Published: April 2023

The era of technological disruption not only has an effect on changes in the business cycle, but also has an impact on the world of education. The world of education today also demands the ability to equip students with 21st century skills. These skills are the skills of learners who are able to think critically and solve problems, creatively, and innovatively, communication and collaboration skills. In the industrial era 4.0, universities are required to be able to overcome the turmoil of changes that occur due to digital transformation. Lecturers in the industrial era are required to have qualifications and competencies that can compete and survive in the turmoil of the industrial era 4.0. The purpose of this study was to determine how students perceive the competence of lecturers in the era of industrial disruption 4.0. The research method used in this research is quantitative research method with survey type. The data collection instrument used a questionnaire made through Google Forms. The sample of this study were 53 students of the Kerinci State Islamic Institute who were grouped by gender, namely 37 people (69.8%) were female and 16 people (30.2%) were male. Based on the results of the study, students were of the opinion that lecturers should be expressive and fun in teaching mathematics, lecturers should use online media to increase learning resources, lecturers should care about students and be helpful, lecturers should use language that is easy to understand, lecturers should not be rigid, lecturers should be formal and informal, lecturers should have good IT skills, lecturers in class should intersperse time with humor, lecturers should provide illustrations of theory in real and relevant forms, and ask students to use ICT in the learning process. Some of the obstacles that lecturers may face in implementing lecturer competencies in the era of industrial disruption 4.0 are lack of access and mastery of technology, lack of support from the university, and lack of awareness of the importance of lecturer competencies that are relevant to technological developments. Lecturers may also find it difficult to adapt the material taught to the rapid development of technology. To overcome these obstacles, lecturers need to be given support and training to improve their mastery of technology, as well as encouragement to continue developing their competencies.

Comparative Study of Water Desalination using Reverse Osmosis (RO) and Electro-dialysis Systems (ED): Review
Authors: Kadhim Roaa Ahmed , Khudhair Basim Hussein , Jaafar Mahdi Shanshal
Published: April 2023

The increasing drinking water demand in many countries leads to an increase in the use of desalination plants, which are considered a great solution for water treatment processes. Reverse osmosis (RO) and electro-dialysis (ED) systems are the most popular membrane processes used to desalinate water at high salinity. Both systems work by separating the ionic contaminates and disposing of them as a brine solution, but ED uses electrical current as a driving force while RO uses osmotic pressure. A direct comparison of reverse osmosis and electro-dialysis systems is needed to highlight process development similarities and variances. This work aims to provide an overview of previous studies on reverse osmosis and electro-dialysis systems related to membrane module and design processes; energy consumption; cost analysis; operational problems; efficiency of saline removal; and environmental impacts of brine disposal. RO system uses osmotic pressure as a driving force to force water through the membrane with less energy than other desalination systems. The enhancements in membrane materials and power recovery of the unit have massively decreased the price of RO units. ED system uses an electrical current to push dissolved ions across ion exchange membranes. The results of this review showed that desalination plants must be integrated with renewable energy to reduce power consumption and costs related to energy. Various technologies, including treatment processes and disposal methods, must be used to control concentrated solutions resulting from desalination processes because 5 to 33% of the total cost of the desalination process is associated with brine disposal.

It is widely acknowledged that CO2, a greenhouse gas, is largely responsible for climatic changes that can lead to warming or cooling in various places. This disturbs natural processes, creating instability and fragility of natural and social ecosystems. To combat climate change, without compromising technology advancements and maintaining production costs at acceptable levels, carbon capture and storage (CCS) technologies can be deployed to advance a non-disruptive energy transition. Capturing CO2 from industrial processes such as thermoelectric power stations, refineries, and cement factories and storing it in geological mediums is becoming a mature technology. Part of the Mesohellenic Basin, situated in Greek territory, is proposed as a potential area for CO2 storage in saline aquifers. This follows work previously done in the StrategyCCUS project, funded by the EU. The current investigation includes geomechanical and petrophysical methods to characterise sedimentary formations for their potential to hold CO2 underground. The work is progressing under the Pilot Strategy, funded by the EU.

