Breast Cancer is the most dominant cause of mortality in women. Early diagnosis and treatment of the disease can stop the spreading of cancer in the breast. Due to this nature of the problem, accurate prediction is the most important measure of the predictive model. This paper proposes the comparison of ensemble learning techniques in predicting breast cancer. This approach is widely used for performance improvement of the predictive task. The ensembles algorithms used in this research study are AdaBoost, Random Forest, and XGBoost. The result indicates that the random forest is the best predictive model for this dataset. The model has the following performance measure, accuracy 97%, sensitivity 96%, and specificity 96%. The experiment is executed using scikit-learn machine learning library. With this high level of accuracy offered by the model, the model can help the doctor to identify whether the patient has malignant or benign tumor cancer cells with high precision.

Study in universities can be perceived as a positive challenge. However, pressures to meet academics standard, life transitions, relation with friends, and time management are potentials to boost depression, anxiety, and stress. Furthermore, students with psychological health problems were reported having worse quality of life. Therefore, it is beneficial for students to understand their conditions in order to maintain their psychological health. The ability to assess the psychological condition using tools that can be selfoperated may assist a self-help monitoring and enhancing knowledge about their conditions. This research aims to develop a mobile, fast response, and interactive measurement of psychological condition regarding depression, anxiety, and stress status application in android based smartphones.

Intensive Care Unit (ICU) is a hospital unit that has an important role in restoring life-threatening patients condition. Predicting the patient's outcome after discharge from the ICU is necessary. The predicted outcome will determine the best medication for them. The paper will determine the ability of heart rate variability (HRV) parameters from multifractal detrended fluctuation analysis method to predict the short-term outcome of patient in ICU with sepsis condition. Data was obtained from MIMIC III Medical-ICU database. Only patients with sepsis condition is used in this study to reduce disease related influence in the study. Total 206 patients data were collected. It consists of 134 survivors and 72 non-survivors patients data. ECG recordings were obtained prior ICU disenrollment. First fifteen minutes recording were extracted into HRV time series. Then multifractal detrended fluctuation analysis were carried out to the time series of each patients. Along with the mentioned method, linear (time-frequency) and other nonlinear HRV measures were also calculated for comparison. Statistical significance is used to measure how the parameters perform to differentiate the outcome difference. The results shows that mean α from MF-DFA parameters can predict patients’ short-term outcome while the available linear and non-linear HRV analysis cannot.
重症监护室(ICU)是一种医院单位，在恢复危及生命的病人的病情方面起着重要作用。预测患者从ICU出院后的预后是必要的。预测的结果将决定对他们最好的药物。本文将利用多重分形无趋势波动分析法确定心率变异性(HRV)参数对ICU脓毒症患者短期预后的预测能力。数据来自MIMIC III Medical-ICU数据库。本研究仅使用脓毒症患者，以减少疾病对研究的影响。共收集206例患者资料。它包括134名幸存者和72名非幸存者患者的数据。在ICU退组前获得心电图记录。前15分钟的录音被提取到HRV时间序列中。然后对每个患者的时间序列进行多重分形去趋势波动分析。根据上述方法，还计算了线性(时频)和其他非线性HRV测量值进行比较。统计显著性用于衡量参数如何区分结果差异。结果表明，MF-DFA参数的平均α值可以预测患者的短期预后，而现有的线性和非线性HRV分析不能预测患者的短期预后。

At present, research on myoelectric hands is growing throughout the world. Some aspects of the bionic hand that are widely researched are the mechanism of the finger, actuator, and power consumption. The mechanism of fingers in many scientific articles examines how the motion and function of the bionic fingers / robotic hands approach normal motion and function of the human finger. There are three mechanism systems commonly found in both scientific articles and products on the market, namely springs, links, and gears. Most existing finger mechanisms simplify the function of fingers into two joints, MCP and PIP, while joint DIPs are made rigid and form a certain angle. This paper presents MCP and PIP angle instrumentation methods by measuring the strokes of linear actuators and the power consumed by the actuator. The MCP and PIP angles are acquired with the camera and then pass through the four-point color tracking algorithm in metacarpal, MCP joints, PIP joints, and joint DIPs. Tracking is conducted with computer vision using MATLAB-Simulink. Tracking is performed on myoelectric fingers and compared to normal human fingers when grasping. Linear actuator has a stroke length of 20 mm. The position of the linear actuator stroke is obtained by using feedback from the linear potentiometer contained in the linear actuator. Actuator strokes and flowing electric currents are measured using a microcontroller and sent using serial transmit to the computer for data acquisition systems.

