Published: October 2023

BackgroundFalls place a heavy burden on older adults and families, and there was little research on the relationship between falls and depressive symptoms among older adults in China. This study is designed to examine the association between falls and depressive symptoms in Chinese older adults.MethodsThis study was based on 9,539 data sets from the China Health and Retirement Longitudinal Study (CHARLS) in 2018. The 10-item Center for Epidemiologic Studies-Depression Scale (CESD-10) was used to access depressive symptoms in older adults. A logistic regression model was used to calculate multivariate odds ratios (ORs) and 95% confidence intervals (CIs) for falls and depressive symptoms, adjusted for possible confounders. The Classification and regression tree (CART) demonstrates the prediction of the target variable values based on other variables.ResultsIn this study, 9,539 older people were selected: 60–69 years old accounted for 63.0%, 70–79 years old accounted for 29.7%, and 80 years old and above accounted for 7.3%. Male accounted for 49.7% and female for 50.3%. The rate of falls among older adults was 21.4%, and the rate of depressive symptoms was 33.9%. Adjusted ORs (OR = 1.37, 95% CI: 1.23, 1.53) showed a significant association between falls and depressive symptoms among older adults. Subgroup analysis revealed that this association was statistically significant across male (OR = 1.29, 95% CI: 1.23, 1.53) and female (OR = 1.42, 95% CI: 1.23, 1.64), 60–69 aged (OR = 1.38, 95% CI: 1.19, 1.60) and 70–79 aged (OR =1.42, 95% CI: 1.16, 1.74), rural (OR = 1.42, 95% CI: 1.25, 1.61), &lt;15,000 CNY (OR = 1.35, 95% CI: 1.19, 1.54) and more than 25,000 CNY (OR = 1.42, 95% CI: 1.09, 1.85). Additionally, The CART model showed that the probability (73.0%) of falls was highest among older adults with depressive symptoms who self-rated poor health and female gender.ConclusionsThis cross-sectional study demonstrated a significant association between falls and depressive symptoms in Chinese older adults. The findings provide some evidence and support for risk monitoring, screening for depressive symptoms, and early prevention in the high-risk older population.
Maximizing the disinfection effectiveness of 254 nm UV-C light with a special design unit: simulation and experimental approaches

Published: October 2023

We propose a special design enclosure device that promotes isotropic distribution of germicidal UV-C light for the effective disinfection of difficult to reach surfaces. We used experimental and computational approaches to investigate the disinfection efficacy of this device against Escherichia coli and Listeria innocua. Stainless steel, Copper metal, and a Copper polymer were used as solid substrates of varying roughness and hydrophobicity. Bacteria reductions of up to 6.9 log CFU were achieved at various locations relative to the UV-C source after 3 min of treatment (20–990 mJ/cm2 cumulative fluence depending on the location). Inactivation kinetics was nonlinear and followed the Weibull model (0.77 ≤ R2 ≤ 0.97). Optical ray tracing simulation was used to generate maps of spatial light distribution, which were then coupled with microbial inactivation kinetics to create spatial maps of inactivation. The modeling approach used accurately predicted microbial inactivation at various locations, with only small discrepancies (±8%) between predicted and experimental data. These findings demonstrate that the proposed device is suitable for disinfecting various hard to reach surfaces, with numerous possible applications in the food and healthcare industries. Additionally, the modeling approach used here can be used to aid in the design of a highly effective Ultraviolet treatment system.

Objective: To conduct a bibliometric analysis of the global snakebite literature to provide a reference for the future development of snakebite research.Methods: The Web of Science citation analysis tools, VOSviewer and CiteSpace V were used to carry out the bibliometric analysis of the literature and generate visualization maps.Results: The number of publications has increased at a considerably accelerated rate in the past 8 years. Nine distinct cooperation clusters were formed between institutions and countries. Keyword clustering yielded nine well-structured clusters covering two major topics, i.e., snakebite envenoming and antivenom. Burstiness detection revealed eight keywords with strong emergence, including neglected tropical diseases, Elapidae, Viperidae, and Russell’s viper, which have sustained popularity up to the present.Conclusion: Current research on snakebites has gradually garnered attention from the academic community. Cooperation papers between nations severely affected by snakebite and those with higher economic status received more attention. The continued exploration of therapeutic mechanisms, the development of antivenoms or alternative medicines, and primary prevention of snakebites to ensure the safety of populations in impoverished regions should be prioritized by international scholars. The epidemiological evidence and the timely translation of research findings should be valued by policymakers.

