The digitalization of the fashion industry refers to 'the reception of the digital environment by the industry.'Re paper presented 3 conceptual categories of 'technological environment','information environment'and 'business environment'concerning the scope of digitalization, including from the introduction and use of new technical media to new ways of thinking following the paradigm changes. And it demonstratively analyzed digitalization factors and digitalization level of fashion businesses related to the factors by 7 fashion categories. The analytic result and its suggestions are as follows. First, the five digitalization factor of the fashion industry are defined : manufacturing Process automation, computer systemization, information networking, e-business, and small batch production. Second the digitalization degree of fashion firms decreases in the order of information networking, small batch Production, manufacturing Process automation, computer systemization, and e-business, with information networking on the top and e-business, recent focal point of interest, at the bottom. Third, as for the digitalization of each clothing category, men's formal dress and unisex display the highest level of the general digitalization.

최근 인터넷과 모바일 통신의 발전으로 인해 전자 서명을 이용한 전자 상거래(M-Commerce)가 널리 사용되고 있다. 모바일 환경은 유선 환경에 비해 단말기의 하드웨어와 네트워크가 취약하다. 따라서 효율적인 시스템 구축을 위해서는 전자 문서의 처리, 전자 서명 생성, 모바일 네트워크 대역폭이 성능에 미치는 영향에 대한 체계적인 분석이 요구된다. 본 논문에서는 이를 위해 전자 계약 시스템을 모델로 하여 XML을 기반으로 하는 전자 계약서와 RSA 전자 서명 알고리즘을 사용한 테스트 시스템을 구축하였다. 그리고 전자 서명 서비스의 수행 시간에 영향을 주는 요소를 분석한 후, 현재 상용화되고 있는 Compaq iPAQ 3850 단말기와 CDMA 2000 1x 네트워크를 이용하여 모바일 전자 서명 시스템의 성능을 체계적으로 분석하였다.

정보기술의 혁신과 네트워킹 기술의 발달에 따라 디지털복제, 디지털전송이 급속하게 증가하고 있다. 그러나 아날로그환경에서와 마찬가지로 디지털환경에서도 공공의 이익과 문화발전을 위하여 저작권을 제한하는 것은 불가피하다. 본 연구는 첫째, 공정사용을 위한 저작권 제한의 국제적인 동향과 미국 일본 등의 입법례를 살펴보았다. 둘째, 최근 국제적으로 쟁점이 되고 있는 RAM 저장과 화면현시와 관련된 디지털복제의 문제를 검토하였다. 셋째. 네트워크환경에서의 사적 복제, 도서관 등에서의 복제, 학교교육목적의 복제에 관련하여 공정사용 법리를 적용할 시 제기되는 문제점을 구체적으로 분석하였다. 그 결과, 아날로그환경을 염두에 두고 제정된 저작권 제한의 문제점들을 해결하기 위해서는 저작권법이 개정되어야 함이 드러났다. 끝으로 본 연구는 디지털 사적 복제를 통제하기 위한 제도적 장치로서 '저작권집중관리제로 의 활성화 방안과 '사적복제보상금제도' 의 방안을 제시하였다

디지털 콘텐츠 컴퓨팅 환경에서 서비스를 제공하는 서버시스템의 레지스터, 캐시메모리, 네트워크 정보 등의 휘발성 정보는 침해사고 이후 시간의 경과나 외부의 조작으로 사라지거나 변조되기 쉽기 때문에 실시간으로 확보하는 것이 중요하다. 본 논문에서는 디지털 콘텐츠 컴퓨팅 환경의 서버 시스템에서 휘발성 정보를 메모리를 기반으로 수집하는 기법을 활용하여 동작 중인 서버에서 위급상황이 발생할 시 필요한 정보를 실시간으로 수집할 수 있는 휘발성 정보 수집 모듈을 제안한다.

