Background and Study Aim. The study intends to estimate the theoretical and applied perspectives of the Kinesiology discipline in the field of Sport and Physical Education science.

Material and Methods. A total number of 127 subjects (students of the Physical Education and Sport Department in the University of Pitești) participated in this research. There are 59 students in Physical Education and Sport (PES), 37 in Sport and Motor Performance (SMP) and 31 in Physical Education and Sport Conversion (PESC). The research was conducted during COVID-19 pandemic, in the academic year 2021-2022. The teaching and evaluation activity in the Kinesiology discipline was carried out online by means of Zoom program. The monitoring of the teaching activity was done with the help of the university e-learning platform. The opinions of the subjects on the discipline taught and the assessment of the teaching staff by the students were analyzed using Google Forms questionnaire. The fundamental basic knowledge in Kinesiology was evaluated using the following indicators: S1 (periodically evaluated activities) = A1 (40%) +A2 (20%), final evaluation (FE) – examination (40%), S2 – sum of the fractions of grade obtained at the periodic evaluations and those from the final verification.

Results. The analysis of the subjects’ opinions regarding the topic of the discipline taught reveals 5% moderate opinions, 16% - good and 79% very good ones. The evaluation of the basic fundamental knowledge in Kinesiology highlights the following values of the indicators: A1 (40%) – an average of 8.05 points between groups (p<0.01); A2 (20%) - an average of 7.95 points (p>0.05); S1 – an average of 4.81 points (p<0.05). The final evaluation (40%) in the exam shows an average of 3.36 points (p<0.01); S2 has 8.17 points (p<0.01); the final grade between groups has an average of 8.29 points, with differences of rounding in student’s favor (p<0.05). The analysis of students’ opinions concerning the teaching activity in Kinesiology discipline shows that 76% rate it as excellent, 14% - very good, 6.7% - good, 1.9% - satisfactory and 1.4% unsatisfactory (extracurricular activity).

Conclusions. There were shown the subjects’ opinions on the Kinesiology discipline topics and the weight of meeting the minimum and maximum performance standards. The preferred or practiced sports chosen in the researched study programs were presented. The results of the evaluation of the basic fundamental knowledge highlight the value of the averages between groups for the evaluated indicators. These results also reveal the opinions of the students about the didactic activity carried out by the professor in the discipline studied.

Authors: Bui Thi Thu Hoai , Tran Thi Thom , Nguyen Dinh Kien
Published: December 2022

In this work, geometrically nonlinear behavior of sandwich composite beams reinforced by carbon nanotubes is studied, taking into account the influence of agglomeration of the carbon nanotubes (CNTs). The core of the sandwich beams is homogeneous while the two face sheets are made of CNT reinforced composite with the effective material properties being estimated by the Eshelby-Mori-Tanaka approach. A first-order shear deformable nonlinear beam element is formulated in the context of the total Lagrange formulation and used to construct the discretized nonlinear equilibrium equation. The Newton-Raphson based iterative procedure is used in conjunction with the arc-length method to trace the equilibrium paths of the beams. Detail parametric studies are carried out to illustrate the influence of the CNTs agglomeration, the amount of CNT volume fraction as well as the thicknesses of face sheets on the nonlinear behavior of the structure.
A new analytical approach of nonlinear thermal buckling of FG-GPLRC circular plates and shallow spherical caps using the FSDT and Galerkin method
Authors: Tu Bui Tien , Ly Le Ngoc , Phuong Nguyen Thi
Published: December 2022

A new analytical approach for nonlinear thermal buckling of Functionally Graded Graphene Platelet Reinforced Composite (FG-GPLRC) circular plates and shallow spherical caps using the first-order shear deformation theory (FSDT) is presented in this paper. The circular plates and shallow spherical caps are assumed to be subjected to uniformly distributed thermal loads. By applying the Galerkin method, the relations between thermal load–deflection are achieved to determine the postbuckling behavior and critical buckling loads of the considered structures. Special effects on the nonlinear thermal behavior of circular plates and shallow spherical caps with five different material distribution laws, different Graphene platelet (GPL) mass fractions, and geometrical dimensions are explored and discussed in numerical examples.

