  • In this paper. we propose a novel performance monitoring scheme for heterogeneous SOAP nodes. The scheme is basically based on two-level (kernel-level and user-level) packet filtering of TCP flows. By TCP flow, we mean a sequence of raw packet streams on a TCP transaction. In this scheme, we detect and extract SOAP operations embedded in SOAP messages from TCP flows. Therefore, it becomes possible to monitor heterogeneous SOAP nodes deployed on diverse SOAP-based middlewares such as .Net and Apache AXIS. We present two implementation mechanisms for the proposed scheme. The first mechanism tries to identify SOAP operations by analyzing all fragmented SOAP messages on TCP flows. However, a naive policy would incur untolerable overhead since it needs to copy all packets from kernel to user space. The second mechanism overcomes this problem by selectively copying packets from kernel to user space. For selective copying, we use a kernel-level packet filtering method that makes use of some representative TCP flags.(e.g. SIN, FIN and PSH). In this mechanism, we can detect SOAP operations only from the last fragment of SOAP messages in most cases. Finally, we implement a SOAP monitoring system using a component ca]led SOAP Sniffer that realizes our proposed scheme, and show experimental results. We strongly believe that our system will play a vital role as a tool for various services such as transaction monitoring and load balancing among heterogeneous SOAP nodes.

  • SOAP using WSDL(Web Service Definition Language) was proposed for effective integration of distributed objects. But the SOAP message and WSDL document automatically generated from development tool are fully dependent on the development environments. So the dependency of SOAP messages and WSDL documents for objects to the development environment is still a big problem to be solved for the integration of heterogeneous distributed objects. In order to support integration of heterogeneous distributed object, we implemented SOAP Bridge called WBSB(WSDL Based SOAP Bridge). As service request message for a particular service object is translated into appropriate SOAP message for the selected service object by WBSB using WSDL repository, a client can use service object without considering the development environment of the service object.

  • SOAP is a protocol used for information exchange in distributed computing environment and SOAP defines mechanisms for message transferring between distributed system and remote procedure call/response process. This SOAP is able to be used independently on operating systems and program languages because it uses only a text-based XML for protocol. Therefor ebXML that is a standard for E-Commerce adopts SOAP for message exchange. In this paper, we developed Message Broker System based on SOAP. By this Message Broker System we can more easily exchange messages for B2B. Accordingly we can manage and integrate a lots of business partners.

  • Objective : We have reported the effects of Seosiokyongsan (SSOOS) cp soap on increasing skin moisture, decreasing pore size, and reducing acne symptoms on previous studies. But in the case of SSOOS soap, many soap bases were used in the making process. So we could not determine whether the above test results were the effect of soap bases or SSOOS herb medicine. Therefore, We conducted this clinical test to find out the effect of SSOOS itself. Methods : We made two kinds of soap. One type was made of cp soap using only soap bases and gave them to 10 subjects. The other type was cp soap made by adding SSOOS to the soap base and gave them to 25 subjects. The other 10 subjects did not limit the soap. Subjects were asked to wash their face with soap in the morning and evening for six weeks. The test was conducted three times and the results were compared and analyzed. Results : In the test group using the SSOOS soap, the oil in the U zone was significantly decreased and the moisture was significantly increased compared to other two control groups. Pores size and pigmentation were decreased but not significant. There was a significant increase in moisture in the soap base group, but that was a slight increase compared to SSOOS soap. There was no significant results in the without soap control group. Conclusion : SSOOS soap was found to have a significant effect on facial skin as cleansing products.

  • Distributed applications based on standards such as CORBA, DCOM, and EJB have been widely used in distributed environments. Recently, another XML-based standard, SOAP, has been recommended for web applications. However, these standards have a shortcoming in inter-operation because they can be run on their own environments. In this paper, we design and implement a SOAP bridge for inter-operation of SOAP with other distributed object standards. Its function is to map formats between SOAP and CORBA/DCOM at run time. Through performance experiments, we show that the computing overhead is small compared to the whole transaction execution time. Therefore, distributed objects of other platforms can be reused instead of developing new objects based on SOAP. Also, using the SOAP bridge, we design and implement an XML-based bidding system on the web. Because it is based on the web standards, it has advantages such as extendibility and interoperability compared to previous proprietary electronic commerce systems.

  • Web service implementations are now rapidly growing. Web services are easily achieved by XML messaging for most programming languages. Applications usually utilize web services through APIs tied to a specific implementation of SOAP. nML is a dialect of SML and OCaml made in ROPAS. The soaptype type in nML is defined for the value of SOAP encoding. SOAP encoding specification defines rules for serialization of a graph of typed objects using XML Schema. XML Schema validates XML SOAP value. The soaptype type is encoded to XML and decoded from XML. It is necessary to guarantee safe encoding and decoding. So, the definitions for element and type definition in XML Schema are specified by element type and typeinfo type, which include the part of the definitions of XML Schema specification.

  • 기존 분산객체시스템들은 복잡한 환경 설정.고가의 소프트웨어 구입 등의 문제로 활용에 제약을 받는다. 따라서, 최근에 구현이 쉽고, 표준화되어 있어 이러한 문제를 해결할 수 있는 분산 기술로 SOAP이 많은 관심을 받고있다. 그러나 이러한 분산 기술들은 각각의 표준 환경에서만 운용이 된다. 따라서 본 논문에서는 기존 분산객체시스템과 SOAP 기반 시스템의 상호 운용성을 높일 수 있는 SOAP 브리지를 설계한다. 그리고 SOAP 브리지의 성능 실험을 통해 기존 분산객체시스템과 SOAP 기반 시스템 연동에 성능 저하가 퍼지 않음을 보인다. 또한 이러한 SOAP 브리지를 활용하는 방안으로 대규모 분산시스템인 XML 기반 전자입찰시스템을 구현한다. 이 시스템은 XML과 SOAP 기반이므로, 기존 전자상거래 시스템이 갖는 표준화.확장성의 문제를 해결할 수 있다.

  • By introducing Web Services, distributed GIS services from different vendors can be dynamically integrated into a GIS application using the interoperable standard SOAP protocol. However, it is debatable whether SOAP can really meet the performance requirements of GIS. This paper presents an experimental evaluation of the performance of different SOAP variants: standard SOAP, SwA/MIME, and SOAP/MTOM. The objective of this paper is to demonstrate that SOAP performance in communicating large volumes of GIS data could be effectively improved by recent standards. Moreover, SOAP/MTOM is identified to be the fastest and the most efficient messaging protocol.

  • A recycling soap was prepared from non-cooking oils. The effects of physlcal and chemical properties of the recycling soap on biodegradation are expected to be different due to the thermal histories of the non-cooking oils. Therefore, the biodegradation rate of the recycling soap was studied by using Klebssella Pneumoniae(K. pneumoniae), and the growth rate of K. pnewoniae in soap solution was observed. The biodegradation rate of the recycling soap appeared to be slower as the thermal histories of the non-cooking oils became larger. This might be resulted from hydrolysis, in which the ester bonds in the oils are broken to produce hydroxyl group. It was also observed that the growth rate of the microorganism decreased with the increase in the thermal histories of the oils. As a result, it is desired that recycling soap should be produced from the non-cooking oils with the prober ranges of thermal histories to reduce water contamination. The non-cooking oils with larger thermal histories are considered to be recycling through the cracking process before used. Key Words : non-cooking oils, recycling soap, thermal history, biodegradation, microorganism growth.
