Codes

Semantically conceptual units

1

Exerting coercion on timely replacement of light bulbs

I think the main reason why some facilities staff members do not come shortly to replace the burnt-out light bulbs is that it is not a priority. Sometimes, the manager quarrels with them, and then they replace the light bulbs with no delay. Force and coercion always work everywhere (laughing)

2

Ability to correctly recognize the color of objects under combined moonlight/sunlight light bulbs

Now, I am sitting under the moonlight light bulbs, and I see that the color of the closet is cream. If sunlight light bulbs are added, the color of this closet seems to be bright yellow. It means colors appear as they are in this way

3

Preference for spreading light everywhere due to increased mastery of work equipment

I like it when a uniform light covers everything, and it is not so concentrated. In this way, I am more in control of what I am doing for the patients

4

No use of dark colors as they induce misfortune

In my opinion, dark colors should not be used in hospitals. Such colors have always been implied as something bad is going to happen from the perspective of Iranian midwives

5

Tendency to install designs and panels on ceilings to avoid space occupation

If you ask me, it is more beautiful once the ceiling is patterned. There is no need to occupy the space of the walls, so the patients are distracted by it and look at the beauties above their head

6

Drowsiness at night due to sleep hormone release as a factor in error occurrence

Even if you sleep during the day, you still feel sleepy at night because sleep hormone release at night prevents you from being awake. How many days can you deal with the rhythm of your body? You cannot open your eyes and this leads you to commit errors

7

Satisfaction with windows and daylight and feeling better to keep the number of light bulbs lower

Daylight usually makes a person feel much better than artificial light. When many windows are installed to let daylight inside the hospital, the number of light bulbs is reduced during the day, and it would be considered as savings
