The purpose of this study was to evaluate the recovery process of categories on movement in daily living and quality of life of 81 patients after Total Hip Arthroplasty (THA). We investigated recovery process of discharge from K University Hospital on 11 categories on movement in daily living after 3 months, 6 months and 12 months from THA. We used Modified Arthritis Impact Measurement Scales for evaluation of quality of life.
The results were as follows : According to 11 categories on movement in daily living after THA, patients became mostly independent in a year. On the other hand, there were lower scores on the categories as getting on and off bus, squatting down, bowing as sitting, and cutting nails of toes independently.
The recovery process on 11 categories in a year after THA was classified into 4 groups. The conditions of recovery during three months after THA made significant differences.
The recovery process on categories on movement in daily living also made significant differences among different kinds of diseases. There were higher scores in osteoarthrosis (bilateral & unilateral), and lower scores in rheumatoid arthritis.
After THA compared with before THA, there were affirmative reactions on social roles, social activities, anxiety and depression, not only the improvements on pain, activity of daily living, physical activity and mobility. There was also a positive correlation among all variables.
There were significant differences between higher group of total scores about the categories on movement in daily living in 12 months after THA and younger group of age as the factor relating to quality of life. On the other hand, factors as the cases of rheumatoid arthritis were also affected.

Our study focused on the stress of inpatients in university hospitals. We researched the degrees of stress on 328 inpatients during hospitalization under 38 different situations that had been set to help bring out the causes of their stress.
The following four points were found
1) It turned out that inpatients' stress increases when they are :
　a) Anxious about whether their hospitalization causes some trouble to their families and friends.
　b) Anxious about whether their sickness is serious.
　c) Worring about the result of an operation or examination.
2) The study found out that the following eight factors out of 38 situations are the most crucial and important ones :
　1st factor : Insufficient information
　2st factor : Care and anxiety about their family
　3st factor : Physical and chemical environment
　4st factor : Relationship with other inpatients in the same room
　5st factor : Isolation from other persons
　6st factor : Anxiety about their economic situation
　7st factor : Dissatisfaction with the treatment by hospital staff
　8st factor : Insufficient access to fundamental habit
3) The multi-dimensional scaling method, used for a study on the relationship among the different situations, found that the situation can be roughly divided into two categories : situations that cause inpatients inner stress in relation to their own sickness ; and situations that are mainly connected with the demands of their daily lives.
4) There is a significant difference in stress according to the patient's sex, age and number of days in hospital, when the above eight factors are studied in connection with each patient's personal history and environment.
