Four major river basin in Korea has been managed with Total Maximum Daily Load(TMDL) System. Water quality indicators as targeted pollutants for TMDL were BOD and TP. In order to satisfy water quality criteria, government allocation using public treatment facilities and its action plan has been used. However, the role to improve water quality were recently faced to its limitation. It is time to require the role of non-government allocation in private discharge facilities to control good water quality. This study investigated three different scenarios in reduction demands of non-government allocations about industry and private sewages. The three different scenarios were discharge under 1) legal water quality standard, 2) water quality level in 2011 and 3) current water quality level with maximum value in group. The results showed that reduction potential in water discharge for TP indicator was 1,118kg/day, under second scenario with 20% of deduction. This results arrived at 42% of whole reduction potential costs and 0.012mg/L improvement in water quality. In conclusion, to intrigue voluntary participation in non-government allocation, various benefits such as tax reduction, tax exemption, and water quality trading should be provided.

It is one of the most critical steps identifying impaired waterbodies exactly in the selection of target water quality indicators for the management of Total Maximum Daily Loads (TMDLs). Excess ratio and excess level were applied and analyzed by the stream zone basis in order to evaluate water impairment for Nakdong, Geum, Youngsan and Seomjin rivers. Each river basin was divided into stream zones in the light of its watershed and waterbody characteristics. Selected water quality parameters discussed in this study were pH, DO, BOD, COD, SS, T-P, T-Coli and F-Coli. The excess ratios of the water quality parameters were used to discriminate water bodies that did not meet water quality standards. The excess levels were used to classify the degradation of water quality. The excess ratios and the excess levels to the water quality criteria of the medium influence areas were used for each stream zone. The results indicate that the excess ratios and the excess levels are varied on the stream zone in each river basin. Three parameters, pH, DO and SS, met water quality standards in all stream zones. The other five parameters indicated very high excess ratios in most waterbodies, and especially T-P and T-Coli revealed to be very high excess levels in some waterbodies. These parameters could be considered as major target indicators for the management of TMDLs.
This study is a qualitative analysis that conducted a focus group interview to analyze the experiences of daily life of the elderly living alone and their chronic diseases management, and to explore the meaning, nature, and difficulties associated with. The subjects of this study were elder who lives alone without cognitive impairment and over 65-year-old. There were total 31 people and divided into 5 groups and they had 60 minutes interview. By this study, there were four themes of 'difficulties of daily life', 'suffering from chronic diseases', 'fear of the future', 'acceptance of life'. In conclusion, the elderly living alone felt difficulty in daily life due to physical aging and chronic illnesses, and they felt that they were accepting life at the same time while feeling the fear of the future situation. Therefore, in order to improve the life satisfaction and life quality of elderly people living alone, it is necessary to provide institutional devices that enable daily life such as meals and laundry to be maintained and to develop of an intervention program in order to maintain physical health. In addition, an intervention program should be developed to reduce the fear of future uncertainty and positively accommodate the life.
The purpose of this research was to identify nursing interventions performed by MICU and SICU nurses. For data collection this study used the taxonomy of the Nursing Interventions Classification (NIC : 433 nursing interventions) which was modified by McCloskey and Bulecheck(1996). Each of the 433 interventions were identified as used by MICU and SICU nurses. More than 50% of the ICU nurses performed 280 nursing interventions at least monthly. Rarely used interventions included 26 nursing interventions in the childbearing care class. Overall, both MICU and SICU nurses used interventions in the Physiological : Complex domain most often on a daily basis and the interventions in the Family domain least often. The most frequently reported interventions as being used daily in the MICU were chest physiotherapy, airway suctioning and coughing enhancement and, in the SICU, documentation and airway suctioning. There were significant differences between MICU and SICU nurses in 17 nursing interventions childbearing care, cognitive therapy, communication enhancement, coping assistance, elimination management, lifespan care, health system mediation, immobility management, medication management, neurologic management, patient education, psychological comfort promotion, physical comfort promotion, respiratory management, risk management and information management. The SICU nurses performed there interventions more frequently than the MICU nurses. These findings will help in building of a standardized language for the MICU and SICU and enhance the quality of nursing care.
Objective : This study aimed to determine the impact of an instrumental daily living activity program for adults with developmental disabilities on their daily living activities and quality of life (QOL). Methods : This study used a single-group pre-test-post-test experimental design. Participants comprised 17 adults with developmental disabilities from the Welfare Center for the Disabled. This program consisted of 10 sessions, including pre- and post-assessments, pertaining to training and education on grocery shopping, meal preparation and cleaning, home management, safety, and emergency management. The evaluation tools used in this study were the Quality of Life Questionnaire, Korean version of the Life Space Assessment (K-LSA), and Korean version of the Instrumental Activities of Daily Living (K-IADL). Results : There was a statistically significant difference in the QOL and K-IADL scores before and after the instrumental activities of daily living occupational therapy program, and there was no statistically significant difference in the K-LSA scores. Conclusion : This study confirmed that implementing an IADL program for adults with developmental disabilities had a positive impact on performance and QOL. For adults with developmental disabilities to participate in daily life and society, interventions for work participation, including training in activities of daily living, must be expanded.

