The purpose of this study was to determine the possibility of character education in the middle school home economics program: by extracting learning factors that can cultivate gratitude disposition from the eighth grade in the unit of 'clothing life' of middle school HE text, developing five teaching-learning lesson plans and learning materials, and applying them in classrooms to see any changes in gratitude disposition standards before and after its application. Five teaching-learning lesson plans for the cultivation of gratitude disposition were developed, and completed after three experts in home economics verified their validity and revised them. From June 1, 2010 to June 30, 2010, five classes were to 210 grade students at a Gyeongbuk Junior School, and dispositions were investigated before and after the classes. Gratitude disposition standards used GQ-6, like McCullough, and for before-and-after-inspection comparison, t-test and analysis of open-ended questionnaires were carried out. The results proved the instruction effective. Before the class for the cultivation of gratitude disposition, students had a gratitude disposition average of 2.87(out of 5). After the class, the average was 3.35, which shows that students had improved considerably. Also, in analysis of a open-ended questionnaire, it was said that the class had been provided the opportunity to think about the value of nature and neighbors and that the class content reminded them about appreciation. In conclusion, for the character education in other areas of middle school home economics, teaching-learning lesson plans development must be attained to further this character education program.

The purpose of this research was to investigate ways of restructuring key competencies (KCs) in preparation for a revision of Korean science curriculum. Recently a number of countries have reformed their curricular using competencies as a key element because they believe that competencies-based curriculum helps students build up the necessary skills to live in the future society. Through literature reviews, in-depth interviews with experts and teachers, expert meetings, Delphi methods, and surveys with teachers, three major categories of KCs emerged as follows: Character competencies, Intellectual competencies, and Social competencies. For each major category, its definition, characteristics and teachers' comments are discussed. The specific components of KCs for each major category and implementing KCs should be determined at the subject- and teacher-level based on teacher professionalism. In the conclusion section, we suggested a couple of important points that deserve readers' attention when we reconstruct science curriculum by incorporating three major categories of KCs. When we develop a science curriculum in the future, we need to include three major categories of KCs, and set up KCs as a minimum set of goals for all students. We need to remember that specific components of KCs for each major category and linkage among KCs may vary depending on science topics and objectives.

Purpose of the Study : This research aims to examine the core values of ESG (Environmental, Social, and Governance) from a Christian perspective and explore the direction of Christian education that fosters character traits such as service, compassion, responsibility, and sharing through the process of design thinking. Content and Method of the Study : By investigating the background and definition of ESG, ESG practices in businesses, and the current status and values of ESG education in universities, this study examined the core values of ESG from a Christian perspective. Subsequently, the study explored and proposed directions for applying ESG education methods infused with character traits such as service, compassion, responsibility, and sharing through the process of design thinking. Conclusion and Recommendations : Through this study, the core values of ESG have been derived as elements from a Christian perspective, and exploration has been made on how to integrate them into the design thinking process. Consequently, this study has identified the potential to integrate ESG into the design thinking process with a focus on elements from the perspective of Christian education. This could serve as foundational material for education seeking to apply ESG through the integration of design thinking, and it is hoped that it will be helpful as a basis for further research. Subsequent studies should aim to construct a more systematic framework for the direction proposed in this study through expert reviews.

Purpose of this paper is to determine the appropriate size of a center notched disk specimen for mode I fracture toughness $K_{IC}$. For this purpose, mode I test results with various sizes of center notched disk were compared with the RILEM three-point-bend test ones. Compressive strength of concrete used in this paper was 44.9 MPa. Diameters of 200, 300, 400 mm, thickness of 75, 100, 125 mm, and notch length ratios an of 0.3, 0.4, 0.5, 0.6 were used for the mode I disk test. Also, diameter of 300mm thickness of 100mm, and notch length ratios a/R of 0.3, 0.4, 0.5, 0.6 were used for the mixed mode disk test. Mixed mode stress intensity factors were investigated by changing notch angles for the disk specimen. Stress intensity factors of a center notched disk were calculated with the various methods for comparison. From the test results, mode I fracture toughness calculated from the disk specimen with diameter of 300 mm, thickness of Inn and notch length ratio a/R of 0.5 was very similar to the RILEM three-point-bend test ones. And it is verified that stress intensity factors for mixed mode can be easily calculated with the disk specimen.

Fracture toughness is a material property for crack initiation and propagation in fracture mechanics. For mode I fracture toughness measurement in concrete, RILEM committees 89-FMT proposed three-point bend tests based on the two-parameter fracture model. But, there is no proposed test method as a standard for mixed mode test for now. And RILEM three-point bend test procedure is complicate. Therefore, in this study, brazilian disks of various size were designed as the concrete with a similar specified concrete strength and maximum size of coarse aggregate($G_{max}$) were respectively 20mm and 40mm. And mode I fracture toughness of brazilian disks was compared with that of RILEM three-point bend test. As a result, it was suggested appropriate size(thickness, diameter) and notch length ratio of brazilan disk on the $G_{max}$. And it was verified that stress intensity factors for mixed mode can be easily calculated with the disk specimen. Stress intensity factors of a concrete brazilian disk were evaluated with finite element analysis and five terms approximation for comparison.
