This Paper presents the severity analysis result of the year 2006 national pedestrian crashes using the data base of 37,589 records prepared for the National Police Bureau. A set of attributing factors considered to affect pedestrian crash patterns were selected, and their contributing effects were investigated by applying the Ordered Logit Model. This model was selected because this model has been able to afford satisfactory results when the dependent variable involved ordered severity levels; fatal, injury, and property- damage-only in this investigation. The investigation has unveiled the followings; First, the pedestrian crash patterns were dependent upon human -drivel and pedestrian- characteristics including gender, age, and drinking conditions. Second, other contributing factors included vehicle, roadway geometric, weather, and hour of day characteristics. Third, seasonal effect was not contributive to crash patterns. Finally, the application of the Ordered Logit Model facilitated the ordered severity level analysis of the pedestrian crash data. This paper concludes that conventional wisdom on the pedestrian crash characteristics is largely truthful. However, this conclusion is limited only to the data used in this analysis, and further research is required for its generalization.

Objectives: This study aims to identify differences in problem gambling among Korean university students by gender and to analyze the relationship between problem gambling and health risk behaviors. Methods: With a sample of 2,026 4-year university students, a questionnaire included CPGI (Canadian Problem Gambling Index) scale and health risk behavior items was administered. Descriptive statistics, t-test, and ANOVA were performed on the data. Results: The prevalence of gambling addiction of male students(14.6%) was two times higher than that of female students(6.6%). The severity of problem gambling was higher in: smokers, those with drug use experience, heavy drinkers, and those with frequently recurring suicidal thoughts, respectively. Conclusions: This study suggests that the problem gambling of university students is a complicated and comprehensive public health problem that is related with health risk behaviors such as alcohol drinking, smoking, drug use, and suicidal thoughts. Prevention strategies and policies are suggested based on the study results.

Objective : The present study had examined the psychiatric symptoms and physical health consequences for the bereaved parents of the high school students who died in the 2014 Sewol ferry accident. Methods : Forty bereaved parents participated in the study. The authors administered self-report questionnaires about the parents' health behaviors and psychiatric symptoms. The authors also conducted laboratory tests to assess the parents' physical health at 18 and 30 months after the accident. Univariate descriptive statistics were performed to report the prevalence and severity of psychiatric symptoms and health-related behaviors. Paired t-test and Mcnemar test were performed to compare the 18-and 30-month findings. Correlation analysis between psychiatric symptoms and laboratory findings were performed to find a relationship between the two variables. Results : At 30 months after the accident, most of the bereaved parents still appeared to suffer from complicated grief (97.5%), post traumatic stress disorder (80%), insomnia (77.5%) and severe depression (62.5%) based on the scores on the Inventory of Complicated Grief (ICG), the PTSD Check List-5 (PCL-5), the Insomnia Severity Index (ISI) and the Patient Health Questionnaire-9 (PHQ-9). One quarter of the bereaved parents reported high-risk drinking, and 47.5% reported increased drinking amount and frequency after the accident. In objective laboratory results, 55% of the bereaved parents were obese as defined by body mass index ${\geq}25$. The parents' mean low-density lipoprotein shows a significant increase over time (118.5 mg/dL at 18 months. vs. 132.5 mg/dL at 30 months. paired t-test t=-4.061, $$p{\leq_-}0.001$$). Total cholesterol and low-density lipoprotein at 30 months after the accident were in clinically borderline high range. In correlation analysis, triglyceride was positively correlated with ISI. Conclusion : The loss of children in the Sewol ferry accident, a disaster caused by human error, continued to have considerable impact on the victims' parents' mental and physical health 18 and 30 months after the accident. A longitudinal study following the parents' physical health would be necessary to investigate the long-term effects of this traumatic experience on physical health.

