An investigation of vital issues that should be addressed to work on a country image
Authors: Chawuruka Patson , Phiri Maxwell Agabu
Published: November 2022

This paper sought to establish the vital issues that should be addressed to work on a national image. The country image is significant as it supports attracting foreign direct investment, tourists, foreign students, and expatriate workers who might bring managerial skills and technological exchange to the country. The paper tried to investigate how much political instability has impacted the national image, analyse the impact of policies on the country image and establish the effect of infrastructure on a country image, and contribute to the literature on the effect of the vital elements on the country image. The research contributes to the components of the national image. The country image is positively interrelated with a view on product integrity, pride of ownership, product gratification, enthusiasm to purchase from specific countries, and general product knowledge (Papadopoulos & Heslop, 2002). Nations historically branded themselves through icons. Symbols like flags, military uniforms, currencies, anthems, and ideology are due to regime changes and stereotypes (Fan, 2010; Dinnie, 2008; Fan, 2006). This research was based on a descriptive approach methodology, combining subjective and quantitative techniques. It was based on 100 stakeholders including politicians, media personnel, community development personnel, traditional leaders, church leaders, and academics and entrepreneurs. The study established that Zimbabwe’s image has been affected by political instability emanating from political activities, policy inconsistencies have affected inward investment in the country and the country’s infrastructure has an immense contribution to the national image. For the country to attract meaningful investment and foreign tourists it needs to deal with its image
Numerical simulation of film forming characteristics and mass transfer enhancement in horizontal polycondensation kettle
Authors: Chen Xupeng , Wu Jintao , Sun Jianfei , Yu Kunpeng , Yin Jian-Zhong
Published: November 2022

The process of producing high viscosity polyester by transesterification
polycondensation needs to adjust the operating conditions and equipment
structure of pre-polycondensation kettle and final polycondensation
kettle to realize process intensification. In view of this, the fluid
volume function (VOF) method of CFD was used to investigate the film
formation and surface renewal characteristics of horizontal
polycondensation kettle under different operating conditions, including
viscosity, rotating speed and liquid height. The results show that the
viscosity and rotating speed were positively correlated with the film
area and surface renewal in the pre-polycondensation stage. However,
increasing the viscosity by several orders of magnitude in the final
polycondensation kettle, the larger the film area and film thickness,
but the overall surface renewal of the disk decreased. Therefore, a
hexagonal hole disk is designed. It is found that the film is more
uniform and the power consumption can be reduced by more than 20 %.
Siponimod as a novel inhibitor of retinal angiogenesis: in vitro and in vivo evidence of therapeutic efficacy
Authors: Alshaikh Rasha , Zaki Rania , Din Rania Salah El , Ryan Katie , Waeber Christian
Published: November 2022

Background and Purpose: S1P receptors control endothelial cell
proliferation, migration, and survival. Evidence of the ability of S1P
receptor modulators to influence multiple endothelial cell functions
suggests their potential use for antiangiogenic effect. The main purpose
of our study was to investigate the potential of siponimod for the
inhibition of ocular angiogenesis in vitro and in vivo. Experimental
Approach: We investigated the effects of siponimod on the metabolic
activity (MTT assay), basal proliferation and growth factor induced
proliferation (BrdU assay), and migration (transwell migration assay) of
human umbilical vein endothelial cells (HUVEC) and retinal microvascular
endothelial cells (HRMEC). The effects of siponimod on HRMEC monolayer
integrity, and barrier function under basal conditions and TNF-α induced
disruption were assessed using the trans-endothelial electrical
resistance (TEER) and FITC-dextran permeability assays. Siponimod’s
effect on TNF-α induced claudin-5 distribution in HRMEC was investigated
using immunofluorescence. Finally, the effect of siponimod on ocular
neovascularization in vivo was assessed using suture-induced corneal
neovascularization in albino rabbits. Key Results: Siponimod did not
affect endothelial cell proliferation or metabolic activity, but
significantly inhibited endothelial cell migration, increased HRMEC
barrier integrity, and reduced TNF-α induced barrier disruption.
Siponimod also protected against TNF-α induced disruption of claudin-5
in HRMEC. These actions are mainly mediated by S1PR1 receptor
modulation. Finally, siponimod prevented the progression of
suture-induced corneal neovascularization in albino rabbits. Conclusion
and Implications: The effects of siponimod on various processes known to
be involved in angiogenesis support its therapeutic potential in
disorders associated with ocular neovascularization.

