IC는 수많은 전자부품중에서 가장 기본적인 부품으로서 현재 산업사회에서는 필수 불가결한 존재로 부각되어 있다. IC의 집적도는 SSI로부터 MSI, LSI를 거쳐 현재에는 VLSI의 단계가 실용화 되고 있으며 IC가 새로운 기기의 기능을 주도하고, 전기전자 공업의 발전에 원동력이 되고 있다는 것은 이미 기정 사실로 되고 있다. 최근 IC는 "산업의 핵" 또는 "산업의 공기"라고 불리울 만큼 그 역할 또한 큰 비중을 차지하면서 전 산업분야에서 폭넓게 사용되고 있으며 IC는 그 자체가 고도성장산업분야에 속해 있지만 IC가 산업의 미래상과 같이 중요성을 가졌기 때문에 최근에는 우리나라의 럭키금성, 현대, 삼성 및 대우그룹을 비롯하여 세계규모의 기업간 경쟁이 강화되어 가고 있다. IC시장은 1980년대의 전반기를 통하여 IC기술이 급속한 진보에 의해 다이나믹한 전개를 이룩한 것으로 볼수 있지만, IC시장의 장래를 전망하는 경우 세계적인 시점으로 보는 것은 매우 중요한 것이라 생각된다. 따라서 본 해설에 있어서는 서방자유세계를 중심으로 IC의 수급, 제품종별의 시장및 지역별 시장등에 관하여 1985년까지의 동향을 살펴보고 1980년대 전반기의 IC시장에 관한 흐름을 고찰하여 1980년대 후반기의 시장 및 기술개발의 전망에 관하여 기술하고자 한다.발의 전망에 관하여 기술하고자 한다.

IC industry is one of the foundation and core industries of modern information industry. Therefore, the study of this industry has important theoretical and practical significance. The main purpose of this study is to measure the degree of close correlation between the two indexes through correlation analysis of the selected indicators, so as to study the development trend and direction of IC. Based on the theory of induced innovation and the theory of comparative advantage, this paper analyzes the correlation between the profit of the IC industry and the following three indicators by using chart analysis method, covariance analysis method and correlation coefficient analysis method. These three indicators are R&D expenditure, new product development costs and annual export amount of IC. The selected data are mainly from CHINA STATISTICS YEARBOOK ON HIGH-TECHNOLOGY INDUSTRY. Through the research, it is found that the profit of China's IC industry is positively correlated with the first two indicators and negatively correlated with the annual export amount.

전문가들과 업계관계자들이 참여하게 된것은 IC카드산업이 미래정보화사회에서 차지할 비중이 상당히 클것으로 예상되며 IC산업볼륨자체가 인터넷과 기업 및 각 개개인의 컴퓨팅환경의 네트워크화에 힘입어 상당히 커질 것으로 전망되기 때문으로 풀이된다.

The purpose of this paper is to investigate various factors affecting the efficiency of China IC industry, reflecting the resource utilization and overall development level of China IC industry. In this paper, three input indicators (R&D Expenditure, Cash paid to and for employees, Total fixed assets) and two output indicators (Net profit, Sales revenue) were selected for 17 listed companies in the IC industry with operating profit of less than 1 billion yuan in 2018 and applied the technology efficiency theory and DEA analysis method to analyze the relative efficiency of the output base. The study found that one of the 17 companies analyzed was efficient, two were inefficient on an inadequate scale, and the rest were inefficient due to insufficient production technology, scale and management level. This study argues that enterprises should reduce resource input appropriately and strengthen scientific and technological innovation management to maximize resource utilization efficiency. Therefore, this study has important practical significance for improving the efficiency of IC enterprises. The Malmquist method will be used to study the total factor productivity of small and Medium-sized companies in IC industry.

In this paper, four types of igniters were modeled and their characteristics were researched. And then we analyzed and experimented the effect on the control IC operation in this system. Due to the high ignition voltage, the DC power line on control IC is contaminated with the impulsive noise voltage. So the control IC operation is stopped. Therefore we have found that contamination of DC power noise is reduced by shielding, grounding pattern, and filtering method. We showed that the experimental results are agreed with the theoritical value obtained by the four types of ignitor models.

This study presents the intellectual capital (IC) indicator selection criteria based on the review of qualitative characteristics of financial accounting information and data quality of information systems. The AHP survey has been performed to verify the weight difference of the criteria to select effective IC indicators among industry. The results shows that there exists the weight differences in relevance and comparability factor by industry. To management IC effectively, different method considering industry environment should be required.
