The aim of this paper is to find a relation between HRV parameters of ECG and stressful driving situation in the real road through various tests. First, we gave a stress to the subject by increasing the driving speed using driving simulator in the laboratory. Second, the subject drove the vehicle on the real road. Through let him drove in the busy narrow street, we evoked stress. ECG and PPG signal was recorded from steering wheel and back cushion each unconsciously. The driving experiment with simulator was not suitable to reproduce actual traffic condition because the adaptation was occurred. On the other hand, in real driving test, the results show that the heart rate is increase, and SDNN, RMSSD, pNN50 were decreased. The heart rate is the strongest indicator and other parameters tend to be changed depend on a personal. The blood pressure had no significant changes. Our results show the good possibility of that the time parameters of the HRV could be used as an instantaneous stress indicator.

Personal robots and robot technology (RT)- based assistive devices are expected to play a major role in Japan's elderly-dominated society, both for joint activities with their human partners and for participation in community life. These new devices should be capable of smooth and natural adaptation and interaction with their human partners and the environment, should be able to communicate naturally with humans, and should never have a negative effect on their human partners, neither physical nor emotional. To achieve this smooth and natural integration between humans and robots, we need first to investigate and clarify how these interactions are carried out. Therefore, we developed the portable bioinstrumentation system WB-2 (Waseda bioinstrumentation system No.2), which can measure the movements of the head, the arms, and the hands (position, velocity, and acceleration), as well as several physiological parameters (electrical activity of the heart respiration, perspiration, pulse wave, and so on), to objectively measure and understand the physical and physiological effects of the interaction between robots and humans. In this paper we present our development of the Inertial Measurement Unit, which is at the heart of our new motion-capture system that replaces the system used in the Waseda bioinstrumentation system No.1 refined (WB-1R). Some preliminary results of experiments with the unit are also presented and analyzed.

Recent educational theory emphasizes the importance of considering identity processes in studying learning and development. In engineering education, identity has been cited as central in student development, for example, as a key factor in retention of students in the discipline, in particular with regard to underrepresented groups. This paper adopts a social theory of identity to examine how dynamics of "sponsorship" relates to students' decisions of whether to remain in or switch out of engineering. This paper draws on longitudinal case studies of two students to examine the relationship between students' interests and their decisions to persist in or leave their major. We argue that students' interests become differentially identified as "intrinsic" or "extrinsic" to engineering through the work of powerful sponsors within the discipline. We argue further that a view of identity as socially produced is necessary in order to avoid taking for granted crucial aspects of disciplinary practices of identifying engineers, and in particular ways in which certain kinds of interests might be sponsored over and above others. © American Society for engineering Education, 2007.

Molecular wire construction using DNA-directed self-assembly of multi-walled carbon nanotubes (MWNTs) has been attempted. MWNTs were selected owing to their exceptional electrical and structural properties. DNA, which possesses specific molecular recognition properties, served as the engine for the assembly. Non-crosshybridizing (NCH) sequences were designed to impart specificity and high throughput reaction. Stepwise manufacturing of the wire was accomplished by first functionalizing the NCH 20 base pair single-stranded sequences to the tips of MWNT using amide linkage. The adducts were then utilized to self-assemble 1D nanotube wire through DNA hybridization reactions between two complementary ssDNAs functionalized to the MWNT tips. TEM, epi-fluorescent microscopy and AFM analyses showed successful assemblies of micrometer-scale 1D MWNT-DNA wires, ranging from 2.7-20 mum. The results demonstrate great potentials of the DNA-guided self-assembly process, which would provide an uncomplicated, versatile and inexpensive way to manufacture micrometer-scale molecular wires.

