Abstract
Objective: To determine the frequency of learning styles of medical students by using David Kolb’s learning style inventory and its association with preferred teaching methodologies.
Methods: A cross-sectional study was carried out among over 500 medical students of Baqai Medical College, Baqai Medical University, Gadap, Karachi, form July 2019 to October, 2019. David Kolb’s learning style questionnaire, and a 2nd questionnaire to know preference for different teaching methodologies were distributed to the students. Learning styles were identified and their association with preferred teaching methods was checked by Chi-square test.
Results: The mean age of the medical students was 21.5±1.69 years. Two hundred and thirteen (40.7%) participants were males and 310 (59.3%) females. By learning styles, 268 (51.7%) medical students were divergers, 118 (22.8%) were assimilators, 86 (16.6%) were accomodators and 46 (8.9%) were convergers. A significant association was found between learning styles and selected teaching methodologies such as interactive lectures (p=0.013), small group discussion (p=0.039) and self-study (p=0.032) while problem based learning, demonstration on models, lab work, one-way lecture and student presentation were not found to be significantly associated with learning styles.
Conclusion: Majority of the medical students had diverger (51.7%) and assimilator (22.8%) learning styles. The teaching methodologies of interactive lectures, small group discussion and self-study were found to be associated with learning styles. Aligning our instructional strategies with learning styles of the medical students will improve learning and academic performance.

Oxidative Stress, Vitamin D Deficiency and Male Infertility: An Under-Looked Aspect
Authors: Maheen Shahid  , Syeda Amrah Hashmi  , Rehana Rehman  , Admin
Published: January 2021

Dear Madam,
Infertility is a known source of distress among couples worldwide. This agony significantly stems from the concern of not having an identifiable cause leading to infertility. With male factors accounting for 20-30% of the total causes of infertility (1), a thorough evaluation of both the partners is done.
Upon evaluation, Vitamin D deficiency was noticed significantly in males coming to infertility centres. However, its functions and how it impacted reproduction was not known until the research led to the discovery of Vitamin D Receptor (VDR) in many organs of the male reproductive tract. It is now known that vitamin D deficiency decreases male fertility by contributing to oxidative stress and gonadal insufficiency, disrupting spermatogenesis, affecting sperm morphology and normal calcium haemostasis. (2)
Oxidative stress, caused by an imbalance between oxidative and antioxidative mechanisms, is believed to be a well-known mechanism underlying idiopathic male infertility. Reproductive health professionals and researchers fittingly started searching for antioxidants to combat this imbalance. A study concluded that adding vitamin D to a cryopreserved semen sample reduced oxidative stress and resulted in better fertility outcomes (3). Animal trials have shown that Vitamin D supplementation reduced oxidative stress and improved semen DNA integrity (4).
As Vitamin D exerts its effects by binding to Vitamin D receptors, it was noted that vitamin D receptor null mutant mice had a significant reduction in successful reproductive outcomes due to gonadal insufficiencies. Reduced levels of oestrogen and testosterone were seen along with low sperm count, reduced motility, abnormal spermatogenesis and histological abnormalities in testes of mutant mice. These insufficiencies were attributed to a decreased CYP2R1, CYP27B1 and CYP24A1 expression, lower aromatase activity, secondary to suppression of CYP19 gene and calcium supplementation improved fertility in such cases. (5)
There is limited human data available on how Vitamin D deficiency causes gonadal insufficiency, which is important to maintain normal reproductive physiology. More studied are needed to clarify the role of vitamin D in gonadal physiology. Considering the importance of Vitamin D on reproductive functions, its role in causing Oxidative stress and gonadal dysfunction, we suggest randomized control trials in pre-pubertal phase.

Abstract
A cross-sectional survey was conducted from February 2016 to September 2016 to assess knowledge, attitude and practices regarding implants among women of childbearing age visiting Reproductive Health Services Center, Civil Hospital,Karachi. A total of 396 adult non-pregnant married females of child bearing age, from 18 to 49 years old, were interviewed using a structured questionnaire.Only153 (38.6%) of therespondentshad knowledge about implants whereas out of them 122 (79.7%) acquired it from family planning clinics. Almost two third of them (n=267, 67.4%) were in favor of using implants as a contraceptive method. Moreover, 244 (61.6%) of them were of the opinion that if given the choice, they will use implanon though out of total 316 (79.8%) respondents who ever used contraceptives, only 3 (0.9%) used implants.Despiteafavorable attitude, limited knowledge and poor practices of the respondents highlighted the study findings.

