In deze paper werd er onderzoek gedaan naar de ratingmodellen van de drie grote ratingbureaus S&P, Moody's en Fitch. In de huidige economische conjunctuur met veel downgrades in de afgelopen jaren, is het belangrijk na te gaan of deze ratingbureaus wel correct en consistent zijn in het raten van landen. We hebben als hypothese gesteld dat ratingbureaus niet altijd een rechtvaardige rating aan landen toekennen op basis van ons model. Om de ratingmodellen van de drie ratingbureaus te bepalen, hebben we ons gebaseerd op de belangrijkste variabelen om een rating te bepalen. Deze variabelen zijn BBP per capita - wat later werd opgenomen als BBP groei -, inflatie, politieke stabiliteit, buitenlandse schuld / BBP en de vertraagde van de rating. Het schatten gebeurt via een ordered probit model.

This thesis focuses on porous monolithic materials that are not in the forms of particles, fibers, or films. In particular, the synthetic strategy of porous monolithic materials via the sol-gel method accompanied by phase separation, which is characterized as the non-templating method for tailoring well-defined macropores, is described from the basics to actual synthesis. Porous materials are attracting more and more attention in various fields such as electronics, energy storage, catalysis, sensing, adsorbents, biomedical science, and separation science. To date, many efforts have been made to synthesize porous materials in various chemical compositions-organics, inorganics including metals, glasses and ceramics, and organic-inorganic hybrids. Also demonstrated in this thesis are the potential applications of synthesized porous monolithic materials to separation media as well as to electrodes for electric double-layer capacitors (EDLCs) and Li-ion batteries (LIBs). This work is ideal for graduate students in materials science and is also useful to engineers or scientists seeking basic knowledge of porous monolithic materials.
