We studied on the relationship between oceanic variation in the offshore and abnormal sea surface temperature rise in the coastal area of the Yellow Sea using a variety of satellite and in-situ data during winter 2004. In results of the satellite data, the average value of sea surface temperature in the Yellow Sea for 2003 was $10^{\circ}C$, and the average value of sea surface temperature for 2004 was $13^{\circ}C$. It was higher than those of the last year about $3^{\circ}C$. In results of the in-situ data, the average value of surface layer temperature in the Yellow Sea for 2003 was $9.85^{\circ}C$, and the average value of surface layer temperature for 2004 was $12.17^{\circ}C$. In the same satellite data, it was higher than those of the last year about $3^{\circ}C$. In results of the T-S diagram, we divided definitely into water mass of the Yellow Sea and the East China Sea in 2003. But we didn't divide definitely into water mass of the Yellow Sea and the East China Sea in 2004. The average values of air temperature and wind speed for 2003 were $5.23^{\circ}C$ and 4.81 m/s, respectively. And, the average values of air temperature and wind speed for 2004 were $5.61^{\circ}C$ and 4.52 m/s, respectively. So, These were similar. But the wind directions for 2003 were superior northwestern wind, and the wind directions for 2004 were various northern wind. The wind directions were different from each other. Therefore, the abnormal sea surface temperature rise in the coastal area of the Yellow Sea during winter 2004 were better related to oceanic variation in the offshore than influences of atmosphere. In the future, We will do in-depth study for these.

Recently China's science and technology development is accelerating, and some technologies have the world's best technology. With the rapid development of science and technology, China has been deeply aware of the importance of science and technology, and many efforts are being made to legislate security regulations to protect their technologies. Korea and other countries are also interested in research security, and research and development cooperation with China is also on the rise. In this paper, we derived some implications by comparing and analyzing China's science and technology security regulation and Korea's national R&D project management regulations. China is also enacting science and technology security regulations as a subordinate to the laws and regulations of science and technology. However, it should be reflected in future legislation that the difference from Korea is composed of separate independent regulations. In particular, the fact that the science and technology security regulations have been enacted separately may be a hint that can be reflected in the nation's future legislation processes. In this paper, major contents of the science and technology security regulations, points to division of knowledge property into scientific and technological cooperation or security tasks, designation of regulations on the characteristics of research security guidelines, and operation of individual national security agencies In addition, in the event that the contents of the related statutes, confidentiality provisions, and import and import control are recorded in this paper, and the results of the joint R&D project are not utilized, or the technology transfer is not carried out.

In the digital age, innovation is at the heart of information technology development. This paper explores the differences of regional innovation capabilities from within the innovation system from a new perspective. By applying the coupling coordination degree model, the coupling coordination degree analysis is conducted for the three systems of innovation (innovation input, innovation output, and innovation environment) in 31 provinces, municipalities, and autonomous regions of China. The results show that: the overall level of coupling coordination degree in China is low, and the number of provinces in good coordination and quality coordination is low number, but they are all distributed in the eastern economically developed regions, showing a high correlation between regional innovation and regional economic development. The overall trend of China's innovation coordination is on the rise. The research results of this paper can provide a new perspective for the evaluation of innovation capability, and also provide an important impact of innovation on promoting the development of ICT industry.

The establishment of the WTO system means that the global age of trade has officially arrived. Since the integration of the world economy brings about the free movement of goods and services between nations, it is inevitable that sea-bound freight will continue to increase. A recent World Bank report says that China and Korea will be the first and seventh largest economic Powers, respectively, by the year 2020. In particular, the Korea peninsula has a geo-political advantage in being developed as a major Northeast Asian container center. Moreover China's swift uprising needs new order of trade for economy belt in Northeast Asia. Therefore, it can be said that Kunsan Port. which has already been designated as a free trade zone, has greater potential to rise as a regional beach-head port and main region for foreign investment. As such. Kunsan Port will play a major role in accelerating the emergence of the West Sea in international trade. There are several strategies for developing Kunsan Port into a central container port: 1) develop Kunsan port Into an import/export front base f3r multinational corporations, 2) develop Kunsan container port into the core composite container-linked central port, 3) attract foreign investment to the Kunsan Free Trade Area so as to promote balanced development among the regions of Korea, 4) support the central government and local governments to accelerate the coming of the "West Sea Era." These recommendations call for urgent implementation.

