Published: September 2024

There are differences of opinion arising from the results of research on the use of WhatsApp in ELT. The results revealed that the use of WhatsApp software contributed positively to the development of English writing proficiency, and the other results considered that the use of WhatsApp has many weaknesses and difficulties in writing and other language instructions. This controversy allowed the researcher to conduct research aimed at finding out whether there was a correlation between the use of WhatsApp as a tool in writing activities and EFL student writing performance and to find out how close the relationship between the two variables is. The statistical correlation from Pearson Product Moment revealed that the correlation of the independent variable (X) with the dependent variable (Y) showed a sig. value of 0.000 < 0.05, and the correlation rate was very strong with a correlation coefficient (r = 0.832), along with the hypothesis tested showing Ho: ?1 ? 0. This study shows a very strong correlation between the use of WhatsApp as a tool in English writing activities and writing performance. WhatsApp interventions into ELT in the form of group WhatsApp and individual WhatsApp’s text message interactions have contributed to EFL students’ writing skills as the correlation of two variables goes parallel. The more students do the writing activity through WhatsApp, the higher the writing achievement they acquire.

Study objective: Pain arising from femur fractures is of severe nature. Surgery for xation of femoral
fractures may be done under spinal anesthesia. We conducted this study to compare the analgesic
efcacy of fascia iliaca compartment block (FICB) and intravenous fentanyl (IVF) before positioning for spinal anesthesia.
Design: Randomized controlled trial. Setting: Operating room. Patients and interventions: Sixty patients aged 25 to 75 years,
with American Society of Anesthesiologists status I to II, undergoing surgery for femur fracture were chosen for the study and
randomized into 2 groups. Patients in group FICB received the block with 30 mL of 0.25% ropivacaine 15 minutes before the
subarachnoid block. Patients in group IVF received intravenous fentanyl at 1 µg/kg body. Spinal: All the patients received
spinal anaesthesia with 0.3mg/kg of 0.5% hyperbaric bupivacaine. Measurements: Preprocedural and postprocedural
parameters such as visual analog scale (VAS) scores, sitting angle, quality of positioning, and time to perform the spinal were
recorded. Main results: Preprocedural VAS scores were similar in both groups. The "VAS after" was 24.72 ± 15.70 mm in group
FICB vs 61.22 ± 18.18 mm in group IVF (P = .01). The drop in VAS scores was signicantly more in the FICB group. Postoperative
analgesic requirement was lesser in group FICB. This work is attributed to the Department of Anesthesiology
ECTOPIC ERUPTION OF MAXILLARY FIRST PERMANENT MOLARS: A REVIEW
Authors: Jain Anushka , Thakur Seema , Singhal Parul
Published: September 2024

Ectopic eruption of permanent molars arises when a permanent tooth diverges from its expected eruption
trajectory. The etiology of this condition is multifactorial, incorporating both systemic and local
inuences. The severity of the impaction of the rst permanent molar serves as a critical predictor of irreversible effects. While
self-correction predominantly occurs between the ages of 7 and 8, intervention becomes necessary if this does not happen. Early
intervention is paramount to avert potential occlusal complications, and the choice of treatment is inuenced by factors such as
mesial tilting, root resorption, and the status of the second primary molar. Primary treatment approaches include interproximal
wedging and distal tipping, with the possible use of xed or removable appliances. Delayed treatment is inadvisable,
underscoring the necessity of early diagnosis. This review provides a thorough examination of ectopic permanent molars,
emphasizing the critical need for early detection and intervention, and calls for further research into the determinants of
irreversible outcomes.

Published: September 2024

This study assessed the effectiveness of ultrasound (US) and magnetic resonance imaging (MRI) in
diagnosing shoulder pathologies in 70 patients presenting with shoulder pain. MRI emerged as the more
sensitive and specic modality overall, particularly for partial-thickness rotator cuff tears and tendinopathy, with sensitivities of
81.82% and 100%, respectively, compared to 66.66% and 64.29% for US. Both imaging techniques showed similar sensitivities
for detecting full-thickness rotator cuff tears (91.67% for US and 92.31% for MRI). MRI also provided superior detail for identifying
labral tears and uid accumulation. Although MRI offers enhanced diagnostic accuracy, its higher cost and limited availability
are notable drawbacks. Conversely, US remains a valuable screening tool due to its lower cost, quicker examination, and realtime imaging capabilities, making it especially useful when MRI is not accessible or feasible. Thus, while MRI is preferred for
denitive diagnoses, US serves as an effective, cost-efcient rst-line tool for assessing shoulder pathologies.

