A chemiluminescent method with gold nanoparticles for determination of vitamin C has been presented. Gold nanoparticles highly increased chemiluminescence intensity of lumimol-H2O2 system by its catalytic effect. The gold nanoparticles enhanced chemiluminescent method is applicable for the determination of an antioxidant such as vitamin C. When vitamin C was introduced to the lumimol system with gold nanoparticles, chemiluminescence intensity was reduced with the concentration of the added vitamin C. Low concentrated vitamin C solutions in the range of 1×10(-3)-1×10(-9) M were produced reduced chemiluminescence intensity of lumimol-H2O2 with gold nanoparticles system.

A chemiluminescent method with silver nanoparticles for determination of cysteine has been presented. Silver nanoparticle highly increased chemiluminescence intensity of lumimol- H(2)O(2) system by its catalytic role. The silver nanoparticle enhanced chemiluminescent method is applicable for the determination of an amino acid such as cysteine. When cysteine was introduced to the lumimol system with silver nanoparticles, chemiluminescence intensity was reduced with the concentration of the added cysteine. Low concentrated cysteine solutions in the range of 1 × 10(-3) - 1 × 10(-7) M were produced reduced chemiluminescence intensity of lumimol-H(2)O(2) silver nanoparticle system.

Purpose:This study was investigated consumers’ and optometrists’ perception about spectacle frame in Busan and Ulsan to find on the right progress direction for conversion of spectacle frame into medical devices. Methods: 137 consumers surveyed in Busan and Ulsan and 100 optometrist surveyed in ‘Busan continuing education of optometrist’ filled in a questionnaire, then we compared and analyzed the results. Results: The 79% (108 people) of consumers and 94% (94 people) of optometrists agreed to conversion into medical devices of spectacle frame. The reason was shown that the consumer expected to improve the optometrist reliability and the optometrist expected to improve the optometrist professionalism. While, the 21% (29 people) consumer and 6% (6 people) optometrist opposed to conversion of spectacle frame into medical devices. The reason was revealed that the consumers were concerned about increase of medical insurance cost and the optometrists were concerned about that the spectacle frames can also be sold by medical device stores, not only by optical shops. Conclusions: The result of the survey was shown that the most of consumers and optometrists in Busan and Ulsan agreed on perception toward a conversion of spectacle frame into medical devices. But, we are considered that consumers’ and optometrists’ active attention and support are needed, with sequential implementation reflecting the concerns for this.