Published: December 2022

Bioinspired structures are remarkable porous structures with great strength-to-weight ratios. Hence, they have been applied in various fields including biomedical, transportation, and aerospace materials, etc. Recent studies have shown the significant impact of the plastic 3D printed triply periodic minimal surfaces (TPMS) structure on the cement beam including increasing the peak load, reducing the deflection, and improving the ductility. In this study, a machine learning (ML) surrogate model has been conducted to predict the beam behavior under static bending load. At first, various combinations of plastic volume fractions and numbers of core layers have been adopted to reinforce the constituent beam. The finite element method (FEM) was implemented to investigate the influences of these reinforcement strategies. Next, the above data were employed to create the ML model. A three-process assessment was proposed to achieve the most suitable model for the present problem, these processes were the model hyperparameter tuning, the performance assessment, and the handling overfitting with deep learning (DL) techniques. Consequently, both beam peak loads and maximum deflections were proportional to the volume fraction. The increment in TPMS layers could lead to the enhancement in both traits but with a nonlinear relationship. Furthermore, each trait may be a ceiling value that could not be exceeded with a specific volume fraction despite any number of layers. This conclusion was indicated by the surrogate model predictions. The final model in this study could deal with noisy data from FEM and with the support of a new early stopping condition, excellent performance could be found on both train and test data. The maximum deviations of 2.5% and 3.5% for peak loads and maximum midpoint displacements, respectively, have verified the robustness of the present surrogate model.

Published: December 2022

The goal of the current paper is to characterize the $\ast$-$k$-Ricci-Yamabe soliton within the framework on Kenmotsu manifolds. Here, we have shown the nature of the soliton and found the scalar curvature when the manifold admits the $\ast$-$k$-Ricci-Yamabe soliton on the Kenmotsu manifold. Next, we have evolved the characterization of the vector field when the manifold satisfies the $\ast$-$k$-Ricci-Yamabe solitons. Also we have embellished some applications of vector field as torse-forming in terms of $\ast$-$k$-Ricci-Yamabe soliton on Kenmotsu manifold. Then, we studied the gradient $\ast$-$k$-Ricci-Yamabe soliton to yield the nature of the Riemannian curvature tensor. We have developed an example of a $\ast$-$k$-Ricci-Yamabe soliton on a 5-dimensional Kenmotsu manifold to prove our findings.

Authors: CHEN Boling , TAM Vo Minh
Published: December 2022

In the present paper, we are concerned with investigating error bounds for history-dependent variational inequalities controlled by the difference gap (for brevity, $\mathcal{D}$-gap) functions. First, we recall a class of elliptic variational inequalities involving the history-dependent operators (for brevity, HDVI). Then, we introduce a new concept of gap functions to the HDVI and propose the regularized gap function for the HDVI via the optimality condition for the concerning minimization problem. Consequently, the $\mathcal{D}$-gap function for the HDVI depends on these regularized gap functions is established. Finally, error bounds for the HDVI controlled by the regularized gap function and the $\mathcal{D}$-gap function are derived under suitable conditions.

A historiografia antiga e a consciência do método da investigação histórica
Authors: Da Silva Dyel , Santos Dominique
Published: December 2022

Durante a Modernidade, a história se tornou disciplinarizada e ganhou o status científico que lhe atribuímos hoje. Nesse período, surgiram regras e condições para que um trabalho fosse classificado como historiográfico, sendo aplicadas a textos de diferentes lugares e tempos. O problema interpretativo de tal posicionamento é abordado neste artigo, a partir da história dos conceitos (Begriffsgeschichte), por meio de uma análise do “Livro XII” de Políbio de Megalópolis, uma fonte histórica privilegiada para compreender como se fazia história na Antiguidade. Após nos determos brevemente sobre o gênero historiográfico polibiano e os domínios de sua epistemologia, corroboramos a tese de que a moderna classificação da história da historiografia é excludente e contradiz o próprio historicismo ao aplicar critérios modernos a trabalhos não pertencentes a essa delimitação espaço-temporal, praticando uma espécie de anacronismo ao julgar a historiografia antiga a partir da ótica da historiografia moderna.

