Research Progress on Changes of Lower Limb Stiffness in Older Adults During Ageing / 医用生物力学

Walking downstairs and running are common actions in daily life;however,older adults with functional decline are prone to falls or injuries.To cope with various situations and avoid falls,the first neuroprotective motor mechanism activated by the body is the regulation of lower limb stiffness.Hence,this study retrieved and collected relevant research results from databases such as China Knowledge,Wanfang,Google Scholar,and Web of Science,using key words such as elderly and lower limb stiffness,and summarized the similarities and differences in changes in lower limb stiffness in different action tasks.The findings show that interventions on controllable factors can improve changes in lower limb stiffness to prevent falls in older adults.However,owing to the small number of related studies,it is necessary to further investigate the effects of action interventions on lower limb stiffness in older adults to obtain reliable regularity features and references.

Effects of long-term physical exercise on young people's balance ability under different cognitive tasks / 中国康复医学杂志

Objective:To explore the balance performance of young adults under the interference of different cognitive tasks,and the moderating effect of long-term physical exercise. Method:The static and dynamic balance of healthy young people with physical exercise habit and without physical exercise habit were tested under the interference of different cognitive tasks.One-way repeated mea-sures ANOVA was performed with the group variable(Group)as the between-subjects factor and the results of multiple balance tests(Task)as the within-subjects variable. Result:Long term physical exercise had a positive moderating effect on the static balance during calculation,singing,and writing interference,the static mediolateral symmetrical balance during writing interference,the static anteroposterior symmetrical balance during singing interference,and the dynamic balance during comput-ing interference(P＜0.05).The dual-task cost of young people was significantly reduced when they are dis-turbed by the corresponding cognitive tasks(P＜0.05).However,it had a negative regulatory effect on the stat-ic mediolateral balance of calculation interference,the static anteroposterior balance of reading interference,and the dynamic mediolateral balance of calculation and singing interference(P＜0.05). Conclusion:Long term physical exercise has a significant moderating effect on young people's dynamic and static balance performance when different cognitive tasks are disturbed.

La tarea docente en el proceso de enseñanza aprendizaje de las ciencias básicas biomédicas

Son numerosas las investigaciones que han abordado la tarea docente como un elemento esencial para la adquisición de conocimientos y el desarrollo de habilidades en estudiantes de diferentes niveles de formación y, de manera particular, en el universitario. Con respecto a ella, existen diversos enfoques en dependencia del punto de vista considerado. El presente artículo tuvo como objetivo determinar los referentes necesarios para el diseño de un sistema de tareas docentes de contenidos histológicos para el proceso de enseñanza aprendizaje de las ciencias básicas biomédicas (CBB) en la carrera de medicina. Se identificaron como regularidades esenciales, consideradas por los autores como referentes de valor: el reconocimiento de la tarea docente como un eslabón del proceso de enseñanza aprendizaje y un elemento básico de este, que persigue objetivos determinados y lleva implícita esencialmente la actividad del estudiante; es, por tanto, un recurso didáctico para planificar, organizar, regular y controlar su actividad encaminada a adquirir los conocimientos necesarios sobre la estructura histológica del organismo humano normal, además de entrenar habilidades y fomentar valores vinculados a la profesión para la cual se están formando. A partir de lo anterior se definió un concepto de "tarea docente de CBB" y de "contenidos histológicos".

Very much research has addressed the teaching task as an essential element for knowledge acquisition and the development of skills in students at different levels of education, as well as at the university level in particular. With respect to this topic, there are different approaches, depending on the considered point of view. The aim of this article was to determine the necessary references for designing a system of teaching tasks with contents about histology for the teaching-learning process of basic biomedical sciences in the medical major. The following were identified as essential regularities, considered by the authors to be valuable references: acknowledgment of the teaching task as a link within the teaching-learning process and a basic element of it, which pursues specific objectives and essentially involves the student's activity; it is, therefore, a didactic resource for planning, organizing, regulating and controlling their activity aimed at acquiring the necessary knowledge about the histological structure of the normal human organism, in addition to training skills and promoting values linked to the profession for which they are being trained. Based on the above, a concept was defined for teaching tasks in basic biomedical sciences and contents about histology.

