  • Hydrographic surveys were carried out four times in the western channel of the Korea Strait in March and August 2003 and in June and November 2004. The bottom cold water, which was lower than $10^{\circ}C$, appeared in the channel trough except in March 2003. It flowed southwestward along the shelf of Korean coasts in August 2003 and in November 2004. The width and the maximum speed of the intrusion current were about 20 km and approximately $25\;cm\;s^{-1}$, respectively, off Ulsan, Korea. The volume transport of the bottom cold water was estimated 0.019 Sv ($Sv{\equiv}10^6\;m^3\;s^{-1}$) in August 2003 and 0.026 Sv in November 2004.

  • The Korea Strait comprises a continental shelf in a shallow sea that experienced glacio-eustastic sea-level changes during the Quaternary period. A long core of 76.6 m in length was acquired at the South Sea Drilling Project site (SSDP-101; 34°19.666'E and 128°16.335'N) with a 60 m water deep. The uppermost massive sand beds were interpreted as sandy sediments of the nearshore marine sand ridge in the shallow sea during the transgression of sea level, whereas the lower parts of alternating sandy and muddy beds were interpreted as deposits in marsh, estuary, and tidal flat environments. A three-layered geoacoustic model was reconstructed for the sedimentary succession in the high-resolution seismic profile based on a 140-grain size and sediment type of core SSDP-101. For the actual underwater simulation and experiments, the in-situ P-wave speeds were calculated using the sound speed ratio of the Hamilton method.

  • By use of the oceanographic data from 1932 to 1941 and from 1960 to 1967, the general properties of the cold water in the Korea Strait are discussed. This water characterized with temperatures 3-10$^{\circ}C$ and salinities 34.0-34.4 originates from the Japan Sea and begins to flow out in summer along the bottom about 8 to 18 miles southeast of Ulgi in Ulsan. It usually reaches the Pusan- Tsushima section and rarely to the west of the southernmost part of Tsushima. As it flows out, it shows rising trend along the coast of Korea and sometimes upwelling occurs in the vicinity of Ulsan. It seems that the cold water forms an under current along the bottom in summer and autumn in the western channel of the Korea Strait.

  • Two lichomolgoid copepods, Lichomolgus inflatus Tanaka and Philoconcha paphiae Yamaguti, both known very rarely since the original descriptions, are redescribed based on the specimens discovered as associates with the bivalve Dosinorbis japonicus from the Korea Strait. Lichomolgus inflatus is very closely related to L. chamarum Humes, but can be differentiated by the features of the rostrum and genital double-somite. Philoconcha paphiae is found to have an extremely variable leg armature. This is the first discovery of the two species of copepods outside the Japanese waters.

  • Thirteen pelagic species of mysids, representing nine genera, are reported from the Korea Strait and its adjacent waters. Of these, seven species, Doxomysis quadrispinosa, Meterythrops microphthalma, Pleurerythrops secunda, Pseudanchialina pusilla, Siriella gracilis, S. okadgi, and S. thompsoni, are newly recorded from the Korean waters. A taxonomic key and illustrative figures are given.

  • New cotidal charts of the Tusima Strait has been edited by ODAMAKI (1989a) using tidal current observation data. For the semidiurnal tide as shown in Fig.1, two distinctive features are detected. One is an anti-amphidromic area located in the south coast of Korea. Another is the amplitude gap between west and east coasts of the Tusima.(omitted)

  • A new species of ianirid isopod from a subtidal bottom in the Korea Strait is described and illustrated under the name of Juniralata koreuensis. This species is characterized by the cephalon lacking a distinct rostrum and prominent antero-lateral expansions, the pleotelson lacking postero-lateral projections, and the male pleopod 1 having a nipple-shaped lobe on lateral apex.

  • China Coastal Water(CCW) appeared in the neighbouring seas of Cheju Island has been analyzed and the results are as follows: The water with salinity below $32.20\%0$ in the neighbouring seas of Cheju Island in summer is thought CCW. During the period from April 1985 to August 1986, salinity of more than $34.00\%0$ was appeared in the Cheju Strait during January to mid May, but it decreased gradually from late May. CCW with salinity below $32.20\%0$ appeared in the Cheju Strait in early July and disappeared in October. The mean thickness of CCW in the Cheju Strait was about 25m and CCW had an influence of up to about 50m depth. And stratification structure of the Cheju Strait in summer was halocline between the surface and 50m depth and homogeneous salinity layer below 50m depth. It seems that although CCW appears in the wide area of neighbouring seas surface of Cheju Island in summer, the core of this CCW which has the lowest salinity flows into the Cheju Strait from the western seas of Cheju Island. This CCW flows out the east through the central part of the Cheju Strait and then seems to be transported further in the form of eddy.

  • As the disputes in the investment and civil/commercial sectors of China and Taiwan have increased due to active cross-strait economic exchanges, the Chinese government is addressing cross-strait disputes through various dispute resolution methods. In recent years, the Arbitration Center Across the Straits (ACAS) has been established to resolve disputes between cross-strait parties, while ACAS Arbitration Rules have been enacted and enforced. ACAS Arbitration Rules are prepared by referring to the Arbitration Act of China and Taiwan, the relevant provisions and practices of the China International Economic and Trade Arbitration Commission (CIETAC) Arbitration Rules and the cross-strait practical affairs of the China International Economic and Trade Arbitration Commission, and the cross-strait practical affairs giving consideration to the specificity of the cross-strait relationship and the characteristics of economic and trade disputes. Therefore, this paper has compared the features and main contents of the ACAS Arbitration Rules with those of the CIETAC Arbitration Rules. This refers to arbitration proceedings such as form and effect of arbitration agreement, decision of place of arbitration, and organization of arbitral tribunal; the provision of consolidation of multiple contracts and arbitration, and the provision of joinder of arbitration parties, which are implementing the "principle of party autonomy" with streamlining arbitration proceedings and reducing costs; "common, simple, and small sum arbitration proceedings which require shorter arbitration proceedings depending on the size of the arbitration object; and regulations on the "interconnection of mediation and conciliation" which is characteristic of China's arbitration system. Based on the above-mentioned main contents of the ACAS Arbitration Rules in China, there are some implications to be considered in the establishment of the Arbitration Rules of the South-North Commercial Arbitration Commission which will be applied to solve commercial and investment disputes arising from the Inter-Korean Economic Cooperation process, suggesting implications such as the need for the rapid composition and operation of the South-North Commercial Arbitration Commission, requirements for selecting arbitrators, expansion of the object of arbitration, specification of concreteness in deciding the place of arbitration, need to create a variety of arbitration proceedings, and application plan of the International Center for Settlement of Investment Dispute (ICSID) or Third Power Arbitration Agency.

  • Sparker profiles and sediment cores collected from the Korea Strait show a distinct pattern of stacked prograding wedges consisting of three distinct units. These wedges are interpreted as the lowstand deposits formed during glacioeustatic sea-level lowstands. Repeated sea-level falls during late Pleistocene with high sediment discharge from the paleo-Nakdong River system resulted in the formation of thick lowstand wedges.
