A quality improvement project using a problem based post take ward round proforma based on the SOAP acronym to improve documentation in acute surgical receiving

Objectives: Ward round documentation provides one of the most important means of communication between healthcare professionals. We aimed to establish if the use of a problem based standardised proforma can improve documentation in acute surgical receiving. Methods: Gold standards were established using the RCSE record keeping guidelines. We audited documentation for seven days using the following headings: patient name/identification number, subjective findings, objective findings, clinical impression/diagnosis, plan, diet status, discharge decision, discharge planning, signature, and grade. After the initial audit cycle, a ward round proforma was introduced using the above headings and re-audited over a seven day period. Results: The pre-intervention arm contained 50 patients and the post intervention arm contained 47. The following headings showed an improvement in documentation compliance to 100%: patient name/identification number vs 96%, subjective findings vs 84%, objective findings vs 48%, plan vs 98%, signature vs 96%, and grade vs 62%. Documentation of the clinical impression/diagnosis improved to 98% vs 30%, diet status rose to 83% vs 16%, discharge decision to 66% vs 16%, and discharge planning to 40% vs 20%. Conclusions: Standardised proformas improve the documentation of post-take ward round notes. This helps to clarify the onward management plan for all aspects of a patient's care and will help avoid adverse events and litigation. This should improve the quality and safety of Patient Care

Information-Theoretically Secure Voting Without an Honest Majority

We present three voting protocols with unconditional privacy and information-theoretic correctness, without assuming any bound on the number of corrupt voters or voting authorities. All protocols have polynomial complexity and require private channels and a simultaneous broadcast channel. Our first protocol is a basic voting scheme which allows voters to interact in order to compute the tally. Privacy of the ballot is unconditional, but any voter can cause the protocol to fail, in which case information about the tally may nevertheless transpire. Our second protocol introduces voting authorities which allow the implementation of the first protocol, while reducing the interaction and limiting it to be only between voters and authorities and among the authorities themselves. The simultaneous broadcast is also limited to the authorities. As long as a single authority is honest, the privacy is unconditional, however, a single corrupt authority or a single corrupt voter can cause the protocol to fail. Our final protocol provides a safeguard against corrupt voters by enabling a verification technique to allow the authorities to revoke incorrect votes. We also discuss the implementation of a simultaneous broadcast channel with the use of temporary computational assumptions, yielding versions of our protocols achieving everlasting security

Quantum Cryptography Beyond Quantum Key Distribution

Quantum cryptography is the art and science of exploiting quantum mechanical effects in order to perform cryptographic tasks. While the most well-known example of this discipline is quantum key distribution (QKD), there exist many other applications such as quantum money, randomness generation, secure two- and multi-party computation and delegated quantum computation. Quantum cryptography also studies the limitations and challenges resulting from quantum adversaries---including the impossibility of quantum bit commitment, the difficulty of quantum rewinding and the definition of quantum security models for classical primitives. In this review article, aimed primarily at cryptographers unfamiliar with the quantum world, we survey the area of theoretical quantum cryptography, with an emphasis on the constructions and limitations beyond the realm of QKD.Comment: 45 pages, over 245 reference

Vector plotting as an indication of the approach to flutter

A binary flexure-torsion analysis was made to check theoretically a method for predicting flutter which depends on plotting vectorially the amplitudes of response relative to the exciting force and extracting the relevant damping rate. The results of this calculation are given in graphs both of the vector plots themselves and of the estimated damping rate against forward speed. The estimated damping rates are compared with calculated values. The method has the advantage that in a flight flutter test damping can be estimated from continuous excitation records: the method is an extension of the Kennedy and Pancu technique used in ground resonance testing

Russia and the World Trade Organization: Will TRIPS Be a Stumbling Block to Accession?

Arbetet som presenteras i denna rapport har utförts på R1K, vilket är en avdelning på Rönnskärsverken, som är en del av New Bolidens koncern. 2007 byggdes ett nytt gassystem med ett flertal nya komponenter. Till detta gassystem fanns bristande information om hur dessa komponenter fungerar och hänger ihop. Detta examensjobb har till syfte att skapa en funktionsbeskrivning i form av en lättläst operatörsmanual, för nya och erfarna operatörer. Informationen till funktionsbeskrivningen har kompilerats från tillverkarmanualer, konstruktionsritningar, informationspärmar, intervjuer samt ABB styrsystem. Bilder har tagits och redigerats, för att ge en illustrativ överblick av fluider och gasers väg genom gassystemet och dess kringutrustning. Information och bilder har sedan sammanställts i en funktionsbeskrivning (Se bilaga 1).The study which is presented in this report has been carried out at R1K, which is a section of the Rönnskär smelter plant. The plant is owned by New Boliden. In the year of 2007 a new gas system containing several new components were built. The operators that were in charge of monitoring the new system were not given sufficient education about the new components and their part in the system as whole. The purpose of this study is to create a function functional description about the system and all its components. The functional description is to be presented in the form of an easy-to-use manual for both experienced and new operators. The manual has been compiled from manufacturer manuals, construction blueprints, scattered operator manuals, knowledge of the ABB operator-system and interviews with various employees. To give the operators and the readers a good visual overview of all the different gas and fluid flows in the system pictures have been taken. All this have been compiled into the operator manual that is the functional description. (See attachment 1)
