An Image Encryption Algorithm Using Logistic Map with Plaintext-Related Parameter Values.

This paper deals with a plaintext-related image encryption algorithm that modifies the parameter values used by the logistic map according to plain image pixel intensities. The parameter values are altered in a row-wise manner, which enables the usage of the same procedure also during the decryption. Furthermore, the parameter modification technique takes into account knowledge about the logistic map, its fixed points and possible periodic cycles.

Ultrasound diagnosis of macrosomia.

Over the last two to three decades, there has been a 15-25 % increase in many countries in the number of women giving birth to large infant. Fetal macrosomia is associated with an increased risk of complications both for the mother and the newborn. In current obstetrics, the macrosomic fetus represents a frequent clinical challenge.

On the "proper use" of the Internet: self-help medical information and on-line health care.

Deliveries of medical information and assistance on the Internet are becoming increasingly popular, despite growing concern by some affected professional groups. "Self-help" efforts are abounding as individuals band together to support each other socially as well as gain political clout. The advent of widespread on-line health care is having a growing cultural impact, affecting the image of the practitioner-patient relationship and opening up the possibility of new roles for social workers and educators in the provision of health services.
