Review the APA Code of Ethics. Consider the role of the Institutional Review Board (IRB). In 350-500 words, present ethical considerations that must be made to ensure your study adheres to the guidelines presented and is approved by an IRB. How will you ensure that participants in your study are protected from harm?Prepare this assignment according to the guidelines found in the APA Style GuideThe study I am proposing is whether food insecurities and related risk factors reasons for mothers to postpartum depression. Because postpartum depression is huge among most women after giving birth, a study will be conducted to determine what is the relationship between food insecurity and ppd. It is hard to predict which patient will devolp ppd but for a years time keeping numbers of all mothers that gave birth from two hospitals in different locations and questionnaires of their socioeconomic status and food security. Also nurses should recognize the signs and symptoms of ppd to be able to provide appropriate nursing interventions.

Submit each circuit file separately, with a meaningful name for each file! Do not Zip! 1. Consider the logic gate circuit shown below (5 points)  (2 points) Derive a Boolean equation for the output X. You don't need to simplify this equation, but feel free to try! (3 points) Draw a truth table for the circuit. 2. Introduction to Logisim (3 points)  This question will introduce you to Logisim – a graphical tool for designing and  simulating logic circuit/system Download the Logisim Software             Go http://www.cburch.com/logisim/download.html (Links to an external site.)             Download Logisim from SourceForge.net. Go Through the Logisim Tutorial Visit the Logisim tutorial at: http://www.cburch.com/logisim/docs/2.7/en/html/guide/tutorial/index.html (Links to an external site.) Go to Documentation, official 2.7x  Go to Beginner’s Tutorial Go through step 0: Orienting yourself Go through step 1: Adding Gates Go through step 2: Adding wires Go through step 3: Adding text Go through step 4: Testing your circuit. After finish all the steps, you should have a circuit file. Save the circuit file and submit it as an individual file! 3. (14 points) Design a combinational circuit system. Design a combinational circuit with three inputs x,y,z, and three outputs A,B,C. When the binary inputs is 0,1,2,or 3, the binary output is two greater than the input. When the binary input is 4,5,6,or 7, the binary output is one less than the input. Please answer all of the following sub-questions. 1) (3 points) x,y,z are inputs and A,B,C are outputs.Draw a truth table for the given function. 2) (3 points) Based on the truth table you draw, build Karnaugh maps for the output A,B,C. 3) (3 points) Derive (as simple as possible) Boolean equations for A,B,C using the Karnaugh maps 4) (3 points) Based on the Boolean equations, draw the logical gate diagram (circuit) for this system in Logisim. Save the circuit file and submit it as an individual file! 5) (2 points) Test your circuit with the Logisim simulation and generate the truth table (In logisim, project-->analyze circuit-->table). Copy & past the table in your submission! Note: Submit each circuit file separately, with a meaningful name for each file! Do not Zip!
