Many countries in the North East Asia are competing with each other in order to become a centre of international logistics activities. The competition to become a hub port in Far East region is now fierce. The anticipated investments on improving port facilities and attracting the mega carriers are immense for all the ports in the region and the extent of the effort could cripple the local ports and region's economy given the limited financial resources. It is, however, impossible to avoid the disastrous possibility that the massive investments could be channeled into the port, which will never become a hub port, as no port is ready to currently admit defeat and settle as a small regional port. In an attempt to minimise such disastrous waste of resources, ports need to verify the eligibility of their own. This paper tests a system dynamics model using the Port of Busan to understand and illustrate the principle guideline of investment decision making for ports.

The present world economic powers are divided into three major economic blocks such as EU, NAFTA and North - east Asian Region. In N-E Asian Region, Beijing. Seoul, Tokyo and Shanghai are already bridged economically forming transaction belt with the population of seven hundred million people around the belt. The countries as China, Mongol far - east Russia are rich in natural resources. on the other hand Korea and Japan are superior in technological know-how than that of communist and socialist countries. If we try to be eager to join together with the resource rich countries to the countries of technological know - how as Korea and Japan. The North - east Asian region will be jumping up to the most prosperous and super economic power in the coming years in 2040-2050.

Being latecomers to the industrialization, Pacific rim countries except the U.S.A. are doing very little in developing the universal certification system. One should note that Asian Pacific region enjoys the highest economic growth rate, and there is a good possibility that it will be the center of economic activities of the world in the next century. It appears that ISO and CEN share similar specifications in numerous areas. ASNT is being changed to cope with the trend with the introduction of ACCP. Although we may have to adopt the new system someday, we should pay attention and make concerted effort to include our own practice in the global standards. We are the countries in the Far East Region with similar culture and tradition, which are quite different from those of western countries. We hope that Japan should play an important role in this matter, who has been chaired the ISO TC135 since 1993. In the beginning of this decade, there has been a trivial but troublesome matter that who is representing the NDT Society or member countries in Asia-Pacific Conference on NDT. The problem appears to be solved since the establishment of FENDT For the next decade, actually next centry, FENDT will have to accomplish another important role for countries in the Far East Region to form a strong coalition for its survival in the western dominant world. Immediate issue is to establish Far East Working Group for Harmonization and Mutual Recognition of Qualification and Certification of NDT Personnel. To realize this Japan must play a leading role with the cooperation of expanded FENDT member countries including China and Russia. As the continued prosperity expected in this region, FENDT should continue its role for the next centry. We, the FENDT countries, must move forward for internationalization(國際化). However' we must realize that it all start from SELF IDENTI-FICATION. We can identify ourselves by actively participating in FENDT. I would like remind you the concluding remark that I have made in the congratulatory speech at JSNDI 40th Anniversary Conference and FENDT'92. JSNDI is too precious to be Japan's sole possession Staling from the Far East, JSNDI shall become one of the loaders of the world. I sincerely hope that JSNDI take initiatives and leaderships in the future activities. of FENDT countries. I would like to close my talk with "We must hang together, or We shall be hang seperately."

The purpose of this study is to outline the strategic implications of a structure analysis and trends of transferred air cargoes for the main airports of the North Asian region for 13 years from 2000 to 2012. To do so, it analyses the concentration levels using a Gini coefficient and Hirschmann Herfindahl index and represents the competitive positioning with regard to the main East Asian airports using the BCG framework and shift-share analysis. Currently, the concentration level is getting weaker in response to the emergence of Chinese airports in the north-east region. It is likely that the steady growth of air cargo of Shanghai airport (PVG) has caused the increase in concentration levels in the region. Seoul airport (ICN) may be directly in competition with PVG for air cargo in the region, giving consideration to reducing or maintaining an average increase ratio of air cargoes of ICN, NRT (Tokyo), and KIX (Osaka) for same period. In the same sense, the average increase in ratio for ICN for same period yields 1.3%, which is far behind the 6.2% and 5.2% of the north-east region and PVG respectively. Additionally, shift-share effect analysis indicates that ICN lost 422,180 tons in the north-east region during the same period, suggesting that transferred cargoes might have been forwarded to PVG.

Power semiconductors are semiconductors capable of controlling power over 1W and are mainly used as switches. This power semiconductor device has been developed with the goal of reducing power consumption and high breakdown voltage. This research was analyzed electrical characteristics of IGBT(Insulated Gate Biopolar Transistor) according to diffusion length of JFET region. The Diffusion length of JFET region was controlled by temperature and time using T-CAD simulator. As a result of experiments, we could obtain 1.14V low on state voltage drop by fixing 1440V breakdown voltage.

