A hundred years of Pacific halibut management in the context of global events and trends in fisheries management
Authors: Hutniczak Barbara , Wilson David T. , Stewart Ian J. , Hicks Allan C. 
Published: December 2024

The Convention for the Preservation of the Halibut Fisheries of the Northern Pacific Ocean, signed between Canada and the United States of America on 2 March 1923 and ratified on 21 October 1924, established the International Fisheries Commission, renamed in 1953 to the International Pacific Halibut Commission (IPHC). It was the first international agreement for joint management of a marine fishery resource and a major milestone for development of modern standards for marine conservation. The IPHC’s centennial year is an opportunity to celebrate a remarkable history of the Commission, but also reflect on challenges that shaped its mission. Born from alarms about overfishing during World War I, the Commission gradually gained authority to implement a wide range of conservation measures through established public confidence in its basis for decisions. This paper explores the evolution of management measures applied to Pacific halibut commercial fishing shaped not only by the changing stock conditions and growing demand for seafood, but also global events and trends in fisheries management. It examines the impact of rapid commercialization of fisheries driven by population growth and technological improvements, establishment of exclusive economic zones and altered access to fishing grounds, and adoption of Agenda 21, which highlighted the importance of balancing environmental, economic, and social aspects in fisheries management. It concludes by discussing the lessons learned over the past century and their implications for future fisheries management, emphasizing the importance of international cooperation, adaptive strategies, and science-based policies in sustaining transboundary fish stocks like the Pacific halibut.

Published: December 2024

Objectives and methodsThis study aimed to investigate whether a four-month skateboarding workshop can positively affect attention-focusing skills and postural control in terms of static and dynamic balance in addition to symptoms of ADHD in school-aged children (N = 58). Kinematic and kinetic movement analysis, attention-focusing tests as well as symptom questionnaires were employed to measure differences caused by the skateboarding intervention. A weekly skateboarding workshop was conducted with children diagnosed with ADHD which intended to encourage children to autonomously engage in physical activity. Group differences were analyzed using a generalized linear mixed model. A partial correlation was used to investigate possible relationships between the variables.ResultsA preceding analysis confirmed that children with ADHD perform statistically significantly inferior in the employed tests of balance and concentration ability than unaffected peers of the same age. The main analysis showed that after the skateboarding intervention, children with ADHD were able to improve cognitive and motor test performances as well as symptom expression significantly. Significant improvements were likewise found in the waitlist control group, these were however less pronounced compared to those of the skateboarding intervention group. The correlation analysis revealed that there is no reciprocal influence between cognitive and motor skills, nor between motor skills and ADHD symptomatology in the present patient group. Possible explanations are discussed.ConclusionSkateboarding as a form of movement intervention can be considered an effective method for children with ADHD to deal with their symptoms and deficits. An intervention period of four months has helped children with ADHD discover and embrace an informal sport like skateboarding, thereby finding enjoyment in movement and practice a skill from intrinsic motivation. To retain the benefits, it is advisable to practice a sport on a long-term basis. Thorough conceptualizations to implement this type of therapy await further research.
Rural residents’ willingness to utilize primary care and its influencing factors in the context of graded diagnosis and treatment: a study in Deqing, China
Authors: Gao Meng , Zhu Xueqing 
Published: December 2024

BackgroundGraded diagnosis and treatment is a key component in advancing healthcare system reforms and establishing a foundational healthcare framework. Primary care serves as the cornerstone of this system. Understanding the willingness to seek primary care and the factors influencing it can enhance primary care utilization and address the challenges of “difficult access to healthcare” and “high medical costs.”MethodsThis study, based on data from 415 rural residents in Deqing County, Zhejiang Province, analyzes their willingness to seek primary care and the factors influencing it using the Theory of Planned Behavior and structural equation modeling.ResultsThe results of the study show the following: ① Attitude toward behavioral, subjective norm, and perceived behavior control significantly affect willingness to seek primary care, with attitude toward behavior having the greatest influence. ② Regarding attitude toward behavior, residents’ evaluation of treatment costs in primary care, the medical environment, and trust in doctors significantly impact their willingness to seek primary care. ③ In terms of subjective norms, the level of support from others, as well as the recognition of graded diagnosis and treatment systems and family doctor contracting services, positively influence the willingness to use primary care. ④ For perceived behavioral control, residents’ perception of personal and environmental factors affects their willingness to make a first visit to primary care facilities.ConclusionThe study recommends strengthening the awareness of the necessity of primary care among rural residents, improving the experience at the primary level, stimulating the desire for primary care, and increasing the frequency of primary care utilization.

