Published: February 2022

O ensino de Biologia Celular enfrenta desafios no aprendizado dos alunos sobre processos e conceitos microscópicos difíceis de serem compreendidos. As metodologias ativas, como jogos e modelos didáticos, são utilizadas na tentativa de aproximar os conteúdos do entendimento deles. Portanto, neste trabalho, foi desenvolvida e aplicada uma intervenção educativa sobre Biologia Celular para alunos do primeiro ano do Ensino Médio de uma escola pública da rede federal de ensino do município de Floriano-PI. A intervenção foi composta de dois momentos: (1) uso de modelos didáticos durante uma exposição dialogada e (2) aplicação das provas “Gincana da Célula” como forma interativa de avaliar o conhecimento adquirido pelos alunos. Os dados obtidos a partir de questionários aplicados antes (pré-teste) e após (pós-teste) à execução da intervenção, foram avaliados quanto ao ganho normalizado de aprendizagem (g). A avaliação demonstrou uma progressão do conhecimento total alto (g = 0,82).  Sobre a aula dialogada, 96,6% dos alunos afirmaram ter gostado por ter sido dinâmica, interativa e bem ilustrada. Quanto à gincana, 96% afirmaram que a proposta promoveu integração do aprendizado. Essa experiência foi enriquecedora, pois fez com que os alunos ficassem mais atentos ao que estava sendo explicado e souberam aplicar bem o que aprenderam.

Authors: Krug Carbone Bruno Schmidt , Nogueira Clélia Maria Ignatius
Published: February 2022

O objetivo deste estudo foi realizar um levantamento da presença das ideias base de função na apresentação do conteúdo matemático função afim pela coleção “Contato Matemática”, aprovada pelo PNLD 2018. Foi realizada uma pesquisa qualitativa, à luz da Teoria dos Campos Conceituais, reconhecendo a importância do conceito de função na Educação Básica e o livro didático (LD) como principal material pedagógico acessível ao professor, na intenção de identificar se são propostas situações-problema envolvendo função afim, que possibilitam a mobilização das ideias base de função (correspondência, regularidade, variável, dependência, generalização).  Os resultados indicam que tanto na parte teórica quanto nas atividades resolvidas e propostas, nem todas as ideias base estão contempladas, tanto quantitativa quanto qualitativamente. A análise permite inferir que o LD considerado precisa ser complementado pelo professor, com conteúdo teórico e atividades práticas para o ensino e a aprendizagem do conceito função afim.

Published: February 2022

Pembangunan e-Government telah dilakukan baik pemerintah daerah maupun pemerintah pusat. e-Government pada intinya adalah penggunaan teknologi informasi oleh suatu pemerintah daerah maupun pusat untuk meningkatkan pelayanan publik menjadi lebih nyaman, cepat , murah dan transparan. Namun b anyak ditemui bahwa kondisi pemanfaatan teknologi informasi untuk pemerintah ini belum mampu memberikan nilai tambah bagi organisasai. Beberapa kegagalan proyek teknologi informasi di pemerintah tersebut disebabkan oleh beberapa faktor, antara lain kuantitas dan kualitas sumberdaya manusia yang menjalankan implementasi teknologi informasi pada e-Government sangat terbatas, belum tersedianya sarana dan prasarana yang memadai, struktur organisaasi pengelolaan e-Government yang belum memadai dan belum tersedianya anggaran operasional yang memadai juga. Untuk mendapatkan hasil yang baik, maka pembangunan e-Government harus dilaksanakan secara terkoordinir, terencana sesuai kebutuhan . Peran pemerintah pusat maupun propinsi menjadi koordinator pelaksanaan e-Government sangat penting karena kunci suksesnya pelaksanaan e-Government adalah tersambungnya kebutuhan masing-masing pihak baik masyarakat, steak holder maupun pemerintah dalam satu kepentingan. Selain sarana dan prasarana jaringan, sumberdaya manusia yang handal maka budaya kerja yang masih tradisional juga perlu dirubah secara sistematis agar mereka terbiasa dan dapat menyesuaikan dengan perubahan.