The Bering Strait crossing would link the entirety of Eurasia to the entirety of the Americas, and it can be seen as a natural extension of the historical Silk Road. There are some immense geopolitical benefits to such a project. It would bring about a profound and lasting change to the global economic and political outlook. The most valued function of the Bering Strait crossing and the extension of the associated railroad network would be to release the massive natural resources trapped underneath the tundra and permafrost for the benefit of Russia and the world. Moreover, the railroad project(s) would also build development corridors in those underdeveloped parts of the Russian Federation. The development of the resources and their rapid transportation to the global markets would contribute not only to the overall development of the region but also would be valuable for the resource-poor countries of Northeast Asia such as Japan, Korea, and China (relative to its economic size). This paper will explore the possible impact(s) of the Bering Strait crossing as a formidable infrastructure project for the economic development of the Russian Far East (RFE) from the Russian perspective under the frame of geopolitics. Furthermore, it will equally scrutinize the implications for the adjacent countries in the region.

Trends toward an influx of new migrants have been pronounced in East Asia through a development we call the third round of migrant incorporation. At the same time, other features of East Asian societies, such as strong levels of ethnic nationalism, have changed little, posing challenges to multiculturalism. In this introduction to this special issue, we review the latest research trends broadly concerning multiculturalism, migrant groups that have received little attention, racism and xenophobia. We first discuss the state of migrant incorporation in East Asia and the limits of multiculturalism in this region, where various features of the developmental state persist. We then introduce research on voices opposing multiculturalism in East Asia. This introduction highlights what is peculiar―and ordinary―about migrant incorporation and the associated challenges in East Asia.

This study evaluates the performance of the Weather Research and Forecasting (WRF) model in reproducing the present-day (1981~2005) precipitation over Far East Asia and South Korea. The WRF model is configured with 25-km horizontal resolution within the context of the COordinated Regional climate Downscaling Experiment (CORDEX) - East Asia Phase 2. The initial and lateral boundary forcing for the WRF simulation are derived from European Centre for Medium-Range Weather Forecast Interim reanalysis. According to our results, WRF model shows a reasonable performance to reproduce the features of precipitation, such as seasonal climatology, annual and inter-annual variabilities, seasonal march of monsoon rainfall and extreme precipitation. In spite of such model's ability to simulate major features of precipitation, systematic biases are found in the downscaled simulation in some sub-regions and seasons. In particular, the WRF model systematically tends to overestimate (underestimate) precipitation over Far East Asia (South Korea), and relatively large biases are evident during the summer season. In terms of inter-annual variability, WRF shows an overall smaller (larger) standard deviation in the Far East Asia (South Korea) compared to observation. In addition, WRF overestimates the frequency and amount of weak precipitation, but underestimates those of heavy precipitation. Also, the number of wet days, the precipitation intensity above the 95 percentile, and consecutive wet days (consecutive dry days) are overestimated (underestimated) over eastern (western) part of South Korea. The results of this study can be used as reference data when providing information about projections of fine-scale climate change over East Asia.

1. Mt. Soyo is situated in the central part of Korea, approximately 37$^{\circ}$56'W. Latitude, 127$^{\circ}$4'N. Longitude. This mountain is about 530 meters above sea level, and consists mainly of granites. Above 200 meters the area is covered with oak trees (Quercus mongolica, Q. aliena) with a kind of Rhododendron (Rhododendron mucronulatum, R. schlippenbachii) as undergrowth. About 500 packets of bryophytes were collected by the writer in 1959. 2. The mosses collected in this region were of 68 species belonging to 51 genera. Those species may roughly be divided, as follows; 1) 15 species (22.1%) are distributed also in Europe and North America (Holarctic element). 2) 2 species (2.9%) occur also in Kamchatka and the Aleutians (North Pacific element). 3) 14 species (20.6%) are widely distributed every where (Cosmopolitan element). 4) 19 species (27.9%) occur also in the temperature region of the Far East (East Asiatic element). 5) 3 species (4.4%) occur also in Indomalaya and India (Tropical element). 6) 15 species (22.1%) are endemic to Japan and Korea. 3. The Hepaticae collected in this region are of 11 species belonging to 7 genera. Those may roughly be divided, as follows; 1) 4 species (36.4%) are distributed also in Europe and North America (Holarctc element). 2) 5 species (45.5%) occur also in the temperature region of the Far East (Asiatic element). 3) 1 species (9.1%) occur also in Indomlaya. 4) 1 species (9.1%) are endemic in Japan and Korea. 4. The species which are new to the flora of Korea are as follows; 1) Leucobryum glaucum (L.) Schimp. 2) Psedoleskeopsis dicurvata (Mitt.) Broth. 3) Thuidium delicatulum (Hedw.) Mitt. 4) Dolichotheca perrobustum (Broth.) Broth. 5) Brachiolejeunia sandvicensis (Gott). Evans. 6) Porella vernicosa Lindb. ssp. gracillina (Mitt.) Ando.

Worldwide, avian influenza H9N2 viruses of different lineages are the most widespread viruses in poultry. However, to date, cases in Russia have not been documented. In this study, we report the first detection of a G1-like H9N2 virus from poultry sampled at live-bird markets in Russia (Far East region) during the winter of 2018 (isolate A/chicken/Amur_Russia/17/2018). We assume there has been further circulation of the A/chicken/Amur_Russia/17/2018 H9N2 virus in the Russian Far East with possible distribution to other regions or countries in 2018-2019.
