The OSGi framework is a java-based service platform that can be remotely managed, providing an application life cycle management model, a service registry and an execution environment. Based on the framework, various OSGi layers, APIs, and services have been defined. A bundle is an application that can be executed in the OSGi framework, deployed through a bundle repository. Usually, bundles in the repository are accessible via a designated web page. Unfortunately, the current bundle repositories do not provide any kind of group access services and dynamic bundle installation and deployment. In this paper, we describe a WebDAV-Based OSGi bundle repository named WOBR, which supports effective group-based accesses. WOBR is composed of a WOBR bundle repository, a management bundle and an access bundle that interact with the bundle repository. The management bundle is for configuration of the WOBR bundle repository, managing group access facility to the repository. The access bundle provides access to the repository and search mechanism for the bundles. Additionally, it provides the life cycle management of the installed bundles on the local environment.

As the number of services available on the Web increases, it is vital to be able to identify which services can be trusted. Since there can be an extremely large number of potential services that offer similar functionality, it is challenging to select the right ones. Service requestors have to decide which services closelysatisfy their needs, and theymust worry about the reliability of the service provider. Although an individual service can be trusted, a composed service is not guaranteed to be trustworthy. In this paper, we present a trust model that supports service discovery and composition based on trustworthiness. We define a method to evaluate trust in order to discover trustworthy services. We also provide a method to perform trust estimation for dynamic service composition, and we present results of two experiments. The proposed model allows for service requestors to obtain the most trustworthy services possible. Our mechanism uses direct and indirect user experience to discover the trustworthiness of the services and service providers. Moreover, composing services based on quantitative trust measurements will allow for consumers to acquire a highly reliable service that meet their quality and functional requirements.

This study investigated the status of information services in records and archives centers using the Web to survey and by interviewing archivists and professionals. Services offered are not various, but some actives services including offering records via SNS and provising exibitions using records are offered. Many of the requested records are for evidence and reference for works, and the finding aids are limited in their functions. Also, the barriers in offering services were mostly due to the fact that the duties of managing records are mostly performed by one profession, and they have not enough time to provide services with the lack of manpower. Also the arrangement and description level is not enough and the records systems have limitations including lack of search functions. For better services, improvement of the systems and the supplement of manpower is considered to be most urgent.

The enterprise find a solution to the problems such as a reduction of manufacturing period, accurate analysis for customer demand, improvement for customer service and rise of manufacture accomplishment. Internet is a good solution to such problems. Internet offers WWW(World Wide Web), remote control, file transfer and e-mail service. Among the services, WWW takes large portion because of convenient GUI, easy information search and unlimited information registration. Remote Monitoring Server(RMS) system that uses network service is constructed for chip mounter. Hardware base consists of RMS, chip mounter and C/S(Customer Service) server. Software includes DBMS and various modules in server home page. This provide product number, bad product number, trouble code, content and countermeasure in real-time information module, user information in setup module, detailed error information in fault diagnosis module, fault history in fault history module and customer information in customer service management module.

소매유통업에 있어 충성고객을 발견하고 효과적으로 관리하는 일은 마케팅 부서의 주요 관심사라고 할 수 있다. 최근 성숙된 유통 채널로 자리잡고 있는 인터넷 소매유통업도 다양한 마케팅 노력을 기울이고 있으며 그 성과가 기존 소매유통업 보다 클 것으로 기대하고 있는데 이는 인터넷 소매유통업이 기본적으로 디지털 기반 구조 하에 사업이 수행되기 때문이다. 그러나, 매출 규모가 확장됨에 따라 고객 관계가 보다 복잡해지고 거래 건수도 크게 확장되고 있는 인터넷 소매유통업은 전자적으로 이용 가능한 고객 관리 서비스를 필요로 하고 있다 본 논문은 인터넷 소매유통업의 충성고객관리를 위한 웹서비스의 프레임웍 및 적용 사례를 제시하고 있다. 고객관리 웹서비스의 기본 모델은 전통적인 RFM분석에 기반을 두고 있는데 복잡한 충성고객관리 업무를 처리하는 에이전트를 제공한다. 인터넷 쇼핑몰이나 상점의 운영 시스템과 용이하게 통합될 수 있는 웹서비스는 적은 비용으로 효과적인 고객관리를 실현하는데 기여할 것으로 기대된다.

Mobile service, which is related to all stages of supply chain, can enhance the efficiency of perception and response of the participants. The advantage of mobile service is ubiquity, speed, traceability, positioning, personalization and safety. The purpose of this paper is to propose an overall framework utilizing mobile service in SCM. In the areas of inventory management, remote diagnostics, communications with field workers, and order fulfillment, customer-centric mobile supply web is proposed and implemented for the wireless warehousing and replenishment system.

The proliferation of mobile and tablet PC has been collapsing down geographic boundaries. Accordingly, the global cultural and artistic activities and public cultural content exchange have been enlarged. With the spread of Web 2.0, users can easily access a variety of cultural contents. However, each local government develops applicable technical and cultural content service on their own without consulting any best practices or standards. In addition, unlike traditional contents services mobile content services should take into account the characteristics of the environment. It is also necessary to provide personalized contents in a timely manner. In order to accelerate the future mobile environment, this study presents a mobile web service practice that was developed based on the current state for mobile services and a cultural contents derived from standards and effective deployment of the service plan focusing on the case of "The Encyclopedia of Korean Local Culture".

The most representative research network in Korea, KREONET, has developed DynamicKL, an advance reservation based Network Service Agent (NSA) for user driven virtual circuit services. DynamicKL provides reservation, provisioning, release, termination, and inquiry web services for network resources by using an open standard network service interface (NSI), as well as web services for network resources by using a GUI interface. In addition, it has the RICE interface to support a protection management function per VC for virtual circuits and reservations. In this article, a protection management per VC for provisioned VCs and reservations is addressed in the DynamicKL framework, as a contribution to the VC protection management issue, which results in more manageable and reliable VC services compared to other advance reservation frameworks. An administrator can detect successful or unsuccessful VC protections in the event of a primary link failure and successful or unsuccessful VC retrievals after a primary link repair, by using RICE.

Open Science is evolving not only to share research results, but also to open the research process. We are developing the EDISON platform for the spread of open science in computational science and engineering. The EDISON platform provides online simulation services developed by computational science and engineering researchers. It also provides an environment for sharing source code, data, and related research publications. An effective simulation software registration management system is required for successful service on the EDISON platform. In this paper, we proposes a simulation software management system to provide online simulation service through EDISON platform. The proposed system allows the developer to register the simulation software on the EDISON platform without administrator intervention and effectively build a web-based simulation environment.
