The Seocheon and Yubu Island mudflats in Geum Estuary are important stopover sites for migratory birds as energy supplementation area in the East Asia-Australasian Flyway. Benthic invertebrates in the tidal flats are important food resources for the migratory birds. In other words, benthic invertebrates in the tidal flats play an important ecological role in energy flow. This study was conducted to investigate the relationship between benthic invertebrate assemblages and environmental factors in Seocheon and Yubudo tidal flats in the Geum Estuary. As a result of the benthic invertebrate assemblage during the fall migration season, the total species number was 147, density and biomass were $1,772{\pm}1,342individuals/m^2$ and $445.1{\pm}807.6g/m^2$, respectively. Based on the appearance species and the density data, the result of analysis of mutual similarity among sampling sites was divided into two groups. Group A was the Macrophthalmus-Heteromastus community and Group B was the Spio-Urothoe-Mandibulophoxus community. Group B showed higher mean species number, density and biomass than Group A. The BIO-ENV analysis showed that the benthic invertebrate assemblages were most affected by the combination of sand content % and sediment sorting (${\rho}=0.500$). The variables of significant relationship with species number and biomass were sediment sorting (p=0.015) and the pore water DO(Dissolved Oxygen, p=0.003) in sediment, respectively.

This study aims to suggest the necessary political implications for the introduction of green tourism in "Mountain Village Project" through the survey of local residents on the recognition of rural and mountain villages about the Village Development Projects. Direct survey using a structured questionnaire was executed to each local resident in different types of rural tourism villages such as the Mountain development village, the Green agricultural village, the Rural theme village, and mixed type of village between them. It was revealed that local residents in the Mountain development village had a positive reaction to the Project, whereas those in mixed type of village did not notice highly the change by the Project. Residents in the Mountain development village highly satisfied with the Project as improved income sources. In addition, it was shown that local residents recognised the necessity of social education and they highly wanted to participate in it. Residents in the Green agricultural village also wanted to put an effort to introduce an activity-based program for village development.

Purpose : This study aimed to propose a common scope of practice (SOP) for 13 specialties of Advanced Practice Nurses (APNs) in Korea. Methods : The first draft of a common SOP was extracted from domestic and international laws with a literature review by 17 experts from the Korean Association of Advanced Practice Nurses (KAAPN). Then, the common SOP was finalized after comparing the activities of APNs in clinical settings. Results : A total of 70 duties were identified and six categories were suggested for the common SOP. The SOP proposed by the KAAPN featured the following: 1) identification of and discrimination between health problems; 2) prescription and implementation of diagnostic tests; 3) treatment of injuries and diseases while implementing measures to prevent exacerbation; 4) prescription of medicinal products in line with 1) to 3); 5) referral and consultation; and 6) education and counseling. It was then confirmed that the proposed six categories in the common SOP reflected all the duties performed by APNs in clinical practice, including all 40 activities. Conclusion : The results of this study can be used as evidence for the legalization of a common SOP for APNs. Given the increasing multidisciplinary team approach adopted in Korean hospitals, it may be desirable to establish a broader SOP to reflect the diverse duties of APNs.

The acute toxicity of several pesticides on 4 Korean water flea was investigated to develop a new standard species used for ecological risk assessment of pesticide. Four Korean freshwater cladocerans, Daphnia obtusa, Daphnia sp., Moina macrocopa and Simocepholus vetulus were exposed to five different pesticides during 48 hours to compare their sensitivity with a standard test species, Daphnia magna, endorsed formally by the major international organizations. The synthetic pyrethroid, fenpropathrin was the most toxic pesticide to cladocerans. Diazinon, carbofuran, iprodione and myclobutanil were in the order of their toxicity to cladocerans tested. There was no consistent difference in sensitivity to five pesticides for four Korean cladocerans tested. In conclusion, the ecological risk assessment using single species toxicity referred to base set data should not be enough to protect to every species in the field environment.

