Majority of musculoskeletal injuries located in the shoulder are often due to repetitive or sustained movements which occur in work routines in different areas. In the case of workers in the construction sector, repetitive routine and movements under load produce displacements and unnatural postures of the shoulder joint. For this reason, the objective of this study is to model in 3D the biological elements that form the shoulder joint for subsequent Finite Element Analysis (FEA). Three cases of different loads have been considered in this first study. With the analysis developed, and thanks to the linear and isotropic joint approach has been possible to evaluate the stresses in the elements: muscles, tendons and ligaments. The methodology used allowed to obtain an improved mesh of the shoulder joint to analyze real situations with FEM analysis with applications in the field of sports medicine, work, etc. Furthermore, the simplification adopted for the modeling of the joint muscles, as 1D elements in FEM, has made it possible to establish different positions of the human joint without having mesh again each one of the positions that can be studied. The results are consistent with the states of applied loads.
大多数位于肩部的肌肉骨骼损伤通常是由于在不同区域的日常工作中发生的重复或持续的运动。就建筑行业的工人而言,重复的日常工作和负荷下的运动导致肩关节位移和不自然的姿势。因此,本研究的目的是为后续的有限元分析(FEA)建立形成肩关节的生物元件的3D模型。在第一项研究中考虑了三种不同载荷的情况。随着分析的发展,由于线性和各向同性的关节方法已经有可能评估元素的应力:肌肉,肌腱和韧带。所采用的方法可以得到一个改进的肩关节网格,用有限元法分析实际情况,在运动医学、工作等领域有广泛的应用。此外,关节肌肉建模采用的简化方法,作为有限元中的一维单元,使得可以建立人体关节的不同位置,而无需再次网格化每个可以研究的位置。结果与外加荷载的状态一致。

Importance of auditory development in conservatory students and its repercussion in the learning of another language: Case study 音乐学院学生听觉发展的重要性及其对外语学习的影响:个案研究
Rocío Chao-Fernández, Ruth Alonso-Jartín, Aurelio Chao-Fernández
This research analyses the benefits of Music in improving the learning of a foreign language. A theoretical review was carried out about the importance of musical training in the learning of other languages and the importance of starting it in the earliest possible way. Subsequently, a study was conducted with conservatory students about their perception of whether studying music helps them learn languages. A questionnaire of seventeen items was applied. After the analysis of the results, we can conclude that there are many positive aspects that music contributes to the learning of a second language, since it helps to improve auditory discrimination, to improve pronunciation and to automate the process of language acquisition, even though not all students are aware of this.

Specialized services for students with special educational needs in the Spanish education system 为西班牙教育系统中有特殊教育需要的学生提供专门服务
M. Vieira, Sara González-Tejerina
Educational guidance in Spain is organized as an institutionalized network of internal and external services at the education system in order to guarantee attention to the diversity of students. The aim of this study is to assess the offer of guidance services in Spain, focusing on services in charge of students with special educational needs. In this study, regulations on educational guidance (n = 51 documents) at Primary Education of the seventeen Autonomous Communities and the Autonomous Cities (Ceuta and Melilla) are analyzed and compared by means of content analyses. Results of this research indicate that the most frequent educational guidance services are, on the one hand, general services known as Educational and Psychopedagogical Guidance Services comprised of counsellors that visit schools on part-time basis and offer their services to the general population of students and, on the other hand, specialized services for students with special educational needs due to specific disabilities or disorders. As a new tendency, full-time internal educational guidance units have emerged at schools in 6 Autonomous Communities that substitute or coexist with Educational and Psychopedagogical Guidance Services. The main conclusion of this study is that, although there is a fairly common structure at national level regarding educational guidance services for mainstream students, there is certain heterogeneity of services for students with special educational needs in terms of types of disabilities, organization, functions and characteristics.
西班牙的教育指导是作为教育系统内部和外部服务的制度化网络组织起来的,以保证对学生多样性的关注。本研究的目的是评估西班牙提供的指导服务,重点关注有特殊教育需要的学生。本研究采用内容分析的方法,对17个自治区和自治区(休达和梅利利亚)的小学教育指导条例(n = 51份文件)进行分析比较。这项研究的结果表明,最常见的教育指导服务一方面是一般服务,即教育和心理指导服务,由兼职访问学校的辅导员组成,向普通学生提供服务,另一方面是为由于特殊残疾或障碍而有特殊教育需要的学生提供专门服务。作为一种新的趋势,在6个自治区的学校中出现了专职的内部教育指导单位,替代或并存于教育和心理辅导服务。本研究的主要结论是,虽然主流学生的教育指导服务在全国范围内具有较为普遍的结构,但特殊教育需要学生的服务在残疾类型、组织、功能和特征等方面存在一定的异质性。

