Objectives : This study was performed to examine the influence of smoking on the blood cadmium concentration in university students. Methods : The study included 300 university students. A questionnaire interview was used to collect data. The urine cotinine and blood cadmium levels were measured as biological exposure indices. The data were analyzed using t-tests ANOVA and ANCOVA. Results : The median value of blood cadmium concentration was equal in both males and females ($0.8{\mu}g/l$). This level was relatively low in comparison with the reference value suggested by WHO (2001). ANCOVA showed that smoking related variables, urine cotinine and smoking amount, were significantly associated with the blood cadmium level (P=0.004, 0.015). However, the values with regard to traffic related air pollution were not significantly associated with the blood cadmium level. Conclusions : Smoking is an important source of nonoccupational cadmium exposure in young people. The Blood cadmium level is at least 10% higher in active smokers than in passive or nonsmokers. The level of urine cotinine can be used as an indicator of non-occupational exposure of respirable cadmium due to smoking, as there is a good correlation bestween smoking amount and the urine cotinine level.

Objectives: Thirdhand smoke (THS) refers to residual tobacco smoke pollutants that remain after cigarette smoking. The purpose of this study was to determine predictors of the belief among adults in Korea that THS is harmful to children. Methods: A population-based sample of 3,000 adults (${\geq}19$ years) among a web-based panel in Korea was obtained in November 2016. The respondents filled out questionnaires, including THS beliefs, smoking status, presence of voluntary smoke-free rules at home, and support for the implementation of smoke-free regulations at home. THS beliefs were assessed with a statement that staying in a room today where people smoked yesterday can harm the health of children. Results: Overall, 92.2 % of adults believed that THS exposure could harm the health of children. Respondents who were nonsmokers, believed that SHS exposure were associated with pneumonia of children, lived in home with complete smoke-free rule at home, and supported the implementation of smoke-free regulation at home were more likely to believe that THS could harm for health of children. Conclusions: The majority of Korean adults believed that THS exposure could harm the health of children. Predictors identified in the study can be useful to address the risk of THS beliefs and promote implementation of tobacco control policies.

Objective : To examine the relationship between cigarette smoking, alcohol and cancer mortality in men in the Kangwha cohort after 12 years and 10 months of follow up. Methods : The subjects consisted of 2,681 men in the Kangwha cohort aged over 55 in 1985. Number of deaths and the time to death front all cancers and other cause were measured and the data for the smoking and drinking habits were obtained from the baseline survey data in 1985. All subjects were categorized into four groups according to their smoking habits: non-smokers, ex-smokers, mode(ate-smokers (1-19 cigarettes per day), heavy-smokers ($\geq$20 cigarettes per day). In addition, they were also categorized according to their drinking habits: non-drinkers, light-drinkers ($\leq$1 drink per week), moderate-drinkers (<3 drinks per day), heavy-drinkers ($\geq$3 drinks per day). The cancer specific death rates were calculated according to their smoking and drinking status. The adjusted risk ratio for all cancer deaths according to their smoking and drinking status were estimated using the Cox's proportional hazard regression model. Results : Using nonsmokers as the reference category, the adjusted risk ratio for all cancer deaths were 1.573(95% CI=1.003-2.468) for heavy-smokers. For lung cancer deaths, the adjusted risk ratios were 3.540(95% CI=1.251-10.018) for moderate-smoker and 4.114(95% CI=1.275-13.271) for heavy-smokers. Compared to non-drinkers, the adjusted risk ratio for stomach cancer was 2.204(95% CI=1.114-4.361) for light-drinkers. Conclusion : Smoking is the most significant risk factor for cancer deaths particularly lung cancer.

Through various media, damage of both smoking and second-hand smoking has been recognized, and brought global scale of interest in antismoking. In Korea, government has tightened regulations of smoking in non-smoking zone since December, 1980, and after National Health Promotion Act in 1995, non-smoking zone has been gradually expanded. On the other hand, there were law suits to find those regulation towards smokers are either unconstitutional or not for 4 times. In this current state, people need smoking area to prevent second-hand smoking and to consider smokers in multi-unit dwelling. Main purpose of this research is to plan smoking spaces based on various typology of multi-dwelling plan for protection of both smokers and non-smokers' right. The research group collected and analyzed the smoking behaviors in various multi-unit dwelling types such as flat type, tower type, hybrid type and others. Based on those data, the group found three phenomena. First, there are internal regulations in multi-unit dwelling to make non-smoking zone based on National Health Promotion Act and resident representative meeting decision. Second, main smoking activities are occurring at major traffic line and entrances. Third, smoking inside of multi-unit dwelling complex causes second-hand smoking to residents live in $1^{st}$ floor and when they enter. Therefore, one can achieve both smokers' and non-smokers' protection of right by creating a designated smoking space near main entrances of multi-unit dwelling complex to consider smokers' and prevents second-hand smoking by using shaft space, which is in core space, to ventilate tobacco smoke through roof.

