The purpose of this study is to investigate the relationship to the life-style, perceived time pressure and time management strategies of married women. The research issues are as follow : 1. How are Life-styles influence to the perceived time pressure according to employment status of marraged women? 2. How are life-styles influence to the time manegement strategies according to employment status of marraged women? 3. How much are the effect of life-style, perceived time pressure and the rest of variable on the time management strategies of marraged women? For the purpose of this study, 585 questionnaire were distributed to marraged women living in pusan. The data were analyzed by statistical methods such as Pearson's correlation, percentage, factor analysis, and regression analysis. The significant results are as follow : 1. According to the employment status, there were several differences among those life-styles which are influencing to the perceived time pressure. 2. According to the employment status, there were differences among those life-styles which are influencing to the time management strategies. 3. Independent variables about the time management strategies of married women showed life-style(B=.46), age(B=-.18), income(B=.15), perceived time pressure(B=.12). education level(B=.07). The results of this study can be attributed to develop the efficient strategy of reducing perceived time pressure of marraged women.

Optimal pricing research in general has been focused on profit maximizing strategy under the given product life-time T. Here we have tried to study the effect of uncertain product life-time on dynamic optimal pricing strategy. In reality, the life-time of product is more likely to be uncertain and not known as well. In terms of approximating the model to the concerned reality, so-called model validity, it seems to be more desirable to consider the uncertainty of product life-time into the optimal pricing strategy model, For this purpose, we tried two different approaches. One is to consider diverse product life-time probability functions under fixed life-time T. In this case, we might have the same product life-time as the previous study, but the process could be different in the expectation of product's discontinuity. The other is that life-time itself is not determined and thus it is the situation in which we can only decide optimal price on incremental basis. The former is the situation in which although we got some strong guess on life-time of a certain product, the pattern of expected life-time probability could be different. The question is what could be optimal pricing strategies on such different product life-time situations. But since in the latter, we don't assume any idea on the life-time of product. proper optimal pricing could be derived only from the past prices and diffusion information. While the latter seems to be safer in the aspect of model assumption, the former could be more realistic because we might have more or less a prior knowledge on the product life-time itself.

This study explores the daily life of Korean designers in New York. We use in-depth interviews within the daily lives of participants to first reveal the time structure and meaning of everyday life. In this everyday time frame, this study reveals the content and meaning of life in New York, which is especially useful for fashion majors. Participants were 11 single Korean women around 30 years old working as designers in New York. Data was collected from Manhattan, New York, from November 2013 to February 2014 through the use of in-depth interviews and participant observation. Data collected daily life information on time usage, money, and energy that is first summarized into 229 meaning units. In the following, 55 central meanings were derived from stories common to behaviors for study participants and 19 subcategories were compressed into academic language. Finally, the generalized categories are divided into six categories of study life, work life, future life, family life, leisure life and fashion life. As a result of the first study, the daily time structure consisted of customary public time and personal repeat time. Second, the customary public time categories included the studying for 'Beginning to jump again to the best', 'Now working as a designer in New York', and future life expecting 'Future growing as a career woman'. Repeated personal time categories include family life: 'A single life of a lonely and poor gentile', leisure life: 'Healing life that is supported by abundant advanced culture', and fashion life: 'New York fashion life coexist with harmony'. Third, work was the center of everyday life for study participants versus fashion and leisure that were central to everyday life when not working.

A partial discharge(PD) measurement is a very effective method to assess the insulation condition of high-voltage machines. It is necessary that the life time of the on-line PD measurement sensor is assessed. Therefore, the electrical life time assessment method of ceramic element was reviewed in order to estimate the life time of the on-line PD measurement sensor. The samples were prepared according to the reviewed method and were tested at 8kV, 9kV and 10kV. Based on the obtained results, the life time constant is shown above 59. Also, it is assumed that the estimated life time constant can be used to anticipate the life time and to assess the conformity of the on-line PD measurement sensor.

