Evaluation of Post-license Advanced Driver Training in Italy
No full textAbstractPost-license advanced driver training addresses different categories of road users such as: novice drivers, professional drivers, company employers and recidivists. These training courses can be carried out on-track or on the road. On-track courses allow participants to gain knowledge on driving physics and experience limits in a safe road environment. On-road courses are more focused on hazard perception and situation awareness.Although extensive research has been done in this field, knowledge of the effects of these courses on road accident risk remains unclear. Previous evaluation of on-track courses did not always show a positive effect on crash rate. For example, post-license training focused on mastery of driving skills can lead to an increase of accident risk, especially on young males.However, research identified several factors that may enhance the effectiveness of driving training. In Europe a new framework for driver education and training has been proposed based on a safe driver hierarchical model (the GADGET model) and the development of a strategy for continuous learning.According to this framework, an evaluation study of on-track post-license advanced driver training has been undertaken in Italy with the main goal of assessing the safety effects of these courses and identifying training aspects to be improved. Besides crash rate, the study aims at assessing also driver behavior, knowledge of risks, self-evaluation and training quality.This paper presents the results of the possible effects of advanced driver training on driving behavior, considering in particular the number and type of violations. For each driver, data on age, gender and driving violations history were extracted from the platform and the national violations database.Three cases were addressed through a before-after analysis with control group. Case 1 considers all drivers who attended an ADT course. Case 2 aimed at understanding the effects of the courses on a specific target group: the traffic violators. Case 3 is similar to Case 2, however the control group was selected in a way that drivers characteristics and the violation rate was similar to the violation rate of the treatment group in the before period.The significance of the differences highlighted was assessed through appropriate statistical tests (i.e. paired t-test and the Wilcoxon signed-rank test).The study showed in general a higher propensity to commit traffic violations after attending an ADT course. These results are in contrast to what expected and show the necessity to diversify the training classes according to the different needs of participants
A methodology to assess pedestrian crossing safety
No full textPurpose: The safety level of a pedestrian crossing is affected by infrastructure characteristics and vehicular and pedestrian traffic level. This paper presents a methodology that allows assessing the safety level of a pedestrian crossing, regulated or not by traffic light, in an urban area according to the features of the crossing. Methods: A hierarchical structure representing factors influencing crossing safety has been developed and the relative contributions of each factor were calculated using AHP method. A composite index for crossing safety and specific indexes for main aspects included in the assessment have been developed. Results: Main assessment aspects are: Spatial and Temporal Design, Day-time and Night-time Visibility and Accessibility. Night-time Visibility resulted to have the higher weight (about 41%). Conclusion: Developed indexes allow ranking of pedestrian crossings and assigning intervention priorities, highlighting the aspects which are to be enhanced. The methodology has been used for the evaluation of 215 pedestrian crossings in 17 European cities for the Pedestrian Crossing Assessment Project co-financed by FIA Foundation. © 2010 The Author(s)
The Study of Katsumi Masuda’s Classical Literature Education Theory in 1950s
No full textIn this paper, I picked up Katsumi Masuda’s statement about clssical literature education. Through these statements, I point out something as below. (1) Masuda considered classical education as classical literature education. (2) Masuda considered classical education as human formation. (3) Masuda has students read the way of view and thinking of the author’s thing from the classical literature. (4) Masuda has students read the activity of the characters from the classical literature. (5) The background of Masuda’s idea was the cultural movement of the 1950s
Reading of papers for classics teaching materials research : Translating the “learning” of classical literature researchers into student “learning”
No full text 本研究は，古典文学研究者の論文の読解を通じて，学習者の「深い学び」に向けた教材研究のあり方を探究したものである。まず，学習者の〈学び〉について，次期学習指導要領で要請されているアクティブ・ラーニングを取り上げ，それをminds on の「深い学び」とするためには質のよい思考を引き出す“真正の「問い」”が必要である。それにもかかわらず現在の古典学習はhands on の活動主義に陥り，しかも古文教材の表層が辿られるだけ「考える」場面が用意されず，学習者の「深い学び」が成立していない状況について確認した。次に，竹村（1991）「宇治拾遺物語論－表現性とその位相－」を取り上げ，この専門科学〈研究〉者論文では，テキストへの“真正の「問い」”が先行研究のメタ的概観から選別，抽出され，その回答へのアプローチにおいて「深い学び」へと活用しうる視点と方法が開拓されていることを指摘した。こうした研究者の「真正な学び」を教材研究に活用することで，学習者の「深い学び」を構想する授業に必須の“真正の「問い」”の発掘も可能となる。本稿ではそうした竹村（1991）の有効性を検証し，あわせて汎用性を確認するために別テキスト教材（『徒然草』）の教材分析を試みた。This study explored ways of conducting teaching materials research for “deep learning” among students, through reading papers written by researchers of classical literature. First, “authentic ‘inquiry’” that draws out high-quality thinking is necessary for the “minds on” “deep learning” of active learning as required in the coming Courses of Study in student “learning”. In spite of this, it was confirmed that contemporary study of classics is falling into “hands on” activity centeredness, with opportunities for “thinking” ill-prepared and only traced on the surface of classics materials, so that students are not achieving “deep learning”. Next, using Takemura’s (1991) “A Study of Ujishui-Monogatari: A means to the representation”, it was pointed out that the specialist’s (researcher’s) “authentic ‘inquiry’” of text in the paper is selected and elicited from a meta overview of previous studies, and perspectives and methods that can be used for “deep learning” in the approach to responses are being developed. By using this kind of researchers’ “authentic learning” in materials research, it also becomes possible to unearth “authentic ‘inquiry’”, which is required in planning students’ “deep learning” in lessons. This paper investigated the effectiveness of Takemura (1991) and this kind of text, as well as conducting teaching materials analysis of another text, “Tsurezuregusa” to confirm versatility beyond a specific text
