    Hu, Amanda; Shewokis, Patricia A; Ting, Kimberly; Fung, Kevin

    2016-08-01

    Computer-aided instruction (CAI) is defined as instruction in which computers play a central role as the means of information delivery and direct interaction with learners. Computer-aided instruction has become mainstream in medical school curricula. For example, a three-dimensional (3D) computer module of the larynx has been created to teach laryngeal anatomy. Although the novelty and educational potential of CAI has garnered much attention, these new technologies have been plagued with low utilization rates. Several experts attribute this problem to lack of motivation in students. Motivation is defined as the desire and action toward goal-oriented behavior. Psychologist Dr. John Keller developed the ARCS theory of motivational learning, which proposed four components: attention (A), relevance (R), concentration (C), and satisfaction (S). Keller believed that motivation is not only an innate characteristic of the pupil; it can also be influenced by external factors, such as the instructional design of the curriculum. Thus, understanding motivation is an important step to designing CAI appropriately. Keller also developed a 36-item validated instrument called the Instructional Materials Motivation Survey (IMMS) to measure motivation. The objective of this study was to study motivation in CAI. Medical students learning anatomy with the 3D computer module will have higher laryngeal anatomy test scores and higher IMMS motivation scores. Higher anatomy test scores will be positively associated with higher IMMS scores. Prospective, randomized, controlled trial. After obtaining institutional review board approval, 100 medical students (mean age 25.5 ± 2.5, 49% male) were randomized to either the 3D computer module (n = 49) or written text (n = 51). Information content was identical in both arms. Students were given 30 minutes to study laryngeal anatomy and then completed the laryngeal anatomy test and IMMS. Students were categorized as either junior (year 1

  12. Interactive computer-assisted instruction in acid-base physiology for mobile computer platforms.

    Science.gov (United States)

    Longmuir, Kenneth J

    2014-03-01

    In this project, the traditional lecture hall presentation of acid-base physiology in the first-year medical school curriculum was replaced by interactive, computer-assisted instruction designed primarily for the iPad and other mobile computer platforms. Three learning modules were developed, each with ∼20 screens of information, on the subjects of the CO2-bicarbonate buffer system, other body buffer systems, and acid-base disorders. Five clinical case modules were also developed. For the learning modules, the interactive, active learning activities were primarily step-by-step learner control of explanations of complex physiological concepts, usually presented graphically. For the clinical cases, the active learning activities were primarily question-and-answer exercises that related clinical findings to the relevant basic science concepts. The student response was remarkably positive, with the interactive, active learning aspect of the instruction cited as the most important feature. Also, students cited the self-paced instruction, extensive use of interactive graphics, and side-by-side presentation of text and graphics as positive features. Most students reported that it took less time to study the subject matter with this online instruction compared with subject matter presented in the lecture hall. However, the approach to learning was highly examination driven, with most students delaying the study of the subject matter until a few days before the scheduled examination. Wider implementation of active learning computer-assisted instruction will require that instructors present subject matter interactively, that students fully embrace the responsibilities of independent learning, and that institutional administrations measure instructional effort by criteria other than scheduled hours of instruction.

    Because of successive formation of large accidents such as critical accident in JCO, exfoliation of concrete in JR, some opinions were increased on anxiety of decline on technical capacity in Japan. Required for a long term from its construction to its operation, a nuclear power plant is now at a state difficult to practise its technical tradition at its working field. In order to hand down technique with good quality, it is essential to receive a wrong experience such as trouble as a noble inheritance, to exert without losing it by its forgetting. The Wakasa Branch of the Kansai Electric Power Co., Ltd. has exerted renewal of its instruments and so on laid stress on their reliability and safety by activating its nuclear technical capacity and some instructions on past trouble. The Branch edited these informations and experiences to a data of CD ROM aiming at smooth technical tradition for next generation. Process on transition of the nuclear technical capacity is laid from beginning of nuclear power plant to APWR. By using the data, four technical instructions on volume of the central control board, volume of reactor vessel (R/V), volume of steam generator (S/G), and volume of RCP have been already made-up. Here were introduced on volumes of R/V and S/G belonging to their mechanical systems. (G.K.)

  17. Revisiting cognitive and learning styles in computer-assisted instruction: not so useful after all.

    Science.gov (United States)

    Cook, David A

    2012-06-01

    In a previous systematic review, the author proposed that adaptation to learners' cognitive and learning styles (CLSs) could improve the efficiency of computer-assisted instruction (CAI). In the present article, he questions that proposition, arguing that CLSs do not make a substantive difference in CAI. To support this argument, the author performed an updated systematic literature search, pooled new findings with those from the previous review, and reinterpreted this evidence with a focus on aptitude-treatment interactions. (An aptitude-treatment interaction occurs when a student with attribute 1 learns better with instructional approach A than with approach B, whereas a student with attribute 2 learns better with instructional approach B).Of 65 analyses reported in 48 studies, only 9 analyses (14%) showed significant interactions between CLS and instructional approach. It seems that aptitude-treatment interactions with CLSs are at best infrequent and small in magnitude. There are several possible explanations for this lack of effect. First, the influence of strong instructional methods likely dominates the impact of CLSs. Second, current methods for assessing CLSs lack validity evidence and are inadequate to accurately characterize the individual learner. Third, theories are vague, and empiric evidence is virtually nonexistent to guide the planning of style-targeted instructional designs. Adaptation to learners' CLSs thus seems unlikely to enhance CAI. The author recommends that educators focus on employing strong instructional methods. Educators might also consider assessing and adapting to learners' prior knowledge or allowing learners to select among alternate instructional approaches.

    Smith, Bethany

    The need for promoting scientific literacy for all students has been the focus of recent education reform resulting in the rise of the Science Technology, Engineering, and Mathematics movement. For students with Autism Spectrum Disorders and intellectual disability, this need for scientific literacy is further complicated by the need for individualized instruction that is often required to teach new skills, especially when those skills are academic in nature. In order to address this need for specialized instruction, as well as scientific literacy, this study investigated the effects of embedded computer-assisted instruction to teach science terms and application of those terms to three middle school students with autism and intellectual disability. This study was implemented within an inclusive science classroom setting. A multiple probe across participants research design was used to examine the effectiveness of the intervention. Results of this study showed a functional relationship between the number of correct responses made during probe sessions and introduction of the intervention. Additionally, all three participants maintained the acquired science terms and applications over time and generalized these skills across materials and settings. The findings of this study suggest several implications for practice within inclusive settings and provide suggestions for future research investigating the effectiveness of computer-assisted instruction to teach academic skills to students with Autism Spectrum Disorders and intellectual disability.

    Yalçinalp, Serpil; Geban, Ömer; Özkan, Ilker

    This study examined the effect of computer-assisted instruction (CAI), used as a problem-solving supplement to classroom instruction, on students' understanding of chemical formulas and mole concept, their attitudes toward chemistry subjects, and CAI. The objective was to assess the effectiveness of CAI over recitation hours when both teaching methods were used as a supplement to the traditional chemistry instruction. We randomly selected two classes in a secondary school. Each teaching strategy was randomly assigned to one class. The experimental group received supplementary instruction delivered via CAI, while the control group received similar instruction through recitation hours. The data were analyzed using two-way analysis of variance and t-test. It was found that the students who used the CAI accompanied with lectures scored significantly higher than those who attended recitation hours, in terms of school subject achievement in chemistry and attitudes toward chemistry subjects. In addition, there was a significant improvement in the attitudes of students in the experimental group toward the use of computers in a chemistry course. There was no significant difference between the performances of females versus males in each treatment group.Received: 26 April 1994; Revised: 6 April 1995;

    The purpose of this study was to compare the performance of students exposed to two different instructional modalities for dental anatomy wax carving: CAI (computer-assisted instruction) using DVD technology, or traditional laboratory instruction. Students' self-assessment scores were also compared to faculty scores, and students' perceptions of their teaching modality were analyzed. Seventy-three first-year dental students (response rate 81 percent) participated in this randomized single blind trial, in which faculty graders were blinded to student group assignment. There were no statistical differences, as determined by the Wilcoxon non-parametric test and a t-test, between the faculty grades on the wax carving from the two teaching methods the students experienced. The student self-assessments revealed higher mean grades (3.0 for the DVD-only group and 3.1 for the traditional group) than the faculty actual mean grades (2.2 for both the DVD-only group and the traditional group) by almost one grade level on a 4.0 grade scale. Similar percentages of students in the traditional group had either favorable or unfavorable perceptions of their learning experience, while more students in the DVD-only group reported favorable perceptions. Students from both groups said they wanted more faculty feedback in the course. Based on these objective and subjective data, merging CAI and traditional laboratory teaching may best enhance student learning needs.

    Full Text Available Computer technology has become an integral part of physical education, yet there have been few studies exploring the use of multimedia technology in the instruction of Physical Education. The purpose of this study was to investigate if multimedia technology affected the learning of basic ballet skills. A total of 32 female students, mean age 18.1 years, studying at the Faculty of Physical Education Zagazig university were divided into two groups. The experimental group comprised 16 students. Participants in this group participated in a ballet class with multimedia technology for six weeks. Group two participated in the ballet class with the traditional method as the control group. Parameters assessed height, weight, age, and academic level. All participants were free of any disorders known to affect performance, such as bone fractures, osteoporosis, diabetes, or cardiovascular disease. Participants reported no use of anti-seizure drugs or alcohol. In addition, all participants were fully informed of the aims of the study, and gave their voluntary consent prior to participation. The measurement procedures were in accordance with ethical human experimentation. All statistical analyses were calculated with the SPSS statistical package. Results indicated significant differences between the two groups in learning the basic skills and levels of knowledge of ballet. Applying the proposed educational program meant using multimedia to teach basic ballet skills to second-year female students enrolled in the Faculty of Physical Education

  4. The impact of instructional design in a case-based, computer-assisted instruction module on learning liver pathology in a medical school pathology course

    Science.gov (United States)

    Latham, Patricia S.

    The purpose of this quantitative experimental study was to test the impact of three learning interventions on student learning and satisfaction when the interventions were embedded in the instructional design of case-based, Computer-Assisted Instruction (CAI) modules for learning liver pathology in an in-class, self-study, laboratory exercise during a Year-2 medical school Pathology course. The hypothesis was that inclusion of the learning interventions would enhance student satisfaction in using the CAI and improve subsequent CAI-directed exam performance. Three learning interventions were studied, including the use of microscopic virtual slides instead of only static images, the use of interactive image annotations instead of only still annotations, and the use of guiding questions before presenting new information. Students were randomly assigned to with one of eight CAI learning modules configured to control for each of the three learning interventions. Effectiveness of the CAI for student learning was assessed by student performance on questions included in subsequent CAI-directed exams in a pretest and on posttests immediately after the lab exercise, at two weeks and two months. Student satisfaction and perceived learning was assessed by a student survey. Results showed that the learning interventions did not improve subsequent student exam performance, although satisfaction and perceived learning with use of the CAI learning modules was enhanced. Student class rank was evaluated to determine if the learning interventions might have a differential effect based on class rank, but there were no significant differences. Class rank at the time of the lab exercise was itself the strongest predictor of exam performance. The findings suggest that the addition of virtual slides, interactive annotations and guiding questions as learning interventions in self-study, case-based CAI for learning liver pathology in a medical class room setting are not likely to increase

    Full Text Available This study examined the effects that computer-assisted instruction had on students’ attitudes toward a mathematics lesson and toward learning mathematics with computer-assisted instruction. The computer software we used was based on the ASSURE Instructional Systems Design and the ARCS Model of Motivation, and the software was designed to teach fractions to fourth-grade students. The skill levels of these students were gauged before and after receiving the computer-assisted instruction. We structured our experimental design to use one group for both pre- and post-tests, which is considered to be one of the weak experimental designs. We conducted our research with 28 students studying in Balıkesir, Turkey, for a period of six weeks, using the specifically developed teaching material. We gathered our research data by applying an attitude scale to our mathematics lesson and to computer-assisted instruction. We also applied the Academic Achievement Test for Fractions Unit in Mathematics, a test we developed for our research. We analyzed our gathered data with the Wilcoxon Signed-Rank Test (n0.05. Based on the research results, we believe that similar materials can also be used for instructing other topics of mathematics, and similar computer-assisted activities can be developed for other courses.

