이경규,이지영,김현우,이정엽,백기청,김재일,이근호 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.5

연구목적 : 어지럼증을 호소하는 환자들 중에 심인성 어지럼증 환자가 상당수 있다는 것은 알려져 있고, 이러한 심인성 어지럼증과 동반되는 정신질환으로는 불안장애, 우울장애, 인격장애 등이 있다. 이에 본 연구에서는 심인성 어지럼증 환자들의 빈도와 정신과적 증상을 알아보고자 하였다. 방 법 : 어지럼증 환자들에게 평형검사, 자세운동측정검사, 자세변화검사, caloric testing을 시행하여 심인성, 말초성 및 중추성의 3군으로 분류한 후 각각 14명, 16명, 32명을 대상으로 하였다. 대상환자들에게 한국판 Beck 우울척도검사(K-BDI), Spielberg의 상태-특성 불안검사(STAI). 간이정신진단검사(SCL-90-R)를 이용하여 정신과적 증상을 측정하여 이들 세 군을 비교분석하였다. 결 과 : 1) 심인성 어지럼증을 가진 환자는 어지럼증을 나타내는 환자 총 62명중에서 14명으로 22.6%를 차지하였다. 2) K-BDI에 따른 세 군간의 비교에서는 세 군간에 유의한 차이를 보이지 않았다. 3) STAI에 따른 세 군간의 비교에서 상태불안(STAI-S) 및 특성불안(STAI-T) 모두에서 세 군간에 유의한 차이를 보이지 않았다. 4) SCL-90-R에 따른 세 군간의 비교에서는 9개의 척도 중에서 공포불안척도에서만 중추성 어지럼증군이 47.56±6.90, 말초성 어지럼증 군이 53.50±13.74, 심인성 어지럼증 군이 58.50±16.05로 심인성 어지럼증 환자군이 중추성 어지럼증 환자군에 비하여 유의하게 높은 것으로 나타났다(p<0.01). 5) 통증 증상에 있어서는 세 군간에 유의한 차이를 보이지 않았고, 위장관 증상과 성기능 장애 증상은 중추성과 말초성 어지럼증 군이 심인성 어지럼증 군에 비하여 유의하게 높은 것으로 나타났다(p<0.01). 결 론 : 상기 결과를 토대로 했을 때 어지럼증 환자들에 대한 정신과적 접근을 위하여 각 군을 나누는 것은 별 의미가 없으며 어지럼증 환자들의 어지럼증 자체에 대한 직접적이고 집중적인 치료가 더욱 필요할 것으로 생각된다. Objectives : This study was aimed to investigate psychiatric symptoms in patients with psychogenic dizziness and compare these findings with those of patients with central and peripheral dizziness. Methods : A total of 62 patients with dizziness was the subject of investigation, and patients were classified into 32 with central type, 16 with peripheral type, and 14 with psychogenic type. Korean standardized Beck Depression Inventory(K-BDI), State and Trait Anxiety Inventory(STAI), and Korean standardized edition of Symptom Checklist 90 Revised(SCL-90-R) were used for the assessment. Statistically, Pearson's chi-square test and one-way ANOVA with Scheffe's test were used with SPSS/PC for windows 6.0. Results : The results were as follows : 1) The proportion of psychogenic dizziness was 22.6% of the total subjects. 2) Total scores of K-BDI were not significantly different among the 3 groups. 3) Total scores of state anxiety and trait anxiety were not significantly different among the 3 groups. 4) In SCL-90-R, psychogenic dizziness group showed significantly higher score of phobic anxiety only(p<0.01) than central dizziness group. And others were not significantly different among the 3 groups. 5) In additional somatic symptoms, pain score was not different among the 3 groups, but gastrointestinal and sexual symptoms scores of central and peripheral dizziness group were significantly higher than those of psychogenic dizziness group(p<0.01). Conclusion : These results suggest that psychiatric symptoms in patients with psychogenic dizziness are not different from those of patients with central or peripheral dizziness. Therefore, the more direct and intensive treatment may be necessary regardless of the type of dizziness.

