The purpose of this paper is to examine the change of the times on the transmission rate of broadcast message. In order to find out the research results, I collected past recorded news tapes and selected 22 radio news out from era of Japanese Imperialism, 1950's, 1960's and contemporary age. Next I measured each announcer's reading rate, and compared change on news-reading rate between present and past approximately 50 years ago. The results of study with such procedures and methods are as follows : the average reporting rate of newscasters in each era is different. From these results, we can easily grasp diachronic change in the transmission rate of broadcast message. Namely, the results show us that present announcers read news faster than the group of past era of Japanese Imperialism by 68%.

Patent ductus arteriosus in adult is frequently complicated with aneurysm, calcification and pulmonary hypertension. Therefore, surgical treatment of patent ductus arteriosus in adult has some differences from that of infants and children. We have experienced 25 cases of adult patent ductus arteriosus from July 1983 to December 1994. Mean age of the patients was 26.6 years[16-59 years . There were 12 males and 13 females. Exertional dyspnea was the most frequent clinical manifestation. Pulmonary hypertension was present in eight patients. Ligation was done in 20 cases and surgery using cardiopulmonary bypass was done in 5 cases. There was one hospital death, which had a 5x5cm sized main pulmonary artery aneurysm and was operated under cardiopulmonary bypass. Recanalization occured in one patient who received Teflon-felt supported ligation. Although one case of recannalization after ligation was present, we believed the fact that ligation was safe and simple method of operation in adult patent ductus arteriosus without calcification and aneurysm.

The study area is filled up by alluvium which can be classified into lower and upper beds by the facies of deposits and their degree of weathering. The lower bed is not of marine but of fluvial. The upper bed is mainly composed of clay and silt or fine sand beds col-ored dark or dark gray which are of neritic or brackish yielding mollusca fossils. The oyster(Crassostrea ariakensis) obstained from the depth of 3m below the present sea level in the upper bed was dated at 4,100 110Y.B.P. and the veneridae(Meretrix lamarck) 1m height above the present delta plain in the old sand bar was dated at 1,700 85Y,B,P. It is therfore concluded that the study area a small kern col of terrestri-al basin prior to postglacial age had experienced the Holocene transgression. Consequently the study area is considered to have been progressively formed under neritic or brackish circumstance before 1,700Y.B.P.

In internationalization age, growth plan of a railway have to research with the opening of a train express and connection with a transcontinental railway. Especially, in the opening of a train express, the North Korea is located in an important place. So the North Korea must research for growth of railway of the South Korea. This study make an investigation the present condition of railway of the North Korea into a report, paper, article etc.. And then, it make a comparative study with a case study of Germany. Then, a policy object, have to be stand at the head in the opening of a train express, exhibited.

Schmidt hammer and ultra-sonic method are commonly used for crushed sand concrete compressive strength test in a construction field. At present, various of equations for prediction of strength are present, which have been used in a construction field. The purpose of this study is to evaluate the correlation between prediction strength by presentation equations and destructive strength to test specimen, and find out which is a suitable equation for the construction site, In this study, a strength test was carried out destructive test by means of core sampling and traditional test. Non-destructive test was conducted Schmidt hammer and ultra-sonic method, the experimental parameter were concrete age, curing condition, test method and strength level. It is demonstrated that the correlation behavior of crushed sand concrete strength in this study good due to the perform analysis of correlation between core, destructive strength and non-destructive strength.

The purpose of the present study was to investigate the relationship between spatial ability and sex-role orientation in children. For this purpose, 303 boys and 293 girls were selected randomly. Spatial ability was measured by Embedded Figures Test. Sex-Role orientation was measured by the Children's Personal Attributes Questionnaire (Spence, Helmreich & Stapp, 1975) which was translated into Korean. An item analysis was done. For the data analysis, a three-way analysis of variance and t-test were applied. The results of the present study showed that 1) spatial ability gradually improved between 10 and 14 years of age. 2) There were no significant differences between girls and boys in the performance on the spatial ability test. 3) Masculinity in girls was not significantly associated with high spatial ability. However, there was a tendency for the masculine girls in the direction of higher spatial scores than feminine girls and undifferentiated girls. 4) Femininity in boys was not significantly associated with high spatial ability. However, there was a tendency for the feminine boys in the direction of higher spatial scores than masculine boys and undifferentiated boys.

This research is the object to investigate these thing; how do teachers undertaking at the spot classrooms to recognize performance assessment and how do they decide to question and how go the present practiced state and what is the problem points in the present performance assessment. Additonal things of problem point like a research object are following; Lets look over recognition, actual situations and various problems for mathematics performance assessment of elementary school teachers. Concerning question papers, the problem largely lie in 4 regions, that is to say the recognition of performance assessment, the current state of affairs in practice, deciding questions and problems of putting theory into practices, of the 480 teachers-the object of our studies-about 380 returned our questionaire. However, as there were too many in the age range 30 to 40 are excluded 80, choosing 300 to us as data in our analysis.

Purpose: This study was designed to identify clinical competence and education needs of hospital nurses. Method: A questionnaire was used for data collection which was done form July 1 to July 30, 2005. The respondents were 165 staff nurses in a university hospital. The study instrument were clinical education need scale and Lee(2002)'s clinical competence scale. The data were analyzed using percentages, means, t-test, ANOVA with SPSS-WIN 10.0 program. Result: The results of this study are summarized as follows: The total mean score for clinical competence was 2.57 and education need was 3.30 on a 4 point scale. There was a significant difference in clinical competence according to individual factors of age, marital status, preceptorship experience, present ward, job satisfaction, and total clinical experience. also there was a significant difference in education needs according to preceptorship experience and present ward. Conclusions: Conducting a education needs and clinical competence assessment can provide valuable information that will plan education program and improve staff competence.

The first introduction of reformed Korean traditional cloth in was started in the age of civilization and until liberation from imperialism it was made a reformation in faculty from Korean traditional clothing. And by 1980s western style costume took lead but after Asian Game in 1986 and Seoul Olympic in 1988 Korean traditional beauty was added to costume and there were various attempt to produce truly reformed Korean traditional clothing. The present condition of reformed Korean traditional clothing in 1990s are like this : 1) Most of reformed Korean traditional clothing ships could not fractionalize customers. So it needs to subdivide and specialize customer and investment to improvement of design. 2) A large percentage of reformed Korean traditional clothing is ordinary dresses. So it should develop various sorts and color, design and textile and be in harmony with international trend. 3) Most of shops handled a coordinate goods like a bag and shoes. 4) In the investigation customers they wanted various colors, high quality in design , logical price and a periodical sale.
