According to the causes of death for people in 2018 provided by the Ministry of Health and Welfare in Taiwan (R.O.C), breast cancer and oral cancers rank 4th and 5th respectively among the top 10 cancer death rates. In order to avoid affecting the appearance or basic function of the defect site after the tumor resection operation, free skin flap surgery have to be performed. As the success rate of the surgery is currently around 97%, there are still 3% failures. Although the probability of failure is relatively low, once the flap becomes necrotic, one or two larger operations have to be performed for 7 to 8 hours. Therefore, monitoring after free skin flap transplantation to avoid skin flap necrosis is important. The monitoring of free flaps often relies on the experience of medical staff or professional equipment, and it is difficult to find problems in time. In addition, if the medical staff is inexperienced, it is easy to misjudge. This study cooperated with Tzu Chi Hospital in Hualien, Taiwan to provide a non-contact image analysis of heart rate as a method to decide whether the flap is necrotic, which can avoid infection caused by contact with the flap. The Difference-driven Weight-Setting algorithm based on the principle of Photoplethysmography (PPG) is used to analyze the signal to obtain the heart rate. The low time complexity of our algorithm shows the feasibility to utilize embedded systems for measurement. The experimental samples were collected from 36 cases after free skin flap surgery, and the heart rate measured by electrocardiograph (ECG) was compared with the heart rate calculated via the image with our proposed mechanisms. The initial analysis of the image is divided into two kinds of image quality: 1080p (1920 × 1080 pixels) with an accuracy rate of 71% and 720p (1280 × 720 pixels) with an accuracy rate of 36%, lower than expected. In the study, the factors affecting the measurement were investigated and improved. Further analysis of the stable image recorded at 720p was subsequently performed. The accuracy rate had been improved to 73% and the measurement time had also been substantially reduced by 36%.

In this paper, a modeling methodology for a continuous scanning probe of Micro-CMM inspired by the Kirigami structure was investigated. The displacement of the probe and the stress of the structure were computed by using the finite element method of Ansys software as the input parameter of the grey relation analysis to optimize the geometry parameter of the structure such as the thickness of the flexure sheet, the width of the flexure hinge, and the length of the flexure hinge. The thickness of the flexure sheet was 0.3 mm, the width of the flexure hinge was 1.5 mm, the length of the flexure hinge was 3 mm, which lead to the highest displacement of the probe. The contribution and the interaction of the thickness factor to the remaining elements are remarkable. The displacement of the probe can be reached at 4.546 mm.

This article investigates the quadrature voltage-controlled oscillator (QVCO) by using the loop closed-ring inductor and merging the excellent efficiency of class-C oscillator to the complementary PMOS-NMOS topology. Designed from TSMC 0.18 μm 1P6M CMOS processing, the presented folded-cascode mixer exhibits a high conversion gain, a maximum input P1dB of -12 to -16.7 dBm, IIP3 of -4.5 to -7.2 dBm, and LO to RF isolation of about 33.8 dB at VDD=1.5 V, respectively. The proposed QVCO works during 6.69 and 7 GHz at overall power dissipation is 7.59 mW. Experimental of phase noise and evaluated figure of merit (FOM) of the promoted 6.69 GHz QVCO are -113.56 dBc / Hz at 1 MHz frequency offset and -181.2 dBc/ Hz, respectively.

In this study, PEDOT:PSS conductive polymer printed flexible humidity sensor has been designed and fabricated to sense human respiration monitoring. PEDOT:PSS with conductive ink specifically formulated in our study, was printed on polyamide-based taffeta label fabric by an inkjet printing method. The sensitivity of the printed humidity sensor has been tested under different humidity levels inside a humidity chamber. Then, the sensor has been integrated into a face mask in order to evaluate the respiration monitoring of a user who wears the face mask in a real environment. The sensing capability of the wearable sensor and its response against respiration monitoring was evaluated under various breathing conditions such as fast and deep breathing, differentiating nose and mouth breathing. Owing to its flexible structure and printability onto textile, the wearable printed humidity sensor has the potential to be used for healthcare applications particularly for capturing user biomedical data.

