Limited empirical study of the career development of Asian Americans in general and Korean Americans in particular has been conducted. The authors present the results of a theory‐based exploration of the career goals of Korean American university students in which ethnic identity, self‐efficacy, outcome expectations, and career interests were used to predict goal intentions for science and nonscience careers. Outcome expectations and career interests predicted a moderate amount of variance in science career goal intentions and a moderate to large amount of variance in nonscience career goal intentions. Korean American students' career goal development seems similar to that of American college students. 相似文献
Objective: The objective of this study is to investigate the impact of metabolic status on associations of serum vitamin D with hypogonadism and lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH).
Patients and methods: A total of 612 men underwent physical examination, biochemical/hormonal blood testing, and transrectal prostate ultrasound. Moreover, the subjects filled out standard questionnaires for identification and grading of LUTS and hypogonadism symptoms. Parameters were statistically compared with independent t-tests and correlation analyses.
Results: Vitamin D levels positively correlated with total testosterone (TT) but not with prostate volume or International Prostate Symptom Score (IPSS). Patients with metabolic syndrome had significantly lower vitamin D levels, which were not correlated with TT, prostate volume, or IPSS. However, vitamin D was positively correlated with TT, and negatively correlated with prostate volume and quality-of-life IPSS in subjects without metabolic syndrome.
Conclusion: The clinical usefulness of vitamin D for treatment of hypogonadism or LUTS/BPH varies according to metabolic status. 相似文献
Robust parameter designs (RPDs) enable the experimenter to discover how to modify the design of the product to minimize the effect due to variation from noise sources. The aim of this article is to show how this amount of work can be reduced under modified central composite design (MCCD). We propose a measure of extended scaled prediction variance (ESPV) for evaluation of RPDs on MCCD. Using these measures, we show that we can check the error or bias associated with estimating the model parameters and suggest the values of α recommended for MCCS under minimum ESPV. 相似文献
ABSTRACTGuided by the Person-Environment Fit perspective, we investigated the extent to which personal and environmental factors influence depression among community-dwelling adults. The data came from the special section about community-based service utilization in the 2012 Health and Retirement Study (N=1,710). Although community-based service was not significantly associated with depression after controlling for covariates, respondents with functional limitations and living alone were less likely to be depressed when using community-based services. This study demonstrates the different associations between community-based services and depression depending on personal needs. It discusses the importance of community-based services for aging-in-place policy, particularly among vulnerable populations. 相似文献
The new rural cooperative medical system (NCMS) is the primary form of social insurance in rural China. This study aims to explore how the NCMS influences the health care seeking behaviors of middle-aged and older Chinese, considering the family and community contexts. A series of multi-level (three-level) models using data from the first wave of the China Health and Retirement Longitudinal Study (CHARLS) are used. We find that the presence of NCMS coverage has a statistically significant association with seeking inpatient and outpatient care but not physical checkups among middle-aged and older rural Chinese: Rural residents insured by NCMS were more likely to seek inpatient and outpatient care than people who were not insured. Other factors at the individual level (such as self-perceived health and number of doctor-diagnosed chronic diseases), the family level (such as living arrangements and household expenditures), and the community level (such as the presence of township hospitals within the community) are also significant predictors of health care seeking behaviors. 相似文献
