Component-based software development [CBSD] is a new paradigm of recent software development. CBSD was started from reuse of software and study on software component technique. In order to improve produce and quality of software development, there is study on reuse of components lively and how to develop, share, and manage components effectively. In this study, I would like to suggest a method that is able to simply test a new application system by developing systems developed individually into components, registering them, and combining them.

The objective of the study is to create color plan for company D based on color images of the Bloomsbury Group paintings, which is an art institute based in Bloomsbury, London, a hometown of the company, to renew the traditional brand image of the company by blending fashion and art. This study analyzed 'D's previous F/W Color planning from 2003 to 2007 through NCS to understand characteristics of company D's color planning. It considered company D's color renewal concept by looking into Bloomsbury Group's backgrounds and pieces. Based on 2008-2009 F/W color trend and the analysis result, the study suggests a color plan with reference to a case study of the company D, for which I work as a colorist. The color renewal of the company D for 2008-2009 F/W season was categorized into theme I. Bloomsbury and theme II. Charleston for planning. The following table summarizes the result of 2008-2009 F/W season color plan with focus on development of new check and print patterns. The significance of the study can be found in that it advanced beyond the color planning stage to be applied to the actual renewal. Through a renewal of an existing brand, a fashion brand can be revitalized to have distinguished competitiveness.

This paper is. a study on relation between road traffic noise(RTN) and sound power level(PWL). At present, many experimental formulae and prediction formulae are used for prediction of RTN. But these formulae are difficult to appiy to the metropolitan area because these formulae are inaccurate in the different condition from reference condition. This paper calculate RTN and PWL of each prediction formula, choose the best one and make a noise map of the subject area. Procedure is as follows. First, calculate $L_{eq}$ of RTN using experimental formulae and prediction formulae. Second, calculate PWL using $L_{eq}$ of RTN and distance attenuation for point source at semi-free field. Third, choose the most accurate formula. And finally, make a noise map of the subject area at present and future. The result using noise map will be able to apply to application field. Noise mapping tool used on this paper is Raynoise program using Ray Tracing Method(RTM), Mirror Image Source Method(MISM) and Hybrid Method(HM).

본 연구에서는 KOMPSAT-3A 위성영상과 세분류 토지피복지도를 이용한 환경가치등급 분류를 수행하여 국토환경성평가지도의 주기적인 갱신 및 제작 가능성을 제시하였다. 환경성평가지도(ECVAM: Environmental Conservation Value Assessment Map)는 62개의 법제적 평가항목과 8개의 환경·생태적 평가항목을 기준으로 국토의 환경적 가치를 5단계의 등급으로 평가한 지도이며, 1:25000과 1:5000의 두 가지 축척으로 제공되고 있다. 하지만 1:5000 축척의 환경성평가지도는 참조자료의 부재 및 상이한 제작년도 등 다양한 제약조건으로 인해 1년 단위의 느린 갱신주기로 제작되고 있다. 이에 본 연구에서는 KOMPSAT-3A 위성영상과 광학지수(SI: Spectral Indices) 그리고 세분류 토지피복지도를 활용하여 딥러닝 기법 중 하나인 CNN (Convolutional Neural Network)을 기반으로 정확하고 최신정보가 반영된 1:5000 환경성평가지도를 구축 가능성을 확인하고자 한다. 실험 결과, 본 연구에서 제시한 방법으로 제작한 환경성평가지도의 정확도는 각각 87.25%, 85.88%로 산출되었다. 연구의 결과를 통하여 위성영상, 광학지수 그리고 토지피복분류를 활용한 환경성평가지도의 구축 가능성을 확인할 수 있었다.