    The Student Training, Education and Practice for Dietetics (STEP-DIET) CD-ROM was developed at the University of Surrey to prepare dietetic students for the practical dietetic training component of their Nutrition/Dietetics degree. This study aimed to evaluate student response to the programme and its effectiveness as a teaching tool, based on the evaluation framework of D.L. Kirkpatrick (Evaluating a Course, 2nd edn. London, Kogan Page). Quantitative and qualitative methodologies were employed, with 41 dietetic students, separated by year group, completing questionnaires and taking part in six focus groups, at the University of Surrey. Student attitudes towards the instruction method and the STEP-DIET programme itself were investigated, in conjunction with their perceived learning achievements. Students rated the programme highly in terms of design and content, however, there was a reluctance to accept computer-assisted instruction (CAI) as a sole teaching method. A number of learning achievements relevant to dietetic practice were reported including a perceived increase in ability to conduct a dietetic interview and an increased understanding of the management of Type 2 diabetes. In general students reacted positively to the STEP-DIET programme and it was perceived by students to be effective in preparing them for the practical component of their dietetic training.

In the encirclement of more and more intensive use of computer techniques that help to CAAT all the aims and the volume of auditing do not change when the audit is done in the computer-informatics environment. The computer assisted audit technique (CAATs can improve the efficiency and productivity of audit procedures. In the computerized information system, the CAATs are the ways in which an auditor can use computer to gather or as help in gathering auditing evidence. There are more reasons why the auditors apply computer techniques that help in auditing. Most often, they do it to achieve improvement of auditing efficiency when the data volume is large. It depends on several factors whether the auditors will apply the computer techniques that help auditing and to what degree respectively. If they do it, the most important are the computer knowledge, professional skill, experience of auditors, and availability of computer technique, and adequacy of computer supports, infeasibility of hand tests, efficiency and time limit. Through several examples from practice, we showed the possibilities of ACL as one of the CAAT tools.

    Spinal computed tomography was carried out after intrathecal introduction of metrizamide. This technique can clearly visualize the spinal subarachnoid space and structures contained in this space, and is an accurate and satisfactory modality for detecting spinal cord and various spinal lesions. In the cases with syringomyelia, the reflux of metrizamide into the syrinx was most marked several hours following intrathecal introduction of metrizamide. Computer assisted myelography with metrizamide is essential in the diagnosis of communicating sylingomyelia. It will demonstrate intraspinal extention and the total geography of the spinal cord tumor. Authors present their technique and results with representative cases of various spinal lesions.

    This study examined the extent to which a computer-based social skills intervention called FaceSay was associated with improvements in affect recognition, mentalizing, and social skills of school-aged children with Autism Spectrum Disorder (ASD). FaceSay offers students simulated practice with eye gaze, joint attention, and facial recognition skills. This randomized control trial included school-aged children meeting educational criteria for autism (N = 31). Results demonstrated that participants who received the intervention improved their affect recognition and mentalizing skills, as well as their social skills. These findings suggest that, by targeting face-processing skills, computer-based interventions may produce changes in broader cognitive and social-skills domains in a cost- and time-efficient manner.

    2004-07-01

    This paper discusses the relevance of digital computation in Fuels and Combustion Laboratory experiments used by the senior students of the Department of Mechanical Engineering, De La Salle University-Manila, Philippines. One of the students' experiments involved the determination of the most efficient CDOM fuel proportion as alternative fuel to diesel oil for steam generators and other industrial applications. Theoretical calculations show that it requires tedious and repetitive computations. A computer-assisted program was developed to lessen the time-consuming activities. The formulation of algorithms were based on the system of equations of the heat interaction between the CDOM fuel, combustion air and products of combustion and by applying the principles of mass and energy equations (or the First Law of Thermodynamics) for reacting systems were utilized. The developed computer-assisted program output verified alternative fuel selected through actual experimentation.

In the environment of education informationization, it is very necessary and feasible to use computer-aided instruction in special education. Because computers are multimedia, integrated and interactive, they can not only help the special students do rehabilitation training, but also help them learn better. But when computer-aided instruction is applied to the field of special education, it has such defects as less hardware and software resources, poor quality, uneven development and the unitary application model and can not play its due role. In order to carry out computer-aided instruction better, we should change concepts, integrate human and financial resources at colleges, universities and special education schools and exert ourselves together to develop and use various resources.

    Weisman, Melanie

    1988-02-01

    As newer and more sophisticated imagery collection systems rapidly increase the volume of imagery requiring thorough exploitation, the need for imagery analysts to acquire and maintain expertise increases accordingly. In response, Loral Systems Group (Arizona) has produced a computer-based-training (CBT) system that presents a series of lessons on radar imaging principles and their application to the various orders of battle. The training system is composed of two host computers, four student/instructor workstations, a printer, and lesson material. The computers control the imagery presentation, deliver twenty-eight interactive lessons of computer-assisted instruction, and generate reports. Each dual-screen workstation presents lessons consisting of instructional text coupled with representative imagery annotated with color graphics. Although the system is designed for the unique characteristics of radar interpretation, alternative courseware could instruct interpretation techniques for other imagery (photographic, electro-optical, infrared). Regardless of the sensor type and amount of available imagery, both commercial and military segments of the interpretation community will benefit only if the interpreter/analyst is successfully trained to translate image information into useful terms.

    radiologists using the computer based image browser demonstrated significant differences in how the experts, novices and intermediates interact with the image archive via the overview plot. These findings are consistent with those found in previous novice-expert studies involving chest x-ray interpretation. There were significant differences between the experts and novice/intermediates in terms of their placement of cases within the overview plot with the experts placement of cases closer to the statistical placements. The users reaction to the overview plot were favourable with subjects commenting on its intuitiveness and ease of use. Hence, it is concluded that the overview space could serve as a useful tool in assisting the training of novice and intermediate radiologists providing a vehicle for moving the less experienced subjects towards the experts' conception of a disease. The research offers a methodology for teaching based on the integration of principles from cognitive science and statistics, and as...

    The computer-based tutoring of visual concepts such as radiological images is a largely unexplored area. A review of the literature highlights limited use of computers as a means of radiological education, with the majority of systems being little more than hypermedia prototypes, on-line teaching files, and passive CD-Roms. Very few of the systems discussed in the research literature draw on the work from cognitive science and educational psychology for tutoring visual concepts. This thesis details and evaluates a method for indexing and retrieving images from large image databases via a cognitively informed graphical representation of visual concepts. This representation is derived using Multiple Correspondence Analysis from a statistical analysis of features present in the images. It is intended that this representation be used to assist in the computer based teaching of any discipline that requires the tutoring of visual concepts. The domain used as a test bed for this research is Magnetic Resonance Imaging in neuroradiology. Tutoring the interpretation of MR scans of the head represents a real practical problem due to the inherent complexity of the brain and variations in tissue contrast within image sequence and disease/pathology. The literature of concept categorisation and representation is critically reviewed to inform the design of a graphical representation of a concept (a pathology in the application domain). A specification for the design of an explicit representation of visual concepts is drawn from this literature review, together with methods of tutoring based around this model. A methodology for producing this representation is described, and implemented in the development of an overview plot for the concept of a disease of the brain, with associated statistical measures derived and operationalised for typicality and similarity of cases within a disease. These measures are precursors to the development of computer based tutoring strategies for image

    Slipped capital femoral epiphysis (SCFE) is a common pediatric orthopedic disorder that requires surgical correction. Preoperative planning of a proximal femoral osteotomy is essential in cases of SCFE. This planning is usually done using 2D radiographs, but 3D data can be acquired with CT and analyzed with 3D visualization software. SCFEanalyzer is a computer program developed for preoperative planning of proximal femoral osteotomy to correct SCFE. Computed tomography scans were performed on human bone specimens: one pelvis and two femoral bones (right and left) and volume data of a patient. The CT data were used to test the abilities of the SCFEanalyzer software, which utilizes 3D virtual models of anatomic structures constructed from CT image data. Separation of anatomical bone structures is done by means of ''cutting'' 3D surface model of the pelvis. The software enables qualitative and quantitative spatial analysis of chosen parameters analogous to those done on the basis of plain radiographs. SCFEanalyzer makes it possible to evaluate the function of the hip joint by calculating the range of motion depending on the shape of bone structures based on oriented bounding box object representation. Pelvic and hip CT scans from a patient with SCFE were subjected to femoral geometry analysis and hip joint function assessment. These were done to plan and simulate osteotomy of the proximal femur. Analogous qualitative and quantitative evaluation after performing the virtual surgery were evaluated to determine the potential treatment effects. The use of computer assistance in preoperative planning enable us to increase objectivity and repeatability, and to compare the results of different types of osteotomy on the proximal femur, and thus to choose the optimal operation in each individual case.

    Multiple instruction rollback (MIR) is a technique that has been implemented in mainframe computers to provide rapid recovery from transient processor failures. Hardware-based MIR designs eliminate rollback data hazards by providing data redundancy implemented in hardware. Compiler-based MIR designs have also been developed which remove rollback data hazards directly with data-flow transformations. This paper describes compiler-assisted techniques to achieve multiple instruction rollback recovery. We observe that some data hazards resulting from instruction rollback can be resolved efficiently by providing an operand read buffer while others are resolved more efficiently with compiler transformations. The compiler-assisted scheme presented consists of hardware that is less complex than shadow files, history files, history buffers, or delayed write buffers, while experimental evaluation indicates performance improvement over compiler-based schemes.

    Full Text Available This study applied multimedia in a general engineering and technology course in Taiwan and evaluated the effectiveness of multimedia-assisted instruction and learning. The course presented trends in technological development and the achievements of Taiwanese industries and research institutes from a historical perspective, and overviewed the technology industries and industrial transformation development in Taiwan. The course units adopted multimedia to support class teaching and student learning, and a survey was conducted to collect students’ attitudes and perception toward multimedia-assisted instruction and learning in the course. Research data were collected from 45 male and 9 female students with varied academic and cultural backgrounds. Results showed that multimedia videos help raise students’ awareness of learning issues, improve their understanding of content, and increase the depth of their learning. Almost all students liked the approach of using multimedia to assist teaching and learning, preferring this approach over traditional lecture-based instruction. They also would recommend this course to their peers. This study also found that the degree of students’ engagement caused variance in the students’ perception of multimedia helpfulness in assisting their learning. Finally, this study further proposes suggestions in both design and research on applications of multimedia-enhanced learning in engineering and technology education.

    Multiple instruction rollback (MIR) is a technique to provide rapid recovery from transient processor failures and was implemented in hardware by researchers and slow in mainframe computers. Hardware-based MIR designs eliminate rollback data hazards by providing data redundancy implemented in hardware. Compiler-based MIR designs were also developed which remove rollback data hazards directly with data flow manipulations, thus eliminating the need for most data redundancy hardware. Compiler-assisted techniques to achieve multiple instruction rollback recovery are addressed. It is observed that data some hazards resulting from instruction rollback can be resolved more efficiently by providing hardware redundancy while others are resolved more efficiently with compiler transformations. A compiler-assisted multiple instruction rollback scheme is developed which combines hardware-implemented data redundancy with compiler-driven hazard removal transformations. Experimental performance evaluations were conducted which indicate improved efficiency over previous hardware-based and compiler-based schemes. Various enhancements to the compiler transformations and to the data redundancy hardware developed for the compiler-assisted MIR scheme are described and evaluated. The final topic deals with the application of compiler-assisted MIR techniques to aid in exception repair and branch repair in a speculative execution architecture.

  18. A pedagogical shift from direct instruction: Technology-assisted inquiry learning (TAIL) in chemistry

    Science.gov (United States)

    Lou, Rena Zhihong

    The purpose of this study was to develop a student-centered Technology-Assisted Inquiry Learning (TAIL) pedagogical approach and compare it with the traditional, teacher-centered, direct instruction approach in a chemistry classroom. The study investigated how the TAIL approach affected community college chemistry students' (n = 21) learning gains and perceptions during a 1.5-hour intervention when compared with the direct instruction approach. A mixed methodology was used that included both quantitative and qualitative analyses. Results led to the following three key findings for novice learners: (a) TAIL had a statistically significant effect on students' procedural application skills improvement when compared with direct instruction; (b) The magnitude of the between-group difference (Cohen's d = 1.41) indicated that TAIL had a cumulative effect on students' learning gains due to its ability to incorporate multiple components including Inquiry, Guidance, Technology, and Collaboration; (c) When combining measures of students' performance and perceived mental effort, TAIL demonstrated high-instructional efficiency with a significant difference in teaching factual knowledge and procedural applications when compared with direct instruction. In summary, the outcome of this study demonstrated both the effectiveness and efficiency of the TAIL approach as a student-centered pedagogy in teaching a basic scientific topic. This study provided a practical demonstration of the pedagogical shift in teaching science from teacher-centered direct instruction to student-centered learning by using computer software as a pedagogical agent. The results of the study contribute to the literature in the fields of guided inquiry learning pedagogy and technology-assisted science teaching.

Decentralized agents submit bids to buy commodity and offers to sell transportation and commodity to a computerized dispatch center. Computer algorithms determine prices and allocations that maximize the gains from exchange in the system relative to the submitted bids and offers. The problem is important, because traditionally the scale and coordination economies in such industries were thought to require regulation. Laboratory experiments are used to study feasibility, limitations, incentives, and performance of proposed market designs for deregulation, providing motivation for new theory.