Purpose: We have implemented a multi-disciplinary Screening, Brief Intervention and Referral to Treatment (SBIRT) protocol to prevent individuals who sustained alcohol-related traumatic injuries. We therefore conducted this single-center, prospective, randomized, controlled trial (RCT) to assess its efficacy. Methods: All the enrolled patients (n=30) were randomized to either the SBIRT group or the control group. In the current RCT, the proportion of the patients who reduced the amount of alcohol consumption and those who received a specialized treatment served as primary outcome measures. Moreover, changes in a 3-item version of the Alcohol Use Disorders Identification Test Consumption (AUDIT-C), Severity of Dependence Scale (SDS) and Kessler Psychological Distress Scale (K-6) scores at 3 months from baseline served as secondary outcome measures. Results: At 3 months, the proportion of the patients who reduced the amount of alcohol consumption was significantly higher in the SBIRT group as compared with the control group (86.7% vs. 57.1%, p=0.02). Moreover, the proportion of the patients who received a specialized treatment was also significantly higher as compared with the control group (26.7% vs. 1.4%, p=0.01). Furthermore, there were significant differences in changes in the AUDIT, SDS and K-6 scores at 3 months from baseline between the two groups (p<0.05). Conclusions: In conclusion, our results indicate that the SBIRT is effective in reducing hazardous and harmful levels of drinking, the degree of alcohol dependence and that of psychological distress in at-risk drinkers.

Many risk factors exist for chemotherapy-induced nausea and vomiting (CINV). This study utilized a multivariate projection technique to identify which risk factors were predictive of CINV in clinical practice. A single-centre, prospective, observational study was conducted from January 2007~July 2010 in Singapore. Patients were on highly (HECs) and moderately emetogenic chemotherapies with/without radiotherapy. Patient demographics and CINV risk factors were documented. Daily recording of CINV events was done using a standardized diary. Principal component (PC) analysis was performed to identify which risk factors could differentiate patients with and without CINV. A total of 710 patients were recruited. Majority were females (67%) and Chinese (84%). Five risk factors were potential CINV predictors: histories of alcohol drinking, chemotherapy-induced nausea, chemotherapy-induced vomiting, fatigue and gender. Period (ex-/current drinkers) and frequency of drinking (social/chronic drinkers) differentiated the CINV endpoints in patients on HECs and anthracycline-based, and XELOX regimens, respectively. Fatigue interference and severity were predictive of CINV in anthracycline-based populations, while the former was predictive in HEC and XELOX populations. PC analysis is a potential technique in analyzing clinical population data, and can provide clinicians with an insight as to what predictors to look out for in the clinical assessment of CINV. We hope that our results will increase the awareness among clinician-scientists regarding the usefulness of this technique in the analysis of clinical data, so that appropriate preventive measures can be taken to improve patients' quality of life.

Objectives: The purpose of the study is to examine the behaviors by the degree od dry mouth related to stress, dry mouth and halitosis. Methods: The subjects were 400 adults. A self-reported questionnaire was completed from August 1 to November 30, 2014. The data were analyzed using SPSS 18.0 program. The questionnaire consisted of eight questions of general characteristics of the subjects, one question of subjective stress symptom, six questions of dry mouth symptom, four questions of dry mouth behavior, and one question of halitosis. Results: There was a significant difference between halitosis and stress in patients having systemic diseases. Stress had a significant difference with gender, income, drinking frequency and alcohol consumption. The degree of dry mouth had a significant difference with gender and age. In dry mouth severity, behavior showed a significant difference with age, education, and times and amount of alcohol consumption. Age had a positive correlation with cigarette consumption and a negative correlation with dry mouth and dry mouth behavior. Cigarette consumption showed a positive correlation with alcohol consumption. Drinking frequency had a positive correlation with alcohol consumption, dry mouth, dry mouth behavior, halitosis and stress. Alcohol consumption had a positive correlation with dry mouth behavior, and dry mouth showed a positive correlation with dry mouth behavior, halitosis and stress. Dry mouth behavior had a positive correlation with halitosis and stress, while halitosis showed a positive correlation with stress. Conclusions: Stress, dry mouth and halitosis were closely correlated. Since stress is the most important variable, stress relief will be the most effective measure to alleviate oral symptoms. Therefore, stress relief measures need to be devised for oral health management in adults having stressful life.

