Recently, with the growing of social network sites, people's choice is also getting more and more. So the notion of loyalty has become an important construct within the Social Network framework because of member is easy switching on the social networking sites. Despite the increasing importance of social network sites loyalty question, there's very little research in this area. In electronic commerce, the website loyalty development process is based on both website satisfaction and website trust toward the net-enabled business. But how to target the members with high or low loyalty in the social network sites is still a question. In this paper we propose one improved RFM model to evaluate the member loyalty to find the potential members for improving the service quality of the social network site. In addition, an empirical case study is performed to demonstrate how this procedure works. Moreover, further applications of this research are provided for improved social network sites experiences and how to use the model to practice.

In this paper, we investigated the satisfaction of incorporation founder through the Startbiz System. We also expected that the research results contribute to draw the development plan of Startbiz System afterward. The satisfaction in the Startbiz System was investigated in four dimensions such as the company establishing service, the website quality, the business promotion environment of the associated organizations, and providing information. The satisfaction appeared for the order of the company establishing service, providing information, the website quality, and the business promotion environment of the associated organizations. It's necessary to improve of the business promotion environment of the associated organizations for activating an incorporation utilizing the Startbiz System.

Purpose: To continuously monitor soil and climatic properties, a data acquisition system (DAQ) was developed and tested in plum farms (Gyewol-ri and Haechang-ri, Suncheon, Korea). Methods: The DAQ consisted of a Raspberry-Pi processor, a modem, and an ADC board with multiple sensors (soil moisture content (SEN0193), soil temperature (DS18B20), climatic temperature and humidity (DHT22), and rainfall gauge (TR-525M)). In the laboratory, various tests were conducted to calibrate SEN0193 at different soil moistures, soil temperatures, depths, and bulk densities. For performance comparison of the SEN0193 sensor, two commercial moisture sensors (SMS-BTA and WT-1000B) were tested in the field. The collected field data in Raspberry-Pi were transmitted and stored on a web server database through a commercial communications wireless network. Results: In laboratory tests, it was found that the SEN0193 sensor voltage reading increased significantly with an increase in soil bulk density. A linear calibration equation was developed between voltage and soil moisture content depending on the farm soil bulk density. In field tests, the SEN0193 sensor showed linearity (R = 0.76 and 0.73) between output voltage and moisture content; however, the other two sensors showed no linearity, indicating that site-specific calibration is important for accurate sensing. In the long-term monitoring results, it was observed that the measured climate temperature was almost the same as website information. Soil temperature information was higher than the values measured by DS18B20 during spring and summer. However, the local rainfall measured using TR 525M was significantly different from the values on the website. Conclusion: Based on the test results obtained using the developed monitoring system, it is thought that the measurement of various parameters using one device would be helpful in monitoring plum growth. Field data from the local farm monitoring system can be coupled with website information from the weather station and used more efficiently.

With the advancement of information and communications technologies and the universal dissemination of smartphones, ICT-utilizing education is also getting the limelight. In the recent ICT-utilizing education, teachers and learners produce massive digital data by consulting massive information on the Internet, and the produced data is filtered in the process of education and utilized for the current and next educational programs. In order to construct the data well-suited for education from massive data available on the Internet, it is important to verify the quality of the educational data. To this end, we propose an educational website that can provide the data satisfying visual needs demanded by learners in terms of utilizing a digital curation system. In this paper, we also present a design and implementation of the website that non-ICT majors can easily use, which in turn enables them to conduct the education of creative personality utilizing image and video contents.

This study aims to examine the factors that affect customer satisfaction and repurchase intention of online shoppers in Vietnam. We used the anklet method to collect information by sending the online questionnaire to Vietnamese people via social media like Facebook, Zalo, and instructed participants to fill out the survey. This study collected data randomly from 597 Vietnamese individuals who have experienced online shopping. Applying both qualitative and quantitative methods, we investigated the impacts of factors (responsiveness, trust, convenience, delivery, information quality and perceived website usability) on customer satisfaction and repurchase intention. The results revealed that: (1) Information quality, delivery, convenience, and perceived website usability have the most significant impacts on customer satisfaction and intention, (2) Trust moderately affects satisfaction and repurchase intention, (3) Responsiveness has no significant influence on repurchase intention and (4) Control variables, included gender and marital status also impacted satisfaction and repurchase intention because the study found that male customers are more satisfied than female customers and single people tend to repurchase at familiar websites more than the other people. The findings suggested that six mentioned factors have different levels of impacts on customer satisfaction and repurchase intention; moreover, the demographic factors also affect satisfaction and intention to repurchase.
