In some hospitals the infusion is still done manually, medical staff observes fluid drip directly and then controls its rate using a mechanical resistor (clamp), this method is certainly far from the level of accuracy. Infusion pump is a medical aid that has functions to control and ensure the correct dose of infusion fluid that is given to patients under treatment. The purpose of this study is to analyze the accuracy of the TCRT5000 as a drop sensor, based on readings of the infusion pump monitoring system. This module consists of a TCRT5000 drop sensor module, comparator circuit, monostable circuit, stepper motor, L298N motor driver, and ATmega328 microcontroller. The droplets are detected by the TCRT 5000 sensor, then amplified by a comparator and monostable circuit, then the flow rate and remaining volume readings are generated by the ATmega328 microcontroller. Furthermore, this data is sent to the Personal Computer (PC) via wireless HC-11. The results of the flow rate module measurement show that the highest error value is 4% at the 30 ml/hour setting, and the lowest error value is 1% at the 60 ml/hour setting. While the results of the flow rate measurement using an Infuse Device Analyzer, the highest error value is 2,2% at the 30 ml/hour setting, and the lowest error value is 0,58% at the 100 ml/hour setting. This infusion pump monitoring is designed centrally to facilitate the nurse's task in monitoring the infusion dose accurately that is given to the patient.
有些医院仍采用人工输液的方式,医务人员直接观察液体滴下,然后用机械电阻(钳)控制滴下速率,这种方法的准确性显然还差得远。输液泵是一种医疗辅助设备,具有控制和保证给病人正确的输液剂量的功能。本研究的目的是根据输液泵监测系统的读数,分析TCRT5000作为液滴传感器的准确性。该模块由TCRT5000跌落传感器模块、比较器电路、单稳电路、步进电机、L298N电机驱动器和ATmega328微控制器组成。液滴由TCRT 5000传感器检测,然后由比较器和单稳电路放大,然后由ATmega328微控制器生成流速和剩余体积读数。此外,这些数据通过无线HC-11发送到个人电脑(PC)。流速模块测量结果表明,在30 ml/小时设置时,误差值最高为4%,在60 ml/小时设置时,误差值最低为1%。而使用inuse Device Analyzer测量流速的结果,在30 ml/小时设置时,最大误差值为2.2%,在100 ml/小时设置时,最小误差值为0.58%。这种输液泵监测是集中设计的,以方便护士准确监测给病人的输液剂量。

Energy is an important element in the continuity of human activities. Indonesia has the potential to produce 94.3GigaWatt of electricity in the hydropower sector, but only a few can be utilized, which is only 4.2GigaWatt [1]. This study aims to utilize renewable energy that has not been utilized optimally, especially in Indonesia. This study exploits the potential of water flow from the Coban Wonoasri River, Bangun Village, Munjungan District, Trenggalek Regency which has a low head but has a fairly heavy discharge. The basin cone for making vortex flow has a canal length of 1450mm, a canal width of 231.5mm, and a canal height of 500mm with a basin cone diameter of 560mm, a basin cone height of 700mm, and a water outlet diameter of 90mm. A vortex turbine with a diameter of 270mm and a height of 210mm with a total of 8 blades, a blade curvature of 30°, and a blade tilt of 22.5° was used for research on this low head river. The inlet notch variations that will be used are angles of 0°, 17.82°, 19.30°, and 19.98°. The inlet notch with a width of 0° and a discharge of 8.81l/s cannot produce turbine rotation because the vortex flow is not formed properly. Inlet notch with a width of 17.82° and 19.30° produces an average turbine speed of 157.2 rpm and 159.2 rpm. The variation of the inlet notch with a width of 19.98° produces the best turbine speed of 162.7 rpm with a flowrate of 7.72l/s.
能源是人类活动连续性的重要因素。印尼在水电领域有潜力生产94.3吉瓦的电力,但能被利用的很少,只有4.2吉瓦[1]。这项研究的目的是利用可再生能源,没有得到充分利用,特别是在印度尼西亚。本研究利用了Trenggalek县Munjungan区Bangun村Coban Wonoasri河的水流潜力,该河水头低,但流量相当大。制造涡流的盆锥,槽长1450mm,槽宽231.5mm,槽高500mm,盆锥直径560mm,盆锥高度700mm,出水口直径90mm。采用直径为270mm,高度为210mm的涡轮机,共8片叶片,叶片曲率为30°,叶片倾角为22.5°,对这条低水头河流进行了研究。将使用的进口缺口变化角为0°,17.82°,19.30°和19.98°。入口缺口宽度为0°,流量为8.81l/s,由于旋涡没有正确形成,无法产生涡轮旋转。宽度为17.82°和19.30°的进口缺口产生了157.2 rpm和159.2 rpm的平均涡轮速度。进气道缺口宽度为19.98°时,最佳涡轮转速为162.7 rpm,流量为7.72l/s。

