Using data from the 2001 Computer and Internet Use Survey by the National Statistical Office, this study investigated digital divide among women aged between 20 and 55. Following were the major findings. first, two-thirds of women did not use Internet even though many of these had Internet access at home. Second, those who did not have Internet access at home, those with a lower level of educational attainment, those with blue color or service occupations, and those with higher age were less likely to use Internet than their counterparts in these socio-economic variables. Third, expanding Internet infrastructure would not improve Internet use of the Elderly. Forth, the majority of those who did not use Internet did not recognize the Internet itself. Based on the result the policy implications for digital divide were suggested.

There have been many streaming servers that provide a large number of contents for a user's preference. General purpose streaming sewer makes use of a RTSP protocol for streaming controls such as message passing with client players. To date, there has been minimal research regarding streaming server's performance test tools. For measuring streaming server's performance, performance evaluation technique is needed and also achieved by RTSP based controls, a server's performance result and its miscellaneous test tools such the PseudoPlayer for pumping data to a specified port and the PseudoMonitor for gathering information. In this paper, We implement a test toolkit for evaluating a streaming server's performance and show the case of its application

디지털 통신 네트워크 기술의 발전에서 인터넷 기술과 스마트 홈 가전기기의 확산은 고속/고품질 홈 네트워크에 대한 필요성을 증가시키고 있다. 홈 네트워크에서 가전기기와 컴퓨팅 기기가 증가함에 따라 홈 네트워크의 데이터 트래픽은 증가할 것이 명백하다. 다양한 홈 네트워크 기기는 멀티미디어 콘텐츠를 얻기 위하여 인터넷 서버에 접속하길 원한다. 따라서 본 논문에서는 가정내에서 이더넷이나 유무선 기술을 사용하기 위해 네트워크에 연결된 디지털 가전기기를 위한 TLC(Telephone Line Carrier) 시스템을 소개한다. 미래의 홈 네트워크 환경에서 TLC 기반의 스마트 홈 네트워크의 주된 목적은 저가격, 쉬운 설치, 고성능, 넓은 영역을 만드는 것이다. 본 논문에서는 스마트 홈 네트워크를 위한 전화선로 통신시스템의 채널용량을 송신전력, OFDM 반송파의 수, 채널손실, 잡음손실에 따라서 정량적으로 비교, 분석하였다.

According to the OECD Report, Korea passed the first threshold to an "aging society" in which the elderly aged over 65 make up at least 7 percent of the population in 2000, and in 2018, are due to pass the second to an "aged society" in which they make up at least 14 percent-just 18 years later. It took France (starting in 1864) 115 years to complete this transition. Even Japan, legendary for the rapidity of its aging, required 24 years. It means Korea has to prepare for the aging of its population within a very short time without mistakes. Meanwhile, in a 2005 survey of the elderly, 85.5% of them preferred aging in place to moving to elderly care facilities. That means housing planning for the elderly which provides them with independent living needs to be considered seriously. The digital technology integrated home may be one of the alternatives to support this idea. In order to find a way to user oriented digital homes for the elderly, this study identified the their needs on the physical features of the ideal home and the digital services necessary through digital life scenarios.

최근 건설업체는 주택상품 기획시 홈네트워크를 차별화 요소로 사용하고 있으나 공급자로서의 역할만 하고 있을 뿐 앞으로 창출될 거대한 규모의 홈네트워크 시장에 대한 적절한 수익모델을 발견하지 못하고 있는 실정이다. 관련업계에서는 유비쿼터스(Ubiquitous)시대를 대비하여 국가성장동력으로 삼으려는 정부의 정책하에 관련 가전, 통신, 방송업계의 시장선점을 위한 각축이 진행중이다 한편 인구구조 및 라이프스타일의 변화 등으로 인해 디지털화된 주거환경에 대한 소비자의 요구도 높아지고 있다 그러나 현재 거주자들에게 제공되고 있는 대부분의 홈디지털 서비스는 정책적 뒷받침의 부족과 분양가상승 우려 등으로 초보적인 수준에 머물러 있는 것으로 조사되었다. 미래주거환경을 선도해야할 건설사들에게 고객특성별 수요분석을 통한 품목 개발과 적극적인 수용의지가 요구되고 있다.

