Prevalence of Phenylthiocarbamide (PTC) Taste Sensitivity and Colour Blindness in Tengger Tribe Population, Ranupani Village, Senduro, Lumajang

The taste of sensitivity of phenylthiocarbamide (PTC), is autosomal dominant trait inherited while the colour blindness is a sex linked genetic trait on the X chromosome. The purpose of this study was to determine the distribution of taster and non taster phenotypes, prevalence of color blindness, frequency of taster and non taster alleles, and frequency of color blind alleles, as well as pedigree analysis in non taster and color blind families. The research was conducted on the Tengger tribe, in Ranupani village, Senduro, Lumajang. Determination of the sample is carryout randomly. Detection of the ability to taste PTC was respondents to taste the PTC solution from the lowest concentration of 0.32mg/L (P13) to the highest concentration of 1300 mg/L (P1). Color blindness detection by the Ishihara method. The results of the study showed that the distribution of the taster was 98.1% while the non-taster was 1.9%. The allele frequency of the dominant taster (T) was 0.86 and the recessive allele non taster (t) is 0.14. The prevalence of color blindness in the population of the Tengger tribe was 0.63% and the allele frequency for color blindness was 0.013. The pedigree analysis of non taster family showed that non taster individuals were born from taster couple (Tt) or from couple of non taster (tt) with tasters (Tt) heterozigot. While the pattern of inheritance of color blindness was criss-cross inheritance pattern, which is passed from mother to son.

Two-Dimensional Biocompatible Plasmonic Lenses for Color Blindness Correction

Color blindness, or color vision deficiency (CVD), is an ocular disease that suppresses the recognition of different colors. Recently, tinted glasses and lenses have been studied as hopeful devices for color blindness correction. In this study, 2D biocompatible and flexible plasmonic lenses were fabricated using polydimethylsiloxane (PDMS) and an innovative, low-cost, and simple design based on the soft nano-lithography method. These lenses were investigated for correction of red-green (deuteranomaly) color blindness. The plasmonic lens proposed herein is based on the plasmonic surface lattice resonance (SLR) phenomenon and offers a good color filter for color blindness correction. The biocompatibility, low cost, and simple fabrication of these contact lenses can offer new insights for applications of color blindness correction.

Mobile Game “Color in Life” Development for Dichromatism Color Blind

The purpose of this research was to escalate players’ knowledge on color blindness by designing an educational video game which design was oriented to dichromatism color blind. The topic selection was based on the lack of players’ deeper knowledge on color blindness. The graphic and gameplay selection on this research was adjusted to the chosen color blind category. Research methods were conducted by analysis, development, and evaluation. Analysis was done by questionnaire. Development was done by game design document, UML, storyboard, and was implemented using Unity. Evaluation on 35 players, which are 32 with normal eyes and 3 with color blindness, was done by two approaches, which are t-test and questionnaire. The result of t-test was t(34) = -7.704, p < 0.05 and Enjoyment score on CEGE is 0.763 for normal eyes and 0.651 for colorblind. To conclude, there was an improvement on knowledge from the video game and the design was enjoyable.

Color Blind Test Using Ishihara Method for Mercu Buana University Prospective Students Selection

Mercu Buana University is a private university which consists of seven faculties. At the Faculty of Design and Creative Arts, Faculty of Communication Sciences and Faculty of Engineering, additional requirements are required for new student candidates, i.e. a color blindness free certificate. Color blindness is a vision disorder caused by the inability of the eye cone cells to perceive a certain spectrum of colors. There are many ways to test someone's color blindness, one of which is by using the Ishihara method. To obtain a color blindness free certificate, prospective students must visit a clinic or hospital, carry out the applicable color blind test procedure, then bring the results to campus. Based on these problems, the research was conducted with the aim of making a color blind test application that can issue a recommendation letter based on the test results of prospective new students. The system development method uses System Development Life Cycle. The results of the study were an android-based color blind test application that was able to detect color blindness using the Ishihara method and issued a recommendation letter based on the test results of prospective new students in the on-time application.

How Microaggressions Reinforce and Perpetuate Systemic Racism in the United States

The consequences of racial microaggressions are most often discussed at an interpersonal level. In this article, we contend that microaggressions play an important role in maintaining systems of racial oppression beyond the interpersonal context. Specifically, we illustrate how microaggressions establish White superiority in the United States by othering people of color (e.g., treating people of color as if they are not true citizens) and communicating that they are inferior (e.g., environmental exclusions and attacks, treating people of color as second-class citizens). We also present evidence that microaggressions play a role in protecting and reinforcing systemic racism. By obscuring systemic racism (e.g., false color blindness, denial of individual racism) and promoting ideas that maintain existing systemic inequalities (e.g., the myth of meritocracy, reverse-racism hostility), microaggressions provide cover and support for established systems of oppression. Overall, we find considerable evidence—from both empirical studies and real-world examples—that microaggressions contribute to the maintenance of systems of racial oppression in the United States. We conclude with a discussion of how we might begin to challenge this cycle by increasing awareness of systemic racism and the microaggressions that aid in its perpetuation.

Challenging the Myth of Color Blindness in Restorative Justice Programs

Using critical race theory and institutional ethnography as frameworks, this paper investigates the Extra-Judicial Sanctions (EJS) Program, as implemented in Calgary, Alberta, and its lack of ability to achieve transformative restorative justice in the cases of racialized immigrant youth. The failure to recognize the impact of race, ethnicity, and immigrant status in the Youth Criminal Justice Act is considered problematic as this paper challenges the notion of color blindness. It is suggested that a color-conscious approach be used in the EJS Program to incorporate inclusive institutional policies explicitly to foster a sense of belonging among racialized immigrant youth.
