The main objective of this paper is to probe the extent to which misinformation propagated through the different social media platforms contribute effectively in the process of directing, shaping and reshaping societal awareness of Saudis. In so doing, this paper attempts to delve into the relationship between linguistic misinformation and societal awareness, by exploring the perception of Saudis towards social media news, particularly misinformation and the extent to which this misinformation influences the social attitudes of Saudis in terms of various societal issues. Two main research questions are addressed in this study. First, to what extent does social media misinformation affect Saudis' awareness? Second, what are the linguistic manifestations of misinformation presented in the different social platforms? Two main findings have been recorded in this study: first, misinformation significantly contributes to the societal awareness of Saudis; and, second, however misinformation is linguistically manifested at the different levels of linguistic analysis, it is highly representative at the lexicalization level of language use.

Unity's Cinemachine, one of the game production technologies, can produce 3D images. However, since Cinemachine is a game production tool, video creators may find it difficult because the work process of Cinemachine is unfamiliar and complicated. However, it is necessary to learn new technologies for the future of video contents that will be advanced in the future. In order to understand Chinemachine as a video producer, I would like to embody the scene of the movie. We are going to produce a storyboard scene for storytelling in Cinemachine. We defined the workflow of Unity Cinemachine while directing the scene by creating a story, and also checked the advantages and cautions. I hope it will be an opportunity to enjoy using Unity Cinemachine, which is constantly evolving.

This study addresses the effectiveness of a VR model that is designed to relieve distress and improve communication during pediatric dental treatment for 3-9 year-old young patients. This is due to the challenging nature of the dental treatment for both young patients and pediatric dentists. The proposed model is designed to alleviate the unpleasant experience a young patient might go through during the dental treatment through providing a VR content to be displayed in on a head-mounted device during the treatment session. In addition, the model is designed to help decrease the frequent movement of the young patient during the dental treatment session by directing the patient's head to the immersive VR content. Furthermore, the model could solve the communication difficulties that might occur between pediatric dentists and young patients during the treatment session by showing live instructions related to adjusting body postures

With Unity creating footage is possible by using 3D motion, 2D motion, particular, and sound. Even post-production video editing is possible by combining the footage. In particular, Cinemachine, a suite of camera tools for Unity, that greatly affects screen layout and the flow of video images, can implement most of the functions of a physical camera. Visual aesthetics can be achieved through it. However, as it is a part of a game engine. Thus, the understanding of the game engine should come first. Also doubts may arise as to how similar it is to a physical camera. Accordingly, the purpose of this study is to examine the advantages and cautions of virtual cameras in Cinemachine, and explore the potential for development by implementing storytelling directly.

Ferroptosis is a novel mechanism of programmed cell death, characterized by intracellular iron overload, intensified lipid peroxidation, and abnormal accumulation of reactive oxygen species, which ultimately resulting in cell membrane impairment and demise. Research has revealed that cancer cells exhibit a greater demand for iron compared to normal cells, indicating a potential susceptibility of cancer cells to ferroptosis. Stomach and colorectal cancers are common gastrointestinal malignancies, and their elevated occurrence and mortality rates render them a global health concern. Despite significant advancements in medical treatments, certain unfavorable consequences and drug resistance persist. Consequently, directing attention towards the phenomenon of ferroptosis in gastric and colorectal cancers holds promise for enhancing therapeutic efficacy. This review aims to elucidate the intricate cellular metabolism associated with ferroptosis, encompassing lipid and amino acid metabolism, as well as iron metabolic processes. Furthermore, the significance of ferroptosis in the context of gastric and colorectal cancer is thoroughly examined and discussed.

The elementary stage is of great importance in establishing and supporting students during the beginning of their school life. Therefore, the current study aims to explore the Saudi teachers' perspectives about online learning and its effectiveness on some students' skills. The sample consisted of 250 male and female elementary teachers from different Saudi regions, and they responded to an online questionnaire consisting of both open and closed items to investigate their perspectives on online learning and face-to-face learning. The results showed a great perception and awareness among male and female teachers about the advantages and disadvantages of online learning. In addition, the results show that elementary teachers prefer face-to-face learning because it is the most stable and avoids many of the disadvantages mentioned for online learning. From this point of view, the study emphasizes the importance of integrating the two types of learning and directing teachers' professional development practices towards enhancing and developing their digital skills.

Zeolites with different structures were synthesized from the hydrothermal synthesis condition employing simple structure directing agent (SDA) containing piperidine moiety. The gel containing $1.0SiO_2$:0.9SDA:$0.062NaAlO_2$:0.217NaOH:$20H_2O$ was subject to hydrothermal synthesis at 413~453 K for 7 days. FER type zeolite was obtained at 433 K when piperidine was employed as SDA, whereas TON and MFI type zeolites were also obtained at 433 K when 2,6-dimethylpiperidine and 2,2,6,6-tetramethylpiperidine were used, respectively. Further increase of hydrothermal synthesis temperature to 453 K resulted in the formation of TON type zeolite when 2-mtheylpiperidine was used. The structural analysis of powder X ray diffraction pattern over FER type zeolite suggested that the SDA, piperidine interacted intimately with the zeolite where it located close to the framework.

This study ranked the degree to which flipped learning contributes to each learning area and, in contrast, to quantitatively examine how effectively these learning methods are used in flipped learning, had four-year university computer majors receive flipped learning. Existing flipped learning experiments have proven effectiveness, while there are also negative effects on effectiveness, which has led to a lot of debate. Effective experiments and classes therefore require more research and an accurate understanding of flipped learning. Analysis of the 123 samples recruited shows that flipped learning contributes to learning is in order of self-directing, collaboration, watching videos, and learning by teachers. Regression analysis of the degree to which learning method affects flipped learning effectiveness resulted in order of self-directed learning, lecture videos, and collaborative learning. This shows that flipped learning not only has the greatest influence on self-directed learning, but also self-directed learning has the greatest influence on flipped learning. It can also see that a collaborative learning and the role of video to prior learning tool is important. Through this study, we hope to understand flipped learning correctly and set learning methods and achievement goals. It is necessary to analyze the interaction between flipped learning and subdivided classroom activities.

Structure directing agent(SDA) containing piperidine moiety such as piperidine(PI), 2-methylpiperidine (MPI), 2,6-dimethylpiperidine(DMPI) and 2,2,6,6,-tetramethylpiperidine(TMPI), respectively has been utilized to synthesize aluminophosphate zeolite using hydrothermal method. The gel composition was $1.0Al_2O_3:1.0P_2O_5:0.76SDA:45H_2O$ and the hydrothermal heating was performed in an oven at 443 K and for 7 days at static mode. The obtained zeolitic material contained a lamellar structure when PI was used as the SDA. With a progressive increase of the SDA size, various structures of aluminophosphate including AlPO-5 of AFI structure were obtained. The aluminophosphate of SAS structure was formed when the largest TMPI was utilized as the SDA, which was confirmed by the Rietveld refinement. The result of $^{27}Al$ and $^{31}P$ MAS NMR of the sample suggested that Al and P were incorporated into the framework of the aluminophosphate.
