An attempt has been made here to study the propagation of SH-type surface waves in an elastic medium, which is initially stressed and heterogeneous and has a point source inside the medium. The upper portion of the composite medium is a sandy layer. It is situated on an initially stressed heterogeneous half-space, whose density, rigidity and internal friction are function of depth. The analysis has been carried out by using Fourier transform and Green's function approach. The phase velocity has been investigated for several particular situations. It has been shown that the results of the study agree with those the case of Love wave propagation in a homogeneous medium in the absence of the sandy layer, when the initial stress is absent. In order to illustrate the validity of the analysis presented here, the derived analytical expression has been computed numerically, by considering an illustrative example and the variances of the concerned physical variables have been presented graphically. It is observed that the velocity of shear wave is amply influenced by the initial stress and heterogeneity parameters and the presence of the sandy layer. The study has an important bearing on investigations of different problems in the earth's interior and also in seismological studies.

Purpose : The purpose of this study was 1) to classify university student's attitudes toward sex, 2) to confirm the effects of sexuality course on sex-role stereotypes and sexual attitude in university student s. Method : The subjects in this study were 212 K university students in Kangwon Province between 3/7/2001 $\sim$ 6/13/2001. The instruments used for this study were the general characteristics, sexual attitude and sex-role stereotypes. The data was analyzed by frequency, percentage, mean, standard deviation, paired t-test, ANOVA, Pearson correlation coefficients, Factor analysis and Cronbach's $\alpha$ using the SPSS program. Result : 1. University students' attitude toward sex are divided into three types. Type I are called open mined : 16, 33, 28, 10, 18, 2, 30, 25, 26, 27, 22, 19, 29, 21, 9, 5 items. Type II are supporters of virginal purity : 8, 6, 31, 17, 14, 33 items. Type III express love through sexual intercourse : 20, 24, 7, 3, 15, 32 items. 2. There was a significant difference in the appearance and occupational characteristics of sex-role stereotypes before and after the sexuality course (t=2.562, p<.05). 3. In Type III, there was a significant difference in sexual attitude before and after the sexuality course (t=3.576, p<.0001). 4. The data showed the relationships between type III of sexual attitude and sex-role stereotypes (r=-.3 15, p<.0001). 5. Sex-role stereotypes according to the demographic characteristics before sexuality course were significantly different by age, gender, experience of military service, experience of sex edu cat ion an d experience of sexual intercourse. Sex-role stereotypes according to the demographic characteristics after sexuality course were significantly different by gender and experience of sexual intercourse. 6. Sexual attitude according to the demographic characteristics before sexuality course were significantly different by maj or (type I), age, grade, experience of military service and experience of sexual intercourse (type II), age, grade, gender, experience of military service, experience of sex education and experience of sexual intercourse. Sexual attitude according to the demographic characteristics after sexuality course were significantly different by religion and major(type I), age and grade(type II), age, grade, gender, religion and experience of sexual intercourse.

Free axisymmetric vibrations of layered cylindrical shells of variable thickness are studied using spline function approximation techniques. Three different types of thickness variations are considered namely linear, exponential and sinusoidal. The equations of axisymmetric motion of layered cylindrical shells, on the longitudinal and transverse displacement components are obtained using Love's first approximation theory. A system of coupled differential equations on displacement functions are obtained by assuming the displacements in a separable form. Then the displacements are approximated using Bickley-spline approximation. The vibrations of two-layered cylindrical shells, made up of several types of layered materials and different boundary conditions are considered. Parametric studies have been made on the variation of frequency parameter with respect to the relative layer thickness, length ratio and type of thickness variation parameter.

