Historically, commerce was a significant factor in the proliferation and development of Buddhism, which is especially manifest in the cult of the bodhisattva Avalokiteśvara. Iconographic and textual evidence testifies that maritime trade on the Indian Ocean played a fundamental role in the formation of Avalokiteśvara worship. The sea was also a major conduit through which elements of the Avalokiteśvara faith were transmitted from India through China to Korea and Japan, the easternmost ends of the Silk Road. These elements include Avalokiteśvara's role as a maritime savior, oceanic symbolism, and the concept of the bodhisattva's worldly abode, Potalaka. Cultic sites dedicated to maritime safety were established at important transport hubs in East Asia. Due to China's strategic location on the Silk Road, as well as its cultural influence, the most important cultic sites were founded in China, first on the Shandong Peninsula, then in the southern Jiangnan region, in present-day Zhejiang Province. Especially notable is the role that Korean seafarers played in this process by assisting monks in search of the Dharma, establishing temples, and transmitting religious beliefs across the ocean. The present study focuses on the role that maritime figures played in the cultural exchanges between Korea, China, and Japan examined through Avalokiteśvara faith. By this, it aims to demonstrate how Korean seafarers inherited and continued the traditional relationship between commerce and Buddhism, while extending the Maritime Silk Road to the "East Asian Mediterranean."

India, Southeast Asia in general, and Siam in particular share a long history of cultural and commercial relations. Located in each other's extended neighbourhood, India and Thailand have a shared maritime boundary in the Andaman Sea. Situated in the strategic position, midway between West Asia on the one hand and East Asia on the other, India and Siam combined played a significant role in the maritime transactions in Asia and beyond. The geographical proximity between India and Siam led to multifaceted maritime interactions and exchanges. Siam was in the Indian sphere of cultural, religious, philosophical, technical, and linguistic influence much before the Common Era. The cultural and mercantile networks between India and Siam are well-attested by archaeological and literary sources. The archaeological findings in Siam and other Southeast Asian countries have revealed the dynamic trade and cultural exchange between India and Southeast Asia since the pre-Common Era. The Takola (modern Takua Pa) area served as a more suitable landing place for Indian merchants and there existed the settlement of the Indian mercantile community. Ligor (Nakhon Si Thammarat), Jaya (Chaiya), Patalung (Phatalung), U Thong, Ban Don Tha Pet, Ban U Taphao, Khao Sam Kaeo, and many other sites in Siam have brought to light a large variety of objects which demonstrate that ancient Siam had close mercantile contact with India as well as the Mediterranean world and China. The paper discusses in detail the cultural and trade links between India and Siam and their impact on the Maritime Silk Road.

The real nature of the west wind in Shelley's Ode to the West Wind is the divine providence which influences all things in this world- that is, whether they are on land, in the sky, or in the sea. The divine providence is the manifestation of something beyond the present and tangibel object. In the first stanza, the real nature of the west wind in this poem is the wild wind, the breath of Autumn's being, the unseen presence, the azure sister of the Spring, a Destroyer, a Preserver, the winged seed, a creator, a philosopher, a poet, Shelley, and the wild spirit moving everywhere. In the second stanza, the real nature of the west wind in this poem is cloud, the angel of rain and lightning, fierce Maenad, the approaching storm, the congregated might, the black rain, the fire, hail, solid atmosphere, the tremendous power of revolutionary change, and the power that influences all things in the sky. In the third stanza, the real nature of the west wind in this poem is the voice that makes the oozy woods which wear the sapless foliage of the Atlantic, and the power makes the blue Mediterranean wake from his summer dream. the fit medium of expression which Shelley's soul was seeking for, Shelley's passion, Shelley's partner, Shelley's co-worker, and a strong presence which influences in the sea. In the fourth stanza, the real nature of the west wind in this poem is the mightest presence, the power, the strength, the free presence, the uncontrollable, the wanderer over heaven, a vision, the tameless, the swift, the proud and the God who can save Shelley form the heavy weight of hours and lift Shelley as a wave a leaf, a cloud. In the fifth stanza, the real nature of the west wind in this poem is the mighty harmony, the fierce Spirit, Shelley's spirit, the impetuous spirit, incanation of this verse, spark, the trumpet of a prophecy, the Providence which can make the Winter depart and call Spring, and the prophet. To conclude, the real nature of the west wind in this poem is Shelley's accumulated insight that he visulize his impulse of revolutionary thought.

