This study was aimed at exploring gender differences in time use and time famine between single-parent families. Data were obtained from the time use surveys, that were conducted by the Korea National Statistical Office in 2014. A total of 500 time diaries (168 from fathers, 332 from mothers) from single-parents aged between 20 and 59 were analyzed. Descriptive statistics, chi-square test, and t-test were used for the statistical analyses. Results indicated that the single-parent families exhibit gender differences in time use and subjective time famine. The single-mothers spend a significantly longer amount of time on housework and less time on leisure than do the single-fathers. The single fathers and mothers also differ in time use and time famine according to employment status and working days on/off.

In this study, I analyzed single people time use and leisure behavior. I have compared patterns of time use of the single people who completed a survey for this study with the data from Time Use Survey(Korea National Statistics office, 1999). The survey participants included 160 single people who were thirty- to forty-years-old and who were living alone. The data from the Time Use Survey by NSO contained 2,004 married people cases and 30,155 unmarried individuals cases. The major findings are as follows: First, the single people who participated in this study were not especially anti-marriage; they simply have not been married yet and were living in a one-person household. Second, single people spent more time at work and less time for leisure and socializing than two comparative groups. Third, single people spent more time for household labor than other groups, and the only exception was the married female group. There was no gender difference in the time spent at household work Finally, single people tended to spend their leisure time with passive activities such as reading a newspaper or a magazine, watching television, and listening to the radio.

The purposes of this study were to examine the time use on weekdays and weekends by the time amount of each activities and compare time amounts of single parent with that of two parents family. So two methods were applied, one was secondary data analysis ,the other was deep-interview. The major findings of analysis of time use were as follows; 1) Mothers in single parent family used significantly less time amount of household labor and family care than them in two parent family 2) Fathers in single parent family used significantly more time amount of household labor but used significantly less time amounts of family care than them in two parent family And 3) Mothers in single parent family used significantly more time amounts of household labor and family care than fathers in single parent family. The results of deep-interview were as follows; roughly the amounts of household labor time, family care time, leisure time were of little quantity and absence of spouse, family size, family life cycle stage, economic condition, sex role identity, psychological factor maybe seemed important.

This study grasps the living condition of Single-Parent-Family, and compares Single-Parent-Family with Dual-Parent-Family to analyze necessary factors to enjoy the happier life. The data from '2009 the Korean Time Use Survey' and '2010 the National Survey of Korean Families(NSKF)' are used for this study. ANOVA, Duncan test, Correlation Analysis(SPSS for windows, Ver. 18.0) are used for statistical method. Here are the results of this study. First, distribution of living-time-usage of the Single-Parent-Family is different from that of Dual-Parent-Family. Second, the difference in the amount of leisure time, time distribution, and the content of activity was observed based on the gender of Single-Parent-Family. Third, there is a difference in family leisure activity time among Dual-Parent-Family, Mother-Single-Parent-Family, and Father-Single-Parent-Family in holidays. Fourth, there is a clear difference between Dual-Parent-Family and Single-Parent-Family, after looking at life satisfaction degree in work-family-leisure life experience.

This study analyzed time allocation in unmarried single household. It examined meal activities and leisure by gender and employment status using the 2014 time-use survey data of 1,664 cases provided by Statistics Korea. Descriptive statistics, a paired t-test, and regression were conducted using the SPSS 24 program. The results showed that the total time for meal activities in unmarried single households was 125 minutes. Most meal activities consisted of eating activities, and the meal preparation time was about 19 minutes. Females spent much longer time in meal preparation than males. Leisure time was 285 minutes, and the longest time spent of leisure activities was spent using medias. Males' total leisure time was longer than females' total leisure time. Finally, employed individuals spent much longer periods of time in leisure than unemployed individuals. All the results showed differences between genders and employment status.

The study is attempted to help double-income families use resources efficiently and rationally by analyzing The Time Use each of working women and housewives having preschool children based on the data of The Time Use survey carried out in 2004 and promote understandings on their quality of life, lifestyle and family welfare. To this end, the study analyzes the actual The Time Use of double-income families haying preschool children. The findings of the study are as follows: First, according to the comparison of The Time Use between double-income families and single-income families in 1999 and 2004, there is no significant difference in husbands' participation time in family management or family care between 1999 and 2004. Second, according to the comparison of The Time Use between double-income families and single-income families depending on the presence or non-presence of preschool children, families haying preschool children spent much more hours in family care than families without preschool children. Third, according to the comparison of the weekend schedule between double-income families and single-income families, it is found that working women work much more than housewives not only on weekdays but also on weekends and in particular, it is found that working women having preschool children work 2 hours longer than housewives.

The concept of reliability has been applied to the topology optimization based on a reliability index approach or a performance measure approach. Since these approaches, called double-loop single vector approach, require the nested optimization problem to obtain the most probable point in the probabilistic design domain, the time for the entire process makes the practical use infeasible. In this work, new reliability-based topology optimization method is proposed by utilizing single-loop single-vector approach, which approximates searching the most probable point analytically, to reduce the time cost. The results of design examples show that the proposed method provides efficiency curtailing the time for the optimization process and accuracy satisfying the specified reliability.

The purpose of this study was to identify characteristics of space usage patterns by types of elderly households(single or couple). For the study, 74 elders who were older than 65 were selected and their living behaviors at their home during a day (24 hours) were analyzed. Respondents were classified into 6 types based on a combination of their household type, income level and health status. The results showed that the elderly residents tended to live a well-regulated life, however, each type had unique time and space use pattern. For example, the more the elder residents were healthy, the more they used many rooms. Frail elderly residents spent most of the day in their bedroom. Also, if they had a spouse, each one tended to use a separate private room for his or her daily life whether they shared a bedroom or not.

This paper addresses the problem of single-channel speech separation to extract the speech signal uttered by the speaker of interest from a mixture of speech signals. We propose to apply time-frequency smoothing to the existing statistical single-channel speech separation algorithms: The soft mask and the minimum-mean-square-error (MMSE) algorithms. In the proposed method, we use the two smoothing later. One is the uniform mask filter whose filter length is uniform at the time-Sequency domain, and the other is the met-scale filter whose filter length is met-scaled at the time domain. In our speech separation experiments, the uniform mask filter improves speaker-to-interference ratio (SIR) by 2.1dB and 1dB for the soft mask algorithm and the MMSE algorithm, respectively, whereas the mel-scale filter achieves 1.1dB and 0.8dB for the same algorithms.
