Purpose: Implant engine system is composed of the handpiece, micromotor, control box and foot switch. The aim of this study was to evaluate the satisfaction of the implant engine systems in terms of convenience-design and to examine the relation with the experience of implant surgery. Materials and Methods: Three implant systems were evaluated: SurgicXT/X-SG20L, INTRAsurg300/CL3-09, XIP10/CRB26LX. For this comparative study, 30 dentists were included and the satisfaction was measured using a structured questionnaire. One-way analysis of the variance (ANOVA) and multiple regression analysis were used within and between the groups. Results: Total satisfaction differed from each other (P < 0.05). The convenience score was more associated with the total satisfaction than design score. Moreover, the implant surgery experience affected several assessments. Conclusion: Collectively, in a cross-sectional study model, the design of implant system significantly affects its total satisfaction and the surgery experience can be influential factor in the evaluation of implant engine system.

New design method has been required for web designers to grasp the proper emotion, impression, and feeling of a web site and reflect these elements in web design. It is certain that such a new methodology can be a useful design tool, although web designers have only relied on their intuition and experience to induce users to perceive specific emotion of web sites. In this study, Kansei Engineering Type Ⅰ (Nagamachi, 2002 and Park, 2000) method was applied to develop the methodology. One hundred thirty six web sites believed to convey emotions effectively were first selected by recommendation of professional web designers and twenty two web sites were finally chosen and evaluated using questionnaire. The web sites were then objectively and quantitatively assessed by measuring the degree of utilization of the design elements, balance, overall density, and homogeneity. We examined the cause-and-effect between the results of emotional and quantitative analysis by multiple regression and introduced the design methodology based on the examination. The research method and procedures applied to this study would be applicable to design studies related to the emotional inducement.

Rapid prototyping technology has been widely applied to the design process in the industry. This technology made it easy to generate a prototype which acts like a real product in logic. However, this technology has not been validated sufficiently as a usability test method. The purpose of this study was to test the hypothesis : There was no significant difference between a real product and its prototype. An experiment was designed to test it statistically. a microwave oven was selected and its prototype was generated using a rapid prototyping tool. Six subjects used the microwave oven and another six subjects used the prototype to perform five scenario tasks. As a result, there was significant difference between the real product and prototype in success rate, task completion time, and number of buttons pressed. The prototype was more difficult to operate than the real product. Therefore we should be careful when we apply rapid prototyping. technology. In the discussions, the causes of the difference were identified and some guidelines were suggested for who wants to apply rapid prototyping tool to the usability test.

Creativity has very important significance to children. Although active researches and educations on other studies (for instance, mathematics, science, logics, music, etc) are being done, evaluation or development on children's creativity in design is very inadequate. Therefore, this study is a basic research to develop evaluation to judge design creativity of children as an incipient stage of educational method development to develop children's creativity in design. Evaluation categories (originality - novelty/fun, practicality-function/possibility) that can evaluate design creativity of children were drawn out based on documentary records, and as the results or performing experimental research to figure out correlativity between creativity of idea and design creativity targeting children in second grade of elementary school, subordinate provinces of idea's creativity related to design creativity were fluency and elaboration. However, it does not mean that fluency and delicacy are the only subordinate provinces of idea's creativity related to design creativity, but they are more influential compared to other provinces (creativity, abstractness of title, and resistance to premature closure) This study is to prepare basic framework of educational method to improve design creativity education of children, and has its meaning to complement what are lacked in design creativity through the educational method.

Diverse disciplines such as information science, computer science, cognitive science, and industrial design, are activity engaged in the website evaluation research efforts. Information scientists emphasize the importance of user-centered and user-friendly website design, which is also easy to use, This idea is based on the understanding that the users and the designers are different set of people. In addition, information scientists consider the practice of maximally incorporating user inputs during the website design to be very important guideline. However, this study is based on a newly emerging population of website users who are also designers. 218 study participants evaluated the websites that they designed in comparison to the websites designed by others. According to the survey data analysis, the study participants considered the content delivery, design simplicity, design consistency, and link access of the websites to be equally important from both users' and designers' perspectives. However, the content organization, rich content, and screen composition were underestimated from the designers' point of view whereas these factors were considered to be important from users' point of view.

It was applied by making the models such as the prior learning (e-learning), modeling by manual, learner's practice, 1:1 teaching coaching, self evaluation, coaching behavior assessment(primary, secondary), and self-directed practice. First, the cognitive practice education through the prior learning is very essential in the practice of floral design. Second, the practice class of floral design is a class where the professor generally set an example first, and the learners followed. Third, this study was to prepare the checklist, reflect it through the self evaluation, and prepare the evaluation form in accordance with the element, principle, and technical parts of floral design about the finished works. Fourth, contrary to the existing class completing within the class hour, the practice class is a process of trying to do self-directed practice, returning to home. Fifth, this study was to evaluate the works the learner made once again through the sketching and photographing by placing the work process of portfolio at the last step. To conclude, this study has found that such series of process through six steps on the practice form by the learner only would be excellent teaching learning model to improving the basic capacity of floral design. Accordingly, the development of teaching materials related to this and adaptation in the field in the future is considered as it will be very helpful to the learners' self-directed learning.

Children will present phobic psychology in the special environment in hospital. Therefore, children's psychological emotions should be taken into account in the construction of the hospital environment. After that, the three stages and seven emotional factors which stimulate children's emotions will be summarized and applied to the graphic performance in children's hospitals, so as to alleviate children's fear. Plus, through the analysis of domestic and foreign cases, the graphic representation types of children's hospitals are divided into modern design, illustration design, three-dimensional design, interactive design, and these emotional factors are integrated into the graphic representation for evaluation. Here comes the evaluation results: there are little or no emotional factors in modern design; there are less emotional factors in illustration design and three-dimensional design due to less feelings and experiences. However, the results show that children feel much better from all aspects because there are more emotional factors with the help of interactive design. Based on the above evaluation results, here comes the graphic design guidelines for children's hospital waiting room.