Strategies to enhance long-term competitiveness in the telecommunications industry : lessons for NTT
No full textThesis: S.M. in Engineering and Management, Massachusetts Institute of Technology, Engineering Systems Division, 2014.Cataloged from PDF version of thesis.Includes bibliographical references (pages 73-75).In the telecommunications industry, the market is highly global as well as competitive in this era of Internet and data communications. Telecommunications carriers compete with not only other telecommunications carriers providing broadband access and mobile communication but also network application and service providers, which are significant threats for telecommunications carriers. It is difficult for telecommunications carriers to control the market for two significant reasons. Firstly, due to the maturity of technology as well as customers, network services have become commoditized. Secondly, telecommunications network services are vulnerable to over-the-top services based on the Internet. This study aims to investigate how large telecommunications carriers can continue to be competitive in such an environment. This paper focuses on three kinds of strategic options that enable large high-tech companies to continue to make profits; internal R&D, growth and diversification, and M&A. In the second chapter the author focuses on IBM and Cisco, which are good examples of how large companies have evolved over time, combining these three strategies. Then, the use of the three strategies by major telecommunications carriers is investigated. Finally, in the fourth chapter, the author analyzes the future competitiveness of the NTT Group, the major telecommunications carrier in Japan, using these strategies within the next decade.by Shingo Kawai.S.M. in Engineering and Managemen
Widespread imiquimod-induced psoriasis like eruption: case report and analysis of mast cell infiltration.
No full textPsoriasis is an inflammatory skin disease that affects over 60 million adults and children worldwide.1 Many genetically innovative and easy-to-use models have been generated to study psoriasiform skin inflammation in mice. Topical application of imiquimod, the agent with immune response modifying activity, is widely used for psoriasis research. A Previous study demonstrated that mast cells (MCs) increase in imiquimod-induced psoriasis in mice.2 Topical application of imiquimod is used to treat actinic keratosis and condyloma acuminatum. Several cases of psoriasis-like eruptions caused by topical imiquimod have been reported. These eruptions are distinct from psoriasis. Moreover, psoriasis-like eruptions observed in areas other than the topical imiquimod site.3 Herein, we report a case of psoriasis like eruptions after topical imiquimod treatment. In previous studies, upregulation in the number and activation of MCs has been found in imiquimod-induced psoriasis in mice. 2 Mast cell infiltration has been found in patients with psoriasis.2 However, mast cell infiltration and the number of MCs in imiquimod-induced psoriasis in humans is unclear. We investigated the number of MCs in our case for a better understanding the mechanism of imiquimod-induced psoriasis like eruption.Tatsuya Katsumi, Ryota Hayashi, Shingo Takei, Manon Okamura, Yuka Tsutsui, Osamu Ansai, Akito Hasegawa, Yu Matsui, Tatsuya Takenouchi, Riichiro Abe, Widespread imiquimod-induced psoriasis-like eruption: case report and analysis of mast cell infiltration, Clinical and Experimental Dermatology, Volume 50, Issue 6, June 2025, Pages 1221–1224, https://doi.org/10.1093/ced/llae527This is a pre-copyedited, author-produced version of an article accepted for publication in Clinical and Experimental Dermatology following peer review.

Natronolimnohabitans, an organism living in soda lakes.The genus Natronolimnohabitans represents a currently monospecies alkaliphilic haloarchaeon inhabiting hypersaline soda lakes. Initially, the type species was placed in the genus Natronolimnobius mainly based on the phylogenetic relatedness inferred from the 16S rRNA gene sequence similarities. However, later on, it was reclassified to the current genus, Natronolimnohabitans, based on the results of more advanced phylogenomic analyses. Cells are rod-shaped and nonmotile. Gram-stain-negative, and red-pigmented. Obligate aerobic, and oxidase- and catalase-positive. Extremely halophilic with a growth Na+ range between 2.5 and 4.5M (optimum at 3.5 M). Cells lyse in less than 0.5M NaCl. Obligately alkaliphilic with a growth pH range between 7.5 to 10.0 (optimum at 9.5). Mesophilic or thermotolerant (optimal growth at 45∘C). Chemoorgano-trophic, utilizing mostly organic acids as carbon and energy source. The major polar lipids are diphytanyl (C20:C20) and phytanyl-sesterterpanyl (C20:C25) diether derivatives of phosphatidylglycerol (PG) and phosphatidylglycero-phosphate methyl ester (PGP-Me). The major respiratory quinones are MK-8 and MK-8(H2). Isolates have been obtained from soda lakes. DNA G+C content (mol%): 63.1 (HPLC), 64.3 (genome).
