유아교육 현장에서 교사들이 가정과 연계하여 유아와 효율적이고 실천적인 유아환경 보전 교육활동을 할 수 있도록 우리의 환경문화를 중심으로 한 구체적이며 적절한 환경보전 교육활동자료의 개발이 필요하다. 본 논문에서는 유아의 환경교육을 보다 효과적으로 지도하고 유아의 발달단계 특성을 고려하여 환경교육과 내용을 정하고 그 발달단계에 맞는 교육내용을 3D 애니메이션으로 설계하였다.

This paper examines the cross-sectional development of children's conception of place. Previous research by Piaget and Weil, Jahoda, Daggs has questioned how young children develop the ablity to comprehend place. Oral interview and graphic test were made vy the children at the age of 5-14, in order to attain information on their knowledge, understanding and feeling about place. These data were used ti indentify developmental stages through cluster analysis. The results suggest that young children's conception of place develops with an identifiable 4 stages. There is no significant difference in development of conception of place between the 2nd year of kindergarten and the 1st year of elementary school, or the between the 5th, 6th year of elementary school and 1st, 2nd year of middle school. Rather, the 4th year of elementary school is an important and crucial truning point in the development of children's conception of place. It is concluded that children's conception of place develops in line with Piaget's general cognitive developmental theory in which the pre-conceptual stage ends at age 7 and the concrete-operation stage starts at age 11 to 12.

This study analysed 8 gifted students' behavior of using calculator in the 5th grade based on qualitative data of direct proportion class with the utilization of the calculator. Pretesting with questionnaire had been made to verify students' developmental stages of proportional reasoning, and the stage was categorized according to Baxter & Junker (2001). The learning contents were made of worksheet, and the researcher held the class for 60 minutes. For analysing data, record of class was gathered to make a transcript and analysed it with Guin & Trouche' behavior of using calculator type. According to the result, each type of the behavior affected students' development of proportional reasoning differently.

This study is to find a theoretical basis for the effective teaching-learning of the geographical concept through comparing two cognitive pshychological perspectives: Piaget's cognitive development stage theory and Vygotsky's theory with higher mectal function and zone of proximal development(ZPD). Piaget't theory of cognitive development stage has been empirically proved in the spatial concept development and provided a basis for geographical educational psychology. In spite of this contribution, it has its own limitation in that students cannot learn cocepts beyond their cognitive development stage. On the other hand, Vygotsky supposed that concept development has been done by teaching-learning. This study suggests that Vygotsky's theory gives more comprehensive thoretical basis for its effective teaching-learning about the geographical concept development.

Mentoring as a human resources development program is being reconceptualized because of the rapidly shifting work environment which has been recently focused on the necessity of knowledge management. That is, new mentoring network theory as a reconceptualization of mentoring is structured by researchers who have related social network theory and mentoring and they have discovered that the development of individual and organizational is built by the relationships of multiple selves. In their paper, they have asserted that an individual's developmental stage is an important antecedent to the nature of mentoring and developmental networks that are possible. Further, they are suggesting that mentoring developmental network is a key tool for learning, development, and successful performance outcomes in challenging assignments. This paper aims to describe the next empirical research plan that will investigate the developmental stage of teachers as an antecedent of mentoring network. An introduction and background to the research will be explained to provide a conceptual framework for the next study.

The support policy of Micro manufacturers clusters should reflect the regional characteristics of Micro manufacturers clusters, but only similar policies are proposed based on the normal collection of information from related companies. Since the regional characteristics of Micro manufacturers clusters are not understood, they are not reflected in the support policy. Therefore, this study analyzed the characteristics of Micro manufacturers clusters as the formation factors of localization, networking/embeddedness, and innovation synergy/collective learning which are the characteristics of clusters, and applied the development stage based on the analyzed formation factors. Since regional characteristics may be different in the same industry, Micro manufacturers clusters in Changsin and Jangwi, which are representative clusters of apparel sewing industry in Seoul, were compared and studied in terms of regional characteristics and developmental stages. As a result of analyzing the characteristics of Apparel Sewing Micro manufacturers clusters, clusters of peers were found to be higher in Changsin than in Jangwi in localization. However, in the synergy and group learning, the Changsin area was mainly centered on designers and the Jangwi area was centered on Micro manufacturers, the Changsin area was active while the Jangwi area was passive in participating in fairs and seminars, and in sample and production. As a result of examining the two formation factors, the development stage of Micro manufacturers clusters in the two regions is progressing beyond the industrial district in the case of Micro manufacturers clusters in Changsin apparel sewing, and the Micro manufacturers clusters in the Jangwi apparel sewing are analyzed to stay in the industrial district. Innovative and long-established garment sewing clusters suggest that the government's support policy needs to reflect the characteristics and development stages of the two regions for sustainable growth.

A method to design a critical height of embankments is presented so as to mobilize fully soil arching in pile-supported embankments. The behavior of the load transfer of embankment weights on pile cap beams was investigated by a series of model tests performed on pile-supported embankments with relatively wide space between cap beams. The model tests explained that the behavior of the load transfer depended very much on the height of embankments, because soil arching could be mobilized in pile-supported embankments only under enough high embankments. The measured vertical loads on cap beams coincided with the predicted ones estimated by the theoretical equations, which have been presented in the previous studies on the basis of load transfer mechanisms according to either the punching shear failure mode during low filling stage or the soil arching failure mode during high filling stage. The mechanism of the load transfer was shifted beyond a critical height of embankment from the punching shear mechanism to the soil arching mechanism. Therefore, in order to mobilize soil arching in pile-supported embankments, the embankments should be designed at least higher than the critical height. A theoretical equation to estimate the critical height could be derived by equalizing the vertical loads estimated by the load transfer mechanisms on the basis of both the punching shear and the soil arching. The derived theoretical equation could predict very well the experimental critical height of embankment.
