To give additional assistance in education for family time use and time management a computer program based on the time-related theories was developed. For this purpose the study consisted of three main stages. First various theories of family time use time management strategies and household work time were investigated and the assumptions were suggested. Second the module for predicting family time use was designed and the program using the module was developed. Third to evaluate the program's benefits the program was used at introductory class of undergraduate course. As the results the sophisticated software program could be used as an educational instrument to help not only students but also individual and family member to become knowledgeable about managers of family time resource. furthermore this program could be useful for the educators and counselors to help individuals and households with time use problems.

As broadband access is evolving from digital subscriber lines to optical access networks, Ethernet passive optical networks (EPONs) are considered a promising solution for next generation broadband access. The point-to-multipoint topology of EPONs requires a time-division multiple access MAC protocol for upstream transmission. In this paper, we propose a new enhanced dynamic bandwidth allocation algorithm with fairness called EFDBA for multiple services over EPONs. The proposed algorithm is composed of a fairness counter controller and a fairness system buffer in the optical line terminal. The EFDBA algorithm with fairness can provide increased capability and efficient resource allocation in an EPON system. In the proposed EFDBA algorithm, the optical line termination allocates bandwidth to the optical network units in proportion to the fairness weighting counter number associated with their class and queue length. The proposed algorithm provides efficient resource utilization by reducing the unused remaining bandwidth made by idle state optical network units.

The water quality of Paldang reservoir now grades the third class water based on COD criterion, meaning that it is no longer suitable for drinking. This study attempted to estimate the economic value of water quality improvement in Paldang reservoir using CVM. The survey used payment card format to measure the willingness to pay of the questionnaire respondents for the improvement of water quality and also factors that affect the WTP. The survey showed that men rather than women, those had higher income and paid more water supply charges, those who lived in the area for a shorter period of time, those who do not use city water for drinking, had willingness to pay more. The WTP was estimated 4,952 to 5,497 won on a monthly average. The economic value of the improvement of the water quality of Paldang reservoir was estimated between 344.2~382.1 billion won on an annual basis.

The sample of this study was selected from the housewives’ living in Seoul who has credit cards. After class-analyzation of the sample, 523 out of 612 repondents were finally selected data. The data were analyzed by the statical methods such as frequency, mean, percentile, Factor Analysis, t-test, ANOVA, Duncan’s multiple range test, Person’s Correlation, and Multiple Regression Analysis through the SAS program package. The major findings of this study are as followers : First, housewives’ usage and management behavior of credit cards was a positive relationship between home management behavior pattern. Second, housewives’ cognition of credit cards showed a significant positive relationship with usage and management behavior of credit card. Third, the most influencial variables on housewives’usage and management behavior of credit cards were their value and home management behavior pattern.

The Purpose of this study were to examine the relationship between the motive of revolving credit card in the use of credit and financial management. The Samples were composed of 239 housewives in Seoul. The data were analized using frequency, percentages, and multiple regression. The major findings are summarized of follows : 1) Two-thirds of repondents used credit card over optimum standards. 2) Although the level of the motive of revolving credit in the use of credit card was not high, it was negative to financial management in the case of low-income household. 3) The contents of consumer education has to provide according to a different income class.

The purpose of this study is to describe and analyze the baby boomers' perception of and preparation for their successful aging. Seven women and three men were interviewed with the use of an unstructured questionnaire. Their perceptions of their likelihood of future successful aging were not negative, and were influenced by a range of considerations that included health, leisure, finance, volunteer services, family relationships, and elderly life without children's supports. They tried to prepare several kinds of sports, leisure activities, and volunteer services for their elderly life. However, their reasons for preparing these activities varied, and the background of their differences consisted of the family background, personal values, and experiences. Moreover, men and women responded differently to their personal experiences as they related to their elderly life. Women were likely to match their family relationship with their perception and preparation for successful aging, and men were not.
