Purpose: The aim of this study was to evaluate the effect of lumbar stabilization exercise on an unstable surface on trunk posture and static standing balance ability in patients with scoliosis. Methods: Subjects included 18 patients who showed symptom of scoliosis. Patients were divided into two experimental groups, one using an unstable surface and one using a fixed surface, and the patients were required to perform a lumbar stabilization exercise a total of 12 times for 60 minutes per session, three times per week for a period of four weeks, with a six-months follow-up period. Results: A significant reduction was observed in the group that performed the lumbar stabilization exercise on an unstable surface (p<0.05). A significant decrease in both the condition of closed eyes or open eyes in the left and right directions was observed in the group that performed the lumbar stabilization exercise on an unstable surface (p<0.05). After six months, results of comparison of the length of both sides of the trunk showed a significantl decrease in the group performing lumbar stabilization exercises on an unstable surface. Conclusion: Lumbar stabilization exercise on an unstable surface improved the trunk posture of patients with scoliosis symmetrically, and static balance ability in a standing posture showed improvement. In the future, lumbar stabilization exercise on an unstable surface may be used as an exercise for posture correction and balance increase for patients with scoliosis.

본 연구에서는 남해안 해성점토의 일정변형률 압밀특성을 파악하기 위해 표준압밀시첩과 변형률 속도가 다른 일정변형율 압밀시험을 수행하고 이들 결과를 비교.분석하였다. 표준압밀시험 및 일정변형율 시험에서 선행압밀하중을 산정하기 위하여 여러 제안된 방법을 사용하였으며 각 방법의 적용성을 검토하였다. 또한, 변형률 속도가 응력-변형뮬 관계, 간극수압, 그리고 선행압밀 하중에 미치는 영향을 분석하였다. 해석결과에 의하면 압밀곡선의 분포와 선행압밀하중비($a_2=\sigma'_{pCRS}/\sigma'_{pConv}$)는 변형률 속도의 영향을 받지만, 정규압 밀구간의 압축지수는 상대적으로 변형률 속도의 크기와 무관한 것으로 나타났다. 해성점토의 선행압밀하중비는 변형률 속도의 대수축척에 비례하여 증가하는 것으로의 변형률 속도에서 평균적으로 1.11~1.30의 분포를 보였다. 일정변형률 압밀시험에서 간극수압비는 변형플 속도가$6.67\times10^{-4}$ %sec일 때를 제외하고는 6.0%를 초과하지 않는 것으로 나타났다. 정규압밀구간의 압축지수, 압밀계수와 투수계수는 각각 0.59~0.95, $0.56\times10^{-3}~3.0\times10^{-3} cm^2/sec,\; 그리고 \;2.0\times10^4~7.0\times10^{-4} cm/sec$의 분포를 보였다. A series of conventional tests and CRS consolidation tests with different rates of strain were performed to investigate the consolidation characteristics of marine clay. Preconsolidation pressures were evaluated by applying previously proposed methods for both the conventional tests and CRS tests results in order to check the legitimacy of those methods. The effects of strain rate on effective consolidation stress strain relationship, porewater pressure, and preconsolidation pressure were also discussed It was found that the effective stress strain relationship and the preconsolidation pressure are a function of strain rate imposed during consolidation test, but compression index isn't. The preconsolidation pressure ratio ($a_2=\sigma'_{pCRS}/\sigma'_{pConv}$)of marine clay appears proportional to the logarithm of strain rate, with average values ranging from 1.11 to 1.30 for strain rates between $1\timesx10^{-4} %/sec\; and\; 4\times10 %/sec$. The porewater pressure ratio during CRS teats does not exceed 6.0% except when the strain rate is $6.67\times10^{-4} %/sec$. Coefficient of consolidation or coefficient of permeability at normally consolidated range was not affected by the type of consolidation tests and the strain rate. Typical values of compression index (C.), coefficient of consolidation(c.), and coefficient of permeability (k.) at normally consolidated range were 0.56-0.95, $0.56\times10^{-4}~3.0\times10^{-4}cm2/sec,\; and\; 2.0\times10^{-8}~7.0\time10^{-4}cm/sec,$ respectively.

This paper examines how faithful to their ideology Korean voters have been in recent Korean elections; they are the local election of 2006, the presidential election of 2007, the general election of 2008, and the local election of 2010. We used the panel studies surveyed by the East Asia Institute-SBS-JoongAng Daily Election Studies Team. We find that a vast majority of Korean voters were very clear about ideology positions of political parties (or candidates) as well as their positions, and voted for the party or the candidate whose ideology position is closest to theirs. The fraction of voters who voted for the party or the candidate whose ideology position is closest to theirs is increasing over time; the ratio of voters who voted faithfully to his/her ideology is 52.6% in 2006, 55.8% in 2007, 64.9% in 2009, and 70.1% in 2010. The degree of ideology-faithfulness does not significantly differ across genders, education levels, income levels, and religions, but differ across age groups and ideology groups. The more aged and the more conservative is a voter, the higher the degree of ideology-faithfulness he/she has.

