Purpose: This study is to analyze influencing factors of smoking intention among nonsmoking middle school students with regard to smoking attitude, knowledge and social influence. Methods: Data were collected from non smoking students of 5 middle schools in D metropolitan city. The 1,892 enrolled subjects provided informed voluntary consent prior to completing a structural questionnaire covering smoking attitudes, knowledge, social influences and general characteristics. The data were analysed using SPSS/Win 21.0 program by -test and logistic regression analysis. Results: Among the nonsmoking students, 85.5% never had an intention to smoke. In relation to general characteristics, smoking intention was significantly associated with sex, school records, socioeconomic status, relationship with parents, smoking experience, and smokers around them. In relation to attitude, knowledge, and social influence, smoking intention was significantly associated with a lower attitude score, a lower knowledge score, and a lower social norm. In the logistic regression analysis, smoking intention was associated with a lower attitude score (2.99 times), a lower social norm (2.65 times), being male (2.35 times), low socioeconomic status (2.22 times). and having smoking experience (2.70 times). Conclusion: It is needed to develop promotional strategies that could provide adjusted systematic smoking prevention education for the preferred smoking group and afford smoking prevention programs considering subject characteristics to help young adolescents avoid access to smoking in their early age.

Objectives: Many epidemiological studies have suggested that a variety of medical illnesses are associated with suicide. Investigating the time-varying pattern of medical care utilization prior to death in suicides motivated by physical illnesses would be helpful for developing suicide prevention programs for patients with physical illnesses. Methods: Suicides motivated by physical illnesses were identified by the investigator's note from the National Police Agency, which was linked to the data from the Health Insurance Review and Assessment. We investigated the time-varying patterns of medical care utilization during 1 year prior to suicide using repeated-measures data analysis after adjustment for age, gender, area of residence, and socioeconomic status. Results: Among 1994 suicides for physical illness, 1893 (94.9%) suicides contacted any medical care services and 445 (22.3%) suicides contacted mental health care during 1 year prior to suicide. The number of medical care visits and individual medical expenditures increased as the date of suicide approached (p<0.001). The number of medical care visits for psychiatric disorders prior to suicide significantly increased only in 40- to 64-year-old men (p=0.002), women <40 years old (p=0.011) and women 40 to 64 years old (p= 0.021) after adjustment for residence, socioeconomic status, and morbidity. Conclusions: Most of the suicides motivated by physical illnesses contacted medical care during 1 year prior to suicide, but many of them did not undergo psychiatric evaluation. This underscores the need for programs to provide psychosocial support to patients with physical illnesses.

This research have aimed for analyzing the effect of relative factors on healthy life styles by the income level in a medium-sized city. Especially, the research tried to figure out whether the public health center's health-promotion-activity had different effects on healthy life styles by the income level. The random sampled data of 809 citizens aged between 19 and 69 were analyzed through phone survey by the Korea Gallop inc(surveyed from 2006.10.11 to 10.13). In the low socioeconomic status, the relation between people's positive conception about public health center's health-promoting-program and healthy behavior tendency is low. But in the high socioeconomic status, the relation is high. This result suggest that the effect of public health center's health promotion programs on healthy life styles is different by income level.

Purpose: The aim of this study is to analyze and visualize the distribution of patients visiting the periodontology department at a dental college hospital, using a geographic information system (GIS) to utilize these data in patient care and treatment planning, which may help to assess the risk and prevent periodontal diseases. Methods: Basic patient information data were obtained from Dankook University Dental Hospital, including the unit number, gender, date of birth, and address, down to the dong (neighborhood) administrative district unit, of 306,656 patients who visited the hospital between 2007 and 2014. The data of only 26,457 patients who visited the periodontology department were included in this analysis. The patient distribution was visualized using GIS. Statistical analyses including multiple regression, logistic regression, and geographically weighted regression were performed using SAS 9.3 and ArcGIS 10.1. Five factors, namely proximity, accessibility, age, gender, and socioeconomic status, were investigated as the explanatory variables of the patient distribution. Results: The visualized patient data showed a nationwide scale of the patient distribution. The mean distance from each patient's regional center to the hospital was $30.94{\pm}29.62km$ and was inversely proportional to the number of patients from the respective regions. The distance from a regional center to the adjacent toll gate had various effects depending on the local distance from the hospital. The average age of the patients was $52.41{\pm}12.97years$. Further, a majority of regions showed a male dominance. Personal income had inconsistent results between analyses. Conclusions: The distribution of patients is significantly affected by the proximity, accessibility, age, gender and socioeconomic status of patients, and the patients visiting the periodontology department travelled farther distances than those visiting the other departments. The underlying reason for this needs to be analyzed further.

