Le formalisme de la méthode K. K. R. (Kohn, Korringa et Rostoker) a été développé pour les cristaux complexes (plusieurs atomes par cellule élémentaire du cristal. L'approximation d'un potentiel central ("muffin-tin) a été adopté et de là a été évaluée la fonctionnelle de Kohn et Rostoker pour arriver aux éléments du déterminant séculaire. L'adoption du groupe spatial de symétrie du graphite type hexagonal a permis le calcul des distances des proches voisins à un atome donné de la cellule du cristal du graphite. Il a été systématiquement procédé au calcul de l'ensemble des éléments du groupe ponctuel du graphite et de là a été calculé l'ensemble des fonctions de base symétrisées pour tous les points et directions de symétrie de la première zone de Brillouin. Après l'évaluation des coefficients de Gaunt il a été donné une méthode analytique et numérique pour le calcul des coefficients de structure de HAM et SEGALL. Il a été mis en oeuvre également une réduciton importante du travail d'analyse numérique et du temps de calcul. Les fonctions d'ondes ont été analytiquement et leur forme finale a été donnée sous forme de combinaisons linéaires d'harmoniques sphériques de même 1 pour tous les groupes du vecteur d'onde de la première zone de Brillouin<br>We choose the K. K. R. Method to perform a formalism of band structure calculations. We then use the muffin-tin approximation to evaluate the KOHN and ROSTOKER'S fonctionnal of complex cristals (more than one atom per unit cell). We use the hexagonal structure of graphite and perform all calculations about the symetry of this structure and, use the criteriums of symmetry theory to calculate all the symmetried basis functions along the BRILLOUIN zone. We give an analytical and numerical method for the calculation of the structure coefficients of HAM and SEGALL. We use too the basis functions to developp a reduction of the numerical analysis and time calculation. We finally give the expressions of wave functions of graphite in term if linear combinations of spherical harmonics with the same quantum number 1, this is done for all irreductible representations of all the symmetry groups of wave vector

Cette thèse porte sur l'étude des cocycles quasi-périodiques à valeurs dans des groupes de Lie compacts semi-simples. Nous nous restreindrons au cas des cocycles à une fréquence. Nous démontrons que, pour un ensemble de mesure de Lebesgue pleine de fréquences, l'ensemble des cocycles $C^{\infty }$ qui sont $C^{\infty }$-réductibles sont $C^{\infty }$-denses. Le premier pas sera l'obtention de deux invariants de la dynamique, qu'on appellera énergie et degré, qui distinguent en particulier les cocycles réductibles des cocycles non-réductibles. On entamera ensuite la démonstration du théorème principal. Nous démontrons dans un second temps qu'un algorithme dit de renormalisation permet de ramener l'étude de tout cocycle à celle des perturbations de modèles simples indexés par le degré. Nous analysons ensuite ces perturbations par des méthodes inspirés de la théorie K.A.M.. En particulier, nous démontrons qu'un cocycle $C^{\infty }$ mesurablement réductible à une constante diophantienne est alors $C^{\infty }$-réductible.

L’obiettivo di questa ricerca è quello di confrontare i dispositivi di sicurezza militare delle colonie italiane e inglesi in Africa Orientale nel periodo 1924-1939. Oggetto della ricerca saranno le truppe coloniali indigene, gli ascari/askari, di Eritrea e Somalia per quanto riguarda l’Italia, e di Somaliland, Kenya, Uganda, Nyasaland, Tanganika e Sudan per quanto riguarda la Gran Bretagna. Tale contesto cronologico e geografico non ha ricevuto molta attenzione dalla storiografia se lo si guarda da un’ottica regionale e trans-coloniale. Inoltre, alcuni corpi militari sono stati letteralmente trascurati da entrambe le storiografie, nella fattispecie quelli delle due Somalie. The objective of this research is to carry on a comparison between the military security devices deployed by Italy and Great Britain in East African Colonies during the period 1924-1939. This research focuses on the indigenous African troops – the askari/askari - recruited and employed by Italians in Eritrea and Somalia, and by the British in Somaliland, Kenya, Uganda, Tanganyika, Nyasaland and Sudan. At the present, this chronological and geographical context has been scarcely investigated from a comparative and trans-colonial perspective, not to mention the fact that some of these colonial corps have received little attention from both national historiographies, especially the Somali askari/askari.

