Machine Shop Learning Kits

Currently in the Cal Poly Machine shops, students are struggling to find ways to fulfill the 10 hours of shop experience required to gain their Yellow Tag certification. Red Tag is the first level of certification students generally achieve their freshman year. It allows them to use basic machine tools such as drills, shears, benders, etc. Then after completing 10 hours of shop experience they can take the Yellow Tag test, which gains them access to use a welder, mill, and lathe. The heads of the machine shop, the shop technicians, and the mechanical engineering students will all have different but mutually beneficial advantages from these kits. Currently, the students ask shop technicians for ideas, and the employees of the shop then give them a stack of project folders on file. These folders contain photos of various wood and metal projects with limited instructions, and can be confusing for a student with no previous shop experience. Students currently have problems because these folders contain limited instructions, and so they are unable to immediately know the correct process to start making the project. Another problem associated with this current solution, is that many students are unable to acquire the proper materials due to lack of transportation or lack of knowledge about which materials they would need. Many students start college without shop or machinery experience, and so entering the machine shops can be intimidating. The managers of the Hangar and Mustang 60 would like to decrease any confusion with a set of kits containing basic and detailed instructions. These projects would ideally be creative and interesting projects students would enjoy making, and in the process learn how to use the various machinery available in both shops. Originally we assumed these students had never used a tool before. We then surveyed around 300 mechanical engineering students to gauge a more accurate depiction of average skill level. We will be designing these kits around the data found in our survey as discussed later in this report. These kits would be available and useful to all students attending Cal Poly who wish to increase their tool and manufacturing knowledge. Our goal, by the end of three quarters, is to create kits for mechanical engineering students to earn hours working in the shop and to become familiarized with the tools and resources there. We will have four kits designed for students with their Red Tag certification, which allows them to use wood tools and general sheet metal work. In addition we will have one kit for students who have their yellow tag, and wish to learn how to use the welders, mills, and lathes. This will give us a final count of 5 projects. Our overall objective is to create projects that contribute to furthering a student’s machining education, and give them first-hand experience with the tools in Mustang 60 and the Hangar. By the end we will deliver a total of five kits containing detailed instructions for kit assembly and product assembly. The different kits will require a variety of experience and certification, more specifically four red tag kits and 1 advanced yellow tag kit

Go Skate!: The Physiological Responses and Perception of Training on Inline Skates

It is unclear how inline skate training affects the performance and enjoyment of other modes of exercises. PURPOSE: The purpose of this study is to determine if inline skating is an effective and enjoyable alternative method of exercise when compared to running and using the elliptical. METHODS: Each participant\u27s functional movement, body composition, and efficiency in running, skating, and using the elliptical was assessed before and after the skate training program at 80% of each participant\u27s age-predicted heart rate. The skate training program consisted of three 45-minute training sessions for 6 weeks. After all training and testing was completed each participant was given a questionnaire regarding their perceptions of enjoyment and preferred method of exercise. A repeated measures ANOVA in IBM SPSS was used to analyze the differences between pre- and post-tests on exercise efficiency, body composition, and functional movement. RESULTS: While there were no significant differences in weight or resting heart rate, there was a significant change in blood pressure, body fat percentage and lean mass. There were also significant improvements in the elliptical average heart rate, the skate VO2 and the distance traveled during skating. In addition, there was significant improvement in the FMS trunk stability push-up. All of the subjects considered participating in inline skating in the future. CONCLUSION: Inline skating is an enjoyable method of exercise that also provides an effective workout that carries over to other forms of exercise, and improves core strength.https://engagedscholarship.csuohio.edu/u_poster_2017/1001/thumbnail.jp

Cardiorespiratory Responses and Gender Differences Between Exercising on the Simply Fit Board and the Ab Rocket Twister

