Schedule Management for outside duty personnels and their groups is fairly difficult since they spend most of their time on working outside individually rather than inside office. Everytime when schedule change for personnels or their groups is needed, it is necessary to call every personnel in order to notify the schedule change. It would be much easier to handle the schedule management problem if outside duty personnels are able to download schedule of their groups(and, upload their schedule) using their mobile communication devices such as PDAs. In this paper, using a data synchronization protocol in mobile communication environments, a schedule management system for outside duty personnels is designed and implemented. Data synchronization in mobile communication environments is a process of maintaining consistency between data stored in mobile devices and data stored in a (central) server at office. In other words, using SyncML data synchronization protocol proposed by OMA(Open Mobile Alliance) as an open standard for data synchronization in mobile communication environments, a schedule management system for outside duty personnels which allows them to check schedule of their groups and to notify their schedule to their groups at anytime anyplace is designed and implemented.

In today's competitive business environment it is a necessary condition for a company to produce high-quality product for its survival and growth. That is the case in the auto-part industry as well where the international standards, ISO/TS 16949 certification, are required by customers to adopt mandatory. This study presents a successful implementation of quality management system(QMS) in a major auto-part manufacturer in Korea, utilizing SAP's QM(qualaity management) module and a mobile office system. The QMS brought the company "A" a variety of benefits such as real-time availability of product-inspection data, speedy decision-making, reduction in time required for defect-handling, ease of vertical integration of business partners in supply chain, and ease of business process standardization between headquarters and overseas subsidiaries. It is expected that the findings of this study can be used as a useful guideline for companies to consider implementing ERP-based quality management systems successfully.

According to spread of Smart Work introduction to public organizations & commercial enterprises, its being more focused on how to implement Smart Work effectively. So far current Smart Work, mainly Mobile Office has emphasized the speed & efficiency of management. But future Smart Work, Smart Work 2.0 must focus on the creativity & innovation of companies & people. In order to do that, the new technology like Social networking & Cloud computing should be applied. This study suggests Smart Work 2.0 implementation methodology including critical successful factors & solutions of Smart Work implementation through referencing existing implementation methodology and case study.

Taipei Water Management Office (TWMO) is one of the eleven district offices in Water Resource Agency. Water management is the top priority to be pursued both on daily management and long-term management at TWMO. There are five departments to perform a wide range of tasks in addition to water management. All management prescriptions are simply to provide sustainable clean water for about four millions population in Taipei. TWMO has gone through 16 years experience of development and implementation of GIS in water management. The objectives of this paper are to provide the major ingredients of successful and operational GIS for water management. The five departments at TWMO have performed tasks such as city planning, construction management, forest management, land use enforcement, soil and water conservation, water quality monitoring and protection, garbage collection, and sewage disposal management. Data base creation was one of the major jobs to be done. Update of data base has to be done on a daily basis. Computers, its peripheral, and software are essential for GIS developed at TWMO. Know-how and technical skill on computers and GIS for every technician are contributing significantly such that GIS can be implemented on most of jobs performed at TWMO. Implementations of GIS have been pursued by application modules on a task-oriented basis. Application modules are simple, easy to use, and menu driven with only Chinese. Web-based and mobile GIS are the new components that make water management at TWMO stay on the right course. To solve problems encountered in water management by GIS at TWMO can be easily and user-friendly may be the most important experience.

An open office or a shared office is emerging as the emphasis on the collaborative and communicative work environments is increasing. In the past, the user maintained the space, but the maintenance of indoor space became difficult because there is no fixed user. Indoor space information can be collected using the ICBM framework system. The facility management can achieve this with data. Therefore, this study proposed a framework based on ICBM (Internet of Things, Cloud, Big Data, and Mobile) for verifying the possibility of a smart facility management system for indoor space. IoT (Internet of Things) technology was used to measure the indoor temperature, humidity, occupancy, and brightness continuously, and provided the data to Web API via WiFi. Data acquired automatically via IoT, existing maintenance data, and spatial information were integrated through the Cloud. Big data collected by sensors were processed as meaningful spatial information for maintenance. Indoor space information and maintenance information can be delivered to the manager through the mobile. Based on the collected data, room occupancy recognition is limited due to a range of ultrasonic wave sensors. On the other hand, brightness represents the space conditions. The difference between lighting on/off, weekday and weekend can be shown. The temperature data and the relative humidity data were collected steadily to evaluate the comfort.

Recently, the progress of industrialization has been taken concern of material handling automation. So for, the conveyor belt has been popular for material handling. However, this system has many disadvantages such as the space, cost, etc. In this paper, a new navigation algorithm using fuzzy is introduced. The mobile robot follows a line installed on the roads. These informations are inputted with three approximate sensors. These obtained informations are analyzed with fuzzy control technique fur autonomous steering. Therefore, unlike existing systems, high reliability is guaranteed under bad environment conditions. The installation and maintenance of a line is easily made at lower cost. This developed mobile robot can be applied to material handling automation in manufacturing system, hospital, inter-office document del ivory.

In this paper, operations system was designed for the centralization of data processing of various state information from the facilities of mobile communication network. And the system performance experimental system module was measured and analyzed from the designed experimental system module. The configuration of system design was presented with the centralized type to monite and control the facilities of mobile communication network in the central office. The communication process design of the internal system was implemented with the resource of message queue having a excellent transmission ability for processing of a great quantity of information in the inter-process communication among communication resources of UNIX system. The process with a server function from the internal communication processes was constructed with a single server or a double server according to the quantity of operations and implemented with the policy of the presented server. And then, we have measured performance elements in accordance with the change of input parameters from the designed experimental module : response time, waiting time, buffer length, the maximum quantity existing in message queue. And from these results, we have compared and analyzed the system state each server algorithm according to performance variations.

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.
