Quantitative Raman Spectroscopic Determination of the Composition, Pressure, and Density of CO2-CH4 Gas Mixtures
Authors: Chen Ying , Chou I-Ming
Published: September 2022

The Raman spectra for pure CO2 and CH4 gases and their ten gas mixtures were collected at pressures and temperatures ranging from 2 MPa to 40 MPa and room temperature (∼24°C) to 300°C, respectively. A systematic analysis was carried out to establish a methodology for the quantitative determination of the composition, pressure, and density of CO2-CH4 mixtures. The shift in the peak position of the υ1 band for CH4 was sufficiently large to enable the accurate determination of the pressure of pure CH4 and CH4-dominated fluids (>50 mol% CH4). An equation representing the observed relationship of the peak position of the υ1 band of CH4, density, and composition was developed to calculate the density of CO2-CH4 mixtures. The Raman quantification factor F (CH4)/F (CO2) was demonstrated to be near a constant value of 5.048 ± 0.4 and was used to determine the CH4 to CO2 molar ratio in an unknown CO2-CH4‐bearing fluid with high internal pressure (>10 MPa) based on the Raman peak area ratio. The effect of temperature on the variation in Raman spectral parameters was also investigated at temperatures up to 300°C. The results showed that the effect of temperature must be considered when Raman spectral parameters are used to calculate the pressure, density, and composition of CO2-CH4 gas mixtures. Raman spectroscopic analysis results obtained for six samples prepared in fused silica capillary capsules were validated by comparison with the results obtained from microthermometry measurements.

Authors: Feng Aiping , Guo Wanliang , Jia Yong
Published: September 2022

According to relevant data, the morbidity and mortality of strokes in China remain high. Without effective treatment, stroke morbidity and mortality will continue to rise, which may become the second leading disease in the world. With the nonstop advancement and improvement of clinical innovation in China, the death pace of stroke patients has dropped altogether. After clinical treatment, the patient actually showed a progression of sequelae, which made it challenging to work on the personal satisfaction of the patient. The purpose for this paper was to concentrate on the impact of medical image fusion in the treatment of poststroke appendage brokenness with TCM needle therapy. The related concepts of medical image fusion and the meaning of acupuncture and moxibustion in traditional Chinese medicine, stroke, and limb dysfunction were introduced. In this study, acupuncture and moxibustion were analyzed to explore the therapeutic effect of this type of therapy on upper extremity dysfunction caused by phlegm and blood stasis blocking collaterals and to provide a scientific method for the treatment and efficacy judgment of upper extremity motor dysfunction after stroke. Before the treatment measures were taken, there was no significant difference in the general data and all index scores between the two groups (P > 0.05), and there was no significant difference in the baseline data, reflecting high balance and comparability. In the following 3 months of treatment, the FMA score, NIHSS score, BI list, and VAS score of the two groups of patients were essentially not quite the same as those before treatment (P < 0.05). When treatment, there was a huge contrast between the trial group and the control group (P < 0.05). The finish of the trial in this paper is that needle therapy joined with pricking and measuring can essentially work on the engine capability of stroke patients with furthest point brokenness brought about by mucus and blood balance impeding securities.

In this work, the zinc/cobalt‐based zeolite imidazolate frameworks ((Co/Zn)ZIFs) were synthesized with the solvothermal method. The obtained material was characterized by utilizing scanning electron microscopy (SEM), X‐ray diffraction (XRD), UV‐Vis diffusive reflectance spectroscopy, and nitrogen adsorption‐desorption isotherms. XRD and SEM analyses show that (Co/Zn)ZIFs are composed of nanocrystals with polyhedral shapes of around 50–100 nm and belong to the I‐43m space group as those of ZIF‐8 and ZIF‐67. Optical studies demonstrate a red shift in the absorbance spectrum of (Co/Zn)ZIFs compared with individual components of ZIF‐67 or ZIF‐8. (Co/Zn)ZIF composite was utilized as photocatalytic material to treat a model aqueous solution containing rhodamine B and bacteria. It was found that (Co/Zn)ZIFs could simultaneously degrade rhodamine B and inhibit bacteria (E. coli and S. aureus). The manufactured composite could catalyze the mineralization of rhodamine B and also exhibited good antibacterial activity against Gram‐negative E. coli (93.32% inhibition rate) and Gram‐positive S. aureus (90.86% inhibition rate) in the visible‐light region within four hours of irradiation. Gram‐negative bacteria were more resistant to (Co/Zn)ZIFs than Gram‐positive bacteria. (Co/Zn)ZIFs can be used as light‐driven catalysts for water and environmental detoxification from organic compounds like dyes and bacteria.

