad de verificar la información que se brinda a la población, ya que, como expongo a lo largo de esta carta, en realidad en ese lapso se alcanzaron importantes logros en lo que respecta al SSS peruano que no están siendo reconocidos por dicho profesional.

Published: March 2021

Introduction: Gitelman syndrome is a rare hereditary primary renal tubular disorder, with a prevalence of approximately 1 to 10 cases per 40 000 people. It does not have specific symptoms, so its diagnosis depends on high clinical suspicion by the treating physical and a sequential approach to hypokalemia, especially in young patients. Thus, a diagnostic algorithm is proposed at the end of this report.
Case presentation: A 23-year-old woman with a history of hospitalization due to hypokalemia presented to the emergency service with intermittent cramping in her lower limbs, which was exacerbated by gastrointestinal symptoms. Laboratory tests reported the following findings: metabolic alkalosis, elevated levels of potassium, magnesium, chloride and sodium in urine, and reduced levels of calcium in urine. Thus, potassium supplementation and eplerenone administration were started, obtaining the complete resolution of symptoms. At her last follow-up appointment, the patient was asymptomatic, and her serum electrolyte levels were normal. In addition, during her hospital stay and due to the high suspicion of Gitelman syndrome, a genetic study was performed, which reported a mutation of the SCL12A3 gene, confirming the diagnosis.
Conclusion: The sequential approach to a patient with recurrent hypokalemia is very important to reach an accurate diagnosis among a wide range of differential diagnoses.

Published: March 2021

Introduction. This paper analyzes the problem of formation of educational Internet resources. Despite numerous works concerning the importance of using information technologies in the education, the issue of its rational organization remains understudied. The purpose of the article is to analyze what patterns are observed when students read educational information from the screen, and how these patterns can be used to create educational Internet resources. Materials and Methods. To study the interaction of students with educational information on the screen, the authors used the method of oculography. The results were processed using the BeGaze and IBM SPSS Statistics 22 programs. In total 100 respondents participated in the experiment, 50 of which were trained in the natural sciences, 50 – in the humanities. Results. It is determined that the presence of media text influences the oculomotor activity of students: students commit fewer fixations and saccades, the average duration of saccades increases, the value of the Scanpath Length indicator decreases. It was revealed that the orientation of training forms strategies for working with information on the screen: students of natural sciences read texts longer, blink less often; they have a higher Scanpath Length value. When forming educational Internet resources, the developer should take into account the students’ specialisms with reference to e-material. It should also be borne in mind that the presence of images on educational Internet pages is perceived by students as a simplifying factor for completing the cognitive task of reading, but students practically do not pay attention to the images themselves. This may be attributed to the specificity of the learning process, when their main focus is on written texts acquisition. Discussion and Conclusion. The results of the study open a new direction in the study of the problem of rational organization of the student's learning process using technical devices and may be of interest to developers of educational Internet resources, as well as practicing teachers.
Socio-Psychological Predictors of Successful Integration of Institutionalized Adolescents into Mainstream Schools
Authors: Bakhvalova Elena V. , Miklyaeva Anastasia V.
Published: March 2021

