Appendiceal goblet cell adenocarcinoma (GCA) is an amphicrine tumor composed of goblet-like, and variable numbers of endocrine and Paneth-like cells, typically arranged as tubules resembling intestinal crypts. As a rare cancer, the characteristics of and appropriate treatment strategy for GCA have not been fully elucidated. Here, we describe a case of an appendiceal GCA detected during sigmoidectomy for synchronous sigmoid colon adenocarcinoma and discuss whether appendiceal GCA coexisted incidentally. A 78-year-old woman was referred to our institution due to severe anemia. Colonoscopy and computed tomography revealed circumferential sigmoid colon cancer and a primary or metastasized ovarian tumor. We performed a laparoscopic sigmoidectomy and bilateral adnexectomy. The appendix appeared infiltrative and indurated, and appendectomy was performed. Immunohistochemistry revealed sigmoid colon adenocarcinoma and appendiceal GCA with ovarian metastasis. GCAs should be considered when ovarian tumors are detected with other abdominal malignancies.

Authors: Rakya Ziad H.
Published: December 2023

The utilisation of Artificial Intelligence (AI) technology has caused remarkable changes that have taken place in the educational landscape. Through the integration of AI in online learning systems, an entirely new educational experience has been introduced, altering the ways learners and educators can interact. The emergence and evolution of AI technology have increased efficiency and productivity, enhancing teaching and learning outcomes. AI in online learning provides a distinct advantage by providing real-time feedback to learners. Traditional learning environments often suffer from the limitation of delayed feedback, impeding learners’ progress and demotivating them. However, AI-powered online learning systems excel in delivering immediate feedback to learners, enabling them to promptly identify and rectify mistakes and enhance their performance in real-time. This timely feedback fosters a supportive learning environment that encourages learners to engage in the learning process actively. The research by Vanlehn, Lynch, Schulze, Shapiro, Shelby, Taylor et al. (2005) on the Andes physics tutoring system serves as a valuable resource for understanding the lessons learned from utilising AI to support learner-instructor interaction. In contrast to traditional learning environments that offer delayed feedback, impeding the progress of learners and possibly dampening their motivation, AI-powered online learning systems provide real-time feedback. With real-time feedback, learners can instantly correct mistakes and improve their performance, thereby advancing their learning outcomes (Zhou & Mei, 2021). This literature review explores the impact of AI on learner-instructor interaction in online learning environments. The review considers how AI technology enhances and diversifies the learning process, focusing on personalised learning, real-time feedback provision, and content delivery.

FLIGHT DELAY PREDICTION BASED ON AVIATION BIG DATA AND MACHINE LEARNING
Authors:   Sreyas Institute of Engineering and Technology, raj Mr. S . Prudhvi
Published: December 2023

Accurate flight delay prediction is fundamental to establish the more efficient airline business. Recent studies have been focused on applying machine learning methods to predict the flight delay. Most of the previous prediction methods are conducted in a single route or airport. This paper explores a broader scope of factors which may potentially influence the flight delay, and compares several machine learning-based models in designed generalized flight delay prediction tasks. To build a dataset for the proposed scheme, automatic dependent surveillance broadcast (ADS-B) messages are received, pre-processed, and integrated with other information such as weather condition, flight schedule, and airport information. The designed prediction tasks contain different classification tasks and a regression task. Experimental results show that long short-term memory (LSTM) is capable of handling the obtained aviation sequence data, but over fitting problem occurs in our limited dataset. Compared with the previous schemes, the proposed random forest-based model can obtain higher prediction accuracy (90.2% for the binary classification) and can overcome the over fitting problem.

Enhancing Language Learning through PBL in an Aviation Engineering Class
Authors: Alsayegh Fatma K.
Published: December 2023

English for specific purposes is a field of teaching and learning that focuses on English language skills in context. It bridges the gap between general language knowledge and specific communication skills to enable students to meet the demands of their future professional field. For instance, aviation maintenance engineering requires the knowledge of highly specialized terminology. By providing appropriate and relevant linguistic tools, ESP enables aviation students to successfully perform job-related tasks and become more professionally competent within the aviation industry.

