Ability and ambition are not enough for success. Success of

any project depends solely on support, guidance and encouragement received from

guide, our parents and well wishers. I have been fortunate to have more than one

pillar of strength in my humble effort to make this research successful.

Gratitude is probably hardest emotion to express and often

one does not find adequate words to convey the entire feelings. I am pleased to

express my deep sense of gratitude to my guide Dr.Aruna Palta who has opened

flood gates of her knowledge for me and her extending continuous cooperation and

encouragement. Without her supervision, superb guidance, constructive

suggestions and sympathetic attitude, the present study would not have able to see

the light of this day. It is my fortune to have availed the opportunity of working

under her guidance.

Always standing by me and helping to every extent was my

co supervisor Dr.Vasu Verma. I convey my grateful thanks to her. I express my

sincere thanks to Dr.Gaurav Thukral, Facility Director, Raigarh, Fortis group of

Hospitals and Dr.Arvind Dayal, Head of Medical Services, Fortis O.P. Jindal

Hospital & Research Center, Raigarh for their kind support and permission to

carry out this study . I am highly indebted to all the plant employees who

cooperated me in the entire course of my study.

Not to be forgotten are all the teaching and non teaching staff

of my research center Govt. D. B. Girls P.G. College, as I was to able to complete

my work successfully with their support and cooperation. A word of appreciation

goes to Shri Maneesh Dandekar for statistical analysis.