Cancer is still a threat to human beings. The incidence and mortality rate of cancer have been gradually increasing as the life span has been lengthened. Radiotherapy is one of the most commonly used treatments for cancer. This study explored the influence of social support and stress on sick role behavior of patients receiving radiotherapy for cancer. The subjects for this study were 60 patients undergoing radiotherapy for cancer, selected from the radiotherapy treatment unit of the out patient departments of two major medical centers in Jeonju. Data were collected from February 1 to 28, 1990 by a Likert Scale Questionnaire and an interview schedule designed by the inverstigator. Data analysis included percentages, mean and standard deviation, t or F-test, Pearson Correlation Coefficient and stepwise multiple regression. Results included the following : 1. Support came primarily from sons and daughters (90.1%) ; the type of support was primarily emotional support from friends(60.0%) ; informational support came from health personnel(81.7%) ; and material support was sons and daughters(40.0%) ; satisfaction with support was highest for the spouse(4.02$\pm$.52). 2. Among the patient's demographic status was occupation the was the only socioeconomic characteristic influencing sick role behavior (F＝2.91 , p＝.029). 3. Directly perveived support was positively correlated with sick role behavior (r＝.2374, p＝.034). 4. Stepwise multiple regression was used to determine the predictors of sick role behavior. Directly perceived support was the most significant predictor accounting for the hightest contribution to sick role behavior(5.6%). Directly perceived support. socioeconomic status, perceived stress and indirectly perceived support variables together, accounted for only 6.8% of sick role behavior.

The purpose of this study was to test the revised Health Promotion Model of Pender and to determine the factors to promote health behavior for adolescents' smoking behavior. The subjects of the study was 783 boys of 4 high school students. among 39. schools locating in Daejeon metropolitan city. The data was collected from July 1st to 15th. 1997 by school health nurse The research tool were HPLP of Walker. Pender. General self-efficacy scale of Sherer. control scale was measured by subconcept of hardiness scale of Pollock. and perceived barrier. perceived benefit. activity-related-affect tool were made by researcher via literature review The data were analyzed by SAS program using frequency. t-test. ANOVA. Schefee test. regression. The results were as follows 1. The mean of total health promoting behavior was $2.27\pm.35$. Among sub domain of health promoting behavior, the highest score was interpersonal support$(2.72\pm.60)$. and the lowest was health responsibility $(1.58\pm.44)$. 2. There were statistically significant difference in total health promoting behavior according to religion. parenting style. school performance. girl friend. father's smoking of individual characteristics. 3. The socioeconomic status. smoking, parent pattern. family structure of individual characteristics and experience domain associated with perceived benefit. perceived barrier. activity-related affect. interpersonal influence of behavior-specific cognition and affect domain. The perceived barrier. self-efficacy. girl friend and father's smoking of interpersonal influence. and control explained $25.8\%$ of variance of health promoting behavior. From above results school health nurse has to emphasize on health responsibility for health promotion of adolescent. But they couldn't intervene for parent pattern. socioeconomic status. family structure of individual characteristics and experience domain. it could be possible for school health nurse to promote health of adolescents through improving perceived barrier. also develop program to increase self-efficacy and through parent health class for fathers. Above results point to the importance of including parents in smoking prevention effort targeting adolescents. Because increasing control also promotes health of adolescents. it should be studied further about the specific measure. To verify the variables for increasing the fitness of health promoting model. it needs further replication of the research.

