Surgical reconstruction of fractured extremities is a complex procedure that orthopaedic residents must master during training. Currently, training is based on an apprenticeship model, which while beneficial, is not uniform and does not provide any means to assess skills competency. Surgical simulation can help address shortcomings in the training model by providing residents opportunities to (...

BACKGROUND Survival and freedom from disability are arguably the most important patient-centered outcomes after surgery, but it is unclear how postoperative disability should be measured. The authors thus evaluated the World Health Organization Disability Assessment Schedule 2.0 in a surgical population. METHODS The authors examined the psychometric properties of World Health Organization Dis...

Excessive ordering of blood components causes problems such as a lack proper distribution products between centers, increased costs, and workload banks. Effective use MSBOS will reduce the cross-match patient samples unnecessary testing. This is also expected way to improve quality health services at UNAIR Hospital treatment costs. study aimed find out profile for orthopedic surgery in period J...

We focus on the integrated seaside operations in container terminals, namely the integration of berth allocation, quay crane assignment and quay crane scheduling problems. We first develope a mixed-integer linear programming formulation. Then, we propose an efficient cutting plane algorithm based on a decomposition scheme. Our approach deals with berthing positions of the vessels and their assi...

The number of minimally invasive cardiological interventions has increased over the last few years and therefore computer based training systems find growing interest. They offer a better learning schedule compared to traditional master-apprentice models due to the repeatability of the learning situation and the possibility to learn individual tasks. Below we present the research system CathI t...

This paper deals with constraint handling in manufacturing. It starts with a basic de nition of the constraint satisfaction problem, followed by a description of consistency enforcing and constraint guided search. Constraint handling in scheduling problems is the main topic of the paper also presenting di erent types of schedule construction methods and explaining the use of temporal constraint...

Simulation is useful for the evaluation of a Master Production/distribution Schedule (MPS). Also, the goal of this paper is the study of the design of a simulation model by reducing its complexity. According to theory of constraints, we want to build reduced models composed exclusively by bottlenecks and a neural network. Particularly a multilayer perceptron, is used. The structure of the netwo...

Round addition differential fault analysis using operation skipping for lightweight block ciphers with on-the-fly key scheduling is presented. For 64-bit KLEIN, it is shown that only a pair of correct and faulty ciphertexts can be used to derive the secret master key. For PRESENT, one correct ciphertext and two faulty ciphertexts are required to reconstruct the secret key. Furthermore, secret k...

This paper describes the equipment assignment in a control recipe design. To produce a batch in a batch plant, equipment assignments to each task of a batch are carried out on the basis of the equipment requirement information of the master recipe. However, the equipment units satisfying the equipment requirement are not necessarily connected topologically with each other, especially in the mul...