Authors: A Shah Keval , Moulick Nivedita , Desai Utsavi
Published: September 2024

Background: Cardiovascular disease (CVD) is the leading cause of death and disability worldwide.The risk factors for
myocardial infarction are divided into non-modifiable (irreversible) and modifiable (reversible). Glycosylated
hemoglobin (HbA1c) is an important test that should be done in non-diabetic hyperglycemic patients and diabetic
patients who have not been tested recently.Hence the current study was undertaken to study the effects of plasma blood
glucose levels on admission and glycosylated hemoglobin (HbA1c) on the complications and outcome of acute
myocardial infarction. Aims and Objectives: Study of plasma glucose levels and glycosylated hemoglobin (HbA1c) on
admission as a prognostic indicator of Acute Myocardial Infarction. Materials & Methods: This prospective crosssectional study examined the prognostic value of admission plasma glucose levels and glycosylated hemoglobin
(HbA1c) in acute myocardial infarction (MI). Conducted over one year at D.Y. Patil Hospital, the study included 100
patients (65 male,35 female) admitted with acute MI.Patients were categorized into STEMI and NSTEMI groups based on
ECG findings, and further divided into diabetic (HbA1c>7%) and non-diabetic (HbA1c<7%) groups. The study
assessed glucose levels, HbA1c levels, and their correlation with complications and outcomes in acute MI patients.
Results: We found higher mean glucose (172.4 mg/dL vs 135.2 mg/dL) and HbA1c levels (8.5% vs 6.2%) in diabetic
patients compared to non-diabetics. Diabetic patients experienced a higher incidence of complications, including
arrhythmias,cardiac failure,and cardiogenic shock.Notably,all six mortalities within 72 hours of admission occurred in
diabetic patients, indicating worse outcomes and higher mortality rates in this group. The study found a significant
correlation between glycemic profile and complications/outcomes in diabetics versus non-diabetics. These findings
underscore the importance of blood glucose as a prognostic marker in acute MI.Additionally; the study highlights the
utility of HbA1c in differentiating between stress hyperglycemia and diabetes in acute MI patients. Conclusion: In
conclusion, this research emphasizes the value of assessing plasma glucose and HbA1c levels on admission for
predicting complications and outcomes in acute MI patients, particularly in distinguishing between diabetic and nondiabetic individuals.

Published: September 2024

Anemia is a major public health concern and has a significant impact on women and children worldwide. This condition is caused by a lack of sufficient Red Blood Cells (RBCs). Traditionally, anemia diagnosis has relied on invasive techniques that require blood samples, leading to pain and discomfort. This study explores deep learning techniques for automating and enhancing anemia detection accuracy using the Blood Cell Count and Detection (BCCD) dataset. We employ the VGG16 convolutional neural network architecture augmented with the Convolutional Block Attention Module (CBAM) to boost feature representation and performance. The BCCD dataset, consisting of 364 images with 4888 labeled blood cells, was used for training and evaluation. Our enhanced VGG16 model achieved accuracy for RBCs, WBCs, and platelets with values of 0.84, 0.93, and 0.92, respectively, effectively identifying various blood cell types and detecting anemia. Precision-recall analysis and confusion matrix metrics confirmed the robustness of the model, with high precision and recall rates and minimal false positives and negatives. These results suggest that advanced deep learning models with attention mechanisms, such as CBAM, can significantly improve medical diagnostics by providing reliable, efficient, and accurate early disease detection tools. Future development will be directed towards fine-tuning and validating the proposed model on other medical imaging datasets for clinical applications.

