The purpose of this study was to analyze 181 papers about brain-based learning appeared in domestic scientific journals from 1989 to May of 2012 and suggest application conditions in elementary science education. The results of this study summarizes as follows; First, learning activity suggested by brain-based learning study is mainly explained by working of brain function. Learning activity explained by brain-based learning study are divided into 'learning according to specialized brain function, learning according to brain function integration and learning beyond specialization and integration of hemispheres'. Second, it searched how increased knowledge of brain structure and function affects learning. Analysis from this point of view suggests that brain-based learning study affects learning in many ways especially emotion, creativity and learning motivation. Third, brain-based learning study suggests various possibilities of learning activity reflecting brain plasticity. Plasticity which is one of most important characteristics of brain supports the validity of learning activity as learning disorder treatment and explains the possibility of selective increment of brain function by leaning activity and the need of whole-brain approach to learning activity. Fourth, brain-based learning brought paradigm shifts in education field. It supports learning sophistication on the understanding of student's learning activity, guides learning method that reflects the characteristics of subject and demands reconstruction of curriculum. Fifth, there are many conditions to apply brain-based learning in elementary science education field, learning environment that fits brain-based learning, change of perspectives on teaching and learning of science educators and development of brain-based learning curriculum are needed.

The purpose of this study was to examine the effects of teaching-learning programs from the perspective of brain-based learning science. Four units in 5th grade elementary science programs of the Revised 2007 National Curriculum were selected as contents to study. As the brain-based learning science analysis method, equations of the brain compatibleness index (BCI) and contribution degree on the brain compatibleness index (BCICRE) were applied to them. This study showed that there were qualitative and quantitative differences among the analyzed teaching-learning programs through the unit and curriculum. The results showed that hands-on activities like experiments or open inquiry activities improved their evaluation of the teaching-learning programs. From the analyzing, teachers can judge whether each teaching-learning program made considered the brain of the learners. Furthermore, this study can provide useful information to consult of various science teaching-learning programs brain-based learning.

인간은 보고, 듣고, 따라하고, 행하고, 느끼면서 배운다. 이 모든 과정에 뇌가 관여한다. 최근 뇌과학 연구의 비약적 발전과 뇌과학 연구와 인지과학 연구의 활발한 협력은 '뇌기반 학습과학(Brain-Based Learning Science)', '교육신경과학(Educational Neuroscience)', 혹은 신경교육학(Neuro-Education)이라 불리우는 새로운 연구 분야를 탄생시켰다. 뇌기반 학습과학은 기존의 '학습과학'을 넘어서 실제 학습과 교육환경에 적지 않은 변화를 줄 것으로 기대되는 만큼 그 가능성에 대해 회의적인 입장도 공존하고 있다. 이 논문에서는 뇌기반 학습과학의 정의와 기본가정을 살펴보고, 인지신경과학의 최신 연구가 어떻게 이루어지고 있는지를 소개하고 이러한 연구결과에서 교육적 함의를 도출해 보고자 하였다. 또한 신경계에 대한 신화적 사고와 그 문제점을 열거하고, 뇌과학과 학습-교육 현장의 연계 가능성 및 향후 뇌기반 학습과학의 전망과 한계에 대해 논의하였다.

Objectives : This study aimed at evaluation of the effects of Gastrodiae Rhizoma on brain edema and aquaporin water channel expressions in the brain. Methods : Brain edema following intracerebral hemorrhage (ICH) was induced by the stereotaxic intrastriatal injection of bacterial collagenase type VII in Sprague-Dawley rats. Then ethanol extract of Gastrodiae rhizoma was treated once a day for 3 days. Brain edema % and water contents, and cell size of neurons in the cerebral cortex were examined. Immuno-histochemistry was processed for AQP4, AQP1, and AQP9 expressions in the brain sections and area % of immuno-labeling was analyzed with image analysis. Results : 1. Ethanol extract of Gastrodiae Rhizoma reduced brain edema of ICH induced rats significantly. 2. Ethanol extract of Gastrodiae Rhizoma reduced excessive brain tissue water contents of ICH induced rats significantly. 3. Ethanol extract of Gastrodiae Rhizoma reduced cellular edema of neurons in cerebral cortex of ICH induced rats significantly. 4. Ethanol extract of Gastrodiae Rhizoma reduced AQP4 immuno-positive area % in cerebral cortex and external capsule of ICH induced rat brain significantly. 5. Ethanol extract of Gastrodiae Rhizoma reduced AQP9 immuno-positive area % in glia limitans externa of ICH induced rat brain significantly. Conclusions : These results suggest that Gastrodiae Rhizoma reveals protective effects against brain edema and cytotoxic edema of neurons by means of down-regulation of AQP4 expression in the brain.

Novel antibacterial oxazolidinones bearing pyrrolidinone ring system at the C-5 side chain were synthesized and their in vitro antibacterial activities were evaluated. Most of the synthesized oxazolidinones showed good antibacterial activity against the Gram-positive and Gram-negative bacteria tested.

The role of 5-hydroxytryptamine $(5-HT)_1A$ receptor activity in prenatal ischemia was studied, by injecting 8-hydroxy-dipropylaminotetraline (8-OH-DPAT; $50{\mu}g/kg,$ s.c.), a $5-HT_1A$ agonist on gestation day 17, and 30 min later inducing transient ischemia by ligating the uterine vessels for 30 min. On postnatal day 95, rats that had experienced prenatal ischemia showed impaired motor coordination and reduced concentration of 5-HT in the cerebellum compared with Sham-operated controls. In addition, they showed increased $5-HT_1A$ receptor densities in the cerebral cortex. Pretreatment with 8-OH-DPAT ameliorated the behavioral and neurochemical sequelae measured in the present study. The results suggest that $5-HT_1A$ receptors protect the brain from ischemic insult and/or facilitate recovery after prenatally experienced ischemia.

14-3-3 proteins are mostly expressed in the brain and are closely involved in numerous brain functions and various brain disorders. Among the isotypes of the 14-3-3 proteins, 14-3-3γ is mainly expressed in neurons and is highly produced during brain development, which could indicate that it has a significance in neural development. Furthermore, the distinctive levels of temporally and locally regulated 14-3-3γ expression in various brain disorders suggest that it could play a substantial role in brain plasticity of the diseased states. In this review, we introduce the various brain disorders reported to be involved with 14-3-3γ, and summarize the changes of 14-3-3γ expression in each brain disease. We also discuss the potential of 14-3-3γ for treatment and the importance of research on specific 14-3-3 isotypes for an effective therapeutic approach.
