Recently, the concern of aging society is 'Healthy life' for the elderly and pre-elderly. Especially, realizing the 'Healthy life', it is very important for the elderly to establish living environment for holding and maintaining mental depression. Mental depression is related to dysfunction of sensory organ included physical functions. Therefore, the dysfunction of elderly's sensory organ is required to the guideline of environmental planning. In this study, among five senses, I focused visual sense due to the large proportion of environmental perception. The purpose of this study is to analyze the degree of geriatric depression and preference of simulated images applying preferable color for the elderly. This study conducted literature review and questionnaire survey. Firstly, the previous studies related with the melancholy, sense of isolation, self-regard for the elderly analyzed. Secondly, the questionnaire tool measuring the degree of geriatric depression developed. Thirdly, the tool investigating the preference for the simulated images applied main, sub, and accent colors produced. Applied preferable colors were used from the results previous study. Lastly, based on the result, the basic data of color planning were suggested. It was judged that this study is an useful as the basic guideline of color planning for the elderly's residential spaces and the potential value of considering geriatric depression and the color planning in terms of the elderly's visual sense.

Model gel food samples of yanggaeng (Y) were prepared for the elderly with various gelling agents, including agar (AG), low acyl gellan (GL), ${\kappa}$-carrageenan (CA), locust bean gum (LB), glucomannan (GM), and xanthan gum (XA) in different combinations as follows (in 1:1 ratio): LB+CA, GM+XA, and GM+CA. The quality characteristics of the different combinations were compared. The results revealed that water loss was highest for Y-GL, whereas there was no significant difference among the other samples. Y-GL showed the highest values for lightness in color, whereas Y-AG showed the lowest. Regarding textural properties, Y-LB+CA had the highest hardness value, whereas Y-GL had the lowest; the hardness of Y was related to the cross-section of the added gel. Finally, Y-GM+XA exhibited the highest score in overall acceptability in the sensory test by elderly, indicating that the preferable texture by elderly is slightly chewy, but not adhesive.
