Onion (Allium cepa L.) is one of the most important vegetable crops in the world, and its cultivation is roughly divided into two types: autumn- (overwinter) and spring-sowing. In this study, we compared the changes in plant growth and bulb development of four short-day and intermediate-day onion cultivars under two years of varying environmental conditions to understand autumn-sowing cultivation and growth characteristics. A comparison of the growth parameters of the four cultivars throughout the growth period revealed that the increase in total leaf number and area, and plant height were almost completely inhibited in winter. In spring, these growth parameters increased rapidly in the early maturing cultivars and reached a plateau depending on the cultivar’s maturity type, as previously shown in spring-sowing cultivation. It is known that AcFT1 and AcFT4 play a key role in the bulb development of cultivated onions. Therefore, we conducted expression analysis of these genes for the four cultivars grown in the field and confirmed that AcFT1 was expressed following the maturity, irrespective of cultivation methods. We also analyzed AcGI expression in leaf blades, and a certain relationship between changes in bulb development and AcGI expression was observed. Correlation analysis of AcFT1 expression and total leaf number and area was conducted, and strong positive correlations were observed. In conclusion, our study demonstrated genetically that leaf number and area are important for inducing onion bulb development.

Akebia trifoliata is cultivated locally in few areas of Japan. Artificial pollination is considered indispensable for stable fruit production, as Akebia spp. exhibit self-incompatibility (SI). However, little is known about the reproductive physiology required for effective artificial pollination. In this study, we investigated the effects of self-pollen contamination on the fruit set of ‘Fuji Murasaki’ (A. trifoliata), one of the main lines in Yamagata Prefecture, Japan. Both the self- and cross-pollen tubes reached the base of the ovary and penetrated the ovules at 10 days after pollination, indicating that A. trifoliata exhibits late-acting SI. Self-pollination one day before cross-pollination completely inhibited fruit set, while self-pollination one day after cross-pollination did not inhibit fruit set in both 2016 and 2020, indicating interference in cross-pollination by self-pollen contamination. Fruit set rates for artificial pollination using a 1:1 mix of self- and cross-pollen were significantly lower than those that used non-contaminated cross-pollen in both 2016 and 2019, but were comparable when using a 1:1 mix of lycopodium powder and cross-pollen. The seed number of fruit resulting from mixed pollination was not significantly lower than that of fruit resulting from cross-pollination. Interestingly, 1:1 mixed pollination of self- and cross-pollen sometimes yielded abnormal fruits with an apex that remained pale and did not soften. These results suggest that excessive self-pollen contamination in artificial pollination may not be desirable for A. trifoliata fruit production.

本研究の目的は、専門サービス組織の組織成長の要因と過程を明らかにすることである。すでに触れたように、組織の成長は時間的変化を持つ多面的な現象であるため、この答えを導くには、定量および定性研究を併用する必要がある。Penroseの理論を援用すれば、組織成長の要因と過程を明らかにするためには、インタビューなどの質的研究を通して当事者の機会の認識や経営資源の使い方の意思決定を分析する必要がある。この点について、本研究では、営利企業ではなく、専門サービス組織を対象とするため、既存研究の境界条件が明らかにできる。

Positive identification of unknown skeletonized victims lacking clinical records generally difficult. However, if their facial photographs could be obtained, their unknown skulls could be identified by the cranio-facial superimposition. The last two decades, video superimposition technique has widely been used for identifying unknown skulls. Although video superimposition will be the most superior technique, the means are expensive and unusual installation. Therefore, in Japanese local forensic science laboratories, the video superimposition installation is not popularly used. To solve the problem the authors attempted to identify an unknown skull by an inexpensive means of superimposition using a personal computer, a digital camera, an image-scanner and a photo-retouch-soft(Adobe Photoshop). The use of the personal computer with Adobe Photoshop allowed to capture a digitized image of the facial photograph with the image-scanner and an image of the skull with the digital camera. With the Adobe Photoshop, the digitized skull's images can be converted to a transparency so as to be overlaid on the digitized facial image and then be adjusted to their respective size. In order to investigate the reliability of our cranio-facial superimposition method, one skull was superimposed on facial photographs of the true person and 14 other people. The true person was correctly identified as the skull's owner and the 14 others were excluded. Hence, the authors insist that this method will be useful to demonstrate the consistency between skull and facial photograph for personal identification.   The application of this superimposition method to three actual cases was also described.

