Information about time spent in microenvironments plays a critical role in exposure assessment of the person concerned, considering that personal exposure relies on the characterization of time-activity patterns of the population at risk as human activities impact the timing, location, and level of personal pollutant exposure. The purpose of this paper was to present the time-activity patterns of Korean adults from a population-based study, and to determine the time spent each day in microenvironments. The population-based study collected time-activity data of about 46,000 adults for two consecutive days on weekdays (n=28,152) and weekends (n=18,800). The mean times spent at one’s own house, workplace or school, other’s house house, restaurant or bar, other places, and transportation related to the whole sample of 28,152 people were 14.90 hrs (62.08%), 4.28 hrs (17.81%), 0.24 hrs (1.01%), 0.51 hrs (2.14%), 2.45 hrs (10.21%), and 1.62 hrs (6.74%) on weekdays, respectively. Looking at the total time spent indoors by adults in different countries, the following four countries were ranked as follows, from lowest to highest: USA > Canada > Korea > Hong Kong. Due to cultural, socioeconomic and climatic differences, it may not be appropriate to directly apply statistical data of other countries to the Korean situation. This paper provides information on how the proportion of persons in different locations changes by time of day, on weekdays and weekends. Here, we can see that over 90% of respondents were in a residence from about 11 PM to 5 AM, and the largest proportion of respondents in workplaces or schools and other places is found between 8 AM and 5 PM.

왕지네는 전통 생약중 하나로 유효물질 탐색 및 약리활성 연구 등의 주요한 생물자원으로 한방에서 중풍, 해독, 관절염 등의 민간 약제로 이용되고 있다. 이에 왕지네를 실내 사육하기 위하여 먹이 및 활동특성을 조사하였다. 먹이를 갈색거저리구, 닭고기구, 돼지고기구, 닭고기+돼지고기 혼합구, 닭고기+ 돼지고기+갈색거저리 혼합구로 나누어서 실험한 결과, 성충 1마리당 먹이량, 체중증가량 등으로 볼 때, 갈색거저리보다 닭고기, 돼지고기, 닭고기+돼지 고기 혼합구의 발육이 우수하여 왕지네 먹이로는 닭고기, 돼지고기 등이 적합한 것으로 생각된다. 또한 카메라 영상장치를 이용하여 1개월 동안 왕지네의 활동시간대를 조사한 결과, 분산유충은 낮 12시에 가장 활발하고 먹이활동 은 오후 4시-8시 사이에 이루어졌다. 성충은 활동 시간대가 저녁 9시-새벽 6시이었고, 새벽 0시-2시가 가장 활발하였다. 먹이활동은 오후 9시-새벽 2시에 먹는 것으로 나타나, 지네 먹이를 줄 때는 가능한 저녁시간에 주는 것이 먹이의 신선도 유지와 부패를 막는 방법이라고 판단된다.

Objective : This study examined the impact of a sixteen-week time-use intervention perio on the depression and rehabilitation motivation of stroke patients with psychological difficulties.Methods : Ten stroke patients who were divided into an experimental group and a control group participated in this study from May 2014 to August 2014. Depression changes were measured using a Beck Depression Inventory (BDI), and their rehabilitation motivation was evaluated using the Rehabilitation Motivation Scale.Results : The results of the present study showed that the experimental group and control group presented significant differences before and after intervention in terms of their depression and rehabilitation motivation. However, after intervention, the depression and rehabilitation motivation did not differ between the two groups.Conclusion : The results of this study indicate that time-use intervention was effective in improving the depression and rehabilitation motivation of stroke patients, and therefore time-use intervention with occupational therapy will be useful as a clinical method for improving their level of depression and rehabilitation motivation.

This study was a time activity pattern assessment focused on transportation in subpopulation groups using the ‘Time-Use Survey’ conducted by the National Statistical Office in Korea in 2009. The time activity patterns of transportation on weekdays were analyzed, looking at average travel time in Seoul, Gyeonggido and the whole country. Various subpopulation groups were classified such as students, the elderly, workers and housewives. The population of Gyeonggido had a higher average transportation time than that of Seoul. Workers showed the highest weekly average travel, while the students group showed the lowest tendency. The times spent in walking, bus, subway and taxi were the highest in areas other than Gyeonggido, where the use of private vehicles such as car was higher. Therefore, exposure to hazardous air pollutants may vary depending on the transportation method and time spent. This results indicate that time activity pattern assessment on transportation may be an important element of exposure assessment.

This paper reviews an implementation strategy of activity breakdown for the assessment of process time. In addition, the study proposes the classification models for estimating the process time of Time-Driven Activity-Based Costing (TDABC) based on various types of activity breakdown structures, including activity interface perspective, activity decomposition perspective and activity priority perspective.

