A special government agency has been charged with implementing quality management to guarantee the quality of wild-simulated ginseng. However, these processes are carried out by use of documents, and this has resulted in information omission and high document management costs. To solve this problem, this study analyzed the existing quality management process by using a smart contract for the existing offline form and proposed a new quality management system for storing and managing all log data in the blockchain. This system reduced documentation management costs about quality management and recorded information in the previous step through the quality management steps, thus forming a step-by-step record chain. Experiments were conducted by implementing this system, which improved data integrity and reliability. Additionally, sensitive information, such as personal information, was included in the system by use of the off-chain technology.

Purpose - The main purpose of the current study is to examine the impact of accounting information quality and information asymmetry on the underinvestment phenomenon among the listed companies on the Tehran Stock Exchange (TSE). Research design, data, and methodology - The population includes 94 firms selected through systematic sampling. The data is collected from the audited financial statements of the firms provided by TSE's website from 2010 to 2015. Accounting information quality and information asymmetry is considered as independent variables, and their impact is examined on the dependent variable (underinvestment). Results - The statistical results, based on data collected from 94 listed companies on the TSE during 2010-2015, revealed positive impact of accounting information quality and positive impact of information asymmetry on underinvestment. There was a significant relationship between accrual quality (AQ) and underinvestment, and spread and underinvestment. The results also showed that information asymmetry is the main factor in the creation underinvestment. Conclusions - Findings of this article can assist accounting researchers and theoreticians in comparing Real world facts with hypotheses developed with respect to accounting information quality, information asymmetry and underinvestment. However, the results of fuzzy regression analysis indicate significant relationships between the independent variable except underinvestment.

Information technology and the Internet have had a dramatic effect on education method and individual life. Universities and companies we making large investments in e-Learning applications but are hard to pressed to evaluate the success of their e-Learning systems. e-Learning can be seen as not only one of Internet based information systems which can provide education services but also one of teaching-teaming methods which can implement self-directed teaming. This paper tests the updated model of information system success proposed by Delone and McLean using a field study of a e-Learning. The five dimensions - information quality, system quality, service quality, user satisfaction, net benefit - of the updated model are parsimonious framework for organizing the e-learning success metrics identified in the literature. Questionaires are collected from 107 students who are enrolling a e-learning class using online survey. The model is tested using SPSS and LISREL. The results show that information quality and service quality are significant predictors of user satisfaction with the e-Learning system but system quality is not. Also user satisfaction is found to be a strong predictor of the learning performance. This strong association between user satisfaction and teaming performance suggests that user satisfaction may serve as a valid surrogate for teaming performance. Empirical testing of the updated DeLone & McLean model should therefore be extended to cover a wider variety of systems.

As service firms continue to seek unique sources of sustainable competitive advantage, service quality has been discussed as a potential alternative to traditional skills and sources. The information of customers is generally believed to be a key component in creating corporate responsiveness to customer requests. In order to develop and maintain long-term close relationships with customers(CRM), service firms need to build an effective and ongoing service quality information system(SQIS). Service firms that formally collect customer-related information and internal service quality information were to be more responsive. The purpose of the present study is twofold. 1. How to nicely get the information on the service quality. 2. How to build a SQIS. One of numerous examples from financial service-sector firms is given to show that SQIS can be developed to improve service quality. This paper investigates SQIS of a Korean commercial bank as an example. Implications and strategies for building an effective SQIS for financial service-sector firms are discussed, and directions for future research are indicated.

In this paper, we analyze the quality status of Health and Welfare division's standardized log and asses the characteristics of the institutions' logs analysis to establish the criteria to minimize hazards and control the quality of log's institutional details to limit extraction. As a result, extraction condition's proposed development direction to adequately assess and control health and welfare abuses privacy control target log. This improvement over the status and quality of information shared with relation to institutional work of the log quality characteristics is made possible. In addition, quality control and inspection standards were prepared in accordance with the institutional log characteristics. Future research will include performing continuous analysis and improvement activities on the quality of logs with integrated control of sharing personal information and distributing information about logs' quality to proactively target organ. Therefore, we expect that correcting proactive personal information misuse and leakage is possible to achieve.

This study examined the perception and behavior of fast food restaurant customers toward ordering kiosk nutrition information. Specifically, the influence of nutrition information transparency and information quality on behavioral intention and revisit intention were identified. In addition, the difference in the nutrition information transparency and information quality was analyzed according to the health consciousness of the customers. The study employed a self-administered survey that was distributed both online and offline from November 8~22, 2018. The sample of the study was customers who had experienced ordering from the kiosk in a fast food restaurant in the six months prior to taking the survey. A total of 250 (98.0%) respondents completed the survey, which was used for data analysis. As a result, there was a significant relation between transparency and nutrition information quality (P<0.001). The higher the visibility and inferability of the nutrition information, the better the nutrition information quality. Nutrition information quality has a significant impact on the levels of customer satisfaction and revisit intention (P<0.001). For the differences in the transparency and nutrition information quality by health consciousness of customers, the results indicated that groups with high health consciousness (3.74 or higher) perceived a higher transparency and nutritional information quality than those with a lower health consciousness. These findings can form the basis of a strategy in developing nutrition information of ordering kiosks in restaurants. In addition, it can be applied to academia and industry.
