Airway wall thickness is an important bio-marker for evaluation of pulmonary diseases such as stenosis, bronchiectasis. Nevertheless, an image-based analysis of the airway tree can provide precise and valuable airway size information, quantitative measurement of airway wall thickness in CT images involves various sources of error and uncertainty. So we have developed an accurate airway wall measurement technique for small airways with three-dimensional (3-D) approach. To illustrate performance of these techniques, we used airway phantom that consisted of 4 acryl tubes with various inner and outer diameters. Results show that evaluation of interpolation and deconvolution methods of airways in 3-D CT images, and significant improvement over the full-width-half-maximum method for measurement of not only location of the luminal and outer edge of the airway wall but airway wall thickness.

Purpose: This study aimed to evaluate the effects of a nursing education program for hyperglycemia patient care using standardized patients. Methods: This study used a nonequivalent control group pre-test and post-test non-synchronized design. A total of 50 senior university nursing students who had completed an adult nursing course participated in this study (experimental group, n=24; control group, n=26). This nursing education program was developed according to the stages of analysis, design, development, implementation, and evaluation. The collected data were analyzed using χ² -test, Fisher's exact test, independent t-test, paired t-test, and repeated measure ANOVA. Results: Significant differences were shown between the experimental and control groups in clinical performance ability (F=277.41, p<.001), communication skills (F=47.18, p<.001), self-efficacy (F=3.81, p=.031), and learning satisfaction (t=2.25, p=.033). Problem-solving ability was not statistically significant between the groups. Conclusion: The nursing education program for hyperglycemia patient care using standardized patients was effective in improving nursing students' clinical performance ability, communication skills, and learning satisfaction. Therefore, it is proposed that the education program developed in this study be used as part of an education program to enhance nursing students' abilities in caring for hyperglycemia patients.

In this study, a new consensus technique for predicting tropical cyclone (TC) intensity in the western North Pacific was developed. The most important feature of the present consensus model is to select and combine the guidance numerical models with the best performance in the previous years based on various evaluation criteria and averaging methods. Specifically, the performance of the guidance models was evaluated using both the mean absolute error and the correlation coefficient for each forecast lead time, and the number of the numerical models used for the consensus model was not fixed. In averaging multiple models, both simple and weighted methods are used. These approaches are important because that the performance of the available guidance models differs according to forecast lead time and is changing every year. In particular, this study develops both a multi-consensus model (M-CON), which constructs the best consensus models with the lowest error for each forecast lead time, and a single best consensus model (S-CON) having the lowest 72-hour cumulative mean error, through on training process. The evaluation results of the selected consensus models for the training and forecast periods reveal that the M-CON and S-CON outperform the individual best-performance guidance models. In particular, the M-CON showed the best overall performance, having advantages in the early stages of prediction. This study finally suggests that forecaster needs to use the latest evaluation results of the guidance models every year rather than rely on the well-known accuracy of models for a long time to reduce prediction error.

Sewer Rehabilitation Project (SRP) is planed, designed and constructed to perform its intended performance as sewerage delivery systems. Recently, a subject of performance evaluation methodology development for SRP has become a great deal of concern among researchers in Korea. From the view point of Sewage Treatment Plant (STP), however, the estimation of improvement efficiency for SRP is in lack of reliability due to the fact that affections for the treatment efficiency and operating condition are not reflected on SRP design and construction. In this study, statistical methodology was used in the analysis of data, which are taken during 1,186 days ($1^{st}$ Jan. 2005 - $31^{th}$ Mar. 2008) from the influent, effluent and operating conditions of full-scale STP($25,000m^3/d$). Then the effect of SRP on the influent characteristics and operating conditions changing was compared and evaluated. Results from the statistical evaluation show that SRP causes characteristic changes in influent and exerts a significant effect especially on the performance of STP.

Purpose: The aim of this project was to develop a patient safety-focused inservice education program for surgical nurse and to test the effects of this program. Methods: Methodological designs for instruments development, a pretest-posttest and a posttest design were employed. After the education, nurses' satisfaction, confidence, usefulness and application of 137 nurses were evaluated at 15 surgical units of a tertiary teaching hospital in Seoul, Korea. The education contents are 6 skill areas (infusion pump use, suction, chest tube drainage, oxygen administration, nebulizer use, insulin administration) and medication knowledge. Teaching methods were lecture, instructor demonstration, and 1:1 skill test. Descriptive statistics, Wilcoxon test, Spearman's correlation and Stepwise regression were used. Results: Satisfaction scores for skills and medication education were 4.00-4.21 (out of 5), The more performance frequency in 6 skills, the higher score in confidence as well as in usefulness and application, and the higher satisfaction with the program, the higher score in usefulness, application, confidence, and medication knowledge. Medication knowledge improved after the education (Z=-7,757, p<.001). Significant predictors of skill confidence were application of skills in job performance, medication confidence, and career in present unit. Conclusion: The results of this study suggest that systematic and continuous inservice education will improve patient safety by promoting nursing quality.