The use of Computer Aided Design (CAD) / Computer Aided Manufacturing (CAM) to produce biomedical devices has recently become more interesting because of environmental benefits and the fact that it has been done using computer simulations. However, CAD / CAM operating costs are a major obstacle to product commercialization. High specification computers are used as a raw material for design, customizing the processes of transferring continuous digital images and small-size and high-quality manufacturing tools are major options to reduce the cost of CAD / CAM operations. The most widely used method is to optimize how CAD and CAM devices work through an algorithm. This optimization will contribute to the rapid development of the ability to produce better products and reduce operating costs. The case study to be conducted is the development of CAD / CAM optimization over the past years (2013, 2018) towards the production of biomedical devices.

One of the problem of the after stroke walking training is fear of fall. Fear of falling is significantly corresponded to earlier falls and poor physical function. Lower high frequency (HF) power which is measured from heart rate variability has correlation to the stress, panic, anxiety, or worry. This study proposed a method to detect fear of falling using Photoplethysmography (PPG). The PPG signal is acquired using Arduino. The acquired signal is then processed using several step including trend removal, band frequency filtering, band power estimation, and decision system. Trend removal is conducted using moving average while the band frequency filtering is conducted using second order Butterworth band pass filter. The 2 section video is used to induce relax and fear of falling on the subject feeling which is used as the class on decision system. The output of the decision system is then compared to the class and the MAPE is computed. The result shows that the system can yield MAPE 16.63% which is can be categorized as a good result.

Upper limb disabilities become a concern to Indonesia. There are many prosthetic hand products from other countries, but they do not fit to Indonesian citizen, neither for the price nor the size. Because of it, Diponegoro University developed a prosthetic hand to solve the problem that currently faced by the Indonesian citizen. This prosthetic hand was expected to be a prosthetic hand that fit, either for the price or the size, with Indonesian citizen. Design safety becomes the concern of the development of prosthetic hand, and this paper investigates the reliability of the Middle finger of the prosthetic hand under the hook load. The result is the upper part experienced maximum stress at the value 54.524MPa and the lower part experienced maximum stress at the value 29.472 MPa. The maximum stress that occurs on the Middle finger of the prosthetic hand was still under the yield stress of material. With the safety factor about 1.28 and 2.37 for upper part and lower part, respectively, it can be considered that the prosthetic hand that has been developed in Diponegoro University was safe to use on hook position

Autism spectrum disorder (ASD) is a developmental disorder that related to brain development, affecting communication and behavior. Hallmarks of children with ASD are, they are not interested in communicating with other people and they find it really hard to focus on something they are not interested. Children with ASD need to learn some skills in order to increase their independence, including social skills, life skills, and focus. Some research studies have found that virtual reality (VR) is an effective tool for treatment in healthcare. In order to increase skills of children with ASD, we developed a system, based on VR and Leap Motion. We developed a game platform aiming to attract children with ASD to train their focus by placing balls with different colors in the box according to the ball’s color, and increasing their social skills by training them how react with social situations and virtual people around them. Our design has been tested and it showed well running interface. Participants in this game had three sessions of training and they were engaged with the game environment and they were able to follow the game scenario well for focus training, signs learning, and eye gazing learning. Their accuracies for all games were increased. The accuracy increase was about 11.16% for Game for Subject Focus, 16.6% for game for Focus with Distraction game, and subjects could interpret the arrows better by reaching each destination 2 seconds faster on each training session. The accuracy of Eye Gazing game was 75% for each training session.

The value of smart medical devices, including heart rate monitors, is forecasted by U.S. Smart Medical Devices to be increased yearly until year 2025. Smartphones play an important role in the healthcare industry, thus, the increase in smartphone usage is in parallel with the rising demand for wireless and smartphone-compatible medical devices. This in turn promotes awareness and focus on health and fitness, and demand-led growth for home usage. There were a few researches related to the methods used in the fabrication of flexible circuits such as screen printing, inkjet printing and direct transfer methods. On top of that, different flexible substrate materials such as paper, plastic (such as Polyethylene terephthalate (PET)), Kapton and textile-fabric were used by researchers to achieve their study objectives. Each method and material used in the previous studies were reviewed to address critical points such as to emphasize the adhesion property of materials as it may affect the quality and reliability of the flexible circuit during and after fabrication process. Thus, the focus of this study is to review a wireless ECG monitoring device which is compact, flexible, and equipped with wireless communication technology.
