This paper presents a development of simulation environment for validation of autonomous driving (AD) algorithm based on Robot Operating System (ROS). ROS is one of the commonly-used frameworks utilized to control autonomous vehicles. For the evaluation of AD algorithm, a 3D autonomous driving simulator has been developed based on LGSVL. Two additional sensors are implemented in the simulation vehicle. First, Lidar sensor is mounted on the ego vehicle for real-time driving environment perception. Second, GPS sensor is equipped to estimate ego vehicle's position. With the vehicle sensor configuration in the simulation, the AD algorithm can predict the local environment and determine control commands with motion planning. The simulation environment has been evaluated with lane changing and keeping scenarios. The simulation results show that the proposed 3D simulator can successfully imitate the operation of a real-world vehicle.

Collision detection plays a key role in collision mitigation system. The malfunction of the collision mitigation system can result in another dangerous situation or unexpected feeling to driver and passenger. To prevent this situation, the collision time, offset, and collision decision should be determined from the appropriate collision detection algorithm. This study focuses on a method to determine the time to collision (TTC) and frontal offset (FO) between the ego vehicle and the target object. The path prediction method using the ego vehicle information is proposed to improve the accuracy of TTC and FO. The path prediction method utilizes the ego vehicle motion data for better prediction performance. The proposed algorithm is developed based on laser scanner. The performance of the proposed detection algorithm is validated in simulations and experiments.

This study aimed to verify the positive effects of forest activities for children from economically underprivileged households in local children's centers and the effect of such activities on the protective factors of their development. One hundred and eighty five children participated in the Forest Activities Program, which conducted over a total 8 sessions. Pre-post tests of the subjective well-being scale, DAS, multiple life satisfaction scale, ego-resilience scale were conducted and the children then made picture stories during the program itself. The results of the analysis of differences between pre-post tests were as follows: first, the negative emotions of participating children decreased significantly. Second, the school-satisfaction and self-satisfaction levels of the participating children increased. Third the participating children's positive perceptions of self and interpersonal relationships also increased through the forest activities. Finally, there were differences of the change types of picture stories that children created while they were participating in the program; and these divergences were related to the effectiveness of the program. These forest activities had positive effects upon the economically disadvantaged children who participated in this study. However, in order to increase the effects of such forest activities qualitatively, greater support for the active involvement of children is required.

This study examined the influence of children's self-concept, self-efficacy, self-resiliency and school adjustment on life satisfaction. Data were collected from 582 fifth and sixth graders in Seoul and Gyeonggi-do. The results of this study are as follows. First, self-concept, self-efficacy, and school adjustment were all confirmed as variables that had direct or indirect influence on life satisfaction. Of these, it was found that school adjustment and self-resiliency turned out to have a more direct influence on children's life satisfaction. Second, as for the greatness of direct influence on school adjustment, which mediates the ego-related variables and life satisfaction, self-efficacy, self-resilience, and self-concept proved to be greater in that order. Third, self-concept turned out to be the variable that had the greatest influence on school adjustment and life satisfaction when taking into consideration of both the direct and indirect influence. It was confirmed that it could be more effective to compose an intervention method for the promotion of life satisfaction case by case for short term goals.

This study is a descriptive study to investigate the influence factors on smartphone overdependenceon in male middle school students. A questionnaire survey was conducted on 174 male middle school students about their smartphone overdependence, stress, ego - resilience, and use of smartphone by function. In results, 29.9% (potential risk group 23.6%, high risk group 6.3%) of the male middle school students were the smartphone overdependency risk group. A higher smartphone overdependency was associated with the higher the smartphone usage time per day, the higher the stress level, the higher the grade, and the lower the ego-resilience level. This requires the involvement of appropriate stress coping styles to overcome excessive stress situations. And the development and implementation of an intervention program that increases the level of ego-resilience can be expected to have an effect of controlling the smartphone use time as well as the intervention effect on stress coping.

Purpose: This study was conducted to derive a substantive theory on lived experiences of elderly cancer patients. Methods: The data were collected from February to March 2018 through in-depth personal interviews with 14 elderly cancer patients. The collected data were analyzed based on Corbin and Strauss's grounded theory. Results: The core category was "the journey to find balance in daily lives as a cancer patient by recovering disturbed ego integrity." The core phenomenon was "shattered by suffering from cancer," and the causal conditions were "physical change" and "limitations in daily life." The contextual conditions were "decreased self-esteem," "feelings of guilt toward the family," and the sense of "economic burden." The participants' action and interaction strategies were "maintaining or avoiding social relations," "seeking meaning of the illness," "falling into despair," and "strengthening the willingness to battle the cancer." The intervening conditions were "support from health care providers and family," "dissatisfaction with health care providers," "spiritual help from religion," and "the improvement or worsening of health conditions." The consequences were "having a new insight for life," "living positively along with cancer illness," and "the loss of willingness to live." A summary of the series of processes includes the "crisis stage," "reorganizing stage," and the "ego integration stage." Conclusion: This study explored the holistic process of ego integrity impairment and the recovery experience of elderly cancer patients. This study is expected to be used as a basis for the development of nursing interventions that can support patients when coping with all stages of their cancer illness trajectory.

This study examines the relationships among ego resilience, social support, and psychological well-being of adolescents. In addition, we verify the mediation effect of social support on the relationship between ego resilience and psychological well-being so as to find ways to improve the psychological well-being of adolescents. For this study, I conducted a survey at middle schools in Seoul and Incheon and collected 289 answered questionnaires. For analyses of the survey results, frequency analysis, reliability analysis, correlation analysis, and hierarchical regression analysis were carried out using SPSS 23.0. The results confirmed significant correlations among ego resilience, social support, and psychological well-being of adolescents. Furthermore, social support was found to have a partial mediation effect on the relationship between ego resilience and psychological well-being of adolescents. For improving the psychological well-being of adolescents based on the results of this study, an in-depth counseling program that can strengthen ego resilience in adolescents should be developed and actively used in the education field. Furthermore, various efforts should be made to improve the social support of adolescents, such as the development of a communication program to help students. Specifically, this program should aim to assist students connect with teachers and seniors by strengthening social support from friends and improving the functions of family to provide social and psychological supports.
