고상 반응법을 이용하여 $La_{0.7}Sr_{0.3}Ga_{0.6}Fe_{0.4}O_{3-\delta}$ 분말을 합성하고 소결하여 혼합전도성 분리막을 제조하였다. 제조된 분리막들은 페롭스카이트 단일상 결정구조를 나타내었으며, $95\%$, 이상의 상대밀도를 나타내었다. 산소이온 변환 능력을 향상시키기 위해 $La_{0.7}Sr_{0.3}Ga_{0.6}Fe_{0.4}O_{3-\delta}$의 양 표면에 $La_{0.6}Sr_{0.4}CoO_{3-\delta}$ paste를 스크린 프린팅 방법으로 코팅한 결과, 코팅되지 않은 분리막에 비해 산소투과 유속이 크게 증가하여 $950^{\circ}C,\; {\Delta}P_{o_2}=0.21 atm$에서 약 $0.5ml/min{\cdot}cm^2$의 값을 나타내었다. 이러한 산소투과 유속은 표면 코팅층이 다공성일수록, $La_{0.7}Sr_{0.3}Ga_{0.6}Fe_{0.4}O_{3-\delta}$의 결정립 크기가 증가할수록 증가하는 경향을 나타내었다. 제조된 디스크 형상의 소결체를 이용하여 $950^{\circ}C$에서 메탄부분산화반응을 행한 결과 $40\%$ 이상의 메탄전환율과 합성가스의 수율을 얻을 수 있었으며, CO의 선택도는 $100\%$를 나타내었다 또한, $950^{\circ}C$의 메탄분위기에서 600시간의 장기부분산화반응을 통해 상의 안정성을 확인하였다. We fabricated mixed ionic-electronic conducting membranes, $CH_4\;Using\;{0.7}Sr_{0.3}Ga_{0.6}Fe_{0.4}O_{3-\delta}$, by solid state reaction method for solid oxide fuel cell. The membranes consisted of single perovskite phase and exhibited high relative density, $>95\%$. We coated $La_{0.6}Sr_{0.4}CoO_{3-\delta}$ layer using screen printing method in order to improve surface reactivity of the $La_{0.7}Sr_{0.3}Ga_{0.6}Fe_{0.4}O_{3-\delta}$. As a result, the oxygen permeation flux of the coated $La_{0.7}Sr_{0.3}Ga_{0.6}Fe_{0.4}O_{3-\delta}$ showed higher value, $0.5ml/min{\cdot}cm^2\;at\;950^{\circ}C$ than the uncoated one. Higher oxygen permeation was observed in the porously coated Lao $La_{0.7}Sr_{0.3}Ga_{0.6}Fe_{0.4}O_{3-\delta}$membranes with larger grain sizes. Syngas, $CO+H_2$, was successfully obtained from methane gas, $CH_4$, using the $La_{0.6}Sr_{0.4}CoO_{3-\delta}$ coated $La_{0.7}Sr_{0.3}Ga_{0.6}Fe_{0.4}O_{3-\delta}$, with over $40\%\;of\;CH_4$ conversion and syngas yield. $La_{0.7}Sr_{0.3}Ga_{0.6}Fe_{0.4}O_{3-\delta}$ membrane was stable even when it was exposed to the reducing environment, methane, for 600 hrs at $950^{\circ}C$.

실크로드와 그것이 한국문화에 미친 영향

이승영(Sing Young Lee) 한국경영사학회 2005 經營史學 Vol.36 No.-

The Silk Road is a general term of a passage way that connected China and many Western countries in view of politics, economy, and culture upon the ancient trade of silk, but more often it means the pathway thru Central Asia s oasis (so called, Oasis Route). At the early stage only the western-centered concepts were brought, but soon, it became the pathway of the cultual exchange between the East and the West including the religions such as the Buddihism, the Zoroastrinism, the Manichaeism, and the Islam. As the Silk Road, our culture was also formated by the continuous trades with those many neighboring countries. Therefore, this study discovers the meaning of the Silk Road and its transitions upon histories as the pathway of the cultural exchange between the East and the West. Ultimately, this syudy aims the Silk Road s influences over the cultures in ancient Korea. It is believed that Korea was influenced by the Northern Culture, the Scythian culture, before the Bronze Age, as many relic of the past tells us. O-bo or Seo-nang-dang s similarities also prove this. As many foreign cultures, the Buddihism was also brought into Korea thru the Silk Road in the old times. At least, we were influenced by the cultures from Turkey, which is known as the West in the East, Middle East and the Central Asia, to the far eastern Manchuria thru the Silk Road. Therefore, it is expected for us to discover the new Silk Road as the leading country in the East Asia at the 21st century s internet-era and construct our own Silk Road to globalize the Korean culture with the help of the late trend of world-wide Korea Boom. Furthermore, this will challenge not only explolers who have no fear on exploring the Third World but also the students of the trade department in Korea inspiring the spirits of challenge, patience, and bazar .

