The purpose of this study is to set up systematically housing adaptation items for the aged family. Housing adaptation items are classified by universal design principles. Also, this paper suggest to basic data for setting up various ranges according to each elderly people's conditions, adapting for elderly housing. Recently, in relation to the growing awareness of the ageing population, the necessity of policies for "aging in place" was emphasized by government. This paper is focused on the policy of elderly housings' adaptation for making housing for a lifetime. This new adaptation items for the elderly housing lead to the revitalization of policy ensuring housing in stock at the local authority level. In this paper, adaptation items were created after analyzing indices highlighted by previous studies related to evaluation items, design-guidelines for safety plans, designing elderly housing. The scope of adaptation items was limited to the indoor spaces of apartment due to the considerable increase of in-house accidents. To sum up, this study is aimed to set up adaptation items and then, to present the basic scheme for several users offering various ranges

This study was performed to investigate the perception and preferences regarding commercial universal design foods (UDF) made with different ingredients. A one-to-one interview was used for data collection and the survey was conducted on 41 elderly people (over age 65; males: 11, females: 30) attending senior welfare centers in Seoul. Twelve UDF samples were collected, which were widely sold in Japan. Majority of respondents prepared meals (53.7%) and ate alone (43.9%), respectively. The preferred cooking level of elderly food was "ready to eat (RTE)" (43.9%) or "ready to heat (RTH)" (43.9%) rather than fresh cut product. In most, the elderly had no problem with chewing-action (90.2%). Generally, food ingredients such as grain, meat, seafood and fruits showed higher preference than vegetable and nuts. Among 12 UDF samples, pumpkin gratin (4.17) and peach flavored jelly (4.27) showed higher preferences among tested samples on a 5-point facial hedonic scale. There were no significant differences in overall preferences of all samples by difficulty in terms of chewing and swallowing of respondents. Demi-glace sauce hamburger and pot sukiyaki were more preferred as age increased (p<0.05).

Objective: The aim of this study is to investigate the attributing factors influencing usability of the mobile phones specifically designed for the elderly users. Efforts to identify factors that cause usability problems for the elderly users in using mobile phones can provide the groundwork for changes aimed at usability enhancement and design of interfaces of mobile phones. Background: It became important to understand the behaviors and tendencies of the elderly in communication as the society became older. The problems in digital divide is contributed to mainly lack of understanding in terms of the use pattern of the elderly and lack of consideration of their characteristics in designing user interfaces of most ICT devices. Method: A total of 30 elderly users who were over 65 years in age participated in usability evaluation test experiment and performed seven different tasks using a widely accepted model of universally designed mobile phone. Their performance was compared with that of contrast group that consisted of 10 younger participants who were on their 20s. Results: It was found that the elderly users had hard times in using mobile phones, especially in keypad manipulation among search, understanding, and manipulation subtasks. Conclusion: Older users seemed to have difficulty in all the subtasks of search, recognition, and manipulation. It was suggested that designers of mobile phones need to give careful consideration into designing visual interfaces for search tasks and keypads for easier control and input for the elderly users. Application: The study is expected to provide guidelines for the universal design of mobile phones and their interfaces for enhancing usability of the mobile phone for elderly users.

Currently in Korea, Researches on universal design have been actively accomplished in various fields as not only housing and public space, but also product design and education. The purpose of this study is to analyze previous researches on universal design and to identify its research trends which might suggest the future directions of the related studies. In this study, researches on universal design were analyzed to classify the types according to research area, objects and respondents. Two hundreds twenty one papers(journal articles, theses, dissertations, etc.) which were published in Korea from 1997 to 2008 were analyzed. The results were as follows. Researches on universal design have increased quantitatively and research topics have been diverse. In the 1990s, with the introduction of universal design concept, research area focused on space design, but since 2000 researches on universal design have been expanded to apply the fashion, product design and education. In terms of research objects, the studies about evaluation and case analysis have conducted more than those about principles and planning design. With regard to research respondent, the studies for the elderly or people with disabilities and those of all people including a specific target have conducted in a similar ratio. Previous studies were contributed to expand the topics of universal design and it is time to study the applications based on previous research results for utilization and dissemination of universal design. Also it is necessary to conduct interdisciplinary studies in the field of universal design.

