In this study we analyze critically the educational studies on the history of mathematics, and the results of the questionnaires to the mathematics teachers and mathematics teacher educators and interviews with them in order to highlight the problems which ought to be settled for more efficient using the history of mathematics in the mathematics classes. We ought to deepen the understanding of the meaning of mathematical concepts and its essential viewpoints through the historical development of mathematics, going beyond the interest and motivation of learning mathematics. In this respect there are insufficient sides in the results of the educational studies in the history of mathematics and in the recognition of the mathematics teachers about using history of mathematics. And the teachings of the history of mathematics in the mathematics teachers education courses are not sufficient in that they just survey the history of mathematics, and it is the very important task to develop the historic-genetic materials in the school mathematics and study the historic-genetic approach to the mathematics texts.

오늘날은 정보의 홍수라고 표현이 될 만큼 많은 양의 정보를 어디서나 얻을 수 있다. 이러한 많은 양의 정보 중 사람들은 그들이 필요한 정보를 얻기 위하여 인터넷을 사용하며 대부분의 사용자들이 포털 사이트의 검색 서비스를 통하여 그들이 원하는 정보를 검색하고 얻고 있다. 그러나 전통적인 여과 과정을 통해 검증된 인쇄 자원과는 다르게 인터넷상에 있는 자원은 대부분 여과되어 있다고 볼 수 없다. 인터넷상에서 발견되는 정보가 주로 여과되지 않은 상태라는 점을 이해하는 것도 정보를 얻는 사용자 입장에서 매우 중요하다. 그런 의미에서 웹에서는 제공되는 정보에 대한 선정, 조직화, 검색에 대한 표준화가 아직 없기 때문에, 단순히 웹 검색 엔진을 이용한 검색의 결과만을 통해서 원하는 정보를 찾는 것은 쉽 지가 않다(Spink et al, 1999). 비록 원하던 정보를 얻었다 해도 획득한 정보가 신뢰할 만한 것인지를 판단하기가 어렵다. 본 연구에서는 그러한 요구에 부응하기 위해 검색 서비스에 대한 사용자 선호 요인을 선별하고 설문 조사를 통해 검증하고자 한다. 본 연구는 크게 문헌 연구와 실증 연구로 구별되며, 실증 분석에서는 검색 서비스를 사용해 본 경험이 있는 인터넷 사용자를 대상으로 설문을 인터넷 사이트와 설문지를 배부하는 형식으로 진행하여, 통계 패키지를 이용 결과를 분석하였다. 문헌 연구에 따르면 인터넷 사이트를 사용하는데 있어서, 사용자 선호에 영향을 미치는 요인으로 정보 품질, 서비스 연계성, 인지된 유용성, 흥미성, 시스템 품질, UI의 편의성이 있으며 본 연구에서도 이러한 요인을 중심으로 연구 모형을 정하였다. 이러한 요인들에 대하여 가설을 정해 실증 분석을 한 결과, 기본적으로 검색 서비스에 대한 인지된 유용성과 UI의 편의성은 사용자 선호에 영향을 미치는 것으로 나타났다. 반면에 정보 품질, 서비스 연계성, 흥미 성, 시스템 품질은 사용자 선호에 영향을 미치지 못하는 것으로 나타났다. 그러나 정보 품질과 시스템 품질의 결과는 유의 수준에서 크게 넘어가지 않는 결과가 나와 반드시 영향을 미치지 못하는 것은 아니라고 조사되었다. 본 연구는 검색 서비스라는 특정 서비스에 대해서 사용자 선호에 영향을 미치는 요인에 대해서 알아보고자 하였다. 이는 학문적인 측면에서 기존의 통합적인 웹사이트 평가에 대한 연구의 확장을 가능케 하였고, 개인사용자 측면에서는 좀더 좋은 정보를 제공하는 검색 서비스에 대한 이해를 높일 수 있는 계기가 되었다고 할 수 있다.

In creating an illustration, rather than depend on the subjective expression of the illustrator, one should consider the characteristics of child cognitive development. Illustrations should be those which can arouse child's interesting and which can be educational. To do this, first, characteristic expressions shown in children's pictures can be used to arouse child's interesting. In creating an illustration, one should consider sufficiently "intuitive form" and "representative form" in order to appeal to curiosity of child. Second, illustrations should be able to be helpful to the development of child's intellect, emotion and imagination. The form is desired to be adequately exaggerated or reduced feature, to have anthropomorphic figure and to be fantastic composition considering the egocentrism and animalism of the child. As mentioned above, it can be said characteristic expression in picture book illustrations are affected by the two points - fascinating expression drawn by child and expression by illustrator, which can be helpful to the development of intellect, emotion and imagination.otion and imagination.

Previous research in leisure motivation has been limited in terms of its overwhelming interest in beneficial outcomes of leisure activities, its short of coverage on wide range of modern leisure activities, and its lack of cultural perspectives. In order to overcome those limitations, the present research conducted a survey in which motives to participate in 48 leisure activities and frequency and importance of the activities were assessed. We categorized 7 categories of leisure activities (skill-involved, social, personal hobby, goal-oriented, relaxing, digital, and voluntary) and 7 categories of leisure motives (achievement, intimacy, psychological comfort, sensation-seeking, secondary, self-promoting, and no-fun). On the basis of the categorizations, momentary leisure motives and individual differences of the leisure motives were conceptualized and tested as a preceding factor of selection of leisure activities. This conceptualization was discussed in its practical implication of leisure education, consulting, and policy.