Published: February 2022

Candida-associated nosocomial infections are a persistent problem which has been steadily increasing over the years. The emergence of antimicrobial resistant strains has narrowed the spectrum of effective drugs that can be utilised and indicated the need for alternative therapeutics. Garlic is a spice often studied for its unique characteristics. Most of its antimicrobial properties have been attributed to the presence of allicin, which makes up more than 70% of thiosulfinates extracted from garlic. The present study aimed to determine the effects of fresh garlic extract (FGE) towards the expression of two major biofilm genes, Flo-8 and Ndt80 produced by C. albicans that enable the morphogenesis of yeast from planktonic cells to biofilm.  Minimum concentration required for FGE to inhibit C. albicans was determined through agar well and disc diffusion assay. Effect of FGE towards preformed C. albicans biofilms was evaluated at ¼× and ½× inhibitory concentrations of FGE and Amphotericin B, respectively by XTT assay. RNA from FGE-treated C. albicans was extracted, reverse transcribed and analysed by Real-Time Polymerase Chain Reaction (RT-PCR) to determine FGE effects towards the expression of Flo-8 and Ndt80. Inhibitory concentration of FGE was determined to be 100 mg/mL. Both genes appeared to be upregulated in the presence of FGE with a higher upregulation noted with Flo-8 (67.34 and 30.20-folds) when compared against Ndt80 (5.55 and 1.79-folds) at 5 mg/mL and 10 mg/mL, respectively. It is surmised that C. albicans upregulated these genes as a survival mechanism in the presence of FGE. The findings from this study indicate that FGE could inhibit C. albicans growth and biofilms. Further research is required to determine the minimum inhibitory concentration (MIC) through broth microdilution and to understand the mechanism behind this phenomenon before it can be utilised as a potential therapeutic to combat Candida-associated nosocomial infections.

Authors: Riadi Imam , Ifani Aulyah Zakilah , Kusuma Ridho Surya
Published: February 2022

User data security innovation is a particular concern in protecting one's privacy rights, which is one of the serious violations when an attacker can bypass the user authentication so that it looks like something legitimate and becomes legal. Based on these issues, the research aims at optimizing and evaluating the blockchain-based authentication systems to minimize data leakage, manipulate the data, and modify the data. Blockchain is one of the innovations that can solve this problem. Data or transactions in the blockchain are saved in hash form to make it difficult for hackers to break into them. The Blockchain implementation uses the Solidity programming language to build smart contracts and other tools such as MetaMask, Ganache, and Truffle. The Network Forensics Development Life Cycle (NFLDC) is used as a framework with the following five stages: Initiation, Acquisition, Implementation, Operation, and Disposition. Based on the research conducted, the attack strategy against blockchain-based systems consists of several scenarios covering the Burp Suite, XSS, SQL Injection, and DoS. The results show that the percentage of authentication optimization reaches a value of 90.1%, and 8.9% is the percentage for evaluating systems such as the possibility of cyberattack. Based on these results, this research has achieved its goals and may assist in further research. Doi: 10.28991/esj-2021-SP1-015 Full Text: PDF
3D Numerical Modeling to Evaluate the Thermal Performance of Single and Double U-tube Ground-coupled Heat Pump
Authors: Tarrad Ali H.
Published: February 2022

The heat transfer rate and borehole design represent great challenges to the thermal equipment designer of the ground-coupled heat pump. The present model represents a mathematical and numerical technique implemented to tackle such a problem. A thermal assessment was established to estimate the total energy dissipated to the ground zone for a heat pump utilized for cooling purposes in the summer season. Comsol Multiphysics 5.4 software was used to build a 3-dimensional model to assess the thermal performance of single and double U-tube boreholes that circulate water as a thermal transfer medium. The (Heat Transfer) module has been implemented for this investigation under the (Stationary) study option. The model couples both heat conduction in solids, including tube metal, grout, and soil regions, and thermal medium fluid flow inside the U-tubes. The numerical solutions were compared for both heat exchangers at fixed borehole geometry, diameter, and depth and constant operating conditions in a steady-state mode. The double U-tube heat exchanger was tested in the parallel circuiting orientation of the U-tubes. The total mean resistance of the single U-tube borehole was higher than the half-loading double U-tube heat exchangers by 14.6%. The results also revealed that the heat transfer rate enhancement for the double U-tube was in the range of 10–14% when operating at the same fluid mass flow rate and inlet temperature for a given borehole design. Doi: 10.28991/HIJ-2022-03-02-01 Full Text: PDF
Cohesive Methodology in Construction of Enclosure for 3.6m Devasthal Optical Telescope
Authors: Bangia Tarun , Raskar Ramesh
Published: February 2022

