問題解決型のソフトウェア開発演習は,与えられた課題に対するゴールまでの道筋を学生自身が探し出し,解決を目指すグループ演習である。グループごとに開発の進め方や解決方法が異なるため活動状況が見えにくく,グループの能力差によって指導方法も大きく異なる。本研究では,「活動状況」「グループ特性」「課題」の3つの見える化を演習に取り入れることでそれらの問題を解決し,学生のやる気を引き出す「見える」ソフトウェア開発演習を実現する。本稿では演習に取り入れた見える化の工夫について述べるとともに,平成18年度と平成22年度に難易度を変えて同じ課題を実施した演習結果について評価を行う。

Interest in a science and technology career, and determinants of such interest, were investigated. In Study 1, self-efficacy for work activities and interest in a science and technology career were assessed. Participants were undergraduate students (n = 264; 132 men, 132 women) and graduates (n = 276; 146 men, 130 women). Graduates were more interested in a science and technology career than undergraduate students, and men were more interested in a technology career than women. Moreover, self-efficacy for realistic and investigative activities was positively related with interest in such a career. In Study 2, relationships between self-efficacy for realistic and investigative activities and childhood experiences were investigated using data from undergraduates (n = 262; 132 men, 130 women) and graduates (n = 274; 141 men, 133 women). Individuals who frequently experienced daily activities, activities in nature, and activities with animals and plants in their childhood had higher self-efficacy for realistic and investigative activities. Moreover, graduates had such past experiences more frequently than undergraduates and males more frequently than females.

既存の雑多で構造の不均質な情報源から情報を収集・整理する手法を提案する.基本となるアイデアとして,雑多な情報をゆるやかに関連づける連想構造というデータ構造を用いる.連想構造は生データから容易に生成でき,人間が直観的に理解しやすい.我々は,連想構造を用いて既存の情報源から情報を収集し,整理する過程を支援するシステムCM?2(Contextual Media version2)を試作した.CM?2では,(a)既存の情報源から情報を取り込み,連想構造を生成する情報キャプチャ機構と,(b)キーワードに基づき情報の切り出しと構造化を行う知的情報統合機構を実現した.CM?2の有効性を実験によって確かめた.We propose a method to gather and reorganize information from heterogeneous information sources.The method is based on the use of a plain information representation called associative structures.Associative structures connect various information media without defining the semantics rigorously.They are easy to generate from raw data and comprehensible to humans intuitively.We developed a system called CM-2(Contextual Media version 2) to realize this method.We describe the system's two major facilities;(a) an information capture facility which gathers information from heterogeneous information sources and generates associative structures and (b) an intelligent information integration facilitywhich reorganizes information according to user's input.We verify our approach by analyzing results of experiments.

We reveal the eruptive history of the Higashi Izu monogenetic volcano field by tephrochronology and loess-chronometry and describe mainly volcanoes older than 32,000 years ago. The eruption of the volcano field started at about 150,000 years ago. Twelve tephra from volcanoes outside the Izu Peninsula were used as key beds. We found four eruptive fissures ; Takatsukayama-Sukumoyama, Kadono-Umenokidaira, Koike-Oike, and Numanokawa fissures, along each of which two to five monogenetic volcanoes erupted simultaneously. Interbedding of a distal wide spread tephra between eruptive deposits proper to the volcano field (the KIP-4 pumice between the Takatsukayama-Sukumoyama tephra, and the Hakone Da-4 pumice between the Kadono-Umenokidaira tephra) means that an eruption of a volcano outside the Izu Peninsula occurred simultaneously with the eruption of the volcano field. Vent locations of the volcano field were limited to the northern half of the present distribution during 80,000-150,000 years ago and were expanded in the later stage. Average frequency of eruption in the volcano field is calculated to be one/7,900 years for the period of 40,000-150,000 years ago, and one/2,500 years for the past 40,000 years. Average discharge rate of magma is calculated to be 0.64 kg/s before 40,000 years ago, and 2.5 kg/s for the past 40,000 years. Thus, both the average frequency of eruption and the magma discharge rate are higher for the past 40,000 years than those in the earlier stage. Many of the eruptions of andesite magma occurred later than 14,500 years ago, and the ones of dacite-rhyolite magma occurred only for the past 3,200 years. The cumulative pattern of the discharge mass of magma from the whole volcano field against time shows no clear predictability.