One of the biggest problems in fitness is finding a workout method that is effective yet enjoyable. PURPOSE: The purpose of this study is to compare the Simply Fit Board and Ab Rocket Twister across genders and ultimately to determine which product is more enjoyable. METHODS: Heart rate, Rate of Perceived Exertion, ventilation, oxygen consumption, and total kilocalories were all measured on 21 males and 20 females while using the Simply Fit Board and Ab Rocket Twister for 10 minutes at 75% of their age predicted maximal heart rates. At post-testing, each subject completed the Perception of Exercise Experience questionnaire. A repeated measures ANOVA in IMB SPSS was used to analyze the cardiorespiratory responses and their differences across gender. RESULTS: Between the two products there was a significant difference (p \u3c 0.05) between all of the test variables except VO2 and total kilocalories. The results across gender also showed that there were significant differences in VO2 and total kilocalories. The post-test questionnaire showed that the Simply Fit Board was more enjoyable than the Ab Rocket Twister. CONCLUSION: The data collected displayed that the subjects preferred the Simply Fit Board over the Ab Rocket Twister; however, both products burned the same amount of calories.https://engagedscholarship.csuohio.edu/u_poster_2017/1002/thumbnail.jp

An Investigation into the Effectiveness of Brief Guided Meditation

Meditation has many benefits for reducing stress and anxiety, by inducing a relaxation response. It is unclear how guided meditation compares to other forms of relaxation. PURPOSE: The purpose of this study is to determine if a guided meditation mp3 is as effective as other methods of relaxation. METHODS: Skin conductance and breaths per minute were measured on 30 male and female adults while reading, meditating, and watching a video, each on three different occasions. Prior to the study each participant rated their psychological state of being using questionnaire styled scales. A repeated measures ANOVA and a related measure nonparametric test in IMB SPSS were used to analyze the physiological and psychological responses across subjects. RESULTS: There was a significant difference (p \u3c 0.05) between the book and meditation in GSR and respiration rate. A significant difference (p \u3c 0.05) was found between the book and video in physiological state and in respiration rate. There was also a significant difference (p \u3c 0.05) between the meditation and video in physiological state, GSR, and respiration rate. The DASS and Freiburg Mindfulness Inventory tests showed that the anxiety, stress, and depression rates of each participant did not affect the testing modalities.https://engagedscholarship.csuohio.edu/u_poster_2017/1000/thumbnail.jp

What’s your Snapscore? Correlations to Personality, Narcissism, and Anxiety

Snapchat is a popular social media network, but considerably less researched than other more established platforms. The purpose of this study was to examine how the amount of Snapchat use is correlated to personality, narcissism, and anxiety. We hypothesized there would be positive correlations between Snapchat usage and narcissism, extroversion, and anxiety. Using data from a convenience sample of participants recruited from Amazon Mechanical Turk, Pearson’s correlations and t-test analysis provided insight on these connections. There were significant positive correlations between Snapchat usage and narcissism, anxiety, and extraversion, but t-test analyses revealed that the users with low Snapscores had higher narcissism, anxiety, and extraversion

Clinical outcomes at 12 months and risk of inflammatory bowel disease in patients with an intermediate raised fecal calprotectin : a ‘real-world’ view

Objectives: A recent systematic review confirmed the usefulness of fecal calprotectin (FC) in distinguishing organic (inflammatory bowel disease (IBD)) from non-organic gastrointestinal disease (irritable bowel syndrome (IBS)). FC levels 92% to exclude organic gastrointestinal (GI) disease. Levels >250 μg/g correlate with endoscopic IBD disease activity; sensitivity 90%. We aimed to determine clinical outcomes in intermediate raised FC results (50–250 μg/g). Setting: Primary care general practices in Coventry and Warwickshire, and 3 secondary care hospitals. Participants: 443 FC results in adults (>16 years old) were reviewed from July 2012 to October 2013. Clinical data was collected from hospital databases and general practitioners. Long-term clinical data was available in 41 patients (out of 48). Primary and secondary outcome measures: The number of new diagnoses of IBD, IBS and other diagnoses for the intermediate group. The number referred and discharged from secondary care. Results: A new IBD diagnosis was made in 19% (n=8) of intermediate results (1% of normal and 38% of raised results). 5% (n=2) of intermediate results had known IBD in remission. A new IBS diagnosis was made in 27% (n=11) of intermediate results, while 34% (n=14) remained undiagnosed, although 8 of these were not referred to secondary care. Conclusions: FC testing remains useful in aiding diagnosis of organic GI conditions. However, unlike negative and strongly positive FC results, intermediate FC results lead to a mixture of diagnoses. The OR of a new diagnosis of IBD for an intermediate result compared to normal FC result was 26.6, while an intermediate FC result gave an OR of 0.54 for a new IBS diagnosis compared to normal FC. For intermediate FC results, 1 in 3 patients remained in secondary care after 12 months with an OR of 3.6 compared to a normal FC result