Published: December 2022

Günümüzde öğretmenler kişisel, mesleki ve kültürel olarak kendilerini sürekli geliştirmek durumundadırlar. Bu gelişimi sağlamak için hizmet öncesi dönemden itibaren yaşam boyu öğrenmeyi hedeflemeleri gerekmektedir. Buradan hareketle bu araştırmanın amacı, öğretmen adaylarının yaşam boyu öğrenme eğilimlerini incelemek ve bu eğilimleri cinsiyet, sınıf düzeyi, lisansüstü eğitim alma isteği ve bölüm tercih sebebi değişkenleri açısından karşılaştırmaktır. Bu araştırma betimsel araştırma modelindedir. Araştırmada tarama araştırması yöntemi kullanılmıştır. Araştırma uygun örnekleme yöntemine göre belirlenen 357 öğretmen adayı ile gerçekleştirilmiştir. Veriler, Coşkun Diker (2009) tarafından geliştirilen “Yaşam Boyu Öğrenme Eğilimleri Ölçeği (HBÖÖ)” ile toplanmıştır. Araştırma kapsamında öğretmen adaylarının yaşam boyu öğrenme eğilimlerini belirlemek için betimsel istatistikler hesaplanmıştır. Değişkenlere göre karşılaştırmalarda ise verilerin normalliği sağlanamadığı için parametrik olmayan testlerden Mann-Whitney U ve Kruskal-Wallis testi kullanılmıştır. Araştırmadan elde edilen bulgular ışığında öğretmen adaylarının yaşam boyu öğrenme eğilimlerinin düşük olduğu söylenebilir. Erkek öğretmen adaylarının yaşam boyu öğrenme eğilimlerinin kadın öğretmen adaylarına göre daha yüksek olduğu belirlenmiştir. Birinci sınıf öğretmen adaylarının sebat puanın ikinci ve dördüncü sınıf öğretmen adaylarına göre daha düşük olduğu belirlenmiştir. Öğretmen adaylarının yaşam boyu öğrenme eğilimleri lisansüstü eğitim almak istemeyenler lehine anlamlı bir farklılık göstermektedir. Son olarak bölümü “istihdam ve çalışma koşullarını” dikkate alarak seçen öğretmen adaylarının yaşam boyu öğrenme eğilimleri “diğer” nedenlerle seçenlere göre daha yüksek bulunmuştur. Araştırmadan elde edilen bulgular ışığında, eğitim fakültelerinde dersler ve ders dışı eğitim faaliyetleri ile öğretmen adaylarının yaşam boyu öğrenme eğilimlerinin geliştirilmesi yönünde öneriler sunulmuştur.

Published: December 2022

This qualitative research study investigated the influence of YouTubers on adolescents’ identity construction by exploring interactions between YouTubers and adolescents. Towards this goal, this study intended to examine YouTubers’ role in adolescents’ lives in terms of mindset and daily practices. In this interpretative phenomenological study, the analyses of the data collected from 10 adolescents through semi-structured interviews revealed that YouTubers guided adolescents to become integrated into the society by noticing the similar aspects of their identities such as feelings, thoughts, and beliefs. Furthermore, YouTubers have been found to assist adolescents to discover their individuality through their videos and comments of other viewers on these videos. Also, it has been observed that the exploration option and range of social interactions extended thanks to the YouTubers. However, adolescents sometimes overly identified themselves with the YouTubers, imitated them and implemented the YouTubers’ recommendations without questioning.

Integration of Virtual Reality (VR) Technology into Vocabulary Teaching in Primary School English Lessons
Authors: UYGUN Emre , GİRGİN Derya
Published: December 2022

Language consists of words, so it is important to increase the level of vocabulary in any foreign language learning to a certain extent in order to be able to communicate in that language. As for VR, it is seen that this technology is a new research field in education, the use of which in language teaching is closely related to the principle of proximity to life, one of teaching principles. While learning a foreign language, learners should experience situational learning experiences, recognize real-life contexts, and be able to use the language communicatively in these environments, which is a difficult goal to be attained by 2nd-grade primary school students who have not yet reached full proficiency in their native language but started learning a foreign one. In this direction, this study, a pre-test – post-test research with the control group, examined VR’s effect on vocabulary levels and student engagement. The study was conducted in the English lessons of 2nd-grade students from six of the state primary schools in the central district of Çanakkale, Turkey. The results indicated that instruction with VR did not show any significant difference in vocabulary levels compared to current teaching method but encouraged more student engagement in the classroom. Although more extensive research into the topic is essential, it is hoped that the study will shed light on future research on the use of VR technology, which still has leeway to progress and may form the basis of future education in the coming years.

