Informe de las autoridades de las provincias coloniales que formaban el actual territorio de Panamá sobre el poblamiento, rendido con base en real cédula de 24 de abril de 1801.
Authors: Orozco Sarabia Karen Victoria , Romero Yorleth Santiago
Published: September 2021

Pese a que durante tres siglos la historia de Panamá estuvo ligada a la de Colombia, el conocimiento que tenemos los colombianos de la primera es nulo. Más allá de las múltiples razones de corto y largo plazo que explican la separación de Panamá, los vínculos entre el Caribe neogranadino y el Istmo fueron intensos a lo largo del periodo colonial. Y continuaron durante el último tercio del siglo XIX cuando se desarrollaban los trabajos de construcción del canal interoceánico. Por eso sigue siendo un error seguir estudiando el Caribe neogranadino y el del siglo XIX sin incluir a las distintas provincias que formaban a lo que hoy es la actual república de Panamá.

Authors: Qian Chen , Nair Subadrah Madhawa
Published: September 2021

In this age of globalization, EFL writing skills are essential for Chinese undergraduates, especially in the areas of communication, education and business cooperation. The objective of this study is to study and analyze EFL descriptive writing errors among Chinese undergraduates, according to gender and faculty of study. Descriptive research design was employed in this study. The undergraduate students in the study were given a descriptive writing test and their essays were marked by a lecturer using rubric provided by the researchers. The sample of the study consisted of 400 Chinese undergraduate students (200 males and 200 females,) from Hunan City University in Hunan Province, China. Stratified random sampling was employed in selecting the samples. Students’ errors in EFL writing were analyzed based on Corder’s error analysis and James’s classification of errors. The findings from quantitative data revealed that male students made significantly more errors than female students in their overall writing, mechanical, coherence and cohesion, grammar, lexical and sentence structures. There is also significant difference in the mean errors among students from the four faculties. Moreover, the results indicated that the students from the faculties of Education Management and Chinese Language Studies (social sciences) performed better than the students from the other faculties. In terms of pedagogical implications, the findings suggest that further research should be carried out to minimize male students’ errors in their writing skills as well as the students from the Information Technology and Civil Engineering faculties.
Comparison of Technical and Fundamental Analysis Trading Disciplines on Portfoilo Performance: Short and Long Term Backtest Analysis on Borsa İstanbul National Stock Indices
Authors: ÖZYEŞİL Mustafa
Published: September 2021

The aim of this study is to comparatively analyze the backtest performances of trading disciplines applied in various portfolio baskets (Bist 30, 50 and 100) for different investment periods (short term – ytd and long term). According to the results of the analysis, it has been determined that in all trading disciplines, the investor has a higher return than the benchmark indicator in a 5-year term, that is, they can earn abnormal returns. Also, the return in the 5-year term is much higher than the 1-year and YTD returns. In the P / E & MA model, the Bist - 50 index in the 5-year period and the Bist - 100 index in the 1-year period provide the maximum return, while according to the P / E model, the Bist-30 and Bist -50 indices provide optimum returns in all maturity options. Based on these findings, it can be expected that if the trading disciplines used in this study are applied in a long term such as 5 years and on the portfolio basket consisting of Bist-30 and Bist-50 industrial stocks, it will maximize returns. In terms of risk and return, in YTD period, the sharpe and treynor ratios of the model portfolio formed in all trading disciplines except M /B trading discipline were lower than in 1 year in the 5-year investment period. This situation arose due to the increased risk of the portfolio as a result of the extended maturity and is in line with our expectations.

