Workload assessment is one of the important elements of the human factors evaluation for the nuclear power plants in operation. This paper describes a further study upon the additional elements of the workload which elements should be considered in the subjective workload assessment. We have tried to predict the burden of the work and to improve the work through a comparison of the objective workload and the subjective workload in the previous studies in nuclear power plants. However, there is a restriction to perform a precise assessment because of the limitations of the method itself. The objective workload assessment is performed by relative comparison using the quadrant analysis with objective workload and subjective workload because there were no clear criteria of objective workload assessment. And the subjective workload assessment is performed by NASA-TLX (NASA Task Load Index) which includes six evaluation dimensions of subjective workload. NASA-TLX is difficult to grasp the other aspects that could influence on the subjective workload because the analysis relies on predetermined assessment items. We conduct a factor analysis between the factors that affect the workload and the assessment adopted from ISO 10075 and NASA-TLX. At the same time, this study suggests other evaluation elements which can be added for subjective workload assessment except for evaluation elements of NASA-TLX.

Background: This study was aimed at investigating the type of work of dental hygienists and identifying factors affecting the subjective health status according to hazardous risk factors in the working environment. Methods: From May 15 to 31, 2019, we surveyed 411 dental hygienists working at dental hospitals in the metropolitan area. SPSS 25.0 was used to perform the frequency analysis, t-test, one-way analysis of variance, Pearson's correlation analysis, and multiple regression analysis. Results: Regarding factors related to the degree of exposure to hazardous risk factors in the work environment and subjective health status, the more exposed the ergonomic (p<0.05) and psychological (p< 0.001)factors, the worse is the subjective health status. Conclusion: The results of this study suggest that the working environment should be improved for dental hygienists such that they can perform their duties in a safe environment.

Purpose: This study investigated the trajectory of subjective health status in married postmenopausal women and aimed to identify predictive factors affecting subjective health status. Methods: Data were obtained from women who participated in wave 4 (2012) of the Korean Longitudinal Survey of Women & Families Longitudinal Study and continued to the latest phase (wave 7, 2018). A latent growth model (LGM) was used to analyze data from 1,719 married postmenopausal women in the framework of the ecological system theory. Results: The mean age of the participants at wave 4 was 56.39±4.71 years, and the average subjective health status was around the midpoint (3.19±0.84). LGM analysis confirmed that subjective health status decreased over time (initial B=3.21, slope B=-0.03). The factors affecting initial subjective health were age, body mass index, frequency of vigorous physical activity (microsystem level), marital satisfaction (mesosystem level), and medical service utilization (macrosystem level). Medical service utilization and the frequency of vigorous physical activity were identified as predictive factors affecting the slope in subjective health status. The model fit was satisfactory (TLI=.92, CFI=.95, and RMSEA=.04). Conclusion: This analysis of the trajectory of subjective health status of married postmenopausal women over time confirmed that subjective health is influenced by overall ecological system factors, including the microsystem, mesosystem, exosystem, macrosystem, and chronosystem. Therefore, it is necessary to assess physical activity and support policies promoting access to medical services in order to improve the subjective health status of married postmenopausal women.

This study was conducted to identify factors that affect subjective health in middle-aged with hypertension. Hypertension, a representative chronic disease, is a disease of increasing prevalence from middle age. To effectively manage hypertension from middle age, it is necessary to revise lifestyle based on subjective health awareness. The subjects of this study were 2,254 middle-age with hypertension who were 30-64 years of age among the 2014-17 national health and nutrition survey. Study variables consisted of general, physical, and psychological factors. For data analysis, compound statistics were made using SPSS 25.0 program and then complex statistics. The results of this study showed that the factors that significantly influenced the subjective health of the subjects were sex, age, economic level, number of households, home ownership, stress, quality of life, and their explanatory power was 20.4% (F = 12.58, p<.001). The results of this study can be used as a basis for the intervention to improve the subjective health of middle-aged with hypertension. Appropriate lifestyle modifications are needed to effectively manage hypertension based on good subjective health awareness.

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.

Objectives: The purpose of this study was to investigate the relationship between demographic characteristics, health factors, oral health factors and subjective body shape perception of adolescents in order to provide basic data for adolescents health management. Methods: This study was analyzed using Korea Youth Risk Behavior Web-Based Survey in 2015, where 68,043 adolescents in total participated. Data were analyzed by SPSS Ver. 21.0. Multiple regression analysis was used to analyze the relationships among health factors and oral health factors related to subjective body shape perception. Results: The analysis of the factors influencing the body shape perception of male adolescents showed that they tend to be low in school performance, low in family economic level, and high school students. The worse they perceive their subjective health to be, the more they feel stress, and the less frequently they brush their teeth per day. They had bad breath. The analysis of the factors influencing the body shape perception of female adolescents showed that they tend to be low in school performance, low in family economic level, and high school students. The worse they feel their subjective health is, the more they feel unhappy, and stressful, and the less frequently they brush their teeth per day. They feel pain during chewing, and have bad breath. Conclusions: In conclusion, it is necessary to consider educational intervention in adolescent life that will make them have proper perception of their body shape for proper health management of it. To make the intervention effective, we need to consider various factors such as health factors and oral health factors.

Purpose: This study examined the factors that affect suicidal ideation among Korean adolescents according to their family type. Methods: The data of the 2017 Korea Youth Risk Behavior Web-based Survey was used in this study. Out of 62,276, a total of 60,077 adolescents (51,367 adolescents from two-parent families and 8,710 adolescents from single-parent families) were included in the analysis. Results: This study demonstrated that the level of suicidal ideation of the adolescents in single-parent families was significantly higher than that of the adolescents in two-parent families. The factors that affect suicidal ideation among the two-parent family adolescents were gender, grade, economic status, academic performance, smoking, drinking, physical activity, subjective health status, subjective body image, subjective happiness, stress, and depression. The factors that affect suicidal ideation among the single-parent family adolescents included gender, grade, smoking, subjective health status, subjective happiness, stress and depression. Conclusion: Single-parent family adolescents are likely to have a higher level of suicidal ideation along with higher levels of depression and stress and lower levels of subjective health and happiness, compared to single-parent family adolescents. For this higher-risk group of suicidal ideation, more thoughtful attentions and proactive policies are needed to manage their mental health and stress in school and family situations.