Objective:To explore the relationship between workplace procrastination and illegitimate tasks in-kindergarten teachersand the role of work disengagement and coworker support in their relationship.Methods:A to-tal of 245 kindergarten teachers were selected from 3 cities in Zhejiang Province.They were assessed with the Workplace Procrastination Scale(WPS),Bern Illegitimate Tasks Scale(BITS),Work Disengagement Scale(WDS),Colleague Support Scale(CSS).The models were tested by using Process macro for SPSS,and non-para-metric percentile bootstrap method was used to analyze the mediating effect and moderating effect.Results:There were significant differences in the total scores of workplace procrastination among kindergarten teachers in different marital status,age,teaching age,education level,teaching gradeand kindergarten level(Ps＜0.05).Work disengage-ment played a significant mediating role between workplace procrastination and illegitimate tasks(indirect effect=0.26,95％CI:0.16-0.37).Coworker support played a significant moderating role in the impact of illegitimate tasks on work disengagement(simple slope=0.72,0.39;P＜0.001).Conclusion:It suggests that workplace pro-crastination is related to illegitimate tasksin kindergarten teachers.Work disengagement plays a mediating role in their relationship,and coworker support plays a moderating role in the first half of this mediating role.

Enfermedad pulmonar obstructiva crónica (EPOC): no siempre relacionada con tabaquismo / Chronic Obstructive Pulmonary Disease (COPD): Not Always Related to Smoking

Existen un número importante de riesgos no relacionados al tabaco pasible de provocar la EPOC, por lo que la carga de la EPOC no tabáquica es mucho mayor de lo pensado. En los países del tercer mundo, existen importantes agentes de peligro no relacionados al tabaco pasibles de provocar la EPOC. No está aclarada la patogenia de la EPOC y su relación con la exposición laboral a polvos, gases y humos. Son necesarias más investigaciones experimentales y epidemiológicas de mayor magnitud para confirmar la relación entre estas dos variables. Aproximadamente el 15 % de la EPOC relacionada con el trabajo está agravada por el tabaquismo y continúan publicándose nuevos agentes que causan EPOC. Las mujeres presentan una manifestación clínica diferente de la EPOC y son -ante exposiciones semejantes- más propensas a desarrollar la enfermedad que los hombres. La protección personal de los trabajadores es de importancia, ya que es dificultoso valorar la naturaleza del polvo, humo o gases, su concentración ambiente y el tiempo de exposición.

There are a lot of risks unrelated to tobacco that can cause COPD, so the burden of non-smoking COPD is much greater than previously thought. In the Third World countries, there is a significant number of non-tobacco-related risk agents capable of causing COPD. The pathogenesis of COPD and its relationship with occupational exposure to dust, gases, and fumes is not fully understood. Further experimental and epidemiological research on a larger scale is needed to confirm the relationship between these two variables. Approximately 15 % of COPD is related to work, and aggravated by smoking. New agents causing COPD continue to be reported and published. Women exhibit a different clinical manifestation of COPD and, under similar exposures, are more prone to developing the disease compared to men. Personal protection for workers is of particular importance since it is challenging to as sess the nature of dust, smoke, or gases, their ambient concentration, and the duration of the exposure.

