This study aimed to investigate the awareness and performance of safety in operating room nurses. There were 161 operating room nurses from eight general hospitals included for analysis in this study. The data were analyzed with t-test, one-way ANOVA, correlation analysis, and Scheffe's test. The results show that their perception of patient safety was 3.33 out of a total of 5 points. Moreover, the score of safety management activity for patients in the operating room was 4.28 out of 5 points. As the perception of patient safety in operating room nurses was significantly correlated with their safety management activities, nurses with higher awareness of patient safety were found to have higher degree of performance of safety management activities. In conclusion, to improve safety management activities, open discussion about patient safety should be encouraged and periodic education regarding patient safety should be implemented for operating room nurses to increase the perception of patient safety.

This paper evaluated the performance of passenger vehicles with an AEB(Autonomous Emergency Braking) for various pedestrian-vehicle collision situations. The experiment was conducted at a speed of 30-60km/h on a 2017 3,000cc vehicle using a range of collision scenarios. The results showed that the test vehicle stopped before crashing a pedestrian dummy under all scenarios at 30km/h. The test vehicle reduced the speed but crashed the pedestrian dummy in all scenarios at 40-60km/h. From the paired t-test, there was a speed difference from the AEB system at a significant level of 0.05. In addition, the percentage of speed reduction was quite different for each scenario tested. It was concluded that the current AEB system can prevent pedestrian collisions at speed of 30km/h, but cannot prevent collisions with pedestrians at speed of 40-60 km/h.

The impact of childhood experience has lifelong significance on subsequent health and development. Especially, the experience of infant is mostly affected by the quality of parental care and rearing environment. But the new mothers usually do not know what to do because of the lack of experience in these days. Therefore, an educational program regarding maternal role would be necessary. This study was conducted to evaluate the effectiveness of the maternal role education program for mother-infant interaction, child-rearing environment, and infant development. Non-equivalent control group time-series design was used, and Barnard's mother-infant interaction model was used as a conceptual framework of this study. The subjects were the healthy infants weighing over 2,500gm at birth, whose gestational age was more than 37 weeks, and their mothers. The final sample consisted of 19 mother-infant dyads for intervention group and 18 dyads for control group. Data were collected from March 15th to September 3rd in 1999. For the intervention group, programmed education which focused on mother-infant interaction, breast feeding, and infant care was provided before discharge. Telephone counselling was provided within one week after discharge. Home visiting for maternal role education was provided twice, one month and three months postpartum. For the control group, home visiting was also conducted but only for data collection. The data were analyzed using chi-square test and t-test to test the equivalence of two groups, and the effectiveness of intervention program was determined with repeated measure ANCOVA and t-test. The results were as follows: 1. Significant differences were found in mother-infant interaction between two groups(p=.000). It indicates that intervention program was effective in improving mother- infant interaction. In subscale analysis, four out of six subscale showed significant differences between the groups: sensitivity to cues (p=.000), social-emotional growth fostering (p=.000), cognitive growth fostering(p=.000) in mothers, and responsiveness to caregiver (p=.019) in infants. 2. The difference in the mean score of childrearing environment (HOME) between the intervention group and control group was significant(p=.003). When each subscale of HOME was examined individually, intervention group showed significantly higher scores in the diversity of stimulation(p=.000), and mother's involvement(p=.001). 3. Three-month-Infants of the intervention group showed higher GQ in the Griffiths mental development scale(p=.026). In subscale analysis, significant differences were found in the personal-social(p=.005), and the hearing and speech(p=.003). In conclusion, the maternal role education program proved to be effective in promoting the mother-infant interaction, organizing the childrearing environment, and fostering the infant development. These results are very meaningful that we found maternal role education necessary for normal infants' mothers, and that nurses can make a great contribution in promoting health of infants and mothers.

