전 세계적으로 OTT 서비스가 대중화됨에 따라 새로운 콘텐츠가 끊임없이 유통되는 플랫폼 미디어 산업 생태계에서 콘텐츠 IP 확장 전략은 콘텐츠 제작방식에 있어 중요한 위치를 갖는다. 그 중에서도 특정한 세계를 구성하는 구성요소, 즉 세계관을 확장하는 방식은 콘텐츠 IP 전략에서 위험요소를 줄이고 콘텐츠 프랜차이즈를 구축하는데 있어 효과적이다. 본 연구는 마블의 영화적 세계관(MCU)이 어떻게 멀티버스 개념을 차용하여 자기 스스로 이를 복제하고 재생산하면서 콘텐츠 IP 확장을 전략적으로 수행하고 있는지 <로키(Loki)>의 서사 분석을 통해 살펴보고자 한다. 결과적으로 멀티버스 세계관은 완결된 사건을 반복하여 비/완결 상태를 재생산 할 수 있고, 이는 완결된 또 다른 자기충족적 콘텐츠로 존재가능하다. 동시에 멀티버스 세계관 아래 하나의 캐릭터가 다수로 존재 가능하기 때문에 복수의 이야기를 생산해낼 수 있다는 점에서 효과적인 콘텐츠 IP 확장전략이 될 수 있다.

This study was surveyed from May to October, 2008 in order to classify type distribution and evaluate the function of inland wetland as a ecological axis in Chungnam province. Assessment was done by modified-RAM (Rapid Assessment Method). RAM is consisted of total 8 functions and divided into high, moderate, low. The conservation grade of RAM is divided into 4 grades; absolute conservation, conservation, improvement and restoration. Throughout survey on total 13 wetlands of Lacustrine, Palustrine wetland which are distributed in Chungnam province, their function was assessed. As result, the 2 wetlands were judged as absolute conservation grade by assessment of 8 functional contents, and 7 sites were improvement wetlands and 4 sites were conservation wetlands. The function of wetlands assessed as conservation grade showed high in water quality protection and improvement. Also, showed high in vegetation diversity, wildlife habitat and aesthetic recreation. Meanwhile, showed low in Water quality purification, Shoreline/Stream Bank Protection. Of wetlands evaluated as conservation grade, Jeong-juk Ji and Dun-ri reservoir were assessed as absolute conservative area. These wetlands are essential to be managed continuously as a area having high ecological value. Farther, these wetlands will be done as a axis of ecological network related to 'Kumbuk jeongmaek' ecosystem.

환경평가에 생물다양성 손실을 최소화하기 위한 가이드라인을 적용하고자 하는 노력이 외국에서 진행 중이지만 국내에서는 고려의 대상이 거의 되지 못하고 있다. 이러한 상황이 지속되면 우리나라의 생물다양성이 급격히 감소할 것이다. 따라서 우리도 생물다양성의 손실을 최소화하도록 지침을 준비하는 것이 시급한 실정이다. 본 연구에서는 현재 환경영향평가 시스템의 잠정적인 문제를 평가하고, 현재 시스템에 생물다양성/생태계 항목을 어떻게 도입할 것인가에 대한 정보를 제공하기 위해 고속도로 건설사업에 대한 32개의 환경영향평가서를 분석하였다. 평가서의 분석에서 서식지 및 생물다양성을 다루는 경우는 드물었고 생물다양성 이슈들의 평가가 거의 없는 것으로 나타났다. 따라서 현재 시스템의 현황조사와 영향예측 및 상응하는 저감대책에 생물다양성 이슈들을 고려하도록 개선할 필요가 있다.

The goal of this essay is to examine metaphors for mathematics and to discuss philosophical problems related to them. Two metaphors for mathematics are well known. One is a tree and the other is a building. The former was proposed by Pasch, and the latter by Hilbert. The difference between these metaphors comes from different philosophies. Pasch's philosophy is a combination of empiricism and deductivism, and Hilbert's is formalism whose final task is to prove the consistency of mathematics. In this essay, I try to combine two metaphors from the standpoint that 'mathematics is a part of the ecosystem of science', because each of them is not good enough to reflect the holistic mathematics. In order to understand mathematics holistically, I suggest the criteria of the desirable philosophy of mathematics. The criteria consists of three categories: philosophy, history, and practice. According to the criteria, I argue that it is necessary to pay attention to Pasch's philosophy of mathematics as having more explanatory power than Hilbert's, though formalism is the dominant paradigm of modern mathematics. The reason why Pasch's philosophy is more explanatory is that it contains empirical nature. Modern philosophy of mathematics also tends to emphasize the empirical nature, and the synthesis of forms with contents agrees with the ecological analogy for mathematics.

