In this paper, the authors make a hypothesis of a factor model to stimulate student group work and examine the model by conducting questionnaire surveys of undergraduate students who participated in a year-long project-based learning at the Scool of Network and Information, Senshu University. 511 students answered two surveys on their experience and feelings in the middle of and in the end of their project-based learning. Our findings are as follows: (a) some portions of our initial model are supported, (b) positive atmosphere in a group and good task management stimulate group learning activities. The results indicate that students should make opportunities to have convivial meetings and share recreational activities at astage in the formation of their groups. Furthermore, task management is an important element to stimulate their group work in the period of promoting their learning activities.

本研究課題は、睡眠中の記憶の固定および消去を司る神経基盤の解明を目的とする。研究に用いた記憶課題は漢字二文字からなる単語の記銘課題と再認課題からなり、再認課題は記銘課題直後と24時間後に実施した。被験者は記銘課題と24時間後再認課題の間に7時間の睡眠をとった。記銘課題では、100個の単語を被験者は記憶した。再認課題では、記銘課題中に提示された単語のほかに新たな単語50個が提示され、被験者は単語が記銘課題中に提示されたものかどうかをボタンで回答した。記銘課題および再認課題時の脳活動を機能的MRIにより計測した。記銘課題遂行中の脳活動について、再認できた単語の記銘に関わる脳活動を、直後再認によるものと24時間後再認によるものとで解析し比較した。その結果、直後再認でも24時間後再認でも再認できた単語に有意な活動が認められた領域として、右海馬、背側の下前頭回が同定された。また、直後再認で再認できた単語に有意な活動が認められず、24時間後再認で再認できた単語に有意な活動が認められた領域として左上前頭回、左中前頭回、腹側の下前頭回、左中側頭回、左右中後頭回、左舌上回、右海馬傍回が同定された。これらの結果から、「弱い記憶」の記銘には海馬および背側の下前頭回を含む領域の活動が本質的であるのに対し、それを「強い記憶」として固定するためには、それらの領域ほかに左上前頭回、左中前頭回、腹側下前頭回ほかの領域の活動が重要であると考えられた。24時間後再認時に正しく再認できたときの脳活動部位として両側海馬が同定された。この領域の活動の強さの解析から、活動の強さと睡眠の構造とに関係があることが示唆された。この結果から、睡眠により記憶の固定が起こり、その状態を再認時の脳活動として検出できることを示唆すると共に、Squireによる記憶の固定に関わる海馬-皮質系記憶システムの説を支持するものと考えられた。

The leaf phenology of Betula ermanii was observed in Shiga Heights, central Japan from 1985 to 2004. During this period, 5 birches were selected and their phenological traits analyzed using succes- sive automatic daily photography. The annual variation of mean temperature at this monitor station, specifically over the last 10 years, has become increasingly warm. According to observable facts, these birches have gradually tended to accelerate the time of leaf flushing and delay the time of leaf coloring. This process is indispensable in clarifying the effects of global warming on ecosystems while continuing similar monitoring in/for the future.

High-strength Al-Cu based alloy is a low-weldability material with many technical problems to be solved in order to improve its weld properties. This reseach was performed to evaluate various joining processes and determine a satisfactory process in terms of the properties of Al-Cu alloy sheet of 0.8mm in thickness. YAG laser, disk laser and plasma welding were considered as high-energy beam joining processes. Furhtermore, we also considered FSW which was classified as solid-state welding. The properties of high-strength aluminum alloy welds produced with high energy beam welding and FSW were satisfactory, and reliable welded joints with higher tensile strengths coule be obtained. When evaluating the weld characteristics in the drop impact test, the YAG laser and disk laser welded joints did not fracture along the joined line and the fracture chracteristics were satisfactory. FSW and disklaser welding displayed good properties, and it was evident that a reliable joint could be obtained by control of the heat source. In the case of FSW, the relationship between tensile and drop impact properties of the joints was not elucidated.

Aluminum is superior in lightness, corrosion resistance, a strength characteristic, property to being processed in comparison with other metal. In addition, I am used as a use of various fields by adding various addition elements, and in late years the consumption is a rise course as metal helping resource saving/energy saving. This article used 2107 sheet aluminum alloy which I put GTA welding, plasma welding, YAG laser welding, disk laser welding for and performed a tension test, drop test. And I weighed data 2017 which I demanded against a basic material and each welding method and clarified a mechanical property and a shock characteristic of a welding coupling. In addition, welding was stable by stack welding and used filler A5356-BY which there was for welding room because it was not possible. In addition, I matched the strength characteristic that I put a filler in and examined.

