  • In North Korea, the level of scientific technical research and development is evaluated as low owing to the contradictoriness and limitations of social system. Especially the recent fisheries research fruits are embodying the scientific technical policy of the government faithfully. The characteristics of the fisheries research system and recent research movement in North Korea are summarized as follows : First, the research system is not equipped with sufficient condition for the researchers to act to the best of their individual ability on account of standardized governmental control. Second, the fisheries research activities are excuted mainly on the means of industrial problem solution rather than academic ones. Accordingly, the level of fisheries research can be estimated the same as early in 1970s in South Korea. Third, analysis by the fisheries research sectors shows that research activities on the marine fishery and aquaculture are somewhat active, but on the marine products processing are falling behind comparatively.

  • With the rapid development of China economy, many engineering projects with large scale and investment were constructed in China and some were the biggest ones in the world. With the development of engineering practice, great progress in the research of engineering management of China was made and a large number of research findings were embodied in content of research papers and were represented by technical words. To know the state of arts in the research field of engineering management in China, three major parts, namely title, abstract and keywords of research papers in last five years from three representative Chinese journals about engineering management were chose as research materials. Unlike western languages, there are no delimiters between the words of Chinese, so the maximum matching and frequency statistics (MMFS) method, a text segmentation technique of text mining Chinese, was presented to extract the features consisting of technical words, phrases and words from the research materials. Recent research and developing trend of engineering management in China were found by comparing and analyzing the difference of technical words in the research materials of last five years.

  • The emergence and spread of antimicrobial resistance in pathogenic bacteria of fish and shellfish have caused serious concerns in the aquaculture industry, owing to the potential health risks to humans and animals. Among these bacteria, Aeromonas salmonicida, which is one of the most important primary pathogens in salmonids, is responsible for significant economic losses in the global aquaculture industry, especially in salmonid farming because of its severe infectivity and acquisition of antimicrobial resistance. Therefore, interest in the use of alternative approaches to prevent and control A. salmonicida infections has increased in recent years, and several applications of bacteriophages (phages) have provided promising results. For several decades, A. salmonicida and phages infecting this fish pathogen have been thoroughly investigated in various research areas including aquaculture. The general overview of phage usage to control bacterial diseases in aquaculture, including the general advantages of this strategy, has been clearly described in previous reviews. Therefore, this review specifically focuses on providing insights into the phages infecting A. salmonicida, from basic research to biotechnological application in aquaculture, as well as recent advances in the study of A. salmonicida.

  • The time-series of Walker circulation index (WCI) in this study shows the strengthening of the Walker circulation in recent years. To further understand the large-scale features related to the WCI strengthening, a difference between the averaged meteorological variables in two time periods 1999-2013 and 1984-1998 is analyzed. The difference in 850 hPa stream flows between the two periods shows that the anomalous easterlies (anomalous trade wind) are dominant due to the strengthening of anomalous anticyclonic circulations at the subtropical Pacific of both hemispheres. The difference between the averaged zonal atmospheric circulations over $5^oS-5^oN$ in the two periods confirms that upward flows are strengthened at the tropical western Pacific and downward flows are strengthened at the tropical central and eastern Pacific in recent years. It matches the WCI strengthening in recent years. The time-series of tropical cyclone (TC) genesis frequency from July to September shows that a mean TC genesis frequency from 1999-2013 decreases compared to that of the time period 1984-1998. The monsoon trough in the period 1984-1998 was located in the further east direction and stronger than that in the period 1999-2013. TCs in the recent period that are generated in further west than TCs in the past period moved from the west. Thus, the TC intensity along the coasts in East Asia becomes weaker in recent period. The intensification of Walker circulation in recent years is related to the weaker TC intensity in East Asia through strengthened anomalous anticyclones at the subtropical western Pacific.

  • Purpose - When recovered through arbitration a contractual penalty that is disproportionately high can become grounds for challenging an arbitral award or an obstacle to its enforcement within Russian jurisdiction. This article investigates how violation of the principle of proportionality can affect the enforcement and challenging of arbitral awards in Russia. Based on the examination of the current legislation, along with the analysis of recent court cases on the subject, the ultimate object of this article is to discern practical recommendations for Korean practitioners who are looking to challenge and/or enforce arbitral awards in Russian courts. Design/methodology - The research process included the reviewing of current Russian legislation conducted in concurrence with academic literature review, searching and analyzing recent court cases where the relevant legal provisions and concepts were applied, and formulating practical implications of the research at its final stage. Findings - Through its relation to the principle of fairness/justice the authors establish the connection between the principle of proportionality and the public policy of Russia. Analysis of recent court cases showed two conflicting trends of whether a disproportionate penalty can be considered a public policy violation. The authors offer practical recommendations on how to substantiate a relevant claim regarding contractual penalty reduction by the court, depending on the desired outcome. Originality/value - The article contains an up-to-date summary of the legal provisions on the principle of proportionality of civil liability in Russia and identifies the most recent trends in court practice on the issue that is not covered by existing studies.