Published: September 2024

Banana cultivation is one of the important commercial crops in states such as Espírito Santos, which unfortunately suffers from problems related to fungi, such as Colletotrichum musae. We use synthetic fungicides that are problematic and end up creating resistance over time, in addition to being toxic to the environment. One of the options to overcome this problem is the chemistry of natural products based on essential oils, which has shown excellent results in several studies in the literature. Therefore, this work aimed to verify the activity of essential oils of rosemary (Rosmarinus officinalis), Eucalyptus (Eucalyptus globulus), basil (Ocimum basilicum) and ginger (Zingiber officinale) in concentrations obtained from commercial sources. The oils were characterized by gas chromatography with flame ionization detector (GC-DIC) mass spectrometry (GMS), while fungicide tests were conducted by diluting the plate containing the fungus Colletotrichum musa. In the fungicide test, only two oils showed activity: eucalyptus oil and ginger oil. These two oils achieved inhibition rates like those of the commercial fungicideTecto©, with inhibition rates greater than 70% at tested concentrations of 0:1.50:2.50:2, 55:2,60:2, 65:3.00 μL/ml, The fungicidal activity of these two oils may be linked to their chemical composition. In eucalyptus oil the main component is eucalyptus with 88.64%, while in ginger oil α-zingibene is the main component with 43.29% of the surface area. In rosemary oil, the main compound is eucalyptus with 48.74% and in basil oil, chavicol is the main compound with 76.00%.

The constant advance in technology, instrumentation, and the increase in data generation capacity has resulted in a new challenge for chemists: how to deal with complex, extensive, and multidimensional data sets. In this scenario, chemometrics emerged as a branch of chemistry specialized in the application of statistical and mathematical techniques for the analysis of multivariate analytical data, resulting in more precise and reliable scientific conclusions. As it is a relatively new area, there is still a lack of educational resources on the subject, and chemometric approaches are mostly confined to postgraduate courses. Therefore, this article provides a tutorial that can be used in various academic instances, with a focus on undergraduate education, to teach partial least squares regression (PLS). PLS is considered one of the most essential and common methods in chemometrics, and stands out for its ability to efficiently handle complex and highly correlated data sets, which is particularly important in regression analysis when there is significant multicollinearity among independent variables. In addition, PLS is known for its ease of use, making it a valuable tool for professionals seeking an effective approach to complex statistical modeling. We detail all the steps to create a complete PLS model, from installing the free GNU Octave software to producing the final figures. We also provide all the algorithms developed for data reading and processing. Finally, we interpret the obtained results so that the discussions and conclusions are easily understood by everyone.

Published: September 2024

The present study investigated the production of biodiesel by transesterification of residual frying oil (ORF), highlighting the use of heterogeneous catalysts, specifically CaO impregnated in rice husk ash (CCA). The ORF was characterized by the presence of hydrolytic and oxidative rancidity, evidenced by the acid value and the Kreis test, respectively, indicating its suitability for the production of biodiesel, but unsuitable for direct consumption. The catalyst support was obtained through acid leaching followed by calcination in a muffle furnace for 3h at 500°C. The esters obtained during the transesterification reaction were quantified by 1H-NMR. From the parameters used in the reactions, a maximum yield of 1.57% was obtained for the ORF. The experiments indicated that temperature showed little impact on conversion, while reducing the amount of catalyst moderately increased conversion, making production economically advantageous. Although the catalyst has potential, future optimizations are needed to improve conversion to biodiesel, thus contributing to more efficient and sustainable methods in the biofuels industry.

Glioblastoma multiforme (GBM) is the most common primary brain tumor, characterized by poor overall survival and near-universal recurrence due to rapid proliferation and treatment resistance. Inflammatory markers (i.e., cytokines and acute phase reactants [APRs]) have been studied in serum as potential biomarkers in GBM. However, the lack of serum data collected at multiple time points, particularly during treatment interventions, has limited the translation of these findings into clinical applications for monitoring treatment response. In this study, we analyzed a panel of 29 cultivated serum inflammatory markers employing serum from 109 individuals with pathology-proven GBM, collected both pre- and post-chemoradiation therapy (CRT). The goal was to determine the feasibility of measuring these serum markers in patient samples and to understand the effects of CRT on inflammatory biomarkers and signaling pathways. Among the proteins studied, albumin, C-reactive protein (CRP), glial fibrillary protein (GFAP), kininogen, interleukin (IL)-13, IL-1b, IL-10, Parkinson’s disease-1, vascular cell adhesion molecule 1 (VCAM-1), and tumor necrosis factor-alpha (TNF-α) were the most significantly altered following CRT. Of these, albumin, CRP, GFAP, IL-6, VCAM-1, and TNF-α emerged as the most relevant and promising serum biomarkers. Interaction analyses of baseline and post-CRT data identified IL-6 as a potential driver of signal alteration linked to APRs pathways and suggested its role as a mediator of tumor microenvironment reprogramming in conjunction with TNF-α and VCAM-1. The data revealed a balancing act of pro-apoptotic, anti-proliferative, and pro-viability pathways, with significant impacts on the signal transducer and activator of transcription 3 and nuclear factor kappa B pathways. Overall, the altered signature of the examined serum biomarkers suggests a decrease in the inflammatory response following GBM treatment. These findings underscore the need for further research, incorporating clinical outcomes and validation in larger datasets, to confirm the clinical applicability of these biomarkers.

