Minimizing the uncertainties related to the tunnels’ construction parameters is a crucial task that need to be addressed. Usually, the most uncertainties in underground structures are related to the unknown geological status. In order to probabilistically estimate these uncertainties, variety techniques have been developed, including the Markov method. This study is undertaken on a road tunnel in Iran in order to forecasting the geological status along its route using the Markov method. To access the Markov’s model input data, a number of questionnaires were distributed among the tunneling experts and eventually the mean values of the respondents were used in the model. In the next step, the results predicted by the Markov model were compared with the actual ones to evaluate the model performance. Finally, the Markov model was suggested as a powerful tool to predict tunnels’ path geology.

Parkinson's disease is a degenerative nervous system condition that impairs mobility. If the condition is not detected early enough, it might have permanent effects for the sufferer. A novel approach for identifying Parkinson's disease is provided in this research, which employs machine optimization and learning techniques. The suggested method's diagnosis procedure may be broken down into three primary steps: "preprocessing," "feature extraction," and "classification." Preprocessing the EEG data is the initial stage in the suggested technique. Database samples are treated using discrete wavelet analysis to remove the destructive influence of noise on the input signals using signal analysis for this aim. The suggested method's second phase will employ principal component analysis to remove duplicate features and minimize data dimensionality. The artificial neural network model is trained and the classification model is built using the retrieved features. The effectiveness of the suggested technique is examined in terms of criteria such as accuracy, sensitivity, and specificity during the experimentation phase, and the results are compared to existing learning models. The findings revealed that the suggested technique enhances illness diagnostic accuracy by at least 8.25% and may be utilized as a useful tool in disease diagnosis.

Increasing demand for tunneling projects, increases attention to time and cost required for their construction. Most of parameters which are affecting on the time and cost of tunnel construction are unknown. The purpose of this paper is to provide a method to predict the construction time and cost of a road tunnelusing linear regression (LR) method. In order to train the LR method, some datasets are obtained from the historical road tunnels. To verify the feasibility of the proposed method, it has been applied to a road tunnel. All of the forecasted results have been compared with the actual results obtained during the tunnel construction and the accuracy of the predictions has been investigated. According to three statistical evaluation criteria of root mean square error (RMSE), mean absolute percentage error (MAPE) and determination of the coefﬁcient (R2), a very high accuracy has been obtained in the prediction results. The RMSE, MAPE and R2 indices have been calculated as 0.0005 days, 0.9380637% and 0.9874 for the construction time, respectively; and 7.1194 US$,0.78891593% and 0.9873 for the construction cost, respectively.

Face detection and authentication have become an active field of research material in recent years duo to the increased use of face dependent access control systems, which can be considered as a good alternative to other biometric features such as fingerprint duo to its easily accessible, non- intrusive nature that makes it very important during the ongoing pandemic years. However, this method doesn’t come without security risks related to adversaries seeking to gain unauthorized access to the system. Face spoofing is a security breach attempt occurs when the attacker tries to deceive the face-enabled access control system by displaying a photo, video or wearing a mask of an authorized person to gain access. The paper in hand suggests a method for face anti-spoofing by utilizing some of the well-known feature extraction techniques usually associated with face detection and recognition, namely the LBP and Gabor features, in addition to the commonly used SVM classifier for identifying real and spoofed feces. The algorithm is implemented successfully on multiple individuals, achieving performance levels comparable to other accredited methods in terms of FAR, FRR and HTER verification criteria, aspiring for more advancedand effective methods.

Authors: Abubakirova M. I.
Published: August 2022

Introduction. Entry into science should occur from the first year of university. One of the main barriers is the inability to work with scientific information. In order to improve the competitiveness of students in the scientific environment, a study of the level of information culture of students enrolled in the first year of undergraduate studies was conducted.

Materials and methods. The main research method is a selective Internet questionnaire survey. The main method of information analysis is the method of constructing typologies, the essence of which is to find such empirical indicators that would sufficiently adequately reflect the levels of competitiveness in research activities and the corresponding types of applicants to a technical university in the digital era.

Results. During the survey, it was revealed that the majority of respondents do not have an understanding of the basics of design as a method of work, there are no skills in building an experiment, using methods of analysis and synthesis, there is no understanding of the importance of publishing the results of their work. More than 90 % of respondents have an average level of information culture with good skills in owning applied office programs.