본 연구는 중국 운남성과 소수민족과 관련한 문헌연구에 연구자의 경험과 탐험을 더하여 선험자들의 기록과 대조 확인하고 체계적으로 정리하여 이문화 연구 및 중국 진출 및 이해에 관심 있는 비즈니스맨이나 경상학도들에게 중국과 변방 소수민족에 대한 이해를 높이고, 그들과의 비즈니스 접근시에 유의해야 할 지침 및 귀중한 정보를 공유하며 토론의 자료를 제공하는 데 목적을 두었다. 단일민족으로 우월감을 가지고 있는 우리로서는 21세기 지구촌 다문화시대를 성공적으로 주도하기 위해 운남성 소수민족사회에서 지혜를 얻을 수 있다. 또한 본 연구를 통해 몇 가지 비즈니스 및 마케팅상의 교훈을 찾을 수 있다. 무엇보다 각 지역별로 다양하고 차별화된 최고의 도시마케팅과 소수민족을 중심으로 한 문화상품은 우리에게 많은 교훈과 시사점을 제시한다. 무엇보다 중국 소수민족의 조화가 오랜 지역갈등과 분단의 비극을 겪고 있는 우리 민족에게 통합과 포용 그리고 세계화로 한 걸음 다가가기 위한 가능성을 현실적으로 보여주고 있는 것으로, 우리 모두에게 밝은 희망을 갖게 한다. The geographical ranges of minority races in China cover about 60 percent of the whole country. However, the majority of them dwell in the side areas of China where the population is sparse but rich in natural resources. Among these, Yunnansheng located in South-West of China bordering with Vietnam, Laos, and Myanmar has a third of 25 minority races out of the whole 55. These people rather have high economic status living harmoniously one another. The study aims to provide diverse information and discussion materials for business administration majoring students and businessmen who are interested in trade and business in China. For the purpose of the study this paper explored geographical features and customs of Yunnansheng in South-West China and investigated cultural aspects and the art of harmony among different races with their own different culture in races of Nixizu, Baizu, Yizu, Daizu and others in Dali, Lijiang, and Kunming. It is noteworthy that various and different cultures and customs of these different minority races are well preserved in their own way without serious troubles among them. The result of the study provides useful insights on cross cultural access and administration for Koreans who have to overcome the limit of being homogeneous people in the gloabal market of the 21st century.

The purpose of this study is to define the different stage of global management cultures for localization from the case study of two respective multinational corporations, Nestle and Samsung Electronics invested in Vietnam, and then to find out on how Korean multinational corporations can reduce the gap of global management culture compared to global multinational corporations. In fact, Samsung has been pretty much being on a right track from the global marketing management perspective, however still stand at the beginning stage in terms of leading the global corporate culture. In comparison to Nestle with over 130 years of worldwide business experience, Samsung Electronics having only a decade global experience as a Korean multinational corporation has been found to have an obvious gap in terms of globalization which is mainly caused by global corporate culture. Even though it doesn’t seem realistic for Korean multinational corporations to immediately catch up the gap of global corporate culture against global multinational corporations with long years of global experiences and history, Korean multinational corporations need to track the foot print of every steps of globalization particularly focused on the local management culture of global multinational corporations, so that they will be able to shorten the timing to develop the true meaning of global corporate culture being evolved from the Korean management style.