Kinetic Study of DNA Topoisomerases by Supercoiling-Dependent Fluorescence Quenching

DNA topoisomerases are essential enzymes for all living organisms and important targets for anticancer drugs and antibiotics. Although DNA topoisomerases have been studied extensively, steady-state kinetics has not been systematically investigated because of the lack of an appropriate assay. Previously, we demonstrated that newly synthesized, fluorescently labeled plasmids pAB1_FL905 and pAB1_FL924 can be used to study DNA topoisomerase-catalyzed reactions by fluorescence resonance energy transfer (FRET) or supercoiling-dependent fluorescence quenching (SDFQ). With the FRET or SDFQ method, we performed steady-state kinetic studies for six different DNA topoisomerases including two type IA enzymes ( and DNA topoisomerase I), two type IB enzymes (human and variola DNA topoisomerase I), and two type IIA enzymes ( DNA gyrase and human DNA topoisomerase IIα). Our results show that all DNA topoisomerases follow the classical Michaelis-Menten kinetics and have unique steady-state kinetic parameters, , , and . We found that for all topoisomerases are rather low and that such low values may stem from the tight binding of topoisomerases to DNA. Additionally, we confirmed that novobiocin is a competitive inhibitor for adenosine 5\u27-triphosphate binding to DNA gyrase, demonstrating the utility of our assay for studying topoisomerase inhibitors

Evaluation of distance learning delivery of health information management and health informatics programmes: a UK perspective

Abstract The aim of the article is to review evaluations of distance learning programmes in health information management, in order to identify the critical success factors for such programmes and discuss future directions. The emphasis is on the UK experience, based partly on reflections on the experience of one programme at University of Wales Aberystwyth (now over 10 years old), and partly on a policy review conducted for the NHS Information Authority and the NHS Information Policy Unit. The methods are, as far as possible, those of a systematic review of existing research, with, additionally, an overview of relevant policy developments for lifelong learning. The topics covered include the aims, objectives and educational philosophies of the programmes. The evidence, combined with the UWA experience, indicates the importance of face-to-face interaction, to complement distance or virtual learning. A studentcentred approach to curriculum design and delivery is essential

Does device matter? Impacts of food-specific inhibition training on food choice, liking and approach bias when delivered by smartphone or computer.

Food-specific inhibition training (FSIT) requires users to inhibit responses to energy-dense (ED) food stimuli within a reaction time game. FSIT reduces choice and liking of ED foods. Research with the public shows larger effects when FSIT is delivered by computer versus smartphone. This pre-registered study is the first to compare computer-FSIT versus smartphone-FSIT in a controlled setting. Three-hundred-and-thirty-one adults were randomised to computer-FSIT, smartphone-FSIT or non-food control training (computer-delivered). In session 1, participants completed baseline measures of impulsive food choice, food approach bias (approach/avoid implicit association test), and food liking ratings, before completing eight minutes of FSIT/control training. In session 2, participants repeated the same training task, followed by the same measures of food choice, approach bias and liking. We hypothesised that FSIT groups would show healthier food choices, lower ED food liking, and reduced ED food approach bias at post-training compared to control. We expected no statistically significant differences between the two FSIT groups. Post-exclusions, data for 259 participants was analysed. Contrary to predictions, there was no evidence of significant group differences on any of the outcome measures. Baseline measures suggest participants already showed high approach to healthy foods, which may explain these null results
