The main purpose of this study is to examines peculiar competitive advantages of Korean women businessmen(Han-Sang) in Australia. The results of case analysis are summarized as follows. First competitive advantage is CEO’s excellent dynamic capabilities like wonderful adaptability, woman’s unique delicate management style, mom’s unique emotional leadership and showing leadership by example. Second competitive advantage is Korean peculiar sincerity and diligence, can-do spirit, perseverance and fast implementation. Lastly, The social status as Korean immigrants made them weak position in Australian society but it was found that they have made weakness a strength. They built up the solidarity with Korean immigrant society and took advantage of it for their business. Based on the results, implications for researchers and practitioners are discussed. 본 연구는 해외에서 중소기업을 운영하고 있는 한상 여성 기업인이 어떤 한국적 경쟁우위를 바탕으로 사업을 성공적으로 수행 할 수 있었는지 탐색하기 위해 호주 여성 한상 중소기업을 대상으로 그 요인들을 규명하고자 하였다. 사례 대상 기업은 호주에 소재한 2개의 기업으로 시드니에 본사를 둔 청소용역업체인 “제마이홀딩스”와 호주 전역에 27개의 체인점을 둔 스시레스토랑 “스시베이”이다. 적용 이론으로 마이클포터의 다이아몬드 모델을 선택하여 두 기업에 대한 경쟁우위를 분석하였다. 분석결과, 경쟁우위 요소는 다음과 같다. 첫째, 가족기업으로서 여성 CEO의 탁월한 동적역량이다. 변화 환경에의 탁월한 적응능력, 여성으로서의 섬세한 경영, 엄마와 같은 감성적 리더십, 솔선수범 정신 등이 그것이다. 둘째, 한국특유의 문화에 기반한 성실과 근면, can-do 정신, 규율, 인내 그리고 빠른 실행력을 들 수 있다. 그리고 한인 기업인들의 이주자라는 사회적 지위는 그 사회에서 열세로 작용하지만 그러한 이주자의 특성을 살려 이주자사회와의 연대를 적극 활용하였다는 점도 발견할 수 있었다.

The purpose of this study was to examine the awareness of Korean-Japaneses on the reunification of the Korean peninsula. The findings of the study were as follows: First, more than half of the Korean-Japaneses investigated were interested in national reunification, and agreed with the reunification of the South and the North, the necessity of peaceful reunification and collaboration from the four neighboring powers, the contribution of reunification to the conflicts resolution of the Korean-Japanese society and its contribution to peace in East Asia. Nearly 50 percent agreed to participate in national reunification. In contrast, less than four out of the 10 respondents agreed with the contribution of reunification to the interests of individual Korean-Japaneses, the necessity of the fulfillment of the joint declaration of the two Koreas, one-sided reunification by one of the two and neutralized reunification. Second, mutual hostility and distrust between the two Koreas were cited as the causes to make it difficult to achieve reunification. Trust building was considered necessary to overcome the national division, and human rights were viewed as one of major values that should be considered important on the unified Korean peninsula. China was chosen as the country that was most opposed to reunification. Third, one out of the two believed that reunification was possible to achieve. Naturalized Japanese citizens were regarded as a group that had the least interest in reunification. The lack of interest from Korean-Japaneses was looked upon as the biggest difficulty that they faced in terms of reunification, and bolstering Korean-Japaneses" will to reunify was most stressed as a way to achieve reunification. Jochongryeon, which is the pro-Pyeongyang federation of Korean residents in Japan, was viewed as a group that was most active in reunification movements, and indifference that was attributed to the lack of promotion efforts was cited as the reason that made it hard to spread collective reunification campaigns. The first thing that is necessary for the revitalization of reunification movements is strengthening people"s will to reunify and making them come together. The second is creating the kind of environments that can accelerate reunification. The third is sustained promotion on the necessity of reunification and related education.

한국형발사체 개발 사업으로 고흥 나로우주센터에는 연소기, 터보펌프, 엔진의 성능시험을 위한 각각의 시험설비가 구축되어 운영하고 있다. 터보펌프 실매질 시험설비는 엔진 하부시스템인 터보펌프의 시험을 위해 산화제(LOX)와 연료(Jet-A1)를 매질로 시험하는 설비이다. 75톤 터보펌프 실매질 시험 결과를 통해 시험 전 이론식으로 예측한 유량과 제작된 오리피스의 크기에 대해 비교하였다. 그 결과 정확한 유량예측을 위한 오리피스 설계시 고려할 보정계수를 도출하였다. 또한, 유동해석을 통해 시험설비 연료시스템의 특성을 분석하였다. Test facilities have been constructed for the performance tests of combustion chambers, turbopumps and engines in the Naro Space Center under the development program of KSLV-II. The TPTF (Turbopump Real-Propellant Test Facility) has been developed for the real propellant tests of the main (75-ton thrust class) and the upper stage (7-ton thrust class) engine turbopumps using liquid oxygen as an oxidizer and kerosene(Jet-A1) as a fuel. The predicted flow rates through the TPTF kerosene line with designed orifice sizes have been compared with the 75-ton turbopump real-propellant test data. As a result, the correction factors for designing the orifice size have been obtained to predict the accurate flow rates. The CFD (Computational Fluid Dynamics) has been applied for the flow analysis of the test facility kerosene system.

Performance tests of a turbopump for the developing 7-tonf liquid rocket engine were conducted. The performance of turbopump components and their power matching were measured and examined firstly under the LN2 and water environment.. In the real propellant(LOX and kerosene) environment tests, design and off-design performances of turbopump were fully verified. During the off-design tests, turbopump running time was set the same as engine operating time and pump inlet pressure were set lower than nominal operating value in order to investigate pump suction capability. It have been verified that subject turbopump satisfies required performance - flow rate, head, suction performance and operational time - in the operating regime of developing liquid rocket engine.

75톤급 액체로켓엔진용 터보펌프 개발 시제에 대한 조립체 성능시험이 터보펌프 실매질 시험설비에서 수행되었다. LN2와 케로신을 적용한 첫 시험에서는 터보펌프 단품들의 조립체 레벨, 설계회전수 근방에서의 수력/공력 성능 및 출력 매칭 점검이 이루어 졌으며 LOX와 케로신을 적용한 실매질 시험에서는 터보펌프의 설계성능 및 엔진운용영역 탈설계 성능 검증시험이 이루어졌다. 탈설계시험의 경우, 엔진의 운용시간을 초과하여 터보펌프가 운용되었으며 펌프입구압력을 설계 요구유효흡입 양정(NPSHr)에 가깝게 설정하여 흡입성능 검증을 병행하였다. 개발된 75톤급 액체로켓용 터보펌프는 성능, 운용시간의 엔진 요구규격을 잘 만족시키는 것으로 확인되었다. Performance tests of the developing 75-tonf liquid rocket engine turbopump were conducted. The performance of sub-components - two pumps and a turbine - and their power matching were measured and examined firstly near the design speed under the LN2 and kerosene environment. In the real propellant - LOX and kerosene - environment tests, design and off-design performance of turbopump were fully verified in regime of the rocket engine operation. During the off-design performance tests, turbopump running time was set longer than the engine operating time and pump suction capability were investigated in parallel by setting the pump inlet pressure close to design NPSHr. It have been found that developed-turbopump satisfied all of the engine required performances.