Basin and depositional control on the initiation and development of fluid-escape pipes in the Canterbury Basin, New Zealand.
Authors: Omosanya Kamaldeen , Micallef Aaron , Harishidayat Dicky
Published: April 2023

The influence of basin and depositional context on the formation and growth of fluid escape pipes in sedimentary basins is not fully understood. While seismic reflection data is commonly used to study these structures, direct observation and sampling of field analogues of pipes and their related structures are rare. In this study, we investigate the evolution of meter-tall fluid escape pipes (100-800 m) in the Canterbury Basin, New Zealand, using open source seismic and borehole data. Our analysis includes seismic interpretation of 19 unconformities within the Neogene-Quaternary successions, characterization of pipes and fluid-related anomalies in the subsurface, modelling of the shale volume (Vsh), lithology characterization, 3D static modelling, and seismic inversion. We identify thirty-one vertical to sub-vertical pipes with three parts consisting of top, main conduit/stem, and root zone on seismic profiles. Our results suggest that lithology plays a crucial role in the initiation and modulation of pipe structures in the Canterbury Basin, with pipes mostly formed post Tarantian (0.113 Ma) and truncated at the U19 unconformity. Furthermore, vertical fluid migration from overpressured units, such as the tops of contourite mounds, was observed in the pipes. Our findings provide new insights into the subsurface fluid flow and sedimentary architecture of the Canterbury Basin and have wider implications for other passive continental margins with similar characteristics.
Preclinical study the potential of sonosensitizer-mediated sonodynamic therapy on malignant brain tumor treatment
Authors: Huang Chiung-Yin , Wei Kuo-Chen
Published: April 2023

Malignant glioma is a common and severe primary brain tumor, the prognosis is extremely poor with a median overall survival of approximately 1 year, and a relative very low survival rate at 5 and 10 years approximately (5% and 3%, respectively). Therefore, development for new treatment strategy is in urgent need. Recently, the potential of sonodynamic therapy (SDT) using sono-sensitive molecules such as 5-aminolevulinic acid and fluorescein to treat brain tumor is highly noted. In the present study, rodent subcutaneous and brain tumor models were used to evaluate the treatment effect for SDT. These data will serve as references for clinical trial application to Taiwan FDA.MethodsRat C6 glioma cells were subcutaneously implanted to the hind flank of SD rats. For brain tumor model, glioma cells were inoculated into the striatum under the assistance of stereotaxic frame. Treatment effect of 5-ALA / fluorescein assisted SDT were evaluated by the tumor size changes. The histological features of tumor specimen were investigated by apoptosis-specific staining to determine the pathological changes post SDT treatment.ResultsBoth 5-ALA and fluorescein were used to test the SDT treatment effect. For fluorescein assisted SDT, 16mg/kg fluorescein were intraperitoneally administered and treated with FUS (0.35MPa, duty10% for 10min). For 5-ALA assisted SDT, 180mg/kg 5-ALA were orally administered and treated with FUS (0.4MPa, duty10% for 20min). The tumor growth rate of both SDT groups were significantly inhibited as compared with control groups. ConclusionsIn this study, we examined the effect of 5-ALA and fluorescein assisted SDT on subcutaneous C6/SD tumor model. The orthotopic brain tumor model was also used to evaluate the effect of 5-ALA-SDT. Our study demonstrated that tumor growth rate was significantly inhibited by combination of both sonosensitizers, suggesting they are both safe and effective for noninvasive SDT tumor treatment.
Evaluating Dynamics in Affect Structure with Latent Markov Factor Analysis
Authors: Vogelsmeier Leonie V. D. E. , Cloos Leonie , Kuppens Peter , Ceulemans Eva
Published: April 2023

In intensive longitudinal research, researchers typically consider the structure of affect to be stable across individuals and contexts. Based on an assumed theoretical structure (e.g., one bipolar or two separate positive and negative affect constructs), researchers create affect scores from items (e.g., sum or factor scores) and use them to examine the dynamics therein. However, researchers usually ignore that the affect structure itself is dynamic and varies across individuals and contexts. Understanding these dynamics provides valuable insights into individuals’ affective experiences. This study uses latent Markov factor analysis (LMFA) to study what affect structures underlie individuals’ responses, how individuals transition between structures, and whether their individual transition patterns differ. Moreover, we explore whether the intensity of negative events and the personality trait neuroticism relate to momentary transitions and individual differences in transition patterns, respectively. Applying LMFA to experience sampling data (N = 153; age: mean = 22; standard deviation = 7.1; range = 17 – 66), we identified two affect structures—one with three and one with four dimensions. The main difference was the presence of negative emotionality, and the affect dimensions became more inversely related when the affect structure included negative emotionality. Moreover, we identified three latent subgroups that differed in their transition patterns. Higher negative event intensity increased the probability of adopting an affect structure with negative emotionality. However, neuroticism was unrelated to subgroup membership. Summarized, we propose a way to incorporate contextual and individual differences in affect structure, contributing to advancing the theoretical basis of affect dynamics research.