Published: December 2024

BackgroundProbiotics, which are beneficial to the host, have been shown to benefit the health of cats. Lactic acid bacteria (LAB) are commonly used probiotics, but most strains used for cats are not derived from cats, leading to reduced efficacy and poor adaptation to cats. The objective was to identify LAB with promising probiotic potential specific to cats.MethodLABs were isolated from fecal samples of 20 healthy cats. Gram staining and the survival rate in the simulated gastrointestinal tract were used for preliminary screening. Candidate strains were identified by 16S rDNA sequencing, and further evaluated for adhesion ability, growth characteristics, antibacterial activity, antioxidant capacity, and safety.Results24 Gram-positive isolates were identified, with 10 (F1-F10) showing robust viability in the simulated gastroenteric fluid. These 10 strains exhibited excellent adhesion to Caco-2 cells and strong auto-agglutination properties. They also possessed the capacity to antagonize and aggregate pathogens (Staphylococcus aureus ATCC 25923, Salmonella Braenderup H9812, Escherichia coli ATCC 25922, and Pseudomonas aeruginosa PAO1), Moreover, all strains demonstrated tolerance to H2O2 concentrations ranging from 0.5–2 mmol/L and the ability to scavenge 1, 1-diphenyl-2-picrylhydrazyl (DPPH) free radicals, indicating a certain level of antioxidant activity. Safety tests showed no hemolytic activity, and all but F6 were highly sensitive to antibiotics, with over 62.5% sensitivity to 16 antibiotics. Remarkably, F4 (Lactobacillus reuteri) and F10 (Lactobacillus brevis) exhibited exceptional viability in the simulated gastrointestinal tract, coupled with robust growth potential, enhanced adhesion efficiency, significant antibacterial and antioxidant properties.ConclusionOur findings revealed that F4 (Lactobacillus reuteri) and F10 (Lactobacillus brevis) hold promising potential as probiotics. This research lays a solid scientific foundation for the selection and application of probiotics tailored specifically for cats.
A Distributed and Parallel (k, n) QSS Scheme with Verification Capability
Authors: Andronikos Theodore 
Published: December 2024

This paper presents a new quantum secret sharing scheme featuring a (k, n) threshold and built-in verification. This innovative protocol takes advantage of entanglement and unfolds in three distinct phases. In anticipation of the coming of the distributed quantum computing era, this protocol is designed to function entirely in parallel within a fully distributed environment, where the spymaster and her agents are located in different places. This is a significant shift from most similar protocols that assume that all information recipients are in one location. The spymaster can send all necessary information to her agents at once, streamlining the process. Each phase runs simultaneously, which helps to reduce the overall execution cost. Given its complexity, we offer a thorough analysis to ensure its information-theoretic security, protecting against both external eavesdroppers and internal rogue agents. The protocol does away with the need for quantum signatures or pre-shared keys, making it simpler and less complex. Lastly, its potential for implementation on current quantum computers looks promising since it relies only on CNOT and Hadamard gates, with all participants using similar or identical quantum circuits.

