  • Purpose: Recently there are scientific evidences for the health effects of Asian dust-storms. Particularly in 2002, the daily average of PM10 exceeded 600 and 700 μg/m3 in March and April respectively. We examined the effects of Asian dust‐storms on perceived symptoms and preventive behaviors among children, adults, and elders. Method: The subjects of this study were 425 children, 444 adults and 60 elders. A questionnaire survey was carried out on the children and the adults by teachers and on the elders by interviewers to obtain information on demographic variables, perceived symptoms and preventive behaviors, previous respiratory disease, environmental tobacco smoke, and proximity between the house and the road during Asian dust-storms. We analyzed using descriptive statistics, X2 test and multiple logistic regression models. After adjustment for potential confounders, we estimated the odds ratios and 95% confidence intervals of the children and the elders for perceived symptoms and preventive behaviors. Result: The elders had a significantly higher prevalence of respiratory symptoms than the other groups. The children had a significantly higher prevalence than the adults in getting URI (1.51), coughing (1.68), rhinorrhea (1.46), fever (2.39) and medication for allergy or asthma (1.90). The children had better behaviors than the elders in closing windows (3.57), taking less outdoor recreational activity (2.59) and staying home (2.60). Conclusion: This study suggested that children and elders are susceptible to the effects of Asian dust on health. Health educators should inform these populations about the influence of Asian dust and provide health education for preventive behaviors.

  • Purpose: This study was performed to investigate the dietary behaviors and stress-related factors among male and female college students. Methods: A total of 405 college students (male-195, female-210) were recruited, of whom a questionnaire-based survey was conducted. The study investigated the general characteristics, health-related factors, dietary behaviors, and stress-related factors of the respondents. Results: The body mass index was significantly higher in males. The rates of underweight and overweight were significantly different between male and female respondents. The scores for workout frequency, health concerns and health condition were significantly higher in males, while the score for watching TV & playing computer games was significantly higher in females. The scores for meal regularity, frequency of breakfast consumption, and smoking were significantly higher in males. Eating problems showed a significant difference between males and females. The biggest source of stress was social factors, followed by college study and individual factors and the most experienced stress-induced symptom was anxiety, followed by headache and stomachache. The most popular way to overcome stress was taking a rest, followed by drinking & smoking and outdoor activity. The most preferred food under stressful conditions were alcohol or beverages, followed by hot & spicy food and sweet food, which showed a significant difference between males and females. Conclusion: These results indicate that stress affects dietary behaviors, drinking, smoking, and health status. Stress not only changes dietary behaviors, but is also related to health status. Therefore, it is necessary to develop appropriate programs for emotional stability and stress relief targeting college students which provide continuous nutrition education focused on desirable dietary behaviors and nutritional aspects.

  • The importance of emotional intelligence education in the development of children's augmented reality education content is overlooked. Therefore, in-depth research is needed to develop children's emotional intelligence. This study was conducted through theoretical consideration and case analysis. The proposal of this paper is that the augmented reality type for children aged 2 to 7 is suitable for indoor activities with marking recognition technology. To promote an understanding of emotions, a large screen is selected, and emoticon dolls or emoticon books are recommended for learning content. Children aged 7 to 11 are suitable for indoor activities of non-marker recognition technology, and can induce emotional control and emotional recognition through active manipulation. For the learning content, "3D art teaching content" and "Online Classic Musical" are recommended. Children after the age of 11 are suitable for non-marker recognition technology outdoor activities and improve each element of emotional intelligence through interaction with nature and society. For the learning content, 'Forest Play Activity through Art' and 'EQ Theater Play' are recommended. Through this paper, we intend to promote the development of children's augmented reality emotional intelligence education.

  • In this study, natural radioactivity concentrations and dosimetric values of fly ash samples were evaluated for the landfill area of the coal-fired power plant (CFPP) complex at Binh Thuan, Vietnam. The average activity concentrations of 238U, 226Ra, 232Th and 40K were 93, 77, 92 and 938 Bq kg-1, respectively. The average results for radon dose, indoor external, internal, and total effective dose equivalent (TEDE) were 5.27, 1.22, 0.16, and 6.65 mSv y-1, respectively. The average emanation fraction for fly ash were 0.028. The excess lifetime cancer risks (ELCR) were recorded as 20.30×10-3, 4.26×10-3, 0.62×10-3, and 25.61×10-3 for radon, indoor, outdoor exposures, and total ELCR, respectively. The results indicated that the cover of shielding materials above the landfill area significantly decreased the gamma radiation from the ash and slag in the ascending order: Zeolite < PVC < Soil < Concrete. Total dose of all radionuclides in the landfill site reached its peak at 19.8 years. The obtained data are useful for evaluation of radiation safety when fly ash is used for building material as well as the radiation risk and the overload of the landfill area from operation of these plants for population and workers.

