Vegetation is the basis for biodiversity conservation and sustainable development. In the Environmental Impact Assessment (EIA), which is the most direct and efficient policy measure to prevent degradation of nature, vegetation-related assessment has limitations as it is not based on quantitative and scientific methods. In addition, it focuses on the presence of protected species; hence, it does not take into account the role of vegetation as a habitat on a wide-area scale. As a way to overcome these limitations, this study aims to contribute to the quantification and advancement of future EIA on vegetation. Through the review of previous studies, core areas, connectivity, and vegetation condition were derived as the items to be dealt within the macroscopic aspect of vegetation impact assessment. Each item was spatially constructed using land cover maps and satellite imageries, and time series change analysis was performed. As a result, it was found that vegetation has been continuously deteriorating due to development in all aspects, and in particular, development adversely affects not only the inside of the project site but also the surrounding area. Although this study suggested the direction for improvement of the EIA in the vegetation sector based on data analysis, a more specific methodology needs to be established in order to apply it to the actual EIA process. By actively utilizing various environmental spatial data, the impact of the development on the natural ecosystem can be minimized.

This article was prepared for the purpose of reviewing maintenance plans and strategies for designating the celadon kiln site in Banam-ri, Gochang, a monument designated by the city and province as a historical site. Prior to the discussion, the high academic potential of this site, which is attracting attention as a main point of early celadon main point, was explained, and expectations for the future designation of the monument were reviewed. Next, the current status of preservation and maintenance plans of the celadon kiln site in Banam-ri, Gochang were examined. In particular, the current preservation situation was reviewed through an on-site survey on how the ruins, which have not been designated as a monument, should be maintained for historical designation in the future. Above all, it was argued that it was necessary to conduct excavation and literature surveys to clarify the characteristics of the ruins, investigate the surrounding areas, improve information facilities for visitors, and carry out promotion in connection with them. Finally, the definition of historical sites and the status of historical designation of ceramic kilns, along with the strategies necessary for designation, were presented. In particular, the examples of the existing historical designated celadon kiln site in Dotong-ri, Jinan, and Buncheong Kiln Site in Undae-ri, Goheung were reviewed, and three types of excavation surveys, literature surveys, and academic conferences were presented as the target directions for historical designation. The result of the excavation survey is the basis for suggesting that it has cultural property values with completeness, authenticity, and identity. The literature survey is the basis for supplementing the historical and cultural character of the remains that have not been revealed by excavation. The academic conference explained that it is an opportunity to understand the nature and value of cultural assets, such as the location of cultural assets, the status of relics, and events related to relics.

The assessment of perceived naturalness aims to elucidate the human perception and explain the interaction between natural environments and humans. The perception of ecological assets that exhibit distinct characteristics within a specific region can manifest in various representations. Based on the users' perceptions and interviews regarding ecological assets, this study assessed the perceived naturalness from a cultural services perspective. Specifically, the discussions on Ansan City's ecological assets and revolved around the inherent value of naturalness in dimensions, such as the necessity for conservation and the sustainable development of ecological assets, the perception of ecosystem benefits, the representativeness as a local asset, and usability. Subsequently, the Q method was employed to present 25 representative ecological assets to 25 users. As a result, user groups with different value systems for each question were identified, and hypothetical personas for cultural service enjoyment were distinguished. The most representative persona among the 25 users was identified as AWP (a type that values the conservation of aquatic ecosystems, prefers waterfront landscapes, and enjoys walking). Since perceived naturalness is conceptually similar to the "benefits perceived by users" in evaluating ecosystem services, it can provide more practical evaluation criteria for cultural services.

This study empirically analyzed the determinants of the assessment ratio (hereinafter 'AR') based on a total of 2,129 sales cases of forests in Gwangju, Gyeonggi-do. The main findings of this study through multiple regression analysis are summarized as follows. First, this study shows that regional characteristics have significantly different effects on the AR of forest land prices. Specifically, there was a significant difference in the AR depending on the location of the parcel by sub-region and the ratio of residential area, and the higher the number of development plans in progress, the more likely the officially assessed land price will be formed close to the sale price. Second, this study analyzed that location characteristics such as the proximity of the inner and outer center of the jurisdiction and traffic accessibility had a significant influence on the determination of the AR. Third, this study identified significant differences in AR depending on detailed factors such as planning management areas, production management areas, conservation areas for mountain, conservation areas for nature, and restricted development areas as land use and regulatory characteristics of forest lands. Fourth, this study found that land characteristics are a significant factor influencing the AR as an individual factor in forest land.

