Objectives: This study firstly examined the pattern and prevalence of drinking. Secondly, we examined the sociodemographic and health factors associated with binge drinking and problem drinking among Korean men and women. Methods: Secondary analysis of the 2005 Korea National Health and Nutrition Examination Survey was conducted for 6,613 respondents aged 19 to 64. Results: Prevalence for binge drinking was 59.7% of men and 15.2% of women. Overall, 45.0% of men and 7.1% of women reported problem drinking. For both men and women, being divorced/separated/widowed was associated with binge drinking (OR=1.51 for men, OR=1.91 for women) and problem drinking (OR=1.43 for men, OR=2.12 for women), and smoking was associated with binge drinking (OR=3.20 for men, OR=3.96 for women) and problem drinking (OR=2.39 for men, OR=4.93 for women). Among women, unmarried and less educated increased the risk of binge drinking and problem drinking but being single and education level were not associated with binge drinking and problem drinking in men. Conclusion: There might be sex difference in the relationships between sociodemographic, and health factors and binge drinking, and problem drinking. Our finding suggest that the need to develop appropriate binge drinking prevention and intervention strategies for sex specified groups at greater risk.

The study aimed to measure the levels of radiation protection for radiologists in medical institutions in three environmental categories (physical, administrative and social) and to establish a data base which can be used to increase awareness of environmental radiation protection in medical institutions within Korea. The study surveyed 10% of radiologists working in radiology departments in medical institutions which are supervised by the National Dose Registry overseen by the Korean Food and Drug Administration(KFDA). This study found that the level of environmental radiation protection was higher in the capital area and in larger hospitals. On the other hand, the study shows environmental radiation protection was lower in the Youngnam area and in clinics. Results from the questionnaires indicate the level of environmental radiation protection was higher when radiologists were given an individual dosimeter but lowest when the radiation protection apron quality test was conducted. Environmental radiation protection is an important factor for radiologists to conduct activities in a safe and protected environment. However, this study shows there are differences in the level of environmental radiation protection in medical institutions and location within Korea. In particular, the level of environmental radiation protection was lower in clinics, appropriate intervention strategies befitting these conditions are needed based on medical institution classification and location in order to improve the level of environmental protection.

Background: Adolescent risk behaviors are of concern because they are dangerous in themselves and have negative influences on adult health. Objectives: This study explored six health risk behaviors of a sample representing the adolescent population in Jeju. Methods: Frequency and percentage of risk behaviors were calculated. Additionally, the chi-square test was used to explore whether differences in experimentation with risk behaviors exist relative to gender and schooling levels. Results: There were six major findings in this study: (a) a lower rate of lifetime and current cigarette use among female students compared to male students, (b) a substantial portion of heavy drinkers, (c) a higher rate of lifetime drug use among female students than among male students, (d) a higher prevalence of suicide ideation among female students than among male students, (e) substantial percentages of students who did not usually wear seatbelts, motorcycle helmets, or bicycle helmets, and (f) a substantial portion of students who were not involved in vigorous physical activities. Conclusions: Since a substantial portion of adolescents have been involved with diverse risk behaviors, it is urgent to implement effective intervention strategies to reduce the rates of these behaviors.

Purpose: Few studies have considered the psychosocial work environment factors in relation to employee health. This study explored the relationship between psychosocial work characteristics and self-rated health among Korean employees. Methods: The study population of 21,476 employees was derived from the 2014 Korean Work Environment Survey (KWES). Psychosocial work environment was measured by Copenhagen psychosocial questionnaire scales. Results: Among employees at workplaces (n=21,476), 23.3% rated their health as poor. Among 12 indicators of psychosocial work environment characteristics, 'higher emotional demand', 'demands for hiding emotions', 'work-family conflict', and 'social community at work' were independently associated with risk of poor self-rated health of Korean employees after adjustment of all sociodemographics, work condition characteristics and physical work environment exposure. In addition, higher 'possibilities for development' and 'social support from supervisor' were more likely to decrease the risk of poor health. Conclusion: We suggest that psychosocial work environment is an important determinant of employees' health. The study results provide a good starting point for developing intervention and strategies for health improvement.

