본 논문은 개인용 전자 비서 시스템을 위한 음성사서함의 구현에 관한 것이다. 기존의 음성사서함 서비스는 단순한 메시지 축적서비스에 불과하다. 제안된 전자 비서 시스템을 위한 음성사서함은 음성 정보를 관련 데이터 베이스와 연계하여 개인정보관리시스템에 활용할 수 있도록 한 것이다. 본 논문에서는 음성의 저장과 합성에 ADPCM과 LPC 음성 부호화 방식을 적용하였고, 음악합성에는 FM 음원을 사용하였다. 개인용 컴퓨터에 확장카드 형태로 제작된 제안된 시스템의 서비스 기능은 녹음, 편집, 저장 및 재생기능, 자동발신 및 메시지 전달기능, 동보기능, 자동수신 및 부재중 안내기능, 시보안내 및 음악연주 기능, 전화번호 및 스케쥴 관리등으로 구성되었다.

The entire plant of Leptadenia reticulata (Asclepidaceae) is extensively used as lactogen, traditionally, in veterinary practice. The plants of Dregea volubilis and Pentatropis microphylla (Asclepidaceae) are now used as its substitute and sometimes replace the original drug as traditional lactogen. The lactogenic potential of these drugs was studied in rats using, pup weight, weight of mother, parenchyma percentage, secretary rating, estimation of total protein content and glycogen content of mammary glands tissues as assessment parameters. HPTLC profiles of bioactive extracts were also generated to serve the authentification needs. The results of present studies show that P.microphylla forms a better substitute over D. volubilis.

Synaptobrevin is a kind of vesicle associated membrane proteins (VAMPs) which plays a secretary role in the neuronal synapse and was recently known as the biochemical target of botulinum neurotoxin type B. The structural gene of the synaptobrevin was cloned from mouse brain using RT-PCR technique and was seqrtenced. The deduced amino acid sequence showed that the synaptobrevin protein from mouse brain is exactly the same with that of the rat brain in the amino acid level. The synaptobrevin gene was subcloned into pET3a vector and expressed in E. coli. The molecular weight of the recombinant protein was 19 kDa as expected. Moreover, when the recombinant synaptobrevin protein was incubated with the native neurotoxin of Clostridium botulinum type B, it was cleaved by the toxin in a time dependent manner. This implies that the recombinant synaptobrevin protein and the native toxin are reacted in the same way as the native synaptobrevin did in the neuronal cells.

The study on the new measurement method of room acoustics is now in process in the ISO TC43/SC2/WG24 New standard(WD 18233) is dealing with the MLS, swept sinusoidal signal and impulse. This working group is composed of more than 20 specialists in 10 countries and the convener is professor J.H.Rindel in technical university of Denmark. The meeting of WG24 was held in the DIN, Berlin at 23rd. this september and the results was sent to the secretary of ISO TC43/SC2 for the circulation. Brief information of ISO/WD18233 and the result of this meeting is given here.

The paper analyzes a copyright owning firm's incentive to enforce its copyright in the presence of file-sharing networks. I devise a two-period model where a copyright owner sells two different versions of a creator's information good, and show that the firm's overall profits are enhanced by a strategy of differential inter-temporal enforcement of the copyright protection, compared to strategies of no enforcement or full enforcement in both periods. If the firm enforces no copyright protection in the first period, the low-valuation consumers may make and consume copies that are imperfect substitutes for the original information good. If there is a significant increase in the willingness-to-pay of some low-valuation consumers after they experience the information good, the firm can extract the increased consumer surplus by enforcing a positive level of copyright protection in the second period. Social welfare, however, is maximized in the case of no enforcement.

This article presents a brief reconstruction of the historic journey of Benedict the Pole and John of Pian de Carpine, the first known Europeans after A.D. 900 who completed a successful return journey east of Baghdad and gave surviving accounts of their travels. The article, which focuses mainly on the role of Benedict the Pole, is divided into five parts: the reasons and organization of the deputation sent to the Mongols by Pope Innocent IV from 1245-1248, the route travelled by the Papal envoys, the existing versions of the two surviving accounts of the mission, the role of Benedict the Pole as the secretary and translator to the papal legate Pian de Carpine, and the outcome of the journey as seen from the perspective of Europe-Asia contacts.

In today's dynamic and turbulent business environment, in order to become globally competitive, many companies are trying to get closer to the customer and deliver value added product and services in the shortest possible time which demands integration of business processes of an enterprise, Enterprise Resource Planning (ERP) is such a strategic tool, which helps the company to gain competitive edge by integrating all business processes and optimizing the resources available. This paper throws light on how ERP evolved, what makes up an ERP system and what it has to offer to the industries. The paper includes the role of ERP, perception of ERP value, ERP plan and direction. The author also argues checkpoints as a preview to ERP introduction.

This paper proposes a novel computer human interface, named Virtual Wireless Microphone (VWM), which utilizes computer vision and signal processing. It integrates real-time face tracking and sound signal processing. VWM is intended to be used as a speech signal input method for human computer interaction, especially for autonomous intelligent agent that interacts with humans like as digital secretary. Utilizing VWM, the agent can clearly listen human master's voice remotely as if a wireless microphone was put just in front of the master.
