For women in Korea, the overall incidence of breast cancer has been increasing recently. Long-term survival in breast cancer currently rests on detection and appropriate therapy at the earliest possible stage, with survival being excellent in patients whose cnacers are discovered at small size and without dissemination. Discovery of lesions at the smallest possible size is therefore desirable.
From July 1st, 1990 through Sep. 30th, 1990, KAP on early detection of breast cancer survey among 260 women over age 35 was carried out at Youngdong Severance, Chungmu and Cha Hospital.
The results were as follows:
1. Film-mammography users are better educated(p<0.05) and higher economic status(p<0.05) than nonusers.
2. Regarding BSE(Breast Self Examination), 17.7% said they practiced BSE monthly and there is no significant difference on practical aspect of BSE between users and nonusers.
3. Women's attitudes toward breast cancer, users have more appropriate insight(p<0.05).
4. Women's attitudes toward screening mammography, users show more active response on breast cancer screening in asymptomatic period(p<0.05), and 58.7% women knew that mammography was useful in detecting breast cancer at an early stage.
5. When nonusers were asked why they did not have a mammography, the most common responses related to poor information(27.9%) and not knowing the test was necessary(22.1%).
6. The experience of film-mammography itself dose not seem to be a negative one, and more acceptible cost was cited for screening test.

For the evaluation of the epidemiologic state of mumps and efficacy of mumps vaccine the field evaluation 261 population from September 1990 in a October 1990 in a part of large city that was reported as mumps-outbreak area by a family practitioner.
The results were as follows.
1. Boys were 132(50.6%) and girls were 129(49.4%) and the case of mumps patients were 74(28.4%). The incidence by age group was 7.0% in 1-4 years, 35.5% in 5-6 years, 38.0% in 10-14 years and 7.7% in 15-18 years.
2. Mumps-vaccination rate was 88.9% in total study population, 72.7% in patient group and 94.7% in non-patient group.
3. The percentage that the vaccination was injected to the children before 2 year old was 94.2%. The 5 cases(2.2%) were injected twice at 9 months and 15 months of age.
4. The occurrence of mumps was mainly in spring and summer(97.3%).
5. The order of clinical findings was parotitis (100%), fever(85%) and sore throat(80.4%).
There were no difference between vaccination and non-vaccination group in parotitis duration, frequency of bilateral parotitis, fever duration, the number of hospital visit and school absence.
6. The incidence of mumps was 43.9% in the vaccinee and 75.0% in the non-vaccinee, therefore efficacy of mumps vaccine was 41.5%.