Purpose: The purpose of this study was to define and clarify the concept of reality shock in new graduated nurses. Methods: The hybrid model was used to develop the concept of reality shock. The model included a field study. The participants were 9 newly graduated nurses with a nursing career spanning less than a year. Results: The reality shock in newly graduated nurses was identified to have three dimensions and seven attributes. Specifically: 1) the dimension of performance included two attributes (conflict between theory and practice, and being overwhelmed by the workload), 2) the dimension of relationship included three attributes (loss of support, embarrassment from interference, and relational withdrawal), 3) the dimension of expectations included two attributes(value confusions and incongruity in personal life). Conclusion: Newly graduated nurses' reality shock was defined as a state of incongruence in their entire life that the new nurses experienced owing to value confusions that occurred due to the conflicts between theory and practice in an unfamiliar work environment, getting overwhelmed by the workload, and withdrawing establishing relationships with others due to the loss of support and excessive interference. These findings could help develop intervention strategies to decrease reality shock in newly graduated nurses.

This paper presents some simulations of fluxes and pressures in the coronary network, in the case of very severe coronary disease (several stenoses on the left branches and total occlusion of the right coronary artery). In that case, coronary artery bypass graft surgery is the commonly performed procedure. However, the success of the intervention depends on many factors. Modeling of the coronary circulation is thus important since it can help to understand the influence of all these factors on the coronary haemodynamics. We previously developed an analog electrical model that includes the eventual presence of collateral flows, and can describe the different revascularization strategies (two grafts, three grafts, ...). The aim of the present work is to introduce in our simulations the time-dependence of the coronary microvascular resistances, in order to better represent the effect of the systolic ventricular contraction (which induces an elevation of the resistances because the vessels are squeezed).

Purpose: The positive effects of health behaviors in older population are well recognized, but maintenance of health habits was more difficult than initiation. The purposes of the study were to identify predictors of health behavior based on motivation theories, and to analyze predicting power of motivational factors to explain health behaviors in older adults. Methods: The data were collected from older adults either institutionalized or living in the community. Total of 159 subjects with 72 years old in average were recruited for an interview. Hierarchical multiple regression analysis were utilized to analyze the data with age, residential type, and motivational variables. Results: The results of the multiple regression analysis showed that age and residential type explained 3% of variance in health behaviors (F=3.705, p=0.027). When motivational variables were entered, additional 56.9% of variance were explained by the model (F=33.275, p< 0.001). Among motivational variables, perceived benefits was the most important variable (${\beta}=0.346$, t=4.582, p<0.001), followed by self efficacy, emotional salience, and perceived barriers. Conclusion: Considering the importance of each motivational variable, the focus of intervention strategies to assist older adults to maintain health behaviors should be on modifiable and important motivational variables, such as self-efficacy, perceived benefits and barriers, and emotional salience.

Purpose: The purpose of this study was to understand and describe the every day life experience of patients with acute myocardial infarction (AMI) during the recovery period after Percutaneous Coronary Intervention (PCI) using a qualitative approach. Methods: Twelve patients with AMI participated in this study. Their age ranged from 42 to 75. The data were collected by individual in-depth interviews and all interviews were audio-taped and transcribed verbatim. The transcribed data were analyzed using traditional qualitative content analysis. Results: Six sub-themes emerged from the data as follows: Getting to know about illness, getting motivated for health behavior, putting an effort into health behavioral change, having difficulties maintaining health behavior, setting up coping strategies for health behavior and having a need for a tailored education. The results of this study showed how the health behaviors of patients with AMI are related to their every day life experiences. Conclusion: The results of this study could help health professionals to better understand patients with AMI and design effective educational interventions to improve their health behaviors.
