Are intentions important in deciding the outcome of an action such as sharing misinformation among social media users during the pandemic? What is their role and how far they are important for the very act of fake sharing news? The social media users' actions on the social platform are determined by what they plan to do themselves; however, their motivation has an immense role to play in the dissemination of fake news on social media. The study proposes a conceptual model for understanding how select factors affect fake news sharing motivation and intentions of social media users. The study scrutinizes the relationship between content and context, fear of missing out (FoMO), news verification and news sharing gratification on the motivation and intention of social media users of networked Asian society. Empirical Data were drawn from social media users (N = 243) from India, using an online questionnaire based on prior studies and structural equation modeling (SEM) approach was used to analyze the data collected. Results indicate that news content, news verification, and news sharing gratification have a direct and positive relationship with sharing motivation. On the other hand, news context and content, FoMO and news sharing gratification have a positive significant relationship with sharing intention. Likewise, it was discovered that news verification will decrease sharing intention of the social media users. However, news context, that is the pandemic in the case of the present study and FoMO were not identified as determinant variables for sharing motivation among social media users. The research limitations and further scope were discussed.

Purpose - Korea became a trillion-dollar trading country in 2011. With the exponential increase in Korea's trade volume over the past decades, trade-related administrative burdens per capita for Korea Customs became enormous, for which the government established the Single Window, a trade-facilitating system, in 2004 to enhance the efficiency of customs-clearing procedures for traders. This paper focuses on finding whether the Korean Single Window system affects the country's trade facilitation positively through an empirical methodology. Design/methodology - To find empirical evidence that Single Window affects trade facilitation for the customs-clearing procedure, this study assumes that a time-efficient environment enables the handling of the increase in trade volume, under which four independent variables related to import customs-clearing procedures and two dependent variables to import were adopted for empirical analysis. The import customs procedures are classified into four steps from port entry to declaration acceptance. To understand the relationship between variables, scattered plots and correlation coefficients were calculated. Eight hypotheses were set and underwent simple linear regression. The data for analysis were collected by Korea Customs, and were about the lead time of import, the volume of imports in million USD, and the number of import declarations reported to customs offices on a monthly basis from 2005 to 2013. Findings - Six of the eight hypotheses showed the statistically significant result that lead time in the import customs-clearing procedure positively affects the number of import declaration reports and import volume. Specifically, Hypothesis 1, Hypothesis 2, and Hypothesis 3 strongly support the assumption lead time in import customs declaration has an inverse relationship with the number of import declarations, which means that the shorter the import lead time, the more import declaration increases. Research Limitations/Implications - With limited data accessibility to the government's custom-sclearing procedures, only the import lead time for customs clearance were adopted as independent variables. This paper, however, successfully found that the Single Window system contributed to trade facilitation. Originality/value - This study found that the time-saving Single Window system of Korea Customs enables itself to manage an exponentially-increasing trade volume by creating a trade-facilitating environment for customs personnel and traders, which may be a unique implication found through quantitative methodology.

The purpose of this study was to verify (i) a consistent calibration verification for the assessment of method linearity and (ii) calibration agreement with calibration settings. We validated calibration verification through method linearity with different lot number of individual calibrators that span the working range for 9 tests except salicylate with control sample in test. We evaluated that it covered broad analyte range to assay from near zero to the top of the measuring range with 5 or 6 points every three times for 10 analytes in TDM test. Target values were plotted on X-axis with assigned or observed values on the Y-axis. Working range were as follows. Calibration verification of the measuring range (maximum to minimum values) has been validated asetaminophen 0.1 to $304.6_{\mu}g/mL$, salicylate 0 to $1005_{\mu}g/mL$, valproic acid 3.2 to $154.19_{\mu}g/mL$, digoxin 0.17 to 5.65 ng/mL, vancomycine 1.3 to $80.51_{\mu}g/mL$, carbarmazepine 0.1 to $22.3_{\mu}g/mL$, phenytonin 0.6 to $40.21_{\mu}g/mL$, theophyline 0.2 to $40.21_{\mu}g/mL$, primidone 0 to $24.07_{\mu}g/mL$, phenobarbital 0.6 to $60.0_{\mu}g/mL$. Drawing a straight line through five or six points of these data showed good linearity. We are sure that it is important to assess the calibration verification of a test method to ascertain the lowest and highest test results that are reliable.

