The main objective of this research is to look for a difference on programming understanding between Graphic Designers, Game Designers and Programmers. We propose a method whereby comparing 2 displayed images and interactive animations produced by programming samples (problems) a subject decides which one of the programs is more difficult to build with programming than the other, or, if the difficulty is similar; to solve this problems, two types of understanding are needed: one regarding the visual processing of the two pictures, and the second regarding the program making those images. The problems of this method were built considering those two types of understanding. We built a testing system based on this method and performed an experiment using this system with three groups of students: Game Software (GS), Graphic Design (GD) and IT.The main objective of this research is to look for a difference on programming understanding between Graphic Designers, Game Designers and Programmers.

逆回し (back-in-time) デバッガはプログラムのトレース (実行履歴) を記録して過去の状態の参照を可能する機能を有しており,デバッグに於ける診断のあり方を根本から変える可能性を秘めている.しかしながらその機能を有効に活用するためには,作業者が膨大なトレースの中から適切な実行時点を指定し,その状態の正不正を判定しなければならない.こうした指定や判定は作業者自身のプログラム理解に大きく依存している.オブジェクト指向プログラミングはプログラムの再利用性や拡張性が向上させる反面,コードの理解を困難にする傾向が指摘されている.我々はこうしたオブジェクト指向プログラムに固有な問題を解決するために,外挿診断法 (diagnosis by extrapolation) という手法を提案し,それを実現する逆回しデバッガを開発中である.本手法は指定された時点の実行文脈を,作業者の既知の情報を用いて抽象化する事によって,問題解決を実現する点に最大の特徴を有している.本論文では実用的なプログラムのデバッグ事例を通じて逆回しデバッガが実装すべき機能と手法の有効性の評価方法を考察する.

一. 道徳それ自体に対する考え二. 道徳性(la moralité)の分析E. Durkheim's "L'Education Morale" is the lecture in the primary course on the Science of Education which he had delivered in the Sorbonne, in 1902-1903. The lecture consists of Introduction and two parts. Intending to establish the moral education on the basis of secular morality in the introduction, he proposes, "When we attempt to secularize the moral education, we must discover moral forces, release them from religious symbols, and explain them in terms of rationality. In rationalizing morality, we must not loose some of its component elements, but we must enrich it with new elements." In the first part of the lecture, he analyzes the secular morality and points out its three elements: "l'esprit de discipline", "l'attachement aux groupes sociaux" and "l'autonomie de la volonte". Symmetrically to the first part, the second part comprises three sections: "sur l'esprit de discipline", "sur l'esprit d'abnegation" and "sur l'autonomic de la volonte", studied primarily from the pedagogic viewpoint. We may be able to look into the basic problems in his sociology through the study of his sociological approach to the moral education.

1) 問題の所在2) ルソーにおける自然と社会3) デュルケームにおける教育と社会4) 結語最近におけるルソー関係の主なる解説・批判書あとがきD'abord, mon sejour de deux ans du 1^er avril 1981 au 24 mars 1983, a Geneve, Suisse, a Bordeaux et a Epinal, France, s'est bien passe grace a l'amabilite des gens qui habitent ces trois villes. Mes remerciements vont en particulier a M. le Maitre Ch. OCHSNER et a ses proches, a M. et M^me H. BRAND, a M. et M^me M. L. DUFAUX, a M. et M^me Ch. HEIDSIECK, a M^me C. HONDA, a M^me N. PERRET, aux professeurs a l'Universite de Geneve : MM. Ch. LALIVE d'EPINAY, P. FURTER, R. GIROD et J. KELLERHALS, aux professeurs a Universite de Bordeaux II : M M. J. WITTWER, H. BOIRAUD, M. BROSSARD et F. CHAZEL, a M. le Professeur R. JAVELET a l'Universite de Strasbourg, a M. le professeur M. MAFFESOLI a l'Universite de Paris V, et enfin a M. T. TODOROVIC au Japon, pour leur aide et leurs conseils. On sait que Rousseau a ete un des grands penseurs sociaux du XVIII^e siecle et que Durkheim a ete lui aussi un celebre sociologue au debut du XX^e siecle. Puisque leur situations historiques et sociales ont ete tres differentes, on ne peut pas simplement comparer la pensee de Rousseau avec celle de Durkheim. Neanmoins, quand on considere en profondeur la pensee fondamentale des deux grands penseurs, on y trouve un point commun : c'est leur conscience de crise de leurs epoques respectives. Il y a un petit lac sauvage appele Bienne au nord de la ville de Geneve. On y trouve une ile tres fine et longue a l'instar d'une peninsule. C'est l'ile de St.-Pierre. Dans cette ile se trouve un hotel ancien. Une fois je m'y suis rendu en compagnie de mes amis genevois. Nous avons trouve au premier etage les deux chambres oa Rousseau avait ecrit autrefois "Les Reveries du Promeneur Solitaire". C'est alors que nous nous sommes rappeles le visage et l'oeuvre de Rousseau et que nous avons eprouve le sentiment du respect pour les lieux. Par ailleurs, lors de mon sejour a Bordeaux et a Epinal, je pensais souvent a Durkheim en flanant tout seul dans les belles rues de ces vieilles villes francaises. Cet essai consiste en quatre chapitres suivants : 1) quel est le sujet de l'essai ? 2) les concepts de Nature et de Societe chez J.-J. Rousseau. 3) les conepts d' Education et de Societe chez E. Durkheim. 4) conclusion.