This paper reports the design and fabrication of a biosensor based on aligned single wall carbon nanotubes (SWCNTs) with integrated single-strand DNAs (ssDNA). This ultra-sensitive biosensor provides label-free real-time electronic detection of DNA hybridization between surface-immobilized ssDNA and target ssDNA. Hybridization kinetics between complementary and target ssDNA nucleotide base pairs result in a local charge generation between base pairs that is injected into the SWCNTs resulting in a detectable change in SWCNT electrical conductance. This conductance change is amplified electrically through the integration of the functionalized SWCNTs as the semi-conductive channel in a silicon-silicon oxide based field effect transistor (FET). Based on previous Langmuir DNA kinetics calculations, the projected sensitivity level of the SWCNT-DNA sensor is considerably higher than traditional fluorescent and hybridization assays.

Minimally invasive surgery (MIS) has become very common in recent years, thanks to the many advantages it provides for patients. Since it is difficult for surgeons to learn and master this technique, several training methods and metrics have been proposed, both to improve the surgeon's abilities and also to assess his/her skills. This paper presents the use of the WB-1R (Waseda bioinstrumentation system no.1 refined), which was developed at Waseda University, Tokyo, to investigate and analyze a surgeon's movements and performance. Specifically, the system can measure the movements of the head, the arms, and the hands, as well as several physiological parameters. In this paper we present our experiment to evaluate a surgeon's ability to handle surgical instruments and his/her depth perception using a laparoscopic view. Our preliminary analysis of a subset of the acquired data (i.e. comfort of the subjects; the amount of time it took o complete each exercise; and respiration) clearly shows that the expert surgeon and the group of medical students perform very differently. Therefore, WB-1R (or, better, a newer version tailored specifically for use in the operating room) could provide important additional information to help assess the experience and performance of surgeons, thus leading to the development of a global performance index for surgeons during MIS. These analyses and modeling, moreover, are an important step towards the automatization and the robotic assistance of the surgical gesture.

A lumped parameter model of the cardiovascular system (CVS) and its interaction with an implantable rotary blood pump (iRBP) is presented-^sThe CVS model consists of the heart, the systemic and the pulmonary circulations. The pump model is made up of three differential equations, i.e. the motor equation, the torque equation and the hydraulic equation. Qualitative comparison with data from ex vivo porcine experiments suggests that the model is able to simulate different physiologically significant pumping states with varying pump speed set points. The combined CVS-iRBP model is suitable for use as a tool for investigating changes in the circulatory system parameters in the presence of the pump, and for testing control algorithms.

A dual-modality SPECT-CT system for dedicated 3D breast cancer imaging is under development. Independent dedicated SPECT and CT imaging systems have been integrated onto a single gantry for uncompressed breast imaging. This study examines challenges and tradeoffs involved in integrating the acquisition procedures of two independent imaging systems into a single imaging protocol. The physical limitation of the rotating CT tube beneath the custom patient bed currently provides only a 294 degree scan with the bed low enough for the breast to be in the cone-beam CT field-of-view. The directly coupled SPECT system is therefore also limited if the scans are to be taken simultaneously or in an interleaved fashion. Thus, geometric phantoms are imaged to characterize image degradations due to reduced projection angles for both modalities. Two different acquisitions were performed: one with the central ray of the CT cone-beam aligned with the system's center of rotation and one offset from the center of rotation by 5cm. Various sized activity-filled lesions in an anthropomorphic breast phantom were imaged, first with uniform aqueous background activity and then with added acrylic pieces to simulate a non-uniform background. Interleaving the SPECT and CT acquisitions into a single scan was also investigated. Iterative reconstruction algorithms are used to reconstruct the data, and the SPECT and CT images are co-registered. Both the cold rod and breast data indicate that removing 75° of SPECT azimuthal data does not significantly reduce image quality. CT images were also minimally affected if the cone-beam is centrally aligned with the center of rotation, but degraded with the laterally offset cone-beam setup. In the course of these experiments, the patient bed was reconfigured with a larger central hole covered with flexible neoprene, gaining the ability to rotate completely around the breast and dramatically improving CT projection views through the chest wall.
