Produced as part of RKO's This is America series (1942-1951), this film uses dramatic reenactment in telling the story of a young woman who becomes a nurse. The film opens with an account of the post-Second World War shortage of nursing staff. This is a preamble to a story of nurse training, exemplified by Betty Burns, one of the 43,000 women who enter nursing school that year. The film follows Betty from her first day at nursing school through her training in chemistry, anatomy, microbiology, nutrition, diet therapy, and pharmacy.

This training video employs a particular method to encourage nurse trainees to reflect on their responses to how patients and co-workers present themselves, verbally, physically, and emotionally. Based on psychologist Norman Kagan’s affect-stimulus technique, the camera takes the perspective of a trainee nurse who is presented with a series of different people who speak directly to the camera. The viewer is put into the situation of the trainee nurse, and is invited to respond to and reflect upon the different, sometimes difficult, interpersonal situations he or she encounters.

These reels show experiments in wound ballistics, with missiles fired into water, gelatin, mammals, frogs, and fish. Dr. Edmund Newton Harvey was best known for his research on bioluminescence, but he also conducted applied research in areas such as wound ballistics and aviation physiology. In these experiments, Harvey is investigating the large cone-shaped temporary cavity that results after a projectile passes through tissue or other substances. The temporary cavity is many times larger than the permanent cavity observed after the completed passage of the projectile.

Examines types of domestic flies, their habits, how they carry disease organisms, and methods of control through insecticides.

The purpose of this presentation is to describe and demonstrate the technique for achieving the maximum roentgenographic detail in mammography. This objective is achieved with the aid of a middle-aged female clinical subject, a female mammography technician, x-rays, photographs and graphs. The program stresses the importance of obtaining radiographic detail in the early detection of breast cancer. In this presentation statistics regarding the incidence of breast cancer in the United States are presented first.

This film shows, by means of cinefluorography and animation, the location of the esophagus and surrounding organs, various irregularities of the esophageal wall created by carcinomas, and the appearance of the area after radiation treatment.

This film is a trimmed version of a longer set of stitched-together reels that contain remarks by and interviews with National Institute of Mental Health scientist John B. Calhoun, as well as extensive footage of the thousands of mice Calhoun studied over many years. In Mouse City, Calhoun provided his research subjects food, water, bedding, protection from predators--all that they needed except adequate space. The results were destructive and dramatic.

The purpose of this presentation is to describe and demonstrate the characteristics of the cultured cells taken originally from a patient with cervical carcinoma. This objective is achieved with the aid of time lapse photography taken at various speeds. In this presentation the harvesting of the cells and the preparation of the culture are first described and demonstrated in a step-by-step fashion. The development of the freshly transferred culture is then demonstrated as itis photographed at one frame per minute.

This presentation describes the establishment and operation of an intensive care ward in a community hospital. The intensive care unit is discussed, initially, as part of a larger program of progressive patient care. This program groups patients according to their care needs and consists of six elements: intensive care, intermediate care, self care, long-term care, home care and outpatient care. The presentation discusses the steps involved in planning for the establishment of the intensive care unit.
