With rapid economic growth, the urban environment has created a problem of human physical and mental illness. In order to solve these problems, urban forests have emerged as a way to mitigate the environmental risks through improving the polluted environment of the city and improve the quality of life. As the urban forests have expanded, the school forests movement has also been taking an important place recently. The study focused on the performance of school forests by comparing the perceptions among teachers and students about their functions. The questionnaire was composed of 4 questions concerning human matters, 10 questions for space recognition, 4 questions for thermal environment, 2 questions for health promotion, and 20 total questions for composition of survey items. The reliability of the school forest function, number of tree planting areas and quantities, the harmony of the planting, and the satisfaction of the school forest were analyzed in the questionnaire conducted by the school members. Although it does not recognize school forests, it has a positive response to the green space that is built outdoors. It is considered that outdoor education and environmental education are sufficient in school forests and green spaces. The results showed that the outdoor green space was more satisfactory when compared with the general school. Teachers and students' preferences were similar to 'seasonal changes' and' trees of various colors and shapes'. The reliability analysis between each item shows that the coefficient for cronbach's ${\alpha}$ was .700 to .834. The purpose of this study is to identify the perception of forest function among school forest members and to utilize them as a basic data in the future.

Son Jinchaek got into his directing career since 1976 when he founded the theatre group Minye with Huhgyu and others. His experience in Minye was the turnaround of his life; Huhgyu was a teacher in his artist's life whereas Brecht was a teacher for his ideology to make 'Korean Theatre'. From these two teachers, he learned how and why Korean Theatre should be made. Since then, Korean theatre was his calling for 40 years of his directing career. As he established Michoo in 1986, it served a turning point in his art. His focus was on intrinsic attributes of Korean Theatre with Madang Jungshin. With Madang Jungshin, he tried to get over the former generation's fixation on external materials of Korean traditional theatre and folk culture to make Korean Theatre. Rather, he believed Korean Theatre could be realized when it grafted Korean social reality onto the stage, while the form was subsequent. He advocated Korean Theatre should mirror present social reality and circulate social energy. Also, he did not give up aesthetics. On the contrary, his aesthetic style was conspicuously evident in his productions. In spite of his life long career with noteworthy works, the critical discourses are strikingly scarce especially when compared with other senior and peer directors such as Hugh Gyu, Ahn Minsoo, Oh Taesok, and Lee Yoontaek. During his career he has crossed into various genres from Changeuk, Madangnori, and to theatres, which were too versatile to thread them into a discourse and caused a lack of theoretical greeting. Madangnori has anchored its artistic structure on its polished aesthetics which were acclaimed by the general audience for 30 years. For theatre, he concentrated on one production per year to grasp its own style. Theatre works also had revealed his own style of being opened and of being emptied which was certainly different from Madangnori, but had same aesthetic principle within it. This paper attempts to recompose his stylistic features with 'Madang aesthetics' which were based on open space, open acting style, and graphic ensemble. This paper tries to demonstrate how his 'Madang aesthetics' has refined his productions in scenography, acting style, and in more like metaphoric and metonymic symbolic expression of the graphic ensemble. To do this, two productions were explored: eLee Chunpoongjeun and Yulha Ilgyee Manbo. Madangnori was sorely explored by Son Jinchaek with his artistic colleagues Yoon Munshik, Kim Jongyeup, Kim Sungnyu, music designer Park Buhmhoon, and choreographer Guk Sooho. Though it has been ignored for its popular appeal by the doctrinaire theoretical opinions, it started to pull academic attention recently. His theatres are also getting sharp with his 'Madang aesthetics' as well as minimalistic expression in scenography, acting style, and graphic ensemble. Madang Jungshin is the soul and Madang aesthetics is the body in his artistic works. The Madang Jungshin animates the Madang aesthetics, so they become alive in his theatre.

The purpose of this study was closely to explore the guidance experiences of senior elementary teachers who have had over 30 years of teaching experiences in elementary school based on interpretive(or hermeneutic) inquiry. The entry research question was 'What are the guidance experiences of senior elementary teachers like?' Seven senior elementary teachers working for O elementary School in G city participated in this study voluntarily. Each participant was interviewed twice in a consecutive manner. 14 periods of interview were completed all together and each period took about 40-60 minutes. In conclusion, this study conceptualized the guidance experiences of the senior elementary teachers(participants) as follows: First, the concepts of guidance held by the participants were conceptualized as 1) supporting and caring activity helping students to lead joyful school life, 2) assisting activity helping students to grow on good basic life habits, 3) character building activity helping students to lead integrative growth. Second, the fields and contents of guidance held by the participants were conceptualized as basic life habits, manners, and health & safety. Interestingly, these concepts were evolved in connection with their personal, practical teaching experiences rather than in-service teacher education. Third, the guidance methods frequently used by the participants were co-work with parents, exemplary storytelling, counselling, and praise. The participants applied these methods differently according to the grade, individual difference, and school curriculum policy to some degree. Fourth, the participants have experienced a lot of struggles with students, teachers, and parents in doing their guidance practices throughout the whole teaching career. Their guidance experiences commonly shifted from more teacher-centered or authoritative to more student-centered or relational way as their teaching years accumulated. Interestingly, all the participants more or less lived as lifelong learners to create their own right space as senior teachers in today's competitive and challenging landscape. This study strongly suggests that responsible teacher education can playa great role of enabling senior teachers to cope with guidance issues successfully. Compared with the speedy social change, the teacher education in Korea had been so authoritative, provider-based, subject-based until recently and it have not met the needs and wants of the elementary teachers in field. This trend has significantly hindered them from catching up with the needs of the speedy social change in terms of contemporary guidance issues. This study is limited in that the data is solely collected based on interview. So, an observational research is strongly suggested in order to uncover the situated understanding of the guidance experiences of elementary senior teachers.

