The purpose of this study is to investigate elementary students' communication in process of applying mathematical modeling. For this study, 22 fifth graders in an elementary school were observed by applying mathematical modeling process (presentation of problem ${\rightarrow}$ model inducement activity ${\rightarrow}$ model exploration activity ${\rightarrow}$ model application activity). And the level of their communication with their activity sheets and outputs, observation records and interviews were also analyzed. Additionally, by analyzing the activity cases of and , this study researched that what is a positive influence on students' communication skills. Whereas showed significant advance in the level of communication, who communicated actively on speaking area but not on every areas showed insensible changes. To improve communication abilities, cognitive tension and debate situation are needed. This means, mathematical education should continuously provide students with mathematical communication learning, and a class which contains mathematical communication experiences (such as mathematical modeling) will be needed.

The purpose of this study is to examine main variables of dysfunctional communication, which worsen marital conflicts in terms of marital interaction and to clarify the relative effects of such variables. The subjects were 295 married males and females, and collected data were analyzed using SPSS WIN 23.0 program. The main findings are as follows : First, the tendencies of related variables showed that the levels of spouses' perspective taking and routine marital responsiveness were higher for both males and females, while the levels of irrational belief for marital relations and dysfunctional communication were low. Second, an analysis of spouses' perspective taking, routine marital responsiveness, irrational belief in marital relations and correlations of dysfunctional communication showed that spouses' perspective taking and routine marital responsiveness for both males and females have negative correlations with dysfunctional communication. The higher spouses' perspective taking and routine marital responsiveness, the lower the level of irrational belief related to marital relations and the lower the level of dysfunctional communication. This study clarifies that spouses' perspective taking, routine marital responsiveness and irrational faith for marital relations influence marital dysfuctional communication and has an implication, in that the findings can be used as basic data for seeking methods to solve problems of couples who experience conflicts derived from dysfunctional communication.

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.

The scheduling problem of large products like ships, airplanes, space shuttles, assembled constructions, and automobiles is very complex in nature. To reduce inherent computational complexity, we often design scheduling systems that the original problem is decomposed into small sub-problems, which are scheduled independently and integrated into the original one. Moreover, the steep growth of communication technology and logistics makes it possible to produce a lot of multi-nation corporation by which products are produced across more than one plant. Therefore vertical and lateral coordination among decomposed scheduling systems is necessary. In this research, we suggest an agent-based coordinating mechanism for multi-level scheduling systems in supply chain. For design of a general coordination mechanism, at first, we propose a grammar to define individual scheduling agents which are responsible to their own plants, and a meta-level coordination agent which is engaged to supervise individual scheduling agents. Second, we suggest scheduling agent communication protocols for each scheduling agent topology which is classified according to the system architecture, existence of coordinator, and direction of coordination. We also suggest a scheduling agent communication language which consists of three layers : Agent Communication Layer, Scheduling Coordination Layer, Industry-specific Layer. Finally, in order to improve the efficiency of communication among scheduling agents we suggest a rough capacity coordination model which supports to monitor participating agents and analyze the status of them. With this coordination mechanism, we can easily model coordination processes of multiple scheduling systems. In the future, we will apply this mechanism to shipbuilding domain and develop a prototype system which consists of a dock-scheduling agent, four assembly-plant-scheduling agents, and a meta-level coordination agent. A series of experiment using the real-world data will be performed to examine this mechanism.
