Abstract

The general public claims that there are socially agreed rules of honor and that the use of honorary titles is a matter of complying with those rules, and researchers often claim this too. This research aims to identify the kinds of the honorifics used by English and Buginese Bone language, and to analyze the use of the honorific in used English and Buginese Bone focused on the shift of honorifics due to the promotion as a government officer. This was comparative study between English and Buginese language in respect someone in order to highlight the social status and rank of job and to show respect and to dignify social status. This research used the descriptive qualitative method while the English data were obtained through the English movies that are Black Widow, and The Intern, as well as the news posted at BBC news.com about people who receive awards in the form of titles while Buginese data were obtained through the participants recording and note-taking. The research result show that in English almost every year the country's leaders give royal titles to people who excel in their respective careers, and the title is recognized by the state, the title "sir" for men while "dame" if she is a woman and it put in front of their names, while Buginese Bone has hierarchical system was mention that different rank of job make different honorific and it used to respect and dignify someone’s status, this form used honorific lexemes such as tabe’, ndi’, iye’, puang, and petta cama’, beside in order to show respect in English utterances by immediately greeted by name, such as Paul, George, Clara and Jane because in English the name is more important than the title.

Abstract

This research aims to reveal the ability of 1st graders of SMAN 11 Enrekang in compiling verbal and nominal sentences using the simple present tense and the difficulties that occur when compiling verbal and nominal sentences using the simple present tense. The researcher used quantitative method by applying the Surface Strategy Taxonomy in analyzing the data. The results of this research indicating that there are four types of errors. The frequency and percentage based on the surface strategy taxonomy are 63.59% misformation, then 16.18% addition, 13.88% omission, and 6.35% misordering. Furthermore, there are three difficulties experienced by students in compiling verbal and nominal sentences using the simple present tense, 1) Students do not understand the grammatical system; 2) students just write down what comes to mind without following the grammar; and 3) students do not understand vocabulary. The teachers recommend practicing grammar rules, in the simple present tense for mistakes. In addition, other researchers can provide techniques to improve students' mastery of the simple present tense

Abstract

Background: Diabetic neuropathy is a condition that arises as a complication of diabetes mellitus and often causes pain in patient. Quercetin and its derivatives have antinociceptive activity, making them potential agents for relieving the pain associated with diabetic neuropathy. Objective: This study aims to analyze the interactions between quercetin and its eight derivatives with canonical transient receptor potential channels 6 (TRPC6) as protein target. Method: The TRPC6 structure (PDB ID: 6UZ8) was prepared and validated with redocked to native ligand R0D using Autodock 4.2.6, with the established grid box and grid center settings. The test compounds were then optimized and docked using the same grid box and grid center settings as in the validation process, followed by visualization and analysis of the docking results. Results: The compound with the best affinity for TRPC6 was tamarixetin, with a binding energy value of -3.27 kcal/mol, close to the binding energy value of the native ligand, which was -4.22 kcal/mol. The amino acid residues interacting with tamarixetin at the active site were 702-Asn, 705-Tyr, 706-Val, and 709-Gly. This indicates that tamarixetin and the native ligand bind to the same active site amino acids, resulting in a similar affinity to the native ligand in inhibiting TRPC6. Conclusion: A total of eight quercetin derivatives were predicted to have TRPC6 antagonistic activity against diabetic neuropathy, with tamarixetin exhibiting the highest affinity compared to the other quercetin derivatives.

Abstract

This paper explores the anthropomorphic elements in Beatrix Potter's Peter Rabbit and their role in reflecting Victorian societal values. Through the depiction of Peter wearing human-like attire, notably his blue jacket, and standing upright, Potter imbues the character with human qualities, making him relatable to young readers. This anthropomorphism serves to symbolize both the innocence and adventurous spirit of childhood, while highlighting the tension between curiosity and the moral lessons of obedience and responsibility. The garden, as a space of both adventure and danger, mirrors the Victorian ideal of childhood exploration within the confines of authority. Peter's journey—marked by disobedience, mischief, and eventual growth—illustrates the duality of childhood: innocence coupled with the need for guidance. By balancing exploration with consequences, Potter’s narrative conveys timeless moral lessons, making Peter Rabbit a relatable, enduring story for both children and adults that transcends its Victorian context. The story’s appeal lies in its ability to speak to universal themes of personal growth and the balance between freedom and discipline. Potter’s use of anthropomorphism, coupled with her nuanced portrayal of childhood, ensures that Peter Rabbit remains an essential piece of literature that continues to resonate across generations.

Abstract

Ecofeminism is an understanding of the relationship between women and the universe that approaches issues of environmental degradation and social injustice from the premise that how we treat nature and how we treat each other are inseparable. This research discusses the character of a woman in the novel How Beautiful We Were which aims to find out the depiction of the struggle of African women in protecting their environment. This research uses the theory of ecofeminism from Greta Gaard and Murphy with descriptive qualitative research methods and note- taking as an instrument. This research was conducted to add and give awareness to readers about the importance of preserving and protecting the environment around us. The results found in this novel that the female character named Thula fulfills the three aspects of women's struggle in the theory of ecofeminism. The researcher concluded that in this novel, the most visible struggle of women leads to the community, so that the movement carried out by the main character is able to realize that it is important to fight for and protect our nature from the threat of companies that come to destroy it

Abstract

This research explores the processes and underlying factors that lead to culture shock in the main character of the movie Queen (2014), employing Sverre Lysgaard's U-curve theory as the analytical framework. The U-curve model outlines various stages of adaptation that individuals undergo when exposed to a new culture. Through this lens, the study identifies six key phases experienced by the protagonist: before departure, arrival (Honeymoon), the onset of culture shock, feelings of discomfort and unhappiness, gradual adjustment, and eventual completion of the adaptation process. The analysis reveals that the main factors contributing to the character's culture shock include significant differences in cultural norms, unfamiliar food, lifestyle changes, and language barriers. Each of these elements presents unique challenges, which the character must navigate as she transitions into her new environment. This research not only highlights the emotional and psychological shifts during the adaptation process but also underscores the broader impact of intercultural encounters, offering a nuanced understanding of how cultural differences influence personal growth and adaptation in unfamiliar settings.