While ESP has a role in improving language learning, the student’s experience can be further enhanced by incorporating Project-Based Learning into the curriculum to make learning more meaningful through inquiry-driven, task-based, and problem-solving paradigms. One key advantage of ESP in this regard is its adaptability, which means it can be adapted into a functional course. According to Dudley-Evans and St Johns (1998): “ESP was, for example, very influential in showing how a communicative language curriculum could be turned into either a functional-notional syllabus or a task-based syllabus” (Dudley-Evans & St Johns, 1998).

The purpose of this article is to demonstrate a PBL method used in an ESP class aimed at aircraft maintenance engineers. The project involves students assembling a model aircraft jet engine. The goal of the project is to help students develop adequate knowledge about aircraft jet engines by acquainting them with the names and functions of the engine’s parts and also teaching them about its complex operation. Moreover, the project trains students on how to log their in-class activities into a weekly log that tracks their progress. At the end of the project, students reflect on their experience by completing a questionnaire that evaluates the outcomes of their learning. This helps the instructor assess the effectiveness of the project on the student’s language learning.

Published: December 2023

Evidence-based practice in psychology (EBPP) improves public health and makes it easier for psychologists to do their jobs well by using case formulation, intervention, and therapeutic relationship principles that have been shown to work in the real world. The utilization of evidence-based practice in the field of psychology has been widely regarded as the most effective approach for researchers and practitioners to incorporate current data into their therapeutic practice and decision-making processes. The objective of this study was to investigate attitudes towards EBPP and assess the level of exposure to evidence-based practice and evidence-based therapies in the corresponding training program among students. A cohort of 250 undergraduate students pursuing a degree in psychology were enlisted to participate in the survey. The research employed quantitative methodologies, specifically one-way ANOVA, Pearson correlation, and regression analysis, to examine and interpret the collected data. The favorable influence of students' judgments of the sufficiency of training in different components of clinical expertise and exposure to evidence-based practice (EBP) and evidence-based treatments (EBTs) in their respective training program can be observed in students' experiences and attitudes towards EBP in psychology. The findings derived from the present study provide compelling evidence supporting the imperative of implementing educational interventions aimed at enhancing the research knowledge and skills of psychology students, as well as their ability to effectively utilize research in their academic pursuits.

Authors: Luo Xiaobin , Jaidi Junainah , Nipo Debbra Toria
Published: December 2023

Environmental accounting is not only a more comprehensive and effective accounting model but also a more beneficial monitoring model for ecological protection and social development. Environmental accounting enables companies to develop economic benefits while protecting and managing the environment and to assume corresponding social responsibilities and obligations. Based on the importance of environmental regulation, this study attempts to evaluate the role of environmental regulatory tools in corporate environmental information disclosure using the Environmental Information Disclosure Index (EIDI) as a proxy variable. The regression analysis conducted on a panel dataset encompassing all A-share listed companies in the Shanghai and Shenzhen stock markets from 2007 to 2018 reveals a significant relationship between environmental regulatory tools and EIDI. Specifically, the Control command type, Public Participation Type, and Voluntary action-oriented Type have a positive and significant influence on corporate environmental information disclosure, whereas the Market Incentive Type has a negative and significant influence. This evidence suggests that the reasonable use of environmental regulatory tools is an important means of improving the quality of corporate environmental information disclosure.

Authors: Yen Wendy Teoh Ming , Yen Yuan Yee , Choy Chong Siong , Nee Tee Win , Ming-Li Teoh
Published: December 2023

One of the main reasons for the low employment rate of Malaysian graduates is a lack of skills. A substantial number of employers have expressed dissatisfaction with the quality of graduates, claiming that they lack the necessary skills required for successful employment. This research aims to investigate the perceptions of employers on the importance and level of satisfaction with the employability skills of graduates and subsequently examine the gap between them (level of importance and satisfaction). The survey included 63 employers from the manufacturing industry, and the data were analyzed. The results suggest that employers viewed all eight skills, such as English communication skills, thinking skills, positive attitude and teamwork, work planning skills, work discipline, self-motivation, and technology skills, as essential employability skills. However, the gap analysis reveals that they were dissatisfied with the skills possessed by the graduates, indicating that the skills of the graduates fell short of their expectations, which is consistent with their dissatisfaction. The highest differences between satisfaction and expectation arise from English communication skills and thinking skills, followed by self-motivation, a positive attitude, teamwork, work planning skills, technology skills, and work discipline skills. This study provides important insights for graduates, higher education institutions, and policymakers in Malaysia, as well as in countries facing the issue of the low employability of graduates.

