일제 36년이 강압통치를 종식시킨 1945년 8월 15일의 해방이 우리에게 가져다 준 가장 큰 선물은 '문화의 광복'이었다. 38선을 기점으로 남북이 분할되고, 남북지역 각각에 미군과 소련군이 진주하는 바람에 주권과 영토의 회복은 반쪽짜리일 수밖에 없었던 데 반해 문화의 광복만큼은 비교적 온전하게 이루어질 수 있었다. 그런 점에서, 1948년 대한민국 정부수립 이전까지 이른바 해방공간은 문화에 관한 한 백가쟁명의 시대였다고 해도 결코 과언이 아니다. 질서와 체계를 추스릴 만한 시간적 여유가 없었던 탓에 한편으로 혼란상을 빚은 것도 사실이지만, 그마저 활기의 또다른 표현으로 해석될 만큼 문화의 광복은 대단한 활기를 띠고 진행됐다. 그리고 그것을 주도한 것이 바로 출판이었다.

역사적으로 우리나라의 전통건축은 중국건축과 밀접한 관계를 지니고 있다. 그래서 중국이 자본주의 경제체제를 수용하면서 개방되자마자 중국건축에 관심을 가지고 있던 많은 사람들이 중국을 방문하게 되었다. 그리고 여러 사람들에 의해 중국건축에 대한 소개가 이루어졌다. 그러나 중국은 워낙 방대한 영토를 지니고 있고, 아직은 중국을 여행하는데 교통이나 안전 등 많은 문제가 있어서 국내에 소개된 중국건축은 빙산의 일각에 불과하다고 할 수 있다. 필자는 지난해 9월 28일부터 10월 25일까지 산서성을 중심으로 한 중국의 일부를 답사한 바 있다. 이번 답사 지역 중에는 기왕에 국내에 잘 알려진 곳도 있고 그렇지 않은 곳도 있다. 이번 기회에 그 답사내용을 사진과 평면 스케치를 곁들어 소개하고자 한다. 중국건축에 대한 이해와 연구에 조금이나마 도움이 되었으면 한다.

As the depletion of land resources, the attention about marine resources has been focused on. Neighboring countries such as Japan and China to expand their marine territory invest more governmental money. The exact territorial sea baselines can be the scientific data which cad resolve the dispute between the neighboring countries. So, those territorial sea baselines should be maintained systematically and continuously. Because territorial sea baselines surveyed 10 years ago without updating, the review may be needed. In this study, we compared 2009 year surveying results with past territorial sea baselines results for reviews. As a results, Jeju Island represents a large difference. So, the outputs of territorial sea baselines around Jeju Island should be readjusted. Through this study, the ongoing maintenance of the territorial sea baselines is required. The continuing interest in the maritime boundary, as well as defend in terms of protection for undersea resources are needed.

The main research question of this paper is as follows: How can broadcasting both cause the crisis in democratic participation and yet also offer the solution? The contradiction in broadcast localism has never been adequately resolved in spite of regulation at all in practice, in that localism simply cannot account for the diversity of modern life and for the external forces that incorporate local communities into much larger economic and communications network. The concept of locality in local television, however, has been multiplied and enlarged in order to adjust to "time-space compression". Recently the local television have been "interface" combining and negotiating the globalization of media market and the decentralization of political power, the economies of scale and the activation of local democracy, consequently aiming at the horizontal-cooperative network instead of old vertical-dependent one.

Since, in 1970, diatoms and diatom indices was first used in measuring quality of streams and rivers at the Seine Water Agency in France, five other water agencies began to show interests since 1990. In 1994, associated with CEMAGREF (Centre National du Machinisme Agricole du Genie Rural et des Eaux et des Forets : environmental science and expertise for the sustainable management of land and water), the six French Water Agencies (Seine, Rhone-Mediterranee-Corse, Artois- Picardie, Loire-Bretagne, Rhin-Meuse and Adour-Garonne) developed a practical diatom index, which is liable to be used routinely in the territorial streams and rivers of whole France, and which is liable to promote and facilitate its use in monitoring water networks. In 1995, the first version of a biological diatom index (IBD) was generated by them. Since then, the software update for IBD calculation and the user's network have led to numerous practical applications in France. Furthermore, the Water Agencies have run applicable programs on the National Basin Network from 1996, and the initial data set of IBD was completed. Re- examination of the complete data set was done at the end of 1998, and the tests on different calculation options of the IBD led to a third version of this index in June,2000 (AFNOR NF T 90-354).

