Case: The Drop-In Visitor As the door closed behind her departing visitor, Jumanji Residential Supervisor Janet Mills glumly reflected that she had just lost an hour that she could ill afford to lose. She would either have to forego the schedule she was working on or be later for an upcoming meeting. The hour had been lost because of a visit from a pleasant but marginally aggressive sales representative trying to acquaint her with "the greatest little thing to come along". As was her practice, Janet consented to see the visitor although she resented the intrusion. This incident, occurring on a Friday, made Janet realize that she had lost time to four such drop-in visits this week alone. She did not like the idea of simply saying no or otherwise trying to avoid people who wanted to see her, but she was becoming more aware that her work was beginning to suffer because of such demands on her time. Questions: 1. Describe how stress can be both positive and negative.

Statement of the ProblemKuala Lumpur Hospital, as we all know, is one of Malaysia's busiest hospitals. This is due to the fact that it admits a diverse range of patients suffering from a diverse range of disorders. These patients have arrived as a result of the health sector that operates in this facility. In other words, the departments within it are quite diverse. As a result, the hospital must deal with a high volume of both existing and new patients. Employees are required to gather patient personal information such as name, address, and so on for all of these admissions. It intends to capture and save their data for further use. Employee admissions, such as physicians and nurses, should also be recorded by the hospital. Furthermore, the hospital must manually record the many departments, rooms, and physicians in hospitals. It is also required to keep frequent records of patients, patients admitted to the hospital, doctor exams on patients, patients who have had surgery, and…
