  • Combining recent advances in causal flows with time series analysis, relationships among eight North American natural gas spot market prices are examined. Results indicate that price discovery tends to occur in excess demand regions and move to excess supply regions. Across North America, the U.S. Midwest region represented by Chicago spot market is the most important market for price discovery. The Ellisburg-Leidy Hub in Pennsylvania is important in price discovery, especially for markets in the eastern two-thirds of the U.S. Malin Hub in Oregon is important for the western markets including the AECO Hub in Alberta, Canada.

  • 본 논문에서는 내장된 수동형 트리플렉서와 듀얼 밴드/트라이모드 RF 모듈을 PCB에 내장시켜서 북미향 CDMA용 부품으로 제작하였다. 수동형 트리플렉서는 모든 수동 소자들을 다층 PCB 기판 안에 내장시키고 그 위에 GPS용 SAW 대역통과필터를 이용하여 설계 및 제작하였다. 8개의 인덕터와 커패시터로 이루어진 수동 회로는 다이플렉서와 병렬 공진기, 임피던스 매칭 회로로 구성되어 있다. CDMA용 듀얼밴드/트라이모드 RF 모듈은 트리플렉서와 CDMA, PCS용 듀플렉서를 테스트 보드 위에 조합하여 제작하였다. 측정된 주파수 특성들은 시뮬레이션 값과 비교적 일치하였다. 트리플렉서와 듀얼 밴드/트라이모드 RF 모듈은 각기 $3{\times}4mm^2$와 ${7\times}7mm^2$의 작은 크기였다. 설계 및 제작된 소자들은 고성능과 경박단소화, 저가화 등의 이점이 있기 때문에, 북미향 CDMA용 단말기의 응용부품에 적용될 수 있을 것으로 예상된다.

  • The purpose of this article is to critically read Globalizing Borderlands Studies in Europe and North America to examine trends in border studies conducted so far in Europe and North America and to discuss the expandability and limitations of the narrative. It introduces a variety of case studies covering the borderlands of Europe and North America from ancient to modern times. It consists of a total of 10 chapters, in addition to the introduction chapter to clarify the purpose and definition of the collaboration and the short conclusion chapter on the prospects for the future of borderlands studies. This volume has some important implications for current borderland research in two main respects. First, it can introduce us we the areas and targets that the leading researchers from European and North American academia (usually the United States') have paid attention to. It also examines the current status of borderland research and predicts whether it will be possible to study various border areas where exist in other regions (especially in Asia) based on accumulating academic achievements, as well as the possibility of expansion of so-called 'globalization'. Second, it introduces the borderland as a conceptual space, beyond the border area as a physical space that is commonly thought of when it comes to 'border'. Cases of "conceptual borderlands" can be applied to a number of topics ranging from an individual's identities to the methods of governance, religions, economies, social institutions, families, labor issues, public health services and gender issues. There are, however, also some questions to be noted in the volume: the lack of consistent use of terminology, which can be considered general problems of collaboration studies; the fact that the authors still tend to understand borderlands within the imperialist discourse, perhaps because of their academic background is situated mainly in Europe and North America; the borderlands cases described here as the areas of conflict and struggle only. Nevertheless, the book is of significance in that it suggests a possibility of various borderlands studies and helps us to have better understanding of the current geopolitical situation imposed on the Korean Peninsula, which is located on the borderland between the continental and maritime powers.
