  • The taxonomic revision of the family Uranoscopidae from Korea was made on the basis of the speciemens collected in the coasts of the Korea from 1986 to 1994. The key to the species and genera for classification of the famiiy Uranoscopidae was provided with synonym and their distributions. The stagazer fishes from Korea are composed of 6 species in 3 genera: Uranoscopus Japonicus, U. bicinctus, U. chinensis, U. tosae, Gnathagnus eolngatus and Ichthyscopus lebeck sannio. The Korean stagazer fishes were widely distributed in the West and South Sea of Korea, but only Ichthyscopus lebeck sannio distributed in the around sea of Cheju Island.

  • In 2019, the U.S. Department of Defense and the U.S. Department of State issued two reports to announce their plan to fulfill "free and open Indo-Pacific". Two reports commonly insisted on the support and participation from allies and partners to maintain security and stability in the Indo-Pacific. In response to this, neighboring states in the Indo-Pacific, including Japan, Australia, India, ASEAN, and Taiwan have different perspectives and stances based on their national interests. South Korea, too, has not clearly announced its position because they need to consider the alliance between the U.S. and South Korea as well as relationships between South Korea and China. This report focuses on the stances of neighboring states to the Indo-Pacific strategy and expected pros and cons of the participation of the strategy. In addition, when considering the name of strategy, the Indo-Pacific, naval power will be a main instrument to implement the strategy. Thus, this study also investigates the role of naval power in the Indo-Pacific strategy.

  • The South Korean society has experienced many changes since the sinking of ROKS Cheonan. The government reviewed its defense posture and adopted the 5·24 Measure in its relations with North Korea. As a result, the people of South Korea became more conscious of security situations on the Korean peninsula while North Korea's economy suffered badly. Meanwhile, the South Korean government has taken a flexible stance toward North Korea in terms of exchange and cooperation since September 2011. The flexible stance was to manage inter-Korea relations in a stable manner and relieve the hardships of the North Korean people while preserving the spirits and purposes of the 5·24 Measure. The UN Security Council adopted twenty-six resolutions and statements on North Korea since June 25, 1950. They include thirteen U.N. Security Council resolutions including those concerning nuclear weapons or missile programs, nine Presidential statements, and four press statements. Resolution 82, the first U.N. resolution on North Korea, came when the Korean War broke out. Resolution 825, the first one related to nuclear or missile programs, was adopted in response to North Korea's withdrawal from the NPT. Apart from these U.N. resolutions, the United States has imposed separate sanctions against North Korea. North Korea's nuclear weapons program can be considered in comparison with that of Iran in terms of the consequences they create for the regional security. The Security Council has adopted six resolutions on Iran so far. One should note that the resolutions on Iran have had much stronger sanctions compared to those imposed on North Korea. That is, while the North Korea case may be viewed as a more serious threat to international security from the perspective of nuclear weapons development or proliferation, tougher sanctions have been placed on Iran. There are two approaches that South Korea should take in addressing the related issues. First, we should aim to reduce the gap between sanctions imposed on Iran and North Korea. It is difficult to understand that a country with more serious problems is rewarded with lighter sanctions. We should take measures through the Security Council Sanctions Committee to make individuals and groups in North Korea that play a central role in developing nuclear weapons and missiles subject to additional sanctions. Second, we have to change. Other countries in the international community have become tired of North Korea's nuclear issue and now they look to South Korea for initiative. We should correctly understand this current situation and play a leading role within our capacity. Knowingly and unknowingly, the notion that the North Korean nuclear issue may be left to South Korea has been spread around the international community. Although the situation is grave, we should try to open a new horizon in ushering in the unification era by taking the initiative with confidence that there is a looming hope ahead of us. For these tasks, we should stop thinking in the old way that has been ossified for the last two decades. We should not be pushed around by neighboring great powers in dealing with North Korea related issues anymore; we should take the initiative with resolution that we will play our role at the center of four great powers and with confidence that we can do it. Based on the confidence that the Republic of Korea has become a country with enough capacity to take the initiative, we should establish a 'National Grand Strategy' representing South Korea's strategic vision that the unification is the ultimate solution to the problems related to North Korea's nuclear weapons program.