Hazardous air pollutants such as NO2, VOCs and PM10 were measured Daegu, Korea in major micro-environments,where housewives spend the most of their time, and personal exposure times were estimated by using time activitypatterns and exposure scenarios. The major microenvironments of housewives were selected using the ‘Time-UseSurvey’ conducted by the National Statistical Office in Korea in 2009. A total of 4,514 (weekdays) and 3,063(weekends) housewives were recruited for the ‘Time-Use Survey.’ It seems that housewives are spending about80% of their time in the house, and about 5% of their time outdoors during weekdays and weekends. The indoor/outdoor ratio of the average concentration of NO2 was more than 1, which indicated that the source was indoors.Toluene was shown to have higher concentrations indoors than outdoors. Ethylbenzene and xylene displayedsimilar characteristics to toluene, and the concentration ratio for indoor/outdoor was shown to be 1.29 ± 0.76 and1.04 ± 0.45, respectively, higher concentrations indoors. Based on the results of the time activity patterns ofparticipants, 3 kinds of exposure scenarios were formulated. The spent time and air concentration in eachenvironment were assumed as normal and lognormal distribution, respectively. And then the Monte-Carlosimulation was conducted. According to the result of the simulation, the exposures to hazardous air pollutantsrevealed an increasing pattern as housewives visits other indoor environments such as supermarkets.

In this study, we estimated nitrogen dioxide (NO₂) concentrations in microenvironments where residential indoor, residential outdoor, other indoors, and transportation using measured personal exposure and multiple linear regression analysis of time-weighted average model, and compared with measured NO₂ concentration in microenvironments. Measured residential indoor, outdoor and other indoor NO₂ concentration was 22.22±9.59 ppb, 23.64±9.62 ppb, and 22.07±13.90 ppb, respectively. NO₂ concentrations in residential indoor and outdoor, total outdoor, other indoor, and transportation by multiple regression analysis were significantly estimated as 20.48 ppb, 32.79 ppb, 24.35 ppb, and 28.82 ppb, respectively (p= 0.000). Measured and estimated NO₂ concentration were similar with each other, therefore NO₂ concentrations in each microenvironment were able to be estimated using time-weighted average model and personal exposure with multiple regression analysis.

The information about time spent in microenvironments plays a critical role for an exposure assessment of the person concerned, considering the personal exposure relies on the characterization of activity patterns of the population at risk and human activities impact the timing, location, and level of personal pollutant exposure. The purposes of this paper were to present indoor time activity patterns of Korean from a population-based study and to determine individual factors of time spent in microenvironments. The population based study collected time activity pattern of about 32,000 Korean for two consecutive days. The mean times spent at home, other indoors, outdoors, and transportation in related to the whole sample of 19.025 people are 14.23hrs(59.3%), 6.80hrs(28.3%), 1.26hrs(5.2%), and 1.75hrs(7.3%) in weekday, respectively. Database provides information on how the proportion of persons in different locations changes by time of day in weekday. Here, we see that over 90% of respondents were in a residence from about 11 PM to 5 AM, and the largest proportions of respondents in offices, factories, schools and public buildings occur between 8 AM and 5 PM.

Purpose: This study was to verify the difference between reaction time of information processing and decision making information related with physical activity according to exercise self-schema. So it would have the hypothesis that exercise self-schema affected to judgement, remember and expectation of the content related with physical activity. Methods: The participants of experiment were 36(male:15, female21,Mage=21.25). Task was presented at computer screen. Participants reaction time and contents were saved automatically. And it was measured the physical activity’s amount for 7 days through questionnaire. All anaysis were conducted by SPSS 18.0 and AMOS 18. Results: It was shown that the participants who had higher exercise self-schema had faster information processing about physical activity content than the participants who had lower exercise self-schema. Also group of higher exercise self-schema had more vocabulary comments. And at the expect behavior related physical activity, the group of higher exercise-self schema seek more physical activity than the group of lower exercise self-schema. Finally, higher exercise self-schema group had more physical activity. Conclusion: it had identified that exercise self-schema was significant factor at information processing related physical activity. So it is needed to study and develop the program which help developing exercise self-schema.

The time management and allotments for various activities of daily life is much different by age groups. This study analyzes time allotments of different age groups for various activities of daily life to figure out the change of main activity by aging through 2009 time use survey by National Statistical Office. Especially we focus on time allotments of rural elderly population and intangible factors for life quality of people instead of physical and environmental elements. The results show that there is a large gap of time allotments for paid and unpaid working time of rural and urban elderly population. Whereas the time for leisure of elderly women in rural areas is much shorter than that of urban elderly women and rural elderly men spend more time to provide community services and help to other households. However, the percentage leisure time of rural elderly people for passive activities such as TV, radio, magazine etc. is longer than that of urban elderly people. We hope that our analysis data could be used for developing new policies and project to improve the life quality of rural elderly population.
