This study is performed to improve the elevation design of schools by the tools of color. Color is a very powerful design tool, one that is capable of altering the perception of a building or a space. The present form and material of elevations of schools are very monotonous and uniform. Therefore students do not have attachment for schools. And also in neighborhood, schools do not function as a good landmark. This study aims to develop good sample of exterior color design for schools and verify the guideline of color design for schools which was went ahead of this study. Through the survey of color preference and color image preference of the students of Seoul High School, the attitude of students to color were considered in design. The exterior color design for Seoul High School was realized. The result of this study suggests that the exterior color design can improve the image and plasticity of present schools. But within the monotonous character of present elevation, the effect of color design will be limited. Therefore to make a effective project, exterior color design should be accompanied with the alteration of elevation to make a plastic element of elevation.

The energy absorption characteristics of diamond core sandwich cylindrical columns under axial crushing process depend greatly on the amount of material which participates in the plastic deformation. Both the single-objective and multi-objective optimizations are performed for columns under axial crushing load with core thickness and helix pitch of the honeycomb core as design variables. Models are optimized by multi-objective particle swarm optimization (MOPSO) algorithm to achieve maximum specific energy absorption (SEA) capacity and minimum peak crushing force (PCF). Results show that optimization improves the energy absorption characteristics with constrained and unconstrained peak crashing load. Also, it is concluded that the aluminum tube has a better energy absorption capability rather than steel tube at a certain peak crushing force. The results justify that the interaction effects between the honeycomb and column walls greatly improve the energy absorption efficiency. A ranking technique for order preference (TOPSIS) is then used to sort the non-dominated solutions by the preference of decision makers. That is, a multi-criteria decision which consists of MOPSO and TOPSIS is presented to find out a compromise solution for decision makers. Furthermore, local and global sensitivity analyses are performed to assess the effect of design variable values on the SEA and PCF functions in design domain. Based on the sensitivity analysis results, it is concluded that for both models, the helix pitch of the honeycomb core has greater effect on the sensitivity of SEA, while, the core thickness has greater effect on the sensitivity of PCF.

Recently, though mulberry's superiority as a functional food has been proven, its use as a food material is limited. Therefore, in this study, to develop jelly using mulberry that is compatible with Korean tastes as health functional food by grafting the method to manufacture jelly consumed as a dessert or a snack in the west, according to the central composite design, mulberry jelly was produced by varying the content of citric acid ($X_1$), sucrose ($X_2$), and gelatin ($X_3$) at 5 levels. And by applying the response surface methodology, rheology and sensory preference experiment results were analyzed, the optimization of mulberry jelly manufacturing condition was carried out, and studies on the analysis of composition were performed. As the sensory preference of mulberry jelly, except the flavor, the remaining hardness, elasticity, sweetness, color, and the overall quality were found to be significant. And similarly, it was found to be influenced greatly by gelatin content generally. Based on the overlapped part of categories, in the range of factors that satisfy all the sensory categories, the value located in the middle was calculated, the optimization point was obtained, and it was found to be 6.2 g citric acid, 141.0 g sugar, and 13.5 g gelatin.

This study was performed for 235 caddies of 5 membership golf clubs in Jeonnam area to find out their attitude and usage, satisfaction and preference on uniforms $1^{st}\;to\;15^{th}$ February 2007. The result of the study could be summarized as fellows. First, 69.7% of them affirm in the inquiry of 'to feel belong' and 'to tell from others', but they showed low affirmation in other inquiries. In the case of satisfaction of wearing uniforms, they show low satisfaction in most categories such as design, color, materials, activity, and symbol. Second, the most favored color coordination is the two color coordination in the upper and bottom uniform, and the fevered design pattern is the no-pattern one with single color. The favored uniform constitutes a jacket and a trouser in spring through fall, and a parka long enough to hip line, a polo neck, a vest, and a trouser in winter Third, activity is the most important considering factor in the choice of uniform and is also the most improve-wanted factor in the presently wearing uniform. The most important factor in the characteristic of material is absorption of sweat, but there is especially high dissatisfaction in absorption. It shows that there are demands of functional design considering caddies' working environment and activities. Differentiated from other normal uniforms, the uniform should be improved for caddies to develop their specialty and to feel wearing satisfaction.