Discussion and conclusions. It was concluded that in order to achieve competitiveness in the scientific environment of students, it is necessary to teach information culture almost from scratch.

Published: August 2022

Objectives: The aim of this study were: 1. To report facial soft tissue measurements in Class I Malay adult, 2. To compare between gender, 3. And to check applicability of Holdaway values for Class I Malay adults. Materials and Methods: Lateral cephalometric of 20 men and 20 women age 20-30 years with Class I skeletal was selected from Orthodontic Clinic, Faculty of Dentistry UiTM. The subject has no orthodontic or orthognathic surgery done before the radiograph was taken. The radiograph was traced and evaluated by the authors. Cephalometric landmarks were located according to Holdaway analysis. Ten linear and two angular measurements were produced on each radiograph and measured. For each variable, the mean and standard deviation (SD) was calculated using simple t-test (p<0.05). Results: Soft tissue measurements for Malay have significant difference as compared to Holdaway value except for three parameters which are soft tissue facial angle, superior sulcus depth, and soft tissue chin thickness. When compared between genders, male has larger value in skeletal profile convexity, upper lip strain and soft tissue thickness while females demonstrated higher value in nose prominence and superior sulcus depth. Conclusions: It has been concluded that Malay values for Holdaway soft tissue analysis were found to be statistically different. Hence Holdaway soft tissue values are not applicable for use in orthodontic practice for Malay population. Further research to confirm values obtained for Malay population would aid in better diagnosis and treatment planning.

Published: August 2022

Objectives: This study aimed to analyze the therapeutic potential of plant extract against oral microorganisms in published literature. Material and Method: A systematic literature review was performed through electronic databases (Scopus, EBSCO: Dentistry and Oral Science Source) from January 2009 till December 2019 with the search terms (“extract” AND (“ORAL MICROORGANISM” OR “ORAL BACTERIA”) AND (“stem” OR “Bark” OR “Leaf”)). Results: Out of 409 articles, 21 articles met our inclusion criteria that were subjected to data extraction and review. The data disclosed antimicrobial and antibiofilm activity of plant extracts against causative microorganisms of caries, periodontitis, endodontic infection, and fungal infection. Ethanol was the most common solvent used for plant extraction. The antimicrobial test was reported in all studies using different methodologies such as minimum inhibitory concentration (MIC), disk diffusion method, agar well method, intracanal irrigation, and Fractional Inhibitory Concentration Index (FICI) . None of the plant extract tested showed significant toxicity in five studies that conducted toxicity assays. Conclusion: A positive correlation was observed between plant extract and antimicrobial activity against oral microorganisms. In that context, integrating plant extract in oral healthcare products could be an option to enhance effective antimicrobial control. However, further clinical studies are required to provide clinical evidence to support these observations.

Authors: Mohd Yusof E
Published: August 2022

Tooth wear is prevalent in the society and often-time affects an individual’s daily life. This case demonstrates the management of non-carious tooth surface loss with loss of occlusal vertical dimension using multidisciplinary approach involving periodontics, endodontics and prosthodontics. The tooth surface loss was graded moderate to severe anteriorly and affecting the patient’s overall appearance and self-confidence. Rehabilitation of this case involves restoring the anterior teeth at an increased occlusal vertical dimension, using reorganised approach and allowing relative axial tooth movement posteriorly. Clinical Relevance: The author believes the understanding of available conservative treatment options, occlusion concepts, proper material handling and satisfactory communication with other disciplines and the laboratory aid a clinician in achieving the best treatment outcome and better patient satisfaction.

Published: August 2022

A basic purpose of a good healing patch is to reduce the reproduction of bacteria in the wounded area with minimal effect of mechanical properties. This study focuses on the basic mechanical and biomechanical properties of the material for a healing patch application with a new composition of biodegradable ingredients by using the estimation of hyperelastic models to fit with the experimental data and the comparison between the commercial Aloe vera gels and original Aloe vera leaves. This project was started with a material selection which is gelatine and Aloe vera leaves as the main ingredient. Secondly, the specimen sets undergo a uniaxial tensile test to obtain the raw data. For numerical phases, the conventional theory of large deformation based on hyperelastic constitutive equations and Stress-Strain Energy Theory were identified. The final step for this project is curve fitting between experimental data (Ogden and Mooney-Rivlin hyperelastic models). New parameters were carried out for healing patch materials made of hybrid biomaterials from the hyperelastic theory. The Ogden and Mooney Rivlin trends were closely followed by the curve fit presented with a minor difference. Overall, the original Aloe vera leaves’ values were Ogden (α=1.8792, µ=0.1881 Mpa) and Mooney-Rivlin (C1=0.0713, C2=0.0304) respectively. The significance of this project is to expand the knowledge about mechanical properties of natural polymers for wound healing application instead of depending on semi-synthetic polymers.

