This research is an empirical study to analyze the factors that affect users' acceptance & diffusion of online product message. Today many people use the product message/information on the internet, before they make decision to buy something in online/offline environment. This paper proposes the site design look, enjoyment, and usefulness as message perception factors. And we examine the relationship among the perception factors, message credibility, acceptance & diffusion. The purpose of this paper is threefold. First, we examine the relationship between as perception factors and the credibility assessment of the message by customers. Second, we will show the effect of message credibility on the message acceptance & diffusion. Third, we try to present some theoretical and empirical implication through the result of our studies.

Hydraulic conductivity of unconsolidated media can be determined by aquifer tests, laboratory tests and empirical equations based on grain size analysis. Commonly, the different methods give different hydraulic conductivities. Grain size measurements were done to determine hydraulic conductivity, using 184 soil samples collected from eight boreholes in a riverbank filtration area, Daesan-Myeon, Changwon City, Korea, Pumping tests were conducted at the riverbank filtration area. The average hydraulic conductivity by the empirical relations from grain size measurements comes out around $10^{-2}m/s$, 22 to 55 times higher than by the pumping test analyses. The hydraulic conductivity obtained from the empirical equations is interpreted to have a relationship with steady-state condition while that obtained from the pumping tests is interpreted to have a relationship with unsteady-state condition. Thus, hydraulic conductivity obtained from various methods should be critically analyzed for reasonable management of groundwater development.

This paper investigates the linkages between returns both in foreign exchange and stock markets, and uncertainties in two markets using daily data for the period of 16 July 2004 to 30 June 2014 in Nepalese economy. Four hypotheses are tested about how uncertainty influences the stock index and exchange rates. From the empirical results, a bivariate EGARCH-M model is the best to explain the volatility in the two markets. There is a negative relationship from the exchange rates return to stock price return. Empirical results do provide strong empirical confirmation that negative effect of stock index uncertainty and positive effect of exchange rates uncertainty on average stock index. GARCH-in-mean variables in AR modeling are significant and shows that there is positive effect of exchange rates uncertainty and negative effect of stock index uncertainty on average exchange rates. Stock index shocks have longer lived effects on uncertainty in the stock market than exchange rates shock have on uncertainly in the foreign exchange market. The effect of the last period's shock, volatility is more sensitive to its own lagged values.

Purpose - The operating mechanism between education input and economic growth is a mysterious proposition that has attracted a vast array of scholars' interests to study on it. Therefore, this paper sets China as an example to analyze the dynamic relationship between education input and economic growth. Research design and methodology - The annual time series from 1990 to 2017 will be employed to conduct an empirical analysis under the vector autoregressive model. The education input is treated as an factor that impacts the economic growth such as labor input and capital input. Meanwhile, the education input will be added to the Cobb-Douglas production function to form a new one so as to explore the dynamic relationship between education input and economic growth. Results - According to the results of empirical analysis, it can be found that the education input has an increasingly positive effect on economic growth. Simultaneously, the economic growth also has a positive effect on education input, but this kind of effect is not steady. Of course, the labor input and the capital input also can promote the economic growth to some degree. Conclusions - The education input is one of most important inputs for a country. Based on the empirical analysis, this paper suggests that the China's government should put more emphasis on the education input so to make its economy develop well.

The goal of this study was to investigate the impacts of service quality, customer satisfaction, and switching burier on store loyalty of the clothes shops at large-scale discount stores. The subjects were 357 female adults living in Suncheon City, Jeollanam Province. The questionnaires were conveniently sampled from June 1 to 30, 2006. The collected data were factor and reliability analyzed using the SPSS program. And Regression was used to verify the relationships between the variables. Among the six hypotheses set in the research model, total three were accepted through empirical analysis and the rest three were accepted partially. The empirical results showed the following managerial implications. First, consumer' perceived service quality has relationship with customer satisfaction and store loyalty. Second, service quality has a positive relationship with switch barrier. Third, customer satisfaction has significantly related with switch barrier. Fourth, switch barrier has positively related with store loyalty. Finally, 'sales people', 'VMD/atmosphere', and 'assortment' of the service quality factors have positive relationships with store loyalty, but 'policy' has a negative relationship with store loyalty.