Introduction. The study sought to reveal socio-psychological factors of successful integration of institutionalized adolescents into mainstream schools. The relevance of the research is determined by the necessity to spread practices of integrating institutionalized children and adolescents into mainstream schools to expand their social experience.
Materials and Methods. The purpose of the study was to explore the socio-psychological predictors that determine the successfulness of integration of institutionalized adolescents into mass secondary schools. Among the sociopsychological predictors of integration success, we analyzed the communicative characteristics of adolescents and the specifics of their relations with other subjects of the educational process. The study involved 678 people including students of secondary schools with integration programs, their parents and teachers. The empirical data were collected through questionnaires, expert survey of teachers, and projective drawing with subsequent expert evaluation of the results, as well as testing, including M. Kondash’ Anxiety Scale (to assess the adaptation of orphaned children in school), S. Bratchenko’s methods “Direction of the personal communication”, M. Snyder’s Diagnostics of communicative control (to assess their communicative potential) and J. Moreno’s Sociometry (to assess their place in the system of interpersonal relations with classmates).
Results. The results show that about one out of ten institutionalized adolescents successfully integrates into the educational process of mainstream schools, while the others experience difficulties in this process. Significant predictors of successful integration are indicators that characterize the communication skills of institutionalized adolescents, as well as their relationships with “adult” subjects of the educational process (primarily, parents of classmates). The most favorable conditions for the successful integration of institutionalized adolescents into mainstream schools are associated with the first stages of their attendance at a mainstream education institution.
Discussion and Conclusion. The findings contribute to social and educational psychology and can be used to develop scientifically-based system of social-psychological support of integration of institutionalized adolescents into mainstream schools, the targets which should be aimed at the development of communicative skills of institutionalized adolescents, and also on formation of system of their relations with other subjects of educational process.
Chemometric approach to quality characterization of milk-based kombucha beverages
Authors:   University of Novi Sad, Faculty of Technology Novi Sad, Bulevar cara Lazara 1, 21000 Novi Sad, Serbia, Vitas Jasmina
Published: March 2021

Milk-based kombucha beverages were obtained conducting kombucha lead fermentation of milk. In order to discriminate the analysed samples and to detect similarities or dissimilarities among them in the space of experimentally determined variables, hierarchical cluster analysis (HCA) and principal component analysis (PCA) were applied. Linear discriminant analysis (LDA) was conducted on the raw data set in order to find a rule for allocating a new sample of unknown origin to the correct group of samples. In the space of the variables analysed by HCA, the dominant discriminating factor for the studied samples of kombucha beverages is the milk fat (MF) content, followed by total unsaturated fatty acids content (TUFA), monounsaturated fatty acids content (MUFA) and polyunsaturated fatty acids content (PUFA). The samples with 0.8 and 1.6% milk fat belong to the same cluster in the space of the analysed variables due to similarities in their AADPPH. It was determined by LDA that there was the biggest difference in quality between the groups of products with winter savoury and stinging nettle, while the highest similarity is between groups of products with wild thyme and peppermint regarding their pH values and antioxidant activity expressed as AADPPH.
A comparison between Polish Holstein-Friesian and F1 hybrid Polish Holstein Friesian × Swedish Red cows in terms of milk yield traits
Authors:   Warsaw University of Life Sciences, Institute of Animal Sciences, Department of Animal Breeding, Ciszewskiego 8, 02-786 Warsaw, Poland, Solarczyk Paweł
Published: March 2021

The intensive breeding work of Holstein-Friesian cattle has led to the decrease in the diversity within the population and to inbreeding depression, which may impair its functional traits. In addition, as shown by the research, production traits are negatively correlated with functional traits such as reproduction, health, and longevity, which have a very strong impact on the profit of dairy farms. The aim of this study was to compare milk yield traits of hybrids obtained by crossbreeding of Polish Holstein Friesian (PHF) cows and Swedish Red (SRB) bulls with values obtained for pure PHF cows. For the study, 100 primiparous cows were selected and divided into two groups. The experimental group consisted of 50 crossbreds (PHF×SRB), while the control group consisted of 50 purebred PHF cows. The study showed a higher content of milk components (fat by 11.78%, protein by 9.06%, dry matter by 5.75%) in PHF×SRB, as compared to PHF. A lower level of SCC (by 38.94%) has also been shown in hybrids, which indicates their higher resistance to udder diseases. The experiment demonstrated a highly significant impact of heterosis on performance parameters and technological quality of milk in F1 generation obtained as a result of crossbreeding between PHF cows and SRB bulls.