Selection of patients who may benefit from extracorporeal life support (ECLS) as a bridge to lung transplant (LTx) is crucial. The aim was to assess if validated prognostic scores could help in selecting patients who may benefit from ECLS-bridging predicting their outcomes. Clinical data of patients successfully ECLS-bridged to LTx from 2009 to 2021 were collected from two European centers. For each patient, we calculated Sequential Organ Failure Assessment (SOFA), Simplified Acute Physiology Score III (SAPS III), Acute Physiology and Chronic Health Evaluation II (APACHE II), before placing ECLS support, and then correlated with outcome. Median values of SOFA, SAPS III, and APACHE II were 5 (IQR 3–9), 57 (IQR 47.5–65), and 21 (IQR 15–26). In-hospital, 30 and 90 days mortality were 21%, 14%, and 22%. SOFA, SAPS III, and APACHE II were analyzed as predictors of in-hospital, 30 and 90 days mortality (SOFA C-Index: 0.67, 0.78, 0.72; SAPS III C-index: 0.48, 0.45, 0.51; APACHE II C-Index: 0.49, 0.45, 0.52). For SOFA, the score with the best performance, a value ≥9 was identified to be the optimal cut-off for the prediction of the outcomes of interest. SOFA may be considered an adequate predictor in these patients, helping clinical decision-making. More specific and simplified scores for this population are necessary.

Published: October 2023

Pinus pinea is widely distributed in the Mediterranean basin. In Portugal, it is predominantly located in the southwestern coastal area. Yet, there are also forest areas of Pinus pinea in inland southern Portugal. Four plots were settled to study the effects of soil chemical characteristics, air temperature and precipitation on Pinus pinea growth. In these plots, stand structure, soil texture, soil organic matter, soil content on macronutrients and micronutrients, air temperature and precipitation were analysed. The results indicate that the greatest growth was achieved in the plots with good availability of nutrients and the highest precipitation, whereas the lowest growth was observed in the plots with the lowest precipitation. There seems to be a trend toward the main limiting factor to Pinus pinea growth being the availability of water.

The research on how to reduce energy consumption and improve the efficiency of amorphous motors has extensive coverage. This study systematically investigates the influence of internal stress induced by impregnation curing and interference fit on the soft magnetic properties and loss characteristics of Fe80Co3Si3B10P1C3 (CAF4) amorphous alloy iron cores. The amorphous iron core samples undergo analysis through differential scanning calorimetry (DSC), transmission electron microscopy (TEM), X-ray diffraction (XRD), magnetic performance testing equipment, flexible pressure sensors, and magnetostriction testers. The CAF4 amorphous iron core after impregnation curing (AIC) exhibits the lowest loss of P1.2T,1.5 kHz = 22.8 W/kg when annealed at 260 °C, representing a 21% increase compared to the pre-impregnation curing (BIC) state. Within the commonly utilized interference fit range, the loss growth rate of CAF4 amorphous iron cores is lower than that of Fe80Si9B11 (1K101). Likewise, at a frequency of 50 Hz and an excitation of 1000 A/m, the magnetostriction coefficient of CAF4 is smaller than that of 1K101. Within the typical interference fit range, the magnetization performance of CAF4 amorphous iron cores surpasses that of 1K101, favoring lightweight and compact motor designs and reducing copper losses. Consequently, CAF4 amorphous iron cores exhibit significant advantages when employed in motors.
Kesatuan Jemaat Berdasarkan Ekaristi Analisa Sosial 1 Kor. 11:17-34:
Authors: Wibisono Hari Gunawan 
Published: October 2023

