IntroductionUnder the impacts of high intensity human activities, mangrove natural protected areas are pivotal strategies for biodiversity conservation and play a significant role in preserving bird diversity. Mangrove natural protected areas in Guangdong Province, China, lie along the migratory path of the East Asian-Australasian Flyway, serving as breeding, feeding, and resting grounds for birds. Variations in bird responses to environmental factors are significant.MethodsTo comprehensively understand these variances, redundancy analysis was employed, focusing on bird diversity surveys conducted from March 2022 to February 2023 in natural protected areas of Guangdong to examine how driving factors such as mangrove habitat landscape, community structure, water quality, and soil sedimentation affected the diversity of avian species.ResultsThe findings were as follows: (1) A total of 193 bird species spanning 17 orders and 53 families were documented, including 74 songbirds, 60 wading birds, 27 swimming birds, 17 climbing birds, 10 raptors, and 5 terrestrial birds. (2) Regarding the impact of simple effects on all bird species, aquaculture pond area, mangrove extent, and mudflat area emerged as significant factors driving bird diversity, with explanatory rates of 31.0%, 28.9%, and 20.3%, respectively. Notably, the aquaculture pond area was the main driver of bird diversity, with an explanatory rate of 31.0%. (3) Mangrove extent has emerged as a pivotal factor shaping the songbird diversity, climbing birds, raptors, and terrestrial birds, whereas the aquaculture pond area was pivotal for wading birds, swimming birds, and others.DiscussionTo enhance mangrove bird diversity protection, management agencies overseeing natural mangrove protected areas should adopt science-based approaches when managing mangrove, mudflats, and aquaculture pond areas in mangrove forest protection and restoration plans. This would prevent extensive mangrove planting, which encroaches on non-mangrove habitats. Additionally, the scientific management of aquaculture ponds should accommodate diverse bird habitats through measures, such as water level adjustments.
The effects of perceived sport environment on sport gains of Chinese university students: chain mediation between physical activity behavior and sport learning self-efficacy
Authors: Wu Liang , Gao Jia , Xiang Jun 
Published: December 2024

IntroductionSports gains reflect the sports development of college students, which is a direct reflection of the quality of school sports work, while the perception of sports environment, physical activity behavior, and self-efficacy in sports learning are closely related to their sports gains, which directly affects their effectiveness and interest in sports learning.ObjectiveTo investigate the effects of perceived sports environment on Chinese college students’ sport gains, and to verify the mediating roles of physical activity behavior and self-efficacy in sport learning.MethodsA survey of 2,207 Chinese university students was conducted using the sport environment perception scale, sport gain scale, physical activity behavior scale, and sport learning self-efficacy scale.Results(1) There were significant differences in age and gender between college students’ perceptions of sport environment, sport gains, sport exercise behavior, and sport learning self-efficacy, and the mean scores of each scale were better for male students than for female students. (2) Perception of sports environment was significantly positively correlated with sports gain, and perception of sports environment had a direct positive effect on sports gain. In addition, sport environment perception positively predicted physical activity behavior and sport learning self-efficacy; physical activity behavior significantly predicted sport learning self-efficacy and sport gains; physical learning self-efficacy was a significant positive predictor of sport gains. (3) Physical activity behavior and physical learning self-efficacy played a significant chained mediating role between perceived physical environment and physical gains. These results are important for promoting physical education learning outcomes among college students and provide a theoretical basis for developing interventions. However, there are limitations to this study, such as the specificity of the sample and the self-reported data used. Future research could expand the sample and utilize multiple assessment methods to validate these results.

Published: December 2024

Abstract: Percutaneous nephrolithotomy (PCNL) is the primary surgical management for kidney stones larger than >20mm. The success of this procedure is assessed by monitoring the stone free rate (SFR). Currently, SFR can be predicted through validated scoring systems such as Guy’s stone score and S.T.O.N.E. nephrolithometry score. This study aimed to compare Guy’s stone score and S.T.O.N.E. nephrolithometry score in predicting SFR after PCNL at Prof. Dr. R. D. Kandou Hospital Manado. This was an observational and analytical study with a cross-sectional design. Data collection was conducted through patients’ medical record data. Data analysis was performed using the Fisher’s Exact Test and the independent t-test through SPSS Statistic Version 26 for MacOS. The results showed that there was no statistically significant relationship between Guy’s Stone Score and SFR after PCNL (p=0.706). The S.T.O.N.E. nephrolithometry score also showed no significant relationship with SFR after PCNL (p=0.514). In conclusion, both Guy’s stone score and S.T.O.N.E. nephrolithometry score do not have significant impact on predicting stone free rate in patients with kidney stone at Prof. Dr. R. D. Kandou Hospital Manado.

