Purpose: The purpose of this study was to compare the health risk behaviors, mental health and subjective health status of adolescents in multicultural families and monocultural (Korean) families. This study was conducted to prepare basic data for education and policy proposals related to health promotion of adolescents in multicultural families. Methods: The study was a secondary analysis using the raw data of the 15th Youth Risk Behavior Web-based Survey (2019). A complex sample multiple logistic regression analysis was conducted to understand the influence of growing up in a multicultural family on health risk behaviors, mental health and subjective health status by comparing the variables to those of monocultural adolescents. Results: Adolescents from multicultural families had a 3.3 times higher rate of drug use experience, 1.89 times higher rate of sexual experience, and 1.24 times higher rate of not wearing seat belts. In addition, the rate of not washing hands and the rate of suicide attempts were 1.34-1.50 times and 1.62 times higher, respectively, compared to adolescents from monocultural families. Conclusion: This study showed that it is necessary to develop appropriate health promotion programs to solve the problems of drug use, sexual intercourse, not wearing seat belts, not washing hands, and attempting suicides, which are more prevalent among adolescents from multicultural families than from monocultural families. It will serve a basic policy for the long-term development and growth of Korea at this critical time when multicultural adolescents are increasing.

This study evaluated effects of food additive nutrition education on food additives-related knowledge, subjective awareness, and perception and dietary behaviors of food label use and processed-food intake. The study subjects were 5th grade students attending an elementary school in Seoul. A total of 101 subjects were assigned to either education (N = 50) or control (N = 51) group, and 3 food additive nutrition education classes were implemented to the education group. Self-administered questionnaires were collected from all the participants twice, a week before and after the nutrition education to compare the changes between two groups. The food additives-related knowledge and subjective awareness significantly improved in the education group compared to the control group. The changes in perceived harmfulness and perceived necessity for taste were also detected significantly different between the two groups, with more positive changes in the education group. Dietary behaviors of checking food labels and trying to purchase processed-foods with less food additives improved in the education group at a significant level in comparison with the control group. Additionally changes in intake frequency of several processed-food items were significantly different between the groups, again in a more positive direction in the education group. The study findings showed short-term food-additive nutrition education including hands-on activities could positively modify elementary school children's food additives-related knowledge, perception, and certain dietary behaviors, stressing better settlement of in-class nutrition education within an elementary school's education curriculum.

Background: Outdoor workers are at risk of high ultraviolet radiation exposure, and may have difficulty using sun protection. The objectives were to determine the prevalence of sun protection behaviors in a sample of outdoor construction workers, and to assess which factors predict better sun protection practices. Methods: Participants were recruited via construction unions. Workers answered a questionnaire on demographics, skin cancer risk, sun protection behaviors, and job. Sun protection behavior scores (from questions on sunscreen use, sleeved shirt, hat, shade seeking, sunglasses) were calculated by converting Likert-scale answers to scores from 0 to 4, and taking the mean (separately for work and leisure). Determinants of sun protection behavior scores were examined for work and leisure using generalized linear models. Results: Seventy-seven workers had complete questionnaire data (participation 98%). Sun protection behaviors used most often were hats (79% often/always) and sleeved shirts (82% often/always); least prevalent were shade-seeking (8% often/always) and sunscreen (29% often/always). For both work and leisure scores, the strongest predictor was skin type, with fairer-skinned individuals having higher sun protection behavior scores. Workers had higher scores at work than on weekends. Workplaces that required hats and sleeved shirts for safety purposes had higher protection behavior scores. Conclusion: This high-participation rate cohort helps characterize sun protection behaviors among outdoor workers. Workers practiced better sun protection at work than on weekends, suggesting that workplace policies supportive of sun protection could be useful for skin cancer prevention in the construction industry.

This study investigated the use and understanding of food and nutrition labels in 498 female adolescents (middle school students: MS 248, high school students: HS 250) in Gyeonggi-do. Fifty percent of the MS and 47.2% of the HS read food labels, and the most common reasons for reading labels were to find a product's expiration date and price. The food label information considered most important by the subjects was the name of the manufacturing company and expiration date. Over 80% of the subjects read nutrition labels. The MS read nutrition labels to find nutrients and their amounts in foods, while the HS read labels mostly in an effort to control body weight. These subjects gave more attention to calories and fat, the nutrients related to body weight, than to other nutrients. The subjects were highly aware of the necessity and positive effects of nutrition labels, because they believed labels could make it easier for them to choose healthy foods. However, scores for understanding nutrition labels showed the subjects failed to understand label information accurately. Generally, the MS showed better dietary behaviors than HS. But the HS had significantly higher scores than MS for the item "know relative weight with height." Those that read food labels had significantly better BMIs, dietary behaviors, and awareness and understanding of nutrition labels. There were significant positive relationships among awareness & understanding of nutrition labels and subjects' dietary behaviors. The study findings can be utilized to better plan nutrition education programs aiming to improve use and awareness of food and nutrition labels among adolescents.

