<item><title><![CDATA[Context Aware Semantic Service Discovery]]></title>
<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2277</link>
<description><![CDATA[The aim of service discovery is to discover services based on preferences given by service consumers. Many approaches are using keyword based syntactic methods and recent approaches are using semantic web technology to enhance service discovery. Traditional service discovery mechanism acts like a black box which processes input and gives output. Results of service discovery are not based on current situations. Real world is event driven and situations keep on changing in a dynamic manner. Situations affect service providers and service requesters. Hence, service discovery results should be situation aware. By introducing situation awareness (dynamic context) in service discovery, one can get relevant results. There is a need to maintain dynamically changing context of various services. This work proposes service discovery algorithm, which is based on rule engine. Implemented algorithm gives higher recall value and situation aware results while discovering services. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICES-0001/SERVICES-0001.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2281</link>
<description><![CDATA[A great deal of the achievement on model driven development and service-oriented architecture has been gained, but there are few tools for systematically supporting model driven development for service-oriented applications. This paper presents a model driven development platform for service-oriented applications. The paper first sets forth the architecture of the platform, and then discusses the infrastructure and implementation technologies of the platform in detail. On the basis of above work, the paper expatiates on a set of tools that constitute the platform and the relations between tools.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2282</link>
<description><![CDATA[The proliferation of software services on the Web can be seen as the primary wave of evolution in the internet age. As one of the most important services of the internet, email is used for business and personal communication. Email service providers (free or otherwise) still face a veritable administrative challenge with problems like spam mail, with the magnitude of this problem only increasing at a fearful rate. Managing the burgeoning volume and size of email has brought into picture issues like server uptime, optimal utilization of available resources, and storage discipline. These need to be addressed distinctly with new vigour. In this paper we present services with autonomic features which can be provided in an internet/intranet environment by setting thresholds, using e-mail reservoirs, and sharing/loaning e-mail storage space of designated users, and designation of such storage in user inboxes as overflow e-mailboxes. Services are also implementable as business methods where charges are made to users or e-mail providers who borrow space and credit given to those who lend space so as to enable a transparent, resilient and flexible mechanism to deal with the unpredictability associated with e-mail size and volume well within the precincts of total available storage space.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2284</link>
<description><![CDATA[Keyword-based search techniques are currently used to identify assets packaged for reuse. Unfortunately, these techniques are not suitable for searching large asset repositories, as they are known of having low precision and recall. One way to improve the search accuracy, is to identify reusable assets using their architecture models, since models based on similar architecture decisions, will most probably lead to developing similar solutions. However, informality and heterogeneity in designing architecture models remains a major obstacle for this identification approach. To overcome this problem, this paper proposes use of ebusiness patterns for reusable asset identification instead of architectural models. As ebusiness patterns are common to every designer, they could be used as an architecture design reference for comparing assets architecture layouts. Therefore, we propose a model to capture such architecture layouts in a machine understandable format using a graph of the adopted business,integration, and application e-business patterns, thereby assets could be rapidly identified based on the matching status of their architecture layout graphs. We believe the proposed approach provides better precision and recall when compared to unstructured keyword-based approaches <div><br><div align="left"></div><br><a href="http://www.servicescomputing.tv/rss/view/uploadfiles/2009\PPT\SERVICES-0005.ppt.\"  target=_black></a><br></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2286</link>
<description><![CDATA[Currently a large numbers of Web Services as well as other kinds of services such as EJBs, COM, and even Java Classes are published both externally and internally to an organization. Enabling SOA based system development by leveraging such kinds of services becomes a challenge. A semantically enhanced service repository which includes a service registry and a semantic service repository is put forward in this paper. The service registry manages the Web services, EJBs, and Java Classes by facilitating service registration, publishing, versioning, and monitoring. The details of the service model used in the registry are analyzed. Then the semantic service repository encapsulating the services with OWL-S is proposed. Later the ontology-based service discovery and matching method are introduced. The repository proposed in this paper can be used to manage the services and facilitate the service oriented application system development and integration.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2288</link>