Authors: Hadjadji Narimane , Hamdi Rachid
Published: September 2021

In this paper, we demonstrate the efficiency of Electronic Dispersion Compensation (EDC) for coherent optical systems based on Polarization Division Multiplexed Quadrature Phase Shift Keying (PDM-QPSK). The performance of the proposed system is tested using a pulse that has been recently used in the presence of nonlinear effects.The proposed system is compared to the 0.3RZ-PDM-QPSK system at the optimum launched power under different symbol-rates and lengths of transmission. The simulation results confirm that the proposed method enhances the system performance. In addition, it secures a low penalty that is below 0.6 dB. As a result, the feasible transmission distance is improved by 29 %, 20.15 %, and 26.7 %, at 14 GBaud, 28 Gbaud, and 56 Gbaud, respectively.

Authors: Cigdemoglu Ceyhan , Geban Omer
Published: September 2021

This study explores whether the context-based approach with 5E model (CBA-5E) can lead to better understanding of chemical reactions and energy concepts when compared to conventional instruction (CI). Additionally, the study delves into the effect of treatment with regards to gender. Eleventh grade science-major classes with 175 students from two public high schools were enrolled. The experimental groups were treated with CBA-5E, the control groups as CI, the treatments were randomly assigned to the groups. The chemical reactions and energy concepts test, including the common alternative conceptions, was administered as pre- and post-test. The chemical reactions and energy achievement test, including conceptual and algorithmic problems, was administered as a post-test to the groups. Multivariate Analysis of Covariance (MANCOVA) was used for the analysis of the data, and the results revealed that CBA-5E was superior to CI on the students’ conceptual understanding regarding these concepts regardless of gender difference.

EXPLORING THE RELATIONSHIP BETWEEN COGNITIVE STRUCTURE OUTCOMES AND TEST ACHIEVEMENTS OF PRE-SERVICE SCIENCE TEACHERS ON CHEMICAL BONDING VIA FLOW MAPPING
Authors: Atabek-Yigit Elif
Published: September 2021

The relationship between cognitive structure outcomes of students and their test achievement was examined in this study. A question form and two types of tests (a multiple-choice test (MCT) and a true-false test (TFT)) were used to gather the research data. According to the results of this study, extend, richness and integratedness of students’ statements significantly correlated to their scores in TFT. Also, richness of students’ statements was significantly correlated to their MCT scores. Describing and comparing were significantly correlated with MCT scores, while describing, comparing and inferring were significantly correlated with the students’ TFT scores. Therefore, it can be said that tests reflect students’ cognitive structures. Furthermore, students with higher order thinking skills can be identified by TFT rather than with MCT. Students’ misconceptions about the research topic were also examined, and they were generally on the classification and types of chemical bonds.

The Place of Slavophilism in the Typology of Conservatism
Authors: Teslya Andrey
Published: September 2021

In the history of political thought, Russian Slavophilism of the period from 1840s till 1880s has two established traditions of interpretation: as a variant of conservative ideology and as one form of Russian liberalism of the 1840s, along with Westernism (in this case, the later history of Slavophilism, i.e. the period between 1860s and 1880s, is viewed as a departure from initially liberal stances. Beginning with the framework of Andrzej Walicki, the article attempts to demonstrate the underpinnings of this peculiar duality of evaluations. Slavophilism is understood as liberal conservatism; the article also uncovers the structural conditions, on which the liberal component of Slavophile views are based. Special attention is given to the analysis of processes, which led to the dominance of the interpretation, according to which Russian Slavophilism is a conservative ideology, where the liberal component is defined as situational. The reason for such a reading are rooted in the peculiar position of Russian liberalism in the late XIX century, when the nationalism agenda was interpreted as entirely pertaining to the conservative side of the political spectrum.

