Published: February 2025

Purple-spotted bigeye is an economically important fish that is widely used by the community, resulting in intensive fishing and is thought to have caused pressure on resources which has an impact on changes in its biological structure. Based on this, research needs to be carried out to determine the size distribution, growth patterns and condition factors of Purple-spotted bigeye in the waters of the Makassar Strait. This research was carried out from April to June 2024 at the Paotere Makassar, Maros, and Macini Baji Fish Landing Sites in Pangkajene and the Islands. This research is classified as a quantitative type of research with survey methods and direct measurements in the field. The number of samples that were successfully measured was 725 fish, a combination of male and female fish with representation in small, medium and large sizes. Fish were measured to the length of the fork and weighed to determine the total weight of the fish. The results showed that the growth pattern of purple-spotted bigeye was negative allometric with b value of 1.4147 (b < 3) with length increase faster than weight increase, condition factor ranging from 0.242 to 2.837 (1.063 ± 0.379) and distribution of fork lengths around 34 .2-98.8 mm (72.44 ± 9.32 mm) with a weight ranging from 0.46-88.6 mg (34.27 ± 13.44 mg). Based on the value of the growth pattern, the purple-spotted bigeye is included in a condition of stressed resources.

Bullying merupakan perilaku untuk mempermalukan orang lain, dengan kebiasaan buruk yang dapat merugikan orang lain yang menimbulkan trauma, luka, bahkan sampai merenggut nyawa. Hal ini yang sangat meresahkan yaitu bahwa pelaku kasus bullying itu merupakan anak-anak dibawah umur yang masih sekolah dan terkadang korbannya adalah temannya sendiri. Peneliti ini bertujuan membahas dua fokus penelitian: pertama upaya penegakan hukum terhadap tindak pidana bullying yang dilakukan oleh anak dibawah umur; dan kedua, faktor penghambat penegakan hukum terhadap tindak pidana bullying yang dilakukan anak dibawah umur. Penelitian ini termasuk dalam kajian yuridis normatif dengan menggunakan pendekatan perundang-undangan, pendekatan konseptual, dan pendekatan sosiologis. Teknik pengumpulan bahan hukum dilakukan dengan studi pustaka terhadap bahan-bahan hukum. Dalam hal penegakan hukum terhadap anak yang melakukan tindak pidana bullying dilakukannya mediasi yang diselesaikan secara kekeluargaan atau diversi yang sampai melukai fisik maka sanksi ½ dari hukuman orang dewasa sebagaimana ketentuan Undang-Undang Nomor 11 Tahun 2012 tentang sistem peradilan pidana anak..
Travailler dans un organisme communautaire et accompagner un parent d’enfant placé : quelles pratiques sont privilégiées ?
Authors: Pelletier Émilie , Ross Frédérike , Noël Julie , Ummel Deborah 
Published: February 2025

Bien que peu documentées dans les écrits empiriques actuels, les interventions prodiguées par les personnes intervenant en milieu communautaire sont incontournables dans l’accompagnement des parents lorsqu’un enfant est placé par la Direction de la protection de la jeunesse. S’appuyant sur 28 entrevues individuelles semi-structurées, réalisées auprès de personnes travaillant au sein d’organismes communautaires du Québec, l’article présente leurs pratiques quant à l’accompagnement de parents au cours du processus de placement. Leurs propositions portent sur les habiletés au fondement de la création et du maintien du lien de confiance, sur la mise en valeur de l’évaluation globale de la situation du parent ainsi que sur les connaissances nécessaires pour soutenir la diversité des interventions requises. Le milieu communautaire, du fait de sa nature, met en place des pratiques novatrices et complémentaires au travail de la protection de la jeunesse. Ainsi, lorsque le parent le consent, la mise en place d’une collaboration intersectorielle apparaît essentielle pour que les parents d’un enfant placé par la Direction de la protection de la jeunesse puissent bénéficier de suivis cohérents et d’un continuum de services. Toutefois, pour que ces espaces de collaboration se matérialisent, l’expertise des personnes qui interviennent en milieu communautaire doit être reconnue.
A conceptual replication of the Psychological Typhoon Eye effect in the aftermath of the Petrinja earthquake in Croatia
Authors: Mertens Gaëtan , Dürrigl Marta 
Published: February 2025

Background
The Psychological Typhoon Eye (PTE) effect refers to the observation that those living in the epicenters of natural disasters or public emergencies exhibit lower levels of psychological distress than those living further away. The effect has been described in the aftermath of multiple public emergencies, including the 2008 Wenchuan earthquake. However, despite its potential importance for emergency relieve, this phenomenon has received little research attention and requires further replication. The goals of this study were to replicate the PTE effect using both the original items used in prior research and using the validated Depression, Anxiety, and Stress Scales (DASS).

