The rise of Information Technology has impacted not only on the way of doing business and the digital transformation of organizations, but also on the sustainability, acquiring a special relevance through the idea of the Green IT. The Green IT is becoming an indispensable area in organizations and in a social demand. However, organizations do not have the necessary mechanisms to assess their maturity and improve in this area. Therefore, the objective of the present study is to carry out a systematic mapping study to compile the state of the art of the maturity models of sustainability, and, in particular, of Green IT, in order to establish a guide to develop a maturity model of Green IT. The results obtained demonstrate the novelty of the area and the lack of a solid Green IT maturity model and, therefore, the need to elaborate and validate a model of this type.
信息技术的兴起不仅影响了经营方式和组织的数字化转型,而且影响了可持续性,通过绿色IT的理念获得了特殊的相关性。绿色IT正在成为组织和社会需求中不可或缺的领域。然而,组织没有必要的机制来评估它们在这方面的成熟度和改进。因此,本研究的目的是进行系统的映射研究,以汇编可持续发展成熟度模型的最新进展,特别是绿色IT的成熟度模型,以建立绿色IT成熟度模型的开发指南。获得的结果证明了该领域的新颖性和缺乏可靠的绿色IT成熟度模型,因此需要详细说明和验证这种类型的模型。

3D printing is a production process that has existed for three decades but its massive appearance is more recent. RepRap is a project created with the goal that more people have access to a open source low cost 3D printer. This research has been conducted based on knowledge shared by this community following their guidelines in order to take a step forward in the development of technology and cooperate with their spreading. The research has developed a prototype with a more flexible control system that allows the user a real-time control and video monitoring of the 3D printer processes through a browser from anywhere in the LAN, the control system is deployed in a reduced size computer called Raspberry Pi which could replace a PC, this control is done by implementing a print server installed on a credit card-sized single-board computer called Raspberry Pi which replace a PC and is integrated in the printer case with all the benefits generated such as the mobility an independency from other.
3D打印是一种已经存在了30年的生产工艺,但它的大规模出现是最近的事情。RepRap是一个项目,其目标是让更多的人能够使用开源的低成本3D打印机。这项研究是基于这个社区分享的知识,遵循他们的指导方针进行的,目的是在技术发展方面迈出一步,并与技术的传播合作。该研究已经开发出一种具有更灵活控制系统的原型,允许用户在LAN的任何地方通过浏览器实时控制和视频监控3D打印机的过程,该控制系统部署在一个名为树莓派的小型化计算机中,可以取代PC。这种控制是通过实现一个打印服务器来完成的,它安装在一个信用卡大小的单板计算机上,叫做树莓派,它取代了PC,并集成在打印机机箱中,带来了所有的好处,比如移动性和独立性。

Open access scientific journals allow scientific information to be published on the Web. Open access is immediate access, without registration, subscription or payment requirements to online digital material free of most of the restrictions imposed by traditional copyright. When talking about open access, it is often indicated that it is "barrier-free" access. However, the access barriers faced by people with disabilities often persist. Open access is access free of technical, legal or financial restrictions. Websites that provide open access must meet web accessibility standards in order to minimize the barriers that impede access to information for people with disabilities. However, web developers often do not have the knowledge to meet web accessibility standards. Several evaluation tools have been developed to verify that a website complies with web accessibility standards. In this article we present the results of an analysis of the web accessibility of 101 websites of scientific journals with open access in Latin America. EXaminator has been used as an automatic evaluation tool to detect the most important problems of web accessibility. The results show that most of the top page of the websites analyzed do not meet web accessibility standards. Finally, based on the results obtained, some recommendations are offered to help improve the accessibility of this type of websites.
开放获取的科学期刊允许科学信息在网络上发布。开放获取是对在线数字材料的即时访问,不需要注册、订阅或付费,不受传统版权施加的大多数限制。当谈到开放获取时,通常会指出它是“无障碍”的获取。然而,残疾人面临的无障碍障碍往往仍然存在。开放获取是指不受技术、法律或财务限制的获取。提供开放访问的网站必须符合网络可访问性标准,以尽量减少阻碍残疾人获取信息的障碍。然而,web开发人员通常不具备满足web可访问性标准的知识。已经开发了几个评估工具来验证网站是否符合网页可访问性标准。在本文中,我们对拉丁美洲101个开放获取科学期刊网站的网络可访问性进行了分析。examator已经被用作一个自动评估工具来检测网页可访问性的最重要问题。结果表明,大多数被分析网站的首页不符合网页可访问性标准。最后,根据所获得的结果,提出了一些建议,以帮助提高这类网站的可访问性。

