Authors:   , Laguardia Giovana Caetano de Araujo
Published: November 2022

Em março de 2020, a Organização Mundial da Saúde declarou o coronavírus 2019 ou covid-19 como doença pandêmica e de emergência em saúde pública. O conhecimento em construção sobre a patogenicidade e transmissibilidade do vírus Sars-CoV-2 tem exigido respostas rápidas dos sistemas de saúde, com base nesse cenário. Nesse sentido, foi realizada uma revisão de escopo com o objetivo de mapear as estratégias técnicas e gerenciais para manejo e redução da produção de partículas aéreas nos procedimentos cirúrgicos durante a pandemia da covid-19. Foi adotada a metodologia Joanna Briggs Institute (JBI) para revisão de escopo, com documentos indexados nas bases de dados Medline, BVS, Cinahl, Biblioteca Cochrane, Embase, Scopus e Web of Science, publicados na íntegra em português, inglês ou espanhol, entre dezembro de 2019 e julho de 2021. Foram incluídos estudos provenientes de revistas acadêmicas indexadas e protocolos publicados por associações acadêmicas que envolvam recomendações em saúde sobre procedimentos técnicos e gerenciais para manejo e redução de produção de partículas aéreas de pacientes infectados pelo Sars-CoV-2. Foram excluídos estudos que não contivessem informações sobre manejo de partículas aéreas (gotícula ou aerossol) ou que não estivessem relacionados à assistência à saúde no centro cirúrgico. Resultados: dos estudos analisados na íntegra, foram selecionados 18 trabalhos, que tiveram seus resultados categorizados em: recomendações para o ambiente; recomendações para a equipe e recomendações para técnica/procedimento cirúrgico. Conclusão: as evidências sobre o manejo e a redução da produção de partículas aéreas nos procedimentos cirúrgicos se sustentam em recomendações relacionadas ao ambiente do centro cirúrgico, à equipe multiprofissional e ao procedimento cirúrgico. As implicações da pesquisa para a prática de enfermagem relacionam-se à produção de um mapa de recomendações para controle de produção de partículas nas atividades do centro cirúrgico e na proteção da equipe.
A história evolutiva de Trypanosoma: elucidando as relações filogenéticas do grupo por meio de distintos métodos e marcadores
Authors:   , Lima Mylena Barros de
Published: November 2022

O presente estudo possui como objetivo aplicar uma metodologia de análise de sequência-estrutura, para estimar a árvore evolutiva do gênero de parasitos flagelados Trypanosoma, e realizar a comparação entre métodos de inferência já utilizados pela literatura, como a análise concatenada entre a sub-região V7V8 do marcador molecular SSU 18S rDNA e o gene gGAPDH, além da análise somente com o gene SSU 18S rDNA. Através das análises comparativas, pôde-se perceber que os resultados estão de acordo com as informações prévias geradas pelas análises baseadas em dados com o gene 18S rDNA, corroborando teorias evolutivas e a ordem geral de ramificação das topologias. Assim, a análise de sequência-estrutura possibilitou acessar relações filogenéticas profundas entre as espécies de tripanossomas. A nova metodologia de sequência-estrutura conseguiu acessar todos os subgêneros conhecidos até então utilizando um único marcador molecular (SSU 18S rDNA) com máximo valor de suporte. Além disso, os resultados da análise de sequência-estrutura foram mais robustos do que as demais análises, mais sensíveis a artefatos deixados por táxons Rogue (id.est. incertae sedis) e a espécies ligadas ao efeito de atração de ramos. Saber qual foi a real história evolutiva destes parasitos é uma incógnita, mas a utilização de ferramentas que ofereçam maior poder de resolução para as relações filogenéticas pode ser uma saída. Desse modo, o presente estudo indica uma ferramenta altamente eficiente para análises filogenéticas de Trypanosoma. Ademais, a utilização de metodologias que permitem análises profundas do agrupamento, exigindo menos marcadores moleculares, são de extrema importância.

