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.

Method Comparison for Odor Discrimination in Camponotus floridanus

Description

Complex animal societies consist of a plethora of interactions between members. To successfully thrive they must be able to recognize members and their kin, and to understand how they do this we need sufficient and reliable methods of testing. Eusocial

Complex animal societies consist of a plethora of interactions between members. To successfully thrive they must be able to recognize members and their kin, and to understand how they do this we need sufficient and reliable methods of testing. Eusocial insects are especially good at recognizing their nestmates, but the exact mechanism or how well they can discriminate is unknown. Ants achieve nestmate recognition by identifying varying proportions of cuticular hydrocarbons. Previous studies have shown ants can be trained to discriminate between pairs of hydrocarbons. This study aims to compare two methodologies previously shown to demonstrate odor learning to identify which one is the most promising to use for future odor learning experiments. The two methods tested were adapted from Sharma et al. (2015) and Guerrieri and d’Ettorre (2010). The results showed that the Guerrieri method demonstrated learning better and was more reliable and faster than the Sharma method. The Guerrieri method should be used in future experiments regarding odor learning discrimination

Breast Health Seeking Behaviors In Countries With Varying Health Coverage

Description

There is an enormous unmet need for services, education, and outreach to improve women’s breast health. Healthcare systems and insurance systems vary widely around the world, and this may play an important role in understanding variability in women’s breast health

There is an enormous unmet need for services, education, and outreach to improve women’s breast health. Healthcare systems and insurance systems vary widely around the world, and this may play an important role in understanding variability in women’s breast health knowledge and behavior globally. The goal of this study is to determine how varying healthcare systems in three countries (Japan, Paraguay, US) affect a woman’s likelihood of seeing a physician in regard to their breasts. For example, Japan is a clear example of a region that provides universal health insurance to its citizens. The government takes responsibility in giving accessible and equitable healthcare to its entire population (Zhang & Oyama, 2016). On the other hand, a country such as Paraguay is composed of both public and private sectors. In order for citizens to gain insurance, one would have to either be formally employed or choose to pay out-of-pocket for hospital visits (“Paraguay”, 2017). A country such as the United States does not have universal health insurance. However, it does have a mix of public and private sectors, meaning there is little to no coverage for its citizens. To accommodate for this, the United States came up with the Affordable Care Act, which extends coverage to the uninsured. Although the United States might be a country that spends more on healthcare than any other nation, there are residents that still lack healthcare (De Lew, Greenberg & Kinchen, 1992). This study, then, compares women’s breast health knowledge and behavior in Japan, Paraguay, and the US. Other variables, which are also considered in this study, that might affect this include wealth level, education, having general awareness of breast cancer, having regular health checks, and having some breast education. Using statistical analysis of breast check rates of women in Japan, Paraguay, and the United States, this research found that women sampled in Asunción, Paraguay check their breasts more often than either women sampled from Scottsdale, U.S. or Osaka, Japan. It was also found that women sampled from Paraguay were more confident in detecting changes in their breast compared to women sampled from the Japan or the US. Finally, it was noted that women sampled from Japan were least likely to partake in seeing a doctor in concern of changes in their breasts compared to women sampled from the other two research locations. These findings have relevance for the implementation of advocacy and public education about breast health.

Effect of Rexinoids on Inducing Effector T Cell Chemotaxis

Description

The retinoid-X receptor (RXR) can form heterodimers with both the retinoic-acid
receptor (RAR) and vitamin D receptor (VDR). The RXR/RAR dimer is activated by ligand all
trans retinoic acid (ATRA), which culminates in gut-specific effector T cell migration. Similarly,

