A new method for participatively developing and evaluating Man-Machine Interfaces (MMI) for Supervisory and Control Systems (S8ZC) of chemical distillation columns is presented. Participipation is considered important not only during the design phase, but should be built into the system by making the interface adaptable to the users requirements also during the operation phase. Better building blocks for input and output elements as well as improved models for navigation in picture hierarchies are offering enhaneed flexibility to the operator.

Background: Chronic rhinosinusitis (CRS) is a chronic inflammatory condition that affects the nose and sinuses. CRS is caused by a number of variables, including genetics, the state of the sinonasal microbiome, infections, and environmental factors. Aim of the study: To keep track of the results. of sinus surgery and to evaluate headache severity, duration, and frequency. Patients and Methods: A prospective study was conducted at Al-Azhar University Hospital. We targeted 60 Patients of both sexes between the ages of 18 and 65. Three groups were formed : Group (1): Chronic Rhinosinusitis with or without concha bullosa, Group (2): Chronic Rhinosinusitis with or without hypertrophy turbinate, and Group (3): Chronic Rhinosinusitis with or without deviated septum. Result: A total of 60 patients, significant difference found regarding nasal obstruction between the groups. Based on Visual Analogue Scale (VAS), the intensity of pain in the group1revealed a highreduction from 6.25 ± 1.87 (Preoperative) to 2.88 ± 1.01 (3 months aftertreatment) and 1.54 ± 1.21 (6 months following therapy ent). In group 2 the intensity of pain revealed a high reduction from 5.87 ± 0.911 (Preoperative) to 3.01 ± 1.39 (3 months following therapy) and 1.33 ± 0.935 (6 months following therapy). In group 3 The level of discomfort was shown to be significantly reduced from 6.48 ± 1.72 (Preoperative) to 2.51 ± 0.993 (3 months after treatment) and 1.59 ± 1.13 (6 months after treatment). Conclusion:The surgical removal of contact points in the nasal cavity can help with headache relief. The severity, duration, and frequency of contact point headaches are the highest. Chronic rhinosinusitis, rhinogenic headache, and sinus surgery are all terms used to describe chronic rhinosinusitis.
