유럽을 중심으로 게임을 활용하는 다양한 교육 방안이 수업에 적용되고 있음에도 불구하고 국내에서 게임기반 학습(GBL) 비율은 아직 낮은 수준에 머물러 있다. 이 연구는 역사교육 GBL의 실천적 활용을 고취하기 위한 학제연구로 사례분석과 유형분류를 통하여 설계 요구사항과 학습준거, 수업모형을 도출한 후 수업에 적용하기 위한 실행 프로토타입을 개발하였다. 핵심적인 차별화 형식요소는 수업목표에 따라 교육자가 직접 지정할 수 있는 씬 관리와 역사적 전환점에 종속되도록 게임 흐름을 통제하는 개념이다. 교육자와 학습자, 교육게임 개발운용책임자로 구성된 평가단에 의한 반복적 타당성 평가를 통하여 프로토타입을 확정하였다.

This study assumes alternative character of the operation of mathematical club in middle school. The case that operated the voluntary mathematics club for one year was analyzed and the educational effect was considered. First, the examination instrument for choosing the members of mathematics club was developed and used. And, diverse teaching and learning materials for improving creativity and mathematical ability of the members were used. Second, the difference of learning result between the experiment group and control one who joined the activities of mathematics club was analyzed. Finally, mathematical club activity based on mathematics history appeared to be effective in improving academic achievement and mathematics exploration activity.

This research aimed for revealing social interaction-based environmental learning elements at the natural history museum. First, we carried out a survey of the perceptual change about 'the environment' concept. It was for confirming whether environmental learning occurred in visiting. Second, we found environmental learning elements through analyzing dialogues among small group members during looking around the museum. Social interaction-based environmental learning elements were classified into five; knowledge, affection, value, skill, behaviour. Each environmental learning element included several sub-elements, so we revealed totally 9 environmental learning sub-elements. By results, we said characteristics and possibility of the natural history museum as an informal environmental educational institution. It is meaningful for extending areas of environmental education.

The optimal surgical approach to the patients with coronary artery disease combined with carotid artery stenosis is controversial. We report two cases of successful surgical management of the patients with combined obstructive coronary and carotid artery disease. The first case was a 69-year-old female who had unstable angina pectoris and a past medical history of left carotid endarterectomy. She was revealed to have triple vessel coronary disease and nearly total occlusion of right internal carotid artery. She was undergone staged right carotid endarterectomy 10 days before coronary bypass surgery. The second case, a 54-year-old male with a past medical history of left hemiparesis and dysarthria, was admitted due to unstable angina pectoris. He was revealed to have triple-vessel coronary disease and more than 90% stenosis of left internal carotid artery and 50% stenosis of right internal carotid artery. In the latter case, a combined coronary bypass surgery and left carotid endarterectomy was done. In both cases, postoperative neurologic complications were not observed.

GBM is the most common primary brain tumor, but intraventricular GBM is rare and only few cases have been reported in the literature. The authors report a case of 64-year-old man who had a remote history of previous periventricular intracerebral hemorrhage. Brain computed tomography (CT) and magnetic resonance (MR) imaging showed an intraventricular lesion with inhomogeneous enhancement, infiltrative borders and necrotic cyst, and obstructive hydrocephalus. The patient underwent surgical removal through transcortical route via the bottom of previous hemorrhage site and the final pathologic diagnosis was GBM. We present a rare case of an intraventricular GBM with detailed clinical course, radiological findings, and pathological findings, and the possible origin of this lesion is discussed.

Among welded structure bogies in use for high speed freight car, a part of bogies manufactured in 1999 and 2000 have found problems that failure occurs in its end beam. In case of a freight car a difference of weight between empty and loading conditions are worse than in case of a passenger car. Moreover its brake system is tread brake without second suspension system. A failure of end beam is supposed to be due to loading by brake rather than vertical loading by freight. This failure can make brake system useless and may be a cause of derailment in the worst case. In this study, in order to be proved the cause of failure and to solve the problem it is described that we have measured load history acted on end beam and set up the procedures.

Man-Byeong-Hoi-Chun(萬病回春) is the principal book of Gong Tingxian who was a physician in the time of Ming(明) dynasty. It has been widely used in Korea and Japan. We recently analyzed the case reports in the book and found that he made some prescriptions by day and night separately. The method was based on the Jo-Seok-Bo-Beop(朝夕補法) by 薛己. We thought that it was an important key to his ideas in medicine. So we reviewed the origin and the basic principles of Jo-Seok-Bo-Beop and considered the clinical usages.

기업의 사회적 책임감 관련 CSR위기와 반복되는 위기에 대한 부정적인 인식이 증가하고 있다. 이런 부정적 인식에 대한 적극적 대응을 위해 선제적으로 위기정보를 공개하는 전략의 효과를 검증해 볼 필요가 있다. 본 연구는 위기유형, 위기이력, 그리고 위기공개 타이밍에 따른 전문성 신뢰와 호의성 신뢰를 분석하고자 하였다. 이를 위해 2(위기이력: 유 vs. 무) x 2(위기유형: 기업 능력 위기 vs. CSR위기)x 2(위기공개 타이밍: 선제공개전략 vs. 사후대응전략) 집단간 요인 설계 실험을 진행하였다. 연구 결과, 위기유형과 위기이력의 상호작용이 전문성 신뢰에 유의한 상호작용을 미쳤다. CSR위기 상황에서 위기이력이 있는 경우의 전문성 신뢰가 위기이력이 없는 경우보다 낮게 나타났다. 위기공개 타이밍은 위기이력, 위기유형과 상호작용을 보였다. CSR위기와 위기이력이 없는 경우의 선제공개전략 사용이 기업 능력 위기와 위기이력이 있는 경우에 비해 호의성 신뢰와 전문성 신뢰를 높이는 것으로 나타났다. CSR위기의 경우 선제공개전략의 효과가 기업 능력 위기보다 높게 나타난 결과를 고려하여 본 연구는 향후 CSR 위기 대응시 언론 공개 이전의 적극적 위기정보 공개에 대한 제안점을 제시한다.

In this study, 3 kinds of models about bike frame are simulated with static structural analysis, And fatigue life, damage and durability according to fatigue load are analyzed. A bike frame model with diamond type is compared with another model on the reinforced support with its type. In case of the reinforced support type, maximum equivalent stress or total deformation is shown with 10% or 20% more than the diamond type respectively. At both types of models, the trends of fatigue life and damage at both types are same. 'SAE bracket history' with the severest change of load becomes most unstable but 'Sample history' becomes most stable among the cases of nonuniform fatigue loads. In case of 'Sample history' with the average stress of 0 to -1MPa and the amplitude stress of 0 to 1MPa, the possibility of maximum damage becomes 3%. This stress state can be shown with 6 times more than the damage possibility of 'SAE Bracket history' or 'SAE transmission'. In case of the reinforced support type, fatigue life becomes shorter and damage probability becomes larger at the right side installed with support than diamond type. The structural result of this study can be effectively utilized with the design on bike frame by investigating prevention and durability against its damage.