This article constitutes a review of the literature and an evaluation of the anatomical relationships between skull and face including the soft tissue thickness at various anthropometrical points of the skull, along with a comparison of the methodologies involved in the three techniques, that is, photographic, video and computer-assisted superimposition techniques used in forensic science. In addition, an evaluation of cosistency between skull and face is discussed from the aspect of personal identification.   Forensic examiner must be well versed in the anatomy of skull and face for effective utilization of the superimposition technique. When evaluating anatomical consistency between these parts, special attention should be paid their outline, the facial tissue thickness at the anthropometrical points, and positional relationships between skull and face. Data on the thickness of facial soft tissue has been accumulated for each race, Caucasoid, Negroid and Mongoloid. The positional relation of the eyebrow and eye to the orbit, the ala to the nasal aperture, and the lips to the teeth has been investigated by many researchers.   Over the last two decades, video superimposition technique has widely been used for identifying unknown skull. The video superimposition presents enormous advantage over the conventional photographic superimposition. This technique allows the fade-out of either the skull or facial image on the monitor for overall assessment of how well the two images match. This also allows the various sectioning images of the skull and facial images for evaluating the positional relationships between the skull and face. In this technique, however, the anthropometrical examination including soft tissue thickness could not directly be performed on the TV monitor.   On the other hand, in the last ten years, the computer-assisted cranio-facial superimposition has been developed. The use of a video-computer with appropriate software allows to take the images of the skull and facial photograph with only one camera and to directly compare the digitized both images on the monitor. The computer technology has also been used to determine the size of natural head and optimum objective length. The software such as the polynomial functions and Fourier harmonic analysis has been applied to evaluate the fit between the outline of skull and facial photograph.   It is suggested that the outline from the forehead to the gnathion in the lateral or oblique view is the preferable portion for personal identification, and the cranio-facial superimposition method is reliable for personal identification when two or more facial photographs taken from different angles are used in the examination. The computer-assisted skull identification system using video superimposition is useful to demonstrate the cosistency between skull and facial photograph because the quantitative data including anthropometrical measurements obtained from this system provide objective and reliable results in skull identification.

This study aimed to clarify the exercise intensity of the motor learning scenes in elementary school physical education class. The subjects were 28 children (16 boys and 12 girls) in the 5th grade. We examined all five exercises of long jump, physical expression, tag rugby, hurdle run and tee ball. Lifecorder GS (SUZUKEN Co.,Ltd.) was used to measure exercise intensity. The results of the analysis showed a significant difference in exercise intensity among individuals. The analysis revealed difference in exercise intensity between tag rugby and tee ball, between tag rugby and long jump, and between physical expression and long jump (p<0.05). About differences among the average of exercise intensity in exercise, hurdle run was significantly higher than tag rugby, physical expression, and tee ball, and the long jump was significantly higher than the tee ball(p<0.05). In each exercise, the proportion of motor learning scenes was 75.4%, 70.7%, 62.8%, 58.0%, and 43.9%, for tee ball, physical expression, long jump, hurdle run, and tag rugby, respectively. These findings suggest that exercise intensity did not increase when motor learning scenes were secured. The incorporation of high-intensity activities in exercises with low exercise intensity may be necessary.

本研究は、筆者が担当する大学での理科教育法及び地学に関する教養の授業を学ぶ学生のデータに基づいたミスコンセプション研究から生まれた問いのデザインが、義務教育から高等学校の地学分野の教育、さらに一般市民の気象防災にどのような効果をもたらすのかについて、大学の授業における試行をもとに分析したものである。その際、まず中学校の教科書の記述や模式図がどのようなミスコンセプションを生起させているのかについて分析し、特に、大雨などの気象災害を学ぶことができるような内容になっているのかを検討した。その結果、前線についての説明や模式図、気象災害の中心となる積乱雲についての記述、降水域を記した模式図は、近年多発する大雨などの降水域とはあまり整合しておらず、気象防災知識を学ぶには不十分なのではないかとの結論を得た。この状況を改善するためにミスコンセプションから開発した問いのデザインの効果について報告する。

吸引通気式発酵処理の排気中のNH3は圧送通気式に比べ高濃度となり, 新たな脱臭方法を検討する必要がある。モミガラにリン酸を1:0.5, 1:1.0, 1:1.5, 1:2.0, 1:2.5の比率で添加した材料を回収資材 (吸着材) に使用し, 高濃度アンモニアの脱臭および回収実験を行った。直径約15cmの円形吸着槽に回収資材を50cm (堆積高さ) 充填し, 4000ppmのアンモニアガスを通気した場合, 吸着時間は約28時間で, 回収資材1kgのアンモニア吸着量は159gN (1:2.0) であった。これは添着炭の約2.6倍, ゼオライトの約23倍の吸着量に相当した。吸着操作後の回収資材はpHから推察すると, リン酸二水素アンモニウムとリン酸水素二アンモニウムがモミガラに付着したものと考えられる。吸着操作後, 回収資材からのアンモニアの再揮散は放置期間中気温30℃を超えた日数に関係が見られたことから, アンモニアの再揮散と外気温との関係について, さらなる検討が必要であった。
