Section II Project (Submission required)

Section II Project (Submission required)

Purpose of this project is to exercise the concepts learned in this chapter. It is not the purpose of this project to create realistic services and applications. We will create more realistic services and applications in the subsequent projects. In this project, you can use a console application or a simple GUI application to implement the user interface to your program. You do not need to create Web applications.

Description: Consider that you are creating an e-business: a book distribution system that involves bookstores and publishers. The system consists of multiple bookstores (clients) and multiple publishers (servers). The bookstores can buy in quantity of books from the publishers with lower prices. The required architecture and the major components of the system are shown in the diagram below.

 

 

 

 

In this project, you will implement both clients and servers in one system in multithreading. You will further implement such systems in distributed web client and server systems in the following projects.

An Operation Scenario of the book distribution system is outlined as follows:

(1) A Publisher uses a pricing model to calculate dynamically the book price for the bookstores. If the new price is lower than the previous price, it emits a (promotional) event and calls the event handlers in the bookstores that have subscribed to the event.

 

(2) A BookStore evaluates the price, generates an OrderObject (consisting of multiple values), and sends the order to the Encoder to convert the order object into a plain string.

 

(3) The Encoder converts the object into a string.

 

(4) The Encoder sends the encoded string back to the caller.

 

(5) The BookStore sends the encoded string to one of the free cells in the MultiCellBuffer.

 

(6) The Publisher receives the encoded string from the MultiCellBuffer and sends the string to the Decoder for decoding.

 

(7) The Decoder sends the OrderObject to the Publisher. The decoded object must contain the same values generated by the BookStore.

 

(8) The Publisher creates a new thread, an OrderProcessingThread, to process the order;

 

(9) The OrderProcessingThread processes the order, e.g., checks the credit card number and calculates the total amount.

 

(10) The OrderProcessingThread sends a confirmation to the bookstore and prints the order (on screen).

 

Note, the encoder and decoder here do not perform encryption and decryption tasks.

Components in the diagram are explained in details as follows, with their grading scores (points) allocation, Components 1, 2, 3, 4, and 5 belong to Assignment 3, and the rest of the components belong to Assignment 4. You will submit both assignments together as a project. We will enter the scores under assignments 1 and 2, for the purpose of score management.

 

Assignment 3 Tasks

  1. Publisher1 through PublisherK* are the objects of a class on the server side: Each object has a method to be started as a thread by the Main method and will perform a number of functions. It uses a PricingModel to determine the book prices. It defines a price-cut event that can emit an event and call the event handlers in the BookStore if there is a price-cut according to the PricingModel. It receives the orders (in a string) from the MultiCellBuffer. It calls the Decoder to convert the string into the order object. For each order, you must start a new thread (resulting in multiple threads for processing multiple orders) from OrderProcessing class (or method) to process the order based on the current price. There is a counter p in the Publisher. After p (e.g., p = 20) price cuts have been made, a Publisher thread will terminate. The bookstores do not have to make an order after each price cut. [15 points]

*Note 1: For the individual project, the number of publishers K = 1. For a group project (both two-member and three-member group), K = 2 if you have a 2-member team, and K = 3 if you have a 3-member team.

 

  1. PricingModel: It can be a class or a method in the Publisher class. It decides the price of books, which must be between 50 and 200. It can increase or decrease the price. You must define a mathematical model. The model can be a simple random function for individual projects. However, for the group projects, a more complex model must be developed, where the price must be a function with multiple parameters, such as the available number of the books and the number of orders received within a given time period. In other words, the function must take the amount of orders as input. You can use a hard-coded table of the prices, for example, in each weekday. You must make sure that your model will allow the price to go up some times and go down other times within your iterations of testing. [5 points]

 

  1. OrderProcessing is a class or a method in a class on the server’s side. Whenever an order needs to be processed, a new thread is instantiated from this class (or method) to process the order. It will check the validity of the credit card number. If you are doing an individual project or a two-member group project, you can define your credit card format, for example, the credit card number from the bookstores must be a number registered to the Publisher, or a number between two given numbers (e.g., between 5000 and 7000). For the three-member group project, a bank service must be created. Each OrderProcessing thread will calculate the total amount of charge, e.g., unitPrice*NoOfBooks + Tax + LocationCharge. For the group (two and three members) projects, a confirmation must be sent back to the bookstore when an order is completed. You can implement the confirmation in different ways. For example, you can use another buffer for the confirmation, where you can use a buffer cell for each thread, so that you do not have to consider the conflict among the threads. However, you still need to coordinate the write and read between the producer and the consumer. [10 points]

