It is very necessary to know about child recognition of residential environment to plan and design an environment proper for children's growth and development. The research method using Cognitive Map, which may be defined as "an overall mental image of representation of the space and layout of a setting" can be a good tool for studying child recognition of residential environment. This study analyzed the child recognition of the size of home range, the number of residential environment elements, the types of Cognitive Map and the levels of Cognitive Map to understand the contents of child recognition about their residential environment. Subjects were 206 children in age6, 8 and 10 in Gwanju and Jeonnam area. As the result of the study, we found that 70% of child recognized 100~500 M as the size of home range, and that the number of the elements of residential environment was 7, average. And we also found that sequential map was more popular than spatial map in child's Cognitive Map type and that almost 60% of child respondents drew the Cognitive Map of level 1 complexity type. As the result of this study, we could know that the research method using Cognitive Map was very useful for understanding the child recognition of residential environment.

In this study, tests of brain waves were carried out to investigate the driver's physiological characteristics by the change of the headlight. The participants were 20 men in their 20s and twenty-three different conditions in combinations of waveform of light, voltage, and alteration time were used. The measurement of the brain waves was performed by internationally standardized 10-20 method using LXE3232-RF. The results were analyzed by Power Spectrum Analysis using alpha-, and beta-wave and by the analysis of different brain domains using Brain wave Map. The results were as follows. 1. From the results of the Brain wave Map analysis, it was suggested that A waveform increases mental stress and B waveform affects mental and visual stress. The longer the stimulation time, the more stress level was detected. 2 The voltage alteration time of B waveform should be kept less than 1500msec, and the voltage should not fall below 11.5V.

This Study discuss exploring normative-prescriptive factors after the themes on Organizational learning categorize two descriptive/explanatory-perspectives, prescriptive/normative dimension. The former would contain information processing model, theory of action, organizing in organization, while Senge's suggestion on Learning Organization may compose the latter. Each perspective is reconstructed and reinterpreted into the causal mapping relationship founded on system thinking and SD. Underlying on the former try to discovery validities of the latter. But this study only put forward the integral-dynamic model of organizational learning without empirical simulation.

최근 과학교육에서 학생들이 현재 가지고 있는 개념의 특성을 분석하고 개념형성에 영향을 미친 요인들을 확인하며 이들 요인들이 개념변화과정에 어떠한 영향을 미치는지에 대한 심층적인 논의의 한 가지 이론적 배경으로 정신모형에 대한 관심이 높아지고 있다. 정신모형이란 학습상황에서의 외부 정보와 장기기억 속에 저장되어 있는 지식과 믿음 사이의 상호작용의 결과로서 작업기억 속에 형성된 역동적인 표상이다. 따라서 문제 상황에서 형성된 정신모형과 정신모형 형성과정을 조사하는 데에는 학생의 인식론적 신념, 존재론적 신념, 메타인지 등 인지적 요인, 동기, 불안, 목표 등의 정의적 요인, 수업, 제시된 과제 등의 맥락요인과 같이 다면적인 접근을 시도할 수 있다. 이에 본 연구에서는 학생들의 원운동 정신모형 형성에 영향을 미치는 관련 변인들을 사례연구와 문헌연구를 통해 확인한 후, 윈운동 단원을 가지고 정신모형 이론에 기반 한 수업모형을 개발하여 경기도 소재의 인문계 고등학교 2학년 물리수업에 적용한 후, 이 수업에 참여한 한 학생의 수업 전, 직후, 지연 사후의 각 시기마다 이 학생이 원운동 문항에 관해 어떤 정신모형을 형성시켰는지, 그리고 각 시기를 거치면서 원운동 문항에 관한 정신모형이 어떻게 변하였으며 이에 영향을 미친 요인들에 관해 알아보았다. 사례 분석 결과, 학생들이 각 시기의 문제 상황에서 떠올린 정신모형은 통합된 정신모형 이론에서 논의한 바와같이 수업이전 획득한 관련 지식과 인식론적 신념 등과 같은 인지적 요인, 과학학습에 대한 흥미 등의 정의적 요인, 메타인지 활동 등을 강조한 교수전략이 사용된 수업 등의 맥락요인들이 역동적으로 상호작용한 결과로 형성된 것임을 확인할 수 있었다. 한편, 겉으로 표현된 정신모형은 수업 후 어느정도 변화가 가능한 것으로 확인되었으나, 인식론적 신념과 같은 부분은 수업후에도 쉽게 변화지 않음을 알 수 있었다.