Building telescope enclosures is vital for setting up any optical observatory. An enclosure was constructed in remote hilly terrain to provide shelter to India’s largest 3.6 m Devasthal Optical Telescope (DOT). Primarily, the enclosure was built to protect the telescope from tough weather conditions and provide optimum space for performing various telescope related operational and maintenance activities. Other elements that were considered in the building enclosure were low thermal mass, sustainability, seismic and acoustic considerations. A steel building designed with mostly bolted connections, suitably selected materials, and mechanical systems for facilitating construction activities on site has been built for the telescope at the Devasthal site of ARIES. The enclosure construction was quite a challenging task with various project complexities. Multidisciplinary works of civil, mechanical and electrical systems in enclosure required efforts on various fronts in parallel to achieve the targets. Limitations of resources, manpower, and site conditions were managed to keep flexibility and economics in construction. Numerous challenges faced during the making of enclosures have been discussed in the paper. Insights into the construction of enclosures will provide a basic framework and learning opportunities for managing such typical construction projects in adverse weather conditions at mountainous sites. Doi: 10.28991/HIJ-2022-03-02-05 Full Text: PDF
Analytical Investigation of Higher Education Quality Improvement by Using Six Sigma Approach
Authors: M. S. Ameen Abdulla , E. G. Kavilal
Published: February 2022

For over two decades in India, the technical industry's unique selling proposition (USP), with its wide infrastructure of technical institutes, has been capable of supplying best-in-class engineers. But recently, this claim does not hold water. According to the All India Council for Technical Education (AICTE), about 2.6 lakh mechanical engineers graduate every year in India. But the real count of industry ready mechanical engineers is approximately 7%. Hence, there is a need to assess the quality of engineering education in India to reduce the flaws in higher education. The purpose of the paper is to identify the various defects associated with technical education and eliminate those defects using various quality tools. This research is based on the six sigma technique, which is used to assess the quality criteria proposed by the National Board of Accreditation India (NBA). The proposed model is then applied to a typical tier II Indian engineering college located in south India. Six Sigma has two main methodologies: DMAIC and DFSS. The DMAIC (Define, Measure, Analyze, Improve, and Control) methodology is implemented for existing systems, whereas DFSS (Design for Six Sigma) is for assuring quality in new products. In this project, the conclusion is driven by the DMAIC methodology. Various statistical and non-statistical tools are employed in this research. The tools used are CTS-CTQ, SIPOC, Pareto chart, normal process capability analysis, one-way ANOVA, Ishikawa diagram, FMEA, RCBD, and SPC chart. All the statistical processes are done using Minitab analytical software. From the results, it is identified that the factors that have a risk priority number (RPN) greater than 300 need improvement, such as versatility in program curriculum, laboratories and workshops, and credibility among universities. Six Sigma can be achieved by developing proper strategies for mitigating these defects. Doi: 10.28991/HIJ-2022-03-02-07 Full Text: PDF

Authors: Kien Pham Huu , Nhu Tran Thi Quynh , Trang Giap Thi Thuy
Published: February 2022

We have performed a simulation of the structural transition and Structural Heterogeneity (SH) in liquid Al2O3 at 3500 K, in the range of 0–100 GPa. The results confirmed that the network structure of liquid alumina is built mainly from AlOx (x = 3, 4, 5, 6, 7) units, which are related to each other through the common oxygen atoms. The existence of separate AlO3-, AlO4-, AlO5-, AlO6- and AlO7- phases, where SH of the network structure can be sufficiently determined, besides, the existence of separate phases is clarified for SH in the liquid of Al2O3. In particular, at a pressure below 10 and beyond 20 GPa, AlOx units are uniformly distributed in the space and non-uniformly distributed in the range 10-20 GPa. Our study is expected to contribute to a simple way to determine the structural heterogeneity and diffusion coefficients of oxide systems. Doi: 10.28991/HIJ-2022-03-02-08 Full Text: PDF

