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].

This article is focused how the maritime strategy between continental powered country(the Soviet, the China) and maritime powered country(the U.S.) interact with attack and defense theory. We will know, what is the maritime strategy that the U.S. of military superiority has pursued with the point of view of attack, on the other hand, relatively what is the maritime strategy that the Soviet-Sino of military inferiority has pursued with the point of view of defense. In cold war, the Soviet has counteracted to 'blue belt defense' in active defense as to the U.S. 'sea strike' and in post cold war, the China counteract to 'A2/AD' as to the U.S. 'Air-Sea Battle'. The difference between the Soviet-Sino maritime strategy is that the China has emerged the second an economic power and their leadership has a strong's will to strengthen their navy's power. although the U.S. declare the pivot to Asia, the influence on Asia of the U.S. tend to decrease because of sequest. therefore, the China will seek to the more active defense beyond the first island chain. Meanwhile, the U.S. has reinforced of 'hub and spoke strategy' to solidify the U.S. formal allies to band together regional powers and to overcome the A2/AD challenge, the U.S. has been developed that the Air-Sea Battle concept meshes with Washington's 'rebalancing' policy toward the Asia-Pacific as its vital missions to safeguard core island or semi-island allies-namely, Korea and Japan-and crucial sea lanes of communication in the region are conducted mostly from or over the sea.

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.

Korean export of fashion products to the U.S. has fallen off sharply after 2001. Now, Korean fashion companies have to develop higher value-added business. In the U.S., Korean-American fashion companies are taking a primary role in up-stream of the fashion industry. To cut the edge over the U.S. fashion companies, one of the solutions could be to build the business relationship with Korean fashion companies which reflect the recent trend rapidly and have high quality production. On this study, we investigated the marketing strategies of Korean-American fashion companies to seek to start business with Korean fashion companies and make suggestions for Korean fashion companies who want to enter into the U.S. market effectively. To analyze current situation of Korean export to the U.S. and the U.S. fashion industry, we considered various kinds of statistic data, publications and studies. And we performed in-depth interviews with 9 Korean-American fashion companies in LA from $9^{th}$ to $21^{st}$ of July. The results are as follows. first, Korean fashion companies should aim for high-end market with the products of high quality and design. Second, there should be professional agents who manage Korean small-medium fashion companies and connect them with Korean-American fashion companies. Third, Korean fashion companies who want to enter into the retail market of the U.S. have to decide the target market clearly and plan strategic and differentiated merchandising. Fourth, Korean fashion companies can specialize in product developing service like proposing a product or a merchandising line as a package including designs, fabric swatches, trims, production information, etc.

Recently, various industries have appeared which are applied ubiquitous technology. Particularly, health and medical fields, have been focused as future's industry, have been combined with ubiquitous system. This is what we called' u-Health industry. Korean government has encouraged local governments to develop specialized high value-added industries along each local's circumstance. According to the policy, I had an assumption that u-Health industry is Chungbuk province's specialized high value-added industry and studied marketing strategy for the point of penetration into markets. I presented STP strategy for international markets. This strategy referred to developed countries' aging index and based on Modigliani's life cycle hypothesis. Finally, considering none of u-Health has been released, I presented strategies of marketing mix to be utilized when u-Health items march into the markets.

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.

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.