The present study assessed the sensory impact of potatoes biofortification with iodine and the stability of iodine during six months of storage. Four biofortified cultivars (Cupido, Marabel, Orchestra and Universa) and their controls (non-biofortified) were evaluated. The present study assessed the sensory impact of potatoes biofortification with iodine and the stability of iodine during six months of storage. Four biofortified cultivars (Cupido, Marabel, Orchestra and Universa) and their controls (non-biofortified) were evaluated. Descriptive analysis was applied with a panel to describe the sensory properties, and triangle tests were applied with consumers to evaluate perceivable differences between controls and respective biofortified samples at the end of shelf life. Iodine content was quantified on raw potatoes for three periods of storage. Descriptive analysis showed some differences between controls and iodine-biofortified samples, especially in texture (hardness). However, consumers did not significantly discriminate fortified from unfortified samples. Iodine was stable during storage in all varieties. Orchestra cultivar showed the highest iodine content, while Universa the lowest.
An axiological approach to the problem of sexual education
Authors: Bobko Aleksander
Published: March 2021

Among all sorts of technological and cultural breakthroughs affecting our civilisation which we have witnessed over the last few decades, the changes regarding the most intimate spheres of human nature, those of sexuality, may have passed unnoticed. A series of changes in social norms triggered after 1968 resulted in a situation which, as far as sexuality is concerned, can be described as a real „controversy over human existence”.This paper will briefly outline some of the characteristics of the social changes that have occurred over the past fifty years and which have had a significant impact on the understanding of the nature of sexuality. Then, two apparently competing visions of man, the traditional and the modernist will be compared. As far as the traditional concept is concerned, reference will be made to the teachings of John Paul II. The modernist approach will be illustrated based on the „Standards for Sexuality Education in Europa” formulated by the World Health Organisation. The objective is not to settle the dispute, but to try and highlight its substance as well as the consequences arising from adopting one or the other of the proposed approaches.

ABSTRACT Background: Parkinson's disease (PD) produces autonomic changes, indicating lower parasympathetic modulation and global variability, but these changes need further studying regarding geometric methods. Objective: To investigate the autonomic modulation in individuals with PD using heart rate variability (HRV) indices obtained through geometric methods. Methods: This is a cross-sectional study that assessed 50 individuals, split into two groups: PD group (PDG; n=26; 75.36±5.21 years) and control group (CG; n=24; 75.36±5.21 years). We evaluated the autonomic modulation by measuring the heart rate beat-to-beat for 30 min with the individual in supine rest using a heart rate monitor and assessed geometric indices (RRtri, TINN, SD1, SD2, SD1/SD2 ratio, and qualitative analysis of the Poincaré plot). Results: Significant reductions were found in RRtri, TINN, SD1, and SD2 indices among PDG compared to CG. Regarding the SD1/SD2 ratio, no significant changes were detected between the groups. The Poincaré plot demonstrated that individuals with PD had lower beat-to-beat dispersion in RR intervals, in addition to greater long-term dispersion of RR intervals compared to CG. Conclusions: The results suggest a reduction in the parasympathetic autonomic modulation and global variability in individuals with PD compared to controls, regardless of sex, age, and body mass index.

Published: March 2021

ABSTRACT Background: Syphilis is an endemic disease, particularly in low- and middle-income countries, with vascular involvement in large vessels (aortitis), but no clear relationship with stroke patients, except for those who presented with meningovascular neurosyphilis. Objective: To investigate the relationship between a positive history of syphilis determined by serological testing and ischemic stroke etiology, particularly small vessel disease (SVD). Methods: In total, 269 first-ever ischemic stroke patients admitted to the stroke unit were tested for syphilis. Patients with neurosyphilis were excluded. All patients were classified according to the ASCOD phenotyping as SVD — when SVD was the potential causal mechanism (S1) — or non-SVD — when SVD was uncertain (S2), unlike (S3), or not detected (S0). Results: Syphilis was positive in 32 (12%) patients. When comparing patients with positive and negative serology, the only significant difference was SVD as the causal mechanism (S1) in patients with positive results: 9 (28%) vs. 22 (9%), p<0.01. Conclusion: The current study showed that the frequency of positive syphilis serological test was higher in patients with first-ever ischemic stroke and SVD as the potential causal mechanism. This finding could be related to the endothelial dysfunction occurring in syphilis.

