Through comparison and evaluation of various HDD systems for PC such as magnetic HDD, Intel turbo memory and Solid State Drive (SSD), an optimized HDD system to improve booting speed proposed. For the study, conventional magnetic HDD, magnetic HDD with Intel turbo memory, SSD and SSD with Intel turbo memory are used. The evaluation is performed based on a full notebook machine with Intel SantaRosa platform and MicroSoft Windows Vista.

The speech of Sino-Korean has been evolved from geopolitical cause since 1945. The aim of this study is to collect Yanji dialectal speech and to compare with South Korean dialectal speech. Twenty Yanbian university students participated as informants. Acoustic speech informations are analyzed using the Multi-Speech Windows Vista version. Dialectal speech characteristics of Yanji sino-Korean showed posterior vowel /${\alpha}$/, neutralization of mid-vowel /o/ between /o/ and /Ɔ/. Lenis stop sound showed the tendency of glottalization based on VOT value. Sibilant sound contains aspiration following constriction and lateral /l/ realized the approximant /r/.

마이크로소프트(MS)의 윈도우 비스타(Vista, 이하 비스타)는 윈도우 XP의 뒤를 잇는 버전으로 06년 11월말 기업용이 출시되었고 2007년 1일 31일 개인사용자용이 출시되었다. 비스타는 이전 버전인 윈도우 XP에 비하여 한층 강화된 보안기능을 탑재하고 있어 인터넷 사용시 악성코드 감염 등의 위험이 많이 줄어들 것으로 예측되고 있다. 그러나 비스타에서는 하드디스크 전체를 암호화 할 수 있는 BitLocker 기능 등이 추가되어 포렌식의 관점에서 보면 기존 XP와 달라진 점이 다수 존재한다. 본고에서는 기존 XP와 비교하여 비스타에서 변경된 부분을 포렌식 관점을 중심으로 기술하고자 한다.

윈도우즈 비스타(Windows Vista)는 용이성, 안전성, 연결성, 엔터테인먼트 기능의 향상을 기반으로 한다. 특히 사용자계정 제어, 악성 프로그램에 대한 보호 기능, 인터넷 익스플로러 7(Internet Explorer 7)의 보호 모드, Windows Defender 등의 제공으로 개선된 보안기능을 제공한다. 기존 응용 프로그램의 대부분은 관리자 권한만을 고려하여 설계 및 작성되었으므로 보안이 강화된 윈도우즈 비스타에서는 호환성에 대한 문제가 제기되었다. 본고에서는 윈도우즈 비스타로 인해 발생한 문제점을 해결하기 위해 새로운 플랫폼이라는 관점에서 대응책을 제안한다.

This paper describes how using the XPS Document technologies of Windows Vista support and enhances interactions with the structural design and construction process. It illustrates the document workflows and the document life cycle in a typical construction base knowledge system. It provides engineers and decision makers and implementers with information about this new technology and how they can apply it to their design and construction models. The paper also highlights opportunities for the new format of data exchange in the recent efforts to develop National Management System Standards for Transportation Applications to benefit from these emerging technologies.

Ultrafiltration is an emerging technology for drinking water treatment because it produces better water quality as compared with conventional treatment systems. More recently, the combination of UF technology with other processes in order to improve its performance has been observed. These associations aim to maximize the contaminants removal and reduce membrane fouling. The operational performance of contaminants removal and water production of two UF pilot plants was compared. The first plant (Guarapiranga) was fed with raw water and the second plant (ABV) with pre-treated water by the coagulation, flocculation and sedimentation processes at Alto da Boa Vista WTP (Sao Paulo, Brazil). Both units operated continuously for approximately 2,500 hours, from September/2009 to January/2010. The results showed that the ABV UF pilot plant was able to operate at higher specific fluxes (6.2 $L.d^{-1}.m^{-2}.kPa^{-1}$ @ $25^{\circ}C$) than Guarapiranga (3.1 $L.d^{-1}.m^{-2}.kPa^{-1}$ @ $25^{\circ}C$). However, the number of chemical cleanings conducted in both pilot units during the considered operation period was the same (4 chemical cleanings for each plant), which shows that the pre-treatment reduced the membrane fouling. The water quality at ABV for all the variables analyzed was better, but the feed water quality was also better due to pretreatment. The rejection values for the different contaminants were higher at Guarapiranga mainly because of a pollution load reduction after pre-treatment at ABV. Even with the better performance of the ABV UF pilot plant, it is necessary to take into consideration the complexity of the complete treatment system, and also the costs involved in the construction and operation of a full-scale treatment unit.
