Electrical motors are an integral part of industrial plants with no less than 5 billion motors built word wide every year and the BLDC motor have been increased demand on industrial application. This paper presents BLDC motor control algorithm for cost effective motor application using general purpose microprocessor which have only one on-chip timer and describes how to realize pulse width modulation(PWM) signals with general input/output(I/O) ports to control a three-phase permanent magnet brushless do motor using timer interrupt on MSP430F1232.

This research relates to the patent application tendency about the components and modules of the intelligent robot among the robotics industry in which the market is more and more expanded. The patent about the components and modules of intelligent robot was analyzed from not only Korea but also U.S, Japanese and Europe which is called as the 3 pole of patent. By this research the government which supervises the nation's research policy can obtain the objective information of the industrial tendency, so it can establish the investment policy of national research and development. And the researchers can set up the research direction for evasion from patent infringement trouble by obtaining the patent application information. This also shows whether their research can be competitive or not.

It is necessary to improve the time efficiency in the high power testing station because tests are mainly performed by high-priced equipment. Minimizing a human error through building the database of relevant standards is possible to expect reliable tests. And also, application program that is properly customized for the certain laboratory's power system will help test engineer to easily analyze the phenomenon that is happened in short-circuit and load switching tests. This paper introduces the several functions of the application program that is developed in order to realize these requirements.

In this paper, we propose a reference model for logistics processes to improve the effect of RosettaNet standards application to domestic industry. First of all, implementation cases applied to logistics processes in the world are investigated. Second, logistics processes of domestic manufacturers are analyzed for the application of RosettaNet standards, and the processes are compared with PIP. Finally, a new logistics processes model and corresponding PIP documents which reflect domestic situations are proposed.

선박건조에 있어서 대형 블록의 조립이 이루어지는 선행 탑재 및 탑재 단계에서 Tank Top과 Upper Deck의 V 개선 용접은 FCAW+SAW의 복합용접이 실시되고 있다. 그러나 가장 범용적 모재 두께인 18~20t의 경우 SAW 시공에만 약 5~6Pass가 소요됨으로써 다급한 진수 일정에 많은 지장을 초래하고 있다. 또한 능률 향상을 목적으로 용착량 증가효과를 얻기 위해 철분말이나 절선와이어를 개선면내에 충진하고 용접을 수행하나 획기적인 용접능률을 기대하기 어렵고 용접사 기량에 따라 용접 결함이 발생될 수 있다. 이에 따라 용접패스 수를 줄이고 결함 발생이 없는 용접기법 개발이 절실히 필요하였다. 이를 위해 매우 간단하고 효율적인 위빙장치를 제작하여 선탑/탑재 아래보기 용접이음에 1~2패스의 SAW 용접법을 개발하여 용접생산성은 물론 용접품질까지 획기적으로 향상시키는 기술 개발을 완료하였다.

In this study, we propose an RFID based container terminal operation process. Field tests are conducted for 900 MHz (truck identification) tag and 433 MHz RFID (container identification/e-seal) tag at an Incheon container terminal to verify possibility of applying RFID in the container terminal gate. To evaluate effect of applying RFID in the container terminal operation, simulation models for current and RFID based container terminals are developed using ARENA. Simulations are carried out using industrial field data and the result indicates that performance of the container terminal can be prominently improved after RFID application.

This study examines the effects of supply chain search and application strategies on organizational capability and corporate operational performance. To achieve this aim, a survey was administered to middle managers of 298 small- and medium-sized venture companies in Busan, South Korea. Empirical analysis showed that supply chain search and application strategies have a positive effect on organizational capability and corporate operational performance. In addition, organizational capability is positively mediated by supply chain search and application strategies in terms of the mediating effect of corporate operational performance. Consequently, search and application as supply chain strategies are facilitating factors as mediators that improve corporate performance through the concentration of organizational capability. Findings suggest that the search and application of supply chain strategies need to act as accelerating variables that improve organizational performance, and supply chain strategies need to be applied in small- and medium-sized manufacturing businesses.