Published: November 2022

Commonly consumed vegetables and their surrounding soil samples are gathered
from a farm located in Klang, Selangor. Gamma spectrometry has been utilized
to analyze the activity concentration of the natural radionuclides, 226Ra,
232Th, and 40K in nine vegetables and soil samples collected. These data are
used to evaluate the hazard indices in the soil samples and their
radiological exposure to humans. It is found that the external hazard index
Hex ranged from 0.05 to 0.44 with a mean value of 0.14. The internal hazard
index Hin of the soil samples ranged from 0.05 to 0.56 with a mean value of
0.17. Both Hex and Hin average values are lower than the limit established by
the European Commission for Radiation Protection. The absorbed dose rate DN,
The annual ingestion dose Aeff, annual effective dose equivalent AEDE, and
excess life-time cancer risk, are used to learn the potential risk on the
general public consuming these vegetables. For the vegetable sample, it is
found that the average value for the DN is 6.70 nGyh?1 and ranged between
1.75 to 16.94 nGyh?1. The average value of Aeff is 10.17 mSv, and it ranges
from 2.54 mSv to 22.89 mSv. The range of AEDE is between 2.15 mSv and 20.78
mS, with an average value of 8.21 mSv. Excess life-time cancer risk ELCR is
used to determine the likelihood of cancer development due to the
radiological exposure of con suming these vegetables. It is found that the
average value of ELCR is 2.87?10?5, and the range is from 0.75?10?5 to
7.27?10?5. Both the Aeff and AEDE are found to be lower than the average
world value recommended by UNSCEAR.

Dealing with open sources of radioactive substances in nuclear medicine is a
daily task since contamination due to radioactive spills may happen
frequently. Proper and safe decontamination management is a vital
procedure. However, regular purchase of decontamination agents incurs high
costs and might be toxic due to their chemical properties. The purpose of
this study is to compare graphene oxide, which is an environmentally
friendly carbon-based material and marketable decontamination agent, in
decontaminating radioactive spillage. Samples of pure 99mTc and 131I from
the laboratory were spilled on a petri dish. The spill was immediately
decontaminated with a marketable decontamination agent swab and varying
concentrations of graphene oxide swab. The initial radioactivity of each
swab containing 99mTc and 131I was measured using a dose calibrator. The
absorbance spectra of each sample were analysed using an ultraviolet-visible
spectrophotometer. The morphology image of graphene oxide was observed under
field emission scanning electron microscope. For decontamination using a
marketable decontamination agent, the radioactivity of 131I was slightly
higher, whereas that of 99mTc was slightly lower than the high concentration
of graphene oxide. The absorbance spectra of 99mTc and 131I that had been
decontaminated using graphene oxide were observed at a range of 200 nm to
250 nm due ???* to the transition.

To reduce the risk of leaking confidential information in nuclear arms
control, we propose a new arms control inspection concept based on neutron
activation analysis, in conjunction with physical shielding technology to
distort the energy and propagation path of the outgoing particles in the
physical domain. The reliability and security of this authentication concept
are demonstrated using Monte Carlo simulations. It turns out that the
concept can readily identify isotope cheats and two typical geometric
cheats without revealing sensitive information about the inspected items.

Mathematical Modelling and Experimental Study of an Enhanced Double-Slope Glass Solar Still
Authors: Alswat Mohammed
Published: November 2022

Solar desalination is considered an important technology for solving the water shortage problem. In this research, a mathematical modeling and experimental study of an enhanced double-slope glass solar still were developed and evaluated based on a comparison with the conventional one. The two solar still were designed and fabricated at the Faculty of Engineering, University of Tabuk, and compared in the same operating climate conditions. The solar radiation model was developed, tested, and used with the solar still mathematical modeling to predict water productivity and daily efficiency. Copper T shape pieces were used in the solar still basin to increase the free water surface area inside the still at a water depth of 3 cm. The results indicated that the average measured and calculated values of accumulated productivity for conventional solar still were 3.01 and 3.32 L/m2.day respectively with a deviation of 9.3%. The corresponding average values for the enhanced solar still were 7.03 and 8.16 L/m2.day respectively. In addition, it can be noticed that the maximum measured daily thermal efficiency was about 56.4% and 25.31% for enhanced and conventional solar still respectively. Also, the cost evaluation was performed, and the results concluded that the enhanced double-slope glass solar still with cost per liter was about 0.0024 $/L/m2. The modeling and experimental results were compared based on the statistical evaluation methods and it is clear that the proposed mathematical model gives a good prediction of solar radiation and performance for the enhanced doubleslope glass solar still.