As the population of the aged and the disabled increases, the needs for universal design is also growing. Universal design is to design for diverse users including all ages from children to the elderly, the disabled and non-disabled, the pregnant, the tourist, and etc. This study is intended to develop the design evaluation tool and guidelines of universal design for applying to space design. In order to achieve this, four basic spaces in human living such as residential space, educational space, working space, and cultural space were selected. Then, the elements of universal design were chosen for each space. The numbers of areas in each space were 12 for residential spae, 5 for educational space, 6 for working space, and 6 for cultural space. Also, 60 elements of universal design for residential space, 53 for educational space, 36 for working space, and 46 for cultural space were selected. The field observation with photos and user evaluation survey were carried out for each space by using these elements. Finally, the elements and guidelines of universal design applied for spatial design were suggested. This consisted of 8 areas and 67 elements. This would be useful for designing space for all people.

In the design guideline for the existing elderly house, the guideline related to kitchen is very important in the secure and functional aspect. In spite of importace, the present elderly house's Kitchen plan is being designed based on foreign universal design guideline or common housing form instead of considering physical social and psychological qualities of the korean elderly. Therefore, In this study based on the guideline of the previous studies related to domestic elderly house and kitchen plan for elderly house, we found physical social and psychological qualities of the korean elderly. Acooording to these characteristics we suggested guideline on kitchen plan for Elderly House. Those suggested here will be applied to design guidelines of elderly housing on kitchen plan in future.

This study examined perceived discomforts encountered in residential facilities such as individual houses and apartments, and suggested a procedure for improving the problems in the living residence. The participants consisted of two groups of people: normal and underprivileged people; the underprivileged group was classified into 3 sub-groups: elderly people (over 65 years old), handicapped people and pregnant women. To identify inconvenient places and design factors in the residential housing, a total of 200 subjects (50 for each group) participated in the survey using the 7-point Likert scale. As a result, all the user groups mainly answered a high degree of discomfort due to narrow parking places, doorsills, and height differences between floors. The elderly, the handicapped, and the pregnant women replied that it is uncomfortable to use ramps and utility rooms. In a follow-up study, one-to-one in-depth interviews were conducted with some of the participants to analyze the detailed causes of inconvenient places and design factors. This study also suggested the procedure for solving the problems in various design factors from perspective of universal design, by considering prior studies which focused on a certain user group like the elderly. This procedure was suggested to consider as many user groups as possible at the same time. The results can be used to understand the discomforts of various user groups on residential housing. The procedure can also be used to develop universal design guidelines for the living residence.

As our society progresses rapidly toward an aged society, there is a stiff increase in the population of the aged persons who have difficulties in adjusting themselves to environments due to declines of their physical functions. Therefore, there is a great need for the concept of 'Universal Design' that demands the design of overall social structure to care for the elderly. Due to this reason, the physical function of the aged persons should thoroughly be studied for the development of rehabilitation and training equipments to help the recovery of physical functions of the elderly. Among the variety of physical functions of the elderly, visual functions, motion characteristics, hearing functions, and somatosensory functions have significant influence toward everyday lives and are physical functions to study for the construction of urgently needed physical function databases of the elderly. This study concentrates on visual functions among the variety of physical functions of the elderly. To measure various visual functions of the elderly, a measurement room for the elderly has been developed, which can mimic everyday lives and perform measurements of visual functions with subjects in seated position. The measurement items for the construction of the database were capabilities in everyday vision according to changes in arrangement of colors and light intensity and capabilities in everyday vision, color distinction, dark adaptation, and light glare against changes in contrast.