    2012-02-01

    The use of propofol for sedation in endoscopy may allow for better quality of sedation, quicker recovery and facilitate greater throughput in endoscopy units. The cost-effectiveness and utility of propofol sedation for endoscopic procedures is contingent on the personnel and resources required to carry out the procedure. Computer-based platforms are based on the patients response to stimulation and physiologic parameters. They offer an appealing means of delivering safe and effective doses of propofol. One such means is the bispectral index where continuous EEG recordings are used to assess the degree of sedation. Another is the closed-loop target-controlled system where a set of physical parameters, such as muscle relaxation and auditory-evoked potential, determine a level of medication appropriate to achieve sedation. Patient-controlled platforms may also be used. These electronic adjuncts may help endoscopists who wish to adopt propofol sedation to change current practices with greater confidence.

    2010-12-01

    There has been a recent acceleration in the development and testing of programs for computer-assisted cognitive-behavioral therapy (CCBT). Programs are now available for treatment of depression, anxiety disorders, and other psychiatric conditions. Technology for delivery of CCBT includes multimedia programs, virtual reality, and handheld devices. Research on CCBT generally has supported the efficacy of computer-assisted therapy and has shown patient acceptance of computer tools for psychotherapy. Completion rates and treatment efficacy typically have been higher when clinicians prescribe and support the use of psychotherapeutic computer programs than when programs are delivered in a self-help format without clinician involvement. CCBT seems to have the potential to improve access to evidence-based therapies while reducing the demand for clinician time.

This approach emphasizes the practices of "Developing and using models" and "Computational thinking" highlighted by the NRC K-12 science standards framework. We taught 9th-grade students in a Modeling-Instruction-based physics course to construct computational models using the VPython programming environment. Numerical computation within the Modeling Instruction curriculum provides coherence among the curriculum's different force and motion models, links the various representations which the curriculum employs, and extends the curriculum to include real-world problems that are inaccessible to a purely analytic approach.

    In the current study, behavior skills training (BST) is compared to a computer based training package for teaching discrete trial instruction to staff, teaching an adult with autism. The computer based training package consisted of instructions, video modeling and feedback. BST consisted of instructions, modeling, rehearsal and feedback. Following training, participants were evaluated in terms of their accuracy on completing critical skills for running a discrete trial program. Six participants completed training; three received behavior skills training and three received the computer based training. Participants in the BST group performed better overall after training and during six week probes than those in the computer based training group. There were differences across both groups between research assistant and natural environment competency levels.

  15. Computer-Assisted Surgery Using Telemanipulators

    Science.gov (United States)

    2004-01-01

    EXECUTIVE SUMMARY Objective The objective of this health technology policy assessment was to determine the effectiveness and cost-effectiveness of computer-assisted surgery with telemanipulators. The Technology The technology for computer-assisted surgery with telemanipulators is a robotic arm that carries an endoscope while two other manipulator arms carry interchangeable tools, such as scissors and grippers. In a master-slave telemanipulator system, the master may consist of a joystick input system, or for surgery, may mimic the motion of the slave robot, such as the da Vinci and ZEUS surgical systems. These systems are capable of telerobotic surgery, or surgery from remote locations. Review Strategy The Cochrane and INAHTA databases yielded 4 health technology assessments or systematic reviews on computer-assisted surgery using telemanipulators. A search of MEDLINE and EMBASE January 1, 2001 to November 24, 2003 was conducted. This search produced 448 studies, of which 19 met the inclusion criteria. Summary of Findings Published health technology assessments indicate that there are limited data from studies, although there is initial evidence of the safety and efficacy of telemanipulators in some procedures when they are used at large academic centres for surgery on selected patients. Most studies are Level 3 and 4 observational studies and assess a wide variety of surgical procedures. Limited studies indicate the promise of telemanipulators, but their efficacy is not fully established. In some procedures, the advantages that telemanipulators may offer may also be achieved by non-robotic minimally invasive/laparoscopic techniques. To date, cost-effectiveness has not been demonstrated. Patients who have undergone robotic surgery must be followed to further define outcomes (e.g., long-term quality of the graft after coronary arterial bypass graft [CABG] surgery). The exact role of computer-assisted surgery with telemanipulators has not been fully defined

    2002-04-01

    Full Text Available This paper addresses an indispensable skill using a unique method to teach a critical component: helping children learn to read by using computer-assisted oral reading to help children learn vocabulary. We build on Project LISTEN’s Reading Tutor, a computer program that adapts automatic speech recognition to listen to children read aloud, and helps them learn to read (http://www.cs.cmu.edu/~listen. To learn a word from reading with the Reading Tutor, students must encounter the word and learn the meaning of the word in context. We modified the Reading Tutor first to help students encounter new words and then to help them learn the meanings of new words. We then compared the Reading Tutor to classroom instruction and to human-assisted oral reading as part of a yearlong study with 144 second and third graders. The result: Second graders did about the same on word comprehension in all three conditions. However, third graders who read with the 1999 Reading Tutor, modified as described in this paper, performed statistically significantly better than other third graders in a classroom control on word comprehension gains – and even comparably with other third graders who read one-on-one with human tutors.

  17. Application of compiler-assisted multiple instruction rollback recovery to speculative execution

    1993-01-01

    Speculative execution is a method to increase instruction level parallelism which can be exploited by both super-scalar and VLIW architectures. The key to a successful general speculation strategy is a repair mechanism to handle mispredicted branches and accurate reporting of exceptions for speculated instructions. Multiple instruction rollback is a technique developed for recovery from transient processor failure. Many of the difficulties encountered during recovery from branch misprediction or from instruction re-execution due to exception in a speculative execution architecture are similar to those encountered during multiple instruction rollback. The applicability of a recently developed compiler-assisted multiple instruction rollback scheme to aid in speculative execution repair is investigated. Extensions to the compiler-assisted scheme to support branch and exception repair are presented along with performance measurements across ten application programs.

    This project is based on an entirely new concept for teaching the structure and function of the human body a concept which combines traditional approaches gained from centuries of study of human anatomy with the most recent sophisticated 3-dimensional computer graphics display systems and laser disc technology. The end-point of the project is a high resolution interactive 3-D atlas of human/animal anatomy stored on a laser video disc and displayed on graphics workstations--an " electronic Gray''s Anatomy" . These displays will be used to teach the structure of the body and to give students and instructors an understanding of their own body in health and disease. To evaluate the software developed undergraduate students from the anatomy courses at CSU wil be allowed to work with the computer-generated images from the earliest stages of development. Feedback from these students will be incorporated into the software development. Furthermore once a relatively complete series of images has been generated groups of students will be selected at random to study anatomy with this new methodology and will be compared with control groups who utilize more traditional techniques. METHODOLOGY This is a complex project that requires many individual facets to be developed simultaneously (figure 1). We have established an important collaboration with the Uniformed Services University in Bethesda that will allow us to utilize a large cryotome with photographic systems and the expertise to operate it already available there. Indeed most of the elaborate apparatus such as graphics workstations needed for the project is currently available either at CSU or through collaborative arrangements with other institutions.

    Full Text Available Pressure for better measurement of stated learning outcomes has resulted in a demand for more frequent assessment. The resources available are seen to be static or dwindling, but Information and Communications Technology is seen to increase productivity by automating assessment tasks. This paper reviews computer-assisted assessment (CAA and suggests future developments. A search was conducted of CAA-related literature from the past decade to trace the development of CAA from the beginnings of its large-scale use in higher education. Lack of resources, individual inertia and risk propensity are key barriers for individual academics, while proper resourcing and cultural factors outweigh technical barriers at the institutional level.

    1981-11-01

    A computer-assisted photo interpretation research (CAPIR) system has been developed at the U.S. Army Engineer Topographic Laboratories (ETL), Fort Belvoir, Virginia. The system is based around the APPS-IV analytical plotter, a photogrammetric restitution device that was designed and developed by Autometric specifically for interactive, computerized data collection activities involving high-resolution, stereo aerial photographs. The APPS-IV is ideally suited for feature analysis and feature extraction, the primary functions of a photo interpreter. The APPS-IV is interfaced with a minicomputer and a geographic information system called AUTOGIS. The AUTOGIS software provides the tools required to collect or update digital data using an APPS-IV, construct and maintain a geographic data base, and analyze or display the contents of the data base. Although the CAPIR system is fully functional at this time, considerable enhancements are planned for the future.

    We propose a method for computer-assisted optical biopsy for colorectal polyps, with the final goal of assisting the medical expert during the colonoscopy. In particular, we target the problem of automatic classification of polyp images in two classes: adenomatous vs non-adenoma. Our approach is based on recent advancements in convolutional neural networks (CNN) for image representation. In the paper, we describe and compare four different methodologies to address the binary classification task: a baseline with classical features and a Random Forest classifier, two methods based on features obtained from a pre-trained network, and finally, the end-to-end training of a CNN. With the pre-trained network, we show the feasibility of transferring a feature extraction mechanism trained on millions of natural images, to the task of classifying adenomatous polyps. We then demonstrate further performance improvements when training the CNN for our specific classification task. In our study, 776 polyp images were acquired and histologically analyzed after polyp resection. We report a performance increase of the CNN-based approaches with respect to both, the conventional engineered features and to a state-of-the-art method based on videos and 3D shape features.

    OBJECTIVES: The aim of this paper is to introduce the principles of computer-assisted access to the kidney. The system provides the surgeon with a pre-operative 3D planning on computed tomography (CT) images. After a rigid registration with space-localized ultrasound (US) data, preoperative planning can be transferred to the intra-operative conditions and an intuitive man-machine interface allows the user to perform a puncture. MATERIAL AND METHODS: Both CT and US images of informed normal volunteer were obtained to perform calculation on the accuracy of registration and punctures were carried out on a kidney phantom to measure the precision of the whole of the system. RESULTS: We carried out millimetric registrations on real data and guidance experiments on a kidney phantom showed encouraging results of 4.7 mm between planned and reached targets. We noticed that the most significant error was related to the needle deflection during the puncture. CONCLUSION: Preliminary results are encouraging. Further work w...

    Tracheal intubation via laryngoscopy is a fundamental skill, particularly for anaesthesiologists. However, teaching this skill is difficult since direct laryngoscopy allows only one individual to view the larynx during the procedure. The purpose of this study was to determine if video-assisted laryngoscopy improves the effectiveness of tracheal intubation training. In this prospective, randomized, crossover study, 37 novices with less than six prior intubation attempts were randomized into two groups, video-assisted followed by traditional instruction (Group V/T) and traditional instruction followed by video-assisted instruction (Group T/V). Novices performed intubations on three patients, switched groups, and performed three more intubations. All trainees received feedback during the procedure from an attending anaesthesiologist based on standard cues. Additionally, during the video-assisted part of the study, the supervising anaesthesiologist incorporated feedback based on the video images obtained from the fibreoptic camera located in the laryngoscope. During video-assisted instruction, novices were successful at 69% of their intubation attempts whereas those trained during the non-video-assisted portion were successful in 55% of their attempts (P=0.04). Oesophageal intubations occurred in 3% of video-assisted intubation attempts and in 17% of traditional attempts (Pvideo laryngoscopy for tracheal intubation training.

    Almost every engineering course involves mathematics in one form or another. The analytical process of developing mathematical models is very important for engineering students. However, the computational process involved in the solution of some mathematical problems may be very tedious and time consuming. There is a significant amount of mathematical software such as Mathematica, Mathcad, and Maple designed to aid in the solution of these instructional problems. The use of these packages in classroom teaching can greatly enhance understanding, and save time. Integration of computer technology in mathematics classes, without de-emphasizing the traditional analytical aspects of teaching, has proven very successful and is becoming almost essential. Sample computer laboratory modules are developed for presentation in the classroom setting. This is accomplished through the use of overhead projectors linked to graphing calculators and computers. Model problems are carefully selected from different areas.

    For the better part of the past 20 years, dentistry has seen the development of many new all-ceramic materials and restorative techniques fueled by the desire to capture the ever elusive esthetic perfection. This has resulted in the fusion of the latest in material science and the pen ultimate in computer-assisted design/computer-assisted manufacturing (CAD/CAM) technology. This case report describes the procedure for restoring the esthetic appearance of both the left and right maxillary peg-shaped lateral incisors with a metal-free sintered finely structured feldspar ceramic material using the latest laboratory CAD/CAM system. The use of CAD/CAM technology makes it possible to produce restorations faster with precision- fit and good esthetics overcoming the errors associated with traditional ceramo-metal technology. The incorporation of this treatment modality would mean that the dentist working procedures will have to be adapted in the methods of CAD/CAM technology.

