Depression is a disease with an increasing prevalence worldwide, and is highly associated with mortality as well as several diseases such as hypertension. The aim of this study is to discover clinical risk indicators associated with depression in the occupational group of simple labor workers. This study used the Seventh Korean National Health and Nutrition Examination Survey (2016-2018) conducted by the Korea Centers for Disease Control and Prevention. In association between depression and demographic information, age, sex, degree of stress perception, and stress perception ratio indices had a very high statistical association with depression, and education level and marital status were also associated with depression. Obesity indices such as abdominal circumference and body mass index were not associated with depression. Among the blood information, hemoglobin and hematocrit were highly associated with depression, and statistical significance was maintained even in the analysis adjusted for sex and age. The results of this study can be used as information for the prevention and treatment of depression in the occupational group of simple labor workers in the future.

Critical nitrogen concentration (Nc), which is defined as the minimum % N in shoots required to maintain the maximum growth rate of top dry weight (W) at any time, was determined for rice plant. Using two rice varietal groups, japonica varieties and an indica $\times$ japonica "Dasanbyeo", 18 data points fulfilling the statistical criteria for determining Nc were obtained through eight N-fertilization experiments over two years at Suwon (37$^{\circ}$16'N), Korea. Nc dilution curve for each variety was obtained by fitting the Nc-W relationship to power function. However, The critical nitrogen curves for the two variety groups were not different statistically. Thus, a Nc dilution curve was fitted for the Nc data points pooled over the two variety groups and proposed in rice as: Nc=4.08, where W＜1.73 t h $a^{-1}$ , Nc=5.197 $W^{0.425}$3/ ($R^2$=0.964), where 1.73 t h $a^{-1}$ ＜W＜12 t h $a^{-l}$. The Nc for W＜1.73 t h $a^{-l}$ were estimated as a constant value of 4.08%, the mean value of the maximum N concentration for N-limiting condition and the minimum N concentration for N non-limiting condition. The model for Nc is applicable to diagnosing the nitrogen nutrition status during the rice growth period from emergence to heading stage. The Nc curve well discriminated the 144 data points between the N limiting and the N non-limiting groups regardless of varieties, cultural methods, and years.-limiting groups regardless of varieties, cultural methods, and years.

Recently, wellness has become an issue related to improvements in personal health and quality of life. Data that are accumulated daily, such as meals and momentum records, in addition to body measurement information such as body weight, BMI and blood pressure have been used to analyze the personal health data of an individual. Therefore, it has become possible to prevent potential disease and to analyze dietary or exercise patterns. In terms of food and nutrition, analyses are performed to evaluate the health status of an individual using dietary data. However, it is very difficult to process the large amount of dietary data. An analysis of dietary data includes four steps, and each step contains a series of iterative tasks that are executed over a long time. This paper proposes a problem solving environment that automates dietary data analysis, and the proposed framework increases the speed with which an experiment can be conducted.

Background: Sarcopenia is a skeletal muscle disorder that involves the loss of muscle mass and function. Handgrip strength (HGS) is the most commonly used tool to assess muscle strength to diagnose sarcopenia. HGS is also associated with various diseases and health outcomes. Thus, we aimed this study to examine the HGS status in Korean adults and relevant factors of HGS. Methods: Data was obtained from the 7th Korea National Health and Nutrition Examination Survey (KNHANES), a population-based nationwide survey. The estimated mean value of HGS was calculated in each age group. The mean HGS in men and women aged over 40 was compared according to the household income level, lifestyle factors, and comorbidities. Results: A total of 16,708 participants were included in this study. The mean HGS showed a maximum value in the 30s for both men and women, and then tended to decrease with increasing age. When analyzed for people aged 40 or older, the mean HGS was significantly higher in the current or past smoker, drinker, and aerobic exercise groups in both men and women. The mean HGS was lower in the group with comorbidities such as hypertension, dyslipidemia, type 2 diabetes, and bone diseases. Conclusion: Our study found that the mean HGS was significantly different between those with and without underlying chronic diseases. In groups with relevant comorbidities, close monitoring for the development of sarcopenia and taking preventive measures such as exercise and nutritional support may be recommended.

