Overexcitability (OE) and social self-concept are the integral affective characteristics of science-gifted students. Overexcitability refers to sensitivity as an internal disposition to give a more often, longer and more intensive reaction to a wide variety of stimuli, and social self-concept refers to the way of behaving in society, especially at school in the case of students. The purpose of this study was to examine the overexcitability and social self-concept of science-gifted and non-gifted elementary school students. The subjects in this study were 135 gifted elementary students belonged to gifted education centers or gifted classes and 91 ordinary elementary students. An overexcitability test and a social self-concept test were conducted to the subjects, and the collected data were analyzed by SPSS. The findings of the study were as follows: First, the score of the science-gifted was significantly higher than that of the ordinary students in all sub-domain of OE (psychomotor OE, sensual OE, emotional OE, intellectual OE, emotional OE) and social self-concept. Second, the science-gifted students who attended gifted education centers and community gifted classes scored significantly higher than the ordinary students in overexcitability. Based on conclusions, implications for teaching the science-gifted were discussed.

Objective: The purpose of this study is to analyze the science concepts and teaching and learning methods presented in the science education-related activities of the Nuri Curriculum teacher guidebooks for ages 3-5. Methods: The research data included 772 activities related to science education in the teachers' guidebook. The analysis of science concepts was based on physical science (force and motion, physical structure, electricity and magnetism, light and shadow, sound properties), chemistry (material properties, material reaction), life science (organizational structure, growth and change, heredity and evolution, animal plant and human relationships), earth science (earth system interaction, earth system structure, and universe), engineering (designed world, engineering design, engineering, technology and society) and ecology (environment preservation). Teaching and learning methods were analyzed according to the types of small and large group activities and of free play activities. Results: Science concepts were mainly presented in the fields of engineering, chemistry, and life science commonly among children aged 3-5, whereas the concepts of physical science were lowly presented in all ages. Science concepts appeared mainly in the daily subjects of 'animal plant and nature', 'life tools', 'environment and life', and 'spring, summer, autumn and winter'. As the teaching and learning method, free paly activities (science area, free outdoor selection activity, math and manipulative activity) were mostly used for the ages of 3 and 4, and small and large group activities (cooking, story sharing, music activity) were for the age of 5. Conclusion/Implications: It is necessary to select the level of science area and concept that can be taught according to the age of children and the timing of the teaching.

The Industrial Revolution brought great development to the whole human history by the improvement of productive capacity. However, high speed development absorbed just on growth gave rise to resource depletion attack and economical inequality. If it might be neglected human society will meet unsustainable development situation. So UN has made effort to make sustainable development(SD) through global band together. SD concept considers it important to promote current development not giving damage to next generation's development. Then economy, environment and social integration should be harmonized and it demands governance for its actualization. SD gets to be a matter of common interest in education. New Millenium development Goals make African poor countries that are in blind spots of development advance toward gradual sustainable development by supporting programmes to these countries. Thus sustainable development education(SDE) is for future. It has an aim to give suitable education for all people who are all over the world. SDE tries to make health society and successful economical life for all. The concept of SD is found in the essential aims of Christian school and Christian education seeking justice and shalom. Christians are called as transformers for servant mission giving recover in corrupt world. Firstly, Christian school practise this mission making students think on Christian perspectives. Then it makes students serve for environment, economical fairness, social integration with servant mission. Also Christian school has a mission to seek both justice and shalom as a praxis beyond the intellectual dimension of education until fulfilling justice and shalom for all who are all over the world. Thus it can be that Christian school is an important educational institution for realizing sustainable development in that it is always to seek justice and shalom through restoration on the Christian educational perspective.

This study was performed to clarify 'jajonshim' which is different from self-esteem in its social representation and concept in Korean society. In order to refine the notion of 'jajonshim', we first referred to literature and short essay on jajonshim and analyzed its cultural meaning and social representation in Korea. As a result, jajonshim was considered necessary condition for human beings in Korean culture. Although jajonshim was not well recognized normally, it became critical when it was threatened by others and considered to be what one must save as well. Furthermore, the ground theory designed by Strauss and Corbin was utilized in order to analyze Korean interviewees' experience of jajonshim. Koreans believed that their jajonshim was injured when others disrespected their values, which consequently produced negative emotions. When their jajonshim was damaged, people also used 3 coping strategies to recover it. Based on the results, jajonshim was distinguished from self-esteem. First, jajonshim is a type of self-awareness people experience when they are disrespected; thus, it is different from self-esteem which is maintained stable regardless of any events or situations. Second, unlike self-esteem which is solely evaluated by oneself, jajonshim is evaluated by other people's point of view. This study shows that jajonshim exists in the context of Korean culture and has significance in clarifying the cognitive structure and experience process of jajonshim.

This paper concentrates on the finite element analysis of concrete structures considering the material nonlinearity and time-dependent structural behavior. Using the rotating crack model among the smeared cracking model, the structural behavior up to ultimate load is simulated, and concrete is assumed to be an orthotropic material. Especially to include the tension stiffening effect in bending behavior, a criterion based on the fracture mechanics concept is introduced and the numerical error according to the finite element mesh size can be minimized through the application of the proposed criterion. Besides, the governing equation for steel is systematized by embeded model to cope with the difficulty in modeling of complex geometry. Finally, to trace the structural behavior with time under cracked and/or uncracked section, an algorithm for the purpose of time-dependent analysis is formulated in plane stress-strain condition by the age-adjusted effective modulus method.

In this study, a new methodology fur the assessment of liquefaction potential is proposed and characteristics of the proposed methodology are verified. The experimental parameter of this methodology, that is, the plastic shear strain trajectory, is compared with the dissipated energy. It is shown that this parameter can express the liquefaction behavior which is generated by excess pore water pressure. This methodology takes advantage of the shear strain time history determined from the site response analysis based on the real time history of earthquake. In this site response analysis, shock type and vibration type records of similar predominant frequency are inputted. The liquefaction safely factors based on the proposed methodology and Korean detailed assessment related to the classical method are calculated from the results of the site response analysis and laboratory dynamic tests. Through this study, it is found that the proposed methodology can not only simulate the liquefaction behavior of saturated soils hut also express the seismic characteristics reasonably : leading type, predominant frequency, maximum acceleration, duration time.