A growing body of research has focused on the negative effects of Internet gaming. This issue has become an increased public health concern in Korea. However, little is known regarding the positive effect of Internet gaming and its etiology. This study examined the effects of gaming motivations on gaming behaviors based on self-determination theory. Specifically, we investigated the associations of intrinsic and extrinsic gaming motivations with adaptive and maladaptive game uses. A cross-sectional data collected from a sample of 3,000 young adults using 2016 Korean Video Gaming Survey was analyzed. Measurement model analysis and structural equation modeling were conducted as primary analyses. The findings highlight the different effects of intrinsic and extrinsic motivations on gaming behaviors, such as adaptive and maladaptive game uses. Intrinsic motivations, such as experience-seeking and achievement-seeking, were associated with adaptive game use. Meanwhile, extrinsic motivations, such as sensation-seeking and monetary reward-seeking, were associated with maladaptive game use. The findings provide a better understanding of video gaming in light of both adaptive and maladaptive game uses. The implications for practice and policy were discussed.

Purpose: This study examined the relationship among the use of food-related content (FRC), dietary behaviors, and dietary self-efficacy to demonstrate the need for nutrition education to help adolescents build healthy eating habits and provide evidence for developing nutrition education programs for adolescents. Methods: Three hundred and eighty-one high school students in Seoul and Gyeonggi areas participated in the study. The subjects were divided into three groups (low, medium, and high) according to the level of use of the FRC, and their general characteristics, dietary behaviors, and dietary self-efficacy were analyzed. Correlation analysis was performed between FRC usage, dietary behaviors, and dietary self-efficacy, and the mediating effects of dietary self-efficacy on the relationship between the level of the use of FRC and dietary behaviors were estimated. Results: A higher level of FRC usage was associated with an increased daily cost of eating out and snacking, but no difference was observed in the BMI range. The subjects in a group with a high level of FRC usage ate convenience store or instant foods instead of homemade meals (p = 0.033), had a late-night meal or snack (p = 0.024), and turned to emotional eating under stress (p < 0.001) more than those in the low level group. In addition, the high level group checked the nutrition facts label more carefully when purchasing processed foods (p = 0.016) and exercised at least 30 minutes daily, not considering physical education classes (p = 0.057). The higher level of FRC use, the lower the dietary self-efficacy, whereby the subscales 'environmental stimulus control efficacy' and 'affective factor control efficacy' showed complete mediating effects. Conclusion: Given that FRC has been increased recently, adolescents are in need of support to help them control and enhance their dietary self-efficacy as well as develop healthy dietary behaviors through proper nutrition education programs.

Such social structures as bridges, buildings, dams and towers have been transformed by their own load or fundamental ground. They have been behaved by other external causes. These regular or irregular behaviors threaten to do their users safety. Therefore, to monitor the load of the structures or reaction shown by them could help to verify their behaviors. RTK GPS allows the use of a static base station and remote rover unit to allow for data collection within several seconds and in real time. It is useful for monitoring the behaviors of massive structures like bridges. In this Study, Among GPS methods, we used RTK GPS to analyze the precision of monitoring and then on the basis of it, we developed a monitoring system using RTK GPS when measured the behavior of main tower of a suspension bridge by using RTK GPS. Comparing a deviation between observation values, X axis was 1mm, Y axis was 1mm and Z axis 2.2mm. It turned out that it was possible to monitor and measure structures by RTK GPS.

This study measured various types of joint book reading behaviors of parents of preschool children using two different text genres. Participants were the parents of 35 preschool children 4 years of age. Parent-child dyads were videotaped during periods of joint book reading using two different types of text(informational and narrative). Results indicated differences in maternal behavior between the two types of texts. The informational book elicited a higher amount of print concept behaviors and more content behavior while reading the narrative book. Among content-related behaviors parents used more labeling during the informational genre. On the other hand, parents' use of description and judgment were significantly higher in the narrative genre compared with the informational genre.
