The creative fashion design is the technique which ran be obtained through the structural analysis of the relationship between principle, element-combination and idea-expression. In the research, as the results of theoretical survey of design structure and idea-expression, the structural and subjective designs are classified and defined: a. the structural design is analyzed with the existing examples based on the combinational Idea-expression of the O.C.L method, and b. the subjective design is also analyzed connecting the real examples to Cordon method, Synetic method, Association method, and expansive idea-expression-method obtained by the Experiences of Geometrical Combinations. The research can be summarized as follows: 1. The creative fashion design which emphasizes the geometrical structure utilizes the modification method whirh combines the shapes and constructs extraordinary structural beauty coming from the complex structural principle, that is, emphasis and balance. 2. The creative fashion design which emphasizes specific subjects utilizes the modification method which mimics representative and plastic resemblances and constructs symbolic structural beauty coming from the simple structural principle, that is, material elements.

The purpose of this study is to investigate the effect of STEAM program on students' academic achievement, creative problem-solving ability, scientific inquiry ability and scientific interests of elementary school students. For this, we developed a STEAM program to utilize animation production about 'structure and function of the our body' unit in 5th grade. The STEAM program was developed for a total of 9 sessions and was applied to the experimental group. The theoretical lesson of the 2009 revised curriculum was consisted of 11 sessions and was applied to the comparative group. The results of study showed significant differences of the students' academic achievement, creative problem-solving ability to the experimental group participating in the STEAM program and also showed significant effects in the domains of subject contents and teacher preference, which are the areas of scientific interests compared to the comparative group. This means that the STEAM program to utilize animation production about 'structure and function of the our body' developed in consideration of the characteristics of elementary students positively influenced the academic achievement, creative problem-solving ability and scientific interests of elementary school students. In the future we need to develop STEAM programs more variously that utilize animation production and that it needs to be applied to elementary schools.

3-Hydroxybutyryl-CoA dehydrogenase is an enzyme that catalyzes the second step in the biosynthesis of n-butanol from acetyl-CoA, in which acetoacetyl-CoA is reduced to 3-hydroxybutyryl-CoA. To understand the molecular mechanisms of n-butanol biosynthesis, we determined the crystal structure of 3-hydroxybutyryl-CoA dehydrogenase from Clostridium butyricum (CbHBD). The monomer structure of CbHBD exhibits a two-domain topology, with N- and C-terminal domains, and the dimerization of the enzyme was mostly constituted at the C-terminal domain. The mode of cofactor binding to CbHBD was elucidated by determining the crystal structure of the enzyme in complex with $NAD^+$. We also determined the enzyme's structure in complex with its acetoacetyl-CoA substrate, revealing that the adenosine diphosphate moiety was not highly stabilized compared with the remainder of the acetoacetyl-CoA molecule. Using this structural information, we performed a series of site-directed mutagenesis experiments on the enzyme, such as changing residues located near the substrate-binding site, and finally developed a highly efficient CbHBD K50A/K54A/L232Y triple mutant enzyme that exhibited approximately 5-fold higher enzyme activity than did the wild type. The increased enzyme activity of the mutant was confirmed by enzyme kinetic measurements. The highly efficient mutant enzyme should be useful for increasing the production rate of n-butanol.

The purpose of this study is to plan a environment for creative education in university campus. According to the literature review, the necessity of improvement of educational program and physical environment is increasing because of rapidly social and industrial structure change. In this aspect, G university decided to make space for creative education utilizing unused space in campus. The space design concept was established as a cell based on the fact that the educational space was a place where students grow up and was named GNU IDEA Factory. The planning site was decided on the existing piloti to solve problems of lack budget and space. This space consisted of rooms for creative education, autonomous students' activity, and exhibition and was designed by organistic structure. In conclusion it was thought that GNU IDEA Factory would be a case of environment for creative education and activity if it was supported proper program and usable equipments.

A high-speed traveling-wave photodetector (TWPD) with an InGaAs absorber is designed and realized. The bandwidth of the TWPD is measured using electro-optic sampling techniques. The bandwidth is 410 GHz, which shows that the RC limitation is overcome. While the TWPD shows a low responsivity of 0.06 A/W at 1,550 nm, this value can be improved through further optimization of the structure without a sacrifice in bandwidth.

Piaget's revolutionary study on the cognitive development of children has focused on the development of logic. Logical operations and a variety of classifications based on the set of accepted rules involve convergent thinking. Children and adults have logical and creative thinking which deal with a reality of thinking. This study aims to examine a cognitive structure of students, which is closely related to the Piaget's cognitive development theories of students when creative thinking. Students were given an open mathematical problem and were expected to be able to take advantage of sensitivity, fluency, flexibility, originality, and elaboration which can be seen as clearly of their structure cognitive.

This paper attempts to review some key concepts related to the creative economy, and examines some issues on the creative economy and regional development from the perspective of economic geography. The main findings are as follows. First, as creative industries, in general, demonstrate the complex structure of value chain in which various industrial sectors are inter-connected, it tends to show that those are place-specific. Second, in policy context, creative industries are required to have four institutional conditions: hard infrastructure(physical infrastructure, skilled labor pool and related industrial sectors), social infrastructure, super-structure and policy governance. Third, as creative industries are affected by related variety than other industrial sectors, there is a strong possibility that those are concentrated in a small number of large metropolitan cities.

Corynebacterium glutamicum (C. glutamicum) has been considered a very important and meaningful industrial microorganism for the production of amino acids worldwide. To produce amino acids, cells require nicotinamide adenine dinucleotide phosphate (NADPH), which is a biological reducing agent. The pentose phosphate pathway (PPP) can supply NADPH in cells via the 6-phosphogluconate dehydrogenase (6PGD) enzyme, which is an oxidoreductase that converts 6-phosphogluconate (6PG) to ribulose 5-phosphate (Ru5P), to produce NADPH. In this study, we identified the crystal structure of 6PGD_apo and 6PGD_NADP from C. glutamicum ATCC 13032 (Cg6PGD) and reported our biological research based on this structure. We identified the substrate binding site and co-factor binding site of Cg6PGD, which are crucial for understanding this enzyme. Based on the findings of our research, Cg6PGD is expected to be used as a NADPH resource in the food industry and as a drug target in the pharmaceutical industry.

The purpose of this study was to compare problem finding ability, creative thinking ability, creative tendency, and science process skill between the scientifically gifted students and the general students. For this study, problem finding ability test, integrating creativity test, and science process skill test were conducted to the elementary gifted students (n=95) in science and the general students (n=149) at the same school district. The results of this study were as follows: The mean scores of problem finding, creative thinking, creative tendency, and science process skill of the gifted students were statistically higher than the general students. The problem finding ability had partially weak correlation with sub-domains of the creative thinking ability, creative tendency, and science process skill. Findings suggest that there are needs of further study about factors affecting problem finding and considering the degree of structure of problem situation.