Investigação do desempenho aerodinâmico de um avião de pequeno porte utilizando dinâmica dos fluidos computacional
Authors:   , Vidigal Luís Pedro Vieira
Published: November 2022

O presente trabalho propôs investigar o desempenho aerodinâmico da aeronave Brasília (EMB120). A escolha desse modelo como estudo de caso se justifica dentro das atividades do GCEME de pesquisas em propulsão híbrida. Por meio da utilização do OpenFOAM, foram desenvolvidas simulações utilizando o modelo RANS juntamente com o modelo de turbulência k − ω SST. As simulações conduzidas se concentraram na fase de cruzeiro, onde a simplificação de escoamento em regime permanente é válida. Foi possível identificar que a aeronave em questão é capaz de realizar o voo de cruzeiro sob um ângulo de ataque na faixa de 1 o a 3 o , onde seu centro de pressão fica localizado na faixa entre 26, 92% e 28, 47% da corda média aerodinâmica. As asas são o principal componente responsável por gerar sustentação, enquanto as asas em conjunto com a fuselagem geram a maior parte do arrasto aerodinâmico. Duas configurações da aeronave foram avaliadas: uma com e outra sem twist geométrico nas asas. Um aumento no arrasto e na sustentação globais foram observados para a configuração com twist, embora a relação entre essas forças não tenha se alterado significativamente. Uma avaliação das equações utilizadas para inicializar os parâmetros de turbulência foi conduzida, onde não foi possível obter diferença significativa entre formulações diferentes. Investigou-se, ainda, a influência da altitude no desempenho aerodinâmico da aeronave. Não foram observadas mudanças significativas nos seus coeficientes adimensionais

Authors:   , Mesquita Júnior Gilmar Alves de
Published: November 2022

A espécie Coffea arabica L. corresponde a mais de 60% de todo o café produzido no mundo. O produto que de fato é comercializado internacionalmente são seus grãos verdes, enquanto suas folhas são consideradas um resíduo. O aproveitamento das folhas de café revela-se promissor uma vez que estão amplamente disponíveis e são fontes de diversas substâncias bioativas. Assim, o objetivo deste estudo foi avaliar a atividade antibacteriana in vitro do extrato etanólico liofilizado de folhas de café arábica (EE-CaL) e investigar os compostos presentes nesse extrato. O efeito antibacteriano in vitro de EE-CaL foi avaliado usando o método de microdiluição em caldo e o método de drop plate em ágar adaptado para determinar a Concentração Inibitória Mínima (CIM) e a Concentração Bactericida Mínima (CBM), respectivamente. Foram selecionadas cepas bacterianas de referência Grampositiva [Staphylococcus aureus subsp. aureus Rosenbach (ATCC 29213)] e Gramnegativa fermentadora [Escherichia coli (Migula) Castellani and Chalmers (ATCC 25922)] e não-fermentadora [Pseudomonas aeruginosa (Schroeter) Migula (ATCC 27853 e ATCC 9027)] com base na lista de bactérias patogênicas prioritárias para orientar a descoberta, pesquisa e desenvolvimento de novos medicamentos publicada pela Organização Mundial da Saúde (OMS). A caracterização química de EE-CaL foi realizada por meio de CLUE-EM-Q-ToF. EE-CaL foi ativo frente a S. aureus (ATCC 29213) e E. coli (ATCC 25922), sendo mais efetivo frente a esta última (CIM = 2500 μg/mL e efeito bactericida), e sendo inativo frente a P. aeruginosa (ATCC 27853 e ATCC 9027) nas concentrações testadas. A análise química de EE-CaL revelou a presença de compostos da classe dos alcaloides, como a trigonelina e a cafeína, além de compostos fenólicos como o ácido quínico, ácido 5-cafeioquínico, ácido cafeico-O-hexosídeo, mangiferina, (epi)catequina, (epi)catequina mono glicosídeo e trímero de procianidina. A maioria desses compostos apresentam atividade antimicrobiana descrita na literatura, incluindo frente a E. coli e S. aureus, sendo assim, eles podem estar relacionados com a atividade antibacteriana observada em EE-CaL no presente estudo.
Revisitando Lilith: um estudo sobre indecência e libertinagem em diálogo com a Teologia Queer de Marcella Althaus-Reid
Authors:   , Sarto Giovanna
Published: November 2022

