  • This paper intends to study some problems in the application of UCP 600 in the international trade transactions with China. Generally speaking, China complies with UCP 600 well. Nevertheless, there are some problems in the application of UCP 600 in China owing to the difference in law and practices. There are some problems in the application of UCP 600 in China owing to the difference of practices under Bills of Exchange Act and The Provisions of the Supreme People's Court on Some Issues Concerning the Trial of Cases of Disputes over Letter of Credit. The Act insists on the formal requirements, the consistency between a letter amount and a figure amount, the unconditional payment character of bills of exchange. The Provisions include the recognition of revocable credits, the difference of standard in examining documents, the difference in the treatment of issuing banks in relation to discrepant documents. These aforesaid matters of the Act and the Provisions are inconsistent with the practices under the UCP 600. There are two main problems in the operation of letters of credit in China. One is the lack of concerned parties' practice knowledge in relation to letters of credit in China. The other is the inactive stance of nominated banks in China. There are two main problems in relation to judiciary institutions in China. First, judges in China tend to abuse the injunctions owing to the lack of understanding in relation to letters of credit. Secondly, there are inconsistency in the court ruling in China.

  • Since the onset of its economic reform and the open door policy in the late 1970s, China's overall economic growth rate has been continuing about 10% per year. The marine sector is not allowed exception, aquatic products increased sharply from 4.66 million MT in 1978 to 36.02 million MT in 1997, and then China is remained the largest producing country in the world aquatic market and her role would be expanded. Korea having a common boundaries to China is subjected unescapably both in domestic and export markets by the influence of the remarkable growth of China's aquatic products. If China were admitted entrance of WTO(World Trade Organization)in the near future, her influence is getting more serious. Well, we are necessary to understand the characteristics of China's aquatic products and to review fishery policies implemented by the China government. This paper is organized into two major parts, the one includes the structural changes of aquatic products, fishing and cultivating in the coast, latent and estimated production in China, and the other includes the main contents of fishery policies and measures of government administration. A characteristic of China's aquatic products is that cultivated production, especially, shellfish outputs continues to rapid increase. The major means of administration are an execution of fishing license system and setting up no-fishing zone and closed season for fishery. China is no longer a marginal player in international economic and world aquatic market. So, we will not only understand China's aquatic conditions and problems, but will also see the usefulness in continuing the cooperative relationship for a long time to come.

  • To study the lubrication performance of tilting-pad thrust bearing (TPTBs) during start-up in nuclear pump, a hydrodynamic lubrication model of TPTBs was established based on the computational fluid dynamics (CFD) method and the fluid-structure interaction (FSI) technique. Further, a mesh motion algorithm for the transient calculation of thrust bearings was developed based on the user defined function (UDF). The result demonstrated that minimum film thickness increases first and then decreases with the rotational speed under start-up condition. The influence of pad tilt on minimum film thickness is greater than that of collar movement at low speed, and the establishment of dynamic pressure mainly depends on pad tilt and minimum film thickness increases. As the increase of rotational speed, the influence of pad tilt was abated, where the influence of the moving of the collar dominated gradually, and minimum film thickness decreases. For TPTBs, the circumferential angle of the pad is always greater than the radial angle. When the rotational speed is constant, the change rate of radial angle is greater than that of circumferential angle with the increase of loading forces. This study can provide reference for improving bearing wear resistance.

  • China adopts the "Outline of the 14th Five-Year Plan for National Economic and Social Development of the People's Republic of China and the Long-Range Objectives Through the Year 2035" in the context of tremendous changes in the international environment. A new development paradigm is proposed to prioritize domestic circulation, reinforcing both domestic and international circulations. The industrial policies of China's "14th Five-Year Plan" will have an impact on Korea. Thus it is necessary for Korea to cooperate with China to actively respond to changes in the industrial chains and value chains in Asia and the world. Over the past 29 years since the establishment of diplomatic relation between China and South Korea, the two countries have enjoyed close economic and trade relations. China-ROK cooperation is critical to regional economic development in the Fourth Industrial Revolution and the era of remarkable changes in the world's political and economic structure. China is a robust developing country, while Korea is a developed one in with steady foothold in the world economy. China and South Korea should work together to contribute to the rapid recovery and development of the world economy instead of becoming competitors.

  • We present a Yb-doped narrow-linewidth polarization-maintaining all-fiber amplifier that achieves a high mode-instability (MI) threshold, high output power, and 9.7-GHz spectral linewidth. Six wavelength-multiplexed laser diodes are used to pump this amplifier. First, we construct a high-power fiber amplifier based on a master oscillator-power amplifier configuration for experiments. Subsequently, we examine the MI threshold by individually pumping the amplifier with wavelengths of 976, 974, 981, 974, and 981 nm respectively. The experimental results demonstrate that the amplifier exhibits a high MI threshold (>3.5 kW) when pumped with a combination of wavelengths at 974 and 981 nm. Afterward, we inject an optimized phase-modulated seed with a nearly flat-top spectrum into this amplifier. Ultimately, laser output of 3.2 kW and 9.7 GHz are obtained.

