The purpose of this study is to evaluate the appropriate diagnostic methods for the patients with suspected intussusception. Intrssusception is a state that a portion of alimentary tract is telescoped into a segment just caudad to it, and has a characteristic symptoms of cyclic irritability, vomiting, bloody stools and palpable mass, It is the most common cause of acute or acquired intestinal obstruction in infants and children, and needs early diagnosis and immediate treatment. Authors reviewed retrospectively medical records of 411 infants & children with suspected intussusception from January 1, 1992 to December 31, 1994 and report the results with literature reviews. The results were as followings; 1) 263 cases were definite intussusception(DI) out of 411 suspected intussusception(SI). 2) The male to female ratio was 2.3 : 1 in SI and 2.8 : 1 in DI. 3) The distribution of age revealed that 85% of SI and 84% of DI were under 24 months old, and the most common age was 8 months in SI and 10 months in DI. 4) There were upper respiratory infection in 84 cases(2)%), gastroenteritis in 32 cases(8%) and bronchiolitis in 8 cases(2%) as preceding diseases. 5) The simple X-ray showed gaseous bowel distension in 212 cases(52%). 6) The most common symptoms and signs were cyclic irritability and abdominal pain(94%), bloody stools(72%), palpable abdominal mass(47%), in order. 7) Of 411 patients, 252 cases(61%) were diagnosed and treated by air enema(228 cases) and/or exploration(24 cases). Among 296 cases(72%) who showed bloody stools in digital rectal examination and glycerin enema, 245 cases(83%) were confirmed as intussusception through air enema and/or operative intervention, and that corresponds to 93% of DI. 8) Intestinal perforation as complication occurred in 3 of 393 cases who underwent air and barium enema, but all of them recovered without any sequelae after operation. Conclusively, it is thought that air enema preceded by digital rectal examination and glycerin enema is safe and useful method in diagnosis and treatment of infants and children with SI.

The purpose of this study is to clarify the effect of the monomer ratio on properties of the polymer-modified mortars using methyl methacrylate-ethyl acrylate latexes, and to obtain basic data necessary to develop appropriate latexes for cement modifiers. This paper deals with the effect of the monomer ratio on the typical properties of polymer-modified mortars with methyl methacrylate-ethyl acrylate latexes. The polymer-modified mortars using MMA/EA latexes are prepared with various polymer-cement ratio, and tested for strengths, water absorption, and chloride-ion penetration depth. The test results indicate that the monomer ratio is very important factors to characterize the strength properties of polymer-modified mortars, but the water absorption and chloride-ion penetration depth are influenced by polymer-cement ratio rather than monomer ratios.

It has been known that sternal fracture increases the risk of potentially life-threatening injuries, such as myocardial, pulmonary, and thoracic vascular injuries, and it has 25% to 45% of mortality, primarily resulting from these underlying injuries. The authors reviewed retrospectively the medical records and radiographic findings of the patients who admitted with sternal fracture at Chung Ang Gil Hospital from 1 June 1994 to 31 December 1995 to evaluate the significance and clinical course of sternal fracture. The results were followings: 1. The male to female ratio was 3:2 and the mean age was 43.1 and 45.4 years old in male and female, respectively. 2. Motor vehicle occupant accident was the most common cause of sternal fracture. 3. Of 33 cases, there was no death, but common associated injuries which were rib fracture, hemothorax, lung contusion, vertebral fracture, penumothorax, long bone fracture, myocardial contusion, flail chest, facial chest, facial bone fracture, and pericardial effusion, in order. 4. The clinical course of sternal fracture was determined primarily by associated injuries except for communited sternal fracture. 5. The patients with isolated sternal fracture, who had an otherwise normal chest x-ray, normal electrocardiogram, no other significant associated injuries and are hemodynamically stable, had a benign clinical course.

형남원 ( Nam Won Hyung ),전형철 ( Hyun Chol Jeon ) 명지대학교 금융지식연구소 2010 금융지식연구 Vol.8 No.3

국내의 일부 은행은 매일 오전 외환시장의 동향에 대한 정보를 제공하면서 환율의 금일변동의 예상범위를 제시하고 있다. 본고에서는 그 중 한 일반은행을 택하여 금일예상범위에서 제시된 일별 원/달러 환율의 예측치의 예측력을 분석하고, 시계열모형을 통한 예측력의 개선방안에 대해 연구하였다. 이 은행에서 제시하는 환율예측치를 벤치마크로 삼아 ARMA모형, GARCH모형, 지수평활화, 임의보행모형 등의 시계열모형의 예측치와 비교·분석하였다. 리먼 브라더스의 파산으로 촉발된 2008년 하반기의 국제금융의 위기로 인한 환율의 급격한 변동을 반영한 분석도 시도하였다. 예측의 편의성(biasness)을 검정하기 위한 MFE 통계량, 예측력의 우월성을 비교하는 RMSFE 통계량, 예측력의 통계적 차이를 검정하기위해 Diebold and Mariano 검정방법, 환율변동 방향에 대한 예측력을 검정하기 위해 DOC기준을 각각 사용하였다. 분석 결과 이 은행의 예측치가 다른 시계열 예측치보다 우수한 예측력을 가지는 것으로 나타났다. 국제금융위기로 변동성이 심해진 기간을 감안한 분석의 결과도 비슷하게 나타났다. 이 은행의 예측치와 시계열 모형 예측치를 반영하는 결합예측치를 만드는 경우 은행의 예측치가 가지는 편의성이 대폭 개선되는 것으로 나타났다. 그리고 예측력도 제한적인 범위에서 개선이 있는 경우도 나타났다. 특히 변동방향의 예측에서 상당한 정도의 개선이 있는 것으로 나타났다. This study investigates the performance of a major commercial bank in Korea in terms of forecasting daily exchange rates. The paper suggests several alternative forecasting methods based on time series models, including ARMA, GARCH, GARCH with a structural break, exponential smoothing, the random walk model. The out-of-sample forecasting performance of the bank`s forecasting method was compared with that of the alternative forecasting methods by using the root mean squared forecast error (RMSFE) and the direction of change (DOC). The results indicate that the bank`s forecasting method has a clear advantage over the alternative methods. However, the bank`s forecasting method offers no advantage in terms of the mean forecast error (MFE). The forecasting methods were then combined to improve forecasting performance. The results do not provide evidence of such an improvement in terms of the MSFE but indicate a significant reduction in forecast bias and an increase in forecasting performance in terms of the DOC.

