Objective: During the physical therapy education, if we can understand the student’s attitude then we can make valuable suggestions with respect to the teaching in the universities and professional employment in the country. The aim of the current study is to develop a questionnaire to test the physical therapy students attitudes towards their education and profession and to test its test-retest reliability and content validity. Design: Cross-sectional study. Methods: A total of 47 physical therapy students who were in their final year were randomly selected to participate in the study. After the making of the questionnaire, it was given to 6 professional experts teaching in the field of physical therapy to obtain their responses for each question with a 5-point Likert scale grading. Their answers were used in making the content validity of the questionnaire. Afterwards, the physical therapy students were asked to fill the questionnaire. Instrument reliability and test-retest reliability were also assessed by having the students complete the questionnaire after one month of taking the questionnaire. Results: The content validity index was 0.71 for the whole scale and values of individual subdivisions were ranging from 0.69 to 0.75. Instrument reliability measured by Cronbach’s alpha coefficient was 0.86 for the whole scale and subdivision values were ranging from 0.32 to 0.86. Test-retest reliability was assessed by intraclass correlation coefficient, which was 0.71 for whole scales and subdivision values were ranging from 0.38 to 0.70. Conclusions: This questionnaire, which assesses the physical therapy student attitude towards their education and profession, has good content validity, instrument reliability, and test-retest reliability.

Chickpea (Cicer arietinum L.) is a major food legume crops for the tropics and sub-tropical regions and is the main dietary protein source for vegetarians in developing countries. Besides several abiotic factors, its production is constrained by insect pests, as well as many fungal diseases. The success of any attempt to produce resistant varieties through genetic engineering to a large extent depends on the availability of efficient and reproducible regeneration and transformation procedures. Further, the transformation techniques can be more successfully applied if the ontogeny of shoot development is well understood. Ontogeny of shoot development from axillary meristem explants (AME) in chickpea has been studied with the optimization of conditions for high-frequency multiple shoot induction. Preculture of seeds in TDZ significantly enhances the frequency of multiple shoot induction from the explants. Ontogeny and early events of multiple shoot induction revealed direct adventitious origin of the shoots. The understanding of the regeneration process could be further utilized in the designing of efficient transformation methods.

Bionanotechnology has revolutionized nanomaterial synthesis by providing a green synthetic platform using biological systems. Among such biological systems, microalgae have tremendous potential to take up metal ions and produce nanoparticles by a detoxification process. The present study explores the intracellular and extracellular biogenic syntheses of silver nanoparticles (SNPs) using the unicellular green microalga Scenedesmus sp. Biosynthesized SNPs were characterized by AAS, UV-Vis spectroscopy, TEM, XRD, FTIR, DLS, and TGA studies and finally checked for antibacterial activity. Intracellular nanoparticle biosynthesis was initiated by a high rate of Ag+ ion accumulation in the microalgal biomass and subsequent formation of spherical crystalline SNPs (average size, 15-20 nm) due to the biochemical reduction of Ag+ ions. The synthesized nanoparticles were intracellular, as confirmed by the UV-Vis spectra of the outside medium. Furthermore, extracellular synthesis using boiled extract showed the formation of well scattered, highly stable, spherical SNPs with an average size of 5-10 nm. The size and morphology of the nanoparticles were confirmed by TEM. The crystalline nature of the SNPs was evident from the diffraction peaks of XRD and bright circular ring pattern of SAED. FTIR and UV-Vis spectra showed that biomolecules, proteins and peptides, are mainly responsible for the formation and stabilization of SNPs. Furthermore, the synthesized nanoparticles exhibited high antimicrobial activity against pathogenic gram-negative and gram-positive bacteria. Use of such a microalgal system provides a simple, cost-effective alternative template for the biosynthesis of nanomaterials in a large-scale system that could be of great use in biomedical applications.
A novel framework to improve the performance of crowdfunding platforms
Jaya Gera,Harmeet Kaur 한국통신학회 2018 ICT Express Vol.4 No.2
This work presents a framework for evaluating and promoting campaigns that are launched over a crowdfunding platform. Campaigns are evaluated on the basis of campaign features and pledge performance. To promote a campaign, a recommender model is designed that filters campaigns to be promoted using association rule mining and based on backer’s interests. Framework also assesses creators’ using their past records and their profile text. This system deals with the issues faced by three stakeholders of crowdfunding and strives to satisfy their requirements and maximizes the utility of tool.
One-pot Lignocellulosic Biomass Conversion into Value-Added Chemicals
( Jaya Gladys Tiffany ),김재훈 한국공업화학회 2019 한국공업화학회 연구논문 초록집 Vol.2019 No.0
Lignocellulosic biomass is an abundant renewable resource and most importantly has enormous potential to be converted into various value-added chemicals for future biorefinery application. However, selective conversion of woody biomass is extremely challenging due to its complex structure. Herein, we investigated bimetallic Cu-Ru/HZSM5 catalyst for one-pot lignocellulose conversion in aqueous environment. HZSM5 provides acid sites required for consecutive depolymerization of holocellulose, dehydration, and isomerization while Cu-Ru synergistically promote hydro-genation/genolysis. Direct conversion of lignocellulose yielded up to 24.2wt% of lignin-derived monomers, cyclopentanone and methyl-cyclopentanone at 300 °C under pressurized H2 (3MPa) for 1h. This one-pot process can be a very promising and energy-efficient approach for utilization of whole lignocellulose into versatile platform chemicals in pharmaceuticals, fragrance, and polymer industries.
