Purpose: This study focuses on the buying Korean products by Chinese consumers through overseas direct purchase as a distribution means (tool) because they are interested in Korean products because of their excellence. Major variables are national brand, curiosity, price, product quality. Research design, data, and methodology: To make effective analysis, several tools and programs for analysis are used with SPSS Statistics ver. 23.0 and AMOS 23.0. Results: National brand, price, product quality have affirmative impacts on satisfaction and repurchase through overseas direct purchase. But curiosity does not have. Among them the most important variable is product quality. This is the same as Chinese consumers think product quality is the most valuable one when buying Korean products through overseas direct purchase. Next one is price. The last one is a national brand. Conclusions: Among the variables of overseas direct purchase, product quality has the biggest impact on satisfaction and repurchase positively. This means that many Chinese consumers are interested in product quality manufactured in Korea. Also Korean product quality is better than that of China until now. Korean companies should, strongly and continuously, have to improve the quality of Korean products because China focuses on product quality in the distribution process in the national base.

The study examined the moderating effects of the relationship among purchase motivation, satisfaction, and loyalty in a farmer-to-consumer direct market. Data were collected from 426 consumers of direct sale agricultural products who visited nine rural villages across the country. The SPSS 15.0 and LISREL 8.80 statistical package were used for frequency, reliability, exploratory factor, confirmatory factor, and path analysis. Results showed that 'product factor', 'experience factor' and 'economic factor' among purchase motivation had positive effects on satisfaction and satisfaction had positive effects on loyalty. The analysis also indicated that gender moderated the relationship among purchase motivation, satisfaction, and loyalty. Whereas product and economic factors among purchase motivations had positive effects on satisfaction in the male group, product and experience motivation were important factors for female group. These results could enable direct sales marketers to develop marketing techniques to expand farm sales.

A digraph D is primitive if there is a positive integer $k$ such that there is a walk of length $k$ between arbitrary two vertices of D. The exponent of a primitive digraph is the least such $k$. Wielandt graph $W_n$ of order $n$ is known as the digraph whose exponent is $n^2-2n+2$, which is the maximum of all the exponents of the primitive digraphs of order n. It is known that the diameter of the multiple direct product of a digraph $W_n$ strictly increases according to the multiplicity of the product. And it stops when it attains to the exponent of $W_n$. In this paper, we find the diameter of the direct product of Wielandt graphs.

Purpose - This study was carried out to analyze the influential factors of how consumers methodize purchasing agricultural products via direct market. It further utilizes the Discrete Choice Model to analyze consumer decision specifically with regards to individual markets and store attributes. Research design and methodology - This study will use the multinomial logit model to interpret the influential factors behind selecting a specific market to purchase from. This study establishes 'online direct-purchase' as the base category with 'direct farm markets', 'local foods direct markets', 'produce boxes (CSA)' as substitutes. Results - Firstly, the variety of products, price and freshness had a positive influence on choosing 'direct farm markets' while convenience of payment and transportation had a negative influence. Second, freshness and store attributes had a positive influence on choosing 'local foods direct markets' but product price and packaging, location accessibility had a negative influence. And although product creditability had a positive influence on purchasing 'produce boxes (CSA)', product price had a negative influence. Conclusions - Accordingly, there is a need for the South Korean government to encourage the adoption of mobile payment through smartphone applications in direct farm markets to vitalize direct agricultural purchasing. However, this does need to be approached cautiously as price has a conflicting affect for each method of purchase.

The paper introduces the concept of direct product and discusses some basic facts about distant ideals. We also introduce the definition of directly indecomposable in an autometrized algebra. Furthermore, we present the concept of a subdirect product and simple autometrized algebra and its behavior. We also introduce the definition of subdirectly irreducible in an autometrized algebras. In particular, we prove that every subdirectly irreducible monoid autometrized algebra is directly indecomposable. Finally, we discuss different properties of chain autometrized algebras and introduce the representability in the autometrized algebra. We also prove that if a weak chain monoid normal autometrized l-algebra is nilradical, then it is representable.

This paper presents a systematic study for theoretical aspects of a unified approach to the abstract relative Fourier transforms over canonical homogeneous spaces of semi-direct product groups with Abelian normal factor. Let H be a locally compact group, K be a locally compact Abelian (LCA) group, and ${\theta}:H{\rightarrow}Aut(K)$ be a continuous homomorphism. Let $G_{\theta}=H{\ltimes}_{\theta}K$ be the semi-direct product of H and K with respect to ${\theta}$ and $G_{\theta}/H$ be the canonical homogeneous space (left coset space) of $G_{\theta}$. We introduce the notions of relative dual homogeneous space and also abstract relative Fourier transform over $G_{\theta}/H$. Then we study theoretical properties of this approach.

In a number of earlier papers the study of the structure of semigroups has been approached by means of right congruences. Such n approach seems appropriate since a right congruence is one of the possible analogs of both the right ideal of a ring and the subgroup in a group. Each of these substructures plays a strong role in the study of the structure of their respective systems. in both the ring and the group the internal direct product is nat-urally and effectively defined. however what such an internal direct product should be for two right congruences of a semigroup is not so clear. In this paper we will offer a possible definition and consider some of the consequences of it. We will also extend some of these results to automata.