Published: December 2024

The Geometry optimized has been investigated at ground state, B3LYP, 6-311G basis sets with density functional theory (DFT). Theoretical characteristics, like as shape and the HOMO-LUMO gap determined by DFT simulations, help the discovery of donating sites. Global reactivity characteristics of folic acid at the B3LYP/6-311G level have been computed in this work. The global reactivity descriptors include global softness (S), global hardness (η), global affinity (A), ionization potential (I), electro negativity (χ), chemical potential (μ), global electrophilicity index (ω), and global hardness (η). Theoretical spectrograms for the UV and IR spectrum were also constructed at B3LYP values.

Published: December 2024

This study aimed to determine the effect of using a virtual anatomy system (VAS) on student learning with regard to reproductive system with respect to the acquisition of misconceptions. This study used an experimental method by comparing the results of the class learning using virtual laboratory media with a control class. The result showed that a significant increase in learning outcomes in the experimental class 77.73 mean compared to the control class mean of 69.5. The magnitude of the increase in learning outcomes (N-gain) of the experimental class was 0.67 within the medium category beside control class. It can be seen that the level of misconceptions in the experimental class was 11.6% smaller than the control class at 37.6%.
Refractive Outcome, Lens Power Calculation, and Surgically Induced Astigmatism After Four-Flanged Intrascleral Intraocular Lens Fixation
Authors: Schranz Markus , Lisy Marcus , Dimakopoulou Ioanna , Danzinger Victor , Schartmüller Daniel , Abela-Formanek Claudette 
Published: December 2024

Purpose
To evaluate the refractive prediction error of common intraocular lens (IOL) power calculation formulas in patients who underwent intrascleral IOL fixation using the four-flanged technique.

Methods
This prospective, longitudinal, single-site, single-surgeon study's setting was the Department for Ophthalmology and Optometry, Medical University of Vienna, Austria. Patients who received IOL implantation via the four-flanged technique were followed up to 3 months after the operation. Refraction was measured using the Early Treatment of Diabetic Retinopathy Study visual acuity test at 4 m. Lens decentration, tilt, and aqueous anterior chamber depth were evaluated using anterior segment optical coherence tomography. The SRKT, Holladay 1, and Hoffer-Q formulas were used to assess prediction error (PE) and absolute error (AE). Correlations between axial length, keratometry, and white-to-white distance were subsequently evaluated.

Results

A total of 28 eyes of 28 patients were examined in this study. The application of all formulas resulted in a hyperopic PE (SRKT: 0.35 ± 0.86 diopters [D], Holladay 1: 0.36 ± 0.78 D and Hoffer-Q: 0.37 ± 0.73 D). There was no variation between the PE of different formulas discovered (
P
> .05). The AE was within 0.50 D in 54% to 61% and within 1.00 D in 79% of eyes, depending on the formula used. Furthermore, Cochrane's Q test detected no significant distinctions between formulas (
P
> .05). The PE of each formula demonstrated a significant correlation to the axial length of the eyes (
P
< .05). The correlation estimates ranged from −0.25 D/mm to −0.39 D/mm, subject to the applied formula.

Conclusions
This study demonstrates that the four-flanged technique for scleral IOL fixation yields reliable outcomes. PE was closest to zero using the Hoffer-Q formula, although there was no statistically significant difference compared to the other formulas. Axial length emerged as the most pertinent factor for PE. Short eyes resulted in a more hyperopic outcome, whereas longer eyes resulted in a more myopic outcome than intended. This myopic and hyperopic shift was due to the standardized surgical technique with an externalization of the haptics 2.5 mm behind the limbus resulting in a consistent aqueous anterior chamber depth across all eye lengths, coupled with a reduction or increase in the distance from the IOL to the macula, which is dependent on the length of the eye.

Transepithelial Versus Epithelium-off Photorefractive Keratectomy in High Compound Myopic Astigmatism: A Contralateral Eye Study
Authors: Peyman Alireza , Ghoreishi Mohammad , Babaei Leila , Noorshargh Pegah , Forouhari Ali , Pourazizi Mohsen 
Published: December 2024

Purpose
To compare clinical outcomes of transepithelial photorefractive keratectomy (t-PRK) and conventional epithelium-off PRK (PRK) in patients with high compound myopic astigmatism.

