This paper examines the validity of Web Contents Quality in airlines. The Second-order confirmatory factor analysis(CFA) were performed to assess the convergent and discriminant validity of five dimensions of web contents quality and their contributions to an overall construct of web contents quality. The results provide evidence for the construct validity of web contents quality. the limitations of the study were explored, and suggestions were given for further research.

The wavelet transform was adopted as the transform for JPEG2000. However, wavelet has weakness about smoothness along the contours and limited directional information. So we use to other transform, called contourlet transform in compression. Objective quality assessment methods currently used Peak signal to noise Ratio(PSNR). But that is not very well matched to perceived visual quality. So new image quality assessment is required. In this paper, we propose a new method for image compression based on the contourlet transform, which has been recently introduced. In addition we evaluated compression image quality using PSNR and SSIM. Finally contourlet transform has a good result about images with smooth contours and SSIM is good method for image evaluation compared to PSNR.

Korea's modernization, begun in the early sixties, has recorded remarkable progress in improving the nation's economy in the course of implementing successive long-term economic development plan. The aim of this article is to analysis how forein trade progress has affected the industrial structure and nation's economy in the economic development of Korea during the period of 1953~1973. In analyzing the relation of foreign trade progress and nation's growth, the method of various correlation coefficients mearsured by regression equation is used and the period of analysis was divided into two major stages and three minor stages in the light of economic growth of korea : the stage of maintenance economy(1953~1965) and development economy(1966~1973) In a few words, foreign trade of korea in the period of stagnatory economy(1953~1959) had almost not affected the nation's industrisal structure and korean trade in the period searching for economic development(1960~1965) had converted primitive nature-intensive trade economy to the labour-intensive trade economy. The conclusion is that foreign trade of korea has achieved notable improvement in the industrial structure in the period of development economy(1966~1973) and leading industry, manufactures among the whole economy which have been developted by rapid trade expansion has not only made the whole economy of korea into the labour-intensive light industry, but also the deep dependent economy to international economy. Therefore, the emphasis of all economic policy must be on the establishment of primary industry, substitute industry for resources and heavy & chemical industry to cope with many new challenges in our path toward economic development of korea. This article is systematized as follows ; The first chapter presents introduction The second chapter points out Industrial Structure and Economic Development 1. General Rules of Development in the Industrial Structure 2. Fluctuations and Present Stage of Industrial Structure 3. Manufactures and Leading Industry The third chapter deals with Foreign Trade Progress and Its Fluctuations 1. Period of Maintenance Economy 2. Period of Development Economy 1) Fluctuations of Foreign Export Trade 2) Fluctuations of Import Trade The Fourth suggests Foreign Trade Progress and Our Economy 1. Correlation of Foreign Trade and Economic Growth 2. Leading Industry and Foreign Loan 3. Trade Economy regulated by Foreign Dependence The last chapter treats Summary and Conclusion

本稿는 日本, 東京都 世田谷區 太子堂地區 烏山川(가라수야마가와) 綠道整備事業을 분석 평가하므로서 본격적인 지방자치시대를 맞이하여 우리나라의 都市再整備事業을 수행함에 있어 당해지구 주민의 內發的 能動的 參與의 緊要性을 인식시키는데 그 목적이 있다. 또한 體系的 /效率的인 도시환경정비사업을 추진함에 있어 본 사례연구가 하나의 方向舵가 되기를 바라는 바 본 연구 결과 다음과 같은 결론이 도출되었다. 첫째, 綠道整備事業을 추진함에 있어 當該地區 住民이 주체적으로 참여함으로서 密集住宅市街地의 現狀認識은 물론 地區環境整備課題는 주민측의 自力更新이 긴요함을 파악하였다. 둘째, 도시정비사업을 추진함에 있어 주민측의 지역 에고이즘이 露呈되었으나 행정측의 합리적 객관적 접근 여하에 따라 長期基本構想을 貫徹시킬 수 있다. 셋째, 녹도정비사업의 波及效果로는 당해지구의 物理的環境 改善事例에 의해 周邊 및 隣接地域 주민의 地區環境整備에로의 지대한 관심의 誘發과 내발적 참여의 가속화등 직간접적인 파급효과가 있음이 檢證되었다. The purpose of this paper is to evalute of citizen paritcipation planning as seen in the KARASUYAMAGAWA Green Walkways improvement porject in the TAISHIDO district of SETAGAYA-Ku, TOKYO, JAPAN. The analysis of this district the following conclusions have been drawn. First, the improvement of densely built up areas is in progress with help of the introduction of the Green Walkways project. Second, KARASUYAMAGAWA Green Walkways projects has been successful not only as a visible symbol of the community but also an excellent example of citizen involvement.
