  • Apsan, as part of the main ecosystem of Daegu city, plays an important role for maintaining the environmental sustainability of the large city. Especially varieties of valuable resources, which are cultural, historical, biological, geomorphological and geological, are distributed around Apsan. Therefore the positive preservation plan is required. This paper aims to examine the environmental characteristics of Apsan and then suggests the following ideas for the environmental preservation and sustainable use of Apsan. 1) 'The New Map of Apsan' that includes more exact information needs to be produced. 2) The Apsan ecosystem management plan should be made under the precision natural ecology investigation. 3) For the protection of inanimate object resources, such as geographical feature and geology, the Geotourism Department needs to be established within Daegu metropolitan office of education or the tourism division of Daegu city government. 4) An effective environmental-impact-assessment system should be officially established. 5) the positive administrative and financial support system led by local NGOs is required for the Apsan environmental protection activities and education. 6) It is necessary to bring out into the open prayer sites to prevent forest fire. 7) 'The nature rest year system' enforcement is required to restore the damaged ecological space of Apsan.

  • 생태학 분야에서는 생물의 분포, 변동, 서식환경요인의 변화, 등의 여러 종류의 데이터들이 수집되고 있는데 데이터의 형태가 다양하여 데이터의 관리와 활용형태도 다양하게 나타나고 있다. 근래에 들어 각 종 측정기기들이 개발되면서 생태조사 분야에서도 데이터의 양이 급증하는 시점에 있다. 수생태계 분야에서도 전통적인 생물상조사의 데이터는 크게 증가하지 않고 있지만 자동측정센서가 개발된 항목의 경우에는 데이터가 급증하는 단계에 있다. 수생태계에서 흔히 조사되는 플랑크톤의 군집구조 자료를 보면 하나의 조사대상 시료에서 출현하는 종의 수가 50 종정도에 이르며 각 개체의 종을 육안으로 확인하고 있으므로 종조성조사는 아직 자동화가 어렵다. 그러므로 플랑크톤 자료의 특성은 조사의 시료수(case)는 적고 측정항목(변수 variable)이 많은 특성을 가진다. 반면에 센서가 개발된 수질과 관련된 항목들은 자동측정설비가 확대되고 있어 변수는 적지만 장기간의 time series 들이 수집되고 있다. 녹조현상이 관심을 끌면서 여러 곳에 식물플랑크톤의 양을 측정하는 chlorophyll 센서가 설치되고 있는 것이 대표적인 사례이다. 그 외에 정량화되지 못하는 정성적 자료들도 수집되고 있으며 자료수집방법의 표준화도 미흡한 예가 많이 있고, 자료의 형태가 다양하여 데이터의 관리와 활용을 어렵게 한다. 환경부는 전국의 주요 하천 지점에서 정기적으로 수질을 측정하여 공개하고 있으며, 일부 지점에는 자동수질측정시설을 설치하여 측정의 빈도를 높이고 있다. 하천이나 호수에서 센서를 이용한 고빈도 모니터링은 그 동안 인지하지 못하였던 단기적 생태계 변화에 대해 새로운 정보를 제공하여 연구의 장르를 넓혀 가고 있다. 도시하천에서 산소를 측정한 사례를 보면 강우 시에 일시적으로 산소가 고갈되는 현상이 관찰되며, 부영양한 호수와 하천에서는 주야간 산소의 급격한 변동이 생태계 스트레스 요인으로 작용하고 있음을 알 수 있었다. 식물플랑크톤 센서의 연구에 의해 단기적인 변동이 크게 나타나고 있음이 새로이 밝혀지기도 하였다. 데이터의 수집과 활용도를 높이려는 노력도 이루어지고 있다. 과거에는 개인단위로 이루어지던 연구가 이제는 데이터를 수집하고 공유하는 플랫폼이 만들어 지면서 공동연구가 확대되고 있고, 국제적으로 지역을 초월하는 공동연구도 가능하게 되었다. 국제호수관측망학회(Global Lake Ecological Observatory Network, GLEON)이 그 사례이며 세계 여러 나라의 학자들이 참여하여 국제적으로 데이터를 공유하고 공동연구를 촉진하는 역할을 하고 있다. 생태계데이터의 증가는 생태학자들의 연구역량을 초과하는 데이터의 관리와 활용의 능력을 요구할 것이며 환경 생태 IT 분야의 융합연구의 필요성이 크게 대두되고 있다. 그간 데이터베이스의 구축에는 일부 성과가 있었으나 아직 수집된 데이터의 활용도를 높이고 타분야와의 협력연구 시너지를 확대하려는 노력은 부족하다. 이제는 데이터의 수집과 저장뿐 아니라 데이터의 활용도를 높일 수 있도록 학제적 협력연구를 촉진하는 off-line 모임도 확대할 때이다.

