본 연구는 "2014 생활시간조사" 데이터를 이용하여 부부의 시간배분 결정요인에 대하여 분석하였다. 분석 결과, 대체로 남편의 육아 및 가사시간은 아내에 비하여 매우 적은 것으로 나타났으며, 아내의 임금이 높고, 어린 자녀가 있을 경우 남편의 육아 및 가사시간이 증가하였다. 아내 시간배분의 경우는 주로 배우자(남편)의 임금에 많은 영향을 받는 것으로 나타났는데, 남편의 임금이 증가할수록 아내의 노동시간은 감소하며, 가사시간은 증가하는 것으로 나타났다. 그러나 육아시간은 아내와 남편 모두의 임금에 영향을 받지 않는 것으로 나타났다. 반면 아내의 임금이 증가할 경우에 남편의 육아 가사시간이 같이 증가하는 경향이 있었다. 시간배분의 상관관계에서 아내의 노동시간과 남편의 가사시간은 보완관계에 있었으나, 아내와 남편의 가사시간은 대체관계에 있는 것으로 나타났다. 이것은 곧 아내가 일을 많이 하여 생긴 가사일의 부족분을 남편이 채우게 되지만, 집안일을 부부의 누군가가 한다면 다른 한 쪽은 안하게 된다는 것을 의미한다. 그러나 주말에는 이러한 관계가 크게 변하게 되는 것을 발견할 수 있었다.

This study compared the pattern of couples' time-use in rural areas. Wives' and husbands' time spent in household work, leisure, and agricultural labor were compared. In addition, this study examined what factors determine the amount of time of couples spent in such activities. According to the results, in general, the pattern of couple's time-use in rural area was different. Regarding the pattern of time-use, three major results could be mentioned. First of all, husband in rural area spent most agricultural labour time in busy farming season. And then husband spent much time in leisure activities and wife spent in household work. Second, wife spent more time in inactive leisure and husband spent more time in active leisure. Third, husband in rural area spent less time in household work. In particular. they spent less time in female-typed work than male-typed work. To examine what factors determine the extent of time spent in such activities, three theories were employed and tested. According to the results, the models employed in this study were realistic in explaining the amount of time of couple in rural area, and more adjustable wife than husband. In conclusion, a combination of the multidimensional theoretical perspectives used in this study helpfully explains the variation in the amount of time-use of couple in rural area.

This study was aimed at exploring the differences in time use and time famine among college students ages 18 to 29, with a focus on gender and employment status, and to investigate the determinants of time famine. Data were from the 2014 Time Use Survey by the Korea National Statistical Office. Descriptive statistics, chi-square test, t-test, and logistic regression were used for the statistical analyses. The major findings are as follows. First, the employed spend significantly more time on work and less time studying than the unemployed, and females spend significantly more time on household work and less time on leisure than males. Second, employed students had higher levels of time famine than unemployed students. Third, irrespective of employment status, the education level of students' parents was identified as a determinant of time famine. Other determinants of time famine were age, job, work, and study time for employed students and gender, income, household work, and leisure time for unemployed students.

The main purpose of this study is to investigate factors that influence sleep duration and sleep time poverty in terms of family characteristics, child characteristics, and time use. A series of data analyses were conducted on children's time use in two-parent families based on the 2013 Korean Children and Youth Panel Survey. One major finding is that children's sleep duration and the probability of having a sleep time poverty are related to their mothers' job classifications. The factors influencing the duration of sleep time and the sleep time poverty are similar in terms of family characteristics and children's time use. The mother's job classification, family income, number of younger siblings, number of older siblings, children's private tutoring hours, computer game hours, and TV hours are statistically significant factors affecting the duration of sleep time and the probability of having a sleep time poverty. However, the factor with greatest influence on sleep time duration is private tutoring hours and the factor most affecting sleep time poverty is computer game hours. The mother's job classification is a relatively powerful determinant for predicting her children's sleep duration and sleep time poverty.

The purpose of this study is to evaluate the roles of expected self-control and expected self-control results in explaining adolescents' Internet addiction. In the study model, expectations of self-control and self-control results directly determine Internet addiction and Internet use time meditates the impacts of expectations of self-control and self-control results on Internet addiction. The study subjects are 1,080 middle and high school students in Busan. Stratified cluster sampling is applied by school type and school year. The response rate is 96%(l,037cases). This study develops the scales of expected self-control and expected self-control results. The scales of Internet addiction are devised by using the concept of functional dependency such as salience, withdrawal symptoms, mood modification, tolerance, relapse, and conflict. For verifying the study model, path analysis and multiple regression models are applied for identifying path significants and evaluating confounding effects of control variables, respectively. Moreover, multi partial F-test is performed for selecting the best regression model. Expected self-control is a significant determinant of Internet addiction and Internet use time that also significantly explains Internet addiction. The total effect of expected self-control towards Internet addiction is -.95. The total effect is comprised with the direct effect (-.71) and the indirect effect(-.24). In this result, the direct effect refers a curative effect since expected self-control directly reduces the level of Internet addiction, and the indirect effect refers a preventive effect because self-control can reduce time of Internet use that is a direct determinant of Internet addiction. In the test of the confounding effects of control variables, there are no confounding effects in the models of multiple regression. It implies a robustness of the study model as regards control variables. In conclusion, improving adolescents' expected self-control can control Internet addiction level. This finding implies that a health promotion program for improving expected self-control can be a cost effective method compared to other approaches.

