In this study, twelve heavy metals in black soybeans, pressed black soybean oils (BSOs), and Taiwanese commercial edible oils were determined by inductively coupled plasma-mass spectrometry (ICP-MS). The main factors affecting heavy metal contents in edible oils were the pressing and refining processes, while the origins of raw materials had minor effects on the heavy metal contents of oil crops. Different heavy metals had different migration rates between the raw materials of black soybeans and BSOs. Analytical results of heavy metal contents in commercial edible oils showed that levels in refined oils were significantly lower than those in unrefined oils. Distribution trends of heavy metals in edible oils were primarily determined by the type of raw material. A principal component analysis and cluster analysis were performed on 19 kinds of edible oils to obtain the distribution characteristics of heavy metals. Among them, Cd, Ba, Fe, Pb, and Co were the main variables, playing major roles in heavy metal levels of edible oils. The present study revealed the influencing factors and distribution characteristics of heavy metal contents in edible oils and assessed the health risks of heavy metal exposures via Taiwanese commercial edible oils. © 2023, The Authors.

In recent years, with the increase in the number of dogs, paralysis of the lower limbs due to herniated discs in dogs has become a problem. There is no fundamental cure for this condition, and the main treatment is physical therapy. Usually, these dogs need physical therapy with a physical therapist every day, but it’s not realistic. Therefore, it is required that the owner be effective rehabilitation at home. However, quantitative evaluation methods have not been established for physiotherapy because physiotherapy is performed by veterinarians based on their experience. In this paper, we proposes a musculoskeletal model of the dog’s lower limb to analyze the dynamics of rehabilitation movements and confirm its validity by comparing the muscular activity obtained from the model with the measured EMG data. Using proposed model, we performed a simulation experiment to discuss the relationship between the timing of the input force and muscular activity by changing the timing of the input force. From the data obtained in the experiment, we investigated the relationship between the timing of the input force and the muscular activity and clarify how to input a support force for the physical therapy.

In recent years, dogs are commonly kept indoors. Dogs, as animals that inherently walk on grippy outdoor ground, sometimes slip when walking on indoor wooden flooring, which can lead to injuries and arthritis. We have therefore developed a method to increase the coefficient of friction by applying a special coating to the wooden flooring to make it less slippery when the dog walks on it. The objective of this paper is to investigate whether the friction coefficient of the flooring can prevent dogs’ lower limbs from slipping when they walk, and to analyze the effects of lower limb slippage on the musculoskeletal system of dogs when they walk on the flooring. In the measurement experiment, walking movements were performed with and without paint coating on the wooden flooring, the test dogs were applied to a 3D musculoskeletal system simulation software model, and the amount of muscular force exerted was calculated through a simulation experiment with measured data. In addition, the floor reaction forces of the lower limbs during walking were measured and compared, and the effects of the friction coefficient of the floor environment on walking behavior were discussed.

The purpose of this research is to develop an omni-directional low-floor mobility. The mobile platform and the interface of the mobility have already developed. The height of the mobile platform is 37 mm from road surface to the boarding floor. Omni-directional movement is realized by using four mecanum wheels. The operation interface is consisted of eight load cells. The operation for omni-directional movement is realized by using load distribution information obtained from eight load cells. However, movement of the mobility tends to oscillate due to unintended body movement caused by inertia of the platform. In order to solve this problem, this research proposes control method by introducing not only an inverted pendulum model but also a human postural control model. In this paper, we focus on forward backward movement. First, the estimation method of human body inclination using load distribution on the boarding surface is proposed. Next, a controller of the mobility is proposed by introducing the human postural control model, and is simulated. Finally, the effectiveness of the controller including the human postural control model is shown by comparing with the controller not including the human postural control model which is validated by preliminary simulation.

The purpose of this research is to develop the wheelchair system for hemiplegic users. The proposed system is configured by the front wheel with active steering and hand rim for detecting user's driving force. The user's operational intention is distinguished by the sign and amplitude of force along the rotational axis of the hand rim. The steering angle of the front wheel is controlled by an actuator based on extracted intention from the hand rim. By proposed system, user can operate the wheelchair by using only single side hand rim. In particular, in this paper, we evaluate the designed hand rim by conducting some experiments. © 2019 IEEE.

This paper proposes the ungrounded force display using the grooved cam. Using the human illusion, the user can feel the force in the one direction when they use proposed device. It is mainly configured the cam and the slider. The slider follows the cam and moves translational movement. In this paper, we create the new prototype which solving the problems that emerged from the previous prototype. We evaluate the device using the two experiments. One is the subjective evaluation. Second one is the force presentation from the new prototype as the quantitative evaluation. We could solve problems of previous prototype by changing the cam type from plate to groove and blushless motor, and the new one produce the force more clearly than the previous prototype. © 2019 IEEE.

The conventional robot arms applied in various fields are demanded to have high force output, high accuracy, high efficiency. But they are seldom applied in human life, because of large weight, rigidity, hazards to people caused by collisions. Therefore the soft robotic arm that is stretchable, light weight, softness without possible of hazards, and high precision control is suitable to deploy in human life. Thus the purpose of this research is to develop the soft robotic arm by using antagonistic pneumatic driven system. In order to realize this concept, the joint activation mechanism is the key component. This study focuses on the angle control of the joint. In this paper, the robot arm made by polyethylene is proposed. Air bags made of polyethylene inside the joint achieve antagonistic driven states. Helical tube made of polyethylene is adhered joint outside for realizing rigidity. It is characterized that control rigidity is realized by controlling the pressure in the helical tube and joint angle is preciously controlled in two degree of freedom by controlling pressure in the air bags. Furthermore, the joint angle can be controlled by controlling the air pressures in the air bags using stretch sensor measuring joint angle. The experimental result confirmed that the driving concept of the joint was well functioned, and the joint angle control was realized by feedback control. © 2019 IEEE.

This paper proposes a novel standing assistance robot, which considers the posture tolerance of its user. In previous studies, conventional assistive robots did not require patients to use their own physical strength to stand, which leads to decreased strength in the elderly. Therefore, an assistive robot that allows patients to maximally use the physical strength they possess is required. To realize this objective, it is important that a robot assists patients according to their body movement and by their intentions. However, in previous studies, general assistive robots helped patients by using a fixed motion reference pathway in spite of their original intention, and as a result, these robots failed to use the physical strength of the patients. In our previous study, we investigated the posture tolerance during a standing motion. In this tolerance, patients could stand by own muscle strength with stable posture. Thus, as the next step, this paper proposes assistance force control scheme which considers the investigated posture tolerance. Our robot generated assistance force, which lead the voluntary movement with their remaining physical strength within investigated range, by combining position control and force control. A prototype assistive robot, based on the proposed idea was fabricated to help patients stand up safely using the maximum of their remaining physical strength.

The purpose of this research is to develop the electric assist wheelchair system for hemiplegic users. The proposed system is able to move in any direction by operating only one hand rim on one side. The hand rim can detect the user's operational intention by measuring contacting force and status of grasp and its style. The proposed system enables straight ahead, go back, gradual turn, pivot turn and stop based on the force being applied to the hand rim, whether the hand rim is grasped or not, and rotational speed of the hand rim. After the user operates the hand rim and releases it, the moving mode shifts to the deceleration mode. In the deceleration mode, the pseudo inertia deceleration is reproduced by motors. In this paper, we focus on the proposal of the system and the inertia deceleration by controlling motors, and verify how much it can reproduce in the outdoor environment.
