The main purpose of this research is to use “DMAIC” and “DMADV” framework of six sigma to reduce cost of projects, increase yields, improve performance and reduce defects. This study conclude that the sigma level of cement bag production in four production lines is “4.7 DPMO” values of 710 and the possibility of defects per unit of 11 possibilities this situation was handled by using six sigma. Any business or industry run only to satisfy customer and increase their profits, this can be attained as development of quality product..For the ranking of newly established universities the certification of those institutes is very important and also a critical process. For this process we used Lean six sigma approach that can identify the wastes that affect this process.Six sigma can be applied to any work field such as education, power optimization and other types of industries Six sigma “DMAIC” approach is also used for the testing of EDA tools that occurs due to the complex coding or configurations, flows and platforms they support. To improve the process quality of SDLC it’s necessary to remove the defects of system in advance along with thorough valuation of size and it also makes project accordant with real time environment

The objective of study is to find prevalence of temporomandibular joint pain due to stress in undergraduate university students. Methods: Sample of 253 participants were selected by non-probability convenient sampling technique. Then participants were required to sign on consent form first then Fonseca questionnaire, and PSS was given to them. The patients were interviewed, examined, diagnosed, and rated. Results: This study was conducted on 253 undergraduate university students .FQ and PSS questionnaires were given to them.87  males (34.4%) and 166 females (65.6%).37.5% partipants with moderate stress showed severe TMJ pain.5.9% cases were reported with mild pain. The percentage of temporomandibular joint pain is calculated to be 58.1% percent in university students. Conclusion(s): Hence, it has been concluded that stress is a factor that cause TMJ pain in undergraduate university students. This study shows that stress and TMJ pain have direct positive and strong corelation between them. Stress not only cause TMJ pain but it can also increase the severity of the pain. .The percentage of temporomandibular joint pain is calculated to be 58.1% percent in university students. The result concludes that the prevalence of temporomandibular joint pain among students of university is high.