ABSTRACT Objective: to identify sociodemographic and health characteristics according to age groups and to analyze the association between self-assessed health status and satisfaction with regular/bad life with sociodemographic characteristics, global functioning and falls of older adults linked to home care within the primary health care network. Method: cross-sectional study with 124 older adults, conducted using home interviews. A sociodemographic data and health status questionnaire was used, together with Barthel Index, Lawton Instrumental Activities of Daily Living Scale (IADL), the Mini-Mental State Examination, the Geriatric Depression Scale and the Timed Up and Go Test. Bivariate and multivariate analyses (Poisson regression) were applied. Results: there was a predominance of female octogenarians. Self-assessment of regular/bad health was associated with mild (p=0.002) and severe (p<0.001) depressive symptoms. Satisfaction with regular/bad life was associated with fear of falling (p=0.019) and with mild (p<0.001) and severe (p<0.001) depressive symptoms. Conclusion: depressive symptoms were associated with a worse life satisfaction and health self-assessment.

Abstract This work aimed to obtain aspartic proteases of industrial and biotechnological interest from the stomach of the crevalle jack fish (Caranx hippos). In order to do so, a crude extract (CE) of the stomach was obtained and subjected to a partial purification by salting-out, which resulted in the enzyme extract (EE) obtainment. EE proteases were characterized physicochemically and by means of zymogram. In addition, the effect of chemical agents on their activity was also assessed. By means of salting-out it was possible to obtain a purification of 1.6 times with a yield of 49.4%. Two acid proteases present in the EE were observed in zymogram. The optimum temperature and thermal stability for EE acidic proteases were 55 ºC and 45 °C, respectively. The optimum pH and pH stability found for these enzymes were pH 1.5 and 7.0, respectively. Total inhibition of EE acid proteolytic activity was observed in the presence of pepstatin A. dithiothreitol (DTT) and Ca2+ did not promote a significant effect on enzyme activity. In the presence of heavy metals, such as Al3+, Cd2+ and Hg2+, EE acidic proteases showed more than 70% of their enzymatic activity. The results show that it is possible to obtain, from the stomach of C. hippos, aspartic proteases with high proteolytic activity and characteristics that demonstrate potential for industrial and biotechnological applications.

Quem inventou a fome são os que comem: da invisibilidade à enunciação – uma discussão necessária em tempos de pandemia
Authors: Frutuoso Maria Fernanda Petroli , Viana Cássio Vinícius Afonso
Published: March 2021

Este texto tem o objetivo de discutir a importância da enunciação da fome com base na emergência da pandemia de Covid-19. Para tanto, apresenta um breve histórico sobre o uso dos termos fome e (in)segurança alimentar e nutricional, partindo da pioneira experiência brasileira de Josué de Castro e do pressuposto que nomear ou não a ausência regular de comida em quantidade suficiente para manutenção da vida como fome é um ato ético-político, com implicações diretas na construção de programas e políticas públicas para garantia do Direito Humano à Alimentação Adequada (DHAA) e Segurança Alimentar e Nutricional (SAN). Discute a concomitância da fome estrutural e conjuntural, que aponta para a nomeação da fome, não somente como conceito, mas como experiência, um dos caminhos de resistência para os conceitos técnicos, as teorias conformistas ou as produções colonialistas daqueles que comem.

Published: March 2021

Estudo qualitativo com abordagem cartográfica que teve como objetivo compreender os efeitos que o vínculo e a responsabilização entre médicos de família e usuários produzem nos próprios médicos. Foram realizadas dez entrevistas abertas por meio de perguntas disparadoras com médicos de família e médicos residentes. A análise das entrevistas se deu sob o referencial da micropolítica e problematizou, com base nas experiências relatadas, a existência de um “território identitário médico”, bem como as possibilidades de desconstituição desse território, sua desterritorialização no sentido de novas reterritorializações, a exemplo de afastar-se da onipotência/infalibilidade não para sofrer, mas para cuidar de si e do outro. Propõe-se que, nesse movimento de reconstrução do território identitário, tanto médico como usuário passem a transitar pela dimensão cuidadora do encontro, em que tecnologias leves podem ser operadas e novas possibilidades de configurações do cuidado acontecem.

