Purpose: This study investigated the effectiveness of simulation training with a hybrid model of student nurses' performance ability and reported self confidence. Methods: A nonequivalent control group with pre-posttest was designed. Data collection was done during the first semester in 2012 at a college of nursing in Seoul. Nursing performance ability and reported self confidence related to taking care of patients with urinary problems were evaluated. The treatment group (n=96) received simulation training of a catheterization procedure with a hybrid model involving standardized patients and a mannequin. Nursing students in the comparison group (n=84) did not receive the simulation training but would receive it prior to their next clinical practicum's. Results: The treatment group showed a significantly higher performance ability and reported self confidence than that of the comparison group. The perceived helpfulness and contentment of the simulation training in experimental group was high. Conclusion: The findings of this study demonstrated that simulation with a hybrid model was effective in teaching skills prior to the clinical experience which suggests that skill development is not dependent on the actual clinical situation. Nurse educators should consider simulation training as a tool beyond that of clinical practicum.

Purpose: This study was conducted to test the impact of simulation-based education program for emergency airway management on self-efficacy and clinical performance ability. Methods: A quasi-experimental non-equivalent control group pre-post test design was used. A total of 60 nurses, 30 nurses assigned to the simulation-based education group and 30 nurses to a traditional lecture group. The treatment group received a lecture, small group workshop and team simulation whereas the comparison group received lectures. Results: The participants in the simulation-based education group reported significantly higher self-efficacy of emergency airway management compared to participants in the lecture only group (t=5.985, p<.001). The simulation-based education group showed significantly higher clinical performance ability of emergency airway management compared with the lecture group (t=5.532, p<.001). Conclusion: Simulation-based education was verified to be an effective teaching method to improve the self-efficacy, clinical performance skills of nurses in the learning of emergency airway management.

Purpose: The purpose of this study was to analyze the cardiopulmonary resuscitation skills and teamwork of nurses in simulated cardiac arrests in the hospital. Methods: A descriptive study was conducted with 35 teams of 3 to 4 registered nurses each in a university hospital located in Seoul. A mannequin simulator was used to enact simulated cardiac arrest. Assessment included critical actions, time elapsed to initiation of critical actions, quality of cardiac compression, and teamwork which comprised leadership behavior and communication among team members. Results: Among the 35 teams, 54% recognized apnea, 43% determined pulselessness. Eighty percent of the teams compressed at an average elapsed time of $108{\pm}75$ seconds with 35%, 36%, and 67% mean rates of correct compression depth, rate, and placement, respectively. Thirty-seven percent of the teams defibrillated at $224{\pm}67$ seconds. Leadership behavior and communication among team members were absent in 63% and 69% of the teams, respectively. Conclusion: The skills of the nurses in this study cannot be considered adequate in terms of appropriate and timely actions required for resuscitation. Future resuscitation education should focus on improving the quality of cardiopulmonary resuscitation including team performance targeting the first responders of cardiac arrest.

We developed fog detection algorithm (KNU_FDA) based on the optical and textural properties of fog using satellite (COMS) and ground observation data. The optical properties are dual channel difference (DCD: BT3.7 - BT11) and albedo, and the textural properties are normalized local standard deviation of IR1 and visible channels. Temperature difference between air temperature and BT11 is applied to discriminate the fog from other clouds. Fog detection is performed according to the solar zenith angle of pixel because of the different availability of satellite data: day, night and dawn/dusk. Post-processing is also performed to increase the probability of detection (POD), in particular, at the edge of main fog area. The fog probability is calculated by the weighted sum of threshold tests. The initial threshold and weighting values are optimized using sensitivity tests for the varying threshold values using receiver operating characteristic analysis. The validation results with ground visibility data for the validation cases showed that the performance of KNU_FDA show relatively consistent detection skills but it clearly depends on the fog types and time of day. The average POD and FAR (False Alarm Ratio) for the training and validation cases are ranged from 0.76 to 0.90 and from 0.41 to 0.63, respectively. In general, the performance is relatively good for the fog without high cloud and strong fog but that is significantly decreased for the weak fog. In order to improve the detection skills and stability, optimization of threshold and weighting values are needed through the various training cases.

This study aims to compare the performance of syllable identification task according to auditory and visual stimuli presentation methods and syllable position. Twenty-two typically developing children (age 4-6) participated in the study. Three-syllable words were used to identify the first syllable and the final syllable in each word with auditory and visual stimuli. For the auditory stimuli presentation, the researcher presented the test word only with oral speech. For the visual stimuli presentation, the test words were presented as a picture, and asked each child to choose appropriate pictures for the task. The results showed that when tasks were presented visually, the performances of phonological awareness were significantly higher than in presenting with auditory stimuli. Also, the performances of the first syllable identification were significantly higher than those of the last syllable identification. When phonological awareness task are presented by auditory stimuli, it is necessary to go through all the steps of the speech production process. Therefore, the phonological awareness performance by auditory stimuli may be low due to the weakness of the other stages in the speech production process. When phonological awareness tasks are presented using visual picture stimuli, it can be performed directly at the phonological representation stage without going through the peripheral auditory processing, phonological recognition, and motor programming. This study suggests that phonological awareness skills can be different depending on the methods of stimulus presentation and syllable position of the tasks. The comparison of performances between visual and auditory stimulus tasks will help identify where children may show weakness and vulnerability in speech production process.
