Recently there have been an increasing amount of bicycle accidents along with the increased usage of bicycles. Bicycle accidents occur frequently by perpendicular collision at the inner intersection. Bicycle traffic is especially concentrated in residential areas and around schools which results in the vulnerability of cyclists. This paper is to inform the potential risks of collisions between bicycles and cars turning right at the intersections using simulation analysis which focuses on the pavement edge of intersection geometric designs factor and checks on the drivers behavior. The result of the analysis shows that as the curve radius of pavement edge at the intersection becomes larger and the more attention drivers are paying to the rear by turning their heads to the right, the potential risk of collisions between bicycles and cars turning right will decrease.

This study first investigated the relationship among elementary school students' perceived academic stress, self-esteem, and aggression. This study further tested the moderating effect of self-esteem on the relationship between academic stress and aggression. In particular, the moderating effect was tested three times for the three dimensions of aggression (i.e., behavioral aggression, hostility, & anger). A total of 758 (woman 52.1%) 5th to 6th grade elementary school students participated in this study by responding to a questionnaire including measures of academic stress, self-esteem and aggression. The main results of the study were as follows. First, academic stress perceived by the elementary school students showed significant, positive correlations with all of the three dimensions of aggression. Second, the students ' self-esteem was negatively associated with the three aggression dimensions. Third, self-esteem was found to be a significant moderator between academic stress and two dimensions of aggression (hostility & anger), respectively, yet forth, the moderating effect of self-esteem was not significant between academic stress and the behavioral aggression dimension. This study suggests that academic stress can be a risk factor to increase elementary school students' aggression, and that their level of self-esteem can be a buffer to lower the risk. This study provides implications for educators to develop a program that can reduce elementary school students' aggression under academic stress by boosting the students' self-esteem.

The purpose of this study was to investigate the effects of knowledge and risk perception of coronavirus disease-2019 on preventive health behavior among nursing students. The survey participants were 291 students in A city. Data were collected using self-report questionnaires between August 1 and 20, 2020. Data were analyzed using descriptive statistics, the independent t-test, one-way ANOVA, Pearson's correlation coefficients, and stepwise multiple regression in SPSS ver. 18.0. Knowledge of COVID-19 was significantly dependent on age and school records. Risk perceptions were significantly dependent on educational grades. Age, health status, knowledge, and risk perception had significant effects on preventive health behavior, which was found to be positively correlated with knowledge and risk perception. Stepwise multiple regression analysis revealed that age significantly predicted preventive health behavior (β=.188, p<.01), health status (β=-.245, p<.001), knowledge (β=.254, p<.001), and risk perception (β=.191, p<.001) that it accounted for 18.9% (F=17.904, p<.001) of the variance. An educational program is required to enhance the preventive health behavior of nursing students in a background of COVID-2019 that considers student age, health level, knowledge, and perception of risk.

The purpose of this study was to develop a school violence prevention program featuring the Practical Action Teaching Model(hereafter, PATM) for middle school students to prevent school violence by Home Economics Education. To accomplish this purpose, the processes of analysis, design, development, and evaluation based on ADDIE were conducted. The validity of the program was evaluated twice by Home Economics education experts(36 experts for the first group and 10 experts for the second group) and the contents of the program were modified according to the comments from the evaluators. The school violence prevention program in Home Economics classes consisted of 5 topics such as changing perception on school violence, enhancing self-esteem, relating with others, practicing consideration and sharing, and strengthening the will of preventing school violence. Twenty-four units were developed with 7 practical problems(What should I do to make friends to help with each other?, What should I do to establish positive self-concept?, What should I do to communicate to build good relationship?, What should I do to solve the conflicts peacefully?, What should I do to practice consideration and sharing in food consumption?, and What should I do to practice consideration and sharing in clothing?) in 5 topic areas. Teaching-learning plans included four steps such as problem perception, practical reasoning, action, and evaluation that comprise PATM to solve the practical problems. Every step of the teaching-learning plan consisted of questions for practical reasoning and activity assignments. Materials for students and teachers were developed. Materials for students comprised 80 pieces in total including student activity, reading, movie, and clips to make students enhance understanding and interest. Materials for teachers comprised 35 pieces in total such as rationales, newspaper articles, and movies that make teachers that lesson teaching loads and were helpful for teachers. The PATM was incorporated into developing the program and a Likert-scale was used to assess usefulness, applicability, appropriateness, fidelity, substantiality, and validity of this program. This program gained more than 4.00 on a 1-5 Likert scale. This result indicated that program is expected to be effective and useful to school violence prevention.

