강남콩의 지방질을 chloroform-methanol-water (1:2:0.8, v/v)의 용매로 추출하고 이를 silicic acid column chromatography에 의하여 중성지방질, 당지방질 및 인지방질로 분획한 다음 이들의 지방질 조성과 지방산 조성을 TLC, GLC에 의하여 분리 정량하였다. 강남콩의 총지방질 함량은 1.9%이었으며 이중 중성지방질은 48.2%. 당지방질은 7.5%, 인지방질은 44.3%이었다. triglyceride는 중성지방질중 64.6% 함유된 주성분이었으며 가장 함량이 높은 인지방질과 당지방질로서 phosphatidyl choline은 인지방질중 32.9%, esterified steryl glycoside는 당지방질중 38.8% 함유되어 있었다. 강남콩의 주요 지방산은 linolenic, linoleic, oleic, palmitic acid이었으며 특히 linolenic acid는 그 함량이 높아 총지방질의 경우 37.1%, 중성지방질의 경우 50.4% 함유되어 있었다. Lipids of kidney bean were extracted by the mixture of chloroform-methanol-water (1:2:0.8 v/v), fractionated into neutral lipids, glycolipids and phospholipids by silicic acid column chromatography, and the composition of these lipid classes were determined by TLC and GLC. The lipid content of kidney bean was 1.9%, and the lipid was consisted of 48.3% neutral lipids. 7.5% glycolipids and 44.2% phospholipids. Triglyceride was the major component of neutral lipids (64.6%). The major glycolipid and phosphlolipid were esterified steryl glycoside (38.3%) and phosphatidyl choline (32.9%). The major fatty acids of kidney bean lipid were linolenic, linoleic, palmitic and oleic acid. Linolenic acid contents were very high to be 37.1% in total lipid and 50.5% in neutral lipid.

Objectives: This study aimed to evaluate any clinical studies regarding the herbal medicine for dementia focusing on Korean literature for future rigorous clinical research. Methods: Every article relevant to dementia was initially obtained from oriental medical related journals by electronic search at journal web sites or manual searches. Journals were limited to those registered with the Korea Research Foundation. From initial findings, two independent reviewers selected clinical articles and these articles were further analyzed separately by predefined criteria according to prospective and retrospective studies. For randomized controlled trial and non randomized controlled trial, quality assessment was also conducted. Results: From ninety seven patients initially obtained articles, twenty three patients were finally analyzed. One article was randomized controlled study, Four articles were prospective whereas eighteen patients were retrospective. In the qualitative evaluation of prospective articles, there was deduction regarding pre-calculated study size and prospective data collecting. Assessment measurement most frequently used was Mini Mental State Examination. The order of frequency of use herbs were identified. Conclusions: According to our study, the herbal medicine for dementia in general showed a positive effect in the cognitive aspects of dementia patients. Further well-designed randomized controlled studies should be conducted.

우리는 기능성자기공명영상을 이용하여 생물전공 및 비전공 예비교사들과 생물학자들의 가설 생성 및 이해에서 나타나는 두뇌 활성 차이를 검증하고자 하였다. 이를 위해 우리는 생명현상에 관한 두 세트의 과제 패러다임(가설생성 및 가설이해)을 설계한 뒤, 36명의 건강한 연구 참여자들(각 집단별 12명)과 함께 이 연구를 수행하였다. 이 연구의 결과는 첫째, 생명현상에 대한 가설생성에서 나타나는 두뇌활성 패턴에 있어 세집단 간의 유의미한 차이가 발견되었다. 둘째, 배외측 전전두피질부의 한 부분인 좌측 중전두이랑이 세 집단 모두에서 가설생성에 있어 중요한 역할을 하고 있다는 것이다. 또한 생물학자들에게서 나타나는 우수한 가설생성능력은 2차적인 추상정보의 통합 기능을 하는 좌측 중전두이랑의 활성에의한 것으로 판단된다. 셋째, 생명현상에 대한 가설이해 과정에서는 세집단 간의 유의미한 두뇌활성 패턴차이가 발견되지 않았다. 이러한 결과들은 과학자들이 새로운 과학적 지식의 생성에 있어 숙련되어있다는 것을 보여주고 있다. We aimed to examine difference between the brain activation pattern based upon hypothesisgenerating and hypothesis-understanding among the pre-service teachers not majoring in biology, the pre-service teachers majoring in biology and the biologists using fMRI. We have designed two sets of task paradigm on the biological phenomena: hypothesis-generating and hypothesis-understanding and thirty six healthy participants (twelve participants per group) performed the tasks. The result was showed that 1) there were significant differences of brain activation patterns in hypothesis-generating on the biological phenomena among three groups, 2) the left middle frontal gyrus in the part of DLPFC region was play an important roles of hypothesis-generating and make a significant differences among three groups. The superior ability of biologists were based upon the activation of middle frontal gyrus which has secondary integration of abstract information, and 3) there were no significant differences of brain activation patterns in hypothesis-understanding on the biological phenomena among three groups. These findings provided that scientist might be skillful in generating a new scientific knowledge.

The purpose of this study was to suggest an advanced system for educating scientifically gifted children in the Center for Science Talented Education at Kyungpook National University. Several suggestions based on analysis of current identifying-process and instructional materials for scientifically gifted children were provided for advancing the educational system of the center. First, this study suggested a three-step procedure to identify procedure emphasized students reasoning skills as one of important characteristics of the gifted child. Second, this study provided an instructional model for developing hypothesis testing skills in scientifically gifted children. The model was originally based on Lawson's scientific reasoning processes and learning cycle mode. Third, this study also suggested an effective administration system of the Center for Science Talented Education. Further, this study suggested effective ways on research works for advancing the center, educating instructors, the cyber center for remote education, and international co-works for developing the gifted children's potential abilities.