In the present investigation, the protector against sulfate corrosion of reinforcing steel AISI 1018, which provides the Eco-friendly Concrete system CPC-SCBA-SF, was evaluated. This system was made with CPC-SCBA-SF cementitious materials, in percentages of 90-5-5 and 80-10-10 respectively, with exposure of the concrete specimens to a 3.5% MgSO4 solution, an experimental arrangement that simulates the foundations of Civil Works such as bridges, buildings, pavements, etc.; in soils contaminated with sulfates. The design of the concrete mixtures was in accordance with the ACI 211.1 method. The behavior of the corrosion potential Ecorr and the corrosion rate (icorr) of the AISI 1018 steel embedded in Conventional Concrete (CC) and in the EC were evaluated during a period of 180 days of exposure to an aggressive environment. The Ecorr values indicate between a 10% risk of corrosion and uncertainty, according to the ASTM C-876-15 standard, but the icorr indicates a negligible level of corrosion but with a tendency towards the activation of the system, with the eco-friendly concrete EC-20 having the best performance.

Published: November 2022

We use recent explainable artificial intelligence (XAI) based on SHapley Additive exPlanations (SHAP), Local Interpretable Model-agnostic Explanations (LIME), and Light Gradient Boosting Machine (LightGBM) to analyze diverse physical agricultural (agri-) worker datasets. We have developed various promising body-sensing systems to enhance agri-technical advancement, training and worker development, and security. However, existing methods and systems are not sufficient for in-depth analysis of human motion. Thus, we have also developed wearable sensing systems (WS) that can capture real-time three-axis acceleration and angular velocity data related to agri-worker motion by analyzing human dynamics and statistics in different agri-fields, meadows, and gardens. After investigating the obtained time-series data using a novel program written in Python, we discuss our findings and recommendations with real agri-workers and managers. In this study, we use XAI and visualization to analyze diverse data of experienced and inexperienced agri-workers to develop an applied method for agri-directors to train agri-workers.
Contribution of Remote Sensing and GIS to the Inventory and Analysis of Factors influencing on the Development of Karst Features in the Middle Atlas, Morocco
Authors: Theilen-Willige Barbara , Naouadir Iliass
Published: November 2022

The development of karst features is a complex and interactive process of many factors with varying influence over time. The following main factors seem to have influenced the occurrence and development of karst features in the Middle Atlas in Morocco: Precipitations after extreme weather events depending on the precipitation pattern modified by orographic effects and exposition of the terrain towards the main rain-bearing clouds are determining surface water input and infiltration as well as the outline of morphologic watersheds and drainage basins. The lithologic conditions such as the outcrops of lower Jurassic limestones, the geomorphologic disposition, the volcanic activity within limestones combined with hydrothermal dissolution processes, and the structural conditions influencing water permeability in fault and fracture zones and, thus, the dissolution intensity, are further factors. Ongoing aseismic vertical and horizontal neotectonic movements due to plate tectonic activities and shallow earthquake activities are causing the development and reactivation of fault zones and as consequence modifying groundwater flow conditions in the karst hydrologic systems. Seismic activity can lead as well to the development of sinkholes and the collapse of caves. The development of a systematic Karst-Geo Information System (GIS) is recommended that should be updated regularly.

Studies on prediction recognize the presence of a large number of predictors of school-academic performance, as well as the existence of well-established predictors, nevertheless some psychoeducational variables remain little explored, even though their great potential. One of these is reflective thinking. The Laboratory for Research on Cognitive Architecture (LAICO) at the Federal University of Minas Gerais brought forth a contribution to reflective thinking. This is the development of the Interest Scale on Reflective Thinking which measures the interest of people in thinking reflectively. In this paper we present the Interest Scale on Reflective Thinking where it is shown in detail its structure and content. We also show evidence of structural validity, external validity and reliability of the scale.

This study aims to determine the resilience of single parent mothers in life. The study was conducted on 3 widows (1 divorce alive and 2 death divorced, aged 44-70 years) through observation and interviews with data reduction analysis, data presentation and conclusion. The results showed that the overall resilience of single parent mothers was low, seen from each aspect. However, DAS subjects have good resilience compared to RN and SW subjects, because DAS is elderly, single parent status is divorced, has long lost and is used to living alone. Meanwhile, the subjects RN and SW were single parents, divorced and felt traumatized when they got married. Based on the results of the study, especially for single mothers with new statuses and conditions, this is not a reason to give up facing a problem. The surrounding community is expected to pay more attention to the condition of single mothers, especially single mothers who have a level of economic difficulty and bear a lot of burdens. Not only that, counselors also have an important role in increasing single mother resilience so that the psychological impact of carrying out a new status as a single mother can be minimized.