<description><![CDATA[Providing services on Grid is becoming important these days, as there are several inter disciplinary collaborative projects which need an amalgam of services from diverse domains. However domain specific scientific programmers are still using traditional programming languages like Fortran and C to develop their applications and are quite unfamiliar with technologies such as Java and Web Services. The Automatic Grid Service Generator is a tool that helps a programmer to build Grid Services with ease. This paper brings out the complexities faced by programmers to write grid services on a heterogeneous grid and the design and implementation of the Automatic Grid Service Generator tool. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICE0007/SERVICE0007.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2290</link>
<description><![CDATA[Client requests often span over several web services and these services have to be invoked in some sequence based on business logic of a composite service. BPEL language is used for specification of web service composition and has become the industry standard. Unfortunately BPEL lacks sound formal semantics which leads to errors in service composition. It is therefore necessary to model and verify BPEL specification before execution. In this paper, we model certain BPEL activities using Coloured Petri-Nets (CPN). CPN is similar to Petri-Nets (PN) with an extra advantage that it has programmable elements. Our models are compact, yet feature-complete as compared to other models. Moreover, we propose an algorithm to identify structurally similar sub-parts of CPN model and replace them with a transition. The subpart replaced forms a separate CPN. This not only reduces the size of model but allows the sub-parts moved out to be verified independently. Further, we get a model of constant size when each subtask of an activity is same. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICES-0008/SERVICES-0008.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2291</link>
<description><![CDATA[The increasing demand of industry for enabling Business to Business and Application-to- Application communication has led to a growing requirement for Service Oriented Architecture. Web Services are based on Service Oriented Architecture which enable application-toapplication communication over the internet and easy accessibility to heterogeneous applications and devices. As web services proliferate and become more sophisticated and interdependent, the issues regarding their publication and discovery become of utmost importance. This paper proposes design of A Discovery cum Publishing Engine for web service discovery with refined searching mechanism which uses service rating techniques for efficient and effective web service discovery within optimum response time. We have used Data Mining Techniques to narrow down the search space in UBRs. Further the proposed engine has an ability to publish or search web service across multiple UBRs. In addition to this an extended design of service registry is proposed to store service rating data along with the service information. The Engine publishes the web services in UBR by following a classification scheme and performs a validation test on discovered web services. Service reviews and rating have been utilized to help a user for selection of appropriate service. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICES-0009/SERVICES-0009.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2292</link>
<description><![CDATA[Organizations and enterprises have to constantly re-engineer and customize business processes to stay competitive in their market. These modifications and customizations result in a large number of similar processes that lead to high costs of deployment and maintenance. This paper presents a multi-layer architecture for efficient management of process variations. The approach consists of organizing related processes into a Base layer and multiple Variation layers that separate the common fragment of the process from its customized parts. It avoids explosions of duplicate similar processes and allows business users flexible and easy change management of their processes. The implementation with the Eclipse modeling framework is also done to validate the proposed architecture. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICES-0010/SERVICES-0010.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<item><title><![CDATA[Extracting Environmental Information for Improved Web Service Matching and Identification]]></title>
<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2294</link>
<description><![CDATA[The current approaches to automatic identification of web services for a given set of requirements involve matching based on the interface information published by the service providers. However, due to concerns about exposing of internals of Web services, this information is typically limited, thus rendering Web service matching quite difficult in practice. In this paper, we argue that service matching can be significantly enhanced by harnessing the environmental information about the Web services. Towards this end, we explore two crucial questions: (i) what environmental information would improve service matching, and (ii) how much of that information can be revealed without violating the fundamental tenet of service-oriented architecture that the internal implementation details of Web services are not available to Web service consumers? This paper provides a precise characterization of environmental information of web services. We motivate our approach via real-life Web service search portals, by showing how environmental information can improve the precision and recall of service matching process. We then show how Web service providers can extract this information from the designs of the Web services, and publish them along with their interfaces. We illustrate our ideas with a realistic running example, and demonstrate it via a proof-ofconcept prototype. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICES-0011/SERVICES-0011.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2296</link>
