Objectives: The aim of this study was to evaluate the association between Agent Orange exposure and self-reported diseases in Korean Vietnam veterans. Methods: A postal survey of 114 562 Vietnam veterans was conducted. The perceived exposure to Agent Orange was assessed by a 6-item questionnaire. Two proximity-based Agent Orange exposure indices were constructed using division/brigade-level and battalion/ company-level unit information. Adjusted odds ratios (ORs) for age and other confounders were calculated using a logistic regression model. Results: The prevalence of all self-reported diseases showed monotonically increasing trends as the levels of perceived self-reported exposure increased. The ORs for colon cancer (OR, 1.13), leukemia (OR, 1.56), hypertension (OR, 1.03), peripheral vasculopathy (OR, 1.07), enterocolitis (OR, 1.07), peripheral neuropathy (OR, 1.07), multiple nerve palsy (OR, 1.14), multiple sclerosis (OR, 1.24), skin diseases (OR, 1.05), psychotic diseases (OR, 1.07) and lipidemia (OR, 1.05) were significantly elevated for the high exposure group in the division/brigade-level proximity-based exposure analysis, compared to the low exposure group. The ORs for cerebral infarction (OR, 1.08), chronic bronchitis (OR, 1.05), multiple nerve palsy (OR, 1.07), multiple sclerosis (OR, 1.16), skin diseases (OR, 1.05), and lipidemia (OR, 1.05) were significantly elevated for the high exposure group in the battalion/company-level analysis. Conclusions: Korean Vietnam veterans with high exposure to Agent Orange experienced a higher prevalence of several self-reported chronic diseases compared to those with low exposure by proximity-based exposure assessment. The strong positive associations between perceived self-reported exposure and all self-reported diseases should be evaluated with discretion because the likelihood of reporting diseases was directly related to the perceived intensity of Agent Orange exposure.

Background: In monitoring exposure to environmental smoke (ETS), biomarkers can overcome the subjectivity and inaccuracy of self-reporting measurements, and have the advantage of reflecting ETS exposure in all places. This study aims to evaluate the effectiveness of ETS exposure measurement using biomarkers such as urine cotinine. Methods: This study used the Korea National Health and Nutrition Survey data from 2009 to 2018. A total of 28,574 non-smokers with urine cotinine data were selected for the study. The cotinine concentration and ETS exposure rate using urine cotinine was estimated and then compared with the self-reporting measurements. The degree of agreement among measurements of ETS exposure was confirmed. Results: As a result of measuring ETS exposure with urine cotinine, 23,594 (83.8%) out of 28,574 subjects were classified as to exposure groups. This estimate differs significantly from measurements made by self-reporting. In addition, the average concentration of cotinine in non-smokers has decreased to a 10th level over the past 10 years. Based on the biomarker, the sensitivity of the self-reporting was 8.5%-29.0%, the specificity was 16.4%-19.5%, and the kappa value was 2.0%-5.8%. Conclusion: The findings of our study show that self-reporting measurement does not well reflect the extent to which non-smoker's exposure to smoking materials. Whereas cotinine concentration has decreased significantly over the past 10 years, the ETS exposure rate has not reduced. It strongly suggests the need for intervention in the group of non-smokers exposed to low concentrations of smoke. Therefore, an assessment using biomarkers such as cotinine-based measurement should be made in the Health Plan 2030.

The purpose of this study was to investigate the effects of unconditional self-acceptance and self-exposure of trainees on the post-traumatic growth and to develop a program to achieve post-traumatic growth beyond the previous level without suffering from psychopathological consequences such as post-traumatic stress disorder I wanted to help. For this purpose, unconditional self-acceptance, self-exposure, and Korean post-traumatic growth scale were used. First, it was confirmed that unconditional self-acceptance and self-exposure of firefighters are correlated with post-traumatic growth. Second, hierarchical regression analysis showed that unconditional self-acceptance has more influence on self-acceptance and post-traumatic growth than self-acceptance of firefighters. Based on the results of this study, we propose the program development and therapeutic intervention strategies to promote post-traumatic growth of firefighters.

Purpose: This study aimed to examine the factors associated with behavior that reduces exposure to environmental hormones among nursing students. Methods: Data were collected from 160 nursing students in D and B cities, using self-report questionnaires. Data were analyzed using SPSS 22.0, and the analyses included descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient test, and stepwise multiple regression. Results: Behavior that reduces exposure to environmental hormones differed significantly in terms of the participants' knowledge about environmental hormones. Behavior that reduces exposure to environmental hormones was negatively correlated with knowledge of environmental hormones, attitude towards pro-environmental behavior, and environmental self-efficacy; these factors were significant predictors of behavior that reduces exposure to environmental hormones, and accounted for 27.0% of the variance. Conclusion: Environmental self-efficacy was identified as the most significant factor affecting behavior that reduces exposure to environmental hormones in nursing students. Therefore, it is necessary to develop programs to improve pro-environmental behavior and environmental self-efficacy in nursing students.

The purpose of this study is to explore the effects of listening comprehension ability, self-efficacy, comprehension anxiety, and exposure time on Korean language understanding. In order to achieve our goal, listening examinations and surveys were conducted among 95 students from a university in Thailand, studying Korean language. As a result, it was revealed that the most influential factor on one's listening ability was self-efficacy. In addition, when the correlation between listening self-efficacy and other factors was examined, it was shown that there existed a statistically significant relationship. Particularly, listening comprehension anxiety had the most significant correlation with listening self-efficacy. Similarly, cognitive strategy demonstrated a significant correlation with listening self-efficacy. On the other hand, the effects of self-efficacy and other factors on listening scores such as the degree and types of strategy that students used were also studied. The findings revealed that, in most cases, strategy-intensive group's test results were influenced more by exposure time, while the less intensive group's scores were influenced more by their self-efficacy. Finally, after analyzing the effects of time spent on conversing with friends and watching Korean television on listening self-efficacy, it was discovered that both factors had statistically significant relationships with listening self-efficacy. Through this study, such results can be integrated and applied to education in various ways. The most important part for listening comprehension ability is enhancing self-efficacy and in order to do so, the appropriate education methods should be used to reduce listening comprehension anxiety, stimulate strategy use, and increase listening exposure time.

