A devastating earthquake measuring 7.2 on the JMA (Japan Meteorological Agency) magnitude hit the southern Hyogo Prefecture on January 17, 1995. This earthquake, the worst in Japan since the Great Kanto Earthquake in 1923, brought great disaster and destruction to the Hanshin area and Awajishima Island. Most of the damage to concrete and steel structures occurred in buildings designed according to former building codes. Fewer collapses occurred in buildings designed under current building code that have more severe seismic requirements. Existing buildings should be assessed by their seismic potentiality, and retrofitted to escape damage in severe earthquakes such as the Great Hanshin Earthquake. New technology for assessing and retrofitting existing buildings was developed to improve resisting performance in response to severe earthquakes. Earthquake Load or motion exceeding current requirements can be supplied to assess and retrofit existing buildings if a client wants their buildings to exhibit much stronger seismic resistance. The retrofit technologies, such as a base isolation system for whole building, vibration control bracing system with steel damper, and base isolation floor system for computer equipments, can be applied to existing buildings. 11 refs., 9 figs., 8 tabs.

In order to complement an anomaly diagnosis system by analysis of gases in oil for transformers, the analysis/diagnosis method of trace constituents in oil was developed. Liquid-liquid solvent extraction using methanol aqueous solution as extract, and high-speed liquid chromatography were adopted to analyze decomposed products dissolved into oil by over heating as trace constituents. The relation between over heat temperature and the amount of decomposed products by over heating was studied by simulation experiment of over heat anomaly. The detectable duration of anomaly after its generation was also studied by examining the adsorption phenomenon of the thermal decomposed products onto insulating materials. As a result, the criterion of the analysis/diagnosis method was prepared by using 5-hydroxymethylfurfural as index constituent of over heating anomaly. Although furfural was also effective as index constituent, it was excluded from the index constituent because furfural is formed by deterioration of transformers even during normal operation. 2 refs., 19 figs., 7 tabs.

Medical application of lasers is rapidly expanding in accordance with the development of laser technology. However, it is difficult to predict how light propagates and is absorbed by living bodies because of strong scattering of light by biological tissues. Therefore, the determination of light dose has been based on experience. This fundamental study aims to develop a imaging simulator which can predict propagation of light and its effectiveness in medical diagnostics and therapeutics. Teoretical models of light propagation in biological tissues have been constructed, and experiments have been conducted to validate the theoretical calculation. In the theoretical calculation, a three-dimensional model which simulates a human head with five layers of different tissue types. Numerical calculation has been done by using the finite element method to simulate the propagation of ultrashort pulse light, and it is shown by a computer graphics technique for the first time in the world. In the experiment, a solid phantom which anatomically and optically simulates a human head based on MRI images has been fabricated by using the optical prototyping technology for the first time in the world again. Also, we have compared the experimental results of the transmitted light through the solid phantoms with the theoretical results and have succeeded in reconstructing the tomographic images of optical properties.

The high-precision diagnosis for deterioration of a breathing transformer containing an adsorbent was investigated. An adsorbent (activated alumina) may be contained in oil to eliminate the deterioration product in insulating oil or the moisture. In this case, the deterioration component furfural in insulating paper is adsorbed. The concentration in furfural oil cannot be thus used for deterioration diagnosis. Acetone and furan with good relation between the adsorption characteristics for activated alumina and the insulating paper deterioration in an accelerated deterioration test can be effectively used as a new deterioration index component of insulating paper. The disassembly survey showed that acetone is valid as the index component of deterioration diagnosis. Furan is not detected in a breathing transformer, but effective in diaphragm-type and nitrogen-sealed transformers. The adsorption of acetone by activated alumina requires no correction for the change in oil temperature at about 10{degree}C. The solubility of acetone for insulating oil is 60 times at 20{degree}C as high as CO2, and the discharge rate from a breather is little (1/25). Therefore, acetone is much more excellent than CO2 as the precision of a deterioration index. 21 refs., 15 figs., 4 tabs.