Uso del método de observación: una propuesta de aplicación al análisis de estrategias de resolución de problemas en niños con discapacidad / Use of observational method: a proposal for application to the analysis of problem-solving strategies in children with disabilities

El presente trabajo se ocupa de evaluar posibilidades del método de observación aplicado al análisis de estrategias de resolución de problemas en niños con discapacidad mediante juegos y tareas estructuradas. El marco teórico de referencia de esta contribución está representado por la teoría de la resolución de problemas, que contiene los principales procesos que intervienen en la gestión de los problemas y que nosotros aplicamos al desarrollo cognitivo y metacognitivo atípico. Junto con tres tareas diferentes estructuradas(Torre de Hanoi, Tetris y Bloques de construcción), usamos dos listas de comportamientos para codificar estrategias de resolución de problemas adoptadas por niños y/o adolescentes con desarrollo atípico. La aplicación de este tipo de observación con el uso de listas de comportamientos podría ser útil para crear en relación entre la investigación cualitativa y cuantitativa para mejorar el conocimiento de las estrategias de resolución de problemas y competencias metacognitivas en niños desarrollados atípicos(AU)

This paper is concerned with evaluating the possibilities of the observational method applied to the analysis of problem-solving strategies in children with disabilities through structured tasks. The theoretical framework of reference for this contribution is represented by the theory of problem-solving, containing the main processes involved in problem management,which we apply to atypical cognitive and metacognitive development. Together with three different structured tasks (Tower of Hanoi, Tetris, and Building Blocks), we used two lists of behaviors to code problem-solving strategies adopted by children and/or adolescents with atypical development. The application of this type of observation with the use of lists of behaviors could be useful to create a link between qualitative and quantitative research to improve the knowledge of problem-solving strategies and metacognitive competencies in atypically developed children(AU)

Psychometric properties of the Movement Assessment Battery for Children (MABC-2): an analysis based on the Item Response Theory / A falta capacidade discriminatória em tarefas motoras do Movement Assessment Battery for Children ­ 2: O que a Teoria de Resposta ao Item revela?

Introduction: the American Psychiatric Association reveals that 6% of school-age children have developmental coordination disorder. Objective: this study aimed at assessing the suitability of the tasks proposed by the MABC-2 motor assessment instrument based on the psychometric properties of such an instrument and the analysis of the Item Response Theory. Methods: 582 children ranging in age from 3 to 5 years old of both sexes participated in the study. The motor tasks suitability for children was verified by using the Gradual Response Model, and applying the Maximum Likelihood Estimation method. Results: the motor task 'bicycle trail' showed a lower discriminatory power and was removed from the analysis. Considering the 'Aiming & Catching' dimension, 'Threading Beads' was the motor task with the highest degree of difficulty. Regarding balance, the 'One Leg Balance' task was classified as having a high degree of difficulty; on the other hand, the motor tasks 'Jumping on mats' and 'Catching Beanbag' required below average motor performance levels, that is, they are tasks with low discrimination capacity. The results showed that the low discriminative capacity of some MABC-2 items regarding this study sample makes it difficult to correctly classify the child's general motor performance level.Conclusion: the findings show that there is a need to review the suitability of the MABC-2 motor tasks in order to equate the difficulty and discriminatory capacity of the tasks so that standardization more appropriate to the reality of children from different populations is established.Keywords: psychometric properties, motor tasks, motor performance.

Introdução: a American Psychiatric Association revela que 6% das crianças em idade escolar apresentavam desordem coordenativa desenvolvimental. Objetivo: analisar a adequabilidade das tarefas propostas no instrumento de avaliação motora MABC-2 a partir da análise da teoria de resposta ao item.Método: participaram do estudo 582 crianças de 3 a 5 anos de idade, de ambos os sexos. A adequabilidade das tarefas motoras às crianças foi verificada por meio do modelo de resposta gradual, com método de estimação de máxima verossimilhança. Resultados: os resultados evidenciaram a existência de apenas dois fatores, sendo que as tarefas relativas ao "Equilíbrio" e "Lançar e "Receber", das dimensões propostas no modelo original foi agrupado em uma dimensão. Além disso, a tarefa motora "Caminho da bicicleta" não apresentou bom ajuste ao modelo, sendo eliminada das análises. Com isto, o modelo final apresentou bons índices de ajuste, e os parâmetros relacionados à tarefa indicaram a falta de equivalência de dificuldade e capacidade discriminatória entre as tarefas motoras do instrumento.Conclusão: os achados indicam que existe a necessidade de rever a adequabilidade das tarefas motoras do MABC-2 no sentido de equiparar a dificuldade e a capacidade discriminatória das tarefas a fim de criar uma padronização mais adequada a realidade de crianças de diferentes populações.

