This study was designed to examine the depressive symptoms of individuals who became visually impaired and identify factors associated with the symptom. For the analysis, data from the Korean National Survey of Individuals with Disability 2014 was used. Adults between the ages of 20 and 60 years who became visually impaired after the first year of birth were included with a total of 235 individuals in the final sample. To identify the determinants of their depressive symptoms, a multivariate logistic regression analysis was conducted. The results showed that about twenty percent of the respondents reported having depressive symptoms in the past year. Among the sociodemographic factors, age, gender, and marital status were identified as significant predictors, while smoking status, stress level, and self-reported health status were identified as important health-related predictors. Among the disability-related factors, the length of disability and activities of daily living level were found to be significantly associated with the likelihood of experiencing the symptom. The results indicate the need for practitioners working with visually impaired populations to be better aware of the risks of depression and develop a wide array of preventive measures and techniques to work with individuals suffering from depression.

Purpose: This study examined the association between fruit and vegetable intake and mental health in Korean adolescents. Methods: This study used the data from the 2014-2017 Korea Youth Risk Behavior Survey, a national cross-sectional survey on 137,101 boys and 130,806 girls aged 12-18. Fruit and vegetable intake was assessed based on the frequency of consumption. The outcome variables were the perceived happiness, perceived stress, depressive symptom and suicidal ideation over the previous 12 months. Logistic regression models were used after adjusting for the demographic, life style and other dietary factors. Results: Only 34% and 29% of Korean adolescents consumed fruits more than 5 times/week and vegetables more than 2 times/day, respectively; whereas 37%, 25% and 12.2% of Korean adolescents had perceived stress, depressive symptom and suicidal ideation, respectively. After adjusting for the confounding variables, the greater consumption of fruit and vegetable were all associated with a higher odds of perceived happiness; the adjusted odds ratios (AORs) (95% CI) were 1.53 (1.46-1.60) in boys and 1.82 (1.73-1.90) in girls who consumed fruit ≥ 5 times/week, and 1.65 (1.54-1.76) in boys and 1.62 (1.51-1.72) in girls who consumed vegetable ≥ 2 times/day. In contrast, the consumption of fruit or vegetable were all significantly associated with a lower odds of perceived stress, depressive symptom, and suicidal ideation; the AOR (95% CI) were 0.70 (0.67-0.73), 0.88 (0.84-0.93), and 0.78 (0.73-0.83) in boys who consumed fruit 3-4 times/week, and 0.71 (0.67-0.76), 0.88 (0.81-0.94), and 0.68 (0.62-0.74) in boys who consumed vegetable 5-7 times/week. Similar associations of fruit or vegetable consumption with perceived stress, depressive symptom, or suicidal ideation were found in girls. Conclusion: These findings provide evidence that increasing fruit and vegetable intake is important for better mental health among adolescents.

The purpose of this study is to analyse the characteristics of Manning's roughness coefficient according to change of discharge by using observed data obtained from a stable gravel-bed river and to investigate the applicability of the relevant existing empirical methods to it. Observed water level and discharge data are used as input data for the USGS computer program NCALC model for calculation of the roughness coefficient. Calculated values are compared with roughness values which are estimated with four widely used methods. The results show that though the empirical methods are able to give similar roughness values only for flood flow, they seem to have rather high uncertainty because of necessity of subjective judgement and differences of resultant values. Roughness coefficients for normal-low flow cannot be estimated from the existing empirical formulae. Especially, using the Manning equation for calculating them should be careful as this provides a wide range of estimated values in normal-low flow. The relations between the roughness coefficient and characteristic size of bed materials are different from them in flood flow even though they have a close relations.

To investigate the perception of the correlation between systemic diseases and oral health among some university students. The questionnaires were conducted on 485 students from 3 universities in Gwangju. As a result of the study, the female was higher than the male and was the highest in the fourth grade. Subjective health status, drinking status, smoking experience, and exercise were not significantly different in recognizing the association between systemic disease and oral health. The group with experience in oral health education recognized 3.18, and the group that practiced educational contents was highly recognized as 3.21. There was a significant difference between the two groups. Multiple regression analysis showed that major factor and grade factor influenced the perception of association between systemic disease and oral health. Therefore, it is necessary for university students to recognize the importance and necessity of periodical oral examinations. It is thought that the incidence of disease should be strengthened and enforced to recognize that there is a correlation with various diseases.
