Today, many companies have to deal with problems in maintaining legacy database applications, which were developed on old database technology. These applications are getting harder and harder to maintain. Reengineering is an important means to address the problems and to upgrade the applications to newer technology (Hainaut, Englebert, Henrard, Hick, J.-M., & Roland, 1995). However, much of the design of legacy databases including data dependencies is buried in the transactions, which update the databases. They are not explicitly stated anywhere else. The recovery of data dependencies designed from transactions is essential to both the reengineering of database applications and frequently encountered maintenance tasks. Without an automated approach, the recovery is difficult and time-consuming. This issue is important in data mining, which entails mining the relationships between data from program source codes. However, until recently, no such approach was proposed in the literature.

With the development of computer technology and network communication technology and multimedia technology,database technology has become an important technical means and software technology for organizing and managinglarge amount of data in information society. It is the foundation of network information management system. Itnot only has a complete theoretical basis, and with the rapid development of hardware technology and softwaretechnology, its application is more and more widely. However, the rapid development of information technology isthat people face such a situation: CAD / CAM, CIMS, CASE, GIS and other applications require the managementof increasingly complex information, such as multimedia data, such as multimedia data, spatial data, scientifi c data,Data and other data types, these data compared with the traditional type, not only the type of complex, diverse forms,and storage, transmission, operation and retrieval methods also have many new features, new requirements, on theone hand, the need for database technology and database systems To manage these complex data in order to obtainthe database system has many of the data management functions, such as query, retrieval, recovery, concurrencycontrol, integrity, storage management. On the other hand, due to the vigorous development of network technology,information processing has long been from a single user environment to the development of the network environment,this environment for resources, information sharing provides a great convenience, and because of multi-machine worktogether to greatly improve the work , The combination of the two requires that the database management system beable to manage complex data objects in a networked environment or heterogeneous environment. Traditional DBMSscannot eff ectively handle complex multimedia data, thus requiring the use of new multimedia indexing and retrievaltechniques. Multimedia database technology is an important part of computer technology, it can simultaneously acquire,process, edit, store and display text, sound, video, graphics and other diff erent media, while it has diversity, integrationand interactivity and so on. Only to solve the key technical issues of multimedia, can be widely used to promote itsfaster development.

Developement of computer technology provides much improvements on electron microscopy, such as simulation of images, reconstruction of images and automatic controll of microscopes (auto-focussing and auto-correction of astigmatism) and design of electron microscope lenses by using a finite element method (FEM). In this investigation, procedures for simulating the optical properties of objective lenses of HREM and the characteristics of the new lens for HREM at 200 kV are described.The process for designing the objective lens is divided into three stages. Stage 1 is the process for estimating the optical properties of the lens. Firstly, calculation by FEM is made for simulating the axial magnetic field distributions Bzc of the lens. Secondly, electron ray trajectory is numerically calculated by using Bzc. And lastly, using Bzc and ray trajectory, spherical and chromatic aberration coefficients Cs and Cc are numerically calculated. Above calculations are repeated by changing the shape of lens until! to find an optimum aberration coefficients.

This study investigated factors that influence public school speech-language pathologists' acceptance and/or resistance to computer technology. Significant differences were found between speech-language pathologists who are frequent users of computers in the workplace and those who seldom or never use them. These differences were attributed to differences in attitudes toward computers, available funding for computers, in-service training, and physical facilities.

Situational Test

Advances in computer technology have created opportunities for the development of a multimedia situational test in which responses are filmed with a webcam. This paper examined the relationship of a so-called webcam test with personality, cognitive ability, job experience, and academic performance. Data were collected among 153 psychology students. In line with our expectations, scores on the webcam test, intended to measure interpersonally oriented leadership, were related to extraversion, conscientiousness, emotional stability, and job experience. Furthermore, the webcam tests significantly predicted students’ learning activities during group meetings over and above a cognitive ability test and a personality questionnaire. Overall, this study demonstrates that webcam tests can be a valid complement to traditional predictors in selection contexts.