This study aims at studying dual-earner couple's household work time and life satisfaction in modern times. To reach this goal, dual-earner couple's variable of society and population, income for working hours, attitude of sex's role and working hours time were classified as individual variable of study model. In the end of 2000, positive analysis was completed through dual-earner couples' frequencies, percentage, means, paired-samples T Test, one-way ANOVA, duncan test, multiple regression and path analysis to 112 Korean couples in 'Research material for comparative analysis of family's time use in Korea and in the United States' performed by Lee, Ki-young, along with 3 person in the end of 2000. The time of household work performance at home at this stage is about 30 hours. 90% of 30 hours was given by housewife who was working for another job. In the aspect of dual-earner couple's life satisfaction, the life satisfaction is a little over the level of average. In variables couple's life satisfaction, wife's life satisfaction was additionally influenced by variable of wife's profession, age difference of couple, wife's household work time husband's household work time and wife's sex-role attitudes in oder. Husband's life satisfaction was perfectly influenced by his level of education, his household work time and wife's sex-role attitudes.

This study aims to identify causal variables by examining the mutual influences of community consciousness and life satisfaction. We used some data of KCYPS. A longitudinal study of 1952 adolescents selected as a sample was conducted using the Aautoregressive crossover delay model. The results of this study are as follows: First, it showed that life satisfaction is consistently affecting the later life satisfaction with the passage of time. Second, community consciousness showed that the previous community consciousness has a constant influence on the subsequent community consciousness as time passes. Third, the effect of previous life satisfaction on community consciousness was significant. Therefore, the cross-delay effect of life satisfaction on community awareness was stable with time. In other words, life satisfaction level was a causal variable that takes precedence over community consciousness, and the higher the life satisfaction of the previous time, the higher the level of community consciousness in the future. Fourth, the cross-delay effect of community consciousness on life satisfaction was not significant because community consciousness at previous time had no meaningful effect on life satisfaction at later time, so consciousness of community at previous time affects life satisfaction. This study provided some implications basing on this results.

The purposes of this are to figure out the amounts of leisure time of full-time homemakers and to find out leisure time factors contributed to raise the quality of life. The major findings are the followings: 1) Full-time homemakers spend 353 minutes(5.9 hours) on the average per day on the leisure. Time for active leisure(creative activities, sports activities, spectator events, going to the party, and so on) is 70 minutes, while that for passive leisure(watching TV. listening to the radio, reading newspapers. magazines. Books, chating, relaxing, card playing) is 283 minutes(4.7 hours). The passive leisure is the main type of spending leisure time. 2) The total leisure time of wives is significantly related to SES factors. The higher the wives age and education, the family income, and the age of the latest child, the more the wives total leisure time. But the more the family numbers, and the child numbers, the lower the leisure time. Active leisure time is highly rela ed to family income, while passive leisure time is considerably family composition. 3) The wives are mostly satisfied with their lives. The wives perceptions of the quality of life is related to wives's education, house type, and family income. 4) The wives total leisure time is not related to the quality of life. There is a positive correlation between active leisure time and the quality of life, while a negative relationship is between passive leisure time and the perception of the quality of life. 5) In analysis of causal model, it appears that family income and active leisure time of wives directly affect the perceived quality of life. The more the family income and active leisure time, the higher the quality of life. it is implicated for wives to take and active attitude and to reduce, if possible, passive leisure time and to increase active leisure time.

This study focuses on time management behavior, which differs in (1) the characteristics of schools and (2) the experience of education about time management. Also, this study examines the effect of time management behavior on life satisfaction of vocational and non-vocational high school students, and also those who attend life-long education schools. The study sample consists of 367 teen-age high school students in Seoul. The result of this study demonstrates that the experience of education about time management has a great effect on time management behavior. Students experiencing education about time management have higher scores in time management behavior than those who lack such experience. It also shows a close relationship between time management behavior and life satisfaction in non-vocational high school students and those attending life-long education schools.
