  • The angular dependence of active dosimeters, EPD, is analysed and compared with that of passive dosimeters, OSLD, after evaluating their relative response and uncertainty of measurement, where it is known that the personal use of them has been increased recently. There appeared a minor variation for average relative response of OSLD in the horizontal and vertical directions within the range $0^{\circ}{\sim}{\pm}90^{\circ}$, which are 0.97 and 0.95 respectively. The variations of angular dependence in the same situations with OSLD are 0.65 and 0.62, respectively, which also reveals a negligible effect on the overall uncertainty. EPDs within the interval $0^{\circ}{\sim}{\pm}60^{\circ}$ for horizontal and vertical directions are 0.94 and 0.97, respectively. These satisfy the requirements of IEC 61526. Uncertainties about the dependence of direction from horizontal and vertical directions are 0.44, 0.40, respectively. The impact of these uncertainties on the overall uncertainty was negligible. However, we observed a significant change in reactivity: the relative reactivities for $+90^{\circ}$ and $-90^{\circ}$ from the horizontal direction are 0.60, 0.37, while that form vertical direction is 0.06. The direction dependence of OSLD was superior to EPD in the range of $0^{\circ}{\sim}{\pm}90^{\circ}$. There appeared a rapidly changing structural features in EPD response for a certain direction. Therefore, we conclude that concurrent use of passive dosimeters and auxiliary dosimeter provides accurate data for personal dose measurements.

  • Purpose: To Examine the status of health behavior and identify the influencing factors of health behavior among pregnant women. Method: The participants were 1011 pregnant women who visited outpatient hospital of in Yanbian, China. Participants were interviewed using Chinese version of Edinburgh Postnatal Depression Scale(EPDS), Perceived Social Supports(PSSS), general self-efficacy, and characteristics. Descriptive statistics, t-test, ANOVA, pearson correlation coefficient, binary logistic regression were used for data analysis with SPSS 19.0. Results: The mean score of health behavior was $28.93{\pm}6.59$ scores(0~45 scores). Antepartum depression(OR=0.94[0.90-0.98]), perceived social supports(OR=1.07[1.05-1.09]), self-efficacy(OR=1.36[1.04-1.79]) were predictor of health behavior among pregnant women, on the contrary to this the characteristics of pregnant women were not statistically significant. Conclusion: The implement of the health behavior among pregnant women was not ideal. It's necessary to develop a health behavior intervention focus on antepartum depression, social support, and self-efficacy for pregnant women.

  • Postpartum depression(PPD) of women with depression increased frequency of thyroid disease, and so the correlations for depression and thyroid disease has been the subject of discussed whether. The purpose of this study was to predict the prevalence of PPD and the correlation between PPD and thyroid disease through ultrasonography. January 2010 to November 2011, Obstetrics & Gynecology in M-clinical center admitted 230 patients within 1 year postpartum were enrolled. EPDS by PPD scale depression screening and general characteristics of subjects were investigated and thyroid was examined that ultrasonography and thyroid blood tests. A total of 230 patients non PPD group were 53.0% and PPD group were 47.0%. In ultrasonography, among 27 patients who changed in size of thyroid, non PPD group were 14.8% and PPD group were 85.2%. Among 124 patients who thyroid nodules were presence, non PPD were 35.8% and PPD group were 64.2%. In ultrasonography, PPD group were higher incidence than non PPD group were changes in size of thyroid and the presence of nodules. There was significant difference between the changed in size of thyroid and thyroid nodules were presence the two group. Definitive histopathological diagnosis was benign in 33 patients (non PPD group were 45.5%, PPD group were 54.5%), malignancy in 5 patients (only PPD group were 100%), thyroiditis in 3 patients (non PPD group were 33.3%, PPD group were 66.7%). The results of thyroid blood tests, abnormal TSH level were 7 patients (non PPD group were 28.6%, PPD group were 71.4%) and abnormal Free T4 level were 9 patients (non PPD group were 44.4%, PPD group were 55.6%). There was no significant difference between the abnormal TSH level and Free T4 level of the two group. 5 patients were diagnosed as thyroid dysfunction. Of these, 2 patients were subclinical hyperthyroidism in non PPD group, 2 patients were subclinical hyperthyroidism and 1 patient was subclinical hyperthyroidism in PPD group. This study was significant the correlation between PPD and thyroid gland disease through ultrasonography. And the objective results of this study might be able to provide guideline that understanding, prevention and treatment for PPD and thyroid disease.
