Organization and structure of the cardiothoracic intensive care unit

The purpose of this chapter is to emphasize and describe the team nature of critical care medicine in the Cardiothoracic Intensive Care Unit. The chapter will review the importance of various team members and discuss various staffing models (open vs closed, high intensity vs low intensity, etc.) on patient outcomes and cost. The chapter will also examine the roles of nurse practitioners and physician assistants (NP/PAs) in critical care, and will briefly review the growing role of the tele-ICU. Most studies support the concept that a multi-disciplinary ICU team, led by an intensivist, improves patient outcomes and decreases overall cost of care. The role of the tele-ICU and 24 hour in-house intensivist staffing in improving outcomes is controversial, and more research is needed in this area. Finally, a brief discussion of billing for critical care will be discussed.

The Design of Hypermedia Tools for Learning: Fostering Conceptual Change and Transfer of Complex Scientific Knowledge

A central premise of this article is that hypermedia tools may be developed for case and problem-centered learning in order to achieve significant learning outcomes such as deep conceptual understanding, conceptual change, and knowledge transfer. An approach for developing hypermedia case and problem-centered knowledge resources is proposed-the knowledge mediator framework (KMF)-which consists of design elements and learning activities that have specific sociocognitive theoretical and research rationales. A proof-of-concept study is then discussed; it involved high school students using a hypermedia system based on the main features of the KMF to learn neo-Darwinian evolutionary biology. Students using the experimental hypermedia system were found to change their evolutionary biology problem-solving models, and to continue to use expert-like models even 1 year after using the system. The use of the KMF to develop hypermedia learning materials in other domains and for constructive student projects is also considered. Overall, it is hoped that the framework and research outlined in this article may contribute to design and pedagogical principles for hypermedia learning tools that help students construct rich and useful understandings of challenging knowledge.
Neural-network-aided design for image processing

A new concept of Neural Network-Aided Design (NN-AD) is presented. It is a hierarchical approach consisting of several concatenated stages of visual information processing that are designed by training neural networks (NN). Thus, NN-AD can be viewed as a general tool for the design of special filters in accordance with the specific task of image processing under consideration. The nonlinear filters are formatted by a supervised presentation of a proper set of input-output patterns. The principles of NN-AD design are illustrated by the examples of edge detection with subpixel resolution and of orientational processing for edge enhancement. The proposed NN-AD approach is found to be very robust with regard to various types of errors.
An academic data warehouse

There are several benefits that can be reached by developing an academic data warehouse as providing a centralized source of information accessible across different academic units to quickly analyze problems and get satisfactory solutions, supplying the data necessary for developing the Institution's strategic plan, and enabling administrator to make better business decisions based on historical data available in legacy databases. The paper describes the architecture of an academic data warehouse. Examples of analytic reporting are also reported.
The Pooling Principle

A key insight of basic inventory models and of the G/G/m queueing model is the effect of “pooling. ” That is, these models suggest that pooling of customer demands, along with pooling of the resources used to fill those demands, may yield operational improvements. While there are many research papers that articulate and quantify the benefits of pooling, a review of popular texts in operations management suggests that most texts lack simple examples that illustrate this important concept. This note is intended to fill this void by articulating the “pooling principle” in an intuitive, straightforward fashion. This note is comprised of a brief instructor's note, followed by a note that can be included in a course pack or handed out to students. Earlier versions of the note have been used successfully in core operations courses at both the undergraduate business and MBA levels.
Dual factor routing protocol for mobile ad hoc networks

Mobile ad hoc networking works properly only if the participating nodes cooperate in routing and forwarding. In this work, the question of how to enable a system to operate despite the presence of misbehavior node is considered. Node misbehavior due to selfish or malicious reasons or faulty nodes can significantly degrade the performance of mobile ad hoc networks. A new protocol called DUAL Factor is proposed to manage with misbehavior nodes. It considers two factors, Direct Factor and Distributed Factor, called DUAL Factor. The DUAL Factor protocol works as an extension to a reactive source-routing protocol for mobile ad-hoc networks. The performance analysis of DUAL Factor is done by comparing it to the standard DSR protocol. It shows that a network with DUAL Factor and up to 60% of misbehaving nodes behaves almost same as a caring network, in sharp contrast to a standard DSR network. All simulations have been implemented and performed in ASIM Simulator.
Speech enhancement for mobile telephony

