It is inevitable for local systems to have deviations which represent interactions and modeling errors originated from the decomposition process of a large scale system. This paper presents a decentralized control scheme for interconnected systems using local linear models and a neuro-coordinator. In the proposed method, the local system is composed of a linear model and unknown deviations caused by linearizing the subsystems around operating points or by estimating parameters of the subsystems. Because the local system has unmeasurable deviations we define a local reference model which consists of a local linear model and a neural network to estimate the deviations indirectly. The reference model is reformed into a linear model which has no deviations through a transformation of input variables and we obtain an optimum feedback control law which minimizes a local performance index. Finally, we derive a decentralized feedback control law which consists of local linear states and neural network outputs. In the decentralized control, the neuro-coordinator generates a corrective control signal to cancel the effect of deviations through backpropagation learning with the errors obtained from the differences of the local system outputs and reference model outputs. Also, the stability of local system is proved by the degree of learning of the neural network under an assumption on a neural network learning index. It is shown by computer simulations that the proposed control scheme can be applied successfully to the control of a biased two-link planar robot manipulator.

본 논문에서는 예상 위치좌표 탐색기법과 이를 균등거리비율 개념인 AEDR(Algorithm for localization using the concept of Equivalent Distance Rate)에 적용한 위치인식 보정 알고리즘인 E&E(Equivalent distance rate & Estimated location coordinator exploration)를 제안 한 후 실험을 통해 성능을 분석하였다. 실험결과, E&E는 4개의 시나리오에서 SDS-TWR의 위치인식 보정성능을 0.60m에서 0.34m로 0.26m 만큼 향상시켰고, E&E는 설정된 시나리오에 따라 기존에 제안된 AEDR과 비교한 결과 위치인식 보정 성능비율이 최대 15% 만큼 우수함을 확인하였다. 또한 E&E의 전체 성능실험 중 99%에서 위치인식 오차가 1m 이내로 측정되었는데 이 정도의 위치인식 보정 성능이라면 제안하는 알고리즘인 E&E는 다양한 위치인식 응용분야에 충분히 적용 가능 할 것으로 판단된다.

Objectives: This study was conducted to investigate general characteristics, job characteristics, characteristics of hospitals, and hospital coordinators, and to investigate the factors affecting the job satisfaction of medical workers. Methods: The data was collected through a self-reported questionnaire among 435 workers in plastic surgery and dermatology clinics in metropolitan city G. We investigated general characteristics, job-related characteristics, characteristics of medical institutions and hospital coordinators, job performance of hospital coordinators, and job satisfaction of medical workers. T-tests, ANOVA, correlation, and multiple regression analyses were conducted to investigate the factors related with job satisfaction. Results: The job satisfaction of the medical workers and the perceived job performance of hospital coordinators were $3.55{\pm}0.40$ and $3.74{\pm}0.43$, respectively. In multiple regression analysis, drinking frequency, number of night shifts, number of work days, and hospital coordinator introduction years were associated with the job satisfaction of medical workers. The more the overall job performance of hospital coordinators increased, the higher was job satisfaction(B=0.458, p<0.001). In detail, the more job roles(B=0.218, p<0.001), core competency(B=0.145, p=0.005), and leadership(B=0.099, p=0.037) increased, the higher was the job satisfaction of medical workers. Conclusions: The job satisfaction of the medical institution workers was associated with the perceived job performance of the hospital coordinator. In order to increase the job satisfaction of medical institution workers, a hospital coordinator with specialized job performance will be able to improve job satisfaction by carrying out efficient work in the medical institution.

This paper proposes a new network coordinator node design to select the most suitable wireless technology for WBANs by using fuzzy logic. Its goal is to select a wireless communication technology available considering the user/application requirements and network conditions. A WBAN is composed of a set of sensors placed in, on, or around human body, which monitors the human body functions and the surrounding environment. In an effort to send sensor readings from human body to medical center or a station, a WBAN needs to stay connected to a local or a wide area network by using various wireless communication technologies. Nowadays, several wireless networking technologies may be utilized in WLANs and/or WANs each of which is capable of sending WBAN sensor readings to the desired destination. Therefore, choosing the best serving wireless communications technology has critical importance to provide quality of service support and cost efficient connections for WBAN users. In this work, we have developed, modeled, and simulated some networking scenarios utilizing our fuzzy logic-based NCN by using OPNET and MATLAB. Besides, we have compared our proposed fuzzy logic based algorithm with widely used RSSI-based AP selection algorithm. The results obtained from the simulations show that the proposed approach provides appropriate outcomes for both the WBAN users and the overall network.

Path planning is an important task for optimal motion of a robot in structured or unstructured environment. The goal of this paper is to plan the shortest collision-free path in 3D, when a robot is navigated to pick up some tools or to repair some parts from various locations. To accomplish the goal of this paper, the Path Coordinator is proposed to have the capabilities of an obstacle avoidance strategy[3] and a traveling salesman problem strategy(TSP)[23]. The obstacle avoidance strategy is to plan the shortest collision-free path between each pair of n locations in 2D or in 3D. The TSP strategy is to compute a minimal system cost of a tour that is defined as a closed path navigating each location exactly once. The TSP strategy can be implemented by the Neural Network. The obstacle avoidance strategy in 2D can be implemented by the VGraph Algorithm. However, the VGraph Algorithm is not useful in 3D, because it can't compute the global optimality in 3D. Thus, the Path Coordinator is proposed to solve this problem, having the capabilities of selecting the optimal edges by the modified Genetic Algorithm[21] and computing the optimal nodes along the optimal edges by the Recursive Compensation Algorithm[5].

This paper presents a concurrent channel time allocation scheme used in the reservation period for concurrent transmissions in 60-GHz wireless personal area networks (WPANs). To this end, the proposed resource allocation scheme includes an efficient method for creating a concurrent transmission group by using a table that indicates whether individual streams experience interference from other streams or not. The coordinator device calculates the number of streams that can be concurrently transmitted with each stream and groups them together on the basis of the calculation result. Then, the coordinator device allocates resources to each group such that the streams belonging to the same group can transmit data concurrently. Therefore, when the piconet coordinator (PNC) allocates the channel time to the individual groups, it should allow for maximizing the overall capacity. The performance evaluation result demonstrates that the proposed scheme outperforms the random grouping scheme in terms of the overall capacity when the beamwidth is $30^{\circ}C$ and the radiation efficiency is 0.9.

Objective : To explore and describe coordinators' experiences in collaborative practices between the traditional Korean medicine doctors and the western medicine doctors. Methods : Five coordinators who agreed and completed the informed consent to take part in this qualitative study were interviewed thoroughly and tape-recorded. Transcribed data were analysed thematically with ground theory. Results : Most participants started their coordinating work without sufficient knowledge and systemic support. They, however, could find their identity as coordinators for collaborative practices through preparing manuals and protocols, providing comprehensive patients care, and experiencing the partnership with doctors. To coordinate Korean medicine and western medicine practices efficiently, participants have tried to enhance their professional knowledge and skills, and establish favorable networks. On the other hand, they were in dilemmas of being a multi-player and imbalance of responsibilities and powers in their jobs. Conclusions : It is recommended to clarify job description of coordinator for collaborative practices, develop training programme, and provide the institutional support for wider recognition of coordinator. Findings from this study should be considered in both Korean medicine-western medicine collaborative research and practice.
