Objectives : The purposes of this study were to investigate the recognition of Mibyeong, symptom, management plan and correlation between quality of life and health condition, and to suggest a plan for managing Mibyeong status. Methods : Participants were recruited based on the same sampling methods used on the previous study performed in 2013 based on area, gender and age. Questionnaires were collected by Gallup Korea professional surveyor through face-to-face interviews. The questionnaires contain questions about the recognition of Mibyeong, symptom, management plan and the quality of life in accordance with the relevant health conditions. Descriptive statistics were used for data analysis and the results were expressed as percentage ratios (%). Results : 1,100 of people were acquired in 2015. The responses for "First time to hear of Mibyeong" have shown that the percentage were reduced from 80% to 67% compared with 2013 data. The ratio of Mibyeong's symptoms in 2015 were similar to 2013. we suggested some ways to deal with the Mibyeong status including behavior adjustment (non smoking, non alcohol, control sleep pattern), herbal tea, health functional food, exercise, preventive health care (qi-gong, yoga), meditation, home health care medical device (hot-pack, seat device for fumigation, massager), and medical service (hospital, medical clinic oriental medical clinic). Almost people showed that positive opinion with them. There were significant correlation between quality of life with the health status rather than Mibyeong or disease group. Conclusions : This study was performed through scientific questionnaires collected in 2013 and 2015 to investigate people's understanding of Mibyeong as a present condition in Korean public. Some questions had significantly different responds between both years while others showed similar trends for both years. These results suggest that the concept of Mibyeong in oriental medicine could provide a management mechanisms that help people to manage the Mibyeong status.

The water balance analysis for the long-term water resources plan is a simple calculation that compares water demands with possible water supplies. For a watershed being considered the reports on the performance of the water balance analysis, however, have shown inconsistent results and thus have not earned credibility due to the uncertainty of the data acquired and models used. In this research, uncertainties in the water scarcity estimate were assessed through probability representation based on the Monte Carlo simulation using Latin Hypercube Sampling (LHS). The natural flow, municipal demand, industrial demand, agricultural demand, and return flow rate were selected as representative input variables for the water balance analysis, and their distributions were set based on the linear regression and the entropy theory. The statistical properties of the output variable samples were analyzed in comparison with a deterministic estimate of the water scarcity of an existing study. Application of LHS to three sub-basins of the Geum river basin showed the deterministic estimate could be overestimated or underestimated. The sensitivity analysis as well as the uncertainty analysis found that the return flow rate of the agricultural water is the most uncertain but is rarely sensitive to the output of the water balance analysis.

Animal disease surveillance system, defined as the continuous investigation of a given population to detect the occurrence of disease or infection for control purposes, has been key roles to assess the health status of an animal population and, more recently, in international trade of animal and animal products with regard to risk assessment. Especially, for a system aiming to determine whether or not a disease is present in a population sensitivity of the system should be maintained high enough not to miss an infected animal. Therefore, when planning the implementation of surveillance system a number of factors that affecting surveillance sensitivity should be taken into account. Of these parameters sample size is of important, and different approaches are used to calculate sample size, usually depending on the objective of surveillance systems. The purpose of this study was to evaluate the sensitivity of the current national serological surveillance programs for four selected bovine diseases assuming a specified sampling plan, to examine factors affecting the probability of detection, and to provide sample sizes required for achieving surveillance goal of detecting at least an infection in a given population. Our results showed that, for example, detecting low level of prevalence (0.2% for bovine tuberculosis) requires selection of all animals per typical Korean cattle farm (n = 17), and thus risk-based target surveillance for high risk groups can be an alternative strategy to increase sensitivity while not increasing overall sampling efforts. The minimum sample size required for detecting at least one positive animal was sharply increased as the disease prevalence is low. More importantly, high reliability of prevalence estimation was expected with increased sampling fraction even when zero-infected animal was identified. The effect of sample size is also discussed in terms of the maximum prevalence when zero-infected animals were identified and on the probability of failure to detect an infection. We suggest that for many serological surveillance systems, diagnostic performance of the testing method, sample size, prevalence, population size, and statistical confidence need to be considered to correctly interpret results of the system.

The Purpose of this study is to suggest the necessity of linking and coordinating Cultural Tourism Festivals among local governments and to propose a plan for maximizing the effects of these festivals. The 'World Ceramic Exposition 2001 Korea' which took place from August 10th to October 28th was selected as a case study for the linkage plan of Cultural Tourism Festivals among local governments. Data were collected from a random sampling of visitors to 'World Ceramic Exposition 2001 Korea' from 24 to 28 October, 2001. 369 samples from a total 375 respondents were used for the final analysis. The contents of the questionnaire consisted of the cognition and satisfaction about the effects of the festival linkage among local governments and the preference of festival linkage types. The results of the analysis showed that not only festival staff but also visitors recognized the necessity of linking festivals among regions. Both visitors and festival staff had a positive attitude about the effects of the linked festival. In addition, they highly rated the 'World Ceramic Exposition 2001 Korea' as a successful festival. Visitors were satisfied with the festival. Furthermore, the number of visitors was more than staff expected. The organizing committee and staff considered the 'World Ceramic Exposition 2001 Korea' as a successful festival. The successful evaluation of the 'World Ceramic Exposition 2001 Korea' was related to the successful linkage of the festival. This study originated in the increased necessity of linking cultural Tourism Festivals among local governments. Since it is a transcendental study, it is not only significant but also limited. However, in the near future, more varied case studies about the linkages of Festivals will be conducted and these will generalize the results of this study and test the effectiveness of the linkage plans through positive analysis. For the effective linking of festivals among regions, it is necessary to study the definition of factors that affect visitors satisfaction, and determine which methods will improve visitors satisfaction.
