Product Decisions Under Bottlenecked Operations
Youngstown Glass Company manufactures three types of safety plate glass: large, medium, and small. All three products have high demand. Thus, Youngstown Glass is able to sell all the safety glass that it can make. The production process includes an autoclave operation, which is a pressurized heat treatment. The autoclave is a A condition that occurs when product demand exceeds production capacity.production bottleneck. Total fixed costs are $200,000 for the company as a whole. In addition, the following information is available about the three products:
| Large | Medium | Small | ||||
| Unit selling price | $94 | $281 | $232 | |||
| Unit variable cost | 74 | 230 | 204 | |||
| Unit contribution margin | $ 20 | $ 51 | $ 28 | |||
| Autoclave hours per unit | 2 | 6 | 4 | |||
| Total process hours per unit | 6 | 12 | 8 | |||
| Budgeted units of production | 4,500 | 4,500 | 4,500 | |||
a. Determine the contribution margin by glass type and the total company income from operations for the budgeted units of production.
| Large | Medium | Small | Total | |
| Units produced | ||||
| Revenues | $ | $ | $ | $ |
| Variable costs | ||||
| Contribution margin | $ | $ | $ | $ |

b. Prepare an analysis showing which product is the most profitable per bottleneck hour. Round the "Unit contribution margin per production bottleneck hour" amounts to the nearest cent.
| Large | Medium | Small | |
| Contribution margin | $ | $ | $ |
| Autoclave hours per unit | |||
| Unit contribution margin per production bottleneck hour | $ | $ | $ |

A simple c program is needed to create encrypt and decode social security numbers. Then a validation must be used to make sure there are no invalid numbers.
**********************************************C PROGRAMMING*********************************************************************************
char social[][12] =
{"164-55-0726","948-44-1038","193-74-0274","458-57-2867","093-00-1093","159-56-9731","695-21-2340","753-66-
6482","852-73-4196","648-81-1456","879-61-1829","123-87-0000","000-65-3197","741-85-9632","963-25-7418"};
Create a function that will accept as input a properly formatted
social security number.
Then increment each digit by one. If the digit is "9" then make it
a "0". Return a properly formatted
social security number.
Then create a function that will do the opposite. This function
will take an encoded social security
number and convert it back into an unencrypted social security
number. The de-encoded number is
what this function will return.
Create a function to scan all of the patient's social security
numbers and detect if any of them are
invalid.
A Social Security Number (SSN) consists of nine digits, commonly
written as three fields separated by
hyphens: AAA-GG-SSSS. The first three-digit field is called the
"area number". The central, two-digit field
is called the "group number". The final, four-digit field is called
the "serial number". Any SSN conforming
to one of the following criteria is an invalid number:
Any field all zeroes (no field of zeroes is ever
assigned).
First three digits above 740
If you detect an invalid social security number, print the
patient's name, their social security number,
and then either "area number", "group number", or "serial number"
to indicate where the problem with
the social security number was detected.

Suppose I need to model a bank which provides loans to different companies. Further suppose that the only companies in my data model are those to whom I am providing loans or have provided loans in the past.
What is the appropriate minimum cardinality for the relationship between LOAN and COMPANY?
Suppose I need to model a credit card company where each customer can receive up to one credit card and each card can be sent to only one address.
What is the appropriate maximum cardinality for the relationship between CUSTOMER and CARD?
Suppose I need to model a university where students can, but do not have to, participate in extra-curricular activities. Each such activity can have zero or more participants.
What is the appropriate minimum cardinality for the relationship between STUDENT and ACTIVITY?
Suppose I need to model a university where students can have up to three majors (i.e., can be part of three departments).
What is the appropriate maximum cardinality for the relationship between STUDENT and DEPARTMENT?
Suppose I need to model a hardware store with varying inventory. That is, not all products will be sold at any given time.
What is the appropriate minimum cardinality for the relationship between STORE and PRODUCT?

Alex, 2-years old and the first child for parents Michael and Kim, was diagnosed with Cystic Fibrosis one year ago. The pediatric nurse practitioner recommended testing for Cystic Fibrosis after seeing Alex for his 9-month well-child check-up and discovering that he measured very low on growth and weight charts in comparison to other 9-month-old babies. Alex has had three respiratory infections in the last 6 months that have required hospitalization. You are the home care nurse that is assigned to develop a home care strategy for Alex and his family following discharge from his most recent hospitalization.
1. Thoroughly discuss community resources that are needed to promote health and minimize hospitalizations for Alex.
2. What Community resources are appropriate to the provided scenario above?
3. Thoroughly describe how members of the interprofessional team contribute to the management of chronic illness as well as Cystic Fibrosis
4. Clearly and thoroughly describes therapeutic communication strategies for all members of the interprofessional team
5. What Communication strategies are developmentally and age appropriate?

You are now working at a clinic and a patient walks in, telling you that they have Type 2 Diabetes. Checking their chart, you realize it’s been over three years since their hemoglobin A1C plasma levels have been tested. You run a quick lab analysis and see that they have a hemoglobin A1C plasma level of 11.5%. Given this information, answer the following questions.
(A) What is A1C and how is it different from regular blood glucose measurements?
(B) How is hemoglobin A1c is formed? What cell does this occur in?
(C) What is GLUT 1 and how does it contribute to hemoglobin A1c production? What kind of process is this and does it require energy? (hint: see Chapter 10, Lipids, Membranes and Cellular Transport)
(D) What does their level of 11.5% tell you about their disease state? How does this compare to the recommended A1C levels (both diabetics and non-diabetics)
(E) At their next visit you realize that your patient’s A1C levels have not changed. What products might be forming in their blood as a result of this, and what are some of the results of having an increase of these products in their body?

Background: Accounting scandals and fraud, both in the United States and internationally, have re-ignited the debate over the current laws, regulation and accounting principles. The relative merits of GAAP, which takes a “rules-based” approach to accounting, versus IFRS, which takes a “principles-based” approach have been under scrutiny. In the last couple of years, the FASB announced that it intends to introduce more principles-based standards to improve general accounting principles and practices.
Organizations have internal control measures to detect fraud. In additions, organizations are subjected to required reporting of financial information to external entities. With that in mind, answer the following items in your initial discussion response:
Make sure your initial response contains 175- to 265-words.
APA Formatting: Use citations where appropriate and list references.

George, Kim and Cindy all lost their jobs when the technology start-up they worked for was acquired by another company. After a few weeks of searching for another full-time job, George decided to get back to school to get an LPN certification. In order to finish as soon as possible, George chose not to work while finishing the certification. Kim took a part-time job in retail shortly after losing her job, but she continues to search diligently for full-time work. Cindy searched for a job for the first five weeks after being laid off, but as bills began piling up, she found herself moving into her parents’ basement. She recently gave up looking for work, because she figures that there just aren’t jobs available right now so there is no point looking.
a) Are George, Kim and Cindy unemployed, employed or not in the labor force?
b) Would any of the three be considered a discouraged worker? Which one?
c) How would each contribute to the unemployment rate? State whether u-rate increases, decreases or remains the same.