Kahoot, win the learning race Kahoot,赢得学习竞赛
Vanessa Izquierdo-Álvarez, Eva Lahuerta-Otero, Rebeca Cordero-Gutiérrez
With the arrival of the millennials and generation Z to the university classrooms, the greatest teaching challenge is to adapt the traditional masterclass and turn the classroom into a collaborative space that takes advantage of Information and communication technology to introduce dynamic elements that encourage the participation of increasingly unmotivated students. With the emergence and penetration of mobile devices in all aspects of everyday life, the teaching-learning process must be changed to encourage participation and to achieve effective results. Thus, the use of gamification tools such as Kahoot can help in this challenge, as they encourage the effective acquisition of competences through play and competition. This study demonstrates the positive results of including gamification processes in the Spanish public and private university classroom, contrasting their effectiveness in different degrees and subjects.
随着千禧一代和Z一代进入大学课堂,最大的教学挑战是调整传统的大师班,将课堂变成一个利用信息和通信技术的协作空间,引入动态元素,鼓励越来越缺乏动力的学生参与。随着移动设备在日常生活的各个方面的出现和渗透,教学过程必须改变,以鼓励参与并取得有效的结果。因此,像Kahoot这样的游戏化工具能够帮助玩家应对这一挑战,因为它们能够鼓励玩家通过游戏和竞争有效地获取技能。本研究展示了将游戏化过程纳入西班牙公立和私立大学课堂的积极结果,对比了它们在不同学位和科目上的有效性。

Exploring students psychophysiological stress response in physiotherapy 探讨学生在物理治疗中的心理生理应激反应
Ana Isabel Beltrán-Velasco, Pablo Ruisoto, Alberto Bellido-Esteban, Mónica García-Mateos, V. Clemente-Suárez
The aim of this study was to analyze the psychophysiological response of Physiotherapy degree students during a complete clinical practice. We analyzed in 15 students heart rate variability (HRV) to analyze autonomic modulation in three moments during the entire clinical practices of 3 months (4 h per day, 3 days per week), first session, middle session and last session; perceived stress, personality, life engagement, cognitive flexibility before starting the clinical practice the academic performance after the clinical practice. Results based on HRV and related indexes parameters fail to indicate the expected autonomic adaptation during the practice. A complete clinical practice of Physiotherapy degree students does not produce a habituation process since a high sympathetic autonomic nervous system modulation was measured in the beginning, at the middle and at the final of the clinical practice.
本研究的目的是分析物理治疗专业学生在完整的临床实习期间的心理生理反应。我们分析了15名学生的心率变异性(HRV),分析了3个月(每天4小时,每周3天),第一阶段,中期和最后阶段的整个临床实践中的三个时刻的自主调节;临床实习前的感知压力、人格、生活投入、认知灵活性、临床实习后的学习成绩。在实践中,基于HRV和相关指标参数的结果未能显示预期的自主适应。一个完整的物理治疗学位学生的临床实践并不会产生一个习惯化过程,因为在临床实践的开始、中期和最后都测量了高度的交感自主神经系统调节。