Soil erosion is an natural phenomenon. However accelerated soil erosion has caused many environmental problems. To reduce soil loss from a watershed, many management practices have been proposed worldwide. To develop proper and efficient soil erosion best management practices, soil erosion rates should be estimated spatially and temporarily. The Universal Soil Loss Equation (USLE) and USLE-based soil erosion and sediment modelling systems have been developed and tested in many countries. The Sediment Assessment Tool for Effective Erosion Control (SATEEC) system has been developed and enhanced to provide ease-of-use interface to the USLE users. However many researchers and decision makers have requested to enhance the SATEEC system for simulation of soil erosion and sediment reflecting effects of single storm event. Thus, the SATEEC R factors were estimated based on 5 day antecedent rainfall data. The SATEEC 2.1 daily R factor was applied to the study watershed and it was found that the R2 and EI values (0.776 and 0.776 for calibration and 0.927 and 0.911 for validation) with the daily R were greater than those (0.721 and 0.720 for calibration and 0.906 and 0.881 for validation) with monthly R, which was available in the SATEEC 2.0 system. As shown in this study, the SATEEC with daily R can be used to estimate soil erosion and sediment yield at a watershed scale with higher accuracy. Thus the SATEEC with daily R can be efficiently used to develop site-specific soil erosion best management practices based on spatial and temporal analysis of soil erosion and sediment yield at a daily-time step, which was not possible with USLE-based soil erosion modeling system.
Taipei Water Management Office (TWMO) is one of the eleven district offices in Water Resource Agency. Water management is the top priority to be pursued both on daily management and long-term management at TWMO. There are five departments to perform a wide range of tasks in addition to water management. All management prescriptions are simply to provide sustainable clean water for about four millions population in Taipei. TWMO has gone through 16 years experience of development and implementation of GIS in water management. The objectives of this paper are to provide the major ingredients of successful and operational GIS for water management. The five departments at TWMO have performed tasks such as city planning, construction management, forest management, land use enforcement, soil and water conservation, water quality monitoring and protection, garbage collection, and sewage disposal management. Data base creation was one of the major jobs to be done. Update of data base has to be done on a daily basis. Computers, its peripheral, and software are essential for GIS developed at TWMO. Know-how and technical skill on computers and GIS for every technician are contributing significantly such that GIS can be implemented on most of jobs performed at TWMO. Implementations of GIS have been pursued by application modules on a task-oriented basis. Application modules are simple, easy to use, and menu driven with only Chinese. Web-based and mobile GIS are the new components that make water management at TWMO stay on the right course. To solve problems encountered in water management by GIS at TWMO can be easily and user-friendly may be the most important experience.

Purpose: This study was conducted to understand the effects of daily hassle stress on the psycho-social health of male workers in manufacturing industry. Methods: Daily hassle stress and psycho-social health in manufacturing industry workers were estimated by using the Daily Hassles Scale for Korea Workers (DHS-KW) and general health questionnaire (GHQ), respectively. Results: The subjects were 553 male workers who had never been occupationally exposed to hazardous chemicals, were mean age 39.6 years and mean work duration was 15.66 years. DHS-KW total mean score had significantly higher in young ages (twenties and thirties ages), office workers, managers and daytime workers than other groups. GHQ total mean scores were significantly higher in un-married, daytime and overtime workers than others. DHS-KW and GHQ score correlated that they were negative correlation with age and working years, but was positive correlation with working hours and overtime work. The significant correlation between DHS-KW and GHQ were observed almost variables of DHS-KW and GHQ except a domestic and daily problem in DHS-KW variables. Domestic and daily problems were only significantly correlated with anxiety and insomnia of GHQ variables. Conclusion: This study indicated that physical health was associated with work condition and psychsocial health was mainly associated with domestic and daily problems of DHS-KW variables. Thus, the study on Daily Hassles stress and related with work stress should be further investigated for the comprehensive health program including stress management and coping behavior.

To control organic matters, it needs to manage not only biodegradable organic matters but also refractory organic matters. Refractory organic matters from municipal wastewater, industrial wastewater, non-point sources and etc., have been continuously discharged to the near watersheds. It is estimated that the refractory organic matter ratios are continuously increased in waterbody. In watersheds of the Total Maximum Daily Loads (TMDLs), it was investigated that COD/BOD ratios increased in many unit watersheds of the 4 major river basins. The portions COD/BOD ratios increased were found to be a 97% of Geum River unit watersheds, a 81% of Yeongsan/Seumjin River unit watersheds, a 78% of Nakdong River unit watersheds, a 70% of Han River unit watersheds, respectively. Therefore, it has become important for establishment of effective management strategies to control refractory organic matter in watersheds of the Total Maximum Daily Loads (TMDLs). In order to properly manage organic matters including refractory organic matters, the present organic indicator (BOD) has to be converted to TOC (or COD). Compared to COD and BOD, TOC, as a organic matter indicator, is evaluated more appropriate.
