  • 기업의 지적자산을 효과적으로 관리하는 지식경영 차원에서 기업들은 디지털 시대에 부합되도록 다양한 종류의 지식을 창조해내는 디지털 창의성을 기반으로 한 지식 경쟁력 향상 방안을 요구하고 있다. 이에 본 연구에서는 디지털창의성의 개념을 정의하고 이들에게 영향을 미치는 구성요인으로 디지털환경, 전문성영역, 디지털리스트성향을 제시하고 구성원의 다양성에 따른 디지털 창의성 변화와 경영성과에 미치는 영향을 다중 에이전트 시뮬레이션 접근방법을 사용하여 분석 하였다. 분석결과 구성원의 다양성이 높은 집단일 경우 시간의 흐름에 따라 구성원의 다양성이 낮은 집단, 즉 동질성이 높은 집단 보다 지식관리시스템 (KMS)을 이용한 지식의 생성 및 공유와 디지털창의성에 영향을 주는 강도가 높은 것으로 나타났다. 또한, 전문성영역, 디지털리스트성향이 디지털 창의성에 유의한 영향을 미치며, 디지털 창의성도 경영성과에 유의한 영향을 미치는 것으로 나타났다. 이러한 결과를 바탕으로 디지털 창의성과 경영성과 향상에 대한 시사점 및 향후 연구방향을 제시하였다.

  • 최근 우선 네트워크 상에서 이동성을 보장하기 위한 다양한 인프라 기술에 대한 연구가 활발히 진행되고 있다. 한국군 전술통신망은 이기종, 다특성 통신장비로 구성된 네트워크가 복합적으로 운용되고 있다. 임무수행을 위한 신속한 상황인식과 지휘통제가 최상위 지휘관으로부터 이동중인 최하위 전투원까지 이음새없는(seamless) 통합망을 통해 전달되어야 하나 현재 각 네트워크간 통합기술이나 통합 아키덱처에 관한 연구는 미흡한 실정이다. 본 논문에서는 현재 가용한 이동 네트워크 기술 현황을 제시하고, 현 한국군 전술통신망의 특징과 장단정을 제시한 후, 복합적인 네트워크 환경 하에서 노드의 이동성을 지원하는 계층적 전술통신망 아키텍처에 대한 통신망 설계시 고려사항, 전체 아키텍처 구조 및 각 계층별 노드의 구조와 이들 노드간의 인터페이싱, 이동노드에 대한 이동성 관리 방안을 제안한다.

  • Humans and wild birds coexist in cities, where habitat fragmentation due to urbanization threatens the habitat and movement of birds. In this study, in order to identify landscape features associated with wild bird collide, we characterized landscape composition within a 500 m radius and points of wild bird carcasses in Suwon-city, South Korea. Dead birds were identified as having a Normalized Difference Vegetation Index (NDVI) of 0.3, Normalized Difference Built-up Index (NDBI) of -0.05, and Normalized Difference Water Index (NDWI) of -0.16 at the points of collide. And there were NDVI of 0.34, NDBI of -0.01, NDWI of -0.18, building height of 13.8 m, and soundproof wall length of 227.3 m within a radius of 500 m. Land cover type was dominated by grassland, used area, and bare land. In particular, the edges of urbanized areas, where apartments bordered forests, reservoirs, and golf courses, were identified as high-risk spaces. In order to minimize bird mortality risk in urban environments, the impact of changes to a vertical landscape should be reviewed from an environmental impact assessment approach. In addition, a preventive management plan that considers the temporal and spatial features that wild animals can safely avoid and adapt to in urbanized spaces should be prepared.

  • The Yellow Sea Ecoregion Conservation Project is a joint international project which is carried out under the purposes of conserving the habitats in the Yellow Sea Ecoregion and biodiversity from various threats that damage ecosystems, informing the importance and value of the Yellow Sea Ecoregion, and promoting the understanding and interests of Korea, China and Japan. Subsequent to the Yellow Sea Ecoregion Planning Programme which had been performed during the period from 2002 to 2006, the Yellow Sea Ecoregion Support Project has been performed over 7 years in total from 2007 to 2014. Panasonic is sponsoring the financing of the project, and the organizations in charge of the project by country are Korea Institute of Ocean Science & Technology for Korea and World Wide Fund for Nature branches for China and Japan. While the Yellow Sea Ecoregion Planning Programme was focused on the biological assessment and the selection of potential priority area by scientific review, the Yellow Sea Ecoregion Support Project is oriented toward practical activities targeting more diversified stakeholder. Especially, this project plans to support direct conservation activities in the region and participation and cooperation from local residents. The project plan is comprised of 3 phases. During the first period from 2008 to 2009, small grant projects were operated targeting 16 institutions of Korea and China, and for the second period from 2010 to 2012, one place each was selected as demonstration site for habitat conservation in Korea and China respectively and supported for three years to introduce the conservation method based on international standards such as the management of marine protected areas, ecosystem-based management and community-based management and simultaneously to develop habitat conservation activities suitable for national and regional characteristics. During the period from 2013 to 2014 which is the last phase, the project plans to distribute the performance of small grant projects and demonstration site activities through a series of forums among stakeholder. Through the activities described above, the recognition of general public on the conservation of the Yellow Sea Ecoregion was changed positively, and community-based management began to be reflected in the policies for the marine protected areas of central and local government.

  • The sprig of Jinryungtang Gagambang has been used for curing as a traditional medicine without any experimental evidence to support the rational basis for their clinical use. This experiment was carried out to evaluate the possible therapeutic or antitumoral effects of Jinryungtang Gagambang extract against cancer, and to study some mechanisms responsible for its effect. The cytotoxic and antitumor effects were evaluated on human cell liens (A549, hep3B, Caki-1, Sarcoma 180) after exposure to Jinryungtang Gagambang extract using in ILS, colony forming efficency and SRB assay which were regarded as a valuable method for cytotoxic and antitumor effects of unknown compound on tumor cell lines. The results obtained in this studies were as follows. 1. As a result of exposure to Jinryungtang Gagambang extract, the proliferation of A549, hep3B, Caki-1, good correlations were shown from the results of SRB assay and those of clogenetic assay. 2. The oral administration of Jinryungtang Gagambang extract showed significant effects of increase of MST(mean survival time) and ILS(increased life span) depending on the increasing concentration. 3. Against squamous cell carcinoma induced by MCA, Jinryungtang Gagambang decreased not only the frequency of tumor production but also the number and weight of tumors per tumor bearing mice(TBM). Jinryungtang Gagambang also significantly suppressed the development of 3LL cell-implanted tumors by frequency and their size, and some developed tumors were regressed by the continuous treatment of Jinryungtang Gagambang extract into TBM. 4. Jinryungtang Gagambang extract also increased NK cell activities. According to the above results, it could be suggested that Jinryungtang Gagambang extract has prominent antiutmor effect.
