In existing internet, e-mail protocols including POP3 and IMAP4, provide e-mail services fir exchanging messages with texts, hypertext and images as well. For the e-mail services in wireless mobile network, mobile e-mail service providers have to install a mobile exclusive e-mail server or have to convert e-mail to mobile exclusive e-mail with wireless application format in case of POP3 protocol. In the e-mail service of IMAP4 case known as web-mail, it is difficult to view e-mail directly from server without IMAP4 mobile client because e-mail is stored in mail server side with remote file server. In either case, it also has the problems of viewing the e-mail of hypertext and image information at mobile. This paper provides e-mail extraction engine with image and hypertext conversion facilities that can be applied in wireless mobile internet and it is optimized in mobile communication environments such as a small display, small size of memory with web-mail protocol based on IMAP4 as well as POP3 mail protocol.

To determine factors affecting social network service e-service quality, this research is to investigate factors of social network service e-service quality, and analyze how these factors influencing on social network service e-service satisfactions. As a results, three dimensions were identified namely, fulfillment, ease of use and playfulness. But two dimensions were rejected namely connectivity, security. It indicates that the qualitative aspect is becoming more important than quantitative in social network service management.

해사안전정보(MSI)는 항행경보, 기상특보, 안전관련 긴급 정보로 구성되어 NAVTEX와 SafetyNet 체계를 통해 서비스되고 있으며, 서비스 개선을 위한 요구사항으로 해사안전정보의 필터링과 전자해도 시스템과의 연계 방안이 제시된 바 있다. 국제해사기구의 e-Navigation 전략이행계획의 해사서비스목록(MSP)으로 해사안전정보 서비스(MSP5)가 포함되었고, 국내외 e-Navigation 프로젝트에서는 국제표준에 기반한 해사안전정보 서비스 개발이 진행 중에 있다. 본 연구에서는 한국형 e-Navigation 사업의 중점 서비스로 개발 중인 S-124 표준기반 해사안전정보 서비스 기술 개발 배경과 주요 내용을 소개 한다. S-124는 항행경보와 T&P 항행경보를 포함하는 표준으로, 본 연구에서는 S-124 데이터 모델에 기반 하여 한국형 e-Navigation의 서비스 플랫폼인 MCP(Maritime Cloud Platform)를 통한 서비스 프로토타입 개발 결과를 기술 하였다.

The IMO approved e-navigation strategy implementation plan made e-navigation adoption visible. In addition, the schedule for the modernization of GMDSS by the ITU was confirmed at the 4th NCSR meeting. Accordingly, we will complement the existing communication system and provide the requirements for the new communication system to be introduced in the future, reflecting all the requirements for the communication system capable of supporting the e-navigation service. Although the communication method for supporting e-navigation service should be capable of providing IP-based data communication basically, it is impossible to provide internet service because of the narrow-band characteristic in the MF/HF frequency bands. In addition, as the existing GMDSS satellite communication service organization expands and new services are introduced, IP based data communication service will be possible, but service restriction resulting from expensive communication cost can be solved by introducing VSAT service.

In this paper, we propose a quality interworking control system to enhance user's quality satisfaction in NGN environment by controling QoS parameters related with QoE in network layer when service user's QoE using variance multimedia service is poor. The proposed system gathers QoS parameter information in network layer through control packet such as RTCP, and evaluates QoE of multimedia service using these QoS parameter information. Comparing the evaluated QoE with the measured QoE in application layer, QCS judges quality degradation, deduces related QoS parameters and decides relative importance of each parameter when QoE is lower than threshold value. QCS generates QoS control values which is based on routing and switching policy in service quality control system(SCS) and forwards them to SCS. Through this proposed system, service and network providers can provide multimedia services of enhanced quality to service users taking account of service characteristic and network performance.

The Korean government has done annual fact-finding surveys on the use of e-government since 2007, but put little effort to analyse and draw implications. We analyzed the trend of the use of e-government in Korea using the survey results of 2012~2015. While the awareness and the user uptake of e-government in Korea have increased steadily, the relative portion and frequency of the use stagnates and falls back. Korean citizens still utilize in-person channel more than e-government channels, and the speed of the transfer from the former to the latter is not fast enough. While more than 95% of the Korean people intend to use the e-government as the main channel in the future, their actual rate of use was 43.2%. We suggest following measures to overcome the troubling situation and increase the uptake of e-government services in Korea through: the expansion of mobile e-government services, strengthening of seamless services, elevation of the level of customization, increasing frequency of using the current e-government services, and raise of the awareness level and the improvement of Korean E-Government Portal.

There are two streams on e-Learning. The first one is to create new value through aligning products included information systems and service. The second one is to utilize the service system and the service process for service systematization. The service system is made up human, technology, value proposition, service network, and shared information. The service process consists of design, development, operation and evaluation phases. In this paper, we design and implement the evaluation management of e-learning service based on the service science. The evaluation management service is sets of evaluation type management, general review management, award management, evaluation sheet management and evaluation result management. Feature of this paper is that we can service with different criteria to learner, guardian and evaluator. The worthy of this paper is that we construct service oriented environment possible to systematize evaluation work easily and provide evaluation results clearly.

E-Mai1 서비스는 현재 가장 많이 쓰이는 WWW 시스템의 가장 기본적인 기능이다. 그러나 현 e-mai1 서비스는 텍스트 기반 구조를 통한 비동기적인 형태의 서비스를 계속 유지하고 있어, 동기적인 표현방법이 요구되는 실정이다 따라서 단순한 정보의 제공을 위한 서비스로서가 아니라, 사용자가 직접 설정하여 서비스를 받는 형태의 e-mai1 을 제안하고자 한다. 사용자가 지정해놓은 사전을 기반으로 HTML 문서가 재생산되어, 색 지정 기능과 하이퍼 텍스트 기능을 제공하는 한편, 사전에 등록된 정보를 바탕으로 개체에 대한 정보가 tooltip으로 표시될 수 있도록 하는 사전기반 하이퍼 문서 생성기능을 지원하도록 한다
