This essay examines national leaders’ shaping of K-pop into a foreign export, specifically looking into how K-pop is used as a soft power for South Korea. I also examine how effective K-pop is as a soft power. Because of its growing global popularity and use of K-pop artists for international relations, such as Red Velvet performing for Kim Jong Un, we might expect K-pop to act as the gateway into South Korean culture, often being the first exposure that other countries have into this country’s way of life. Through a qualitative analysis of resources ranging from news articles, videos, and social media posts, we see that K-pop idols, a term for K-pop celebrities, are heavily groomed and shaped by their labels to promote the South Korean national brand. Combined with a well-made business model to appeal to different countries, they also create sentiment for South Korean culture throughout the world with the support of the government and a strong fanbase. This plan is extremely effective in generating revenue for a multitude of South Korean brands beyond K-pop and even fosters South Korean affection in North Korea.

Surface Mechanical Attrition Treatment (SMAT) of 7075 Aluminum Alloy to Induce a Protective Corrosion Resistant Layer

Description

This paper investigates Surface Mechanical Attrition Treatment (SMAT) and the influence of treatment temperature and initial sample surface finish on the corrosion resistance of 7075-T651 aluminum alloy. Ambient SMAT was performed on AA7075 samples polished to 80-grit initial surface roughness.

This paper investigates Surface Mechanical Attrition Treatment (SMAT) and the influence of treatment temperature and initial sample surface finish on the corrosion resistance of 7075-T651 aluminum alloy. Ambient SMAT was performed on AA7075 samples polished to 80-grit initial surface roughness. Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) tests were used to characterize the corrosion behavior of samples before and after SMAT. Electrochemical tests indicated an improved corrosion resistance after application of SMAT process. The observed improvements in corrosion properties are potentially due to microstructural changes in the material surface induced by SMAT which encouraged the formation of a passive oxide layer. Further testing and research are required to understand the corrosion related effects of cryogenic SMAT and initial-surface finish as the COVID-19 pandemic inhibited experimentation plans.

Oedipus Wrought: Morality and Fear in Oedipus Rex Across Media

This project analyzes the use of fear appeals in transmitting a moral of self-realization in the drama Oedipus Rex and its adaptations into painting and film. It draws upon earlier work in media ecology, adaptation, and studies of emotions in media. It proposes that what distinguishes media from one another is the unique way that each medium stimulates the reader to draw from their own experiences with life and literature. Alternatively, what unites media is the cross platform assimilation of author and reader reality. More specifically, it asserts that print stimulates the reader via immersion, that painting achieves this same effect by acting as a proxy for the reader to embody the image before them, and that film stimulates the viewer as a result of emotive focus. Collectively, it concludes that when it comes to Oedipus and its many forms, the plays utilize fear to communicate the moral through both surface and dense texts, while painting adaptations focus on dense texts, and the filmic adaptations emphasize their surface equivalent. The project’s significance rests in its challenge to Marshal McLuhan’s technological determinism. On exposing the effects that a reader’s varied mindset can have on a medium’s ability to communicate its message, the project highlights that the relationship between humankind and media is not so deterministic and is more complex than McLuhan would have us believe.

The Development of Marketing with Respect to Retro-Acculturation

With the United States' diverse group of people, diverse set of beliefs and diverse cultural backgrounds, it’s no wonder that over the last few decades there has been a 51 percent increase in second-generation Americans in the United States (Child Trends, 2018). Though each of these second- and third-generation Americans experience life in the U.S. vastly different, the common steps of self-identity, acculturation and assimilation persist. However, what is often missed with this seemingly linear process is the delineating step: retro acculturation. Their sense of disconnect sparks a feeling of blurred identity, introducing the phenomenon of retro- acculturation, or an individual’s conscious efforts to connect to their heritage in new ways. Understanding the “why” behind this revelation is essential in understanding the “how”- or the actions taken by the individual to connect with their withdrawn culture. A deeper understanding of retro-acculturation and its processes is essential to leveraging a successful marketing effort in order to reach this demographic. As this population steadily reaches a larger population and quickly gains consumer buying power, it is important to be taking note of new and innovative ways of making lasting impressions on this demographic. This study focuses on exploring and discovering why individuals experience retro-acculturation and their triggers, as well as what approaches they use to connect to their heritage culture. Additionally, the insights gained were leveraged to provide recommendations as to how business can more effectively market to reach this demographic.

This paper outlines the development of a script which utilizes a series of user-defined input parameters to construct base-level CAD models of aircraft landing gear. With an increased focus on computation development of aircraft models to allow for a rapidprototyping design process, this program seeks to allow designers to check for the validity of design integration before moving forward on systems testing. With this script, users are able to visually analyze the landing gear configurations on an aircraft in both the gear up and gear down configuration. The primary purpose this serves is to determine the validity of the gear's potential to fit within the limited real estate on an aircraft body. This, theoretically, can save time by weeding out infeasible designs before moving forward with subsystem performance testing. The script, developed in Python, constructs CAD models of dual and dual-tandem main landing gear configurations in the CAD program Rhino5. With an included design template consisting of 33 parameters, the script allows for a reasonable trade off between conciseness and flexibility of design.