The purpose of this study were to collect the data for searching the better day care service programs among the employed mothers of the urban low income class. The Subject were 280 low income class employed mothers with the child under age of six, who lived at the Gwang-ju City. The frequency, percentage, and χ2test were calculated for the analysis of the collected data. The Results were as follows ; 1) Most of the urban low income class employed mothers needed day care facilities. 2) Urban low income class employed mothers preferred a center-based day care program to any other type of day care program. They also preferred the whole-day day care service 8 A.M. to 6 pp.M. rather than the half-day care service. Mothers with the child at the age of 3 to 6 years mostly wanted day care program service. 3) They expected the government or their companies to support considerable amount of day care service fee. Most of mothers emphasized the child's every day life's and love for the children was most preferred. Mothers also wanted 14-16 years for teacher's education career.

This study has evaluated the weld metal solidification cracking behavior of several Ni base superalloys (Incoloy 825, Inconel 718 and Inconel 600). Austenitic stainless steels(304, 310S) were also included for comparison. In addition, a possible mechanism of solidification cracking in the fusion zone was suggested based on the extensive microstructural examinations with SEM, EDAX, TEM, SADP and AEM. The solidification cracking resistance of Ni base superalloys was found to be far inferior to that of austenitic stainless steels. The solidification cracking of Incoloy 825 and Inconel 718 was believel to be closely related with the Laves-austenite (Ti rich in 825 and Nb rich in 718) and MC-austenite eutectic phases formed along the grain boundaries during solidification. Cracking in Inconel 600 was always found along the grain boundaries which were enriched with Ti and P. Further, solidifidcation cracking resistance was dependent not only upon the type of love melting phases but also on the amount of the phases along the solidification grain boundaries.

Objective : The purpose of this study was to verify the differences of expressed character strengths graded as per the Korean Strength Scale, based on the type of work. Methods : A total of 2,444 conglomerate workers were classified into two groups: 1,356 office workers and 1,088 production workers. The subjects were examined through a web or mobile application based on the Korean Strength Scale. The Korean Strength Scale consists of a total of four top entries and 25 sub-items with appropriate validity. Results : The difference in the average score of sum of character strengths between the two groups was not significant. In the office worker group, character strengths such as love of learning, creativity, perspective, curiosity, facilitation, judgment and faith had significantly high scores. On the other hands, modesty, hope, gratitude, sincerity, magnanimity and self-regulation were high in the production worker group. The results remained unchanged in additional analysis of covariants as sex, age and education level, except for self-regulation and faith. Conclusion : Our results suggest significant differences in the character strengths between the two types of work; however, the average of sum of character strength score remains unchanged. These results may help to understand differences between work environments and thus help to establish a positive foundation.

The purpose of this study is to clarify the adaptation of beauty of traditional dress depicted contemporary Korean fashion design. For this purpose, the external form and the internal meaning based on 'the double roots' proposed by W$\ddot{o}$lfflin were analyzed in Korean traditional dress. Documentary studies and objective studies were done with descriptive and content analytic methods. And homospatial process was devised in order to develop the traditional identity in contemporary fashion design. The results were as follows: 1. As the external form, H. O. A silhouette, chogori, ch'ima, paji, and po concerning internal type, kaftan, flat form related to structured type were represented. Traditional color sense were love of white, contrasting as well as analogous color harmony shown often in nature phenomena, and temperate achromatic color harmony. Texture were characterized as rough and coarse expressing vividness, fine and smooth expressing delicateness and tenderness. As the internal meaning, the beauty of purity related to nature, tragedy, and symbolism were represented. 2. Since 1980's. Korean fashion designers frequently applied unstructural kaftan form and H silhouette to Korean fashion design, and sought natural and pliable line in whole dress. Use of white and achromatic color harmony as well as use of linnen were prominent. Designers' aesthetic consciousness was pursuit of the beauty of nature. Representative designers who concentrated on expressing traditional beauty were Lee Shinwoo, Sul Yoonhyung, Jin Taiok and others. 3. A homospatial process could be a method in the creative design which enables to express Korean identity in fashion design, and could suggest ideas of new designs full of Korean identity by superimposed and fused imaginery.
