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.

본 연구는 관여도가 상대적으로 낮은 기능적 가치를 추구하는 제품의 검색광고를 평가할 때, 제품 이미지의 위치와 판매단위유형 간의 일치성에 따라 광고효과가 달라질 수 있다고 보았다. 이에 본 연구의 목적은 제품검색광고에 나타나는 제품 이미지의 위치(왼쪽 vs. 오른쪽)와 판매단위(낱개 vs. 묶음)가 광고태도, 브랜드태도, 그리고 구매의향에 미치는 영향을 탐색하는데 있다. 연구가설을 검증하기 위해 144명의 참가자를 대상으로 2×2 요인설계로 실험을 진행하였는데 독립 변인으로서 제품검색광고 내 제품 이미지의 위치, 제품 판매단위 두 가지 변인을 설정하였고, 종속변인으로 광고태도, 브랜드 태도, 구매의향을 측정하였다. 본 연구 결과는 제품 이미지의 위치와 판매단위의 상호작용 효과가 브랜드 태도, 구매의향에 미치는 것으로 나타났는데 묶음 단위의 제품 광고에서 오른쪽에 제품 이미지가 위치할 때 브랜드 태도와 구매의향이 높아졌다. 본 논문의 결과를 기반으로 학문적 시사점과 향후 쇼핑 플랫폼, 온라인 스토어 등에 관심있는 실무자에게 유용한 시사점을 제공하여 후속연구에 대한 방향성을 제시하고 있다.

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.

본 연구는 소비자들이 묶음제품의 가치를 평가하는 메카니즘을 이해하여 향후 보다 성공적인 묶음제품 전략 방안을 제시하는 데 그 목적이 있다. 반응 조화설 및 프레이밍 이론, 조절 초점이론에 근거하여 같은 묶음 제품이라도 번들 구성 요소나 혜택을 어떤 방식으로 제시하느냐에 따라 고객의 태도에 영향을 미칠 것이라 보았으며, 특히 마음에 드는 옵션을 선택하는 상황과 마음에 들지 않는 옵션들을 제거해 나가는 각기 다른 상황에 따라 각각 그와 적합성이 맞는 프레이밍 방법을 사용하면 고객의 긍정적인 반응을 유도할 수 있을 것이라는 연구 가설을 검증하기 위하여 실험을 실시하였다. 이를 통해 묶음 제품 옵션의 선택/제거 상황에 따라 향상적 프레이밍 혹은 방어적 프레이밍이 각각 다른 효과를 미친다는 점을 발견할 수 있었다.