<description><![CDATA[Task-based workflows describe a set of predefined tasks executed in a predefined sequence flow in which documents representing business objects are sent to activate tasks according to some business goal. The increasingly agile nature of business processes implies that neither the potential tasks nor their sequence flow can be defined a priori. In this context, documents may constitute the central abstraction in a business process execution while services are stateless entities. While business goals and associated business rules drive models and their executions, document content and its structure may additionally be used to determine how the document can be processed and how multiple processing tasks may be composed dynamically. This paper introduces a document-based workflow model that implements such agile business processes. The described approach relies on the use of a rule-based system as a means to capture diverse concerns such as business goals and associated rules within a uniform framework. To this end, we illustrate this approach with an electronic health record (EHR) application<div></div><div></div>]]></description>

<description><![CDATA[This work focuses on proposing a method of effectively dealing with P2P-based service selection and composition, especially when handling a large number of Peers along with their diverse qualities. The QoS-aware Peer selection is one of the major challenges faced in order to guarantee the success and enhance performance of distributed computing. Since many Peer candidates provide overlapping or identical functionalities, though with different QoS evaluations, selections need to be rapidly conducted to determine which Peers are suitable to join in the requested composite service. The main contribution of this paper is proposing a P2P-based service selection model, in which Peer&amp;rsquo;s non-functional properties are modeled with Web Service Modelling Ontology (WSMO), and where Ant Colony Optimisation (ACO) technique is adopted to facilitate and enhance the QoS-aware Peers&amp;rsquo; composition. We present experimental results to illustrate the effectiveness and feasibility of the proposed method.<div></div><div></div>]]></description>

<description><![CDATA[Services composition is a challenging research issue which comprises services composition and verification. Existing solutions focus on either composition or verification. In this paper, we propose such a complete solution using Temporal Logic of Actions (TLA). Firstly we model web services as automata, and use TLA to describe it; then generate composition proposals in a generic conceptual service set and verify it with TLC (a model checker of TLA). Given services composition proposals, we use signature and specification matching to select the proper services from service communities. The approach uses the idea of divide&amp;amp;conquer, which separates selecting services from the procedure of services composition. The experimental results demonstrate our approach is more effective than existing methods.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2302</link>
<description><![CDATA[Designing the adequate scope and granularity of services is critical for their effective reuse. Patterns at business process level are abstractions of common and reusable designs to operate businesses. Business Process (BP) patterns can capture expert process design knowledge and greatly benefit the design of new enterprise services by guiding the definition of their scope and granularity. Identifying pattern instances in real and large documented business processes is a challenging task, requiring the analysis of the structure, semantics and behaviour associated to process descriptions. In this paper1 we present a solution to identify BP patterns based on a graph matching mechanism. Structural and semantics aspects, including natural language processing, are addressed. The approach moves one step further to increase automation during the design of process-centric enterprise services. We demonstrate the approach, discuss its limitations, novelty and practical benefits by using a case study based on the National Revenue Agency case at SOPOSE08. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICES-0015/SERVICES-0015.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2304</link>
<description><![CDATA[The enterprise has historically been ambivalent about Social Computing. Although dynamic communities, collaboration, innovation, and the wisdom of crowds were recognized as valuable, doubts about content quality and standards frequently overshadowed the benefits that Social Computing had already demonstrated outside the enterprise.In this paper, we describe how we have been challenged to add governance to an existing enterprise wiki designed for capturing, collaborating on, and evolving best practice business process assets. With the addition of governance, our goal has been to transform a best practice process wiki into an authoritative source for process assets for the enterprise, a repository for registering usage, tracking variations, and linking process assets to one another and to other assets (e.g. accounts) and a vehicle for continual improvement of process assets through annotation, rating, and collaboration. The extensive scope of the content in this project dictates that both the creation and the governance of the content be distributed to the appropriate level of the community. It also requires functions to assist users with leveraging potentially significant amount of user feedback. Overall, the focus of the project has been on maintaining the quality of the content while fostering its continuous improvement and relevance to the community. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICES-0016/SERVICES-0016.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2307</link>
