In this study, the applicability of dynamic water quality model to TMDL system was examined, methods for setting of water quality goal and estimation of allocation loads were suggested and results of applying these methods were analyzed. HSPF model was applied for Miho stream basin as a dynamic water quality model. The model was calibrated using measurement data obtained in 2009~2010 and showed satisfactory performance in predicting daily variations of flow rate and BOD concentration. Methods for TMDL application were categorized into 3 cases; water quality management (1) considering low flow condition(Case I), (2) considering entire period of the year (Case II) and (3) considering the worst water quality condition (Case III). BOD water quality goals at the end of Miho stream watershed increased in the order of Case IICase I>Case III. If further researches on base precipitation and method for model input of nonpoint source pollutant were carried out, water quality could be managed more reasonably and scientifically by applying dynamic water quality model to TMDL. The result of this study is expected to be used as primary data for TMDL using dynamic water quality model.

To detect individual vehicular speed, double loop detection technique has been widely used. This paper investigates four methodologies to measure individual speed using only a single loop sensor in a traveling lane. Two methods developed earlier include estimating the speed by means of (Case 1) the slop of inductance wave form generated by the sensor and (Case 2) the average vehicle lengths. Two other methods are newly developed through this study, which are estimations by measuring (Case 3) the mean of wheelbases using the sensor installed traversal to the traveling lane and (Case 4) the mean of wheel tracks by the sensor installed diagonally to the traveling lane. These four methodologies were field-tested and their accuracy of speed output was compared statistically. This study used Equality Coefficient and Mean Absolute Percentage Error for the assessment. It was found that the method (Case 1) was best accurate, followed by method (Case 4), (Case 2), and (Case 3).

Purpose: This study was done to develop a realistic clinical case and investigate nurses' decision-making about nurses' ethical dilemmas with physicians in the fields of nursing practice. Methods: Case development and a hypothetical case study were used. Participants were 52 nurses. Data were collected in 2012 and 2013 using an open-ended questionnaire and interviews and analyzed using content analysis and descriptive statistics. Results: Various dilemma situations between nurses and physicians, such as violence, deathbed, medication prescription, and physicians' incapacity unfairness, were suggested. A clinical dilemma case about medication prescription was developed based on nurses' experiences. Nurses' responses to the developed case situation and responses were classified into five types. Various reasons were given for making the decisions and about 56% of the nurses decided to notify their supervisor without deleting nursing records. Conclusion: In this study, a realistic clinical dilemma case was developed, and nurses' ethical decision making was identified. These findings can be used in developing effective strategies for nurses to solve ethical dilemmas and to improve ethical decision-making abilities.

Purpose: The purpose of this study was to evaluate the effectiveness of case management for patients with hypertension on their health status and medical service utilization. Methods: This study was a secondary analysis of data collected for a larger study of chronic disease management in 2008 using the National Health Insurance Corporation database. A total of 12,944 patients who received case management for hypertension were included in this analysis. The subjects of case management were classified into subgroups, namely, over-use, under-use, and non-use groups according to the amount of medical service utilization. To compare the medical service utilization, a control group was selected randomly. The data were analyzed through descriptive statistics, McNemar test, and ANOVA. Results: All the subgroups displayed significant differences in blood pressure, self-management, social support, and their characteristics of medical service utilization. The total medical expense of the under-use and non-use groups increased after case management. However, there was no decrease in the medical expense of the over-use group. Conclusion: This finding suggests that there is a need to re-examine why patients overuse medical services and to supplement specific strategies for encouraging appropriate medical service utilization, and enhancing case management efforts for the over-use group.

Today, the public assistance program in Korea is provided mainly for the livelihood protection beneficiary in urban area. The fact that the urban community-centered program is also applied to the livelihood protection beneficiary in rural area brings about some problems in fitness and effectiveness of resource distribution. The purpose of my study is to present my opinion that the public assistance program for the rural community should be put in practice after being fully distinguished from the urban program for the effective distribution of limited social welfare resources to insure the minimum standard of living and seek the self-support contribution which is the purpose of the public assistance program. The subject for this study were livelihood protection beneficiaries living in both rural and urban area. And the study was carried out in this parts: first, the way of life in them, second, the contents of 6 main public assistance programs being carried out. Total number of the livelihood protection beneficiaries are 279 case: 143 case from 15 Dong in 5 cities, and 136 case from 15 Myun in 5 counties. And the social worker who are performing the public assistance programare consisted of 50 case: 25 case from 5 Dong in 5 cities, and 25 case from 5 Myun in 5 counties. This research reach the result that the differentiate performance of the public assistance program in rural community would be an effective device for self-support to be freed from the vicious circle of poverty.

Psychiatric nursing is a specialty where nursing students experience many difficulties in applying what they have learned in theory to clinical practice. Therefore, a situation-oriented case-based strategy is required to help them overcome the limitations of psychiatric nursing clinical practice and reduce their burden. This study aimed to measure the effectiveness of a psychiatric nursing clinical practice program using situation-oriented case-based learning. Participants comprised 63 nursing students in psychiatric nursing classes. The students were asked to create a scenario of interaction between a nurse and patient based on a case study. Empathy, therapeutic communication ability, and attitudes toward mental illnesses were measured. We analyzed the effectiveness of the program by comparing changes in the nursing students' empathy, therapeutic communication ability, and attitude toward mental illness after the program. The participants showed significant increases in empathy and therapeutic communication abilities. However, there were no significant changes in attitudes toward mental illnesses. Based on the results of this study, it is expected that situation-based learning will be effective for students who have difficulties in certain aspects, such as COVID-19, or where there are limited clinical practice opportunities, such as psychiatric nursing.
