This study was to identify the differences on cognitions for conservation on the Rice Terraces landscape between local residents and visitors. For this purpose, this study drew problems and implications through consideration about advanced studies and then carried out a survey of local residents and visitors. The results of this study analyzed five factors that are the components of cognition about the Rice Terraces landscape: production, policy, landscape, management, and revitalization. The Cognition of Rice Terraces landscape indicated that local residents had more positive evaluation than visitors did. In addition, there were indicated differences in most items. Particularly, the local residents had more positive evaluation than visitors did in production(rice paddy of fallow ground, form of traditional rice paddy, weeds), landscape(cultural value, footpath of rice field and stonewall), and revitalization(common program for local residents and visitors, village revitalization from festival and event). Visitors had a more positive evaluation than local residents in terms of policy(designation of a place of scenic beauty, direct payment) and management(cooperation of local residents and visitors). In consideration of these results, it needs to draw up measures that are able to build up a common cognition to overcome differences between local residents and visitors. It is based on the knowledge and opinions that visitors and local residents had concerning history, traditions, cultures and production.

This study was conducted to investigate and analyze the designation status of the Local Wildlife Conservation Ordinance for the conservation and management of wild fauna and flora, and to elucidate the problems and improvement directions. We compared and analyzed the provisions of the wildlife conservation ordinance of 17 regional local governments. After that,the designation status of Wildlife Protected by City/Do was investigated and the appropriateness was confirmed based on guidelines and laws. The ordinances related to wildlife were enacted in all municipalities, and provisions such as selection criteria, protection measures, and act limitations were commonly reflected. The provisions were varied depending on the characteristics of each local government, including details of flag species, the addition of species in the restoration promotion plan as criteria for selection and provision of protection and restoration of habitats. Since 2006, when the wildlife protected by City/Do designation and protection guidelines have been established, the protected wildlife have increased sharply, and there has been newly designated regional local government within the past one or two years. However, in some local government, protected wildlife has been designated for more than 10 years, and there are many that do not meet the selection criteria. Therefore, more scientific and objective selection criteria and methods should be constructed for the selection of species suitable for the purpose of the Wildlife protected by City/Do.

The purpose of this study was to identify the ecological characteristics of Namhan Mountain Fortress Walls vascular plants through investigation and analysis of Namhan Mountain Fortress Walls and to provide basic data when establishing a plan for conservation and management of Namhansanseong Fortress Wall vascular plants. The result of this survey revealed 249 taxa composed of 77 families, 169 genera, 222 species, 5 subspecies, 19 varieties and 3 forms. In terms of life form of Namhan Mountain Fortress Walls, the appearance rate of Hemicryptophytes(H) was high. Rare plants was 1 taxa and Korea endemic plants was 5 taxa. The total number of floristic regional indicator plants was 15 taxa, gradeI 9 taxa, gradeII 2 taxa, gradeIII 3 taxa, gradeIV 1 taxa. Among them, Polygala tatarinowii Regel is considered to the most important(gradeIV), and it is first description because in Gyeonggi-do, as no additional forms have been confirmed other than this site. Plants identified as rock vegetation were found in 21 taxa. Invasive alien plants were identified 20 taxa. Plants distributed on the walls of Namhan Mountain Fortress, such as Aconitum longecassidatum Nakai, Clematis heracleifolia DC. var. tubulosa (Turcz.) Kuntze, Hylotelephium spectabile (Boreau) H.Ohba and Polygala tatarinowii Regel etc, are feared to decrease the number of species and individuals due to the loss of walls, the spread of invasive alien plant and human interference, so conservation and management measures are needed.

Traditionally, like many people in mountain region of the Himalaya, the Lwang communities depend on mix of subsistence agriculture, animal husbandry, and seasonal migrant labor for their livelihoods. These traditional systems are characterized by low productivity, diverse use of available natural resources (largely for home consumption), limited markets, and some aversion for innovation. The potential to generate wealth through commerce has largely been untapped by these mountain residents and thus is undervalued in local and national economies. Introduction of organic tea farming is a part of Lwang community's several initiatives to break the vicious poverty cycle Annapurna Conservation Area Project (ACAP) played facilitating roles in all their efforts since beginning. In five years, the tea plantation emerged as a new means for secured a livelihood. This study aims to analyze the current practices in tea farming both in terms of farm management and soil nutrient status(technical) and the prosperity of the tea farmers (social). The technical aspect covers the soil and tea leaf analysis of various nutrients contents in the soil and tea leaf. Originally, the technical aspect of the study was not planned but later during the consultation with the advisor it was taken into consideration which added value to the research study. The sample were collected from different locations and analyzed on the field itself. The other part of the study i.e. the social aspect was done through questionnaire survey and focus group discussion. the tea farming provided them not only a new opportunity but also earned an identity in the region. This initiative was undertaken as a piloting measure. Now that the tea is in production with processing unit established locally, more serious consideration has to be given for better yield and economic prosperity. This research finding will help the community to analyze their efforts and make correction measures in tea garden management and application of fertilizer. It is also expected to fill up the gaps of knowledge and information required to reduce economic stresses and enhance capacity of farmers to make the tea farming a sustainable and beneficial business. The findings are expected to Sustainability of organic tea farming has direct impacts on biodiversity conservation compared to the other traditional farming practices that are more resource intensive. The study will also contribute to identify key action points required for reducing poverty while conserving environment and enhancing livelihoods

