Determining dimensions of job satisfaction in healthcare using factor analysis
Authors: Karaferis Dimitris , Aletras Vassilis , Niakas Dimitris 
Published: October 2022

Abstract
Background:
Job satisfaction in health care has a great impact as it affects quality, productivity, effectiveness, and healthcare costs. In fact, it is an indicator of the well-being and quality of life of the organization’s employees, as it has been variously linked with increased performance and negatively to absenteeism and turnover. Better knowledge of healthcare employees’ job satisfaction and performance can directly contribute to the quality of the services provided to patients and is critical for the success of organizations.

Methods:
The Cronbach’s alpha coefficient, split-half reliability, exploratory factor and confirmatory factor analysis were employed to assess the reliability and validity of JSS.

Results:
Six underlying dimensions were extracted (benefits and salary, management’s attitude, supervision, communication, nature of work, and colleagues’ support). Internal consistency reliability was satisfactory since Cronbach’s alpha for the overall scale was 0.81 and for the various dimensions ranged from 0.61 to 0.81, respectively. Exploratory factor analysis showed a KMO value of 0.912. The confirmatory factor analysis indicated good fit: SRMR = 0.050, RMSEA = 0.055, IFI = 0.906 and CFI = 0.906.

Conclusion:
Job satisfaction is a multidimensional construct that encompasses different facets of satisfaction. There is a lack of consensus as to which factors are more important and a researcher may find satisfaction with some factors while at the same time dissatisfaction with others. Our findings are significant for improving our understanding of the nature and assessment of job satisfaction in the Greek healthcare context, providing a more stable ground in a rapidly changing environment. A short JSS developed that could be much more widely used in the future.

Published: October 2022

Abstract
Background
Alexithymic and psychopathic traits are closely associated, but distinct constructs. Both have been associated with facial emotion processing deficits reflecting empathy deficits, however the underlying mechanism contributing to these deficits is not well-understood.

Methods
This study investigated facial emotion recognition performance in a non-clinical sample (N = 110) including both male and female participants, with varying levels of psychopathic and alexithymic traits. Facial emotion recognition was assessed using a computerized task, that presented different expressions depicting five emotional states (pain, fear, sadness, anger, happiness) and neutral expressions.

Results
Results suggest that the high psychopathic traits group reported lower accuracy compared to the low psychopathic traits group, indicating a more generalized deficit in facial affect recognition, across all emotions. The alexithymic groups (high vs. low) on the other hand did not differ in their performance on the task for any of the emotions presented.

Conclusion
These findings add to the current body of research regarding face processing categorization deficits in relation to psychopathic and alexithymic traits and can inform prevention and intervention efforts that aim to facilitate facial emotion recognition in individuals with these personality traits.
Test review: French examination of the College Scholastic Ability Test in Korea
Authors: Choi Yoonhee , Chun Jihye 
Published: October 2022

AbstractThis study reviews the French examination of the College Scholastic Ability Test (CSAT), the most influential and highest-stakes test in Korea. The CSAT score has considerable influence on university admissions, and admission to a highly ranked university is generally a prerequisite for socioeconomic success. From this perspective, the significance of the CSAT is enormous. In general, the assessment is influenced by the goals and content of the curriculum, and it also plays an important role in curriculum implementation. In Korea, the national curriculum has been recently reformed. The main goal of the reformed French curriculum is to promote communicative skills and cultural literacy. However, the examination has been criticized for not uniformly or adequately evaluating overall communicative skills. Considering the importance of the CSAT and the interdependence of assessment and curriculum, the CSAT French examination has to be reviewed from the perspective of test quality. Due to its limited assessment of communicative skills, the validity of the French examination is debatable. The problem of low reliability also arises due to the uncertainty of assessment criteria and guidelines. Authenticity and interactiveness could be improved by avoiding fragmentary knowledge and memorization-oriented assessment. The negative washback effect needs to be addressed to resolve the low relevance of the curriculum to the test and the relatively low applicability of the CSAT French score in university admission policy.
The light aging behavior of daylight fluorescent paints: a colorimetric, photographic, Raman spectroscopic and fluorescence spectroscopic study
Authors: Reiß Lukas , Prestel Thomas , Giering Sarah 
Published: October 2022

