21세기 지식기반사회는 자기 주도적으로 정보를 처리하고 해석하며 판단하는 능력과 지적 가치를 창조할 수 있는 능력을 길러주는 학교수학 교육을 요구하고 있다. 이에 수학교육과정에 담겨져야 할 수학적 지식의 구조․내용․범위, 지식기반 사회에 적합한 수학과 교수-학습, 평가, 교사역할 등 역시 새로운 관점에서 재조명될 필요가 있으며, 이러한 연구는 학교 현장에 대한 이해에서 출발하고 개인의 필요성과 사회의 요구를 반영한 것이어야 한다. 이에 본 연구에서는 지식기반사회에 대비하기 위한 수학과 교육과정 개발 연구의 기초 단계로 교사, 학생, 학부모를 대상으로 현장 설문 조사를 전국 규모로 실시하였다. 설문 조사는 Goodlad의 학교 교육과정 탐구의 개념적 구도를 바탕으로 한국 교육의 실정을 반영하여 설계되었다. 수학 교육과정 실체의 다양한 국면을 조사하기 위한 설문 내용은 목적 및 목표, 교과내용, 교수-학습방법, 평가, 수학적 지식의 성격, 교육정보화, 교사교육, 사교육, 교육과정일반으로 구성되었다. 본 고에서는 Goodlad의 교육과정 탐구모형과 그 모형에 기초하여 작성된 본 연구의 수학교육과정 탐구모형, 실시된 설문조사의 방법 및 절차를 소개하였고, 설문조사의 주된 결과를 토대로 수학교육과정 개발연구에의 시사점을 찾고자 하였다. This study is to provide suggestions for the development of better mathematics curriculum model of Korea based on a national survey of teachers (527), students (1314), and parents (638). It is our belief that understanding the perceptions and experiences of those involved in the process of teaching and learning of mathematics education needs to be the first priority in any effort to explore better mathematics curriculum model. For the study, Goodlad's conceptual system for curriculum inquiry has been used, but modified to take into account Korean context and the nature of mathematics curriculum. In this paper we introduce the Goodlad's curriculum inquiry model and mathematics curriculum inquiry model based on the Goodlad's conceptual system as well as the survey process. We made few recommendations from the main results of the survey for the research and development of mathematics curriculum model in Korea.

Trauma is one of the most common causes of death. Recently, injury severity score(ISS) is widely used to evaluate and classify the patients with multiple injury. Trauma score(TS) was developed as a means of providing rapid accurate assessment of the injured patient. Authors conducted a review of trauma patients who visited the emergency department of YongDong Severance Hospital from September 1992 to August 1993. ISS and TS were collected from comprehensive initial evaluation. The results were as follows : 1) The subjects were 10.2%(2,666 patients) of total 26,202 emergency patients. 2) Male to female ratio was 2.1 : 1. The age distribution was highest under 10 year(24.9%). The mean ISS was 3.5, and the mean ISS increased with ago. 3. Analysis of injury mechanism showed high incidence of traffic accident(35.3%), blunt trauma 25.7%, fall 24.2%, stabbing 10.7%, and others 4.3% in order. 4. The 8.0% of patients were admitted after initial management and their mean Iss was 12.6 mean TS was 15.5. 5. Among admitted traffic accident patients, the mean ISS of passenger T.A., pedestrian T.A. and driver T.A. were 19.0 ±9.9, 14.4 ±10.6, and 11.3 ±7.7 respectively. 6. Among 42 mortality cases, 25 patients were D.O.A. and 17 were expired. The mean ISS of D.O.A. Patients was 30.0; the mean Iss and mean Iss and mean TS of expired patients were 28.3 and 11.8 respectively. 7. The most common cause of death was head trauma(66.7%). 8. By comparing the ISS and TS of admitted and expired patients, mortality occurred above 16 point of ISS. The mortality increased with increasing ISS, but it was influenced by the trauma site and the severity of the particular injury site. Mortality also occurred below 15 point of TS, the mortality increased inversely with TS, and the mortality with TS, and the mortality was high below 13 point (above 40%).