Authors: Rouf Hidayat Abdul , Wijayanto Ardhi , Aziz Abdul
Published: September 2021

Abstract— The rise of plagiarism is one of the negative impacts of the development of information and communication technology. Plagiarism can occur anywhere. One of the examples is a university with the object of plagiarism as a student's final project. So we need a system to detect plagiarism so that it can suppress plagiarism in the college environment. In detecting the similarity of a writing will be faster if the writing has been grouped before compared to each other. Single-link clustering was chosen because it has a simple algorithm and can be implemented without the initial cluster. In plagiarism plagiarism usually changes the sentence structure so that it looks different Jaro-Winkler distance is chosen because it can detect similarities in paragraphs that have been changed in sentence structure because Jaro-Winkler distance has a flexible indexing with theoretical distance so that a word or character is considered the same. The stages in this study include data collection, preprocessing, grouping writing with Single-link clustering, comparing writing with jaro-winkler distance, and testing with precision and recall. After testing, the average value of precision was 84.37% and recall was 84.37% with a level of plagiarism of 99.1%. Keywords—: jaro-winkler distance; plagiarisme; single-link clustering.

Psicanálise e prática multidisciplinar: (im)possíveis desdobramentos do trabalho com crianças autistas e pais
Authors: Nicolau Roseane Freitas , Barros Izabella Paiva Monteiro de
Published: September 2021

Dificuldades costumam estar associadas a sofrimento, mas podem também ser mote para reflexão e cuidado.  Nesse artigo trabalhamos alguns desdobramentos da pesquisa desenvolvida ao longo de seis anos em um hospital universitário do norte do país, mais especificamente aqueles que surgiram a partir das intervenções clínicas no serviço que acolhe crianças com autismo, síndromes neurológicas graves, problemas de aprendizagem, hiperatividade, dentre outros diagnósticos. Como analistas no hospital, orientadas pelo método clínico, partimos dos pressupostos freudo-lacanianos que sustentam a suspensão diagnóstica, até que se tenha apreendido, para além das causas orgânicas, as tramas simbólicas imbricadas com o sintoma da criança. Como instrumento de trabalho utilizamos a escuta dos pais e da criança, a transferência e a relação terapêutica como eixos centrais para o tratamento, pois acreditamos que o diagnóstico apressado pode precipitar prescrições medicamentosas cujos efeitos seriam prejudiciais para o desenvolvimento infantil. Problematizamos as dificuldades no trabalho clínico nas instituições as quais, muitas vezes, funcionam na contramão da aposta na saúde psíquica com suas particularidades. Foi possível constatar que há possibilidade de sensibilizar a equipe para a importância de acolher o que é da ordem da experiência, dando alguma possibilidade de amarração para o sujeito do inconsciente. Para tanto, devemos efetivamente sustentar junto à equipe, a possibilidade de emergência do sujeito, este que é dividido e que porta um saber que ele desconhece. Aposta importante, não apenas para o tratamento da criança e seus pais, mas também para o trabalho multidisciplinar, no qual seguimos no exercício (im)possível da intertextualidade.

Molecular electrostatic potential (MEP) and pattern recognition (PR) were used to draw potentially active pentamidine derivatives against Trypanosome brucei rhodesiense (T. b. rhodesiense). PR models: Principal Component Analysis, PCA model; Hierarchical Cluster Analysis, HCA model; K-Nearest Neighbor, KNN model; Soft Independent Modeling of Class Analogy, SIMCA model; and Stepwise Discriminant Analysis, SDA model, were built by reducing the dimensionality of a data matrix to twenty-eight pentamidine derivatives and allowed the compounds to be classified into two classes: more active and less active, according to their degrees of activity against T. b. rhodesiense. The study outlined that the properties HOMO (highest occupied molecular orbital) energy, VOL (molecular volume), and ASA_P (water accessible surface area of all polar (½qi½³0. 2) atoms) are the most relevant for the construction of the models. The key structural features required for biological activity investigated through MEP were used as guidelines in the design of thirteen new compounds, which were evaluated by PR models as more active or less active against T. b. rhodesiense. The application of PR models indicated nine promising compounds (29, 30, 31, 32, 33, 36, 37, 39, and 40) for synthesis and biological assays.
Infiltração neoplásica em coluna vertebral decorrente de adenocarcinoma mamário: relato de caso
Authors: Silva Pablo José Custódio Bezerra da , Costa Ruth  Silva Lima da
Published: September 2021

