스마트폰 시장의 규모가 급속하게 확장됨에 따라 모바일에서 다양한 서비스가 제공되면서 기업의 측면에서는 스마트워크 환경에서의 모바일 오피스 시스템 도입 요구가 커지고 있다. 그러나 스마트폰의 이동적 개방성의 특성은 기업 정보의 접근 및 유출의 위험성을 갖고 있어 이에 대한 시스템 구성에서의 보안 및 안전성 확보가 필요하다. 본 논문에서는 USIM을 이용하여 모바일 오피스 사용의 정당한 권한이 있는 사용자임을 등록 및 인증 후 안전한 서비스 사용이 가능하도록 모바일 오피스 시스템을 설계하고 분석한다. 제안 시스템은 모바일 오피스의 시스템 구성 요소 간의 안전한 통신 상태를 보장함으로써 기업 정보의 사용에 있어 보안성을 효과적으로 제공한다.

This paper focuses on developing a smartphone-based mobile office system for a logistics company in Korea using HTML5. Mobile office is smart working environment of working out of a company office using mobile devices such as smartphones and portable computers which are connected to the company servers via WiFi or 3G/4G. Recently many companies are introducing mobile office information systems with the smartphone wave, but they are having difficulties in maintaining and updating their systems due to the transformative mobile application platform. Therefore, we need a platform-independent implementation tools for the mobile office application and HTML5 is one of the solution tools. In this paper, we develop mobile and web applications applicable to all kinds of mobile devices such as iOS, android and windows mobile etc using HTML5. The proposed mobile office system consists of groupware, marketing management, reporting module and transportation management system.

최근 저출산 고령화 등의 사회문제와 글로벌 환경문제가 심각하게 대두됨에 따라 스마트워크와 모바일 오피스 등 새로운 개념의 근무형태에 대한 중요성과 관심이 커지고 있다. 하지만 이러한 중요성에도 불구하고 대부분의 기존 연구는 스마트워크 또는 모바일 오피스의 도입 효과에 대해서만 논하고 있으며 실질적인 활용과 업무 만족도 향상 등 활성화를 위한 구체적인 방안에 관한 연구는 미비하다. 따라서 본 연구는 모바일 오피스 활성화를 위해 필요한 조직적 측면의 지원에 대해 분석하고자 한다. 이를 위해 모바일 오피스 사용자 172명을 대상으로 설문을 실시하여 조직에서 제공하는 물리적, 금전적, 업무적 차원의 지원이 모바일 오피스에 대한 사용자들의 인식과 활용, 그리고 만족감에 미치는 영향을 실증적으로 분석하였다. 분석 결과 조직지원은 시스템품질이나 정보품질과 같이 사용자들이 모바일 오피스에 대해 인식하는 품질을 통해 모바일 오피스 활용 및 만족도에 유의한 영향을 미치는 것으로 나타났다. 이러한 연구 결과는 모바일 오피스 활성화를 위한 구체적인 민관의 지원방안과 시사점을 제공했다는 점에서 의의가 있으며, 모바일 오피스 관련 정책 및 전략 수립의 가이드라인으로 작용할 것이다.

It is required for enterprises to construct the proper information management system in order to cope with the volatile business situations. The mobile office system is introduced from the needs to provide organization members smart information and mobility. By setting the model, hence, we intend to scrutinize the impact of the task-technology fit model and organizational characteristics of the mobile office system on the job performance. As a result, system quality, information quality and mobility are revealed to affect positively the task-technology fitness and the fitness also affects the job performance positively. Organization characteristics affects the job performance positively through the task-technology fitness, too. Therefore the organization which plans to introduce the mobile office system should consider the task-technology fitness and exert organizational-level efforts to adopt and use the mobile office system in the workplace.

In this paper, a mobile office support. system which consists of mobile devices and servers is proposed. An efficient mobile office support system is required to study since the existing mobile office support systems may face the serious problems such as an absence of interoperability, difficulties of data synchronization and device management in the near future, especially when a company has a large number of outdoor service employees. In this paper, a mobile office support system requirements for a company with a large number of outdoor service employees is proposed. And then, the methods to satisfy the requirements using a remote data synchronization and a remote device management technologies are proposed. The mobile office support system proposed in this paper synchronizes remotely a large number of various mobile devices of employees with centralized servers located in the company. In addition, it manages the mobile devices remotely for the employees. This paper proposes a mobile office support system based on OMA(Open Mobile Alliance) DS(Data Synchronization) and DM(Device Management) protocols. As OMA DS and DM protocols are de facto international standards, the interoperability between the mobile office support systems can be guaranteed.

현대 사회는 모바일 장치와 통신기술의 발달로 장소와 상관없이 자유롭게 네트워크에 접속할 수 있게 되었다. 모바일 디바이스 사용자의 폭발적인 증가는 이동성이 보장된 모바일 오피스 환경 구현을 가속화시키고 있으며 개인의 모바일 기기를 업무에 사용하는 경향도 두드러지고 있다. 개인소유 디바이스를 통해 기업 네트워크에 접속하는 횟수가 늘어나면서 기기를 통해 중요한 데이터의 분실이나 유출과 같은 보안 문제를 해결하려는 연구들이 발표되었다. 이와 같은 보안 문제 해결 방안으로 통합적으로 이동 단말을 관리하는 MDM(Mobile Device Management) 시스템 도입이 전망되고 있다. 하지만 아직 MDM 시스템에 대한 위협, 보안에 대한 연구가 미흡하다. 이에 본 논문에서는 보안강화와 효율적인 MDM 시스템 사용을 위해 MDM 시스템을 기반으로 위치정보를 활용하여 모바일 오피스 보안 시스템을 설계하였다.

Recent increases in uncertainty and speed of market change are driving the adoption of new intelligent mobile office systems. Organizational information systems paradigm suggests that a right match between organizational characteristics and the use of technology is critical in producing desired results. Following such perspective this study developed the mobile office system case of Seoul Metropolitan Railway Transit(SMRT) in Korea. SMRT developed the mobile task-supporting environment that help the management of subway lines real-time without the restriction of time and space. They named the system as ST&F(SMRT Talk and Flash). They decided to develop the application systems in-houses they did not want to be overly dependent on external services in future changes and developments of the system. The new practice reduced the time for moving back and forth to 10% of their working time from previous 20%. The time used for paper works and administration chore also reduce to 10% of their working time from previous 30% on the average. The employees could use 80% of their time to concentrate on the completion of assigned task. The effects of this improvement resulted in the heightened efficiency of the use of human resources and the heightened level of railway safety. The case of SMRT shows that the mobile office system can be applied and extended to various business areas such as facility management and maintenance beyond such typical uses as sales and marketing support. Also, The result of case study will be a useful guideline on the construction and using of mobile office system.

Since the supply of smart phones, a change in mobile environment brought a turning point called a mobile generation. Smart mobile office is a combined form of smart phones' new mobile environment and its social media. A construction of mobile office environment using smart phones brought revitalization of the smart phone market. CRM construction also became new requirements for a customer management. However, based on the current information system audit standard, check fields or check lists are insufficient to apply to audit for CRM construction in a smart mobile office environment. Therefore, this paper proposes a model for auditing CRM system construction in smart mobile office environment. It proposes audit domain and check lists of CRM construction. It also verified whether the proposed model is suitable or not by doing a survey if deduced audit domain and check lists correspond with the purpose of the CRM construction audit during smart mobile office environment. As the result, this study appear to have more than average satisfaction the suitability results were.
