Background: Tobacco use and quit attempts are two key indicators of the Global Adult Tobacco Survey (GATS) that assess quit attempts among current as well as former tobacco users. The relevant data have inherent policy implications for tobacco cessation programme evaluation. This study aimed to review the concepts of quit attempt assessment and quantifying invalid responses considering GATS-India data. Materials and Methods: GATS assessment of tobacco use and quit attempts were examined in the current literature. Two categories of invalid responses were identified by stratified analysis of the duration of last quit attempt among current users and duration of abstinence among former users. Category A included absolute invalid responses when time-frame of assessment of current tobacco use and less than former tobacco use were violated. Category B included responses that violated the unit of measurement of time. Results: Current daily use, current less than daily use and former use in GATS were imprecisely defined with overlapping of time-frame of assessment. Overall responses of 3,102 current smokers, 4,036 current smokeless users, 1,904 former smokers and 1,343 former smokeless users were analyzed to quantify invalid responses. Analysis indicated overall 21.2% (category A: 7.32%; category B: 17.7%) and 22.7% (category A: 8.05%; category B: 18.1%) invalid responses among current smokers and smokeless users respectively regarding their duration of last quit attempt. Similarly overall 6.62% (category A: 4.7%; category B: 2.3%) and 10.6% (category A: 8.6%; category B: 3.5%) invalid responses were identified among former smokers and smokeless users respectively regarding their duration of abstinence. Conclusions: High invalid responses for a single assessment are due to the imprecise definition of current use, former use and quit attempt; and failure to utilize opportunity of direct data entry interface use during the survey to validate responses instantly. Redefining tobacco use and quit attempts considering an appropriate timeframe would reduce invalid responses.

In order to verify the validity of the exhibition moethod in a science museum, this study undertakes a visitor follow-up survey, and clarifies the influence an exhibition method affect visitor's behavior, and its feature. The tracking research performed the visitor follow-up survey to family company children. The characteristic of the visitor's behavior by the exhibition method; Use frequency becomes low in order of 'Experience type' 'Participation type' 'Fixed type'. Experience type has tendencies, such as repetitive and continuing use, and use time was long. Otherwise use time of Fixed type was short. As a result, although the use frequency of Hands-on is high and its use time is longer than Hands-off, it turns out that is influenced according to factors, such as the exhibition method, presentation and the contents of exhibition.

This study is aimed to investigate the difference of leisure time use of elderly groups clustered with demographic factors and finally produce the leisure profile. A total 5392 time diaries, filled up by 65-years old and over in 2009 Time Use Survey, were analyzed by using descriptive statistics, correlation, cluster analysis, and ANOVA accompanied with the Scheffe's tests. The subjects could be clustered into 7 groups such as still working, work than leisure, hobby with friends, various leisure in a city, with religion and friendship, working and doing leisure in their spare time, and leisure in suburb based upon demographic factors such as age, gender, spouse, education, job, income and living area. The data also revealed that the clusters had different time use patterns in pursuing leisure. Overall, leisure in later life could be influenced by working status, and play an important role in filling their loss of job or spouse.

The purpose of this study was to investigate the differences in time use between Korean and American high school students. The data sources were the '2009 Time Use Survey' conducted by Korea National Statistical Office and the '2009 ATUS (American Time Use Survey)' conducted by Labor Statistics Division in the U.S.. 1,734 Korean diaries (1,311 on weekdays and 423 on Sundays) and 321 American diaries (208 on weekdays and 113 on Sundays) from high school students of 15 to 18 years of age were analyzed. Descriptive statistics and t-test were used for the statistical analysis. The time use patterns of Korean students on weekdays and Sundays were different than those of their American counterparts. On weekdays and Sundays, the sleeping time of Korean students was 2 hours less than the time of their American counterparts. Koreans studied more, nearly double the time of their American counterparts on weekdays and five times more on Sundays. The study-oriented time allocation of Korean students resulted in less leisure time than the American students. Korean students spent their leisure time of more than 30 minutes participating in social activities, media, and hobbies, and their time allocation to volunteer work and religious activities were nil. On Sundays, the time for studying by Korean students was more than five times longer than that spending by their American counterparts. Koreans used their leisure time of 6 hours and 47 minutes mainly for media, hobbies and social activities. The participation rate of volunteering by Korean students was only 0.5%, though it was 31.0% for the Americans. For a study-life balance for Korean students, it was recommended that trends toward time management and social policy should increase the time allocation to sleeping, housework, work, sports, and volunteering and decrease the time use in studying and hobbies.

The purpose of this study was to explore a typology of time allocation, investigate determinants of time allocation types, and analyze differences in time use satisfaction by the types of time use of the elderly. The data source for this research was the 2009 Time Use Survey conducted by the Korea National Statistical office (KNSO). The 4,699 time diaries (3,552 for weekday, 1,147 for Sunday) completed by the elderly over the age of 60 were analyzed using mean, standard deviation, chi-square, cluster analysis, ANOVA analysis, Duncan test, and multinomial logistic regression analysis. Time allocation of the elderly was classified into four types: personal care oriented, work oriented, leisure oriented, and balanced type. Gender, age, education, employment status, income, and the presence of spouse were identified as determinants for each type. According to the types of time allocation, time use satisfaction was different on week days.

The purpose of this study was to investigate the changes in the use of mobile phones due to COVID-19. The subjects of this study were those who lived in Jeju City and used their own mobile phone for more than 2 years, and were included in adult men and women aged 15 to 80 years old. The purpose of this study was explained and a questionnaire survey was conducted on 156 people who agreed. The survey period lasted from June 15 to July 4, 2020. As a result, the daily use time and function of the mobile phone, which were used more than before the occurrence of COVID-19, increased. This was a statistically significant trend (p<0.001) with increasing trend after COVID-19 in all age groups. In addition, in the mobile phone function, all age groups used more 'KakaoTalk' than 'call', but it was found that only the group with less than 1 hour of daily using time used the call function a lot.
