Effectiveness of Yoga Therapy and Pranayama in Reducing Examination-associated Anxiety among (Tenth) 10th Standard Students in the Selected High Schools at Bangalore, India
Full text linkAnxiety is a human emotion that is a part of life and can often serve as a beneficial form of adrenaline, for instance, before giving a speech, taking an exam, or performing on stage. Anxiety levels vary from student to student, and only a small fraction of exam-anxious students ever receive adequate anxiety reduction training. However, it can drastically impact and affect functions or performance. There are methods to overcome nervousness and anxiety when they interfere with performance. An experimental research design was used in this study on 60, students of 10thstandard from the selected high schools in Bangalore, India This is an experimental research design study conducted on 60 10th-standard students selected from high schools in Bangalore, India. A modified anxiety rating scale was used to assess the level of examination anxiety among 10thstandard students. Pre-test- and post-test data were collected after 4 weeks of intervention on both the experimental and control group. Yoga and pranayama were given to the experimental group along with counselling, whereas only counselling was given to the control group. The results of this study showed that in the experimental group, the overall mean pre-test and post-test scores were 100.02 and 54.01, respectively, with a paired ‘t’ value of 11.60, which was above the table value of 2.7 at p≤0.01 level of significance. Whereas in the control group, the overall mean pretest and post-test mean score was 104.77 and 101.43 respectively with paired ‘t’ value of 0.82, which is not significant at p≤0.01 level of significance. Excessive exam anxiety can result in stress and may negatively affect performance. Yoga therapy may help individuals work with the physical, as well as the emotional tensions that either reduce anxiety. 
INVESTIGATION ON BEHAVIOR OF BUBBLES GENERATION IN A DROPLET IMPINGING ON A HEATING SURFACE
Full text linkCooling method in which fine water droplets are sprayed onto a high-temperature surface has been considered as a method that has a higher heat transfer coefficient than a cooling method in which cooling water is circulated over a high-temperature surface. The purpose of this study is to observe and clarify the mechanism of generation behaviors of bubbles in the center of droplet when a water droplet collided with a heating surface. A transparent sapphire was used as the heating surface in order to clearly catch the bubble which arises at the solid-liquid contact surface. Boiling behavior was photographed by a high-speed video camera from the backside direction of the surface. Bubbles’ fluctuation was measured in order to determine the behavior during boiling process. Also, two different heating surfaces were used to determine the effect of surface wettability. Alas, the sapphire heated surface pretreated with hydrogen peroxide plasma had better wettability and increased bubble point density than the original sapphire surface

The Knowledge, Attitude, and Practice on Human Papillomavirus (HPV) Vaccination and Pap Smear Screening is Low among Young Adult Women in Muar, Malaysia: a cross-sectional study
Full text linkCervical cancer is the third most common cancer among women in Malaysia. However, there is still a lack of research and information regarding the women\u27s knowledge, attitudes, and practices regarding the acceptance of Human papillomavirus (HPV) vaccination, and Papanicolaou (PAP) smear screening in the control program. The study was aimed to determine the knowledge of young adult women in Mukim Sungai Raya, Muar District, about the knowledge, attitudes and practices of HPV vaccination and Pap smear screening as a prevention of cervical cancer in Malaysia. The cross-sectional study was conducted using a self-filled questionnaire among young adult women aged 19-25 years old at Mukim Sungai Raya Muar. The participants were selected conveniently based on the list provided by Mukim’s Head. The study showed that 67.3% of respondents had low knowledge on HPV vaccination and Pap smear screening, 50.9% had a negative attitude toward it, whilst 47.7% had completed two doses of HPV vaccine, but only 9.3% had been performed Pap smear screening. The lower level of education was significantly associated with a lower level of knowledge (p= 0.025). There was no association between levels of knowledge with attitude. The knowledge, attitude and practice on HPV vaccination and Pap smear screening were found to be low among young adult women at Mukim Sungai Raya, Muar. The intensive health promotion program should be instituted among young women in the rural and sub-urban setting
Awareness, Knowledge and Attitudes Towards Safe Antibiotic Use among Outpatient Visitors at a Teaching Hospital in Malaysia