Biblioterapia na produção científica strictu sensu no Brasil
Authors: Moreira Cristiano , Hamanaka Raíssa Yuri
Published: February 2022

Percebe-se que qualquer área do conhecimento, desde a sua gênese, norteia-se com base em paradigmas moldados pelas transformações sociais. Diante deste cenário, a profissão do bibliotecário vem sofrendo também inúmeras transformações oriundas das necessidades que envolvem seus usuários. A Biblioteconomia pode ser entendida como um campo científico que se preocupa em dar acesso a documentos, sendo caracterizada pelo enfoque material (das coleções  de documentos), enfoque organizacional (relacionado a infraestrutura física e administrativa da biblioteca), enfoque  intelectual (tratamento informacional dado aos documentos para que possam ser recuperados) e o enfoque do usuário.  Neste sentido, surge como uma nova possibilidade de atuação a biblioterapia que consiste na adoção da leitura no tratamento de pacientes com algum tipo de transtorno psíquico ou psicológico. Por ser um ramo de atividade do  bibliotecário ainda pouco explorado, pretende-se responder à seguinte questão de pesquisa: como a biblioterapia tem sido abordada na produção científica strictu sensu no Brasil? A pesquisa é caracterizada como qualitativa, com objetivos  exploratório e descritivo e avaliou as teses e dissertações disponíveis nas bibliotecas digitais de teses e dissertações da  Capes e do Ibict. Com a análise dos resultados, foi possível concluir que a biblioterapia tem sido pouco explorada na  Ciência da Informação, o que demanda um esforço conjunto de pesquisadores e instituições de ensino para consolidar o  estudo desta disciplina na perspectiva do bibliotecário.

Maisexplorado nas Ciências Sociais, o assunto registra baixa colaboração internacional e desenvolve-se em torno de temáticas centrais como teletrabalho, saúde, educação e Covid-19. Conclui-se que o impulso recebido pelo assunto na pandemia de Covid-19 tende a ampliar e diversificar as pesquisas e as discussões sobre o home-office como forma de trabalho de caráter provisório, excepcional ou sistemático na sociedade contemporânea.
Halit Ziya’nın romanlarında tabiat algısı
Authors: ŞENGÜL Servet
Published: February 2022

Halit Ziya’nın romanları Türk edebiyatında bir başlangıcı temsil eder. İlk romanlarını Tanzimat edebiyatı yıllarında kaleme alan yazarın romanları içerik ve şekil açısından Tanzimat’ın diğer romanlarıyla benzerlik gösterir. Türk edebiyatının modern romanları ilk kez Mai ve Siyah, Aşk-ı Memnu gibi romanlarla Servet-i Fünun devrinde edebiyatımıza girmiştir. Tanzimat’ın teknik yönden zayıf romanları yerini, her bakımdan gelişmiş olan bu romanlara bırakmıştır. Halit Ziya’nın romanları teknik anlamda zayıflıktan kuvvetliliğe, romantizmden realizme geçiş yaparak Batı’daki emsalleriyle yarışacak değere ulaşmıştır. Tabiata ilk olarak duygusal bakan yazar, sonraki romanlarında tabiatı, güçlü realistler gibi romanını geliştirmek maksadıyla kullanmıştır. Tekniğini bu denli hızlı geliştiren bir yazarın ‘tabiat algısı’ yönü eserlerinin gelişimini göstermesi bakımından önemlidir. Yazarın romanlarında dönemin içe kapanık psikolojisinin karakter ve tabiat ilişkisine nasıl yansıdığı metin tahlili bakımından incelenmeye müsaittir. Bu çalışmada Halit Ziya’nın Tanzimat ve Servet-i Fünun dönemlerine ait beş romanı tabiat algısı yönünden incelenerek yazarın tabiatı nasıl algıladığı ve bu algının karakterlere nasıl yansıdığı araştırılacaktır.