    Profiles of fundamental frequency sound pressure levels and voice duration are measured separately in clinical practice. It was the aim of the present study to combine the two examinations, in order to estimate the relationship between pitch, sound pressure level and voice duration and to develop a new computer-assisted graph. A three-dimensional (3D) wireframe phonogram was constructed based on SPL profiles to obtain a general view of the parameters recorded. We have termed this "phonetography". Variable further projections were selected for the analysis of different aspects of parametric relationships. The results in 21 healthy volunteers and 4 patients with hyperfunctional dysphonias demonstrated that there were three typical figures of the 3D phonograms produced, depending on the relationship between voice duration when soft ("piano") compared to loud ("forte"). In one-third of the healthy volunteers, the values of the piano voice duration were greater than those of forte for almost all pitches examined. In two-thirds of the healthy subjects the values of forte voice duration were partly greater, as were those of piano voice duration. All of the patients showed voice duration values greater for forte than for piano. The results of the study demonstrate that the 3D phonogram is a useful tool for obtaining new insights into various relationships of voice parameters.

    Computer Assisted Rehabilitation Environment (CAREN) is a system that integrates a training platform (motion base), a virtual environment, a sensor system (motion capture) and D-flow software. It is useful for both diagnostic and therapeutic use. The human gait pattern can be impaired due to disease, trauma or natural decline. Gait analysis is a useful tool to identify impaired gait patterns. Traditional gait analysis is a very time consuming process and therefore only used in exceptional cases. With new systems a quick and extensive analysis is possible and provides useful tools for therapeutic purposes. The range of systems will be described in this paper, highlighting both their diagnostic use and the therapeutic possibilities. Because wounded warriors often have an impaired gait due to amputations or other extremity trauma, these systems are very useful for military rehabilitative efforts. Additionally, the virtual reality environment creates a very challenging situation for the patient, enhancing their rehabilitation experience. For that reason several Armed Forces have these systems already in use. The most recent experiences will be discussed; including new developments both in the extension of the range of systems and the improvement and adaptation of the software. A new and promising development, the use of CAREN in a special application for patients with post-traumatic stress disorder (PTSD), will also be reviewed.

    Systems for automated image analysis are useful for a variety of tasks and their importance is still increasing due to technological advances and an increase of social acceptance. Especially in the field of driver assistance systems the progress in science has reached a level of high performance. Fully or partly autonomously guided vehicles, particularly for road-based traffic, pose high demands on the development of reliable algorithms due to the conditions imposed by natural environments. At the Institut fur Neuroinformatik, methods for analyzing driving relevant scenes by computer vision are developed in cooperation with several partners from the automobile industry. We introduce a system which extracts the important information from an image taken by a CCD camera installed at the rear view mirror in a car. The approach consists of a sequential and a parallel sensor and information processing. Three main tasks namely the initial segmentation (object detection), the object tracking and the object classification are realized by integration in the sequential branch and by fusion in the parallel branch. The main gain of this approach is given by the integrative coupling of different algorithms providing partly redundant information.

    Femoral head resurfacing is re-emerging as a surgical option for younger patients who are not yet candidates for total hip replacement. However, this procedure is more difficult than total hip replacement, and the mechanical jigs typically used to align the implant produce significant variability in implant placement and take a significant amount of time to position properly. We propose that a computer-assisted surgical (CAS) technique could reduce implant variability with little or no increase in operative time. We describe a new CAS technique for this procedure and demonstrate in a cadaver study of five paired femurs that the CAS technique in the hands of a novice surgeon markedly reduced the varus/valgus variability of the implant relative to the pre-operative plan (2 degrees standard deviation for CAS versus 5 degrees for a mechanical jig operated by an expert surgeon). We also show that the mechanical jig resulted in significantly retroverted implant placement. There was no significant difference in operative time between the two techniques.

    The use of computers in the dental practice has been primarily restricted to the acquisition of billing data. Additional possibilities for use of PCs exist in diagnostic data acquisition and evaluation; clinical functional analysis seems a particularly suitable application. Such software is now available: CMDfact. Dentally, it is based on a previously developed and published examination and documentation system, the graphic user interface of which is used in the newly developed software. After the examination data have been acquired by mouse click or numerical entry, these are available for evaluation. A special function, the "Diagnosis pilot" is integrated to support the user. This helps in the assignment of the appropriate "Initial diagnoses", since it brings together the individually existing principal symptoms and suitable diagnoses for the initial diagnosis in question and also states which diagnoses "would be appropriate" for this, but are not available. With 3D animation, the software also helps the dentist to explain aspects of CMD to patients. The software also assists the dentist with a detailed multimedia help system, which provides context-sensitive help for every examination step. These help functions explain the sense of the relevant examinations, their performance and evaluation in the form of short texts and explanatory photographs and videos.

    Objective : Changes in small business and insurance present challenges for newly graduated chiropractors. Technology that reaches identified, diverse learning styles may assist the chiropractic student in business classes to meet course outcomes better. Thus, the purpose of our study is to determine if the use of technology-based instructional aids enhance students' mastery of course learning outcomes. Methods : Using convenience sampling, 86 students completed a survey assessing course learning outcomes, learning style, and the helpfulness of lecture and computer-assisted learning related to content mastery. Quantitative analyses occurred. Results : Although respondents reported not finding the computer-assisted learning as helpful as the lecture, significant relationships were found between pre- and post-assisted learning measures of the learning outcomes 1 and 2 for the visual and kinesthetic groups. Surprisingly, however, all learning style groups exhibited significant pre- and post-assisted learning appraisal relationships with learning outcomes 3 and 4. Conclusion : While evidence exists within the current study of a relationship between students' learning of the course content corollary to the use of technologic instructional aids, the exact nature of the relationship remains unclear.

However, many researchers believe the current studies are inadequate. While CBI software should be thoroughly tested by developers, as educators, we should be concerned about whether or not the CBI materials we use are improving learning in our classrooms with our students. We present an evaluation of a computer-based hypermedia tutorial that was delivered over our General Microbiology website. We found that CBI was at least as effective as text-based material. However, of all students who used CBI, only those who explored most of the site benefited from using the site. Tracking each student's use of the CBI was critical for understanding who was learning and why.

    Delays in starting first cases of the day are a common topic associated with high economic costs. This study aimed to determine if an operating room (OR) assistant using an instructional supervision program could reduce the tardiness of first-case starts. A prospective study was conducted. Data from four ORs were used to compare the effectiveness of an instructional intervention to reduce delays in starting first cases of the day. The first cases in two ORs received instructional supervision by an OR. The primary endpoint was the percentage of first cases that started on time. Other endpoints were the percentage of the team work score of OR staff and the percentage of patient satisfaction score. Over 48 weeks, the effect of instructional supervision was evaluated in 960 first-case starts. In the instructional supervision group (n = 480), the percentage of first cases that started on time increased significantly (92.1% vs 71.7%; P < .001), and there was a higher percentage of the team work score (84.4% vs 76.7%; P < .01) and patient satisfaction score (88.3% vs 79.4%; P < .001). Instructional supervision by an OR assistant can make a potential improvement in our on-time first-case starts per day. Copyright © 2016 American Society of PeriAnesthesia Nurses.

    The purpose of this study was to assess the effectiveness of computer-aided orthognathic surgery in reducing incisal overjet and establishing class I occlusion in subjects with dentofacial deformities. To address the research purpose, the investigators initiated a retrospective cohort study and enrolled a sample of subjects who underwent computer-assisted orthognathic surgery for dentofacial deformities. Two examiners assessed preoperative and postoperative lateral cephalometric radiographs for change in overjet after computer-assisted orthognathic surgery. Preoperative and postoperative occlusal photographs were then reviewed to assess for establishment of class I occlusion after computer-assisted orthognathic surgery. Cohen κ coefficient was used to assess for interrater agreement. A matched-pairs t-test was used to assess reduction in incisal overjet after computer-assisted orthognathic surgery. The sample was composed of 9 subjects who underwent computer-assisted surgery for dentofacial deformities. There was good interrater consistency for preoperative measurement of overjet (κ = 0.7, P ≤ 0.001). There was fair interrater consistency for postoperative measurement of overjet (κ = 0.4, P = 0 .02). Both examiners agreed on preoperative and postoperative assessments of occlusal photographs. There was a 3.4-mm reduction in incisal overjet after computer-assisted orthognathic surgery (P ≤ 0.001). Mean postoperative absolute overjet was 1.3 mm. In subjects with dentofacial deformities, computer-aided orthognathic surgery was effective in reducing incisal overjet and establishing class I occlusion.

  5. [The history and development of computer assisted orthopaedic surgery].

    Science.gov (United States)

    Jenny, J-Y

    2006-10-01

    Computer assisted orthopaedic surgery (CAOS) was developed to improve the accuracy of surgical procedures. It has improved dramatically over the last years, being transformed from an experimental, laboratory procedure into a routine procedure theoretically available to every orthopaedic surgeon. The first field of application of computer assistance was neurosurgery. After the application of computer guided spinal surgery, the navigation of total hip and knee joints became available. Currently, several applications for computer assisted surgery are available. At the beginning of navigation, a preoperative CT-scan or several fluoroscopic images were necessary. The imageless systems allow the surgeon to digitize patient anatomy at the beginning of surgery without any preoperative imaging. The future of CAOS remains unknown, but there is no doubt that its importance will grow in the next 10 years, and that this technology will probably modify the conventional practice of orthopaedic surgery.

  6. The application of compiler-assisted multiple instruction retry to VLIW architectures

    Science.gov (United States)

    Chen, Shyh-Kwei; Fuchs, W. K.; Hwu, Wen-Mei W.

    1994-01-01

    Very Long Instruction Word (VLIW) architectures enhance performance by exploiting fine-grained instruction level parallelism. We describe the development of two compiler assisted multiple instruction word retry schemes for VLIW architectures. The first scheme utilizes the compiler techniques previously developed for processors with single functional units. A compiler generated hazard-free code with different degrees of rollback capability for uniprocessors is compacted by a modified VLIW trace scheduling algorithm. Nops are then inserted in the scheduled code words to resolve data hazards for VLIW architectures. Performance is compared under three parameters: the rollback distance for uni-processors; the number of functional units; and the rollback distance for VLIW architectures. The second scheme employs a hardware read buffer to resolve frequently occurring data hazards, and utilizes the compiler to resolve the remaining hazards. Performance results are shown for six benchmark programs.

  15. Enhancing human-animal relationships through veterinary medical instruction in animal-assisted therapy and animal-assisted activities.

    Science.gov (United States)

    Schaffer, Caroline Brunsman

    2008-01-01

    Instruction in animal-assisted therapy (AAT) and animal-assisted activities (AAAs) teaches veterinary medical students to confidently and assertively maximize the benefits and minimize the risks of this union of animals and people. Instruction in AAT/AAA also addresses requirements by the American Veterinary Medical Association Council on Education that accredited schools/colleges of veterinary medicine include in their standard curriculum the topics of the human-animal bond, behavior, and the contributions of the veterinarian to the overall public and professional health care teams. Entry-level veterinarians should be prepared to: (1) assure that animals who provide AAT/AAA are healthy enough to visit nursing homes, hospitals, or other institutions; (2) promote behavior testing that selects animals who will feel safe, comfortable, and connected; (3) advise facilities regarding infection control and ways to provide a safe environment where the animals, their handlers, and the people being visited will not be injured or become ill; and (4) advocate for their patients and show compassion for their clients when animals are determined to be inappropriate participants in AAT/AAA programs. This article presents AAT/AAA terminology, ways in which veterinarians can advocate for AAT/AAA, the advantages of being involved in AAT/AAA, a model AAT/AAA practicum from Tuskegee University's School of Veterinary Medicine (TUSVM), and examples of co-curricular activities in AAT/AAA by TUSVM's student volunteers.

    Malin, M C; Sheridan, M F

    1982-08-13

    Volcanic hazard maps of surge boundaries and deposit thickness can be created by using a simplified eruption model based on an "energy line" concept of pyroclastic surge and flow emplacement. Computer image-processing techniques may be used to combine three-dimensional representations of the energy relations of pyroclasts moving under the influence of gravity (defined by an "energy cone") with digital topographic models of volcanoes to generate theoretical hazard maps. The deposit boundary and thickness calculated for the 18 May 1980 eruption of Mount St. Helens are qualitatively similar to those actually observed.

    1986-01-01

    The computer programs to design synthetic pathways of organic compounds have been utilized throughout the world since the first system was reported by Corey in 1969, and the LHASA was reported in1972 to become the predominant system. Many programs have been reported mainly in the United States and Europe, and groups of corporations, especially chemical companies, have been trying to improve programs and increase the efficiency of research. In Japan, unfortunately, no concrete movement in this area has been seen. Of course, it goes without saying that these kinds of programs are effective for efficient research, but the remarkable aspect is that these can present unexpected data to the researchers to stimulate them to develop new ideas.