Methods
A cross-sectional survey was conducted following an earthquake with a magnitude of 6.4 on the Richter scale that occurred in December 2020 in Petrinja, Croatia. The sample consisted of 316 participants living in Croatia at the time of the earthquake. Questionnaires were administered through an online survey, including the DASS, the items used in previous research, and questionnaires measuring general and earthquake-specific coping. Exposure to the earthquake was operationalized as the degree of devastation participants had experienced (i.e., the degree of structural damage to their home as assessed by local authorities). In line with previous work, we tested for an inverse relationship between the experienced level of devastation and the different measures of psychological distress (i.e., the items used in previous work and the DASS).

Results
We found no evidence for the PTE effect in our study. Instead, we observed a ripple effect, whereby those most affected by the earthquake showed the most psychological distress. We argue that the ripple effect, rather than the PTE effect, should be seen as the default psychological response pattern to natural disasters and emergencies.
Predictors of outcome among children with biliary atresia: a single centre trial
Authors: Ye Chaoxiang , Gao Wei 
Published: February 2025

Objective
This study aimed to investigate the predictive role of preoperative gamma-glutamyl transpeptidase (GGT) levels on the prognosis of neonatal biliary atresia (NBA) in patients who underwent the Kasai procedure.

Methods
A retrospective analysis was conducted of patients with NBA who underwent the Kasai procedure at our hospital from 2017 to 2021. Patients were categorized into high (GGT > 300 IU/L) and GGT inadequate (GGT ≤ 300 IU/L) groups based on preoperative GGT levels. The influence of GGT levels on NBA prognosis was evaluated by comparing clinical data, age at operation, jaundice normalization, and survival outcomes between the groups.

Results
A total of 74 patients with NBA were included, with 59 in the high GGT group and 15 in the GGT inadequate group. Ages at the time of the Kasai procedure ranged from 31 to 106 days, with a median of 61 days; the average weight was 4.8 ± 1.1 kg. Two years post-procedure, 56 patients (75.7%) survived with their native liver (P < 0.0001). At 3 months post-procedure, alanine aminotransferase (ALT) levels were significantly higher in the GGT inadequate group compared to the high GGT group (3.5 times vs. 2.3 times the upper limit of normal, P = 0.0259). Significant differences in GGT levels persisted 1-month post-procedure (P = 0.0473). Jaundice clearance was significantly higher in the high GTT group (P = 0.0171) after 6 months. Multivariate logistic regression indicated a substantially higher mortality rate in the GGT inadequate group (P = 0.0452), with no significant age difference at operation (P = 0.8449). Preoperative GGT is a valuable predictor for NBA prognosis (area under the curve (AUC) 0.754, 95% confidence interval CI [0.640–0.847], P = 0.001, specificity 91.1%, and sensitivity 61.1%).

Conclusions
High preoperative GGT levels predict better prognosis in patients with NBA undergoing Kasai operation.

Fungal and bacterial infections pose a major global public health challenge due to rising antimicrobial resistance. Over 50% of hospital infections now involve pathogens resistant to multiple drugs, contributing to higher death rates, longer patient illness, and increased/prolonged hospital stays. Exploration of medicinal plants' phytochemical properties provides one avenue for developing new treatment options outside the traditional drug development process to address the intensifying antimicrobial resistance crisis. The plant materials were subjected to cold maceration followed by liquid-liquid partitioning using hexane, dichloromethane (DCM), and ethyl acetate in order of increasing polarity. The derived methanol extracts were screened for phytochemicals using standard procedures. The disk diffusion method evaluated the antimicrobial activity of 50mg/mL of W. ugadensis, P. africana, and A. gummifera against S. aureus, E. coli, and C. albicans. The study qualitatively and quantitatively assessed antibacterial and antifungal activities by observing inhibition zones and determining minimum inhibitory concentration (MIC) values. Several bioactive compounds were detected in the methanolic extract of these plants such as saponins, alkaloids, terpenoids, tannins, flavonoids, phenols, and glycosides. Preliminary disk diffusion screening revealed that W. ugadensis DCM extract exhibited the strongest antimicrobial activity against C. albicans, E. coli, and S. aureus, with mean inhibition zones of 21.0, 10.3, and 15.7mm respectively. MIC analyses with 96-well microliter plate assays confirmed S. aureus as the most susceptible and E. coli as the least vulnerable to the extracts. Tukey’s Multiple Comparison Test (P < 0.05) demonstrated significant differences in antimicrobial activity among A. gummifera, W. ugandensis, and P. africana. The inhibition of the various plant extracts against the tested microorganisms indicates that further study could reveal their potential use in treating infections caused by these microorganisms. Additional research is required to fully elucidate their therapeutic potential and explore practical applications for combating microbial infections.

