Purpose: This study was done to examine the effects of information searches from media as communication cues for health behavior, specifically smoking, drinking liquor, cancer examinations, and regular exercise. Methods: Data were collected through a web survey with a sample size of 600 and analyzed using SPSS 18.0. Results: The results show that the newspaper as a communication cue has an effect on health behavior such as regular exercise and smoking, whereas television only affects regular exercise. Conclusion: The results indicate that there are differences between media as communication cues to improve health behavior and that messages related to health information should be exposed with cautious consideration to media choice so as to increase the effects of message. Managerial implications of the study results are suggested.

This study examines the effects of the public's perception of emergency medical service (EMS) on the public health system's brand equity and the moderating effect of governance on this relationship using Keller's customer-based brand equity model. It uses four EMS functions: rescue/first-aid and transfer activities; disaster prevention, preparation, and response activities; educational activities in urgent situations; and medical treatment in emergency rooms to examine the effects of them on brand meaning of the public health system. Our findings are important for understanding the public as customers of the public health system and devising and/ or adapting healthcare policies and marketing strategies to develop brand equity and increase customers' loyalty to the public health system.

Aspects of health food intake were investigated by conducting a questionnaire survey with over 480 of adults in Taejon and the data were analyzed by $\chi$$^2$-test, t-test and ANOVA, using an SAS program. Eighty two percent of the subjects had taken some kind of health food. The health foods they took frequently were, for example, health drinks, green tea, ginseng products, dietary fiber drinks, honey, general tea, vitamin B, vitamin C, and tonic medicines. The main reason for taking health foods was recovery from fatigue and the frequency of taking health foods was one time per day. Most of the subjects took health foods without knowledge of their components or effects. When they health foods with a perceived knowledge of their components and effects, they responded that the health foods were very helpful for them. Twenty percent of subjects experienced side effects, such as diarrhea, stomachache, headache, nettle rash, and stomach cramps. Information on health foods was obtained mainly from friends or family. The user group showed higher intention to continue health food intake than non users(p < 0.001). Health foods were taken without any knowledge about them. Health food intake was significantly correlated with consideration of disease, suffering or disease, medical examination, and self-perceived health status, but not with food habits and health food knowledge. As for the results from the adults consumption pattern of health food, an education program should be developed to choose proper health foods according to the consumers dietary life and health conditions. Also a proper guide line should be established to be chosen the authorized health foods.

We analyze the determinants of obesity and the chronic diseases using the Korea Health Panel data. Also we analyze the effect of obesity and the chronic diseases on the health care expenditures. Through this study, to reduce the health care expenditures, we suggest the policy implication that might curb the obesity and the chronic diseases. We estimate the determinants of obesity, the chronic diseases, and the health care expenditures using 2SLS (two stage least squares) estimation method under the simultaneous equations framework. Result says that obesity and chronic diseases significantly have positive effects on the health care expenditures. Also the determinants of the health care expenditures that have positive effects are age, income and health care utilization variables.

Objectives: To investigate the association between psychological distress and obesity among law enforcement officers (LEOs) in the United States. Methods: Self-reported data on psychological distress based on six key questions were obtained from LEOs who participated in the National Health Interview Survey (2004-2010). We used Prochaska's cut-point of a Kessler 6 score ${\geq}5$ for moderate/high mental distress in our analysis. Mean levels of body mass index (BMI) were compared across three levels of psychological distress. Results: The average age of LEOs (n = 929) was 39.3 years; 25% were female. Overall, 8.1% of LEOs had moderate or high psychological distress; 37.5% were obese (BMI ${\geq}30$). Mean BMI increased with increasing psychological distress (no distress, BMI = $27.2kg/m^2$; mild distress, $27.6kg/m^2$; and moderate/high distress, $33.1kg/m^2$; p = 0.016) after adjustment for age, race, income, and education level among female officers only. Physical activity modified the association between psychological distress and BMI but only among male LEOs (interaction p = 0.002). Among male LEOs reporting low physical activity, psychological distress was positively associated with BMI ($30.3kg/m^2$ for no distress, 30.7 for mild distress, 31.8 for moderate/high distress; p = 0.179) after adjustment, but not significantly. This association was not significant among males reporting high physical activity. Conclusion: Mean BMI significantly increased as psychological distress increased among female LEOs. A longitudinal study design may reveal the directionality of this association as well as the potential role that physical activity might play in this association.