UKF를 이용한 정전용량형 수동센서시스템의 파라메타 추정

김경엽,이준탁 東亞大學校附設 淸報技術硏究所 2006 情報技術硏究所論文誌 Vol.13 No.2

In this paper, a noisy passive telemetry sensor system using Unscented Kalman Filter (UKF) is proposed. To overcome these trouble problems such as a power limitation and a estimation complexity that the general passive telemetry sensor system IC chip has, the principle of inductive coupling was applied to the modelling of a passive telemetry sensor system (PTSS) and its noisy capacitive parameter was estimated by the UKF algorithm in time domain. Specially, to show the effective tracking performance of the UKF, we compared with the tracking performance of Recursive Least Square Estimation (RLSE) using linearization.

화농성 심장막염은 전 세계적으로 매우 드물고 사망률이 높은 질환이다. 화농성 심장막염은 대부분 심장막을 침범하지만, 국소적으로 농양을 형성하는 경우도 보고 되고 있다. 세균에 의한 화농성 심장막염은 전체 급성 심장막염의 원인 중 6% 정도를 차지하고 있다. 그 중에서 혐기균에 의한 화농성 심장막염은 호기균에 의한 것보다 훨씬 드물다. 저자들은 만성 신질환으로 혈액 투석을 받고 있는 58세 남자에서 발생한 B. fragilis에 의한 화농성 심장막 농양과 심장눌림증을 국내에서 처음으로 경험하였기에 이를 고찰과 함께 보고하는 바이다. Purulent pericarditis is a rare, life-threatening condition and usually ivolves the whole pericardium. However only few cases have been reported in which a loculated pericardial abscess occurred from purulent pericarditis. The prevalence of acute pericarditis due to bacteria was 6%. Purulent pericarditis due to anaerobic bacteria has been reported less frequently than aerobic bacteria. There was no report about purulent pericarditis due to Bacteroides fragilis in Korea until now. So we report the first case of pericardial abscess due to B. fragilis in 59 year old Korean male with history of chronic renal failure and hemodialysis, that was complicated with pericardial tamponade.

Bony defects of mandible caused by trauma, infection, or tumor resection have been reconstructed by autologous bone graftings. These reconstruction can restore facial contour and integrity of the oral cavity. However, it is often necessary to reduce the bulk of bone to allow soft tissue coverage of the graft. Therefore, the construction of removable dentures in this situation is fraught with frustation. The use of osseointegrated implants is a method to allow improved anchorage and support for the successful fabrication of dental protheses. We report two cases of the use of osseointegrated implants of the Branemark type(3i), in conjunction with bone grafting to the lower jaw.

저자들은 특별한 위험 인자 없이 심한 허리 및 왼쪽 둔부 통증으로 내원하여 황색포도알균에 의한 균혈증이 진단된 젊은 여성에서 드문 감염질환인 화농성 천골장골관절염과 엉덩근 및 엉덩허리근 농양이 발생된 예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Pyogenic sacroiliits is a rare disease and the diagnosis is difficult because of unawareness of the disease and nonspecific symptoms and signs mimicking septic hip, iliopsoas muscle abscess and herniation of intervertebral disk. There are some predisposing factors related to the disease like trauma, pregnancy, intravenous drug abuse and infection of other systems such as skin, genitourinary system and heart. Staphylococcus aureus is the most common causative bacteria. Here we describe a case of 27-year-old woman presented with acute onset of back and left buttock pain. Bone scintigraphy revealed increased uptake at left sacroiliac joint and computed tomography of the pelvis showed left sacroiliitis with left iliacus and iliopsoas abscess. There was no history of usual predisposing conditions. S. aureus was grown from blood cultures and the patient improved with 2 weeks of intravenous cefazolin followed by 4 weeks of oral clindamycin treatment.