As metástases na coluna vertebral têm por caráter etiológico a disseminação hematogênica, linfática, liquórica ou invasão direta por contiguidade. O carcinoma de mama é o que apresenta maior predileção pelo tecido ósseo, apresentando lesão osteolítica em aproximadamente 80% dos pacientes. O objetivo do estudo foi descrever o relato de caso de uma paciente acometida por uma infiltração neoplásica em coluna vertebral decorrente de adenocarcinoma mamário, com sítio primário ainda desconhecido.  Trata-se de um estudo observacional do tipo descritivo, realizado através dos dados clínicos de uma paciente acometida por carcinoma mamário, diagnosticada inicialmente com fibromialgia, sendo transferida para internação e elucidação diagnóstica. Evoluiu com paraplegia súbita, lesões osteolíticas generalizadas, de caráter metastático. Observou-se que mesmo após a realização da anamnese, exame físico, avaliações multidisciplinares e exames de imagem, estes foram incapazes de identificar o foco neoplásico do caso em questão e que somente após a realização do exame de imuno-histoquímica é que foi possível a identificação do foco primário em mama. Sendo assim, é essencial a busca por métodos investigativos, mais especificos, que auxiliem na elucidação do diagnóstico, permitindo assim o estabelecimento da terapéutica adequada e consequentemente um melhor prognóstico para os acometidos.

Methods: First were made a screening with broth microdilution test, protocol M7-A9, according to CLSI. Extracts that presented values for Minimal Microbicidal Concentration (MMC) were selected for biofilms tests on 96 wells plates. Treatments used concentrations of 25 and 50 mg/mL, after biofilms were measured by biomass and MTT tests and statistically analyzed by ANOVA and Tukey test (p<0.05). Results: All extracts showed MIC for all K. pneumoniae strains studied, with values ranging from 12.5-100 mg/mL. Biomass of the strains ATCC and MDR strain (400381) of K. pneumoniae obtained reductions of 37.7 and 44.3% with P. paniculata and R. officinalis extracts. The isolate 386546 obtained a reduction of 29.7% (p<0.05) under R. officinalis action. Conclusion: Among the extracts studied, those that were most effective in the anti-biofilm action were J. regia, P. paniculata and R. officinalis. Therefore, these extracts could act as bactericidal agents against K. pneumoniae MDR.

Diante de uma escola inserida no campo é elementar a compreensão da percepção ambiental dos estudantes em relação ao meio ambiente. Objetivou-se neste trabalho identificar a percepção sobre o meio ambiente de alunos dos anos finais do ensino fundamental do município de Paulista-PB. A pesquisa teve como objeto de estudo os estudantes de duas escolas da zona rural do município de Paulista-PB no período de março a junho de 2021, com a participação de 136 alunos. A pesquisa foi descritiva qualitativa e obteve os dados através de formulário relacionando a temática do meio ambiente. Diante da análise deste estudo registrou-se que 89% dos alunos de ambas escolas são conhecedoras da definição do termo sobre o meio ambiente, mas, sentem dificuldades em se entenderem como integrante do meio ambiente. Foi identificado uma carência dos alunos em perceberem temas ambientais de forma interdisciplinar, porém, ficou evidenciado uma positiva participação da escola no processo de ações e projetos com a temática ambiental, contribuindo para o desenvolvimento crítico dos alunos perante aos problemas ambientais.

