The policy of total maximum daily load (TMDL) was introduced to manage wasteload within the loading capacity to achieve water quality standards in the watershed. While the TMDL was implemented, the institutional and technical correction for the improvement of procedure was accomplished even though there were various problems and basically through the process of trial & error. However, a fundamental improvement of this policy is needed to implement the TMDL. This study has come up with a new viewpoint on improving this procedure for reasonable implementation of TMDL. First of all, the water quality and flowrate monitoring of the tributaries should be implemented. This should be done through the establishment of a monitoring system which will include standards of scope, a set time period, water quality parameters and frequency follow ups for the implementation of TMDL. The basic plan in all of the watersheds should be developed based on the establishment of water quality parameters and standards for water use and ecological purposes according to the results of the water quality and flowrate monitoring in the watersheds. The implementation plan for water quality improvement should be established in the watersheds where exceeds the targeted water quality standards. The performance assessment of TMDL should be conducted every year to meet the satisfaction assessment of water quality standards in the watersheds. Finally, if the water quality standards in the watersheds can not be attained or the water quality parameters and standards should be changed, the implementation procedure will be performed according to the iterative process. On the contrary, the policy of TMDL in the watersheds where the water quality standards have been met the goal will be finished.

Even though the center of Cheongju city needs redevelopment because of a doughnut phenomenon, it has to be permitted within the environmental carrying capacity like a target water quality proposed on the Total maximum daily loads(TMDL) of Musim and Miho river watersheds. The aim of in this study is to identify the limit of redeveloping Cheongju downtown after analyzing its environmental carrying capacity using QUAL2E model. As a result of modeling various scenarios, the water quality of Musin river was shown that $BOD_5$ is 2.3mg/L which is the target water quality in the double of existing development plan of the Cheongju downtown. The water quality of Miho river was $BOD_5$ 3.97mg/L which is less than the target water quality of Miho B watershed in the same condition. Therefore, this means that the limit of redevelopment within the environmental carrying capacity of cheongju downtown was estimated to be the double of existing development plan.

Purpose: This study aims to analyze general types of R&D Quality Assurance(R&D QA) and to identify key quality elements for R&D QA. R&D QA is defined as all the planned and systematic actions to verify whether R&D processes are conducted in a proper manner and the results of R&D fully satisfy customers' requirements. Methods: The existing R&D QA guidelines and the some cases were reviewed. From the review, three general types are analyzed and thirteen key quality elements are identified. Then, the survey on the eighteen domestic experts has been conducted for prioritization of the identified elements. Results: As the result of this study, three types for R&D QA based on quality elements, standard process, and final evaluation are analyzed. Related to the first type, thirteen quality elements, e.g., administrative plan, project plan, process management and so on, are identified and prioritized. Conclusion: This study contributes to develop the baseline for R&D QA including the types and the key quality elements. It may be helpful for the institute that has an interest adopting R&D QA.

In the Seoul Metropolitan Area(SMA) photochemical air pollutants, nitrogenic compound and particulate matters have increased substantially due to mobile sources, power plants and so on. Therefore 'Special Act on Seoul Metropolitan Air Quality Improvement' was enacted on 2003 in order to improve air quality in the SMA. According to the Special Act, Central and local government have developed the state implementation plan(SIP) to reduce air pollutant emissions from various local sources. One of the key elements of the SIP development is the air quality modeling since modeling results can be used to establish emissions control strategies as well as to demonstrate attainment of air quality goals for ozone, particulate matter, and so on. Air quality modeling, therefore, can be usefully utilized to investigate the effects of government's efforts according to control strategies or measures. Using the air quality model, we can determine whether the implementation plan should be revised or not. A number of questions, however, has been raised concerning accuracy, consistency and transparency of modeling results because if we do not trust modeling results, all the measures dependent on modeling becomes in vain. So, without dealing with these questions, we can not guarantee the reliability and utilizability of air quality modeling results. In this study, we tried to establish standard methodology for air quality modeling in order to ensure consistency and transparency of modeling results used in the development and evaluation of national air policy. For this purpose, we established air quality modeling guideline to provide or recommend modeling procedures, vertical and horizontal domains, input data of meteorological and air quality modeling and so on.

It is necessary to evaluate performances hitherto carried out in the management of Total Maximum Daily Loads (TMDLs) and to set up direction so that this system can be improved continuously in the future. This study was investigated load allocation achievement ratio, water quality goal achievement ratio and interrelation between water quality goal and load allocation for the first period (2004~2010). Load allocation achievement and BOD water quality goal achievement ratio were 50% and 73% in Guem River Basin, respectively. The main reason for excess of load allocation and shortfall of water quality goal were unfulfilled reduction plan and pollution sources increment. Therefore, it is necessary to develop enhanced pollution sources prediction method and make a list realizable reduction plan. 63% of the unit watershed was not interrelation between water quality goal and load allocation. The reason why water quality goal and load allocation had not correlation were water quality of upper unit watershed, increment of inflow quantity, effluent water quality of wastewater treatment plant affected the unit watershed, increment of inner productivity by algae, water quality deterioration during the specific period, river management flow, etc.

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.
