SISFISIO: A SOFTWARE FOR TEACHING AND LEARNING PHYSIOLOGY

The benefits of using interactive computer softwares in Education have been discussed for some time. This approach can improve cognitive capacity, better learning and, mainly, it makes information acquisition easier. This work presents the development of a software called SISFISIO. It is an “exercise and practice” system designed for teaching Physiology in biomedical courses. It was developed using the Delphi interface system and Macromedia Flash. The Flash components were integrated with Delphi using an ActiveX control. The internal structure of the software has two linearly-linked lists (a linked list is one of the fundamental data structures used in computer programming): one for the exercises and another for the question of each exercise. The information is stored in a text file that should be filled by the instructor. The SISFISIO software uploads this file and it fills the data structures cited above. Upon completion of a Physiology module, the student’s answers can be immediately verified, the scores tallied and the duration of the exercise measured. SISFISIO was incorporated into biomedicine classes at USS. The student’s evaluation, based on the 5-point Likert questionnaire and spontaneous comments, has indicated that the software has facilitated the learning of physiological concepts and was a very stimulating activity.

사출금형설계를 위한 웹기반 구배 검증 시스템

Injection-molded products serve a wide range of applications in our modern lives and their significance is ever increasing. However, difficulty of communication among related companies under the present system results in increase of lead time and decrease of production efficiency. The objective of this paper is the development of a web-based draft verification system in mold design processes. Although several commercial CAD systems offer draft verification functions, those systems are very expensive and inadequate to perform collaborative works. For collaborative work under the distributed environment, the proposed system uses native file transforming of CAD data into optimal format by using the ACIS kernel and InterOp. Functions of draft verification modules are constructed over the ActiveX control using the visual C++ and OpenGL. Therefore, collaborators related to the development of a new product are able to verify the draft and undercut over the Internet without commercial CAD systems. The system helps to reduce production cost, errors and lead-time to the market. Performance of the system is confirmed through various case studies.

Simulation system of arrhythmia using ActiveX control

A simulation system for arrhythmias has been developed using Windows-based software technology, ActiveX control. The cardiac module consists of six cells, the sinus, atrium, AV node, ventricle, and ectopic foci. The physiological properties of the cells, the automaticity and conduction delay, were modelled, respectively, by the phase response curve and the excitability recovery curve. Cell functions were implemented in the ActiveX control and incorporated into the cardiac module. The system draws the ECG sequence as a ladder diagram in real time. The system interactively shows diverse arrhythmias for various user settings of the cell function and bidirectional conduction between the cells. Users are able to experiment virtually by setting up a so-called electrophysiological stimulation. This system is useful for learning and for teaching the interaction between the cells and arrhythmias.

Development of component geographic information systems applying in forest resources management

The history, current situation, and development trend of GIS (Geographic Information System) applied in the forest resources management were discussed in this paper. On the basis of geographic spatial characteristics of forest resources data, a component geographic information system (ComGIS) was developed for forest resources management. The system embeds a GIS ActiveX control MapObjects (Inc. ESRI) on Visual C++ platform. System design, data organization and achieving way were studied and expatiated by taking Xigangzi Forestry Centre as study object. The system has many useful functions„ such as adding and display of various map layers, zoom of map by wheeling mouse, attribute and spatial data querying, map auto roaming, features rendering based on the spatial trait of data, label controlling through attribute data band with vector graph, as well as output of ‘Column chart’ for showing the result of statistics. At the same time, parts of source codes are attached.

Interactive Simulation System for Artificial Ventilation on the Internet: Virtual Ventilator

To develop an interactive simulation system "virtual ventilator" that demonstrates the dynamics of pressure and flow in the respiratory system under the combination of spontaneous breathing, ventilation modes, and ventilator options. The simulation system was designed to be used by unexperienced health care professionals as a self-training tool. The system consists of a simulation controller and three modules: respiratory, spontaneous breath, and ventilator. The respiratory module models the respiratory system by three resistances representing the main airway, the right and left lungs, and two compliances also representing the right and left lungs. The spontaneous breath module generates inspiratory negative pressure produced by a patient. The ventilator module generates driving force of pressure or flow according to the combination of the ventilation mode and options. These forces are given to the respiratory module through the simulation controller. The simulation system was developed using HTML, VBScript (3000 lines, 100 kB) and ActiveX control (120 kB), and runs on Internet Explorer (5.5 or higher). The spontaneous breath is defined by a frequency, amplitude and inspiratory patterns in the spontaneous breath module. The user can construct a ventilation mode by setting a control variable, phase variables (trigger, limit, and cycle), and options. Available ventilation modes are: controlled mechanical ventilation (CMV), continuous positive airway pressure, synchronized intermittent mandatory ventilation (SIMV), pressure support ventilation (PSV), SIMV + PSV, pressure-controlled ventilation (PCV), pressure-regulated volume control (PRVC), proportional assisted ventilation, mandatory minute ventilation (MMV), bilevel positive airway pressure (BiPAP). The simulation system demonstrates in a graph and animation the airway pressure, flow, and volume of the respiratory system during mechanical ventilation both with and without spontaneous breathing. We developed a web application that demonstrated the respiratory mechanics and the basic theory of ventilation mode.