 

  1. BookStore1 through BookStoreN, You can set N = 5 in your implementation. Each bookstore is a thread instantiated from the same class (or the same method in a class). The bookstore’s actions are event-driven. Each bookstore contains a callback method (event handler) for the Publisher to call when a price-cut event occurs. The bookstore will calculate the number of books to order, for example, based on the need and the difference between the previous price and the current price. The thread will terminate after the Publisher thread has terminated. Each order is an OrderClass object. The object is sent to the Encoder for encoding. The encoded string is sent back to the bookstore. Then, the bookstore will send the order in string format to the MultiCellBuffer. For group project, before sending the order to the MultiCellBuffer, a time stamp must be saved. When the confirmation of order completion is received, the time of the order will be calculated and saved (or printed). [10 points]

 

The following components will be counted as assignment 3 tasks.

 

  1. OrderClass is a class that contains at least the following private data members:

 senderId: the identity of the sender, you can use thread name or thread id.

 cardNo: an integer that represents a credit card number.

 receiverID: the identity of the receiver, you can use thread name or a unique name defined for a publisher. If you are doing an individual project, you do not need this field.

 amount: an integer that represents the number of books to order.

 unit price: a double that represents the unit price of the book received from the publisher.

 

You must use public methods to set and get the private data members. You must decide if these methods need to be synchronized. The instances created from this class are of the OrderObject. [10 points]

 

Assignment 4 Tasks

 

  1. MultiCellBuffer class is used for the communication between the bookstores (clients) and the publishers (servers): This class has n data cells (for individual project, n = 2 and for group project, n = 3). The number of cells available must be less than (<) the max number of bookstores in your experiment. To write data into and to read data from one of the available cells, setOneCell and getOneCell methods can be defined. You must use a semaphore of value n to manage the availability of the cells. You must use an additional lock mechanism to provide read or write permissions for a cell. You cannot use a queue for the buffer, which is a different data structure. The semaphore allows a bookstore to see the availability of the cells, while the lock mechanism allows the agent to gain the right to write into one of the buffer cells. The Publisher can read buffer cells at the same time. Synchronization/monitor is required for read/write and write/write overlap. [20 points]

 

  1. Encoder is a class or a method in a class: The Encoder will convert an OrderObject into a string. You can choose any way to encode the values into a string, as long as you can decode the string back to the original order object. [10 points] Page 5 of 7

 

  1. Decoder is a class or a method in a class: The Decoder will convert the encoded string back into the OrderObject. Note: encoder and decoder here DO NOT perform encryption and decryption. [10 points]

 

  1. Bank service is a class. This question is for the three-member group projects only. It allows the bookstore to apply for a credit card number. The bookstore will use this number to purchase books from the publishers. The publishers will send the credit card number and the amount to the bank. The bank charges the account and returns the message “valid” if the account exists and the funds are sufficient for the purchase, otherwise, it returns “not valid”. When a publisher sends the credit card number and the amount to the bank, it will call the encryption service in the ASU repository to encrypt the credit card numbers in a string. If you use the .svc service, you must use “Add Service Reference”. If you use the .asmx service, you must use “Add Web Reference”. The recommendation is to use the .svc service, as it is the new standard. On the other hand, the bank will call the ASU decryption service to decrypt the number before comparing with the valid credit card numbers. The Bank class must also allow the account holder to deposit funds into the account. [20 points]

 

  1. Main: The Main thread will perform necessary preparation, create the buffer classes, instantiate the objects, create threads, and start threads. [10 points]

 

Additional Tasks for group projects

Two-member Teams: If you are doing the project as a group of two members, you are required to complete the following additional tasks:

[1] You must implement multiple suppliers (publishers) with K = 2. You must deal with all the issues that are incurred because of the increase in the number of suppliers.

[2] You must develop a more complex price model.

[3] The supplier must send a confirmation back to the bookstore when an order is completed.

[4] The buffer size (number of cells in the buffer) is 3, instead of 2.

In this option, one member must write the code of the bookstores and the main program. The other member must write the code of the supplier. The two members must jointly write the code for the buffer class.

 

Three-member Teams: If you are doing the project as a group of three members, you are required to complete all the additional tasks for the two-member group projects and the following additional tasks:

[1] You must implement multiple suppliers (publishers) with K = 3. You must deal with all the issues that are incurred because of the increase in the number of suppliers.

[5] If you have a three-member team, you must also define the bank service. The third member must implement the Bank class and share some other tasks in the assignment.

