The three main purposes of this paper are to (1) identify critical success factors(CSFs) for electronic commerce(EC), (2) investigate the explanatory power of these CSFs on firm performance, and (3) compare differences in evaluating CSFs and explaining impact of CSFs on performance among Korea, Japan, and U.S.A. EC firms. Through a literature review and interviews with managers in EC firms, a list of 16 CSFs consisting of 111 items was compiled. In the second stage, questionnaires were administered to managers of EC companies in Seoul, Korea, Tokyo, Japan, and Texas, U.S.A. Survey results show that CSFs have very significant explanatory power for firm performance in Korea, Japan, and U.S.A. While security, privacy, technical expertise, information about goods/services, and variety of goods/services are the most explanatory CSFs in Korea and Japan, evaluation of EC operations, technical expertise, and ease of use show most explanatory power in U.S.A. In general, respondents in Korean and Japan evaluate CSFs quite differently compared to U.S.A counterparts.

이 연구는 1950년대 미국정부가 문화냉전의 와중에서 공공외교의 일환으로 해외에서 수행했던 도서 프로그램의 전체적인 윤곽을 살펴본 후, 한국에서 시행한 도서번역 사업의 전개 과정과 목적 및 내용을 분석하고, 사업의 성과와 의미를 검토하였다. 분석의 결과로, 한국에서의 미국 도서번역 사업은 미군정기부터 극히 미진한 수준에서 시작되었지만, 한국전쟁을 거치면서 본격화되어 1950년대 후반에 최고조에 도달했던 것으로 밝혀졌다. 1950년대 미국 국무성과 대외공보국(USIA)의 지침에 따라 주한 미공보원(USIS)이 수행했던 도서번역 사업의 목적은 시기에 따라 개별적인 비중이 변화되기는 했어도, 대체로 미국의 자유민주주의와 자본주의 체제의 우월성을 강조하고, 공산주의 사회의 부조리와 모순을 비판하며, 미국의 외교 정책에 대한 이해를 제고하고, 예술 문학 과학 부문에서의 미국의 성취를 전파하려 했던 것으로 확인되었다. 특히 번역 도서를 선정할 때 미국의 대외정책과 모순되거나 국가적 이미지를 훼손할 가능성이 있는 도서는 철저히 배제하였고, 미국정부의 공보정책에 기여할 것으로 판단되는 소수의 한국인 저작물에 대해서는 지원을 아끼지 않았으며, 도서번역 사업의 효과를 극대화하기 위해 일본어 번역서를 활용하는 것도 마다하지 않았다. 이러한 미국정부의 도서번역 사업은 한국이 해방과 분단으로 겪게 된 지식과 정보의 공백 상태를 극복하는 데 일정하게 기여했다고 평가할 수 있지만, 다른 한편으로 미국정부의 정책적 기준에 따른 도서 선정으로 말미암아 한국인들의 대미 인식이나 세계정세 판단에 왜곡을 초래했을 수도 있다고 생각된다.

Let $N{\geq}1$ and p > 1. Let ${\Omega}$ be a domain of $\mathbb{R}^N$. In this article we shall establish Kato's inequalities for quasilinear degenerate elliptic operators of the form $A_pu$ = divA(x,$\nabla$u) for $u{\in}K_p({\Omega})$, ), where $K_p({\Omega})$ is an admissible class and $A(x,\xi)\;:\;{\Omega}{\times}\mathbb{R}^N{\rightarrow}\mathbb{R}^N$ is a mapping satisfying some structural conditions. If p = 2 for example, then we have $K_2({\Omega})\;= \;\{u\;{\in}\;L_{loc}^1({\Omega})\;:\;\partial_ju,\;\partial_{j,k}^2u\;{\in}\;L_{loc}^1({\Omega})\;for\;j,k\;=\;1,2,{\cdots},N\}$. Then we shall prove that $A_p{\mid}u{\mid}\;\geq$ (sgn u) $A_pu$ and $A_pu^+\;\geq\;(sgn^+u)^{p-1}\;A_pu$ in D'(${\Omega}$) with $u\;\in\;K_p({\Omega})$. These inequalities are called Kato's inequalities provided that p = 2. The class of operators $A_p$ contains the so-called p-harmonic operators $L_p\;=\;div(\mid{{\nabla}u{\mid}^{p-2}{\nabla}u)$ for $A(x,\xi)={\mid}\xi{\mid}^{p-2}\xi$.

In this paper, we define the sequence spaces: $[V,{\lambda},f,p]_0({\Delta}^r,E,u),\;[V,{\lambda},f,p]_1({\Delta}^r,E,u),\;[V,{\lambda},f,p]_{\infty}({\Delta}^r,E,u),\;S_{\lambda}({\Delta}^r,E,u),\;and\;S_{{\lambda}0}({\Delta}^r,E,u)$, where E is any Banach space, and u = ($u_k$) be any sequence such that $u_k\;{\neq}\;0$ for any k , examine them and give various properties and inclusion relations on these spaces. We also show that the space $S_{\lambda}({\Delta}^r, E, u)$ may be represented as a $[V,{\lambda}, f, p]_1({\Delta}^r, E, u)$ space. These are generalizations of those defined and studied by M. Et., Y. Altin and H. Altinok [7].