Authors: SOMTRAKOON Khanitta , CHOUYCHAI Waraporn
Published: January 2021

Plant growth regulators and synthetic surfactants are choices for enhancing the efficiency of PAH phytoremediation. In this study, the use of salicylic acid alone, surfactant alone (Triton X-100 or Tween 80), or salicylic acid together with Triton X-100 or Tween 80 on anthracene and fluoranthene removal by Impatiens balsamina were investigated. On days 15 and 30 of the experiment, the spraying of salicylic acid as 0.01 mM and watering of 1X CMC of Triton X-100 or Tween 80 were performed. Then, the plant growth parameters and anthracene or fluoranthene remaining in the soil were analyzed on day 45 of the experiment. The results revealed that I. balsamina did not enhance anthracene (77.4 % remained) and fluoranthene (74.6 % remained) removal when compared with unplanted soil (63.8 % of anthracene and 70.0 % of fluoranthene remained). Salicylic acid spraying in combination with watering of Triton X-100 (47.1 % anthracene remained) or Tween 80 (59.7 % anthracene remained) enhanced anthracene removal in unplanted soil; however, enhanced fluoranthene removal was not observed. In planted soil, salicylic acid spraying alone, Tween 80 watering alone or salicylic acid spraying in combination with synthetic surfactant (Triton X-100 or Tween 80) watering slightly enhanced anthracene removal (54.9-58.0 % of anthracene remained) but not fluoranthene (67.9 - 81.9 % of fluoranthene remained). The results revealed that planting contaminated soil with I. balsamina was not suitable to stimulate anthracene and fluoranthene degradation in this study. Biostimulation of unplanted soil with synthetic surfactant and salicylic acid was suitable to stimulate the removal of anthracene from the soil.

Socio-Organo Complexity, Project Schedule Performance and Underdamped Transient Motion
Authors: N. Antoniadis Dimitris
Published: January 2021

Complexity is an inherent property of all systems and a result of interconnections. In projects various systems come together to deliver the required outcome(s). The most common type of project complexity mentioned / considered in practice is the technical complexity and this has always been considered a main factor which affects project performance. Despite that, projects are delivered by people who interface ontinuously and therefore are effected by complexity, and in particular that caused by socio-organo interfaces and the boundaries between the various teams and parties. This has not been investigated. ocio-organo complexity leads to reduction in performance if interconnections are not managed. Research has been carried out to understand the effects of complexity through project management processes on project schedule and performance, aiming towards the development of a tool and identification of actions that will enable the management of these effects. The author presents results of five case studies, which demonstrate that socio-organo complexity affects performance and these results have similarities with the behaviour of underdamped control systems. The results have significant implications on the way socioorganisational complexity can be managed, how processes are implemented, but also enable parallels to be drawn between the fields of project management and control systems. Considering control systems theory proposals are made in this paper for actions to be taken which will contribute towards the management of the effects of socio-organo complexity on projects.

Adaptive Vocabulary Construction for Frustration Intensity Modelling in Customer Support Dialog Texts
Authors: Zuters Janis , Leonova Viktorija
Published: January 2021

This paper examines emotion intensity prediction in dialogs between clients and customer support representatives occurring on Twitter. We focus on a single emotion type, namely, frustration, modelling the user's level of frustration while attempting to predict frustration intensity on the current and next turn, based on the text of turns coming from both dialog participants. A subset of the Kaggle Customer Support on Twitter dataset was used as the modelling data, annotated with per-turn frustration intensity ratings. We propose to represent dialog turns by binary encoded bags of automatically selected keywords to be subsequently used in a machine learning classifier. To assess the classification quality, we examined two different levels of accuracy imprecision tolerance. Our model achieved a level of accuracy significantly higher than a statistical baseline for prediction of frustration intensity for a current turn. However, we did not find the additional information from customer support turns to help predict frustration intensity of the next turn, and the reason for that is possibly the stability of user’s frustration level over the course of the conversation, in other words, the inability of support’s response to exert much influence to user’s initial frustration level.