Background: Despite the high life expectancy, the subjective health status of the elderly people in Korea is reported to be the lowest as compared to other age groups. The purpose of the conducted study was to identify the factors related to the subjective health status of elderly people aged over 65 in Korea. Methods: This study used data from the 7th Korea National Health and Nutrition Examination Survey (2016-2017) of the Korea Disease Control and Prevention Agency. The subjects of the study were selected to be 2,904 elderly people aged over 65. The factors that were selected related to subjective health status were socio-demographics, perceived diseases, health behaviors, and mental health. Results: As a result of the examination of the subjective health status according to the characteristics of the subjects of study, the subjective health status was high in males (β=0.144, p=0.011), urban dwellers (β=0.107, p=0.015), employed persons (β=0.139, p=0.001), college graduates (β=0.322, p<0.001), persons with high household income (β=0.226, p<0.001), persons without chronic disease, nonsmokers (β=0.146, p=0.009), drinkers (β=0.111, p=0.003), persons who practiced aerobic physical activity (β=0.150, p<0.001), persons without depression (β=0.286, p<0.001), and persons who rarely had stress (β=0.837, p<0.001). Conclusion: More attention should be paid to those with low subjective health to improve health for elderly people. Expanding policy supports are required for elderly people with low socioeconomic status, chronic disease or depression, or unhealthy behaviors (smoking or lack of physical activity).

Purpose: This study investigated the differences in physical function, self-efficacy (SE), and health-related quality of life (HRQoL) categorized by disease severity in community-dwelling patients with chronic obstructive pulmonary disease (COPD). Methods: This cross-sectional study included 182 patients with COPD selected from the pulmonology outpatient department of a tertiary hospital. Disease severity was measured using forced expiratory volume in 1 second (FEV1). Physical function, SE, and HRQoL were measured with the six-minute walking distance, Pulmonary Rehabilitation Adapted Index of Self-Efficacy (PRAISE), and St. George's Respiratory Questionnaire (SGRQ). Disease duration, FEV1, and 12-month history of exacerbations were obtained from medical records. Patients were categorized by Global Initiative for Chronic Obstructive Lung Disease (GOLD) category. Data were analyzed using the χ² test, and one-way ANOVA. Results: Most of the participants were male and nonsmokers. The disease duration was 10.76 ± 10.03 years, the mean FEV1% was 62.13 ± 22.80, and 70.3% of the participants were in GOLD category 2 (moderate) or milder. Half of the participants reported modified Medical Research Council scores ≥ 2. Patients in GOLD categories 1 and 3 (mild and severe) exhibited significantly higher PRAISE scores than those in the other groups (F = 8.23, p < .001). The total SGRQ scores were highest in GOLD 4 (very severe), indicating the lowest HRQoL. Significant differences were identified among GOLD 1, GOLD 2 and 3, and GOLD 4 (F = 9.92, p < .001). Conclusion: We identified potentially useful variables to comprehensively assess disease severity and tailor management strategies, including airflow limitation, and to determine the consequences of COPD from patients' perspectives.

This study was performed to investigate the effect of the health related factors on the preference and frequency of intake of coffee and traditional beverages among 280 university students (128 males and 152 females) who were residing in Incheon areas. The results were as follows; 1. Male students of over weight and obese were more than female students and female students of under weight were more than male students. Female students were interested in weight control and had an experience in weight control more than male students. 2. The group who was much interested in weight control preferred green tea, yuja tea and dunggulre tea. The group who was much interested in health when drink beverages preferred green tea, ginseng tea, dunggulre tea, vinegar drinks and water but didn’t prefer coffee. 3. The frequency of intake of green tea is high in the group who had an experience in weight control. And the frequency of intake of honey tea was high in the group who drank alcohol almost every day. Coffee intake was the highest among beverages in smokers and water intake was the highest among beverages in nonsmokers. In conclusion this study showed that as an interest in health is higher, the preference and frequency of intake of coffee was low whereas those who intake of traditional beverages was high in general.