RESUMEN: En este trabajo se analizan las habilidades de visualización y la generalización en la resolución por una persona ciega de dos tareas propuestas para la identificación del talento matemático. A partir de este análisis, se establecen algunas pautas para adaptar las tareas y se contrastan con las habilidades requeridas en la prueba original, especialmente en las relativas a las características del talento asociadas a la generalización. Se evidencia que las personas con discapacidad visual requieren la manifestación de otras habilidades, como por ejemplo la memoria visual y la percepción de las relaciones espaciales que no son imprescindibles en el planteamiento original.

RESUMO: Neste trabalho, analisamos as capacidades de visualização e de generalização na resolução por uma pessoa cega de duas tarefas propostas para a identificação de talentos matemáticos. A partir dessa análise, foram estabelecidas algumas diretrizes para a adaptação das tarefas e contrastadas com as competências exigidas no teste original, especialmente as relacionadas às características do talento associadas à generalização. Verificamos que as pessoas com deficiência visual requerem a manifestação de outras capacidades, tais como a memória visual e a percepção de relações espaciais, que não são essenciais na abordagem original.

ABSTRACT: In this work, we analyze the visualization skills and generalization in the resolution by a blind person of two tasks proposed for the identification of mathematical talent. From this analysis, some guidelines were established to adapt the tasks and contrasted with the skills required in the original test, especially those related to the characteristics of talent associated with generalization. We verifed that people with visual impairment require the manifestation of other skills, such as visual memory and perception of spatial relationships, which are not essential in the original statement.

Research on implementation status and key issues of function fulfillment in China national medical centers and national regional medical centers / 中华医院管理杂志

China national medical centers and national regional medical centers are the key entities to expand the availability of quality medical resources and ensure they are better distributed among regions. It is of great significance for the centers′ high-quality development to understand the key issues in the construction and progression of centers by evaluating the performance of their function fulfillment. The evaluation framework of this study was based on the " structure-process-outcome" model. The study was divided into three stages, including centers′ self-evaluation, data reporting, and on-site investigation and evaluation. The team conducted the evaluation on 15 entity hospitals supporting 6 national medical centers and 5 national regional medical centers that had been approved by October 2020. As the results showed, the funding and policy support for these centers from governments at all levels were increased, the internal and external management mechanism of the centers were preliminarily set up, the functions of the centers were executed properly, and the " radiation effect" of the centers was in place gradually. The key problems hindering the fulfillment of functions concern the mechanisms that were not sound and need to be further refined, which included the field of financial investment and policy guarantee for the entity hospitals, internal and external management of centers, introduction and cultivaton of the talented, and the innovation and transformation of scientific achievements which facilitates breakthroughs in core technologies. To promote the efficient implementation of functional tasks of the centers, the authors proposed four suggestions. First, the " commission and province co-construction" mechanism should be further improved to augment investment and policy guarantee from the government. Second, the internal organization and management mechanism of each centers should be optimized. Third, the reform and innovation in the training and management system of the talented medical personnel should be accelerated. Last, the health needs oriented mechanism for scientific research innovation and achievements transformation should be established.

