In this study, we evaluated the antidiabetic effect of a submerged culture of Ceriporia lacerata mycelium (CL01) on hematological indices, as well as protein and mRNA expression of the insulin-signaling pathway, in db/db mice. After CL01 was administrated for 4 weeks, blood glucose levels decreased consistently, and plasma insulin and c-peptide levels each decreased by roughly 55.8%, 40% of those in the negative control (p<0.05). With regard to HOMA-IR, an insulin resistance index, insulin resistance of the CL01-fed group improved over that of the negative control group by about 62% (p<0.05). In addition, we demonstrated that the protein expression levels of pIR, pAkt, pAMPK, and GLUT4 and the mRNA expression levels of Akt2, IRS1, and GLUT4 in the muscle cells of db/db mice increased in the CL01-fed group compared to the corresponding levels in the control group. These results demonstrate that CL01 affects glucose metabolism, upregulates protein and gene expression in the insulin-signaling pathway, and decreases blood glucose levels effectively by improving insulin sensitivity. More than 90% of those who suffer from type 2 diabetes are more likely to suffer from hyperinsulinemia, hypertension, obesity, and other comorbidities because of insulin resistance. Therefore, it is possible that CL01 intake could be used as a fundamental treatment for type 2 diabetes by lowering insulin resistance, and these results may prove be useful as basic evidence for further research into the mechanisms of a cure for type 2 diabetes.

범국가적으로 지리정보시스템(GIS : Geographic Information System) 구축작업이 활성화되고 있는가운데 정부에서는 국가정보화 기반조성 차원에서 전국에 걸친 국가기본도 수치지도화 사업을 추진하고 있다. 국가기본도는 설비관리용 GIS를 구축하려는 국내 각 수요기관에서 활용되어져 GIS DB구축작업이 용이해질 것으로 예상되지만, 국가기본도에서는 각 기관에서 관리하고자 하는 모든 설비정보가 포함되어 있는 것은 아니므로 세부적인 관리대상설비의 추가 입력작업이 필요하다. 설비정보 입력은 대체적으로 각 기관에서 자체 보유하고 있는 설비도면을 기준으로 수행되지만 국가기본도와 설비도 간에는 기초 도면에 다름에 따른 설비위치 상대오차가 발생된다. 국가기본도 사용을 전제할 때 이러한 문제점은 피할수 없는 현상이며, 상대위치를 보정시키면서 관리대상 설비를 입력하려면 많은 예산과 인력이 소요될것으로 예상된다. 배전설비관리 GIS를 구축하고자 하는 한전에서는 이를 효과적으로 해결하고자 기초도면 변경에 따른 설비위치 자동보정기법을 연구하여 이를 기반으로한 시스템 개발을 완료하였다. 개발된 시스템의 정확도 및 실용화 가능성을 확인하기 위해 설비위치의 기준이 되는 전력주를 대상으로 샘플지역을 선정하여 자동보정을 실시하였으며, 현장실사를 통한 검증을 실시한 결과 약 94.6%에 달하는 보정 결과 만족도를 얻을 수 있었다.

국내에서는 1999년부터 국가수자원관리종합정보시스템(WAMIS) 구축 및 운영을 통해 물관리정보화사업을 추진하고 있으며 기초정보분석 중심에서 수자원 계획 수립과 정책 결정을 지원할 수 있는 시스템으로 확대하여 대국민 수자원 정보 제공과 홍보를 활성화하려고 노력하고 있다. 하지만 지금까지 국내에서는 수자원 현황을 평가하기 위해 상수도보급율, 하천개수율 등을 이용하여 수자원의 단편적인 분야만을 평가하여 왔으며 이들 개별지표들만으로 국내 수자원 상황에 대해 국민들이 체감하는데 한계가 있어 이들 사업의 성과를 지수화하여 수자원 정책과 사업의 효과를 국민들에게 적극적으로 홍보할 필요가 있다. 이를 지원하기 위해 2007년부터 2009년까지 수자원 각 분야별 수자원계획수립 업무지원체계를 구축하였으며 수자원 현황 평가를 위해 분야별 평가지수를 개발하고 수자원 통합지수를 선정하여 중권역별로 산정한 바 있다(건설교통부, 2007; 국토해양부, 2008, 2009). 보다 합리적인 수자원 평가를 위해서는 분야별(물이용, 치수, 하천환경) 평가 지수의 공간적 범위 확대 및 세부지표를 추가 고려함으로써 과거에서부터 현재까지의 분야별 변화 패턴을 파악해야 한다. 이를 통해 수자원 관련 정책 및 사업의 성과를 평가하고 구축된 기초자료 및 분석정보를 제공해 줄 수 있는 도구의 개발이 무엇보다 중요하다고 하겠다. 따라서 본 연구에서는 기 개발된 분야별 평가지수 산정 결과와 분야별 현황과의 비교 분석을 통해 지수의 현장 적용성을 검토함으로써 기 개발된 지표의 취약점 및 한계점을 제시하였다. 보다 합리적이고 타당한 분야별 평가를 위해 세부지표를 추가로 선정하였으며 선정된 분야별 세부지표를 PSR 구성체계에 맞추어 구성하였다. 또한 분야별 현황 및 특성을 평가할 수 있는 분야별 평가지수를 개발하였으며 물이용 특성을 평가할 수 있는 지수를 '물이용안전성지수', 치수 특성을 평가할 수 있는 지수를 '홍수안전성지수', 하천환경 특성을 평가할 수 있는 지수를 '하천환경건강성지수'라 명명하였다. 또한 분야별 평가지수를 통합하여 수자원 현황을 평가하고 관리할 수 있는 수자원 통합지수인 '물만족지수'를 개발하여 제시하였다. 분야별 평가지수를 구성하는 각 세부지표의 특성을 파악하여 지표 산정 범위를 점, 선, 면으로 확대하여 제시하였으며 세분화된 공간단위별로 기초자료를 조사, 수집하여 시계열 DB를 구축하였다. 개발된 분야별 평가지수 및 물만족지수를 연도별 표준유역별로 구축된 DB를 이용하여 산정하고 비교 분석하였으며 상대적인 분야별 안전성 및 건강성을 평가하여 지수의 적용성을 검토하였다. 지표 관련 기초자료 및 분석을 통해 생성된 정보자료는 수자원정책 수립과정에서 매우 유용한 정보를 제공해 줌으로써 정책결정을 지원할 수 있고, 일반인과 관련 전문가들에게 수자원 관련 다양한 정보를 제공할 수 있다.