Authors: Reist Alexandra M. , Reagan Jennifer K. , Fujita Shawna K. , Walny Alexis M.
Published: November 2022

OBJECTIVE

To describe the distribution of histopathologic diagnoses in a large population of dogs undergoing surgical treatment for spontaneous hemoperitoneum secondary to a ruptured liver mass. Additionally, to describe survival outcomes and assess for prognostic factors for overall survival time in this population.

ANIMALS

200 client-owned dogs with spontaneous hemoperitoneum resulting from a liver mass.

PROCEDURES

Medical records from 19 veterinary referral hospitals were reviewed. Data collected included signalment, clinical signs, blood work, radiographic and ultrasonographic findings, surgical methods, intraoperative and postoperative complications, outcomes, and histopathologic findings. Follow-up information was obtained by contacting the referring veterinarian or owner.

RESULTS

Well-differentiated hepatocellular carcinoma, benign masses, hemangiosarcoma, and other malignant tumors accounted for 36% (72/200), 27.5% (55/200), 25.5% (51/200), and 11% (22/200) of cases, respectively. Overall survival time for all dogs was 356 days and for the above categories was 897 days, 905 days, 45 days, and 109 days, respectively. Prognostic factors for survival included diagnosis, increased ALT, anemia, and whether a transfusion was received. Overall survival time in dogs with increased ALT was 644 versus 63 days with normal values.

CLINICAL RELEVANCE

The majority of dogs (63.5%) were diagnosed with well-differentiated hepatocellular carcinoma or a benign process, resulting in favorable long-term survival. The distribution of histopathology for ruptured liver masses resulting in hemoperitoneum has not been previously reported and may be useful for client discussions prior to surgery.

Published: November 2022

Introduction

Diabetic retinopathy (DR) is the leading cause of blindness in human and animal patients. Early detection and treatment of the disease are important and can be facilitated by proteomic approaches providing biomarkers.

Material and Methods

Tear films were collected on Schirmer strips from 32 canine patients (12 diabetic dogs without changes in the retina, 8 diabetic dogs with signs of DR, and 12 control dogs). Two-dimensional electrophoresis was used to separate tear film proteins prior to their identification with matrix-assisted laser desorption/ionisation–tandem time-of-flight mass spectrometry and interrogation of protein function databases to find matches.

Results

Five significantly differentially expressed proteins were identified; of those, one was downregulated (2ʹ-5ʹ-oligoadenylate synthase 3) and four were upregulated in the tear film of two diabetic groups (Ras-related protein RAB-13; aldo-keto-reductase family 1 member C3; 28S ribosomal protein S31, mitochondrial; and 60S ribosomal protein L5). The differentially expressed proteins identified in the tear film were involved in signalling pathways associated with impaired protein clearance, persistent inflammation and oxidative stress.

Conclusion

The results of our study confirm that the pathological process in the retina in the course of diabetes mellitus causes changes in the tear film proteome.
The Effectiveness of Total Physical Response Method in the Process of Learning and Teaching English Vocabulary to Pre-Adolescent Learners in an Online Teaching Setting
Authors: Husanović Damir
Published: November 2022