The Eurasian otter (Lutra lutra) is an apex predator of the riparian ecosystem. It is a keystone and an indicator species; consequently, its presence suggests a sustainable water environment. Otter is a keystone species as a predator at the top of the food web in the aquatic environment and an indicator species representing the health of the aquatic environment. Although Eurasian otters disappeared from the Han River urban water system because of anthropogenic activities like habitat destruction, poaching, and environmental pollution in the 1980s, the species were sighted in the Cheonggye Stream, Jungrang Stream, and Seongnae Stream, which are urban sections of the Han River, in 2016 and 2021. Therefore, it is pertinent to assess the habitat potential in the area for conservation and management measures to ensure its permanent presence. However, existing studies on otter habitats focused on natural rivers and reservoirs, and there is a limit to applying them to habitats artificially confined habitats in narrow spaces such as tributaries in urban areas of the Han River. This study selected the Cheonggye Stream, an artificially restored urban stream, to evaluate its potential as a habitat for Eurasian otters in urban water environments using the habitat suitability index (HSI). The HSI was calculated with selected environment attributes, such as the cover, food, and threat, that best describe the L. lutra habitat. According to the results, the confluence area of Seongbuk Stream and Cheonggye Stream and the confluence area of Cheonggye Stream and Jungnang Stream were suitable otter habitats, requiring appropriate conservation efforts. The HSI model suggests a valuable method to assess the habitat quality of Eurasian otters in urban water environments. The study is crucial as it can help rehabilitate the species' populations by identifying and managing potential Eurasian otter habitats in highly urbanized areas of the Han River basin and its tributaries.

This study aimed at comparing protected areas of Korea and Australia based on international conservation criteria by IUCN and analyzing what we need to improve for future management of protected areas of Korea. The registration status of protected areas of Korea listed on IUCN were 11 places in the Ia, 17 in II, 7 in IV, 7 in V; in total 42 places were recorded. However, the lists were missing many important areas. In Korea, we have only 4 protected area categories out of 6 indicating ecological diversity and management in its protected area system are insufficient. On the other hand, 9340 protected areas of Australia were listed on IUCN and evenly distributed in the total of six categories. Therefore, Korea should investigate measures for system establishment which ensures the diversity and indicative of our natural ecosystems and establish balanced system of protected areas including all IUCN categories I-VI through revaluation of natural, cultural, economic and social conditions and the needs.

Recently, all of the world are facing with a serious environmental crisis of global warming due to excessive energy consumptions. The Korean Government, taking over 97% of dependence on foreign energy, has made various efforts on reducing energy and greenhouse gas emission under the motto of "Low-Carbon Green Growth". Since the building sector takes 24% of domestic energy consumption, many design standards and regulations on saving energy in new buildings have been established. However, applications of energy saving designs and techniques on the remodeling process at deteriorated buildings including educational ones have been lack. Under a situation where the number of deteriorated schools accounts for up to 50%, this paper evaluated the performances of factors for reducing energy at deteriorated middle school buildings through an energy simulation tool on a standard school model. As a result, among factors of insulation, window's SHGC, southern louver, indoor setup temperature, and system efficiency, all other factors except window's SHGC and southern louver proved contribute to reduce energy at deteriorated middle school buildings, compared with the baseline energy consumption.

This research focused on the improved alternatives of the ordinance which practically control the open space in-situ, public open space and landscape construction related to city landscape for the healthy physical and mental life of the city dwellers. The contents of the study are as follows: 1. The special law of Landscape Architecture should be legislated. 2. The portion of landscaping should be changed by up-grading in the Ordinance of Landscape area and planting and the terms of landscape Facilities should include the ecological aspects in it's contents in the law. 3. The administration of local governments should actively lead and support the dwellers to make the roof gardens and the window gardens in the building area of cities or commercial districts which have relatively low rate of green space. 4. Any new construction and restoration of the buildings with preservation of the natural environment and creation of public open space should be given incentive and Set-back space in aesthetic area should have appropriate planting area and facilities in it. 5. Organizing professional landscape evaluation committee and composing evaluation standards are very important because of the contemporary proposition of the establishment of the establishment of ecological space and conservation of urban natural space. Because of the characteristics of Landscape Architecture, the Provisions of landscape Architecture Design and landscape architecture supervision of the specialist should be legislated and the Landscape Architectural Organization should be established within the Government.
