Objectives: Children are more susceptible to heavy metal toxicity than adults. The purpose of this study was to evaluate heavy metal concentrations in the blood of Korean preschoolers and investigate the association between metals in blood and related factors. Methods: A total of 512 subjects from 36 to 83 months of age were sampled. A questionnaire survey was performed and the levels of lead, mercury and cadmium were measured in the blood samples of all subjects. Their parents were interviewed in order to obtain information on basic characteristics, dietary patterns, socio-economic factors, and indoor/outdoor environment of the preschoolers. Multiple linear regression was used to analyze the association between the above factors and lead, mercury or cadmium concentrations. Results: The geometric mean concentrations of lead, mercury and cadmium in the blood were $1.45{\pm}1.58{\mu}g/dL$, $2.14{\pm}1.74{\mu}g/dL$ and $0.23{\pm}1.91{\mu}g/dL$, respectively. Results from multiple linear regression analysis showed that blood lead levels were associated with birth weight and paternal smoking status. Daily mercury intake from food and maternal education were also shown to influence mercury concentrations in blood. Also, blood cadmium concentrations were associated with maternal age and having a bus garage near the place of residence. Conclusion: This study suggests that smoking status, dietary patterns and the environmental status near the residence should be considered as important factors for preventable sources of heavy metal exposure in preschoolers.

The study examined the effects of individual, family, and environmental factors on adolescents' self-esteem. Individual factors were the adolescents' health status and their leisure activity experiences, while the family factors were families' socio-economic status(SES) and parenting styles. Three environmental factors focusing on the adolescents' school environment were studied, and they consisted of academic attachment, peer attachment, and teacher attachment. The study inquiries were as follows: which individual factors had an effect on the adolescents' self-esteem? Which family factors had an effect on the adolescents' self-esteem? Which environmental factors had an effect on the adolescents' self-esteem? Of all the factors considered in this study, which factors had the greatest effect on adolescents' self-esteem? This study used data from the 3rd Korean Child and Youth Panel survey of Korean students in the first grade of middle school, and the data were analyzed using multiple regression analysis using SPSS 18.0. The results were as follows: the most important factor that have an effect on adolescents' self-esteem was parenting style, while peer attachment, health status, and academic attachment were also found to significantly affect adolescents' self-esteem. In the conclusion, the researchers suggest various strategies based on results of the analysis to improve adolescents' self-esteem.

The purpose of this study was to analyze and present the achievements and challenges of the 70th year of the Korean Federation of Teachers' Association (KFTA). The KFTA was founded in 1947 as the Chosun Education Association, and it was the 70th anniversary of its founding in 2017. Throughout its 70?year history, the KFTA, which has emphasized and promoted expertise and professionalism, has continued to improve the professionalism of the teaching profession through research, improve the socio?economic status of teachers, and expand the welfare system in order to improve the quality of teaching and teaching environment. In addition, the KFTA contributed to the development of national education by participating in educational policies to improve education system and educational environment, as well as activities as a professional organization, and has promoted international status through the promotion of international exchange. After analyzing the academic literature and KFTA related data diachronically, this research suggested achievements and challenges as three aspects: the status as teachers' professional organizations, the activities as interests and pressure groups, and the activities as professional organizations.
The purpose of this article is to review the status of designation and preservation, management of national prehistoric sites and to suggest future applications. Prior to the discussion, the overall status of national prehistoric sites was reviewed. Specifically, the current status of designation, designated area, and distribution by region of national prehistoric sites according to the period and nature of the sites were examined in detail. Next, in order to understand the preservation and management of national prehistoric sites, I report the results of field trips to several sites, such as Geomdan-ri in Ulju, Songguk-ri in Buyeo, and Seoktaek-ri in Hongseong, and propose some measures for preservation, maintenance, and management of the remains. Finally, by referring to cases of US national historic sites such as protection, conservation, operation and management system and academic research project of cultural heritage, it is necessary to consider the need for a direction of the utilization that considers both socio-economic aspects as well as education and research on cultural heritage. The active use of cultural heritage can be a measure that leads to the continuous preservation and management of the sites, and ultimately will be a shortcut to increasing the value of national prehistoric sites.