This paper aims to clarify and present discussions about the COVID-19 disease, its variants and prevention measures, as well as clarifying the excessive use of antimicrobials in the protocols of patients infected with it, as this practice can intensify an already existing public health problem, which is antimicrobial resistance. The methodology used in this research was a literature review on bacterial resistance due to the indiscriminate use of antimicrobials and the possible impacts caused in the COVID-19 pandemic, as well as the variants of worldwide concern, based on the Scientific Electronic Library Online databases - SCIELO, National Library of Medicine - PubMed, CAPES Journal Portal, Academic Google and National Health Surveillance Agency (ANVISA). Based on the literature presented here, it is concluded that COVID-19 is a disease caused by the acute respiratory syndrome (SARS-CoV-2) presenting a clinical spectrum ranging from asymptomatic infections to severe conditions. Several variants have emerged in several countries modifying the dynamics of transmissibility and potential immune flight from the disease, the Delta variant (B.1.617.2) being a greater threat to public health due to its high transmissibility. The misuse and excessive use of antimicrobials prescribed for the treatment of this disease can favor the emergence of superbugs and such resistance is a global problem. Therefore, the help of laboratory and clinical tests is essential to carry out a therapeutic intervention, observing the best options for each clinical case, since COVID-19 is a new disease and still under study.

Devido à capacidade de germinar, crescer e reproduzir-se em condições contrárias, como em situações de déficit hídrico, salinidade, solos ácidos ou alcalinos e temperaturas pouco propícias, as plantas daninhas tem sido um dos problemas fitossanitários mais difíceis de serem controladas nas áreas agrícolas, podendo resultar em prejuízos que podem chegar a altos níveis de perdas da lavoura. Objetivou-se com esse estudo avaliar a eficiência da aplicação isolada de Glyphosate, e associado aos herbicidas Chlorimuron, Imazethapyr, Lactofen e Flumioxazin no controle da Ipomoea grandifoli. Para isso, foi conduzido um experimento na casa de vegetação do campo experimental do UNIVAG – Centro Universitário de Várzea Grande. O delineamento experimental adotado foi o de blocos casualizados, com seis tratamento (Glifosato, Glifosato + Imazethapyr, Glifosato + Clorimoron, Glifosato + Flumioxazin, Glifosato + Lactofen eestemunha) e quatro repetições totalizando 24parcelas. Para determinação dos resultados, foram realizadas avaliações de fitointoxicação com base em uma escala visual de notas aos 7, 14 e 21 dias após a aplicação. Entre os herbicidas testados, os tratamentos com Glifosato + Flumioxazin e Glifosato + Lactofen produzirem o melhor resultado (100% de controle), já os tratamentos utilizando Glifosato isolado, Glifosato + Imezethapyr e Glifosato + Clorimuron demonstraram controle inferior para controlar a corda-de-viola.

Electrical Resistivity method using
Vertical Electrical Soundings (VES) were carried
out at a site in Aba-Oyo area FUTA Southgate area,
Akure, Nigeria, with the aim to access groundwater
potential of the site. The study area is underlain by
crystalline rocks of the Precambrian basement
complex of the Southwestern Nigeria. Twelve (12)
VES were carried out using Schlumberger
electrode array configuration with AB/2from 1 to
65m. The VES data generated were processed and
interpreted using partial curve matching method
and computer iteration techniques. The interpreted
data revealed three to four geoelectric sections with
varied thicknesses and resistivity. The top soil layer
ranges from 44 to 181?m, lateritic clay layer
ranges from 20 to 174?m, the weathered horizon
resistivity ranges from 20.0 to 424.0?m while the
competent rock/fresh rock has resistivity values
greater than 424.0.3?m. The top soil layer
resistivity and thickness ranges from 44 to 181?m
and 0.4 to 2m, the lateritic clay layer resistivity and
thickness range from 20 to 174?m and 1.7 to 6.0m
respectively, the weathered horizon resistivity
ranges from 20.0 to 424.0?m and 1.4 to 7.4m
respectively while the competent rock has
resistivity values greater than 424.0?m and ?m
respectively. The third geoelectric layer constitutes
the aquiferous zone in the 4-layer geoelectric
section while the second geoelectric layer is the
aquiferous zone in all the 3- layer geoelectric
sections. VES station 2, 7, 9 stations shows good
groundwater potential as revealed by the thick
overburden and weathered layer with low
resistivity values. VES stations 1, 4, 5, 6, 8, 10 and
12 shows moderate groundwater potentials while
VES stations 3 and 11 are non-aquifereous in
nature.

