Objective: To evaluate the effect of implementing a Caring Model on patient satisfaction. Background: Patient satisfaction has become an important indicator of quality care and financial success of healthcare institutions. Acknowledging the importance of nurse caring behaviors and the impact on patient satisfaction has been relatively recent. Based on a synthesis of the literature, five caring behaviors have been formulated into a model; no single study identified the five selected behaviors included in this study. Methods: In an acute care setting, eight patient satisfaction attributes were incorporated into a Caring Model. Implementation of the model among nursing staff members included an educational in-service, printing of the behaviors on the name badge, reminders in monthly staff meetings and nursing rounds, and inclusion of the caring behaviors in patient care documentation, job descriptions, and performance appraisals. The impact upon patient satisfaction was compared 6 months' preintervention to 6 months' postintervention. Results: Postintervention, the patient satisfaction attributes of Nurses Anticipating Needs and Responds to Requests significantly increased. Attributes that began preintervention as immediate priorities for improvement became major strengths postintervention. Conclusions/Implications: Results of this study provide evidence that nurse caring behaviors can influence patient satisfaction. For a Caring Model to be effective, it must become an integral part of strategic planning and be implemented throughout the entire organization. To sustain the effects of the model, there must be frequent reminders among staff members. Nurse caring is an important predictor of patient satisfaction. The authors discuss the effect of implementing a caring model on patient satisfaction. In an acute care setting, eight patient satisfaction attributes incorporated into five nurse caring behaviors were evaluated pre- and postintervention. Results of the study...

An on-line fault detection and isolation technique is proposed for the diagnosis of rotor vibration. The architecture of the systems mainly consists of feature generation and fault inference. A signal-based method is used for generating the features required by the subsequent neural fuzzy inference. In the signal-based approach, both lateral and axial vibration data are used for calculating signal features such as the average, the standard deviation, the maximum, and the harmonic multiples. A neural fuzzy network is exploited for intelligent inference of faults based on the extracted features. The proposed systems are implemented on the platform of a digital signal processor. Experiments carried out for a rotor kit, a centrifugal fan, and a centrifugal pump indicate the potential of the proposed techniques in predictive maintenance.

Motion recognition has received increasing attention in recent years owing to heightened demand for computer vision in many domains, including the surveillance system, multimodal human computer interface, and traffic control system. Most conventional approaches classify the motion recognition task into partial feature extraction and time-domain recognition subtasks. However, the information of motion resides in the space-time domain instead of the time domain or space domain independently, implying that fusing the feature extraction and classification in the space and time domains into a single framework is preferred. Based on this notion, this work presents a novel Space-Time Delay Neural Network (STDNN) capable of handling the space-time dynamic information for motion recognition. The STDNN is unified structure, in which the low-level spatiotemporal feature extraction and high-level space-time-domain recognition are fused. The proposed network possesses the spatiotemporal shift-invariant recognition ability that is inherited from the time delay neural network (TDNN) and space displacement neural network (SDNN), where TDNN and SDNN are good at temporal and spatial shift-invariant recognition, respectively. In contrast to multilayer perceptron (MLP), TDNN, and SDNN, STDNN is constructed by vector-type nodes and matrix-type links such that the spatiotemporal information can be accurately represented in a neural network. Also evaluated herein is the performance of the proposed STDNN via two experiments. The moving Arabic numerals (MAN) experiment simulates the object's free movement in the space-time domain on image sequences. According to these results, STDNN possesses a good generalization ability with respect to the spatiotemporal shift-invariant recognition. In the lipreading experiment, STDNN recognizes the lip motions based on the inputs of real image sequences. This observation confirms that STDNN yields a better performance than the existing TDNN-based syst...

This article presents the design and prototype implementation of a fault detection and fault tolerance facility based on the reactive system model for a loosely integrated heterogeneous database system running on a network of workstations. The database system consists of a number of fully autonomous databases that, through their willingness, can share some portion of their information. Sensors (functions that expose some part of the state of an object) are placed on individual databases and system objects (such as traders, agents, and other sensors). Other databases and system objects, and applications can subscribe to a sensor and therefore are notified whenever the sensor value changes. The fault detection mechanism uses sensors to monitor individual databases and system objects and to detect database or system faults. The fault tolerance mechanism uses actuators (functions that can change the state of an object) to react on database or system faults.

