PurposeBased on life course theories, health among older people is driven by a continuous and cumulative process that develops over the life course. To better understand the aging process, it is important to assess associations between parity and heart disease in older people of China.MethodThe associations between heart disease prevalence and number of births, number of boys or girls ever born were evaluated among 5,990 samples (mean age 64.1 years) using the Probit regression model based on the data from China Health and Retirement Longitudinal Study (CHARLS) conducted in 2013 and 2018. The model was adjusted only for rural or urban residents, and multivariate regression models were run separately by gender.ResultsOur results showed that more than three children or more than two boys ever born were associated with a higher risk of heart disease. However, the number of girls ever born had no significant effect on heart disease in the elderly. We further analyzed the group difference between urban and rural residents using the regression model. More than three children or more than two boys ever born were associated with a high risk of heart disease in rural areas. Compared to urban residents, rural residents were more likely to be suffering from heart disease due to high parity. When considering the digender difference the paper found that more than three children ever born were associated with a high risk of heart disease in the female group. Late age at the time of giving birth for the first time was associated with a poorer risk level of heart disease in the rural residents, because the phenomenon of early childbearing was serious in the rural residents. But after considering the impact on the physical health of using chronic diseases, the first birth and the last birth both increased the risk of heart disease.ConclusionsSome policy implications were being put forward. Firstly, parents who were ready to give birth should be aware of the possible health loss of high parity. Postpartum nutrition supplements and chronic disease prevention were suggested to prevent heart disease in later life. Secondly, the elderly in rural areas should pay more attention to heart diseases. Participating in more daily exercise and physical examinations was a good choice to reduce the risk of heart disease. Thirdly, women who give birth prematurely have a higher risk of CVD. Based on our results, age at entry to parenthood was closely related to the risk of heart disease in later life.

BackgroundThe COVID-19 pandemic has a serious impact on the mental health of the public due to its economic and social impact. And psychological effects have led to drug and alcohol abuse. After the city lifted the lockdown, we consecutively encountered several young nitrous oxide abusers admitted to hospital for neurological treatment.PurposeTo inform physician decisions and social intervention, this observational study aimed at investigating the neurological and psychological characteristics of nitrous oxide abusers and its underlying causes during the COVID-19 lockdown.MethodsThe nitrous oxide abusers who sought neurological treatment at our hospital between May 2020 and June 2020 were enrolled. Clinical data including socio-demographic, physical examination, laboratory examination, electromyography and neuroimaging were collected. Their motivations for inhaling nitrous oxide, knowledge about the nitrous oxide abuse and the accompanying of family were investigated face to face. Psychological status was assessed by the Symptom Checklist 90 (SCL-90) psychological evaluation.ResultsSix nitrous oxide abusers were enrolled and the age was 22 ± 4.3. Clinical presentations included varying degrees of limb numbness and an ataxic gait. Laboratory examination revealed that all the patients did not have pernicious anemia, 4 patients had decreased vitamin B12 while 3 patients exhibited elevated homocysteine levels. MR of the spinal cord revealed that 4 patients had abnormal signals in the cervical spinal cord of high symmetry with splayed or inverted V sign after T2WI. Electromyogram (EMG) test showed 5 patients had peripheral nerve damage. The SCL-90 psychological evaluation results indicated that all patients had severe anxiety, depression and psychosis and they had severer psychological problems than ordinary citizens. Their motives for inhaling nitrous oxide are to relieve boredom, curiosity and buddy pressure. Their family spent &lt;1 day per week to stay with them during city lockdown.ConclusionThe enrolled patients caused by abuse of nitrous oxide presented with symptoms of subacute combined with spinal degeneration. They had more serious psychological problems related to the COVID-19 pandemic. These cases make us value the psychological problems of young people under the outbreak and take multi-layered measures from families, schools (companies), hospitals, and governments to address it.

Published: June 2022

BackgroundWhile wheelchair basketball is one of the most popular Paralympic sports, it eventually causes shoulder problems and pain in many athletes. However, shoulder kinetics has never been assessed during propulsion in wheelchair basketball. This study analyzes the impact of sprinting and dribbling on pushrim and shoulder kinetics in terms of external forces and net muscular moments.MethodsA group of 10 experienced wheelchair basketball athletes with various classifications performed four, 9-m sprints on a basketball court using classic synchronous propulsion, and four sprints while dribbling forward. Pushrim and shoulder kinetics were calculated by inverse dynamics, using a motion capture device and instrumented wheels.FindingsSprinting was associated to peak shoulder load from 13 to 346% higher than in previous studies on standard wheelchair propulsion in most force/moment components. Compared to sprinting without a ball, dribbling reduced the speed, the peak external forces in the anterior and medial direction at the shoulder, and the peak net shoulder moment of internal rotation.InterpretationThe high shoulder load calculated during both sprinting and dribbling should be considered during training sessions to avoid overloading the shoulder. Dribbling generally reduced the shoulder load, which suggests that propelling while dribbling does not put the shoulder at more risk of musculoskeletal disorders than sprinting.

