Gyeongnam province is well known for its high concentration on machinery manufacturing industry. However, this province is losing competitive advantage due to the lack of IT S/W industry. In this paper, we propose a way for adoption of u-Manufacturing technology to promote IT S/W industry in Gyeongnam. At first, we identified the needs of manufacturing companies and the capabilities of the IT S/W companies with survey. Based on the survey analysis, then we set up the u-Manufacturing concept and proposed Manufacturing IT middleware to support it. Finally, we proposed a strategy to promote smoothly the adoption of u-Manufacturing technology in this area.

유비쿼터스 시대에 즈음하여, 최근 생산 분야에서는 유비쿼터스 컴퓨팅 기술과 제조기술의 접목을 통해 제조 현장의 혁신을 가능케 하는 u-Manufacturing 패러다임이 주목 받고 있다. u-Manufacturing 환경의 구축을 위해서는 국제적 협업 환경에서 제품 확장 수명 주기 상의 자유로운 정보 수집 활동과 더불어, 생산 현장과 상위 시스템 간의 실시간 정보 교환이 주요 이슈로 대두된다. 본 논문에서는 u-Manufacturing 패러다임을 실현할 수 있는 방안으로서 RFID 기술을 활용한 생산 시스템을 아래의 연구를 통해 제시한다: (1) 생산 현장에서 RFID 기술 활용 시나리오와 RFID 기반 생산 시스템의 구조를 제안하고, (2) 이에 사용되는 정보를 국제 표준 규격(ISO 10303-239, ISO 15531 등)에 입각하여 모델링하고, (3) 프로토타입 구현을 통해 유효성을 검증한다.

This paper tried to analyze the collection and management method of shop-floor information for development of digital framework in u-manufacturing. In detail, the shop-floor information collection method through the direct communication with manufacturing devices using network Including RS-232C/422, field bus and ethernet is analyzed and proposed. In case the direct communication is impossible, the information collection method through additional sensors or data acquisition units is analyzed and proposed. Moreover, the collection method through bar code reader or touch screen of operators is analyzed and proposed to act up to machine to man/mobile/machine.

In the future, a machine will be more improved in the form of advanced concept with collaborative ability in M2M(Machine to Machine, Mobile to Machine) environment for u-Manufacturing system. This paper tried to standardize M2M and design advanced concept machine. The M2M is front-end system for implementing autonomous ubiquitous environment. The advanced machine in M2M will be a collaborative machine with knowledge-evolutionary ability such as u-Machine(Ubiquitous machine), Vortal(Vertical Portal) machine and P2P(Peer to Peer) machine. Such advanced concept machines will be the key subject for M2M cooperation.

Under the Manufacturing Liability Act, consumers want to be protected from manufacturers by mitigating burden of proof as an important target to be protected. However, due to the complexity of the product, it is very difficult for consumers to prove defects from the manufacturing defect. This situation has led to a major revision of the Manufacturing Liability Act, which mitigates the burden of proof of consumers by applying fruitless liability. The Manufacturing Liability Act is comparable to the U.S., which has strong consumer rights and is protected by the Manufacturing Liability Act. The burden of proof can be regarded as the most necessary content for consumers within the manufacturing product liability law when responding to manufacturing defects. The U.S. intends to provide implications for achieving consumer protection in Korea's Manufacturing Liability Act by imitating the U.S. based on the burden of proof. Case comparison regarding burden of proof can be conducted based on various criteria, including criteria for each product and key features for determining the importance of the manufacturing product liability law. The Act on the Responsibility of Korean Manufacturing Products for the Protection of Consumers was developed based on the assessment criteria, and a remedy was proposed to protect consumers who suffered from manufacturing defects.

This paper presents the optimal design reducing the rotor inertia in order to improve the driving characteristic of BLDCM for robots. The parallel Genetic Algorithm is performed to rotor inertia minimization in optimal design. Also, velocity profile with finite jerk method is introduced to reduce vibration of BLDCM. As a result, a torque characteristic is same although rotor inertia is reduced 2/3 compared with prototype model. And, maximum vibration value is reduced by 63.4[%1 according to apply finite jerk.

This paper empirically investigated whether the dependence of manufacturing firms effects the influence strategies and long-term orientation based on the data from manufacturing firms in Korea. U.S., and Japan. Also, the proposed model was proven by the structural equation model with the data gathered from 105 manufacturing firms in Korea, 103 in U.S., and 83 in Japan. The findings were as follows. First, the dependence of all of manufacturing firms, regardless of country, positively affected the coercive influence strategies of distributors, whereas the dependence positively affected the noncoercive influence strategies in U.S. and Japan but in the case of Korea, it showed the reverse direction and were not statistically significant. Second, the dependence of Korean manufacturing firms positively affected the long-term orientation but American manufacturing firms showed the reverse direction and it was not statistically significant. In the case of Japanese manufacturing firms, the direction predicted in the paper was shown but was not statistically significant. Third, the coercive influence strategies positively affected the long-term orientation in Korea but it showed the negative relationship in Japan. Fourth, the noncoercive influence strategies positively affected the long-term orientation in all countries. Lastly, a few implications, limitations and future study issues were discussed.

In recent years, developed and developing country such as U.S., Japan, and China push forward to enhance their manufacturing industry through national policies such as advanced manufacturing(U.S.), Industrie 4.0 (Germany), and Made in China 2025. Also, in Korea, Ministry of Trade, Industry, and Energy(MOTIE) claimed Manufacturing3.0 for encouraging domestic manufacturing industry. Manufacturing industry plays an important role in encouraging economy and employment. In this paper, we survey, analyze and summarize the current national policy for enhancing manufacturing industry.