Concrete filled steel tubular (CFST) member has been widely used in the construction of high-rise buildings for its high axial bearing capacity. It can also be applied on long-span structures such as spatial structures or bridges not only for its high bearing capacity but also for its construction convenience. Concrete casting effect of CFST member is considered in the study of its bearing capacity in this paper. Firstly, in order to authenticate the applicability of constitutive relationship and yield criterion of steel and concrete based on FEM, two ANSYS models are built to simulate and compared with other's test. Secondly, in order to find the huge difference in bearing capacity due to different construction processes, two full-size CFST models are studied when they are horizontally cast and axially compressed. Finally, the effects of slenderness ratio (L/D) and confining parameter (D/t) of CFST members are studied to reveal the intrinsic links between bearing capacity and slenderness ratio or confining parameter.

When the People's Republic of China destroyed one of its own defunct meteorological satellites, the Fengyun-1C, at an altitude of some 865 km above the earth's surface, the PRC was accused of initiating, or at the very least risking an(other) arms race in outer space also. The test also gave rise to a few legal questions as to the permissibility of this test, and the broader permissibility of using space for military and other weapon-touting activities, Whilst the test cannot be considered to constitute a direct threat to international peace and security so as to invoke relevant legal principles and consequences in terms of the UN Charter for example, it highlights the importance of such clauses in international space law as requiring international cooperation and consultation, due regard for the interests of all other countries both on earth and in outer space, and the further development of general regimes of registration and space debris-prevention. From that perspective, the PRC violated international outer space law not so much by the test itself but by the accompanying lack of information, consultation and due regard for other states', and indeed mankind's, interests.

Total debt in the People's Republic of China surged to nearly 290% as a ratio to GDP by the second quarter of 2016, mostly on account of non-financial corporate debt. The outpouring of credit to stem the impact of the global financial crisis accentuated industrial overcapacity in traditional sectors, such as steel, cement, and energy, while feeding asset bubbles in the property, equity and bond markets. At the Chinese corporate level, this has translated into weakened fundamentals and a fall in industrial profits, particularly of SOEs. As debtors struggle to service interest payments, non-performing loans (NPLs) have been on the rise. This paper assesses the financial fragility of the Chinese economy by looking at risk factors in the non-financial sector. We apply quantile regressions to a dataset containing all Chinese listed companies in Standard & Poor's IQ Capital database. We find higher sensitivity over time of corporate leverage to some of its key determinants, particularly for firms at the upper margin of the distribution. In particular, profitability increasingly acts as a curb on corporate leverage. At a time of falling profitability across the Chinese non-financial corporate sector, this eases the brake on leverage and may contribute to its continuing increase.

Exploring innovations for latecomers to catch up has been a popular concern in industry and academia. Over the last decade, more and more East Asian latecomer firms have moved beyond imitation and are delivering innovative products and services to the market. However, the semiconductor latecomers from China have limited success in catching up with more mature semiconductor firms. Our study examines how semiconductor latecomers to break through the latecomer's dilemma by innovation and achieve catch-up. We use a single-case approach for the Semiconductor Manufacturing International Corporation (SMIC) vertical development process to analysis its innovation path of catching up. The study's results showed that SMIC relied on the government's policy and funding support, and based on the strategic endurance of entrepreneurs, it persisted in technology R&D investment and independent innovation for 20 years. SMIC finally smashed the dilemma of latecomers and successfully achieved catch-up. With these findings, we believe that the path of catching up innovation for semiconductor latecomers should be equipped with independent innovation of technology, strategic leadership of entrepreneurs and support of government policies. As these factors are combined, latecomer firms' position is expected to rise and catch-up will become visible. Our study contributes to some enlightenment on the innovation path for latecomers in China and global semiconductors to achieve their catch-up.

The aim of this study was to examine the trend of ovary cancer incidence from 1999 to 2010 in China and predict the burden up to 2020. Crude incidence, age specific incidence and age-adjusted incidence rates were calculated. Joinpoint regression was performed to obtain estimated annual percentages and Bayesian age-period-cohort modeling was used to predict the incidence rate until the year 2020. In China, the crude rate of ovary cancer was 7.91/100,000 and the age-adjusted rate was 5.35/100,000 overall during period 1999-2010. The rates in urban regions were higher than in rural regions. A significant rising trend during 1999-2006 was followed by a drop during 2006-2010 in age-adjusted rates for urban females. In contrast, constant rise was observed in rural women. The decrease in ovary cancer of urban areas tended to be restricted to women aged 50 years and younger. In contrast, increases of ovary cancer in rural areas appeared in virtually all age groups. Although the age-adjusted incidence rate for ovary cancer was predicted to be reduced after year 2011, the crude rate was likely to be relative stable up to 2020. The burden of ovary cancer in China will continue to be relative stable due to the aging population.
