Purpose - This is longitudinal research which aims to investigate the meaning of greenness to consumers' behavior. Consumers adopt green marketing as a new factor in product buying and consumption and more and more consumers prefer green product and services. Consumers' green buying behavior can be different from other purchasing experiences. There would be changes in the meaning of green as time passed and it can be different from countries to other countries. This study examines focus group studies with several groups. There is a ten-year gap between 2010 focus group and 2019 focus group interviews. With this ten-year gap, we can find the change of greenness to consumers. Research design, data, and methodology - The data were collected from Turkish, Korean, Kazakhstan people. This is a cross-sectional study and focus group interview was designed. We can gain information relevant to the research problem with using focus group study and get some insights into basic needs and attitudes of green marketing. The subjects for green purchase interviewee were confined to under 40 years old's shoppers regardless of gender. The first study was investigated with several groups in 2010 and the second interview were conducted in 2019. Results - Results show that the meaning of greenness for consumer has changed over time in accordance with the growing accordance of environmental sustainability. Basically, green marketing still means valuable, natural, recycle-able, good for health, clean, smart behavior, essential benefit. The concept of greenness significantly evolved since it was investigated in 2010. It moves away from focusing on specific environmental issues to considering global sustainability issues. Especially we found that greenness can be related with globalization, higher education, social status at the 2019 interview. Conclusions - This paper attempted to confirm the green marketing is essential and expands its meaning to various aspect. Usually, we can think green marketing is everywhere, therefore, people don't care about green issues in real. But consumers are adopting green marketing more and more, it can be a means to attract potential consumers. Therefore, companies should provide enough greenness information for people and they might apply greenness communication to attract potential customers.

This study was conducted based on the 115 development projects of residential areas during 2001-2006 to investigate the current status of park green areas. Prior Environmental Review System (PERS) was categorized into regions, scales, and time of the projects, and regression model was used for a statistical analysis. The ratios of greenness of Seoul and Gyunggi province were greater than those of other regions whereas the ratios of greeness of Cheonnam, Chungbuk, and Jeonbuk provinces showed smaller percentage of green areas. Secondly as the scales of development get bigger areas of greenness become larger indicating a large scale residential development projects are favorable for securing green areas. Thirdly the correlation between planned area and green areas, and that between planned population and the ratio of greenness are relatively low (P>0.05). This implies green areas are not a good indicator but a concrete guideline for green areas. Fourthly the ratio of greenness of small scale project is not reached to 10% so that it is recommended to secure over one million $m^2$ areas for development project.

The purpose of this research is to suggest the planting methods and the reasonable target levels of IGS for promoting green streetscape in Seoul. Using the three dimensional computer simulations, various greening methods were applied to evaluate effectiveness of promoting green streetscape. The results of this study suggest that promoting tree planting on car lane is more effective than on pedestrian side walks. In wide streets, the height of tree has positive effects on promoting green streetscape. In both car lane and pedestrian side walks, the greening effects of tree planting both in zig-zag pattern and in parallel pattern were similarly most high. The width of strip in side strip planting has positive effect on promoting green streetscape. Promoting stratified planting is very effective. Promoting greening wall on pedestrian side walks is more effective than on car lane. Combined the results of IGS survey with the public officials and complex simulations, suggest that the optimal levels of IGS is ranging from 12.0% in alleys to 54.0% in car lanes among arterial roads.

We discuss the Normalized Difference Vegetation Index (NDVI) of the forest canopy and floor separately based on airborne spectral reflectance measurements and simultaneous airborne land surface images acquired around Yakutsk, Siberia in 2000. The aerial land surface images were visually classified into four forest types: no-green canopy and snow floor (Type-1), green canopy and snow floor (Type-2), no-green canopy and no-snow floor (Type-3), and green canopy and no-snow floor (Type-4). The mean NDVI was calculated for these four types. Although Type-2 had green canopy, the NDVI was rather small (0.17) because of high reflection from the snow cover on the floor. Type-3, which had no green canopy, indicated considerably large NDVI (0.45) due to the greenness of the floor. Type-4 had the largest NDVI (0.75) because of the greenness of both the canopy and floor. These results reveal that the NDVI depends considerably on forest floor greenness and snow cover in addition to canopy greenness.

The purpose of this research is to analysis the application of the ISG(Index of Streetscape Greenness) in EIA through case study of Seoul. ISG is a new index which directly expresses human's perceptions of plants in a street and is defined as the area ratio of which leaves of plants occupy an eye-level view of a person standing on the center line of a street. In this research the 42 cases of 3 step reports such as plans, drafts, and final reports which had been passed through the EIA procedure of Seoul were analyzed. The results are as follows: In the drafts frequent mistakes or errors such as unsuitable picture composition, unsuitable sample points, inconsistency of the simulation result with the planting plan, and insufficient numbers of analysis were found, but almost of them were corrected in the final reports. In the most of final reports, the 30% of minimum requirement was satisfied. At all cases the changes of the ISG values were clearly positive. Finally the average current ISG was 19.6%, meanwhile the average proposed ISG was 35.4%. It was verified that the ISG is very practical index to promote green streetscape, but in order to guarantee an achievement a thorough investigation of reports are needed.

This study is to examine the effect of improving the forest therapy program for adolescents using forest healing resources (focused on improving index of greenness for adolescents). The participants were 30 students from in the control group that participated in the 2018 program, and 51 students in experimental group that participated in the improved program in 2019. The questionnaire, developed by Korea Forest Welfare Institute, was comprised of items on general matters, index of greenness, restorative environment, positive emotion, negative emotion, facial expression and psychological assessment. The control group had 30 and the experimental group had 49 valid copies of the questionnaires. As a result of the paired sample t-test for each group, the control group showed a significant increase in all categories except restorative environment. In the experimental group, all categories significantly improved to a higher level (p <.01). An independent sample t-test (one-tailed test) was performed to test the effect of the forest therapy program with improved index of greenness. As a result, the index of greenness increased by 0.73 points(t=2.555, p <.01) and restorative environment by 1.01 points (t=2.567, p <.01), showing statistical significance. Negative emotion increased by 0.04 points (t=0.183, p >.05), which was not significant. On the other hand, positive emotion decreased by 0.42 points (t=-1.918, p <.05), facial expression by 0.57 points (t=-1.775, p <.05), and psychological assessment by 0.29 points (t=-0.981, p >.05), showing significance in positive emotion and facial expression. However, all the decreased items showed significant improvements between the pretest and posttest scores of the experimental group.