Background: The problem of cancer, especially lung cancer, is very acute in Bangladesh. The present study was conducted to evaluate the risk of lung cancer among Bangladeshi people based on hereditary, socio-economic and demographic factors. Materials and Methods: This study was carried out in 208 people (patients-104, controls-104) from January 2012 to September 2013 using a structured questionnaire containing details of lung cancer risk factors including smoking, secondhand smoke, tobacco leaf intake, age, gender, family history, chronic lung diseases, radiotherapy in the chest area, diet, obesity, physical activity, alcohol consumption, occupation, education, and income. Descriptive statistics and testing of hypotheses were used for the analysis using SPSS software (version 20). Results: According to this study, lung cancer was more prevalent in males than females. Smoking was the highest risk factor (OR=9.707; RR=3.924; sensitivity=0.8872 and P<0.0001) followed by previous lung disease (asthma, tuberculosis etc.) (OR=7.095; RR=1.508; sensitivity=0.316 and P<0.0001)) for male patients. Highly cooked food (OR=2.485; RR=1.126; sensitivity=0.418 and P=0.004)) and also genetic inheritance (OR=1.93; RR=1.335; sensitivity=0.163 and P=0.138) demonstrated significant correlation with lung cancer as risk factors after these two and alcohol consumption was not prevalent. On the other hand, for female patients, tobacco leaf intake represented the highest risk (OR=2.00; RR=1.429; sensitivity= 0.667 and P=0.5603) while genetic inheritance and highly cooked food also correlate with lung cancer but not so significantly. Socioeconomic status and education level also play important roles in causing lung cancer. Some 78.5% male and 83.3% of female cancer patients were rural residents, while 58.2% lived at the margin or below the poverty line. Most male (39.8%) and female (50.0%) patients had completed only primary level education, and 27.6% male and 33.3% female patients were illiterate. Smoking was found to be more prevalent among the less educated persons. Conclusions: The results obtained in this study indicate the importance of creating awareness about lung cancer risk factors among Bangladeshi people and making appropriate access to health services for the illiterate, poor, rural people.
Purpose: This study was conducted to explore relationships of postpartum depression with socio-demographic and clinical characteristics of preterm infants and mothers. Methods: Participants were the mothers of 80 premature infants admitted to neonatal intensive care units. Postpartum depression was measured using the Edinburg Postnatal Depression Scale (EPDS). Clinical characteristics were examined through the medical records. The physiological state for the infants was evaluated using the revised Neurobiologic Risk Score (NBRS). Data were analyzed using the t-test, ANOVA, and Pearson correlation coefficients. Results: Average for EPDS was $9.75{\pm}5.06$, and 30% of the participants were at high risk for postpartum depression. There were significant differences in postpartum depression according to mother's education level (F=3.493, p=.035), economic state (F=5.828, p=.004), multiple pregnancy (t=2.141, p=.037), chorioamnionitis (t=2.349, p=.021), oligohydramnios (t=-2.226, p=.029), broncho-pulmonary dysplasia (t=2.085, p=.040), germinal matrix hemorrhage (t=2.259, p=.027), and revised NBRS (t=-2.772, p=.007). There was a significant positive correlation between postpartum depression and number of health problem of infants (r=.252, p=.024) and revised NBRS (r=.316, p=.004). Conclusion: As 30% of the mothers with preterm infants were at high risk for postpartum depression, they require attention. When providing interventions, socioeconomic status as well as the physiological state of premature infants should be considered.