  • u-Society 구현을 위한 IT 발전전략은 경제 재도약을 위한 IT 산업정책에의 요구 종대, 디지털 컨버전스 추세의 강화, IT의 사회전반에의 영향력 확대라는 세 가지 환경변화를 감안하여 수립 추진되어야 한다. IT 산업정책에의 요구 증대에 부응하기 위해서는 IT를 중심으로 하는 신성장 동력을 강화해야 하는데, 구체적으로는 IT 원천기술 투자비율을 단계적으로 증가시키고 기존산업과 IT의 융합 분야의 창의적인 R&D 과제를 발굴하고 국제화된 IT인력을 양성하는 것이 중요하다. 또한 한국형 벤처 생태계를 조성하여 소프트웨어 및 컨텐츠 부문을 육성시키는 것이 필요하다. 디지털 컨버전스 추세에 대응하기 위해서는 진입장벽의 완화, 수평적 규제체계의 적용, 방통융합 서비스의 조속한 도입 및 규제기구의 통합이 선결과제이다. IT의 사회전반에의 영향력 확대를 경제 및 사회 제분야의 발전으로 연결시키기 위해서는 물리적인 광대역 인프라의 구축에 더하여 정보사회의 역기능 방지 및 정보보호체계 강화, 정보화추진위원회의 기능 강화가 요구된다. 또한 비IT부문에의 IT접목과 더불어 복지, 교육, 공공부문 혁신에 If를 적극적으로 활용하여야 한다. 즉, u-Society구현은 기존의 정보화정책의 한계를 넘어, 물리적인 인프라 구축과 보완 제도, 규제정책, 산업정책의 유기적인 조화를 필요로 하며 이러한 노력이 결실을 맺을 때 우리나라는 경제적 풍요와 수준 높은 삶의 질을 향유할 수 있을 것이다.

  • This paper criticized the recent Korean 'creative economy policies' focused on regional developmental implications. Even though the policies targeted to promote ICT new startups and build virtuous circle of ICT industrial ecosystem in Korea as a whole, the outside regions of the Seoul-Busan industrial axis where the bases of ICT industries are very weak would suffer from systematic exclusion in ICT investments and deepening regional disparities. Second, ICT-centered policies would selectively affect or operate commensurate with the size of regions in this low-growth, after-financial crisis age. Third, the possibilities of regional insularity and lock-in in these low levels of 'related variety' regions would worsen the industrial competitiveness. Lastly, the policies should be reoriented to fortify region-based creative economic ecosystem based upon triple helix learning region.

  • Numerical study on coastal water quality management was conducted to examine the response of summer water quality to the flow into the sea of land based pollution load in Ulsan Bay, Korea The abatement of pollution load. from point sources of land was estimated on the basis of Korean coastal water quality standard using an ecosystem model. The results of the ecological model simulation showed that COD values in the inner part of the bay were greater than 280mg/L, and exceeded the grade III limit of Korean coastal water quality standard 30% of all land based pollution loads or organic and inorganic material loads from point sources should be cut down to keep the COD levels below 2mg/L. As environmental carrying capacity was estimated to be 7,193kgCOD/day to keep the COD levels below 2mg/L in Ulsan Bay, 3,083kgCOD/day of land based organic loads should be reduced. The phytoplankton blooms have occurred in the Teahwa river mouth or estuary repetitively, so it is important to control land based nutrients loads for removal of autochthonous organic loads around Ulsan Bay.