The acquisition of second language (L2) is a detailed and a time-consuming process. It is illustrated in the differences between spontaneous and studied capabilities, where the former describes the ability to acquire language naturally and subconsciously and the latter one allows students to organize their thoughts and apply conscious efforts of attention all while engaging in work, which cannot be performed automatically (Palmer, 1921:48). Lennenberg (1967: 176), in the argument, which referred to L2 learning, suggested that after puberty, the learning of L2 requires a labored effort and that foreign accents cannot be overcome easily, due to the inability to continue to spontaneously acquire foreign languages. This is known as the Critical Period Hypothesis, which states that if a child’s second language acquisition starts in the period between the ages of two and twelve it is possible to fully master the learning process with a positive outcome, while learners who embark on a learning process after this period will face obstacles and incompletion of the process of language learning (Abello-Contesse, 2006:13). Thus, the research focuses on young learners and their natural ability for a faster and efficient language acquisition. The primary concern of this research is the vocabulary acquisition of young, pre-adolescent, learners using TPR (Total Physical Response), in an online teaching setting. The research investigates whether pre-adolescent learners acquire vocabulary more naturally and effectively using TPR (thirty students as a part of the experimental group) than the learners who acquire vocabulary through a more traditional, Form-Meaning-Use (FMU), type of acquisition (thirty students as a part of the control group) in an online teaching setting. Moreover, the author explores the students’ ability to acquire a larger set of twelve vocabulary items within one 25-minute class and whether TPR is indeed effective in this process. If so, the researcher will potentially conduct a follow up research on this topic to see how strongly these vocabulary items could be retained in the students’ memory. This paper investigates the efficiency of TPR on students with kinesthetic, auditory, and visual learning preferences. The entire research is conducted in an online teaching setting.
Lessons Learned From Teaching System Thinking To Engineering Students
Authors: Azad Amin , Moore Emily
Published: November 2022

There are frequent calls for engineers to build integrated approaches to complex social and environmental problems. However, engineering education provides little opportunity to explore these "wicked problems".

Given the complexity of the challenges, engineers face upon graduation, introducing students to systems thinking approaches and wicked problems could greatly benefit their ability to deal with complex challenges in the real world. At the University of Toronto, we have been taking part in the initiative to design a course with the primary topic of Systems Thinking targeted towards upper-year students from all disciplines. The objective of this course is not for student teams to get to a solution, but more so to develop an understanding of the wicked problem they are working on while educating them to leverage system thinking tools for visualizing their problem space and system mapping techniques to look at open systems. 

This presentation will share our observations of the interactions, lessons learned, and challenges we faced during our first iteration of this course. The objective of this paper is to start an ongoing thread about the progress of teaching systems thinking concepts to engineering students throughout the upcoming years, along with the learning outcomes established from this course. In the future, we want to extract the data gathered from this course and research systems thinking principles and their benefits in approaching wicked problems.

This project is an immersive, multi-disciplinary engineering design activity with a focus on materials, solid mechanics, and instrumentation. The activity incorporates aspects of fundamental engineering theory, virtual predictive simulation, as well as physical testing and data collection. All of this was done in the context of a material selection and failure analysis of a piece of furniture (cantilever chair) which is a simplistic and recognizable device by the students.

The project focusses on structural analysis of the chair under a variety of loading conditions, coupled with a virtual simulation model using Finite Element Analysis (FEA). FEA is utilized to identify critical regions of the structure which are prone to failure. The complexity, constraints, and provided resources of the model varied, depending on the specific implementation of the course. Finally, a physical test apparatus was constructed and used to generate experimental responses that the students were able to use to calibrate their predictive model and theoretical hand calculations.

This activity was created initially for in-person instruction but was adapted for remote delivery during the pandemic. Both qualitative and quantitative data collected from 2nd year and graduate students indicated that the activity was effective in improving several forms of knowledge acquisition. This paper will discuss in detail how a common project platform was adapted for the two academic levels with evidence of its efficacy

In a rapidly changing world, Canadian Universities are preparing students by developing learner-centered experiential learning programs. Most of these programs within Engineering are mainly project-based courses to provide an opportunity for students to practice design-thinking process along with other technical skills. Engineering students are usually competent with the technical aspects of the design-thinking process, but they struggle to grasp the importance of the early steps that focus on understanding the challenge and generating ideas.

A team of educators have come together to create gamified experiences to guide students through idea generation process. This mini-project is part of a larger work that focuses on the design and the development of a multi-component online course to train students in creating new engineering design thinking mindset.

This paper that is a small piece of an on-going effort, focuses on the design and the test run of a gamified experience based on the concept of “what if?” question to help students to generate more ideas.
Using online to enhance student engagement of design reviews and lessons learned experiences
Authors: Harvel Glenn
Published: November 2022

