  • The purpose of this paper is to develop the Index of Balanced Life from the Korean life style. This paper presents How Koreans live for 24 hours a day, generally. The Index of Life Style is composed of necessary life, duty life and leisure life. Specifically, this paper considers moving time of activity between indexes of balanced life. We suggest that there is a difference among the characteristics, i.e., a sex, week, state of student and region that are explained by analyzing the exploratory data. Thereafter we obtain the statistical inference from each characteristic table.

  • Purpose: The purpose of this study was to describe life stress, life satisfaction, and adaptation of middle-aged women in the menopause period. Methods: The research design was to descriptive study using self-report questionnaires. Participants were 129 middle aged women living at A city. Data were collected from June 1 to June 30 and analyzed using SPSS/WIN program. Results: Significant differences in menopause adaptation were evident on the basis of spouse. There were significant differences in life satisfaction in terms of income. Life satisfaction was positively correlated to menopause period adaptation. Life stress was negatively correlated to menopause period adaptation. Life satisfaction and life stress were accounted for 36.2% in menopause period adaptation of middle-aged women. Conclusion: These results provide evidence of the effects of life stress and life satisfaction of menopause period adaptation.

  • Die life is generally estimated taking failure life and wear amount into consideration. In this study, the forging die life was investigated considering both of these two factors. The fatigue life prediction for the die was performed using the stress-life method, i.e. Goodman's and Gerber's equations. The Archard's wear model was used in the wear life simulation. These die life prediction techniques were applied to the die used in the forging process of the socket ball joint of a transportation system. A rigid-plastic finite element analysis for the die forging process of the socket ball was carried out and also the elastic stress analysis for the die set was performed in order to get basic data for the die fatigue life prediction. The wear volume of the die was measured using a 3-dimensional measurement apparatus. The simulation results were relatively in good agreement with the experimental measurements.