A parametric empirical Bayes procedure is proposed and studied to compare treatments simultaneously with the best. Minimum Bayes risk lower bounds are derived for an additive loss function, and their relationship with Bayesian simultaneous confidence lower bounds is given. For the proposed empirical Bayes procedure, the nominal confidence level both in Bayesian sense and in frequentist's sense is shown to be controlled asymptotically. For practical implementation, a measure of significance similar to f-value is suggested with an illustrative example.

The purpose of this study is to investigate the structural relationship between resort selection attributes, emotional responses, and empirical values of scuba diving participants. The general population who enjoys scuba diving in Korea was selected as the population. Using the convenience sampling method, 553 of the 600 questionnaire samples were extracted as the final valid sample. For data processing, frequency analysis, exploratory factor analysis, and Cronbach's α test were performed using SPSS 23, and confirmatory factor analysis and structural equation model analysis were performed with AMOS 18. The results are as follows: First, among the sub-factors of selection attributes, equipment, facility environment, and diving point showed a positive effect on emotional response, but staff service did not have any significant effect. Second, the emotional response positively affected by the selection attribute showed a positive effect on all factors of service excellence, consumer utility, fun value, and aesthetic value of empirical value. Therefore, scuba diving resort managers must recognize the importance of equipment, facility environment, and diving point among these selection attributes of customers. And to satisfy the customer needs the resort must accurately identify the needs for diving equipment, facility environment and diving point. Various methods for this should be explored through the needs of the identified customers, and efforts should be made to provide safe equipment, comfortable facilities, and various diving points.

The previous studies have investigated the effect of social capital on innovation performance. However, the previous studies investigating the relationship between social capital and innovation performance have assumed a black box in the linkage. According to the knowledge based view, firms with inter-dependent relationship can make innovation through sharing processes of knowledge. In other words, social capital as intangible resource results in knowledge management activities which can increase innovation performance. And increasing innovation can make relationship satisfaction promoting relationship investment gradually. Therefore, research hypotheses are made from social capital to relationship investment. From the empirical results, except for the effect of knowledge sharing on both product innovation and relationship satisfaction, almost all hypotheses are reported to be significant. And product innovation performance positively affects relationship satisfaction, and relationship investment is positively affected by relationship satisfaction. From this study, we can know the importance of knowledge management activities in strategic management view.

While analyzing data, researching outliers, which are out of the main tendency, is as important as researching data that follow the general tendency. In this study we discuss the influence function for outlier discrimination. We derive sample influence functions of sample mean, sample variance, and sample standard deviation, which were not directly derived in previous research. The results enable us to mathematically examine the relationship between the empirical influence function and sample influence function. We can also consider a method to approximate the sample influence function by the empirical influence function. Also, the validity of the relationship between the approximated sample influence function and the empirical influence function is also verified by the simulation of random sampled data in normal distribution. As the result of a simulation, both the relationship between the two influence functions, sample and empirical, and the method of approximating the sample influence function through the emperical influence function were verified. This research has significance in proposing a method that reduces errors in the approximation of the empirical influence function and in proposing an effective and practical method that proceeds from previous research that approximates the sample influence function directly through empirical influence function by constant revision.

Many companies are struggling with the issue of performance measurement because a generally accepted framework does not exist. The Balanced Scorecard is designed to help firms that have historically overemphasized short-term financial performance. In this article, we discuss the interrelation between supply relationship and BSC. The Balanced Scorecard to measure quality performance with respect to supply relationship is suggested. Based on the survey of 84 venture firms, the validity of the measurement tool is tested statistically. Consequently, it was found that the suggested items have validity to measure supply relationship quality performance