<description><![CDATA[Most of the organizations start BPM (Business Process Management) adoption at a small scale focusing on departmental initiatives and a specific process / process group and gradually bring more and more processes and parts of organization under BPM scope to scale up BPM adoption. This transition to &amp;lsquo;Enterprise level BPM&amp;rsquo; demands a different approach towards process centric solution delivery and presents new challenges and opportunities to organizations. &amp;lsquo;Process reuse&amp;rsquo; is identified as one such aspect of &amp;lsquo;Enterprise level BPM&amp;rsquo; that can greatly influence both the quality of process solution as well as ROI on them. Going beyond the existing process semantic and meta-model based approaches to process reuse, this paper explores a holistic process reuse model, covering multiple facets related to underlying business architecture, solution delivery process and organizational aspects.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2309</link>
<description><![CDATA[A lot of attention and discussion is centered on the requirements management for the first release of a BPM project. It is equally, if not more, important to realize that the BPM journey does not end with the single release and many of the requirements cannot be met in the first release. There has to be a plan and sufficient fore-thought to decide how the other requirements will be met in the subsequent releases. The requirements under discussion are not the ones which emerge out of the optimization of the process implemented in the current or previous releases but rather the ones which were left out during the previous releases. Also important from an end users perspective is to set the expectation as to which of the business process will be available in the new BPM application and the approach for business continuity in the transition phase. This article discusses the challenges and approach in managing the requirements across the multiple releases for a BPM engagement. A case study is used to explain how this was achieved for one the projects the author was involved in.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2314</link>
<description><![CDATA[In order to overcome the heterogeneities of different business document standards the United Nations Center for Trade Facilitation and Electronic Business (UN/CEFACT) has released the Core Components Technical Specification (CCTS). Core components are reusable building blocks for assembling business documents in an implementation neutral manner. However, core components are standardized without considering a specific implementation format and thus no tool integration is possible. Currently a syntax specific solution for core components, based on the Unified Modeling Language (UML), is provided with the UML Profile for Core Components (UPCC). In this paper we circumvent the complex UML meta model and provide a dedicated core component modeling environment based on a Domain Specific Language (DSL). Thereby, core component models are assembled on a conceptual level. In a next step the conceptual document model is used for the generation of domain specific artifacts. Our DSL based solution provides in situ validation of conceptual core component models and the flexible generation of deployment artifacts such as XML Schema definitions, used for the definition of interfaces in a service oriented environment.<div></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2315</link>
<description><![CDATA[In today&amp;rsquo;s business world, enterprises are not only using Web Services for implementing B2Bi. Instead, AS2 for realizing Internet based EDI, ebXML Messaging and even SMTP and FTP are used for exchanging business documents. Harmonizing B2Bi communication technology in a way that solely uses Web Services is barely an option for large enterprises as this would result in losing investments in existing IT systems. Moreover, forcing a specific communication technology upon all business partners is neither intended nor realistic in practice. At the same time, existing business document exchanges frequently only implement B2Bi scenarios partly. This paper focuses on a method for composing existing and new business document exchanges without replacing communication technology already in use. First, ebXML BPSS is proposed for describing the choreography of business document exchanges in a technology agnostic way. Second, ebXML CPPA is used to define messaging characteristics at the level of ebBP BusinessTransactions. Third, an integration architecture for performing ebXML BPSS choreographies using BPEL processes that execute each integration partner&amp;rsquo;s message exchanges is proposed. These BPEL processes assume Web service wrappers for reusing the functionality of messaging systems that are responsible for performing the actual business document exchanges and for providing sufficient status information to the caller. Different messaging systems then can be used for incorporating variable communication technologies in business collaborations. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICES-0018/SERVICES-0018.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2316</link>
<description><![CDATA[Electronic data interchange (EDI) is inevitable in enabling successful collaborations between different business partners. Exchanging information electronically requires standardized formats for information exchange. There exist a variety of standards including bottom-up standards as well as top-down standards. However, business partners may utilize different standards resulting in a loss of interoperability. To cope with the variety of standardized formats we propose the approach of mapping these formats to the common concept of core components introduced by the United Nations Center for Trade Facilitation and Electronic Business (UN/CEFACT). We evaluate the applicability of different strategies for mapping an arbitrary XML Schema based standard to core components by the example of ebInterface, an Austrian invoicing standard. The evaluation provides evidence that mapping of arbitrary standards to core components indeed provides substantial benefit in leveraging the interoperability between different business document standards. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICES-0019/SERVICES-0019.