Abstract
Daylight fluorescent pigments with their intense color effects have attracted great interest among artists since their market launch in the mid-twentieth century. Since then they have been widely used in the visual arts. The pigments are mainly compositions of organic fluorescent dyes and optical brighteners diluted in an insoluble resin. Due to the susceptibility of the dyes to visible and UV radiation, their lightfastness is comparatively low. This paper presents a comprehensive study of the color and fluorescence changes of daylight fluorescent paints upon exposure in visible light and ultraviolet radiation conducted on mock-ups of commercial daylight fluorescent pigments. The different aging characteristics of the pigments depend on the color tone. They were recorded by means of photographic and colorimetric documentation. In addition, Raman spectroscopy was used to identify the main dyes of the various pigments, even in the complex system of paints, consisting of primer, binder, resin and dyes, and to determine their degradation during aging. Fluorescence spectroscopy revealed that the change in fluorescent color may not only be due to the decrease in dye concentration, but also to the transformation of the original dyes into other fluorescent compounds during light aging. Finally, this paper provides recommendations for the presentation of artworks containing daylight fluorescent pigments.
Dehydrocostus lactone ameliorates lipid accumulation, insulin resistance, and endoplasmic reticulum stress in palmitate-treated hepatocytes
Authors: Hong Yeonhee , Lee Minji , Kim Chanseul , Kim Gun-Hwa 
Published: October 2022

AbstractFatty liver disease is caused by lipid accumulation in the liver, insulin resistance (IR), reactive oxygen species (ROS), and endoplasmic reticulum (ER) stress. Dehydrocostus lactone (DHE) has anticancer, anti-inflammatory, and anti-ulcer effects. However, its effects on hepatic steatosis and IR remain unclear. In this study, we investigated whether DHE has antisteatotic effect on fatty liver in vitro. Hepatocytes HepG2 and SNU-449 cells were exposed to 0.25 mM palmitate (PA), and then antisteatotic effect was evaluated by treatment with 10 μM DHE. DHE treatment reduced lipid accumulation and lipogenesis factor protein levels, compared with PA-treated hepatocytes. DHE treatment also decreased gluconeogenesis marker expression and recovered IR in PA-treated hepatocytes, and promoted glucose uptake in PA-treated HepG2 cells. Additionally, the levels of ROS and ER stress factors in PA-treated HepG2 cells were reduced by DHE treatment, compared with PA-treated HepG2 cells. Overall, DHE decreased lipid accumulation and lipogenesis factors as well as recovered IR, gluconeogenesis, and glucose uptake by reducing ER stress and ROS levels in PA-treated hepatocytes. Thus, DHE is a potential antisteatotic agent.

Abstract
Background
Despite appropriate treatment of epilepsy, the treatment outcome is poor in developing country. Therefore, the study was aimed to identify the magnitude and associated factors of epileptic patients at ambulatory clinic of south western Ethiopian hospital.

Methods
A hospital-based cross-sectional study was conducted on epileptic patients who had follow-up at Mettu Karl Comprehensive Specialized Hospital (MKCSH). Data collection was done through patient interview and medical charts review. The pharmaceutical care network Europe foundation classification system was used to assess the drug therapy problem and Naranjo algorithm of adverse drug reaction was employed to identify the probability of adverse drug reaction. The data were analyzed by SPSS version 23 after data were entered by Epidemiological Information (Epi Info) 7.2.1. The multivariable logistic regressions were utilized and P < 0.05 was used to declare association.

Results
Over the study period, more than half of the participants 172(57.7%) were males. The magnitude of drug-related problems was found to be 164(55.0%). Among epileptic patients about 323 drug-related problems (DRPs) were identified on average, 1.084 drug-related problems (DRPs) per patient. The widely occurred types of drug-related problems were needs additional drug therapy 72(22.29%), dose too low 52(16.09%) and dose to high which accounts 50(15.48%). Regarding the predictors of drug-related problems, being a female (AOR = 3.57, 95% CI:1.85–6.88, P ≤ 0.001), having frequent seizures (AOR = 2.47, 95% CI%:1.33–4.61, P = 0.004) and the presence of poly-pharmacy (AOR = 3.57, 95% CI: 1.49–8.5, P = 0.004) were predictors of drug-related problems.

Conclusion
More than half of the patients had a drug therapy problem. Number of medications taken by the patients, gender and the seizure frequency had a significant association with occurrence of drug therapy problems (DTPs). Therefore, the pharmaceutical care in general and drug information services in particular should be established to hinder any undesirable medication effects in our study area.
Development of a high-speed and low-torque loss two-way clutch
Authors: Waragai Masaki , Takayama Toshio 
Published: October 2022

AbstractIn this study, a two-way clutch mechanism using planetary gear meshing was proposed. The proposed mechanism allows low torque loss and high-speed rotation instead of a larger backlash compared to a roller type two-way clutch. The unique structure of this mechanism that makes such functionality possible comprises two independent planetary gears with variable distances between the axes. When the input shaft rotated, the planetary gears rotated at a distance. Torque is transmitted by the input shaft pushing directly on the output shaft, so losses on the tooth surface are small. As with gear reducers, high-speed rotation is possible. When the output shaft rotated, the two planetary gears engaged, and the shaft locked. A flat cam was used to switch between the above two states, so the overall structure was simple. The diameter, thickness, and weight of the developed prototype were 44 mm, 24 mm, and 78.8 g, respectively. We experimentally confirmed that the mechanism worked as expected. The theoretical locking limit torque was 1.16 Nm. The torque loss was 5 mNm at the static condition and less than 10 mNm at a high speed of 4000 rpm.

