Abstract. The air flow velocity is one of many factor which should be considered in building a skyscraper. This is because the air flow velocity can affect the comfort of house room. The method which is used to solve the air flow analysis is a finite volume withusing Quadratic Upwind Interpolation Convective Kinematics (QUICK) discretization technique. Finite volume method is used to obtain a mathematical model of air flow velocity and QUICK is used to discretize it such that it will yield a linier equation system in a matrix of size (mn)×(mn). To simulate the air flow analysis is used Matlab and Fluent softwares. The result show that if the barrier is higher the air flow velocity will be decreased and if the distance of barrier is longerthe air flow velocity will be increased. It can be conclude that this analysis can be applied to have a comfort house room. Key Words : air flow velocity,mathematic model, finite volume method,QUICK

Abstract

Modern society has the view that hedonism is a lifestyle that only emphasizes pleasure such as shopping for luxury goods and eating expensive food. This is contrary to the simple lifestyle proposed by Epicureans. Epicureans distinguish between natural desires that are needed (such as eating) and natural desires that are allowed (such as delicious food), and vain desires (such as wealth) (K. Bertens, 2000). Therefore, hedonism does not always have to prioritize luxury but can improve the quality of enjoyment itself. Evolving the issue of flexing in society is often done by the youth as a negative stigma yet it could be positive if it is seen from a different angle. This study also identifies the influence of hedonism on the main character's life. In this research, the researcher used the qualitative method to analyze the data as it is concerned with the subjective assessment of attitudes, opinions, and behavior. The finding of this research was that natural desires are allowed to have the effect of being able to (1) enjoy life more, (2) have a high social spirit, and (3) be wise in dealing with problems. The impact of vain desires tends to be (1) anti-social, (2) excessive consumptive behavior, and (3) unsatisfactory

Abstract

Highlight: Meningioma, the most common primary brain tumor, is typically found in women aged 40-49 years old. Meningiomas can show distinctive characteristics on clinical, radiological, and histopathological examinations. There were significant differences in histopathological grading between male and female patients, as well as between homogenous and heterogenous contrast enhancement.   ABSTRACT Introduction: Meningioma is an intracranial extracranial tumor that arises from arachnoid cells. It is reported to be the most common primary brain tumor (39%). Meningioma is diagnosed based on clinical and radiological findings, but a definitive diagnosis requires histopathology examination. However, the clinical, radiological, and histopathological profile of meningioma is rarely studied in Indonesia. Objective: This study aimed to identify the clinical, radiological, and histopathological profile of meningioma patients at Dr. Soetomo General Academic Hospital Surabaya from 2017 to 2021. Methods: This was a retrospective observational study with a cross-sectional design using secondary data collected from electronic medical records at Dr. Soetomo General Academic Hospital Surabaya in 2017-2021. Results: A total of 256 patients were included in this study. The majority of the patients in this study were female (83.98%), aged 40-49 years old (43.36%), and mostly had the clinical symptom of headache (35.94%). Meningiomas were mostly WHO grade I (85.16%), with a transitional subtype (44.92). Based on the Kruskal-Wallis test, there were differences in histopathological grading between male and female patients (p = 0.000), as well as between homogenous and heterogenous tumor enhancement (p = 0.027). However, there were no differences in histopathological grading between the dural tail findings (p = 0.181) and hyperostosis findings (p = 0.135). Conclusion: Meningioma was found to be more common in females than in males, with the peak occurring in 40-49 years old. The most prevalent clinical symptom was headache, and convexity was the most common location for these tumors, most of which were larger than 3 cm. The majority of meningiomas were WHO grade I with transitional subtype.

Abstract

Introduction: It is necessary to develop alternative antidiabetic therapies that are safer and more affordable to overcome the high prevalence of diabetes mellitus in Indonesia. Ajwa dates (Phoenix dactylifera) have a high flavonoid content; hence, this study aimed to investigate their effect on streptozotocin-induced diabetes mellitus mice by examining the number of beta cells and the islets of Langerhans. Methods: Twenty-five mice were divided into five groups: a negative control group (K1), a positive control group (K2), and three treatment groups (P1, P2, and P3). The K2, P1, P2, and P3 groups were induced by 100 mg/kg bw of streptozotocin. Additionally, the P1, P2, and P3 groups received oral treatment using ajwa date methanol extract at different doses of 3, 5, and 7 g/kg bw, respectively. The treatment was administered daily for four weeks. The initial analysis included the homogeneity test and the Shapiro-Wilk test. As the data were non-normally distributed, the analysis proceeded with the Kruskal-Wallis test (p<0.05). Results: The comparative analysis revealed significant differences in the number of beta cells among the groups, with a notable decrease observed in the K2 group and an increase in each treatment group. The measurement of the islets of Langerhans exhibited significant differences among the groups, with p=0.001.  Conclusion: The administration of ajwa date methanol extract can affect the number of beta cells and the islets of Langerhans in mice with diabetes mellitus.   Highlights: 1. This original study examined the antioxidant compounds derived from naturally sourced ajwa date (Phoenix dactylifera) extract. 2. Ajwa date extract has the potential to protect against histological damage, specifically to beta cells and pancreatic islets, in mice induced by streptozotocin.

