An introduction to current trends in the digital processing and manipulation of images is presented. The paper does not attempt a detailed survey of the field, but outlines instead the motivation behind it, and the relationships between the 'disciplines' such as image enhancement, pattern recognition and scene analysis involved with processing images. Selected examples are used to indicate the state of the art. Finally the typical configuration of an image processing system is described. The processing speeds of available digital processors are discussed, and the need for special purpose processors is emphasized. [ABSTRACT FROM AUTHOR]

SYNOPSIS What distinguishes man from all other primates is his archaic hair cover Nearly all the details that make his skin unique aie traceable to this single fact In vatious degrees,all nonhuman primates have a good pelage,which is characterized by some morphological and physiological similarities but often differs even between closely relatedspecies It can be thick or thin,short or long woolly or shaggy, dense oi sparse, and it assumes many varied colors All primates have dermitoglyphics on their faction surfaces they are also present on the volar surface of the tail of some New World monkeys ind on the knuckle pads of chimpanzees and gonllas The epidermis is uniformly thin and has little undersculpture Every species of primate has epideimal and dermal melinocytes which are often relatively distinct from all otheis Eccrine sweat glmds are found on the fnction surfaces of all species, but onlv the tiue piehensile tailed New World monkeys andOld World monkeys and apes have them also in the hairy skin Although chimpanzees and gorillas have more ercune than apocrine glands in their bodies, in neither do the sweat glands respond to heat stimulation as they do in man All primates havenumerous apocrine glands in the hany skin, but only man, the chimpanzee, and gorilla have an axillaiy organ The Oidei Primates is large and heteiogeneous most species have some common cutaneous featuies but the details in each are so distinct as to preclude generalizations [ABSTRACT FROM PUBLISHER]

The reflected light from a yarn squeezed flat shows its peak value when measured in a plane vertical to the twisted fibers. A twist irregularity tester based on this principle, which operates automatically and records the change of twist angle, was constructed. Several twist irregularity curves were obtained with both staple yarns and continuous filament yarns. Some factors affecting the accuracy of the test results were discussed, and the curve was compared with the twist angle measured by visual observation. [ABSTRACT FROM PUBLISHER]

This article explores the mental hygiene problems and programs related to service in the Armed Forces. Mental hygiene problems were presented by each volunteers or inductee in his efforts to make his own personal adjustment to the demands of service life. The problem of methods to be used in brief psychiatric examinations as the basis for eliminating such psychiatrically unfit as the feeble-minded, psychopathic, psychoneurotic, or psychotic was studied by both individual psychiatrists and by formal committees. Perhaps the hardest problem to be solved is the type of examination to be used, since group methods of personality study have not proved successful in civil life and there is at present no adequate group method available in the military.

This article focuses on the essential biochemical, anatomical, physiological and genetic factors producing the hair's defect. The regulation of the human hair cycle is one of the most mysterious biological events. Hair follicles develop in the 2nd-5th month of intra-uterine life. This first pelage is shed in 7th-8th foetal month. After birth no new hair follicles are formed unless as a response to severe trauma. The scalp hair grows for 1000 days, and will then rest for 100 days. However, the cycle can vary from 120 days to 7 years. There are 80-90 hairs in anagen to every 10-20 hairs in telogen.

The article presents a classified list of publications related to dermatology which appeared in various journals. Some of the publications in the list include, "Search for Twin Glands in the Skin," by R.I. Spearman, "Morbid Anatomy and the Skin," by R.W. Whimster, "Cutaneous Lipomas and Lipomatosis," by L.S. Osment, "Lymphangioma Causing Glaucoma and Requiring Surgery: A Five Year Follow-up," by H.L. Birge, "Lethal Complications of the Ehlers-Danlos Syndrome," by P. Beighton and "Genetic and Cytologic Methods of Investigation in Experimental and Clinical Dermatology," by G.B. Belenkey.

The article presents information on several published papers related to dermatology. Some of the papers are "Effects of Specific Prostaglandins on Development of Chick Embryo Skin and Down Feather Organ in Vitro," by C.W. Kischer, "Comparative Anatomy and Physiology of the Skin," by W. Montagna and "Gingival Fibromatosis Combined With Cherubism," by Y. Ramon, W. Berman and J.J. Bubis.

The subject categories are those in by Nathan W. Shock, published by Stanford University Press, Stanford, California (1951). Only major headings are used and the Roman numerals correspond to those given in the bibliography. In so far as possible, references are classified according to organ systems. Thus, most of the material on Geriatrics will be found under the organ system involved in the disease. Cross references are indicated by numbers at the end of each section. When available, abstract references are given (). Abbreviations for journals are those used in , 2nd Edition. For journals not listed, abbreviations were devised to the general rules used in the above source. It is impossible to cover all journals and list all papers concerned with aging and the aged. Authors and publishers are requested to call attention to publications or to send reprints to the Gerontology Research Center, Baltimore City Hospitals, Baltimore, Maryland 21224.

The Subject categories are those in A Classified Bibliography of Gerontology and Geriatrics by Nathan W. Shock, published by Stanford University Press, Stanford, California (1951). Only major headings are used and the Roman numerals correspond to those given in the bibliography. In so far as possible, references are classified according to organ systems. Thus, most of the material on Geriatrics will be found under the organ system involved in the disease. Cross references are indicated by number at the end of each section. When available, abstract references are given (B. A.—Biological Abstracts, P. A.—Psychological Abstracts, and P. I.—Population index). Abbreviations for journals are those used in A World List of Scientific Periodicals Published in the years 1900-1933, 2nd Edition. For journals not listed, abbreviations were devised to the general rules used in the above source. It is impossible to cover all journals and list all papers concerned with aging and the aged. Authors and publishers are requested to call attention to publications or to send reprints to the Gerontology Research Center, Baltimore City Hospitals, Baltimore 24, Maryland.
