Two-Lane Highway of Korea is important, Because it has the largeest portion of all roads of Korea. But it has only one lane for one direction. So, If Delays are happened by low-speed vehicles, high-speed vehicles should over-take through the other side of the road. This over-takings can generate the high possibility of traffic accidents and the severity of traffic accidents by over-takings is very high. Because it generates a head-on collision. But the level of Service that indicates the operation states of Two-Lane Highway is defined as a conception that explains the operation conditions of traffic safety etc. Whencalculating the Level of service. It is considered by only delays. So, in this paper, first, this author wants to present the calculation of delay-time by Total-Delay Rate. Second, by multiplying this delay-time by the costs of delays wants to present the method of calulates the total delay costs. Third, to consider the traffic accidents, After predicting the number of traffic accidents, As multipling this by the average of costs of traffic accidents. want to present the method to calculate Total traffic accidents costs.

It is necessary to discover Korea's diverse traditional culture and publicize it to the world to continue the Korean Wave and develop it in a more positive direction. The present study proposes methods for publicizing little-known 'traditional Korean ceramic tableware' by focusing on Hansik, which is the most frequently published in the British Oxford Dictionary among Korean traditional cultures and can best represent Korean food. To this end, the present study measured cultural recipients' emotions regarding traditional Korean ceramic tableware to derive the 'representative emotions felt regarding traditional Korean ceramic tableware' as a method to reflect it in the design. First, the Delphi Technique was carried out based on 182 emotional vocabulary items collected from existing studies to create 33 groups of emotional vocabularies with similar concepts. In addition, among the emotional vocabularies included in each of the 33 groups, those of overlapping concepts were regrouped based on the characteristics of traditional Korean ceramic tableware, and the most appropriate emotional vocabularies were extracted and reduced to 75. A survey was carried out with 135 cultural recipients experienced with traditional Korean ceramic tableware to derive 32 representative emotions felt regarding traditional Korean ceramic tableware. Finally, from the results of a factor analysis of 32 representative emotions, this study classified vocabulary into six emotion categories including 'aesthetic, pleasure, freshness, ownership, satisfaction, and comfort'. The six emotion categories and 32 representative emotions derived from this study's results can be utilized to measure emotional levels felt by cultural recipients while using traditional Korean ceramic tableware.

The purpose of this study was to acquire the better and more correct information on the school uniforms with which middle or high school students may be satisfied. We investigated clothing interest, school uniform satisfaction, school uniform modification behavior and the relationship anions those factors. The data were collected from 472 questionnaires of middle and high school students who lived in Gyeonggi-do and analyzed statistically. We found that adolescents felt a great interest in appearance, fashion, brand orientation of clothing, and they spent most of personal expenses in buying clothes. However, the extent of adolescents' satisfaction on school uniform was low. Especially, the satisfaction on status symbolism, fashion, washing & management, body comfort and economical efficiency of school uniform was found low. Three hundred fifty three students (74.8%) agreed to modify the school uniform for personality and in chase of fashion. Two hundred eighty four students (58.1%) needed partially and variously modified school uniform, and these modifications showed a tendency of tightness to the body. We also found that the higher adolescents' clothing interests in appearance, conformity, modesty and brand orientation were. the more satisfied adolescents were with the status symbolism and the washing & management of school uniform and the more affected the school uniform modification behaviors of students were. There were. however. no significant difference between the extent of school uniform satisfaction and the school uniform modification behavior, Another research of school uniform will be necessary in order to reduce the discrepancy between clothing needs for representing the appearance, personality and fashion in the present adolescents and those for representing the worthy and modest images of a student and pursuing the economic value through school uniform in the older generation. We suggest that students should consider these results when they choose school uniform and furthermore both the person in charge of schools and school uniform makers should refer to those when they design and make school uniform.
