The purpose of this study was to investigate influential factors for women who decided to participate in the women-only fitness club, Curves, with a qualitative research method. The qualitative data was collected with the semi-structured interview and analyzed based on the grounded theory approach using the concepts of self-presentation and the sport/exercise identity theory. The results indicated that there were five influential factors for interviewees to participate in Curves, such as 1) fears of men's eyes toward them in a mixed fitness club, 2) disgust for sweaty smell and body odor of men in a mixed fitness club, 3) the image incongruity between them and typical participants' of mixed fitness club, 4) the all fixed exercise program in Curves, and 5) the necessary time of the exercise program, less than 30 minutes, in Curves. The theoretical and practical implications of these findings are discussed.

The hostage case that occurred at the Japanese Ambassador's official residence in Peru in December 1996 and lasted for 127 days was so sensational that it occupied considerable space in Japanese newspapers for many days. The positive aspect of this phenomenon was contributing to newspaper readers' accumulation of knowledge about Peru. However, we should pay attention to the fact that the newspaper reports related to this issue were not necessarily enough to provide an objective regional understanding of Peru. This paper discusses the image formation of Peru through the Japanese regional newspaper reports on the extraordinary case which took place in Peru.

In the GAMMA 10 tandem mirror, the typical electron density is comparable to that of the peripheral plasma of torus-type fusion devices. Therefore, an effective method to increase Thomson scattering (TS) signals is required in order to improve signal quality. In GAMMA 10, the yttrium-aluminum-garnet (YAG)-TS system comprises a laser, incident optics, light collection optics, signal detection electronics, and a data recording system. We have been developing a multi-pass TS method for a polarization-based system based on the GAMMA 10 YAG TS. To evaluate the effectiveness of the polarization-based configuration, the multi-pass system was installed in the GAMMA 10 YAG-TS system, which is capable of double-pass scattering. We carried out a Rayleigh scattering experiment and applied this double-pass scattering system to the GAMMA 10 plasma. The integrated scattering signal was made about twice as large by the double-pass system.

Magnetic and magnetotransport properties of pyromellitic dianhydride-4,4′-oxydianiline polyimide-Co granular thin films prepared by vapor deposition polymerization are investigated. The prepared sample is composed of Co particles with diameters of 2–3 nm homogeneously dispersed in a denatured polyimide matrix. The temperature dependence of the resistivity closely follows the T−1/2 law, suggesting that the dominant conduction mechanism is tunneling between metallic granules embedded in the insulating polyimide matrix. The magnetoresistances at 300 and 90 K are 2.6% and 3.0%, respectively. The results indicate that polyimide is a promising material for organic spintronics.

A new method for determining the electron density of a thin plasma by means of Fabry-Pérot interferometry is proposed. The interferometer consists of two plasma layers and dielectric material surrounded by two plasma layers. The transmittance of electromagnetic waves across the interferometer is calculated, and Fabry-Pérot resonances are demonstrated. It is shown that the electron density can be determined from the measurement of the Fabry-Pérot resonance frequencies. This method can also be applied to the measurement of conduction electron density in semiconductor films.

An MRI pulse programmer has been developed using a single-chip microcontroller (ADμC7026). The microcontroller includes all the components required for the MRI pulse programmer: a 32-bit RISC CPU core, 62 Kbytes of flash memory, 8 Kbytes of SRAM, two 32-bit timers, four 12-bit DA converters, and 40 bits of general purpose I/O. An evaluation board for the microcontroller was connected to a host PC, an MRI transceiver, and a gradient driver using interface circuitry. Target (embedded) and host PC programs were developed to enable MRI pulse sequence generation by the microcontroller. The pulse programmer achieved a (nominal) time resolution of approximately 100 ns and a minimum time delay between successive events of approximately 9 μs. Imaging experiments using the pulse programmer demonstrated the effectiveness of our approach.

We developed a fetal magnetocardiography (fMCG) system that uses a pair of two-dimensional gradiometers to achieve high signal-to-noise ratio. The gradiometer, which is based on a low-Tc superconducting quantum interference device, detects the gradient of a magnetic field in two orthogonal directions. Gradiometer position is easy to adjust by operating the gantry to drive the cryostat in both the swinging and axial directions. As a result, a fMCG waveform for 25 weeks' gestation was measured under an unshielded environment in real time. Moreover, the P and T waves for 25 and 34 weeks' gestation, respectively, were obtained by averaging. These results indicate that this two-dimensional gradiometer is one of the most promising techniques for measuring fetal heart rate and diagnosing fetal arrhythmia.

A local radio frequency (rf) shielding consisting of a Cu plate and an LC balun circuit has been developed for a compact magnetic resonance imaging (MRI) system with a 0.3 T permanent magnet. Performance of the local rf shielding was evaluated using an artificial external noise source irradiating a human subject whose hand was inserted into the rf coil of the MRI system. Power spectra of the rf signal detected through the rf coil demonstrated that the local rf shield achieved 30.1 dB external noise suppression. With the local rf shielding, a MRI of the subject's hand was performed using a three-dimensional gradient-echo sequence. Anatomical structures of the subject's hand were clearly visualized. It was concluded that the local rf shielding could be used for the compact MRI system instead of a rf shielded room.