Methods
Sixty eyes of 30 myopic individuals with at least −2.50 diopters (D) of spherical equivalent and 3.00 D of cylindrical refractive error were enrolled in the study. Both eyes of each patient were randomly assigned to either the t-PRK method or epithelium-off PRK as a matched contralateral control group. Refractive outcomes were evaluated 6 months after surgery.

Results

At the 6-month visit, cylindrical refractive error magnitude was lower in the t-PRK (0.51 ± 0.29 D) compared to the PRK (0.67 ± 0.30 D) group (
P
= .04). The residual astigmatism was 0.50 diopters or less in 23 eyes (76%) in the t-PRK group and 15 eyes (50%) in the PRK group. In vector analysis using the Alpins method, t-PRK resulted in a significantly higher percentage of success of astigmatic surgery (84.68 ± 8.95 in t-PRK versus 79.46 ± 10.88 in PRK,
P
= .04). Additionally, there was a marginal advantage for the t-PRK group regarding index of success of astigmatism surgery (
P
= .06) and absolute (
P
= .08) and arithmetic (
P
= .07) angles of error compared to the PRK group. Both groups had an equal safety profile.

Conclusions
T-PRK is more accurate for astigmatic correction in high astigmatism than conventional PRK. Both t-PRK and PRK are comparable respecting safety and efficacy.

Effects and Related Factors of Short-time Accommodation Training on Measuring Consistency of InnovEyes Sitemap, Autorefraction, and Subjective Refraction
Authors: Jin Chengcheng , Wang Shiyuan , Ye Hehua , Wei Ruihua , Dong Yuan , Zhao Peiquan 
Published: December 2024

Purpose
To evaluate effects and related factors of short-time accommodation training on measuring consistency of InnovEyes Sitemap (Alcon/WaveLight; Alcon Laboratories, Inc), NIDEK ARK-1 autorefractor (Nidek Corporation), and subjective refraction (SR).

Methods
One hundred adults (100 eyes) with myopia aged 17 to 40 years were enrolled. Refraction was obtained by InnovEyes Sitemap, autorefraction, and SR in a randomized order. Refractive data of InnovEyes Sitemap were grouped into two groups without and with application of a 2.00 diopter (D) flipper before InnovEyes Sitemap.

Results

The average difference in spherical equivalent (SE) between InnovEyes Sitemap and SR (autorefraction) decreased from −0.56 ± −0.41 D in the without accommodation training group to −0.29 ± −0.14 D in the with accommodation training group, with 95% CI of limits of agreement (LOA) shrinking dramatically (InnovEyes Sitemap–SR: −1.39 to 0.27 vs −0.71 to 0.14 D; InnovEyes Sitemap–autorefraction: −1.23 to 0.40 vs −0.69 to 0.40 D). Furthermore, short-time accommodation training significantly improved the consistency of myopia measurements, with the proportion of SE differences within 0.50 D between InnovEyes Sitemap and SR significantly increasing from 56% to 88% (
P
< .001). Meanwhile, J0 and J45 showed no significant difference (
P
> .05) with similar LOA among three techniques in both groups. SE difference of InnovEyes Sitemap (with accommodation training group minus without accommodation training group) was significantly correlated to SE difference between SR and habitual glass refraction (β = −0.312,
P
= .001), lens thickness (β = 0.262,
P
= .006), and axial length (β = 0.199,
P
= .037).

Conclusions
Short-time accommodation training could promote spherical consistency but not deteriorate cylindrical agreement among InnovEyes Sitemap, autorefraction, and SR, and this effect showed more effective in eyes with more undercorrected myopia in habitual prescription, thicker lens, and longer axial length.

Considérer le nudisme -et donc le naturisme- comme l’un des beaux-arts écosophes à travers le prisme des photographies de foules nues rassemblées par Spencer Tunick dans des lieux incongrus
Authors: Lafargue Bernard 
Published: December 2024

Cet article s’appuie sur une approche esthétique des photographies des milliers de foules nues, que Spencer Tunick « installe » depuis trois décennies dans des lieux incongrus, pour considérer le nudisme comme l’un des beaux-arts. Se mettre nu est un art de vivre ; une manière de se parer qui, tout en visant à rapprocher les êtres humains de tous les autres êtres vivants, cherche à substituer la paix perpétuelle à la lutte pour la vie. Selon les époques, cet art de vivre invente plusieurs figures, qui oscillent entre le récit d’un paradis chaste et celui d’un paradis pansexuel.
