        해상집회,시위에 대한 연구

        이희훈 ( Hie Houn Lee ) 단국대학교 법학연구소 2010 법학논총 Vol.34 No.1

        Considering that participants in assembly and demonstration on the sea can manifest their own personality, supplement democratic justification under representative democracy and protect the minority by opening assembly or demonstration and that an effect of assembly or demonstration against ludicrous statements related to Dokdo will be maximized when opened rather on the sea than on land, the place on the sea is pertinent to the protected area of freedom of assembly. On the other hand, it is valid to apply law on assembly and demonstration to peaceful assembly and demonstration on the sea. For, the place on the sea is pertinent to `where general people can pass through freely` out of Article 2, Clause 2 of law on assembly and demonstration since most of participants in assembly and demonstration on the sea don`t use large-scale ships besides hybrid vessel. And it is pertinent to `Behaviors which have an effect on diverse unspecific people`s opinions or control them by showing power and force to others` out of Article 2, Clause 2 of law on assembly and demonstration since, if participants in assembly and demonstration on the sea argue their common opinions by moving a lot of ships on the sea at once, it will have an effect on diverse unspecific people. Therefore, it is reasonable to apply assembly and demonstration on the sea to law on assembly and demonstration in the present. However, it is invalid to restrict or regulate assembly and demonstration on the sea by applying sea related laws such as public order in open ports act and sea traffic safety act enacted to protect sea traffic since it restricts freedom of assembly by sea related laws with different purpose of legislation, which restricts natural rights in constitution which is freedom of assembly without clearly stated ground law.

        海澄 개항과 새로운 교역망의 형성

        채경수 명청사학회 2020 명청사연구 Vol.0 No.54

        This article examined the development process of a brand-new oversea commerce network centered around a harbor named Hai-Cheng海澄, which took the official open port of the Ming empire after 1567. This article Significantly dealt with the connection of Hai-Cheng海澄 with Manila, which was the Spain empire's colonial stronghold of the Eastern Asian Seas at that time. For the Ming empire, the open of Hai-Cheng海澄 port was a measure to secure coastal stability. Many pro-trade officials criticized that the indiscriminative sea-ban policy in the late Jia-Jing嘉靖 era had threatened littoral people's livelihood, it made them conspire with wokou倭寇 and pirates. They claimed that the license trade system would be the most efficient policy for coastal security. Since the early stage of the open-sea policy,the Ming court's main interest was on the coastal area's long-term stability, rather than the area's economic vitalization or tax revenue. The Hai-Cheng海澄 oversea trade started to be supervised by systematic license regulations since 1575. At the time, the Spain empire buckled down to an inroad into Eastern-Asian seas. It chose Manila as a colonial stronghold in this area. Not long after, a very prosperous trade network, which was second only to the Macao-Nagasaki route, was developed between Hai-Cheng海澄 and Manila. This trade network developed relying on high profitability, driven by a mutual preference for each other’s goods – Chinese silk and American silver. Further, the stable diplomatic relationship between those empires was a solid foundation for maintaining this trade network. The Hai-Cheng海澄 – Manila trade network was in a crisis of trade break at least twice. The one was the sea-ban of the Ming court in 1593, which was caused by the Korea-Japan War broken out in the previous year. The other was the massacre of the Chinese in Manila by the Spain authority that occurred in 1603. Although both cases could be recognized as severe security threats for the Ming court, neither were led to a long-term commerce disconnection. The Fujianese coastal merchants, who were in oversea trade business, succeeded in fending off or minimizing the sea-bans by lobbying their local governments. The local officials, who tried to persuade the central government to withdraw the sea-ban for protecting the oversea trade merchants' profit, presented a critical argument that open-sea is a better policy than a sea-ban for coastal security. Due to conceding its validity, the Ming court maintained the license trade system consistently, despite security crises. The Hai-Cheng海澄 – Manila trade network kept flourishing by balancing the Ming's security interest and the merchant's economic interest. The Spain authority in Manila also played an essential role in this trade network due to maintaining a non-hostile mood with the Ming built up during initial contact. The massacre of the Chinese in 1603 could escalate into a severe conflict between these empires. However, both powers defused the situation quickly by a swift diplomatic negotiation. The Hai-Cheng海澄 – Manila trade network kept functioning as if nothing had happened.

