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 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.

SK Telecom은 2000년 10월 세계 최초로 기존 IS-95A/B망에서 지원하였던 속도인 14.4Kbps나 56Kbps 보다 훨씬 빠른 최고 144Kbps로 무선인터넷이 가능한 CDMA2000 IX를 상용화 하였다. 또한, 2002년 1월에는 CDMA2000 IX보다 15배 이상 빠른 최대 2.4Mbps가 가능한 동기식 3세대 망인 CDMA2000 IxEV-DO를 세계 최초로 상용화 하였다. 이러한 초고속 무선 인터넷 서비스를 위해서 패킷 데이터 처리에 필수적인 PDSN(Packet Data Serving Node), HA(Home Agent), AAA(Authentication, Authorization and Accounting) 등의 노드들로 구성된 Packet Core Network(이하 PCN)이 도입되었으며, 이에 대한 운용 및 관리 방안이 중요한 issue로 등장하였다. 본 논문에서는 기존의 음성 서비스 관리를 위한 망관리 시스템(Network Management System)과는 다른 개념으로 관리되어야 할 패킷 서비스를 위한 NMS 구축 방안을 제시하고, 필수적인 관리 정보 및 서비스 관리를 위한 방향을 제시한다.

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.

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.

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.

Using InGaP/GaAs HBT power cells with a 2.0${\times}$20$\mu\textrm{m}$$^2$ emitter area of a unit HBT, a two stage MMIC power amplifier has been developed for IMT-2000 handsets. An active-bias circuit has been used for temperature compensation and reduction in the idling current. Fitting on measured S-parameters of the HBT cells, circuit elements of HBT's nonlinear equivalent model have been extracted. The matching circuits have been designed basically with the extracted model. A two stage HBT MMIC power amplifier fabricated using ETRI's HBT process. The power amplifier produces an 1-㏈ compressed output power(P$\_$l-㏈/) of 28.4 ㏈m with 31% power added efficiency(PAE) and 23-㏈ power gain at 1.95 GHz in on-wafer measurement. Also, the power amplifier produces a 26 ㏈m output power, 28% PAE and a 22.3-㏈ power gain with a -40 ㏈c ACPR at a 3.84 ㎒ off-center frequency in COB measurement.quency in COB measurement.

Objectives Previous literature on the prescription change among patients with schizophrenia mainly focused on antipsychotics. This study investigated chronological change in the patterns of discharge medication among inpatients with schizophrenia at a psychiatric inpatient unit of a university-affiliated hospital. Methods All admission records at a psychiatric unit of Hanyang University Guri Hospital with discharge diagnosis of schizophrenia during two different five-year time frames (1996-2000 and 2006-2010) were reviewed including the demographic and clinical data and discharge medications. The data were gathered from a total of 207 patients (95 in 1990s and 112 in 2000s). Results The frequency in use of atypical antipsychotics (p < 0.01), antidepressants (p < 0.05), beta-blockers (p < 0.01), and benzodiazepine (p < 0.01) was significantly higher in 2000s. Anticholinergic drugs were less likely used in 2000s (p < 0.01). We did not find significant differences in the equivalent dose of antipsychotic drugs, the use of mood stabilizers and cholinergic drugs between two time frames. Conclusions Increased proportion of atypical antipsychotics and decreased use of anti-parkinsonian drugs are in line with literature. Our results show that more diverse classes of psychotic medications are used for schizophrenia in recent years. It is likely that psychiatrists are becoming more conscious of negative symptoms, anxiety, and depression in the pharmacotherapy of schizophrenia as well as positive symptoms of the illness.

This paper proposes a novel transmit diversity technique, namely symbol split orthogonal transmit diversity (SS-OTD). In this technique, full path diversity and temporal diversity are achieved by combining orthogonal transmit diversity technique (OTD) technique with the symbol splitting method proposed by Meyer. Its performances is simulated for fundamental channels associated with the forward link of the IS-2000 system, and then compared with those of OTD and space-time spreading (STS). Our proposed method offers a 0.5-7.7dB performance improvement over OTD under various simulation environments and its performance is similar to STS. Moreover, compares with that of STS, the peak-to-average power ratio (PAR) of transmitted signals in SS-OTD is reduced by a maximal 1.35dB, which decreases the complexity of base station RF devices, such as power amplifiers. Thus, SS-OTD is comparable to STS in performance and superior to STS in the cost and efficiency of base station RF devices.