Decision support tools for SLR search string construction 单反搜索字符串构建的决策支持工具
Samuel Marcos, F. García-Peñalvo
Systematic literature reviews (SLRs) have gained popularity during the last years as a form of providing state of the art about previous research. As part of the SLR tasks, devising the search strategy and particularly finding the right keywords to be included in the search string is a difficult and critical step, as it will determine what evidence will be identified in the different searched sources and thus condition the rest of the review. In order to support the search process, this paper presents an iterative methodology for search string construction along with a set of decision support tools that help in building the search string by finding appropriate key terms related to the topic of interest in order to assist the researcher in the SLR conduction.
在过去的几年里,系统文献综述(slr)作为一种提供先前研究的艺术状态的形式得到了普及。作为SLR任务的一部分,设计搜索策略,特别是找到要包含在搜索字符串中的正确关键字是一个困难和关键的步骤,因为它将决定在不同的搜索来源中识别哪些证据,从而影响审查的其余部分。为了支持搜索过程,本文提出了一种迭代的搜索字符串构建方法以及一套决策支持工具,这些工具通过寻找与感兴趣的主题相关的适当关键字来帮助构建搜索字符串,以协助研究人员进行单反研究。

On the Dental BioTribology: Comparison of Zirconia/Zirconia and Zirconia/Natural Tooth Friction Coefficients by Using a Reciprocating Tribometer 牙齿生物摩擦学研究:用往复摩擦计比较氧化锆/氧化锆和氧化锆/天然牙齿摩擦系数
A. Ruggiero, R. D’Amato, L. Sbordone, F. Haro, A. Lanza
In recent years the interest of tribology applied to dentistry is taking on a large scale due to its rapid expansion and growth. Intensive experimental research conducted on dental tribology allows to develop a more detailed understanding of all the phenomena that take part in the phenomenon of tooth wear. The purpose of this work is to investigate tribological performances in the tooth-to-tooth contact and material-to-natural tooth contact (zirconia vs. zirconia and natural tooth vs. zirconia). The tribological tests were carried out by using a reciprocating tribometer under lubricated conditions (artificial saliva). The normal force in these tests was 20 N, and the duration was of 60 min. The stroke length was 2 mm, according to the range of displacement used in scientific literature. The wear mass loss evaluation was evaluated by using a gravimetric method. A topographic analysis was carried with a 3D non-contact optical profiler in order to characterize the wear mechanisms present in the worn surfaces after each of tribo-tests. The results show that the minimum value of the COF is obtained in the case of Zirconia vs. Zirconia tribo-couple, corresponding to 0.49±0.03. In the case of the tooth-tooth couple this value is 0.52 ±0.03. The results on the wear mass loss show a very low wear rate when coupling in tribological condition natural tooth with a ceramic restoration (a mean value of 0.5 mg was found). This rate is even lower when the contact is between two artificial zirconia teeth.
近年来,摩擦学在牙科领域的发展迅速,引起了广泛的关注。对牙齿摩擦学进行深入的实验研究,可以更详细地了解牙齿磨损现象的所有现象。这项工作的目的是研究牙齿与牙齿接触和材料与自然牙齿接触(氧化锆与氧化锆和自然牙齿与氧化锆)的摩擦学性能。在润滑条件下(人工唾液)使用往复式摩擦计进行摩擦学试验。这些试验的法向力为20牛,持续时间为60分钟,行程长度为2毫米,根据科学文献中使用的位移范围。用重量法对磨损质量损失进行了评价。使用三维非接触式光学剖面仪进行地形分析,以表征每次摩擦试验后磨损表面存在的磨损机制。结果表明,氧化锆对氧化锆摩擦偶的COF最小值为0.49±0.03;对于齿-齿耦合,该值为0.52±0.03。磨损质量损失的结果表明,在摩擦学条件下,天然牙与陶瓷修复体耦合时,磨损率非常低(平均值为0.5 mg)。当两颗人造氧化锆牙齿接触时,这一比率甚至更低。

