this case study and question on it

Misr General Hospital has determined that its medication management
system is "broken". Costs are growing rapidly, doctors are complaining
that needed medicines are not available, while the pharmacy points
fingers at the internists saying that they use so many high price antibiotics
that they don't have the budget to buy other medications that are also
needed.
The recently instituted measurement of medication errors disclosed a
large number of them, a significant percentage of which has to do with
administration at the wrong time. Possibly related to the issue of
medication errors is the fact that post-hysterectomy infections have
increased greatly; the nurses in the operating suite claiming that patients
are not receiving their antibiotic prophylaxis properly. The quality
steering committee developed the following set of measure to determine
the extent of the problems and to help analyze their causes:
Internal Medicine:
Measure: The use of third generation cephalosporin as first line treatment
for the diagnosis of pneumonia.
Numerator: The number of patients over the age of eighteen who were
diagnosed on admission with pneumonia and received one of the
designated drugs within 24 hours of admission.
Denominator: All patients over the age of eighteen with the admission
diagnosis of pneumonia.
Frequency of measure: Monthly.

^{Obstetrics and Gynecology:}
Measure: Proper application of prophylactic antibiotics for abdominal
hysterectomy.
Numerator: All adult patients who received the first dose of antibiotics
within one hour of the start of the operative procedure of abdominal
hysterectomy.
Denominator: All adult patients who underwent the operation of
abdominal hysterectomy.
Frequency of measure: Every 3 months.

_{Nursing Service:}
Measure: Mis-timed administration of medications to patients.
Numerator: Medications administered within 30 minutes (plus or minus)
of the time ordered, or if the order is imprecise, such as 3 times a day,
within the time set by nursing policy.
Denominator: All medications ordered.
Frequency of measure: Sampling one day each week for each nursing
unit.

Pharmacy:
Measure: Frequency of medications ordered by physician not being
available for dispensing.
Numerator: Each instance of a medication ordered by a physician not
being in stock.
Denominator: None-measure is simple number.
Frequency: Monthly.

For each four measures, answer the following questions:
1. Do the numerator and denominator actually measure what is being
intended?
2. If not, why not?
3. Is the frequency of measurement appropriate?
4. If not appropriate, what is the proper frequency?
Do you have any other comment to make about any of the four measures?

QUESTIONS ABOUT MEDICATION ERRORS

A. If the prescription is wrongly written but the right dose is
administered at the right time, is it a medication error? If not, is it a
near miss?
B. If the order is wrongly transcribed, but the right dose is
administered at the right time, is it a medication error? If not, is it a
near miss?
C. If the order neglects to note that the patient is reported to be
allergic, is it a medication error? If not, is it a near miss?
D. If the order does not take drug-drug interactions into account, is it a
medication error? If not, is it a near miss?
E. If the prescription is correct, but the medication is administered to
the wrong patient, who does not suffer any ill effect, is it a
medication error? If not, is it a near miss?
F. If the patient's renal function necessitates a lower dose of
medication and this is not recognized, is it a medication error? If
not, is it a near miss?
G. If the usual adult dose is administered to an 85-year old patient
who suffers a well described dose-related adverse reaction, is it a
medication error? If not, is it a near miss?
H. A patient unexpectedly suffers a convulsion. He has received the
recommended dose of a drug that is contraindicated in the presence
of a seizure disorder, which he wasn't known to have. Was the
patient the victim of a medication error? If not, is it a near miss?
I. A diabetic patient has a renal arteriogram. Four days later, it is
noticed that her serum creatinine had increased three fold. She
received no medications known to cause kidney failure. Is it a
medication error? If not, is it a near miss?
J. A patient treated for pneumonia is found dead. He was last checked
three hours ago. The antibiotic he should have received two hours
ago was not given. Did he die as a result of a medication error?
K. If the answer to J is "no", was there a medication error? If not, is it
a near miss?

The following multipart problem asks you to derive a number of characteristics of an extrasolar planetary system. Assume that the planet has been detected by Kepler with the transit method, and that the transits are periodic (as shown below, a dip in the lightcurve indicates that a planet has moved in front of the star).

(a) The star has 3 times the mass of the sun (i.e., M∗ = 3.0M⊙) and the period of the transits are 2.0 Earth years (i.e, the orbital period of the planet around its star is twice the orbital period of the Earth around the sun Tp = 2.0T⊕). To make things interesting, let’s imagine that the planet is in an elliptical orbit with eccentricity e = 0.3. What is the perihelion of the extrasolar planet to it’s star in a.u.? (Remember that the radius of the Earth’s orbit around the sun is a⊕ = 1 a.u., it might help to eliminate some constants).