  • The Pacific Island Forum that consists of 14 island countries in the South Pacific has long been the focus of keen attention from East Asian countries such as South Korea, Japan and China. The South Pacific area was controlled by Japan right after the First World War. The League of Nations bestowed the right of trusteeship over the region to Japan, one of the victors in the war. However, the U.S. considered the area indispensible for its security interests in the Pacific after victory in the Second World War. With the end of Cold War period, the region again began to gain the competitive attention of Japan, China and Korea. Japan has made efforts to give economic assistance to this region by holding the Japan-Pacific Islands summit every three years. In addition, Japan is promoting a security engagement with this region by dispatching Self Defense Forces with the aim of initiating construction and development projects. In response to Japan's active involvement in the region, China also began to convene a summit meeting with these countries in 2006, making pledges of economic assistance. Furthermore, Chinese civilian companies struck deals of investment with municipal institutions in the region with a view to enhancing China's influence in the region. Japan's and China's active engagement in the region has galvanized South Korea to craft a more effective strategic approach to the region.

  • Keeping in mind the hybridity and plurality of Southern Literature, this paper discusses the traits of Southern literature in Jayne Ann Phillips's first novel, Machine Dream. The novel's frequent use of memory and oral reconstruction of a family history accompanied by the feeling of loss in the process of depicting the South's past typically signifies "The Southern" which reminds us of the works of William Faulkner, Katherine Ann Porter, and Eudora Welty. Nevertheless, Phillips's South is more fragmented and her narrative is more evasive and varied than any of her Southern predecessors. The South of the twentieth century from the period of Depression until 1972 is reconstructed differently depending on memories and desires of the four members of Hampson family in this novel, either as a place of nostalgia or as the place of trauma or as the place to survive only in memory. The oxymoronic title of the novel, "machine dreams" signifies that dream and memory of the South cannot remain independent in its epistemological entity but exist as a mixture of materiality of every day life in the modern South. The hybridity of this dream and of the South is what defines itself as Southern. Yet Phillips retains feeling of loss and lament enough to create a modern Southern novel rooted in Southern Literature. Thus, the title itself works an antinomic signifier of both the presence and absence of the dream of the South and of Southern Literature.

  • We cloned the complete cDNA of the ${\beta}-bubulin$ from the soft coral, Scleronephthya gracillimum $(K\ddot{u}kenthal)$ (Alcyonacea, Octocorallia, Anthozoa, Cnidaria), via the random sequencing of a cDNA library and the 5'-rapid amplification of cDNA end (RACE) technique. The full-length cDNA of the S. gracillimum ${\beta}-tubulin$ comprised 1541 bp, not including the poly $A^+$ stretch, also contained a complete open reading frame, which codes for a total of 445 amino acids. The amino acid residues 16402 appeared to be in a state of conservation in a variety of animals. Northern blot analysis clearly demonstrated that the sequence we have obtained is, indeed, the full-length cDNA of the ${\beta}-bubulin$ gene in S. gracillimum.

  • This paper is concerned with the following Kirchhoff-Schrödinger-Poisson system $$\begin{cases} -(a+b{\displaystyle\smashmargin{2}\int\nolimits_{\mathbb{R}^3}}{\mid}{\nabla}u{\mid}^2dx){\Delta}u+V(x)u+{\mu}{\phi}u={\lambda}f(x){\mid}u{\mid}^{p-2}u+g(x){\mid}u{\mid}^{p-2}u,&{\text{ in }}{\mathbb{R}}^3,\\-{\Delta}{\phi}={\mu}{\mid}u{\mid}^2,&{\text{ in }}{\mathbb{R}}^3, \end{cases}$$ where a > 0, b, µ ≥ 0, p ∈ (1, 2), q ∈ [4, 6) and λ > 0 is a parameter. Under some suitable assumptions on V (x), f(x) and g(x), we prove that the above system has at least two different nontrivial solutions via the Ekeland's variational principle and the Mountain Pass Theorem in critical point theory. Some recent results from the literature are improved and extended.

