The social service delivery system has had problems of low efficiency and effectiveness because of service discontinuity, redundancy and incomprehensiveness for a long time. A model of Health and Social Welfare Office was implemented in order to solve these problems but stopped its operation without being expanded nationally in 1990's. In 2004 a new experiment of the Social Welfare Offices was launched to solve the problems. One of the important goals of the new experiment of the Social Welfare Offices was to reinforce autonomy and accountability of the local governments in providing various social services and social welfare benefits, to deliver coordinated services and to activate participation of the local people for development of social welfare through construction of the cooperative system among the central government, the local government and the social welfare institutions in the private sector. This paper analyzed how different linkage of financial resources in the social service network for the elderly was between the experiment and the control areas during the second experimentation period of the social welfare offices. It compared the organizational characteristics of the social service network for the elderly, frequency and density of networking, and degree centrality of the networks between the experiment and control areas. The findings show that the social welfare offices are playing a very important role in activating networking. However, it is difficult to conclude that the experimentation caused the difference in networking between the two areas because the research design did not take before and after comparison for the experiment and control areas. Discussion can be advanced if the results of the qualitative study would be compared with the findings of this study.

본 연구는 2004년도 2월에서 3월까지 철원분지의 민간인통제지역에서 두루미와 재두루미의 차량에 대한 반응 행동과 함께 방해요인과 먹이와의 수지균형에 관하여 실시하였다. 재두루미의 도로로부터의 평균취식거리는 두루미에 비하여 가까웠다. 두루미와 재두루미 모두 무리크기가 클수록 도로로부터 떨어진 평균거리는 증가하였다. 두루미와 재두루미는 차량의 근거리 정지에 대하여 경계, 걷기, 뛰기, 비행의 반응을 보였으며, 도로에서 가까울수록 차량에 대하여 민감하게 반응하였다. 도로에서 멀수록 차량의 정지에 대한 반응 시간은 두루미와 재두루미 모두 감소하였다. 차량의 정지에 대하여 반응을 보이지 않는 반응역치거리는 두루미와 재두루미 모두 250m이었다. 두루미는 200m내에서 재두루미에 비하여 민감하게 반응하였다. 도로 교통량이 증가함에 따라 동일거리에서의 반응시간은 변화가 없었지만, 도로인근 지역에서 멀어지게 하고 해당지역을 취식지로 이용하지 않게 하는 영향이 있었다. 두루미와 재두루미가 차량 통행 등의 방해요인에도 불구하고 낙곡을 취식했던 것은 도로인근 지역의 잔존 낙곡의 밀도가 높았기 때문이었다.

DPPH(l, 1-diphenyl-2-picrylhydrazyl) free radical scavenging activity assay was used to analyze antioxidant activities in 78 pigmented rice germplasms. Out of 79 varieties taken, 28 varieties showed >70%, 27 varieties showed 61-70% whereas the rest of the varieties showed less than 60% antioxidant activity. In relative total anthocyanin content, Tingga loko( 1.972mg%), Ane bonak(l.965mg%), Pulut mbiring(1.926mg%), and so on were present at concentration given in the descending order, which lies within the range of 0.028 -1.972mg%.

DPPH(l, 1-diphenyl-2-picrylhydrazyl) free radical scavenging activity assay was used to analyze antioxidant activities in 249 Korean rice landraces. Especially, red rice varieties were 13 accessions, showed very strong antioxidant activities more than 95%. Brown rice varieties were 236 accessions, among them G307 showed the highest antioxidant activity of 68%. Most of brown rice varieties showed higher activities than Chucheongbyeo as check variety. 101 accessions were distributed range of 21 - 30% and 71 accessions were distributed range of 31 -40%.
