  • The purpose of this study is to investigate the habitat of Luciola unmunsana to understand the status of land snails, which are the larvae prey, and to evaluate the effects of larval feeding preferences and prey size for the restoration of the L. unmunsana habitat as a basis for future restoration projects. The research methods included field surveys of the habitat and laboratory experiments on feeding preferences using three types of land snails (Allopeas clavulinum kyotoense, Euphaedusa fusaniana, Pupinella rufa) observed in the habitat. Field surveys of 13 L. unmunsana habitat sites revealed a total of 24 land snail species. The experimental results regarding the larvae prey were analyzed for statistical significance of feeding preferences using Chi-square tests and independent sample t-tests. Consequently, larvae showed the highest preference for A. c. kyotoense, with statistically significant differences in feeding preferences (p<0.05). Also, statistically significant differences were observed in the size between the land snails that were eaten as prey and those that were not eaten. This research can deepen the understanding of the feeding preferences of L. unmunsana larvae and provide practical guidelines for the effective conservation and restoration strategies of the firefly habitat.

  • Objectives This study examined variations in the perceptions of dioxin risk among social groups defined by geographical living location, environmental education, and occupation. Dioxin risk perceptions were analyzed according to values, risk awareness, knowledge, and behavioral preferences. Methods A quasi-experimental survey was designed and conducted on individuals from seven experimental groups in Jeonju city, South Korea, including: people living near incineration facilities; people living far from incineration facilities; governmental experts; non-governmental organization members; office workers in developmental institutes or banks; students who were enrolled in environmental-related classes; and students who were enrolled in business-related classes. Results The results show variations among groups in values, awareness and behavioral preferences. Particular attention should be given to the result that groups with higher connectedness-to-nature values show higher willingness-to-act (WTA) for risk reduction. Result s can be summarized as follows. First, awareness is associated with one's geographical setting. Second, values and WTA behaviors are related to one's environmental-related education and occupation. Third, values are significantly related to WTA behaviors. Conclusions Different cultures, in terms of values or worldview, among groups influence their perceptions of dioxin risk and choices of risk reduction behaviors. It is important to consider values in communicating complicated long-term risk management involving public participation. Further research should be continuously conducted on the effects of multiple dimensions of values on one's WTA for risk reduction behaviors.

  • The current study investigated the relative effects of viewing motivations on viewing preferences and viewing intentions of television food programs. Data collection was conducted by administering a survey to television food program viewers both on and offline. Viewing motivations were categorized as 'information' 'entertainment', 'pass-time', 'companionship', 'relaxation', and 'social interaction'. 'Information' and 'entertainment' proved to be the most important motivational factors affecting viewing preferences for television food programs. 'Information' and 'social interactions' were the strongest predictors of viewing intentions of television food programs. However, 'pass-time' had a negative influence on both viewing preferences and viewing intentions of television food programs. Furthermore, the results of study verified the moderating effects of food involvement in these relations.

  • 비시장재의 가치를 추정하는 많은 연구들은 비시장재에 대한 선호가 모든 경제주체에 있어서 동질적이라고 가정한다. 그러나 현실적으로 비시장재에 대한 선호가 경제주체마다 다를 수 있기 때문에 경제주체간 선호의 이질성을 가정하는 것이 합리적이며 가치추정의 편의를 감소시키게 될 것이다. 본 연구는 방사성 오염 물질인 라돈 가스 농도의 저감에 대한 선호와 도로교통 및 원자력발전의 안전에 대한 선호가 각각 가계들 사이에 이질적일 것인지, 그리고 가계들의 선호가 동질적임을 가정하는 경우에 비해 모형 및 비시장재 가치 추정에 어떠한 영향을 미치는지 분석하였다. 속성가치선택법(choice experiments)과 중첩로짓(mixed logit) 모형을 이용한 결과, 이질적 선호를 허용하는 것이 이를 배제하는 것보다 설명력 있는 모형을 가져다 주었다. 그리고 라돈 농도 저감 및 도로교통 안전 각각에 대하여 이질적 선호가 가계들 사이에 뚜렷이 존재하는 것으로 나타났다. 그러나 원자력발전 안전에 대한 선호의 이질성은 뚜렷이 존재하지 않았다. 이질적 선호를 배제하는 경우와 비교할 때 이를 허용하는 경우의 지불의사액은 라돈 농도 저감의 경우에 평균 2.44배 증가하였으며, 도로교통 안전의 경우에는 1.74배 증가하였다.