        일본 니가타[新瀉]항을 통해 본 ‘제국’의 환동해 교통망

        김윤미 동북아시아문화학회 2019 동북아 문화연구 Vol.1 No.60

        The Northeast Asian sea surrounding South Korea is being discussed in terms of politics, economy and military beyond the geomorphological area. Pan East Sea, where South Korea, North Korea, Japan, Russia and China form the network, initiated from the planning of the economic bloc, but it currently refers to the neighboring countries and the sea area surrounding the East Sea in general. The point that connects the sea area is the port. The marine and land traffic networks stretch out in line with the port as a core. The thesis intends to examine, in overall, the individual subjects from the precedent research. The traffic networks centered on ports, railways and sea lanes are only effective if abundant electricity and port hinterland are formed. In other words, it goes through the process of building power plants to supply electricity, securing a large tract of land to construct the hinterland, and creating the infrastructure such as labor and administration to build a port city. Of course, the budget is mostly funded by the government. This relationship will be studied through the case of Niigata in Japan that played the major role as the East Sea’s traffic network. The Niigata Port rapidly grew along with the expansion of Japanese imperialism in the 1930s and 1940s. The Dalian Port was the central route to connect Japan and Manchuria until 1920, but Japan, which founded Manchukuo in 1932, tried to make the shortest East Sea route between Japan and Manchuria. At that time, Japan observed 新瀉港·伏木港·敦賀港 in Japan and Cheongjin Port·Najin Port·Woonggi Port in the northern part of Joseon. After designating the subsidized line, Japan began expanding port facilities in the Niigata Port and enlarging the city. This was the outcome of traffic network policy for Pan East Sea of imperial Japan.

      • Spatio-temporal patterns of Secchi depth in the waters around the Korean Peninsula using MODIS data

        Kim, S.H.,Yang, C.S.,Ouchi, K. Academic Press in association with the Estuarine a 2015 Estuarine, coastal and shelf science Vol.164 No.-

        Secchi depth (Z<SUB>SD</SUB>) is an important variable for the measurements of long-term changes in the water transparency of oceanic and coastal ecosystems. This study aims at analyzing the spatial and temporal variations of MODIS-derived Z<SUB>SD</SUB> time-series during 2000-2012 in the adjacent waters around the Korean Peninsula, highlighting the environmental variables affecting variations of Z<SUB>SD</SUB> with various water depths. A semi-analytical model is used to estimate the diffuse attenuation and beam attenuation coefficients from satellite data, and the reciprocal of the sum of the two parameters was compared with the in-situ Z<SUB>SD</SUB> to retrieve a satellite-based Z<SUB>SD</SUB>. In general, the open sea waters in the East Sea/Sea of Japan have higher Z<SUB>SD</SUB> than the coastal waters in the Yellow Sea. From the analyses, distinct seasonality was found in the monthly average images of MODIS-derived Z<SUB>SD</SUB> data and spatio-temporal patterns of the Empirical Orthogonal Function (EOF), and the seasonal variation of Z<SUB>SD</SUB> was associated with the variability in the ocean-atmosphere dynamics including the wind and current as well as chlorophyll-a. In the coastal and shallow waters in the Yellow Sea, prevailing north westerly winds produce turbid waters in winter, while in deep waters in the East Sea/Sea of Japan, water transparency is reduced by the spring bloom of chlorophyll-a. There are two clear Z<SUB>SD</SUB> peaks within a year in the East China Sea associated with the Kuroshio Current. A similar trend was observed in the South Sea, but less clear due to complex mixing processes of currents and effects of wind. Correlation of in-situ Z<SUB>SD</SUB> with water depth was also found suggesting the need for consideration in analyzing satellite Z<SUB>SD</SUB> data.

        Geometry and kinematics of the Ocheon Fault System along the boundary between the Miocene Pohang and Janggi basins, SE Korea, and its tectonic implications

