Programmable Vibration Table Retrofit with Eagle Medical

This project aimed to repair and upgrade a vibration table used for package testing for the sponsor, Eagle Medical - a medical packaging and sterilization company based in Paso Robles, California. The current vibration table is not programmable and lacks circuit diagrams, making it difficult to repair. In addition, it is not functional due to internal circuitry issues and power requirements. To address these issues, the team will implement several upgrades to improve the product and allow for better random cyclic vibration testing. A full assessment of the existing vibration table will be conducted to ensure the viability of these proposed modifications for a successful outcome. The document provides information on the project\u27s background, objectives, and project management, including the design process, project timeline, and Gantt chart. Additionally, the document will provide information regarding our morphology, conceptual designs/evaluation, and failure analysis. This document also includes the detailed design, manufacturing plans, testing plans, and testing data/analysis, and instructions for use. We followed a 5-phase design process typically employed in industry: product discovery, project planning, product definition, conceptual design, and product development. During the Winter Quarter, we went through the first 4 phases, and all of Spring Quarter was spent in product development. In product discovery, we identified the needs of Eagle Medical and investigated other vibration tables on the market. During project planning, we mapped out our key deadlines using a Gantt chart. In product definition, we created the scope of the project and began creating our engineering specifications. In conceptual design, we took those specifications and started evaluating possible concepts using morphology. During product development, we built our prototype and tested it against our engineering specifications. The key customer requirements were that the new vibration table vibrates according to given standards, outputs frequency data, has vibration schedules, uses microcontrollers, has easily accessible data, updated/reliable electronics, and has a human-machine interface. The customer additionally wanted a circuit diagram, an easily serviceable table, and asked that we salvaged as much of the old table as possible. Our test plan revealed key results. The aesthetic satisfaction scored a 10. The vibration table achieved our max vibration goal of 18 m/s^2. We showed that the vibration table does have accurate control of the rotations per minute. We also showed that the motor wire temperature did not change, indicating that our wires are properly specified. We showed that the power supply had very little variance, so our electronics should be safe from voltage spikes. We showed that it takes approximately 5.2 seconds to upload a vibration test. We also showed that the emergency stop works with 100% certainty. Finally, we performed GUI unit testing and all units passed

The study used the descriptive method of research. The respondents were 165 radiologic technology students of De La Salle-Health Sciences Campus selected using stratified random sampling. The questionnaire consisted of a five-point scale which was adapted from the study of Taeza et al. (2006). Frequency, percentage, means, t-test and ANOVA were the statistical tools used. The following conclusions were drawn: (1) The respondents considered the student services offered by De La Salle-Health Sciences Campus, specifically Accounting Office, Canteen, Guidance/Student Affairs Office and Library, as Very Good. This means that the given services almost meet the standard of the respondents. However, respondents evaluated the Registrar’s Office as Good. The respondents fairly rated the services provided by the Registrar’s Office; (2) Age was a factor to consider in the evaluation of the respondents to the student services programs of De La Salle-Health Sciences Campus; (3) Gender did not affect the evaluation of the respondents. Male and female had same evaluation of the student services programs of De La Salle-Health Sciences Campus; (4) Student type did not affect the respondents’ evaluation of the Student Services Program of De La Salle-Health Sciences Campus. Regular and irregular students had the same evaluation; (5) Year level is a factor to consider in the evaluation of the respondents to the student services program of De La Salle-Health Sciences Campus

“Bakit Ka Kumakayod?” Developing a Filipino Needs Theory of Motivation

This study utilized a mixed method sequential exploratory strategy in investigating the needs of the Filipino working population and the relationship between these needs and employee engagement. In the first phase, workers were interviewed to determine the needs that motivate them. In the second phase, a survey with 302 workers elicited four types of needs: job-related, career-related, organization-related, and familyrelated. Among these, family is a novel addition to the extant theories of work motivation in the West. The importance and presence of these four factors were all significantly correlated with employee engagement. Three models were tested to describe the importance and presence of needs as predictors of employee engagement. The best fitting model was the presence of needs as predictors of engagement. Among the needs, it was those related to the job that predicted employee engagement