The Role of Mental Imagery in Obsessive-Compulsive Disorder: An Explorative Study

Background: The present study aimed to investigate how mental imagery affects the manifestation of symptoms among people with OCD, considering its impact on symptom severity. Methodology: For the said purpose, we compared people with OCD (n=30) with a clinical control group (people suffering from Schizophrenia; (n=30) and community control group (n=30). Yale Brown Obsessive Compulsive Scale (assess symptom severity of OCD), Spontaneous Use of Imagery Scale (spontaneity of imagery), Vividness of Visual Imagery Questionnaire (vividness of imagery) along with Mental Clock Task (ability to generate images), Change Detection Task (maintenance of imagery), Match to Sample Task (image inspection), Mental Rotation Task (image manipulation-transformation), Ambiguous Figure Task (image restructuring) and Image Combination Task (mental synthesis) were used in the study. Results: The result suggests that there is a difference in terms of the spontaneous use of mental imagery in daily life among the three groups. Regression analysis showed that the Image Generation and Image Manipulation-Transformation capacity plays a role in the manifestation or maintenance of Obsessive and Compulsive symptoms in OCD. Both the factors independently predict the symptom severity of Obsessive Compulsive disorder, but not in Schizophrenia.

Diferencias en la reserva neural en relación al entrenamiento musical / Differences in the neural reserve in relation to music training

La reserva neural es un subcomponente de la reserva cognitiva y refiere a las diferencias en los paradigmas cognitivos que subyacen al desempeño de tareas en un cerebro sano. Puede darse por diferencias innatas (inteligencia, edad) o ambientales, como el entrenamiento musical. Éste está relacionado con diferencias cerebrales y cognitivas. El objetivo del presente estudio es realizar una revisión bibliográfica de investigaciones que evaluaron rendimiento cognitivo en músicos como no músicos, y establecer diferencias en la reserva cognitiva y, más específicamente, el subcomponente de reserva neural, entre ambos grupos. Se parte de la suposición de que los músicos poseen un rendimiento superior en tareas cognitivas con respecto a los no músicos y que esto está relacionado con una mayor reserva neural debido al entrenamiento musical. Los resultados son contradictorios. Se encontraron algunas diferencias en dominios cercanos a la práctica musical en adultos jóvenes, y en diversos dominios en adultos mayores. Las diferencias entre grupos, que no diferían en inteligencia, podrían ser atribuibles a una mayor reserva cognitiva. También hay relaciones con el tipo de instrumento, los años y la edad de comienzo de la práctica musical. Se sugiere replicar los hallazgos controlando diversas variables(AU)

Neural reserve is a subcomponent of cognitive reserve and refers to the differences in cognitive paradigms that underlie task performance in a healthy brain. It can occur due to innate (intelligence, age) or environmental differences, such as musical training. This is related to brain and cognitive differences. The aim of the present study is to carry out a bibliographic review of investigations that evaluated cognitive performance in musicians as well as non-musicians, and to establish differences in cognitive reserve and, more specifically, the neural reserve subcomponent, between both groups. It is assumed that musicians have superior cognitive tasks performance compared to non-musicians and that this is related to a greater neural reserve due to musical training. The results are contradictory. Some differences were found in domains close to musical practice in young adults, and in various domains in older adults. The differences between groups, which did not differ in intelligence, could be attributable to a greater cognitive reserve. There are also relationships with the type of instrument, the years and the age of beginning of the musical practice. It is suggested to replicate the findings controlling for various variables(AU)

Diseño de un instrumento de preferencias vocacionales en Administración, Materiales y Biotecnología / Design of an Instrument for Vocational Preferences in Administration, Materials and Biotechnology

Resumen Este estudio buscó diseñar y evaluar una prueba de preferencias vocacionales para las carreras de Administración de Empresas, Ingeniería en Materiales e Ingeniería en Biotecnología en el Instituto Tecnológico de Costa Rica (ITCR). Para ello, se construyó previamente el perfil vocacional de cada carrera a partir del cual se redactaron los ítems de la prueba. Participaron 480 estudiantes con una media de edad de 22.07 años, 53.19% mujeres y 46.81% hombres. Se obtuvo información del perfil de cada carrera por parte de estudiantes y docentes. Posteriormente, la revisaron grupos de expertos. A partir del perfil definido, se redactaron los ítems de la prueba. Luego, se evaluaron sus características psicométricas con análisis factoriales. Se obtuvieron adecuados indicadores de bondad de ajuste. La prueba vocacional incluyó tres escalas: habilidades, intereses y tareas vocacionales. La escala de habilidades evaluó seis factores: lógico-matemática, física, química, biológica, liderazgo y autorregulación- disciplina. Por su parte, las escalas de tareas e interés se utilizaron para definir las preferencias por los tres factores evaluados: Administración, Materiales y Biotecnología. Finalmente, se evidenciaron diferencias según sexo, carrera y nivel de satisfacción vocacional.

