ABSTRACT
@# Objective To explore the level of difficulty in the activity and participation among persons with disabilities and chronic illnesses in Hong Kong SAR. Methods A cross-sectional study with 954 subjects of disabilities and chronic illnesses based on the WHO Disability Assessment Schedule II (WHODAS 2.0). Results People with disabilities and chronic illnesses were facing moderate to severe level of difficulty in the activity and participation. Their most difficult aspects were found in the domestic responsibilities and social participation. Conclusion The Hong Kong SAR government should explore and adopt the Classification of Functioning, Disability and Health (ICF) framework and take the elements of activity and participation into consideration for the planning and formulation of rehabilitation policies and services which in the long run, help safeguard the rights of persons with disabilities and chronic illnesses and realize the implementation of the Convention on the Rights of Persons with Disabilities.
ABSTRACT
Objective:To build 3D digitized face model of unilateral orbital defect and to realize imitating design of defect section.Methods:Phase measuring profilometry was employed to acquire a 3-D digitized face model with open eyes.By Geomagic software,the image of normal orbit was extracted and mirrored with the image of the deformed side of the orbit.Results:A 3-D digitized face model of unilateral orbital defect was successfully reconstructed and 3-D normal orbit data of defect section was acquired.Conclusion:The use of phase measuring profilometry and RE software is a convenient and effective method to the computer-aided design for the restoration of unilateral orbital defect.

0.05).Conclusion: Feasibility of galvanic corrosion between Fe-16Cr-2Mo soft magnetic alloy and dental alloys used in clinic application can be omitted.
ABSTRACT
Objective: To study the property of galvanic corrosion of soft magnetic alloy and 4 kinds of dental alloys in simulated oral environment. Methods: 6 samples of Ni Cr, TA 2, Ti75 and 30 of Fe 16Cr 2Mo in the size of d 15 mm?3 mm were prepared and put into artificial saliva. An electrochemical method was used in the measurement of electric potential of corrosion (Ecorr), potential dynamic polarization and galvanic current density of different galvanic couple, the anticorrosive property of four galvanic couples was analyzed statistically. Results: The ecorr value(mV) of Ti75, TA 2, Co Cr,Fe 16Cr 2Mo and Ni Cr was -138.31?2.89, -150.35?1.04, -186.21?3.79, -218.35?0.84 and -240.49?1.73 respectively ( P
