        This paper proposes that the proper exegesis of the Three Angels’ Messages can be established only by careful analysis of Revelation 12 and 13 as the backdrop for the Messages. There are two sets of competing messages: The urges of the earth beast, and the countering warnings of the three angels. And the inhabitants of the world were threatened by the angels just as the saints were threatened by the coercion of the earth beast backed up by the sea beast and the dragon.

      • 植物 生長調整劑의 處理가 水稻幼苗의 蛋白質 含量 및 酵素 活性에 미치는 影響

        디지털화를 통한 케이블TV 융합전략과 공정경쟁 규제이슈

        김도연 정보통신정책학회 2004 정보통신정책연구 Vol.11 No.3

        케이블TV는 사용하는 네트워크와 제공되는 서비스, 그리고 사업자들의 행위 등에서 통신ㆍ방송 융합의 가장 선도적인 산업부문으로 인정되어왔다. 케이블TV 산업은 주요국에서 산업으로 성장하며 일정 규모의 초기가입자와 네트워크 외부성, 그리고 규모와 범위의 경제를 구현하는 산업적 특성을 형성하며 이러한 성격들을 융합산업으로의 변모에 활용하려고 하는 반면에, 국내의 경우 케이블TV 도입 초기의 시행착오를 거쳐 이행기의 어려움을 돌파해 줄 해결책으로 디지털화를 총한 융합 전략을 채택한 면이 크다. 국내 케이블TV 산업계에서는 구체적으로 디지털미디어센터(DMC)의 구축을 통해 트리플 플레이 서비스(TPS)의 제공을 추구하는 것을 융합 전략으로 하고 있다고 하겠다. 그러나 이의 추진과 성공을 위해서는 결합상품에서의 상호보조의 문제와 수평적, 수직적 기업견합에서의 시장지배력에 대한 합리적인 규제기준을 마련하여 새로운 융합 상황에서의 공정경쟁 환경을 조성하는 것이 중요하다고 할 것이다. Cable TV has been recognized as an industry which is the most advanced for convergence in its network, service, and players' conduct. In advanced countries, cable TV grew to be a typical industry, reaching to the critical mass in its early stage, getting network externality, and utilizing the economies of scale and scope, which have led to the transformation into convergence industry. In Korea, however, cable TV has struggled with lot of trials and errors from the beginning, and adopted the strategy of digitalization to overcome them. More concretely, Korean cable TV industry has established the convergence strategies to built digital media centers(DMC) and to provide triple play service(TPS). However, to propel and succeed in the convergence strategies, a proper regulatory scheme is required. Especially, the regulation of cross subsidization in bundling products and the control of market governance execution are important in order to establish fair competition environment in convergence market.

        가공 열처리에 따른 Ti-10Ta-10Nb합금의 미세조직 및 기계적 특성 변화

        이도재,황주영,이경구,윤계림,전충극 한국열처리공학회 2005 熱處理工學會誌 Vol.18 No.2

        Both commercially pure titanium and Ti-6AI-4V alloy have been widely used as biomaterials because of their excellent biocompatibility, corrosion resistance and mechanical properties. However, in recent years, vanadium has been found to cause cytotoxic effects and adverse tissue reactions, while aluminium has been associated with potential neurological disorders. A newly designed α+ß type Ti alloy, Ti-10Ta-10Nb alloy showed superior properties to CP Ti and Ti-6AI-4V alloy in the point of biomaterial, and elucidated the future uses as a biomaterial. Microstructural changes of Ti-10Ta-10Nb alloy after hot-rolling, warm-rolling, solution and aging treatment were investigated. According to TEM results, the microstructures after solution treatment were composed of mostly α phase with a trace of ß phase due to adding ß-phase stabilizer tantalum and niobium. The microstructures after warm-rolling is coarse and elongated a phase and hot rolling resulted in very fine a widmansta¨tten. The highest value of hardness was obtained by aging treatment at 400℃ for 20hr in which microstructure consisted of very fine a phase in β matrix.
