This study is a basic research to suggest user-centered healthcare environmental color, which aims to analyze tendency of color consciousness and preference depending on the user characteristics (generation, gender, residential area, and environment). For this purpose, this study constructed an analysis tool through the literature review with regard to environmental color of healthcare facility and influential factors of color preference. Besides, an online survey regarding general usage and satisfaction, health related color consciousness, and color preference tendency of healthcare facility was conducted targeting from 20s to 60s, total 1,500 persons. The results of this study are as follows: (1) The usage and satisfaction of healthcare facilities were higher for older generation and accessible urban area. (2) The respondents were aware that color and health are related, recognizing 'green' as healthy and stress relieving color. Besides, 'natural' and 'clear' was the highest in health related color image. 'Light' which relates to vitality was high as well for older generation. (3) In the color preference tendency survey, hue PB was generally the most highly preferred, in details, younger generation preferred B and R while older generation preferred G. The survey also showed high value and chroma were preferred, while female and younger generation preferred high value of 9.0 and low chroma close to achromatic color, which presented older generation preferred vivid color.

THe purpose of this study is to suggest the major determinants of visual preference in the outdoor spaces of urban office buildings. For this, the spatial image was analyzed by the factor analysis algorithm. The level of visual preferences was measured by a slide simulation test, and these data were analyzed by the multiple regressioni. The result of this study can be summarized as follows; Factors covering the spatial image were found to be 'mystery','changeability','coherence' and 'legibility'. T.V. was obtained as 58.4%. Outdoor spaces of urban office buildings were classified into four groups by the multi dimensional scaling method. As for the analysis of imageability in each spatial type, the factor scores of measuring high values were different for all types. Type II, IV obtained higher rank of visual preference and type III, I obtained lower. For all types, the factors of visual preference were found to be 'mystery','changeability','coherence' and 'legibility'. The visual preference determinants of urban setting focused on outdoor spaces of urban office buildings may be the major factors which must be considered in planning and designing as the functional basis for the quantitative analysis.

This study investigated the effects of a healthy image on the preference and intake frequency of meat and animal products. The study looked into beef, pork, chicken, sausage, mackerel, cutlass fish, croaker, tuna, squid, shrimp, clams, fish cakes, eggs, milk, yogurt, ice cream, and cheese. A total of 359 usable surveys given to elementary school students, college students, and adults were collected using a convenient sampling method. While milk had the healthiest image, sausage had the least healthy image. The respondents preferred yogurt the most and sausage the least. The intake frequency of eggs was the highest and clams the lowest. The healthy image, preference, and intake frequency for all studied foods showed significant differences across both gender and age. The relationship between healthy image and preference was significant for all foods, and a healthy image always had a positive influence on preference. The relationship of healthy image and intake frequency was significant in 14 foods except for mackerel, cutlass fish, and tuna. Also a healthy image created a positive effect on the intake frequency of 14 foods.

Although many studies have focused on dietary habits and behaviors among children, few have looked at individual dietary behaviors and food preferences and their relationships with personality traits. This study examined the relationships between children's dietary behaviors, food preferences and personality traits using a random sample of 236 sixth graders in Chuncheon. Results showed a high prevalence of undesirable dietary behaviors among children: 42.8% of the children had skipped breakfast at least twice a week, 53% had overeaten, 45.8% had eaten irregularly, and 66.5% had eaten an unbalanced meal. These undesirable dietary behaviors were negatively associated with such personality traits as sociability, responsibility, emotional stability, activity, and superiority. When asked about food preference, fruits were most popular while vegetables were least desirable. Total food preference scores were positively correlated with emotional stability (r=.204), activeness (r=.247), sociability (r=.156), responsibility (r=.249), and superiority (r=.133). Preference for meats had negative correlations with responsibility (r=-.133), sociability (r=-.146), and superiority (r=-.132), while preference for vegetables was positively correlated with these personality traits (r=.292, .244, and .230, respectively). In conclusion, the more desirable dietary behaviors and the higher total food preference scores, the more positive the child's personality traits. In addition, preference for vegetables was associated with positive personality traits. The findings suggest the need for continuous attention and guidance on desirable dietary habits for school children both at home and at school.

This study was to investigate the preference test of among 10’s and 20’s in New York, Atlanta, Chicago and Sanfrancisco in USA. Preference of packaging, design, printing, flavor, texture and overall preference surveyed. About thirty percent of the respondents showed high score in packaging among the items. The design and color of Yukwa was 22.0％ and 24.1％ in “excellent”. American did not prefer the texture due to stickiness of Yukwa. However, 92.7％ of the respondents showed high score in overall acceptability of Yukwa. On the basis of this result Yukwa would he developed for residential people’s preference. It is possible to export successfully the Korean traditional snack, Yukwa.

