Authors: Fu Wen Heng , Satrianawati Satrianawati
Published: October 2023

This research aims to explore the competence of digital pedagogy of teachers towards the establishment of students’ digital ethics in the modernization of Indonesian education. This research uses the phenomenological approach to examine the essence of teachers' digital pedagogy competence. We collected the data using semi-structured interviews with five primary school teachers in Indonesia who have worked for more than three years. We chose the subjects based on their capability in guiding students in their routine. The results showed that the pedagogical teaching competence to establish the students’ digital ethics in education modernization are driven by some factors, namely: (1) the teachers have responsibility at work to self-actualize, (2) the teachers have high confidence to establish digital ethic in education modernization, and (3) the teachers use research and spiritual approaches to change the students’ ethics in education modernization. These three factors ultimately encourage teachers to establish digital ethics in education modernization. Therefore, it is important to establish the policy regarding the pedagogy digital competence. Furthermore, teachers can also take advantage of these findings by maximizing antecedent factors to increase digital pedagogy competence at work.

Published: October 2023

There has been a renewed and strong interest in phase change materials (PCMs) in many fields beyond traditional memories, due to their optical and electrical tunability aspect. Given their unique characteristic of changing phase and refractive index on-demand from amorphous to crystalline and vice versa via optical or electrical switching, they can be employed in many applications ranging from optical filters to rewritable metasurfaces. Patterning PCMs into self-assembled nanorod structures much smaller than the wavelength in diameter could potentially lead to interesting applications such as controlled chirality, birefringence and anisotropy. Additionally, such nanorod geometries may potentially lead to robust switching over multiple cycles for films of thicknesses well beyond those that are switchable in bulk thin film geometries. In this work, we grow and characterize self-assembled nanorods of antimony selenide PCM, and we characterize the nanostrucutres using ellipsometry and X-ray diffraction. We additionally provide an effective medium approximation (EMA) fit that greatly simplifies future macroscopic devices based on the underlying PCM nanorod geometry.

Authors: Lee Kil-yong , Lee Jaeim , Park Youn Young , Kim Hyung-Jin , Oh Seong Taek
Published: October 2023

Background

Small circular staplers possess the advantage of being relatively easy to use when compared to larger circular staplers. However, there is some contention as to whether the use of small circular staples in colorectal surgery increases the incidence of anastomotic strictures. This study aimed to determine whether the frequency of anastomosis site stricture formation differs depending on stapler size when performing anastomosis in colorectal surgery.

Methods

Patients who underwent surgery for colon or rectal disease between June 1, 2009, and December 31, 2021, and who had circular staplers used for the formation of intestinal anastomoses post colectomy were included in our study. Propensity score matching with a 1:1 ratio using logistic regression was performed. The primary outcome was the anastomotic stricture rate, and the secondary outcome was total anastomotic complications.

Results

A total of 875 patients who were operated on by surgeons using 28/29-mm and 25-mm circular staplers were included. After propensity score matching, 106 patients were assigned to each group. Anastomotic strictures occurred in two cases (1.9%) from the 25-mm group and in four cases (3.8%) from the 28/29-mm group. There were no statistically significant differences between the two groups (p = 0.683). Anastomotic complications were observed in two cases (1.9%) from the 25-mm group and in six cases (5.7%) from the 28/29-mm group; no statistically significant differences were found (p = 0.280).

Conclusion

Circular stapler size does not influence anastomotic stricture formation in colorectal surgery.

Authors: Ferreira Matheus Souza , da Silva Zilda Pereira , de Almeida Marcia Furquim , Alencar Gizelton Pereira
Published: October 2023

Background

Previous studies conducted in Europe and North America addressing the relationship between self-rated health and parenthood offer inconsistent results, with effects ranging from nonsignificant to significant and in opposite directions. The aim of the present study was to explore the relationship between parenthood and self-rated health (SRH) among women in Brazil (a country with strong inequalities) considering the time interval from the last delivery in the analyses, as proposed in previous studies set in Sweden.

Methods

The study used data from cross-sectional National Health Surveys in Brazil conducted from 2013 to 2014 and 2019 to 2020 with selected groups of 20,046 and 25,100 women for whom complete data were available on the variables of interest. The primary outcome was self-rated health measured on a five-point scale. Partial proportional odds models were employed.

Results

Compared to women that were not a parent, primiparous women whose delivery was within less than one year had a lower likelihood of worse SRH (OR (95% CI): 0.58–0.84 in 2013, and 0.64–0.94 in 2019), whereas multiparous women whose last delivery was more than one year earlier had greater likelihood of worse SRH (OR (95% CI): 1.08–1.27 in 2013, and 1.21–1.39 in 2019).