The widespread incidence of DM leads to costly treatments and often results in undesirable side effects. Methanol extract of Ajwa date fruit can effectively lower blood glucose levels in diabetic mice at specific optimal doses.   Abstract Introduction: High diabetes mellitus (DM) cases result in costly medical expenses. Ajwa date fruit contains triterpenoids, carbohydrates, and flavonoids believed to lower blood glucose, which requires research validation using methanol extract on streptozotocin (STZ)-induced mice. This study aimed to determine the effect of methanol extract of Ajwa dates with several dose levels, namely 3 g/WB, 5 g/WB, and 7 g/WB, given orally to mice induced by STZ. Methods: This study utilized a randomized pre- and post-test control group design to assess Ajwa date fruit methanol extract effects on blood glucose in Swiss-Webster mice (Mus musculus). The mice were divided into four groups: Group K (6 mice without date extract intervention), P1 (6 mice with 3 g/WB/day oral dose date extract intervention), P2 (7 mice with 5 g/WB/day oral dose date extract intervention), and P3 (7 mice with 7 g/WB/day oral dose date extract intervention) and were induced with 100 mg/WB streptozotocin. Administered daily for three weeks, Ajwa dates fruit extract showed varying impacts. Weekly blood glucose measurements and analysis of variance (ANOVA) in the International Business Machines Corporation (IBM) Statistical Package for the Social Sciences (SPSS) version 27.0 disclosed significant group differences, with a p<0.05 considered statistically significant. Results: Post-test blood glucose measurements in the third week showed a significant difference (p=0.017), with an optimal reduction in P3 (7 mice with 7 g/WB/day oral dose date extract intervention). Conclusion: In the third week, Ajwa dates fruit extract, at an optimal 7 g/WB dose, effectively reduced blood glucose levels via flavonoid hypoglycemic mechanisms.

Abstract

Highlights: The younger age and shorter duration of misalignment are significant predictors of success in horizontal strabismus surgery. Younger patients tend to have higher success rates, and shorter durations of misalignment correlate with better surgical outcomes. Despite variations in population and surgical methods, the overall success rate of 82.3% for horizontal strabismus surgeries aligns with previous studies. This consistency underscores the reliability of surgical outcomes in different settings.   Abstract Introduction: Strabismus is an eye disorder characterized by misalignment of the eyes, which can occur in individuals of any age. This study explored the surgical outcomes of horizontal strabismus correction in patients, aiming to provide insights into the factors influencing success. Methods: A prospective study was conducted with 17 patients (n=17) who underwent surgery at Dr. Soetomo General Academic Hospital, Surabaya, Indonesia. Preoperative factors, including age, duration of misalignment, and preoperative angle of strabismus, were analyzed for their impact on surgical success. The International Business Machines Corporation (IBM) Statistical Package for the Social Sciences (SPSS) for Macintosh version 27.0 was used for data analysis. Results: This study reviewed the medical records of 17 research samples (n=17). A significant change in the median angle of deviation prism diopters (PD) preoperatively was indicated by the median Postoperative Deviation (PD) (p<0.001). A significant difference in median age at surgery was observed between successful and unsuccessful cases (p=0.035), with younger individuals exhibiting a higher success rate. The duration of misalignment emerged as a crucial factor, with a shorter duration correlating positively with a higher probability of surgical success (p<0.001). Notably, successful outcomes were achieved by all children (100%), suggesting a potential trend indicating age as a predictor of success. While the preoperative angle of strabismus did not significantly impact success, a trend emerged (p=1), indicating a potential threshold effect for more significant angles. Conclusion: Knowing the significance of age and duration of misalignment on the success rate of strabismus surgery allows for enhanced preoperative assessments, optimized timing of surgery, and developed predictive models to assist in clinical decision-making, ultimately leading to more efficient and successful surgical outcomes.
