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 $950^{\circ}C$.

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.

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 .

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.

한·미·일제품의 소비자 인지에 (認知) 대한 비교연구 - 원산지국과 상표국의 이미지를 중심으로 -

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.