본 연구에서는 배추김치를 종자별, 부위별, 저장조건별 유리당, vitamin C, amino acids의 함량을 분석하고 변화 경향을 조사하여 보았으며 vitamin C의 전구물질인 methionine과의 상관관계에 대한 연구를 수행하였다. 유리당의 경우 core> middle> outward 부위 순으로 높은 함량을 나타냈으며, midrib 부위의 함량이 높은 것으로 조사되었다. Vitamin U의 경우55일 배추 outward leaf 부위에서 함량이 가장 높았으며 저장기간이 증가 할수록 함량이 증가하는 경향을 나타내었다. 유리 amino acids의 함량은 vitamin U와 같이 outward leaf 부위가 전반적으로 높았으며 특히 threonine, alanine, proline이 가장 풍부한 아미노산으로 조사되었다. Vitamin U의 전구물질인 methionine의 함량은 부위별, 저장조건별 큰 차이를 보여주었으나, vitamin U 함량에 미치는 영향에 대한 뚜렷한 상관관계는 보이지 않았다.

This paper aims to use crossover analysis to uncover similarities and differences between the U.S-Japan relationship in the World War II era and the modern U.S-China relationship, and to forecast the possibility of the outbreak of war between U.S and China by applying the steps to war theory. The steps to war theory argues that the probability of the outbreak of war between two states within five years would approach 90 percent, if they have ongoing territorial dispute, alliance, rivalry, and arms race. The comparison exposes some similarities with the territorial dispute, alliance, rivalry, but reveals dissimilarities with arms race. U.S-Japan relationship in the World War II era had the arms race, which does not exist the modern U.S-China Relationship. The result of comparison is that the probability for the Outbreak of War between U.S and China correspond to third stage(Risk Level). it means that the probability for the Outbreak of War between U.S and China is 55%. But, There are four elements(① Perception of Leader ② Mutual dependence of economy ③ Possession of nuclear weapon ④ Ravages of war) that reduce the probability for the Outbreak of War. Considering the four elements, the probability for the Outbreak of War between U.S and China is a slim chance. But the probability for the Outbreak of War between U.S and China is excluded because of territorial dispute, alliance, rivalry. So, This paper suggests three points.(① Developing military options ② Reducing the misconception of intend, ③ Promoting navy exchanges) to prevent of Outbreak of War.

Korea-China FTA and Korea-U.S. FTA are the most significant FTA in volume and economic effect for Korea's perspective. Developed countries have dealt with environmental issues one of the main issues in FTA negotiation, while developing countries have been reluctant to it. Both Korea-China FTA and Korea-U.S. FTA have separate environment chapter respectively. A separate environment chapter was firstly introduced in Korea-U.S. for Korea's perspective. Both environment chapters provide high level of environment protection, recognition of multilateral environmental agreements, enforcement of environmental laws, and environmental cooperation. Both environment chapters require that each party make effort to improve environmental laws and measures. Korea-China FTA provides establishment a "Committee on Environment and Trade", and Korea-U.S. FTA provides establishment a "Environment Council" to oversee the implementation of environment clauses. Korea-China FTA and Korea-U.S. FTA have very similar provisions on environment and trade, and are expected to contribute to enhancing environment protection. However, a lot of provisions are somewhat declaratory rather than mandatory. Therefore, further environmental cooperation is encouraged to achieve the goals and objectives of the environment clauses and FTA.

This paper examines how a Korean automobile firm price-discriminates between the Korean and the U.S. markets. We argue that a Korean automobile firm's pricing behavior depends on the differences in price elasticity over the segmented markets between the countries. Our findings are that differences in price elasticity may help explain why a medium-class car's price is higher in Korea than that in the U.S. while a small-sized car's price is higher in the U.S. than in Korea, which implies that a Korean automobile firm $3^{rd}$ degree price-discriminates on the same or similar products between Korea and the U.S. This type of $3^{rd}$ degree price discrimination differs from a typical home-bias effect (charging higher prices to domestic consumers) because a small-sized car which is produced domestically sells at higher price abroad. This finding can be added as a source that violates the law of one price.

The United States understood the fostering of pro-U.S. elites in "free world" countries as an important Cold War weapon. From 1954 to 1962, the U.S provided considerable assistance to Seoul National University (SNU) for its postwar rehabilitation and future development in terms of repair and construction of campus buildings, equipment and book purchases, and faculty exchanges. With the aid of this educational assistance project widely known as the Minnesota Project, SNU was reborn with an academic orientation to the U.S., separating itself from the Japanese education that was its origin. This study argues that the Minnesota Project played an important role in crafting SNU's architecture program and the exchange program's recipients as key "knowledge brokers." For individual trainees, experience in the U.S., as opposed to a backwards situation in their homeland, had allowed them to recognize the U.S. as an ideal source of knowledge. Since the Minnesota Project, SNU's Architectural Engineering Department was filled with faculty members who had trained or studied in the U.S., which became a significant distinction of SNU's architecture program in sharp contrast to its counterparts at Hanyang University and Hongik University where most of the faculty members studied in Japan during the Japanese colonial period. As many graduates of SNU had been appointed as faculty members in newly-founded architecture programs in South Korea, a hierarchical diffusion path had emerged in architectural education that led from SNU to other school's architecture programs, with the U.S. at the apex. The legacy of the Minnesota Project extended over the next few decades, in which studying architecture in the U.S. was recognized as a shortcut to success in the field.

We introduce the concepts of double bitopological spaces as a generalization of intuitionistic fuzzy topological spaces in $\check{S}$ostak's sense and Kandil's fuzzy bitopological spaces. Also we introduce the concept of (${\tau}^{{\mu}{\gamma}}$, $U^{{\mu}{\gamma}}$)-double (r, s)(u, v)-semiopen sets and double pairwise (r, s)(u, v)-semicontinuous mappings in double bitopological spaces and investigate some of their characteristic properties.
