Purpose - The objective of this study is to investigate the differences and interaction effects on the perceived financial risk between Korean and Thai consumers according to the types of product(utilitarian and hedonic) and price discount (bundle and 50%off). Research design, Data and Methodology - This paper sets up 6 research subjects. Data collection was carried out in Korea and Thailand. Data was made of 154 Korean and 147 Thai consumers. As for the independent variables for this study, consumer types are composed of Korean and Thai consumers, price discount types were bundle(1+1) and 50% off price, and product types consist of utilitarian and hedonic product. The dependent variable is perceived as a financial risk. Each question is measured as a Likert-type five-point scale. Results - According to the price discount and product type, perceived financial risk of Thai consumers is confirmed to be a larger one than that of Korean consumers. Also, there are interaction effects in the perceived financial risk. Conclusion - Our findings can be used as useful information for global retail markets as marketing strategies in future Korean enterprise through a comparative study on Korean and Thai consumers.

Purpose - A product bundling is a marketing approach where multiple products or components are packaged together into one bundle solution. This paper aims to introduce an optimal bundle search problem (hereinafter called "OBSP") which may be embedded with online recommendation system to provide an optimized service considering pairwise discount and delivery cost. Research design, data, and methodology - Online retailers have their own discount policy and it is time consuming for online shoppers to find an optimal bundle. Unlike an online system recommending one item for each search, the OBSP considers multiple items for each search. We propose a mathematical formulation with numerical example for the OBSP and analyzed the complexity of the problem. Results - We provide two results from the complexity analysis. In general case, the OBSP belongs to strongly NP-Hard which means the difficulty of the problem while the special case of OBSP can be solved within polynomial time by transforming the OBSP into the minimum weighted perfect matching problem. Conclusions - In this paper, we propose the OBSP to provide a customized service considering bundling price and delivery cost. The results of research will be embedded with an online recommendation system to help customers for easy and smart online shopping.

A steam generator tube rupture accompanying a core damage may cause the fission product to be released to environment bypassing the containment. In such an accident, the steam generator is the major path of the radioactive aerosol release. AEOLUS facility, the scaled-down model of Korean type steam generator, was built to examine the aerosol removal in the steam generator during the steam generator tube rupture accident. Integral and separate effect tests were performed with the facility for the dry and flooded conditions, and the decontamination factors were presented for different tube configurations and submergences. The dry test results were compared with the existing test results and with the analyses to investigate the aerosol retention physics by the tube bundle, with respect to the particle size and the bundle geometry. In the flooded tests, the effect of submergence were shown and the retention in the jet injection region were presented with respect to the Stokes number. The test results are planned to be used to constitute the aerosol retention model, specifically applicable for the analysis of the steam generator tube rupture accident in Korean nuclear power plants to evaluate realistic fission product behavior.

Product image location in search engine advertising plays an important role in consumer perception when the product is relatively low involved and has functional value. The purpose of this research is to investigate the interaction effects of product image location and product type on advertising effectiveness. Building on the literature of location effects, we show that for products for which heaviness is considered a positive attribute, product image placed on the right are preferred. To test hypotheses, a 2(product image location: left vs. right) × 2(product type: single vs. bundle) experiment is conducted and a total of 144 paricipants took part in the experiment. The results revealed that respondents show higher brand attitude and purchse intention toward a bundle product's advertising with product image place on the right. The results provide implications and suggestions for improving search engine advertising and marketing strategies.

Purpose: This study investigates how to successfully promote the smart product bundle by exploring (1) how consumers' adoption intention toward a smart product bundle differs by the complementarity level of the bundled items and (2) how the ad appeal type influences the effect of complementarity level on adoption intention via goal fluency. Research design, data and methodology: This study was a 2 (complementarity level: low vs. high) × 2 (ad appeal type: attribute vs. benefit) between-subjects experiment. The proposed hypotheses were verified using analysis of variance (ANOVA) and bootstrap analysis using PROCESS. Results: This research demonstrated that adoption intention toward smart products increases when the complementarity level of bundled smart items is high. Goal fluency underlies this relationship. Further, attribute versus benefit appeal type moderates the relationship between the complementarity level and goal fluency. Conclusions: Compared with the attribute appeal, benefit appeal leads to higher goal fluency when the complementarity level of the bundled items is low. However, there was no differential impact of appeal type on goal fluency when the complementarity level of bundled items is high. Finally, goal fluency mediated the interaction of complementarity level × ad appeal type on adoption intention.

It is shown that for $A_{k, m}$ a k-homogeneous $C^*$-algebra over $S^{2n - 1} \times S^1$ such that no non-trivial matrix algebra can be factored out of $A_{k, m}$ and $A_{k, m} \otimes M_l(C)$ has a non-trivial bundle structure for any positive integer l, we construct an $A_{k, m^-} C(S^{2n - 1} \times S^1) \otimes M_k(C)$-equivalence bimodule to show that every k-homogeneous $C^*$-algebra over $S^{2n - 1} \times S^1)$. Moreover, we prove that the tensor product of the k-homogeneous $C^*$-algebra $A_{k, m}$ with a UHF-algebra of type $p^\infty$ has the tribial bundle structure if and only if the set of prime factors of k is a subset of the set of prime factors of pp.

As a continuation of computing the zeta function of a regular covering graph by Mizuno and Sato in [9], we derive in this paper computational formulae for the zeta functions of a graph bundle and of any (regular or irregular) covering of a graph. If the voltages to derive them lie in an abelian or dihedral group and its fibre is a regular graph, those formulae can be simplified. As a by-product, the zeta function of the cartesian product of a graph and a regular graph is obtained. The same work is also done for a discrete torus and for a discrete Klein bottle.

This paper shows that internet retailers adjust the total expenses of their customer's purchase by the nominal price of each product and the delivery fee of the purchase. This paper compares the total expenses of purchasing a bundle of goods in the internet market against the total expenses of purchasing the same bundle of goods in the traditional market. The results show that the type of goods and the total expenses of a purchase, together with their interaction, determine up to 60% or 80% of the variance of the difference between the expenses up the same purchase in the two markets. The results also show that neither the expenses of a purchase nor its interaction with the product type affects the dispersion of total purchase expenses in the internet market.

This study explore how framing affects the consumer's attitude toward the bundle products. On the basis of the framing theory, response compatibility hypothesis and regulatory focus theory, this study examine the impact of framing on the consumer's choice in multi-alternative set and analyzes the manner in which he/she selects or rejects an alternative. The data obtained from experiment shows that : 1. Consumers focus on the positive attributes of in selection task, however, in rejection task he/she will focus on negative attributes. 2. Consumers are not influenced by prevention framing when he/she selects an alternative however, he/she is not influenced by promotion framing when reject an alternative. Understanding the underlying cognitive process of choosing abd rejecting in multiple alernatives can help marketers to create effective framing strategies for the bundle product.
