ABSTRACT

BACKGROUND: Essential skills for respiratory therapists extend beyond the traditional scope of therapy. Respiratory therapists are expected to communicate effectively, deliver bedside education, and practice within interprofessional teams. Respiratory therapy entry-to-practice program accreditation standards require evaluation of student competence in communication and interprofessional practice. This study aimed to determine if entry into practice programs include curriculum and competency evaluation for oral communication, patient education, telehealth, and interprofessional activities. METHODS: The primary objective was to identify the curriculum and method of competency evaluation. The secondary objective was to compare degree programs. Directors of accredited respiratory therapy programs were invited to complete an anonymous survey with regard to degree program type, oral communication, patient education, learning strategies, telehealth, and interprofessional activities. Degree programs were classified as associate's of science 2 year, associate's of science < 2 year, or bachelor's of science. RESULTS: Of 370 invited programs, respondents in 136 programs (37%) completed the survey. Oral communication competence was evaluated by 82%. Patient education curriculum and competency evaluation were reported by 86% and 73%, respectively. Telehealth was rarely included or evaluated. Interprofessional activities were included by 74%, of whom 67% evaluated competency. Bachelor's of science programs were more likely to include a specific patient education course (P = .004), evaluate oral communication competency with unpaid preceptors (P = .036), and evaluate interprofessional competence through formal interprofessional programs (P = .005). Associate's degree 2-year programs used laboratory proficiency for patient education competency evaluation more often than other programs (P = .01). associate's of science < 2-year programs were more likely to include simulation experiences that involved motivational interviewing (P = .01). CONCLUSIONS: Differences exist among program types for curriculum and competency evaluation. Telehealth was rarely included or evaluated at any degree level. Programs should evaluate the need for enhanced patient education and telehealth instruction.

ABSTRACT

The deposition of increased volumes of Cu down an interconnect through-hole via (THV) of a Printed Circuit Board (PCB) is highly desirable for the fabrication of increasing component density and PCB stacks. A quality metric, called micro-throwing power, characterises the volume of Cu that can be deposited within a THV. In this paper, we analyse the influence of 1 ± 0.05 MHz megasonic (MS) assisted agitation applied to copper (Cu) electroplating baths on the micro-throwing ability of a standard, non-filling Cu electroplating solution. Our results indicate that megasonic agitation is shown to increase the Cu deposition volume within a THV by 45% for an increase of MS pressure from 225 W to 450 W, highlighting the significance of acoustic pressure as a key parameter to control MS THV plating volume. Bulk fluid flow rate within a 500 L plating tank is shown to increase by 150% due to Eckhart acoustic streaming mechanisms, compared to existing bath agitation techniques and panel movement. From MS plating experiments and COMSOLTM finite element acoustic scattering simulations, transducer orientation is shown to influence plating performance, with higher-order acoustic resonant modes forming within THVs identified as the cause. Simulations indicate that higher potential acoustic energy was coupled into a 0.200 mm diameter THV cavity, width-to-length aspect ratio (ar): 8:1, than a larger cavity of diameter 0.475 mm, ar 3.4:1. The maximum acoustic energy coupled into THV cavity is observed for a wavefront propagating along the axis of the cavity entrance, indicating an ideal alignment for the MS plating setup.

ABSTRACT

In this research experimental and simulated analysis investigates the influence of megasonic (MS; 1 ±â€¯0.05 MHz) acoustic-assisted electroplating techniques, with respect to the fabrication of through-hole via (THV) and blind-via (BV) interconnects for the Printed Circuit Board (PCB) industry. MS plating of copper down THV and BV interconnects was shown to produce measurable benefits such as increased connectivity throughout a PCB and cost savings. More specifically, a 700% increase of copper plating rate was demonstrated for THVs of 175 µm diameter and depth-to-width aspect ratio (ar) of 5.7:1, compared with electrodeposition under no-agitation conditions. For BVs, a 60% average increase in copper thickness deposition in 150 µm and 200 µm, ar 1:1, was demonstrated against plating under standard manufacturing conditions including bubble agitation and panel movement. Finite element modelling simulations of acoustic scattering revealed 1st harmonic influence for plating rate enhancement.

ABSTRACT

BACKGROUND & METHOD: A survey was distributed to 77 Space Shuttle flight crew members; 40 responded covering 71 missions. The goal was to capture historical information before Shuttle retirement and to better understand subjective experiences of illusory sensations due to the transition from 1-G to microgravity and back. RESULTS: We analyzed the response data to answer four questions: 1) Do older astronauts suffer more from illusory sensations than younger astronauts? We conclude that they do not because younger flight crew had about twice the rate of illusory sensations as older flight crew. 2) Do trial head motions during re-entry in an effort to hasten readaptation to 1-G really help? Apparently not because those who made trial head motions had a 38% rate of illusory sensations whereas those who did not make trial head motions had a 15% rate of illusory sensations. 3) Do symptoms decrease as flight experience increases? Yes, as reported in other publications, although there are individual exceptions. 4) Do longer duration missions lead to more illusory sensations and readaptation difficulties than shorter duration missions? Yes, the rate of illusory sensations for longer missions was 38%, whereas it was 24% for shorter missions. DISCUSSION: Based upon our results, long-duration missions may induce orientation problems that could have significant mission impacts.