  • This study is aimed to investigate how the structure of Korean and Chinese fisheries has been changed since the Fisheries Agreement between Korea and China came into effect. This investigation was accomplished from a comparative point of view by using statistic data in the literatures published by both Korea and China. Results of this study are summarized as follows; First, it was revealed that the decreasing rate of fish production of marine capture fisheries in Korea was lowered more by 5.1%, while it was decreased by only 0.1% in China. Second, comparative results on changes in production of offshore fisheries showed that the production of Korean offshore fisheries in 2003 was reduced by 26% compared to that in 1999, while the production of China offshore fisheries was decreased by 22%. In addition, although the production of marine capture fisheries in the East region of China was reduced by 10%, on the contrary, the production of marine capture fisheries in Liaoning, Hebei, Tianjin, Jiangsu, Zhejiang, and Fujian that have mostly impacted by the Korea-China Fisheries Agreement was increased by 7%. Third, results on fishing capacity of marine fisheries indicated that the number of vessels and total horse power in Korea were increased by 1.2% and 44.9%, respectively, while total tonnage was reduced by 23.9%, For China, the number of vessels and total horse power were increased by 0.5% and 12.6%, respectively. Total tonnage was also increased by 11.7%. Finally, the production per Korean vessel was decreased by 17.8% in 2003 compared to that in 1999. On the contrary, the production per Chinese vessel was increased by 8.1% in 2003. The production per tonnage was increased by 3.2% in Korea, while it was reduced by 2.7% in China. In conclusion, it could be said that the Korea-China Fisheries Agreement has had a positive impact on the fisheries production of China, while it has had a negative impacts on that of Korea, relatively.

  • The legislative body of The People's Republic of China, the National People's Congress, enacted the first arbitration act in China's history on August 31st, 1994, which took effect on September 1, 1995. The problems revealed through a comparison of China's Arbitration Act with the UNCITRAL model arbitration law were studied as well as the enacting process, background, status and system, important contents, problems of Chaina's Arbitration Act, and the differences between the old arbitration regulations and the new arbitration act. These are all discussed in this paper. The Arbitration Act is the basic act ruling over china's arbitration system: it unified the previously confusing laws and regulations relevant to the arbitration system, and the act brings out fundamental changes in China's domestic arbitration to the level of international arbitration standards. It is possible to view this act as a cornerstone in China's arbitration system. But, as discussed in this paper, there are still a lot of problems with the new act and only a few of the merits which the UNCITRAL model arbitration law has. First, under China's Arbitration Act, parties enjoy autonomy to some degree, but the range of party autonomy, compared to that of the UNCITRAL model arbitration law, is too narrow. Second, because China's Arbitration Act didn't explicitly provide issues which can give rise to debate, a degree of confusion in its interpretation still remains. Third, China's Arbitration Act's treatment of some important principles was careless. Fourth, in some sections, China's Arbitration Act is less reasonable than the UNCITRAL model arbitration law. These problems must be resolved in order to develop China's arbitration system. The best way of resolving these problems for China is to adopt the UNCITRAL model arbitration law. But it is difficult to expect that China will accept this approach, because of the present arbitration circumstances in China. Although it is difficult to accept all the contents of the UNCITRAL model arbitration law, China's legislators and practitioners must consider the problems mentioned in this paper.

  • As international trades between Korea and China increase, the number of civil disputes also increases. The civil dispute settlement system and the court system in China are distinctive from those of Korea. China has its own court systems which are characterized by the Chinese Communist System. Due to the influence of the decentralized local autonomy tradition, the case laws of each Province in China are not unified throughout the China. This is partly because only two instances are provided in China, and the parties cannot appeal to the Supreme People's Court of China unless there is a special reason. In Korea, three instances are provided and parties can appeal to the Supreme Court if a party so chooses. In addition, there are many differences in the judicial environment of China compared to Korea. Therefore, if there is a dispute between a Korean party and a Chinese party, arbitration is recommended rather than court litigation. This article examines the points to be considered for interim measures in China during arbitration. Where the seat of arbitration is Korea, interim measures cannot be taken by the order of the Chinese court in the middle of or before arbitration procedures. On the other hand, it is possible to take interim measures through the Chinese court in the middle of or before the arbitration procedure in China or Hong Kong. It also reviews the points to be noted in case of the enforcement of arbitration awards in China where permission from the upper Court is required to revoke or to deny the recognition or enforcement of a foreign-related or foreign arbitration award.