For three member team, there are totally 70 points in Assignment 4 of the project. The 70 points will be scaled to 50 points proportionally. For example, 70 à 50, 60 à 43, and 50 à 36.

 

Notes:

  1. It is the purpose of this course to enforce the knowledge of C# (Visual Studio), as we have multiple courses in our program that use Java. We encourage you to use C#. However, we allow the use of Java (on NetBeans) in this assignment. You must indicate the environment (e.g., VS 2015 or 2017 or NetBeans) that you use, so that the TA can use the same environment to grade the project. We taught multithreading in both Java and C#. However, we did not teach event-driven programming in Java. If you choose to do the project in Java, you need to study this part on your own. I suggest that you do the project in Java only if you already know how to program events. The event handling in Java is not as easy as in C# for this project, and you need to take extra effort to implement the required functions.

 

  1. You must follow what is defined in the assignment/project document. You have flexibility to choose your implementation details if they are not explicitly specified in the document. If you are not sure on any issue, ask the instructor or the TA by posting the question in the discussion board.
  2. The program and each component of the program must be well commented.
  3. You can choose to do this project as an individual project or a group project. I encourage you to do as a group project. Projects 3 and 5 will be required group projects and thus, you need to build a team anyway. The team building process is for assignments 3 and 5. The group used in assignment 2 does not have to be the same group for assignments 3 and 5. However, the group for assignment 3 and 5 must be the same, as the project in assignment 5 will be based on assignment 3.
  4. Project 3 will be partly a team project. If you have formed a team in this project, you can use the same team for the project 3. Of course, you can also use a different team for the project 3.

 

 

 

 

Submission Requirement

All submissions must be electronically submitted to the assignment folder where you downloaded the assignment paper. All files must be zipped into a single file.

Submission preparation notice: The assignment consists of multiple distributed projects and components. They may be stored in different locations on your computer when you create them. You must choose your own location to store the project when you create the project. Then, you can copy these projects into a single folder for the blackboard submission. To make sure that you have all the files included in the zip file and they work together, you must test them before submission. You must also download your own submission from the blackboard. Unzip the file on a different machine, and test your assignment and see if you can run the solution in a different machine, because the TA will test your application on a different machine.

If you submitted an empty project folder, or an incomplete project folder, we cannot grade your resubmission after the due date! We grade only what you submitted before the submission due date. Please read FAQ document in the course Web page for more details.

Grading of Programming Assignment/Project

The TA will grade your program following these steps:

(1) The TA will read your program and give points based on the points allocated to each component, the readability of your code (organization of the code and comments), logic, inclusion of the required functions, and correctness of the implementations of each function.

(2) Compile the code. If it does not compile, 40% of the points given in (1) will be deducted. For example, if you are given 20 points in step (1), your points will become 12 if the program fails to compile.(3) If the code passes the compilation, the TA will execute and test the code. If, for any reason, the program gives an incorrect output or crashes for any input, 20% of the points given in (1) will be deducted.

Please notice that the TA will not debug your program to figure out how big or how small the error is. You may lose 40% or 20% of your points for a small error such missing a comma or a space!

Late submission deduction policy:

 No penalty for late submissions that are received within 24 hours of the given due date;

 1% grade deduction for every hour after the first 24 hours of the grace period!

ABSTRACT

 

 Hypocalcemia is the most common complication after total thyroidecto­my. It is also the leading cause for prolonged hospitalization after thyroidectomy. The purpose of this study is to determine the validity of PTH monitoring six and twelve hours after total thyroidectomy in predicting hypocalcaemia. Nineteen patients who underwent total thyroidectomy alone or with neck dissection were included. PTH levels and calcium levels were monitored for all patients at two major points: at 6 and 12 hours post-operatively. In all patients, corrected calcium level was calculated.

At 6 hours post-operatively, 47% of patients had calculated calcium level< 8, with normal PTH level in 5 of them. At 12 hour post-operatively 37% of patients had calculated calcium level< 8, with normal PTH level in 3 of them. The validity of low serum PTH in predicting the post-operative hypocalcaemia and of normal serum PTH in predicting the normocalcemia were calculated.

 We conculude that there is a strong correlation of postoperative PTH with post thyroidectomy hypocalcaemia. A single serum PTH level 12 hours post-operatively is an accurate predictor of normocalcaemia. Patients with normal PTH and normal calcium level 12 hours postoperatively can be considered for discharge.