Spectrophotometers generally use a halogen lamp as a light source that passes through a filter (wavelength) according to the material to be analyzed. This study aims to analyze the ability of the LED as a light source on a spectrophotometer. In this study, the authors have determined blood sugar parameters as the test material. So that the determination of the wavelength of the LED as a light source must be adjusted to the specifications of the wavelength in the reagent manual procedure used. In the BAV Greiner Glucose Reagent procedure, the allowable wavelength is between 500 - 570 nm with a cuvette thickness of 1 cm. Measured against the reagent blank by the endpoint method. From this reference, the author uses an LED light source with a wavelength of 530 nm, Epistar brand green. The module in this study consisted of a 530 nm LED lamp as a light source, then a lens was added to focus the light beam from the 530 nm LED. The author also adds a Slit / Aperture or it can be called a small hole so that the light passing through is focused at one point of the circle and is passed to the cuvette. The results of the absorption of light will be received by the light sensor (photoresistor) and the data is processed by Arduino and the results are displayed on the display. From the results of this study, the value ranges error from 1% to 3% when a comparative test is carried out with the Analyticon type Biolyzer100 spectrophotometer with 6 different samples and is repeated 5 times each. From these data, it is found that the LED with a wavelength of 530 nm is effective as a light source for checking blood sugar.
分光光度计通常使用卤素灯作为光源,根据要分析的材料通过滤光片(波长)。本研究旨在分析LED在分光光度计上作为光源的能力。在这项研究中,作者确定了血糖参数作为测试材料。因此,确定LED作为光源的波长必须调整到试剂手册程序中使用的波长规格。在BAV Greiner葡萄糖试剂程序中,允许波长在500 - 570nm之间,试管厚度为1cm。用终点法对试剂空白进行测量。从这个参考文献中,作者使用了波长为530nm的LED光源,Epistar品牌绿色。本研究的模块由530nm的LED灯作为光源,然后添加一个透镜来聚焦530nm LED发出的光束。作者还增加了一个狭缝/孔径,或者它可以被称为一个小孔,以便通过的光聚焦在圆的一点上,并通过试管。光的吸收结果将被光传感器(光敏电阻)接收,并由Arduino处理数据,结果显示在显示屏上。从本研究的结果来看,当使用Analyticon型Biolyzer100分光光度计对6种不同的样品进行比较测试时,每种样品重复5次,其值的误差范围为1%至3%。从这些数据中发现,波长为530纳米的LED作为检测血糖的光源是有效的。

The development of technology also affects human health, including body posture due to poor human position when using gadgets, both smartphones, and laptops. This study is design a tool that can measure the elevation of a person's neck angle equipped with electromyography, to help health workers, medical rehabilitation doctors to diagnose and provide treatment to patients with a bent head posture or forward head posture. In this research, an electromyography module is designed which consists of a series of instruments, a pre-amplifier circuit, a high pass filter, a low pass filter, and a dc offset regulator to be converted to digital so that it can be displayed on a laptop. In this study, the tapped muscle was the upper trapezius muscle using disposable electrodes. Meanwhile, to measure the angular elevation, the MPU 6050 sensor is used to measure the movement of the head forward. The frequency of the electromyography signal is 20-500 Hz. For software or display readings from this tool is Delphy. Meanwhile, the microcontroller used for ADC communication is Arduino Uno. From the research, it was found that the neck angle elevation gauge has a 0,597% error rate, for conditioning conducted on respondents, all respondents experienced a decrease in amplitude on the same frequency spectrum in the last ten minutes. Meanwhile, a drastic decrease occurred at the neck angle of 60°. Thus, it can be concluded that the forward position of the head affects the frequency spectrum of the neck muscles.

