Teachers’ Exploration of Data Science Subject: For the Evaluation of Students’ Academic Performance

The paper focuses on the need for knowledge of Computer Science, Statistics, and Data Science for English teachers in particular and other subject teachers at large. Academic teachers are good at expressing in English both written and spoken. But in the situations of numerical comparisons like which numerical number of the student is the outlier in the class, are grey areas for them. Hence this paper helps teachers to get an awareness of incorporating the concepts of Google Collab, statistics, and how to do comparative study using central tendency in Data Science in their English/other subjects classroom

Approaches in biotechnological applications of natural polymers

Natural polymers, such as gums and mucilage, are biocompatible, cheap, easily available and non-toxic materials of native origin. These polymers are increasingly preferred over synthetic materials for industrial applications due to their intrinsic properties, as well as they are considered alternative sources of raw materials since they present characteristics of sustainability, biodegradability and biosafety. As definition, gums and mucilages are polysaccharides or complex carbohydrates consisting of one or more monosaccharides or their derivatives linked in bewildering variety of linkages and structures. Natural gums are considered polysaccharides naturally occurring in varieties of plant seeds and exudates, tree or shrub exudates, seaweed extracts, fungi, bacteria, and animal sources. Water-soluble gums, also known as hydrocolloids, are considered exudates and are pathological products; therefore, they do not form a part of cell wall. On the other hand, mucilages are part of cell and physiological products. It is important to highlight that gums represent the largest amounts of polymer materials derived from plants. Gums have enormously large and broad applications in both food and non-food industries, being commonly used as thickening, binding, emulsifying, suspending, stabilizing agents and matrices for drug release in pharmaceutical and cosmetic industries. In the food industry, their gelling properties and the ability to mold edible films and coatings are extensively studied. The use of gums depends on the intrinsic properties that they provide, often at costs below those of synthetic polymers. For upgrading the value of gums, they are being processed into various forms, including the most recent nanomaterials, for various biotechnological applications. Thus, the main natural polymers including galactomannans, cellulose, chitin, agar, carrageenan, alginate, cashew gum, pectin and starch, in addition to the current researches about them are reviewed in this article.. }To the Conselho Nacional de Desenvolvimento Cientfíico e Tecnológico (CNPq) for fellowships (LCBBC and MGCC) and the Coordenação de Aperfeiçoamento de Pessoal de Nvíel Superior (CAPES) (PBSA).

Electrospinning of hydrogels for biomedical applications

The field of biomedical applications for hydrogels requires the development of nanostructures with specific controlled diameter and mechanical properties. Nanofibers are ideally candidates for these advanced requirements, and one of the easiest techniques that can produce one-dimensional nanostructured materials in fibrous form is the electrospinning. This technique provides extremely thin fibres with controlled diameter, highly porous microstructure with interconnected pores; extremely versatile allowing the use of various polymers for tailoring various applications requirements and it is a simple cost-effective method on preparation of scaffolds. In this section, we will discuss recent and specific applications with a focus on their mechanisms. As such, we conclude this section with a discussion on perspectives and future possibilities on this field.ye

Smart Manufacturing through TOC based Efficiency Monitoring System (TBEMS)

The very purpose of business is to devise profitability and enhance it in all possible avenues sustainable. In a manufacturing environment, thus, there had been a number of techniques and concepts adapted to improvise the effectiveness thereby profits continuously. Theory of Constraints (TOC) adopts a unique con-cept exploiting the constraint to deliver the customer needs. TOC is built on the premise that the weakest link determines the strength of the whole chain. With the advent of Industry 4.0, the manufacturing systems could be exploited to the next best level, leveraging the interaction of cyber physical systems and human beings over the internet. This paper deals with a novel idea of implementing TOC concept blended with Internet of Things (IoT), thereby, the speed of implementation could be augmented for early results. Evidently, the smartness of Things is    derived based on the possibility of informed and proactive decisions.  Hence all the productivity improvement techniques and concepts could be complemented with such concurrent information and analytics, thereby the learning and decisions are much smarter and proactive. A real time industrial environment has been chosen to experiment this approach and the results are furnished paving way for future research and improvisation globally on the industrial environment and on many other competing productivity concepts  </jats:p

EFFECTIVENESS OF MUSIC PLAYBACK ON INTRAVENOUS CANNULATION PAIN AMONG CHILDREN

A quasi experimental study was conducted to assess the effectiveness of music playback on intravenous cannulation pain among children in a selected hospital. Objectives: to assess the mean posttest pain score among children in the experimental and control group, to find out the effectiveness of music playback on intravenous cannulation pain among children and to find out the association between posttest pain score and selected socio demo graphic variables of children in control group. Quasi experimental posttest only controls group design and convenience sampling technique was used to select 60 children in a selected hospital at Alappuzha district. Conceptual framework: Ernestine Wiedenbach’s Helping Art of Clinical Nursing Theory (1969). Posttest was conducted in the control and the experimental group by using FLACC Behavioral Pain Scale and Socio demographic proforma. Music playback was played to the experimental group for 10 minutes during intravenous cannulation. The data were tabulated and analysed using descriptive and inferential statistics. The mean posttest pain score of children in the experimental group was 4.1 with SD 1.33 which was significantly lower than the mean posttest pain score of children in the control group which was 7.8 with SD 1.27 with a mean difference of 3.6. The calculated ‘t’ value 10.910 was greater than the table value 2.00, is significant at p&lt;0.05 level with degree of freedom 58. Hence, we can conclude that the music playback was effective in reducing the pain level of children during intravenous cannulation. The analysis showed that the calculated chi square value for family monthly income, number of previous hospitalisations, previous exposure of cannulation were greater than that of the table value at p &lt; 0.05 level of significance. Hence null hypothesis (H02) can be rejected and research hypothesis (H2) can be accepted. So, it can be concluded that there was significant association between posttest pain score an</jats:p
