신장내과를 전문 과목으로 선택하여 대학병원에서 10여년 가까이 환자를 진료하면서 아침에 회진을 할 때면 저는 전공의 들에게 "어제 입원한 환자는 당뇨병성 신증 환자인가"라고 먼저 묻는 경우가 많습니다. 그 이유는 당뇨병으로 합병된 신장병, 혹은 당뇨병환자에서 혈관질환과 감염 질환이 동반될 경우 치료도 어렵고 임상 경과가 악성 경과를 밟으며 예후가 좋지 않기 때문입니다. 또한 당뇨병으로 인한 말기 신부전증이 최근 무섭게 증가되고 있기 때문이기도 합니다. 따라서 당뇨병성 신증의 조기 발견과 적절한 치료는 아무리 강조해도 지나침이 없습니다. 저는 여기서 최근 가장 가슴이 아팠던 사례를 간단히 소개하고 당뇨병성 신증의 원인, 예방과 치료를 서술하고자 합니다.

현재 쯔나미의 계산에 있어서 수치계산의 안정성이나, 파형의 재현을 고려하기 위한 기준 등은 제시된 바 있다. 대표적인 예로 CFL 안정조건과 같이 계산의 불안정을 방지하기 위한 기준을 비롯하여 한 파장내에 적어도 20개의 공간격자를 확보하여야 한다는 등의 기준(Shuto,1991)이 그것이다. 또한, 쯔나미의 거동특성 중 하나인 분산현상에 대해서도 Imamura 등(1988)은 수치분산의 영향을 추정하였고, 저차방정식으로부터 고차의 근사해를 구하는 등의 수법을 제안하기도 하였다. (중략)

Serum lipid peroxide levels in 25 chronic renal failure patients undergoing hemodialysis were examined by determining TBA reaction with spectrofluorometry. The lipid peroxide levels, 208.9$\pm$88.4nmol/ml, in the patient group was significantly higher than 152.4$\pm$43.9nmol/ml of 48 control healthy subjects. It is likely that the elevated serum lipid peroxide levels can play a role in increasing tendency of hemorrhage and incidence of atherosclerosis in chronic renal failure patients.

치주치료의 궁극적 목표인 치주조직 재생에 대한 관심이 높아지는 가운데 치주조직 재생에 주된 역할을 하는 치주인대세포와 치근면 탈회에 의한 신부착 효과에 관한 많은 연구가 시도되고 있다. 그러나 광범위한 연구에도 불구하고 어떤 치근면 처리가 신부착 형성에 가장 효과적인지는 아직 논란의 대상으로 남아있다. 이에 저자는 결합조직 부착에 의한 재생에 필수적인 치은 및 치주인대 섬유아세포의 부착 및 증식을 tetracycline-HCL(TC)과 citric acid(CA)로 각각 처리된 상아질 표면에서 비교관찰하여 치주조직 재생에의 기여도를 추정하기 위해 본 연구를 시행하였다. 교정치료를 위하여 본원에 내원한 환자의 제일 소구치의 건강한 치은조직을 채취하고, 발치 후 효소처리에 의한 치주인대세포를 얻은 후 각각 세포배양하였다. 상아질 절편은 $3{\times}3{\times}0.2mm^3$로 준비하고 TC과 CA처리군으로 나눈 후 각각 치은 및 치주인대 섬유아세포를 부착시키고 초기부착은 8시간까지, 증식은 7일까지 고나찰하여 다음의 결과를 얻었다. 1. 각 군의 세포 부착은 시간이 지남에 따라 증가되었다. 2. 모든 군에서 7일째 빠른 증식상을 보였다. 3. 초기 부착시 치은과 치주인대 섬유아세포의 반응에는 유의한 차이가 없었다. 4. 반면에 치은과 치주인대 섬유아세포는 증식속도에서 차이를 나타내었으며 치은 섬유아세포가 좀 더 빠른 성장을 보였다. 5. 치근면 탈회에 따라 초기부착과 증식상에서 모두 유의성 있는 증가를 보였다. 6. CA는 초기부착에서, TC는 증식장에서 더욱 효과적으로 작용했다.

