Improvement of the classification accuracy is one of the major concerns in the field of remote sensing application research in recent years. Previous research shows that the accuracy of the conventional classification methods based only on the original spectral information were usually unsatisfied and need to be refined by manual edit. This present paper describes a method of combining the image processing, ancillary data (such as digital elevation model) and expert knowledge (especially the knowledge of local professionals) to improve the efficiency and accuracy of the satellite image classification in hilly land. Firstly, the Landsat TM data were geo-referenced. Secondly, the individual bands of the image were intensitynormalized and the normalized difference vegetation index (NDVI) image was also generated. Thirdly, a set of sample pixels (collected from field survey) were utilized to discover their corresponding DN (digital number) ranges in the NDVI image, and to explore the relationships between land use type and its corresponding spectral features . Then, using the knowledge discovered from previous steps as well as knowledge from local professionals, with the support of GIS technology and the ancillary data, a set of conditional statements were applied to perform the TM imagery classification. The results showed that the integration of image processing and spatial analysis functions in GIS improved the overall classification result if compared with the conventional methods.

In terms of deregulation requests from business, incidents at construction sites are rapidly increasing after reducing the regular safety training hours. Especially, to prevent incidents through safety trainings for construction site workers, who have lots of hazardous tasks than general manufacturing, is not only to protect property of both the companies and the country but also to increase their profits. That is why there are loud voices regarding that the safety training is a core mandatory to prevent industrial incidents. But, most companies, as soon as the deregulation for safety training is implemented, mitigated conducting safety trainings to prevent incidents. With this, the incidents are currently to be increased and caught in a vicious circle of many incidents at the smaller companies because of their absentmindedness regarding safety training due to their poorness as subcontractors of major companies, comparing to major companies. This study explains that the difference between managers and workers are existing about safety awareness and knowledge. And, we confirmed that the educational factor led by deficiency of safety awareness and knowledge was the major factor.

Purpose: This study was performed to investigate the level of knowledge, self-confidence, and intention of basic life support (BLS) and identify the reason why clinical nurses lack confidence to initiate BLS at the cardiac arrest scene. Method: A cross-sectional survey was used with questionnaires which authors developed; a BLS knowledge questionnaire and a tool for measuring the level of self-confidence and intention of performing BLS. The subjects consisted of 396 nurses by convenient sampling from ten small to medium sized hospitals in Korea. Data were collected from March to August, 2008. Data were analyzed by the SPSS/WIN 14.0 program with t-test, ANOVA, and Pearson correlation coefficients. Results: The percentile score of BLS knowledge was 40.6%, self-confidence 62.1%, and intention 73.0%. Clinical career rather than BLS knowledge has a significant effect on increasing the self-confidence and intention of performing BLS. A major reason for not performing BLS was lack of confidence in operating an AED (automatic external defibrillator). Conclusion: An effective and continuous training program especially including AED for CPR should be provided with clinical nurses to increase self-confidence and intention of performing BLS and to improve the survival of cardiac arrest patients in the hospital.

Purpose: The aim of this research was to determine knowledge and management of tracheal tube cuffs among nurses of ICU. Methods: This descriptive survey recruited 150 nurses working at 8 different adult ICUs within 2 tertiary hospitals in Seoul. A survey questionnaire was developed to measure cuff management. The internal reliability of the tool was examined by Cronbach's ${\alpha}$. Descriptive statistics and multiple regressions were used to analyze data. Results: Among the 150 nurses, 94.0% replied that they would measure the pressure themselves. With regard to nurses' knowledge about tracheal tube cuffs, only 6% answered that they knew 'the appropriate cuff pressure'. The existence of a measuring device (p < .001), a guideline (p < .001), the level of knowledge on its related complications(p = .003), and clinical experience (p < .001) together accounted for 35.0% of the total variation in cuff management. They pointed out that the lack of time and the lack of education were major barriers to appropriate management; whereas education update was the most imperative factor for good management. Conclusion: ICU nurses have inappropriate knowledge and practice in cuff management. Therefore continuing education is necessary for better practice of tracheal tube cuff management.
