Kitchen cabinets are widely used for their spacious storage and efficient use of space, but their high installed location makes it difficult for the elderly and disabled to access. Therefore, in this paper, we propose a new height-adjustable kitchen cabinet that can be used more easily and safely. The lift-down range of cabinet was set considering the installation location of cabinet for efficient use of kitchen space and the maximum height accessible to the elderly and disabled, and the link geometry and driving method of the complex link mechanism were determined through the mechanism design procedure to ensure that the selected floor come down safely along the optimal descend path. In addition, the appropriate motor and control algorithm were added to allow the user to descend to the desired height with a simple button operation. It was confirmed through actual production that the proposed linkage mechanism performs the desired lift-down motion.

This paper describes the development of a walking assistive robot for effective self-rehabilitation for elderly people facing an inconvenience in walking. The main features of the developed robot are enhanced safety and mobility using the baby walker and electric wheelchair mechanisms and an accurate walking tracking control algorithm using potentiometers and stereo cameras. Specifically, a pelvis supporter is designed to prevent the user from falling down and reduce the burden on their legs, and electric motors are used for easy locomotion with low effort. Next, the walking intention and direction of the user are automatically recognized by using potentiometers attached at the pelvis supporter so that the robot can track the user, and the rapidity and accuracy of the tracking were increased by applying a lower-body motion analysis algorithm with stereo cameras. Finally, the user-tracking performance of the developed robot was experimentally verified through stepwise walking assistance experiments.

The era of Web 2.0, which is the web environment that offers end user oriented web platform, has arrived. Moreover, as the interest in UCC (User Created Contents) environment increases, it is a fact that the involvement of the users in multimedia contents is increasing rapidly. When the aim of Web 2.0, i.e. active involvement of the user, is considered, the necessity and the understanding about accessibility problem of the people who have difficulties about accessing web information, such as elderly and visually handicapped people, is increasing as well. This research analyzes the problems of virtually handicapped users to access web-based UCC services, and proposes an efficient implementation plan for a web-based UCC service that enables smooth access for them. Especially, the validity of the proposed method was verified by comparing the reaction time of the visually handicapped users with that when using the existing UCC services, through the implementation of the test page according to the plan proposed in this research.

This study aims to explore social participation needs among the elderly in Korea from the perspective of the elderly participant's. 40 Q-samples are drawn from the Q-population including attitudes and needs toward social participation in later life based on news articles, essays, research, documentary, and television shows. 35 subjects are analysed by the QUANL program and the types of social participation needs are divided into four patterns which accounted for 60.16% of the total variance. The elderly's portrayal of an ideal social participation is about making independent decisions and being able to actively participate in the activities they chose to do. However, their most undesirable scenario would be being confused and uncertain of what they should do the remainder of their lives. The needs of social participation among the elderly varies on four indicators such as ego, social capital, life satisfaction, life vitality and these four indicators have two sub-categories with a total of 8 types of classification. These 8 types differ by priorities, adaptation to life changes, motivation to social participation, and desired activity. Findings suggest that researchers and policy makers need to consider service user perspective on social participation in later life, not service provider perspective.

The purpose of this study is to classify the quality attributes of service quality for the elderly in public libraries, derive satisfaction coefficients and dissatisfaction coefficients, and present the priority improvement of service quality. To this end, a survey was organized with 22 questions from LibQUAL+ for elderly users who use library in uiseong-gun, gyeongsangbuk-do. Quality factors for service were classified into three areas of LibQUAL+ based on the kano model, and the satisfaction index and dissatisfaction index felt by users for each service quality were calculated through timko's customer satisfaction coefficient. Based on this, a Potential Customer Satisfaction Improvement index (PCSI index) was obtained to determine how much user satisfaction can be improved when actual requirements are met. As a result of classification of quality attributes of service quality, it was classified into 9 attractive quality, 7 one-dimensional quality, 1 indifference quality, and 5 must-be quality. In the improvement ranking for service, the first place was 'making electronic resources accessible from my home or office', the second place was 'print and/or electronic journal collections I require for my work' and the third place was 'a library web site enabling me to locate information on my'. It is expected that the study results can be used to present quality factors that should be managed and improved first when providing services for the elderly.

Gyeonggi Province has established a bus information system to provide real-time bus arrival information, aiming to make bus usage convenient for its residents. While the Gyeonggi bus information system is becoming more advanced through the application of IT technology, there are still information-vulnerable groups finding it difficult to use. In particular, the elderly have a low level of digital information literacy and habe difficulty using it. In this regard, this study aims to address the information usage disparity among the elderly in public transportation by utilizing expert in-depth survey methodology known as the Delphi technique. The study classified the policy initiatives that Gyeonggi Province should undertake into three categories: user education and expanded promotion, technological development and dissemination, and providing convenient usage environment. Through two rounds of surveys, the study assessed the priority of ten specific sub-tasks within these categories. Additionally, it gathered opinions on the effectiveness and feasibility of each item. The results yielded prioritization and evaluation of effectiveness and feasibility for nine sub-tasks. Based on these outcomes, the study proposed future projects that Gyeonggi Province should implement to address the information disparity among the elderly, offering a comprehensive approach to bridge the gap.
