The control of electrical appliances residing in the home network can be accomplished via Internet with the UPnP expansion without modifying an existing UPnP. In this paper, we propose the Internet Gateway that consists of an UPnP IGD(Internet Gateway Device) DCP(Device Control Protocol) and an UPnP Bridge as a system to control electrical appliances of home network. UPnP IGD DCP is to enable the configurable initiation and sharing of Internet connections as well as assuring advanced connection-management features and management of host configuration service. It also supports transparent Internet access by non-UPnP-certified devices. UPnP Bridge searches for local home network devices by sending control messages, while control point of UPnP Bridge looks up devices of interest on the Internet, subsequently furnishing the inter-networking controlling among devices which belong to different home network systems. With our approach, devices on one home network can control home electrical appliances on the other hone network via Internet through IGD DCP with control commands of UPnP.

Recently The social interest regarding is coming to be high about Home Network accordong to intelligence anger of diffusions and the family home appliance machineries and tools of the superhigh speed Internet In the ubiquitous computing socioty, only neither the threat of the private life which is caused by in cyber attack will be able to increase according to the computer environment dependence degree of the individual increases in the ubiquitous computing socioty, only neither the threat of the private life which is caused by in cyber attack will be able to increase according to the computer environment dependence degree of the individual increases Beacaues of Home network is starting point to go ubiquitous computing enviorment, The Increase of Cyber attack through Internet will raise its head with the obstacle to disrupt the activation of the groove network. So there is a possibility of saying that the counter-measure preparation is urgent, In the various environment like this, It means the threat which present time than is complicated will exist. So it will analyze the Home network system environment of present time and observe the Security threat and attack type in the ubiquitous computing enviorment. So it will analyze the Home network system environment of present time and observe the Security threat and attack type in the ubiquitous computing enviorment.

The Purpose of this study was firstly to identify the living characteristics of apartment residents in relation to the behavioral patterns in the kitchen and utility space and secondly to present the basic material necessary for planning the kitchen and utility space of future desirable apartments with consideration for resident usage. The findings are summarized as follows : 1) Behavioral patterns in the kitchen and utility space were classified as personal life, family with harmony, talking with visitors, caring for children, cleaning, cooking, and keeping and connecting. 2) Behavioral patterns in He kitchen and utility space showed patterns on personal life, family with harmony, and talking with visitors and were used in the kitchen including the dining room. 3) As the required kitchen size and sink arrangement varied according to the kinds of furniture appliance, plan for the kitchen wok is very necessary.

In this paper, we propose a new personal agent for generating the combinational services from using history of appliances in the home network environment. In such environment, it is required that flexible services can be provided by combining services of appliances and unskillful users can use these services without knowledge. So, it is needed to satisfy following: (1) combinational services can be suggested automatically and (2) the increase of services can be followed. Then, we propose a new personal agent that suggests combinational services by learning the lifestyle. Its learning mechanism is based on Self-Organizing Map (SOM), and can follow the increase of services. We implemented the the agent, and use history of a user for two weeks was made to learn. As the result, we confirmed that the agent can extract services related with time or location and can suggest combinational services.

As the robot industry changes from industrial robot into personal robot used in home, the concept also changes from the existing fixed manipulator into Mobile Manipulator of free move in the aspect of appliance. For personal robot with such features, the role of mobile system is very important technology that rules the roost of robot functions. Especially, it is necessary to develop moving mechanism for free move in a narrow environment with obstacles such as home. This study introduces 3-axis structure in order to develop synchronous method that has turret capable of endless revolution for practical use as well as semi-omnidirectional function, and suggests applicable method to solve the problem of mechanical coupling.

Recently, low energy houses have become an essential issue globally and various subsidy programs are ongoing to penetrate. All-electric houses which are another type of low energy houses or zero carbon houses are being developed. These houses consider new & renewable energy and demand side management programs in the construction and the diffusion process because these programs are essential policies to use energy resources reasonably. This paper shows a simulation methodology to control home appliances in all-electric houses considering the electricity consumption pattern of residents. The simulation is a first step to estimate energy saving of the house in a practical manner.