Background: Neutrophilic airway inflammation has been reported in severe intractable asthma. Therefore, direct assessment of airway inflammation may be useful. However, but it is not easy especially in patients with acute asthma. Objective: To investigate whether the clinical characteristics of patients with acute asthma differ according to the cellular profiles of their blood samples which are easily obtainable. Method: The medical records of 410 adult patients with acute asthma, who were hospitalized between 2002 and 2007, were reviewed. Blood eosinophilia and neutrophilia were defined as the cell counts of ≥450/μL and ≥7,500/μL, respectively. Result: The patients with eosinophilia were relatively young, and they had high serum levels of total IgE and posttreatment lung function. The patients with neutrophilia showed a significantly lower posttreatment lung function and a higher prevalence of emphysema than those with eosinophilia. The levels of PaCO2 were significantly related to the eosinophil counts, while the levels of PaO2 and C-reactive protein (CRP) were related to the neutrophil counts(all P<0.01). Conclusion: Eosinophilic or neutrophilic response in peripheral blood which occur in acute asthma patients may depend on upon the attack severity and clinical characteristics of subjects such as allergy or irreversible airflow obstruction.

Background/Aims: The aims of this study were to investigate the prevalence of significant fibrosis in patients with chronic hepatitis B (CHB) virus infections and alanine aminotransferase (ALT) <80 IU/L, and to develop a noninvasive predictive model for significant fibrosis. Methods: The 136 patients with CHB who underwent liver biopsy were recruited from six tertiary hospitals. The diagnostic value of predictors was judged using multivariate logistic modeling and the area under the receiver operating characteristic (AUROC) curve. Results: Significant fibrosis was diagnosed in 97 patients (71.3%, 95% CI, 63.7~78.9%). In the training set (n = 85), the most important clinical data for predicting significant fibrosis were age and aspartate aminotransferase (AST). The AUROC of this model was 0.86 (95% CI, 0.78~0.94). The validation set (n=51), obtained from another institute, yielded similar results [AUROC: 0.90 (95% CI, 0.78~0.99)]. Conclusions: A high prevalence of significant fibrosis in CHB patients with ALT <80 IU/L was observed. A simple model that includes age and AST provides an easily applicable tool for physicians to guide the decision-making process regarding the need to perform a liver biopsy in individual patients. However, additional studies are needed to explore the model`s performance in larger, independent patient populations. (Korean J Med 78:68-74, 2010)

목적: 비대상성 간경변증 환자에서 3개월과 12개월 시점의 간정맥압차와 MELD의 사망예측 정확도를 비교하여, HVPG의 예후인자로서의 역할을 확인하고자 하였다. 대상과 방법: 2006년 1월부터 2008년 6월까지 한림대학교부속 춘천성심병원에서 136명의 비대상성 간경변증 환자를 대상으로 HVPG를 측정하였다. 생존분석의 1차 결과 변수로서 3개월과 12개월에서의 사망 여부를 확인하였다. 결과: Cox 회귀분석 결과, MELD와 HVPG 모두 독립적인 예후인자로 확인되었다[각각 hazard ratio는 1.11(95% CI, 1.04 to 1.20)과 1.12(95% CI, 1.08 to 1.16)]. 두 변수의 ROC곡선의 AUC를 비교해 볼 때, 3개월에서 유의하진 않지만 MELD는 HVPG보다 사망예측에 있어서 정확도가 8% 정도 더 높게 보였다[0.76(95% CI, 0.62 to 0.89) 대 0.68(95% CI, 0.52 to 0.84), P=0.22]. 12개월에서는 MELD와 HVPG 모두 비슷한 사망예측의 정확도를 보였다[0.72(95% CI, 0.61 to 0.83) 대 0.73 (95% CI, 0.61 to 0.84), P=0.45,]. 결론: MELD와 HVPG는 비대상성 간경변증 환자에서 사망과 관련된 독립적인 예후인자로서 사망예측의 정확도에 있어서 유의한 차이를 보이지 않는다. 하지만 HVPG는 침습적이고 소수의 의료기관에서만 시행된다는 점에서 사망예측인자로서 HVPG의 역할은 제한적이라 판단된다. 그러나 HVPG의 다양한 예후인자로서의 임상적 역할을 규정하기 위해서는 폭넓은 환자군(원인, 성별, 지역, 등)을 대상으로 하는 전향연구가 필요하다. Backgrounds/Aims: This study compared the prognostic values of the Model for End-stage Liver Disease (MELD) and the hepatic venous pressure gradient (HVPG) in the prediction of death within 3 and 12 months in patients with decompensated liver cirrhosis. Methods: We used data from 136 consecutive patients with decompensated cirrhosis who underwent HVPG between January 2006 and June 2008. Cox regression analysis was used to investigate the independent relationships with death of MELD and HVPG. The prognostic accuracies of MELD and HVPG were analyzed by calculating the area under the receiver operating characteristic curve (AUROC) for the occurrence of death within 3 and 12 months. Results: Both MELD and HVPG were independent predictors of death [hazard ratio (HR)=1.11 and 1.12, respectively; 95% confidence interval (CI)=1.04~1.20 and 1.08-1.16]. Analysis of the AUROC demonstrated that the prognostic power did not differ between MELD and HVPG for predicting the 3-month survival (HR=0.76 and 0.68, respectively; 95% CI=0.62~0.89 and 0.52~0.84; P=0.22) or the 12-month survival (HR=0.72 and 0.73, 95% CI=0.61~0.83 and CI=0.61~0.84). Conclusions: Both MELD and HVPG are independent prognostic factors of death within 3 and 12 months in patients with decompensated liver cirrhosis, and their accuracies are similar. However, HVPG has a limited role in the prediction of death in decompensated cirrhosis due to its invasiveness and limited use. (Korean J Hepatol 2009;15:350-356)
