The purpose of the study w3s to investigate the consumption pattern of the Korean traditional foods of the elementary schoolchildren living in urban and rural area. For the investigation, 373 fifth-grade elementary schoolchildren in Incheon and Gangwhado were surveyed by a questionnaire and the data were analyzed by the SPSS 10.0 program. As for the frequency to take the Korean traditional foods, bab and kimchi are taken almost everyday, and gug, jjigae, jorim, gui, namul are taken frequently. And juk, jeongol, jeon, sanjeog, jutgal, hangwa and umryo were shown to be taken occasionally. There were statistical differences in the frequencies of the Korean traditional food consumption by the residence and the gender. The students in urban area take hinbab, jabgokbab, hobakjuk deonjanggug, sangsunjorim, jangiorim more frequently than the students in rural area. The students in rural area take mandu, kuksoo, yeongunjorim and kongiorim more frequently than the students in urban area Female students take sangsunjorim, jangiorim, sangsungui, bulgogi, sangsunjeon, hobakjeon, sukchae, jutgal and oiji more frequently than male students. Most of the schoolchildren answered that in the future they would like to take the traditional foods more frequently than now. There was statistical difference by the gender. As for the food such as bibimbab, gug, jjigae, jeon, namul and jang-aji, female students responded to take more frequently than male students. The 39.1% of them responded that the taste is the point to be most improved in the future. But there was no statistical difference by gender and the residence In order to make the taste of traditional food more attractive to modem people, the 37.8% of them replied it does not need to change the traditional preparation method. However, similar percentage of the schoolchildren(35.7%) answered it is needed to change partly the traditional preparation method. As for the effect of traditional foods on health, the 68.4% of schoolchildren thought that the our traditional foods are healthier than western foods.

Online models predicting roll force and forward slip of roughing mill was developed using nondimensional parameters. Using the effective inlet thickness, roll force model take into account the effect of inlet dog-bone shape of slab which take places after width reduction through edger rolling in roughing mill. The prediction accuracy of the proposed model is examined through comparison with measurements.

This article discusses the teaching of listening and reading skills through enhancing the awareness of pronunciation. First, it examines the problems which take place in listening comprehension, and seeks the ways in which we can teach the skill rather than simply practise it. The approaches proposed are based on micro-listening exercises which practise individual subskills of listening, especially by using the cloze test and tracking. The issue of using authentic materials is then examined for teaching recognition of the features of natural speech. Finally, it is argued that classroom activities need to take account of the true nature of real-life L2 listening.

Feedback herding strategy in stock market means considering other investor's strategy as a basis of market forecasting of next term. Generally, individual investors use that strategy which mimics the strategy of institutional investors. When it is used in stock market, both kind of investors, preceders and followers, can take the higher average of rate of return to normal market in which no feedback herding strategy is not use, the more investors take part in. And variance of return, the risk of investment, are same to both group.

In business survey. cut off sampling is usual. The contribution from cut off part of the population is at least small in comparison with the remaining population. In this study. the population have been separated as three stratum, cut-off. take-some, take-all, and we will estimate cut-off part.

Subsequently in Korea product liability has been introduced. The position of consumers for defective products have been disadvantageous. Defective products should be broght under the law. Then, while consumers would be largely protected, a producer would take the heavy responsibility by law, Therefore, a producer would not be able to take countermeasures for product liability. Object of this paper to investigate and analyze the actual state of management for product liability in advanced countries, and to join it with our quality management system.

Coloring admixture is used for take color inside and outside of mortar and concrete, differently form pigment and spray paint take color limited surface. In our country, Using the coloring admixture is very slight and regulation is not yet about it. But that is expected the increase with raising the standard of living. Especially it is used to civil structure like dam and seawall for the environment harmony. Then we observe, in this experiment, the effect of coloring admixture on the material properties of color concrete and propose the suitable mix-proportion of color concrete.

Let $F$ be a set of distributions on R with the topology of weak convergence, and let $A$ be the $\sigma$-field generated by the open sets. We denote by $F_1^\infty$ the space consisting of all infinite sequence $(F_1, F_2, \cdots), F_n \in F and R_1^\infty$ the space consisting of all infinite sequences $(x_1, x_2, \cdots)$ of real numbers. Take the $\sigma$-field $F_1^\infty$ to be the smallest $\sigma$-field of subsets of $F_1^\infty$ containing all finite-dimensional rectangles and take $B_1^\infty$ to be the Borel $\sigma$-field $R_1^\infty$.