Full text linkIntroduction: Antimicrobial resistance has emerged as a significant issue largely due to the misuse of antibiotics in treating bacterial infections since their introduction. Misuse of antibiotics includes failure to finish the full course and prematurely stopping their antibiotic treatment after symptoms improve. Although antibiotics cannot be self-prescribed in Malaysia, misuse still occurs among consumers. Purpose: This study aimed to assess the level of awareness, knowledge and attitude (AKA) on safe antibiotic use among outpatient visitors of a teaching hospital in Pahang, Malaysia. The association between sociodemographic background and AKA score was also explored to identify the knowledge gap within various backgrounds. Methods: A total of 206 participants were recruited for this study. The participants were approached at several outpatient departments in a teaching hospital using convenient sampling from May until June 2022 and completed a set of validated questionnaires. The data were analysed using SPSS. Results: Only 35.4% of participants obtained a high score in knowledge, while the majority scored moderately. Among the 206 participants, 51.0% had poor awareness of safe antibiotic use. More than half of the participants (63.1%) exhibited a positive attitude towards antibiotic consumption. Education level and medical background were shown to be statistically significant to AKA scores. Conclusion: This study highlights that despite moderate knowledge and poor awareness of safe antibiotic use among hospital attendees, a positive attitude towards antibiotics was observed. It is essential to implement public educational campaigns that address knowledge gaps and misconceptions to improve antibiotic safety among the population
Diagnosing the Rare: Clinical Experience in Acardia Twin Recognition - A Case Report
Full text linkTwin Reversed Arterial Perfusion (TRAP) sequence or acardiac twin, is a rare condition in monochorionic twin pregnancies, presenting significant diagnostic and management challenges. Early detection of TRAP is crucial to improve foetal outcomes, particularly for the pump twin. We report the case of a 37-year-old gravida 5, para 3 + 1, who was initially misdiagnosed with a singleton pregnancy based on clinical and ultrasound examinations conducted at both primary and secondary health facilities. A marked discrepancy between the symphysiofundal height and ultrasound parameters later led to reassessment, revealing a twin pregnancy complicated by TRAP sequence. Radiofrequency ablation (RFA) was successfully performed on the acardiac twin at 28 weeks. The pregnancy ended at 30 weeks gestation with preterm birth, in which the pump twin was delivered alive while the acardiac twin was stillborn. This case highlights the importance of vigilant antenatal assessment, timely diagnosis, and intervention to optimise outcomes in TRAP sequence pregnancies
FAILURE MODE AND EFFECT ANALYSIS FOR MECHANICAL COMPONENT OF DIY 3D PRINTER
Full text linkFailure Mode and Effects Analysis (FMEA) is a widely used tool for identifying potential failure modes in a system, evaluating their effects, and implementing measures to mitigate or eliminate them. In the case of a DIY 3D printer, FMEA can be used to identify potential failure modes that could lead to sub-optimal performance or even complete system failure. The FMEA process involves identifying potential failure modes, determining their severity, likelihood of occurrence, and detectability, and then prioritizing them based on their risk priority number (RPN). This process can be used to identify potential failure modes in various aspects of the 3D printer system, including mechanical components. In the maritime sector, the use of 3D printers in replacing several main machinery parts is now seeking demand. There is no denying that using this technology in the industry has both benefits and drawbacks. Yet as time passes, this technology\u27s deficiencies continue to be corrected and it keeps growing. Understanding modern technologies like 3D printing is therefore highly beneficial. Knowing how well the printer is in excellent condition and locating the printer issue that will result in the machine being underpowered are some aims of the risk assessment. A risk analysis of printer failure is essential to prevent failure while running the printer. The printer\u27s durability will occasionally decrease, and it is simple to destroy the internal components by pushing them to perform harder than they can. Understanding the state of this printer is the primary goal of risk assessment or risk failure analysis. Hence, in this project, the mechanical components of DIY 3D printer failure risk assessment are conducted using FMEA
THE STUDY OF DIFFERENT SIZES OF DIY MODEL COMBUSTION CHAMBER
Full text linkAchieving perfect combustion plays a vital role in the operation of marine diesel engines, as it directly impacts the engine\u27s efficiency, performance, and emissions. Perfect combustion entails the complete burning of fuel, resulting in the production of carbon dioxide and water vapor. Optimization of engine performance, enhance fuel economy, and reduce emissions can be attained by adjusting the fuel injection system in response to pressure variations. To maximize performance and efficiency, careful attention must be given to the design and maintenance of both the combustion chamber and the fuel injection system in a diesel engine. The project aimed to illustrate the actual working pressure in the combustion chamber of an operational direct injection diesel engine. An injector tester was employed to showcase diverse pressure buildups on DIY model combustion chambers of varying sizes. A slowmotion camera was utilized to provide a detailed observation of the processes involved in spray formation and dispersion. The slowmotion footage served as a valuable visual aid, facilitating an understanding of how alterations in pressure and volume affect the atomization of fuel and the subsequent spray pattern. Mathematical approaches were employed to determine the chamber pressure buildup and the spray cone angle. An increase in pressure from 16.71Pa to 36.61Pa within the 150ml DIY model chamber resulted in a wider spray angle, whereas a decrease in pressure from 17.29Pa to 8.07Pa within the 200ml DIY model chamber led to a narrower spray angle