Published: January 2025

AbstractThe development of practical sodium (Na) metal batteries is hindered by key challenges including dendrite growth, dead metal formation, and unstable solid electrolyte interphase (SEI) growth. A fundamental understanding of the chemo‐mechanical interactions at the Na/SEI interface is critical for designing stable Na metal electrodes. In this work, the coupled electrochemical‐mechanical processes governing the morphological evolution and stability of Na metal during plating and stripping are investigated. The heterogeneous nature of transport and morphological interactions at the Na/SEI interface is revealed to result in nonuniform mechanical overpotentials and reaction fronts, eventually leading to Na filaments or pits. The spatio‐temporal evolution of stress heterogeneities during Na plating and stripping is shown to be asymmetric, manifesting in varying morphological nonuniformities and instability modes. The crucial role of external pressure in modulating the electrochemical‐transport interactions, the mechanical response of Na, and the localized reaction currents and stresses at the Na/SEI interface is demonstrated. At different external pressure conditions, the correlation between transport heterogeneities in the SEI and the onset and propagation of interface instability has been delineated. This work highlights the need for synergistic tailoring of external pressure and SEI heterogeneity toward achieving stable electrodeposition and dissolution in Na metal electrodes.

AbstractGiven the promising application prospects of underwater X‐ray detection technology, traditional perovskite materials, despite their outstanding performance in X‐ray detection, are significantly constrained by their inherent susceptibility to hydrolysis, hindering their effective utilization in underwater environments. To date, most efforts are devoted to evaluating these materials' performance under atmospheric conditions, with a limited exploration into their adaptability in underwater settings. In this study, the successful fabrication of thick perovskite single‐crystal arrays with a thickness of 400 µm and their integration into a stable underwater X‐ray detector array is demonstrated. The single‐crystal arrays exhibit remarkable uniformity in both alignment and dimensions, thereby contributing to improved detection homogeneity and enhanced underwater imaging capabilities. The detector arrays exhibit exceptional X‐ray detection performance, characterized by a high sensitivity of 155,020 µC·Gy−1·cm−2 at 5 V bias and a low detection limit of 52 nGy·s−1, which represents a significant advancement in the frontier of perovskite‐based materials for underwater X‐ray detection. After continuous submersion in water for over 60 days, the detector array maintains its initial X‐ray detection performance, proving its stable adaptability to the underwater environment.

AbstractUltralow‐concentration ether electrolytes hold great promise for cost‐effective sodium‐ion batteries (SIBs), while their inferior cycle stability under high voltages remains an awkward challenge. Herein, ultralow‐concentration diglyme (G2)‐based electrolytes with single sodium salt are found to manifest high‐rate capability when employed for high‐voltage Na3(VOPO4)2F (NVOPF) cathode, but their specific capacity rapidly depletes to exhaustion during long‐term cycling. To address this issue, trace NaBF4 (0.03 m) as electrolyte additive is introduced, which minimally affects ion conductivity of the pristine electrolyte, yet weakens the coordination between Na+ ions and G2 molecules. This allows more PF6− to enter the solvation sheath of Na+ ions, forming a more stable cathode electrolyte interphase and enhancing the cycle performance without sacrificing high‐rate performance (up to 20 C). As a result, the trace NaBF4 modulated G2‐based electrolyte enables the NVOPF cathode to cycle steadily, with a capacity retention of 94.2% over 1000 cycles at a low rate of 1 C. This work provides valuable insights into the modulation of ultralow‐concentration ether electrolytes for use in durable high‐voltage SIBs.