Published: February 2022

Warming meal at educational centers for students is done with microwave ovens consuming high energy and making long queue. Conventional hot box solar ovens can warm meal using free, abundant and clean Solar energy, during 10-11 months in a year in many places in Costa Rica. For the rest of the periods, if heating is required one can use Microwave Ovens. Different types of pots which can be used both in Solar and Microwave ovens have been searched and are studied. Due to pandemic period experiments have been done at authors house for measuring oven, meal temperature with solar radiation and with different pots. The heating of 14 lunch boxes is done with one solar oven and even simulating the clouds to see the performance and results are very promising. Due to COVID during 2020 and 2021, the classes were virtual, thus the real heating could not be done in any college to see the acceptance by the students and staff. We plan to promote see the real performance during 2022.

Published: February 2022

The Lubuksikaping area is located between the main fault branching of the Sumateran Fault so it can be seen that there are many quite complex structures. This research was conducted to determine the structure pattern of the high (horst) and low (graben) that formed in the sub-surface of the Lubuksikaping area, West Sumatera. This research uses gravity data which will then be carried out by spectral analysis, upward continuation, separation of regional and residual anomalies, and Second Vertical Derivative (SVD) analysis. Furthermore, 2D forward modeling is carried out to determine the correlation between the 2D subsurface forward modeling and the resulting SVD graph. Based on the analysis of the regional anomaly map, it can be seen that the measured low anomaly is due to the area in the form of a structural valley formed due to the activity of the Sumatera Fault, while the high is thought to be a structural hill (horst) that forms an elongated mountain range and separated by graben. In addition, based on the analysis of the residual anomaly map, it can be seen that the low anomaly indicates the presence of a depositor (graben), whereas, the high anomaly is indicated as the presence of rocks with high-density contrast values. and is interpreted as a horst structure. Based on the analysis of the horst and graben patterns in the residual Bouguer anomaly, it can be seen that there is an elevation zone (horst) that are northwest and northeast on the residual map and it is known that there are 3 graben structures in Lubuksikaping, namely Panyabungan Graben, Rao Graben and Sumpur Graben with relative northwest-southeast direction. The 2D models of paths A-A' and B-B' show faults that are located relatively the same as the SVD graph obtained from the residual SVD anomaly map.

Published: February 2022

The research has measured the landslide using a displacement sensor based on Glass Optical Fiber (GOF) and Optical Time Domain Reflectometer (OTDR). The sensor manufacture process consists of various materials, structures, configurations, diameters, and directions. The sensor is made using GOF with a single-mode structure and single mode-multimode-Singlemode (SMS) structure. Each system is given a variety of configurations, namely gamma, bowknot, and three loops configuration. Each arrangement is provided a variation of the indentation diameter in three displacement directions. The test results will be read as the power loss on the OTDR in dB units. The results obtained were then compared between two materials, two structures, and directions. Displacement resulting landslides and changes to the sensor, causing power losses, and affecting the characteristics of each sensor. We found the best measurement results with the sensitivity value of 0.241 dB/mm and the resolution value of 0.004 mm. The displacement sensor has been made for measuring landslide in the laboratory-scale simulation based on GOF and OTDR with easier fabrication, easy operation, high sensitivity, better resolution and can be connected to a computer
EFFECT OF NIGELLA SATIVA EXTRACTS IN LIVER CELL OF RATTUS NORVEGICUS INDUCED BY PIROXICAM
Authors: Kurniasari Septiana
Published: February 2022

Piroxicam has the potential to cause side effects, especially in the liver, so that it can causes cell damage and impair the function and work of the liver organs. One way to minimize liver cell damage is by giving black cumin (Nigella sativa). This study aims to analyze the effect of black cumin (Nigella sativa) extract on the level of liver cell damage in rats (Rattus norvegicus) induced by Piroxicam. This study used 80 male rats and divided into 3 groups, namely negative control (K-), Piroxicam non-extract (P-) and Piroxicam plus extract (P +). Black cumin extract is given orally at a dose of 2 gr/kgBW; 3 gr/kgBW; 4 gr/kgBW; 5 gr/kgBW and 6 gr/kgBW, while the Piroxicam dosage given is 1 g/kgBW and 3 g/kgBW. The liver cell damage was done by observing the microscopic image. The results showed that the more doses of Piroxicam were given, the higher the level of cell damage. Along with increasing the dose of black cumin extract, the cell damage is reduced.