Malaria Parasite Detection using Efficient Neural Ensembles 基于高效神经系统的疟疾寄生虫检测
Pub Date : 2021-10-15 DOI: 10.35882/jeeemi.v3.i3.2
Saurav Mishra
Caused by the bite of the Anopheles mosquito infected with the parasite of genus Plasmodium, malaria has remained a major burden towards healthcare for years with an approximate 400,000 deaths reported globally every year. The traditional diagnosis process for malaria involves an examination of the blood smear slide under the microscope. This process is not only time consuming but also requires pathologists to be highly skilled in their work. Timely diagnosis and availability of robust diagnostic facilities and skilled laboratory technicians are very much vital to reduce the mortality rate. This study aims to build a robust system by applying deep learning techniques such as transfer learning and snapshot ensembling to automate the detection of the parasite in the thin blood smear images. All the models were evaluated against the following metrics - F1 score, Accuracy, Precision, Recall, Mathews Correlation Coefficient (MCC), Area Under the Receiver Operating Characteristics (AUC-ROC) and the Area under the Precision Recall curve (AUC-PR). The snapshot ensembling model created by combining the snapshots of the EfficientNet-B0 pre-trained model outperformed every other model achieving a f1 score - 99.37%, precision - 99.52% and recall - 99.23%. The results show the potential of  model ensembles which combine the predictive power of multiple weal models to create a single efficient model that is better equipped to handle the real world data. The GradCAM experiment displayed the gradient activation maps of the last convolution layer to visually explicate where and what a model sees in an image to classify them into a particular class. The models in this study correctly activate the stained parasitic region of interest in the thin blood smear images. Such visuals make the model more transparent, explainable, and trustworthy which are very much essential for deploying AI based models in the healthcare network.
疟疾是由感染了疟原虫属寄生虫的按蚊叮咬引起的,多年来一直是医疗保健的一个主要负担,据报告,全球每年约有40万人死亡。疟疾的传统诊断过程包括在显微镜下检查血液涂片。这个过程不仅耗时,而且要求病理学家在工作中具有很高的技能。及时诊断和提供强大的诊断设施和熟练的实验室技术人员对降低死亡率至关重要。本研究旨在通过应用迁移学习和快照集成等深度学习技术建立一个鲁棒系统,以自动检测薄血涂片图像中的寄生虫。所有模型均根据以下指标进行评估:F1评分、准确率、精密度、召回率、马修斯相关系数(MCC)、受试者工作特征下面积(AUC-ROC)和精确召回曲线下面积(AUC-PR)。通过结合EfficientNet-B0预训练模型的快照创建的快照集成模型优于所有其他模型,达到f1得分为99.37%,精度为99.52%,召回率为99.23%。结果显示了模型集成的潜力,它将多个福利模型的预测能力结合起来,创建一个更有效的模型,更好地处理现实世界的数据。GradCAM实验显示了最后一个卷积层的梯度激活图,以直观地说明模型在图像中看到的位置和内容,从而将它们分类到特定的类中。本研究中的模型正确地激活了薄血涂片图像中感兴趣的染色寄生区域。这样的视觉效果使模型更加透明、可解释和可信,这对于在医疗保健网络中部署基于AI的模型非常重要。

A Smart System to Ease Occurrence of Bedsores 减轻褥疮发生的智能系统
Pub Date : 2021-10-11 DOI: 10.35882/jeeemi.v3i3.6
Benjamin Kommey
The occurrence of bedsores in Ghanaian hospitals, elderly homes or care homes is especially high among patients or people who are incapacitated and cannot move or turn on their own, and who happen to remain in a particular posture for a very long time. Patients in coma, those operated on and for that matter in critical state, and patients confined to wheelchairs are primary examples. Constant pressure on some parts of the body leads to the occurrence of pressure sores or ulcers. This paper seeks to implement a Bedsore Easing System (BeSoSys) that integrate several embedded hardware components, a database and software to reduce the occurrence of bedsores. These embedded hardware components include the Bed Device Unit (BDU), the Pocket Device Unit (PDU), a pressure or weight sensor, a temperature sensor, and an inflation-deflation device. The BDU is fitted into the bed of the patient or on the surface of skin contact of the patient. The PDU is assigned to nurses or caretakers to serve as an alarm system for patient repositioning depending on situation. All activities in the Bedsore Easing System are logged into a database for future references. A bedridden patient exerts constant pressure on the bony protrusions of the body, and this causes bedsores. It was found out during the research that in Ghana, the nurses or caretakers used to turn and massage patients at some random time intervals as a way of preventing bedsores. This traditional way of turning and massaging patients is not only tedious but also ineffective. This paper seeks to provide easy, better, and effective solution to ease bedsores. The BeSoSys intends to prevent the occurrence of bedsores hence the alleviation of bedsore complications
在加纳的医院、老人院或护理院中,在病人或不能自主移动或转身、碰巧长时间保持特定姿势的人当中,褥疮的发病率尤其高。昏迷病人、手术病人和危重病人、坐轮椅的病人是主要的例子。对身体某些部位的持续压力会导致压疮或溃疡的发生。本文旨在实现一个褥疮缓解系统(BeSoSys),该系统集成了多个嵌入式硬件组件,数据库和软件,以减少褥疮的发生。这些嵌入式硬件组件包括床上设备单元(BDU)、口袋设备单元(PDU)、压力或重量传感器、温度传感器和充气-放气装置。BDU安装在患者的床上或与患者皮肤接触的表面。分配给护士或看护人员作为警报系统,根据情况对患者进行重新定位。褥疮缓解系统的所有活动都记录在数据库中,以备将来参考。卧床不起的病人对身体的骨突出物施加持续的压力,这就造成了褥疮。在研究中发现,在加纳,护士或看护者习惯在一些随机的时间间隔为病人翻身和按摩,作为一种预防褥疮的方法。这种传统的给病人翻身按摩的方法不仅繁琐而且无效。本文旨在提供简单,更好,有效的解决方案,以缓解褥疮。BeSoSys旨在防止褥疮的发生,从而减轻褥疮并发症

