Recently, South Korea is reaching aged society through ageing society. Accordingly, facility related to aged is increased consistently because of effort to improve the welfare of the elderly through elderly long term care insurance in 2008. however, the number of fires in the elderly facilities is increasing rapidly too. It is becoming bigger and higher and the characteristics of person who is unable to afford are mostly having difficult evacuation. so fire safety guildelines are urgently needed but korea research is insufficient. In this study, we propose a fire scenario through investigation of fire causes for fire safety guideline development of elderly facility, and describe to the fire safety countermeasure.

Discourse is regarded as an important component of communication assessment, but studies about the discourse characteristics of the elderly are scant. The purpose of this study was to confirm the effects of aging, gender, and educational level on discourse in elderly people with normal cognitive function. Forty normal elderly and forty young people participated in this study. A picture description task (Boston Cookie-Theft picture) was used to examine discourse function. The description task was analyzed for both productivity (total number of sentences, total number of syllables, and syllables per sentence) and semantics (CIU ratio). The results were as follows: 1) Only CIU ratio differed significantly according to age. 2) In the total number of syllables and syllables per sentence, females demonstrate a higher number than males. 3) The CIU ratio differed significantly according to educational level. These results suggest that impairment of communicative function is an aspect of cognitive impairment that can be related to aging. Also, discourse performance in the elderly is associated with their gender and educational level.

The purpose of this study is to investigate the user characteristics in different age groups by investigating the level of satisfaction and preference of design and function of mobile phone. 160 subjects participated in the experiment. Subjects with different ages were selected and divided into four groups: young age group (20 to less than 45), $1^{st}$ middle age group (45 to less than 55), $2^{nd}$ middle age group(55 to less than 65), and elderly group(over 65). A questionnaire was developed based on the previous design guideline, and additional questions were made to test newly developed function and design of the mobile phone. In particular, depth interviews were conducted in order to have a proper response from old subjects who have difficulties in completing written questionnaire. In result, it was found that except for price the major criterion to purchase mobile phone was the design, and the function of phone was the next except for elderly group. In the case of elderly group, the screen size is the first. Statistical results indicated that 37.5% of the young age group, 22.5% of $1^{st}$ middle age group, 22.5% of $2^{nd}$ middle age group and 10.0% of the elderly group preferred the design to function when they purchase mobile phones. Most elderly people were not satisfied with the supplementary function of the mobile phone. The $1^{st}$ middle age group did not know exactly how to use the supplementary service although they were willing to use it. Regarding the emotional preference on the type of phone, the sliding type was preferred most. Current results can be used to anticipate the future trend of mobile phone and design a user-friendly product for the aged population.

Korean society is changing into aged society with the speed which has never happened by other countries before. This has been the consequence of low birthrate and Increase in life expectancy. However, such social problem result in many studies on elderly environment. The purpose of this study is to systematically analyze empirical studies on elderly environment in Korea, find out research streaming and understand social backgrounds. For this study, content analysis was conducted. Articles of 4 registered academic institute published from 1986 to 2005 were units of analysis. Using keyword through library database systems, the articles were systematically selected. As results, trends of research according to 4 periods were identified. Among them as major trends, expansion of the quantity, expansion to Intoner design, more facilities for dependent elderly appeared. This result showed implications on interior design education and research for aging friendly design.

The aim of this study is to conduct superordinate word selection task to compare their performance and reaction time, and superordinate word writing task to compare the differences in their performance and error pattern in 40 elderly adults and 43 young adults. As a result, first, in both tasks, elderly adults had a smaller number of correct responses. Second, elderly adults showed slower reaction time than young adults. Third, in superordinate word writing task, elderly adults showed more relevant errors than irrelevant errors. The reason elderly adults had a smaller number of correct responses in both tasks was that the links among the pieces of information in the semantic lexicon weakened or deteriorated due to normal aging. Slower reaction time was based on neurophysiological changes of the brain and cognitive processing speed. In addition, the relevant errors showed that they could access the lexicon for target words and produce explanation the relevant characteristics, even though they could not retrieve the target words.

The purpose of this study was to investigate the relationship between physical activity, diet and mental health of elderly and to use the study as basic data for a program development for elderly. This was a secondary data analysis study using the 2015 National Health and Nutrition Survey and the study subjects included 1,484 individuals aged 65 and over. The results showed that depression and stress perception in young-old were higher than old-old's and the suicidal ideation rate of old-old was higher than young-old's. In case of eating patterns, 'poor eating' in old-old was higher than young old's. Regression analysis showed that middle-intensity physical activity and eating patterns were associated with mental health of the elderly. Based on the results, it is necessary to develop a differentiated nursing intervention program suitable for the elderly by age.

