Consumers' interest in health is increasing, and health-seeking consumption lifestyles, including comprehensive consumption behaviors related to physical health, mental health, and a healthy dietary lifestyle are becoming increasingly important to many people. The purpose of this study was to develop a health-seeking consumption lifestyle scale that could aid in determining effects of social status, perceived health status, and socio-demographical variables on health-seeking consumption lifestyles. Data were collected via an on-line survey of 500 respondents, all of whom were married women 20 year of age or older. The data were analyzed in terms of frequency, percentage, mean, standard deviation, factor analysis, t-test, one-way ANOVA, Pearson's correlation analysis, and multiple regression analysis. The results of this study are as following: First, health-seeking consumption lifestyle demonstrated three main factors: physical health-seeking consumption lifestyle, mental health-seeking consumption lifestyle and healthy dietary life seeking consumption lifestyle. Second, most respondents identified themselves with the middle class and perceived their health status positively. Third, health-seeking consumption lifestyle demonstrated significant differences based on socio-demographical variables. Fourth, health-seeking consumption lifestyle was significantly affected by social class, age, and health status comparisons within similar age groups.

Formaldehyde is important because of their irritant and toxic properties, mutagenicity and carcinogenicity. In this study, liquid chromatography-mass spectrometry (LC-MS) is used for the analysis of formaldehyde after derivatization with 2,4-dinitrophenylhydrazine (DNPH) cartridge. Analytical parameters such as linearity, repeatability and minimum detection limit were evaluated. The linearity ($r^2$) was 0.9997 when analyte concentration ranges from 25 to $200{\mu}g/l$. The relative standard deviation (%RSD) was 1.25 % for concentration of $200{\mu}g/l$. The minimum detection limit (MDL) was 0.73 ppbv. It was shown that LC-MS method has a great potential for formaldehyde analysis. The results of formaldehyde from the survey of Ban-Woll and Shi-Hwa Industrial Complex samples, the highest level was 6.20, 3.93 ppb, respectively. The highest emission level of formaldehyde at chemical plants in the Ban-Woll' Shi-Hwa Industrial Complex was 5421.25 ppb.

Background: Numbers of epidemiological studies assessing residential radon exposure and risk of lung cancer have yielded inconsistent results. Methods: We therefore performed a meta-analysis of relevant published case-control studies searched in the PubMed database through July 2011 to examine the association. The combined odds ratio (OR) were calculated using fixed- or random-effects models. Subgroup and dose-response analyses were also performed. Results: We identified 22 case-control studies of residential radon and lung cancer risk involving 13,380 cases and 21,102 controls. The combined OR of lung cancer for the highest with the lowest exposure was 1.29 (95% CI 1.10-1.51). Dose-response analysis showed that every 100 Bq/$m^3$ increment in residential radon exposure was associated with a significant 7% increase in lung cancer risk. Subgroup analysis displayed a more pronounced association in the studies conducted in Europe. Studies restricted to female or non-smokers demonstrated weakened associations between exposure and lung cancer. Conclusions: This meta-analysis provides new evidence supporting the conclusion that residential exposure to radon can significantly increase the risk of lung cancer in a dose-response manner.

There are many reservoirs used as the source of water supply and they show various specific characteristics in water quality depend seasonal. Especially, there were not a little variations of water quality in summer, as a natural consequence it follows that stratification occured phenomenon and changed anaerobic condition in the bottom of reservoir, and then accumulated Fe and Mn substance in soil and sediment were resolved into water, it attributes to coloration. G purification plant located in Y gun is very small plant in which coloration occurs by Fe and Mn in every summer. Using this plant as a model, the removal methods of Fe and Mn were studied. After prechlorination plus LAS coagulation, Fe, Mn, $NH_3-N$ were decreased from 7.290 mg/l to 0.080 mg/l, from 0.480 mg/l to 0.075 mg/l, from 0.55 mg/l to 0.04 mg/l. But $THM_{s}$ was increased from 0.050 mg/l to 0.044 mg/l. It shows that the prechlorination plus LAS coagulation treatment process in purification plant is effective to remove Fe and Mn ion.

Purpose: This study explored the factors influencing the health-related life satisfaction of people with disabilities who engaged in physical activity, by age and gender. Methods: A secondary analysis was conducted of the 2020 Third Disability and Life Dynamics Panel (2021). The participants were 2,796 people who performed regular physical activity at least once a week. The variables selected were disability-related factors (degree of disability, multiple disabilities, and type of disability), sociodemographic factors (age, gender, living alone, and mean monthly family income), and health-related factors (amount of physical activity, self-esteem, depression, chronic disease, subjective health, and health-related life satisfaction). Descriptive statistics, the chi-square test, the t-test, two-way analysis of variance, and multiple regression analysis were conducted. Results: In total, 58.0% of participants were male, and 42.0% were female. For age groups, 14.4% were children/adolescents (0-19 years), 42.6% were adults (20-59 years), and 43.0% were seniors (≥60 years). The mean score for health-related life satisfaction was 5.0±2.15 out of 10. Adults and seniors whose level of physical activity met or exceeded recommendations had higher subjective health. Moreover, men had better subjective health than women in seniors. Health-related life satisfaction was higher among those who had higher self-esteem, were not depressed, did not have chronic diseases, and had better subjective health. Conclusion: Gender significantly influenced health-related life satisfaction in children/ adolescents and seniors. Disability-related factors were significant in adults, and health-related factors were significant in all age groups. Therefore, these factors should be considered when designing interventions to promote subjective health and health-related life satisfaction of people with disabilities.

Background: The purpose of this study is to analyze whether there is a change in patterns of medical use among those likely to be converted their health insurance qualifications when the family support rule is alleviated. There is no empirical analysis that converting health insurance qualification will affect the increase in medical use. Methods: For analysis, data were extracted from the national health insurance eligibility and medical care database. To identify analysis targets similar to that of medical aids' characteristics among health insurance coverage, we compared income, property level, and medical use patterns through basic statistical analysis and used a difference-in-difference (DID) analysis to estimate the net effect of changes in medical use following the change of qualifications. Results: The main results are as follows. The results show that those who are under the 5% income group (1st income group) of health insurance coverage are the most similar to the medical aids group. DID analysis shows that changes in the medical use of people who maintain their national insurance qualification and who are not. As a results, the number of hospitalized days of converting group was reduced by 3.5 days while outpatient days were increased by 1.8 days. Conclusion: As a result, there was not much difference in the patterns of medical use for the under 5% income group who are likely to be eligible for expanded medical aids when the family support rule is alleviated. In addition, more than 30% of them are in arrears with their health insurance premiums, causing inconvenience in using medical services. These findings suggest the need of abolishing the criteria obligated to support family, and great efforts should be made to contribute to non-paid poor and remove their medical blind spot.