Environment perception and three-dimensional (3D) reconstruction tasks are used to provide unmanned ground vehicle (UGV) with driving awareness interfaces. The speed of obstacle segmentation and surrounding terrain reconstruction crucially influences decision making in UGVs. To increase the processing speed of environment information analysis, we develop a CPU-GPU hybrid system of automatic environment perception and 3D terrain reconstruction based on the integration of multiple sensors. The system consists of three functional modules, namely, multi-sensor data collection and pre-processing, environment perception, and 3D reconstruction. To integrate individual datasets collected from different sensors, the pre-processing function registers the sensed LiDAR (light detection and ranging) point clouds, video sequences, and motion information into a global terrain model after filtering redundant and noise data according to the redundancy removal principle. In the environment perception module, the registered discrete points are clustered into ground surface and individual objects by using a ground segmentation method and a connected component labeling algorithm. The estimated ground surface and non-ground objects indicate the terrain to be traversed and obstacles in the environment, thus creating driving awareness. The 3D reconstruction module calibrates the projection matrix between the mounted LiDAR and cameras to map the local point clouds onto the captured video images. Texture meshes and color particle models are used to reconstruct the ground surface and objects of the 3D terrain model, respectively. To accelerate the proposed system, we apply the GPU parallel computation method to implement the applied computer graphics and image processing algorithms in parallel.

이 논문은 현대 정보사회에서 그 기능과 역할에 부응하기 위해 디지털화하고 있는 도서관의 사회적 배경과, 이를 둘러싼 정보환경에 대해 이론적으로 그 의미를 되짚어 보기 위한 것이다. 뉴미디어의 대두, 디지털 정보처리기술의 발달, 정보기록매체의 급속한 발전, 전자출판과 같은 정보생산과 정보유통방법의 혁신은 도서관에 관련된 패러다임을 디지털 도서관 쪽으로 이끌어 나가고 있다. 그러나 디지털 도서관의 또 하나의 기반이 인쇄자료형태로 축적된 정보자료라는 사실도 간과해서는 안 된다. 디지털 도서관은 도서관의 새로운 본질이 아니라, 정보의 디지털화와 정보통신 기술의 발전에 의한 결과로서. 도서관의 목표를 성취하기 위한 한 차원 높은 수단이다.

Recently, Digital Switch has risen as one of the important issues on which academic and industrial world focus in order to bring organizational transformation to a company that wants to adapt itself to the rapidly changing business environment. However, the discussion in the Digital Switch has been so much concentrated in the study of each static system, model of their performance and the development of monitoring each of them, that only few theoretical research has been carried out on the dynamic process of how each system in the organization experienced the change in terms of the level of digital transformation that can occur in the whole organization facing the change of digital environment. Therefore this thesis aims to develop a new model & strategy of switching to global digital by OEM companies in Jeonlabuk-do that enables us to check out and predict the Digital Switch progress. This model is the first Digital Switch process evaluation intended for empirical study, especially by integrating the many indices that have not been examined empirically by the existing studies. We expect that the results from this research will help corporate e-business strategy planners to devise and analyze the Digital Switch strategies effectively by recognizing the companies' current situation in comparison with their previous and other firms' level, respectively.

In this study, users' perceptions and concerns about digital information resources were investigated, focusing on impediments to the use of digital resources, to devise measures for improvement by identifying factors that hinder the use of digital information resources. To achieve the purpose of the study, the research identifies the inconvenien ce factors and establishes the user inconvenience list based on prior research and the current status survey. Based on the derived list, a survey was conducted on users of public libraries. Through this study, it was found that the use of digital information resources can be enhanced by improving the internal library system. Specifically, it refers to improving search performance and accessibility of digital data, providing one-stop services for digital information resources through the operation of an integrated data management system, conducting customized user education, and establishing a digital information resource preservation system, e.g. web archiving. Also, improving the external environment and system, such as contracting with more libraries for digitized data use agreements, strengthening support, unifying the names and classifications of digital information resources, and simplifying the procedure for using digital information resources, is of great importance.

In spite of the rapid development of the public network, the variety of network-based developments currently raises numerous risks factors regarding copyright violation, the prohibition and distribution of digital media utilization, safe communication, and network security. Among these problems, multimedia data tend to increase in the distributed network environment. Hence, most image information has been transmitted in the form of digitalization. Therefore, the need for multimedia contents protection must be addressed. This paper is focused on possible solutions for multimedia contents security in the public network in order to prevent data modification by non-owners and to ensure safe communication in the distributed network environment. Accordingly, the Orthogonal Forward Wavelet Transform-based Scalable Digital Watermarking technique is proposed in this paper.