Objective. To study the effect of dexmedetomidine on cognitive function in rats with cognitive impairment after partial hepatectomy and its mechanism. Methods. 60 SD rats were randomly divided into 4 groups (

n
=
15

): blank control group (CG group), sham operation group (Sham group), cognitive impairment model group (POCD group), and dexmedetomidine + cognitive impairment model group (DEX group). Rats in the POCD group underwent left lobe hepatectomy and intraperitoneal injection of the same amount of normal saline after resuscitation. Rats in the DEX group underwent left lobe hepatectomy and intraperitoneal injection of dexmedetomidine 50 μg/kg. Group CG was not operated on and the same amount of normal saline was injected intraperitoneally. In the Sham group, liver resection was not allowed after the abdominal incision, and normal saline was injected intraperitoneally. Rats were injected every 24 hours for 5 consecutive days. Morris water maze (MWM) were used to evaluate the effects of dexmedetomidine on learning and memory ability of POCD rats. TUNEL method was used to detect apoptotic neurons in the hippocampus. INOS, Arg-1, IL-6, and TNF-αexpression levels were detected. Western blot detects the expression level of TNF-α, Bcl-2, and NF-κB protein. Result. Compared with the CG group, the escape latency of the other three groups was prolonged on the 5th day after the operation, and the number of crossing the platform was reduced. Compared with the Sham group, the escape latency of the POCD group and DEX group was significantly prolonged, and the number of crossing the platform was significantly reduced on day 5 (

P
<
0.05

). Compared with the POCD group, the DEX group shortened the escape latency and increased the number of crossing the platform on the 5th day (

P
<
0.05

). It shows that the spatial learning and memory function of rats has been restored to a certain extent.The number of iNOS and Arg-1 positive cells in the POCD group and DEX group was higher than that in the control group, and the number of Arg-1 positive cells in the DEX group was higher than that in the POCD group (

P
<
0.05

). Western blot results the expression of Bcl-2 and NF-κB protein in POCD group, and DEX group was higher than that of the sham group (

P
<
0.05

). The expression of Bcl-2 and NF-κB protein was the most in POCD group. The expression of Bcl-2 and NF-κB protein in DEX group was lower than that in POCD group (

P
<
0.05

). Conclusion. Behavioral results showed that the learning and cognitive ability of POCD model rats after hepatectomy was impaired, and inflammatory factors and activated microglia were found in the hippocampus of POCD rats. Dexmedetomidine may improve the brain function of POCD rats by inhibiting neuronal apoptosis,partly through NF-κB apoptosis pathway.

A Review on Thermal Imaging-Based Breast Cancer Detection Using Deep Learning
Authors: Tsietso Dennies , Yahya Abid , Samikannu Ravi
Published: September 2022

Breast cancer is the most common form of cancer in women. Its aggressive nature has made it one of the chief factors of high female mortality. Therefore, this has motivated research to achieve early diagnosis since it is the best strategy for patient survival. Currently, mammography is the gold standard for detecting breast cancer. However, it is expensive, unsuitable for dense breasts, and an invasive process that exposes the patient to radiation. Infrared thermography is gaining popularity as a screening modality for the early detection of breast cancer. It is a noninvasive and cost-effective modality that allows health practitioners to observe the temperature profile of the breast region for signs of cancerous tumors. Deep learning has emerged as a powerful computational tool for the early detection of breast cancer in radiology. As such, this study presents a review that shows existing work on deep learning-based Computer-aided Diagnosis (CADx) systems for breast cancer detection. In the same context, it reflects on classification utilizing breast thermograms. It first provides an overview of infrared thermography, details on available breast thermogram datasets, and then segmentation techniques applied to these thermograms. We also provide a brief overview of deep neural networks. Finally, it reviews works adopting Deep Neural Networks (DNNs) for breast thermogram classification.

