U.S. lawmakers tend to organize sub-party groups focusing on regions, ideologies, policies, and foreign affairs. Examples include the conservative Freedom Caucus loyal to Trump and the Congressional Black Caucus promoting the interests of African Americans. Then how do these legislative groups affect the making of U.S. foreign policy? Paying special attention to the Korea caucus in U.S. Congress, we have analyzed the sources and processes of congressional caucus and foreign policy and have learned that structures and activities of the caucuses differ from one another. The Korea caucus seems to be a bipartisan group that focuses on issues such as trade, travel, and troubles provoked by Pyongyang. However, the Korea caucus is not really a solid voting bloc for policy alternatives; it is instead more of a constituency-oriented legislative group that prioritizes local interests. This research underscores the need for systematic and comprehensive study of U.S. legislative politics and foreign policy.

So far ubiquitous service (u-service) priority has seldom been empirically examined based on the customer's view. It is usual to prioritize the relative importance of u-service variables by the supplier's intuition and a few specialist's experienced knowledge. Such approaches have the disadvantage that they provide only limited empirical information on the field practices in relation to u-service since customer demand of u-service is poorly defined despite abundant interest in this problem. Therefore, the aim of this research was to develop u-service priority model in the context of multi-criteria framework integrating customer and supplier's view, using high technology acceptance theory as major controlling factors. An important question was how to measure or represent criteria that is important to u-service and should be included in a priority model. The selection criteria for the model variables were derived from high technology acceptance theory and AHP approach through the analysis of frequency count, elimination of overlapping factors and brainstorming with specialists. Daegu showed top-rankings in transportation-aid service, guidance service for the eyesight disabled and u-telematics service. In contrast, disaster prevention service and industrial specialized town service ranked highly in the typical supplier's approach were not a dominant determining factor in the u-service priority. The model identified the fact that typical high priority service in terms of supplier's view did not necessarily accompany the important predictor for the u-service priority.

This paper is concerned with the existence of positive solutions of the nonlinear Neumann boundary value problems $$\{u^{{\prime}{\prime}}+a(t)u={\lambda}b(t)f(u),\;t{\in}(0,1),\\u^{\prime}(0)=u^{\prime}(1)=0$$, where $a,b{\in}C[0,1]$ with $a(t)>0,\;b(t){\geq}0$ and the Green's function of the linear problem $$\{u^{{\prime}{\prime}}+a(t)u=0,\;t{\in}(0,1),\\u^{\prime}(0)=u^{\prime}(1)=0$$ may change its sign on $[0,1]{\times}[0,1]$. Our analysis relies on the Leray-Schauder fixed point theorem.

Korean businesses, and their legal representatives, have observed the improvements of enforcement of commercial judgments through arbitration over traditional collections litigation in U.S. Courts-due to quicker proceedings, exceptional cost savings and more predictable outcomes-in attaching assets within U.S. jurisdictions. But how are the 2016 interim measures implemented by the Arbitration Act of Korea utilized to avoid jurisdictional and procedure pitfalls of enforcement proceedings in the Federal Courts of the United States? Authors examine the necessary prerequisites of the U.S. Federal Arbitration Act as adopted through the New York Convention, to which Korea and the U.S. are signatories, as distinguished from the Panama Convention. Five common U.S. arbitration institutions address U.S. "domestic" disputes, preempting U.S. state law arbitrations, while this article focuses on U.S. enforcement of "international" arbitration awards. Seeking U.S. recognition and enforcement of Korean arbitral awards necessitates avoiding common defenses involving due process, public policy or documentary formality challenges. Provisional and conservatory injunctive relief measures are explored. A variety of U.S. cases involving Korean litigants are examined to illustrate the legal challenges involving non?domestic arbitral awards, foreign arbitral awards and injunctive relief. Suggestions aimed toward further research are focused on typical Korean business needs such as motions to confirm foreign arbitration awards, enforce such awards or motions to compel arbitration.

We study the Dirichlet problem for the degenerate nonlocal parabolic equation u_t - a(||∇u||²_L²(Ω))∆u = C_b ||u||^β_L²(Ω) |u|^q(x,t)-2 u log |u| + f in Q_T, where Q_T := Ω × (0, T), T > 0, Ω ⊂ ℝ^N, N ≥ 2, is a bounded domain with a sufficiently smooth boundary, q(x, t) is a measurable function in Q_T with values in an interval [q^-, q⁺] ⊂ (1, ∞) and the diffusion coefficient a(·) is a continuous function defined on ℝ₊. It is assumed that a(s) → 0 or a(s) → ∞ as s → 0⁺, therefore the equation degenerates or becomes singular as ||∇u(t)||2 → 0. For both cases, we show that under appropriate conditions on a, β, q, f the problem has a global in time strong solution which possesses the following global regularity property: ∆u ∈ L²(Q_T) and a(||∇u||²_L²(Ω))∆u ∈ L²(Q_T ).

