Purpose - The purpose of this study is to examine the gravity model commonly used for demand forecasting upon the implementation of new tourist facilities and analyze the main causation of forecasting errors to provide a suggestion on how to improve. Design/methodology/approach - This study first measured the errors in predicted values derived from past feasibility study reports by examining the cases of five national science museums. Next, to improve the predictive accuracy of the gravity model, the study identified the five most likely issues contributing to errors, applied modified values, and recalculated. The potential for improvement was then evaluated through a comparison of forecasting errors. Findings - First, among the five science museums with very similar characteristics, there was no clear indication of a decrease in the number of visitors to existing facilities due to the introduction of new facilities. Second, representing the attractiveness of tourist facilities using the facility size ratio can lead to significant prediction errors. Third, the impact of distance on demand can vary depending on the characteristics of the facility and the conditions of the area where the facility is located. Fourth, if the distance value is below 1, it is necessary to limit the range of that value to avoid having an excessively small value. Fifth, depending on the type of population data used, prediction results may vary, so it is necessary to use population data suitable for each latent market instead of simply using overall population data. Finally, if a clear trend is anticipated in a certain type of tourist behavior, incorporating this trend into the predicted values could help reduce prediction errors. Research implications or Originality - This study identified the key factors causing prediction errors by using national science museums as cases and proposed directions for improvement. Additionally, suggestions were made to apply the model more flexibly to enhance predictive accuracy. Since reducing prediction errors contributes to increased reliability of analytical results, the findings of this study are expected to contribute to policy decisions handled with more accurate information when running feasibility analyses.

According to the labor related data from Korea Occupational Safety & Health Agency, accident victims of construction industry are increasing 6% annually since 2006. The major reason why the rate of accidents increases in Korea is that lots of labor working with another trades works simultaneously in various type of works. This study analyzes the current accident status in view of the type of building, type of works, and project size for the latest 3 years (2007~2009). As a result, 'single family & semi-detached houses' has the largest number of accidents among buildings. In addition, 'finishing work' shows the highest number in terms of work type. For the size, accidents occurred much for 'less than 300 million'. The results of this study can be used to focus on managing the highly hazardous area where the construction accidents mostly occur; therefore, it is anticipated to contribute to improve efficiency of safety management.

The purpose of this study was to investigate workers' perception on the quality improvement of Korean restaurants for the globalization of Korean food. A total of 342 workers at Korean restaurants in Seoul and Gyeonggi province were surveyed using a self-administrated questionnaire. Excluding responses with significant missing data, 250 responses were used for data analysis. In terms of the improvement of service quality attributes, the 'sanitation management (4.51)' category received the highest score, followed by 'service skill (3.93)', 'menu development (3.90)', 'serving method (3.88)', 'facility and ambiance (3.84)', and 'food taste (3.40)'. There were significant differences of workers' perception on the improvement of service quality which were 'menu development (p<0.01)', 'service skill (p<0.001)', 'facility and ambiance (p<0.001)', and 'sanitation management (p<0.01)' by restaurant operation type, and 'service skill (p<0.001)' and 'facility and ambiance (p<0.001)' by workers' position. The mean score of each service quality category showed that Korean restaurants managed by a franchisor were ranked the highest. In each service quality category, the items which showed the highest scores for the improvement were 'developing the finest cuisine (4.08)', 'providing food seasoning according to customer requests (3.70)', 'proving ladles, tongs, and extra plates which enable customers to take as much food as they want (4.12)', 'staff's ability to explain menu (4.08)', 'using tableware appropriate to each dish (4.03)', 'sanitary management of the provided tableware (dishes, spoons and knives) (4.57)', and 'thorough toilet management (4.57)'. This research suggests that Korean restaurants need to improve service quality to globalize Korean food, and the strategies for service quality management should be developed to be applied to each restaurant operation type.

The waste water treatment facility at rural and mountainous region in catchment areas of dams should be small scale. The wastewater treatment facility of small scale has some specification as follows;1)simple process, 2)low maintenance cost, and 3)high removal efficiency. So, we developed the bioreactor which can be satisfied with the specification of small scale waste water treatment facility. The bioreactor consisted of the anoxic and oxic zone. The two zones were effectively separated by cone type baffle. By the effective separation through CTB, the nitrification and denitrification reaction occurred effectively. Therefore, the removal efficiency of total nitorgen (TN) increased compared to other types of baffle. And, we put into the bio activated media in oxic zone to increase the concentration and activity of microbiology. The media contained the components which were made of many kinds of the minerals to increase the activity of microbiology. Additionally, we observed that the phosphate removal efficiency increased by bio activated media. This is resulted from the coagulation-sedimentation reaction by mineral in components. The average removal efficiencies of TN and TP during Run 2 were 69 and 89% which were 4 and 25% higher than those during Run 1 without the MA, respectively. For BOD, COD, SS and TKN, the average removal efficiencies at Run 2 were slightly higher than those at Run 1. Therefore, we could maintain the high concentration and high activity of microbiology through bioreactor developed in this study. And the removal efficiency of TN and TP increased.

The number of fabrication shop for spherical type LNG tank is proportional to that of the tank radius to be constructed. Due to limitation of facility investment including building sites, it is practically difficult to fabricate various size tanks with perfectly spherical shape in the yards. The efficient method to be capable of increasing cargo tank volume is to extend vertically the conventional spherical type LNG tank by inserting a cylindrical shell structure. The main purpose of this study is to derive related equations on forces generated on spherical type LNG tank with central cylindrical part under various static loadings in order to establish the simplified analysis method for the initial estimate. In this study, equations on circumferential and meridional force have been derived and verified by relations with the reaction forces per unit length of equator.

As of 2016, the cremation rates in the capital area are 91.2% in Incheon Metropolitan City, 87.5% in Seoul Special City, and 87.1% in Gyeonggi-do Province, of which Incheon has the highest rate, and cremation of general corpses through the online cremation reservation service of the funeral information system is continuously increasing every year. And as of 2017, the ratio of the cremation for those outside the jurisdiction (residents of other regions) among the users of public cremation establishment in Incheon, is about 32%. As the supply capacity is expected to reach the limit within several years due to the increase in demand for such a cremation facility, I would like to suggest a policy as follows. The expansion of cremation supply capacity by increasing the number of operations in the cremation furnace; The attractions of operating funds through contracts for joint use of the cremation facility with other local governments and investment funds for the expansion of cremation facilities; The plan for controlling the demand in cremation such as an increase in cremation charge for those outside the jurisdiction(residents of other regions), should be considered.