  • Purpose: The purpose of this study was to analyze the factors influencing the health promoting behavior(s) of office worker males in the COVID-19 pandemic by applying Pender's health promotion model. Methods: The participants in this study were 149 male office workers at companies located in S, G and S cities. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and a stepwise multiple regression using the SPSS Window 25.0 program. Results: The subject's health promoting behaviors and prior related behaviors (r=.58, p<.001), perceived benefits of action (r=.41, p<.001), self-efficacy (r=.53, p<.001), social support (r=.39, p<.001), self-esteem (r=.47, p<.001) and commitment to a plan of action (r=.67, p<.001) showed a high positive correlation. The factors affecting the subjects' health promoting behaviors were the commitment to a plan of action (𝛽=.35, p<.001), self-esteem (𝛽=.27, p=.005), prior related behavior (𝛽=.26, p<.001), health status (good) (𝛽=.20, p=.001) and self-efficacy (𝛽=.14, p=.047). These variables explained 63.0% of the subjects' health promoting behaviors. Conclusion: During the COVID-19 pandemic, subjects are more likely to be exposed to disease due to reduced outdoor activity time and irregular eating habits due to the strengthening of social distancing. Health promoting behaviors are an important concept that can maintain health and prevent diseases. To improve the health promoting behaviors of men engaged in office work, it is necessary to develop and operate a health promotion behaviors program considering those variables.

  • An understanding of the knowledges, attitudes and perceptions of different populations is key for public health policy makers. Here, a survey was performed on knowledge, attitudes, and perceptions about malaria diagnosis, prevention, control, and treatment. The 407 survey participants included both uninfected inhabitants and patients from 2 cities (Gimpo- and Paju-si) of Northern Gyeonggi-do, known as high-risk areas for vivax malaria. We used community-based study design and non-probability sampling method using the primary data. Association between variables were tested using χ2-tests. In general, the information on malaria reported by the participants in this study was unsystematic and included inaccurate details. The knowledge of malaria symptoms, identified as headache, chills and fever, was high, but the surveyed community lacks knowledge of the specific medications used for malaria treatment, with a large number of respondents having no knowledge of any form of medication. Survey questions with high correct answer rates included questions about easy treatment of malaria in Korea, the high daytime activity of malaria-borne mosquitoes, and the infection risk posed by outdoor activities. However, a large portion of the respondents was unable to provide simple medical and biological information about the disease. This study aimed to comprehensively evaluate the knowledge, attitude, and practical behavior of the surveyed community with respect to malaria and the implications reported here could be applicable to other malaria endemic areas in Korea.

  • Jeju is the largest island in Korea and one of its key tourist attractions. As the number of foreign tourists steadily increases, so does the number of injuries incurred there. Accordingly, this study aimed to describe and compare the characteristics of injuries suffered by foreign tourists versus those of domestic tourists. As a cross-sectional study of a retrospective medical record survey, the study was conducted with reference to the Jeju Injury Surveillance System from the 11-year period of January 2008 to December 2018. The following factors were investigated: demographic data, mechanism of injury, place of occurrence, activity when injured, patient outcome, and mortality. A total of 92,095 injured Jeju Island visitors was recorded during this time, a number that included 88,050 Koreans and 4,045 foreigners. The gender ratio showed similar patterns between the two groups and there were no significant age differences. In both groups, the most common mechanism of injury was collisions/cuts. Also, more foreigners experienced falls than Koreans. Regarding the location, Koreans had the most road accidents, while foreigners were most likely to be injured at outdoor locations, such as seas and rivers. Furthermore, more foreigners experienced severe injuries requiring hospitalization. Notably, this study showed the differences in injury between foreign and Korean tourists visiting Jeju Island and its findings lend support to targeted safety promotion programs.