El método para resolver problemas de Estimación de Estado utilizando filtros extendidos de Kalman en sistemas eléctricos de potencia se presenta en este trabajo. Los estimadores trabajan con información en tiempo real de diferentes dispositivos de medida instalados en el sistema y forman una base de datos que se concentra en el centro de control a través de SCADA, esta información funciona como filtros ante datos incorrectos. La técnica de mínimos cuadrados ponderados (WLS) se utiliza comúnmente para resolver el problema de estimación debido a sus propiedades estadísticas. Sin embargo, otras técnicas de estimación de estado dinámico se estructuran con diversas variaciones del filtro de Kalman. El Filtro de Kalman Extendido (EKF), como algoritmo para los sistemas no lineales de estado de estimación, es eficiente. La complejidad de la implementación, la precisión y la eficiencia del cálculo, la resistencia a los errores de medición y la sensibilidad a las escalas del sistema se analizan en un sistema estándar IEEE de 14 barras.

Justificativa: A ergonomia relaciona o ser humano com o trabalho objetivando garantir uma melhor qualidade de vida em geral. Na perspectiva dos massoterapeutas, há naturalmente uma exposição a posturas desgastantes em tempo excessivo, podendo desenvolver as chamadas LERs e DORTs, que geram impactos negativos para o trabalhador e sua função. Em conjunto, a deficiência visual pode se tornar mais um obstáculo para uma melhor qualidade de vida, pela fadiga, estresse e menos oportunidades. Objetivo: Analisar o risco ergonômico e a qualidade de vida em massoterapeutas cegos. Métodos: O estudo foi de caráter observacional, de corte transversal descritivo e quantitativo, com 5 massoterapeutas, de ambos os sexos, com idade entre 18 e 59 anos. Cada participante respondeu a 5 questionários: sociodemográfico, censo de ergonomia, WHOQOL e os check-lists de avaliação da exigência da coluna vertebral e para avaliação das condições biomecânicas do trabalho. Resultados: 80% dos entrevistados apresentam dor na coluna e membros superiores, apenas 40% destes alegam ter relação com o trabalho e 60% possuem um incômodo leve. Através do RULA, foi visto que em 60% dos casos se faz necessário introduzir mudanças imediatas no local de trabalho; em 40% dos indivíduos o posto de trabalho apresentou altíssima exigência e 100%, por itens de desqualificação, apresentam uma condição ergonômica ruim. Conclusão: Os massoterapeutas estão sujeitos a lesões pelas exigências da profissão, sugere-se então a implantação da fisioterapia preventiva para diminuir esse risco e mais pesquisas sobre essa população.

Introdução: A osteoartrite (OA) é um distúrbio articular bastante comum em nossa sociedade e sua incidência aumenta com o avançar da idade. Embora possa afetar várias articulações do nosso corpo, as alterações mais evidentes são observadas em grandes articulações de carga. A abordagem terapêutica da OA visa reduzir a sintomatologia dolorosa, diminuir os níveis de rigidez, melhorar a mobilidade e a qualidade de vida. Dentre as opções terapêuticas não farmacológicas temos a terapia com ultrassom (US) que promove um aquecimento profundo nos tecidos e cujo tópico carece de mais evidências científicas que comprovem sua eficácia no alívio da dor em pacientes com OA de joelho. Objetivo: Este trabalho visa descrever os efeitos e a eficácia do ultrassom terapeêutico (UST) no tratamento da dor e função na osteoartrose primária de joelhos. Métodos: Foi realizado uma busca sistemática nas bases de dados PubMed, LILACS, CENTRAL, SCIELO e PEDro por ensaios clínicos randomizados e quasi-randomizados, publicados nos últimos 10 anos. As palavras-chave utilizadas foram Ultrassom, Terapia por Ultrassom, Dor, Joelho, Articulação do Joelho, Osteoartrite do Joelho. Resultados: Seis estudos, que avaliaram ao todo 561 paciente foram selecionados. Alguns estudos demonstraram que não houve diferença significativa entre os grupos US contínuo e US pulsado no alívio da dor e melhora da função. O US quando usado como coadjuvante terapêutico resultou em melhora da dor. Conclusão: Os trabalhos selecionados sugerem que aplicações de US combinado principalmente com exercícios são eficazes no alivio de dor e melhora da funcionalidade de pacientes com osteoartrite de joelho.