  • The objective of the present study is to investigate healing design attributes for adolescent patients and to identify the relationship among healing design attributes and the meaning of home. This study examined the environmental preferences of American adolescents for hospital rooms to investigate age-appropriate healing design attributes. The health-related quality of life (HRQOL) concept was adapted to this study as a theoretical framework. One hundred six American adolescents participated in the survey. Participant adolescents consisted of two groups by their health status: forty-seven adolescent patients who were waiting for their surgical operations in waiting rooms and fifty-nine healthy high school students while they were at school. Participants aged in range from 14-year to 18-year olds with a mean of 16-year olds. Data collection consisted of two different instruments: Emotional state survey with demographics and environmental preference survey. Environmental values that are important to adolescents were control of privacy, having outside view, and quiet places to go. However, staying in a single-bed room for hospitalization is ranked the lowest score for the participating adolescents. Adolescents who perceived higher stress level preferred to have quiet places to go, to control over privacy and to have outside view significantly. The study resulted that the most important design attribute for American Adolescents was "privacy control", which is the essence of the meaning of home. There are some significant discrepancies in environmental preferences of hospital rooms by different genders and different health status.

  • The present study is following a series of research investigations on design resources coming from collected data referring to users' awareness and preferences. The aim of this research is to test the Healthcare Environmental Color Index as a basis for practitioners in the field of healthcare design. An array of color samples selected from previous research, have been presented to the respondents via an online survey, in order to identify the preferences of the two groups on the relation between environmental color and health. As a result of the first experiment and through the comparison of processed data, the maximum percentage of respondents from each group is validating the relation between environmental color and health. For the second experiment we intend to highlight the patterns of color preferences for each group, and thus to test the color samples healing function. The compared data also showed a higher awareness of Koreans than Romanians on the potential of color applied to healing environment. Last but not least in the third experiment we show the top five color samples preferred by each group. It is significant that the comparison of the results validated once more some of our previous findings related to the healthcare environment, such as: the general preference for the green hue (associated to fatigue relax according to color psychology) and the blue hue (sedation release effect) but also the yellow hue - associated to bright energy. Three out of the top five preferred color samples have been identical to both groups while the other two samples have shown characteristic variations. These results show that similarities are strong and can be used in a glocal design strategy as an accessible tool for any practitioner. Based on the Healthcare Environmental Color Index and users' preferences analysis, a new design culture for healthcare can be established and developed.

  • The purpose of this study was to provide basic data for developing effective forest healing programs for retirees by identifying their characteristics and preferences. A survey was conducted on demographic characteristics, overall perceptions of forest healing, and preferences for forest healing programs, targeting a total of 258 retirees visiting a natural recreation forest and a healing forest. The results of the survey suggested that the awareness of the forest treatment program and the hope of participating in it were both high, but the experience of participating in the program was low. Among the forest healing programs, the order of preference was "Breath in the forest", "Wind bathing and sunbathing", and "Feeling negative ions in the valley". Based on these results, it is expected that the forest healing program for retirees will be used as basic data for development of such programs in the future.

  • Based on the result of extraction of common factors executed in order to elucidate the visual attributes of street scenery by types through the rotation of 23 adjective variables by Varimax, the visual attributes expressed after the construction of the facilities using street scenery were anylized to be 4 factors including factor 1 through factor 4. Theexplanation of the 4 factor groups to explain the entire distribution was 65.3% and these factor groups are the psychological attributes felt when using facilities are constructed by securing the street spaces in downtowns and the factors were named as naturalness(factor 1), locality(factor 2), identity(factor 3) and clarity(factor 4) respectively. Based on the result of one-way layout distribution analysis, the preferences for street scenery by types were found out to show considerable differences at 1 % significance level. Based on the result of multiple regression analysis, all of the factors explaining preferences including factor 1 through factor 4 were significant at 1 % significance level. In case other conditions are constant, if the values of the adjective variables related to locality(factor 2) increase by 1 unit, the preferences which are the values of dependent variables will increase by 0.709. The variable with the largest relative contribution among the 4 factor groups was the locality(factor 2) factor group and on the contrary, it was found that the independent variable with least influences was the clarity(factor 4) factor group.

  • This study is the application of a choice experiment to assess Mekong Delta urban households' preferences and motivations for ecosystem conservation in the U Minh forest. The study applied a choice modeling approach to estimate the economic values of the proposed ecosystem conservation program in the U Minh forest by accessing urban consumer preferences and their willingness to pay for the project. Discrete choice experimental data was collected from 450 residents in the cities of the Vietnamese Mekong Delta. The multinomial logit model was employed to identify consumer's stated preferences for the environmental and sustainability attributes of the conservation project. The results showed that Mekong Delta urban residents paid much attention to the proposed project to protect and develop the U Minh forest. In addition, the results showed that higher education, income, and knowledge of the U Minh forest revealed a higher likelihood of selecting the project, while the older residents would select the status quo more than the younger ones. The study also proved that the effect of participation had a strong impact on the willingness to pay for the project. The findings could be useful for policymakers to take action to raise resident's awareness and willingness to pay for the U Minh forest project.
