Cannabis seeds not pretreated for prevention of germination are on sale through the Internet in recent years. These seeds are illegal and show a high probability of germination. The number of arrestees, who had cultivated illegal Cannabis seeds, has increased year after year.<br>   Recently, we had an opportunity to examine Cannabis seeds. We carried out experiments for the proof of the germination abilities by usual and embryo-exposure techniques. The embryo-exposure technique is a speedy and effective method for germination of Cannabis seeds, especially for the weakened seeds.<br>   In this study, we have reported and recorded the course of germination, how to determine the germination and the growth process of Cannabis.<br>

△^9-Tetrahydrocannabinol (△^9-THC), cannabinol, cannabidiol and cannabichromene were detected in commercially available cannabis seeds by silica gel TLC and gas chromatography. These cannabinoids existed in rather high content (0.10-2.02mg/100g of seeds) in the feed for birds, especially bracts (82.3-441mg/100g). When the suspension prepared from the benzene washing solution of cannabis seeds, BenW, was administered at a dose of 3mg/kg corresponding to △^9-THC into a mouse, i.v., BenW caused hypothermia, catalepsy, pentobarbital-induced sleep prolongation and suppression of locomotor activity. These pharmacological activities of BenW were significantly higher than those of △^9-THC (3mg/kg, i.v.). These results may indicate the necessity to reconsider the present regulations on marihuana.

This study aims to evaluate strength of a diamond-like carbon (DLC) film on a metal for glass press molding at high temperature. Static and cyclic indentation tests at high temperature up to 300℃ with AE monitoring technique were performed. AE monitoring reveled crack generation load or cyclic number during the indentation tests. The static strength of the films at each temperature was determined from maximum stress in the film in the radial direction induced by sink-in deformation due to static indentation. The maximum stress at each temperature was estimated with indentation loads at first AE generation and FEM analysis. Thermal stress in DLC film was at each temperature also calculated. The film strength estimated by taking the thermal stresses into account was decreased with an increase of temperature. In cyclic indentation test, AE due to cracks in film was detected after 1.0×104 cycles at the load where no crack generated under one loading cycle. The cyclic number to crack initiation for the sample in 300℃ was 1/50 smaller than that in room temperature.

本稿は,リチャード・マルカスタ一の教育論の考察を通して,イングランドの後期ヒューマニストの教育論の特微とその背景,およびその教育史的意義を明らかにすることを課題としたものである。 マルカスターの教育論の主たる特徴は,前期ヒューマニストが古典語を重視したのに対し,彼らは母国語(英語)教育を重視したことである。その理由・背景は,宗教改革による福音主義の浸透に加え,ナショナリズム,英語の普及・標準化,国語意識の目覚めなどがある。 また, もう一つの特徴は,身体の訓練の必要性・重要性を唱えたことである。この主張の理由.背景は,彼が,身体を「肉(fresh)」と捉える観念的・教条的な見方から脱却し,身体と精神の関係を善悪や喜怒哀楽の「協同者(copartner)」とみたからである。 マルカスターの教育論は,前期ヒューマニストの教育論の古典主義を超えて,ラトケやコメニウスの母国語重視の教育や国民教育の構想,さらにロックの健全な身体と健全な精神を結びつけた教育論につながる位置にある。 Summary : This paper's aim is to study on Richard Mulcaster's thought conceming education. He was one of the humanists at the later English Renaissance. He was the headmaster of Meacant Taylors' School from 1561 to 1581, and St Paul's School from l596 to 1608. One of his main opinions is to make much of teaching English. The causes of the opinion are the spread of evangelicalism as the result of the Reformation, nationalism, popularizatin and standardization of English, and becoming conscious of mother tongue. Another proposition is to encourage training body. The reason is that he thought the soul and the body being copartners in good and ill, in sweet and sour, in mirth and mourning, and having generally a common sympathy and a mutual feeling in all passions. Mulcaster's thought concerning mother tongue was taken over by Wolfgang Ratke (1592-1635) and Jan Amos Comenius (1592-1670). And another propositin of training body was taken over by John Locke ( 1632-1704).

