This study was intended to devise means to encourage participation for organizations taking part in "resident participation parks.", "Resident participation" has become increasingly recognized as an effective means of park management in Korea. To this end, this study analyzed the current status of social networks for civic organizations participating in park management with respect to their degree of participation, credibility and trust, and exchange of information. Among resident participation parks, "Seoul Forest Park" has been widely recognized as a model example; accordingly this study designated Seoul Forest Park as its primary research focus. Thirty core members of resident participation organizations were selected as test subjects. Members of the resident participation organizations under review came from various backgrounds, including government administrative organizations, citizens' groups, residents' groups, and private businesses. Surveys were used to provide data on credibility and trust between organizations, levels of participation, and exchange of information, as well as statistics on demographic affiliation. Results were examined through UCINET, a program designed to analyze social networks. Survey results indicated that 1) The "Seoul Forest Park Conservancy" and the "Seoul Forest Park Management Office" constituted a hub within their social networks that maintained significantly more relationships than other organizations with regard to levels of credibility and trust, participation, and exchange of information; 2) Social networks for organizations wishing to work together, or desiring active participation in the future tended to center on citizens' organizations in the environmental and arts fields; and 3) Women's associations and meetings of neighborhood("tong") leaders had very little significance as a center in the social networks of local residents groups, and indeed very few connections amongst themselves. The results of this research can be applied in the devising of proposals for encouraging participation in resident participation parks in consideration of the social networks between organizations engaging in park management activities for a diverse array of urban parks and other areas.

Although the recent interest in and favor for natural burial has increased, there are still few who choose it as a funeral. The purpose of the study is to supply necessary information to promote the choice of natural burial. For this a survey of 430 students and residents was conducted in Daejeon. The result of the research is as follows. First, there is a significant difference in use intention of natural burial by age and religion. People under the age of 30 and Catholic believers recorded the highest score in use intention of natural burial. Second, there was a significant difference in information on natural burial by age or religion, in religion and philosophy by age, in physical environment by sex or age, and in conservation by sex or age. In general, the lower the age, the higher the positive perception of natural burial was. While females had a more positive perception of physical environment than males, males had a more positive perception of conservation than females. All sub factors of the perception of natural burial such as information on natural burial, funeral style, religion and philosophy, physical environment and conservation had a significant and positive effect on its use intention. However, ratio skew showed that religion and philosophy had the strongest effect on use intention of natural burial, followed by funeral style, physical environment, conservation, and information on natural burial.

Landscape design pursues a balance among different values in our society, but aesthetic value and ecological value in landscapes must bring complex relationships into harmony. Ecological aesthetics can be defined as a domain of study that manages the relationship between landscape ecology and landscape aesthetics to create aesthetically attractive and ecologically beneficial landscapes. Despite the importance of the research area, there has been limited empirical research addressing ecological aesthetics. This article aspires to connect and expand the conceptual framework to the research methodologies of ecological aesthetics. First, this study suggests a conceptual framework that examines the relationship between landscape and perceptual process in the context of ecological aesthetics. This framework stresses the importance of information and design intervention as moderators in this relationship. From this framework, three key topics in ecological aesthetics arise: (1) correlation between ecological integrity and aesthetic preference, (2) "compromised" design and management intervention principles that enhance aesthetic pleasure and still have biodiversity, and (3) the impact of information intervention in aesthetic experience. The framework indicated three domains affect each other; thus, when one domain is studied, the other two need to be considered. Secondly, several theoretical and empirical studies on ecological aesthetics will be reviewed from a methodological point of view. This will help to consider ecological aesthetics research, which has primarily been limited to theoretical discourse in empirical research.

In this study a landscape evaluation was carried out for the submission of a natural landscape conservation plan with the intention to prevent damage to natural landscapes through incautious exploitation. In the case of Korean landscape evaluation, in fact, only the aesthetic value of the landscape is evaluated as related to development projects but the ecological relevance of the landscape cannot be estimated by evaluating only the aesthetic. For that reason, this study performed a landscape evaluation, including the sensitivity limit of visible scenery and the diversity of ecological scenery. For the intention of landscape evaluation in the designation of an essential conservation area and for devising a plan related to this area, a GIS applied to Ian McHarg's map overlay method was used and both the ecological landscape diversity and the aesthetic value of the landscape was surveyed using this map overlay method. A region can be analyzed in relation to the needs for concentration of management in influence analysis of landscape effect elements.

