Village community centers are public locations where residential members of communities gather for various group meetings, social support, public information and recreational activities. Since the residents voluntarily operate the facilities, a convenient access to the center is a very important criterion for choosing where such facilities should be distributed throughout the districts. In particular, it is highly desirable to locate them within walking-distances from the residential populations. In this work, we have evaluated the accessibility to the community centers in several rural areas based on the surveys that were collected from year 2005 to 2012. We used the collected rural amenity resource distributions of the area for the evaluating the accessibilities to village center. More specifically, we considered some factors such as residential district and fraction of elderly population in the vicinity.

Quadruped robot is very useful mechanism for a various area. Recently, home entertainment and military robots adapted quadruped platform and useful function have been introduced. Our goal is the development of quadruped robot locomotion for any type of ground included to sloping one and irregular terrain. This paper, as a first step, deals with design and construction of quadruped robot walking on the flat ground. The most important factor of quadruped robot is stability of locomotion. At first, we introduce the developed quadruped robot based on dynamic simulation and experimental study of general gait algorithm. Finally, propose unique locomotion proper to our mechanism. Future work of this study is the performance test and analysis on the ground of various conditions and proposes the improved mechanism and gait algorithm.

The purpose of this study were to examine actual conditions of apartment residents living with their companion animals and to identify their residential stress and needs of planning elements under those conditions. Questionnaire survey was adopted in this study, and 100 cases were used for data analysis. The subjects for this study were limited to the residents breeding pets in their apartments. The results of this study are as follows: Most of the residents share their living spaces with pets together like their family without spatial restrictions. They indicated problems related to breeding pets in their residence such as walking the dog, cleaning home, leaving pets alone, noise and unpleasant smell. However, they didn't seem to be stressed a lot for their living environments. In terms of residential planning elements, floor plans for effective natural ventilation, balcony with sufficient sunlight, sound proof system, easy-maintenance interior material, unlash area, rubbish bin, mechanical ventilation and central vacuum system and safe electric outlet were highly indicated.

This paper describes the detection of spatio-temporal parameter using an accelerometer and footswitches to evaluate a symmetry and balance of hemiplegic patients. We detected gait data using a 3-axis accelerometer that mounted between L3 and IA intervertebral area and footswitches made by FSR-Sensor attached insole. To minimize the error of the gait parameters to be detected incorrectly in case of using only accelerometer, we enhancement the performance of detection by measuring an accelerometer and foots witches data at the same time. So, it was possible to detect more accurate gait parameters. As a result, we can confirm the symmetry and balance of hemiplegic patients. In the future. these results could be used to evaluate the walking ability in hemiplegic patients in clinical pratice.

The global positioning system (GPS)-enabled mobile phones provide location-based applications such as car and pedestrian navigation services. The pedestrian navigation services provide safe and comfortable route and path guidance for pedestrians and handicapped or elderly people. One of the essential components for a navigation system is a spatial database used to perform navigation and routing functions. In this paper, we develop modeling and categorization of pedestrian path components for smart tour guide services using the mobile pedestrian navigation application. We create pedestrian networks using 2D base map and sky view map in urban area. We also construct pedestrian networks and attributes of node, link, and POI using on-site GPS data and photos for smart pedestrian tour guide in the major walking tourist spots in Jeju.

Smart mobile robot is a kind of Intelligent Robot. It means that operates manipulate autonomously and recognize the external environment. Smart mobile robot moving mechanism has many type and the type depend on the robot shape or purpose. Recently, research on the moving mechanism has been actively in many area. The moving mechanism divided to wheel type, crawler type, walking type, other type and the moving type choose by the kind of robot or the purpose robot. In this paper, describe the kind of moving mechanism on the smart mobile robot and the technical trend of moving mechanism of smart mobile robot.

Purpose: The purpose of this study was to compare plantar foot pressure distribution in adults and elderly according to obstacle height. Methods: Nine healthy adults and nine older adults were recruited and the subjects provided written informed consent consent prior to participation. Both groups walked and crossed obstacles with heights of 0%, 10%, 20%, and 30% of their height. Foot pressure was measured by peak pressure using the Pedar System (Novel Gmbh, Germany) during obstacle walking with barefeet in shoes. Three trails were calculated on eight areas and then averaged for data analysis. Results: A significant difference in great toe, little toes, and lateral metatarsal area was observed between adults and elderly groups, but other areas did not show significant differences. Foot pressure was increased in groups according to obstacle height. Conclusion: These findings showed that change in foot pressure distribution is more lateral in elderly in order to maintain postural control during obstacle crossing.

Recent years have witnessed a growing interest in the fields of video surveillance and mobile object tracking. This paper proposes a mobile object tracking algorithm. First, several parameters such as object window, object area, and expansion-contraction (E-C) parameter are defined. Then, a modified E-C algorithm for multiple-object tracking is presented. The proposed algorithm tracks moving objects by expansion and contraction of the object window. In addition, it includes methods for updating the background image and avoiding occlusion of the target image. The validity of the proposed algorithm is verified experimentally. For example, the first scenario traces the path of two people walking in opposite directions in a hallway, whereas the second one is conducted to track three people in a group of four walkers.

The conventional 3D graphic accelerator is mainly focused on high performance in the application area of computer graphic and 3D video game How ever the existing 3D architecture is not suitable for portable devices because of its huge power. So, we analyze the embedded 3D graphics renderer. After the analyzing, to reduce the power, triangle set-up stage and edge walking stage are executed sequentially while scan-line processing stage and span processing stage which control performance of 3D graphic accelerator are executed parallel.

This study was conducted to fine out factors related with the complains low back pain in eldery persons. The Questionnaires was done for 273 eldery persons who live in Pusan, Anyang, Ansan region from May 1996 ro April 1997. The results were as follows : 1. The prevalence rate were 49.5% and among them 20.74% were male was while 68.12% which shows high prevalance of female 2. There were no statistical significance except sex difference(P>0.05) 3. There statistical different with some factor fators which includes general health condition, the frequency of treatment, sleeping bed style, condition for future life (P<0.05). But showed no statistical significance with the other factors. 4. When compared between rural and urban area, there were some statistical difference among some factor such as ; where to treat, moring exercise frequency, walking duration, sleeping bed style, agricultural work involement, prepartory condition for future life.(P<0.05)
