The behavior of the masonry lining is studied to gain basic information on how to reinforce the masonry tunnels. Apart from the previous works on the masonry structures, the multi-course masonry structure, realistic in field condition, is considered and the constitutive relationship of the masonry is, therefore, established. The design charts of the orthotropic material properties are proposed according to the stiffness ratio and the crack initiation and subsequent propagation model is also considered to model the brittle nature of the masonry. A numerical analysis on the masonry panel is investigated to verify the proposed model and future works of the masonry lining are briefly explained.

This paper provides a theoretical and conceptual framework for understanding adolescent culture and educational achievement in Korea. In the first part of the paper, the authors outline a research paradigm in cultural psychology and adolescent culture. In the second section, the traditional family structure, the role of parents, and how they have been changed by modernization are outlined. In the third section, socialization practices and parent-child relationship are reviewed. In the fourth section, Western theories that have been developed to explain educational achievement and their limitations are examined. In the fifth section, factors that contribute to educational success of Korean students are presented. In the final section, the impact of centralized, standardized, and rigid educational system that is imposed on adolescents is discussed. The highly regulated and centralized bureaucracy restricts educational and career opportunities for adolescents and it is responsible for the high rate of violence, delinquency, and bullying in Korea. The need for encouraging civil society that allows for diversity of ideas and skills and at the same time maintaining strong relational bonds are discussed.

Pattern activities are useful to develop functional thinking of young students, but there has been lack of research on how to teach patterns. This study explored teaching methods of geometric patterns for developing functional thinking of elementary school students, and then analyzed the lessons in which such methods were implemented. For this, three classrooms of fourth grades in elementary schools were selected and three teachers taught geometric patterns on the basis of the same lesson plan. The lessons emphasized noticing the commonality of a given pattern, expanding the noti ce for the commonality, and representing the commonality. The results of this study showed that experience of analyzing the structure of a geometric pattern had a significant impact on how the fourth graders reasoned about the generalized rules of the given pattern and represented them in various methods. This paper closes with several implications to teach geometric patterns in a way to foster functional thinking.

The topic in this thesis stems from the current education situation that represses learners' freedom by excessive instruction and compulsory institution, in spite of the education helping learners free from inner prejudice as one of its chief aims. In this thesis, to discuss with an educational aspect, I call the learners' freedom in the learning process 'freedom-in-process' and the learners' freedom as the result of learning 'freedom-as-result'. Through this discussion, the conclusions are as follows; First, learners who enjoy freedom-in-process get to obtain freedom-as-result in mathematics education. Second, freedom-in-process and freedom-as-result appear repeatedly in the process of looking for and gaining structures. Freedom-in-process and freedom-as-result are both faces of coin, like seed and fruit which are related mutually and fertilized each other. For this purpose, Mathematics teacher must have awareness of the value of freedom, cherish the freedom, and enjoy it with his students.

Infinitesimal did not play an explicit role concerning definite integral in the textbook nowadays. But studies which investigate understanding of students on definite integral show that many students comprehend definite integral with infinitesimal. Formally infinitesimal is not taught at mathematics classroom, but many students identify definite integral as infinite sum of infinitesimals. This means that definite integral itself contains some structural elements that allow infinitesimal interpretation. In this study we investigate the role of infinitesimal In the historical development of partition-sum in definite integral, extract didactical issues concerning understanding of definite integral, and analyse Korean mathematics textbooks. Finally we propose some suggestions on the teaching of definite integral which contains the process of refinement intuition.

The purpose of present study is to discover the meaning of the Eogul(억울) which is known as a emotion from perceived unfairness. Even though Eogul has been mentioned as a cause of the Hwabyung in Korean culture there were few studies about it. Researchers designed two studies to provide clear understanding for this concept. In study 1, researchers conducted an open-ended questionnaire for 44 participants to deduce the cultural contexts and the whole experience on Eogul. Data were analyzed with grounded theory, the results were cross-checked by different evaluators. According to the analysis, Eogul is not only the negative feelings from the perceived unfairness, but also the motivations and behaviors to resolve the feelings. Especially, what makes Eogul culture-bounded could be related display rules on expressing emotions. We conducted study 2 to clarify the cultural attributes of Eogul in Korean culture. Variables that explain cultural differences were chosen and 123 participants were surveyed with them including the items developed for measuring Eogul. Cultural meanings and implications of Eogul were discussed with the results.

The purpose of the study is to draw competencies of faculty members at graduate school faculty to implements the NCS-based curriculum. A set of competency was deductively derived from a total of three professors and consultants with more than ten-year experiences and has been involved in developing the college curriculum. The political endeavors of the Korean government toward the competency-based education have been implemented as a movement to the NCS-based curriculum. The requirements for the reorganization of curriculum and education system as well as cooperation among faculty, industry, region and development part of NCS were suggested for the activation of NCS based education and the operation of NCS. However, one of the most critical factors in introducing and implementing the NCS-based curriculum is the role of faculty members. Therefore, it is an urgent issue to equip the faculties with required competencies. Result showed that the competencies required professors at graduate school for the NCS-based curriculum implementation were classified into four areas: marco-level curriculum development; micro-level course design; knowledge across areas; and attitude across areas.

The theoretical discussion of generation process and development directions of economic fluctuations are actively discussed. This study describes the economic changes applied to empirical research on economic volatility in Korea under the economic theory of network theory [Acemoglu, et al. 2012, 2010]. For the three years in 2000, 2005, and 2010, the network analysis were applied to industry input-output tables. The research results show that the network economic structures in Korea is shifted from a high connectivity among sectors to a lower connectivity. Also, the impact of key industries and the mutual connectivity of input and out among industrial sectors are weaken. Implications for industry and technology policy are derived form the study results.
