Purpose: The purpose of this study was to examine the eyesight and life habits of college students in an attempt to provide some information on the protection of their eyesight. Methods: The subjects in this study were 311 students in the department of dental technology at a college of health, on whom a survey was conducted. A crosstabulation analysis was carried out to show the joint distribution of general characteristics and several variables involving the use of glasses or contact lenses and life habits. Results: 77.5% of the students currently wore glasses due to weak sight. 9.3% took an eye test on a regular basis, and 31.2% did that every six months. As for the length of the length of daily mean reading time, 55.3% spent one hour or less reading books. The most common distance between eyes and books during their reading(44.7%) was 21 to 25. Concerning a reading posture, the biggest group(54.3%) lay down or lay on their face while they read books. 45.0 % spent less than an hour watching TV per day on average, and 27.0% were on the computer for 30 minutes to less than an hour per day on average. The greatest group(63.0%) made use of basic indoor lighting when they were on the computer at night, and 62.1% saw eye doctors to take an eye test. In relation to how to protect eyesight, the biggest group(50.5%) spent less time being on the computer. Conclusion: As the eyesight of college students fails due to reading, TV, computer, and improper ways and posture of doing or using those things, every college definitely should provide education on eye health as one of general education courses.

도재 수복물 제작을 위해 자연치아의 색조를 분석하는 방법으로는 색견본 (shade guide)을 이용하는 시각적인 방법과 기계를 이용하는 방법이 있다. 그중 통상적인 육안 관찰을 통해 색조를 선택하는 것은 임상에서 가장 많이 이용되고 있는 방법이기는 하나 주관적이며 일관되지 않은 결과로 신뢰성의 문제가 제기되었으며 자연치의 색조는 매우 다양하여 같은 치아라 할지라도 부위별로 다양한 색조를 가지기 때문에 단순히 shade tab을 이용한 색조 비교만으로는 정확한 치아의 색조 특성을 나타내는 것이 불가능한 것으로 알려져 있다. 한편 지속적인 기술발달로 computer color matching system, 치과용 비색계, 분광 측정기 등의 기계를 이용한 치아 색조 측정 방법이 이의 대안으로 제시되고 있다. 기계를 이용한 방법은 색조 선택에 있어 객관적이며, 재현성이 있는 정확한 정보를 술자에게 제공한다. 이에 본 연구에서는 광원, 개인, 술자의 숙련도에 따라 육안과 기계를 통한 관찰 시 치아 색조 선택의 정확성을 확인하기 위한 실험을 시행하였다. 첫 번째 실험에서는 치과대학병원 전공의인 1명의 검사자가 10명의 피검자를 오전, 정오, 오후 각 3번의 측정을 통해 시간대별 자연광하에 육안, 기계 측정의 색조 선택 정확성을 분석하였다. 두 번째 실험에서는 5명의 치과대학병원 전공의와 5명의 치과대 학생, 총 10명의 검사자가 10명의 피검자를 정오에 육안, 기계 관찰을 통해 개인차에 따른 정확성을 실험하였다. 세 번째 실험에서는 두 번째 실험의 결과를 5명의 치과대학 전공의, 5명의 치과대학생 군으로 나누어 숙련도에 따른 육안, 기계 색조 선택의 정확성을 분석하였다. 실험 결과, 첫 번째 실험에서는 기계 측정 결과가 육안 측정보다 통계적으로 유의한 차이를 보이며 (P < .05) 색조 선택의 정확성을 나타내었고, 두 번째 실험에서 역시 기계 측정시 개개인의 육안 측정에 의한 색조 선택 값에 비해 재현성 및 정확성이 높았으며 통계적으로 유의한 차이를 보였다 (P < .05). 세 번째 실험에서 이전 실험의 결과를 숙련자, 비숙련자 군으로 나누어 분석한 결과 군 내 기계 측정값이 육안 관찰값보다 숙련도에 상관없이 정확도가 높으며 통계적으로 유의한 차이를 보였다 (P < .05). 하지만 군 간 육안, 기계 측정값을 비교 시 통계적으로 유의한 차이를 보이지 않아 치아 색조를 육안, 기계 측정할 때 술자의 숙련도가 큰 영향을 미치지 않음을 알 수 있었다. 따라서 기계를 이용하는 치아 색조 측정 방법이 색견본을 이용하는 시각적인 방법에 비해 더 정확하기는 하지만 어느 정도의 측색 오류를 고려해야하며 수복물 제작 시 정확한 재현과 효과적인 정보 전달을 위해 시각적인 방법과의 병행이 필요할 것으로 사료된다.

Medical personnek are one of several groups that have been reported to have a high incidence of hepatiris B. It is also thought that the occurrence rate of hepatitis B surface antigen(HBsAg), aserologic marker for hepatitis B virus(HBV), is expected to be high in the dental personnel who are frequently exposed to the blood and saliva of the patients. Although many studies have been done to determine the HBsAg status of virus groups, limited investigations have been performed on dental personnel, especially in this country. The main purpose of this study was to identify HBsAg positivity among dental students, interns, and residents who would be expected to be a high risk group of hepatitis B infection. Screening test for HBsAg of a dental school population was performed by indirect hemagglutination(IHA)in 1982. The results were as follows : 1. Thirty four out of a total 362 persons(9.4%)tested in the study had positive response for HBsAg in their serum samples. 2. Twenty seven out of 320 dental students(8.4%)had positive for HBsAg, and in Senior class 12 out of 82 dental students (14.6%)had positive response that was the highest incidence among dental students group. 3. Seven out of 42 interns and residents(16.7%)had positive for HBsAg, and it was the highest incidence in this dental school population.
