The Kolmogorov-Smirnov, Crame´er-von Mises, and Anderson-Darling Statistics are considered for testing the goodness of fit of the two-parameter Weibull distrubution. The statistics for testing the goodness of fit a completely specified distribution are modified by replacing the Weibull parameters by their maximum likelihood estimates. Also considerde are two tests due to Mann, Scheuer, and Fertig(1973), and to Smith and Bain(1976). Tables of critical values are represented for the Kolmogorov-Smirnov, Crame´er-von Mises, and Anderson-Darling statistics. The results of a power study are represented comparing all five tests.

This study was attempted to investigate the relationship between clothing & appearance self image and self concept of college women. The following null hypotheses was established for this study. 1. There are no significant relationships among subscales of the clothing & appearance self image measure. 2. There is no significant relationship between the self concept disparity and the clothing & appearance self image disparity. 3. There is no significant relationship between the self concept disparity and the clothing & appearance real self image. Clothing & appearance self image of college women was also invetigated. Measure selected for this study consisted of "Index of Adjustment and Values Scale" (Edmiston, 1960) and "Clothing & Appearance Image Measure". (Deemer, 1967). Data were obtained from 380 college women. For statistical analyses, the Pearson's Product-moment correlation coefficients, One-way repeated measure ANOVA, and Newman-Keuls tests were used. The levels of significant were established at .05and .01. The Results were as follows; 1. There were highly signific-ant relationships among clothing & appearance self image measure subscales except economic-aesthetic, physical comfort-social dominance in the real self image and economic-social dominance in the ideal self image. 2. There was significant positive relationship between the self concept disparity and the clothing & appearance self image disparity. 3. There were partially significant negative relationships between the self concept disparity and the clothing & appearance real self image. The significant variables were aesthetic and social dominance. 4. In the clothing & appearance real·ideal self image, college women scored highest in care and lowest in social dominance. In the clothing & appearance self image disparity, they had the highest score in aesthe tic and lowest score in social empathy.

The demonstration that behavioral states and CNS processes are associated with immune function suggests that there may be a relationship between anxiety and the immune system. Stress and immunity have been studied extensively, but there have been relatively few studies of anxiety and immunity. This study was done to study immune function in patients with anxiety disorder focusing on lymphocyte subsets. The subjects were 15 patient with anxiety disorder (5 male. 10 female). 6 with generalized anxiety disorder, 4 with panic disorder. 2 with obsessive compulsive disorder. 2 with post traumatic stress disorder and 1 with phobic disorder diagnosed by three psychiatrists according to DSM-III-R criteria. Their average age was 31±11.4 years. They were admitted to Department of Neuropshcyiatry. Seoul Paik Hospital. from December 1988 to February 1991. The control group were 20 normal healthy adults and 15 hospitalized surgical patients. We measured numbers and ratio of T cell subsets(including helper-T cells and suppressor-T cells) as well as B cells and total lymphocyte counts in all group. The results were as follows : 1) There were significant differences among patients with anxiety disorder, surgical patients and normal control group in the percentage of T3, T4, B, and R4/T8 ratio, but no significant differences in number of total lymphocyte. T lymphocyte and percentage of T4. 2) In the each significant group of T3, T4, T4/T8 ratio and B % ; i) The percentage T8 in patients with anxiety disorder decreased(p<.05) compared with the normal control and the T4/T8 ratio increased(p<.05). The percentage of T3 was not significantly different. ii) The percentage of B lymphocyte in anxiety disorder increased(p<.01) compared with the normal control. iii) There was statistically significant difference between surgical patients and normal control group. Statistically, surgical patients were nearly consistent with anxiety disorder group. 3) In conclusion, there are statistically significant changes in the celluar and humoral lymphocyte immune function in patients with anxiety disorder, but further evaluation and more studies should be done to gain further information.

유방암과 섬유선종의 방사선학적 소견 : 유방 단순촬영술과 유방 초음파검사 소견의 비교 연구 Studies on mammographic and ultrasonographic findings evaluation

Purpose : To evaluate the utility of mammography and ultrasonography in study of morphologic differential diagnosis between malignant and benign mass. Materials and Methods : Average age of patients with breast cancer was 48.4 year-old, and that of fibroadenoma was 29.4 year-old. The equipments used for examination were MF-159 high frequency mammography(Bennet Co.) and Acoustic image 5200S. We evaluated mammographic findings about breast parenchymal pattern, calcification, margin and size of the mass associated tumor nature, and ultrasonographic findings about shape, height and width, internal homogenicity and echo pattern, wall contour, boundary echo, and posterior shadow in breast mass. Thirty-seven of mammographic findings and 34 cases of ultrasonogreaphic findings in pathologically proven breast cancer and 34 case of mammographic findings and 71 cases of ultrasonographic findings in breast fibroadenoma were reviewed retrospectively. Results : In mammographic study, the parenchymal patterns of breast cancer according to Wolfe classification were NI(16.2%), PI(24.3%), P@(37.8%), and DY(21.6%) and those in fibroadenoma were NI(3.1%), Pl(11.7%), P2(35.2%),and DY(50%). Mammographic findings about presence of calcification were as follows; only calcification(16.2%), only mass(51.3%), and mass with calcification(32.5%) in breast cancer, and only mass(91.2%), mass with calcification(8.8%) in fibroadenoma. The features of mass margins were classified as ill-defined margin(45.9%), well-defined(5.4%), and well-defined with partial spiculation(48.6%) in breast cancer and ill-defined(20.5%), well-defined(73.5%), and well-defined with partial spiculation(5.8%) in fibroadenoma. The mass were grouped by size; 1-2cm(37.8%), 2-4cm(45.9%), and 4-6cm(16.3%) in breast cancer and 1-2cm(79.4%), 2-4cm(17.6%), and 4-6cm (3.0%) in fibroadenoma. On ultrasonographic study, the shape of masses in breast cancer were lobulated(82.3%),oval(14.7%), and round(3.0%),and those in fibroadenoma were lobulated(14.0%), oval(57.7%), and round(18.3%). The cases that the height was longer than width were 32.3% in breast cancer and 0% in fibroadenoma. The findings about homogenecity and echo patterns were as follows; hypoechoic(52.9%) and mixed(47.1%) in breast cancer and hypoechoic(2.8%), hypoechoic(63.4%), and mixed(33.8%) in fibroadenoma. The margin of masses were smooth in 85.9% of fibroadenoma, and irregular in 73.6% of breast cancer. The boundary echoes of masses and decreased posterior echo shadow were seen only in 61.8% and 55.9% of breast cancer, respectively. Conclusion: The margin and calcifications are more clearly delineated on mammography but breast cancer and fibroadenoma, both are more commonly developed in dense parenchymal pattern(P2+DY),and there findings are easily obscured in mammography. So ultrasoography is very useful in these masses evaluation, especially amoung young patients.

Multivariate EWMA Charts for Simultaneously Monitoring both Means and Variances

Cho, Gyo Young,Chang, Duk Joon The Korean Statistical Society 1997 Communications for statistical applications and me Vol.4 No.3

Multivariate control statistics to simultaneously monitor both means and variances for several quality variables under multivariate normal process are proposed. Performances of the proposed multivariate charts are evaluated in terms of average run length(ARL). Multivariate Shewhart chart is also proposed to compare the performances of multivariate exponentially weighted moving average(EWMA) charts. A numerical comparison shows that multivariate EWMA charts are more efficient than multivariate Shewhart chart for small and moderate shifts and multivariate EWMA scheme based on accumulate-combine approach is more efficient than corresponding multivariate EWMA chart based on combine-accumulate approach.
