In recent years the pure displacement formulation for plate elements has not been as popular as other formulations. We revisit the pure displacement formulation for shear-deformable plate elements and propose a family of N-node, displacement-compatible, fully-integrated, pure-displacement, triangular, Mindlin plate elements, MIN-N. The development has been motivated by the relative simplicity of the pure displacement formulation and by the success of the existing 3-node plate element, MIN3. The formulation of MIN3 is generalized to obtain the MIN-N family, which possesses complete, fully compatible kinematic fields, in which the interpolation functions for transverse displacement are one degree higher than those for rotations. General element-level formulas for the thin-limit Kirchhoff constraints are developed. The 6-node, 18 degree-of-freedom element MIN6, with cubic displacement and quadratic rotations, is implemented and tested extensively. Numerical results show that MIN6 exhibits good performance for both static and dynamic analyses in the linear, elastic regime. The results illustrate that the fully-integrated MIN6 element has excellent performance in the thin limit, even for coarse meshes, and that it does not require shear relaxation.

This study examined the multicultural efficacy and job satisfaction of multicultural family visiting instructors. The subjects were 750 visiting instructors from 140 multicultural family support centers in Seoul, 6 metropolitan cities, 9 provinces, and other cities and counties. Data were analyzed through frequency, percentages, Pearson's correlations, One-way ANOVA, Scheff$\acute{e}$ post-hoc test, independent t-test, and stepwise multi-regression using PASW 18.0. The findings are as follows. First, there were statistically significant differences in all subscales of multicultural efficacy according to the teaching experiences of the multicultural family visiting instructors. On the other hand, there was a statistically significant difference only in trust in the relationships with multicultural families according to the teaching experiences of the multicultural family visiting instructors. Meanwhile, the independent t-test showed that there was a significant difference only in satisfaction regarding treatment and salary according to the assigned work. Second, the stepwise multi-regression models revealed that three subscales (job performance, trust in the relationships with the multicultural families, job aptitude) of job satisfaction were influenced by multicultural efficacy according to both the teaching experiences and assigned work, but this was no the case for satisfaction about treatment and salary. Regardles of teaching experience or assigned work, teaching efficacy in multicultural efficacy affected all subscales of job satisfaction except for satisfaction about treatment and salary. The implications for future studies are also discussed.

We examined the effects of family and home literacy environments on the vocabulary and reading abilities of 3 to 5-year-olds. In particular, SES was considered against home literacy environment. The sample consisted of 366 Korean children and their mothers. We found that the level of mother's education was related to the child's vocabulary test score. After controlling for family factors, home literacy environment score positively predicted children's performance both in vocabulary and reading tests. Magnitudes of differences between the two literacy groups (high and low home literacy environment) became larger in the children from relative lower income families. Magnitudes of differences for vocabulary and reading tests was strikingly large in the low-income group both in vocabulary and reading tests. These findings shed lights on the importance of parent education and family services for low-income families with preschool children.

This research was carried out to investigate the determinants of job performance and turnover intention of female advisors in mobile communication contact centers located in Daegu. The independent variables are individual characteristics, work duty related variables, working environments and the leadership of the middle managers. The factor analysis and the hierarchical regression analysis were implemented to the subjects of 282 advisors which gathered from 7/14/2008 to 7/23/2008. The results are as follow. First, the older advisors were, the higher job performance was. The higher educational background presented more turnover intention, and married advisors had higher job performance than unmarried ones. Second, the longer employment period showed higher job performance. Third, As advisors were more satisfied with promotion and welfare policy, and with coworkers, higher job performance was presented. As advisors had lower satisfaction with policy and authority, they showed higher turnover intention. Fourth, the leadership of middle managers positively had a influence on job performance and turnover intention. As the middle managers motivated and encouraged advisors well, the advisors showed higher job performance. If the middle managers showed lower charisma leadership, the advisors was intended to turnover more. Fifth, the most influential factor of advisors' job performance and turnover intention was working environments.

The purpose of this study was to analyze the effects of workers' human resource development and their recognition of human resource on-the-job satisfaction. A sample of 4,727 workers that was selected from Korea Labor Panel Data was analyzed by t-test and multiple regression, and was tested by causal effects among related variables. The major findings were as follows: First, the workers' recognition of their job performance level vs. educational attainment was affected by their annual income, job status, educational attainment, gender, and experiences of human resource development. Second, the workers' job satisfaction was affected by gender, age, educational attainment, health status, job status, annual income, experiences of human resource development, recognition of their job performance level vs. educational attainment, and recognition for their job availability. Third, the factors that had a causal effect on workers' job satisfaction were educational attainment, gender, age, health status, annual income, and experiences of human resource development. Above all, workers' educational attainment had a strong direct effect on job satisfaction, and annual income had a strong indirect effect on it. From these findings, it can be concluded that workers' effort and trial for development and investment of human resource played an important role in increasing job satisfaction.

The aim of this study was to identify the performance and requirements of the visiting nursing care using Omaha system in public health center. The highest performance were 'personal hygiene', 'pain', 'medication regimen', 'nutrition', 'physical activity', 'sanitation', 'sleep and rest patterns', 'oral hygiene', 'mental health' in order. The lowest performance were 'sexuality', 'postpartum', 'income', 'family planning', 'pregnancy', 'spirituality', 'abuse', 'reproductive function', 'neglect' in order. Problems such as 'postpartum', 'pregnancy' and 'family planning' need to strengthen the role of visiting nurses according to the region. this result will be the basis for visitung nursing care.

In this paper, a family of decentralized adaptive controller is proposed to control robot manipulators which are governed by highly nonlinear dynamic equations. The controller is computationally efficient since it does not require mathematical model or parameter values of the manipulators. The stability of the manipulators with the controller is proved by Lyapunov theory. The results of numerical simulations show that the system is stable, and has excellent trajectory tracking performance.

The mean residual function is the expected remaining life of an item at age x. The problem of trend change in the mean residual life is great interest in the reliability and survival analysis. In this paper, we develop a family of test statistics for testing whether or not the mean residual life changes its trend. The asymptotic normality of the test statistics is established. Monte Carlo simulations are conducted to study the performance of our test statistics.

The purpose of this study is first to examine the tendency in what kind of activities and difficulties are carried out as family rituals. Second, the study was to investigate the effects of family rituals on family strengths. To accomplish study purpose, 216 married women/men were asked to fill out the survey questionnaires. For analysis of data, SPSS Win program was used to perform Frequency Analysis, MANOVA, Multiple Regression Analysis. (1)In the dinner rituals, it turned out that a main activity was 'serving homemade food' and a majority of subjects had a difficult time establishing a regular ritual due to 'their busy schedule at work'. In the weekend leisure rituals, a main activity was 'paying a visit to suburbs' and a main difficulty was 'lack of mutually available time for all family members'. In the birthday rituals, a main activity was 'preparing a birthday cake' and a main difficulty was 'because family members forget their birthday'. In the wedding anniversary rituals, women's main activity was 'eating out' and men's main activity was 'give a partner to a flower or gift', and a main difficulty was 'because family members forget their birthday' and 'because it was not a wanted celebration'. Finally, in the traditional rituals, women's main difficulty was 'partner doesn't understand my difficulties' and men's main difficulty was 'trouble human relationships with relatives'. (2)The family rituals were significantly different according to the age. (3)'Closeness of family members', 'task performance and problem solving skills' and 'sharing a value system of family members' were affected by the family rituals.