Lilith: Mulher-demônio, primeira esposa de Adão, expulsa do paraíso por se recusar a ficar sob ele durante o ato sexual. Sentenciada a viver sozinha, vagando pelas trevas, atormentando crianças recém-nascidas. O mito de Lilith possui diversas nuances, que frequentemente convergem a um ponto – o da associação ao caos e ao libertino. Todo mito religioso é contextual e constitui-se enquanto uma linguagem da religião que conta e ensina sistemas e representações. Mas ele não é uma zona neutra. Ao contrário, o mito é uma poderosa ferramenta cujo sentido é atribuído a partir de crenças, valores, experiências e intenções de um grupo ou comunidade. Tradicionalmente, Lilith tem sido usada como um exemplo a não ser seguido. Especialmente para mulheres, ensina uma sexualidade e um comportamento que, mais do que evitado, deve ser temido. Mas por quê? Como chegou-se a essa intepretação? Quais os efeitos dela? E ainda, de que forma é possível reconstruir o mito de Lilith a partir de uma interpretação menos estática em termos de gênero e sexualidade? Partiu-se dessas perguntas para investigar as construções pedagógicas deste mito, sob a hipótese de que ele tem contado e ensinado determinadas pedagogias, especialmente pedagogias de gênero e sexualidade restritivas, que têm sido pouco investigadas nos estudos tradicionais, e que é possível contá-las de uma outra forma a partir de uma hermenêutica indecente, nos termos da Marcella AlthausReid. A dissertação utilizou-se de metodologia qualitativa, a saber, um levantamento documental parcial sobre mitologia mesopotâmica e lilithiana e um levantamento bibliográfico sobre a hermenêutica queer nos estudos em religião. A intenção é investigar como as pedagogias de gênero e sexualidade têm sido operadas no mito de Lilith e de que maneira podem ser subvertidas em uma proposta indecente.
O impacto da financeirização da moradia na revisão do atual Plano Diretor de Juiz de Fora- MG
Authors:   , Fernandes Raísa Coelho
Published: November 2022

A presente pesquisa buscou verificar se a financeirização da moradia, enquanto fenômeno mundial, afetou o processo de revisão do Plano Diretor Participativo de Juiz de Fora, especialmente nas disposições legais diretamente relacionadas à efetivação do direito à moradia. A literatura sobre a temática demonstra que a financeirização, enquanto principal característica da atual fase do capitalismo, modifica a formação do espaço urbano e transforma a habitação em importante ativo financeiro, afetando o direito à moradia e as políticas públicas habitacionais. Assim, considerando a amplitude global desse fenômeno econômico sobre o desenvolvimento urbano e a influência do capital financeiro sobre as cidades, nota-se que os efeitos da financeirização passaram a afetar também as cidades de porte médio, como Juiz de Fora. Nesse cenário, a partir das regras de inferência e implicações observáveis, com adoção da metodologia empírico-qualitativa documental, elegeu-se como objeto de pesquisa o processo legislativo de revisão do Plano Diretor Participativo de Juiz de Fora, iniciado em 2013 e finalizado em 2018. Os dados, coletados através dos sítios eletrônicos da Prefeitura Municipal de Juiz de Fora e da Câmara Municipal de Juiz de Fora, foram analisados tendo como marco teórico os preceitos da financeirização da moradia. Dessa forma, foi possível verificar que durante o processo houve baixa participação da população, apesar da opção por um processo legislativo calcado nos fundamentos de participação social. A baixa adesão da população é fator determinante para a expansão da financeirização, já que esse fenômeno modifica as relações políticas, afetando a atuação estatal. Além disso, notou-se que o Plano Diretor Participativo, através da criação de um elo público-privado, incentivou o investimento e, por consequência, a atração do mercado financeiro, para as áreas mais desenvolvidas da cidade, como a região central. Essa prevalência da região central, já dotada de boa infraestrutura, em relação às demais áreas da cidade, gera o afastamento da população de baixa renda para as periferias, aumentando a segregação socioespacial.
Mapping Mandeville ADN
Authors: Greenlee John Wyatt
Published: November 2022

The Mapping Mandeville Project is a web-based project that maps locations from the 14th-century travel narrative, The Travels of John Mandeville onto a modern reproduction of the 13th-century Hereford Map. Some locations such as cities are marked on the map. Others are unmarked, but highlight when the user scrolls over them with the cursor. Scrolling over any map element that is in book brings up the name of the location on the screen. Clicking on the element brings up all of the text related to that location. The text is drawn from a modern English edition of The Travels. Viewers can, thus, investigate the map to discover the geography of the book’s stories. This project is pedagogical in nature, with the goal of helping students better understand the geography of the book, while using the book’s text as an introduction to medieval maps.