Conclusions

An association was found between parenthood and SRH among Brazilian women. Considering the epidemiological relevance of SRH, different aspects of parenthood concerning parity and time since the last delivery should be considered in further analyses.
Influence of body shape on health-related quality of life in Korean adults: The mediating effect of self-rated health
Authors: Her Eun Sil , Park Jung Kyu , Oh Yun Kyoung
Published: October 2023

A Body Shape Index (ABSI) predicts mortality independent of body mass index and had a negative relationship with self-rated health (SRH), which had a positive effect on the EuroQol (EQ)-5D index. This study aimed to investigate the relationship between ABSI and the EQ-5D index and to verify the mediating effect of SRH in Korean adults. This study included 13,381 participants aged ≥20 years from the 7th (2016-2018) Korean National Health and Nutrition Examination Survey (KNHANES). The participants were classified into tertile groups based on the ABSI (T1, T2, and T3 groups). Demographic characteristics, health-related factors, ABSI, SRH, and EQ-5D scores were evaluated. Women (p<0.001), rural areas (p<0.001), married persons (p<0.001), low education level (p<0.001), low income (p<0.001), and older age (p<0.001) were higher in the T3 group. The monthly drinking (p<0.001), current smoking (p<0.001), and mental stress rates (p<0.001) were the highest in the T1 group. The overall average SRH scores and EQ-5D index were 3.08 points and 0.94 points, respectively. ABSI and SRH (r = -0.161, p<0.001) and ABSI and EQ-5D (r = -0.229, p<0.001) showed a negative correlation. However, SRH and EQ-5D scores (r = 0.433, p<0.001) were positively correlated. The overall effect of the independent variable ABSI on the dependent variable EQ-5D was -0.959. SRH partially mediated the effect of ABSI on EQ-5D (indirect effect coefficient = –0.200). These results can be used as basic data to develop strategies and programs to improve health-related quality of life by adjusting ABSI and SRH.

Authors: Zuo Yuanyuan , Che Lixuan , Zhang Liping
Published: October 2023

Robotics education is important in training children’s thinking, practical, and innovation abilities. It is significant to stimulate children’s interest in learning and improve their learning quality. The existing research has not paid attention to the application of robotics education in children. It is necessary to stimulate children’s interest in learning. This paper will take senior kindergarten students as the research object. It analyzes the application of the Vector Space Model (VSM) in robotics course development. The research and development of children’s robotics courses incorporating Artificial Intelligence technology are based on the survey results of robotics courses offered by 38 kindergartens in Baoji City. An automatic document classification system based on VSM is designed to assist in compiling robotics teaching textbooks. Finally, the system performance is tested. The results show that about 24% of kindergartens offer robotics courses, and 76% do not. Besides, 70.14% of teachers support the establishment of children’s robotics courses. The classification effect of the VSM system is better than that of Chinese documents. This system performs better than the automatic document classification system based on Term Frequency–Inverse Document Frequency. Its classification accuracy, recall, and F1 value are all above 85%. The development of the robotics course provides a better teaching environment for teaching young children about AI and robots. The robotics education discussed in this paper is a hot spot in the current curriculum reform and is of great significance to the development and innovation in early childhood education.

Introduction

Malaria in pregnancy is a global public health problem with the majority of its impact seen in sub-Saharan Africa. Pregnant women with malaria infection are at risk of adverse maternal outcomes. In Ghana, malaria in pregnancy accounts for about 17.6% of outpatient department attendance. Ashanti region is among the three regions with the highest malaria prevalence in pregnancy, particularly in the Ejisu Municipality. The study, therefore, assessed the prevalence and determinants of malaria infection among pregnant women seeking antenatal care at the Ejisu Government Hospital in Ghana.

Methods

A cross-sectional study design with a convenience sampling technique was used to select 140 respondents for the study. Primary data such as age and residence of respondents were collected using a questionnaire and secondary data such as gestational age and Sulphadoxine Pyrimethamine (SP) administration were collected from clients’ maternal health record booklet. Bivariate and multivariate logistic regression analysis were used to assess the association between the malaria infection and the independent variables, and a p-value of < 0.05 was considered statistically significant.