CAMELYON 17 Challenge: A Comparison of Traditional Machine Learning (SVM) with the Deep Learning Method
Authors: Sun Tianbo , Meng Tong , Liu Yutong
Published: September 2022

The pathologist’s diagnosis is crucial in identifying and categorizing pathological cancer sections, as well as in the physician’s subsequent evaluation of the patient’s condition and therapy. It is recognised as the “gold standard”; however, both objective and subjective pathological diagnoses have limits, such as tissue corruption resulting from the nonstandard collection of diseased tissue, nonstandard tissue fixation or delivery, or a lack of necessary clinical data. In addition, diagnostic pathology encompasses too much information; thus, it requires time and effort to grow a trained pathologist. Consequently, computer-assisted diagnosis has become an essential tool for replacing or assisting pathologists with computer technology and graphical development. In this regard, the CAMELYON 17 competition was designed to identify the best algorithm for detecting cancer metastases in the lymph. Each participant was given 899 whole-slide photos for the development of their algorithms. More than 300 people enrolled on the competition. CAMELYON 17 is primarily focused on the categorization of lymph node metastases. The TNM classification system is the primary classification system. Participants at CAMELYON 17 mostly use categorization and learning techniques in deep learning and machine learning. In order to get a better understanding of the top-selected algorithms, we examine the advantages and limitations of traditional machine learning and deep learning for classifying breast cancer metastases.

Obstacles and Regulation Deconstruction of Athletes’ Psychological Training Based on Machine Learning Algorithm in Physical Education Teaching
Authors: Jiang Xin
Published: September 2022

In sports, players had differences in psychological training principles, sports characteristics, and personal athletic ability due to differences in sports plans. At the same time, the winning and losing rules of various competitions would also limit the psychological training and tactical ability of players. The current problem with mental training for athletes was that it is impossible to accurately understand the mentality of athletes and make a reasonable adjustment plan. Therefore, this paper adopted a machine learning algorithm and used the methods of psychological testing and questionnaire research to carry out extensive research on the training and regulation of remote sports psychology. The possible psychological barriers and adjustment methods of athletes are supplemented, focusing on the comparison of four aspects: psychological endurance before training, control accuracy, anxiety score before psychological training, and the effects of before and after adjustment. And after in-depth research on the problem of athletes’ psychological training, the conclusion showed that the psychological tolerance value of athletes has increased by 18.9%, the accuracy of control of athletes’ psychological problems had increased by 13%, the psychological anxiety of students had also been alleviated and improved, and the overall score had increased by 12.5%. A more systematic mental training program for athletes was introduced in order to provide a basis for improving the effectiveness of mental training for athletes.

Published: September 2022

Our purpose was to report clinical features in bilateral white dot syndrome in a 47-year-old female patient who was tested positive for the SARS-CoV-2. A 47-year-old female visited our department with complaints of bilateral photophobia and blurred vision in both her eyes. She visited our department during the pandemic period after her PCR-proven SARS-CoV-2 positivity. Her symptoms were chills and fever with a temperature of 40.0°C, associated with fatigue, sweat, and complete loss of taste. Besides basic ophthalmological examinations, ocular diagnostic testing were made to differentiate between specific white dot syndromes with suggestive features of fluorescein angiography, optical coherence tomography, and fundus autofluorescence. Laboratory tests were ordered, including immunserological and haematological ones. Eye examination revealed mild bilateral vitritis and white dots in the fundus of both eyes, including the macula explaining the blurred vision. Herpes simplex virus reactivation was proved, after the SARS-CoV-2 infection. Local corticosteroids were given according to the European Reference Network’s recommendations for patients with uveitis during the COVID-19 pandemic. Our report demonstrates that white dot syndrome with blurred vision could be associated with SARS-CoV-2 infection, being potentially sight-threatening because of macular involvement. Ophthalmological examinations found posterior uveitis white dot syndrome, and this should call attention to the risk of acute 2019-CoV infection or occurred 2019-CoV infection. Immunodeficiency favours the occurrence of other viral infections, such as herpes virus infections. Everybody should be aware of the risk of 2019-CoV infection, especially professionals, social workers, and those who work or live with elder people and people with immunodeficiency.