The properties of noise fields in automobile interiors are discussed with a view toward speech enhancement for voice-activated mobile telephony. The limitations on performance of adaptive noise cancellation are explained in the context of the spatial correlation properties of the noise field. A simple delay-equalized near-field array of directional microphones is analyzed and found to be effective for increasing the signal-to-noise density ratio (SNR) and reducing the reverberant distortion of the speech, without introducing any further distortion. An array of N microphones, each with a delay and weight chosen according to its distance from the speech source, is a viable solution. Such an array gives gains on the order of N over the speech band, reduces reverberation, and does not introduce waveform distortion. Experimental results confirming the predicted performance are presented. >
Beyond Introductory Programming: Success Factors for Advanced Programming.

Numerous studies document high drop-out and failure rates for students in computer programming classes. Studies show that even when some students pass programming classes, they still do not know how to program. Many factors have been considered to explain this problem including gender, age, prior programming experience, major, math background, personal attributes, and the programming language itself. Research in this area has mainly been confined to introductory programming courses. This study explores the problem at a higher level. It tracks students longitudinally as they move from the first introductory programming class, to the second introductory class, and finally, to completion of an advanced programming course. The research question answered was: What are the factors contributing to the success or lack of success in advanced programming? The success factors examined were the introductory programming language taken, number of programming classes taken, track (concentration in the major), math and logic background, time lapse between the introductory and advanced programming class, instructor, gender, and general GPA. The factors that influenced student success were found to be the introductory programming language, time lapse between the introductory and advanced class, general grade point average, and track. Identification of these factors will help educators to make the best decisions on how to improve computer curriculum and programs and help students become better programmers.

Neue Testverfahren in der Präventionsstrategie des kolorektalen Karzinoms

Zusammenfassung Zu den neuen Verfahren beim Darmkrebs-Screening zählen die immunologischen Stuhlbluttests (iFOBT), DNA-Stuhltests, Blut-/ und Serummarker sowie darüber hinaus visualisierende Verfahren wie CT-/MRT, Kolon-Kapsel und Oncoscope. Aktuell haben die immunologischen Stuhltests die besten Karten, nach Festlegung von standardisierten Qualitätskriterien in das Früherkennungsprogramm der gesetzlichen Krankenversicherung aufgenommen zu werden. Molekulare Blut- und Serummarker sind noch in der Evaluationsphase. Ihre Bestimmung und ihr Preis sind aktuell noch ein Hindernis für ein Massen-Screening. Die CT-Kolonographie hat exzellente Detektionsraten, scheidet in Deutschland aber wegen der Strahlenbelastung als Screening-Verfahren derzeit aus. Die MR-Kolonographie kommt ohne Strahlen aus, steckt aber noch in der Entwicklungsphase. Die Kolon-Kapsel hat möglicherweise das Potenzial, ein guter diagnostischer Filter zu werden. Durch diese neuen Entwicklungen lassen sich die Teilnahmeraten beim Screening wahrscheinlich nur marginal steigern. Somit sind zukünftig auch politische Strategien zu fordern, das derzeit vorliegende opportunistische Screening umzustellen.
AN INVESTIGATIVE SCHEME FOR KEYWORD SEARCH USING INVERTED KEY TACTIC

Unverified classification of outlines that is data items, observations or feature vectors into groups is called as Clustering. To retrieve a document from a group of documents according to a set of keywords efficiently, Inverted lists are mostly used instead of Keyword Search. Keyword Search is one of the most important activities in Information Retrieval System. As study shows in latest years, Keyword search is widely used by users to access text data. Keyword search is appropriate for document gatherings as well as for accessing structured or semi-structured data, XML documents relational databases and relational tables which can also be regarded as sets of documents. This is done by a keyword as query user retrieve documents. To proficiently retrieve documents, a data structure is used, that maps each word in the dataset, to a list of IDs of documents in which the word appears. The inverted index for a document collection consists of a set of so-called inverted lists, known as posting lists.
Evaluation of Concurrent Thinking Aloud Using Eye-tracking Data