Resumo O Programa de Auxílio Para Estudantes (Pape), da Universidade Federal de São Paulo, destina-se à assistência de estudantes com renda familiar per capita de até a 1,5 salário mínimo para garantir sua permanência na universidade. Os recursos vêm do Programa Nacional de Assistência Estudantil (Pnaes). O artigo analisa a eficácia do Pape e os possíveis impactos sobre o desempenho acadêmico. Para tanto, são comparados a evasão e os coeficientes de rendimento entre os participantes do Pape e os não participantes com perfil de renda igual. Os resultados mostram que, entre os participantes do Pape, o percentual de evadidos é menor e que o coeficiente de rendimento é maior e menos disperso. Conclui-se que o programa tem sido eficaz para garantir a permanência de estudantes vulneráveis e para promover condições de melhor desempenho acadêmico, porém, para preservá-lo, seria preciso ampliar seus recursos e transformar o Pnaes em política de Estado.

Resumo Este estudo analisa as trajetórias de insucesso e identifica motivos, estratégias e expectativas percebidas por 38 estudantes – 19 portugueses e 19 brasileiros – que elaboraram uma narrativa de autoformação e comentaram duas escalas para avaliar estratégias de autorregulação, de acordo com sua eficácia e utilização. Os estudantes mostram padrões de resposta semelhantes e refletem crenças e estratégias pouco adaptativas face à aprendizagem. Desmotivação, ansiedade, falta de persistência e características dos contextos universitário e familiar são percebidas como os principais motivos de insucesso. Os estudantes referem que a estratégia mais utilizada é a regulação pelas metas de resultado-evitamento e a mais eficaz, a gestão da atenção; revelam visão positiva do valor do curso para seu futuro, mas identificam uma grande discrepância entre os conteúdos lecionados e as exigências do mundo do trabalho.
A produção intelectual sobre Qualis Periódicos na área de Educação: um diálogo com as pesquisas acadêmicas (2008-2018)
Authors: Carvalho Eliane Souza de , Real Giselle Cristina Martins
Published: March 2021

Resumo Este texto tem como objetivo apresentar a sistematização acerca do que o campo acadêmico da área de Educação retrata sobre a avaliação da produção intelectual concretizada no Qualis Periódicos. Justifica-se a escolha da temática em virtude de sua centralidade na política da Pós-Graduação brasileira, presente nos atuais sistemas de verificação. Trata-se de uma pesquisa do tipo estado do conhecimento, em que foram escolhidas como unidades de análise a Biblioteca Digital Brasileira de Teses e Dissertações (BDTD) e o Banco de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes). A seleção resultou em 13 trabalhos, sendo 5 teses e 8 dissertações. Os dados indicam que o Programa Qualis não é um consenso entre pesquisadores, pois apresenta controvérsias: há aqueles que apontam que ele induz a um produtivismo que compromete a qualidade dos estudos; outros afirmam que ele contribui para a qualidade dos veículos de publicação e das investigações. Diante desse cenário, observa-se que a Capes promove alterações nos instrumentos de avaliação, buscando, a partir de uma lógica incremental e instrumental, qualificar e induzir a produção, inclusive internacionalizada.

Hippoboscid flies (Diptera: Hippoboscidae) on birds of prey in the Atlantic Forest, Minas Gerais, Brazil
Authors: Barino Glauber Thiago Martins , Dias Roberto Júnio Pedroso , Graciolli Gustavo
Published: March 2021

Abstract Hippoboscid flies are potential ectoparasites of several avian orders, including birds of prey, a group formed by the orders Falconiformes, Strigiformes, Cathartiformes and Accipitriformes. In this study, we evaluated 155 birds of prey that were brought to the Wildlife Rehabilitation Center of Juiz de Fora, Minas Gerais, Brazil, between the years 2016 and 2019. Two species of hippoboscid flies (Ornithoctona erythrocephala and Icosta americana) were found in five species of birds of prey (Megascops choliba, Asio stygius, Athene cunicularia, Asio clamator and Caracara plancus). The average intensity found was 1.4 hippoboscids/bird and Megascops choliba (tropical screech-owl) was the most parasitized bird. This is the first record of parasitism of Asio stygius (stygian owl) by Ornithoctona erythrocephala in Brazil and of Athene cunicularia (burrowing owl) and Asio clamator (striped owl) by Icosta americana. Ornithoctona erythrocephala is recorded here for the first time infesting birds of prey in the state of Minas Gerais, Brazil.

