Entre conservation et intégration : les aires protégées en Asie du sud-est continentale, 1962-2005 : une étude des parcs Cát Tiên au Viêt Nam, Si Lanna et Doi Suthep-Pui en Thaïlande

Vanhooren, Romain 06 1900 (has links) (PDF)
Depuis les années 1960, la couverture forestière de l’Asie du Sud-Est continentale a été réduite de plus du tiers. C’est également au début des années 1960 qu’une conscience environnementale s’est développée dans la région et plus particulièrement au Vietnam et en Thaïlande. Cette conscience environnementale associée à des intérêts commerciaux, à des questions politiques de « sécurité nationale » ainsi qu’à une croissance élevée de la population, a abouti, quelques années plus tard, à un développement considérable des réseaux d’aires protégées dans les différents pays de la région. Mis en place progressivement et principalement dans les régions montagneuses, ces parcs et réserves ont contribué, de façon plus au moins volontaire, à « coloniser » des espaces périphériques et donc à mieux les intégrer aux ensembles nationaux qui ne contrôlaient parfois pas du tout ces territoires il y a cinquante ans. En effet, à l’intérieur de la majorité des États, en particulier ceux d’Asie du Sud-Est continentale, des territoires sont éloignés des lieux où se prennent les décisions politiques et économiques; peuplés faiblement ou par des groupes ethniques différents, difficiles d’accès, ils apparaissent finalement comme des territoires périphériques et l’on peut dire qu’ils sont marginaux. L’hypothèse retenue dans le cadre de cette recherche est que la délimitation de territoires voués à la protection et à la conservation des forêts constitue, en Asie du Sud-Est, une réponse parmi d'autres face aux problèmes environnementaux mais également un outil d’intégration territoriale notamment des régions marginales. / Since the 1960’s, the forest cover of continental Southeast Asia was reduced by more than a third. From that time on, an environmental consciousness developed in the region, particularly in Vietnam and in Thailand. This environmental consciousness, in a context where trade interests, national security and population growth were all contributing to a specific socio-economic framework led, a few years later, to the development of a protected area system in all the countries. Set up gradually and mainly in the mountainous areas, these parks and reserves contributed to better integrate peripheral territories into national bodies; some of these territories were hardly controlled fifty years ago. Indeed, within the majority of the States, in particular those of continental Southeast Asia, some territories are far from the places where are taken the political and economic decisions; slightly populated or by different ethnic groups, difficult of access, they seem peripheral territories finally and one can say that they are marginal. The assumption behind this research is that, in Southeast Asia, the delineation of territories dedicated to forest protection and conservation constitutes, on the one hand, a response among others to solve what is considered an environmental problem but also, on the other hand, a tool for territorial integration, which is particularly efficient in marginal areas.

High-frequency transformer model for switching transient studies

Chimklai, Suthep 05 1900 (has links)
The objective of this thesis is to develop a simplified high-frequency model for three-phase, two- and three-winding transformers. The model is an extension of the classical 60 Hz model which includes two important factors prevailing in transformers under transient conditions: stray capacitances which cause transformers to resonate and frequency dependent characteristics of the leakage flux and winding resistances due to skin effects. The model is not aimed to represent internal details of the transformer and only lumped circuit parameters are used in order to simulate terminal behaviours of the transformer. However, it is different from other terminal models in that it is not just an impedance or admittance black box derived from measured transfer functions. Only the meaningful parameters which correspond to the physical components in the real transformer are included in the model. The short-circuit impedances T-form of the classical model is retained which makes it possible to separate the frequency-dependent series branch form the constantvalued capacitances. In addition, it enables the model to be built at the coil level which is independent of winding connections. The model stray capacitances are placed at the corresponding coils terminals. If they link two coils they will be split into two halves with one half connected at the upper ends and the other half at the lower ends. The frequency dependent series branch is divided into sections corresponding to various sections in the transformer coil which can be assumed uniform. An RL equivalent network is used to synthesise the frequency dependent behaviour of each section. The values of R's and L's are calculated from minimum-phase-shift approximations which guarantees numerical stability of the resulting network. With the use of symmetrical components, mathematical complications of fitting mutual impedance functions are avoided and also the number of impedance functions to be fitted by rational functions is reduced. A number of short-circuit tests on the actual power transformers installed in the Thailand 's power system were performed to determine the parameters of the model. The frequency responses calculated from the model are compared with the tests. Also, a timedomain test was conducted and the result was used for comparison with the simulation from the model.

Job Satisfaction Among Faculty Members at Non-Metropolitan Teachers Colleges in Central Thailand

Karoonlanjakorn, Suthep 05 1900 (has links)
The Faculty Job Satisfaction/Dissatisfaction Scale developed by Olin R. Wood (1973) was employed in this study to determine what significant differences and level of faculty job satisfaction existed on each facet of job satisfaction and in overall job satisfaction among faculty members at non-metropolitan teachers colleges in central Thailand. The results of this study were compared with the findings of Vatthaisong (1982) in a similar study of faculty members at teachers colleges in northeast Thailand. The instrument consists of two parts: the first part includes seven demographic items, and the second part has 68 items and uses a six-point rating scale for ten facets of job satisfaction, including one-single item of overall satisfaction. A sample of 288 faculty members at non-metropolitan teachers colleges in central Thailand was randomly selected. A total of 253 faculty members or 87.85 percent of the sample participated in this study. Frequencies, percentages, means, one-way ANOVA, and two-way ANOVA were used for analyses. The level of significance was set at .05. The Scheffe method for post hoc comparison was adopted following one-way ANOVA.
