The purpose of this study was to investigate the effects of elderly generation sympathy, family intimacy and age-friendly environment of young and middle-aged generations on supporting the older adults, and to identify differences of influencing factors among generations. With these purpose, we used data of the '2017 Age Integration Survey' provided by the Humanities and Social Capacity Enhancement Project in Korea Research Foundation. The analysis of the data was performed on 640 participants who were between 18 and 64 years old, and they were selected from total 1017 study population. The analysis method was the Structural Equation Model(SEM). The results of this study were as follow. Firstly, elderly generation sympathy and family intimacy were significant statistically significant effect on the notion of supporting the older adults positively to all generations. Secondly, the relationship between the notion of supporting the older adults and the influential factors suggested in this study was found to be significant among the generations. Thirdly, the young generation showed a statistically significant effect on the notion of supporting the older elderly generation sympathy and family intimacy. Elderly generation sympathy and family intimacy had a significant statistical impact in the middle aged generation, however, age-friendly environment significant statistically significant effect on notion of supporting the older adults negatively. With these results, we presented practical and policy suggestions to enhance the notion of supporting the older adults.

We introduce the notion of Gauss map of pointwise 1-type on ruled surfaces in the Euclidean 3-space for which vector valued functions is neither trivial nor it extends or coincides with the usual notion of 1-type, in general. We characterize the minimal helicoid in terms of it and give a complete classification of the ruled surfaces with pointwise 1-type Gauss map.

In this short note, we find bases of the centers of generic Hecke algebras associated with certain finite Coxeter groups. Our bases are described using the notion of cell datum of Graham and Lehrer, and the notion of norm.

The notion of rough sets was introduced by Z. Pawlak in the year 1982. The notion of a $\Gamma$-semigroup was introduced by M. K. Sen in the year 1981. In 2003, Y. B. Jun studied the roughness of sub$\Gamma$-semigroups, ideals and bi-ideals in i-semigroups. In this paper, we study rough prime ideals and rough fuzzy prime ideals in $\Gamma$-semigroups.

We show that any filter of Tarski algebra can be de-composed into the union of some sets. Moreover, we introduce the notion of expansions of filters in Tarski algebras, and discuss the notion of ${\sigma}$-primary filters in Tarski algebras. Finally, we show that there is no non-trivial quadratic Tarski algebras on a field X with $|X|{\geq}3$.

In this paper, we introduce the notions of pregroups, post-groups and pre-B-algebras, and we investigate their relations. Using this notions we give another proof that the notion of B-algebras coincides with the notion of pregroups.

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.

The notion of finite type submanifold was introduced by B.-Y. Chen [1]. A lot of works were done in this field of study by many authors. B.-Y. Chen also extended this notion to pseudo-Riemannian submanifold of pseudo-Euclidean space ([2]).

Using the Bu$\c{s}$neag's model ([1, 2, 3]), the notion of pseudo-valuations (valuations) on a ${\mathbf{BCK/BCI}}$-algebra is introduced, and a pseudo-metric is induced by a pseudo-valuation on ${\mathbf{BCK/BCI}}$-algebras. Based on the notion of (pseudo) valuation, we show that the binary operation in ${\mathbf{BCK/BCI}}$-algebras is uniformly continuous.

In this paper, we give and study the notion of computer topological function space between computer topological spaces with $k_i$ adjacency, i $\in$ {0, 1}. Using this notion, we study various properties of topologies of a computer topological function space.