INTRODUCTION

Thyroid cancer is the most common endocrine malignancy accounting for approximately 1% of all human cancers and causing approximately 0.5% of all cancer deaths. Total thyroidectomy is the treatment of choice for clinically significant thyroid cancers. Transient hypocalcaemia after total thyroidectomy is reported at 20%-30% in most studies . The search for a blood test that identifies patients who will become hypocalcaemic after total thyroidectomy versus those who will remain normocalcaemic in the early postoperative period has evolved since the late 1980s (1-5) . Transient hypocalcaemia after total thyroidectomy is reported at 20-30% in most studies (2,7). Hypocalcaemia after total thyroidectomy is multi-factorial, but parathyroid dysfunction is the main cause.The incorporation of parathyroid hormone (PTH) levels as a monitor for hypoparathyroidism leading to hypocalcaemia has been the next step in the evolution of this field of research (2). Serum PTH has a half  life of 1 to 4 minutes. Any insult to parathyroid glands with impaired PTH secretion leads to an immediate decline in PTH levels.

Serum calcium homeostasis by PTH occurs through a variety of mechanisms:

  1. It promotes distal tubule calcium re-absorption.
  2. Bone re-absorption.
  3. 1,25(OH)2D mediated intestinal calcium absorption.

The nadir of serum calcium post total thyroidectomy is 24-48h postoperatively and it may be delayed as the 4th  postoperative day (6). Thus, monitoring calcium levels postoperatively, might lead to patients being hospitalized for longer time than otherwise necessary. The risk of hemorrhage and hematoma is mostly in the early postoperative  period, and warrant 24 h in hospital observation.

Inpatient stay beyond 24 h after Total thyroidectomy, in the absence of complications, is not warranted because patients suffer minimal pain (8).

Grodski found that postoperative PTH can be used to stratify the risk of patients developing    hypocalcaemia after thyroidectomy (1). In addition, the routine use of oral calcium supplements was shown to lead to decreased incidence and severity of post-thyroidectomy hypocalcaemia (1) .

In this work we aimed to investigate the role and best timing of PTH monitoring post total thyroidectomy in predicting hypocalcaemia.

 

MATERIALS AND METHODS

In this study we included patients (men and women) that underwent different thyroidectomy procedures: total thyroidectomy  or total thyroidectomy with central neck dissection. PTH levels were monitored for all patients at two major points: at 6 and 12 hours postoperatively. Calcium levels were measured twice a day. Corrected calcium level was calculated using the next formula:

Corrected Ca. = serum calcium + 0.8 (4 – serum albumin)

We defined two different points for hypocalcaemia:

While the corrected calcium level was less than 8 mg/dl

While the PTH level was less than 1.6 Pcmoll/l (8).

 

 

RESULTS

Nineteen patients were included (13 women and 6 men). Age of patients ranged from 20 to 76, with a mean age of 45 years. Patients underwent total thyroidectomy and 4 patients underwent total thyroidectomy with central neck dissection.

Mean time of hospitalization for these patients was 5.05 days (SD 0.97). The PTH levels, and corrected calcium levels (calculated) at three measurements are shown in Table I.

At 6 hours post-operatively, 47% (9 from 19) of patients had calculated calcium level< 8, with normal PTH level in 5 of them. At 12 hours post-operatively 37% (7 from 19) of patients had calculated.

calcium level< 8, with normal PTH level in 3 of them. At 48 h post-operatively, 2 of those 3 patients, had a normal calculated calcium level and were asymptomatic without calcium supplementation.

Seven of our patients (36.8%) received intravenous calcium treatment after the operation. Six of them received also the calcium supplementation. Five from these patients were symptomatic. Furthermore, one patient who underwent thyroidectomy with central neck dissection required 5 month calcium supplementation.

We calculated the validity of  low serum PTH in predicting the post-operative hypocalcaemia and of  normal serum PTH in predicting the normocalcaemia. For low serum PTH, the sensitivity of this test was 55% at 6 hours after the operation, and 71% at 12 hours after the operation. The specificity of this test was 90% at 6 hours after the operation, and 100% at 12 hours after the operation.

The sensitivity of normal serum PTH level as a predictor of normocalcaemia was 91% at 6 hours after the operation and 100% at 12 hours after the operation. The specificity of this test was 44% at 6 hours after the operation and 75 % at 12 hours after the operation.