Health problems with cardiovascular system disorders are still ranked high, according to data from the WHO reported that there are about 31% of causes of death globally are cardiovascular diseases. The purpose of this study was to develop a 12 lead electrocardiograph with 2 displays and the HC-05 as a real-time transmitter of heart signal data. The electrocardiogram signal is obtained from the wiretapping by attaching the electrode cable to the Lead I, Lead II, Lead III, aVR, aVL, and aVF leads, then processed on IC AD620, HPF and LPF filters and non-inverting amplifiers and then processed using Arduino UNO for further display. in the form of a signal on the Delphi 7 application. The research method is to measure the heart signal on the ECG Simulator, by testing several BPMs, namely 30, 60, 120 and 240 on each lead. After testing the signal equation at the 0.5mV setting by calculating the error rate, the highest error value is obtained in lead I, lead aVL and aVF of 7.14% and the smallest error is 3.57% error in lead III. Then at the 1mV setting by calculating the error rate, the highest error value in lead aVL is 7.14% and the smallest error is 2.36%. at the 2mV setting by calculating the error rate, the highest error value is obtained in leads aVL and aVF of 5.71% and the smallest error is obtained by an error of 2.1% in lead II. the results of this study are implemented so that in the future an ECG examination can be carried out and then monitored remotely like a doctor's room because the data communication uses bluetooth.
根据世界卫生组织的数据,心血管系统疾病的健康问题仍然排名很高,全球约有31%的死亡原因是心血管疾病。本研究的目的是开发一种带有2个显示器的12导联心电图仪,并将HC-05作为心脏信号数据的实时发射器。通过将电极电缆连接到引线I、引线II、引线III、aVR、aVL和aVF引线上获得窃听后的心电图信号,然后在IC AD620、HPF和LPF滤波器以及非反相放大器上进行处理,然后使用Arduino UNO进行处理,进一步显示。在Delphi 7应用程序上以信号的形式。研究方法是在心电模拟器上测量心电信号,在每条导联上分别测试30、60、120和240个bpm。通过计算错误率对0.5mV设定下的信号方程进行测试,得出引线I、引线aVL和aVF的误差值最大,为7.14%,引线III的误差最小,为3.57%。通过计算错误率,在1mV设置下,导联aVL的最大误差值为7.14%,最小误差值为2.36%。通过计算错误率,在2mV设置下,导联aVL和aVF的误差值最大,为5.71%,导联II的误差最小,为2.1%。由于数据通信采用蓝牙技术,因此本研究的结果可以实现,以便将来进行心电图检查,然后像医生的房间一样远程监控。

Swarm intelligence (SI), an important aspect of artificial intelligence, is increasingly gaining popularity as more and more high-complexity challenges necessitate solutions that are sub-optimal but still feasible in a fair amount of time. Artificial intelligence that mimics the collective behavior of a group of animals is known as swarm intelligence. Attempting to survive. It is primarily influenced by biological systems. The main aim of our article is to find out more about the guiding principle, classify possible implementation areas, and include a thorough analysis of several SI algorithms. Swarms can be observed in ant colonies, fish schools, bird flocks, among other fields. During this article, we will look at some Swarm instances and their behavior. We see many Swarm Intelligence systems, like Ant colony Optimization, which explains ant activity, nature, and how they conquer challenges; in birds, we see Particle Swarm Optimization is a swarm intelligence-based optimization technique, and how the locations must be positioned based on the three concepts. The Bee Colony Optimization follows, and explores the behavior of bees, their relationships, as well as movement and how they work in a swarm. This paper explores some of the methods and algorithms.
