As a means to activate eco pastoral system in alpine grassland, the government can consider public pastures, which are currently unused, to scale them up into public ranches. Depending on ownership and operation, four management models proposed as follows: 1) Government-Owned and Operated with Balanced Profit and Loss 2) Government-Owned and Operated with Revenue Generation 3) Government-Owned but Privately Operated by Outsourced to Professional Manager 4) Full Privatization (Ownership and Operation by Private Individuals). The study outlined above proposes four management models for the activation of eco pastoral system in alpine grassland. It also suggests methods for the selection and performance evaluation of manager to establish a profitable structure. Additionally, the research provides management methods for the conservation of grazing ecology in pastoral ecosystems. Particularly, the adaptation of tools commonly used in South Korean business sector for the selection and performance evaluation of manager within the system of the proposed management models. This aspect is deemed valuable as it aligns these tools with the specific characteristics of eco pastoral system in alpine grassland, contributing not only to the effective implementation of the models but also to the enhancement of the revenue structure.

The two-spotted spider mite, Tetranychus urticae, and gray mold disease caused by Botrytis cinerea, are importantpest and plant disease. To control these, many people have been relied on chemical methods for a long time. However,their continuous use has resulted in resistance of pest and disease. To surmount or avoid these problems, we evaluatedantifungal activity of the selected fungi with high virulence to mite to explore the potential for the dual control of notonly T. urticae but also B. cinerea. To maximize the use of spores and cultural filtrates, the virulence to mite was evaluatedusing culture products, and effective culture condition was investigated against blastospore production and antifungal activity.Consequently, the 2 fungal isolate selected in this study were confirmed to have diverse potential and would be usedeffectively for dual control agents against the two-spotted spider mite and plant diseases

The bulb mite (Rhizoglyphus echinopus) damages garlic, shallot and onion in the bulbs, corms and tubers. It has recently become a serious problem because of the continuous use of acaricides resulting in resistance among bulb mite population. Thus, there is need to find alternative control measures to suppress bulb mite population. Here, we report the screening result of pathogenic fungi for the control of R. echinopus. Initial screenings were performed using 352 isolates of entomopathogenic fungi from Korea soils. As results, 15 isolates of acaropathogenic fungi showed the pathogenicity to bulb mite supporting fungal conidiation. These isolates were identified as 3 isolates of Metarhizium flavoviride var. pemphigi and 12 isolates of Metarhizium pingshaense by microscopic examination and genetic sequencing of the ITS region and elongation factor-1 alpha. Selected 15 isolates were tested for their virulence against adult R. echinopus and the thermotolerance and the activity to UV-B irradiation of conidia. Additionally, the activities of chitinases and proteases produced by M. pingshaense were compared according to the medium. These acaropathogenic fungi would be considered promising for biological control of bulb mite.

최근 기상학은 사회와 경제, 신재생에너지 분야 전반에 걸쳐 중요한 영향을 미치고 있으며, 효율적인 에너지 생산을 위한 기상기술 개발이 전 세계적으로 이루어지고 있다. 신재생에너지 분야, 특히 풍력에너지의 효율적 활용을 위해 독일과 미국은 고해상도(1km) 풍력자원지도를 개발하여 풍력발전단지 입지선정에 활용하고 있다. 풍력발전단지 입지에 적합한 바람은 풍속이 강하다고 이점을 갖는 것이 아니라, 평균 5m/s 이상의 빈도가 높고 풍향도 일정해야 풍력발전의 효율이 높다. 한반도는 전 세계적으로 풍력잠재에너지가 비교적 낮기 때문에 더욱 효율적인 입지선정 방법론 연구가 필요하다. 본 연구는 독일의 풍력발전단지 입지선정 평가기준을 적용하여 국립기상연구소의 풍력-기상자원지도를 활용해 한국형 입지선정 방안을 마련하는데 목적을 두고 있다.