이승영(Sing-Young Lee),총여명(Li-Ming Cong) 동국대학교 경영연구원 2007 경영과 사례연구 Vol.30 No.2

중국이 1979년 공식적으로 개혁개방정책을 표명한 후 몇 차례에 걸친 대대적인 개방정책이 실제적으로 이루어졌다. 해외직접투자(FDI)는 중국정부가 외국투자를 유치하는 주요한 방식으로 중국경제발전에 큰 공헌을 한 것으로 평가된다. 이에 본 연구는 중국의 개방 이후 현재까지 FDI 유치 추이 및 현황, 그리고 외국인투자유치 정책에 대하여 해외투자이론에 근거하여 분석하고, 이를 바탕으로 중국의 FDI 발전 추세를 전망하고 정책조정 방향을 제시하는데 근본 목적을 두었다. 나아가 중국의 투자환경 및 중국진출 다국적기업의 경쟁상황을 파악하여 한국 투자기업의 대중국 진출상의 유의점을 모색하는데 궁극적 목적을 두었다. Since China started reform & Opening-up in 1979, the reform and opening-up policy has been well implemented after several phases of developments. As major means of attracting foreign investment of Chinese government, Foreign Direct Investment (FDI) has made great contributions to China s economic development. Therefore, the purpose of this Research is to introduce the status and development trend of FDI after China s opening-up, analyze the policy on attracting foreign investment based on overseas investment theory, foresee the development trend of FDI in China, and bring forward the policy adjustment. Nowadays, China s investment environment is getting more and more complete, the competition of multinational companies in China will be more severe, and Korean companies will be well advised while entering Chinese market.This Research covers as follows:1. FDI is the motivity of the economic development of China. After the reform & opening-up, China s economic development cannot avoid the integration with overseas capital, which is the necessary factor in the process of the developing of China s economy. 2. The dynamic developmental point of view should be used while analyzing the elements affecting FDI, and China s investment environment also needs to be analyzed with the developments and changes of neighboring countries and the world. 3. China s utilization of FDI is turning from labor-densified and low-tech projects to high-tech ones, therefore, the FDI issues in China shall be viewed from different angles. China is engaged with building a better investment environment to attract more high-tech projects. With the editing of FDI policies, China will learn more technology, which will become anew power for the growth of Chinese economy. 4. China should make corresponding adjustive policy according to the investing purposes and growing opportunities of multinational companies, so as to be in harmony with the great division system of the world, and speed up the process of China s international factory strategy.China is becoming the revitalization hope of the economy of Asia and the world, the market competition will be more severe with the entry of more competitive companies, which means development and also competitive market to Korean companies, so the Korean enterprises should learn to deal with it with self advantages. After entering China, FDI enterprises should use self advantages, combine with China s domestic conditions, search for the breakthrough to success, and try to create ultimate value.

장보고 정신과 무역대국의 재현

이승영(Sing Young Lee) 한국국제통상학회 2002 국제통상연구 Vol.7 No.1

Changpogo, having manifested a full grip on the North-eastern seas of the Far-east which meant the whole world then, initiated true trade man`s spirit by successfully leading trades among Shilla, Tang and Japan some 1,200 years ago. This paper aims to search ways to revive Changpogo spirit for the re-creation of great trade nationhood by way of studying his philosophy on trade and his vigorous activities in trade. Changpogo manifested a perfect attitude and qualification of international businessman such as adventurous spirit, courage, outstanding persuasive ability, leadership, insight into complete international relations and world trend His greatest achievement was the opening the era of private trade which was a free trade at that time. Furthermore his use of a network around Shilla-bang and the likes was a matrix of today`s multinational enterprises. Changpogo, having his headquarter on Chunghaejin in Wando island in Chollanamdo, in the latter part of Shilla dynasty wielded a tremendous hegemony over marine administration in northeastern sea which helped the Korean peninsula to be a center of international trade. Changpogo who actualized his maxim, He who controls the sea controls the whole world. is a great mentor even in the 21st century in Korea Changpogo is also a model for the internationalization and localization, the two essential matters in international trade and for the international CEOs as well. Faced with the 21st century globalization era, it is an imperative task in order to revive the spirit of Changpogo and dream of great trade nationhood, and to establish cooperative Changpogo models, organizations of new Shilla-bang through overseas Korean communities, and training of at least 100,000 tradesmen who could do justice to the name of true descendent of Changpogo.
