지난 50여년간 사용해 왔던 아날로그TV가 디지털로 전환되면서, HDTV급 고화질과 CD급고음질의 TV 서비스를 안방에서 즐길 수 있게 되었다. 그러나, 사회가 매우 다양화됨에 따라 시청자의 활동성 및 생활 패턴도 과거와는 매우 달라졌으며, 휴대폰, PDA, 노트북 컴퓨터 등 휴대용 기기가 일반화됨에 따라 이동 중에도 선명한 화질의 TV를 즐기고자 하는 요구가 급속히 증대되고 있다.(중략)

무선통신과 관련된 대표적인 프로토콜로써 Bluetooth, IEEE 802.11, HomeRF등이 있다. 이러한 프로토콜들을 이용한 제품들이 생산되면서, 동일한 환경에서 어느 프로토콜이 더 적합한지를 결정할 필요가 있다. 본 논문에서는 Bluetooth와 IEEE 802.11의 표준을 기반으로 무선 노트북이나 이동전화에서의 성능을 평가하고 그 결과를 보여준다.

전자부품 및 시스템의 고속/고밀도화 추세에 따라 발열밀도가 계속증가하고 있다. 최근 팬티엄 II 급이상의 노트북 컴퓨터의 CPU에서는 칩당 발열량이 10W 이상으로 증가하고 있고 패키징 공간의 제한 때문에 소형히트파이프를 이용한 냉각이 많이 적용되고 있다. 본 연구에서는 모세압구동력이 크고 생산성등이 고려된 편조 형태의 새로운 윅을 개발하였으며 , 노트북 컴퓨터의 CPU 등 소형 전자부품냉ㄱ가에 적용가능한 직경 3, 4 mm 히트파이프를 설계 및 제작하였다. 직경 3, 4 mm Miniature Heat Pipe (이하 MHP) 의 작동특성은 일반적인 중형히트파이프와 다르므로 MHP 의 열전달 특성 및 작동성능에 미치는 각종 인자들의 영향을 파악하고자 성능시험을 수행하였다. 고려된 작동인자로는 작동유체 충전률, 전체 파이프길이 및 증발부, 응축부길이, 설치 경사각, 윅의 가닥수, 열부하 등이다. 작동인자의 영향과 관련된 연구결과는 향후 패키징을 위한 응용연구의 기초자료로 활용할 수 있을 것이다.

An inverted-F antenna for wireless local area network(WLAN) is presented. The proposed design is based on the typical dual-band planar inverted-F antennas(PIFA), which have two tunable resonant modes. The low-profile antenna is built by stamping and designed to be mounted on the metal frame of the laptop LCD panel. The obtained antenna can perform in 2.4 GHz and 5 GHz bands and be adopted for other wireless applications. All the measurements are performed in the actual test fixture.

This research, which was experimented by dividing tangible and intangible products, established the influence that affects recovery for consumers' complaint behavior and behavioral intention as per each different compensation program. In Experiment 1, the consumers, who experienced complaint behavior owing to company's mistake, have preferably recovered through the compensation program offered by the company. However, there was a significant difference in preference recovery between products that caused complaint behavior. According to the study result, the more clear preference recovery was shown in the case of purchasing laptop than the case of dining in family restaurant. Additionally, the consumers' emotion recovery was possible through compensation.; There was a emotion recovery disparity depending on product type between purchasing laptop case and dining in family restaurant case. The consumers, who experienced complaints, were only able to recover their preference, emotion, and behavioral intention through compensation of which recovery was greater in tangible product case than ordinary service. Meanwhile, there was no distinct difference between recovery compensation types even though the products were identical-type ones whereas it appeared that such tangible product which showed greater purchasing effort as laptop computer was more effective in stimulating emotion response. In Experiment 2, the purpose was to find out the difference between complaint behavior and its recovery process shown after purchase by Korean and Japanese college students, who have different consumer purchasing habits. The both consumers of the two countries, who experienced complaint behavior, demonstrated precise difference in preference recovery while the emotion and behavioral intention exhibited no disparity between the two consumer groups. In this experiment, it was learned that Korean college students were show-off purchase type consumers while on the other hand, the Japanese college students were famous product purchase type consumers. Thus, there was a clear difference in laptop computer purchase process and post-purchase evaluation between these two groups. In particular, the Korean college students had quicker preference recovery through compensation than the Japanese college students on account of their tendency to be consciousness of others. Nevertheless, there was no difference between the emotion recovery and re-purchase recovery and therefore, the compensation program for complaints was proven to affect the emotion and behavioral intention.