Published: August 2022

Hojas sueltas fue un tipo de publicación que circuló en Colombia durante la segunda mitad del siglo XVIII e inicios del siglo XIX. Fueron publicaciones cortas y no seriadas que propendían por la divulgación de aspectos diversos de la vida cotidiana, como la cultura, la religión, la economía y la política. “Conversación entre un zapatero y un agrícola de Facatativá sobre la cazería[sic] del Sábado Santo” es un cuento publicado en 1839 en Bogotá por la imprenta José Ayarza, bajo dicho formato de publicación. A través de un análisis de corpus textual, usando la herramienta Voyant Tools, en este artículo se proponen dos mecanismos analíticos: una comparación intertextual e intradiegética de los tres sitios web donde se encuentra alojada la versión digitalizada del cuento y una descripción de líneas discursivas a partir de reseñas críticas elaboradas por estudiantes de literatura. Se concluye que Voyant Tools es una herramienta útil para describir líneas discursivas de un corpus textual, y que puede servir de insumo para realizar análisis del discurso o de tendencias temáticas presentes en las opiniones y reflexiones de un colectivo.

POSSIBLE USE OF MATHEMATICS AND REASONING IN PROBLEM-SOLVING PROCESS OF SEVERAL CHEMICAL PROBLEMS
Authors: TSIRUNYAN VAHAGN , ADONTS HOVHANNES , GYULBENKIAN ZHAN
Published: August 2022

Nowadays it is important to use various approaches, methods and tricks during teaching process of chemistry helping students gain new knowledge. Using interdisciplinary relations, we show the use of concept of similar triangles and mathematical reasoning during problem-solving process of chemical problems.

In “Solutions” section it is shown how to apply concept of similar triangles and corresponding formula is derived. Patterns observed here exactly match the properties of well-known concept of similar triangles, which gives possibility to solve problem using mathematical tricks and methods. The formula is used to calculate the mass of precipitate formed caused by the drop of temperature of a saturated solution. In another example, in order to solve the problem, it is needed to solve a triangle equation, which is done using mathematical reasoning and concepts taught at school. It is well known that school knowledge may be insufficient to solve triangle equations. It should be noted, that majority of unknown values in chemical problems can be expressed using discreet values, which allows to solve problem by redefining it to mathematical divisibility problem.

We provide solutions to chemical problems that don’t involve much of chemical reasoning. Suggested solutions broaden learners’ mind and enhance creative thought.
LINGUA-PHILOSOPHICAL PERCEPTIONS OF A LINGUISTIC SIGN, SIGNIFICATION, MEANING AND THE LINGUISTIC PICTURE OF THE WORLD
Authors: MARTIROSYAN ARTASHES
Published: August 2022

The article discusses the questions raised in correlation with the reflection of the linguistic picture of the world and still causing philosophical concerns: What is the ratio? Is it “complicity” that exists between a word and its meaning? What is their “degree of independence”? Does the word help to form thoughts or meaning? Which of them prevails? Are there other significant components in forming the linguistic picture of the world? In the context of these issues, the provisions of the world’s leading lingua-philosophical streams in different periods of history regarding the complementary role of verbal sign, meaning and sense in the process of creating the linguistic picture of the world are presented. If the meaning is constant in all languages and the word is a carrier of certain information, what is the nature of invariants in the formation of the meaning of the word given for the same concept in different languages, associated with worldview of this linguistic community? Maybe this difference is connected with the reality of modelling the world.

However, the conceptualization of the world through the language, sign is universal and nationwide, while the peripheral ones are linguistic and national, still remains pendent in linguistic semantics.