A Preliminary Study of Proof of Concept Practices and their Connection with Information Systems and Information Science 概念验证实践及其与信息系统和信息科学的联系的初步研究
Antonio Jose Rodrigues Neto, M. M. Borges, Licinio Gomes Roque
In this study, we have identified that a Proof of Concept can be characterized as a research practice and instrument of knowledge creation, based on a set of activities that are applied to the study and understanding of certain objects by the actors involved. In Information Systems Development, we have characterized a Proof of Concept as a system that creates socio-technical phenomena and, with the aim of understanding these phenomena, we use the Context Engineering approach. Context Engineering represents the relationship between a set of essential movements in a new framework of activities of Information Systems Development. Furthermore, we highlight Information Science, which allows us to study in formal and rigorous ways the processes, techniques, conditions, and effects that are entailed in improving the efficacy of information, which is used for a range of purposes related to individual, social and organizational needs, as well as new methods of scientific communication. To our knowledge, and following a review of the literature, there is a lack of studies combined with gaps in the knowledge of Proof of Concept practices. The misunderstanding of these practices may strengthen the probability of compromising the reliability, reproducibility, and reusability of the knowledge consumed or constructed in a Proof of Concept, which may affect its appropriate utilization by the organizations, their actors, or communities of practice. In this context, this paper aims to promote a preliminary study of the state-of-the-art scientific knowledge and to contribute to the body of published literature on Proof of Concept practices.
在这项研究中,我们已经确定,概念证明可以被描述为一种研究实践和知识创造的工具,它基于一系列活动,这些活动被相关参与者应用于研究和理解某些对象。在信息系统开发中,我们将概念验证描述为创建社会技术现象的系统,并且为了理解这些现象,我们使用上下文工程方法。上下文工程代表了信息系统开发活动的新框架中一组基本运动之间的关系。此外,我们强调信息科学,它使我们能够以正式和严格的方式研究提高信息有效性所需的过程、技术、条件和效果,这些信息用于与个人、社会和组织需求相关的一系列目的,以及科学交流的新方法。据我们所知,在回顾文献之后,缺乏与概念证明实践知识差距相结合的研究。对这些实践的误解可能会加强在概念证明中消耗或构建的知识的可靠性、可重复性和可重用性的妥协可能性,这可能会影响组织、其参与者或实践社区对其的适当利用。在此背景下,本文旨在促进对最先进的科学知识的初步研究,并为已发表的关于概念证明实践的文献做出贡献。

In Information Systems Development, we have characterized a Proof of Concept as a system that creates socio-technical phenomena and, with the aim of understanding these phenomena, we use the Context Engineering approach. Context Engineering represents the relationship between a set of essential movements in a new framework of activities of Information Systems Development. Furthermore, we highlight Information Science, which allows us to study in formal and rigorous ways the processes, techniques, conditions, and effects that are entailed in improving the efficacy of information, which is used for a range of purposes related to individual, social and organizational needs, as well as new methods of scientific communication. To our knowledge, and following a review of the literature, there is a lack of studies combined with gaps in the knowledge of Proof of Concept practices. The misunderstanding of these practices may strengthen the probability of compromising the reliability, reproducibility, and reusability of the knowledge consumed or constructed in a Proof of Concept, which may affect its appropriate utilization by the organizations, their actors, or communities of practice.

Comprehensive analysis of the mass media visual component in the aspect of media aesthetics 从媒介美学的角度综合分析大众传媒的视觉成分
I. Topchii
Today, under the conditions of visual culture domination, the issues of particular text emotional perception by the audience, as well as questions of media aesthetics turn increasingly important. The article uses one of the leading social and political Internet media, in the Russian language, as an empirical basis. This is web-site Meduza, which is also presented in the most popular social network VKontakte, by RuNet. Thematic fields of media content of the public page are identified within the article. There is a classification of visual content, as well as the analysis of comments to the posts. When performing the research, the results of which are presented in this article, the author uses a set of different methods. These are method of continuous sampling; content analysis and discourse analysis; description and generalization. Complex nature of the methodology used here is aimed at deep and complex comprehension of the empirical material.
在视觉文化统治的今天,受众对特定文本的情感感知问题以及媒介美学问题变得越来越重要。这篇文章使用了一个主要的社会和政治网络媒体,在俄语,作为实证基础。这是一个网站Meduza,它也出现在最流行的社交网络VKontakte,由RuNet。公共页面媒体内容的主题领域在文章中确定。有一个视觉内容的分类,以及对帖子评论的分析。在进行研究时,作者使用了一套不同的方法,其结果将在本文中呈现。这些是连续抽样法;内容分析与话语分析;描述和概括。这里使用的方法的复杂性是为了深入而复杂地理解经验材料。
