This study analyzed the process of steps in a program introducing Renzulli's enrichment triad model and various levels of posing open-ended problems of those who participated in the program for mathematics-gifted elementary students. As results, participants showed their abilities of problem posing related to real life in a program introducing Renzulli's enrichment triad model. From eighteen mathematical responses, gifted students were generally outstanding in terms of producing problems that demonstrated high quality completion, communication, and solvability. Amongst these responses from fifteen open-ended problems, all of which showed that the level of students' ability to devise questions was varied in terms of the problems' openness (varied possible outcomes), complexity, and relevance. Meanwhile, some of them didn't show their ability of composing problem with concepts, principle and rules in complex level. In addition, there are high or very high correlations among factors of mathematical problems themselves as well as open-ended problems themselves, and between mathematical problems and open-ended problems. In particular, factors of mathematical problems such as completion, communication, and solvability showed very high correlation with relevance of the problems' openness perspectives.

This study has verified Family Functioning, Communication and Spiritual Wellbeing, to increase the family functioning in Adult Women. 236 adult women were chosen as the samples for the study, they are now currently registered in the church adult women in Seoul. The instruments used for this study were the Family functioning scale by Olson, the communication scale by David H. Olson and Howard L. Barnes and spiritual wellbing Scale by Palautzian and Ellison Folkman. Data collection were form March to April, 2003. To get the descriptive statistics, SPSS Program, Pearson Correlation Coefficients and stepwise multiple regression were used for analyzing data. The results were as following: 1. Represents the degree of family functioning, communication and spiritual wellbeing, on subjects. Means scores of this study are following: spiritual wellbeing 67.92, lower level of cohesive(5.19) and adaptive(3.93), communication 58.14, lower level of open(5.15) and closed(4.71) and family functioning 95.58, lower level of religious(7.70) and existential(7.63). All each lower level of family functioning, communication and spiritual wellbeing, on subjects were derived significantly different(p.05). There were significant correlation among the variables of subjects. The cohesive family functioning score was significant related to the adapted(r=.588). Especially, the closed communication score showed inverse correlations open family functioning(r=-.424) and open communication score(r=-.680). The existential spiritual wellbeing score also was significant related to the cohesive(p<.001) and adaptive(p<.05) family functioning, open communication(p<.05). Especially, the closed communication score showed inverse correlations existential spiritual wellbeing (r=-.202). The existential spiritual wellbeing score also was significant related to the religious(r=.815, p<.001). These results will not only emphasis the need of family functioning to elevate and decrease the Closed family communication but suggest the important points of gathering various data and analysis about economic, education and marital status. Finally, related to mental health nursing, a community can get the utmost out of these results to keep offering education and practice of family mental health for adult women.

Due to rapid development of mobile communication terminals and various requests of their users, multimedia information including image information has been the basis of mobile communication contents. In order to use vectored image information efficiently, which is more favorable than bit-mapped image information when transmission delay time and costs are considered, efficient vector graphics supporting systems are needed. Therefore, vector graphics kernel systems have been proposed and standardization attempts have been made in order to increase interoperability. In this paper, a vector graphics kernel based on OpenVG is designed and implemented. OpenVG was proposed as a standard vector graphics kernel by Khronos Group recently. The implemented vector graphics kernel, named by alexVG, is developed on a PC emulator as well as on a development board equipped with an ARM processor. In addition, performance tests are made in order to verify its functions.

The purpose of this study was to investigate the effects of children's temperament, parent-child communication, peer relationships on children's cognitive and affective happiness. The participants consisted of 396 elementary school students aged 10-13 dwelling in Jeonbuk province. Data was analyzed through descriptive statistics, t-test, regression analysis using the SPSS 18.0 program. The most salient results from this study were as follows: first, there were statistically significant differences in the children's happiness according to academic performance and family's economic level; children who considered themselves to have good grades and to have a higher standard of living were happier than other groups. However, there was no significant difference in children's happiness in relation to gender. Second, children's temperament(sociability, activity), parent-child open communication and peer relationships were positively associated with the children's cognitive and affective happiness. Children's emotional temperament, parent-child problem communication were negatively associated with the children's cognitive and affective happiness. Third, as the results of regression analysis, parent-child open communication, children's temperament(activity, sociability), peer relationships were considered to be the most influential factors in explaining cognitive happiness. And parent-child open communication, parent-child problem communication, children's temperament(activity) were influential factors in explaining affective happiness. In conclusion, children's happiness is critically affected not only by internal variables but also environmental ones such as parents and peers.

The purpose of the present study to investigate relationships among family background factors (i. e. adolescents' sex, mother's educational level and employment status. family's SES, and family types), mother-adolescent communication patterns and ego-identity development of adolescents. The subjects were 169 mother-adolescent dyads living in Seoul. Statistical methods used for the data analysis were frequencies, percentiles, Mean, ANOVA, Duncan's multiple range test, Pearson's product-moment correlation, regression analysis, ANCOVA, and Cronbach's ${\alpha}$. The results were as follows: (1) Significant differences of the adolescents were between family's SES and open communication patterns, between family types and problematic communication patterns. (2) Significant differences of the mothers were between family's SES and open communication patterns, and among family's SES, mother's educational level and problematic communication patterns. (3) There were significant differences in ego-identity of adolescents according to family's SES. (4) There were significant relationships between mother-adolescent communication patterns and the ego-identity development of adolescents. (5) The most influential variable explaining adolescents' ego-identity development was found to be problematic communication patterns perceived by adolescents. Family background factors and mother's communication patterns were not found to have significant effects.
