Working as nurses, authors found that some patients were not content with their hospital life. Some patients wanted to move to another ward, and others complained about their ward atmosphere. In spite of patients' discomfort, nurses didn't know what made some patients complain about their ward. So, authors tried to find factors that influence atmosphere of hospital wards of the neurosurgery patients. To know the atmosphere of wards, authors selected five neurosurgery ward of a university hospital in Seoul. Observation took a month. An author observed using molar approach, in the morning, in the day time, and in evening time. Authors used concealment/no intervention technique. An author checked condition of people in the wards, and observed their verbal and nonverbal communication behavior, their activities and environmental characteristics, and interpreted their meaning through ethnographic research methodology by Spradly. Authors found there was an important factors that influence the atmosphere of ward. It was a human and his attitude. At least one person who was willing to help others made ward atmosphere better. Helping others physically whenever needed, supporting the depressed emotionally, offering foods, or talking to others friendly brought good atmosphere. On the contrary, if everyone was indiffernt to others, the atmosphere became cold. Self-centered or selfish behaviors such as occupying too much area, using the toilet too long, covering other's suction bottle without permission and seeing others deficate or urinate were hurtful. In addition to the attitude of patients and their families, unkindness of medical teams including nurses and doctors and tasteless meal caused bad ward atmosphere. Based on this research finding, authors suggest the followings. A. For the better atmosphere of ward 1. Nurses should try to make the ward atmosphere better by introducing new patient to older ones. 2. Every ward should have dividing curtains to keep patient's privacy. 3. All hospital personnel should be kind enough to make patients feel that they are repected. 4. Hospital should serve high quality meals to patients. 5. Patients had better stay with those in the similar condition. B. For the future studies 1. Repeated researches are necessary to check reliability of this results. 2. Researches for patients in different area such as ICU, or hemodialysis unit are necessary.