Awareness and knowledge on cultural competence of speech-language pathology students clinicians in De La Salle Medical and Health Sciences Institute: A self-assessment survey

This study assessed the cultural competence of Speech-Language Pathology (SLP) student clinicians enrolled in Clinical Practicum 2 (SP-CPR 452) at De La Salle Medical and Health Sciences Institute (DLSMHSI) during the academic year 2023-2024. The objectives were to describe demographic characteristics and gauge cultural knowledge and awareness of SLP student clinicians through a self- assessment survey. A descriptive cross-sectional design was utilized, with data collected from 37 level 4 SLP student clinicians. The survey tool, developed by adapting and combining items from the Cultural Competence Check-In: Self Reflection (ASHA, 2021) and The Korean version of Cultural Competence (K- CCSN) (Chae and Lee, 2014), was distributed with the dean\u27s approval, ensuring all ethical guidelines were adhered to. Results revealed high levels of cultural awareness and knowledge among participants, particularly in recognizing LGBTQIA+ issues, patient rights, and language barriers. However, deficits were identified in understanding cultural nuances related to eye contact, pain perception, and proxemics. Methodological limitations included response biases and a modest response rate. The study emphasizes the significance of cultural competence in delivering effective speech and language therapy services and advocates for further research to refine assessment tools and methodologies

Evaluation of the Xpert MTB Host Response assay for the triage of patients with presumed pulmonary tuberculosis: a prospective diagnostic accuracy study in Viet Nam, India, the Philippines, Uganda, and South Africa

BackgroundNon-sputum-based triage tests for tuberculosis are a priority for ending tuberculosis. We aimed to evaluate the diagnostic accuracy of the late-prototype Xpert MTB Host Response (Xpert HR) blood-based assay.MethodsWe conducted a prospective diagnostic accuracy study among outpatients with presumed tuberculosis in outpatient clinics in Viet Nam, India, the Philippines, Uganda, and South Africa. Eligible participants were aged 18 years or older and reported cough lasting at least 2 weeks. We excluded those receiving tuberculosis treatment in the preceding 12 months and those who were unwilling to consent. Xpert HR was performed on capillary or venous blood. Reference standard testing included sputum Xpert MTB/RIF Ultra and mycobacterial culture. We performed receiver operating characteristic (ROC) analysis to identify the optimal cutoff value for the Xpert HR to achieve the target sensitivity of 90% or more while maximising specificity, then calculated diagnostic accuracy using this cutoff value. This study was prospectively registered with ClinicalTrials.gov, NCT04923958.FindingsBetween July 13, 2021, and Aug 15, 2022, 2046 adults with at least 2 weeks of cough were identified, of whom 1499 adults (686 [45·8%] females and 813 [54·2%] males) had valid Xpert HR and reference standard results. 329 (21·9%) had microbiologically confirmed tuberculosis. Xpert HR had an area under the ROC curve of 0·89 (95% CI 0·86-0·91). The optimal cutoff value was less than or equal to -1·25, giving a sensitivity of 90·3% (95% CI 86·5-93·3; 297 of 329) and a specificity of 62·6% (95% CI 59·7-65·3; 732 of 1170). Sensitivity was similar across countries, by sex, and by subgroups, although specificity was lower in people living with HIV (45·1%, 95% CI 37·8-52·6) than in those not living with HIV (65·9%, 62·8-68·8; difference of 20·8%, 95% CI 13·0-28·6; p<0·0001). Xpert HR had high negative predictive value (95·8%, 95% CI 94·1-97·1), but positive predictive value was only 40·1% (95% CI 36·8-44·1). Using the Xpert HR as a triage test would have reduced confirmatory sputum testing by 57·3% (95% CI 54·2-60·4).InterpretationXpert HR did not meet WHO minimum specificity targets for a non-sputum-based triage test for pulmonary tuberculosis. Despite promise as a rule-out test that could reduce confirmatory sputum testing, further cost-effectiveness modelling and data on acceptability and usability are needed to inform policy recommendations.FundingNational Institute of Allergy and Infectious Diseases of the US National Institutes of Health.TranslationsFor the Vietnamese and Tagalog translations of the abstract see Supplementary Materials section