이 연구는 여가스포츠 참여자의 여가행태 및 여가정체성이 가족기능에 미치는 영향을 파악함으로써 가족공동체 안에서의 진지한 여가가 갖는 의미를 해석 하는데 목적이 있다. 이와 같은 목적을 달성하기 위하여 여가스포츠참여자 320명을 대상으로 ‘여가정체성’과 ‘가족기능’척도를 이용한 설문지를 배포하였고, 최종분석에 사용된 설문지는 총 295부 이며 자료 분석을 위한 방법으로 차이검증과 회귀분석을 실시하였다. 본 연구 결과를 통해서 여가스포츠 참여자의 여가행태가 여가정체성에 미치는 영향이 규명되었고, 그들의 여가행태와 여가정체성은 가족기능에 부분적으로 부정적인 영향을 미침이 확인되었다. 이는 여가행태의 특정한 경향을 보이는 개인에게 있어서는 지금까지 선행연구들이 밝힌 가족기능에 긍정적 영향을 미치는 여가활동 요인이외에도 부정적인 영향을 미치는 요인들이 있음을 증명하며, 가족여가활동의 개선안이 필요함을 제시하는 근거로 활용 할 수 있다 The purpose of this study was to interpret and understand the meaning of serious leisure within family by examining effects of leisure style and leisure identity on family function. In order to achieve this research purpose, questionnaires using scales of 'leisure identity' and 'family function' were administered to 320 participants in leisure sports and total 295 papers of them were used for the final analysis. The primary data analyses used in this study were t-test and regression analysis. Through the results, effects of leisure style of participants in serious leisure were examined and it was identified that leisure style and leisure identity of participants had negative effects on family function. These results demonstrate that there are another factors having negative effects on family function, except for factors of leisure activity having positive effects on it, which previous studies have verified and the study results are able to be used as sources to suggest that improvements of family leisure activity.

지식 기반 사회는 새로운 지식과 가치를 창출하고 더불어 살 줄 아는 능력을 가진, ‘창의·인성적’ 인재를 원한다. 이에 2009 개정 교육과정은 창의․인성적 인재가 갖추어야 할 10가지 핵심역량을 제시하였고, 그 중 체육과 교육과정은 ‘문제해결능력’과 ‘자기관리능력’을 달성시키기에 적합한 교과로 분석되었다. 그러나 이것은 어디까지나 분석에 의한 결과일 뿐, 학교체육현장에서의 창의·인성 교육은 요원한 과제로 지적되고 있다. 따라서 본 연구에서는 체육과에서 지향하는 핵심가치들을 단순히 이해하는 것에서 나아가, 이러한 가치를 종합하고 창의적으로 조합할 수 있는 활용중심 교육으로 전환하기위하여 ‘창의·인성적 체육과 여가교육모형’을 개발하고자 하였다. 이를 위해 2009 개정교육과정(총론) 및 체육과 교육과정의 틀을 기준으로 여가교육 관련 문헌자료를 고찰했고, 전문가 협의과정을 거쳤다. 그 결과, 여가수용능력과 여가활용능력을 중심으로 학군별, 범교과 영역별로 여가교육 프로그램 세부내용을 개발하였다. 이는 학교체육현장에서 적용 가능한 구체적인 수업모형으로써 공교육의 창의·인성적 체육교육실현에 기여할 것이다. People want a ‘creativity and character' talented person who can create new knowledge and value, with the ability to know how to live with. 10 core competencies was proposed in 2009 revised school curriculum, physical education(P.E.) curriculum was classified suitable for 'problem solving skills' and 'self-management skills’. However, it is only for analysis, 'creativity and character' education has been pointed out to the distant challenge in school field. Therefore, the purpose of this study is to develop a leisure education model in P.E. for the creativity and character education not only for the simply understand the core value in P.E., but also, change over to the practical-use-centered education which can be combined these values creatively. For this purpose, literature(related to leisure education) review was conducted around 2009 revised curriculum and framework of the P.E. curriculum, also a process of experts consultation was done. As a result, leisure education in P.E. level was divided into 3 steps, ‘leisure acceptance ability’, ‘leisure application ability’, ‘continuous leisure education’. Also leisure education program was developed classified by school district, focusing on ‘leisure acceptance ability’, ‘leisure application ability’
