Work environments have been changed with the advent of new technologies, such as computer technology. The newer technologies, the more changes in our work conditions. However, human cognitive limits can't keep up with the change of work environments. Mental workload has been an important factors in designing modem work environments such as human-computer interaction. Designing man-machine systems requires knowledge and evaluation of the human cognitive processes which control information flow workload. Futhermore, under an urgent situation, human operator may suffer the work stress, work error, and resultant deleterious work performance. To describe the work performance in the urgent work situations, with time stress and dynamic event occurence, a new concept of information density was introduced. For a series of experiments performed for this study, three independent variables(information amount system processing time, information density) were evaluated using such dependent variables as reaction time, number of error, and number of failure. The results of statistical anlysiss indicate that the amount of information effected on all of five dependent measure. Number of failure and number of secondary task score were effected by both amount of information and operational speed of system, but reaction time of secondary task were effected by both amount of information and information density.

The purpose of this study was to examine interactive effects of gender idelogies on the amount of household work time and the perception of fairness in household work by the couples. The data were collected from 100 couples in Seoul and 142 in Taejon. The Major findings were as follows: Interactive effects of gender idelogies had an important role in explaining household work time and the perception of fairness by husbands. For men holding more egalitarian gender idelogies who were married to women being more egalitarian tend to perform more hours of household work. And husbands who had traditional gender ideologies percept relatively fair to the couples' division of household work. It was approved that wives had a primary role in the division of household work.

Background: In industrial countries, home care of community dwelling elderly people is rapidly growing. Frequent injuries in home caregivers result from slips, trips, and falls (STFs). The current study tests attentional cognitive failure to mediate the association between work stressors and STFs. Methods: A sample of 125 home caregivers participated in a questionnaire study and reported work interruptions, unreasonable tasks, quality-threatening time pressure, conscientiousness, attentional cognitive failures, and STFs. Results: In structural equation modeling, the mediation model was shown to fit empirical data. Indirect paths with attentional cognitive failures as the link between work stressors and STF were all significant in bootstrapping tests. An alternative accident-prone person model, that suggests individual differences in conscientiousness to predict attentional cognitive failures that predict more frequent work stressors and STFs, showed no significant paths between work conditions and STFs. Conclusion: To prevent occupational injury, work should be redesigned to reduce work interruptions, unreasonable tasks, and quality-threatening time pressure in home care.

The rebar work is a labor intensive construction work with a high labor cost ratio. It is difficult to manage the productivity, construction time, and safety of rebar work. The problem of productivity decreased in rebar construction is due to a lack of workers according to the aged workers. Partial prefabrication rebar can be an alternative solution to productivity decreased in rebar work. The characteristic of partial prefabrication method is that time consuming component such as stirrup of beam assemble in factory and others assemble in site. Therefore, in this study, the time required for each rebar assembly method is measured and analyzed to confirm the possibility of productivity improvement.

PURPOSES : This study analyzes the available working time at work-zone on the Expressway in accordance to the new capacity manual. METHODS : Sensitivity analysis on variables were conducted to calculate the adjusted capacity at work-zone based on previous researches. RESULTS : The main factors which affect available working time at the work-zone were its capacity, number of lanes, terrain and lane width. Other factors have minimal effect on the available working time. Based on the analysis, a calendar of lane closures was suggested. CONCLUSIONS : A series of studies concluded that the capacity at work-zone in the new capacity manual reduced to 76-82% of the existing manual. As such, the available working time decreased. Furthermore, the factors affecting the available working time needs to be considered when making a plan to rehabilitate the distressed pavement.

This study investigates the balance between work and family, and the happiness of married working women who have preschool-aged children. Data were collected from 321 questionnaires that consisted of three parts: 1) basic demographic variables, 2) family-life variables, and 3) working-life variables. SPSS 21.0 was used for the statistical analysis. The variables that were identified to have a statistically significant impact on the balance between work and family were income, age of first child, time spent on housework and childcare on weekdays, time spent on housework on weekends, family-friendly service in the workplace and flexibility of work schedule. 2) The variables that were identified to have a statistically significant impact on happiness were age, income, time spent on housework on weekends, satisfaction with spouse's participation in housework and childcare, average working time, family-fiendly service in the workplace, flexibility of work schedule, and balance between work and family. The majority of the variables that influence balance between work and family, and happiness related to aspects of work, such as family-fiendly service, flexibility of work schedules, and average working time. The results also found that the load of housework and childcare on weekends is a heavy burden for working women. Further research needs to focus on developing the extending index of happiness including the measure of balance between work and life. In addition, further studies with more varied groups need to be conducted.

일-생활 균형에 대한 사회적 인식이 확산되면서, 이른바 '저녁이 있는 삶'을 위해 근로시간을 줄여야 한다는 주장이 제기되고 있다. 기존 연구들은 장시간 근로가 생활만족도를 낮추고 특정 범주의 생활시간에 부정적인 영향을 미치고 있음을 보여주었지만, 퇴근시간이 가지는 특정 시점으로서의 의미에는 주목하지 못하였다. 본 연구는 통계청의 2014년 생활시간자료를 이용하여, 어린 자녀를 둔 전일제 임금근로자 집단을 대상으로, 근로자의 퇴근시간과 일과 후의 범주별 생활시간의 관계를 살펴보았다. 퇴근시간 집단별 생활시간 구성의 차이를 분석한 결과, 이른 시간에 퇴근한 집단은 추가로 확보한 생활시간의 대부분을 가사와 돌봄에 사용하였고, 퇴근이 늦어진 근로자 집단에서는 일차적으로 가사와 적극적 여가시간을 줄이고, 퇴근이 더 늦어지면 추가로 돌봄과 소극적 여가 관련 시간을 줄이는 것으로 나타났다. 회귀분석 결과에서는 퇴근이 빠를수록 일과 후 생활에서 가사와 돌봄, 적극적 여가의 비중이 증가하였지만, 시간대에 따라서 야근 후 퇴근하는 집단에서는 소극적 여가가, 정시에 퇴근하는 집단에서는 돌봄이, 이른 시간에 퇴근하는 집단에서는 가사와 적극적 여가가 근로자의 퇴근시간과 더 분명한 부적관계를 보이는 것으로 나타났다. 퇴근시간을 앞당기는 조치는 가사와 돌봄에서의 젠더 격차 감소에 영향을 미치지만, 그 효과는 제한적이었다. 퇴근시간의 조정은 일-생활 균형의 달성에 도움이 될 수 있지만, 젠더 격차 등을 해결하기 위해서는 구조적인 제약을 줄이기 위한 노력이 병행될 필요가 있다.

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.

This study analysed the effect of mothers' work status on time use in child care and use of market child care services. There were two major questions: Do self-employed (and family worker without being paid) mothers have a flexible work schedule and so can they care her child(ren) well? If it is true, is the work status as self-employee related to non-market child care services? To answer these questions, 1,196 samples were selected from the Time Use Data of 1999, which had been administered by Korea National Statistical Office. Major results were as follows: First, a mother who is family workers without being paid made time to care children frequently more than wage earners. Second, according to regression analysis, mothers' work status was one of the important variables to explain child care activity frequency. Third, among categories of child caring ('physical caring', 'non-physical caring', and 'caring of the others'), mothers spent more frequently in 'caring of the others', and had higher probability to use market child care services. But the more frequently a mother made time in 'non-physical caring' for her child, the lower probability to choose market child care services. In conclusion, it was certain that self-employed mothers benefit from a flexible time schedule at work places. But the relationship of child care activity frequency with use of market child care services was inconsistent.
