Recently, organizational workers are complaining of stress due to excessive connection on SNS and are claiming the right to disconnect. If these claims are not properly managed, organizational performance may deteriorate. Therefore, organizations need to approach the issue of the right to disconnect carefully. This study examined the effects of work connection at office, IT hyper-connected environments, and work connection at home on the right to disconnect, and analyzed the effect of this perception on job satisfaction, and then analyzed gender differences in these effects. The research results are as follows. First, it was found that the work connection at office lowered the right to disconnect. Second, the deeper IT hyper-connected environment, the higher the right to disconnect. Third, it was found that the work connection at home raises the right to disconnect. Fourth, it was found that the right to disconnect increases job satisfaction to a certain extent, but lowers job satisfaction when it exceeds the appropriate line. Fifth, in the case of men, the effect of the right to disconnect on job satisfaction has sharply increased and sharply reduced. On the other hand, in women, it gradually increased and then decreased slowly. Considering the results of these studies, organizations need to check the current status and appropriate level of the work connection at home for organizational performance management. Organizations need to formulate organizational management measures that take into account the positive and negative functions of the right to disconnect. And organizations need to come up with management measures that take gender into account.

The Purpose of this study is to investigate both the value consciousness of home management and home management activities which urban low-paid housewives have and to find out the value consciousness of home management has an influence upon the home management activities. The results obtained area as follows; 1) Most of urban low-paid housewives are place in a traditional position of home management as a housekeeper or as a family leader. 2)But partially they gave more or less modern standpoints in consuming, planning and family relationship. 3) The value consciousness of home management of urban low-paid housewives is variable according to housewives' age (P<.05), education (P<.001), numbers of children(P<0.5) and wording experiences before marriage (P<0.1). The younger respondonts showed rather modernistic value consciousness of home management. The respondonts who have high educational level showed the same result. It is also strong points form them to habe few children and to have working experiences before marriage. 4) while the home management activities of urban low-paid housewives are positive as for connecting with human relationship, consuming and evaluating they are negative as for connecting with planning, creativity and housekeeping. 5)On the whole, the home management activities are variable by housewives' age (P<.05). The younger showed more effective home management abilities. 6) the home management activities of urban low-paid housewives are influenced by the value consciousness of home management. The more modernistic value consciousness of home management is connected directed directly with excellent home management activities.

Powerline communication is the data signal which is modulated by carrier frequency through the installed powerline at in-home or office is transmitted and received signals are separated into data signal with using band-pass filter which cent-frequency is carrier frequency. The home gateway, an equipment which works as an gateway for ubiquitous home network, relays all functions of a home network. The home gateway must always be connected in order to provide seamless services. However it gives unfavorable power consumption. Therefore the needs for working in maximum power saving mode while there is no data traffic and for invoking to the normal function when it is necessary. So, in this paper we survey the development of low power PLC modem monitoring of power consumption and breaking abnormal power in the home Network.

There are increasing interests on smart home systems. However, most of the existing works focus on the functionality itself. In this paper, we propose an extensible smart home system based on low power networking such as CoAP, 6LoWPAN, and Zigbee. The proposed home IoT system consists of Home APP, Home Server, Home Broker, and Power Devices. Each component of the system is connected by the low-power network technologies aforementioned. As the end device, Power Device senses the current consumption of the attached appliance and controls the power to it. Power Device reports the sensing data to Home Server via Home Broker. The Home Broker enhances the scalability of the system. Home Broker extends the service area and the user's services, and it manages the connection of the underlying devices and processes, and transmits data to Home Server from Power Devices. Through the experimental evaluation, we show that the proposed system achieves the design goals such as extensibility and low power networking.

Home computers that are connected to the Internet are under attack and need to be secured. That process is relatively well understood, even though we do not have perfect solutions today and probably never will. Meanwhile, however, the home computing environment is evolving into a home network of multiple devices, which will also need to be secured. We have little experience with these new home networks and much research needs to be done in this area. This paper gives a view of the requirements and some of the techniques available for securing home network.
