In this paper, we investigate the economic repercussion effects of the domestic satellite industry. The market size of the satellite industry between 2005 and 2009 is forecasted based on the world market forecast. By using the Input-Output analysis technique, three kinds of repercussion effects (domestic production, value added, workers induced by the satellite industry) between 2005 and 2009 are calculated.

Vietnam is the country with the largest animal feed production in Southeast Asia. Domestic animal feed manufacturing enterprises play an important role in animal husbandry in particular and in agriculture in general. However, domestic animal feed enterprises in Vietnam are encountering shortcomings. This paper is conducted to investigate the impact levels of external determinants on business performance of domestic animal feed manufacturing enterprises, including: (i) policy and economic mechanism, (ii) supply-demand of animal feed products, and (iii) nature and level of market competition. We presented a research method, explaining the dependent variable 'business performance' and the independent variables. Data were collected from 120 questionnaires from domestic animal feed manufacturing enterprises. Based on these data, we use Cronbach's Alpha, EFA and run regression model for assessing the impact levels of each independent variable on the dependent variable of business performance of domestic animal feed manufacturing enterprises. The results show that three external determinants including (i) policy and economic mechanism, (ii) supply-demand of animal feed products, and (iii) nature and level of market competition, have positive relationships with business performance. Based on the findings, some recommendations are given for improving business performance of domestic animal feed manufacturing enterprises to ensure sustainability.

Ultra-precision machining technology is the essential core technology in today's micro-electronics and electro-optical industries. The needs for processing systems to manufacture products to nanometer(nm) accuracy and sub-nanometer resolutions are increased recently. By using ion beam, it is possible to fabricate ultra-precision and ultra-fine products with nm accuracy and sub-nm resolution. In this paper, the basic research trends of ultra precision machining technology in domestic are surveyed, and the ways to reach to the world-leading level of basic research capabilities in the field of ultra-precision machining technology in domestic is suggested.

In order to facilitate the introduction of BIM technology in the construction project of fact, many countries such as Singapore and the United States, is developing a roadmap of BIM technology development. To develop this, recently, it must be analyzed in advance the state of BIM technology domestic projects. In this study, we define the elements of technology BIM, and analyzed the current situation. In addition, I was evaluated and priority importance to the elemental technology derived. As a result, elemental technology most was the level inferior to foreign countries, and the field of ordering standard planning and has been highly valued and priority of particular importance, but currently, the level of domestic, analysis and most delayed has been. These results are judged to be useful in the development of the roadmap and direction of technological development of BIM in the future.

In this research, policies, and technology trends associated with quantum computers were examined, and through this, implications for domestic methods were derived. It is not a guarantee that developing quantum computing technology suited for domestic use would be successful to emulate the success stories of technology-leading nations. Technology leaders like the United States, China, and Europe are putting together strategic technology blocks to compete for technological hegemony. Adapting to and exploiting this trend will help us develop future technologies and secure market competitiveness. The dominant technology in the area of quantum computing has not yet been established. In the future, there will be fair competition in every specific technology area. At this point, it may be claimed that making audacious decisions will still lead to technological superiority.

Purpose: The purpose of this study is to derive major policies that domestic small and medium-sized manufacturing companies should consider to maximize productivity and quality improvement by utilizing manufacturing data and AI, and to find priorities and implications. Methods: In this study, domestic and international issues and literature review by country were conducted to derive major considerations such as manufacturing AI technology, manufacturing AI talent, manufacturing AI data and manufacturing AI ecosystem. Additionally, the questionnaire survey targeting 46 experts of manufacturing data and AI industry were conducted. Finally, the major considerations and detailed factors importance were derived by applying the Analytic Hierarchy Process (AHP). Results: As a result of the study, it was found that 'manufacturing AI technology', 'manufacturing AI talent', 'manufacturing AI data', and 'manufacturing AI ecosystem' exist as key considerations for domestic manufacturing AI. After empirical analysis, the importance of the four key considerations was found to be 'manufacturing AI ecosystem (0.272)', 'manufacturing AI data (0.265)', 'manufacturing AI technology (0.233)', and 'manufacturing AI talent (0.230)'. The importance of the derived four viewpoints is maintained at a similar level. In addition, looking at the detailed variables with the highest importance for each of the four perspectives, 'Best Practice', 'manufacturing data quality management regime, 'manufacturing data collection infrastructure', and 'manufacturing AI manpower level of solution providers' were found. Conclusion: For the sustainable growth of the domestic manufacturing AI ecosystem, it should be possible to develop and promote manufacturing AI policies in a balanced way by considering all four derived viewpoints. This paper is expected to be used as an effective guideline when developing policies for upgrading manufacturing through domestic manufacturing data and AI in the future.

