  • For the past 66 years, the Korea-U.S. alliance has been a typical asymmetric alliance in which the U.S. supports South Korea's security during the Cold War and South Korea gives some of its policy autonomy to the U.S. But Lee Myung-bak government military alliance the 'comprehensive strategic alliance' of the character, 'value of alliance', Park Geun-hye ' a global, 'Frontier of cooperation', the government.'reciprocal, comprehensive alliance' Moon Jae-in, the government and partnerships developed with ' euroui the development of national security strategy said. The purpose of this study is to explore ways to build a reciprocal and comprehensive Korea-U.S. alliance for the development of the Korea-U.S. alliance policy in order to ensure South Korea's policy autonomy following changes in the Trump administration's alliance policy. The results of the research show the need for Korea to participate in the U.S.-led 'India-Pacific Strategy' continue diplomatic efforts for the mutual economic benefits of the two countries and strengthen public diplomacy in order to build the Korea-U.S. alliance in a reciprocal and comprehensive manner.

  • Background: N-myc downstream-regulated gene 2 (NDRG2), a member of a newly described family of differentiation-related genes, has been characterized as a regulator of dendritic cells. However, the role of NDRG2 on the expression and activation of transcription factors in blood cells remains poorly understood. In this study, we investigated the effects of NDRG2 overexpression on GATA-1 expression in PMAstimulated U937 cells. Methods: We generated NDRG2-overexpressing U937 cell line (U937-NDRG2) and treated the cells with PMA to investigate the role of NDRG2 on GATA-1 expression. Results: NDRG2 overexpression in U937 cells significantly induced GATA-1 expression in response to PMA stimulation. Interestingly, JAK2/STAT and BMP-4/Smad pathways associated with the induction of GATA-1 were activated in PMA-stimulated U937-NDRG2 cells. We found that the inhibition of JAK2 activation, but not of BMP-4/Smad signaling, can elicit a decrease of PMA-induced GATA-1 expression in U937-NDRG2 cells. Conclusion: The results reveal that NDRG2 promotes the expression of GATA-1 through activation of the JAK2/STAT pathway, but not through the regulation of the BMP-4/Smad pathway in U937 cells. Our findings further suggest that NDRG2 may play a role as a regulator of erythrocyte and megakaryocyte differentiation during hematopoiesis.

  • Owing to a tremendous progress of information technology we have faced a great change of a society. This change has happened to almost all of a society. As a result intangible goods are also included as a major concern in international trade. We may say U.S. is one of the countries transaction of software is the most flourishing. I have tried to classified the cases of software transaction in U.S. into five groups. As a result I have known the UCC had been applied to the almost transaction of standard software. However UCC had not been applied to custom software and data processing. In these days UCITA which is very similar to a previous proposal UCC 2B has been presented. This is a contract law that would apply to computer software, multimedia products, and databases. It has been designed to create a uniform commercial contract law for those products. Now therefore we should make observation of a tendency about transaction of software in U.S. The reason is that we pay attention to the symbol and dormant power of U.S. in international trade.

  • Since 1855, the federal courts of the United States have been empowered to assist in the gathering of evidence for use before foreign tribunals. Today, the source of that authority is 28 U.S.C. ${\S}1782$ which permits the courts to order a person "to give [ ] testimony... or to produce a document ... for use in a proceeding in a foreign or international tribunal${\cdots}$ ." It was generally assumed, until the United States Supreme Court's decision of Intel Corp. v. Advanced Micro Devices, Inc. in 2004, that arbitration tribunals were not "foreign tribunals" for purposes of 28 U.S.C. ${\S}1782$. While the issue in Intel did not involve an arbitration tribunal, a statement by the Supreme Court in dicta has called into question the exact parameters of the words "foreign tribunal," resulting in a split of opinion among the federal courts of the United States. This article explores the legislative history of 28 U.S.C. ${\S}1782$, examines the United States Supreme Court decision in Intel, and discusses the split among the courts of the United States regarding the interpretation of "foreign tribunal." The article further surveys emerging issues: is an arbitration tribunal in a case involving foreign parties and seated in the United States a "foreign tribunal"; does agreeing to the use of the IBA Rules on the Taking of Evidence in International Arbitration circumscribe the use of 28 U.S.C. ${\S}1782$; can a party be ordered to produce documents located outside the United States; and is there a role for judicial estoppel in determining whether an application pursuant to 28 U.S.C. ${\S}1782$ should be granted?

  • We find the distributional solutions of the Wilson's functional equations $$u{\circ}T+u{\circ}T^{\sigma}-2u{\otimes}v=0,\\u{\circ}T+u{\circ}T^{\sigma}-2v{\otimes}u=0,$$ where $u,v{\in}{\mathcal{D}}^{\prime}({\mathbb{R}}^n)$, the space of Schwartz distributions, T(x, y) = x + y, $T^{\sigma}(x,y)=x+{\sigma}y$, $x,y{\in}{\mathbb{R}}^n$, ${\sigma}$ an involution, and ${\circ}$, ${\otimes}$ are pullback and tensor product of distributions, respectively. As a consequence, we solve the $Erd{\ddot{o}}s$' problem for the Wilson's functional equations in the class of locally integrable functions. We also consider the Ulam-Hyers stability of the classical Wilson's functional equations $$f(x+y)+f(x+{\sigma}y)=2f(x)g(y),\\f(x+y)+f(x+{\sigma}y)=2g(x)f(y)$$ in the class of Lebesgue measurable functions.

  • The purpose of this paper is to review China's perception on the U.S. power after the global financial crisis. Although economic power of U.S. was declined by the global financial crisis, U.S. hegemony in the international order still maintains. Gap of national power between U.S. and China may be narrow because of decline of U.S. economic power. It can be predicted China will push a policy that secures an initiative of reform in the global monetary system and is going to take a more cooperative policy without U.S. hegemony power harming China's core interests.

  • We investigate the relationships between the space X and the hyperspaces concerning admissibility and connectedness im kleinen. The following results are obtained: Let X be a Hausdorff continuum, and let A, $B{\in}C(X)$ with $A{\subset}B$. (1) If X is c.i.k. at A, then X is c.i.k. at B if and only if B is admissible. (2) If A is admissible and C(X) is c.i.k. at A, then for each open set U containing A there is a continuum K and a neighborhood V of A such that $V{\subset}IntK{\subset}K{\subset}U$. (3) If for each open subset U of X containing A, there is a continuum B in C(X) such that $A{\subset}B{\subset}U$ and X is c.i.k. at B, then X is c.i.k. at A. (4) If X is not c.i.k. at a point x of X, then there is an open set U containing x and there is a sequence $\{S_i\}^{\infty}_{i=1}$ of components of $\bar{U}$ such that $S_i{\longrightarrow}S$ where S is a nondegenerate continuum containing the point x and $S_i{\cap}S={\emptyset}$ for each i = 1, 2, ${\cdots}$.

  • The recent issue on the withdrawal of U.S. Forces from Korea Suggests an Urgency of Self Defense of Korea. The expected huge defense budget and her armed forces create a need for an operational analysis. It is shown through a statistical analysis what some of the opportunity costs of defense spending have been. Some evidences about what some of the economy sacrifice if defense spending rises have been analyzed to provide executive departments with a quantitative basis for decisions. The Korea-U.S. alliance is discussed in view of the developmental effects of U.S. aids and deterrent effects of U.S.F.K.
