and other DRDO personnel from DRDO HQrs and
Delhi-based labs, in all and more than 100
personnel took part in the walk. The walk focused on
bringing awareness among the participants on
numerous benefits like managing weight, controlling
blood pressure, decreasing the risk of heart attack,
burning fat and boosting the energy levels. The
walk concluded with distribution of Coco-jal and
variety of Leh-Berry juices produced by private industry under Transfer of Technology (ToT) from DRDO.
In salutation to DRDO on its Golden Jubilee Year, DRDO Sports Board also organised a workshop on Fit Body
Healthy Mind on 25 March 2008. The workshop focused on the importance of fitness in the daily life of the DRDO
employees and to inculcate amongst them habit of being involved with some.
Dr Prahlada, CC R&D (SI) & DS expressed his happiness

development and fullfilling societal needs. Earlier, Dr
Prahlada, DS and CC R&D (SI) expressed that within the
framework of academic freedom, the grants-in-aid
research projects should be designed to derive benefits.
He also emphasised that directed research should form a
significant part of the grants, which support blue-sky
research and applied project-oriented R&D.
The sessions of oral presentations were chaired by Shri N
Sitaram, DS and CC R&D (ECS) and Dr D Banerjee, DS