Purpose: The influence of age on time preference is not identified in the usual cross-sectional analysis. This study aims to test whether age affects time preference after controlling for the effects of individual heterogeneity including cohort effects. Research design, data and methodology: Drawing on a nationally representative panel dataset of Indonesians, we estimate the effects of age on time preference after controlling for unobserved individual heterogeneity as well as potential cohort effects. We measure time preference exploiting information on two sets of multiple price lists: one for a one-year delay, and the other for a five-year delay. Results: When we controlled for time-invariant individual characteristics, including birth cohort effects in a fixed effects model, the older men and women were more patient in a linear fashion, particularly when the delay was longer. To highlight the importance of controlling for individual fixed effects, we repeated the specification without controlling for individual fixed effects in OLS or censored maximum likelihood regression; we found no relation between age and impatience in men or women and for a one or five-year delay. Conclusions: The older men and women are more patient, and time preferences are correlated with unobserved individual heterogeneity.

Nowadays, the concept of outdoor campus is different from the past. U-Campus with a well-developed high-speed computer network is no longer a constraint on the campus interior and exterior spaces. From this point of view, today's large-scale university outdoor spaces need to be changed from a simple green space. The university campus outdoor spaces need to be changed into a new concept space. This study analyzed the changes in academic activities and preferences of college students who are users of university campus outdoor spaces and it is aimed at space planning that reflects the preference. The university campus should be remodified through changes in students' behaviors. Participants in this study were four different departments students (Social science, Physical education, Natural science and Engineering). The preference results of 17 items were analyzed. As a result of this preference analysis, we found that there is a difference in preference among students belonging to four different departments students. In conclusion, this study will propose that the preferences of each college should be considered in planning the outdoor rest spaces of university campus.

Various room acoustic parameters and their optimal values were proposed and verified as proper interpretations to the listeners' preference of concert hall sounds. However the listening environment has been changed since they were developed, and the listeners' preference may not be the same among countries of different cultural backgrounds. Actual listeners' preference should be applied to the design of a new concert hall. A survey on the listening preference was carried out for 22 music experts. A room acoustical design process was proposed which made the acoustical environment of a concert hall as close to the listeners' preferences.

The sea urchin, Mesocentrotus nudus, is widely distributed in North West Pacific regions. It has a substantial impact on macroalgal communities as a generalist herbivore. This study examined various aspects of its feeding ecology, including algal preference, foraging behaviors, and possible effects of past feeding history on its algal preference. We used six common algal species (Ulva australis, Undaria pinnatifida, Sargassum confusum, Dictyopteris divaricata, Grateloupia elliptica, and Grateloupia angusta) from the east coast of Korea as food choice in a series of indoor aquarium experiments. The first choice of starved M. nudus was exclusively U. pinnatifida, followed by G. elliptica and S. confusum. Unlike large urchins, small urchins equally preferred U. pinnatifida and G. elliptica. On the other hand, Undaria-fed urchins preferred to feed only G. elliptica, although its preference slightly differed over time. We then grouped sea urchins into three categories (starved, Undaria-fed, mixed species-fed) to observe 12-days feeding preference as well as early foraging movements. Foraging behaviors of the three groups were distinctively different, although they could not completely reflect the actual consumption. For example, U. australis was highly attractive, but rarely eaten. Undaria-fed urchins seemed to stay with only S. confusum and U. australis. This study demonstrates that M. nudus shows high flexibility in food preference depending on past feeding history and body size. Its foraging behaviors are also affected by past feeding conditions, exhibiting active chemoreceptive movements.

Purpose Since COVID-19, the demand for online class platforms has increased. However, those platforms have not been clearly defined, and related research is also limited. In the context of the knowledge marketplace (KMs), this study examined the effects of class information and trust in creators on class preferences from the perspective of consumption value theory. Design/methodology/approach By establishing a web crawler through Python, this study collected 1,174 class data in Korea's leading knowledge marketplace, Class 101, focusing on diverse class-related information and the number of Instagram followers for individual class creators. Based on class information, this research analyzed the effects of consumers' utilitarian value, social value, and hedonic value on class preference. In addition, this study examined whether consumers' trust in creators moderates the relationship between class information and class preference. Findings According to analysis results, it was found that the higher the consumers' consumption value for each class on KMs, the more positive their preference for the class. Also, it was confirmed that consumers' trust in creators moderates the relationship between class information and class preference.
