To obtain more accurate approximation of the true images in the deblurring problems, the weighted global generalized cross validation(GCV) function to the inverse problem with multiple right-hand sides is suggested as an efficient way to determine the regularization parameter. We analyze the experimental results for many test problems and was able to obtain the globally useful range of the weight when the preconditioned global conjugate gradient linear least squares(Gl-CGLS) method with the weighted global GCV function is applied.

The method of Lattice Dynamical System is used to establish a global model on an infinite chain of many local markets interacting each other through a diffusion of prices between them. This global model extends the Walrasian evolutionary cobweb model in an independent single local market to the global market evolution. We assume that each local market has linear decreasing demands and quadratic supplies with naive predictors, and investigate the stationary behaviors of global price dynamics and show that their dynamics are conjugate to those of $H{\acute{e}}non$ maps and hence can exhibit complicated behaviors such as period-doubling bifurcations, chaos, and homoclic orbits etc.

The purpose of this study is to develop and apply a make-a-thon program based on engineering problem solving for science high school students and to analyze the changes of participating students. Through the consultation of teachers and experts, a team-based and student-driven engineering problem-solving-oriented make-a-thon program was developed. And, the program operated using KAIST's human and material resources for 51 students. Students composed of 12 teams studied 12 topics through an engineering problem-solving process, and the overall program satisfaction was very high, on average 4.62. Through this program, students' creative leader competency have been positively changed, especially in cognitive characteristics (diffusion thinking, problem solving ability) and social characteristics (pursuit of social values). Attitudes toward engineering also changed positively, especially in terms of difficulty of engineering, interest in engineering, gender role in engineering, and engineering and occupational factors. In conclusion, it was confirmed that this program is very effective for science high school students with high demand for engineering education.

The purpose of this study is to investigate the environmental perceptions of pre-service secondary school teachers about the global environment. The Subjects are 133 pre-service secondary school teachers. As an indicator of environmental perceptions, the modified New Environmental Paradigm (NEP) instrument was used. This modified NEP instrument consists of four dimensions: the negative results of growth and technology, relation of humankind and nature, quality of life, and limits of biosphere. The results of this study suggested that a majority of pre-service secondary teachers held ecological environmental perceptions. They also had a similar environmental perception to education major. However, there were significant differences in environmental perceptions and the variables of education experience on environment-related subjects. Based on the findings of this study, it is recommended that environment-related subjects. Based on the findings of this study, it is recommended that environmental education be a mandatory course in education programs.

The purpose of this research is to investigate the relationship between global citizenship, self leadership and global health competencies in nursing students and utilize the basic data for development of educational program to increase of global health competence. A convenience sample of 207 subjects were invited from three university. Data were analyzed using t-test, ANOVA and Pearson's Correlation with SPSS PC 18.0 program. Global health competencies showed that there were differences according to religion, taking education related to global health competency, exposure to mass media about global health. There were a significant positive correlation of global citizenship(r=.364, p<.01), self leadership(r=.372, p<.01) and the global citizenship of nursing students showed a significantly positive correlation of self leadership(r=.463, p<.01). Therefore, on the result of this study, when we develop the educational programs to increase the global health competencies for nursing students, we have to include global citizenship and self leadership.

The main aim of this article is to examine theoretical issues on the 'global-local connectivity' of regional industrial cluster and regional innovation system which have been presented since the 2000s in terms of three different aspects. Firstly, the concept of 'geographical proximity' is discussed within the context of its importance for the regional industrial development by considering relationships of cluster, local buzz and global pipeline. Secondly, concepts on knowledge gatekeeper and temporary cluster are explored with respect to their role of a mediator in forming or transforming global-local connectivity. Finally, policy implications of the global-local connection are presented. Authors arguments are as follows; firstly, in order to improve regional industrial cluster on the basis of geographical proximity, relational proximity which is beyond different spatial scales has to be secured. It means that geographical convenience and inconvenience are required simultaneously for regional industrial development. Secondly, A base of the global-local connectivity is socal capital and embeddedness. Therefore, it needs to understand that relational proximity is embedded into different culture and habit at different spatial scales. Finally, within the context of the global-local connectivity, in order to overcome spatial hierarchy by the division of labor of firms, it needs to consider the complex system which is composed of vertical and horizontal hierarchy by the spatial division of labor by firms, openness and closeness of clusters, and the scope of policies' inclusion and exclusion by central and local governments.

The purpose of this study is to analyze middle and high school technology teachers' recognition and educational need about engineering education. For this, we surveyed secondary school technology teachers. The result of this study is as follow. First, most technology teachers perceive that engineering contents are lack in technology education, therefore they recognize the needs of reinforcement of engineering contents. Second, most technology teachers perceive that present technology subject does not give positive affect to students for their own career selection on engineering field. Furthermore, they perceive that if it contained the contents of engineering in technology education, students would experience creative design and problem solving process. Third, most technology teachers perceive that they are able to teach engineering in technology education and they need the change of national curriculum and the development of engineering program contents. Fourth, they perceive that the 7~9 grade is the best grade to start to study engineering in elementary and secondary school. Fifth, they perceive that 'design', 'problem solving' and 'creative thinking' are the priority of educational needs of teaching ability and knowledge about engineering. Sixth, they perceive that the aerospace engineering, the electrical engineering, the electronic engineering, the mechanical engineering, the computer engineering and the environmental engineering are the priority of educational needs of teaching knowledge about engineering fields.

As the gravity of the issue of the global warming surfaced, environmental protection and energy conservation have become one of the most serious issues that global society faces. At the status quo, there are criticisms for not effectively educating the students although the problem is very severe. In middle school, for instance, only 10% of the school offer environmental education while only $20{\sim}30%$ of the high school offer it. As witnessed by these examples, we can infer that there are not well-structured, effective environmental education for teenagers. Recently, NIE(Newspaper-In-Education) has been used as effective means for some fields of middle and/ or high school education. If so, it also could be used for environmental education. The researches, however, on the topic of NIE on environmental education are very rare. In this study, the effect of NIE on environmental education was empirically tested. Our basic assumption is that NIE will cause differences in environmental perception; the cognition and concern. And environment education through NIE will cause the high level of cognition, concern, and practice regarding environment issue. Using simple experimental design and regression analysis, we tested the effect of NIE on cognition, and, concern of environment issue, and then, on the practice of environment-improving action. The "cognition level" did not show significant difference between the experimental group(which was exposed to NIE) and control group(which was not exposed to NIE). The "concern level" for environment showed significant difference. Finally, the "practice level" showed highly significant difference between the experimental and the control group. According to regression analysis, "concern" and "NIE"(dummy variable) was turned out to be statistically significant variables for practice of environment improving action. Therefore, we came up with the conclusion that NIE, which provides the most up-to-date information regarding the environmental status, can serve as the good supplementary mechanism for the effective environment education in the present Korean middle school curriculum system. The statistical result also suggests that each individual school needs to employ and extend NIE method in its environment education curriculum.

Recently many higher education institutes in Korea try to improve the education excellence, because there are some criticisms on the readiness of graduates for the needs of companies. We study the relationship between the satisfaction of college life and their academic achievements for freshmen during last 5 years at a certain university (so-called H University). In this paper, we study some requirements for freshmen to meet their needs to upgrade their capability throughout both curricular and extra-curricula activity and also study to improve their satisfaction of college life. We also propose some curricular and extra-curricula activity for freshmen to meet the their needs for the excellent academic achievement and to have satisfactory college life.
