Since the start of the COVID 19 pandemic there has undoubtedly been an increase in social distancing orders, isolation, and overall general stress. The current outbreak has been proven to have a heavy impact on issues involving mental health. Social distancing mandates contributed to isolation, which in turn caused a surge in psychiatric disorders, either newly onset or exacerbating preexisting conditions (Torales, et al, 2020). Due to significant alterations in daily life, an increase in physical inactivity has already been proven to lead to deterioration of cardiovascular health (Pecanha et al, 2020). Stay at home orders have prevented otherwise healthy people from keeping up their daily exercise and eating habits, contributing to a heightened amount of mental health and hypertensive related issues.<br/>In addition to these health concerns, the pandemic has put stress upon pharmaceutical management practices. Drug utilization surges have led to an impact on patient care and management which requires careful measures to be taken to reduce the inflow of sick patients (Badreldin and Atallah, 2020). A global drug shortage has been a result of these drug utilizations. Understanding the alterations in the usage of specific medications such as prescription psychotropics, antihypertensive drugs, and antidiabetic agents can aid in population management and drug shortages.

Description
Infrared photodetectors, used in applications for sensing and imaging, such as military target recognition, chemical/gas detection, and night vision enhancement, are predominantly comprised of an expensive II-VI material, HgCdTe. III-V type-II superlattices (SLs) have been studied as viable alternatives for HgCdTe due to the SL advantages over HgCdTe: greater control of the alloy composition, resulting in more uniform materials and cutoff wavelengths across the wafer; stronger bonds and structural stability; less expensive substrates, i.e., GaSb; mature III-V growth and processing technologies; lower band-to-band tunneling due to larger electron effective masses; and reduced Auger recombination enabling operation at higher temperatures and longer wavelengths. However, the dark current of InAs/Ga1-xInxSb SL detectors is higher than that of HgCdTe detectors and limited by Shockley-Read-Hall (SRH) recombination rather than Auger recombination. This dissertation work focuses on InAs/InAs1-xSbx SLs, another promising alternative for infrared laser and detector applications due to possible lower SRH recombination and the absence of gallium, which simplifies the SL interfaces and growth processes. InAs/InAs1-xSbx SLs strain-balanced to GaSb substrates were designed for the mid- and long-wavelength infrared (MWIR and LWIR) spectral ranges and were grown using MOCVD and MBE by various groups. Detailed characterization using high-resolution x-ray diffraction, atomic force microscopy, photoluminescence (PL), and photoconductance revealed the excellent structural and optical properties of the MBE materials. Two key material parameters were studied in detail: the valence band offset (VBO) and minority carrier lifetime. The VBO between InAs and InAs1-xSbx strained on GaSb with x = 0.28 - 0.41 was best described by Qv = ÄEv/ÄEg = 1.75 ± 0.03. Time-resolved PL experiments on a LWIR SL revealed a lifetime of 412 ns at 77 K, one order of magnitude greater than that of InAs/Ga1-xInxSb LWIR SLs due to less SRH recombination. MWIR SLs also had 100's of ns lifetimes that were dominated by radiative recombination due to shorter periods and larger wave function overlaps. These results allow InAs/InAs1-xSbx SLs to be designed for LWIR photodetectors with minority carrier lifetimes approaching those of HgCdTe, lower dark currents, and higher operating temperatures.

Fashion is an inherently political and reflective medium for the daily ramblings and revolutions of a society. Much of the time the influence is subtle. Silhouettes and fabrics reflect different stances on conservatism, on sex, on the degrees to which we fetishize luxury, and on infinite other attitudes of an era. Other times the influence is extremely direct, with text printed on the clothing that explicitly articulates a current societal dynamic. I began exploring fashion in 2016, as the country had reached an unprecedented and linguistically weaponized divide.
While taking a fashion technology course under the instruction of Galina Mihaleva, I developed a tracksuit incorporating concealed LED displays that are capable of scrolling customizable text on the sides of the garment. I expanded on this futuristic execution of politically charged clothes by utilizing a more realistic application of the LED technology in the Bouis Vuitton project. This project is a collection of six white vinyl bags with semi-flexible LED displays projecting revolutionary slogans through the vinyl textile.
The bags act as an appropriate housing for technology that is intended for significantly longer use, as bags have a longer lifespan in wardrobes than clothes and return to trend more frequently. The production investment in the technology is more equitable to the investment in the production of a bag and facilitates the wearer’s broadcasting of concise messages. The result is a collection of functional, utilitarian pieces with a clean, futuristic look and a mixed modern and vintage silhouette scrolling pro-revolutionary messages.
Broadcasting the knock-off name ‘BOUIS VUITTON’, I’ve inserted only my first initial into the reputable luxury company and paired it with slogans: ‘EAT THE RICH’ and ‘HEADS WILL ROLL’. The collection articulates a sense of nihilism felt by the youngest generations growing up on the outside of a very exclusive economic and political sphere. Three upcycled vintage luggage pieces evoke associations with the white American upper-class society of the 1960s. The luggage pieces were retrofitted in white vinyl and white-enameled metal fixtures. Three additional soft bags made of the same material reflect a utilitarian style of functional bags on trend with Spring/Summer 2019 streetwear. For the runway presentation of the bags, the models are dressed in navy-colored Dickies boiler suits, white retro-style Fila sneakers, and white ascots reminiscent of the historical male ruffled cravat. The contradictions of iconic silhouettes from both upper and lower-class American fashion history further the juxtaposition of anti-capitalist slogans posted on luxury goods.
Bouis Vuitton: Bags for the Revolution is intended to embody an unapologetic disregard for established wealth and political power in the most public of venues: the sidewalk, the mall, the high and the low-income neighborhoods – wherever people are wearing clothes. Fashion is the modern protest that requires no permit, and the new poster is a luxury bag.

