A lab-scale apparatus for turbid water transport control was tested and examined. The channel had a dimension of $100cm{\times}30cm{\times}15cm$ (length${\times}$hight${\times}$width). And the turbidity water was prepared using two types of particles, bentonite and loess. The channel equipped with filamentous mat was operated under various shock load conditions. In the control channel, instantly, turbid water mixed with the clean water inside the channel and turbidity prevails the entire channel. While in the mat-equipped channel, it increases only at the bottom. Overall, the filamentous mat gave capture efficiency of 70~90% compared with the control group. The capture efficiency of turbid particles decreased with increased input turbidity flux. The result of experimental run on how turbid particles are separated in the mat channel shows that settling, filtration and attachment are the main processes. Meanwhile, turbidity was diffused from the channel bottom due to turbidity gradient before and after mat zone. The particle size before mat zone was lightly coarser than that after mat zone.

Cats used to be long avoided in Korean culture due to prejudices on their negative implications, yet they are increasingly being favoured by domestic readers along with a growing number of cat lovers, picture books, essays and webtoons. In the case of Yoko Sano's work, half of her published books in Korea depicts cats. Among those is 'The Cat That Lived a Million Times' which is a worldwide million seller. The research analyses five picture books on cats published in Korea, focusing on finding out symbolic representation of cats other than merely being the protagonist of the book. Sano asserts that we respect our own free well and love ourselves just as cats do in her books. In conclusion, cats in Sano's work mostly represent the author herself, which are sometimes depicted as mother and son. The colours and thick outlines of her cats, unlike tender characteristics, describes self-righteous strong personality, while emphasising both static and dynamic movements.
