P2E(Play-to-Earn)게임은 기존의 게임과 달리 게임을 통해 아이템 NFT, 가상자산(토큰) 획득으로 게임 이용자가 수익을 얻을 수 있는 게임의 한 종류다.1) 2023년도 국내에서 P2E게임 관련 판례가 확정되었고, 이에 따라 해외와 달리 국내에서 P2E게임은 전면 금지되고 있다. 기존 선행연구 에서 지속적으로 비판받아왔듯이, P2E게임에서 가상자산이 활용된다고 하 여, 가상자산의 사행적 측면을 혼재시켜, P2E게임을 사행성 게임물로 곧장 판단하는 것은 오도다. P2E게임 상에서 아이템의 NFT화와 게임 내 토큰 활용 과정을 면밀히 재검토한 결과, 선행연구에서 밝히고 있는 법리상의 문 제점에 더하여, P2E게임의 우연성 해소 가능성, 사행성 게임물과 P2E게임 의 본질적 차이(기대값), P2E게임과 가상자산의 분리 등의 새로운 문제점 을 발견할 수 있었다. 이에 따라, 본고에서는 국내 P2E 게임의 전면 금지의 배경이 된 최근 2 개의 판례를 비판적 검토함과 동시에 P2E게임에 대한 국내 선행 연구를 정리한 뒤, 우리나라 가상자산이용자보호법과 그 토대가 되는 EU의 MiCA 법, 그리고 프랑스 국내법인 SREN법을 살펴 우리나라에서 향후 P2E게임 이 허용될 가능성을 검토하고 그 방향성에 대한 논의를 담았다.

Global climate change is significant issue in marine ecosystem and fishery market. According to rising of both seawater temperature and sea-level, global fishery environment and marine ecosystem are changing drastically. Moreover, over-exploitation in fishery areas is the most important issue in the marine ecosystem conservation. In analysis and statistics of global network, major fish populations are decreasing very fastly, but fish catch are increasing annually. It means balance between product and consume is not appropriate in the global market. China as emerging new fish consumer in the world is strongly developing fishery industry and technology. In this paper, I try to review a relationship between marine ecosystem and climate change in global scale according to references. I also suggested possibility of sustainable global fishery in changing marine ecosystem by analysis of some related reports of international global fishery.

To decide on the designation of a tidal-flat Provincial Park, a study area was defined in line with domestic and international case studies of Provincial Parks. A survey on landscape, geology, biota, and cultural resources was conducted in four tidal-flat areas including Bigeum-myeon and Docho-myeon, which are part of the UNESCO Biosphere Reserve in Shinan, Jeollanam-do. To identify areas most suitable to be designated as Provincial Park, a PSR evaluation process was adopted. This has resulted in the selection of the ‘Palgupo’ area surrounding Bigeum, Docho, Haui, Shinui, Jaeun, Amtae, Palgeum, Anjwa and Jangsan. Also the tidal-flat areas at Aphae-myeon, which are ecologically linked with the Jeungdo Tidal-flat Provincial Park, were included. The selected areas resulting from this study will meet various characteristics of tidal-flat ecosystems including naturalness, ecological network, rarity and eco-cultural diversity. After the tidal-flat Provincial Park has been specified, there is a need to perform a long-term sustainable management plan.

Nickel oxide was doped with a wide range of concentrations (mol%) of Aluminum (Al) by solvothermal synthesis;single-phased nano powder of nickel oxide was generated after calcination at 900oC. When the concentration of Al dopant wasincreased, the reduced intensity was confirmed through XRD analysis. Lattice parameters of the synthesized NiO powder weredecreased after treatment of the dopant; parameters were increased when the concentration of Al was over the doping limit(5mol% Al). The binding energy of Ni2+ was chemically shifted to Ni3+ by doping Al3+ ion, as confirmed by the XPS analysis.The tilted structure of the synthesized NiO with 5mol% Al dopant and the polycrystalline structure of the Ni0.75Al0.25O wereobserved by HR-TEM analysis. The electrical conductivity of the newly synthesized NiO was highly improved by Al dopingin the conductivity test. The electrical conductivity values of the commercial NiO and the synthesized NiO with 5mol% Aldopant (Ni0.95Al0.05O) were 1,400s/cm and 2,230s/cm at 750oC, respectively. However, the electrical conductivity of thesynthesized NiO with 10mol% Al dopant (Ni0.9Al0.1O) decreased due to the scattering of free-electrons caused by the largenumber of impurity atoms; the electrical conductivity of Ni0.9Al0.1O was 545s/cm at 750oC.

Natural resource of the island and coastal regions is one of the most important element of ecological network system in Korea. Currently, there is trend that natural and biological resources such as fishing and tidal wetland have been used to local economic activation in island and coastal regions. According to the 5-days work in a week, island and coastal regions become important amenity resource of citizen's recreation area. Korea is peninsula surrounded by maritime. Especially, South and West Sea surrounded by many islands and tidal flat wetlands are emerging marine ecosystem and seascape in the world. Natural resource is limited, so we have to sustain those resource to current tourism. In this study, I would like to suggest that importance of cultural resource as well as natural resource for 'eco-cultural tourism' in order to keep both biological diversity and cultural diversity as amenity resource for future island economic activation in Korea.
