The smart phone has already proliferated, and the smart devices of the living appliances and vehicles embedded with communication device, sensors and connected with the smart phone have been developed. Currently it can provide simple remote controller and user interfaces, it could be envisaged that intelligent technology is converged with the smart phone, and Personal Environment Service in which the smart devices are configured automatically as reflecting personal preference, device attribute, and living environment condition would be activated in the future. In this paper PES services, system architecture, and core technology are described.

In this paper, the required frequency bandwidth for short range communications and mobile communication networks is analyzed for the matured Personal Environment Service, which establishes intelligent personal living environment with connecting the mobile phone and living appliances to WPAN, mobile communication networks, and Internet. In spite of rough estimation of the service needs, this paper shows the calculation method of required frequency bandwidth for the service and the considerations for the Ubiquitous era in advance.

In this study we tried to give a decision on propriety of working conditions, to present ideas on reducing work loads, and to grope for efficiency of agricultural works. For this we examined the actual working conditions of cultivating welsh onion in the summer ground. And we improved harmful factors that affect farmer's health by considering results of previous study and farmer's subjective sensation. And we measured. compared, and analyzed the farmer's work loads before and after improvement. The results of this study are as follows ; 1. According to examine the actual working conditions of cultivating welsh onion in the summer ground, farmers have experienced physical and mental chronic fatigue on the basis of farmer's appel to eye - fatigue and sun - burned skin on hot working environment including excessive ultraviolet rays, the rough ground condition, inconsistent arrangement of working stand and sorter, heavy - weared habits, and unsuitable working posture. 2. When we improved harmful factors that affect farmer's health, conformed the effects on important work efficiency index such as heart rate, electromyovolume, body temperature, and microclimate inside clothing and work loads were decreased by eliminating the hillock and obstacles of ground, decreasing the clothing weight, using proper clothing appliances such as hat and sunglasses, controlling height of working stand and sorter suitably, improving the working postures and methods as using assistant appliances, alloting the working time and sequence effectively and presenting the light gymnastic exercises and rest for fatigue restoration.

Recently in the area of ICT, the M2M and IoT are in the spotlight as a cutting edge technology with the help of advancement of internet. Among those fields, the smart home is the closest area to our daily lives. Smart home has the purpose to lead a user more convenient living in the house with WLAN (Wireless Local Area Network) or other short-range communication environments using automated appliances. With an arrival of the age of IoT, this can be described as one axis of a variety of applications as for the M2H (Machine to Home) field in M2M. In this paper, we propose a novel technique for estimating the location of a terminal that freely move within a specified area using the RSSI (Received Signal Strength Indication) in the WLAN environment. In order to perform the location estimation, the Fingerprint and KNN methods are utilized and the LMS with the gradient descent method and the proposed algorithm are also used through the error correction functions for locating the real-time position of a moving user who is keeping a smart terminal. From the estimated location, the nearest fixed devices which are general electric appliances were supposed to work appropriately for self-operating of virtual smart home. Through the experiments, connection and operation success rate, and the performance results are analyzed, presenting the verification results.

Community gardens with log house in rural areas as a rural growth tool are able to promote rural-urban exchange and adapt to current market mechanisms by means of communication and promotion techniques. It is important to know that what community garden's users seek for their benefits and demand for well-established and settled down. The primary purpose of this study was to examine the needs of dwellers to live their community gardens so as to provide a better understanding of community gardens in Korea. An open-ended questionnaire survey was obtained from ten householders on community gardens in the study area. The results show that there needs to establish facilities such as small storehouse for farming appliances and barbecue area, and to set up the regulation to control a loud talking and sing until late night. We suggest that the government supports to help dwellers consider their needs to be comfortable on their gardening plots.

It is known that one out of every ten people walking down the street is left-handed. In daily living, left-handed people come across hardwares and facilities that were designed for right-handed people. Most tools, utensils, office equipment, home appliances, clothes, medical instruments, sporting goods, weapons, and public facilities are made for the right-handed person. Many left-handed people thus have trouble with living in our environments. In this study, 1,933 Korean male and female subjects aging from 10 to 82 were selected to investigate the various statistics about hand dominance and their employment characteristics of preferred hand in handling diverse products and facilities. The statistics showed that 5.6% were left-handed and 7.6% were ambidexter. There were strong tendency that left-handed people use more left hand when take action that force is required than when take exquisite action. Ambidexter and right-handed people use more right hand when they take exquisite action is required than when take action that force is required. It was found from these results that people use their hands differently depending on the hand dominance when they handle things, hence this should be considered in designing hand control devices.

EMF (Electromagnetic Field) is a valuable resource for living in a knowledge-based information society. The EMF is used in home appliances that make our lives easy and convenient, and in telecommunication devices such as mobile phones, personal computers, medical devices and broadcasting towers. However, the biological hazards associated with EMF exposure are also increasing in signal from telecommunication devices. Studies of the effects of EMF exposure on humans have been conducted for a long time, but it has not yet been demonstrated whether the EMF effect is harmful. In this paper, we examine the electromagnetic field emitted from various electronic devices around living and its effect.

The extensive coverage and high speed of communication network, which is a basic structure of the information society, enables the provision of various forms of informatiov. especially, such services as cyber medicine, cyber education, home office, home banking, and home shopping will be common; and, now, no one can deny that the information society starts to be part of our life. Regarding home office, John Navigate predicted home office through the electronic house in New Mecca Trend and Alvin Toffler asserted in The third Wave that people could do their work anywhere including living room in their hoses with the development of communication technology and other related appliances. Such predictions are realized with the development of information communicatiov. Therefore, housing space should be changed according to the realization of home office and the direction of housing plan need to be set for home office.

Recently the idea of a home automation has been an important issue in many publications and home appliances companies. Home automation is a house or living environment that contains the technology to allow devices and systems to be controlled automatically. Remote and local control are useful to keep home comfortable and to support the elderly and the disabled people. In this paper, we discuss possible developments of Bluetooth wireless technologies and describe the hardware for devices and software for the considerations of a home automation system. Finally, we have validated the testbed by simulating in the Bluetooth home network.