Renewable energy sources such as photovoltaic generation (PV) have been promoted to be innovated. However, the output of PV is influenced by the weather condition and cause a steep fluctuation. So it is important to forecast the output of PV when an electric power company makes the power supply schedule for demand. In this paper, the authors proposed a forecasting method for amount of insolation closely related to the output of PV. In the proposed method, the amount of insolation is forecasted through the application of Genetic Algorithm which is one of the optimization method by using the past measured data. In addition, the correlation coefficients are analyzed with the weather data and measured insolation data. And, the correlation coefficients are used as the weight of observe value. The authors verify the validity and prediction accuracy of the proposed method. Moreover, we tried to improve the forecasting error by using the latest measured weather data and weather data of the other point.

The effects of L-carnitine on ventricular arrhythmias were evaluated in dogs with acute myocardial ischemia and a supplement of excess free fatty acids (FFA). Acute myocardial ischemia was induced by ligation of left anterior descending coronary artery. After 80 minutes of coronary occlusion, high plasma FFA was induced by intravenous injection of heparin 200 u/kg and Intralipid(R) 5 ml/kg as a bolus. After additional 60 minutes, beating hearts were removed from animals and tissue levels of free carnitine, short and long chain acyl carnitine, FFA and adenosine triphosphate (ATP) were determined. L-carnitine 100 mg/kg was administered intravenously 5 minutes before coronary artery ligation. Electrocardiograms were recorded continuously by a Holter electrocardiographic recorder during the experiment and ventricular arrhythmias were quantified by an arbitrary scoring system. In ischemic and excess FFA supplemented myocardium, free carnitine and ATP decreased, whereas long chain acyl carnitine and FFA increased. And these metabolic changes tended to be reduced by L-carnitine. Pretreatment of L-carnitine also reduced the grade of ventricular arrhythmias induced both by acute myocardial ischemia and by supplement of excess FFA. These results suggest that the administration of L-carnitine may be beneficial to prevent serious arrhythmias in ischemic heart disease, presumably by restoring the impaired FFA oxidation.

The effect of L-carnitine on cardiac hemodynamics was evaluated in normal closed chest dogs. Extracorporeal circulation was produced to measure coronary blood flow in closed chest dogs. Coronay venous blood was introduced to the extracorporeal circuit through a polyethylene catheter wedged into the coronay sinus under fluoroscopic control and was returned to the animal through the left jugular vein. L-carnitine was infused intravenously at a constant rate of 80mg/Kg/min for 8min. Hemodynamic responses appeared within 1 to 3min of carnitine infusion and peak effects were observed nearly after 5min. Peak effects on cardiac hemodynamics after 5 to 8min of carnitine infusion were as follows. Heart rate decreased by 17% from control (p<0.05). Aortic and left ventricular pressure increased by 20% (p<0.05 and p<0.01 respectively) and peak positive left ventricular dp/dt increased by 35% (p<0.01), the mean rate pressure product as the index of myocardial oxygen consumption remained unchanged. Coronary blood flow increased by 60% (p<0.001) and coronary vascular resistance decreased by 25% (p<0.01). As the infusion of carnitine was discontinued, the effects promptly disappeared. These data suggest that L-carnitine has direct vasodilating and positive inotropic effects on cardiovascular system.

This research focuses on Eco-cooking, an environmentally-friendly way of cooking through shopping, cooking and cleaning. We analyze and quantify people's energy-saving behaviors, evaluate the effect of eco-cooking, and seek to clarify what kinds of energy-saving behaviors have or have not been promoted by energy-saving education. The three-year-research on third-year students in home economics teacher-training program shows reduction in gas, water usage and waste produced during cooking by 40% to 80%. CO2 emission amount also decreased by about 50%. Furthermore, survey shows people who sometimes or always perform energy-saving behaviors account for 75% of the total. In conclusion, Eco-cooking energy-saving education is generally effective in raising people's energy-saving awareness and inducing behavior change. In order to make limited energy-saving educational programs more effective, it is important to ponder upon the content that is suitable for such a program as well as what the program should focus on.
