Most companies are achieving economic benefits by producing products in the form of bi-national products, but there are also negative consequences such as reduced brand power, so strategic bi-national product planning and branding is essential. In order to actively reflect these practical needs, this study conducted a comprehensive and easy-to-generalize evaluation of Bi-national products that has been somewhat underdeveloped in previous studies. To this end, the selection and evaluation criteria of the products to be investigated were differentiated. This is to classify the products by place of use and the purpose of use so that the majority of bi-national products can be included, and then use the combination to derive the specific products to be evaluated for bi-national products. The evaluation of the product identified the phenomenon of psychological conflict among consumers due to the country of origin discrepancy at the level of decreasing brand authenticity. The above research design is an evaluation method that can encompass bi-national products as a whole, rather than an evaluation of a specific product or product line that is mainly reported in previous studies, and it is also very easy to apply to practice because it allows us to more carefully identify changes in psychological attitudes.

Intrinsic product of intuitionistic fuzzy sets are considered. Using this, characterizations of intuitionistic fuzzy subrings/ideals are discussed. The notions of intuitionistic fuzzy quasi ideals and intuitionistic fuzzy bi-ideals are introduced. Characterizations of regular rings are provided.

Recently Hui et al. ([8,9]) studied contact CR-warped product submanifolds and also warped product pseudo-slant submanifolds of a $(LCS)_n$-manifold $\bar{M}$. The characterization for both these classes of warped product submanifolds have been studied here. It is also shown that there do not exists any proper warped product bi-slant submanifold of a $(LCS)_n$-manifold. Although the existence of a bi-slant submanifold of $(LCS)_n$-manifold is ensured by an example.

This study aims to explain the cause of price differences of bi-national products based on consumer response of product type, distribution channel, and consumer nationality, respectively. Specifically this study investigated whether price discount and distribution channel affect consumer evaluation by luxury and non-luxury product type. In the case of bi-national product toward the non-luxury, price discount had positive influence on preference, regardless of distribution channel. By revealing the influence of price discount on bi-national products on consumer response of product type and distribution channel respectively, the study suggests meaningful implications for the strategic management of bi-national products.

A number of studies have been conducted on the evaluation of bi-national products, but studies that may be applied in practice are lacking. This study suggests several implications for bi-national products in the sub-market using a more specific approach than previous studies. To this end, this comprehensive comparative study reflects the purchasing routes, product category, and consumers' personal characteristics (regulatory focus, prior knowledge) of bi-national products. Results found the evaluation of bi-national products according to purchase routes showed that consumers in offline stores were more favorable than consumers in online stores. In comparison with product categories, necessities were more positive than luxury goods. On the other hand, according to consumer's personal characteristics, consumers with promotion focus tendency perceived brand preference more highly than consumers with preference focus tendency. Also, it was found that groups with high prior knowledge had a positive evaluation of products compared to low knowledge groups.

In this study, behaviors of removing Sb and Pb by oxidation of molten Bi-Pb-Sb alloy which is a by-product of non-ferrous smelting process was investigated. The molten alloy was oxidized at 1173 K by bubbling $N_2+O_2$ gas through a submerged nozzle. The Sb was removed and recovered as mixed phase of $Sb_2O_3$ and metal Sb. In the case of bubbling $N_2+O_2$ gas into molten Bi-Pb alloy at 923 K, Pb was oxidized and removed to slag. But Bi could not be refined due to simultaneous oxidization of Bi with Pb.

In this paper, we study doubly warped product point-wise bi-slant submanfolds of S-space form. Here we try to establish an inequality containing the Ricci curvature, squared norm of mean curvature and the warping function.

In this article, we derived Chen's inequality for warped product bi-slant submanifolds in generalized complex space forms using semisymmetric metric connections and discuss the equality case of the inequality. Further, we discuss non-existence of such minimal immersion. We also provide various applications of the obtained inequalities.

Characterizations of hesitant fuzzy left (right) ideals are considered. The notion of hesitant fuzzy (generalized) bi-ideals is introduced, and related properties are investigated. Relations between hesitant fuzzy generalized bi-ideals and hesitant fuzzy semigroups are discussed, and characterizations of (hesitant fuzzy) generalized bi-ideals and hesitant fuzzy bi-ideals are considered. Given a hesitant fuzzy set $\mathcal{H}$ on a semigroup S, hesitant fuzzy (generalized) bi-ideals generated by $\mathcal{H}$ are established.
