Purpose: The aim of this study was to analyze breast cancer screening behaviors in working women. Method: A total of 354 women over 20 years of age were recruited from three major occupational settings by convenience sampling. The Champion's Health Beliefs Model Scale-Korean version and a structured questionnaire for measuring regularity and accuracy of breast self-examination(BSE) were used. Data were analyzed using descriptive statistics, $x^$-test, ANOVA, and Duncan post hoc tests. Result: Women who have performed BSE and had both BSE and clinical tests were 49.2% and 32.8%, respectively, while 36.7% of the participants had none of the screening. The screening patterns were significantly different by individual characteristics of age, occupation, experiences of breast disease, education at workplace, and by the level of confidence in health beliefs (p<.01, p<.05). Only 4 % of women performed BSE regularly and the level of accuracy of the BSE was very low as well. Conclusion: Education at the workplace needs to emphasize the recommended guidelines and further increase the quality and results of the BSE for women's health.

In this study, Cu-5Ni-10Sn(wt%) spinodal alloy was manufactured by gas atomization spray forming, and the microstructural features and mechanical properties of Cu-5Ni-10Sn alloy have been investigated during homogenization, cold working and age-hardening. The spray formed Cu-5Ni-10Sn alloy consisted of an equiaxed microstructure with a mixture of solid solution ${\alpha}$-(CuNiSn) grains and lamellar-structure grains. Homogenization at $800^{\circ}C$ and subsequent rapid quenching formed a uniform solid solution ${\alpha}$-(CuNiSn) phase. Direct aging at $350^{\circ}C$ from the homogenized Cu-5Ni-10Sn alloy promoted the precipitation of finely distributed ${\gamma}$' or ${\gamma}-(Cu,Ni)_3Sn$ phase throughout the matrix, resulting in a significant increase in microhardness and tensile strength. Cold working prior to aging was effective in strengthening Cu-5Ni-10Sn alloy, which gave rise to a maximum tensile strength of 1165 MPa. Subsequent aging treatment slightly reduced the tensile strength to 1000-1100 MPa due to annealing effects.

Backgrounds: Irregular and unpredictable work schedules have become more common in most societies. The purpose of this study was to investigate the association between unpredictable work schedules and depressive symptoms in Korea. Methods: Data from 34,486 workers who participated in the Korean Working Condition Survey in 2017 were used. Unpredictable work schedules were measured by questions about the frequency of changes in work schedule and limited advanced notice. Depressive symptoms were assessed by a single item asking if the participants had depressive symptoms over the last 12 months. Multivariable-adjusted logistic regression analysis was used to calculate odds ratios (ORs) for high depressive symptoms. Results: The OR for depressive symptoms was significantly higher in the workers with unpredictable work schedules compared to those with predictable work schedules after controlling for age, sex, education, salary, marital status, occupation, contract period, full-time versus part-time, shift work, weekly working hours, and having a child under the age of 18 years (OR = 2.43, 95% confidence interval 1.93-3.07). Conclusion: Unpredictable work schedules were associated with depressive symptoms controlling for the other dimensions of precarious employment in a representative working population in Korea.