Викладено та проаналізовано цілі сталого розвитку (ЦСР) для України крізь призму умов війни. Досліджено вихідні позиції забезпечення ЦСР в Україні на момент початку війни й порівняно з цими позиціями проаналізовано перетворення у концептуальному сприйнятті їх досягнення на сьогодні.
Особливу увагу сконцентровано на соціальному, економічному, екологічному та управлінському векторах досягнення цілей сталого розвитку. Визначено, що руйнівні наслідки від військових дій виявилися критичними для майже всіх внутрішньоекономічних показників, що зумовило за принципом доміно реакцію дисбалансу усіх макроекономічних показників не тільки європейського регіону, але й у глобальному масштабі. Обґрунтовано, що найбільшого деструктивного впливу на світовому рівні зазнали глобальна продовольча безпека; світова енергетична безпека, прогрес у поступовому переході на чисту енергію; глобальна екосистема, що стосується збереження водних ресурсів земельних ресурсів; стан багатосторонності міжнародних відносин та співробітництва у досягненні цілей сталого розвитку. На регіональному та національному рівнях є проблеми у досягненні всіх цілей сталого розвитку, найуразливішими виявилися: подолання голоду, подолання бідності, якісна освіта, міцне здоров'я та благополуччя, доступ до енергоресурсів тощо.
Концептуальних змін зазнало сприйняття таких основних ідей сталого розвитку, як: інституційна стійкість самого підходу як парадигми суспільного зростання ХХІ ст.; принцип добровільності і добросовісності виконання зобов'язань; розширення розуміння необхідності розбудови зеленої енергетики не тільки як інструменту застереження змін клімату, а й частини системи безпеки світу; необхідність зміни принципів і механізмів партнерства заради досягнення цілей сталого розвитку.

Розглянуто проблему об'єктивності та якості управлінського контролю, який спрямований на підвищення ефективності, прозорості та обґрунтованості управлінських рішень у сфері господарської діяльності установи. Проаналізовано найбільш суб'єктивну складову публічних закупівель - кваліфікаційні критерії. На підставі зібраної інформації визначено слабкі позиції, поширені помилки та ризики у застосуванні кваліфікаційних критеріїв процедур закупівлі. Аргументовано, як цей чинник, за умов недостатнього внутрішнього контролю, може негативно впливати на загальний результат діяльності установи. Визначено, що систематичне застосування методик оцінювання ризиків у публічних закупівлях дає змогу істотно зменшити шанс отримати затяжні, неуспішні закупівлі.
Наголошено, що проблема контролю в державних закупівлях є актуальною від початку впровадження системи державних закупівель. Акцентовано, що функції та завдання контролю змінюються з розвитком галузі і появою нових викликів: відсутність у замовників та учасників практичного досвіду на початкових етапах роботи системи Prozorro і необхідність його набувати в процесі роботи з державними закупівлями, організація документообігу, потоковий процес у державних закупівлях, технічна складова електронної системи закупівель.
Визначено, що система публічних закупівель в Україні пройшла певну природну трансформацію у період становлення, розвитку, змін законодавства, переходу від організації та проведення закупівель тендерним комітетом до персональної відповідальності за порушення законодавства у сфері публічних закупівель фактично двох осіб в установі - уповноваженої особи з публічних закупівель та безпосередньо керівника установи, чия відповідальність зумовлена специфікою повноважень у сфері організації внутрішнього контролю в установі.
Екологічне управління в системі реалізації цілей сталого розвитку