  • A steady slot suction near the free-end leading edge of a finite-length square cylinder was used to control its aerodynamic forces and vortex-induced vibration (VIV). The freestream oncoming flow velocity ($U_{\infty}$) was from 3.8 m/s to 12.8 m/s. The width of the tested cylinder d = 40 mm and aspect ratio H/d = 5, where H was the height of the cylinder. The corresponding Reynolds number was from 10,400 to 35,000. The tested suction ratio Q, defined as the ratio of suction velocity ($U_s$) at the slot over the oncoming flow velocity at which the strongest VIV occurs ($U_{\nu}$), ranged from 0 to 3. It was found that the free-end slot suction can effectively attenuate the VIV of a cantilevered square cylinder. In the experiments, the RMS value of the VIV amplitude reduced quickly with Q increasing from 0 to 1, then kept approximately constant for $Q{\geq}1$. The maximum reduction of the VIV occurs at Q = 1, with the vibration amplitude reduced by 92%, relative to the uncontrolled case. Moreover, the overall fluctuation lift of the finite-length square cylinder was also suppressed with the maximum reduction of 87%, which occurred at Q = 1. It was interesting to discover that the free-end shear flow was sensitive to the slot suction near the leading edge. The turbulent kinetic energy (TKE) of the flow over the free end was the highest at Q = 1, which may result in the strongest mixing between the high momentum free-end shear flow and the near wake.

  • Purpose - The Korean government has devised intermodal transportation policies and granted subsidies to shippers and logistics companies that made a conversion of transportation means through the policies. This provides support by expanding the complex uniform railroad transportation and overhauling the deteriorated railroad facilities. As for 2013, however, the freight transportation percentage of railroad was 4.5% in tons and 8.5% in ton kilometers. Meanwhile, since the 1990s, developed countries such as the U.S. and Europe have been trying to expand intermodal freight transport with a legal and institutional support to build a logistics system corresponding with social and economic environmental changes. In this study, I set out to examine the effects of the intermodal freight transport policies in the EU and the U.S., and to explore the direction of setting up a rail intermodal transport system in South Korea. Research design, data, and methodology - The paper used a qualitative research methodology through the literature review. First, was an overview of Intermodal transportation in the EU, U.S. and UN. Second, it describes the development of transport in Europe and the U.S. with particular emphasis on intermodal freight transport. Third, it explores the direction of setting up a intermodal freight transport in South Korea. The last section contains concluding remarks. Results - As for the EU, it has been promoting integration between transport and intermodal logistics network designs while utilizing ITS or ICT and supports for rail freight intermodal by giving reduction to a facilities fee or subsidizing for rail freight in order to minimize the cost of external due to freight transport. On the other hand, as for the U.S., it has been made up of an industrial-led operating project and has been promoting it to improve accessibility between intermodal hubs and cargo terminals through intermodal corridor program, and an intermodal cargo hub access corridor projects, etc. Moreover, it has tried to construct intermodal transport system using ITS or ICT and to remove Barrier. As a result, in these countries, the proportion of intermodal freight transport is going to be the second significant transport compared with rail and maritime transport. An Effective rail intermodal transport system is needed in South Korea, as seen in the case of these countries. In order to achieve this object, the following points are required to establish radical infrastructure policy; diversify investment financing measures taken under public-private partnerships, legal responsibilities, improvement of utilization of existing facilities to connect the railway terminal and truck terminal, and enhancement service competitiveness through providing cargo tracking and security information that combines the ITS and ICT. Conclusions - This study will be used as a basis for policy and support for intermodal freight transport in South Korea. In the future, it is also necessary to examine from the perspective of the shipper companies using the rail intermodal transport, ie, recognition of shipper, needed institutional supports, and transportation demand forecasting and cost-effective analysis of the railway infrastructure systems improvement.

  • The study attempts to investigate the causes of Sino-U.S. trade friction in recent years and provides countermeasures accordingly. The import and export volume of two countries, the product structure of China's export, the 337th Act lawsuits related to China, the industries involved in trade friction, and the G-L Index of Sino-U.S. Products are analyzed in detail. The causes of Sino-US trade frictions are discussed from the aspect of mercantilism and trade protectionism, interest groups and governments' trade policies, Chinese product structure, intellectual property protection in China, and performance of Chinese enterprises in litigation. Based on these, countermeasures are put forward. China needs to implement industrial upgrading, increasing the added value of products, and improving intellectual property protection. A trade friction warning system also needs to be constructed. The Chinese government needs to carry out strategic dialogue and international negotiation.
