Class extraction of object or component based software development methodology is the major factor for software quality. Each method has the class definition and extraction method however there are some troubles when the beginners try. Especially, the conceptual gap results to make the class extraction hard. This research suggests three diagrams to support it. They are Information diagram, Behavio diagram and Management diagram. They specify which services a stakeholder wants, which information to support the service, which actions to solve the service and who has the responsibility for those. Any analysis process which takes class extraction can utilize these diagrams.

A single line diagram is a graphic user interface to represent electrical connectivity between power equipments in distribution automation systems. This paper proposes a new single line auto-drawing technique based on the service oriented architecture. Web service, CIM(Common Information Model) and SVG(Scalable Vector Graphics) are adopted to implement SOA concept. A web service demo system was established which is configured with the service provider, consumer and broker to verify the feasibility of this study.

Depending on point of view, a service can be defined as interactions between customers and service providers or service delivery processes or customer's experiences. To develop and design a new service, the most of approaches presented in the previous researches represent a service mainly by the interactive activities or functions between customers and providers. The critical features of services which differentiate services from physical products are the inseparability that production and consumption occur at the same time and the heterogeneity that each customer ask their requirements to providers. To reflect the characteristics on the service model, we have to include contextual features in the service model. For the purpose, we define a service as the process of solving the customer's problems and a service is structured into three components: contacts, informations, and activities. We suggest the job mapping diagram to model a service process by the three components and then apply it to a hotel service process and compare the result with it of a blueprint.

Purpose: This paper proposes S-NS diagram. S-NS diagram helps us find core factors which improve customer satisfaction. Methods: S-NS diagram draws a scatter diagram based on marks obtained from surveys consisting of several questions on satisfaction and non-satisfaction at the same time. S-NS diagram is divided into the 4 regions. We focused on region B which is High satisfaction and high non-satisfaction shown in S-NS diagram. Region B is the areas for needs to improve. Results: S-NS diagram can find few important factors which affect customer satisfaction. We improve Lecture Satisfaction using S-NS Diagram. Conclusion: S-NS diagram has been proven to be an effective method for improving customer satisfaction with a lecture satisfaction improvement example. We know S-NS diagram can use many fields including manufacture and service areas.

The purpose of this article is to set up the scientific and reasonable norm of location and service area determination instead of the pro-administrative lacking availability, so as to propose more practical and reasonable standard of space unit for the location of facilities. This article has accepted the method of Voronoi Diagram as a new scientific and reasonable criteria. The article chooses and realizes a model that can propose a new service area, transform and apply to improve its reality, and assesses which has more reality and compatibility by comparing the models. The result from this procedure can be adapted in objectification of the service area determination and formation of the standard space unit.

In this paper, we consider the problem of regrouping a number of service sites into a smaller number of service sites called centers. Each service site is represented as a point in the plane and has an associated value of service demand. We aim to group the sites so that each group has the balanced service demand and the sum of distances from the sites in the group to their corresponding center is minimized. To solve this problem, we propose a hybrid genetic algorithm that is combined with Voronoi diagrams. We provide a variety of experimental results by changing the weights of the two factors: service demands and distances. Our hybrid algorithm finds better solutions in a shorter computation time in comparison with a pure genetic algorithm.

We present in this paper the methodology for automatic generation of OWL-S service model ontology along with the results and issues. First, we extract information related to atomic services and their properties such as IOPE from the UML class diagram, and retrieve information related to the composition of services from the UML state-chart diagram. Then, the XSLT applications utilize the acquired information to generate the OWL-S service model ontology through the predefined mappings between OWL-S constructs for composite services and UML state-chart primitives. For the justification of generated service ontology, several validation checks are performed. Our service ontology generation method is general and fully automatic, as well as effective, in that it is achieved in an environment familiar to developers, and information needed to generate service ontology is provided necessarily during service development. It is also noticeable to facilitate representing the condition with GUI rather than a complex language such as OCL.

The internet call systems using CTI(Computer Telephony Integration) functions are designed with system configuration, DFD(Data Flow Diagram) and ERD(Entity Relationship Diagram) in this paper. The internet call systems are constructed to cooperate with conventional CTI call center. The internet phone calls occurred from the web browser of customer can be connected throughout VoIP gateway and PBX to many counselors. The internet call systems can provide various services; customer information service, escorted browsing service, text chatting service, text sharing service, conference service, and statistical analysis service.

Distribution Automation System(DAS) is designed to improve operational efficiency by acquisition and control of remote data using its components such as central computation units, communication network and feeder remote terminal units. A conventional human machine interface of the DAS adopts a schematic diagram which is made by drawing power equipments on the geographic information system map. The single line diagram is more useful than the schematic diagram for the main tasks of distribution system operation such as protective relay coordination, service restoration and loss minimization. Since the configuration of the distribution line is changed according to the relocation of the open tie switches, the auto-drawing algorithm based on the connection between the sections and the switches is an essential technique. This paper proposes a new auto-drawing algorithm for a single line diagram of distribution systems based on tertiary tree and collision avoidance method. The feasibility of the proposed algorithm has been testified for various cases using practical distribution system with 12 feeders.

This paper defines a diagram showing the characteristics of service connections in SOA, and it designs the connection testing with the diagram. The detail steps of building test requirements in the test design phase are explained, and the steps are applied to two different enterprise cases as examples. The cases are real SOA system of real enterprises. Recently, many enterprises have been trying to reconfigure their system as SOA systems. However, these projects are hard to be applied to their mission-critical real systems, since there is few testing technique understanding SOA characteristics, One of the missing characteristics of SOA in testing is that SOA needs a layering systems between business processes and applications. This paper focuses on the layering system of SOA to solve the testing problem in SOA.
