The germicidal system is constructed using a UVC LED illumination module with a wavelength of 275 nm and a power of 1.8 mw. UVC LED has a smaller volume without heat radiation and pollution that meets the requirements of green energy and environmental protection. It is very suitable for sterilization and purification. It can destroy microbiological organisms such as bacteria, viruses, or spores, etc., of their molecular structure of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) in pathogen cells, which causes the cells to lose the ability to replicate and regenerate, thereby achieving germicidal efficacy. The UVC Germicidal System (abbreviated as UVCGS) is designed with an array of UVC LEDs. The key technologies of the UVCGSs' drive circuit is a new automatic power control system (APC) design, which can make UVC LED in constant current mode and stable electric power for operation. That is, when the power of the UVC LED changes with temperature, the current amount can be automatically adjusted by the driving circuit. So that the UVC LED can be maintained at a different temperature and still keep a stable optical power output to achieve temperature compensation purpose. The design of the drive circuit confirms that the UVCGS being operated at different temperature changes from 0 °C ~ 35 °C and with stable current and stable optical power output capability can sterilize Escherichia coli, Staphylococcus aureus, Acinetobacter baumannii, etc., achieving multiple germicidal benefits. Among them, Acinetobacter baumannii has been experimentally analyzed that within 2–20 seconds of irradiation time, under the condition of average sterilization residual amount at different heights, the proper bactericidal residual amount is about 12–13 (lethal rate is 91-92%, $text{UVGI}=12$), and the required minimum germicidal irradiation power dose is $1500mu text{W}$- Sec/cm2, which meets UVGI standard values and typical lethality standards.
该杀菌系统采用波长275 nm、功率1.8 mw的UVC LED照明模块构建。UVC LED体积小,无热辐射和污染,符合绿色能源和环保的要求。非常适合杀菌、净化。它能破坏病原体细胞中细菌、病毒或孢子等微生物的DNA(脱氧核糖核酸)和RNA(核糖核酸)的分子结构,使细胞失去复制和再生的能力,从而达到杀菌效果。UVC杀菌系统(缩写为UVCGS)是用一组UVC led设计的。UVC LED驱动电路的关键技术是一种新型的自动电源控制系统(APC)设计,它可以使UVC LED在恒流模式下稳定地工作。即当UVC LED的功率随温度变化时,可以通过驱动电路自动调节电流的大小。使UVC LED在不同温度下都能保持稳定的光功率输出,达到温度补偿的目的。驱动电路的设计确认UVCGS被操作在不同的温度变化从0°C ~ 35°C和稳定电流和稳定的光功率输出能力可以消毒大肠杆菌,金黄色葡萄球菌,鲍曼不动杆菌,等,实现多种杀菌的作用。其中,鲍曼不动杆菌经实验分析,在照射时间2-20秒内,在不同高度的平均杀菌残留量条件下,适宜的杀菌残留量约为12 - 13(致死率为91-92%,$text{W}$- Sec/cm2),所需的最小杀菌辐照功率剂量为$1500mu text{W}$- Sec/cm2,满足UVGI标准值和典型致死标准。

Liu Jen-Min
On January 18, 2019, the Tourism News issued by the Tourism Bureau of the Ministry of Communications announced that during the period from June 29, 2018 to January 17, 2019, there were 8 licenses for the travel agencies and 30 applicants for dismissal. However, looking at the development of the current tourism industry, it has become the core and trend of economic development in all countries of the world. The Taiwan government has no exceptions. The tourism industry is listed as one of the six key policy policies. The travel agencies has a leading position in the development of the tourism industry. Although the operating companies all face the normal phenomenon of setting up and closing down, the travel agencies has such a high ratio of companies in just half a year, facing the fate of closure, which may not be a single industry. The normal phenomenon, whether serious people will affect other enterprises, and the chain reaction of social problems, must be carefully ignored and dealt with. After discovering this abnormal situation from this tourism news, the researcher has aroused the research motive. He is scheduled to give research on the current status of the travel agencies, hope to find the problem, and make a conclusion and suggestion report, in order to make reference to the official academic research community. This study mainly uses the methods of individual interviews and statistical analysis methods to access a number of relevant public associations and key players in business operations. In order to ensure the correctness of the research report, the interviewees operate in northern and central Taiwan. In the southern and other regions, companies include large, medium and small companies. The categories include sales and direct sales. The researchers first asked the respondents to do basic personal information and current status of the travel agencies. The respondents will answer the questions in an open-ended manner, and use the exploration method for the content of the reply, and then conduct more in-depth interviews. The researcher gave the recording and verbatim writing of the text of the respondent's arguments. After the data was written and compiled, coded, classified, and then researched and analyzed, the research report was written.
2019年1月18日,交通部旅游局发布的《旅游新闻》公布,2018年6月29日至2019年1月17日期间,旅行社领取许可证8张,申请解聘30人。但是,纵观当前旅游业的发展,它已经成为世界各国经济发展的核心和趋势。台湾政府也不例外。旅游业被列为六大重点政策之一。旅行社在旅游业的发展中处于领先地位。虽然运营公司都面临着正常的兴办倒闭现象,但旅行社在短短半年的时间里就有如此高的公司比例,面临倒闭的命运,这可能不是一个单一的行业。正常的现象,严重的人是否会影响到其他企业,以及连锁反应的社会问题,必须谨慎忽视和处理。研究者从这则旅游新闻中发现了这种不正常的情况,从而激发了研究动机。他计划对旅行社的现状进行研究,希望能发现问题,并做出结论和建议报告,以供官方学术研究界参考。本研究主要采用个别访谈的方法和统计分析的方法,访问了一些相关的公共协会和企业运营的关键参与者。为了保证研究报告的正确性,受访者在台湾北部和中部进行操作。在南方和其他地区,公司包括大、中、小型公司。分类包括销售和直销。研究人员首先询问了受访者的基本个人信息和旅行社的现状。受访者将以开放式的方式回答问题,并对回答的内容采用探究式的方法,然后进行更深入的访谈。研究人员对答辩人的论点进行了录音和逐字逐句的书写。在对数据进行编写、编译、编码、分类、研究和分析后,撰写研究报告。

