This study examined in what category that the knowledge dimension and the cognitive processes dimension are described based on ``A revision o Bloom``s taxonomy of educational objectives`` in oral health education textbooks. Oral health education and practice from Educational Objectives of Dental Hygiene Department(Korea dental hygienist Prof Council, 2009) were selected to analyze a textbook, the body contents was analyzed in the knowledge dimension, and the activity was analyzed in cognitive processes dimension. Three experts were selected as a corder for reliable analysis. As a result of this study, the knowledge dimension in oral health education textbook was focused on the categories of factual knowledge and conceptual knowledge in textbook analysis based on ``A revision of Bloom``s taxonomy of educational objectives``, and the category dimension of ``understand`` showed to be the most for the cognitive processes dimension. Moreover, there was no ``meta cognitive knowledge`` that conforms to a higher-order thinking and the category dimensions of ``analyze``, ``evaluate``, and ``create`` took very low proportion or did not exist. Conclusion, Oral health education textbooks were analyzed to fragmentary and Memorizing the level knowledge. Thus we have to develop oral health education textbooks reflected a variety of cognitive and knowledge dimension.
미래문제해결프로그램을 통한 과학영재들의 창의·인성 탐색

본 연구에서는 과학영재들을 위한 창의•인성 교육 방법의 하나로 미래문제해결프로그램을 적용하여 창의적 문제해결과정에서 나타나는 특징을 살펴보고, 영재들의 자기 성찰과 과학에 대한 태도 및 창의적 인성 검사를 활용하여 미래문제해결프로그램이 창의•인성에 미치는 영향을 살펴보고자 하였다. 프로그램은 ‘기후변화’ 토픽과 관련하여 지역공동영재학급 중학교 1학년 20명을 대상으로 6회에 걸쳐 총 11차시로 진행되었다. 연구결과 학생들의 창의적 문제해결력에는 순차적으로 연관된 사고과정에 의한 문제발견이 다양한 창의적 사고 과정과 의사소통을 가능하게 하여 효과적임을 알 수 있었다. 또한 기후변화와 관련된 미래문제해결프로그램을 통해 영재들은 환경문제의 심각성과 중요성을 깨닫고 대책마련이 시급하다고 인식함으로써 과학에 대한 태도가 대체로 유의미하게 변화되었으며, 모둠활동을 통해 협동과 의사소통 등을 배움으로써 창의•인성 및 인성적 요소뿐 아니라 창의적 성향에도 효과가 있음을 알 수 있었다. 이를 바탕으로 창의•인성 교육방법으로서 미래문제해결프로그램을 효과적으로 사용하기 위해서는 문제이해단계에서 충분한 논의와 사고과정이 일어날 수 있도록 해야 하고, 토론 시 고려해야할 창의•인성 교육 요소들에 대한 지침을 제공하며, 글로벌 시민의식이나 생명존중 등 다양하고 포괄적인 관점에서 토의가 일어날 수 있도록 구성할 필요가 있음을 제언하였다. In this study, we investigated the qualities which can be found in the process of problem solving by applying the Future Problem Solving Program (FPSP) to science gifted students, and what they felt and learned from the viewpoint of creativity and character. We applied the FPSP about climate change (total 11 times run over 6 sessions) to 20 first grade students of gifted class in the local community of middle school. The results of this study confirmed that problem finding through a thinking process related in consecutive order leads to the proposing of effective solutions through the various divergent thinking processes and communications. The FPSP had positive influences in the attitude to science, and creative personality as well as character education. The science gifted students realized the importance and seriousness of environmental problem, thought the measures are urgently needed, and learned teamwork and communication skills. For creativity and character education method, this study suggested that FPSP consists of enough discussion and thinking process on problem finding, provides the guideline about creativity and character education, and presents differing perspectives about global citizenship, life respect, and so on.
Design and analysis of the lens converting the spot light into the line light

A CCFL which commonly used in the back light units for the LCD, possess very high brightness hence, was widely used as a line light source. However, the use of CCFL, caused for several environmental concerns since it contain highly toxic mercury, gradually replaced into a LED. But the LED is a spot light source, the dark area occurs in the surface of the back light units. In this paper, we proposed the lens that can convert the spot light into the line light and it can remove the dark area in the surface of the back light units. The lens is composed with the light condensation part and the light guiding part. The conditions obtained will be helpful to plan an optimum structure for such preparation.

Objectives: It will be necessary to make statement about the competence targeted in the dental hygienic education that adopts the competence-based curriculum from the standpoint of core competence which the students need to be equipped with in the society. Methods: To achieve the education objective of Dental Hygienics, the information available on the website of the Korean Dental Association, universities and graduate schools were used, and the education objectives of the concerned universities which were posted in the websites of 82 universities from July to August, 2011 were analyzed. Results: C7 and C1 accounted for 21.1%, the highest percentage, in the core capability, while HP1 comprised 79.6% in the health improvement and disease prevention. CM1 stood at 73.7%, the highest percentage, in the community involvement(CM) area, and PC4 accounted for 90.8%, the highest percentage, in the patient care(PC) area. In the professional growth and development(PGD) area, PGD1 was the highest, followed by PGD3. In relation to the comments on the occupational types after graduation, 63.1% of respondents mentioned the dental hygienists at the school, while 33.3% did not make any comment on the dental hygienists. Conclusions It was necessary to re-establish the essential objectives of the graduates based on the competence as the accomplishments of studying and learning in the department of dental hygiene. It may be a useful method to set the competency-based education objective on the basis of the implementation ability and the level of graduates.

심층수를 음용수화 하는 것은 심층수에 포함되어 있는 붕소 때문에 크게 제약을 받고있다. 붕소는 사람과 식물에게 유독한 것으로 보고되고 있다. 이러한 붕소를 제거하는 유용한 방법이 몇 가지 있는데, 본 논문에서는 해수에 포함된 붕소를 제거하기 위한 붕소제거제를 폴리머 레진 형태로 합성 하였다. 합성된 레진을 IR분석을 통해 특성을 분석하였고, SEM을 이용하여 그 표면을 관찰하였다. 붕소제거능력을 평가하기 위해 레진을 직경이 0.25mm, 0.5mm 및 1.0mm가 되도록 구분하여 준비하고 베치방식의 실험을 통해 그 결과를 관찰했다. The use of deep water as drinking water is greatly limited of significant concentration of boron in sea water. Boron is reported to be toxic for human and plants. Some of possible methods are available to remove boron. The polymeric resins were synthesized to remove the boron from the sea water. The resin was characterized with IR analysis and the morphology was discussed with SEM images. To assess boron removal capacity of the resin, it was distributed in three different bead size i.e., 0.25mm, 0.5mm and 1.0mm. The removal behavior of this resin was examined under the batch experiments.