碩士<br>國立臺灣大學<br>醫療機構管理研究所<br>92<br>The solo practice has been a major operation model for the majority of physicians’ clinics for a long time. Lately the operation of solo practice by physician has become difficult because of the prosperous development of hospital, tightness of national health insurance financing, expensiveness of medical apparatus, the increasing of consumers’ educational level, the changes of the consumers’ behaviors and habits, and etc. Group practice can improve comprehensiveness quality of physicians’ treatment and service, increase patients access and reduces medical costs. Moreover, group practice elevates the level of medical treatments and improves quality of physicians’ life. This study is aimed to explore the following issues： 1. To understand the physicians’ knowledge and attitude on the issue of group practices in Taipei County. 2. To understand the physicians’ choice on the group practice behavior. 3. To explore factors related to physicians’ knowledge, attitude and behavior in the issue of group practice. 4. To analyze the relationship among the physicians’ knowledge, attitude, and behavior in the issue of group practice. This is a survey research that discusses the physicians’ knowledge, attitude and behavior in group practices. The definition of group practices is the provision of health care services like consultation, diagnosis and treatment by a group of two or more licensed physicians engaged in a formally organized and legally recognized entity. It also can joint use of equipment and manpower. The research population of this study were 5003 physicians registered at Taipei County, 1008 among the 5003 physicians censored responded（20.15﹪response rate）. The goodness of fit tests between the subjects and population show that the subject represents the population well. Data was analyzed by four subsets including demographical characteristic, knowledge and attitude toward group practice, complaint, and practice behavior to serve the purposes. As to the understanding level of definition and advantage disadvantage of group practice, more then 90﹪of respondents expressed understanding, and more then 60﹪of respondents expressed willing to participating group practice. The physicians of Taipei County have high grade on knowledge of definition and advantage disadvantage, and related laws of group practice, except financial affairs. Physicians toward for attitude group practice, by factor analysis, three factors such as “prompting factor”, “personal feeling factor”, and “law factor were dentified”, and the physicians endorsed the attitude questions. On the practice behavior choice, most physicians hope for working with different doctors, sharing out the ownership and management, distributing income based on performance, and sharing cost through consensus building. Three suggestions were made according to research findings. First, the health authorities should communicate more about laws of group practice, and answer the physicians’ worries and anxieties by successful case. Second, the health authorities should legislate some laws to give providing experience physician incentives in participating group practice, and integrate all appellation into group practice. Finally, the study also suggests that future study discuss key successful factors.

碩士<br>高雄醫學大學<br>口腔衛生科學研究所碩士在職專班<br>91<br>The Research Analysis of Knowledge Attitude and Practice（K.A.P.）investigation of dentists toward Dental Global Budget System of National Health Insurance－Example in Southern Area. Kaohsiung Medical University Graduate Institute of Oral Health Science 8945022 Cheng Po Jen Direct Professor:Shun-Te Huang Abstract The dental clinic global budget system（GBS） has been carried out for more than 4 years. We wanted to understand the correlations between dentist，s personal specified character、sex and age groups、clinic practice experiences and knowledge、attitudes、agreement degrees of comparison GBS pre. and post. methods of improvement policies。 By way of questionnaires through postmail，we got 107 subjects from 987 mailed questionnaires，the dataset of our research was almost the same when compared with dentists all in Taiwan。 In our study，most of the subjects were 40-49 years old、male、graduated from KMU、practiced in Tainan、 dental clinic place located in cities（and county）more than the town or downtown suburb ,11-15 years practice experiences、main boss of the dental clinic、not the partner or other dentists。 Dental assistants were less than 2（included）、majored in general practice not specified in endodontic or periodontal part. or other specified part。 They practiced in clinic more than 50 hours per week、average dental patients were 11-20 per day、also average reward from NHIB was more than 400000、the reward from his（her）clinic other than NHIB was less than 25 percents when compared to NHIB。 The analysis from datasets showed dentists pay more attention to reward from NHIB、point number account from GBS、some special dental examination issues than other policies or carried out legal relative issues about GBS。Attitude、comparison between pre -GBS and post- GBS 、opinion toward improvement or reform policy，the satisfaction degrees were less than non-satisfaction，the agreement degrees were less than non-agreement degrees,too In conclusion we suggest（1）more GBS report conference on schedule for all dentists（2）leaders of Committee of dental global budget system should establish self-restraint or benefits-noninvolving articles to carry out some related policies fair（3）the personnel of Bureau of NHI should deal with administrative matters more tender and carefully（4）leaders from six branches of Committee of dental global budget system should select improved programs from basic local dentists， voice and readily accept their good advice。 We hope our related-improved systems could set into action more smooth and go long-term。 Keywords：Global budget system（GBS）， Satisfaction degree, Agreement degree ， Committee of dental global budget system（CDGBS）
