A novel life-rhythm analysis system, which secures safety of living-alone seniors by sensor network, has been developed. Sensor network consists of sensor nodes which are composed of various sensors, CPU and a wireless communication module. Sensing data are transferred to the host computer through wireless communications among sensor nodes. Since the sensor network enables us to place processors and various kinds of sensors in any places, we can not only obtain much more life-rhythm information, but can also control electric appliances in the household. The developed system acquires sensing data from sensor network and transfers them to a database on a host computer through internet. Clients access the database through web browsers. The system was applied to measurement of actual home environment. As a result, it was shown that many kinds of life rhythms, such as washroom usage, rising hour, bed time, coming-home time, can be obtained at a time. Also it was confirmed that each sensor node can control external devices, such as LEDs. From these evaluations, we can say that the system is very promising for remote sensing of an extraordinary life rhythm of living-alone seniors and coping with such an unusual situation.

The synergistic extraction of rare earth elements has been investigated by a mixture of a high molecular weight β-diketone, dibenzoylmethane (Hdbm, HA), and a new neutral ligand (S), 3, 5-di (2-pyridyl) pyrazole (dpp), as well as a typical neutral bidentate ligand, 2, 2'-bi-4-picoline (bp). Large synergistic enhancement was produced owing to the formation of the adduct complexes such as MA_3S in both neutral ligand -systems. Extraction constants with Hdbm alone and those in the presence of the neutral ligand were evaluated for rare earth elements, and the adduct formation constants for dpp was found to be close to those for bp. The separation factors for lighter rare earth elements were also enhanced through the synergistic effect with dpp and bp.

At early stages of heat-induced association-dissociation behavior of soybean glycinin of 10% protein concentration, gelation process was investigated by sucrose density gradient centrifugation (SDGC) and polyacrylamide gel electrophoresis (PAGE). Soluble aggregates (MMSA) formed within 3 min contained unknown components X, which are likely oligomer consisting of intermediary subunits (IS). This result indicates that the disulfide (SS) bridge formation through intermolecular disulfide exchange among fold and/or still unfold glycinins participates in the formation of MMSA even on heating at 1 min. With increasing in heating time, the disappearance of this X was consistent with the appearance of acidic subunit oligomer or polymer. Another soluble aggregates (HMSA) at bottoms after ultracentrifugation had similar subunit oligomer composition to that of the insoluble fractions in the gel of final heat-induced products.

A macrocyclic glycocluster host molecule (Glu-Host) which has a strong polar sugar-cluster part interact with many dyes via hydrogen-bonding in a polar solvent. The interactions are detected by UV-VIS spectroscopic change due to host-guest complexation. Especially, UV-VIS spectra of all triphenylmethane type dyes such as Brilliant Blue G are changed. Bingding constants of some dyes are able to calculate and these host-guest interactions are very strong because the binding constants calculated are large value.

Transglutaminase, catalyzing the formation of polymers through ε-(y-glutamyl) lysyl crosslinks between the glutaminyl residues and the lysyl residues, was usefully used in order to give evidence for polymerization of acidic subunit as a thermal gelation initiator. Electrophoresis of transglutaminase-treated glycinin indicated that acidic subunit was selectively polymerized in the native glycinin molecule, but not the counterpart basic subunit. When the transglutaminase-treated glycinin was heated at various protein concentrations, it became gelled even at 2 % protein concentration. This result implies that artificial polymerization of acidic subunit inhibits releasing of acidic subunit from soluble aggregate and precipitation of basic subunit monomer, oligomer and polymer, and so that polymerization of acidic subunit initiates or accelerates thermal gelation of glycinin.

Until, the most of studies concerning a high strength bolt friction joint was the studies by way of experiment. The distribution of contact pressure and the fricative force is considered that has influences on the stress distribution of contact surface. The purpose of this study is grasping for a difference of dynamics property when changes the thick of splice plate and the coefficient of friction for the circumstances before main slip of the high strength bolt friction type potion by 3 dimensional elastic-plastic model.

The analysis model in a finite element method is enlarged and complicated by improvement in the fast performance of a computer. Time to use for the work, which gives element division to the candidate for analysis than the calculation time in the main of analysis, becomes large. Time shortening in an element division and Optimization of element form are required in order to improve analysis efficiency. In this research, the process of the element division into a stress concentration part was logically expressed using fuzzy reasoning.

For a golfer, to hit a ball as long as possible can be the greatest desire, and in order to fill the desire, the degree of concern to golf gears becomes stronger, which can be said to be a major factor of progress in golf. So, in this report, golfers' actual swing feeling was investigated and analyzed about the influence of the difference of the diameter of a tip on swing. As a result, the following has been grasped. Although analyses in consideration of the conditions of the skill of golf such as differences in head speed and handicaps were carried out, a shaft with a thicker tip, having nothing to do with these conditions, was predominant in swing feeling.
