Statistical Evaluation of Item Nonresponse Methods Using the World Bank’s 2015 Philippines Enterprise Survey
Authors: Et.al Madeline D. Cabauatan 
Published: April 2021

The main objective of the study was to evaluate item nonresponse procedures through a simulation study of different nonresponse levels or missing rates. A simulation study was used to explore how each of the response rates performs under a variety of circumstances. It also investigated the performance of procedures suggested for item nonresponse under various conditions and variable trends. The imputation methods considered were the cell mean imputation, random hotdeck, nearest neighbor, and simple regression. These variables are some of the major indicators for measuring productive labor and decent work in the country. For the purpose of this study, the researcher is interested in evaluating methods for imputing missing data for the number of workers and total cost of labor per establishment from the World Bank’s 2015 Enterprise Survey for the Philippines.
The performances of the imputation techniques for item nonresponse were evaluated in terms of bias and coefficient of variation for accuracy and precision. Based on the results, the cell-mean imputation was seen to be most appropriate for imputing missing values for the total number of workers and total cost of labor per establishment. Since the study was limited to the variables cited, it is recommended to explore other labor indicators. Moreover, exploring choice of other clustering groups is highly recommended as clustering groups have great effect in the resulting estimates of imputation estimation. It is also recommended to explore other imputation techniques like multiple regression and other parametric models for nonresponse such as the Bayes estimation method. For regression based imputation, since the study is limited only in using the cluster groupings estimation, it is highly recommended to use other possible variables that might be related to the variable of interest to verify the results of this study.

Morphological Transformation In Poor Lighting Images For Image Contrast Enhancement
Authors: Et. al. Gutta Srinivas Rao, 
Published: April 2021

The paper presents a novel algorithm for the computation of the image decomposition using a morphological filter with reconstruction. The target applications are image contrast enhancement especially those with high dynamic content. Both bright and dark regions contrast enhancement were considered. A new hardware efficient implementation of decomposition is presented. Following decomposition in 5 levels of detail a local contrast enhancement is performed. The new reconstruction algorithm and its hardware implementation as proposed is shown to be independent on structural element size and that it results in a predictable time frame operation. A mixed schematic and VHDL/Verilog description of the decomposition filters was synthesized and results show far higher speed performance compared with solutions found in recent literature.
Image organizing strategies are essentially required to the pictures captured by satellites. The grey levels in the image captured by satellites need to be normalized for improving picture contrast. The pictures captured by satellites are generally poor in quality and the contrast levels are also very less. In this manuscript a differentiation approach dependent on scientific morphology called rotational morphological transformations are proposed using Modified Opening by Reconstruction Method (MORM). This methodology upgrade pictures with poor contrast and unable to recognize the objects in the image. In the images with poor lightening, morphological operations are performed to improve its clarity and contrast. Picture enhancement has been done by applying morphological operations on the satellite images considered. The technique utilizes data from picture by squares, while the morphological methods change the strategy using the contrast enhancement activity, which is utilized to characterize the multi-foundation poor lightening pictures. The total picture handling procedure is implemented utilizing MATLAB reproduction model. The MORM method is compared with the traditional methods and the results show that the proposed method is better in improving the accuracy rate.

Authors: Khalilova Aysel Zahid 
Published: April 2021

The goals of distance education in higher institutions were clear for many years. Nowadays, owing to the global pandemic situation, higher educational institutions (HEI) have had to transition from conventional teaching modes to online modes. Although many top-ranked universities were prepared for this situation, others suffered, since their distance education department existed only in name; their activities were passive. However, COVID-19 provided an opportunity for them to think deeply about their next steps.
In general, distance learning is an effective way of attracting adult learners. Furthermore, these learners desire a higher level of flexibility.
This article is based on the theoretical models essential to long-term plausibility and viability in the field of teaching practice. To evaluate the challenges and problems arising during online learning, the author has briefly reviewed all the contributions made to this field in the 21st century.
In addition, the paper suggests tools and facilities for teachers and instructors in order to facilitate effective communication between teachers and students, both in and out of the virtual classroom. Researchers, post-graduate students and other readers will be able to use this paper to explore and exploit further modifications of research opportunities in this field.
The Use of Functional Opportunities of Virtual Folklore in Lifelong Learning and Its Psychological Aspects
Authors: Hikmet Guliyev Serkhan Khaveri, Sefa Garayev, 
Published: April 2021

One of the most important conditions for the education to be targeted to the requirements of modern times, as well as to be suitable for social orders, is determining the effective training technologies. Many socio-cultural institutions, including the training models of the traditional-cultural institutions and the traditional models of knowledge transfer can be urgent and effective in determining the effective learning technologies. In this sense, folklore has a great potential of use in the application of modern educational technologies with its own functional capabilities that played an important role during many centuries in the interaction of some individuals with one another, in the socialization of people and in the self-formation of society. It is known that in the traditional-cultural environment there were institutional aspects and structures of knowledge transfer. Before the appearance of the written language in the oral communication level the information, i.e. the gained experience and knowledge were passed with the empiric models from generation to generation by old people, wise elders who were the institutional aspects of the traditional culture.
The training technologies of the traditional culture have the following peculiarities:

Unlike the religious training technologies, it is not dogmatic, it has a democratic nature.
Taking into consideration the vital situations it has an operative adaptation character.
It has a character of getting and transferring the knowledge empirically.
It has the ability of taking into consideration the individual abilities and character in the process of incessant learning and teaching.