In a series of studies we addressed the two questions of: 1) Do verbalizations reflect concurrent thought, and 2) Does concurrent thinking aloud differ from normal thinking? The design of experimental tests was based upon Ericsson and Simon's model of thinking aloud, incorporating variations of how information is represented in short term memory. Eye-movement recordings were used as a source of additional data, allowing us to go beyond a mere analysis of solution time and accuracy. Comparing verbalizations and eye-movement data, we arrived at a positive answer to the first of our initial questions. The second question was approached on several levels, always involving a comparison of ‘think-aloud groups’ with silent controls. We found no differences with respect to accuracy, but longer solution times in think-aloud groups. In a final experiment, the influence of thinking aloud on concurrent task performance could be narrowed down to an effect which only persists through the early stages of familiarization with tasks. We conclude that concurrent verbalization is a viable tool in the study of cognitive processes.

Designing a Moodle course with the CADMOS learning design tool

CADMOS is a graphical learning design (LD) authoring tool that helps a teacher design a unit of learning in two layers: (i) the conceptual layer, which seems like a concept map and contains the learning activities with their associated learning resources and (ii) the flow layer, which contains the orchestration of these activities. One of CADMOS’ main innovative features is that it can bridge the gap between the design of a unit of learning and its enactment into Moodle. This paper presents how one can create a LD using CADMOS and deploy it into Moodle. Also, the paper shows the findings from a case study which was organized in order to evaluate the usability of the tool, its pedagogical flexibility and the usefulness of its innovative feature of deploying a LD into Moodle. CADMOS seems to be an easy-to-use tool, which offers guidance and flexibility during the design process.
UAV Path Following for Constant Line-of-Sight

This work provides algorithms for flight path guidance and synchronous camera angles to observe a target. The observation of the target is affected by the environment, maximum aircraft performance, and camera limits. Analytic expressions are derived for trajectories required for constant line-of-sight orientation relative to the aircraft. A guidance law based on ‘good helmsman’ behavior is implemented. An observer is used to estimate wind data, which is used to orient the trajectories about the target. Results are demonstrated in simulated maneuvers with exposure to variable wind and turbulence.
Comparison of formant detection methods used in speech processing applications

The paper describes time frequency representations of speech signal together with the formant significance in speech processing applications. Speech formants can be used in emotion recognition, sex discrimination or diagnosing different neurological diseases. Taking into account the various applications of formant detection in speech signal, two methods for detecting formants are presented. First, the poles resulted after a complex analysis of LPC coefficients are used for formants detection. The second approach uses the Kalman filter for formant prediction along the speech signal. Results are presented for both approaches on real life speech spectrograms. A comparison regarding the features of the proposed methods is also performed, in order to establish which method is more suitable in case of different speech processing applications.

Prise en charge des accidents vasculaires cérébraux en France métropolitaine. Résultats de 3 enquêtes nationales

Ce travail presente les resultats de trois enquetes sur les accidents vasculaires cerebraux menees en France en mars 1999. Trois cent quarante-cinq services d'Urgences, 93 services de Neurologie et 258 services de Reeducation-Readaptation Fonctionnelle ont repondu a ces enquetes. Cinquante pour cent des patients souffrant d'AVC franchissent le seuil des urgences dans les 3 heures suivant la constitution de leur deficit. Mais seulement 40 p. 100 sont admis dans un service de Neurologie et 5 p. 100 dans une Unite de Soins Intensifs NeuroVasculaires. Les durees moyennes de sejour hospitalier (phase aigue) peuvent etre tres longues, superieures a 3 semaines, du fait des delais d'admission dans les services de soins de suite. Cette etude montre que la prise en charge des AVC est extremement heterogene et peu structuree en France.
Agent-Based Learning Environments as a Research Tool for Investigating Teaching and Learning