As coastal areas have a distinct nature with the interaction of the lands and waters, they attract people to enjoy and experience the natural environments physically and intellectually; this generates cultural ecosystem services. Coastal beaches are one of the most common coastal areas for cultural ecosystem services. The purpose of this study was to 1) estimate the economic values of cultural ecosystem services derived from coastal beaches, and 2) expand the estimated values into other beaches across the country using a benefit transfer method. We divided the values of cultural ecosystem services into five different categories based on an extensive literature review: recreation and tourism, landscape and aesthetic, educational, heritage, and inspirational values. The values of tourism and recreation, landscape and aesthetic, and educational services were estimated using the choice experiments. The attributes of the choice experiments consisted of conservation funds, litter, water quality, seascape, landscape, and biodiversity, and the data were collected through online surveys with visitors of 11 representative beaches in Korea. Heritage and inspiration services were estimated using a market goods method based on their expenditures. These values were transferred to 257 beaches across the country. Study results can be used for policy decisions on various restoration and conservation projects caused by coastal erosion and development and on the need and extent of public investments.

The objective of the present study was to determine gender-related and month-related behavioral differences in captive alpine musk deer. The study was conducted at Xinglongshan Musk Deer Farm (XMDF) of Xinglongshan National Nature Reserve in Gansu Province of western China. The integrated method of focal sampling and all occurrence recording was utilized to quantify the behavioural patterns of 45 captive alpine musk deer (Moschus sifanicus) during non-mating season (from August $1^{st}$ to October $25^{th}$), and the behavioural durations of 12 behavioural patterns such as standing-gazing were recorded. The behavioural modes were compared to explore the potential differences between females and males, and the monthly behavioural modes for males and females were analyzed. Our results showed that the captive female deer in XMDF could compensate the energy lost in pregnancy, parturition and lactation through improving its ingestive efficiency. In order to be more sensitive to the changing environment, females expressed more standing-gazing (SG: $67.38{\pm}12.69\;s$) and moving (MO; $27.41{\pm}5.02\;s$), but less bedding (BE: $42.32{\pm}11.35\;s$) than male deer (SG: $56.43{\pm}9.19\;s$; MO: $19.23{\pm}4.64\;s$; BE: $96.14{\pm}15.71\;s$). Furthermore, females perform more affinitive interaction (AI: $7.89{\pm}4.81\;s$) but less ano-genital sniffing (AS: $0.24{\pm}0.13\;s$) and agonistic behaviour (CI: $0.57{\pm}0.26\;s$) than males (AI: $1.45{\pm}1.09\;s$; AS: $0.45{\pm}0.29\;s$; CI: $1.42{\pm}0.67\;s$). The females expressed ingestion more in October ($132.31{\pm}27.47\;s$) than in August ($28.80{\pm}18.44\;s$) and September ($45.1{\pm}10.84\;s$), and the males performed Ano-genital sniffing (AS: $1.79{\pm}1.14\;s$) and self-directed behaviour (SD: $12.61{\pm}5.03\;s$) significantly more in October than in August (AS: 0 s; SD: $0.62{\pm}0.17\;s$) and September (AS: $0.02{\pm}0.01\;s$; SD: $0.17{\pm}0.15\;s$). Moreover, male musk deer increased the intension of ano-genital sniffing, agonistic behaviour and tail rubbing behaviour, which were related to sexual activities.

This study has been conducted as a basic research for developing efficient ways of managing Korean National Parks by finding differences via the comparison of present management systems of national parks in Korea and Japan. The survey was conducted through telephone interviews and direct interviews with staffs of related organizations as well as related literature study. In result, it is found that Japanese national parks have a numerical standard of minimum area, with less staff than Korea, and larger designated areas are being managed. Management organizations of both countries are divided as main and commission. In Korea, 6 staff in Natural Resources Division under Ministry of Environment are managing main organization, and in Japan, 53 staff of 3 divisions(National Park Division, Natural Environment Management Division, General Affairs Division) are taking charge of it. Moreover, General Affairs Division, dividing whole country into 11 blocks, manages 11 units of natural preservation offices, 12 branch offices, and 67 units of nature preservation management offices. In case of commission, Foundation of Natural Park Beautification & Management in Japan has a headquarter and 20 branch offices with 54 staff who are only doing site management, while in Korea, the National Parks Management Corporation has a headquarter and 25 offices with 748 staff carrying out main office jobs and site management side by side. From the differences in both countries, we could suggest efficient measures for our national park management as follows: \circled1 introduction of numerical value as criteria for national park designation, \circled2 review of use zone, \circled3 division of the national park management office into site office and regional office, with dividing works and re-posting staff, \circled4 enlargement of park management division in Department of Environment, \circled5 National Park authority becomes a national public servant