Para comprender uno de los pilares que sustentan una cultura africana compleja con sus hábitos, prácticas y vivencias, reelaborada en este país llamado Brasil a través de los afrodescendientes, es importante apropiarse de este conocimiento. A través del análisis de investigaciones realizadas por varios autores, se pretende estructurar ese pensamiento milenario que mucho ha contribuido y contribuye a la construcción de la nación brasileña. Y luego, desde ese conocimiento, llevar al margen hechos poco conocidos y entendidos que quedaron sumergidos por la continua exclusión, descalificación y racismo contra el grupo negro. Tenemos como local la ciudad de São Paulo que fue consagrada como centro industrial, pero que, debido a la mentalidad excluyente, borró las referencias negras de su historia. En sus inicios, São Paulo se caracterizó por una población negra y una fuerza cultural bantú. Marcador que se puede aprehender mirando la toponimia de la ciudad. Este artículo es parte de un estudio que involucra la recuperación de la memoria social y cultural y se enfoca en el estudio de uno de los candomblé terreiros que son símbolos de la ciudad y que es poco conocido en la literatura sobre la historia de la ciudad y la importancia de haberse convertido en un sitio patrimonial, material e inmaterial, O Axé Ilê Obá siendo de la cultura bantú su estructura, entre otros, está enfocada a la naturaleza y cómo nos da dimensiones en la forma de ser y estar en el mundo a través de sus representaciones y interfiriendo con el paisaje que tenemos en la ciudad.

Authors: Gritsenko V.V. , Reznik A.D. , Konstantinov V.V. , Guzhva I.V. , Marinova T.Y. , Isralowitz R.
Published: December 2022

The article presents the analysis results of stress resistance and basic beliefs as psychological resources for coping with fear of COVID-19 and negative psychological and emotional states on the sample of Russian (N=2310) and Kazakh (N=500) students (71.2% — women, average age 19.7). A higher level of stress resistance and basic belief expression in Benevolence of the World Around and Perceiving the World as Meaningful and Social Justice among Kazakh students in comparison with Russian ones is revealed, which is determined by the peculiarities formed in the conditions of the nomadic lifestyle of the Kazakh culture, based on the principles of mutual support and mutual assistance, trust and openness. It is shown that, regardless of the country and gender, high level of stress resistance and expression of basic beliefs are accompanied by lower indicators of fear of COVID-19 and the absence of negative psychological and emotional states associated with it, which suggests the universality of these psychological resources as a buffer that mitigates the traumatic effect of the pandemic situation.

Authors: Arfaoui Siham , MEZRIOUI Abdellatif , BELMEKKI Abdelhamid
Published: December 2022

There is no doubt that privacy by design PbD has become a structuring paradigm for personal data protection. Certainly this paradigm has been in use since 1995; however the GDRP "The General Data Protection Regulation", by considering PbD in 2018 as a legal obligation, it testifies the PbD seven principles relevance. Companies are therefore called to put in place technical and organizational measures to integrate PbD into companies. Hence the need for a methodology to provide an exhaustive approach adapted to this implementation. Given the focus of the literature on the implementation of methodologies dedicated to the embodiment of PbD only in software systems, this article aims to propose an ISPM methodology "Information System Privacy Methodology" which focuses on the implementation of PbD in the enterprises architecture, specifically in information systems taking into account all the technical and organizational aspects which must be adopted for the said goal success.