Published: November 2022

Для выполнения реставрационных работ, отвечающих требованиям современной эстетической стоматологии, на кафедре терапевтической стоматологии БелМАПО разработаны практикумы, направленные на поэтапное, последовательное освоение врачами-стоматологами навыков объемного моделирования, что является обязательным условием высокого качества эстетических работ. В разработанных четырех практикумах представлены этапы освоения навыков формообразования. На первом этапе основной задачей обучения является формирование высокой объективной оценки восприятия формы, размеров и рельефа зуба. На следующем этапе стоматологов обучают изображать простейшие формы в виде плоских фигур, затем осваивать навыки изображения на плоскости срезов объемных предметов, в том числе зубов. Последующее обучение направлено на воспроизведение объема трехмерных тел, в том числе зубов. Заключительный этап включает моделирование зуба в 3D-проекции, воссоздание групповой принадлежности зубов, макро- и микрорельефа, индивидуальных черт, а также послойного воспроизведения дентина и эмали в зависимости от возрастных изменений морфологии зубов пациента.

To carry out restoration work that meets the requirements of modern aesthetic dentistry, the Belarusian Medical Academy of Postgraduate Education Department of Therapeutic Dentistry has developed workshops aimed at the phased, consistent development by dentists of volumetric modeling skills, which is a prerequisite for high quality aesthetic work. The developed four workshops present the stages of mastering shaping skills. At the first stage, the main task of training is to form a high objective assessment of the perception of the shape, size and relief of the tooth. At the next stage, dentists are trained to depict the simplest shapes in the form of flat figures, then learn the skills of image on the plane of sections of volumetric objects, including teeth. Subsequent training is aimed at reproducing the volume of three-dimensional bodies, including teeth. The final and final stage involves modeling the tooth in 3D projection, recreating the group belonging of the teeth, macro- and micro relief, individual features, as well as layer-by-layer reproduction of dentin and enamel depending on age-related changes in the morphology of the patient’s teeth.
PSEUDOMONAS FLUORESCENS IN SHEEP MILK GREEK YOGHURT FROM VLASINA – A BIOCHEMICAL CHARACTERIZATION
Authors: Tasić Srđan , Janjić Aleksandar
Published: November 2022

Pseudomonas fluorescens is an aerobic, rod-shaped, non-sporulating gram-negative bacteria, mostlyfound in soil, decaying organic matter and feces. This species contaminates the milk mainly through animal feeddust, silage, utensils and polluted water. In addition to casein digestion, this psychotropic and lipolytic speciesgenerates butyric and caproic acids by fermentation of milk fat, which release a strong unpleasant odor and give arancid and bitter taste to dairy products. In this study we tested 48 hours old sheep's sour milk, produced in ahousehold in Vlasina, southeastern Serbia, using traditional method. Standard bacteriological protocols were usedfor isolation and identification Pseudomonas fluorescens strains. Biochemical identification was performed usingthe commercial API 32GN E system, and 60473057073 profile was obtained (Pseudomonas fluorescens, %Id=99.5and T=0.74). Positive biochemical tests were: N-acetyl-glukosamine (NAG), D-Ribose (RIB), Sodium malonate(MNT), Sodium acetate (ACE), Lactic acid (LAT), L-Alanine (ALA), D-Mannitol (MAN), D-Glucose (GLU), LArabinose(ARA), Capric acid (CAP), Valeric acid (VALT), Trisodium citrate (CIT), L-Histidine (HIS), Potasium2-ketogluconate (2KG), 3-Hydroxybutyric acid (3OBU), 4-Hydroxybenzoic acid (pOBE), L-Serine (SER), LProline(PRO) and Oxidase (OX). Negative biochemical tests were: L-Rhamnose (RHA), Inositol (INO), DSaccharose(SAC), D-Maltose (MAL), Itaconic acid (ITA), Suberic acid (SUB), Salicin (SAL), D-Melibose (MEL),L-Fucose (FUC), D-Sorbitol (SOR), Propionic acid (PROP), Potasium 5-ketogluconate (5KG), Glycogen (GLYG)and 3-hydroxybenzoic acid (mOBE). Based on the example of the strain Pseudomonas fluorescens, the API ID 32GN system proved to be precise and very efficient in the identification of this lipolytic type. Given thatpasteurization and cooling processes do not entirely inhibit the enzym activity and growth of this psychotrophicbacteria, informing individual milk and milk product manufacturers in the Vlasina region about good manufacturingpractices would limit contamination and bacteriological deterioration.
EFFECT OF COLLAGEN INDUCED ARTHRITIS ON ANTISTREPTOLYSIN TEST IN THE WHITE LABORATORY RAT
Authors: Spasov Mire , Gjorgoski Icko
Published: November 2022

