Purpose: Smoking among adolescents is a critical healthcare concern that needs to be tackled with respect to not only intrapersonal and interpersonal factors but also socio-cultural factors. This study was to identify the smoking behaviors and amount of tobacco consumption among adolescents, and to investigate the factors associated with the behaviors and amount. Methods: A cross-sectional study was conducted based on the theory of triadic influence using a nationally representative secondary data set, the 2018 Korea Youth Risk Behavior Survey (N=60,040). The analysis was performed by dividing smoking behaviors into lifetime, current, and daily smoking, and smoking amount into light, moderate, and heavy smoking. Descriptive statistics and multinomial logistic regression analyses were conducted. Results: Overall, 8.2%, 3.2% and 3.4% of the adolescents were involved in lifetime, current, and daily smoking, respectively. In addition, 5.3%, 0.8%, and 0.6% of the adolescents were involved in light, moderate, and heavy smoking, respectively. The factor associated with smoking behaviors and the amount of tobacco consumed were gender, academic achievement, depression, living with family, close friend's smoking, violent victimization, household economic status, and school level (all ps<.05). Conclusion: A considerable number of adolescents are engaged in risky smoking behaviors and consume large amounts of tobacco. Adolescents who said yes to peer smoking, violent victimization, not living with their family, and depressive emotions were more likely to engage in risky smoking behaviors and consume large amounts of tobacco. Tailored interventions to decrease smoking should be planed and provided, while considering the school and home environment and individual needs of adolescents.

Objectives: The purpose of this study was to interpret regional disparities in the number of teeth sealed with pit and fissure sealants, identify the factors that affect these disparities and find solutions for the same. Methods: Data were collected from the National Health Insurance Service and Korean statistical information service using metropolis-city-rural area dental health infrastructure variables, regional health behavior variables, and local finance-related variables. Results: In 2015, the number of teeth sealed with pit and fissure sealants per 100 people was higher in the metropolis or city than in the rural area. There was a positive correlation between the number of teeth sealed with pit and fissure sealants and the number of dentists, dental hygienists, dental institutions, standardization rate of subjective awareness of well-being, standardization rate of brushing after lunch, and the proportion of welfare budget in the general budget. There was a negative correlation with the annual standardization rate of health institution use, the standardization rate of unused medical services, and the local government's financial independence. According to the final model of the multiple regression analysis, while the impact of infrastructure on dentistry was not statistically significant, the statistical significance of standardization rate of brushing after lunch, the local government's financial independence, and the proportion of welfare budget in the general budget were maintained. Conclusions: To reduce regional disparities in the volume of use of pit and fissure sealants, it was concluded that it may be effective to select regions with a consideration of the level of regional economic power, implement separate and appropriate policies and projects, and improve the awareness in residents.

In this study, we evaluated the mechanical properties and nitrogen oxides removal characteristics according to the type and incorporation rate of the photocatalyst and investigated the method of separated placement for the production of economical and efficient photocatalyst concrete. As a result, when the photocatalyst incorporation rate was 5%, the highest compressive strength and elastic modulus were measured. As a result of evaluating the nitrogen oxides removal performance by the photocatalytic reaction, as the photocatalyst incorporation rate increased, the nitrogen oxide removal rate increased. At this time, the nitrogen oxides removal performance of photocatalyst P-25 was better than the NP-A. In consideration of economic efficiency, we have provided a method of separated placement for casting a constant thickness of concrete surface with photocatalyst concrete and evaluated the integrated performance at this time. As a result, it appears to be equal to or higher than mechanical performance and durability performance as compared with Plain, and it is judged that the integrated behavior is satisfied.

Consumption habits of children who economic consumption habits has not been established is a very big concern for parents. According to the credit recovery committee (2006) youth consumption behavior and needs assessment of the education of, he answered that 60.9% of young people have experienced the impulse buying. Student consumption of is done in pin money to receive almost to the parent. Most of the pin money, in order to be paid in cash, is often consumed with the payment directly in the offline sales floor. Pin money is, or waste to students senseless consumption, to trick the price of the purchase goods, to parents, so as to require a greater amount without parental monitoring and agree. In this paper, we would like to propose a system to solve the problem of giving the authority to make decisions off-line payment from student to the parent.