This study is to find physiological effects of acoustic information on landscape preference. Both the volume and the rate of $\alpha$-waves and $\beta$-waves were used to measure the effects in the study. The result of this study are summarized as follows: The outputting amount of $\alpha$-waves are sorted by different types of visual and acoustic factors. The results show that acoustic factors interacted with visual factors. That is, although visual factors are positive, the volume of $\alpha$-waves depends upon the character of acoustic factors; positive acoustic factors produce more $\alpha$-waves than negative or neutral(soundless) acoustic factors. Also the volume of $\alpha$-waves increase in the case of positive acoustic factors even if there is the same negative visual information. The results show that the volume of $\alpha$-waves increase without connecting with the types of visual factors. The volume of $\beta$-waves are largely reduced when visual stimulus is positive and soundless stimulus is provided. On the other hand, they generally increase when both visual and acoustic stimuli are negative, which fosters extremely unstable, tense and upset stress. The rate of $\alpha$-waves increase according to supplying positive acoustic factors in the opposed visual factors. The rate of wave(shouldn't be $\alpha$-waves\ulcorner) is high if both visual and acoustic factors are positive, so it is the most comfortable and causes no stress. Preference is the lowest if visual and acoustic factors are negative, but a -waves are conspicuously low in positive visual and negative acoustic factors.

The study aims at assessing information on cultural festivals furnished through the internet homepage of a provincial government. The study examines 29 tourist festivals of ˝Cultural Festivals of Korea 2001˝, designated by the Ministry of Culture and Tournism. Based on the inquiring table, framed through the previous study, each festival´s information was surveyed and analyzed, by visiting the homepages of provincial governments. The results of the study show that 1) ˝The information of festival˝ is low in quality. Particularly, ˝the contents of festival˝ needs to be improved and expanded and ˝the festival periods˝ should be brought up to date. These are the important factors in making a decision to participate in the festival and the chief attraction of a homepage, well-planned and detailed information can influence more tourists who are interested in visiting a festival. 2) Seventeen festivals support ˝foreign language˝. But ˝festival information˝ is weak as it provides only an outline of festival and doesn´t even contain the date and contents of festival. Valuable information, like transportations, accommodations and restaurants when tourists visit a tourist spot, and detailed festival contents should be provided. 3) ˝Search˝ and ˝Q and A˝ are function which provide specifics for users. In addition to the homepage of a local government, these functions on the web page of cultural festivals or on an exclusive web page of tourism is required. 4) The homepage of festivals should offer ˝the information of participation˝. The convenience of information searchers should be considered by providing them information such as local prices, transportations, accommodations and restaurants which are necessary to participate in festival.

The main objective of this study is to reveal the basic information for structuring the subsequent information monitoring and early warning system and configuring the sustainable programme management of Donggung and wolji, Gyeongju which was much utilized as historic garden with the physical carrying capacity and the psychological carrying capacity according to on-spot observation and survey. The physical carrying capacity can be calculated with landscape node spatial capacity, road spatial capacity and other spatial capacity and the psychological carrying capacity can be calculated with vision, hearing, touch, action feeling and satisfaction. The number of actual tourists was lower than the carrying capacity in daytime, but it was about twice as great as that in the night. And because the tourists were mainly tour groups, the time of environment damaged was short and fixed. The management improvement program was brought forward centre around the results.

Geoparks are worth preserving in an environmentally and heritage. Monitoring and public attention are essential for the conservation and protection of geoparks. The use of Unmanned Aerial Vehicles and the Structure from Motion algorithm enables effective monitoring of geoparks that are difficult to manage due to their wide range of manpower, and various spatial data derived from SfM can be utilized to improve awareness of geoparks that have been lacking. In order to prove this, firstly, we created the 3D spatial data by using the UAV and the SfM algorithm, which is one of the National geoparks of the Hantan-Imjin River area. Using this 3D data for Virtual Reality and 3D printing. After that, we verified the possibility of promoting the geopark through a simple online survey. Finally, we propose a method to utilize all the generated data from each step to promote and research for geoparks.

