Objectives: The purpose of this study is to understand the factors affecting the dual smoking experience of conventional and heat-not-burn tobacco among adolescents with smoking experience. Methods: The study selected 8,691 people with experience in smoking. Data analysis used SPSS 25.0. Logistic regression was performed to identify the factors affecting the dual smoking experience. Results: In this study, the dual smoking experience rate of conventional and heat-not-burn tobacco was 16.3%. The dual smoking experience rate was 5.09 times higher than the number of smokers among friends. The lower the smoking age, the higher the smoking rate, and the longer the smoking days, the higher the dual smoking rate of heat-not-burn cigarettes. Conclusion: We need a peer-to-peer group arbitration program rather than a separate anti-smoking arbitration program for smokers

Objective: Recently, Korean adolescent has the problems of nutrition unbalance due to bad eating habits. Also, single-parent and step-parent families have consistently increased because of the increase of divorce rates. Adolescent who lives with a single or step family tends to have unhealthy behaviors and habits.

Results: After adjusting for socio-demographic variables among boys, family structure was associated with irregular breakfast (living with both parents reference group vs living with single-parent : OR 1.250, 95% CI: 1.142, 1.368). Among girls, after adjusting for control variables, family structure was also associated with irregular breakfast (living with both parents reference group vs living with no both parents : OR 1.409, 95% CI: 1.065, 1.865). Conclusion: According to this study, family structure would be a risk factor of adolescent breakfast habit. Nutrition programs for adolescent should consider these factors.

Purpose: This study aims to substantiate a correlation between the period of living alone in a shabby one-room and a depression experience. Methods: We conducted a cross-sectional study using data from the Korea Homeless Survey carried out by the Korea Institute for Health and Social Affairs in 2016. In the study, the data included 485 survey participants who resided in a single room. The period of single-room occupancy being divided into three groups: less than 1 year, 1 to 4 years, and more than 5 years was considered a primary independent variable. The outcome variable which represented a depression experience was measured by CESD-11(The Center for Epidemiological Studies-Depression Scale). We carried out a Chi-square test and multiple logistic regression to evaluate the association. Results: The rate of depression experienced in this population was 77.5%. Almost 83.9% of the participants were reported as being unable to receive the mental health counselling in the last 12 months. After controlling for covariates, subjects who were living in a single room occupancy for 1-5 years(OR=3.89; 95% CI=1.43-10.56) and more than 5 years(OR=2.71; 95% CI= 1.05-6.95) were found to be more likely to experience depression. Conclusions: The results showed that living alone in a shabby one-room had a high correlation with experiencing depression. We proposed that there is a need to develop a new strategy for mental health promotion program for the poor, vulnerable and deprived population.

Objectives: The purpose of this study is to obtain the basic data for the development of maternal health care by analyzing the status and needs of service target persons in Timor-Leste. Methods: The subjects were selected through the non-probability sampling method applying the FGI. Researchers interviewed 3 maternal health service managers, 6 midwives at Gleno and Railaco Health Centers and 2 women between 15 and 45 years of age. Results: In the results of on-site visit of the delivery facility and the FGI, we found poor sanitation in delivery room, lack of medical equipment related to antenatal consultation and delivery. In the case of the health center manager, the public health center provides various maternity health services, but the lack of the staff has difficulty in providing the service and managing the subjects. Midwives asked for regular maintenance education. Women in child bearing age living in mountainous areas had poor access to delivery facilities and lack of awareness of delivery services. Conclusions: It is necessary to increase the maternity management rate through regular maternity and maternal health check service and application to maternal management database, to improve the sanitation of the maternity clinic in the public health center, to strengthen the midwife competency program.

Objectives: In this study, we tried to analyze the factors affecting Length Of Stay for serious patients in Republic of Korea. Methods: The study included 139,172 serious patients in the 2012-2016 discharge details. Using the SPSS 23.0 program, we conducted a rank regression analysis with social and social･demographic characteristics as control variables, medical institution characteristics and medical use characteristics as independent variables, and Average Length Of Stay as a dependent variable. Results: Average Length Of Stay for participants was found to be 9.92days. And the location and bed size of medical institutions were not statistically significant, the hospitalization path was more urgent(B=0.43) than the outpatient (p<0.001), and there was no secondary diagnosis(B=0.35). However, Average Length Of Stay was higher (p<0.001) than there was no main surgery(B=0.80). After discharge, Average Length Of Stay for funding(B=0.43) and death(B=0.72) was long (p<0.001). Average Length Of Stay for participants was found to be 9.92days. And the location and the bed size of the medical institution were not statistically significant, and the hospitalization pass had longer Length Of Stay for emergency patients(B=0.43) than for outpatients(p<0.001). There was a longer Length Of Stay(B=0.35) than none was diagnosed. There were longer Length Of Stay(p<0.001) than there was no major surgery(B=0.80). After discharge, the outpatients had longer Average Length Of Stay(B=0.43) and deaths(B=0.72) than those who returned home(p<0.001). Conclusion: As a result of analyzing the factors affecting Average Length Of Stay of the participants, it was confirmed that regardless of the location and bed size of medical institutions, hospitalization route, department diagnosis, main surgery, and whereabouts after discharge. Therefore, appropriate interventions and necessary support must be provided so that efficient Length Of Stay can be managed according to the medical use characteristics of serious patient.
