The use of Information and Communication Technologies (ICT) in people's daily lives to carry out operations or transactions through computer systems or virtual world; brings with it the benefits, challenges and risks associated with using said ecosystem; Therefore, it is necessary to have valid and up-to-date data on indicators and trends of said ecosystem, to have a consolidated mechanism to search for information and proactively analyze the behavior of ICTs. Governments must observe the development of ICT to generate public policies to improve their competitiveness for the benefit of their citizens, electronic businesses must monitor their environment to analyze competition, overcome obstacles and innovate. The maturity of the use of ICTs in countries depends on the level of competitiveness and economic growth. Applying effective digital transformation requires governments to promote the development of ICT. In the region of Latin American countries, particularly in Honduras, there are limitations on the availability of information on the use, benefits, public policies and routes of evolution of ICTs in the transformation and impact that they have had on people's lives and the institutions; In this sense, the collection, processing and publication of statistical data that support to establish goals and indicators in order to observe their behavior and thus be able to make better decisions for the benefit of society becomes key. Implementing an ICT Observatory in Honduras will help improve the government's willingness to implement digital government initiatives.
在日常生活中使用资讯及通讯科技,透过电脑系统或虚拟世界进行操作或交易;带来了与使用上述生态系统相关的利益、挑战和风险;因此,有必要掌握有关上述生态系统的指标和趋势的有效和最新数据,有必要建立一个统一的机制来搜索信息并主动分析信息通信技术的行为。政府必须观察信息通信技术的发展,以制定公共政策,以提高其竞争力,造福其公民,电子企业必须监测其环境,以分析竞争,克服障碍和创新。各国使用信息通信技术的成熟度取决于其竞争力和经济增长水平。实施有效的数字化转型需要政府推动信息通信技术的发展。在拉丁美洲国家区域,特别是在洪都拉斯,信息通信技术的使用、效益、公共政策和发展路线及其对人民生活和机构的影响等信息的可获得性受到限制;从这个意义上说,收集、处理和公布统计数据,以支持建立目标和指标,以便观察他们的行为,从而能够为社会的利益做出更好的决定,这就成为关键。在洪都拉斯实施ICT观察站将有助于提高政府实施数字政府倡议的意愿。

In Panama, in the last 20 years, investment in sanitation has increased both at the State and private levels, driven by the generation of discharge regulations. Although it is true that recovery of the bodies of receiving water is being achieved due to these investments, little has been done with the byproducts of this sanitation, especially the generation of organic sludge or wastewater biosolids. For this reason, our research focused on the study of biochemical methane potential (BPM), through anaerobic digestion tests using the Oxitop system. These results of our research are the results of the evaluation of biosolids from wastewater treatment plants of various economic activities. The findings of the studies of digestivity show that there is a variation in BPM according to economic activity. The maximum BPM values were obtained for municipal biosolids; whose value was 103 mL CH4/g SV. These results are consistent with the contents of similar studies. However, it is required to deepen this subject, with the aim of improving the yields of BPM from wastewater biosolids, by coding, complementing other organic substrates.
在巴拿马,在过去20年里,在排放法规的推动下,国家和私营部门对卫生设施的投资都有所增加。虽然这些投资确实实现了接收水体的回收,但这种卫生设施的副产品,特别是有机污泥或废水生物固体的产生,几乎没有得到处理。因此,我们的研究重点是通过Oxitop系统的厌氧消化测试来研究生化甲烷势(BPM)。这些研究结果是对各种经济活动废水处理厂的生物固体进行评价的结果。消化率的研究结果表明,根据经济活动,BPM存在变化。城市生物固体的BPM值最大;其值为103 mL CH4/g SV。这些结果与类似研究的内容一致。然而,需要深化这一主题,以提高废水生物固体中BPM的产量为目的,通过编码,补充其他有机基质。

This paper engages readers with innovative research methods to learn about popular places in the city. Using locational data of Social Media platforms, including Twitter, Facebook, and Instagram, along with participatory field visits and combining insights from architecture and urban design literature, this study reveals popular socio-spatial clusters in the City of Chicago. Locational data of photographs were visualized by using Geographic Information Systems and helped in producing heat maps that showed the spatial distribution of posted photographs. Geo-intensity of photographs illustrated areas that are most popular visited in the city. The study's results indicate that the city's skyscrapers along open spaces are major elements of image formation. Findings also elucidate that Social Media plays an important role in promoting places; and thereby, sustaining a greater interest and stream of visitors. Consequently, planners should tap into public's digital engagement in city places to improve tourism and economy [1].

Metallic Nanoparticles for Infrared-Blocking Windows 用于红外阻挡窗口的金属纳米颗粒
Pub Date : 2019-10-01 DOI: 10.1109/IESTEC46403.2019.00020

The optical properties of metallic nanoparticles are widely studied in nanooptics due to the multiple applications that can be developed. In this work we explore, by means of numerical simulations, the optical properties of metallic nanoparticles in order to attenuate the infrared radiation in a window. The simulations were carried out by solving the full Maxwell equations using the boundary element method (BEM). Gold, silver and aluminum nanorods were simulated, as well as silver nanotriangles. The simulation results and numerical calculations show a high transmittance in the visible range and a strong attenuation at wavelengths between 700 nm and 1575 nm (which corresponds to most of the infrared radiation coming from the sun) for the case of gold and silver nanorods and for silver nanotriangles. Our results provide useful details for the design of infrared-blocking windows.
金属纳米粒子的光学性质由于其广泛的应用前景,在纳米光学领域得到了广泛的研究。在这项工作中,我们通过数值模拟来探索金属纳米粒子的光学性质,以衰减窗口中的红外辐射。采用边界元法(BEM)求解麦克斯韦方程组进行了数值模拟。模拟了金、银和铝纳米棒,以及银纳米三角形。模拟结果和数值计算表明,对于金、银纳米棒和银纳米三角形而言,在可见光范围内具有较高的透过率,而在波长为700 nm ~ 1575 nm(对应于大部分来自太阳的红外辐射)之间具有较强的衰减。我们的研究结果为红外阻挡窗的设计提供了有用的细节。