Authors: Ramadhani Ahmad Ilham , Noerochim Lukman , Susanti Diah , Sari Eli Novita
Published: February 2022

Olivine single phase of LiFePO4 was successfully synthesized by solid-state reaction (SSR) method through the formation of Fe2P2O7 from precursors of Li2CO3, F2O3, NH4H2PO4, and LiF as materials doping. Variations at temperatures of calcination 670 0C, 700 0C and 750 0C with doped 0.1F. TGA-DSC test results show that the LFP sample undergoes decomposition in the temperature range 0-600 0C. The olivine phase formed at temperatures of more than 650 0C and the oxidation process on the LiFePO4/C sample was completed, and the sample mass was constant. The olivine phase formed was determined by comparing the 2𝜃 value obtained through characterization with the ICDD LFP (01-081-1173), and accordingly with experiment. The increase of the temperature results from a dominant LFP phase with a larger grain size. The effect of increasing the calcination temperature at 0.1F has resulted in an enlargement of the particle size.

The statistical distribution of the patients' demographic and clinical information was calculated.Results: The most common complaint of 206 patients with acute pulmonary embolism was dyspnea. 25.7% patients had massive pulmonary embolism. The blood d-dimer, lactate and troponin T levels of patients with massive pulmonary embolism were found to be higher than patients with sub-massive pulmonary embolism. Thrombolytic therapy was administered to 6.8% of acute pulmonary embolism patients and it was found to be a method that had a statistically positive effect on survival. D-dimer, white blood cell, neutrophil, blood urea nitrogen, lactate and troponin T values were found to be higher in mortal patients. It was determined that 13.1% of the patients died.Conclusion: The sooner the early diagnosis of acute pulmonary embolism, which can be mortal in the emergency department, is made and the treatment is started, the mortality rate will decrease significantly.

Aim: The aim of this study was to evaluate the clinical and radiological results of Ludloff medial open reduction surgery in patients with the developmental of hip dysplasia, younger than 18 months old.Methods: The radiological and clinical results of 35 patients (49 hips), younger than 18 months of age treated with Ludloff medial approach due to DDH between the years 2013 and 2020 were retrospectively evaluated. Preoperative, final control acetabular index angles and medial apertures were measured according to the McCay criteria, Tönnis classification, Kalamchi-MacEwen classification, IHDI classification and Severin classification were analysed.Results: At the last control, the youngest age was 27 months, the oldest was 88 months and the mean age was 43.90 ± 14.17 months. The follow-up period was performed at a minimum age of 12 months, a maximum age of 72 months, and the mean follow-up period was 24.81 ± 17.17 months. According to the Tönnis classification, 40 hips were Tönnis classification type 1 (81.63%), 4 hips were Type 2 (8.16%), 3 hips were Type 3 (6.12%) and 2 hips were Type 4 (4.08%) in the follow-up visit. According to McCay clinical evaluation criteria, 38 hips (79.59%) were grade 1 which equates to excellent results. Grade 0 (no necrosis) was detected in 38 (77.55%) of 49 hips according to the Kalamchi and MacEwen AVN clinical evaluation criteria. According to the Severin classification, type 1 results were observed in 32 (65.31%) of 49 hips, type 2 in 9 hips (18.37%), type 3 in 1 hip (2.04%) and type 4 in 7 hips (14.29%). The mean CE angle was found to be 18.56 ± 9.93. Additional surgical intervention was required in 8 hips of 6 patients.Conclusion: Clinically and radiologically satisfactory results were obtained in DDH patients with Ludloff medial open reduction technique, below the age of 18 months.