Background: Several studies have revealed the frequency of family mealtimes to be inversely associated with depressive symptoms in adolescents. However, there have been few studies in older populations. This cross-sectional study investigated the association between family mealtime frequency and depressive symptoms in elderly Koreans. Methods: This study analyzed 4,959 elderly men and women (aged 65 years or older) who participated in the Korea National Health and Nutrition Examination Survey. Self-administered questionnaires were used to assess depressive status, family mealtime frequency, and covariates. Multiple logistic regression analysis was performed to evaluate the association using the eating alone group as a reference. Results: After adjusting for all covariates, participants who had family meals 3 times a day had fewer depressive symptoms than the eating alone group; adjusted odds ratios (ORs) (95% confidence intervals [CIs]) were 0.72 (0.58-0.89) for point depressiveness/anxiety and 0.73 (0.56-0.94) for depressiveness lasting for at least 2 weeks. In suicidal ideation, the OR (95% CI) of eating with family twice a day was significant after full adjusting for covariates at 0.67 (0.50-0.88). Conclusion: Family mealtimes were closely associated with depressive symptoms in elderly Koreans, which suggests that maintaining intrafamilial bonding is important for mental health in an older population.

Background: Compared with other chronic diseases, hearing loss is generally overlooked from the perspective of disease burden. However, hearing loss is emerging as an important issue in the current society. The objective of this study was to investigate disease burdens and marginal utilities associated with hearing loss and other chronic diseases. Methods: This study analyzed the cross-sectional data of 32,986 participants aged 19 years and older who completed the Korea National Health and Nutrition Examination Surveys between 2009 and 2013. Additionally, this study used the pure tone audiometric test, European Quality of Life-Five Dimensions Questionnaire, and chronic disease status. The data were analyzed using a multiple linear regression method. Results: The data of 23,297 people who underwent a pure tone audiogram and completed the European Quality of Life-Five Dimensions Questionnaire were used in this analysis. The marginal utility of hearing loss ranked fifth among nine chronic diseases. The estimated loss of quality-adjusted life years associated with hearing loss was -93.69 years per 100,000 people, which is similar to other chronic diseases. Conclusion: This study assessed the marginal utilities and public burdens of hearing loss and eight chronic diseases in a South Korean population. Although the values may vary depending on country and race, this study may provide an indispensable foundation for more detailed studies on hearing loss.

Background: The purpose of this study is to provide the data for discussions related to oral health promotion policies for single-person households by analyzing the status of unmet dental needs and related factors in single-person households in Korea, based on the Anderson model. Methods: The data, obtained from 544 single-person households of those over 20 years old who were targeted for the 6th Korea National Health and Nutrition Examination Survey, were analyzed through a complex sample frequency analysis, complex sample cross analysis (Rao-Scott chi-square test), and complex sample binary logistic regression analysis on a complex sampling design. Results: The most frequently given reason for an unmet dental need among single-person households was economic (52.4%). Factors related to the unmet dental needs of single-person households are smoking, which is a predisposing factor; personal income levels, which are an enabling factor; chewing discomfort; and limited daily activities, which are need factors. Smokers, the high-income group, the chewing-discomfort group, and the limited activity group showed high unmet dental care experience. Smokers had a 2.75 times higher rate of unmet dental care than non-smokers, and the high-income group had a 5.29 times higher rate of unmet dental needs than the median group. The rate of unmet dental needs for the chewing discomfort group was 3.27 times higher than the non-chewing discomfort group, and the limited activity group had a 7.87 times higher rate of unmet dental needs than the non-limited activity group. Conclusion: It is necessary to map out policies designed to help maintain and promote met dental needs considered to be internally heterogeneous to single-person householders, based on the Anderson model.
