In this study, synthesis of a hydrogel consisted of a coordination bond network between small organic molecules and transition metals had been carried out. By adding a tackifying material to the gel, the potential of the gel to be used as an adhesive material had been also confirmed. Synthesis of the adhesive had been done with simple mixing of 3 components: tannic acid, transition metal, and polymer. The tannic acid molecule possesses multiple hydroxyl groups that can form coordination bonds with the transition metals and hydrogen bonds with the hydrophilic polymers. Due to the morphology of the metal-organic complex and polymer dispersed in water, the fabricated material exhibited high adhesiveness and cohesiveness. Optimizing the rheological property had been conducted for use in adhesive by the synthesis with varying the transition metal (Fe³⁺, Ti⁴⁺), polymer, and treatment conditions. Rheological measurement results demonstrate the promising potential of the material as a bio-compatible and versatile pressure-sensitive adhesive with both high adhesiveness and cohesiveness.

Objectives : The purpose of this study was to examine the problems with the current practical examination, to suggest some of the right directions for that and to facilitate the improvement of the exam. Methods : The subjects in this study were the selected professors involving professors in charge of practice and the selected clinical dental hygienists who had ever served as the graders of the national practical exam. Results : A direct practical test was required in the national practical exam (77.3%), and educational facilities(79.2%)(p<0.05). They didn't put confidence in the national practical exam(81.0%) nor viewed the items about the removal and detection of dental calculus as appropriate(58.5%), either. Specifically, the items were considered to be more inappropriate by the professors in charge of practice(74.3%) than by the other professors and clinical dental hygienists(p<0.05). Concerning ways of administering the national exam, the largest group preferred that a professional evaluator should evaluate students in person by visiting their colleges(66.8%). Conclusions : The above-mentioned findings illustrated that both of the dental hygiene professors and the clinical dental hygienists thought the current national dental hygienist practical exam would absolutely be necessary since it exerted a great influence on education and educational facilities, and that the national exam should be improved to gain more confidence, to solve comprehensive problems and to ensure the efficiency of administration.

Today's elementary schools emphasize practice- and learner-based computer courses. In this research, we found solutions to the above issues by adapting a demonstration/practice teaching method led by multiple teaching assistants, expanding lessons tailored to each student's own level. We chose fourth graders from three classes at Elementary School as the subject for this research. Through this research, we have analyzed the students' study results, self-efficacy, response and interest in the computer courses by examining three groups of students: the first group led by a teacher's demonstration and practice, the second group by a teaching assistant's demonstration and practice, and the last by multiple teaching assistants' demonstration and practice. As a result, we were able to show that a computer course taught by multiple teaching assistants will help not only induce an interest and motive for a mutual learning environment among the students, but also bring positive effects on the study results and self-efficacy.

Modern design has to be satisfied to user in various social class. Therefore a study of lifestyle is vary important as a basic of design. The logical starting point to grasp the user's needs is begun by consumer analysis. There are many methods of consumer analysis, In them, the study of lifestyle is extremely much used for understanding consumer who is classified with groups. Basic education of design have to teach knowledge and ability which is to be a groundwork for designer. The study of lifestyle is not a purpose itself but one of theoretical knowledge which is requested for design. By induding practical techniques and theory, theory can be achieved through practical techniques and the meaning of theory itself could be recalled. The value of this study is in the suggestion which is the way of approach to research and to study for oneself, by introduce the study through conceptual approach for lifestyle into basic design educational program. For the study of lifestyle, let students have the theoretical knowledge which is concept of lifestyle, modern social form, consumer culture, the way of using lifestyle and theorizing lifestyle, etc, And after, let students make teams for the study of lifestyle for oneself. Every team creates the subject and studies lifestyle of each social dass by the practical way such as Inquiry, observation and interview etc. As a result they have to make a report after the form of paper and let them have a presentation in each team. Students can understand lifestyle through this process not only theoretical but also practical and can be earned an ability for apply to business.

The purpose of this study was to develop an inclusive dental hygiene practice model in an effort to stir up the self-directed learning of learners to boost their problem-solving skills and ability of providing inclusive personal oral health care in a systematic and efficient manner. The subjects in this study were 41 dental hygiene students who were in their second year in C college located in South Jeolla Province as of 2009. An inclusive dental hygiene practice was implemented during a 15-week period of time from August 31 to December 7, 2009, and a self-administered survey was conducted before and after that by using the same questionnaires. Whether there were any differences between before and after the application of the inclusive dental hygiene practice model was checked, and there was improvement in all the learning motivation, self-directed learning capabilities and satisfaction level. Concerning the relationship of academic standing to changes in learning motivation, self-directed learning capabilities and satisfaction level, the inclusive dental hygiene practice model brought more favorable changes to the students in the lower tiers. The inclusive dental hygiene model should be applied to not only practical courses but theoretical ones so that learners could make progress both in theory and practice, and evaluation tools geared toward assessing their academic achievement and practical abilities should be developed.