This research aims to investigate the socio-demographic, financial, and housing statuses of young married couples in Chonsei housing and to analyze the determinants of their residential environment quality and housing expenditure in four districts - Seoul and Gyeonggi-Incheon Area(GIA) of the Seoul Metropolitan Area(SMA), and metropolises and non-metropolises of non-SMA. From the 2020 Korean Housing Survey(KHS), this cross-sectional analysis examined a sample of 691 households, and the findings revealed that most were headed by college-educated, salaried male workers aged 31 years old. While childless dual-earner couples were common in Seoul, single-income families of three were prevalent in non-SMA. The financial status of the couples in Seoul was a lot better than in the other three areas, particularly much higher in Chonsei deposit and total asset value. Further, many lived in a three-bedroom apartment unit sized 60m2 and bigger, using a Chonsei loan. Regardless of areas, almost all the households spent a very low portion of their living expenses and income on housing costs. However, dual-earner families positively increased borrowing capacity, which improves the household's financial position that is likely to lead to equity increment in a volatile asset market in the long run. The statistical results indicated that residential environment assessment was influenced by neighborhood quality and housing expenditure was affected by housing size in Seoul, urban amenities in GIA and householder's gender in non-metropolises. Thus, this research proposes that strong measures be considered to mitigate housing inequality embedded in geographical and socio-economic disparities.
The aim of this study was to examine the spouse effects on depressive symptom and suicidal thinking among the elderly aged 65 and over in Korea. The subjects selected from the database of the Fourth Korea National Health and Nutrition Examination Survey(KNHANES IV) conducted by Korea Centers for Disease Control and Prevention from 2007 to 2009. Those who were female, older, lower educated, or poorer were more likely to live alone than their counterparts respectively. The elderly living alone experienced depressive symptom as 2.0 times(OR=2.004, 95% CI=1.433, 2.803) as, and suicidal thinking as 1.6 times(OR=1.567, 95% CI=1.111, 2.211) as the elderly couples did, adjusting for socio-economic factor, health status factors, and health behaviors factors. As for the male subgroup, the elderly living alone experienced depressive symptom as 4.0 times(OR=3.997, 95% CI=2.066, 7.732) as, and suicidal thinking as 3.2 times(OR=3.181, 95% CI=1.535, 6.592) as the elderly couples did. On the other hands, there was no significant difference in depressive symptoms and suicidal thinking between the female elderly living alone and couples. The authors suggested policy interventions to promote the mental health of the male elderly living alone.

Background: Breast cancer is the most common cancer in women worldwide. Although different metabolic factors have been implicated in breast cancer development, the relationship between hypertension and breast cancer has not been elucidated. Aim: To evaluate hypertension as a risk factor for breast cancer in Chilean women of low and middle socio-economic status. Methods: We conducted an age-matched (1:1) case-control study in 3 hospitals in Santiago, Chile. Breast cancer cases (n=170) were histopathologically confirmed. Controls had been classified as Breast Imaging Reporting and Data System I (negative) or II (benign findings) within 6 months of recruitment. Blood pressure was measured using a mercury sphygmomanometer and standardized procedures. We used 2 hypertension cut-off points: blood pressures of ${\geq}140/90$ mmHg and ${\geq}130/85$ mmHg. Fasting insulin and glucose levels were assessed, and anthropometric, sociodemographic, and behavioral information were collected. Odds ratios and 95% confidence intervals were estimated for the entire sample and restricted to postmenopausal women using multivariable conditional logistic regression models. Results: Hypertension (${\geq}140/90$ mmHg) was significantly higher in cases (37.1%) than controls (17.1%) for the entire sample and in postmenopausal pairs (44.0% compared to 23.8%). In crude and adjusted models, hypertensive women had a 4-fold increased risk of breast cancer (adjusted odds ratio: 4.2; 95% confidence interval: 1.8; 9.6) compared to non-hypertensive women in the entire sample. We found a similar association in the postmenopausal group (adjusted odds ratio: 2.8; 95% confidence interval: 1.1; 7.4). A significant effect was also observed when hypertension was defined as blood pressure of ${\geq}130/85$ mmHg. Conclusion: A significant association was found between hypertension and breast cancer over the entire sample and when restricted to postmenopausal women. Hypertension is highly prevalent in Latin America and may be a modifiable risk factor for breast cancer; therefore, a small association between hypertension and breast cancer may have broad implications.