Suicide is the leading cause of death among Korean adolescents. There is a growing interest in the role of loneliness as a risk factor for suicide ideation and depressive symptoms. However, little is known in the Korean context. This study analyzed a total of 109,796 respondents from the Korea Youth Health Behavior Survey in 2020 and 2021. Multiple logistic regression models were implemented to test the association between loneliness and either of suicidal ideation and depressive mood. Covariates included demographic characteristics, school enrolled, household income, living arrangement, self-rated health, and the number of times treated for violence. Adjusted odd ratio (OR) and 95% confidence intervals (CI) were computed. 12.0% of adolescents reported to have felt lonely frequently and 3.0% always. 11.8% and 26.0% had suicidal ideation and depressive mood, respectively. The prevalence of suicidal ideation was higher in the always-lonely adolescents (52.6%) than in the frequently-lonely adolescents (35.1%). The always-lonely adolescents were nearly 30 times more likely to have suicidal ideation (OR=30.7; 95% CI, 27.1 - 34.8) and to feel depressed (OR=32.5; 95% CI, 29.2 - 36.4) than adolescents who felt never lonely. In conclusion, Loneliness was a major risk factor for suicidal ideation and depressive mood among Korean adolescents. Monitoring and addressing the condition of loneliness may help reduce suicidal ideation and depressive mood.

The purpose of this study was to investigate the risk factors of pregnancy and the relationship between pregnancy experience and suicidal behavior in 284 pregnancy experienced adolescents aged 13-19 years. The suicidal ideation was 57.8%, the suicide plan was 37.7% and the suicide attempt was 37.3% among female adolescents with pregnancy experience. By multivariate logistic regression analysis, female adolescents who experienced pregnancy had 1.44 times more suicidal ideation, 2.39 times more suicide plans, and 2.38 times more suicide attempts than those without suicidal thoughts, plans and attempts. Because of the high correlation between pregnancy experience and suicidal behavior in female adolescents, school and education authorities need systematic education and countermeasures to prevent adolescents' pregnancy and risk of suicide after pregnancy. And above all, convergent support and interest in home, school and community comprehensive area should be supported.

This study examined the health conditions of schoolteachers in terms of the prevalence rate and risk factors for liver disease. A cohort design was conducted for 21,319 teachers who were born from 1953 to 1957. The cohort was constructed for teachers who had no disease history such as liver disease, hypertension, cerebral vascular disease, heart disease, diabetes mellitus and cancer, and had 'normal' results from liver disease examinations in 1998. They were followed up from 1998 to 2000. SAS 6.12 was used for the data analysis. The results were as follows; (1) Prevalence rates of liver disease per 1,000 people in 1998 were 43.0. (2) The 2-year cumulative incidence of liver disease was 433/16,103(26.9/1000 persons). (3) Factors such as sex, age, school type(private or public), drinking, smoking, exercise, BMI, weight gain, fasting-blood sugar levels and total cholesterol levels were statistically significant. The significant risk factors of liver disease be identified from the multiple logistic regression analysis were age, sex(male), drinking, smoking, BMI, weight gain, fasting-blood sugar levels, and total cholesterol levels.

Purpose: The purpose of this study was to identify the prevalence, subtypes and risk factors of Irritable Bowel Syndrome (IBS) among male adolescents. Methods: The survey was conducted on male adolescents (n=441) attending a high school. Rome IV criteria was used to diagnose IBS. Data on health promoting behaviors, psychological distress, sleep hygiene practices were collected using self-administered structured questionnaires. Results: The prevalence of IBS was 11.1% and the subtypes were mixed (77.5%), unclassified (10.2%), diarrhea-predominant (8.2%), and constipation-predominant (4.1%). Risk factors influencing IBS were sleeping time (Odds Ratio [OR]=1.00, 95% Confidence Interval [CI]: 0.99~1.00), anxiety, a subfactor under psychological distress (OR=1.12, 95% CI: 1.02~1.22), and arousal-related behaviors, a subfactor under sleep hygiene practices (OR=1.10, 95% CI: 1.03~1.17). Conclusion: Our findings indicated that IBS is a common problem in male adolescents. It is necessary to develop school-based intervention strategies addressing sleeping time, anxiety and arousal-related behaviors in order to prevent and improve IBS in male adolescents.
