The objective of this study was to determine the presence of corticosteroids in illegal herbal medicines using ultra‐high‐performance liquid chromatography–tandem mass spectrometry. We collected 212 herbal medicine samples that were advertised as being effective for treatment of joint pain and bone aches. Samples were from the Korean commercial market during a span of four years (2010–2013), and the method was validated. The limits of quantification ranged from 0.47 to 15.0 ng/mL, and recoveries ranged from 80.6% to 119.5%. The intra‐ and interday precision ranged from 0.18% to 8.82% and from 0.09% to 8.96%, respectively. Among the samples, three samples (1.4%) were identified as adulterants. Dexamethasone was the only compound detected in the adulterated products. As the corticosteroid–adulteration of herbal medicines may become a major problem and lead to side effects, the continued development of screening procedures for herbal medicines is critical. 相似文献

The new emphasis on quantification of evidence has led to perplexing courtroom decisions and it has been difficult for forensic scientists to pursue logical arguments. Especially, for evaluating DNA evidence, though both the genetic relationship for two compared persons and the examined locus system should be considered, the understanding for this has not yet drawn much attention. In this paper, we suggest to calculate the match probability by using coancestry coefficient when the family relationship is considered, and thus the performances of the identification values depending on the calculation of match probability are compared under various situations. 相似文献

Allele frequencies for nine STR loci namely, TH01, TPOX, CSF1PO, vWA, FESFPS, F13A01, D13S317, D7S820 and D16S539 were obtained from a sample of 437 unrelated individuals living in Chungcheong-do, South Korea. 相似文献

Cartel Theory (and partisan theory more generally) expertly explains the functioning of the U.S. Congress. However, as a theory originally developed to study a single legislature where the institutional context differs greatly from that found in other presidential democracies, its applicability to these democracies has been questioned. Between one extreme represented by the United States (where legislators control their own political future) and the other represented by centralized party systems (where the national party leadership controls legislators' future) exists an intermediate group of democracies where subparty bosses are the key actors, controlling the future of subsets of a party's legislative delegation. We analyze one of these intermediate democracies, Argentina, and demonstrate the general applicability of Cartel Theory to an institutional context that differs notably from that found in the United States. We highlight how the theory can be adapted to a political system where subparty bosses, not individual legislators, are the most relevant political actors . 相似文献

Measurement of Uncertainty for Aqueous Ethanol Wet‐Bath Simulator Solutions Used with Evidential Breath Testing Instruments 下载免费PDF全文
Rong‐Jen Hwang Ph.D. Jada Beltran B.A. Craig Rogers B.A. Jeremy Barlow M.S. Gerasimos Razatos M.B.A. B.S. 《Journal of forensic sciences》2016,61(5):1359-1363
Aqueous ethanol wet‐bath simulator solutions are used to perform calibration adjustments, calibration checks, proficiency testing, and inspection of breath alcohol instruments. The Toxicology Bureau of the New Mexico Department of Health has conducted a study to estimate a measurement of uncertainty for the preparation and testing of these wet‐bath simulator solutions. The measurand is identified as the mass concentration of ethanol (g/100 mL) determined through dual capillary column headspace gas chromatography with flame ionization detector analysis. Three groups were used in the estimation of the aqueous ethanol wet‐bath simulator solutions uncertainty: GC calibration adjustment, GC analytical, and certified reference material. The standard uncertainties for these uncertainty sources were combined using the method of root‐sum‐squares to give uc = 0.8598%. The combined standard uncertainty was expanded to U = 1.7% to reflect a confidence level of 95% using a coverage factor of 2. This estimation applies to all aqueous ethanol wet‐bath simulator solution concentrations produced by this laboratory. 相似文献

The goal of this paper is to deliver a concise form of discussion on the use of cost‐benefit analysis (CBA) in environmental policy formulation in the scholarships. There have been several critiques from environmental/legal economists and even from economists who are in favor of the use of CBA. The critiques of CBA can be reduced to one statement: ‘numbers don't tell us everything’. The implication from the critiques of CBA is that these evoke cautiousness or wariness against an economized calculation of CBA in the environment policy. CBA can be a valuable tool when it is carefully restricted from being used in policies such as environment, health, and natural resource policy in which inherent incommensurability exists.

ABSTRACTUsing the performance evaluation data of Korean SOEs, the impact of information asymmetry within target setting on ratcheting intensity and the ratchet effect is investigated. It was found that ratcheting intensity is substantially greater (lower) for target-setting methods that have utilized limited (plenty of) information on past performance and that the ratchet effect increases with ratcheting intensity. These results indicate that information asymmetry between the superior and subordinates is one of the crucial drivers of the ratchet effect. It was also documented that when subordinates sufficiently beat target, the ratchet effect is much greater for relatively “top-down” target setting than that for relatively “bottom-up” target setting. This finding suggests that securing subordinates’ active participation in the target-setting process can alleviate their effort reduction incentive. 相似文献

Abstract: One hundred Korean adults (50 men, 50 women) were scanned in the upright position using a cone‐beam CT (CBCT) scanner. The soft tissue (ST) thicknesses were measured at 31 landmarks, 10 midline and 21 bilateral landmark sites, and the means and standard deviations were obtained for male and female subjects. While 18 of 31 landmarks showed sex differences, the majority showed higher values for male subjects with the exception of a few landmark sites corresponding to the zygoma area, which showed smaller values in men than in women. The mandibular area showed greater differences between the right and left sides. Overall, the ST thickness measurements obtained in this study can be used as a database for the forensic craniofacial reconstruction of Korean adult faces. 相似文献

ABSTRACTThe study of formal planning in nonprofits and the public sector is thriving, with management gurus providing abundant advice on its value and proper execution. We address a related, but broader issue: why has the management tool of formal planning become prevalent in organizations with a public goal in the first place? To answer this question, we draw on insights from institutional theories of organization, bringing a fresh perspective to the increasingly common practice of formal planning in the administration of public entities. Using a unique dataset constructed from interviews with a random, representative sample of the leaders of 200 nonprofits in the San Francisco Bay Area, we analyze the factors associated with the presence of a formal plan. We combine the interview data with details on organizational characteristics from tax reports and consider the features of nonprofits that plan using logistic regression. The findings reveal that size and capacity are important, but links to an external, rationalized environment dampen the effects of both. Thus, functional factors, while important, are insufficient to explain why nonprofits engage in planning. For those interested in promoting formal planning as a management tool, our findings provide insight into other organizational features that promote the use of planning. And for those concerned with the potentially deleterious effects of this tool in the nonprofit sector, we show that certain types of organizations seem adept at maintaining a less formal structure. 相似文献
