Creativity has very important significance to children. Although active researches and educations on other studies (for instance, mathematics, science, logics, music, etc) are being done, evaluation or development on children's creativity in design is very inadequate. Therefore, this study is a basic research to develop evaluation to judge design creativity of children as an incipient stage of educational method development to develop children's creativity in design. Evaluation categories (originality - novelty/fun, practicality-function/possibility) that can evaluate design creativity of children were drawn out based on documentary records, and as the results or performing experimental research to figure out correlativity between creativity of idea and design creativity targeting children in second grade of elementary school, subordinate provinces of idea's creativity related to design creativity were fluency and elaboration. However, it does not mean that fluency and delicacy are the only subordinate provinces of idea's creativity related to design creativity, but they are more influential compared to other provinces (creativity, abstractness of title, and resistance to premature closure) This study is to prepare basic framework of educational method to improve design creativity education of children, and has its meaning to complement what are lacked in design creativity through the educational method.

In recent years, bullied students and rogue groups in teenagers make many serious social problems. In this paper we propose a novel approach that more objectively analyzes peer relationships among students. As the data for objective analysis, we use communication history records that are collected from various communication tools such as telephones, e-mails, and messengers. We use the simple intuition that communication history records implicitly contain peer relationship information. And, we adopt data mining techniques for the more systematic analysis. The proposed peer relationship analysis consists of the following steps. First, we formally define the notion of degree of familiarity between friends, and present mathematical equations that compute the degree based on communication history records. In the proposed method, we use the intuition that the degree of familiarity from student x to student y becomes higher as x makes the more communications with y. Second, by using the degree of familiarity between students, we find out the students who are potentially bullied. This procedure is based on the assumption that a bullied student may have a very small number of history records from other students to him. Third, we adopt the clustering technique, one of the most representative data mining techniques, to find out meaningful student groups by using the degree of familiarity. To use the clustering technique, we formally define the notion of similarity between friends based on the degree of familiarity, and perform clustering using the notion. Last, to show the practicality of the proposed method, we have implemented the method and interpreted the meaning of the experimental results. Overall, we believe that our research result provides an effective framework that analyzes peer relationships more objectively and more systematically.
