This paper presents a comparison among three types of approaches to an ARC (Active Roll Control) with an AARB(Active Anti-Roll Bar) for a vehicle system. Lateral acceleration and road profile are considered as disturbance. The ARC is designed with an LQ SOF (Linear Quadratic Static Output Feedback) control, $H_{\infty}$ control and SMC (Sliding Mode Control). These approaches are compared in terms of rollover prevention and ride comfort. For comparison, Bode plot analysis based on linear model and frequency response analysis based on CarSim simulation are performed.

Purpose: This research was conducted to determine the effects of fall prevention exercise and education on physical fitness, fall efficacy, and fall prevention behavior among community-dwelling older adults. Methods: This study applied nonequivalent control group pretest-posttest design. Data were collected from January 8th to March 4th, 2015. There were 24 subjects in the experimental group and 21 in the control group from two different senior citizen center in B city. The fall prevention program consisted of exercise, education, and telephone coaching was developed using self-efficacy theory: 'Performance accomplishment', 'Vicarious experience', 'Verbal persuasion', 'Emotional arousal'. Then, it was conducted once a week for 8 weeks. Data were analyzed with $x^2$ test and t-test using the SPSS program. Results: The findings indicated that fall prevention program conducted on older adults is good for improving their muscular strength in lower extremities (t=6.25, p<.001), physical balance (t=2.66, p=.014), physical flexibility (t=2.88, p<.001) and fall prevention behavior (t=6.19, p<.001). Conclusion: The fall prevention program can be used for community-dwelling older adults as a nursing intervention that enables older adults to enhance their self-care continuously. It is necessary to conduct a follow-up study to see if a self-help meeting could improve self-efficacy.

Background: This study examined age-group differences in the rate, severity, and cost of injuries among construction workers to support evidence-based worker safety and health interventions in the construction industry. Methods: Ohio workers' compensation claims for construction workers were used to estimate claim rates and costs by age group. We analyzed claims data auto-coded into five event/exposure categories: transportation incidents; slips, trips, and falls (STFs); exposure to harmful substances and environments; contact with objects and equipment (COB); overexertion and bodily reaction. American Community Survey data were used to determine the percentage of workers in each age group. Results: From 2007-2017, among 72,416 accepted injury claims for ~166,000 construction full-time equivalent (FTE) per year, nearly half were caused by COB, followed by STFs (20%) and overexertion (20%). Claim rates related to COB and exposure to harmful substances and environments were highest among those 18-24 years old, with claim rates of 313.5 and 25.9 per 10,000 FTE, respectively. STFs increased with age, with the highest claim rates for those 55-64 years old (94.2 claims per 10,000 FTE). Overexertion claim rates increased and then declined with age, with the highest claim rate for those 35-44 years old (87.3 per 10,000 FTE). While younger workers had higher injury rates, older workers had higher proportions of lost-time claims and higher costs per claim. The total cost per FTE was highest for those 45-54 years old ($1,122 per FTE). Conclusion: The variation in rates of injury types by age suggests that age-specific prevention strategies may be useful.

Purpose: The purpose of this study was to analyze addiction prevention related content shown in middle school text books. Methods: Using a combination of the terms "addiction", "drug", "medicine", "personal preference", "smoking", "drinking", "sex", "misuse" or "abuse" as key words, the researchers screened the table of contents of 23 randomly selected middle school textbooks from the 2009 curriculum. Finally 13 textbooks (physical education=10, health=3) were selected for this study, and analyzed using Krippendorff's contents analysis. Results: Through indepth discussion and investigation of the relevant textbooks, content related to addiction prevention included material addiction (77.8%) and behavioral addiction (22.2%). The construction of addiction prevention in middle school textbooks included understanding addiction, rejection of peer temptation, and empowerment of self-control. Conclusion: When developing an intervention for addiction prevention that targets middle school students, education with accurate addiction information must be considered so that the students have the correct knowledge about addiction and addiction prevention. Additionally, the ability to reject peer temptation when invited to act upon related addiction behaviors should be treated seriously. The empowerment of self-control is also important, and can be promoted through strengthening self-regulation competence.

Purpose: This study aims to identify the effect of pediatric fall prevention education with leaflets and picture books on the fall-related knowledge and preventive behaviors in caregivers of inpatient children. Methods: This study is a non-equivalent control group non-synchronized design. It divided 62 caregivers of inpatient children aged 5 and under into an experimental group and a control group in P general hospital located in B City. Results: Fall related knowledge score in the experimental group was increased by 2 points after the intervention and the score in the comparison group was increased by 0.1 points. The difference after the intervention in fall related knowledge scores between the two groups was statistically significant (t=7.67, p<.001). The fall related prevention behavior score of the experimental group increased by 9.3 points after the intervention, and the score of the comparison group increased by 2.5 points. The difference in the scores of fall related prevention behaviors between the two groups was statistically significant (t=5.71, p<.001). Conclusion: Pediatric inpatient fall prevention education using leaflets and picture books can improve caregivers' fall-related knowledge and preventive behaviors. In turn, this can reduce children's falls in pediatric wards in general hospitals.