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<description><![CDATA[UN/CEFACT&amp;rsquo;s Modeling Methodology (UMM) is a modeling approach for describing the choreography of B2B processes. UMM is developed by the United Nations Center for Trade Facilitation and Electronic Business (UN/CEFACT) and currently defined as a UML profile. Thereby, it constrains the UML for the specific needs of B2B. As we learned, using UML as the underlying notation for UMM results in several shortcomings. Furthermore, some workarounds are required to fit the concepts of UMM to the UML meta model. Thus, in this paper we examine an alternative notation for UMM following the concepts of a domain-specific language (DSL). The contribution of this paper is twofold: (i) we identify general concepts for modeling global choreographies by taking UMM as a starting point. (ii) We introduce the Business Choreography Language (BCL), a domain-specific language designed to efficiently support the prior identified concepts. The concepts of the BCL are exemplified by an implementation using the Microsoft DSL Tools for Visual Studio. In fact, the BCL is an approach tailored to support the specific needs of global B2B choreographies. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICES-0020/SERVICES-0020.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2319</link>
<description><![CDATA[Many companies offer physical products combined with on-line services. For example, product configuration, ordering, order tracking, and payments can be done on-line. The service part of the total offering (the composition) is typically composed of services offered by providers where performance of both the composition (provided by the company) and the input services (obtained from providers) is governed by service level agreements (SLAs). The goal of our approach is to diagnose the performance of an on-line service composition in terms of the performance of on-line input services, with respect to the performance indicators mentioned in the SLAs, and to do this in real-time. Classical SLA monitoring techniques are batch-oriented and are not usable in the highly dynamic environment of Web service provision, where provider relations may change even during service delivery. Our techniques use real-time analysis of log files to trace and diagnose performance onthe- fly. Current Web service monitoring techniques do not relate a composite service to its components, as needed to provide diagnostic information. Furthermore, current approaches do not take into account that the dependency of a composition on its components varies for different attributes (such as cost and response time). In this paper we propose to extend our previous research in this area by lifting a number of simplifying assumptions to make the approach applicable in real-life, and by extending our study to frequently used SLAs in practice. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICES-0021/SERVICES-0021.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2411</link>
<description><![CDATA[Communication cloud is a new type of cloud computing paradigm to address real-time and near real-time communication needs that encompass various aspects of unified communication and web centric intelligent communication endpoints. One important development of communication cloud is Google&amp;rsquo;s Wave initiative. It offers many critical features in unified communication, e.g. social networking, federation, tagging, collaboration, etc., from a cloud computing and HTML5 based browser environment. <div><br><div align="left"></div><br><a href="http://www.servicescomputing.tv/rss/view/uploadfiles/2009\PPT\Congress2009-1005.ppt.\"  target=_black></a><br></div><div></div>]]></description>

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2414</link>
<description><![CDATA[In this paper, we present a novel combinatorial auction (CA) based Cloud market model that facilitates dynamic collaboration (DC) among Cloud providers (CPs) for providing composite/collaborative Cloud services to consumers and hence can address the interoperability and scalability issues for Cloud computing. Also to minimize the conflicts that may happen when negotiating among providers in a DC platform, we propose a new auction policy in CA that allows a CP to dynamically collaborate with suitable partner CPs to form a group before joining the auction and to publish their group bids as a single bid to fulfill the service requirements completely. But to find a good combination of CP partners is a NP-hard problem. So we propose a promising multi-objective (MO) optimization model for CP partner selection that not only uses their individual information (INI) but also their past collaborative relationship information (PRI) which is seldom considered in existing approaches. A multiobjective genetic algorithm (MOGA) called MOGA-IC is also developed to solve the model. We implemented our proposed CACM model and the MOGA-IC in a simulated environment and study their economic efficiency and performance with existing model and algorithm. The experimental results show that the proposed MOGA-IC can support satisfactory and high quality partner selection in CACM model. <div align="center"><a href="uploadfiles/2009/VIDEO/SERVICES-0002/SERVICES-0002.html" target="_blank"><strong>&amp;gt;&amp;gt;&amp;gt; View Video(Flash Player 9 please.

<link>http://www.servicescomputing.tv/rss/view/readarticle_view.php?info_id=2416</link>
<description><![CDATA[Many of the most complex service systems being built and imagined today combine person-to-person encounters, technology-enhanced encounters, self-service, computational services, multi-channel, multi-device, and location-based or context-aware services. I examine the characteristic concerns and methods for these seven different design contexts to propose some unifying themes that span them, especially when the service-system is &amp;ldquo;information-intensive.&amp;rdquo;<div><br><div align="left"></div><br><a href="http://www.servicescomputing.tv/rss/view/uploadfiles/2009\PPT\Congress2009-1002.ppt.\"  target=_black></a><br></div><div></div>]]></description>