Objectives: This study investigated the health and nutritional status of the elderly according to the number of chronic diseases, using data obtained from the Korea National Health and Nutrition Examination Survey 2013~2015. Methods: Data from a total of 2,310 individuals, aged 65 years and over, were used for the analysis. The elders were divided into 0 (n=375), 1 (n=673), 2 (n=637) and 3 or more (n=625) groups, by considering the number of chronic diseases. Results: Compared to other groups, the elderly subjects who were living with their spouse had the highest ratio in group 0 (P < 0.05), whereas subjects without economic activities had highest ratio in 3 or more group (P < 0.05). The EQ-5D index of subjects in the 0 group (0.90 ± 0.01) was higher than that in the 3 or more group (0.86 ± 0.01) (P < 0.05). After adjusting for confounding factors, the energy intake of subjects was determined to be lowest in the 3 or more group (P < 0.05). Protein (P < 0.05) and riboflavin (P < 0.05) intakes of the 3 or more group were also lower than other groups. Conclusions: This study indicates that multimorbidity of the elderly is associated with their health and nutritional status. The nutrients intake of the elderly, especially energy, protein and riboflavin, tended to be lowest in the 3 or more group. Further research is required to elucidate the risk factors related to presence of multimorbidity in the elderly.

This study was attempted to understand the effect of the violence victim experience of Korean adolescents on smoking using the data of the 15th (2019) online youth health behavior survey. The subjects of this study were 57,303 people, and the data were analyzed using the SPSS / Win 26.0 program for frequency analysis of complex samples, cross sample analysis (Rao-Scott ��2 test), and logistic regression analysis of complex samples. The main result was 12.7% of the smoking subjects. Those who smoked were significantly more 9.6% and 22.0%, respectively, compared to those who had no more than 1 or 2 times of violence. Smoking of Korean adolescents adjusted for gender, grade, academic record, economic status, drinking, family living, and usual stress increased the odds ratio for smoking by 1.66 times when the degree of violence damage experience increased by 1 unit. As a result of the above, as the degree of violence victimization of adolescents increases, the likelihood of smoking increases. Therefore, it is necessary to multidisciplinary convergence effort to the prevention and management of violence of adolescents, and to reduce the smoking of adolescents.

Tunnel boring machines combined with the earth pressure balanced shield method (EPB shield TBMs) have been adopted in urban areas as they allow excavation of tunnels with limited ground deformation through continuous and repetitive excavation and support. Nevertheless, the expansion of TBM construction requires much more minor and exquisitely controlled surface settlement to prevent economic loss. Several parametric studies controlling the tunnel's geometry, ground properties, and TBM operational factors assuming ordinary conditions for EPB shield TBM excavation have been conducted, but the impact of excessive excavation on the induced settlement has not been adequately studied. This study conducted a numerical evaluation of surface settlement induced by the ground loss from face imbalance, excessive excavation, and tail void grouting. The numerical model was constructed using FLAC3D and validated by comparing its result with the field data from literature. Then, parametric studies were conducted by controlling the ground stiffness, face pressure, tail void grouting pressure, and additional volume of muck discharge. As a result, the contribution of these operational factors to the surface settlement appeared differently depending on the ground stiffness. Except for the ground stiffness as the dominant factor, the order of variation of surface settlement was investigated, and the volume of additional muck discharge was found to be the largest, followed by the face pressure and tail void grouting pressure. The results from this study are expected to contribute to the development of settlement prediction models and understanding the surface settlement behavior induced by TBM excavation.

The purpose of this study was conducted to identify perceptions about the relationship between poverty and health and examined the attitudes toward poverty among nursing students. This study administered a standardized questionnaire to 198 nursing students at a university. The data were analyzed using SPSS 22.0. The results of the study showed that nursing students recognized the importance of nursing education for poverty. They also recognized that clinical practice and extra-curricular programs such as volunteer activities were necessary for nursing education. Furthermore, they were aware of the vicious cycle of poverty and health; however, their awareness of the health behavior of the poor was insufficient. In the perception of attitudes toward poverty, individual explanations of poverty tended to be more common than structural explanations, and there was a difference in scores according to age, economic level, political orientation, and clinical practice. In conclusion, it is necessary to develop programs, such as multidisciplinary convergence clinical practice education and volunteer activities, to produce competent nurses to health inequity care for the poor.