Published: September 2022

Despite the clinical impact of dysphagia in myasthenia gravis (MG), a standard protocol for diagnosing dysphagia reliably has not yet been established. High-resolution manometry (HRM) provides precise information on pharyngeal pressure. We hypothesized that swallowing pressure assessment using HRM during the edrophonium chloride (EC) test could identify mild bulbar symptoms with no abnormalities on videoendoscopic (VE) and videofluorographic (VF) examination of swallowing, and we tested this hypothesis on a 72-year-old female patient diagnosed with ocular MG who developed slight pharyngeal discomfort over 3 months. The patient’s ocular symptoms were stable with pyridostigmine medication. VE and VF revealed no abnormalities. The swallowing pressure along the pharynx was measured using HRM during the EC test. HRM parameters, including velopharyngeal contractile integral and meso-hypopharyngeal contractile integral, were evaluated. These parameters were assessed for three swallows using 3 mL of water. After EC injection, the values of the velopharyngeal contractile integral (78.0 ± 5.4 vs. 134.7 ± 1.3 mm Hg cm·s) and the meso-hypopharyngeal contractile integral were both higher (130.6 ± 1.5 vs. 284.2 ± 11.9 mm Hg cm·s) than those observed before EC injection. Chest computed tomography revealed a thymoma that had not been observed in previous examinations. The patient was diagnosed with thymoma-associated MG. Intravenous immunoglobulin therapy improved the mild dysphagia. We concluded that swallowing pressure assessment during the EC test may be helpful in identifying mild bulbar symptoms in patients with MG.
Hemorrhagic Macular Cysts in Patients with Terson’s Syndrome Observed through an Ophthalmic Surgical Microscope

Published: September 2022

The characteristics of hemorrhagic macular cysts (HMCs) in patients with Terson’s syndrome, focusing on the vitreoretinal interface observed through an ophthalmic surgical microscope, are described. Between May 2015 and February 2022, 19 eyes (17 patients) with vitreous hemorrhage (VH) occurring after subarachnoid hemorrhage underwent pars plana vitrectomy. After removing dense VH, 2 of 19 eyes had HMCs. In both cases with HMCs, they formed a dome-like shape and were located beneath the internal limiting membrane (ILM), lying beyond the clean posterior precortical vitreous pocket (PPVP) without hemorrhage despite the severe VH. Based on the microsurgical findings, it appears that two types of HMCs consisting of subhyaloid and sub-ILM hemorrhages in Terson’s syndrome may be involved in the impairment of adhesion of the posterior border of the PPVP and the ILM surface of the macula due to micro bleeding, and that the PPVP may prevent the sub-ILM type of HMC from breaking into the subhyaloid space and transforming into the subhyaloid type. In conclusion, the PPVP may play an important role in the formation of HMCs in Terson’s syndrome.

Published: September 2022

The aim of this report was to present a case of bilateral choroidal detachment following treatment with topical therapy dorzolamide/timolol without history of previous surgery. An 86-year-old woman, with intraocular pressures of 40.00/36.00 mm Hg, was treated with preservative-free double therapy with dorzolamide/timolol. One week later, she presented with bilateral vision loss and irritative symptoms in the face, scalp, and ears, with well controlled pressures. The anterior exam showed LOCS III N4C3 cataracts, and the fundus and ultrasound exams revealed a bilateral infero-temporal choroidal detachment in the absence of neoplasia or other systemic cause. One week in absence of hypotensive treatment and receiving topical prednisolone, she showed reattachment of the choroidal detachment. Six months after cataract surgery, the patient remains stable, without choroidal effusion regression. Hipotensive treatment following chronic angle closure can lead to choroidal effusion similar to cases of acute angle closure treated with oral carbonic-anhydrase inhibitors. The combined strategy of removing hipotensive treatment and topical corticosteroids could be useful for the initial management of choroidal effusion. Also, performing cataract surgery after choroidal reattachment can help with stabilization.