Results

The overall prevalence of malaria in pregnancy was 24 (17.1%). Most of the respondents had received counselling and health education 126 (90%), two or more doses of SP 95 (87.2%), Insecticide Treated Net (ITN) 99 (70.7%) and were sleeping under ITN 104 (74.3%). Multivariate logistic regression analysis showed a statistically significant association between malaria infection and sleeping under ITN (AOR = 0.05; 95% CI = 0.01–0.28, p< .001), the use of insecticide mosquito spray (AOR = 0.27; 95% CI = 0.09–0.84, p = .045) and reason for not using ITN due to the use of other preventive measures (AOR = 0.06; 95% CI = 0.01–0.61, p = .017).

Conclusion

There was a high prevalence of malaria infection among study respondents despite the high usage of preventive measures for malaria in this study. It is therefore crucial that stakeholders in malaria control identify effective strategies to curb malaria transmission globally.

Published: October 2023

Sea cucumbers, belonging to the phylum Echinodermata, are known to possess valuable bioactive compounds that have medicinal properties. In several countries, such as Korea, China, and Japan, they are cultured in the aquaculture industries for food and medicinal purposes. Research has shown that different species of sea cucumbers each possesses unique medicinal values. As a result, we strive towards finding species with better health resilience in aquaculture system to be cultured for nutritional and medicinal purposes. In this paper, we compared the physiological and immunological parameters of three species of sea cucumbers, Cucumaria frondosa (C. frondosa), Isostychopus badionotus (I. badionotus), and Pentacta pygmaea (P. Pygmaea) from the waters of the eastern United States as they have not been studied extensively. Four different cells of sea cucumbers, phagocytic, red spherule, white spherule, and vibratile cells, that contribute to their immunity were counted. C. frondosa exhibited the highest concentrations of phagocytic cells, white spherule cells, and vibratile cells, compared to the two other species. Due to its high phagocytic cell concentration, the highest phagocytic capacity was seen in C. frondosa although it was not statistically significant. We also observed that C. frondosa had the highest total cell count and the highest concentration of coelomic protein among the three species. Lastly, C. frondosa possessed the highest lysozyme activity. Taken together, we concluded that C. frondosa is the best of the three species compared to be reared in the aquaculture systems for use in the food and biomedicine industries due to its immunological and physiological properties.
Maternal postnatal confinement practices and postpartum depression in Chinese populations: A systematic review
Authors: Yang Xiao , Qiu Mujie , Yang Yichun , Yan Junlin , Tang Kun
Published: October 2023

Background

The postpartum period is critical for maternal health status after childbirth. The traditional Chinese postpartum confinement practice, “doing-the-month”, is considered especially effective in helping mothers recover during the postpartum period. However, research has not provided evidence to confirm its benefits. Postpartum depression is a common postpartum disease that seriously threatens maternal health. The systematic review aims to explore the association between “doing-the-month” and postpartum depression in the Chinese female population and to provide a scientific foundation for evidence-based postpartum maternal care.

Methods

Five databases (PubMed, Embase, Web of Science, Scopus, Cochrane, PsycINFO, and Web of Science) were searched according to the protocol (INPALSY202320102). The JBI assessment tool was used to assess the quality of the included studies.

Results

Sixteen quantitative studies from China and Chinese female immigrants in other countries, including 15 cross-sectional studies and 1 randomized controlled study, were identified. Four studies indicated that “doing-the-month” rituals reduced postpartum depression risk while 2 studies showed opposite results; 10 studies did not show a significant association between “doing-the-month” practices and postpartum depression.

Conclusion

There is conflicting evidence regarding the association between “doing-the-month” and the likelihood of developing postpartum depression. Some studies have explored the impact of family ties, particular rituals, and specific stressors during the postpartum period on the occurrence of postpartum depression in Chinese women. According to current research, “doing-the-month” practice failed to show a significant protective effect on postpartum depression in the Chinese maternal population. Evidence-based medical health education for the Chinese postpartum female community is urgently needed.
Understanding and optimizing fish counting techniques based on electrical impedance measurements
Authors: Nowak Lukasz J. , Lankheet Martin
Published: October 2023

Sustainable aquatic resources management requires reliable methods for fish detection in various environmental conditions. Herein, we study fundamental mechanisms underlying the application of electrical impedance measurements in this regard. We present results of experimental studies conducted in laboratory conditions using a low-cost impedance measurement circuit, as well as the corresponding numerical models. We also present evaluation results of a newly developed, real-time detection algorithm based on adaptive thresholding. The numerical model was validated by extracting fish tracks in 3D space from the experimental datasets, and then comparing the calculated versus measured impedance values as functions of fish coordinates in time. Numerical predictions closely resemble the experimental data. The detection sensitivity and specificity values determined for various settings exceeded 90%. Electrode width to spacing ratio is demonstrated to be a crucial parameter influencing the system sensitivity distribution. The introduced approach can constitute a framework for designing electrical impedance-based fish counting systems.

