Analyses the system of work in the maintenance departments of 59 Saudi industries and services. The sample includes 13 manufacturing, 12 metals, nine chemical and 25 other industries and services. The data were collected by a specially designed survey. Results show that maintenance departments employ 26 per cent of the workforce. Only 11 per cent of the maintenance staff is Saudi. Most maintenance work (83 per cent) is done in‐house. Contracting‐out maintenance work is not yet a major activity. Generally, management is aware of what should be done but is shy of doing it. Managers are aware of standard times, preventive maintenance (PM), PM frequencies, etc. The system of work, however, reflects largely the manager′s personal style. Preparation of adequate reports on performance and cost is visibly lagging behind. Top management is supportive of maintenance department needs. Problems faced reflect preoccupation with spare parts acquisition and lack of qualified manpower rather than lack of funds or top management support.

Total quality management is now an established and widely used management process. One of its associated features is the application of statistical quality control techniques. These have been applied to both manufacturing and service industries. This paper presents an application of this methodology to the area of human performance evaluation in a service industry. It describes the data, method of their collection, their analysis, and a subjective evaluation criterion developed to evaluate the performance.

The purpose of this paper is to provide a comprehensive summary of the effect of different dietary approaches on polycystic ovary syndrome (PCOS).

This review represents the history of PCOS, the symptoms, diagnosis, and treatment. It also includes up‐to‐date research articles on different types of diets that have been shown some promising effects in the treatment of PCOS.

PCOS is nowadays considered the most common endocrine abnormality, with a range of 4‐12 per cent of women affected by the syndrome. It has been proven that diet, in addition to exercise and medication, plays an important role in the treatment of PCOS. The proper dietary approach for women with PCOS should focus on the PCOS symptoms and also improve weight loss, increase fertility, and decrease risks of cardiovascular diseases.

This paper provides accessible and comprehensive information on PCOS (since its discovery in 1935) to researchers, nutritionists, and women with PCOS who are interested in the effect of the diet on PCOS management.