Important research efforts have been directed over the past ten years, towards exploring alternative parts of the electromagnetic spectrum that could potentially offload a large portion of the network traffic from the overcrowded radio frequency (RF) domain. Due to the latest improvements, the optical wireless communication (OWC) proves to be a viable alternative solution to the issues of forthcoming radio frequency RF spectrum crisis, especially in certain places and situations. Currently, most mobile data traffic is consumed indoor, where light fidelity (LiFi) which is related to visible light communication (VLC) offers lots of specific advantages, and effective solutions to the many issues of wireless communication. The current paper summarizes most of the research, developments and applications achieved so far and looks at the different aspects of the strengths and weaknesses, implementations, challenges, VLC IEEE standard and data modulation techniques of the VLC and specific LiFi's new coined optical wireless communication technology.
在过去的十年里,重要的研究工作一直在探索电磁频谱的替代部分,这些部分可能会从过度拥挤的射频(RF)领域中卸载大部分网络流量。由于最新的改进,光无线通信(OWC)被证明是解决即将到来的射频射频频谱危机问题的可行替代方案,特别是在某些地方和情况下。目前,大多数移动数据流量都是在室内消耗的,其中与可见光通信(VLC)相关的光保真(LiFi)提供了许多特定的优势,并有效地解决了无线通信的许多问题。本文总结了迄今为止所取得的大部分研究、发展和应用,并从不同的方面探讨了VLC的优缺点、实现方法、面临的挑战、VLC的IEEE标准和数据调制技术以及具体的LiFi新创造的光无线通信技术。

The artificial vision is a part of the artificial intelligence that pretends to simulate the human vision, is to say, from the acquisition, processing, analysis and interpretation of images through an intelligent system. This work presents the creation of prototypes under the game jam model as a software product. In this context, the objective of the present work was to apply basic artificial vision algorithms such as linear discriminant analysis (LDA), principal component analysis (PCA), Fisherface, Otsu, CamShift and color spaces such as RGB and HSV in order to be able to motion detection of objects, face recognition and pedestrian detection. As a result of applying this model in rapid prototyping, we found significant factors (such as: participatory design, light construction, product value approach, aesthetics and technology) in the implementation of innovative strategies in creating of prototypes focused on Software development.
人工视觉是假装模拟人类视觉的人工智能的一部分,即通过智能系统对图像进行采集、处理、分析和解释。这项工作将游戏jam模型下的原型作为软件产品呈现出来。在此背景下,本研究的目的是应用基本的人工视觉算法,如线性判别分析(LDA)、主成分分析(PCA)、fishface、Otsu、CamShift和颜色空间(如RGB和HSV),以便能够对物体进行运动检测、人脸识别和行人检测。作为在快速原型中应用该模型的结果,我们发现了在创建专注于软件开发的原型的创新策略的实施中的重要因素(例如:参与式设计、轻结构、产品价值方法、美学和技术)。

Education professionals are always searching for new ways of promoting learning, either by modifying the pedagogical project of courses or by the adoption of new learning strategies. In particular, this paper presents the results of an effort in order to bridge the knowledge acquired by students within classroom in face-to-face classes with technical skills required in real life situations. The contribution presented in this paper is the result of an assignment applied within an undergraduate Data Network Infrastructure Design course in a Brazilian university using an adapted Problem-Based Learning methodology (PBL), as a motivational tool. This paper also presents and discusses the resulting data related to the learning assessment.