This study generated regression models to quantify storage and annual uptake of carbon from five native landscape tree species through a direct harvesting method, and established essential information to estimate carbon reduction effects from urban greenspaces. Tree species for the study included the Chionanthus retusus, Prunus armeniaca, Abies holophylla, Cornus officinalis, and Taxus cuspidata, which are usually planted in cities of middle Korea, but for which no information on carbon reduction is available. Ten tree individuals for each species were sampled reflecting various stem diameter sizes at a given interval. The study measured biomass for each part including the roots of sample trees to compute total carbon storage per tree. The annual carbon uptake per tree was quantified by analyzing the radial growth rates of stem samples at breast height or ground level. Regression models were developed using diameter at breast height (dbh) or ground level (dg) as an independent variable to easily estimate storage and annual uptake of carbon per tree for each species. All the regression models showed high fitness with $r^2$ values of 0.92~0.99. Storage and annual uptake of carbon from a tree with dbh of 10 cm were greatest with C. retusus (20.0 kg and 5.9 kg/yr, respectively), followed by P. armeniaca (17.5 kg and 4.5 kg/yr) and A. holophylla (13.2kg and 1.8 kg/yr) in order. A C. officinalis tree and T. cuspidata tree with dg of 10 cm stored 9.3 and 6.3 kg of carbon and annually sequestered 3.2 and 0.6 kg, respectively. The above-mentioned carbon storage equaled the amount of carbon emitted from gasoline consumption of about 23~35 L for C. retusus, P. armeniaca, and A. holophylla, and 11~16 L for C. officinalis and T. cuspidata. A tree with the diameter size of 10 cm annually offset carbon emissions from gasoline use of about 6~10 L for C. retusus, P. armeniaca, and C. officinalis, and 1~3 L for A. holophylla and T. cuspidata. The study breaks new ground to easily quantify biomass and carbon reduction for the tree species by overcoming difficulties in direct cutting and root digging of urban landscape trees.

This study aimed to evaluate preferences of Bukhansan dulegil using sentiment analysis, a natural language processing technique, to derive preferred and non-preferred factors. Therefore, we collected blog articles written in 2019 and produced sentimental scores by the derivation of positive and negative words in the texts for 21 dulegil courses. Then, content analysis was conducted to determine which factors led visitors to prefer or dislike each course. In blogs written about Bukhansan dulegil, positive words appeared in approximately 73% of the content, and the percentage of positive documents was significantly higher than that of negative documents for each course. Through this, it can be seen that visitors generally had positive sentiments toward Bukhansan dulegil. Nevertheless, according to the sentiment score analysis, all 21 dulegil courses belonged to both the preferred and non-preferred courses. Among courses, visitors preferred less difficult courses, in which they could walk without a burden, and in which various landscape elements (visual, auditory, olfactory, etc.) were harmonious yet distinct. Furthermore, they preferred courses with various landscapes and landscape sequences. Additionally, visitors appreciated the presence of viewpoints, such as observation decks, as a significant factor and preferred courses with excellent accessibility and information provisions, such as information boards. Conversely, the dissatisfaction with the dulegil courses was due to noise caused by adjacent roads, excessive urban areas, and the inequality or difficulty of the course which was primarily attributed to insufficient information on the landscape or section of the course. The results of this study can serve not only serve as a guide in national parks but also in the management of nearby forest green areas to formulate a plan to repair and improve dulegil. Further, the sentiment analysis used in this study is meaningful in that it can continuously monitor actual users' responses towards natural areas. However, since it was evaluated based on a predefined sentiment dictionary, continuous updates are needed. Additionally, since there is a tendency to share positive content rather than negative views due to the nature of social media, it is necessary to compare and review the results of analysis, such as with on-site surveys.