Published: September 2022

Neuroretinitis is an inflammatory condition with rapid unilateral vision loss, optic disc edema, and macular star formation. While neuroretinitis is commonly due to infectious causes such as Bartonella henselae, neuroretinitis due to toxoplasmosis is uncommon. A 29-year-old male presents to our neuro-ophthalmology clinic on December 7, 2021, at the University of Arkansas for Medical Sciences with symptoms of left eye pain and blurred vision. Subsequent workup led to the diagnosis and treatment of toxoplasma neuroretinitis. The fundus exam eventually demonstrated a notable macular star. Treatment was well tolerated, and the patient regained total visual acuity in the affected eye. Toxoplasma neuroretinitis is known for a characteristic appearance of optic disc edema prior to appearance of stellate maculopathy with vitreous inflammation and peripheral chorioretinal scars. Although loss of vision due to toxoplasmosis is rare, it should be included as part of the differential diagnosis with pertinent history.

Introduction: Our study aimed at stressing the significance of the vestibular system for ice hockey players, meanwhile focusing on the relation between the vestibular system and ice hockey for which balance is a significant factor. Our main aim was to compare the balance parameters of hockey players and normal individuals. Methods: Our experimental group consisted of 37 professional elite ice hockey players, and our control group consisted of 37 young males who have not previously been involved in sports as professionals. Participants had been subject to sensor organization test, adaptation test, weight-bearing/squat, unilateral stance, rhythmic weight-shifting tests of computerized dynamic posturography device. Results: Overall results indicate no significant difference between the control group and ice hockey players in the sensor organization test, which is caused by control group’s comprising adolescents with amateur sport involvement. In adaptation test and unilateral stance test, a significant difference was found between experimental and control groups. Discussion/Conclusions: This study determined the dynamic and static balance characteristics of ice hockey players. For this reason, it is useful to test the balance abilities of ice hockey players in static and dynamic conditions to evaluate their performance level. After testing individuals with vestibular problems with dynamic balance tests, appropriate sports exercises can be given to improve dynamic and static balance.
Surgical Masks May Hide Neurological Diagnoses

Published: September 2022

COVID-19 has disrupted the routine flow of patients through emergency departments (EDs) across the globe, including the need to consider COVID-19 for nearly all presenting complaints. The constraints of mask wearing and isolation have created inherent barriers to timely stroke care. We present a case that highlights one of the many ways in which the pandemic has negatively impacted the care of the non-COVID patient. A patient presented to the ED with a chief complaint of diffuse weakness and a new-onset cough on awakening. His daughter noted that he was slurring his words. An emergency medicine resident evaluated him, ordered laboratory studies, and decided to monitor the patient. The same resident later noted the patient veering to the left when walking, prompting a more detailed neurological examination. On removing the patient’s facemask, a left lower facial weakness was evident. The resident called a Code Stroke roughly 50 min after the patient initially presented to the ED. The patient proved to have an acute infarct at the right thalamocapsular junction. Universal masking policies during the COVID-19 pandemic should not prevent the routine assessment of cranial nerve function for all patients presenting to an ED.
Reducing the cost of energy used for adaptation by using different exterior wall covering materials in Iraq
Authors: Idan Mahmoud Fadhel
Published: September 2022

This paper aimed to study how to reduce the amounts of heat transfer from or to the internal space of the building by covering its external walls with many locally available materials, thus reducing the rate of consumption of electrical energy used in adaptation, which leads to reducing energy consumption costs. The researcher built a model room with dimensions (1 x 1 x 2) m on the third floor of a building in Baghdad (L = 33.2 N), the dimensions of its walls (1 x 2 m) east for the installation of the sample, and the other surfaces are insulated with 200 mm polystyrene sheets. Use a 0.5 ton air conditioner to provide the room thermal comfort. The researcher found that the metal sheet with a thickness of 10 mm and covered with an insulating layer of thermoplastics is considered the best among the materials used in construction, as it saves 57% of the electrical energy consumed in air conditioning. While the use of marble, porcelain, Helen stone, and fiberglass slabs with a thickness of 10 mm, comes last because it saves less than 30% of electrical energy.

