twosemesters as evenly as possible so that students have the same amount of time to work onprojects each semester. Finally, projects for each theme must be developed.IntroductionThe Freshman Engineering Program (FEP) at the University of Arkansas (UofA) was establishedin 2007 with the primary objective of increasing the retention of new freshman in the College ofEngineering (CoE) to their sophomore year. This objective supports college-wide retention andgraduation rate goals. Thus far, there have been increases in both retention and graduation ratesas shown in Figure 1. Therefore, we believe we are providing our students with a solidfoundation for success in engineering study.A key component of the FEP is the Introduction to Engineering course

Additional objectives are typically included.Common objectives include teamwork, professionalism, decision making, and communication.Most capstone course structures make these objectives a natural part of the course [1-2]. Forinstance, communication, both written and oral is often an inherent aspect of the course.Programs may also include additional, non-traditional objectives to the course [3]. For instance,many capstone courses focus on interdisciplinary team aspects to help students adapt to workingwith colleagues from differing backgrounds. An intertwined aspect of capstone objectives is thesource from which the capstone projects are

continuous dialog amongst the students and theinstructor. Therefore, the development of NUVIEW was contingent on the creation of aplatform, which enables and encourages that interaction, regardless of locations for studentsand instructor. The authors decided this interaction would be best facilitated if all of thestudents and instructors were visible to each other at all times. And not only visible, but alsolife-size and positioned where visually it would appear as if everyone were in the same roomtogether. These concepts and conditions led to the development of the student sidewallprojection and the full size front wall projection of the professor (see Figure 1).Figure 1: NUVIEW Classroom SchematicThis paper will review the development of NUVIEW

Heated waterprovided to sinks and showers will aid the nurse in her educational efforts and help furtherreduce the incidence of sicknesses such as intestine infections and parasites.The DesignThe design was based on a goal of providing a five-minute shower at a flow rate of 1.85 gallonsper minute (7 L/min).