Published: March 2021

Introduction. Based upon two large randomized international clinical trials (German Dermatologic Cooperative Oncology Group (DeCOG-SLT) and Multicenter Selective Lymphadenectomy Trial II (MSLT-II)) which were published in 2016 and 2017, respectively, active surveillance has been demonstrated to have equivalent survival outcomes to completion lymphadenectomy (CLND) for a subset of patients who have microscopic lymph node disease. In this study, we examined the changes in national practice patterns regarding the utilization of CLND after positive sentinel lymph node biopsy (SLNB).

Methods. Using the National Cancer Database, we examined CLND utilization in SLN-positive patients diagnosed with melanoma between 2012 and 2016. A hierarchal logistical regression model with hospital-level random intercepts was constructed to examine the factors associated with SLNB followed by observation vs. SLNB with CLND.

Results. Of the 148,982 patients identified, 43% (n = 63,358) underwent SLNB, and 10.3% (n = 6,551) had a SLNB with microscopic disease. CLND was performed for 57% (n = 2,817) of these patients. Patients were more likely to undergo CLND if they were < 55 years of age (OR, 0.687;  p = <0.0001), ages 56 - 65 (OR, 0.886; p = 0.0237), Charlson Deyo Score = 0 (OR, 0.859; p = 0.0437), or were diagnosed with melanoma in 2012 (OR, 0.794, p = <0.0001).

Conclusions. We found the utilization of CLND among patients with microscopic nodal melanoma to be significantly lower in 2016 compared to 2012. Younger age, lack of comorbidities, and primary tumor location on the trunk or head/neck were associated with higher utilization of CLND.

We mostly use this method to transfect HEK293T cells for lentivirus production.
AN EFFECTIVE MACHINE LEARNING MODEL FOR CUSTOMER ATTRITION PREDICTIONIN MOTOR INSURANCE USING GWO-KELM ALGORITHM
Authors: Raju Ramakrishna Gondkar Deepthi Das,
Published: March 2021

The prediction of customers' churn is a challenging task in different industrial sectors, in which the motor insurance industry is one of the well-known industries. Due to the incessant upgradation done in the insurance policies, the retention process of customers plays a significant role for the concern. The main objective of this study is to predict the behaviors of the customers and to classify the churners and non-churners at an earlier stage.  The Motor Insurance sector dataset consists of 20,000 records with 37 attributes collected from the machine learning industry. The missing values of the records are analyzed and explored via Expectation Maximization algorithm that categorizes the collected data based on the policy renewals. Then, the behavior of the customers are also investigated, so as to ease the construction process training classifiers. With the help of Naive bayes algorithm, the behaviors of the customers on the upgraded policies are examined. Depending on the dependency rate of each variable, a hybrid GWO-KELM algorithm is introduced to classify the churners and non-churners by exploring the optimal feature analysis. Experimental results have proved the efficiency of the hybrid algorithm in terms of 95% prediction accuracy; 97% precision; 91% recall & 94% F-score.

Authors: Tugut Tursoy, Shanaz hakim ,
Published: March 2021

The analysis of this research focuses on the interactive relationship among the fluctuation of crude oil prices, the real GDP and the stock market of United State. This empirical investigation uses data is in between 1990 and 2018 with the Vector Auto-regression (VAR) analysis, and multiple regressions with its assumption were used in order to analyses data. 

Findings, oil price and economic growth are very important determinates of stock market in US because the p-value of this were less than the common alpha α =0.05. For instance, the crude oil price had positive impact on stock market because for each unit increasing of crude oil price, the stock market will increase by (0.276901) after holding all other variable constant. However, we find that GDP has negative impact on the participations of increasing the stock market.

Authors: Et al. Yuni Pratikno
Published: March 2021

Organisational culture is a system of shared beliefs and values in the organisation and directs its members' behaviour. There are various factors of change that influence organisational culture; various things are done to anticipate changes in the shift from the present situation to the desired conditions in a sustainable change. On the one hand, change occurs because of external factors that encourage change; on the other hand, change is an internal need. Change can be interpreted as absolute and unavoidable because of the strong external impulse and internal needs.