Purpose: The purpose of this study was to identify factors influencing prevention behaviors for particulate matter exposure in young adults. Methods: A convenience sample of 330 young adults was recruited from the community. Data were collected using a structured questionnaire and analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression analysis with the SPSS/WIN 26.0 program. Results: The factors affecting prevention behaviors of particulate matter exposure were self-efficacy (β=.54 p<.001), subjective norm (β=.18, p<.001) and using the air purifier (β=.-17, p<.001). These variables had a 46% variance to explain prevention behaviors for particulate matter exposure. Conclusion: Findings showed that 'self-efficacy' and 'subjective norm' were important factors influencing prevention behaviors of particulate matter exposure in young adults. Thus, we need to consider the positive impact of prevention behaviors of particulate matter exposure and increase the chances of prevention behaviors of particulate matter exposure program for young adults.

This research aimed to understand selfie behavior in social networking sites (SNSs). The research was conducted on the basis of the functional theories of attitude, verified self-presentation attitude, and self-expression attitude that affect selfie behaviors (i.e., taking selfies, posting selfies, and taking selfies for fashion product exposure). The moderating effect of satisfaction toward one's appearance was identified. The participants of the study were SNS users aged 20-30 years who had posted selfies in the past month. A survey was performed using an online panel of an international survey firm. The data were analyzed using hierarchical regression analysis on SPSS 22.0. Results corroborated that self-expression attitude affected the number of selfies taken but not the number of selfies posted and those uploaded for fashion product exposure. Self-presentation attitude exerted a significant effect on the number of selfies posted and those uploaded for fashion product exposure. When satisfaction toward one's appearance was high, self-presentation attitude increased the influence of the behaviors of posting selfies and uploading selfies for fashion product exposure. Self-expression attitude also significantly influenced the number of selfies taken due to the moderating effect of satisfaction toward one's appearance. This research was made meaningful by its quantitative analysis of selfie behavior in SNSs. The results confirmed the different functions of attitudes affecting selfie behavior. With the improved understanding of selfie behavior obtained from this research, Social Media marketing may be carried out in various industrial fields in the future.

The purpose of this study is to ascertain self-healing function on microcracks in bisphenol F-type epoxy-modified mortars using expansive admixtures. The specimens are prepared with various polymer-binder ratios of 0, 5, 10, 20%, expansive admixture contents of 0% and 10%, a sodium carbonate content of 0.25%, and subjected to exposure conditions of CR1, CR2, CR3 and CR4. The specimens are tested for self-healing effect, porosity and FE-SEM analysis. As a result, self-healing effects of bisphenol F-type EPMMs with expansive admixtures are visible in all of the outdoor exposure conditions. In particular, exposure conditions of CR3 and CR4 are most noticeable. And the porosity of EPMMs is reduced with an increase in the polymer-binder ratio, and is considerably smaller than that of unmodified mortar.

The purpose of this study is to examine the aesthetic view towards exposure in the Korean society through the means of analyzing the characteristics of exposure and figuring out the implications expressed in the red carpet fashion of Korean female movie stars. The concept of exposure in fashion was reviewed through previous studies and related publications. The pictures of actresses wearing red carpet evening gowns in Korea's major film festival were collected and analyzed. The results indicated that the meaning of exposure expressed in the red carpet fashion of Korean female movie stars are as follows: First, this leads the trend reflecting the contemporary aesthetic view of exposure as an effective way to show the beauty of the female body. Second, this emphasizes the femininity and expresses eroticism by exposing certain body parts which symbolize the female gender. Third, this shows the narcissistic self conspicuousness as well as the self confidence and self satisfaction. Forth, this displays the playfulness through exposing the body in a unique way. Lastly, the way and level of exposure can be used to maintain or change the public's view upon the celebrity.

Purpose: This study was performed to investigate the quantities of three neo-maternal exposures; visiting frequency, auditory contact and physical contact, and to examine the relationship between the quantities of each exposure and maternal attachment, maternal self-esteem and postpartum depression in 40 mothers of NICU babies during the first week in the NICU. Method: Each neo-maternal exposure was counted at every mother's visit to the newborn and maternal attachment, maternal self-esteem and postpartum depression were measured using the maternal attachment inventory, the maternal self-report inventory and Edinburgh Postpartum Depression Scale (EPDS) on the first and seventh day in the NICU. Result: The Mean of each neo-maternal exposure was 8.77(2.81) for the visiting frequency, 5.82(3.66) for the auditory contact and 5.60(2.89) for the physical contact during 7 days in the NICU. No significant changes were found in the scores of maternal attachment, maternal self-esteem and postpartum depression between the first and the seventh day in the NICU. The quantities of neo-maternal exposures were positively related to the scores of maternal attachment and maternal self-esteem but not related to postpartum depression. Conclusion: The results of the study suggest the lack of early neo-maternal exposure in cases of NICU hospitalization negate its beneficial effects on maternal psychological well-being in increasing maternal attachment and self-esteem. More efforts are neededfor the neo-maternal interaction and the reevaluation of NICU visitation hours in order to promote maternal-infant interaction.
