Abstract
While there has not been a nationwide cancer incidence data yet, it is necessary to consider a preferable method for estimation of nationwide cancer incidence under the cancer registry system in Korea. Some papers and texts related to estimate a nationwide cancer incidence were searched and reviewed. It could be summarized into 5 major methods: (1) for having only mortality data for all cancers, (2) of using major demographic factors, (3) of using nationwide mortality data, (4) of using nationwide mortality and survival data, and (5) of considering cancer risk factors.

Abstract
The present study studied the effects of examination stress on the health practices in 69 male medical students prospectively over 3 month period. Average age of the subjects was 23.4 years(range, 21 27). The questionnaires asking the health practices of the previous week were administered on three occasions, during the one week after the one-week midterm examination and examination-free periods of one month before and after examination. Increases in academic demands result in changes of health practices which were statistically significant increased consumption of smoking and mixed drinks and frequency of missed breakfast, and decreases in alcoholic beverage consumption, hours of sleeping and exercise as well as consumption of vegetables, principal foods and oils. These result support the hypotheses that examination stress may exert negative effects on the health practices.