In Korea, previously implemented road construction project caused a big budget waste due to overestimation of transport demand. There could be reasons for such inaccuracy of transport demand estimation, but the main reasons are: (1) low reliability of used basic road transport data and (2) inadequate sharing of data among agencies/departments. The National Transport Database and the Household Travel Database in Seoul Metropolitan Area, two representing basic road transport database, will be used to the establishment of a road construction plan that will be promoted afterwards. However, these materials have problems such as low reliability and inadequateness, too. Hence, focusing on transport demand estimation related databases, this paper will make proposals for enhancing their reliability and data sharing.

In order to restore an ecologically damaged river, freshwater fish which inhabit at the target aquatic ecosystem have a great applicability as one of the essential indicators. Although the informations about the habitat conditions of freshwater fish are key elements reflecting biological, physical, and chemical properties of the aquatic environment, because of the lack of preceding related research and insufficient database with scattered data, they have not been applied effectively for the ecological river restoration projects in Korea. To cope with these problems, based on the nation-wide detailed investigation for domestic freshwater fish habitat conditions, we have selected 70 species considering the possibility for the candidates of flagship species, constructed a database for their population, physical, and chemical habitat properties, and suggested its application methodology for the river restoration projects. In particular, the utilization of the database has been enhanced by the additional statistical analysis to present their resistance and optimum ranges for physical, and chemical habitat properties respectively. It is expected that the database constructed in this study can be utilized for the calculation and evaluation of the appropriate ecological flow rate and target water quality for the selected flagship species (fish), and the basic data for the restoration of river environment.

Due to its excessive $CO_2$ emissions, road transport sector becomes a target for emission reduction strategies. Although precise and reliable emissions inventories are necessary for evaluating plans and strategies, developing the region-wide inventory is a difficult task mainly because of a lack of data including travel patterns and modal volumes in the reginonal context. Most existing inventory methodologies employ fuel sale data within the target region, which ignores actual regional traffic patterns and thus not suited to its geographical context. To overcome these problems, this study develops region-wide $CO_2$ emissions inventory methodology by utilizing the Korea Transport DB (KTDB). KTDB provides a number of useful information and data, such as road network with which one can identify in and out trips over the entire region, traffic volumes of various modes, distance of travel, travel speed and so on. A model of equations that allow the computation of volume of $CO_2$ emitting from the road transport activities within the target region is developed. Using the model, numerical analyses are performed for the case of Busan Metropolitan City to demonstrate the applicability of the developed model. This study is indeed exploratory in the sense that using the existing data, it develops the $CO_2$ emissions inventory methodology which can produce better results than those from conventional fuel sales methodology. This study also suggests further reresarch directions to develop more refined methodologies in region-wide basis.

This study developed an ecological mapping technique with GIS database using the analyses of existing ecological survey reports and the change detection on the Nakdong river estuary. The data which are used to establish GIS DB include 2 Landsat TM images on Nov. 31, 1984 and May 17, 1997, 1:25,000 topographical maps established by National Geography Institution and various ecological survey reports published by Busan metropolitan city government. The details for producing ecological map are as follows. At first, the current methods of ecomapping efforts and previous ecological surveys of Nakdong river estuary were carefully examined. Secondly, the land cover maps were created from the classified Landsat images of 1984 and 1997 for the spatiotemporal ecosystem analysis. Thirdly, the ecosystem was evaluated by using GIS ecological database based on the criteria of botany, zoology and water quality etc. Each criteria was reclassified into 3 stages which describe the overall quality of ecological condition. At last, the comprehensive ecological map was suggested as a prototype of ecosystem assesment and management tool with the discussion of further study. The findings of this study would be a milestone for preserving and managing the ecosystem.
