Response time measurement of a Web system is critically important to evaluate its performance. This response time is one of the main barriers usually found in the implementation of an effective Electronic Health Records (EHRs) system. The database selected will affect the system performance. This paper presents a comparison of the response times of a EHRs Web system, TeleOftalWeb, using different databases. In order to calculate these times, M/M/1 queuing models is used. Four databases were selected: Oracle 10g, dbXML 2.0, Xindice 1.2, and eXist 1.1.1. The final objective of the comparison is choosing the database system resulting in the lowest response time to TeleOftalWeb.

Electronic Health

In Japan, electronic health record systems are gradually becoming popular at large hospitals, but are not yet frequently implemented in clinics. This is due to both prohibitive costs and a lack of interest in checking electronic health records on the part of patients. Doctors also may be opposed to showing patients their health records, as it then may require a doctor to let patients observe images to check for improvement of symptoms at follow-up. In this study, the authors developed a database system of dermatological images accessible to both doctors and patients. In this system, doctors can photograph affected skin areas and tag the images with keywords, such as patient ID or name, disease or diagnosis, symptoms, affected bodily regions, and free wards. The images and keyword tags are transmitted to a database housed on an Internet server. The authors implemented this system on a smartphone for quick and easy access during medical examination and on a tablet terminal for patients to use while waiting in the clinic. Using the tablet terminal, a doctor and patient may check for improvement of symptoms together.

Web Based System

This chapter describes a Web -based application to store and exchange Electronic Health Records (EHR) and medical images in Ophthalmology: TeleOftalWeb 3.2. The Web -based system has been built on Java Servlet and Java Server Pages (JSP) technologies. Its architecture is a typical three-layered with two databases. The user and authentication information is stored in a relational database: MySQL 5.0. The patient records and fundus images are achieved in an Extensible Markup Language (XML) native database: dbXML 2.0. The application uses XML-based technologies and Health Level Seven/Clinical Document Architecture (HL7/CDA) specifications. The EHR standardization is carried out. The main application object is the universal access to the diabetic patients EHR by physicians wherever they are.

Auditory Response

The purpose of this research work is to find out whether one of visual response time or auditory response time is faster than another on web based environment. Simple reaction time can be strong when an individual is asked to press a button as soon as a light or sound appears. A tool for capturing response times is created. This tool is a web application www.responsetime.muhammadsuhaib.com that runs on server and can be accessed through internet. R is commonly used in countless scientific disciplines for statistical analysis. Collected data will be analyzed by using R. it is concluded that on web based environment visual response times are not different than auditory response time. The data are also classified by gender to compare male response time and female response time, data analyzed based on gender, on visual stimuli, male react faster than female. However, on auditory stimuli, there is no different between male and female

Do So

Computer and Web-based interviewing tools have made response times ubiquitous in marketing research. Practitioners use these data as an indicator of data quality, and academics use them as an indicator of latent processes related to memory, attributes, and decision making. The authors investigate a Poisson race model with choice and response times as dependent variables. The model facilitates inference about respondents' preferences for choice alternatives, their diligence in providing responses, and the accessibility of attitudes and the speed of thinking. Thus, the model distinguishes between respondents who are quick to think and those who are quick to react but do so without much thought. Empirically, the authors find support for the endogenous nature of response times and demonstrate that models that treat response times as exogenous variables may result in misleading inferences.

The University

Health Level Seven (HL7) and Digital Imaging and Communications in Medicine (DICOM) standards are strongly influencing Electronic Health Records (EHRs) standardization. In this chapter, we present a web-based application, TeleOftalWeb 3.2, to store and exchange EHRs in ophthalmology by using HL7 Clinical Document Architecture (CDA) and DICOM standards. EHRs are stored in the native Extensible Markup Language (XML) database, dbXML 2.0. Application architecture is triple-layered with two database servers (MySQL 5.0 and dbXML) and one application server (Tomcat 5.5.9). Physicians can access and retrieve patient medical information and all types of medical images through web browsers. For security, all data transmissions are carried over encrypted Internet connections such as the Secure Sockets Layer (SSL) and Hypertext Transfer Protocol over SSL (HTTPS). The application verifies the standards related to privacy and confidentiality. The application is being tested by physicians from the University Institute of Applied Ophthalmobiology (IOBA), Spain.
