  • 2000년대 이후 전 세계적으로 곡물 재고율 하락이 장기화되고, 인구증가 및 생활 여건의 개선에 따라 식량부족 상태의 심화가 예측됨에 따라 세계 각국은 곡물의 생산성 제고 및 품질향상 방안을 확보하고자 노력하고 있다. 농업 IT 융합기술은 기존의 농업기술에 IT 고유기술을 농업에 융합시켜 농업의 생산 유통 소비 전 과정에 걸쳐 생산성과 효율성 및 품질향상 등과 같은 고부가가치 창출을 추구하고자 하는 기술이다. 크게 보면 축산업 분야도 포함되는 것이지만 여기에서는 재배 작물의 생산에 국한하고, IT 기술 중에서 USN 기술을 적용한 USN 기반의 IT 기술을 농업에 융합하는 분야로 한정한 기술의 연구 동향을 고찰하고자 한다. 노지 작물과 시설원예 작물 및 외부 환경에 영향을 받지 않는 새로운 개념인 식물공장에 IT 기술을 적용하기 위하여 필요한 사항을 고찰하고, 국내외 기술개발 및 표준화 동향과 향후 추진되어야 할 기술적 이슈들을 제시하였다.

  • This paper measures R&D efficiency and productivity changes of 24 nations including Korea, Japan and China by the non-parametric Malmquist productivity index. The principle findings of this study are as follows. First, R&D efficiency scores of Korea and Japan are 0.837 and 0.834 respectively. Meanwhile China shows 0.420, the worst performance among the selected countries. Second, Korea marked annual productivity increase of 25%, highest among the selected countries', for 2000-2005. R&D productivity in Japan and China, however, decreased 1.9% and 0.9% respectively. Third, annual rates of technology change and technical efficiency change in Japan are 0.6% and -2.5%. Therefore decrease of productivity in Japan is mainly due to technical inefficiency. In case of China, improvement of technical efficiency is the main contributor to productivity growth but technical progress has edged downward in the sample period. In Korea, with annual rate of technology change and technical efficiency change being 5.2% and 18.2% respectively, both efficiency improvement and technical progress has pulled the R&D productivity growth.

  • A well-established characterization method is required in powder bed fusion (PBF) metal additive manufacturing, where metal powder is used. The characterization methods from the traditional powder metallurgy process are still being used. However, it is necessary to develop advanced methods of property evaluation with the advances in additive manufacturing technology. In this article, the characterization methods of powders for metal PBF are reviewed, and the recent research trends are introduced. Standardization status and specifications for metal powder for the PBF process which published by the ISO, ASTM, and MPIF are also covered. The establishment of powder characterization methods are expected to contribute to the metal powder industry and the advancement of additive manufacturing technology through the creation of related databases.

  • The objective of this study is to evaluate the effectiveness of new operation system for port container terminals. We assumed that the operation system of container terminal consists of monitorig & control system, operation system, planning system, and information technology, and we selected total 19 technology alternatives. Through the results of questionnaire and interview received from field expert, we established the evaluation model and analyze the productivity improvement by estimating the weight and the priority of productivity for operation system. From the developed model, we provide useful implications to introduce new technologies of operation system for domestic container terminals.

  • 중소기업의 기술혁신은 제품의 생산성을 높임으로써 궁극적으로는 새로운 영역에의 참여와 고용창출 효과를 가져올 뿐만 아니라 국가의 수출경쟁력에 이바지하는 기여도가 매우 높다. 중소기업은 규모가 작고 유기적인 조직구조의 특성상 탄력적으로 기술혁신에 대처할 수 있는 유리한 면이 있지만, 국내의 중소기업 기술혁신은 매우 열악한 상태이다. 따라서 대기업을 위주로 형성되어 있는 통합생산관리시스템(CIM)의 개념을 도입하고 산업용네트워크와 통합생산관리시스템을 적용하는 중소기업 기술혁신의 추진전략에 대해 설명하였다.

  • Technological innovations is a main source of competitive advantage and at the same time, it needs great investment to achieve it. So in the back of many successful firms, always there is great technological innovation and much investment to achieve it. But investment in technological innovation does not always give good performance. In this paper according to the technological innovation model presented by Abernathy and Utterback(1975), the relationship between technological innovation and manufacturing strategy/ manufcaturing activity is testified by domestic firms empirically. The ultimate purpose of this paper is to prepare for basement of normative research on technological innovation to improve firm performance.
