It is very important to understand and interpret the meaning of the sigma level correctly through the Six Sigma project. Especially, the confusion over the relation between sigma level from the short-term point of view and defective proportion or DPMO from the long-term point of view may make a big gap between expected results of the Six Sigma project and real results in the field. The one-tail approximation is commonly used to calculate the sigma level both in most literatures introducing Six Sigma and actual cases of the Six Sigma project. Since the one-tail approximation undervalues the sigma level of the fields such as business and service of which the sigma level is generally low, however. there can be misleading results of the explanation of the sigma level and inappropriate project evaluation. This paper describes the relation between sigma level and defective proportion in detail and clears the difference between the one-tail and two-tail approximation.

Mechanical stress and the vacuum level are the two main factors dominating the quality factor of a resonator operated in the vacuum range 1 mTorr to 10 Torr. This means that if the quality factor of a resonator is very insensitive to the mechanical stress in the vacuum range, it is sensitive to mainly the ambient vacuum level. In this paper, a wafer-level packaged MEMS resonator with a highly vacuum-sensitive quality factor is presented. The proposed device is characterized by a package with out-of-plane symmetry and a suspending structure with only a single anchor. Out-of-plane symmetry helps prevent deformation of the packaged device due to thermal mismatch, and a single-clamped structure facilitates constraint-free displacement. As a result, the proposed device is very insensitive to mechanical stress and is sensitive to mainly the ambient vacuum level. The average quality factors of the devices packaged under pressures of 50, 100, and 200 mTorr were 4987, 3415, and 2127, respectively. The results demonstrated the high controllability of the quality factor by vacuum adjustment. The mechanical robustness of the quality factor was confirmed by comparing the quality factors before and after high-temperature storage. Furthermore, through more than 50 days of monitoring, the stability of the quality factor was also certified.

Purpose: This study aimed to investigate the influence of resilience and symptom experience on quality of life. Methods: Seventy five patients in an active treatment stage were recruited from 2 hospitals between October and December 2010. A survey including perceived health status, physical functional status, the symptom experience index, resilience, and the functional assessment of cancer therapy-colorectal (FACT-C) was completed. Results: The level of FACT-C was 86.61 (${\pm}18.91$), which was higher than for patients with colostomy, but lower than for patients in a rehabilitation stage. Participants without physical functional limitations showed higher level of both resilience and quality of life. Participants with bad health status showed a lower level of both resilience and quality of life and higher level of symptom experience. The quality of life was related to the level of resilience (${\beta}$=.373), symptom experience (${\beta}$=-.292), and perceived health status (${\beta}$=-3.961). Conclusion: Proactive nursing approaches to manage symptoms and to improve perceived health status would enhance the quality of life of colorectal cancer patients. Furthermore, various strategies to strengthen the level of resilience should be developed.
