Abstract
As the population of senior people has been increased rapidly during the past 30 years in Koera, the health policy and related research in this field are strongly demanded to manage various problems which can be derived from the gerontic phenomenon. We estimated the death rates up to 2010 using the annual mortality data published by the National Statistical Office from 1970 to 1995 by time series analysis and calculated the survival curves, life expectancy by life table method with modified Graville's formular and proposed several measures which can be used in describing the theory of retangularization of survival curves and compression of mortality hypothesis. According to the results, the relative and absolute rectangularization and the convergency of survival curves were observed, and all the Keyfitz's H, NH, SD, and CV decreased while the life expectancy increased in the period of 1970 to 2010. So we conclude that the hypothesis of mortality compression suggested by Fries explains the changing pattern of aged population in Korea very well.

Abstract
Many problems have been stated in the surveillance system of notifiable acute communicable diseases in Korea. Lack of objective tools for detecting epidemic is one of the most fundamental. We propose a statistical standard for detecting epidemic of those diseases that could be easily and promptly applicable to the existing data. Suggested standard measure is computed from the median and the spread of upper and lower hinge(spr(H)) which is robust to the assumption of normal distribution, so frequently used in exploratory data analysis as a measure of variation, and the results are compared with those of existing method using recent 3 years from January 1994 to December 1996 of monthly data of 8 notifiable acute communicable diseases in Korea. Monthly pattern of statistical epidemic between the proposed (median) and existing(mean) methods is similar. Therefore, we propose that the statistical epidemic should be defined when the current occurrence exeeds the standards of both methods. When the data collection is made weekly than monthly, the proposed method of determining the time of epidemic will be much helpful for the management of notifiable diseases.
