1. Purpose of the study As for the development of proportionality concept. Inhelder & Piaget(1995)mainly administered adjustment tasks and proposed domain generality.On the other hand siegler(1981) and other researchers made use of comparison task and proposed domain specificity. It is thought that the differencess of view points were caused by two types of tasks. This study used both of them and examined domain specificity among children's solutions to three domains;ve-locity, thickness and density. The purpose of the study was to examine the domain specificity of proportional concept clearly though there had been different view points among researchers. The hypothesis were as it followed. 1)The differences of task scores will be showed in comparison task not in adjustment task. 2)Because the adjustment task is more simple than the comparison task, the scores of adjustment task will be higher than those of comparison task. 3)The scores of speed will be the highest of three domains. 2.Method of the study The subjects of the study were administered to 152 pupils from 4th grade in elementary school to 1st grade in the middle school in Chulwon.Tasks were composed of both adustment thask and comparison task.For each task,it had velocity,thickness and density.Task scores,stages identified by reaction patterns and solution strategies were analyzed. 3.Comclusion of the study The results of study could be summerized as it followed. 1)For each grade task scores in adustment task didn't have meaningful significiences but in comparison task had meaningful significances. 2)Reasoning in adjustment task (Proportional reasoning)was mapped to the results of Piaget et al.. On the contrary the reasoning in comparison task(intensive quantity)was mapped to the results of Siegler et al.. 3)Because domain general sub process(relation representation) was more simple than domain specificity sub process(comparison process)the scores of adjustment task were higher than those of comparison task.

Background:Although Alzheimer's disease (AD) is a progressive neurodegenerative disorder without any truly effective pharmacological treatment at present, early accurate diagnosis is important for the delaying of disease progression and proper management It would be desirable to have a peripheral biological marker to identify patients affected by AD Amyloid β-peptide originates from a larger precursor, the amyloid precursor protein (APP). which can be seen in the platelet of its equivalent to those found in brain. To investigate if there is a correlation between level of platelet APP isoform and AD, we evaluate a cohort of subjects including patients affected by sporadic AD, vascular dementia, and controls Subjects & Methods :Thirty-five patients with sporadic AD diagnosed according to the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Relatec Disorders criteria (NINCDS-ADRDA) and 26 vascular dementia patients diagnosed by the Diagnosis and Statistical Manual of Mental Disorders, Fouth Edition (DSM-Ⅳ) criteria and 12 controls were included Blood sample were drawn from fasting state and collected into 3 mL of 3.8% sodium citrate. Platelets were collected by centrifugation at 500 g for 20 minutes and washed. and the platelet pellet was stored at -80℃ until used APP was assessed by western blot analysis and quantified by densitometry using Image Analyzer Results:In platelets densitometer as well as the result of Western blot was higher compared with those of patients with non-Alzheimer dementia and controls We observed statistically significant reductions in the ratio of 120 kDa to 130 kDa APP to 110 kDa APP (APPr) for patients with probable AD compared with control subjects and patients with vascular dementia APPr levels in AD correlated with the severity of dementia measured by CDR. Accuracy levels measured by Receiver Operating Curve analysis showed that a cut-off level of 0.45 resulted in a sensitivity of 71% and a specificity of 74%, with an area under the curve of 0 793 Conclusion:Platelet APPr allowed to differentiate AD from normal aging and vascular dementia with high sensitivity and specificity These findings suggest that platelet APPr may be a helpful peripheral marker for diagnosis and clinical progression of Alzheimer disease.