Authors: KANKILIÇ Nazım
Published: February 2022

Aim: Carbohydrate antigen-125 (CA-125) is a well-known marker for mesenchymal cell activation. It is being investigated as a predictive marker for cardiac pathologies due to pericardial or pleural mesenchymal cell activation. In this study, the relationship between left ventricular diastolic diameter (LVDd) and ejection fraction (EF) and serum CA-125 levels was investigated.Method: Thirty-eight patients who underwent coronary artery bypass graft operation were included in the study. LVDd and EF values were calculated. Routine blood parameters and serum CA-125 levels were obtained from blood samples. Patients were divided into groups according to LVDd (LVDd <50mm vs. ≥50mm) and EF (EF <50% vs. EF≥50%).Results: Among the low (<50%) and high (≥50%) EF groups, serum neutrophil, mean platelet volume (MPV), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), troponin-I, triglyceride, and very low density lipoprotein (VLDL) levels were statistically different (p<0.05). However, no statistical difference was observed between the low (<50mm) and high (≥50mm) LVDd groups in other blood parameters except for serum CA-125 levels (p>0.05). Higher serum CA-125 levels were obtained in patients with a high left ventricular diastolic diameter (≥50mm) (p<0.05). In addition, CA-125 was found to be an important predictor of left ventricular diastolic diameter with an optimal cut-off value of 0.644 kU/L (60% sensitivity and 78.3% specificity).Conclusion: According to our results, increased serum CA-125 level is an independent predictor of higher LVDd and may be a good indicator of left ventricular functions.

Published: February 2022

Mathematical literacy prepares future generations to deal with the challenges of a changing world. But, students' knowledge and abilities are still below the optimal level. This study aims to evaluate how students' learning habits, which are based on the chronology of time and cognitive processes, affect their mathematical literacy. This quantitative study employs an observational approach with vocational students in West Java who participated. This study examines the measurement and structural model up to the second-order levels. The findings revealed that the habit of reviewing had a substantial impact on factors in formulating mathematical models. However, the other components were not. Indications of how students adapt information lead to the condition that they do, but not in an ideal way at the logical-operational level. Therefore, learning is insufficient only during school hours due to cognitive capacity considerations, while the other is to build an independent learner attitude outside of school.

This study aims to describe the process of solving mathematical problems in the subjects of a two-variable linear equation system in terms of field-dependent cognitive style. The type of research used is descriptive qualitative research. The research subjects were 15 grade VIII students in one of the public junior high schools in Cimahi City. In this study, the instrument used was a problem-solving test consisting of 2 questions on the material of a two-variable linear equation system and interviews for 3 students with field dependent cognitive style. The results showed that the steps of solving mathematical problems of students with cognitive style field dependent were categorized as good at the stage of understanding the problem and re-examining, categorized enough at the stage of planning completion, and categorized less at the stage of implementing the completion plan. This means, if field dependent students can understand the problem or problem, it will affect the next step.
Stories of Our Fellow Mathematics Tutors during Covid-19 Pandemic

Published: February 2022

The tutoring phenomenon has been discussed from multiple angles. Sometimes, math tutors, as part of the tutoring system, are framed as the contributors of shadow education and the parasite of the national educational system. We claim that some math tutors are financially vulnerable. Our paper serves to bring new nuances into the complexity of being math tutors during the Covid-19 pandemic time. In doing so, we employed the qualitative study method by elaboratively interviewing five Indonesian mathematics tutors during September 2021. Specifically, this article focused on three aspects related to math tutoring: challenges, adaptations, and success. By listening to their stories, we gained some insights. First, tutors who were struggling the most are the ones who come from a poor background and who work for middle-low-income students. Second, the cost of adapting to the new work environment as math tutors need to upgrade their devices is one of the contributing factors in transitioning from offline tutoring to online tutoring. Third, those who thrived are the ones who are familiar with online tutoring, already have decent devices which are sufficient for heavy online multi-tasking work, and are in the circle of upper-middle-income families. In retrospect, this research not only sheds light on social issues in our educational system but also raised some key practical issues of teaching mathematics online which may affect tutors with various backgrounds differently. All in all, our research is part of our endeavor to fight for math tutors’ welfare.
