Background: We have doubt about the truth that Type 2 DM is associated with chronic hepatitis C infection. The aim of our study was to prove a close relationship between chronic HCV infection and type 2 DM in korean patients. Methods: We reviewed the out-patient's medical records of 466 patients with type 2 DM who visit the Sung-ae hospital from March 2000 to August 2001. Diabetic patients were analyzed for the following variables: age, sex, waist circumference, weight, waist/hip ratio, using of self monitoring of blood glucose, method of therapy, duration of disease, experience of previous transfusion, major surgical procedure, accompanied disease, liver function tests (LFT), HbA1 c. We ruled out patients with liver cirrhosis. Results: Hepatitis C virus infection was observed more frequently in patient with Type 2 DM. Of 466 Type 2 DM patients, 13 patients were infected with Hepatitis C virus (2.79%). Compared with mean prevalence of Korean population (1.3~1.6%), it's value is very high. the other hand, 21 patients were infected with Hepatitis B virus (4.5%). Such results are similar to mean prevalence of the general public (4~5%). Conclusions: Prevalence of hepatitis C was closely associated in korean patients with type 2 DM. And an increased prevalence is independent of cirrhosis.

본 연구는 노랫말 바꾸기 활동이 유아의 어휘력과 창의성에 미치는 영향을 알아본 것이다. 본 연구대상은 만 5세 유아 40명이었고, 16주에 걸쳐서 통제집단은 일반적인 노래부르기 활동을, 실험집단은 노랫말 바꾸기 활동을 실시하였다. 검사도구는 김영태 등(1995)의 그림어휘력 검사와 전경원(2000)의 창의성 검사를 사용하였다. 검사결과, 1) 노랫말 바꾸기 활동은 유아의 어휘력 발달을 유의하게 증진시켰다. 2) 노랫말 바꾸기 활동은 유아의 창의성 발달에도 효과가 있었는 데, 상상력과 신체영역을 제외하고는 모든 척도별 창의성(유창성, 융통성, 독창성)과 영역별 창의성(언어, 도형)을 유의하게 증진시켰다. 따라서 노랫말 바꾸기 활동은 유아의 어휘력과 창의성 발달에 효과적인 활동임을 알 수 있다. This study investigated the effects of changing the verse of the song on young children's vocabulary and creativity. The activities were designed by researchers and constructed by 4 steps such as 1) learning a new song, 2) changing the words, 3) creating a song book, and 4) presentation. The subjects of this study were forty five-year old children from two classes at G kindergarten in K City. Twenty children were in the experimental group and twenty children were in the control group. The method of changing the verse of the song was used over a 16 week period. The vocabulary test(Kim Young Tae et al, 1995) and The creativity test(Jeon Gyeong-Weon, 2000) were administered and analyzed by t - test with SPSS/pc programs. The results were as follows: 1) Changing the verse of the song contributed to increasing young children's vocabulary significantly. 2) Changing the verse of the song contributed to increasing young children's creativity significantly. And the significant effects appeared in sub-scales of fluency, flexibility, and originality except imagination and in sub-areas of language and figure.

This study investigated the effects of the householder's age as a proxy for the family life cycle stage variable and the householder's occupation on the household financial structures. Household financial structures are analyzed by the components of two financial statements(the incom and expense statement and the balance sheet statement) and selected financial ratios. The data came from the 1998 Korean Household Panel Study. It wah found that the age profiles of household finances such as household income, expenditure, savings and consumption rate, financial assets, real assets and home ownership, debt and net worth usually vary according the householder's occupation. The ratios of debt repayment and the liquidity ratios also vary in part as age changes for each occupational group.