Published: December 2022

The Internet of Things (IOT) is a revolution in the technology world, and this field is continuously evolving. It has made life easier for people by providing consumers with more efficient and effective resources in faster and more convenient ways. The Internet of Things is one of the most exciting fields for the future by 2030. 90% of the planet will be connected and all devices in homes and businesses around us will be connected to the Internet making it more vulnerable to violations of privacy and protection. Due to the complexity of its environment, security and privacy are the most critical issues relevant to IoT. Without the reliable security of the devices, they will lose their importance and efficiency. Moreover, the security violation will outweigh any of its benefits. In this paper, an overview of various layered IoT architectures, a review of common security attacks from the perspective of the layer, and the best techniques against these attacks are provided. Moreover, an enhanced layered IoT architecture is proposed, which will be protected against several security attacks.

Published: December 2022

In this paper, we present Modify Deep Hiding Extraction Algorithm (MDHEA) that is a steganography algorithm with Multi-Level Steganography (MLS) and color image segmentation. Through experimental results, MDHEA shows improvement in the results of previous works by securing encrypted secret data against attacks. We use segmentation to choose the appropriate segment, pass it on the cover image, calculate the value of the change at the pixel of the segment and select the best segment and its location in the cover image based on the least effect. MDHEA applies multi-level steganography to hide the confidential data in color images to ensure the integrity of the hidden data and obtain the largest volume of hidden data without distorting the image of the stego image. To reduce distortion in the cover image due to hiding a large amount of secret data and obtaining a high-quality stego image after hiding the secret data, we implement the Blue Smoothing Algorithm (BSA) to achieve smoothing the largest possible number of pixels in the image.

Published: December 2022

Currently, vehicular communications have become a reality used by various applications, especially applications that broadcast video in real time. However, the video quality received is penalized by the poor characteristics of the transmission channel (availability, non-stationarity, the ration of signal-to-noise, etc.). To improve and ensure minimum video quality at reception, we propose in this work a mechanism entitled “Secure and Efficient Transmission of Videos in VANET (SETV)”. It's based on the "Quality of Experience (QoE)" and using hierarchical packet management. This last is based on the importance of the images of the stream video. To this end, the use of transmission error correction with uneven error protection has proven to be effective in delivering high quality videos with low network overhead. This is done based on the specific details of video encoding and actual network conditions such as signal to noise ratio, network density, vehicle position and current packet loss rate (PLR) not to mention the prediction of the future DPP.Machine learning models were developed on our work to estimate perceived audio-visual quality. The protocol previously gathers information about its neighbouring vehicles to perform distributed jump reinforcement learning. The simulation results obtained for several types of realistic vehicular scenarios show that our proposed mechanism offers significant improvements in terms of video quality on reception and end-to-end delay compared to conventional schemes. The results prove that the proposed mechanism has showed 11% to 18% improvement in video quality and 9% load gain compared to ShieldHEVC.
Method of Detecting Radio Signals using Means of Covert by Obtaining Information on the basis of Random Signals Model

Published: December 2022

The article presents a developed method for determining random radio signals. Random signals can be signals from hidden means of obtaining information.The signal is considered as a random process. The description of such signals is based on probability theory and the theory of random functions. In the practice of analysis of random radio signals, static methods based on the theory of stationary random functions have become widespread. The existing models of a stationary random process are not adequate for a large number of random processes, especially for processes that are dynamic in nature and are observed during a finite time interval.The developed method allows to detect signals from hidden means of obtaining information with greater efficiency. The novelty of the method is to determine the deviation of the main parameters of the signals from the function of the sample. The method is based on determining the function of a sample of signals of a given radio range. The function of the sample is obtained as the implementation of the smoothing function of a random process, by the method of least squares using the principle of sliding smoothing.It is proposed to determine the signals of the means of covert receipt of information by the instantaneous deviation of the parameters of random signals. To determine the signals of the means of covert obtaining information, it is proposed to determine the deviation of the amplitude of the random signals from the amplitude of the signals of the sample function, then, if necessary, to determine the deviation of the signal phases. So, the effectiveness of the method is achieved by determining two parameters of the deviation of the amplitude and phase. This makes it possible to detect random signals with a higher probability.Determining the function of the sample of the required radio band significantly increases the probability of determining random signals, by reducing the scanning time of a given radio band, by excluding known signals from the additional software analysis of a given radio band.

