      • 정보기술협정에 따른 파급효과 분석 : 산업별 실효관세율 접근방식을 중심으로 Effective Tariff Rate Approach

        장근호 홍익대학교 산업기술연구소 2000 産業技術 Vol.10 No.-

        WTO 정보기술협정(ITA)으로 인하여 386개 품목의 정보,전자 관련 품목의 관세 등이 2004년까지 무세화된다. ITA 품목의 교역액은 1998년 당시우리나라 수입액 중 18.9%에 달하는 비중으로 금액으로는 무려 24.7조원에 이르며 수출액은 37조원에 달하는 중요한 산업이다. 특히 ITA 산업은 무역흑자 산업이지만 대규모로 흑자를 내는 산업은 소수 품목에 한정되어 있는 반면 무역 적자는 상당수 품목에 소액으로 분산되어 있다. 연구결과에 따르면 특히 ITA로 인하여 피해를 입을 품목은 전기 및 전자산업이며 혜택을 입을 품목은 소비재 관련 산업이 될 것이다. 따라서 이 부문에 있어서 중간재 산업의 관세율을 조정하고 이외 다른 정책적 지원이 대부분의 ITA 효과가 발휘되는 2001년까지 고려되어야 한다. 이 경우 물론 균등관세율 기조가 흔들릴 수 있지만 부분적 세율조정이 불가피하다. 물론 ITA 사업이 고도의 기술이나 상당한 설비투자를 필요로 하는 산업으로 우리나라가 전 분야에서 비교우위를 갖기는 어렵다. 하지만 정보산업기술이 그 특성상 다품종, 소액생산으로 높은 부가가치를 창출하는 산업이며 일부 국내산업의 경우 성장잠재력이 뛰어나다는 점을 감안하면 산업정책이 이 부문에 집중될 수 있어야 한다. ITA에 따른 부정적 효과를 최소화하고 연후 관세정책을 포함한 여러 가지 종합적인 정책으로 이 부문을 육성할 수 있어야 한다. Because of the WTO ITA(Information Technology Agreement), 386 information and electronic products will be assessed 0%'tariff rate by the year of 2004. The 1998 trade share of Korea's ITA products was 18.9% and the size in won amounted to 24.7 trillion won for import and 27 trillion won for export. However, trade surplus products are concentrated in a few industries while trade deficit products are large in number with deficits were spread among various industries. According to this study, electric and electronic part industry will suffer from the ITA but consumer product industry will benefit from it. Therefore it is necessary to adjust tariff rates on these products and other policies need to be implemented to complement the ITA by the year of 2001 when the most of the effect of the ITA begin to be felt. In this case, the principle of equal tariff rate will be harmed but it seems inevitable for the sake of industrial policy. Of course, ITA industry is characterized by advanced technology and/or a large size of upstart investment and in this sense Korea cannot have a comparative advantage in all of the ITA products. However, ITA industry tends to be, by nature, high value added products some domestics seems to have a competitive edge over foreign firms. Thus, the Korea government needs to provide a comprehensive policy to minimize the negative effect of the ITA and to develope the competitiveness of the domestic ITA industry, not to mention the overhaul of tariff policy in this area.

        Jonsson's study is briefly reviewed. Korean shipbuilding has followed the similar procedure which many early large scale shipbuilding countries had been through, but it has its own special characteristics associated with her historical legacy. Korea has become the world's first shipbuilder in terms of received order and this strikingly dramatic development is contributed to several important aspects. Japanese occupation between 1910-1945 provided Korean, to some extent, with basic shipbuilding skills and educated engineers, some of them played a crucial parts in educating naval architects later on. The high regard for education is an important asset for Korea and the abundance of such high educated naval architects made the quick absorption of the advanced foreign technologies possible. The government shipbuilding promotion policies also played key roles in enhancing shipbuilding in Korea. The amount of domestic delivery of ship has been rather underestimated but, as seen in the case of Sweden, the balance between export and domestic demand is very important.

      • 모바일 플랫폼의 표준화에 관한 연구

        曺成鉉 弘益大學校 産業技術硏究所 2004 産業技術 Vol.14 No.-

        Due to the hardware limitation of mobile platforms, 3D games could not have been running on mobile platforms until recently. However, the advance in the hardware technology of mobile platforms makes it possible to run 3D games on them. Mobile devices have been equipped with different hardwares and software environment. Without the standardization of mobile platforms, however, game developers, device manufacturers, and game users all have difficulties in developing games, making devices, and enjoying games respectively. Therefore, standardization forums have been formed to make mobile platform standards. In this paper, we first present the current situation of platforms and 3D game engines for mobile devices. Then we present mobile platform standards and 3D API technologies, and especially we focus on WIPI, which have been developed in and proposed by Korea.