Objectives Children are one of the most vulnerable populations to the impact of disasters. We aimed to examine children's mental health in the area affected by the Hebei Spirit oil spill accident on December 7, 2007. Methods A cross-sectional questionnaire survey was conducted using the Korean versions of the Children's Depression Inventory and State Anxiety Inventory for Children on 1,362 children attending elementary schools in the affected area. The information on distances between the nearest contaminated coastline to the child's residential house or attending school were obtained using a web-based map by inputting two address points. The symptom risks of depression and state anxiety were estimated by multiple logistic regression analyses adjusted for age, gender, and other covariates. Results Children with the closest distance (in the fourth quartile) to the school from the contaminated coastline showed a significantly higher symptom risk of depression compared to those with the farthest distance (first quartile)(odds ratio, 2.73; 95% confidence interval, 1.40-5.33), while there was no significant association between anxiety symptoms and distance. Conclusions Children, a vulnerable population for mental health impact by the oil spill accident, should be included in mental health programs in the community along with their family as victims of the disaster.

A previous animal study has shown the effects of erythropoietin (EPO) and its non-erythropoietic carbamylated derivative (CEPO) on neurogenesis in the dentate gyrus. In the present study, we sought to investigate the effect of EPO on adult hippocampal neurogenesis, and to compare the ability of EPO and CEPO promoting dendrite elongation in cultured hippocampal neural progenitor cells. Two-month-old male BALB/c mice were given daily injections of EPO (5 U/g) for seven days and were sacrificed 12 hours after the final injection. Proliferation assays demonstrated that EPO treatment increased the density of bromodeoxyuridine (BrdU)-labeled cells in the subgranular zone (SGZ) compared to that in vehicle-treated controls. Functional differentiation studies using dissociated hippocampal cultures revealed that EPO treatment also increased the number of double-labeled BrdU/microtubulea-ssociated protein 2 (MAP2) neurons compared to those in vehicle-treated controls. Both EPO and CEPO treatment significantly increased the length of neurites and spine density in MAP2(+) cells. In summary, these results provide evidences that EPO and CEPO promote adult hippocampal neurogenesis and neuronal differentiation. These suggest that EPO and CEPO could be a good candidate for treating neuropsychiatric disorders such as depression and anxiety associated with neuronal atrophy and reduced hippocampal neurogenesis.

이 연구에서는 기존의 지능형 교수기계와 또래 튜터링의 단점을 보완하여 '가르치기를 통한 학습'을 위한 교수가능 에이전트(Teachable Agent, 이하 TA) 의 이론적 배경 및 설계방안을 제시하고자 한다. TA는 학습자가 컴퓨터 에이전트를 가르치는 과정을 통해 학습하는 시스템으로 교수 Module, 묻고 답하기 Module, 테스트 Module, 학습자료 Module 등의 4 가지 Module로 구성된다. 교수 Module에서는 개념도(concept map)의 구성을 통해 튜터 역할을 하는 학습자가 TA 의 심성모형 (mental model)을 수정하고 update하게 되며, 묻고 답하기 Module에서는 인터렉티브 창을 통해 튜터와 TA가 제한된 방식으로 학습내용에 관한 질문과 응답을 함으로써 개념도를 수정보완하게 된다. 테스트 Module에서는 튜터가 가르친 TA가 미리 정해놓은 학습목표에 도달하였는지를 평가하게 된다. 테스트 결과 TA가 일정 수준에 도달하지 못한 경우에는 개념도의 재수정 과정을 통해 계속적인 학습이 이루어지도록 한다. 학습자료 Module은 튜터가 참고할 자료를 제공해 주는 Module이다. 이러한 TA는 튜터의 역할을 담당하는 학습자에게 깊이 있는 인지적 처리와 능동적인 학습동기를 경험하도록 함으로써 실제 교육현장에서의 유용한 교수/학습도구로 활용될 수 있을 것으로 기대된다.

Personal Digital Assistants (PDAs) have become ubiquitous and continued to gain popularity. Since PDAs have some special contexts such as mobility and limited screen size, icons are utilized frequently because icons allow us to do tasks more rapidly and effectively on PDAs like another information appliances. The study presents a cognitive approach to study human factors affecting icon design with multidimensional Scaling (MDS) analysis. In the experiment, a real PDA was used to investigate 29 attributes and2 preference ratings for 22 PDA icons by 20 Korean subjects. As a result, cognitive positioning about icons, attributes, and preference data were arranged on the two dimensional perceptual map. Attributes were grouped by simplicity, universality, activity, complexity, abstraction, static, and alphanumeric time. Subjects preferences were highly related with simplicity attributes group and positive to universality and activity attributes groups. It was also confirmed that there are some icons unfitted to the mental model of Korean. However, when icons are designed for PDAs or similar information appliances to Korean, it should be designed simply and actively with universal image fitted on target users mental model.