This survey was conducted to investigate students' independent study habits and activities after school. The questionnaire, which consisted of 18 items, was completed by 217 (68.2%) of 318 students in 1994. The results were as follows : 1) Most students studied less than one hour a day at home, and used most of that time to do their Special subject assignments. There were few students who studied at other schools (language school, etc.) and most students spent a lot of time doing part time jobs after school. 2) There were few students who read books for more than one hour a day and a lot of students who seldom read books ; especially Western books. They, however, often watched TV ; the time spent watching TV was more than three times the time spent reading books. Students were interested in employment or hobbies, but scarcely interested in lessons other than English subjects. 3) Many students were satisfied with school life, but one third of the first year students were not satisfied. The main reasons for being satisfied with school life were friends and interesting/beneficial subjects, and the main reasons for being unsatisfied were a lack of beneficial/interesting subjects or good teachers. These results suggest that there are few students who study independently and most students have not acquired independent study habits. The results also suggest that the quality of education and teachers are important for students to be satisfied with school.

Recently, many books on women in the Roman empire have been published in Italy. They, however, describe only prosopography of the famous women such as mothers, wives, and daughters of commanders, statesmen, and emperors. In this article, I will reconsider one of the most famous women, Livia who was the wife of Augustus. Tacitus emphasized Livia as the diplomatic mother of Tiberius as well as the faithful wife of Augusuts. By analyzing the portraits of Livia, I wish to reinterpret the image which Tacitus provided and to understand how she took part in the politics in the early Principate. I collected and analyzed seventy portraits of Livia, which have survived in Italy and other countries. I can classify these portraits into two main groups by examining the hairstyle as Italian "nodus" or "center-parted". Moreover, I classified them into several sub-groups, by evaluating when they were produced, as follows : Type A. after 38BC when Livia was married with Augustus. Bonn Akademisches Kunstmuseum ; Bologna, Museo Civico ; Paris, Louvre 622 ; Roma, Villa Albani 793 ; Padova, Museo Civico ; Paestum, Museo, Pesaro, Museo Oliveriano 3820 ; Stuttgart, Wurttembergisches Landesmuseum 3 etc. Type B. AD4 when Tiberius was designated the successor of Augustus. Kopenhagen, NyCarlsberg 615 ; Toulouse, Musee Saint-Raymond 3000 ; London, British Museum 1990 ; Hamburg, Kunstmuseum 1967 ; Cadiz, Museo Arqueologico ; Tarragona, Museo Arqueologico etc. Type B^1 and B^2. after AD14 when Augustus was dead. Ephesus, Museo Archeologico ; Cordova, Museo Arqueologico ; Leptis Magna : Volterram Museo Etrusco Guarnacci ; Musei Vaticani Laterano 1812 etc. Type C. Paris, Louvre 29 (Julia Augusta) ; Kopenhagen NyCarlsberg 616. Type D. Roma, Musei Capitolini ; Musei Vaticani sala dei Busti ; Musei Vaticani Laterano 10180. Type E. AD14 or AD19 when the type of "center-part" appeared. Kopenhagen, NyCarlsberg 618 ; Bochum Universtat Museum ; Luxemburg ; Kiel, Kunsthall ; Volterra Museo Etrusco Guarnacci etc. Type F. so called Salus Type, AD22 when Livia fell seriously ill. Pompei, Antiquarium ; Leningrad, Ermitage ; Bochum Universtat Museum. Type E^1. after AD29 when Livia died at 86 years old. Madrid, Museo Arqueologico ; Leptis Magna ; Paris Bibliotheque Nationale ; Atene, National Museum 325 ; Genova, Museo Civico. Type E^2. after AD41 when Livia was deified by Claudius. Kopenhagen, NyCarlsberg 617 ; Parma, Museo Archeologico etc. Type G. Kopenhagen, NyCarlsberg 614; 531; Napoli, Museo Archeologico. And there was another "nodus" type of the Claudian Age : Hague Cameo. As a result, I emphasize two points. Firstly, I can find a strong similarity among the portraits(type B-D)that were produced in abundance from the late Augustan age to the early Tiberian age. So, I say that the politics of the late Augustan age persisted into the early reign of Tiberius. In those days, statues of Livia were shown with those of Tiberius or her children, providing her image as a diplomat. Secondly, why did Claudius set up many statues of Livia? He was born in the famous family "the Claudius", the same family as Livia. He was not adopted into "the Julian", the family of the deified Augustus, although he was a predecessor, Tiberius and Caligula were adopted. Therefore Claudius looked upon Livia as an ancestor of his family and deified her as "Diva". Livia was very important for Claudius giving authority to himself and his family. And he regarded the marriage of Augustus and Livia as an important one, as the fact that the portraits of Livia were made in the old type(the Date of Augusuts)shows. Tacitus and Dio Cassius informed us of Livia's diplomatic efforts to certify Tiberius as the successor to Augustus. According to my research, however, I conclude that emperors made use of the images of Livia to justify their position as Princeps.
