Using a nationally representative survey fielded in 2009, we analyze the relationships between personality traits and various modes of political participation in South Korea. We find statistically significant relationships between personality (measured by the Five‐Factor Model) and several nonelectoral modes of participation. Openness correlates positively with protest participation, rally attendance, financial contributions to political causes, news media contacts, and political activities via the Internet. Agreeableness correlates negatively with these five participation modes as well as petition signing. Conscientiousness is positively associated with individual political acts (e.g., contacting news media and elected officials and donation), while it is negatively associated with collective actions such as participation in rally. However, we do not find any significant relationship between personality and voter turnout. Reflecting an unusually conflictual political climate of South Korea in 2008, we discuss these findings' implications focusing on the personality‐situation interactions.

separation tasks occurs frequently in bio-product purification processes. The use of one more SMB unit, however, results in much higher operation and maintenance costs, compared to the use of a single SMB unit. It is obvious that the application of a single SMB unit is more advantageous if it can meet the product specification such as product purities.Recently, there have been several studies on the use of a single SMB unit for ternary separation or centre-cut separation. Among them, major attention has been paid to a single SMB unit with five zones (hereafter "five-zone SMB") (Beste and Arlt, 2002;Kim et al., 2003;Wang and Ching, 2005) and a single SMB unit with two zones (hereafter "two-zone SMB") Wankat, 2005, 2006;. The structure of a five-zone SMB is briefly explained below while the details of a two-zone SMB A ternary separation usually requires the use of two simulated moving bed (SMB) units in series. Since an increase in the number of SMB units leads to a significant increase in capital and operational costs, the use of a single SMB unit is preferred if its structure can be modified to treat a ternary separation. Such a modified single SMB unit has been typified by a five-zone SMB or a two-zone SMB so far. The separation performances of a five-zone SMB and a two-zone SMB are compared in this paper by using the ternary amino acid mixture as a model system. A five-zone SMB is designed with the safety margin method while a two-zone SMB is optimized using genetic algorithm. A five-zone SMB based on the maximum allowable safety margin, although it may not guarantee the global optimum solution, results in much better separation performance than a two-zone SMB at its global optimum state.Une séparation ternaire fait habituellement appel à deux unités de lits mobiles simulés (SMB) en série. Étant donné qu'une augmentation du nombre d'unités SMB entraîne une hausse significative des coûts en capital et de fonctionnement, l'utilisation d'une seule unité SMB est préférable si sa structure peut être modifiée pour traiter une séparation ternaire. Ce type d'unité SMB unique modifiée prenait jusqu'ici la forme d'un SMB à cinq zones et d'un SMB à deux zones. Dans cet article, on compare les performances de séparation d'un SMB à cinq zones et d'un SMB à deux zones en utilisant un mélange ternaire d'acides aminés comme système modèle. Un SMB à cinq zones a été conçu à l'aide d'une méthode avec marges de sécurité tandis que le SMB à deux zones a été optimisé à l'aide d'un algorithme génétique. Le SMB à cinq zones basé sur une marge de sécurité possible maximale, bien qu'elle ne garantisse pas forcément la solution optimale globale, présente une performance de séparation nettement meilleure que le SMB à deux zones à son meilleur état optimal.
