The purpose of this study was to investigate differences in longevity factors for 3 age groups: centenarians, octogenarians, and sexagenarians. There were 389 elderly Korean subjects who participated in this study. This included 109 centenarians who participated in the 1-wave study that examined the longevity factors using the health behaviors and psychological reactions. The study that examined the longevity factors by using odds ratio of the logistic regression analysis. The major findings indicate that female centenarians and octogenarians scored the highest in abstinence from alcoholic drinking than males from these same 2 age groups (OR=9.04, CI=4.04, 20.24). Centenarians scored higher in non-visiting hospitals (OR=11.48, CI=5.56, 23.70) and showed little emotion when watching sad scenes, upon comparison with the younger 2 age groups. Also, centenarians scored higher in laughter (OR=11.59, CI=5.04, 26.63), showing no anxiety (OR=12.49, CI=6.42, 24.32), and displaying indifference towards games, when compared with the younger 2 age groups. The findings imply that Korean centenarian leads to a life of longevity is the result not only of psychological reactions but also of health behaviors. Also, these results support future studies of improvement of longevity factors.

We investigated the occurrence of color vision loss in 70 organic solvent mixtures exposed workers and in 47 controls. Color Vision was assessed with a color arrangement test designed to identify the defective color sense, the Han Double 15-Hue Test. The results of the test were no significant difference between exposed workers and controls in the proportion of subjects who committed one or two errors. Quantitative analysis, using color confusion index(CCI), showed no signicant difference between exposed workers and controls. A significant linear correlation was present between age and CCI in both exposed workers (CCI=0.0056age + 0.94; r=0.23; p<0.05) and controls(CCI=0.0066age + 0.86; r=0.33; p<0.05). Qualitative analysis of the patterns on the hue circle showed that the prevalence of acquired dyschromatopsia was 21% in both and no significant difference. Multiple regression analyses showed that age was significantly related to color vision loss. These results did not provide evidence of a relationship between organic solvents exposure and incidence of color vision loss. In field studies for monitor the people at risk of the acquired color vision loss involving low-dose organic solvents exposed workers, both quantitative and qualitative information should be considered.

This study compared the individual, family, environmental factors, and subjective sleep sufficiency according to gender among Korean adolescents and to examine relevance among the individual, family, environmental factors, and subjective sleep sufficiency. The subjects were 65,528 Korean adolescents(male: 33,803, female: 31,725), who were derived from the 12th Korea Youth Risk Behavior Web-based Survey 2016 in South Korea. As a result, the prevalence of the subjective sleep sufficiency in this study was 33.4% male and 19.5% female. The subjective sleep sufficiency was affected by the depression experience, suicidal ideation, school achievement, feeling of stress, feeling of happiness, subjective health status, alcohol experience, smoking experience, substance experience, allergic rhinitis, and atopic dermatitis in individual factors; economic status, educational level of parents and living arrangement in family factors; school grade, school type and emotional support in environmental factors in both males and females. In individual factors, breakfast eating and asthma affected the male's subjective sleep sufficiency and physical activity affected the female's. The mental health of the individual factors was the most influential factor in adolescent's subjective sleep sufficiency. Therefore, nursing intervention to improve Korean adolescent's subjective sleep sufficiency should be applied considering gender differences.

Purpose: In this study, eye-health inequity was investigated by analyzing the relationship between household incomes and eye-health of senior citizens. Further, this study suggested the preliminary data for establishment of public eye-health policy in order to improve low income senior citizens' life quality. Methods: The data from the 2009 Survey of Korea National Health and Nutrition Examination were analyzed in this study. The objectives of the KNHNE survey were over 65 year old group (1,668 people). Main factors of eye-health (visual acuity, cataract, pterygium, intraocular pressure, retinophathy, age-related macular degeneration, diabetic retinophathy, myopia, hyperopia, astigmatism, and anisometropia prevalence) were analyzed with t-test and chi square test. Results: Low income group revealed that refractive error rate and intraocular pressure were low, however, naked eye visual acuity and corrected visual acuity were high at 0.1 to less than 0.5. On the other hands, in the high income group, there was high prevalence of hyperopia. Cataract mainly occurred at low income group besides group which maximum corrected visual acuity was below 0.8 also highly showed cataract. Moreover, the prevalence of cataract showed that it related with smoking, drinking, occupation, and education level. Conclusions: Results revealed that there was inequity of eye-health which related with socioeconomic status of the elderly. Especially, the prevalence of cataract was correlated with life quality. Consequently, establishment of public eye-health policy seems to be required for eye-health inequity of low income senior citizens.

In this study, the impact of the emotional labor on the job satisfaction according to the service characteristics and the patient type was investigated in the 269 dental hygienist. The average score of the emotional labor according to the general characteristics was 2.85 and it was higher in case of the male and in case of the drinkers. The average score of the job satisfaction according to the general characteristics was 3.02 and the female was higher than the male, the older professionals than the younger professionals and the married was higher than the singles. In the emotional labor according to the service characteristics, the dental hygienist was highest than the other professionals and in the job satisfaction according to the service characteristics, it was higher the higher the career and the higher the income. In the emotional labor by patient type, it was highest when the patient was male, when ages were between 20 and 64, and when it was after 7 PM. The job satisfaction by patient type was higher when the patient age was 65 years old or older, when the type of treatment was dental caries and periodontal diseases, when the consultation hour was after 7 PM and when the economic level of patient was high. The job satisfaction was increased when the emotional labor was 'average' but was analyzed as the lowest when the emotional labor was high. A hierarchical regression analysis was conducted to examine the effects of work characteristics, patient type, and emotional labor on job satisfaction(t = 1.994, p = .047), which had high monthly incomes Patients with older patients (t = 3.027, p = .003), the lower the emotional labor (t = 13.858, p = .000), the higher the job satisfaction. That is, to increase the job satisfaction of the dental health professionals, the effort to make the pleasant working environment should be made considering the emotional labor or the characteristics of patient.

This study was conducted to determine the association between quality of sleep (QOL) and the general characteristics, the health-behavioral factors, and the occupational characteristics of firefighting officers. The survey was conducted in October 2016 with a self-administered questionnaire using the Pittsburgh Sleep Quality Index (PSQI) developed by Pittsburgh University, targeting 600 male firefighting officers working at five fire stations in D city. As a result, the QOL of the study subjects measured by the PSQI revealed 13.2% to be good, and 86.8% to be poor. In relation to general characteristics and health habits, the rate of the group who had poor quality sleep was significantly higher in those with a lower subjective health status, in the non-smoking group, and in the low sleep-quality group, compared to the good sleep-quality group. For occupational characteristics, the rate of those with poor quality sleep was significantly higher in groups such as the fire suppression group, the shift work group, the hard physical labor group, the group with a lower sense of satisfaction in their work, and in the group classed as unfit for the job but who were not considering quitting their jobs, compared to their respective counterparts. Multiple regression analysis revealed factors of influence with explanatory powers of 24.4% for subjective health status, alcohol use, subjective quality of sleep, career, job position, and physical labor. The results of this study suggest that the quality of sleep for firefighting officers is significantly related to general characteristics, health-behavioral characteristics, and occupational characteristics.
