Pmart(Pukyong-mart)는 지능형 멀티 에이전트에 바탕을 두고 가격, 상품의 특성, 보장 기간, 서비스 정책 등에 대해서 협상을 벌이는 에이전트 중재에 의한 전자상거래 프레임워크이다. Pmart는 협상 알고리즘, 에이전트 시스템, 웹 서버로 구성되어 판매자 및 구매자 모두 만족할만한 성공적인 거래를 제공하지만 단일 시스템 내에서의 Pmart 서비스는 다양한 거래자를 선택할 수 없다. 본 논문에서는 이러한 Pmart의 단점을 보완한 분산 Pmart 시스템을 제안하고, 이를 위하여 이동 에이전트의 보안 및 전자지불 기능이 추가된 확장 Pmart를 설계한다. 또한 분산된 Pmart 구성에 필요한 XML과 전자서명에 기반한 안전한 이동 에이전트 시스템을 제안한다.

The Purpose of this study is to establish efficient and balanced development and to make transparent marketing system, environment which is to protect small business, consumer's. This Goal of this study is that focus on development of regional and national economy. Especially, to protect small businessmen, to reserve consumer's buying choice. First of all, to examine causes of distribution maintenance and to will be analysed legal controversy of big distributive markets since local autonomy business limits. It is this study that concentrate on big distributive mart shutdown of business hours, Problems and Countermeasures. The main focus of in this study is as follows: First, to examine the ruling of the court that protest and accept of business hour in big distributive mart' problem and regulation, Second, to understand each of the judgement and problems of distributive shutdown systems, Third, to suggest the good distributive business trade act and the possible collaboration with focus on small and big mart System in Korea. This paper to analyze case of conflict and focus on establishment of transparent distribution since business limits.

Inventory Management has become a very important issue in supply chain management, because inventories may be used as a means to accomplish the certain strategic goals in company decisions. RFID(radio frequency identification) technology is used to help manage inventories. It is known that the ideal control of inventories is to replenish item by item. This paper points out several misinterpretations from the Wal-mart report presented in '07 Seoul Forum and suggests the new direction of RFID application. In this paper we consider RFID as not 'identification technology' but 'information technology.' The 'RF-Kanban' suggested here is adopted from the'Kanban'concept of TPS(Toyota Production System). The RF-Kanban system shows the easier control for replenishing various items in boxes. Lots of inventories can be reduced through RF-Kanban System. This work develops the protocol of RF-Kanban and introduces the case study for easier understanding.

Insurance system has a lot of decision factors which are affected by the kinds of insurance products. and has the features of many exceptions. Since in applying the product attributes to the current system the value definition through tables and the exception treatment logic (if then else) are used in parallel, the cost of a product change and a new product development becomes increased and the prompt market reaction is difficult. In this paper, we propose the well formed rule base system which makes data for the business logic of insurance attributes and discuss the benefit of application of this system to the real project.

Many traditional retailers are losing money due to loss and accidents in managing their carts. Therefore, we intend to solve these problems by installing a raspberry pie with various functions in order to efficiently manage the cart. First, use ultrasonic sensors to measure the distance between the cart and the object, use vibration sensors to vary the number of vibration sensors, change the number of vibrations to the user, and use Beacon to transmit the cart in real time. It also contributes to consumers' spending patterns and revenue generation by identifying consumers' consumption patterns. Problems with lost are also resolved by issuing an audible warning (outside of Mart) if a distance is removed (outside of Mart).

Structures with soft story irregularity have been seriously damaged in earthquakes. Therefore, the analysis of dynamic behavior of structures with soft story irregularity is of great value and relevance. In this study, a certain method will be used to discover the displacements and internal forces and to find out results about soft story irregularity. For this study, the multi-story frame-hinged shear wall system has been used as a model according to the continuous calculation system. The dynamic characteristics of the system have been obtained by analyzing the governing differential equation of the system. The dynamic characteristics have been calculated for a practical and quick analysis as indicated in tables. The suggested method is wholly based on manual calculation. A spectral analysis can be easily conducted with the help of Tables provided by this study. A sample has been solved and compared to the finite elements method to study the suitability of the method suggested at the end of this study.

In the form of B2C transaction, making an on-line order by using the website increases rapidly. An off-line order at the whole sale outlets is geometrically increasing. However, it is so true that both types of market are showing a tendency to become computerization. As to apply this type of computerized B2B transaction to this kind of large scale wholesale outlets, the most important fact to be considered is that there must have no data error. In addition to this, an accurate counting of actual stock is a precondition to decide a suitable amount of production and a timely delivery of goods. In this study, reducing elements of the risk that may create a difference In between actual stock and that in the computer, the integrated B2B ordering system is designed by taking actual cases an example in order to manage the information for a sale, which is conducted by various system in the large scale wholesale outlets such as E-mart, Carefour or the same kinds.

Information technology is an important driving force that has changed consumer information environments. In order to adjust in the new environments, consumers need an innovative information system. The purpose of this study was to develop a Consumer Information System (CIS). CIS is a device that supports consumer's decision-making process and elevates consumer information competence. The CIS was constructed by the following steps: (1) organization of developers, (2) systematization of consumer information, (3) data loading, (4) integration of consumer database: data warehouse, (5) data distribution, (6) composition of data mart, (7) use of data access tools: data-mining, OLAP, statistical analysis, Q+R, (8) data visualization: web server.
