The aim of this study is to determine whether full-mouth disinfection therapy(FMT) in our clinical setting would show better improvement of clinical parameters than partial mouth disinfection therapy(PMT) in chronic periodontitis and aggressive periodontitis patients. Among 12 patients, 6 were treated FMT and other 6 were treated PMT. Clinical parameters were calculated 3 months and 6 months after initial therapy. 1. There were no statistically significant differences between FMT and PMT in the reduction rate of bleeding on probing after 3 months, 6 months 2. Initial probing depth was 4-6mm, the mean probing depth after 3 months was 2.2mm vs 2.5mm(FMT vs PMT), after 6 months was 2.4mm vs 2.8mm. This was significantly lower in the FMT groups. 3. Initial probing depth was ${\geqq}$ 7mm, the reduction rate of mean probing depth during first 3 months was 4.8mm vs 4.1mm(FMT vs PMT), and 3 to 6 months was 0.5mm vs 0.3mm. This was significantly larger in the FMT groups. 4. Initial probing depth was 4-6mm, the mean clinical attachment level after 3 months was 2.3mm vs 2.7mm(FMT vs PMT), after 6 months was 2.7mm vs 3.0mm. This was significantly lower in the FMT groups. 5. Initial probing depth was ${\geqq}$ 7mm, the reduction rate of mean probing depth during first 3 months was 4.0mm vs 3.0mm(FMT vs PMT), and 3 to 6 months was 0mm vs -0.1mm. This was significantly larger in the FMT groups. Although the results provided us with succeccful clinical improvement in aggressive periodontitis, further research is needed to prove its additional benefit in the treatment of chronic periodontitis

In this paper, we analyze the characteristics for the driving shock resistance of the military vehicle through the bump test. Prior to the experiment, theoretical analysis was performed by using the SRS(shock response spectrum) and VRS(vibration response spectrum) analysis method. And we estimated the characteristics for the driving shock resistance of the military vehicle. Bump test was performed using the acceleration sensor and the driving test at a different speed. We evaluated the characteristics for the driving shock resistance of the military vehicle based on the result. And predicted values were compared with the theoretical analysis. In addition, we evaluated the results of the theoretical prediction of the SRS and the VRS analysis. And we evaluate the suitability of the prediction method at military vehicle shock analysis.

지속성 외래 복막투석 환자에서 C반응단백, 맥압과 관상동맥질환의 관계

목적 : 말기신부전으로 투석 중인 환자에서 C반응단백 (C-reactive protein, CRP)은 이환률과 사망률의 주요한 원인으로 알려진 관상동맥질환을 예견하는 지표로 알려져 있으며, 최근 여러 연구에서 맥압의 증가가 정상인에서 심혈관 질환과 사망률의 위험인자로 대두되고 있다. 따라서 본 연구는 복막투석 환자에서 이 두 가지 지표를 함께 측정하여 관상동맥질환의 위험도를 예견하는 지표로서의 가치를 알아보고자 시행되었다. 방법 : 복막투석을 시행하는 환자 중 thallium single photon emision computed tomography (thallium SPECT)를 시행하고 6개월 이상 추적관찰이 가능하였던 총 71명의 환자 (남자 42명, 여자 29명)를 대상으로 하였다. 나이, 성별, 흡연, 당뇨, 고혈압, 맥압, 체질량 지수에 대하여 조사하였으며 혈중 알부민, 총 콜레스테롤, 섬유소원, lipoprotein (a), C반응단백을 검사 하였다. 결과 : Thallium SPECT 양성군과 음성군으로 분류하여 비교한 결과 thallium SPECT 양성군에서 C반응단백, 맥압, 흡연율, 섬유소원의 값이 의의있게 높았다 (p<0.05). 맥압이 1 mmHg 증가시 관상동맥질환의 상대 위험도는 1.017배 (95% 신뢰구간 1.011-1.023), C반응단백이 0.01 mg/dL 증가시 관산동맥질환의 상대 위험도는 1.014배 (95% 신뢰구간 1.008-1.019) 증가하였다. 다증회귀분석 결과 C반응단백과 맥압이 심근 허혈에 영향을 주는 독립인자였다. Log C반응단백과 맥압간에는 양의 상관관계가 있었다. (p<0.01>. 결론 : 복막투석 환자에서 C반응단백과 맥압은 모두 관상동맥 질환을 예측하는데 유용한 지표로 이용할 수 있을 것으로 기대된다. 그러므로 복막투석 환자에서 뚜렷한 원인 없이 지속적으로 C반응단백과 맥압이 상승되어 있는 경우 허혈성 심질환에 대하여 검사가 이루어져야 할 것으로 생각된다. Background : Atheroclerotic vascular disease is the major cause of morbidity and mortality in dialysis patients. C-reactive protein (CRP) appears to be clinically useful in prediction of coronary heart disease. Elevated pulse pressure has been associated with an increased risk of cardiovascular disease among apparently healthy adults. Therefore, we evaluated the association between a persistent elevation of C-reactive protein level, pulse pressure and the presence of ischemic heart disease in patients with continuous ambulatory peritoneal dialysis (CAPD). Methods : A total of 71 CAPD patients (42 males 29 females) who underwent thallium SPECT and followed up more than 6 months were included. We collected the data about age, sex, smoking, diabetes, hypertension, pulse pressure and body mass index. Blood levels of albumin, total cholesterol, fibrinogen, lipoprotein (a) and C-reactive protein were measured. Results : The values of C-reactive protein, pulse pressure, smoking and fibrinogen were significantly higher in thallium SPECT positive group (p<0.05). A 0.01 mg/dL increase in C-reactive protein was associated with a 1.014 increase in the odds of having an elevated risk of coronary artery disease (95% confidence interval 1.008-1.019) and a 1 mmHg increase in pulse pressure was associated with a 1.017 increase in the odds of having an elevated risk of coronary artery disease (95% confidence interval 1.011-1.023). By multivariate logistic regression analysis, C-reactive protein and pulse pressure were independent risk factors for ischemic heart disease. Log CRP level was positively correlated with pulse pressure level (p<0.01). Conclusion : The baseline level of CRP and pulse pressure independently predicts the risk of coronary heart disease in CAPD patients. For patients who have a persistent elevation of CRP and pulse pressure without an apparent cause, we recommend a workup for ischemic heart disease.