A web-based tunneling-induced building/utility damage assessment system: TURISK

Abstract Prediction of ground movements and assessment of risk of damage to adjacent buildings/utilities have become an essential part of the planning, design, and construction of a tunneling project in urban environments. A web-based tunneling-induced building/utility damage assessment system, named TURISK, was developed. Currently available first order methods were implemented in TURISK for prediction of tunneling-induced ground movements and assessment of damage to adjacent buildings/utilities. TURISK was written in a server-client internet environment using the Microsoft Visual Basic 6.0 in conjunction with the MapGuide ActiveX Control software. The developed system was then implemented to the Daegu Metro Subway Line 2 construction site. The results demonstrated that the developed web-based building/utility assessment system can be used as an efficient tool in the perspective of tunneling-induced settlement risk management for tunneling projects in urban areas. Practical significance of tunneling-induced settlement risk assessment is also discussed.

A simple and sensitive method to measure timing accuracy.

Timing accuracy in presenting experimental stimuli (visual information on a PC or on a TV) and responding (keyboard presses and mouse signals) is of importance in several experimental paradigms. In this article, a simple system for measuring timing accuracy is described. The system uses two PCs (at least Pentium II, 200 MHz), a photocell, and an amplifier. No additional boards and timing hardware are needed. The first PC, a SlavePC, monitors the keyboard presses or mouse signals from the PC under test and uses a photocell that is placed in front of the screen to detect the appearance of visual stimuli on the display. The software consists of a small program running on the SlavePC. The SlavePC is connected through a serial line with a second PC. This MasterPC controls the SlavePC through an ActiveX control, which is used in a Visual Basic program. The accuracy of our system was investigated by using a similar setup of a SlavePC and a MasterPC to generate pulses and by using a pulse generator card. These tests revealed that our system has a 0.01-msec accuracy. As an illustration, the reaction time accuracy of INQUISIT for a few applications was tested using our system. It was found that in those applications that we investigated, INQUISIT measures reaction times from keyboard presses with millisecond accuracy.

A fuzzy logic based expert system for machinability data-on-demand on the Internet

Optimized machinability data is obtained from a skilled machine tool operator’s experience and intuition. Thus, fuzzy logic is a good approach to describe the strategy and action of the skilled operator when selecting the machinability data. In this paper, the development stages of an online fuzzy expert system (FES) are presented, possible methodologies are illustrated and their pros and cons are discussed in this paper. The FES has been developed using object oriented programing, dynamic link library (DLL) and ActiveX Control. It can be easily incorporated into the Internet and Intranet environment and can be accessed virtually at any place. A simplified fuzzy set-handling object has been developed in order to save resources. Weighted-centroid rather than union centroid is recommended in output defuzzification. Comparison between these two methods is made and discussed.

Multi-technology distributed objects and their integration

Research on software objects, components, middleware, and component-based applications concerns among others ActiveX controls, JavaBeans (JBs), the Microsoft Transaction Server (MTS), Enterprise JavaBeans (EJBs), and how they can interoperate with each other. Is their interoperation possible? Which elements are responsible for the software objects' incompatibility? Is compatibility a responsibility of the objects or of their underlying architectures? In this article, we discuss object compatibility problems by outlining three basic middleware remoting technologies: the OMG's Common Object Request Broker Architecture (CORBA), Microsoft's Distributed Component Object Model (DCOM), and Sun's Java Remote Method Invocation (RMI), discussing the basic incompatibility points, and overviewing the basic strategies for bridging the gap between CORBA, DCOM, and RMI.

Corrections to "Avoiding packaging mismatch with flexible packaging"

To integrate a software component into a system, it must interact properly with the system’s other components. Unfortunately, the decisions about how a component is to interact with other components are typically committed long before the moment of integration and are difficult to change. This paper introduces the Flexible Packaging method, which allows a component developer to defer some decisions about component interaction until system integration time. The method divides the component’s source into two pieces: the ware, which encapsulates the component’s functionality; and the packager, which encapsulates the details of interaction. Both the ware and the packager are independently reusable. A ware, as a reusable part, allows a given piece of functionality to be employed in systems in different architectural styles. A packager, as a reusable part, encapsulates conformance to a component standard, like an ActiveX control or an odbc database accessor. Because the packager’s source code is often formulaic, a tool is provided to generate the packager’s source from a highlevel description of the intended interaction, a description written in the architectural description language UniCon. The method and tools are evaluated with two case studies, an image viewer and a database updater.

An object oriented fully 3D tomography visual toolkit

In this paper we present a modern object oriented component object model (COMM) C + + toolkit dedicated to fully 3D cone-beam tomography. The toolkit allows the display and visual manipulation of analytical phantoms, projection sets and volumetric data through a standard Windows graphical user interface. Data input/output is performed using proprietary file formats but import/export of industry standard file formats, including raw binary, Windows bitmap and AVI, ACR/NEMA DICOMM 3 and NCSA HDF is available. At the time of writing built-in implemented data manipulators include a basic phantom ray-tracer and a Matrox Genesis frame grabbing facility. A COMM plug-in interface is provided for user-defined custom backprojector algorithms: a simple Feldkamp ActiveX control, including source code, is provided as an example; our fast Feldkamp plug-in is also available.
