This study conducted a questionnaire survey of the current use status of central kitchen products on 198 dietitians and cooks working at a catering center of a company affiliated with group S in order to investigate the use state of the central kitchen products in catering. The largest groups of respondents answered that they use the central kitchen products once two to four days. As a reason to use it, the largest group answered that they used it because of the ease of preparation. In addition, the results show that the subjects often use sauce and processed vegetables among the central kitchen products. This study investigated the efficiency of cooking, hygiene and safety management of the central kitchen products. The results show that they have a large effect on shortening the cooking time. The quality control and service efficiency of the central kitchen products showed a positive reaction to the menu diversification and excellent quality but a negative reaction to the nutritious superiority. The operating cost efficiency of the central kitchen products generally showed a negative reaction except for the reducing effect of waste rate. As an improvement of the central kitchen products, the survey shows that the reduction in price and quality progress should be most urgently improved. Based on these results, the introduction of the central kitchen products into to the catering enables to standardize mass production, improve the taste and quality, cook without professional chefs and produce productivity increasing effect in the catering by the time shortening effect.

This study analyzed the composition of the time use and childcare time use of working mothers and fathers of Generations X and Y, differences between generations, differences between mothers and fathers, and factors affecting childcare time. We analyzed the lifetimes of working parents of preschool children(n=2,287) using Statistics Korea's Time Use Survey for 2014 and 2019. The main results are as follows: First, when comparing the lifetimes of Generations X and Y, in 2014, Generation Y mothers had longer commuted times, whereas for fathers, there was no difference between generations. Second, comparing the time use of Generations X and Y, regardless of the survey period, Generation Y mothers had longer sleep times than their counterparts, while Generation Y fathers had longer time in sleep, home management, and childcare than their counterparts. Third, in analyzing the factors affecting parents' childcare time for mothers of both generations, the less sleep times, mealtimes, working times, commuted times, home management times, and leisure times, the longer the childcare times. In the case of fathers, for Generations X and Y, the less sleep times, mealtimes, market work times, commuted times, and leisure times, the more childcare times. However, in Generation X fathers, home management time and the gender role attitude affect childcare time. While the generation gap was not clear for mothers, it was confirmed for fathers. Therefore, it was proposed not only gender differences but also generational characteristics should be taken into account to provide implications for child care policies, especially for fathers, in community care support systems incluing education and counseling programs.

The purpose of this study was to investigate the standardization of daily average smartphone use time among adolescents. The data were analyzed using the data from Korea youth risk behavior web-based survey of 2017, and the total number of students analyzed was 54,603. Frequency analysis, independent t test, Pearson correlation analysis, and one-way ANOVA were used for statistical analysis. As a result, the correlation coefficient between smartphone use time, age, and grade was very low (r =.025~.039). There was no significant difference in the usage of smartphone between middle and high school students(p>.05). Time of smartphone use was significantly higher in middle school students as the grade increased(p<.05). In high school students, second-year students had significantly more smartphone usage than first and third grade students(p<.05). The researchers described 54603 adolescents' average(minute) daily smartphone usage about sex(male, female), period of use(weekday, weekend), school(middle school, high school), and grade(first, second, third) as a 7th quartile. We suggest that the standard value of smartphone use time can be used as a basis for the physical and mental health management in adolescents. It is necessary to present a standard value that can prove the future overuse of smartphone.

This study aims to clarify the difference between scores for time management practice and the self-evaluation of time use according to time rules in families. This study used data obtained from the first survey on after-school activities in 2008, conducted by the Benesse Educational Research and Development Institute in Japan. The study sample consists of 3,372 middle school students. First, scores for independence and planning were highest in third grade, yet the score for regularity was also lowest in third grade. There will be different lifestyles even among middle school students of the same grade, so it is necessary to consider their characteristics and family rules. Second, the scores for independence, regularity and planning were lowest in groups whose families had rules about time (time rules for curfew, time rules for watching television, time rules for playing games), but in which those rules were not kept. These results were similar for both boys and girls and show that it is more important keep rules rather than to make rules.