    Puentes, John; Dhibi, Mounir; Bressollette, Luc; Guias, Bruno; Solaiman, Basel

    2009-03-01

    Venous thrombosis (VT) volume assessment, by verifying its risk of progression when anticoagulant or thrombolytic therapies are prescribed, is often necessary to screen life-threatening complications. Commonly, VT volume estimation is done by manual delineation of few contours in the ultrasound (US) image sequence, assuming that the VT has a regular shape and constant radius, thus producing significant errors. This paper presents and evaluates a comprehensive functional approach based on the combination of robust anisotropic diffusion and deformable contours to calculate VT volume in a more accurate manner when applied to freehand 2-D US image sequences. Robust anisotropic filtering reduces image speckle noise without generating incoherent edge discontinuities. Prior knowledge of the VT shape allows initializing the deformable contour, which is then guided by the noise-filtering outcome. Segmented contours are subsequently used to calculate VT volume. The proposed approach is integrated into a system prototype compatible with existing clinical US machines that additionally tracks the acquired images 3-D position and provides a dense Delaunay triangulation required for volume calculation. A predefined robust anisotropic diffusion and deformable contour parameter set enhances the system usability. Experimental results pertinence is assessed by comparison with manual and tetrahedron-based volume computations, using images acquired by two medical experts of eight plastic phantoms and eight in vitro VTs, whose independently measured volume is the reference ground truth. Results show a mean difference between 16 and 35 mm(3) for volumes that vary from 655 to 2826 mm(3). Two in vivo VT volumes are also calculated to illustrate how this approach could be applied in clinical conditions when the real value is unknown. Comparative results for the two experts differ from 1.2% to 10.08% of the smallest estimated value when the image acquisition cadences are similar.

    2014-11-01

    Full Text Available In a world in which IT is developing faster than ever, providing reliable solutions to all problems, regardless the field of interest, the issue of computer-assisted translation systems is more and more complex, offering both advantages and disadvantages. The field of translating legal texts from Romanian into English is deprived of a large number of specialists and this is one of the main reasons why more and more people resort to computer-assisted translations, especially Google translations when dealing with translating various texts (from Romanian into English or vice-versa, in this particular case legal texts. Yet, although this field has immensely thrived recently, and is quite reliable for simple and very easy translations, the average English speaker runs huge risks of falling into traps that can lead to errors and misinterpretations. Thus, this article aims to identify the main theoretical approaches to computer-assisted theories and the major risks and threats that occur in this type of translation, focusing particularly on legal texts. There are important differences, not only of words, but also differences in the legal systems themselves, both theoretical and practical ones, which must be correctly dealt with -something which computer-assisted translation cannot do (yet.

    2016-03-01

    Considering computers are more efficient at processing large amounts of information than the human brain, speaks to the need to explore more intelligent computer-assisted diagnostic approaches. Two diagnostic checklist programs, one for single key term entry (NeurologyINDEX), and another, with more advanced algorithms to process multiple key terms and perform additional functions (NeurologicDx) are discussed. Both programs are internet based, access the same database, and are designed to generate diagnostic checklists and disease profiles accessible with hand-held or other computer device. The development of systems that use "smart algorithms" to generate valid diagnostic checklists is the goal.

  12. Computer assisted orthopaedic surgery: present status and future perspectives

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    @@ The principle of navigation surgery was first adopted in neurosurgery where a mechanical rigid frame was used in the stereotactic surgery to locate a deep ganglia and tract in the brain by Clark and Horsley1 in 1906. The planning was based on anatomical atlas of the brain and was not patient specific. The navigation procedure was possible with a rigid mechanical frame to define the trajectory with a rigid instrument holder on a rigid fixation of the operating structure, i.e. the skull. With the advancements in 3-D medical imaging, i.e. CT in 1971,MR imaging in 1973, general stereotaxis was possible and became specific to anatomy of each individual patient.Together with the advancement of computer technology:VAX in 1976, Apple in 1977, IBM personal computer in 1981, computer assisted stereotaxis was possible and in 1985, the term computer assisted surgery (CAS) was proposed by Sohn and Robins.2 With further development of 3-D tracking by NDI with Optotrak 1990, computer assisted orthopaedic surgery (CAOS) developed and gradually became widely applicable in clinical practice.

    2008-01-01

    There are an increasing number of studies about the computer-assisted dental patient simulator DentSim (DenX, Israel), by which dental students can acquire cognitive motor skills in a multimedia environment. However, only a very few studies have been published dealing with efficient ways to use and to manage a computer-assisted dental simulation lab with 40 DentSim units. The current approach and optimization steps of the College of Dentistry at the University of Tennessee Health Science Center were evaluated based on theoretical and practical tests and by questionnaires (partial 5-point Likert scale). Half of the D1 (first-year) students (2004/05) already had experience with computer-assisted learning at their undergraduate college and most of the students even expected to be taught via computer-assisted learning systems (83.5%) at the dental school. 87.3% of the students working with DentSim found the experience to be very interesting or interesting. Before the students carried out the preparation exercises, they were trained in the skills they needed to work with the sophisticated technology, eg, system-specific operation skills (66.6% attained maximal reachable points) and information searching skills (79.5% attained maximal reachable points). The indirect knowledge retention rate / incidental learning rate of the preparation exercises in the sense of computer-assisted problem-oriented learning regarding anatomy, preparation procedures, and cavity design was promising. The wide- ranging number of prepared teeth needed to acquire the necessary skills shows the varied individual learning curves of the students. The acceptance of, and response to, additional elective training time in the computer-assisted simulation lab were very high. Integrating the DentSim technology into the existing curriculum is a way to improve dental education, but it is also a challenge for both teachers and the students. It requires a shift in both curriculum and instructional goals that

    Venkatesan, Muralidharan; Mahadevan, Devendra; Ashford, Robert U

    2013-10-01

    The purpose of this review was to appraise the use of computer-assisted navigation in total knee arthroplasty and to assess whether this technology has improved clinical outcomes. Studies were identified through searches in MEDLINE, Embase, and PubMed. Numerous studies have shown improved leg and component alignment using navigation systems. However, the better alignment achieved in navigated knee arthroplasty has not been shown to lead to better clinical outcomes. Navigated knee arthroplasty had lower calculated blood loss and lower incidence of fat embolism compared with conventional knee arthroplasty using intramedullary jigs. It may be most valued when dealing with complex knee deformities, revision surgery, or minimally invasive surgery. Navigated knee arthroplasty, however, is only cost-effective in centers with a high volume of joint replacements. Overall, computer-assisted navigated knee arthroplasty provides some advantages over conventional surgery, but its clinical benefits to date are unclear and remain to be defined on a larger scale.

  1. Soft Tissue Biomechanical Modeling for Computer Assisted Surgery

    CERN Document Server

    2012-01-01

      This volume focuses on the biomechanical modeling of biological tissues in the context of Computer Assisted Surgery (CAS). More specifically, deformable soft tissues are addressed since they are the subject of the most recent developments in this field. The pioneering works on this CAS topic date from the 1980's, with applications in orthopaedics and biomechanical models of bones. More recently, however, biomechanical models of soft tissues have been proposed since most of the human body is made of soft organs that can be deformed by the surgical gesture. Such models are much more complicated to handle since the tissues can be subject to large deformations (non-linear geometrical framework) as well as complex stress/strain relationships (non-linear mechanical framework). Part 1 of the volume presents biomechanical models that have been developed in a CAS context and used during surgery. This is particularly new since most of the soft tissues models already proposed concern Computer Assisted Planning, with ...

    Phillips, R; Hafez, M A; Mohsen, A M; Sherman, K P; Hewitt, J R; Browbank, I; Bouazza-Marouf, K

    2000-01-01

    The outcome variability and failures of conventional osteotomy have been attributed to lack of preoperative planning and inaccuracy in performing the correction. We present a computer and robotic assisted surgery system that can aid in accurate surgical planning for realignment, and in precisely implementing the plan in theatre. The approach seeks to avoid the cost and risks associated with the use of CT, and the insertion of fiducial markers, which are characteristic of existing computer assisted surgical systems. The paper details the architecture of the system as a whole, placing particular emphasis on planning technique. It is anticipated that the increased accuracy possible with the system will prove particularly useful for correcting multi-plane deformities, which are more problematic with conventional techniques.

    The objective of this project was to provide a prototype that would enhance training and could be used as a shipboard refresher and retraining tool. The prototype system will be installed onboard ships where Navy personnel will have ready access to the training. Subsequent testing and evaluation of the prototype could provide the basis for a Navy-wide effort to implement computer aided instruction. The design and development stages of the project followed a rigorous structured analysis methodology based on the Yourdon/DeMarco techniques. Data flow diagrams and a data dictionary were developed, which served as guideposts for the analysts throughout the remainder of the project. Additionally, a method for automatically generating standardized COBOL code using a data management system was developed. When compiled, the generated code accounted for greater than half of the prototype system. The problems encountered during design and development revolved around requirements to use existing hardware, software, and programmer capabilities for development, implementation, and maintenance of the instructional software. Solutions were developed which will allow the software to exist in the given environment and still provide advanced features not available in commercial courseware systems, including: (1) a customized help option with diagrams and descriptions of the SNAP-1 terminal keyboard and a glossary of Navy terms and acronyms; (2) a security system which provides information to assist the course monitor in determining that the person assigned was actually the person who took the course; (3) an intelligent interface that enables the student to ask questions, make comments, and get replies, which simulate live student-teacher interaction; and (4) an online evaluation of the course by the student.

    We propose a scheme for scalable photonic quantum computation based on cavity-assisted interaction between single-photon pulses. The prototypical quantum controlled phase-flip gate between the single-photon pulses is achieved by successively reflecting them from an optical cavity with a single-trapped atom. Our proposed protocol is shown to be robust to practical noise and experimental imperfections in current cavity-QED setups.

    2010-06-01

    Results of the efficacy and time efficiency of computer-assisted learning (CAL) in endodontics education are mixed in the literature. The objectives of this study were to compare the efficacy and time efficiency of CAL with traditional learning methods or no instruction. The search strategy included electronic and manual searches of randomized controlled trials (RCTs) completed in English up to June 2009. The intervention comprised any method of CAL, while the control group consisted of all traditional methods of instruction including no further instructions. Various outcome measures of CAL efficacy were considered and were categorized using Kirkpatrick's four-level model of evaluation: reaction, learning, behavior, results, with the addition of return on investment as a fifth level. The time efficiency of CAL was measured by the time spent on the learning material and the number of cases covered in a unit period. Seven RCTs met the inclusion criteria. Overall, students' attitudes were varied towards CAL. Results from the knowledge gain outcome were mixed. No conclusions can be made about students' performance on clinical procedures or cost-effectiveness of CAL. Better time efficiency was achieved using CAL compared to traditional methods. CAL is as efficacious as traditional methods in improving knowledge. There is some evidence to suggest that CAL is time efficient compared to traditional methods. Overall, the number of studies included in this review was small, thus warranting the need for more studies in this area and the exploration of various CAL techniques.

  7. COMPUTER ASSISTED LOOM IN THE REVIVAL OF CONTEMPORARY MONUMENTAL TAPESTRY

    Directory of Open Access Journals (Sweden)

    PINTILIE Anca-Aurelia

    2015-05-01

    Full Text Available The art of tapestry has its basics back in time, probably in the decorations of tent, the house of the nomad. Tapestry in its beginnings is the first wall of the nomad’s home and the decorative wall and canopy in the ancient Greek houses as architect Gottfried Semper stated in the nineteen century. The architectural approach is not unusual even in the next centuries. Tapestry becomes popular as a form of monumental art during the Middle Ages when it is used as decorative architectural element, coating the walls of medieval castles. During the next centuries dominated by decadent styles of baroque, rococo, the tapestry will lose its monumental spirit and architectural quality but at the middle of the XXth century a new approach will sustain the revival of the tapestry as monumental art. Later, in the XXIst century, renowned multimedia artists will approach this medium and will use computer assisted looms in ambitious tapestry projects. This technique will allow them to realize complex and exquisite tapestries, sustaining in this way the revival of the tapestry in the contemporary art world. The paper presents the importance of the architectural side of tapestry and the great achievement that computer assisted loom represents for this form of art. The research activity is willing to inform Romanian textile designers about the possibilities to create tapestries on computer assisted looms. The research was made during the initial stage of a doctoral thesis consisting in a documentary study on monumental aspects of contemporary tapestry.