Successive terrestrial coverbeds called "volcanic ash soils" are widely distributed in Japan. In this paper, the origin of parent material of volcanic ash soils is discussed from the stratigraphy and the mineralogy of volcanic ash soils to clarify the accumulation of volcanic ash soils. In the Hakkoda Mountains and in the southern part of Tokachi Plain, thickness of tephra interbeds recognized within peaty soils are almost the same as those within the volcanic ash soils. No more distinct tephra interbed is observed in the volcanic ash soils with the exception of the marker tephra interbeds. This fact indicates that the accumulation of the volcanic ash soils have occurring through the periods without tephra deposition. Moreover, the existence of soil developed on the latest Hokkaido-Komagatake tephra of 1929, also suggests that the accumulation of volcanic ash soils is almost independent of the tephra deposition. Mineralogical composition of the fraction coarser than 0.02 mm in the volcanic ash soils are mainly derived from the underlying tephra interbeds. On the other hand, the finer fraction contains amorphous clay minerals and non-volcanogeneous materials such as quartz and illite. The former is weathering products of tephra and the latter would be derived from eolian dust. In particular, several studies on oxygen isotope composition have revealed that the origin of fine quartz is the eolian dust. Accumulation rate of fine materials in the volcanic ash soils ranges from 10^<-1> to 10^0 mg cm^<-2> y^<-1>. It agrees well with those of paleosols intercalated into sand dunes along the coast of the Japan Sea, of pelagic sediment of the Japan Sea, and of eolian dust fall calculated from atmospheric dust density. From the evidence mentioned above, parent material of volcanic ash soils is originated from the reworked materials of tephra with the fine materials of the eolian dust.

Sedimentological study of the recent deposit of Sakurajima Volcano has exposed some properties of the deposit accumulated by small-scale eruptions. Fall-out deposit of long-term such eruptive activity occur in any nearly concentric circular area around the source. Change of the small-scale eruptive activity manifests as the facies, bulk density and carbon content of the deposit, because such characters of the deposit are reflections of the accumulation rate of pyroclastics. Gray laminated or massive volcanic sand layer indicates a period of highly active volcanism ; brownish loamy volcanic sand layer a less active one and brownish loam or humic soil a dormant or inactive one. The duration of those periods can be estimated from the facies, thickness and bulk density of the deposit and recent fall-out ash data.

Vygotsky is a psychologist who eagerly worked on the research and the practice of education for children with difficulties. His theory is pioneering, and it has a big influence on modern education for children with difficulties. In this paper, the following two problems are examined. The first is how the theory of Vygotsky is located in the present special needs education research, and the next is how it is useful for the research of the special needs education of Japan. The concept of "detour" is presented as a clue effective to research the special needs education of the mainstream school.

北関東喜連川丘陵の早乙女において,関東ローム層中に含まれる微細石英の堆積速度の最近約10万年間の変動を検討した.微細石英のほとんどは,広域風成塵として冬季の北西モンスーンによって中国大陸より運搬され,日本列島に堆積する.したがって,その堆積速度の変動は冬季の北西モンスーンの強度の変動を示唆する.早乙女における微細石英の堆積速度は,SPECMAPによる酸素同位体比変化から,寒冷とされるstage 2,stage 4,stage 5bに対比される時期に高い値を,温暖とされるstage 1,stage 3,stage 5aに対比される時期に低い値を示した.このことは,寒冷なstageには北西モンスーン強度が増大し,温暖なstageには減少したことを示す.この結果は,中国大陸黄土高原における黄土-古土壌シークエンスの諸性質の分析かち明らかにされている北西モンスーンの強度の変動の結果と一致する.

We construct energy-independent but nonlocal potentials above inelastic thresholds, in terms of Nambu-Bethe-Salpeter wave functions defined in quantum field theories such as QCD. As an explicit example, we consider NN→NN+nπ scattering processes for n=0,1,2,…. We show the existence of energy-independent coupled channel potentials with a nonrelativistic approximation, where momenta of all particles are small compared with their own masses. In the case of two-body inelastic scatterings such as ΛΛ→ΛΛ, NΞ, ΣΣ, on the other hand, we show that energy-independent potentials can be constructed without relying on nonrelativistic approximations. We also propose a method to extract these potentials using time dependence of general correlation functions.
