김신곤 한국영유아보육학회 2007 한국영유아보육학 Vol.0 No.48

The purpose of this study is the analyze the scientific misconception in young children. Although young children are have the misconception about scientific events and this misconceptions are have an effect on the next science learning. To achieve the purpose, 150 children attending the nursery school in Gyeon-nam area were selected and the children participated in 18 items of the scientific questionnaire. According to the results of this study, young children have a misconception in each items that is constituted to observations on the present situations and superficial ideas on the science conceptions. Therefore, from the findings of this study, it is necessary that scientific education for conceptual change and developing appropriate training methods and teaching models. 본 연구는 유아가 지니고 있는 과학적 개념의 연령별 차이에 대한 양적 분석과, 유아의 과학적 오개념 반응을 범주화하여 이를 분석하는데 연구의 목적이 있다. 연구를 위해 10개소의 유아교육기관에 재원중인 만3, 4, 5세 유아 150명을 대상으로 과학개념을 검사하였으며, 연령에 따른 개념 형성의 변화추이와 오개념의 유형을 범주화하여 분석하였다. 각 문항에서 나타난 유아들의 응답에 대한 오개념 반응을 분석한 결과 각 문항에서 나타나는 유아들의 오개념 반응들은 밖으로 드러나는 현상을 관찰한 결과로 형성하였거나 피상적인 인과관계의 수준을 벗어나지 못하고 있는 것으로 나타났다. 따라서 유아에 대한 과학적 개념 변화를 위한 적극적인 교육이 필요하며, 이를 위한 과학적 개념변화 교수 모형의 개발이 요구된다고 하겠다.

김신곤,진동욱 국제e-비즈니스학회 2006 e-비즈니스 연구 Vol.7 No.4

Ubiquitous Computing System is wireless networking system that exchanges information regardless of human beings and materials from everywhere. RFID technology, together with u-sensor network technology at the file of Ubiquitous Computing that can be applicable in different industrial division is recognizing as a core technology of next generation. RFID is a kind of no-touch-type identification technology where microchip is stuck in material and that transmits and manages the information of material as well as surrounding environment through the wireless frequency. RFID technology is widely utilized in industry, especially information that utilized by RFID system is generated to real time sensor, that produces massive amount of data which is incomparable to the quantity of information that was capable in past applications. However, at present data processor like middleware like EPC code, which manages only a simple type of data and there is lack of massive data management. This study investigates conceptual utilization part of RFID and core technology like EPC composition elements of network structure of EPC global, presents RFID based middleware trends and application plans, and effective real time processing plan of continuously entering data stream. And presents important utilization value and afterward prospects of RFID. 유비쿼터스 컴퓨팅은 언제, 어디서나, 사람과 사물의 구분 없이 상호간의 정보를 공유할 수 있는 무선 네트워크 환경을 의미한다. 유비쿼터스 컴퓨팅의 대열에서 u-센서 네트워크 기술과 함께 전파식별(Radio Frequency IDentification; RFID)기술은 다양한 산업분야에 적용가능한 차세대 핵심기술로 인식되고 있다. RFID는 사물에 초소형 칩을 부착하여 사물 및 주변 환경정보를 무선주파수로 전송하고 처리하는 일종의 비접촉식 식별기술이다. RFID 기술은 주요 산업전반에 걸쳐 다양하게 활용될 것인데 특히, RFID 시스템에서 활용하는 정보가 실시간 센서 정보로까지 발전하게 되면, 기존 애플리케이션에서 감당하던 정보량과는 비교할 수 없을 만큼 방대한 데이터가 발생하게 될 것이다. 그러나 현재 데이터처리를 담당하는 미들웨어는 주로 EPC 코드 등과 같은 간단한 형식의 데이터를 처리할 뿐, 대량의 데이터 처리에 대한 고려가 부족한 상태이다. 본 연구에서는 RFID에 대한 개념적 활용 분야와 핵심기술인 EPC global의 EPC 네트워크 구조의 구성요소를 알아보고, RFID 기반 미들웨어 동향 및 적용방안과 연속적으로 들어오는 데이터 스트림의 효과적인 실시간 처리방안을 기술하고, 주요 활용가치와 향후전망에 대해 제시하였다.