To minimize secondary damages from marine environment pollution resulting from marine accidents, International Maritime Organization(IMO) adopted "Guidelines on Places of Refuge(POR) for ships in need of assistance" as Resolution A.949(23) in it is 23rd General Assembly in 2003 and recommends Parties to the Organization designate PoR. This resolution suggests that they establish a "Decision-Making process" so as to provide reasonable PoR when disabled ships request use of PoR. Korea has not been performed introduce a PoR system in the country. Therefore, there is no decision-making process to deal with ships which need PoR. When Korea implements the PoR system in the future, the nation should establish a Decision-Making process to provide reasonable PoR in case ships in need of assistance request for PoR. In order to present what should be considered in the process of establishing a Decision-Making process for PoR in Korea in the future, in this study presents matters which should be considered in the process of founding PoR Decision-Making processes. When Korea tries to conduct POR system so that other countries' PoR Decision-Making process and the relating process of IMO and REMPEC (Regional Marine Pollution Emergency Response Centre for the Mediterranean Sea) were investigated and analyzed. In addition, in times of marine accident in Korea's sea areas, Korea's action manuals for marine accident which regulates management for an accident is analyzed and articles will be presented to be taken into account during establishing final PoR Decision-Making process.

The Hebrew word for silk, meshi, is mentioned in the Bible only once and there is a possibility that the item to which it referred was made of local wild silk. Although Jewish historical sources from the Roman and Byzantine periods mention silk many times, only a few silk textiles have been discovered at a sited dated to the Byzantine period (4^th-7^th centuries CE). The word "silk" occurs in the New Testament, although only once. A turning point in the history of the Negev (Southern Israel) occurred around 400 CE when it underwent a period of prosperity related to the advent of Christianity and pilgrimage, which enabled the purchase of imported silk textiles. The Early Islamic period (7-8th centuries CE) yielded four (out of 310) silk textiles from Nahal 'Omer on the Spice Routes joining Petra, in the Edom Mountains of modern Jordan, and the mercantile outlets on the Mediterranean Sea, notably Gaza and El Arish. The most important silk textile assemblage in the Southern Levant was found near Jericho at Qarantal Cave 38 and dates to the medieval period (9th-13th centuries CE). Linen textiles decorated with silk tapestry originating in Egypt date back to the 10-11th centuries CE. Mulham textiles - silk warp with hidden cotton wefts - were discovered in the medieval fortress on Jazirat Fara'un (Coral Island) in the Red Sea, 14 kilometers south of Elat and today located in Egypt. Mulham is mentioned in literary sources of the ninth century in Iraq and Iran, whence it spread through the Islamic world. The article will present aspects of the origin, transmission, and exchange of these textiles.

연안 해역에서 공간적으로 미세한 생태학적, 생지화학적 변화를 파악하기 위해서는 저해상도의 해색위성보다 Landsat ETM+나 SPOT HRV와 같은 중간 해상도의 육상관측 위성을 이용하는 것이 더 효과적이다. 이 연구에서는 각 밴드의 spectral response curve를 고려하여 Landsat TM/ETM+용 부유퇴적물 농도 추정 알고리즘을 개발하였다. Landsat 영상으로부터 연안 부유퇴적물 알고리즘을 향상시키기 위하여 두 가지 타입의 알고리즘 사용하였는데, 현장관측에 의한 경험적 모델과 원격반사도 모델이다. 본 연구에서는 이 두 가지 방법으로 연안 지역에서의 부유퇴적물 농도추정 알고리즘을 만들어보고, 현장 관측 자료를 이용하여 두 알고리즘을 검증 및 비교해 보았다. 그 결과 2번 밴드를 사용한 경험적 알고리즘이 현장조사 자료와 가장 잘 일치하였다. 원격반사도 모델 기반의 알고리즘은 경험적 모델에 비해 높은 값을 추정하는 결과를 얻을 수 있었다. 이 연구에서 사용된 모델은 안유환(2000)에 의해 개발된 것으로서 지중해 해역의 특성에 맞도록 개발된 것이다. 따라서 해수성분요소 등의 해역 특성이 매우 다른 우리나라 해역에 맞지 않아서 생긴 결과라 생각된다. 차후에 이 모델을 우리나라 해역 특성에 맞도록 개발한다면 좋은 결과를 얻을 수 있을 것으로 기대된다.

The dinoflagellate genus Pelagodinium is genetically classified in distinct sub-clades and subgroups. However, it is difficult to determine whether this genetic diversity represents intra- or interspecific divergence within the genus since only the morphology of the type strain of the genus Pelagodinium, Pelagodinium bei, is available. An isolate associated with the genus Pelagodinium from Shiwha Bay, Korea, was recently cultured. This isolate was clustered with 3 to 4 strains from the Atlantic Ocean, Mediterranean Sea, and Indian Ocean. This cluster was distinct from the subgroup more closely associated with P. bei. The morphology of the isolate was analyzed using optical and scanning electron microscopy and was almost identical to that of P. bei except that this isolate had two series of amphiesmal vesicles (AVs) in the cingulum, unlike P. bei that has one series. When the pigment compositions of the isolate and P. bei were analyzed using high-performance liquid chromatography, these two strains had peridinin as a major accessory pigment and their pigment compositions were almost identical. In addition, the swimming behaviors of these two strains were very similar. The reexamination of the type culture of P. bei revealed two series in the cingulum as for the isolate. The new findings on the number of series of AVs in the cingulum, the pigment composition, and the swimming behaviors suggest that P. bei and the isolate are conspecific despite their genetic divergence. This study provides a basis to further understand the molecular classification within Pelagodinium combining genetic, morphological, pigment, and behavioral data.