Minimal s-Urysohn and minimal s-regular spaces are studied. An s-Urysohn (respectively, s-regular) space (X, $\mathfrak{T}$) is said to be minimal s-Urysohn (respectively, minimal s-regular) if for no topology $\mathfrak{T}^{\prime}$ on X which is strictly weaker than $\mathfrak{T}$, (X, $\mathfrak{T}^{\prime}$) is s-Urysohn (respectively s-regular). Several characterizations and other related properties of these classes of spaces have been obtained. The present paper is a study of minimal P-spaces where P refers to the property of being an s-Urysohn space or an s-regular space. A P-space (X, $\mathfrak{T}$) is said to be minimal P if for no topology $\mathfrak{T}^{\prime}$ on X such that $\mathfrak{T}^{\prime}$ is strictly weaker than $\mathfrak{T}$, (X, $\mathfrak{T}^{\prime}$) has the property P. A space X is said to be s-Urysohn [2] if for any two distinct points x and y of X there exist semi-open set U and V containing x and y respectively such that $clU{\bigcap}clV={\phi}$, where clU denotes the closure of U. A space X is said to be s-regular [6] if for any point x and a closed set F not containing x there exist disjoint semi-open sets U and V such that $x{\in}U$ and $F{\subseteq}V$. Throughout the paper the spaces are assumed to be Hausdorff.

This study was designed to investigate the teacher belief related to children literacy between Korea and U.S.A. using the quantitative research. The instrument for this study was constructed with 35 Likert-scaled questions in a survey questionnaire. Additionally, this study found that there existed significant difference with 20 questions between Korea and U.S.A. based on teacher's belief related to children's literacy and relationship between teachers who learns the whole language and the scores of teacher beliefs about literacy in the research. Seventy-six teachers who work at early childhood settings in State College, Bellefonte, Pleasant Gap, and Lemont in Central Pennsylvania participated in U.S.A. and ninety-one teachers who work at early childhood setting in Seoul and Pusan in Korea participated in this survey. This research has provided a framework for investigating the teacher beliefs about teaching literacy in order to discover the whole language effect on the system of teacher beliefs. This study focused on teacher beliefs towards the whole language approach between Korea and U.S.A.

Technological innovations can be protected by patents, and patent applications are filed in various patent offices around the world including the United States Patent and Trademark Office (USPTO). Recently, the U.S. exportation of artificial intelligence and internet of things patents in the form of foreign sales of articles embodying U.S. patents and international technology licenses has grown substantially. However, due to the U.S. Supreme Court's Lexmark decision reconfirming an international patent exhaustion doctrine, the asian or korean importers importing such U.S. goods embodying U.S. patents do not have to worry about patent infringement liability, even when they try to resell the patented goods to the third parties. KCAB can play a substantial role in resolving such patent disputes due to qualified expert arbitrators and the International Rules of KCAB which ensure impartiality and independence of the arbitrators.

This study has analyzed the international trade flow of medical devices in Korea, China, and U.S. more theoretically and systematically through a mutual connection of the medical device export structure of Korea and the import structure of China and U.S. organically, with an intensity approach on the bilateral international trade flow. Also, it is meaningful to find a solution to boost exports of Korea to China and U.S.. Therefore in this study, we recognize the importance of the medical device market in China and U.S., which is the main competition for Korea and its market, and look into the trade situation of these three countries. We also look into the relative market stream and the trade intensity of the main medical devices in Korea, China and U.S., and seek measures for the steady growth of the medical device market in these three countries.

Sun Tzu once clarified that "One who knows the enemy and knows himself will not be endangered in a hundred engagements, " while Clausewitz explained that "A victory will be guaranteed for one who can overcome 'fog and friction' at a battlefield." Now the U.S. is striving hard to develop an American version of RMA (Revolution in Military Affairs)/MTR (Military Technical Revolution) by utilizing its rapidly emerging information technology in the information age. The U.S. firmly believes that its RMA/MTR with less defense expenditure can provide all combat players in the battlespace with "dominant battle awareness, " by which no nation will be able to challenge U.S. military superiority. In this paper, the recent efforts of the U.S. Armed Forces on RMA/MTR will be briefly introduced, some lessons and expertises from the U.S. RMA/MTR are extracted, and, in this regard, several suggestions are provided for the progress of the ROK Armed Forces.gress of the ROK Armed Forces.