To evaluate food frequency and verify the association with nutritional and anthropometric profile in adolescents. Sociodemographic and anthropometric data were collected, as well as a three-day food record to identify food frequency, whether or not breakfast was served and the average consumption of dairy products and ultra-processed foods. Sixty-three adolescents aged 14 to 16 years, mostly females (61.9%), participated in the study. In none of the associations it was possible to identify significant differences, however it was observed: consumption of ≥4 meals a day present in 60.3% of the adolescents, being linked to overweight; low consumption of dairy products in both genders and high consumption of ultra-processed foods among younger people. The breakfast variable did not establish an association with the nutritional status of the sample. There was no relation found between food frequency and the nutritional and anthropometric profile in adolescents. However, further studies should be encouraged.

Unmanned Aerial Vehicles are electronic systems that are used extensively in every field today and that develop and change very quickly with technology. UAVs are used extensively in many areas, especially in logistics processes, search and rescue activities, military operations, fight to forest fires, photography, monitoring and inspection of agricultural processes. Furthermore, considering their hobby use, it is understood that UAVs have a large commercial market and a high economic value. UAV systems contain many electronic and mechanical systems and many performance criteria can be found for UAV systems. The main ones of these performances are stabilization and engine power. The most important system affecting these performance criteria is the engine. In this study, engine alternatives available in the market for UAVs with take-off weights of 750 to 800 grams were evaluated in terms of mechanical and physical criteria of engine systems, and as a result, the ideal engine model was determined by Analytical Hierarchy method for maximum stabilization and velocity purposes. The article is the first in the literature in terms of the problem obtained and the application of the AHP method to this problem. Thanks to the study, it is aimed to create a Decision Support System for both UAV manufacturers and UAV users so that they can choose the ideal models in engine selection processes.

The translation is a cognitive activity, while humans, as cognitive subjects, have different ways of thinking. This condition has implications for the difference in translation results; infrequently, the translation results need to be clarified for the reader. Therefore, an investigation into the problems of learning Arabic needs to be carried out to minimize the emergence of a generation of incompetent Arabic translators. This study aims to investigate the psychological dynamics that occur in a person to cause differences in the way of thinking in Arabic translation. This research is qualitative research using a multi-case approach. The research subjects consisted of 10 Nurul Ummah students as a single-case analysis and 4 LSQ Ar-Rohmah students as a cross-case analysis. The data collection technique used interviews and documentation to assess translated results by expert Arab-Indo translators. Data processing to data visualization implemented NVivo 12 Plus analyzing the suitability of patterns between single and cross-case cases by synchronizing interview transcription results and translated values. The results of the data analysis found several problems that caused differences in the way of thinking of participants in Arabic translation. First, the difference in the weak structural representation of nahwu-shorof due to the difference in the age of knowledge acquisition, the number of activities participated in by participants, and the selection of the priority scale of selected activities; second, differences in inferential planning accuracy due to differences in participant habituation in Arabic translation.

This research aims to determine how parents’ treatment of children significantly contributes to the child’s personality. Quantitative descriptive research has a population of 5,378 students of SMP Islam Education in Medan. The research sample was 818 students. The results found that the personality dimensions of neuroticism reflected stressful, irritable, unrealistic, anxious, and restless behaviors. Authoritarian parenting style harmed neuroticism personality. In addition, a regression coefficient of 0.10 (p = 0.05) was also found for openness personality. Therefore, authoritarian parenting had a positive effect on open personality. The democratic parenting variable had a regression coefficient of 0.87 (p0.001), 0.82 (p0.001), 0.57 (p0.001), and 0.56 (p0.001) for personality openness, conscientiousness, extraversion, and agreeableness. Parents are influential in developing a student’s personality because it affects emotional maturity, desire for achievement, social skills, and personal maturity related to student personality dimensions. Thus, parents must apply authoritarian parenting to discipline children, shaping them to have positive personalities.

