We suggest the development of a mobile muscular savings account application as a more effective and consistent strategy to avoid sarcopenia, one of the elderly diseases, based on the researcher's experience conducting a handwritten 'muscle saving account' in the S city of the metropolitan area. The analysis of currently existent healthcare-related applications shows that muscle strength improvement and maintenance applications are needed to improve easy use and access without burden for elderly users because there are many functions, and it can be difficult for the elderly to use the application. A survey of participants who used handwritten 'muscle savings accounts' was conducted before the design development to measure user satisfaction. Based on this, the suggested application's design is similar to the handwritten type, functionalities are modified for easy usage by the elderly, and information is intuitively comprehended and presented properly using color contrast and Sans serif font. We plan to conduct a survey of the elderly who did not participate in the project as part of follow-up research, and afterward continue the research on the development of customized applications optimized for the prevention of sarcopenia in the elderly for muscle strength improvement and maintenance based on the results.

Since the proportion of elderly citizens is increasing every year, the social interest is increasing for the health and the safety of the elderly. The nursing home is continually being created to care for more elderly people. However, the quality of service is not enough due to the lack of elderly caregivers. Elderly care and management services are being studied to replace the shortage of caregivers. Existing research for the implementation of an automatic care system has a high initial system cost. Furthermore, it lacks the ability to store and manage large amounts of data. In this paper, we propose a system that manages a large amount of data continuously generated through CCTV and provides a streaming service with a high level of quality-of-service (QoS) to users with collected video. Through the proposed system, it is possible to record and manage the behavioral information of the elderly occurring in the nursing home together with the video. In addition, according to the user's request, it has built a service that streams the video and behavioral information according to the date and time in real-time.

This paper describes the development of a novel walking assistance robot for the elderly and infirm. In the case of simple walking assistance devices, the walking safety and effectiveness are somewhat low; hence, caregivers are frequently required. The walking assistance robot developed in this research is capable of securely and conveniently assisting a walking user by using electric motors and various devices without a caregiver. The main features include the following. First, the walking safety is improved by using a pelvis supporter, and the robot is able to follow the user effectively by means of ergonomic motion sensors and electric powered wheels. Second, it is possible to adjust the load applied to the lower body by adjusting the height of the pelvis supporter. Finally, it is possible to inform the approximate distance and direction of any obstacle around the robot using the sounds and vibrations for the blind and the hearing impaired. The performance of the developed walking assistance robot was successfully verified using a walking assistance test in a narrow-corridor environment.

The number of elderly people is increasing rapidly in Korea. A large part of their information seeking behaviors are changed form a few conventional types of media such as letters to computers and Internet. Their use of computers and Internet, however, was difficult due to various problems including the interface especially. This work has examined and analysed the basic elements and components of interface design for the elderly people into the previous papers. The result of the study would be applied to the public libraries for the elderly and the interface design within the institution.

The purpose of this study was to evaluate performance and subjective satisfaction of mobile phone's interface elements considering the elderly users. First, mobile phone's interface elements were outlined recent foreign and domestic studies. Then, final three mobile phone's interface elements were determined by expert rating, AHP analysis, and questionnaire analysis. Objective and subjective measures were then used to determine the effects of several specific design parameters and aging differences on performance of mobile phones. In this experiment, 38 subjects and 4 independent variables were used to measure task completion time and user's subjective satisfaction. The statistical analyses indicated significant aging differences between older people and younger people in terms of keypad type and bell sound level in performance. Significant aging differences were also found for user subjective satisfaction. It is suggested that some major results from this study be used to develop mobile phone design guidelines that are more usable and accessible for most users, particularly for older users.

According to the OECD Report, Korea passed the first threshold to an "aging society" in which the elderly aged over 65 make up at least 7 percent of the population in 2000, and in 2018, are due to pass the second to an "aged society" in which they make up at least 14 percent-just 18 years later. It took France (starting in 1864) 115 years to complete this transition. Even Japan, legendary for the rapidity of its aging, required 24 years. It means Korea has to prepare for the aging of its population within a very short time without mistakes. Meanwhile, in a 2005 survey of the elderly, 85.5% of them preferred aging in place to moving to elderly care facilities. That means housing planning for the elderly which provides them with independent living needs to be considered seriously. The digital technology integrated home may be one of the alternatives to support this idea. In order to find a way to user oriented digital homes for the elderly, this study identified the their needs on the physical features of the ideal home and the digital services necessary through digital life scenarios.

Elderly women have a high risk of falling down in their daily lives. The purpose of this study is to develop protective pants for elderly women, which will mitigate the impact of falls, and play a major role in reducing injuries. The two types of design were proposed for development of protective pants by selecting pad insertion point and inserting lining for keeping pad in place through the checklist to investigate from the interviews with the medical workers and the investigation of the user requirement. Design A has protective pads in the hip, hip joint, and knee, while design B has protective pads in the hip and hip joint area. For the impact absorbing material, CR (chloroprene rubber) foam was selected for its flexibility, lightness, and impact absorbing capacity, and its pad shapes were designed to produce much flexibility in consideration of the activity and human body fitness of the wearers. Three kinds of pad types, which are the cut type, the porous type, and the honeycomb type, were proposed, and were manufactured to fit into the protective parts according to their design types.

Background: The objective of this study is to evaluate the relationship between chewing ability and health status in order to provide basic information for the development of program which may lead to an improvement of a the elderly health status in urban areas. Materials and methods: The subjects of this study were 128 elderly urban female over the age of 65 who reside at house. The data were collected from May 21 to August 20, 2001, through questionnaires about nutrient intake status, direct measurement of anthropometrics, and oral examinations. Results: In terms of remaining teeth, there was significant negative relationship between age and number of remained teeth. The average number of remained teeth our subjects was $13.1{\pm}10.6$. About sixty five percent of the subjects were denture users (partial or full dentures) and there was positive relationship between age and the percentage of denture user. There was a significant negative correlation between age and chewing ability. The group that was able to chew had more remained teeth than the other group. Conclusion: This study suggests that there is strong positive relationship between chewing ability (remaining teeth) and elderly health status in urban areas, and the importance of preserving original teeth to improve the elderly health status in the public health program.