Published: October 2022

Abstract
Background
Open pneumothorax with chest wall deficit is a rare chest trauma that is serious and can lead to severe respiratory failure; however, it is a potentially lifesaving injury if utilized appropriately.

Case presentation
Herein, we report a case of an open pneumothorax with extensive chest wall deficit due to falling from a height and highlight the importance of appropriate evaluation and intervention. The patient was a Japanese man in his 50 s who fell from the 6th floor to the 3rd floor while working at a height. The left chest wall was punctured due to injury, the thoracic cavity was open as if a left anterolateral thoracotomy had been performed, and the left lung had prolapsed from the thoracic cavity to the outside. In our emergency department, tracheal intubation with a double lumen tube for differential positive pressure ventilation and a right thoracic drain were inserted, and an emergency operation was started immediately. A pulmonary suture for lung injury and closure of the left thorax were performed during the surgery. The defect was closed with the remaining tissue, but the anterior thoracic skin with poor blood flow was necrotic, so debridement was undertaken. After his general condition was improved, pedicled latissimus dorsi myocutaneous flap was implanted. He was discharged home on the 63rd hospital day.

Conclusions
Although open pneumothorax is rare and sometimes presents lurid findings, we highlighted that it is important to quickly assess the life-threatening organ injury, perform positive pressure ventilation by tracheal intubation, thoracic drainage, and wound closure simultaneously respond calmly as a team.

Abstract
Background
The pandemic of the newly emerged coronavirus infection and its related disease, Covid-19, has influenced various aspects of human life including dietary habits. This study aimed to examine changes in dairy products consumption during Covid-19 lockdown period in a huge sample of Iranian households.

Methods
A cross-sectional descriptive-analytical study using a web-based electronic self-administered questionnaire designed to detect any changes in the consumption frequency of dairy products in the Iranian households during Covid-19 lockdown.

Results
A total of 21,290 households were enrolled. During Covid-19 epidemic lockdown, about 29%, 26% and 7% of the households had decreased their consumption frequency of milk, yogurt and cheese, respectively. The female-headed households were 21% more likely to decrease their consumption of milk, compared with male-headed households (OR = 1.21, 95% CI: 1.05–1.4). The households residing in food insecure provinces were 29%, 20% and 45% more likely to decrease their consumption of milk, yogurt and cheese as compared with those living in the food secure provinces. About 37%, 25.3%, 19.4% of those households who reported a decrease in consumption of dairy products had fully omitted them.

Conclusion
We found considerable decrement of dairy products consumption, especially milk and yogurt, in a high proportion of the studied households. Inadequate intake and, in some households, omission of dairy products can potentially bring about serious health outcomes with heavier economic burden. Further studies to track these changes over time and to evaluate their health consequences are warranted.
Maritime fuels of the future: what is the impact of alternative fuels on the optimal economic speed of large container vessels
Authors: Kouzelis Konstantinos , Frouws Koos , van Hassel Edwin 
Published: October 2022

AbstractThis study aims to determine the most appropriate alternative fuel technology to comply with possible different imposed emission regulations while ensuring optimal business performance. In this context, the most suitable alternative fuel technology minimizes the required freight rate while maximizing overall performance on technological, environmental, and other criteria. A decision support tool was developed combining the overall performance of alternative fuels based on technological, environmental, and other criteria via a simple multiattribute rating technique model with a financial model based on discounted cash flow analysis. In this model, also an optimization model is implemented to minimize the required freight rate by optimizing for economic vessel speed. This model provides quantified insights into the financial and operational effects of transitioning via either a 'market-based measure' regulatory scenario or an 'emission cap' scenario if current fuels do not reach the zero-emission targets in the future. Based on the analysis, it can be concluded that upgraded bio-oil, Fischer–Tropsch diesel and liquefied bio-methane can be considered the 'most promising' alternative maritime fuels of the future. Current fuels such as Heavy fuel oil and Liquified natural gas remain the 'most probable' to retain dominance without regulations. If there is a transition toward these alternative fuels, this will also lead to a shift toward lower sailing speeds.
Adapting a simple surgical manual tool to a 3D printed implantology protocol: the use of a universal screwdriver for fixation of custom-made laser sintered titanium subperiosteal implants
Authors: Ayna Mustafa , Gülses Aydin 
Published: October 2022

Abstract
Purpose
Current paper aims to describe a simple technique used for the fixation of the screws of a customized implant via a universal screw driver (BoneTrust® Easy Screw according to Dr. Bayer, Medical Instinct®, GmbH, Germany) to simplify the surgical placement of the customized implants.

