Computerized versus paper-and-pencil testing methods for a nursing certification examination: a review of the literature.

In conjunction with the decision of the Oncology Nursing Certification Corporation (ONCC) to computerize its examinations, the literature was reviewed to identify comparative studies of computerized versus paper-and-pencil testing methods and to determine the relative advantages of each. Data sources included journal articles and newsletter features identified via the ERIC, CINAHL, and PubMed databases or through frequent citation in the literature. The majority of studies found test scores to be independent of delivery mode. Several advantages of computerized testing were identified, including scheduling convenience, instant scoring capability, and enhanced security. One disadvantage may be an increase in testing anxiety for those without previous experience, although results in this area were mixed. Finally, studies and surveys often indicate an acceptance and preference for linear computer-based testing (CBT) by examinees.

[Current internet technology for gynecology--from hypertext transfer protocol to embedded web server].

The scientific and commercial use of the internet has caused a revolution in information technologies and has influenced medical communication and documentation. Web browsers are the becoming universal starting point for all kinds of client-server applications. Many commercial and medical systems--such as information reservation systems--are being shifted towards web-based systems. This paper describes new techniques. Security problems are the main topics for further developments in medical computing.

Untraceable partially blind signature based on DLOG problem.

This paper proposes a new untraceable Partially Blind Signature scheme which is a cross between the traditional signature scheme and the blind signature scheme. In this proposed scheme, the message M that the signer signed can be divided into two parts. The first part can be known to the signer (like that in the traditional signature scheme) while the other part cannot be known to the signer (like that in the blind signature scheme). After having signed M, the signer cannot determine if he has made the signature of M except through the part that he knows. We draw ideas from Brands' "Restricted Blind Signature" to solve the Untraceable Partially Blind Signature problem. Our scheme is a probabilistic signature scheme and the security of our Untraceable Partially Blind Signature scheme relies on the difficulty of computing discrete logarithm.