Objectives: To date, studies have not comprehensively demonstrated the relationship between stroke incidence and socioeconomic status. This study investigated stroke incidence by household income level in conjunction with age, sex, and stroke subtype in Korea. Methods: Contributions by the head of household were used as the basis for income levels. Household income levels for 21 766 036 people were classified into 6 groups. The stroke incidences were calculated by household income level, both overall within income categories and further by age group, sex, and stroke subtype. To present the inequalities among the six ranked groups in a single value, the slope index of inequality and relative index of inequality were calculated. Results: In 2005, 57 690 people were first-time stroke patients. The incidences of total stroke for males and females increased as the income level decreased. The incidences of stroke increased as the income level decreased in those 74 years old and under, whereas there was no difference by income levels in those 75 and over. Intracerebral hemorrhage for the males represented the highest inequality among stroke subtypes. Incidences of subarachnoid hemorrhage did not differ by income levels. Conclusions: The incidence of stroke increases as the income level decreases, but it differs according to sex, age, and stroke subtype. The difference in the relative incidence is large for male intracerebral hemorrhage, whereas the difference in the absolute incidence is large for male ischemic stroke.

Objectives : Posttraumatic stress disorder (PTSD) is classified as an anxiety disorder. PTSD occurrence is known to be increased in middle-aged and older people, female, and individuals with a previous history of psychiatric disorders, lower education levels, low socioeconomic status, and severely injured patients. Anxiety symptoms are also related to later development of PTSD. In this study, we investigate the influences of injury severity and sociodemographic factors on severe anxiety in PTSD patients with no previous history of psychiatric disorders. Methods : Forty-one PTSD patients without previous history of psychiatric disorders were recruited from the psychiatric clinic at Chosun University Hospital. Subjects underwent psychiatric and physical examinations including the Injury Severity Score (ISS), Beck Anxiety Inventory (BAI), and Korean-Wechsler Adult Intelligence Scale (K-WAIS). We defined severe anxiety as a BAI scores of 30 or more. Logistic regression analyses and multi-step model selection were applied to identify predictive factors for severe anxiety. Results : In univariate analysis, age, ISS, and socioeconomic status were found to be significant factors. Through multivariate logistic regression analyses and a stepwise model selection, we found the combination of age and ISS to be the best-fitted model for affecting severe anxiety in PTSD patients without a previous history of psychiatric disorders. Conclusion : Our findings suggest that the combination of age and ISS could develop severe anxiety in PTSD patients with no previous history of psychiatric disorders.

Objectives: Several epidemiological studies on medical care utilization prior to suicide have considered the motivation of suicide, but focused on the influence of physical illnesses. Medical care expenditure in suicide completers with non-illness-related causes has not been investigated. Methods: Suicides motivated by non-illness-related factors were identified using the investigator's note from the National Police Agency, which was then linked to the Health Insurance Review and Assessment data. We investigated the medical care expenditures of cases one year prior to committing suicide and conducted a case-control study using conditional logistic regression analysis after adjusting for age, gender, area of residence, and socioeconomic status. Results: Among the 4515 suicides motivated by non-illness-related causes, medical care expenditures increased in only the last 3 months prior to suicide in the adolescent group. In the younger group, the proportion of total medical expenditure for external injuries was higher than that in the older groups. Conditional logistic regression analysis showed significant associations with being a suicide completer and having a rural residence, low socioeconomic status, and high medical care expenditure. After stratification into the four age groups, a significant positive association with medical care expenditures and being a suicide completer was found in the adolescent and young adult groups, but no significant results were found in the elderly groups for both men and women. Conclusions: Younger adults who committed suicide motivated by non-illness-related causes had a higher proportion of external injuries and more medical care expenditures than their controls did. This reinforces the notion that suicide prevention strategies for young people with suicidal risk factors are needed.

This study is to analyze the effects of child's inner risk factors and outer risk factors intermediated by self concept on his or her resiliency at-risk. For this study, the total of 500 students in their fifth and sixth grade of elementary schools in Busan and their parents were sampled, and a measurement tool is question district court. The questionnaire for the parents measured risk factors, and the questionnaire for the students measured self-concept and about the resiliency at-risk. The SPSS for Win 12.0 and AMOS 5.0 were used to analyze the collected data. The result of this study is as follows; First, there is a significant correlation between the sub-factors of inner risk factors, which shows that the risks of students are caused not just by one of the parents but by both of them. Second, all three variables, that is, inner risk factors, self-concepts, and the resiliency at-risk, closely interact one another. The less inner risk factors of the students, the more positive their self-concept and the more the resiliency to the risk. Third, the higher the socioeconomic status (outer risk factors) and the lower the degree of risk of the family, the more positive the self-concept of the students. Fourth, the higher the socioeconomic status(outer risk factors) and the lower the degree of risk of the family, the more the resiliency to the risk.
