Background: Sunburn is the main avoidable cause of skin cancer. Beach lifeguards spend many hours exposed to the effects of solar radiation during their work day, precisely at times of the year when levels of solar irradiation are highest. The aim of this study is to quantify the risk to beach lifeguards of sun exposure. Methods: A descriptive cross-sectional study was carried out in the Western Costa del Sol, southern Spain, during the summer of 2018. The research subjects were recruited during a skin cancer prevention course for beach lifeguards. All participants were invited to complete a questionnaire on their habits, attitudes, and knowledge related to sun exposure. In addition, ten were specially monitored using personal dosimeters for three consecutive days, and the results were recorded in a photoprotection diary. A descriptive analysis (mean and standard deviation for the quantitative variables) was performed, and inter-group differences were evaluated using the Mann-Whitney U test. Results: Two hundred fifteen lifeguards completed the questionnaire, and 109 met the criteria for inclusion in this analysis. The mean age was 23.8 years (SD: 5.1), 78.0% were male, 71.5% were phototype III or IV (Fitzpatrick's phototype), and 77.1% had experienced at least one painful sunburn during the previous summer. The mean daily personal ultraviolet exposure per day, the minimal erythema dose, and the standard erythema dose, in J/m², were 634.7 [standard deviation (SD): 356.2], 2.5 (SD: 1.4) and 6.35 (SD: 3.6), respectively. Conclusion: Beach lifeguards receive very high doses of solar radiation during the work day and experience correspondingly high rates of sunburn. Intervention strategies to modify their sun exposure behavior and working environment are necessary to reduce the risk of skin cancer for these workers and to promote early diagnosis of the disease.

Purpose: This study aimed to identify the influencing factors that affect the radiation protection behavior of nurses, by applying the educational diagnostic stage of the PRECEDE Model. Methods: Participants were 167 nurses working in interventional procedure rooms and operating rooms in general hospitals and university hospitals in Korea. Data were collected from August 30 to September 25, 2019, through self-reporting questionnaires and analyzed with t-test, ANOVA, Pearson's correlation coefficients, and hierarchical multiple regression analysis using the SPSS/WIN 25.0 program. Results: The influencing factor that affects nurses' radiation protection behavior was the radiation protection environment (β=.41, p<.001), accounting for 59.6% of the radiation protection behavior (F=17.34, p<.001). Conclusion: Administrative and financial efforts to create a safe organizational atmosphere and establish a safe radiation protection environment are needed. Moreover, it is necessary to develop guidelines for nursing work in radiology to improve radiation protection behavior and reduce nurses' radiation exposure.

Purpose: This study attempted to determine the factors related to behaviors of reducing exposure to endocrine disrupting chemicals (BRE to EDCs) in pregnancy, based on the PRECEDE model. Methods: A cross-sectional survey was conducted with participants (N=239) who met the medical records and eligibility criteria from the Women's Hospital and Public Health Center. Data were collected using a specially-designed questionnaire based on the PRECEDE model and included BRE to EDCs predisposing factors, reinforcing factors, and enabling factors. The data were analyzed using the chi-square test, independent t-test, one way ANOVA, Pearson's correlation coefficients and a hierarchical multiple regression analysis. Results: In Model I it was found that participation in prenatal education influenced the BRE to EDCs significantly; and a regression showed that the determinant variables accounted for 3.4%. In Model II, the predisposing factors of perceived barriers of BRE to EDCs and environmental self-efficacy were added. It was shown that they significantly influenced BRE to EDCs in the order named, and a regression revealed that increases in the determinant variables accounted for 22.5%. In Model III, to which enabling factors were added, the information acquisition experience of BRE to EDCs interacted significantly with BRE to EDCs and a regression showed an increase in the determinant variables accounting for 25.3%. Conclusion: The results of this study, the content of endocrine disruptors must be included in the prenatal care education program for pregnant women, and it should be composed of contents that can reduce the perceived obstacle to BRE to EDCs, enhance the environmental self-efficacy, and provide the information in regard to reducing exposure to EDCs.

The presence of a porous Si layer(PSL) formed on the surface of crystalline silicon by electrochemical etclling in HF solution is found to enhance the stability of n-Si photoanodes, but porous n-Si thus formed is still liable to corrode upon exposure to excitation light. To improve the stability of the porous n-Si electrodes and to reduce the photo-induced corrosion, we have examined the PEC behavior of porous n-Si modified with polyaniline(PANI) and 3 nm thick layer of Au. Comparisons were made between Au/PSL and PANl/Au/PSL photoelectrodes.

