Consideration of Science Education in Japan in the 21st Century

理科教育のあり方について4つのことを提言した、(1)第2次世界大戦後、豊かになりたいという明確な学習の動機付けがあったが、豊かな社会になるにつれてさまざまな教育に関する問題が生じている。学校だけが努力してもこどもを健全に育てるには限界がきているだろう。これからの学習指導は学校が中心であることには変わらないが、社会が学校教育をサポートする環境づくりが必要である。(2)高等学校では、校内研修に取り組む体制を確立することや「教える内容」ばかりでなく「教える方法」に研修に力を入れることが求められる.(3)大学や高等学校では、社会で必要とされる「コミュニケーション能力」「問題解決・分析能力」「企画創造力」「データ処理・事務処理能力」などに教育の重点を置くべきである。(4)小中学校では、総合的な学習の時間を設けないで、基礎基本の定着に重みを置き、必要に応じ考える力や学び方・調べ方等の能力の育成を各教科の授業の中で行うべきである.Article信州大学教育学部附属教育実践総合センター紀要　教育実践研究 2: 65-75(2001)departmental bulletin pape

BASIC EXPERIMENTS OF CS UPTAKE CAPABILITY FOR Eleocharis acicularis

Soil in the Fukushima area has been polluted with the radioactive contaminants such as Cs by the accident of Fukushima Daiichi nuclear power plant in March 2011. Remediation of soil contaminated with radioactive Cs remains one of the most important problems. Phytoremediation is an environmental remediation technique that takes advantage of plant physiology and metabolism to remove radioactive contaminants. Eleocharis acicularis is well known as heavy metal hyperaccumulator aquatic plant and expected as the strong candidate for application to Phytoremediation of polluted water and soil. In this study, a laboratory experiment was carried out to investigate the potential of E.acicularis for Phytoremediation of radioactive Cs contaminated site.The plants were grown hydroponically and placed in solutions containing Cs and K at different concentration (Cs concentration: 5 mg/L, K concentration: 0, 0.2, 2, 5, 50, 100 mg/L) in a period of 21days.In the experimental results, the highest concentration of Cs was 1560 mg/kg-DW in E. acicularis after 21 days. The concentration of Cs in plants decreased with the increasing initial concentration of K in the solution. This results indicate that E. acicularis has the ability to accumulate radioactive Cs from radioactive Cs contaminated soil and water, making it a good candidate species for radioactive Cs Phytoremediation. Keywords : Fukushima, Eleocharis acicularis, phytoremediation, C

Vertical Temperature Profiles with Light Breezes at Night in Urban and Rural Areas of Obuse, Nagano

This paper describes the vertical structure of the nocturnal heat island in a small town. Tethered balloon soundings were conducted 180 times in and around an urban area on nights with light winds from March 2003 to May 2005. Surface inversions developed not only in rural areas but also in urban areas. Surface inversions developed quickly after sunset at the rural site, whereas development was slower at the urban site. At six hours after sunset the verticaltemperature profile in the urban area was the same as that in the rural area. Heat island formation in the small town was related to the delay in the development of surface inversion in the urban area. The crossover effect can be seen in only three of 23 surveys for which vertical soundings were performed in both urban and rural areas

The Relationship between Urban Surface Indices and Heat Islands in High and Low Building Areas

During 2003, temperature distributions were observed 69 times in two types of residential areas in Imaihara, Nagano Prefecture, Japan. Both high and low building areas were warmer than the rural area at night. But a cool island appeared only in ihe high building area in the daytime, lhe maximum nocturnal heal island intensity occurred not at a calm condition but at the wind speed of about 1 m/s. In addition the wind speed in which the maximum heat island occurred in the high building area was larger than that in the low building area. The urban surface indices of the high and low building areas showed only small differences in the sky view factor and building/land ratio but large differences in the floor-area ratio. Floor area ratio related to heat island formation in this area

Non-resonant global mode in LHD partial collapse with net toroidal current

A transition from an interchange mode to a non-resonant mode is found in the nonlinear magnetohydrodynamic simulation for the partial collapse in a large helical device (LHD) plasma with a net toroidal current. This transition can occur when the magnetic shear is weak and the rotational transform is close to unity in the core region. In this transition, the mode number of the dominant Fourier component is reduced. As a result of the nonlinear evolution, the (m, n) = (1, 1) component can be dominant, where m and n are the poloidal and the toroidal mode numbers, respectively. This transition is considered to be a candidate to explain the observation in the LHD experiments with the net toroidal current that show partial collapses are caused by the (1, 1) mode

MT-ND5 Mutation Exhibits Highly Variable Neurological Manifestations at Low Mutant Load.

Mutations in the m.13094T>C MT-ND5 gene have been previously described in three cases of Leigh Syndrome (LS). In this retrospective, international cohort study we identified 20 clinically affected individuals (13 families) and four asymptomatic carriers. Ten patients were deceased at the time of analysis (median age of death was 10years (range: 5·4months-37years, IQR=17·9years). Nine patients manifested with LS, one with mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS), and one with Leber hereditary optic neuropathy. The remaining nine patients presented with either overlapping syndromes or isolated neurological symptoms. Mitochondrial respiratory chain activity analysis was normal in five out of ten muscle biopsies. We confirmed maternal inheritance in six families, and demonstrated marked variability in tissue segregation, and phenotypic expression at relatively low blood mutant loads. Neuropathological studies of two patients manifesting with LS/MELAS showed prominent capillary proliferation, microvacuolation and severe neuronal cell loss in the brainstem and cerebellum, with conspicuous absence of basal ganglia involvement. These findings suggest that whole mtDNA genome sequencing should be considered in patients with suspected mitochondrial disease presenting with complex neurological manifestations, which would identify over 300 known pathogenic variants including the m.13094T>C
