As the housing market is changing, there's a trend that the brand marketing through the TV-CM is increasing. Thus, this study purposes to identify the characteristics and the limit of the marketing on the housing market by analyzing the elements of marketing on TV-CM in the 2000's and comparing the representative business enterprises with each other. In the case of television advertisement, it is dominated by the emotional advertisement which is sensitive and image-oriented than the rational one. In addition, 1 pointed out some problems resulted from the transitional feature of the television advertisement and the gap between the real apartment and its brand image appeared on the advertisement, then I will present corresponding solutions.

WRC-97에서 HAPS 개념이 도입된 후, HAPS 이용 주파수 대역으로 IMT-2000 대역과 Ka 및 V 대역이 지정되었다. IMT-2000 대역에 대한 공유 및 규정 연구는 WRC-03에서 종료되었으나, Ka 및 V 대역에서 타 무선업무와 HAPS를 이용한 고정업무 간의 기술적, 운용적 그리고 규정에 관한 연구를 지속하고 WRC-07에서 연구결과를 검토하기로 하였다. 본 고에서는 WRC-03 회의에서 결의한 IMT-2000 서비스를 제공하는 HAPS 시스템의 이용에 관한 규정 현황을 알아보고, 현재 ITU-R에서 논의중인 Ka및 V 대역에서 HAPS 시스템 활용을 위한 규정 연구 현황을 살펴보고자 한다.

PROSET2000 that is integrated protective management system had developed and used in order to automate the setting process of protective relays in transmission system protection. PROSET2000 have database for relay setting and automated for relay setting program within. This paper proposed PCM current differential relay setting program point of Object Oriented Programming paradigm using Unified Modeling Language about additional relay in PROSET2000. Nevertheless each relay uses same current differential but setting method is different. This paper discribed different thing about setting method of each relay and evaluated more effective and corrective relay setting program using UML.

This paper presents the real-time implementation of an AMR (Adaptive Multi Rate) vocoder which is included in the asynchronous International Mobile Telecommunication (IMT)-2000 mobile ASIC. The implemented AMR vocoder is a multi-rate coder with 8 modes operating at bit rates from 12.2kbps down to 4.75kbps. Not only the encoder and the decoder as basic functions of the vocoder are implemented, but VAD (Voice Activity Detection), SCR (Source Controlled Rate) operation and frame structuring blocks for the system interface are also implemented in this vocoder. The DSP for AMR vocoder implementation is a 16bit fixed-point DSP which is based on the TeakLite core and consists of memory block, serial interface block, register files for the parallel interface with CPU, and interrupt control logic. Through the implementation, we reduce the maximum operating complexity to 24MIPS by efficiently managing the memory structure. The AMR vocoder is verified throughout all the test vectors provided by 3GPP, and stable operation in the real-time testing board is also proved.