<P>This study was conducted to investigate the associations between polymorphisms of genes involved in the LKB1 pathway and the prognosis of patients with non‐small cell lung cancer (NSCLC) after surgical resection. Twenty‐three single nucleotide polymorphisms (SNPs) in the LKB1 pathway were investigated in 782 patients with NSCLC who underwent curative surgery. The association of SNPs with overall survival (OS) and disease‐free survival (DFS) were analyzed. Among the 23 SNPs investigated, <I>TSC2</I> rs30259G > A was associated with significantly worse OS and DFS (adjusted hazard ratio for OS 1.88, 95% confidence interval 1.21–2.91, <I>P</I> = 0.005; adjusted hazard ratio for DFS 1.65, 95% confidence interval 1.15–2.38, <I>P</I> = 0.01, under codominant models, respectively). Subgroup analysis showed that SNPs were significantly associated with survival outcomes in squamous cell carcinoma, ever‐smokers, and stage I, but not in adenocarcinoma, never‐smokers, and stage II–IIIA. The results suggest that <I>TSC2</I> rs30259G > A may be useful to predict prognosis in patients with NSCLC, especially squamous cell carcinoma, after curative surgery.</P>

<P><B>Abstract</B></P> <P>This study was conducted to explore whether polymorphisms of glucose transporter 3 (<I>GLUT3</I>) gene affect the prognosis of patients with non-small cell lung cancer (NSCLC) after surgical resection. Four single nucleotide polymorphisms (SNPs) in <I>GLUT3</I> were investigated in a total of 782 patients with NSCLC who underwent curative surgery. The association of the SNPs with overall survival (OS) and disease free survival (DFS) was analyzed. Among the four SNPs investigated, <I>GLUT3</I> rs7309332C>T was significantly associated with OS and DFS in multivariate analyses. The SNP was associated with significantly worse OS (adjusted hazard ratio [aHR] = 1.62, 95% confidence interval [CI] = 1.04–2.53, <I>P</I> = 0.03, under recessive model), and worse DFS (aHR = 1.64, 95% CI = 1.18–2.29, <I>P</I> = 0.003, under recessive model). When stratified by tumor histology, the association between the <I>GLUT3</I> rs7309332C>T and OS/DFS was not limited to either squamous cell carcinoma (SCC) or adenocarcinoma (AC), although the significant association remained only in AC for OS (<I>P</I> = 0.40 for SCC and <I>P</I> = 0.04 for OS) and only in SCC for DFS (<I>P</I> = 0.03 for SCC and <I>P</I> = 0.08 for OS). When AC patients were stratified according to <I>EGFR</I> mutation status, the SNP was significantly associated with DFS in patients with <I>EGFR</I> mutant tumors (aHR = 2.47, 95% CI = 1.15–5.30, <I>P</I> = 0.02, under recessive model), but not in those with <I>EGFR</I> wild-type tumors. This study suggests that genetic variation in <I>GLUT3</I> may be useful in predicting survival of patients with early stage NSCLC.</P> <P><B>Highlights</B></P> <P> <UL> <LI> <I>GLUT3</I> variant was significantly associated with survival of NSCLC after surgery. </LI> <LI> The association was not limited to either squamous cell carcinoma or adenocarcinoma. </LI> <LI> The SNP may help identify patients at high risk of poor outcome in early stage NSCLC. </LI> </UL> </P>

Evaluation of DoP-CPD Classification Technique and Multi Looking Effects for RADARSAT-2 Images

Lee, Kyung-Yup,Oh, Yi-Sok,Kim, Youn-Soo The Korean Society of Remote Sensing 2012 大韓遠隔探査學會誌 Vol.28 No.3

This paper give further assessment on the original DoP-CPD classification scheme. This paper provides some additional comparative study on the DoP-CPD with H/A/alpha classifier in terms of multi look effects and classification performances. The statistics and multi looking effects of the DoP and CPD were analyzed with measured polarimetric SAR data. DoP-CPD is less sensitive to the number of averaging pixels than the entropy-alpha technique. A DoP-CPD diagram with appropriate boundaries between six different classes was then developed based on the data analysis. A polarimetric SAR image DoP-CPD classification technique is verified with C-band polarimetric RADARSAT-2 images.
