Quality of services rendered to the patients is of vital importance in the whole process of health-care. On account of large population of the country, poor per capita income, inadequate ratio of number of patients to the number of doctors as well as poor medical infrastructure the quality is quiet poor and needs urgent attention on the part of planners and executers of health-care systems in the country. In the wake of above it was decided to have a preliminary critical look at the current health-care system. The overall volume being very large it was decided to focus on small segment using Statistical Process Control as a tool of study. A case study of the hospital was taken to implement Statistical Process Control tools. This study involves a look into two areas, namely: -occurrence of post surgical wound infection in the general surgery department and the time spent by patients at various stages of health-care process in outpatient department (O.P.D), to bring out the lapses and suggest suitable remedial measures. For the purpose two case studies have been conducted and results presented thereof. This study reveals serious gaps consequently considering the scope of improvement.
Grinding is most widely used machining process as it provides reasonable material removal rate along with desirable surface quality especially for hard and high strength materials. Present work studies the interaction of Tangential force and Specific Energy with different process parameters such as wheel speed, table speed, grit size and depth of cut. Grinding is high specific energy process and specific grinding energy is one crucial performance parameter of grinding. Primary energy components such as shearing due to chip formation, rubbing and ploughing are the major contributors to the total specific energy consumption in grinding. High specific energy eventually causes higher material removal cost.New and innovative method of single grit experiment is used to develop theoretical model of specific ploughing. Ploughing energy was found to be significant during low depth of cut. Exponential rise in specific ploughing energy during low depth of cut explains the "size effect" phenomenon in grinding. This has enhanced the knowledge of ploughing phenomena with respect to process parameters and material properties of the workpiece.