In a society where smartphones and mobile connectivity increasingly act as mediators and enhancers of social ties, we can identify technological solutions that bring new challenges to the user, particularly in the way he interacts and communicates with others. This article, by focusing on mobile apps that promote social and loving ties between strangers (Tinder, Bumble, Grindr, etc.), driven by a swipe-based interaction paradigm, aims to explore new challenges, that not only imply technical and operational skills, but also particular habits of interaction (the so-called "swipe culture"). These new behaviours, that include choices and interactions made by the users (actions like accept, discard and/or moving to the next user), as well as the standardized and algorithmically mediated choices made by the apps algorithms, brought to life new scenarios related to info-communicational behaviours. Therefore, the swipe culture and user centered design (UCD) triggered these new habits and behaviours, that were made possible by the features offered by mobile dating applications. Finally, these new habits and behaviours revealed new perceptions and trends in how interactions and relationships can become more disposable, sterile and standardized in the described context.
在智能手机和移动连接日益成为社会联系中介和增强者的社会中,我们可以确定给用户带来新挑战的技术解决方案,特别是在他与他人互动和沟通的方式方面。这篇文章将着眼于那些促进陌生人之间的社交和爱的联系的手机应用(Tinder, Bumble, Grindr等),这些应用基于滑动的交互模式,旨在探索新的挑战,这不仅意味着技术和操作技能,还意味着特定的交互习惯(所谓的“滑动文化”)。这些新的行为,包括用户做出的选择和交互(比如接受、丢弃和/或转移到下一个用户),以及应用程序算法做出的标准化和算法调解的选择,带来了与信息交流行为相关的新场景。因此,刷屏文化和以用户为中心的设计(UCD)引发了这些新的习惯和行为,这些都是由移动约会应用程序提供的功能实现的。最后,这些新的习惯和行为揭示了新的观念和趋势,即在所描述的背景下,互动和关系如何变得更加一次性、无菌和标准化。

This research work is aimed at the estimated two regression models, with which it is intended to measure the fragility of Ecuadorian companies. Development and scope of the proposed objective, the information in the financial statements of 34.575 both large companies are used, medium, small and micro enterprises that are controlled and monitored by the Superintendency of Companies in 2013, plus a selection of be held companies for the development of this work because the account information is limited for some companies in the total sample used in this study is of 22,854 companies. The methodology used in this work is to estimate two models of discrete selection: Logit and Probit. With the information available balance sheet financial indicators were useful as explanatory variables in the models posed regression, from which relevant financial ratios such as ROA, ROE and liquidity are identified were built, use is also made of financial gaps of patrimonio-debt and cash for measuring the fragility of companies. The results show a negative influence Slacks used, as in this case increase the fragility of Ecuadorian companies into bankruptcy, a positive value of ROA equally evidence the probability of default on payment obligations as they thus it reduces profitability increases the fragility of a company into bankruptcy, while a positive value of ROE reduces the brittleness of the company.
这项研究工作是针对估计的两个回归模型,它的目的是衡量厄瓜多尔公司的脆弱性。发展和提出的目标范围,在财务报表中的信息34.575大公司被使用,中小微企业的监管公司在2013年的控制和监测,加上选择他持有的公司的发展这项工作,因为一些公司的账户信息是有限的,在本研究中使用的总样本是22,854家公司。在这项工作中使用的方法是估计离散选择的两个模型:Logit和Probit。利用现有的信息,资产负债表财务指标可以作为模型回归中的解释变量,从中确定相关的财务比率,如ROA, ROE和流动性,还使用继承债务和现金的财务缺口来衡量公司的脆弱性。结果显示了Slacks使用的负面影响,因为在本例中增加了厄瓜多尔公司破产的脆弱性,正值的ROA同样证明了支付义务违约的概率,因为它们降低了盈利能力,增加了公司破产的脆弱性,而正值的ROE降低了公司的脆弱性。

In this article we approach the current state of art regarding programming education. We analyze the current constraints and challenges that students have been facing when learning programming, as well as the methodologies adopted by teachers and researchers to overcome these adversities. We propose the implementation of gamification to motivate and encourage students to achieve better results and to learn efficiently. To that end, the main characteristics of a gamified system are described, as well as the principles of its implementation.

In a media ecosystem characterized by the increase of competitors, the audience fragmentation and the critics about the lack of independence of public service media, European televisions must redefine their mission, giving value to their public service exercise in the era of convergence. In this sense, public corporations face the challenge of integrating their traditional models and operating logics with more innovative ones derived from technological changes driven by digitization. This article analyses how Radiotelevisión Española applies product and process innovation to its fiction series in order to elucidate the strategies that public Spanish TV is developing in terms of content production and distribution.
在竞争对手增多、受众分化、公共服务媒体缺乏独立性的批评声等媒体生态系统中,欧洲电视必须重新定义自己的使命,在融合时代赋予公共服务活动价值。从这个意义上说,公共企业面临着将传统模式和运营逻辑与数字化驱动的技术变革所产生的更具创新性的模式和运营逻辑相结合的挑战。本文分析了Radiotelevisión Española如何将产品和流程创新运用到其小说系列中,以阐明西班牙公共电视台在内容生产和发行方面的发展策略。