The diagnosis method of aging deterioration was proposed for oil filled transformers based on detection of furfural in insulating oil. Vacuum, oxygen-added and water-added specimens of insulating paper immersed in insulating oil were thermally deteriorated at 120-180 {degree}C for 1-120 days to measure average polymerization degrees of the insulating paper and furfural contents in the oil and paper. As a result, the addition of oxygen or water accelerated forming of furfural, and the average polymerization degree considerably decreased in the early stage of heating. There was also the certain relation between the furfural content and average polymerization degree. In addition, various kinds of subjects were discussed which were required to apply these experimental results to diagnosis of aging deterioration in real oil filled transformers, and rough furfural contents corresponding to aging deterioration degrees of the insulating paper were given. As combined with a CO{sub 2} + CO method, the proposed method was expected to be more reliable. 9 refs., 8 figs., 2 tabs.

Structure and velocity measurements using magnetic resonance imaging (MRI) have been performed experimentally to obtain a correlation between pore structure and interstitial flow through the packed bed of 5 mm diameter in the tube of 36 mm ID. To measure axial velocity maps of water flow through the packed bed, the phase method of using the phase difference of water spin magnetization between flowing and stagnant fluids by applying magnetic fields with bipolar gradients was employed. The spatial resolution of the obtained map in 0.2 mm x 0.2 mm x 0.5 mm. It was made clear from the obtained axial velocity maps that channel flows with higher axial velocity were induced not only near the wall but also in the internal region of the packed bed. Furthermore, pore structure of the packed bed was characterized from multi-slice images by partitioning of void space and combining of each pore section along the axial direction to analyze the structure-flow correlation. It was found from image analysis that axial channels with long and straight void space existed in the pore structure, and that most of the channel flows with higher axial velocity were induced in the axial channels. The flow rate through an axial channel depends on the square of the averaged cross section of the axial channel. (author)

The research and development project is conducted to develop new methods directly related to early discovery of potential cancer patients, and the FY 2000 results are reported. The FY 2000 efforts are directed to improvement of intra-Alu-PCR method as the superhigh-sensitivity quantitative method, almost established in the previous fiscal year, to have higher reliability and simplicity suitable for automatic diagnosis. It is concluded that (there is no difference of significance between normal persons and cancer patients in free DNA concentration in the blood, determined by the Boyle/intra-Alu-PCR method), but this method is confirmed to be useful for prognostic monitoring of the patients who have the marrow or peripheral vessel cell transplant. Detection of qualitative gene abnormality of DNA in the peripheral vessels is investigated using the K-ras, p53 gene. Certain results are obtained by the MSA method for the former, and by the newly introduced WAVE DNA fragment analysis system for the latter. However, there are still a number of problems to be solved before these methods are applicable to screening for general medical examinations. The research on the (analysis of gene abnormality of cancer itself) has made a notable progress. (NEDO)

To obtain the basic data to develop instruments for diagnosis of atherosclerosis and to elucidate the mechanisms of atherogenesis by focusing on the autofluorescence of blood and vascular walls of atherosclerotic animal models and human patients. We have performed experiments to examine the relationships between autofluorescence of blood and vascular walls of guinea pig atherosclerotic model and human patients and obtained the following results. 1. The autofluorescence from human atherosclerotic aorta included the components with longer wave length than normal aorta, suggesting that diagnosis of atherosclerotic aortic walls will be possible using spectroscopic analysis through glass fiber catheter into vascular system. Further studies should be needed to the quantitative diagnosis. 2. The autofluorescence from blood plasma of human atherosclerotic patients has showed that the peak wave length was shorter than that of normal plasma. This phenomenon was mainly caused by the oxidization of plasma, especially lipoproteins, LDL and HDL. 3. Atherosclerotic model of the guinea pigs was quite similar to human atherosclerosis at the points of cholesterol levels and localization of lipid deposit to arterial walls, and showed to be useful for the studies of atherosclerosis.