Published: January 2025

AbstractMiniature piezoelectric robots can perform various tasks in narrow spaces, due to their small sizes and agile motions. However, there is key challenge of reconciling large load capacity with agile motions, which limits the integration of functional units. In this work, a miniature agile quadruped piezoelectric robot (AQPR) inspired by hard‐shell animals is proposed. The prominent feature of AQPR is the rigid ring structure, which can be utilized to achieve large load capacity with its high stiffness; the degeneracy of different vibration modes is used to generate multi‐dimensional trajectories at the foot, which can achieve linear and rotational motions. A prototype with size of 30 × 30 × 14.3 mm3 and weight of 6.9 g is produced. The experimental results show that the maximum linear and rotational speed is 255 mm s−1 and 1265°s−1, respectively. The load capacities reach 200 g (≈30 times self‐weight). By using an impulse signal, the resolutions of linear and rotational motions reach 0.25 µm and 32.7 µrad, respectively. Benefiting from small size, large load capacity, high resolution, agile, and fast speed, AQPR shows great potential for applying micro‐operations in narrow spaces, such as large‐scale wafer transport and detection.

AbstractHead and neck squamous cell carcinoma (HNSCC) are invasive solid tumors accounting for high mortality. To improve the clinical outcome, a better understanding of the tumor and its microenvironment (TME) is crucial. Three ‐dimensional (3D) bioprinting is emerging as a powerful tool for recreating the TME in vitro. To establish long‐term HNSCC bioprinted constructs for personalized drug‐testing, this proof‐of‐principle study aims to compare two different innovative tunicate‐derived nanocellulose (NC) hydrogels against the widely used semi‐synthetic gelatin methacryloyl (GelMA). Cell lines of different tumor origin sites are printed in TEMPO and Carboxy‐NC, and GelMA in alginate (GelMAA). Both NC hydrogels show higher bioprintability than GelMAA. Carboxy‐NC supported long‐term HNSCC survival, proliferation, and maintenance of epithelial phenotype in 3D bioprinted constructs similar to GelMAA. The hydrogel microstructure revealed differences in pore size. Importantly, the established HNSCC bioprinted model allowed the testing of radiochemotherapy (RCT) both in cell lines and patient‐derived cultures. Compared to a spheroid model, the cytotoxic effects are less, better reflecting the response in patients. The proof‐of‐principle findings indicate that Carboxy‐NC is a viable alternative to gelatin‐based bioink with improved bioprintability allowing personalized drug‐testing. By adding other cell‐types of the TME, this model can be advanced to a heterotypic one.

AbstractThe evolution of display technologies is rapidly transitioning from traditional screens to advanced augmented reality (AR)/virtual reality (VR) and wearable devices, where quantum dots (QDs) serve as crucial pure‐color emitters. While solution processing efficiently forms QD solids, challenges emerge in subsequent stages, such as layer deposition, etching, and solvent immersion. These issues become especially pronounced when developing diverse form factors, necessitating innovative patterning methods that are both reversible and sustainable. Herein, a novel approach utilizing lipoic acid (LA) as a ligand is presented, featuring a carboxylic acid group for QD surface attachment and a reversible disulfide ring structure. Upon i‐line UV exposure, the LA ligand initiates ring‐opening polymerization (ROP), crosslinking the QDs and enhances their solvent resistance. This method enables precise full‐color QD patterns with feature sizes as small as 3 µm and pixel densities exceeding 3788 ppi. Additionally, it supports the fabrication of stretchable QD composites using LA‐derived monomers. The reversible ROP process allows for flexibility, self‐healing, and QD recovery, promoting sustainability and expanding QD applications for ultra‐fine patterning and on‐silicon displays.

AbstractSingle‐electron transfer, low alkali metal contents, and large‐molecular masses limit the capacity of cathodes. This study uses a cost‐effective and light‐molecular‐mass orthosilicate material, K2FeSiO4, with a high initial potassium content, as a cathode for potassium‐ion batteries to enable the transfer of more than one electron. Despite the limited valence change of Fe ions during cycling, K2FeSiO4 can undergo multiple electron transfers via successive oxygen anionic redox reactions to generate a high reversible capacity. Although the formation of O‒O dimers in K2FeSiO4 occur upon removing large amounts of potassium, the strong binding effect of Si on O mitigates irreversible oxygen release and voltage degradation during cycling. K2FeSiO4 achieves 236 mAh g−1 at 50 mA g−1, with an energy density of 520 Wh kg−1, which can be comparable with commercial LiFePO4 materials. Moreover, it also exhibits 1400 stable cycles under high‐current conditions. These findings enhance the potential commercialization prospects for potassium‐ion batteries.
