We studied the association of nonspecific bronchial hyperresponsiveness with general characteristics, exposure concentration, respiratory symptoms, chest x-ray findings, past histories and pulmonary function. We determined bronchial hyperresponsiveness by methacholine challenge test. And we conducted a respiratory symptom questionnaire and performed spirometry on 111 workers occupationally exposed to isocyanates in various industries. About 21.6% of subjects had bronchial hyperresponsiveness. No significant differences were observed between the hyperresponsive and non-responsive group with respect to age, sex, employment period, height, and smoking histories. Cough and breathlessness were significantly associated with the bronchial hyperresponsiveness. The hyperresponsive group had more experience of bronchitis and asthma in the past than the non-responsive group. The lower $FEV_1\;and\;FEV_1%$ were closely related with bronchial hyperresponsiveness. Bronchial hyperresponsiveness seems to be associated with some of respiratory symptoms, past histories and pulmonary function parameters in workers exposed to isocyanates.

AnnAGNPS model was applied to a catchment mainly occupied with bushland for modeling non-point source pollution. Since the single event model cannot handle events longer than 24 hours duration, the event-based calibration was carried out using the continuous mode. As event flows affect sediment and nutrient generation and transport, the calibration of the model was performed in three steps: Hydrologic, Sediment and Nutrient calibrations. The results from hydrologic calibration for the catchment indicate a good prediction of the model with average ARE(Absolute Relative Error) of $24.6\%$ fur the runoff volume and $12\%$ for the peak flow. For the sediment calibration, the average ARE was $198.8\%$ indicating acceptable model performance for the sediment prediction. The predicted TN(Total Nitrogen) and TP(Total Phosphorus) were also found to be acceptable as the average ARE for TN and TP were $175.5\%\;and\;126.5\%$, respectively. The AnnAGNPS model was therefore approved to be appropriate to model non-point source pollution in bushland catchments. In general, the model was likely to result in underestimation for the larger events and overestimation fur the smaller events for the water quality predictions. It was also observed that the large errors in the hydrologic prediction also produced high errors in sediment and nutrient prediction. This was probably due to error propagation in which the error in the hydrologic prediction influenced the generation of error in the water quality prediction. Accurate hydrologic calibration should be hence obtained for a reliable water quality prediction.

The purpose of this study is to observe the influence education experience (home, school, and mass media) on reducing practice behavior(purchasing, using, disposing and leading) of food-related wastes. The study also sought to promote strategy and suggest effective activation plans for the vitalization of behavior of reducing food-related wastes. The study subjects were 412 adult consumers who answered a structured questionnaire. The main findings are as follows: First, the scores of home education experience were 3.61±0.71, which was the highest, and 3.45±0.74 for school education experience, which was the lowest. Second, according to factor analysis, the reducing practice behavior of food-related wastes was converged purchasing, using, disposing and leading behavior. The scores of disposing behavior were 3.79±0.67, which was the highest, and 2.87±0.82 for leading behavior, which was the lowest. Third, the common variables influencing the reducing practice behavior(purchasing, using, disposing and leading) of food-related wastes were home education and mass media and the powerful variable influencing was home education. The results of this study can be used as basic data for the development of educational programs for effective food-related waste reduction.

This study investigated the effects of NPS(non point source) pollution reduction of sediment traps through field experiments. Various sizes of 4 sediment traps were applied in a upland field located in Gunwi and assessed the infiltration and storage effects as well as NPS pollution reduction effects of this technique. The characteristics of deposited soil in the sediment traps were also analyzed including distribution of particle size, soil texture, and chemical properties. The results showed that slightly different composition of soil particle size from each sediment trap with high proportion of 0.15mm and 0.25mm ranges of soil particle diameters, while the loamy sand is the main types of deposited soils in the sediment traps. Decreased NPS pollution were observed from the water quality analysis of the samples taken from the sediment traps. Further research need to be proceeded continuously to improve this technique in order to utilize on upland fields for management of agricultural NPS pollutions.

Saemangeum development project is the world's largest tidal flat reclamation project. It is currently under construction, and proceeding with phased developments. The construction of agricultural areas within the Saemangeum reclamed lands is also a part of this project. These areas will have multi-functional complexes aiming to produce mainly eco-friendly horticultural crops and livestock products for the purpose of export. The major concern is to obtain sufficient water with appropriate quality to supply to those areas. The objective of this study is therefore to provide available water supply plans for agricultural purpose, especially for horticulture and livestock complexes. Alternative methods for water supply are purifying water from the Saemangenm lake or using water supply services providing by K-water or local governments. This study investigates to find an economical water supply plan through comparisons of these methods. As a result, the water purification method with Saemangeum lake water could be advantageous for given water supply conditions to horticulture and livestock complexes.

Based on the results of the study on how social tourism information platform affects customers’ e-loyalty and continued use, this study aims to provide practical as well as academic implications so that various customer-tailored strategies can be implemented in the future operation of social tourism information platform in the travel industry. An empirical analysis was conducted through a survey to identify the causal relationship between the social tourism information platform, e-faithfulness and continued use of the travel agency’s social tourism information platform, and the following results were derived. First, the hypothesis that interaction and information reliability, a sub-factor of a travel agency’s social tourism information platform, would have a significant positive influence on e-faith was supported, but the hypothesis that usefulness would have a significant positive effect on e-faith was not supported. Second, the assumption that complementarity, reliability and usefulness, all of the subcomponents of the social tourism information platform, will have a significant positive impact on the continued use, was not supported. Third, the hypothesis was adopted that e-fidelity would have a significant positive influence on the continued use.

Purpose: This study was to develop and evaluate the clinical utility of a nursing educational program to reduce the cancer worry of colorectal cancer patients’ family members (RCW-FM) in Korea. Methods: The RCW-FM was developed based on several preliminary studies: an ethnographic and two quantitative studies to understand the educational needs among Korean colorectal cancer patients and their families. A one week clinical genetic educational course for clinical cancer nurses was implemented, and the RCW-FM led by cancer genetic nurses was constructed. A one group pretest-posttest design was implicated to evaluate the change of the family members’ knowledge about colorectal cancer (KCR) and the level of the reduction of cancer worry (CWR). Results: The mean score for KCR significantly increased from 11.75±1.28 to 13.87±1.13 (p<.05). The mean score of CWR was 4.25±.89. Conclusion: This new RCW-FM is a satisfactory educational program for reducing the cancer worry of the colorectal patients’ family members. But it needs to provide more practical, specific information including a long term perspective, tailored specifically for what Korean families want to know. It should also incorporate the preventive guidelines recommended for high risk hereditary or familial colorectal cancer.