Major cardiovascular complications of diabetes are coronary atherosclerosis, diabetic dilated cardiomyopathy, autonomic neuropathy and those are major causes of morbidity and mortality in diabetic patients. Gated blood pool heart scan is noninvasive and useful method for evaluation of functional status of heart in diabetics. We evaluated 52 patients with diabetes and divided 3 groups. Group 1 were 11 patients without proteinuria or with proteinuria less than 550mng during 24 hours. Group 2 were 9 patients with proteinuria more than 550mg during 24 hours and group 3 were 32 patients with endstage renal diasese due to diabetes. We performed 99mTc-HSA cardiac gated blood pool scan and used left ventricular ejection fraction(LVEF), peak ejection rate(PEF) to indices of LV systolic function and peak filling rate(PER) to index of LV diastolic function. The results were follows : 1) LVEF, PER were significantly lower in diabetics with ESRD than diabetics without ESRD, but there were no significant difference between normal controls and diabetics without ESRD 2) PFR was significantly lower in diabetics than normal controls, but there were no significant differences in diabetics with or without nephropathy. 3) There were negative correlation between PER, PFR and duration of diabetes. On the basis of results, PFR is a LV functional index of GBPS which can disclose early change of LV dysfunction in patients with diabetes.

일본 동경만의 흐름양상과 생물플럭스의 분포특성을 역학-생태계모델을 통해 구현하고, 위성자료에서 얻어진 영상과 비교 분석하였다. 모델의 초기치와 경계치는 2001년 3월의 관측값들을 이용하였다. 운용된 모델 결과에서 얻어진 동경만의 흐름양상과 염분분포 등은 선행연구들과 대체로 일치하며 모델의 재현성을 어느 정도 신뢰할 수 있었다. NOAA/AVHRR에서 추정된 SST는 모델 결과에 비해 전체적인 분포양상은 아주 유사하였으나, 만입구에서 2.5℃정도, 내만에서 0.5℃ 정도 높게 추정되었다. 위성에서 얻어진 클로필-a 분포는 모델결과의 식물플랑크톤분포와 그 양상이 비슷하나, 농도는 상당한 차이가 나는 것을 확인할 수 있었다. 이러한 불일치에 관해서는 앞으로도 계속적인 연구가 수행될 예정이다. The hydro-dynamical and ecological coupled model were applied in the Tokyo Bay, to evaluate the flow pattern including water quality parameters and the distribution of biomass flux, and to compare with the results obtained from the satellite data during March 2001. The flow pattern and salinity distribution obtained from the present model were nearly identical with those of the previous studies. SST from NOAA/AVHRR was 2.5℃ higher than model reuslts in the mouth of bay and 0.5℃ lower than model results in inner bay, respectively. It was found that the concentration of chlorophyll-a estimated from SeaWiFS was considerably higher than that of model result, regardless similar distribution pattern. This disagreement will be studied through the more elaborate investigation in the future.

Distinction of antemortem changes from postmortem artifacts is of obvious importance in determining the cause of death. Problems in differential diagnosis may occur as a result of faulty autopsy technique, decomposition changes and destructive environmental factors. Recently we experienced a formation of tyrosine crystals on the gastric and esophageal mucosa of decomposed corpse. The tyrosine crystals found on the gastric and esophageal mucosa were very similar and small pin-head sized whitish gray granules. At first we suspected them as a certain drugs or toxic substances. But the granular materials were confirmed as tyrosine crystals by infrared spectrum analysis. So we report here as a first confirmed case in korea. We think the tyrosine crystal is formed by putrefactive processes and consider as one of the putrefactive artifacts.

Peritonitis is a serious problem in patients undergoing peritoneal dialysis. Rarely pneumatosis intestinalis can occur as a complication of this infectious process. Pneumatosis intestinalis is a potential life threatening condition with a challenging management. The mortality of peritoneal dialysis patients with pneumatosis intestinalis secondary to mesenteric ischemia is almost 100%. We describe a rare case of pneumatosis intestinalis in a peritoneal dialysis patient who developed Staphylococcus aureus peritonitis which was initially treated with appropriate antibiotics. Since initial response to therapy was not achieved, an abdominal computerized tomography was done which revealed a pneumatosis intestinalis. A laparotomy was performed and small bowel necrosis was seen. A segmented resection with ileostomy, jejunostomy was done. Though surgical treatment was performed, the patient died in 2 weeks after admission. Pneumocystitis intestinalis in peritoneal dialysis peritonitis is a uncommon complication which requires prompt evaluation to rule out mesenteric ischemia as it carries a high mortality and its management will be surgical.