Published: September 2022

This study examined the factor structure of the Organizational Health Inventory (OHI) scale among Omani teachers. There were four factors assumed to represent the OHI (principal influence, academic emphasis, morale, and initiating integrity). Testing the scale reliability was another aim of this study. A random sample (n=458) of Omani teachers was considered. The short version of the scale has 30 items. Exploratory and confirmatory factor analysis was performed on the sample data. The model is good fitted to the data. Across gender, the invariance of the structure was tested, and the parameters of the model were invariant. Consequently, the two genders were compared via multivariate analysis of variance (MANOVA) with gender as an independent variable and subscales. The female teachers were found to more likely show principal influence, academic emphasis, and morale than the male teachers, who instead, were more efficacious than the female teachers in dealing with institutional integrity.

The decision on school reopening has evoked mixed reactions from parents as they become nervous regarding this action and are uncertain to send their children to school. Therefore, this study was conducted to assess the teachers’ perspectives on the readiness and challenges of school reopening in Malaysia. A study was conducted through online interview sessions amongst 20 teachers for primary and secondary schools at Seremban district, Negeri Sembilan, Malaysia from October 2020 until February 2021. Data were coded into themes and sub-themes based on the similarities of the data. The respondents in this study agreed that they are ready for school reopening and fully follow the guidelines prepared by the Ministry of Education Malaysia such as checking body temperature, physical distancing inside and outside the classroom, enforcement of wearing mask and sanitize the area regularly. Undeniably, the teachers faced some challenges regarding new norms during school sessions. Therefore, to ensure that the students receive proper education, at the same time the measures to contain the transmission of COVID-19 are followed properly, a few suggestions have been made. The cooperation from the teachers, parents and students are also needed to ensure and achieve the smoothness of school sessions.

Published: September 2022

This study was conducted to determine the relationship between academic stress and life satisfaction among university students in Sabah, Malaysia. A total of 400 students were selected as respondents and data were collected using questionnaires. Academic stress was measured using the Perception of Academic Stress Scale (PAS), which has four subscales: i) Performance stress; ii) Workload perception of workload and examinations; iii) Academic self-perception; and iv) Time constraints. Meanwhile, the Satisfaction with Life Scale was used to study student’s life satisfaction. The data obtained were analyzed using Pearson correlation and t-test. The results showed that performance stress is negatively associated with life satisfaction, while academic self-perception is positively associated with life satisfaction. The result also showed that perception of workload and examinations and time constraints not associated with life satisfaction. All in all, academic self-perception and performance stress have an association with life satisfaction.

Learners can experience science in the real world by interacting with materials, collaborating with peers, and engaging in a problem-solving process. Notwithstanding, secondary school learners’ problem-solving skills (PSS) can be developed by using an instructional strategy that actively involves them in the learning process instead of sorely focusing on content learned. This paper shows how the production of materials for teaching and learning can go hand-in-hand with the development of learners’ PSS through the implementation of a Hands-on Instructional Model (HIM) in chemistry lessons. This study was a Design-based Research using a convergent mixed-method approach. The data was collected using lesson observation protocol, focus group discussions guide, and problem-solving test. On the aspect of the development of PSS, learners were enhanced with the skills to solve an ordinary chemistry problem and the criteria of observation were on the ways learners identify a problem, the approach used to solve the problem, and whether they could reflect on the answer they obtained. The findings indicate a substantial impact of HIM on learners’ PSS. Therefore, it is suggested that HIM should be used frequently to enhance learners’ active engagement in chemistry lessons and for further development of their PSS.

