항공우주산업은 생산유발효과가 높고 고용창출도 높을 뿐만 아니라 부가가치산업이나, 대규모적 투자에 따른 투자 위험과 기술적 위험이 높아 정부차원에서의 개입이 불가피한 산업으로 인식된다. 최근 항공우주산업에 대한 정부의 지원 형태는 클러스터 조성, 지방세 감면, 토지 임대를 통한 기업지원 등 과거에 비해 더욱 다양한 형태로 발전되고 있다. 이와 같은 정부지원 형태의 다양성은 기존의 전통적 방식에 의한 지원으로는 글로벌 경쟁이 치열해지는 국제경쟁에서 경쟁력 우위를 유지하기 어렵다는 것을 반증하는 것이라고 할 수 있다. 특히 기존의 산업 중심의 정부지원 전략에서 기업중심의 정부지원 전략으로의 선회 경향은 산업의 주체는 기업이기 때문에 기업의 전체적 역량에 의한 경쟁우위가 글로벌 경쟁에서 보다 중요하다는 점을 시사하고 있다. 경남의 항공우주산업 클러스터 조성 여건은 인프라 구축면에서 여타 지역에 비해 매우 우수한 하부 기반을 구축하고 있어 클러스터 구축에 따른 효율성과 국제경쟁력 확보 가능성이 높다고 할 수 있다. 먼저, 클러스터 구축의 핵심이 되는 핵심선도기업인 KAI가 15년 전부터 대상지역에서 생산활동 중이며, 교육 및 훈련 기능도 비교적 풍부할 뿐만 아니라 공항도 인접해 있어 신속한 물류 및 정보공유, 해외시장과의 접근성이 높다고 할 수 있다. 결론적으로 볼 때, 경남지역의 항공우주산업 클러스터 구축의 타당성은 높다고 할 수 있다. 특히 현재의 항공우주산업 발전 단계상으로 볼 때, 부품산업의 발전이 긴요한 과제이므로 동 클러스터는 항공우주 부품 수출중심의 핵심 거점 클러스터로의 조성할 필요성이 높다고 할 수 있다. 이와 같은 클러스터 조성에 따른 경남 항공우주 클러스터의 운영체계는 “항공우주산업 혁신 클러스터 추진단”을 중심으로 입주 업체, 항공우주 수출 지원단, 관련 R&D 기관 및 교육기관 등이 긴밀하게 연계 되어 운영되어야 할 것이다. 이외에도 중앙정부와의 협의 및 관련 단체들과의 연계를 통해 클러스터의 효율성과 경쟁력 제고를 위한 활동을 적극 추진해야 할 것이다.

Today, there is in the world-wide cognition about RFID technology due to established standard, EPC(Electronic Product Code). RFID technology will have wide influence over various fields. Especially, RFID technology's advantages will have positive influence on logistics field. We can solve limited various problems presented in SCM by applying RFIB technology. We can have higher cantrol system, better benefits and actual decision information. Many organizations, however, still have hesitated now because RFID technology has not been validated and RFID technology is in early stage. Other problems are employee resistance against new technology and lack of academic empirical research on assimilation RFID technology for organization. Above reasons I mentioned make me study on analysis on assimilation RFID technology decision in SCM field. This study attempts to analyze the assimilation RFID technology factor from previous researches by using AHP. This outcomes of study will be helpful when we assimilate RFID technology in SCM fields.

Modern cities are changing to 'smart cities' dramatically with the introduction and development of the fourth industrial revolution technologies. Among these technologies blockchain is unique because it not only embraces technological innovation but also societal revolution. Therefore, blockchain is expected to play a pivotal role for contributing comprehensive development of smart city. The current research and policy atmosphere in Korea, however, is that blockchain is just a new technology and its broader impacts are overlooked. This study argues that blockchain has significant effects on smart cities not only from technological perspectives but also from social, economic, institutional, governmental perspectives. Further, this study suggests three categories that blockchain can help the development of smart city: technology, socio-economic, and governance, with examples of existing blockchin projects. However, these projects have been builting separately without any interaction under the common hood of 'smart city'. To emhance influences of blockchain on smart cities in positive ways, private companies, policy maker, and citizend are supposed to consider and discuss about publi sector's blockchain that is commonly used in at the smart city level.

The popularity of cloud computing has led to the emergence of various types of cloud services, and the hybrid cloud, a deployment model that integrates public cloud and private cloud and offset their shortcomings, is in the spotlight recently. However, the complexity of different clouds integration and the lack of related integration solutions have delayed the adoption of hybrid cloud and cloud strategy by companies and organizations. Therefore, in this paper, we propose a cloud integration mechanism to solve the integration complexity problem. The cloud integration mechanism proposed in this paper consists of integration script that solves the cloud integration by the script based on the hybrid cloud function, a process of creating and executing it, and a script creation model applying the software design pattern. By integrating the various cloud services, we can quickly generate scripts that meet the user's needs. It is expected that the introduction of hybrid cloud and the acquisition of cloud strategy can be accelerated through this proposed integration mechanism.

The Bass Diffusion Model is one of the most successful models in marketing research, and management science in general. Since its publication in 1969, it has guided marketing research on diffusion. This paper illustrates the usage of the Bass diffusion model, using mobile cellular subscription diffusion as a context. We fit the bass diffusion model to three large developed markets, South Korea, Japan, and China, and the emerging markets of Vietnam, Thailand, Kazakhstan, and Mongolia. We estimate the parameters of the bass diffusion model using the nonlinear least square method. The diffusion of mobile cellular subscriptions does follow an S-curve in every case. After acquiring m, p, and q parameters we use k-Means Cluster Analysis for grouping countries into three groups. By clustering countries, we suggest that diffusion rates and patterns are similar, where countries with emerging markets can follow in the footsteps of countries with developed markets. The purpose was to predict the timing and the magnitude of the market maturity and to determine whether the data follow the typical diffusion curve of innovations from the Bass model.

At the 104th IMO MSC, it was decided to make a code for the operation of MASS(Maritime Autonomous Surface Ship). In addition, the government announced a roadmap for preemptive regulatory innovation for autonomous ships and identified 31 related regulatory issues and suggested improvements to revitalize the autonomous ship industry. This study aims to analyze the ship turning left on the route as a study on how to operate the route system when operating MASS. We intend to derive the current congestion degree of the special area of Busan New Port through maritime traffic survey and use simulation to derive the congestion degree of the special area due to the size of ships and increase in traffic volume. We would like to propose an appropriate amount of traffic (the number of L-converted). It is believed that the research results can be used as basic data for route operation when operating not only current ships but also MASS.

Since 2000, Korea has seen a big trend in the market, as the EU tightened regulations on environment due to global warming, high oil prices and aging rural population distribution, strengthening the need for multi-purpose electric moto vehicles for small farmers based on eco-friendly energy. Multi-purpose electric motor vehicles for rural small businesses will be a very innovative means of transportation, not only maintained at a low cost and to reduce greenhouse gases through the activation of eco-friendly energy, but also be a very innovative means of transportation for reducing the labor intensity of the aging farming industry and transporting night work and logistics. In this paper, with the implementation of eco-friendly energy policies, small and medium-sized rural small business owners can easily operate on unpaved roads and well-drawn farming environments, while the intensity of labor can be reduced when transporting crops also can simply replace parts at a low cost in the event of an accident. To propose rural multi-purpose modular electric vehicles, the existing literature is reviewed and 12 modular parts are presented by benchmarking electric vehicles at home and abroad. This paper is thought to be helpful for the research of the industry as well as the design industry of modular electric vehicles.