Background: Post adenotonsillectomy coughing and laryngospasm in children entails deleterious sequelae, warranting continued search for effective prophylaxis. The aim was to determine the prophylactic efficacy of intravenous mini-dose (0.1 mg/kg) suxamethonium, 1.5 mg/kg lidocaine 1%, and their combination, against coughing and laryngospasm in children emerging from general anaesthesia after adenotonsillectomy.Methods: Ethical approval and parental written consent secured, 69 children, aged 1-6 years, of American Society of Anesthesiologists (ASA) class I were randomized into groups A, B, and C, of 23 each. All patients had general anaesthesia induced with propofol 2 mg/kg plus fentanyl 2 µ/kg, maintained with isoflurane 1-1.5% in 100% oxygen, and tracheal intubation facilitated by pancuronium 0.075 mg/kg. Two minutes after reversal dose of neostigmine, groups A, B and C respectively received 1.5 mg/kg lidocaine 1%, suxamethonium 0.1 mg/kg, and 1.5 mg/kg lidocaine 1% plus suxamethonium 0.1 mg/kg, intravenously. Tracheal extubation was done 90 seconds after study drug administration, and coughing and laryngospasm were assessed for 10 minutes using modified Minogue and Likert 4-point scales respectively.Results: All 69 subjects completed the study. The incidence of mild to moderate coughing was 22 (95.7%) in groups A and B, and 19 (82.6%) in group C, p=1.000. Laryngospasm occurred in none (0.0%) in group C, while in groups A and B its occurrence was 1(4.3%), p=1.000.Conclusions: Mini-dose suxamethonium or lidocaine 1.5 mg/kg prevented grade 3 coughing and laryngospasm; furthermore, their combination prevented grade 3 coughing and achieved zero incidence of laryngospasm.

Published: December 2022

Background: Maternal vitamin D insufficiency has been linked with increased risk of preeclampsia. Despite this, the evidence regarding the efficacy of vitamin D supplementation in preventing preeclampsia is controversial. The aim of study was to collate the incidence of preeclampsia in high-risk females with vitamin D supplementation versus placebo.Methods: The present study was a randomized controlled trial. The study was conducted in the department of obstetrics and gynecology, Madinah Teaching Hospital affiliated with University Medical and Dental College Faisalabad. The study was collected over one year from July 2019 to June 2020. Patients were randomly assigned to two groups. Patients in group-A were given vitamin D supplementation of 600 IU daily. The control group (group-B) was given placebo. If blood pressure (BP) ≥140/90 mmHg and proteinuria found positive in urine, then preeclampsia was labeled (as per operational definition). Both groups were compared for preeclampsia by using Chi–square test. P value <0.05 was taken as significant.Results: The incidence of preeclampsia was 4% (n=2/150) in group A and 8% (n=6/150) in group B developed preeclampsia. The difference was (p value=0.3) insignificant difference.Conclusions: Vitamin D addition in pregnancy did not demonstrate a statistically significant effect of vitamin D on the prevention of preeclampsia.

Published: December 2022

Background: Stroke is defined as an abrupt onset of a neurologic deficit lasting for more than 24 hours that is attributable to a focal vascular cause. Hyperglycemia and dyslipidemia are often documented in stroke patients. Elevated CRP level is independently associated with the excessive risk of ischemic stroke. Aim and Objectives were to evaluate the glycemic status, lipid profile and c-reactive protein level in stroke patients admitted in a teaching institute of north-east India.Methods: A cross-sectional hospital-based study conducted in the department of medicine, Agartala Government Medical College and GBP hospital, within a period of January 2020 to June 2021. Data were analyzed by SPSS software version 15 using appropriate statistical tests.Results: Among 200 patients of stroke, 50% was found to be pre-diabetic, 40% known diabetic and 10% newly diagnosed diabetic. 60% were hypertensives. Among them, 80% had ischaemic stroke and 20% hemorrhagic stroke. 70% of the patients had hypercholesterolemia, 60% had hypertriglyceridemia. 80% had raised serum LDL and 57% decreased serum HDL. Out of 200 patients, 60% was found to have raised serum CRP level. 55% of ischaemic stroke patients and 5% of hemorrhagic stroke patients had raised CRP level.Conclusions: Prediabetes and newly diagnosed diabetes are highly prevalent in patients with stroke or TIA. As the prevalence of prediabetes is growing rapidly, prediabetes might become one of the most important modifiable therapeutic targets in both primary and secondary prevention. Early detection of dyslipidemia and treatment with drugs along with dietary modifications and lifestyle changes can reduce the risk of stroke. Since, it was a cross-sectional study, these results need to be validated by further long-term prospective studies.