(b) If the star has its maximum emission (observed flux per unit wavelength interval) at a wavelength of λp,∗ = 250nm what is the temperature of the star T∗? (Hint: note that the sun has it’s peak emission λp,⊙ = 500nm and has a temperature of T⊙ = 5, 800K, use ratios!)

(c) If the star has twice the radius of the sun R∗ = 3.0R⊙, what is the luminosity of the star relative to that of the sun L∗/L⊙?

(d) Now, using the relative luminosity of the star to the sun, L∗/L⊙, from part (c), the relative distances of the Earth to the sun, d⊕, and the average distance of the planet to its star, dp calculate the no-greenhouse temperature of the planet as follows: First, assume that all of the properties of the atmosphere and the planet’s surface (i.e., the emissivity, absorptivity, pollution, etc.) are the same as those of the Earth. Also assume that the radius of the planet is equal to twice that of the Earth Rp = 2R⊙. Solve for the ratio of the temperature of the planet to that of the Earth (Tp = T⊙). Then, use the average temperature of the Earth T⊕ = 256K to find Tp. Do you want to live on this planet? (Note: the no- greenhouse temperature is that temperature for which the total power absorbed by the planet, equals the total power re-radiated into space assuming the planet is a perfect black-body)

Suppose that the sitting​ back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 23.4 in. and a standard deviation of sigma equals 1.1 in. These data are often used in the design of different​ seats, including aircraft​ seats, train​ seats, theater​ seats, and classroom seats. Instead of using 0.05 for identifying significant​ values, use the criteria that a value x is significantly high if​ P(x or ​greater)less than or equals0.01 and a value is significantly low if​ P(x or ​less)less than or equals0.01. Find the​ back-to-knee lengths separating significant values from those that are not significant. Using these​ criteria, is a​ back-to-knee length of 25.7 in. significantly​ high?

Think about industry‐disrupting companies such as Uber (disrupting the taxi industry) and Airbnb (disrupting the hotel industry). Research them if you don’t know much about them. What are the legal and ethical issues facing them? In what ways are they being responsible, irresponsible? How would you evaluate their corporate social responsibility?

The design should consist of two things:
(1) a list of every semaphore, its purpose, and its initial value, and
(2) pseudocode for each function. The pseudocode should be similar to the pseudocode shown in the textbook for the barbershop problem.
Every wait and signal call must be included in the pseudocode.    

Must use Java Threads and Java Semaphores (java.util.concurrent.Semaphore).
You may not use the “synchronized” keyword in Java for mutual exclusion.
You may not use Java data structures that have built-in mutual exclusion.

Please provide corresponding PSEUDOCODE along with JAVA CODE.

Hotel Simulation
A hotel is simulated by using threads and semaphores to model customer and employee behavior.
This project is similar to the “barbershop” example in the textbook. The following rules apply:

The hotel to be simulated has two employees at the front desk to register guests and two bellhops to handle guests’ bags.
A guest will first visit the front desk to get a room number. The front desk employee will find an available room and assign it to the guest.
If the guest has less than 3 bags, the guest proceeds directly to the room. Otherwise, the guest visits the bellhop to drop off the bags.
The guest will later meet the bellhop in the room to get the bags, at which time a tip is given.

Threads:

Guest:
1)   25 guests visit the hotel (1 thread per guest created at start of simulation).
2)   Each guest has a random number of bags (0-5).
3)   A guest must check in to the hotel at the front desk.
4)   Upon check in, a guest gets a room number from the front desk employee.
5)   A guest with more than 2 bags requires a bellhop.
6)   The guest enters the assigned room.
7)   Receives bags from bellhop and gives tip (if more than 2 bags).
8)   Retires for the evening.

Front Desk:
1)   Two employees at the front desk (1 thread each).
2)   Checks in a guest, finds available room, and gives room number to guest.

Bellhop:
1)   Two bellhops (1 thread each).
2)   Gets bags from guest.
3)   The same bellhop that took the bags delivers the bags to the guest after the guest is in the room.
4)   Accepts tip from guest.
 

Other rules:
1)   All mutual exclusion and coordination must be achieved with semaphores.
2)   A thread may not use sleeping as a means of coordination.
3)   Busy waiting (polling) is not allowed.
4)   Mutual exclusion should be kept to a minimum to allow the most concurrency.
5)   Each thread should print when it is created, and main should print when it joins the customer threads.
6)   Each thread should only print its own activities. The guest threads print guest actions and the employee threads print their own actions.
7)   Your output must include the same information, same wording, and the same set of steps as the sample output. Of course, each run can be different depending on the order of thread execution and the random assignments made.

Output

1)   Each step of each task of each thread should be printed to the screen with identifying numbers so it is clear which threads are involved.
2)   Thread output sample for 3 guests. The wording in your output should exactly match the sample.