Adobe is one of the most widely used materials for housing construction worldwide, because it is low cost and easy to prepare. However, one of its main disadvantages is its low resistance to compression and bending. The addition of natural fibers in the preparation of adobe has been investigated during the last years in order to improve its resistance. Cabuya fiber was added to improve the properties of the adobe units with straw in different percentages. With the fiber addition percentage of 1.75%, the compression resistance improves by 40% and the resistance to bending by 12%.
土坯是世界上最广泛使用的房屋建筑材料之一,因为它成本低,易于制备。然而,它的一个主要缺点是它的抗压缩和抗弯曲能力低。在过去的几年里,为了提高土坯的耐磨性,人们研究了在土坯制备中添加天然纤维。通过添加不同比例的草木纤维,改善秸秆土坯的性能。当纤维添加量为1.75%时,抗压性能提高40%,抗弯曲性能提高12%。

The behavior of five types of welded connections of composite columns rcft (rectangular tube filled with concrete) and type i steel beams used in ecuador, all made with the same materials, dimensions and construction processes, has been compared, modifying the form of the connection, this being the only variable to investigate. By performing experimental cyclic tests following the loading protocol defined by ansi / aisc 341-16, 2016, it was possible to determine the real behavior of these connections, obtain the necessary hysteresis curves, define which test piece of the tested ones presents a better behavior and energy dissipation capacity, as well as analytical models of the tested specimens, were made using finite element methods for comparison.

Analysis of Structural Elements to Promote Social Innovation in Panama 促进巴拿马社会创新的结构要素分析
Pub Date : 2019-10-01 DOI: 10.1109/IESTEC46403.2019.00066

This work compares in a comparative way some advances in the promotion and management of Social Innovation adopted by four Latin American countries, including Panama, in order to generate more knowledge to promote the strengthening and design of new public policies in this ambit. Panama is in the incipient stage of Social Innovation management, compared to the other three countries analyzed: Colombia, Costa Rica and Chile. Among the structural elements addressed are: regulations, the degree of institutionality, mechanisms and incentives to promote social innovation projects and good institutionalized practices. Since 2014, Panama shows its interest and advances in the subject, in the academic and university academic sectors, which can take advantage of social innovation to obtain a greater impact in the country and promote a more inclusive social development. Colombia began efforts to promote Social Innovation in 2007, Chile and Costa Rica in 2014, as well as Panama. These three countries have a higher level of progress in the elements analyzed in their Social Innovation ecosystems than Panama, however, they do not have enough mechanisms to clearly identify the failures that prevent the strengthening of the culture of social innovation and, therefore, the establishment of much more effective public policies.
这项工作以比较的方式比较了包括巴拿马在内的四个拉丁美洲国家在促进和管理社会创新方面所取得的一些进展,以便产生更多的知识,以促进加强和设计这方面的新公共政策。与被分析的其他三个国家:哥伦比亚、哥斯达黎加和智利相比,巴拿马处于社会创新管理的初级阶段。所讨论的结构因素包括:规章、体制程度、促进社会创新项目和良好体制做法的机制和奖励。自2014年以来,巴拿马在学术和大学学术领域表现出对该学科的兴趣和进步,这可以利用社会创新在该国获得更大的影响,促进更具包容性的社会发展。哥伦比亚从2007年开始推动社会创新,智利和哥斯达黎加从2014年开始,巴拿马也是如此。这三个国家在社会创新生态系统中分析的要素方面比巴拿马取得了更高水平的进展,然而,他们没有足够的机制来明确识别阻碍社会创新文化加强的失败,因此,建立更有效的公共政策。

Since 2014, Panama shows its interest and advances in the subject, in the academic and university academic sectors, which can take advantage of social innovation to obtain a greater impact in the country and promote a more inclusive social development. Colombia began efforts to promote Social Innovation in 2007, Chile and Costa Rica in 2014, as well as Panama. These three countries have a higher level of progress in the elements analyzed in their Social Innovation ecosystems than Panama, however, they do not have enough mechanisms to clearly identify the failures that prevent the strengthening of the culture of social innovation and, therefore, the establishment of much more effective public policies.","PeriodicalId":388062,"journal":{"name":"2019 7th International Engineering, Sciences and Technology Conference (IESTEC)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127003495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the course of recent years, the area of information and communication technologies (ICT) is closely related to medicine or health sector, in such a way that the manual processes used in this sector have been automated in order to provide a better quality of life for both the health organization and the patient. This article proposes a mobile application for the monitoring of patients with diabetes problems through an assisted mobile application of a non-invasive glucometer based on the principle of spectrophotometry and photoplethysmography in order that the patient has a better quality of life without having to undergo the usual treatment by invasive glucometers.
近年来,信息和通信技术(信通技术)领域与医学或卫生部门密切相关,在这种情况下,该部门使用的手工流程已实现自动化,以便为卫生组织和患者提供更好的生活质量。本文提出了一种基于分光光度法和光容积脉搏波成像原理,通过辅助移动应用无创血糖仪来监测糖尿病患者的移动应用程序,使患者在无需进行常规的有创血糖仪治疗的情况下,获得更好的生活质量。
