선물시장에서의 투자자 형태에 관한 이론적 연구

이상호,권순삼 경일대학교 산업정보연구소 2000 産經硏究 Vol.6 No.2

한국의 선물시장은 1996년 주가지수선물을 도입으로 지금은 CD선물, 금선물, 외환선물 등 선물의 종류도 점차 많아지고 있다. 미국의 경우 선물시장은 주식시장보다 더 활성화되어 있고, 그 밖의 선진국에서도 선물시장이 도입되어 활발히 운영되고 있는 현실을 보면 향후 한국의 선물시장도 점차 활성화되리라 본다. 이러한 시점에서 선물시장에 참여하는 투자자의 행태를 분석해 보는 것은 의미 있는 일이라 하겠다. 본 연구에서는 주식시장에서 투자자의 행태분석에 유용한 틀을 제공하고 있는 네 가지의 가설을 살펴보고, 한국의 주가지수선물시장에서는 어떤 유형의 투자자가 주가지수 선물가격에 영향을 미칠 수 있는지를 살펴보았다.

언어적 창의력 프로그램 개발 연구

이삼형,유영희,권순각 국어교육학회 2004 國語敎育學硏究 Vol.19 No.-

국어과 창의력은 언어적 창의력으로 구체화될 수 있으며, 언어적 창의력은 표현과 이해의 과정 전반에 걸쳐 두루 나타나고 있음을 알 수 있다. 언어적 창의력을 기르기 위해서는 일반적인(범교과적인) 창의적 프로그램에서 채택하고 있는 단순한 창의력 기법의 연습보다는 구체적인 과제를 해결해 나가는 실제적인 언어 활동을 통해서 하는 것이 바람직하다. 실제의 언어 활동에서 발현되는 창의력은 이해와 표현 모두 발상-구조화-언어화의 단계를 거쳐 결과가 나타난다. 창의력 프로그램은 발상, 구조화, 언어화, 메타화 등의 단계로 구성된다. 발상 단계에서는 느끼기와 깨닫기, 구조화 단계에서는 구체화하기, 관계짓기, 뒤집어보기, 미루어두기, 언어화 단계에서는 경험화하기, 감각화하기, 의미화하기, 개별화하기의 활동을 통해서, 메타화 단계에서는 선택하기, 배열하기, 평가하기 등의 활동을 통해서 학생들의 창의적인 능력을 신장시킬 수 있다. 본 연구의 활용 방안은 다음과 같다. 첫째, 언어적 창의력이 표현과 이해의 언어 활동과 별개로 존재하는 것이 아니므로 교과서의 학습 활동을 구체화하여 국어과 수업에서 창의적인 활동이 활발하게 이루어질 수 있도록 한다. 둘째, 발상 단계, 구조화 단계, 언어화 단계, 메타적 단계 등 각 단계에 적합한 활동들을 실제 수업에 활용할 수 있도록 구체화하고 나아가 학교장 재량활동 시간에 활용할 수 있도록 한다. The creativity which is essential ability in our own day is embodied by verbal creativity in Korean language education. The verbal creativity is realized in the all process of comprehension and expression. In this view it is more effective to develope verbal creativity through practical verbal activity than training creative technique. The creativity in the process of both comprehension and expression is similar. The creativity in the process of comprehension has to be embodied in text, it in the process of expression is based on new understanding about object. So that, the process of verbal creativity consists of the stage of idea that is starting point of new understanding, the stage of construction that organizes the new idea, the stage of language that embodies text. The program of verbal creativity consists of the stage of idea, construction. language and meta-cognition.

A 19-year-old man was referred to Seoul National University Dental Hospital for evaluation of a large painless swelling of the left mandibular angle area in August, 1999. The growth had been first noted 6 years ago. He had visited other hospital in 1997. In spite of the treatment given at the hospital, the mass continued to grow rapidly. Conventional radiographs in 1999 showed an expansile, lobulated, and destructive lesion of the left mandibular body. CT scan demonstrated an expansile mass with a corticated margin. Bony septa were seen within the lesion. Internal calcification noted on the bone-setting CT image, and corresponded to the hypointense area in T1-weighted MRI image. MRI clearly delineated the extent of the lesion which had heterogenous intermediate signal intensity in T1-weighted images and heterogenous hyperintense signal intensity in T2-weighted images. The lesion was well-enhanced. Histopathologically, the lesion was well demarcated. Multinucleated giant cells were presented in a fibrous background, demonstrating a storiform pattern. Areas of osteoid rimmed by a few osteoblasts were scattered throughout the lesion. Inflammatory cells, blood vessels, and hemosiderin deposition were also shown. CGCG may show lots of internal calcification foci on the CT, and varied signal intensity in MRI. More cases will be needed to understand the features of the CT & MR fonding of CGCG.

