This paper presents an enhanced web-based distributed system with Single Access Object Protocol(SOAP), which uses HTTP as a communication protocol and XML as a data presentation. The suggested system is applied into a Generic Equipment Model (GEM) for exchanging specified messages(SECS-II), which are encoded into XML presentation, between Equipment and Host via the web sorrel. In this paper, the designed system architecture and its soap components are presented.

Today, XML is widely used to present structured data and its importance has been expanded much in the web environment. Generally, we exchange XML documents to process XML-based data in distributed processing environments like a CORBA. But we need to configure CORBA environments to process XML documents. The system that has initially been designed to process XML is required. If there is no such system, we should configure most parts of the system, namely, IDL definition and CORBA client, CORBA server, implementation objects. In this paper, we propose a system that can apply an integration structure of web environment and CORBA without any additional configuration. Our proposed system can support various service types, namely, Also it can offer extensibility to legacy system with CORBA by using servlet and SOAP. Our proposed system can extend the structure to integrate XML with CORBA, Hence the web platform environment that applies this architecture can support much easier integration with CORBA environment.

Recently, RESTful web service is getting attention with the emergence of Web 2.0. The main advantages of REST web services are lightweight and easy implementation compared to SOAP based web services. In order to define and describe RESTful APIs, various methods have proposed. WSDL 2.0 can describe both SOAP-based and RESTful services and but it is too complicated. WADL is championed by Sun Microsystems and it is lightweight, easier to understand and easier to write than WSDL. The purpose of WADL is to allow web services to be described in a machine readable way, to make it easy to create Web 2.0 applications and create a dynamic way of creating and configuring services. However, WADL does not provide utility tools to generate client code automatically and the developers describe client code manually. In this paper, we design and implement a WADL2Stub system to generate client code from WADL files automatically so that the developers use REST web services to easily and conveniently.

The effect of fatty acid content in oily soil and conditions of washing on the removal of triglyceride have been studied. Cotton lawn was soiled with the four-component soil-tripalmitin, palmitic acid, dodecyl alcohol and dodecane-and washed in constant temperature waterbath shaker. The detergency was estimated by analysis of triglyceride labelled carbon-14 on fabrics before and after washing by means of liquid scintillation counting. It was shown that the detergency of triglyceride washed with the nonionic, nonylphenol poly (10)-ethylene oxide and soap was increased steadily with increasing temperature, whereas with the anionics Na-DBS and SLS, the detergency was rather decreased when the temperature was elevated above $40^{\circ}C$. To investigate the effects of free fatty acid content in soil on the removal of triglyceride, the fabrics were soiled altering palmitic acid content, and then washed. From the results, the detergency of triglyceride was developed with increasing free fatty acid content. With soils containing less than $30\%$ of free fatty acid, of the three detergents tested, the nonionic was by far the most effective soil removal. Soap was intermediate and the synthetic anionic was the poorest. With soil containing $45\%$ of free fatty acid, soap was the most effective soil removal. When NaOH was added to detergent solution. the detergency of triglyceride was improved without regard to detergents. The optimum alkalinity was obtained according to free fatty acid content. And the alkalinity changed to low NaOH concentration with increasing free fatty acid content. From the results mentioned above, it could be concluded that the major removal mechanisms of triglyceride containing oily soil were mesomorphic phase formation, solubilization and soap forma-tion when alkali was added in detergent solution.

Recently, as wireless communication are becoming more and more popular, Internet users is becoming increasingly demand HTTP-based web service in mobile computing environment. But, overall performance of web services may slow down, because mobile device are generally equipped with lower capability. Therefore, the most important factor to design wireless internet delivery system should be scalable to handle a large scale traffic due to rapidly growing users. But, in case of some preceding research, they not present a basic efficiency reform measure until currently. Therefore, In this paper, We propose a Web Service Delivery System for mobile environment that alleviates problems that occurred while executing web services in mobile environment and are helpful to overcome the above needs. The system composed of HTML/WML Converter, SOAP message processor. We compare the existing system with the proposed system.