Methods
The insertion of the drilling screws for the retention of the implant with angulated handpiece into the palatinal region or zygomatic buttress were performed with universal screw driver.

Results
The retention screws could be inserted with a proper angulation without interfering with the surrounding tissues. The technique described herein has significantly simplified the surgical intervention.

Conclusion
The insertion of the drilling screws for the retention of the implant with angulated handpiece into the palatinal region or zygomatic buttress could be challenging, thus the anatomical structures and the insufficient length of the handpiece could interfere with the placement of the screw with a proper angulation. This problem could be easily managed with the use of universal screw driver.

Published: October 2022

AbstractBackgroundPyrazinamide (PZA) is efficient antituberculosis drug. However, PZA-induced hepatotoxicity mediated by oxidative damage is documented. Naringenin (NGN) is a common flavanone with antioxidative properties. Thus, the present work aimed to elucidate the protective role of NGN against PZA-induced toxicity in rats. Eighty adult male Wister rats were randomly divided into four groups: control, PZA, NGN and NGN+PZA. Rats were orally administered 155 mgPZA/kg or 50 mgNGN/kg or NGN 1 h before PZA daily. After 1, 2, 3 and 4 weeks, blood and liver were collected for hematological, biochemical, and histopathological investigations.ResultsAdministering PZA alone caused remarkable declines in the white and red blood cell counts, hemoglobin content, packed cell volume, and serum levels of albumin, albumin/globulin ratio, high-density lipoprotein cholesterol, and hepatic activities of superoxide dismutase, and glutathione reductase and glutathione level. Serum levels of total cholesterol, low-density lipoprotein cholesterols, triglycerides, globulin, glucose, total and indirect bilirubin, malondialdehyde, and aminotransferases activities were markedly elevated. Additionally, the liver of PZA group exhibited considerable histopathological alterations. Inversely, in the NGN+PZA group, all the aforesaid disturbances in the studied parameters were ameliorated.ConclusionsThe current study revealed that NGN can be successfully utilized during treatment with PZA to prevent its side actions.

Abstract
Background
Depression is associated with morbidity, death, diminished quality of life, decreased longevity, and even suicidal ideation in hemodialysis patients. Intra-dialytic exercise is considered as integral component of the clinical care management of hemodialysis patients as it improves hemodialysis effectiveness, reducing systemic inflammation, increasing exercise tolerance, decreasing depression and improving quality of life. The objective of this study was to assess the effect of intra-dialytic physical exercise on depression and physical activity in prevalent hemodialysis patients. This prospective cohort research comprised 50 hemodialysis patients maintained on regular hemodialysis 3 times/week with duration since starting dialysis (1–5 years), not practicing any previous physical activity, suffering from depressive symptoms, not maintained on antidepressants and separated into two groups: group I underwent intra-dialytic exercise for 3 months and group II was matched in age and gender but did not undertake any exercise.

Results
Hamilton depression rating scale was significantly decreased in group I after completing the exercise program compared to baseline (P = 0.000), while there was no significant change in group II. Serum tumor necrosis factor alpha significantly decreased in group I compared to baseline (P = 0.000), while there was no significant change in group II. A positive correlation was found between serum tumor necrosis factor alpha and Hamilton depression rating scale (r = 0.676), (P = 0.000). Physical activity tests; 6-min walk test, rapid assessment of physical activity and peak volume of oxygen consumption were significantly improved in group I compared to baseline (P = 0.000), while there was no statistically significant difference in group II. Serum phosphorus and parathyroid hormone levels were significantly decreased in group I compared to baseline (P < 0.01), while urea reduction ratio was significantly increased in group I compared to baseline (P = 0.000), but there was no significant change in group II.

Conclusions
Intra-dialysis exercise can improve depression and physical performance in hemodialysis patients. As positive correlation was found between serum tumor necrosis factor alpha and Hamilton depression rating scale, so tumor necrosis factor alpha may be considered as marker of depression in hemodialysis patients. Intra-dialytic exercise can improve dialysis efficacy by improving urea reduction ratio.
