<em><span><em>This research is motivated by the growing of online businesses that have an impact on decreasing income of retail businesses. In order to survive, a retail  business have to implement strategies that can increase purchases and provide satisfaction to consumers. This study aims to determine the effect of location, service, product quality, emotional value, and interior design variables on purchasing decisions and also customer satisfaction for increasing purchases, and testing the effect of purchasing decisions on customer satisfaction at Gardena Department Store &amp; Supermarket. This type of research uses quantitative descriptive. The sampling method is non-probability sampling and using purposive sampling technique. The data that have been collected then analyzed using the statistical hypotheses test method consist of multiple linear regression analysis, t-test, and f-test. The partial results of the study indicate that the location, service, and product quality variables have positive and significant effects on purchasing decisions and customer satisfaction. While the emotional value and interior design variables have no partial effects on purchasing decisions and consumer satisfaction. Purchasing decisions has a significant positive effect on customer satisfaction. Simultaneously, the variables of location, service, product quality, emotional value, and interior design have positive and significant effects on purchasing decisions and customer satisfaction at Gardena Department Store &amp; Supermarket. The results of this study can be used as an implication for company management that should continue to improve service, product quality, and need to pay attention to location, especially access and large parking lots so that consumers decide to make purchases and get satisfaction from the products, resulting an increase in consumer purchases at Gardena Department Store &amp; Supermarket.</em></span></em>

Processing Techniques

The Global Positioning System is extensively used in the various context and location service-based applications. Any kind of abnormalities requires an efficient and suitable pre-processing algorithm to be implemented on the data which provides accurate results when used in the application synchronizations. This paper illustrates a framework for various pre-processing techniques applied to the real-time GPS data and its effect on trajectory mapping. The technique used includes Prioritized pattern-based, Savitzky-Golay filtering, outlier elimination, de-trending, and coefficient correlation. The performance assessment of methods discussed in this study is calculated in terms of accuracy with the original and re-created trajectory after the pre-processing and found that the best result is given by moving window method.

In light of the long-term pressure and short-term impact of economic and technological globalization, regional and urban resilience has become an important issue in research. As a new organizational form of regional urban systems, the resilience of urban networks generated by flow space has emerged as a popular subject of research. By gathering 2017 data from the Baidu search index, the Tencent location service, and social statistics, this study constructs information, transportation, and economic networks among 344 cities in China to analyze the spatial patterns of urban networks and explore their structural characteristics from the perspectives of hierarchy and assortativity. Transmissibility and diversity were used to represent the resilience of the network structure in interruption scenarios (node failure and maximum load attack). The results show the following: The information, transportation, and economic networks of cities at the prefecture level and higher in China exhibit a dense pattern of spatial distribution in the east and a sparse pattern in the west; however, there are significant differences in terms of hierarchy and assortativity. The order of resilience of network transmissibility and diversity from strong to weak was information, economic, transportation. Transmissibility and diversity had nearly identical scores in response to the interruption of urban nodes. Moreover, a highly heterogeneous network was more likely to cause shocks to the network structure, owing to its cross-regional urban links in case of disturbance. We identified 12 dominant nodes and 93 vulnerable nodes that can help accurately determine the impetus behind network structure resilience. The capacity of regions for resistance and recovery can be improved by strengthening the construction of emergency systems and risk prevention mechanisms.