This research carried out at PT Briscor Horizon in 2020. This research was qualitative, namely research that intends to understand the phenomenon of what is experienced by the research subject holistic, and by way of description in the form of words and language, in a particular natural context and by utilising various natural methods.

The reduction of Crosstalk in VLSI due to parallel bus structure using Data Compression Bus Encoding technique implemented on Artix 7 FPGA Architecture
Authors: E Vijaya Babu, R. Prabhakar Syamala Yarlagadda, Srilakshmi Kaza,  Anil chowdary  Tummala,
Published: March 2021

In this work, a bus encoding method is proposed that reduces the effect of crosstalk. The crosstalk usually occurs when the data is in parallel communicated. In planar structures, the crosstalk effect is large due to the usage of parallel communication and wide data patterns. In bus technique, the huge amount of wires is laid in equal over a significant time. One way to reduce crosstalk without changing the parallel communicating data lines is to reduce the wideband data patterns so as to reduce the power utilization. The proposed encoding method can minimize the crosstalk by reducing wide data patterns without degrading the performance. The architecture is implemented on Artix 7 FPGA at a 28nm technology node. The simulation is done using the HDL tool and the results are compared with the existing FPGA architecture. With the proposed method, the wire density and the power consumption are reduced by 57.4% and 50% respectively as compared with existing 45 nm technologies.

IMPROVED SYSTEM FOR RETRIEVAL OF COLOR LOGO IMAGES USING PSO, SOM AND RELEVANCE FEEDBACK TECHNIQUE
Authors: Smita Selot Latika Pinjarkar, Manisha Sharma,
Published: March 2021

The colour logo identification has one of the key problems of bridging the difference between low-level characteristics and high-level semantics, as the consumer wants to. Relevance feedback (RF) along with self-organizing map (SOM) have been successfully introduced to resolve this void. However, the efficiency of the automated map (SOM) based RF is always low when the feedback sample is limited. This paper proposed a new technology, namely the SOM-SOM-RF that combines SOM-based RF with warm particle optimization, to boost RF performance (PSO). The aim of this proposed technology is to increase SOM-based RF efficiency and also to minimise user encounters with the device by reducing its RF number. On 3000 colour logo pictures, the PSO-SOM-RF was tested. The findings from the tests revealed the high precision of the proposed PSO-SOM-RF.
EXAMINING THE RELATIONSHIP BETWEEN THE FOREIGN LANGUAGE ANXIETY AND STUDENTS’ LEARNING MOTIVATION TO FILIPINO FOREIGN LANGUAGE LEARNERS
Authors: Quintos Sherrilyn B.
Published: March 2021

This quantitative research study investigated the relationship between anxiety acquired through foreign language learning and learning motivation of Filipino students in Bataan Peninsula State University. Participants were identified through stratified random sampling. It adapted two sets of questionnaires: Foreign Language Classroom Anxiety Scale by Horwitz, et al. (1986) and Foreign Language Learning Motivation Questionnaire developed by Gonzales (2006). Results showed that anxiety and motivation have a significant relationship with each other. Higher level of learning motivations students set for themselves manifest higher chances for them to develop consciousness and anxiety over their academic performance. They see L2 learning essential in employment opportunities, effective communication, and exploring foreign culture. However, their sense of interest to the course is primarily driven by extrinsic motivations which are only influenced by external factors such as the need to take the subject to pass a requirement. In return, they grow anxious and fearful of the possible consequences of being unable to achieve learning expectations and self-goals. While it is true that age does not significantly affect the relationship of the two variables under examination, it was found that females are more likely to exemplify a receptive behavior in learning than males. It is of high suggestion to integrate different strategies in teaching foreign language to minimize anxiety tendencies and maximize students’ engagement in learning. Also, it is recommended to devise or adapt a more context-specific questionnaire that will deeply explore on the intrinsic and extrinsic motivations of students and the anxiety concomitant to it. Finally, further studies are highly encouraged to be conducted to further navigate the interplay of other contributing variables in their foreign language learning experiences.
