D. N. V.; Subeshan, Balakrishnan; Uddin, M. NizamSuperhydrophobic properties have been present in nature for many millennia before human beings discovered their true capabilities and utilized them to revolutionize modern societies. The most familiar form of hydrophobicity found in nature is that of the lotus leaf, where its ultra-low water adhesion and self-cleaning properties make it one of the best hydrophobic elements formed naturally. Since its discovery, artificially created superhydrophobic elements have been used in many industries --maritime, automobile, and medical -- due to their self-cleaning, antibacterial, and corrosion-prevention properties. However, for a surface to become superhydrophobic, it must possess a greater roughness. To achieve this, microscopic- or nanoscopic-level modifications must be made to the surface through various experimentations. For a surface to be considered superhydrophobic, it must have a water contact angle greater than 150°. One cost-effective method of manufacturing superhydrophobic materials is three-dimensional (3D) printing (additive manufacturing), which has been gaining popularity in the recent past. A 3D printing design is initially created using computer-aided design (CAD) software. Then, the design information is transferred to a 3D printer through digital slicing of the CAD design. 3D printing allows the printing of objects with various functionalities at pre-designed locations in the object, so it is important to investigate these phenomena. This paper provides an overview of several studies that were conducted to achieve superhydrophobicity through the 3D printing process. The following section of the manuscript includes an introduction, literature review, methods of increasing surface roughness for superhydrophobicity, market-available 3D printing materials, and their applications, discussion on 3D printing technologies and concluding remarks.Item Incorporating theory into practice: A historical assessment of layout design and Bürolandschaft with practical applications to modern office landscapes using performance metrics(Association for Industry, Engineering and Management Systems (AIEMS), 2022-06) Couch, Andrew; Messimer, SherriThe historical upbringing of the theoretical foundations of layout planning and optimization provided several core principles from which other theories have been derived. Naturally, the development and transformation of layouts following modern tastes have unlocked new types of capabilities, but these benefits are not exempt from drawbacks. This study critically examines layout characterization and performance from both the historical and practical application perspectives. In fulfilling this objective, this study conducts an assessment of the existing body of foundational work in the domain of layout planning and Bürolandschaft, a German term that characterizes the conceptual nature of an office landscape, to capture the underlying motivations, insights, and benefits that are offered by this foundation. These theories are examined under the lens of a common focal point for many modern-day corporations: obtaining an ideal office layout. The historical findings imply that the manifestation of Bürolandschaft is closely related to the concept of an open office layout. Given these insights, an application of an open office layout to a modern-day organization is proposed. Furthermore, the resulting layout is assessed based on a variety of qualitative and quantitative layout performance metrics to observe the impact emerging from the application of theory to practice. More broadly speaking, the theoretical outcomes as suggested by historical developments are assessed in comparison to the outcomes resulting from a practical application.Item Does a municipality's wellness affect its business growth?(Association for Industry, Engineering and Management Systems (AIEMS), 2022-06) Arbogast, Gordon W.; Rich, David; Jadav, ArpitaThis study focuses on the health of a given population to determine if health indicators can be used as a predictor of business growth in a geographic region. A study that was focused on the wellness in a firm, concluded: "that firms can increase operational productivity through socially responsible health policies that improve both workers' wellness and economic value" (Gubner et.al., 2018). That study was typical of most papers on wellness. It analyzed the impact of a corporate wellness program on worker productivity. While interesting, it was severely limited in scope as it was based on only one firm. Most studies that examined the factors that contribute to growth in major areas are confined largely to cities and cite factors that do not include wellness. The factors most often mentioned are a city's: (i) natural resources surplus; (ii) industrialization and commercialization; (iii) development of transport and communication; (iv) economic pull; and (v) educational and recreational facilities. Other factors mentioned include a well-developed infrastructure, good quality, available human capital, and a decent ecosystem. Wellness is normally absent as a factor or is rarely mentioned. This study is different. It is focused on the role that wellness could play in the economic growth of a major area in the country. That major area is a Municipal Statistical Area (MSA) in the United States of America (USA). An MSA is not limited to a city, but may extend from one major city to several adjoining industrial areas in close proximity. Thus, this study takes a much more robust, macro-oriented approach. The research used multiple-regression modeling. It determined that there may well exist a positive relationship between the wellness of an MSA and the percent increase in business establishments in that MSA. The yearly percent increase in business establishments in an MSA was used as the response variable i.e., the business growth in an MSA. Two control variables were necessarily employed in the study to improve accuracy. The first was whether the MSA was in a Right-to-Work (RTW) state. The second was if the MSA existed in the Rust Belt (RB) area of the USA. A second research portion of this study used different statistical methods (ANOVA and MANOVA) to examine the impact of wellness on business growth and two additional explanatory variables (i.e., unemployment and annual salaries in an MSA). This analysis validated that increased MSA wellness is a driver variable that increases business growth and leads to lower unemployment and higher annual salaries in an MSA.Item Commercial airline passengers' willingness to fly with COVID-19 safety measures(Association for Industry, Engineering and Management Systems (AIEMS), 2022-06) D'Albert, Jordan; Magness, Andrew; Alqarni, Khalid; Wheeler, BrookeIn the commercial aviation industry, safety is always a primary concern, with a central focus on the well?being of passengers and crew members. Given the significance of safety, the COVID?19 pandemic has resulted in drastic changes to the way commercial airlines operate. The airline industry has had to adopt precautions to help ensure safety by minimizing the risk of transmission for both passengers and airline employees during air travel. We examined passengers' willingness to fly with various commercial airline COVID-19 safety precaution scenarios: control (none), face coverings (masks), negative PCR test, boarding and deplaning five rows at a time, and paired combinations of these precautions. The within-subject design assessed Willingness to Fly (Rice et al., 2015, 2020) for all scenarios in random order. Participants were recruited from the US Amazon Mechanical Turk (MTurk) user population. Willingness to fly was positive for all scenarios (N= 202). The control scenario, with no precautions listed, had the lowest willingness to fly (0.69); Scenario 3, negative PCR test required, had the highest willingness to fly (0.81). However, contrary to expectations, there was no statistically significant difference in willingness to fly between the scenarios. These results suggest that participants are willing to fly regardless of the precautions, meaning that air travelers are still willing to fly under the commonly used pandemic precautions or without.
