    Low thrust orbit transfer trajectory optimization
    (Wichita State University. Graduate School, 2015-04-24) Vijayan, Sainath; Dutta, Atri
    In recent years, all electric satellites have had a growing presence in the space industry. The 702- SP family developed by Boeing is to be used for telecommunication satellites. This spawns the need for analyzing mission scenarios in order to achieve the most efficient way of deploying such satellites. The purpose of this poster is to analyze the different approaches to Low Thrust Spacecraft Trajectory optimization. One of the methods, developed by the author uses a feedback control law which allows the user to minimize an arbitrary objective set by mission designers. It also allows for a combination of objectives like minimum fuel and minimum time transfers. Minimizing radiation damage is another objective that is of importance in these kind of scenarios due to the long transfer times. The second method is a direct optimization routine. While this method has been around longer, convergence to a solution is not guaranteed and depends on initial guesses provided by the user. The third method is a combination of the first two methods and allows for multi-objective optimization. Extensive research of existing literature has shown that such a trajectory optimization method does not exist. The advantage of this method is that it will be able to overcome the shortcomings of the individual components and provide a comprehensive framework for mission designers to work with. The author will go over the merits and drawbacks of the different methods as well as compare the performance of all the methods for multiple scenarios. Some of these metrics will include rate of change of inclination, radius and fuel mass. In addition to this, the author will also introduce new performance objectives that could be of interest to mission designers and will discuss the method of implementing them into all of the mentioned methods.

    Interprofessional care and cesarean section rates: A systematic review
    (Wichita State University. Graduate School, 2015-04-24) Boardman, Emily; Jerome, Rachel; Temaat, Rebecca; Woods, Nikki Keene; Thiessen, Kellie
    The cesarean delivery rate in the United States steadily rose from the mid-1990s until 2009 from 21% to 33%; greater than the upper limit of 15% recommended by the World Health Organization. Non-medically indicated cesarean sections are associated with avoidable maternal complications and risks. Interprofessional models of care are the provision of comprehensive health services to patients by multiple health care professionals. Preliminary evidence demonstrates a correlation between interprofessional models of care and improved outcomes. However, the relationship has not been well studied. The purpose of this systematic review was to determine if interprofessional models of care were associated with lower cesarean section rates. The review was conducted according to systematic reviews for social science (Petticrew and Roberts, 2006). The practical screen included electronic databases including Pubmed, Cochrane Library, CINAHL, web of science, and grey literature. Search terms included a combination of free-text and thesaurus terms for concepts including "caesarean section, interdisciplinary care, maternal health service, midwifery, and physicians," combined with a qualitative and quantitative methods filter, respectively. Specific inclusion criteria (e.g., experimental design, time period 1970-2014, cesarean section outcome measure) and exclusion criteria (e.g., non- English publication) were used. A methodological screen was conducted to ensure the search was exhaustive and included a review of the reference sections in each of the retrieved articles. Two reviewers independently assessed all papers against the inclusion criteria, with any disagreement discussed and resolved by study team. Data was abstracted from each article (e.g., study design, participant characteristics, and sample size). No meta-analysis was conducted. The search returned 1366 articles for review; 1320 were excluded due to lack of interprofessional care, editorial pieces, lack of experimental design/outcome measure, or review articles, after reviewing titles and abstracts. Of the remaining 46 studies, 11 remained after a full-text evaluation. The other 35 were excluded for lack of outcome measure, commentary pieces, or lack of interprofessional care. The included articles were from 1991-2013 and included both US and international settings. The majority of articles 73% (n=8) reported lower cesarean section rates among women receiving interprofessional maternity care. The other three articles reported no difference. Other improvements associated with interprofessional care were more likely to breastfeed exclusively, infants were born at greater birth weights, and more frequent term deliveries. Interprofessional health care teams work toward promoting client-centered, collaborative, and shared decision-making regarding health issues. This interprofessional model of care could be utilized more often in the U.S. to address high cesarean section rates.