Real estate markets play an essential role in the economic development of both developed and developing countries. Investment decisions in private real estate demand the consideration of several qualitative and quantitative criteria. Especially in Vietnam, demand for housing, apartments are rising which has resulted because of the migration from rural to urban areas. This study aims to determine the influencing factors of the real estate purchasing behavior and then recommend a grey Multi-Criteria Decision Making (MCDM) support model to evaluate real estate alternatives based on a numerical example in Vietnam. A set of essential criteria are identified based on experts’ opinion, and the proposed determinants are initial investment, maintenance cost, prestige location, distance to interesting places, parking lot, public transportation, property condition, total area size, number of rooms, and neighbors. The subjective weights were obtained by using the Decision-Making Trial and Evaluation Laboratory (DEMATEL) model, and the Grey Relational Analysis (GRA) technique is employed to prioritize and rank real estate alternatives. The results reveal that this approach can be useful to make purchasing decisions for many kinds of real estate property under uncertain business environments. These findings indicate that the presented hybrid model has advantages in granting flexibility to the preferences of decision makers.

In this study, the capacity of supplying agricultural water to 13 districts was analyzed by calculating the necessary water supply for the arable land of Gunwi-gun and examining the capacity of supplying water to reservoirs, streams, pumping stations, collection sites, and groundwater wells in Gunwi-gun. As a result, among the 13 districts the second district was found to be short of water by 1.2×106 tons/year. In general, local governments establish drought measures by selecting drought disaster risk zones. While selecting drought-risk areas, some water-poor areas that do not have water sources should be selected, even if the entire area has a sufficient water supply. The water-supply evaluation at the regional level was insufficient for locating areas without water sources, but most areas with water sources, such as streams, reservoirs, and pumping stations, were found to have no shortage of water. To locate water shortage areas without water sources, GIS analysis conducted a field survey of areas with a distance of 4 or less than that of water sources analyzed by GIS analysis. Sixty-nine sites in 13 districts were selected for the on-site survey and six areas of water shortage were identified in areas other than the second district.

Wetlands are damaged or destroyed by natural processes or artificial interferences. In order to restore their function, it is desirable to establish conservation, restoration and management measures on the basis of comprehensively collected and analyzed data of natural ecosystem characteristics and damage conditions. The purpose is to provide an evaluation index that can reflect the biological and physical characteristics such as the inhabited wildlife, degree of terrestrialization, land use change, etc. Due to the evaluation index should be simplicity of measurement, applicability, and cost efficiency as well as useful for improving the new information is obtained, so we consider the physical and biological characteristics. In order to reflect the ecological integrity and qualitative aspects such as disturbance levels, suitability as biological habitats, etc., biodiversity (landscape units, wildlife inhabit), naturalness (biotope, basin ecosystem), rarity (major plant species emergence, major animal species inhabit), and potential for damage (distribution of pollutant by distance, degree of internal damage) was selected as an evaluation index. The conservation value of Hwapo (23 points) and Samrangjin wetland (21 points), which had low number of species and populations, was low due to high potential for damage like green house, bare land etc. On the other hand, Daepyeong (34 points) and Bacsil wetland (32 points), which have worthy biodiversity, showed high conservation value, while their own area was narrow, but the endangered wildlife (Cygnus cygnus, Anser fabalis, and Euryale ferox) was appeared. Habitat disturbances, such as reduced area or internal damage, can drastic changes at population, ecosystem, and community levels. Hwapo and Samrangjin wetland, which have high damaged potential, are included. The recoverability of wetland ecosystem functions depend on the resistance and regenerative power of the system itself, so maintaining integrity of biodiversity-rich wetlands will have priority over restoration.

This study aims to develop a rational evaluation system which consists of the selection of evaluation items and the estimation of its weight for the Enhancement Program of the Quality of Life for Farmers and Fishermen and Rural Development. This system has two hierarchical steps. The first step shows the evaluation goals which are relevance, efficiency and effectiveness of the program. The second step stands for the evaluation items which have 11 sub-items such as necessity and externalization for the program, rationality of procedures, feedback and monitoring system, budgetary allocations, information activities, impacts on the program, achievements of the goals and so on. A tentative evaluation system was proposed by brainstorming and Delphi method of expert-group. Weighting values of evaluation items were calculated through pair-comparison works of expert group using stepwise matrix sheets by AHP(Analytic Hierarchy Process).