The field of open-ended cognitive tasks in the experimental sensory deprivation is reviewed with the aim of attaining a frame-work which systematize many experimental findings. Major studies were discussed briefly. The following hypothesis was supported ; sensory deprivation impaired the higher order function of human beings, because sensory deprivation impaired or deteriorated the functions of organizing, apperceiving and verbalizing the cognitive objects, which can be regarded as the higher order function of human beings. Moreover, open-ended cognitive tasks were divided into three types according to the condition of the performance. The open-ended task consists of the way of the performance, the stimulus and a goal, then (1) the stimulus is self-imposed, and the goal of the task is unknown, self-defined and unstructured, (2) the stimulus is given, and the goal of the task is unknown, self-defined and unstructured, (3) the stimulus is given, the goal of the task requires the agreement with a certain criterion. Within 24 hrs. to 48 hrs. sensory deprivation, the deteriorative effects of sensory deprivation on the performance of the openended cognitive task were weakened in the degree that the open-ended cognitive task have some characteristics of the closed-end cognitive task, whose solution depends on the use of overleaned, structured and logical steps to reach a definite answer.

New viscosity measurement technique by using rotational breakup of electrostatically levitated droplet was developed. The new one-dimensional viscosity measurement equation is derived by integrating three-dimensional momentum equation based on the assumptions with axisymmetric shape and internal flow of levitated droplet. From the measurement result obtained, internal flow around the center of the dumbbell shape droplet is axisymmetric along the elongational axis. This result means that the present proposed new method is appropriate. In the present study, high accuracy image processing technique is applied to obtain the shape and curvature around the center of the dumbbell shape droplet by using the transformation to rotating coordinate system. The present technique can be applicable after the breakup start and before the shape of the droplet becomes asymmetric. This is reason why Euler force becomes so large that the symmetricity cannot be sustained. The newly proposed viscosity measurement technique makes it possible to estimate the viscosity within 10 % error in the range of the viscosity which the previous levitation technique cannot be available.

Shoot, adventitious root and hairy root cultures of Solidago altissima L. were established. Chlorogenic acid and 3, 5-dicaffeoylquinic acid were isolated from the hairy root cultures. 3, 5-dicaffeoylquinic acid was the major secondary metabolites in various tissue cultures of this plant. These polyphenol compounds were easily isolated as the polyphenol-soybean protein complex from the extract of this plant. Solidago altissima L., producing polyphenol compounds with the high concentrations, seemed to have a potential to be as a new resource for functional compounds.

We investigated the utility of triple-phase helical computed tomography (CT) in differentiating between benign and malignant splenic masses in dogs. Forty-two dogs with primary splenic masses underwent triple-phase helical CT scanning (before administration of contrast, and in the arterial phase, portal venous phase, and delayed phase) prior to splenectomy. Tissue specimens were sent for pathological diagnosis; these included hematomas (n=14), nodular hyperplasias (n=12), hemangiosarcomas (n=11), and undifferentiated sarcomas (n=5). The CT findings were compared with the histological findings. Nodular hyperplasia significantly displayed a homogeneous normal enhancement pattern in all phases. Hemangiosarcoma displayed 2 significant contrast-enhancement patterns, including a homogeneous pattern of poor enhancement in all phases, and a heterogeneous remarkable enhancement pattern in the arterial and portal venous phases. Hematoma and undifferentiated sarcoma displayed a heterogeneous normal enhancement pattern in all phases. The contrast-enhanced volumetric ratios of hematoma tended to be greater than those of undifferentiated sarcoma. Our study demonstrated that the characteristic findings on triple-phase helical CT could be useful for the preoperative differentiation of hematoma, nodular hyperplasia, hemangiosarcoma, and undifferentiated sarcoma in dogs. Triple-phase helical CT may be a useful diagnostic tool in dogs with splenic masses.

多層ハロゲン化銀カラー写真感光材料を用いることにより, イオン粒子線飛跡の3次元情報を得る新しい手法を開発した。市販のカラーフィルムに粒子線を照射した。飛跡の深さの違いがカラー像として現出し, 3次元情報をカラー情報から得ることができた。また, 最少電離粒子に対して感度を有する原子核乳剤に3種類のカプラーを混ぜて, 3層に塗布したカラー原子核乾板を作製し, 粒子線を照射してカラー現像を行った。飛跡の深さの違いによる, 3色の発色が確認された。この手法の優位性と限界について原子核乾板における飛跡と比較して考察した。