The formation of legal culture of modern youth is covered in multidisciplinary issues of legal culture, legal awareness of man and young people in particular, legal education, training in pedagogical, psychological, philosophical, sociological, political, economic sciences, culture, public administration and social communications. Legal consciousness is formed in the process of personal development. The humanistic nature of the formation of modern youth’s legal culture is represented by the embodiment of social self-movement, which requires general scientific structure and typology of methods of cognition and transformation of reality in their development and relationships. The main methodology of formation of legal culture as a phenomenon and process is defined by the idea of ​​development.
TEACHING PECULIARITIES OF FACIAL EXAMINATION AND COMPLETE DENTURE FABRICATION IN DENTAL EDUCATION FOR STUDENTS AND CLINICAL RESIDENTS
Authors: HEBOYAN ARTAK
Published: August 2022

Esthetic restorations are essential to success in modern dentistry. Unfortunately, assessing the patient's aesthetic expectations and aesthetic prognosis during the initial evaluation can be problematic. A thorough facial research, involving collaboration with the patient, is an important element in the premedical protocol. It is very important to present the importance of facial contours and their change during tooth restoration to students and clinical residents of the Faculty of Dentistry. Identification of midline asymmetries, lip disharmony, excessive visibility of prosthetic abutments, as well as facial shape, vertical/horizontal relationships of residual caries affect both treatment modality and prognosis. Assessment of these esthetic factors by the dentist and the patient prior to initiation of treatment is best accomplished by clinical photography.

Genetics is one of the hard to learn biological concepts owing to its connectedness to Latin / Greek origin. Hence, the need for its proper structuring for easy comprehension by the students. The effectiveness of text structure on students’ proper understanding had been widely reported in literature, hence, this study investigated score levels, text structures and senior secondary school students' achievement in genetics. Specifically, the study assessed the: (i) variation in the achievement of students taught using different text structures (ii) interaction effects of text structures and score levels on senior school students’ achievement in genetics among others. A quasi-experimental design of pretest, posttest, non-equivalent, and non-randomized control group was adopted. A total of 239 students purposively selected took part in the study. ANCOVA was used to analysed the hypotheses at 0.05 alpha level. Findings indicated that there was (i) a statistically significant difference in the achievement of students exposed to different text structure i.e., F (2, 238) = 15.11 at p < 0.05; (ii) no statistically significant difference in the interaction effects of text structure and score level. The implication of the finding is that the two structured texts were useful for improving senior school students’ achievement in genetics. It was therefore, recommended that biology teachers should consider logical prose and concept maps in structuring their instructional materials.

Rhinosinusitis is one of the most common conditions in primary and secondary care all over the world. Rhinosinusitis together with asthma and gastroesophageal reflux disease represent the most common causes of chronic cough. The relationship between rhinosinusitis and cough is still not completely understood, however, direct stimulation of nasal mucosa, upper airway cough syndrome, inflammation of the airways, and cough reflex sensitisation play the crucial role in the pathogenesis of chronic cough.

Published: August 2022

Introduction

The Omicron variant rapidly outpaced Delta with documented community transmission in most countries and has led to an upsurge in cases in most regions. Since its initial detection from a specimen collected on November 8th 2021, Omicron amounted to 74.0% of the genome sequenced in South Africa and more than 99.0% in rest of the world.

Objectives

1. To describe the socio-demographic and clinical profile of Omicron cases treated at our tertiary care institution. 2. To assess the factors associated with the vaccination status of such Omicron cases.

Methods

This observational study was conducted at a 500 bedded hospital in southern India from 15th of December 2021 to 5th of February 2022. Of the 333 COVID-19 patients who were registered with Reverse Transcription-Polymerase Chain Reaction (RT-PCR) positive result along with S Gene Target Failure (SGTF), 203 patients were included and were interviewed using a pre-designed semi-structured questionnaire. With prior approval from the Institutional Ethics Committee (IEC) data was collected and statistically analyzed with descriptive statistics and inferential statistics using SPSS software trial version 28.0 and OpenEpi software. At 95% confidence level, a P value of < 0.05 was considered as statistically significant.