본 연구는 토석류의 유통성과 관련하여 세립토의 흐름특성, 유변학적 모델들의 적용가능성 및 액성상태 의존성 유변학적 특성들을 비교 분석하였다. 입자크기에 따른 유변학적 특성을 살펴보고자 점토질이 풍부한 지중해 해저점토와 실트질이 풍부한 캐나다 동부 뉴펀들랜드 와부시 호수에서 채취한 광미에 대한 물성특성을 분석하였다. 점토질이 풍부한 세립토의 경우 전형적인 전단담화(shear thinning) 거동을 보이는 반면, 실트질 광미의 경우는 전단담화와 Bingham 유체 거동을 함께 보인다. 후자의 경우, 전단변형률속도를 높임에 따라 Bingham 유체처럼 거동하였다. 이러한 현상학적 차이는 입자크기에 따른 유동특성곡선의 차이에서 기인한 것이다. 항복응력과 소성점도의 결정은 전단변형에 의한 유동 입자들의 구조적 변화와 응력상태와 관련되기 때문이다. 세립토(< 0.075mm)를 다량 함유한 토석류의 유동성을 역해석하고자 할 때, 퇴적형상(흐름 양상, 퇴적층의 모양, 두께 및 길이 등)은 항복응력과 소성점도에 의해 결정된다. 항복응력과 소성점도는 액성지수의 함수로 나타낼 수 있으므로, 토석류의 발생가능지역에서 액성상태에 따른 토석류의 유동성을 평가할 지표로 활용할 수 있다.

Specimens of red algae corresponding to the peyssonnelioid genus Sonderophycus were collected at Kure Atoll, Hawai'i, at a depth range of 88-94 m depth during mesophotic surveys of the Papahānaumokuākea Marine National Monument, Hawaiian Islands, and were analyzed using morphological and molecular approaches. Analyses of mitochondrial cytochrome oxidase subunit 1 and chloroplast rbcL DNA sequences demonstrated that the Hawaiian specimens were identical to one another yet distinct from the three other species currently recognized within the genus (S. capensis [Montagne] M. J. Wynne, S. coriaceus [Womersley & Sinkora] M. J. Wynne, and S. fervens Dixon), as well as the likely congener, Peyssonnelia caulifera Okamura, and are proposed here as a new species: Sonderophycus copusii A. R. Sherwood. Sonderophycus copusii is morphologically distinct from other members of the genus by the following combination of characters: the presence of occasional secondary perithallial growth, emergence of rhizoids from the hypobasal cuticle at a strongly acute angle, a lack of horizontally directed filaments in the lower perithallus, and the lack of a stipe. This is the first record of the genus Sonderophycus in the Hawaiian Islands. Sonderophycus copusii was documented as a dominant member of the algal community at Kure Atoll, and thus may play a significant ecological role in the deep-water benthic community of Kure Atoll, along the lines of reports of deep water peyssonnelioid beds in the Mediterranean, Red Sea, and Caribbean. This study further highlights the unexplored diversity of the Peyssonneliales in Hawai'i, and emphasizes more generally the degree of as yet undiscovered biodiversity of algae at mesophotic depths.

Data collected by on-board observers and from experimental surveys during 2004-2006 were analyzed to figure out the status of shark bycatch in Korean tuna longline fishery. Results obtained from 10 surveys indicated that 14, 13 and 1 species of shark were incidentally caught in Korean tuna longline fishery operated in the Pacific, Indian and Atlantic (Mediterranean) Ocean, respectively, and that shark bycatch accounted for about 29-31% of the total catch. Sharks brought aboard were processed in 3 ways; out of 1,127 sharks observed, 575 sharks (51.0%) were discarded after finning, 299 sharks (26.5%) were stored frozen after finning for future use and 253 sharks (22.4%) were released into the sea immediately after caught. The fin to body weight ratio of sharks was estimated to be about 4.7% which is similar to the guideline of 5% established by the international fisheries organizations. The underestimate of shark bycatch in Korean tuna longline fishery was significant because it was general practice that fishermen on-board did not count the discarded shark as a catch.