The purpose of this study is to research the actual condition of environment and management of outdoor play at child care centers in Seoul, and to present a planning guideline for outdoor play environment. For this purpose, data were collected by a structured questionnaire and subjects were 164 directors of child care centers located in Seoul. The contents of the questionnaire were composed of general facts about the respondent and facility, environmental condition, managerial condition, and director's understanding about outdoor play. The data were then analyzed using the frequency, percentage, mean and crosstab. The major results have shown the following: 1) Most child care centers in Seoul had some space for outdoor play. 62% of them used front yard and 11 % a rooftop. 2) The space usually included fixed play instruments such as slide and complex unit structures, sand play area, and open area. It also had many natural elements as shrubs and earth. 3) 78% of the centers had a schedule for outdoor play. The schedule operates flexibly according to each center's own day schedule. Generally, a time for outdoor play was 21 to 30 minutes. 4) The directors of child care centers thought highly of outdoor play for it contributes to the balanced development of children. They answered that equipments and spaces, program devices, and teacher's understanding are some of the important factors for active outdoor play. 5) Most of them wanted wood-working area (construction activity area), water play area, and cages.

In this article, for the first time, the seismic behavior of elliptic-braced moment resisting frame (ELBRF) is assessed through a laboratory program and numerical analyses of FEM specifically focused on the development of global- and local-type failure mechanisms. The ELBRF as a new lateral braced system, when installed in the middle bay of the frames in the facade of a building, not only causes no problem to the opening space of the facade, but also improves the structural behavior. Quantitative and qualitative investigations were pursued to find out how elliptic braces would affect the failure mechanism of ELBRF structures exposed to seismic action as a nonlinear process. To this aim, an experimental test of a ½ scale single-story single-bay ELBRF specimen under cyclic quasi-static loading was run and the results were compared with those for X-bracing, knee-bracing, K-bracing, and diamond-bracing systems in a story base model. Nonlinear FEM analyses were carried out to evaluate failure mechanism, yield order of components, distribution of plasticity, degradation of structural nonlinear stiffness, distribution of internal forces, and energy dissipation capacity. The test results indicated that the yield of elliptic braces would delay the failure mode of adjacent elliptic columns and thus, help tolerate a significant nonlinear deformation to the point of ultimate failure. Symmetrical behavior, high energy absorption, appropriate stiffness, and high ductility in comparison with the conventional systems are some of the advantages of the proposed system.

The purpose of this study is to investigate the influences of science leading schools on primary and middle school students' positive experiences about science (PES) through in-depth interviews with teachers in charge of science leading schools. Science leading schools at the primary and middle school level such as Creative Convergent Science Labs and Student Participatory Science Classes were investigated and 11 teachers were participated in focus group interviews. Teacher in-depth interviews were conducted to explore the factors that led to the effectiveness of science leading schools in improving the student's PES in light of operational characteristics of science leading schools, characteristic factors of science leading schools on students PES, and improvement plans and requirements of science leading schools, as well as implications for general high schools. Science leading schools including Creative Convergent Science Labs and Student Participatory Science Classes applied for the leading school funding to secure supplies, equipments, and lab improvement for authentic science classes. In addition, reconstructed the curriculum more broadly than before, and emphasized and expanded student participatory classes and process-centered assessment at the teacher learning community level. Through student-participatory classes, the science leading schools stimulate students' interest in science, provide students with PES) through various instructions including projects, engage students in interesting science experiences in Creative Convergent Science Labs, and enhance inquiry skills and PES as well as science content knowledge. Based on the results, ways to spread the characteristics of science leading schools to general schools are suggested including expanding budget support, securing the space of science labs and improving spatial composition, providing diverse teaching and learning materials, diversifying assessment subjects and methods, and the necessity of teachers' continuous professional development, etc.

Periodontal inflammation increases the risk of tooth loss, particularly in cases where there is an associated loss of alveolar bone and periodontal ligament (PDL). Histological and morphometric evaluation of periodontal inflammation is difficult. Especially, the lengths of the periodontal ligament and interdental alveolar bone space have not been quantified. A quantitative imaging procedure applicable to an animal model would be an important clinical study. The purpose of this study was to quantify the loss of alveolar bone and periodontal ligament by evaluation with micro-computed tomography (micro-CT). Another purpose was to investigate differences in infections with systemic E. coli LPS and TNF-${\alpha}$ on E. coli lipopolysaccharide (LPS) in loss of alveolar bone and periodontal ligament model on mice. This study showed that linear measurements of alveolar bone loss were represented with an increasing trend of the periodontal ligament length and interdental alveolar process space. The effects of systemic E. coli LPS and TNF-${\alpha}$ on an E. coli LPS-induced periodontitis mice model were investigated in this research. Loss of periodontal ligament and alveolar bone were evaluated by micro-computed tomography (micro-CT) and calculated by the two- and three dimensional microstructure morphometric parameters. Also, there was a significantly increasing trend of the interdental alveolar process space in E. coli LPS and TNF-${\alpha}$ on E. coli LPS compared to PBS. And E. coli LPS and TNF-${\alpha}$ on E. coli LPS had a slightly increasing trend of the periodontal ligament length. The increasing trend of TNF-${\alpha}$ on the LPS-induced mice model in this experiment supports the previous studies on the contribution of periodontal diseases in the pathogenesis of systemic diseases. Also, our findings offer a unique model for the study of the role of LPS-induced TNF-${\alpha}$ in systemic and chronic local inflammatory processes and inflammatory diseases. In this study, we performed rapidly quantification of the periodontal inflammatory processes and periodontal bone loss using micro-computed tomography (micro-CT) in mice.
