Abstract: The study was made to the C_pm based Process Capability Analysis Chart C_pm (PCAC_pm) to determine the resistance to ultraviolet radiation poor quality building materials and paints of those characteristics. Finally, sort and identify the characteristics of substandard quality improvement district in order of priority. The proposed method in this study not only to further be extended to other paint products, but also for quality management and process control capabilities of the products.

Abstract: 33 species Chinese cabbage sold in local market were seeded and growth on Cd polluted (Cd 0.65-9.0 mg/kg) soil in the old irrigation area, Shenyang, P.R.China. The harvested Chinese cabbages were collected for analysis of Cd content, soluble protein and soluble sugar, respectively. Results showed that the Cd content in edible parts of varieties Chinese cabbage does not exceed, partly exceed and all out of the allowed standard of 0.2 mg/kg fresh weight Cd, as the soil Cd contents were in the range of 0.65-1.8 mg/kg, 1.81-4.17 mg/kg and 4.18 to 5.3 mg/kg. Soil Cd content has a positive correlation with Cd content in the edible part of all varieties of Chinese cabbage. And soluble sugar and soluble protein showed increased trend as soil cd increase. According to above results, we concluded that the products of Chinese cabbage is relatively safety in quality if growth in soil with Cd content from 0.65 to 1.81 mg/kg , and appropriate screening of low Cd uptake species for Chinese cabbage is necessary as soil Cd content was from 1.81-4.17 mg/kg, to insure the safety of agricultural products , and suitable remediation technology should be used as soil Cd content was from 4.18-5.3 an till 9.0 mg/kg, in order to reduce the food-chains transportation risk brought by Cd accumulated in Chinese cabbage.

Abstract: The rapid development of technology has led to the increased embracing of portable consumer electronics, such as mobile phones, digital cameras, and notebook computers. The lens cameras installed in these electronics are indispensable, and the function and quality of lens cameras have gained increasing attention. This study examines the production processes of lens camera products, utilizing the production capacity indicator C_pm to develop an evaluation model. This approach seeks to determine the important product quality characteristic production processes that have a detrimental impact on lens camera product quality. This study then applies a Six Sigma MAIC product quality improvement process to analyze the reasons for poor product quality, utilizing the Taguchi experimental design to examine the optimal production parameters; this study attempts to control production process quality through applying controls to these parameters. Ultimately, this study attempts to utilize Six Sigma MAIC processes to continually improve the quality of lens camera production processes, helping companies to increase the quality of their lens camera products and improve their competitive positions.
