  • In this study, emotion changes were induced by four imaginations- pleasantness, unpleasantness, arousal, relaxation and it was examined using subjective evaluation and analysis of the physiological signals of the central and autonomic nerve systems whether the intended emotions were appropriately achieved, and whether these emotion changes could be distinguished from the analysis of physiological signals. Each of the four imaginations was implemented on 32 subjects for 30 seconds, while that Electroencephalogram (EEG), Eelectrocardiogram (RSP) were measured, and a subjective evaluation was implemented following the completion of the measurement. The analysis of the subjective evaluation revealed that the subjects underwent the four clearly differentiated imaginations, and the pleasantness level was classified into four imagination stages, pleasantness>relaxation>arousal=comfort>unpleasantness, and arousal level was classified into four imagination stages in the order of arousal>unpleasantness${\approx}$pleasantness>comfort>relaxation. The analysis of the EEG revealed that three stages of pleasantness level, pleasantness>relaxation=arousal=comfort>unpleasantness were classified from the values of ${\alpha}/{\alpha}+{\beta}\;and\;{\beta}/{\alpha}+{\beta}$, and about tour distinguishable stages of arousal level were obtained from the autonomic nervous system responses following the order of arousal>unpleasantness${\approx}$pleasantness> comfort> relaxation. It was found that intended emotion could be induced from the imagination, and these induced emotion changes could be differentiated using the physiological signals of the EEG and autonomic nervous system.

  • The purpose of this study is to find customer satisfaction at take-out coffee shops by examining their choice attributes, and to find the operational suggestion of the shops by identifying relations between customer satisfaction and choice factors and by finding significant factors, in order to offer subsequential developments for take-out coffee shops. When it comes to choosing a take-out coffee shop, women are found to consider pleasantness, kindness, and warranty more than men do. By age, those in the thirties are found to think much of typicalness, pleasantness, and trust than people in any age do, while those under the twenties kindness. By job, it is found that office workers think typicalness, pleasantness to be important, while students trust The more customers are satisfied at trust and kindness, the more customers are willing to use the shop again. Thus, to make the better service of take-out coffee shops, it requires drastic, continuous training for employees, introduction of specific marketings, management of corporate brand images, manpower administration that will maximize profits with small members, continuous menu development, study of taste, stage preparation and standardized service quality techniques and know-how specific to a coffee shop that will lead customers to revisit the shop.

  • In order to investigate the relationship between fabric sound parameters and subjective sensation, each sound from 60 fabrics was recorded and analyzed by Fast Fourier transform. Level pressure of total sound (LPT), three coefficients (ARC, ARF, ARE) of auto regressive models, loudness (Z), and sharpness (Z) by Zwickers model were estimated as sound parameters. For subjective evaluation, seven sensation (softness, loudness, sharpness, clearness, roughness, highness, and pleasantness) was rated by both semantic differential scale (SDS) and free modulus magnitude estimation (FMME). As the results, the ARC values were positively proportional to both LPT and loudness (Z) values. In both of SDS and FMME, softness, clearness, and pleasantness were negatively correlated with loudness, sharpness, roughness, and highness. In regression models, softness and clearness by FMME were negatively affected by LPT뭉 ARC, while loudness, sharpness, roughness, and highness were positively expected. Regression models for pleasantness showed low values for R2.

  • Different masking materials were evaluated for their ability to ameliorate odor of model poultry manure solution by assessing their effects on sensory pleasantness and odor intensity. Results indicated extracts from Eastern red cedar leaves, Loblolly pine needles', and commercial masking agents such as pine extract and odor neutralizer were effective (p<0.05) for masking odor of model poultry manure solution by increasing (p<0.05) pleasantness (82 and 86% increases in pleasantness using red cedar and pine needle extracts, respectively) and decreasing (p<0.05) odor intensity (odor intensity reduction by 66 and 76% using red cedar pine needle extract). The most odor-active compound in Loblolly pine needle extract was ${\alpha}$-terpineol (1,573.8 ug/g) which is responsible for aroma of pine trees (piney) and effective for ameliorating agricultural odors.

  • Today, people are becoming more conscious regarding environmental-friendliness, and the society as a whole is becoming more aware of it. With such phenomenon, the purpose of this research is to examine how comfort and pleasantness of indoor environment influences when selecting a place for multi-cultural complex. To demonstrate the stated hypothesis, I have preceded the experiment by selecting the C multi-cultural complex of closed-type structure and T multi-cultural complex of open-type structure. The next step I took, in order to validate the public's awareness of environmental-friendliness, was conducting a survey. I then deducted a conclusion through comparison and analysis of experiment measures with survey result. As a result of the research, the experiment measures of each air, light, heat condition of the T multi-cultural complex of open-type structure had a higher measurement for the comfort and pleasantness than the C multi-cultural complex of closed-type structure. Moreover, after validating the consciousness of the public through the survey, they had a tendency preferring T multi-cultural complex of open-type structure over C multi-cultural complex of closed-type structure in terms of comfort and pleasantness. To summarize, it is proper to conclude that the criteria - comfort and pleasantness of indoor environment - has influenced significantly when it comes to selecting a multi-cultural complex through both the experiment and the survey result.

  • In this research, a theoretical model indicating the influence of fragrance sensibility response on attitude toward and buying intention of scented textile products was tested. On-line survey data was collected from a total of 530 consumers who have used or purchased scented textile products. In results, gender differences were found in the multigroup analysis using Structural Equation Modeling. In the model of females, pleasantness, stimulating, familiarity and congruency of scent affected attitude toward scented textile products while pleasantness was only a factor influencing attitude toward scented textile products in the model of males. In addition, pleasantness was the most important factor for Two genders although males indicated a higher level of buying intention toward scented textile products.

  • This study aims to recommend the proper Color rendering index (CRI), the Correlated Color Temperature (CCT), and illuminance levels of Light-Emitting Diode (LED) lighting based on the analysis of the criteria of the current CRI, the CCT, and illuminance levels in merchandising spaces with LED lighting conditions. It would be a basic material to apply in line with user preference for LED merchandising lighting. To this end, it examines relevant literature review on the experiments designed to test whether lighting characteristics affect brightness perception, color appearance, and pleasantness. Highly saturated colors appear brighter than low saturated colors. Two lighting applications - grocery and clothing shop - were created in elaborating the effect of LED lighting characteristics of CRI on color appearance and the CCT and illuminance on pleasantness. The findings show that the criteria of CIE Ra<80 are appropriate to provide better color appearance of illuminated products in terms of LED lighting that can enhance color saturation, particularly for the red color. Furthermore, 2700 K and less than 500 lux for grocery, 4000 K and more than 500 lux for clothing shop are found to be the proper the CCT and illuminance levels respectively to bring better preference under LED lighting.
