The aim of this study was to identify essential oils (EOs) and their concentrations that improved the sensory characteristics of Kochujang by analyzing the effect of the essential oil on the sensory characteristics of Kochujang. EOs from Chrysanthemum indicum, Chrysanthemum morifolium, Zanthoxylum piperitum and Zanthoxylum schnifolium, which have an outstanding flavor, were added to Kochujang and the resulting products were subjected to sensory evaluation as a function of storage period. The change in the color of Kochujang by the addition of these EOs from Chrysanthemum indicum, Chrysanthemum morifolium, Zanthoxylum piperitum and Zanthoxylum schnifolium was not observed. Kochujang's characteristic flavor was decreased by an increase in the concentrarion of EOs; however, no significant difference was observed when 0.0005% EOs were added relative to the none-additive groups (p<0.05). EOs addition did not affect the hot taste of Kochujang and as the additive quantity increased Kochujang's characteristic taste significantly decreased (p<0.05). After a storage period of 12 weeks, the overall preference of Chrysanthemum indicum, Chrysanthemum morifolium, and Zanthoxylum piperitum was same as the none-additive groups (p<0.05). Therefore, it is suggested that EOs from Chrysanthemum indicum, Chrysanthemum morifolium, and Zanthoxylum piperitum can be applied as additives to improve the characteristic taste and flavor of Kochujang and the recommended concentration level is 0.0005%.

This study compares results of evaluation pertaining to the emotional vocabulary of the visual perceptive spaces, targeting residential space to analyze the correlation of the diverse visual perceptive spaces centered on the emotion. The results of the analysis are as follows: First, it is possible to know that the correlation of visual perceptive spaces can be identified centered on the vocabularies that serve the measure for emotion. These results demonstrate that one visual perceptive space, developed with perspective illumination can induce another visual perceptive. Second, when the correlation analyzed for each visual perceptive space is examined, it is possible to know that the extended spaces are correlated to the deep spaces while there are no visual perceptive spaces that manifest relatively high correlation when it comes to the deep spaces. Boundary spaces manifest correlation of the negative with the extended spaces while overlap spaces manifest correlation of the negative with the boundary spaces. Central spaces manifest correlation with the formativeness and boundary spaces while formative spaces manifest correlation with the centrality and boundary spaces. Through this, it is possible to know that all the visual perceptive spaces are mutually correlated. Third, when the correlation of visual perceptive spaces is identified, there is a difference in the number of visual perceptive spaces that are correlated and the degree of correlation. Accordingly, given the emotion of the diverse users, it is effective to plan by leveraging visual perspective that manifests correlation with numerous visual perceptive spaces. Lastly, study results are expected to be used for the planning for the interior spaces that factor in the emotion, and this study intends to serve as the basis for the future study on the emotion and behavior.

The purpose of this study is to analyze the change of visual stimulus of users to the space through the experiment of EEG and the satisfaction of users depends on the lighting. To do that the results measured with EEG experiment focusing on Beta β were compared to each other to figure out difference in the changes of the activation of human brain on lighting`s situation as the lighting off and on in the same space. The difference in the results was verified according to the characteristic of users which classified with 4 types of the spatial sensitivities. The results of this study are as following. Firstly, the spacial sensitivity of user is to communicate well with the different senses with stimulus through interaction among the elements. At this time, the brain plays a major role in build the spacial sensitivity of users as the place to make form. Secondly, there are the differences in the activation of brain depends on lighting situation even in the same space. The stimulus into the brain became generally stronger in images with lighting on than off. Especially, the response in the occipital lobe which connected with the visual center turn out strongly in the image of `modern natural`. Because the visual stimulus interact well with the bright color, the reflectional texture and the rough texture painted the dark color. Thirdly, the satisfaction of users changed with lighting in the space. But we could know that the satisfaction of users isn`t be related to the visual stimulus through the results of this study. Finally, there isn`t the difference in the activation degree of brain according to the characteristic which are preference of users into 4 types of the spatial sensitivity through the results came from ANCOVA(analysis of covariance) with SPSS Program 22.