According to the data from the seventh census, the proportion of the elderly population and the total dependency coefficient in China have increased significantly compared with that of the sixth census. The fertility situation is grim. The desire to procreate is the premise of procreation. The research on the influence of unmarried women of childbearing age on fertility intention is helpful to predict the change of fertility behavior and fertility trend. The paper applies the Bayesian network model to explore the influencing process of unmarried women's fertility intention and form the influence paths. Objective and social factors are considered as input variables, and fertility intention is taken as output variables in the network. Based on the data obtained from the National Social Science Fund project survey, the causal relationship and influence path between input variables and fertility intention are established. Social factors are considered to be the fertility tradition of unmarried women's environment and the attitude of people around them towards fertility intention. Therefore, this may be beyond the framework of cost-utility analysis. It is concluded that social factors will have an impact on unmarried fertility intention, and there is a complex relationship among them. The marriage intention affects the fertility intention, and it is affected by the personal income, which has a direct impact on the fertility intention. Besides, it is found that unmarried women's age, household registration type, educational background, and current residence had little influence on their fertility intention. It is noteworthy that this is the first attempt to choose the Bayesian network model to study fertility intention. The path between realistic factors and subjective perception of fertility desire needs further research.

Multi-access edge computing (MEC) is considered a promising technology to facilitate mission-critical vehicular applications, such as automatic driving, path-planning, and navigation. By offloading delay-sensitive or computation-intensive tasks from vehicles to MEC servers (MECSs), edge computing significantly enhances the computing capacity of vehicles with limited computing resources. However, MECSs may have uneven loads as vehicles are not evenly distributed across MEC systems and vehicles do not offload their tasks evenly. As a result, those offloaded tasks have high latency or be blocked. In addition, service interruption would happen frequently due to task migration caused by the high mobility. Due to the high mobility of vehicles and load dynamics at MECSs, computation tasks can migrate simultaneously to a particular MECS or migrate to a heavily congested MECS. Therefore, it is challenging to determine the migration decision, i.e., whether/where to migrate, among MECSs. In conventional methods, computation tasks are fully migrated to the MECS corresponding to the vehicle’s trajectory. By contrast, in this study, tasks are migrated partially or fully to other MECSs in the collaborative edge computing system. To reduce the task execution latency and improve the system throughput, the proposed method selects a MECS that optimizes load balancing among MECSs and partitions the task to migrate for the MECS. Through simulations, compared with the conventional methods, the proposed method can increase the satisfaction of quality of service (QoS) requirements and MEC system throughput by optimizing the load balancing and task partitioning.

The transplanting of seedlings is a fundamental task in industrial nurseries, and it is applied fundamentally in the process of quality control of the seedlings. Seedling quality control requires experienced operators to more accurately determine the quality of each seedling without the specialized human resources and affecting productivity. In this work, the design, simulation, and implementation of an electric multi-gripper system (three grippers) for artichoke seedlings transplantation is presented. A Cartesian robot is coupled as its end effector. The functional needs are identified and the conceptual, configuration and detail design is carried out for the mechanical and electronic subsystems. Also, an intelligent control strategy is developed to control the movements using optimal control and to communicate with a Cartesian robot in a master-slave framework. After extensive tests, the gripper performance is analyzed and results showed an improvement over existing grippers for transplanting. The results were a 100 % in the transplanting success rate of grasping and releasing seedlings in the tray cavities and only 2.94 % in the transplanting damage rate (mostly in leaves).

The synthesis of NGQDs was carried out via a microwave-assisted hydrothermal method where citric acid and urea were used as carbon and nitrogen sources, respectively. Uniformly distributed and spherical NGQDs were achieved after a 4 minutes reaction time and these dots were further loaded onto PANI/PAN to produce NGQDs/PANI/PAN composite via in-situ polymerization and electrospinning. Optimized electrospun composite fibers were characterized and later used for alcohol vapor sensing.
