The driving force of the manufacturing field is members' mind-set and activity. However, there is no appropriate program of change management for workers who work in the manufacturing field. Most of the small group activities were focused on the fixed tools and processes to make improvement only, not the change itself. Therefore, it was difficult to have self generating energy without actually motivating people of change. Study of IFI(Integrated Field Innovation) means change of management. This study will introduces IFI which is a new methodology of change and innovation of workers, and will describe how workers participated in the activities voluntarily. The principle of IFI is that letting employees to find the problems of the sites -anything that makes employees considering as the problem while they are working- and solve those problems through any tools own their own. Workers do not have to waste their time on bounding by unnecessary tools and processes. There are several cases that company "D" has been actually applied the IFI methodology in 2008. Through these cases, IFI proved that it was a optimized methodology for workers who work in the manufacturing field.

Cynanchi wilfordii Radix roots have been utilized as traditional medicine for variety of diseases including diabetes mellitus, aging progression and scavenging free radicals, enhancing immunity, reducing high serum cholesterol, and anti-tumor activity. However, the mechanisms underlying this effect remain poorly understood. The principal objective of this study was to determine the effect of cynandione A on osteoclast cells. Thus, we was isolated cynandione A from Cynanchi wilfordii Radix roots and evaluated the effect of cynandione A on receptor activator of nuclear factor-${\kappa}B$ ligand (RANKL)-induced osteoclast differentiation. We found that cynandione A significantly inhibited osteoclast differentiation stimulated-RANKL in RAW 264.7 cells. Cynandione A conspicuously inhibited the mRNA and protein expression of matrix metallopeptidase 9 (MMP-9), tartrate-resistant acid phosphatase (TRAP) in cynandione A treated with RANKL. Taken together, our results demonstrated that Cynanchi Wilfordii Radix may be useful treatment option of bone-related disease such as osteoporosis leads to fracture of bone and rheumatoid arthritis.

The purpose of this study is to development of a teaching-learning model for active learning in engineering education. For this, the adequacy between educational objectives and active learning activities is verified and furthermore an "active learning teaching-learning model" is suggested. This suggested teaching-learning model is expected to supplement weakness of traditional lecture-type teaching-learning activity. Based on the literature review, first, the representative activities of active learning were derived. there are twenty active learning activities, which compose of five of individual learning activity, five of pair-learning activity and five of group-learning activity, and five of alternative- learning activity. In addition, a survey on adequacy between designed active learning activities and learning outcomes were conducted to ten educational experts. Lawshe's content validity calculation method was applied to analyze the validity of this study. Second, five teaching-learning principles, such as thinking, interaction, expression, reflection, and evaluation were derived to develop an "active learning teaching-learning model" which supplements lecture-type classes and then the "TIERA teaching-learning model" which consists of five stages was designed. Finally, based on the survey on educational experts, adequate active learning activities were proposed to apply in each stage of the "TIERA teaching-learning model" and as a result the TIERA model's active learning activities were developed. The result of this study shows that some activities of active learning are appropriate to induce high cognitive learning skills from the learners even in traditional lecture-type classrooms and therefore this study suggests meaningful direction to new paradigm of teaching-learning for engineering education. This study also suggests that instructors of engineering education can turn their traditional teaching-learning activities into dynamic learning activities by utilizing "active learning teaching-learning model".
