  • This paper describes the real-time data linkage of the field control system for distributed control in nuclear power plant environment. The most important keys of digital control system in nuclear power plant are the reliability and stability of system, and real-time control ability. This Paper brought up the hardware construction using a new method about the design of each station located upon control transmission network to improve real-time ability of field control system, and measured the station binding time between devices connected to field control module. And it was confirmed performance improvement of overall system for real-time data linkage between control devices.

  • An actuator should be added to a existing control linkage to make manned aircraft to unmanned. But it is quiet difficult to synchronize actuator with control surface because non-linear error necessarily occurs when four-bar linkage acts in three dimensional motion. In addition, in point of controller design view, while a real-time model needs the control surface deflection as its input, controller needs the actuator command as its output. Hence, the relation between both should be investigated. In this paper, the mathematical relation between actuator and control surface deflection investigated by kinematic analysis of a plant aircraft. The performance margin of the selected actuator also was verified.

  • Magnetic coupling delivering wireless power in capsular endoscope(CE) is described in this paper. The characteristic of the magnetic flux linkage coil which generates the induced electromotive force(emf) under the magnetic field was analyzed. With the analyzed results, a magnetic flux linkage coil system was developed and tested. It was confirmed that the magnetic flux linkage coil system could supply more than 50 mW power at 125 kHz without changing the structure of conventional CE.

  • It is a superordinate concept to a network control system which optimally distributes the battery power to overall length parts through the linkage control drive and absorbs/integrates network diagnostics and overlapped functions with overall length control systems. This study is to develop a system that maximize the battery power and motor effectiveness by controlling motor battery controlling module with common MCU Integration linkage controlling system, and to develop S/W and H/W that can be controlled by linked with each controlling module in CAN method through using Autosar's standardized software.

  • Recently, there has been a noticeable increase in the number of tourists in islands that are well-known for their natural landscapes. It is expected that this number will go up steadily, due to the increase in per capita income and leisure time. Regarding tourism transportation, utilizing linkage transport between coastal passenger terminal and inland transport system is crucial. However, the existing system does not measure up to the expectations. This is attributable to the fact that the distances between coastal passenger terminals and inland transportation terminals are too far. Also, the current public transportation system lacks support and needs to take the role of connecting the two terminals. This study shows how coast-inland linkage transport system should be reformed in order to promote island tourism. It focuses on building linkage transport system and minimizing walking distance. Also, adjusting passenger ship schedule to the characteristics of island tourism is needed. For the sake of passengers, coastal passenger ship fare should be reduced, and integrated transport information should be provided.

  • Purpose: The purpose of this study was to identify NANDA, NIC, and NOC frequently used and their linkages in major nursing departments for development of the nursing process and nursing management system. Methods: This study was a descriptive study. Data were collected from 123 nurses who worked in medical, surgical, pediatric, gynecologic, and psychiatric department. The questionnaire was based on the NANDA, NOC, NIC, and NANDA-NOC-NIC linkage system. This research was analyzed by an EXCEL program and SPSS $Pc^{+}15.0$. Results: Nursing diagnoses frequently used were 'anxiety', 'disturbed sleep pattern', 'activity intolerance', 'social isolation', 'nausea', 'ineffective airway clearance', 'chronic pain', nursing outcomes frequently used were 'thermoregulation', 'bowel elimination', 'pain control', 'vital sign status', 'pain level', and nursing interventions frequently used were 'nausea management', 'airway suctioning', 'bowel elimination management', 'diarrhea management', 'medication management'. NANDA-NOC-NIC linkages in major nursing departments were recognized, and these results were similar to the results of other researches. Conclusion: The results of this study will be provided as a guideline to apply to the nursing process and development of the nursing process system with the NANDA-NOC-NIC linkage in major nursing department.

  • Violence against women includes sexual violence, domestic violence, trafficking, etc. It is a serious problem that violates women's rights and basic freedom. In Korea, with the enactment of the laws on sexual violence and domestic violence in the 1990s, counseling centers and protective facilities for the victims began to be established and have been rapidly increasing in number recently. The purpose of this research was to investigate the current status of the counseling services with a focus on their linkage function. 78 out of 109 counselors working in the counseling centers for sexual and domestic violence throughout Korea responded to a mail survey. The questions included the general characteristics of the centers and the counselors, the structural, relationship and process dimensions of linkage function, and the subjective and objective aspects of the degree of linkage. The findings of the analysis highlighted the following problems. First, the counseling centers played limited role in serving the victims of violence due to lack of resources in the service network. Second, the linkage of services existed on a relatively small scale which was mostly based upon informal and unstructured relationship. Third, according to the multivariate analysis, the existence of potential partner agencies, the effort of the line staff to initiate the linkage relationship and mutual cooperation between agencies determined the degree of linkage among services. These findings suggest implications for establishing a more effective system to protect the victims of violence.

  • In this paper, the feasibility of the high-performance damping device vibration suppression of stay cables has been investigated. The proposed damping system consists of a linear viscous damper and a scissor-jack-type toggle linkage. Since the mechanism of the scissor-jack-type toggle linkage amplifies the relative displacement of the linear viscous damper, it is expected that the capacity of the viscous damper used in the scissor-jack-damper energy dissipation system can be reduced without the loss of the control performance. Numerical simulation results demonstrate the efficacy of the damping system employing the scissor-jack-type toggle linkage. Therefore, the proposed damping system could be considered as one of the promising candidates for suppressing vibration of stay cable.
