A pilot scale SBR (working volume, 20㎥) treating piggery wastewater was operated with real wastewater. The operation mode of intermittent feeding of raw water and sub-cycle with repeating anoxic-aeration conditions were adapted to avoid the high-strength nitrogen inhibition. In sub-cycle, aeration time for nitrification was tried to be controled with ORP and/or DO meter. The characteristics of control was somewhat different between ORP and DO. DO showed potential ability to detect complete ammonia oxidation point by the first order differential values or absolute value. Especially, DO was proved to be useful for high loading rates. ORP indicated the ending point of nitrification by the plateau appearing after bending point. Because ORP can be utilized as a diagnosis tool by its good sensitivity for the microbial condition in reactor, the simultaneous application of DO and ORP was recommended for the stable control of SBR.

Indicators of environmental conditions qualitatively and quantitatively describe the state of the environment and natural resources, and the OECD (Organization for Economic Cooperation and Development) has initiated and suggested AEIs (Agri-Environmental Indicators) to assess trends over time of the effects of agriculture on the environment and the effectiveness and efficiency of agricultural and environmental policy measures since 1990's. This study aims to develop the state indicators of water quality for agricultural water, surface and groundwater, to evaluate the environmental impacts of agricultural activities and policies by qualifying the environmental levels of a nation. Status indicators were calculated according to the agricultural water quality standards of OECD and Korea, and their trends were analyzed over time. Particularly, nitrate ($NO_3{^-}$) status indicators of ground water in 2013 were significantly lower than the ones in 2000. Overall, the water quality indicators of surface water in 2013 were higher than the ones in 2012, except for pH and DO. The groundwater quality indicators in 2013 were lower than those of previous years. The optimal management indicators were calculated to assess agricultural surface water and groundwater quality. The findings of this study indicated that the state indicators could play a significant role to establish policies and procedures for managing and conserving water resources. This study also discussed water pollution caused by agricultural and industrial effluents.

Estimating population density of Nicrophorus quadripunctatus (Coleoptera: Silphidae) in Korea

Estimating the population density of organisms is of great concern to ecologists and much effort has been put into making accurate assessment of population levels in nature. We evaluated the trapping web (TW) method for the determination of the density of species of burying beetles. We found eight and six species of burying beetles at Beopjusa and Ssanggok‐ri areas, respectively. Most of the species population comprised Nicrophorus quadripunctatus, with densities of 65 and 195 per ha for Beopjusa and Ssanggok‐ri areas, respectively. Moreover, the flight intercept trap (FIT) method from 2003 to 2007 also revealed the same trend: Beopjusa temple (2928) to Ssanggok‐ri (5835). However, the differences in number of individuals were probably due to the differences in the methods and the length of the trapping period. The populations of N. quadripunctatus exist as metapopulations, making accurate assessment of the population densities extremely difficult. We hypothesized that the TW method could accurately estimate population densities extrapolated from patch population size per area.

Purpose: We wanted to analyze the use of nutrition support for terminal cancer patients, the effect of discussing withdrawal of nutrition support and do-not- resuscitate (DNR) consent on the use of intravenous nutrition during the patient’s last week of life and at the time of death.Materials and Methods: The study involved 362 patients with terminal cancer from four teaching hospitals, and they all died between January 1 2003 and December 31 2005. The basic demographic data, the use of intravenous nutrition during the patient’s last week of life and at death, discussion of terminal nutrition withdrawal and DNR consent were evaluated.Results:In the week before death, the patients received artificial nutrition such as total parenteral nutrition (31%), intravenous albumin infusion (25%), and feeding tube placements (9%). A discussion concerning withdrawal of nutrition support was limited to 25 (7%) patients. DNR consent was obtained from 294 (81%) patients. None of the patients were directly involved in any of these decisions. The discussion about withdrawal of terminal nutrition and DNR consent with the patient’s surrogates did not have any effect on reducing the use of parenteral nutrition.Conclusion: The majority of patients dying of terminal cancer were still given potentially futile nutritional support. Modern clinical guidelines and ethical education about nutritional support at the end of life care is urgently needed in Korean medical practice to provide proper administration of terminal nutrition for end of life care.

The purpose of this research is to provide basic data suggesting the direction of disabled taekwondo player's healthy leisure activity through the analysis on actual status of disabled taekwondo players' leisure activity. The subject was 41 maleㆍfemale players participating in the 32th national athlete meet for the disabled. Data of this research was analyzed by SPSS WIN 18.0 program. For the concrete statistical method, frequency analysis and cross analysis were done so as to examine general characteristics of research subject and differences of awareness on leisure activity. To examine interests in leisure activity and differences of satisfaction, t-test and one-way Anova were conducted. And, a positive analysis was verified in significance standard p<.05, p<.01, p<.001. As a result of Scheffe method as a post-hoc test, following conclusions were obtained. First, interests in leisure activity were higher as the time of participation in contest was higher and they learned taekwondo because they want to do. For the motives of participation in leisure activity, main factors were pleasure of life, relief of stress and emotional stability. Satisfaction for leisure activity was generally more than medium level, 3 scores. What are the most necessary for leisure activity were leisure of time, money(costs), friends to enjoy together and facility/location. Obstacles of leisure activity were insufficient money(costs), insufficient time, insufficient location/facility, so they had an awareness similar to the necessary of leisure activity. Therefore, players who have lots of times to participate in taekwondo contest and learned taekwondo because they wanted to do can be the group with active tendency. And, active group showed high demands of interests and satisfaction in leisure activity. Second, costs of monthly leisure activity were increased as current grade was higher and the number of participation in contest was more. Daily taekwondo training time was longer as they were women and the number of participation in contest was more. Daily leisure time of weekdays was longer as the number of participation in contest was more. Leisure time of weekends and holidays was less than 4 hours in more than half players. For the location of leisure activity, male players preferred leisure sports center and internet cafe and female players preferred leisure sports center and shopping/department store. Especially, group with lot of times of participation in contest showed long training time, much leisure activity time and high activity costs. It means disabled taekwondo players participating in many times showed long activity time of taekwondo, but participated in various leisure activities. Third, for the form of leisure activity, they mainly preferred rest/sleeping and leisure sports. For the favorite sports as leisure activities, male players preferred soccer, basketball and swimming and female players preferred soccer, inline skating and balling. For the people they enjoy leisure activity together, there were friends, colleagues and alone in may cases. Therefore, there were various activities preferred by gender. Fourth, for the activation measures of leisure activity, there were leisure of time, facility/location and cultivation of professional instructor in order. Therefore, leisure of time was insufficient as a factor which is the most necessary for leisure activity and hinders leisure activity. So, activity program which can be approached easily around us on weekdays and holidays should be developed.
