In order to make autonomous vehicles more trustworthy, it is necessary to focus on the users of autonomous vehicles. By evaluating the preferences for driving behaviors of autonomous vehicles, we aim to identify driving behaviors that increase the acceptance of users in autonomous vehicles. We implemented two driving behaviors, aggressive and cautious, in a driving simulator and allowed users to experience them. Biometric data was collected during the ride, and pre- and post-riding surveys were conducted. Subjects were categorized into two groups based on their driving habits and analyzed against the collected biometric data. Both aggressive and cautious driving subjects preferred the cautious driving behavior of autonomous vehicles.

Behavioral symptoms are frequent and problematic components of dementia. The aim of this study was to detect behavioral problem of the 25 item of dementia problem behaviour(DPB)assesment scale for demented older adults. Seventy-three patients with dementia staying in the day care center, group home, dementia hospital, nursing home were recruited data on problematic behavior obtained through interviews with their caregiver during 2 months from March to May 2004. Results shows that problematic behaviors common occurring in 95% of subjects. The most frequently exhibited problematic behaviors were repetitive movement(1.05), repetitive questions(1.03), restlessness(1.0). indifference(0.97). shouting/screaming(0.92). Problematic Behaviors of the demented older adults were closely associated to the distress for caregiver. Most distressful ones for caregivers were repetitive questions(1.46), repetitive movement(1.42), shouting/screaming (1.42), indifference(1.41). restlessness(1.41). Problematic Behaviors of the demented older adults were divided into six subdivisions, among those restless behavior was positively correlated with aggressive behavior, nervous symptom and psychotic symptom. and then nervous symptom was interrelated to psychotic symptom(P<0.01). This study has limitation that field study data were derived from various primary caregivers.

This study investigated characteristics of children's coping behaviors in the context of perceived controllability of stress in hassles with parent(s), friend-alienation, friend-conflict, and in learning situations. The subjects were 489 sixth grade children selected from seven elementary schools in Seoul. Statistical analysis was by ANOVA, Scheffe' test, and MANOVA. Major findings were that (1) Active, passive, aggressive, and avoidant coping differed by perceived controllability of stress in all 4 stress situations. The children who perceived a higher level of controllability were more active, and less passive, aggressive, and avoidant in coping with each hassle. (2) Perceived controllability was higher in learning related than in friend-conflict situations. Active, passive, and social support seeking coping behavior was higher in learning related stress situations than in friend-conflict situations. Avoidant coping behavior was lower in learning related than in friend-conflict situations.

A sample of 654 elementary school children(330 boys and 324 girls) and their mothers responded to three questionnaires regarding mother's job satisfaction and parenting behavior and children's problem behavior. Results showed that working mothers perceived themselves as more permissive/neglecting compared with non-working mothers. Children of working mothers perceived themselves as hyperactive, anxious, withdrawn, aggressive, and immature. Parenting of working mothers with higher job satisfaction was more warm/accepting; their daughters perceived themselves as less anxious, withdrawn, and immature than children of mothers with lower job satisfaction. Children of rejecting/restrictive working mothers, especially girls, reported hyperactive, withdrawn, aggressive, and immature behaviors. Children of permissive/neglecting working mothers were immature. Warm/accepting parenting of working mothers played mediating roles between their job satisfaction and maturity of their daughters' behavior.

This research was conducted in order to find out the effects of boys' self-control, their parents' behaviors and marital conflict on boys' aggression. Subtypes of aggression in the present research consist of dimensions of the functions and forms (proactive-overt, proactive-relational, reactive-overt, reactive-relational). The participants of this study were 237 boys in the fifth and sixth grades in elementary schools located in Seoul and Gyeonggi province. The questionnaires were derived and modified from Lee Hong (2009) for boys' aggression, from Ju So Young and Lee Yang Hee (2008) for boys' self-control, from Jun Joo Ram (2008) and Heo Seung Yeon (2009) for maternal behaviors and from Kang Na Jung (2008) for marital conflict. In order to grasp the general characteristics of the participants, frequency and descriptive statistics were used. Also, Pearson's correlation was applied to the relationships amomg boys' self-control, marital behaviors and marital conflict on boys' aggression. Lastly, the variables that can predict boys' aggression were analyzed through multiple regression analysis by SPSS 19.0. The major results of this study were as follows. This research showed that this model fit well for boys. To summarize the important results, what is interesting in the present study is the effect of the mother's role in rearing their sons. It was found that mothers' criticism, negative behaviors, and excessive interference can cause boys' high level of aggressiveness. Also, having parents who fight frequently was strongly associated with boys' relational aggression. An interesting finding is that the mother's support influenced boys' reactive-overt aggression. Lastly, boys' self-control was highly associated with boys' proactive-relational aggression. This research may contribute to understanding boys' aggression' subtypes. To that end, the current results suggest that the dimensions of the functions and forms may be a useful tool in an effort to inform developmental theory and intervention. Also, this research may provide guidance for the resolution of problems caused by boys' aggression. Lastly, it was found that self- control training and parental education programs might prove beneficial for helping aggressive boys to overcome their aggressive impulses.

The aim of this study was to investigate the behavioral changes of laying hens in an aviary system. In this study, 500 laying hens (Hyline brown) were held in an aviary system in a open-type poultry house. The behaviors of laying hens were recorded using CCD cameras and a digital video recorder. The data were scanned every 2 min to obtain an instantaneous behavioral sample. In the behaviors of laying hens, 'Feeding' and 'Drinking' increased from 3 d placing chick and stabilized after 5 d placing chick. 'Perching' increased from 19:00 to 05:00, while 'Nest visiting' increased from 06:00 to 18:00. 'Aggressive behavior' decreased gradually after 5 d placing chick. These results suggest that the behaviors of laying hens are changed rapidly for about 5 days after placing chick and the behaviors of the laying hens are almost stabilized at 5 d placing chick.

This research is a descriptive correlation research to examine the relationship among stress, coping behaviors, and perceived social support in school-age children. Students in third, fourth, and fifth grades at one elementary school in A metropolitan city were included for this research. A researcher of the study visited the elementary school and obtained appropriate approval to conduct this survey. Then, a total of 481 students answered the questionnaire; finally, the questionnaires of 409 students were analyzed after excluding 72 questionnaires due to unreliable responses. Descriptive statistics, T-test, ANOVA, and Pearson's correlation were used to analyze the collected data with SPSS 13.0. In the stress scores, academic stress was associated with the highest score ($9.30{\pm}4.41$). With respect to stress coping behaviors, lower-grade students showed to have significantly higher scores in coping behavior of pursuing social support than higher-grade students (F=3.181, p=.043); male students had higher scores in aggressive coping behavior than female students (t=-3.399, p=.001). Perceived social support scores were higher in the following order: family members ($33.01{\pm}7.61$), friends ($28.43{\pm}7.89$), and teachers ($25.71{\pm}6.30$). Female students had higher scores in perceived social support from friends (t=3.842, p=.000) and teachers (t=3.037, p=.003) than the male students. As the stress scores increased, passive coping behaviors (r=.410, p=.000) and aggressive coping behaviors (r=.445, p=.000) have been significantly increased. As perceived social support is higher, active coping behaviors (r=.455, p=.000) and coping behaviors to pursue social support (r=.429, p=.000) were significantly increased. Therefore, we can conclude that stress management is very significant for children. It would be necessary to develop nursing intervention programs in order to reduce the aggressive and passive coping behaviors of children and encourage perceived social support.
