Purpose: This study was to exam me the effects of auricular acupuncture on insomnia in Korean elderly. Method: The study design was a triangulation study. Subjects were 40 elderly who were 65 years and over in Seoul, and 10 subjects for a qualitive study who were saturated with interviews and observation. The first auricular acupuncture was applied for three days, and this was applied to subjects on a 5 times series. The quantative data was analyzed by SPSS PC+ and the qualitive data was analyzed by driving of core meaning and abstract concepts using a semi-structural interview and observation. Result: I. The experimental group had higher significant sleep scores than that of the control group (t=32.739, p=.001). 2. The experimental group had higher significant self- satisfaction scores on sleep than that of the control group (t=30.049, p=.001). 3. In the qualitive study, insomnia characteristics before application of auricular acupressure therapy were confirmed by physical dysfunction, recall of past, and psychological dysfunction. Insomnia characteristics after application of auricular acupressure therapy were confirmed by recovery of physical dysfunction, improving recall of past, and recovery of psychological dysfunction. Conclusion: Auricular acupuncture was effective on insomnia in Korean elderly.

One of the main problems in 3D shape measuring systems that use the triangulation of line-shaped laser light is precise center line detection of line-shaped laser stripe. The intensity of a line-shaped laser light stripe on the CCD image varies following to the reflection angles, colors and shapes of objects. In this paper, a new center line detection algorithm to compensate the local intensity variation on a line-shaped laser light stripe is proposed. The 3-D surface shape measuring system using the proposed center line detection algorithm can measure 3-D surface shape with enhanced measurement resolution by using the dynamic shape reconstruction with adaptive pattern clustering of the line-shaped laser light. This proposed 3-D shape measuring system can be easily applied to practical situations of measuring 3-D surface by virtue of high speed measurement and compact hardware compositions.