Published: September 2024

Екологічне управління в системі реалізації цілей сталого (стійкого) розвитку розглянуто як концептуальний фокус науки публічного управління в сучасній та стратегічній перспективі. Стійкий розвиток аргументовано як найбільш конструктивний підхід, актуальний практично для всіх сфер суспільства і управління не тільки для більшості європейських країн, але й в глобальному масштабі. Охарактеризовано динаміку формування конструктивних теоретичних концептів сталого розвитку ІІ пол. ХХ ст. та інноваційних моделей екологічного управління поч. ХХІ ст. у контексті завдань публічного управління. Відзначено цілі та основні елементи екосистемного підходу, що взаємодіють у реалізації цілей стійкого розвитку. Узагальнено аргументацію екологічної стійкості як визначальної характеристики екосистемного підходу. Визначено критерії оцінювання її результативності. Послідовно розвинено думку про безпосередній зв'язок екологічного добробуту і спроможності політичних інститутів утримувати екологічну рівновагу. При цьому відзначено здатність інститутів у демократичних державах захищати екосистеми краще, ніж в авторитарних. Актуалізовано нагальну потребу вирішувати проблеми ефективності альтернативних моделей економіки, відображені в поточних дебатах з питань "зеленої" економіки, робочих місць, розумного зростання, муніципальної стійкості та змін у розумінні місії влади, суспільного призначення управлінської діяльності та ролі громадянського суспільства і конкретної людини. Доведено органічний зв'язок вирішення проблем екології та забезпечення економічної ефективності, соціальної справедливості, політичної стабільності, національної безпеки, здоров'я населення та якості життя. У тематику подальших досліджень екологічного управління в системі реалізації цілей стійкого розвитку доцільно включити, зокрема, розроблення екосистемного підходу як набору керівних принципів реалізації державної політики у сфері екології в Україні.
Глобальне управління у сфері кібербезпеки в контексті сучасних викликів та загроз Україні

Кібербезпеку розглянуто як основний фактор національної та міжнародної безпеки ХХІ століття. Аргументовано, що численні ініціативи у сфері правового забезпечення кібербезпеки охоплюють тільки невелику частину міжнародної правової системи, зокрема, щодо захисту критичної інфраструктури, захисту приватних даних у мережі, ведення війни із застосуванням кібертехнологій. Наголошено, що кібербезпека охоплює вже не тільки інформацію як об'єкт захисту, не тільки технічні засоби, які визначають можливості функціонування інформації, а, водночас, захист способів функціонування нової сутності – кіберпростору. Проаналізовано політико-правові документи, що визначають суть та спрямування національної політики кібербезпеки на прикладі окремих країн та визначено їх роль у міжнародно-правовому просторі. Особливу увагу приділено дослідженню агресивних стратегій Росії та Китаю у створенні критичних кіберзагроз. Розкрито особливі виклики, з якими стикається Україна під час активізації кібервійни з боку Російської Федерації як складника повномасштабного вторгнення. Аргументовано недоліки концептуального розуміння кібербезпеки в Україні, Європейському Союзі та США. Наголошено, що враховуючи те, що кібербезпека є глобальною проблемою, до неї потрібен глобальний підхід. Доведено необхідність міжнародного співробітництва, зокрема, на основі потрійної спіралі та механізмів кооперенції. Конкурентне суперництво та закритість у цій сфері, орієнтація виключно на національно-державні інтереси приведуть до клаптевого характеру глобального управління кібербезпекою, що істотно знизить його потенціал.

Authors: Oteng Bernice
Published: September 2024

Introduction: In Ghana, the National Council for Curriculum and Assessment of the Ministry of Education considers assessment as an integral part of the standards-based curriculum. Teachers are therefore required to look at what they do as regards classroom assessment practices. This discourse reflects the classroom assessment practices of Junior High School (JHS) Social Studies Teachers in the Ga East Municipality. The paper relies on Title’s (1994) Theory and Mohamad’s (2009) framework for classroom assessment practices. A survey was conducted on 60 Social Studies teachers sampled via the census sampling technique. The Teachers Practice of Classroom Assessment Questionnaire (TPCAQ,?=0.81) for data collection. Descriptive statistics (frequency count, percentage, mean), measures of dispersion and variability (standard deviation), and t-tests were used to analyse the data. The study revealed that classroom assessment practices of JHS Social Studies teachers were satisfactory, mean ( ?2.95), except for students’ involvement in assessment practices ( = 2.26). The major practices of the teachers were: feedback practices ( = 3.28), revision of assessment practices (  = 3.20), and communication of assessment results to students ( = 2.98). Female teachers performed better than their male counterparts on all the classroom assessment practice constructs (p=0.000). The study concludes that classroom assessment practices involving feedback practices, revision of assessment, communicating assessment results, and students’ involvement in assessment are critical to Social Studies education in Ghana. Therefore, the Ga East Municipal Directorate of Education should periodically train Social Studies teachers on best practices in classroom assessment to improve their assessment practices.
