In this study, HAP-gelatin and CC-gelatin nanocomposite scaffolds, as bioactive inorganic materials, were synthesized successfully through a chemical precipitation procedure. Next, characterization of the prepared nanocomposite scaffolds was completed using scanning electron microscopy (SEM), dynamic light scattering (DLS), zeta-sizer (for zeta potential measurement), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). Then, we soaked the generated nanocomposite scaffolds in the simulated body fluid (SBF) for several times to investigate and compare the bioactivity of these nanocomposites and determine the percent of weight loss. The rate of calcium ions dissolution in SBF media was determined utilizing atomic absorption spectroscopy (AAS). The findings of characterization showed that the preparation of nanocomposites was successful with monodispersed nanosized particles, uniform agglomerated morphology, crystalline form, and negative surface charge. According to the results of the bioactivity test, both nanocomposite scaffolds were of high bioactivity, corroborated well with the patterns of calcium release. Calcium ions released from the HAP-gelatin nanocomposite were higher than that of the CC-gelatin. However, the bioactivity of CC was comparable with well-known bioactive HAP material. Therefore, it could be a promising alternative for use compared with HAP, the preparation of which is more complicated and expensive.

Covid-19 has had adverse impact on various sectors of the economy. India’s Corona epidemic started spreading at the fastest pace across the world, becoming the 3rd highest country with infected corona patients. If no further vaccines or measures are in place, it will be very difficult to stabilize the situation. The government is trying to manage the various challenges that are coming in their way through various economic packages and providing extra funds for healthcare sector. During the lockdown the informal sector suffered the maximum due to the job losses and food insecurity. The livelihood sector which includes agricultural, fishing, poultry, self-help groups and migrant workers are major sufferers in India. Unemployment level in India reached all-time high reaching 23.5 % in April after imposing nationwide lockdown to curb the spread of pandemic.

Employees’ engagement or employees’ commitment is the most sought-after skill in employees for yielding maximum productivity at the work front as well as being happy at the personal front. There are many factors that affect engagement levels such as work culture, job satisfaction, remuneration, etc. However, 2020 brought another new factor, i.e. the impact of the Coronavirus pandemic on the lives of people around the globe. This lockdown introduced new modes of work in the form of remote working conditions. Accordingly, Covid19 has had a huge effect on the motivation levels of people and thereby impacted productivity. The objective of this study is to map the impact of this pandemic on the engagement levels of the employees in information technology companies. This research has adopted a descriptive survey method and has used both primary and secondary data to deduce results. The findings of this study can help organizations to adopt new methods to keep their employees committed towards their work during periods of crisis such as Cornona pandemic.