The present study explores the combustion-mediated sol–gel preparation of the cobalt-doped ZnO (Co/ZnO) nanohybrids. The characterization results of as-prepared samples were investigated using analytical instruments like FTIR, XRD, XPS, SEM, UV-Vis DRS, BET, and TGA. The doping of cobalt into ZnO was achieved at a lower particle size (21.3 nm) than the pure ZnO (29.6 nm). We observed that the Co-doped ZnO grain size seems to be in abundance and diversity than that of the undoped ZnO. Further examination was carried out with photocatalytic degradation of acid red (AR) dye under visible light illumination and antibacterial performance over Spingomonous pausimobilis and Streptococcus pyrogenes to assess the catalytic performance of the prepared Co/ZnO nanohybrid. The photocatalytic degradation results from the optimum reaction conditions are 150 mg of catalyst loading, pH 2, and 10 ppm of initial AR dye concentration, and the complete degradation of AR dye in 120 min. The antibacterial performance of the Co/ZnO nanohybrid was measured and was found to be 25 and 16 mm for S. pausimobilis and S. pyrogenes, respectively, with respect to the control chloramphenicol.

The current study was aimed to develop a low cost HPLC method for determination of caffeine content in coffee samples in some coffee shops in Jeddah local market. Caffeine was extracted with water and separated through ZORBAX Eclipse XDB C-18 column using methanol/water (40:60) as mobile phase. The average peak response time for caffeine was 2.747 min with a relative standard deviation of 1.061. The proposed assay was able to detect caffeine in the concentration range from 5 to 45 ppm with limits of detection (LOD = 3σ/b) and quantification (LOQ = 10σ/b) of 1.086 and 3.619 ppm using two-channel UV detector set at 274 and 264 nm with correlation coefficient (R
2) of 0.9996, respectively. The assay was adopted for the determination caffeine content in 30 coffee samples collected from eight brand coffee shops and from local market. Each sample was injected in triplicate (n = 3) and the average and confidence limit of the mean were calculated. The concentration of caffeine in coffee brand shops varied from 513.82

Multiple Differenzierung und Wandel. Der Beitrag der evolutionär-institutionalistischen Perspektive
Authors: Mölders Marc
Published: October 2023

Theorien multipler Differenzierung haben Konjunktur. Sie teilen die Annahme, die Gegenwartsgesellschaft sei durch mehr als eine Differenzierungsachse (z. B. funktionale Differenzierungodervertikale Ungleichheit) charakterisiert. Solche Theorien thematisieren Anregungen sozialen Wandels höchst unterschiedlich. Der Beitrag unterscheidet drei Ausprägungen: (1) Anregungen als von eher historischem Interesse; (2) als inflationärer Dauerzustand; (3) als durch spezifische Modi (Kritik/Kooperation) ermöglicht. Die evolutionär-institutionalistische Perspektive Seth Abrutyns stellt demgegenüber ein Theorieangebot dar, dasmultiple Differenzierung auch als Ergebnis der Gestaltungsarbeit institutioneller Entrepreneureauffasst. Sie verzahnt multiple Differenzierung und Wandel unmittelbar. Dabei stellt sie die Überzeugungsarbeit solcher Wandelarchitekten in den Vordergrund und spielt Gestaltung und Evolution nicht gegeneinander aus. Abrutyns Rekonstruktion stoppt kurz vor der Gegenwartsgesellschaft. Hieran anschließend beleuchtet der Beitrag philanthropische Organisationen als zeitgenössische institutioneller Entrepreneure.
Interpersonal Trust in Adolescents With Borderline Personality Disorder: Comparisons With Healthy and Psychiatric Controls
Authors: Sharp Carla , Venta Amanda , McLaren Veronica
Published: October 2023