The LOHAS Digital and Interactive Vitalization Community for Heritage and Sustainability of The Ruins of St. Paul 圣保罗遗址遗产与可持续发展LOHAS数字化互动活化社区
Peng-Wei Hsiao
Macau is a tourist city with its distinctive architecture and attractions. The development of the gaming industry has attracted many tourists to travel to the area. One of the most famous landmark in Macau is the Ruins of St. Paul. The 100-year-old historical monument just reserved a wall after three major fire and reconstructions and standing outside rely on human maintenance. Therefore, sustainable preservation is an important issue today. Users can quickly search for historical sites and digitally saved image data through their smart phones. At present, mobile APP rarely uses stereoscopic perspectives for interactive operations. The 4DAGE company's 4DKanKan technology can quickly create virtual reality and save historic site in mobile devices to interact with it. The 4DKanKan can also integrate mobile guide and navigation. Therefore, this study intends to use this technology to design and link to the Web. It can continue to extend to other attractions or museum collections in the future. There are systematic and digital representations of different types of monuments that have the concept of sustainable management.
澳门是一个旅游城市,拥有独特的建筑和景点。博彩业的发展吸引了许多游客到该地区旅游。澳门最著名的地标之一是圣保罗遗址。这座有着100年历史的历史遗迹在经历了三次大火和重建后只保留了一堵墙,站在外面依靠人工维护。因此,可持续保护是当今的一个重要问题。用户可以通过智能手机快速搜索历史遗迹和数字保存的图像数据。目前,手机APP很少使用立体视角进行交互操作。4age公司的4DKanKan技术可以快速创建虚拟现实,并将历史遗迹保存在移动设备中与之交互。4DKanKan还可以集成移动指南和导航功能。因此,本研究打算利用该技术来设计和链接到Web。它可以在未来继续扩展到其他景点或博物馆藏品。不同类型的古迹有系统的和数字化的表现形式,具有可持续管理的概念。

The Factors that Cause a Reduction of Energy Intensity in the Industrial Sectors of Inner Mongolia 内蒙古工业部门能源强度降低的影响因素
Sheng-wen Tseng, Sabrina Habich-Sobiegalla
This article analyses the factors that cause a reduction of energy intensity in the industrial sectors of Inner Mongolia. By constructing a decomposition model, this study explores the contributions of energy conservation and industrial structure policies to energy consumption between 2005 and 2016. This study concluded that the reduction of energy consumption share and enhancing the energy efficiency of industry sector and transportation, storage, post & telecommunication services sector is the core issue for the reduction of energy intensity in Inner Mongolia. The adjustment of industrial structure is another driving factor; however its effect is obviously less than that of the effect of energy intensity itself.

