Purpose: The purpose of this study was to analyze the correlation between medial joint space on Rosenberg view and the degree of ultrasonographic medial meniscal extrusion. Materials and Methods: Three hundred ninety knees with medial joint tenderness examined by ultrasonography were reviewed between January 2009 and May 2010. Medial joint space was divided into Grade I (${\geq}$ 4 mm), Grade II (3~4 mm), Grade III (2~3 mm), Grade IV (1~2 mm) and Grade V (0~1 mm). Then sonographaphic mid-medial extrusion of the medial meniscus was measured in each patient. After dividing into Group A that didn't have large osteophytes (${\geq}$ 3 mm, medial joint at tibia) and Group B that had them, the correlation between the medial joint space and medial meniscal extrusion were analyzed in each group. One-way ANOVA & Scheffe test on the SAS program were used for the statistical analysis (p<0.05). Results: There was a positive correlation between grade of the joint space and medial meniscal extrusion in Group A, but there was no positive correlation in Group B (p<0.05). Conclusion: To the patients who didn't have advanced osteoarthritis, the narrowing of the medial joint space was one of the predictive factors for mid-medial extrusion of the medial meniscus.

This paper describes a method of Korean speech synhes is using format VOCODER. The parameters of speech synthes is are a follows, 1) format F1, F2, and F3 by spectrum moment method and F4, F5 using the length of vocal tract. 2) pitch frequencies obtained by optimu, Comb method using AMDF. 3) short time average energy and short time mean amplitude. 4) The decision method of bandwidth reportd by Fant. 5) voicde/unvoiced discrimination using zerocrossing. 6) excitation wave reported by Rosenberg. 7) gaussian white noise. Synthesis results are in fairly good agreement with original speech.

Objectives : This study was designed for the purpose of the relationship between psychopathology and suicide in North Korean Refugee Adolescents. Methods : The subjects were 104 North Korean Refugee Adolescents. We investigated the The Korean version of the Center for Epidemiologic Studies for Depression, Revised Children's Manifest Anxiety Scale and Rosenberg Self-Esteem Scale. We also investigated the suicide ideation, planning and attempt. The self-report was taken to the North Korean Refugee Adolescents. Results : The Center for Epidemiologic Studies for Depression Score(Z=-4.050, p<0.001), Revised Children's Manifest Anxiety Score(t=-2.757, p<0.01), Rosenberg Self-Seteem Score(Z=-2.328, p<0.05) were significantly associated with the suicide ideation in North Korean Refugee Adolescents. In logistic regression analysis, only The Center for Epidemiologic Studies for Depression Score(p<0.005) expected the suicidal ideation. Conclusions : The management of depression would be helpful to reduce the suicide in North Korean Refugee Adolescents.

비선형 진동은 그간 많은 연구를 하여왔으나, 주로 1자유도계에 국한되었으며, 2자유도 이상의 계에서는 아직도 실용성 있는 연구결과는 극히 제한된 상태에 머물러 있다. 최근 약 30여년간 다자유도계의 비선형 normal mode진동은 산발적으로 연구되어 오다가 1966년 Rosenberg교수가 이를 종합 정리하엿으며, 그 이후에도 많은 연구가 계속되고 있다. 본 해설에서는 이 분야의 주요 연구결과를 소개하고 앞으로 다루어져야할 과제에 대하여 설명하고저 한다.

Hocking, Rao, Rosenberg and Levy and Walls and Weeks have given some results for the misspecification in univariate regression model. We give similar results for a multivariate regression model.
