The number of elderly citizens has risen in Korea and resulted in an aging society. Correspondingly, the social interest in the aging population has escalated immensely; however, research or product development on the quality of life for seniors has shortcomings. Healthcare smart clothing is required to help the elderly with changes and weaknesses that follow aging; however, there is unfortunately insufficient amounts available. This study explores the feasibilities of smart clothing for seniors based on a universal design. Based on previous research, we analyzed the universal design theory, body shape characteristics and design requirements for seniors, and heart rate measurement method. The design is different according to body shape and body shape is different between sex, age, and body race; therefore, subjects were limited to 70-74 year old Korean males in this study. This study proposes a guideline for heart rate sensing clothing that satisfies the 'universal design' aspects as well as the functionality of heart sensing, senior's physical characteristics and needs. It has broadened the range of smart clothing, which was once limited to the younger generation and provided a foundation for the development of specialized smart clothing for seniors.

Korea's aging population is rapidly increasing, but there has been little research into senior-friendly foods. Therefore, this study aimed to provide basic data for the development of senior-friendly Home Meal Replacement(HMR) foods by conducting a survey among elderly and middle-aged persons highly likely to purchase senior-friendly foods in the near future. Study findings showed that the level of HMR purchase was higher among the middle-aged, many subjects preferred products requiring simple cooking, and a higher proportion of subjects purchased them offline. Five HMR selection attributes were identified, and dietary lifestyles were classified into four categories. Through a cluster analysis, 3 groups based on level of involvement were identified: high-level, mid-level, and low-level. Napping^® analysis showed that subjects classified food products into HMR and meal kits, and into products with a clear broth and products with a thicker broth. The study findings are expected to help suggest a differentiating approach in developing senior-friendly HMR foods.

Since aging has become one of most hot and serious issues in the whole global world, universal design as a strategic concept to enable the elderly age in place has received much attention and its importance is getting recognized. Japan has undergone the Aging phenomenon much earlier than Korea and other countries. During that time, through much trials and errors, it accumulated the wisdoms and techniques to precede aging friendly environment and products. Therefore current Japan house is a comprehensive setting which embraces lots of universal design features that has a valuable implication for Korean development that faces fast aging future. The purpose of this study was to delineate characteristics of universal design features appeared in Japanese Model houses. One site of housing park in the city where various model houses of representative housing construction companies was selected as a cluster area for data collecting. Data were collected mainly through field survey at the housing park of Tokyo during November, 2006, and additional data were collected through website and company information of relevant company. Universal design features were extracted for 17 houses of the housing park and sorted and analyzed according to the analysis frame. The frame were made using 2 major clusters; space area, and 8 universal design principle. Results showed a range of universal design feature and its detail universal design principle satisfied. The 8 principle currently developed became to house realistic practical examples and theory became proved its impractical power. The academic, educational and industrial implication were documented.

Since 2000, Korea has seen a big trend in the market, as the EU tightened regulations on environment due to global warming, high oil prices and aging rural population distribution, strengthening the need for multi-purpose electric moto vehicles for small farmers based on eco-friendly energy. Multi-purpose electric motor vehicles for rural small businesses will be a very innovative means of transportation, not only maintained at a low cost and to reduce greenhouse gases through the activation of eco-friendly energy, but also be a very innovative means of transportation for reducing the labor intensity of the aging farming industry and transporting night work and logistics. In this paper, with the implementation of eco-friendly energy policies, small and medium-sized rural small business owners can easily operate on unpaved roads and well-drawn farming environments, while the intensity of labor can be reduced when transporting crops also can simply replace parts at a low cost in the event of an accident. To propose rural multi-purpose modular electric vehicles, the existing literature is reviewed and 12 modular parts are presented by benchmarking electric vehicles at home and abroad. This paper is thought to be helpful for the research of the industry as well as the design industry of modular electric vehicles.

One of the most effective ways of preventing skin aging is to protect the skin from UV radiation, which was identified as the primary cause of photoaging. Therefore, it is necessary to develop natural and environment-friendly materials to the human skin. This study examined the effects of MAAs extracted from Chlamydononas hedleyi on UV protection and anti-inflammation in human skin cells. The function of porphyra-334 in the skin, which was isolated and purified from MMAs mixture, was tested in terms of its UV protective ability and anti-inflammation. As a result, porphyra-334 played a role in protecting the skin from UV radiation and anti-inflammation through the suppression of COX-2 expression. These results suggest that porphyra-334 can be a useful material in cosmetic products because it can protect the skin from UV radiation and anti-inflammation.