중증과 경증 여성장애인의 경제활동 참여 영향요인 연구

한애경,윤혜미 한국장애인고용공단 고용개발원 2012 장애와 고용 Vol.22 No.3

본 연구의 목적은 장애정도에 차이가 있는(중증과 경증) 여성장애인의 경제활동 참여 영향요인을 살펴보고 경제활동 참여를 활성화하기 위한 방안을 논의하고자 하는 것이다. 이를 위해 ‘2008~2010년 장애인고용 패널조사’에 3년간 참여한 여성장애인 1,714명의 원자료를 활용하여 로지스틱 회귀분석을 하였다. 연구결과 중증 여성장애인은 기초생활 수급자 일 때, 차별경험이 많을 때, 연령이 높을 때 경제활동에 참여할 승산이 감소한 반 면 고용서비스를 받은 경험은 경제활동 참여 증가에 기여하였다. 한편, 경증 여성장애인 이 경제활동에 참여할 승산은 기초생활수급자 일 때, 차별경험이 많을 때, 연령이 높을 때, 7세 미만의 자녀가 있는 경우 감소하였으나 자격증이 있는 경우 증가하는 것으로 나 타났다. 결론적으로 경제활동 참여 영향요인이 두 집단 간 서로 차이가 있었고 일부 유사 한 요인은 영향력의 크기에서 차이가 있음을 확인하였다. 이러한 결과를 토대로 여성장 애인의 경제활동 참여를 활성화하기 위한 방안을 중증과 경증 여성장애인으로 차별화하 여 제안하였다. Though employment has been proved to be one of the most effective approach toward social integration of women with disabilities, the double barrier of being a woman and being the disabled made it difficult for them to attract employers in the job market. This study focused on distinguishing the influencing factors of employment of women with differing degree of disabilities. Data of 1,714 disabled women from the 2008-2010 Panel Data of Employment of Persons with Disability were analyzed with logistic regression analysis. Research results showed that, overall, poverty(welfare recipient status), experience of discrimination, and old age made employment of disabled women more difficult. Women with severe disability who utilized governmental employment services had better chance being employed. Care burden of children under seven-years old proved to be the hindering factor for employment of women with less severe disability while licenses of specific skills help them to find jobs. Based on the findings, differentiated approaches to increase disabled women’s participation to the workforce based on the degree of disability were discussed.

하영애,정경동,천병렬 大韓産業醫學會 2000 대한직업환경의학회지 Vol.12 No.1

목적 : 근로자의 간기능 검사 이상소견 발생률과 그 관련요인을 알아보고자 일개 화학제품 제조 사업장의 근로자 579명을 대상으로 1997년 10월과 1998년 10월, 2회에 걸쳐 혈액검사 및 설문조사를 실시하였다. 방법 : 간기능 검사 3항목(AST, ALT, γ-GTP)에 대한 2회의 검사에서 모두 이상을 보이는 경우를 간기능 검사 이상소견자로 정의하였다. 일반적 특성(연령, 결혼상태, 학력), 근무부서, 유기용제취급여부, 생활습관(음주, 흡연, 운동, 식이습관), 간질환과거력, 간질환가족력, 약물복용력, B형간염표면항원양성률, 혈당치, 총콜레스테롤치 등을 독립 변수로 처리하였다. 1년 후 간기능 검사 이상소견 발생여부를 종속변수로 사용하였다. 1년 후 추적이 완료된 근로자수는 533명 (92.1%)이었다. 결과 : 간기능 검사 이상소견 연간 조발생률은 100명당 9.6이었고. 연령 표준화 발생률은 9.5이었다. 발생률에 유의하게 관련된 변수는 체질량지수, 음주량, 간질환과거력, 육류섭취였다. (p〈0.05). 다중로지스틱 회귀분석에서는 체질량지수(미교위험도 2.70: 95 % 신뢰구간 1.41∼5.16)와 음주량(비교위험도 1.98: 95% 신뢰구간 1.08∼3.60)이 유의한 변수였다. 체질량지수와 음주량의 변화를 고려한 층화분석결과, 체질량지수가 정상-정상이고 음주량이 소량-소량인 군에 비해 체질량지수가 정상-정상이고 음주량이 과량-과량인 군의 비교위험도가 2.24(95%신뢰구간 1.09∼4.62), 체질량지수가 비만-비만이면서 음주량이 과량-과량인 군의 비교위험도가 5.66(95%신뢰구간 2.69∼11.88)이었다. 결론 : 간기능 검사 이상소견 연간 연령표준화 발생률은 100명 당 9.5이었다. 발생률을 효과적으로 감소시키기 위해서는 체질량지수를 정상으로 유지하고 음주량을 줄이기 위한 적극적인 노력이 필요할 것이다. Objectives : This study was conducted to estimate the incidence of abnormal liver function and risk factors in male employees of an industry in Ulsan City. Methods : Five hundreds and seventy nine male employees were selected as the study cohort and 533 (92.1%) of them were followed after one year. The blood sample was collected to test for AST, ALT, γ-GTP, total-cholesterol, fasting blood sugar and a self-admlnistered questionnaire on life style was done. General characteristics (age, marital status, educational level) , job department, exposure status for organic solvents, life style (alcohol, smoking, exercise, diet) , past history of liver disease, family history of liver disease, drug Intake, HBsAg, blood glucose, total-cholesterol were considered as risk factors. The result of liver function test after 1 year follow-up was treated as dependent variable. The operational definition of abnormal liver function was as follows; those who had abnormal liver functions in the two repealed tests with one month interval. Results : The annual incidence of abnormal liver function was 9.6 per 100 and age-standardized incidence was 9.5. BMI, alcohol, past history of liver disease, and meat intake were significantly related to the incidence (p(0.05) . In multiple logistic regression analysis, BMI (RR=2.70, 95% Cl=1,41-5.16) and alcohol (RR=1.98, 95% Cl=1.08-3.60) were proved as the significant variables. By stratified analysis considering changing pattern of alcohol and BMI, the relative risk of the 'BMI normal-normal and alcohol intake high-high' group was 2.24(95% Cl=7,09-4.62) and that of the 'BMI obese-obese and alcohol intake high-high' group was 5.66 (95% Cl=2.69-11.88) compared with that of 'BMI normal-normal and alcohol intake low-low' group. Conclusions : The age-standardized annual incidence of abnormal liver function was9.5 per 100 in male employees. Thus, an active effort for reducing alcohol intake and controlling BMI should be done to reduce the incidence.

