  • We initiate the study of interval-valued fuzzy quasi-ideal of a semigroup. In Section 2, we list some basic definitions in the later sections. In Section 3, we investigate interval-valued fuzzy subsemigroups and in Section 4, we define interval-valued fuzzy quasi-ideals and establish some of their basic properties. In Section 5, we obtain characterizations of regular and intraregular semigroups using the machinery developed in the preceding sections.

  • The notion of regularity in near-ring was generalized by the concept of b-regular and some characterizations of the same was obtained through the substructures viz bi-ideals in near-rings. In this paper, we generalize further and introduce tile notion of weakly b-regular near-rings and obtain a characterization of tile same.

  • Houses contain our own characteristics and philosophy. As a Yangban house in the late Joseon Dynasty, the house of Kwon Hee-moon was constructed over 250 years to the present. Therefore, this house can more objectively examine the aesthetic ideals, such as the thoughts and philosophies of the house owners across the generations. The name of Sarang-Chae is Ui-Wang-Seo(嶷汪棲), it shows thoughts and philosophies symbolically. Ui(嶷)·Wang(汪) mean the elements of nature, and Seo(棲) symbolizes living together, It is aesthetics of Nature, aesthetics of Human boundary. Aesthetics of Nature boundary is aesthetics of Ui(嶷)·Wang (汪), so it is clear and fine. Aesthetics of Human boundary is aesthetics of Seo(棲), so it has meditation and purity. As such, the aesthetic ideal of Kwon Hee-moon's house pursues the ideal of life. Through the aesthetic boundary of the house of Kwon Hee-moon, we can understand the aesthetic boundary of Honam Yang-ban House in the Late Chosun Dynasty.