Objectives: Thromboembolism is a serious medical problem causing considerable morbidity and mortality. Major clinical risk factors for thrombosis included surgery, fracture, malignancy, old age, immobilization and the use of oral contraceptives. In the last several decades, substantial progress has been made in identifying hereditary factors predisposing to thrombosis. The genetic defects known to be associated with thrombophilia are deficiencies of antithrombin 3, protein C, protein S, dysfibrinogenemia and resistance to the anticoagulant action of activated protein C. We have elucidated the characteristics of heriditary thrombophilia of the Korean patients. Methods: The clinical profiles of 48 patients with heriditary thrombophilia (12 cases of our hospital and 36 cases reported previously in Korea) were analyzed. The underlying hemostatic abnormalities about antithrombin 3, Protein C, Protein S, activated protein C, fibriongen were investigated. Family studies of 6 patients of our 12 patients were done. Nucleotide sequences of antithrombin 3 genes of 2 patients were studied. Results: 1) Seven patients (58%) among our 12 patients had thrombotic onset before fifth decades, and 5 patients developed thromboses at their third decades. 2) Pulmonary embolisms were diagnosed in 10 cases (83%) among our 12 cases. Deep vein thromboses of lower extremities were 8 cases (67%) and usually rare site thromboses like a portal vein thrombosis occurred frequently (8 cases, 67%). Arterial thromboses occurred in two cases (17%). Hereditability of 5 families were confirmed by family study. 3) Analysis of 48 cases showed that protein C deficiency (12 cases, 25%) and protein S deficiency (19 cases, 40%) occurred relatively frequently. 4) Neither Resistance to activated protein C nor mutation in the factor V gene was demonstrated in Korean patients with deep vein thrombosis and normal persons. This result suggests that activated protein C resistance may be extremely rare in Korean population. 5) Two new mutations of antithrombin 3 genes were identified in two patients via nucleotide sequencing, and they were named 'AT 3 Seoul' and 'AT 3 Kosung' respectively. Conclusion: We elucidated clinical and laboratory characteristics of hereditary thrombophilia in Korea. Hereditary thrombophilia were not uncommon in Korean patients with deep vein thrombosis, with/without pulmonary embolism. Strong suspicion for hereditary thrombophilia may lead to correct diagnosis and appropriate treatment in these patients.

This study aims to identify factors influencing people's recognition of space in virtual space of on-line games. Game users access a game and share its space to enjoy various contents. It can be said that virtual environment in games is different from the ones realized in other existing studies in that game users are exposed to virtual space for a relatively long period. Users can move by watching key maps. Through this study, we will learn to predict how users of virtual space act in that space when we are designing a virtual space, and also to understand which factors of space recognition influence users in their space recognition of virtual space. In addition, we will be able to learn what kind of influence key maps have on people's behaviors. The regression analysis results of the syntactic properties and the traffic volume show that global integration had the highest correlation, followed by depth, distance, and local integration. These results are contrary to results of existing studies, in which local integration is shown to have the highest correlation in real world.

This study was carried out over two consecutive years to evaluate the effects of polyethylene (PE) film liner, 1-methylcyclopropene (1-MCP), and aminoethoxyvinylglycine (AVG) treatments on fruit quality attributes of ‘Tonewase’ persimmon in cold storage. Fruit was harvested at two different levels of maturity, at a normal commercial harvest date in the first year and 10 days earlier in the second year. The PE film liner treatment significantly suppressed losses of fresh weight during cold storage, compared with the other treatments in both years. However, peel color variables (L*, a*, and b*) in the calyx-end regions declined when treated with the PE film liner, compared with the other treatments in both years. None of the treatments affected ethylene production and fruit decay was not detected during storage between the treatments. The highest level of fruit softening was observed in persimmon fruit treated with the PE film liner, while the softening rate in the other treatments was less than 50% at the end of cold storage. Fruits in all treatments were unmarketable after 2 months of storage. For the persimmon fruit harvested at the normal harvest date, the treatment with 1-MCP resulted in the highest average respiration rate and the lowest soluble solids content (SSC), compared with fruit in the other treatments. For the persimmon fruit harvested at the early harvest date, flesh firmness of fruit treated with the PE film liner declined significantly, but less so than for fruit in the other treatments by the end of storage, whereas the SSC and respiration rate were not affected by any of the treatments during cold storage. The PE film liner significantly reduced fresh weight loss during cold storage and flesh firmness and peel color were significantly affected by this treatment in second year. Overall, the results suggested that fruit harvest time in terms of fruit maturity and PE film liner treatment would retain greater fruit quality attributes during storage.

