  • This study was conducted to confirm the mediating effect of self-esteem and social support in the relationship between life stress and depression in middle-aged men. Data analysis was performed using the SPSS/WIN 25.0 program, t-test, ANOVA, pearson's correlation coefficient, SPSS Process Macro (Model 4), and bootstrapping approach. As a result of this study, when considering the effect of self-esteem, a parameter in the relationship between life stress and depression, the direct effect of life stress on depression was .49. Considering the effect of social support as a parameter, the direct effect of life stress on depression was .50. That is, when the parameters were not considered, life stress decreased compared to the overall effect of .62 on depression. Through this, it was confirmed that self-esteem and social support had a mediating effect in the relationship between life stress and depression.

  • The purpose of this study was to examine the effect of achievement motivations of university students on depression and the mediating effect of self-esteem in these relationships. For this, data were collected from 267 university students enrolled in universities in Y city, and analyzed using SPSS 22.0 and SPSS PROCESS macro 3.3. As a result of the study, first, it was found that the achievement motivation of university students had a significant positive effect on self-esteem, a parameter. Second, it was found that the achievement motivation of university students had a significant negative effect on depression. Third, in the relationship between achievement motivation and depression in university students, self-esteem, a parameter, was found to have a significant negative effect on depression, whereas achievement motivation did not have a significant effect on depression. In view of this, it was confirmed that self-esteem was completely mediated in the effect of achievement motivation of university students on depression. Based on the results of this study, the implications and limitations of this study were discussed, and support plans and follow-up studies for university students were suggested.

  • The present work is concerned with characterization of surface roughness and inhomogeneity of four kinds of hot-rolled carbon steels in terms of the fractal dimension and the depression parameter by using image analysis method and electrochemical impedance spectroscopy, respectively. From the analysis of the 3D AFM image, it is realized that all the hot-rolled steel surfaces show the self-affine fractal property. The values of the fractal dimension of the hot-rolled steels were determined by the analyses of the AFM images on the basis of both the perimeter-area method and the triangulation method. In addition, the Nyquist plots were found to be depressed from a perfect semicircle form. From the experimental findings, the changes in the values of the fractal dimension and the depression parameter with chemical composition have been discussed in terms of the change in the value of hardness of base steel.

  • The objectives of this study are to research the frequency of depression symptom in patients with voice disorders and to investigate parameters associated with depression from voice evaluation. A hundred ninety six patients(106 males and 90 females) who had been diagnosed with voice disorders first in their lifetime were selected. All the patients were examined by laryngeal stroboscopy. For depression and voice study, personal interview, acoustic and aerodynamic analysis, voice handicap index(VHI), reflux symptom index(RSI), and beck depression index(BDI) were done respectively. Mild to severe BDI were seen in 26.2%(52 patients) of the whole patients. A BDI mean score of female patients was $8.8{\pm}7.5$ which was higher than that of male patients($5.6{\pm}6.6$), the difference observed being statistically significant(p<0.001). In the acoustic analysis, the score of sent_duration parameter was increasing in the patients with depression, which was significantly higher than the score of the patients without depression(p<0.05). In the addition, the scores of VHI and RSI were higher in the patients with depression(p<0.001). Our findings suggest that the prevalence of depression in patients with voice disorders is related to female, speaking velocity, and self-questionnaire. This result can be used for psychologically based approach to therapy.

  • Because it is known that bivalve hearts contain various modulatory systems activated by neuroendocrine substances, it was examined whether different classes of endogenous and synthetic drugs of neuroendocrinological importance can influence cardiac functions of the Pacific oyster Crassostrea gigas. Cholinergically active agents acetylcholine and carbachol increased heart rates while diminishing cardiac contractility. Adrenergically active substances norepinephrine (NE) and epinephrine (Epi) also induced heart rate increase and contractility decrease. An $\alpha_1$-adrenergic receptor-selective agonist phenyephrine (PE) failed to modulate either parameter. The Epi-induced heart rate increase and contractile depression were both blocked significantly by non-selective $\beta_1/\beta_2$-adrenergic antagonist propranolol. A $\beta_1$-selective antagonist atenolol prevented Epi-induced heart rate decrease but not the contractile depression, suggesting possible $\beta_2$ receptors for Epi-induced contractile depression. The three autacoids examined exerted discrete responses: histamine increased heart rate and depressed contraction; $\gamma$-amino-butyric acid increased both parameters; serotonin failed to change either parameter. The 5 piscine anesthetic agents examined, MS-222, benzocaine, quinaldine, urethane, pantocaine and pentobarbital, all failed to influence the cardiac function of oysters. Collectively, activities of neuroendocrinologically acting agents in mammals showed unexpected and distinct activities from those in mammalian cardiovascular systems. These results obtained from substances of different physiological functions can serve as a basis for understanding neuroendocrine control of the heart function in Pacific oyster.