Phytochemical analysis of the extracts revealed the presence of phenols, tannins, saponins, glycosides, phytosterols, flavonoids, and terpenoids. Furthermore, the contents of phenolics, flavonoids, proanthocyanidins, and anthocyanins in the fruit extracts were quantified. The quantitative analysis of total phenolic content of extracts revealved that hydromethanolic extract contains higher quantity of phenolics, flavonoids, proanthocyanidins, and anthocyanins in comparision to the ethylacetate extract. These findings support the observation that hydro-methanolic extract of N. cadamba fruits exhibited superior anthelmintic activity compared to the ethyl acetate extract because polyphenolic compounds are well established for their anthelmintic activity.

In the last decade, the use of microbial activity has become increasingly widespread with the knowledge of the negative impact of providing inorganic fertilizer inputs on the cultivation of feed crops. A study was carried out to examine the effect of PGPR application from various host plants on increasing the yield of forage Asystasia gangetica (L.) subsp. Micrantha. The research was a pot experiment designed with a completely randomized design (CRD). The research began with identifying PGPR causes from various host plants, then applied to A. gangetica. The variables observed in this study were: the presence and population of PGPR on PGPR leader of Bambusa vulgaris Schrad, Mimosa pudica, Paspalum notatum and Eleusin indica grass plants, growth and yield of A. gangetica forage plants. The results showed that the highest number of non-symbiotic bacteria was found in PGPR from host plant roots E. indica as much as 1.1x106 cfu/ml, while the highest number of symbiotic bacteria was found in M. pudica host plant roots. The most TPC was found in the roots of the host E. indica as much as 6.4x105 cfu/ml, while the highest P bacteria were found in the roots of the host plants E. indica and M. pudica each with 3.4x105 cfu/ml. It was concluded that the highest forage yield of A. gangetica was obtained from the application of PGPR seeds E. indica and M. pudica respectively at 21.52 and 21.06 g plant-1.

Introduction: Sleep is essential for the quality of life and has fundamental functions for the functioning of the body. Its deprivation has negative consequences on body homeostasis and cognition. Sleep deprivation can become a risk factor for several diseases. There are deficiencies in the undergraduate medical curriculum regarding knowledge about sleep health, leading to underdiagnosis and undertreatment for patients. In addition to having consequences on sleep for doctoral students and physicians, thus affecting their health and professional performance.
Objective: To assess whether the physician’s perception of knowledge about sleep acquired during graduation interferes with the promotion of sleep health in the personal and professional spheres.
Methods: Observational study with a quantitative approach and a cross-sectional approach using a digital form. Physicians and interns were part of the study. The questionnaire had the following stages: epidemiology; subjective assessment of knowledge about sleep health; application of knowledge in professional and personal life; assessment of sleep quality using the Pittsburgh Sleep Quality Index (PSQI).
Results: The sample consisted of 103 participants. Most agreed to have acquired knowledge about sleep health during graduation. During the anamnesis, sleep was the least asked topic. The most reported measures that were positive to sleep hygiene were sleeping in a suitable environment and practicing physical exercises. The unfavorable ones were the use of electronics in the bedroom. There was no significant difference between year and level of training in relation to sleep quality. The most altered components of the index were daytime disorders and use of sleeping pills.
Conclusion: The importance of sleep health is well established, but sleep quality among physicians and interns is poor. Therefore, future changes in teaching, performance and research are necessary

