In recent years, there are considerable debates on the theoretical approaches of industrial democracy in the academic world of indutrial sociology, but the level of debate is still low, ambiguous and complicated. For these reasons, this paper is Iargely concerned with theoretical Issues and aims at delineating and understanding the major strands in throretical debates in this area. To do this, sociological debates and Iinks of the business firms and industrial democracy to understand the possible meaning and implication of industrial democracy in business firms are given. Thus, the evolutionary perspectives in which workplace is seen as gradually unfolding alongside changes in the economic, political and social structure, Cyclical perspectives which sees a discontinuous process of advance and retreat, and Comparative-Cultural perspectives which focuses on the cultural, ideological and value patterns are discussed. At the concluding part of the paper, the theoretical approach into a comprehensive analytical framework is emphasized for establishing the schemes for industrial democracy and understanding the theoretical and analytical core of this area of study.
항공사의 웹컨텐츠 품질에 있어서 구성개념의 타당성 연구
장준호 東亞大學校 大學院 2005 大學院論文集 Vol.30 No.-
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.
J.C. Hubbard 理論의 再吟味 : 消費上昇 理論을 中心으로 Chiefly on Theory of Consumption Increment
張晙昊 西原大學校 1976 西原大學 論文集 Vol.5 No.-
This study is to search for the development directions and accurate position of fundamental problems in modern consumption theory in an attempt to understand and observe Hubbard's theory. This paper is systematized as follows; The first chapter deals with Introduction. The second chapter explains Various Theories of Past Consumption function. Absolute Income Hypothesis Relative Income Hypothesis Liquit Assets Hypothesis Permanent Income Hypothesis The Third chapter points Core of Hubbard's Theory a : Marginal propensity to consume which bring forth real Income Increment b : Marginal propensity to consume which bring forth Employment. Y : Income Increment which is expenditured. Consumption rising is a Y and it induces additional income bY. In case of a>b, Consumption is not only increased but brings about higher income level and it gives impetus to the rising of average propensity to consume. Put it in another way, consumption function in Short run moves upward due to productivity improvement. The last chapter suggests Some Problems and Review on Hubbard's Theory. It is true that Hubbard's Consumption Function in the short run moves upward due to productivity improvement so long as the Stability of kuznets' average propensity to consume in the long run is justified, but his theory is not fitted for the universal validity but only recognized under the special case and limited conditions.
정지 영상 화질 평가와 Contourlet 변환을 이용한 압축 방법에 관한 연구

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.
