摘要

The time-activity patterns distribution is necessary to calculate population exposure. This objective of this study was to characterize time-activity pattern of Korean population in three different seasons. The time-activity data of a total of 26,988 subjects older than 10 years was provided by the Time Use Survey of the Statistics Korea (KOSTAT). The survey was conducted in summer, fall and winter. The subjects were selected using probability proportional extraction method from 800 administrative areas of Korean in 2014. Each subjects completed a diary with 10-minutes interval for two consecutive days regardless of day of week. The location codes of the diary were classified into 5 microenvironments: indoor at home, workplace/school, restaurant/bar, transportation and other indoor/outdoor locations. They also completed a questionnaire including demographic, socioeconomic and family information. This study analyzed only weekday data. The time-activity pattern was analyzed by gender, age-related, urban-rural difference in summer, fall, and winter seasons. The times spent in different microenvironments were similar in the three seasons. The most time was spent at home (62-64%) followed by workplace/school (18-20%), transportation (6-7%), bar/restaurant (2%) and other indoor/outdoor locations (9-10%) in all seasons. The times spent at home and workplace/school were different by gender. Male spent 10-11% less time at home than female. However, male spent 7-8% more time at workplace/school than female. The times spent at home, workplace/school and other locations were different by age group. The teenage group spent 52-61% at home and the senior group spent 74-79% at home. The other age groups spent 57-62% at home. The time spent at workplace/school was 5-6% in the senior group, while times at workplace/school were 22-34% for the teenage group and 19-24% for the other age group. The times spent at different microenvironments were not different by urban-rural status. The difference of time spent at each microenvironment was less than 2%. Overall time location data of Korean population were different by age and gender but not urban/rural status in three seasons. However, further analysis is necessary to compare daily time activity pattern by the variables and determine interaction between the demographic variables on time activity patterns. Since time activity pattern is associated with exposure, population exposure assessment shall include difference by age and gender.
