A simple and rapid method is described for extending the 5'- or 3'-end genomic sequence of a known partial sequence by only a single round of PCR. This method involves digesting and ligating genomic and plasmid DNAs, and amplifying the 5'-upstream or 3'-end downstream sequence of the known DNA sequence, using two primers, one gene specific and the other plasmid specific. A single round of PCR amplification is sufficient to produce gene-specific bands detectable in gels. By using this approach, 5'-end genomic sequence of the D-amoeba sams gene was extended.

In this report, we present a scalp defect reconstruction with lateral arm free flap. We highlight the difficulty in obtaining a recipient vein and the venous drainage managed through an open end of the donor vein. A 52-year-old woman presented with a pressure sore on the left scalp. A lateral arm free flap was transferred to cover this $8{\times}6cm$ defect. The arterial anastomosis was successful, but no recipient vein could be identified within the wound bed. Instead, we used a donor venous end for the direct open venous drainage. In order to keep this exposed venous end patent, we applied heparin-soaked gauze dressing to the wound. Also, the vein end was mechanically dilated and irrigated with heparin solution at two hour intervals. Along with fluid management and blood transfusion, this management was continued for the five days after the operation. The flap survived well without any complication. Through this case, we were able to demonstrate that venous congestion can be avoided by drainage of the venous blood through an open vessel without the use of leeches.

To use the SLIM for servo system, the exact account of thrust about the initial speed is needed, but analyzing by equivalent circuit analyzing methode such as rotary induction motor, the error occurs because of the end effect. So, we applied the equivalent circuit considering the end effect of SLIM in this paper. The current control system is advanced the space vector pulse width modulation by using high arithmetic performance microprocessor such as DSP. In this paper, we use the dynamic characteristic analyzing methode that can calculate efficiently the end effect by using equivalent circuit methode in the operating SLIM system modeling and examine the output characteristics of SVPWM with PI controller.

LIM have mainly different point considering rotary induction motor, that is end effect. In this paper described that, end effect, adding to the rotary induction motor, They can be designed because of affects magnetizing inductance and series resistance in the d-axis circuit. After LIM modeling, using SVPWM, apply to vector control this model. We can verify feasibility of field onented control technology can control speed by simulation.

The spot welded sections of automobiles (hat and double hat shaped sections) absorb most of the energy in a front-end collision. The target of this paper is to analyze the energy absorbing capacity of the structure against the front-end collision, and to obtain useful information for designing stage. Changed the spot welded pitches on the flanges, the hat and double hat shaped section members were tested on the axial collapse loads at various impact velocities. It was expected that para-closed sections would show collapse characteristics which be quite different from those of perfectly closed sections. Hat shaped section members were tested at the impact collapse velocities of 4.72m/sec, 6.54m/sec and 7.1m/sec and double hat shaped section members were tested at the impact collapse velocities of 6.54m/sec, 7.1 m/sec and 7.27m/sec.

Session Initiation Protocol (SIP) has become the call control protocol of choice for Voice over IP (VoIP) networks because of its open and extensible nature. However, the integrity of call signaling between sites is of utmost importance, and SIP is vulnerable to attackers when left unprotected. Currently a hop-by-hop security model is prevalent, wherein intermediaries forward a request towards the destination user agent server (UAS) without a user agent client (UAC) knowing whether or not the intermediary behaved in a trusted manner. This paper presents an integrated security model for SIP-based VoIP network by combining hop-by-hop security and end-to-end security.

This paper tries to define the characteristics of windows frame built in the end of Koryu dynasty to the early period of Chosun dynasty. The windows frame is found both in temples and in Maeng's house. It is thus proved that the frame was a general one prevailed in that time without regard to function and region. And it proves to be the original form of windows frame of temples and houses in the middle or the end of Chosun dynasty.

It is true that early Chosun's sports meeting was influenced by Japan and the West. However, the positive nature of Chosun's sports meeting development cannot be underestimated just because it was influenced by the outsiders. It is remarkable achievement for those enlightened people at those time to promote and influenced Korean people to strengthened their nationalistic and patriotic spirit through sports meetings.

The mobile agent paradigm can be exploited in a variety of ways, ranging from low-level system administration tasks to middle ware to user-level applications. Mobile agents can be useful in building middle-ware services such as active mail systems, distributed collaboration systems, etc. An active mail message is a program that interacts with its recipient using a multimedia interface, and adapts the interaction session based on the recipient's responses. The mobile agent paradigm is well suitable to this type of application, since it can carry a sender-defined session protocol along with the multimedia message. Mobile agent communication is possible via method invocation on virtual references. Agents can make synchronous, one-way, or future-reply type invocations. Multicasting is possible, since agents can be aggregated hierarchically into groups. A simple check-pointing facility has also been implemented. Another proposed solution is to use multi agent computer systems to access, filter, evaluate, and integrate this information. We will present the overall architectural framework, our agent design commitments, and agent architecture to enable the above characteristics. Besides, the each information needed a mobile agent system such as text, graphic, image, audio and video etc, constructed a great capacity multimedia database system. However, they have problems in establishing connections over multiple subnetworks, such as no end-to-end connections, transmission delay due to ATM address resolution, no QoS protocols. We propose a new connection management scheme in the thesis to improve the connection management involved of mobile agent systems.