Description
Introduction: Electronic cigarettes (e-cigarettes) among youth has increased drastically in recent years. E-cigarettes are being used with nicotine which can lead to dependency. Healthcare providers (HPs) are in a unique position to advise against the use of e-cigarettes. Recent studies report a lack of formal education among HPs about e-cigarettes. The purpose of this quality improvement project is to examine how increasing e-cigarette awareness among HPs can change their behavior on patient counseling against e-cigarette use. Methods: A modified E-cigarette Knowledge, Beliefs and Attitude Questionnaire was proctored before and after a virtual educational training about e-cigarettes. All advanced HPs employed, in a Southwestern state, at the organization were invited to participate by email. Results: 29 participants completed the pre-survey, and 4 participants completed the post-survey. While 90% of the participants reported that they first learned about e-cigarettes through informal sources, 72% of the participants reported interest in learning more about e-cigarettes to enhance their practice. Further, a two-tailed Mann-Whitney U test was significant on the “e-cigarettes are helpful aid for smoking cessation” statement based on an alpha value of 0.05, U = 12, z = -2.69, p = .007. Conclusions: Increasing the knowledge about e-cigarettes among HPs is critical in decreasing nicotine use among the public. This project will help in the fight against the use of tobacco products, and adds to the literature on how formal education about e-cigarettes among HPs can increase their intention to screen and counsel patients.

Description
Objective: Substance use disorder (SUD) is an epidemic in the United States. Current standard of care for SUD continues to produce a 40-60% relapse rate. Treatment for SUD is costly and is not obtainable for many individuals. The purpose of this project is to implement mindfulness as an adjunct treatment for SUD to reduce relapse.
Methods: Voluntary program offered at a residential treatment center designed as a team-based project. The combined project includes exercise, wellness, and mindfulness. Adults over the age of 18, male or female with a diagnosis of SUD were eligible. Program consisted of three hourly sessions a week, for a total of three weeks. Sessions included one session of exercise and wellness, one session of mindfulness training, and a combined session. Mindfulness sessions included learning the seven pillars of mindfulness followed by guided meditation. Participants were given a mindfulness journal for daily exercises. Five Facet Mindfulness Questionnaire (FFMQ) was completed before program and on completion. Results: 11 of 22 participants completed the program. FFMQ total scores were analyzed with paired t-test with Wilcoxon signed rank to account for small sample size. Statistical significance was based on an alpha of 0.05, V=10.50, z=2.00 and p=0.45.
Conclusion: This project has the potential to decrease relapse rates by increasing mindfulness in individuals with SUD. Mindfulness training reduces cravings and negative thought processes. Implementing mindfulness training with current standard of care can be cost effective and recommended for all individuals with SUD.

Description
Background: Current standard of care practices for substance use disorder is inadequate in reducing relapse, with rates persistently 40-60% within one year of treatment. Unconventional approaches must be explored to reduce the risk of relapse, climbing rate of overdoses, and healthcare expenditures exceeding $740 billion annually. The purpose of this quality improvement project demonstrates how an evidence-based group exercise intervention, used as adjunctive support to standard addiction treatment, can reduce relapse and promote long-term recovery during a global pandemic. Methods: Aims of this project sought to enhance quality of life scores. Participants were recruited upon admission to a residential treatment center. Pre-posttest design utilized the World Health Organization Quality of Life Abbreviated scale to assess program impact on quality of life. Pre-program descriptive questions and a survey assessing prior addiction treatment were collected. Group exercise and wellness education sessions were delivered twice weekly in a live, interactive, virtual format with on-site participants. Upon completion, a post-program survey was utilized to capture the qualitative experiences of participants and impact of project to instill confidence to execute long-term sobriety. Results: Pre and post scores, as well as domain scores were clinically and statistically significant. Additionally, 80% of participants reported feeling more prepared to achieve long-term sobriety secondary to their participation in this project. Discussion and Conclusion: Results from this project demonstrate the positive impact that group-based exercise and lifestyle interventions can have on quality of life and long-term recovery. Peer support exercise programs may offer means to enhance addiction treatment and reduce overall healthcare expenditures globally by defying the odds of relapse.