Many countries have interested in islands with their values in nature such as future sustainable resource and new expansion of marine territory. As territorial and cultural assets, these islands have been the source of our national competitiveness and, then, Korean government has initiated island management policy that provides a basis for the development and protection of islands. Consequently, spatial data and database for resource management have been required. In this sense, the purpose of this paper is to investigate the condition and status of various natural resources in Jeju islands. Jeju has 63 islands including 55 uninhabited islands. Then, an Island Information System(IIS) based on geographical information system(GIS) has been proposed. This ISS will provide not only a measure for effective resource management but also systematic services for releasing useful resource information.

China, since the early days, according to their ideology, neighboring countries and their citizens were under their sphere of power. This means that only the Hanzu are real native Chinese and the other minor ethics groups are technically immigrants. The People's republic of china, part of the chinese communist party, has had rapid economic growth after Deng Xioping took over and implemented various expansionist policies and reforms, opening china to the world. Internally, the minority ethnic groups were forcibly relocated to specific regions, prohibited from using their native languages, and their culture was absorbed or incorporated into the Hanzu culture in an attempt to internally suppress or erase them. Externally, various projects such as the 'Xia-Shang-Zhou Chronology Project', 'Origins of Chinese Civilization Project', 'Northeast Project', 'Northwest Project', and the 'Southwest Project' were implemented to spread their culture and history to neighboring countries in an attempt to expand their territory. In addition, as capitalism spreads throughout china through reforms and its expansion, it has pioneered the one belt one road aiming to secure as safe transit and raw materials, expand their military facilities, and expand their export market. By doing so, China is infringing on other countries' politics, economy, and borders, and as a result there is a need for Korea to also reexamine its policies in all fields related to china such as politics, economy, history, and culture.

The purpose of this paper was to propose a method for improving the performance of the open-loop control of single-phase permanent magnet synchronous motor (SP-PMSM), based on a square wave voltage injection. Generally, the SP-PMSM driving systems cmprise a full-bridge inverter and asymmetric air-gap structure of magnetic circuit, because a zero torque occurs on the symmetrical air-gap. As a result, it cannot be started at a specific rotor position. Thus, it is possible to cause the start-up failure at an open-loop control for sensorless operation of SP-PMSM. In this paper, the method with square wave voltage injection considering the nonlinearity of the inverter is presented to resolve the problem. The effectiveness of the proposed algorithm is verified through several experiments.

China's new Maritime Policy Law (MPL) purports to regulate the duties of China's maritime police agencies, including the China Coast Guard, and safeguard China's sovereignty, security, and rights and interest. The MPL has potentially far-reaching application, as China claims extensive maritime areas off its mainland and in the South China Sea. This expansive application of maritime law enforcement jurisdiction is problematic given that most of China's maritime claims are inconsistent with international law. To the extent that the MPL purports to assert jurisdiction over foreign flagged vessels in disputed areas or on the high seas, it contravenes international law. Numerous provisions of the MPL regarding the use of force are also inconsistent with international rules and standards governing the use of maritime law enforcement jurisdiction, as well as the UN Charter's prohibition on the threat or use of force against the territorial integrity or political independence of any state. China could use the MPL as a subterfuge to advance its illegal territorial and maritime claims in the South and East China Seas and interfere with coastal State resource rights in their respective exclusive economic zone.

공용어로 스페인어를 사용하며 통화는 미국 달러를 사용하는 에콰도르 공화국(Republic del Ecuador)은 남아메리카 북서부에 위치한 중소국가다. 미주 기구(OAS), 석유수출국 기구(OPEC), 남아메리카 국가 연합(UNASUR), 라틴어 연합(Latin Union) 등에 가입되어 있고 활발한 대외활동을 펼치고 있다. 그럼에도 불구하고 사실 에콰도르의 대외 위상은 그리 높지 않다. 생태학적으로 중요한 갈라파고스 제도가 에콰도르의 영토라는 사실을 아는 사람이 극히 적을 정도로 에콰도르는 우리에게 먼 나라다. 그러나 최근 에콰도르는 항공우주분야에서 급격한 두각을 나타내고 있다. 2007년 11월 설립된 에콰도르 민간 우주기구(La Agencia Espacial Civil Ecuatoriana)를 중심으로 우주개발에 적극 뛰어들고 있기 때문이다. 에콰도르 최초의 우주인을 배출하고 주요 항공우주 선진국과 협력을 강화해 나가고 있는 에콰도르 민간 우주기구의 활약을 소개한다.