  • The purpose of this study is to critically evaluate the DPD development plan of Kyungpook province, which was established in 1996 and slightly revised in 1997 in terms of a theoretical framework, fair distribution and ecological sustainability, and the feasibility of capital supply of the proposed plan. The early part of the proposed plan introduces various theories and approaches developed in regional (or local) development planning as a general after the 1970s. However, the theories and approaches mentioned are not used as a guideline to establish the DPD development plan of Kyungpook province as a historically developed particular place. Most of the plans were tourism-oriented and did not seriously take the local characteristics into account. All the DPDs of Kyungpook province are located in the upper parts of the Nakdong River basin. So those regions are ecologically vulnerable. But a lot of problems remain concerning the environmental impacts of the proposed development plan. In terms of fair distribution and ecological sustainability, it seems that the DPD development plan was routinely made by a handful of professors and administrators, based on a standard format of regional (or local) development as a genera]. Finally, capital is the key factor for successfully implementing the DPD development plan. It came from the national and local government and private investors. The government have generally financed the construction of infrastructures, not profit-oriented projects such as tourism and resort businesses. However, the feasibility of private capital was not carefully examined in the plan.

  • In the smart media environment, magazine industry has been experiencing a transition to ecosystem of value network, which includes high complexity and ambiguity. Using case study method, this article conducts research on digital convergence, the model of magazine ecosystem and adaptation strategy of global magazine companies. Research findings have it that the way of contents production of global magazines has been based on collaborative production system within communities, expert communities, creative users, media contents companies and magazine platform. The system shows different patterns and characteristics depending on magazine-driven platform, Platform-driven platform or user-driven platform. Collaboration system has been confirmed in various cases: Huffington Post and Zinio which collaborate with media contents companies, Amazon magazines and Bookish with magazine companies, Huffington Post and Wired with expert communities, and Flipboard with creative users and communities. Foreign magazine contents diverge into (paper, electronic, app and web magazine) as they start the lively trades of their contents on the magazine platform. In the area of contents uses, readers employ smart media technology effectively such as cloud computing, artificial intelligence and module individualization, making it possible for the virtuous cycle to remain in the relationship within communities, expert communities and creative users.

  • In general, design education related to transportation has been recognized as a department specialized in transportation design or as an area of detailed transportation majors within industrial design majors. However, as technological, social, and environmental factors change, the concept of mobility and the ecosystem related to the mobility industry are diversifying, and accordingly, the category of mobility-related design is expanding further. Based on this background, this study is not a mobility design major, but it aims to find implications by analyzing the trend and type of topic selection related to the mobility ecosystem among the last five years of graduation design topics conducted in the design engineering major. As a result of the study, of a total of 131 graduation design works conducted over the past five years, about 30 works were highly related to mobility, and their types were very diverse. In conclusion, it was confirmed that the change and expansion of the mobility ecosystem expanding from products to services and systems were also reflected in the selection of graduation works in that various topics approached from user-centered and user experience were proposed and made into works.

  • Currently, there is increasing demand for weather information, however, providing meteorology and climate information is limited. In order to improve them, supporting the meteorology and climate big data platform use and training the meteorology and climate big data specialist who meet the needs of government, public agencies and corporate, are required. Meteorology and climate big data requires high-value usable service in variety fields, and it should be provided personalized service of industry-specific type for the service extension and new content development. To provide personalized service, it is essential to build the collaboration ecosystem at the national level. Building the collaboration ecosystem environment, convergence of marine policy and climate policy, convergence of oceanography and meteorology and convergence of R&D basic research and applied research are required. Since then, demand analysis, production sharing information, unification are able to build the collaboration ecosystem.
