Human being does work to live out and they have their private life because human has sociality. Both work and life are important to live out but they are on the trade-off relationship. Because keeping the balance between work and life is too hard, it has been interested by academic and practical areas. Definition of Work-life balance here is that balance or imbalance arising between work and life has no negative impact on their daily life. Above all, Work-life balance is important because it is strongly related to identity. Recently, the introduction of the mobile office system has emerged as a way to solve the problem of work-life balance. It is based on the teleworking which was formerly generated. Teleworking is to perform the work in the employee's home or office space set aside without going into the workplace. Concept of the mobile office system here is not only using portable devices during work for convenience but also the system which is designed for the performance. Thanks to the diffusion of smart devices(smart phone, tablet pc), mobile office system has been spread. Although the importance of mobile office systems is emerging, there are few researches about it. Even they mostly focus on the standpoint of performance of mobile office system. However, Quality of life is as important as the performance. As a part of Quality of Life field, Work-life balance is the closest to employee's quality of life. So this study aims to examine the effect of the use of mobile office systems on work-life balance. To do so, we try to find factors effecting Work-life balance from existing studies and then set a research model. We set the use of mobile office systems as independent variables which are divided by use of function, use by location and use by situation. There are four dependent variables - sense of self command, sense of balance, solving work problem, solving life problem. We collected data from employees who are using mobile office systems on their job. 215 people were participated in the survey and we used multiple regression analysis to verify our research model. Results show that every independent variable has no impact on solving work problem while they have slight impact on the other dependent variables. Especially use on the business trip has significant effect on dependent variables. It means that there is a possibility use of mobile office system could control the employee's quality of life and system should be evolved until it covers even critical tasks. Also, support for mobile office system -education, encouragement-should be provided. By mobile office system is maturing, future research would be done.

As the IT industry has developed, the frequency of mobile communication usage has increased sharply. Mobile communication has many advantages such as improving work performance, communication beyond time and local constraints, and rapid and vast amounts of information exchange. However, mobile communication also allows supervisors to give their subordinates work at any time. Thus, mobile communication may also have a negative impact on workers' stress levels during non-work time. This study examined required time, urgent business, personal engagement, and trivial matters as sub-dimensions of mobile communication messages that workers could receive during non-work time. Further, the nature of the relationship between team leaders and members explains how these messages may increase the stress levels of workers. Supervisors should prohibit the use of such mobile communication, and efforts should be made at the enterprise level. Through this research, we aim to explain the dual nature of mobile communication, and understand how to optimize the usage of this innovative technology

The use of mobile office systems has been expanded due to the smartphones' rapid diffusion in Korea, and it has brought a new work environment that is different from traditional working patterns. In this study, the unique attributes of mobile office systems, such as ubiquity, usefulness, complexity, and insecurity, are examined along with the impact of these attributes on work overload and job stress. Based on transaction-based model of job stress, organizational support was applied as a stress inhibitor and also the moderator between work overload and job stress. The findings of this study show that ubiquity increases usefulness of mobile office systems; complexity increases both work overload and job stress; and insecurity increases job stress. Surprisingly, usefulness increases job stress, which means employees who perceive the efficiency of mobile office systems higher may feel more job stress. Organizational support for mobile office systems significantly shows the moderating effect, but no direct mitigating effect on job stress. The theoretical and practical implications in order to mitigate the side effects of mobile office systems based on the research findings are thoroughly discussed.

When various work was given from user, the existing mobile agent model migrated from node to node and process the work at the point that much traffics according to passive routing schedule are happened, until it makes service the work result, time cost of round work process for the distributed nodes are increased. Therefore, the existing agent systems need migration method to solve the problems of agent size increment or a lack of interoperability among agent systems. To solve these problems in this thesis, we design and implement an CORBA-based Mobile Agent Model(CMAM) for the efficient work process into the distributed nodes, when the mobile agents are migrated among the nodes, using an optimal path search by sensing of network traffic.

According to the statistics of occupational accidents in 2009, the scaffolds and work platforms were main objects causing fall accidents in construction sites. But many workers install and use the work platforms on the mobile scaffolding without considering about safety standards. We had conducted a nationwide survey about how workers obey safety standards for the work platforms of the mobile scaffolding. As the result of a survey, no one follow a gap standard between materials of work platforms and installation of toe board. And it is a low proportion that comply with the install of safety guard rails and the use of stoppers. This is lack of consciousness for the safety certification and regulations. For safe use a mobile scaffolding, It is needed to educate a manager on the safety standards and to develop a product to install and dismantle easily.
