Diese Dissertation befasst sich mit einer vergleichende Analyse der beiden europaweit wichtigsten chinesischen Gemeinschaften und repräsentativsten Chinatowns in Paris und London hinsichtlich ihrer historischen, wirtschaftlichen, soziologischen und medienwissenschaftlichen Aspekte. Unter Berücksichtigung der verschiedenen Migrations- und Integrationspolitik der Ankunftsländer bezieht sich diese komparative Analyse, genauer gesagt, auf die chinesische Migrationsgeschichte um ihre sozio-ökonomische Lebenssituation vor Ort, Eingliederung in den Arbeitsmarkt, soziale Beziehung und Netzwerke, Ortsbindung und Heimatsgefühle sowie Erfahrung vom politischen Engagement. Die Ergebnisse der Analysen zeigen weiterhin drei Modelle der Chinatowns als Musterbeispiele Europas, erstens: die Chinatown vornehmlich mit wirtschaftlicher Konzentration, zweitens: die komplexe Chinatown mit gemeinschaftlicher, kultureller, wirtschaftlicher und sozialer Funktion und drittens: die Chinatown nach amerikanischem Stil als Konsum- und Vergnügungsort sowie Touristenattraktion.

Thesis (M.M.)--National Institute of Development Administration, 2016 ; This research was conducted qualitatively through review, analysis, and comparison of Chinese and Japanese policies regarding elderly policy. The methodology used in this study was literature analysis. Data on elderly population were collected from World Bank website and elderly policy documents were from a government website. The study aimed to (1) find out about the aging problem in China, (2) compare the policies on the elderly in China and Japan, and (3) provide policy recommendations for the Chinese government. The results showed that China has three main aging problems: (1) an increasing of demand for medical treatment, (2) the empty-nest family problem, and (3) increasing pressure on long-term nursing services. Many elderly policies have long been implemented but are not efficient. Japan was selected to do a comparison because Japan is a super-aged country and it has good experience to cope with aging problems. Through combining the situation of China, the Chinese government should create the way which pay attention to the improvement of policies for the elderly and implement target measures for all levels of aging. ; [preview](https://repository.nida.ac.th/bitstream/662723737/3757/5/b199679e.pdf.jpg)

In complex environments, path planning is the key for unmanned aerial vehicles (UAVs) to perform military missions autonomously. This paper proposes a novel algorithm called flight cost-based Rapidly-exploring Random Tree star (FC-RRT*) extending the standard Rapidly-exploring Random Tree star (RRT*) to deal with the safety requirements and flight constraints of UAVs in a complex 3D environment. First, a flight cost function that includes threat strength and path length was designed to comprehensively evaluate the connection between two path nodes. Second, in order to solve the UAV path planning problem from the front-end, the flight cost function and flight constraints were used to inspire the expansion of new nodes. Third, the designed cost function was used to guide the update of the parent node to allow the algorithm to consider both the threat and the length of the path when generating the path. The simulation and comparison results show that FC-RRT* effectively overcomes the shortcomings of standard RRT*. FC-RRT* is able to plan an optimal path that significantly improves path safety as well as maintains has the shortest distance while satisfying flight constraints in the complex environment. This paper has application value in UAV 3D global path planning.
