Domestic and foreign automakers compete to lead the autonomous vehicle industry through continuously developing self-driving technologies. These self-driving technologies are evolving with dependencies on the connection between vehicles and other objects such as the environment of cars and roads. Therefore, cyber security vulnerabilities become more likely to occur in the self-driving environment, so it is necessary to prepare for them carefully. In this paper, we model the threats in autonomous vehicles and make the checklist to securely countermeasure them.

Purpose: The purpose of this study was to describe the degrees of body image, self esteem and Health Related Quality Of Life (HRQOL), and to identify factors related to these variables in patients with Crohn's disease. Methods: A descriptive cross sectional survey design was used. The 148 participants were the patients with Crohn's disease, recruited conveniently from one metropolitan hospital located in Seoul, Korea. The collected data were analyzed with SPSS/WIN program. Results: Patients with severe illness activity reported significantly lower body images than those of the others. Education levels and working states affected self-esteem positively, while the number of operations and illness activity affected self-esteem negatively. Hospitalization and illness activity affected HRQOL negatively. Body image, self esteem, and HRQOL were positively correlated to each other with statistical significance. Illness activity was a common factor to affect body image, self esteem, and HRQOL. Body image was an influential factor on HRQOL as well as illness activity in patients with Crohn's disease. Conclusion: As a result, this study suggested a necessity for developing an intervention study to lower the illness activity and heighten the body image among the patients with Crohn's disease.

Purpose: This study was conducted to identify factors that influence on self-determination for withdrawal of life-sustaining treatment in the community dwelling elderly. Methods: This study used a descriptive correlational design. A convenience sample of 201 elderly were recruited from a welfare center located in Seoul, Korea. Data collection was done from September 1 to September 18, 2015. Four survey questionnaires were used: Multidimensional Scale of Perceived Social Support (MSPSS), Life Satisfaction Index-Z (LSI-Z), Attitude on Do Not Resuscitate (DNR), and Self-determination for Withdrawing Life-sustaining Treatment. Data analysis was done by t-test, ANOVA, Pearson's correlation, and hierrarchical multiple regression. Results: Hierarchial multiple regression showed that the factors predicting the level of self-determination for withdrawing life-sustaining treatment were educational level, DNR experience in family, life satisfaction, and DNR attitude. These factors explained 44% of the self-determination for withdrawing life-sustaining treatment in community dwelling elderly. Conclusion: The results of this study suggest developing educational programs aiming at changing elderly's DNR attitude positive ways so that they can enhance self-determination for withdrawing life-sustaining treatment. Further study is needed with more elderly population in extended areas.

Purpose: The purpose of this study was to investigate differences in the states of anger, depression, resilience and self-esteem according to type of school violence involving elementary school students. Methods: The participants were 257 elementary school students in the 4th, 5th and 6th grades. Data was collected by structured questionnaires, and analyzed using descriptive statistics, ${\chi}^2$-test, t-test, ANOVA, and Pearson correlation coefficients with the SPSS/WIN 20.0 program. Results: There were significant differences among the states of anger (Fs=16.66, p<.001), depression (Fs=18.04, p<.001), resilience (F=12.77, p<.001) and self-esteem (F=10.39, p<.001) according to the type of school violence. Of all the groups, bully-victim exhibited the highest score for anger and depression, and the lowest score for resilience and self-esteem. Conclusion: Based on the findings, developing intervention programs that consider the psychological characteristics of elementary school students is necessary. Also, the results of this study suggest that integrative programs for students that can enhance resilience and self-esteem, such as self-discovery programs, and reduce anger, such as anger control programs, need to be developed.

