Advanced FeedForward method use Predistortion method and FeedForward method simultaneously. This method better than original Feedforward method in linearity and supply smaller power to pre-power amplifier than different methods, and then it has higher power efficiency and better linearity than original Feedforward method. A linear power amplifier using Advanced feedforward method is designed and fabricated for IMT-2000 transmission system (2110㎒ -2170M㎓). This amplifier's power gain is about 40㏈ and it's 3-rd IMD(Intermodulation distortion) are smaller than about -55㏈c(@ 10MHz).

어느 때나 장소에 구애받지 않고 원하는 정보를 제공할 수 있는 이동 컴퓨팅 기술들이 활발히 연구되고 있다. 현재 인터넷은 대부분이 유선망에 기반을 두고 있다. 최근 IMT-2000의 개발로 무선망에서의 인터넷 개발이 급속히 진전함에 따라 적절한 QoS를 보장할 수 있는 무선망 프로토콜의 제공이 필요하다. 이동 컴퓨팅 환경에서 이동 호스트가 앞으로 핸드오프해 새로 접속할 기지국만을 멀티캐스트 그룹으로 취하여 무선 링크 상에서 TCP의 성능저하를 줄일 수 있는 무선TCP 프로토콜을 제안한다.

This study aims to investigate the eco-friendly planning methods for a sustainable apartment houses in the Metropolitan area of Seoul. Eco-friendly plans that considers the environmental issues were attempted from the beginning of 2000s, and since then, many apartment houses in Korea were built using this concept. They were, however, generally focusing on the physical and spatial aspects of the site plan. After the Seoul C40 weather summit conference in 2009, the low carbon green housing standard has been emphasized and thus the chemical concept was added to the existing physical planning methods. Under such a background, this study intends to investigate the eco-friendly plans for the apartment houses in the 2000s. This includes an ecological network plan, an ecological base plan, a building greening plan, a water treatment plan, and an energy saving plan. Based on the analysis and synthesis of these planning methods in the early 21st century, it would be possible to set up a proper future plan to enhance the sustainable built environment in the housing industry in the coming years.

The terrestrial television broadcasting has increased the number of the specialized job drama in the programming in 2000's, for overcoming the limit of the materials and reflecting the new sociocultural phenomenon valuing the specialized job. This drama benefits from good audience and huge fans, while the low average rate of audience shows the limit of competitiveness of this new genre. The text analysis clarifies three traits of the specialized job drama. At first, this genre is characterized by the variety of materials and the attempt of realistic description. Then, its narrative structure is organized so as to develop a story based rather on the success of career than on the relation of love. Finally, its last trait lives in the character of the heroes which is a creation based on the narrative structure.

The tendency of exuberant multi-everything, enormous volumes and decoration has been showed in fashion since the 21st century. This tendency is very interesting in contrast to the tendency of restraint, simplicity and removing decoration which has been showed in the modern fashion throughout the 20th Century and especially minimalism fashion in the 1960s and the 1990s with the expectation of New Millenium. Maximalism is this kind of exuberant expression emerged since 2000. However, studies about maximalism in fashion have not been performed enough. Thus this study tried to analyze the aesthetic characteristics of maximalism in the modern fashion according to the previous studies of maximalism in design and architecture with social cultural background. The scope of this study was from 2000 to 2006, and this study was performed through literature survey with demonstrative analyzation of fashion collection photographs. The results are as follows; Maximalism has the meaning of 'maximum oriented-ism' and has aesthetic view of 'more/bigger is more beautiful.' The formativeness of maximalism in modern fashion was analyzed as fusion, enlargement, decoration, and fantasy. The internal meaning was analyzed as recovery of human being through pursuing of sensibility, fun and newness.

This paper empirically explores the pattern of causality between bank lending and housing prices in Korea over a period of the early 1990s to the end of 2000s by employing a long term cointegration and short-term time series regression analysis. Although the contemporaneous correlation between bank lending and housing prices is large, the analysis shows that the intense interaction between credit growth and bank lending to household arises from a growth in banking lending responding to an increase in housing prices. In addition, the regulatory change such as the introduction of financial constraints on bank loans such as LTV and DTI in the early and mid-2000s has played a significant role in stabilizing financial and real estate markets.

환경부 고시 제2000-71호에 의하면 휘발성 유기화합물질의 규제제품 및 물질 종류는 methanol, acetaldehyde 및 toluene 등을 포함하여 37종으로 고시하고 있다(환경부, 2000). 미국의 경우 1997년 VOCs 발생원에 대한 배출량 산정을 보면 총 19,216 ton/yr의 VOCs가 배출되고 있으며, 이 중 7,660ton/yr인 39.86%가 자동차에서, 용매 이용시설에서 33.74%, VOCs 저장 및 운송에서 7.17% 및 석유관련 산업에서 2.80% 등의 순서로 배출되는 것으로 보고되고 있다(Noel do Hovers, 2000).

현재 IMT-2000서비스를 위한 패킷 전송 망의 표준화는 특히 북미 방식의 3세대 패킷 데이터 시스템과 유럽의 GPRS, 이 두 가지 분야를 중심으로 연구가 진행되고 있다. 지금까지 국내의 이동통신은 CDMA를 중심으로 발전해 왔고 WAP 표준이 나온 후로도 계속해서 CDMA방식에 WAP을 적용하려는 노력이 계속되고 있다. 하지만 WAP은 GSM의 성능을 개선하기 위해 등장한 것이고 특히 GSM의 새로운 기술은 GPRS에 WAP을 적용시키면 이동 간에 인터넷 서비스는 물론 다양한 응용을 윤활하게 서비스할 수 있다. 본 논문에서는 GPRS 기반 하에 WAP을 연동시킬 수 있는 방안을 기술하고자 한다.

This study investigates the research trends of SMEs and technological innovations in the last 40 years. Research topics and methodological trends were analyzed for 114 academic papers deals with technology innovation in SMEs. In terms of research subjects, there have been interested in the technology capability and technology accumulation of SMEs in the 1990s, but after the 2000s, research on external open innovation and innovation performance has increased. The empirical analysis studies using primary or secondary data were dominated since the 2000s. We suggest some future research directions, more systematic innovation processes in SMEs, the interactions between technology innovation and external environments, and advanced methodologies on SMEs' technology innovation studies.
