The purpose of study was to test the effects of service quality of regional festivals showing the characteristics of convergence service and perceived value of visitors on intention of word-of-mouth, and the moderating role of perceived value between service quality and intention of word-of-mouth. For this empirical study, the data were collected and selected from 320 residents in Wonju province and visitors for Wonju Hanji Cultural Festival from all around from the South Korea by using structured questionnaires. The data were analyzed by hierarchical regression technique. The results showed that both of 7 factors of service quality of regional festivals and 2 factors of perceived value had a positive effect on visitors' intention of word-of-mouth. And also found out the only one out of two perceived value factors, namely 'non-monetary value' had the moderate roles between service reliability out of 7 service quality factors and intention of word-of-mouth. The results of study was summarized and theoretical implications of the findings with practical applications were discussed. After then, the directions for further study were presented based on the limitation of this one.

It has been known that Golf course could impose negative impacts on water-ecosystem if pollutant-laden runoff is not treated well. It is important to control non-point source and re-use treated wastewater from the golf course to secure water quality of receiving waterbodies. At golf courses, the rainfall-runoff is affected by various practices to manage grasses. In many hydrological modelings, especially in simple rainfall-runoff modeling, effects on runoff of plant growth and cutting are not considered. In the study, the water erosion prediction project (WEPP), capable of simulating plant growth and various management, was evaluated for its runoff prediction from golf course under grass cutting and irrigation. The %Difference, $R^2$ and the NSE for runoff comparisons were 1.15%, 0.93 and 0.92 for calibration, and 18.12%, 0.82 and 0.88 for validation period, respectively. In grass cutting scenario, grass height was managed to be 18~25 mm. The estimated runoff was decreased by 27%. The difference in estimated total runoff was 11.8% depending on irrigation. As shown in this study, if grass management and irrigation are well-controlled, water quality of downstream areas could be obtained.

It was announced that 'making a better wellbeing city program' is a new core quality of life policy of Roh Mu-Hyun government. The policy is comprehended as a sign of regional policy changeover, that give empathize to human ware oriented governance from hard ware oriented physical elements input policies. To be effective, It is important to introduce a institutionalization of dynamic social relations in regional community such as participations of civil society. In the case study of Jinju city, a medium scale city located in southern part of Korean peninsular, Invitation of the innovation city, initiated by the alliance of city government and growth coalition, was making progress. Through alliance of labor unions and citizen associations, the public management of public bus companies were succeeded. But the restoration of historical places were suffered a setback by conflicts of interests with development profits. In these contexts, it is insisted that the core of 'making a better welling being city program is introducing of human ware oriented regional policies, such as institutionalization of citizen associations participation.

The quality attributes of coffee treated with different concentrations of white ginseng extract were examined. Increased concentration of white ginseng extract was associated with higher color values (Hunter L. a, b scale). The crude saponin contents of untreated roasted coffee beans (control) and those coated with $5^{\circ}$ Brix (WGC-1) and $20^{\circ}$ Brix white ginseng extract (WGC-2) were 8.29%, 8.74%, and 8.93%, respectively. The total ginsenoside contents of WGC-1 and WGC-2 were 0.3 mg/g and 0.6 mg/g, respectively. In the case of major ginsenosides, the contents of ginsenosides $Rg_1,\;Rg_2,\;Rb_1,\;Rb_2,\;Rg_2,\;Rh_1$, and $Rg_3$ increased directly with the concentration of white ginseng extract. Total sugar and acidic polysaccharide contents also increased directly with the concentration of white ginseng extract. The coffee beans coated with ginseng extract scored significantly higher ginseng taste scores than the control (p<0.005) in sensory evaluation. In terms of coffee taste, WGC-2 had significantly lower scores than the commercial coffee bean. In the consumer sensory evaluation, overall preference did not differ significantly among the treatments.

