수학문제해결에서 직관은 문제해결의 실마리, 아이디어를 제공하는 중요한 인지로 논리와 함께 그 교육의 중요성이 강조되어왔다. Fischbein은 직관을 기원에 따라 일차적 직관과 이차적 직관으로 분류하고, 직관에 있어서 개인의 경험과 학교 교육의 역할에 대해 언급하고 있다. 이러한 선행 연구에서 직관이 사회적 영향을 받고 있다는 것을 알 수 있다. 본 연구는 직관의 사회적 성격을 표면적으로 드러낸 도덕 심리학자 Haidt의 사회적 직관주의 모델을 수학문제해결 측면에서 살펴보았다. 이를 통해 수학문제해결과 직관 교육에 있어서 다음과 같은 시사점을 얻을 수 있었다. 첫째, 수학문제해결에서도 직관의 사회적 특성을 확인할 수 있다. 둘째, 사회적 직관주의 모델을 변형하여 직관이 작용하는 수학문제해결과정을 모델화할 수 있었다. 셋째, 수학문제해결에서 직관이 중요하고, 직관에 관한 의미 있는 경험이 교육적으로 제공되어야 한다. 넷째, 직관의 강건함과 전체성 등으로 인한 오류를 줄이기 위해 직관을 확인하는 교육, 즉 메타인지를 강조한 직관 교육이 요구된다.

The purpose of this study is to elucidate the source of U anormaly formed in stream water of the drainage system around the Shinbo talc mine area based on the hydrochemical properties of water masses including surface water and groundwater. The hydrochemical properties of water masses in the Shinbo talc mine area are divide into three types; Type I : $Ca(Mg)SO_4$ type with high U content as shown in the stream water flowout from the mine, Type II : $Ca(HCO_3)_2$ type with high U content as in deep groundwater, Type III : $Ca(HCO_3)_2$, type with low U content as in the other stream water and shallow groundwater. It is necessary to emphasize that in deducing the uranium source, a distinct discrimination between type I and type II is showed in their hydrothermal properties in spite of commonly having a high uranium content, which in turn means the occurrence of a different water-rock interaction processes between both type. All evidences suggest that type II groundwater have acted as a primary media in the transport of uranium and that, as the groundwater flows through the talc mineralization zone, water composition of type II was transformed into that of type I water as the results of a secondary water rock interaction process, caused by imposition of new mineralogically controlled thermodynamic constraints. Consequently, in the viewpoint of hydrochemical exploration, the investigation of the hydrologic circulation system and the hydrogeologic properties for the aquifer of type II groundwater shall be done first of all and will provide a crucial clue on tracing the uranium mineralization zone occurred in the Shinbo talc mine area.

It has been recognized that the cityscate identity is a very important factor in a modern city. It is necessary to have a variable view to urban comunities for understanding the cityscape identity. We have investigated the contents of archaic texts such as the geography for tracing a cityscape identity to its origin in a city. Because it has been written about politics, economics and culture of a specific area in the geography based on deep interest to the city, we can look into the early image of the cityscape closely after searching of archaic texts. It is also significant to stdy with archaic texts of geography since these studies have a correlatio to the understand of an area and the keeping of historical conscious which are fundamental of cityscape identity. We have studieds on the area of Cheongju from the middle of Chosun dynasty to the end of this kingdom, since that many geographies were described those days. It was selected "Go-Reo-Sa" and "Se-Jong-Sil-Lok" Geography, "Sin-Jeung-Dong-Guk-Y대-Ji-Seung-Lam" "Dae-Dong-Ji-Ji" "Dong-Guk- Yeo-Ji-Ji", "Jeug-Bo-Mun-Heon-Bi-Go Yeo-Ji-Go", and "Taek-Li-Ji", as archaic texts of geography because these texts described in detail about city and gave a clue to speculate an image of city. The major results are as follows; 1) It was described about the cityscape in those archaic texts are metaphysical image, existing and usable elements of cityscape, lost resources of cityscape. 2) The metaphysical images are neither objective nor consistent in the each archaic texts. But the metaphysical image of old city suggests good insight for the application to the modern city image. 3) It is necessary to the careful onsideration about the existing elements. 4) There are variable programs about the lost resources of the cityscape, in accordance with the possibility of the restoraton. 5) The physical and visible factors and non-physical and invisible factors are equally important elements of the cityscape identity. Our research suggests that it is necessary to understand in detail how those factors of cityscape identity have changed with the changes of the times, and how those factors affect the modern cityscape identity.