Rheumatoid arthritis (RA) is a serious health challenge as a disease with serious health consequences andthe potential to result in permanent disability. Most of the authors state that the reason for the occurrence of thedisease and its persistence is multifactorial, but above all it is a genetic predisposition as a result of the disruption ofthe control mechanisms of the immune system. The disease can occur at any age, but it is most common in patientsover sixty years of age who suffer from damage to the joints, resulting in impaired locomotion, reduced workcapacity, unproductive and poor quality of life. Animal models in RA disease research are useful for studying andevaluating the effect of potential antiarthritic drugs. The study of the disease in animal models provides usefulinformation about rheumatoid diseases and RA in humans because of the great similarity in their onset anddevelopment.Our research aimed to see how collagen type-II induced arthritis would cause an effect on the immune system andinter alia on ASTO in Wistar rats of both sexes, on the thirtieth and sixtieth days of immunization. ASTO is alsoused to diagnose RA secondary to streptococcal infections. Wistar rats, healthy seven-week-old male and femaleanimals, bred according to standard conditions for experimental animals at the laboratory animal farm at PMFSkopjewere used for the research. The experimental animals were divided into four groups; control group of maleanimals (n=20), control group of female animals (n=20), experimental group of male animals (n=30), which weretreated with collagen type-II and experimental group of female animals (n=30), which were also treated withcollagen. Analyzes of aliquots were performed on the thirtieth and sixtieth day of the test. We apply the highlypurified collagen type-II according to a defined protocol in the joint of the back right leg. We took blood for analysison the thirtieth and sixtieth day after immunization. The ASTO samples were tested on the computerized andthermostated Mini NEF TM Duinding Fait apparatus. The principle of the method is based on the fact thatpathogenic beta-hemolytic streptococci of group A produce streptolysin O, which stimulate the body to produceantistreptolysin. A titer greater than 1/200 is a positive value. From the studies that were done on the influence ofcollagen induced arthritis type-II on the value of ASTO in both sexes of animals, in both experimental periods, it canbe concluded that they are within the limits of normal values in all groups and in both sexes. All were <59,430IU/ml. In general, these studies of RA performed in animal models provide a good parallel for the course anddevelopment of RA in the human population.
PROBABILITY DENSITY FUNCTION OF AVERAGE POWER OF REAL SPEECH SIGNALS
Authors: Petković Goran
Published: November 2022

It is known that many real signals, such as speech signals, are non-stationary processes that express theirfeature through changes in parameters over time. By observing speech in shorter time intervals, the property ofstationarity can be notice. This characteristic enables the application of techniques for adaptation to local signalcharacteristics in signal processing algorithms. Many of these algorithms are described by standards, and in additionto intensive development in this area in last decades, there is a constant need for the development of new solutionsand standards. One of the most used parameters of the speech signal for adaptation is the mean (average) signalpower. The change of speech in time results in a wide dynamic range of average power. In addition to the predicteddynamics of average power, in the design of systems with adaptive techniques it is important to include otherparameters, among which is the Probability Density Function (PDF) of the average power. The goal of the researchpresented in this paper is the analysis of the probability distribution of the average power of speech signals, based onwhich the adaptability in the development of algorithms in digital processing would be improved, which wouldensure higher quality and less requirements in data transmission and storage. In addition to the theoreticalconsideration, the research was conducted on real speech signals of different speakers. In modern technical systems,where Internet technologies are prominent, processing, transmission and memorization of speech is executed frameby frame. Therefore, an analysis of the probability density of the average power for different frame lengths wascarried out in the experiment. In the experimental part, for each of the speech signals of the speech corpus, theProbability Density Function that best describes the average power values per frame was determined. Experimentalresearch results indicate that the function that best describes the average power is different for different speakers. Inaddition, when observing one speaker, the Probability Density Function is different for different frame lengths. Itcan be concluded that when it comes to adaptive techniques in the digital processing of the speech signal, it isimportant to consider the characteristics of the average power, among which is the Probability Density Function ofthe average power

Authors: Fadel Ibrahim A. , Öz Cemil
Published: November 2022

In this paper, the dataset of real incidents that occurred in Turkey between 2013 and 2017 and are regarded as acts of terrorism without any doubt according to Global Terrorism Database (GTD) are used to predict the group names responsible for unknown attacks. Principal Component Analysis (PCA) technique was used for feature selection. A novel voting method between five classification algorithms such as Random Forests, Logistic Regression, AdaBoost, Neural Network, and Support Vector Machine was used to predict the names. The results clearly demonstrate that the classification accuracy of all classifiers studied in this paper improved when PCA was used to select features as compared to selecting features without using PCA. The prediction of terrorist group names with PCA based feature reduction and the original features is carried out and the results are compared.
A literature review: Wind energy within the scope of MCDM methods
Authors: EROĞLU Özer , AKTAŞ POTUR Ezgi , KABAK Mehmet , GENCER Cevriye
Published: November 2022

