| 抄録 | A new stepwedge has been developed for bootstrap sensitometry, which is used for determining the characteristic curve of radiographic screen/film systems. Since each step of the stepwedge is separated by the lead septum, flare generated under one step will not penetrate the region of another step. The metal of the stepwedge can be changed with various materials. Characteristic curves obtained with new stepwedge bootstrap (NSB) and conventional stepwedge bootstrap (CSB) techniques were compared with those obtained for screen/film systems with inverse sqare sensitometry. The inverse square method was used as the reference standard for accuracy. The NSB method provided characteristic curves that agreed well with those obtained using the inverse square method. The slope of the curve in the CSB method was lower than that in the inverse square or NBS method, because of scatter radiation. The shape of the characteristic curve from the NSB method did not vary with the materials of step metals (aluminum and copper). The cumulative error involved when using the bootstrap method is also discussed. |

| 抄録 | Judzing from this, club activities must be included not in school education but in adult education. And so club activities in school must be practiced from the point of adult education. It seems, however, that the accepter has not been prepard yet. For the reason, It is impossible to exclude club activities at once from school education. From this point, the system of life-long education must be made up promptly and club activities are preferable to be separated from school education. On both sides of school education and adult education, the administrative readjustment must be excuted first of all for the activities of school clubs being pushed forward. It seems, however, that the problems are in Shido-yoryo itself: especially how to deal with Tokubetsu-katsudo is the problem. In other words, Shido-yoryo says, "Tokubetsu-katsudo must be separated from adult education" or "It is not practiced necessarily in adult education" in one time and "It has been applied corresponding to Bukatsu instead of Kurabu" in another time. Shido-yoryo has influenced greatly on the activities in school education. |

| 抄録 | Evaluation of dental implantation is very important because it gives useful information for both planning the dental treatment and evaluating of prognosis. This study aimed at improving our previously developed Tooth Mobility (TM) tester and developing a dental implant movement (IM) checker. The measuring probe included a bimorph transducer of two piezoelectric elements. It was actuated by single frequency and detected tooth acceleration. The acceleration signal was processed and the IM score was calculated in PC. Two artificial implant models in which IMZ implant was buried with different elasticity of surrounding (molteno(@)) were used to examine the performance of the IM checker. The IM scores obtained in the models were 29 and 58. The measurement time was below 15 seconds. The average of measurement variation of one operator was below 6% and the average variation among five operators was below also 6%. The IM checker reduced a measurement variation by 51% and a measuring time by 61% compared with those of the TM tester in natural teeth. The newly developed IM checker had sufficient measuring reliability and we could objectively estimate the implant movement in dental clinics. |

| 抄録 | Engineers have long sought the possibility of measuring parameters such as temperature and pressure continuously in the underground with high precision, high spatial resolution and high band width of parameters. Distributed fibre optic measurement offers the use of a very fast, robust, precise, light and small gauges with an high spatial resolution. In this paper we would like to compile fibre-optic measure-methods which are available now for projects in geohydraulical engineering. This paper will propose new problems for future research work on parameter identification for such parameters as conductivity and anisotropy. |

| 抄録 | In functional principal component analysis (PCA), we treat the data that consist of functions not of vectors (Ramsay and Silverman, 1997). It is an attractive methodology, because we often meet the cases where we wish to apply PCA to such data. But, to make this method widely useful, it is desirable to study advantages and disadvantages in actual applications. As alternatives to functional PCA, we may consider multivariate PCA applied to 1) original observation data, 2) sampled functional data with appropriate intervals, and 3) coefficients of basis function expansion. Theoretical and numerical comparison is made among ordinary functional PCA, penalized functional PCA and the above three multivariate PCA. |

| 抄録 | The objective of this paper is to delineate flood prone areas and estimate damage in Greater Dhaka during the 1998 catastrophic flood using an integrated approach of GIS and remote sensing. Time series RADARSAT SAR data is acquired and used to demarcate flood boundaries for the 1998 flood event. This was accomplished by thresholding linear SAR imageries. Flood estimation demonstrated that flood areas steadily increased from early July 1998 and peaked on 25 August 1998 inundating 53% lands due to heavy monsoonal downpour and discharge from upstream points. Different thematic layers were combined with a derived flood map in order to assess flood damage for the same event. Flood damage analysis revealed that substantial damage has occurred in Greater Dhaka during the 1998 flood. |