    2012-04-01

    Incorrect resection of the patella during total knee arthroplasty (TKA) can lead to anterior knee pain (AKP), patellar maltracking, patellofemoral impingement, patellar fracture, component loosening, and reduced range of motion. Computer-assisted surgery (CAS) systems for the tibia and femur improve cut accuracy, but no CAS system is available for patellar resection. We developed a system that included an optoelectronic localizer, marker arrays on the patella and instruments, and navigation software. Three users performed resections on artificial patellae mounted in a simulated surgical setup using five techniques (two CAS, three conventional), each repeated at least three times in randomized order. Computer-assisted patellar resection produced better or equal cut symmetry compared to conventional techniques, particularly superoinferiorly. Using CAS with a sawguide produced better results than using CAS freehand with an oscillating saw. This study showed the feasibility of computer-assisted patellar resection, which could lead to reduced pain and complications after TKA. The feedback provided could also make patellar CAS a valuable training tool.

    Tao, Ping-Kee

    2004-10-01

    This article reports the use of a computer-based collaborative learning instruction designed to help students develop understanding of image formation by lenses. The study aims to investigate how students, working in dyads and mediated by multimedia computer-assisted learning (CAL) programs, construct shared knowledge and understanding. The subjects were a class of 36 Secondary 4 (Year 10) students working in dyads throughout the instruction. The instruction comprised three stages (namely, pre-test, computer-based activity, and posttest), during which students' within-dyad interactions were audio-recorded and transcribed for analysis. Three months after the instruction, some selected students were interviewed individually. The pre-test result showed that many students held the 'holistic conceptualizations' of image formation (rather than the physicists' point-to-point mapping model), which they applied to give alternative answer/explanations to the questions in the test. The post-test and interviews showed that overall, students improved their understanding of image formation although the improvement ranged widely. The rich qualitative data of peer interactions show that students experienced conflicts and co-construction that fostered their intensive engagement with tasks and with each other. The data also show the mediating role of the CAL programs and the teacher that helped students develop understanding.

    Full Text Available We focus on how to securely outsource computation task to the cloud and propose a secure outsourcing multiparty computation protocol on lattice-based encrypted data in two-cloud-servers scenario. Our main idea is to transform the outsourced data respectively encrypted by different users’ public keys to the ones that are encrypted by the same two private keys of the two assisted servers so that it is feasible to operate on the transformed ciphertexts to compute an encrypted result following the function to be computed. In order to keep the privacy of the result, the two servers cooperatively produce a custom-made result for each user that is authorized to get the result so that all authorized users can recover the desired result while other unauthorized ones including the two servers cannot. Compared with previous research, our protocol is completely noninteractive between any users, and both of the computation and the communication complexities of each user in our solution are independent of the computing function.

    Physical rehabilitation supported by the computer-assisted-interface is gaining popularity among health-care fraternity. In this paper, we have proposed a computer-vision-assisted contactless methodology to facilitate palm and finger rehabilitation. Leap motion controller has been interfaced with a computing device to record parameters describing 3-D movements of the palm of a user undergoing rehabilitation. We have proposed an interface using Unity3D development platform. Our interface is capable of analyzing intermediate steps of rehabilitation without the help of an expert, and it can provide online feedback to the user. Isolated gestures are classified using linear discriminant analysis (DA) and support vector machines (SVM). Finally, a set of discrete hidden Markov models (HMM) have been used to classify gesture sequence performed during rehabilitation. Experimental validation using a large number of samples collected from healthy volunteers reveals that DA and SVM perform similarly while applied on isolated gesture recognition. We have compared the results of HMM-based sequence classification with CRF-based techniques. Our results confirm that both HMM and CRF perform quite similarly when tested on gesture sequences. The proposed system can be used for home-based palm or finger rehabilitation in the absence of experts.

    Open heart bypass surgery is the standard treatment in advanced coronary heart diseases. For an effective revascularization procedure, optimal placement of the bypass is very important. To accelerate the intraoperative localization of the anastomosis site and to increase the precision of the procedure, a concept for computer assistance in open heart bypass surgery has been developed comprising the following steps: 1. Preprocedural planning: A patient-specific coronary map with information on vessel paths and wall plaque formations is extracted from a multi-slice computed tomography (MSCT). On this basis, the heart surgeon and the cardiac radiologist define the optimal anastomosis site prior to surgery. 2. Intraoperative navigation: During surgery, data are recorded at the beating heart using a stereo camera system. After registering the pre- and intraoperative data sets, preprocedural information can be transferred to the surgical site by overlaying the coronary map and the planned anastomosis site on the live video stream. With this visual guidance system, the surgeon can navigate to the planned anastomosis site. In this work, the proposed surgical assistance system has been validated for the left anterior descending coronary artery (LAD). The accuracy of the registration mechanism has been evaluated in retrospective on patient data sets and the effects of breathing motion were quantified. The promising results of the retrospective evaluation led to the in-vivo application of the computer assistance system during several bypass grafting procedures. Intraoperative navigation has been performed successfully and postoperative evaluation confirms that the bypass grafts were accurately positioned to the preoperatively planned anastomosis sites.

    To make the surgical procedure safer and more precise in FESS, a non-invasive markerless computer-assisted system (CAS) is described for intra-operative navigation whenever the critical regions may be affected by surgical manipulation. Twenty patients with benign diseases of the paranasal sinuses were treated by Computer Assisted Video-endoscopic surgery, between December 1997 and March 1998. For the determination of accuracy and reproducibility of the system, ten anatomical landmarks on each side of the paranasal sinuses were chosen and measured. All of these points were identified on the direct live video-endoscopy image and compared to those obtained with the Optical Digitizing System (Flashpoint 5000(R)), on axial, coronal and sagittal view. The Optical Localizer we used detects the position of the relative coordinates of two rigid bodies made of IR-LED's each, one rigid body is secured to the head' of the patient with a headset, so that patient motion can be tracked, and the second rigid body attached to the operating instrument, leading to direct localization of the tip of the instrument. We use a markerless, skin surface-based registration method, which has the advantage to avoid doing a second CT scan examination usually performed to process the position of the fiducial markers. We register the data from the patient's usual paranasal CT scan. Computer-assisted surgery does not increase significantly the duration of the operation. Our markerless skin surface points registration method is reliable enabling of the movements patient's head during the procedure. Computer assistance can be used in almost any type of endoscopic sinonasal procedure. We obtained a registration and calibration accuracy of less than 1.5 mm in 89.2% of cases. CAS enables the surgeon to have a more thorough understanding of the complicated anatomy of paranasal sinuses, and may be especially helpful in revision surgery when normal anatomic landmarks are lacking. Due to the passive

    The precise slice geometry of a CT scanner is an important, albeit tedious to determine, characteristic. A series of computer programs have been developed to analyze the slice thickness insert of the AAPM phantom. Without operator assistance they generate the beam profiles and slice thicknesses at three points in the scan field. A representative analysis is done on an AS&E scanner with slice thickness settings of 2 to 10 mm. The resulting discrepent measured thicknesses, ranging from 3 to 8 mm, indicate the need to perform such slice thickness measurements as part of a regular quality assurance program.

    Users with disabilities interact with Personal Computers (PCs) using Assistive Technology (AT) software solutions. Such applications run on a PC that a person with a disability commonly uses. However the configuration of AT applications is not trivial at all, especially whenever the user needs to work on a PC that does not allow him/her to rely on his / her AT tools (e.g., at work, at university, in an Internet point). In this paper, we discuss how cloud computing provides a valid technological solution to enhance such a scenario.With the emergence of cloud computing, many applications are executed on top of virtual machines (VMs). Virtualization allows us to achieve a software implementation of a real computer able to execute a standard operating system and any kind of application. In this paper we propose to build personalized VMs running AT programs and settings. By using the remote desktop technology, our solution enables users to control their customized virtual desktop environment by means of an HTML5-based web interface running on any computer equipped with a browser, whenever they are.

    Introduction. Surgical tooth extraction is a common procedure in dentistry. However, numerous extraction cases show a high level of difficulty in practice. This difficulty is usually related to inadequate visualization, improper instrumentation, or other factors related to the targeted tooth (e.g., ankyloses or presence of bony undercut). Methods. In this work, the author presents a new technique for surgical tooth extraction based on 3D imaging, computer planning, and a new concept of computer-assisted manufacturing. Results. The outcome of this work is a surgical guide made by 3D printing of plastics and CNC of metals (hybrid outcome). In addition, the conventional surgical cutting tools (surgical burs) are modified with a number of stoppers adjusted to avoid any excessive drilling that could harm bone or other vital structures. Conclusion. The present outcome could provide a minimally invasive technique to overcome the routine complications facing dental surgeons in surgical extraction procedures.

    Cartographic models addressing a wide variety of applications are composed of fundamental map processing operations. These primitive operations are neither data base nor application-specific. By organizing the set of operations into a mathematical-like structure, the basis for a generalized cartographic modeling framework can be developed. Among the major classes of primitive operations are those associated with reclassifying map categories, overlaying maps, determining distance and connectivity, and characterizing cartographic neighborhoods. The conceptual framework of cartographic modeling is established and techniques for characterizing neighborhoods are used as a means of demonstrating some of the more sophisticated procedures of computer-assisted map analysis. A cartographic model for assessing effective roundwood supply is briefly described as an example of a computer analysis. Most of the techniques described have been implemented as part of the map analysis package developed at the Yale School of Forestry and Environmental Studies.

    In recent years, computer assisted surgery (CAS) systems become more and more common in clinical practices, but few specific design criteria have been proposed for human-computer interface (HCI) in CAS systems. This paper tried to give universal criteria of HCI design for CAS systems through introduction of demonstration application, which is total knee replacement (TKR) with a nonimage-based navigation system.A typical computer assisted process can be divided into four phases: the preoperative planning phase, the intraoperative registration phase, the intraoperative navigation phase and finally the postoperative assessment phase. The interface design for four steps is described respectively in the demonstration application. These criteria this paper summarized can be useful to software developers to achieve reliable and effective interfaces for new CAS systems more easily.

    The most advanced methods for reliable and accurate computation of the electronic structure of molecular and nano systems are the coupled-cluster techniques. These high-accuracy methods help us to understand, for example, how biological enzymes operate and contribute to the design of new organic explosives. The ACES III software provides a modern, high-performance implementation of these methods optimized for high performance parallel computer systems, ranging from small clusters typical in individual research groups, through larger clusters available in campus and regional computer centers, all the way to high-end petascale systems at national labs, including exploiting GPUs if available. This project enhanced the ACESIII software package and used it to study interesting scientific problems.

    Full Text Available Purpose. The purpose of this study was to determine whether intraoperative prereconstruction stability measurements and/or patient characteristics were associated with final knee stability after computer-assisted ACL reconstruction. Methods. This was a retrospective review of all patients who underwent computer-assisted single-bundle ACL reconstruction by a single surgeon. Prereconstruction intraoperative stability measurements were correlated with patient characteristics and postreconstruction stability measurements. 143 patients were included (87 male and 56 female. Average age was 29.8 years (SD ± 11.8. Results. Females were found to have significantly more pre- and postreconstruction internal rotation than males (P < 0.001 and P = 0.001, resp.. Patients with additional intra-articular injuries demonstrated more prereconstruction anterior instability than patients with isolated ACL tears (P < 0.001. After reconstruction, these patients also had higher residual anterior translation (P = 0.01. Among all patients with ACL reconstructions, the percent of correction of anterior translation was found to be significantly higher than the percent of correction for internal or external rotation (P < 0.001. Conclusion. Anterior translation was corrected the most using a single-bundle ACL reconstruction. Females had higher pre- and postoperative internal rotation. Patients with additional injuries had greater original anterior translation and less operative correction of anterior translation compared to patients with isolated ACL tears.

    Percutaneous nephrolithotomy (PCNL) plays an integral role in treatment of renal stones. Creating percutaneous renal access is the most important and challenging step in the procedure. To facilitate this step, we evaluated our novel mobile augmented reality (AR) system for its feasibility of use for PCNL. A tablet computer, such as an iPad[Formula: see text], is positioned above the patient with its camera pointing toward the field of intervention. The images of the tablet camera are registered with the CT image by means of fiducial markers. Structures of interest can be superimposed semi-transparently on the video images. We present a systematic evaluation by means of a phantom study. An urological trainee and two experts conducted 53 punctures on kidney phantoms. The trainee performed best with the proposed AR system in terms of puncturing time (mean: 99 s), whereas the experts performed best with fluoroscopy (mean: 59 s). iPad assistance lowered radiation exposure by a factor of 3 for the inexperienced physician and by a factor of 1.8 for the experts in comparison with fluoroscopy usage. We achieve a mean visualization accuracy of 2.5 mm. The proposed tablet computer-based AR system has proven helpful in assisting percutaneous interventions such as PCNL and shows benefits compared to other state-of-the-art assistance systems. A drawback of the system in its current state is the lack of depth information. Despite that, the simple integration into the clinical workflow highlights the potential impact of this approach to such interventions.

