At the beginning stage of design process, the concept design is required to equip the creative idea thinking and exerts critical effect on the success of production. To support the idea thinking process at the stage of concept design, web-based Creative Group Thinking System(CGTS) was developed. In this vein, the purpose of this study is to investigate the significance of HCI(Human Computer Interface) and UI(User Interface) and to find the way to increase the applicability of the UI of CGTS.

Interfaces comprising menu and icons of web-based application programs should comply pertinently with user's cognitive system. In Particular, since the application Program's specific function in this study aimed at the purpose of child's effective idea, with respect to that, it is necessary to constitute a rational web use environment through careful research and analysis of user interface. The purpose of this study was to enhance elementary students to modify the CGTS with the menu arrangement. icon types and preferable terms for their use of professionally letter-based screen structure of CGTS developed to help the designer's idea.

The primary concern here is to discover the what and how of the computer same development. In other words, the goal of this research is help the evaluation of Creative Croup Thinking System (CGTS), become aware of areas of need for the development computer game. For the development computer game, the creative thinking is one of the most important principles. The creative thinking is the first step of the development computer game of process. In order to save time, effective qualifies, and achieve the goals, the researcher has studied the web programing on the Creative Croup Thinking System (CGTS).

The success or failure of a game depends on its creativity. Especially during the first period of the process. For this reason, requesting CGTS(Creative Group Thinking System) -previously developed system based on web- in the scenario process of the game designing development. In accordance, this study is to program the thinking performance in result of increasing creativity obect to shortening working hours.

A series of PLA-PEO-PLA triblock stereo-copolymers with varying PLA/PEO and L-DL-LA ratios were synthesized via ring opening pelymerizations. Aqueous solutions of these copolymers undergo thermo-responsive phase transitions as the temperature monotonically increases. Further study shows that there is a critical gel concentration (CGC), and also lower and upper critical gel temperatures (CGTs), at which the thermo-responsive phase transition occurs. The CGC and CGTs are affected by various factors such as block length, as well as the compositions of the PLA blocks and of the additives. In particular, the changes in the phase diagram produced by varying the L-/DL-LA ratio in the PLA blocks were determined to be mainly due to consequent stereo-regularity changes in the PLA blocks.

WEB or Internet has given mankind an unprecedented experience in indefinite sharing of online content by original means of digitalized information, but it comes to face an empirical issue of unreasonable informational superfluity as well as a practical issue of collapsed dot.com bubble economy in 2001. Instead, a latest networking concept called 'WEB 2.0' or 'Semantic WEB' becomes embodied as a new approach to entities such as end users and content. The concept of WEB 2.0 for creating a platform on the basis of openness and collaboration has made such a technological setting that we can effectively resolve and manage unreasonable data maintenance and interface inherent in Creative Group Thinking System (CGTS), a WEB-based computer-aided idea generation system developed in 2003. Concerning decreased usability and difficulties with data maintenance due to certain issues of CGTS as a part of WEB R&D platform, such as complex display composition and inefficient data processing system, this study seeks to simplify and streamline data structure by means of AJAX and DOM as WEB2.0-based technologies, and integrate interface structure of WEB platform to focus on end users, so that it can improve interface of conventional CGTS for the purpose of realizing end user's participation through improving usability.

For the expression of CGTase gene(cgtS) kom Bacillus stearothemophilus NO2 in Saccharomyces cerevisiae, cgtS gene was subcloned into the Eschepichia coll-yeast shuttle vector, pVT103-U. The constructed plasmid, pVT-CGTS was introduced to 5. cemi-siae 2805 cell, and then the cgtS gene under the control of adhl promoter was successfully expressed in the yeast transformant and 87% of the total activity was detected into the fermentation medium. Therefore, the signal peptide of B. stearothemephilus NO2 CeTase showed high secretion efficiency in 5. cerevisiae. Optimal conditions of the recombinant yeast cell f3r expression of CGTase was achieved, when 5. cerevisiae 2805/pv7-CGTS was cultivated on YP medium at 2% dextrose, pH 5.5,$30^{\circ}C$ and the expression level of CGTase was 0.624units/mL for 48 h culture.
