This study was performed to investigate the awareness of an ecological city and its related variables and the willingness to move to an ecological city and its related variables. Data were collected through a questionnaire survey given to 491 residents in Mokpo, Kwangju and Muan in Chollanam Province. Awareness of the ecotogical city was medium level, half of the respondents were not aware of the ecological city. Multiple regression analysis was conducted to estimate the effects of the variables on the awareness of the ecological city. The most significant variable was environmental knowledge. Next, experience in environmental education and homeownership effected on the awareness of the ecological city. Those who knew about environmental pollution and environmental disruption had a self-reported higher degree of awareness of the ecological city. Those who had experience in environmental education as well as those who lived in their own house were more aware of the ecological city. Other variables were not statistically significant. Half of the respondents were willing to move to the ecological city. Seven variables were related with willingness to move to the ecological city. Those who knew about the environmental pollution and environmental disruption preferred to move to the ecological city. Those who lived in multi-housing had more of a willingness to move to the ecological city. People with a higher education as well as the younger group preferred to move to the ecological city. Those who were more aware of the ecological city and had more ecological-oriented values had more willingness to move to the ecological city. Salaried men and professionals were more willing to move to the ecological city than non-employed people. Among those variables environmental knowledge was the only influential variables on willingness to move to the city.

This study was planned to test the educational effects of self-guiding environmental interpretation panel. For purpose of the study, self-guiding interpretation panel was set up along the trail of green shower area of Kwang-Reung Arboretum in 1995,and the environmental behavior related variables such as attitude, locus of control, personal responsibility, general knowledge, and intention to act were closen based on Hines and his colleagues' Responsible Environmental Behavior model(1987). The pre-test/post-test non-random control group design was introduced fo test the effects of panel. ANCOVA was used to test the differences between experimental and control group because of the need to consider the effects of other variable such as socio-economic variables on the changes of environmental behavior related variables. Among 5 environmental behavior related variables, the changes of attitude and knowledge were significantly different between experimental group and control group, and the experimental group's direction of change was more favorable for environment. It is concluded that the educational effects of self-guiding interpretation panel were partially accepted. Several recommendations and restrictions of the study are presented.

Climate vulnerability index is usually defined as a function of the climate exposure, sensitivity, and adaptive capacity, which requires adequate selection of proxy variables of each variable. We selected and used 9 proxy variables related to climate exposure in the literature, and diagnosed the adequacy of them for application in Korean peninsula. The selected proxy variables are: four variables from temperature, three from precipitation, one from wind speed, and one from relative humidity. We collected climate data over both previous year (1981~2010) and future climate scenario (A1B scenario of IPCC SERES) for 2020, 2050, and 2100. We introduced the spatial and temporal diagnostic statistical parameters, and evaluated both spatial and time variabilities in the relative scale. Of 9 proxy variables, effective humidity indicated the most sensitive to climate change temporally with the biggest spatial variability, implying a good proxy variable in diagnostics of climate change vulnerability in Korea. The second most sensitive variable is the frequency of strong wind speed with a decreasing trend, suggesting that it should be used carefully or may not be of broad utility as a proxy variable in Korea. The A1B scenario of future climate in 2020, 2050 and 2100 matches well with the extension of linear trend of observed variables during 1981~2010, indicating that, except for strong wind speed, the selected proxy variables can be effectively used in calculating the vulnerability index for both past and future climate over Korea. Other local variabilities for the past and future climate in association with climate exposure variables are also discussed here.

The purpose of the study is to inquire how the family environmental variables are to influence on the behavior, time of laundering and laundering facilities in the urban households. Independent variables are limited to the number of family members, the are of the youngest child, the age of the home maker, and her educational level, family income , and the type of housing in which the family lives. The total of 222 samples were thus selected. The data was analyzed on the basis of statistical method such as percentage, mean ,standard deviation, chi-square, and F-test. The major findings are as follows; 1) Hypothesis 1 is rejected, because the behavior of laundering management is not influenced by six family environmental variables. 2) The facilities for laundering management are affected by the home maker's age(p<.05), her educational level(p<.001), family income (p<.001), the housing of the family (p<.01) among six family environmental variables ; there fore, Hypothesis 2 is partially proved; 3) the time for laundering management is affected by the number of family members(p<.01), the age of the youngest child(p<.05), the home maker's educational level(p<.001) among six family environmental variables; therefore, Hypothesis 3 is partially proved.

Purpose: The purpose of this study is the time series analysis for predicting the yield of crops applicable to each farm using environmental variables measured by smart farms cultivating tomato. In addition, it is intended to confirm the influence of environmental variables using a deep learning model that can be explained to some extent. Methods: A time series analysis was performed to predict production using environmental variables measured at 75 smart farms cultivating tomato in two periods. An LSTM-based encoder-decoder model was used for cases of several farms with similar length. In particular, Dual Attention Mechanism was applied to use environmental variables as exogenous variables and to confirm their influence. Results: As a result of the analysis, Dual Attention LSTM with a window size of 12 weeks showed the best predictive power. It was verified that the environmental variables has a similar effect on prediction through wieghtss extracted from the prediction model, and it was also verified that the previous time point has a greater effect than the time point close to the prediction point. Conclusion: It is expected that it will be possible to attempt various crops as a model that can be explained by supplementing the shortcomings of general deep learning model.

The honeybee serves for most entomophilous flowers. They are a core species for maintaining the ecological system. Though the urban ecological system needs bees' mediation of pollination as well, we have little understanding on how the honeybee reacts to the physical environments of an urban city. This study is a basic research to enhance the potential environment for pollination in an urban area and aims to review the urban environmental variables which are highly linked to the pollination mediations by the honeybee. The study composed a Maxent model by adopting nine urban environmental variables and the locations of the Apis mellifera's appearances around 52 spots in Seoul. The variables reflect the ecology of the Apis mellifera. Of the urban environmental variables used for the model composition, six variables were found as not having meaningful correlations with the Apis mellifera's appearances and finally, building coverage, actual vegetation and land cover were selected as the appearance variables of the Apis mellifera. The AUC, the reliability indicator of the final model was 0.791 (sd=0.077). And the importance data of the variables used for the model were 55.6%, 27.9%, and 16.5% for building coverage, actual vegetation and land cover, respectively. The result of the study showed that the building coverage has the highest correlation with the appearance of the honeybee. And, as per the actual vegetation, the artificially tree planted area as well as the cultivated field and meadow in an urban area were functioning as the most important environmental conditions for the honeybee to be inhabitable. The study is expected to be utilized as the base material for the urban planning and park green area planning to enhance the potential environment for pollination in an urban area.