It is undeniable that IUU Fishing are threatening so many legal fishermen' economic livelihood, negatively impact on conservation and protection of the fishery stock and ecosystem itself. Especially, negative impact of IUU Fishing resulted from the increasing fishery activities on the high seas. The Korea case of Coastal and Off-shore Fisheries, difficulties in conserving and controlling the fishery stock was brought about. Simultaneously, it is the fact that there are so many damage such as the reduction of fish Stock management program's effect, dissatisfaction of legal fishermen, over-exploiting of fish stock. Related with this kind of problem, FAO had adopted "International Plan of Action to Prevent, Deter and Eliminate Illegal, Unreported and Unregulated Fishing(2001)". From this reason, Korea also needs to make actual efforts to prevent IUU Fishing. i.e. each nation should develop Korea action plan by Feb. 2004 and impliment it, report on implementation toward FAO. This Paper will review the definition of the IUU stipulated by "International Plan of Action on Illegal, Unreported and Unregulated Fishing" and study Korea cases of the IUU fishing. Finally, the analysis of Korea's implementation will be done, centering around the contents stated on the International Action Plan. The significance of this paper is to grope the political countermeasures against international movement of the IUU fishing prevention.

Background: The structures and soil factors of Suaeda glauca-Suaeda japonica zonal communities and Phragmites australis-S. japonica zonal communities were studied in salt marshes of west and south coasts of South Korea to provide basic data for coastal wetland conservation and restoration. Results: S. glauca community mean length was 67 m and S. japonica community mean length was 567 m in zonal communities, and P. australis and S. japonica community mean length were 57 m and 191 m in zonal communities. Regarding the electrical conductivity, sodium content, and clay contents in Upnae-ri, Shinan-gun, there were significant differences among zonal communities at significance level of 0.05 for two-sided t test. However, other factors were not significantly different. Conclusions: The results indicate that multiple factors such as electronic conductivity, total nitrogen level, clay, and sodium might play important roles in the formation of zonal plant communities of salt marshes.

Ecosystems in the Keweenaw Peninsula region of Lake Superior, USA, were disturbed by over 500 million tons of copper-rich mine tailings during the period 1850-1968. Metals leaching from these mine residues have had dramatic effects on the ecosystems. Vast acreages of exposed tailings that are over 100 years old remain unvegetated because of the combination of metal toxicity, absence of nutrients, and temperature and water stress. Therefore, it is important to characterize and fractionate solid copper phases for assessing labile forms of copper in soils and sediments contaminated by the mining wastes. X-ray diffraction analyses indicate that calcite, quartz, hematite, orthoclase, and sanidine minerals are present as major minerals, whereas cuprite,tenorite, malachite, and chalcopyrite might be present as copper minerals in the mining wastes. Sequential extraction technique revealed that carbonate and oxide fractions were the largest pools of copper (ca. 50-80%) in lakeshore and wetland stamp sands whereas the organic matter fraction was the largest reservoir (ca. 32%) in the lake sediments. The concentrations of iron and copper were inversely correlated in the oxide fraction suggesting that copper may occur as a surface coating on iron oxides. As particle size and water contents decrease, the percent of the copper bound to the labile carbonate fraction increases.

In recent years, ubiquitous and pervasive scenarios have emerged as a complex ecosystem where differentiated software/hardware components interoperate wirelessly and seamlessly. The goal is to enable users to continuously access services and contents, and to always get the best out of their current environment and available resources. In such dynamic and flexible scenarios, the need emerges for flexible and general solutions for continuous runtime self-reconfiguration and self-optimization of ubiquitous support software systems. This paper proposes a fully reconfigurable middleware approach that aims at reconfiguring complex software systems made up of heterogeneous off-the-shelf components from both functional and non-functional perspectives. Our middleware can also extend already existing and non-reconfigurable middleware/applications in an easy and flexible way, with no need to re-design them. The proposed design principles have been practically applied to the implementation of a runtime self-reconfigurable middleware called Off-The-Shelf Ready To Go (OTS-RTG), implemented on top of iPOJO. The reported experimental results both exhibit a limited overhead and show the wide applicability of the proposed solution to many application scenarios, including complex, industrial, Enterprise Service Bus-based ones.

In order to investigate the antiotoxic effect of red ginseng extract on serum protein of mouse treated with methyl mercury playing a role as toxic contaminant in ecosystem, variations of the serum protein contents, electrophoretic patterns, and blood components were studied. Mice were divided into 3 groups: Control, group I treated only with methyl mercury, and group II treated together with methyl mercury and red ginseng extract. The total serum protein content of the control group was 5.8g/dl and those of groups I and II were slightly decreased as compared with the control. The control group showed 11 serum protein fractions and groups I and II showed 10 fractions except prealbumin. The amounts of albumin, ${\alpha}_1-$, ${\alpha}_2-$ globulin fractions were decreased and those $\beta$-, $\gamma$-globulin fractions were increased in groups I and II. The amount of each serum protein fraction in group II showed approximately the same level as the control. The hematocrit value and the number of white blood cells of groups I and II were increased, whereas the number of red blood cells showed the decrease as compared with the control.