| 抄録 | Fluorine-containing poly(ether ketone)s was synthesized by the nucleophilic aromatic substitution reaction of 2,2-bis(4-hydroxyphenyl)-1,1,1,3,3,3-hexafluoropropane and 4,4'-bis(2,3,4,5,6-pentafluorobenzoyl) diphenyl ether in super-critical CO(2). Polymerizations were carried out at 80℃ for 6 hours under 5000 psi of CO(2) pressure, which was super-critical phase. Polymerization concentration was 0.5 g of polymer in 10 - 12 mL of CO(2). The polymer was not obtained in CO(2) due to the insolubility of both the potassium bisphenoxide and the polymer into CO(2). However, the polymer was formed by an addition of DMAc and NMP in CO(2), even though molecular weight was not so high. Very small amount of co-solvents which were immiscible with CO(2) was effective, and it was 1/20 - 1/25 amount of the solvent used in the conventional poly(ether ketone) synthesis. The polymerization mechanism was also discussed. |

| 抄録 | Sensitivity to water condition during germination is an important character in malting barley because it affects malt poduction. Water sensitivity in malting barley is defined as the defference in germination percentage between the seeds in standard and excess-water conditions. Usually standard and excess-water condition means 4 and 8 ml water in a 90 mm perti dish, respectively. Takeda and Fukuyama (1983) examined more than 4,000 barley accessions and found 0～100% water sensitivity. This means complete to no suppression of germination by an excess-water condition. In this study, quantiative trait loci (QTL) analysis was applied to analize the inheritance of water sensitivity. Two sets of doubled haploid (DH) populations derived from Steptoe×Morex (S/M) and Harrington×TR306 (H/T) crosses,were grown in the experiment field of the Research Institute for Bioresources, Okayama University. Bulbosum method was adapted to develop DH lines (Chen and Hayes 1989). Water sensitivities of 150 (S/M) and (H/T) lines and their parents were evaluated using 50 seeds each and the germination test (25℃, 4 days) was repeated four times. Water sensitivity showed a large variation (Fig.1) and the heritability of the trait was 0.78 and 0.72 in S/M and H/T, respectively, indicating that about three-quarters of the phenotypic variance was genetic in origin. Three (S/M) and one (H/T) significant QTL were detected and 23% (S/M) and 25% (H/T) of the phenotypic variance was explained by the QTL. These QTL were located on chromosomes 2H,3H,6H and 7H (Table 1, Fig. 2). QTL relating to germination traits were lacated near the QTL controlling water sensitivity (Fig. 3). Interaction among the QTL was small (Table 2). Marker-assisted selection was effective (Table 3). |

| 抄録 | The thrips Ponticulothrips diospyrosi Haga et Okajima is an univoltine species which aestivates and overwinters in the adult form in the fields. The oviposition factors of the thrips were investigated on persimmon seedling leaves. The adult female could make a gall and oviposit inside it in vitro. Female could make a gall and oviposit at 20℃, but only make a gall at 15℃. Although it could neither make a gall nor oviposit at 25℃, it oviposited at than temperature when placed on a gall. Female neither made a gall nor oviposited on an extended young leat. However, it could oviposit on the young leaf rolled artificially in a line tube (3.2 mm diam.), but not on the old one. These findings show that univoltine of the thrips may be regulated by the phenology of the host plant and females can oviposit whenever they are placed on the seedlings at the optimum oviposition temperature. |

| 抄録 | Rove beetles have a pair of pygidial excretory organs, each group secretes characteristic substances in a peculiar manner. The genus Stenus has a pair of pygidial organs, eversible by immersion in diethyl-ether at both sides of the anus. S. anthoracinus, S. melanarius vercecundus and S. rufescens were collected at ponds and river shores, and S. alienus was collected at tobacco and vegetable fields. Excretory substances were secreted in the diethylether, and identified by gas chromatography and mass spectrometry. Stenusin [N-Ethyl-3-(2-methylbutyl) piperidine], 1,8-cineole, isopiperitenol and 6-Me-5-hepten-2-one were identified. These may probably act as defensive substances against small attacking animals and microorganisms, and act as water suface moving active agents. |

| 抄録 | Seven hundred and thirty varieties of soybean from different sources were evaluated for seed flooding tolerance by the seed germination test after a 4-day soaking at 25℃. The inheritance of seed flooding tolerance was also analyzed with a 6 x diallel cross. A large variation in seed flooding tolerance existed in the soybean germplasm as reflected in the germination rate which ranged from 0 to 100%. Most of the varieties tested were sensitive to seed flooding, and only 4% of the tested varieties showed a high tolerance (germination rate >90%). Seed flooding tolerance was controlled by both additive and dominance genes and a small number of effective factors and high narrow sense heritability in diallel analysis indicate that the selection for tolerance can effectively be done in early generations. |

| 抄録 | The host selection, development and reproduction of sugarcane aphid, Melanaphis sacchari (Zehntner) were studied. Both alate and apterous virginoparous adults showed a stronger tendency of preference to a susceptible strain of sorghum and Cuba grass, Sorghum helepense (Persoon) than a resistant strain of sorghum and Eulalia, Miscanthus sinensis (Anderss). The number of days for larval development was increased with a decrease in longevity and fecundity in aphids reared on resistant sorghum at 25℃ under a 16-hour photoperiodic condition. |
