대용량 멀티미디어 메일을 위한 분산 멀티미디어 스트림 상의 데이터서버의 설계 및 구현
박용희(Yong-Hee Park),전성미(Sung-Mi Chon),고희선(Hee-Seon Ko),임영환(Young-Hwan Lim) 한국정보과학회 2001 한국정보과학회 학술발표논문집 Vol.28 No.1B
기존의 멀티미디어 메일은 대용량 메일이라 개인 사용자에게 그 부담이 크지 않을 수가 없었다. 이에 인터넷 기반에서 멀티미디어 데이터서버에 대해서 많은 제품뿐만 아니라 서비스에 대한 QoS 만족을 위해 많은 연구실에서 연구해 왔었다. 특히나, VOD 서버나 인터넷방송을 위한 서버의 구축을 위해 많은 연구가 있어왔다. 본 연구는 인터넷기반이 아닌 본 연구실의 프로덕트인 VIP(Visual Interface Player)와 멀티미디어 스트림 엔진인 Essence 를 이용한 멀티미디어 동영상 메일 전송 기법과 Essence 를 이용한 동영상 멀티미디어 메일을 저장하는데 필요한 Essence 내에 데이터베이스를 지원하기 위한 DBMedium 개발과 데이터베이스 라이브러리를 개발하기 위한 일련의 과정을 제안하고 있다.

Silicon micromachining technology can be used to build microsensors and actuators by using tools derived from standard IC processing. For the silicon micromachining the etching characteristics of tetramethyl ammonium hydroxide (TMAH) by dissolving silicon powder or silicic acid have been studied. The 3, 5 and 10wt.% TMAH solutions, with dissolved silicon powder (6g/l) or with dissolved silicic acid(Si(OH)4, 16g/l) were used. And ammonium peroxydisulfate (APODS, 2g/l) dissolved in the solutions were also used. The etch rates of silicon and the etched surface roughness were observed with various etching conditions. The crystallographical aspect on the crystal orientation of silicon have been studied. With sufficiently fresh solutions, these TMAH concentration and combination of etchants, provide repeatable etch properties, does not attack exposed aluminum or silicon dioxode, and provide smooth (100) silicon surfaces.

A micro-vacuum sensor has been fabricated by using silicon micromachining techniques and platinum thin film. NON insulator was deposited by LPCVD and APCVD methods. The insulator diaphragm was fabricated by silicon anisotropic etching in TMAH solution. Thin film platinum heater and temperature detector were deposited by rf sputtering method and patterning was performed by means of lift-off method. Deposited platinum heater and temperature detector have been shown a linear Ⅰ-Ⅴ characteristics. TCR(temperature coefficient of resistance) of thin film platinum heater and temperature detector was about 0.0042/℃. Fabricated vacuum sensor was measured in the range of 1x10³Torr to 1×10² Torr, and shows a good linear operating characteristics in the range of 1x10² Torr에서 1x10˚Torr.