Today many owners of Web sites are looking to user's satisfaction survey as a key means of measuring the usability of a Web site. While it is preferred for it simplicity and ease of use, this survey method is not without potential risks. This paper focuses on showing that the existing practice of questionnaire-based usability measurement is subject to human recall errors, and that such flaws can be reduced when the questionnaire survey is followed by the users hands-on experience of the site. An empirical study was conducted, and the results indicate that the above speculation holds true. Even if respondents felt highly confident about their responses on a recall survey, a hands-on experience with a focal Web site increased the extent to which the respondents were satisfied with the shopping mall site. This indicates that a user's perception of the quality of a Web site may be distorted or lost as time goes by. In addition, the findings have shown that the use of the verbal protocol analysis method can reveal critical information that can help track the root causes of Web site usability problems, thereby helping to develop site enhancement strategies. The paper concludes with directions for future research.

Based on the theory of use and satisfaction, this study investigated the strength of TikTok usage motives (entertainment, information-seeking, interaction, self-expression, and escape) and the effect of each motive on users' adherence (frequency of use, time of use). investigated. After conducting a survey on TikTok Chinese users and removing insincere answers, 101 survey results were analyzed. The analysis results are as follows: First, the intensity of motivation for using TikTok was in the following order: entertainment-seeking, information-seeking, interaction, self-expression, and escape. Among them, the motives of pursuit of entertainment and escape were higher in females than in males. And the motives of pursuit of entertainment and escape were higher in the case of women than in the case of men. Second, as a result of analyzing the effect on user adhesion, the influence of the users' entertainment pursuit motive, interaction motive, and escape motive was significant for the frequency of use, and the influence of interaction was high. Third, the influence of entertainment-seeking motives and escape motives was found to be significant for use time. This means that users often use TikTok for entertainment, interaction, and escapism, and longer TikTok usage time for entertainment or escapism.

This paper gives special attention to the changes of time use patterns of the German population for eating and drinking as well as for household work. It especially examines the changes in time use for meals eaten at home and away from home as well as the division of labour for nutrition provision activities between men and women. The presented results originated from two time budget surveys conducted in Germany in 1991/92 and 2001/02. In a secondary analysis time use patterns for eating and drinking and nutrition provision activities were examined on a base of a representative sample of 12600 private households. Surprisingly the amount of time spent on eating and drinking increased over the period. More Germans ate away from home at least once a day, whereas meals at home were still dominant. Moreover comparisons over time revealed that the share in household and food provisioning work has narrowed between men and women, especially in households with both partners being employed. Overall the analysis shows that time use data allow general statements regarding the amount and changes of time spent on daily eating, household work and especially food provision activities. The extent of women's employment has shown to be most decisive for an equal division of household work between gender. To be able to better interpret the results and to understand the consequences for family life, it is necessary to complement time use data with qualitative interviews to gain comprehensive insight into peoples nutrition goals, motives and barriers of action.

This study explored a typology (or time allocation), investigated personal and work characteristic differences among time allocation types, and identified determinants of time allocation types of married working women with a preschool child. The data source for this research was the 2014 Time Use Survey conducted by Statistics Korea. We analyzed 368 time diaries (184 for weekdays and 184 for weekends) using frequency, mean, cluster analysis, chisquare, analysis of variance (ANOVA), Duncan's test, and multinomial logistic analysis. The results of this research are as follows. Time allocation of married working women with a preschool child was classified into three different types of 'work-centered,' 'work-family balanced,' and 'family-centered.' The work-centered type accounted for 14.7% of total respondents, and compared with other types, this type of people spent more time working, and less time doing house-work, caring for family, and having leisure. The work-family balanced type represents more than half of the total, and spend more time working on weekdays and house-working, having leisure on weekends. The family-centered type represents 28.8%, and spends most of the time doing house-work and caring for family on both weekdays and weekends. Occupation, employment status, monthly income, and weekly hours of work were different for each type. Occupation, employment status, perception of lack of time, health condition, and weekly hours of work were identified as determinants for each type.
