An Application of Interval-Valued Fuzzy Soft Sets in Medical Diagnosis

Abstract The concept of soft set is one of the recent topics developed for dealing with the uncertainties present in most of our real life situations. The parametrization tool of soft set theory enhance the flexibility of its applications. In this paper we extend Sanchez's approach for medical diagnosis using interval-valued fuzzy soft sets and exhibit the technique with a hypothetical case study

Decision making under incompleteness based on soft set theory

[EN]Decision making with complete and accurate information is ideal but infrequent. Unfortunately, in most cases the available infor- mation is vague, imprecise, uncertain or unknown. The theory of soft sets provides an appropriate framework for decision making that may be used to deal with uncertain decisions. The aim of this paper is to propose and analyze an effective algorithm for multiple attribute decision-making based on soft set theory in an incomplete information environment, when the distribution of incomplete data is unknown. This procedure provides an accurate solution through a combinatorial study of possible cases in the unknown data. Our theoretical development is complemented by practical examples that show the feasibility and implementability of this algorithm. Moreover, we review recent research on decision making from the standpoint of the theory of soft sets under incomplete information

ANTIOXIDANT, ANTIBACTERIAL AND HEPATOPROTECTIVE ACTIVITIES OF CISSUS REPENDA VAHL ON CARBON TETRACHLORIDE (CCL4) INDUCED LIVER DAMAGE IN BIRD COLUMBA LIVIA

Objectives: Drug induced liver damage has been identified as one of the major global diseases in recent years. The plant derived alternative medicines are considered as the most effective solution for combating such liver diseases. In the present study, the antioxidant, antibacterial and hepatoprotective property of Cissus rependa Vahl. was evaluated. Methods: Anti-oxidant activity of the extracts were spectrophotometrically determined using ascorbic acid as standard. Determination of antimicrobial activity followed by Agar well diffusion method and nutrient content by standard laboratory methods. The activity of the two enzymes were measured spectrophotometrically (520 nm) following the DNPH method with minor modification   Results: The study shows that the aqueous extract of the plant leaf contains a good number of phytochemicals such as cardiac glycoside, saponin, alkaloid etc. as well as antioxidant with respect to the scavenging activity against free radicals DPPH (79.79 %) and ABTS (84.6%) which were roughly comparable to that of ascorbic acid (88.2% and 83.0 % respectively). The plant extract also exhibited potent antibacterial activity against S. aureus and P. vulgaris indicating its bactericidal or bacteriostatic properties. The study also indicates that the oral feeding of aqueous extract of the plant could reduce the CCl4 induced chronic damage of hepatic tissue in bird (C. livia) which was reflected by the decreased level of total soluble protein as well as activity of the enzymes Aspertate aminotransferase (AST) and Alanin aminotransferase (ALT) in both liver and muscle tissues of EX (experimental) group treated with plant extract as compared to that of untreated birds PC (positive control) group which otherwise had highly increased due to CCl4 induced tissue damages. Key words: Antioxidants, Cissus rependa Vahl, hepatotoxicity, Aspertate aminotransferas and phytochemicals

The Impact of COVID–19 on ESL Learning in India: Problems, Challenges, and Coping Strategies

COVID-19 has significantly affected the teaching-learning continuum in India. Most of the educational institutes had adopted online mode for the delivery of content and pedagogies enabled by digital technology, devices, and platforms. The pandemic has adversely affected English language learning in India, for learners used to learning ESL in a real-life situation through regular face-to-face mode experienced challenges in earning ESL through virtual mode. Learning English to develop the required language skills in virtual classrooms was anything but easy. Nonetheless, Indian students, as this study finds, took up the challenge by their stride and survived the altered learning conditions forced by the pandemic. This student-centric study aims to explore the impact of COVID-19 on language learning, the problems and challenges faced by student-learners, and the strategies to overcome them. An online survey was conducted to collect data from a group of students (n=400) using a survey questionnaire and mixed methods were used for data analysis and interpretation. The results indicate that the students experienced moderate to high-level difficulty in language learning and their coping strategies worked out