The retinoid-X receptor (RXR) can form heterodimers with both the retinoic-acid
receptor (RAR) and vitamin D receptor (VDR). The RXR/RAR dimer is activated by ligand all
trans retinoic acid (ATRA), which culminates in gut-specific effector T cell migration. Similarly,
the VDR/RXR dimer binds 1,25(OH)2D3 to cause skin-specific effector T cell migration.
Targeted migration is a potent addition to current vaccines, as it would induce activated T cell
trafficking to appropriate areas of the immune system and ensure optimal stimulation (40).
ATRA, while in use clinically, is limited by toxicity and chemical instability. Rexinoids
are stable, synthetically developed ligands specific for the RXR. We have previously shown that
select rexinoids can enhance upregulation of gut tropic CCR9 receptors on effector T cells.
However, it is important to establish whether these cells can actually migrate, to show the
potential of rexinoids as vaccine adjuvants that can cause gut specific T cell migration.
Additionally, since the RXR is a major contributor to VDR-mediated transcription and
epidermotropism (15), it is worth investigating whether these compounds can also function as
adjuvants that promote migration by increasing expression of skin tropic CCR10 receptors on T
cells.
Prior experiments have demonstrated that select rexinoids can induce gut tropic migration
of CD8+ T cells in an in vitro assay and are comparable in effectiveness to ATRA (7). The effect
of rexinoids on CD4+ T cells is unknown however, so the aim of this project was to determine if
rexinoids can cause gut tropic migration in CD4+ T cells to a similar extent. A secondary aim
was to investigate whether varying concentrations in 1,25-Dihydroxyvitamin D3 can be linked to
increasing CCR10 upregulation on Jurkat CD4+ T cells, with the future aim to combine 1,25
Dihydroxyvitamin D3 with rexinoids.
These hypotheses were tested using murine splenocytes for the migration experiment, and
human Jurkat CD4+ T cells for the vitamin D experiment. Migration was assessed using a
Transwell chemotaxis assay. Our findings support the potential of rexinoids as compounds
capable of causing gut-tropic migration in murine CD4+ T cells in vitro, like ATRA. We did not
observe conclusive evidence that vitamin D3 causes upregulated CCR10 expression, but this
experiment must be repeated with a human primary T cell line.

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.

Investigating the Role of the Las and Rhl Quorum Sensing Systems in the Pathogenesis of Pseudomonas aeruginosa

Pseudomonas aeruginosa is an opportunistic bacterial pathogen commonly associated with increased morbidity and mortality in cystic fibrosis (CF) patients. To adapt to the CF lung environment, P. aeruginosa undergoes multiple genetic changes as it moves from an acute to a chronic infection. The resultant phenotypes have been associated with chronic infection and can provide important information to track the patient’s individualized disease progression. This study examines the link between the accumulation of QS genetic mutations and phenotypic expression in P. aeruginosa laboratory strains and clinical isolates. We utilized several plate-based and colorimetric assays to quantify the production of pyocyanin, rhamnolipids, and protease from paired clinical early- and late-stage chronic infection isolates across 16 patients. Exoproduct production of each isolate was compared to the mean production of pooled isolates to classify high producing (QS-sufficient) and low producing (QS-deficient) isolates. We found that over time P. aeruginosa isolates exhibit a reduction in QS-related phenotypes during chronic infections. Future research of the QS regulatory networks will identify whether reversion of genotype will result in corresponding phenotypic changes in QS-deficient chronic infection isolates.

Role of Metabolism in Antibiotic Resistance

Each year, more and more multi-drug resistant bacterial strains emerge, thus complicating treatment and increasing the average stay in the intensive care unit. As antibiotics are being rendered inefficient, there is a need to look into ways of weakening the internal state of bacterial cells to make them more susceptible to antibiotics. For this, we first need to understand what methods bacteria employ to fight against antibiotics. In this work, we have reviewed how bacteria respond to antibiotics. There is a similarity in response to antibiotic exposure and starvation (stringent stress) which changes the metabolic state. We have delineated what metabolism changes take place and how they are associated with oxidative stress. For example, there is a common change in NADH concentration that is tied to both metabolism and oxidative stress. Finally, we have compared the findings in literature with our research on an antibiotic-resistant RNA polymerase mutant that alters the gene expression profile in the general areas of metabolism and oxidative stress. Based on this thesis, we have suggested a couple of strategies to make antibiotics more efficient; however, as antibiotic-mediated killing is very complex, researchers need to delve deeper to understand and manipulate the full cellular response.

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.

Prenatal Supplementation Research

Description

When viewing vitamins and minerals, it is seen that they are essential for human life and vital for pregnancy. When paired with a healthy diet, prenatal supplements can allow for a healthy pregnancy and reduced maternal and infant health problems.

When viewing vitamins and minerals, it is seen that they are essential for human life and vital for pregnancy. When paired with a healthy diet, prenatal supplements can allow for a healthy pregnancy and reduced maternal and infant health problems. Within this thesis, I was able to break down each vitamin and mineral necessary for a healthy pregnancy and birth. Further, I had the opportunity to dive into the addition of Omega-3 Fatty Acid during pregnancy to add more evidence to the study.