Project management is a current trend of management in the public sphere, based on different principles, methods and tools. The tools include information technologies providing control over time, cost, quality and planning process in order to ensure accountability to interested parties. The goal of the research was to examine the impact of the integration of information systems in project management of the public sphere on the quality of public governance and administration using the example of infrastructure projects involving the private sector in developing countries. The methodology of the research is based on the concepts of "digital-era governance" (DEG), "Information governance" and "project governance" to determine the effectiveness of information systems and technologies in the management of infrastructure projects in the public sphere. The data from the countries with Lower middle income (India, Indonesia, Philippines, Ukraine, Vietnam) and Upper middle income (Argentina, Brazil, China, Colombia, Mexico, Peru, Romania, Russian Federation, Thailand, Turkey) for 1996-2020 were used to study the effects of DEG. The results show two main trends in the countries with Lower middle income and Upper middle income. The first trend is the development of digital governance, the concept of "digital-era governance" through information systems and performance measurement of the governance system, forecasting of investment flows of infrastructure projects, measurement of payback and effectiveness parameters for investment management in the public sector, decision support. The second trend is the existence of systemic challenges related to corruption, social and institutional factors through the development of democracy in developing countries and the integration of NPM similar to developed countries. The confidence of interested parties, especially private investors, in public authorities is determined by other factors - the level of return on investment, risks and assignment of responsibility, probability of successful completion of the project. These data still remain limited for a wide range of project participants, including citizens.

Background: In 2006 Emergency Medical Services Index (EMSI), which summarizes the performance of regional emergency medical services system, was developed. This study assesses the performance of the EMSI to help determine whether EMSI can be used as evaluation tool. Methods: To build a composite score of the EMSI from predefined 24 indicators, 3 normalized values were calculated for each indicator, the normalized values of each indicator were weighted using 4 weighting methods, and the weighted values were aggregated into the final composite score using 2 aggregation schemes. The performance of EMSI was evaluated using 3 criteria: discrimination, construct validity, and sensitivity. Discrimination was the proportion of regions that did not include the overall median rank in the 5th to 95th percentiles rank interval, which was calculated from Monte Carlo simulation. Construct validity was a correlation among the alternative EMSIs. Sensitivity of EMSIs was evaluated by total shift of quartile membership and changes of 5th to 95th percentile intervals. Results: The total discrimination performance of the EMSI was 50.0%. Correlation coefficients between EMSIs using standardized values and those using rescaled values ranged from 0.621 to 0.997. Variation of the quartile membership of regions ranged from 0.0% to 75.0%. The total change in the 5th to 95th percentile intervals ranged from -19 to +17 places. Conclusion: The results suggested that the EMSI could be used as a tool for evaluating quality of regional EMS system and for identifying the areas for quality improvement.

Quantitative assessment on the impact from North Korean emissions to surface particulate matter(PM) concentration in the Seoul Metropolitan Area (SMA), South Korea is conducted using a 3-dimensional chemistry transport model. Transboundary transport of air pollutants and their precursors are important to understand regional air quality in East Asian countries. As North Korea locates in the middle of main transport pathways of Chinese pollutants, quantifiable estimation of its impact is essential for policy making in South Korean air quality management. In this study, the Community Multiscale Air Quality Modeling System is utilized to simulate regional air quality and its sensitivity, using the Comprehensive Regional Emissions inventory for Atmospheric Transport Experiment 2015 and the Clean Air Policy Support System 2013 emissions inventories for North and South Korea, respectively. Contributions were estimated by a brute force method, perturbing 50% of North and South Korean emissions. Simulations demonstrate that North Korean emissions contribute $3.89{\mu}g/m^3$ of annual surface PM concentrations in the SMA, which accounts 14.7% of the region's average. Impacts are dominant in nitrate and organic carbon (OC) concentrations, attributing almost 40% of SMA OC concentration during January and February. Clear seasonal variations are also found in North Korean emissions contribution to South Korea (and vice versa) due to seasonal characteristics of synoptic weather, especially by the change of seasonal flow patterns.
