Global competitive pressures are asking industrial companies to find the best way to meet their customer's requirements, reduce the costs of products, and increase productivity. Quality improvement has been proposed and implemented as a primary means of achieving these purposes. The quality improvement usually includes a goal of reducing the costs due to poor quality. While these costs of poor quality (COPQ) are not known precisely, they are known to be very high. Also, they may be underestimated by the hidden costs due to non-value activities, such as potential lost sales, costs of redesign due to quality reasons, and extra manufacturing costs due to defects, etc. In any manufacturing or service operation, all actions and resource expenditures of a company should be focused on creating value for customers. Any activity or resource of not creating the value for customers could be regarded as waste, which consequently causes the COPQ. Some companies did use dashboards to understand and identify value added or non-value added activities in order to reduce or eliminate wastes. These dashboards must be properly designed to consider inherent differences in manufacturing or service operations among business organizations. In addition, a structured quality improvement program such as the Six Sigma must support these dashboards. In this paper, a case study of designing dashboards for evaluating and reporting the COPQ in business units is presented.

Fruit-specific promoters play an important role in the improvement of traits, such as fruit quality through genetic engineering. In tomato, the development of fruit-specific promoters was previously reported, but less attention has been paid to the promoters involved in the fruit development stage. In this study, we characterized the gene expression patterns of tomato alcohol dehydrogenase 2 (SlAdh2) in various tissues of wild-type tomato (cv. Ailsa Craig). Our findings revealed that SlAdh2 expression levels were higher in the developing fruit than in the leaves, stems, and flowers. The ProSlAdh2 region, which is expressed at different stages of fruit development, was isolated from tomato genomic DNA. Following this, it was fused with a β-glucuronidase reporter gene (GUS) and introduced into wild-type tomato using Agrobacterium-mediated transformation to evaluate promoter activity in the various tissues of transgenic tomato. The ProSlAdh2:GUS promoter exhibited strong activity in the fruit and weak activity in the stems, but displayed undetectable activity in the leaves and flowers. Interestingly, the promoter was active from the appearance of the green fruit (1 cm in size) to the well-ripened stage in transgenic tomatoes, indicating its suitability for transgene expression during fruit development and ripening. Thus, our findings suggest that ProSlAdh2 may serve as a potential fruit-specific promoter for genetic-based improvement of tomato fruit quality.

The purpose of this study was to investigate the quality characteristics and antioxidant activity by collecting four times on six samples of Jeonbuk regional soybean pastes (Doenjang) traditionally prepared for this study. The water content of samples decreased according to progress of the aging period and the water content of the fourth sample collected was 42.40~59.64% (p<0.05). The salinity of the fourth Doenjang samples was 11.80~18.60%. The amino-type nitrogen content was 122.67~540.33 mg% immediately after the preparation of Doenjang in the Jeonbuk region and the content of the fourth collection samples increased from 251.49 to 982.36 mg% (p<0.05). The isoflavone glycosides decreased but daidzein, genistein and glycitein, which are aglycones, increased during aging periods. The total polyphenol content of the fourth collected samples was 11.99~19.27 mg GAE/g (p<0.05). The DPPH radical scavenging activity, ABTS radical scavenging activity and FARP of the fourth Doenjang samples were 51.88~81.21%, 84.14~90.32%, and 1.08~3.11 mg Trolox/g, respectively. As a result of quality analysis on Doenjang, the superiority of traditional Doenjang has been proven by the increase of amino nitrogen content and antioxidant activity according to the aging period. However, factor analysis on quality differences of regional Doenjang should be conducted to ensure standardization and quality improvement.

Purpose: The purpose of this study was to determine the effect of simulation evacuation training improvement activity through wheelchair skill training. Methods: The study included 40 patients with early stroke who were randomly allocated to a wheelchair skill training group (Experimental group, n=20) and a general exercise group (Control group, n=20). Both groups performed the exercise 3 times a week for 3 weeks. Outcomes were assessed using Wheelchair Skills Test Skills Performance (WSTSP), Wheelchair Skills Test Skills Safety (WSTSS) and Wheelchair Propulsion Velocity (WPV). Results: After 3 weeks of training, both groups showed significantly improved WSTSP, WSTSS and WPV (p<.01 in both groups). However, the WSTSP, WSTSS and WPV in the experimental group were very significantly better than in the control group (p<.01). Conclusion: These findings indicate that wheelchair skill training may be effective at improving wheelchair skill ability and wheelchair propulsion velocity in stroke patients who cannot walk independently. Therefore, short-term wheelchair skill training could be useful for patient safety in simulated evacuation situations.

The purpose of this study was to assess needs for housing improvement of children group homes in Cheongju-si through interviews with the group home directors and staffs. From April 6, 2018, to April 25, 2018, a series of face-to-face interviews with four directors and three staffs working in four children group homes was conducted. The results were analyzed using thematic analysis technique. Highlights of major findings and implications were as follow: (1) Bedroom: Needs for independent bedrooms and desks for each child were dominant. (2) Common activity space: Interviewees showed somewhat different opinions on common activity spaces according to group home types and/or between directors and staffs. (3) Between "a big and good-quality house" and "a house in good location", interviewees were found to prefer "a big and good-quality house" in order for children to have enough space to run and play. (4) Interviewees insisted that to provide proper group home services and protection similar to a real family, current policy to accommodate up to eight children in one group home should be improved.