      • 정체적인 시간적 Jitter 존재하는 기저 전송계에서 전력그펙트럼 밀도에 관한 연구

        池仁鎬,申鍾洪 홍익대학교 산업기술연구소 2000 産業技術 Vol.10 No.-

        The spectral occupancy and composition of a chosen digital signaling techniques when the data pulse stream is nonideal, due, for instance, to implementation imperfections, are important considerations in the design of a practical communication system. The purpose of this paper is to characterize the power spectral density(PSD) of baseband signaling schemes in the presence of arbitrary timing jitter. Although general PSD results are first obtained for arbitrary timing jitter statistics, specific results are then given for the cases of practical interest, namely, uniform and Gaussian distributed jitter. Examples of an uncorrelated data pulse stream, an independent identically distributed data stream, and a Markov source are given. Interesting results emerge when the generating sequence {a_n} is uncorrelated. For generating sequence {a_n} that are nonzero-mean, timing jitter has the effect of widening the main lobe of the spectrum and increasing the sidelobes. When the generating sequence is zero-mean and uncorrelated, rather surprising result is that the timing jitter does not affect the PSD. Simulation results are presented to verify the analysis.

        In this study, we reviewed the classification of the super-high-speed ship whose speed is larger than 50 knots and analyzed its mechanical engineering technology characterstics. It is concluded through this study that the traditional(mono or twin) hull form ship which is operated by buoyant force, lift force or air pressure has the limit in speed and size respectively to become to become the super-high-speed passenger and container ship. On the other hand, this analysis shows that the hybird hull form ship can be the super-high-speed ship. In this type of super-high-speed ship, there are SWASH ship, HYSWAS, LAHHS, HYACS, and SWAACS etc..

        Recent theories of economic growth have stressed the role of knowledge spillovers in generating grown. Such knowledge spillovers are particularly effective in local areas, where communication between people is more extensive. Some evidences suggest that important knowledge spillovers might occur between rather than within industries. Specialization hurts, and city diversity helps regional economic development. Therefore, local government should consider the role of knowledge spillovers in making strategies for regional economic development. Also, this paper stresses the role of central government in providing local public goods. If local public goods, such as school and safely, are major inputs of human capital formation thosse are the main factors that generate the future knowledge spillovers and nation's economic growth, which justifies the role of central government in helping local government.

      • 정보시스템 개발 기성관리에 대한 연구

        申東翊 홍익대학교 산업기술연구소 2000 産業技術 Vol.10 No.-

        본 논문은 최근 급격히 증가되고 있는 정보시스템 개발 사업에서 위험을 조기에 탐지하여 이를 적절히 대처함으로써 프로젝트의 위험을 줄이는 관리통제 방법으로 기성관리시스템을 제안하고 있다. 기성관리시스템은 이미 선진국에서 널리 보급되어 사용되고 있으나 우리나라의 경우 인식이 매우 부족하고 실무적으로는 사용이 전무하다 할 수 있다. 본 논문은 최근 연구되고 실무적으로 사용되고 있는 기성관리시스템의 개념과 체계를 소개하고, 기성관리시스템을 적용할 때 어려운 문제 중 하나인 기술성과 측정 방법을 제시하고 있다. 기성관리시스템은 비용, 일정, 기술성과를 통합적으로 관리하는 통제시스템이나 이 중에서 기술성과의 측정이 가장 어려운 부분이었으며 이로 인하여 기성관리에 어려움이 있어왔다. 본 논문은 좀더 현실적으로 적용 가능한 기술성과 측정방법을 구체적으로 제시함으로써 향후 우리나라에 기성관리시스템 도입을 촉진하는데 도움이 되고자 한다.

      • 고정식과 부유식 방파제의 특성 분석 및 적합성 연구

        For the optimum design of the wave control structures, design factors such as stability, economy, scenery, eco-control are to be considered and a priority should be given among these factors. At the beginning stability and economy were put as the first valuable factors, however as environmental problems are issued, scenery and eco-control factors are considered important. Design process and needed studies for the breakwaters are carried out in this paper based on the several related factors. Through the study it is recommended that the proper type of the fixed type breakwater is thought to be better one than the floating one, especially for the large offshore structure protection.

      • 기계적 합금화한 Al-50Ni 합금의 조직에 관한 연구

        金完哲,金容圭 홍익대학교 산업기술연구소 1993 産業技術 Vol.2 No.-

        Particle properties such as size, distribution, shape, composition, and structure are greatly influencing on the mechanical properties of final P/M products. Therefore, it is necessary that powders should be uniformed and strengthened by mechanical alloying. Degree of mechanical alloying of Al-50Ni powders can be determined by observing the microstructural refinement, microhardness, and microstructure of composite metal powder during processing. The mechanical alloying Process could be divided in five stages : initial stage, welding predominance stage, spherical particle formation stage, random welding predominance stage and steady state. Mechanical alloying reached to a steady state after 600 min processing as the finer lamellar microstruture could to no longer resolved in the 10∼20㎛ and the powder particle size distribution remained constant with processing time and a saturation hardness of 450 Hv had been attained. The rate of structural refinement of Al-50 Ni Composite was roughly logarithmic with processing time : ε= 2.915 ln(1 + 0.014t).