    2010-01-01

    Background The use of computers has increased among adolescents, as have musculoskeletal symptoms. There is evidence that these symptoms can be reduced through an ergonomics approach and through education. The purpose of this study was to examine where adolescents had received ergonomic instructions related to computer use, and whether receiving these instructions was associated with a reduced prevalence of computer-associated health complaints. Methods Mailed survey with nationally representative sample of 12 to 18-year-old Finns in 2001 (n = 7292, response rate 70%). In total, 6961 youths reported using a computer. We tested the associations of computer use time and received ergonomic instructions (predictor variables) with computer-associated health complaints (outcome variables) using logistic regression analysis. Results To prevent computer-associated complaints, 61.2% reported having been instructed to arrange their desk/chair/screen in the right position, 71.5% to take rest breaks. The older age group (16-18 years) reported receiving instructions or being self-instructed more often than the 12- to 14-year-olds (p computer-associated health complaints. Conclusions This report shows that ergonomic instructions on how to prevent computer-related musculoskeletal problems fail to reach a substantial number of children. Furthermore, the reported sources of instructions vary greatly in terms of reliability. PMID:20064250

    The use of perfusion imaging to guide selection of patients for stroke thrombolysis remains controversial because of lack of supportive phase three clinical trial evidence. We aimed to measure the outcomes for patients treated with intravenous recombinant tissue plasminogen activator (rtPA) at a comprehensive stroke care facility where perfusion computed tomography was routinely used for thrombolysis eligibility decision assistance. Our overall hypothesis was that patients with ‘target’ mismatch on perfusion computed tomography would have improved outcomes with rtPA. This was a prospective cohort study of consecutive ischaemic stroke patients who fulfilled standard clinical/non-contrast computed tomography eligibility criteria for treatment with intravenous rtPA, but for whom perfusion computed tomography was used to guide the final treatment decision. The ‘real-time’ perfusion computed tomography assessments were qualitative; a large perfusion computed tomography ischaemic core, or lack of significant perfusion lesion-core mismatch were considered relative exclusion criteria for thrombolysis. Specific volumetric perfusion computed tomography criteria were not used for the treatment decision. The primary analysis compared 3-month modified Rankin Scale in treated versus untreated patients after ‘off-line’ (post-treatment) quantitative volumetric perfusion computed tomography eligibility assessment based on presence or absence of ‘target’ perfusion lesion-core mismatch (mismatch ratio >1.8 and volume >15 ml, core perfusion computed tomography-selected rtPA-treated patients to an Australian historical cohort of non-contrast computed tomography-selected rtPA-treated patients. Of 635 patients with acute ischaemic stroke eligible for rtPA by standard criteria, thrombolysis was given to 366 patients, with 269 excluded based on visual real-time perfusion computed tomography assessment.

    Full Text Available Abstract Background The use of computers has increased among adolescents, as have musculoskeletal symptoms. There is evidence that these symptoms can be reduced through an ergonomics approach and through education. The purpose of this study was to examine where adolescents had received ergonomic instructions related to computer use, and whether receiving these instructions was associated with a reduced prevalence of computer-associated health complaints. Methods Mailed survey with nationally representative sample of 12 to 18-year-old Finns in 2001 (n = 7292, response rate 70%. In total, 6961 youths reported using a computer. We tested the associations of computer use time and received ergonomic instructions (predictor variables with computer-associated health complaints (outcome variables using logistic regression analysis. Results To prevent computer-associated complaints, 61.2% reported having been instructed to arrange their desk/chair/screen in the right position, 71.5% to take rest breaks. The older age group (16-18 years reported receiving instructions or being self-instructed more often than the 12- to 14-year-olds (p Conclusions This report shows that ergonomic instructions on how to prevent computer-related musculoskeletal problems fail to reach a substantial number of children. Furthermore, the reported sources of instructions vary greatly in terms of reliability.

  12. Is Computer-assisted Distance Learning Possible in Nematology?

    In many institutions of higher education, introductory nematology is taught to small numbers of students. Nematology and other low-enrollment courses may be placed under scrutiny, reformatted, or dropped from the curriculum to cut costs and improve faculty efficiency. Computer-assisted distance education (CADE) offers a way to increase faculty productivity and job satisfaction, student learning and socialization, and cost-effectiveness. Participating institutions gain by sharing resources with other schools and may retain or even increase enrollments through broadened educational opportunities. CADE ranges from complete course offerings and video interaction to supplemental materials on a personal computer for independent learning. A modular approach to course development is the most successfuI model because of the flexibility it offers. While an entire hematology course through CADE is not possible without substantial institutional and faculty investment, supplemental materials can help remotely located students gain an appreciation for hematology. Nematological images, text, computer programs, and other resources can easily be placed on Internet web pages. Nematologists in all sectors need to continue to reach out to the next generation of leaders to tell them what nematologists do and why nematodes are important. The Society of Nematologists can be a leader in the systematic development of CADE in nematology.

  14. Computer assisted screening, correction, and analysis of historical weather measurements

    Science.gov (United States)

    Burnette, Dorian J.; Stahle, David W.

    2013-04-01

    A computer program, Historical Observation Tools (HOB Tools), has been developed to facilitate many of the calculations used by historical climatologists to develop instrumental and documentary temperature and precipitation datasets and makes them readily accessible to other researchers. The primitive methodology used by the early weather observers makes the application of standard techniques difficult. HOB Tools provides a step-by-step framework to visually and statistically assess, adjust, and reconstruct historical temperature and precipitation datasets. These routines include the ability to check for undocumented discontinuities, adjust temperature data for poor thermometer exposures and diurnal averaging, and assess and adjust daily precipitation data for undercount. This paper provides an overview of the Visual Basic.NET program and a demonstration of how it can assist in the development of extended temperature and precipitation datasets using modern and early instrumental measurements from the United States.

    In this work is presented the development of a mechatronics device to simulate the interaction of the surgeon with the surgical instrument (resectoscope) used during a Transurethral Resection of the Prostate (TURP). Our mechatronics interface is part of a computer assisted system for training in TURP, which is based on a 3D graphics model of the prostate which can be deformed and resected interactively by the user. The mechatronics interface, is the device that the urology residents will manipulate to simulate the movements performed during surgery. Our current prototype has five degrees of freedom, which are enough to have a realistic simulation of the surgery movements. Two of these degrees of freedom are linear, to determinate the linear displacement of the resecting loop and the other three are rotational to determinate three directions and amounts of rotation.

    1993-12-01

    A new integrated computer-assisted personalized assignment (CAPA) system that creates individual assignments for each student has been developed and found to be a powerful motivator. The CAPA system allows students to enter their answers to personalized assignments directly via networked terminals, gives immediate feedback and hints (allowing challenging questions), while providing the instructor with on-line performance information. The students are encouraged to study together which is known to be an effective learning strategy, but each must still obtain his/her own correct answers. Students are allowed to re-enter solutions to the problems before the due date without penalty, thus providing students with different skills levels the opportunity and incentive to understand the material without being judged during the learning process. The features and operation of the system are described, observations on its use in an introductory general physics class are reported, and some of the highly favorable student reactions are included.

  19. Translation Memory and Computer Assisted Translation Tool for Medieval Texts

    2013-05-01

    Full Text Available Translation memories (TMs, as part of Computer Assisted Translation (CAT tools, support translators reusing portions of formerly translated text. Fencing books are good candidates for using TMs due to the high number of repeated terms. Medieval texts suffer a number of drawbacks that make hard even “simple” rewording to the modern version of the same language. The analyzed difficulties are: lack of systematic spelling, unusual word orders and typos in the original. A hypothesis is made and verified that even simple modernization increases legibility and it is feasible, also it is worthwhile to apply translation memories due to the numerous and even extremely long repeated terms. Therefore, methods and algorithms are presented 1. for automated transcription of medieval texts (when a limited training set is available, and 2. collection of repeated patterns. The efficiency of the algorithms is analyzed for recall and precision.

    1997-12-01

    In the project entitled “Computer-Assisted Collision Avoidance”, which was funded by the German Mi nistry of Education, Research and Technology and was executed in cooperation with the industrial partner STN ATLAS Elektronik, the intention was to combine the tasks of track planning, track control and collision avoidance. The aim was to develop a system which would support the officer of the watch in the handling of complex traffic situations by suggesting collision-avoidance tracks. The main points of this project were in the following areas: p] Determination and display of danger areas The positions of possible collisions with other ships, and areas to be avoided on the basis of defined closest points of approach, are computed and displayed with geometrical exactness. The target ships are fed into the system via a standardized interface. Set of rules for the handling of multi- ship encounters The software for computer-assisted collision avoidance contains a set of rules for the creation of collisi on avoidance tracks, taking account of the existing traffic situation. This set of rules takes into account the International Regulations for Preventing Collisions at Sea (COLREG) and nautical practice. In the process of generating a track suggestion, all other ships detected in the sea area concerned are included in the compu tation. Integration of ECDIS One of the main aims of the project was to combine the information and functionalities of ARPA and ECDIS. By the incorporation of chart data, the system is able to compute track suggestions, taking account of the sea area in which the ships are sailing. In this process, the own ship’s safety requirements are inclu ded. Accordingly, the track thus determined can actually be sailed. By the overlaid display of radar picture and ECDIS, the situation involving encounters with other vessels can at all times be assessed within the over all context.

    Amann, Rupert P; Waberski, Dagmar

    2014-01-01

    Computer-assisted sperm analysis (CASA) systems have evolved over approximately 40 years, through advances in devices to capture the image from a microscope, huge increases in computational power concurrent with amazing reduction in size of computers, new computer languages, and updated/expanded software algorithms. Remarkably, basic concepts for identifying sperm and their motion patterns are little changed. Older and slower systems remain in use. Most major spermatology laboratories and semen processing facilities have a CASA system, but the extent of reliance thereon ranges widely. This review describes capabilities and limitations of present CASA technology used with boar, bull, and stallion sperm, followed by possible future developments. Each marketed system is different. Modern CASA systems can automatically view multiple fields in a shallow specimen chamber to capture strobe-like images of 500 to >2000 sperm, at 50 or 60 frames per second, in clear or complex extenders, and in marketing, and for the understanding of the diversity of sperm responses to changes in the microenvironment in research. The four take-home messages from this review are: (1) animal species, extender or medium, specimen chamber, intensity of illumination, imaging hardware and software, instrument settings, technician, etc., all affect accuracy and precision of output values; (2) semen production facilities probably do not need a substantially different CASA system whereas biology laboratories would benefit from systems capable of imaging and tracking sperm in deep chambers for a flexible period of time; (3) software should enable grouping of individual sperm based on one or more attributes so outputs reflect subpopulations or clusters of similar sperm with unique properties; means or medians for the total population are insufficient; and (4) a field-use, portable CASA system for measuring one motion and two or three morphology attributes of individual sperm is needed for field

    Full Text Available We describe a new Computer Assisted Diagnosis (CAD to automatically detect Alzheimer Patients (AD, Mild Cognitive Impairment (MCI and elderly Controls, based on the segmentation and classification of the Hippocampus (H and Corpus Calosum (CC from Magnetic Resonance Images (MRI. For the segmentation we used a new method based on a deformable model to extract the area wishes, and then we computed the geometric and texture features. For the classification we proposed a new supervised method. We evaluated the accuracy of our method in a group of 25 patients with AD (age±standard-deviation (SD =70±6 years, 25 patients with MCI (age±SD=65±8 years and 25 elderly healthy controls (age±SD=60±8 years. For the AD patients we found an accuracy of the classification of 92%, for the MCI we found 88% and for the elderly patients we found 96%. Overall, we found our method to be 92% accurate. Our method can be a useful tool for diagnosing Alzheimer’s Disease in any of these Steps.

    Gilleland, Cody L; Falls, Adam T; Noraky, James; Heiman, Maxwell G; Yanik, Mehmet F

    2015-09-01

    A major goal in the study of human diseases is to assign functions to genes or genetic variants. The model organism Caenorhabditis elegans provides a powerful tool because homologs of many human genes are identifiable, and large collections of genetic vectors and mutant strains are available. However, the delivery of such vector libraries into mutant strains remains a long-standing experimental bottleneck for phenotypic analysis. Here, we present a computer-assisted microinjection platform to streamline the production of transgenic C. elegans with multiple vectors for deep phenotyping. Briefly, animals are immobilized in a temperature-sensitive hydrogel using a standard multiwell platform. Microinjections are then performed under control of an automated microscope using precision robotics driven by customized computer vision algorithms. We demonstrate utility by phenotyping the morphology of 12 neuronal classes in six mutant backgrounds using combinations of neuron-type-specific fluorescent reporters. This technology can industrialize the assignment of in vivo gene function by enabling large-scale transgenic engineering.