Nowadays, in the European countries, landscape is spoken of its importance as often as environment, by those who are engaged in such fields as politics, administration, research and civil society. In Korea, while recognizing such an international trend, academics and administrators have made a series of efforts to reflect landscape concept on a variety of policies. However, it is recognized that the effects of these policies have not been satisfactory. Under these circumstances, this paper aims to examine the complex values and multiple meanings in the landscape, which have been discussed by landscape experts in the European countries. Then, it aims to the explore the future direction of policy and research on the landscape to be pursued in Korea, where there is relatively less interest in the issues of landscape. It is argued that landscape should be approached and understood from a holistic perspective, because it is a very complex concept with multiple meanings that have been coined differently depending on the situation. All the academic fields, involved in the landscape research, should try in co-operation to develop the comprehensive approach rather than the inter- and multi-disciplinary approach to the landscape study. In Korea, moreover, it is also necessary in the legislation to recognize the fact that degradation and retreat in the quality of landscape would make a negative effect on the quality of human daily life. Natural and cultural heritages contained in the rural landscape are also now in danger of disappearing. These heritages, therefore, should become an important subject for research and policy on landscape before the countryside is completely evacuated after the aging population die out. To make this happen, it is very urgent that evaluation and classification of landscape character should be undertaken from the holistic perspective, which is equipped with a methodology overcoming as well as encompassing the boundaries of academic fields. It is also equally very urgent that education on landscape should be provided to the politicians, citizens and students as well as the officials dealing with landscape matters. Finally, government should strive to make the landscape concept penetrate deeply as well as widely into the spatial planning and legislation process while designing and implementing a comprehensive landscape policy at the national level.

In order to simulate a typhoon precisely, the satellite observation data has been assimilated using WRF (Weather Research and Forecasting model) three-Dimensional Variational (3DVAR) data assimilation system. The observation data used in 3DVAR was GPS Radio Occultation (GPS-RO) data which is loaded on Low-Earth Orbit (LEO) satellite. The refractivity of Earth is deduced by temperature, pressure, and water vapor. GPS-RO data can be obtained with this refractivity when the satellite passes the limb position with respect to its original orbit. In this paper, two typhoon cases were simulated to examine the characteristics of data assimilation. One had been occurred in the Western Pacific from 16 to 25 October, 2015, and the other had affected Korean Peninsula from 22 to 29 August, 2012. In the simulation results, the typhoon track between background (BGR) and assimilation (3DV) run were significantly different when the track appeared to be rapidly change. The surface wind speed showed large difference for the long forecasting time because the GPS-RO data contained much information in the upper level, and it took a time to impact on the surface wind. Along with the modified typhoon track, the differences in the horizontal distribution of accumulated rain rate was remarkable with the range of -600~500 mm. During 7 days, we estimated the characteristics between daily assimilated simulation (3DV) and initial time assimilation (3DV_7). Because 3DV_7 demonstrated the accurate track of typhoon and its meteorological variables, the differences in two experiments have found to be insignificant. Using observed rain rate data at 79 surface observatories, the statistical analysis has been carried on for the evaluation of quantitative improvement. Although all experiments showed underestimated rain amount because of low model resolution (27 km), the reduced Mean Bias and Root-Mean-Square Error were found to be 2.92 mm and 4.53 mm, respectively.

This study is to analyze environmental problems which have caused by changes of the population and agriculture in North Korea. Main results of the research are following. First, Population of the North Korea shows lower increase ratio less than 2% growth from 1970's to middle of 1990's. This is interpreted by food shortages. Second, population distribution by provinces represented that northern and eastern part of the North Korea were comparatively lower and other western areas were higher. Third, Food situation of the North Korea was relatively better in 1970's, but, 1990's was the worst in the way. Fourth, on the agricultural productivity according to each province, western areas possessing more plains were more higher than mountainous areas of the northern and eastern parts of North Korea. Fifth, Growth ratio of food production and population have grown very steadily until 1990's, but the increase ratio of population exceeded food productivity after 1990's. Sixth, Cropland reclamation for improving these situation have caused deforestation and environmental problems and especially eastern and northern areas became more serious. For the solving these problems of North Korea, it is necessary to get the help of South Korea and international societies with efforts by itself.