The purpose of this study is to analyze the emotional color of home office and the trendy color with special comparison of office and library colors, and to suggest the harmony of color combination of home office based on the emotional color of this analytical data. this study, the Color Syntax Program, digital tool for color analysis of images is used. The results of this study are as follows. Firstly, the main color of home office images shows three color classifications of YR-Y, Y-GY, R-YR, and with relatively high ratios of YR-Y in the color of home offices, and B-PB, GY-G in offices and libraries. Secondly, from the point of emotional aspect, the trendy color of the home office can be classified into four color image categories: 'natural', 'peaceful', 'mild', and 'noble'. Under those categories this paper proposes 10 color harmony scheme that can be applied to color of home office interior design.

유비쿼터스 환경은 디지털 홈 기기들이 시간과 공간에 제약을 받지 않는 멀티미디어 서비스를 제공한다. 하지만, 디지털 콘텐츠의 사적복제 보장을 통한 콘텐츠의 이용 편리성 보장(Fair Use)이 이루어지지 않고 콘텐츠의 무차별적인 배포와 불법 콘텐츠의 사용 등으로 인해 피해를 주고 있는 것이 현실이다. 이러한 문제점을 해결하기 위해 등장한 DRM 시스템은 단말기에 저장된 라이선스의 보호와 콘텐츠의 재배포에 따른 라이선스 관리를 수행하지 못하는 문제점이 있다. 본 논문에서는 유비쿼터스 환경에서 DRM 시스템의 문제점을 해결하기 위한 대안으로서 콘텐츠와 라이선스에 대한 오용행위 감사 및 불법 대규모 유통을 사전에 차단하고 법적 대응을 위해 디지털 증거 생성 및 관리가 가능한 디지털 포렌식 모델을 제안한다.

A Smart Home is a technically expanded from home network that gives us a comfortable life. But still there is a problem such as mal function of devices and intrusions by malicious parties since it is based on home network. The intrusion by malicious parties causes a critical problem to the individual's privacy. Therefore to take legal actions against to the intruders, the intrusion evidence collecting and managing technology are widely researched in the world. The evidence collecting technology uses the system which was damaged by intruders and that system is used as evidence materials in the court of justice. However the collected evidences are easily modified and damaged in the gathering evidence process, the evidence analysis process and in the court. That's why we have to prove the evidence's integrity to be valuably used in the court. In this paper, we propose a mechanism for securing the reliability and the integrity of digital evidence that can properly support the Computer Forensics. The proposed mechanism shares and manages the digital evidence through mutual authenticating the damaged system, evidence collecting system, evidence managing system and the court(TTP: Trusted Third Party) and provides a secure access control model to establish the secure evidence management policy which assures that the collected evidence has the corresponded legal effect.

Video Content owners seek to squeeze the maximum amount of revenue from their assets via distribution into more territories. Digital Cinema Package(DCP), trusted solution to distribute protected content to theaters, caters to relatively small user base, which limits revenue. With the growth of the Internet & other digital media, the economics of media content has changed dramatically. Security remains main concern to deliver content to millions of consumers using intelligent digital display devices like Tablets, Smartphones, Smart TVs, Desktop & Laptop. By making the video content available to this segment securely, content owners will benefit from increased revenue. Through this paper we propose Open Source HomeDCP model to distribute the content to home users for offline viewing. We propose to include other open source CODEC than JPEG2000/MPEG2, which are specifically designed for theatrical performance. Final image size will be further reduced considering the display device resolution where video will be finally played. Key Delivery Message(KDM) system to be altered to suit new devices. This will be a big boost to Content Economy as content owners would be able to distribute the content securely to the wider audience & ensure more revenue.
