The purpose of this study is to analyze the 'Pleasant Life' textbook in the elementary school focused on the perspective of ethnocentrism and cultural relativism. The first- and second-grade textbook 'Pleasant Life' of the revised 2007 national curriculum was made to serve build up sound body and mind through activities and play together with different products and life culture which is associated with multicultural education. But in the global world that is changing to the multicultural area, the textbook 'Pleasant Life' has a tendency to not to be satisfied this current needs. The analysis criterion is made up six elements: understanding culture, self-identify, human equality, conquest of prejudice and collaboration. The results of analysis on contents related to the multicultural education in the elementary 'Pleasant Life' textbook for the 1st and 2nd grade are follows. The first, in the plenty of images and pictures, there are not diverse races in the textbook. Yellow race naturally command an overwhelming majority in the textbook images and pictures. Second, the 'Pleasant Life' has a few multicultural contents and if teacher would not have will for teaching multicultural contents, he can't teach multicultural education. Third, 'Pleasant Life' textbook has overmuch ethnocentrism contents which is expressed traditional play and folk songs. These contents lead to exclusiveness for other culture to students. In conclusion, it is needed to grow concerns for multicultural education and the national curriculum should offer precise guidelines on the direction and standards of multicultural education.

The aim of this study was to estimate genetic parameters and annual trends on the racing performance of Thoroughbred horses by a statistical analysis of the resulting records. We used the racing results of 245,979 observations for 13,458 horses recorded in 19 years of race held at Seoul and Busan racing tracks, provided by Korea Racing Authority. After a careful adjustment of some variables such as racing times, jockey and trainer numbers and the average prize a horse won, we selected significant factors that explain the result of racing records of a horse by stepwise AIC and BIC methods. The estimated heritability and repeatability were 0.322 and 0.332, respectively. The average of annual phenotypic and genetic improvement was -0.166 seconds and -0.161 seconds, respectively. Based on the statistical approach, we established reasonable animal model of well-set variables, which is important in the study on estimating performance of racing horses.