By using intelligent agents to simulate instruction, agent-based learning environments can serve as a powerful research tool to investigate teaching and learning. The agent metaphor provides a way to operationalize and simulate the “human” aspect of instruction in a more ecologically valid way than other controlled computer-based methods. Additionally, from an architectural perspective, since agents are independent objects in the learning environment, it allows for more flexibility in research design. In particular, agent-based learning environments with multiple agents, such as MIMIC (Multiple Intelligent Mentors Instructing Collaboratively), allow for investigating the effect of multiple mentors or multiple perspectives on a learning topic. Preliminary results from MIMIC research indicate that multiple agents can serve to effectively operationalize instructional theory. In terms of overall impact, creating agent-based learning environments to investigate instructional issues is at the leading edge of revitalized research integrating artificial intelligence with education, and in exploring new paradigms for researching teaching and learning.
A Study on System Virtualization Techniques

Taking something in one form and presenting into another form is referred as virtualization. The concept of virtualization is very broad and is applied to devices, machine stack, files, networks and storage systems.However,system virtualization’s ability for reducing and optimizing resource consumption towards sustainable computing, provides a mechanism to consolidated application along with existing OS,middleware,and communication environment on a single shared systems makes it hot topic in industry.Hence,this paper gives brief overview of x86 virtualization techniques that provides a high level description about virtualization including the concept of a virtual machine monitor(VMM), virtualization properties, and its applications. Further it contrast different form of x86 system level virtualization and suggests when and where a desirable technology is appropriate. And finally it concludes with a notion possible new directions that would be faced during the implementation of VMM and hardware architecture, to make them widely accepted.
Gelenkerhalt bei Frühinfektion nach Hüfttotalendoprothese

Zusammenfassung Hintergrund: Die periprothetische Infektionsrate nach Hüfttotalendoprothese (HTEP) liegt ohne patientenspezifische Risikofaktoren bei ca. 1 %. Die therapeutischen Herausforderungen bestehen im Beherrschen der Infektion, in der Wiederherstellung der funktionellen Belastbarkeit des Hüftgelenks und der Vermeidung einer Re-Infektion. Bei Frühinfektion und akuter hämatogener Infektion stellt das Therapieregime des Débridements mit Spülung und Austausch der mobilen Komponenten unter Erhalt der Prothese eine wertvolle Alternative zum ein- oder zweizeitigen Wechsel dar. In aktuellen Studien wurden hierzu neue Therapiealgorithmen vorgestellt. Patienten und Methoden: Es wird eine Übersicht über aktuelle Therapiekonzepte gegeben. Vorgestellt werden zudem die Ergebnisse einer retrospektiven Studie von 73 Patienten, die zwischen 2002 und 2011 in der eigenen Klinik aufgrund einer Frühinfektion oder einer akuten hämatogenen Infektion nach HTEP mit Débridement und Spülung unter Erhalt der Prothese und Austausch der mobilen Teile behandelt wurden. Ergebnisse: Aktuelle Literaturergebnisse zeigen, dass die Therapiestrategie des Débridements mit Spülung und Austausch der mobilen Teile unter Prothesenerhalt nur bei Frühinfektionen innerhalb eines Zeitraums von maximal 4 Wochen nach der Indexoperation oder bei hämatogenen Infektionen mit einer Symptomdauer von maximal 3 Wochen erfolgversprechend ist. In unserer retrospektiven Studie mit 73 Patienten war dieses Konzept bei 46 Patienten (63 %) erfolgreich (Infektionsfreiheit). Eine persistierende Infektion nach Débridement und Spülung wurde bei 27 Patienten (37 %) detektiert. In 28,8 % der Infektionen lagen „Difficult-to-treat“-Erreger vor. Schlussfolgerung: Das Konzept von Débridement und Spülung mit Erhalt der Prothese und Austausch aller mobilen Teile kann bei Patienten mit Frühinfektion oder akuter hämatogener Infektion eine sinnvolle Alternative zum ein- oder zweizeitigen Wechsel darstellen. Eine maximale Symptomdauer von 3 Wochen bei hämatogenem Infekt bzw. eine maximale Zeitspanne von 4 Wochen nach der Indexoperation bei der Frühinfektion muss unbedingt beachtet werden. Die Erfolgsraten des Gelenkerhalts sind geringer als bei zweizeitigem Vorgehen. Obligatorische Voraussetzungen für den Versuch des Prothesenerhalts mittels Débridement und Spülung sowie Austausch der mobilen Teile sind der stabile Prothesensitz, adäquate Weichteile und ein antibiotikasensibler Keim.