The purpose of this study was to provide data to increase the success rate of penalty kicks through quantifying the shape of skilled kicks by performing a kinematic analysis on the change of movement during the kicking phase which the goalkeeper uses as a vital clue. Three high definition video cameras(GR-HD1KR, JVC, Japan) were used for the study and 18 reflective markers were attached to the body joints. Corners of the goal, difficult for goalkeepers to block, were set as aims and 1 m by 1.2 m targets were installed. Each subject had five sets of kicks at random, and the analysis was done on the movements that hit the target. Time, speed of the right lower limb's center of mass, joint angle, and angular velocity were chosen as factors and the results of the analysis showed statistical significance. The player taking a penalty kick should train to avoid leaning one's body towards the kicking direction and change the angle of the right foot right before the impact to decide the direction of the ball. The goalkeeper can increase the save success rate by studying the angle of the kicker's body and the right foot as well as the timing of the kick.

TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin) and related halogenated aromatic hydrocarbons elicit a diverse spectrum of biochemical and toxic responses in laboratory animals and mammalian cells in culture. Toxicity and carcinogenicity of TCDD is well established but the molecular mechanism is still poorly understood. Here, we found the noble responsive genes to TCDD using the differential display analysis. Treatment of HepG2 cells with TCDD showed a significantly different mRNA expression pattern from the untreated cells in differential display analysis. The differentially displayed bands were isolated and used as probes in dot blot and Northern blot analyses. Of thirty-five isolated differentially displayed bands, only two bands were confirmed as positive in dot blot and Northern blot analyses. The nucleotides sequences of these clones were analyzed and the search of Genebank database revealed that one clone is highly homologous with RanBP2 (Ras-related nuclear protein binding protein2; 92%) and the other is an unknown gene. RanBP2 is a nucleoporin with SUMO E3 ligase activity that functions in both nucleocytoplasmic transport and mitosis and its role as a novel tumor suppressor has been recently proposed. Thus, these results may suggest the clue elucidating the toxic mechanism of TCDD through RanBP2.

A 52-year-old woman with a history of general weakness, fatigue, weight loss, elevated serum levels of liver transaminase enzyme for three months underwent an F-18 FDG PET/CT scan to evaluate a cause of the hepatosplenomegaly found on abdominal ultrasonography. Initial PET/CT revealed markedly enlarged liver and spleen with intense FDG uptake. Otherwise, there were no areas of abnormal FDG uptake in whole body image. Histological evaluation by a hepatic needle biopsy demonstrated diffuse large B cell type lymphoma and final diagnosis for this patient was hepatosplenic B-cell lymphoma. She received five cycles of CHOP chemotherapy, and second PET/CT scan was followed after then. Follow-up PET-CT revealed normal sized liver with disappearance of abnormal FDG uptake. Hepatosplenic B-cell lymphoma is relatively rare and mostly presents as single or multiple nodules.1,2 Diffuse type hepatosplenic lymphoma is extremely rare and poorly recognized entity.3 The diagnosis is very difficult and complicated by the presence of misleading symptoms.4 In this rare hepatosplenic B-cell lymphoma case, F-18 FDG PET/CT scan provided a initial diagnostic clue of hepatosplenic lymphoma and an accurate chemotherapy response.
