국내 정보통신기기시장은 지난해 처음으로 통신기기, 컴퓨터, 부품 등 전분야에 걸쳐 내수 및 생산에서 많은 성장을 보였으며 흑자수지를 이룩하였다. 그러나, 국내외적으로는 국가독점의 KTA를 민영화시킴과 동시에 다수 경쟁체제로 사업이 바뀌고, 미국으로부터는 시장개방요구로 전화기를 맞이하고 있다. 한편 국내정보통신기기 산업의 특징은 양적으로만 성장하였을 뿐 생산 및 수출구조에 있어서 경쟁력이 취약한 상태에 놓여 있다. 즉 정보화 사회의 도래로 기업의 구조변화가 일어남에 따라 내수 시장은 크게 확대되었으나, 수출은 미국, 유럽 일변도로 아직도 다양화되지 못하고 있으며 상품에 있어서도 부가가치가 적은 품목에 그치고 있다.

스마트폰의 다양하고 편리한 기능은 휴대전화기 시장의 급속한 성장을 이루어 최근에는 3000만 사용자 수를 넘어서고 있지만, 악성코드와 같은 공격으로 인한 보안 사고 또한 증가하고 있다. 개방성을 지향하는 안드로이드 플랫폼에서는 스미싱과 같은 신종 공격으로 인해 보안 사고가 최근 크게 이슈가 되고 있는 상황이다. 이러한 취약성을 보완하기 위해 기존 스마트폰 운영체제와 별도의 도메인을 분리하여 금융거래나 사용자의 중요 정보는 별도의 보안 운영체제에서 처리하는 모바일 가상화 기술이 대두되고 있다. 향후 이러한 모바일 가상화 기술이 대중화될 경우, 일반적인 포렌식 조사 절차로는 현장에서 확보한 스마트폰의 보안 영역에서는 사건 조사에 필요한 증거 수집이 불가능할 수 있다. 따라서 본 논문에서는 최근의 모바일 가상화 기술을 살펴보고, 이를 바탕으로 가상화 플랫폼 기반 모바일 장비의 포렌식 조사 방안에 대해 살펴보고자 한다.

Corruption in China became increasingly serious during the early period of its social transition, resulting in severe economic losses and huge challenges to China's government institution, as well as gradually becoming socially widespread. Recently. China's political corruption is an outcome of the attenuated political control, which has been caused by a systemic change from planned economy to market economy since 1978, and the lack of institutionalization to relieve such transition. Besides, the immature market system and state's intervention in the economy are other factors for the corruption. In short, current China's corruption can be regarded as a structuralized phenomenon. This article identified such circumstance by analyzing the scope, degree, and scale of the corruption. Overall assessment of the some factors suggests that present economic modernization is a principal cause for Chinese corruption while the other factors-monopoly power system in the Chinese Communist Party and the transformation of connection-are important but secondary.

As the products of internet appliance, such as digital TV, internet set-top box, and internet phone, are continually produced, the market of real time operating system which controls those products is being highly increased. ETRI developed the extensible real time operating system, Qplus-P, which can be used from PDA to internet set-top box and home server. This paper describes the design and implementation of C standard library for real-time operating system Qplus-P. The Qplus-P C standard library follows EL/IX API level, which is proposed to the real-time operating system international standard by the RedHat. And, the C standard library functions, which are needed to support the Tiny-X and Kaffe, are also implemented. The implemented C standard library can reduce the size of library about 30% compare to the C library that does not follow EL/IX API level.

As the Internet appliances like digital TV, Internet set-top boxes, and Internet phone, are showing up in the market, the economics of real-time operating system (RTOS), which is an essential for controlling those devices, is expanding faster than ever before. ETRI has developed describes RTOS called Qplus-P, targeting various platforms ranging from PDA to Internet set-top box and home server. This paper describes the implementation of graphic window library for Qplus-P. The Qplus-P graphic window library was implemented using tiny-X graphic server and gtk graphic toolkit, which are open source software. To port this library to various aliances, hangul processing, screen rotation, touch screen, and graphic acceleration functions are added to the tiny-X graphic server of the implementd graphic window library. Currently, Qplus-P graphic window is running on ARM-based appliances such as iPaq PDA, Samsung S3C2400 board, Zaurus PDA, and on Home Server that uses x86 processor. Qplus-P graphic library is provided as a of Qplus-P target builder.

Internet is absolutely contributed to information technology revolution nowadays. Internet services such as voice and data, etc. are provided home or small office via home gateway. The development of communication equipment via home gateway is implemented rapidly, and its product various. This paper presents the design and implementation of the VoIP equipment including the telephone function based on the embedded environment and being connected to the home gateway and the PC because of taking 2-ethernet LAN ports. As developing environment, the STLC1502 developed at ST Microelectronics as single chip solution, VxWorks as RTOS, and C language as coding mechanism are used. The verification of the developed systems for the voice test is carried out for the gatekeeper via Internet. The performance parameter is considered as the call processing capacity measuring the time of the call setup and clearing, and the data processing capacity for the file transfer. As a call setup and clearing is about 95ms, the call processing capacity is about 10 calls per second. The data processing capacity is 5.7Mbps in case of file transfer of server and client environment. Therefore the performance result is satisfied in the aspect of the call processing time and the data transfer time in Internet.