By combining a 0.3 T permanent magnet with flexible rotation and translation mechanism, a probe with a local electromagnetic shielding, several electrical units, a mobile lift, and an electric wagon, a mobile magnetic resonance imaging (MRI) system was developed for outdoor tree measurements. 2D cross-sectional images of normal and diseased branches of a pear tree were acquired for measurements of T1, T2, proton density, and apparent diffusion constant (ADC). The ADC map clearly differentiated diseased from normal branches. A whole-day measurement of the ADC map demonstrated that microscopic water flow in the normal branch changed proportionally with solar radiation. Therefore, we have concluded that our mobile MRI system is a powerful tool for studies of plants in outdoor environments.

We developed a video recording system with the capability of tracking moving objects and used it to track the flight of an insect. The system consists of two galvano mirrors, which redirect the light coming from the object in two orthogonal directions toward a high-speed camera to capture the image. An additional high-speed camera, which views the same object through a beam splitter placed between one of the galvano mirrors and the observation camera, detects the position of the object. The mirror angle is controlled to maintain the position of the object at the center of the view, allowing the object to be tracked. In order to validate this system, images of a live fly in flight were recorded along a flight path that was much longer than the field of view of the stationary camera. A high-resolution video image of a rapidly moving live fly was successfully captured.

近年,CT装置の急激な進歩による検出器の多列化と,X線管球回転速度の高速化に伴い,短時間に高精細なVolume dataの取得が可能となってきた.またVolume dataを処理するワークステーションの進歩により,三次元画像が臨床現場でも積極的に利用されており,特にCT Angiography(CT-A)の分野では検査目的に応じた様々な撮影方法が検討されている.肺の動静脈や気管支は各区域別に分布しているがバリエーションも多く,時には隣接する肺葉を超えて分岐する異常構造が認められることがある.そこで,術前に肺動静脈や気管支の走行を,非侵襲的な検査であるCT-Aにてある程度把握することは,迅速かつ安全な手術を行う上で重要であると考える.当院でも,2009年01月~2010年10月までに,約60例の肺腫瘍および縦隔腫瘍術前CT-Aを実施してきた.今回当院での現状及び改善点をまとめたので紹介する.

Polycystic kidney disease (PKD) is a hereditary disorder with abnormal cellular proliferation, fluid accumulation in numerous cysts, remodeling of extracellular matrix, inflammation, and fibrosis in the kidney and liver. The two major types of PKD show autosomal dominant (ADPKD) or autosomal recessive inheritance (ARPKD). ADPKD is one of the most common genetic diseases, with an incidence of 1:500–1,000. Approximately 50% of patients with ADPKD develop end-stage renal disease (ESRD) by the age of 60. On the other hand, ARPKD is relatively rare, with an incidence of approximately 1:20,000–40,000. ARPKD is diagnosed early in life, often prenatally. The gene products responsible for ADPKD and ARPKD distribute in primary cilia and are thought to control intercellular Ca2+. Two types of animal model of PKD have been established: spontaneous hereditary models identified by the typical manifestations of PKD and gene-engineered models established by modification of human orthologous genes. Both types of animal models are used to study the mechanism of cystogenesis and efficacy of medical treatments. In PKD progression, critical roles of signaling pathways including MAPK, mTOR, and PPAR-γ have been discovered with these models. Therefore, experimental animal models are indispensable for investigating molecular mechanisms of PKD onset and progression as well as potential therapeutic treatments.

In this study, we aimed to determine the effect of trehalose coating and the optimal dose of basic fibroblast growth factor (bFGF), an osteoinductive protein, loaded onto tailor-made bone implants for implant-induced bone formation in vivo. We fabricated tailor-made α-tricalcium phosphate bone implants (11 mm diameter with 2 parallel cylindrical holes). bFGF 0, 1, 10, 100 or 200 μg/implant was incorporated into implants with and without a trehalose coating, and these were subsequently implanted into dogs to correct temporal bone defects of the same size and shape. Four weeks after implantation, we analyzed the bone implants and surrounding tissues by using micro-computed tomography imaging and histological analyses, as well as gross evaluation. No significant difference in new bone formation was observed between implants with and without trehalose coating at any of the bFGF doses. Bone implants with 100 and 200 μg bFGF showed significantly more new bone formation at the implant site and within the cylindrical holes of the implants than those without bFGF (P<0.05). However, heterotopic bone formation on the skull near the implant was observed in the group that received 200 μg bFGF. These results suggest that 100 μg bFGF is the optimal dose for this implant in dogs, and that the trehalose coating may not be necessary in vivo, probably due to the presence of blood proteins and electrolytes at the implant site.