In this study, we conducted verification of key influencing factors during cone penetration testing using the developed Mini Cone Penetration Tester (Mini-CPT), and compared the experimental results with empirical formulas to validate the equipment. The Mini-CPT was designed to measure cone penetration resistance through a Strain Gauge, and the resistance values were calibrated using a Load Cell. Moreover, the influencing factors were verified using a model ground constituted in a soil box. The primary influencing factors examined were the boundary effect of the soil box, the distance between cone penetration points, and the cone penetration speed. For the verification of these factors, the experiment was conducted with the model ground having a relative density of 63.76% in the soil box. It was observed that the sidewall effect was considerably significant, and the cone penetration resistance measured at subsequent penetration points was higher due to the influence between penetration points. However, within the speed range considered, the effect of penetration speed was almost negligible. The measured cone penetration resistance was compared with predicted values obtained from literature research, and the results were found to be similar. It is anticipated that using the developed Mini-CPT for constructing model grounds in the laboratory will lead to more accurate geotechnical property data.

The necessity of an empirical study on how projection mapping videos are evaluated from consumers' point of view has arisen, as they can lead to visual pollution if factors including spatial characteristics around the structure and details of the contents are not taken into consideration. This study aims to evaluate projection mapping videos and elucidate the question on whether evaluation criteria positively influence the satisfaction level or not. Above all, five evaluation criteria including artistry, creativity, identity, immersion and usefulness were deducted and a hypothesis from preceding research "each evaluation criteria will positively(+) influence the satisfaction level of projection mapping video" has been established. In order to test the hypothesis, big domestic department stores which screened projection mapping videos were selected and a verification experiment has been conducted with ordinary citizens as subjects. In the result of the experiment, among the five evaluation criteria, artistry, creativity, and usefulness were chosen, while identity and immersion were dismissed. The result verifies that if useful information is provided in forms of interesting contents produced with distinctive ideas and creative methods, it will satisfy the consumers as attractive public design.

Purpose: This study is to analyze the relationship between leadership, empowerment, organizational commitment, and nursing performance. Method: The method of the study is the establishment of the analytical framework of the theoretical model and the hypotheses for the empirical survey, analysis of the data collected by the empirical survey, and the provision of a revised model explaining more clearly the causal relationship between variables. Result: Transformational leadership has greater influence on empowerment and nursing performance than transactional leadership. Self determination and impact of empowerment factors greatly influence on organizational commitment, competence and impact significantly influence on nursing performance, and organizational commitment is closely related to the general nursing affair, the human relationship, and the job as an organizational member. Transactional and transformational leadership, in provision of the revised model by verification of goodness-of-fit of the hypothetical model, affects all parts of nursing performance by intervening competence and self determination of empowerment factors. Especially, transactional leadership directly influences on nursing performance without intervening the empowerment factor. Conclusion: The conclusion of the study is transformational leadership exerts a more positive influence on empowerment, organizational commitment, and nursing performance than transactional leadership.

As the important breakthrough continues in the field of machine learning and artificial intelligence recently, there has been a growing interest in the analysis and the utilization of the big data which constitutes a foundation for the field. In this background, while the economic value of the data held by the corporates and public institutions is well recognized, the research on the evaluation of its economic value is still insufficient. Therefore, in this study, as a part of the economic value evaluation of the data, we have conducted the economic value measurement of the data generated through the small business guarantee program of Korean Federation of Credit Guarantee Foundations (KOREG). To this end, by examining the previous research related to the economic value measurement of the data and intangible assets at home and abroad, we established the evaluation methods and conducted the empirical analysis. For the data value measurements in this paper, we used 'cost-based approach', 'revenue-based approach', and 'market-based approach'. In order to secure the reliability of the measured result of economic values generated through each approach, we conducted expert verification with the employees. Also, we derived the major considerations and issues in regards to the economic value measurement of the data. These will be able to contribute to the empirical methods for economic value measurement of the data in the future.
