Fictitious notch radius approach is based on the Neuter's microstructural support hypothesis which assumes that fatigue crack is governed by highly stressed volume of the material right on the weld toe area rather than the surface stress at a pin point of weld toe area. Variety of successes have been achieved in applying this methodology to the fatigue of welded joint, hence, it became one of recommended design procedure in IIW's recommendation as well as many ship classification societies. 1mm fictitious notch radius approach was applied to the various fatigue problems of welded joints in this study covering the effect of weld size, notch stress calculation for 3D geometry and low cycle fatigue problem. It was found that fictitious notch radius approach fumed out to be very effective and accurate in dealing with fatigue strength of welded joint.

There is no doubt that agents play an increasingly predominant role in e-commerce, whether these are business-to-consumer or business-to-business applications. However most of the current e-commerce agents only support a single bid for a product at a fixed price. Although price is an important factor, it is not the only concern of both business and consumer. There is doubt as to whether such agents satisfv both parties. Negotiation on a variety of issues is needed in order to reach an agreement. In this paper, a computational agent negotiation(CAN) model is proposed to facilitate multiple-issue negotiation via an agent. The main contribution of the CAN model is it enables agent to participate actively in the negotiation with various feedback instead of simply an agreement or rejection.

Currently, the consumer pattern is directed to small quantity and high variety these days. World market is led by technological innovations and changes rapidly. To survive in this environment, the raising of small and medium enterprises is highly desirable. In the context of nationwide restructuring, competitive medium and small industries which are in good financial status should lead the nation's economy. But general ignorance of the safety issues could lead to a miss management of this industry in this field. In this study, actual condition and improvement of safety management are as follows; We have to 1) find out the factors which endangers this industry, and set a proper guideline for safety management. 2) encourage safety management of these industries by themselves, and advertise and provide technical support for using PC and internet. 3) set a higher standard of safety issue when accrediting a prospective medium and small industry, and have a firm control of this issue once accredited. 4) supply more governmental financial aids to terms of safety issues for medium and small industries.

Broadband networks are designed to support a wide variety of services with different traffic characteristics and demands for Quality of Services. Bandwidth allocation methods can be classified into two major categories： static and dynamic. In static allocation, bandwidth is allocated only at call setup time and the allocated bandwidth is maintained during a session. In dynamic allocation, the allocated bandwidth is negotiated during a session. The purpose of this paper is to develop policies for deciding and for adjusting the amount of bandwidth requested for a best effort connection over such as ATM networks.. This method is to develop such policies that a good trade off between utilization and latency using cell delay variation to the forecast the incoming traffic in the next period. The performances of the different polices are compared by simulations.

Cim realization for the machinery manufacturing plant has several problems such as a lack of the adaptibity for system integration of the production machines, a lack of the flexibility for the information flow and a lack of the interchangeability fot the variety of the interchange information. In the paper the development of VMD for the object oriented machine tool in Cim enviroment is accomplised. FOr this purpose VMD is constructed in PC with NT 3.51/OS enviroment by using the exculsive comunication board and PLC for the conventional CNC machine tool that VMD support is not available. And also RS232 interface between VMD and CNC's and DNC 2 comunication board supplied by FANUC for two types of CNC are used. This developed VMD is very useful for CIM construction in the shop floor having the multi-vendor CNC controllers.

The results of this theis are as follows. As regards the chronological transformation of the royal court dancing which is characterized by the variousness and colorfulness of the old-fashioned dancing suit, in the pre-dynasty of triple alliance among Shinla, Bakjae, and Goguryeo, the traditional ritual stood on ceremony through the ceremonial dancing in support of a religional rite. But while the Shinla, Bakjae, and GoGuRyeo dynasty began to excercise the systematic royal control over people, each royal court employed the professional ritual dancers; and it encouraged them to dance on the variety of ceremony on behalf of a rite and celebration. Of course, except for that of Shinla dynasty, it is not so easy to find out the historical record for the evidence which can back up these facts. As representatives of a ritual dancing, the religional ceremony of Shinla dynasty brought about the orientation of GumGee-Mu, MooAe-Mu, Saseon-Mu, Seonyu-Ak, and Cheoyong-Mu.

Video copy detection methods have emerged in recent years for a variety of applications. However, the lack of efficiency in the usual retrieval systems restricts their use. In this paper, we propose a parallel implementation strategy for content based video copy detection (CBCD) by using a multi-core processor. This strategy can support video copy detection effectively, and the processing time tends to decrease linearly as the number of processors increases. Experiments have shown that our approach is successful in speeding up computation and as well as in keeping the performance.
