  • The purpose of this article is to introduce the gifted education of mathematics in Korea. We first discuss what is going on in Korea for mathematics education for gifted students. The curriculums for the institutes for gifted education are mentioned. Some focus of this article is proposing some teaching materials that are actively utilizing many basic concents of cryptography and super-string theory, along with careful use of calculators and computers. Many of the materials haven been designed with problem-posing approach on through invoking the cognitive conflict.

  • In this article, the author's intent is to begin a conversation centered on the question: How was the integration of digital technology into elementary mathematics classrooms framed? In the first part of the discussion, the author provides a historical perspective of the development of theoretical perspectives of the integration of digital technology in learning mathematics. Then, the author describes three theoretical perspectives of the role of digital technology in mathematics education: microworlds, instrumental genesis, and semiotic mediation. Last, based on three different theoretical perspectives, the author concludes the article by asking the reader to think differently.

  • In the Chosun Dynasty Nam, Byung-Gil(another name is Nam, Sang-Gil alias Won-Sang; 1820-1869) made a research comparing Chinese traditional mathematics with western mathematics, which missionaries who came to China at the end of Ming Dynasty introduced. He particularly studied fundamental differences between Chinese and western methods to solve algebraic equations. He wrote an article "Moo-Ee-Hae", in which he insisted that the two methods are eventually same though they are different in the고 expressions. His article has big significance as the first mathematic paper in the history of Korean mathematics.thematics.

  • Shape memory alloys(SMAs) have revolutionized the material engineering sciences as they exhibit exclusive features i.e. shape memory effect(SME) and super-elasticity. SMAs are those alloys that when deform return to their predeformed shape upon heating, they also restore their original shape by removing the load. Research on properties of newly advent of several types of ferrous based shape memory alloys(Fe-SMAs), shows that they have immense potential to be the counterpart of Nitinol(NiTi-SMA). These Fe-SMAs have been used and found to be effective because of their low cost, high cold workability, good weldability & excellent characteristics comparing with Nitinol(high processing cost and low cold workability) SMAs. Some of the Fe-SMAs show super-elasticity. Fe-SMAs, especially Fe-Mn-Si alloys have an immense potential for civil engineering structures because of its unique properties e.g. two-way shape memory effect, super elasticity and shape memory effect as well as due to its low cost, high elastic stiffness and wide transformation hysteresis comparative to Nitinol. Further research is being conducted on SMAs to improve and impinge better attributes by improving the material compositions, quantifying the SMA phase transition temperature etc. In this research pre-existing Fe-SMAs are categorised and collected in a tabulated form. An analysis is performed that which category is mostly available. Last 50 years data of Fe-SMA publications and US Patents is collected to show its importance in terms of increasing research on such type of alloys to invent different compositions and applications. This data is analysed as per different year groups during last 50 years and it was analysed as per whether the keywords exist in title of an article or anywhere in the article. It was found that different keywords related to Fe-SMAs/categories of Fe-SMAs, almost don't exist in the title of articles. However, these keywords related to Fe-SMAs/categories of Fe-SMAs, exist inside the article but still there are not too many publications related to Fe-SMAs/categories of Fe-SMAs.

  • Objective: Pharmacopuncture, a new therapy in traditional medicine, has attracted significant attention since its introduction to the Western world. This short review article employs a database analysis to examine the profile of publication activity related to pharmacopuncture. Methods: Three databases were searched: PubMed, Embase, and Cochrane. About 300 papers related to the topic "pharmacopuncture" were found in these three most-commonly-used databases. Results: Fourteen papers are described in detail and are discussed in the context of the research performed at the Medical University of Graz, especially by the Frank Bahr Research Group "Auriculomedicine and Pharmacopuncture." Conclusion: High-tech research methods concerning future pharmacopuncture studies are briefly discussed.

  • The article surveys the technique and characteristics of contemporary fashion exhibitions in terms of fashion museography and fashion curation. The article reviewed both a literature study on the history of fashion exhibition focused on the display technique as well as a case study of domestic and international contemporary fashion exhibitions. The results of the article is as follows. Fashion brand exhibitions are about building competitive business advantage by planning differentiated contents. It gives viewers a brand fantasy and increases brand loyalty. This type mainly displays the latest collections on the commercial purpose as well as uses diverse mediums and high technology to make a spectacular space that provides an immersive experience to the viewer. Second, the museum fashion exhibition focuses on the roles of fashion in terms of social, cultural and artistic aspects that also focus on public education. The presentation technique emphasizes careful collection conservation rather than celebrate fashion business. The article is to encourage a further scholar discourse of fashion curatorial practice and theory.

  • The large increase in RTAs since the late 1980's has challenged the foundations of the multilateral trading system, and thereby has become an axis in the GATT/WTOsystem.While RTAs can be seen to be contradictory to the overall aim of the WTO, they were allowed for in Article XXIV of GATT conditional to certain provision. The failure of compliance and subsequently enforcement of these provisions could be seen as a serious flaw of Article XXIV since the inception of GATT system. Many elements of GATT Article XXIV are not clear and thus lead to divergent interpretations of its disciplines. This considerable divergence in opinions arise from both ambiguities throughout the provisions under GATT Article XXIV. In this regard, both economic and legal work is required to keep up with constantly changing nature of the world trading system. Further, global efforts are required to resolve another teething issue of WTO's problematic institutional framework on GATT/WTO's oversight and surveillance of RTAs. and thereby strengthen the multilateral trading system. Needless to say, theGATT/WTOframework has been essential in paving the way for RTAs while ensuring a more multilateral and liberal trading system. Consequently, global efforts should be made to restructure the WTO for the renewed multilateral trade liberalization in the GATT/WTO.

  • This article explored the bank's responsibilities in electronic payment system between Korea and U.S.A. In order to complete my research object, I used Article 4A of the U.C.C. and EFTA of 1978 and by Electronic Financial Transaction Act of Korea as a analytic instruments. I also adapted America's various regulations to regulate concerned parties(banks). The system of this article is going to display as fellows; First, I presented recent trend and legal stabilities of electronic payment in this article. Second, I focuses on the allocation of risk of loss caused by ambiguous term in payment orders that do not express the subjective intention of the senders. I also did analyze the solution procession of error occurring in course of send of payment order. Third, In any action which involves a customers's liability for an unauthorized electronic fund transfer, the burden of proof is upon the financial institution to show that the electronic fund transfer was authorized. Forth, Customers have to report the error and unauthorized electronic fund transfer after awaring of it. Then bank will be liable for such a unauthorized electronic fund transfer. But If customer's failure to report, the bank has exemptions. Lastly, In order to prevent or detect the unauthorized electronic fund transfer, bank will agree with custom to establish a commercially reasonable security procedure, while bank has duties to notify in order to decrease the loss resulted from unauthorized payment order in korea law.