Surat 1 Korintus memberi gambaran akan perhatian Paulus terhadap jemaat Korintus. Salah satu pokok persoalan yang ingin disinggung oleh Paulus adalah mengenai rasa solidaritas dalam praktik Perjamuan Ekaristi. Solidaritas adalah semangat dasar yang terwujud dalam Tradisi Ekaristi. Akan tetapi semangat tersebut belum terlihat dalam tubuh jemaat Korintus. Penyebabnya adalah adanya perbedaan budaya, asal usul, dan status sosial yang sudah mengakar dalam kehidupan bermasyarakat. Perjamuan Ekaristi hadir sebagai lambang akan kesatuan tubuh jemaat yang dipersatukan melalui baptisan yang sama. Oleh karena itu, Ekaristi menjadi tindakan nyata seseorang, yang melalui baptisan, telah memperbaharui dirinya dengan semangat solidaritas sebagai kesatuan Tubuh Kristus. Hanya saja, adanya penekanan tentang perbedaan status sosial sebagai aturan bersama dalam Perjamuan Ekaristi di Korintus menggambarkan cara hidup yang tidak tepat sebagai sebuah jemaat.

Published: October 2023

In this study, surface quality and tangential cutting force and radial width (ae) and axial deep (ap)
parameters were investigated in the processing of white marble, which is a natural building material.
Five different white marbles were used in the experiments and the taguchi method was applied as the
test method. Depending on the number and level of parameters, the L9 orthogonal array was chosen.
Cutting forces and surface roughness data were collected for each marble. The optimal level and
contribution percentage of each parameter was determined by applying the analysis of variance with
the signal-to-noise (S/N) ratio. The Fr and Ra factors for all marbles were found to be ae:1 mm and ap:1
mm. Depending on the significance level, axial depth of cut (ap) was the primary effective parameter
(65-86% for Fr; 42-78% for Ra), while radial depth of cut was the secondary effective parameter (3-24%
for Fr; 16-35% for Ra). It can be said that the feed rate parameter was not an effective parameter in
general.As a result of regression analysis, a significant relationship of 83% was observed between Ra
surface roughness value and mineral grain size. Grain size has been the mineralogical-petrographic
feature affecting the surface quality of marbles.

Published: October 2023

Falling is a serious health risk that can even result in death, especially for the elderly. For this reason, it
is crucial to prevent falls and, in cases where prevention is not possible, to detect and intervene as soon
as possible. Smartwatches are an ideal tool for fall detection due to their constant presence, rich sensor
resources, and communication capabilities. The aim of this study is to detect falls in elderly people with
high accuracy using motion sensor data obtained from smartwatches. To achieve this, a dataset was
created consisting of falls and daily activities. Then, the feature vector was extracted which has
provided successful results in signal processing studies. Afterward, the dimensionality of the dataset
was reduced using an autoencoder-based approach in order to decrease the workload on smartwatches
and ensure more accurate and faster classification. The dataset was classified using machine learning
methods including naive Bayes, logistic regression, and C4.5 decision tree, and successful results were
obtained. Their performances were then compared. It was observed that reducing the dimensionality
had positive effects on both the classification accuracy and the computation time.

Published: October 2023

Abstract: Social networking sites (SNS) have become a trend nowadays and it was widely used by university students, however, the rapid expansion of the SNS has caused the time engaging with the technology to become excessive and lead to addiction and other negative consequences among the students. The purpose of this study was to test the motives of watching YouTube as predictors of students' addiction behavior through the Uses and Gratification (U&G) theory. This research adopts a quantitative method, through the online questionnaire. The study applied purposeful sampling, where the respondents who have watched YouTube and have a YouTube account were selected and generated 150 valid responses from the students at a private university in Klang Valley. The findings demonstrate that three motives (Passing Time, Enjoyment, and Information-seeking) are the predictors of YouTube addiction behavior among the students and different motives lead to different degrees of addiction. This study contributes to the U&G Theory as well as the literature on media consumption, for it benefits the parents, universities, and government in understanding the motives that influence media addiction among university students. Thus, strategies can be implemented to avoid excessive addiction which leads to negative social media outcomes.