The purpose of this study was to investigate the effect of sexual messages in the media on adolescents' attitudes and behaviors toward sex. Subjects of this study consisted of 488 high school students in Cheong-ju City. The findings of this study were as follows; First, sexual messages in the media influenced-adolescents' attitudes toward sex. The more exposure to sexual messages adolescents had more liberal and permissive attitude toward sex. Secondly, sexual messages in the media also effected adolescents' behaviors toward sex, as well. The less sexual messages that they were exposed to, they displayed less sexual relations and behavior. In particular, the number of sexual materials in mass media, variety of sexual messages, and types of school were significant factors in predicting adolescents' sexual intercourse. The research suggested that sexual messages in the media definitely had an effect on adolescents' attitudes and behaviors toward sex. Therefore, it should be encouraged to take advantage of the television V chip and screening software for computers to reduce inappropriate access for adolescents.

Human exposure to volatile compounds in tap water can occur from inhalation and dermal absorption as well as direct ingestion. The relative contribution to total human exposure from these pathways has been considered to be important especially for VOC's (volatile organic compounds). In an attempt to reduce the uncertainty of the risk assessment, it has been suggested that the exposure assessment process could be significantly improved by adopting Monte-Carlo simulation. However, there is no actual data in Korea for each exposure parameter to determine the level of exposure, and the distributional pattern. Therefore, we surveyed water use patterns and behavior related to multi-route exposure to VOC's in household tap water in Korea, and compared these values to the those in western countries. In the first survey, we calculated daily water intake using data from a sample of 1322 persons of several cities in Korea. In the second survey, we obtained questionnaire data on exposure time for showering, bathing and household activities, and tap water intake from 851households in Korea. In the last survey, we measured the exposure parameters (exposure time, water use rate etc.) related to showers, baths, toilets, dish washing, washing and cooking, and tap water intake was surveyed. Also, the subjects were measured their body weight, height and tidal volume, etc. A diary, a flow meter and a measuring cup were used to measure these values as precisely as possible. Average daily water intake was ranged 0.79-1.71 L/day for adults in three surveys. Tap water intake measured by log-sheet during one week in third survey was 1.26 (average), 1.98 L/day (90 percentlie), respectively. These results were comparable with results from EPA (1.4, 2L/day). The average amount of water used by housewives in the third survey was 515.0 $\pm$ 564.6L/day. In usual activity, the amount of water used in the bathroom, the laundry and the kitchen was 140.0 $\pm$ 538.9, 148.0 $\pm$ 174.5, 229.3 $\pm$ 205.4 L/day, respectively. Exposure parameters such as water intake rate, exposure duration, body weight, inhalation rates in surveyed data of Korean people differed from those published from western countries. This could be attributed to variations in lifestyle, dietary habits and physiological characteristics.

Background: An inability to cope with threatening dental stimuli, i.e., sight, sound, and sensation of airotor, manifests as anxiety and behavioral management problems. Behavior modification techniques involving pre-exposure to dental equipment will give children a first-hand experience of their use, sounds, and clinical effects. The aim of this study was to compare the techniques of Tell-Show-Play-doh, a smartphone dentist game, and a conventional Tell-Show-Do method in the behavior modification of anxious children in the dental operatory. Methods: Sixty children in the age group of 4-8 years, with Frankl's behavior rating score of 2 or 3, requiring Class I and II cavity restorations were divided into three groups. The groups were Group 1: Tell-Show-Play-doh; Group 2: smartphone dentist game; and Group 3: Tell-Show-Do technique and each group comprised of 20 children. Pulse rate, Facial Image Scale (FIS), Frankl's behavior rating scale, and FLACC (Face, Leg, Activity, Cry, Consolability) behavior scales were used to quantify anxious behavior. Operator compliance was recorded through a validated questionnaire. Results: The results showed lower mean pulse rates, lower FIS and FLACC scores, higher percentage of children with Frankl's behavior rating score of 4, and better operator compliance in both the Tell-Show-Play-doh and smartphone dentist game groups than in the conventional Tell-Show-Do group. Conclusion: The Tell-Show-Play-doh and smartphone dentist game techniques are effective tools to reduce dental anxiety in pediatric patients.

The purpose of this study was to examine 1) the relationship between the vegetable eating behavior of care givers and that of children, 2) the effectiveness of nutrition education with vegetable playing using direct visual stimulating programs on vegetable eating behavior of preschool children, and 3) the times and period of nutrition education with vegetable playing for significant changes on vegetable eating behavior. A total number of 56 individuals, aged 42 to 66 months old, participated in this study in which three kinds of vegetables (30 g)/meal were served per individual, and vegetable eating behavior was measured by the residue on the dish during 5 weeks (25 days). To the simple visual stimulating group, vegetable dish was served without education, and other groups included education 1 group (nutrition education 1 time/week), education 2 group (nutrition education 2 times/week), and education 3 group (nutrition education 3 times/week) with simple visual stimulation by the vegetable dish. The results showed 1) the significant relationship (P<0.001) between the vegetable eating behavior of the care giver and that of children by analysis of the questionnaire, 2) the effectiveness of nutrition education using vegetable playing on vegetable eating behavior of preschool children (P<0.05), and 3) the significant changes in vegetable eating behavior by the 3rd week in the education 3 group. This study shows that food neophobia caused behavior problems in children regarding vegetable eating and repeated exposure was able to reduce food neophobia.