Application of chemometric preprocessing and achromatic lens in hyperspectral imaging for assessment of uneven wound 化学预处理和消色差透镜在高光谱成像评估不均匀伤口中的应用
Yi-Ting Wu, Kan-Yu Lin, Cheng Lu, Kai-Yu Wang, Wei‐Min Liu
Hyperspectral imaging (HSI) uses contiguous spectral channels to collect images under different wavelengths. It is known that this spectral information can be used for material differentiation or identification. However, different sample preparation methods, lighting conditions, distance, and sample morphology will cause huge variations in the collected spectra. In this study, we performed clustering analysis on a HSI data of an elbow area, which is roughly a spherical surface rather than a flat surface. Chemometric preprocessing (CMPP) developed in spectroscopy is applied on the HSI data to reduce the morphology-induced spectral variation. A hardware approach, installing an achromatic lens, is also adopted for comparison. Positive results indicated that the with CMPP and certain spectral measures in clustering could be helpful for wound assessment using HSI.
高光谱成像(HSI)利用连续的光谱通道采集不同波长的图像。众所周知,这种光谱信息可用于物质的鉴别或鉴定。然而,不同的样品制备方法、光照条件、距离和样品形态会导致采集到的光谱发生巨大变化。在这项研究中,我们对肘关节区域的HSI数据进行了聚类分析,肘关节区域大致是一个球面而不是一个平面。将光谱学中发展起来的化学计量预处理(CMPP)应用于HSI数据,以减少形貌引起的光谱变化。另外,还采用了安装消色差透镜的硬件方法进行比较。阳性结果表明,CMPP和一定的光谱测量在聚类中可以帮助HSI评估伤口。

Evaluation of Mental Stress and Heart Rate Variability Derived from Wrist-Based Photoplethysmography 基于腕关节的光电容积脉搏图对精神压力和心率变异性的评价
Chongyan Chen, Chun-hung Li, Chih-Wei Tsai, Xinghua Deng
Heart Rate Variability (HRV) is a significant indicator of physical fitness and mental stresses. Electrocardiography (ECG) is the most common means to detect HRV. However, the nature of the ECG detection limits its convenience and usage time. While wrist-based Photoplethysmography (PPG) provides the possibility of convenient 24/7 HRV monitoring, its accuracy has not been systematically analyzed. We experimented with six healthy subjects and measured PPG from their wrist and ECG from their chest. The result shows that ten HRV parameters have significant differences between stress and non-stress states. Furthermore, the 10-fold accuracy of stress state detection within subjects is 98% and the Leave-One-Participant-Out F1score reaches 80%. The results demonstrate that wrist-based PPG can provide HRV measurements that enable the recognition of mental stress as accurately as ECG, even for a short three-minute temporal window.
心率变异性(HRV)是身体健康和精神压力的重要指标。心电图(ECG)是检测HRV最常用的手段。然而,心电检测的性质限制了它的便捷性和使用时间。虽然基于手腕的光电容积脉搏波(PPG)提供了方便的24/7 HRV监测的可能性,但其准确性尚未得到系统的分析。我们对6名健康受试者进行了实验,并测量了他们手腕上的PPG和胸部的ECG。结果表明,在应力状态和非应力状态下,10个HRV参数存在显著差异。此外,被试内部压力状态检测的10倍正确率为98%,leave - one - participants out f1得分达到80%。结果表明,基于手腕的PPG可以提供HRV测量,能够像ECG一样准确地识别精神压力,即使是短暂的三分钟时间窗口。

Analysis of Dynamic Cardiopulmonary Signals and Heart Rate Variability for Distinct Cardiopulmonary Fitness Norms under Graded Exercise and Recovery Periods 分级运动和恢复期下不同心肺适能标准的动态心肺信号和心率变异性分析
C.K. Chen, S. Lin, C.Y. Huang, T.C. Wang, T. Yao, C.L. Wu
This study performed a comparison based on electrocardiogram (ECG) signals for participants with distinct levels of cardiopulmonary fitness at graded exercise intensities. The participants were university freshmen with cardiopulmonary fitness norms in the bottom 20%, middle, and top groups. Cardiopulmonary signals were acquired under the rest condition, at three graded exercise levels, and in subsequent recovery periods. Time domain and spectral analyses were performed to study the principal components of heart rate variability (HRV) from recorded ECG signals. The results showed that the frequency domain measures TP, HF, nLF, nHF, and LF/HF of the HRV indices all exhibit significant differences between the three groups.
本研究基于不同心肺健康水平的参与者在分级运动强度下的心电图(ECG)信号进行了比较。参与者是大学新生,他们的心肺健康水平处于倒数20%、中间和前三组。在休息条件下,在三个分级运动水平下以及随后的恢复期获得心肺信号。采用时域和频谱分析方法研究了记录心电信号中心率变异性的主成分。结果表明,三组HRV指标的频域测量TP、HF、nLF、nHF和LF/HF在三组间均有显著差异。

The participants were university freshmen with cardiopulmonary fitness norms in the bottom 20%, middle, and top groups. Cardiopulmonary signals were acquired under the rest condition, at three graded exercise levels, and in subsequent recovery periods. Time domain and spectral analyses were performed to study the principal components of heart rate variability (HRV) from recorded ECG signals. The results showed that the frequency domain measures TP, HF, nLF, nHF, and LF/HF of the HRV indices all exhibit significant differences between the three groups.","PeriodicalId":165579,"journal":{"name":"2019 IEEE Eurasia Conference on Biomedical Engineering, Healthcare and Sustainability (ECBIOS)","volume":"368 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115175946","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}