Purpose: This study was to identify the effects of self-resilience and social support on reality shock among new graduate nurses. Methods: The data was collected using self-reported questionnaires from a convenience sample of 111 new graduate nurses. The data was analyzed by descriptive statistical, independent t-test, ANOVA, Scheffe test, Pearson correlation coefficient, and multiple regression via the SPSS Window 23.0 program. Results: Among general and work related characteristics, factors that have shown significant differences on reality shock were gender (t=-2.29, p=.024), work unit (t=3.31, p=.023) and whether they are working at unit they desired (t=-5.08, p<.001). Reality shock has shown a negative correlation with self-resilience (r=-.51, p<.001) and social support (r=-.41, p<.001). Factors that affected the reality shock on new graduate nurses were self-resilience (${\beta}=-.43$, p<.001), whether they are working at unit they desired (${\beta}=.35$, p<.001) and their currently work unit (${\beta}=-.17$, p=.028). These factors take into account of 38.0% of overall reality shock. Conclusion: The results suggest that self-resilience, desired unit and current work unit should be considered as factors when developing an intervention to alleviate the reality shock experienced by new graduate nurses.

Purpose: The purpose of this study was to identify relationships among self-esteem, social support, nursing organizational culture, experience of workplace bullying, and the consequences of workplace bullying in hospital nurses, and then to provide basic information for developing workplace bullying prevention programs. Methods: Participants were 122 hospital nurses from three general hospitals. Data collection was done during April and May 2015. Data were collected using self-report questionnaires which were used to identify participants' characteristics, self-esteem, social support, nursing organizational culture, and workplace bullying. Results: Approximately one quarter of the nurses had experienced workplace bullying in the past six months. Hierarchical regression analysis showed that experience of workplace bullying (${\beta}=.45$) and self-esteem (${\beta}=-.31$) explained 53.3% of the variance in consequences of workplace bullying. Conclusion: Based on the findings that experiencing workplace bullying and having a low self-esteem were likely to increase workplace bullying in hospital nurses, there is a need to develop prevention and intervention programs on avoiding or dealing with workplace bullying.

Purpose: This study was performed to identify relationships among stress, hardiness, and the level of self-care in kidney transplant patients and use the results of this study as baseline data for developing self-care promotion programs. Method: Subjects were 41 patients who undergone a kidney transplantation surgery at least one month before and were receiving regular follow-up care via OPD. Four researchers interviewed each subjects by filling out questionnaires. Results: The mean score of the level of stress was 2.32(SD=0.54) on a 4 point scale and the mean score of hardiness was 4.68(SD=0.62) on a 6 point scale. The mean score of self-care among the subjects was 3.83(SD=0.55). There was statistically a significant positive relationship between selfcare and hardiness(r=0.42). Especially, relationships between self-care and commitment (r=.51) and control(r=.36) as the subdimensions of hardiness were significant. The item suggested as most stressful was economic burden and the item suggested as least stressful was sexual activity. Conclusion: Although transplant patients have various stressors, the positive self-care activities of the patients could be increased if the commitment and control were enhanced by proper intervention programs.

Purpose: This study examined diabetes knowledge, self-efficacy, and health promoting behaviors, and investigated factors affecting health-promoting behaviors of middle-aged people. Methods: From August to September 2014, a convenience sample of 264 subjects was recruited from B city and G province. The data analysis was done by ${\chi}^2$ test, t-test, Pearson's correlation coefficient, and stepwise multiple regression. Results: Diabetes knowledge was $11.3{\pm}3.63$ in men and $12.7{\pm}3.74$ in women. The average levels of self-efficacy and health promoting behaviors of subjects were similar with other middle-aged individuals. Diabetes knowledge, self-efficacy, and health promoting behaviors had a positive correlation with each other in both men and women. To test the mediating effect of self-efficacy in the relationship between diabetes knowledge and health promoting behaviors, a Sobel test was performed and Z-scores of 3.698(p<.001) in men and 2.748(p=.006) in women were obtained. Conclusion: Diabetes prevention education is recommended for the middle-aged community. When developing diabetes prevention program for middle-aged people, such programs should consider self-efficacy, especially in women.
