  • Three kinds of cationic acrylamide copolymer with different branch degree were prepared controlling the dosage of N, N'-methylenebisacrylamide. The physical characteristics of the branch-degree-modified copolymers were analyzed by intrinsic viscosity and charge density. The branch degree measurements were investigated by applying the colloidal titration phenomena using a spectrophotometer and comparison with the cationic regain measurement method. The results showed that the absorbance behaviors of spectrophotometer were distinctively different with the branch degree of copolymers. Also, the branch degree determinations and molecular structure estimations of the copolymers were numerically measured by applying the titration phenomena using a spectrophotometer. Finally, three kinds of branch-degree-modified copolymers were applied to flocculation test using arbocel micro pulp for the determination of flocculation behavior by different morphology of cationic acrylamide copolymers.

  • The CDP in Korea has been enforced for conserving resources and reducing environmental pollution since March, 1999. Therefore this thesis aims to investigate the degrees of consumer participation(CP), recognition and support, and to analysis of demographic variables, consumers' psychology, and attitudes which may influence the degrees of CP recognition, and support for the CDP. The results were as follows: First, the time of surrey was found to be statistically significant in consumer recognition and support. The degree of recognition was the lowest in first time. And the degree of consumer support was the highest in first time. Second, education, employment status and house shape were found to be statistically significant. The degree of consumer recognition was the highest among junior college graduates. The employed group was found to be the highest in the degree of participation. Third, the significant factors which influenced the degree of recognition was the time of survey, the perceived difficulty, effectiveness of the Consumer Deposit Program. The perceived difficulty, the time of survey were found to be related with the degree of consumer support. The most influential variables which influenced the degree of consumer participation were house shape, the perceived effectiveness, the degree of resource recycling, job and the degree of consumer recognition.

  • The interpretations of degree expressions require the postulation of new entities to represent degrees. Diverse entities such as degrees, intervals, and vectors are adopted for degree expressions. Positive degree sentences and questions are properly construed with the introduction of these entities, but their negative counterparts need more consideration. Negative degree sentences show dual patterns of entailments depending on contexts, and negative degree questions are unacceptable, making weak islands. To explicate the distinct nature of negative degree sentences and questions, Fox & Hackl (2006) provide an analysis based on degrees while Abrusan & Spector (2010) suggest a proposal in interval readings of degree expressions. I have pointed out the theoretical problems of these analyses and proposed an alternative in the framework of the vector space semantics, following Winter (2005). Bi-directional scales in vector space fit well with the dual patterns of negative degree sentences, and the notion of a reference vector is useful to accommodate the contextual influence in negative degree sentences and to deal with the unacceptability of negative degree questions.
