  • The neural network method has been introduced to design a controller for linear motor feed system and system operation status was monitored. It is most difficult to achieve controller gain tuning because of the information limit. Regardless of the system structure, conventional control gain could be adjusted minimizing the resulting error for both position and velocity using the proposed method. Slight performance deterioration was observed at the small value of training epoch. Different controller performance for position was observed with respect changed sampling time. Actuated system performance was monitored using neural network signal processing and operational status was predicted with the rate of 80% approximately.

  • Factory monitoring systems are gaining importance in wide areas of industry. Especially, there have been many efforts in implementation of vibration measurement and analysis for monitoring the status of rotating machines. In this paper, a digital signal processor (DSP) based monitoring system dedicated to the vibration monitoring and analysis on rotating machines is discussed. Vibration signals are acquired and processed for the continuous monitoring of the machine status. Time domain signals and fast Fourier transform (FFT) are used for vibration analysis. All of the signal processing procedures are done in the DSP to reduce the production and maintenance cost. The developed system could also provide remote and mobile monitoring capabilities to operator via internet connection. This paper describes the overview of the functional blocks of the implemented system. Test results based on signals from small-size single phase motors are discussed for monitoring and defect diagnosis of the machine status.

  • The purpose of this study is to examine the disaster management system of local governments by diagnosing the current status of disaster management experts in Korea, deriving problems and improvement measures, and looking at local governments' total labor cost system. The status and status of disaster management personnel were compared and analyzed to find ways to improve the local government's disaster management response system under the Framework Act on Disaster and Safety Management in Korea. Considering Korea's reality, because national security and disaster management exist together, we devised a plan to improve on-site response capabilities and seek solutions by deriving the problems of the currently operating security and safety-related organizations.

  • The degree of doctors' autonomy is decided by the relations between the profession and the state. The exclusive right required by doctors is based on knowledge, but it is most often decided by the relations between the profession and the state. The critical factor affecting the status of the medical profession is the span of its control on medical related areas. Therefore, the status of doctors depends on the degree of institutionalization and the span of their control. The status of Korean Oriental Medicine doctors has been largely affected by the governments medical policies. The dramatic change of the status of Korean Oriental Medicine in modern Korea dearly shows the effects of medical policy on the status of a medical system. Under the plural medical system every medical group lobbies for more favorable medical policies. Korean Oriental Medicine doctors have secured an enhanced status in government and expanded the range of medical insurance coverage. Also, they have accomplished the standardization of knowledge in their efforts to expand it. These achievements are the most important aspects of the professionalization of Korean Oriental Medicine. Therefore, we can conclude that the conflicts between Korean Oriental Medicine doctors and government representatives have had significantly positive effects on the professionalization of Korean Oriental Medicine.

  • It have been known that the probability of accidental happening in towing-barge is higher than that of other merchant vessels. Because the towing-barge is restricted in thier manoeuvring ability due to its towingline. A report from ministry maritime affairs and fisheries said that the rate of collision accident for towing-barge is $40\%$ high tlnn other transport system in sea. A number of researches have been carried out to improve the safety policy in the towing-barge sea transportation system by the gorvernment. This study examined the safety status in domestic towing-barge sea transportation system The registration status, safety operational policy and post accidental data were also examined A survey research of experts relating to towing-barge operation also was carried out to find the detailed of safety status. This study would be applicable to set up safety policy for towing-barge marine transportation system.

  • To operate Platform Screen Door (PSD) automatically, the operational data of PSD and the train must be interfaced properly. PSD and train are operated together by the signaling system in Automatic Train Operation (ATO) signaling system zone where interfaces are provided between PSD and train. However, the additional PSD interface system with train is required in train operating zone without the interface between PSD and train. For the PSD interface, the wireless communication system or the train status (train correct stop status / train door status) detection system has been used. Seoul Metro line No.2. has the PSD wireless communication system using 447MHz band RF. For the safety of PSD operation, it is required to prevent RF interference in the subway environment where many frequencies exist. In this paper, the PSD wireless communication system is developed using 2.4GHz band RF to prevent the interference of the wireless communication and increase the traffic of the PSD interface. Furthermore, the improved system can store, manage and display the PSD and train operational data using Human Machine Interface (HMI) in the train's driver cab.

  • This paper analyzes the current state of operation and the effect of introduction of the single accreditation system, which was fully introduced in 2016 by the Accreditation Board of Engineering Education Korea(ABEEK). Because Engineering Education Accreditation are program-based certification, and department operates accreditation programs and non-accreditation programs, if a student under the accreditation program fails to graduate from the accreditation program, he or she must complete the transfer to a non-accreditation program at least one year before graduation. Since 2016, when the single accreditation system was introduced, freshmen of department have allowed non-accreditation graduation only for reasons prescribed separately by the program's regulations or guidelines. In order to identify and reflect the operational status and effectiveness of the single accreditation system in the 2020 accreditation review, ABEEK conducted a complete survey on the current status of graduates in February 2020 among 157 programs at 26 universities receiving the 2020 accreditation review. The results of this study are expected to be used as basic data for the improvement of the single accreditation system in the future by examining the effects of the single accreditation system implemented after 2016 and considering the problems at the site due to the introduction of the single accreditation system of programs that ABEEK had not previously expected.

  • On this paper, we proposed a design rule of charger monitoring system which allow us to watch the charging status and verify it for building the electric chargers infrastructure by spread of electric vehicle. Gathering the charging status of battery by proposed system makes us to enhance the charging algorithm, to interface with BMS(Battery Management System) of electric vehicle, to control the charging process with users. Because the technology of rapid charging is dependant upon various factors such as a performance and stability of battery. We proposed the monitoring system of rapid charger based on CAN protocol that can watch a working status of rapid charger including the charging status of battery with real time and can reduce the charging time of battery with optimized status. We also implement it and evaluate its performance.
