Many theorists have been asserting the advantageous of jikmeip system and disadvantageous of tukjeongmeip system in terms of competitiveness enhancement. But, department store is a business status where service is emphasized instead of price, it is advantageous to secure service competitiveness rather than price competitiveness. Therefore, by utilizing the professional merchandisers of the supplier even without having its own, the department store will keep the advantageous stand unless it is not a large buying system. Due to many items under control, distribution companies usually have limited source of professional merchandiser for each product. Thus, no matter how the importance of MD has been forced, when considering the practical situation, the tukjeongmeip will always have the competitiveness over the jikmeip.

In recent years, it has been a worldwide trend that many power utilities gave their attention to develop and operate their power plants, substation and distribution systems. Following this trend, KEPCO(Korea Electric Power Corporation) has developed many electric automation systems with various communication networks. It has been natural that the automation systems are just focused on to remote devices when they come to be designed. But, we have to shift the focus to the automation system itself. We have developed the Multi-service Optical Transmission System (M-OTS) for electrical power systems. It can be adopt to not only distribution power field but also the transmission power field. The result strongly shows that the system is potentially beneficial in reliability, speed, and expandability. This paper presents some of initial design efforts and results toward a KEPCO's communication system in distribution areas.

As the convergence between the conventional physical systems and IT computing resource is increased, the new paradigm of embedded system called Cyber Physical System (CPS) emerged. CPSs have many sensors, actuators and computing devices to understand and to control the physical system. As these all components are tightly coupled each other, standardized middleware such as Data Distribution Service (DDS) is considered to be deployed. But DDS takes too long time to discover each other in the large-scal CPS environment and has not precise specification of its execution architecture to provide efficient data exchange. In this paper, we design the efficient DDS architecture for development with interoperability to provide the high reliable data distribution. in real-time and propose the communication entity discovery procedure.

Seasonal incident rates were examined from the 981 pigs slaushtered in southern Kang-won and distribution of lesions and histopathological examination were conducted from 231 Enzootic pneumonia affected lungs. The results obtained were summarized as follows： 1. 39.7∼50.2% of 981 slaughtered pigs showed pneumonia lesions without seasonal variation and the incidence rate of Enzootic pneumonia was 23.5% 2. The distribution of Lesions of Enzootic pneumonia lobes was observed. The right lobes were affected more frequently than the left, and the highest frequency of 79.7% being recorded in the right cardiac lobe followed by the left cardiac, right apical, intermediate, left apical, right diaphrogmatic and diaphrogmatic. 3. In histopatological observation lung lobes were forming Iymphonodulus from perivascular, peribronchiolar Iymphoid hyerplasia and it was remarkable to bronchostenosis.

Recently the recongnition of Logistics becomes important to enterpries as a means for improving their competition, but the Korea enterpries falls for far behind in management techniques for analyzing realities and problems in the Logistics compare to the advanced countries. Especially the function of inventory control which is most undeveloped in them should be improved in Korea. Inventory is very important in Logistics, but there exists trade-off between inventory level and customer in the service level. It is difficult to coordinate both the reduction in the inventory level and the enhancement in the service level. Its effective technique is a DRP system. In general, it deals with arborescent distribution network in which a given channel member has a single source of supply. This article aims to present a DRP system, and more a DRP system which is flexible and responsive in the multisourcing, multi-echelon distribution network. Related research issues are discussed. Finally, using a DRP system on logistics and the management performance. So we can help the physical distribution improvement of the Korean enterprises.

The EU holds about 50% of exports and imports in the world trade of services. The insurance markets have undergone a significant consolidation in solvency rule, cross-border registration, and standardized accounts. In the EU-Korea FTA negotiations the EU is interested in mutual certification of qualifications as well as market liberalization of law, finance and distribution and so forth. When the negotiation with respect to the mutual certification of qualifications comes to a settlement, the two countries will drive it in service areas. Korea should examine european certification regulations and improve domestic insurance-related institutions. France is the focal country of the EU. The paper provides a comparative study of insurance markets and agents in France and Korea. The paper argues that Korea should initiate institutional changes and be transformed into an insurance service exporting country for the specialized insurance agents to move to EU countries.

Purpose: In this paper, the minimal repair-replacement warranty policy is used to carry out a warranty cost analysis with warranty servicing times and failure times that are statistically correlated to bivariate distributions. Methods: Based on the developed approach by Park and Pham (2012a), we investigate the property of the Freund's bivariate exponential distribution and obtain the number of warranty services using the field data to conduct the warranty cost analysis. Results: Maximum likelihood estimates are presented to estimate the parameters and the warranty model is investigated using a Freund's bivariate exponential distribution. A numerical example is discussed to deal with the applicability of the developed approach in the paper. Conclusion: A novel approach of analyzing the warranty cost is proposed for a product in which failure times and warranty servicing times are used simultaneously to investigate the eligibility of a warranty claim.

The Enterprise Service Bus based on Java Business Integration is an web service standard and one of the methods for implementing distribution channels of Service Oriented Architecture. Consisting of open source group, extensive venders and users, the ESB based JBI has the problems of ineffectiveness as well as advantages of extensibility of service plug-in. That is, in case users need to use Service plug-in, manual connection of packaging process and sequential distribution method is required. This study, therefore, proposes as a way of trouble-shooting the user-oriented component deployment tool which can manage entire process for deploying The ESB middleware platform to Service unit. At the same time, this study elicited the requirements based on issues of JBI-based ESB and has developed the modeling property, packaging, distribution and evaluation thru Schema analysis of JBI-compatible component. Using the deployment tool this study proposed, users will be able to perform and manage the whole deploying process without additional manual work for connecting component. Not only it is expected that interface based on Graphic User Interface provide usability and convenience but they can also minimize the errors rate through component and route validity verification function provided in deployment tool.

Because the structure of the economy is being changed from product-oriented and company-centered economy to service-oriented and customer-centered economy, and the market competition is varying with the competition of non-price factors, the importance for customer service of logistics system is being increased. Thus, the level of customer service should be represented as an element of the logistics decision and the facility location decision. The level of customer service provided by logistics system has an effect on customers\` purchase decisions, hence on the market demand. That is, the market demand is elastic for customer service as it is influenced by product price. Considering the effect of customer service on demand, this study develops the market area which each facility will serve. That area is circular, and distance norm is considered Euclidean and Rectilinear (or Manhattan) distance norm. The market demand for product at a particular area is affected by the level of customer service that facility provides, and the relationship between the market demand and the level of customer service is represented with a mathematical function.