Noise Pollution is a growing problem in
Modern cities, thanks to rapid population growth,
urbanization and new technologies. Moreover, at times, a
noisy neighbor or co-worker can drive you crazy and
affect your wellbeing. Traffic light control systems ar
widely used to monitor and control the flow of
automobiles through the junction of many roads. They
aim to realize smooth motion of cars in the transportation
routes. However, this system also leads to Noise Pollution
which this present traffic signal doesn’t considers a
problem. But any sound which crosses the parameter of
90 Hz is considered Noise which you’ll get to hear at each
and every traffic signal present at every adjacent
intersection. Exposure to prolonged or excessive noise has
been shown to cause range of health problems ranging
from stress, poor concentration, productivity loss in the
workplace, and communication difficulties and fatigue
from lack of sleep, to more serious issues such as
cardiovascular disease, cognitive impairment, tinnitus
and hearing loss. Hence, to overcome all these problems
and help our society we propose a system based on
Arduino with High-end microphone sensors and our
algorithm to detect and distinguish between Normal
sound and Noise based on that decision Vehicle riders
present at that traffic signal will be penalized with extra
time to spend on that junction
FLOOD AVOIDANCE USING IOT

Flood is a common problem not only in
India but worldwide and most of the water bodies are
easily accessible to common people. At times it may
happen that the weather conditions may change
suddenly and the water bodies may become violent,
resulting in a flood which can lead to loss of lives as
well as livestock. Therefore, a rapid flood detection
system that can reach a wide area such as the internet
is necessary to minimize the effects of disasters. So, this
paper proposes a flood detection system with the help
of the Internet of Things (IoT). IoT is a smart
technology that has the capability to send data in realtime. The system is powered using Arduino and has 3
sensors to detect 5 different parameters. Firstly, to
measure temperature and humidity we have DHT-11
Digital Temperature and Humidity Sensor. Then we
have the Water Flow sensor to check the flow of water.
And lastly, to measure the distance and water level we
have HC-SR04-Ultrasonic Range Finder and Distance
Sensor. Finally, the collected information is
transmitted to LCD to display the information. The
system continuously keeps checking any changes in the
weather condition and updates the live data over IoT.
In case the parameters reach a dangerous level the
system immediately alerts the people.
MODIFIED QUADRATIC BUCK BOOST CONVERTER FOR PV APPLICATIONS
Authors: Mohan S Aparna , K R Prof. Anjana
Published: September 2021

Buck-boost DC/DC converters have been
extensively employed in stepping up/down the voltage for
PV applications. The input and the output port current of
the traditional quadratic buck-boost converter are
discontinuous, which result in increased input and output
current ripples and complicate the design of the input and
output filters. Hence these problems can be solved by using
a modified quadratic buck boost converter, which provides
wider voltage conversion ratio with continuous input and
output ports current. Dual output can be derived from this
single input converter for multiple output applications. Also
a fuzzy logic controller can be designed for this proposed
converter for better and faster performance.
IMAGE ENCRYPTION FOR SECURE INTERNET TRANSFER

Published: September 2021

Security is a crucial side to preserve the
confidentiality of information such as pictures and text.
The probability of an assailant attempting to access the
image in the course of transferring process is high as
assailant may get hold of important data. Therefore,
encryption methods are used for securing the data. A
novel image encryption algorithm that is a combination of
the AES algorithm and the chaos sequence is proposed in
this paper. The project will use AES for encryption and
decryption of the image transfer because AES is capable
of solving problem that cannot be resolved by different
algorithms. The original image is transformed into
cipher-image using a share secret key and this process is
called encryption while the reverse of encryption process
is known as decryption. This method’s sensitivity to the
initial values and input image, even the tiniest changes
within these values will result in significant changes in the
encrypted image. We show that this approach can shield
the image against different attacks exploitation using
histogram analysis.
