Properly designed and well-executed services enable e-commerce companies to capture the unique needs and preferences of customers, help them build customer loyalty, and thereby, strengthen their competitiveness in the marketplace. An object of this study is the new open-market company and it has only 3 percent of the market share. Therefore, it is needed to raise the market share by improving the service qualities. This article presents a six sigma project for service quality improvement in the open-market company. This study was carried out based on five steps of DMAIC which is six sigma technique. First, a defect rate was defined as unsatisfaction rate. In addition, 50-people data was analyzed and it was shown that the defect level was 2.5 sigma level. In this study, in order to raise the sigma level, novel eight action items were determined based on SIPOC, FDPM, cause and effect diagram, matrix chart, Pareto chart and statistical analysis.

In this paper a space search technique is used to detect and locate the faults of the circuit interconnections. The circuit interconnections are represented by the tree structure and the tree space is searched to detect and locate the open faults of the circuit interconnections. The breadth search is used to detect the open faults and reduce the space size. The depth search is used to locate the open faults.

The standardization of third Generation Partnership Project(3GPP) has been performed in of order to support interactive multimedia services under mobile environments. In this 3GPP, transmit diversity solutions are applied to increase the available diversity effectively using 2 or more antennas. In this paper, we analyzer the performances on STTD(Space Time Transmit Diversity) technique and its modified techniques such as STTD-OTD, CL-STTD, and 4TX-STTD out of open loop transmit diversities that the standardization of 3GPP has released. We also propose the open loop transmitter and receiver diversities to add the receiver diversity. We analyze and discuss the performance of the proposed techniques and using the Matlab simulation under the flat fading channel environment.

A Korean water deer was rescued after being hit by a motor vehicle. Clinical and radiographic examination revealed a grade III open fracture of the right metacarpus with severe soft tissue injury. The water deer underwent closed reduction of the fracture, which was stabilized by the application of the Ilizarov method of 4-ring circular external skeletal fixation (CESF) as a minimally invasive technique. The water deer was successfully released into the wild. CESF was advantageous for the stabilization of open comminuted fracture and the management of a severely contaminated wound in a Korean water deer. CESF can be used successfully in wild deer with good tolerance and minimal complications.

In this paper, we study learning process mining and analytic technology based on open education platform. A study on mining through personal learning history log data based on an open education platform such as MOOC which is growing in interest recently. This technology is to design and implement a learning process mining framework for discovering and analyzing meaningful learning processes and knowledge from learning history log data. Learning process mining framework technology is a technique for expressing, extracting, analyzing and visualizing the learning process to provide learners with improved learning processes and educational services.

Purpose: This study aims to analyze the effects of Brand Coolness, Brand Love, and Self-brand Connections on Word-of-mouth positively. The retail format of Starbuck in Vietnam is successful in distribution applied when it becomes the place for customers to express themselves. Consumers are now aware about Brand Coolness of the Starbucks developed in Vietnam then turn to love the brand of store and connect themselves to the brand. In this study, the closest relationship to form the basis for consumer Word-of-mouth about a brand is the relationship between Brand Coolness and Brand Love. Results: The findings show that Brand Coolness and Brand Love are important value factors in customers' minds toward their behavior, form there, it will contribute to the brand store in distribution. Research design, data and methodology: This article used the quantitative technique utilizing PLS-SEM software to test the hypothesis with 600 samples. The data obtained shows that people have Word-of-mouth about the retail format of Starbucks in Ho Chi Minh City. Conclusion: The study has demonstrated the conclusions and proposed solutions to help beverage brands build Brand Love, thereby achieving coolness, connecting brands with themselves, leading to customer Word-of-mouth in a positive way towards retail format.

Ethnocentrism in users plays an important role in predicting user behavior when deciding between imported and domestic goods. The purpose of this study is to look into the influence of ethnocentrism in customer behavior on brand image, perceived value, perceived quality, brand trust, and brand buy intention. Vietnamese customers prefer homegrown brands. The moderate role of consumer ethnocentrism in the conceptual framework emphasizes the country origin of the product is the most important factor. It also demonstrates how the intention of Vietnamese consumers to buy domestic brands is substantially influenced. To test the hypothesis, this article used a quantitative technique utilizing PLS-SEM software. With 917 samples, the study used the quota sampling approach to collect data from students at 10 universities in Ho Chi Minh City. The data suggest that all players have a positive association and that consumer ethnocentrism has a moderate impact in the Vietnamese brand context. Following that, suggestions are made to help Vietnamese firms create and retain their brands in the face of severe competition from global brands in the domestic market. To increase consumer intent in purchasing behavior, the Vietnamese local company needs to establish a strong brand.

This study explores the linear and nonlinear solutions of sigmoid functionally graded material (S-FGM) nanoplate with porous effects. A size-dependent numerical solution is established using the strain gradient theory and isogeometric finite element formulation. The nonlinear nonlocal strain gradient is developed based on the Reissner-Mindlin plate theory and the Von-Karman strain assumption. The sigmoid function is utilized to modify the classical functionally graded material to ensure the constituent volume distribution. Two different patterns of porosity distribution are investigated, viz. pattern A and pattern B, in which the porosities are symmetric and asymmetric varied across the plate's thickness, respectively. The nonlinear finite element governing equations are established for bending analysis of S-FGM nanoplates, and the Newton-Raphson iteration technique is derived from the nonlinear responses. The isogeometric finite element method is the most suitable numerical method because it can satisfy a higher-order derivative requirement of the nonlocal strain gradient theory. Several numerical results are presented to investigate the influences of porosity distributions, power indexes, aspect ratios, nonlocal and strain gradient parameters on the porous S-FGM nanoplate's linear and nonlinear bending responses.

Intellectual structure analysis, which quantitatively identifies the structure, characteristics, and sub-domains of fields, has rapidly increased in recent years. Analysis techniques traditionally used to conduct intellectual structure analysis research include bibliographic coupling analysis, co-citation analysis, co-occurrence analysis, and author bibliographic coupling analysis. This study proposes a novel intellectual structure analysis method, Keyword Bibliographic Coupling Analysis (KBCA). The Keyword Bibliographic Coupling Analysis (KBCA) is a variation of the author bibliographic coupling analysis, which targets keywords instead of authors. It calculates the number of references shared by two keywords to the degree of coupling between the two keywords. A set of 1,366 articles in the field of 'Open Data' searched in the Web of Science were collected using the proposed KBCA technique. A total of 63 keywords that appeared more than 7 times, extracted from 1,366 article sets, were selected as core keywords in the open data field. The intellectual structure presented by the KBCA technique with 63 key keywords identified the main areas of open government and open science and 10 sub-areas. On the other hand, the intellectual structure network of co-occurrence word analysis was found to be insufficient in the overall structure and detailed domain structure. This result can be considered because the KBCA sufficiently measures the relationship between keywords using the degree of bibliographic coupling.
