The purpose of this study is to find out factors(shoulder level, acromion-occipital length, spine alignment, spine-scapula inferior angle length) of pain of neck & shoulder by 3 Dimensional Moire Scanner. 50 female student s aged 20 to 25 years old participated who lived in Sun-cheon si Jeonnam. They were examined with three measurement methods(Visual Analogue Scale : VAS, Algometer, 3 Dimensional Moire Scanner(IBS-2000). According to the results of multiple regression analysis. 1) There was a significant difference with shoulder level and spine-scapula inferior angle based on VAS. 2) There was a significant difference with shoulder level based of Algometer measurement value in Rhomboid muscles.

This paper proposes a grating scanner which is driven by a stack-type piezoelectric element. The mechanism of the grating scanner is based on flexure hinges. Using some constraints, the compliant mechanism is designed and then verified by Finite Element Analysis. The designed compliant mechanism is manufactured by wire electro-discharge machining, and then integrated with a stack-type piezoelectric element for actuation and a capacitance displacement sensor for measuring ultra-precision displacement. Experiments demonstrates the characteristics and the performances of the grating scanner using the terms of working range, resonance frequency, bandwidth and resolution. The grating scanner is applicable to a Moire interferometry for measuring 3-dimensional microscopic surface.