 

 

DISCUSSION

Hypocalcemia is the most frequent complication of total thyroidectomy. The reported incidence in the literature varies from 1-50% (1). The risk of hypoparathyroidism increases in reoperative thyroid surgery and when central neck is associated (11). Patients symptoms and serum calcium levels dictate the necessity for calcium and vitamin D supplementation. The need of monitoring hypocalcemia is the leading reason for patients’ hospitalizaion beyond 23 hours (7) . Within the last decade, numerous studies have been conducted to predict the factors involved in the early prediction of hypocalcemia following thyroidectomy. Parathyroid hormone assay was one of the most reliable tool to predict postoperative hypocalcemia within hours of total thyroidectomy or completion thyroidectomy ( 11-13).

Several published reports have demonstrated the marked utility of the PTH assay in predicting patients who will develop hypocalcemia after thyroidectomy. However, there is a substantial

variability among these reports about the sensitivity and specificity  of PTH in accurately predicting hypocalcemia. Lam and ker found that all patients with PTH values less than 8pg/mL measured one hour after surgery became hypocalcemic, and all patients with PTH level greater than 9pg/mole did not (14) . Higgins and his colleagues demonstrated that 64% of those patients who subsequently required calcium supplementation had more than 75%  decrease in PTH levels from baseline 20minutes post surgery. Another finding was that most of patients who did not  need calcium supplementation (74%) had  a decrease of less than 75% from baseline (15). For Lombardi and colleague. PTH less than 10 pg/mL measured four or six hours after surgery predicted hypocalcemia with an overall accuracy of 98% (3). Pattou and colleagues  reported that a postoperative PTH level of 12 pg/mL or less was a good predictor of hypocalcemia, but did not state how long after surgery PTH values were obtained (6). Payne and his colleagues found that 6 hours post-operation PTH level is the most accurate predictor for hypocalcaemia and accurately predicts also the normocalcaemia (7).

As we saw earlier, most of the studies are discussing the correct timing of taking the measurements of PTH levels post-operatively. In our study we performed the measurements at 6 and 12 hours after the operation. We saw that the sensitivity of  low PTH as a predictor of hypocalcaemia was higher at the 12 hours measurement. Despite this no absolute PTH levels or percentage decline has 100% sensitivity or specificity. Sensitivity of normal PTH levels predicting normocalcaemia was higher than sensitivity of  low PTH levels predicting hypocalcaemia.

There are a few limitations to the study. First, it is a retrospective non-random review, which may result in selection bias. Secondly, a small number of participants. Further randomised controlled are required.

 

 

 

 

 

 

 

CONCLUSION

In our study we saw that a single serum PTH level 12 hours postoperatively is an accurate predictor of normocalcaemia. Thus, patients with normal PTH and normal calcium level 12 hours post-operatively can be considered for discharge reducing unnecessary hospitalization and patients’ discomfort.

Make sure you address each of these elements. If one of these elements does not apply to your article (rare), address that in your essay and explain how the article could have been improved by including it or how the author is justified in leaving it out.

Option B

Describe how each of the Eight Intellectual Standards (clarity, accuracy, precision, relevance, depth, breadth, logic, and fairness) were used or not used in the article, supported by an example. If one of these standards does not apply to your article (rare), address that in your essay and explain how the article could have been improved by including it or how the author is justified in leaving it out.

 

For either option you choose:

Write an introduction identifying the reasons for choosing either Option A or Option B and justify your reasoning.

In the conclusion of your essay, describe how you feel the article is biased.

Keep in mind, for either option you are being asked to analyze the article/author itself/himself/herself, NOT the topic discussed. Do not include your own opinion/position on the topic being addressed.

Social Influences Presentation

Influences from people’s social environments have an effect on their beliefs and behaviors, but they may not understand that influence. This assignment asks you to examine different social influences and the effects they may have on offender behavior.

Imagine your team has been asked to create a training on the role of social influences in offender rehabilitation for new support services staff. The intent of this training is to provide a base knowledge of this information so the new support services staff can structure their program delivery with these concepts in mind.

Develop examples of conformity, obedience, group membership, group conflict, and group decision making occurring in a group session for support services to help with offender rehabilitation.

Create a 10- to 12-slide Microsoft® PowerPoint® presentation to utilize in the training. Include the following:

  • Describe the concepts of conformity, obedience, group membership, group conflict, and group decision making.
  • Describe examples of these concepts occurring during support services.
  • Explain how the group influenced individual decision making in your examples.
  • Describe how social relationships developed or changed because of the group interactions in your examples
  • Explain how to navigate address these situations when they may occur.

Include a minimum of three sources.

Include detailed speaker notes for each slide. Do NOT repeat slide information in speaker notes, different with citations.

Format any citations in your presentation according to APA guidelines.

Submit your presentation to the Assignment Files tab.