Sesuai dengan program kerja yang akan kami abdikan, kelurahan Bereng Bengkel secara geografis memiliki area yang dilewati oleh aliran sungai Kahayan, sehingga hal ini tentunya menjadi potensi pengembangan perekonomian bagi masyarakat Kelurahan Bereng Bengkel terutama menjadi solusi bagi masyarakat daerah aliran sungai (DAS) agar dapat memulihkan dan meningkatkan perekonomian yang juga jatuh akibat terdampak Pandemi Covid-19. Pengabdian yang akan kami lakukan di Kelurahan Bereng Bengkel adalah pemanfaatan sumber daya alam kelurahan Bereng Bengkel yakni cukup melimpahnya air yang dapat dipergunakan untuk budidaya ikan lokal khas Kalimantan misalnya ikan Patin dan ikan Baung. Potensi lokal inilah yang menjadi daya tarik bagi kami tim Pengabdian Kepada Masyarakat FKIP Universitas Palangka Raya untuk meningkatkan ekonomi masyarakat melalui pengelolaan usaha berbasis potensi sumber daya lokal. Namun permasalahan yang terjadi adalah tidak semua masyarakat menganggap budidaya ikan menguntungkan sehingga banyak masyarakat yang belum sadar akan potensi ekonomi yang dimiliki daerahnya sendiri. Hal ini disebabkan juga karena masyarakat memiliki keterbatasan pengetahuan dan keterampilan dalam mengolah potensi alam khususnya dalam bidang budidaya ikan lokal. Apabila masyarakat memiliki pengetahuan dan keterampilan yang memadai tentang budidaya ikan lokal tentunya hal tersebut akan mampu meningkatkan kesejahteraan masyarakat Kelurahan Bereng Bengkel. Tujuan dan manfaat yang ingin kami capai melalui pengabdian ini adalah untuk membentuk individu masyarakat menjadi lebih mandiri, membantu masyarakat lebih memahami pembudidayaan ikan lokal dan membantu masyarakat menciptakan pendapatan ekonomi yang lebih baik dari sebelumnya.

Frustrated lattice orientation of cholesteric blue phase II induced by micro-patterned surface alignment
Authors: Nakajima Kazuma , Tsukamoto Yuji , Mitsuhashi Shogo , Ozaki Masanori 
Published: June 2022

Abstract
We investigated the lattice orientation behavior of cholesteric blue phase II on a stripe-patterned surface, on which the orientational easy axis of the adjacent region changes discontinuously. The lattice orientation depends on the patterned-region size when the easy axes of the adjacent patterns are orthogonal to each other. For the large regional period, the (110) lattice planes are parallel to the substrates, and the [001] axes within each region are aligned along the corresponding easy axes, whereas for a small period, owing to the orientational frustration caused by the elastic strain, the (100) planes are uniform regardless of the pattern.

Abstract
Based on interconnected ion sputtering and cathodoluminescence spectroscopy, an optical spectroscopic strategy has been developed to profile depth-dependent polarization effects in an AlGaN multiple-quantum-well structure. Two emission bands at about 258 nm and 315 nm have been identified to originate from the quantum wells and Ga-rich domains, respectively, and their depth-dependent spectral characteristics reveal that the spontaneous polarization dominates the piezoelectric polarization in the quantum wells, and the emission wavelengths vary with respect to the etching depth due to interactions of the spontaneous polarization field with the piezoelectric polarization field and the surface charge induced electric field.

Published: June 2022

Abstract
Flower-like ZnO/SnS2 heterojunction was constructed as photocatalyst. The heterojunction shows hierarchical architecture structure, in which SnS2 nanosheets are uniformly decorated by ZnO nanoclusters. Compared to SnS2, the ZnO/SnS2 heterojunction displays improved photocatalytic efficiency for degradation of organic dye MB and hydrogen evolution. ZnO/SnS2 heterojunction reveals an optimal hydrogen production rate of 346.1 μmol h−1 g−1, about 2.7 times higher than SnS2. The boosting photocatalytic performance is ascribed to the special hierarchical structure and synergetic effect of ZnO/SnS2 heterojunction, which can enhance the specific surface area and promote the separation of photogenerated electron–hole pairs.