This study explores how unmarried workers use their leisure time according to the 2009 Korean Time Use Survey. The purposes of this study are: 1) to investigate leisure time as it relates to leisure participation rates and leisure participation time and 2) to analyze the effect of socio-demographic variables on leisure time and leisure participation by unmarried workers. The following is a summary of the major findings. First, leisure participation differed with variations in leisure activities. Unmarried workers participated in media contact, human relations activities, and hobby activities more than other activities. Participation in learning activities was higher on weekdays than on Sunday. Men participated in sports and outdoor activities more than women on Sundays. The participation rate of media contact was the highest, while the participation rate of volunteer activities was the lowest. Second, influencing factors on leisure time included gender, age, monthly income, and gender role attitudes when work time was controlled. For example, unmarried workers with egalitarian attitudes spent less leisure time. Third, gender was the strongest determinant of leisure participation. The probability of women's leisure participation was higher than men except in regards to sports and outdoor activities, and hobby activities.

The wide spread of smartphones and the growth of the number of internet users are reshaping the SNS (Social Network Service). Merging into other service areas and creating new business models with high profits, SNS is no more a service simply providing personal connections. Now SNS has positioned itself as a service platform. SNG (Social Network Game) is a new outcome utilizing SNS as a game platform and showing a rapid growth rate in a short period of time. The number of SNG users is expected to increase steadily. In this study, we examine whether SNG user motivations lead to flow experience and future intention to use. For that purpose, we conducted a survey with smartphone users. The results indicate that flow experience functions as a mediator and user motivations indirectly affect intention to use through flow experience. This paper concludes with discussions on findings and suggestions for future research.

This note presents a an indirect adaptive control scheme for first-order continuous-time systems. The estimated plant model is controllable and then the adaptive scheme is free from singularities. The singularities are avoided through a modification of the estimated plant parameter vector so that its associated Sylvester matrix is guaranteed to be nonsingular. That properties is achieved by ensuring that the absolute value of its determinant does not lie below a positive threshold. A modification scheme based on the achievement of a modified diagonally dominant Sylvester matrix of the parameter estimates is also given as an alternative method. This diagonal dominance is achieved through estimates modification as a way to guarantee the controllability of the modified estimated model when a controllability measure of the ‘a priori’ estimated model fails. In both schemes, the use of a hysteresis switching function for the modification of the estimates is not required to ensure the nonsingularity of the Sylvester matrix of the estimates.

The purpose of this study is to examine determinant to purchase decisions by consumers using the home shopping of cable TV. For the purpose accomplishment, this researcher surveyed demographic characteristics of cable TV users to determine what differences in types of goods purchased by the users were made in accordance with the characteristics. Findings from the study may be reflected in bisiness policies seeking the fulfillment of consumer needs, and be used as a basic information for the establishment of consumer policies pursuing increased qualities of consumption life by providing information on goods shown through the of home shopping on cable TV. The result of the study can be summarized as follow. First, purchased goods were greatly different in their types depending on demographic characteristics of consumers such as gender, marital status, age, educational backgrounds, income and jobs. Second, experiential characteristics of cable TV users including holding or non-holding credit cards, main channels used, the main time of watching cable TV and purchase frequency per year contributed to differences in types of purchased goods. Third, factors influencing purchase decisions were somewhat different according to types of goods. However, previous purchase experiences were most influential irrespective of the types. The result as described so far suggests that previous purchase experiences by consumers raised their chances of repurchase by removing possible risks perceived by consumers. Based on the result as above, the researcher would make the following conclusion. First. companies operating the of home shopping on cable TV should increase satisfaction by consumers by providing reliable goods and information to them. In this sense, those companies need to establish marketing strategies that vary according to demographic characteristics of consumers and at the same time provide product information necessary for fulfilling consumers' requirements. Second, consumers should be moderate in the use of credit cards to avoid unplanned purchases via home shopping on cable TV and have some knowledge to solve problems related to goods and to the use of credit cards.