This study aimed to compare and evaluate nutritive conditions of the female elderly (2,893 people) based on a national health nutrition survey and health-related factors influencing nutritional intake. The results are as follows.- Average age of all subjects was $72.12{\pm}5.2$ old. BMI ($24.48{\pm}3.3kg/m^2$) and waist size ($83.9{\pm}9.5cm$) of urban elderly was larger ($23.74{\pm}3.3kg/m^2$, $82.28{\pm}9.9cm$) than that of rural elderly. MAR[4] and MAR[10] were also higher in urban elderly than rural elderly. The results of multiple regression analysis showed that factors influencing poor nutrition of elderly subjects were increasing age, smoking, and self-rated health. Old-old and current smokers were associated with a higher likelihood of poor nutrition (OR 1.82, 95%CI 1.43~2.30) and (OR 3.40, 95%CI 2.17~5.33) elderly female subjects in urban areas. Smoking (OR 2.29, 95%CI 1.33~3.95), poor self-rated health (OR 1.55, 95%CI 1.11~2.16), over nine hours of sleep per nighting (OR 1.72, 95%CI 1.17~2.53) and stress (OR 1.46, 95%CI 1.10~1.92) of elderly female subjects in rural areas were associated with higher likelihood of a poor nutrition. In conclusion, rural elderly are more influenced by poor health practice behaviors (self-rated health, sleeping stress) and psychological factors. Nutrition status of the rural elderly is worse than that of the urban elderly. To reduce nutritional risk of Korean elderly, especially rural elderly, active nutrition arbitration should include psychological environmental factors.

The purpose of the present study was to investigate the differences of nonlinear characteristics of electroencephalogram (EEG) depending on different sensitivities of behavioral activation system (BAS) and behavioral inhibition system (BIS) of young and elderly groups. The EEGs from Fpl and Fp2 electrodes were recorded during resting condition. The young and elderly groups consisted of 19 and 31 healthy right-handed volunteers, respectively. We estimated 1/f scaling exponent which reflects the nonlinear dynamical complexity of EEG. As results, we found the differences of 1/f scaling exponent between young ant elderly BAS sensitive groups. The 1/f scaling exponent of young BAS sensitive group showed significantly higher values than those of elderly BAS sensitive group at the left prefrontal area (Fpl). The young BAS sensitive group had also a tendency to higher 1/f scaling exponent at the right prefrontal area (Fp2). Decrease of the 1/f scaling exponent indicates the increase of complexity and the decrease of the amount of information related to the statistical distribution. Therefore, the elderly BAS sensitive group has higher complexity than young BAS sensitive group, though they were all classified as BAS sensitive group by BAS/BIS scale. Our results suggest the possibility of correlation between BAS sensitivity an4 age.

Purpose: This study was conducted to analyze the factors that influence the life satisfaction of the elderly according to their cognitive impairment level. Methods: This study was conducted by dividing 3,012 elderly residents of a regional community into three groups based on the scores of the Korean version of the Mini-Mental State Examination: a normal group without any cognitive impairment, a suspicious group with a mild level of cognitive impairment, and a high risk group with a high level of cognitive impairment. Researchers made phone calls, house calls, and personal visits to health centers and shelters for the elderly to gather the information required for this study. Results: The results of this study revealed that social relationships, depression, and activities of daily living had a significant impact on life satisfaction for the normal group, while social relationships and depression had a high impact on life satisfaction for the suspicious group, and social relationships had high impact on the life satisfaction of the high risk group. Conclusion: Based on the results of this study, we suggest that programs that promote development of the social relationship networks of the elderly should be established to promote their life satisfaction.

Objective: The aim of this study is to set the design direction of the lift chair's tilting seat for development. Background: Great attention has been shown to the development of senior friendly product, because of increasing elderly population rapidly in Korea. Therefore, we need to study on sit-to-stand(STS) motion of elderly systematically for developing lift chair that is one of senior friendly products. Method: In this study, we analyzed joint moment(knee, hip) and muscle activity (Erector spinae, Rectus femoris, Vastus lateralis) on STS motion of elderly(female, 60~70: 7) and young people(female, 20~30: 7) using 3 dimension motion capture camera, force plate, wireless EMG. Results: The results of muscle activity showed a similar trend but the results of joint moment were a lot of differences between the young and the elderly. Conclusion: The results of knee joint moment suggest the angle(10~30deg)-adjustable seat that can be better than to find the optimal seat's angle. Application: The method and results of this study are expected to develop senior friendly product and verification as well as be available to various application.