    DKA in a 12-month-old infant with new onset type 1 diabetes mellitus: A case report
    (Wichita State University. Graduate School, 2015-04-24) Beran, Miranda; Smith, Kirsten; Stout, Kevan; Wallace, Michelle
    Introduction: Type I diabetes mellitus (TIDM) has a bimodal peak in the onset of the disease. Most children are diagnosed between the ages of 4-6 and 10-14 years. It can be difficult to diagnose diabetes in children of a very young age, and it is often not high on the list of differential diagnoses for the provider. Without early recognition these children are at risk of developing diabetic ketoacidosis (DKA), a life threatening complication of T1DM. Children are not routinely screened for T1DM and it is more difficult to recognize the symptoms of DKA in a very young child, leaving this population vulnerable. Case description: A 12-month-old female presented to the emergency department on the advice of a nearby immediate care facility for dehydration and presumed gastroenteritis. The child had been vomiting for several days with loose stools. Her oral intake had decreased over several days and on the day of the visit she had refused to take anything by mouth. The child became increasingly lethargic throughout the day. In the emergency department she was noted to have sunken eyes, dry mucous membranes, and had rapid, deep breathing. The child appeared drowsy, cried on initial exam and responded to pain. While in the emergency department the child's urine output was noted to be out of proportion to her hydration status. A beside blood glucose meter was unable to evaluate the level and read "high". The presumptive diagnosis of diabetic ketoacidosis was made and intravenous rehydration was initiated. Laboratory results confirmed ketoacidosis and hyperglycemia. Discussion: The diagnosis of DKA in a young patient requires a thorough history and physical exam as well as appropriate diagnostic tests. Among children with TIDM, DKA is a serious consequence and responsible for significant morbidity and mortality. The clinician should take into account family history of TIDM, socioeconomic status, lack of health insurance, and level of parental education. Early recognition of DKA would reduce morbidity, mortality and healthcare costs.

    Attitudes toward healthcare entrepreneurship among College of Health Professions students
    (Wichita State University. Graduate School, 2015-04-24) Siler, Dustin; Ellis, Joshua; Bukonda, Ngoyi K.Z.
    Background: Healthcare systems in developing countries are largely government-run enterprises. Limited facilities and unequal distribution of clinics creates areas of limited access to healthcare. In response, some private-owned facilities have emerged with the potential to offset the disparities created by governmental inadequacies. Previous research suggests that most entrepreneurs in healthcare have previous medical exposure. To date we have found no research specific to students in health professions programs evaluating interest toward engaging in healthcare entrepreneurship. The attitudes, beliefs, and inclinations of this population may provide insight into encouraging or dissuading factors. Purpose: To gain understanding of the attitudes, beliefs, and inclinations of health professions students toward entrepreneurship; data which may be useful in creating a model for development and implementation of strategies encouraging students to engage in healthcare entrepreneurship in developing countries. Methods: A thirty question survey was distributed electronically to all Physician Assistant students at Wichita State University for the classes of 2014-2016 with anticipated further distribution to all College of Health Professions students. The survey asks demographic and background questions such as age, gender, marital status, hometown, program of study, education and professions of parents, and previous entrepreneurial experience. A Likert scale is used to assess students' predisposing factors, enabling factors, and reinforcing factors toward healthcare entrepreneurship. To date twenty-five of a desired 150 responses have been received. Preliminary data is being analyzed using Qualtrics software. Means with standard deviation and percentages will be used to analyze descriptive data. Frequencies, correlation tests, t-tests, Chi- Square tests and ANOVA will be used as appropriate. Statistical significance is established as alpha ? 0.05. Expected Results and Benefits of Research: Initial review of data shows 72% of respondents had parents who started a business but 71% have had no personal exposure to business classes. Responses are equally split between those who have considered starting a business and those who have not. A majority of responses feel that it would be easier to work for an established healthcare organization and that the current healthcare delivery system in the U.S. discourages starting a healthcare business. Through further data analysis we expect to find additional reasons for decreased entrepreneurial interest include: lack of incentive, lack of funding, minimal encouragement from professional programs or colleagues, and professional immaturity. This study, by targeting students in health professions programs, will find application in developing strategies for future research and understanding areas requiring greater focus in order to overcome current barriers.