This paper is about using the online environment to increase engagement in design and instilling a recognition of the importance of life long learning.  The work assesses changes in the delivery of a 4th year nuclear engineering design course and evaluates changes in the delivery of the course as it migrated from face to face to hybrid to online. In particular, the design review process was used to enhance engagement of the student body and a lessons learned exercise was used to enhance reflection on life long learning. The engagement is assessed in terms of class attendance, activity within the learning management system, and direct engagement in the design review process. The design review process requires each student to both present a design and to critique another group’s design. The design work is done as a team but the critique is done as an individual paralleling the industry process currently in use for the nuclear sector. In addition to the technical details, the performance of each student with respect to their soft skills is also assessed. This includes the number of students that actively engage or passively engage during both presentation and critique stages. Following the design review process, the students then engage in a lessons learned activity similar to what is done in the industry but simplified to focus on their experience. The activity also included an opportunity to reflect on themselves and establish a life long learning plan to address their personal findings. Note the paper will not discuss the personal findings specifically but instead will comment on the engagement of the students. Before using online approaches, the students fell into two distinct groups. One set was strongly active in the design review process and the other set was strongly resistive to participation and did the minimum necessary to get through the exercise. It was very clear that many students felt uncomfortable speaking openly in front of others. This changed significantly with the use of online technology. There was a significant increase in the number of students that engaged or at least felt comfortable to speak in the online setting. Some students displayed perhaps too much comfort in working from their personal environment space. This observation was also noted in the lessons learned exercise where the students went from saying the minimum necessary to having a large amount of insightful comments to make. The results suggest that allowing online participation in the experience has encouraged engagement of students that would resist a face to face experience.
Assessing Ethical Sensitivity Development in Undergraduate Engineering Students

Canadian engineers are expected to uphold high ethical standards as part of their responsibility to the profession and society. This expectation is echoed in the Canadian Engineering Accreditation Board (CEAB) graduate attributes and in the Ritual of the Calling of an Engineer [1], [2]. Part of upholding high ethical standards as an engineer involves the essential skill of being able to detect and identify ethical issues. This refers to one’s Ethical Sensitivity (ES), which is often overlooked in Engineering Ethics Education (EEE) currently. EEE in North America primarily focuses on the action plans and justifications developed to address presented ethical dilemmas, not on how to identify ethical dilemmas. This then leads to the question, are students’ ES skills being developed over the course of their undergraduate career? While there is some existing research on ethical decision-making and the factors that influence it, there is markedly less research on ES, less on ES assessment, and even less on ES assessment in engineering students. Additionally, the majority of ES assessment tools currently used are either not designed to specifically assess ES, are not designed for engineering, and/or cue the participant in some way to the ethical dilemmas presented, which could misrepresent the participant’s actual ES abilities.
This research will investigate current literature on ethical sensitivity and will also describe a research method to assess ES development in undergraduate engineering students. The focus of this paper will be on a pilot study currently in progress along with the next steps for this research. These results can provide insight to educators, ideally resulting in more effective teaching practices, and ultimately creating more ethically conscious engineering graduates.
Description of, and Outcomes from, a Novel First Year Engineering Design Course

In the Fall of 2021, the University of Saskatchewan’s College of Engineering implemented a new first year Engineering Design course called GE 142 (Design I).  In comparison to similar courses in other Engineering programs, the course was unique in a few respects.  First, it ran from mid-October to mid-December, and it included 7 lectures and 4 labs.  Second, it was focused almost entirely on problem definition.  Third, the assessment system was competency based.   Each of these elements made for a unique design course, and each element will be described in detail.

The course had a number of Learning Outcome goals in the general areas of knowledge, skills, experiences, and attitudes.  Knowledge was assessed using an automated adaptive quiz system employing Mobius™ software, linked to the Canvas™ Learning Management System (LMS).  Design skills were assessed through a series of six assignments that focused on the ability to characterize design problems, maintain an effective logbook, make a convincing case to undertake a design problem, communicate in a clear manner, and reflect on how to improve design practice.   Experiences included various types of design exercises conducted in lab settings.  For example, some design exercises were more open-ended while others were more closed design problems, and students also engaged in the characterization of a design problem with a live client.  Assessment of attitudes was carried out at the end of the course using a series of Likert-scale questions that probed students’ perspectives on the value of design, their enjoyment of design, the value of logbooks, their interest in tech innovation, and the importance of group dynamics, project management, and technical communication.

As a quality improvement/program assessment exercise, an analysis of grades and student attitudes was conducted and will be presented (n=306).  As well, an initial analysis of the performance of students on the Mobius questions was carried out.  In general, results were quite favourable both in terms of achievements against different types of Learning Outcomes and in terms of student attitudes towards various perspectives in Design.  Student responses for the attitude survey were anonymous and all grade and quiz analyses employed aggregate data.  At the end of the course, instructors reflected on what they felt should be continued, started, and stopped in subsequent iterations of the course.  The suitability of the student performance data against the Learning Outcomes will also be discussed in the context of accreditation criteria for the CEAB.