Results

Of the 203 cases studied, majority 149 (73.4%) were symptomatic, of which almost 114 (76.5%) had fever, 72 (48.3%) had cough and 29 (19.5%) had myalgia. 193 (95.1%) cases were categorized as mild, 8 (3.9%) as moderate and 2 (1.0%) as severe cases of COVID-19 with SGTF. Only 10 (4.9%) patients received supplementary oxygen support. Almost 158 patients (77.8%) were vaccinated against COVID-19 of which 106 (67%) were vaccinated with Covishield vaccine followed by 50 (31.7%) of them with Covaxin. 126 (79.7%) patients were completely vaccinated with two doses of any COVID-19 vaccine and 32 (20.3%) were partially vaccinated with a single dose of any COVID-19 vaccine. Among those who required supplemental oxygen (n = 10), the proportion of those vaccinated (40.0%) was lower com pared to those who were unvaccinated (60.0%). This association was statistically significant (P = 0.003, OR = 0.169, 95% CI of OR = 0.045, 0.628). Among the completely vaccinated subjects (n = 125), there was a statistically significant difference in mean (95% CI) interval between the last dose of vaccine taken and date of RT-PCR positivity with SGTF (P < 0.001). It was 186 (162, 210) days for Covaxin and was 131 (114, 148) days for Covishield vaccine.

Conclusion

Omicron (SGTF) cases manifests mostly as mild cases with symptoms like fever, cough, myalgia and majority were independent of oxygen supplementation and had good prognosis. Omicron infection was delayed over six months among completely vaccinated subjects especially those who were vaccinated with Covaxin.

Background

Magnesium sulphate (MgSO4) has been proven as an analgesic, neuromuscular blocker agent, and treatment of acute asthma.

Objective

The study aimed to assess the safety and efficacy of magnesium sulphate infusion for the treatment of patients with atrial fibrillation.

Methods

A prospective, randomized, double-blind, placebo-controlled study was conducted on 55 atrial fibrillation patients at the Emergency Department. The treatment group consisting of 41 patients received 20 mEq (2.5 g, 10 mmol) magnesium sulphate over a 20-minute period, followed by 20 mEq (2.5 g, 10 mmol) over a 2-hour period intravenously in addition to the standard treatment, and the control group consisting of 14 patients received placebo with a standard treatment. ECG was repeated and monitored upto 24 hours after the infusion.

Results

41 patients received magnesium sulphate and 14 patients received a placebo. The heart rate was 127 bpm – 210 bpm at the presentation to the emergency department and it was reached <100bpm in 70%(n=31) patients after 150 minutes of MgSO4 infusion. Two patients attained a heart rate of <100bpm in Placebo infusion. In the treatment group, 65% of subjects attained normal sinus rhythm at the end of 24 hours of infusion. Magnesium sulphate was more likely than placebo to achieve a heart rate of <100bpm and more likely to convert to sinus rhythm. ECG report reverted to normal in 74.5% in the treatment group and 25.5 % in the Placebo group within 24 hours. The patients in the treatment group stay a mean of 2.25 days in ICU, while the patients in the Placebo group stayed 4.25 days in ICU. Seven patients in the treatment group had minor side effects like flushing, headache, and nausea, which came to normal after 48hrs.

Conclusions

Magnesium sulphate has been shown a better efficacy to control the heart rate and conversion to sinus rhythm when used along with the standard management of Atrial fibrillation.

Published: August 2022

The world is heading towards more modernized and digitalized data and therefore a significant growth is observed in the active number of social media users with each passing day. Each post and comment can give an insight into valuable information about a certain topic or issue, a product or a brand, etc. Similarly, the process to uncover the underlying information from the opinion that a person keeps about any entity is called a sentiment analysis. The analysis can be carried out through two main approaches, i.e., either lexicon-based or machine learning algorithms. A significant amount of work in the different domains has been done in numerous languages for sentiment analysis, but minimal research has been conducted on the national language of Pakistan, which is Urdu. Twitter users who are familiar with Urdu update the tweets in two different textual formats either in Urdu Script (Nastaleeq) or in Roman Urdu. Thus, the paper is an attempt to perform the sentiment analysis on the Urdu language by extracting the tweets (Nastaleeq and Roman Urdu both) from Twitter using Tweepy API. A machine learning-based approach has been adopted for this study and the tool opted for the purpose is WEKA. The best algorithm was identified based on evaluation metrics, which comprise the number of correctly and incorrectly classified instances, accuracy, precision, and recall. SMO was found to be the most suitable machine learning algorithm for performing the sentiment analysis on Urdu (Nastaleeq) tweets, while the Roman Urdu Random Forest algorithm was identified as the best one.