  7. Computer-Assisted Inverse Design of Inorganic Electrides

    Directory of Open Access Journals (Sweden)

    Yunwei Zhang

    2017-02-01

    Full Text Available Electrides are intrinsic electron-rich materials enabling applications as excellent electron emitters, superior catalysts, and strong reducing agents. There are a number of organic electrides; however, their instability at room temperature and sensitivity to moisture are bottlenecks for their practical uses. Known inorganic electrides are rare, but they appear to have greater thermal stability at ambient conditions and are thus better characterized for application. Here, we develop a computer-assisted inverse-design method for searching for a large variety of inorganic electrides unbiased by any known electride structures. It uses the intrinsic property of interstitial electron localization of electrides as the global variable function for swarm intelligence structure searches. We construct two rules of thumb on the design of inorganic electrides pointing to electron-rich ionic systems and low electronegativity of the cationic elements involved. By screening 99 such binary compounds through large-scale computer simulations, we identify 24 stable and 65 metastable new inorganic electrides that show distinct three-, two-, and zero-dimensional conductive properties, among which 18 are existing compounds that have not been pointed to as electrides. Our work reveals the rich abundance of inorganic electrides by providing 33 hitherto unexpected structure prototypes of electrides, of which 19 are not in the known structure databases.

    A previous report described an online computer-assisted pathology encoding and reporting system (CAPER) developed at the Massachusetts General Hospital that accessions specimens, monitors their state of completion, produces all log books, and permits instantaneous display of all diagnoses rendered within a three-year period. The present report updates the functions currently available and describes a new function that enables the pathologist, independent of computer programmer support, to request complex, in-depth searches of the entire accumulated pathology data base, which at present contains in excess of 150,000 cases and 5,000,000 pieces of information. The pathologist can instruct the system to compare more than 30 types of data items through the development of Boolean expressions. The report also describes the test codes that were developed to reflect the work product of the surgical pathology division, form the basis for automated billing and compilation of monthly and yearly statistics, and are an integral part of the long-term data base for in-depth searches.

    2016-12-01

    Discrete-trial instruction (DTI) is a behavioral method of teaching young children with autism spectrum disorders (ASD) that has received a significant amount of research support. Because of a lack of qualified trainers in many areas of the world, researchers have recently begun to investigate alternative methods of training professionals to implement behavioral teaching procedures. One promising training method is interactive computer training, in which slides with recorded narration, video modeling, and embedded evaluation of content knowledge are used to teach a skill. In the present study, the effectiveness of interactive computer training developed by Pollard, Higbee, Akers, and Brodhead (2014), translated into Brazilian Portuguese, was evaluated with 4 university students (Study 1) and 4 special education teachers (Study 2). We evaluated the effectiveness of training on DTI skills during role-plays with research assistants (Study 1) and during DTI sessions with young children with ASD (Studies 1 and 2) using a multiple baseline design. All participants acquired DTI skills after interactive computer training, although 5 of 8 participants required some form of feedback to reach proficiency. Responding generalized to untaught teaching programs for all participants. We evaluated maintenance with the teachers in Study 2, and DTI skills were maintained with 3 of 4 participants.

    Smetana, Lara Kathleen; Bell, Randy L.

    2012-06-01

    Researchers have explored the effectiveness of computer simulations for supporting science teaching and learning during the past four decades. The purpose of this paper is to provide a comprehensive, critical review of the literature on the impact of computer simulations on science teaching and learning, with the goal of summarizing what is currently known and providing guidance for future research. We report on the outcomes of 61 empirical studies dealing with the efficacy of, and implications for, computer simulations in science instruction. The overall findings suggest that simulations can be as effective, and in many ways more effective, than traditional (i.e. lecture-based, textbook-based and/or physical hands-on) instructional practices in promoting science content knowledge, developing process skills, and facilitating conceptual change. As with any other educational tool, the effectiveness of computer simulations is dependent upon the ways in which they are used. Thus, we outline specific research-based guidelines for best practice. Computer simulations are most effective when they (a) are used as supplements; (b) incorporate high-quality support structures; (c) encourage student reflection; and (d) promote cognitive dissonance. Used appropriately, computer simulations involve students in inquiry-based, authentic science explorations. Additionally, as educational technologies continue to evolve, advantages such as flexibility, safety, and efficiency deserve attention.

    The synthesis of useful organic molecules via simple and cost-effective routes is a core challenge in organic chemistry. In industry or academia, organic chemists use their chemical intuition, technical expertise and published procedures to determine an optimal pathway. This approach, not only takes time and effort, but also is cost prohibitive. Many potential optimal routes scratched on paper fail to get experimentally tested. In addition, with new methods being discovered daily are often overlooked by established techniques. This thesis reports a computational technique that assist the discovery of economical synthetic routes to useful organic targets. Organic chemistry exists as a network where chemicals are connected by reactions, analogous to citied connected by roads in a geographic map. This network topology of organic reactions in the network of organic chemistry (NOC) allows the application of graph-theory to devise algorithms for synthetic optimization of organic targets. A computational approach comprised of customizable algorithms, pre-screening filters, and existing chemoinformatic techniques is capable of answering complex questions and perform mechanistic tasks desired by chemists such as optimization of organic syntheses. One-pot reactions are central to modern synthesis since they save resources and time by avoiding isolation, purification, characterization, and production of chemical waste after each synthetic step. Sometimes, such reactions are identified by chance or, more often, by careful inspection of individual steps that are to be wired together. Algorithms are used to discover one-pot reactions and validated experimentally. Which demonstrate that the computationally predicted sequences can indeed by carried out experimentally in good overall yields. The experimental examples are chosen to from small networks of reactions around useful chemicals such as quinoline scaffolds, quinoline-based inhibitors of phosphoinositide 3-kinase delta (PI3

    Teeth segmentation in computed tomography (CT) images is a major and challenging task for various computer assisted procedures. In this paper, we introduced a hybrid method for quantification of teeth in CT volumetric dataset inspired by our previous experiences and anatomical knowledge of teeth and jaws. In this regard, we propose a novel segmentation technique using an adaptive thresholding, morphological operations, panoramic re-sampling and variational level set algorithm. The proposed method consists of several steps as follows: first, we determine the operation region in CT slices. Second, the bony tissues are separated from other tissues by utilizing an adaptive thresholding technique based on the 3D pulses coupled neural networks (PCNN). Third, teeth tissue is classified from other bony tissues by employing panorex lines and anatomical knowledge of teeth in the jaws. In this case, the panorex lines are estimated using Otsu thresholding and mathematical morphology operators. Then, the proposed method is followed by calculating the orthogonal lines corresponding to panorex lines and panoramic re-sampling of the dataset. Separation of upper and lower jaws and initial segmentation of teeth are performed by employing the integral projections of the panoramic dataset. Based the above mentioned procedures an initial mask for each tooth is obtained. Finally, we utilize the initial mask of teeth and apply a variational level set to refine initial teeth boundaries to final contour. In the last step a surface rendering algorithm known as marching cubes (MC) is applied to volumetric visualization. The proposed algorithm was evaluated in the presence of 30 cases. Segmented images were compared with manually outlined contours. We compared the performance of segmentation method using ROC analysis of the thresholding, watershed and our previous works. The proposed method performed best. Also, our algorithm has the advantage of high speed compared to our previous works.

  2. Instruction-Level Characterization of Scientific Computing Applications Using Hardware Performance Counters

    Workload characterization has been proven an essential tool to architecture design and performance evaluation in both scientific and commercial computing areas. Traditional workload characterization techniques include FLOPS rate, cache miss ratios, CPI (cycles per instruction or IPC, instructions per cycle) etc. With the complexity of sophisticated modern superscalar microprocessors, these traditional characterization techniques are not powerful enough to pinpoint the performance bottleneck of an application on a specific microprocessor. They are also incapable of immediately demonstrating the potential performance benefit of any architectural or functional improvement in a new processor design. To solve these problems, many people rely on simulators, which have substantial constraints especially on large-scale scientific computing applications. This paper presents a new technique of characterizing applications at the instruction level using hardware performance counters. It has the advantage of collecting instruction-level characteristics in a few runs virtually without overhead or slowdown. A variety of instruction counts can be utilized to calculate some average abstract workload parameters corresponding to microprocessor pipelines or functional units. Based on the microprocessor architectural constraints and these calculated abstract parameters, the architectural performance bottleneck for a specific application can be estimated. In particular, the analysis results can provide some insight to the problem that only a small percentage of processor peak performance can be achieved even for many very cache-friendly codes. Meanwhile, the bottleneck estimation can provide suggestions about viable architectural/functional improvement for certain workloads. Eventually, these abstract parameters can lead to the creation of an analytical microprocessor pipeline model and memory hierarchy model.

    Full Text Available Objective. The purpose of this study was to evaluate whether elderly patients with vestibular dysfunction are able to preserve physical functional level, reduction in dizziness, and the patient’s quality of life when assistive computer technology is used in comparison with printed instructions. Materials and Methods. Single-blind, randomized, controlled follow-up study. Fifty-seven elderly patients with chronic dizziness were randomly assigned to a computer-assisted home exercise program or to home exercises as described in printed instructions and followed for tree month after discharge from an outpatient clinic. Results. Both groups had maintained their high functional levels three months after finishing the outpatient rehabilitation. No statistically significant difference was found in outcome scores between the two groups. In spite of moderate compliance levels, the patients maintained their high functional level indicating that the elderly should not necessarily exercise for the first three months after termination of the training in the outpatient clinic. Conclusion. Elderly vestibular dysfunction patients exercising at home seem to maintain their functional level, level of dizziness, and quality of life three months following discharge from hospital. In this specific setup, no greater effect was found by introducing a computer-assisted training program, when compared to standard home training guided by printed instructions. This trial is registered with NCT01344408.

    Full Text Available This research was carried out to determine the impact of computer-assisted teaching on teaching English. The first phase of the research was designed as an experiment and computer-assisted teaching and traditional teaching methods were conducted synchronically in two different groups. In the second phase, effects of variables such as gender, age, receiving private lesson and types of high schools of the students who attended the implementation were analysed. The sample of the research consisted of 40 first year undergraduate students from the first bachelor’s level program and another 40 from the second bachelor’s level program   in the Department of Computer Education and Instructional Technology in the Faculty of Education at Sakarya University in 2003-2004 academic year fall semester.  The students of the first bachelor’s level program were assigned to be the control group and the students of the second bachelor’s level program were assigned to be the experimental group. The experimental group was given the computer-assisted lessons for twelve weeks but traditional teaching methods were meanwhile used in the classes of the control group. The experimental group used a compact disc in the laboratory as an educational material, which was prepared by the researcher. Data for attitude evaluation were gathered by questionnaires and success was evaluated through students’ examination grades. In determining the success rate, pre-test and post-test grades were used as the data. At the end of the research, the results revealed that traditional teaching methods caused the students grouped according to the variables such as gender, age, private lessons and types of high schools to develop a negative attitude towards English lessons whereas computer-assisted teaching method led the students to develop a positive attitude. Although it was observed that traditional teaching methods made a positive impact on the success of the students in

    Full Text Available This paper illustrates the usefulness of natural language processing (NLP tools for computer assisted language learning (CALL through the presentation of three NLP tools integrated within a CALL software for French. These tools are (i a sentence structure viewer; (ii an error diagnosis system; and (iii a conjugation tool. The sentence structure viewer helps language learners grasp the structure of a sentence, by providing lexical and grammatical information. This information is derived from a deep syntactic analysis. Two different outputs are presented. The error diagnosis system is composed of a spell checker, a grammar checker, and a coherence checker. The spell checker makes use of alpha-codes, phonological reinterpretation, and some ad hoc rules to provide correction proposals. The grammar checker employs constraint relaxation and phonological reinterpretation as diagnosis techniques. The coherence checker compares the underlying "semantic" structures of a stored answer and of the learners' input to detect semantic discrepancies. The conjugation tool is a resource with enhanced capabilities when put on an electronic format, enabling searches from inflected and ambiguous verb forms.

    1984-08-01

    A computer-assisted education system for arrhythmia (CAESAR) was developed for students to acquire the ability to logically diagnose complicated arrhythmias. This system has a logical simulator of cardiac rhythm using a mathematical model of the impulse formation and conduction system of the heart. A simulated arrhythmia (ECG pattern) is given on a graphic display unit with simulated series of the action potential of five pacemaker centers and the "ladder diagram" of impulse formation and conduction, which show the mechanism of that arrhythmia. For the purpose of the evaluation of this system, 13 medical students were given two types of tests concerning arrhythmias before and after 2-hr learning with this system. The scores they obtained after learning increased significantly from 73.3 +/- 11.9 to 93.2 +/- 3.0 (P less than 0.001) in one test and from 47.2 +/- 17.9 to 64.9 +/- 19.6 (P less than 0.001) in another one. These results proved that this CAI system is useful and effective for training ECG interpretation of arrhythmias.