Authors: Avinash H Rajanna  , Ijantkar Sandeep , Vaibhav S Bellary
Published: April 2023

Background: Variceal bleed is one of the major complications seen in patients with cirrhosis of liver of various etiologies and endoscopy is a gold standard for its diagnosis which is an invasive procedure. There are other modalities of non-invasive methods to determine the degree of varices and estimation of serum albumin levels in one among them.
Aims and Objectives: The aims of this study were as follows: (1) To measure serum albumin levels in patients with cirrhosis of liver and (2) to correlate serum albumin levels with grading of esophageal varices.
Materials and Methods: A cross-sectional study was conducted on a total of 100 patients in Bangalore during the study period from October 2016 to September 2017. Case record form with follow-up chart was used to record the duration of disease, history of treatment and complications. Patients underwent biochemical investigations and endoscopy. The presence of varices and their size was obtained from endoscopy reports.
Results: Study includes 100 patients that majority belonged to the age group 40–49 years (46%). Serum albumin levels of <2.8 mg/dL was seen in high number of study subjects (76%). Forty patients had albumin levels of <2.8 mg/dL with grade 3 OGD scopy, followed by 23 patients with Grade 1 esophagogastroduodenoscopy (OGD scopy). The association between albumin and OGD scopy grades was found to be significant (P=0.027).
Conclusion: We conclude that low albumin levels predict higher grades of esophageal varices. It can identify the subset of patients who require prophylactic endoscopic management. Estimating serum albumin levels are non-invasive that can screen the patient for esophageal varices. Thus, this reduces the economic burden on the patients and the cost of management of esophageal varices.

Authors: Sonia Jaiswal  , Pradeep Kumar Sharma  , Tahsin Munsif
Published: April 2023

Background: Tobacco-induced mucosal changes have been identified in exfoliated cells. The morphology of the exfoliated cells depends on the nature of the changes taking place in the epithelial layer; conversely, alteration in cytological pattern may be attributed to the changes occurring in the epithelial layer. Applying this possibility, exfoliative cytological techniques have been applied to examine the effect of tobacco on the oral mucosa.
Aims and Objectives: The study was conducted to study the alterations in the cellular diameter of buccal mucosal cells.
Materials and Methods: In a case controlled study, 240 participants were divided into four groups according to their habit of consumption of tobacco leaves, tobacco with areca nut, participants with oral lesions, and participants without any such habit. The groups were, further, subdivided according to their age. Desquamated cells from the buccal mucosa of were collected and smeared on a slide. The cells were stained with Papanicolou (rapid kit). Fifty cells per slide were studied and photomicrographs were obtained at ×40 magnification. The cellular diameter was obtained using the Leica 1000 software.
Results: The mean cell diameter was found to be highest in the group of normal subjects (49.51±7.31 micron), followed by the group of tobacco users (43.52±1.92 micron) and Gutkha users (39.05±3.57 micron). The mean cell diameter was minimum (24.97±3.13 micron) in the group of oral lesion patients. According to the ANOVA test, the difference in cell diameter among various groups is found to be highly significant (P<0.0001).
Conclusion: Tobacco used in any form can induce changes in the buccal mucosa. In our study, mean cellular diameter decreased from normal-cells to cells affected by oral lesions.

