In the maritime industry, the convergence of information and communication technology (ICT) occurs in two areas. The first one is the convergence of e-navigation technology to apply ICT to the maritime domain. This was led by EU's initiative and is also being promoted in our country. The other one is the convergence of autonomous ship technology to apply various ICT technologies for commercial purposes. This initiative is being led by maritime industries. In this paper, we describe trends of e-navigation and maritime autonomous surface ship technology convergence. Subsequently, we explain the standardization status of performance and technical standard bodies, international standardization organizations, and related standard-developing organizations to provide the interoperability of these technologies. Finally, we examine ongoing projects in Korea and suggest future directions for their R&D and standardization.

The importance of information technology (IT) has been emphasized in developing countries recently. Despite the importance of the topic area of the productivity of IT in developing countries, the literature to date is relatively sparse. The findings of almost all these studies are based on data collected in developed countries. Few studies have been conducted to validate these results and to see if they are still applicable in developing countries. This study tries to investigate the effects of IT investment on productivity in the electronics industry of China, which is a representative developing country, with production function model. The results show that there is a positive impact of IT investment on productivity in China similar to previous studies in developed countries.

본 연구는 1990년대 우리나라를 포함한 OECD 국가의 지식기반산업 현황을 기술하고, 지식기반산업에서 IT 산업의 역할을 분석하는 데 목적이 있다. 1990년대 OECD 국가들의 지식기반산업의 중요한 특징은 OECD 각 국가들이 지식기반산업을 미래 중요한 산업으로 인식하고 지속적 자원투자와 관심을 기울이고 있다는 데 있다. 본 연구에서 대상 분석기간 동안 OECD 국가의 지식기반산업성장률은 5% 증가하였으며, 우리나라의 경우는 이보다 높은 10%대의 증가를 기록하였다. 또한 OECD 국가들의 지식기반산업 형성과정에서 IT 산업은 전통적 제조업의 역할보다 기술혁신 측면과 무역수지 측면에서 매우 중요한 역할을 수행한 것으로 나타났다. 특히 우리나라의 경우에 지식기반산업의 형성과정에서 IT 산업의 기여도는 다른 OECD 국가보다 높은 것으로 나타났다. 지식기반산업 가운데 IT 산업은 생산성 증가요인을 분해하여 볼 때, 전반적으로 산업간의 효율성에 의한 생산성증가, 산업간의 자원이동에 의한 생산성증가 그리고 IT 산업자체의 노동생산성증가 요인에서 다른 산업에 비하여 상대적으로 우월하게 나타났다.

본 논문에서는 음성정보기술산업지원센터(SiTEC)에서 현재 배포중인 고소음 환경 음성 DB를 이용하여 air-conducted 음성과 body-conducted 음성의 인식 성능을 비교 실험하였다. 소음 환경에서 일반적인 마이크로폰으로부터 수집된 air-conducted 음성은 잡음의 영향을 받기 쉬우며 이는 인식률을 저하시킨다. 반면에 진동 픽업 마이크로폰에서 수집된 body-conducted 음성은 소음에 보다 강인한 특성을 보인다. 이러한 특성에 근거하여 소음 환경에서 일반 다이나믹 마이크로폰 음성에 음질 개선 방법과 채널 보상 방법을 적용한 인식 결과와 3종류의 진동 픽업 마이크로폰에서 수집된 음성과의 인식 성능을 비교 분석하여 body-conducted 음성 인식 시스템의 환용 가능성을 살펴보았다.

The purpose of this article is to abstract Industries 4.0 Top documents and express the fundamental strategies. It is clear that disruptive AI + ICBM technology will change the entire industry, and therefore each country is making a strategy to prepare for the future. Example cases are Japan's Monozukuri, Germany's Industry 4.0, the USA's Reshoring, and China's Made in China 2025. I would like to introduce Industrial Industries 4.0 in Germany because Germany used the industrial industries' term first and Korea has as many SMEs as Germany has. The main characteristic is that it can be applied to the size of the individual SMEs rather than the national size.

Recently SMT is used widely to place the SMD on bare board which is very small and highly integrated. And that is one of the issue directly in the electric products assembly process and especiallly in the field of optimizing electric product's performance, automatically tuning method which is highly demanded in the electronics industry. To tune product's performance, variable resistances's resistivity should be changed until it has good performance characteristics. In this paper to automatically regulate the 8mm camcoder's performance, it is proposed variable resistence's center position and orientation detection algorithm by image processing, which has very precise and accurate result. And we found optimal conditions which can have effects on image acquisition process. And real time processing is done by DSP to detect vr's center and orientation. This results make it possible to utilize proposed image processing algorithm and system directly in electronics industry.
