The wide spread of Internet and rapid development of e-commerce-related technology have brought sweeping changes on the traditional commercial transactions. Accordingly, many efforts to transform these transactions electronically under e-commerce environment have been carried out. As most transactions are usually made through negotiations, the function of automated negotiation is also required in the e-commerce environment. This paper aims to develop the method to generate and evaluate the multi-attribute negotiation proposals for automated negotiation systems. To this end the related articles are reviewed and the method dealing with e-negotiation strategy is suggested. In this method, the seller generates his or her own negotiation proposal and then evaluates the buyer's proposal based on SAW (Simple Additive Weighting Method), one of the MADM (Multi Attribute Decision Making) methods. To verify the suggested method, a case study is conducted in the order-based manufacturing environment.

Recently there are many changes of logistics environment Such as integrated logistics information system, the rapid growth of the domestic and international small package express service and third party logistics with Electronic Commerce. At this time it is very important to deliver to customers the goods sold through EC speedy, accurately and safely. That is to say, the role of small package express service is very important at EC times. The bottlenecks of small package express service in the circumstances of EC are the weakness of EC operating company and small package express service provider the shortage of distribution centre and cargo terminal, the shortage of skilled man with related small package express service etc. So, I suggested that for activation of EC it is necessary to strengthen the strategic alliances, introduce GPS and use the third party logistics positively in the side of small package express service provider. And it is necessary to prepare for the settlements of traffic problems, support the introduction of integrated logistics service, logistics information system, deregulate restriction such as weight limit of vehicles in the side of the government. And to government support throughout extending nation's SOC, deregulation, support to small package express service terminal, permit to stopping & parking in downtown, abolishing a no passing zone, permit to being employed foreigner. Also this service involves ensuring that the product will arrive when wanted, and in an undamaged condition.

Video information is an important component of multimedia systems such as Digital Library, World-Wide Web (WWW), and Video-On-Demand (VOD) service system. Video information has hierarchical document structure inherently, so it is named "structure video document" in this paper. This paper proposes a data model, a query language, and an indexing scheme for structured video documents in order to store, retrieve, and share video documents efficiently. In representing structured video documents, the object-oriented data modeling technique is used since the hierarchical structure information can be modeled as complex objects. We also define object types for the structure information. Our query language supports not only content-based retrieval, which means the queries based on the structure of video documents, and spatial/temporal relation for video documents. In order to perform structure queries efficiently, as well as to reduce the storage overhead of indices, an optimized inverted index structure is proposed.

In order to distinguish the genetic polymorphism among the olive flounder (Paralichthys olivaceus) obtained from East sea of Jumunjin, aquaculture of Tongyoung and Geoje, and East sea of North Korea, the ND-4 and cytochrome b genes of olive flounder were divided into 5 regions. Each region was analyzed by degenerating gel electrophoresis scanning (DGES), and by subsequent DNA sequencing. The DGES disclosed characteristic DNA polymorphisms in ND-4-2 and ND-4-3 regions of olive flounder, which were also confirmed by the DNA sequencing. The olive flounders obtained from the different marine areas showed DNA mutations in ND-4-2 region (G390A, C402T, and A411G； GenBank： AB028664), and also showed frequent DNA mutations in ND-4-3 region (C515G, C537T, C538T, A567G, G714A, C736T, G756A, A759T, T817C, and T829G), white the cytochrome b gene showed no DNA mutation both in the DGES and DNA sequencing. These data suggest that the ND-4-2 and ND-4-3 regions are candidate loci to distinguish the origin of olive flounder, and that the DGES used in this study provided fast and reliable informations for the genetic polymorphism.

This study explores the possibility of innovative government's administrative services to the public by reflecting the social implications of 'Big Data'. In particular, the idea of OPP (Order Penetration Point) and SOP (Service Offering Point) as a management scheme for the extension of administrative processes into the resident's living space is proposed to overcome the inherent limits of e-government service quality, the root cause of which is believed in the segregation of two spaces - the resident's living space and the government's offices. Furthermore, a discussion is made on how to integrate sensor data from the resident's living space with traditional administrative database, which is a new challenge in the course of synchronizing the two spaces. The implications on the process extension are also provided centering around the shift from reactive to proactive services.

In this study, we consider a capacity planning problem where the number of machines at each workstation is determined in manufacturing systems of top-edge electronic products such as semiconductor or display. The considered manufacturing system is the typical hybrid flowshop which has identical parallel machines at each workstation and the setup operation occurs when the types of consecutively processed products are different. The objective of the problem is finding good combinations of the numbers of machines at all workstations, under the given capital amount for purchasing machines. Various heuristic methods for determining the numbers of machines at workstations are proposed and the performances were tested through a series of computational experiments. In the study, a simulation model has been developed in order to simulate the considered manufacturing system with dynamic orders and complex process. The simulation model is also used for conducting the computational comparison test among various proposed methods.