Research activity is one of the requirements for medical students in order to finish their study. Therefore, it needs to examine the knowledge and perceptions of medical students about medical research. The research design was an experimental one-group pretest-posttest design, involving 86 medical students, with the statistical tests using the Wilcoxon Signed-Rank Test. After the module implementation, the students’ knowledge about research had improved in the concept of theoretical basis, the concept of research methodology, and the biostatistics methods. However, there was no improvement in bioethical knowledge. Close relations between the result of pre- and post-research modules implementation were shown in the knowledge about theoretical basis, about research methodology, and the perception of workloads in college have (p<α). There were significant changes in knowledge (Z=-2.867, p=0.004) and perceptions (Z=-1.964, p=0.050) of the medical students pre- and post-research module. Giving research modules early, along with social and academic support for medical students, would improve their knowledge and positive perceptions towards research.

The future of students learning, and excellence of schools absolutely depend on the competence, skills, and expertise of its teachers. This study aimed to report on the validity and reliability of the practices of the learning organization instrument. The dimension of the learning organization questionnaire (DLOQ) instrument was used for the validity and reliability practices of learning organization among teachers. A total of 50 teachers who were selected at random from four indigenous primary schools located in Negeri Sembilan, Malaysia were the respondents in this survey study. The results showed: i) The item-content validity index (I-CVI) value achieved was between 0.67 to 1.00; ii) The scale-content validity index (S-CVI) value between 0.95 to 1.00; and iii) The modified kappa statistic between 0.57 to 1.00, proved that the DLOQ instrument adapted in this study had a high content validity. Hence, Cronbach’s Alpha values, Cronbach’s alpha if item deleted, inter-item correlation and corrected item-total correlation also explained that this instrument had high reliability. Therefore, the DLOQ instrument was reliable to measure characteristics of learning organization practices in the context of indigenous primary schools, Malaysia. In line with this, the practices of learning organization among teachers in schools especially primary schools need to be fully applied and implemented to produce more broadly skilled teachers, competent, have a high quality of teaching, able to produce students with high marketability, maintaining the sustainability of schools and educational institutions.

This study investigated technological pedagogical and content knowledge (TPACK) practices during the current COVID-19 pandemic and examined factors influencing students’ perceptions of effective online learning. This study gathered the primary data from 90 university students from four study programs via the online questionnaire. Using an analysis of variance (ANOVA) statistical tool for data analysis, this study found that students’ perceptions of their teachers’ teaching performance in the fully online programs are not significantly different across four study programs. This finding implies that regardless of their study programs, the students had expected that teachers should pay attention to some vital aspects in online learning: using the same learning management system (LMS) for all study programs, and preparing designing practical online modules, taking care of the organization of teaching inputs that promote students’ critical thinking, delivering various teaching inputs and methods, intensifying teachers’ presence in monitoring students’ learning progress, motivating students to learn, and promoting teacher-student mutual respect through effective communication. This study also revealed that teachers play a pivotal role in achieving effective online learning during the pandemic.

Examining students’ contentment with simulation is crucial for giving local and foreign academic teaching personnel feedback. The purpose of this study was to compare students studying emergency medical services’ simulation satisfaction. There were 193 students involved in a comparison cross-sectional design during the second semester of the academic year 2018 utilizing a paper-based English version of the satisfaction with simulation experience scale. The findings revealed a slight to moderate positive correlation for factor two (clinical reasoning), 0.510 (P<0.001); and factor three (clinical learning), 0.628 (P<0.001) for students. A slight negative correlation was also found in factor one (debrief and feedback) 0.092 (P<0.001). The study showed that the reliability was 0.906 for factor one, 0.860 for factor two and 0.872 for factor three. Cronbach’s Alpha for all factors: 0.937. ANOVA showed that factor three is significant with students’ level (df 3, f, 4.186, sig. 0.007). Compared to other factors, students were less satisfied with clinical learning simulation, due to unfamiliarity of students with the simulation mannequin and environment. The frequent implementation of simulation practice in emergency medical services field is highly recommended to enhance mainly clinical learning, master new skills and satisfaction with the learning experience.
