Purpose: In order to find suitable size of soft contact lens for different ages group of elementary student to adults, visible iris diameter(horizontal, vertical) and palpebral aperture size were measured. Methods: Visible iris diameter (horizontal, vertical) and palpebral aperture size were measured in different age groups of total 514 subjects (1028 eyes) who have no eye disease and none history of surgery included cosmetic purpose. Results: No significant difference was found in iris diameter of both horizontal and vertical direction for different groups of age and sex but horizontal direction of palpebral aperture size in middle school students and university students groups and vertical direction of palpebral aperture size in high school student group shows significant difference (p<0.05) by sex. Horizontal visible iris diameter, vertical visible iris diameter, horizontal palpebral aperture size and vertical palpebral aperture size shows significant difference in difference age and sex. Conclusions: Visible iris diameter and palpebral aperture size are affective factor for soft contact lens diameter decision, especially it should considered more intensive for removing uncomfortable feeling of lens wearer.

This study was an attempt to investigate the external ocular morphology on the Korean female adult. The following results were obtained: 1. The optimum length of the distance of the innercanthus was 35-36mm. But the subjects between the ages of 18-19 had a wider range than those between the ages of 20-25 ages. 2. The optimum length of palpebral fissure was 30-31 mm. where as the right and left eye produced similar results. 3. The optimum width of the palpebral fissure was 8mm, and the right and left eye produced similar results. 4. At near distance, almost all the subjects PD was 28-31mm(76.7%), and the right and left eyes produced similar results. 5. At far distance, almost all the subjects PD was 30-33 mm(75.8%), but in the subjects aged 18-21 ages, the length of the right eye was longer than the left eye.

This study was researched the external ocular structure on the korean young age. The results was as follows; 1. On the distance of innercanthus, the average length was 38-40 mm. In the twenties age, the male was longer then the female. 2. On the length of palpebral fissure, the average length was 35-37 mm and right and left eye was similar results. But, the male was longer than the female. 3. On the width of palpebral fissure, the average width was 7-8mm and the male and female was similar results. 4. At the near distance, the average PD was 29-33 mm, but in the twenty age, the left eye of male was longer than the right eye. On the other hand, In the female, the results was reverse. 5. At the distance, the average PD was 31-32 mm, But, In the teens, the male and female was similar results. On the other hand, In the twenties age, the male was longer than the female.

Commercialism of journalism adheres to short-term profit, and the decrease in quality. Commercialization means the process that is deepened low quality of journalism. It is for a purpose and a means to have been transposed. The mid term of 1990's, deregulation of media and commercialism of journalism were gaining power in the developed countries. Korea has come to the similar condition which is most laws of press and broadcasting are deregulated. There is also concern to the commercialization of journalism in Korea. Four broadcasting channels (cross-ownership media) enter in media market, and a huge change is expected. It is for concern regarding commercialization of journalism not to stop to a baseless anxiety. In order to consider more deeply the problems of commercialism, I have approached instances of the art world and the developed countries. Through this, I declared the importance of ethics of journalists.