Published: January 2021

A variety of goods and services in the contemporary world requires evolutionary improvement of services e-commerce platform performance and optimization of costs. Contemporary society is deeply integrated with delivery services, purchasing of goods and services online, that makes competition between service and good providers a key selection factor for end-user.. As long as logistic, timely, and cost-effective delivery plays important part authors decided to analyse possible ways of improvements in the current field, especially for regions distantly located from popular distribution canters and drop-ship delivery networks. Considering both: fast and lazy delivery the factor of costs is playing an important role for each end-user. The work proposes a simulation that analyses the current cost of delivery for e-commerce orders in the context of delivery by the Supplier Fleet, World-Wide delivery service fleet, and possible vendor drop-ship and checks of the alternative ways can be used to minimize the costs. Special attention is given to Drop-Ship networks as the factor of possible costs decrease. The main object of investigation is focused around mid and small companies living far from big distribution canters, in the rural areas but actively using e-commerce solutions for their daily activities. The authors analysed and proposed a solution for the problem of cost optimization for packages delivery for long-distance deliveries using a combination of paths delivered by supplier fleets, worldwide, local carriers and drop-ship networks. Data models and Add-ons of contemporary Enterprise Resource Planning systems have been used, and additional development is proposed in the perspective of the flow selection change for combination of carriers. The experiment is based on data sources of the United States companies using a wide range of carriers for delivery services and uses the data sources of the real companies; however, it applies repetitive simulations to analyse variances in obtained solutions for different combinations of carriers.

Published: January 2021

This study used a mixed methods approach to capture key findings on COVID-19 impacts on education and challenges that hinder continued education particularly in disadvantaged and rural areas. The respondents were 900 parents, 943 children, 15 teachers and education officials in 594 villages in 9 provinces of Indonesia. The results showed that 1 out of 3 children stopped learning and children learned less. Children had limited access to widely supported online learning. While the offline method was more applicable, still it had some challenges. Children’s mental health was affected and they experienced excessive emotions of fear and anxiety. Many parents were not ready to support children in learning school subjects while doing livelihood activities at the same time. Some children experienced domestic violence. Parents did not have a spare budget to provide distance learning facilities and had to sacrifice education over basic needs. The risk of drop out of school was heightened.
Aesthetic Intelligence and Aesthetic Experience in Children
Authors: K V Lilly , Venukapalli Sudhakar
Published: January 2021

How do children experience music, art, emotions, and beauty? Is aesthetic potential in children innate or acquired? Do children understand the world around aesthetically? Is aesthetic experience a developmental process? How can teachers provide students with opportunities to experience aesthetics for cognitive, social, cultural, and psychological development? These are some of the fascinating questions in the field of contemporary aesthetic education. This paper presents what is aesthetic experience and how it enriches the lives of children. Children should be exposed to fine arts and support from teachers will help them to find meaning in fine arts. Visual arts curriculum will help children in cognitive development by continuously constructing new knowledge and integrating it into existing knowledge. Curriculum designed to teach aesthetic experience should incorporate both art viewing and art making. Aesthetic experience integrates mind, body, and emotion. It can induce personal growth in children, and it is intrinsically satisfying.

Initially, 1346 articles on dyslexia and teaching methods, generally that were published during the last 20 years (2000-2020) were identified in 5 databases. Findings showed that, despite the very large number of publications on the subject, only a few studies (3) were found to meet our research criteria (dyslexia + geography + teaching methods + teachers’ attitudes/knowledge). It is suggested that future studies focused on teaching geography and its impact on dyslexia would contribute to drawing clearer conclusions on the topic.

A study was carried out with 33 teachers of Modern Foreign Languages (MFL) to obtain information on the interaction of classroom professionals with Computer Assisted Language Learning (CALL) and digital technologies in Second Language (L2) education. MFL teachers were recruited through Facebook groups in the UK. Research subjects were asked to fill out a questionnaire with CALL-specific statements. Significantly, participants recognised a gap in practice versus the expectation of CALL in the MFL classroom. Overall, participants were shown to be interested adopted and daily users of CALL who appreciated its ease and importance for teaching and learning in L2 pedagogy.
Performance Analysis of Spatially Correlated Cylindrical Antenna Array for 3D Massive MIMO
Authors: Danuor Patrick , Ampoma Affum Emmanuel
Published: January 2021

