The purpose of this paper is to analyze supplier's optimal decision of the buyback price facing irrational retailers. It has been known that retailers show irrational ordering behaviors, such as pull-to-center effect. We model the retailer's pull-to-center behavior and derive the supplier's optimal buyback price considering the retailer's bounded rationality. The result shows that the supplier's profit can be significantly improved exploiting the retailer's irrationality in the ordering behavior.

Recently, firms have been putting forth significant efforts to fulfill various demands and high expectations of customers. The role and importance of customer centers as a direct contact point for customer relationship management are more emphasized than previously. A customer center draws attention as a new alternative to secure corporate competitiveness as it contributes to sales increase, being in a position to satisfy customers' needs by ensuring customers' access to information. A customer center is an aggregation of various information and communication technologies. In particular, a voice recognition/analysis technology based on big data can elaborate customer services further, enhance customer satisfaction, and trigger constant interactions with customers. A customer center can be transformed to a hub of customer knowledge and the embodiment of business intelligence in the front line of business. This article is a case study on how the customer center of the K life insurance company regarding customer center operation collects and analyzes customer information and how it has established its voice recognition/analysis system based on big data to improve customer experience management. Factors affecting the successful introduction and implementation of voice recognition/analysis system to a firm, are examined.

A responsibility center is important for businesses in controlling their business activities. A responsibility center accounting includes a structured system for dividing responsibilities to help assess activities to improve economic efficiency for businesses. The article is based on exploratory factor analysis using the ordinary least squares to test the model of the factors affecting the application of responsibility center accounting in Vietnamese enterprises. The article uses data including 482 samples of 200 Vietnamese enterprises such as CFOs, chief accountants, and accountants. The sample was selected randomly to ensure objectivity in the period 2020-2021. The research results show that there are three factors that have a positive impact on the application of responsibility center accounting of Vietnamese enterprises, including the qualifications and capabilities of managers, decentralization in management, and evaluation tools of the responsibility center accounting. In order to contribute to improving efficiency in the application of the responsibility center accounting for Vietnamese enterprises, leaders of Vietnamese enterprises need to raise awareness and professional qualifications, pay attention to the management level in a transparent and appropriate way to delineate and diversify the tools used to facilitate and achieve business performance.

Addition of probiotics to yogurt with desired health benefits is gaining increasing attention. To further understand the effect of probiotic Lactobacillus plantarum on the quality and function of fermented milk, probiotic fermented milk (PFM) made with probiotic L. plantarum K25 and yogurt starter (L. delbrueckii ssp. bulgaricus and Streptococcus thermophilus) was compared with the control fermented milk (FM) made with only the yogurt starter. The probiotic strain was shown to survive well with a viable count of 7.1 ± 0.1 log CFU/g in the PFM sample after 21 days of storage at 4℃. The strain was shown to promote formation of volatiles such as acetoin and 2,3-butanediol with milk fragrance, and it did not cause post-acidification during refrigerated storage. Metabolomics analysis by GC-MS datasets coupled with multivariate statistical analysis showed that addition of L. plantarum K25 increased formation of over 20 metabolites detected in fermented milk, among which γ-aminobutyric acid was the most prominent. Together with several other metabolites with relatively high levels in fermented milk such as glyceric acid, malic acid, succinic acid, glycine, alanine, ribose, and 1,3-dihydroxyacetone, they might play important roles in the probiotic function of L. plantarum K25. Further assay of the bioactivity of the PFM sample showed significant (p < 0.05) increase of ACE inhibitory activity from 22.3% at day 1 to 49.3% at day 21 of the refrigerated storage. Therefore, probiotic L. plantarum K25 could be explored for potential application in functional dairy products.

Using micro-Raman spectrometer, we investigated the evaluation of microstress on silicon surface after the local thermal oxidation. The induced stress of silicon surface after local thermal oxidation shows maximum value at the interface of silicon oxide and active area. The smaller the size of active area, the larger stress. From the evaluation of three other device isolation processes, A, B and moB, whose active size has $0.45{\mu}m$ in length, moB process is turned out to have the lowest stress value and the smallest bird's beak effect.