The aim is to develop a highly reliable device for detecting pathological developments deep inside the body by combining the pulse compression technique used in high performance radars and a quartz fiber. The project also aims to develop a system which, when compared with the conventional method, is capable of higher resolution at a short range and of reaching farther for the same resolution level. To be contrived for the development of a diagnostic catheter which combinedly uses the ultrasonic pulse compression and imaging technology and an optical picture system are a pulse signal reflection mirror for taking in ultrasonic picture data on the front and the sides in the lumen, an ultrasonic micromotor for rotating the mirror, and a high efficiency ultrasonic transducer similar in size to the waveguide for transmitting ultrasonic pulses to a quartz waveguide from outside the body and for receiving reflected signals. An effort is simultaneously exerted to make the diameter smaller of a quartz waveguide to be built in the catheter to provide a signal passage for the ultrasonic imaging system and the optical picture system for the realization of a catheter tip smaller and thinner as a whole. A study is made about a mechanical-electronic control system for easy luminal insertion. (NEDO)

An ultrasonic probe with its point fine is navigated in blood vessels and body cavities by 3-dimensional ultrasonic signals (with the oscillator driven by transmission from a catheter for position detection) for the acquisition of accurate 3-dimensional ultrasound images in a less invasive way. The transmission and reception circuits are provided with circuits for ultrasound tomographic images and for navigation. Trial units are fabricated and tested for transmission waveform and reception performance. The scanner is rotated for the acquisition of intravascular 3-dimensional radial images. The scanner rotating rate is set at 30 rps for the scanner performance not to be affected by heartbeat and the rate is controlled by the observation unit which changes voltage for the control. The 3-dimensional display software program, thanks to the navigation function of the external probe, detects the external probe position relative to the small-diameter probe for the construction of accurate 3-dimensional images. Specifications for a total system, which makes full use of a navigation function, are compiled, consisting of a small-diameter probe and a body surface real-time 3-dimensional display. (NEDO)

The device is now satisfactorily capable of all image processing functions (bi-levelling, color deviation, brilliance adjustment, etc.) with the exception the karyotyping function. A substance that emits fluorescence by laser excitation is developed (for labelling the probe). A direct labelling method is studied, in which nucleic acid probes (nucleic acid labelled for chromosomal identification) will prove to be remarkably high in sensitivity. A new fluorescent reagent is synthesized, which is a BHHCT-4-dUTP to act as a nucleic acid probe. It is found that the new substance is superior to the conventional fluorescent substances in terms of stability and that all chromosomes may be forced into hybridization (selective combination of a probe with a peculiar chromosome) when various probes are labelled by this substance. A programing unit is constructed for a chromosomal aberration database. Items needed relative to chromosomes and parameters relative to chromosomal aberration data are appropriately arranged, and conditions to satisfy for their development into a database are studied.

In solving the problems in developing technologies peculiar to developing countries, Japan will provide cooperation. This paper describes the achievements in diagnosis and survey in fiscal 1994. Development will be made on a manufacturing process for dimethylether (DME), a synthesizable and portable clean fuel, by using coal produced in China. Annual DME production of 10,000 tons will make it possible to supply 50,000 households with the fuel of one year consumption, whereas return on the construction investment and profit can be expected. At the Shanxi Coal Chemistry Research Institute, a 500 tons a year plant making DME from gasified coal gas is scheduled to begin operation. Development will be made on a pulp manufacturing technology in China, in which environmental pollution due to waste water is largely reduced, and operation cost is reduced. Application of the oxygen-alkaline evaporation and decomposition process developed in Japan will be considered, which uses non-wood raw material such as rice straw, wheat straw and megass). The raw materials are immersed continually in low-concentration alkaline solution, dehydrated, and then lignin is oxidized and decomposed by using oxygen in a continuous oxidation reactor to make the material into pulp. China uses non-wood materials as paper raw materials at 80%, whereas effects are expected in waste water pollution prevention, energy saving, resource saving and economics. (NEDO)