국내 및 국외 뒤영벌 생산업체의 서양뒤영벌(Bombus terrestris) 산란율, 봉군형성률, 신여왕출현 봉군율 등 봉세발달 및 인공월동 후 생존율을 비교 조사하였다. 국내 3개와 국외 1개 생산업체의 창설여왕벌 봉군에서 생산된 일벌수는 232.4-270.8마리, 여왕벌수는 62.0-181.8마리로 다소의 차이는 있었으나 국내 및 국외 뒤영벌 생산업체간에 유의성은 없었다. 업체별로 생산된 여왕벌을 탄산가스처리후 사육한 결과, 산란율, 봉군형성률, 신여왕출현봉군율 등 봉세발달은 국내업체에서 생산한 서양뒤영벌이 유럽산보다 우수한 것으로 나타났으나, 일벌 및 여왕벌수는 유럽산 뒤영벌이 다소 많은 것으로 나타났다. 또한 국내 3개 뒤영벌 생산업체와 유럽 2개 업체에서 생산된 서양뒤영벌을 인공월동하여 사육한 경우에도 다소의 차이가 있었지만, 생존율 및 봉세발달에서 뚜렷한 차이가 없었다. 이와 같이 업체별로 생산된 창설여왕벌과 2세대 여왕벌의 휴면처리를 달리하여 사육한 결과, 국내 및 국외 뒤영벌 생산업체의 서양뒤영벌의 봉세 간에 차이가 없는 것으로 나타났다.

온실가스 배출을 감축하기 위한 각국의 노력이 활발해 지고 있으며, 그에 따라 석탄발전의 비중을 점차 줄이고 재생에너지 및 천연가스 발전의 비중을 높이려는 노력이 가시화되고 있다. 한국도 유사한 정책을 추구하고 있는데, 현재 LNG 발전 가치사슬 전체에 걸쳐 국산이 차지하는 부분은 매우 미미한 실정이어서 이러한 LNG 발전확대 정책이 국내 산업육성과 괴리는 있지 않은지 우려가 되는 상황이다. 따라서 본 논고에서는 LNG 발전에 사용되고 있는 가스터빈과 고온부품 산업의 국내외 현황을 살펴보고, 국내 가스터빈 산업의 Supply Chain 분석을 통해 국내 산업이 안고 있는 이슈와 문제점을 조사해 보았으며, 이를 기반으로 국내 가스터빈과 고온부품 산업의 활성화 및 국산화를 위한 전략을 제안하였다. 국내 가스터빈 산업육성 전략은 1) 가스터빈 얼라이언스 구성 등을 통한 국내 제조산업 생태계 조성, 2) 가스터빈 및 고온부품 국산화를 위한 전략적 기술개발 지원, 그리고 3) 국내 실증 테스트베드 구축 등 기술 사업화 촉진을 위한 환경 조성으로 요약될 수 있다.

The domestic label fuel economy measurement method is the same as the North American measurement method. The results of two test modes (city [FTP-75 mode], highway [HWFET mode]) are calculated to be equivalent to the final fuel economy value calculated as the result of five test modes reflecting various environmental conditions and driving patterns 5-cycle correction formula is used. In this study, we tried to find out that the difference between the domestic label fuel economy of the vehicle and the real road fuel economy felt by the driver compared to the new vehicle condition as the mileage increases. Using domestic label fuel economy measurement method, Four gasoline vehicles and four diesel vehicles were tested for the fuel economy of a new vehicle with a mileage of 150 km or less and domestic fuel economy test $6,500{\pm}1,000km$ durability condition and 15,000 km durability. It is confirmed that the certain portion (6,500 km endurance vehicle) The increase in mileage did not affect the fuel economy or the emission gas significantly, indicating that vehicle durability was limited.