The spectral efficiency of three-dimensional (3D) massive MIMO is impaired due to the spatial correlation (SC) between closed-spaced elements of antenna arrays (AAs). This paper investigates the impacts of arbitrary Q-power variations of the Power Cosine distribution for a precise characterization of the SC. This is done by presenting mathematical expressions characterizing the SC of cylindrical antenna array (CAA) regarding Student's -t, Von Mises and Cosine distributions, for the direction of arrival (DoA) of the electromagnetic waves impinging on the receiving antenna. Unlike the Student's -t and Von Mises distribution, our outcome recorded huge mismatch between theoretical and simulation correlation coefficients for arbitrary Q-power values above ten (10) which also reduced the downlink channel capacity. The practical relevance is that even though higher Q-power values are the key parameters for system performance, meticulous selection of arbitrary Q-power values above ten (10) is essential to minimize errors regarding channel modelling.

Authors: Lira Cortes Ana Laura , Fuentes Silva Carlos
Published: January 2021

This work presents research based on evidence with neural networks for the development of predictive crime models, finding the data sets used are focused on historical crime data, crime classification, types of theft at different scales of space and time, counting crime and conflict points in urban areas. Among some results, 81% precision is observed in the prediction of the Neural Network algorithm and ranges in the prediction of crime occurrence at a space-time point between 75% and 90% using LSTM (Long-ShortSpace-Time). It is also observed in this review, that in the field of justice, systems based on intelligent technologies have been incorporated, to carry out activities such as legal advice, prediction and decisionmaking, national and international cooperation in the fight against crime, police and intelligence services, control systems with facial recognition, search and processing of legal information, predictive surveillance, the definition of criminal models under the criteria of criminal records, history of incidents in different regions of the city, location of the police force, established businesses, etc., that is, they make predictions in the urban context of public security and justice. Finally, the ethical considerations and principles related to predictive developments based on artificial intelligence are presented, which seek to guarantee aspects such as privacy, privacy and the impartiality of the algorithms, as well as avoid the processing of data under biases or distinctions. Therefore, it is concluded that the scenario for the development, research, and operation of predictive crime solutions with neural networks and artificial intelligence in urban contexts, is viable and necessary in Mexico, representing an innovative and effective alternative that contributes to the attention of insecurity, since according to the indices of intentional homicides, the crime rates of organized crime and violence with firearms, according to statistics from INEGI, the Global Peace Index and the Government of Mexico, remain in increase.

Authors: AbdAllah Nisreen , Viriri Serestina
Published: January 2021

The main aim of this study is the assessment and discussion of a model for hand-written Arabic through segmentation. The framework is proposed based on three steps: pre-processing, segmentation, and evaluation. In the pre-processing step, morphological operators are applied for Connecting Gaps (CGs) in written words. Gaps happen when pen lifting-off during writing, scanning documents, or while converting images to binary type. In the segmentation step, first removed the small diacritics then bounded a connected component to segment offline words. Huge data was utilized in the proposed model for applying a variety of handwriting styles so that to be more compatible with real-life applications. Consequently, on the automatic evaluation stage, selected randomly 1,131 images from the IESK-ArDB database, and then segmented into sub-words. After small gaps been connected, the model performance evaluation had been reached 88% against the standard ground truth of the database. The proposed model achieved the highest accuracy when compared with the related works.
Facial Age Estimation using Transfer Learning and Bayesian Optimization based on Gender Information
Authors: Ahmed Marwa , Viriri Serestina
Published: January 2021

Age estimation of unrestricted imaging circumstances has attracted an augmented recognition as it is appropriate in several real-world applications such as surveillance, face recognition, age synthesis, access control, and electronic customer relationship management. Current deep learning-based methods have displayed encouraging performance in age estimation field. Males and Females have a variable type of appearance aging pattern; this results in age differently. This fact leads to assuming that using gender information may improve the age estimator performance. We have proposed a novel model based on Gender Classification. A Convolutional Neural Network (CNN) is used to get Gender Information, then Bayesian Optimization is applied to this pre-trained CNN when fine-tuned for age estimation task. Bayesian Optimization reduces the classification error on the validation set for the pre-trained model. Extensive experiments are done to assess our proposed model on two data sets: FERET and FG-NET. The experiments’ result indicates that using a pre-trained CNN containing Gender Information with Bayesian Optimization outperforms the state of the arts on FERET and FG-NET data sets with a Mean Absolute Error (MAE) of 1.2 and 2.67 respectively.