This paper addresses the problem of building reliable computing programs over remote procedure call (RPC) systems by using replication and transaction techniques. We first establish the computational model: the RPC transactions. Based on this RPC transaction model, we present the design of our system for managing RPC transactions in the replicated-server environment. Finally we present some results of a correctness study on the system and two examples of the system.

Replica control protocols in distributed database systems are responsible for the management and maintenance of replicated (redundant) data. Maintaining replicated data improves performance and increases availability. Keeping the replicated data consistent and available during the presence of failures can however become quite difficult. This paper presents the design of a hybrid replica control protocol that attempts to maximise availability and minimise communication overhead, by combining the advantages of two common replica control protocols into one. The protocol was simulated using SimJava, a process-based discrete event simulation package. The results from the simulations showed that not only did the hybrid algorithm maintain a high level of availability, it did so while minimising communication overheads.

© Springer-Verlag Berlin Heidelberg 1999. This paper investigates simple well behaved syntactic methods to fuse prioritized knowledge bases which are semantically meaningful in the frameworks of possibility theory and of Spohn’s ordinal conditional functions. Different types of scales for priorities are discussed: finite vs. infinite, numerical vs. ordinal. Syntactic fusion is envisaged here as a process which combines prioritized knowledge bases into a new prioritized knowledge base, and thus allows for subsequent iteration. Several fusion operations are proposed, according to whether or not the sources are dependent, or conflicting, or sharing the same scale.

This paper investigates simple syntactic methods to revise prioritized belief bases, that are semantically meaningful in the frameworks of possibility theory and of Spohn's ordinal conditional functions. Here, revising prioritized belief bases amounts to conditioning a distribution function on interpretations. Different types of scales for priorities are discussed: finite vs. infinite, numerical vs. ordinal. Syntactic revision is envisaged here as a process which transforms prioritized belief bases into a new prioritized belief base, and thus allows for the subsequent iteration.

This paper addresses the control problem of the six-degree-of-freedom parallel manipulator known as the Stewart platform. This manipulating structure has been well-known for its use as a flight simulator. Recently, it has become an important element in virtual reality (VR) applications for providing motion sensation to users. In this research, we first analyze the hydraulic driving system and the kinematics of the Stewart platform. We then develop a fuzzy controller for the Stewart platform. The stability of the proposed fuzzy control systems are analyzed based on the Popov criterion stability theorem. Experimental results have shown that the designed fuzzy controller can drive the six-degree motion platform accurately, smoothly, and stably.

© 1999 IEEE. Open systems are being presented as the way forward for the construction of complex computer based systems of all types. They have had some success but as with all such attempts to solve problems in computing, it is being touted as a panacea. Before the success is lost in disgruntled disappointment, this reflection attempts to establish awareness of pitfalls which may save the open systems idea from going the way of all panaceas. This paper further suggests that open systems are only, the first step towards safe and reliable computing platforms for the future, and recommends an evolutionary path which includes such concepts as stable infrastructure architectures, domain and application openness and open systems engineering.

© Springer-Verlag Berlin Heidelberg 1999. In this paper, we identify that failure to cater for the various forms of heterogeneity is one of the major drawbacks of the previous research on multi-agent belief revision(MABR). Three major categories of heterogeneity, namely social, semantic and syntactic heterogeneity are clarified. Several issues posed by such heterogeneities are addressed in the context of BR. The use of ontology is proposed as a powerful tool to tackle the heterogeneity issues so as to achieve the necessary reliable communication and system interoperability required by MABR. The question of what kind of ontology would be suitable to support MABR in a heterogenous setting is answered in Part I. In its sequel, Part II, a general framework for MABR is presented based on a shared knowledge structure which serves as the theoretical basis for ontology design.