This study was conducted on 350 students of health and medical department of universities in Busan from June 3, 2013 to June 21, 2013, and a total of 350 questionnaires were researched. Among them 337 responses were used after 13 unfaithful responses were excluded. The effects of oral health belief on use of dental service of students of health and medical department of universities were examined and analyzed to provide basic data which can be used to expand understanding about oral health belief, to promote changes in behaviors regarding oral health and to improve oral health of the public. Collected data was analyzed through SPSS (Statistical Packages for Social Science 15.0. SPSS Inc. USA). For verification of differences of oral health belief depending on general matters and oral health behavior, t-test and ANOVA analysis were conducted, and for examination of the effects of oral health belief on use of medical service, logistic regression and regression analysis were conducted. The study results suggest that those who had higher sensitivity among oral health belief variables had higher probability of needing dental treatment and seeing the dentist immediately. And those who showed higher sensitivity and importance had higher frequency of seeing the dentist for six months. Future studies need to be conducted on the methods to change oral health belief for sustainable and systematic oral health enhancement in consideration of the factors affecting oral health belief and oral health behavior of the students of dental hygiene department.

Background: Epidemiology is a fundamental study of public health, including environmental health, since the features and causes of diseases discovered through epidemiology provide crucial information for developing successful disease prevention strategies. Objectives: This paper tried to define the role and function of epidemiologic research in the field of environmental health, summarize examples of epidemiological studies with regard to selected environmental health events in South Korea, and address important issues that should be considered when conducting epidemiological research in the future. Methods: Epidemiological studies of selected environmental health events were reviewed and summarized in terms of their contribution to environmental health in South Korea. Based on the information, important issues were suggested for future epidemiological studies in environmental health. Results: The role and function of epidemiologic research in the field of environmental health includes the systematic description of the health effects caused by environmental exposure, verification of the causal relationship between environmental exposure and health effects, and provision of background data for conducting prevention strategies and developing policies. A number of epidemiological studies have contributed to characterizing and assessing the environmental risks involved in a series of environmental health events in South Korea. Conclusions: Important issues for future epidemiological studies may include health effects from chronic low-level environmental exposure, application of analytical epidemiology to elucidate causal relationships, use of exposure/disease/susceptibility biomarkers, accurate reconstruction of past exposure status, cohort recruitment and long-term follow-up, and in-advance surveillance of diseases with environmental causes.

This study sought to determine whether there were mediating effects on both mental health and sleep problems as induced by COVID-19 fears and its effects on preventive practices. The participants were 310 adults living in the Seoul/Gyeonggi Province. For data collection, an online survey was conducted using a semi-structured questionnaire. The collected data were analyzed using PROCESS Macro (Model 6) to validate the dual mediating effects. This study analyzed the direct effects of COVID-19 fears on the mental health problems, sleep problems and preventive practices. Both mental health and sleep problems had dual mediating effects in the influence of COVID-19 fears on preventive practices. Preventive practice has shown that the mediated effects of mental health problems play a strong role in instances when COVID-19 fears increase.

Objectives: Waste treatment by incineration is gradually increasing as the emission of harmful substances has decreased owing to developments in incineration technology. However, residents living near incinerators continue to express anxiety regarding the effects on their health. Therefore, we attempted to summarize the health impact of incinerators by comprehensively reviewing the recently reported literature. Methods: Sixty-two epidemiological research papers related to incineration and health effects were selected from the Google Scholar database and analyzed (from between January 2001 and December 2019). Results: When compared to older incinerators, newer incinerators established after 2000 are considered relatively safe in terms of health effects. Nevertheless, there have been some studies that have linked them to various diseases, such as malignant tumors including soft tissue cancer and non-Hodgkin's lymphoma, reproductive disorders, respiratory diseases, and more. In addition, incinerator workers and local residents are considered to be exposed to dioxins and some heavy metals from the incinerator. Since most studies included subjects exposed to older incinerators, it is difficult to apply these results to the health impact assessment of new incinerators. However, it is not appropriate to conclude that new incinerators made with state-of-the-art technology are safe, as chronic environmental diseases caused by hazardous substances tend to appear only after prolonged exposure. Conclusions: In terms of environmental health, it is necessary to continuously monitor the health effects of incinerators. Also, there is a need to develop a research methodology that can minimize various confounders in incineration-related epidemiological study.