With the recent development of the ubiquitous computing technology, there are increasing interest and research in technologies such as sensors and RFID related to information recognition and location positioning in various ubiquitous fields. Especially, RTLS(Real-Time Locating Services) dealing with spatio-temporal data is emerging as a promising technology. For these reasons, the ISO/IEC published the RTLS standard specification for compatibility and interoperability in RTLS. Therefore, in this paper, we designed and implemented Spatio-temporal Query Processing Systems for efficiently managing and searching the incoming Spatio-temporal data stream of moving objects. Spatio-temporal Query Processing Systems's spatio-temporal middleware maintains interoperability among heterogeneous devices and guarantees data integrity in query processing through real time processing of unceasing spatio-temporal data streams and two way synchronization of spatio-temporal DBMSs. Web Server uses the SOAP(Simple Object Access Protocol) message between client and server for interoperability and translates client's SOAP message into CQL(Continuous Query Language) of the spatio-temporal middleware. Finally, this thesis proved the utility of the system by applying the spatio-temporal Query Processing Systems to a real-time Locating Services.

ETSI M2M Platforms provide general infra services for machine-to-machine communication. In this paper, we propose a service-level integration methodology which can integrate a ETSI M2M platform with heterogeneous web applications based on WSDL 2.0. Considered heterogeneous web applications are the ones that use SOAP, HTTP and CoAP protocols for inter-communication. The proposed WSDL 2.0-based service-level integration methodology includes the followings; (1) We present a method of how to describe standardized M2M platform service interfaces into a WSDL 2.0 document. (2) A proposed web client generator is used to generates SOAP, HTTP and CoAP client codes from the WDSL 2.0 document. (3) We propose protocol conversion proxies which translate protocols into other protocols in web service run-time.

본 연구에서는 하천공간정보의 웹서비스를 위해 SOAP(Simple Object Access Protocol) API 및 REST(Representation State Transfer) API로 제공하는 HydroG-OneFlow 웹서비스를 개발하였다. HydroG-OneFlow는 GML 기반의 서비스를 제공하며 GetBasin, GetGeoVariable 및 GetData 등의 기본서비스로 구성된다. GML은 GIS S/W의 벡터 GML 포맷과 공간정보 오픈플랫폼 서비스인 브이월드 데이터 API에서 제공하는 GML 포맷을 참고하여 하천공간 벡터정보를 제공할 수 있도록 GML을 구성하였다. GDM 공간 데이터에 대한 벡터정보 ML 수용 수준을 향상시킬 수 있도록 벡터구조의 점, 선, 면 정보에 대하여 GML의 PointPropertyType, CurvePropertyType, SurfacePropertyType을 도입하였다. 또한 일반적인 공간자료에서는 Multi 객체에 대한 지원도 필요하다. 현 GDM 데이터베이스에서도 OGC 표준의 MultiPoint, MultiLineString, MultiPolygon을 지원하고 있다. 이를 위하여 GML의 상응 요소인MultiPointPropertyType, MultiCurvePropertyType, MultiSurfacePropertyType을 하천공간정보 벡터 스키마에 도입하여 활용하였다. 클라이언트 서버 통신은 메시지 교환프로토콜인 SOAP을 사용하여 서버의 객체를 직접 호출하여 이루어진다. 서버는 서버의 제공 서비스를 WSDL(Web Service Description Language)를 통하여 게시하고 클라이언트는 이 기준(Criteria)을 참고하여 접근한다. GetData의 경우 Type(GRID or VECTOR), GDM(Geospatial Data Model) 여부(true or false), LayerName, BasinID, GenTime을 인자로 받아 GeoData에서 검색된 정보를 반환한다. SOAP버전은 1.1과 1.2를 지원하여 접근하는 클라이언트에서 선택할 수 있도록 개발하였다.

Web services are key applications in business­to-business, business-to-customer, and enterprise applications integration solutions. As the mobile internet becomes one of the main methods for information delivery, mobile Web Services are regarded as a critical aspect of e-business architecture. In this paper, we proposed a mobile Web Services middleware that converts conventional internet services into mobile Web services. We implemented a WSDL (Web Service Description Language) builder that converts HTML/XML into WSDL and a SAOP (Simple Object Access Protocol) message processor that performs SOAP message handling, chain and handling of server requests. The former minimizes the overhead cost of rebuilding mobile Web Services and enables seamless services between wired and wireless internet services. The latter enhances SOAP processing performance by eliminating the Servlet container (Tomcat), a required component of typical Web services implementation. Our main contributions are to overcome the latency problem of current Web Services and to provide an easy mobile Web service implementation. Our system can completely support standard Web Services protocol, minimizing communication overhead, message processing time, and server overload. Finally we compare our empirical results with those of typical Web Services.