國民學校 低學年의 記數法 指導에 對하여

姜慶愛 대구교육대학교 1965 論文集 Vol.1 No.-

This is an experimental work to understand decimal notation. It was discovered that the majority of error types of accounting was due to not knowing number placement according to my first investigation on 600 children from the second grade to the fifth grade. My second investigation to let 896 children in three primary schools write numbers from 11 to 20 showed that 54 percent of error types also resulted from the negligence of decimal notation or number placement. Stimulated with these results the third research was made in cooperation with above school teachers to separate tens' place from ones' place with a teaching implement shown in §5 and to teach decimal notation, emphasizing number placement. The class with this teaching method had a good result, that is, the error made was from 56 percent at the second examination to 61 percent at the third whereas other classes without any experimental direction resulted from 47 percent at the second examination to 70 percent at the third in average. When 5 percent level of significance is used this teaching method has been proved its excellence.

1.Purpose of the study The purpose of this study is to test the validity of the assumption of developmental synchrony. Specially, investigations are made the extent to which performance and reasoning levels match each other among contexts, structure, item levels, presentation modes and grades. Item levels are determined by item characteristics developed by Noelting (1980 a), which distinguish a hierarchy of seven levels. Three items are involved for every level. Three contexts in this study are the marble task, the orange juice task and the balance beam task. These three contexts have similar structure of the two dimensions which are called 'dominant dimension' and 'subordinate dimension'. The representation modes are both picture method and symbolic method. The hypotheses are as it follows. 1) Both the marble task and the orange juice task are verified the validity of developmental synchrony in performance and reasoning levels of the subjects. 2) Both the balance beam task ad the order two tasks are verified the validity of developmental insynchrony in performance and reasoning levels of the subjects. 3) In solveing these proportional tasks with quantity stratrgies they will be able to sove them with consolidation. 4) Two modes of representation will influence upon the levels of performance and reasoning of the subjects. 2.Method of the study The subjects of the study are administered to 271 students from 1st grade to 3rd grade of the middle schools in Kyeongki and Kangwon province. They answer 21 items and their answer sheets are scored. Acording to their answer sheets their levels of performance and reasoning are determined. 3.Conclusion of the study 1) In both the marble task and the orange juice task developmental synchrony has meaningful significance. so the hypothesis is verified positive. 2) In both the balance beam task and the other two tasks developmental synchrony doesn't have meaningful significance. so the hypothesis is verified positive. 3) The third hypothesis is verfied negative. Though both the marble task and the orange juice task is used the same stratrgy and the developmental synchrony is taken place these datum are not verified clearly. 4) The fourth hypothesis is verified negative. The pictorial modes don't describe the characteristics of three tasks. In sum we say that the developmental synchrony isn't taken place in this study. So the developmental synchrony in tasks will be accomplished since high school student.

Ventricular septal defect remains an infrequent but devastating complication of acute MI. Approximately 1∼3% of cases of acute myocardial infarction are complicated by ventricular septal rupture in the prethrombolytic era and the incidence has decreased to 0.2% with reperfusion therapy. This mechanical complication usually occurs within the first 10 to 14 days when necrotic tissue is most abundant and the collateral coronary circulation is not well developed. This lesion is generally associated with complete coronary obstruction rather than severe stenosis. Rupture of the ventricular septum is a severe mechanical complication of acute myocardial infarction, usually resulting in death unless surgical repair is performed. The bad prognosis of this event within the first 2 weeks indicates the need for early surgical rapair. This complication is more frequent after the first acute myocardial infarction in the elderly and secondary to a transmural myocardial infarction. We report two cases of ventricular septal rupture after acute myocardial infarction.
