The purpose of this study was to investigate the inhibitory effect of fluoride in the water and milk on tooth enamel dissolution by commercial beverages. 3 weekold 60 female sprague-Dawley strain were divided into four groups and given the following dosage of fluoride in the drinking water:0,1,5 and 50ppm for six and twelve weeks ad libitum. Upper incisors were prepared for specimen with low speed dental disc.The slabs of each incisors were embedded in unsaturated polyester,polished with #1,200 silicon carbide paper and aluminisilicate powder.Three kinds of beverage were selected for test medium and enamel slabs of rat incisors were dipped for 60 and 120 minutes in each beverage.Surface microhardness was examined before and after dissolution with beverage. All collected data were analyzed using the SAS package.Differences between groups were compared by the one-way ANOVA,Duncan's multiple range test and ANCOVA procedures. Corresponding p-values were considered significant at the values less than 0.05. The obtained results were as follows: 1. Surface microhardness was significantly increased both 6 and 12 weeks groups compared with control group. Surface microhardness of high fluoride groups were also proportionally increased with increasing concentration of fluoride both in the water and milk. 2. There were significant differences of inhibitory effect of surface microhardness after 60 and 120 minutes emersion periods,and both at 6 and 12 weeks group in the veverage B and C,but not appeared in the beverage A. 3. The inhibitory effect of enamel dissolution was higher in the 12 weeks group than 6 weeks group both at the water fluoridation and milk fluoridation. 4. The differences of micro hardness between before and after emersion in the beverages were larger in the milk fluoridation groups than water fluoridation groups.

목적: 전공의는 여러 유해인자에 노출되어지고 있으며 과중한 업무로 인한 수면 부족에 시달리고 있다. 본 연구는 전공의의 건강상태의 기초 자료를 제공하고 향후개선 방안을 도출하기 위하여 시행하였다. 방법: 연구대상은 2000년 3사관학교와 국군군의학교에 입소한 전체 1,316명 중 전공의 수련과정 없이 입대한 의사와 치과의사, 한의사를 제외한 881명을 대상으로 설문지를 배포하여 784부(회수율: 89.0%)를 회수하고 이중 분석이 가능한 704(79.9%)명의 자료를 최종 분석하였다. 결과: 월평균 당진횟수는 레지던트 1년차에서 19회 정도이었다. 당직 시 평균 수면시간은 레지던트 1년차에서 4시간미만 이었다. 수련기간 동안 전공의의 20%이상에서 방사선, 레이저, 살균소독제, 마취가스, 항암제에 노출되었으며 예방대책은 방사선과 레이저의 노출의 경우 35%정도를 제외하고는 10%내외로 조사되었다. 연구대상자중 91.1%에서 수련기간 동안 주사침이나 시술에 의해 손상을 입었으며 그 중 본인이 감염된 경우는 HBV 2.3%(4명), HCV 0.6%(1명)으로 조사되었다. 응답자의 28.4%에서 자신의 직업에 불만족 하였으며 96.5%가 과중한 업무부담을 느꼈고 69.5%가 동일한 임금수준에서 직업을 바꾸고자 한다고 응답하였다. 결론: 전공의는 수련기간 동안 물리적, 화학적, 생물학적 유해인자에 노출되고 있었으나 이에 대한 보호나 예방대책은 거의이루어지지 않고 있었으며 과중한 업무부담으로 수면부족을 초래하여 가장 중요한 환자 진료에 지장을 받고 있었다. 수련기간 동안 대다수가 의사로서 직업에 대한 흥미를 가지고 있었으나 업무부담과 진료이외의 업무 등으로 소득과 조건이 비슷하다면 다른 직업을 선택하고자 하였다. 이상의 결과를 토대로 전공의들을 위한 유해인자의 보호대책 및 예방대책을 마련하며 과중예방대책이 마련되어야 하고 업무환경개선 및 업무로 인한 건강장해에 대한 정당한 보상이 향후에 마련되어야 할 것이다. Objects: Residents are exposed to various hazards and harassed by sleep dificiency due to overwork. This study was performed to outline the health condition of residents and develop the ways of improving it. Mehtods: A questionnaire was distributed to 881 army doctors who enrolled at the Korea Third Military Academy and The Armed force Health Service School in 2000 with the exception of medical doctors who joined the armed service without going through intern and resident periods, dental and oriental medical doctors. 784(89.0%) of the 881 questionnaires were resident of which 704 cases (79.9%). This should actually be 89.0% were regarded for analyses as being reliable data. Results: More than 20% of residents were exposed to radiation, laser, disinfectants, anesthetic gas, and anticancer drugs during their training periods with preventive neasures for each of these hazards taken in about 10% of the cases of the lesser hazards but in about 35% for the hazards from radiation and laser. 91.1% of residents had experience of needlestick injuries during theirtraining periods with over 36.3% being exposed to patients with infection during that time. The cases contracting HBV and HCV diseases due to pricking are 2.3% and 0.6% respectively. The average number of night duties per month during a one-year resident's period was about 10. The average sleeping time on duty during a one-year residents was less than 4 hours. 28.4% of respondents were not satisfied with their occupation, 96.5% delt tired from overwork and 69.5% wanted to change their occupation to another that would pay the same salary. Conclusion: Residents are exposed to harmful physical, chemical and biological factors, but the preventive care seldom undertaken. In addition, their overwork brings about lack of sleep which causes them problems when giving medical treatment to patients during their training periods. Despite the resident's interest in an occupation as a doctor, many intend to select other occupations if they can receive the same salary. According to the above results, preventative systems and measures should be prepared with environmental improvements for residents, and proper rewards for their overwork should be accomplished

Double primary cancers are two independently developed cancers in an individual. There have been some reports on double primary cancer since Billroth reported it for the first time in 1879. Double primary cancer of the stomach and esophagus has been revealed a very low incidence worldwide. The incidence of an esophageal cancer with another primary cancer is reported to be 9.5∼27%, but double primary cancers in the esophagus and stomach have been rarely reported to our knowledge. In this study, we present here a case of double primary esophageal and stomach cancer in a 66-year-old man because of progressive dysphagia.