        천영범,손문,송철우,김종선,손영관 한국지질과학협의회 2012 Geosciences Journal Vol.16 No.3

        Detailed geological mapping and observations of various structural elements were made in order to determine the geometry and kinematics of the Ocheon Fault System (OFS) along the boundary between the Early Miocene Janggi and the Middle Miocene Pohang basins, SE Korea, and to reveal its roles on the basin evolutions. The OFS is a NE-trending relayed fault system composed of a number of NE or NNE-trending normal-slip and sinistral-normal oblique-slip faults, and has a scissor fault geometry decreasing in vertical offset southwestward. The constituent faults created independent grabens or half-grabens on the hanging-walls for the deposition of the Early or Middle Miocene strata. The OFS was initially the northwestern border fault of the Janggi Basin which acted as normal faults by the WNW-ESE tensional stress associated with the NNW-directed dextral simple shear caused by the East Sea opening. Afterwards, it experienced clockwise rotation with change of slip sense from normal-slip to sinistral-normal oblique-slip in response to the progressive dextral simple shear. At about 17 Ma, the shear stress propagating westward was released rapidly by the dextral strike-slip faulting of the NNW-trending Yeonil Tectonic Line (YTL) and the normal faulting of the NNE-trending western border faults of the Pohang Basin. At that time, the depocenter suddenly migrated northward and the depositional environment also changed rapidly from terrestrial to marine due to dramatic subsidence of the Pohang Basin. The Pohang Basin is interpreted to be a pull-apart basin extended at releasing bend/overstep between two PDZs (Principal Displacement Zones), i.e., the YTL and probably the East Korea Fault. The OFS was also reactivated as the eastern border faults of the Pohang Basin. In contrast to the western border faults, the OFS was rotated clockwise and could not be linked with the YTL because of its scissor fault geometry. Our results suggest that the NNW-trending regional dextral shear stress persisted for a considerable period of time in SE Korea during the East Sea opening, supporting the pull-apart opening of the East Sea rather than the fan-shaped opening. Most of the previous studies advocating the pull-apart opening emphasize the role of the NNE-trending strike-slip faults, like the Yangsan fault and OFS, as PDZs. In contrast, this study suggests that the NNE-trending faults in SE Korea acted as major normal faults at releasing bends or stepovers in the NNW-trending dextral fault system during the East Sea opening

        남극 로스해 보퍼트 섬 인근에서고해양 환경변화 해석을 위한 규조 연구

        박영숙,이재일,유규철,김성한,이민경 한국지구과학회 2025 한국지구과학회지 Vol.46 No.2

        남극 로스해 보퍼트 섬 인근에서 획득한 코어퇴적물로부터 고환경변화를 복원하기위해 규조를 분석하였다. RS19-GC09코어로부터 총 27속 5 7종의 규조를 감정하였으며, 규조의 생산성을 나타내는 개체수 농도는 0.01-28.75×107/g범위에 해당하였다. 규조의 수직분포 변화를 토대로 4개의 군집대를 설정하였다. 해빙종(Sea-ice species: TC);Fragilariopsis curta, Fragilariopsis linearis, Fragilariopsis obliquecostata, Fragilariopsis ritscheri와 Pseudo-nitzschiaturgiduloides)와 공해종(Open water species: TW); Fragilariopsis kerguelensis, Thalassiosira lentiginosa, Thalassiosiraantarctica와 Rhizosolenia styliformis)의 산출을 대자율(Magnetic Susceptibility; MS)과 총유기탄소(Total organic carbone;TOC)값과 비교하였다. 군집대 I은 낮은 TC, TW와 TOC를 보이고, 반대로 높은 MS 곡선을 나타내어 두꺼운 해빙 또는빙붕 하부 환경에 해당하였다. 군집대 II는 높은 TC, 증가하는 TW와 TOC, 반대로 낮아지는 대자율을 나타내어 계절적인 해빙의 지속기간이 길고 분포가 확장되었다. 군집대 III은 감소된 TC, 높은 TW과 TOC, 가장 낮은 곡선의 MS를 보이는 구간으로 공해환경의 지속기간이 길었던 시기이다. 군집대 IV에서는 TC의 증가와 반대로 TW가 감소 하며, TOC값은 유의미한 변화를 보이지 않고, MS가 약간 상승하는 시기로서 다시 해빙의 지속기간이 길어 졌음을 나타낸다. Diatoms were analyzed to determine paleoenvironmental changes in core sediments obtained near Beaufort Islandin the Ross Sea. A total of 57 species belonging to 27 genera were identified from the RS19-GC09, and the number ofdiatom valve abundance ranged from 0.01 to 28.75×107/g. Four assemblage zones were established based on the verticaldistribution curves of diatom. The occurrence of sea ice species (TC; Fragilariopsis curta, F. linearis, F. obliquecostata, F. ritscheri, and Pseudo-nitzschia turgiduloides) and open water species (TW; F. kerguelensis, Thalassiosira lentiginosa, T. antarctica, and Rhizosolenia styliformis) was compared with magnetic susceptibility (MS) and total organic carbon (TOC)values. Diatom assemblage zone I showed a high MS curve, contrary to low TC, TW, and TOC corresponding to heavysea-ice or sub-ice shelf conditions. Diatom assemblage zone II showed high TC, increasing TW and TOC values, andconversely, decreasing MS values indicating a long duration of seasonal sea-ice and an expanded distribution. Diatomassemblage zone III showed decreased TC, high TW and TOC, and the lowest MS curve, indicating a long period in anopen water environment. Diatom assemblage zone IV showed a period of decreasing TW, conversely increasing TC, nonoticeable change in TOC, and slightly increasing MS, again indicating a period of long sea-ice duration.

