This study aimed to investigate couple relationship and related variables of women immigrants. Especially, the study focused on curve term between couple relationship and related variables. The data were collected from a sample of 346 women immigrants living in S city, Chungnam province. First, the study indicated that there was some curve relationship between couple satisfaction and period of residence in Korea. Namely, the couple satisfaction of women immigrants was likely to decrease at the early period of residence, but the longer the period of residence was, the higher the couple satisfaction was. Second, the result revealed that there was no significant relationship between couple satisfaction and level of Korean proficiency. Third, there was some curve relationship between couple satisfaction and satisfaction of life. The couple satisfaction was likely to increase in a shape of curve according to the increase of life satisfaction.

This paper presents a systematic approach for estimating material performance of concrete mixture design based on satisfaction curves developed from statistical evaluation of existing or newly obtained material property related data. In performance based material design (PBMD) method, concrete material used for construction of a structure is designed considering a structure's specified performance requirements based on its usage and characteristics such as environmental conditions, structure types, expected design life, etc.Satisfaction curves express the probabilities that one component of substrates (i.e., aggregate size, cement content, etc) of concrete mixture will sustain different criterion value for a given concrete mixture design. This study presents a statistical analysis method for setting up concrete material parameter versus concrete criterion relationships in the form of satisfaction curves and for estimating confidence bounds on these satisfaction curves. This paper also presents an analysis method to combine multiple satisfaction curves to form one unique satisfaction curve that can relate the performance of concrete to a single evaluating value. Based on several evaluated mixture design examples for various material properties, the validity of the proposed method is discussed in detail.

This study was done to investigate the effects of family relationship on satisfaction with life in women immigrants. The participants were 346 women immigrants in S city, Chungnam province. The data were collected through self-reported questionnaires which were constructed to include such scales as satisfaction with life and family relationship. First, satisfaction with family relationship ranked in order of couple, parents-in-law, and brothers-in-law and sisters-in-law. Second, as the women immigrants were younger, and their wedding time was shorter, satisfaction with couple was higher. Third, when women immigrants were between 20 and 30 years old in age, and between 2006 and 2010 in wedding year, satisfaction with parents-in-law were higher. Fourth, when women immigrants were between 20 and 30 years old in age, and 2006 and 2010 in wedding year, satisfaction with brothers-in-law and sisters-in-law were higher. Fifth, satisfaction with life was higher for women immigrants with younger age, lower educational level, and shorter residence and wedding time. Sixth, curve term more accounted for relationship between satisfaction with parents-in-law and life. Seventh, significant predictors influencing satisfaction with life were satisfaction with couple, and brothers-in-law and sisters-in-law.

The purpose of this study is to identify the objective picture of developmental pattern of marital satisfaction of couples based on family life cycle length of marriage marriage cohort birth cohort and age of couples using data from 317 couples in urban cities. The result indicate that the U-curve of marital satisfaction is the special pattern of family life cycle while W-curve is more dominant pattern when data are analysed with length of marriage birth cohort and marriage cohort. The couples differ in their assessment of marital satisfaction through entire their life span which seems for wives to become more dissatisfied over time. The similarity of developmental pattern the spouses appears only in their birth cohort. Discussion and recommendations for future research of the marital satisfaction are suggested.

Curve tessellation, which generates a sequence of points from a curve, is very important for curve rendering on a computer screen and for NC machining. For the most case the sequence of discrete points is used rather than a continuous curve. This paper deals with a method of tessellation by calculating the maximal deviation of a curve. The maximal deviation condition is introduced to find the point with the maximal deviation. Our approach has two merits. One is that it guarantees satisfaction of a given tolerance, and the other is that it can be applied in not only a polynomial curve but its offset. Especially the point sequence generated from an original curve can cause over-cutting in NC machining. This problem can be solved by using the point sequence generated from the offset curve. The proposed method can be applied for high-accuracy curve tessellation and NC tool-path generation.

PURPOSES : The purpose of this research is to analyze the characteristics of panels that affect the evaluating results of riding quality and to evaluate the appropriateness of roughness management criteria based on ride comfort satisfaction. METHODS : In order to analyze the influence of panel characteristics of riding quality, 33 panels, consisting of civilians and experts, were selected. Also, considering the roughness distribution of the expressway, 35 sections with MRI ranging from 1.17 m/km to 4.65 m/km were selected. Each panel boarded a passenger car and evaluated the riding quality with grades from 0 to 10, and assessed whether it was satisfied or not. After removing outlier results using a box plot technique, 964 results were analyzed. An ANOVA was conducted to evaluate the effects of panel expertise, age, driving experience, vehicle ownership, and gender on the evaluation results. In addition, by using the receiver operating characteristics (ROC) curve, the MRI value, which can most accurately evaluate the satisfaction with riding quality, was derived. Then, the compatibility of MRI was evaluated using AUC as a criterion to assess whether the riding quality was satisfactory. RESULTS : Only the age of the panel participants were found to have an effect on the riding quality satisfaction. It was found that satisfaction with riding quality and MRI are strongly correlated. The satisfaction rate of roughness management criteria on new (MRI 1.6 m/km) and maintenance (MRI 3.0 m/km) expressways were 95% and 53%, respectively. As a result of evaluating the roughness management criteria by using the ROC curve, it was found that the accuracy of satisfaction was the highest at MRI 3.1-3.2 m/km. In addition, the AUC of the MRI was about 0.8, indicating that the MRI was an appropriate index for evaluating the riding quality satisfaction. CONCLUSIONS : Based on the results, the distribution of the panels' age should be considered when panel rating is conducted. From the results of the ROC curve, MRI of 3.0 m/km, which is a criterion of roughness management on maintenance expressways, is considered as appropriate.

The purposes of this study were to verify the longitudinal mediating effects of work-family balance on the relationship of role recognition in the family, marital intimacy and job satisfaction of married women, and to introduce longitudinal mediating effects by using latent growth curve modeling and autoregressive cross-lagged modeling. The subjects were married women from the third year data of the Korean Longitudinal Survey of Women and Family. Structural equational models were conducted with Amos ver. 21.0. The major findings are as follows. First, the result of the longitudinal mediating effects of latent growth modeling is the rate of change of work-family balance mediated between the rate of change of role recognition in the family and the rate of change of job satisfaction, and the rate of change of work-family balance mediated between the rate of change of marital intimacy and the rate of change of job satisfaction. Second, when using the autoregressive cross-lagged modeling, the more role recognition and marital intimacy of third year were the more work-family balance of fourth year, job satisfaction of fifth year. In both models, work-family balance mediated between role recognition in the family, marital intimacy and job satisfaction. Therefore, through this study, mediating effects of work-family balance can be found that there was a longitudinal effects.