Automation in a Progressive Economy: The Race between Humans and Technology

Description

For as long as humans have been working, they have been looking for ways to get that work done better, faster, and more efficient. Over the course of human history, mankind has created innumerable spectacular inventions, all with the goal of making the economy and daily life more efficient. Today, innovations and technological advancements are happening at a pace like never seen before, and technology like automation and artificial intelligence are poised to once again fundamentally alter the way people live and work in society. Whether society is prepared or not, robots are coming to replace human labor, and they are coming fast. In many areas artificial intelligence has disrupted entire industries of the economy. As people continue to make advancements in artificial intelligence, more industries will be disturbed, more jobs will be lost, and entirely new industries and professions will be created in their wake. The future of the economy and society will be determined by how humans adapt to the rapid innovations that are taking place every single day. In this paper I will examine the extent to which automation will take the place of human labor in the future, project the potential effect of automation to future unemployment, and what individuals and society will need to do to adapt to keep pace with rapidly advancing technology. I will also look at the history of automation in the economy. For centuries humans have been advancing technology to make their everyday work more productive and efficient, and for centuries this has forced humans to adapt to the modern technology through things like training and education. The thesis will additionally examine the ways in which the U.S. education system will have to adapt to meet the demands of the advancing economy, and how job retraining programs must be modernized to prepare workers for the changing economy.

The Effectiveness of Inhibition and Biofilm Disruption on Antibiotic Resistant E. coli

The purpose of this study was to observe the effectiveness of the phenylalanyl arginine β-naphthylamide dihydrochloride inhibitor and Tween 20 when combined with an antibiotic against Escherichia. coli. As antibiotic resistance becomes more and more prevalent it is necessary to think outside the box and do more than just increase the dosage of currently prescribed antibiotics. This study attempted to combat two forms of antibiotic resistance. The first is the AcrAB efflux pump which is able to pump antibiotics out of the cell. The second is the biofilms that E. coli can form. By using an inhibitor, the pump should be unable to rid itself of an antibiotic. On the other hand, using Tween allows for biofilm formation to either be disrupted or for the biofilm to be dissolved. By combining these two chemicals with an antibiotic that the efflux pump is known to expel, low concentrations of each chemical should result in an equivalent or greater effect on bacteria compared to any one chemical in higher concentrations. To test this hypothesis a 96 well plate BEC screen test was performed. A range of antibiotics were used at various concentrations and with varying concentrations of both Tween and the inhibitor to find a starting point. Following this, Erythromycin and Ciprofloxacin were picked as the best candidates and the optimum range of the antibiotic, Tween, and inhibitor were established. Finally, all three chemicals were combined to observe the effects they had together as opposed to individually or paired together. From the results of this experiment several conclusions were made. First, the inhibitor did in fact increase the effectiveness of the antibiotic as less antibiotic was needed if the inhibitor was present. Second, Tween showed an ability to prevent recovery in the MBEC reading, showing that it has the ability to disrupt or dissolve biofilms. However, Tween also showed a noticeable decrease in effectiveness in the overall treatment. This negative interaction was unable to be compensated for when using the inhibitor and so the hypothesis was proven false as combining the three chemicals led to a less effective treatment method.

An in-depth analysis on the effects vortex generators cause to the boundary layer separation that occurs when an internal flow passes through a diffuser is presented. By understanding the effects vortex generators demonstrate on the boundary layer, they can be utilized to improve the performance and efficiencies of diffusers and other internal flow applications. An experiment was constructed to acquire physical data that could assess the change in performance of the diffusers once vortex generators were applied. The experiment consisted of pushing air through rectangular diffusers with half angles of 10, 20, and 30 degrees. A velocity distribution model was created for each diffuser without the application of vortex generators before modeling the velocity distribution with the application of vortex generators. This allowed the two results to be directly compared to one another and the improvements to be quantified. This was completed by using the velocity distribution model to find the partial mass flow rate through the outer portion of the diffuser's cross-sectional area. The analysis concluded that the vortex generators noticeably increased the performance of the diffusers. This was best seen in the performance of the 30-degree diffuser. Initially the diffuser experienced airflow velocities near zero towards the edges. This led to 0.18% of the mass flow rate occurring in the outer one-fourth portion of the cross-sectional area. With the application of vortex generators, this percentage increased to 5.7%. The 20-degree diffuser improved from 2.5% to 7.9% of the total mass flow rate in the outer portion and the 10-degree diffuser improved from 11.9% to 19.2%. These results demonstrate an increase in performance by the addition of vortex generators while allowing the possibility for further investigation on improvement through the design and configuration of these vortex generators.

The objective of this project was to design an electrically driven centrifugal pump for the Daedalus Astronautics @ASU hybrid rocket engine (HRE). The pump design was purposefully simplified due to time, fabrication, calculation, and capability constraints, which resulted in a lower fidelity design, with the option to be improved later. The impeller, shroud, volute, shaft, motor, and ESC were the main focuses of the pump assembly, but the seals, bearings, lubrication methods, and flow path connections were considered as elements which would require future attention. The resulting pump design is intended to be used on the Daedalus Astronautics HRE test cart for design verification. In the future, trade studies and more detailed analyses should and will be performed before this pump is integrated into the Daedalus Astronautics flight-ready HRE.