This study was conducted to evaluate in situ soil flushing and coagulation for naphtalenes-contaminated soil remediation. Mixed-surfactant of 1% POE12 and 1% SDS (1 : 1 by volume basis) was used as a flushing solution. When 5 pore volumes of mixed -surfactant were added to soil column, the flushing efficiencies of 2-methylnaphtalene and 1,5-dimethylnaphtalene with about 1,500 mg/kg(dry soil) were approximately 80% and 60% respectively. In adding 13 pore volumes of mixed-surfactant, the flushing efficiencies of 2-methylnaphtalene and 1,5-dimethylnaphtalene were 90% and 82%. However, considering in situ soil flushing with distilled water, about 42% and 71% were flushed for 2-methylnaphtalene and 1,5-dimethylnaphtalene by surfactant-only. For about 10,000 mg/kg(dry soil) diesel-contaminated soil, 40% and 70% of TPH were flushed-out in 5 pore volumes and 13 pore volumes addition. However, for naphtalenes in diesel TPH, 90% of flushing efficiency was discovered in adding only 5 pore volumes of flushing solution. There was not discovered significant difference among coagulation efficiencies of 6 kinds of polymers, and the coagulation efficiencies were near 50%.

Egg development and early life history of the Korean natural monument fish Hemibarbus mylodon (Pisces: Cyprinidae) were investigated to provide basic data on biological characteristics and ecological recovery. Adult fish were collected from nature and transferred to the laboratory. For the first time, artificial maturation of females and males succeeded after 15 months of indoor culture. Mature eggs and sperm were obtained using Ovaprim injections (0.5 mL/kg) and then the eggs were fertilized using the dry method in the laboratory. The mature eggs were adhesive, turbid, and greyish; they averaged $2.21{\pm}0.06mm$ (n=30) in diameter. The embryos began to hatch about 78 h after fertilization at a water temperature $20{\pm}1^{\circ}C$, and the newly-hatched larvae were $6.6{\pm}0.75mm$ in total length (TL). At 14 days after hatching, the post-larval individuals were $13.5{\pm}0.23mm$ (TL), and their yolk sacs were completely absorbed. Twenty one days after hatching, they entered the juvenile stage and reached $13.5{\pm}0.23mm$ (TL). At 100 days after hatching, their band patterns, external form, and a pair of barbels were similar to those of adults, and they averaged $33.0{\pm}4.25mm$ (TL). The breeding technology and characteristics of early life history obtained in this study will be very helpful for conservation of H. mylodon in nature.

Korea's natural parks are managed by dividing them into four use districts: nature preservation district, natural environment district, cultural heritage district, and park village district within the park under the goal of 'conservation and sustainable use of natural parks'. However, the use districts divided in this way are designated by reflecting the results derived from the simple drawing overlapping method, and there is a limit in that objective and scientific evidence for this is insufficient. In addition, in Taeanhaean National Park, the case of this study, only a very small area of less than 1% of the nature preservation district is designated, and the natural environment district that serves as a buffer space is designated on an excessively wide scale, making it difficult to efficiently manage the national park. Therefore, the use district is not fulfilling its role. In this study, the purpose of this study was to present a method for analyzing the spatial characteristics of natural parks using environmental indicators and unsupervised learning analysis methods to set the use districts of natural parks. In this study, evaluation indicators that can evaluate the natural and human environments were derived, and the distribution patterns for each indicator were analyzed. Afterwards, by applying Self-Organizing Map (SOM) analysis, one of the unsupervised learning analysis methods, districts with similar characteristics were derived in Taeanhaean National Park, and the characteristics of each district were analyzed. As a result of the study, 7 districts with different characteristics were derived in Taeanhaean National Park, and by examining the contribution of each indicator together, it was possible to reveal that each district had different representative characteristics even though it was an adjacent area. This study evaluated natural parks by comprehensively considering the indicators of the natural and human environments. In addition, the SOM method used in the study is meaningful in that it can provide scientific and objective grounds for the existing zoning and apply it to the management plan.
