  • 본 연구는 생태관광, 글로벌 교육의 개념을 토대로 다소 연구 성과가 미흡한 오세아니아지역에 대하여 생태관광자원의 지리적 특징을 파악하고 호주 Cairns 지역을 사례로 현지답사를 한 후, 생태자원의 교육적 활용에 대해 고찰하였다. 답사지역은 Great Barrier Reef의 Green 섬, Queensland주 열대우림의 Barron Gorge 국립공원 삼림탐방프로그램, Eairns 근교 호주나비보호구역, Tjabutkai 원주민 문화공원을 선정하여 현지답사를 수행하였다. 사례연구를 통해 의미있는 글로벌 교육적 활용방안을 살펴보면 Green섬에서는 특수 제작된 수중관측소와 바닥이 유리로 된 배 등을 도입하여 해양생태를 효과적으로 보존하면서 탐사하도록 했고, 잘 디자인된 탐방로와 탐방시간 안내판 그리고 친절하게 생태교육을 담당하는 공원관리원이 주재하는 삼림탐방프로그램이 마련되었으며, 옛 산업열차를 보완하여 관광용열차로 재활용한 것은 환경보호를 위한 좋은 본보기였다. 나비보호구역에서는 여러 언어를 지원하는 안내체계를 갖추고 전문가와 함께하는 해설프로그램을 마련하였으며, 전 세계의 방문객들에게 원주민의 생활을 체험할 수 있도록 프로그램을 고안하여 자신의 문화를 널리 알리고, 방문객에게도 교육적인 효과를 충족시킬 수 있도록 하였다.

  • International law provides for fundamental navigational rights called the right of transit passage in international straits as defined by UNCLOS. However, the Australian government published Marine Notice 8/2006 and the associated Part 54 of Australian Marine Orders which requires ships transiting the Torres Strait to engage the services of a pilot and imposes significant penalties for non-compliance on the basis of the IMO MEPC 133(53) which is just a resolution as a recommendation. This paper aims to study legal aspects in UNCLOS on the pilotage in the Torres Strait following the extension of the Great Barrier Reef PSSA neighbouring Australia.

  • When tsunami waves propagate across open ocean they are steered by Coriolis force and refraction due to gentle gradients in the bathymetry on scales longer than the wavelength. When the wave encounters steep gradients at the edges of continental shelves and at the coast, the wave becomes non-linear and conservation of momentum produces squirts of surface current at the head of submerged canyons and in coastal bays. HF coastal ocean radar is well-conditioned to observe the current bursts at the edge of the continental shelf and give a warning of 40 minutes to 2 hours when the shelf is 50-200km wide. The period of tsunami waves is invariant over changes in bathymetry and is in the range 2-30 minutes. Wavelengths for tsunamis (in 500-3000 m depth) are in the range 8.5 to over 200 km and on a shelf where the depth is about 50 m (as in the Great Barrier Reef) the wavelengths are in the range 2.5 - 30 km. It is shown that the phased array HF ocean surface radar being deployed in the Great Barrier Reef (GBR) and operating in a routine way for mapping surface currents, can resolve surface current squirts from tsunamis in the wave period range 20-30 minutes and in the wavelength range greater than about 6 km. There is a trade-off between resolution of surface current speed and time resolution. If the radar is actively managed with automatic intervention during a tsunami alert period (triggered from the global seismic network) then it is estimated that the time resolution of the GBR radar may be reduced to about 2 minutes, which corresponds to a capability to detect tsunamis at the shelf edge in the period range 5-30 minutes. It is estimated that the lower limit of squirt velocity detection at the shelf edge would correspond to a tsunami with water elevation of less than 5 cm in the open ocean. This means that the GBR HF radar is well-conditioned for use as a monitor of small and medium scale tsunamis, and has the potential to contribute to the understanding of tsunami genesis research.

  • While much in the field of public management has emphasized the importance of nonprofit advocacy activities in policy and decision-making procedures, few have considered the relevance and impact of leading actors on structuring diverse patterns of information sharing and communication through social media. Building nonprofit advocacy is a complicated process for a single organization to undertake, but social media applications such as Facebook and Twitter have facilitated nonprofit organizations and stakeholders to effectively share information and communicate with each other for identifying their mission as it relates to environmental issues. By analyzing the Australian Marine Conservation Society's (AMCS) Twitter network data from the period 1 April to 20 April, 2013, this research discovered diverse patterns in nonprofit advocacy by leading actors in building advocacy. Based on the webometrics approach, analysis results show that nonprofit advocacy through social media is structured by dynamic information flows and intercommunications among participants and followers of the AMCS. Also, the findings indicate that the news media and international and domestic nonprofit organizations have a leading role in building nonprofit advocacy by clustering with their followers.
