Integrated Development Environments (IDES) are presented as a unified set of information system development concepts, techniques, and computer-aided tools. An IDE consists of both a complete and unified development methodology and set of computer aids that support use of the methodology. The need for IDES and their characteristics are reviewed. The PLEXSYS-84 IDE is reviewed in relation to these needs and characteristics. Techniques and tools which extend the initial work are placed within the original PLEXSYS-84 framework and are described in some detail. [ABSTRACT FROM AUTHOR]

ABSTRACT: Diagnostic ultrasound of the pulse-echo imaging type is used in at least 25 per cent of pregnancies, and Doppler continuous wave ultrasound, as employed in external electronic fetal monitors, is used in nearly all pregnancies. Diagnostic ultrasound energy levels are from 0.1 to 40 mW/cm 2 . These intensity levels depend on the characteristics of the ultrasonic beam and temporal exposure. The American Institute of Ultrasound in Medicine states that…“there have been as of October, 1982 no independently confirmed significant biological effects in mammalian tissues exposed to intensities below 100 mW/cm 2 .” Some of the animal studies reviewed by the AIUM to reach this conclusion are discussed.

The author examines the value conflicts engendered by computing developments in two different institutional settings: electronic funds transfer systems and instructional computing in primary and secondary schools. While specific values depend upon culture and upon the character of the particular institutional setting studied, these two cases can serve as instructive points of departure for examining the value conflicts which generally accompany different modes of computerization in other developed and developing countries. In particular, computing developments in Brazil illustrate some of the parallels and contrasts between developed and developing countries.

Ninety-two strong-motion earthquake records from the California region, U.S.A., have been statistically studied using principal component analysis in terms of twelve important standardized strong-motion characteristics. The first two principal components account for about 57 per cent of the total variance. Based on these two components the earthquake records are classified into nine groups in a two-dimensional principal component plane. Also a unidimensional engineering rating scale is proposed. The procedure can be used as an objective approach for classifying and rating future earthquakes.

A prototype simulation software development environment (SSDE) has been developed at Texas A&M University as a means of providing a flexible system for the development of simulation software. It utilizes an underlying structure composed of a series of data bases and a language. This framework provides the means of hiding the file system, hiding the development support tools, and automating the transition between the different phases of development. The prototype SSDE includes several tools developed specifically to support simulation programming. This paper presents the rationale for software development environments and gives an overview of the prototype which has been constructed.