Cho, Jung-Hae,Nam, In-Chul,Park, Jun-Ook,Kim, Min-Sik,Sun, Dong-Il Mutaz B. Habal, MD 2012 JOURNAL OF CRANIOFACIAL SURGERY - Vol.23 No.4

BACKGROUND: The clinical and radiologic features of submandibular triangle hemangioma have not been systematically reported. Hemangiomas in the submandibular triangle are very rare and are often misdiagnosed as other benign cystic masses or inflammatory conditions. METHODS: We retrospectively reviewed the medical records of 5 patients who underwent surgery for submandibular triangle hemangioma between January 2006 and April 2011. RESULTS: All patients presented with fluctuating swelling with or without pain in the submandibular triangle. Computed tomographic (CT) scans showed cystic masses around the submandibular glands and calcified nodules in the lesions. Ill-defined vascular lesions and variably sized hard nodules were identified during surgery. Bleeding was controlled by early ligation of feeding vessels. The submandibular gland was removed for surgical exposure in 4 patients. Pathologic review of each specimen revealed that all were cavernous hemangiomas with thrombosis and phleboliths. Complications included 1 temporary marginal mandibular nerve paresis and 1 postoperative hematoma. No recurrence after surgery was seen during a follow-up period of 4 to 52 months. CONCLUSIONS: The possibility of submandibular triangle hemangioma should first be considered when a cystic mass around the submandibular gland and multiple calcifications are present on CT. Ligation of feeding vessels and resection of the submandibular gland may be needed to obtain surgical exposure and prevent massive bleeding.

Cryptococcosis is a common opportunistic infection in patients with acquired immunodeficiency syndrome and other causes of reduced immunity. Majority of pulmonary cryptococcosis patients exhibiting non specific clinical manifestations. So diagnosis of pulmonary cryptococcosis in patients without underlying diseases is generally difficult. Especially in an area with a high prevalence of pulmonary tuberculosis and when it shows cavitary lesion, pulmonary cryptococcosis is likely to be misdiagnosed as a pulmonary tuberculosis. We present here a case of pulmonary cryptococcosis that mimicked pulmonary tuberculosis in an immunocompetent patient. A 29 -year- old man presented with a 4 -day history of productive cough, low grade fever and left pleuritic chest pain. The serum anti-HIV antibody was negative. A chest X-ray showed patchy infiltration on the left upper lung field. Computed tomography (CT) showed segmental consolidation in the anterior segment of the left upper. The examination of the sputum for acid-fast bacilli with gram staining and culture did not reveal any organisms. Four days later the patient respiratory symptoms was aggravated. A follow-up chest CT demonstrated progression of the segmental consolidation with cavitation and necrosis. We conducted bronchoalveolar lavage and fluid culture was negative and there were neither acid-fast bacilli nor any pathogens. To get a tissue specimen, we conducted ultrasonography guided percutaneous needle aspiration. The specimen exhibited multiple areas of granulomatous inflammation and round, yeast-like bodies. Mucicarmine stain for the capsular material was incompletely positive and the Fontana-Masson silver stain was negative. The tissue fungal culture did not grow Cryptococcus. The result of the serum cryptococcal antigen test was positive, with a titer of 1:256. The result of the histology and the high titer of SCA strongly suggested pulmonary cryptoccosis, so we conducted polymerase chain reaction (PCR) for the tissue and the PCR from the tissue specimen was positive for cryptoccosis. Treatment with 400 mg/d of oral fluconazole for 9-month course was initiated. At the end of treatment, pulmonary lesions were improved on the follow-up CT.