Introdução: A doença inflamatória intestinal, representada principalmente pela doença de Crohn e colite ulcerativa, se manifesta de forma mais agressiva e extensa quando se inicia na infância ou adolescência. Nos últimos anos, houve aumento da sua incidência na população pediátrica. Cerca de 25% dos pacientes desenvolvem essa doença na infância ou adolescência, no entanto, o diagnóstico nessa faixa etária ocorre em 15 a 20% do total de pacientes. Objetivo: Analisar o perfil epidemiológico do número de internações por Doença de Crohn e colite ulcerativa de crianças e adolescentes nas regiões do Brasil. Método: Trata-se de um estudo epidemiológico, ecológico e descritivo, com dados do Departamento de Informática do Sistema Único de Saúde (DATASUS), na categoria de morbidade hospitalar do SUS pelo CID-10. A amostra foi composta por pacientes de 0 a 19 anos internados por doença de Crohn e colite ulcerativa entre 2013 e 2023. Utilizou-se as variáveis: ano de atendimento, região brasileira, unidade da federação, cor/raça, faixa etária, sexo, média de permanência, custos médios de internação e óbitos. Os dados foram calculados e analisados por meio do software Microsoft Office Excel. Resultados: As internações hospitalares por Doença de Crohn e Colite Ulcerativa totalizaram 10.816 entre 2013 e 2023, com maior concentração na região Nordeste, que registrou 3.775 internações (34,9%), seguida pela região Sudeste com 3.384 internações (31,29%). A média de permanência hospitalar variou entre 4,5 e 6,7 dias. Durante o período analisado, ocorreram 53 óbitos, sendo a maioria na região Sudeste (37,7%). A maioria dos pacientes se identificou como branca (35,7%) ou parda (30,4%). O custo médio por internação em 2023 foi de R$657,82, com a maior concentração de gastos na região Sudeste (42,97% do total). Discussão: A concentração de hospitalizações nas regiões Sudeste e Nordeste têm associação direta ao desenvolvimento econômico nos últimos 10 anos. Nota-se disparidades regionais relacionadas ao valor médio de internações que reflete desigualdades no sistema de saúde. Além disso, a média de permanência hospitalar sugere o nível de gravidade da doença, assim como o número de óbitos evidencia sua baixa letalidade em pacientes pediátricos no Brasil. Na maioria dos casos, os pacientes são brancos demonstrando acesso desigual à saúde. Conclusão: Evidencia-se disparidades em relação à distribuição do número de internações entre as regiões do Brasil, que podem estar associadas a fatores predisponentes já discutidos. A produção de dados epidemiológicos auxilia na identificação das localidades que necessitam de políticas públicas direcionadas para prevenção de complicações, diagnóstico precoce e tratamento eficaz.

Os hormônios tireoidianos, tiroxina e triiodotironina, atuam regulando o metabolismo basal do indivíduo. É comum entre atletas o uso abusivo de hormônios tireoidianos para promoção de hipertrofia muscular, visando um melhor desempenho na prática de exercício físico e melhora da aparência corporal. Este estudo tem por objetivo avaliar o uso abusivo de hormônios tireoidianos por praticantes de exercícios físicos, bem como o impacto cardiovascular, metabólico e ósseo, além da taxa de mortalidade associada a esse uso. Foi conduzida uma revisão narrativa de literatura. A busca teve foco em artigos com maior grau de evidência, como revisões sistemáticas e metanálises. Além disso, foram utilizados livros e diretrizes de sociedades médicas brasileiras que tratam do tema. Priorizou-se a utilização de literatura publicada entre 2000 e 2023. São encontrados diversos relatos de consequências graves ligadas ao uso indevido desses hormônios, principalmente casos de fibrilação ventricular causando morte súbita, além de taquicardia, fibrilação atrial e outras arritmias. Também foi observado diminuição da densidade mineral óssea, ocasionando um risco maior para osteoporose e fraturas, supressão da função tireoidiana normal, episódios de amenorreia e disfunção sexual, aumento significativo no risco de complicações graves, incluindo a tempestade tireoidiana e a morte súbita por causa cardiovascular. É notável o impacto negativo do uso abusivo de hormônios tireoidianos, no entanto, necessita-se de estudos com uma meta-análise quantitativa para melhores conclusões.

Published: December 2024

With the advent and subsequent explosion of the internet, global connectivity has been achieved, and is on the rise. This provides a host of advantages such as connectivity and communication, information broadcast and transmission, amongst others. This however introduces a new set of challenges: the safety and protection of these communication channels amongst them. Information has always been power, and the widespread mature of information only results in the widespread attempts to procure it, sometimes via illegal channels. In view of this, this research aims at detecting Crypto-ransomware and locker ransomware. Data was collected from an open repository and cleaned. The cleaned data was then split into tests, train sets and validation which was used to train a number of ML models based on the: Random Forest algorithm, Support Vector Machine (SVM) and Gradient boosting algorithm. Ransomware is one of the well-known ways and frequent use which cyber-attackers use in infecting their victims, either through phishing or drive download. Attackers will create an email pretending to be from a genuine resource and send it to their targeted victims. However, this research illustrated how to combat crypto-ransomware and locker ransomware. Implementing the machine learning algorithm, the system can detect ransomware under 30’s, giving computer users over 90% assurance of their system for ransomware free.