To investigate the level of depression and related ADL(activities of daily living scale) in elderly patients, 532 elderly were directly interviewed using questionnaires at 6 community health posts in Koje City, Kyungnam Province from July to August 2000. The functional capacity of daily living was assessed by 6-item ADL. Level of depression was measured by 15 item GDS_SF scales. The data on personal characteristic and history were also obtained. The prevalence of depression in men(74.3%) was significantly lower than that in women(84.4%) (p<0.05). Percentage of ADL dependent patient who were not able to perform one of more items was 8.6% in men and 8.0% in women. The prevalence of depression in ADL independent male patient was 71.8% while that in ADL dependent male patient was 100% (p<0.05). On the other hand, the prevalence of depression in ADL independent female patient was 82.9% while that in ADL dependent female patient was 100%(p<0.01). The level of depression and related ADL was significantly high in all elderly patients living in Koje City. Depression level was significantly different according to living expenses and self-rated health status in men, while it was different according to level of education, living expenses, self-rated health status, with or without spouse, nurse to help, with or without collocutor, smoking, medical history for the last 15 days and the last three months in women.

이영미,최항문,허민석,이삼선,최순철,박태원 대한구강악안면방사선학회 2000 Imaging Science in Dentistry Vol.30 No.3

Purpose : The study was aimed to detect the induction of apoptosis, cell cycle arrest and calcified nodule formation after irradiation on primarily cultured osteoblasts. Materials and Methods : Using rat calvarial osteoblasts, the effects of irradiation on apoptosis, cell cycle arrest, and calcified nodule formation were studied. The single irradiation of 10 and 20 Gy was done with 5.38 Gy/min dose rate using the 137Cs cell irradiator at 4th and 14th day of culture. Apoptosis induction and cell cycle arrest were assayed by the flowcytomtry at 1,2,3, and 4 days after irradiation. The formation of calcified nodules was observed by alizarin red staining at 1,3,10,14 days after irradiation at 4th day of culture, and at 1,4,5 days after irradiation at 14th day of culture. Results : Apoptosis was not induced by 10 or 20 Gy independent of irradiation and culture period. Irradiation did not induced Gl arrest in post-irradiated ostedblasts. After irradiation at 4th-day of culture, G2 arrest was induced but it was not statistically significant after irradiation at 14th-day of culture. In the case of irradiated cells at 4th day of culture, calcified nodules were not formed and at 14th-day of culture after irradiation, calcified nodule formation did not affected. Conclusion : Taken together, these results suggest that Irradiation at the dose of 10-20 Gy would not affect apoptosis induction of osteoblasts. Cell cycle and calcified nodule formation were influenced by the level of differentiation of osteblasts. (Korean J Oral Maxillofac Radiol 2000; 30: 189-198)

Purpose : The purpose of this study was to evaluate the morphologic features of posterior edentulous mandible for Korean patients using cross-sectional CT images. Materials and Methods : Computed tomographic cross-sectional views taken in 2004 and 2005 at Seoul National University Dental Hospital were analyzed by an oral and maxillofacial radiologist. Four indices were measured to meet the purpose of this study: 1) the horizontal distance between the alveolar crest and mandibular canal (Type), 2) the angle of the mandibular long axis (Angle), 3) the bucco-lingual location of mandibular canal, and 4) the depth of the submandibular fossa. The averages and standard deviations of the measurements were compared according to the location (the first and second molar area) and sex of the patients. Results : Statistically significant difference was found in Type, Angle, and submandibular fossa depth between the first and second molar area (P<0.05). However, there was no significant difference between men and women in any of the measured indices. Most of the mandibular canals were located in lingual side of posterior mandible. Conclusion : More care should be taken when an implant is installed on the mandibular second molar area.

Purpose : The purpose of this study was to develop a stent-based image guided surgery system and to apply it to oral and maxillofacial surgeries for anatomically complex sites. Materials and Methods : We devised a patient-specific stent for patient-to-image registration and navigation. Threedimensional positions of the reference probe and the tool probe were tracked by an optical camera system and the relative position of the handpiece drill tip to the reference probe was monitored continuously on the monitor of a PC. Using 8 landmarks for measuring accuracy, the spatial discrepancy between CT image coordinate and physical coordinate was calculated for testing the normality. Results : The accuracy over 8 anatomical landmarks showed an overall mean of 0.56±0.16 mm. The developed system was applied to a surgery for a vertical alveolar bone augmentation in right mandibular posterior area and possible interior alveolar nerve injury case of an impacted third molar. The developed system provided continuous monitoring of invisible anatomical structures during operation and 3D information for operation sites. The clinical challenge showed sufficient accuracy and availability of anatomically complex operation sites. Conclusion : The developed system showed sufficient accuracy and availability in oral and maxillofacial surgeries for anatomically complex sites. (Korean J Oral Maxillofac Radiol 2009; 39 : 149-56)