Background: Coronavirus disease 2019 (COVID-19) was a recent global pandemic of the era which posed a great challenge for the health care in terms of preventive, diagnostic and treatment dimensions. The seroprevalence rate of COVID IgG antibodies is very crucial in estimating the susceptibility of a particular area to the viral disease. In our study, we estimated the seroprevalence of COVID-19 in a rural area.
Aims and Objectives: We aimed to estimate the seroprevalence of COVID-19 in a rural district of Tamil Nadu, 6 months after the index case.
Materials and Methods: We conducted a cross-sectional study of 509 adults aged more than 18 years. From all the seven Taluks, two gram panchayats (administrative cluster of 8–10 villages) were randomly selected followed by one village through convenience. The participants were invited for the study to the community-based study kiosk set up in all the eight villages through village health committees. We collected sociodemographic characteristics and symptoms using a mobile application-based questionnaire, and we tested samples for the presence of IgG antibodies for severe acute respiratory syndrome coronavirus 2 using an electro chemiluminescent immunoassay. We calculated age-gender adjusted and test performance adjusted seroprevalence.
Results: The age-and gender-adjusted seroprevalence was 8.5% (95% confidence interval [CI] 6.9–10.8%). The unadjusted seroprevalence among participants with hypertension and diabetes was 16.3% (95% CI: 9.2–25.8) and 10.7% (95% CI: 5.5–18.3), respectively. When we adjusted for the test performance, the seroprevalence was 6.1% (95% CI 4.02–8.17). The study estimated 7 (95% CI 1:4.5–1:9) undetected infected individuals for every reverse transcription polymerase chain reaction confirmed case. Infection fatality rate (IFR) was calculated as 12.38/10,000 infections as on October 22, 2020. History of self-reported symptoms and education were significantly associated with positive status (P<0.05).
Conclusion: A significant proportion of the rural population in a district of Tamil Nadu remains susceptible to COVID-19. A higher proportion of susceptible, relatively higher IFR, and a poor tertiary health-care network stress the importance of sustaining the public health measures and promoting early access to the vaccine are crucial to preserving the health of this population. Low population density, good housing, adequate ventilation, limited urbanization combined with public, private, and local health leadership are critical components of curbing future respiratory pandemics.

Background: Chronic kidney disease (CKD) is a major public health problem in developing countries, adversely affecting the quality of life (QOL) of the individual and their family. Perceived social support and hope are important factors influencing the QOL.
Aims and Objectives: The objectives of the study were to assess the QOL among patients with CKD and the effects of perceived social support and hope on QOL.
Materials and Methods: This is hospital based cross-sectional study among CKD patients attending nephrology department, between March and November 2018. Face to face interview using Adult Hope Scale and Multidimensional Perceived Social Support scale and WHOQOL-BREF-26 was done after obtaining informed consent. Epi-info and SPSS16.0 were used for statistical analysis. t-test, ANOVA, and correlation coefficient was done to find any association.
Results: Among the 152 participants, majority (70%) had fair QOL with the highest score in social relationships domain of 53 (±12), using the WHO BREF26 questionnaire. The QOL was also found to be associated with education and socio-economic status. A positive correlation between perceived social support and hope with QOL was observed.
Conclusion: Majority had a fair QOL, with the highest score in social relationship domain. Positive correlation was observed between perceived social support and hope with QOL. Apart from medical treatment, the key to better health outcome depends on social support. Hence, it is imperative to highlight the importance of social support and hope at the commencement of the treatment of CKD.

Published: April 2023

Background: Laparoscopic cholecystectomy has become the mainstay of treatment for gallstone disease cases due to its lower morbidity and pain compared to open techniques. Unfortunately, the use of carbon dioxide to insufflate the abdomen is the main contributor to post-operative shoulder pain.
Aims and Objectives: The aim of the study was to evaluate the effectiveness of retaining the epigastric port trocar in position until rest all ports closed after completion of lap cholecystectomy in decreasing the post-operative shoulder pain.
Materials and Methods: A prospective, randomized, and clinical trial was done in AIIMS hospital, Bhubaneswar, on 102 patients who have undergone laparoscopic cholecystectomy. The patients were alternatively selected, one in the study group (52) and the other in the control group (50). For those patients in the study group, after the completion of the surgery, the epigastric port trocar is retained in position until the rest of all ports were closed. In the control group, all trocars were removed and port closure was done. The patients were evaluated for the next 24 h for post-operative shoulder pain. A numerical rating scale (NRS) was used to assess shoulder pain on patient arrival to the ward, at 4, 6, 12, and 24 h postoperatively. One hundred and two patients were included in the final data analysis.
Results: NRS pain scores were significantly lower in the study group at 6, 12, and 24 h post-laparoscopic cholecystectomy compared to the control group with no additional requirement of IV analgesics.
Conclusion: Retaining the epigastric trocar in position is an easy way that is beneficial in reducing post-operative shoulder pain post laparoscopic cholecystectomy surgery.