Renewable energy sources (RES) are vital for environmental sustainability. With the depletion and damage of fossil fuels to nature, energy production from clean and inexhaustible RES has become widespread. Wind energy, one of the RES, is a clean energy source that does not emit any harmful waste to the environment. Wind energy is a low-cost energy source that is mostly used for electricity generation. Criteria such as wind speed, turbine structure and the characteristics of the areas where the wind turbines will be located are effective on the amount of energy to be produced. In this study, a comprehensive review of the studies using MCDM methods related to wind energy is made. In the manner of the statistical data obtained from the 97 studies examined, it has been observed that the wind energy investments and the scientific publications made in these countries do not progress linearly with each other. The fact that countries have different wind energy potentials and the difference in the countries' interest in RES is thought to be effective in this regard. While there are articles in the literature in which studies on RES are discussed together with MCDM methods, there is no comprehensive review study in which wind energy and MCDM methods are discussed together. According to our best knowledge, this is the first study to comprehensively evaluate wind energy studies in terms of MCDM methods. With this study, a framework has been presented for subsequent studies on the application of MCDM methods in wind energy.

Published: November 2022

In this work, the formulation of composite materials of Recycled Irrigation Tape and Corn Stover (r-IT/CS) with additives, were studied. The variables analyzed were the size effect and the percentage of fibers. The r-IT/CS composites were processing in a twin screw extruder and compression molded. The materials characterization were by tension, bending, impact, hardness, and DSC measurements. As the fiber concentration and length increased, modulus, resistance (tension and bending), and hardness increased, but impact resistance decreased in comparison with the r-IT matrix. The percentage of crystallinity decreased by 4% with the addition of the CS fibers. The properties of the composite materials were similar to those of the polymeric matrix. These results open the possibility of using them as packaging.

Published: November 2022

This work documents the use of communication finite state machines for the representation of interactions in a network of devices. Likewise, a hierarchical structure between elements is adopted, under an organization of master-slave nodes; from which, the implemented communication protocol assumes the particular functions of each device, while ensuring the exchange of information between them. In order to validate the adequate constitution of the proposed protocol, through its respective programming, Arduino and Raspberry free hardware and software are used, as well as a basic interface created from the Thonny development environment, for data entry by the user and the feedback of information to this. The results obtained demonstrate the functionality of the developed protocol, which was implemented from the serial communication standard, supported by the hardware used. However, it is essential to clarify that it is possible to implement this type of application from the use of other standards, as available.

Published: November 2022

The main objective of this study is to determine whether there is a relationship between the level of persistence in completing assignments and students' potential. The design used in this study is quantitative research. This study utilized data from the AKM 2020 SMA / SMK examination results held by Pusmenjar. This study's population is the satisfaction level of SMA / SMK students studying with teachers at school in 2020, while the sample is the degree of satisfaction of SMA / SMK students taking the 2020 AKM exam. SMA / SMK participants of AKM 2020 (514 districts/districts in 34 provinces in Indonesia). Based on the results of simple regression and part analysis, the following results were obtained. Even though the contribution is not particularly large—0.14% to be exact—statistically speaking, there is a positive relationship between the level of tenacity in finishing activities and one's self-potential (P 0.05). The health of students in understanding the material is most influenced by (1) feelings of nervousness or anxiety (-0.015), (2) getting carried away or easily angry (-0.016), (3) insomnia (-0.018), and deep feelings of sadness. Or depressed (-0.094). The contribution of the four variables (anxiety, anger, insomnia, and sadness) to students' health is relatively high, 0.605 (61%), while other variables influence the remaining 39%. The relationship between student health and subject matter is 0.286 (29%). The findings lead us to conclude that there is a statistically significant correlation (P 0.05) between the degree of students' self-potential and the amount of effort they put into finishing their tasks.

In data collection, this study used open-ended questionnaires given to all participants, while semi-structured interviews were delivered to 11 representative students. Students’ Haiku also were used as additional data. In addition, the data were analyzed thematically, using the framework of Braun and Clark (2006) and students’ Haiku were analyzed through document analysis. The findings show that students find that writing haiku as a learning reflection is fun and interesting. It also promotes their creativity in writing.

Eventually, Haiku still supports creativity, not effectiveness.
