Soil contamination in the United States is managed using a risk-based decision making process. In other words, we don't ask, 'how much soil contamination can be cleaned up\ulcorner' Instead we ask, 'how much contamination can be safely left in place\ulcorner' The determination of 'safe' levels of contamination is based upon the potential for exposure and the toxicity of the contaminants of concern in soil. Potential for exposure is determined by evaluating potential exposure pathways from source to receptor given current or reasonably anticipated land use. Soil cleanup goals are then calculated for any complete exposure pathways based upon toxicity and the route of exposure. In some cases, institutional or engineering controls are also used to limit the potential for exposure. In order to prevent a continuous degradation of environmental quality, risk-based cleanup approaches must be combined with strong contamination prevention programs. In addition, alternative risk management approaches should be incorporated into an overall risk reduction strategy.erall risk reduction strategy.

There are many Korea companies who are introducing many kinds of management renovation methods in order to attain more management achievement. So many personnels under CEO are trying to change themselves to fit those kinds of management renovation methods. Now, all kinds of books for supervisors have published, but it is not easy for those supervisors to understand those books as those books do not fit for their own companies situation. The best management methods in the best companies in U.S.A. actually can not be well introduced in Korea. So, the management methods should be changed with the environment's changing. Therefore, the company management is the process to suit the continue changing environment.

The fields of green building and ecological design have much to offer to those who are seeking to improve the ecological impact of schools and school grounds. These well established disciplines are particularly useful to existing schools considering renovations to make them more energy, water, and resource efficient as well as healthier places to work and play, Green building and ecological design principles and techniques are also very effective, of course, if incorporated into the design for brand new school buildings. The major concept of the Eco-school plan is to understand that the school consists of an ecosystem, so the design concept should focus on minimising impact but at the same time maintaining close contact with the environment. T his is becoming the basic concept in applying the Eco-school design to the new 21st century school building. This thesis is an analysis on the methods of application, based on careful examination of case-studies from the U.S.A about detailed plan element and design method, through the following six aspects ; (1) site use plan, (2) green plan, (3) water system plan, (4) materials and recycling of resources, (5) energy use plan, (6) indoor environment plan.

Disinfection process in water treatment plants (WTPs) is one of the most important step in order to inactivate waterborne disease. However, what is the necessary disinfection in WTPs was not properly established in Korea. This study was conducted to evaluate disinfection performance in nationwide water treatment plants (n=474). Disinfection requirement based on the SWTR (Surface Water Treatment Rule) of the U.S. (1-log Giardia removal) was chosen in estimating the compliance. The scope of unit process for evaluating disinfection performance includes postdisinfection process in clearwells, pipeline, and storage tank. The worst water quality condition in individual WTPs was applied for the disinfection performance evaluation. The major results are as follows. First, it was appeared that 184 WTPs (39 %) provided insufficient disinfection performance. Disinfection performance was significantly improved during past 2 years. The ratio of the number of WTPs providing insufficient disinfection performance in 1999 and 2001 was 78 % and 41 %, respectively. One of major factors for this improvement was due to the improvement of $T_{10}/T$ value in clearwell, as a result of modification of clearwell facility. Second, if disinfection criteria is 3-log Giardia inactivation at worst water quality condition, then 19 % of all WTPs can not meet this disinfection criteria. And if disinfection criteria is strengthened to 4-log Giardia inactivation, then 58 % of all WTPs can not meet this disinfection criteria. Since disinfection criteria is decided by contamination level of Giardia in source water, it also needs the investigation of Giardia occurrence in source water.

Purpose:This study aimed to identify the effect of work interruption that influenced workload and perception of patient safety culture on ward nurses. Methods: Participants were 184 ward nurses, with more than 12 months of work experience, from two tertiary hospitals in S city. A descriptive correlational study design was used. Collected data were analyzed using descriptive statistics, t-test, ANOVA, Mann-Whitney U test, Kruskal-Wallis test, Pearson's correlation, and hierarchical multiple regression analysis via SPSS version 27.0. Results: The results showed that general wards nurses had a higher degree of work interruption (t=5.632, p<.001) and workload (t=3.603, p<.001) compared to comprehensive nursing care service wards nurses. More interruption in nursing work caused more burden on work (γ=.440, p<.001) and led to lesser perception of patient safety culture (γ=- .199, p=.007). Finally, the regression analysis showed that work interruption had a statistically significant relevance on nurses' workload (F=20.582, p<.001) and perception of patient safety culture (F=8.792, p<.001). Conclusion: To alleviate ward nurses' work interruption and decrease the negative effect on workload and perception of patient safety culture, it is necessary to mediate nurse staffing level and the number of assistants and utilize the environment.