In 1968, Dudrick et al described a quite new method whereby severly ill patients could receive their total nutritional requirements intravenously via subdavian vein for periods of weeks or months. Parenteral hyperalimentaition has proved to be of immense value in a host of clinical situations, as there has been a growing awareness of the need for nutritional support in patients undergoing surgery, both postoperative morbidity and mortality rates have decresed with the use of total parenteral nutrition. This study analysed the clinical course of 80 patients receiving parenteral hyperalimentation for periods of 7 days or more at the Chonnam University Hospital form 1983 to june 1990. The results were as follows: 1) The age distributions in 80 patients are relativiely even between 3rd and 7th decade and sex distributions are male predominance with 53 cases of men than 27 cases of female. 2) Routes for central vein are mainly via subclavian vein (53.8%) and others were jugular or basilic vein. 3) Enterocutaneous filstula is the most common indication for hyperalimentation and others are pancreatitis, prolonged ileus, sepais, inflammatory bowel disease, acute renal failure, hepatic disease and so on. 4) Mean duration of hyperalimentation is 23 days and the longest period is 162 days in traumatic pancreatitis. 5) Complications of hyperalimentation are decreased hepatic function most commonly, infection, catheter sepsis and Zinc deficiency and that associated with technique are pneumothorax, arterial puncture, subcutaneous hematoma, intrapleural infusion and catheter embolism.

The management of compartment hypertension appears to be a valuable adjunctive procedure to improve the limb survival in various situations. In acute arterial occlusive diseases or arterial injuries when initial treatments are delayed, fasciotomy is indicated in addition to restoration of the blood flow. The authors evaluated clinically nine cases of the fasciotomy which were performed after arterial surgery for five years since 1985. The most common underlying disease was atherosclerosis and delay in diagnosis and treatment of acute arterial occlusion was the commonest indication. Limb amputaion was done in two cases and mortality in three cases. Delay in management less than 24 hours had a high limb salvage rate. High index of suspicion and early diagnosis and appropriate fasciotomy may increase limb salvage in acute arterial ischemic diseases.

Background: Metabolic syndrome (MS) is characterized by insulin resistance accompanied by one or more of the following: obesity, hypertension, impaired glucose tolerance, low HDL cholesterol levels, and/or hypertriglyceridemia. However, the precise underlying pathogenic mechanism of MS is not known. Several recent reports have suggested a positive association between components of MS and markers of the acute-phase response, including C-reactive protein (CRP). These results imply that MS is accompanied by an ongoing inflammatory process. The purpose of our study was to evaluate the association between circulating levels of C-reactive protein, a sensitive systemic marker of inflammation, with components of metabolic syndrome in Korean adults. Methods: A total of 1,461 subjects aged between 20 and 81 years, who visited the Health Management Center at Korea university between November 2000 and February 2001 were studied. We investigated the correlation between CRP levels and components of MS. The components of MS were categorized, and age-sex adjusted mean values of CRP calculated for the categorized components. The BMI was categorized into 5 classes, and the CRP levels examined according to their BMI class. In addition, subjects with a different number of the MS components were grouped as follows: group 1 for 0 components, group 2 for 1 components, group 3 for 2 components and group 4 for ≥ 3 components, and the CRP levels calculated for each group. Results: There were significant positive correlations of CRP levels with age, BMI, TG, systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBS), uric acid, insulin, and homeostasis model assessment IR (HOMAIR). A significant inverse correlation was observed between CRP levels and serum HDL. From the multivariate analysis, age and BMI were significantly correlated with CRP levels. The means of the CRP for the categorized components of MS were significantly higher in the BMI categories: ≥25 for female/27 for male, TG ≥200 ㎎/dL, fasting plasma glucose ≥126 ㎎/dL and blood pressure ≥140/90 ㎜Hg, and the CRP levels by BMI class were: 1.19 (BMI <18.5), 1.54 (BMI 18.5∼22.9), 1.59 (BMI 23.0∼24.9), 1.77 (BMI 25. 0∼29.9) and 2.07 (BMI >30.0) ㎎/L. Furthermore, the increase in the CRP levels in relation to the numbers of MS were 1.46 (group 1), 1.70 (group 2), 1.95 (group 3) and 2.11 mg/L (group 4) with statistical significance. Conclusion: The above data showed associations between the CRP levels and the different components of MS. This might suggest that MS in Koreans could be accompanied by a systemic inflammation response
