The broadcasting communications service will accelerate its development with the convergence of broadcasting media and internet service. In the field of CATV network related technology, only those service providers will be able to survive in future, and they can combine available services in the most effective and economical way. This research aims to explain the CATV status of Korea and China and its technology trends. It also analyzes CMC(Cable Modem Concentrator) technology, suggested as one of the high-speed internet technology. CMC technology has the advantages of enhancing the transmission speed while using the existing basic structure of HFC network and expanding service area by adding amplifiers within CMC. The distance between coaxial cables is getting shorter with more concentrated areas in large cities in Korea. However, in China, the demand for long distance transmission service is increasing. CMC technology satisfies both short and long distance service subscribers without any geographical limitations. With these advantages, CMC technology is expected to generate lots of economic benefits if applied for the CATV network in the area of China, Middle East, and Southeast Asia.

It is only 9 to 10 years since the use of internet became commercial. But electronic commerce is now a familiar form of commercial transaction. Though the ratio of electronic commerce compared to total commercial transaction is still low, it is certain that electronic commerce will be the major form of transactions in the future. In July 1, 1997, United States made a public "A Framework for Global Electronic Commerce" to set up Internet to be a duty free zone and declared to play the trigger role in getting the international discussion of "A Framework for Global Electronic Commerce". In July 8, 1997, EU also adopted "Bonn Declaration"-minimizing government regulations and imposing no new tax on electronic commerce. Focusing the international trend, we need to develop the tax policy that is suitable for our country situation as soon as we can. To be able to do that, we must make an endless effort like selecting professionals, making new administrative part and supporting the research.

The current space activities are soaring ever since the first human flight to outer space 50 years ago and the first satellite launch 54 years ago. 74 space launch vehicles were launched in 2010, up from average 66 yearly in 2000s, and 900 operational satellites are currently in orbit around Earth. Space has become a worthwhile investment for governments as space assets become vital to national social, economic, and technological development as well as contributing their national defense and security program. The world governments' investments on space programs have reached a historical peak of $71.5 billion in 2010. However, the growth of government funding for space has slowed down posting only a 2% growth rate since 2009 while 9 % compound annual growth rate experienced by world's space expenditures between 2004 and 2009. Korea invested $158 million in 2011, experienced strong decrease with a 16% compound annual growth rate since 2008. In this paper the current statuses of world governments' funding for space program and space market were presented and the current issues on the Korean space budget policy were reviewed.

UCI (Universal Content Identifier) as a national digital content identification system for identifying digital content and ICN (Integrated Copyright Number) for copyright management are operated by Korea copyright commission. However, They are not interoperable with international standard identification system such as ISRC (International Standard Recording Code), ISWC (International Standard Works Code), and ISAN (International Standard Audiovisual Number) due to lack of linkage system. Hence, extra works with international standard identification system are needed for international market entry and integrated management of statistical information including content settlement in international market is impossible. In this paper, the domestic/international identification systems are surveyed, and by metadata analysis of identification systems, linkage method with UCI/ICN is proposed. And also by developing the prototype model, research direction to UCI/ICN with international standard identification system is proposed.

국내광업은 ‘90년대 이후 석탄산업합리화조치와 국제금속광물시장 가격안정화로 그 동안 광업을 주도한 석탄산업과 금속광업은 급격히 위축되는 한편, 산업원료의 수요증가 추세에 힘입어 비금속광물 개발은 비교적 활발한 상태이다. 이와 같이 국내 광업의 주긴 영역이 석탄광과 금속광에서 비금속광 중심으로 개편되고 있으나, 현재 가행중인 비금속광은 고품위광체 확보 미흡, 고부가가치 기술낙후 등으로 고가의 주요 산업원료는 주로 수입에 의존하고 있는 실정이다. 따라서 국내광업으로서는 비금속광 중심의 단순한 원광식 생산$\cdot$판매체계를 고부가 산업으로 전환시키기 위한 전략적인 방안이 필요한 시기이다. 본 발표문은 이러한 국내광업의 향후 발전방향을 모색하기 위하여 국내 광업이 국가 경제에서 차지하는 영역을 중심으로 $\boxDr$광업동향$\boxUl$ $\boxDr$광업의 국내$\cdot$외 환경분석$\boxUl$ $\boxDr$광업의 경제활동 현황$\boxUl$ $\boxDr$광업의 경제적 위치와 역할$\boxUl$로 분류하여 자료분석을 실시하였으며, 분석한 자료를 토대로 국내광업의 중요성과 당면과제를 도출하고 이에 따른 광업의 새로운 역할을 제시하고자 하였다. 국내광업은 각종 지표에서 나타난 바와 같이 여러 가지 구조적인 문제점으로 인해 개발에 어려움을 겪고 있지만 각종 산업원료의 중간재 공급원으로서의 전통적인 역할을 충실히 담당하고 있는 것으로 분석되었다. 그러나 과학기술의 급격한 발달, 소비패턴의 변화, 생활환경과 삶의 질을 중시하는 새로운 가치관의 확산 등으로 광업의 역할도 새로운 변화의 전기를 맞이하고 있음을 볼 수 있다. 국내광업이 21C 급변하는 산업환경에 적응하여 생존하기 위해서는 각종 첨단산업에서 요구하는 소량 다품종의 원료광물을 적기에 공급 할 수 있는 전문화된 기술력을 하루속히 확보해야 하며, 이를 위해 고품위의 원료광물 확보를 위한 탐사 및 개발을 적극 추진하고 가공기술의 선진화를 위해 선진국과의 기술제휴 등 자원산업 글로벌화 정책이 절실히 요구되고 있음을 알 수 있다 또한 삶의 질을 향상시키려는 현대인의 가치관에 부합하기 위해서는 각종 소비제품의 원료를 제공하는 광업의 본래 목적 이외에도 자연환경 훼손을 최소화하며 개발 할 수 밖에 없는 구조적인 어려움에 직면할 수 밖에 없다. 이처럼 국내광업이 안고 있는 여러 가지 난제들을 극복하기 위해서는 업계와 정부가 합심하여 국내광업 육성의 중요성을 재인식하고 새로운 마음가짐으로 관련 정책을 수립 일관성있게 추진해 나가야 할 것으로 보인다.