The aim of the current study was to utilize a well-known trust versus lottery paradigm to evaluate interpersonal trust in adolescents with borderline personality disorder (BPD). The study included 126 healthy controls, 59 inpatient adolescents with a diagnosis of BPD, and 137 inpatient adolescents without BPD. Alongside diagnostic measures, a questionnaire-based measure for assessing trust beliefs was administered to probe group differences in trust beliefs and associations between game behavior and trust beliefs. No main effect for group or condition was found. A significant interaction of trial and group was noted, suggesting that across games, psychiatric controls demonstrated the steepest increase in trust over time, followed by the BPD and healthy control groups. Healthy controls evidenced significantly higher levels of trust beliefs compared to BPD and psychiatric controls. Reasons for nonreplication of previously demonstrated anomalous game behavior in adults in this adolescent sample are discussed.
Atypical Neural Plasticity and Behavioral Effects of Trustworthiness Learning in Borderline Personality Disorder Features
Authors: Fertuck Eric A. , Fischer Stephanie A. , Melara Robert D.
Published: October 2023

This study distinguishes interpersonal trust learning with a novel trust learning paradigm in participants high (H-BPD) and low (L-BPD) in BPD features. Neutral faces were paired with trust-relevant behaviors in four conditions: trustworthy, untrustworthy, ambiguously trustworthy, and mixed trustworthiness. After training, participants rated faces on untrustworthiness as electroencephalographic measures were recorded. H-BPD rated neutral faces as significantly more untrustworthy than L-BPD at both time periods. Negative and ambiguous trustworthiness pairing conditions led to higher ratings of untrustworthiness, whereas trustworthy and mixed descriptors led to lower ratings of untrustworthiness. Learning enhanced the amplitude of an early sensory event-related potential (ERP) component (i.e., P1) for both groups. The slow-wave ERP, an index of sustained attention, revealed greater focus after learning to trustworthy descriptors in H-BPD and to untrustworthy descriptors in L-BPD. H-BPD utilized greater effort to overcome an inherent mistrust bias and L-BPD to overcome unexpected untrustworthy information.

Skeletal muscle is a plastic tissue with contractile capacity to generate force. Muscle mass plays a crucial role in determining muscle strength. However, the diversity of genetic features among individuals can significantly influence muscle mass development. Among these genetic factors are polymorphisms in the ace gen which codify for angiotensin-converting enzyme (ACE), an enzyme that belongs to the renin-angiotensin system (RAS). In addition, there are single nucleotide polymorphisms (SNP) of angiotensin-converting enzyme 2 gene (ace2), that codify for an enzyme that is part of the non-classical RAS axis, which has recently been shown to prevent atrophic and fibrotic processes in skeletal muscle. However, the influence of ace2 SNPs on skeletal muscle strength is unknown. This research aims to study the association between the SNPs rs879922, rs2285666, and rs1978124 of the ace2 gene with isometric muscle strength in sedentary young adults. Thirty-eight healthy sedentary men (18-25 years old) who met the exclusion criteria were recruited for the study. Anthropometric measurements were then taken, and a venous blood sample was extracted to determine the allele of each polymorphism studied. Skeletal muscle strength was measured using a handgrip dynamometer. Our results show no differences in grip strength between alleles of ace2 polymorphisms nor in comparing the muscle strength between the most common haplotypes. We can conclude that there is no association of rs879922, rs2285666, and rs1978124 ace2 polymorphisms with isometric grip strength in sedentary young adults, nor is there an association between ace2 haplotypes and muscle strength.
Determination Of Optical Constant of a Clear Glass Material for Accurate Daylighting and Solar Heat Gain Assessment Using Spectrophotometer Measurements
Authors: Khoukhi Maatouk , Khatib Omar Al
Published: October 2023

Many qualities make glass attractive, as it is transparent, chemically inert, environmentally friendly, sustainable, strong, easily available and relatively cheap. Recently, many researchers have been interested in designing the buildings to get the benefit from daylight inside, which saves a lot of building consumption for artificial lighting, which gives visual and thermal comfort and also contributes to reducing costs. The complex refractive index of glass is a very crucial concept because it determines not only how much light is reflected and transmitted, but also its angle of refraction in glass. The optical constants of glass material are very useful for determining its radiative properties, as well as for selecting the appropriate thin-film coatings on a glass substrate. The objective of this study is to calculate the real part (n) and the imaginary part (k) of the complex refractive index of a clear glass material using a simple method based on the reflectivity and transmissivity measurements. In this study, the parts n and k are derived from the equations of the reflectivity at near zero incidence and transmissivity at normal incidence by using Shimadzu IR-70 Spectrophotometer and Cary 5E Spectrophotometer apparatuses. The real and the imaginary parts of the complex refractive index of the glass sample obtained in the present study are in very good agreement with Rubin’s data. Although, a direct comparison between different samples is not possible, due to the difference in manufacturing process and material composition.
