Fatigue crack propagation life of weld toe crack through residual stress field was estimated with Elber's crack concept. Propagation of weld toe crack is heavily influenced by residual stress caused by welding process, so it is essential to take into account the effect of residual stress on the propagation life of weld toe crack. Fatigue crack at transverse and longitudinal weld toe was studied respectively, which represent typical weld joint in ship structure. Numerical and experimental studies are performed for both cases. Residual stress near weldment was estimated through nonlinear thermo-elasto-plastic finite element method, and residual stress intensity factor with Glinka's weight function method. Effective stress intensity factor was calculated with Newman-Forman-de Koning-Henriksen equation which is based on Dugdale strip yield model in estimating crack closure level U at different stress ratio. Calculated crack propagation life coincided well with experimental results.

Purpose: This is a descriptive correlation study to confirm the effect of stress and anxiety caused by COVID-19 on the quality of life of small business owners in an area under environment of COVID-19. Methods: The participants were 150 small business owners in an area. The collected data were analyzed by descriptive statistics, an independent t-test, a one-way ANOVA, Pearson's correlation coefficients, and multiple regression with the SPSS 25.0 Program. Results: The stress of small business owners averaged 3.67±0.65 out of 4 points, anxiety of COVID-19 was 2.65±0.52, and quality of life was 75.61±20.26 out of 130 points. The quality of life showed a significant negative correlation with 'fear of infection' (r=-.42, p<.001), 'difficulties caused by social distancing' (r=-.49, p<.001) in the stress subdomain, and anxiety (r=-.61, p<.001). On the other hand, stress, 'fear of infection' (r=.50, p<.001), 'difficulties caused by social distancing' (r=.60 p<.001), 'anger against others' (r=.35, p<.001) and anxiety showed positive correlation. Factors affecting the quality of life of the subjects were 'fear of infection' in the stress subdomain (β=-.23, p=.003), anxiety (β=-.45, p<.001), and residential area (J zone) (β=-.16, p=.030). These factors explained 47.0% of the variance. Conclusion: In order to enhance the quality of life of small business owners in an area, it is required to reduce stress and anxiety. In addition, it is necessary to prepare an intervention program that can reduce stress and anxiety of small business owners.

The objective of this study was to determine phosphorus effects on drought stress-induced oxidative stress in Kentucky bluegrass. Drought stress was induced by reducing of water to plants in pots. Two types of phosphorus were applied as potassium phosphate (P) or potassium phosphonate (PA). Application of phosphorus was efficient to ameliorate the adverse effects of drought. Osmotic potential, total chlorophyll and carotenoid content were significantly decreased by drought stress, but was relieved by P or PA application. Superoxide (O₂^•-) concentration was significantly increased more than 14-fold under drought-stressed plants, was accompanied with increase of hydrogen peroxide (H₂O₂) and lipid peroxidation (MDA). However, malondialdehyde (MDA) was much less in P or PA applied plants under drought stress condition. Activities of catalase (CAT), ascorbate peroxidase (APX) and guaiacol-peroxidase (GPX) were largely increased by drought stress and its increase rate was much higher in P or PA applied plants except APX. These results indicate that drought stress-induced oxidative stress is alleviated by P or PA application due to the increase of activities of antioxidant enzymes.

Recently, Luu suggested fatigue life equation that uses every term of the Crossland equation with stress gradient effect. Luu’s model, however, has a limit of being unable to coverage small radii that are less than a specified length. Furthermore, rolling model has a very small contact area compared to the rolling element size, and fatigue failure occurs on the small radius such as surface asperity by cyclic loading. Therefore, it is necessary to modify fatigue life equation in order to enable fatigue analysis for a small radius. In this paper, the fatigue life considering a stress gradient effect in rolling contact was obtained using Luu’s modified equation. Fatigue analysis was performed to study the effect of stress gradient on the fatigue life using newly adopted equation and to compare the results with pervious models. In order to do this, a series of simulation such as surface stress analysis, subsurface stress analysis, and fatigue analysis are conducted for two rolling balls of same size that contact each other. Through such a series of processes, the fatigue life can be calculated and equation that is proposed in this paper evaluates the fatigue life in case the contact area is small.