This study attempts to provide fundamental information for a health policy and health services by looking at the trends and types of the mortality rates in Korea and Japan. In this study, data of the death statistics of Korea and Japan over the 21-year period from 1983 to 2003 are analyzed. Mortality data are standardized ${\times}100,000$ to the 2003 Japan population, according to the direct method. In 2001/2003, the ranking of major causes of death in Korea and Japan has been greatly changed. In Korea, mortality rates from malignant neoplasms, diabetes mellitus, renal failure, falls and suicide have increased. In Japan, the mortality rates from pneumonia increase more than those from diabetes mellitus. In 2001/2003, the proportions of the mortality rates from chronic diseases are higher than those from acute diseases. In the Korean health promotion policy "Health Promotion 2020", a more intensive goal management is needed.

Purpose: To examine the levels of the disease-related knowledge and educational demands of pre-dialysis, chronic renal failure patients at different GFRs and stages. Methods: This study used a cross-sectional survey and aimed at 116 pre-dialysis, chronic renal failure patients, who were registered and received regular treatment from December 1 to December 31, 2009 at the nephrology departments of tertiary medical centers in Seoul. Stages were classified into Stage 3, 4 and 5 depending on GFR ranges. To measure the levels of knowledge and educational demands, the tool, which were first invented by Young Ae Lim (1996) and then modified by Hyo Sun Lim (2005) to adjust the knowledge and educational demands measuring tool for hemodialysis patients to pre-dialysis patients with chronic renal failure, was used. Collected data was analyzed with the SPSS WIN 12.0 program (average, standard deviation, Pearson's correlation coefficient, t-test and ANOVA). Results: There was a significant difference in the disease-related knowledge levels of the subjects at each stage (F=24.41, p=.000). The Scheffe post hoc test confirmed that patients at higher stages had higher levels of knowledge of their disease. Also, although the results showed that patients at higher stages had higher educational demands, there was no significant difference among the groups (F=1.259, p=.288). Conclusion: As patients have different levels of knowledge of the disease and educational demands depending on their stages, it is important to develop and use a systematic education program that reflects the demands and levels of patients at each stage in order to help pre-dialysis patients with chronic renal failure with self-management and improve their quality of life.

A 51-year-old male with chronic renal failure had marked swelling and tenderness of the right arm. Venography revealed central vein occlusion involving stenosis of right proximal subclavian vein, right internal jugular vein, and left distal innominate vein, and obstruction of right brachiocephalic vein. Multiple obstruction of these veins was thought to have resulted from repeated subclavian catheterization. Right subclavian-superior vena cava was bypassed with 10 mm Gore-tex vascular graft and then left subclavian vein with 8 mm Gore-tex vascular graft was bypassed to the 10 mm Gore-tex vascular graft. The results were excellent.

In this paper, we propose a method of analysing the relation between the patient's face color and his(her) kidney disease using image processing technology. This method is based on the ocular inspection which is one of the most famous diagnosis methods used in the oriental medical system. The way of processing and analysing the face image, which is for visualization and objectification of the color difference, is included. The objects are selected from the patients who suffer the kidney disease and use the hemodialyzer. Their facial images and clinical data are collected. From these data, we propose a hypothesis that the color of the patient's face is changed according to the patient's kidney state. At the same time, we present two algorithms of extracting the specific part of face which can identify the state of the patient's kidney and tracing the history of the color's change. This proposed method is evaluated through the practical experiments and their analysis.

OFDM(Orthogonal Frequency Division Multiplexing)is a one of the nst promising digital modulation techniques adapted for Digital audio broadcasting or Digital TV since it is very robust against multipath fading channels. From 1997, since the OFDM technique was considered as the physical layer standard for the high data rate wireless LAN systems in the 5㎓ band, related studies have been studied actively. The key element to implement high data rate wireless LAN system using OFDM technique are IFFT and FFT modules. In this paper, new IFFT and FFT module are designed and implemented using current cut circuit based on the matrix-rounding process for the low-power consumptive operation and high-speed data processing. In addition to, we certify the available operation of the rounded IFFT/FFT module in the AWGN channel by using the BER performance simulation of IEEE 802.11TGa based OFDM modem with rounded IFFT/FFT module.
