Mobile office is becoming common as advances in mobile devices such as PDAs, Smart-phones, or wireless Internet. In this paper, we construct a mobile office environment on a geotechnical information system(GIS). Especially, web services and XML technology combined with SOA (service oriented services) are adopted for various types of mobile devices and services in a minimum cost. Web service and XML can provide an excellent SW reusability, extensibility, and interoperability even for heterogeneous distributed systems. Applications can exploit web services by just knowing server's address. Prototype system integrates a client in Visual Basic.Net and server in Java via the web services and XML data exchange. We verify effectiveness of the approach through the implementation of prototype system.

Recently, in spite of fast development of smartphone, recording technology has saved, listened and searched in server based on PSTN and wired network. We introduce a mobile transcript recording system for mobile office environment. All calls using smartphone are automatically saved on memory in mobile device with this system. Thereafter, recording files are encrypted and uploaded to recording server by user authority. Beside recording data in database on web server is saved and managed efficiently and economically through web application. This system is able to be used in legal corroborative facts and the prevention of crime such as voice phishing.

Given the growing deployment of mobile offices, we need to understand the fectors which affect their successful use and implementation. We in this paper present a parsimonious model which integrates the IS success model and the TAM. The main feature of the model is that it allows one to explore the role of mobility of mobile office systems in determining the level of system usage and dependence. Although the mobility is the key property of any mobile system, there is little research effort exerted to understand how mobility affects the traditional IS factors such as perceived ease of use and usefulness. In addition to the system usage, this model also uses dependence as the dependent variable. This is expected to provide richer understanding of the study context. We collected survey data from 1,614 field service workers of a major domestic electronic company. They use PDAs to retrieve information regarding the specifics of the customer service requests and to report what has been done for each service job. The results from SEM analysis show that mobility improves the perceived ease of use which then leads the field service workers to depend more on the PDA systems. Interestingly enough, however, the workers' satisfaction does not cause more frequent use of the system.

Smart work has been gaining more popularity recently. Smart work means that employees perform their works anytime and anywhere as utilizing the information and communication technology. It can be divided into four categories; the mobile office, the home office, the work-at-center and the tele-cooperation. Among them, the mobile office based on tablet personal computers(PCs) or smart phones, employees can exchange information with tablet PCs or smart phones via mobile radio communication networks and portable terminals. Smart devices such as tablet PCs and smart phones help to access intranet system for requests, approvals, information search whenever employees need. This mobile office system for real-time HSE managing can contribute to improve the productivity and work efficiency in a shipyard. In this study, the main goal is to design the specialized mobile application for the HSE management system on the shipbuilding industry. The mobile application including 10 functions is designed based on ooCBD(object-oriented Component Based Development) methodology.

지능형 교통시스템(ITS)은 기존의 교통 정보시스템에 첨단 통신기술을 접목하여 교통 시설 운용의 효율성을 극대화시키고, 향후 mobile office 구현을 목표로 활발한 연구 중에 있다. 또한 mobile office의 대표적인 서비스로는 Internet 서비스가 있으며, 현재 ISO／TC204 WGl6(CALM)에서 활발한 연구 중에 있다. 본 논문에서는 mobile office의 대표적인서비스 예로 인터넷 서비스 제공 시 무선환경에서 야기되어지는 핸드오프 방안에 대한 알고리즘으로 HiN-handoff 알고리즘을 제시하였다. HiN-handoff(handover) 알고리즘은 기존의핸드 오프 알고리즘의 보완방법으로 차량에서 고속 주행 시 단절구간을 미리 예측하여 handoff(handover)를 극복해 보고자 하는 알고리즘이다.

SMRT(Seoul Metropolitan Rapid Transit Corporation) changed PC-oriented office system to Smart-Phone oriented mobile office system(STnF: SMRT Talk & Flash), and provided smart phone to all staffs. STnF make it possible not only voice communication between staff, but also to input and inquiry all kind of information related to work(ex: Facility maintenance, Rolling Stock management, office management, Finance, human resource etc.) based on smart phone. STnF conquers the limitation of time and space. All staffs can commute to the site directly to reduce moving time and to share information between staffs, so SMRT improve speed and reliability of work by making a quick decision and action on the spot. After introduction of STnF, within 1 year, the equipment failure ratio fell to 47%. Mobile office system reduced and level-off the step of approval. so enhanced civil customer service. Quantification and scientific movement of work make it fast evolution and development. These business improvement make it possible to put more outstanding manpower on new business and R&D project, and this contributes to company's management effectiveness.

Smart work can classify three types. First, mobile office equipped with a portable computer and connect to the company servers and Intranet via mobile phones. Second, home working using video conference system. Third, smart work center. Smart work has enabled us to work efficiently, to work anytime and to work anywhere, beyond conventional office working. This paper presents development processes of a smart work for After Service Business, especially, for the elevator industry. we called implemented mobile office system "A/S work". A/S work using mobile devices has some advantages as compared with previous system. 1) Before/After photo management function 2) Assessment process of customer satisfaction 3) The work history management app. 4) The inquiry and confirmation function to current status of all workers 5) The group SMS function sending selected workers. 'M' elevator company has used A/S work as efficient smart work system.