Description
Objective: Obesity is the fifth leading cause of global death and is preventable. It affects all body systems and causes major chronic illnesses such as diabetes, heart diseases, stroke, and some cancers. The goal of this transtheoretical stages of changes (TSOC) theory-based project are as follows: To educate the participants of the project to be aware of obesity and its complications; motivate them to use community resources, and improve their body mass indexes (BMI), waist circumference (WC), motivation, quality of life (QOL) and lifestyle.
Methods: Twenty-three participants were recruited in a primary care clinic. Six participants dropped out during the project. All the randomly selected participants who met the criteria of obesity signed written informed consent and were provided a 4-digit code to maintain anonymity. Participants were motivated and educated using a handout, two pre-and post-project in-person nursing visits, and five telemedicine weekly nursing follow-ups visits. Pre- and post-surveys collected during in-person visits include data such as weight, BMI, WC, demographic data, comorbidities, lifestyle, motivation, QOL, TSOC, and utilization of community resources.
Results: Descriptive analysis and paired t-test is done utilizing Intellectus statistics software to measure the outcome. The results show improvement in dietary choices, physical activity, motivation, QOL, use of community resources, decrease in BMI, and WC. In paired t tests, results show clinical and statistical significance in BMI, WC, MOT and clinical significance in QOL. There was increase in the revenue at the project site due to reimbursement of the services provided for the patients.
Conclusion: The results are expected to develop practice change in preventing and treating obesity. More evidence-based projects and studies with large sample size are needed to develop improvement in the knowledge base of providers and current practice.

Description
Background: Existing substance use disorder guidelines are deficient in reducing relapse rates, evidenced by the substantial number of persons experiencing relapse within months of recovery, with most relapsing within one year. Current interventions lack community reinforcement approaches to reduce relapse and risk factors required to combat the extensive damages related to substance use as costs exceed $1 trillion annually. Guided by the Social Cognitive Model, this quality improvement project aims to explore how group exercise combined with community reinforcement reduces relapse. It aims to boost recovery capital by improving quality of life scores. Methods: A CrossFit instructor delivered personalized group exercise and wellness education in-person biweekly for six weeks. Adult residential treatment clients were eligible to participate recruited via a flyer upon treatment entry. A pre-intervention demographic questionnaire, a pre-/post World Health Organization Quality of Life Abbreviated scale (reliability ? = > 0.70) assessing intervention influence on the quality of life, and a post-intervention survey was administered. The lead investigator performed all data distribution and collection. Institutional Review Board approval safeguarded participants' rights and risks. Results: Pre/post improvements observed in all domains; psychological and environmental were statistically significant, while 100% of participants reported enhanced QoL, social support, & confidence related to long-term sobriety post-intervention. Discussion/Conclusion: Desired outcomes are increased quality of life scores to boost recovery capital. A sober community reinforcement approach combined with exercise may link to reducing relapse and total costs related to this growing public health crisis.

Implementation of a Suicidal Ideation Treatment Algorithm in a Military Medicine Primary Care Clinic
Description
Primary care providers (PCPs) are frequently the first line of treatment for suicidal ideation (SI) patients. Many PCPs report low self-efficacy in treating suicidal patients, leading to inappropriate treatment plans or avoidance of discussing SI. This quality improvement project based on the Uncertainty Reduction theory aimed to evaluate PCP's perceptions of an SI treatment algorithm and its impact on self-efficacy. Secondary aims included assessing PCP's confidence in treating suicidal patients and current treatment practices. A pre- then post-intervention survey design was utilized. All PCPs treating patients in a military medicine clinic were invited to participate in the project. Participants were sent a recruitment email containing the suicidal ideation treatment algorithm and a link to a survey developed with Qualtrics software. Participants were asked to review the SI algorithm, answer the baseline survey questions, and complete a second eight-week survey. For human subjects' protection, the survey responses were anonymous. Demographic data collected included years of clinical experience and licensure type. The data were evaluated with Intellectus software. Due to limited participation, N=4, there was insufficient data to determine the significance of implementing the SI algorithm in a primary care clinic. Central tendencies showed that most providers (n=3, 75.00%) felt less than confident treating suicidal patients. Half of the providers asked non-mental health patients about suicide less than 40% of the time (n=2, 50.00%). The data suggest that PCPs feel uncomfortable treating suicidal patients and may benefit from additional resources and training in this area.

How does the idea of the visible and invisible, tangible and intangible, interact with the garments on the body? Perception, to become aware through the sense, involves the way in which the eye sees space, both visible and invisible. The way in which we see objects are significant in our everyday life and how we evaluate it. The main pattern the garments encompass are the accordion pleating and the variety in which the pattern can be utilized; the accordion pleating can be scaled, attached together, and twisted around the body. Effervescence is a 6-look collection that entails the idea of perception. The results of the project include 3 completed looks, 3 3D print on fabric, and 8 3D print accessories. In this paper, I will explain the process of creating the collection, the experimentation, and the results.