Abstract: This study sought to design and evaluate a vocational preference test for Business Administration, Materials Engineering and Biotechnology Engineering majors at the Instituto Tecnológico de Costa Rica (ITCR). For this goal, first of all a vocational profile of each career was constructed, from which the test items were written. 480 students took part, with an average age of 22.07 years, 53.19% of them women and 46.81% men. Descriptions of the profile of each career were collected by students and teachers, and later analyzed by expert groups. From the defined profile, items were drawn up and later evaluated with factor analysis, for the selection of the items, obtaining adequate indicators of goodness of fit. The vocational test includes three factors: Skills, Interests and Vocational Tasks. In turn, the Skills scale evaluated six areas: Mathematics, Chemistry, Physics, Biology, Leadership and Self-regulationdiscipline. For its part, the scale of preferences contemplated the three areas evaluated: Administration, Materials and Biotechnology. On the other hand, there were differences according to sex, major and level of vocational satisfaction.

Sistema de tareas docentes integradoras para favorecer la interdisciplinariedad del profesional de la Cultura Física / System of integrative teaching tasks to promote interdisciplinary of the professional of Physical Culture

Resumen El desempeño del profesional de la Cultura Física en el eslabón de base, en Cuba, requiere de una sólida formación interdisciplinaria que la universidad, como ente formador, debe propiciar, sin embargo, no se alcanza en este aspecto los niveles deseados. Ante dicha afirmación, el objetivo de esta investigación es proponer tareas docentes integradoras para favorecer la interdisciplinariedad en el proceso de formación del Licenciado en Cultura Física, desde la asignatura Teoría y metodología de la Educación Física, la cual reviste gran importancia como una vía acertada para conducir la formación, con un carácter interdisciplinario en la Universidad de Ciencias de la Cultura Física y el Deporte "Manuel Fajardo". Con este propósito se, utilizaron los métodos: analítico, sintético, inductivo- deductivo y análisis documental. Los resultados fueron valorados mediante los paquetes estadísticos SPSS v. 20 y Epidat v. 4.2, y la dócima no paramétrica de Wilcoxon, lo cual permitió la elaboración de veinte tareas docentes integradoras, que fueron validadas como resultado del criterio de treinta expertos y constituyen una alternativa de solución al problema revelado en la investigación. Se corroboró a través de un preexperimento pedagógico, realizado en el tercer año del curso académico 2017-2018.

Abstract The performance of the Physical Culture professional in the base link in Cuba requires a solid interdisciplinary formation that the university as a training entity must propitiate; however, the desired levels are not reached in this aspect. In view of this affirmation, the objective of this research is to propose integrative teaching tasks to favor interdisciplinarity in the process of formation of the Bachelor in Physical Culture, from the subject Theory and Methodology of Physical Education, which is of great importance as an appropriate way to conduct the formation with an interdisciplinary character in the University of Sciences of Physical Culture and Sport "Manuel Fajardo". For this purpose, the following methods were used: synthetic analytic, deductive inductive, documentary analysis. The results were evaluated through the statistical packages SPSS v. 20 and Epidat v. 4.2, and Wilcoxon's nonparametric docima, which allowed the elaboration of twenty integrative teaching tasks, which were validated as a result of the criteria of thirty experts and constitute an alternative solution to the problem revealed in the research. It was corroborated through a pre-pedagogical experiment carried out in the third year of the 2017-2018 academic year.
