The purpose of this study is to identify sevral variables which were assumed to have relationships with the role conflict and marital satisfaction of married working women, and to examine the relationship of the role conflict and marital satisfaction of married working women in Korea. The data for this study was obtained from the survey of the 262 married working women who reside in the city of Seoul employing questionnaire method. Such methods as frequency, percentile, factor analysis, analysis of variance (t-test, F-test), and Pearson's correlation were used for the statistical analysis for this study. The major findings of this study can be summarized as follows; 1) The role conflict level of married working women was related to variables such as age, the number of children, work time, husband's support, job satisfaction, motivation to work outside the home. 2) The overall marital satisfaction was relatively high when they have two children and the presence of household work help. Futhermore, ut was found that marital satisfaction considerably high when husband's support and job satisfaction was highly accorded. 3) The role conflict and marital satisfaction of married working women were significantly negatively correlated.

The Purpose of this study is to search a tendency of financial disagreement and to identify the variables influencing on financial disagreement of husbands and wives. for this purpose, reviewing literatures and empirical research were conducted. The sample was selected from the husbands and wives living in Masan, Changwon and Jinhae. Among 336 respondents. 111 husbands and 225 wives were finally selected as datum sources. The data were analyzed by the statistical method such as frequency distribution percentile ,ANOVA. Peason's correlation and Regression analysis. The main results were as follows; 1) Most husbands and wives showed th high level of financial disagreements. 2) As for the related variables, socio-demographic and psychological variables such as husband's education. family income, communication and financial management behavior had turned out to be significant on the financial disagreement of wives. As for the husband's financial disagreement, husband's education and family income had a significant influence. 3) There were negative correlation between the financial management behavior and the financial disagreement of husbands and wives(r=-0.22. -0.35). 4) the family characteristics which were the best predictors of financial disagreement included; family income, financial management behaviro of husbands and wives.

The purpose of this study is to extract typical body shape of Korean VDT workers based on the three-dimensional Korean shape data and recommendation supported by Korea Occupational Safety & Health Agency during VDT task. Desirable desk heights and chair heights for the selection of the VDT working posture is proposed by analyzing moment, compression and joint shear for lumbar and spine of Korean adult(male and female). The desirable heights for desk and chair can be selected by the least load method during VDT tasks. In the current work the figures of Korean 50th percentile offered by CATIA-HUMAN are used as the average body type of the grown-ups and this research is accomplished with the recommended size of all working attitude such as the height of a monitor except for the height of desk and chair and the degree of watching the monitor.

The long-term wind data are reconstructed from the short-term meteorological data to design the 4 MW offshore wind park which will be constructed at Woljeong-ri, Jeju island, Korea. Using two MCP (Measure-Correlate-Predict) models, the relative deviation of wind speed and direction from two neighboring reference weather stations can be regressed at each azimuth sector. The validation of the present method is checked about linear and matrix MCP models for the sets of measured data, and the characteristic wind turbulence is estimated from the ninety-percent percentile of standard deviation in the probability distribution. Using the Gumbel's model, the extreme wind speed of fifty-year return period is predicted by the reconstructed long-term data. The predicted results of this analysis concerning turbulence intensity and extreme wind speed are used for the calculation of fatigue life and extreme load in the design procedure of wind turbine structures at offshore wind farms.

In this article, we review the statistical methods and theory for dose finding in early phase clinical trials, where the primary objective is to identify an acceptable dose for further clinical investigation. The dose finding literature is initially motivated by applications in phase I clinical trials, in which dose finding is often formulated as a percentile estimation problem. We will present some important phase I methods and give an update on new theoretical developments since a recent review by Cheung (2010), with an aim to cover a broader class of dose finding problems and to illustrate how the general dose finding theory may be applied to evaluate and improve a method. Specifically, we will illustrate theoretical techniques with some numerical results in the context of a phase I/II study that uses trinary toxicity/efficacy outcomes as basis of dose finding.

In this study, for a safety assessment of wheelchair occupant in frontal and side impact of wheelchair loaded vehicle, a sled impact test was perfumed. Each test was carried out total 6 times, by using Hybrid III 50th-percentile male dummy in light weight and electric wheelchair. We estimate MC(Motion Criteria), CIC(Combined Injury Criteria), HIC(Head Injury Criteria), HNIC(Head and Neck Injury Criteria) based on measured data. Through this study, we make an assessment of risk analysis of wheelchair occupant and wheelchair. Through this study, safety standard of wheelchair is to be evaluated.