The objective of this study was to investigate the relationship among the variables and effects of depression and physical activity on fatigue in the elderly with chronic disease. A descriptive research design was employed in this study. In total, 500 elderly patients diagnosed with chronic disease were selected from 3 medical centers for the study. The measurements were used to examine their general characteristics, fatigue, depression, and physical activity. To analyze the data, statistical analyses, including ANOVA, t-test, Scheffe's test, Pearson's correlation coefficient, and hierarchical regression analysis, were conducted for the analysis of the data. The results indicated that the age, gender, and educational level in the first step model explained 6% of the effect on fatigue among the elderly with chronic disease. In addition, depression and physical activity in the second step model explained 16% of the effect on fatigue. These findings demonstrate the significance of (considering) depression and physical activity related to care plans when developing health-programs for decreasing fatigue and planning intervention strategies.

This descriptive correlational study was conducted to identify the factors influencing the uncertainty of patients undergoing chemotherapy for lung neoplasms. One hundred and eleven patients were recruited from the chemotherapy clinic of a university hospital. Data were collected from July 25 to December 31, 2014, and analyzed by descriptive statistics, the t-test, ANOVA, the Scheffe test, Pearson's product moment correlation coefficients and multiple regression analysis with SPSS for Windows Version 18.0. The mean score of the uncertainty of the patients undergoing chemotherapy for lung neoplasms was 2.61(${\pm}0.46$), which was higher than that of the patients with other diseases. The uncertainty was positively correlated with the seriousness of the illness (r=.74, p<.01) and consistency of the symptoms (r=.27, p<.01). Multiple regression analysis showed that the (main) factor influencing the uncertainty was the seriousness of the illness, which explained 54% of the uncertainty of the patients undergoing chemotherapy for lung neoplasms. As a result, nursing interventions are needed to reduce the uncertainty of lung neoplasm patients who are receiving chemotherapy. The seriousness of the illness should be considered when developing nursing interventions to reduce the uncertainty of lung neoplasm patients.

This study aimed to identify factors that had an influence on preventive behaviors of Emergency Medical Service students against tuberculosis to promote their preventive behavior. The subjects of the study were 314 students studying emergency medical service from one 4-year college and two 3-year colleges in Jeollabukdo and they were researched with the use of a questionnaire from June 25, to July 6, 2018. For a statistical analysis of the data obtained, this study used SPSS 18.0 and conducted a t-test, an ANOVA, a Pearson's correlation coefficient and a multi-regression test to analyze the data. Pearson's correlation coefficient analysis showed that the preventive behavior levels was significantly correlated with knowledge of tuberculosis (r = 0.268, p <0.001) and attitude (r = 0.394, p<0.001). As results of the multi-regression test, the higher the knowledge of tuberculosis(${\beta}=0.152$, p<0.001) and the higher the attitude(${\beta}=0.052$, p<0.001), the higher the preventive behavior levels. In addition, Students who have experienced tuberculosis in their own or relative's relatives have a high level of prevention behavior(${\beta}=-0.186$, p=0.001). Therefore, it is suggested that organized and consistent education programs to promote knowledge on tuberculosis, change negative perception on it and improve preventive behavior levels should be developed and provided.

The purpose of this study was to examine the reliability and validity of the K-CPQ in 299 children with developmental disorder and non-disabled children to prove their level of participation in Korean children with developmental disabilities. In order to verify the reliability of the K-CPQ, Cronbach ${\alpha}$ was calculated and Pearson correlation analysis was used for test-retest reliability test. As a result, the internal consistency(${\alpha}=.81{\sim}.90$) in each area of K-CPQ was relatively high and the Pearson correlation coefficient (r=.807~.843) in the test-retest reliability test was significant in all areas(p<.01). It showed statistically significant difference in all areas(t=2.32~5.18) in comparison with the non-disabled children group in order to verify the discriminant validity of K-CPQ. For the criterion-related validity of the K-CPQ, Pearson correlation analysis of K-SMS and K-SFA shows statistically significant static correlation(r=.817, r=743) showed(p<.01). Through this study, K-CPQ has been confirmed as a reliable and reasonable assessment tool and we expect that diverse research by K-CPQ will provide appropriate interventions for children with disabilities.