  • Purpose: This study was performed to understand health perception, health practice, and depression of the elderly and to identify their depression level according to health perception and health practice. Method: The subjects were 463 elders who have lived in the Jeju Island and data were collected from June to August in 2005. Data were analyzed by SPSS 10.0. Result: The mean score of depression was 12.94 out of 30, and had a statistically significant correlation with educational level (F=2.943 p=.033), occupation (F=4.611. p=.010), and the number of chronic diseases (F=5.303. p=.001). When the cutoff of 18 points was applied based on Jung et al. (1997), the depression ratio was 12.4%, and when the cutoff parameter by Yesavage et al (1993) was applied, themoderate depression ratio was 74.8% and the severe depression ratio was 3.4%. In health recognition, consideration of usual health state had a significant correlation with depression (F=3.553 p=.007) but consideration of health state compared to the previous year wasn't. In health practice, sleeping was in a significant correlation with depression (F=3.574 p=.011), but smoking, alcohol drinking, exercise, and rest were not. Conclusion: Based on above results, we need further study on another sample group and the development, application, and verification of health management, education, and counseling programs for the elderly. Also, additional research should be made on significant factors of elderly depression.

  • The purpose of this study was to investigate the effects of the instrumental activities of daily living (IADL) and depression on the life satisfaction of the rural elderly. The research subjects of this study were 1,000 people aged 65 years and over living in the rural areas of Korea. The data were collected using a questionnaire with direct interviews and analyzed using SPSS ver. 18.0 for Windows. The results of this study were as follows: First, the rural elderly's depression was affected by the IADL, cost of living, education level, and farming variables. The higher the IADL, the more sufficient the cost of living, the higher the education level and the more the farming time that the rural elderly had, the lower was the level of depression that they had. Second, the life satisfaction of the rural elderly was affected by the cost of living, depression, IADL, need for life services, and gender. The more sufficient the cost of living, the lower the level of depression, the higher the IADL, the less the need for life services, the higher was the life satisfaction that they experienced. Third, the results of the path analysis revealed that life satisfaction was influenced both directly and indirectly. The factors that affected life satisfaction directly were the cost of living, IADL, need for life services, and gender. The factors that affect life satisfaction indirectly were the IADL, cost of living, education level, and farming. Among them, farming and education level influenced life satisfaction indirectly through the parameter variables of depression.

  • Objectives : Despite the lack of domestic research, eating alone has been reported to be related to depression. We investigated correlation between eating alone, and depression, among women age 65 and older. Methods : Among women registered in the Korea National Health and Nutrition Examination Survey data, 1,119 elderly in 2014, and 1,189 in 2016, were analyzed. Eating alone and the degree of depression were assessed, using a questionnaire and the Patient Health Questionnaire-9 respectively. The relationship between eating alone and depression, was analyzed using multilevel logistic regression. Results : In 2014 data, eating alone had significant effect on depression, as the explanatory power is increased to 30.4% in a 'three meals eating alone a day' group (${\beta}=0.128$, p<0.05), when the eating alone parameter is added to demographic factors and health characteristics. In 2016, exploitation of 'the frequency of eating alone' variable led to increment of explanatory power to 22.3%, that was not statistically significant. Conclusion : The result of this study suggests that eating alone among women age 65 and older, was a risk factor of depression in 2014, and is becoming a new life pattern as a social and cultural phenomenon in 2016.