Introduction: The COVID-19 pandemic had a significant impact on medical education, including the training of residents, affecting in-person teaching and leading institutions to adopt distance learning methods.
Objective: To evaluate the perception of residents in gynecology and obstetrics regarding the impact of the pandemic on their learning, identifying their safety when providing care and seeking to investigate whether residents would consider extending their residency.
Methods: A questionnaire with closed questions and responses on a Likert scale was used, addressing different aspects of medical residency during the pandemic to meet the objectives.
Results: Of the 71 residents, the majority were women (74.65%). Data analysis revealed that surgical practice was affected for the majority of them (85.92%), with the postponement of elective operations in gynecology (97.18%). Regarding practical learning, 42.25% considered it to be partially satisfactory, while 14.08% considered it unsatisfactory. In the theoretical field, residents’ perception was better, with 43.66% considering the learning satisfactory and 47.89% partially so. The pandemic partially affected medical residency for the majority of residents (85.92%), and alternatives were adopted to replace the lack of theoretical classes and practical activities.
Conclusion: The pandemic had a negative effect on medical education and resident training. The interruption of face-to-face activities affected both practical and theoretical learning

Introduction: Serrated lesions are considered precursors of colorectal adenocarcinomas. Studying them in their initial phases is important when thinking about cancer prevention, when they are hyperplastic lesions, or sessile serrated lesions.
Objective: To carry out an integrative review of the literature to compare the endoscopic and histopathological characteristics in the initial phases of the disease, with the intention to help understand colorectal cancer.
Methods: Integrative literature review based on existing analysis material on the digital platforms SciELO – Scientific Electronic Library Online, Google Scholar, Pubmed and Scopus. The beginning was the search with the following descriptors: “serrated sessile lesions, colorectal carcinoma, superficial lesions”, with AND or OR search, considering the title and/or abstract , and subsequently including only those with the highest correlation for reading the full texts.
Results: 39 articles were included.
Conclusion: The majority of superficially elevated serrated lesions measuring more than 5 mm and resected by colonoscopies are hyperplastic. They occur throughout the colon and rectum, while the serrated sessiles are preferentially located in the proximal colon. Hyperplastic ones generally do not present dysplasias and sessile serrated ones can have them intensely.

Introduction: The Charlson comorbidities index (CCI) assesses a person’s chances of survival over the next 10 years. In systemic lupus erythematosus (SLE), multiple comorbidities and complications affect patient survival.
Objetive: Analize the variables that influence the CCI of a group of females with SLE.
Methods: Retrospective study of medical records of 100 lupus patients for CCI, clinical, epidemiological and serological variables.
Results: No epidemiological variable interfered in CCI. Regarding clinical manifestations, patients with glomerulonephritis had a worse CCI than those without (p<0.0001) and those with central nervous system manifestations had a tendency to worse CCI (p=0.09). Patients with anti-Ro antibodies (p=0.02) and rheumatoid factor or RF (p=0.002) were associated with a lower CCI.
Conclusions: The presence of glomerulonephritis is associated with lower survival and of the anti-Ro and RF antibodies with longer survival in SLE.
Experiential Mobile Learning: QR Code Driven Strategy in Teaching Thermodynamics in Science 12
Authors: Serrano Arman
Published: December 2023

The purpose of this study was to examine whether QR code driven strategy would be effective in teaching thermodynamics in science 12. Experimental design was used to test the effectiveness of the strategy. Further, pretest-post- test design was employed wherein one section from grade 12 STEM strand was exposed to the intervention while the other section was exposed to traditional approach. Both groups took the same pretest-post-test which was composed of 50 multiple choice questions. The test questionnaire used was validated using Zipgrade application to determine the discrimination and difficulty index. Moreover, test scores were subjected to Cronbach’s Alpha for reliability test. Weighted mean was computed to describe the test scores of both controlled and experimental groups. T-test of difference between means of independent samples were used to determine the difference between the means of two groups and were tested at 0.05 level of significance. Results revealed that the two groups under study did not differ significantly in their pretest, which means that the students’ knowledge before the intervention were about at the same level. In contrast, based on the statistical analysis, the t-test significantly differentiated the two groups in favor of the experimental group, which registered higher means in the posttest.  This means that after the learning units using the QR code driven strategy, the experimental group was greatly improved in the posttest. Together, these findings also suggest that the two groups exhibited significant difference in their pretest and posttest but the QR code driven strategy effects to be predominant.
