Background/Context: Research on Chinese immigrant parents tends to focus on their high levels of educational involvement and its positive impact on their children's exceptional educational performances. Relatively little research has been conducted to understand the challenges Chinese immigrant parents face in helping their children with school and the resulting influence on parent-child relations and children's adaptation. Focus of Study: In this paper, we examined how immigration reshapes parental involvement in these Chinese immigrant families and its subsequent influence on parent-child relations. Setting: The research was conducted in the metropolitan area of a northeastern city in the United States. Participants: Our participants were 72 Chinese immigrant children and their parents. Research Design: Our study utilizes longitudinal interview data with open-ended questions. Open, axial, and selective coding procedures were used in qualitative data analysis. Findings/Results: Our findings suggest that when parents face multiple challenges in their adaptation after migration, they often experience a feeling of powerlessness especially in dealing with their children's schooling. This then forces the children to be precociously independent. This dynamic puts strain on parent-child relations and has a negative impact on children's adaptation. Conclusions/Recommendations: It is important for schools and other social institutions working with Chinese immigrant families to reach out to parents by providing them with more information and resources to be more involved in their children's education. Immigrant and local communities can also help by offering parent and youth programs to help improve parental involvement and parent-child relations in Chinese and other immigrant families.

Gonadotropin-releasing hormone (GnRH) agonist has been used in the treatment of a wide variety of sex-hormone-related diseases, as the administration of GnRH agonist can alter the secretion of gonadotropin and sex hormones. Recently, we found that the long-acting GnRH agonist aggravated hyperthyroidism and induced painless thyroiditis. This is the first report to demonstrate the association of thyroid dysfunction with GnRH agonist injection in Korea. Here, we report three cases and emphasize the clinical importance of this aggravating factor in autoimmune thyroid disease. [ABSTRACT FROM AUTHOR]

Hypothyroidism should be treated in pregnancy, because it has been associated with an increased risk of adverse pregnancy complications, as well as detrimental effects upon fetal neurocognitive development. The goal of L-thyroxine (LT4) treatment is to normalize maternal serum TSH values within the trimester-specific pregnancy reference range. 50% to 85% of hypothyroid women being treated with exogenous LT4 need to increase the dose during pregnancy. In this study, we report a case of a 29-year-old woman with hypothyroidism who had been in remission and discontinued LT4 treatment during her pregnancy. Three months after delivery she had a relapse of hypothyroidism and was retreated with LT4. Many factors can influence the gestational requirement for LT4, therefore maternal serum TSH should be monitored and the LT4 dose should be adjusted in pregnant patients with treated hypothyroidism.

One of the main missions of Microfinance Institutions is to improve the status of under-privileged people. However, MFI's mission drift or enhancement can occur under adverse economic condition. In this paper, we investigate the direction of changes in supporting women borrowers who make up the majority of the poor by using the lending patterns of Latin American and Caribbean MFIs during the recent global financial crisis. P control chart is applied to detect assignable changes in the lending rate to woman over different MFIs. In order to identify related characteristics to the outlying MFIs identified from the P control chart, we perform logistic regression analysis. Our study results can contribute to understand MFI's mission change in terms of supporting women borrowers and identify the related characteristics of MFIs. [ABSTRACT FROM AUTHOR]

Tracer tests were conducted using floaters equipped with a global positioning system (GPS) to investigate the turbulent mixing of the floating pollutant at the surface of natural rivers. The position data were collected by tracking the floaters at different reaches of the Nakdong River in Korea, and the diffusion coefficients were calculated by applying the moment method to the floater distribution data collected. While applying the moment method, the diffusion coefficient was calculated from the time evolution of variance of the particle distribution, which becomes the distance from the centroid of the particle cloud, based on the homogeneous turbulence assumption and the ergodic hypothesis of the turbulent mixing. Analysis of the trajectories of GPS floaters showed that the horizontal mixing in the initial mixing stage was hampered by the interaction and collision between floaters. The experimental results revealed that the dimensionless streamwise diffusion coefficients were larger, in the range of 0.11-0.56, while the spanwise component was in the range of 0.02-0.16. The simulation results using the Lagrangian particle tracking model of the Environmental Fluid Dynamics Code program showed that the discrepancy between the predicted values and the observed data in the initial time gradually decreased as time elapsed.

To investigate the two-dimensional dispersion characteristics of the dissolved contaminant in natural rivers, tracer experiments were performed based on the instantaneous injection of Rhodamine WT solution into small- to medium-sized rivers in Korea. The relations between the dispersion coefficients and hydraulic and geometric variables of the river were analyzed in depth. The experimental results show that transverse dispersion coefficient tends to increase as the friction term, U/U*, and the channel aspect ratio,W/H, increase. The effect of the channel curvature on the rate of transverse mixing was found to be very distinct in that DT/HU* has a linear relation with UW/U*Rc, even though the slope of the fitted line in the plot of DT/HU* versus UW/U*Rc in a log-log scale was much smaller than the slope of the equation by Yotsukura and Sayre. The longitudinal dispersion coefficient also tends to increase as U/U* and W/H increase. However, DL is rather insensitive to the channel curvature. The values of the longitudinal dispersion coefficient from field studies are much higher than the theoretical value suggested by Elder. The observed longitudinal dispersion coefficient is one order of magnitude larger than Elder's coefficient, and DL/DT of this study ranges 26.6-332. [ABSTRACT FROM AUTHOR]

Background: We investigated the association between the severity of non-alcoholic fatty liver disease (NAFLD) and the estimated 10-year risk of cardiovascular disease (CVD) calculated by Pooled Cohort Equation (PCE) and Framingham risk score (FRS). Methods: A total of 15,913 participants (mean age, 46.3 years) in a health screening program were selected for analysis. The presence and severity of fatty liver was assessed by abdominal ultrasonogram. Subjects who drank alcohol more than three times a week were excluded from the study. Results: Among the participants, 57.6% had no NAFLD, 35.4% had grade I, 6.5% had grade II, and 0.5% had grade III NAFLD. Mean estimated 10-year CVD risk was 2.59%, 3.93%, 4.68%, and 5.23% calculated using the PCE (P for trend <0.01) and 4.55%, 6.39%, 7.33%, and 7.13% calculated using FRS, according to NAFLD severity from none to severe (P for trend <0.01). The odds ratio for ≥7.5% estimated CVD risk calculated using the PCE showed a higher correlation with increasing severity of NAFLD even after adjustment for conventional CVD risk factors (1.52, 2.56, 3.35 vs. the no NAFLD group as a reference, P<0.01) compared with calculated risk using FRS (1.65, 1.62, 1.72 vs. no NAFLD group as a reference, P<0.01). Conclusion: In our study of apparently healthy Korean adults, increasing severity of NAFLD showed a higher correlation with estimated 10-year CVD risk when calculated using the PCE than when calculated using FRS.