The appearance of the Internet which is considered the “apogee” of communication has caused the formation of new transformations of traditional folk culture, virtual folklore samples as in all other spheres. Of course, in modern times at the stage when the digital resources are growing, the methods and means of getting, transferring and mastering knowledge, as a whole, the formation of education has completely changed. That is why, we consider that it is possible to use the opportunities of folklore the potential of virtual folklore and digital folklore resources, in the of lifelong education and innovative educational concepts, in getting and teaching of knowledge. Because the folklore resources have unique opportunities in formation of socio-psychological essence of personality. There is a great need for the individual to adopt the folklore of this group to freely enter and become a member of various social groups without experiencing psychological complex and tension in all spheres of society. In this sense, one of the goals of modern education is to aim the growing new generations to promote stereotypes that are in harmony with human values and to free them from non-humanist and local stereotypes.

Several studies have shown that medical students experience high levels of stress during their undergraduate course, due to the medical curriculum. Due to COVID shut down, now students are away from regular college routine, but are they still stressed?This study was conducted to better understand student’s experiences of stress, for instance, what causes students stress and what students do to manage their feelings of stress. First year medical students from various medical colleges in Karnataka were selected for the study. Questionnaire related to symptoms of stress and coping methods, Grading the reason of stress and needed guidance were included. Questions were circulated online. 115 responses were recorded and analyzed. This study showed in the past three months during the shutdown, 63 percent of students were feeling low, 60 percent students said they are feeling anxious. 60 percent felt irritable. 30-50 percent students are completely stressed of missing on regular classes, practical and clinical exposure, uncertainty of exams and uncertain future. More than 5 percent students are sorting medical help for the same. More than 90 percent of students who are stressed are trying many relaxation methods. None of the students have opted for any college faculty or councilors for help during this crisis.More than 50 percent medical students are stressed and are having symptoms None of them have opted for guidance or counselling from the colleges. From this study, I conclude that all colleges must provide college councilors or staff to help students deal with their stress during such crisis. On a regular basis, student must be made aware of counsellors or mentors in college or attached hospital, whom they can consult when needed.

Authors: Rajan Merlin Leena 
Published: April 2021

The Circle of Willis is an arterial anastomosis uniting the internal carotid artery with the vertebro-basilar system. This cerebral arterial circle has ten components namely- the two anterior cerebral arteries, branches of internal carotid arteries, connected by the anterior communicating artery anteriorly, and the two posterior cerebral arteries, branches of basilar artery, connected to the internal carotid arteries via the two posterior communicating arteries. The aim of this study was to study the variations in the formation of the posterior part of the circle of Willis using Magnetic Resonance Angiography (MRA), and to review the embryological and clinical perspectives. The study was conducted over 18 months in the Department of Anatomy in collaboration with the Department of Radio-diagnosis at Pushpagiri Institute of Medical Sciences and Research Centre, Tiruvalla. MRA study was performed on 215 images, which were obtained from the electronic database at the Department of Radio-diagnosis. All the circles were further subdivided into complete and incomplete, both as a whole, and pertaining to the posterior parts, and analyzed. In this study, it was observed that the entire circle was complete in approximately 62-66% of the total, the posterior part being complete in approximately 66-76% of the total. The incidences of variations were observed to be higher on the right side than on the left. The most frequent variation was the partial foetal variant of posterior cerebral artery (PCA) in the posterior part of the circle of Willis.

Published: April 2021

Spleen is the largest haemo-lymphoid organ located in the left hypochondrium and partly in the epigastrium between the fundus of the stomach and the diaphragm. The size and weight of the spleen varies with age and gender. In adults it is usually 12 cms in length, 7 cms broad and 3-4 cms in thickness. It weighs around 150gms. On the superior border, near the anterior end, there may be one or two notches, persisting from the lobulated form of the spleen in early foetal life.Spleen acts as a filter for blood, storage of lymphocytes and platelets. Old red blood cells are recycled in the spleen. It metabolizes the haemoglobin removed from old senescent RBCs. The knowledge of morphometric variations of spleen helps clinicians, radiologist and surgeons to differentiate it from the various splenic injuries and pathologies.The aim of the study is to find the morphometric variations of spleen.The present study was done on 50 adult human spleens of unknown sex. The morphometric features like shape, presence of notches, length, breadth and thickness were noted.Out of 50 spleens studied, five different shapes of the spleen were observed. 19 spleens were wedge shaped (38%), 12 spleens were triangular shaped (24%), 9 spleens were tetrahedral (18%), 5 spleens were oval shaped (10%), 5 spleens were irregular shaped (10%). 31 spleens (62%) had notches on its superior border, 2 spleens (4%) had notches on its inferior border, 12 spleens (24%) had notches both in their superior and inferior borders, 5 spleens (10%) were found with absence of notch on either of its borders. The presences of splenic fissure on diaphragmatic surface were noted in 2 spleens. The length of the spleen varied between 7cms to 15cms, the breadth of the spleens varied between 4cms to 12cms and the thickness of the spleens varied between 2cms to 6cms.The knowledge of morphometric features of the spleen is of great importance to the clinicians, radiologists and surgeons for their surgical procedure.
