Nowadays, as the increasing functionality and scales of embedded systems, system design grows more complex than before. So verification and simulation of systems become an important facet in hardware-software co-design issues. But it is almost impossible to simulate an embedded system without real hardware implementation or environment communication, especially for control-dominated reactive systems. Therefore, in this paper, we will introduce a GUI environment module generator for integrated Esterel\C++ simulation. By generating the GUI modeling environment, we can simulate and verify the whole embedded system conveniently.

Nowadays major shipbuilding companies are trying to expand their business not only to shipbuilding but to offshore projects as well. DSME is one of them. DSME is trying to set up a flexible design and construction environment for shipbuilding and offshore construction in a single shipyard. The shipbuilding and offshore projects, however, have their unique technology but they need to be designed and constructed in one site. To support this new requirement, DSME has developed an integrated CAD system for ship and offshore projects. In this integrated design environment, the designers can design commercial ships and offshore projects in a flexible manner. Concurrent design is very important for ship and offshore design. As compared to the complexity of the product, the design period is quite short. In effect, the design system for the ship and offshore project has to support concurrent design. One essential point of concurrent design environment is a product model based design system. DSME has developed and implemented the 3D product model concurrent design environment based on Tribon M3. Tribon is a widely used CAD system in shipbuilding area that is developed by Tribon Solutions. DSME has both customized the Tribon system and developed in-house application systems to support its own design and production procedures. All the design objects are modeled in one common database to support concurrent design and accurate production. The major in-house development focused on the modeling automation and automatic drawing generation. During the drawing generation process many of the additional production information are also extracted from the 3D product model. In addition, several applications and functionalities have been developed to apply the shipbuilding based Tribon M3 system to offshore projects. The development of shape nesting, tubular connection, isometric drawing, grating nesting systems are the typical.

We present an experimental implementation of the inexpensive microwave security sensor that can detect both static and slowly moving objects in cluttered environment. The prototype consists of a frequency-modulated continuous wave radar sensor, control board or computer and software. The prototype was tested in a cluttered indoor environment. In case of intrusion or change of environment the sensor will give an alarm, determine the location of new object, change in its location and can detect a slowly moving target. To make a low-cost unit we use commercially available automotive radar and own signal processing techniques for object detection and tracking. The intruder detection is based on a comparison between current 'image' in memory and 'no-intrusion' reference image. The main challenge is to develop a reliable technique for detection of a relatively low-magnitude object signals hidden in multipath clutter echo signals. Various experimental measurements and computations have shown the feasibility and performance of the system.

The emergence of smartphones is creating a faster and easier digital communication society along with the existing Internet. Among the various methods of communication, the smart notification is most often used in early childhood education institutions for information exchange between parents, teachers and directors. And the notification helps parents understand the development status and curriculum of infants more easily. Therefore, this paper developed an integrated infant management system based on a web-based platform and a mobile app platform for exchanging various information on infants management between directors, teachers and parents. Through the established system, the director, teachers, and parents can check the information they need at any time, and it is possible to provide a mobile service environment where multiple guardians can safely take care of one infant. In addition, multiple guardians can provide appropriate feedback information through the collection and analysis of various data by using the infant and toddler integrated management system. In the future, if the functions provided based on the smartphone app are configured according to the user, it is expected that it will be able to expand from daycare centers to educational institutions.

For CALS environment, sharing information among business processes within the enterprise and between enterprises have been increased through common database. To support integrated data environment, data of the local legacy system must coincide with data of the global system to guarantee data integrity and transparency. This study is concerned with the implementation of this distributed database system under CALS environment. Based on existing IDEF methods, we developed a modified method which newly includes concepts of the enterprise structure, the integration of legacy databases, the distribution of data, and the distributed applications .

This paper is aimed at the development of comprehensive environmental management system, which can be operated on the basis of world wide web. This study has been initiated as a topic of G7 project in 1988, and will be accomplished in 2001. Even thought there should be lots of works remaining to achieve this goal, preliminary products can be summarized as follows : 1) integrated environments information management system, 2) web based control engine, 3) surface water environment management system, 4) subsurface water environment management system, 5) sewer and waterworks management system. The core methodology of the engine is the generalized multidimensional finite element matrices to depict the terms in the analysis of various partial differential equations. Spatial information management system (ArcView) and Visual Basic were extensively employed to construct GUI oriented web based engine. Developed systems were consist with very intense computer codes due to the necessity of combinatory management of environmental problems. The web based engine could be served as a decision tool for the integrated management of environmental projects in Korea.