Purpose: This study examined the clinical characteristics of severe elderly poisoning patients to determine the factors that can prevent them. Methods: Data were collected from patients over 65 years of age presenting to the emergency center with poisoning from 2013 to 2018. Their medical records were analyzed retrospectively, and patients with a poisoning severity score of three or more were defined as the severe poisoning group. The risk factors were evaluated by univariate and multivariate analysis. Results: This study analyzed 292 patients, of whom 37 (12.7%) belonged to the severe poisoning group. The severe poisoning group showed a significantly higher association with pesticide poisoning and intentional suicide attempts. Loneliness and somatization were the cause of the suicidal ideas. No significant differences in age, sex, drinking, ingestion time, poisonous materials other than pesticides, and neuropsychological consultation were observed between the two groups. Conclusion: The severe elderly poisoning patients were the result of intentional poisoning for suicide. Loneliness and somatization were the most influential causes of suicidal poisoning. Therefore, psychiatric screening and frequent medical treatment for elderly people are required to prevent severe poisoning in elderly patients.

Objectives: This study was conducted to investigate the effects of personal characteristics and health beliefs on health behaviors of foreign workers living in Korea. Methods: The subjects of this study were foreign workers who understood the purpose of this study and allowed participation in the workplaces in northern Gyeonggi Province. The final subjects were 206, and collected all data were analyzed by SPSS 23.0. Results: The personal characteristics of the subjects were 51.0% for male and 49.0% for female, and the average age was 31.76(±6.96) years old. The mean for each health belief factors was perceived benefits 4.03(±.56), perceived severity 3.75(±.73), perceived susceptibility 3.65(±.64), self-efficacy 3.56(±.83), and perceived barriers 3.34(±.73). The mean of each health behavior factors was non-smoking 4.02(±.83), drinking 3.92(±.80), health responsibility 3.42(±.83), exercise 3.37(±1.01), dietary habits 1.91(±.11), and stress management 1.72(±.27). The correlation between sub-factors of health belief was all at the level of p <0.01. The sub-factors of health belief were health behavior and perceived susceptibility(r=.773, p<0.01), followed by self-efficacy(r=.760, p<0.01), and perceived severity(r=.574, p<0.01). The factors affecting health behavior were self-efficacy(β=.540, p<.001), perceived susceptibility(β=.461, p<.001), perceived benefits(β=.152, p<.05), marriage status(β=-. 100, p <.05), and income(β=-. 120, p <.05) in order. Conclusion: In-depth consideration of factors that can affect the physical, psychological and social health of foreign workers, and various program development and intervention strategies based on these factors should be sought.

The response of ameloblast to long term (3 weeks) exposure to fluoride was examined in continuously erupting mandibular incisors of pregnancy rats as compared to control rats receiving a similar diet (Teklad L-356) but no sodium fluoride in there drinking water. Rats were started on water containing 0 ppm, 100 ppm, 200 ppm, and 300 ppm NaF at the beginning of pregnancy. To examine on the ultrastructural changes of the ameloblast, electron microscopy was used. The results indicated that rat incisors expressed two major changes in normal amelogenesis that could be attributed to chronic fluoride treatment. The fluoride produces marked alteration in the fine structure of ameloblast from teeth of young rats, such as large confluent distensions of the endoplasmic reticulum and swelling of isolated mitochondria, in particular on the morphology of the rough-surfaced endoplasmic reticulum. A graded series of alterations to these organelles were produced, and the severity of the changes would seem to be dependent on dose and time. This experimental data suggested that exposure prolonged of animal to high level of fluoride appears to induce morphological changes in the normal appositional growth and initial mineralization of enamel created during amelogenesis.

Purpose: The purpose of this study was to identify the factors influencing dementia preventive behavior intention of the elderly people based on the Health Belief Model. Methods: The participants included 113 elderly people who met the eligibility criteria. Demographic variables, variables of the Health Belief Model (perceived susceptibility, perceived severity, perceived benefit, perceived barrier, cues to action, general health motivation, and self efficacy), dementia fear and behavioral intention of dementia prevention were examined using structured self-report questionnaires. Statistical analysis was performed by stepwise multiple regression using SPSS for Windows version 21. Results: Self efficacy, alcohol drinking, perceived barrier and education level were significant factors, which explained 32% of the variance in dementia preventive behavior intention. Multiple regression analysis demonstrated that a powerful predictor of dementia preventive behavior intention of the elderly was self efficacy. Conclusion: Developing nursing intervention to enhance self efficacy toward improvement of dementia preventive behavior among elderly people would be recommended.