        19세기 미국의 해군력 확장과 태평양 시대의 개막

        이상호 ( Lee Sang-ho ) 한국미국사학회 2018 미국사연구 Vol.48 No.-

        The United States of America joined the struggle for colonies abroad later than other Western Powers. One of the reasons was the weak naval power. The expansionists in USA in 1880s deployed the movement to strengthen the naval force and such movement was more activated after the publication of ‘Influence of sea power upon history 1660-1783’ by Alfred T Mahan. It was since 1896 when Mr. William McKinley was elected to the President of USA that the foreign policy was officially implemented in such flood tide of expansionism. The MaKinley administration put the top priority on making USA leading the global market in its foreign policy. The battle againt Spain in 1908 confirmed the need to strengthen the naval power. Meanwhile, the modernization of USA Navy was accelerated by Mr. Benjamin F. Tracy who was the Secretary of the Navy in the administration of President Benjamin Harrison in 1889, and reached an apex by Mr. Theodore Roosevelt who was the Assistant Secretary of the Navy during the McKinley administration and became the President of USA later. In the process deploying the strong expansionist policy for foreign policy and strengthening the naval power, deliberation on Asia in the foreign policy of USA was started from the breakup of China. The Boxer Rebellion broke out in 1900 and the European powers suppressed and defeated it. Then, the formal treaty was executed in Sep. 1901. The kernel of the treaty was the permit on military presence of the Western Powers and compensation. While the Boxer Rebellion was in progress, Mr. John Hey, the Secretary of the State, notified the declaration of open-door to the World Powers twice. The early open-door policy aimed to protect and promote the commercial rights and interests of the USA in China by strictly dividing the sphere of power and influence of each World Power and so inducing World Powers to restrain each other. Furthermore, the second open-door policy tried to restore the Chinese government as solving the internal affairs and accordingly, secure the profits of the World Power. In conclusion, the USA embodied the policy against China through the open-door policy and successfully built the foothold as the Pacific Empire by unilaterally pushing on its policy to the Western Powers. The successful entrance of USA to the Pacific region through such diplomacy of power became the basis for rapidly strengthening the naval power of the USA.

        Benthic Meiofaunal Composition and Community Structure in the Sethukuda Mangrove Area and Adjacent Open Sea, East Coast of India

        Balasubramanaian Thilagavathi,Bandana Das,Ayyappan Saravanakumar,Kuzhanthaivel Raja 한국해양과학기술원 2011 Ocean science journal Vol.46 No.2

        The ecological aspects of meiofaunal communities in the Muthupettai mangrove forest, East coast of India, has not been investigated in the last two decades. Surface water temperature ranged from 23.5 ^oC to 31.8 ^oC. Salinity varied from 24 to 34 ppt, while water pH fluctuated from 7.4 to 8.3. Dissolved oxygen concentration ranged from 3.86 to 5.33 mg/l. Meiofauna analysis in this study identified a total of 106 species from the mangrove and adjacent open sea area of Sethukuda. Among these, 56 species of foraminiferans, 20 species of nematodes, 7 species of harpacticoid copepods, 4 species of ostrocodes, and 2 species of rotifers were identified. Furthermore, a single species was identified from the following groups: ciliophora, cnidaria, gnathostomulida, insecta, propulida, bryozoa and polychaete larvae. Meiofaunal density varied between 12029 to 23493 individuals 10 cm/m2. The diversity index ranged from 3.515 to 3.680, species richness index varied from 6.384 to 8.497, and evenness index varied from 0.839 to 0876 in the mangrove area and adjacent open sea.
